PRELIMINARY—SUBJECT TO COMPLETION, DATED JULY 19, 2013

JOINT PROXY STATEMENT/PROSPECTUS

To the Shareholders of Mid-America Apartment Communities, Inc. and the Shareholders of Colonial Properties Trust:

The board of directors of Mid-America Apartment Communities, Inc., which we refer to as MAA, and the board of trustees of Colonial Properties Trust, which we refer to as Colonial, have each unanimously approved an agreement and plan of merger, dated as of June 3, 2013, by and among MAA, Mid-America Apartments, L.P., Martha Merger Sub, LP, Colonial and Colonial Realty Limited Partnership, which we refer to as the merger agreement. Pursuant to the merger agreement, MAA and Colonial will combine through a merger of Colonial with and into MAA, with MAA surviving the merger, which we refer to as the parent merger. If completed, we believe the parent merger will create the preeminent Sunbelt-focused multifamily real estate investment trust, or REIT, in the United States with a pro forma total market capitalization of approximately $8.7 billion and a pro forma equity market capitalization of approximately $5.4 billion, each as of June 30, 2013. The combined company, which we refer to as the Combined Corporation, will retain the name “Mid-America Apartment Communities, Inc.” and will continue to trade on the New York Stock Exchange, or NYSE, under the symbol “MAA.” H. Eric Bolton, Jr., will serve as the chairman and chief executive officer of the Combined Corporation following the parent merger. The obligations of MAA and Colonial to effect the parent merger are subject to the satisfaction or waiver of certain conditions set forth in the merger agreement (including the approvals of each company’s shareholders).

If the parent merger is completed pursuant to the merger agreement, each Colonial shareholder will receive 0.360 shares of MAA common stock for each Colonial common share of beneficial interest, which we refer to as Colonial common shares, held immediately prior to the effective time of the parent merger, with cash paid for fractional Colonial common shares. MAA shareholders will continue to hold their existing shares of MAA common stock. The exchange ratio is fixed and will not be adjusted to reflect changes in the price of MAA common stock or the price of Colonial common shares occurring prior to the completion of the parent merger. MAA common stock is currently listed on the NYSE under the symbol “MAA” and Colonial common shares are currently listed on the NYSE under the symbol “CLP.” Based on the closing price of MAA common stock on the NYSE of $67.97 on May 31, 2013, the last trading date before the announcement of the proposed merger, the 0.360 exchange ratio represented approximately $24.47 in MAA common stock for each Colonial common share. Based on the closing price of MAA common stock on the NYSE of $[—] on [—], 2013, the latest practicable date before the date of this joint proxy statement/prospectus, the 0.360 exchange ratio represented approximately $[—] in MAA common stock for each Colonial common share. The value of the merger consideration will fluctuate with changes in the market price of MAA common stock. We urge you to obtain current market quotations for MAA common stock and Colonial common shares.

We anticipate that MAA will issue approximately 31.9 million shares of MAA common stock in connection with the parent merger, will reserve approximately 1.6 million shares of MAA common stock in respect of Colonial equity awards that MAA will assume in connection with the parent merger, and will reserve approximately 2.6 million shares of MAA common stock in respect of the potential conversion of limited partnership units issued by MAA LP to former limited partners of Colonial LP. Upon completion of the parent merger, we estimate that continuing MAA equity holders will own approximately 56% of the issued and outstanding common shares of the Combined Corporation, assuming the conversion of all limited partnership units of MAA LP held by existing limited partners of MAA LP to shares of Combined Corporation common stock, and former Colonial equity holders will own approximately 44% of the issued and outstanding shares of common stock of the Combined Corporation, assuming the conversion to shares of Combined Corporation common stock of all limited partnership units issued by MAA LP to former limited partners of Colonial LP.

MAA and Colonial will each be holding a special meeting of their respective shareholders. At the MAA special meeting, MAA shareholders will be asked to vote on (i) a proposal to approve the merger agreement, the

parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders, (ii) a proposal to approve the MAA 2013 Stock Incentive Plan, and (iii) a proposal to approve one or more adjournments of the MAA special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement, the parent merger and the other transactions contemplated by the merger agreement. At the Colonial special meeting, Colonial shareholders will be asked to vote on (i) a proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger, dated as of June 3, 2013, between MAA and Colonial, and the other transactions contemplated by the merger agreement, (ii) an advisory (non-binding) proposal to approve compensation payable to certain executive officers of Colonial in connection with the parent merger, and (iii) a proposal to approve one or more adjournments of the special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement.

The record date for determining the shareholders entitled to receive notice of, and to vote at, the MAA special meeting and the Colonial special meeting is [—], 2013. The parent merger cannot be completed unless the MAA shareholders and Colonial shareholders each approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement by the affirmative vote of the holders of each of (i) a majority of the outstanding shares of MAA common stock entitled to vote on the parent merger and (ii) a majority of the outstanding Colonial common shares entitled to vote on the parent merger.

The MAA board of directors, which we refer to as the MAA Board, has unanimously (i) determined and declared that the merger agreement, the merger and the other transactions contemplated by the merger agreement, including the issuance of MAA common stock to Colonial shareholders in connection with the parent merger, are advisable and in the best interests of MAA and its shareholders, and (ii) adopted and approved the merger agreement, the parent merger and the other transactions contemplated thereby. The MAA Board unanimously recommends that MAA shareholders vote FOR the proposal to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders, FOR the proposal to approve the MAA 2013 Stock Incentive Plan and FOR the proposal to approve one or more adjournments of the MAA special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement, the parent merger and the other transactions contemplated by the merger agreement.

The Colonial board of trustees, which we refer to as the Colonial Board, has unanimously (i) determined that the parent merger (including the plan of merger) and the other transactions contemplated by the merger agreement are advisable and in the best interests of Colonial and its shareholders, and (ii) approved and adopted the merger agreement and the plan of merger. The Colonial Board unanimously recommends that Colonial shareholders vote FOR the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, FOR the advisory (non-binding) proposal to approve compensation payable to certain executive officers of Colonial in connection with the mergers, and FOR the proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement and the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement.

This joint proxy statement/prospectus contains important information about MAA, Colonial, the parent merger, the merger agreement and the special meetings. This document is also a prospectus for shares of MAA common stock that will be issued to Colonial shareholders pursuant to the merger agreement. We encourage you to read this joint proxy statement/prospectus carefully before voting, including the section entitled “Risk Factors” beginning on page 32.

Your vote is very important, regardless of the number of shares you own. Whether or not you plan to attend the MAA special meeting or the Colonial special meeting, as applicable, please submit a proxy to vote your shares as promptly as possible to make sure that your shares of MAA common stock and/or Colonial common shares, as applicable, are represented at the applicable special meeting. Please review this

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

TO BE HELD ON [—], 2013

To the Shareholders of Colonial Properties Trust:

A special meeting of the shareholders of Colonial Properties Trust, an Alabama real estate investment trust, referred to in this joint proxy statement/prospectus as Colonial, will be held at [—] on [—], 2013 commencing at [—], local time, for the following purposes:

Approval and Adoption of Merger Agreement and Merger. To consider and vote upon a proposal to approve and adopt the Agreement and Plan of Merger, dated as of June 3, 2013, as it may be amended or modified from time-to-time (referred to in the accompanying joint proxy statement/prospectus as the “merger agreement”), by and among Mid-America Apartment Communities, Inc., referred to in the accompanying joint proxy statement/prospectus as MAA, Colonial, Mid-America Apartments, L.P., Martha Merger Sub, LP and Colonial Realty Limited Partnership, pursuant to which, among other things, Colonial will be merged with and into MAA, with MAA surviving the parent merger (referred to in the accompanying joint proxy statement/prospectus as the “parent merger”), the parent merger pursuant to the Plan of Merger (referred to in the accompanying joint proxy statement/prospectus as the “plan of merger”) and the other transactions contemplated by the merger agreement;

Approval of Executive Compensation Payable in Connection with the Merger. To consider and cast an advisory (non-binding) vote upon a proposal to approve compensation payable to certain executive officers of Colonial in connection with the parent merger; and

Adjournment of the Special Meeting. To consider and vote upon a proposal to approve one or more adjournments of the special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of proposal 1.

We do not expect to transact any other business at the Colonial special meeting. Shareholders of record at the close of business on [—], 2013 are entitled to notice of and to vote at the Colonial special meeting and at any adjournment or postponement of the Colonial special meeting.

The merger agreement and plan of merger and the compensation payable under existing arrangements that certain executive officers of Colonial may receive in connection with the parent merger are more fully described in the accompanying joint proxy statement/prospectus, which we encourage you to read carefully and in its entirety before voting. A copy of the merger agreement is included as Annex A to the accompanying joint proxy statement/prospectus, and a copy of the plan of merger is included as Annex B to the accompanying joint proxy statement/prospectus. The accompanying joint proxy statement/prospectus is a part of this notice.

All Colonial shareholders of record are cordially invited to attend the Colonial special meeting. Even if you plan to attend the Colonial special meeting, we urge you to submit a valid proxy promptly. If your Colonial common shares are registered in your own name, you may submit your proxy by (1) filling out and signing the proxy card, and then mailing your signed proxy card in the enclosed postage-paid reply envelope, (2) authorizing the voting of your shares over the Internet at www.proxyvoting.com/colonial, or (3) calling toll free (877) 215-9164 and following the instructions on the enclosed proxy card. If your Colonial common shares are held in “street name,” you should follow the enclosed instructions that your broker, bank, or other nominee has provided.

Your vote is very important regardless of the number of Colonial common shares you own. We cannot complete the merger unless the merger agreement and parent merger pursuant to the plan of merger are approved and adopted by the affirmative vote of the holders of at least a majority of the outstanding Colonial common shares entitled to vote on such proposal. Accordingly, we urge you to review the enclosed materials and request that you complete, sign, date and return, as promptly as possible, the enclosed proxy card in the accompanying postage-paid reply envelope or submit your proxy over the Internet or by telephone.

Under Alabama law, Colonial shareholders who do not vote in favor of the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement will have the right to dissent from the parent merger and obtain payment of the fair value of their shares if the parent merger is consummated, but only if they submit a written notice of their intent to demand payment to Colonial prior to the Colonial special meeting and comply with the other requirements of Article 13 of the Alabama Business Corporation Law (the “ABCL”) explained in the joint proxy statement/prospectus accompanying this notice. A copy of the applicable ABCL statutory provisions is included as Annex H to the accompanying joint proxy statement/prospectus, and a summary of these provisions can be found under “Dissenters’ Rights” in the accompanying joint proxy statement/prospectus.

Colonial’s board of trustees unanimously recommends that you vote FOR approval and adoption of the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement as described in proposal 1, FOR approval, on an advisory (non-binding) basis, of the compensation payable to certain Colonial executive officers described in proposal 2 and FOR approval of one or more adjournments of the special meeting in accordance with proposal 3. Approval of proposals 1, 2 and 3 are subject to separate votes by Colonial’s shareholders, and approval of the compensation arrangements in proposal 2 is not a condition to completion of the parent merger. Since the approval and adoption of the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement in proposal 1 requires the affirmative vote of the holders of at least a majority of the outstanding Colonial common shares entitled to vote on proposal 1, if you fail to vote, if you fail to authorize your broker, bank or other nominee to vote on your behalf, or if you abstain from voting, the effect will be the same as if you had voted against the approval of the Colonial merger proposal.

By Order of the Board of Trustees of Colonial Properties Trust

Q:	What is the proposed transaction?

MAA and Colonial are proposing a combination of their companies through the merger of Colonial with and into MAA, with MAA continuing as the surviving entity, pursuant to the terms of the merger agreement. The Combined Corporation will be named “Mid-America Apartment Communities, Inc.” and the shares of the Combined Corporation common stock will be listed and traded on the NYSE under the symbol “MAA.”

The merger agreement also provides for the merger of OP Merger Sub with and into Colonial LP, with Colonial LP continuing as the surviving entity as an indirect wholly-owned subsidiary of MAA LP.

Q:	What will happen in the proposed transaction?

A:	As a result of the parent merger, each issued and outstanding Colonial common share (other than shares with respect to which dissenters’ rights have been properly exercised and not withdrawn under applicable

law) will be converted automatically into the right to receive 0.360 shares of common stock, par value $0.01 per share, of the Combined Corporation, as described under “The Merger Agreement—Merger Consideration; Effects of the Parent Merger and the Partnership Merger” beginning on page 148. Colonial shareholders will not receive any fractional shares of MAA common stock in the parent merger. Instead, Colonial shareholders will be paid cash (without interest) in lieu of any fractional share interest to which they would otherwise be entitled.

As a result of the partnership merger, each outstanding limited partnership interest in Colonial LP will be converted automatically into 0.360 limited partnership units in MAA LP.

Q:	How will MAA shareholders be affected by the parent merger and the issuance of shares of MAA common stock to Colonial shareholders in the parent merger?

After the mergers, each MAA shareholder will continue to own the shares of MAA common stock that the shareholder held immediately prior to the parent merger. As a result, each MAA shareholder will own shares of common stock in the Combined Corporation, a larger company with more assets. However, because MAA will be issuing new shares of MAA common stock to Colonial shareholders in the parent merger, each outstanding share of MAA common stock immediately prior to the parent merger will represent a smaller percentage of the aggregate number of shares of Combined Corporation common stock outstanding after the mergers. Upon completion of the parent merger, we estimate that continuing MAA equity holders will own approximately 56% of the issued and outstanding shares of Combined Corporation common stock, assuming the conversion of all limited partnership units of MAA LP held by existing limited partners of MAA LP to shares of Combined Corporation common stock, and former Colonial equity holders will own approximately 44% of the issued and outstanding shares of common stock of the Combined Corporation, assuming the conversion to shares of Combined Corporation common stock of all limited partnership units issued by MAA LP to former limited partners of Colonial LP.

Q:	What happens if the market price of shares of MAA common stock or Colonial common shares changes before the closing of the parent merger?

No change will be made to the exchange ratio of 0.360 if the market price of shares of MAA common stock or Colonial common shares changes before the parent merger. Because the exchange ratio is fixed, the value of the consideration to be received by Colonial shareholders in the parent merger will depend on the market price of shares of MAA common stock at the time of the parent merger.

Q:	Why am I receiving this joint proxy statement/prospectus?

The MAA Board and the Colonial Board are using this joint proxy statement/prospectus to solicit proxies of MAA and Colonial shareholders in connection with the merger agreement and the parent merger. In addition, MAA is using this joint proxy statement/prospectus as a prospectus for Colonial shareholders because MAA is offering shares of its common stock to be issued in exchange for Colonial common shares in the parent merger. The parent merger cannot be completed unless:

•

the holders of MAA common stock vote to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger; and

•

the holders of Colonial common shares vote to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement.

Each of MAA and Colonial will hold separate meetings of their respective shareholders to obtain these approvals and to consider other proposals as described elsewhere in this joint proxy statement/prospectus.

This joint proxy statement/prospectus contains important information about the parent merger and the other proposals being voted on at the shareholder meetings and you should read it carefully. The enclosed voting materials allow you to vote your shares of MAA common stock and/or Colonial common shares, as applicable, without attending your company’s shareholders’ meeting.

Your vote is important. You are encouraged to submit your proxy as promptly as possible.

Q:	Am I being asked to vote on any other proposals at the shareholder meetings in addition to the parent merger proposal?

A:	MAA. At the MAA special meeting, MAA shareholders will be asked to consider and vote upon the following additional proposals:

•

A proposal to approve the MAA 2013 Stock Incentive Plan to replace the Mid-America Apartment Communities, Inc. 2004 Stock Plan, which expires by its terms on October 31, 2013; and

•

A proposal to adjourn the MAA special meeting, if necessary to approve one or more adjournments of the special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement, the parent merger and the other transactions contemplated by the merger agreement.

Colonial. At the Colonial special meeting, Colonial shareholders will be asked to consider and vote upon the following additional proposals:

•

An advisory (non-binding) proposal to approve compensation payable to certain executive officers of Colonial in connection with the mergers; and

•

A proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement.

Q:	Why are MAA and Colonial proposing the mergers?

Among other reasons, the MAA Board and the Colonial Board believe that the mergers will create the pre-eminent Sunbelt-focused multifamily real estate investment trust, referred to herein as a REIT, that will own approximately 85,000 apartment units in 285 communities, representing the second largest publicly-traded REIT portfolio of owned apartments. The Combined Corporation is expected to have significant liquidity, greater access to multiple forms of capital, an improved investment grade rating with limited near-term debt maturities and a lower cost of capital than either MAA or Colonial on a standalone basis. The increased size and diversification of the Combined Corporation’s portfolio is expected to enhanced its competitive advantage across the Sunbelt region, and synergies and advantages generated by the mergers are expected to drive higher margins. To review the reasons of the MAA Board and the Colonial Board for the mergers in greater detail, see “The Parent Merger—Recommendation of the MAA Board and Its Reasons for the Parent Merger” beginning on page 87 and “The Parent Merger—Recommendation of the Colonial Board and Its Reasons for the Parent Merger” beginning on page 91.

Q:	Who will be the board of directors and management of the Combined Corporation after the parent merger?

At the effective time of the parent merger, the number of directors that comprise the board of directors of the Combined Corporation will be twelve, with all seven of the members of the MAA Board immediately prior to the completion of the parent merger, H. Eric Bolton, Jr., Alan B. Graf, Jr., Ralph Horn, Philip W. Norwood, W. Reid Sanders, William B. Sansom and Gary Shorb, continuing as directors of the Combined

Corporation. In addition, five current members of the Colonial Board, Thomas H. Lowder, James K. Lowder, Claude B. Nielsen, Harold W. Ripps and John W. Spiegel, will join the board of directors of the Combined Corporation. Alan B. Graf, Jr. and Ralph Horn, Co-Lead Independent Directors for MAA, will serve as Co-Lead Independent Directors for the Combined Corporation.

H. Eric Bolton, Jr., MAA’s Chief Executive Officer and Chairman of the Board of Directors, will serve as Chief Executive Officer and Chairman of the Board of Directors of the Combined Corporation. Albert M. Campbell, III, MAA’s Chief Financial Officer, will serve as Chief Financial Officer of the Combined Corporation, and Thomas L. Grimes, Jr., MAA’s Chief Operating Officer, will serve as the Chief Operating Officer of the Combined Corporation.

Q:	Will MAA and Colonial continue to pay distributions prior to the effective time of the parent merger?

Yes. The merger agreement permits MAA to continue to pay a regular quarterly distribution, in accordance with past practice at a rate not to exceed $0.695 per quarter, and any distribution that is reasonably necessary to maintain its REIT qualification and/or to avoid the imposition of U.S. federal income or excise tax. The merger agreement permits Colonial to pay a regular quarterly distribution, in accordance with past practice at a rate not to exceed $0.21 per quarter, and any distribution that is reasonably necessary to maintain its REIT qualification and/or to avoid the imposition of U.S. federal income or excise tax. The timing of quarterly dividends will be coordinated by MAA and Colonial so that that if either the MAA shareholders or the Colonial shareholders receive a dividend for any particular quarter prior to the closing the mergers, the shareholders of the other entity will also receive a dividend for that quarter prior to the closing of the mergers.

Q:	When and where are the shareholder meetings?

A:	The MAA special meeting will be held at [—] on [—], 2013 commencing at [—], local time.

The Colonial special meeting will be held at [—] on [—], 2013 commencing at [—], local time.

Colonial. Colonial’s bylaws provide that the presence, in person or by proxy, of shareholders entitled to cast a majority of all the votes entitled to be cast at such meeting will constitute a quorum.

Q:	What vote is required to approve the proposals?

MAA.

•

Q:	How does the MAA Board recommend that MAA shareholders vote on the proposals?

After careful consideration, the MAA Board has unanimously determined and declared that the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger, are advisable and in the best interests of MAA and its shareholders and approved and adopted the merger agreement, the parent merger and the other transactions contemplated by the merger agreement. The MAA Board unanimously recommends that MAA shareholders vote FOR the proposal to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger, FOR the proposal to approve the MAA 2013 Stock Incentive Plan and FOR the proposal to approve one or more adjournments of the MAA special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement and the parent merger.

For a more complete description of the recommendation of the MAA Board, see “The Parent Merger—Recommendation of the MAA Board and Its Reasons for the Parent Merger” beginning on page 87.

Q:	How does the Colonial Board recommend that Colonial shareholders vote on the proposals?

The Colonial Board has unanimously determined that the parent merger (including the plan of merger) and the other transactions contemplated by the merger agreement are advisable and in the best interests of Colonial and its shareholders, and approved and adopted the merger agreement and the plan of merger. The

Colonial Board unanimously recommends that Colonial shareholders vote FOR the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, FOR the advisory (non-binding) proposal to approve compensation payable to certain executive officers of Colonial in connection with the mergers, and FOR the proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of the proposal to approve and adopt the merger agreement and the parent merger pursuant to the plan of merger.

For a more complete description of the recommendation of the Colonial Board, see “The Parent Merger—Recommendation of the Colonial Board and Its Reasons for the Parent Merger” beginning on page 91.

Q:	Have any shareholders already agreed to approve the mergers?

Pursuant to separate voting agreements, certain directors, officers and shareholders of MAA, who together as of July 16, 2013 owned approximately 0.36% of the outstanding shares of MAA common stock, have agreed to vote in favor of the parent merger and the other transactions contemplated by the merger agreement, and certain limited partners of MAA LP, who together as of July 16, 2013 owned approximately 37.30% of the outstanding limited partnership interests of MAA LP, have agreed to vote in favor of the partnership merger, the other transactions contemplated by the merger agreement and the amendment and restatement of the limited partnership agreement of MAA LP, subject to the terms and conditions of the respective voting agreements, as described under “Voting Agreements” beginning on page 168.

Pursuant to separate voting agreements, certain trustees, officers and shareholders of Colonial, who together as of July 16, 2013 owned approximately 3.9% of the outstanding Colonial common shares, have agreed to vote in favor of the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, subject to the terms and conditions of the respective voting agreements, as described under “Voting Agreements” beginning on page 168.

Q:	Are there any conditions to closing of the mergers that must be satisfied for the mergers to be completed?

In addition to the approvals of the shareholders of each of MAA and Colonial of the parent merger and the other transactions contemplated by the merger agreement, there are a number of conditions that must be satisfied or waived for the mergers to be consummated. Among other things, the partnership merger and the amendment and restatement of the limited partnership agreement of MAA LP must be approved by the holders of at least 66²/₃rds of the outstanding limited partnership interests of MAA LP, excluding for purposes of the approval all limited partnership interests held by MAA. For a description of all of the conditions to the mergers, see “The Merger Agreement—Conditions to Completion of the Mergers” beginning on page 161.

Q:	Are there risks associated with the parent merger that I should consider in deciding how to vote?

A:	Yes. There are a number of risks related to the parent merger that are discussed in this joint proxy statement/ prospectus described in the section entitled “Risk Factors” beginning on page 32.

Q:	If my shares of MAA common stock or my Colonial common shares are held in “street name” by my broker, bank or other nominee, will my broker, bank or other nominee vote my shares of MAA common stock or my Colonial common shares for me?

No. Unless you instruct your broker, bank or other nominee how to vote your shares of MAA common stock and/or your Colonial common shares, as applicable, held in street name, your shares will NOT be voted. This is referred to as a “broker non-vote.” If you hold your shares of MAA common stock and/or your Colonial common shares in a stock brokerage account or if your shares are held by a bank or other nominee (that is, in street name), you must provide your broker, bank or other nominee with instructions on how to vote your shares.

Q:	What happens if I do not vote for a proposal?

A:	MAA. If you are a MAA shareholder and fail to vote, fail to instruct your broker, bank or nominee to vote, or abstain from voting:

•

with respect to the proposal to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger, it will have the same effect as a vote “AGAINST” this proposal;

•

with respect to the MAA 2013 Stock Incentive Plan proposal, if you abstain it will count as a vote cast with respect to this proposal and accordingly, abstentions will be included in determining whether the NYSE voting requirement has been achieved, but if the NYSE voting requirement is achieved, it will have no effect on the outcome of the vote for this proposal; if you fail to vote or fail to instruct your broker, bank or nominee to vote, it will not be counted as votes cast on this proposal and accordingly, it will make it more difficult for the NYSE voting requirement to be achieved, but if the NYSE voting requirement is achieved, it will have no effect on the outcome of the vote for this proposal; and

•

with respect to the adjournment proposal, it will have no effect on the outcome of the vote for this proposal.

Colonial. If you are a Colonial shareholder and fail to vote, fail to instruct your broker, bank or nominee to vote, or abstain from voting:

•

with respect to the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, it will have the same effect as a vote “AGAINST” this proposal;

•

with respect to the advisory (non-binding) proposal to approve compensation payable to certain executive officers of Colonial in connection with the mergers, an abstention from voting will have the same effect as voting “AGAINST” this proposal; if you fail to vote or fail to instruct your broker, bank or nominee to vote, your Colonial common shares will not affect whether this proposal is approved; and

•

with respect to the adjournment proposal, an abstention from voting will have the same effect as voting “AGAINST” this proposal; if you fail to vote or fail to instruct your broker, bank or nominee to vote, your Colonial common shares will not affect whether this proposal is approved.

Q:	Will my rights as a shareholder change as a result of the parent merger?

The rights of the MAA shareholders will be substantially unchanged as a result of the parent merger. Colonial shareholders will have different rights following the effective time of the parent merger due to the differences between the governing documents of MAA and Colonial. At the effective time of the parent merger, the charter and bylaws of MAA will thereafter be the charter and bylaws of the Combined Corporation. For more information regarding the differences in shareholder rights, see “Comparison of Rights of Shareholders of MAA and Shareholders of Colonial” beginning on page 182.

Q:	When are the mergers expected to be completed?

MAA and Colonial expect to complete the mergers as soon as reasonably practicable following satisfaction of all of the required conditions. If the shareholders of both MAA and Colonial approve the mergers, and if the other conditions to closing the mergers are satisfied or waived, it is expected that the mergers will be completed in the third quarter of 2013. However, there is no guaranty that the conditions to the mergers will be satisfied or that the mergers will close.

Q:	Do I need to do anything with my share certificates now?

No. You should not submit your share certificates at this time. After the parent merger is completed, if you held Colonial common shares, the exchange agent for the Combined Corporation will send you a letter of transmittal and instructions for exchanging your Colonial common shares for shares of the Combined Corporation common stock pursuant to the terms of the merger agreement. Upon surrender of a certificate or book-entry share for cancellation along with the executed letter of transmittal and other required documents described in the instructions, a Colonial shareholder will receive shares of common stock of the Combined Corporation pursuant to the terms of the merger agreement.

If you are a MAA shareholder, you are not required to take any action with respect to your MAA shares. Such shares will represent shares of the Combined Corporation after the parent merger.

Q:	What are the anticipated U.S. federal income tax consequences to me of the proposed parent merger?

It is intended that the parent merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which is referred to herein as the Code. The closing of the parent merger is conditioned on the receipt by each of MAA and Colonial of an opinion from its respective counsel to the effect that the parent merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Assuming that the parent merger qualifies as a reorganization, U.S. holders of Colonial common shares generally will not recognize gain or loss for U.S. federal income tax purposes upon the receipt of Combined Corporation common stock in exchange for Colonial common shares in connection with the parent merger, except with respect to cash received in lieu of fractional shares of Combined Corporation common stock. Holders of Colonial common shares should read the discussion under the heading “The Parent Merger—Material U.S. Federal Income Tax Consequences of the Parent Merger” beginning on page 122 and consult their tax advisors to determine the tax consequences to them (including the application and effect of any state, local or non-U.S. income and other tax laws) of the parent merger.

Q:	Are MAA and Colonial shareholders entitled to appraisal rights?

Each shareholder of an Alabama real estate investment trust has the same appraisal rights as a shareholder of an Alabama business corporation under the Alabama Business Corporation Law, or ABCL. Pursuant to the ABCL, holders of Colonial common shares are entitled to dissent and demand payment for their shares at “fair value” plus accrued interest. MAA’s obligation to close the mergers will be conditioned on holders of no more than 15% of the outstanding Colonial common shares properly perfecting their right to dissent and demand cash payment for their Colonial common shares.

MAA shareholders are not entitled to exercise dissenters’ rights in connection with the parent merger. See “Dissenters’ Rights” beginning on page 173 for more information on the applicable provisions of the ABCL.

Q:	What do I need to do now?

After you have carefully read this joint proxy statement/prospectus, please respond by completing, signing and dating your proxy card or voting instruction card and returning it in the enclosed preaddressed postage-paid envelope or, if available, by submitting your proxy by one of the other methods specified in your proxy card or voting instruction card as promptly as possible so that your shares of MAA common stock and/or your Colonial common shares will be represented and voted at the MAA special meeting or the Colonial special meeting, as applicable.

Please refer to your proxy card or voting instruction card forwarded by your broker, bank or other nominee to see which voting options are available to you.

The method by which you submit a proxy will in no way limit your right to vote at the MAA special meeting or the Colonial special meeting, as applicable, if you later decide to attend the meeting in person.

However, if your shares of MAA common stock or your Colonial common shares are held in the name of a broker, bank or other nominee, you must obtain a legal proxy, executed in your favor, from your broker, bank or other nominee, to be able to vote in person at the MAA special meeting or the Colonial special meeting, as applicable.

Q:	How will my proxy be voted?

All shares of MAA common stock entitled to vote and represented by properly completed proxies received prior to the MAA special meeting, and not revoked, will be voted at the MAA special meeting as instructed on the proxies. If you properly sign, date and return a proxy card, but do not indicate how your shares of MAA common stock should be voted on a matter, the shares of MAA common stock represented by your proxy will be voted as the MAA Board recommends and therefore FOR the proposal to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger, FOR the proposal to approve the MAA 2013 Stock Incentive Plan, and FOR the proposal to adjourn the MAA special meeting, if necessary or appropriate in the view of the MAA Board, to solicit additional proxies in favor of the proposals if there are not sufficient votes at the time of such adjournment to approve such proposals. If you do not provide voting instructions to your broker, bank or other nominee, your shares of MAA common stock will NOT be voted at the MAA special meeting and will be considered broker non-votes.

All Colonial common shares entitled to vote and represented by properly completed proxies received prior to the Colonial special meeting, and not revoked, will be voted at the Colonial special meeting as instructed on the proxies. If you properly sign, date and return a proxy card, but do not indicate how your Colonial common shares should be voted on a matter, the Colonial common shares represented by your proxy will be voted as the Colonial Board recommends and therefore FOR the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, FOR the advisory (non-binding) proposal to approve compensation payable to certain executive officers of Colonial in connection with the mergers and FOR the proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement. If you do not provide voting instructions to your broker, bank or other nominee, your Colonial common shares will NOT be voted at the Colonial special meeting and will be considered broker non-votes.

Q:	Can I revoke my proxy or change my vote after I have delivered my proxy?

A:	Yes. You may revoke your proxy or change your vote at any time before your proxy is voted at the MAA special meeting or the Colonial special meeting, as applicable. If you are a holder of record, you can do this in any of the three following ways:

•

by sending a written notice to the corporate Secretary of MAA or the corporate Secretary of Colonial, as applicable, in time to be received before the MAA special meeting or the Colonial special meeting, as applicable, stating that you would like to revoke your proxy;

•

The Mergers

The Merger Agreement (See page 147)

MAA, MAA LP, OP Merger Sub, Colonial and Colonial LP have entered into the merger agreement attached as Annex A to this joint proxy statement/prospectus, which is incorporated herein by reference. MAA and Colonial encourage you to carefully read the merger agreement in its entirety because it is the principal document governing the merger and the other transactions contemplated by the merger agreement.

The Mergers (See page 67)

Subject to the terms and conditions of the merger agreement, at the effective time of the parent merger, Colonial will merge with and into MAA, which is referred to herein as the parent merger, with MAA surviving the parent merger, which is referred to herein as the Combined Corporation. The shares of common stock of the Combined Corporation are expected to be listed and traded on the NYSE under the symbol “MAA.” The merger agreement also provides for the merger, prior to the parent merger, of OP Merger Sub, a subsidiary of MAA LP, with and into Colonial LP with Colonial LP continuing as the surviving entity and an indirectly wholly owned subsidiary of MAA LP, which is referred to herein as the partnership merger, and, together with the parent merger, are referred to herein as the mergers.

Upon completion of the parent merger, we estimate that continuing MAA equity holders will own approximately 56% of the issued and outstanding common shares of the Combined Corporation, assuming the conversion of all limited partnership units of MAA LP held by existing limited partners of MAA LP to shares of Combined Corporation common stock, and former Colonial equity holders will own approximately 44% of the issued and outstanding shares of common stock of the Combined Corporation, assuming the conversion to shares of Combined Corporation common stock of all limited partnership units issued by MAA LP to former limited partners of Colonial LP.

The Merger Consideration (See page 148)

In the parent merger, each Colonial common share (other than shares with respect to which dissenters’ rights have been properly exercised and not withdrawn under applicable law) issued and outstanding immediately prior to the effective time of the parent merger will be converted into the right to receive 0.360 shares of MAA common stock. The exchange ratio is fixed and will not be adjusted for changes in the market value of MAA common stock or Colonial common shares. Because of this, the implied value of the consideration to be received by Colonial shareholders in the parent merger will fluctuate between now and the completion of the mergers. Based on MAA’s closing price of $67.97 per share on May 31, 2013, the last trading day before the announcement of the proposed merger, the exchange ratio represented approximately $24.47 in MAA common stock for each Colonial common share. Based on MAA’s closing price of $[—] per share on [—], 2013, the latest practicable trading day before the date of this joint proxy statement/prospectus, the exchange ratio represented approximately $[—] in MAA common stock for each Colonial common share.

You are urged to obtain current market prices of shares of MAA common stock and Colonial common shares. You are cautioned that the trading price of the common stock of the Combined Corporation after the mergers may be affected by factors different from those currently affecting the trading prices of MAA common stock and Colonial common shares, and therefore, the historical trading prices of MAA and Colonial may not be indicative of the trading price of the Combined Corporation. See the risks related to the mergers and the related transactions described under the section “Risk Factors—Risk Factors Relating to the Mergers” beginning on page 32.

Voting Agreements (See page 168)

Concurrently with the execution of the merger agreement, Colonial and Colonial LP entered into separate Voting Agreements with H. Eric Bolton, Jr., MAA’s Chairman and Chief Executive Officer, W. Reid Sanders, a member of the MAA Board, and another shareholder of MAA who is not a director or officer of MAA, and MAA and MAA LP entered into separate Voting Agreements with Thomas H. Lowder, James K. Lowder and Harold W. Ripps, each members of the Colonial Board. As of July 16, 2013, the MAA directors and shareholders who are a party to a Voting Agreement with Colonial and Colonial LP collectively owned approximately 0.36% of the outstanding shares of MAA common stock and approximately 37.30% of the outstanding limited partnership units in MAA LP, and the Colonial trustees who are a party to a Voting Agreement with MAA and MAA LP

collectively owned approximately 3.9% of the outstanding Colonial common shares and approximately 3.5% of the outstanding limited partnership units in Colonial LP (including the limited partnership units held by Colonial).

Pursuant to the terms of the Voting Agreements, each of the shareholder parties thereto has agreed, subject to the terms and conditions contained in each Voting Agreement, to among other things, vote all of his shares of MAA common stock, Colonial common shares, limited partnership units in MAA LP or, in the event of any vote by limited partners of Colonial LP, limited partnership units in Colonial LP, as applicable, whether currently owned or acquired at any time prior to the termination of the applicable Voting Agreement, in favor of the mergers and against any other Acquisition Proposal (as defined in the “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions” on page 156) for MAA or Colonial, as applicable, any action or agreement that would reasonably be expected to result in any condition to the consummation of the mergers not being fulfilled, and any action that could reasonably be expected to impede or materially adversely affect consummation of the transactions contemplated by the merger agreement.

Each of the shareholder parties to the Voting Agreements has also agreed to comply with certain restrictions on the transfer of his shares subject to the Voting Agreement. Each Voting Agreement entered into with MAA shareholders terminates upon the earliest to occur of: (1) the later to occur of (A) the approval and adoption of the merger agreement at the MAA special meeting, and (B) the approval of the merger agreement by the holders of limited partnership units in MAA LP; and (2) the termination of the merger agreement pursuant to its terms. Each Voting Agreement entered into with Colonial shareholders terminates upon the earliest to occur of: (1) the approval and adoption of the merger agreement at the Colonial special meeting; and (2) the termination of the merger agreement pursuant to its terms.

The foregoing summary of the Voting Agreements is subject to, and qualified in its entirety by reference to, the full text of each of the Voting Agreements. Copies of the Forms of Voting Agreement are attached as Annex C and Annex D to this joint proxy statement/prospectus and are incorporated herein by reference. For more information see “Voting Agreements” beginning on page 168.

The MAA Board unanimously recommends that MAA shareholders vote FOR the MAA merger proposal, FOR the proposal to approve the MAA 2013 Stock Incentive Plan and FOR the proposal to approve one or more adjournments of the special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement and the parent merger.

Recommendation of the Colonial Board (See page 91)

Treatment of the Colonial Equity Incentive Plans (See page 149)

At the effective time of the parent merger, the Combined Corporation will assume all outstanding options, whether or not exercisable, and restricted share awards subject to their current terms under the Colonial equity incentive plans, as adjusted for the exchange ratio. Each option so assumed by the Combined Corporation will continue to have the same terms and conditions (including vesting schedule) as were applicable under the Colonial equity incentive plans prior to the effective time of the parent merger

As of the effective time of the parent merger, all Colonial common shares subject to vesting and other restrictions under the Colonial equity incentive plans will convert into the right to receive shares of Combined Corporation common stock that are subject to the same vesting conditions and other terms and conditions as are applicable to such shares of Colonial restricted shares immediately prior to the effective time of the parent merger, as adjusted for the exchange ratio.

See “The Merger Agreement—Merger Consideration; Effects of the Parent Merger and the Partnership Merger—Assumption of Colonial Equity Incentive Plans by MAA” beginning on page 149.

Directors and Management of MAA After the Mergers (See page 148)

Immediately following the effective time of the parent merger, the MAA Board will be increased to 12 members, with the seven current MAA directors, H. Eric Bolton, Jr., Alan B. Graf, Jr., Ralph Horn, Philip W. Norwood, W. Reid Sanders, William B. Sansom and Gary Shorb, continuing as directors of the Combined Corporation. Alan B. Graf, Jr. and Ralph Horn, Co-Lead Independent Directors for MAA, will serve as Co-Lead Independent Directors for the Combined Corporation.

Nielsen, Harold W. Ripps and John W. Spiegel, which members are referred to herein as the Colonial designees, to serve until the 2014 annual meeting of MAA’s shareholders (and until their successors have been duly elected and qualified).

Interests of MAA’s Directors and Executive Officers in the Mergers (See page 115)

In considering the recommendation of the MAA Board to approve the parent merger and the other transactions contemplated by the merger agreement, MAA shareholders should be aware that certain executive officers and directors of MAA have certain interests in the mergers that may be different from, or in addition to, the interests of MAA shareholders generally. These interests may create potential conflicts of interest. The MAA Board was aware of those interests and considered them, among other matters, in reaching its decision to approve the merger agreement and the transactions contemplated thereby.

Interests of Colonial’s Trustees and Executive Officers in the Mergers (See page 116)

the mergers that may be different from, or in addition to, the interests of Colonial shareholders generally. These interests may create potential conflicts of interest. The Colonial Board was aware of those interests and considered them, among other matters, in reaching its decision to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the transactions contemplated by the merger agreement.

Listing of Shares of the Combined Corporation Common Stock; Delisting and Deregistration of Colonial Common Shares (See page 146)

It is a condition to the completion of the mergers that the shares of MAA common stock issuable in connection with the parent merger be approved for listing on the NYSE, subject to official notice of issuance. After the parent merger is completed, the Colonial common shares currently listed on the NYSE will cease to be listed on the NYSE and will be deregistered under the Exchange Act.

Shareholder Dissenters’ Rights in the Parent Merger (See page 173)

Each shareholder of an Alabama real estate investment trust has the same appraisal rights as a shareholder of an Alabama business corporation under the Alabama Business Corporation Law, or the ABCL, holders of Colonial common shares are entitled to dissent and demand payment for their shares at “fair value” plus accrued interest. See “Dissenters’ Rights” beginning on page 173. MAA’s obligation to close the mergers will be conditioned on holders of no more than 15% of Colonial common shares properly perfecting their right to dissent and demand cash payment for their shares.

Conditions to Completion of the Mergers (See page 161)

A number of conditions must be satisfied or waived, where legally permissible, before the mergers can be consummated. These include, among others:

•

approval of the merger agreement, the parent merger and the other transactions contemplated by the merger agreement by MAA shareholders and Colonial shareholders;

•

approval of the partnership merger and the amendment and restatement of the MAA LP limited partnership agreement by the holders of at least 66 2/3rds of the outstanding limited partnership interests of MAA LP, excluding for purposes of the approval all limited partnership interests held by MAA;

•

a Form S-4 will have been declared effective and no stop order suspending the effectiveness of such Form S-4 will have been issued and remain in effect and no proceeding to that effect shall have been commenced or threatened by the SEC and not withdrawn;

•

the absence of any order or injunction issued by any governmental authority or other legal restraint or prohibition preventing the consummation of the mergers or the other transactions contemplated by the merger agreement;

•

the shares of MAA common stock to be issued in connection with the parent merger will have been approved for listing on the NYSE, subject to official notice of issuance at or prior to the closing of the mergers;

•

the transfer of certain assets held directly by MAA to MAA LP will have occurred; and

•

certain third party consents and approvals being obtained and remaining in full force and effect, except where the failure to obtain the consent or approval would not be reasonably likely to have a material adverse effect on Colonial or MAA.

As of the date of this joint proxy statement/prospectus, all of the third party consents and approvals required as a condition to the obligation of the parties to complete the mergers as described in the final bullet point above had been obtained and not rescinded.

Neither MAA nor Colonial can give any assurance as to when or if all of the conditions to the consummation of the mergers will be satisfied or waived or that the mergers will occur.

For more information regarding the conditions to the consummation of the mergers and a complete list of such conditions, see “The Merger Agreement—Conditions to Completion of the Mergers” beginning on page 161.

Regulatory Approvals Required for the Mergers (See page 122)

MAA and Colonial are not aware of any material federal or state regulatory requirements that must be complied with, or approvals that must be obtained, in connection with the mergers or the other transactions contemplated by the merger agreement. See “The Parent Merger—Regulatory Approvals Required for the Mergers” beginning on page 122.

No Solicitation and Change in Recommendation (See page 156)

Under the merger agreement, each of MAA and Colonial has agreed it will not, nor will it permit any of its subsidiaries to, authorize or permit any of its officers, trustees, directors or employees, and will use its reasonable best efforts to cause its and its subsidiaries’ representatives not to, directly or indirectly, (i) initiate, solicit or knowingly encourage or knowingly facilitate any inquiries or the making of any proposal or offer by or with a third party with respect to an Acquisition Proposal, (ii) engage in any negotiations concerning, or provide any confidential information or data to any person relating to an Acquisition Proposal, or knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal, (iii) approve or execute or enter into any letter of intent, agreement in principle, merger agreement, asset purchase or share exchange agreement, option agreement or other similar agreement related to any Acquisition Proposal, or (iv) propose publicly or agree to do any of the foregoing.

However, prior to the approval of the parent merger and the other transactions contemplated by the merger agreement by their respective shareholders, each of MAA and Colonial may, under certain specified circumstances, engage in discussions or negotiations with and provide nonpublic information regarding itself to a third party making an unsolicited, bona fide written competing Acquisition Proposal. Under the merger agreement, Colonial is required to notify MAA promptly, and MAA is required to notify Colonial promptly, if it receives any Acquisition Proposal or inquiry or any request for nonpublic information in connection with an Acquisition Proposal.

Before the approval of the mergers and the other transactions contemplated by the merger agreement by their respective shareholders, each of the MAA Board and the Colonial Board may, under certain specified circumstances, withdraw its recommendation to its shareholders with respect to the merger if it determines in good faith, after consultation with outside legal counsel, that failure to take such action would be inconsistent with the directors’ or trustees’, as applicable, duties under applicable law. For more information regarding the limitations on MAA, the MAA Board, Colonial and the Colonial Board to consider other Acquisition Proposals, see “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions” beginning on page 156.

Termination of the Merger Agreement (See page 164)

The merger agreement may be terminated at any time before the effective time of the partnership merger by the mutual consent of MAA and Colonial in a written instrument, which action must be taken or authorized by the MAA Board and the Colonial Board.

In addition, either MAA or Colonial (so long as they are not at fault) may decide to terminate the merger agreement if (provided such action must be taken or authorized by the MAA Board or the Colonial Board, as applicable):

•

a governmental authority of competent jurisdiction has issued an order, decree or ruling or taken any other action permanently enjoining or otherwise prohibiting the mergers, and such order, decree, ruling or other action has become final and nonappealable (provided that this termination right will not be available to a party whose failure to comply with any provision of the merger agreement was the cause of, or resulted in, such action);

•

the mergers have not been consummated on or before 5:00 p.m. (New York time) December 31, 2013 (provided that this termination right will not be available to a party whose failure to comply with any provision of the merger agreement has been the cause of, or resulted in, the failure of the mergers to occur on or before such date);

•

there has been a breach by the other party of any of the covenants or agreements or any of the representations or warranties set forth in the merger agreement on the part of such other party, which breach, either individually or in the aggregate, would result in, if occurring or continuing on the closing date, the failure to be satisfied of certain closing conditions, unless such breach is reasonably capable of being cured, and the other party continues to use its reasonable best efforts to cure such breach prior to December 31, 2013 (provided that this termination right will not be available to a party that is in breach of any of its own respective representations, warranties, covenants or agreements set forth in the merger agreement such that certain closing conditions are not satisfied);

•

shareholders of either MAA or Colonial fail to approve the parent merger and the other transactions contemplated by the merger agreement at the duly convened MAA special meeting or Colonial special meeting, as applicable (provided that this termination right will not be available to a party if the failure to obtain that party’s shareholder approval was primarily due to that party’s material breach of certain provisions of the merger agreement); or

•

holders of at least 66 2/3rds of the outstanding limited partnership interests of MAA LP, excluding for purposes of the approval all limited partnership interests held by MAA, fail to approve the partnership merger, the other transactions contemplated by the merger agreement and the amendment and restatement of the MAA LP limited partnership agreement prior to, or contemporaneously with, the MAA special meeting (provided that this termination right will not be available to MAA where a failure to obtain the approval of holders of limited partnership units in MAA LP was primarily caused by any action or failure to act of a MAA party that constitutes a material breach of the merger agreement).

MAA may also decide to terminate the merger agreement if:

•

at any time prior to the approval of the parent merger and the other transactions contemplated by the merger agreement by the MAA shareholders, in order to enter into any alternative acquisition agreement with respect to a Superior Proposal (as defined below in “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions”); provided, that such termination will be null and void unless MAA concurrently pays the termination fee plus the expense reimbursement described below under “—Termination Fee and Expenses Payable by MAA to Colonial”; or

•

(i) the Colonial Board has made a Colonial board change in recommendation and MAA terminates the merger agreement within 10 business days of the date MAA receives notice of the change, or (ii) the Colonial parties have materially breached any of their obligations under the provisions of the merger agreement regarding no solicitation of transactions by the Colonial parties (other than any immaterial or inadvertent breaches thereof not intended to result in an Acquisition Proposal).

Colonial has reciprocal termination rights with respect to the merger agreement as MAA described above.

For more information regarding the rights of MAA and Colonial to terminate the merger agreement, see “The Merger Agreement—Termination of the Merger Agreement” beginning on page 164.

Termination Fee and Expenses (See page 165)

Generally, all fees and expenses incurred in connection with the mergers and the transactions contemplated by the merger agreement will be paid by the party incurring those fees and expenses. However, if the merger agreement is terminated because either party fails to obtain the approval of its shareholders, among other reasons, such party will be required to pay the other party reasonable documented out-of-pocket expenses actually incurred up to a maximum of $10 million. In certain other circumstances, either MAA or Colonial may be obligated to pay the other a termination fee of $75 million plus reasonable documented out-of-pocket expenses actually incurred up to a maximum of $10 million.

For more information regarding the termination fee and expense reimbursement, see “The Merger Agreement—Termination of the Merger Agreement—Termination Fee and Expenses Payable by Colonial to MAA” beginning on page 165 and “The Merger Agreement—Termination of the Merger Agreement—Termination Fee and Expenses Payable by MAA to Colonial” beginning on page 166.

Litigation Relating to the Mergers (See page 146)

On June 19, 2013, a putative class action and derivative lawsuit was filed in the Circuit Court for Jefferson County, Alabama against and purportedly on behalf of Colonial captioned Williams v. Colonial Properties Trust, et al. The complaint names as defendants Colonial, the members of the Colonial Board, Colonial LP, MAA, MAA LP and OP Merger Sub and alleges that the trustees of Colonial breached their fiduciary duties by engaging in an unfair process leading to the merger agreement, failing to secure and obtain the best price reasonable for Colonial shareholders, allowing preclusive deal protection devices in the merger agreement, and by engaging in conflicted actions. The complaint alleges that Colonial LP, MAA, MAA LP and OP Merger Sub aided and abetted those breaches of fiduciary duties. The complaint seeks a declaration that defendants have breached their fiduciary duties or aided and abetted such breaches and that the merger agreement is unlawful and unenforceable, an order enjoining the consummation of the mergers, direction of the Colonial trustees to exercise their fiduciary duties to obtain a transaction that is in the best interests of Colonial, rescission of the mergers in the event they are consummated, an award of costs and disbursements, including reasonable attorneys’ and experts’ fees, and other relief. On July 2, 2013, plaintiff moved for expedited fact discovery and for an expedited schedule for filing and hearing a preliminary motion to enjoin the mergers; on July 11, 2013, defendants opposed those motions and moved to stay fact discovery. On July 11, 2013, defendants also moved to dismiss the complaint for failure to state a claim upon which relief can be granted on the grounds that (1) the claims against the Colonial trustees are derivative and not direct, and plaintiff did not comply with Alabama law on serving notice of the claims on Colonial prior to filing; and (2) Alabama law does not recognize a cause of action in aiding and abetting a breach of fiduciary duty. The Court has scheduled a motions hearing for August 8, 2013.

Material U.S. Federal Income Tax Consequences of the Parent Merger (See page 122)

Colonial and MAA intend that the parent merger of Colonial with and into MAA will qualify as a reorganization within the meaning of Section 368(a) of the Code. The closing of the parent merger is conditioned on the receipt by each of MAA and Colonial of an opinion from its respective counsel to the effect that the parent merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Assuming that the parent merger qualifies as a reorganization, U.S. holders of Colonial common shares generally will not recognize gain or loss for U.S. federal income tax purposes upon the receipt of Combined Corporation common stock in exchange for Colonial common shares in connection with the parent merger, except with respect to cash received in lieu of fractional shares of Combined Corporation common stock.

For further discussion of the material U.S. federal income tax consequences of the parent merger and the ownership of common stock of the Combined Corporation, see “The Parent Merger—Material U.S. Federal Income Tax Consequences of the Parent Merger” beginning on page 122.

Holders of Colonial common shares should consult their tax advisors to determine the tax consequences to them (including the application and effect of any state, local or non-U.S. income and other tax laws) of the parent merger.

Accounting Treatment of the Mergers (See page 145)

MAA prepares its financial statements in accordance with accounting principles generally accepted in the United States, which we refer to as GAAP. The parent merger will be accounted for by applying the acquisition method. See “The Parent Merger—Accounting Treatment.”

Comparison of Rights of Shareholders of MAA and Shareholders of Colonial (See page 182)

If the parent merger is consummated, shareholders of Colonial will become shareholders of MAA. The rights of Colonial shareholders are currently governed by and subject to the provisions of the Alabama Real Estate Investment Trust Law, or the AREITL, and the declaration of trust and bylaws of Colonial. Upon consummation of the parent merger, the rights of the former Colonial shareholders who receive MAA common stock will be governed by the Tennessee Business Corporation Act, or the TBCA, and the MAA charter and MAA bylaws, rather than the declaration of trust and bylaws of Colonial.

For a summary of certain differences between the rights of MAA shareholders and Colonial shareholders, see “Comparison of Rights of Shareholders of MAA and Shareholders of Colonial” beginning on page 182.

(1)	All periods have been adjusted in accordance with ASC 205-20, Discontinued Operations.

(2)

The three months ended March 31, 2013 and 2012 do not include non-cash impairment charges. For 2012, 2011, 2010, 2009 and 2008, includes $7.0 million, $0.2 million, $0.3 million, $12.3 million, including $2.1 million presented in Discontinued Operations, and $116.9 million, including $25.5 million presented in Discontinued Operations, respectively, in non-cash impairment charges.

(4)	Subsequent to March 31, 2013, Colonial sold a commercial property with net book value of $133.4 million, resulting in a gain of $9.4 million.

(5)

Funds from Operations (FFO), as defined by the National Association of Real Estate Investment Trusts (NAREIT), means income (loss) before noncontrolling interest (determined in accordance with GAAP), excluding sales of depreciated property and impairment write-downs of depreciable real estate, plus real estate depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures. FFO is presented to assist investors in analyzing our performance. Colonial believes that FFO is useful to investors because it provides an additional indicator of our financial and operating performance. This is because, by excluding the effect of real estate depreciation and amortization, gains (or losses) from sales of properties and impairment write-downs of depreciable real estate (all of which are based on historical costs which may be of limited relevance in evaluating current performance), FFO can facilitate comparison of operating performance among equity REITs. FFO is a widely recognized measure in the company’s industry. Colonial believes that the line on our consolidated statements of operations entitled “net income (loss) available to common shareholders” is the most directly comparable GAAP measure to FFO. Historical cost accounting for real estate assets implicitly assumes that the value of real estate assets diminishes predictably over time. Since real estate values instead have historically risen or fallen with market conditions, many industry investors and analysts have considered presentation of operating results for real estate companies that use historical cost accounting to be insufficient by themselves. Thus, NAREIT created FFO as a supplemental measure of REIT operating performance that excludes historical cost depreciation, among other items, from GAAP net income. Colonial management believes that the use of FFO, combined with the required primary GAAP presentations, has been fundamentally beneficial, improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Colonial management uses FFO and FFO per share, along with other measures, to assess performance in connection with evaluating and granting incentive compensation to key employees. Colonial’s method of calculating FFO may be different from methods used by other REITs and, accordingly, may not be comparable to such other REITs. FFO should not be considered (A) as an alternative to net income (determined in accordance with GAAP), (B) as an indicator of financial performance, (C) as cash flow from operating activities (determined in accordance with GAAP) or (D) as a measure of liquidity nor is it indicative of sufficient cash flow to fund all of the company’s needs, including our ability to make distributions.

*	Non-GAAP financial measure. See Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Funds from Operations” of Colonial’s Annual Report on Form 10-K for the year ended December 31, 2012, which is incorporated herein by reference, for reconciliation.

Unaudited Comparative Per Share Information

The following table sets forth for the three months ended March 31, 2013 and the year ended December 31, 2012 selected per share information for MAA common stock on a historical and pro forma combined basis and for Colonial common shares on a historical and pro forma equivalent basis. Except for the historical information as of and for the year ended December 31, 2012, the information in the table is unaudited. You should read the table below together with the historical consolidated financial statements and related notes of MAA and Colonial contained in their respective Quarterly Reports on Form 10-Q for the three months ended March 31, 2013 and in their respective Annual Reports on Form 10-K for the year ended December 31, 2012, which are incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 201.

The Colonial pro forma equivalent per common share amounts were calculated by multiplying the MAA pro forma amounts by the exchange ratio of 0.360.

RISK FACTORS

In addition to the other information included in this joint proxy statement/prospectus, including the matters addressed in the section entitled “Cautionary Statement Concerning Forward-Looking Statements,” whether you are a MAA shareholder or Colonial shareholder, you should carefully consider the following risks before deciding how to vote. In addition, you should read and consider the risks associated with each of the businesses of MAA and Colonial because these risks will also affect the Combined Corporation. These risks can be found in the respective Annual Reports on Form 10-K for the year ended December 31, 2012 and subsequent Quarterly Reports on Form 10-Q of MAA and Colonial, each of which is filed with the SEC and incorporated by reference into this joint proxy statement/prospectus. You should also read and consider the other information in this joint proxy statement/prospectus and the other documents incorporated by reference into this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 201.

Risk Factors Relating to the Mergers

The exchange ratio is fixed and will not be adjusted in the event of any change in the share prices of either MAA or Colonial.

Upon the consummation of the parent merger, each Colonial common share (other than shares with respect to which dissenters’ rights have been properly exercised and not withdrawn under the ABCL) will be converted into the right to receive 0.360 shares of MAA common stock, with cash paid in lieu of any fractional shares. This exchange ratio was fixed in the merger agreement and will not be adjusted for changes in the market prices of either shares of MAA common stock or Colonial common shares. Changes in the market price of shares of MAA common stock prior to the parent merger will affect the market value of the merger consideration that Colonial shareholders will receive on the closing date of the parent merger. Stock price changes may result from a variety of factors (many of which are beyond the control of MAA and Colonial), including the following factors:

•

market reaction to the announcement of the mergers;

•

changes in the respective businesses, operations, assets, liabilities and prospects of MAA and Colonial;

•

changes in market assessments of the business, operations, financial position and prospects of either company or the Combined Corporation;

•

market assessments of the likelihood that the mergers will be completed;

•

interest rates, general market and economic conditions and other factors generally affecting the market prices of MAA common stock and Colonial common shares;

•

federal, state and local legislation, governmental regulation and legal developments in the businesses in which MAA and Colonial operate; and

•

other factors beyond the control of MAA and Colonial, including those described or referred to elsewhere in this “Risk Factors” section.

The market price of shares of MAA common stock at the closing of the parent merger may vary from its price on the date the merger agreement was executed, on the date of this joint proxy statement/prospectus and on the date of the special meetings of Colonial and MAA. As a result, the market value of the merger consideration represented by the exchange ratio will also vary. For example, based on the range of trading prices of shares of MAA common stock during the period after May 31, 2013, the last trading day before Colonial and MAA announced the mergers, through [—], 2013, the latest practicable date before the date of this joint proxy statement/prospectus, the exchange ratio of 0.360 represented a market value ranging from a low of $[—] to a high of $[—].

Because the parent merger will be completed after the date of the MAA and Colonial special meetings, at the time of your special meeting, you will not know the exact market value of the shares of MAA common stock that Colonial shareholders will receive upon completion of the parent merger. You should consider the following two risks:

•

If the market price of shares of MAA common stock increases between the date the merger agreement was signed or the date of the MAA and Colonial special meetings and the closing of the parent merger, Colonial shareholders will receive shares of MAA common stock that have a market value upon completion of the parent merger that is greater than the market value of such shares calculated pursuant to the exchange ratio on the date the merger agreement was signed or on the date of the special meetings, respectively.

•

If the market price of shares of MAA common stock declines between the date the merger agreement was signed or the date of the MAA and Colonial special meetings and the closing of the parent merger, Colonial shareholders will receive shares of MAA common stock that have a market value upon completion of the parent merger that is less than the market value of such shares calculated pursuant to the exchange ratio on the date the merger agreement was signed or on the date of the special meetings, respectively.

Therefore, while the number of shares of MAA common stock to be issued per share of Colonial common shares is fixed, (1) MAA shareholders cannot be sure of the market value of the consideration that will be paid to Colonial shareholders upon completion of the parent merger and (2) Colonial shareholders cannot be sure of the market value of the consideration they will receive upon completion of the parent merger.

In order for the parent merger to be completed, both MAA shareholders and Colonial shareholders must approve the parent merger and the other transactions contemplated by the merger agreement and holders of limited partnership interests of MAA LP must approve the partnership merger and the amendment and restatement of the limited partnership agreement of MAA LLP. Approval of the parent merger requires (i) the affirmative vote of a majority of the shares of MAA common stock outstanding and entitled to vote on the proposal; and (ii) the affirmative vote of a majority of the Colonial common shares outstanding as of the record date for the Colonial special meeting. Approval of the partnership merger and the amendment and restatement of the limited partnership agreement of MAA requires the approval of holders of at least 66 2/3rds of the outstanding limited partnership interests of MAA LP, excluding for purposes of the approval all limited partnership interests held by MAA.

MAA and Colonial shareholders will be diluted by the parent merger.

The parent merger will dilute the ownership position of the MAA shareholders and result in Colonial shareholders having an ownership stake in the Combined Corporation that is smaller than their current stake in Colonial. Upon completion of the parent merger, we estimate that continuing MAA equity holders will own approximately 56% of the issued and outstanding shares of Combined Corporation common stock, assuming the conversion of all limited partnership units of MAA LP held by existing limited partners of MAA LP to shares of Combined Corporation common stock, and former Colonial equity holders will own approximately 44% of the issued and outstanding shares of common stock of the Combined Corporation, assuming the conversion to shares of Combined Corporation common stock of all limited partnership units issued by MAA LP to former limited partners of Colonial LP. Consequently, MAA shareholders and Colonial shareholders, as a general matter, will have less influence over the management and policies of the Combined Corporation after the effective time of the parent merger than each currently exercise over the management and policies of MAA and Colonial, as applicable.

If the mergers do not occur, one of the companies may incur payment obligations to the other.

If the merger agreement is terminated under certain circumstances, MAA or Colonial may be obligated to pay the other party a termination fee of $75 million and/or up to $10 million in expense reimbursement. See “The Merger Agreement—Termination of the Merger Agreement—Termination Fee and Expenses Payable by Colonial to MAA” beginning on page 165 and “The Merger Agreement—Termination of the Merger Agreement—Termination Fee and Expenses Payable by MAA to Colonial” beginning on page 166.

Failure to complete the mergers could negatively affect the stock prices and the future business and financial results of both MAA and Colonial.

If the mergers are not completed, the ongoing businesses of MAA and Colonial could be adversely affected and each of MAA and Colonial will be subject to a variety of risks associated with the failure to complete the mergers, including the following:

•

MAA or Colonial being required, under certain circumstances, to pay to the other party a termination fee of $75 million and/or up to $10 million in expense reimbursement;

•

having to pay certain costs relating to the proposed mergers, such as legal, accounting, financial advisor, filing, printing and mailing fees; and

•

diversion of management focus and resources from operational matters and other strategic opportunities while working to implement the mergers.

If the mergers are not completed, these risks could materially affect the business, financial results and stock prices of both MAA and Colonial.

The pendency of the mergers could adversely affect the business and operations of MAA and Colonial.

Prior to the effective time of the mergers, some tenants or vendors of each of MAA and Colonial may delay or defer decisions, which could negatively affect the revenues, earnings, cash flows and expenses of MAA and Colonial, regardless of whether the mergers are completed. Similarly, current and prospective employees of MAA and Colonial may experience uncertainty about their future roles with the Combined Corporation following the mergers, which may materially adversely affect the ability of each of MAA and Colonial to attract and retain key personnel during the pendency of the mergers. In addition, due to operating restrictions in the merger agreement, each of MAA and Colonial may be unable, during the pendency of the mergers, to pursue strategic transactions, undertake significant capital projects, undertake certain significant financing transactions and otherwise pursue other actions, even if such actions would prove beneficial.

The merger agreement contains provisions that could discourage a potential competing acquirer of either MAA or Colonial or could result in any competing acquisition proposal being at a lower price than it might otherwise be.

The merger agreement contains provisions that, subject to limited exceptions, restrict the ability of each of MAA and Colonial to initiate, solicit, knowingly encourage or knowingly facilitate any third-party proposals to acquire all or a significant part of MAA or Colonial, respectively. With respect to any bona fide third-party Acquisition Proposal, either MAA or Colonial, as applicable, generally has an opportunity to offer to modify the terms of the merger agreement in response to such proposal before the MAA Board or the Colonial Board, as the case may be, may withdraw or modify its recommendation to their respective shareholders in response to such Acquisition Proposal. Upon termination of the merger agreement in certain circumstances, one of the parties may be required to pay a substantial termination fee and/or expense reimbursement to the other party. See “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions” beginning on page 156, “The Merger Agreement—Termination of the Merger Agreement—Termination Fee and Expenses Payable by Colonial to MAA” beginning on page 165, and “The Merger Agreement—Termination of the Merger Agreement—Termination Fee and Expenses Payable by MAA to Colonial” beginning on page 166.

These provisions could discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of MAA or Colonial from considering or proposing a competing acquisition, even if the potential competing acquirer was prepared to pay consideration with a higher per share cash value than that market value proposed to be received or realized in the mergers, or might result in a potential competing acquirer proposing to pay a lower price than it might otherwise have proposed to pay because of the added expense of the termination fee and expense reimbursement that may become payable in certain circumstances under the merger agreement.

If the mergers are not consummated by December 31, 2013, either MAA or Colonial may terminate the merger agreement.

Either MAA or Colonial may terminate the merger agreement if the mergers have not been consummated by December 31, 2013. However, this termination right will not be available to a party if that party failed to fulfill its obligations under the merger agreement and that failure was the cause of, or resulted in, the failure to consummate the mergers. See “The Merger Agreement—Termination of the Merger Agreement” beginning on page 164.

If the parent merger does not qualify as a tax-free reorganization, Colonial or MAA shareholders may recognize a taxable gain.

The parent merger is intended to qualify as a tax-free reorganization within the meaning of Section 368(a) of the Code. As a result, Colonial shareholders that are U.S. holders (as defined below) are not expected to recognize gain or loss as a result of the parent merger (except with respect to the receipt of cash in lieu of fractional shares of Combined Corporation common stock). The closing of the parent merger is conditioned on the receipt by each of MAA and Colonial of an opinion from its respective counsel to the effect that the parent merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. However, these legal opinions will not be binding on the Internal Revenue Service, or the IRS, or on the courts. If for any reason the parent merger does not qualify as a tax-free reorganization within the meaning of Section 368(a) of the Code, then each Colonial shareholder generally would recognize gain or loss, for U.S. federal income tax purposes, equal to the difference between the sum of the fair market value of the Combined Corporation common stock and cash in lieu of fractional shares of Combined Corporation common stock received by the shareholder in the parent merger and the shareholder’s adjusted tax basis in the Colonial common shares exchanged therefor. Moreover, under the “investment company” rules under Section 368 of the Code, if both MAA and Colonial are “investment companies” under such rules, the failure of either Colonial or MAA to qualify as a REIT could cause the parent merger to be taxable to Colonial or MAA, respectively, and its shareholders. See “The Parent Merger—Material U.S. Federal Income Tax Consequences of the Parent Merger” on page 122.

Some of the directors and executive officers of MAA and trustees and executive officers of Colonial have arrangements that provide them with interests in the mergers that are different from, or in addition to, those of the shareholders of MAA or the shareholders of Colonial generally. These interests include, among other things, the continued service as a director or an executive officer of the Combined Corporation, or, in the alternative, a sizeable severance payment if terminated upon, or following, consummation of the mergers and the ownership of limited partnership interests of either MAA LP or Colonial LP, as applicable. These interests, among other things, may influence or may have influenced the directors and executive officers of MAA and trustees and executive officers of Colonial to support or approve the mergers. See “The Parent Merger—Interests of MAA’s Directors and Executive Officers in the Mergers” beginning on page 115 and “The Parent Merger—Interests of Colonial’s Trustees and Executive Officers in the Mergers” beginning on page 116.

Risk Factors Relating to the Combined Corporation Following the Mergers

Risks Related to the Combined Corporation’s Operations

The Combined Corporation expects to incur substantial expenses related to the mergers.

The Combined Corporation expects to incur substantial expenses in connection with completing the mergers and integrating the business, operations, networks, systems, technologies, policies and procedures of the two companies. There are a large number of systems that must be integrated, including property management, revenue management, resident payment, credit screening, lease administration, website content management, purchasing, accounting, payroll, fixed assets and financial reporting. Although MAA and Colonial have assumed that a certain level of transaction and integration expenses would be incurred, there are a number of factors beyond their control that could affect the total amount or the timing of their integration expenses. Many of the expenses that will be incurred, by their nature, are difficult to estimate accurately at the present time. As a result, the transaction and integration expenses associated with the mergers could, particularly in the near term, exceed the savings that the Combined Corporation expects to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the integration of the businesses following the completion of the mergers.

Following the mergers, the Combined Corporation may be unable to integrate the businesses of MAA and Colonial successfully and realize the anticipated synergies and other benefits of the mergers or do so within the anticipated timeframe.

The mergers involve the combination of two companies that currently operate as independent public companies. MAA and Colonial estimate that the transaction will generate approximately $25 million of annual gross savings in general and administrative expenses. The Combined Corporation is expected to benefit from the elimination of duplicative costs associated with supporting a public company platform and the leveraging of state of the art technology and systems. These savings are expected to be realized upon full integration, which is expected to occur over the 18-month period following the closing of the mergers. However, the Combined Corporation will be required to devote significant management attention and resources to integrating the business practices and operations of MAA and Colonial. Potential difficulties the Combined Corporation may encounter in the integration process include the following:

•

the inability to successfully combine the businesses of MAA and Colonial in a manner that permits the Combined Corporation to achieve the cost savings anticipated to result from the mergers, which would result in the anticipated benefits of the mergers not being realized in the timeframe currently anticipated or at all;

•

the complexities associated with managing the combined businesses out of several different locations and integrating personnel from the two companies;

•

the additional complexities of combining two companies with different histories, cultures, regulatory restrictions, markets and customer bases;

•

potential unknown liabilities and unforeseen increased expenses, delays or regulatory conditions associated with the mergers; and

•

performance shortfalls as a result of the diversion of management’s attention caused by completing the mergers and integrating the companies’ operations.

For all these reasons, you should be aware that it is possible that the integration process could result in the distraction of the Combined Corporation’s management, the disruption of the Combined Corporation’s ongoing business or inconsistencies in the Combined Corporation’s operations, services, standards, controls, procedures and policies, any of which could adversely affect the ability of the Combined Corporation to maintain relationships with tenants, vendors and employees or to achieve the anticipated benefits of the mergers, or could otherwise adversely affect the business and financial results of the Combined Corporation.

Following the mergers, the Combined Corporation may be unable to retain key employees.

The success of the Combined Corporation after the mergers will depend in part upon its ability to retain key MAA and Colonial employees. Key employees may depart either before or after the mergers because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the Combined Corporation following the mergers. Accordingly, no assurance can be given that MAA, Colonial or, following the mergers, the Combined Corporation will be able to retain key employees to the same extent as in the past.

The mergers will result in changes to the board of directors and management of the Combined Corporation that may affect the strategy of the Combined Corporation as compared to that of MAA and Colonial independently.

If the parties complete the mergers, the composition of the board of directors of the Combined Corporation and management team will change from the respective boards and management teams of MAA and Colonial. The board of directors of the Combined Corporation will consist of twelve members, with all seven directors from the current MAA Board and five directors from the current Colonial Board constituting the members of the Combined Corporation’s board of directors. Alan B. Graf, Jr. and Ralph Horn, Co-Lead Independent Directors for MAA, will serve as Co-Lead Independent Directors for the Combined Corporation. H. Eric Bolton, Jr., MAA’s Chief Executive Officer and Chairman of the Board of Directors, will serve as Chief Executive Officer and Chairman of the Board of Directors of the Combined Corporation. Albert M. Campbell, III, MAA’s Chief Financial Officer, will serve as Chief Financial Officer of the Combined Corporation, and Thomas L. Grimes, Jr., MAA’s Chief Operating Officer, will serve as the Chief Operating Officer of the Combined Corporation. This new composition of the board of directors and the management team of the Combined Corporation may affect the business strategy and operating decisions of the Combined Corporation upon the completion of the mergers.

The future results of the Combined Corporation will suffer if the Combined Corporation does not effectively manage its expanded operations following the mergers.

Following the mergers, the Combined Corporation expects to continue to expand its operations through additional acquisitions of properties, some of which may involve complex challenges. The future success of the Combined Corporation will depend, in part, upon the ability of the Combined Corporation to manage its expansion opportunities, which may pose substantial challenges for the Combined Corporation to integrate new operations into its existing business in an efficient and timely manner, and upon its ability to successfully monitor its operations, costs, regulatory compliance and service quality, and to maintain other necessary internal controls. There is no assurance that the Combined Corporation’s expansion or acquisition opportunities will be successful, or that the Combined Corporation will realize its expected operating efficiencies, cost savings, revenue enhancements, synergies or other benefits.

Risks Related to an Investment in the Combined Corporation’s Common Stock

The market price of shares of the common stock of the Combined Corporation may be affected by factors different from those affecting the price of shares of MAA common stock or Colonial common shares before the mergers.

Upon completion of the parent merger, we estimate that continuing MAA equity holders will own approximately 56% of the issued and outstanding shares of Combined Corporation common stock, assuming the conversion of all limited partnership units of MAA LP held by existing limited partners of MAA LP to shares of Combined Corporation common stock, and former Colonial equity holders will own approximately 44% of the issued and outstanding shares of common stock of the Combined Corporation, assuming the conversion to shares of Combined Corporation common stock of all limited partnership units issued by MAA LP to former limited partners of Colonial LP. The results of operations of the Combined Corporation, as well as the market price of the common stock of the Combined Corporation, after the parent merger may be affected by other factors in

addition to those currently affecting MAA’s or Colonial’s results of operations and the market prices of MAA common stock and Colonial common shares. These factors include:

•

a greater number of shares of the Combined Corporation outstanding as compared to the number of currently outstanding shares of MAA;

•

different shareholders;

•

different markets; and

•

different assets and capitalizations

Accordingly, the historical market prices and financial results of MAA and Colonial may not be indicative of these matters for the Combined Corporation after the parent merger. For a discussion of the businesses of MAA and Colonial and certain risks to consider in connection with investing in those businesses, see the documents incorporated by reference by MAA and Colonial into this joint proxy statement/prospectus referred to under “Where You Can Find More Information.”

The market price of the Combined Corporation’s common stock may decline as a result of the mergers.

The market price of the Combined Corporation’s common stock may decline as a result of the mergers if the Combined Corporation does not achieve the perceived benefits of the mergers as rapidly or to the extent anticipated by financial or industry analysts, or the effect of the mergers on the Combined Corporation’s financial results is not consistent with the expectations of financial or industry analysts.

In addition, upon consummation of the parent merger, MAA shareholders and Colonial shareholders will own interests in a Combined Corporation operating an expanded business with a different mix of properties, risks and liabilities. Current shareholders of MAA and Colonial may not wish to continue to invest in the Combined Corporation, or for other reasons may wish to dispose of some or all of their shares of the Combined Corporation’s common stock. If, following the effective time of the parent merger, large amounts of the Combined Corporation’s common stock are sold, the price of the Combined Corporation’s common stock could decline.

After the parent merger is completed, Colonial shareholders who receive shares of the Combined Corporation common stock in the parent merger will have different rights that may be less favorable than their current rights as Colonial shareholders.

After the closing of the parent merger, Colonial shareholders who receive shares of the Combined Corporation common stock in the parent merger will have different rights than they currently have as Colonial shareholders. For a detailed discussion of the significant differences between the current rights as a shareholder of Colonial and the rights as a shareholder of the Combined Corporation following the parent merger, see “Comparison of Rights of Shareholders of MAA and Shareholders of Colonial” beginning on page 182.

The Combined Corporation cannot assure you that it will be able to continue paying dividends at or above the rate currently paid by MAA and Colonial.

The shareholders of the Combined Corporation may not receive dividends at the same rate they received dividends as shareholders of MAA and Colonial following the parent merger for various reasons, including the following:

•

the Combined Corporation may not have enough cash to pay such dividends due to changes in the Combined Corporation’s cash requirements, capital spending plans, cash flow or financial position;

•

decisions on whether, when and in which amounts to make any future distributions will remain at all times entirely at the discretion of the Combined Corporation’s board of directors, which reserves the right to change MAA’s current dividend practices at any time and for any reason;

•

the Combined Corporation may desire to retain cash to maintain or improve its credit ratings; and

•

the amount of dividends that the Combined Corporation’s subsidiaries may distribute to the Combined Corporation may be subject to restrictions imposed by state law, restrictions that may be imposed by state regulators, and restrictions imposed by the terms of any current or future indebtedness that these subsidiaries may incur.

Shareholders of the Combined Corporation will have no contractual or other legal right to dividends that have not been declared by the Combined Corporation’s board of directors.

In connection with the announcement of the merger agreement, one lawsuit has been filed and is pending as of July 18, 2013, seeking, among other things, to enjoin the mergers, and an adverse judgment in this lawsuit may prevent the mergers from being effective or from becoming effective within the expected timeframe.

On June 19, 2013, a putative class action and derivative lawsuit was filed in the Circuit Court for Jefferson County, Alabama against and purportedly on behalf of Colonial captioned Williams v. Colonial Properties Trust, et al. The complaint names as defendants Colonial, the members of the Colonial Board, Colonial, LP, MAA, MAA LP and OP Merger Sub and alleges that the trustees of Colonial breached their fiduciary duties by engaging in an unfair process leading to the merger agreement, failing to secure and obtain the best price reasonable for Colonial shareholders, allowing preclusive deal protection devices in the merger agreement, and by engaging in conflicted actions. The complaint alleges that Colonial LP, MAA, MAA LP and OP Merger Sub aided and abetted those breaches of fiduciary duties. The complaint seeks a declaration that the defendants have breached their fiduciary duties or aided and abetted such breaches and that the merger agreement is unlawful and unenforceable, an order enjoining the consummation of the mergers, direction of the Colonial trustees to exercise their fiduciary duties to obtain a transaction that is in the best interests of Colonial, rescission of the mergers in the event they are consummated, an award of costs and disbursements, including reasonable attorneys’ and experts’ fees, and other relief. On July 2, 2013, plaintiff moved for expedited fact discovery and for an expedited schedule for filing and hearing a preliminary motion to enjoin the mergers; on July 11, 2013, defendants opposed those motions and moved to stay fact discovery. On July 11, 2013, defendants also moved to dismiss the complaint for failure to state a claim upon which relief can be granted on the grounds that: (1) the claims against the Colonial trustees are derivative and not direct, and plaintiff did not comply with Alabama law on serving notice of the claims on Colonial prior to filing; and (2) Alabama law does not recognize a cause of action in aiding and abetting a breach of fiduciary duty. The Court has scheduled a motions hearing for August 8, 2013. MAA or Colonial may also be the target of similar litigation in the future.

While Colonial and MAA management believe that the allegations in the complaint are without merit and intend to defend vigorously against these allegations, Colonial and MAA cannot assure you as to the outcome of this, or any similar future lawsuits, including the costs associated with defending this claim or any other liabilities that may be incurred in connection with the litigation or settlement of this claim. Neither Colonial nor MAA is able to reliably estimate the likelihood or amount of potential loss. If the plaintiff is successful in obtaining an injunction prohibiting the parties from completing the mergers on the agreed-upon terms, such an injunction may prevent the completion of the mergers in the expected time frame, or may prevent them from being completed altogether. Whether the plaintiff’s claims are successful, this type of litigation is often expensive and diverts management’s attention and resources, which could adversely affect the operation of the businesses of MAA and Colonial. For more information about litigation related to the mergers, see “The Parent Merger—Litigation Relating to the Mergers” beginning on page 146.

Counterparties to certain significant agreements with MAA or Colonial may exercise contractual rights under such agreements in connection with the mergers.

MAA and Colonial are each party to certain agreements that give the counterparty certain rights following a “change in control,” including in some cases the right to terminate the agreement. Under some such agreements, the mergers will constitute a change in control and therefore the counterparty may exercise certain rights under

the agreement upon the closing of the mergers. Certain MAA and Colonial joint ventures, management and service contracts, and debt obligations have agreements subject to such provisions. Any such counterparty may request modifications of their respective agreements as a condition to granting a waiver or consent under their agreement. There can be no assurances that such counterparties will not exercise their rights under these agreements, including termination rights where available, or that the exercise of any such rights under, or modification of, these agreements will not adversely affect the business or operations of the Combined Corporation.

The historical and unaudited pro forma combined condensed financial information included elsewhere in this joint proxy statement/prospectus may not be representative of the Combined Corporation’s results after the mergers, and accordingly, you have limited financial information on which to evaluate the Combined Corporation.

The unaudited pro forma combined condensed financial information included elsewhere in this joint proxy statement/prospectus has been presented for informational purposes only and is not necessarily indicative of the financial position or results of operations that actually would have occurred had the mergers been completed as of the date indicated, nor is it indicative of the future operating results or financial position of the Combined Corporation. The unaudited pro forma combined condensed financial information does not reflect future events that may occur after the mergers, including the costs related to the planned integration of the two companies and any future nonrecurring charges resulting from the mergers, and does not consider potential impacts of current market conditions on revenues or expense efficiencies. The unaudited pro forma combined condensed financial information presented elsewhere in this joint proxy statement/prospectus is based in part on certain assumptions regarding the mergers that MAA and Colonial believe are reasonable under the circumstances. MAA and Colonial cannot assure you that the assumptions will prove to be accurate over time.

The Combined Corporation will have a significant amount of indebtedness and may need to incur more in the future.

The Combined Corporation will have substantial indebtedness following completion of the parent merger. For example, as of June 30, 2013, the Combined Corporation would have had an estimated fixed charge coverage ratio of 1.7x and an estimated debt as a percentage of total market capitalization of 40.5% (by comparison, as of that date, the standalone figures for MAA were 2.3x and 35.6%, respectively, and for Colonial were 1.1x and 41.7%, respectively). In addition, in connection with executing the Combined Corporation’s business strategies following the mergers, the Combined Corporation expects to continue to evaluate the possibility of acquiring additional properties and making strategic investments, and the Combined Corporation may elect to finance these endeavors by incurring additional indebtedness. The amount of such indebtedness could have material adverse consequences for the Combined Corporation, including:

•

reducing the Combined Corporation’s credit ratings and thereby raising its borrowing costs;

•

hindering the Combined Corporation’s ability to adjust to changing market, industry or economic conditions;

•

limiting the Combined Corporation’s ability to access the capital markets to refinance maturing debt or to fund acquisitions or emerging businesses;

•

limiting the amount of free cash flow available for future operations, acquisitions, dividends, stock repurchases or other uses;

•

making the Combined Corporation more vulnerable to economic or industry downturns, including interest rate increases; and

•

placing the Combined Corporation at a competitive disadvantage compared to less leveraged competitors.

Moreover, to respond to competitive challenges, the Combined Corporation may be required to raise substantial additional capital to execute its business strategy. The Combined Corporation’s ability to arrange additional financing will depend on, among other factors, the Combined Corporation’s financial position and performance, as well as prevailing market conditions and other factors beyond the Combined Corporation’s control. If the Combined Corporation is able to obtain additional financing, the Combined Corporation’s credit ratings could be further adversely affected, which could further raise the Combined Corporation’s borrowing costs and further limit its future access to capital and its ability to satisfy its obligations under its indebtedness.

The Combined Corporation may incur adverse tax consequences if MAA or Colonial has failed or fails to qualify as a REIT for U.S. federal income tax purposes.

Each of MAA and Colonial has operated in a manner that it believes has allowed it to qualify as a REIT for U.S. federal income tax purposes under the Code, and each intend to continue to do so through the time of the parent merger, and the Combined Corporation intends to continue operating in such a manner following the parent merger. None of MAA, Colonial or the Combined Corporation has requested or plans to request a ruling from the IRS that it qualifies as a REIT. Qualification as a REIT involves the application of highly technical and complex Code provisions for which there are only limited judicial and administrative interpretations. The complexity of these provisions and of the applicable Treasury Regulations that have been promulgated under the Code is greater in the case of a REIT that holds its assets through a partnership (such as both Colonial and MAA do, and as the Combined Corporation will, following the parent merger). The determination of various factual matters and circumstances not entirely within the control of MAA, Colonial or the Combined Corporation, as the case may be, may affect any such company’s ability to qualify as a REIT. In order to qualify as a REIT, each of MAA, Colonial and the Combined Corporation must satisfy a number of requirements, including requirements regarding the ownership of its stock and the composition of its gross income and assets. Also, a REIT must make distributions to shareholders aggregating annually at least 90% of its net taxable income, excluding any net capital gains.

If any of MAA, Colonial or the Combined Corporation loses its REIT status, or is determined to have lost its REIT status in a prior year, it will face serious tax consequences that would substantially reduce its cash available for distribution, including cash available to pay dividends to its shareholders, because:

•

such company would be subject to U.S. federal income tax on its net income at regular corporate rates for the years it did not qualify for taxation as a REIT (and, for such years, would not be allowed a deduction for dividends paid to shareholders in computing its taxable income);

•

such company could be subject to the federal alternative minimum tax and possibly increased state and local taxes for such periods;

•

unless such company is entitled to relief under applicable statutory provisions, neither it nor any “successor” company could elect to be taxed as a REIT until the fifth taxable year following the year during which it was disqualified; and

•

for the ten years following re-election of REIT status, upon a taxable disposition of an asset owned as of such re-election, such company would be subject to corporate level tax with respect to any built-in gain inherent in such asset at the time of re-election.

The Combined Corporation will inherit any liability with respect to unpaid taxes of MAA or Colonial for any periods prior to the parent merger. In addition, as described above, if Colonial failed to qualify as a REIT as of the parent merger but the Combined Corporation nonetheless qualified as a REIT, in the event of a taxable disposition of a former Colonial asset during the ten years following the parent merger the Combined Corporation would be subject to corporate tax with respect to any built-in gain inherent in such asset as of the parent merger. In addition, under the “investment company” rules under Section 368 of the Code, if both MAA and Colonial are “investment companies” under such rules, the failure of either Colonial or MAA to qualify as a REIT could cause the parent merger to be taxable to Colonial or MAA, respectively, and its shareholders. As a result of all these factors, MAA’s, Colonial’s or the Combined Corporation’s failure to qualify as a REIT could

impair the Combined Corporation’s ability to expand its business and raise capital, and would materially adversely affect the value of its stock. In addition, for years in which the Combined Corporation does not qualify as a REIT, it will not otherwise be required to make distributions to shareholders.

In certain circumstances, even if the Combined Corporation qualifies as a REIT, it and its subsidiaries may be subject to certain U.S. federal, state, and other taxes, which would reduce the Combined Corporation’s cash available for distribution to its shareholders.

Even if each of MAA, Colonial and the Combined Corporation has, as the case may be, qualified and continues to qualify as a REIT, the Combined Corporation may be subject to U.S. federal, state, or other taxes. For example, net income from the sale of properties that are “dealer” properties sold by a REIT (a “prohibited transaction” under the Code) will be subject to a 100% tax. In addition, the Combined Corporation may not be able to make sufficient distributions to avoid income and excise taxes applicable to REITs. Alternatively, the Combined Corporation may decide to retain income it earns from the sale or other disposition of its property and pay income tax directly on such income. In that event, the Combined Corporation’s shareholders would be treated as if they earned that income and paid the tax on it directly. However, shareholders that are tax-exempt, such as charities or qualified pension plans, might not have any benefit from their deemed payment of such tax liability. The Combined Corporation and its subsidiaries may also be subject to U.S. federal taxes other than U.S. federal income taxes, as well as state and local taxes (such as state and local income and property taxes), either directly or at the level of its operating partnership, or at the level of the other companies through which the Combined Corporation indirectly owns its assets. Any U.S. federal or state taxes the Combined Corporation (or any of its subsidiaries) pays will reduce cash available for distribution by the Combined Corporation to shareholders. See section “The Parent Merger—Material U.S. Federal Income Tax Consequences of the Parent Merger” beginning on page 122.

MAA and Colonial face other risks.

The foregoing risks are not exhaustive, and you should be aware that, following the mergers, the Combined Corporation will face various other risks, including those discussed in reports filed by MAA and Colonial with the SEC. See “Where You Can Find More Information” beginning on page 201.

THE MAA SPECIAL MEETING

Date, Time and Place

The MAA special meeting will be held at MAA corporate headquarters, 6584 Poplar Avenue, Memphis, Tennessee 38138, on [—], 2013, at [—] a.m., Central Daylight Time.

Purpose of the MAA Special Meeting

At the MAA special meeting, MAA shareholders will be asked to consider and vote upon the following matters:

•

a proposal to approve the merger agreement, the merger of Colonial with and into MAA, with MAA continuing as the surviving corporation, and the other transaction contemplated by the merger agreement, including the issuance of MAA common stock to Colonial shareholders in connection with the parent merger, which we refer to collectively as the MAA merger proposal;

•

a proposal to approve the MAA 2013 Stock Incentive Plan; and

•

Recommendation of the MAA Board

After careful consideration, the MAA Board has unanimously determined and declared that the merger agreement, the parent merger and the other transactions contemplated by the merger agreement (including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger) are advisable and in the best interests of MAA and its shareholders and has unanimously adopted and approved the merger agreement, the parent merger and the other transactions contemplated by the merger agreement. Certain factors considered by the MAA Board in reaching its decision to adopt and approve the parent merger can be found in the section of this joint proxy/statement/prospectus entitled “The Parent Merger—Recommendation of the MAA Board and Its Reasons for the Parent Merger” beginning on page 87.

The MAA Board unanimously recommends that MAA shareholders vote FOR the MAA merger proposal, FOR the proposal to approve the MAA 2013 Stock Incentive Plan and FOR the proposal to adjourn the MAA special meeting, if necessary or appropriate in the view of the MAA Board, to solicit additional proxies in favor of the proposals if there are not sufficient votes at the time of such adjournment to approve such proposals.

Approval of the merger agreement is subject to a vote by MAA’s shareholders separate from the vote on approval of the MAA 2013 Stock Incentive Plan. Approval of the MAA 2013 Stock Incentive Plan is not a condition to completion of the mergers.

MAA Record Date; Who Can Vote at the MAA Special Meeting

Only MAA shareholders of record at the close of business on the record date, [—], are entitled to receive notice of the MAA special meeting and to vote the shares of MAA common stock that they held on the record date at the MAA special meeting, or any postponement or adjournment of the MAA special meeting. The only class of stock that can be voted at the MAA special meeting is MAA common stock. Each share of MAA common stock is entitled to one vote on all matters that come before the MAA special meeting.

On the record date, there were approximately [—] shares of MAA common stock outstanding and entitled to vote at the MAA special meeting.

A list of MAA shareholders entitled to vote at the MAA special meeting will be open for examination by any MAA shareholder, for any purpose germane to the MAA special meeting, during ordinary business hours,

beginning two (2) days after notice of the MAA special meeting is given through the time of the MAA special meeting and place of the MAA special meeting at MAA’s principal executive offices at 6587 Poplar Avenue, Memphis, Tennessee 38138.

Quorum

A quorum of shareholders is necessary to hold a valid special meeting. The presence, in person or by proxy, of holders of a majority of the shares of MAA common stock outstanding on the MAA record date will constitute a quorum. On the record date, there were [—] shares of MAA common stock outstanding and entitled to vote. Thus, [—] shares of MAA common stock must be represented by shareholders present at the MAA special meeting or by proxy to have a quorum for the MAA special meeting.

Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the Chairman of the MAA special meeting or a majority of the votes present at the MAA special meeting may adjourn the MAA special meeting to another date.

Vote Required for Approval

Approval of the MAA merger proposal requires the affirmative vote of holders of a majority of the outstanding shares of MAA common stock.

Approval of the adjournment of the MAA special meeting requires the votes cast “FOR” the proposal exceed the votes cast “AGAINST” the proposal.

Abstentions and Broker Non-Votes

If you are a MAA shareholder and fail to vote, fail to instruct your broker, bank or nominee to vote, or abstain from voting:

•

with respect to the MAA merger proposal, it will have the same effect as a vote “AGAINST” the MAA merger proposal;

•

with respect to the adjournment proposal, it will have no effect on the outcome of the vote for this proposal.

Voting by MAA Directors and Executive Officers

Manner of Submitting Proxy

A proxy card is enclosed for use by MAA shareholders. MAA requests that MAA shareholders sign the accompanying proxy card and return it promptly in the enclosed postage-paid envelope. MAA shareholders may also vote their shares by telephone or through the Internet. Information and applicable deadlines for voting proxies by telephone or through the Internet are set forth on the enclosed proxy card. When the accompanying proxy is returned properly executed, the shares of MAA common stock represented by it will be voted at the MAA special meeting or any adjournment or postponement thereof in accordance with the instructions contained in the proxy card.

If a proxy card is signed and returned without an indication as to how the shares of MAA common stock represented by the proxy are to be voted with regard to a particular proposal, the MAA common stock represented by the proxy will be voted “FOR” each such proposal. As of the date of this joint proxy statement/prospectus, MAA has no knowledge of any business that will be presented for consideration at the MAA special meeting and which would be required to be set forth in this joint proxy statement/prospectus other than the matters set forth in the accompanying Notice of Special Meeting of Shareholders of MAA. In accordance with the MAA bylaws and Tennessee law, business transacted at the MAA special meeting will be limited to those matters set forth in such notice. Nonetheless, if any other matter is properly presented at the MAA special meeting for consideration, it is intended that the persons named in the enclosed proxy and acting thereunder will vote in accordance with their discretion on such matter.

Your vote is important. Accordingly, please sign and return the enclosed proxy card whether or not you plan to attend the MAA special meeting in person.

Shares held in “Street Name”

If a MAA shareholder holds shares of MAA common stock in a stock brokerage account or if its shares are held by a bank or nominee (that is, in “street name”), such shareholder must provide the record holder of its shares with instructions on how to vote its shares of MAA common stock. MAA shareholders should follow the voting instructions provided by their broker, bank or nominee. Please note that MAA shareholders may not vote shares of MAA common stock held in street name by returning a proxy card directly to MAA or by voting in person at the MAA special meeting unless they provide a “legal proxy,” which MAA shareholders must obtain from their broker, bank or nominee. Further, brokers, banks or nominees who hold shares of MAA common stock on behalf of their customers may not give a proxy to MAA to vote those shares without specific instructions from their customers.

If a MAA shareholder does not instruct its broker, bank or nominee to vote, then the broker, bank or nominee may not vote those shares, and it will have the effects described above under “—Abstentions and Broker Non-Votes.”

Shares held in the MAA Employee Stock Ownership Plan

If MAA shareholders hold shares of MAA common stock in an account under the MAA Employee Stock Ownership Plan, such shareholders have the right to vote the shares in their account. To do this, the MAA shareholder must sign and timely return the proxy card received with this joint proxy statement/prospectus, or grant the shareholder’s proxy by telephone or over the Internet by following the instructions on the proxy card.

Revocation of Proxies or Voting Instructions

MAA shareholders of record may change their vote or revoke their proxy at any time before the final vote at the MAA special meeting by:

submitting another properly completed proxy card bearing in time to be received before the MAA special meeting or by submitting a later dated proxy by telephone or over the Internet in which case the later-submitted proxy will be recorded and the earlier proxy revoked;

submitting written notice that the MAA shareholder is revoking the proxy to MAA’s Corporate Secretary, 6584 Poplar Avenue, Memphis, Tennessee 38138 in time to be received before the MAA special meeting; or

voting in person at the MAA special meeting.

Attending the MAA special meeting without voting will not, by itself, revoke a MAA shareholder’s proxy.

If a MAA shareholder’s common shares are held by its broker or bank as nominee or agent, the shareholder should follow the instructions provided by the broker or bank.

Tabulation of Votes

MAA will appoint an inspector of election for the MAA special meeting to tabulate affirmative and negative votes, broker non-votes and abstentions.

Solicitation of Proxies; Payment of Solicitation Expenses

The cost of proxy solicitation for the MAA special meeting will be borne by MAA. In addition to the use of the mail, proxies may be solicited by officers, directors and regular employees of MAA, without additional remuneration, in person, by telephone or any other electronic means of communication deemed appropriate. MAA will also request brokerage firms, nominees, custodians and fiduciaries to forward proxy materials to the beneficial owners of shares held of record on the record date and will provide customary reimbursement to such firms for the cost of forwarding these materials. MAA has retained D.F. King to assist in its solicitation of proxies and has agreed to pay them a fee of approximately $20,000 for these services, plus reimbursement for reasonable out-of-pocket expenses and expenses, and to indemnify D.F. King against certain losses, costs and expenses.

Adjournment

In addition to the other proposals being considered at the MAA special meeting, MAA shareholders are also being asked to approve a proposal that will give the MAA Board authority to adjourn the MAA special meeting, if necessary or appropriate in the view of the MAA Board, to solicit additional proxies in favor of the other proposals if there are not sufficient votes at the time of such adjournment to approve such proposals. If this proposal is approved, the MAA special meeting could be successively adjourned to any date. In addition, the MAA Board could postpone the MAA special meeting before it commences, whether for the purpose of soliciting additional proxies or for other reasons. If the MAA special meeting is adjourned for the purpose of soliciting additional proxies, shareholders who have already submitted their proxies will be able to revoke them at any time prior to their use.

If a quorum does not exist, the chairman of the MAA special meeting or the holders of a majority of the shares of MAA common stock present at the MAA special meeting, in person or by proxy, may adjourn the MAA special meeting to another place, date or time. If a quorum exists, but there are not enough affirmative votes to approve any other proposal, the MAA special meeting may be adjourned if the votes cast, in person or by proxy, at the MAA special meeting in favor of the adjournment proposal exceed the votes cast, in person or by proxy, against the adjournment proposal.

Assistance

If you need assistance in completing your proxy card or have questions regarding the various voting options with respect to the MAA special meeting, please contact MAA’s proxy solicitor, D.F. King, toll-free at 1-800-628-8532.

PROPOSALS SUBMITTED TO MAA SHAREHOLDERS

Merger Proposal

(Proposal 1 on the MAA Proxy Card)

MAA shareholders are asked to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger. For a summary and detailed information regarding this proposal, see the information about the merger agreement and the parent merger throughout this joint proxy statement/prospectus, including the information set forth in sections entitled “The Parent Merger” beginning on page 67 and “The Merger Agreement” beginning on page 147. A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus and incorporated herein by reference.

Pursuant to the merger agreement, approval of this proposal is a condition to the closing of the mergers. If this proposal is not approved, the mergers will not be completed.

MAA is requesting that MAA shareholders approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger. If you return a properly executed proxy card, but do not indicate instructions on your proxy card, your shares of MAA common stock represented by such proxy card will be voted “FOR” the approval of the merger agreement, the parent merger and the other transactions contemplated by the merger agreement.

Approval of the proposal to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement requires the affirmative vote of the holders of at least a majority of the outstanding shares of MAA common stock entitled to vote on such proposal.

Recommendation of the MAA Board

The MAA Board unanimously recommends that MAA shareholders vote FOR the proposal to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger.

2013 Stock Incentive Plan

(Proposal 2 on the MAA Proxy Card)

Proposal

On June 17, 2013, the executive compensation committee of the MAA Board, which we refer to as the MAA Compensation Committee, voted to approve the Mid-America Apartment Communities, Inc. 2013 Stock Incentive Plan, or the MAA 2013 Plan, and the MAA Board is recommending the MAA 2013 Plan to MAA shareholders for approval.

The MAA 2013 Plan will replace the Mid-America Apartment Communities, Inc. 2004 Stock Plan, or the MAA 2004 Plan, which expires by its terms on October 31, 2013. The MAA 2013 Plan provides flexibility to the MAA Compensation Committee to use various equity-based incentive awards as compensation tools to motivate MAA’s workforce. If the MAA 2013 Plan is approved by the shareholders, MAA will no longer make grants under the MAA 2004 Plan. If the MAA 2013 Plan is not approved, the MAA 2004 Plan will expire on October 31, 2013 and MAA will not be able to continue making stock-based incentive awards consistent with historical practices.

The material features of the MAA 2013 Plan are:

•

The award of stock options (both incentive and non-qualified options), restricted stock, restricted stock units, unrestricted stock, performance share awards, other stock-based awards, cash-based awards and dividend equivalent rights is permitted;

•

Any material amendment (other than an amendment that curtails the scope of the MAA 2013 Plan) is subject to approval by MAA’s shareholders;

•

Stock options may not be repriced without shareholder approval; and

•

The term of the MAA 2013 Plan is for ten years from the date of approval by MAA shareholders.

The maximum number of shares of MAA common stock reserved and available for issuance under the MAA 2013 Plan is the sum of (i) 225,000 newly authorized shares, plus (ii) any shares underlying grants under the MAA 2004 Plan that are forfeited, cancelled or terminated (other than by exercise) in the future; such 225,000 shares represent the approximate number of shares of MAA common stock that remain available for issuance under the MAA 2004 Plan, which will expire by its terms on October 31, 2013. Based solely on the closing price of MAA’s common stock as reported by the NYSE on June 28, 2013 of $67.77, the maximum aggregate market value of such 225,000 shares of MAA common stock is $15,248,250. As of June 28, 2013 MAA had outstanding grants of 37,527 shares of restricted MAA common stock. The foregoing, along with the new share request of 225,000 shares (referred to as MAA’s “overhang”), would represent approximately 0.61% of MAA’s total outstanding shares as of June 28, 2013 on a fully diluted basis. Although 0.61% will represent the total overhang if the 2013 Plan is approved, MAA cannot predict the amount or timing of specific equity awards in the future and, thus, it is not possible to calculate the amount of subsequent dilution that may ultimately result from such awards; however, MAA is committed to maintaining an equity incentive program that accomplishes MAA’s incentive and retention goals while being sensitive to shareholders’ concerns about dilution and expense. MAA’s current three-year average burn rate is 0.10%.

The shares available under the MAA 2013 Plan will be authorized but unissued shares. The shares of common stock underlying any awards that are forfeited, cancelled, held back to cover the exercise price or tax withholding, reacquired by MAA prior to vesting, satisfied without the issuance of stock or otherwise terminated (other than by exercise) under the MAA 2013 Plan are added back to the shares of MAA common stock available for issuance under the MAA 2013 Plan.

To ensure that certain awards granted under the MAA 2013 Plan to a “Covered Employee” (as defined in the Code) qualify as “performance-based compensation” under Section 162(m) of the Code, the MAA 2013 Plan provides that the MAA Compensation Committee may require that the vesting of such awards be conditioned on the satisfaction of performance criteria that may include any or all of the following:

•

Funds from operations;

•

Funds from operations per share;

•

Adjusted funds from operations;

•

Adjusted funds from operations per share;

•

Net operating income;

•

Gross operating income;

•

Total shareholder return;

•

Earnings per share;

•

Stock price;

•

Acquisitions;

•

Dispositions;

•

Strategic transactions;

•

Portfolio or regional occupancy rates;

•

Portfolio or regional rent rates;

•

Portfolio or regional revenue rates; or

•

Return on capital, assets, equity, development, or investment.

The MAA Compensation Committee will select the particular performance criteria within 90 days following the commencement of a performance cycle. Subject to adjustments for stock splits and similar events, the maximum award granted to any one individual that is intended to qualify as “performance-based compensation” under Section 162(m) of the Code will not exceed 50,000 shares of MAA common stock for any performance cycle and options with respect to no more than 100,000 shares of common stock may be granted to any one individual during any calendar year period. If a performance-based award is payable in cash to any executive, it cannot exceed $2,500,000 for any performance cycle.

Reasons for the MAA 2013 Plan

The MAA Compensation Committee believes that stock-based incentive awards play an important role in MAA’s success by encouraging and enabling its current employees, officers and non-employee directors upon whose judgment, initiative and efforts it largely depends for the successful conduct of its business to acquire a proprietary interest in MAA. The MAA Compensation Committee anticipates that providing such persons with a direct stake in MAA will assure a closer identification of the interests of participants in the MAA 2013 Plan with those of MAA’s shareholders, thereby stimulating their efforts on MAA’s behalf and strengthening their desire to remain with MAA. The MAA 2004 Plan will expire on October 31, 2013 and the MAA 2013 Plan will therefore enable MAA to continue making such stock-based incentive awards.

Summary of the MAA 2013 Plan

The following description of certain features of the MAA 2013 Plan is intended to be a summary only. The summary is qualified in its entirety by the full text of the MAA 2013 Plan that is attached hereto as Annex E.

Plan Administration

The MAA 2013 Plan will be administered by the MAA Compensation Committee. The MAA Compensation Committee has full power to select, from among the individuals eligible for awards, the individuals to whom awards will be granted, to make any combination of awards to participants, and to determine the specific terms and conditions of each award, subject to the provisions of the MAA 2013 Plan. The MAA Compensation Committee may delegate to MAA’s Chief Executive Officer the authority to grant awards at fair market value to employees who are not subject to the reporting and other provisions of Section 16 of the Exchange Act.

Eligibility and Limitations on Grants

Persons eligible to participate in the MAA 2013 Plan will be those full or part-time officers, employees, non-employee directors and other key persons of MAA and its subsidiaries (including MAA LP) as selected from time-to-time by the MAA Compensation Committee. Approximately 63 individuals are currently eligible to participate in the MAA 2013 Plan.

The maximum award of stock options granted to any one individual will not exceed 100,000 shares of MAA common stock (subject to adjustment for stock splits and similar events) for any calendar year period. If any award of restricted stock, restricted stock units, performance shares or other stock-based award granted to an individual is intended to qualify as “performance-based compensation” under Section 162(m) of the Code, then the maximum award shall not exceed 50,000 shares of MAA common stock (subject to adjustment for stock splits and similar events) to any one such individual in any performance cycle. If any cash-based award is intended to qualify as “performance-based compensation” under Section 162(m) of the Code, then the maximum award to be paid in cash in any performance cycle may not exceed $2,500,000.

Stock Options

The MAA 2013 Plan permits the granting of (1) options to purchase common stock intended to qualify as incentive stock options under Section 422 of the Code and (2) options that do not so qualify. Options granted under the MAA 2013 Plan will be non-qualified options if they fail to qualify as incentive options or exceed the annual limit on incentive stock options. Non-qualified options may be granted to any persons eligible to receive incentive options and to non-employee directors and key persons. The option exercise price of each option will be determined by the MAA Compensation Committee but may not be less than 100% of the fair market value of the MAA common stock on the date of grant. The MAA 2013 Plan provides that such fair market value will be deemed to be the last reported sale price of the shares of MAA common stock on the NYSE on the date of grant. The exercise price of an option may not be reduced after the date of the option grant, other than to appropriately reflect changes in MAA’s capital structure. Option repricing may not be effected through cancellation and re-grants or cancellation in exchange for cash.

The term of each option will be fixed by the MAA Compensation Committee and may not exceed ten years from the date of grant. The MAA Compensation Committee will determine at what time or times each option may be exercised. Options may be made exercisable in installments and the exercisability of options may be accelerated by the MAA Compensation Committee.

Upon exercise of options, the option exercise price must be paid in full either in cash, by certified or bank check or other instrument acceptable to the MAA Compensation Committee, by delivery (or attestation to the ownership) of shares of MAA common stock that are not then subject to restrictions under any MAA plan, or, with respect to stock options that are not incentive stock options, by a “net exercise” arrangement pursuant to which MAA will reduce the number of shares of stock issuable upon exercise by the largest whole number of shares with a fair market value that does not exceed the aggregate exercise price. Subject to applicable law, the exercise price may also be delivered to MAA by a broker pursuant to irrevocable instructions to the broker from the optionee.

To qualify as incentive options, options must meet additional federal tax requirements, including a $100,000 limit on the value of shares subject to incentive options that first become exercisable by a participant in any one calendar year.

Restricted Stock

The MAA Compensation Committee may award shares of common stock to participants subject to such conditions and restrictions as the MAA Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals (as summarized above under “—Proposal”) and/or continued employment with MAA or its subsidiaries through a specified restricted period.

Deferred Stock Awards

The MAA Compensation Committee may award phantom stock units as restricted stock units to participants. Restricted stock units are ultimately payable in the form of shares of common stock and may be

subject to such conditions and restrictions as the MAA Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals (as summarized above) and/or continued employment with MAA or its subsidiaries through a specified vesting period. In the MAA Compensation Committee’s sole discretion and subject to the participant’s compliance with the procedures established by the MAA Compensation Committee and requirements of Section 409A of the Code, it may permit a participant to make an advance election to receive a portion of his or her future cash compensation otherwise due in the form of restricted stock units. During the deferral period, the participant may be credited with dividend equivalent rights with respect to the restricted stock units.

Unrestricted Stock Awards

The MAA Compensation Committee may also grant shares of common stock that are free from any restrictions under the MAA 2013 Plan. Unrestricted stock may be granted to any participant in recognition of past services or other valid consideration and may be issued in lieu of cash compensation due to such participant.

Performance Share Awards

The MAA Compensation Committee may grant performance share awards to any participant that entitle the recipient to receive shares of common stock upon the achievement of certain performance goals (as summarized above) and such other conditions as the MAA Compensation Committee shall determine.

Dividend Equivalent Rights

The MAA Compensation Committee may grant dividend equivalent rights that entitle the recipient to receive credits for dividends that would be paid if the recipient had held specified shares of common stock. Dividend equivalent rights may be granted as a component of another award or as a freestanding award. Dividend equivalent rights may be settled in cash, shares of common stock or a combination thereof, in a single installment or installments, as specified in the award.

Other Stock-Based Awards

The MAA Compensation Committee may grant awards of capital stock other than common stock and other awards that are valued in whole or in part by reference to or are otherwise based on, common stock, including, for example, convertible preferred stock, convertible debentures, exchangeable securities, awards valued by reference to book value or subsidiary performance. These awards may be subject to such conditions and restrictions as the MAA Compensation Committee may determine. These conditions and restrictions may include the achievement of certain performance goals (as summarized above) and/or continued employment with us through a specified vesting period. If the applicable performance goals and other restrictions are not attained, the participant will forfeit his or her awards.

Cash-Based Awards

The MAA Compensation Committee may grant cash bonuses under the MAA 2013 Plan. The cash bonuses may be subject to the achievement of certain performance goals (as summarized above).

Transferability

In general, unless otherwise permitted by the MAA Compensation Committee, no award granted under the MAA 2013 Plan is transferable by the participant other than by will or by the laws of descent and distribution, and awards may be exercised during the participant’s lifetime only by the participant, or by the participant’s legal representative or guardian in the case of the participant’s incapacity.

Adjustments for Stock Dividends, Stock Splits, Etc.

The MAA 2013 Plan requires the MAA Compensation Committee to make appropriate adjustments to the number of shares of common stock that are subject to the MAA 2013 Plan and to any outstanding awards to reflect stock dividends, stock splits, extraordinary cash dividends and similar events.

Tax Withholding

Participants in the MAA 2013 Plan are responsible for the payment of any federal, state or local taxes that MAA is required by law to withhold upon any option exercise or vesting of other awards or election pursuant to Section 83(b) of the Code. Subject to approval by the MAA Compensation Committee, participants may elect to have the minimum tax withholding obligations satisfied by authorizing us to withhold shares of common stock to be issued pursuant to an option exercise or upon vesting of other awards.

Amendments and Termination

The MAA Board may at any time amend or discontinue the MAA 2013 Plan and the MAA Compensation Committee may at any time amend or cancel any outstanding award for the purpose of satisfying changes in the law or for any other lawful purpose. However, no such action may adversely affect any rights under any outstanding award without the holder’s consent. Any amendments that materially change the terms of the MAA 2013 Plan, including any amendments that increase the number of shares reserved for issuance under the MAA 2013 Plan, expand the types of awards available, materially expand the eligibility to participate in, or materially extend the term of, the MAA 2013 Plan, or materially change the method of determining the fair market value of common stock, will be subject to approval by MAA’s shareholders. Amendments shall also be subject to approval by MAA’s shareholders if and to the extent determined by the MAA Compensation Committee to be required by the Code to preserve the qualified status of incentive options or to ensure that compensation earned under the MAA 2013 Plan qualifies as performance-based compensation under Section 162(m) of the Code.

New Plan Benefits

Because the grant of awards under the MAA 2013 Plan is within the discretion of the MAA Compensation Committee, MAA cannot determine the dollar value or number of shares of common stock that will in the future be received by or allocated to any participant in the MAA 2013 Plan. Accordingly, in lieu of providing information regarding benefits that will be received under the MAA 2013 Plan, the following table provides information concerning the benefits that were received by the following persons and groups during 2013: each named executive officer; all current executive officers, as a group; all current directors who are not executive officers, as a group; and all employees who are not executive officers, as a group.

Tax Aspects Under the Code

The following is a summary of the principal U.S. federal income tax consequences of certain transactions under the MAA 2013 Plan. It does not describe all federal tax consequences under the MAA 2013 Plan, nor does it describe state or local tax consequences.

Incentive Options

No taxable income is generally realized by the optionee upon the grant or exercise of an incentive option. If shares of common stock issued to an optionee pursuant to the exercise of an incentive option are sold or transferred after two years from the date of grant and after one year from the date of exercise, then, generally, for U.S. federal income tax purposes, (1) upon sale of such shares, any amount realized in excess of the option price (the amount paid for the shares) will be taxed to the optionee as a long-term capital gain, and any loss sustained will be a long-term capital loss, and (2) we will not be entitled to any deduction. The exercise of an incentive option will give rise to an item of tax preference that may result in alternative minimum tax liability for the optionee.

If shares of common stock acquired upon the exercise of an incentive option are disposed of prior to the expiration of the two-year and one-year holding periods described above (a “disqualifying disposition”), then, generally, for U.S. federal income tax purposes, (a) the optionee will realize ordinary income in the year of disposition in an amount equal to the excess (if any) of the fair market value of the shares of common stock at exercise (or, if less, the amount realized on a sale of such shares of common stock) over the option price thereof, and (b) we will be entitled to deduct such amount. Special rules will apply where all or a portion of the exercise price of the incentive option is paid by tendering shares of common stock. If an incentive option is exercised at a time when it no longer qualifies for the tax treatment described above, the option is treated as a non-qualified option. Generally, an incentive option will not be eligible for the tax treatment described above if it is exercised more than three months following termination of employment (or one year in the case of termination of employment by reason of disability). In the case of termination of employment by reason of death, the three-month rule does not apply.

Non-Qualified Options

No income is realized by the optionee at the time the option is granted. Generally (1) at exercise, ordinary income is realized by the optionee in an amount equal to the difference between the option price and the fair market value of the shares of common stock on the date of exercise, and we receive a tax deduction for the same amount, and (2) at disposition, appreciation or depreciation after the date of exercise is treated as either short-term or long-term capital gain or loss depending on how long the shares of common stock have been held. Special rules will apply where all or a portion of the exercise price of the non-qualified option is paid by tendering shares of common stock. Upon exercise, the optionee will also be subject to Social Security taxes on the excess of the fair market value over the exercise price of the option.

Parachute Payments

The vesting of any portion of an option or other award that is accelerated due to the occurrence of a change in control may cause a portion of the payments with respect to such accelerated awards to be treated as “parachute payments” as defined in the Code. Any such parachute payments may be non-deductible to MAA, in whole or in part, and may subject the recipient to a non-deductible 20% U.S. federal excise tax on all or a portion of such payment (in addition to other taxes ordinarily payable).

Limitation on Deductions

As a result of Section 162(m) of the Code, MAA’s deduction for certain awards under the MAA 2013 Plan may be limited to the extent that the chief executive officer or other executive officer whose compensation is required to be reported in the summary compensation table (other than the chief financial officer) receives compensation in excess of $1 million per year (other than performance-based compensation that otherwise meets the requirements of Section 162(m) of the Code). The MAA 2013 Plan is structured to allow grants to qualify as performance-based compensation.

Approval of the MAA 2013 Plan requires the votes cast “FOR” the proposal exceed the votes cast “AGAINST” the proposal, and in order to satisfy the requirements of the NYSE, the total votes cast on this

proposal must represent over 50% of the shares of outstanding MAA common stock entitled to vote on the proposal. For purposes of the proposal to approve the MAA 2013 Plan, if a MAA shareholder abstains it will count as a vote cast with respect to this proposal and accordingly, abstentions will be included in determining whether the NYSE voting requirement has been achieved, but if the NYSE voting requirement is achieved, it will have no effect on the outcome of the vote for this proposal. If a MAA shareholder fails to vote or fails to instruct its broker, bank or nominee to vote, it will not be counted as votes cast on this proposal and accordingly, it will make it more difficult for the NYSE voting requirement to be achieved, but if the NYSE voting requirement is achieved, it will have no effect on the outcome of the vote for this proposal.

The vote on the approval of the MAA 2013 Plan is a vote separate and apart from the vote to approve the merger agreement and the other transactions contemplated by the merger agreement. You may vote to approve this proposal and vote not to approve the MAA merger proposal, or you may vote against this proposal and vote to approve the merger agreement and the other transactions contemplated by the merger agreement.

Recommendation of the MAA Board

The MAA Board unanimously recommends that MAA shareholders vote FOR the proposal to approve the MAA 2013 Plan.

The MAA Adjournment Proposal

(Proposal 3 on the MAA Proxy Card)

The MAA special meeting may be adjourned to another time or place, if necessary or appropriate in the view of the MAA Board, to permit, among other things, further solicitation of proxies, if necessary or appropriate in the view of the MAA Board, in favor of the other proposals on the MAA proxy card if there are not sufficient votes at the time of such adjournment to approve such proposals.

MAA is asking MAA shareholders to approve the adjournment of the MAA special meeting, if necessary or appropriate in the view of the MAA Board, to solicit additional proxies in favor of the proposals if there are not sufficient votes at the time of such adjournment to approve such proposals. Approval of this proposal requires the affirmative vote of a majority of the votes cast on the proposal.

Recommendation of the MAA Board

The MAA Board unanimously recommends that MAA shareholders vote FOR the proposal to approve one or more adjournments of the MAA special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement and the parent merger.

Other Business

As of the date of this joint proxy statement/prospectus, MAA does not intend to bring any other matters before the MAA special meeting, and MAA has no knowledge of any business that will be presented for consideration at the MAA special meeting and which would be required to be set forth in this joint proxy statement/prospectus other than the matters set forth in the accompanying Notice of Special Meeting of Shareholders of MAA. In accordance with the MAA bylaws and Tennessee law, business transacted at the MAA special meeting will be limited to those matters set forth in such notice. Nonetheless, if any other matter is properly presented at the MAA special meeting for consideration, it is intended that the persons named in the enclosed proxy and acting thereunder will vote in accordance with their discretion on such matter.

THE COLONIAL SPECIAL MEETING

FOR the proposal to approve, on an advisory (non-binding) basis, the compensation payable to certain executive officers of Colonial in connection with the mergers; and

•

FOR the proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement and the parent merger pursuant to the plan of merger.

As discussed elsewhere in this joint proxy statement/prospectus, after careful consideration, and based in part on the unanimous recommendation of the transaction committee of the Colonial Board, the Colonial Board has unanimously approved and adopted the merger agreement and the plan of merger, and has determined that the parent merger is advisable and in the best interests of Colonial and its shareholders. Certain factors considered by the Colonial Board in reaching its decision to adopt and approve the parent merger can be found in the section of this joint proxy/statement/prospectus entitled “The Parent Merger—Recommendation of the Colonial Board and Its Reasons for the Parent Merger” beginning on page 91.

Approval and adoption of the merger agreement and the parent merger pursuant to the plan of merger is subject to a vote by Colonial’s shareholders separate from the vote on approval, on an advisory (non-binding) basis, of the compensation payable to certain executive officers of Colonial in connection with the mergers. Approval of the compensation arrangements is not a condition to completion of the mergers.

Colonial Record Date; Who Can Vote at the Colonial Special Meeting

Only holders of record of Colonial common shares at the close of business on [—], 2013, Colonial’s record date for the Colonial special meeting, are entitled to notice of, and to vote at, the Colonial special meeting or any adjournments or postponements thereof. As of the close of business on the record date, there were [—] Colonial common shares outstanding and entitled to vote at the Colonial special meeting, held by approximately [—] holders of record. Because many of the Colonial common shares are held by brokers and other institutions on behalf of Colonial shareholders, Colonial is unable to estimate the total number of Colonial shareholders represented by these record holders. Colonial common shares are the only security the holders of which are entitled to notice of, and to vote at, the Colonial special meeting.

Each Colonial common share owned on Colonial’s record date is entitled to one vote on each proposal at the Colonial special meeting.

If you own Colonial common shares that are registered in the name of someone else, such as a broker, bank or other nominee, you need to direct that organization to vote those shares or obtain an authorization from them and vote the shares yourself at the Colonial special meeting.

A list of Colonial shareholders entitled to vote at the Colonial special meeting will be open for examination by any Colonial shareholder, for any purpose germane to the Colonial special meeting, during ordinary business hours for a period of ten days before the Colonial special meeting at Colonial’s principal executive offices at 2101 Sixth Avenue North, Suite 750, Birmingham, Alabama 35203, and at the time and place of the Colonial special meeting during the entire time of the Colonial special meeting.

Quorum

The presence at the Colonial special meeting, in person or by proxy, of Colonial shareholders entitled to cast a majority of all the votes entitled to be cast as such meeting will constitute a quorum for purposes of the Colonial special meeting. There must be a quorum for business to be conducted at the Colonial special meeting. It is important that Colonial shareholders vote promptly so that their Colonial common shares are counted toward the quorum.

All Colonial common shares represented at the Colonial special meeting, including abstentions and broker non-votes, will be treated as Colonial common shares that are present for purposes of determining the presence of a quorum. Colonial may seek to adjourn the Colonial special meeting if a quorum is not present at the Colonial special meeting.

Vote Required for Approval

Abstentions and Broker Non-Votes

It is important that you vote your Colonial shares. Your failure to vote, or failure to instruct your broker, bank or other nominee on how to vote, will have the same effect as a vote against the Colonial merger proposal, but will have no effect on the proposal to approve, on an advisory (non-binding) basis, the compensation payable to certain executive officers of Colonial in connection with the mergers or the proposal to approve one or more adjournments of the Colonial special meeting.

If you attend the Colonial special meeting, send in your signed proxy card or vote by telephone or over the Internet, but abstain from voting on any proposal, you will still be counted for purposes of determining whether a quorum exists. If you abstain from voting on the proposal to approve the parent merger and to adopt the plan of

merger, the advisory (non-binding) proposal to approve compensation payable to certain executive officers of Colonial in connection with the mergers or the adjournment proposal, your abstention will have the same effect as a vote against that proposal.

Banks, brokers and other nominees that hold their customers’ shares in street name may not vote their customers’ shares on “non-routine” matters without instructions from their customers. As each of the proposals to be voted upon at the Colonial special meeting is considered “non-routine,” such organizations do not have discretion to vote on any of the proposals. As a result, if you fail to provide your broker, bank or other nominee with any instructions regarding how to vote your Colonial common shares, your Colonial common shares will not be considered present at the Colonial special meeting or voted on any of the proposals. If you provide instructions to your broker, bank or other nominee which do not indicate how to vote your Colonial common shares with respect to a particular proposal, in accordance with stock exchange rules relating to non-routine shareholder matters, your Colonial common shares will not be voted with respect to that particular proposal (this is referred to in this context as a “broker non-vote”). With respect to the proposal to approve, on an advisory (non-binding) basis, the compensation payable to certain executive officers of Colonial in connection with the mergers or the proposal to approve one or more adjournments of the Colonial special meeting, broker non-votes will have no effect on the outcome.

Voting by Colonial Trustees and Executive Officers

Manner of Submitting Proxy

Whether you plan to attend the Colonial special meeting in person, you should submit your proxy as soon as possible.

If you own Colonial common shares in your own name, you are an owner or holder of record. This means that you may use the enclosed proxy card or the Internet or telephone voting options to tell the persons named as proxies how to vote your Colonial common shares. You have four voting options:

•

In Person. To vote in person, come to the Colonial special meeting and you will be able to vote by ballot. To ensure that your Colonial common shares are voted at the Colonial special meeting, the Colonial Board recommends that you submit a proxy even if you plan to attend the Colonial special meeting.

•

Mail. To vote using the enclosed proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the enclosed return envelope. If you return your signed proxy card to Colonial before the Colonial special meeting, Colonial will vote your Colonial common shares as you direct.

•

Telephone. To vote by telephone, dial the toll-free telephone number located on the enclosed proxy card using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. Central Daylight Time on [—], 2013 to be counted.

•

Internet. To vote over the Internet, go to the web address located on the enclosed proxy card to complete an electronic proxy card. You will be asked to provide the company number and control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. Central Daylight Time on [—], 2013 to be counted.

The Internet and telephone voting options available to holders of record are designed to authenticate Colonial shareholders’ identities, to allow Colonial shareholders to give their proxy voting instructions and to confirm that these instructions have been properly recorded. Proxies submitted over the Internet or by telephone through such a program must be received by 11:59 p.m. Central Daylight Time on [—], 2013. Submitting a proxy will not affect your right to vote in person if you decide to attend the Colonial special meeting.

Shares held in “Street Name”

If your Colonial common shares are held in “street name” by your broker, bank or other nominee, you should have received a voting instruction form, as well as voting instructions with these proxy materials from that organization rather than from Colonial. Your broker, bank or other nominee will vote your Colonial common shares only if you provide instructions to that organization on how to vote. You should provide your broker, bank or other nominee with instructions regarding how to vote your Colonial common shares by following the enclosed instructions provided by that organization. Without such instructions, your shares will NOT be voted on any of the proposals to be voted upon at the Colonial special meeting, which will have the same effect as described above under “Abstentions and Broker Non-Votes.”

Please note that Colonial shareholders may not vote Colonial common shares held in street name by returning a proxy card directly to Colonial or by voting in person at the Colonial special meeting unless they provide a “legal proxy,” which Colonial shareholders must obtain from their broker, bank or nominee. Further, brokers, banks or nominees who hold Colonial common shares on behalf of their customers may not give a proxy to Colonial to vote those Colonial common shares without specific instructions from their customers

Revocation of Proxies or Voting Instructions

Your grant of a proxy on the enclosed proxy card or through one of the alternative methods discussed above does not prevent you from voting in person or otherwise revoking your proxy at any time before it is voted at the Colonial special meeting. If your Colonial common shares are registered in your own name, you may revoke your proxy in one of the following ways by:

•

submitting notice in writing to Colonial’s Corporate Secretary at Colonial Properties Trust, 2101 Sixth Avenue North, Suite 750, Birmingham, Alabama 35203, that you are revoking your proxy that bears a date later than the date of the proxy that you are revoking and that is received before the Colonial special meeting;

•

submitting another proxy card bearing a later date and mailing it so that it is received before the Colonial special meeting;

•

submitting another proxy using the Internet or telephone voting procedures; or

•

attending the Colonial special meeting and voting in person, although simply attending the Colonial special meeting will not revoke your proxy, as you must deliver a notice of revocation or vote at the Colonial special meeting in order to revoke a prior proxy.

Your last vote is the vote that will be counted.

If you have instructed a broker, bank or other nominee to vote your Colonial common shares, you must follow the directions received from your broker, bank or other nominee if you wish to change your vote.

If you have questions about how to vote or revoke your proxy, you should contact our proxy solicitor, Morrow & Co., LLC toll-free at (800) 460-1014.

Tabulation of Votes

Colonial will appoint an inspector of election for the Colonial special meeting to tabulate affirmative and negative votes, broker non-votes and abstentions.

Solicitation of Proxies; Payment of Solicitation Expenses

Colonial is soliciting proxies for the Colonial special meeting from Colonial shareholders. Colonial will bear the entire cost of soliciting proxies from Colonial shareholders. In addition to this mailing, Colonial’s trustees and officers may solicit proxies by telephone, by facsimile, by mail, over the Internet or in person. They will not be paid any additional amounts for soliciting proxies. Arrangements also will be made with brokerage firms and other custodians, nominees and fiduciaries to forward proxy solicitation materials to the beneficial owners of Colonial common shares held of record by those persons, and Colonial will reimburse these brokerage firms, custodians, nominees and fiduciaries for related, reasonable out-of-pocket expenses they incur.

Colonial has engaged Morrow & Co. to assist in the solicitation of proxies for the Colonial special meeting and will pay Morrow & Co. a fee of approximately $25,000, plus reimbursement of out-of-pocket expenses and will indemnify Morrow & Co. and its affiliates against certain claims, liabilities, losses, damages and expenses. The address of Morrow & Co. is 470 West Avenue, Stamford, CT 06902. You can call Morrow & Co., LLC at (203) 658-9400 or toll-free at (800) 460-1014.

Adjournment

In addition to the other proposals being considered at the Colonial special meeting, Colonial shareholders are also being asked to approve a proposal that will give the Colonial Board authority to adjourn the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement and the parent merger pursuant to the plan of merger. If this proposal is approved, the Colonial special meeting could be successively adjourned to any date. In addition, the Colonial Board could postpone the Colonial special meeting before it commences, whether for the purpose of soliciting additional proxies or for other reasons. If the Colonial special meeting is adjourned for the purpose of soliciting additional proxies, Colonial shareholders who have already submitted their proxies will be able to revoke them at any time prior to their use.

Whether a quorum is present, upon the affirmative vote of the holders of a majority of the Colonial common shares present in person or represented by proxy at the Colonial special meeting and entitled to vote on the adjournment, Colonial may adjourn the Colonial special meeting.

Rights of Dissenting Shareholders

Under the AREITL, Colonial shareholders are entitled to dissenters’ rights of appraisal with respect to Colonial common shares that are the same rights as a dissenting shareholder of an Alabama business corporation. Therefore, pursuant to Section 10A-2-13.01 et seq. of the ABCL (“ABCL Article 13”), holders of Colonial common shares are entitled to dissenters’ rights of appraisal in connection with the parent merger. This means that, subject to the parent merger being consummated, you are entitled to payment by MAA of the “fair value” (as defined in ABCL Article 13) of such dissenting Colonial common shares plus accrued interest in accordance with ABCL Article 13. The ultimate amount you receive in an appraisal proceeding may be less than, equal to or more than the amount you would have received under the merger agreement. To exercise your dissenters’ rights, you must submit a written demand for dissenters’ rights of appraisal to Colonial before the shareholder vote is taken on the merger agreement and plan of merger, and you must not vote in favor of the proposal to adopt the merger agreement. Colonial common shares held by shareholders who properly demand and exercise their dissenters’ rights of appraisal pursuant to ABCL Article 13 will not be converted into the right to receive the merger consideration. Your failure to follow exactly the procedures specified under ABCL Article 13 may result in the loss of your dissenters’ rights of appraisal. See “Dissenters’ Rights” beginning on page 173 and the text of ABCL Article 13 reproduced in its entirety as Annex H to this joint proxy statement/prospectus. If you hold your Colonial common shares through a broker, bank or other nominee and you wish to exercise dissenter’s rights, you should consult such organization to determine the appropriate procedures for the making of a demand for dissenters’ rights by that organization. In view of the complexity of the ABCL, shareholders who may wish to pursue dissenters’ rights should consult their legal and financial advisors.

PROPOSALS SUBMITTED TO COLONIAL SHAREHOLDERS

Merger Proposal

(Proposal 1 on the Colonial Proxy Card)

Colonial shareholders are asked to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement. For a summary and detailed information regarding this proposal to approve and adopt the merger agreement, the parent merger pursuant to plan of merger and the other transactions contemplated by the merger agreement, see the information about the merger agreement and the parent merger throughout this joint proxy statement/prospectus, including the information set forth in sections entitled “The Parent Merger” beginning on page 67 and “The Merger Agreement” beginning on page 147. A copy of the merger agreement is attached as Annex A to this joint proxy statement/prospectus and a copy of the plan of merger is attached as Annex B to this joint proxy statement/prospectus, each of which is incorporated by reference herein.

Pursuant to the merger agreement, approval of this proposal is a condition to the closing of the mergers. If the proposal is not approved, the mergers will not be completed even if the other proposals considered at the Colonial special meeting are approved.

Colonial is requesting that Colonial shareholders approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement. If you return a properly executed proxy card, but do not indicate instructions on your proxy card, your Colonial common shares represented by such proxy card will be voted “FOR” the approval and adoption of the merger agreement, the parent merger pursuant to plan of merger and the other transactions contemplated by the merger agreement.

Approval of the proposal to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement requires the affirmative vote of the holders of at least a majority of the outstanding Colonial common shares entitled to vote on such proposal.

Recommendation of the Colonial Board

The Colonial Board unanimously recommends that Colonial shareholders vote FOR the proposal to approve and adopt the merger agreement, the parent merger pursuant to plan of merger and the other transactions contemplated by the merger agreement.

Advisory Vote on Executive Compensation

(Proposal 2 on the Colonial Proxy Card)

As required by Section 14A of the Exchange Act and the SEC’s rules thereunder, Colonial is asking its shareholders to cast an advisory (non-binding) vote on the compensation that may be payable to its named executive officers in connection with the mergers, as described in this joint proxy statement/prospectus under “The Parent Merger—Executive Compensation Payable in Connection with the Mergers—Change in Control Compensation,” including in the associated narrative discussion. In accordance with these requirements, Colonial is asking its shareholders to vote on the adoption of the following resolution:

“RESOLVED, that the compensation that may be payable to Colonial’s named executive officers in connection with the mergers, as disclosed in the table captioned “Change in Control Compensation” on page 121 under “The Parent Merger—Executive Compensation Payable in Connection with the Mergers,” including the associated narrative discussion, and the agreements or understandings pursuant to which such compensation may be payable, are hereby APPROVED.”

The vote on the executive compensation payable in connection with the mergers is a vote separate and apart from the vote to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement. You may vote to approve this proposal and vote not to approve the Colonial merger proposal, or you may vote against this proposal and vote to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement. Because the vote on this proposal is advisory in nature only, it will not be binding on Colonial. Accordingly, because Colonial is contractually obligated to pay the compensation covered by this proposal, such compensation will be payable, subject only to certain applicable conditions, if the parent merger is approved and regardless of the outcome of the advisory vote.

The affirmative vote of the holders of a majority of Colonial common shares present in person or represented by proxy at the Colonial special meeting and entitled to vote on this proposal will be required to approve the proposal. If you return a properly executed proxy card, but do not indicate instructions on your proxy card, your shares of common stock represented by such proxy card will be voted “FOR” this proposal. Abstentions from voting on this proposal will have the same effect as a vote against this proposal. Failures to submit a proxy (if you do not attend the Colonial special meeting in person) and any broker non-votes will not affect the outcome of the vote on this proposal.

Recommendation of the Colonial Board

The Colonial Board unanimously recommends that Colonial shareholders vote FOR the proposal to approve, on an advisory (non-binding) basis, the compensation payable to certain executive officers of Colonial in connection with the mergers.

Colonial Adjournment Proposal

(Proposal 3 on the Colonial Proxy Card)

Colonial is asking its shareholders to consider and vote upon a proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement and the parent merger pursuant to the plan of merger.

If the number of Colonial common shares present in person or represented by proxy at the Colonial special meeting voting in favor of proposal 1 to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement is insufficient to approve proposal 1 at the time of the Colonial special meeting, then Colonial may move to adjourn the Colonial special meeting in order to enable the Colonial Board to solicit additional proxies in respect of such proposal. In that event, Colonial shareholders will be asked to vote only upon the adjournment proposal, and not on any other proposal, including proposal 1.

In this proposal, you are being asked to authorize the holder of any proxy solicited by the Colonial Board to vote in favor of granting discretionary authority to the proxy or attorney-in-fact to adjourn the Colonial special meeting one or more times for the purpose of soliciting additional proxies. If Colonial shareholders approve the adjournment proposal, Colonial could adjourn the Colonial special meeting and any adjourned session of the Colonial special meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Colonial shareholders that have previously returned properly executed proxies or authorized a proxy by using the Internet or telephone. Among other things, approval of the adjournment proposal could mean that, even if Colonial has received proxies representing a sufficient number of votes against the approval of proposal 1 such that the proposal would be defeated, Colonial could adjourn the Colonial special meeting without a vote on proposal 1 and seek to obtain sufficient votes in favor of approval of proposal 1 to obtain approval of that proposal.

Whether a quorum is present, the affirmative vote of the holders of a majority of Colonial common shares present in person or represented by proxy at the Colonial special meeting and entitled to vote on this proposal will be required to approve the proposal. If you return a properly executed proxy card, but do not indicate instructions on your proxy card, your Colonial common shares represented by such proxy card will be voted “FOR” this proposal. Abstentions from voting on this proposal will have the same effect as a vote against this proposal. Failures to submit a proxy (if you do not attend the Colonial special meeting in person) and any broker non-votes will not affect the outcome of the vote on this proposal.

Recommendation of the Colonial Board

The Colonial Board unanimously recommends that Colonial shareholders vote FOR the proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement and the parent merger pursuant to the plan of merger.

Other Business

At this time, Colonial does not intend to bring any other matters before the Colonial special meeting, and Colonial does not know of any matters to be brought before the Colonial special meeting by others. If, however, any other matters properly come before the Colonial special meeting, the persons named in the enclosed proxy, or their duly constituted substitutes, acting at the Colonial special meeting or any adjournment or postponement thereof will be deemed authorized to vote the Colonial common shares represented thereby in accordance with the judgment of management on any such matter.

THE PARENT MERGER

The following is a description of the material aspects of the parent merger. While MAA and Colonial believe that the following description covers the material terms of the parent merger, the description may not contain all of the information that is important to the MAA shareholders and the Colonial shareholders. MAA and Colonial encourage the MAA shareholders and the Colonial shareholders to carefully read this entire joint proxy statement/prospectus, including the merger agreement and the other documents attached to this joint proxy statement/prospectus and incorporated herein by reference, for a more complete understanding of the parent merger.

General

Each of the MAA Board and the Colonial Board has unanimously approved the merger agreement, the parent merger and the other transactions contemplated by the merger agreement. In the parent merger, Colonial will merge with and into MAA, with MAA continuing as the Combined Corporation, and Colonial shareholders will receive the merger consideration described below under “The Merger Agreement—Merger Consideration; Effects of the Parent Merger and the Partnership Merger.”

Background of the Mergers

The boards and management teams of Colonial and MAA periodically and in the ordinary course have evaluated and considered a variety of financial and strategic opportunities as part of their respective long-term strategies to enhance value for their shareholders.

Prior to April 2012, Colonial from time to time engaged in discussions regarding a variety of possible business opportunities, including discussions with other companies in Colonial’s industry. These discussions ranged from possible commercial or partnering arrangements to possible acquisitions by or of Colonial or other business combination transactions. Colonial received, on occasion, unsolicited inquiries from third parties regarding possible business combinations or other strategic transaction opportunities. On occasion prior to April 2012, as part of its ongoing evaluation of its business strategy and business opportunities, Colonial engaged in discussions regarding possible strategic transactions, including discussions with another public multifamily REIT, referred to in this joint proxy statement/prospectus as “Company A,” and a real estate investment and management services firm, referred to in this joint proxy statement/prospectus as “Company B,” which in each case were both brief and preliminary.

In January 2012, Colonial received an unsolicited letter addressed to the executive committee of the Colonial Board from the chairman and chief executive officer of a national operator of multifamily apartments, referred to in this joint proxy statement/prospectus as “Company C.” The letter expressed an interest in exploring a potential business combination with Colonial and specified an initial indication of value of $22 to $25 in cash per outstanding Colonial common share, noting that the ultimate valuation determination would be made following completion of Company C’s diligence review. The letter did not contain any other terms regarding a proposed combination. The Colonial Board, of which Mr. Thomas H. Lowder—Colonial’s Chief Executive Officer—serves as chairman, discussed the letter from Company C during its regular, in person board meeting at Colonial’s headquarters in Birmingham, Alabama on January 24, 2012, at which meeting a representative of Colonial’s outside legal advisor, Hogan Lovells US LLP, herein referred to as Hogan Lovells, was present telephonically. Based on the preliminary nature of Company C’s expression of interest and its lack of material terms other than a preliminary indication of value, the Colonial Board’s view that the price range expressed in the letter was inadequate for a sale transaction of this type, Colonial management’s familiarity with Company C and its concern with Company C’s ability to structure and consummate a transaction of this type and complexity, the Colonial Board determined not to proceed with further discussions with Company C at that time.

Beginning in the spring 2012, Colonial’s improved financial position, resulting from Colonial’s improved operating performance and reduced debt levels, improvements in general economic conditions and financial markets and strong multifamily industry fundamentals led the Colonial Board to assess its current business

strategy in light of other possible strategic alternatives. At Colonial’s regular, in person board meeting at Colonial’s headquarters in Birmingham on April 25, 2012, the Colonial Board invited BofA Merrill Lynch to discuss with the Colonial Board potential strategic alternatives for Colonial and subsequently engaged BofA Merrill Lynch as Colonial’s financial advisor. Representatives of Hogan Lovells and Edward Hardin, co-general counsel of Colonial, and counsel with Burr & Forman LLP, herein referred to as Burr Forman, were also present. Potential strategic alternatives discussed at this meeting included potential sale, merger and acquisition opportunities. During the discussion, the Colonial Board further discussed Colonial’s improved financial position, improvements in the financial markets and strong multifamily industry fundamentals as well as the potential benefits to Colonial shareholders if a transaction were structured to allow them to continue to participate in the ongoing success of Colonial’s business. As a result, the discussions were focused principally on the possibility of a strategic combination transaction with other multifamily REITs, including MAA and Company A. Following this discussion, the Colonial Board authorized Mr. Lowder to contact representatives of MAA and Company A in an effort to determine whether there was interest by either such party in discussing a possible strategic combination transaction with Colonial.

In early May 2012, Mr. Lowder spoke by telephone with the chief executive officer of Company A. Mr. Lowder and the chief executive officer of Company A discussed the multifamily industry generally, as well as their respective companies. During this discussion, Mr. Lowder inquired whether Company A would have interest in considering a possible strategic combination of the two companies. This discussion was limited to a preliminary inquiry and did not address any specific terms of a possible transaction. At the end of the discussion, Mr. Lowder suggested that the chief executive officer of Company A contact Mr. Lowder if Company A was interested in engaging in further discussions regarding a possible strategic combination with Colonial. After this discussion, the chief executive officer of Company A did not contact Mr. Lowder or Colonial to engage in further discussions, and representatives of Colonial and Company A did not engage in further discussions regarding a potential strategic combination transaction.

On May 9, 2012, Mr. Lowder contacted H. Eric Bolton, Jr., Chairman and Chief Executive Officer of MAA, to inquire about whether MAA would be interested in exploring a potential strategic combination transaction with Colonial. As part of this conversation, Messrs. Lowder and Bolton discussed the potential strategic merits of combining the companies to create a leading Sunbelt-focused multifamily REIT. During the subsequent week, Mr. Bolton contacted each director of MAA individually by telephone to inform them of his conversation with Mr. Lowder and advise them that a potential strategic transaction with Colonial would be discussed at the next regular quarterly meeting of the MAA Board.

Subsequent to the May 9, 2012 meeting, Messrs. Bolton and Lowder contacted each other by telephone and email to make arrangements for an in person meeting to discuss a potential strategic combination transaction between MAA and Colonial further.

On May 24, 2012, the MAA Board held a regular quarterly meeting in Memphis with members of senior management and representatives of Baker, Donelson, Bearman, Caldwell & Berkowitz, PC, herein referred to as Baker Donelson. At this meeting, Mr. Bolton summarized his communications with Mr. Lowder and made a presentation to the MAA Board that provided a preliminary overview of Colonial including, among other things, information regarding Colonial’s history, strategy, core and non-core properties, financial condition, management and trustees. The MAA Board further discussed its interest in a potential strategic transaction with Colonial, but also discussed that it would likely not be interested in owning Colonial’s non-core assets long-term. The MAA Board then reviewed several financial metrics for Colonial and MAA and also reviewed Colonial’s publicly available financial statements. Next, Mr. Bolton and the MAA Board discussed the potential impact of combining the MAA and Colonial portfolios and certain terms of a potential strategic combination transaction, including conditions, pricing, synergies and costs with respect to such potential transaction. Mr. Bolton then reviewed with the MAA Board certain considerations for a potential transaction with Colonial, including potential benefits to MAA and its shareholders and integration and other challenges associated with a potential strategic combination transaction with Colonial.

On July 11, 2012 and July 12, 2012, Messrs. Bolton and Lowder met in Memphis to discuss a potential strategic combination transaction. Messrs. Bolton and Lowder discussed, among other things, the location of the Combined Corporation’s corporate headquarters, key executive positions of MAA and Colonial, synergy opportunities from the combination of MAA’s and Colonial’s respective platforms, MAA’s and Colonial’s respective portfolios and strategies, the likely future of the publicly-traded apartment sector and scale-related advantages.

In mid-July, 2012, Mr. Lowder received and returned an unsolicited telephone call from the chairman and chief executive officer of Company C. The chairman and chief executive officer of Company C expressed interest in meeting with Mr. Lowder to discuss a possible strategic acquisition transaction. Mr. Lowder informed the chairman and chief executive officer of Company C of the Colonial Board’s concerns with respect to a proposed transaction with Company C and declined to engage in a substantive discussion regarding a possible strategic acquisition transaction with Company C. After this discussion, Mr. Lowder did not have any further discussions with the chairman and chief executive officer of Company C.

On July 25, 2012, the Colonial Board held a regular, in person meeting at Colonial’s headquarters in Birmingham with Mr. Hardin present. During this meeting, Mr. Lowder updated the Colonial Board regarding developments since the April 2012 Board meeting, including Mr. Lowder’s telephone discussion in May 2012 with the chief executive officer of Company A. Mr. Lowder also updated the Colonial Board regarding Mr. Lowder’s communications with Mr. Bolton regarding a possible strategic business combination transaction. Mr. Lowder also reported to the Colonial Board regarding his telephone discussion in mid-July with the chairman and chief executive officer of Company C. Following discussion, the Colonial Board determined that Colonial should continue to consider the possibility of a strategic combination with MAA and authorized Mr. Lowder to continue preliminary discussions with MAA regarding a potential strategic business combination transaction.

On July 31, 2012, the MAA Board held a special telephonic meeting with members of senior management and representatives of Baker Donelson. During the meeting, Mr. Bolton provided a summary to the MAA Board of the meetings with Mr. Lowder and other developments related to evaluating a possible strategic combination transaction with Colonial.

On August 15, 2012, the MAA Board held a special telephonic meeting with members of senior management and representatives of Baker Donelson during which Mr. Bolton updated the MAA Board on his August 8, 2012 call with Mr. Lowder. The MAA Board then discussed the engagement of legal and financial advisors.

On or about August 16, 2012, pursuant to the recommendations of the MAA Board, Mr. Bolton contacted Goodwin Procter LLP, herein referred to as Goodwin Procter, and J.P. Morgan to act as counsel and financial advisor, respectively, for MAA in a potential strategic combination transaction with Colonial.

On August 28, 2012, the MAA Board held a special telephonic meeting with members of senior management and representatives of Baker Donelson. During the meeting, Mr. Bolton updated the MAA Board that the Colonial Board was expected to meet to discuss potential strategic alternatives for Colonial. Mr. Bolton then summarized his recent discussions with J.P. Morgan regarding its preliminary assessment of the feasibility and potential structure of a proposal to Colonial. The MAA Board next discussed valuation and structuring options for a proposed strategic combination transaction with Colonial and potential earnings impact of a transaction on MAA.

On August 30, 2012, the Colonial Board held an in person meeting in Atlanta, Georgia with Mr. Hardin and representatives of BofA Merrill Lynch present. During this meeting, the Colonial Board reviewed and discussed Colonial’s business plan and strategy and potential strategic alternatives. Potential strategic alternatives discussed at this meeting included potential sale, merger and acquisition opportunities. As part of this discussion, Colonial’s financial advisor discussed financial matters relating to a possible strategic transaction with MAA or Company A. Mr. Lowder reminded the Colonial Board of Mr. Lowder’s various communications with

Mr. Bolton since May 2012, as well as Mr. Lowder’s telephone discussion in May 2012 with the chief executive officer of Company A. The Colonial Board also discussed certain issues associated with a cash sale transaction or auction process, including the risks and uncertainties associated with a buyer’s financing of a cash sale transaction and the potential detrimental effects on Colonial’s business from solicitation activities that occur prior to entering into and announcing a transaction. Following this discussion, the Colonial Board determined that Colonial should continue pursuing a strategy that offers Colonial shareholders the prospect of continued participation in long-term value creation. The Colonial Board also agreed that Colonial should continue preliminary discussions with MAA regarding the possibility of a strategic business combination transaction.

On September 11, 2012, Messrs. Bolton and Lowder, together with Albert M. Campbell III, Executive Vice President and Chief Financial Officer of MAA, and John W. Spiegel, an independent trustee of Colonial, met in Atlanta. Messrs. Bolton, Lowder, Campbell and Spiegel discussed the state of the apartment industry generally and potential business strategies. Messrs. Bolton and Campbell indicated that the parties would need to sign a confidentiality agreement and exchange information before MAA provided a written proposal for a potential strategic combination transaction.

On September 18, 2012, the MAA Board held a special in person meeting with members of senior management and representatives of J.P. Morgan, Goodwin Procter and Baker Donelson present in person or by telephone. Mr. Bolton provided a summary to the MAA Board of his meeting with Messrs. Lowder and Spiegel. Representatives of J.P. Morgan next presented a preliminary financial analysis relating to a potential strategic combination transaction with Colonial. The MAA Board also discussed with J.P. Morgan the strategic rationale of a potential transaction, certain preliminary financial information on each of MAA and Colonial, structural considerations and possible next steps in exploring a strategic combination transaction with Colonial. The MAA Board then instructed Mr. Bolton to continue discussions with Mr. Lowder regarding a strategic combination transaction.

On September 21, 2012, Messrs. Bolton and Lowder spoke by telephone. Mr. Bolton indicated that MAA was interested in pursuing a strategic combination transaction with Colonial given the strategic merits of the combination. During the conversation, Mr. Bolton highlighted that in order to proceed, both parties would need to share confidential information in order to best assess the opportunity. Mr. Bolton also noted that, given the strategic nature of the proposed transaction, both the anticipated level of synergies and the valuation of both MAA and Colonial would be important considerations in connection with evaluating whether to proceed with the proposed combination. Mr. Lowder indicated that the Colonial Board would further discuss a proposed strategic combination transaction with MAA.

On October 24, 2012, the Colonial Board held a regular, in person meeting at Colonial’s headquarters in Birmingham with Mr. Hardin present. During this meeting, Mr. Lowder updated the Colonial Board regarding the status of discussions with MAA since the August 30^th Colonial Board meeting. Following discussion, the Colonial Board authorized Colonial management to enter into a confidentiality agreement with MAA to permit the exchange of non-public information in connection with the Colonial Board’s ongoing consideration of a possible strategic combination transaction with MAA.

On October 25, 2012, Mr. Lowder contacted Mr. Bolton by telephone and Mr. Lowder advised that Colonial was prepared to execute a confidentiality agreement, exchange further information and begin negotiations for a proposed strategic combination transaction.

On October 30, 2012, MAA and Colonial, with the assistance of their respective advisors, negotiated and entered into a confidentiality agreement that included mutual standstill and confidentiality restrictions.

On November 12, 2012, MAA and Colonial provided one another with access to an electronic data room containing due diligence materials.

On November 19, 2012, Mr. Bolton provided a written update to the MAA Board describing, among other things, the due diligence review of materials provided by Colonial in its electronic data room.

On November 27, 2012, Messrs. Bolton and Lowder met in Memphis to discuss considerations related to the proposed strategic combination transaction, including potential synergies and timing considerations. As part of the meeting, Mr. Lowder requested an outline of the basic terms of a transaction proposal.

Also on November 27, 2012, the management teams of both MAA and Colonial held a telephonic meeting with representatives of J.P. Morgan and BofA Merrill Lynch present to review the non-core assets owned and controlled by Colonial.

On December 4, 2012, the MAA Board held an in person regular quarterly meeting in Memphis with members of senior management and representatives of Baker Donelson, with representatives from J.P. Morgan and Goodwin Procter participating by telephone. Representatives from J.P. Morgan reviewed the discussions and meetings that had occurred since the last MAA Board meeting and presented a preliminary financial analysis of Colonial. The MAA Board discussed a proposed draft non-binding term sheet, as well as Colonial’s non-core assets, operating strategy and potential synergies that could result from the proposed combination with Colonial. Representatives from Goodwin Procter then discussed legal matters surrounding the term sheet with the MAA Board, including board composition, proposed conditions precedent to closing and mutual non-solicitation of competing transactions.

Also on December 4, 2012, the Nominating and Corporate Governance Committee of the MAA Board held a meeting to discuss the potential composition of the Combined Corporation’s board of directors in a proposed transaction with Colonial and a potential waiver of the MAA Board’s age limitation for General John S. Grinalds so that he could remain a member of the MAA Board for an additional year to assist in matters related to the proposed strategic transaction with Colonial.

On December 10, 2012, the MAA Board held a special telephonic meeting with members of senior management and representatives from J.P. Morgan, Goodwin Procter and Baker Donelson. Representatives of J.P. Morgan presented materials to the MAA Board containing, among other things, preliminary financial analyses relating to a combination between MAA and Colonial. The MAA Board then discussed various aspects of a proposed non-binding term sheet with Colonial. Following the discussion, the MAA Board authorized Mr. Bolton to deliver the non-binding term sheet to Colonial, proposing an exchange ratio of 0.340 of a share of MAA common stock per outstanding Colonial common share.

On December 11, 2012, MAA submitted the non-binding term sheet to Colonial, which provided for, among other things, an exchange ratio of 0.340 of a share of MAA common stock per outstanding Colonial common share and that the Combined Corporation would retain the MAA name and management team.

Also on December 11, 2012, Messrs. Bolton and Lowder met in Birmingham to discuss the material terms of the non-binding term sheet and to explain the rationale for those terms. Following the meeting, Mr. Bolton provided a written update to the MAA Board regarding his conversation with Mr. Lowder.

On December 12, 2012, at MAA’s and Colonial’s request, representatives from J.P. Morgan and BofA Merrill Lynch met to discuss the proposed financial terms presented by MAA to Colonial, including a review of financial metrics.

On December 16, 2012, the Colonial Board held a special telephonic meeting with Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells present. The Colonial Board reviewed and discussed the proposed strategic combination with MAA as well as the MAA proposal received on December 11^th. BofA Merrill Lynch discussed with the Colonial Board, among other things, financial matters relating to Colonial and financial terms and other aspects of MAA’s proposal. During this meeting, the Colonial Board reviewed certain valuation approaches utilized by MAA and Colonial, including assumptions regarding, among other things, anticipated growth and expected synergies. The Colonial Board members also reviewed and discussed a proposed response to MAA’s exchange ratio proposal. In addition, the Colonial Board members discussed that, under the MAA proposal, MAA’s management would have responsibility for management of the Combined Corporation

and MAA’s board members would constitute a majority of the initial members of the board of directors of the Combined Corporation. Following discussion, the Colonial Board determined to propose an alternative exchange ratio of 0.370 of a share of MAA common stock for each outstanding Colonial common share, which reflected an implied value of approximately $23.40 per Colonial common share as of December 14, 2012.

On December 17, 2012, Colonial submitted a counterproposal to MAA, which provided for, among other things, an exchange ratio of 0.370 of a share of MAA common stock per outstanding Colonial common share.

On December 17, 2012 and December 19, 2012, Messrs. Bolton and Lowder met both in person in Memphis and by telephone to discuss the terms of Colonial’s counterproposal.

On December 19, 2012, the MAA Board held a special telephonic meeting with members of senior management and representatives from J.P. Morgan, Goodwin Procter and Baker Donelson. Mr. Bolton summarized for the MAA Board the meetings and discussions that had occurred since the previous MAA Board meeting and reviewed the counterproposal received from Colonial. The MAA Board then discussed the terms of Colonial’s counterproposal, including its assumptions and exchange ratio. Mr. Bolton also discussed the factors considered in establishing the exchange ratio and emphasized the need for any potential transaction with Colonial to create value for MAA shareholders. Representatives from J.P. Morgan next presented a preliminary financial analysis of the counterproposal and an analysis of the proposed transaction at different exchange ratios. The MAA Board then discussed various exchange ratios that would create value for MAA shareholders. The MAA Board then formally authorized Mr. Bolton to continue discussions with Colonial.

On December 20, 2012, Mr. Bolton delivered to Mr. Lowder a letter in response to Colonial’s counterproposal outlining the strategic rationale for the proposed transaction and providing for an exchange ratio of 0.349 of a share of MAA common stock per outstanding Colonial common share.

On December 21, 2012, the Colonial Board held a telephonic meeting, with Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells present. During this meeting, Mr. Lowder summarized his recent discussions with Mr. Bolton and MAA’s December 20^th written response. The Colonial Board members discussed MAA’s written response, including MAA’s rationale in support of its exchange ratio proposal and synergy assumptions included in such written response. BofA Merrill Lynch discussed with the Colonial Board, among other things, financial terms of the MAA proposal, the relative contributions of Colonial and MAA to the Combined Corporation and certain related financial matters. During this discussion, the legal advisors discussed with the Colonial Board certain fiduciary considerations in the context of the Colonial Board’s consideration of a potential strategic combination transaction. The Colonial Board also discussed various alternative exchange ratios and resulting implied premiums and authorized Mr. Lowder to propose an exchange ratio of 0.360 of a share of MAA common stock for each outstanding Colonial common share, which reflected an implied value of approximately $23.25 per Colonial common share as of December 20, 2012.

On December 23, 2012, Mr. Lowder delivered to Mr. Bolton Colonial’s revised counterproposal, which provided for an exchange ratio of 0.360 of a share of MAA common stock per outstanding Colonial common share.

On December 27, 2012, the MAA Board held a special telephonic meeting with members of senior management. Mr. Bolton reviewed the events that had occurred since the previous MAA Board meeting and reviewed Colonial’s counterproposal delivered on December 23, 2012. The MAA Board discussed the changed assumptions reflected in Colonial’s counterproposal and resulting impact on value for MAA shareholders. Mr. Bolton then discussed the factors considered in establishing the exchange ratio and discussed the due diligence that would be conducted to evaluate the underlying assumptions. Mr. Bolton then discussed with the MAA Board a range of exchange ratios that would provide sufficient value to MAA shareholders. After the discussions, the MAA Board authorized Mr. Bolton to continue discussions with Colonial.

Also on December 27, 2012, Messrs. Bolton and Lowder spoke by telephone. Messrs. Bolton and Lowder discussed Colonial’s counterproposal from December 23, 2012 and Mr. Bolton proposed an exchange ratio of 0.3545 of a share of MAA common stock per outstanding Colonial common share, reflecting the midpoint between the 0.349 exchange ratio last proposed by MAA and the 0.360 exchange ratio last proposed by Colonial. Mr. Lowder informed Mr. Bolton that, based on the discussions with the Colonial Board, Colonial was not in a position to proceed with further discussions regarding a possible strategic transaction based on MAA’s proposal, and discussions were terminated.

Between early January 2013 and late March 2013, Colonial’s management team and financial advisor received several unsolicited inquiries via telephone and e-mail from third parties inquiring whether Colonial had an interest in considering a strategic transaction. None of these unsolicited inquiries included a proposed price or price range or other proposed terms of a potential transaction or, except in the case of Company B and Company D, resulted in any further discussions. The Colonial Board or, as noted below, the executive committee of the Colonial Board, herein referred to as the Colonial Executive Committee, considered and discussed each of these communications and, except with respect to Company B and Company D, decided, given the absence of any proposed terms and the uncertainty regarding any such party’s ability to complete such a strategic transaction with Colonial, not to pursue discussions with the inquiring parties.

On January 21, 2013, Mr. Bolton provided a written update to the MAA Board regarding the proposed strategic combination transaction with Colonial. Mr. Bolton advised the MAA Board that no further discussions had been held with Colonial since December 27, 2012. Mr. Bolton summarized MAA’s most recent proposal to Colonial and the key metrics supporting that proposal. Mr. Bolton advised that, although the opportunity could re-emerge later, MAA would not actively pursue the proposed strategic transaction with Colonial at that time.

On January 29, 2013, Colonial’s financial advisor received an unsolicited written inquiry from the chief executive officer of a real estate management company, referred to in this joint proxy statement/prospectus as “Company D,” indicating that Company D was interested in exploring a potential all-cash acquisition of Colonial. The unsolicited written inquiry indicated that the all-cash amount would be at a premium to Colonial’s then current stock price, but did not include a proposed price, price range or other specific terms of a potential transaction. On or about January 30, 2013, Mr. Lowder received and returned an unsolicited telephone call from the chief executive officer of Company D. During the telephone call, the chief executive officer of Company D inquired whether Colonial was interested in discussing a potential sale of Colonial. Given the preliminary nature of Company D’s expression of interest, including the absence of a proposed price, price range or other specific terms in Company D’s January 29^th letter, as well as concerns regarding Company D’s ability to structure and complete an acquisition of Colonial, Colonial did not engage in further substantive discussions with Company D regarding a possible sale transaction at that time. On March 8, 2013, Colonial received an unsolicited joint letter from Company D and a private equity investment firm aligned with Company D, which letter expressed interest in exploring a potential all-cash acquisition of Colonial at a premium to Colonial’s then current stock price. The March 8th letter did not include a proposed price, price range or other specific terms of a potential transaction. As described further below, the Company D expression of interest was reviewed and considered by the Colonial Executive Committee on March 12, 2013.

During February 2013, Messrs. Bolton and Lowder spoke briefly by telephone and conveyed to each other that their respective companies had not considered a proposed strategic combination transaction of the companies since negotiations had ceased in late 2012.

On February 22, 2013, Mr. Lowder received an unsolicited telephone call from the chief financial officer of Company B, expressing Company B’s interest in a potential acquisition of Colonial in an all-cash transaction at a premium to Colonial’s then current stock price. The chief financial officer of Company B indicated that Company B would not involve third party partners in the transaction, and that Company B would have a preliminary price or price range to share with Colonial within a few weeks. In addition, Company B’s chief financial officer proposed that Company B and Colonial enter into a confidentiality agreement in order to proceed with negotiations for a potential transaction.

On February 26, 2013, Mr. Bolton sent a regular monthly update to the MAA Board regarding the possibility of increased REIT mergers and acquisitions activity generally and provided the MAA Board with an update on the conversation that Mr. Bolton had with Mr. Lowder.

On or about March 11, 2013, Mr. Lowder and another Colonial employee met over dinner with Mr. Bolton during an industry conference. During this dinner, Mr. Lowder and Mr. Bolton discussed certain matters related to the industry in general, but did not discuss the prior discussions between the two companies regarding a potential strategic combination transaction.

On March 12, 2013, the Colonial Executive Committee held a telephonic meeting with Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells present. During this meeting, Mr. Lowder discussed with the Colonial Executive Committee the various unsolicited inquiries received from third parties since January 2013, including the inquiries from Company D and Company B. In addition, Mr. Lowder reported on his dinner meeting with Mr. Bolton the previous evening. The Colonial Executive Committee members then engaged in a discussion regarding Colonial’s strategic direction and the expressions of interest from each of Company D and Company B. The Colonial Executive Committee members also engaged in a discussion regarding the differences between an all-cash sale transaction of the type proposed by Company D and Company B and a stock-for-stock business combination transaction of the type previously discussed with MAA. During this discussion, the legal advisors discussed with the Colonial Executive Committee certain fiduciary considerations pertaining to members of the Colonial Board when it receives an unsolicited expression of interest regarding a potential strategic combination transaction. BofA Merrill Lynch discussed with the Colonial Executive Committee, among other things, certain preliminary financial considerations with respect to Company D’s and Company B’s respective expressions of interest. Based on the preliminary nature of Company D’s expression of interest, as well as Colonial management’s familiarity with Company D and the private equity investment firm aligned with Company D, concerns regarding Company D’s ability to structure and complete an acquisition of Colonial, taking into account the private equity investment firm’s involvement, and the importance of certainty of closing and the ability to timely complete a transaction, the Colonial Executive Committee determined not to proceed with discussions with Company D at that time. Based on Colonial management’s familiarity and experience with Company B, particularly with respect to executing large, complex transactions, and views regarding Company B’s ability to structure and complete a transaction with Colonial, the Colonial Executive Committee authorized Mr. Lowder to inform Company B that it would need to submit its proposal in writing, and include a price and other material terms and details regarding equity and debt sources, timing and diligence requirements, if it was to be considered by the Colonial Board, noting that certainty of closing and the ability to move quickly to complete a transaction should be stressed to Company B. The Colonial Executive Committee also determined that, given that no written proposal had been submitted, Colonial would not, at that time, engage in negotiations with Company B regarding the terms of its expression of interest or enter into a confidentiality agreement or exchange non-public information with Company B.

On March 13, 2013, Mr. Lowder, together with representatives of BofA Merrill Lynch, spoke by telephone with the chief financial officer of Company B. Mr. Lowder informed the chief financial officer of Company B that it would need to submit its proposal in writing, and include a price and other material terms, including details regarding equity and debt sources, timing and diligence requirements, if it was to be considered by the Colonial Board. Mr. Lowder also stressed the importance of certainty of closing and the ability to quickly complete a transaction. The chief financial officer of Company B indicated that it intended to arrange for an insurance company to provide bridge financing, that Company B intended to fund 50% of the equity financing from an existing investment fund and involve several other third party investors to provide the remaining equity financing and that Company B was evaluating the existing covenants applicable to Colonial’s outstanding debt instruments to determine whether to seek to modify any of the covenants in connection with a potential transaction. The chief financial officer of Company B also stated that Company B would agree, in the event that Company B and Colonial ultimately entered into a definitive agreement for a sale transaction, to include in such definitive agreement a provision, commonly known as a “go shop” provision, that would allow Colonial an opportunity to engage in a post-signing effort to solicit higher bids from potential acquirors.

On March 28, 2013, Mr. Lowder received a letter from Company B expressing Company B’s interest in a potential acquisition of Colonial in an all-cash transaction. The letter proposed that Company B would acquire all of the outstanding Colonial common shares and all outstanding limited partner interests in Colonial LP for $26.00 per share, which represented a 15% premium to the closing price of Colonial common shares on March 26, 2013. The letter also noted that Company B intended to capitalize the transaction through a combination of equity (including roll-over equity from existing limited partners of Colonial LP), new mortgage debt and the assumption of Colonial’s existing debt, that existing limited partners of Colonial LP would have the option to roll-over their interests, in a transaction intended to constitute a tax-deferred exchange, into units of a reconstituted partnership or similar entity, and that Company B’s proposal was subject to satisfactory completion of diligence (for which Company B requested a 60-day exclusivity period) and negotiation and execution of definitive documentation. The letter did not address several of the significant terms and conditions discussed on March 13^th with Company B’s chief financial officer, including with respect to debt and equity sources or the inclusion of a “go shop” provision in definitive documentation.

On April 2, 2013, Mr. Lowder, together with representatives of BofA Merrill Lynch, spoke by telephone with the chief financial officer of Company B. At Mr. Lowder’s request, the chief financial officer of Company B provided additional information regarding certain aspects of Company B’s March 28^th letter, including with respect to Company B’s proposed debt and equity financing requirements and sources, Company B’s internal approval process, the proposed ultimate capital structure including Company B’s intention to engage a third party operator to manage Colonial’s properties, Company B’s lender due diligence requirements and timing. Company B’s chief financial officer noted that Company B had identified a private company to operate the Colonial properties, but had not engaged outside legal and financial advisors regarding a possible transaction with Colonial, and confirmed Company B’s willingness to include a “go shop” provision in the definitive transaction document relating to the acquisition.

On April 4, 2013, Mr. Lowder met with a representative of J.P. Morgan in Birmingham where they discussed the real estate capital markets generally, the asset sale environment, and the strategic transaction discussions between MAA and Colonial in late 2012. As part of that discussion, Mr. Lowder indicated that Colonial was moving forward with its current business strategy as a stand-alone company and, if MAA continued to have an interest in a strategic combination transaction with Colonial, it should indicate that interest.

On April 8, 2013, the Colonial Board held a telephonic meeting at which Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells were present. During this meeting, Mr. Lowder discussed with the Colonial Board the various unsolicited inquiries received from third parties since January 2013, including the inquiries from Company D and Company B and reported on the discussion of these unsolicited inquiries by the Colonial Executive Committee during its March 8^th meeting, including the Colonial Executive Committee’s reasons for deciding not to pursue discussions with Company D and to continue discussions with Company B. The Colonial Board then considered the following potential strategic alternatives: (1) continue to pursue Colonial’s existing business strategy as an independent, stand-alone company and not engage in any strategic transactions with any third parties; (2) continue to pursue Colonial’s existing business strategy as an independent, stand-alone company, but make certain adjustments to that business strategy to help further strengthen Colonial’s financial position, and not engage in any strategic transactions with any third parties; (3) explore a possible strategic combination transaction with MAA; or (4) explore a possible sale transaction with Company B or another third party. BofA Merrill Lynch discussed with the Colonial Board, among other things, certain preliminary financial considerations in connection with such potential strategic alternatives. During this discussion, the legal advisors discussed with the Colonial Board certain fiduciary considerations pertaining to members of the Colonial Board in the context of considering strategic combination transactions and sale transactions, including the differences between an all-cash sale transaction of the type proposed by Company D and Company B and a stock-for-stock business combination transaction of the type previously discussed with MAA. The Colonial Board also discussed the specific terms and conditions of Company B’s written expression of interest received on March 28^th, including the matters discussed on April 2^nd with Company B’s chief financial officer. Following this discussion, the Colonial Board authorized Mr. Lowder to continue preliminary discussions

regarding a potential transaction with Company B. The Colonial Board also authorized Mr. Lowder to contact MAA to determine whether MAA was interested in reengaging in discussions regarding a strategic combination transaction.

In addition, during the April 8, 2013 Colonial Board meeting, the Colonial Board established two separate committees with respect to consideration of a possible strategic transaction: (1) a transaction committee, herein referred to as the Colonial Transaction Committee, consisting of Messrs. T. Lowder, Bailey, Crawford and Spiegel, to help facilitate the exploration, evaluation and negotiation of possible strategic transactions; and (2) a separate committee, herein referred to as the Colonial Special Committee, consisting of the three trustees who did not own limited partner interests in Colonial LP—Messrs. Bailey, Crawford and Spiegel—to evaluate, oversee and negotiate, as necessary, any matters that may arise in connection with a strategic transaction which relate to the interests of limited partners in Colonial LP that are potentially not aligned with the interests of Colonial shareholders generally. The Colonial Board formed the Colonial Transaction Committee at this meeting to facilitate timely reaction and response to rapidly changing circumstances with multiple simultaneous discussions with MAA and Company B that may be more difficult to accomplish on a timely basis given the size of the full Colonial Board. The Colonial Board formed the Colonial Special Committee at this meeting given the uncertainty regarding potential conflicts that may arise depending on the actual transaction structure in the event the Colonial Board ultimately decided to pursue a strategic transaction.

Also on April 8, 2013, Mr. Bolton contacted Mr. Lowder by telephone to discuss reopening negotiations between MAA and Colonial regarding a potential strategic combination transaction.

On April 11, 2013, the MAA Board held a special telephonic meeting with members of senior management and representatives from J.P. Morgan, Goodwin Procter and Baker Donelson. Mr. Bolton summarized recent discussions between MAA and Colonial and provided an update on changes in share prices, financial guidance and third party net asset value analyses for MAA and Colonial. Representatives from J.P. Morgan then presented the MAA Board with an updated financial analysis for a proposed strategic transaction with Colonial (including, among other things, updated preliminary analyses reflecting changes in Colonial’s portfolio, including a number of asset sale transactions completed by Colonial) and an update on strategic and financial rationales for a potential combination. The MAA Board then discussed various issues, including, among others, potential exchange ratios as well as the due diligence review of Colonial being conducted. After the discussion, the MAA Board authorized the submission of a proposal to Colonial that provided for an exchange ratio of up to 0.360 of a share of MAA common stock per outstanding Colonial common share.

On April 12, 2013, Mr. Bolton contacted Mr. Lowder by telephone. During the course of such conversation, Mr. Lowder noted that Colonial had received an unspecified strategic transaction proposal or proposals.

Also on April 12, 2013, Mr. Bolton provided a written update to the MAA Board to summarize his conversation with Mr. Lowder. Mr. Bolton advised the MAA Board that MAA would submit a written proposal to Colonial with an exchange ratio of 0.360 of a share of MAA common stock per outstanding Colonial common share.

On April 13, 2013, Mr. Bolton delivered a non-binding proposal to Colonial providing, among other things, for an exchange ratio of 0.360 of a share of MAA common stock per outstanding Colonial common share, the retention of Messrs. Bolton and Campbell as Chairman and Chief Executive Officer and Chief Financial Officer, respectively, of the Combined Corporation, and a 30-day exclusivity period for negotiations between MAA and Colonial.

On April 16 and 17, 2013, the Colonial Transaction Committee held telephonic meetings at which Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells were present. During these meetings, Mr. Lowder provided an update on Colonial’s ongoing evaluation of Company B’s expression of interest. Mr. Lowder also reported on the receipt of a new proposal from MAA and his discussions with Mr. Bolton regarding that proposal. The Colonial Transaction Committee engaged in a discussion regarding the terms of

MAA’s proposal and Company B’s expression of interest and the advantages and disadvantages of the two types of transactions. This discussion included, among other items, a discussion regarding the length of the relative diligence periods requested by Company B and MAA, the relative price proposed by Company B compared to the implied value of Colonial’s common shares based on the MAA exchange ratio proposal, the likelihood that each of Company B and MAA could complete its proposed transaction in a timely manner, and the ability of Colonial shareholders to continue to participate in the future growth of the Combined Corporation if Colonial were to pursue a strategic combination transaction with MAA. The Colonial Transaction Committee discussed the significant additional timing likely involved in a transaction with Company B given the limited diligence conducted by Company B to date, that Company B had not yet hired outside legal or financial advisors and had relied on public information for purposes of formulating its latest expression of interest and the greater transaction execution risk associated with a transaction with Company B given the number of outside partners, the multiple layers of financing and the desire to engage a third party operator reflected in Company B’s expression of interest. During this discussion, the legal advisors discussed with the Colonial Transaction Committee members the Colonial Board member’s fiduciary duties in the context of considering the potential alternative transactions, including in the context of considering a stock-for-stock strategic combination and an all-cash sale transaction. The Colonial Transaction Committee also discussed the advantages and disadvantages of agreeing to exclusivity in the context of competing proposals, the potential impact on price negotiations resulting from additional diligence review during an exclusivity period, the risks associated with a lengthy diligence period and strategic considerations and appropriate timing for entering into exclusivity with a potential counterparty. The Colonial Transaction Committee also engaged in a discussion regarding the provisions included in MAA’s proposal, including the “force the vote” provision, the change of board recommendation provisions, and the circumstances in which a termination fee would be payable. Following these discussions, the Colonial Transaction Committee authorized Mr. Lowder to engage in additional discussions with Company B to seek to improve its proposed terms, including the proposed price, and obtain greater specificity regarding the terms of Company B’s proposal, including with respect to Company B’s debt and equity financing plans, as well as a shorter exclusivity period. The Colonial Transaction Committee also authorized Mr. Lowder to engage in additional discussions with MAA to seek to improve the exchange ratio and revise the composition of the Combined Corporation board to more closely reflect the relative ownership of MAA’s and Colonial’s shareholders in the Combined Corporation, as well as a shorter exclusivity period. The Colonial Transaction Committee requested that Mr. Lowder seek to obtain improved proposals from MAA and Company B in advance of Colonial’s regular, in person board and committee meetings on April 23-24, 2013 in Birmingham so that the Colonial Board would be in a position to consider and discuss such proposals from MAA and Company B.

On April 17, 2013, Mr. Lowder contacted Mr. Bolton by telephone. In response to MAA’s proposal from April 13, 2013, and based on the requests of the Colonial Transaction Committee, Mr. Lowder requested an increase in the exchange ratio, an increase in the number of proposed board members at the Combined Corporation for Colonial representatives and a shorter exclusivity period.

On April 18, 2013, Mr. Bolton provided a written update to the MAA Board summarizing the requests he received from Mr. Lowder on April 17, 2013.

On April 18, 2013, Mr. Lowder, together with representatives of BofA Merrill Lynch, spoke by telephone with the chief financial officer of Company B requesting that Company B improve its expression of interest, including the cash price, and submit a proposal with greater detail regarding the terms of Company B’s proposal. The chief financial officer of Company B indicated that he had communicated with several outside investors in Company B, without identifying Colonial, and had received indications of interest from such investors in providing 50% or more of the equity financing for a transaction. He also stated that Company B intended to use commercial bank financing to fund a portion of the acquisition and to arrange for financing from Freddie Mac post-closing to replace the commercial bank financing, that Company B would obtain a debt commitment letter if requested, and that an unaffiliated public company operator was interested in a joint venture arrangement with Company B to acquire Colonial, noting that the partner desired to acquire outright certain properties representing approximately 30% of Colonial’ existing multifamily portfolio. The chief financial officer of Company B

indicated that Company B would provide a more detailed written proposal on or prior to April 23, 2013. In several brief telephone conversations between a representative of BofA Merrill Lynch and the chief financial officer of Company B attempting to arrange this April 18^th discussion, the chief financial officer of Company B originally had suggested that the proposed price could be as high as $27.00 per share, but subsequently noted that the proposed price would be $26.50 per share because of, in the view of Company B’s investment committee, valuation considerations associated with certain land recorded on Colonial’s financial statements.

On April 22, 2013, the MAA Board held a special telephonic meeting with members of senior management. Mr. Bolton summarized his recent conversations with Mr. Lowder and the status of the discussions with Colonial. The MAA Board discussed responses to Colonial’s requests, including the exchange ratio, board composition of the Combined Corporation and exclusivity period. The MAA Board then authorized Mr. Bolton to respond to Colonial with the same exchange ratio of 0.360 of a share of MAA common stock per outstanding Colonial common share, a revised proposal on the composition of the board of the Combined Corporation and a request for a reduced exclusivity period of 21 days from the date on which substantially all due diligence materials were provided by Colonial.

Later on April 22, 2013, Mr. Bolton delivered to Mr. Lowder MAA’s response to Colonial’s requests from April 17, 2013. MAA responded that it would not agree to an increase to the exchange ratio above 0.360 of a share of MAA common stock per outstanding Colonial common share and proposed a revised board composition for the Combined Corporation along with a request for an exclusivity period of 21 days starting on the date on which substantially all due diligence materials were provided.

On April 23, 2013, Mr. Lowder received a letter and proposed term sheet from Company B’s chief financial officer. In the letter, Company B proposed to acquire all outstanding Colonial common shares and all outstanding limited partner interests in Colonial LP for $26.50 per share in cash, which represented a 15% premium to the closing price of Colonial common shares on April 22, 2013. The letter also noted that Company B intended to capitalize the transaction through a combination of equity (including roll-over equity from existing limited partners of Colonial LP), the inclusion of a joint venture partner, new mortgage debt and the assumption of Colonial’s existing debt, that existing limited partners of Colonial LP would have the option to roll-over their interests, in a transaction intended to constitute a tax-deferred exchange, into units of a reconstituted partnership or similar entity, and that Company B was requesting a 60-day exclusivity period to conduct diligence and negotiate definitive documentation. The letter noted that Company B’s proposal was not subject to a financing contingency. The term sheet received from Company B also noted that the transaction potentially could be structured to provide Colonial LP unitholders the option to exchange their units for those of another publicly traded REIT. The term sheet further noted that Company B’s proposed lender had given assurance that Colonial’s portfolio could be financed and that the lender was prepared to assist with bridge financing, that closing would be conditioned on, among other things, receipt of regulatory approvals and other standard conditions for Company B’s obligation to acquire a public company, that the definitive agreement would contain a 30-day “go shop” provision and that Company B was anticipating a shareholder vote and closing of the transaction on or before July 31, 2013. Company B also separately confirmed by e-mail to Mr. Lowder on April 23, 2013 that Company B’s joint venture partner would agree to issue units in its operating partnership if requested.

On April 23, 2013, the Colonial Transaction Committee met in person at Colonial’s headquarters in Birmingham, with Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells present (in person or telephonically). During this meeting, Mr. Lowder provided an update on the status of discussions with MAA and Company B. Mr. Lowder informed the Colonial Transaction Committee of the updated information and proposals received from MAA and Company B. The Colonial Transaction Committee engaged in a discussion regarding the terms of the two proposals. During this discussion, the legal advisors discussed with the Colonial Transaction Committee members the Board members’ fiduciary duties when considering a stock-for-stock strategic combination transaction and an all-cash sale transaction. Following this discussion, the Colonial Transaction Committee agreed to discuss the two proposals, and other potential strategic alternatives, with the Colonial Board at its board meeting on April 24, 2013.

On April 24, 2013, the Colonial Board held its regular, in person board meeting at Colonial’s headquarters in Birmingham with Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells present (in person or telephonically). During this meeting, Mr. Lowder updated the Colonial Board on the status of discussions with MAA and Company B and the terms of each of MAA’s and Company B’s latest proposals. In addition, BofA Merrill Lynch updated the Colonial Board with respect to financial matters. The Colonial Board also engaged in a discussion regarding the terms of the two proposals and the various considerations discussed by the Colonial Transaction Committee during its meetings on April 16, 17 and 23. With respect to the MAA proposal, the Colonial Board discussed, among other things, the strength of the MAA management team, MAA’s anticipated approach to Colonial’s development pipeline, potential synergies, timing considerations, and the proposed board composition of the Combined Corporation in light of the relative ownership of shareholders in the two companies and historical knowledge of the members of the Colonial Board of the current Colonial properties that would comprise a substantial portion of the Combined Corporation’s portfolio. With respect to Company B’s proposal, the Colonial Board discussed, among other things, that the price proposed by Company B was at a substantial premium to the then current Colonial share price, management’s belief that Company B was capable of executing a sale transaction of the type proposed, Company B’s willingness to arrange for a third party operator to provide a liquidity option to holders of limited partnership interests in Colonial LP who elect to roll-over their equity as contemplated in Company B’s term sheet. The Colonial Board also noted the less-developed nature of Company B’s proposal, the fact that Company B had not completed the same level of diligence as MAA and concerns of not being able to reach agreement on mutually acceptable terms with Company B with respect to a sale transaction due to matters outside Colonial’s and, in some cases outside Company B’s control, including the need for Company B to conduct diligence on Colonial, Company B’s need to obtain substantial third party equity and debt financing from multiple parties and the likely need for each provider of such equity and debt financing to conduct diligence on Colonial, and Company B’s intention to involve a joint venture partner which would require a separate negotiation. During this discussion, the legal advisors discussed with the Colonial Board the Colonial Board members’ fiduciary duties when considering a stock-for-stock strategic combination transaction and an all-cash sale transaction. The Colonial Board also discussed, with respect to each proposal, the risks associated with the pursuit of, but failure to consummate, a transaction, confidentiality considerations associated with a lengthy process, and the potential disruption to Colonial in the event of rumors and leaks and management’s distraction from continuing business activities, as well as the possibility of continuing discussions with both MAA and Company B, noting the difficulties with such approach given the separate requests for exclusivity. The Colonial Board also noted the importance of including appropriate flexibility in the definitive transaction agreement with either MAA or Company B to enable Colonial to respond to other bona fide acquisition proposals, including Company B’s willingness to include a “go shop” provision in the definitive transaction agreement, given the Colonial Board’s prior decision not to solicit proposals for other transactions due to the potential detrimental effects on Colonial’s business and the appropriateness of a mutual non-solicitation of competing transactions in a strategic combination transaction with MAA. Following this discussion and its evaluation of the two proposals, the Colonial Board authorized the Colonial Transaction Committee to continue negotiations with MAA and enter into exclusivity arrangements with MAA subject to MAA agreeing to a more balanced representation on the Combined Corporation board (based on the relative ownership of shareholders from the two companies) than that included in MAA’s last proposal and subject to MAA agreeing that Colonial board designees on the Combined Corporation board would be entitled to be re-nominated for at least two years following the combination to facilitate the integration and combination of the two companies.

On April 25, 2013, Mr. Lowder contacted Mr. Bolton by telephone. In response to Mr. Bolton’s proposal from April 22, 2013, Mr. Lowder indicated, on behalf of Colonial, that Colonial was prepared to agree to an exchange ratio of 0.360 of a share of MAA common stock per outstanding Colonial common share and a 21-day exclusivity period, but requested that the board of directors of the Combined Corporation consist of 12 directors, including seven directors from the MAA Board and five directors from the Colonial Board.

On April 26, 2013, Mr. Bolton provided a written update to the MAA Board. Mr. Bolton summarized his telephone call with Mr. Lowder from April 25, 2013, and explained that the Colonial Board was prepared to begin detailed diligence, subject to resolution of board composition matters.

Also on April 26, 2013, one of the independent trustees of the Colonial Board received an email from a business acquaintance inquiring whether Mr. Lowder was interested in speaking with a former employee of the business acquaintance. The Colonial Board member subsequently learned that the former employee was now employed by a party that previously had made an unsolicited verbal inquiry regarding a transaction to acquire Colonial. On May 5, 2013, the Colonial Board member responded by e-mail stating that he had passed along the e-mail inquiry to Mr. Lowder. Neither the business acquaintance nor the former employee contacted the Colonial Board member or Mr. Lowder further. Given the status of negotiations with MAA, and the non-solicitation provision included in the term sheet signed by Colonial and MAA on May 2, 2013, as discussed below, as well as the speculative nature of the inquiry, Mr. Lowder did not contact the former employee.

Later on April 26, 2013, the Colonial Transaction Committee held a telephonic meeting with Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells present. During this meeting, the Colonial Transaction Committee discussed the terms and conditions included in the non-binding term sheet included as part of MAA’s April 22^nd written proposal. Following discussion, the Colonial Transaction Committee authorized Mr. Lowder to prepare and deliver to MAA a written response to the terms and conditions included in the non-binding term sheet.

On April 29, 2013, at Colonial’s request, representatives from BofA Merrill Lynch separately contacted representatives from JP Morgan and Goodwin Procter regarding Colonial’s views with respect to the composition of the Combined Corporation’s board of directors.

Also on April 29, 2013, the MAA Board held a special telephonic meeting with members of senior management and representatives from J.P. Morgan, Goodwin Procter and Baker Donelson. The MAA Board discussed the board composition of the Combined Corporation, including the proposed number of directors of the Combined Corporation from the Colonial Board taking into account the negotiated exchange ratio of 0.360 of a share of MAA common stock per outstanding Colonial common share. The MAA Board then authorized Mr. Bolton to accept Colonial’s proposal that the Combined Corporation’s board of directors consist of no more than seven directors from the MAA Board and no more than five directors from the Colonial Board.

Later on April 29, 2013, Mr. Bolton delivered a revised proposal to Colonial, which provided for (i) an exchange ratio of 0.360 of a share of MAA common stock per outstanding Colonial common share, (ii) a board of directors for the Combined Corporation consisting of 12 members, with seven directors from the MAA Board and five directors from the Colonial Board, and (iii) a 21-day exclusivity period beginning on the execution date of a term sheet. Following the delivery of the revised proposal, Mr. Bolton contacted Mr. Lowder by telephone to discuss the proposed board composition of the Combined Corporation.

On or about April 29, 2013, Mr. Lowder left a voicemail message for Company B’s chief financial officer informing him that the Colonial Board had determined not to pursue at this time further discussions with Company B regarding a possible strategic sale transaction.

Also on April 30, 2013, at Colonial’s request, BofA Merrill Lynch delivered Colonial’s revised non-binding term sheet to MAA. The term sheet requested, among other things, (i) that each Colonial designee to the Combined Corporation’s board of directors serve for two years, (ii) removal of a “force the vote” provision, (iii) removal of a requirement for a party to pay the other party’s expenses if its shareholders failed to approve the transaction, and (iv) removal of a requirement for a party to advise the other party of the terms of any competing proposals received during the exclusivity period.

Also on May 1, 2013, J.P. Morgan delivered to Colonial, on behalf of MAA, a revised non-binding term sheet. The term sheet provided for, among other things, (i) a requirement that Colonial’s nominees to the Combined Corporation’s board of directors satisfy MAA’s existing corporate guidelines and code of business conduct and ethics, (ii) the reinstatement of the requirement for a party to pay the other party’s expenses if its shareholders failed to approve the transaction, and (iii) the reinstatement of the requirement for a party to advise the other party of the terms of any competing proposals received during the exclusivity period. The revised term sheet sent by J.P. Morgan did not contain a “force the vote” provision.

Later on May 1, 2013, at the request of MAA and Colonial, representatives of J.P. Morgan and BofA Merrill Lynch met telephonically to discuss certain matters relating to the term sheet circulated by J.P. Morgan earlier in the day, including the possibility that any new contractual arrangements intended to protect the income tax position of holders of limited partnership interests in Colonial LP, herein referred to as tax protection arrangements, may be requested for unitholders of Colonial LP in the strategic combination transaction and the requirement that a party would be required to advise the other party of the terms of any competing proposal during the exclusivity period.

On May 2, 2013, Mr. Bolton contacted Mr. Lowder telephonically to inquire whether any new tax protection arrangements would be requested for unitholders of Colonial LP in the strategic combination transaction.

Bolton and Campbell as the Chief Executive Officer and Executive Vice President and Chief Financial Officer, respectively, of the Combined Corporation, (v) a mutual non-solicitation provision with respect to competing transactions, (vi) payment of expenses by a party, up to a specified amount, if such party’s shareholders fail to approve the transaction, and (vii) a 21-day exclusivity period beginning on May 2, 2013.

The Colonial Special Committee also discussed MAA’s proposal that the existing limited partnership agreement of Colonial LP be used as the limited partnership agreement of the Combined Corporation’s operating partnership and tax protection arrangement structures generally. During this discussion, Hunton & Williams discussed with the Colonial Special Committee the members’ fiduciary duties under applicable law, the types of tax protection arrangements that could be provided to limited partners in an operating partnership and the tax protection arrangements, if any, provided in other merger transactions to limited partners in operating partnerships. Following discussion, the Colonial Special Committee determined that the mergers should be structured to provide that the limited partnership agreement for the Combined Corporation’s operating partnership contain substantially the same provisions as contained in the existing limited partnership agreement of Colonial LP including, in particular, for the benefit of limited partners in MAA LP after the partnership merger, the provision relating to Colonial LP’s consideration of the income tax considerations of limited partners of Colonial LP with respect to actions taken by the general partner of Colonial LP.

After a discussion by the MAA Board of various financial aspects of the proposed strategic transaction with Colonial and J.P. Morgan’s valuation analysis, J.P. Morgan delivered to the MAA Board an oral opinion, which was confirmed by the delivery of a written opinion dated June 1, 2013, to the effect that, as of that date and based on and subject to various assumptions and limitations described in its opinion, the exchange ratio provided for in the merger agreement was fair, from a financial point of view, to MAA. Following

these presentations and discussions, and other discussions and deliberations by the MAA Board concerning, among other things, the matters described below under “—Recommendation of the MAA Board and Its Reasons for the Parent Merger,” representatives of Goodwin Procter and Baker Donelson summarized the process for the approval of the transaction and the duties of the directors, following which, Mr. Bolton and representatives of Baker Donelson reviewed the resolutions for consideration by the MAA Board to approve the proposed strategic transaction with Colonial. The MAA Board then unanimously (i) determined that the merger agreement, the parent merger and the transactions contemplated by the merger agreement were advisable and in the best interests of MAA and its shareholders, (ii) approved the mergers, the merger agreement and the other transactions contemplated by the merger agreement, (iii) authorized and approved the issuance of shares of MAA common stock to the holders of Colonial common shares in the parent merger, (iv) directed that the merger agreement and the issuance of shares of MAA common stock be submitted for approval at a meeting of MAA shareholders, and (v) recommended the approval of the merger agreement and the issuance of shares of MAA common stock by MAA shareholders. In connection with the foregoing, the MAA Board also approved, among other things, the waivers to be given by certain MAA executives with respect to rights under existing employment agreements and equity awards, the preparation and filing of this joint proxy statement/prospectus, the engagement letter with J.P. Morgan, the amendment and restatement of the limited partnership agreement of MAA LP, and the preparation and mailing of a consent solicitation for holders of limited partnership units in MAA LP.

On June 1, 2013 and June 2, 2013, Goodwin Procter and Hogan Lovells exchanged drafts of the merger agreement, the disclosure schedules of both Colonial and MAA to the merger agreement and the amended and restated limited partnership agreement of MAA LP.

On June 2, 2013, the Colonial Board held a telephonic meeting, with Mr. Hardin and representatives of BofA Merrill Lynch and Hogan Lovells present. During this meeting, Colonial’s legal and financial advisors reviewed with the Colonial Board, among other things, legal and financial aspects of the proposed transaction with MAA. In addition, a representative of Hogan Lovells reviewed with the Colonial Board the material terms of the proposed merger agreement. Mr. Lowder then reviewed the strategic rationale and anticipated benefits of the proposed strategic combination transaction to Colonial shareholders. BofA Merrill Lynch then reviewed with the Colonial Board the financial terms of the proposed transaction and its financial analysis of the exchange ratio provided for in the parent merger and delivered to the Colonial Board an oral opinion, confirmed by delivery of a written opinion dated June 2, 2013, to the effect that, as of that date and based on and subject to various assumptions and limitations described in the opinion, the exchange ratio provided for in the parent merger was fair, from a financial point of view, to the holders of Colonial common shares. During this meeting, the Colonial Transaction Committee delivered its recommendation that the Colonial Board approve the merger agreement. Following these presentations and discussions, and other discussions by the Colonial Board concerning, among other things, the matters described below under “—Recommendation of the Colonial Board and Its Reasons for the Parent Merger,” the Colonial Board, by a unanimous vote of all trustees, (i) concluded that the merger agreement and the transactions contemplated thereby, including the parent merger and the partnership merger, were advisable and in the best interests of Colonial and its shareholders, (ii) approved and adopted the merger agreement and the plan of merger, (iii) directed that the merger agreement and the parent merger pursuant to the plan of merger be submitted for approval at a meeting of Colonial shareholders and (iv) recommended the approval of the merger agreement and the parent merger pursuant to the plan of merger by Colonial shareholders.

On the morning of June 3, 2013, MAA and Colonial executed and delivered the merger agreement and certain ancillary documents prior to the opening of the stock markets and issued a joint press release announcing the mergers and execution of the merger agreement.

Recommendation of the MAA Board and Its Reasons for the Parent Merger

In evaluating the parent merger, the MAA Board consulted with its legal and financial advisors and MAA’s management and, after careful consideration, the MAA Board unanimously determined and declared that the merger agreement, the parent merger and the other transactions contemplated by the merger agreement (including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger) are

advisable and in the best interests of MAA and its shareholders. The MAA Board unanimously adopted and approved the merger agreement, the parent merger and the other transactions contemplated by the merger agreement.

The MAA Board unanimously recommends that MAA shareholders vote FOR the proposal to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of shares of MAA common stock to Colonial shareholders in the parent merger.

In deciding to declare advisable and approve and adopt the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the issuance of the MAA common stock to the Colonial shareholders in connection with the parent merger, and to recommend that MAA shareholders vote to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, the MAA Board considered various factors that it viewed as supporting its decision, including the following material factors described below:

•

Strategic Benefits. The MAA Board expects that the parent merger will provide a number of significant potential strategic opportunities and benefits, including the following:

•

the combination of two highly complementary multifamily portfolios to create the preeminent Sunbelt-focused multifamily REIT and the second largest publicly-held owner and operator of multifamily units in the United States by number of units will allow MAA shareholders to participate in a stronger Combined Corporation with the opportunity to leverage both companies’ strong presence across the United States Sunbelt region and would result in a platform with superior value creation opportunities;

•

the combined portfolio of approximately 85,000 multifamily units in 285 properties would provide an enhanced competitive advantage across the Sunbelt region and drive opportunistic growth and capital deployment;

•

by combining two companies with businesses in complementary geographic regions, the Combined Corporation is expected to have improved diversification across large and secondary markets in the high-growth Sunbelt region, which will enhance the strength of the portfolio;

•

the combination of MAA and Colonial would more rapidly advance a number of strategic priorities underway at MAA, including, improving operating efficiencies, achieving more profitable scale, increasing assets in major and secondary Sunbelt markets and lowering capital costs to provide a stronger balance sheet;

•

the transaction is expected to create operational and general and administrative cost synergies that would drive higher margins primarily from the elimination of duplicative costs associated with supporting a public company platform and the leveraging of state of the art technology and systems, resulting in gross savings of approximately $25 million annually upon full integration, which is expected to occur over the 18–month period after closing of the mergers;

•

the Combined Corporation would be able to better serve the needs of its residents because of its larger geographic footprint and therefore increase its market share in high-growth Sunbelt markets;

•

as a result of its larger size, greater access to multiple forms of capital and an improved investment-grade rating with limited near-term debt maturities, the Combined Corporation is expected to have a lower cost of capital than MAA on a stand-alone basis and provide financial flexibility to capture opportunities across business cycles;

•

the Combined Corporation will provide improved liquidity for MAA shareholders as a result of the increased equity capitalization and the increased shareholder base of the Combined Corporation; and

•

the increased size and scale of the Combined Corporation is expected to produce operating cost advantages, enhance its ability to attract top talent, and strengthen the operating platform through integration of best practices from both companies, thereby allowing the Combined Corporation to be more competitive in the markets in which it operates.

•

Fixed Exchange Ratio. The MAA Board also considered that the fixed exchange ratio, which will not fluctuate as a result of changes in the market prices of shares of MAA common stock or Colonial common shares, provides certainty as to the respective pro forma percentage ownership of the Combined Corporation.

•

Superior Proposals. The MAA Board considered that, under certain circumstances, the merger agreement permits MAA, prior to the time MAA shareholders approve the parent merger, to consider and respond to an unsolicited bona fide alternative proposal or engage in discussions or negotiations with a third party making such a proposal if the MAA Board determines in good faith (after consultation with its outside legal counsel and financial advisors) that such alternative proposal constitutes or is reasonably likely to lead to a Superior Proposal and the MAA Board determines in good faith (after consultation with outside legal counsel) that the failure to take such action would be inconsistent with the directors’ exercise of their fiduciary obligations to the shareholders of MAA under applicable laws (see the section titled “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions” beginning on page 156).

•

Limited Ability to Change Recommendation. The MAA Board considered that the merger agreement, in circumstances not involving a Superior Proposal, permits the MAA Board to withhold, withdraw or modify its recommendation that MAA shareholders vote in favor of approval of the MAA merger proposal if a material development or change in circumstances occurs after June 3, 2013 and the MAA Board determines in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with the directors’ duties under applicable law (see the section titled “The Merger Agreement—Covenants and Agreements—No Solicitation of Transactions” beginning on page 156).

•

Opinion of Financial Advisor. The MAA Board considered the financial analyses presented to it by J.P. Morgan and J.P. Morgan’s oral opinion to the MAA Board, subsequently confirmed in writing, as to the fairness, from a financial point of view and as of the date of the opinion, to MAA of the exchange ratio pursuant to the merger agreement, which opinion was based on and subject to the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken as more fully described below in the section “Opinion of MAA’s Financial Advisor” beginning on page 97.

•

Familiarity with Businesses. The MAA Board considered its knowledge of the business, operations, financial condition, earnings and prospects of MAA and Colonial, taking into account the results of MAA’s due diligence review of Colonial, as well as its knowledge of the current and prospective environment in which MAA and Colonial operate, including economic and market conditions.

•

Governance. The MAA Board considered that the following governance arrangements would enable continuity of management and an effective and timely integration of the two companies’ operations:

•

seven of the twelve members of the board of directors of the Combined Corporation would be members of the MAA Board;

•

the Co-Lead Independent Directors for MAA would serve as Co-Lead Independent Directors for the Combined Corporation; and

•

the senior executives of MAA would serve as the senior executives of the Combined Corporation.

•

High Likelihood of Consummation. The MAA Board considered the commitment on the part of both parties to complete the mergers as reflected in their respective obligations under the terms of the merger agreement, and the likelihood that the third party and security holder approvals needed to complete the mergers would be obtained in a timely manner.

The MAA Board also considered a variety of risks and other potentially negative factors concerning the merger agreement, the parent merger and the other transactions contemplated by the merger agreement. These factors included:

•

the risk of diverting management focus and resources from operational matters and other strategic opportunities while working to implement the mergers;

•

that, under the terms of the merger agreement, MAA must pay Colonial a termination fee of $75 million and/or reimburse certain expenses incurred by Colonial in connection with the parent merger (up to $10 million) if the merger agreement is terminated under certain circumstances, which may deter other parties from proposing an alternative transaction that may be more advantageous to MAA shareholders, or which may become payable following a termination of the merger agreement in circumstances where no alternative transaction or superior proposal is available to MAA;

•

the terms of the merger agreement placing limitations on the ability of MAA to initiate, solicit or knowingly encourage or knowingly facilitate any inquiries or the making of any proposal or offer by or with a third party with respect to an Acquisition Proposal and to furnish non-public information to, or engage in discussions or negotiations with, a third party interested in pursuing an alternative business combination transaction;

•

the risk that, notwithstanding the likelihood of the parent merger being completed, the parent merger may not be completed, or that completion may be unduly delayed, including the effect of the pendency of the parent merger and the effect such failure to be completed may have on the trading price of MAA common stock and MAA’s operating results, particularly in light of the costs incurred in connection with the transaction

•

the risk that the anticipated strategic and financial benefits of the parent merger may not be realized or that the Combined Corporation may not achieve the forecasted net operating income or sales proceeds from the sale of certain of Colonial’s non-core and other assets;

•

the risk that the cost savings, operational synergies and other benefits to the holders of MAA common stock expected to result from the parent merger might not be fully realized or not realized at all, including as a result of possible changes in the real estate market or the multifamily industry affecting the markets in which the Combined Corporation will operate;

•

the risk of other potential difficulties in integrating the two companies and their respective operations;

•

the substantial costs to be incurred in connection with the transaction, including the transaction expenses arising from the mergers and the costs of integrating the businesses of MAA and Colonial;

•

the restrictions on the conduct of MAA’s business prior to the completion of the parent merger, which could delay or prevent MAA from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of MAA absent the pending completion of the parent merger;

•

that Colonial and MAA may be obligated to complete the parent merger without having obtained appropriate consents, approvals or waivers from, or successfully refinanced, the outstanding indebtedness of Colonial and MAA that requires lender consent or approval to consummate the parent merger, and the risk that such consummation could trigger the termination of, and mandatory prepayments of all amounts outstanding under, certain of MAA’s and Colonial’s indebtedness;

•

the existence of statutory dissenters’ rights for Colonial shareholders; and

•

other matters described under the section “Risk Factors” and “Cautionary Statement Concerning Forward-Looking Statements.”

This discussion of the information and factors considered by the MAA Board in reaching its conclusion and recommendations is not intended to be exhaustive and is not provided in any specific order or ranking. In view of the wide variety of factors considered by the MAA Board in evaluating the merger agreement and the transactions contemplated by it, including the parent merger, and the complexity of these matters, the MAA Board did not find it practicable to, and did not attempt to, quantify, rank or otherwise assign relative weight to those factors. In addition, different members of the MAA Board may have given different weight to different factors. The MAA Board did not reach any specific conclusion with respect to any of the factors considered and instead conducted an overall review of such factors and determined that, in the aggregate, the potential benefits considered outweighed the potential risks or possible negative consequences of approving the merger agreement, the parent merger and the other transactions contemplated by the merger agreement.

This explanation of the reasoning of the MAA Board and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section entitled “Cautionary Statement Concerning Forward-Looking Statements.”

Recommendation of the Colonial Board and Its Reasons for the Parent Merger

By vote at a meeting held on June 2, 2013, and based in part on the unanimous recommendation of the transaction committee of the Colonial Board, the Colonial Board unanimously (i) determined that the parent merger (including the plan of merger) and the other transactions contemplated by the merger agreement are advisable and in the best interests of Colonial and its shareholders, (ii) approved and adopted the merger agreement and the plan of merger, (iii) directed that a proposal to approve and adopt the merger agreement and the parent merger pursuant to the plan of merger be submitted for consideration at a meeting of Colonial’s shareholders and (iv) recommended the approval and adoption of the merger agreement and parent merger pursuant to the plan of merger by Colonial’s shareholders. The Colonial Board unanimously recommends that Colonial shareholders vote FOR the proposal to approve and adopt the merger agreement, the parent merger pursuant to plan of merger and the other transactions contemplated by the merger agreement, FOR the proposal to approve, on an advisory (non-binding) basis, the compensation payable to certain executive officers of Colonial in connection with the parent merger and FOR the proposal to approve one or more adjournments of the Colonial special meeting, if necessary or appropriate, including adjournments to permit further solicitation of proxies in favor of approval and adoption of the merger agreement and the parent merger pursuant to the plan of merger.

In evaluating the parent merger, the Colonial Board consulted with Colonial’s management and outside legal and financial advisors. In deciding to declare advisable and approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, and to recommend that Colonial’s shareholders vote to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, the Colonial Board considered various factors that it viewed as supporting its decision, including the material factors described below.

•

Strategic Benefits. Discussions with Colonial management regarding Colonial’s business, financial condition, results of operations, competitive position, business strategy, strategic options and prospects, as well as the risks involved in achieving these prospects, the nature of Colonial’s business and the industry in which it competes, and current industry, economic and market conditions, both on a historical and on a prospective basis, which led the Board to conclude that the alternative of continuing as a stand-alone company was less favorable to the Colonial shareholders than the parent merger and that the parent merger will provide a number of significant potential strategic opportunities and benefits, including the following:

•

the combination of Colonial’s and MAA’s highly complementary multifamily portfolios to create the pre-eminent Sunbelt focused multifamily REIT and the second largest publicly-held owner and operator of multifamily units in the United States by number of units will allow Colonial shareholders to participate in a stronger Combined Corporation with the opportunity to leverage both companies’ strong presence across the United States Sunbelt region and would result in a platform with superior value creation opportunities;

•

as a result of its larger size, greater access to multiple forms of capital and improved investment grade debt rating with limited near-term debt maturities, the Combined Corporation is expected to have a lower cost of capital than Colonial on a stand-alone basis and provide financial flexibility to capture opportunities across business cycles;

•

the combination of the two companies would more rapidly advance Colonial’s existing strategic priorities to grow its multifamily portfolio and strengthen its balance sheet;

•

the Combined Corporation is expected to benefit from Colonial’s development pipeline and internal development capabilities;

•

the transaction is expected to create operational and general and administrative cost synergies that would drive higher margins primarily from the elimination of duplicative costs associated with supporting a public company platform and the leveraging of state of the art technology and systems, resulting in gross savings of approximately $25 million annually, which is expected to occur over the 18-month period after closing of the mergers; and

•

by creating one of the largest U.S. multifamily REITs by number of units and, based on current market prices, one of the largest publicly traded U.S. multifamily REITs by enterprise value, the merger is expected to enhance the Combined Corporation’s ability to execute large, accretive transactions and facilitate opportunistic growth and capital deployment.

•

MAA’s Business, Operating Results, Financial Condition and Management. The Colonial Board considered information with respect to the business, operating results and financial condition of MAA, on both a historical and prospective basis, including MAA’s stable operating performance, lower leverage and the lower volatility of its stock price over the past 10 years, the quality, breadth and experience of MAA’s senior management team, and the similarities in the cultures of, and complimentary markets served by, the two companies, as well as the Colonial Board’s knowledge of the current and prospective environment in which the two companies operate, including economic and market conditions.

•

Continued Operation as a Stand-Alone Company. The Colonial Board evaluated, as an alternative to the parent merger, the potential rewards and risks associated with the continued execution of Colonial’s strategic plan as an independent company. In evaluating Colonial’s historical results and prospects for growth, the Colonial Board noted Colonial’s success in maintaining high occupancy rates, executing on Colonial’s asset recycling program, strengthening Colonial’s balance sheet, increasing Colonial’s focus on the multifamily business, successfully exiting from several joint ventures, and reducing overhead costs. The Colonial Board reviewed Colonial’s historical and possible future performance in light of the risks affecting its business, operations and financial condition, including the risks discussed in this joint proxy statement/prospectus under “Risk Factors—Risks Relating to the Mergers.” The Colonial Board also considered, among other factors, the challenges of continuing to operate independently, current market and industry trends, and the risks affecting Colonial’s ability to compete effectively against other competitors in the industry.

•

Merger Consideration. The Colonial Board evaluated the value of the merger consideration based on the then-current market price and historic trading price of MAA common stock, as well as various factors bearing on the quality and potential long-term value of the MAA common stock to be received as consideration, including the greater liquidity of the stock in the Combined Corporation. The Colonial Board noted that, based on the closing prices of the MAA common stock and Colonial common shares on May 31, 2013, which was the last trading day before the meeting of the Colonial Board at which the Colonial Board approved the merger agreement, the merger consideration had an implied value of $24.47 per Colonial common share, which represented approximately a 10.7 percent premium to the closing price of the Colonial common shares on May 31, 2013. The Colonial Board also noted that the implied per share merger consideration represented a premium to the Colonial price per share of approximately 13.7 percent over the one-week period before May 31, 2013, and approximately 16.3 percent over the one-month period before May 31, 2013. The Colonial Board also took into account that the fixed exchange ratio, which will not fluctuate as a result of changes in the market prices of Colonial common shares or shares of MAA common stock, provides certainty as to the respective pro forma percentage ownership of the Combined Corporation and that a decrease in the market price of Colonial common shares before the parent merger closing would not provide MAA with a right to terminate the merger agreement.

•

Dividend Rate. The Colonial Board considered that, based on the current dividend rates of Colonial and MAA, Colonial shareholders would see an approximately 19 percent increase in the dividend rate immediately after the closing, assuming no change in MAA’s current dividend rate.

•

Ownership in the Combined Corporation. The Colonial Board considered that, as of the closing, Colonial shareholders would own approximately 44% of the Combined Corporation assuming the conversion to shares of Combined Corporation common stock of all MAA LP limited partnership units issued to Colonial LP unitholders in the partnership merger and, as a result, the combination will allow Colonial shareholders to participate in the future growth and value creation of the Combined Corporation and to share pro rata in the benefits of the expected synergies.

•

Opinion of Financial Advisor. The Colonial Board considered the opinion, dated June 2, 2013, of BofA Merrill Lynch to the Colonial Board as to the fairness, from a financial point of view and as of such date, to the holders of Colonial common shares of the exchange ratio provided for in the parent merger, which opinion was based on and subject to the assumptions made, procedures followed, factors considered and limitations on the review undertaken as more fully described in the section entitled “Opinion of Colonial’s Financial Advisor.”

•

Tax-Free Transaction. The Colonial Board considered the expectation that the parent merger will generally qualify as a tax-free transaction for U.S. federal income tax purposes to Colonial shareholders that are U.S. holders.

•

Governance. The Colonial Board considered that the board of directors of the Combined Corporation would consist of twelve directors, five of whom will be chosen by the Colonial Board, which would facilitate an effective and timely integration of the two companies’ operations.

•

Likelihood of Consummation. The Colonial Board considered the commitment on the part of both parties to complete the mergers as reflected in their respective obligations under the terms of the merger agreement, and the likelihood that the third party and security holder approvals needed to complete the mergers would be obtained in a timely manner.

•

Terms and Conditions of the Merger Agreement. The Colonial Board considered the terms and conditions of the merger agreement, including:

•

Colonial’s ability, under certain circumstances, prior to the time Colonial shareholders approve the parent merger, to consider and respond to an unsolicited bona fide alternative proposal or engage in discussions or negotiations with the third party making such a proposal if the Colonial Board determines in good faith (after consultation with its outside legal counsel and financial advisors) that such alternative proposal either constitutes a Superior Proposal or is reasonably likely to lead to a superior proposal and the Colonial Board shall have determined in good faith (after consultation with outside legal counsel) that the failure to take such action would be inconsistent with the trustees’ exercise of their fiduciary obligations to the shareholders of Colonial under applicable laws;

•

Colonial’s ability, under certain circumstances, to terminate the merger agreement in order to enter into an agreement providing for a Superior Proposal, provided that Colonial complies with its obligations relating to the entering into of any such agreement and immediately prior to or concurrently with the termination of the merger agreement pays a termination fee of $75 million and reimburses MAA for expenses (up to $10 million), which the Colonial Board concluded was reasonable in the context of termination fees payable in comparable transactions and in light of the overall structure of the transaction and terms of the merger agreement, including the merger consideration;

•

the ability of the Colonial Board, under certain circumstances not involving a Superior Proposal, to withhold, withdraw or modify its recommendation that Colonial shareholders vote in favor of approval and adoption of the merger agreement and the parent merger pursuant to the plan of merger and terminate the merger agreement upon payment of a termination fee of $75 million and reimbursement of MAA for expenses (up to $10 million);

•

the fact that the merger agreement permits Colonial to continue to pay its regular quarterly cash dividend, in an amount not to exceed $0.21 per Colonial common share per quarter, as well as distributions in respect of units held in Colonial LP;

•

the fact that the merger agreement would provide Colonial with sufficient operating flexibility for it to conduct its business in the ordinary course of business consistent with past practice between the signing of the merger agreement and the completion of the parent merger; and

•

the fact that consent, approval or refinancing of Colonial’s existing indebtedness and most of MAA’s existing indebtedness is not a condition to completion of the parent merger.

•

Treatment of Holders of Limited Partner Interests in Colonial LP. The Colonial Board considered that, pursuant to the terms of the merger agreement, holders of limited partner interests in Colonial LP will receive 0.360 of a limited partner interest in MAA LP, in the partnership merger, which is the same as the exchange ratio in the parent merger. In addition, the Colonial Board considered that, consistent with the direction of the Colonial Special Committee, the limited partnership agreement of MAA LP will be amended to be in substantially the same form as the limited partnership agreement of Colonial LP currently in effect, and will retain, for the benefit of all limited partners in MAA LP after the partnership merger, the provision relating to Colonial LP’s consideration of the income tax considerations of limited partners of Colonial LP with respect to actions taken by the general partner of Colonial LP.

•

Dissenters’ Rights. The Colonial Board considered the fact that Colonial shareholders will have the right to exercise dissenters’ rights, as described in the section entitled “Dissenters’ Rights” beginning on page 173.

Alternative Transactions. The Colonial Board also considered, as alternatives to the parent merger or to continued independent operations, Colonial’s prospects for a merger or sale transaction with a company other than MAA and the potential terms for such other transactions. After taking into account the possible detrimental effects on Colonial’s business, including such effects on, among other things, its employees, tenants, customers, financing sources and business prospects, the Colonial Board determined not to solicit proposals for other transactions, whether a merger or sale, through an auction process or otherwise. The Colonial Board’s consideration of potential alternatives to the parent merger was informed by, among other matters, its familiarity with the various indications of interest and preliminary discussions involving potential transaction partners communicated from time to time, including the unsolicited inquiries received from Company B and Company D and described in this joint proxy statement/prospectus under “The Parent Merger—Background of the Mergers.” The Colonial Board concluded that the MAA merger, as compared to potential alternative transactions, would be in the best interests of Colonial’s shareholders in light of the overall terms of the MAA merger and the timing, likelihood and risks of completing alternative transactions, including the business, competition, industry and market risks that would apply to Colonial.

In particular, in deciding to approve the merger agreement, rather than to attempt to pursue a transaction with Company B on the basis of Company B’s written proposal received in April 2013, the Colonial Board considered the following material factors:

•

the Colonial Board’s determination, based on its consideration of the business, strategic plan, operating results, and management team of the Combined Corporation, as well as cost synergies and other strategic benefits of a transaction with MAA described above, that it was in the best interests of the Colonial shareholders for Colonial to pursue a transaction with MAA, offering Colonial shareholders the prospect of continued participation in the long-term value creation of the Combined Corporation, rather than pursue an all-cash sale transaction with Company B at the all-cash price included in Company B’s proposal;

•

the less developed nature of Company B’s proposal and the risk of not being able to reach agreement on mutually acceptable terms with Company B with respect to a sale transaction due to, among other things:

•

the need for Company B to conduct diligence on Colonial (which had not yet been initiated);

•

the need for Company B to obtain substantial equity and debt financing, including from third party sources, which would be expected to conduct their own separate diligence investigation of Colonial;

•

the increased risk of information leaks and other significant adverse effects on Colonial, including on its personnel and operations, due to the larger number of third parties that would be involved in a lengthy diligence evaluation of Colonial and the distractions during the pendency of the multi-party diligence process;

•

the need to negotiate specific merger terms and the related definitive agreement, including (i) additional issues arising from the terms included in Company B’s written proposal, such as financing matters, closing conditions, and the termination provisions, and (ii) other matters not addressed in Company B’s written proposal, such as consequences of Company B’s failure to obtain the requisite third party financing or refusal to close the transaction after it signs a definitive agreement, including negotiation of remedies in certain circumstances if Company B failed or refused to complete the transaction; and

•

the additional complexity associated with Company B’s intention to negotiate with and retain a third party operator as a partner to operate Colonial properties, as well as the third party operator’s desire to acquire specific properties of Colonial.

•

uncertainty regarding the final all-cash purchase price to be offered by Company B and the concern, given that Company B’s all-cash purchase price proposal was based on only publicly available information, that the all cash price would be reduced during the diligence and negotiation process, particularly in light of the fact that, based on statements by the Company B chief financial officer in April 2013, the all-cash price of $26.50 had already been reduced by Company B’s investment committee based on valuation considerations associated with certain land recorded on Colonial’s financial statements, as discussed above under “The Parent Merger—Background of the Mergers”;

•

that, given the need for third party financing, a transaction with Company B would involve greater risk that the ability of the parties to complete the transaction on the terms negotiated may be adversely affected due to adverse market conditions or economic or other events outside the control of the parties, which would increase the risk that a closing may not ultimately occur on the terms negotiated with Company B or at all;

•

that, as discussed above, the provisions of the merger agreement with MAA would permit Colonial, under certain circumstances, to terminate the merger agreement in order to enter into an agreement providing for a superior proposal, provided that Colonial (i) complies with its obligations relating to the entering into of any such agreement and (ii) immediately prior to or concurrently with the termination of the merger agreement pays a termination fee of $75 million and reimburses MAA for expenses (up to $10 million); and

•

the risk that, during the time needed for Company B to finalize and present a final offer, including the time necessary to conduct diligence and assemble equity and debt financing and negotiate with a third party operator, the proposed transaction with MAA may no longer be available.

The Colonial Board also considered a variety of risks and other potentially negative factors concerning the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, including the following material factors:

•

that, following completion of the parent merger, Colonial would no longer exist as an independent public company and Colonial’s shareholders would be able to participate in any future earnings growth of Colonial solely through their ownership of MAA common stock;

•

the risk that, notwithstanding the likelihood of the parent merger being completed, the parent merger may not be completed, including the effect of the pendency of the parent merger and the effect such failure to be completed may have on:

•

the trading price of Colonial common shares;

•

Colonial’s operating results, particularly in light of the costs incurred in connection with the transaction; and

•

Colonial’s ability to attract and retain key personnel, tenants, suppliers and customers;

•

that, under the terms of the merger agreement, Colonial must pay MAA a termination fee of $75 million and/or reimburse certain expenses incurred by MAA in connection with the parent merger (up to $10 million) if the merger agreement is terminated under certain circumstances, which may deter other parties from proposing an alternative transaction that may be more advantageous to Colonial shareholders, or which may become payable following a termination of the merger agreement in circumstances where no alternative acquisition agreement or superior proposal is available to Colonial;

•

the risk that, although the terms of the merger agreement would permit Colonial, until approval of the parent merger by its shareholders, to furnish non-public information to, or engage in discussions or negotiations with, third parties making unsolicited acquisition proposals that the Colonial Board determines are reasonably likely to lead to a superior proposal and to terminate the merger agreement to accept a superior proposal, subject to payment to MAA of a termination fee of $75 million and reimbursement of expenses (up to $10 million), other potential bidders may choose not to make an alternative transaction proposal and that, historically, the incidence of such superior proposals are relatively rare;

•

that the terms of the merger agreement place limitations on the ability of Colonial to initiate, solicit or knowingly encourage or knowingly facilitate any inquiries or the making of any proposal or offer by or with a third party with respect to an acquisition proposal;

•

the risk that MAA may receive a superior proposal and terminate the merger agreement upon payment of a termination fee to Colonial of $75 million plus reimbursement of expenses incurred by Colonial (up to $10 million) in accordance with the terms of the merger agreement;

•

that, if the parent merger does not close, Colonial’s employees will have expended extensive time and efforts to attempt to complete the transaction and will have experienced significant distractions from their work during the pendency of the transaction;

•

the possibility that the parent merger may not be completed, or that completion may be unduly delayed, for reasons beyond the control of Colonial or MAA, including because Colonial shareholders and/or MAA shareholders may not approve the parent merger and the other transactions contemplated by the merger agreement, because approval of the unitholders of MAA LP may not be obtained, or because the required third party consents may not be obtained;

•

that Colonial is not permitted to terminate the merger agreement solely because of changes in the market price of MAA common stock and the risk that, because the merger consideration is MAA common stock and the exchange ratio is fixed, Colonial shareholders may be adversely affected by any decrease in the trading price of MAA common stock between the announcement of the transaction and the completion of the parent merger, which would not have been the case had the consideration been based solely on a fixed value (that is, a fixed dollar amount of value per share in all cases);

•

the risk that the cost savings, operational synergies and other benefits to the holders of Colonial common shares expected to result from the parent merger might not be fully realized or not realized at all, including as a result of possible changes in the real estate market or the multifamily industry affecting the markets in which the Combined Corporation will operate or as a result of potential difficulties integrating the two companies and their respective operations;

•

the restrictions on the conduct of Colonial’s business prior to the completion of the parent merger, which could delay or prevent Colonial from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of Colonial absent the pending completion of the parent merger;

•

that Colonial and MAA may be obligated to complete the parent merger without having obtained appropriate consents, approvals or waivers from, or successfully refinanced, the outstanding

indebtedness of Colonial and MAA that requires lender consent or approval to consummate the parent merger, and the risk that such consummation could trigger the termination of, and mandatory prepayments of all amounts outstanding under, certain of MAA’s and Colonial’s indebtedness;

•

that, if the Colonial Board had determined to pursue a sale of the company and engaged in negotiations with a third party, including Company B, and reached agreement on the terms of a definitive sale transaction with such third party, the all-cash per share purchase price potentially could have been superior to the value of the merger consideration to be received by Colonial shareholders in the strategic combination merger with MAA;

•

that certain of Colonial’s trustees and executive officers have certain interests in the parent merger that might be different from the interests of Colonial’s shareholders generally as described under the section entitled “The Parent Merger—Interests of Colonial’s Trustees and Executive Officers in the Mergers” beginning on page 116; and

•

the substantial costs to be incurred in connection with the transactions, including the transaction expenses arising from the mergers and the costs of integrating the businesses of Colonial and MAA.

This discussion of the information and factors considered by the Colonial Board in reaching its conclusion and recommendations is not intended to be exhaustive and is not provided in any specific order or ranking. In view of the wide variety of factors considered by the Colonial Board in evaluating the merger agreement and the transactions contemplated by it, including the parent merger, and the complexity of these matters, the Colonial Board did not find it practicable to, and did not attempt to, quantify, rank or otherwise assign relative weight to those factors. In addition, different members of the Colonial Board may have given different weight to different factors. The Colonial Board did not reach any specific conclusion with respect to any of the factors considered and instead conducted an overall review of such factors and determined that, in the aggregate, the potential benefits considered outweighed the potential risks or possible negative consequences of approving the merger agreement.

THE COLONIAL BOARD UNANIMOUSLY RECOMMENDS THAT COLONIAL SHAREHOLDERS VOTE FOR THE PROPOSAL TO APPROVE AND ADOPT THE MERGER AGREEMENT, THE PARENT MERGER PURSUANT TO THE PLAN OF MERGER AND THE OTHER TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT, FOR THE ADVISORY VOTE ON EXECUTIVE COMPENSATION PROPOSAL AND FOR THE PROPOSAL TO ADJOURN.

The explanation of the reasoning of the Colonial Board and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section entitled “Cautionary Statement Concerning Forward-Looking Statements” beginning on page 43.

Opinion of MAA’s Financial Advisor

Pursuant to an engagement letter dated May 31, 2013, MAA retained J.P. Morgan as its financial advisor in connection with the parent merger.

At the meeting of the MAA Board on June 1, 2013, J.P. Morgan rendered its oral opinion to the MAA Board that, as of such date and based upon and subject to the factors and assumptions set forth in its opinion, the exchange ratio in the parent merger was fair, from a financial point of view, to MAA. J.P. Morgan has confirmed its June 1, 2013 oral opinion by delivering its written opinion to the MAA Board, dated June 1, 2013, that, as of such date, the exchange ratio in the parent merger was fair, from a financial point of view, to MAA. No limitations were imposed by the MAA Board upon J.P. Morgan with respect to the investigations made or procedures followed by it in rendering its opinions.

The full text of the written opinion of J.P. Morgan dated June 1, 2013, which sets forth the assumptions made, matters considered and limits on the review undertaken, is attached as Annex F to this joint proxy statement/prospectus and is incorporated herein by reference. You are urged to read the opinion in its entirety. J.P. Morgan’s written opinion is addressed to the MAA Board, is directed only to

the exchange ratio in the parent merger and does not constitute a recommendation to any shareholder of MAA as to how such shareholder should vote at the MAA special meeting. The summary of the opinion of J.P. Morgan set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of such opinion.

In arriving at its opinions, J.P. Morgan, among other things:

•

reviewed a draft dated May 31, 2013 of the merger agreement;

•

reviewed certain publicly available business and financial information concerning MAA and Colonial and the industries in which they operate;

•

compared the financial and operating performance of MAA and Colonial with publicly available information concerning certain other companies J.P. Morgan deemed relevant and reviewed the current and historical market prices of shares of MAA common stock and Colonial common shares and certain publicly traded securities of such other companies;

•

reviewed certain internal financial analyses and forecasts prepared by the management of MAA and used by J.P. Morgan at the direction of the management of MAA, relating to the respective businesses of MAA and Colonial, as well as the estimated amount and timing of cost savings and related expenses and synergies expected to result from the parent merger; and

•

performed such other financial studies and analyses and considered such other information as J.P. Morgan deemed appropriate for the purposes of its opinion.

J.P. Morgan also held discussions with certain members of the management of MAA and Colonial with respect to certain aspects of the parent merger, and the past and current business operations of MAA and Colonial, the financial condition and future prospects and operations of MAA and Colonial, the effects of the parent merger on the financial condition and future prospects of MAA, and certain other matters J.P. Morgan believed necessary or appropriate to its inquiry.

J.P. Morgan relied upon and assumed, without assuming responsibility or liability for independent verification, the accuracy and completeness of all information that was publicly available or was furnished to or discussed with J.P. Morgan by MAA and Colonial or otherwise reviewed by or for J.P. Morgan. J.P. Morgan did not conduct and was not provided with any valuation or appraisal of any assets or liabilities (including real estate assets and liabilities), nor did J.P. Morgan evaluate the solvency of MAA or Colonial under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to it or derived therefrom, including the synergies referred to above, J.P. Morgan assumed that they were reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management of MAA and Colonial, as applicable, as to the expected future results of operations and financial condition of MAA and Colonial to which such analyses or forecasts relate. J.P. Morgan expressed no view as to such analyses or forecasts (including the synergies) or the assumptions on which they were based. J.P. Morgan also assumed for United States federal income tax purposes that the partnership merger will qualify as and constitute a tax-free “assets-over” form of merger governed by Treasury Regulations Section 1.708-1(c)(3)(i) and the parent merger will qualify as a tax-free reorganization, and in each case will be consummated as described in the merger agreement and this joint proxy statement/prospectus, and that the definitive merger agreement would not differ in any material respect from the draft thereof provided to J.P. Morgan. J.P. Morgan is not a legal, regulatory or tax expert and relied on the assessments made by advisors to MAA with respect to such issues. J.P. Morgan further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the parent merger will be obtained without any adverse effect on MAA or Colonial or on the contemplated benefits of the parent merger.

The projections furnished to J.P. Morgan for MAA and Colonial were prepared by the management of MAA and used by J.P. Morgan at the direction of the management of MAA. MAA does not publicly disclose internal management projections of the type provided to J.P. Morgan in connection with J.P. Morgan’s analysis of the parent merger, and such projections were not prepared with a view toward public disclosure. These projections

were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of management, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such projections. For more information on the projections provided to J.P. Morgan, see “—Certain MAA Unaudited Prospective Financial Information” beginning on page 111 and “—Certain Colonial Unaudited Prospective Financial Information” beginning on page 113.

J.P. Morgan’s opinion is based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of, the date of such opinion. Subsequent developments may affect J.P. Morgan’s written opinion dated June 1, 2013, and J.P. Morgan does not have any obligation to update, revise, or reaffirm such opinion. J.P. Morgan’s opinion is limited to the fairness, from a financial point of view, of the exchange ratio in the parent merger, and J.P. Morgan has expressed no opinion as to the fairness of the parent merger to, or any consideration of, the holders of any class of securities, creditors or other constituencies of MAA or the underlying decision by MAA to engage in the parent merger. J.P. Morgan expressed no opinion as to the price at which shares of MAA’s common stock or Colonial’s common shares will trade at any future time, whether before or after the closing of the parent merger.

In accordance with customary investment banking practice, J.P. Morgan employed generally accepted valuation methods in reaching its opinion. The following is a summary of the material financial analyses utilized by J.P. Morgan in connection with providing its opinion.

Public Trading Multiples. Using publicly available information, including published equity research analysts’ estimates of Funds From Operations, which we refer to as FFO, per share and Adjusted Funds From Operations, which we refer to as AFFO, per share for calendar year 2014, which we refer to as CY14, J.P. Morgan analyzed certain trading multiples of other selected publicly traded REITs. None of the selected REITs are identical to MAA or Colonial. However, the selected REITs were chosen because they are publicly traded REITs with operations that, for purposes of the analysis of J.P. Morgan, may be considered similar to those of MAA and Colonial, including primarily the ownership of multifamily real estate.

For each of the selected REITs, J.P. Morgan calculated the multiple of equity market price per share to the median estimate of CY14 FFO per share and AFFO per share, as reported by equity research analysts as of May 30, 2013. J.P. Morgan also calculated the same trading multiples for MAA and Colonial based on equity research analyst data and data provided by MAA management. In J.P. Morgan’s view, the FFO and AFFO metrics used by equity research analysts and MAA management were sufficiently similar so as not to materially affect this analysis.

The following presents the results of this analysis:


Consensus equity research estimates	Price / FFO per Share Multiple CY14		Price / AFFO per Share Multiple CY14
UDR, Inc.		16.4x		18.6x
Camden Property Trust		16.1x		19.0x
Essex Property Trust, Inc.		19.1x		20.9x
BRE Properties, Inc.		19.4x		21.5x
Home Properties, Inc.		13.1x		14.8x
Post Properties, Inc.		17.3x		19.8x
MAA		13.2x		15.1x
Colonial		14.7x		18.3x


Management estimates	Price / FFO per Share Multiple CY14		Price / AFFO per Share Multiple CY14
MAA		13.2x		15.2x
Colonial		16.0x		18.0x

J.P. Morgan also calculated the trading multiples above for Colonial taking into account adjustments for $217 million of assets under letters of intent or recently completed property divestitures and $108 million for the value of land. Factoring in these adjustments, the Colonial CY14 FFO and AFFO per share would be 12.4x and 15.5x, respectively, based on equity research estimates, and 13.6x and 15.3x, respectively, based on MAA management estimates.

Based on the above analysis and other factors J.P. Morgan considered appropriate, J.P. Morgan then applied a multiple reference range of 13.0x to 16.0x for CY14 FFO per share and 15.0x to 19.0x for CY14 AFFO per share. The analysis indicated the following equity values per share of MAA common stock and Colonial common share.


	Equity value per MAA share		Equity value per Colonial share
Price / CY14 FFO per share multiple	$	66.80 – $82.20	$	21.50 – $25.70
Price / CY14 AFFO per share multiple	$	66.90 – $84.80	$	22.00 – $27.00

Net Asset Value Analysis. J.P. Morgan prepared a per share net asset value analysis for MAA using 2013 estimated cash net operating income and asset and liability balances as of March 31, 2013. Capitalization rate ranges varied by property based on the type of property, property age, location, property quality and other factors. J.P. Morgan applied a range of capitalization rates, which differed by asset, of 5.00%, at the low end, to 7.50%, at the high end, to the 2013 estimated cash net operating income for each property in MAA’s portfolio to arrive at an aggregate value for the property portfolio at March 31, 2013. The capitalization rate range represented estimated private market capitalization rates by property type, market size and quality based on research analyst estimates. To this aggregate value amount, J.P. Morgan added the value of other tangible real estate and non-real estate assets, including land and capital improvement projects. From gross asset value, J.P. Morgan deducted debt balances, other tangible liabilities, a debt mark-to-market adjustment and a swap mark-to-market adjustment.

J.P. Morgan prepared a per share net asset value analysis for Colonial using 2013 estimated cash net operating income and asset and liability balances as of March 31, 2013. Capitalization rate ranges varied by property based on the type of property, property age, location, property quality and other factors. J.P. Morgan applied a range of capitalization rates, which differed by asset, of 4.25%, at the low end, to 7.00%, at the high end, to the 2013 estimated cash net operating income for each multifamily property in Colonial’s portfolio to arrive at an aggregate value for the property portfolio at March 31, 2013. Similarly, J.P. Morgan applied a range of capitalization rates, which differed by asset, of 6.50%, at the low end, to 9.00%, at the high end, to the 2013 estimated cash net operating income for each commercial property in Colonial’s portfolio to arrive at an aggregate value for the property portfolio at March 31, 2013. The capitalization rate range represented the estimated private market capitalization rates by property type, market size and quality based on research analyst estimates. To this aggregate value amount, J.P. Morgan added the value of other tangible real estate and non-real estate assets, including land and capital improvement projects. From gross asset value, J.P. Morgan deducted debt balances, other tangible liabilities, a debt mark-to-market adjustment and a swap mark-to-market adjustment. Synergies were not taken into account in the net asset value analysis for either MAA or Colonial. The analysis indicated the following equity values per share of MAA common stock and Colonial common share.


	Equity value per MAA share		Equity value per Colonial share
Net asset valuation analysis	$	64.70 – $74.30	$	22.80 – $27.10

Discounted Cash Flow Analysis. J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining the fully diluted equity value per share for each of MAA’s common stock and Colonial’s common shares. J.P. Morgan calculated the unlevered free cash flows that MAA and Colonial are expected to generate during fiscal years 2013 through 2022 as provided by MAA’s management. J.P. Morgan also calculated a range of terminal asset values of each of MAA and Colonial at the end of the 10-year period ending December 31, 2022 by applying a perpetual growth rate ranging from 2.25% to 2.75% of the unlevered free cash flow of each company during the final year of the 10-year period. The unlevered free cash flows and the range of terminal

100

asset values were then discounted to present values using a range of discount rates from 7.5% to 8.0%, which were chosen by J.P. Morgan based upon an analysis of the weighted average cost of capital of selected REITs, which were chosen because they are publicly traded REITs with operations that, for purposes of the analysis of J.P. Morgan, may be considered similar to those of MAA and Colonial, including primarily the ownership of multifamily real estate. The present value of the unlevered free cash flows and the range of terminal asset values were then adjusted for each company’s cash and debt balances as of March 31, 2013. The Colonial value was further adjusted based on the value of assets under letters of intent or recently completed property divestitures of $217 million and the value of land not developed by 2022 of $51 million. The analysis indicated the following equity values per share of MAA common stock and Colonial common share.


	Equity value per MAA share		Equity value per Colonial share
Discounted cash flow analysis	$	60.90 – $83.00	$	22.80 – $30.00

Relative Value Analysis. Based upon a comparison of the range of implied equity values for each of MAA and Colonial calculated pursuant to the trading multiples analysis, net asset value analysis and discounted cash flow analysis, J.P. Morgan calculated a range of implied exchange ratios for the transaction. This analysis indicated the following implied exchange ratios:


	Range of implied exchange ratios
Public trading multiples
Price / CY14 FFO per share		0.262x – 0.385x
Price / CY14 AFFO per share		0.259x – 0.403x
Net asset value analysis		0.307x – 0.419x
Discounted cash flow analysis		0.275x – 0.493x

J.P. Morgan then compared the range of implied exchange ratios above to the natural exchange ratio of 0.325x (calculated as Colonial’s market price divided by MAA’s market price as of May 30, 2013) and the exchange ratio of 0.360x.

Value Creation Analysis—Intrinsic Value Approach. J.P. Morgan prepared a value creation analysis that compared the implied equity value of MAA’s common stock per share based on the discounted cash flow analysis to the pro forma Combined Corporation equity value per share. The pro forma Combined Corporation equity value was equal to: (1) (a) the mid-point equity value of MAA using discounted cash flow analysis at a discount rate of 7.75%, plus (b) the mid-point equity value of Colonial using discounted cash flow analysis at a discount rate of 7.75%, plus (c) the net present value of expected synergies calculated by discounting the expected cash flows from MAA management’s estimated synergies at a discount rate of 7.75%, less (d) an estimated $60 million of costs to achieve such synergies and transaction-related expenses; divided by (2) pro forma diluted shares outstanding of the Combined Corporation common stock. There can be no assurance that the synergies, estimated cost to achieve such synergies or estimated transaction-related expenses will not be substantially greater or less than MAA management’s estimates. Similarly, there can be no assurance that the discount rate will not be substantially greater or less than J.P. Morgan’s estimates. This analysis, at the exchange ratio of 0.360x provided for in the parent merger, resulted in an implied value creation to the holders of MAA common stock of 8.2%.

Other Analyses. J.P. Morgan also noted the historical exchange ratio and accretion/dilution analyses described below for reference purposes only and not as a component of its fairness analysis. These analyses did not form a basis for, and were not relied on in forming, J.P. Morgan’s opinion.

J.P. Morgan calculated (1) the implied historical exchange ratios during the one-year period ended May 30, 2013 by dividing the daily closing price per Colonial common share by that of a share of MAA common stock for each trading day during that period and (2) the average of those daily implied historical exchange ratios for

101

the ten-days, one-month, three-months, six-months, and one-year periods ending May 30, 2013. J.P. Morgan also noted the low and high exchange ratios for each period referenced in clause (2) above and the resulting premiums of the proposed exchange ratio to the average exchange ratios for each such period. The analysis resulted in the following implied exchange ratios for the periods indicated, as compared to the exchange ratio of 0.360x provided for in the parent merger:

10-day

1-month

3-months

6-months

1-year

Average

0.329x

0.328x

0.327x

J.P. Morgan reviewed the potential pro forma financial effects of the parent merger, taking into account, among other things, MAA management’s estimated synergies, on the Combined Corporation’s estimated FFO and AFFO during calendar years 2014 and 2015. Based on the exchange ratio in the parent merger, this analysis indicated that, on a pro forma basis, the parent merger could be accretive relative to the Combined Corporation’s estimated FFO during calendar years 2014 and 2015 and dilutive relative to the Combined Corporation’s estimated AFFO during calendar years 2014 and 2015.

The following presents the results of this analysis:


	$ per share			%
FFO per share accretion/dilution
2014E	$	0.12			2.3	%
2015E	$	0.09			1.7	%
AFFO per share accretion/dilution
2014E	($	0.08	)		(1.7	%)
2015E	($	0.03	)		(0.7	%)

The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by J.P. Morgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors considered by it and did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the totality of the factors and analyses performed in determining its opinion. Analyses based upon forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by J.P. Morgan are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be bought or sold. None of the selected companies reviewed as described in the above summary is identical to MAA or Colonial. However, the companies selected were chosen because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of MAA or Colonial. The analysis necessarily involves complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to MAA or Colonial.

As a part of its investment banking business, J.P. Morgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements, and valuations for estate, corporate and other purposes. J.P. Morgan was selected to advise MAA with respect to the parent merger on the basis of such experience and its familiarity with MAA.

102

For services rendered in connection with the parent merger, MAA has agreed to pay J.P. Morgan a fee of $12 million, $2 million of which was payable upon delivery by J.P. Morgan of its opinion and the remainder of which will be payable contingent upon closing of the parent merger. In addition to the transaction fee, MAA may, at its sole discretion, pay J.P. Morgan an additional discretionary fee at closing of $2 million, based on MAA’s assessment of J.P. Morgan’s performance of its services rendered in connection with the parent merger. In addition, MAA has agreed to reimburse J.P. Morgan for its reasonable expenses incurred in connection with its services, including the reasonable fees and disbursements of counsel, and will indemnify J.P. Morgan against certain liabilities, including liabilities arising under the Federal securities laws.

During the two years preceding the date of its oral opinion, J.P. Morgan and its affiliates have had commercial or investment banking relationships with MAA, for which J.P. Morgan and its affiliates received customary compensation or other financial benefits. Such services during such period have included acting as co-lead arranger on MAA’s term loan credit facility in March of 2012 and acting as joint bookrunner on MAA’s equity offering in March of 2013. In addition, J.P. Morgan’s commercial banking affiliate is an agent bank and a lender under certain outstanding credit facilities of MAA. In June 2013, following delivery of its oral opinion, J.P. Morgan’s commercial banking affiliate also agreed to act as administrative agent, lead arranger and lender under MAA’s new term loan credit facility. During such period, neither J.P. Morgan nor its affiliates have had any material financial advisory or other material commercial or investment banking relationships with Colonial. In the ordinary course of their businesses, J.P. Morgan and its affiliates may actively trade the debt and equity securities of MAA or Colonial for their own accounts or for the accounts of customers and, accordingly, they may at any time hold long or short positions in such securities.

Opinion of Colonial’s Financial Advisor

Colonial has retained Merrill Lynch, Pierce, Fenner & Smith Incorporated, which we refer to as BofA Merrill Lynch, to act as Colonial’s financial advisor in connection with the mergers. BofA Merrill Lynch is an internationally recognized investment banking firm, which is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. Colonial selected BofA Merrill Lynch to act as Colonial’s financial advisor on the basis of BofA Merrill Lynch’s experience in similar transactions, its reputation in the investment community and its familiarity with Colonial and its business.

At a June 2, 2013 meeting of the Colonial Board held to evaluate the parent merger, BofA Merrill Lynch rendered to the Colonial Board an oral opinion, confirmed by delivery of a written opinion dated June 2, 2013, to the effect that, as of that date and based on and subject to various assumptions and limitations described in the opinion, the exchange ratio provided for in the parent merger was fair, from a financial point of view, to the holders of Colonial common shares.

The full text of BofA Merrill Lynch’s written opinion, dated June 2, 2013, is attached as Annex G to this joint proxy statement/prospectus and is incorporated in this document by reference. The written opinion sets forth, among other things, the assumptions made, procedures followed, factors considered and limitations on the review undertaken by BofA Merrill Lynch in rendering its opinion. The following summary of BofA Merrill Lynch’s opinion is qualified in its entirety by reference to the full text of the opinion. BofA Merrill Lynch delivered its opinion to the Colonial Board for the benefit and use of the Colonial Board (in its capacity as such) in connection with and for purposes of its evaluation of the exchange ratio provided for in the parent merger from a financial point of view. BofA Merrill Lynch’s opinion did not address any other aspect of the mergers and no opinion or view was expressed as to the relative merits of the mergers in comparison to other strategies or transactions that might be available to Colonial or in which Colonial might engage or as to the underlying business decision of Colonial to proceed with or effect the mergers. BofA Merrill Lynch also expressed no opinion or recommendation as to how any shareholder should vote or act in connection with the mergers or any other matter.

103

In connection with its opinion, BofA Merrill Lynch, among other things:

•

reviewed certain publicly available business and financial information relating to Colonial and MAA;

•

reviewed certain internal financial and operating information with respect to the business, operations and prospects of Colonial furnished to or discussed with BofA Merrill Lynch by Colonial’s management, including certain financial forecasts relating to Colonial prepared by Colonial management, referred to as the Colonial forecasts;

•

reviewed certain internal financial and operating information with respect to the business, operations and prospects of MAA furnished to or discussed with BofA Merrill Lynch by MAA’s management, including certain financial forecasts relating to MAA prepared by such management, referred to as the MAA forecasts;

•

reviewed certain estimates as to the amount and timing of cost savings, referred to as the cost savings, anticipated by the managements of Colonial and MAA to result from the mergers;

•

discussed with the management of Colonial and MAA the past and current business, operations, financial condition and prospects of Colonial and MAA;

•

reviewed the potential pro forma financial impact of the transaction to be effected by the mergers on the future financial performance of MAA after taking into account potential cost savings, including the potential effect on MAA’s estimated funds from operations and adjusted funds from operations;

•

reviewed the trading histories for Colonial common shares and shares of MAA common stock and a comparison of such trading histories with each other and with the trading histories of other companies BofA Merrill Lynch deemed relevant;

•

compared certain financial and stock market information of Colonial and MAA with similar information of other companies BofA Merrill Lynch deemed relevant;

•

compared certain financial terms of the parent merger to financial terms, to the extent publicly available, of other transactions BofA Merrill Lynch deemed relevant;

•

reviewed the relative financial contributions of Colonial and MAA to the future financial performance of the Combined Corporation on a pro forma basis;

•

reviewed a draft dated June 2, 2013 of the merger agreement; and

•

performed such other analyses and studies and considered such other information and factors as BofA Merrill Lynch deemed appropriate.

In arriving at its opinion, BofA Merrill Lynch assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with BofA Merrill Lynch and relied upon assurances of the managements of Colonial and MAA that they were not aware of any facts or circumstances that would make such information or data inaccurate or misleading in any material respect. With respect to the Colonial forecasts, the MAA forecasts and the cost savings, BofA Merrill Lynch was advised by the managements of Colonial and MAA, and BofA Merrill Lynch assumed, with Colonial’s consent, that they were reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of such managements as to the future financial performance of Colonial and MAA and the other matters covered thereby, and further assumed, with Colonial’s consent, that such cost savings would be realized in the amounts and at the times projected. BofA Merrill Lynch relied, at Colonial’s direction, upon the assessments of the managements of Colonial and MAA as to the ability to integrate the businesses and operations of Colonial and MAA.

BofA Merrill Lynch did not make and was not provided with any independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of Colonial, MAA or any other entity, nor did BofA Merrill Lynch make any physical inspection of the properties or assets of Colonial, MAA or any other entity. BofA Merrill

104

Lynch did not evaluate the solvency or fair value of Colonial, MAA or any other entity under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. BofA Merrill Lynch assumed, at Colonial’s direction, that the mergers would be consummated in accordance with their terms, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary governmental, regulatory and other approvals, consents, releases and waivers for the mergers, no delay, limitation, restriction or condition, including any divestiture requirements or amendments or modifications, would be imposed that would have an adverse effect on Colonial, MAA or the mergers (including the contemplated benefits thereof) and that no such adverse effect would result in the event that the mergers were effected through an alternative structure as permitted under the terms of the merger agreement. BofA Merrill Lynch also assumed, at Colonial’s direction, that the final executed merger agreement would not differ in any material respect from the draft merger agreement reviewed by BofA Merrill Lynch. BofA Merrill Lynch further assumed, at Colonial’s direction, that the parent merger would qualify for U.S. federal income tax purposes as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended, and that the partnership merger would qualify as an “asset-over” form of merger under Treasury Regulations Section 1.708-1(c)(3)(i). BofA Merrill Lynch was advised by Colonial and MAA that each of Colonial and MAA had operated in conformity with the requirements for qualification as a REIT for U.S. federal income tax purposes since its formation as a REIT and further assumed, at Colonial’s direction, that the mergers would not adversely affect such status or operations of Colonial or MAA.

BofA Merrill Lynch expressed no view or opinion as to any terms or other aspects or implications of the mergers (other than the exchange ratio provided for in the parent merger to the extent expressly specified in its opinion), including, without limitation, the form or structure of the mergers, any terms, aspects or implications of the partnership merger (including any consideration payable in such partnership merger), any transfer of assets contemplated to be undertaken in connection with the mergers or any other arrangements, agreements or understandings entered into in connection with or related to the mergers or otherwise. BofA Merrill Lynch was not requested to, and it did not, solicit indications of interest or proposals from third parties regarding a possible acquisition of all or any part of Colonial or any alternative transaction; however, at Colonial’s direction, BofA Merrill Lynch held preliminary discussions with selected third parties that had contacted, or had been contacted by, Colonial. BofA Merrill Lynch’s opinion was limited to the fairness, from a financial point of view, of the exchange ratio provided for in the parent merger to the holders of Colonial common stock and no opinion or view was expressed with respect to any consideration received in connection with the mergers by the holders of any class of securities, creditors or other constituencies of any party. In addition, BofA Merrill Lynch expressed no opinion or view with respect to the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation to any officers, directors, trustees or employees of any party to the mergers, or class of such persons, relative to the exchange ratio or otherwise. BofA Merrill Lynch also expressed no view or opinion with respect to, and relied, with Colonial’s consent, upon the assessments of Colonial’s representatives regarding, legal, regulatory, accounting, tax and similar matters relating to Colonial, MAA and the mergers (including the contemplated benefits thereof) as to which BofA Merrill Lynch understood that Colonial obtained such advice as it deemed necessary from qualified professionals. BofA Merrill Lynch further did not express any opinion as to what the value of the shares of MAA common stock actually would be when issued or the prices at which Colonial common shares or MAA common stock would trade at any time, including following announcement or consummation of the mergers.

BofA Merrill Lynch’s opinion was necessarily based on financial, economic, monetary, market and other conditions and circumstances as in effect on, and the information made available to BofA Merrill Lynch as of, the date of its opinion. The credit, financial and stock markets have been experiencing unusual volatility and BofA Merrill Lynch expressed no opinion or view as to any potential effects of such volatility on Colonial, MAA or the mergers. Although subsequent developments may affect BofA Merrill Lynch’s opinion, BofA Merrill Lynch does not have any obligation to update, revise or reaffirm its opinion. The issuance of BofA Merrill Lynch’s opinion was approved by BofA Merrill Lynch’s Americas Fairness Opinion Review Committee. Except as described in this summary, Colonial imposed no other instructions or limitations on the investigations made or procedures followed by BofA Merrill Lynch in rendering its opinion.

The following is a brief summary of the material financial analyses provided by BofA Merrill Lynch to the Colonial Board in connection with its opinion, dated June 2, 2013. The financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses performed by BofA Merrill Lynch, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses performed by BofA Merrill Lynch. Considering the data set forth in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the financial analyses performed by BofA Merrill Lynch. For purposes of the financial analyses summarized below, the term “implied merger consideration value” refers to $24.47 per share calculated as the implied value of the merger consideration based on the 0.360 fixed exchange ratio and MAA’s closing stock price of $67.97 per share on May 31, 2013. Implied equity value reference ranges derived for Colonial from the analyses described below generally were rounded to the nearest $0.25. In calculating implied exchange ratio reference ranges as reflected in such analyses, BofA Merrill Lynch (i) compared the low-end of the approximate implied per share equity value reference ranges for Colonial to the high-end of the approximate implied per share equity value reference ranges for MAA in order to derive the low-end of the implied exchange ratio reference ranges and (ii) compared the high-end of the approximate implied per share equity reference ranges for Colonial to the low-end of the approximate implied per share equity reference ranges for MAA in order to derive the high-end of the implied exchange ratio reference ranges.

Selected Public Companies Analysis. BofA Merrill Lynch reviewed publicly available financial and stock market information of Colonial, MAA and the following six REITs, which, in its professional judgment, BofA Merrill Lynch generally considered relevant for purposes of its analysis as U.S. publicly traded multifamily REITs, referred to as the selected companies:

•

UDR, Inc.

•

Camden Property Trust

•

Apartment Investment and Management Company

•

Home Properties, Inc.

•

Post Properties, Inc.

•

Associated Estates Realty Corporation

BofA Merrill Lynch reviewed equity values, based on closing stock prices on May 31, 2013, as a multiple of calendar year 2013 estimated funds from operations, referred to as FFO per share. BofA Merrill Lynch also reviewed enterprise values, calculated as equity values based on closing stock prices on May 31, 2013 plus debt, preferred stock and minority interests, less cash and cash equivalents, as a multiple of calendar year 2013 estimated earnings before interest, taxes, depreciation and amortization, referred to as EBITDA. The observed low, median, mean and high calendar year 2013 estimated FFO per share multiples for the selected REITs excluding Colonial, but including MAA which was viewed as a selected REIT for Colonial, were 12.5x, 14.9x, 15.2x and 17.5x, respectively, and the observed low, median, mean and high calendar year 2013 estimated EBITDA multiples were 15.8x, 16.8x, 18.0x and 22.4x, respectively. The observed low, median, mean and high calendar year 2013 estimated FFO per share multiples for the selected REITs excluding MAA, but including Colonial which was viewed as a selected REIT for MAA, were 12.5x, 16.3x, 15.6x and 17.5x, respectively, and the observed low, median, mean and high calendar year 2013 estimated EBITDA multiples were 15.8x, 17.8x, 18.2x and 22.4x, respectively. BofA Merrill Lynch then applied selected ranges derived from the selected REITs of calendar year 2013 estimated FFO per share multiples and calendar year 2013 estimated EBITDA multiples of 15.5x to 17.5x and 17.0x to 18.0x, respectively, to corresponding data of Colonial (adjusted to reflect the sale of Colonial’s Three Ravinia Class A office asset) and applied selected ranges of calendar year 2013 estimated FFO per share multiples and calendar year 2013 estimated EBITDA multiples of 13.5x to 15.5x and 16.0x to 17.0x, respectively, to corresponding data of MAA. Financial data of the selected REITs were based on publicly available research analysts’ estimates, public filings and other publicly available information. Financial data of Colonial and MAA were based on internal forecasts and estimates of the respective managements of Colonial

106

and MAA. This analysis indicated approximate implied per share equity value reference ranges based on calendar year 2013 estimated FFO per share and calendar year 2013 estimated EBITDA for Colonial of $20.75 to $23.50 and $22.50 to $24.75, respectively, and for MAA of $65.75 to $75.50 and $66.25 to $72.75, respectively.

Based upon the approximate implied per share equity value reference ranges for Colonial and MAA described above, BofA Merrill Lynch calculated the following approximate implied exchange ratio reference ranges, as compared to the exchange ratio provided for in the parent merger:


Implied Exchange Ratio Reference Ranges Based on:		Exchange Ratio
2013E FFO	2013E EBITDA	0.360x
0.275x – 0.357x	0.309x – 0.374x

No company used in this analysis is identical or directly comparable to Colonial or MAA. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather, this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the public trading or other values of the companies to which Colonial and MAA were compared.

Selected Precedent Transactions Analysis. BofA Merrill Lynch reviewed publicly available financial information relating to the following five selected transactions which, in its professional judgment, BofA Merrill Lynch generally considered relevant for purposes of its analysis as transactions involving target companies that were U.S. publicly traded multifamily REITs, referred to as the selected transactions:


Announcement Date	Acquiror	Target
5/28/2007	• Tishman Speyer Real Estate Venture VII, L.P. / Lehman Brothers Holdings Inc.	• Archstone-Smith Trust

2/17/2006	• Magazine Acquisition GP LLC (Morgan Stanley Real Estate / Onex Real Estate)	• The Town and Country Trust

6/7/2005	• ING Clarion Partners, LLC	• Gables Residential Trust

10/22/2004	• Colonial	• Cornerstone Realty Income Trust, Inc.

10/4/2004	• Camden Property Trust	• Summit Properties Inc.

BofA Merrill Lynch reviewed transaction values, based on the consideration payable in the selected transactions, as a multiple of the target company’s one-year forward FFO per share. The observed low, median, mean and high one-year forward FFO per share multiples for the selected transactions were 12.9x, 20.1x, 19.3x and 24.6x, respectively. BofA Merrill Lynch then applied a selected range of one-year forward FFO per share multiples derived from the selected transactions of 17.5x to 21.0x to Colonial’s calendar year 2013 estimated FFO per share. Financial data of the selected transactions were based on publicly available research analysts’ reports and financial data of Colonial were based on internal forecasts and estimates of Colonial’s management. This analysis indicated the following approximate implied per share equity value reference ranges for Colonial, as compared to the implied merger consideration value:

Implied Per Share Equity Value

Reference Range for Colonial

Implied Merger
Consideration Value

$23.50 – $28.00

24.47

No company, business or transaction used in this analysis is identical or directly comparable to Colonial or the parent merger. Accordingly, an evaluation of the results of this analysis is not entirely mathematical. Rather,

107

this analysis involves complex considerations and judgments concerning differences in financial and operating characteristics and other factors that could affect the acquisition or other values of the companies, business segments or transactions to which Colonial and the parent merger were compared.

Net Asset Value Analysis. BofA Merrill Lynch performed separate net asset value analyses of Colonial and MAA by calculating the estimated values by asset of Colonial’s and MAA’s respective operating real estate taking into account the estimated value of active developments, vacant land and other tangible assets less the estimated value of outstanding indebtedness and other tangible liabilities. The estimated fair market value of such operating real estate was calculated by applying to Colonial’s and MAA’s respective calendar year 2013 estimated net operating income from operating real estate selected capitalization rates ranging from 5.85% to 6.25% for Colonial’s operating real estate and 5.95% to 6.35% for MAA’s operating real estate. Financial data of Colonial and MAA were based on internal forecasts and estimates of the respective managements of Colonial and MAA. This analysis indicated approximate implied per share net asset value reference ranges for Colonial of $22.25 to $25.00 and for MAA of $63.00 to $69.75.

Based upon the approximate implied per share net asset value reference ranges for Colonial and MAA described above, BofA Merrill Lynch calculated the following approximate implied exchange ratio reference range, as compared to the exchange ratio provided for in the parent merger:

Implied Exchange Ratio

Reference Range

Exchange Ratio

0.319x – 0.397x

0.360x

Discounted Cash Flow Analysis. BofA Merrill Lynch performed separate discounted cash flow analyses of Colonial and MAA by calculating the estimated present value of the standalone unlevered, after-tax free cash flows that Colonial and MAA were each forecasted to generate during the nine months ending December 31, 2013 through the full calendar year ending December 31, 2017 based on internal forecasts and estimates of the respective managements of Colonial and MAA. BofA Merrill Lynch calculated terminal values for Colonial and MAA by applying to the respective calendar year 2018 estimated EBITDA of Colonial and MAA a selected range of terminal value EBITDA multiples for Colonial of 16.0x to 17.0x and for MAA of 15.5x to 16.5x. The unlevered, after-tax free cash flows and terminal values were then discounted to present value (as of March 31, 2013) using discount rates ranging from 7.0% to 8.0% for Colonial and 6.5% to 7.5% for MAA. This analysis indicated approximate implied per share equity value reference ranges for Colonial of $23.50 to $27.25 and for MAA of $64.50 to $76.00.

Based upon the approximate implied per share equity value reference ranges for Colonial and MAA described above, BofA Merrill Lynch calculated the following approximate implied exchange ratio reference range, as compared to the exchange ratio provided for in the parent merger:

Implied Exchange Ratio

Relative Contribution Analysis. BofA Merrill Lynch reviewed the relative financial contributions of Colonial and MAA to the pro forma Combined Corporation based on Colonial’s and MAA’s calendar years 2013 and 2014 estimated EBITDA, FFO and adjusted FFO, referred to as AFFO, utilizing internal forecasts and estimates of the respective managements of Colonial and MAA. BofA Merrill Lynch calculated overall aggregate equity ownership percentages of Colonial and MAA in the pro forma Combined Corporation based on these relative contributions and the respective debt, cash and non-controlling interests of Colonial and MAA, as applicable, which indicated an approximate implied overall contribution percentage reference range for Colonial of 35.5% to 40.9% as compared to the aggregate pro forma equity ownership percentage of Colonial’s shareholders in the Combined Corporation, based on the exchange ratio, of 43.8% immediately upon

108

consummation of the mergers. Based on Colonial’s and MAA’s relative contributions to the pro forma Combined Corporation of the financial metrics described above, BofA Merrill Lynch calculated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the parent merger:

Implied Exchange Ratio

Other Factors. BofA Merrill Lynch observed certain additional factors that were not considered part of BofA Merrill Lynch’s financial analyses with respect to its opinion but were referenced for informational purposes, including, among other things, the following:

•

historical trading performance of Colonial common shares and shares of MAA common stock during the 52-week period ended May 31, 2013, which reflected low to high trading prices for Colonial common shares and the shares of MAA common stock during such period of approximately $19.75 to $25.00 and $60.50 to $75.00 per share, respectively;

•

publicly available Wall Street research analysts’ stock price targets for Colonial and MAA, which indicated ranges of target stock prices for Colonial and MAA of $20.00 to $26.00 per share and $70.00 to $76.00 per share, respectively; and

•

potential pro forma effects of the mergers on the Combined Corporation’s calendar years 2014 and 2015 estimated FFO per share, FFO per share excluding merger accounting adjustments, and AFFO per share based on internal forecasts and estimates of the respective managements of Colonial and MAA and after taking into account potential cost savings anticipated by such managements to result from the mergers, which indicated that the mergers could be (i) in the case of FFO per share, dilutive in calendar year 2014 by approximately (1.9)% and accretive in calendar year 2015 by approximately 0.3%, (ii) in the case of FFO per share excluding merger accounting adjustments, dilutive in calendar years 2014 and 2015 by approximately (6.5)% and (3.3)%, respectively, and (iii) in the case of AFFO per share, dilutive in calendar years 2014 and 2015 by approximately (3.8)% and (0.2)%, respectively. The actual results achieved by the Combined Corporation may vary from forecasted results and the variations may be material.

Miscellaneous

As noted above, the discussion set forth above is a summary of the material financial analyses provided by BofA Merrill Lynch to the Colonial Board in connection with its opinion and is not a comprehensive description of all analyses undertaken or factors considered by BofA Merrill Lynch in connection with its opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to partial analysis or summary description. BofA Merrill Lynch believes that the analyses summarized above must be considered as a whole. BofA Merrill Lynch further believes that selecting portions of its analyses or factors considered or focusing on information presented in tabular format, without considering all analyses or factors or the narrative description of such analyses or factors, could create a misleading or incomplete view of the processes underlying BofA Merrill Lynch’s analyses and opinion. The fact that any specific analysis has been referred to in the summary above is not meant to indicate that such analysis was given greater weight than any other analysis referred to in the summary.

In performing its analyses, BofA Merrill Lynch considered industry performance, general business and economic conditions and other matters, many of which are beyond the control of Colonial and MAA. The estimates of the future performance of Colonial and MAA in or underlying BofA Merrill Lynch’s analyses are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than those estimates or those suggested by BofA Merrill Lynch’s analyses. These analyses were

109

prepared solely as part of BofA Merrill Lynch’s analysis of the fairness, from a financial point of view, of the exchange ratio provided for in the parent merger and were provided to the Colonial Board in connection with the delivery of BofA Merrill Lynch’s opinion. The analyses do not purport to be appraisals or to reflect the prices at which a company might actually be sold or acquired or the prices at which any securities have traded or may trade at any time in the future. Accordingly, the estimates used in, and the ranges of valuations resulting from, any particular analysis described above are inherently subject to substantial uncertainty and should not be taken to be BofA Merrill Lynch’s view of the actual value of Colonial or MAA.

The type and amount of consideration payable in the mergers was determined through negotiations between Colonial and MAA, rather than by any financial advisor, and was approved by the Colonial Board. The decision to enter into the merger agreement was solely that of the Colonial Board. As described above, BofA Merrill Lynch’s opinion and analyses were only one of many factors considered by the Colonial Board and should not be viewed as determinative of the views of the Colonial Board, management or any other party with respect to the consideration payable in the parent merger or otherwise.

In connection with BofA Merrill Lynch’s services as Colonial’s financial advisor, Colonial has agreed to pay BofA Merrill Lynch an aggregate fee of $11.5 million, $1.0 million of which was payable upon delivery of its opinion and $10.5 million of which is contingent upon consummation of the mergers. Colonial also has agreed to reimburse BofA Merrill Lynch for its expenses incurred in connection with BofA Merrill Lynch’s engagement and to indemnify BofA Merrill Lynch, any controlling person of BofA Merrill Lynch and each of their respective directors, officers, employees, agents and affiliates against specified liabilities, including liabilities under the federal securities laws, arising from BofA Merrill Lynch’s engagement.

BofA Merrill Lynch and its affiliates comprise a full service securities firm and commercial bank engaged in securities, commodities and derivatives trading, foreign exchange and other brokerage activities and principal investing as well as providing investment, corporate and private banking, asset and investment management, financing and financial advisory services and other commercial services and products to a wide range of companies, governments and individuals. In the ordinary course of business, BofA Merrill Lynch and its affiliates may invest on a principal basis or on behalf of customers or manage funds that invest, make or hold long or short positions, finance positions or trade or otherwise effect transactions in equity, debt or other securities or financial instruments (including derivatives, bank loans or other obligations) of Colonial, MAA and certain of their respective affiliates.

BofA Merrill Lynch and its affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services to Colonial and have received or in the future may receive compensation for the rendering of these services, including (i) having acted or acting as joint lead arranger and bookrunner for, and/or as a lender under, certain letters of credit, and credit and leasing facilities of Colonial, including Colonial’s $500 million unsecured revolving credit facility due 2016, and (ii) having acted or acting as a joint sales agent in connection with certain “at-the-market” common equity offerings of Colonial. From January 1, 2011 through May 31, 2013, BofA Merrill Lynch and its affiliates derived aggregate revenues of approximately $3.1 million from Colonial for corporate, commercial and investment banking services unrelated to the mergers.

BofA Merrill Lynch and its affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services to MAA and have received or in the future may receive compensation for the rendering of these services, including (i) having acted or acting as a lender under certain leasing facilities of MAA, and (ii) having acted or acting as a joint sales agent in connection with certain “at-the-market” common equity offerings of MAA. From January 1, 2011 through May 31, 2013, BofA Merrill Lynch and its affiliates derived aggregate revenues of approximately $1.6 million from MAA for corporate, commercial and investment banking services unrelated to the mergers.

Certain MAA Unaudited Prospective Financial Information

MAA does not as a matter of course make public long-term projections as to future revenues, earnings or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. However, MAA is including certain unaudited prospective financial information that was made available to the MAA Board and the Colonial Board in connection with the evaluation of the mergers. This information also was provided to MAA’s and Colonial’s respective financial advisors. The inclusion of this information should not be regarded as an indication that any of MAA, Colonial, their respective affiliates, advisors or other representatives or any other recipient of this information considered, or now considers, it to be necessarily predictive of actual future results.

The unaudited prospective financial information was, in general, prepared solely for internal use and is subjective in many respects. As a result, the prospective results may not be realized and the actual results may be significantly higher or lower than estimated. Since the unaudited prospective financial information covers multiple years, that information by its nature becomes less predictive with each successive year. You are encouraged to review the risks and uncertainties described under the headings “Risk Factors—Risk Factors Relating to the Mergers” beginning on page 32 and “Cautionary Statement Concerning Forward-Looking Statements” beginning on page 43 and the risks described in the periodic reports filed by MAA with the SEC, which reports can be found as described under the heading “Where You Can Find More Information” beginning on page 201. The unaudited prospective financial information was not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with GAAP, published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. In addition, the unaudited prospective financial information requires significant estimates and assumptions that make it inherently less comparable to the similarly titled GAAP measures in MAA’s historical GAAP financial statements. Neither MAA’s independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the unaudited prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on the information or its achievability. Neither MAA independent auditors, nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information.

The report of MAA’s independent registered public accounting firm of MAA contained in the Annual Report on Form 10-K for the year ended December 31, 2012, which is incorporated by reference into this joint proxy statement/prospectus, relates to MAA’s historical financial information. It does not extend to the unaudited prospective financial information and should not be read to do so. Furthermore, the unaudited prospective financial information does not take into account any circumstances or events occurring after the date it was prepared.

The following table presents selected unaudited prospective financial data for the fiscal years ending 2013 through 2017 for MAA on a standalone basis.


	2013		2014		2015		2016		2017
	($ in millions, except per share values)
Net Operating Income (NOI)	$	324.5	$	345.8	$	374.8	$	406.5	$	438.3
Funds from Operations (FFO) per share	$	4.87	$	5.14	$	5.48	$	5.86	$	6.19
Adjusted Funds from Operations (AFFO) per share	$	4.22	$	4.46	$	4.78	$	5.15	$	5.45

For purposes of the unaudited prospective financial information presented herein, NOI is a non-GAAP financial performance measure that represents total property revenues less total property operating expenses, excluding depreciation and amortization, for all properties held during the period regardless of their status as held for sale. FFO is a non-GAAP financial performance measure defined by the National Association of Real Estate Investment Trusts, referred to herein as NAREIT, and represents net income (computed in accordance with GAAP) excluding extraordinary items, net income attributable to noncontrolling interest, asset impairment, gains or losses on disposition of real estate assets, plus depreciation and amortization of real estate, and adjustments for

111

joint ventures to reflect FFO on the same basis. AFFO is a non-GAAP financial performance measure that represents FFO less recurring capital expenditures, any amount charged to retire preferred stock in excess of carrying values and asset impairment.

Colonial and MAA calculate certain non-GAAP financial metrics including NOI, FFO and AFFO using different methodologies. Consequently, the financial metrics presented in each company’s prospective financial information disclosures and in the sections of this joint proxy statement/prospectus with respect to the opinions of the financial advisors to MAA and Colonial may not be directly comparable to one another.

In preparing the foregoing unaudited projected financial information, MAA made a number of assumptions regarding, among other things, interest rates, corporate financing activities, annual dividend levels, occupancy and customer retention levels, changes in rent, the amount, timing and cost of existing and planned development properties, lease-up rates of existing and planned developments, the amount and timing of asset sales and asset acquisitions, including the return on those acquisitions, the amount of income taxes paid, and the amount of general and administrative costs.

The assumptions made in preparing the above unaudited prospective financial information may not necessarily reflect actual future conditions. The estimates and assumptions underlying the unaudited prospective financial information involve judgments with respect to, among other things, future economic, competitive, regulatory and financial market conditions and future business decisions which may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among others, risks and uncertainties described under the headings “Risk Factors—Risk Factors Relating to the Mergers” beginning on page 32 and “Cautionary Statement Concerning Forward-Looking Statements” beginning on page 43 and the risks described in the periodic reports filed by MAA with the SEC, which reports can be found as described under the heading “Where You Can Find More Information” beginning on page 201, all of which are difficult to predict and many of which are beyond the control of MAA and/or Colonial and will be beyond the control of the Combined Corporation. The underlying assumptions and projected results may not be realized, and actual results likely will differ, and may differ materially, from those reflected in the unaudited prospective financial information, whether or not the mergers are completed.

In addition, although presented with numerical specificity, the above unaudited prospective financial information reflects numerous assumptions and estimates as to future events made by MAA management that MAA management believes were reasonably prepared. The above unaudited prospective financial information does not give effect to the mergers. MAA shareholders and Colonial shareholders are urged to review the most recent SEC filings of MAA for a description of the reported and anticipated results of operations and financial condition and capital resources during 2012, including in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in MAA’s Annual Report on Form 10-K for the year ended December 31, 2012, and subsequent quarterly reports on Form 10-Q, which is incorporated by reference into this joint proxy statement/prospectus.

Readers of this joint proxy statement/prospectus are cautioned not to place undue reliance on the unaudited prospective financial information set forth above. No representation is made by MAA, Colonial or any other person to any MAA shareholder or any Colonial shareholder regarding the ultimate performance of MAA compared to the information included in the above unaudited prospective financial information. The inclusion of unaudited prospective financial information in this joint proxy statement/prospectus should not be regarded as an indication that the prospective financial information will be necessarily predictive of actual future events, and such information should not be relied on as such.

MAA DOES NOT INTEND TO UPDATE OR OTHERWISE REVISE THE ABOVE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE WHEN MADE OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE PROSPECTIVE FINANCIAL INFORMATION ARE NO LONGER APPROPRIATE, EXCEPT AS MAY BE REQUIRED BY LAW.

112

Certain Colonial Unaudited Prospective Financial Information

Colonial does not as a matter of course make public projections as to future revenues, earnings or other results. However, the management of Colonial has prepared the unaudited prospective financial information set forth below in connection with an evaluation of the mergers. This information was made available to the Colonial Board and the MAA Board in connection with the evaluation of the mergers and also was provided to Colonial’s and MAA’s respective financial advisors.

The accompanying prospective financial information was not prepared with a view toward public disclosure or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information, but, in the view of Colonial’s management, was prepared on a reasonable basis, reflects the best currently available estimates and judgments, and presents, to the best of management’s knowledge and belief, the expected course of action and the expected future financial performance of Colonial. However, this information is not fact and should not be relied upon as being necessarily indicative of future results, and readers of this joint proxy statement/prospectus are cautioned not to place undue reliance on the prospective financial information. Neither Colonial’s independent auditors, nor any other independent accountants, have compiled, examined, or performed any procedures with respect to the prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information

The assumptions and estimates underlying the prospective financial information are inherently uncertain and, though considered reasonable by the management of Colonial as of the date of its preparation, are subject to a wide variety of significant business, economic, and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information, including, among others, risks and uncertainties. See “Risk Factors—Risk Factors Relating to the Mergers” beginning on page 32 and “Cautionary Statement Concerning Forward-Looking Statements” beginning on page 43 and the risks described in the periodic reports filed by Colonial with the SEC, which reports can be found as described under the heading “Where You Can Find More Information” beginning on page 201.

Accordingly, there can be no assurance that the prospective results are indicative of the future performance of Colonial or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this joint proxy statement/prospectus should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Colonial does not generally publish its business plans and strategies or make external disclosures of its anticipated financial position or results of operations. Accordingly, Colonial does not intend to update or otherwise revise the prospective financial information to reflect circumstances existing since its preparation or to reflect the occurrence of unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error. Furthermore, Colonial does not intend to update or revise the prospective financial information to reflect changes in general economic or industry conditions.

The following table presents selected unaudited prospective financial data for the fiscal years ending December 31, 2013 through 2017 for Colonial on a standalone basis.


	2013		2014		2015		2016		2017
	($ in millions, except per share values)
Net Operating Income (NOI)	$	217.0	$	222.5	$	243.2	$	255.8	$	264.7
Funds from Operations (FFO) per share	$	1.34	$	1.40	$	1.57	$	1.69	$	1.79
Adjusted Funds from Operations (AFFO) per share	$	1.08	$	1.17	$	1.34	$	1.47	$	1.57

For purposes of the unaudited prospective financial information presented herein, NOI is a non-GAAP financial performance measure that represents total property revenues (including minimum rent and other property-related revenue) less total property operating expenses, (including such items as general and

113

administrative expenses, on-site payroll, repairs and maintenance, real estate taxes, insurance and advertising), and includes revenues/expenses from unconsolidated partnerships and joint ventures. FFO is a non-GAAP financial performance measure defined by NAREIT, and represents net income (loss) before noncontrolling interest (determined in accordance with GAAP), excluding sales of depreciated property and impairment write-downs of depreciable real estate, plus real estate depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures. AFFO is a non-GAAP financial performance measure that represents FFO adjusted for capital expenditures, tenant improvements, leasing commissions, straight line rents and above or below market income.

Colonial and MAA calculate certain non-GAAP financial metrics including NOI, FFO and AFFO using different methodologies. Consequently, the financial metrics presented in each company’s prospective financial information disclosures and in the sections of this joint proxy statement/prospectus with respect to the opinions of the financial advisors to Colonial and MAA may not be directly comparable to one another.

In preparing the foregoing unaudited projected financial information, Colonial made a number of assumptions regarding, among other things, interest rates, corporate financing activities, annual dividend levels, occupancy and customer retention levels, changes in rent, the amount, timing and cost of existing and planned development properties, lease-up rates of existing and planned developments, the amount and timing of asset sales and asset acquisitions, including the return on those acquisitions, the amount of income taxes paid, and the amount of general and administrative costs.

The assumptions made in preparing the above unaudited prospective financial information may not accurately reflect future conditions. The estimates and assumptions underlying the unaudited prospective financial information involve judgments with respect to, among other things, future economic, competitive, regulatory and financial market conditions and future business decisions which may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among others, risks and uncertainties described under the headings “Risk Factors—Risk Factors Relating to the Mergers” beginning on page 32 and “Cautionary Statement Concerning Forward-Looking Statements” beginning on page 43 and the risks described in the periodic reports filed by Colonial with the SEC, which reports can be found as described under the heading “Where You Can Find More Information” beginning on page 201, all of which are difficult to predict and many of which are beyond the control of Colonial and/or MAA and will be beyond the control of the Combined Corporation. The underlying assumptions and projected results may not be realized, and actual results likely will differ, and may differ materially, from those reflected in the unaudited prospective financial information, whether or not the mergers are completed.

In addition, although presented with numerical specificity, the above unaudited prospective financial information reflects numerous assumptions and estimates as to future events made by Colonial management that Colonial management believes were reasonably prepared. The above unaudited prospective financial information does not give effect to the mergers. Colonial shareholders and MAA shareholders are urged to review the most recent SEC filings of Colonial for a description of the reported and anticipated results of operations and financial condition and capital resources during 2012, including in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Colonial’s Annual Report on Form 10-K for the year ended December 31, 2012, and subsequent quarterly reports on Form 10-Q, which is incorporated by reference into this joint proxy statement/prospectus.

Readers of this joint proxy statement/prospectus are cautioned not to place undue reliance on the unaudited prospective financial information set forth above. No representation is made by Colonial, MAA or any other person to any Colonial shareholder or any MAA shareholder regarding the ultimate performance of Colonial compared to the information included in the above unaudited prospective financial information. The inclusion of unaudited prospective financial information in this joint proxy statement/prospectus should not be regarded as an indication that the prospective financial information will be necessarily predictive of actual future events, and such information should not be relied on as such.

114

COLONIAL DOES NOT INTEND TO UPDATE OR OTHERWISE REVISE THE ABOVE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE WHEN MADE OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE PROSPECTIVE FINANCIAL INFORMATION ARE NO LONGER APPROPRIATE, EXCEPT AS MAY BE REQUIRED BY LAW.

Interests of MAA’s Directors and Executive Officers in the Mergers

In considering the recommendation of the MAA Board to approve the merger agreement, the parent merger and the other transactions contemplated by the merger agreement, MAA shareholders should be aware that certain executive officers and directors of MAA have certain interests in the mergers that may be different from, or in addition to, the interests of MAA shareholders generally. These interests may create potential conflicts of interest. The MAA Board was aware of those interests and considered them, among other matters, in reaching its decision to approve the merger agreement and the transactions contemplated thereby.

Following the consummation of the mergers, all seven of the current members of the MAA Board will continue as members of the board of directors of the Combined Corporation. H. Eric Bolton, Jr., MAA’s Chief Executive Officer and Chairman of the Board of Directors, will serve as Chief Executive Officer and Chairman of the Board of Directors of the Combined Corporation. Alan B. Graf, Jr. and Ralph Horn, Co-Lead Independent Directors for MAA, will serve as Co-Lead Independent Directors for the Combined Corporation. In addition, Albert M. Campbell, III, MAA’s Chief Financial Officer, will serve as Chief Financial Officer of the Combined Corporation, and Thomas L. Grimes, Jr., MAA’s Chief Operating Officer, will serve as the Chief Operating Officer of the Combined Corporation.H. Eric Bolton, Jr., MAA’s Chief Executive Officer and Chairman of the Board of Directors, and W. Reid Sanders, a director of MAA, each own limited partnership units in MAA LP. The ownership of these limited partnership units may result in Messrs. Bolton and Sanders having interests in the mergers that are different from, or in addition to, those of MAA shareholders generally. In connection with the mergers, MAA has agreed to amend and restate the limited partnership agreement of MAA LP to contain substantially the same provisions as contained in the existing limited partnership agreement of Colonial LP including, in particular, for the benefit of limited partners in MAA LP after the partnership merger, a provision relating to the consideration of the income tax considerations of limited partners of MAA LP with respect to actions taken by the general partner of MAA LP. Messrs. Bolton and Sanders, as limited partners of MAA LP, will have the benefits of this provision following the partnership merger.

Employment Agreements and Change of Control Agreements with MAA’s Executive Officers

Certain MAA executives, including H. Eric Bolton, Jr., Albert M. Campbell III, and Thomas L. Grimes, Jr., are parties to either employment agreements or change in control and termination agreements with MAA, each of which provides for, among other things, severance payments and benefits upon a qualifying termination of employment without “cause” or for “good reason” upon or after a “change of control” (each, as defined in the applicable agreement), and, pursuant to the terms of the applicable agreements, these MAA executives are entitled to accelerated vesting of restricted stock awards upon such qualifying termination. Additionally, pursuant to the terms of certain awards of restricted stock granted to each MAA executive officer under MAA’s 2004 Stock Plan, vesting will accelerate upon a “change in control” (as defined in the applicable award agreement). The mergers will constitute a “change in control” for purposes of these agreements and MAA’s 2004 Stock Plan.

Waiver Agreements

On June 3, 2013, at the request of the MAA Board, MAA entered into waiver agreements with each of its executive officers, which provide that (i) the mergers will not constitute a “change in control” for purposes of the MAA executive’s employment agreement or change in control and termination agreement, as applicable, and related restricted stock agreement(s), (ii) any termination of the executive’s employment that occurs in connection with or following the mergers will not constitute a “change in control termination” for purposes of the

115

employment agreement or change in control and termination agreement, as applicable, and (iii) the vesting or payment of any restricted stock held by the executive shall not automatically accelerate upon or solely in connection with the mergers. Therefore, as a result of such waivers, none of MAA’s executive officers is a party to an agreement with MAA, or participates in any MAA plan, program or arrangement, that provides for payments or benefits based on or that otherwise relate to the consummation of the mergers.

The MAA Board was aware of the interests described in this section and considered them, among other matters, in approving the merger agreement and making its recommendation that MAA shareholders approve the parent merger and the other transactions contemplated by the merger agreement. See “—Recommendation of the MAA Board and Its Reasons for the Parent Merger” above.

Interests of Colonial’s Trustees and Executive Officers in the Mergers

In considering the recommendation of the Colonial Board to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement, Colonial shareholders should be aware that executive officers and trustees of Colonial have certain interests in the mergers that may be different from, or in addition to, the interests of Colonial shareholders generally. These interests may create potential conflicts of interest. The Colonial Board was aware of those interests and considered them, among other matters, in reaching its decision to approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the transactions contemplated by the merger agreement. These interests include the following:

Severance Arrangements

Prior to the Colonial Board’s approval and adoption of the merger agreement, the executive compensation committee of the Colonial Board, referred to in this joint proxy statement/prospectus as the Colonial Compensation Committee, approved certain severance arrangements described below with respect to Colonial’s executive officers: Thomas M. Lowder, Paul F. Earle, John P. Rigrish, Bradley P. Sandidge, and Jerry Brewer (we refer to each as a Colonial executive officer and collectively as the Colonial executive officers).

In the event that the Colonial executive officer is terminated by Colonial upon the consummation of the mergers and provided that he is continuously employed by Colonial through the closing, the Colonial executives would be entitled to the following severance payments:

•

In addition to payments under his existing Non-Competition Agreement with Colonial LP and Colonial, described further below, Mr. Lowder will receive a severance payment equal to two times the average annual incentive compensation paid to him for the three completed fiscal years immediately preceding the closing of the mergers.

•

Each of Messrs. Earle and Rigrish will receive a severance payment equal to one and one-half times the sum of (1) his annual base salary in effect on the closing date of the mergers, plus (2) the average annual incentive compensation paid to him for the three completed fiscal years immediately preceding the closing of the mergers; and

•

Each of Messrs. Sandidge and Brewer will receive a severance payment equal to one times the sum of (1) his annual base salary in effect on the closing date of the mergers, plus (2) the average annual incentive compensation paid to him for the three completed fiscal years immediately preceding the closing of the mergers.

In the event of such a termination of employment, these severance payments will be payable in a lump-sum payments of cash on or shortly after the closing of the mergers. With respect to Mr. Lowder, such severance payment will be payable in addition to any payments that Mr. Lowder would receive under his existing Non-Competition Agreement with Colonial LP and Colonial, entered into as of May 4, 2007, described further below under “—Change in Control Compensation.”

116

In addition to the severance payments described above, each Colonial executive officer who is terminated by Colonial effective upon the consummation of the mergers will receive a payment with respect to any unused vacation on or shortly after the closing of the mergers, provided that such Colonial executive officer is continuously employed by Colonial through the closing of the mergers.

Pro-Rata Annual Incentive Payments

In connection with the mergers, the Colonial Compensation Committee approved the payment to eligible employees, including the Colonial executive officers, of a pro-rata portion of the employee’s annual incentive under Colonial’s annual incentive plan for 2013 if the employee is terminated by Colonial upon the consummation of the mergers and provided that such employee is continuously employed by Colonial through the closing of the mergers. The pro-rata annual incentive payments will be payable in a lump sum payment of cash on or shortly after the closing of the mergers. The Colonial Compensation Committee will determine Colonial’s achievement as compared to the performance goals specified in the annual incentive plan for 2013 prior to the closing of the mergers and will determine the amount of the pro-rata annual incentive payments based on such achievement.

The performance criteria previously established for the 2013 annual incentive plan are based on a combination of total return for Colonial for the year (the “absolute measure”) and total return for Colonial as compared to an index of comparable REITs over one-, two-, and three- year periods (each, a “relative measure”). For purposes of the 2013 annual incentive plan, “total return” is equal to the share price of Colonial (or the companies in the index of comparable REITs, as the case may be) plus any dividends reinvested in Colonial (or the companies in the index of comparable REITs, as the case may be) calculated based on reinvestment on the ex-dividend pay date.

Colonial’s absolute measure must be positive for the plan year for any payout to occur; however, (1) if the absolute measure is negative but Colonial’s total return is at least at the “median” level of performance when compared to the one-year “total return” relative measure, the Colonial Compensation Committee has discretion to pay up to 20% of the payout calculated based on the relative measures’ results, and (2) if the absolute measure is positive and Colonial’s total return is at least at the “median” level of performance when compared to the one-year “total return” relative measure, the Colonial Compensation Committee has the discretion to increase the award amount up to 20% of the payout calculated based on the relative measures’ results. In addition to this specific discretionary authority, the Colonial Compensation Committee retains discretion to adjust any payment that is otherwise under the terms of the 2013 annual incentive plan. The amounts actually payable to the participants are determined based upon whether Colonial performance meets the “threshold,” “median,” “target” or “maximum” level for the relative measures. For each relative measure, the “threshold” level is the 25^th percentile, the “median” level is the 50^th percentile, the “target” level is the 75^th percentile and the “maximum” level is the 90^th percentile. The relative measures are weighted equally, i.e., 33.33% of any payout is based on the one-year relative measure; 33.33% of any payout is based on the two-year relative measure, and 33.33% of any payout is based on the three-year relative measure.

Under the terms of the 2013 annual incentive plan, the performance payout thresholds were set as follows: (1) for Mr. Lowder, the “threshold” level pays at a maximum of 1% of base salary, the “median” level pays at a maximum of 100% of base salary, the “target” level pays at a maximum of 200% of base salary, and the “maximum” level pays at a maximum of 300% of base salary; (2) for Mr. Earle, the “threshold” level pays at a maximum of 1% of base salary, the “median” level pays at a maximum of 100% of base salary, the “target” level pays at a maximum of 150% of base salary, and the “maximum” level pays at a maximum of 225% of base salary; and (3) for the other Colonial executive officers, the “threshold” level pays at a maximum of 1% of base salary, the “median” level pays at a maximum of 50% of base salary, the “target” level pays at a maximum of 100% of base salary, and the “maximum” level pays at a maximum of 150% of base salary.

117

Treatment of Colonial Options and Restricted Shares

Under the terms of the merger agreement, at the effective time of the parent merger, MAA will assume each outstanding option to acquire Colonial common shares. Each option so assumed by MAA will continue to have, and be subject to, the same terms and conditions, including vesting schedule, as were applicable to the corresponding option immediately prior to the effective time of the parent merger.

In addition, under the merger agreement, immediately prior to the effective time of the parent merger, each then-outstanding restricted Colonial common share will be converted into the right to receive shares of MAA common stock that are subject to the same vesting and forfeiture conditions and other terms and conditions as are applicable to the Colonial restricted share awards immediately prior to the consummation of the parent merger.

As a result of the transactions contemplated under the merger agreement, 1,277,705 options to acquire Colonial common shares held by the Colonial executive officers and trustees that would be exercisable for 459,974 shares of MAA common stock would be assumed by MAA and 386,307 restricted Colonial common shares held by Colonial’s executive officers and trustees would be converted into the right to receive 139,070 shares of MAA common stock pursuant to the parent merger, which based on the closing price of Colonial common shares on [—], 2013, the latest practicable date prior to the filing of this joint proxy statement/prospectus, would have an aggregate value of $[—].

If an eligible employee’s (including a Colonial executive officer’s) employment is terminated by Colonial upon the consummation of the mergers, all restricted shares held by such employee will accelerate in full immediately prior to the closing of the mergers. In addition, all outstanding options held by such eligible employee that are not already fully vested and exercisable will accelerate and become immediately exercisable in full, effective upon the closing of the mergers, and remain exercisable for a 90-day period following the closing of the mergers (or, if earlier, the date the option terminates in accordance with its terms). The above-described acceleration and assumption of unvested options is conditioned upon the consummation of the mergers, the termination of the eligible employee’s employment upon the closing of the mergers, and the continuous employment of the eligible employee with Colonial through the closing of the mergers.

The Colonial Compensation Committee has also provided that in the event that a remaining eligible employee’s (including an executive officer’s) employment is terminated by the Combined Corporation without “cause” (as defined below) or the employee resigns for “good reason,” (as defined below) within one year following the closing of the mergers, the unvested portion of the option and restricted shares held by such eligible employee will become fully vested and each such option may be exercised in full for the one-year period immediately following the effective date of such termination or, if earlier, the date the option terminates in accordance with its terms.

For purposes of the foregoing, “cause” means (1) gross negligence or willful misconduct in connection with the performance of duties; (2) conviction of a criminal offense (other than minor traffic offenses); or (3) material breach of any term of any employment, consulting or other services, confidentiality, intellectual property or non-competition agreements.

For purposes of the foregoing, “good reason” means the occurrence of any of the following events with respect to the employee: (1) a material, adverse alteration in the employee’s title or responsibilities from those in effect immediately prior to the consummation of the mergers; (2) a material reduction in the employee’s base salary and annual target bonus opportunity as of immediately prior to the consummation of the mergers; or (3) the relocation of the employee’s principal place of employment to a location more than 35 miles from the employee’s principal place of employment as of the consummation of the mergers or Colonial’s (or the Combined Corporation’s) requiring the employee to be based anywhere other than such principal place of employment (or permitted relocation thereof) except for required travel on Colonial’s (or the Combined Corporation’s) business to an extent substantially consistent with the employee’s business travel obligations as of

118

immediately prior to the consummation of the mergers. To qualify as a resignation for “good reason” the employee must provide notice to Colonial (or the Combined Corporation) of any of the foregoing occurrences within 90 days of the initial occurrence, Colonial (or the Combined Corporation) will have 30 days to remedy such occurrence, and the employee’s employment must terminate within 30 days after the end of such 30-day cure period.

With respect to each Colonial trustee that will not be joining the MAA Board immediately after the closing of the mergers, all restricted shares held by such trustee will accelerate in full immediately prior to the closing of the mergers and all outstanding options held by such trustee that are not already fully vested and exercisable will accelerate and become immediately exercisable in full, effective upon the closing of the mergers.

The following tables set forth for the Colonial executive officers and trustees the number of (i) Colonial common shares underlying vested Colonial options, (ii) Colonial common shares underlying unvested Colonial options, and (iii) Colonial restricted shares, in each case as held by the executive officers and trustees on July 16, 2013 and assuming continued employment through the date of the closing of the parent merger:

Limited Partner Interests in Colonial LP

Under the merger agreement, in the partnership merger, each limited partner interest in Colonial LP designated as a “Class A Unit” and a “Partnership Unit” under the limited partnership agreement of Colonial LP,

119

which we refer to in this joint proxy statement/prospectus as Colonial LP units, issued and outstanding immediately prior to the effectiveness of the partnership merger (other than limited partner interests owned by Colonial) will be converted into Class A common units in MAA LP, which we refer to in this joint proxy statement/prospectus as new MAA LP units, in an amount equal to (x) 1 multiplied by (y) the 0.36, and each holder of new MAA LP units will be admitted as a limited partner of MAA LP in accordance with the terms of the limited partnership agreement of MAA LP following the effectiveness of the partnership merger.

As of July 16, 2013, the Colonial executive officers and Colonial trustees beneficially owned, in the aggregate, 3,893,154 Colonial LP units. If all of the Colonial LP units beneficially owned by the Colonial executive officers and Colonial trustees as of July 16, 2013 were converted to new MAA LP units in connection with the partnership merger, then the Colonial executive officers and Colonial trustees would receive an aggregate of 1,401,535 new MAA LP units.

As of the effective time of the partnership merger, MAA LP will enter into the Third Amended and Restated Agreement of Limited Partnership of MAA LP, pursuant to which, among other things, the new MAA LP units received by holders of Colonial LP units in the partnership merger will become convertible into an amount of cash equal to the value of a corresponding number of shares of MAA common stock, or, at the option of MAA, the corresponding number of shares of MAA common stock. See “The Merger Agreement—Merger Consideration; Effects of the Parent Merger and the Partnership Merger—Merger Consideration” beginning on page 148.

Directors of MAA after the Parent Merger

Under the merger agreement, within two weeks after the execution and delivery of the merger agreement, Colonial was required to designate five members of the existing Colonial Board to be appointed to the Combined Corporation board of directors following the parent merger. The merger agreement provided that Thomas H. Lowder was to be one of the Colonial designees and that each of the other Colonial designees must be one of the current Colonial Board members listed on a schedule to the merger agreement, which schedule listed the following existing Colonial Board members: James K. Lowder, Claude B. Nielsen, Harold W. Ripps, John W. Spiegel, Edwin M. Crawford and William M. Johnson. On June 10, 2012, the governance committee of the Colonial Board approved Thomas H. Lowder, James K. Lowder, Claude B. Nielsen, Harold W. Ripps and John W. Spiegel to join the Combined Corporation board of directors following the parent merger. Under the terms of the merger agreement, each of the Colonial designees will serve until the 2014 annual meeting of MAA’s shareholders (and until their successors have been elected and qualified) and will be nominated by the MAA board of directors for reelection at the 2014 and 2015 annual meetings of MAA’s shareholders, subject to the satisfaction of such Colonial designees with MAA’s then-current corporate governance guidelines and code of business conduct and ethics. The Colonial designees will be entitled to fees and other compensation and participation in options, share or other benefit plans for which directors of MAA are eligible.

Indemnification and Insurance

For a period of six years after the effective time of the partnership merger, pursuant to the terms of the merger agreement and subject to certain limitations, the Combined Corporation will indemnify and hold harmless, among others, each officer and trustee of Colonial, for actions at or prior to the effective time of the partnership merger, including with respect to the transactions contemplated by the merger agreement, to the fullest extent permitted under applicable law. In addition, pursuant to the terms of the merger agreement and subject to certain limitations, prior to the effective time of the partnership merger, Colonial has agreed to purchase and MAA has agreed to cause to be maintained in full force and effect for a period of six years after the effective time of the partnership merger, a “tail” prepaid insurance policy or policies of at least the same coverage and amounts and containing terms and conditions that are no less favorable to, among others, the officers and trustees of Colonial as Colonial’s existing policies with respect to directors’ and officers’ liability insurance for claims arising from facts or events that occurred on or prior to the effective time of the partnership merger. If such “tail” insurance policy cannot be obtained or can be obtained only by paying an annual premium

120

in excess of 300% of the current annual premium paid by Colonial, MAA will maintain in effect, for a period of at least six years after the effective time of the partnership merger, as much similar insurance as is reasonably practicable for an annual premium equal to 300% of the current annual premium paid by Colonial. These interests are described in detail below at “The Merger Agreement—Covenants and Agreements—Indemnification of Directors and Officers; Insurance.”

The Colonial Board was aware of the interests described in this section and considered them, among other matters, in approving and adopting the merger agreement and the parent merger pursuant to the plan of merger and in making its recommendation that Colonial shareholders approve and adopt the merger agreement, the parent merger pursuant to the plan of merger and the other transactions contemplated by the merger agreement. See “The Parent Merger—Recommendation of the Colonial Board and Its Reasons for the Parent Merger.”

Executive Compensation Payable in Connection with the Mergers

Colonial’s “named executive officers” for purposes of the disclosure in this joint proxy statement/prospectus are Thomas H. Lowder, Paul F. Earle, John P. Rigrish and Bradley P. Sandidge.

Change in Control Compensation

The following table sets forth the information required by Item 402(t) of Regulation S-K promulgated by the SEC, regarding certain compensation that each of Colonial’s named executive officers may receive that is based on, or that otherwise relates to, the mergers. The figures in the table are estimated based on compensation levels as of the date of this document and an assumed effective date of July 16, 2013 (the latest practicable date prior to the filing of this joint proxy statement/prospectus) for both the mergers and the termination of the executive’s employment. The amounts reported below are estimates based on multiple assumptions that may or may not actually occur or be accurate on the relevant date, including an assumption that the employment of each of Colonial’s named executive officers will terminate upon consummation of the mergers and other assumptions described in this document. As required by applicable SEC rules, all amounts below determined using the per share value of Colonial common shares have been calculated based on a per share price of Colonial common shares of $23.55 (the average closing market price of Colonial common shares over the first five business days following the public announcement of the mergers on June 3, 2013). As a result of the foregoing assumptions, the actual amounts, if any, to be received by a named executive officer may materially differ from the amounts set forth below. The merger-related compensation payable to Colonial’s named executive officers is subject to a non-binding advisory vote of Colonial’s shareholders, as described under the section of this joint proxy statement/prospectus captioned “Proposals Submitted to Colonial Shareholders—Advisory Vote on Executive Compensation (Proposal 2 on the Colonial Proxy Card)” beginning on page 64.

Each named executive officer holds unvested options and restricted Colonial common shares that will accelerate in full immediately prior to the closing of the mergers if the executive officer’s employment is terminated by Colonial upon consummation of the mergers. These are double-trigger change-in-control arrangements. The amount shown in the table is based upon the following holdings of options and restricted common shares that would be accelerated upon consummation of the mergers as of July 16, 2013: (i) 230,681 shares underlying options and 173,101 restricted common shares for Mr. Lowder; (ii) 142,073 shares underlying options and 109,525 restricted common shares for Mr. Earle; (iii) 44,267 shares underlying options and 33,439 restricted common shares for Mr. Rigrish; and (iv) 42,399 shares underlying options and 26,833 restricted common shares for Mr. Sandidge. The value for options is equal to the

121

difference between $23.66 per share and the per share exercise price of each such option that would become exercisable, multiplied by the number of common shares receivable upon exercise. The value of restricted common shares is $23.66 per share. These amounts are subject to reduction to the extent the payments would be considered “parachute payments” within the meaning of Section 280G of the Code if such reduction would give the named executive officer a better after-tax result than if he received the full payments.

(2)

This amount represents the sum of: (i) an aggregate payment of $1,100,000 under Mr. Lowder’s Non-Competition Agreement with Colonial LP and Colonial, entered into as of May 4, 2007, payable over the two-year period following Mr. Lowder’s termination of employment and subject to Mr. Lowder’s compliance with the non-competition and non-solicitation provisions set forth in such agreement during such period; (ii) a lump sum payment of $2,030,699, which is equal to two times the average annual incentive compensation paid to him for the three completed fiscal years immediately preceding the closing of the mergers; (iii) a lump sum payment of $42,308, which represents Mr. Lowder’s unused vacation; and (iv) a lump sum payment of $849,452, which represents a pro-rata portion of Mr. Lowder’s annual incentive under Colonial’s annual incentive plan for 2013. The payments in items (ii) through (iv) are double-trigger change-in-control arrangements and are payable only if Mr. Lowder’s employment is terminated by Colonial upon the consummation of the mergers.

(3)

This amount represents the sum of: (i) an aggregate payment of $1,601,444, which is equal to one and one-half times the sum of (A) Mr. Earle’s annual base salary, plus (B) the average annual incentive compensation paid to Mr. Earle for the three completed fiscal years immediately preceding the closing of the mergers; (iii) a lump sum payment of $26,769, which represents Mr. Earle’s unused vacation; and (iv) a lump sum payment of $540,193, which represents a pro-rata portion of Mr. Earle’s annual incentive under Colonial’s annual incentive plan for 2013. These payments are double-trigger change-in-control arrangements and are payable only if Mr. Earle’s employment is terminated by Colonial upon the consummation of the mergers.

(4)

This amount represents the sum of: (i) an aggregate payment of $616,103, which is equal to one and one-half times the sum of (A) Mr. Rigrish’s annual base salary, plus (B) the average annual incentive compensation paid to Mr. Rigrish for the three completed fiscal years immediately preceding the closing of the mergers; (iii) a lump sum payment of $16,538, which represents Mr. Rigrish’s unused vacation; and (iv) a lump sum payment of $166,095, which represents a pro-rata portion of Mr. Rigrish’s annual incentive under Colonial’s annual incentive plan for 2013. These payments are double-trigger change-in-control arrangements and are payable only if Mr. Rigrish’s employment is terminated by Colonial upon the consummation of the mergers.

(5)

This amount represents the sum of: (i) an aggregate payment of $421,958, which is equal to one times the sum of (A) Mr. Sandidge’s annual base salary, plus (B) the average annual incentive compensation paid to Mr. Sandidge for the three completed fiscal years immediately preceding the closing of the mergers; (iii) a lump sum payment of $12,923, which represents Mr. Sandidge’s unused vacation; and (iv) a lump sum payment of $185,409, which represents a pro-rata portion of Mr. Sandidge’s annual incentive under Colonial’s annual incentive plan for 2013. These payments are double-trigger change-in-control arrangements and are payable only if Mr. Sandidge’s employment is terminated by Colonial upon the consummation of the mergers.

Regulatory Approvals Required for the Mergers

Material U.S. Federal Income Tax Consequences of the Parent Merger

The discussion below, as it relates to the material U.S. federal income tax consequences of the parent merger, summarizes such consequences to U.S. holders (as defined below) of Colonial common shares that hold such common shares as a capital asset within the meaning of Section 1221 of the Code.

122

The discussion below, as it relates to the material U.S. federal income tax consequences of holding common stock in the Combined Corporation, summarizes such consequences to certain holders (as specified below) of Combined Corporation common stock that hold such common stock as a capital asset within the meaning of Section 1221 of the Code.

This discussion is based upon the Code, Treasury regulations promulgated under the Code, referred to herein as the Treasury Regulations, judicial decisions and published administrative rulings, all as currently in effect and all of which are subject to change, possibly with retroactive effect. This discussion does not address (i) U.S. federal taxes other than income taxes, (ii) state, local or non-U.S. taxes or (iii) tax reporting requirements, in each case, as applicable to the parent merger. In addition, this discussion does not address U.S. federal income tax considerations applicable to holders of Colonial common shares that are subject to special treatment under U.S. federal income tax law, including, for example:

•

financial institutions;

•

pass-through entities (such as entities treated as partnerships for U.S. federal income tax purposes);

•

insurance companies;

•

broker-dealers;

•

tax-exempt organizations;

•

dealers in securities or currencies;

•

traders in securities that elect to use a mark to market method of accounting;

•

persons that hold Colonial common shares (or, following the effective time of the parent merger, Combined Corporation common stock) as part of a straddle, hedge, constructive sale, conversion transaction, or other integrated transaction for U.S. federal income tax purposes;

•

regulated investment companies;

•

real estate investment trusts;

•

certain U.S. expatriates;

•

non-U.S. holders (as defined below);

•

U.S. holders whose “functional currency” is not the U.S. dollar; and

•

persons who acquired their Colonial common shares (or, following the effective time of the parent merger, Combined Corporation common stock) through the exercise of an employee stock option or otherwise as compensation.

For purposes of this discussion, a “U.S. holder” means a beneficial owner of Colonial common shares (or, following the effective time of the parent merger, of the Combined Corporation common stock) that is:

•

an individual who is a citizen or resident of the United States for U.S. income tax purposes;

•

a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any political subdivision thereof;

•

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust that (A) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (B) has a valid election in place under the Treasury Regulations to be treated as a U.S. person.

For purposes of this discussion, a “non-U.S. holder” means a beneficial owner of Colonial common shares other than a U.S. holder.

123

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Colonial common shares (or, following the parent merger, Combined Corporation common stock), the tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. Any partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes that holds Colonial common shares (or, following the parent merger, the Combined Corporation common stock), and the partners in such partnership (as determined for U.S. federal income tax purposes), should consult their tax advisors.

This discussion of material U.S. federal income tax consequences of the parent merger is not binding on the IRS. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any described herein.

THE U.S. FEDERAL INCOME TAX RULES APPLICABLE TO THE PARENT MERGER AND TO REITS GENERALLY ARE HIGHLY TECHNICAL AND COMPLEX. HOLDERS OF COLONIAL COMMON SHARES ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE PARENT MERGER, THE OWNERSHIP OF COMMON STOCK OF THE COMBINED CORPORATION, AND THE COMBINED CORPORATION’S QUALIFICATION AS A REIT, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX LAWS, AND POTENTIAL CHANGES IN APPLICABLE TAX LAWS, IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES.

Tax Opinions from Counsel Regarding the Parent Merger

It is a condition to the completion of the parent merger that Hogan Lovells US LLP (or other counsel to Colonial reasonably acceptable to MAA) and Goodwin Procter LLP (or other counsel to MAA reasonably acceptable to Colonial) each renders a tax opinion to its client to the effect that the parent merger will constitute a reorganization within the meaning of Section 368(a) of the Code. Hogan Lovells US LLP and Goodwin Procter LLP counsel are providing opinions to Colonial and MAA, respectively, to similar effect in connection with the filing of this Registration Statement. Such opinions will be subject to customary exceptions, assumptions and qualifications, and will be based on representations made by Colonial and MAA regarding factual matters (including those contained in tax representation letters provided by Colonial and MAA), and covenants undertaken by Colonial and MAA. If any assumption or representation is inaccurate in any way, or any covenant is not complied with, the tax consequences of the parent merger could differ from those described in the tax opinions and in this discussion. These tax opinions represent the legal judgment of counsel rendering the opinion and are not binding on the IRS or the courts. No ruling from the IRS has been or will be requested in connection with the parent merger, and there can be no assurance that the IRS would not assert, or that a court would not sustain, a position contrary to the conclusions set forth in the tax opinions.

As noted and subject to the qualifications above, in the opinion of Hogan Lovells US LLP and Goodwin Procter LLP, the parent merger of Colonial with and into MAA will qualify as a reorganization within the meaning of Section 368(a) of the Code. Accordingly:

•

Colonial will not recognize any gain or loss as a result of the parent merger.

•

A U.S. holder will not recognize any gain or loss upon receipt of common stock of the Combined Corporation in exchange for its Colonial common shares in connection with the parent merger, except with respect to cash received in lieu of fractional shares of the Combined Corporation common stock, as discussed below.

•

A U.S. holder will have an aggregate tax basis in the Combined Corporation common stock received in the parent merger equal to the U.S. holder’s aggregate tax basis in its Colonial common shares surrendered pursuant to the parent merger, reduced by the portion of the U.S. holder’s tax basis in its Colonial common shares surrendered in the parent merger that is allocable to a fractional share of

124

Combined Corporation common stock. If a U.S. holder acquired any of its shares of Colonial common shares at different prices or at different times, Treasury Regulations provide guidance on how such U.S. holder may allocate its tax basis to shares of the Combined Corporation common stock received in the parent merger. U.S. holders that hold multiple blocks of Colonial common shares should consult their tax advisors regarding the proper allocation of their basis among shares of Combined Corporation common stock received in the parent merger under these Treasury Regulations.

•

The holding period of the Combined Corporation common stock received by a U.S. holder in connection with the parent merger will include the holding period of the Colonial common shares surrendered in connection with the parent merger.

•

Cash received by a U.S. holder in lieu of a fractional share of Combined Corporation common stock in the parent merger will be treated as if such fractional share had been issued in connection with the parent merger and then redeemed by the Combined Corporation, and such U.S. holder generally will recognize capital gain or loss with respect to such cash payment, measured by the difference, if any, between the amount of cash received and the U.S. holder’s tax basis in such fractional share. Such capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period in respect of such fractional share is greater than one year. Non-corporate U.S. holders are generally subject to tax on long-term capital gains at reduced rates under current law. The deductibility of capital losses is subject to certain limitations.

U.S. Federal Income Tax Consequences of the Parent Merger to Colonial and Colonial Shareholders (or MAA or MAA Shareholders) if the Parent Merger Does Not Qualify as a Reorganization

If the parent merger fails to qualify as a reorganization, then a Colonial shareholder generally would recognize gain or loss, as applicable, equal to the difference between:

•

the sum of the fair market value of the Combined Corporation common stock and cash in lieu of fractional shares of Combined Corporation common stock received by the Colonial shareholder in the parent merger; and

•

the Colonial shareholder’s adjusted tax basis in its Colonial common shares.

If the parent merger fails to qualify as a reorganization, so long as Colonial qualified as a REIT at the time of the parent merger, Colonial generally would not incur a U.S. federal income tax liability so long as Colonial has made distributions (which would be deemed to include for this purpose the fair market value of the Combined Corporation common stock issued pursuant to the parent merger) to Colonial shareholders in an amount at least equal to the net income or gain on the deemed sale of its assets to the Combined Corporation. In the event that such distributions were not sufficient to eliminate all of Colonial’s tax liability as a result of the deemed sale of its assets to Colonial, the Combined Corporation would be liable for any remaining tax owed by Colonial as a result of the parent merger.

Under the “investment company” rules under Section 368 of the Code, if both MAA and Colonial are “investment companies” under such rules, the failure of either Colonial or MAA to qualify as a REIT could cause the parent merger to be taxable to Colonial or MAA, respectively, and its shareholders.

If the parent merger fails to qualify as a reorganization and Colonial did not qualify as a REIT at the time of the parent merger, Colonial would generally recognize gain or loss on the deemed transfer of its assets to the Combined Corporation and the Combined Corporation, as its successor, could incur a very significant current tax liability and may be unable to qualify as a REIT.

If the parent merger fails to qualify as a reorganization as a result of MAA failing to qualify as a REIT at the time of the parent merger as a result of the “investment company” rules under Section 368 of the Code, it is possible that MAA might be treated, for certain purposes, as transferring its assets to Colonial in a taxable transaction in exchange for Combined Corporation common stock, followed by a deemed liquidation of MAA and a liquidating distribution of such Combined Corporation stock to MAA shareholders. In such a case, the Combined Corporation, as successor to MAA, may incur a very significant current tax liability and may be unable to qualify as a REIT.

125

Backup Withholding

Certain U.S. holders of Colonial common shares may be subject to backup withholding of U.S. federal income tax with respect to any cash received in lieu of fractional shares pursuant to the parent merger. Backup withholding generally will not apply, however, to a U.S. holder of Colonial common shares that furnishes a correct taxpayer identification number and certifies that it is not subject to backup withholding on IRS Form W-9 or is otherwise exempt from backup withholding and provides appropriate proof of the applicable exemption. Backup withholding is not an additional tax and any amounts withheld will be allowed as a refund or credit against the holder’s U.S. federal income tax liability, if any, provided that the holder timely furnishes the required information to the IRS.

Tax Opinions from Counsel Regarding REIT Qualification of Colonial and MAA

It is a condition to the obligation of MAA to complete the parent merger that MAA receive an opinion from Hogan Lovells US LLP (or other counsel to Colonial reasonably acceptable to MAA) to the effect that, for all taxable years commencing with Colonial’s taxable year ended December 31, 2004 through its taxable year which ends with the parent merger, Colonial has been organized and operated in conformity with the requirements for qualification and taxation as a REIT under the Code (including an exception for the consequences of the partnership merger). The opinion of Hogan Lovells US LLP (or such other counsel) will be subject to customary exceptions, assumptions and qualifications, and be based on representations made by Colonial and MAA regarding factual matters (including those contained in tax representation letters provided by Colonial and MAA), and covenants undertaken by Colonial and MAA, relating to the organization and operation of Colonial and its subsidiaries and MAA (and the Combined Corporation) and their subsidiaries.

It is a condition to the obligation of Colonial to complete the parent merger that Colonial receive an opinion from Baker, Donelson, Bearman, Caldwell & Berkowitz, PC (or other counsel to MAA reasonably acceptable to Colonial) to the effect that, for all taxable years commencing with MAA’s taxable year ended December 31, 2004, MAA has been organized and operated in conformity with the requirements for qualification and taxation as a REIT under the Code, and its past, current, and intended future organization and operations will permit MAA (as the Combined Corporation) to continue to qualify for taxation as a REIT under the Code for its taxable year that includes the parent merger and thereafter. The opinion of Baker, Donelson, Bearman, Caldwell & Berkowitz, PC (or such other counsel) will be subject to customary exceptions, assumptions and qualifications, and be based on representations made by Colonial and MAA regarding factual matters (including those contained in tax representation letters provided by Colonial and MAA), and covenants undertaken by Colonial and MAA, relating to the organization and operation of Colonial and its subsidiaries and MAA (and the Combined Corporation) and their subsidiaries.

Neither of the opinions described above will be binding on the IRS or the courts. The Combined Corporation intends to continue to operate in a manner to qualify as a REIT following the parent merger, but there is no guarantee that it will qualify or remain qualified as a REIT. Qualification and taxation as a REIT depend upon the ability of the Combined Corporation to meet, through actual annual (or, in some cases, quarterly) operating results, requirements relating to income, asset ownership, distribution levels and diversity of share ownership, and the various REIT qualification requirements imposed under the Code. Given the complex nature of the REIT qualification requirements, the ongoing importance of factual determinations and the possibility of future changes in the circumstances of the Combined Corporation, there can be no assurance that the actual operating results of the Combined Corporation will satisfy the requirements for taxation as a REIT under the Code for any particular tax year.

Tax Liabilities and Attributes Inherited from Colonial

If Colonial failed to qualify as a REIT for any of its taxable years for which the applicable period for assessment had not expired, Colonial would be liable for (and the Combined Corporation would be obligated to pay) U.S. federal income tax on its taxable income for such years at regular corporate rates, and, assuming the

126

parent merger qualified as a reorganization within the meaning of Section 368(a) of the Code, the Combined Corporation would be subject to tax on the built-in gain on each Colonial asset existing at the time of the parent merger if the Combined Corporation were to dispose of the Colonial asset for up to ten years following the parent merger. Such tax would be imposed at the highest regular corporate rate in effect at the date of the sale. Moreover, even if Colonial qualified as a REIT at all relevant times, the Combined Corporation similarly would be liable for other unpaid taxes (if any) of Colonial (such as the 100% tax on gains from any sales treated as “prohibited transactions” as discussed below in the discussion of the Combined Corporation’s status as a REIT). Moreover, and irrespective of whether Colonial qualified as a REIT, if Colonial were to incur tax liabilities as a result of the failure of the parent merger to qualify as a reorganization within the meaning of Section 368(a) of the Code, those tax liabilities would, as described above, be transferred to the Combined Corporation as a result of the parent merger.

Furthermore, after the parent merger and the partnership mergers the asset and gross income tests applicable to REITs will apply to all of the assets of the Combined Corporation, including the assets the Combined Corporation acquires from Colonial, and to all of the gross income of the Combined Corporation, including the income derived from the assets the Combined Corporation acquires from Colonial. As a result, the nature of the assets that the Combined Corporation acquires from Colonial and the gross income the Combined Corporation derives will be taken into account in determining the qualification of the Combined Corporation as a REIT. See “U.S. Federal Income Tax Consequences of the Parent Merger to Colonial and Colonial Shareholders (or MAA or MAA Shareholders) if the Parent Merger Does Not Qualify as a Reorganization” above.

Qualification as a REIT requires Colonial to satisfy numerous requirements, some on an annual and others on a quarterly basis, as described below with respect to Colonial. There are only limited judicial and administrative interpretations of these requirements, and qualification as a REIT involves the determination of various factual matters and circumstances which were not entirely within the control of Colonial.

Tax Liabilities and Attributes of MAA

If MAA failed to qualify as a REIT for any of its taxable years for which the applicable period for assessment had not expired, MAA would be liable for (and the Combined Corporation would be obligated to pay) U.S. federal income tax on its taxable income at regular corporate rates. Furthermore, MAA (and the Combined Corporation) would not be able to re-elect REIT status until the fifth taxable year after the first taxable year in which such failure occurred. See “U.S. Federal Income Tax Consequences of the Parent Merger to Colonial and Colonial Shareholders (or MAA or MAA Shareholders) if the Parent Merger Does Not Qualify as a Reorganization” above.

Material U.S. Federal Income Tax Considerations Applicable to Holders of the Combined Corporation Common Stock

This section summarizes the material U.S. federal income tax consequences generally resulting from the election of MAA to be taxed as a REIT and the ownership of common stock of the Combined Corporation. The sections of the Code and the corresponding Treasury Regulations that relate to qualification and operation as a REIT are highly technical and complex. The following sets forth the material aspects of the sections of the Code that govern the U.S. federal income tax treatment of a REIT and the holders of certain of its common stock under current law. This summary is qualified in its entirety by the applicable Code provisions, relevant rules and regulations promulgated under the Code, and administrative and judicial interpretations of the Code and these rules and regulations. Except as specifically noted, this discussion does not cover differences between current law and prior law applicable to REITs.

Taxation of REITs in General

MAA elected to be taxed as a REIT under Sections 856 through 860 of the Code commencing with its taxable year ended December 31, 1994. MAA believes that it has been organized and operated in a manner which

127

allows MAA and the Combined Corporation to qualify for taxation as a REIT under the Code commencing with the taxable year ended December 31, 1994. MAA currently intends to continue to be organized and operate in this manner. However, qualification and taxation as a REIT depend upon the ability of the Combined Corporation to meet the various qualification tests imposed under the Code, including through actual annual operating results, asset composition, distribution levels and diversity of stock ownership. Accordingly, no assurance can be given that MAA has been organized and has operated, or that the Combined Corporation will continue to be organized and operate, in a manner so as to qualify or remain qualified as a REIT.

Provided the Combined Corporation qualifies for taxation as a REIT, the Combined Corporation generally will be allowed to deduct dividends paid to its shareholders, and, as a result, the Combined Corporation generally will not be subject to U.S. federal income tax on that portion of its ordinary income and net capital gain that it currently distributes to its shareholders. The Combined Corporation expects to make distributions to its shareholders on a regular basis as necessary to avoid material U.S. federal income tax and to comply with the REIT requirements. See “—Annual Distribution Requirements” below.

Notwithstanding the foregoing, even if the Combined Corporation qualifies for taxation as a REIT, it nonetheless may be subject to U.S. federal income tax in certain circumstances, including the following:

•

The Combined Corporation will be required to pay U.S. federal income tax on its undistributed REIT taxable income, including net capital gain;

•

The Combined Corporation may be subject to the “alternative minimum tax”;

•

The Combined Corporation may be subject to tax at the highest corporate rate on certain income from “foreclosure property” (generally, property acquired by reason of default on a lease or indebtedness held by it);

•

The Combined Corporation will be subject to a 100% U.S. federal income tax on net income from “prohibited transactions” (generally, certain sales or other dispositions of property, sometimes referred to as “dealer property,” held primarily for sale to customers in the ordinary course of business) unless the gain is realized in a “taxable REIT subsidiary,” or TRS, or such property has been held by the Combined Corporation for at least two years and certain other requirements are satisfied;

•

If the Combined Corporation fails to satisfy the 75% gross income test or the 95% gross income test (discussed below), but nonetheless maintains its qualification as a REIT pursuant to certain relief provisions, the Combined Corporation will be subject to a 100% U.S. federal income tax on the greater of (i) the amount by which it fails the 75% gross income test or (ii) the amount by which it fails the 95% gross income test, in either case, multiplied by a fraction intended to reflect its profitability;

•

If the Combined Corporation fails to satisfy any of the asset tests, other than a failure of the 5% or the 10% asset tests that qualifies under the De Minimis Exception, and the failure qualifies under the General Exception, as described below under “—Qualification as a REIT—Asset Tests,” then the Combined Corporation will have to pay an excise tax equal to the greater of (i) $50,000 and (ii) an amount determined by multiplying the net income generated during a specified period by the assets that caused the failure by the highest U.S. federal income tax applicable to corporations;

•

If the Combined Corporation fails to satisfy any REIT requirements other than the income test or asset test requirements, described below under “—Qualification as a REIT—Income Tests” and “—Qualification as a REIT—Asset Tests,” respectively, and the Combined Corporation qualifies for a reasonable cause exception, then the Combined Corporation will have to pay a penalty equal to $50,000 for each such failure;

•

The Combined Corporation will be subject to a 4% nondeductible excise tax if certain distribution requirements are not satisfied;

•

The Combined Corporation may be required to pay monetary penalties to the IRS in certain circumstances, including if the Combined Corporation fails to meet record-keeping requirements

128

intended to monitor its compliance with rules relating to the composition of a REIT’s shareholders, as described below in “—Recordkeeping Requirements”;

•

If the Combined Corporation acquires any asset from a corporation which is or has been a C corporation in a transaction in which the basis of the asset in the Combined Corporation’s hands is less than the fair market value of the asset, in each case determined at the time it acquired the asset, and it subsequently recognizes gain on the disposition of the asset during the ten-year period beginning on the date on which it acquired the asset (or five year period for assets disposed of in calendar years 2012 and 2013), then it will be required to pay tax at the highest regular corporate tax rate on this gain to the extent of the excess of (a) the fair market value of the asset over (b) its adjusted basis in the asset, in each case determined as of the date on which it acquired the asset. The results described in this paragraph with respect to the recognition of gain assume that the C corporation will refrain from making an election to receive different treatment under applicable Treasury Regulations on its tax return for the year in which the Combined Corporation acquires the asset from the C corporation. The forgoing rules would apply to the assets acquired from Colonial in the parent merger if Colonial failed to qualify as a REIT for a period prior to the parent merger, the parent merger nonetheless qualified as a reorganization under Section 368(a) of the Code, and the Combined Corporation sold such assets within the applicable recognition periods. The IRS has issued proposed Treasury Regulations which would exclude from the application of this built-in gains tax any gain from the sale of property acquired by a REIT in an exchange under Section 1031 (a like kind exchange) or Section 1033 (an involuntary conversion) of the Code. The proposed Treasury Regulations described above will not be effective unless they are issued in their final form, and as of the date of this joint proxy statement/prospectus it is not possible to determine whether the proposed regulations will be finalized in their current form or at all;

•

The Combined Corporation will be required to pay a 100% tax on any redetermined rents, redetermined deductions, and excess interest. In general, redetermined rents are rents from real property that are overstated as a result of services furnished to any of its non-TRS tenants by one of its TRSs. Redetermined deductions and excess interest generally represent amounts that are deducted by a TRS for amounts paid to the Combined Corporation that are in excess of the amounts that would have been deducted based on arm’s-length negotiations; and

•

Income earned by the Combined Corporation’s TRSs or any other subsidiaries that are C corporations will be subject to tax at regular corporate rates.

No assurance can be given that the amount of any such U.S. federal income taxes will not be substantial. In addition, the Combined Corporation and its subsidiaries may be subject to a variety of taxes, including payroll taxes and state, local and foreign income, property and other taxes on assets and operations. The Combined Corporation could also be subject to tax in situations and on transactions not presently contemplated.

Qualification as a REIT

In General. The REIT provisions of the Code apply to a domestic corporation, trust, or association (i) that is managed by one or more trustees or directors, (ii) the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest, (iii) that properly elects to be taxed as a REIT and such election has not been terminated or revoked, (iv) that is neither a financial institution nor an insurance company, (v) that uses a calendar year for U.S. federal income tax purposes, (vi) that would be taxable as a domestic corporation but for the special Code provisions applicable to REITs and (vii) that meets the additional requirements discussed below.

Ownership Tests. Commencing with the Combined Corporation’s second REIT taxable year, (i) the beneficial ownership of the Combined Corporation common stock must be held by 100 or more persons during at least 335 days of a 12-month taxable year (or during a proportionate part of a taxable year of less than 12 months) for each of its taxable years and (ii) during the last half of each taxable year, no more than 50% in value

129

of the Combined Corporation’s shares may be owned, directly or indirectly, by or for five or fewer individuals, which we refer to as the 5/50 Test. Share ownership for purposes of the 5/50 Test is determined by applying the constructive ownership provisions of Section 544(a) of the Code, subject to certain modifications. The term “individual” for purposes of the 5/50 Test includes a private foundation, a trust providing for the payment of supplemental unemployment compensation benefits, and a portion of a trust permanently set aside or to be used exclusively for charitable purposes. A “qualified trust” described in Section 401(a) of the Code and exempt from tax under Section 501(a) of the Code generally is not treated as an individual for purposes of the 5/50 Test; rather, shares held by it are treated as owned proportionately by its beneficiaries.

The Combined Corporation’s charter restricts ownership and transfers of its shares that would violate these requirements, although these restrictions may not be effective in all circumstances to prevent a violation. In addition, the Combined Corporation will be deemed to have satisfied the 5/50 Test for a particular taxable year if it has complied with all the requirements for ascertaining the ownership of its outstanding shares in that taxable year and has no reason to know that it has violated the 5/50 Test.

Ownership of Interests in Entities Treated as Partnerships for U.S. Federal Income Tax Purposes. A REIT that is a partner in an entity treated as a partnership for U.S. federal income tax purposes (generally including any domestic unincorporated entity that has not elected to be taxed as a corporation and is not a “publicly traded partnership” or a “taxable mortgage pool”) will be deemed to own its proportionate share of the assets of the partnership and will be deemed to earn its proportionate share of the partnership’s income, based on its interest in partnership capital. In addition, the assets and gross income of the partnership retain the same character in the hands of the REIT for purposes of the gross income and asset tests applicable to REITs as described below. Thus, so long as MAA LP qualifies as a partnership for U.S. federal income tax purposes, the Combined Corporation’s proportionate share of the assets and items of income of MAA LP, including MAA LP’s share of assets and items of income of any subsidiaries that are partnerships for U.S. federal income tax purposes, are treated as assets and items of income of the Combined Corporation for purposes of applying the REIT income and asset tests described below. Unless otherwise noted, references to “partnership” in this discussion include any entity that is treated as a partnership for U.S. federal income tax purposes.

Ownership of Interests in Disregarded Subsidiaries. If a REIT owns a corporate subsidiary (including an entity which is treated as an association taxable as a corporation for U.S. federal income tax purposes) that is a “qualified REIT subsidiary,” the separate existence of that subsidiary is disregarded for U.S. federal income tax purposes. Generally, a qualified REIT subsidiary is a corporation, other than a TRS (discussed below), all of the capital stock of which is owned by the REIT (either directly or through other disregarded subsidiaries). For U.S. federal income tax purposes, all assets, liabilities and items of income, deduction and credit of the qualified REIT subsidiary will be treated as assets, liabilities and items of income, deduction and credit of the REIT itself. A qualified REIT subsidiary of the Company will not be subject to federal corporate income taxation, although it may be subject to state and local taxation in some states. Certain other entities also may be treated as disregarded entities for U.S. federal income tax purposes, generally including any domestic unincorporated entity that would be treated as a partnership if it had more than one owner. For U.S. federal income tax purposes, all assets, liabilities and items of income, deduction and credit of any such disregarded entity will be treated as assets, liabilities and items of income, deduction and credit of the owner of the disregarded entity.

Income Tests. In order to maintain qualification as a REIT, the Combined Corporation must annually satisfy two gross income requirements. First, at least 75% of its gross income (excluding gross income from prohibited transactions and certain other income and gains as described below) for each taxable year must be derived, directly or indirectly, from investments relating to real property or mortgages on real property or from certain types of temporary investments (or any combination thereof). Qualifying income for the purposes of this 75% gross income test generally includes: (a) rents from real property, (b) interest on debt secured by mortgages on real property or on interests in real property, (c) dividends or other distributions on, and gain from the sale of, shares in other REITs, (d) gain from the sale of real estate assets (other than gain from prohibited transactions), (e) income and gain derived from foreclosure property, and (f) income from certain types of temporary investments.

130

Second, in general, at least 95% of the Combined Corporation’s gross income (excluding gross income from prohibited transactions and certain other income and gains as described below) for each taxable year must be derived from the real property investments described above and from other types of dividends and interest, gain from the sale or disposition of shares or securities that are not dealer property, or any combination of the above.

Rents the Combined Corporation receives will qualify as rents from real property in satisfying the gross income requirements for a REIT described above only if several conditions are met. First, the amount of rent must not be based in whole or in part on the income or profits of any person. However, an amount received or accrued generally will not be excluded from the term “rents from real property” solely by reason of being based on a fixed percentage or percentages of receipts or sales. Second, rents received from a “related party tenant” will not qualify as rents from real property in satisfying the gross income tests unless the tenant is a TRS and either (i) at least 90% of the property is leased to unrelated tenants and the rent paid by the TRS is substantially comparable to the rent paid by the unrelated tenants for comparable space, or (ii) the property leased is a “qualified lodging facility,” as defined in Section 856(d)(9)(D) of the Code, or a “qualified health care property,” as defined in Section 856(e)(6)(D)(i), and certain other conditions are satisfied. A tenant is a related party tenant if the REIT, or an actual or constructive owner of 10% or more of the REIT’s stock, actually or constructively owns 10% or more of the interests in the assets or net profits of the tenant if the tenant is not a corporation, or, if the tenant is a corporation, 10% or more of the total combined voting power of all classes of stock entitled to vote or 10% or more of the total value of all classes of stock of the tenant. Third, if rent attributable to personal property, leased in connection with a lease of real property, is greater than 15% of the total rent received under the lease, then the portion of rent attributable to the personal property will not qualify as rents from real property.

Generally, for rents to qualify as rents from real property for the purpose of satisfying the gross income tests, the REIT may provide directly only an insignificant amount of services, unless those services are “usually or customarily rendered” in connection with the rental of real property and not otherwise considered “rendered to the occupant” under the applicable tax rules. Accordingly, the Combined Corporation may not provide “impermissible services” to tenants (except through an independent contractor from whom it derives no revenue and that meets other requirements or through a TRS) without giving rise to “impermissible tenant service income.” Impermissible tenant service income is deemed to be at least 150% of the direct cost to the REIT of providing the service. If the impermissible tenant service income exceeds 1% of the REIT’s total income from a property, then all of the income from that property will fail to qualify as rents from real property. If the total amount of impermissible tenant service income from a property does not exceed 1% of the Combined Corporation’s total income from the property, the services will not disqualify any other income from the property that qualifies as rents from real property, but the impermissible tenant service income will not qualify as rents from real property.

The Combined Corporation does not intend to charge rent that is based in whole or in part on the income or profits of any person or to derive rent from related party tenants, or rent attributable to personal property leased in connection with real property that exceeds 15% of the total rents from the real property if the treatment of any such amounts as non-qualified rent would jeopardize its status as a REIT. The Combined Corporation also does not intend to derive impermissible tenant service income that exceeds 1% of its total income from any property if the treatment of the rents from such property as nonqualified rents could cause it to fail to qualify as a REIT.

If the Combined Corporation fails to satisfy one or both of the 75% or the 95% gross income tests, it may nevertheless qualify as a REIT for a particular year if it is entitled to relief under certain provisions of the Code. Those relief provisions generally will be available if the failure to meet such tests is due to reasonable cause and not due to willful neglect and a schedule is filed describing each item of gross income for such year(s) in accordance with the applicable Treasury Regulations. It is not possible, however, to state whether in all circumstances these relief provisions could apply. As discussed above in “—Taxation of REITs in General,” even if these relief provisions were to apply, the Combined Corporation would be subject to U.S. federal income tax to the extent it fails to meet the 75% or 95% gross income tests or otherwise fails to distribute 100% of its net capital gain and taxable income.

131

Asset Tests. At the close of each quarter of its taxable year, the Combined Corporation must also satisfy four tests relating to the nature of its assets. First, real estate assets, cash and cash items, and government securities must represent at least 75% of the value of its total assets. Second, not more than 25% of its total assets may be represented by securities other than those in the 75% asset class. Third, of the investments that are not included in the 75% asset class and that are not securities of its TRSs, (i) the value of any one issuer’s securities owned by the Combined Corporation may not exceed 5% of the value of its total assets and (ii) the Combined Corporation may not own more than 10% by vote or by value of any one issuer’s outstanding securities. For purposes of the 10% value test, debt instruments issued by a partnership are not classified as “securities” to the extent of the Combined Corporation’s interest as a partner in such partnership (based on its proportionate share of the partnership’s equity interests and certain debt securities) or if at least 75% of the partnership’s gross income, excluding income from prohibited transactions, is qualifying income for purposes of the 75% gross income test. For purposes of the 10% value test, the term “securities” also does not include debt securities issued by another REIT, certain “straight debt” securities (for example, qualifying debt securities of a corporation of which the Combined Corporation owns no more than a de minimis amount of equity interest), loans to individuals or estates, and accrued obligations to pay rent. Fourth, securities of TRSs cannot represent more than 25% of a REIT’s total assets (20% in the case of taxable years beginning prior to January 1, 2009). Real estate assets for purposes of the REIT rules include stock in other REITs, but do not include stock in non-REIT companies.

The Combined Corporation will monitor the status of its assets for purposes of the various asset tests and will endeavor to manage its portfolio in order to comply at all times with such tests. If the Combined Corporation fails to satisfy the asset tests at the end of a calendar quarter, other than the first calendar quarter, the Combined Corporation will not lose its REIT status if one of the following exceptions applies:

•

the Combined Corporation satisfied the asset tests at the end of the preceding calendar quarter, and the discrepancy between the value of its assets and the asset test requirements arose from changes in the market values of its assets and was not wholly or partly caused by the acquisition of one or more non-qualifying assets; or

•

the Combined Corporation eliminates any discrepancy within 30 days after the close of the calendar quarter in which it arose.

Moreover, if the Combined Corporation fails to satisfy the asset tests at the end of a calendar quarter during a taxable year, it will not lose its REIT status if one of the following additional exceptions applies:

•

De Minimis Exception: The failure is due to a violation of the 5% or 10% asset tests referenced above and is “de minimis” (meaning that the failure is one that arises from ownership of assets the total value of which does not exceed the lesser of 1% of the total value of the Combined Corporation’s assets at the end of the quarter in which the failure occurred and $10 million), and the Combined Corporation either disposes of the assets that caused the failure or otherwise satisfies the asset tests within six months after the last day of the quarter in which the Combined Corporation’s identification of the failure occurred; or

•

General Exception: All of the following requirements are satisfied: (i) the failure is not due to a “de minimis” violation of the 5% or 10% asset tests (as defined above), (ii) the failure is due to reasonable cause and not willful neglect, (iii) the Combined Corporation files a schedule in accordance with Treasury Regulations providing a description of each asset that caused the failure, (iv) the Combined Corporation either disposes of the assets that caused the failure or otherwise satisfies the asset tests within six months after the last day of the quarter in which its identification of the failure occurred, and (v) the Combined Corporation pays an excise tax as described above in “—Taxation of REITs in General.”

Foreclosure Property. Foreclosure property is real property (including interests in real property) and any personal property incident to such real property (1) that is acquired by a REIT as a result of the REIT having bid in the property at foreclosure, or having otherwise reduced the property to ownership or possession by agreement

132

or process of law, after there was a default (or default was imminent) on a lease of the property or a mortgage loan held by the REIT and secured by the property, (2) for which the related loan or lease was made, entered into or acquired by the REIT at a time when default was not imminent or anticipated and (3) for which such REIT makes an election to treat the property as foreclosure property. Income and gain derived from foreclosure property is treated as qualifying income for both the 95% and 75% gross income tests. REITs generally are subject to tax at the maximum corporate rate (currently 35%) on any net income from foreclosure property, including any gain from the disposition of the foreclosure property, other than income that would otherwise be qualifying income for purposes of the 75% gross income test. Any gain from the sale of property for which a foreclosure property election has been made will not be subject to the 100% tax on gains from prohibited transactions described above, even if the property is held primarily for sale to customers in the ordinary course of a trade or business.

Debt Instruments. The Combined Corporation may hold or acquire mortgage, mezzanine, bridge loans and other debt investments. Interest income constitutes qualifying mortgage interest for purposes of the 75% gross income test (as described above) to the extent that the obligation upon which such interest is paid is secured by a mortgage on real property. If a REIT receives interest income with respect to a mortgage loan that is secured by both real property and other property, and the highest principal amount of the loan outstanding during a taxable year exceeds the fair market value of the real property on the date that it acquired or originated the mortgage loan, the interest income will be apportioned between the real property and the other collateral, and income from the arrangement will qualify for purposes of the 75% gross income test only to the extent that the interest is allocable to the real property. Loans that are modified generally will have to be retested using the fair market value of the collateral real property securing the loan as of the date the modification, unless the modification does not result in a deemed exchange of the unmodified note for the modified note for tax purposes, or the mortgage loan was in default or is reasonably likely to default and the modified loan substantially reduces the risk of default, in which case no re-testing in connection with the loan modification is necessary. Under IRS guidance, a loan may be treated as a qualifying real estate asset in an amount equal to the lesser of the fair market value of the loan or the fair market value of the real property securing the loan on the date the REIT acquired the loan. Although the guidance is not entirely clear, it appears that the non-qualifying portion of the mortgage loan will be equal to the portion of the loan’s fair market value that exceeds the value on the date of acquisition of the associated real property that is security for that loan.

The application of the REIT provisions of the Code to certain mezzanine loans, which are loans secured by equity interests in an entity that directly or indirectly owns real property rather than by a direct mortgage of the real property, is not entirely clear. A safe harbor in Revenue Procedure 2003-65 provides that if a mezzanine loan meets certain requirements then (i) the mezzanine loan will be treated as a qualifying real estate asset for purposes of the REIT asset tests and (ii) interest in respect of such mezzanine loan will be treated as qualifying mortgage interest for purposes of the 75% income test. To the extent the Combined Corporation acquires mezzanine loans that do not comply with this safe harbor, all or a portion of such mezzanine loans may not qualify as real estate assets or generate qualifying income and REIT status may be adversely affected. As such, the REIT provisions of the Code may limit the Combined Corporation’s ability to acquire mezzanine loans that it might otherwise desire to acquire.

Interests in a REMIC generally will be treated as real estate assets for purposes of the asset tests, and income derived from REMIC interests generally will be treated as qualifying income for purposes of the 75% and 95% gross income tests, except that if less than 95% of the assets of the REMIC are real estate assets, then the Combined Corporation will be treated as owning and receiving its proportionate share of the assets and income of the REMIC, with the result that only a proportionate part of the Combined Corporation’s interest in the REMIC and income derived from the interest will qualify for purposes of the assets and the 75% gross income test. Even if a loan is not secured by real property, or is undersecured, the income that it generates may nonetheless qualify for purposes of the 95% gross income test.

To the extent that a REIT derives interest income from a mortgage loan where all or a portion of the amount of interest payable is contingent, such income generally will qualify for purposes of the gross income tests only if

133

it is based upon the gross receipts or sales, and not the net income or profits, of the borrower. This limitation does not apply, however, (i) where the borrower leases substantially all of its interest in the property to tenants or subtenants, to the extent that the rental income derived by the borrower would qualify as rents from real property had the REIT earned the income directly, or (ii) if contingent interest is payable pursuant to a “shared appreciation mortgage” provision. A shared appreciation mortgage provision is any provision which is in connection with an obligation held by a REIT that is secured by an interest in real property, which entitles the REIT to a portion of the gain or appreciation in value of the collateral real property at a specified time. Any contingent interest earned pursuant to a shared appreciation mortgage provision shall be treated as gain from the sale of the underlying real property collateral for purposes of the REIT income tests.

Hedging Transactions. The Combined Corporation may enter into hedging transactions with respect to one or more of its assets or liabilities. Hedging transactions could take a variety of forms, including interest rate swaps or cap agreements, options, futures contracts, forward rate agreements or similar financial instruments. Except to the extent as may be provided by future Treasury Regulations, any income from a hedging transaction entered into after July 30, 2008 which is clearly and properly identified as such before the close of the day on which it was acquired, originated or entered into, including gain from the disposition or termination of such a transaction, will not constitute gross income for purposes of the 95% and 75% gross income tests, provided that the hedging transaction is entered into (i) in the normal course of business primarily to manage risk of interest rate or price changes or currency fluctuations with respect to indebtedness incurred or to be incurred to acquire or carry real estate assets or (ii) primarily to manage the risk of currency fluctuations with respect to any item of income or gain that would be qualifying income under the 75% or 95% income tests (or any property which generates such income or gain). In the case of a hedging transaction entered into on or prior to July 30, 2008 which is clearly and properly identified as such before the close of the day on which it was acquired, originated or entered into, the income from such transaction shall be excluded from the 95% income test, but shall be nonqualifying income for the 75% test, provided the hedging transaction is entered into to hedge debt incurred or to be incurred to acquire real estate assets. To the extent the Combined Corporation enters into other types of hedging transactions, the income from those transactions is likely to be treated as non-qualifying income for purposes of both the 75% and 95% gross income tests.

Foreign Investments. To the extent that the Combined Corporation holds or acquires any investments and, accordingly, pay taxes in other countries, taxes paid in non-U.S. jurisdictions may not be passed through to, or used by, the Combined Corporation’s shareholders as a foreign tax credit or otherwise. In addition, certain passive income earned by a non-U.S. taxable REIT subsidiary must be taken in account currently (whether or not distributed by the taxable REIT subsidiary) and may not be qualifying income under the 95% and 75% gross income tests.

Qualified Temporary Investment Income. Income derived by the Combined Corporation from certain types of temporary share and debt investments made with the proceeds of sales of the Combined Corporation’s stock or certain public debt offerings, not otherwise treated as qualifying income for the 75% gross income test, generally will nonetheless constitute qualifying income for purposes of the 75% gross income test for the year following the sale of such stock. More specifically, qualifying income for purposes of the 75% gross income test includes “qualified temporary investment income,” which generally means any income that is attributable to shares of stock or a debt instrument, is attributable to the temporary investment of new equity capital and certain debt capital, and is received or accrued during the one-year period beginning on the date on which the REIT receives such new capital. After such one year period, income from such investments will be qualifying income for purposes of the 75% income test only if derived from one of the other qualifying sources enumerated above. Also, for purposes of the REIT asset tests, the term “real estate assets” includes any property that is not otherwise a real estate asset and that is attributable to such temporary investment of new capital, but only if such property is comprised of shares or debt instruments, and only for the one-year period beginning on the date the REIT receives such new capital.

134

Annual Distribution Requirements

In order to qualify as a REIT, the Combined Corporation must distribute dividends (other than capital gain dividends) to its shareholders in an amount at least equal to (A) the sum of (i) 90% of its REIT taxable income, determined without regard to the dividends paid deduction and by excluding any net capital gain, and (ii) 90% of the net income (after tax), if any, from foreclosure property, minus (B) the sum of certain items of non-cash income. The Combined Corporation generally must pay such distributions in the taxable year to which they relate, or in the following taxable year if declared before the Combined Corporation timely files its tax return for such year and if paid on or before the first regular dividend payment after such declaration.

To the extent that the Combined Corporation does not distribute all of its net capital gain and taxable income, it will be subject to U.S. federal, state and local tax on the undistributed amount at regular corporate income tax rates. Furthermore, if the Combined Corporation should fail to distribute during each calendar year at least the sum of (i) 85% of its ordinary income for such year, (ii) 95% of its capital gain net income for such year, and (iii) 100% of any corresponding undistributed amounts from prior periods, it will be subject to a 4% nondeductible excise tax on the excess of such required distribution over the amounts actually distributed.

Under certain circumstances, the Combined Corporation may be able to rectify a failure to meet the distribution requirement for a year by paying “deficiency dividends” to its shareholders in a later year that may be included in its deduction for dividends paid for the earlier year. Thus, the Combined Corporation may be able to avoid being taxed on amounts distributed as deficiency dividends; however, the Combined Corporation will be required to pay interest based upon the amount of any deduction taken for deficiency dividends.

In addition, dividends the Combined Corporation pays must not be preferential. If a dividend is preferential, it will not qualify for the dividends paid deduction. To avoid paying preferential dividends, the Combined Corporation must treat every shareholder of the class of shares with respect to which it makes a distribution the same as every other shareholder of that class, and the Combined Corporation must not treat any class of shares other than according to its dividend rights as a class. Under certain technical rules governing deficiency dividends, the Combined Corporation could lose its ability to cure an under-distribution in a year with a subsequent year deficiency dividend if it pays preferential dividends. Accordingly, the Combined Corporation intends to pay dividends pro rata within each class, and to abide by the rights and preferences of each class.

The Combined Corporation may retain and pay income tax on net long-term capital gains received during the tax year. To the extent the Combined Corporation so elects, (i) each shareholder must include in its income (as long-term capital gain) its proportionate share of the Combined Corporation’s undistributed long-term capital gains, (ii) each shareholder is deemed to have paid, and receives a credit for, its proportionate share of the tax paid by the Combined Corporation on the undistributed long-term capital gains, and (iii) each shareholder’s basis in its shares of the Combined Corporation’s stock is increased by the included amount of the undistributed long-term capital gains less their share of the tax paid.

To qualify as a REIT, the Combined Corporation may not have, at the end of any taxable year, any undistributed earnings and profits accumulated in any non-REIT taxable year. In the event the Combined Corporation accumulates any non-REIT earnings and profits, the Combined Corporation intends to distribute its non-REIT earnings and profits before the end of its first REIT taxable year to comply with this requirement.

Failure to Qualify

If the Combined Corporation fails to qualify as a REIT and such failure is not an asset test or income test failure subject to the cure provisions described above, or the result of preferential dividends, the Combined Corporation generally will be eligible for a relief provision if the failure is due to reasonable cause and not willful neglect and the Combined Corporation pays a penalty of $50,000 with respect to such failure.

If the Combined Corporation fails to qualify for taxation as a REIT in any taxable year and no relief provisions apply, the Combined Corporation generally will be subject to tax (including any applicable alternative

135

minimum tax) on its taxable income at regular corporate rates. Distributions to the Combined Corporation’s shareholders in any year in which the Combined Corporation fails to qualify as a REIT will not be deductible by the Combined Corporation nor will they be required to be made. In such event, to the extent of the Combined Corporation’s current or accumulated earnings and profits, all distributions to its shareholders will be taxable as dividend income. Subject to certain limitations in the Code, corporate shareholders may be eligible for the dividends received deduction, and individual, trust and estate shareholders may be eligible to treat the dividends received from the Combined Corporation as qualified dividend income taxable as net capital gains, under the provisions of Section 1(h)(11) of the Code. Unless entitled to relief under specific statutory provisions, the Combined Corporation also will be ineligible to elect to be taxed as a REIT again prior to the fifth taxable year following the first year in which it failed to qualify as a REIT under the Code.

The Combined Corporation’s qualification as a REIT for U.S. federal income tax purposes will depend on it continuing to meet the various requirements summarized above governing the ownership of its outstanding shares, the nature of its assets, the sources of its income, and the amount of its distributions to its shareholders. Although the Combined Corporation intends to operate in a manner that will enable it to comply with such requirements, there can be no certainty that such intention will be realized. In addition, because the relevant laws may change, compliance with one or more of the REIT requirements may become impossible or impracticable.

Prohibited Transactions Tax

Any gain realized by the Combined Corporation on the sale of any property held as inventory or other property held primarily for sale to customers in the ordinary course of business, including its share of any such gain realized by its operating partnership and taking into account any related foreign currency gains or losses, will be treated as income from a “prohibited transaction” that is subject to a 100% penalty tax. Whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business depends upon all the facts and circumstances with respect to the particular transaction. However, the Code provides a safe harbor pursuant to which sales of properties held for at least two years and meeting certain other requirements will not give rise to prohibited transaction income.

The Combined Corporation may make sales that do not satisfy the “safe harbor” requirements described above and there can be no assurance that the IRS will not contend that one or more of these sales are subject to the 100% penalty tax. The 100% tax will not apply to gains from the sale of property realized through a TRS or other taxable corporation, although such income will be subject to tax at regular corporate income tax rates.

Recordkeeping Requirements

To avoid a monetary penalty, the Combined Corporation must request on an annual basis information from its shareholders designed to disclose the actual ownership of its outstanding shares.

Investments in TRSs

The Combined Corporation may own one or more subsidiaries intended to be treated as TRSs for federal income tax purposes. A TRS is a corporation in which a REIT directly or indirectly own shares and that jointly elects with the REIT to be treated as a TRS under Section 856(l) of the Code. In addition, if a TRS owns, directly or indirectly, securities representing 35% or more of the vote or value of a subsidiary corporation, that subsidiary will also be treated as a TRS of the REIT. A domestic TRS pays U.S. federal, state, and local income taxes at the full applicable corporate rates on its taxable income prior to payment of any dividends. A non-U.S. TRS with income from a U.S. trade or business or certain U.S. sourced income also may be subject to U.S. income taxes. A TRS owning property outside of the U.S. may pay foreign taxes. The taxes owed by a TRS could be substantial. To the extent that the Combined Corporation’s TRSs are required to pay U.S. federal, state, local, or foreign taxes, the cash available for distribution by the Combined Corporation will be reduced accordingly.

136

A TRS is permitted to engage in certain kinds of activities that cannot be performed directly by the Combined Corporation without jeopardizing the Combined Corporation’s qualification as a REIT. Certain payments made by any of the Combined Corporation’s TRSs to the Combined Corporation may not be deductible by the TRS (which could materially increase the TRS’s taxable income), and certain direct or indirect payments made by any of the Combined Corporation’s TRS to the Combined Corporation may be subject to 100% tax. In addition, subject to certain safe harbors, the Combined Corporation generally will be subject to a 100% tax on the amounts of any rents from real property, deductions, or excess interest received from a TRS that would be reduced through reapportionment under Section 482 of the Code in order to more clearly reflect the income of the TRS (and amounts protected from the 100% tax by reason of such safe harbor may nonetheless be reapportioned under Section 482).

Distributions that the Combined Corporation receives from a domestic TRS will be classified as dividend income to the extent of the current or accumulated earnings and profits of the TRS. Such distributions will generally constitute qualifying income for purposes of the 95% gross income test, but not under the 75% gross income test unless attributable to investments of certain new capital during the one-year period beginning on the date of receipt of the new capital.

REIT Subsidiaries

MAA LP may hold interests in one or more subsidiaries intended to qualify as REITs. Any such subsidiary REITs would need to satisfy the various REIT requirements discussed above on a stand-alone basis. Stock of any subsidiary qualifying as REIT will be a qualifying real estate asset for purposes of the assets tests , and any dividends received by the Combined Corporation from a subsidiary qualifying as a REIT and gains from sales of such subsidiary’s stock will be qualifying income for purposes of both the 95% and 75% gross income tests. If a subsidiary intended to qualify as a REIT failed to so qualify, the Combined Corporation would be treated as holding stock of a non-REIT, non-TRS corporate subsidiary, which could jeopardize the Combined Corporation’s status as a REIT.

Tax Aspects of MAA LP

In General. The Combined Corporation will own all or substantially all of its assets through MAA LP, and MAA LP in turn will a substantial portion of its assets through interests in various partnerships and limited liability companies.

Except in the case of subsidiaries that have elected REIT or TRS status, the Combined Corporation expects that MAA LP and the partnership and limited liability company subsidiaries MAA LP will be treated as partnerships or disregarded entities for U.S. federal income tax purposes. In general, entities that are classified as partnerships for U.S. federal income tax purposes are treated as “pass-through” entities which are not required to pay U.S. federal income tax. Rather, partners or members of such entities are allocated their share of the items of income, gain, loss, deduction and credit of the entity, and are potentially required to pay tax on that income without regard to whether the partners or members receive a distribution of cash from the entity. The Combined Corporation includes in its income its allocable share of the foregoing items for purposes of computing its REIT taxable income, based on the applicable partnership agreement. For purposes of applying the REIT income and asset tests, the Combined Corporation includes its pro rata share of the income generated by and the assets held by the partnerships and limited liability companies treated as partnerships for U.S. federal income tax purposes in which it owns an interest, including their shares of the income and assets of any subsidiary partnerships and limited liability companies treated as partnerships for U.S. federal income tax purposes based on its capital interests. See “—Taxation of REITs in General.”

The Combined Corporation’s ownership interests in such partnerships and limited liability companies involve special tax considerations, including the possibility that the IRS might challenge the status of these entities as partnerships or disregarded entities, as opposed to associations taxable as corporations, for U.S. federal

137

income tax purposes. If a partnership or limited liability company in which it owns an interest, or one or more of its subsidiary partnerships or limited liability companies, were treated as an association, it would be taxable as a corporation and would be required to pay an entity-level tax on its income. In this situation, the character of its assets and items of gross income would change, and could prevent the Combined Corporation from satisfying the REIT asset tests and/or the REIT income tests. See “—Qualification as a REIT—Asset Tests” and “—Qualification as a REIT—Income Tests.” This, in turn, could prevent it from qualifying as a REIT. See “—Failure to Qualify” for a discussion of the effect of its failure to meet these tests for a taxable year.

MAA believes that these partnerships and limited liability companies will be classified as partnerships or disregarded entities for U.S. federal income tax purposes, and the remainder of the discussion under this section “—Tax Aspects of MAA LP” is based on such classification.

Although a domestic unincorporated entity is generally treated as a partnership (if it has more than one owner) or a disregarded entity (if it has a single owner) for U.S. federal income tax purposes, in certain situations such an entity may be treated as a corporation for U.S. federal income tax purposes, including if the entity is a “publicly traded partnership” that does not qualify for an exemption based on the character of its income. A partnership is a “publicly traded partnership” under Section 7704 of the Code if:

(1)

interests in the partnership are traded on an established securities market; or

(2)

interests in the partnership are readily tradable on a “secondary market” or the “substantial equivalent” of a secondary market.

MAA LP currently takes the reporting position for U.S. federal income tax purposes that it is not a publicly traded partnership, and the Combined Corporation and MAA LP expect to continue to take that position after the partnership merger. There is a risk, however, that the right of a holder of operating partnership units to redeem the units for common stock could cause operating partnership units to be considered readily tradable on the substantial equivalent of a secondary market. Under the relevant Treasury regulations, interests in a partnership will not be considered readily tradable on a secondary market or on the substantial equivalent of a secondary market if the partnership qualifies for specified “safe harbors,” which are based on the specific facts and circumstances relating to the partnership. MAA and MAA LP believe that MAA LP will qualify for at least one of these safe harbors at all times in the foreseeable future, but cannot provide any assurance that MAA LP will continue to qualify for one of the safe harbors mentioned above.

If MAA LP is a publicly traded partnership, it will be taxed as a corporation unless at least 90% of its gross income has consisted and will consists of “qualifying income” under Section 7704 of the Code. Qualifying income is generally real property rents and other types of passive income. MAA and MAA LP believe that MAA LP will have sufficient qualifying income so that it would be taxed as a partnership, even if it were a publicly traded partnership. The income requirements applicable to REITs under the Code and the definition of qualifying income under the publicly traded partnership rules are very similar. Although differences exist between these two income tests, MAA and MAA LP do not believe that these differences have caused or will cause MAA LP not to satisfy the 90% gross income test applicable to publicly traded partnerships.

Allocations of Income, Gain, Loss and Deduction. A partnership or limited liability company agreement will generally determine the allocation of income and losses among partners or members. These allocations, however, will be disregarded for tax purposes if they do not comply with the provisions of Section 704(b) of the Code and the related Treasury Regulations. Generally, Section 704(b) of the Code and the related Treasury Regulations require that partnership and limited liability company allocations respect the economic arrangement of their partners or members. If an allocation is not recognized by the IRS for U.S. federal income tax purposes, the item subject to the allocation will be reallocated according to the partners’ or members’ interests in the partnership or limited liability company, as the case may be. This reallocation will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners or members with respect to such item. The allocations of taxable income and loss in each of the partnerships and limited liability companies in

138

which the Combined Corporation owns an interest are intended to comply with the requirements of Section 704(b) of the Code and the Treasury Regulations promulgated thereunder.

Tax Allocations With Respect to Contributed Properties. In general, when property is contributed to a partnership in exchange for a partnership interest, the partnership inherits the “carryover” tax basis of the contributing partner in the contributed property. Any difference between the fair market value and the adjusted tax basis of contributed property at the time of contribution is referred to as a “Book-Tax Difference.” Under Section 704(c) of the Code, income, gain, loss and deduction attributable to property with a Book-Tax Difference that is contributed to a partnership in exchange for an interest in the partnership must be allocated in a manner so that the contributing partner is charged with the unrealized gain or benefits from the unrealized loss associated with the property at the time of the contribution, as adjusted from time-to-time, so that, to the extent possible under the applicable method elected under Section 704(c) of the Code, the non-contributing partners receive allocations of depreciation and gain or loss for tax purposes comparable to the allocations they would have received in the absence of Book-Tax Differences. These allocations are solely for U.S. federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the partners or members. Similar tax allocations are required with respect to the Book-Tax Differences in the assets owned by a partnership when additional assets are contributed in exchange for a new partnership interest.

Contributions of appreciated property have been made to each of MAA LP and Colonial LP, and MAA LP may accept additional contributions from limited partners following the partnership merger. In addition, it is intended that, in connection with the partnership merger, Colonial LP be treated as contributing its properties to MAA LP in exchange for units in MAA LP and then distributing such units to the partners of Colonial LP in liquidation of Colonial LP. Moreover, the book value of the assets owned by MAA LP immediately prior to the partnership merger will be restated to current fair market value in connection with the partnership merger, thereby creating additional Book-Tax Differences. Consequently, the agreement of limited partnership of MAA LP will require such allocations to be made in a manner consistent with Section 704(c) of the Code. As a result of such tax allocations, the carryover basis of contributed assets in the hands of MAA LP and the absence of a basis step up in the partnership merger, certain partners of MAA LP (including the Combined Corporation) will be allocated lower amounts of depreciation and other deductions for tax purpose, and possibly greater amounts of taxable income in the event of sales, as compared to the partner’s share of such items for economic or book purposes. Thus, these rules may cause the Combined Corporation to recognize taxable income in excess of cash proceeds, which might adversely affect our ability to comply with the REIT distribution requirements. See “—Qualification as a REIT—Annual Distribution Requirements.”

U.S Federal Income Tax Considerations for U.S. Holders of the Combined Corporation Common Stock

Distributions. Distributions by the Combined Corporation, other than capital gain dividends, will constitute ordinary dividends to the extent of its current and accumulated earnings and profits as determined for U.S. federal income tax purposes. In general, these dividends will be taxable as ordinary income and will not be eligible for the dividends-received deduction for corporate U.S. holders. The Combined Corporation’s ordinary dividends generally will not qualify as “qualified dividend income” taxed as net capital gain for U.S. holders that are individuals, trusts, or estates. However, distributions to U.S. holders that are individuals, trusts, or estates generally will constitute qualified dividend income taxed as net capital gains to the extent the U.S. holder satisfies certain holding period requirements and to the extent the dividends are attributable to (i) qualified dividend income the Combined Corporation receives from C corporations, including its TRSs, (ii) the Combined Corporation’s undistributed earnings or built-in gains taxed at the corporate level during the immediately preceding year or (iii) any earnings and profits inherited from a C corporation in a tax-deferred reorganization or similar transaction, and provided the Combined Corporation properly designates the distributions as qualified dividend income. The Combined Corporation does not anticipate distributing a significant amount of qualified dividend income.

To the extent that the Combined Corporation makes a distribution in excess of its current and accumulated earnings and profits, the distribution will be treated first as a tax-free return of capital, reducing the tax basis in a

139

U.S. holder’s shares, and thereafter as capital gain realized from the sale of such shares to the extent the distribution exceeds the U.S. holder’s tax basis in the shares.

Dividends declared by the Combined Corporation in October, November or December and payable to a U.S. holder of record on a specified date in any such month shall be treated both as paid by the Combined Corporation and as received by the U.S. holder on December 31 of the year, provided that the dividend is actually paid during January of the following calendar year.

Distributions that are properly designated as capital gain dividends will be taxed as long-term capital gains (to the extent they do not exceed the Combined Corporation’s actual net capital gain for the taxable year) without regard to the period for which the U.S. holder has held its shares. However, corporate U.S. holders may be required to treat up to 20% of certain capital gain dividends as ordinary income. In addition, U.S. holders may be required to treat a portion of any capital gain dividend as “unrecaptured Section 1250 gain,” taxable at a maximum rate of 25%, if the Combined Corporation incurs such gain. Capital gain dividends are not eligible for the dividends-received deduction for corporations.

The REIT provisions of the Code do not require the Combined Corporation to distribute its long-term capital gain, and the Combined Corporation may elect to retain and pay income tax on its net long-term capital gains received during the taxable year. If the Combined Corporation so elects for a taxable year, its U.S. holders would include in income as long-term capital gains their proportionate share of retained net long-term capital gains for the taxable year as the Combined Corporation may designate. A U.S. holder would be deemed to have paid its share of the tax paid by the Combined Corporation on such undistributed capital gains, which would be credited or refunded to the U.S. holder. The U.S. holder’s basis in its shares would be increased by the amount of undistributed long-term capital gains (less the capital gains tax paid by the Combined Corporation) included in the U.S. holder’s long-term capital gains.

Passive Activity Loss and Investment Interest Limitations. The Combined Corporation’s distributions and gain from the disposition of its shares will not be treated as passive activity income and, therefore, U.S. holders will not be able to apply any “passive losses” against such income. With respect to non-corporate U.S. holders, the Combined Corporation’s dividends (to the extent they do not constitute a return of capital) that are taxed at ordinary income rates will generally be treated as investment income for purposes of the investment interest limitation; however, net capital gain from the disposition of shares of the Combined Corporation common stock (or distributions treated as such), capital gain dividends, and dividends taxed at net capital gains rates generally will be excluded from investment income except to the extent the U.S. holder elects to treat such amounts as ordinary income for U.S. federal income tax purposes. U.S. holders may not include in their own U.S. federal income tax returns any of the Combined Corporation’s net operating or net capital losses.

Sale or Disposition of Common Stock. In general, any gain or loss realized upon a taxable disposition of shares of the Combined Corporation common stock by a U.S. holder will be a long-term capital gain or loss if the shares have been held for more than one year and otherwise as a short-term capital gain or loss. However, any loss upon a sale or exchange of the shares by a U.S. holder who has held such shares for six months or less (after applying certain holding period rules) will be treated as a long-term capital loss to the extent of undistributed capital gains or distributions received by the U.S. holder from the Combined Corporation, each as required to be treated by such U.S. holder as long-term capital gain. All or a portion of any loss realized upon a taxable disposition of shares of the Combined Corporation common stock may be disallowed if other shares of its common stock are purchased within 30 days before or after the disposition.

Medicare Tax on Unearned Income. A U.S. holder that is an individual is subject to a 3.8% tax on the lesser of (1) the U.S. holder’s “net investment income” for the relevant taxable year and (2) the excess of the U.S. holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual’s circumstances). A U.S. holder that is an estate or trust that does not fall into a special class of trusts that is exempt from such tax is subject to

140

the same 3.8% tax on the lesser of its undistributed net investment income and the excess of its adjusted gross income over a certain threshold. A U.S. holder’s net investment income will include, among other things, dividends on and capital gains from the sale or other disposition of shares of the Combined Corporation. Prospective U.S. holders that are individuals, estates or trusts should consult their tax advisors regarding the effect, if any, of this Medicare tax on their ownership and disposition of the Combined Corporation common stock.

Taxation of U.S. Tax-Exempt Holders

In general, a tax-exempt organization is exempt from U.S. federal income tax on its income, except to the extent of its “unrelated business taxable income” or UBTI, which is defined by the Code as the gross income derived from any trade or business which is regularly carried on by a tax-exempt entity and unrelated to its exempt purposes, less any directly connected deductions and subject to certain modifications. For this purpose, the Code generally excludes from UBTI any gain or loss from the sale or other disposition of property (other than stock in trade or property held primarily for sale in the ordinary course of a trade or business), dividends, interest, rents from real property, and certain other items. However, a portion of any such gains, dividends, interest, rents, and other items generally is UBTI to the extent derived from debt-financed property, based on the amount of “acquisition indebtedness” with respect to such debt-financed property. Distributions that the Combined Corporation makes to a tax-exempt employee pension trust or other domestic tax-exempt holder or gains from the disposition of the Combined Corporation’s shares held as capital assets generally will not constitute UBTI unless the exempt organization’s shares are debt-financed property (e.g., the holder has borrowed to acquire or carry its shares). However, if the Combined Corporation is a “pension-held REIT,” this general rule will not apply to distributions to certain pension trusts that hold more than 10% (by value) of the Combined Corporation’s shares. The Combined Corporation will be treated as a “pension-held REIT” if (i) treating qualified trusts as individuals would cause the Combined Corporation to fail the 5/50 Test (as defined above) and (ii) the Combined Corporation is “predominantly held” by certain pension trusts. The Combined Corporation will be “predominantly held” if either (i) a single such pension trust holds more than 25% by value of the Combined Corporation’s shares or (ii) one or more such pension trusts, each owning more than 10% by value of the Combined Corporation’s shares, hold in the aggregate more than 50% by value of the Combined Corporation’s shares. In the event the Combined Corporation is a pension-held REIT, the percentage of any dividend received from it treated as UBTI would be equal to the ratio of (a) the gross UBTI (less certain associated expenses) earned by it (treating it as if it were a qualified trust and, therefore, subject to tax on UBTI) to (b) its total gross income (less certain associated expenses). A de minimis exception applies where the ratio set forth in the preceding sentence is less than 5% for any year; in that case, no dividends are treated as UBTI. There can be no assurance that the Combined Corporation will not be treated as a pension-held REIT. Before making an investment in shares of the Combined Corporation common stock, a tax-exempt holder should consult its tax advisors with regard to UBTI and the suitability of the investment in shares of the Combined Corporation’s common stock.

Social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, and qualified group legal services plans that are exempt from taxation under paragraphs (7), (9), (17), and (20), respectively, of Section 501(c) of the Code are subject to different UBTI rules, which generally will require them to characterize distributions from the Combined Corporation as UBTI. Before making an investment in shares of the Combined Corporation common stock, a tax-exempt holder should consult its tax advisors with regard to UBTI and the suitability of the investment in the Combined Corporation’s shares.

Taxation of Non-U.S. Holders.

The following is a summary of certain U.S. federal income tax consequences of the ownership and disposition of common stock of the Combined Corporation applicable to non-U.S. holders. The discussion addresses only selective and not all aspects of U.S. federal income taxation that may be material for non-U.S. holders and is for general information only.

141

Ordinary Dividends. The portion of dividends received by non-U.S. holders payable out of the Combined Corporation’s earnings and profits that are not attributable to gains from sales or exchanges of U.S. real property interests and which are not effectively connected with a U.S. trade or business of the non-U.S. holder generally will be treated as ordinary income and will be subject to withholding tax at the rate of 30%, unless reduced or eliminated by an applicable income tax treaty. Under some treaties, lower withholding rates do not apply to dividends from REITs.

In cases where the dividend income from a non-U.S. holder’s investment in the Combined Corporation common stock is, or is treated as, effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business, the non-U.S. holder generally will be subject to U.S. federal income tax at graduated rates, in the same manner as U.S. holders are taxed with respect to such dividends, and may also be subject to the 30% branch profits tax (or a lower rate of tax under the applicable income tax treaty) on the income after the application of the income tax in the case of a non-U.S. holder that is a corporation. The Combined Corporation plans to withhold U.S. income tax at the rate of 30% on the gross amount of any distribution paid to a non-U.S. holder (including any portion of any dividend that is payable in stock) that is neither a capital gain dividend nor a distribution that is attributable to gain from the sale or exchange of “United States real property interests” under the Foreign Investment in Real Property Tax Act of 1980, or FIRPTA, rules described below under “—Dispositions of Common Stock” unless either (i) a lower treaty rate applies and the non-U.S. holder files with the Combined Corporation any required IRS Form W-8 (for example, an IRS Form W-8BEN) evidencing eligibility for that reduced rate or (ii) the non-U.S. holder files with the Combined Corporation an IRS Form W-8ECI claiming that the distribution is effectively connected income. The balance of this discussion assumes that dividends that the Combined Corporation distributes to non-U.S. holders and gains non-U.S. holders recognize with respect to Combined Corporation shares are not effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business unless deemed to be effectively connected under FIRPTA as described below under “—Dispositions of Common Stock.”

Non-Dividend Distributions. Distributions by the Combined Corporation to non-U.S. holders that are not attributable to gains from sales or exchanges of U.S. real property interests and that exceed the Combined Corporation’s earnings and profits will be a non-taxable return of the non-U.S. holder’s basis in its shares and, to the extent in excess of the non-U.S. holder’s basis, gain from the disposition of such shares, the tax treatment of which is described below. If it cannot be determined at the time at which a distribution is made whether or not the distribution will exceed the Combined Corporation’s earnings and profits, the distribution may be subject to withholding at the rate applicable to dividends. A non-U.S. holder, however, may seek a refund from the IRS of any amounts withheld that exceed the non-U.S. holder’s actual U.S. federal income tax liability. If the Combined Corporation’s stock constitutes a U.S. real property interest, distributions in excess of the sum of the Combined Corporation’s earnings and profits plus the non-U.S. holder’s adjusted tax basis in the stock will be taxed under FIRPTA at the rate of tax, including any applicable capital gain rates, that would apply to a U.S. holder of the same type (e.g., an individual or a corporation, as the case may be), and the collection of the tax will be enforced by a withholding at a rate of 10% of the amount by which the distribution exceeds the non-U.S. holder’s share of the Combined Corporation’s earnings and profits. The amount withheld generally would be creditable against the non-U.S. holder’s U.S. federal income tax liability.

Capital Gain Dividends. Under FIRPTA, subject to the discussion below for 5% or smaller holders of regularly traded classes of stock, a distribution made by the Combined Corporation to a non-U.S. holder attributable to gains from dispositions of U.S. real property interests held by the Combined Corporation (directly or through pass-through subsidiaries) must be reported in U.S. federal income tax returns filed by, and are treated as effectively connected with a U.S. trade or business of, the non-U.S. holder. The term “U.S. real property interests” includes interests in U.S. real property and shares in U.S. corporations at least 50% of whose real estate and business assets consist of U.S. real property interests. Such gains are subject to federal income tax at the rates applicable to U.S. holders and, in the case of a non-U.S. holder that is a corporation, a 30% branch profits tax (or a lower rate of tax under the applicable income tax treaty). The Combined Corporation is required to withhold tax at a 35% rate from distributions that are attributable to gains from the sale or exchange of U.S. real property interests. The amount withheld generally would be creditable against the non-U.S. holder’s U.S. federal income tax liability.

142

Notwithstanding the foregoing discussion, capital gain dividends distributed to a non-U.S. holder who did not at any time during the one year period ending on the date of the distribution own more than 5% of a class of shares that is regularly traded on an established securities market located in the U.S. will not be subject to FIRPTA, but will be treated as ordinary dividends subject to the rules discussed above under “—Ordinary Dividends.”

Capital gain dividends that are not attributable to sales or exchanges of U.S. real property interests, generally are not subject to U.S. federal income tax unless (i) such distribution is effectively connected with a U.S. trade or business of the non-U.S. holder and, if certain treaties apply, is attributable to a U.S. permanent establishment of the non-U.S. holder, in which case the non-U.S. holder will be subject to net-basis U.S. federal income tax on the dividend as if the non-U.S. holder were a U.S. holder and, in the case of a non-U.S. holder that is a corporation, a 30% branch profits tax (or a lower rate of tax under the applicable income tax treaty), or (ii) such non-U.S. holder was present in the U.S. for 183 days or more during the taxable year and has a “tax home” in the U.S., in which case a 30% withholding tax would apply to the dividend.

However, notwithstanding that such dividends should only be subject to U.S. federal income taxation in those two instances, existing Treasury Regulations might be construed to require the Combined Corporation to withhold on such dividends in the same manner as capital gain dividends that are attributable to gain from the disposition of U.S. real property interests, generally at the rate of 35% of the dividend (although any amounts withheld generally would be creditable against the non-U.S. holder’s U.S. federal income tax liability).

Dispositions of Common Stock. Unless FIRPTA applies, or as otherwise set forth below, a sale or exchange of Combined Corporation shares by a non-U.S. holder generally will not be subject to U.S. federal income taxation. FIRPTA applies only if shares of the Combined Corporation common stock constitute a U.S. real property interest.

The Combined Corporation common stock will not constitute a U.S. real property interest if the Combined Corporation is a “domestically controlled qualified investment entity.” A domestically controlled qualified investment entity includes a REIT in which, at all times during a specified testing period, less than 50% in value of its outstanding shares are held directly or indirectly by non-U.S. holders. Because the Combined Corporation common stock will be publicly traded, no assurance can be given that the Combined Corporation will be, or that if it is it will remain, a domestically controlled qualified investment entity.

In the event that the Combined Corporation does not constitute a domestically controlled qualified investment entity, a non-U.S. holder’s sale of the Combined Corporation common stock nonetheless will generally not be subject to tax under FIRPTA as a sale of a U.S. real property interest, provided that (1) shares of the Combined Corporation common stock are “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market and (2) the selling non-U.S. holder owned, actually or constructively, 5% or less of the Combined Corporation’s outstanding common stock during the five-year period ending on the date of the sale or exchange (or, if shorter, the period during which the non-U.S. holder held the stock).

In addition, even if the Combined Corporation is a domestically controlled qualified investment entity, upon disposition of shares of the Combined Corporation, a non-U.S. holder may be treated as having gain from the sale or exchange of a U.S. real property interest if the non-U.S. holder (1) disposes of an interest in the Combined Corporation’s shares during the 30-day period preceding the ex-dividend date of a distribution, any portion of which, but for the disposition, would have been treated as gain from sale or exchange of a U.S. real property interest and (2) acquires, enters into a contract or option to acquire, or is deemed to acquire, other shares of the Combined Corporation common stock within 30 days after such ex-dividend date. The foregoing rules do not apply to a transaction if the 5% regularly traded test described above is satisfied with respect to the non-U.S. holder.

If gain on the sale of shares of the Combined Corporation common stock were subject to taxation under FIRPTA, the non-U.S. holder would be subject to the same treatment as a U.S. holder with respect to such gain, subject to applicable alternative minimum tax and a special alternative minimum tax in the case of nonresident alien individuals, and the purchaser of the shares could be required to withhold 10% of the purchase price and remit such amount to the IRS.

143

Gain from the sale of shares of the Combined Corporation common stock that would not otherwise be subject to FIRPTA will nonetheless be taxable in the U.S. to a non-U.S. holder if (i) such gain is effectively connected to a U.S. trade or business of the non-U.S. holder and, if certain treaties apply, is attributable to a U.S. permanent establishment of the non-U.S. holder, in which case the gain will be subject to net-basis U.S. federal income tax as if the non-U.S. holder were a U.S. holder and, in the case of a non-U.S. holder that is a corporation, a 30% branch profits tax (or a lower rate of tax under the applicable income tax treaty), or (ii) the non-U.S. holder is a nonresident alien individual who was present in the U.S. for 183 days or more during the taxable year and has a “tax home” in the U.S., in which case the nonresident alien individual will be subject to a 30% tax on the individual’s capital gain.

Information Reporting Requirements and Backup Withholding Tax

The Combined Corporation will report to its U.S. holders and to the IRS the amount of distributions paid during each calendar year, and the amount of tax withheld, if any. Under the backup withholding rules, a U.S. holder may be subject to backup withholding at a rate of 28% with respect to distributions paid, unless such U.S. holder (i) is a corporation or other exempt entity and, when required, proves its status or (ii) certifies under penalties of perjury that the taxpayer identification number the U.S. holder has furnished is correct and the U.S. holder is not subject to backup withholding and otherwise complies with the applicable requirements of the backup withholding rules. A U.S. holder that does not provide its correct taxpayer identification number also may be subject to penalties imposed by the IRS.

The Combined Corporation will also report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty. A non-U.S. holder may be subject to back-up withholding unless applicable certification requirements are met.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against such holder’s U.S. federal income tax liability, provided the required information is furnished to the IRS.

Other Withholding and Reporting Requirements under FATCA

The Foreign Account Tax Compliance Act provisions of the Code, enacted in 2010, which we refer to as FATCA, impose withholding taxes on certain types of payments to (i) foreign financial institutions that do not agree to comply with certain diligence, reporting and withholding obligations with respect to their U.S. accounts and (ii) non-financial foreign entities that do not identify (or confirm the absence of) substantial U.S. owners. The withholding tax of 30% would apply to dividends and the gross proceeds of a disposition of Combined Corporation stock paid to certain foreign entities unless various information reporting requirements are satisfied. Because the Combined Corporation may not know the extent to which a distribution is a dividend for U.S. federal income tax purposes at the time it is made, for purposes of these withholding rules the Combined Corporation may treat the entire distribution as a dividend. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing these withholding provisions may be subject to different rules.

For these purposes, a foreign financial institution generally is defined as any non-U.S. entity that (i) accepts deposits in the ordinary course of a banking or similar business, (ii) is engaged in the business of holding financial assets for the account of others, or (iii) is engaged or holds itself out as being engaged primarily in the business of investing, reinvesting, or trading in securities, partnership interests, commodities, or any interest in such assets. Withholding under this legislation (as modified pursuant to subsequent guidance) on withholdable payments to foreign financial institutions and non-financial foreign entities would apply after December 31, 2016

with respect to gross proceeds of a disposition of property that can produce U.S. source interest or dividends and would apply after June 30, 2014 with respect to other withholdable payments.

144

Legislative or Other Actions Affecting REITs

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. No assurance can be given as to whether, when, or in what form, the U.S. federal income tax laws applicable to the Combined Corporation and its shareholders may be enacted. Changes to the U.S. federal tax laws and interpretations of federal tax laws could adversely affect an investment in the Combined Corporation common stock.

State, Local and Foreign Tax

The Combined Corporation may be subject to state, local and foreign tax in states, localities and foreign countries in which it does business or owns property. The tax treatment applicable to the Combined Corporation and its shareholders in such jurisdictions may differ from the U.S. federal income tax treatment described above.

Accounting Treatment

MAA prepares its financial statements in accordance with GAAP. The parent merger will be accounted for by applying the acquisition method, which requires the identification of the acquirer, the determination of the acquisition date, the recognition and measurement, at fair value, of the identifiable assets acquired, liabilities assumed and any noncontrolling interest in the consolidated subsidiaries of the acquiree and recognition and measurement of goodwill or a gain from a bargain purchase. The accounting guidance for business combinations, referred to as ASC 805, provides that in a business combination involving the exchange of equity interests, the entity issuing the equity interests is usually the acquirer; however, all pertinent facts and circumstances must be considered, including the relative voting rights of the shareholders of the constituent companies in the combined entity, the composition of the board of directors and senior management of the combined entity, the relative size of the company and the terms of the exchange of equity interests in the business combination, including payment of a premium.

Based on the fact that MAA is the entity issuing the equity securities, that continuing MAA equity holders will own approximately 56% of the issued and outstanding common shares of the Combined Corporation, assuming the conversion of all limited partnership units of MAA LP held by existing limited partners of MAA LP to shares of Combined Corporation common stock, and former Colonial equity holders will own approximately 44% of the issued and outstanding shares of common stock of the Combined Corporation, assuming the conversion of all limited partnership units issued by MAA LP to former limited partners of Colonial LP to shares of Combined Corporation common stock, and that MAA board members and senior management will represent the majority of the board and senior management of the Combined Corporation, and based on the terms of the parent merger, with Colonial shareholders receiving a premium (as of the trading day immediately preceding the merger announcement) over the fair market value of their shares on such date, MAA is considered the acquirer for accounting purposes. Therefore, MAA will recognize and measure, at fair value, the identifiable assets acquired, liabilities assumed and any noncontrolling interests in the consolidated subsidiaries of Colonial, and MAA will recognize and measure goodwill and any gain from a bargain purchase, in each case, upon completion of the parent merger.

Exchange of Shares in the Parent Merger

MAA has appointed American Stock Transfer & Trust Company, or the exchange agent, to act as the exchange agent for the exchange of Colonial common shares for shares of MAA common stock. As promptly as practicable after the effective time of the parent merger, the exchange agent will send to each holder of record of Colonial common shares at the effective time of the parent merger who holds Colonial common shares in certificated or book-entry form a letter of transmittal and instructions for effecting the exchange of Colonial common share certificates or book-entry shares for the merger consideration the holder is entitled to receive under the merger agreement. Upon surrender of share certificates or book-entry shares for cancellation along

145

with the executed letter of transmittal and other documents described in the instructions, a Colonial shareholder will receive any whole shares of MAA common stock such holder is entitled to receive and cash in lieu of any fractional shares of MAA common stock such holder is entitled to receive. After the effective time of the parent merger, Colonial will not register any transfers of Colonial common shares.

MAA shareholders need not take any action with respect to their stock certificates or book-entry shares.

Dividends

Each company plans to continue its current dividend policy until the closing of the mergers, except that MAA and Colonial will coordinate so that their respective quarterly dividends declared following the execution of the merger agreement will have the same payment dates and record dates. MAA currently pays a quarterly dividend equating to $0.695 per share and Colonial currently pays a quarterly dividend equating to $0.21 per share. Following the closing of the mergers, MAA expects to continue its current dividend policy for shareholders of the Combined Corporation, subject to the discretion of the Combined Corporation’s board of directors, which reserves the right to change the Combined Corporation’s dividend policy at any time and for any reason.

Delisting and Deregistration of Colonial Common Shares

After the parent merger is completed, the Colonial common shares currently listed on the NYSE will cease to be listed on the NYSE and will be deregistered under the Exchange Act.

Litigation Relating to the Mergers

On June 19, 2013, a putative class action and derivative lawsuit was filed in the Circuit Court for Jefferson County, Alabama against and purportedly on behalf of Colonial captioned Williams v. Colonial Properties Trust, et al. The complaint names as defendants Colonial, the members of the Colonial Board, Colonial, LP, MAA, MAA LP and OP Merger Sub and alleges that the trustees of Colonial breached their fiduciary duties by engaging in an unfair process leading to the merger agreement, failing to secure and obtain the best price reasonable for Colonial shareholders, allowing preclusive deal protection devices in the merger agreement, and by engaging in conflicted actions. The complaint alleges that Colonial LP, MAA, MAA LP and OP Merger Sub aided and abetted those breaches of fiduciary duties. The complaint seeks a declaration that defendants have breached their fiduciary duties or aided and abetted such breaches and that the merger agreement is unlawful and unenforceable, an order enjoining the consummation of the mergers, direction of the Colonial trustees to exercise their fiduciary duties to obtain a transaction that is in the best interests of Colonial, rescission of the mergers in the event they are consummated, an award of costs and disbursements, including reasonable attorneys’ and experts’ fees, and other relief. On July 2, 2013, plaintiff moved for expedited fact discovery and for an expedited schedule for filing and hearing a preliminary motion to enjoin the mergers; on July 11, 2013, defendants opposed those motions and moved to stay fact discovery. On July 11, 2013, defendants also moved to dismiss the complaint for failure to state a claim upon which relief can be granted on the grounds that (1) the claims against the Colonial trustees are derivative and not direct, and plaintiff did not comply with Alabama law on serving notice of the claims on Colonial prior to filing; and (2) Alabama law does not recognize a cause of action in aiding and abetting a breach of fiduciary duty. The Court has scheduled a motions hearing for August 8, 2013.

THE MERGER AGREEMENT

This section of this joint proxy statement/prospectus summarizes the material provisions of the merger agreement, which is attached as Annex A to this joint proxy statement/prospectus and is incorporated herein by reference. As a shareholder, you are not a third party beneficiary of the merger agreement and therefore you may not directly enforce any of its terms and conditions.

This summary may not contain all of the information about the merger agreement that is important to you. MAA and Colonial urge you to carefully read the full text of the merger agreement because it is the legal document that governs the mergers. The merger agreement is not intended to provide you with any factual information about MAA or Colonial. In particular, the assertions embodied in the representations and warranties contained in the merger agreement (and summarized below) are qualified by information each of MAA and Colonial filed with the SEC prior to the effective date of the merger agreement, as well as by certain disclosure letters each of the parties delivered to the other in connection with the signing of the merger agreement, that modify, qualify and create exceptions to the representations and warranties set forth in the merger agreement. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may apply contractual standards of materiality in a way that is different from what may be viewed as material by investors or that is different from standards of materiality generally applicable under the U.S. federal securities laws or may not be intended as statements of fact, but rather as a way of allocating risk among the parties to the merger agreement. The representations and warranties and other provisions of the merger agreement and the description of such provisions in this document should not be read alone but instead should be read in conjunction with the other information contained in the reports, statements and filings that each of MAA and Colonial file with the SEC and the other information in this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 201.

MAA and Colonial acknowledge that, notwithstanding the inclusion of the foregoing cautionary statements, each of them is responsible for considering whether additional specific disclosures of material information regarding material contractual provisions are required to make the statements in this joint proxy statement/prospectus not misleading.

Form, Effective Time and Closing of the Mergers

The merger agreement provides for the combination of Colonial and MAA through the merger of Colonial with and into MAA, with MAA surviving the parent merger upon the terms and subject to the conditions set forth in the merger agreement. The parent merger will become effective upon the later of such time as the articles of merger have been accepted for record by the Office of the Secretary of State for the State of Alabama or the articles of merger have been accepted for record by the Secretary of State of the State of Tennessee or at a later date and time agreed to by MAA and Colonial (not to exceed 30 days from the date the articles of merger are accepted for record). The merger agreement also provides for the merger, prior to the parent merger, of OP Merger Sub, a subsidiary of MAA LP, with and into Colonial LP with Colonial LP continuing as the surviving entity and an indirect wholly-owned subsidiary of MAA LP. The partnership merger will become effective upon such time as the certificate of merger has been filed with the Secretary of State for the State of Delaware or at a later date and time agreed to by MAA and Colonial (not to exceed 30 days from the date the certificate of merger is accepted for record). MAA and Colonial have agreed to cause the effective time of the partnership merger to occur prior to the effective time of the parent merger.

The merger agreement provides that the closing of the parent merger will take place at the date and time mutually agreed upon by MAA and Colonial but in no event later than the third business day following the date on which the last of the conditions to closing of the parent merger (described below under “—Conditions to Completion of the Mergers”) have been satisfied or waived (other than the conditions that by their terms are to be satisfied at the closing of the parent merger, but subject to the satisfaction or waiver of those conditions), although MAA may elect in its reasonable discretion to accelerate or delay the date of closing to the last business

147

day of the month in which the last of the conditions to closing of the parent merger have been satisfied or waived (provided the date of closing does not occur less than two business days and no more than 15 calendar days after the date on which all conditions to closing have been satisfied or waived).

The MAA parties and the Colonial parties have agreed to cooperate reasonably with each other to consider any reasonable changes requested by the other parties regarding the structure of the mergers and the other transactions contemplated by the merger agreement so long as the changes do not have certain effects.

Organizational Documents of the Combined Corporation

The MAA charter and MAA bylaws as in effect immediately prior to the effective time of the parent merger will continue to be in effect following the parent merger as the charter and bylaws of the Combined Corporation.

MAA has agreed to cause the limited partnership agreement of MAA LP to be amended and restated in all material respects in the form attached to this joint proxy statement/prospectus as Annex I no later than the effective time of the partnership merger and the limited partnership agreement of MAA LP, as so amended and restated, will be the limited partnership agreement of MAA LP following the partnership merger.

Board of Directors of the Combined Corporation

Merger Consideration; Effects of the Parent Merger and the Partnership Merger

Merger Consideration

At the effective time of the parent merger and by virtue of the parent merger, each outstanding Colonial common share (other than shares held by any wholly owned subsidiary of Colonial or by MAA or any of its subsidiaries and other than shares with respect to which dissenters’ rights have been properly exercised and not withdrawn under applicable law) will be converted into the right to receive 0.360, which is referred to herein as the exchange ratio, shares of MAA common stock, which is referred to herein as the merger consideration. No fractional shares of MAA common stock will be issued. Instead of fractional shares, Colonial shareholders will receive cash, without interest, in an amount determined by multiplying the fractional interest of MAA common stock to which the holder would otherwise be entitled by the volume weighted average price of MAA common stock for the 10 trading days immediately prior to the closing date, starting with the opening of trading on the first trading day to the closing of the second to last trading day prior to the closing date, as reported by Bloomberg.

At the effective time of the partnership merger, each outstanding limited partnership unit in Colonial LP will automatically be converted into 0.360 limited partnership units in MAA LP and Colonial LP will become an indirect wholly owned subsidiary of MAA LP.

148

Procedures for Surrendering Colonial Share Certificates

The conversion of Colonial common shares into the right to receive the merger consideration will occur automatically at the effective time of the parent merger. In accordance with the merger agreement, MAA has appointed an exchange agent to handle the payment and delivery of the merger consideration and the cash payments to be delivered in lieu of fractional shares. At the effective time of the parent merger, the Combined Corporation will deliver to the exchange agent evidence of the MAA common stock in book-entry form sufficient to pay the merger consideration and cash in an amount sufficient to pay for any fractional shares. As soon as reasonably practicable after the effective time, but in no event later than two business days thereafter, the Combined Corporation will cause the exchange agent to mail (and make available for collection by hand) to each record holder of Colonial common shares, a letter of transmittal and instructions explaining how to surrender Colonial common share certificates to the exchange agent.

Each Colonial shareholder that surrenders its stock certificate to the exchange agent together with a duly completed letter of transmittal, and each Colonial shareholder that holds book-entry Colonial common shares, will receive the merger consideration due to such shareholder (including cash in lieu of any fractional shares). After the effective time of the parent merger, each certificate that previously represented Colonial common shares will only represent the right to receive the merger consideration into which those Colonial common shares have been converted.

Assumption of Colonial Equity Incentive Plans by MAA

Withholding

All payments under the merger agreement are subject to applicable withholding requirements.

Dissenters’ Rights

Holders of Colonial common shares are entitled to dissent and demand payment for their shares at “fair value” plus accrued interest. See “Dissenters’ Rights” beginning on page 173. MAA’s obligation to close the mergers will be conditioned on holders of no more than 15% of Colonial common shares properly perfecting their right to dissent and demand cash payment for their shares.

Representations and Warranties

The merger agreement contains a number of representations and warranties made by the MAA parties, on the one hand, and the Colonial parties, on the other hand. The representations and warranties were made by the parties as of the date of the merger agreement and do not survive the effective time of the mergers. Certain of these representations and warranties are subject to specified exceptions and qualifications contained in the merger agreement and qualified by information each of MAA and Colonial filed with the SEC prior to the date of the merger agreement and in the disclosure letters delivered in connection with the merger agreement.

Definition of “Material Adverse Effect”

Many of the representations of the MAA parties and the Colonial parties are qualified by a “material adverse effect” standard (that is, they will not be deemed to be untrue or incorrect unless their failure to be true or correct, individually or in the aggregate, would reasonably be expected to have a material adverse effect). For the purposes of the merger agreement, “material adverse effect” means any event, circumstance, change or effect (i) that is material and adverse to the business, assets, properties, financial condition or results of operations of MAA and its subsidiaries, taken as a whole, or Colonial and its subsidiaries, taken as a whole, as the case may be, or (ii) that will, or would reasonably be expected to, prevent or materially impair the ability of the MAA parties or the Colonial parties, as the case may be, to consummate the mergers in the manner contemplated by the merger agreement before December 31, 2013. However, for purposes of clause (i) above, any event, circumstance, change or effect will not be considered a material adverse effect to the extent arising out of or resulting from the following:

•

any failure of MAA or Colonial, as applicable, to meet any internal or external projections or forecasts or any estimates of earnings, revenues, or other metrics for any period (except any event, circumstance, change or effect giving rise to such failure may be taken into account in determining whether there has been a material adverse effect);

151

•

any events, circumstances, changes or effects that affect the multifamily residential real estate REIT industry generally;

•

any changes in the United States or global economy or capital, financial or securities markets generally, including changes in interest or exchange rates;

•

any changes in the legal or regulatory conditions;

•

the commencement, escalation or worsening of a war or armed hostilities or the occurrence of acts of terrorism or sabotage;

•

the negotiation, execution or announcement of the merger agreement, or the consummation or anticipation of consummation of the mergers or the other transactions contemplated by the merger agreement;

•

the taking of any action expressly required by, or the failure to take any action expressly prohibited by, the merger agreement, or the taking of any action at the written request or with the prior written consent of an executive officer of the other party;

•

earthquakes, hurricanes, floods or other natural disasters;

•

any damage or destruction of any MAA or Colonial property that is substantially covered by insurance; or

•

changes in law or GAAP;

which, (i) in the case of the second, third, fourth, fifth and tenth bullet points above, such changes do not materially disproportionately affect MAA and its subsidiaries, taken as a whole, or Colonial and its subsidiaries, taken as a whole, as applicable, relative to other similarly situated participants in the multifamily residential real estate REIT industry in the United States and (ii) in the case of the eighth bullet point above, such changes do not materially disproportionately affect MAA and its subsidiaries, taken as a whole, or Colonial and its subsidiaries, taken as a whole, as applicable, relative to other participants in the multifamily residential real estate REIT industry in the geographic regions in which MAA and its subsidiaries, or Colonial and its subsidiaries, as applicable, operate or own or lease properties.

No Solicitation of Transactions

Each of MAA and Colonial will not, nor will it permit any of its subsidiaries to, authorize or permit any of its officers, trustees, directors or employees to, and will use its reasonable best efforts to cause its and its subsidiaries’ representatives not to, directly or indirectly, (i) initiate, solicit or knowingly encourage or knowingly facilitate any inquiries or the making of any proposal or offer by or with a third party with respect to an Acquisition Proposal (as defined below), (ii) engage in any negotiations concerning, or provide any confidential information or data to any person relating to an Acquisition Proposal, or knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal, (iii) approve or execute or enter into any letter of intent, agreement in principle, merger agreement, asset purchase or share exchange agreement, option agreement or other similar agreement related to any Acquisition Proposal, or (iv) propose publicly or agree to do any of the foregoing.

156

Notwithstanding the restrictions set forth above, the merger agreement provides that, at any time prior to the approval of the parent merger at their respective shareholder meetings, each of the Colonial Board and the MAA Board is permitted, subject to first entering into a confidentiality agreement having provisions that are no less favorable to those contained in the confidentiality agreement between MAA and Colonial, to engage in discussions and negotiations with, or provide any nonpublic information or data to, any person in response to an unsolicited bona fide written Acquisition Proposal by such person made after June 3, 2013 that did not result from a breach of the no solicitation provisions of the merger agreement and which the MAA Board or the Colonial Board, as applicable, concludes in good faith (after consultation with outside legal counsel and financial advisors) constitutes or is reasonably likely to lead to a Superior Proposal (as defined below), if and only to the extent that the MAA Board or the Colonial Board, as applicable, conclude in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with their duties under applicable law. Colonial and MAA, as applicable, will provide the other party with a copy of any nonpublic information or data provided to a third party prior to or simultaneously with furnishing such information to such third party.

Each party must notify the other party promptly (but in no event later than one business day) after receipt of any Acquisition Proposal, or any request for nonpublic information relating to such party or any of its subsidiaries by any person that informs such party or any of its subsidiaries that it is considering making, or has made, an Acquisition Proposal, or any inquiry from any person seeking to have discussions or negotiations with such party relating to a possible Acquisition Proposal. The notice will be made orally and confirmed in writing, and will indicate the identity of the person making the Acquisition Proposal, inquiry or request and the material terms and conditions of any inquiries, proposals or offers (including a copy thereof if in writing and any related documentation or correspondence). Each party will also promptly, and in any event within one business day, notify the other party, orally and in writing, if it enters into discussions or negotiations concerning any Acquisition Proposal or provides nonpublic information or data to any person and keep the other party informed in all material respects of the status and terms of any such proposals, offers, discussions or negotiations on a current basis, including by providing a copy of all material documentation or correspondence relating thereto.

Except as described below, neither the MAA Board, the Colonial Board, nor any committee thereof, will withhold, withdraw or modify in any manner adverse to the other party, or propose publicly to withhold, withdraw or modify in any manner adverse to the other party, the approval, recommendation or declaration of advisability by the MAA Board or the Colonial Board, as applicable, or any such committee thereof with respect to the merger agreement or the transactions contemplated thereby, which is referred to herein as a Change in Recommendation.

Notwithstanding the foregoing, with respect to an Acquisition Proposal, the MAA Board or the Colonial Board, as applicable, may make a Change in Recommendation (and in the event that the MAA Board or the Colonial Board, as applicable, determines the Acquisition Proposal to be a Superior Proposal, terminate the merger agreement), if and only if (i) an unsolicited bona fide written Acquisition Proposal (that did not result from a breach of the no solicitation provisions of the merger agreement) is made to MAA or Colonial, as applicable, and is not withdrawn, (ii) the MAA Board or the Colonial Board, as applicable, has concluded in good faith (after consultation with outside legal counsel and financial advisors) that such Acquisition Proposal constitutes a Superior Proposal, (iii) the directors of MAA and the trustees of Colonial, as applicable, have concluded in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with their duties under applicable law, (iv) four business days, which is referred to herein as the notice period, has elapsed since the party proposing to take such action has given written notice to the other party advising the other party that it intends to take such action and specifying in reasonable detail the reasons therefor, including the terms and conditions of any such Superior Proposal that is the basis of the proposed action, which is referred to as the notice of recommendation change, (v) during such notice period, the notifying party has considered and, at the reasonable request of the other party, engaged in good faith discussions with the other party regarding, any adjustment or modification of the terms of the merger agreement proposed by the other party, and (vi) the directors or trustees of the party proposing to take such action, following such notice period, again reasonably determine in good faith (after consultation with outside legal counsel, and taking into account any adjustment or

157

modification of the terms of the merger agreement proposed by the other party) that failure to do so would be inconsistent with their duties under applicable law. Upon any material amendment to the Superior Proposal giving rise to the notice, the notifying party is required to deliver a new notice and commence a new negotiation period of four business days.

For the purposes of the merger agreement, in circumstances not involving or relating to an Acquisition Proposal, the MAA Board or the Colonial Board, as applicable, may make a Change in Recommendation if and only if (i) a material development or change in circumstances has occurred or arisen after June 3, 2013 that was neither known to such party nor reasonably foreseeable as of June 3, 2013 (and which change or development does not relate to an Acquisition Proposal), (ii) the directors or trustees of the party proposing to take such action have first reasonably determined in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with their duties under applicable law, (iii) four business days, which is referred to herein as the intervening event notice period, will have elapsed since the party proposing to take such action has given a notice of recommendation change to the other party advising that the notifying party intends to take such action and specifying in reasonable detail the reasons therefor, (iv) during the four business day period, the notifying party has considered and, at the reasonable request of the other party, engaged in good faith discussions with the other party regarding, any adjustment or modification of the terms of the merger agreement proposed by the other party, and (v) the directors or trustees, as applicable, of the party proposing to take such action, following such intervening event notice period, again reasonably determine in good faith (after consultation with outside legal counsel, and taking into account any adjustment or modification of the terms of the merger agreement proposed by the other party) that failure to do so would be inconsistent with their duties under applicable law. In the event the MAA Board or the Colonial Board, as applicable, does not make a Change in Recommendation following such four business day period, but thereafter determines to make a Change in Recommendation in circumstances not involving an Acquisition Proposal, the foregoing procedures shall apply anew and shall also apply to any subsequent withdrawal, amendment or change.

For purposes of the merger agreement and with respect to an Acquisition Proposal, “Superior Proposal” means a written bona fide Acquisition Proposal (except that, for purposes of this definition, the references in the definition of “Acquisition Proposal” to “twenty percent (20%)” shall be replaced by “fifty percent (50%)”) made by a third party on terms that the MAA Board or the Colonial Board, as applicable, determines in its good faith judgment, after consultation with outside legal counsel and financial advisors, taking into account all financial, legal, regulatory and any other aspects of the transaction described in such proposal and such other relevant factors (including, without limitation, the identity of the person making such proposal, any break-up fees, expense reimbursement provisions, conditions to consummation and feasibility and certainty of consummation (including whether consummation is reasonably capable of being completed on a timely basis on the terms proposed), as well as any changes to the financial terms of the merger agreement proposed by the other party in response to such proposal or otherwise), would, if consummated, be more favorable to MAA and its shareholders or Colonial and its shareholders, as applicable, from a financial point of view than the transactions contemplated by the merger agreement.

The merger agreement requires each of MAA and Colonial to, and to cause their respective subsidiaries to, immediately terminate any and all existing activities, discussions or negotiations with any third parties conducted prior to June 3, 2013 with respect to any Acquisition Proposal, and to agree that it will not release any third party from, or waive any provisions of, any confidentiality or standstill agreement to which it or any of its subsidiaries is a party with respect to any Acquisition Proposal. Each of MAA and Colonial further agrees that it will use its reasonable best efforts to promptly inform its and its subsidiaries’ respective representatives of these obligations.

Unless the merger agreement is terminated with respect to a Superior Proposal, notwithstanding a Change in Recommendation, each of Colonial and MAA has agreed to submit the adoption of the merger agreement to a vote of its respective shareholders. In addition, MAA and Colonial have agreed not to submit any Acquisition Proposal other than the mergers to a vote of its respective shareholders prior to the termination of the merger agreement.

Each of MAA and Colonial will hold, and to cause its representatives and affiliates to hold, any non-public information in confidence to the extent required by the terms of its existing confidentiality agreements.

Each of MAA and Colonial will give prompt written notice to the other upon becoming aware of the occurrence or impending occurrence of any event or circumstance relating to it or to any of its subsidiaries which could reasonably be expected to have, individually or in the aggregate, a material adverse effect.

Each of MAA and Colonial will provide prompt notice to the other if any representation or warranty made by it in the merger agreement becomes untrue or inaccurate such that the applicable closing conditions would reasonably be expected to be incapable of being satisfied by December 31, 2013, or if it fails to comply with or satisfy in any material respect any covenant, condition or agreement contained in the merger agreement.

Each of MAA and Colonial will provide prompt notice to the other of any actions, suits, claims, investigations or proceedings commenced or threatened against, relating to or involving such party or any of its subsidiaries in connection with the merger agreement, the mergers or the other transactions contemplated by the merger agreement.

Prior to the effective time of the partnership merger, Colonial will purchase, and MAA will maintain, a “tail” prepaid insurance policy or policies with a claim period for six years from the effective time of the partnership merger for Colonial’s and its subsidiaries’ current and former trustees, directors, officers, agents and fiduciaries for facts or events that occurred at or prior to the effective time of the partnership merger with terms, conditions, coverage and amounts no less favorable than those of Colonial’s existing directors’ and officers’ liability insurance and fiduciary insurance.

If Colonial is unable to obtain a “tail” policy as of the effective time of the partnership merger, MAA must, at Colonial’s request, purchase and maintain in full force and effect, during the six year period following the effective time of the partnership merger, a “tail” insurance policy from one or more insurance carriers believed to be sound and reputable with respect to directors’ and officers’ liability insurance and fiduciary liability insurance, with terms, conditions, coverage and amounts no less favorable than those of Colonial’s existing directors’ and officers’ liability insurance and fiduciary insurance.

You are encouraged to read each of the Forms of Voting Agreement carefully and their entirety. A copy of the Form of Voting Agreement entered into with certain trustees of Colonial is attached as Annex C to this joint proxy statement/prospectus and incorporated herein by reference. A copy of the Form of Voting Agreement entered into with certain directors and shareholders of MAA is attached as Annex D to this joint proxy statement/prospectus and incorporated herein by reference.

Concurrently with the execution of the merger agreement, Colonial and Colonial LP entered into separate Voting Agreements with H. Eric Bolton, Jr., MAA’s Chairman and Chief Executive Officer, W. Reid Sanders, a member of the MAA Board, and another shareholder of MAA who is not a director or officer of MAA, and MAA and MAA LP entered into separate Voting Agreements with Thomas H. Lowder, James K. Lowder and Harold W. Ripps, each members of the Colonial Board. As of July 16, 2013, the MAA directors and shareholders that are a party to a Voting Agreement with Colonial and Colonial LP collectively owned approximately 0.36% of the outstanding shares of MAA common stock and approximately 37.30% of the outstanding limited partnership units in MAA LP, and the Colonial trustees that are a party to a Voting Agreement with MAA and MAA LP collectively owned approximately 3.9% of the outstanding Colonial common shares and approximately 3.5% of the outstanding limited partnership units in Colonial LP (including limited partnership units held by Colonial).

Because the exchange ratio will not be adjusted for changes in the market price of either shares of MAA common stock or Colonial common shares, the market value of the shares of MAA common stock that holders of Colonial common shares will have the right to receive on the date the mergers are completed may vary significantly from the market value of the shares of MAA common stock that holders of Colonial common shares would receive if the mergers were completed on the date of this joint proxy statement/prospectus. As a result, you should obtain recent market prices of shares of MAA common stock and Colonial common shares prior to voting your shares. See “Risk Factors—Risk Factors Relating to the Mergers” beginning on page 32.

172

DISSENTERS’ RIGHTS

As provided in Section 10A-10-1.15 of the AREITL, if the parent merger is consummated, holders of Colonial common shares who follow the procedures specified by Article 13 of the ABCL will be entitled to determination and payment in cash of the “fair value” of their shares (as determined immediately before the effective time of the parent merger), excluding any appreciation or depreciation in value in anticipation of the parent merger, unless such exclusion would be inequitable, but including interest from the effective time of the parent merger until the date of payment.

The following summary of the provisions of Article 13 of the ABCL is not intended to be a complete statement of such provisions (the full text of which is attached as Annex H to this joint proxy statement/prospectus), and is qualified in its entirety by reference thereto.

A holder of Colonial common shares electing to exercise dissenters’ rights (1) must deliver to Colonial at 2101 Sixth Avenue North, Suite 750, Birmingham, Alabama 35203, Attention: Corporate Secretary, before the vote at the Colonial special meeting is taken, written notice of his or her intent to demand payment for his or her shares if the parent merger is effectuated, and (2) must not vote in favor of the parent merger. A vote in favor of the parent merger by a holder of Colonial common shares will result in the waiver of such shareholder’s right to demand payment for his or her shares.

The requirement of written notice to Colonial is in addition to and separate from the requirement that such shares not be voted in favor of the parent merger, and the requirement of written notice is not satisfied by voting against the parent merger either in person or by proxy. The requirement that shares not be voted in favor of the parent merger will be satisfied if no proxy is returned and the shares are not voted in person. Because a properly executed and delivered proxy which is left blank will, unless revoked, be voted “FOR” approval of the parent merger, in order to be assured that his or her shares are not voted in favor of the parent merger, a dissenting shareholder who votes by proxy must not leave the proxy blank but must (1) vote “AGAINST” the approval of the parent merger or (2) affirmatively “ABSTAIN” from voting. Neither a vote against approval of the parent merger nor an abstention will satisfy the requirement that a written notice of intent to demand payment be delivered to Colonial before the vote on the parent merger.

A record shareholder may assert dissenters’ rights as to fewer than all of the shares registered in his or her name only if he or she dissents with respect to all shares beneficially owned by any one person and notifies Colonial in writing of the name and address of each person on whose behalf he or she asserts dissenters’ rights. A beneficial shareholder of Colonial may assert dissenters’ rights as to shares held on his or her behalf only if he or she submits to Colonial the record shareholder’s written consent to the dissent prior to or contemporaneously with such assertion and he or she does so with respect to all shares of which he or she is the beneficial shareholder or over which he or she has the power to vote. Where no number of shares is expressly mentioned, the notice of intent to demand payment will be deemed to cover all shares held in the name of the record holder.

No later than 10 days after the parent merger, the Combined Corporation will send a written dissenters’ notice to each dissenting shareholder who did not vote in favor of the parent merger and who duly filed a written notice of intent to demand payment in accordance with Article 13 of the ABCL. The dissenters’ notice will specify, among other things, the deadline by which time the Combined Corporation must receive a payment demand from the dissenting shareholders and will include a form for demanding payment. The deadline to submit a dissenting shareholder’s payment demand will be no fewer than 30 days and no more than 60 days after the date the dissenters’ notice is delivered. It is the obligation of any dissenting shareholder to initiate all necessary action to perfect his or her dissenters’ rights within the time periods prescribed in Article 13 of the ABCL and the dissenters’ notice. If no payment demand is timely received from a dissenting shareholder in the manner set forth in the dissenters’ notice and under Article 13 of the ABCL, all dissenters’ rights of such dissenting shareholder will be lost, notwithstanding any previously submitted written notice of intent to demand payment.

173

Each dissenting shareholder who timely demands payment will retain all other rights of a shareholder unless and until those rights are cancelled or modified by the parent merger. A dissenting shareholder who demands payment in accordance with the foregoing may not thereafter withdraw that demand and accept the terms offered under the parent merger unless the Combined Corporation consents thereto.

Within 20 days of making a formal payment demand, the dissenting shareholder must submit his or her share certificate or certificates to the Combined Corporation so that a notation indicating that demand has been made may be placed on such certificate or certificates and the certificate or certificates returned to the dissenting shareholder with the notation thereon. A shareholder’s failure to submit his or her certificate or certificates for notation will, at the Combined Corporation’s option, terminate the holder’s rights as a dissenter, unless a court of competent jurisdiction, for good and sufficient cause, directs otherwise.

Promptly after the parent merger, or upon receipt of a payment demand, the Combined Corporation shall offer to pay each dissenting shareholder who complied with Article 13 of the ABCL the amount the Combined Corporation estimates to be the fair value of such dissenting shareholder’s shares plus accrued interest. Each dissenting shareholder who agrees to accept the offer of payment in full satisfaction of his or her demand must surrender to the Combined Corporation the certificate or certificates representing his or her shares in accordance with the terms of the dissenters’ notice. Upon receiving the certificate or certificates, the Combined Corporation will pay each accepting dissenting shareholder the fair value of his or her shares, plus accrued interest. Upon receiving payment, each dissenting shareholder ceases to have any interest in the shares.

Each dissenting shareholder who has made a payment demand may notify the Combined Corporation in writing of his or her own estimate of the fair value of his or her shares and the amount of interest due, and demand payment of his or her estimate, or reject the offer made to such shareholder by the Combined Corporation and demand payment of the fair value of his or her shares and interest due, if: (1) the dissenting shareholder believes that the amount offered by the Combined Corporation is less than the fair value of the shares or that the interest due is calculated incorrectly; (2) the Combined Corporation fails to make an offer as required by Article 13 of the ABCL within 60 days after the date set for demanding payment or (3) the Combined Corporation fails to take the proposed action and to remove the notation on the shareholder’s certificates within 60 days after the date set for demanding payment; provided, however, a dissenting shareholder waives the right to demand payment different from that offered by the Combined Corporation unless he or she notifies the Combined Corporation of his or her demand in writing within 30 days after the Combined Corporation offered payment for his or her shares.

If a demand for payment remains unsettled, the Combined Corporation must commence a proceeding within 60 days after receiving a dissenting shareholder’s payment demand and petition the court to determine the fair value of the shares and accrued interest. If the proceeding is not commenced within the 60 day period, each dissenting shareholder whose demand remains unsettled shall be entitled to receive the amount such dissenting shareholder demanded. Such a proceeding will be filed in the Circuit Court of Montgomery County, Alabama. The Combined Corporation will make all dissenting shareholders whose demands remain unsettled, whether or not residents of Alabama, parties to the proceeding as in an action against their shares, and all parties must be served with a copy of the petition.

Each dissenting shareholder made a party to the proceeding is entitled to judgment for the amount the court finds to be the fair value of his or her shares, plus accrued interest. Upon payment of the judgment and surrender to the Combined Corporation of the certificate or certificates representing the judicially appraised shares, a dissenting shareholder will cease to have any interest in the shares. The court may assess costs incurred in such a proceeding against the Combined Corporation or may assess the costs against all or some of the dissenting shareholders, in amounts the court finds equitable, to the extent the court finds that such dissenting shareholders acted arbitrarily, vexatiously or not in good faith in demanding payment different from that initially offered by the Combined Corporation. The court may also assess the reasonable fees and expenses of counsel and experts against the Combined Corporation if the court finds that it did not substantially comply with its requirements

174

regarding providing notice of dissenters’ rights and the procedures associated therewith under Article 13 of the ABCL or against either the Combined Corporation or all or some of the dissenting shareholders if the court finds that such party against whom the fees and expenses are assessed acted arbitrarily, vexatiously or not in good faith with respect to the rights provided in Article 13 of the ABCL. If the court finds that services of counsel for any dissenting shareholder were of substantial benefit to other similarly situated dissenting shareholders, and that fees for such services should not be assessed against the Combined Corporation, then the court may award reasonable fees to such counsel that will be paid out of the amounts awarded to dissenting shareholders who benefited from such services.

Shareholders considering seeking appraisal should be aware that the fair value of their shares as so determined could be more than, the same as or less than the consideration they would receive pursuant to the parent merger if they did not seek appraisal of their shares and that investment banking opinions as to the fairness, from a financial point of view, of the consideration payable in a sale transaction, such as the parent merger, are not opinions as to, and do not otherwise address, fair value under Article 13 of the ABCL.

MAA shareholders will have no right to dissent from the parent merger or to demand an appraisal of their shares of MAA common stock.

175

DESCRIPTION OF CAPITAL STOCK

The following is a summary of some of the terms of MAA’s capital stock, the MAA charter, as further amended, MAA’s amended and restated bylaws, or the MAA bylaws, and certain provisions of the Tennessee Business Corporation Act, or the TBCA. You should read the MAA charter and the MAA bylaws and the applicable provisions of Tennessee law for complete information on MAA’s capital stock. The following summary is not complete and is subject to, and qualified in its entirety by reference to, the provisions of the MAA charter and bylaws. To obtain copies of these documents, see “Where You Can Find More Information” beginning on page 201.

The description of MAA capital stock in this section applies to the capital stock of the Combined Corporation after the parent merger. For additional information, see “Comparison of Rights of Shareholders of MAA and Shareholders of Colonial” beginning on page 182.

Shares Authorized

MAA’s authorized capital stock consists of 100,000,000 shares of common stock and 20,000,000 shares of preferred stock.

Shares Outstanding

As of [—], 2013, the record date for the MAA special meeting, MAA had [—] shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding. Upon consummation of the parent merger, the Combined Corporation is expected to have approximately [—] shares of common stock issued and outstanding and no shares of preferred stock issued and outstanding.

Common Stock

Holders of shares of MAA common stock are entitled to one vote per share on all matters to be voted on by common shareholders and, subject to any preferential rights granted by the MAA Board to any series of preferred stock, are entitled to receive ratably such dividends as may be declared in respect of the common stock by the MAA Board in its discretion from funds legally available therefor. In the event of MAA’s liquidation, dissolution or winding-up, holders of common stock are entitled to share ratably in all assets remaining after payment of all debts and other liabilities and any liquidation preference payable on MAA’s then-outstanding preferred stock. Holders of MAA common stock have no preference, subscription, redemption, conversion, exchange, sinking fund or preemptive rights. Subject to the voting rights, if any, of any preferred stock outstanding at the time of a shareholder vote, action on a matter submitted for shareholder approval at a shareholders’ meeting (other than the election of directors) is generally approved if the votes cast by the holders of common stock in favor of the action exceed the votes cast opposing the action, while directors are elected by a plurality of the votes cast by the shares entitled to vote in the election. Holders of MAA common stock do not have cumulative voting rights in the election of MAA’s directors. This means that the holders of a majority of the outstanding shares of MAA common stock will generally be entitled, subject to the rights, if any, of any preferred stock outstanding at any time to vote in the election of directors, to elect all of MAA’s directors standing for election. The outstanding shares of MAA common stock are fully paid and nonassessable, and the shares of MAA common stock to be issued in connection with the parent merger will be fully paid and nonassessable.

Shares of MAA common stock are subject to restrictions on ownership and transfer designed to preserve MAA’s qualification as a REIT for U.S. federal income tax purposes. See “—Certain Matters of Corporate Governance—Ownership Limitations” below.

Preferred Stock

Under the MAA charter, the MAA Board is authorized, without shareholder action, to cause the issuance of up to 20,000,000 shares of preferred stock, in such series, and with such preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or other provisions, as may be fixed by the

176

MAA Board. As a result, the MAA Board may afford the holders of any series of preferred stock preferences, powers, and rights, voting or otherwise, that may dilute or otherwise adversely affect the economic, voting and other rights of holders of MAA common stock and may also provide any series of preferred stock with preferences over MAA common stock as to dividends and the distribution of assets in the event of MAA’s liquidation, dissolution or winding-up.

Although no MAA preferred stock is outstanding as of the date of this joint proxy statement/prospectus, MAA has from time-to-time in the past issued series of preferred stock and may do so again in the future. In particular, the MAA Board has previously designated and established the terms of the following series of preferred stock:

•

2,000,000 shares of 9.5% Series A Cumulative Preferred Stock, of which no shares are outstanding;

•

2,156,250 shares of 8.875% Series B Cumulative Preferred Stock, of which no shares are outstanding;

•

2,000,000 shares of 9.375% Series C Cumulative Redeemable Preferred Stock, of which no shares are outstanding;

•

1,000,000 shares of 9.5% Series E Cumulative Redeemable Preferred Stock, of which no shares are outstanding;

•

3,000,000 shares of 9.25% Series F Cumulative Redeemable Preferred Stock, of which no shares are outstanding;

•

400,000 shares of 8.625% Series G Cumulative Redeemable Preferred Stock, of which no shares are outstanding; and

•

6,200,000 shares of 8.30% Series H Cumulative Redeemable Preferred Stock, of which no shares are outstanding.

MAA has redeemed or retired all of the shares of the preferred stock referred to in the foregoing bullet points. However, under Tennessee law, these shares, although no longer outstanding, are still allocated to the respective series referred to above and therefore cannot (absent an appropriate amendment to the MAA charter) be reissued except as a part of such series and with the dividend rate and other terms and provisions of such series previously established by the MAA Board. Accordingly, as of the date of this joint proxy statement/prospectus, of the 20,000,000 shares of preferred stock that MAA is authorized to issue pursuant to the MAA charter, a total of 16,756,250 of those shares have been allocated to the respective series set forth in the bullet points above, leaving 3,243,750 shares of preferred stock that may be issued from time-to-time in such amounts and series and with such terms and provisions as may be established from time-to-time by the MAA Board.

Power to Issue Additional Shares of Common and Preferred Stock

MAA may issue additional shares of common stock or preferred stock and classify and issue additional series of preferred stock. These actions can be taken without action by MAA’s shareholders, unless shareholder approval is required by applicable law or rule of any stock exchange or automated quotation system on which MAA stock may be listed or traded. MAA may issue a class or series of stock that could delay, defer or prevent a transaction or a change in control of MAA that that might involve a premium price for MAA common stock or that the holders of MAA common stock otherwise believe to be in their best interest. MAA’s issuance of additional shares of capital stock in the future could dilute the voting and other rights of shares held by existing shareholders.

Certain Matters of Corporate Governance

Charter and Bylaw Provisions

The TBCA, the MAA charter and the MAA bylaws govern MAA shareholders’ rights and related matters. Certain provisions of the MAA charter and MAA bylaws, which are described below, may make it more difficult to change the composition of the MAA Board and may discourage or make more difficult any attempt by a person or group to obtain control of MAA.

177

Voting Requirement

Under the TBCA, the MAA charter generally may not be amended without shareholder approval. Except as provided below and subject to the voting rights of any preferred stock outstanding at the time of a shareholder vote, any amendment to the MAA charter submitted for shareholder approval at a shareholders’ meeting is generally approved if it receives the affirmative vote of the majority of shares present in person or represented by proxy at the meeting and entitled to vote generally on the subject matter. Additionally, the MAA charter provides that the MAA Board cannot take any action intended to terminate MAA’s qualification as a REIT without the affirmative vote of at least two-thirds of the outstanding shares of common stock. Under the TBCA, MAA’s shareholders may amend the MAA bylaws if the number of votes cast in favor of the amendment exceeds the number of votes cast against the amendment. Additionally, MAA’s directors may amend the MAA bylaws upon the affirmative vote of a majority of the directors then in office, unless the shareholders prescribe that any such bylaw may not be amended or repealed by the MAA Board or unless the TBCA or the MAA charter otherwise provides.

Special Meetings

Under the MAA bylaws, shareholders may require MAA to call special meetings of the shareholders only if such shareholders hold outstanding shares representing more than 10% of all votes entitled to be cast at any such special meeting.

Advance Notice of Director Nominations and New Business

The MAA bylaws provide that with respect to an annual meeting of shareholders, nominations of persons for election to the MAA Board and the proposal of other business to be considered by shareholders may be made only (i) by or at the direction of the MAA Board or (ii) by any MAA shareholder who (A) was a shareholder of record at the time of giving the notice as provided for in the MAA bylaws and at the time of the annual meeting, (B) is entitled to vote at the meeting, and (C) has complied with the advance notice procedures set forth in the MAA bylaws. In addition, with respect to any special meeting of shareholders at which directors are to be elected, nominations of persons for election to the MAA Board may be made only (i) by or at the direction of the MAA Board or (ii) by any MAA shareholder who (A) was a shareholder of record at the time of giving the notice as provided for in the MAA bylaws and at the time of the special meeting, (B) is entitled to vote at the meeting, and (C) has complied with the advance notice procedures set forth in the MAA bylaws.

The advance notice provisions of the MAA bylaws could have the effect of discouraging a takeover or other transaction in which holders of MAA common stock might receive a premium for their shares over the then prevailing market price or which such holders might believe to be otherwise in their best interests.

Limitation of Director’s Liability

The MAA charter eliminates, subject to certain exceptions, the personal liability of a director to MAA or its shareholders for monetary damages for breaches of such director’s fiduciary duty as a director. The MAA charter does not provide for the elimination of or any limitation on the personal liability of a director for:

•

any breach of a director’s duty of loyalty to MAA or its shareholders;

•

acts or omissions not in good faith or which involve intentional misconduct or knowing violations of law; or

•

unlawful corporate distributions.

Removal of Directors

The MAA bylaws provide that MAA shareholders may remove any director, with or without cause, but such removal requires the affirmative vote of holders of not less than 75% of all shares entitled to vote in the election of directors at a special meeting called for that purpose. This provision may make it more difficult for shareholders to remove directors.

178

Tennessee Anti-Takeover Statutes

In addition to certain of the MAA charter and MAA bylaws provisions discussed above and below, Tennessee has adopted a series of statutes which can have an anti-takeover effect and may delay or prevent a tender offer or takeover attempt that a shareholder might consider in its best interest, including those attempts that might result in a premium over the market price for MAA common stock.

Under the Tennessee Investor Protection Act, unless the MAA Board has recommended a takeover offer to shareholders, no offeror beneficially owning five percent or more of any class of equity securities of MAA, any of which was purchased within one year prior to the proposed takeover offer (unless the offeror, before making such purchase, has made a public announcement of its intention with respect to changing or influencing the management or control of MAA, has made a full, fair and effective disclosure of such intention to the person from whom the offeror intends to acquire such securities and has filed with the Tennessee Commissioner of Commerce and Insurance, or the “Commissioner,” and MAA a statement signifying such intentions and containing such additional information as the Commissioner by rule prescribes), may offer to acquire any class of equity security of MAA pursuant to a tender offer if after the acquisition thereof the offeror would be directly or indirectly a beneficial owner of more than 10% of any class of outstanding equity securities of the offeree company, or a Takeover Offer. Such an offeror must provide that any equity securities of MAA deposited or tendered pursuant to a Takeover Offer may be withdrawn by an offeree at any time within seven days from the date the offer has become effective following filing with the Commissioner and MAA and public announcement of the terms or after 60 days from the date the offer has become effective. If an offeror makes a Takeover Offer for less than all the outstanding equity securities of any class, and if the number of securities tendered is greater than the number the offeror has offered to accept and pay for, the securities shall be accepted pro rata. If an offeror varies the terms of a Takeover Offer before its expiration date by increasing the consideration offered to offeree, the offeror shall pay the increased consideration for all equity securities accepted, whether accepted before or after the variation in the terms of the offer.

Under the Tennessee Business Combination Act, subject to certain exceptions, MAA may not engage in any “business combination” with an “interested shareholder” for a period of five years following the date that such shareholder became an interested shareholder unless prior to such date the MAA Board approved either the business combination or the transaction which resulted in the shareholder becoming an interested shareholder.

A “business combination” is defined by the Tennessee Business Combination Act as any:

•

merger or consolidation;

•

share exchange;

•

sale, lease, exchange, mortgage, pledge or other transfer of assets representing 10% or more of:

•

the aggregate market value of the corporation’s consolidated assets;

•

the aggregate market value of the corporation’s shares; or

•

the corporation’s consolidated net income;

•

issuance or transfer of shares by the corporation to the interested shareholder;

•

plan of liquidation or dissolution proposed by the interested shareholder;

•

transaction or recapitalization which increases the proportionate share of any outstanding voting securities owned or controlled by the interested shareholder; or

•

financing arrangement whereby any interested shareholder receives, directly or indirectly, a benefit except proportionately as a shareholder.

179

An “interested shareholder” is defined as:

•

any person that is the beneficial owner of 10% or more of the voting power of any class or series of outstanding voting stock of the corporation; or

•

an affiliate or associate of the corporation who at any time within the five-year period immediately prior to the date in question was the beneficial owner, directly or indirectly, of 10% or more of the voting power of any class or series of the outstanding stock of the corporation.

Consummation of a business combination that is subject to the five-year moratorium is permitted after such period when the transaction complies with all applicable charter and bylaw requirements and either (i) is approved by the holders of two-thirds of the voting stock not beneficially owned by the interested shareholder, or (ii) meets certain fair price criteria.

The Tennessee Greenmail Act prohibits MAA from purchasing, directly or indirectly, any of its shares at a price above the market value of such shares (defined as the average of the highest and lowest closing market price for such shares during the 30 trading days preceding the purchase and sale or preceding the commencement of a tender offer or announcement of an intention to seek control of the corporation if the seller of such shares has commenced a tender offer or announced an intention to seek control of the corporation) from any person who holds more than three percent of the class of securities to be purchased if such person has held such shares for less than two years, unless the purchase has been approved by the affirmative vote of a majority of the outstanding shares of each class of voting stock issued by such corporation or the corporation makes an offer, of at least equal value per share, to all holders of shares of such class.

Ownership Limitations

For MAA to qualify as a REIT under the Code, among other things, no more than 50% in value of MAA’s outstanding shares of capital stock may be owned, directly or indirectly, by five or fewer shareholders (as defined in the Code to include certain entities) during the last half of a taxable year, and such capital stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months or during a proportionate part of a shorter taxable year. To ensure that MAA continues to meet the requirements for qualification as a REIT, the MAA charter provides, subject to certain limited exceptions, that no holder may own, or be deemed to own by virtue of the attribution provisions of the Code, more than 9.9% of the outstanding shares of MAA’s capital stock, both common and preferred, which is referred to as the Ownership Limit. All shares of MAA’s capital stock which any person has the right to acquire upon exercise of outstanding rights, options or warrants, or upon conversion of convertible securities, shall be considered for purposes of determining the Ownership Limit if inclusion of those shares would cause such person to violate the Ownership Limit. The MAA Board may exempt from the Ownership Limit ownership or transfer of shares of capital stock while owned by or transferred to a person who has provided evidence and assurances acceptable to the MAA Board that MAA’s qualification as a REIT under the Code would not be jeopardized thereby. Absent such an exemption, any transfer of capital stock that would result in direct or indirect ownership of capital stock by a shareholder in excess of the Ownership Limit or that would result in MAA’s disqualification as a REIT under the Code, including any transfer that results in the capital stock being owned by fewer than 100 persons or results in MAA being “closely held” within the meaning of section 856(h) of the Code, shall be null and void, and the intended transferee will acquire no rights to the capital stock. If the MAA Board at any time determines that a transaction has taken place, or that any person intends to acquire shares of MAA’s capital stock, in violation of the restrictions described in the immediately preceding sentence, the MAA Board may take such action as it deems advisable to refuse to give effect to or to prevent such transaction, including refusing to give effect to any such transfer on MAA’s stock transfer books.

If, notwithstanding the foregoing restrictions on transfer, any person acquires shares in excess of the Ownership Limit, such shares shall be deemed “Excess Shares” held by such holder as agent on behalf of, and in trust for the exclusive benefit of, the transferees (which may include MAA) to whom such capital stock may be ultimately transferred without violating the Ownership Limit. While the Excess Shares are held in trust, the holder thereof will not be entitled to vote the Excess Shares or to receive dividends or other distributions on the Excess Shares.

180

Within six months after receiving notice of a transfer that results in shares of MAA’s capital stock being deemed Excess Shares, the MAA Board shall either direct the holder to sell the Excess Shares or shall redeem the Excess Shares. If the MAA Board directs a holder of Excess Shares to sell such Excess Shares, such holder shall pay MAA out of the proceeds of such sale all expenses incurred by MAA in connection with such sale plus any remaining amount of such proceeds that exceeds that amount paid by such holder for the Excess Shares.

If the MAA Board determines to redeem the Excess Shares, the MAA Board will notify the holder of Excess Shares not less than one week prior to the redemption date determined by the MAA Board and stated in the notice of redemption. MAA will pay the holder a redemption price equal to the lesser of (a) the principal price paid for the Excess Shares by the holder, (b) a price per Excess Share equal to the market price (as determined in the manner set forth in MAA’s charter) of the applicable capital stock, (c) the market price (as so determined) on the date such holder would, but for the restrictions on transfers set forth in MAA’s charter, be deemed to have acquired ownership of the Excess Shares (if market price is not determinable (as set forth in MAA’s charter), the net asset value per share on the date of the notice of redemption as determined in good faith by the MAA Board). and (d) the maximum price allowed under the Tennessee Greenmail Act described above under “—Tennessee Anti-Takeover Statutes” (such price being the average of the highest and lowest closing market price for the Excess Shares during the 30 trading days preceding the purchase of such Excess Shares or, if the holder of such Excess Shares has commenced a tender offer or has announced an intention to seek control of MAA, during the 30 trading days preceding the commencement of such tender offer or the making of such announcement). The redemption price may be paid, at MAA’s option, by delivering to the holder of the Excess Shares one common unit (subject to adjustment from time-to-time in the event of, among other things, stock splits, stock dividends or recapitalizations affecting MAA common stock or certain mergers, consolidations or asset transfers by MAA) issued by MAA LP for each Excess Share being redeemed.

Each shareholder shall upon demand be required to provide MAA with an affidavit setting forth any information with respect to its direct, indirect, constructive and beneficial ownership of MAA’s capital stock as the MAA Board deems necessary to comply with the provisions of the Code applicable to REITs or to determine any such compliance. Each such affidavit shall also include the information required to be filed by shareholders in reports pursuant to Section 13(d) of the Exchange Act. A person planning to acquire capital stock in excess of the Ownership Limit is also required to provide MAA with a similar affidavit at least 15 days prior to the proposed acquisition.

The Ownership Limit may have the effect of precluding acquisition of control of MAA and could have the effect of discouraging a takeover or other transaction in which holders of common stock might receive a premium for their shares over the then prevailing market price or which such holders might believe to be otherwise in their best interests.

Other Matters

Pursuant to the TBCA, MAA cannot merge with and into another entity or sell all or substantially all of its assets unless such merger or sale is approved by a majority of the outstanding shares of MAA common stock.

Transfer Agent

The transfer agent and registrar for shares of MAA common and preferred stock is American Stock Transfer & Trust Company, Brooklyn, New York.

COMPARISON OF RIGHTS OF SHAREHOLDERS OF MAA AND SHAREHOLDERS OF COLONIAL

If the parent merger is consummated, shareholders of Colonial will become shareholders of MAA. The rights of Colonial shareholders are currently governed by and subject to the provisions of the AREITL, and the declaration of trust and bylaws of Colonial. Upon consummation of the parent merger, the rights of the former Colonial shareholders who receive MAA common stock will be governed by the TBCA and the MAA charter and MAA bylaws, rather than the declaration of trust and bylaws of Colonial.

The following is a summary of the material differences between the rights of MAA shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger) and Colonial shareholders, but does not purport to be a complete description of those differences or a complete description of the terms of the MAA common stock subject to issuance in connection with the parent merger. The following summary is qualified in its entirety by reference to the relevant provisions of: (i) Tennessee law; (ii) Alabama law; (iii) the MAA charter; (iv) the Colonial declaration of trust; (v) the MAA bylaws; and (vi) the Colonial bylaws.

This section does not include a complete description of all differences among the rights of MAA shareholders and Colonial shareholders, nor does it include a complete description of the specific rights of such shareholders. The AREITL covers some of the same matters covered by the ABCL. However, there are some corporate governance matters that are addressed in the ABCL that are not dealt with in the AREITL. Colonial has addressed particular corporate governance matters in the Colonial declaration of trust and bylaws. For corporate governance matters not addressed in the AREITL or in the Colonial declaration of trust and bylaws, Colonial believes that the treatment of such matters in the ABCL may be a relevant consideration in determining applicable Alabama law.

Furthermore, the identification of some of the differences in the rights of such holders as material is not intended to indicate that other differences that may be equally important do not exist. You are urged to read carefully the relevant provisions of Tennessee and Alabama law, as well as the governing corporate instruments of each of MAA and Colonial, copies of which are available, without charge, to any person, including any beneficial owner to whom this joint proxy statement/prospectus is delivered, by following the instructions listed under “Where You Can Find More Information.”

	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders

		At June 30, 2013, there were issued and outstanding 88,744,357 Colonial common shares. There are no Colonial preferred shares or excess shares outstanding.

	Preferred Stock. The MAA Board is authorized to issue preferred stock from time-to-time in such series and with such preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications, or other provisions as may be fixed by the MAA Board.	Preferred Shares. The Colonial Board, pursuant to the declaration of trust but subject to any shareholder approval required by the Alabama Constitution, may authorize the issuance of one or more series of Colonial preferred shares, fixing the numbers, designations, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications and terms or conditions of redemption. The Colonial Board may also issue other securities of Colonial, having voting rights, dividend or interest rates, preferences, subordinations, conversion or redemption prices or rights, maturity dates, distribution, exchange or liquidation rights or other rights as the trustees may determine, without shareholder vote except as may be required by the Alabama Constitution.

Voting Rights	Each shareholder of MAA common stock is entitled to one vote per share on all matters upon which shareholders are entitled to vote. Unless a greater vote is otherwise required or permitted under the TBCA of the MAA charter, the votes cast favoring the action exceed the votes cast opposing the action shall be the act of the shareholders, except with respect to the election of directors, who are elected based on the candidates receiving the highest number of votes at a meeting.	Each holder of Colonial common shares is entitled to one vote per share on all matters upon which shareholders are entitled to vote under the Colonial declaration of trust. Unless a greater vote is otherwise required by the Alabama Constitution, statute or the Colonial declaration of trust, a majority of the votes cast at a meeting at which at least a majority of all votes entitled to be cast are present in person or by proxy is required to approve matters before the shareholders, except with respect to the election of trustees, who are elected based on the candidates receiving the highest number of votes at a meeting. Each share may be voted for as many individuals as there are trustees to be elected and for whose election the share is entitled to be voted. The Colonial declaration of trust provides that, subject to the provisions of any class or series of shares then outstanding and to mandatory provisions of law, the Colonial shareholders will be entitled to vote only on the following matters: • an increase or decrease in the number of trustees;

183


	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders

		• election or removal of trustees of Colonial; • amendment of the Colonial declaration of trust; • termination of the existence of Colonial; • reorganization of Colonial; • merger, consolidation or sale or other disposition of all or substantially all of Colonial’s property; and • termination of Colonial’s status as a REIT for U.S. federal tax purposes. Except with respect to the foregoing matters, no action taken by the Colonial shareholders at any meeting will in any way bind the Colonial trustees.

Cumulative Voting	Holders of MAA stock do not have the right to cumulate their votes with respect to the election of directors.	Holders of Colonial shares do not have the right to cumulate their votes with respect to the election of trustees.

Size of the Board of Directors and Board of Trustees	The number of directors must be between three and nine unless otherwise determined by at least 80% of the members of the MAA Board. The number of directors may be established or changed by at least 80% of the members of the MAA Board. Currently, the MAA Board consists of 7 directors. Upon completion of the parent merger, by resolution unanimously adopted by the MAA Board, the board of directors of the Combined Corporation will be increased to 12 directors.	The Colonial declaration of trust provides for a minimum of three and a maximum of 15 trustees, with the number of trustees within this range established by resolution of the Colonial Board, as provided in the Colonial declaration of trust and bylaws. The current size of the Colonial Board is ten.

Independent Directors and Trustees	A majority of the directors on the MAA Board must be independent directors except during a period of up to 60 days following the death, resignation, incapacity or removal of a director.	A majority of the trustees on the Colonial Board must be “independent” in accordance with New York Stock Exchange listing standards.

Classified Board and Term of Directors and Trustees	The MAA Board is not classified. The directors of MAA hold office for a term expiring at the next succeeding annual meeting of shareholders and until their successors are duly elected and qualified.	The Colonial Board is not classified. The trustees of Colonial hold office for a term expiring at the next succeeding annual meeting of shareholders and until their successors are duly elected and qualified.

184


	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders
Election of Directors and Trustees	A plurality of the votes cast by share entitled to vote at the election at a meeting at which a quorum is present shall be sufficient to elect a director.	A plurality of all the votes cast at a meeting of the shareholders duly called and at which a quorum is present shall be sufficient to elect a trustee.

Removal of Directors and Trustees	The TBCA provides that shareholders may remove directors with or without cause unless the charter provides that directors may be removed only for cause. However, if a director is elected by a particular voting group, that director may only be removed by the requisite vote of that voting group. MAA’s bylaws provide that directors may be removed with or without cause by the affirmative vote of holders of 75% of all shares entitled to vote on the election of directors at a special meeting called for that purpose.	Unless the declaration of trust provides otherwise, the AREITL provides that the shareholders of an Alabama real estate investment trust may remove any trustee with or without cause by the affirmative vote of a majority of all of the votes entitled to be cast for the election of trustees. Pursuant to the Colonial declaration of trust, a trustee may be removed, with or without cause, only at a meeting of shareholders called for that purpose, by a vote of not less than two-thirds of the shares then outstanding and entitled to vote in the election of trustees.

Filling Vacancies of Directors and Trustees	The TBCA provides that vacancies on the board of directors, including a vacancy resulting from an increase in the number of directors or a vacancy resulting from a removal with or without cause may be filled by the shareholders, board of directors or, if the remaining directors constitute fewer than a quorum of the board, the affirmative vote of a majority of all the directors remaining in office. If the vacant office was held by a director elected by a voting group of shareholders, then only the holders of shares of that voting group are entitled to vote to fill the vacancy if it is filled by the shareholders. MAA’s bylaws provide that any vacancies on the MAA Board may be filled by a majority of the remaining directors, even though such majority is less than a quorum; provided, however, that vacancies shall be filled in accordance with MAA’s corporate governance guidelines. MAA’s bylaws also provide that any vacancies on the MAA Board resulting from removal of a director by the shareholders may be filled by the shareholders for the balance of the term of the removed director, subject to the independence requirement.	Under the Colonial bylaws, a majority of the trustees shall fill any vacancy, including a vacancy created by an increase in the number of trustees, at any regular meeting or at any special meeting called for that purpose. A trustee chosen by the other trustees to fill a vacancy will serve for the unexpired term of the trustee he is replacing.

185


	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders
Amendment of the MAA Charter and the Colonial Declaration of Trust	The TBCA provides that certain relatively technical amendments to a corporation’s charter may be adopted by the board of directors without shareholder approval. Other amendments to the charter shall be approved, subject to any condition the board of directors may place on its submission of the amendment to the shareholders, if the votes cast favoring the action exceed the votes cast opposing the action, unless the charter, board of directors or applicable law requires a greater vote. Where permissible under the TBCA, including amendments to the MAA charter, the MAA Board has adopted a greater voting standard, requiring the affirmative vote of a majority of shares present in person or represented by proxy at a meeting and entitled to vote generally on the subject matter.	The Colonial declaration of trust provides that, subject to Section 6.3 thereof, the declaration of trust may be amended by: (1) adoption of the amendment by the trustees and submission to the shareholders; and (2) the affirmative vote of the holders of not less than a majority of shares then outstanding and entitled to vote; except that certain provisions relating to the resignation, removal or death of a trustee, the termination of Colonial and amendment to the Colonial declaration of trust require the affirmative vote of the holders of two-thirds of the shares then outstanding and entitled to vote. Notwithstanding, Section 234 of the Alabama Constitution requires the consent of persons holding the larger amount in value of stock to increase the stock of a corporation. Section 237 of the Alabama Constitution provides that no corporation may issue preferred stock without the consent of owners of two-thirds of the stock of the corporation. Further, no amendment to the Colonial declaration of trust or repeal of any of its provisions will limit or eliminate the right of indemnification provided with respect to an act or omission that took place prior to the amendment or repeal.

Bylaw Amendments	Under the TBCA, shareholder action is generally not necessary to amend the bylaws, unless the charter provides otherwise or the shareholders in amending or repealing a particular bylaw provide expressly that the board of directors may not amend or repeal that bylaw. Shareholders may amend or repeal a corporation’s bylaws even though the bylaws may also be amended or repealed by the MAA Board. The MAA bylaws may be amended or repealed and new bylaws may be adopted by (1) a majority vote of the MAA directors then in office or (2) the affirmative vote of the holders of at least a majority of the voting power of all of then-outstanding shares of the capital stock entitled to vote generally in the election of directors, voting together as a single class.	Colonial’s bylaws provide that they may be amended or repealed by either: (1) the affirmative vote of a majority of all shares outstanding and entitled to vote generally in the election of trustees, voting as a single group; or (2) an affirmative vote of a majority of the Colonial Board, unless the shareholders prescribe that any such bylaw may not be amended or repealed by the Colonial Board.

186


	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders

	Any amendments relating to the indemnification provisions set forth in MAA’s bylaws will not adversely affect the right to indemnification or advancement of expenses granted to any person with respect to any act or omission occurring prior to such amendment.	Any amendments relating to the indemnification provisions set forth in Colonial’s bylaws will not affect such bylaw provisions’ applicability with respect to an act or failure to act which occurred prior to the date of such amendment.

Mergers, Consolidations or Sales of Substantially all Assets	Under the TBCA, with respect to a sale or other disposition of all or substantially all of MAA’s assets, a merger of MAA with and into another corporation, or a share exchange involving one or more classes or series of MAA’s shares or a dissolution of MAA, the respective sale or other transaction, plan of merger, the share exchange or dissolution must be approved by the board of directors (except in certain limited circumstances) and, with certain exceptions, by a majority of all the votes entitled to be cast on the applicable proposal, unless a greater vote is required by MAA’s charter, the board of directors or applicable law.	The AREITL provides that a merger shall be approved by the shareholders of a trust by the affirmative vote of two-thirds of all the votes entitled to be cast on the merger. However, notwithstanding any provision of the AREITL which requires for any action the concurrence of a greater proportion of the votes than a majority of the votes entitled to be cast, a trust may provide by its declaration of trust that the action may be taken or authorized on the concurrence of a smaller proportion, but not less than a majority of the number of votes entitled to be cast on the matter. The Colonial declaration of trust provides that, subject to the provisions of any class or series of shares at the time outstanding, the Colonial Board has the power to: (1) merge Colonial into another entity; (2) consolidate Colonial with one or more other entities into a new entity; or (3) sell or otherwise dispose of all or substantially all of Colonial’s property; provided, however, that such action shall have been approved by the affirmative vote of the holders of not less than a majority of the shares then outstanding and entitled to vote on the matter, at a meeting of the shareholders called for that purpose. Pursuant to the partnership agreement of Colonial LP, Colonial, as general partner, will not engage in any merger, consolidation or other combination with or into another person or sale of all or substantially all of its assets, or any reclassification, or recapitalization or change of outstanding Colonial common shares unless: (1) the transaction also includes a merger of Colonial LP or sale of substantially all of assets of Colonial LP which has been approved by three-fourths of the outstanding

		common units held by the limited partners (including common units held by Colonial as limited partnership interests) and as a result of which all limited partners will receive consideration for each common unit based on a specified formula; and (2) no more than 49% of the equity securities of the acquiring person in such transaction will be owned, after consummation of such transaction, by Colonial or persons who are affiliates of Colonial LP or Colonial immediately prior to the date on which the transaction is consummated. Notwithstanding, Colonial may merge with another entity if immediately after such merger substantially all of the assets of the surviving entity, other than partnership units held by Colonial, are contributed to the partnership as a capital contribution in exchange for partnership units with a fair market value, as reasonably determined by Colonial, equal to the value of the assets so contributed determined under Section 704(c) of the Code.

Ownership Limitations	With certain limited exceptions, no person shall beneficially own, or be deemed to own by virtue of the attribution provisions of the Code, more than 9.9% of the outstanding shares of MAA’s capital stock. Upon demand, all shareholders are required to provide written information relating to maintenance of MAA’s REIT status.	With certain limited exceptions, no person shall beneficially own, or be deemed to own by virtue of the attribution provisions of the Code, more than: (1) 9.8%, in either number of shares or value (whichever is more restrictive), of any class of outstanding shares of Colonial; (2) 5% in number or value (whichever is more restrictive) of the outstanding Colonial common shares and the outstanding excess shares of Colonial; and (3) in the case of certain excluded holders related to the Lowder family: (i) 29% by one individual; (ii) 34% by two individuals; (iii) 39% by three individuals; or (iv) 44% by four individuals.

	excess of the ownership limitation are deemed “excess shares.” Excess shares are deemed to be held in trust by the purported transferee for the benefit of the person or persons to whom the board of directors requires the shares to be transferred. The purported transferee has no right to receive dividends or other distributions on or vote the excess shares. The MAA Board may require the purported transferee to sell the excess shares for cash, or may determine to redeem the excess shares, in cash or for partnership units in MAA LP. The MAA Board may exempt from the Ownership Limit ownership or transfer of shares of capital stock while owned by or transferred to a person who has provided evidence and assurances acceptable to the MAA Board that MAA’s qualification as a REIT under the Code would not be jeopardized thereby.	excess of the ownership limitations automatically are exchanged for an equal number of “excess shares.” Any purported transferee or other purported holder of excess shares is required to give written notice to Colonial of a purported transfer or other event that would result in the issuance of excess shares. Excess shares continue as issued and outstanding shares, but are not considered issued and outstanding for purposes of any shareholder vote. Although outstanding, excess shares are to be held in trust, with the trustee of that trust being Colonial. The beneficiary of the trust is to be designated by Colonial. Excess shares participate ratably in any liquidation, dissolution or winding up of Colonial. Excess shares are not entitled to vote on any matter and are not entitled to any dividends or distributions. These ownership limitations may be waived by the Colonial Board if it receives representations and undertakings of certain facts for the protection of Colonial’s REIT status and, if requested, an IRS ruling or opinion of counsel. Absent a waiver, an issuance or transfer of shares in violation of the ownership limitations is void ab initio as to the transfer of such shares that would cause the violation of the ownership limitation and the intended transferee acquires no rights to the shares.

Annual Meetings of the Shareholders	An annual meeting of MAA shareholders shall be held at a time and place as fixed by MAA’s president or the MAA Board, but if no date and time is fixed, than on the first Thursday in May, at 10:00 a.m.	The annual meeting of the shareholders of Colonial shall be held during the second calendar quarter of each year on a date and time set by the Colonial Board.

Special Meetings of the Shareholders	Under the TBCA, the board of directors, any person authorized by the charter or bylaws, or (unless the charter provides otherwise) the holders of at least 10% of the votes entitled to be cast may call a special meeting of shareholders. MAA’s bylaws provide that a special meeting of shareholders may be called at any time by the president, a majority of the board of directors, or a majority of the independent directors.	A special meeting of Colonial’s shareholders may be called by Colonial’s president or chairman of the Colonial Board, or, upon the written request of the holders of shares representing at least 25% of all the votes entitled to be cast on any issue proposed to be considered at any such special meeting of shareholders.

189


	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders
	A special meeting will also be called by the secretary upon the written request of MAA shareholders representing more than 10% of the votes entitled to be cast at such meeting.

	Business transacted at the special meeting of shareholders will be limited to the purposes specifically designated in the notice.	Business transacted at the special meeting of shareholders will be limited to the purposes specifically designated in the notice.

Advance Notice Provisions for Shareholder Nominations and Shareholder Business Proposals	The MAA bylaws provide that nominations for election to the MAA Board and the proposal of business to be considered by the shareholders may be made only: • by or at the direction of the MAA Board; or • upon timely and proper notice by a shareholder who is a shareholder of record at the time of giving of notice and entitled to vote at the meeting. In general, notice of shareholder nominations or business for an annual meeting must be delivered not earlier than 120 days nor later than 90 days prior to the first anniversary of the preceding year’s annual meeting, unless the annual meeting is advanced more than 30 days or delayed more than 60 days from the anniversary date, in which case notice must be delivered not earlier than the 120th day nor later than the 90th day prior to the annual meeting, or, if the first public announcement of the date of such annual meeting is less than 100 days prior to the date of such annual meeting, the tenth day following the day on which the public announcement of the date of the meeting is first made. Notice of shareholder nominations for a special meeting must be delivered not earlier than the 120th day prior to the special meeting, and not later than the close of business on the 90th day prior to the meeting, or, if the first public announcement of the date of such special meeting is less than 100 days prior to the date of such special meeting, the tenth day following the day on which the public announcement is first made of the date of the meeting and the nominees proposed by the MAA Board.	The Colonial bylaws provide that nominations for election to the Colonial Board and the proposal of business to be considered by the shareholders may be made only: • by or at the direction of the Colonial Board; or • upon timely and proper notice by a shareholder who is a shareholder of record at the time of giving of notice and entitled to vote at the meeting. In general, notice of shareholder nominations or business for an annual meeting must be delivered not less than 60 days nor more than 90 days prior to the first anniversary of the preceding year’s annual meeting, unless the annual meeting is advanced more than 30 days or delayed more than 60 days from the anniversary date, in which case notice must be delivered not earlier than the 90th day nor later than the 60th day prior to the annual meeting, or the tenth day following the day on which the public announcement of the date of the meeting is first made.

	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders
Notice of Shareholder Meetings	Not less than 10 days nor more than 2 months before each meeting of shareholders, the secretary shall give notice of such meeting to each shareholder entitled to notice. A shareholder-requested special meeting shall be held not less than 35 days nor more than 120 days after the date of receipt of a shareholder-requested special meeting request.	The Colonial bylaws provide that not less than 10 nor more than 75 days before each meeting of shareholders, Colonial or other persons calling the meeting shall give notice to each shareholder entitled to vote at such meeting, and to each shareholder not entitled to vote but who is entitled to notice of the meeting, written or printed notice stating the date, time and place of the meeting, and in the case of a special meeting or as otherwise may be required by Alabama law, the purpose for which the meeting is called. The notice shall be given either by mail or by presenting it to such shareholder personally or by leaving it at his residence or usual place of business.

State Anti-Takeover Statutes	The Tennessee Control Share Acquisition Act generally provides that, except as stated below, “control shares” will not have any voting rights. Control shares are shares acquired by a person under certain circumstances which, when added to other shares owned, would give such person effective control over one-fifth or more, or a majority of all voting power (to the extent such acquired shares cause such person to exceed one-fifth or one-third of all voting power) in the election of a Tennessee corporation’s directors. However, voting rights will be restored to control shares by resolution approved by the affirmative vote of the holders of a majority of the corporation’s voting stock, other than shares held by the owner of the control shares. If voting rights are granted to control shares which give the holder a majority of all voting power in the election of the corporation’s directors, then the corporation’s other shareholders may require the corporation to redeem their shares at fair value. The Tennessee Control Share Acquisition Act is not applicable to MAA because MAA’s charter does not contain a specific provision “opting in” to the Tennessee Control Share Acquisition Act.	The AREITL does not have any anti-takeover provisions. Further, the Alabama Business Corporation Law, or ABCL, does not contain anti-takeover provisions.

		Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)		Rights of Colonial Shareholders

		The Tennessee Investor Protection Act, or TIPA, provides that unless a Tennessee corporation’s board of directors has recommended a takeover offer to shareholders, no offeror beneficially owning 5% or more of any class of equity securities of the offeree company, any of which was purchased within the preceding year, may make a takeover offer for any class of equity security of the offeree company if after completion the offeror would be a beneficial owner of more than 10% of any class of outstanding equity securities of the company unless the offeror, before making such purchase: (i) makes a public announcement of his or her intention with respect to changing or influencing the management or control of the offeree company; (ii) makes a full, fair and effective disclosure of such intention to the person from whom he or she intends to acquire such securities; and (iii) files with the Tennessee Commissioner of Commerce and Insurance, or the Commissioner, and the offeree company a statement signifying such intentions and containing such additional information as the Commissioner prescribes. The offeror must provide that any equity securities of an offeree company deposited or tendered pursuant to a takeover offer may be withdrawn by an offeree at any time within 7 days from the date the offer has become effective following filing with the Commissioner and the offeree company and public announcement of the terms or after 60 days from the date the offer has become effective. If the takeover offer is for less than all the outstanding equity securities of any class, such an offer must also provide for acceptance of securities pro rata if the number of securities tendered is greater than the number the offeror has offered to accept and pay for. If such an offeror varies the terms of the takeover offer before its expiration date by increasing the consideration offered to offerees, the offeror must pay the increased consideration for all equity securities accepted, whether accepted before or after the variation in the terms of the offer.

192


		Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)		Rights of Colonial Shareholders

		The TIPA does not apply to any offer involving a vote by holders of equity securities of the offeree company. The Tennessee Business Combination Act generally prohibits a “business combination” by MAA or a subsidiary with an “interested shareholder” within 5 years after the shareholder becomes an interested shareholder. MAA or a subsidiary can, however, enter into a business combination within that period if, before the interested shareholder became such, the MAA Board approved the business combination or the transaction in which the interested shareholder became an interested shareholder. After that 5-year moratorium, the business combination with the interested shareholder can be consummated only if it satisfies certain fair price criteria or is approved by 2/3 of the other shareholders. For purposes of the Tennessee Business Combination Act, a “business combination” includes mergers, share exchanges, sales and leases of assets, issuances of securities, and similar transactions. An “interested shareholder” is generally any person or entity that beneficially owns 10% or more of the voting power of any outstanding class or series of MAA stock. The Tennessee Greenmail Act applies to a Tennessee corporation that has a class of voting stock registered or traded on a national securities exchange or registered with the SEC pursuant to Section 12(g) of the Exchange Act. Under the Tennessee Greenmail Act, MAA may not purchase any of its shares at a price above the market value of such shares from any person who holds more than 3% of the class of securities to be purchased if such person has held such shares for less than 2 years, unless the purchase has been approved by the affirmative vote of a majority of the outstanding shares of each class of voting stock issued by MAA or MAA makes an offer, of at least equal value per share, to all shareholders of such class.

193


	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders
Consideration of Other Constituencies	The Tennessee Business Combination Act provides that no corporation (nor its officers or directors) registered or traded on a national securities exchange or registered with the SEC shall be held liable for either having failed to approve the acquisition of shares by an interested shareholder on or before such interested shareholder’s share acquisition date, or for opposing any proposed merger, exchange, tender offer or significant disposition of the assets of the corporation or any of its subsidiaries because of a good faith belief that such merger, exchange, tender offer or significant disposition of assets would adversely affect the corporation’s employees, customers, suppliers, the communities in which such corporation or its subsidiaries operate or are located or any other relevant factor if such factors are permitted to be considered by the board of directors under the charter for such corporation in connection with a merger, exchange, tender offer or significant disposition of assets. MAA’s charter does not contain an “opt-out” provision, and therefore, the Tennessee Business Combination Act will apply.	The AREITL does not address the consideration of other constituencies. The Colonial declaration of trust provides that in determining what is in the best interest of Colonial, a trustee will consider the interests of Colonial shareholders and applicable legal requirements, and in his or her sole discretion, may consider: (1) the interests of Colonial’s employees, suppliers, creditors and customers; (2) the economy of the nation; (3) community and societal interests; and (4) the long-term as well as short-term interests of Colonial and Colonial shareholders, including the possibility that these interests may be best served by Colonial’s continued independence.

Shareholder Rights Plan	MAA does not have a shareholder rights plan in effect.	Colonial does not have a shareholder rights plan in effect.

Liability and Indemnification of Directors, Trustees and Officers	Under the TBCA, MAA may indemnify any director against liability incurred in connection with a proceeding if (i) the director acted in good faith, (ii) the director reasonably believed, in the case of conduct in his or her official capacity, that such conduct was in MAA’s best interest, or, in all other cases, that his or her conduct was not opposed to the best interests of MAA and (iii) in connection with any criminal proceeding, the director had no reasonable cause to believe that his or her conduct was unlawful. In actions brought by or in the right of MAA, however, the TBCA provides that no indemnification may be made if the director or officer is adjudged to be liable to MAA. Similarly, the TBCA prohibits indemnification in connection with any	Under the AREITL, an Alabama real estate investment trust is permitted to expand or limit, by provision in its declaration of trust, the liability of trustees and officers to the trust and its shareholders for money damages except for liability resulting from: (1) actual receipt of an improper benefit or profit in money, property or services; or (2) acts or omissions established by a final judgment as involving active and deliberate dishonesty and being material to the matter giving rise to the proceeding. Colonial’s declaration of trust includes such a provision eliminating such liability to the maximum extent permitted by the AREITL. The AREITL permits an Alabama real estate investment trust to indemnify and advance

		proceeding charging improper personal benefit to a director, if such director is adjudged liable on the basis that a personal benefit was improperly received. In cases where the director is wholly successful, on the merits or otherwise, in the defense of any proceeding instigated because of his or her status as a director, the TBCA mandates that the corporation indemnify the director against reasonable expenses incurred in the proceeding. Notwithstanding the foregoing, the TBCA provides that a court of competent jurisdiction, upon application, may order that a director or officer be indemnified for reasonable expense if, in consideration of all relevant circumstances, the court determines that such individual is fairly and reasonably entitled to indemnification, whether or not the standard of conduct set forth above was met. Officers, employees and agents who are not directors are entitled to the same degree of indemnification afforded to directors. MAA’s charter provides that its directors shall not be liable to MAA or its shareholders for monetary damages for breach of fiduciary duty except for: (1) any breach of the director’s duty of loyalty; (2) for acts or omissions not in good faith or which involve intentional misconduct or knowing violation of law; or (3) unlawful distributions as provided in the TBCA. MAA’s charter provides that MAA shall indemnify and advance expenses to a director, officer, employee or agent to the fullest extent permitted under the TBCA.		expenses to its trustees, officers, employees and agents to the same extent as permitted by certain sections of the ABCL for directors and officers of Alabama corporations. Pursuant to the Colonial declaration of trust, Colonial shall indemnify its shareholders and other employees and agents to such extent as shall be authorized by the Colonial Board or the Colonial bylaws and as permitted by law. To the maximum extent permitted under Alabama law, in effect from time-to-time, and after a preliminary determination of the ultimate entitlement to indemnification has been made in accordance with ABCL, the Colonial bylaws require Colonial to indemnify: • any present or former trustee or officer or any individual who, while a trustee or officer, served or is serving as a trustee, officer, director, shareholder or partner of another entity at Colonial’s express request, who has been successful, on the merits or otherwise, in the defense of a proceeding to which he was made a party by reason of service in such capacity, against reasonable expenses incurred by him in connection with the proceeding; and • any present or former trustee or officer or any individual who, while a trustee or officer, served or is serving as a trustee, officer, director, shareholder or partner of another entity at Colonial’s express request, who is made a party to a proceeding by reason of service in such capacity, against reasonable expenses incurred by him in connection with the proceeding, if: • he conducted himself in good faith; • he reasonably believed: • in the case of conduct in his official capacity with Colonial, that the conduct was in Colonial’s best interest; or • in all other cases, that the conduct was at least not opposed to Colonial’s best interests; and

				• in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful, provided, however, that the indemnification provided for in this clause will not be available if it is established that: • in connection with a proceeding by or in the right of Colonial, he was adjudged liable to Colonial; or • in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, he was adjudged liable on the basis that personal benefit was improperly received by him. In addition, the Colonial bylaws require Colonial to pay or reimburse, in advance of final disposition of a proceeding, reasonable expenses incurred by a present or former trustee or officer made a party to a proceeding by reason of such status; provided: • Colonial has received a written affirmation by the trustee or officer of his good faith belief that he has met the applicable standard of conduct necessary for indemnification by Colonial as authorized by the Colonial bylaws; • Colonial has received a written undertaking by or on his behalf to repay the amount paid or reimbursed by Colonial if it is ultimately determined that the applicable standard of conduct was not met; and • a determination is made, in accordance with Section 8.55 of the ABCL, that the facts then known to those making the determination would not preclude indemnification under the provisions of the bylaws. Colonial may, with the approval of the trustees, provide such indemnification and payment or reimbursement of expenses to

196


	Rights of MAA Shareholders (which will be the rights of shareholders of the Combined Corporation following the parent merger)	Rights of Colonial Shareholders

		any present or former trustee or officer who served a predecessor of Colonial and to any employee or agent of Colonial or a predecessor of Colonial.

Distributions	The MAA Board may authorize, and MAA may pay to shareholders, such dividends as the MAA Board in its absolute discretion shall determine after setting aside any funds deemed necessary by the board for creation of a reserve fund.	The Colonial declaration of trust provides that the Colonial Board may from time-to-time declare and pay to shareholders such dividends or distributions as the trustees shall determine in their discretion. The Colonial declaration of trust also provides that the trustees will endeavor to declare and pay distributions as necessary to qualify as a REIT under the Code; provided, however, that Colonial shareholders do not have any right to a distribution unless and until authorized and declared by the Colonial Board.

Dissenters’ Rights	The TBCA provides that a shareholder of a corporation is generally entitled to receive payment of the fair value of its stock if the shareholder dissents from transactions including a proposed merger, share exchange or a sale of substantially all of the assets of the corporation. However, dissenters’ rights generally are not available to holders of shares, such as shares of MAA common stock, that are registered on a national securities exchange or quoted on a national market security system.	The AREITL provides that each shareholder of an Alabama real estate investment trust objecting to a merger of the Alabama real estate investment trust shall have the same rights as an objecting shareholder of an Alabama business corporation under the ABCL and under the same procedures. The ABCL entitles a shareholder of an Alabama business corporation to dissent and obtain payment of the fair value of his or her shares, in the event of certain corporate actions including, without limitation, the consummation of a plan of merger to which the corporation is a party if shareholder approval is required for the merger by the statute or the articles of incorporation (or, in this case, the Colonial declaration of trust) and the shareholder is entitled to vote on the matter.

REIT Qualification	It is the duty of the MAA Board to ensure that MAA satisfies the requirements for qualification as a REIT. The MAA Board shall take no action to disqualify MAA as REIT or to otherwise revoke its election to be taxed as a REIT without the affirmative vote of 2/3rds of the number of shares of common stock entitled to vote on such a matter at a special meeting of MAA shareholders.	As set forth in the Colonial declaration of trust, the trustees will use their best efforts to carry out the fundamental investment policy of the trust and to conduct the affairs of the trust in such a manner as to continue to qualify the trust for the tax treatment provided in the REIT provisions of the Code. The Colonial declaration of trust provides that the Colonial Board may terminate the status of Colonial as a REIT, provided, the Colonial Board adopts and presents such a resolution at an annual or special meeting of the shareholders, and the resolution is approved by holders of a majority of the issued and outstanding Colonial common shares.

MID-AMERICA APARTMENT COMMUNITIES, INC.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Introduction

On June 3, 2013 Mid-America Apartment Communities, Inc., or MAA, and Colonial Properties Trust, or Colonial, and certain of their respective affiliates, entered into a definitive agreement and plan of merger, which is referred to as the merger agreement, pursuant to which MAA and Colonial will combine through a merger of Colonial with and into MAA, with MAA surviving the merger, which is referred to as the parent merger.

Under the terms of the merger agreement, each Colonial common share will be converted automatically into the right to receive 0.360 of a newly issued share of MAA common stock. Upon completion of the parent merger, we estimate that continuing MAA equity holders will own approximately 56% of the issued and outstanding shares of Combined Corporation common stock, assuming the conversion of all limited partnership units of MAA LP held by existing limited partners of MAA LP to shares of Combined Corporation common stock, and former Colonial equity holders will own approximately 44% of the issued and outstanding shares of common stock of the Combined Corporation, assuming the conversion of all limited partnership units issued by MAA LP to former limited partners of Colonial LP to shares of Combined Corporation common stock. The parent merger is subject to customary closing conditions, including receipt of the approval of both the MAA and Colonial shareholders, among other things. The transactions contemplated by the merger agreement, including the parent merger, are expected to close during the third quarter of 2013.

The following unaudited pro forma consolidated financial statements are based on MAA’s historical consolidated financial statements and Colonial’s historical consolidated financial statements, each incorporated by reference in this joint proxy statement/prospectus, and have been adjusted in the statements below to give effect to the parent merger transaction. The unaudited pro forma combined statements of operations for the three months ended March 31, 2013 and the twelve months ended December 31, 2012 give effect to the parent merger as if it had occurred on January 1, 2012, the beginning of the earliest period presented. The unaudited pro forma combined balance sheet as of March 31, 2013 gives effect to the parent merger as if it had occurred on March 31, 2013. The historical consolidated financial statements of Colonial have been adjusted to reflect certain reclassifications in order to conform to MAA’s financial statement presentation.

The unaudited pro forma consolidated financial statements were prepared using the acquisition method of accounting with MAA considered the acquirer of Colonial. See “The Parent Merger—Accounting Treatment”. Under the acquisition method of accounting, the purchase price is allocated to the underlying Colonial tangible and intangible assets acquired and liabilities assumed based on their respective fair market values with the excess purchase price, if any, allocated to goodwill.

The pro forma adjustments and the purchase price allocation as presented are based on estimates and certain information that is currently available. The total consideration for the parent merger and the assignment of fair values to Colonial’s assets acquired and liabilities assumed has not been finalized, is subject to change, could vary materially from the actual amounts at the time the parent merger is completed, and has not identified all adjustments necessary to conform Colonial’s accounting policies to MAA’s accounting policies. A final determination of the fair value of Colonial’s assets and liabilities, including intangible assets with both indefinite or finite lives, will be based on the actual net tangible and intangible assets and liabilities of Colonial that exist as of the closing date of the parent merger and, therefore, cannot be made prior to the completion of the parent merger. In addition, the value of the consideration to be paid by MAA upon the consummation of the parent merger will be determined based on the closing price of MAA’s common stock on the closing date of the parent merger. As a result of the foregoing, the pro forma adjustments are preliminary and are subject to change as additional information becomes available and as additional analyses are performed. The preliminary pro forma adjustments have been made solely for the purpose of providing the unaudited pro forma consolidated financial statements presented below. MAA estimated the fair value of Colonial’s assets and

F-2

liabilities based on discussions with Colonial’s management, preliminary valuation studies, due diligence and information presented in Colonial’s public filings. During the discussions, MAA learned that subsequent to March 31, 2013, Colonial sold a commercial property with net book value of $133.4 million, resulting in a gain of $9.4 million. This gain, and the removal of assets on the sale are not reflected in the unaudited pro forma consolidated financial statements, as the sale was not part of the merger transactions. Until the parent merger is completed, both companies are limited in their ability to share certain information. Upon completion of the parent merger, final valuations will be performed. Any increases or decreases in the fair value of relevant balance sheet amounts upon completion of the final valuations will result in adjustments to the pro forma balance sheet and/or statements of operations. The final purchase price allocation may be different than that reflected in the pro forma purchase price allocation presented herein, and this difference may be material.

The aggregate purchase price for financial statement purposes will be based on the actual closing price per share of MAA common stock on the closing date, which could differ materially from the assumed value disclosed in the notes to the unaudited pro forma consolidated financial statements. If the actual closing price per share of MAA common stock on the closing date is higher than the assumed amount, it is expected that the final purchase price will be higher; conversely, if the actual closing price is lower, it is expected that the final purchase price will be lower. A hypothetical 10% change in MAA’s closing stock price on the closing date of the parent merger would have an approximate $234 million impact on the purchase price and subsequent goodwill balance, if any.

Assumptions and estimates underlying the unaudited adjustments to the unaudited pro forma consolidated financial statements are described in the accompanying notes. The historical consolidated financial statements have been adjusted in the unaudited pro forma consolidated financial statements to give effect to pro forma events that are: (1) directly attributable to the parent merger, (2) factually supportable, and (3) expected to have a continuing impact on the results of operations of the Combined Corporation following the parent merger. This information is presented for illustrative purposes only and is not indicative of the combined operating results or financial position that would have occurred if such transactions had occurred on the dates and in accordance with the assumptions described below, nor is it indicative of future operating results or financial position.

The unaudited pro forma consolidated financial statements, although helpful in illustrating the financial characteristics of the Combined Corporation under one set of assumptions, do not reflect the benefits of expected cost savings (or associated costs to achieve such savings), opportunities to earn additional revenue, or other factors that may result as a consequence of the parent merger and do not attempt to predict or suggest future results. Specifically, the unaudited pro forma combined statements of operations exclude projected operating efficiencies and synergies expected to be achieved as a result of the parent merger. The projected operating synergies are expected to include approximately $25 million in combined annual cost synergies. The unaudited pro forma consolidated financial statements also exclude the effects of costs associated with any restructuring or integration activities or asset dispositions resulting from the parent merger as they are currently not known, and to the extent they occur, are expected to be non-recurring and will not have been incurred at the closing date of the parent merger. However, such costs could affect the Combined Corporation following the parent merger in the period the costs are incurred or recorded. Further, the unaudited pro forma consolidated financial statements do not reflect the effect of any regulatory actions that may impact the results of the Combined Corporation following the parent merger.

The unaudited pro forma consolidated financial statements have been developed from and should be read in conjunction with:

•

the accompanying notes to the unaudited pro forma consolidated financial statements;

•

the historical audited consolidated financial statements of MAA as of and for the year ended December 31, 2012, included in MAA’s Form 10-K, and the historical unaudited consolidated financial statements as of and for the three months ended March 31, 2013, included in MAA’s Form 10-Q, both of which are incorporated by reference in this document;

CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1:

Overview

For purposes of the unaudited pro forma consolidated financial statements (the “pro forma financial statements”), we have assumed a total preliminary purchase price for the parent merger of approximately $2.3 billion, which consists of shares of MAA common stock and common units in MAA LP, or MAA LP units, issued in exchange for Colonial LP units. Under the terms of the merger agreement, the transaction is currently valued at $24.40 per Colonial share/Colonial LP unit, based on the closing price of MAA’s common stock on July 11, 2013. Each issued and outstanding share of Colonial common stock will receive 0.360 of a share of MAA common stock totaling a maximum aggregate number of shares of MAA common stock of approximately 31.9 million shares. In addition to the shares of common stock, the transaction will also result in approximately 2.6 million additional MAA LP units from the exchange of Colonial LP units into new MAA LP units using the 0.360 exchange rate noted above. We estimate that the MAA stock price represents the fair value of the MAA LP units.

The pro forma financial statements have been prepared assuming the parent merger is accounted for using the acquisition method of accounting under U.S. GAAP (which we refer to as “acquisition accounting”) with MAA as the acquiring entity. Accordingly, under acquisition accounting, the total estimated purchase price is allocated to the acquired net tangible and identifiable intangible assets and liabilities assumed of Colonial based on their respective fair values, as further described below.

To the extent identified, certain reclassifications have been reflected in the pro forma adjustments to conform Colonial’s financial statement presentation to that of MAA, as described in Note 2. However, the unaudited pro forma financial statements may not reflect all adjustments necessary to conform the accounting policies of Colonial to those of MAA due to limitations on the availability of information as of the date of this joint proxy statement/prospectus.

The pro forma adjustments represent MAA management’s estimates based on information available as of the date of this joint proxy statement/prospectus and are subject to change as additional information becomes available and additional analyses are performed. The pro forma financial statements do not reflect the impact of possible revenue or earnings enhancements, cost savings from operating efficiencies or synergies, or asset dispositions. Also, the pro forma financial statements do not reflect possible adjustments related to restructuring or integration activities that have yet to be determined or transaction or other costs following the parent merger that are not expected to have a continuing impact. Further, one-time transaction-related expenses anticipated to be incurred prior to, or concurrent with, closing the parent merger are not included in the pro forma statements of operations.

The pro forma statements of operations for the year ended December 31, 2012 and for the three months ended March 31, 2013 combine the historical consolidated statements of operations of MAA and Colonial, giving effect to the mergers as if they had been consummated on January 1, 2012, the beginning of the earliest period presented. The pro forma balance sheet combines the historical consolidated balance sheet of MAA and the historical consolidated balance sheet of Colonial as of March 31, 2013, giving effect to the parent merger as if it had been consummated on March 31, 2013.

Completion of the parent merger is subject to, among other things, approval by the shareholders of both companies. As of the date of this joint proxy statement/prospectus, the parent merger is expected to be completed during the third quarter of 2013.

Preliminary Estimated Purchase Price

The total preliminary estimated purchase price of approximately $2.3 billion was determined based on the number of Colonial common shares and Colonial LP units, as of July 11, 2013. For purposes of the pro forma

F-8

MID-AMERICA APARTMENT COMMUNITIES, INC.

NOTES TO UNAUDITED PRO FORMA

CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

financial statements, such common shares and Colonial LP units are assumed to remain outstanding as of the closing date of the parent merger. Further, no effect has been given to any other new common shares or Colonial LP units that may be issued or granted subsequent to the date of this joint proxy statement/prospectus and before the closing date of the parent merger. In all cases in which MAA’s closing stock price is a determining factor in arriving at final consideration for the parent merger, the stock price assumed for the total preliminary purchase price is the closing price of MAA’s common stock on July 11, 2013 ($67.77 per share), the most recent date practicable in the preparation of this joint proxy statement/prospectus.

The purchase price will be computed using the closing price of MAA common stock on the closing date; therefore, the actual purchase price will fluctuate with the market price of MAA common stock until the parent merger is consummated. As a result, the final purchase price could differ significantly from the current estimate, which could materially impact the pro forma financial statements. For more information regarding the consideration exchanged in the parent merger, see “The Merger Agreement—Merger Consideration; Effects of the Parent Merger and the Partnership Merger.”

The following table presents the changes to the value of stock consideration and the total preliminary purchase price based on a 10% increase and decrease in the per share price of MAA common stock (in thousands, except per share data):


	Price of MAA Common Stock		Consideration Given (MAA Shares and MAA LP Units to be Issued)		Calculated Value of Consideration
As of July 11, 2013	$	67.77		34,523	$	2,339,596
Decrease of 10%	$	60.99		34,523	$	2,105,636
Increase of 10%	$	74.55		34,523	$	2,573,555

The total preliminary estimated purchase price described above has been allocated to Colonial’s tangible and intangible assets acquired and liabilities assumed for purposes of these pro forma financial statements, based on their estimated relative fair values assuming the parent merger was completed on the pro forma balance sheet date presented. The final allocation will be based upon valuations and other analyses for which there is currently insufficient information to make a definitive allocation. Accordingly, the purchase price allocation adjustments are preliminary and have been made solely for the purpose of providing pro forma financial statements. The final purchase price allocation will be determined after the parent merger is consummated and after completion of a thorough analysis to determine the fair value of Colonial’s tangible assets and liabilities, including fixed assets and identifiable intangible assets and liabilities. As a result, the final acquisition accounting adjustments, including those resulting from conforming Colonial’s accounting policies to those of MAA, could differ materially from the pro forma adjustments presented herein. The total preliminary purchase price was allocated as follows, based on Colonial’s historical unaudited consolidated Balance Sheet as of March 31, 2013 (in thousands):

The carrying value of hedging instruments was classified as a component of “Other liabilities.” This balance has been reclassified into “Fair market value of interest rate swaps.”

Statement of Operations

•

The components of property operating expense were combined into the line item titled “Property operating expense.” These balances have been reclassified into separate components titled “Personnel,” “Building repairs and maintenance,” “Utilities,” “Landscaping,” and “Other operating expenses.”

•

The expenses that make up the balance on the line titled “Impairment, legal contingencies, and other losses” were included as a component of “Operating income.” These expenses have been reclassified to “Non-operating income.”

Balance Sheet

•

A component of “Other assets” has been reclassified into a separate component, reclassifying $12.9 million to “Accounts receivable.”

Balance Sheet Adjustments

(B)

The real estate assets of Colonial have been adjusted to their estimated fair values as of March 31, 2013. A third party service provider was used to estimate the fair value generally by applying a capitalization rate to estimated net operating income, using recent third party appraisals, or other available market data. The preliminarily estimated purchase price allocation was performed using the closing stock price of MAA on July 11, 2013.

(C)

Colonial’s historical accumulated depreciation is eliminated since the assets were presented at estimated fair value.

(D)

Colonial’s investments in real estate joint ventures have been adjusted to their estimated fair value as of March 31, 2013, using valuation techniques similar to those used to estimate the fair value of wholly-owned assets as discussed in (B) above. A fair market value of debt adjustment for debt held by the joint ventures is included. Fair value was estimated based on contractual future cash flows discounted using borrowing spreads and market interest rates that would have been available for debt with similar terms and maturities.

(E)

Colonial’s assets held for sale are adjusted to reflect the assets at their estimated fair values less costs to sell.

(F)

Colonial’s historical deferred financing costs of $12.3 million, net, are eliminated.

(G)

Other assets adjustment includes $110.3 million for acquisition of acquired in place leases primarily related to commercial property, $13.1 million for leases that have above market rents, and $9.3 million for the elimination of Colonial straight line rent receivable. The estimated fair value of in place leases was calculated based upon the best estimate of the costs to obtain tenants, primarily leasing commissions, in each applicable market. An asset or liability is recognized for acquired leases with favorable or unfavorable rents based on our best estimates of current rents in each market.

(H)

The debt balances of Colonial have been adjusted to reflect the estimated fair value at March 31, 2013. Fair value was estimated based on contractual future cash flows discounted using borrowing spreads and market interest rates that would have been available for debt with similar terms and maturities.

(I)

Adjustment represents estimated transaction costs anticipated to be paid by MAA and Colonial prior to or concurrent with the closing of the parent merger of approximately $33.1 million, consisting primarily of fees for investment bankers, legal, accounting, tax, and certain filings to be paid to third parties based on actual expenses incurred to date and each party’s best estimate of its remaining fees as provided to MAA and Colonial. The adjustment does not include costs related to equity or debt financing and severance plans.

(J)

Other liabilities adjustment includes $1.9 million fair value adjustment related to a contingent liability.

(K)

Adjustment represents the elimination of all historical Colonial balances and the issuance of MAA common stock in the parent merger using a value of $67.77 per share as of July 11, 2013.

(L)

The adjustment to noncontrolling interest represents the allocation of equity to the limited partnership unitholders based on the estimated fair value assumptions above.

Statement of Operations Adjustment—March 31, 2013

(M)

Rental revenue is adjusted to reflect the amortization of the above/below market lease intangible. This resulted in a decrease of $0.7 million due to the above market lease intangible asset.

(N)

Depreciation and amortization is adjusted to remove $33.4 million of historical depreciation and amortization expense and to recognize $34.9 million of depreciation due to the fair value adjustment of the real estate assets and $3.0 million from the intangible assets recognized at estimated fair value. This depreciation and amortization adjustment is computed on a straight-line basis over the estimated useful lives of the related assets, which range from 30 years for land improvements and buildings, 5 years for furniture, fixtures, and equipment, 5 years amortization for acquired retail leases, and 6 months amortization for acquired residential leases, all of which are subjective determinations.

(O)

We expect the parent merger to create general and administrative cost efficiencies but there can be no assurance that such costs will be achieved. Since these costs are not factually supportable, we have not included any estimate of projected cost savings.

(P)

Interest expense is reduced by $4.1 million as the result of the amortization of the fair market value of debt adjustment as discussed in (H) above.

(Q)

Amortization of deferred financing cost is adjusted to remove $1.4 million of historical amortization.

(R)

Gain from real estate joint ventures is increased by $29,000 as the result of the amortization of the fair market value of debt adjustment as discussed in (D) above for debt held by joint ventures.

(S)

The adjustment to noncontrolling interest was made to reflect the limited partnership unitholders’ combined ownership percentage of 5.48% in the consolidated results of the Combined Corporation.

(b) Any and all Colonial Common Shares subject to Colonial Restricted Share Awards that are converted into the right to receive MAA Common Stock pursuant to Section 3.1(b) shall be converted into the

A-13

right to receive shares of MAA Common Stock that are subject to the same vesting and forfeiture conditions and other terms and conditions as are applicable to the Colonial Restricted Share Award immediately prior to the Parent Merger Effective Time.

(c) Prior to the Parent Merger Effective Time, Colonial and MAA agree that Colonial shall, and shall be permitted under this Agreement to, take all corporate action necessary to effectuate the provisions of this Section 3.4. From and after the Parent Merger Effective Time, unless the compensation committee of the MAA Board determines otherwise, all references to Colonial in the Colonial Equity Incentive Plans and in each agreement evidencing any Colonial Options or any other Colonial equity-based award, shall be deemed (A) for all purposes relating to employment, consultancy or directorship (or words of similar meaning) to refer to MAA and its Subsidiaries and (B) for all other purposes, to refer to MAA.

Section 3.5 Exchange of Certificates.

(a) Not less than five (5) days prior to dissemination of a joint proxy statement in preliminary and definitive form relating to the Colonial Shareholder Meeting and the MAA Shareholder Meeting (together with any amendments or supplements thereto, the “Joint Proxy Statement”), MAA shall appoint a bank or trust company reasonably satisfactory to Colonial to act as exchange agent (the “Exchange Agent”) for the payment and delivery of the Merger Consideration and the Fractional Share Consideration, as provided in Section 3.1(b) and Section 3.9. On or before the Partnership Merger Effective Time, MAA shall deposit, or cause to be deposited, with the Exchange Agent (i) evidence of MAA Common Stock in book-entry form issuable pursuant to Section 3.1(b) equal to the aggregate Merger Consideration, and (ii) cash in immediately available funds in an amount sufficient to pay the Fractional Share Consideration and any dividends under Section 3.5(d) (such evidence of book-entry shares of MAA Common Stock and cash amounts, together with any dividends or other distributions with respect thereto, the “Exchange Fund”), in each case, for the sole benefit of the holders of Colonial Common Shares. MAA shall cause the Exchange Agent to make, and the Exchange Agent shall make delivery of the Merger Consideration, payment of the Fractional Share Consideration and any amounts payable in respect of dividends or other distributions on shares of MAA Common Stock in accordance with Section 3.5(d) out of the Exchange Fund in accordance with this Agreement. The Exchange Fund shall not be used for any other purpose.

(b) The cash portion of the Exchange Fund shall be invested by the Exchange Agent as directed by MAA. Interest and other income on the Exchange Fund shall be the sole and exclusive property of MAA. No investment of the Exchange Fund shall relieve MAA or the Exchange Agent from making the payments required by this Article III, and following any losses from any such investment, MAA shall promptly provide additional funds to the Exchange Agent to the extent necessary to satisfy MAA’s obligations hereunder for the benefit of the holders of Colonial Common Shares at the Parent Merger Effective Time, which additional funds will be deemed to be part of the Exchange Fund.

(i) As promptly as practicable following the Parent Merger Effective Time (but in no event later than two (2) Business Days thereafter), MAA shall cause the Exchange Agent to mail (and to make available for collection by hand) to each holder of record of a Certificate or Book-Entry Share (A) a letter of transmittal (a “Letter of Transmittal”) which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or Book-Entry Shares shall pass only upon proper delivery of the Certificates or Book-Entry Shares (or affidavits of loss in lieu thereof) to the Exchange Agent, which Letter of Transmittal shall be in such form and have such other customary provisions as MAA and Colonial may reasonably agree upon, and (B) instructions for use in effecting the surrender of the Certificates or Book-Entry Shares in exchange for the Merger Consideration into which the number of Colonial Common Shares previously represented by such Certificate or Book-Entry Share shall have been converted pursuant to this Agreement, together with any amounts payable in respect of the

A-14

Fractional Share Consideration in accordance with Section 3.9 and dividends or other distributions on shares of MAA Common Stock in accordance with Section 3.5(d).

(ii) Upon surrender of a Certificate or Book-Entry Share (or affidavit of loss in lieu thereof) to the Exchange Agent, together with a Letter of Transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor the Merger Consideration for each Colonial Common Share formerly represented by such Certificate or Book-Entry Share pursuant to the provisions of this Article III plus any Fractional Share Consideration that such holder has the right to receive pursuant to the provisions of Section 3.9 and any amounts that such holder has the right to receive in respect of dividends or other distributions on shares of MAA Common Stock in accordance with Section 3.5(d) to be mailed or delivered by wire transfer, within two (2) Business Days following the later to occur of (A) the Parent Merger Effective Time or (B) the Exchange Agent’s receipt of such Certificate (or affidavit of loss in lieu thereof), and the Certificate (or affidavit of loss in lieu thereof) so surrendered shall be forthwith cancelled. The Exchange Agent shall accept such Certificates (or affidavits of loss in lieu thereof) upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with customary exchange practices. Until surrendered as contemplated by this Section 3.5, each Certificate and Book-Entry Share shall be deemed, at any time after the Parent Merger Effective Time, to represent only the right to receive, upon such surrender, the Merger Consideration as contemplated by this Article III. No interest shall be paid or accrued for the benefit of holders of the Certificates or Book-Entry Shares on the Merger Consideration or the Fractional Share Consideration payable upon the surrender of the Certificates or Book-Entry Shares and any distributions to which such holder is entitled pursuant to Section 3.5(d) hereof.

(iii) In the event of a transfer of ownership of Colonial Common Shares that is not registered in the transfer records of Colonial, it shall be a condition of payment that any Certificate or Book-Entry Share surrendered in accordance with the procedures set forth in this Section 3.5(c) shall be properly endorsed or shall be otherwise in proper form for transfer, and that the Person requesting such payment shall have paid any transfer Taxes and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate or Book-Entry Share surrendered or shall have established to the reasonable satisfaction of MAA that such Tax either has been paid or is not applicable.

(d) Dividends with Respect to MAA Common Stock. No dividends or other distributions with respect to MAA Common Stock with a record date after the Parent Merger Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of MAA Common Stock issuable hereunder, and all such dividends and other distributions shall be paid by MAA to the Exchange Agent and shall be included in the Exchange Fund, in each case until the surrender of such Certificate or Book-Entry Share (or affidavit of loss in lieu thereof) in accordance with this Agreement. Subject to applicable Laws, following surrender of any such Certificate or Book-Entry Share (or affidavit of loss in lieu thereof) there shall be paid to the holder thereof, without interest, (i) the amount of dividends or other distributions with a record date after the Parent Merger Effective Time theretofore paid with respect to such shares of MAA Common Stock to which such holder is entitled pursuant to this Agreement and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Parent Merger Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such shares of MAA Common Stock.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund (including any Fractional Share Consideration and any applicable dividends or other distributions with respect to MAA Common Stock) which remains undistributed to the holders of Colonial Common Shares for twelve (12) months after the Parent Merger Effective Time shall be delivered to MAA, upon demand, and any former holders of Colonial Common Shares prior to the Parent Merger who have not theretofore complied with this Article III shall thereafter look only to MAA for payment of the Merger Consideration.

A-15

(f) No Liability. None of the MAA Parties, the Colonial Parties, the Exchange Agent, or any employee, officer, director, agent or Affiliate thereof, shall be liable to any person in respect of the Merger Consideration, as applicable, if the Exchange Fund has been delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. Any amounts remaining unclaimed by holders of any such shares immediately prior to the time at which such amounts would otherwise escheat to, or become property of, any Governmental Authority shall, to the extent permitted by applicable Law, become the property of MAA, free and clear of any claims or interest of such holders or their successors, assigns or personal representatives previously entitled thereto.

Section 3.6 Withholding Rights. The Parties, Colonial LP, MAA LP, OP Merger Sub, the respective Affiliates of the foregoing and the Exchange Agent, as applicable, shall be entitled to deduct and withhold from the Merger Consideration and Fractional Share Consideration (and any other consideration otherwise payable pursuant to this Agreement or deemed paid for Tax purposes), such amounts as it is required to deduct and withhold with respect to such payments under the Code or any other provision of state, local or foreign Law. Any such amounts so deducted and withheld shall be paid over to the applicable Governmental Authority in accordance with applicable Law and shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

Section 3.7 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Colonial Common Shares that are outstanding immediately prior to the Parent Merger Effective Time and that are held by any Person who is entitled to dissent and properly perfects such Person’s dissenters’ rights of appraisal with respect to such Colonial Common Shares (the “Dissenting Shares”) pursuant to, and who complies in all respects with, Section 10A-2-13.01 et seq. of the ABNEC (“ABNEC Article 13”) shall not be converted into shares of MAA Common Stock as provided in Section 3.1(b), but rather the holders of Dissenting Shares shall be entitled to payment by MAA of the “fair value” (as defined in ABNEC Article 13) of such Dissenting Shares plus accrued interest in accordance with ABNEC Article 13; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to dissent under ABNEC Article 13, then the right of such holder to be paid the fair value of such holder’s Dissenting Shares shall cease and such Dissenting Shares shall be deemed to have been converted as of the Parent Merger Effective Time into, and shall have become exchangeable solely for the right to receive, shares of MAA Common Stock as provided in Section 3.1(b). Colonial shall serve prompt written notice to MAA of any demand received by Colonial from a holder of Colonial Common Shares pursuant to Section 13.21 of ABNEC Article 13, and MAA shall have the right to participate in all negotiations and proceedings with respect to any such demand. Prior to the Parent Merger Effective Time, Colonial shall not, without the prior written consent of MAA (not to be unreasonably withheld, delayed or conditioned), make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

Section 3.8 Structure. Each party hereto shall cooperate reasonably in the consideration of any reasonable changes requested by the other Parties regarding the structure of the transactions contemplated herein; provided, however, that no such change shall (a) alter or change the amount or kind of the consideration to be issued to holders of Colonial Common Shares or Colonial OP Units as currently contemplated in this Agreement, (b) reasonably be expected to impose any material impediment or delay, or condition to, consummation of the Mergers, (c) adversely affect, including with respect to federal income tax treatment, any of the parties hereto or the holders of Colonial Common Shares or Colonial OP Units in connection with the Mergers, (d) require submission to or approval by holders of Colonial Common Shares after the Colonial Shareholder Approval, (e) require submission to or approval by holders of Colonial OP Units (other than to the extent solely from Colonial, as general partner and/or limited partner of Colonial LP) or (f) provide for any modifications to the provisions of the Amended Partnership Agreement that are noted on Exhibit E as being “In The Form”; and provided further that such change also shall be subject to the written consent of the other Parties (such consent not to be unreasonably withheld, or conditioned or delayed). In the event that the Parties mutually agree to make such a change, the Parties agree to execute appropriate documents, including entering into appropriate amendments to this Agreement, to reflect the change.

A-16

Section 3.9 Fractional Shares. No certificate or scrip representing fractional shares of MAA Common Stock shall be issued upon the surrender for exchange of Certificates or the transfer of Book-Entry Shares, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of MAA. Notwithstanding any other provision of this Agreement, each holder of Colonial Common Shares converted pursuant to the Parent Merger who would otherwise have been entitled to receive a fraction of a share of MAA Common Stock shall receive, in lieu thereof, cash, without interest, in an amount equal to such fractional part of a share of MAA Common Stock multiplied by the VWAP of MAA Common Stock.

Section 3.10 Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, then upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by MAA, the posting by such Person of a bond in such reasonable amount as MAA may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration, Fractional Share Consideration and any distributions to which such holder is entitled pursuant to this Article III.

Colonial shall, through the Colonial Board, recommend to its shareholders that they vote in favor of the Parent Merger as contemplated by the Plan of Merger, include such recommendation in the Joint Proxy Statement and solicit and use its reasonable best efforts to obtain the Colonial Shareholder Approval, except to the extent that the Colonial Board shall have made a Change in Colonial Recommendation as permitted by Section 7.4(b) and subject to the exercise of Colonial’s rights with respect to a Superior Proposal under Section 7.4.

A-62

Approval, whether or not a quorum is present, Colonial shall have the right to make one or more successive postponements or adjournments of the Colonial Shareholder Meeting; provided, that the Colonial Shareholder Meeting is not postponed or adjourned to a date that is more than thirty (30) days after the date for which the Colonial Shareholder Meeting was originally scheduled (excluding any postponement or adjournments required by applicable Law).

Section 7.2 Access to Information.

(a) During the Interim Period, to the extent permitted by applicable Law and contracts, and subject to reasonable restrictions described in writing imposed from time to time upon advice of counsel, each of Colonial and MAA shall, and shall cause each of the Colonial Subsidiaries and the MAA Subsidiaries, respectively, to, afford to the other Party and to the Representatives of such other Party reasonable access during normal business hours and upon reasonable advance notice to all of their respective properties, offices, books, contracts, commitments, personnel and records and, during such period, each of Colonial and MAA shall, and shall cause each of the Colonial Subsidiaries and the MAA Subsidiaries, respectively, to, (i) furnish reasonably promptly to the other Party a copy of each report, schedule, registration statement and other document filed by it during such period pursuant to the requirements of federal or state securities Laws, and (ii) furnish, upon reasonable request, all other information (financial or otherwise) concerning its business, properties and personnel as such other Party may reasonably request. No representation or warranty as to the accuracy of information provided pursuant to this Section 7.2 is made and the Parties may not rely on the accuracy of such information except to the extent expressly set forth in the representations and warranties included in Article IV or Article V, and no investigation under this Section 7.2 or otherwise shall affect any of the representations and warranties of the Colonial Parties or of the MAA Parties, respectively, contained in this Agreement or any condition to the obligations of the Parties under this Agreement. Notwithstanding the foregoing, neither Colonial nor MAA shall be required by this Section 7.2 to provide the other Party or the Representatives of such other Party with access to or to disclose information (x) that is subject to the terms of a confidentiality agreement with a third party entered into prior to the date of this Agreement or entered into after the date of this Agreement in the ordinary course of business consistent with past practice (if Colonial or MAA, as applicable, has used reasonable best efforts to obtain

A-63

permission or consent of such third party to such disclosure), (y) the disclosure of which would violate any Law or legal duty of the Party or any of its Representatives or (z) that is subject to any attorney-client, attorney work product or other legal privilege or would cause a risk of a loss of privilege to the disclosing Party. Each of Colonial and MAA will use its reasonable best efforts to minimize any disruption to the businesses of the other Party that may result from the requests for access, data and information hereunder. Prior to the Partnership Merger Effective Time, each of the Colonial Parties and each of the MAA Parties shall not, and shall cause their respective Representatives and Affiliates not to, contact or otherwise communicate with parties with which the other Party has a business relationship (including tenants/subtenants) regarding the business of such other Party or this Agreement and the transactions contemplated hereby without the prior written consent of such other Party (provided that, for the avoidance of doubt, nothing in this Section 7.2(a) shall be deemed to restrict a Party and its respective Representatives and Affiliates from contacting such parties in pursuing its own business activities (operating in the ordinary course)).

(b) Each of Colonial and MAA will hold, and will cause its respective Representatives and Affiliates to hold, any nonpublic information, including any information exchanged pursuant to this Section 7.2, in confidence to the extent required by and in accordance with, and will otherwise comply with, the terms of the Confidentiality Agreement, which shall remain in full force and effect pursuant to the terms thereof notwithstanding the execution and delivery of this Agreement or the termination thereof.

(c) Each of Colonial and MAA will give prompt written notice to the other upon becoming aware of the occurrence or impending occurrence of any event or circumstance relating to it or any of the Colonial Subsidiaries or the MAA Subsidiaries, respectively, which could reasonably be expected to have, individually or in the aggregate, a Colonial Material Adverse Effect or a MAA Material Adverse Effect, as the case may be.

(d) Each Party shall cooperate and participate, as reasonably requested by the other Party from time to time, in efforts to oversee the integration of the Parties’ operations in connection with, and taking effect upon consummation of, the Mergers subject to applicable Law, including, without limitation, providing such reports on operational matters and participating on such teams and committees as the Parties shall mutually agree.

Section 7.3 Reasonable Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each of the Parties hereto shall use its reasonable best efforts (subject to, and in accordance with, applicable Law) to take, or cause to be taken, all actions and to do promptly, or cause to be done promptly, and to assist and cooperate with each other in doing, all things necessary, proper or advisable under applicable Law to consummate and make effective, as promptly as practicable, the Mergers and the other transactions contemplated by this Agreement, including preparing and filing as promptly as practicable all documentation to effect all required filings, notices, petitions, statements, registrations, submissions of information, applications and other documents necessary to consummate the Mergers and the other transactions contemplated by this Agreement. In furtherance and not in limitation of the foregoing, each of the Parties hereto agrees to use its reasonable best efforts to (i) cooperate with the other Party in determining which filings are required to be made prior to the Closing with, and which consents, clearances, approvals, permits or authorizations are required to be obtained prior to the Closing from, any Governmental Authority in connection with the execution and delivery of this Agreement and the consummation of the Mergers and the other transactions contemplated hereby and in timely making all such filings, (ii) promptly furnish the other Party, subject in appropriate cases to appropriate confidentiality agreements to limit disclosure to outside lawyers and consultants, with such information and reasonable assistance as such other Party and its Affiliates may reasonably request in connection with their preparation of necessary filings, registrations and submissions of information to any Governmental Authority with respect to this Agreement or the transactions contemplated hereby, (iii) supply as promptly as reasonably practicable and to the extent necessary any additional information and documentary material that may be requested pursuant to any applicable Laws by any Governmental Authority, and (iv) take or cause to be taken all other actions necessary, proper or advisable to obtain applicable clearances, consents, authorizations, approvals or waivers and cause the expiration or termination of the

A-64

applicable waiting periods with respect to the Mergers under any applicable Laws as promptly as reasonably practicable and, in any event, no later than the Outside Date.

(b) Subject to the terms and conditions of this Agreement, each of the Parties hereto shall, in connection with the efforts referenced in Section 5.3(a), use its reasonable best efforts to: (i) cooperate in all respects with each other in connection with any investigation or other inquiry, including any proceeding initiated by a private party with respect to this Agreement or the transactions contemplated hereby; (ii) promptly notify the other Party of any material communication concerning this Agreement or any of the transactions contemplated hereby to that Party from or with any Governmental Authority and consider in good faith the views of the other Party and keep the other Party reasonably informed of the status of matters related to the transactions contemplated by this Agreement, including furnishing the other with copies of any written notices or other material communications received by such Party from, or given by such Party to, any U.S. or foreign Governmental Authority and of any material communication received or given in connection with any proceeding by a private party, in each case regarding any of the transactions contemplated hereby, except that any materials concerning one Party’s valuation of the other Party may be redacted; and (iii) to the extent reasonably practicable, permit the other Party to review in draft any proposed written communication to be submitted by it to any Governmental Authority with reasonable time and opportunity to comment, and consult with each other in advance of any in-person or telephonic meeting or conference with any Governmental Authority or, in connection with any proceeding by a private party with respect to this Agreement or the transactions contemplated hereby, with any other Person, and, to the extent permitted by the applicable Governmental Authority or Person, use reasonable best efforts not to participate in any meeting or discussion with any Governmental Authority relating to any filings or investigations concerning this Agreement or any of the transactions contemplated hereby unless it consults with the other Party and its Representatives in advance and so long as it is acceptable to the Governmental Authority invites the other Party’s Representatives to attend in accordance with applicable Laws. The Parties may, as they deem advisable and necessary, designate competitively sensitive information provided to the other under this Section 7.3 as “outside counsel only.” Such materials and the information contained therein shall be given only to outside counsel of the recipient and will not be disclosed by such outside counsel to employees, officers, or directors of the recipient without the advance written consent of the Party providing such materials.

(c) In furtherance and not in limitation of the foregoing, subject to the terms and conditions of this Agreement, each of the Parties hereto shall (i) use its reasonable best efforts to resolve objections, if any, as may be asserted with respect to the transactions contemplated by this Agreement under any Laws, including defending any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby (including seeking to have any stay, temporary restraining order or preliminary injunction entered by any court or other Governmental Authority vacated or reversed), and (ii) take, or cause to be taken, all such further reasonable actions as may be necessary to resolve such objections, if any, as any Governmental Authority or any other Person may assert under any Law with respect to the Mergers and the other transactions contemplated hereby, and to avoid or eliminate each and every impediment under any Law so as to enable the Closing to occur as promptly as reasonably practicable and, in any event, no later than the Outside Date , including (but only with the prior written consent of the other Party) (x) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture, license or disposition of any assets of MAA, Colonial or any of their respective Subsidiaries or Affiliates, and (y) otherwise taking or committing to take any actions that after the Closing would limit the freedom of MAA, Colonial or their respective Subsidiaries’ or Affiliates’ freedom of action with respect to one or more of MAA’s, Colonial’s or their Subsidiaries’ businesses or assets, in each case as may be required in order to effect the satisfaction of the conditions to the Mergers set forth in Article VIII and to avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order in any suit or proceeding that would otherwise have the effect of preventing or delaying the Closing; provided, however, that neither MAA nor Colonial shall be required to become subject to, or consent or agree to or otherwise take any action with respect to, any Order, requirement, condition, understanding or agreement of or with a Governmental Authority to sell, to license, to hold separate or otherwise dispose of, or to conduct, restrict, operate, or otherwise change

A-65

their assets or businesses, unless such Order, requirement, condition, understanding or agreement is conditioned upon the occurrence of the Closing. Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 7.3 shall limit a Party’s right to terminate this Agreement pursuant to Section 9.1 so long as such Party has, prior to such termination, been complying with its obligations under this Section 7.3.

(d) Each of MAA and Colonial shall, if any Takeover Statute becomes applicable to this Agreement, the Mergers, or any other transactions contemplated hereby or thereby, grant approvals and use all reasonable best efforts to ensure that the Mergers and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby or thereby and otherwise to minimize the effect of such Takeover Statute on this Agreement, the Mergers and the other transactions contemplated hereby.

Section 7.4 Acquisition Proposals; Changes in Recommendation.

(a) Each of MAA and Colonial agrees that it shall not, nor shall it permit any of its Subsidiaries to, authorize or permit any of its officers, trustees, directors or employees to, and shall use its reasonable best efforts to cause its and its Subsidiaries’ Representatives not to, directly or indirectly, (i) initiate, solicit or knowingly encourage or knowingly facilitate any inquiries or the making of any proposal or offer by or with a Third Party with respect to (A) any merger, consolidation, share exchange, business combination or similar transaction involving it or any of its Subsidiaries, (B) any sale, lease, exchange, mortgage, pledge, license, transfer or other disposition, directly or indirectly, by merger, consolidation, sale of equity interests, share exchange, joint venture, business combination or otherwise, of any of its assets or that of its Subsidiaries (including stock or other ownership interests of its Subsidiaries) representing twenty percent (20%) or more of consolidated assets, as determined on a book-value basis, (C) any issue, sale or other disposition of (including by way of merger, consolidation, joint venture, business combination, share exchange or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into, such securities) representing twenty percent (20%) or more of its voting power, (D) any tender offer or exchange offer in which any Person or “group” (as such term is defined in Rule 13d-3 promulgated under the Exchange Act) shall seek to acquire beneficial ownership (as such term is defined in Rule 13d-3 promulgated under the Exchange Act), or the right to acquire beneficial ownership, of twenty percent (20%) or more of the outstanding shares of any class of its voting securities, or (E) any recapitalization, restructuring, liquidation, dissolution or other similar type of transaction in which a Third Party shall acquire beneficial ownership of twenty percent (20%) or more of the outstanding shares of any class of its voting securities (any such proposal, offer or transaction (other than a proposal or offer made by one Party to this Agreement or an Affiliate thereof) being hereinafter referred to as an “Acquisition Proposal”), (ii) engage in any negotiations concerning, or provide any confidential information or data to any person relating to an Acquisition Proposal, or knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal, (iii) approve or execute or enter into any letter of intent, agreement in principle, merger agreement, asset purchase or share exchange agreement, option agreement or other similar agreement related to any Acquisition Proposal (an “Acquisition Agreement”), or (iv) propose publicly or agree to do any of the foregoing.

(b)

(i) Notwithstanding the foregoing, the Colonial Board and MAA Board shall each be permitted, prior to its respective meeting of shareholders to be held pursuant to Section 7.1(c) or (d), as applicable, and subject to compliance with the other terms of this Section 7.4 and to first entering into a confidentiality agreement having provisions that are no less favorable to such party than those contained in the Confidentiality Agreement, to engage in discussions and negotiations with, or provide any nonpublic information or data to, any Person in response to an unsolicited bona fide written Acquisition Proposal by such Person made after the date of this Agreement (that did not result from a breach of this Section 7.4) and which the Colonial Board or the MAA Board, as applicable, concludes in good faith (after consultation with outside legal counsel and financial advisors) constitutes or is

A-66

reasonably likely to lead to a Superior Proposal, if and only to the extent that the directors of MAA or the trustees of Colonial, as applicable, conclude in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with their duties under applicable Law. Colonial and MAA, as applicable, shall provide the other with a copy of any nonpublic information or data provided to a third party pursuant to the prior sentence prior to or simultaneously with furnishing such information to such third party.

(ii) Each Party shall notify the other Party promptly (but in no event later than one Business Day) after receipt of any Acquisition Proposal, or any request for nonpublic information relating to such Party or any of its Subsidiaries by any person that informs such Party or any of its Subsidiaries that it is considering making, or has made, an Acquisition Proposal, or any inquiry from any person seeking to have discussions or negotiations with such Party relating to a possible Acquisition Proposal. Such notice shall be made orally and confirmed in writing, and shall indicate the identity of the person making the Acquisition Proposal, inquiry or request and the material terms and conditions of any inquiries, proposals or offers (including a copy thereof if in writing and any related documentation or correspondence). Each Party shall also promptly, and in any event within one Business Day, notify the other Party, orally and in writing, if it enters into discussions or negotiations concerning any Acquisition Proposal or provides nonpublic information or data to any person in accordance with this Section 7.4(b) and keep the other Party informed in all material respects of the status and terms of any such proposals, offers, discussions or negotiations on a current basis, including by providing a copy of all material documentation or correspondence relating thereto.

(iii) Except as provided in Section 7.4(b)(iv) or Section 7.4(b)(v), neither the Colonial Board, the MAA Board, nor any committee thereof shall withhold, withdraw or modify in any manner adverse to the other Party, or propose publicly to withhold, withdraw or modify in any manner adverse to the other Party, the approval, recommendation or declaration of advisability by the Colonial Board or the MAA Board, as applicable, or any such committee thereof with respect to this Agreement or the transactions contemplated hereby (a “Change in Colonial Recommendation” or a “Change in MAA Recommendation,” respectively).

(iv) Notwithstanding anything in this Agreement to the contrary, with respect to an Acquisition Proposal, the Colonial Board or the MAA Board, as applicable, may make a Change in Colonial Recommendation or a Change in MAA Recommendation, as applicable (and in the event that the Colonial Board or the MAA Board, as applicable, determines such Acquisition Proposal to be a Superior Proposal, in accordance with this Section 7.4, terminate this Agreement pursuant to Section 9.1), if and only if (A) an unsolicited bona fide written Acquisition Proposal (that did not result from a breach of this Section 7.4) is made to Colonial or MAA, as applicable, and is not withdrawn, (B) the Colonial Board or the MAA Board, as applicable, has concluded in good faith (after consultation with outside legal counsel and financial advisors) that such Acquisition Proposal constitutes a Superior Proposal, (C) the trustees of Colonial or the directors of MAA, as applicable, have concluded in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with their duties under applicable Law, (D) four (4) Business Days (the “Notice Period”) shall have elapsed since the Party proposing to take such action has given written notice to the other Party advising such other Party that the notifying Party intends to take such action and specifying in reasonable detail the reasons therefor, including the terms and conditions of any such Superior Proposal that is the basis of the proposed action (a “Notice of Recommendation Change”), (E) during such Notice Period, the notifying Party has considered and, at the reasonable request of the other Party, engaged in good faith discussions with such Party regarding, any adjustment or modification of the terms of this Agreement proposed by the other Party, and (F) the directors or trustees, as applicable, of the Party proposing to take such action, following such Notice Period, again reasonably determines in good faith (after consultation with outside legal counsel, and taking into account any adjustment or modification of the terms of this Agreement proposed by the other Party) that failure to do so would be inconsistent with their duties under applicable Law; provided, however,

A-67

that (1) if, during the Notice Period, any material revisions are made to the Superior Proposal (it being understood that a material revision shall include, without limitation, any change in the purchase price or form of consideration in such Superior Proposal), the Colonial Board or the MAA Board, as applicable, shall give a new written notice to the other Party and shall comply with the requirements of this Section 7.4(b)(iv) with respect to such new written notice and (2) in the event the Colonial Board or the MAA Board, as applicable, does not determine that such Acquisition Proposal is a Superior Proposal, but thereafter determines to make a Change in Colonial Recommendation or a Change in MAA Recommendation, as applicable, pursuant to this Section 7.4 with respect to an Acquisition Proposal, the foregoing procedures referred to in this Section 7.4(b)(iv) shall apply anew and shall also apply to any subsequent withdrawal, amendment or change with respect thereto.

(v) Notwithstanding anything in this Agreement to the contrary, in circumstances not involving or relating to an Acquisition Proposal, the Colonial Board or the MAA Board, as applicable, may make a Change in Colonial Recommendation or a Change in MAA Recommendation, as applicable, if and only if (A) a material development or change in circumstances has occurred or arisen after the date of this Agreement that was neither known to such Party nor reasonably foreseeable as of the date of this Agreement (and which change or development does not relate to an Acquisition Proposal), (B) the directors or trustees, as applicable, of the Party proposing to take such action have first reasonably determined in good faith (after consultation with outside legal counsel) that failure to do so would be inconsistent with their duties under applicable Law, (C) four (4) Business Days (the “Intervening Event Notice Period”) shall have elapsed since the Party proposing to take such action has given a Notice of Recommendation Change to the other Party advising that the notifying Party intends to take such action and specifying in reasonable detail the reasons therefor, (D) during such four-Business-Day period, the notifying Party has considered and, at the reasonable request of the other Party, engaged in good faith discussions with such Party regarding, any adjustment or modification of the terms of this Agreement proposed by the other Party, and (E) the directors or trustees, as applicable, of the Party proposing to take such action, following such Intervening Event Notice Period, again reasonably determine in good faith (after consultation with outside legal counsel, and taking into account any adjustment or modification of the terms of this Agreement proposed by the other Party) that failure to do so would be inconsistent with their duties under applicable Law; provided, however, that in the event the Colonial Board or the MAA Board, as applicable, does not make a Change in Colonial Recommendation or a Change in MAA Recommendation, as applicable, following such four-Business-Day period, but thereafter determines to make a Change in Colonial Recommendation or a Change in MAA Recommendation, as applicable, pursuant to this Section 7.4 in circumstances not involving an Acquisition Proposal, the foregoing procedures referred to in this Section 7.4(b)(v) shall apply anew and shall also apply to any subsequent withdrawal, amendment or change.

(vi) Nothing contained in this Section 7.4 shall prohibit either Party or its Subsidiaries from taking and disclosing to its respective shareholders a position contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making a statement contemplated by Item 1012(a) of Regulation M-A or Rule 14d-9 promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement pending disclosure of its position thereunder; provided, however, that compliance with such rules shall not in any way limit or modify the effect that any action taken pursuant to such rules has under any other provision of this Agreement, including Section 7.1(c) or (d), as applicable, and provided, further, that any such disclosure that addresses the approval, recommendation or declaration of advisability by the Colonial Board or the MAA Board, as applicable, with respect to this Agreement or an Acquisition Proposal shall be deemed to be a Change in Colonial Recommendation or Change in MAA Recommendation, as applicable, unless the Colonial Board or the MAA Board, as applicable, of such party, in connection with such communication publicly states that its recommendation with respect to this Agreement and the transactions contemplated hereby has not changed or refers to the prior recommendation of such party, without disclosing any Change in Colonial Recommendation or Change in MAA Recommendation, as applicable.

A-68

(c) For purposes of this Section 7.4 and this Agreement, “Superior Proposal” means a written bona fide Acquisition Proposal (except that, for purposes of this definition, the references in the definition of “Acquisition Proposal” to “twenty percent (20%)” shall be replaced by “fifty percent (50%)”) made by a Third Party on terms that the Colonial Board or the MAA Board, as applicable, determines in its good faith judgment, after consultation with outside legal counsel and financial advisors, taking into account all financial, legal, regulatory and any other aspects of the transaction described in such proposal and such other relevant factors (including, without limitation, the identity of the Person making such proposal, any break-up fees, expense reimbursement provisions, conditions to consummation and feasibility and certainty of consummation (including whether consummation is reasonably capable of being completed on a timely basis on the terms proposed), as well as any changes to the financial terms of this Agreement proposed by the other Party in response to such proposal or otherwise), would, if consummated, be more favorable to Colonial and its shareholders, or to MAA and its shareholders, as applicable, from a financial point of view than the transactions contemplated by this Agreement.

(d) Each of Colonial and MAA agrees that (i) it will and will cause its Subsidiaries, and its and their Representatives to, cease immediately and terminate any and all existing activities, discussions or negotiations with any third parties conducted heretofore with respect to any Acquisition Proposal, and (ii) it will not release any third party from, or waive any provisions of, any confidentiality or standstill agreement to which it or any of its Subsidiaries is a party with respect to any Acquisition Proposal. Each of Colonial and MAA agrees that it will use its reasonable best efforts to promptly inform its and its Subsidiaries’ respective Representatives of the obligations undertaken in this Section 7.4.

(e)

(i) Notwithstanding any Change in Colonial Recommendation or Change in MAA Recommendation, as applicable, unless such Change in Colonial Recommendation or Change in MAA Recommendation, as applicable, is with respect to a Superior Proposal and this Agreement is terminated pursuant to Section 9.1, each of Colonial and MAA shall cause the adoption of this Agreement to be submitted to a vote of its respective shareholders at the Colonial Shareholder Meeting and the MAA Shareholder Meeting, respectively.

(ii) Without the prior written consent of each of Colonial and MAA (which shall not be unreasonably withheld, conditioned or delayed), or otherwise as set forth on Section 7.4(e)(ii) of the Colonial Disclosure Letter or MAA Disclosure Letter, adoption of this Agreement and approval of the Mergers and the other transactions contemplated hereby is the only matter, other than any say-on-golden parachute vote that may be required pursuant to Section 14A(b)(2) of the Exchange Act and Rule 14a-21(c) thereunder and a proposal to approve the adjournment of the Colonial Shareholders Meeting or the MAA Shareholders Meeting, as applicable, if necessary, to solicit additional proxies, in the event that there are not sufficient votes at the time of the Colonial Shareholders Meeting or the MAA Shareholders Meeting, as applicable, to obtain the approval of Colonial’s shareholder or MAA’s shareholders, as applicable, which either Colonial or MAA, as applicable, shall propose to be acted on by its respective shareholders at the Colonial Shareholders Meeting or the MAA Shareholders Meeting, as applicable.

(iii) Notwithstanding anything to the contrary set forth in this Section 7.4 or elsewhere in this Agreement, if either Colonial or MAA, as applicable, receives a written Acquisition Proposal from any third Person following the date hereof, and not as a result of a violation of this Section 7.4, then Colonial or MAA, as applicable, or its respective Representatives, may contact such third Person in writing solely for the purpose of clarifying such Acquisition Proposal (the “Clarification Request”); provided, however, that Colonial shall deliver a copy of all Clarification Requests to MAA, and MAA shall deliver a copy of all Clarification Requests to Colonial, in each case concurrently with the delivery of such Clarification Requests to any third Person.

A-69

(f) References in this Section 7.4 to the Colonial Board or the MAA Board shall mean the board of trustees of Colonial or the board of directors of MAA, as applicable, or a duly authorized committee thereof.

(g) Neither party shall submit to the vote of its respective shareholders any Acquisition Proposal other than the Mergers prior to the termination of this Agreement.

Section 7.5 Public Announcements. Except with respect to any Change in Colonial Recommendation, Change in MAA Recommendation or any action taken by Colonial or the Colonial Board, or by MAA or the MAA Board, pursuant to and in accordance with Section 7.4, so long as this Agreement is an effect, the Parties hereto shall consult with each other before issuing any press release or otherwise making any public statements or filings with respect to this Agreement or any of the transactions contemplated by this Agreement, and none of the Parties shall issue any such press release or make any such public statement or filing prior to obtaining the other Parties’ consent (which consent shall not be unreasonably withheld, conditioned or delayed); provided, however, that a Party may, without obtaining the other Parties’ consent, issue such press release or make such public statement or filing as may be required by Law, Order or the applicable rules of any stock exchange if for any reason it is not reasonably practicable to consult with the other Party before making any public statement with respect to this Agreement or any of the transactions contemplated by this Agreement.

Section 7.6 Indemnification; Directors’ and Officers’ Insurance.

(a) Without limiting any additional rights that any manager, director, officer, trustee, agent, or fiduciary may have under any indemnification agreement or under the Colonial Declaration of Trust, the Colonial Bylaws, the Colonial LP Agreement or, if applicable, similar organizational documents or agreements of any Colonial Subsidiary (the “Organizational Documents”) from and after the Parent Merger Effective Time, MAA and MAA LP (the “Indemnifying Parties”), jointly and severally, shall: (i) indemnify and hold harmless each person who is at the date hereof, was previously, or during the period from the date hereof through the date of the Parent Merger Effective Time, serving as a manager, director, officer, trustee or fiduciary of Colonial or any of the Colonial Subsidiaries and acting in such capacity (collectively, the “Indemnified Parties”) to the fullest extent authorized or permitted by applicable Law, as now or hereafter in effect, in connection with any Claim and any losses, claims, damages, liabilities, costs, Claim Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of any thereof) relating to or resulting from such Claim; and (ii) promptly pay on behalf of or, within ten (10) Business Days after any request for advancement, advance to each of the Indemnified Parties, to the fullest extent authorized or permitted by applicable Law, as now or hereafter in effect, any Claim Expenses incurred in defending, serving as a witness with respect to or otherwise participating with respect to any Claim in advance of the final disposition of such Claim, including payment on behalf of or advancement to the Indemnified Party of any Claim Expenses incurred by such Indemnified Party in connection with enforcing any rights with respect to such indemnification and/or advancement, in each case without the requirement of any bond or other security, but subject to MAA’s receipt of an undertaking by or on behalf of such Indemnified Party to repay such Claim Expenses if it is ultimately determined under applicable Laws or any of the Organizational Documents that such Indemnified Party is not entitled to be indemnified; provided, however, that none of the Indemnifying Parties shall be liable for any amounts paid in settlement effected without MAA’s prior written consent and shall not be obligated to pay the fees and expenses of more than one counsel (selected by a plurality of the applicable Indemnified Parties) for all Indemnified Parties in any jurisdiction with respect to any single Claim except to the extent an Indemnified Party is advised by counsel that such Indemnified Party has conflicting interests with one or more other Indemnified Parties in the outcome of such action (in which event such Indemnified Party shall be entitled to engage separate counsel, the fees and expenses for which the Indemnifying Parties shall be liable); provided, further, that if, at any time prior to the sixth (6th) anniversary of the Partnership Merger Effective Time, any Indemnified Party delivers to MAA or MAA LP a written notice asserting that indemnification is

A-70

required in accordance with this Section 7.6 with respect to a Claim, then the provisions for indemnification contained in this Section 7.6 with respect to such Claim shall survive the sixth (6th) anniversary of the Partnership Merger Effective Time until such time as such Claim is fully and finally resolved. The indemnification and advancement obligations of the Indemnifying Parties pursuant to this Section 7.6(a) shall extend to acts or omissions occurring at or before the Parent Merger Effective Time and any Claim relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement, the Mergers and the consummation of the other transactions contemplated by this Agreement, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim relating thereto), and all rights to indemnification and advancement conferred hereunder shall continue as to a person who has ceased to be a director, officer, trustee, employee, agent, or fiduciary of Colonial or any of the Colonial Subsidiaries after the date hereof and shall inure to the benefit of such person’s heirs, executors and personal and legal representatives. As used in this Section 7.6(a): (x) the term “Claim” means any threatened, asserted, pending or completed Action or inquiry, whether civil, criminal, administrative, investigative or otherwise, including any arbitration or other alternative dispute resolution mechanism, and whether instituted by any Party hereto, any Governmental Authority or any other Person arising out of or pertaining to matters that relate to such Indemnified Party’s duties (including with respect to any acts or omissions occurring in connection with the approval of this Agreement, the Mergers and the consummation of the other transactions contemplated by this Agreement, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim relating thereto) or service as a manager, director, officer, trustee, employee, agent or fiduciary of Colonial or, any of the Colonial Subsidiaries or, to the extent such person is or was serving at the request or for the benefit of Colonial or any of the Colonial Subsidiaries, any other entity or any Employee Benefit Plan maintained by any of the foregoing at or prior to the Parent Merger Effective Time; and (y) the term “Claim Expenses” means reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Claim, including any Action relating to a claim for indemnification or advancement brought by an Indemnified Party as contemplated in this Section 7.6. No Indemnifying Party shall settle, compromise or consent to the entry of any judgment in, or seek termination with respect to, any actual or threatened Claim in respect of which indemnification may be sought by an Indemnified Party hereunder unless such settlement, compromise or judgment includes an unconditional release of such Indemnified Parties from all liability arising out of such Claim. No Indemnified Party shall be liable for any amounts paid in any settlement effected without its prior express written consent.

(b) Without limiting the foregoing, MAA agrees that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Parent Merger Effective Time now existing in favor of the current or former trustees, directors, officers, agents or fiduciaries of Colonial or any of the Colonial Subsidiaries as provided in the Organizational Documents and indemnification agreements of Colonial shall survive the Parent Merger and shall continue in full force and effect in accordance with their terms. For a period of six (6) years from the Parent Merger Effective Time, (i) MAA shall and shall cause the MAA Subsidiaries (including MAA LP) to honor and fulfill in all respects the obligations of MAA and the MAA Subsidiaries (including MAA LP) to the Indemnified Parties under the Organizational Documents and any indemnification agreement of Colonial or any Colonial Subsidiary entered into prior to the Partnership Merger Effective Time and (ii) the MAA charter and bylaws and the limited partnership agreement of MAA LP and the organizational documents of any applicable Colonial Subsidiary shall contain provisions no less favorable with respect to indemnification and limitations on liability of directors and officers than are set forth in the Organizational Documents, which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years from the Parent Merger Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Parent Merger Effective Time, were directors, officers, trustees, agents or fiduciaries of Colonial or any of the Colonial Subsidiaries, unless such modification shall be required by applicable Law and then only to the minimum extent required by applicable Law.

A-71

(c) Prior to the Partnership Merger Effective Time, Colonial shall purchase, and MAA shall cause to be maintained in full force and effect (and the obligations under to be honored), during the six (6) year period beginning on the date of the Partnership Merger Effective Time, a “tail” prepaid insurance policy or policies (which policy or policies by their respective express terms shall survive the Mergers), of at least the same coverage and amounts and containing terms and conditions that are no less favorable to the directors, officers, agents or fiduciaries of Colonial or any of the Colonial Subsidiaries as Colonial’s and the Colonial Subsidiaries’ existing policy or policies, for the benefit of the current and former trustees, directors, officers, agents or fiduciaries of Colonial and each Colonial Subsidiary with a claims period of six (6) years from the Partnership Merger Effective Time with respect to directors’ and officers’ liability insurance for Claims arising from facts or events that occurred on or prior to the Partnership Merger Effective Time; provided, however, that in no event shall the aggregate premium payable for such “tail” insurance policy for its entire period exceed an amount per year of coverage equal to 300% of the current annual premium paid by Colonial for such insurance (such amount being the “Maximum Premium”). If Colonial is unable to obtain the “tail” insurance described in the first sentence of this Section 7.6(c) for an amount equal to or less than the Maximum Premium, Colonial shall be entitled to obtain as much comparable “tail” insurance as possible for an amount equal to the Maximum Premium. If Colonial is unable to purchase such “tail” insurance contemplated in the two preceding sentences, MAA shall, at Colonial’s request, purchase, and maintain in full force and effect (and honor the obligations under), during the six (6) year period beginning on the date of the Partnership Merger Effective Time, a “tail” insurance policy from one or more insurance carriers believed to be sound and reputable with respect to directors’ and officers’ liability insurance and fiduciary liability insurance of at least the same coverage and amounts and containing terms and conditions no less favorable to directors, officers, agents, or fiduciaries of Colonial or any of the Colonial Subsidiaries as Colonial or any of the Colonial Subsidiaries’ existing policy or policies for the benefit of the current and former directors, officers, agents or fiduciaries of Colonial or any Colonial Subsidiary with a claims period of six (6) years from the Partnership Merger Effective Time; provided, however, that in no event shall MAA be required to pay more than the Maximum Premium as the aggregate premium for such “tail” insurance policies for its entire period, in which case MAA will obtain as much comparable “tail” insurance as possible for an amount equal to the Maximum Premium.

(d) If any of MAA, MAA LP or any of their respective successors or assigns (i) consolidates with or merges with or into any other Person and shall not be the continuing or surviving company, partnership or other entity of such consolidation or merger or (ii) liquidates, dissolves or winds-up, or transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of MAA or MAA LP, as applicable, shall assume the obligations set forth in this Section 7.6.

(e) MAA shall pay all reasonable expenses, including reasonable attorneys’ fees, that may be incurred by any Indemnified Person in enforcing the indemnity and other obligations provided in this Section 7.6; provided, however, that such Indemnified Person provides an undertaking to repay such expenses if it is determined by a final and non-appealable judgment of a court of competent jurisdiction that such Person is not legally entitled to indemnification under Law.

(f) The provisions of this Section 7.6 are intended to be for the express benefit of, and shall be enforceable by, each Indemnified Person (who are intended to be third party beneficiaries of this Section 7.6), his or her heirs and his or her personal representatives, shall be binding on all successors and assigns of MAA and Colonial, and shall not be amended in a manner that is adverse to the Indemnified Person (including his or her successors, assigns and heirs) without the prior written consent of the Indemnified Person (including the successors, assigns and heirs) affected thereby. The exculpation and indemnification provided for by this Section 7.6 shall be in addition to, and not in substitution for, any other rights to indemnification or exculpation which an Indemnified Person is entitled, whether pursuant to applicable Law, contract or otherwise.

(g) Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to

A-72

the Colonial or any of the Colonial Subsidiaries for any of their respective trustees, directors, managers, officers or other employees, it being understood and agreed that (i) the indemnification provided for in this Section 7.6 is not prior to or in substitution for any such claims under such policies; (ii) the indemnification provided by Colonial, MAA and MAA LP under this Section 7.6 with respect to any Claim shall be specifically excess of any valid and collectible insurance available to such Persons for such Claim; and (iii) to the extent that any Indemnified Party receives any payment with respect to a Claim under any insurance maintained by Colonial, MAA or MAA LP after payment by Colonial, MAA or MAA LP of any amounts with respect to indemnification provided for in this Section 7.6, such Indemnified Party shall promptly pay the duplicative portion of such insurance payment to Colonial, MAA or MAA LP, as applicable.

Section 7.7 Appropriate Action; Consents

(a) Subject to the terms and conditions set forth in this Agreement, each of Colonial and MAA shall, and shall cause the Colonial Subsidiaries and the MAA Subsidiaries, respectively, to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Party in doing, all things necessary, proper or advisable under applicable Law or pursuant to any contract or agreement to consummate and make effective, as promptly as practicable, the Mergers and the other transactions contemplated by this Agreement, including (i) the taking of all actions necessary to cause the conditions to Closing set forth in Article VIII to be satisfied, (ii) the obtaining of all necessary actions or nonactions, waivers, consents and approvals from Persons (other than Governmental Authorities, which are addressed in Section 7.3) necessary in connection with the consummation of the Mergers and the other transactions contemplated by this Agreement and the making of all necessary registrations and filings and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Authority or other Persons necessary in connection with the consummation of the Mergers and the other transactions contemplated by this Agreement, (iii) subject to Section 7.8(e), the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the Mergers or the other transactions contemplated by this Agreement, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Authority vacated or reversed, so as to enable the Closing to occur as soon as reasonably possible, and (iv) the execution and delivery of any additional instruments necessary to consummate the Mergers and the other transactions contemplated by this Agreement and to fully carry out the purposes of this Agreement.

(b) The Colonial Parties shall give prompt notice to the MAA Parties, and the MAA Parties shall give prompt notice to the Colonial Parties, if (i) any representation or warranty made by it contained in this Agreement becomes untrue or inaccurate such that it would be reasonable to expect that the applicable closing conditions would be incapable of being satisfied by the Outside Date or (ii) it fails to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement such that it would be reasonable to expect that the applicable closing conditions would be incapable

A-73

of being satisfied by the Outside Date; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the Parties or the conditions to the obligations of the Parties under this Agreement. Without limiting the foregoing, the Colonial Parties shall give prompt notice to the MAA Parties, and the MAA Parties shall give prompt notice to the Colonial Parties, if, to the Knowledge of such Party, the occurrence of any state of facts, change, development, event or condition would cause, or would reasonably be expected to cause, any of the conditions to Closing set forth herein not to be satisfied or satisfaction to be materially delayed.

(c) Notwithstanding anything to the contrary in this Agreement, the failure by the Colonial Parties or the MAA Parties to provide notice under Section 7.8(a), Section 7.8(b) or Section 7.8(d) shall not constitute a breach of covenant for purposes of Section 8.2(b) or Section 8.3(b).

(d) Each of the Parties hereto agrees to give prompt written notice to the other Parties upon becoming aware of the occurrence or impending occurrence of any event or circumstance relating to it or any of the other Colonial Subsidiaries or the other MAA Subsidiaries, respectively, which could reasonably be expected to have, individually or in the aggregate, a Colonial Material Adverse Effect or a MAA Material Adverse Effect, as the case may be.

(e) The Colonial Parties shall give prompt notice to the MAA Parties, and the MAA Parties shall give prompt notice to the Colonial Parties, of any Action commenced or, to such Party’s Knowledge, threatened against, relating to or involving such Party or any of the other Colonial Subsidiaries or the other MAA Subsidiaries, respectively, which relates to this Agreement, the Mergers or the other transactions contemplated by this Agreement. The Colonial Parties shall give the MAA Parties the opportunity to reasonably participate in the defense and settlement of any litigation against the Colonial Parties and/or their trustees relating to this Agreement and the transactions contemplated hereby, and no such settlement shall be agreed to without MAA’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed).

Agreement under this Section 9.1(h) shall not be available to MAA where a failure to obtain the MAA Partner Approval was primarily caused by any action or failure to act of a MAA Party that constitutes a material breach of this Agreement.

Section 9.2 Effect of Termination.

(a) In the event that this Agreement is terminated pursuant to Section 9.1, written notice thereof shall be given to the other Party or Parties, specifying the provisions hereof pursuant to which such termination is made and describing the basis therefor in reasonable detail, and subject to compliance with Section 9.3, this Agreement shall forthwith become null and void and of no further force or effect whatsoever without liability on the part of any Party hereto, and all rights and obligations of any Party hereto shall cease; provided, however, that, notwithstanding anything in the foregoing to the contrary (a) no such termination shall relieve any Party hereto of any liability or damages resulting from or arising out of fraud or any intentional breach of this Agreement; and (b) the Confidentiality Agreement, Section 7.2(b), this Section 9.2, Section 9.3, Article X (other than Section 10.1) and the definitions of all defined terms appearing in such sections shall survive any termination of this Agreement pursuant to Section 9.1.

(i) by either MAA or Colonial pursuant to Section 9.1(c), Section 9.1(e) or Section 9.1(h), or by Colonial pursuant to Section 9.1(d), and MAA (x) receives or has received a bona fide Acquisition Proposal with respect to MAA after the date of this Agreement, which proposal has been publicly announced prior to the date of the MAA Shareholder Meeting (with respect to a termination under Section 9.1(e) or Section 9.1(h)) or prior to the termination of this Agreement (with respect to a termination under Section 9.1(c) or Section 9.1(d)), and (y) within twelve (12) months of the termination of this Agreement, consummates a transaction regarding, or executes a definitive agreement which is later consummated with respect to, an Acquisition Proposal, then MAA shall pay, or cause to be paid, to Colonial a fee equal to the Termination Fee plus, if not previously paid pursuant to Section 9.3(a)(iv) below, the Expense Amount, by wire transfer of same day funds to an account designated by Colonial, not later than the consummation of such transaction arising from such Acquisition Proposal; provided, however, that for purposes of this Section 9.3(a)(i), the references to “twenty percent (20%)” in the definition of Acquisition Proposal shall be deemed to be references to “fifty percent (50%)”;

A-83

Partner Approval shall not have been obtained, or by Colonial pursuant to Section 9.1(d), then MAA shall pay, or cause to be paid, to Colonial the Expense Amount (by wire transfer to an account designated by Colonial) within two (2) Business Days of such termination;

(iv) by either MAA or Colonial pursuant to Section 9.1(e) because the Colonial Shareholder Approval shall not have been obtained, or by MAA pursuant to Section 9.1(d), then Colonial shall pay, or cause to be paid, to MAA the Expense Amount (by wire transfer to an account designated by MAA) within two (2) Business Days of such termination;

(b) Notwithstanding anything to the contrary set forth in this Agreement, the Parties agree that:

(i) under no circumstances shall MAA or Colonial be required to pay the Termination Fee and the Expense Amount on more than one occasion; and

(ii) neither MAA nor Colonial shall be required to pay any amount in excess of the sum of the Termination Fee and the Expense Amount, except as set forth in Section 9.3(c) or in the case of such Party’s fraud or intentional breach of this Agreement.

(c) Each of the Parties hereto acknowledges that (i) the agreements contained in this Section 9.3 are an integral part of the transactions contemplated by this Agreement, (ii) neither the Termination Fee nor the Expense Amount is a penalty, and (iii) without these agreements, the Parties would not enter into this Agreement; accordingly, if MAA or Colonial, as the case may be, fails to timely pay any amount due pursuant to this Section 9.3 and, in order to obtain such payment, either MAA or Colonial, as the case may be, commences a suit that results in a judgment against the other Party for the payment of any amount set forth in this Section 9.3, such paying Party shall pay the other Party its costs and Expenses in connection with such suit, together with interest on such amount at the annual rate of the prime rate of Citibank, N.A. in effect on the date of payment for the period from the date such payment was required to be made through the date such payment was actually received, or such lesser rate as is the maximum permitted by applicable Law

In the event that the Fee Payor is obligated to pay the Fee

A-84

Payee the Expense Amount and/or Termination Fee, as applicable, the amount payable to the Fee Payee in any tax year of the Fee Payee shall not exceed the lesser of (i) the Expense Amount and/or Termination Fee, as applicable, of the Fee Payee, and (ii) the sum of (A) the maximum amount that can be paid to the Fee Payee without causing the Fee Payee to fail to meet the requirements of Section 856(c)(2) and (3) of the Code for the relevant tax year, determined as if the payment of such amount did not constitute income described in Sections 856(c)(2) or 856(c)(3) of the Code (“Qualifying Income”) and the Fee Payee has income from unknown sources during such year in an amount equal to 1% of its gross income which is not Qualifying Income (in addition to any known or anticipated income which is not Qualifying Income), in each case, as determined by the Fee Payee’s independent accountants, plus (B) in the event the Fee Payee receives either (x) a letter from the Fee Payee’s counsel indicating that the Fee Payee has received a ruling from the IRS as described below in this Section 9.3(d) or (y) an opinion from the Fee Payee’s outside counsel as described below in this Section 9.3(d), an amount equal to the excess of the Expense Amount and/or the Termination Fee, as applicable, less the total amount paid under clause (A) above.

(ii) To secure the Fee Payor’s obligation to pay these amounts, the Fee Payor shall deposit into escrow an amount in cash equal to the Expense Amount or the Termination Fee, as applicable, with an escrow agent selected by the Fee Payor on such terms (subject to this Section 9.3(d)) as shall be mutually agreed upon by the Fee Payor, the Fee Payee and the escrow agent. The payment or deposit into escrow of the Expense Amount or the Termination Fee, as applicable, pursuant to this Section 9.3(d) shall be made at the time the Fee Payor is obligated to pay the Fee Payee such amount pursuant to Section 9.3 by wire transfer. The escrow agreement shall provide that the Expense Amount or the Termination Fee, as applicable, in escrow or any portion thereof shall not be released to the Fee Payee unless the escrow agent receives any one or combination of the following: (i) a letter from the Fee Payee’s independent accountants indicating the maximum amount that can be paid by the escrow agent to the Fee Payee without causing the Fee Payee to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if the payment of such amount did not constitute Qualifying Income and the Fee Payee has income from unknown sources during such year in an amount equal to 1% of its gross income which is not Qualifying Income (in addition to any known or anticipated income which is not Qualifying Income), in which case the escrow agent shall release such amount to the Fee Payee, or (ii) a letter from the Fee Payee’s counsel indicating that (A) the Fee Payee received a ruling from the IRS holding that the receipt by the Fee Payee of the Expense Amount and/or Termination Fee, as applicable, would either constitute Qualifying Income or would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code or (B) the Fee Payee’s outside counsel has rendered a legal opinion to the effect that the receipt by the Fee Payee of the Expense Amount and/or the Termination Fee, as applicable, should either constitute Qualifying Income or should be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code, in which case the escrow agent shall release the remainder of the Expense Amount and/or the Termination Fee, as applicable, to the Fee Payee. The Fee Payor agrees to amend this Section 9.3(d) at the reasonable request of the Fee Payee in order to (i) maximize the portion of the Expense Amount and/or the Termination Fee, as applicable, that may be distributed to the Fee Payee hereunder without causing the Fee Payee to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, (ii) improve the Fee Payee’s chances of securing a favorable ruling described in this Section 9.3(d) or (iii) assist the Fee Payee in obtaining a favorable legal opinion from its outside counsel as described in this Section 9.3(d). Any amount of the Expense Amount and/or the Termination Fee, as applicable, that remains unpaid as of the end of a taxable year shall be paid as soon as possible during the following taxable year, subject to the foregoing limitations of this Section 9.3(d), provided, that the obligation of the Fee Payor to pay the unpaid portion of the Expense Amount and/or the Termination Fee, as applicable, shall terminate on the December 31 following the date which is five (5) years from the date of this Agreement. Any costs and expenses of the escrow agent shall be borne solely by the Fee Payee.

Any payment due to a Party described in Section 9.3(c) shall be subject to the same limitations on payment as set forth in this Section 9.3(d).

A-85

(e) Except as set forth in this Section 9.3, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such expenses whether or not the Mergers are consummated.

Section 9.4 Amendment. To the extent permitted by applicable Law, this Agreement may be amended by the Parties hereto, by action taken or authorized by the Colonial Board or the MAA Board, as applicable, at any time before or after approval of the matters presented in connection with the Mergers by the shareholders of MAA, shareholders of Colonial or holders of MAA OP Units, but, after any such approval, no amendment shall be made which by Law requires further approval by such shareholders or holders without such further approval by such shareholders or holders. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties hereto.

Section 9.5 Extension; Waiver. At any time prior to the Partnership Merger Effective Time, the Parties hereto, by action taken or authorized by the Colonial Board or the MAA Board, as applicable, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other Party hereto, (b) waive any inaccuracies in the representations and warranties of the other Party contained herein or in any document delivered pursuant hereto, and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. The failure of a Party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights. No single or partial exercise of any right, remedy, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. Any waiver shall be effective only in the specific instance and for the specific purpose for which given and shall not constitute a waiver to any subsequent or other exercise of any right, remedy, power or privilege hereunder.

Section 10.3 Counterparts. This Agreement may be executed in counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to each other Party (including by means of electronic delivery), it being understood that the Parties need not sign the same counterpart. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”), or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Section 10.4 Entire Agreement; No Third-Party Beneficiaries. This Agreement (including the schedules, documents and the instruments referred to herein) constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof, other than the Confidentiality Agreement, which shall survive the execution and delivery of this Agreement. Nothing in this Agreement, express or implied, is intended to or shall confer upon any person (other than the Parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement except for (i) the rights, benefits and remedies granted to the Indemnified Parties under Section 7.6, (ii) after the Partnership Merger Effective Time, the rights of the holders of MAA OP Units to receive the consideration set forth in Article III in accordance with the provisions of this Agreement; (iii) after the Parent Merger Effective Time, the rights of the holders of Colonial Common Shares to receive the Merger Consideration, and the rights of holders of Colonial Options and Colonial Restricted Share Awards to receive the consideration specified in Article III in accordance with the provisions of this Agreement, and (iv) the right of Colonial and MAA, on behalf of its respective shareholders, to pursue claims for damages and other relief, including equitable relief, for the other Parties’ intentional breach of this Agreement, to the extent recovery is otherwise permitted under Section 9.2. The representations and warranties in this Agreement may represent an allocation among the Parties of risks associated with particular matters regardless of the knowledge of any of the Parties. Accordingly, Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 10.5 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability and, unless the effect of such invalidity or unenforceability would prevent the Parties from realizing the major portion of the economic benefits of the Mergers that they currently anticipate obtaining therefrom, shall not render invalid or unenforceable the remaining terms and provisions of this Agreement or affect the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

Section 10.6 Assignment. Neither this Agreement nor any of the rights, interests or obligations of the Parties hereunder shall be assigned by any of the Parties hereto (whether by operation of law or otherwise) without the prior written consent of the other Parties, and any attempt to make any such assignment without such consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

Section 10.7 Governing Law. This Agreement and all claims or causes of actions (whether at Law, in contract or in tort) that may be based upon, arise out of or related to this Agreement or the negotiation, execution or performance of this Agreement shall be governed by and construed in accordance with the laws of the State of Delaware applicable to agreements entered into and performed entirely therein by residents thereof, without regard to any provisions relating to choice of laws among different jurisdictions, except that (i) the laws of the State of Alabama (including the provisions of the AREITL and the ABNEC applicable to the Parent Merger) will apply to the Parent Merger and to the discharge of the fiduciary duties of the Colonial Board or any committee thereof in connection herewith, and (ii) the laws of the State of Tennessee (including the provisions of the TBCA

A-88

applicable to the Parent Merger) will apply to the Parent Merger and the Partnership Merger and to the discharge of the fiduciary duties of the MAA Board or any committee thereof in connection herewith.

Section 10.8 Specific Performance; Venue. The Parties agree that irreparable damage would occur if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that, prior to the termination of this Agreement pursuant to Article IX, the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any federal court within the State of Delaware), and each Party hereto hereby waives any requirement for the securing or posting of any bond in connection with such remedy, this being in addition to any other remedy to which they are entitled at Law or in equity. Each of the Parties irrevocably agrees that any legal action or proceeding arising out of or relating to this Agreement brought by any other Party or its successors or assigns shall be brought and determined in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (unless the Delaware Court of Chancery shall decline to accept jurisdiction over a particular matter, in which case, in any federal court within the State of Delaware), and each of the Parties hereby irrevocably submits to the exclusive jurisdiction of the aforesaid courts for itself and with respect to its property, generally and unconditionally, with regard to any such action or proceeding arising out of or relating to this Agreement and the transactions contemplated hereby. Each of the Parties agrees not to commence any action, suit or proceeding relating thereto except in the courts described above in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each of the Parties further agrees that notice as provided herein shall constitute sufficient service of process and the Parties further waive any argument that such service is insufficient. Each of the Parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the suit, action or proceeding in any such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper, or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts.

Section 10.9 WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT, BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 10.9.

Section 10.10 Authorship. The Parties agree that the terms and language of this Agreement are the result of negotiations between the Parties and their respective advisors and, as a result, there shall be no presumption that any ambiguities in this Agreement shall be resolved against any Party.

4. Effects of Merger on Colonial Common Shares. At the Parent Merger Effective Time and by virtue of the Parent Merger and without any further action on the part of MAA, Colonial, or the holders of any securities of MAA or Colonial:

(a) Cancellation of Certain Colonial Common Shares. Each Colonial Common Share issued and outstanding immediately prior to the Parent Merger Effective Time that is held by MAA, any MAA Subsidiary or any wholly owned Colonial Subsidiary shall no longer be outstanding and shall automatically be retired and shall cease to exist, and no payment shall be made with respect thereto.

(b) Conversion of Certain Colonial Common Shares.

(c) Dissenting Shares. Notwithstanding anything herein to the contrary, Colonial Common Shares that are outstanding immediately prior to the Parent Merger Effective Time and that are held by any Person who is entitled to dissent and properly perfects such Person’s dissenters’ rights of appraisal with respect to such Colonial

B-2

Common Shares (the “Dissenting Shares”) pursuant to, and who complies in all respects with, Section 10A-2-13.01 et. seq. of the ABNEC shall not be converted into shares of MAA Common Stock as provided in Section 4(b), but rather the holders of Dissenting Shares shall be entitled to payment by MAA of the fair value (as provided in Section 10A-2-13.01 et. seq. of the ABNEC (“ABNEC Article 13”)) of such Dissenting Shares in accordance with ABNEC Article 13; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to dissent under ABNEC Article 13, then the right of such holder to be paid the fair value of such holder’s Dissenting Shares shall cease and such Dissenting Shares shall be deemed to have been converted as of the Parent Merger Effective Time into, and shall have become exchangeable solely for the right to receive, shares of MAA Common Stock as provided in Section 4(b).

(d) Fractional Colonial Common Shares. No certificate or scrip representing fractional shares of MAA Common Stock shall be issued upon the surrender for exchange of certificates or the transfer of book-entry shares registered in the transfer books of Colonial, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of MAA. Notwithstanding any other provision herein, each holder of Colonial Common Shares converted pursuant to the Parent Merger who would otherwise have been entitled to receive a fraction of a share of MAA Common Stock shall receive, in lieu thereof, cash, without interest, in an amount equal to such fractional part of a share of MAA Common Stock multiplied by the volume weighted average price of MAA Common Stock for the ten (10) trading days immediately prior to the Closing Date, starting with the opening of trading on the first trading day to the closing of the second to last trading day prior to the Closing Date, as reported by Bloomberg (the “Fractional Share Consideration”).

(e) Conversion of Restricted Colonial Common Shares. Any and all Colonial Common Shares subject to Colonial Restricted Share Awards that are converted into the right to receive MAA Common Stock pursuant to Section 4(b) shall be converted into the right to receive shares of MAA Common Stock that are subject to the same vesting and forfeiture conditions and other terms and conditions as are applicable to the Colonial Restricted Share Award immediately prior to the Parent Merger Effective Time.

(f) Conversion of Colonial Options. Each outstanding Colonial Option, whether or not exercisable at the Parent Merger Effective Time, shall be assumed by MAA by virtue of the Parent Merger and without any action on the part of the holder thereof. Subject to, and in accordance with, the terms of the applicable Colonial Equity Incentive Plan and award agreement or other agreement or other document evidencing Colonial Options, from and after the Parent Merger Effective Time, each Colonial Option so assumed by MAA pursuant to the Parent Merger will otherwise continue to have, and be subject to, the same terms and conditions (including vesting schedule) as were applicable to the corresponding Colonial Option immediately prior to the Parent Merger Effective Time as set forth in the applicable Colonial Equity Incentive Plan (including any applicable award agreement, other agreement or other document evidencing such Colonial Option) immediately prior to the Parent Merger Effective Time, except that, from and after the Parent Merger Effective Time, (A) each Colonial Option, when exercisable, will be exercisable for that number of whole shares of MAA Common Stock equal to the product of the number of Colonial Common Shares that were subject to such Colonial Option immediately prior to the Parent Merger Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of MAA Common Stock and (B) the per share exercise price for the shares of MAA Common Stock issuable upon exercise of such assumed Colonial Option will be equal to the quotient determined by dividing the exercise price of each Colonial Common Share subject to such assumed Colonial Option by the Exchange Ratio, rounded up to the nearest whole cent.

(g) Adjustments. If at any time during the period between the date of this Plan of Merger and the effective time of the Partnership Merger (the “Partnership Merger Effective Time”), Colonial should split, combine or otherwise reclassify the Colonial Common Shares, or make a dividend or other distribution in Colonial Common Shares (including any dividend or other distribution of securities convertible into Colonial Common Shares), or engage in a reclassification, reorganization, recapitalization or exchange or other like change, then (without limiting any other rights of the other Parties hereunder), the Exchange Ratio shall be ratably adjusted to reflect fully the effect of any such change. If at any time during the period between the date of this Plan of Merger and

B-3

the Partnership Merger Effective Time, MAA should split, combine or otherwise reclassify the MAA Common Stock, or make a distribution in shares of MAA Common Stock (including any dividend or other distribution of securities convertible into MAA Common Stock), or engage in a reclassification, reorganization, recapitalization or exchange or other like change (without limiting any other rights of the other Parties hereunder), then the Exchange Ratio shall be ratably adjusted to reflect any such change.

(h) Withholding Rights. The Parties, Colonial LP, MAA LP, the respective affiliates of the foregoing and the bank or trust company appointed by MAA to act as exchange agent for the payment and delivery of the Merger Consideration and the Fractional Share Consideration, as applicable, shall be entitled to deduct and withhold from the Merger Consideration and Fractional Share Consideration (and any other consideration otherwise payable pursuant to this Plan of Merger or deemed paid for tax purposes), such amounts as it is required to deduct and withhold with respect to such payments under the Internal Revenue Code of 1986, as amended, or any other provision of state, local or foreign law. Any such amounts so deducted and withheld shall be paid over to the applicable governmental authority in accordance with applicable law and shall be treated for all purposes of this Plan of Merger as having been paid to the person in respect of which such deduction and withholding was made.

(i) Governing Documents. The charter and bylaws of MAA as in effect immediately prior to the Parent Merger Effective Time shall be the charter and bylaws of MAA immediately following the Parent Merger Effective Time, until further amended in accordance with applicable law.

(j) Termination; Abandonment. At any time prior to the Parent Merger Effective Time, this Plan of Merger may be terminated or abandoned by the Board of Directors of MAA or the Board of Trustees of Colonial. In the event of such termination or abandonment, this Plan of Merger shall become void and neither MAA nor Colonial nor their respective shareholders, trustees, directors or officers shall be liable in respect to such termination or abandonment.

5. Effects of Merger on MAA Common Stock. The presently outstanding MAA Common Stock shall remain outstanding, and the present holders of the MAA Common Stock shall retain their present rights therein.

6. Counterparts. This Plan of Merger may be executed in counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to each other Party, it being understood that the Parties need not sign the same counterpart.

7. No Third Party Beneficiaries. Nothing in this Plan of Merger, express or implied, is intended to or shall confer upon any person (other than the Parties hereto) any right, benefit or remedy of any nature whatsoever under or by reason of this Plan of Merger except for, after the Parent Merger Effective Time, the rights of the holders of Colonial Common Shares to receive the Merger Consideration, and the rights of holders of Colonial Options and Colonial Restricted Share Awards to receive the consideration specified in Section 4 in accordance with the provisions of this Plan of Merger.

8. Effect on Merger Agreement. This Plan of Merger is intended to be the plan of merger for the Parent Merger as required by the ABNEC, AREITL and TBCA and has been executed pursuant to and in accordance with the Merger Agreement for the purpose of effecting the Parent Merger in accordance with the laws of Alabama and Tennessee. The parties to the Merger Agreement shall continue to be bound by the terms and conditions of the Merger Agreement, except that if the terms of this Plan of Merger are in conflict with any of the terms of the Merger Agreement, the terms of this Plan of Merger shall govern to the extent of such conflict.

B-4

IN WITNESS WHEREOF, MAA and Colonial have caused this Plan of Merger to be signed by their respective officers thereunto duly authorized, all as of the date first set forth above.

“Expiration Date” shall mean the earlier to occur of (i) the later of (A) the approval and adoption of the Merger Agreement at the MAA Shareholder Meeting and (B) the approval of the Merger Agreement by the

ADMINISTRATION OF PLAN; ADMINISTRATOR AUTHORITY TO SELECT PARTICIPANTS AND DETERMINE AWARDS

(b) Powers of Administrator. The Administrator shall have the power and authority to grant Awards consistent with the terms of the Plan, including the power and authority:

(i) to select the individuals to whom Awards may from time to time be granted;

(ii) to determine the time or times of grant, and the extent, if any, of Incentive Stock Options, Non-Qualified Stock Options, Restricted Stock Awards, Restricted Stock Units, Unrestricted Stock Awards, Performance Share Awards, Dividend Equivalent Rights and Other Stock-Based Awards, or any combination of the foregoing, granted to any one or more participants;

(iii) to determine the number of shares of Stock to be covered by any Award;

(iv) to determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, which terms and conditions may differ among individual Awards and participants, and to approve the form of written instruments evidencing the Awards; provided, however, that except as otherwise provided in Section 3(b) or 3(c), the Administrator is not permitted to reduce the exercise price of Stock Options or effect repricing of Stock Options through cancellation and re-grants or cancellation in exchange for cash;

(v) to accelerate at any time the exercisability or vesting of all or any portion of any Award in circumstances involving a Change in Control or the death, disability or termination of employment of a Plan participant;

(vi) subject to the provisions of Section 5(c), to extend at any time the post-termination period in which Stock Options may be exercised;

(vii) to determine at any time whether, to what extent, and under what circumstances Stock and other amounts payable with respect to an Award shall be deferred either automatically or at the election of the

E-3

participant and whether and to what extent the Company shall pay or credit amounts constituting deemed interest (at rates determined by the Administrator) or dividends or deemed dividends on such deferrals; and

(viii) at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems advisable for the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan.

All decisions and interpretations of the Administrator shall be made in the Administrator’s sole and absolute discretion and shall be final and binding on all persons, including the Company and Plan participants.

(c) Delegation of Authority to Grant Awards. The Administrator, in its discretion, may delegate to the Chief Executive Officer of the Company all or part of the Administrator’s authority and duties with respect to Awards, including the granting thereof, to individuals who are not subject to the reporting and other provisions of Section 16 of the Act or “covered employees” within the meaning of Section 162(m) of the Code. Any such delegation by the Administrator shall include a limitation as to the amount of Awards that may be awarded during the period of the delegation and shall contain guidelines as to the determination of the exercise price of any Option, the conversion ratio or price of other Awards and the vesting criteria. The Administrator may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator’s delegate or delegates that were consistent with the terms of the Plan.

SECTION 3.

STOCK ISSUABLE UNDER THE PLAN; RECAPITALIZATIONS; MERGERS; SUBSTITUTE AWARDS

(a) Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be the sum of (i) 225,000 shares plus (ii) the shares underlying awards under the Company’s 2004 Stock Plan (the “2004 Plan”) which are forfeited, cancelled or otherwise terminated after the Effective Date, subject to adjustment as provided in this Section 3. For purposes of this limitation, the shares of Stock underlying any Awards that are forfeited, canceled, held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of Stock or otherwise terminated (other than by exercise) shall be added back to the shares of Stock available for issuance under the Plan. With respect to grants made or compensation earned under the Plan, Stock Options with respect to no more than 100,000 shares of Stock may be granted to any one individual participant during any one calendar year period. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the Company.

(b) Changes in Stock. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Stock or other securities, the Committee shall make equitable or proportionate adjustments in (i) the maximum number of shares reserved for issuance under the Plan, (ii) the number of Stock Options that can be granted to any one individual participant and the maximum number of shares that may be granted under a Performance-Based Award, (iii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iv) the repurchase price, if any, per share subject to each outstanding Restricted Stock Award, and/or (v) the price for each share subject to any then outstanding Stock Options under the Plan, without reducing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options). The Committee shall also make equitable or proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and/or the terms of outstanding Awards to take into account cash dividends declared and paid other than in the ordinary course or any other extraordinary corporate event, other than those contemplated by Section 3(c) hereof, to the

E-4

extent determined to be necessary by the Committee to avoid distortion in the value of the Awards. Notwithstanding anything to the contrary set forth in this Section 3(b), no adjustment shall be required pursuant to this Section 3(b) if the Committee determines that such action could cause an Award to fail to satisfy the conditions of any applicable exception from the requirements of Section 409A of the Code or otherwise could subject a participant to the additional tax imposed under Section 409A of the Code in respect of an outstanding Award. All adjustments made by the Committee shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Committee in its discretion may make a cash payment in lieu of fractional shares.

(c) Mergers. In contemplation of and subject to the consummation of a Sale Event, the Board, or the board of directors of any corporation assuming the obligations of the Company, may, in its discretion, take any one or more of the following actions, as to outstanding Awards: (i) provide that such Awards shall be assumed or equivalent awards shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), and/or (ii) upon written notice to the participants, provide that all Awards will terminate immediately prior to the consummation of the Sale Event. In the event that, pursuant to clause (ii) above, Awards will terminate immediately prior to the consummation of the Sale Event, all vested Awards, other than Options, shall be fully settled in cash or in kind at such appropriate consideration as determined by the Administrator in its sole discretion after taking into account the consideration payable per share of Stock pursuant to the business combination (the “Merger Price”) and all Stock Options shall be fully settled, in cash or in kind, in an amount equal to the difference between (A) the Merger Price times the number of shares of Stock subject to such outstanding Stock Options (to the extent then exercisable at prices not in excess of the Merger Price) and (B) the aggregate exercise price of all such outstanding Stock Options; provided, however, that each participant may be permitted, within a specified period determined by the Administrator prior to the consummation of the Sale Event, to exercise all outstanding Stock Options, including those that are not then exercisable, subject to the consummation of the Sale Event.

(d) Substitute Awards. The Administrator may grant Awards under the Plan in substitution for stock and stock based awards held by employees of another corporation who become employees of the Company or a Subsidiary as the result of a merger or consolidation of the employing corporation with the Company or a Subsidiary or the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The Administrator may direct that the substitute awards be granted on such terms and conditions as the Administrator considers appropriate in the circumstances. Awards granted pursuant to this Section 3(d) shall not reduce the number of shares of Stock otherwise available for issuance pursuant to the Plan under Section 3(a).

(e) Outside Director Limitation. Notwithstanding any other provision of the Plan to the contrary, the aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all awards granted to any Independent Director during any single calendar year shall not exceed $200,000.

SECTION 4.

ELIGIBILITY

Participants in the Plan will be such full or part-time officers and other employees, Independent Directors and key persons of the Company, the Operating Partnership and the Company’s other Subsidiaries who are responsible for or contribute to the management, growth or profitability of the Company, the Operating Partnership and the Company’s other Subsidiaries as are selected from time to time by the Administrator in its sole discretion.

SECTION 5.

STOCK OPTIONS

(a) Form of Stock Options. Any Stock Option granted under the Plan shall be in such form as the Administrator may from time to time approve.

E-5

Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option. No Incentive Stock Option shall be granted under the Plan after June 16, 2023.

Stock Options granted pursuant to this Section 5 shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable.

(b) Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5 shall be determined by the Administrator at the time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. If an employee owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the option price of such Incentive Stock Option shall be not less than 110 percent of the Fair Market Value on the grant date.

(c) Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Option shall be exercisable more than ten years after the date the option is granted. If an employee owns or is deemed to own (by reason of the attribution rules of Section 424(d) of the Code) more than 10 percent of the combined voting power of all classes of stock of the Company or any parent or subsidiary corporation and an Incentive Stock Option is granted to such employee, the term of such option shall be no more than five years from the date of grant.

(d) Exercisability; Rights of a Shareholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion of any Stock Option. An optionee shall have the rights of a shareholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options. In the event that on the last business day of the term of a Stock Option, other than an Incentive Stock Option (i) the exercise of the Stock Option is prohibited by applicable law or (ii) Stock may not be purchased or sold by certain employees or directors of the Company due to the “black-out period” of a Company policy or a “lock-up” agreement undertaken in connection with an issuance of securities by the Company, the term of the Stock Option shall be extended for a period of thirty (30) days following the expiration of the legal prohibition, black-out period or lock-up agreement.

(e) Method of Exercise. Stock Options may be exercised in whole or in part, by giving written notice of exercise to the Company, specifying the number of shares to be purchased. Payment of the purchase price may be made by one or more of the following methods to the extent provided in the Option Award agreement:

(i) In cash, by certified or bank check or other instrument acceptable to the Administrator;

(ii) Through the delivery (or attestation to the ownership) of shares of Stock that are not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date;

(iii) By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure; or

E-6

(iv) With respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price.

Payment instruments will be received subject to collection. The delivery of certificates representing the shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Stock Option or applicable provisions of laws. In the event an optionee chooses to pay the purchase price by previously-owned shares of Stock through the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the attested shares. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the exercise of Stock Options, such as a system using an internet website or interactive voice response, then the paperless exercise of Stock Options may be permitted through the use of such an automated system.

(f) Annual Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000. To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option.

SECTION 6.

RESTRICTED STOCK AWARDS

(a) Nature of Restricted Stock Awards. A Restricted Stock Award is an Award entitling the recipient to acquire, at par value or such other higher purchase price determined by the Administrator, shares of Stock subject to such restrictions and conditions as the Administrator may determine at the time of grant (“Restricted Stock”). Conditions may be based on continuing employment (or other business relationship) and/or achievement of pre-established performance goals and objectives. The grant of a Restricted Stock Award is contingent on the participant executing the Restricted Stock Award agreement. The terms and conditions of each such agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and participants.

(b) Rights as a Shareholder. Upon the grant of the Restricted Stock Award and payment of any applicable purchase price, a participant shall have the rights of a shareholder with respect to the voting of the Restricted Stock and receipt of dividends. Notwithstanding the foregoing, cash dividends on shares covered by the Restricted Stock Award that remain subject to risk of forfeiture due to failure to meet performance-based conditions must be retained by or repaid by the participant to the Company; provided that, to the extent provided for in the Restricted Stock Award certificate, an amount equal to such cash dividends retained or repaid by the participant may be paid to the participant upon the lapsing of the performance-based conditions with respect to such Restricted Stock Award. Unless the Administrator shall otherwise determine, (i) uncertificated Restricted Stock shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture until such Restricted Stock is vested as provided in Section 6(d) below, and (ii) certificated Restricted Stock shall remain in the possession of the Company until such Restricted Stock is vested as provided in Section 6(d) below, and the participant shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe.

(c) Restrictions. Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Restricted Stock Award agreement. If a participant’s employment (or other business relationship) with the Company and its Subsidiaries terminates for any reason, the Company shall have the right to repurchase Restricted Stock that has not vested at the time of termination at its original purchase price, from the participant or the participant’s legal representative.

E-7

(d) Vesting of Restricted Stock. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Stock and the Company’s right of repurchase or forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Stock and shall be deemed “vested.” Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 17 below, in writing after the Award agreement is issued, a participant’s rights in any shares of Restricted Stock that have not vested shall automatically terminate upon the participant’s termination of employment (or other business relationship) with the Company and its Subsidiaries and such shares shall be subject to the Company’s right of repurchase as provided in Section 6(c) above.

SECTION 7.

RESTRICTED STOCK UNITS

(a) Nature of Restricted Stock Units. An Award of Restricted Stock Units is an Award of phantom stock units to a participant, subject to restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on continuing employment (or other business relationship) and/or achievement of pre-established performance goals and objectives. The grant of a Restricted Stock Unit is contingent on the participant executing the Award agreement. The terms and conditions of each such Award agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and participants. Except in the case of Restricted Stock Units with a deferred settlement date that satisfies Section 409A of the Code, at the end of the vesting period, the Restricted Stock Unit, to the extent vested, shall be settled in the form of shares of Stock. Any payment of shares of Stock under an Award of Restricted Stock Units subject to Section 409A of the Code to a participant on account of the participant’s separation of service may not be made before the date that is six months after the date of separation from service if the participant is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code.

(b) Election to Receive Restricted Stock Units in Lieu of Compensation. The Administrator may, in its sole discretion, permit a participant to elect to receive a portion of the cash compensation or Restricted Stock Award otherwise due to such participant in the form of Restricted Stock Units. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with rules and procedures established by the Administrator. The Administrator shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate.

(c) Rights as a Shareholder. A participant shall have the rights as a shareholder only as to shares of Stock acquired by the participant upon settlement of Restricted Stock Units; provided, however, that the participant may be credited with Dividend Equivalent Rights with respect to the Restricted Stock Units, subject to the provisions of Section 13(a) and such terms and conditions as the Administrator may determine.

(d) Restrictions. A Restricted Stock Unit may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of during the deferral period.

(e) Termination. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 17 below, in writing after the Award agreement is issued, a participant’s right in all Restricted Stock Units that have not vested shall automatically terminate upon the participant’s termination of employment (or cessation of business relationship) with the Company and its Subsidiaries for any reason.

SECTION 8.

UNRESTRICTED STOCK AWARDS

Grant or Sale of Unrestricted Stock. The Administrator may, in its sole discretion, grant (or sell at par value or such other higher purchase price determined by the Administrator) an Unrestricted Stock Award to any participant pursuant to which such participant may receive shares of Stock free of any restrictions (“Unrestricted

E-8

Stock”) under the Plan. Unrestricted Stock Awards may be granted or sold as described in the preceding sentence in respect of past services or other valid consideration, or in lieu of any cash compensation due to such participant.

SECTION 9.

PERFORMANCE SHARE AWARDS

(a) Nature of Performance Share Awards. A Performance Share Award is an Award entitling the recipient to acquire shares of Stock upon the attainment of specified performance goals. The Administrator may make Performance Share Awards independent of or in connection with the granting of any other Award under the Plan. The Administrator in its sole discretion shall determine whether and to whom Performance Share Awards shall be made, the performance goals applicable under each such Award, the periods during which performance is to be measured, and all other limitations and conditions applicable to the awarded Performance Shares; provided, however, that the Administrator may rely on the performance goals and other standards applicable to other performance unit plans of the Company in setting the standards for Performance Share Awards under the Plan.

(b) Rights as a Shareholder. A participant receiving a Performance Share Award shall have the rights of a shareholder only as to shares of Stock actually received by the participant under the Plan and not with respect to shares subject to the Award but not actually received by the participant. A participant shall be entitled to receive shares of Stock under a Performance Share Award only upon satisfaction of all conditions specified in the written instrument evidencing the Performance Share Award (or in a performance plan adopted by the Administrator).

(c) Termination. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 17 below, in writing after the Award agreement is issued, a participant’s rights in all Performance Share Awards shall automatically terminate upon the participant’s termination of employment (or cessation of business relationship) with the Company and its Subsidiaries for any reason.

(d) Acceleration, Waiver, Etc. At any time prior to the participant’s termination of employment (or other business relationship) by the Company and its Subsidiaries, the Administrator may in its sole discretion accelerate, waive or, subject to Section 17, amend any or all of the goals, restrictions or conditions imposed under any Performance Share Award.

SECTION 10.

OTHER STOCK-BASED AWARDS

(a) Nature of Other Stock-Based Awards. An Other Stock-Based Award includes other Awards of Stock and other Awards that are valued in whole or in part by reference to, or are otherwise based on, Stock, including without limitation, convertible preferred stock, convertible debentures, exchangeable securities and Awards valued by reference to book value or subsidiary performance. An Other Stock-Based Award may be granted to any participant either along side or in addition to or in tandem with Stock Options, Restricted Stock or Deferred Stock granted under the Plan and/or cash awards made outside of the Plan. Stock (including securities convertible into Stock) issued on a bonus basis under this Section 10 may be issued for no cash consideration. Stock (including securities convertible into Stock) purchased with a purchase right awarded under this Section 10 shall be priced at least 25 percent of the Fair Market Value of the Stock on the date of grant. The grant of an Other Stock-Based Award may be subject to restrictions and conditions as the Administrator may determine at the time of grant, including conditions based on continuing employment (or other business relationship) and/or achievement of pre-established performance goals and objectives. The grant of an Other Stock-Based Award is contingent on the participant executing the Award agreement. The terms and conditions of each such agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and participants.

(b) Rights as a Shareholder. Until such time as an Other Stock-Based Award is actually paid out in shares of Stock, a participant shall have no rights as a holder of Stock.

E-9

(c) Restrictions. An Other Stock-Based Award may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Award agreement.

(d) Termination. Except as may otherwise be provided by the Administrator in the Award agreement or, subject to Section 17 below, in writing after the Award agreement is issued, a participant’s right in his Other Stock-Based Awards that have not vested shall automatically terminate upon the participant’s termination of employment (or cessation of business relationship) with the Company and its Subsidiaries for any reason.

SECTION 11.

CASH-BASED AWARDS

Grant of Cash-Based Awards. The Administrator may, in its sole discretion, grant Cash-Based Awards to any grantee in such number or amount and upon such terms, and subject to such conditions, as the Administrator shall determine at the time of grant. The Administrator shall determine the maximum duration of the Cash-Based Award, the amount of cash to which the Cash-Based Award pertains, the conditions upon which the Cash-Based Award shall become vested or payable, and such other provisions as the Administrator shall determine. Each Cash-Based Award shall specify a cash-denominated payment amount, formula or payment ranges as determined by the Administrator. Payment, if any, with respect to a Cash-Based Award shall be made in accordance with the terms of the Award and may be made in cash or in shares of Stock, as the Administrator determines.

SECTION 12.

PERFORMANCE-BASED AWARDS TO COVERED EMPLOYEES

(a) Performance-Based Awards. Any employee or other key person providing services to the Company and who is selected by the Administrator may be granted one or more Performance-Based Awards in the form of a Restricted Stock Award, Restricted Stock Unit, Performance Share Award, Other Stock-Based Award or Cash-Based Award payable upon the attainment of Performance Goals that are established by the Administrator and relate to one or more of the Performance Criteria, in each case on a specified date or dates or over any period or periods determined by the Administrator. The Administrator shall define in an objective fashion the manner of calculating the Performance Criteria it selects to use for any Performance Period. Depending on the Performance Criteria used to establish such Performance Goals, the Performance Goals may be expressed in terms of overall Company performance or the performance of a region, division, business unit, or an individual. The Administrator, in its discretion, may adjust or modify the calculation of Performance Goals for such Performance Period in order to prevent the dilution or enlargement of the rights of an individual (i) in the event of, or in anticipation of, any unusual or extraordinary corporate item, transaction, event or development, (ii) in recognition of, or in anticipation of, any other unusual or nonrecurring events affecting the Company or the financial statements of the Company, or (iii) in response to, or in anticipation of, changes in applicable laws, regulations, accounting principles or business conditions; provided, however, that the Administrator may not exercise such discretion in a manner that would increase the Performance-Based Award granted to a Covered Employee. Each Performance-Based Award shall comply with the provisions set forth below.

(b) Grant of Performance-Based Awards. With respect to each Performance-Based Award granted to a Covered Employee, the Administrator shall select, within the first 90 days of a Performance Cycle (or, if shorter, within the maximum period allowed under Section 162(m) of the Code) the Performance Criteria for such grant, and the Performance Goals with respect to each Performance Criterion (including a threshold level of performance below which no amount will become payable with respect to such Award). Each Performance-Based Award will specify the amount payable, or the formula for determining the amount payable, upon achievement of the various applicable performance targets. The Performance Criteria established by the Administrator may be (but need not be) different for each Performance Cycle and different Performance Goals may be applicable to Performance-Based Awards to different Covered Employees.

(c) Payment of Performance-Based Awards. Following the completion of a Performance Cycle, the Administrator shall meet to review and certify in writing whether, and to what extent, the Performance Goals for the Performance Cycle have been achieved and, if so, to also calculate and certify in writing the amount of the

E-10

Performance-Based Awards earned for the Performance Cycle. The Administrator shall then determine the actual size of each Covered Employee’s Performance-Based Award, and, in doing so, may reduce or eliminate the amount of the Performance-Based Award for a Covered Employee if, in its sole judgment, such reduction or elimination is appropriate.

(d) Maximum Award Payable. The maximum Performance-Based Award payable to any one Covered Employee under the Plan for a Performance Cycle is 50,000 shares (subject to adjustment as provided in Section 3(b) hereof) or $2,500,000 in the case of a Performance-Based Award that is a Cash-Based Award.

SECTION 13.

DIVIDEND EQUIVALENT RIGHTS

(a) Dividend Equivalent Rights. A Dividend Equivalent Right is an Award entitling the recipient to receive credits based on cash dividends that would have been paid on the shares of Stock specified in the Dividend Equivalent Right (or other award to which it relates) if such shares had been issued to and held by the recipient. A Dividend Equivalent Right may be granted hereunder to any participant as a component of an Award or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in the grant. Dividend equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional shares of Stock, which may thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the date of reinvestment. Dividend Equivalent Rights may be settled in cash or shares of Stock or a combination thereof, in a single installment or installments. A Dividend Equivalent Right granted as a component of an award of Restricted Stock Units or Other Stock-Based Award with performance-based vesting or Performance Share Award shall provide that such Dividend Equivalent Right may not be exercisable or payable unless and until the performance-based conditions have been met.

(b) Interest Equivalents. Any Award under this Plan that is settled in whole or in part in cash on a deferred basis may provide in the grant for interest equivalents to be credited with respect to such cash payment. Interest equivalents may be compounded and shall be paid upon such terms and conditions as may be specified by the grant.

(c) Termination. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 17 below, in writing after the Award agreement is issued, a participant’s rights in all Dividend Equivalent Rights or interest equivalents shall automatically terminate upon the participant’s termination of employment (or cessation of business relationship) with the Company and its Subsidiaries for any reason.

SECTION 14.

TAX WITHHOLDING

(a) Payment by Participant. Each participant shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the participant for Federal income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the participant. The Company’s obligation to deliver stock certificates to any participant is subject to and conditioned on tax obligations being satisfied by the participant.

(b) Payment in Stock. Subject to approval by the Administrator, a participant may elect to have the minimum tax withholding obligation satisfied, in whole or in part, by authorizing the Company to withhold from shares of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the minimum withholding amount due.

E-11

SECTION 15.

TRANSFERABILITY OF AWARDS

(a) Transferability. Except as provided in Section 15(b) below, during a participant’s lifetime, his or her Awards shall be exercisable only by the participant, or by the participant’s legal representative or guardian in the event of the participant’s incapacity. No Awards shall be sold, assigned, transferred or otherwise encumbered or disposed of by a participant other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards shall be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void.

(b) Administrator Action. Notwithstanding Section 15(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding a given Award or by subsequent written approval that the participant (who is an employee or director) may transfer his or her Non-Qualified Options to his or her immediate Family Members for no value or consideration, provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award. In no event may an Award be transferred by a participant for value.

(c) Family Member. For purposes of Section 15(b), “Family Member” shall mean a participant’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the participant’s household (other than a tenant of the participant), a trust in which these persons (or the participant) have more than 50 percent of the beneficial interest, a foundation in which these persons (or the participant) control the management of assets, and any other entity in which these persons (or the participant) own more than 50 percent of the voting interests.

(d) Designation of Beneficiary. Each participant to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the participant’s death. Any such designation shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased participant, or if the designated beneficiaries have predeceased the participant, the beneficiary shall be the participant’s estate.

SECTION 16.

TRANSFER, LEAVE OF ABSENCE, ETC.

For purposes of the Plan, the following events shall not be deemed a termination of employment:

(a) a transfer to the employment of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another Subsidiary; or

(b) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-employment is guaranteed either by a statute or by contract or under the written policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing.

SECTION 17.

AMENDMENTS AND TERMINATION

Unless sooner terminated as herein provided, the Plan shall terminate on the tenth anniversary of the date the Plan is approved by the Administrator and no Award shall be granted under the Plan on and after such date. The termination of the Plan shall not adversely affect the rights under any outstanding Award without the holder’s written consent. The Administrator may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder’s written consent. Except as provided in Section 3(b) or 3(c), in no event may the

E-12

Administrator exercise its discretion to reduce the exercise price of outstanding Stock Options or effect repricing of Stock Options through cancellation and re-grants or cancellation in exchange for cash. Any material Plan amendments (other than amendments that curtail the scope of the Plan), including any Plan amendments that (i) increase the number of shares reserved for issuance under the Plan, (ii) expand the type of Awards available under, materially expand the eligibility to participate in, or materially extend the term of, the Plan, or (iii) materially change the method of determining Fair Market Value, shall be subject to approval by the Company shareholders entitled to vote at a meeting of shareholders. In addition, to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code or to ensure that compensation earned under Awards qualifies as performance-based compensation under Section 162(m) of the Code, Plan amendments shall be subject to approval by the Company shareholders entitled to vote at a meeting of shareholders. Nothing in this Section 17 shall limit the Board’s authority to take any action permitted pursuant to Section 3(c).

SECTION 18.

STATUS OF PLAN

Unless the Administrator shall otherwise expressly determine in writing, with respect to the portion of any Award which has not been exercised and any payments in cash, Stock or other consideration not received by a participant, a participant shall have no rights greater than those of a general creditor of the Company. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence.

SECTION 19.

SECTION 409A AWARDS

To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section 409A) to a participant who is then considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of (i) six months and one day after the participant’s separation from service, or (ii) the participant’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. Further, the settlement of any such Award may not be accelerated except to the extent permitted by Section 409A.

SECTION 20.

GENERAL PROVISIONS

(a) No Distribution; Compliance with Legal Requirements. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof.

No shares of Stock shall be issued pursuant to an Award until all applicable securities law and other legal and stock exchange or similar requirements have been satisfied. The Administrator may require the placing of such stop-orders and restrictive legends on certificates for Stock and Awards as it deems appropriate.

(b) Delivery of Stock Certificates. Stock certificates to be delivered to participants under this Plan shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the participant, at the participant’s last known address on file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the Company shall have given to the participant by electronic mail (with proof of receipt) or by United States mail, addressed to the participant, at the participant’s last known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry”

E-13

records). Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates evidencing shares of Stock pursuant to the exercise of any Award, unless and until the Board has determined, with advice of counsel (to the extent the Board deems such advice necessary or advisable), that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed, quoted or traded. All Stock certificates delivered pursuant to the Plan shall be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with federal, state or foreign jurisdiction, securities or other laws, rules and quotation system on which the Stock is listed, quoted or traded. The Administrator may place legends on any Stock certificate to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Board may require that an individual make such reasonable covenants, agreements, and representations as the Board, in its discretion, deems necessary or advisable in order to comply with any such laws, regulations, or requirements. The Administrator shall have the right to require any individual to comply with any timing or other restrictions with respect to the settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator.

(c) Shareholder Rights. Until Stock is deemed delivered in accordance with Section 20(b), no right to vote or receive dividends or any other rights of a shareholder will exist with respect to shares of Stock to be issued in connection with an Award, notwithstanding the exercise of a Stock Option or any other action by the participant with respect to an Award.

(d) Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of Awards shall not confer upon any employee any right to continued employment with the Company or any Subsidiary and shall not interfere in any way with the right of the Company or any Subsidiary to terminate the employment of any of its employees at any time.

(e) Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to such Company insider-trading-policy-related restrictions, terms and conditions as may be established by the Administrator, or in accordance with policies set by the Administrator, from time to time.

(f) Forfeiture of Awards under Sarbanes-Oxley Act. If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under the securities laws, then any participant who is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002 shall reimburse the Company for the amount of any Award received by such individual under the Plan during the 12-month period following the first public issuance or filing with the United States Securities and Exchange Commission, as the case may be, of the financial document embodying such financial reporting requirement.

SECTION 21.

EFFECTIVE DATE OF PLAN

This Plan shall become effective upon shareholder approval in accordance with Tennessee law, the Company’s amended and restated charter and bylaws and applicable stock exchange rules. No grants of Awards may be made hereunder after the tenth anniversary of the Effective Date.

SECTION 22.

GOVERNING LAW

This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the laws of the State of Tennessee, applied without regard to conflict of law principles.

The Board of Directors

Mid-America Apartment Communities, Inc.

6584 Poplar Avenue

Memphis, TN 38138

Members of the Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to Mid-America Apartment Communities, Inc. (the “Company”) of the Exchange Ratio (as defined below) in the proposed merger (the “Transaction”) of the Company with Colonial Properties Trust (the “Merger Partner”). Pursuant to the Agreement and Plan of Merger (the “Agreement”), among the Company, Mid-America Apartments, L.P. (the “Company L.P.”), a subsidiary of the Company L.P. (the “Merger Sub”), the Merger Partner and Colonial Realty Limited Partnership (the “Merger Partner L.P.”), among other things, (i) the Merger Sub will merge with and into the Merger Partner L.P., with the Merger Partner L.P. continuing as the surviving entity and a wholly owned subsidiary of the Company L.P. (the “Partnership Merger”), and (ii) the Merger Partner will merge with and into the Company, with the Company continuing as the surviving entity, and each outstanding share of common stock, par value $0.01 per share, of the Merger Partner (the “Merger Partner Common Stock”), other than shares of Merger Partner Common Stock owned by the Company and its subsidiaries or a subsidiary of Merger Partner and Dissenting Shares (as defined in the Agreement), will be converted into the right to receive 0.360 shares (the “Exchange Ratio”) of the Company’s common stock, par value $0.01 per share (the “Company Common Stock”).

In connection with preparing our opinion, we have (i) reviewed a draft dated May 31, 2013 of the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Merger Partner and the Company and the industries in which they operate; (iii) compared the financial and operating performance of the Merger Partner and the Company with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical market prices of the Merger Partner Common Stock and the Company Common Stock and certain publicly traded securities of such other companies; (iv) reviewed certain internal financial analyses and forecasts prepared by the management of the Company relating to their respective businesses, as well as the estimated amount and timing of the cost savings and related expenses and synergies expected to result from the Transaction (the “Synergies”); and (v) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.

In addition, we have held discussions with certain members of the management of the Merger Partner and the Company with respect to certain aspects of the Transaction, and the past and current business operations of the Merger Partner and the Company, the financial condition and future prospects and operations of the Merger Partner and the Company, the effects of the Transaction on the financial condition and future prospects of the Company, and certain other matters we believed necessary or appropriate to our inquiry.

In giving our opinion, we have relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Merger Partner and the Company or otherwise reviewed by or for us, and we have not independently verified (nor have we assumed responsibility or liability for independently verifying) any such information or its accuracy or completeness. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Merger Partner or the Company under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to us or derived therefrom,

F-1

including the Synergies, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of the Merger Partner and the Company to which such analyses or forecasts relate. We express no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. We have also assumed for United States federal income tax purposes that the Partnership Merger shall qualify as and constitute a tax-free “assets-over” form of merger governed by Treasury Regulations Section 1.708-1(c)(3)(i) and the Transaction will qualify as a tax-free reorganization, and in each case will be consummated as described in the Agreement, and that the definitive Agreement will not differ in any material respect from the draft thereof furnished to us. We have also assumed that the representations and warranties made by the Company and the Merger Partner in the Agreement and the related agreements are and will be true and correct in all respects material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues. We have further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Merger Partner or the Company or on the contemplated benefits of the Transaction.

Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. Our opinion is limited to the fairness, from a financial point of view, to the Company of the Exchange Ratio in the proposed Transaction and we express no opinion as to the fairness of the Exchange Ratio to the holders of any class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Transaction. Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Transaction, or any class of such persons relative to the Exchange Ratio in the Transaction or with respect to the fairness of any such compensation. We are expressing no opinion herein as to the price at which the Merger Partner Common Stock or the Company Common Stock will trade at any future time.

We have acted as financial advisor to the Company with respect to the proposed Transaction and will receive a fee from the Company for our services, a substantial portion of which will become payable only if the proposed Transaction is consummated. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. Please be advised that during the two years preceding the date of this letter, neither we nor our affiliates have had any other material financial advisory or other material commercial or investment banking relationships with the Merger Partner. During the two years preceding the date of this letter, we and our affiliates have had commercial or investment banking relationships with the Company. Such services during such period have included acting as co-lead arranger on the Company’s term loan credit facility in March of 2012 and acting as joint bookrunner on the Company’s equity offering in March of 2013. In addition, our commercial banking affiliate is an agent bank and a lender under outstanding credit facilities of the Company, for which it receives customary compensation or other financial benefits. In the ordinary course of our businesses, we and our affiliates may actively trade the debt and equity securities of the Company or the Merger Partner for our own account or for the accounts of customers and, accordingly, we may at any time hold long or short positions in such securities.

On the basis of and subject to the foregoing, it is our opinion as of the date hereof that the Exchange Ratio in the proposed Transaction is fair, from a financial point of view, to the Company.

June 2, 2013

The Board of Trustees

Colonial Properties Trust

2101 Sixth Avenue North, Suite 750

Birmingham, Alabama 35203

The Board of Trustees:

We understand that Colonial Properties Trust (“Colonial”) proposes to enter into an Agreement and Plan of Merger (the “Agreement”) among Mid-America Apartment Communities, Inc. (“Mid-America”), Mid-America Apartments, L.P. (“Mid-America LP”), Martha Merger Sub, L.P., a subsidiary of Mid-America LP (“OP Merger Sub”), Colonial and Colonial Realty Limited Partnership (“Colonial LP”) pursuant to which, among other things, Colonial will merge with and into Mid-America (the “Merger”) and each outstanding share of the common stock, par value $0.01 per share, of Colonial (“Colonial Common Stock”) will be converted into the right to receive 0.360 (the “Exchange Ratio”) of a share of the common stock, par value $0.01 per share, of Mid-America (“Mid-America Common Stock”). The Agreement also provides for the merger of OP Merger Sub and Colonial LP (the “Partnership Merger” and, together with the Merger, the “Transaction”). The terms and conditions of the Transaction are more fully set forth in the Agreement.

You have requested our opinion as to the fairness, from a financial point of view, to the holders of Colonial Common Stock of the Exchange Ratio provided for in the Merger pursuant to the Agreement.

In connection with this opinion, we have, among other things:

(i)

reviewed certain publicly available business and financial information relating to Colonial and Mid-America;

(ii)

reviewed certain internal financial and operating information with respect to the business, operations and prospects of Colonial furnished to or discussed with us by the management of Colonial, including certain financial forecasts relating to Colonial prepared by such management (such forecasts, the “Colonial Forecasts”);

(iii)

reviewed certain internal financial and operating information with respect to the business, operations and prospects of Mid-America furnished to or discussed with us by the management of Mid-America, including certain financial forecasts relating to Mid-America prepared by such management (such forecasts, the “Mid-America Forecasts”);

(iv)

reviewed certain estimates as to the amount and timing of cost savings (the “Cost Savings”) anticipated by the managements of Colonial and Mid-America to result from the Transaction;

(v)

discussed with the management of Colonial and Mid-America the past and current business, operations, financial condition and prospects of Colonial and Mid-America;

(vi)

reviewed the potential pro forma financial impact of the Transaction on the future financial performance of Mid-America after taking into account potential Cost Savings, including the potential effect on Mid-America’s estimated funds from operations and adjusted funds from operations;

(vii)

reviewed the trading histories for Colonial Common Stock and Mid-America Common Stock and a comparison of such trading histories with each other and with the trading histories of other companies we deemed relevant;

G-1

(viii)

compared certain financial and stock market information of Colonial and Mid-America with similar information of other companies we deemed relevant;

(ix)

compared certain financial terms of the Transaction to financial terms, to the extent publicly available, of other transactions we deemed relevant;

(x)

reviewed the relative financial contributions of Colonial and Mid-America to the future financial performance of the combined company on a pro forma basis;

(xi)

reviewed a draft dated June 2, 2013 of the Agreement (the “Draft Agreement”); and

(xii)

performed such other analyses and studies and considered such other information and factors as we deemed appropriate.

In arriving at our opinion, we have assumed and relied upon, without independent verification, the accuracy and completeness of the financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with us and have relied upon assurances of the managements of Colonial and Mid-America that they are not aware of any facts or circumstances that would make such information or data inaccurate or misleading in any material respect. With respect to the Colonial Forecasts, the Mid-America Forecasts and the Cost Savings, we have been advised by the managements of Colonial and Mid-America, and we have assumed, with the consent of Colonial, that they have been reasonably prepared on bases reflecting the best currently available estimates and good faith judgments of such managements as to the future financial performance of Colonial and Mid-America and the other matters covered thereby, and further have assumed, with the consent of Colonial, that such Cost Savings will be realized in the amounts and at the times projected. We have relied, at the direction of Colonial, upon the assessments of the managements of Colonial and Mid-America as to the ability to integrate the businesses and operations of Colonial and Mid-America.

We have not made or been provided with any independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of Colonial, Mid-America or any other entity, nor have we made any physical inspection of the properties or assets of Colonial, Mid-America or any other entity. We have not evaluated the solvency or fair value of Colonial, Mid-America or any other entity under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. We have assumed, at the direction of Colonial, that the Transaction will be consummated in accordance with its terms, without waiver, modification or amendment of any material term, condition or agreement and that, in the course of obtaining the necessary governmental, regulatory and other approvals, consents, releases and waivers for the Transaction, no delay, limitation, restriction or condition, including any divestiture requirements or amendments or modifications, will be imposed that would have an adverse effect on Colonial, Mid-America or the Transaction (including the contemplated benefits thereof) and that no such adverse effect will result in the event that the Transaction or any related transactions are effected through an alternative structure as permitted under the terms of the Agreement. We also have assumed, at the direction of Colonial, that the final executed Agreement will not differ in any material respect from the Draft Agreement reviewed by us. We further have assumed, at the direction of Colonial, that the Merger will qualify for U.S. federal income tax purposes as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended, and that the Partnership Merger will qualify as an “asset-over” form of merger under Treasury Regulations Section 1.708-1(c)(3)(i). We have been advised by Colonial and Mid-America that each of Colonial and Mid-America has operated in conformity with the requirements for qualification as a real estate investment trust (“REIT”) for U.S. federal income tax purposes since its formation as a REIT and further have assumed, at the direction of Colonial, that the Transaction will not adversely affect such status or operations of Colonial or Mid-America.

We express no view or opinion as to any terms or other aspects or implications of the Transaction (other than the Exchange Ratio to the extent expressly specified herein), including, without limitation, the form or structure of the Transaction, any terms, aspects or implications of the Partnership Merger (including any consideration payable in such Partnership Merger), any transfer of assets contemplated to be undertaken in connection with the Transaction or any other arrangements, agreements or understandings entered into in connection with or related to the Transaction or otherwise. As you are aware, we were not requested to, and we did not, solicit indications of interest or proposals from third parties regarding a possible acquisition of all or any part of Colonial or any alternative transaction; however, at Colonial’s direction, we held preliminary discussions with selected third parties that had contacted, or had been contacted by, Colonial. Our opinion is limited to the fairness, from a financial point of view, of the Exchange Ratio to the holders of Colonial Common Stock and no opinion or view is expressed with respect to any consideration received in connection with the Transaction by the holders of any class of securities, creditors or other constituencies of any party. In addition, no opinion or view is expressed with respect to the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation to any officers, directors, trustees or employees of any party to the Transaction, or class of such persons, relative to the Exchange Ratio or otherwise. Furthermore, no opinion or view is expressed as to the relative merits of the Transaction in comparison to other strategies or transactions that might be available with respect to Colonial or in which Colonial might engage or as to the underlying business decision of Colonial to proceed with or effect the Transaction. We also are not expressing any view or opinion with respect to, and have relied, with the consent of Colonial, upon the assessments of Colonial’s representatives regarding, legal, regulatory, accounting, tax and similar matters relating to Colonial, Mid-America and the Transaction (including the contemplated benefits thereof) as to which we understand that Colonial obtained such advice as it deemed necessary from qualified professionals. We further are not expressing any opinion as to what the value of Mid-America Common Stock actually will be when issued or the prices at which Colonial Common Stock or Mid-America Common Stock will trade at any time, including following announcement or consummation of the Transaction. In addition, we express no opinion or recommendation as to how any shareholder should vote or act in connection with the Transaction or any related matter.

We have acted as financial advisor to Colonial in connection with the Transaction and will receive a fee for our services, a portion of which is payable upon delivery of our opinion and the principal portion of which is contingent upon consummation of the Transaction. In addition, Colonial has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement.

We and our affiliates comprise a full service securities firm and commercial bank engaged in securities, commodities and derivatives trading, foreign exchange and other brokerage activities and principal investing as well as providing investment, corporate and private banking, asset and investment management, financing and financial advisory services and other commercial services and products to a wide range of companies, governments and individuals. In the ordinary course of our businesses, we and our affiliates may invest on a principal basis or on behalf of customers or manage funds that invest, make or hold long or short positions, finance positions or trade or otherwise effect transactions in equity, debt or other securities or financial instruments (including derivatives, bank loans or other obligations) of Colonial, Mid-America and certain of their respective affiliates.

We and our affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services to Colonial and have received or in the future may receive compensation for the rendering of these services, including (i) having acted or acting as joint lead arranger and bookrunner for, and/or as a lender under, certain letters of credit, and credit and leasing facilities of Colonial, including Colonial’s $500 million unsecured revolving credit facility due 2016, and (ii) having acted or acting as a joint sales agent in connection with certain “at-the-market” common equity offerings of Colonial.

We and our affiliates in the past have provided, currently are providing, and in the future may provide, investment banking, commercial banking and other financial services to Mid-America and have received or in the future may receive compensation for the rendering of these services, including (i) having acted or acting as a lender under certain leasing facilities of Mid-America, and (ii) having acted or acting as a joint sales agent in connection with certain “at-the-market” common equity offerings of Mid-America.

It is understood that this letter is for the benefit and use of the Board of Trustees of Colonial (in its capacity as such) in connection with and for purposes of its evaluation of the Transaction.

Our opinion is necessarily based on financial, economic, monetary, market and other conditions and circumstances as in effect on, and the information made available to us as of, the date hereof. As you are aware, the credit, financial and stock markets have been experiencing unusual volatility and we express no opinion or view as to any potential effects of such volatility on Colonial, Mid-America or the Transaction. It should be understood that subsequent developments may affect this opinion, and we do not have any obligation to update, revise or reaffirm this opinion. The issuance of this opinion was approved by our Americas Fairness Opinion Review Committee.

Based upon and subject to the foregoing, including the various assumptions and limitations set forth herein, we are of the opinion on the date hereof that the Exchange Ratio provided for in the Merger pursuant to the Agreement is fair, from a financial point of view, to the holders of Colonial Common Stock.

Very truly yours,

(1) The dissenter believes that the amount offered under Section 10A-2-13.25 is less than the fair value of his or her shares or that the interest due is incorrectly calculated;

(2) The corporation fails to make an offer under Section 10A-2-13.25 within 60 days after the date set for demanding payment; or

(3) The corporation, having failed to take the proposed action, does not release the transfer re-strictions imposed on shares within 60 days after the date set for demanding payment.

(b) A dissenter waives his or her right to demand payment under this section unless he or she no-tifies the corporation of his or her demand in writing under subsection (a) within 30 days after the corporation offered payment for his or her shares.

H-4

§ 10A-2-13.30. Court action.

(a) If a demand for payment under Section 10A-2-13.28 remains unsettled, the corporation shall commence a proceeding within 60 days after receiving the payment demand and petition the court to determine the fair value of the shares and accrued interest. If the corporation does not commence the proceeding within the 60 day period, it shall pay each dissenter whose demand remains un-settled the amount demanded.

(b) The corporation shall commence the proceeding in the circuit court of the county where the corporation’s principal office, or, if none in this state, its registered office, is located. If the cor-poration is a foreign corporation without a registered office in this state, it shall commence the proceeding in the county in this state where the registered office of the domestic corporation merged with or whose shares were acquired by the foreign corporation was located.

(c) The corporation shall make all dissenters, whether or not residents of this state, whose demands remain unsettled parties to the proceeding as in an action against their shares, and all parties must be served with a copy of the petition. Nonresidents may be served by registered or certified mail or by publication as provided under the Alabama Rules of Civil Procedure.

(d) After service is completed, the corporation shall deposit with the clerk of the court an amount sufficient to pay unsettled claims of all dissenters party to the action in an amount per share equal to its prior estimate of fair value, plus accrued interest, under Section 10A-2-13.25.

(e) The jurisdiction of the court in which the proceeding is commenced under subsection (b) is plenary and exclusive. The court may appoint one or more persons as appraisers to receive evidence and recommend decision on the question of fair value. The appraisers have the powers described in the order appointing them, or in any amendment to it. The dissenters are entitled to the same discovery rights as parties in other civil proceedings.

(f) Each dissenter made a party to the proceeding is entitled to judgment for the amount the court finds to be the fair value of his or her shares, plus accrued interest. If the court’s determination as to the fair value of a dissenter’s shares, plus accrued interest, is higher than the amount estimated by the corporation and deposited with the clerk of the court pursuant to subsection (d), the corporation shall pay the excess to the dissenting shareholder. If the court’s determination as to fair value, plus accrued interest, of a dissenter’s shares is less than the amount estimated by the corporation and deposited with the clerk of the court pursuant to subsection (d), then the clerk shall return the balance of funds deposited, less any costs under Section 10A-2-13.31, to the corporation.

(g) Upon payment of the judgment, and surrender to the corporation of the certificate or certificates representing the appraised shares, a dissenting shareholder ceases to have any interest in the shares.

§ 10A-2-13.31. Court costs and counsel fees.

(a) The court in an appraisal proceeding commenced under Section 10A-2-13.30 shall determine all costs of the proceeding, including compensation and expenses of appraisers appointed by the court. The court shall assess the costs against the corporation, except that the court may assess costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds the dissenters acted arbitrarily, vexatiously, or not in good faith in demanding payment under Section 10A-2-13.28.

(b) The court may also assess the reasonable fees and expenses of counsel and experts for the respective parties, in amounts the court finds equitable:

(1) Against the corporation and in favor of any or all dissenters if the court finds the corporation did not substantially comply with the requirements of Sections 10A-2-13.20 through 10A-2-13.28; or

(2) Against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by this chapter.

H-5

(c) If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated, and that the fees for those services should not be assessed against the corporation, the court may award to these counsel reasonable fees to be paid out of the amounts awarded the dissenters who were benefitted.

§ 10A-2-13.32. Status of shares after payment.

Shares acquired by a corporation pursuant to payment of the agreed value therefor or to payment of the judgment entered therefor, as in this chapter provided, may be held and disposed of by the corporation as in the case of other treasury shares, except that, in the case of a merger or share exchange, they may be held and disposed of as the plan of merger or share exchange may otherwise provide.

PURPOSE

Section 3.1 Purpose and Business. The purpose and nature of the business to be conducted by the Partnership is (i) to conduct any business that may be lawfully conducted by a limited partnership organized pursuant to the Act, provided, however, that such business shall be limited to and conducted in such a manner as to permit the General Partner at all times to be classified as a REIT, unless the General Partner ceases to qualify as a REIT for reasons other than the conduct of the business of the Partnership, (ii) to enter into any partnership, joint venture or other similar arrangement to engage in any of the foregoing or to own interests in any entity engaged in any of the foregoing, and (iii) to do anything necessary or incidental to the foregoing. In connection with the foregoing, and without limiting the General Partner’s right, in its sole discretion, to cease qualifying as a REIT, the Partners acknowledge the General Partner’s current status as a REIT inures to the benefit of all of the Partners and not solely to the benefit of the General Partner.

Section 3.2 Powers. The Partnership is empowered to do any and all acts and things necessary, appropriate, proper, advisable, incidental to or convenient for the furtherance and accomplishment of the purposes and business described herein and for the protection and benefit of the Partnership, provided that the Partnership shall not take any action which, in the judgment of the General Partner, in its sole and absolute discretion, (i) could adversely affect the ability of the General Partner to continue to qualify as a REIT, (ii) could subject the General Partner to any additional taxes under Section 857 or Section 4981 of the Code, or (iii) could violate any law or regulation of any governmental body or agency having jurisdiction over the General Partner or its securities, unless such action shall have been specifically consented to by the General Partner in writing.

CAPITAL CONTRIBUTIONS

Section 4.1 Capital Contributions.

A. As of the date of this Agreement, but in any event prior to the Partnership Merger Effective Time, each Partner owns that number of Class A Common Units and/or Class B Common Units as is set forth opposite such Partner’s name on Exhibit A-1 hereto and has Percentage Interests as set forth on the Partner Registry. At the Partnership Merger Effective Time (as defined below), the Partner Registry shall be read as set forth on Exhibit A-2 hereto. To the extent the Partnership acquires any property by the merger of any other Person into the Partnership, Persons who receive Partnership Interests in exchange for their interests in the Person merging into the Partnership shall become Partners and shall be deemed to have made Capital Contributions as provided in the applicable merger agreement (or, if the merger agreement does not so provided, as determined by the General Partner). The Partners shall own Partnership Units in the amounts set forth for such Partner in the Partner Registry, as may be updated from time to time, and shall have a Percentage Interest in the Partnership as set forth in the Partner Registry, which Percentage Interest shall be adjusted in the Partner Registry from time to time by the General Partner to the extent necessary to reflect accurately redemptions, Capital Contributions, the issuance of additional Partnership Units (pursuant to any merger or otherwise), or similar events having an effect on a Partner’s Percentage Interest. The Capital Contributions of the Partners shall be at all times as shown on the books and records of the General Partner. The number of Partnership Units held by the General Partner equal to one percent (1%) of all outstanding Partnership Units from time to time shall be deemed to be the general partner Common Units and shall be the General Partnership Interest. Except as provided in Section 4.2, 10.5 and 13.10, the Partners shall have no obligation to make any additional Capital Contributions or loans to the Partnership. Notwithstanding any other provision contained in this Agreement, the Partnership is authorized to take the actions and give effect to the transactions contemplated by that certain Agreement and Plan of Merger by and among Mid-America Apartment Communities, Inc., the Partnership, Martha Merger Sub, L.P., Colonial Properties Trust and Colonial Realty Limited Partnership dated on or about June 2, 2013 (the “Merger Agreement”). Without limiting the generality of the immediately preceding sentence, at the Partnership Merger Effective Time (as defined in the Merger Agreement), the Partnership shall issue Common Units in accordance

I-11

with the Merger Agreement and the recipients thereof shall be admitted as Limited Partners of the Partnership with respect to such Common Units.

Section 4.2 Issuances of Additional Partnership Interests.

A. The General Partner is hereby authorized to cause the Partnership from time to time to issue to the Partners (including the General Partner) or other Persons additional Partnership Units or other Partnership Interests in one or more classes, or one or more series of any of such classes, with such designations, preferences and relative, participating, optional or other special rights, powers and duties, including rights, powers and duties senior to Limited Partner Interests, all as shall be determined by the General Partner in its sole and absolute discretion subject to Tennessee law, including, without limitation, (i) the allocations of items of Partnership income, gain, loss, deduction and credit to each such class or series of Partnership Interests; (ii) the right of each such class or series of Partnership Interests to share in Partnership distributions; and (iii) the rights of each such class or series of Partnership Interests upon dissolution and liquidation of the Partnership; provided that no such additional Partnership Units or other Partnership Interests shall be issued to the General Partner unless either (a)(1) the additional Partnership Interests are issued in connection with an issuance of additional REIT Shares or Preferred REIT Shares of the General Partner, which shares have designations, preferences and other rights such that the economic interests attributable to such shares are substantially similar to the designations, preferences and other rights of the additional Partnership Interests issued to the General Partner in accordance with this Section 4.2A, and (2) the General Partner shall make a Capital Contribution to the Partnership in an amount equal to the net proceeds raised in connection with the issuance of such additional REIT Shares or Preferred REIT Shares of the General Partner, or (b) the additional Partnership Interests in the applicable class or series are issued to all Partners in proportion to their respective Percentage Interests in such class or series.

B. The General Partner shall not issue any additional REIT Shares or Preferred REIT Shares (other than REIT Shares issued pursuant to Section 8.6), or rights, options, warrants or convertible or exchangeable securities containing the right to subscribe for or purchase REIT Shares or Preferred REIT Shares (collectively “New Securities”) other than to all holders of REIT Shares unless (i) the General Partner shall cause the Partnership to issue to the General Partner Partnership Interests or rights, options, warrants or convertible or exchangeable securities of the Partnership having designations, preferences and other rights, all such that the economic interests are substantially similar to those of the New Securities, and (ii) the General Partner contributes the net proceeds from the issuance of such New Securities and from the exercise of rights contained in such New Securities to the Partnership. Without limiting the foregoing, the General Partner is expressly authorized to issue New Securities for less than fair market value, and the General Partner is expressly authorized to cause the Partnership to issue to the General Partner corresponding Partnership Interests, so long as (x) the General Partner concludes in good faith that such issuance is in the interests of the General Partner and the Partnership (for example, and not by way of limitation, the issuance of REIT Shares and corresponding Partnership Units pursuant to an employee stock purchase plan providing for employee purchases of REIT Shares at a discount from fair market value or employee stock options that have an exercise price that is less than the fair market value of the REIT Shares, either at the time of issuance or at the time of exercise), and (y) the General Partner contributes all proceeds from such issuance and exercise to the Partnership.

Section 4.3 Contribution of Proceeds of Issuance of REIT Shares. In connection with the issuance of REIT Shares or Preferred REIT Shares pursuant to Section 4.2, the General Partner shall contribute any net proceeds raised in connection with such issuance to the Partnership; provided that if the net proceeds actually received by the General Partner are less than the gross proceeds of such issuance as a result of any underwriter’s discount or other expenses paid or incurred in connection with such issuance, then the General Partner shall be deemed to have made a Capital Contribution to the Partnership in the amount equal to the sum of the net proceeds of such issuance plus the amount of such underwriter’s discount and other expenses paid by the General Partner.

Section 4.4 No Preemptive Rights. Except to the extent expressly granted by the Partnership pursuant to another agreement, no Person shall have any preemptive, preferential or other similar right with respect to

I-12

(i) Capital Contributions or loans to the Partnership or (ii) the issuance or sale of any Partnership Units or other Partnership Interests.

ARTICLE 5

DISTRIBUTIONS

Section 5.1 Requirement and Characterization of Distributions.

A. The General Partner shall distribute at least quarterly an amount equal to 100% of Available Cash generated by the Partnership during such quarter or shorter period to the Partners who are Partners on the Partnership Record Date with respect to such quarter or shorter period in the following order of priority:

(i) First, to the holders of Preferred Units in such amount as is required for the Partnership to pay all distributions with respect to such Preferred Units due or payable in accordance with the instruments designating such Preferred Units through the last day of such quarter or shorter period; such distributions shall be made to such Partners in such order of priority and with such preferences as have been established with respect to such Preferred Units as of the last day of such calendar quarter or shorter period; and then

(ii) To the holders of Common Units in proportion to their respective Percentage Interests in the Common Units on such Partnership Record Date;

provided that in no event may a Partner receive a distribution of Available Cash with respect to a Partnership Unit if such Partner is entitled to receive a distribution out of such Available Cash with respect to a REIT Share for which such Partnership Unit has been redeemed or exchanged. The General Partner shall take such reasonable efforts, as determined by it in its sole and absolute discretion and consistent with its qualification as a REIT, to distribute Available Cash to the Limited Partners so as to preclude any such distribution or portion thereof from being treated as part of a sale of property to the Partnership by a Limited Partner under Section 707 of the Code or the Regulations thereunder; provided that the General Partner and the Partnership shall not have liability to a Limited Partner under any circumstances as a result of any distribution to a Limited Partner being so treated.

B. Notwithstanding anything to the contrary contained herein, in no event shall a Partner receive a distribution of Available Cash with respect to any Common Unit with respect to any quarter or shorter period until such time as the Partnership has distributed to the holders of Preferred Units an amount sufficient to pay all distributions payable with respect to such Preferred Units through the last day of such quarter or shorter period, in accordance with the instruments designating such Preferred Units.

Section 5.2 Amounts Withheld. All amounts withheld pursuant to the Code or any provisions of any state or local tax law and Section 10.5 hereof with respect to any allocation, payment or distribution to the General Partner, the Limited Partners or Assignees shall be treated as amounts distributed to the General Partner, Limited Partners, or Assignees pursuant to Section 5.1 for all purposes under this Agreement.

Section 5.3 Distributions Upon Liquidation. Proceeds from a Terminating Capital Transaction and any other cash received or reductions in reserves made after commencement of the liquidation of the Partnership shall be distributed to the Partners in accordance with Section 13.2.

(ii) second, to Partners holding Preferred Units in accordance with each such Partner’s respective percentage interests in the Preferred Units determined under the respective terms of the Preferred Units (and if there are Preferred Units with different priorities in preference in distribution, then in the reverse order of their preference in distribution), until the Adjusted Capital Account (modified in the same manner as in clause (i)) of each such holder is reduced to zero;

(iii) third, to those Class A Limited Partners who are Electing Partners, in proportion to their respective Percentage Interests in Class A Common Units (provided that Net Losses shall not be allocated to a Class A Limited Partner under this Section 6.1B(iii) to the extent that such allocation would cause or increase a deficit balance in such Partner’s Adjusted Capital Account as of the end of the applicable Partnership Year and any Net Losses that cannot be allocated to a Class A Limited Partner as a result shall be allocated to those Class A Limited Partners to whom such allocation can be made without violating the limitations in this parenthetical in proportion to their Percentage Interests in Class A Common Units and thereafter in accordance with Section 6.1B(iv)); and

Except as provided in this Section 7.4 and elsewhere in this Agreement (including the provisions of Article 5 and 6 regarding distributions, payments, and allocations to which it may be entitled), the General Partner shall not be compensated for its services as general partner of the Partnership.

B. The General Partner shall be reimbursed on a monthly basis, or such other basis as the General Partner may determine in its sole and absolute discretion, for all expenses that it incurs relating to the ownership and operation of, or for the benefit of, the Partnership; provided that the amount of any such reimbursement shall be reduced by any interest earned by the General Partner with respect to bank accounts or other instruments or accounts held by it on behalf of the Partnership as permitted in Section 7.5A. The Limited Partners acknowledge that, for purposes of this Section 7.4B, all expenses of the General Partner are deemed incurred for the benefit of the Partnership. Such reimbursements shall be in addition to any reimbursement to the General Partner as a result of indemnification pursuant to Section 7.7 hereof.

C. As set forth in Section 4.3, the General Partner shall be treated as having made a Capital Contribution in the amount of all expenses that it incurs relating to any issuance of additional Partnership Interests or REIT Shares pursuant to Section 4.2 hereof.

D. In the event that the General Partner shall elect to purchase REIT Shares from its shareholders for the purpose of delivering such REIT Shares to satisfy an obligation under any dividend reinvestment program adopted by the General Partner, any employee stock purchase plan adopted by the General Partner, or any similar obligation or arrangement undertaken by the General Partner in the future, the purchase price paid by the General Partner for such REIT Shares and any other expenses incurred by the General Partner in connection with such purchase shall be considered expenses of the Partnership and shall be reimbursed to the General Partner, as the case may be, subject to the condition that: (i) if such REIT Shares subsequently are to be sold by the General Partner, the General Partner shall pay to the Partnership any proceeds received by the General Partner for such REIT Shares (provided that a transfer of REIT Shares for Units pursuant to Section 8.6 would not be considered a sale for such purposes); and (ii) if such REIT Shares are not retransferred by the General Partner within 30 days after the purchase thereof, the General Partner shall cause the Partnership to cancel a number of Class B Common Units held by the General Partner equal to the product obtained by multiplying the Conversion Factor by the number of such REIT Shares.

Section 7.5 Outside Activities of the General Partner.

A. The General Partner shall not directly or indirectly enter into or conduct any business other than in connection with the ownership, acquisition and disposition of Partnership Interests as a General Partner or Limited Partner and the management of the business of the Partnership and such activities as are incidental thereto. The General Partner shall not hold any assets other than (i) Partnership Interests as a General Partner or Limited Partner, and (ii) such bank accounts or similar instruments or accounts as it deems necessary to carry out its responsibilities contemplated under this Agreement and its organizational documents. The General Partner and any Affiliates of the General Partner may acquire Limited Partner Interests, which shall upon acquisition become Class B Common Units, and shall be entitled to exercise all rights of a Class B Limited Partner available hereunder relating to such Limited Partner Interests.

B. Except as provided in Section 7.4D, in the event the General Partner exercises its rights under Section 14 of Charter to redeem REIT Shares, then the General Partner shall cause the Partnership to purchase

I-19

from it a number of Class B Common Units equal to the number of REIT Shares redeemed by the General Partner times the Conversion Factor on the same terms and for the same aggregate price that the General Partner redeemed such REIT Shares.

Section 7.6 Contracts with Affiliates.

A. The Partnership may lend or contribute funds or other assets to its Subsidiaries or other Persons in which it has an equity investment and such Persons may borrow funds from the Partnership, on terms and conditions established in the sole and absolute discretion of the General Partner. The foregoing authority shall not create any right or benefit in favor of any Subsidiary or any other Person.

B. Except as provided in Section 7.5A, the Partnership may transfer assets to joint ventures, other partnerships, corporations or other business entities in which it is or thereby becomes a participant upon such terms and subject to such conditions consistent with this Agreement and applicable law as the General Partner, in its sole and absolute discretion, believes are advisable.

C. Except as expressly permitted by this Agreement, neither the General Partner nor any of its Affiliates shall sell, transfer or convey any property to, or purchase any property from, the Partnership, directly or indirectly, except pursuant to transactions that are determined by the General Partner in good faith to be fair and reasonable and no less favorable to the Partnership than would be obtained from an unaffiliated third party.

D. The General Partner, in its sole and absolute discretion on behalf of the Partnership and without the approval of the Limited Partners, may propose and adopt employee benefit plans, stock option plans, long term incentive plans and similar plans funded by the Partnership including, without limitation, through the issuance of one or more classes, or one or more series of any of such classes, of Partnership Interests, for the benefit of employees of the General Partner, the Partnership, Subsidiaries of the Partnership or any Affiliate of any of them in respect of services performed, directly or indirectly, for the benefit of the Partnership, the General Partner, or any of the Partnership’s Subsidiaries.

E. The General Partner is expressly authorized to enter into, in the name and on behalf of the Partnership, a right of first opportunity arrangement and other conflict avoidance agreements with various Affiliates of the Partnership and the General Partner, on such terms as the General Partner, in its sole and absolute discretion, believes are advisable.

Section 7.7 Indemnification.

A. To the maximum extent permitted by 61-2-109 of the Act, the Partnership shall indemnify each Indemnitee from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, attorneys fees and other legal fees and expenses), judgments, fines, settlements, and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, that relate to the operations of the Partnership as set forth in this Agreement in which such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise. Without limitation, the foregoing indemnity shall extend to any liability of any Indemnitee, pursuant to a loan guaranty or otherwise, for any indebtedness of the Partnership or any Subsidiary of the Partnership (including without limitation, any indebtedness which the Partnership or any Subsidiary of the Partnership has assumed or taken subject to) except as set forth pursuant to Exhibit E hereto in the Schedule of Guaranteed Debt Not Subject to Indemnity, and the General Partner is hereby authorized and empowered, on behalf of the Partnership, to enter into one or more indemnity agreements consistent with the provisions of this Section 7.7 in favor of any Indemnitee having or potentially having liability for any such indebtedness. The termination of any proceeding by judgment, order or settlement does not create a presumption that the Indemnitee did not meet the requisite standard of conduct set forth in this Section 7.7A with respect to the subject matter of such proceeding. The termination of any proceeding by conviction of an Indemnitee or upon a plea of nolo contendere or its equivalent by an Indemnitee,

I-20

or an entry of an order of probation against an Indemnitee prior to judgment, creates a rebuttable presumption that such Indemnitee acted in a manner contrary to that specified in this Section 7.7A. Any indemnification pursuant to this Section 7.7 shall be made only out of the assets of the Partnership, and neither the General Partner nor any Limited Partner shall have any obligation to contribute to the capital of the Partnership or otherwise provide funds, to enable the Partnership to fund its obligations under this Section 7.7.

B. Following a determination as provided in the Act that the facts then known would not preclude indemnification under Section 7.7A, reasonable expenses incurred by an Indemnitee who is a party to a proceeding may be paid or reimbursed by the Partnership in advance of the final disposition of the proceeding upon receipt by the Partnership of (i) a written affirmation by the Indemnitee of the Indemnitee’s good faith belief that the standard of conduct necessary for indemnification by the Partnership as authorized in this Section 7.7A has been met, and (ii) a written undertaking by or on behalf of the Indemnitee to repay the amount if it shall ultimately be determined that the standard of conduct has not been met.

C. The indemnification provided by this Section 7.7 shall be in addition to any other rights to which an Indemnitee or any other Person may be entitled under any agreement, pursuant to any vote of the Partners, as a matter of law or otherwise, and shall continue as to an Indemnitee who has ceased to serve in such capacity unless otherwise provided in a written agreement pursuant to which such Indemnitee is indemnified.

D. The Partnership may, but shall not be obligated to, purchase and maintain insurance, on behalf of the Indemnitees and such other Persons as the General Partner shall determine, against any liability that may be asserted against or expenses that may be incurred by such Person in connection with the Partnership’s activities, regardless of whether the Partnership would have the power to indemnify such Person against such liability under the provisions of this Agreement.

E. For purposes of this Section 7.7, the Partnership shall be deemed to have requested an Indemnitee to serve as fiduciary of an employee benefit plan whenever the performance by it of its duties to the Partnership also imposes duties on, or otherwise involves services by, it to the plan or participants or beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect to an employee benefit plan pursuant to applicable law shall constitute fines within the meaning of Section 7.7; and actions taken or omitted by the Indemnitee with respect to an employee benefit plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the participants and beneficiaries of the plan shall be deemed to be for a purpose which is not opposed to the best interests of the Partnership.

F. In no event may an Indemnitee subject any of the Partners to personal liability by reason of the indemnification provisions set forth in this Agreement.

G. An Indemnitee shall not be denied indemnification in whole or in part under this Section 7.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.

H. The provisions of this Section 7.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. Any amendment, modification or repeal of this Section 7.7 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the Partnership’s liability to any Indemnitee under this Section 7.7 as in effect immediately prior to such amendment, modification, or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.8 Liability of the General Partner.

A. Notwithstanding anything to the contrary set forth in this Agreement, the General Partner shall not be liable for monetary damages to the Partnership, any Partners or any Assignees for losses sustained or

I-21

liabilities incurred as a result of errors in judgment or of any act or omission if the General Partner acted in good faith, with the care an ordinarily prudent person in a like position would exercise under similar circumstances and in a manner the General Partner reasonably believes to be in the best interest of the Partnership.

B. The Limited Partners expressly acknowledge that the General Partner is acting on behalf of the Partnership, and its shareholders collectively, that the General Partner is under no obligation to consider the separate interests of the Limited Partners (including, without limitation, the tax consequences to Limited Partners or Assignees) in deciding whether to cause the Partnership to take (or decline to take) any actions, and that the General Partner shall not be liable for monetary damages for losses sustained, liabilities incurred, or benefits not derived by Limited Partners in connection with such decisions, provided that the General Partner has acted in good faith, with the care an ordinarily prudent person in a like position would exercise under similar circumstances and in a manner the General Partner reasonably believes to be in the best interest of the Partnership.

C. Subject to its obligations and duties as General Partner set forth in Section 7.1A hereof, the General Partner may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents. The General Partner shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the General Partner in good faith.

D. Any amendment, modification or repeal of this Section 7.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the General Partner’s liability to the Partnership and the Limited Partners under this Section 7.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.

Section 7.9 Other Matters Concerning the General Partner.

A. The General Partner may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, bond, debenture, or other paper or document believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties.

B. The General Partner may consult with legal counsel, accountants, appraisers, management consultants, investment bankers, architects, engineers, environmental consultants and other consultants and advisers selected by it, and any act taken or omitted to be taken in reliance upon the opinion of such Persons as to matters which such General Partner reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion, unless the General Partner has knowledge regarding such matter that makes reliance unwarranted.

C. The General Partner shall have the right, in respect of any of its powers or obligations hereunder, to act through any of its duly authorized officers and a duly appointed attorney or attorneys-in-fact. Each such attorney shall, to the extent provided by the General Partner in the power of attorney, have full power and authority to do and perform all and every act and duty which is permitted or required to be done by the General Partner hereunder.

D. Notwithstanding any other provisions of this Agreement or the Act, any action of the General Partner on behalf of the Partnership or any decision of the General Partner to refrain from acting on behalf of the Partnership, undertaken in the good faith belief that such action or omission is necessary or advisable in order to (i) protect the ability of the General Partner to continue to qualify as a REIT or (ii) avoid the General Partner’s incurring any taxes under Section 857 or Section 4981 of the Code, is expressly authorized under this Agreement and is deemed approved by all of the Limited Partners.

I-22

Section 7.10 Title to Partnership Assets. Title to Partnership assets, whether real, personal or mixed and whether tangible or intangible, shall be deemed to be owned by the Partnership as an entity, and no Partner, individually or collectively, shall have any ownership interest in such Partnership assets or any portion thereof. Title to any or all of the Partnership assets may be held in the name of the Partnership, the General Partner or one or more nominees, as the General Partner may determine, including Affiliates of the General Partner. The General Partner hereby declares and warrants that any Partnership assets for which legal title is held in the name of the General Partner or any nominee or Affiliate of the General Partner shall be held by the General Partner for the use and benefit of the Partnership in accordance with the provisions of this Agreement; provided, however, that the General Partner shall use its best efforts to cause beneficial and record title to such assets to be vested in the Partnership as soon as reasonably practicable. All Partnership assets shall be recorded as the property of the Partnership in its books and records, irrespective of the name in which legal title to such Partnership assets is held.

Section 7.11 Reliance by Third Parties. Notwithstanding anything to the contrary in this Agreement, any Person dealing with the Partnership shall be entitled to assume that the General Partner has full power and authority, without consent or approval of any other Partner or Person to encumber, sell or otherwise use in any manner any and all assets of the Partnership and to enter into any contracts on behalf of the Partnership, and take any and all actions on behalf of the Partnership and such Person shall be entitled to deal with the General Partner as if the General Partner were the Partnership’s sole party in interest, both legally and beneficially. Each Limited Partner hereby waives any and all defenses or other remedies which may be available against such Person to contest, negate or disaffirm any action of the General Partner in connection with any such dealing. In no event shall any Person dealing with the General Partner or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the General Partner or its representatives. Each and every certificate, document or other instrument executed on behalf of the Partnership by the General Partner or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (i) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (ii) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Partnership and (iii) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Partnership.

Section 8.2 Management of Business. No Limited Partner or Assignee (other than the General Partner, any of its Affiliates or any officer, director, employee, partner, agent or trustee of the General Partner, the Partnership or any of their Affiliates, in their capacity as such) shall take part in the operation, management or control (within the meaning of the Act) of the Partnership’s business, transact any business in the Partnership’s name or have the power to sign documents for or otherwise bind the Partnership. The transaction of any such business by the General Partner, any of its Affiliates or any officer, director, employee, partner, agent or trustee of the General Partner, the Partnership or any of their Affiliates, in their capacity as such, shall not affect, impair or eliminate the limitations on the liability of the Limited Partners or Assignees under this Agreement.

Section 8.3 Outside Activities of Limited Partners. Subject to any agreements entered into pursuant to Section 7.6E hereof and any other agreements entered into by a Limited Partner or its Affiliates with the Partnership or a Subsidiary, any Limited Partner (other than the General Partner) and any officer, director, employee, agent, trustee, Affiliate or shareholder of any Limited Partner (other than the General Partner) shall be entitled to and may have business interests and engage in business activities in addition to those relating to the

I-23

Partnership, including business interests and activities that are in direct competition with the Partnership or that are enhanced by the activities of the Partnership. Neither the Partnership nor any Partners shall have any rights by virtue of this Agreement in any business ventures of any Limited Partner or Assignee. None of the Limited Partners (other than the General Partner) nor any other Person shall have any rights by virtue of this Agreement or the Partnership relationship established hereby in any business ventures of any other Person (other than the General Partner to the extent expressly provided herein) and such Person shall have no obligation pursuant to this Agreement to offer any interest in any such business ventures to the Partnership, any Limited Partner or any such other Person, even if such opportunity is of a character which, if presented to the Partnership, any Limited Partner or such other Person, could be taken by such Person.

Section 8.4 Return of Capital. Except pursuant to the right of redemption set forth in Section 8.6, no Limited Partner shall be entitled to the withdrawal or return of its Capital Contribution, except to the extent of distributions made pursuant to this Agreement or upon termination of the Partnership as provided herein. Except to the extent provided by Exhibit D hereof or as permitted by Section 4.2B, or otherwise expressly provided in this Agreement, no Limited Partner or Assignee shall have priority over any other Limited Partner or Assignee either as to the return of Capital Contributions or as to profits, losses or distributions.

Section 8.5 Rights of Limited Partners Relating to the Partnership.

A. In addition to other rights provided by this Agreement or by the Act, and except as limited by Section 8.5C hereof, each Limited Partner shall have the right, for a purpose reasonably related to such Limited Partner’s interest as a limited partner in the Partnership, upon written demand with a statement of the purpose of such demand and at such Limited Partner’s own expense (including such copying and administrative charges as the General Partner may establish from time to time):

(1) to obtain a copy of the most recent annual and quarterly reports filed with the Securities and Exchange Commission by the General Partner pursuant to the Securities Exchange Act of 1934;

(2) to obtain a copy of the Partnership’s federal, state and local income tax returns for each Partnership Year;

(3) to obtain a current list of the name and last known business, residence or mailing address of each Partner;

C. Notwithstanding any other provision of this Section 8.5, the General Partner may keep confidential from the Limited Partners, for such period of time as the General Partner determines in its sole and absolute discretion to be reasonable, any information that (i) the General Partner reasonably believes to be in the nature of trade secrets or other information the disclosure of which the General Partner in good faith believes is not in the best interests of the Partnership or could damage the Partnership or its business or (ii) the Partnership is required by law or by agreements with an unaffiliated third party to keep confidential.

I-24

Section 8.6 Redemption Right.

A. Subject to Section 8.6C, each Limited Partner, other than the General Partner, shall have the right (the “Redemption Right”) to require the Partnership to redeem on a Specified Redemption Date all or a portion of the Common Units held by such Limited Partner at a redemption price equal to and in the form of the Cash Amount to be paid by the Partnership. The Redemption Right shall be exercised pursuant to a Notice of Redemption delivered to the Partnership (with a copy to the General Partner) by the Limited Partner who is exercising the redemption right (the “Redeeming Partner”). A Limited Partner may not exercise the Redemption Right for less than one thousand (1,000) Common Units or, if such Limited Partner holds less than one thousand (1,000) Common Units, all of the Common Units held by such Limited Partner. The Redeeming Partner shall have no right, with respect to any Partnership Units so redeemed, to receive any distributions paid after the Specified Redemption Date. The Assignee of any Limited Partner may exercise the rights of such Limited Partner pursuant to this Section 8.6, and such Limited Partner shall be deemed to have assigned such rights to such Assignee and shall be bound by the exercise of such rights by such Limited Partner’s Assignee. In connection with any exercise of such rights by such Assignee on behalf of such Limited Partner, the Cash Amount shall be paid by the Partnership directly to such Assignee and not to such Limited Partner.

B. Notwithstanding the provisions of Section 8.6A, the General Partner may, in its sole and absolute discretion, elect to assume directly and satisfy a Redemption Right by either paying to the Redeeming Partner the Cash Amount or issuing to the Redeeming Partner the REIT Shares Amount, as elected by the General Partner (in its sole and absolute discretion) on the Specified Redemption Date, whereupon the General Partner shall acquire the Partnership Units offered for redemption by the Redeeming Partner and shall be treated for all purposes of this Agreement as the owner of such Common Units, which upon such acquisition shall become Class B Common Units. Unless the General Partner (in its sole and absolute discretion) shall exercise its right to assume directly and satisfy the Redemption Right, the General Partner shall not have any obligation to the Redeeming Partner or the Partnership with respect to the Redeeming Partner’s exercise of the Redemption Right. In the event the General Partner shall exercise its right to satisfy the Redemption Right in the manner described in the first sentence of this Section 8.6B, the Partnership shall have no obligation to pay any amount to the Redeeming Partner with respect to such Redeeming Partner’s exercise of the Redemption Right, and each of the Redeeming Partner, the Partnership, and the General Partner shall treat the transaction between the General Partner, and the Redeeming Partner for federal income tax purposes as a sale of the Redeeming Partner’s Common Units to the General Partner. Each Redeeming Partner agrees to execute such documents as the General Partner may reasonably require in connection with the issuance of REIT Shares upon exercise of the Redemption Right.

C. Notwithstanding the provisions of Section 8.6A, Section 8.6B or any other provision of this Agreement, a Limited Partner (i) shall not be entitled to effect the Redemption Right for cash or an exchange for REIT Shares to the extent the ownership or right to acquire REIT Shares pursuant to such exchange by such Partner on the Specified Redemption Date could cause such Partner or any other Person to violate any of the restrictions on ownership and transfer of REIT Shares set forth in the Charter and (ii) shall have no rights under this Agreement to acquire REIT Shares which would otherwise be prohibited under the Charter. To the extent any attempted redemption or exchange for REIT Shares would be in violation of this Section 8.6C, it shall be null and void ab initio and such Limited Partner shall not acquire any rights or economic interest in the cash otherwise payable upon such redemption or the REIT Shares otherwise issuable upon such exchange.

D. Notwithstanding anything contained in Section 8.6A, 8.6B, or 8.6C, no Partner shall be entitled to exercise the Redemption Right pursuant to Section 8.6A with respect to any Preferred Unit unless (i) such Preferred Unit has been issued to and is held by a Partner other than the General Partner, and (ii) the General Partner has expressly granted to such Partner the right to redeem such Preferred Units pursuant to Section 8.6A.

E. Preferred Units shall be redeemed, if at all, only in accordance with such redemption rights or options as are set forth with respect to such Preferred Units (or class or series thereof) in the instruments designating such Preferred Units (or class or series thereof).

Any records maintained by or on behalf of the Partnership in the regular course of its business may be kept on, or be in the form of, punch cards, magnetic tape, photographs, micrographics or any other information storage device, provided that the records so maintained are convertible into clearly legible written form within a reasonable period of time.

B. As soon as practicable, but in no event later than one hundred five (105) days after the close of each calendar quarter (except the last calendar quarter of each year), the General Partner shall cause to be mailed to each Limited Partner as of the last day of the calendar quarter, a report containing unaudited financial statements of the Partnership, or of the General Partner, if such statements are prepared solely on a consolidated basis with the General Partner, and such other information as may be required by applicable law or regulation, or as the General Partner determines to be appropriate.

ARTICLE 10

TAX MATTERS

Section 10.1 Preparation of Tax Returns. The General Partner shall arrange for the preparation and timely filing of all returns of Partnership income, gains, deductions, losses and other items required of the Partnership for federal and state income tax purposes and shall use all reasonable efforts to furnish, within ninety (90) days of the close of each taxable year, the tax information reasonably required by Limited Partners for federal and state income tax reporting purposes.

Section 10.2 Tax Elections. Except as otherwise provided herein, the General Partner shall, in its sole and absolute discretion, determine whether to make any available election pursuant to the Code; provided, however, that the General Partner shall make the election under Section 754 of the Code in accordance with applicable regulations thereunder. The General Partner shall have the right to seek to revoke any such election (including, without limitation, the election under Section 754 of the Code) upon the General Partner’s determination in its sole and absolute discretion that such revocation is in the best interests of the Partners.

I-26

Section 10.3 Tax Matters Partner.

A. The General Partner shall be the “tax matters partner” of the Partnership for federal income tax purposes. Pursuant to Section 6230(e) of the Code, upon receipt of notice from the IRS of the beginning of an administrative proceeding with respect to the Partnership, the tax matters partner shall furnish the IRS with the name, address, taxpayer identification number, and profit interest of each of the Limited Partners and the Assignees; provided, however, that such information is provided to the Partnership by the Limited Partners and the Assignees.

B. The tax matters partner is authorized, but not required:

(1) to enter into any settlement with the IRS with respect to any administrative or judicial proceedings for the adjustment of Partnership items required to be taken into account by a Partner for income tax purposes (such administrative proceedings being referred to as a “tax audit” and such judicial proceedings being referred to as “judicial review”), and in the settlement agreement the tax matters partner may expressly state that such agreement shall bind all Partners, except that such settlement agreement shall not bind any Partner (i) who (within the time prescribed pursuant to the Code and Regulations) files a statement with the IRS providing that the tax matters partner shall not have the authority to enter into a settlement agreement on behalf of such Partner or (ii) who is a “notice partner” (as defined in Section 6231(a)(8) of the Code) or a member of a “notice group” (as defined in Section 6223(b)(2) of the Code);

(2) in the event that a notice of a final administrative adjustment at the Partnership level of any item required to be taken into account by a Partner for tax purposes (a “final adjustment”) is mailed to the tax matters partner, to seek judicial review of such final adjustment, including the filing of a petition for readjustment with the Tax Court or the filing of a complaint for refund with the United States Claims Court or the District Court of the United States for the district in which the Partnership’s principal place of business is located;

(3) to intervene in any action brought by any other Partner for judicial review of a final adjustment;

(4) to file a request for an administrative adjustment with the IRS and, if any part of such request is not allowed by the IRS, to file an appropriate pleading (petition or complaint) for judicial review with respect to such request;

(5) to enter into an agreement with the IRS to extend the period for assessing any tax which is attributable to any item required to be taken account by a Partner for tax purposes, or an item affected by such item; and

(6) to take any other action on behalf of the Partners of the Partnership in connection with any tax audit or judicial review proceeding to the extent permitted by applicable law or regulations.

The taking of any action and the incurring of any expense by the tax matters partner in connection with any such proceeding, except to the extent required by law, is a matter in the sole and absolute discretion of the tax matters partner and the provisions relating to indemnification of the General Partner set forth in Section 7.7 of this Agreement shall be fully applicable to the tax matters partner in its capacity as such.

C. The tax matters partner shall receive no compensation for its services. All third party costs and expenses incurred by the tax matters partner in performing its duties as such (including legal and accounting fees and expenses) shall be borne by the Partnership. Nothing herein shall be construed to restrict the Partnership from engaging an accounting firm to assist the tax matters partner in discharging its duties hereunder, so long as the compensation paid by the Partnership for such services is reasonable.

I-27

Section 10.4 Intentionally Deleted.

Section 10.5 Withholding. Each Limited Partner hereby authorizes the Partnership to withhold from or pay on behalf of or with respect to such Limited Partner any amount of federal, state, local, or foreign taxes that the General Partner determines that the Partnership is required to withhold or pay with respect to any amount distributable or allocable to such Limited Partner pursuant to this Agreement, including, without limitation, any taxes required to be withheld or paid by the Partnership pursuant to Sections 1441, 1442, 1445, 1446, or 1471 of the Code. Any amount paid on behalf of or with respect to a Limited Partner shall constitute a loan by the Partnership to such Limited Partner, which loan shall be repaid by such Limited Partner within fifteen (15) days after notice from the General Partner that such payment must be made unless (i) the Partnership withholds such payment from a distribution which would otherwise be made to the Limited Partner or (ii) the General Partner determines, in its sole and absolute discretion, that such payment may be satisfied out of the available funds of the Partnership which would, but for such payment, be distributed to the Limited Partner. Any amounts withheld pursuant to the foregoing clauses (i) or (ii) shall be treated as having been distributed to such Limited Partner. Each Limited Partner hereby unconditionally and irrevocably grants to the Partnership a security interest in such Limited Partner’s Partnership Interest to secure such Limited Partner’s obligation to pay to the Partnership any amounts required to be paid pursuant to this Section 10.5. In the event that a Limited Partner fails to pay any amounts owed to the Partnership pursuant to this Section 10.5 when due, the General Partner may, in its sole and absolute discretion, elect to make the payment to the Partnership on behalf of such defaulting Limited Partner, and in such event shall be deemed to have loaned such amount to such defaulting Limited Partner and shall succeed to all rights and remedies of the Partnership as against such defaulting Limited Partner. Without limitation, in such event the General Partner shall have the right to receive distributions that would otherwise be distributable to such defaulting Limited Partner until such time as such loan, together with all interest thereon, has been paid in full, and any such distributions so received by the General Partner shall be treated as having been distributed to the defaulting Limited Partner and immediately paid by the defaulting Limited Partner to the General Partner in repayment of such loan. Any amounts payable by a Limited Partner hereunder shall bear interest at the lesser of (A) the base rate on corporate loans at large United States money center commercial banks, as published from time to time in the Wall Street Journal, plus four (4) percentage points, or (B) the maximum lawful rate of interest on such obligation, such interest to accrue from the date such amount is due (i.e., fifteen (15) days after demand) until such amount is paid in full. Each Limited Partner shall take such actions as the Partnership or the General Partner shall request in order to perfect or enforce the security interest created hereunder.

Notwithstanding Section 11.2C, the General Partner may merge with another entity if immediately after such merger substantially all of the assets of the surviving entity, other than Partnership Units held by the General Partner (whether such Partnership Units constitute the General Partner Interest or a Limited Partner Interest), are contributed to the Partnership as a Capital Contribution in exchange for Partnership Units with a fair market value, as reasonably determined by the General Partner, equal to the 704(c) Value of the assets so contributed.

Section 11.3 Limited Partners’ Rights to Transfer.

A. Subject to the provisions of Section 11.3C, 11.3D, 11.3E, and 11.4, a Limited Partner may transfer, with or without the consent of the General Partner, all or any portion of its Partnership Interest, or any of such Limited Partner’s economic rights as a Limited Partner.

B. If a Limited Partner is subject to Incapacity, the executor, administrator, trustee, committee, guardian, conservator or receiver of such Limited Partner’s estate shall have all the rights of a Limited Partner, but not more rights than those enjoyed by other Limited Partners, for the purpose of settling or managing the estate and such power as the Incapacitated Limited Partner possessed to transfer all or any part of his or its interest in the Partnership. The Incapacity of a Limited Partner, in and of itself, shall not dissolve or terminate the Partnership.

C. The General Partner may prohibit any transfer by a Limited Partner of its Partnership Units if, in the opinion of legal counsel to the Partnership, such transfer would require filing of a registration statement under the Securities Act of 1933 or would otherwise violate any federal or state securities laws or regulations applicable to the Partnership or the Partnership Unit.

I-29

D. No transfer by a Limited Partner of its Partnership Units may be made to any Person if (i) in the opinion of legal counsel for the Partnership, it would result in the Partnership being treated as an association taxable as a corporation, or (ii) such transfer is effectuated through an “established securities market” or a “secondary market (or the substantial equivalent thereof)” within the meaning of Section 7704 of the Code.

Section 11.4 Substituted Limited Partners.

A. The General Partner’s failure or refusal to permit a transferee of any such interests to become a Substituted Limited Partner shall not give rise to any cause of action against the Partnership or any Partner.

B. A transferee who has been admitted as a Substituted Limited Partner in accordance with this Article 11 shall have all the rights and powers and be subject to all the restrictions and liabilities of a Limited Partner under this Agreement.

C.

Section 11.5 Assignees. If the General Partner, in its sole and absolute discretion, does not consent to the admission of any permitted transferee under Section 11.3 as a Substituted Limited Partner, as described in Section 11.4, such transferee shall be considered an Assignee for purposes of this Agreement. An Assignee shall be deemed to have had assigned to it, and shall be entitled to receive distributions from the Partnership and the share of Net Income, Net Losses, Recapture Income, and any other items, gain, loss deduction and credit of the Partnership attributable to the Partnership Units assigned to such transferee, but shall not be deemed to be a holder of Partnership Units for any other purpose under this Agreement, and shall not be entitled to vote such Partnership Units in any matter presented to the Limited Partners for a vote (such Partnership Units being deemed to have been voted on such matter in the same proportion as all other Partnership Units of the same class or series held by Limited Partners are voted, to the extent such Partnership Units are entitled to vote on such matter). In the event any such transferee desires to make a further assignment of any such Partnership Units, such transferee shall be subject to all the provisions of this Article 11 to the same extent and in the same manner as any Limited Partner desiring to make an assignment of Partnership Units.

Section 11.6 General Provisions.

A. No Limited Partner may withdraw from the Partnership other than as a result of a permitted transfer of all of such Limited Partner’s Partnership Units in accordance with this Article 11 or pursuant to redemption of all of its Partnership Units under Section 8.6.

B. Any Limited Partner who shall transfer all of its Partnership Units in a transfer permitted pursuant to this Article 11 shall cease to be a Limited Partner upon the admission of all Assignees of such Partnership Units as Substitute Limited Partners. Similarly, any Limited Partner who shall transfer all of its Partnership Units pursuant to a redemption of all of its Partnership Units under Section 8.6 of this Agreement shall cease to be a Limited Partner.

I-30

C. Transfers pursuant to this Article 11 may only be made on the first day of a month, unless the General Partner otherwise agrees; provided, however, that a transfer of Partnership Units pursuant to exercise of rights by a secured party in connection with a pledge of such Partnership Units may occur at any time.

D. If any Partnership Interest is transferred or assigned during any quarterly segment of the Partnership’s fiscal year in compliance with the provisions of this Article 11, or redeemed or transferred pursuant to Section 8.6 of this Agreement, or any day other than the first day of a Partnership Year, then Net Income, Net Losses, each item thereof and all other items attributable to such interest for such Partnership Year shall be divided and allocated between the transferor Partner and the transferee Partner by taking into account their varying interests during the Partnerships year in accordance with Section 706(d) of the Code, using the interim closing of the books method. Solely for purposes of making such allocations, each of such items for the calendar month in which the transfer or assignment occurs shall be allocated to the transferee Partner, and none of such items for the calendar month in which a redemption occurs shall be allocated to the Redeeming Partner. All distributions of Available Cash attributable to such Partnership Unit with respect to which the Partnership Record Date is before the date of such transfer, assignment, or redemption shall be made to the transferor Partner or the Redeeming Partner, as the case may be, and in the case of a transfer or assignment other than a redemption, all distributions of Available Cash thereafter attributable to such Partnership Unit shall be made to the transferee Partner.

In each case, the admission shall be subject to the successor General Partner executing and delivering to the Partnership an acceptance of all of the terms and conditions of this Agreement and such other documents or instruments as may be required to effect the admission.

B. Notwithstanding anything to the contrary in this Section 12.2, no Person shall be admitted as an Additional Limited Partner without the consent of the General Partner, which consent may be given or withheld in the General Partner’s sole and absolute discretion. The admission of any Person as an Additional Limited Partner shall become effective on the date upon which the name of such Person is recorded in the Partner Registry on the books and records of the Partnership, following the consent of the General Partner to such admission.

C. If any Additional Limited Partner is admitted to the Partnership on any day other than the first day of a Partnership Year, then Net Income, Net Losses, each item thereof and all other items allocable among Partners and Assignees for such Partnership Year shall be allocated among such Additional Limited Partner and all other Partners and Assignees by taking into account their varying interests during the Partnership Year in

ARTICLE 13

DISSOLUTION, LIQUIDATION AND TERMINATION

Section 13.1 Dissolution. The Partnership shall not be dissolved by the admission of Substituted Limited Partners or Additional Limited Partners or by the admission of a successor General Partner in accordance with the terms of this Agreement. Upon the withdrawal of the General Partner, any successor General Partner shall continue the business of the Partnership. The Partnership shall dissolve, and its affairs shall be wound up, upon the first to occur of any of the following (“Liquidating Events”):

A. the expiration of its term as provided in Section 2.5 hereof;

B. an event of withdrawal of the General Partner, as defined in the Act (other than an event of bankruptcy), unless, within ninety (90) days after such event of withdrawal Class A Limited Partners holding in the aggregate a majority of the issued and outstanding Class A Common Units agree in writing to continue the business of the Partnership and to the appointment, effective as of the date of withdrawal, of a successor General Partner;

C. entry of a decree of judicial dissolution of the Partnership pursuant to the provisions of the Act;

D. an election to dissolve the Partnership made by the General Partner and approved in writing by Class A Limited Partners holding in the aggregate a majority of the issued and outstanding Class A Common Units;

E. the sale of all or substantially all of the assets and properties of the Partnership; or

F. a final and non-appealable judgment is entered by a court of competent jurisdiction ruling that the General Partner is bankrupt or insolvent, or a final and non-appealable order for relief is entered by a court with appropriate jurisdiction against the General Partner, in each case under any federal or state bankruptcy or insolvency laws as now or hereafter in effect, unless prior to the entry of such order or judgment Class A Limited Partners holding in the aggregate a majority of the issued and outstanding Class A Common Units agree in writing to continue the business of the Partnership and to the appointment, effective as of a date prior to the date of such order or judgment, of a substitute General Partner.

Section 13.2 Winding Up.

A. Upon the occurrence of a Liquidating Event, the Partnership shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and

I-32

Partners. No Partner shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Partnership’s business and affairs. The General Partner, or, in the event there is no remaining General Partner, any Person elected by a majority in interest of the Limited Partners (the General Partner or such other Person being referred to herein as the “Liquidator”), shall be responsible for overseeing the winding up and dissolution of the Partnership and shall take full account of the Partnership’s liabilities and property and the Partnership property shall be liquidated as promptly as is consistent with obtaining the fair value thereof, and the proceeds therefrom (which may, to the extent determined by the General Partner, include shares of stock in the General Partner) shall be applied and distributed in the following order:

(1) First, to the payment and discharge of all of the Partnership’s debts and liabilities to creditors other than the Partners;

(2) Second, to the payment and discharge of all of the Partnership’s debts and liabilities to the General Partner;

(3) Third, to the payment and discharge of all of the Partnership’s debts and liabilities to the other Partners; and

(4) The balance, if any, to the General Partner and Limited Partners in accordance with their Capital Accounts, after giving effect to all contributions, distributions, adjustments, and allocations for all periods, and subject to the rights of the holders of Preferred Units to receive a liquidation preference, with an appropriate adjustment to the Capital Accounts of such holders entitled to receive a liquidation preference to reflect the payment of any such liquidation preference.

Prior to the foregoing distributions, the General Partner shall have made adjustments to Capital Accounts of the Partners to reflect the fair market value of the Partnership assets as of the date of the Partnership’s liquidation in a manner consistent with Regulations Section 1.704-1(b)(2)(iv)(f).

The General Partner shall not receive any additional compensation for any services performed pursuant to this Article 13.

B. Notwithstanding the provisions of Section 13.2A hereof which require liquidation of the assets of the Partnership, but subject to the order of priorities set forth therein, if prior to or upon dissolution of the Partnership the Liquidator determines that an immediate sale of part or all of the Partnership’s assets would be impractical or would cause undue loss to the Partners, the Liquidator may, in its sole and absolute discretion, defer for a reasonable time the liquidation of any assets except those necessary to satisfy liabilities of the Partnership (including to those Partners as creditors) and/or distribute to the Partners, in lieu of cash, as tenants in common and in accordance with the provisions of Section 13.2A hereof, undivided interests in such Partnership assets as the Liquidator deems not suitable for liquidation. Any such distributions in kind shall be made only if, in the good faith judgment of the Liquidator, such distributions in kind are in the best interest of the Partners, and shall be subject to such conditions relating to the disposition and management of such properties as the Liquidator deems reasonable and equitable and to any agreements governing the operation of such properties at such time. The Liquidator shall determine the fair market value of any property distributed in kind using such reasonable method of valuation as it may adopt.

C. In the discretion of the Liquidator, a pro rata portion of the distributions that would otherwise be made to the General Partner and Limited Partners pursuant to this Article 13 may be:

(1) distributed to a trust established for the benefit of the General Partner and Limited Partners for the purposes of liquidating Partnership assets, collecting amounts owed to the Partnership, and paying any contingent or unforeseen liabilities or obligations of the Partnership or of the General Partner arising out of or in connection with the Partnership. The assets of any such trust shall be distributed to the General Partner

I-33

and Limited Partners from time to time, in the reasonable discretion of Liquidator, in the same proportions as the amount distributed to such trust by the Partnership would otherwise have been distributed to the General Partner and Limited Partners Pursuant to this Agreement; or

(2) withheld or escrowed to provide a reasonable reserve for Partnership liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Partnership, provided that such withheld or escrowed amounts shall be distributed to the General Partner and Limited Partners in the manner and order of priority set forth in Section 13.2A as soon as practicable.

Section 13.3 Compliance with Timing Requirements of Regulations. In the event the Partnership is “liquidated” within the meaning of Regulations Section 1.704-l(b)(2)(ii)(g), distributions shall be made pursuant to this Article 13 to the General Partner and Limited Partners who have positive Capital Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(2). If any Partner has a deficit balance in his Capital Account (after giving effect to all contributions, distributions and allocations for all taxable years, including the year during which such liquidation occurs), except as set forth in Section 13.10, such Partner shall have no obligation to make any contribution to the capital of the Partnership with respect to such deficit, and such deficit shall not be considered a debt owed to the Partnership or to any other Person for any purpose whatsoever.

Section 13.4 Deemed Distribution and Recontribution. Notwithstanding any other provision of this Article 13, in the event the Partnership is considered liquidated within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g) but no Liquidating Event has occurred, the Partnership’s property shall not be liquidated, the Partnership’s liabilities shall not be paid or discharged, and the Partnership’s affairs shall not be wound up. Instead, for federal income tax purposes and for purposes of maintaining Capital Accounts pursuant to Exhibit C hereto, the Partnership shall be deemed to have distributed the property in kind to the General Partner and Limited Partners, who shall be deemed to have assumed and taken such property subject to all Partnership liabilities, all in accordance with their respective Capital Accounts. Immediately thereafter, the General Partner and Limited Partners shall be deemed to have recontributed the Partnership property in kind to the Partnership, which shall be deemed to have assumed and taken such property subject to all such liabilities.

Section 13.5 Rights of Limited Partners. Except as otherwise provided in this Agreement, each Limited Partner shall look solely to the assets of the Partnership for the return of its Capital Contributions and shall have no right or power to demand or receive property other than cash from the Partnership. Except as otherwise provided in this Agreement, no Limited Partner shall have priority over any other Partner as to the return of its Capital Contributions, distributions, or allocations.

Section 13.6 Notice of Dissolution. In the event a Liquidating Event occurs or an event occurs that would, but for provisions of an election by one or more Partners pursuant to Section 13.1, result in a dissolution of the Partnership, the General Partner shall, within thirty (30) days thereafter, provide written notice thereof to each of the Partners.

Section 13.7 Termination of Partnership and Cancellation of Certificate of Limited Partnership. Upon the completion of the liquidation of the Partnership cash and property as provided in Section 13.2 hereof, the Partnership shall be terminated, a certificate of cancellation shall be filed, and all qualifications of the Partnership as a foreign limited partnership in jurisdictions other than the State of Tennessee shall be canceled and such other actions as may be necessary to terminate the Partnership shall be taken.

Section 13.8 Reasonable Time for Winding-Up. A reasonable time shall be allowed for the orderly winding-up of the business and affairs of the Partnership and the liquidation of its assets pursuant to Section 13.2 hereof, in order to minimize any losses otherwise attendant upon such winding-up, and the provisions of this Agreement shall remain in effect between the Partners during the period of liquidation.

Section 13.9 Waiver of Partition. Each Partner hereby waives any right to partition of the Partnership property.

I-34

Section 13.10 Deficit Capital Account Restoration.

A. Subject to Section 13.10B, if a Class A Limited Partner listed on Schedule Section 13.10A (an “Electing Partner”) has a negative balance in his Capital Account on the date of the “liquidation” of his interest in the Partnership (within the meaning of Regulations Section 1.704-l(b)(2)(ii)(g) but excluding a constructive liquidation resulting from a tax termination of the Partnership under Section 708(b)(1)(B) of the Code)), then such Electing Partner shall contribute in cash to the capital of the Partnership the lesser of (i) the maximum amount (if any such maximum amount is stated) listed beside such Electing Partner’s name on Schedule Section 13.10A or (ii) the amount required to increase his Capital Account as of such date to zero. Any such contribution required of a Partner hereunder shall be made on or before the later of (i) the end of the Partnership Year in which the interest of such Partner is liquidated or (ii) the ninetieth (90th) day following the date of such liquidation. Notwithstanding any provision hereof to the contrary, all amounts so contributed by a Partner to the capital of the Partnership shall, upon the liquidation of the Partnership under this Article 13, be first paid to any then creditors of the Partnership, including Partners that are Partnership creditors (in the order provided in Section 13.2A), and any remaining amount shall be distributed to the other Partners then having positive balances in their respective Capital Accounts in proportion to such positive balances.

B. After the death of an Electing Partner, the executor of the estate of such an Electing Partner may elect to reduce (or eliminate) the deficit Capital Account restoration obligation of such an Electing Partner. Such election may be made by such executor by delivering to the General Partner within two hundred seventy (270) days of the death of such an Electing Partner a written notice setting forth the maximum deficit balance in his Capital Account that such executor agrees to restore under Section 13.10A, if any. If such executor does not make a timely election pursuant to this Section 13.10B (whether or not the balance in his Capital Account is negative at such time), then such Electing Partner’s estate (and the beneficiaries thereof who receive distributions of Partnership Units therefrom) shall be deemed to have a deficit Capital Account restoration obligation as set forth under Section 13.10A.

C. If the General Partner, on the date of the “liquidation” of its interest in the Partnership, within the meaning of Regulations Section 1.704-1 (b)(2)(ii)(g) (but excluding a constructive liquidation resulting from a tax termination of the Partnership under Section 708(b)(1)(B) of the Code), has a negative balance in its Capital Account, then the General Partner shall contribute in cash to the capital of the Partnership the amount needed to restore its Capital Account balance to zero. Any such contribution shall be made by the General Partner on or before the later of (i) the end of the Partnership Year in which the General Partner’s interest is liquidated, or (ii) the ninetieth (90th) calendar day following the date of such liquidation.

Following such proposal, the General Partner shall submit any proposed amendment to the Limited Partners. The General Partner shall seek the written vote of the Partners on the proposed amendment or shall call a meeting to vote thereon and to transact any other business that it may deem appropriate. For purposes of obtaining a written vote, the General Partner may require a response within a reasonable specified time, but not less than fifteen (15) days, and failure to respond in such time period shall constitute a vote which is consistent with the General Partner’s recommendation with respect to the proposal. Except as provided in Section 14.1B, 14.1C or 14.1D, a proposed amendment shall be adopted and be effective as an amendment hereto if it is approved by the General Partner and it receives the Consent of Partners holding a majority of the outstanding Common Units (including, for the avoidance of doubt, the Class B Common Units held by the Class B Limited Partner).

I-35

B. Notwithstanding Section 14.1A, the General Partner shall have the power, without the consent of the Limited Partners, to amend this Agreement as may be required to facilitate or implement any of the following purposes:

(3) to set forth the designations, rights, powers, duties, and preferences of the holders of any additional Partnership Interests issued pursuant to Section 4.2A hereof;

(4) to reflect a change that is of an inconsequential nature and does not adversely affect the Limited Partners in any material respect, or to cure any ambiguity, correct or supplement any provision in this Agreement not inconsistent with law or with other provisions, or make other changes with respect to matters arising under this Agreement that will not be inconsistent with law or with the provisions of this Agreement; and

(5) to satisfy any requirements, conditions, or guidelines contained in any order, directive, opinion, ruling or regulation of a federal or state agency or contained in federal or state law.

Further, no amendment may alter the restrictions on the General Partner’s authority set forth in Section 7.3 without the Consent specified in that section.

D. Notwithstanding Section 14.1A or Section 14.1B hereof, the General Partner shall not amend Section 4.2A, 7.5, 7.6, 11.2 or 14.2 without the Consent of Class A Limited Partners holding a majority of the Class A Common Units.

E. Notwithstanding anything in this Section 14.1 or elsewhere in this Agreement to the contrary, any amendment or restatement of the Partner Registry by the General Partner to reflect events or changes otherwise authorized or permitted by this Agreement shall not be deemed an amendment of this Agreement and may be done at any time and from time to time, as determined by the General Partner without the Consent of the Limited Partners and without any notice requirement. A copy of the Partner Registry is available to any Limited Partner upon written request to the General Partner.

Section 14.2 Meetings of the Partners.

A. Meetings of the Partners may be called by the General Partner and shall be called upon the receipt by the General Partner of a written request by Limited Partners holding twenty percent (20%) or more of the outstanding Common Units.

Notice of any such meeting shall be given to all Partners not less than seven (7) days nor more than thirty (30) days prior to the date of such meeting.

I-36

Partners is permitted or required under this Agreement, such vote or Consent may be given at a meeting of the Partners or may be given in accordance with the procedure prescribed in Section 14.1A hereof.

Any action required or permitted to be taken at a meeting of the Partners may be taken without a meeting if a written consent setting forth the action so taken is signed by a majority of the Percentage Interests of the Partners (or such other percentage as is expressly required by this Agreement). Such consent may be in one instrument or in several instruments, and shall have the same force and effect as a vote of a majority of the Percentage Interests of the Partners (or such other percentage as is expressly required by this Agreement).

D. Each meeting of Partners shall be conducted by the General Partner or such other Person as the General Partner may appoint pursuant to such rules for the conduct of the meeting as the General Partner or such other Person deems appropriate. Without limitation, meetings of Partners may be conducted in the same manner as meetings of the shareholders of the General Partner and may be held at the same time, and as part of, meetings of the shareholders of the General Partner.

CAPITAL ACCOUNT MAINTENANCE

1. Capital Accounts of the Partners

A. The Partnership shall maintain for each Partner a separate Capital Account in accordance with the rules of Regulations Section l.704-l(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions and any other deemed contributions made by such Partner to the Partnership pursuant to this Agreement and (ii) all items of Partnership income and gain (including income and gain exempt from tax) computed in accordance with Section 1.B hereof and allocated to such Partner pursuant to Section 6.1A of the Agreement and Exhibit D hereof, and decreased by (x) the amount of cash or Agreed Value of all actual and deemed distributions of cash or property made to such Partner pursuant to this Agreement and (y) all items of Partnership deduction and loss computed in accordance with Section 1.B hereof and allocated to such Partner pursuant to Section 6.1B of the Agreement and Exhibit D hereof. Notwithstanding any other provision of this Agreement, immediately after the contribution of assets and issuance of Class A Common Units resulting from the merger of George OP into the Partnership, the Capital Account of each Partner shall equal the product of (i) the number of Common Units owned by such Partner as of such time as set forth on Exhibit A and (ii) (A) the net asset value of the Partnership as determined by the General Partner divided by (B) the total number of Common Units then outstanding. The General Partner may determine such net asset value by valuing Common Units based on the Value of a REIT Share, but is not required to do so.

B. For purposes of computing the amount of any item of income, gain, deduction or loss to be reflected in the Partners’ Capital Accounts, unless otherwise specified in this Agreement, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes determined in accordance with Section 703(a) of the Code (for this purpose all items of income, gain, loss or deduction required to be stated separately pursuant to Section 703(a)(1) of the Code shall be included in taxable income or loss), with the following adjustments:

(1)

Except as otherwise provided in Regulations Section 1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and deduction shall be made without regard to any election under Section 754 of the Code which may be made by the Partnership, provided that the amounts of any adjustments to the adjusted bases of the assets of the Partnership made pursuant to Section 734 of the Code as a result of the distribution of property by the Partnership to a Partner (to the extent that such adjustments have not previously been reflected in the Partners’ Capital Accounts) shall be reflected in the Capital Accounts of the Partners in the manner and subject to the limitations prescribed in Regulations Section l.704 1(b)(2)(iv)(m)(4).

(2)

The computation of all items of income, gain, and deduction shall be made without regard to the fact that items described in Sections 705(a)(l)(B) or 705(a)(2)(B) of the Code are not includable gross income or are neither currently deductible nor capitalized for federal income tax purposes.

(3)

Any income, gain or loss attributable to the taxable disposition of any Partnership property shall be determined as if the adjusted basis of such property as of such date of disposition were equal in amount to the Partnership’s Carrying Value with respect to such property as of such date.

(4)

In lieu of the depreciation, amortization, and other cost recovery deductions taken into account in computing such taxable income or loss, there shall be taken into account Depreciation for such fiscal year.

(5)

In the event the Carrying Value of any Partnership Asset is adjusted pursuant to Section 1.D hereof, the amount of any such adjustment shall be taken into account as gain or loss from the disposition of such asset.

(6)

Any items specially allocated under Section 2 of Exhibit D hereof shall not be taken into account.

C. Generally, a transferee (including an Assignee) of a Partnership Unit shall succeed to a pro rata portion of the Capital Account of the transferor.

D. (1)

Consistent with the provisions of Regulations Section 1.704-1(b)(2)(iv)(f), and as provided in Section 1.D (2), the Carrying Values of all Partnership assets shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as of the times of the adjustments provided in Section 1.D (2) hereof, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property and allocated pursuant to Section 6.1 of the Agreement.

(2)

Such adjustments shall be made as of the following times: (a) immediately prior to the acquisition of an additional interest in the Partnership by any new or existing Partner in exchange for more than a de minimis Capital Contribution; (b) immediately prior to the distribution by the Partnership to a Partner of more than a de minimis amount of property as consideration for an interest in the Partnership; and (c) immediately prior to the liquidation of the Partnership within the meaning of Regulations Section 1.704-l(b)(2)(ii)(g), provided, however, that adjustments pursuant to clauses (a) and (b) above shall be made only if the General Partner determines that such adjustments are necessary or appropriate to reflect the relative economic interests of the Partners in the Partnership.

(3)

In accordance with Regulations Section 1.704 -l(b)(2)(iv)(e), the Carrying Value of Partnership assets distributed in kind shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Partnership property, as of the time any such asset is distributed.

(4)

In determining Unrealized Gain or Unrealized Loss for purposes of this Exhibit C, the aggregate cash amount and fair market value of all Partnership assets (including cash or cash equivalents) shall be determined by the General Partner using such reasonable method of valuation as it may adopt, or in the case of a liquidating distribution pursuant to Article 13 of the Agreement, shall be determined and allocated by the Liquidator using such reasonable methods of valuation as it may adopt. The General Partner, or the Liquidator, as the case may be, shall allocate such aggregate value among the assets of the Partnership (in such manner as it determines in its sole and absolute discretion to arrive at a fair market value for individual properties).

E. The provisions of this Agreement (including this Exhibit C and the other Exhibits to this Agreement) relating to the maintenance of Capital Accounts are intended to comply with Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner consistent with such Regulations. In the event the General Partner shall determine that it is prudent to modify the manner in which the Capital Accounts, or any debits or credits thereto (including, without limitation, debits or credits relating to liabilities which are secured by contributed or distributed property or which are assumed by the Partnership, the General Partner, or the Limited Partners) are computed in order to comply with such Regulations, the General Partner may make such modification without regard to Article 14 of the Agreement, provided that it is not likely to have a material effect on the amounts distributable to any Person pursuant to Article 13 of the Agreement upon the dissolution of the Partnership. The General Partner also shall (i) make any adjustments that are necessary or appropriate to maintain equality between the Capital Accounts of the Partners and the amount of Partnership capital reflected on the Partnership’s balance sheet, as computed for book purposes, in accordance with Regulations Section l.704-l(b)(2)(iv)(q), and (ii) make any appropriate modifications in the event unanticipated events might otherwise cause this Agreement not to comply with Regulations Section l.704-1(b).

2.	No Interest

No interest shall be paid by the Partnership on Capital Contributions or on balances in Partners’ Capital Accounts.

3.	No Withdrawal

No Partner shall be entitled to withdraw any part of his Capital Contribution or his Capital Account or to receive any distribution from the Partnership, except as provided in Article 4, 5, 7 and 13 of the Agreement.

EXHIBIT D

SPECIAL ALLOCATION RULES

1. Special Allocation Rules

Notwithstanding any other provision of the Agreement or this Exhibit D, the following special allocations shall be made in the following order:

A. Minimum Gain Chargeback. Notwithstanding the provisions of Section 6.1 of the Agreement or any other provisions of this Exhibit D, if there is a net decrease in Partnership Minimum Gain during any Partnership Year, each Partner shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to such Partner’s share of the net decrease in Partnership Minimum Gain, as determined under Regulations Section 1.704-2(g). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Section 1.704-2(f)(6). This Section 1.A is intended to comply with the minimum gain chargeback requirements in Regulations Section 1.704-2(f) and for purposes of this Section 1.A only, each Partner’s Adjusted Capital Account Deficit shall be determined prior to any other allocations pursuant to Section 6.1 of this Agreement with respect to such Partnership Year and without regard to any decrease in Partner Minimum Gain during such Partnership Year.

B. Partner Minimum Gain Chargeback. Notwithstanding any other provision of Section 6.1 of this Agreement or any other provisions of this Exhibit D (except Section 1.A hereof), if there is a net decrease in Partner Minimum Gain attributable to a Partner Nonrecourse Debt during any Partnership Year, each Partner who has a share of the Partner Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5), shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to such Partner’s share of the net decrease in Partner Minimum Gain attributable to such Partner Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(5). Allocations pursuant to the previous sentence shall be made in proportion to the respective amounts required to be allocated to each Partner pursuant thereto. The items to be so allocated shall be determined in accordance with Regulations Section 1.704 2(i)(4). This Section 1.B is intended to comply with the minimum gain chargeback requirement in such Section of the Regulations and shall be interpreted consistently therewith. Solely for purposes of this Section 1.B, each Partner’s Adjusted Capital Account Deficit shall be determined prior to any other allocations pursuant to Section 6.1 of the Agreement or this Exhibit with respect to such Partnership Year, other than allocations pursuant to Section 1.A hereof.

C. Qualified Income Offset. In the event any Partner unexpectedly receives any adjustments, allocations or distributions described in Regulations Sections 1.704-l(b)(2)(ii)(d)(4), l.704-1(b)(2)(ii)(d)(5), or 1.704-l(b)(2)(ii)(d)(6), and after giving effect to the allocations required under Sections 1.A and 1.B hereof, such Partner has an Adjusted Capital Account Deficit, items of Partnership income and gain (consisting of a pro rata portion of each item of Partnership income, including gross income and gain for the Partnership Year) shall be specifically allocated to such Partner in an amount and manner sufficient to eliminate, to the extent required by the Regulations, its Adjusted Capital Account Deficit created by such adjustments, allocations or distributions as quickly as possible.

D. Nonrecourse Deductions. Nonrecourse Deductions for any Partnership Year shall be allocated to the Partners in accordance with their respective Percentage Interests in Common Units. If the General Partner determines in its good faith discretion that the Partnership’s Nonrecourse Deductions must be allocated in a different ratio to satisfy the safe harbor requirements of the Regulations promulgated under Section 704(b) of the Code, the General Partner is authorized, upon notice to the Limited Partners, to revise the prescribed ratio to the numerically closest ratio for such Partnership Year which would satisfy such requirements.

E. Partner Nonrecourse Deductions. Any Partner Nonrecourse Deductions for any Partnership Year shall be specially allocated to the Partner who bears the economic risk of loss with respect to the Partner Nonrecourse Debt to which such Partner Nonrecourse Deductions are attributable in accordance with Regulations Section 1.704-2(i).

F. Priority Allocation With Respect to Preferred Units. Any remaining items of Partnership gross income or gain for the Partnership Year, if any, shall be specially allocated to the General Partner or any other Partner that holds Preferred Units in an amount equal to the excess, if any, of the cumulative distributions received by such Partner for or with respect to the current Partnership Year and all prior Partnership Years with respect to such Preferred Units (with a distribution made on the first business day after the end of a year being treated as made with respect to such year) (other than distributions that are treated as being in satisfaction of the Liquidation Preference Amount for any Preferred Units held by such Partner or amounts paid in redemption of any Preferred Units, except to the extent that the Liquidation Preference Amount or amount paid in redemption includes accrued and unpaid distributions) over the cumulative allocations of Partnership gross income and gain to such Partner under this Section 1.F for all prior Partnership Years.

G. Code Section 754 Adjustments. To the extent an adjustment to the adjusted tax basis of any Partnership asset pursuant to Section 734(b) or 743(b) of the Code is required, pursuant to Regulations Section 1.704-l(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis), and such item of gain or loss shall be specially allocated to the Partners in a manner consistent with the manner in which their Capital Accounts are required to be adjusted pursuant to such Section of the Regulations.

2. Allocations for Tax Purposes

A. Except as otherwise provided in this Section 2, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Partners in the same manner as its correlative item of “book” income, gain, loss or deduction is allocated pursuant to Section 6.1 of the Agreement and Section 1 of this Exhibit D.

B. Except as provided in Section 2.C of this Exhibit D, in an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, and deduction shall be allocated for federal income tax purposes among the Partners as follows:

(1)

(a)

In the case of a Contributed Property, such items attributable thereto shall be allocated among the Partners consistent with the principles of Section 704(c) of the Code to take into account the variation between the 704(c) Value of such property and its adjusted basis at the time of contribution; and

(b)

any item of Residual Gain or Residual Loss attributable to a Contributed Property shall be allocated among the Partners in the same manner as its correlative item of “book” gain or loss is allocated pursuant to Section 6.1 of the Agreement and Section 1 of this Exhibit D.

(2)

(a) In the case of an Adjusted Property, such items shall

(1)

first, be allocated among the Partners in a manner consistent with the principles of Section 704(c) of the Code to take into account the Unrealized Gain or Unrealized Loss attributable to such property and the allocations thereof pursuant to Exhibit C, and

(2)

second, in the event such property was originally a Contributed Property, be allocated among the Partners in a manner consistent with Section 2.B (1) of this Exhibit D; and

(b)

any item of Residual Gain or Residual Loss attributable to an Adjusted Property shall be allocated among the Partners in the same manner its correlative item of “book” gain or loss is allocated pursuant to Section 6.1 of the Agreement and Section 1 of this Exhibit D.

(3)

all other items of income, gain, loss and deduction shall be allocated among the Partners the same manner as their correlative item of “book” gain or loss is allocated pursuant to Section 6.1 of the Agreement and Section 1 of this Exhibit D.

C. To the extent Treasury Regulations promulgated pursuant to Section 704(c) of the Code permit a Partnership to utilize alternative methods to eliminate the disparities between the Carrying Value of property and its adjusted basis, the General Partner shall have the authority to elect the method to be used by the Partnership and such election shall be binding on all Partners.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Officers and Directors

The Tennessee Business Corporation Act, or the TBCA, sets forth in Sections 48-18-502 through 48-18-508 the circumstances governing the indemnification of directors, officers, employees and agents of a corporation against liability incurred in the course of their official capacities. Section 48-18-502 of the TBCA provides that a corporation may indemnify any director against liability incurred in connection with a proceeding if (i) the director acted in good faith, (ii) the director reasonably believed, in the case of conduct in his or her official capacity with the corporation, that such conduct was in the corporation’s best interest, or, in all other cases, that his or her conduct was not opposed to the best interests of the corporation and (iii) in connection with any criminal proceeding, the director had no reasonable cause to believe that his or her conduct was unlawful. In actions brought by or in the right of the corporation, however, the TBCA provides that no indemnification may be made if the director or officer is adjudged to be liable to the corporation. Similarly, the TBCA prohibits indemnification in connection with any proceeding charging improper personal benefit to a director, if such director is adjudged liable on the basis that a personal benefit was improperly received. In cases where the director is wholly successful, on the merits or otherwise, in the defense of any proceeding instigated because of his or her status as a director of a corporation, Section 48-18-503 of the TBCA mandates that the corporation indemnify the director against reasonable expenses incurred in the proceeding. Notwithstanding the foregoing, Section 48-18-505 of the TBCA provides that a court of competent jurisdiction, upon application, may order that a director or officer be indemnified for reasonable expense if, in consideration of all relevant circumstances, the court determines that such individual is fairly and reasonably entitled to indemnification, whether or not the standard of conduct set forth above was met. Officers, employees and agents who are not directors are entitled, through the provisions of Section 48-18-507 of the TBCA to the same degree of indemnification afforded to directors under Sections 48-18-503 and 48-18-505.

MAA’s charter provides that the MAA directors shall not be liable to MAA or its shareholders for monetary damages for breach of fiduciary duty, except for: (1) any breach of the director’s duty of loyalty; (2) for acts or omissions not in good faith or which involve intentional misconduct or knowing violation of law; or (3) unlawful distributions under Tennessee law. MAA’s charter provides further that MAA shall indemnify and advance expenses to a director, officer, employee or agent to the fullest extent permitted under Tennessee law.

The indemnification provisions in the MAA charter and bylaws specifically provide that MAA may purchase and maintain insurance on behalf of any MAA director or officer against any liability asserted against and incurred by him in his capacity as a director, officer, employee or agent whether or not MAA would have had the power to indemnify against such liability.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, or the Securities Act, may be permitted to the MAA directors and officers pursuant to the foregoing provisions or otherwise, MAA has been advised that, in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act, and is, therefore, unenforceable.

Item 21. Exhibits

A list of the exhibits included as part of this registration statement is set forth in the Exhibit Index that immediately precedes such exhibits and is incorporated herein by reference.

II-1

Item 22. Undertakings

The undersigned registrant hereby undertakes as follows:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933, as amended, to any purchaser: if the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933, as amended, to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

II-2

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended, (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned Registrant hereby undertakes as follows: That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

The Registrant undertakes that every prospectus: (i) that is filed pursuant to the immediately preceding paragraph, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act, as amended, and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act, as amended, may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
