PROXY STATEMENT

Summary Term Sheet

This Summary Term Sheet highlights selected information contained in this proxy statement and may not contain all of the information that is important to you. You are urged to read this entire proxy statement carefully, including the appendices and the section entitled "Where Stockholders Can Find More Information" on page [ ]. In this proxy statement, the terms "we," "us," "our," "TransMontaigne" and the "company" refer to TransMontaigne Inc. We refer to TransMontaigne Partners L.P. as "TransMontaigne Partners" and TransMontaigne GP L.L.C. as "TransMontaigne GP." We refer to UBS Securities LLC as "UBS." We refer to SemGroup, L.P. as "SemGroup," to SemGroup Subsidiary Holding, L.L.C. as "SemGroup Subsidiary" and to TMG Acquisition Company as "Merger Co". We refer to Morgan Stanley Capital Group Inc. as "Morgan Stanley."

Purpose of Stockholder Vote		You are being asked to consider and vote upon a proposal to adopt the Amended and Restated Agreement and Plan of Merger, dated as of May 22, 2006, by and among TransMontaigne, SemGroup, SemGroup Subsidiary and Merger Co, which we refer to as the "merger agreement" or the "May 22, 2006 merger agreement." Pursuant to the merger agreement, Merger Co will be merged with and into TransMontaigne, and TransMontaigne will be the surviving corporation. Following the merger, SemGroup Subsidiary will own all of our issued and outstanding capital stock. See "The Special Meeting" beginning on page [ ].
Parties involved in the Proposed Transaction		TransMontaigne is a Delaware corporation. SemGroup is an Oklahoma limited partnership. SemGroup Subsidiary is a Delaware limited liability company of which SemGroup is the sole member. Merger Co is a newly-formed Delaware corporation and a wholly owned subsidiary of SemGroup Subsidiary. See "Participants" beginning on page [ ].
Effect of Merger on TransMontaigne		Following completion of the merger, TransMontaigne, as the surviving corporation, will no longer have common stock quoted on the New York Stock Exchange. Our existing stockholders will no longer have an equity interest in TransMontaigne or participate in any potential future earnings and growth of TransMontaigne. See "The Merger—Effective Time of the Merger" beginning on page .
Effect of the Merger on Our Outstanding Capital Stock		Upon completion of the merger, (1) each issued and outstanding share of our common stock will be converted into the right to receive $11.25 in cash and (2) each issued and outstanding share of our Series B convertible preferred stock, which we refer to as "our preferred stock," will be converted into the right to receive $1,704.55 in cash or, at the holder's election, the right to receive $1,000 plus all accrued but unpaid dividends thereon through the redemption date indicated in the preferred stock certificate of designations. See "The Merger Agreement—Treatment of Our Stock in the Merger" beginning on page [ ].

Treatment of Outstanding Options and Restricted Stock Awards		Upon completion of the merger, each option that is not vested will become fully vested and all options will be cancelled in consideration for a cash payment. Any forfeiture restrictions in effect on shares of our restricted stock outstanding immediately prior to the effective time of the merger will be terminated and such shares will be converted into the right to receive $11.25 in cash. See "The Merger Agreement—Treatment of Our Stock in the Merger" beginning on page [ ].
Special Meeting		The stockholders' vote will take place at a special meeting of our stockholders to be held on [ ], 2006 at The Brown Palace Hotel, 321 Seventeenth Street, Denver, Colorado 80202, at [ : a.m.] local time. See "The Special Meeting" beginning on page [ ].
Record Date		You are entitled to vote at the special meeting if you owned shares of our common stock or preferred stock at the close of business on [ ], 2006, which is the record date for the special meeting. On the record date, shares of our common stock and shares of our preferred stock, convertible into shares of common stock, were outstanding and entitled to vote at the special meeting. See "The Special Meeting" beginning on page [ ].
Voting Information		Holders of our common stock will have one vote for each share of our common stock owned at the close of business on the record date. Holders of our preferred stock will have 151.52 votes for each share of our preferred stock owned at the close of business on the record date. The number of votes attributed to a share of preferred stock is equal to the number of shares of common stock that would be issued upon conversion of a share of preferred stock in accordance with its terms. For more information on how to vote your shares, please refer to "Questions and Answers About the Meeting and the Merger" and "The Special Meeting—How You Can Vote" beginning on pages [ ] and [ ], respectively.
Vote Required		The merger will be completed only if the merger agreement is adopted by the affirmative vote of a majority of the votes entitled to be cast by the holders of the outstanding shares of our common stock and preferred stock (as of the record date), voting together as a single class. This means that your failure to vote shares registered in your name or to give instruction to your broker or other nominee that holds shares beneficially owned by you will have the same effect as a vote against adoption of the merger agreement. On the record date, our directors and executive officers were deemed to beneficially own shares of our common stock and preferred stock representing, in the aggregate, approximately [ ]% of the outstanding votes entitled to be cast, and have indicated that, although they are not obligated to do so, they intend to vote their shares in favor of adoption of the merger agreement. See "Questions and Answers About the Meeting and the Merger" and "The Special Meeting — Record Date and Voting Information" beginning on pages [ ] and [ ], respectively.

Board Recommendations		Our board of directors has unanimously recommended that the holders of our common stock and preferred stock vote to adopt the merger agreement. In approving the merger agreement and related agreements, and recommending that you vote for the adoption of the merger agreement, our board of directors considered a number of factors. For a discussion of the factors considered by our board of directors. See "Special Factors—Reasons for Our Board of Directors' Recommendation; Factors Considered" beginning on page [ ].
Competing Offer—Background of the Merger		We originally entered into an agreement and plan of merger with SemGroup, SemGroup Subsidiary and Merger Co on March 27, 2006, which we refer to as the "March 27, 2006 merger agreement," under which SemGroup agreed to purchase all of our issued and outstanding equity securities for $9.75 per share. On Wednesday, April 26, 2006, we received a written offer from Morgan Stanley to purchase all of our issued and outstanding equity securities for $10.50 per share, in cash, and otherwise on substantially the same terms as the March 27, 2006 merger agreement. On April 28, 2006, our board of directors authorized our senior management to meet with representatives of Morgan Stanley to negotiate a definitive merger agreement in accordance with the terms of the Morgan Stanley offer. On May 8, 2006, our board of directors determined that the Morgan Stanley merger agreement constituted a "superior proposal" under the March 27, 2006 merger agreement. On May 12, 2006, following our receipt of an amended and restated merger agreement from SemGroup dated May 12, 2006, under which SemGroup agreed to purchase all of our issued and outstanding equity securities for $10.75 per share, our board of directors determined that the May 12, 2006 merger agreement with SemGroup was as least as favorable to our stockholders as the Morgan Stanley merger agreement and reaffirmed its recommendation to our stockholders to approve and adopt the May 12, 2006 merger agreement. On May 17, 2006, Morgan Stanley delivered a new formal binding offer for the acquisition of all of our outstanding shares of capital stock for $11.00 per share. On May 18, 2006, our board of directors determined that the Morgan Stanley merger agreement dated May 17, 2006 constituted a superior proposal. On May 23, 2006, following our receipt of an amended and restated merger agreement from SemGroup dated May 22, 2006, under which SemGroup agreed to purchase all of our issued and outstanding equity securities for $11.25 per share, our board of directors determined that the May 22, 2006 merger agreement from SemGroup was as least as favorable to our stockholders as the Morgan Stanley merger agreement dated May 17, 2006, and reaffirmed its recommendation to our stockholders to approve and adopt the May 22, 2006 merger agreement. See "Special Factors—Background of the Merger" on page [ ].
Opinion of UBS Securities LLC		UBS acted as financial advisor to our board of directors in connection with the transaction. On May 23, 2006, UBS delivered its opinion to our board of directors to the effect that, as of May 23, 2006, and based on and subject to various assumptions made, matters considered and limitations described in the opinion, the consideration of $11.25 per share was fair, from a financial point of view, to holders of our common stock.

		The full text of UBS' opinion describes, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by UBS. UBS' opinion is attached as Appendix B to this proxy statement. UBS' opinion is directed only to the fairness, from a financial point of view, of the per share consideration to be received in the merger by holders of our common stock and does not address any other aspect of the merger. The opinion also does not address the relative merits of the merger as compared to other business strategies or transactions that might be available to us or any underlying business decision of ours in connection with the merger or any other matter. The opinion does not constitute a recommendation to any holder of our common stock as to how such stockholder should vote or act with respect to any matters relating to the merger. You are encouraged to read UBS' opinion carefully in its entirety. The summary of UBS' opinion described above is qualified in its entirety by reference to the full text of the opinion. UBS' opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to UBS as of, the date of the UBS opinion. UBS does not have any obligation to update, revise or reaffirm its opinion. See "Special Factors—Opinion of Our Financial Advisor" beginning on page [ ].
Interests of Our Directors and Executive Officers in the Merger		In considering the recommendations of our board of directors, you should be aware that some directors and executive officers of TransMontaigne have interests in the merger that are in addition to, and different from, your interests as a stockholder and that may present actual or potential conflicts of interest. The board of directors considered these interests when making its decision to approve the merger agreement. These interests are discussed in detail in the section entitled "Special Factors—Interests of Our Directors and Executive Officers in the Merger" beginning on page [ ].
Merger Financing		TransMontaigne and SemGroup Subsidiary estimate that the total amount of funds necessary to complete the merger and related transactions, including the cost to redeem or repurchase our outstanding 9¹/8% Series B Senior Subordinated Notes due 2010, which we refer to as "our notes," which will take place after consummation of the merger, and to pay related fees and expenses, will be approximately $870 million.

Regulatory Approvals		The Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which we refer to as the "HSR Act," and the rules and regulations promulgated thereunder require that SemGroup and TransMontaigne file notification and report forms with respect to the merger and related transactions with the Antitrust Division of the U.S. Department of Justice and the U.S. Federal Trade Commission, which we refer to as the "FTC". The parties thereafter are required to observe a waiting period before completing the merger. The appropriate parties filed the necessary forms with the Department of Justice and the FTC on April 21, 2006. The initial waiting period was scheduled to expire on May 22, 2006; however, on that date the FTC issued a formal written request for the parties to supply additional information and documentary materials, which we refer to as a "second request." The second request extends and expands both the scope and the time frame covered by the FTC's previous information request to which we responded in full in our original filing with the FTC. Receipt of the second request from the FTC extends the original 30-day waiting period until 30 days following our compliance with the second request. Pursuant to the terms of the merger agreement, receipt of the second request extends the expiration date of the merger agreement from July 31, 2006 to December 31, 2006. We are not aware of any other material federal, state or local regulatory requirements or approvals that are required to complete the merger. See "The Merger—Regulatory Matters" on page [ ].
Material U.S. Federal Income Tax Consequences		The merger will be treated as a taxable transaction to our stockholders for U.S. federal income tax purposes. Holders should consult their tax advisors as to the tax consequences of the merger to them in light of their particular circumstances. See "The Merger—Material U.S. Federal Income Tax Consequences" beginning on page [ ].
Appraisal Rights		Our stockholders are entitled to appraisal rights under Delaware law if they follow the requirements specified in Section 262 of the Delaware General Corporation Law, which we refer to as the "DGCL." A copy of Section 262 of the DGCL is attached as Appendix C to this proxy statement. The obligation of each of SemGroup Subsidiary and Merger Co to complete the merger is subject to the condition that holders of not more than 15% of our shares of common stock, including shares issuable upon conversion of the preferred stock, have properly demanded and are entitled to appraisal of their shares in accordance with the provisions of Section 262 of the DGCL. See "The Merger—Appraisal Rights" on page [ ].

Limitations on Solicitation of Other Offers		We have agreed not to (1) solicit, initiate or knowingly encourage (including by way of furnishing non-public information or providing access to our properties, books, records or personnel) any inquiries regarding, (2) participate in any discussions or negotiations concerning, (3) execute or enter into any agreement, understanding or arrangement with respect to, (4) approve or recommend or propose to approve or recommend, (5) make any proposal or offer that constitutes, or could lead to or (6) enter into any agreement, understanding or arrangement with respect to, any acquisition proposal by a third party or certain types of alternative transactions, in each case while the merger is pending, except as permitted under the merger agreement. We have also agreed not to (1) take any action to exempt any third party from the restrictions on business combinations contained in Delaware law or (2) waive, terminate, modify or fail to enforce any provisions of any standstill agreement or similar obligation into which any third party has entered. In addition, our board of directors may not (1) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to SemGroup Subsidiary, its recommendation that our stockholders adopt the merger agreement, (2) approve or recommend, or propose publicly to approve or recommend, an acquisition proposal by a third party, (3) approve or recommend or allow us to enter into any letter of intent, acquisition agreement or any similar agreement or understanding related to an acquisition proposal by a third party or requiring us to abandon, terminate or fail to consummate the merger or any other transaction contemplated by the merger agreement or (4) effect any transaction contemplated by any acquisition proposal by a third party, except in each case as permitted under the merger agreement. See "The Merger Agreement—Covenants of TransMontaigne—Acquisition Proposals" beginning on page [ ].
Conditions		The obligations of either one or both of TransMontaigne and SemGroup Subsidiary to consummate the merger are subject to the prior satisfaction, or waiver to the extent permitted by law, of various conditions specified in the merger agreement, including conditions relating to, among other things, (1) the adoption of the merger agreement by our stockholders, (2) the provision for redemption of or amendment to our notes, (3) the absence of any law or governmental order prohibiting or enjoining the merger, (4) the expiration of any waiting periods under the HSR Act, (5) provision under SemGroup Subsidiary's financing to replace the existing credit facility of TransMontaigne Partners on terms reasonably acceptable to TransMontaigne GP, (6) the accuracy of the parties' respective representations and warranties, (7) the performance of the parties' respective obligations under the merger agreement in all material respects, (8) the absence of a material adverse effect with respect to TransMontaigne and (9) the number of shares with respect to which TransMontaigne stockholders have exercised rights of appraisal not exceeding an agreed upon maximum level. See "The Merger Agreement—Conditions to the Completion of the Merger" beginning on page [ ].

Termination		TransMontaigne and SemGroup Subsidiary may agree by mutual written consent to terminate the merger agreement at any time before the effective time of the merger. In addition, either TransMontaigne or SemGroup Subsidiary may terminate the merger agreement upon the occurrence of various events specified in the merger agreement, including, among other things, (1) the failure to consummate the merger by December 31, 2006, (2) the existence of a law or governmental order prohibiting the merger, (3) the failure of our stockholders to adopt the merger agreement or (4) the entry of a final order by a governmental antitrust authority of a nature more specifically described in the merger agreement.
		We may terminate the merger agreement if, among other things, (1) any of the representations and warranties of SemGroup Subsidiary and Merger Co contained in the merger agreement are or become untrue or inaccurate, (2) there has been a breach on the part of SemGroup Subsidiary or Merger Co of any of its covenants or agreements contained in the merger agreement (subject to cure), or (3) an agreement with respect to a superior proposal is entered into or there is a withdrawal or modification of the recommendation of the board of directors with respect to the merger (provided that the termination fee is paid).
		SemGroup Subsidiary may terminate the merger agreement if, among other things, (1) any of our representations and warranties contained in the merger agreement are or become untrue or inaccurate, (2) we have breached any of our covenants or agreements contained in the merger agreement (subject to cure), or (3) there is a withdrawal or modification of the recommendation of our board of directors with respect to the merger.
		See "The Merger Agreement—Termination" beginning on page [ ].
Expense Reimbursement Pursuant to the Merger Agreement		In specified circumstances, if the merger agreement is terminated before the effective time of the merger, we must pay a termination fee of $15 million to SemGroup Subsidiary. Similarly, in specified circumstances SemGroup must pay us a termination fee of $15 million. In addition, SemGroup has agreed to pay us a reverse termination fee of $10 million in the event the merger agreement is terminated either because the merger has not occurred prior to December 31, 2006, through no fault of TransMontaigne, or because SemGroup's compliance with a final, non-appealable order from a governmental antitrust authority would result in a material adverse effect on the conduct of the business of SemGroup, TransMontaigne and their affiliates, taken as a whole. See "The Merger Agreement—Fees and Expenses" beginning on page [ ].

Questions and Answers about the Meeting and the Merger

The following questions and answers are for your convenience only, and briefly address some commonly asked questions about the meeting and the merger. You should still carefully read this entire proxy statement, including the attached appendices.

Q:: Why am I receiving these materials?
A:: Our board of directors is providing these proxy materials to give you information for use in determining how to vote in connection with the special meeting of our stockholders and whether to seek appraisal of your shares.
Q:: What am I being asked to vote upon?
A:: You are being asked to consider and vote upon a proposal to adopt the merger agreement, pursuant to which Merger Co will merge with and into TransMontaigne, with TransMontaigne as the surviving corporation in the merger.
Q:: When and where is the special meeting?
A:: The special meeting of our stockholders will be held on [ ], 2006 at The Brown Palace Hotel, 321 Seventeenth Street, Denver, Colorado, at [ : a.m.] local time.
Q:: Who can vote on the merger agreement?
A:: All holders of our common stock and preferred stock at the close of business on [ ], 2006, the record date for the special meeting, may vote in person or by proxy on the adoption of the merger agreement at the special meeting.
Q:: What vote is required to adopt the merger agreement?
A:: The merger agreement must be adopted by the affirmative vote of a majority of the votes entitled to be cast by the holders as of the record date of our outstanding shares of common stock and preferred stock (which vote on an as-converted basis), voting together as a single class.
Q:: What will I receive in the merger?
A:: Upon completion of the merger, you will receive (1) $11.25 in cash for each issued and outstanding share of our common stock you own and (2) $1,704.55 in cash or, at your election, the right to receive $1,000 plus all accrued but unpaid dividends thereon through the redemption date indicated in the preferred stock certificate of designations, for each issued and outstanding share of our preferred stock you own. See "The Merger Agreement—Treatment of Our Stock in the Merger "beginning on page [ ].
Q:: When do you expect the merger to be completed?
A:: Because the merger is subject to certain conditions, the exact timing of the merger cannot be determined. On May 22, 2006, we received from the FTC a second request for additional information under the HSR Act. Receipt of the second request from the FTC extends the original 30-day waiting period until 30 days following our compliance with the FTC's supplemental information request. Pursuant to the terms of the merger agreement, receipt of the second request had the effect of extending the expiration date of the merger agreement from July 31, 2006 to December 31, 2006. We currently estimate that it may take us up to three months to compile the supplemental information requested by the FTC. Alternatively, the FTC's concerns may be resolved earlier through negotiations. The parties to the merger agreement, however, are working to complete the merger as soon as practicable. If the merger agreement is adopted and the other conditions to the merger are satisfied, including the expiration or termination of the waiting period

under the HSR Act, or waived, the merger is expected to be completed promptly after the special meeting.

(1): Voting by Mail. If you choose to vote by proxy through the mail, simply mark your proxy, date and sign it, and return it in the postage-paid envelope provided.

The failure to vote your shares by proxy either by telephone, via the Internet or by returning your proxy card or to vote in person at the meeting will have the same effect as voting against adoption of the merger agreement.

Q:

May I change my vote after I have mailed my signed proxy card?

A:

Yes. You may revoke and change your vote at any time before your proxy card is used at the meeting. You can do this by:

•: giving written notice of revocation to our secretary;
•: submitting another proper proxy by telephone, via the Internet or later-dated written proxy;
•: or attending the meeting and voting by paper ballot in person.

If you have instructed a broker to vote your shares, you must follow directions received from your broker to change those instructions.

Q:

If my shares are held in "street name" by my broker, will my broker vote my shares for me?

A:

Your broker will not be able to vote your shares without instructions from you. You should instruct your broker to vote your shares, following the procedures provided by your broker. Failure to instruct your broker to vote your shares will have the same effect as voting against adoption of the merger agreement.

Q:

What does it mean if I receive more than one set of materials?

A:

This means you own shares of our stock that are registered under different names. For example, you may own some shares directly as a stockholder of record and other shares through a broker; or you may own shares through more than one broker. In these situations, you will receive multiple sets of proxy materials. You must vote, sign and return all of the proxy cards or follow the instructions for any alternative voting procedure on each of the proxy cards that you receive in order to vote all of the shares you own. Each proxy card you receive comes with its own prepaid return envelope; if you vote by mail, make sure you return each proxy card in the return envelope that accompanies that proxy card.

Q:

If the merger is completed, how will I receive the cash for my shares?

A:

If the merger is completed, you will be contacted by Mellon Investor Services LLC, which will serve as the paying agent and will provide instructions that will explain how to surrender stock

certificates. You will receive cash for your shares from the paying agent after you comply with these instructions. If your shares of common stock are held in "street name" by your broker, you will receive instructions from your broker as to how to effect the surrender of your "street name" shares and receive cash for those shares.

Q:: Should I send in my stock certificates now?
A:: No. After the merger is completed, you will receive written instructions from the paying agent that will explain how to surrender stock certificates. See "The Merger—Payment of Merger Consideration and Surrender of Stock Certificates" beginning on page [ ].
Q:: What rights do I have to seek appraisal of my shares?
A:: You are entitled to appraisal rights under Delaware law if you follow the requirements specified in Section 262 of the DGCL. A copy of Section 262 of the DGCL is attached as Appendix C to this proxy statement. See "The Merger—Appraisal Rights" beginning on page [ ].
Q:: Who can help answer my questions?
A:: If you would like additional copies, without charge, of this proxy statement or if you have questions about the merger agreement or the merger, including the procedures for voting your shares, you should contact:

The Special Meeting

General

The enclosed proxy is solicited on behalf of our board of directors for use at a special meeting of our stockholders to be held on [ ], 2006 at The Brown Palace Hotel, 321 Seventeenth Street, Denver, Colorado, at [ : a.m.] local time, or at any adjournments or postponements of the special meeting, for the purposes set forth in this proxy statement and in the accompanying notice of special meeting. We intend to mail this proxy statement and the accompanying proxy card on or about [ ], 2006 to all stockholders entitled to vote at the special meeting.

At the special meeting, our stockholders are being asked to consider and vote upon a proposal to adopt the merger agreement. Our board of directors has approved the merger agreement and unanimously recommends that you vote "FOR" adoption of the merger agreement.

We do not expect a vote to be taken on any other matters at the special meeting. If any other matters are properly presented at the special meeting for consideration, however, the holders of all properly authorized proxies will have discretion to vote on these matters in accordance with their best judgment.

Please do not send in stock certificates at this time. If the merger is completed, you will be sent instructions regarding the procedures for exchanging your existing stock certificates for the appropriate per share cash payment. See "The Merger—Payment of Merger Consideration and Surrender of Stock Certificates" beginning on page [ ].

Record Date and Voting Information

Only holders of our common stock and preferred stock outstanding on [ ], 2006, the record date for the special meeting, are entitled to notice of and to vote at the special meeting. At the close of business on the record date, shares of our common stock and shares of our preferred stock, convertible into shares of common stock, were outstanding.

Each holder of record will have one vote for each share of our common stock owned at the close of business on the record date. Each holder of record will have 151.52 votes for each share of our preferred stock owned at the close of business on the record date, which is equal to the number of shares of common stock that would be issued upon conversion of a share of our preferred stock in accordance with its terms. The presence, in person or by proxy, of the holders of a majority of our outstanding shares of common stock and preferred stock, on an as-converted basis, entitled to vote at the special meeting is necessary to constitute a quorum for the transaction of business at the special meeting. Abstentions and broker non-votes will be counted as shares present and entitled to vote for the purpose of determining a quorum. "Broker non-votes" result when brokers are precluded from exercising their voting discretion with respect to the approval of non-routine matters such as the adoption of the merger agreement, and, thus, absent specific instructions from the beneficial owner of those shares, brokers are not permitted to vote the shares with respect to non-routine matters.

Adoption of the merger agreement requires the affirmative vote of a majority of the votes entitled to be cast at the meeting, that is, the majority of votes entitled to be cast by the following stockholders (in each case as of the record date), voting together as a single class: (1) holders of our common stock and (2) holders of our preferred stock. If you vote your shares of our common stock or preferred stock by submitting a properly executed and dated proxy card or by telephone or Internet proxy, your shares will be voted at the meeting as indicated on your signed proxy card, telephone proxy or Internet proxy. If no instructions are indicated on your signed proxy card or telephone proxy or Internet proxy, all of your shares represented by the proxy will be voted FOR the adoption of the merger agreement. Because the vote is based on the number of shares outstanding rather than on the number of votes cast, failure to vote your shares is effectively a vote against adoption of the merger agreement.

As of the record date, our directors and executive officers were deemed to beneficially own, in the aggregate, shares of our common stock and preferred stock, or collectively, approximately [ ]% of the outstanding votes entitled to be cast. Our directors and officers have indicated that, although they are not obligated to do so, they intend to vote their shares in favor of the adoption of the merger agreement.

How You Can Vote

You may vote your shares as follows:

•: Voting by Mail. If you choose to vote by proxy through the mail, simply mark your proxy, date and sign it, and return it in the postage-paid envelope provided.
•: Voting in Person. You can also vote by appearing and voting in person at the special meeting.
•: Voting by Telephone. You can vote your shares by proxy by telephone by calling the toll-free telephone number on your proxy card. Telephone voting is available 24 hours a day.
•: Voting by Internet. You can also vote your shares by proxy via the Internet. The web site for Internet voting is on your proxy card, and voting is also available 24 hours a day.

If you vote by telephone or via the Internet you should not return your proxy card. Instructions on how to vote by telephone or via the Internet are located on the proxy card enclosed with this proxy statement.

If your shares are held in the name of a bank, broker, trustee or other holder of record, including the trustee or other fiduciary of an employee benefit plan, you must obtain a proxy, executed in your favor, from the holder of record to be able to vote at the special meeting.

How You May Revoke or Change Your Vote

You can revoke your proxy at any time before it is voted at the meeting by:

•: giving written notice of revocation to our secretary, at our executive offices located at 1670 Broadway, Suite 3100, Denver, CO 80202
•: submitting another proper proxy by telephone, via the Internet or later-dated written proxy; or
•: attending the meeting and voting by paper ballot in person.

Expenses of Proxy Solicitation

We will bear the entire cost of solicitation of proxies, including preparation, assembly, printing and mailing of this proxy statement, the proxy card and any additional information furnished to you. Original solicitation of proxies by mail may be supplemented by telephone or personal solicitation by our directors, officers or other regular employees, who will not receive any additional compensation for these services. We have also hired The Altman Group to solicit proxies and to distribute proxy materials for the special meeting. The Altman Group also has agreed to provide proxy solicitation services with regard to banks, brokers, institutional investors and individual stockholders. We have agreed to pay The Altman Group a base fee of $8,100, an hourly rate of $110.00 for telephone solicitations, if necessary, plus reasonable out-of-pocket expenses for their services. Custodians, nominees and fiduciaries will be requested to forward the proxy soliciting materials to the beneficial owners of common stock held of record by those persons, and we will reimburse them for their charges and expenses.

Adjournments

Our restated bylaws provide that if an annual or special meeting of stockholders is adjourned, notice need not be given of any adjourned meeting if the time, date and place are announced at the meeting at which the adjournment occurs, so long as the adjourned meeting is no more than 30 days after the initial meeting date and no new record date is fixed for the adjourned meeting. If the meeting is adjourned for the purpose of soliciting additional proxies, our stockholders who have already sent in their proxies will be allowed to revoke them at any time prior to their use.

Special Factors

Background of the Merger

In July 2004, our board of directors authorized management to engage UBS Securities LLC to assist us in evaluating possible strategic alternatives, including a possible sale of TransMontaigne. UBS prepared materials regarding TransMontaigne and contacted numerous potentially interested parties including SemGroup, Plains All-American Pipeline L.P., Valero Energy Corporation and a team consisting of Morgan Stanley and Magellan Midstream Partners, L.P. No potential transaction emerged from that process and, in September 2004, our board of directors decided to discontinue a review of strategic alternatives. Instead, our board of directors instructed management to pursue both a product supply agreement with Morgan Stanley, which was completed as of November 4, 2004, and an initial public offering of our consolidated subsidiary, TransMontaigne Partners, which was completed on May 27, 2005. Following this process, we continued our normal-course, ongoing evaluation of our business, plans and strategic alternatives. As part of this process, our management, in consultation with our board of directors, periodically evaluated various alternatives for expanding our business and creating value for our stockholders, including through acquisitions of, or strategic combinations with, other petroleum product, distribution and supply companies.

During 2005, we engaged in ongoing conversations with Morgan Stanley regarding expanding and developing our business relationship and possible changes to our product supply agreement to address certain operating issues that had arisen under that agreement. On or about September 9, 2005, we initially raised with representatives of Morgan Stanley the possible sale of TransMontaigne to Morgan Stanley. On October 20, 2005, we executed a confidentiality agreement with Morgan Stanley and began to provide Morgan Stanley with due diligence information regarding TransMontaigne. From October 2005 through February 2006 we engaged in periodic discussions with Morgan Stanley regarding our business and prospects and the possibility that Morgan Stanley would acquire us, but no offer to acquire TransMontaigne was received until March 21, 2006, as described below.

On January 19, 2006, at SemGroup's invitation, Donald H. Anderson, our president and chief executive officer, Randall J. Larson, our executive vice president, chief financial and accounting officer, and William S. Dickey, our executive vice president and chief operating officer, met with Thomas L. Kivisto, SemGroup's chief executive officer, and Gregory C. Wallace, SemGroup's chief financial officer, to discuss possible commercial opportunities between SemGroup and TransMontaigne. The possibility of a business combination was not discussed at that time.

On March 2, 2006, Thomas L. Kivisto telephoned Donald H. Anderson and informed him that SemGroup was interested in making an offer to purchase TransMontaigne. On March 3, 2006, Thomas L. Kivisto telephoned Donald H. Anderson and asked if they could meet at Centennial Airport located outside of Denver, Colorado on Monday, March 6, 2006, to discuss SemGroup's potential offer to acquire TransMontaigne. On March 6, 2006, Messrs. Anderson, Kivisto and Wallace met for approximately one hour to discuss SemGroup's interest in acquiring TransMontaigne. As a result of this discussion, SemGroup delivered a letter dated March 6, 2006 to TransMontaigne setting forth its non-binding offer to acquire all of our issued and outstanding common stock (including stock issuable upon the exercise of any vested options or other rights to purchase) and preferred stock for a cash

purchase price of $9.75 per common share pursuant to a merger, tender offer or a combination of the foregoing. SemGroup's offer was conditioned upon:

•: the execution of a definitive agreement no later than March 31, 2006;
•: SemGroup's completion, to its sole satisfaction, of all due diligence prior to closing;
•: the closing to occur no later than June 30, 2006; and
•: our acceptance of the offer on or prior to March 13, 2006, at 5:00 p.m Central Standard Time.

The letter also requested that we agree to the following binding terms:

•: that, from the date of execution of the letter until the closing, we conduct our operations only in the ordinary course of business and not enter into any new contracts or amendments to existing contracts without advising SemGroup of any reasonably expected material impact to TransMontaigne as a result of such activity;
•: that we provide SemGroup and its representatives access to all documents, personnel, information or materials relating to our business;
•: that, from the date of execution of the letter until the closing, we not solicit, in any manner, or engage in negotiations with respect to, any alternative business combination transaction, which provision contained no exception permitting our board of directors to consider or accept superior alternative transactions that might emerge prior to closing (which we refer to as a "fiduciary out"); and
•: that we pay a break-up fee of $10,000,000 for any violation of the non-solicitation provisions.

On March 6, 2006, the date we received the non-binding offer letter from SemGroup, our common stock closed at $7.54 per share. From March 7, 2006 through Thursday, March 9, 2006, management discussed the terms of the offer letter internally and with its outside counsel, Morrison & Foerster. During this time, representatives of Morrison & Foerster discussed with senior management the necessity for adequate fiduciary out provisions in any definitive agreement, as well as the specific terms of possible fiduciary out provisions.

On March 9, 2006, at a regularly scheduled meeting of our board of directors, the board of directors met with management to discuss the potential transaction with SemGroup. At the conclusion of the meeting, the board of directors authorized our senior management to continue to engage in discussions with SemGroup, but not to accept the terms of the offer as written, primarily based on the following concerns:

•: entering into an exclusivity provision absent a fiduciary out could prevent our board of directors from achieving the highest value for our stockholders;
•: the possible negative impact to our results of operations and, potentially, our stock price resulting from the restrictions on TransMontaigne's day-to-day operations; and
•: the non-binding nature of the principal terms of the offer.

During the afternoon of Friday, March 9, 2006, management informed SemGroup that TransMontaigne was willing to pursue a transaction if SemGroup agreed to:

•: consider a possible increase in the price per share for our outstanding common stock and preferred stock;
•: a mutual break-up fee of $10,000,000;

•: limit the period after the execution of the merger agreement for SemGroup to conduct a "due diligence" review of our operations to 14 days because a longer or open-ended review could distract our personnel, which could have a negative impact on our operations; and
•: proceed on an accelerated basis and move directly to executing a definitive agreement, in lieu of negotiating the terms of a letter of intent, to reduce the disruption of our business likely to result from protracted negotiations.

The participants also discussed in principle our requirement that, should we elect to enter into a transaction with SemGroup, any definitive agreement with respect to such a transaction would have to contain an adequate fiduciary out provision.

As a result of these discussions, the parties agreed to prepare a term sheet setting forth the material terms upon which each party was willing to move forward and to meet in person to discuss the proposed terms the following day.

On Saturday, March 10, 2006, our senior management team comprised of Donald H. Anderson, William S. Dickey, Randall J. Larson, Frederick W. Boutin, our senior vice president and treasurer, Erik B. Carlson, our senior vice president and general counsel, and our outside counsel, met with SemGroup, represented by Gregory C. Wallace and representatives of SemGroup's outside counsel, Hall, Estill, Hardwick, Gable, Golden & Nelson, P.C., which we refer to as "Hall Estill," to discuss the terms of the proposed transaction. The initial proposal presented to SemGroup set forth the specific terms of the fiduciary out provisions we would require in any definitive agreement, including provisions related to the payment of a mutual termination, or break-up, fee by each of TransMontaigne and SemGroup under specified circumstances. The initial proposal also set forth substantially all of the material terms and conditions of the merger agreement, including conditions to closing, the treatment of our notes and various covenants.

Based on these discussions, later that Saturday, the parties agreed on the material terms upon which the parties were willing to proceed. Specifically, the parties agreed to:

•: increase the mutual termination fee from $10,000,000 to $15,000,000;
•: limit the period of SemGroup's due diligence review of TransMontaigne to 21 days to minimize the potential for disruption of our business that might result from a longer due diligence review period; and
•: the terms upon which SemGroup would agree to pay the termination fee to TransMontaigne.

On Saturday night and Sunday morning, the revised terms were incorporated into an initial draft of the merger agreement. On Sunday, March 11, 2006, our senior management and Morrison & Foerster met with SemGroup and Hall Estill to discuss the initial draft of the merger agreement. At this time the parties executed a mutual non-disclosure agreement.

On Monday, March 13 through Wednesday, March 15, 2006, representatives of SemGroup, including representatives of its commercial banker, Bank of America, N.A., met with our senior management team in Denver to conduct a business and financial due diligence review of TransMontaigne. At this time, SemGroup and TransMontaigne Partners entered into a mutual non-disclosure agreement so that we could discuss non-public information regarding TransMontaigne Partners. As a result of these discussions, SemGroup indicated that the cash purchase price it was willing to agree upon was $9.75 per share for our common stock.

On Tuesday, March 14, 2006, SemGroup informed us that it would not be able to deliver its financing commitment letters until early the following week and the anticipated signing of the merger agreement would need to be pushed back until the week of March 20, 2006.

On Friday, March 17, 2006, our board of directors met with senior management and our outside legal counsel to discuss the current terms of the merger agreement with SemGroup. The board discussed and considered soliciting or pursuing other indications of interest for TransMontaigne. Our board of directors concluded that it was more likely to achieve a higher value by focusing on negotiating a transaction with SemGroup. Our board of directors also determined that, if we were to pursue a transaction with SemGroup without first soliciting other indications of interest in TransMontaigne, it would require inclusion of a broad fiduciary out provision in the merger agreement.

At the March 17, 2006 meeting, our board of directors formally engaged UBS to act as its financial advisor for the potential transaction and evaluate and render an opinion with respect to the consideration to be received by holders of our common stock in the merger.

Also at the March 17, 2006 meeting, the board of directors considered the arrangements that had been made with respect to our management and employees in the transaction, including the proposed treatment of outstanding equity awards, the adoption of a severance program for our employees, excluding our executive officers, and the terms of the change of control agreements previously entered into with our senior management and other key officers.

On March 21, 2006, Donald H. Anderson received a written offer from Morgan Stanley to purchase TransMontaigne. Pursuant to the offer, Morgan Stanley proposed to purchase all of our issued and outstanding equity securities for $8.50 per common share. The offer was subject to completion of due diligence, the execution of definitive agreements and obtaining definitive financing commitments. The parent of Morgan Stanley publicly filed with the SEC an amendment to its Schedule 13D on March 22, 2006 disclosing the terms of the offer made to our board of directors. On March 21, 2006, our common stock closed at $7.42 per share. On March 22, 2006, our common stock closed at $9.22 per share.

On March 22, 2006, our board of directors and its financial and legal advisors met in Denver. Our board of directors received from Morrison & Foerster and Randall J. Larson an update on the status of the negotiations with SemGroup and the remaining unresolved issues. Our board of directors also received a detailed presentation from UBS, including various financial analyses utilizing different methodologies. Also at this meeting, Morrison & Foerster reviewed the fiduciary duties of our board of directors, as well as the principal terms and conditions of the proposed transaction with SemGroup as reflected in the draft merger agreement, including the circumstances related to the payment of termination fees; our ability to provide information to, and negotiate with, third parties concerning competing proposals; and the conditions to consummation of the transaction, including the condition related to SemGroup obtaining adequate financing to consummate the transaction.

Also at this meeting, our board of directors discussed the offer made by Morgan Stanley on March 21, 2006. After considering a number of factors, including (1) that the Morgan Stanley offer price was $1.25 per share below the price of the SemGroup offer, and (2) the possibility that pursuing the proposal could jeopardize the ongoing negotiations with SemGroup, or result in a decrease in SemGroup's proposed per share price, our board of directors decided not to take any action to pursue the Morgan Stanley offer further and instructed senior management to convey to Morgan Stanley that our board of directors had been advised of the terms of their offer. At the conclusion of the March 22 meeting, our board of directors directed our senior management team and advisors to continue negotiations with SemGroup in an effort to finalize the terms of the merger agreement.

After disclosure of the Morgan Stanley offer, two additional companies contacted us, one of which was Plains All American GP LLC, which we refer to as "Plains GP." Plains GP had spoken with us briefly at a conference for investors interested in master limited partnerships held in New York on March 8, 2006 and more extensively in a telephone conversation on March 14, 2006, where Plains GP informed us that they had continued to monitor and analyze the operations of TransMontaigne and TransMontaigne Partners subsequent to 2004. On March 23, 2006, we and Plains GP entered into a

mutual non-disclosure agreement, but no further discussions were held between us and Plains GP and no due diligence information was requested or provided pursuant to the mutual non-disclosure agreement.

On Thursday, March 23, 2006, we received draft commitment letters for the financing package which was to be arranged for SemGroup by Bank of America, N.A. and Banc of America Securities LLC. Our legal and financial advisors participated in discussions and revisions of the draft commitment letters over the course of the next several days, with a view toward improving the commitments from our perspective by reducing the conditionality contained therein.

On March 24, 2006, our chief financial officer, Randall J. Larson, returned a phone call to Valero Energy Corporation, which we refer to as "Valero," and engaged in a conversation with representatives of Valero who inquired about TransMontaigne's reaction to the offer from Morgan Stanley. Mr. Larson indicated that TransMontaigne was not in a position to comment on the Morgan Stanley offer. Although there was no discussion of a possible offer by Valero to acquire TransMontaigne, on March 24, 2006, Mr. Larson sent a mutual non-disclosure agreement to Valero, which Valero representatives signed and returned. Since March 24, 2006, we have had no further discussions with Valero and have not provided any information pursuant to the mutual non-disclosure agreement.

During the weekend of March 25, representatives of TransMontaigne and SemGroup worked to finalize the terms of the merger agreement, the financing commitment letters and related agreements and documentation.

On the morning of March 27, we received a letter from Plains GP dated March 26, 2006, under which Plains GP, as the general partner of Plains All American Pipeline, L.P., which we refer to as "Plains LP," offered to purchase, directly or indirectly, all of our outstanding common stock for $9.00 per common share, and to purchase each common unit of TransMontaigne Partners not owned by TransMontaigne for $31.00 per unit. The offer was subject to customary terms and conditions, but did not include a financing condition.

On March 27, 2006, our board of directors met to consider the proposed transaction with SemGroup. Management and representatives of Morrison & Foerster updated our board of directors on the results of the negotiations that had taken place since the previous meeting and described the final terms of the merger agreement and related transaction documents, including the final financing commitments. Our board of directors considered the terms of these agreements. Our board of directors then reviewed the Plains GP offer and taking into account the price of the offer at $9.00 per common share versus SemGroup's offer at a price of $9.75 per common share, the current status of the negotiations with SemGroup, and the possibility that pursuing the Plains GP proposal could jeopardize the ongoing negotiations with SemGroup, determined to move forward with SemGroup.

Next, representatives of UBS referred to its earlier financial analysis provided to our board of directors on March 22, 2006, and on March 27, 2006 delivered to our board of directors its opinion to the effect that, as of the date of the opinion and based on and subject to various assumptions made, the matters considered and limitations described in the opinion, that the consideration of $9.75 per share of common stock to be received by holders of our common stock was fair, from a financial point of view, to such holders.

Shortly after the meeting, and after the close of trading of our common stock on the New York Stock Exchange, TransMontaigne, SemGroup, SemGroup Subsidiary and Merger Co executed the merger agreement dated March 27, 2006, which we refer to as the "March 27, 2006 merger agreement," and issued a press release announcing the transaction.

On Wednesday, April 26, 2006, Donald H. Anderson received a written offer from Morgan Stanley to purchase all of our issued and outstanding equity securities for $10.50 per share, in cash, and otherwise on substantially the same terms as the March 27, 2006 merger agreement. Morgan Stanley's

offer was subject only to (1) satisfactory review and approval of the disclosure schedule and other schedules and exhibits to the merger agreement, (2) satisfactory completion of confirmatory due diligence, and (3) our execution of a definitive merger agreement with Morgan Stanley. The parent of Morgan Stanley publicly filed with the SEC an amendment to its Schedule 13D on April 27, 2006 disclosing the terms of the offer made to our board of directors.

On the evening of April 27, 2006, SemGroup, SemGroup Subsidiary and Merger Co waived the requirement that our board of directors first make a good faith determination that Morgan Stanley's offer could reasonably be expected to lead to a superior proposal prior to entering into negotiations with Morgan Stanley. At a board meeting held during the morning of April 28, 2006, our board authorized our senior management to meet with representatives of Morgan Stanley to negotiate a definitive merger agreement in accordance with the terms of the Morgan Stanley offer.

During the week of May 1, 2006 representatives of Morgan Stanley completed their due diligence review of TransMontaigne. On Friday, May 5, 2006, Morgan Stanley provided us with an initial draft of the merger agreement between Morgan Stanley, Buffalo Merger Sub Inc. and us. During the weekend of May 6, representatives of TransMontaigne and Morgan Stanley worked to finalize the terms of the merger agreement and related agreements and documentation.

By letter dated, May 8, 2006, Morgan Stanley delivered a formal binding offer for the acquisition of all of our outstanding shares of our capital stock for $10.50 per share, together with the definitive merger agreement, executed by Morgan Stanley, which we sometimes refer to as the "May 8, 2006 merger agreement." The offer was not subject to any due diligence or financing conditions and otherwise was substantially similar to the terms of the March 27, 2006 merger agreement with SemGroup. By its terms, the letter constituted a binding, irrevocable offer by Morgan Stanley to enter into the merger agreement. The offer would expire at 8:00 p.m. Denver time on Monday, May 8, 2006, unless our board of directors had notified SemGroup that it was prepared to terminate the March 27, 2006 merger agreement to enter into the Morgan Stanley merger agreement. If our board of directors delivered this notice, then the offer would expire at 5:00 p.m. Denver time on Friday May 12, 2006.

On May 8, 2006, our board of directors met to consider the terms of the Morgan Stanley offer letter and definitive May 8, 2006 merger agreement. Management and representatives of Morrison & Foerster updated our board of directors on the results of the negotiations that had taken place since the previous meeting and described the final terms of the May 8, 2006 merger agreement with Morgan Stanley and related transaction documents. After considering the terms of the May 8, 2006 merger agreement with Morgan Stanley and comparing such terms with the terms of the March 27, 2006 merger agreement with SemGroup, our board of directors determined that the Morgan Stanley merger agreement constituted a superior proposal. Our board of directors then authorized our senior management to notify SemGroup that our board of directors was prepared to terminate the March 27, 2006 merger agreement with SemGroup and enter into the May 8, 2006 merger agreement with Morgan Stanley. We notified SemGroup of our board's determination on May 8, 2006.

In response to our May 8, 2006 notification, on May 11, 2006, SemGroup delivered an amended and restated merger agreement dated May 12, 2006, which we refer to as the "May 12, 2006 merger agreement." The May 12, 2006 merger agreement provided for the acquisition of all of our outstanding shares of our capital stock for $10.75 per share. In addition, SemGroup eliminated the former financing condition as a prerequisite to closing, and substantially increased the financial threshold at which SemGroup would be permitted to terminate the transaction in the event of an unfavorable response from any governmental antitrust authority. Specifically, before SemGroup would be permitted to terminate the May 12, 2006 merger agreement, the effects of complying with the governmental antitrust authority's response would have to result in a material adverse effect upon the combined entities, taken as a whole.

On May 12, 2006, our board of directors met to consider the terms of the May 12, 2006 merger agreement with SemGroup. Management and representatives of Morrison & Foerster described to our board of directors the revised terms of the May 12, 2006 merger agreement and related transaction documents as compared to the May 8, 2006 merger agreement with Morgan Stanley. After considering the terms of the May 12, 2006 merger agreement with SemGroup as compared to the terms of the May 8, 2006 merger agreement with Morgan Stanley, our board of directors determined that the May 12, 2006 merger agreement with SemGroup was more favorable to our stockholders than the May 8, 2006 merger agreement with Morgan Stanley and authorized our officers to enter into the May 12, 2006 merger agreement. Our board of directors then authorized our senior management to notify Morgan Stanley that our board of directors was prepared to decline the May 8, 2006 merger agreement with Morgan Stanley and enter into the May 12, 2006 merger agreement with SemGroup. We notified Morgan Stanley and SemGroup of our board's determination on May 12, 2006.

By letter dated, May 17, 2006, Morgan Stanley delivered another binding, irrevocable offer for the acquisition of all of our outstanding shares of capital stock for $11.00 per share, together with the related definitive merger agreement, executed by Morgan Stanley, which we refer to as the "May 17, 2006 merger agreement." As compared to the May 8, 2006 merger agreement, the revised Morgan Stanley offer (1) increased to $50 million the financial threshold at which Morgan Stanley would be permitted to terminate the transaction in the event of an unfavorable response from any governmental antitrust authority and (2) included a termination fee of $17.5 million payable by Morgan Stanley to us in the event that Morgan Stanley exercised its right to terminate the May 17, 2006 merger agreement due to an unfavorable response from any governmental antitrust authority. The offer would expire at 8:00 p.m. Denver time on Thursday, May 18, 2006, unless our board of directors had notified SemGroup that it was prepared to terminate the existing May 12, 2006 merger agreement with SemGroup to enter into the May 17, 2006 merger agreement with Morgan Stanley. If our board of directors delivered this notice, then the offer would expire at 7:00 a.m. Denver time on Wednesday, May 24, 2006. The parent of Morgan Stanley publicly filed with the SEC an amendment to its Schedule 13D on May 18, 2006 disclosing the terms of the offer made to our board of directors.

On May 18, 2006, our board of directors met to consider the terms of the Morgan Stanley offer letter and definitive May 17, 2006 merger agreement. Management and representatives of Morrison & Foerster described the final terms of the May 17, 2006 merger agreement with Morgan Stanley as compared to the terms of the May 12, 2006 merger agreement with SemGroup. After considering the terms of the May 17, 2006 merger agreement as compared the terms of the existing May 12, 2006 merger agreement with SemGroup, our board of directors determined that the May 17, 2006 merger agreement with Morgan Stanley constituted a superior proposal. Our board of directors then authorized our senior management to notify SemGroup that our board of directors was prepared to terminate the May 12, 2006 merger agreement with SemGroup and enter into the May 17, 2006 merger agreement with Morgan Stanley. We notified SemGroup of our board's determination on May 18, 2006.

In response to our May 18, 2006, notification, on May 22, 2006, SemGroup delivered to us an amended and restated merger agreement dated May 22, 2006, which we refer to as the "merger agreement" or the "May 22, 2006 merger agreement." The May 22, 2006 merger agreement (1) increased the cash payment to holders of our common stock from $10.75 per share to $11.25 per share and (2) included a $10 million reverse termination fee payable by SemGroup to us in the event that the merger agreement was terminated either because the merger has not occurred prior to December 31, 2006, through no fault of TransMontaigne, or because SemGroup's compliance with a final, non-appealable order from a governmental antitrust authority would result in a material adverse effect on the conduct of the business of SemGroup, TransMontaigne and their affiliates, taken as a whole. The May 22, 2006 merger agreement also clarified that for such a material adverse effect to occur it would have to result in a minimum financial impact in excess of $50 million.

On May 22, 2006, we also received a second request from the FTC for TransMontaigne and SemGroup to supply additional information and documentary materials under the HSR Act. Receipt of the second request extended the original 30-day waiting period until 30 days following our compliance with the FTC's supplemental information request.

On May 23, 2006, our board of directors met to consider the terms of the May 22, 2006 merger agreement with SemGroup. Management and representatives of Morrison & Foerster described the final terms of the May 22, 2006 merger agreement with SemGroup as compared to the May 17, 2006 merger agreement with Morgan Stanley. In addition, representatives of Morrison & Foerster discussed the likely impact on the consummation of the merger due to the issuance of a second request from the FTC and the likelihood of receiving a similar request if TransMontaigne entered into the May 17, 2006 merger agreement with Morgan Stanley.

Next, representatives of UBS delivered to our board of directors its opinion dated May 23, 2006, to the effect that, as of the date of the opinion and based on and subject to various assumptions made, the matters considered and limitations described in the opinion, that the consideration of $11.25 per share of common stock to be received by holders of our common stock was fair, from a financial point of view, to such holders.

After considering the terms of the May 22, 2006 merger agreement with SemGroup as compared to the terms of the May 17, 2006 merger agreement with Morgan Stanley, our board of directors determined that the May 22, 2006 merger agreement with SemGroup was more favorable to our stockholders than the May 17, 2006 merger agreement with Morgan Stanley and authorized our officers to enter into the May 22, 2006 merger agreement. Our board of directors then authorized our senior management to notify Morgan Stanley that our board of directors was prepared to decline the May 17, 2006 merger agreement with Morgan Stanley and enter into the May 22, 2006 merger agreement with SemGroup. We notified Morgan Stanley and SemGroup of our board's determination on May 23, 2006.

Recommendation of Our Board of Directors

After consideration of the matters discussed above and the factors discussed in the next succeeding section of this proxy statement, our board of directors, by unanimous vote:

•: has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement, are advisable, fair to and in the best interests of the company and its stockholders;
•: has approved the merger, the merger agreement and the transactions contemplated by the merger agreement; and
•: recommends that our stockholders vote to adopt the merger agreement.

Reasons for Our Board of Directors' Recommendation; Factors Considered

In approving the merger agreement and related agreements, and recommending that you vote for the adoption of the merger agreement, our board of directors considered a number of factors, including the following material factors:

•: Our financial condition, results of operations, competitive position, business and prospects.
•: An assessment of TransMontaigne's projected cash flows, its ability to borrow money, and its needs for additional capital based on management's projections for TransMontaigne and taking into account the risks inherent in these projections.
•: A comparison of possible trading market multiples to the merger consideration being offered by SemGroup.

•: The results of the past efforts undertaken by TransMontaigne and UBS to solicit proposals to acquire TransMontaigne.
•: That the merger would provide our stockholders with cash consideration of $11.25 per common share, a price our board of directors views as attractive in light of our historical and current financial performance. Our board of directors also considered that the cash consideration of $11.25 per common share represents a 51.62% premium over the closing price of our common stock on March 21, 2006 of $7.42 per share (the last unaffected stock price prior to the press reports of a potential transaction), and a 51.21% and 45.16% premium over the closing price of our common stock one week and four weeks prior to March 21, 2006, which were $7.44 and $7.75 per share, respectively.
•: That the merger agreement with SemGroup resulted in our stockholders receiving an additional $0.25 per share as compared to the May 17, 2006 merger agreement with Morgan Stanley.
•: Our board of director's judgment that it was inadvisable to forgo the merger and pursue other alternatives because of the delays, uncertainties and contingencies, and business, economic and market risks involved.
•: That the merger consideration will be all cash, which provides certainty of value to our stockholders.
•: The offer by Morgan Stanley of a price of $8.50 per share on March 21, 2006, $10.50 per share on May 8, 2006 and $11.00 per share on May 17, 2006, for our common stock and the offer by Plains GP of a price of $9.00 per share for our common stock.
•: The written opinion of UBS delivered to our board of directors to the effect that, as of May 23, 2006, and based on and subject to the various assumptions made, matters considered and limitations described in the opinion, the consideration of $11.25 per common share to be received by holders of our common stock in the merger was fair, from a financial point of view, to such holders. The opinion of UBS is more fully described below under the caption "—Opinion of Our Financial Advisor."
•: The merger agreement, after giving consideration to the requirements and conditions set forth therein, allows us a reasonable opportunity to respond to certain third party acquisition proposals, and, if a superior proposal were made, to terminate the merger agreement and accept the superior proposal up until the time of the stockholder vote on the merger agreement, subject to certain limitations, including the payment of a termination fee. The board of directors considered that the merger agreement permits us to furnish information to, and enter into discussions with, third parties in response to unsolicited written proposals regarding a competing transaction if the board of directors determines in good faith, after consultation with outside legal counsel, that the failure to take any such action would be inconsistent with its fiduciary duties to our stockholders under applicable law. See "The Merger Agreement—Covenants of TransMontaigne—No Solicitation of Other Offers" for additional information regarding our ability to consider competing proposals.
•: Holders of our common stock who comply with Section 262 of the DGCL will have the opportunity to demand appraisal of the fair value of their shares.
•: That the merger agreement and the transactions contemplated thereby were the product of arms-length negotiations and that none of the members of our board of directors or senior management has an agreement with SemGroup or its affiliates to remain an executive, director or stockholder of the surviving corporation or SemGroup following the merger.
•: That SemGroup Subsidiary has received commitments from a reputable institution to provide financing with respect to the merger.

•: The limited number and nature of the conditions to SemGroup's obligation to close the merger, the size and reputation of SemGroup and that SemGroup eliminated the former financing condition as a prerequisite to closing, substantially increased the financial threshold at which SemGroup would be permitted to terminate the transaction in the event of an unfavorable response from any governmental antitrust authority and agreed to pay a reverse termination fee of $10 million if it did so, all of which led to our board of directors' opinion of an improved likelihood of a successful closing.
•: The procedural safeguards that have been put in place to ensure the fairness of the transactions to our stockholders.
•: Our preferred stockholders will receive the same form and amount of consideration in the proposed merger, on an as-converted basis, as our common stockholders.

Our board of directors also considered potentially negative factors in its deliberations concerning the merger, including:

•

That our stockholders will have no ongoing equity participation in TransMontaigne following the merger; such stockholders will cease to participate in our future earnings or growth, if any, or to benefit from increases, if any, in the value of our stock owned by them, and will not participate in any future sale of TransMontaigne to a third party.

•

That the cash consideration to be received by our stockholders may be taxable to them.

•

That we and our advisors did not recently solicit indications of interest from other parties who might be interested in engaging in a transaction with us prior to execution of the merger agreement. In this regard, the board of directors considered, among other factors:

•: the risk that delaying the negotiation of a merger agreement with SemGroup could lead to a reduction or withdrawal by SemGroup of its offer;
•: that TransMontaigne had actively sought buyers for the company less than two years previously and no acceptable offers for the company were made at that time;
•: the risk that an auction process or active solicitations of interest in us might be disruptive to our business and our employees, and might result in leaks of material, non-public information; and
•: the risk that the failure to engage in a transaction after an active sale process was conducted might cause the markets to have a negative view of TransMontaigne, especially after we had previously engaged in an auction for TransMontaigne in 2004 which resulted only in highly conditional offers at preliminary values too low to warrant further consideration.

•

The terms of the merger agreement providing that we will be responsible for (a) payment to SemGroup Subsidiary of a termination fee of $15 million if the merger agreement is terminated under specified circumstances, including if the merger agreement is terminated to accept a superior proposal, and that our obligation to pay the termination fee might discourage other parties from proposing a business combination with, or an acquisition of, TransMontaigne.

•

That, while the merger is expected to be completed, there can be no assurance that all conditions to the parties' obligations to complete the merger will be satisfied, and as a result, it is possible that the merger may not be completed even if approved by our stockholders.

•

The possibility of disruption to our operations following announcement of the merger, and the resulting effect on us if the merger does not close.

•: Although difficult to predict, that a merger agreement with Morgan Stanley would not likely result in the receipt of a second request for additional information from the FTC and, as a result, whether SemGroup's offer of $11.25 per share versus Morgan Stanley's offer of $11.00 per share was at least as favorable to our stockholders given the additional risks and delays in receiving clearance under the HSR Act by entering into the merger agreement with SemGroup.

The foregoing discussion of the information and factors considered by our board of directors is not intended to be exhaustive, but includes the material factors considered by our board of directors. Our board of directors collectively reached the unanimous decision to approve the merger agreement in light of the factors described above and other factors that each member of the board of directors felt was appropriate. In view of the variety of factors considered in connection with its evaluation of the merger, our board of directors did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors considered in reaching its determination and recommendation. In addition, individual directors may have given differing weights to different factors.

As described under the caption "—Interests of Our Directors and Executive Officers in the Merger," our board of directors was aware that certain of our directors and executive officers have interests in the merger that are, or may be, different from, or in addition to, the interests of our stockholders. Our board of directors was of the view that these interests, either alone or in connection with the factors discussed above, did not change its conclusion that it should authorize the merger and recommend the adoption of the merger agreement to our stockholders.

Opinion of Our Financial Advisor

On May 23, 2006, UBS delivered its opinion to our board of directors to the effect that, as of May 23, 2006, and based on and subject to various assumptions made, matters considered and limitations described in the opinion, the consideration of $11.25 per share of our common stock to be received by holders of our common stock in the merger was fair, from a financial point of view, to such holders.

The full text of UBS' opinion describes, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken by UBS. UBS' opinion is attached as Appendix B to this proxy statement. UBS' opinion is directed only to the fairness, from a financial point of view, of the per share consideration to be received in the merger by holders of our common stock and does not address any other aspect of the merger. The opinion also does not address the relative merits of the merger as compared to other business strategies or transactions that might be available to us or any underlying business decision of ours in connection with the merger or any other matter. The opinion does not constitute a recommendation to any holder of our common stock as to how such stockholder should vote or act with respect to any matters relating to the merger. Holders of our common stock are encouraged to read UBS' opinion carefully in its entirety. The summary of UBS' opinion described below is qualified in its entirety by reference to the full text of the opinion.

In arriving at its opinion, UBS:

•: reviewed certain publicly available business and historical financial information relating to TransMontaigne;
•: reviewed certain internal financial information and other data relating to our business and financial prospects that we provided to UBS and not publicly available, including financial forecasts and estimates prepared by our management;
•: conducted discussions with members of our senior management concerning our business and financial prospects;

•: reviewed publicly available financial and stock market data with respect to certain other companies UBS believed to be generally relevant;
•: compared the financial terms of the merger with the publicly available financial terms of certain other transactions UBS believed to be generally relevant;
•: reviewed current and historical market prices of our common stock;
•: reviewed a draft of the merger agreement; and
•: conducted such other financial studies, analyses and investigations, and considered such other information, as UBS deemed necessary or appropriate.

In connection with its review, with our consent, UBS did not assume any responsibility for independent verification of any of the information that UBS reviewed for the purpose of its opinion and, with our consent, UBS relied on that information being complete and accurate in all material respects. In addition, with our consent, UBS did not make any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of TransMontaigne or SemGroup, and UBS was not furnished with any such evaluation or appraisal. With respect to the financial forecasts and estimates referred to above, UBS assumed, at our direction, that they were reasonably prepared on a basis reflecting the best currently available estimates and judgments of our management as to our future performance. UBS' opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to UBS as of, the date of its opinion. UBS does not have any obligation to update, revise or reaffirm its opinion.

At our direction, UBS was not asked to and did not, offer any opinion as to the terms (other than the merger consideration) of the merger agreement or the form of the merger. UBS also assumed, with our consent, that (1) the final executed form of the merger agreement does not differ in any material respect from the draft dated May 22, 2006 that UBS examined; (2) the parties will comply with all material terms of the merger agreement; and (3) the merger will be consummated in accordance with the terms of the merger agreement without any adverse waiver or amendment to any material term or condition thereof. UBS has also assumed, with our consent, that all governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any material adverse effect on the parties or the merger. In 2004, UBS assisted TransMontaigne in contacting parties regarding a potential business combination with TransMontaigne; however, in connection with the merger, UBS has not been authorized to solicit, and has not solicited, indications of interest in a business combination with TransMontaigne from any party.

In furnishing its opinion, UBS did not purport that it is an expert within the meaning of the term "expert" as used in the Securities Act, nor did it purport that its opinion constitutes a report or valuation within the meaning of the Securities Act.

In connection with rendering its opinion, UBS performed a variety of financial and comparative analyses. The material analyses are summarized below. The following summary is not a complete description of all the analyses performed and factors considered by UBS in connection with its opinion. The preparation of a fairness opinion is a complex process involving subjective judgments and is not necessarily susceptible to partial analysis or summary description.

Accordingly, UBS believes that its analyses and the summary below must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying UBS' analyses and opinion. None of the analyses performed by UBS were assigned greater significance or reliance by UBS than any other. UBS did not form an opinion as to whether any individual analysis or factor, whether positive or negative, considered in isolation, supported or failed to support UBS' opinion. Rather, UBS arrived at

its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole, and believes that the totality of the factors considered and analyses it performed in connection with its opinion operated collectively to support its determination as to the fairness of the merger consideration from a financial point of view to the holders of our common stock.

The estimates of our future performance provided by our management in or underlying UBS' analyses are not necessarily indicative of actual values or actual future results, which may be significantly more or less favorable than those estimates. In performing its analyses, UBS considered industry performance, general business and economic conditions and other matters, many of which are beyond our control. Estimates of the financial value of companies do not necessarily purport to be appraisals or reflect the prices at which companies may actually be sold.

The merger consideration was determined through negotiation between TransMontaigne and SemGroup and the decision to enter into the merger agreement was solely that of our board of directors. UBS' opinion and financial analyses were only one of many factors considered by our board of directors in its evaluation of the proposed transaction and should not be viewed as determinative of the views of our board of directors or management with respect to the merger and the merger consideration.

The following is a summary of the material financial analyses performed by UBS and reviewed by our board of directors in connection with UBS' opinion relating to the proposed merger. The financial analyses summarized below include information presented in tabular format. In order to fully understand UBS' financial analyses, 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. Considering the data 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 UBS' financial analyses.

Analysis of Selected Publicly Traded Diversified General Partner C-Corporations

UBS compared selected financial information, ratios and public market values of TransMontaigne to corresponding financial information, ratios and public market values of the following selected publicly traded diversified general partner C-corporations in the midstream industry that UBS considered reasonably comparable, for purposes of this analysis, to TransMontaigne in certain respects:

•: Kinder Morgan Inc.;
•: Oneok, Inc.; and
•: MarkWest Hydrocarbon, Inc.

UBS reviewed, among other information, for each of TransMontaigne and the selected companies the ratio of the relevant company's total enterprise value, referred to as TEV, calculated as the market value of equity (in the case of the selected companies, based on March 22, 2006 closing stock prices and, in the case of TransMontaigne, based on March 21, 2006 closing stock price (the last trading day before public disclosure of the initial Morgan Stanley offer) and at the $11.25 offer price) plus total debt and other long-term liabilities, less cash and cash equivalents, to estimated EBITDA for 2006.

Estimated financial data for the selected companies were based on publicly available information, various research reports, and consensus estimates and for TransMontaigne were based on estimates provided by our management. This analysis indicated the following multiples:

					Total Enterprise Value / EBITDA
				Implied Enterprise Value ($ mm)	Total Enterprise Value / EBITDA
		Price as of 3/21/06 ($)	Market Value of Equity ($ mm)	Implied Enterprise Value ($ mm)	CY 2006E (x)
Diversified GP C-Corporation Mean					10.7	(2)
Diversified GP C-Corporation Median					10.7	(2)
TransMontaigne At Market
	TransMontaigne with No Dropdowns	7.42	437.0	560.4	10.2
	TransMontaigne Pro Forma for Brownsville/River Dropdown(1)	7.42	437.0	467.3	10.5
	TransMontaigne Pro Forma for Brownsville/River and Southeast facilities Dropdown(1)	7.42	437.0	353.9	11.6
At Offer
	TransMontaigne with No Dropdowns	11.25	664.1	787.5	14.3
	TransMontaigne Pro Forma for Brownsville/River Dropdown(1)	11.25	664.1	693.2	15.6
	TransMontaigne Pro Forma for Brownsville/River and Southeast facilities Dropdown(1)	11.25	664.1	579.1	18.9

(1): Change in enterprise value reflects after-tax cash proceeds from the assumed sale of the relevant facilities to TransMontaigne Partners ("Dropdown"), assumed to occur on December 31, 2005, and the expected accretion from TransMontaigne's ownership interests in TransMontaigne Partners and TransMontaigne GP. The resulting TEV/EBITDA multiple reflects both the TEV adjustments and lower EBITDA as a result of the asset sale(s). EBITDA excludes revenues and operating costs of TransMontaigne Partners' assets and includes distributions to be received from TransMontaigne Partners on the subordinated units, general partnership interest and incentive distribution rights of TransMontaigne Partners that we own.
(2): In the case of the selected companies, the TEV/EBITDA multiple was calculated based on May 22, 2006 closing stock prices.

None of the selected companies is either identical or directly comparable to TransMontaigne and any analysis of selected companies necessarily involves complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the public trading of the selected companies.

Selected Precedent Transportation and Storage Transactions

UBS analyzed certain information in 15 selected transportation and storage transactions in the oil and gas industry, each of which was announced since 2001. Financial data for the selected transactions were based on publicly available information, including publicly available research estimates and company filings, and for TransMontaigne, were based on estimates provided by our management. For each of the selected transactions, UBS calculated, where available, the ratio of total enterprise value to the one-year forward estimated EBITDA and compared the results of these calculations with corresponding calculations for the acquisition of TransMontaigne by SemGroup.

This analysis indicated the following implied ratios for the selected transactions as compared to the implied ratios for the acquisition of TransMontaigne by SemGroup:

		Offer for Equity ($ mm)	Total Enterprise Value ($ mm)	Total Enterprise Value / One Year Forward EBITDA
Selected Transactions:
High				12.7
Low				8.0
Mean				9.7
Median				9.1
TransMontaigne at $11.25 Offer:
	TransMontaigne with No Dropdowns	664.1	787.5	14.3
	TransMontaigne Pro Forma for Brownsville/River Dropdown(1)	664.1	693.2	15.6
	TransMontaigne Pro Forma for Brownsville/River and Southeast facilities Dropdown(1)	664.1	579.1	18.9

(1): Change in enterprise value reflects after-tax cash proceeds from the assumed sale of the relevant facilities to TransMontaigne Partners ("Dropdown"), assumed to occur on December 31, 2005, and the expected accretion from TransMontaigne's ownership interests in TransMontaigne Partners and TransMontaigne GP. The resulting TEV/EBITDA multiple reflects both the TEV adjustments and lower EBITDA as a result of the asset sale(s). EBITDA excludes revenues and operating costs of TransMontaigne Partners' assets and includes distributions to be received from TransMontaigne Partners on the subordinated units, general partnership interest and incentive distribution rights of TransMontaigne Partners that we own.

None of the selected precedent transactions is either identical or directly comparable to the merger and any analysis of selected precedent transactions necessarily involves complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition values of the companies concerned.

Discounted Cash Flow Analysis

UBS performed two discounted cash flow analyses to calculate the estimated present value of the stand-alone unlevered free cash flow that we could generate over fiscal years 2007 through 2011 based on internal estimates of our management. UBS' first discounted cash flow analysis assumed the Brownsville/River Dropdown was completed on July 1, 2006 and the Southeast facilities Dropdown was completed on July 1, 2007. UBS estimated the total value of TransMontaigne using a "sum-of-parts" methodology for each of (1) the after-tax Dropdown cash proceeds and distributions we receive as a result of being the general partner of, and of its limited partnership interests in, TransMontaigne Partners and (2) the cash flows from our marketing and trading operations. In the case of our Dropdowns, general and limited partnership interests, UBS applied a terminal multiple of between 15.0x and 30.0x to value the distributions from TransMontaigne Partners and discounted interim and terminal year cash flows to present value using discount rates ranging from 6.5% to 8.5%. In the case of our marketing and trading operations, UBS applied terminal perpetuity growth rates of between (1.0%) and 1.0% and used discount rates ranging from 17.0% to 19.0% to present value the interim and terminal year cash flows.

Also included in the marketing and trading valuation is the fair market value of inventories, product linefill and tank bottoms volumes, less anticipated changes in inventory levels due to our

ongoing business operations, less the current balance of the working capital facility, all of which were based on estimates provided by our management, monetized at the end of the 5-year forecast period and discounted at the 10-year U.S. treasury rate of 5.0% as of March 22, 2006. UBS then calculated a range of consolidated enterprise values combining the two parts of our business by adding the enterprise values calculated for each segment using low, medium and high ranges for the terminal value drivers and discount rates used for each segment. This analysis indicated an implied per share equity reference range of $7.65 to $9.76 for TransMontaigne, as compared to the merger consideration of $11.25 per share.

UBS also performed a second discounted cash flow analysis that did not assume the completion of the Dropdowns. For this analysis, UBS calculated a terminal value based on a range of multiples of estimated consolidated 2011 EBITDA and discounted to present value using discount rates ranging from 8.0% to 9.0%. This analysis indicated an implied per share equity reference range of $4.85 to $5.99 for TransMontaigne, as compared to the merger consideration of $11.25 per share:

Other Factors

In rendering its opinion, UBS also reviewed and considered other information and data, including:

•: the closing price of our common stock on March 21, 2006, the last trading day before public disclosure of the initial Morgan Stanley offer, and average closing prices over specified periods preceding March 21, 2006 and calculated the premium of the offered merger consideration over these historical prices; and
•: selected purchase price per share premiums paid in mergers and acquisitions greater than $300 million and less than $3.0 billion with 100% cash consideration occurring between March 22, 2003 and March 22, 2006.

Miscellaneous

Under the terms of UBS engagement, we have agreed to pay UBS a fee for rendering its financial fairness opinion, which was independent of the result of the opinion, and an additional fee payable upon the completion of the merger, against which the opinion fee will be credited to the extent previously paid. In addition, we have agreed to reimburse UBS for its reasonable expenses, including fees and disbursements of its counsel, and to indemnify UBS against liabilities, including liabilities under the federal securities laws, relating to or arising out of its engagement as our financial advisor. UBS and its affiliates have in the past provided services to us unrelated to the proposed merger, for which services UBS and its affiliates have received compensation.

We selected UBS as our financial advisor in connection with the merger because UBS is an internationally recognized investment banking firm with substantial experience in similar transactions and due to the tail provision contained in our July 28, 2004 engagement letter with UBS that generally obligated us to pay UBS a fee if, prior to June 30, 2006, we entered into any business combination transaction with any of the parties specified in connection with that engagement. Prior to our engagement of UBS in July 2004, UBS had previously provided capital raising and other financial advisory services for TransMontaigne since February 2003, and as a result was familiar with our operations. UBS, as part of its investment banking services, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, strategic transactions, corporate restructurings, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes.

In the ordinary course of business, UBS, its successors and affiliates may hold or trade, for their own accounts and the accounts of their customers, securities of TransMontaigne and SemGroup and their respective affiliates and, accordingly, may at any time hold a long or short position in such securities.

Interests of Our Directors and Executive Officers in the Merger

In considering the recommendation of our board of directors with respect to the merger, you should be aware that certain of our executive officers and directors have interests in the transactions contemplated by the merger agreement that may be different from, or in addition to, the interests of our stockholders generally. Our board of directors was aware of these interests and considered them, among other matters, in making its recommendation.

Severance and Termination Arrangements

We entered into change in control agreements with Messrs. Anderson, Boutin, Carlson and Dickey on April 12, 2001, and with Randall J. Larson on May 1, 2002, each of whom is referred to as our "executive." The agreements provide the executives with compensation and benefits in the event of a change in control, which definition would include the completion of the merger.

Under the agreement, if we currently employ the executive on the date of an actual or threatened change in control, we will continue to employ the executive for the period commencing on the date of the actual change in control and ending on the last day of the term of the agreement; however, the then existing term will be automatically extended for an additional two years after the month in which the change in control occurs. In addition, if the executive is terminated prior to the date on which the change in control occurs and the executive reasonably demonstrates that such termination arose in connection with, or in anticipation of, a change in control, then executive is entitled to the termination benefits discussed below.

Under the agreements, if the executive is terminated for any reason other than death or cause, or if the executive resigns for good reason, we are required to pay the executive the following amounts:

•: a cash lump sum payment within ten days of the date of termination equal to the sum of (1) two times the executive's annual salary and target bonus in effect immediately prior to the date of termination, and (2) the pro-rated portion of the executive's assigned target bonus for the year of termination;
•: all medical, health and other insurance benefits and perquisites for 24 months, or until the executive becomes eligible for comparable benefits; and
•: upon the executive's request, outplacement services for six months at a maximum cost of $30,000.

The agreements provide that termination for cause means an uncured breach of the agreement, conviction of a felony, or willful dishonesty, or fraud upon, or material bad faith action with respect to TransMontaigne. Termination for "good reason" by the executive is defined to include, but not be limited to the following events:

•: the assignment to the executive of duties inconsistent with, or a substantial alteration in the nature or status of, the executive's responsibilities immediately prior to a change in control;
•: a reduction in the executive's compensation or benefits, including equity-based incentive plans, as in effect on the date of a change in control;
•: a relocation of our principal offices to a location outside the Denver, Colorado metropolitan area, or the executive's relocation to any place other than our Denver, Colorado offices;
•: our material breach of any provision of the agreement, if such material breach has not been cured within 30 days; or
•: our failure to obtain the assumption and performance of the agreement by any successor, by merger, consolidation or otherwise.

Unlike the other agreements, Mr. Anderson's agreement also permits him to terminate the agreement, if he determines, in his sole discretion, that circumstances have so changed that he is not willing to continue in his position with TransMontaigne.

In addition, under the agreements, we would be obligated to make tax reimbursement payments to any former executive if any amounts he receives are subject to an excise tax under Section 4999 of the Internal Revenue Code, which taxes some payments that are contingent on a change-of-control within the meaning of Section 280G of the Internal Revenue Code. The issues relating to the determination of the amount of tax for which we will be liable for reimbursement are complex and subject to varied interpretations. We are obligated to make a tax reimbursement payment to an executive in an amount which would put the executive in approximately the same financial position he would have been in if the excise tax did not apply to those payments. At the present time, we are not certain whether any tax reimbursement payments will be required.

The merger agreement provides that the surviving corporation will generally continue the salary and benefits of our employees, including the executives, in effect before the merger. The surviving corporation is not, however, required to continue our equity incentive plan following the merger and has indicated that it does not intend to do so. As a result, as discussed above, the executives would be entitled to terminate their employment for "good reason" after the merger and receive the severance payments due under the change in control agreements. Accordingly, in order to provide the executives with an incentive to continue with the surviving corporation to promote an orderly transition, we offered each of our executives the option to amend his agreement to add a "stay bonus" feature. The terms of the stay bonus are as follows: (1) if the executive remains employed by TransMontaigne for at least six months, referred to as the "stay period," following a change in control, or (2) in the event the executive is terminated for any reason other than cause before the end of the stay period, or (3) if the executive exercises his right to terminate his employment with TransMontaigne for good reason, then the executive would be entitled to receive the full cash amount of the severance payments as set forth above and related termination benefits. In the event the executive remains employed for the duration of the stay period and the executive receives the stay bonus and related termination benefits, the executive would not thereafter be entitled to receive any additional severance payment under the agreement for any reason. As of , 2006, Messrs. , and had elected to amend their change in control agreements.

SemGroup has not informed us as to which executive officers will be retained in their positions after the merger and which executive officers will be terminated, although it is presently contemplated that most of our executive officers will be retained. If the executive's employment were terminated immediately following the merger and/or the executive receives the stay bonus, the estimated lump sum cash termination payments that would be payable under the above agreements to each executive would be approximately: Mr. Anderson, $1,370,000; Mr. Boutin, $765,000; Mr. Carlson, $765,000; Mr. Dickey, $1,121,000; and Mr. Larson, $1,121,000.

Payment for Stock Options and Restricted Stock.

Our executive officers owned stock options to purchase an aggregate of 365,000 shares of our common stock and our executive officers and directors held 542,000 unvested shares of restricted stock, as of the record date. Our executive officers and directors own no warrants to purchase shares of our common stock. All of the unvested awards of restricted stock owned by our executive officers and directors will vest as a result of the merger. At the effective time of the merger, all outstanding stock options held by our executive officers will be canceled. In consideration for the cancellation, the executive officer will have the right to receive a cash payment with respect to each option equal to the product of (1) the excess, if any, of the merger consideration over the per share exercise price of the option, multiplied by (2) the aggregate number of shares of common stock then subject to the option. Payment of this cash consideration will be subject to all required tax withholdings. The executive

officers and directors will receive payment of the merger consideration for all of their restricted stock in the same fashion as payment of the merger consideration is made for other outstanding shares of TransMontaigne's common stock.

The following table lists the payments that we will make upon completion of the merger to each of our executive officers and directors that are attributable to stock options and unvested shares of restricted stock, which amounts do not reflect tax withholdings we are required to collect.

		Vested Options			Restricted Stock that will vest as a result of the Merger			Totals
		Shares	Value		Shares	Value		Shares	Value
Executive Officers:
	Donald H. Anderson	130,000	$	865,000	121,000	$	1,361,250	251,000	$	2,226,250

Vesting of Restricted Partnership Units

In addition, unvested restricted common limited partnership units, which we refer to as the "common units," awarded to our executive officers and directors under the TransMontaigne Partners' equity incentive plan will vest as a result of the merger. Although vesting is accelerated, these common units, like all other common units of TransMontaigne Partners, are not affected by the merger and have no right to receive the merger consideration. Under the terms of the TransMontaigne Partners' equity incentive plan, the number of restricted common units that will vest upon consummation of the merger for each executive officer of TransMontaigne is: Mr. Anderson, 13,250; Mr. Boutin, 8,875; Mr. Carlson, 8,875; Mr. Dickey, 13,250; and Mr. Larson, 13,250.

Continued Benefits

In connection with the merger, our employees immediately prior to the effective time of the merger will be provided benefits (other than equity or equity-based compensation plans) until twelve months after the effective time that are, in the aggregate, no less favorable than the benefits provided under our benefit plans in which such employees participated immediately prior to the effective time. All of our executive officers currently participate in our benefit plans, which include medical, dental and vision coverage, vacation, prescription drug benefits, voluntary term life insurance, accidental death and dismemberment insurance, long term disability insurance, flexible spending accounts, educational assistance, extended sick leave and business travel accident insurance.

Indemnification of Directors and Officers

Pursuant to the merger agreement, the certificate of incorporation of the surviving corporation will contain provisions no less favorable with respect to indemnification and advancement of expenses for matters occurring prior to the effective time of the merger than those set forth in our certificate of incorporation as in effect on May 22, 2006.

The merger agreement also provides that SemGroup Subsidiary and the surviving corporation will maintain in effect for six years from the effective time of the merger directors' and officers' liability

insurance with respect to acts or omissions occurring prior to the effective time of the merger covering each of the indemnified parties described above, on terms with respect to coverage, amount and advancement of expenses no less favorable than those provided in the directors' and officers' insurance maintained by TransMontaigne as of May 22, 2006. However, in no event will the surviving corporation or SemGroup Subsidiary be required to expend an amount per year greater than 250% of the annual premium in effect for TransMontaigne for such policies as of May 22, 2006. If the amount of the annual premium necessary to maintain or procure such insurance coverage exceeds such maximum amount, the surviving corporation will maintain or procure, for such six year period, directors' and officers' insurance providing the greatest coverage then available for an annual premium equal to that maximum amount. SemGroup Subsidiary may satisfy its obligations by purchasing a "tail" insurance policy with a claim period of at least six years from the effective time.

In addition, SemGroup Subsidiary and the surviving corporation will, to the fullest extent permitted by applicable law, indemnify and hold harmless the indemnified parties identified in the first paragraph of this section against all reasonable expenses, losses or amounts paid in settlement in respect of any threatened, pending or completed claim or proceeding arising out of the fact that such person is or was a director or officer of TransMontaigne, or arising out of acts or omissions occurring on or prior to the effective time of the merger.

In the event of any consolidation, merger or transfer of all or substantially all of the assets of SemGroup Subsidiary or the surviving corporation, SemGroup Subsidiary and the surviving corporation will be required to make proper provision so that any successor of SemGroup Subsidiary or the surviving corporation will assume the obligations set forth above.

The Merger

This section of the proxy statement describes material aspects of the proposed merger. Although we believe that the description covers the material terms of the merger, this summary may not contain all of the information that is important to you. You are encouraged to carefully read this entire proxy statement and the other documents we refer you to for a more complete understanding of the merger. In addition, we incorporate important business and financial information into this proxy statement by reference. You may obtain the information incorporated by reference into this proxy statement without charge by following the instructions in the section entitled "Where Stockholders Can Find More Information" that begins on page [ ].

Effective Time of Merger

If the merger agreement is approved by the requisite vote of stockholders and the other conditions to the merger are satisfied, or waived to the extent permitted pursuant to the merger agreement, the merger will be consummated and become effective at the time the certificate of merger is filed with the Secretary of State of the State of Delaware or at any later time as we, SemGroup Subsidiary and Merger Co agree upon and specify in the certificate of merger. If our stockholders adopt the merger agreement, the parties intend to complete the merger as soon as practicable thereafter. The parties to the merger agreement expect to complete the merger during the third calendar quarter of 2006. Because the merger is subject to various conditions, including conditions that are not within the exclusive control of TransMontaigne and SemGroup, the exact timing of the merger cannot be determined. See "The Merger—Regulatory Matters" beginning on page [ ].

We or SemGroup Subsidiary may terminate the merger agreement prior to the effective time of the merger in specified circumstances, whether before or after the adoption of the merger agreement by stockholders. Additional details on the termination of the merger agreement are described in "The Merger Agreement—Termination" below.

At the effective time of the merger, SemGroup Subsidiary will own 100% of our equity securities. In addition:

•: our stockholders will no longer have any ownership interest in, or be a stockholder of, TransMontaigne;
•: SemGroup Subsidiary, and not our stockholders, will benefit from any increases or decreases in our value after the effective time; and
•: our common stock will no longer be quoted on the New York Stock Exchange.

Payment of Merger Consideration and Surrender of Stock Certificates

SemGroup Subsidiary has designated Mellon Investor Services LLC as the paying agent to make the cash payments contemplated by the merger agreement. Prior to the effective time of the merger, SemGroup will deposit, or cause to be deposited, in trust with the paying agent funds in an aggregate amount sufficient to make the cash payments described above to all stockholders in respect of their shares of our common stock or preferred stock.

No later than 10 days after the effective time, SemGroup Subsidiary will cause the paying agent to send you a letter of transmittal and instructions advising you how to surrender your certificates in exchange for the merger consideration. You should not forward your stock certificates to the paying agent without a letter of transmittal, and you should not return your stock certificates with the enclosed proxy.

The paying agent will pay you your merger consideration and your certificates will be cancelled after you have (1) surrendered your certificates to the paying agent, together with such letter of transmittal and (2) provided to the paying agent any other items specified by the letter of transmittal. Any stockholder that has not complied with clauses (1) and (2) set forth above six months after the effective time of the merger shall thereafter look solely to SemGroup Subsidiary with respect to the merger consideration payable or issuable upon due surrender of their certificates. Interest will not be paid or accrue in respect of cash payments of merger consideration. The paying agent shall be entitled to reduce the amount of any merger consideration paid to you by any applicable withholding taxes.

Morgan Stanley will be entitled to receive payment pursuant to the terms of the warrant to purchase our common stock granted on November 23, 2004.

In the event of a transfer of ownership of shares of our stock that is not registered in our transfer records, a check for the cash that such holder has the right to receive in respect of such holder's shares of stock formerly represented by such certificate may be issued to a transferee if the certificate representing such shares is presented to the paying agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid.

If any certificate has been lost, stolen or destroyed, 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 TransMontaigne, the posting by such person of a bond, in such reasonable amount as we may direct, as indemnity against any claim that may be made against it with respect to such certificate, the paying agent will issue in exchange for such lost, stolen or destroyed certificate, the merger consideration, without any interest thereon.

At the effective time of the merger, we will close our stock transfer books. After that time, if you present common stock or preferred stock certificates to us, we will exchange them for cash as described in this section.

After the merger, you will cease to have any rights as a stockholder of TransMontaigne, other than the right to surrender your certificate in exchange for payment of the merger consideration.

Regulatory Matters

The HSR Act and the rules and regulations promulgated thereunder require that SemGroup and TransMontaigne file notification and report forms with respect to the merger and related transactions with the Antitrust Division of the U.S. Department of Justice and the U.S. Federal Trade Commission, which we refer to as the "FTC". The parties thereafter are required to observe a waiting period before completing the merger. On April 21, 2006, TransMontaigne and SemGroup filed the necessary forms with the Department of Justice and the Federal Trade Commission. The initial waiting period was scheduled to expire at 11:59 p.m. Eastern Daylight Time on May 22, 2006; however, on that date, the FTC issued a formal written request for the parties to supply additional information and documentary material, which we refer to as a "second request." The second request extends and expands both the scope and the time frame covered by the FTC's previous information request to which we responded in full in our original filing with the FTC. The second request seeks detailed information with respect to fourteen (14) terminal areas located in the Southeast and Midwest in which both we and Magellan Midstream Partners, L.P. ("Magellan") each own terminals. The Magellan terminals are included in the second request apparently due to the cross-ownership interests of the Carlyle/Riverstone Group in both SemGroup and Magellan. As a result of the second request, the waiting period under the HSR Act will expire 30 days from the date the parties provide the requested additional information and documentation to the FTC. We currently estimate that it may take us up to three months to compile the supplemental information requested by the FTC. Alternatively, the FTC's concerns may be resolved earlier through negotiations. The Department of Justice or the FTC, as well as a state or private person, may challenge the merger at any time before or after its completion.

Except for the expiration or termination of the waiting period under the HSR Act, we are unaware of any material federal, state or local regulatory requirements or approvals required for the completion of the merger.

Anticipated Accounting Treatment

The merger is intended to be accounted for by SemGroup Subsidiary as a purchase under generally accepted accounting principles in the United States of America. Accordingly, it is expected that SemGroup Subsidiary's carrying value in the assets and liabilities of TransMontaigne for accounting purposes will be adjusted to fair value upon completion of the merger.

Material U.S. Federal Income Tax Consequences

The following is a discussion of the material U.S. federal income tax consequences of the merger to holders of TransMontaigne common stock and TransMontaigne preferred stock. This discussion is based upon the Code, the Treasury Regulations promulgated thereunder, and judicial and administrative rulings and decisions in effect on the date hereof. These authorities may change at any time, possibly retroactively, and any such change could affect the continuing validity of this discussion. No ruling from the Internal Revenue Service (the "IRS") has been requested with respect to the U.S. federal income tax consequences described herein and accordingly, there can be no assurance that the IRS will agree with the discussion herein. In addition, this discussion does not address any tax consequences arising under the laws of any state, locality or foreign jurisdiction, and accordingly, is not a comprehensive description of all of the tax consequences that may be relevant to any particular holder of TransMontaigne stock.

This discussion assumes that holders hold their shares of our common stock and preferred stock as capital assets and does not address the tax consequences that may be relevant to a particular stockholder subject to special treatment under U.S. federal income tax law, including but not limited to:

•: foreign persons;

•: financial institutions;
•: tax-exempt organizations;
•: insurance companies;
•: traders in securities that elect mark-to-market;
•: dealers in securities or foreign currencies;
•: persons who received their stock of TransMontaigne through the exercise of employee stock options or otherwise as compensation;
•: persons who hold shares of stock of TransMontaigne as part of a hedge, straddle or conversion transaction;
•: persons who exercise their appraisal rights under Delaware law; and
•: persons who have an interest in, or are affiliated with, SemGroup, either directly, indirectly or by attribution after the merger.

Characterization of the Merger

For U.S. federal income tax purposes, the merger of Merger Co with and into TransMontaigne will be treated as a taxable transaction to holders of TransMontaigne stock and will not be treated as a taxable transaction to TransMontaigne.

A holder of TransMontaigne stock will recognize capital gain or loss equal to the difference between the amount of cash received in the merger and such holder's adjusted tax basis in such stock. Such gain or loss will be long-term capital gain or loss if at the time of the merger the holder had a holding period in its TransMontaigne stock of more than one year. Gain or loss must be determined separately for each block of TransMontaigne stock (i.e., stock acquired at the same cost in a single transaction).

Information Reporting and Backup Withholding

Certain noncorporate holders of TransMontaigne stock may be subject to information reporting and backup withholding, at applicable rates (currently 28%), on cash payments received pursuant to the merger. Backup withholding will not apply, however, to a holder who furnishes a correct taxpayer identification number and certifies that the holder is not subject to backup withholding on IRS Form W-9 or a substantially similar form or is otherwise exempt from backup withholding. If a holder does not provide its correct taxpayer identification number or fails to provide the certification described above, the IRS may impose a penalty on the holder, and amounts received by the holder pursuant to the merger may be subject to backup withholding. Amounts withheld, if any, are generally not an additional tax and may be refunded or credited against the holder's U.S. federal income tax liability, provided that the holder furnishes the required information to the IRS.

ALTHOUGH THE FOREGOING ARE THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES GENERALLY APPLICABLE TO THE MERGER, THIS DISCUSSION DOES NOT ADDRESS EVERY U.S. FEDERAL INCOME TAX ISSUE WHICH MAY BE APPLICABLE TO A PARTICULAR STOCKHOLDER. EACH STOCKHOLDER IS ENCOURAGED TO CONSULT HIS OR HER OWN TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES TO SUCH STOCKHOLDER, IN LIGHT OF HIS OR HER PARTICULAR CIRCUMSTANCES, OF THE DISPOSITION OF TRANSMONTAIGNE COMMON STOCK OR TRANSMONTAIGNE PREFERRED STOCK PURSUANT TO THE MERGER.

Appraisal Rights

Under Delaware law, you are entitled to appraisal rights in connection with the merger. All references in this summary of appraisal rights to a "stockholder" or "holders of shares of stock" are to the record holder or holders of those shares.

If the merger is consummated, dissenting stockholders who follow the procedures described below within the appropriate time periods will be entitled to have their shares of stock appraised by a court and to receive the "fair value" of such shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, in cash as determined by the Delaware Court of Chancery, together with a fair rate of interest, if any, as determined by the court, in lieu of the consideration that such stockholder would otherwise be entitled to receive pursuant to the merger agreement. These rights are known as appraisal rights.

The discussion of the provisions set forth below is not a complete summary regarding your appraisal rights under Delaware law and is qualified in its entirety by reference to the text of the relevant provisions of Delaware law, which are attached to this proxy statement as Appendix C. Stockholders intending to exercise appraisal rights should carefully review Appendix C. Failure to follow precisely any of the statutory procedures set forth in Appendix C may result in the termination or waiver of these rights.

Under Section 262 of the DGCL, if a merger is to be submitted for approval at a meeting of stockholders, as in the case of the merger agreement, the corporation, not less than 20 days prior to the meeting, must notify each of its stockholders if appraisal rights are available and include in the notice a copy of Section 262 of the DGCL. This proxy statement constitutes the required notice, and we attach a copy of Section 262 of the DGCL to this proxy statement as Appendix C.

In order to exercise your appraisal rights effectively, you must satisfy each of the following primary requirements:

•: You must hold shares in TransMontaigne as of the date you make your demand for appraisal rights and continue to hold shares in TransMontaigne through the effective time of the merger.
•: You must deliver to TransMontaigne a written notice of your demand of payment of the fair value for your shares prior to the taking of the vote at the special meeting.
•: You must not have voted in favor of adoption of the merger agreement.
•: You must file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares within 120 days after the effective time of the merger if TransMontaigne or another stockholder has not filed such a petition.

If you fail to comply with any of the above conditions or otherwise fail to comply with the requirements of Section 262 of the DGCL, you will have no appraisal rights with respect to your shares.

Neither voting (in person or by proxy) against, abstaining from voting on or failing to vote on the proposal to adopt the merger agreement will constitute a written demand for appraisal within the meaning of Section 262 of the DGCL. The written demand for appraisal must be in addition to and separate from any proxy or vote.

The address for purposes of making an appraisal demand is:

1670 Broadway, Suite 3100
Denver, Colorado 80202
Attention: Secretary

Within 120 days after the effective time of the merger, any stockholder who has satisfied the requirements of Section 262 may deliver to us a written demand for a statement listing the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares.

A person having a beneficial interest in shares of TransMontaigne stock that are held of record as of the record date in the name of another person, such as a broker, fiduciary, depositary or other nominee, must act promptly to cause the record holder to follow the steps summarized herein properly and in a timely manner to perfect their appraisal rights. If the shares of TransMontaigne stock are owned of record by a person other than the beneficial owner, including a broker, fiduciary (such as a trustee, guardian or custodian), depositary or other nominee, such demand must be executed by or for the record owner. If the shares of TransMontaigne stock are owned of record by more than one person, as in a joint tenancy or tenancy in common, such demand must be executed by or for all joint owners. An authorized agent, including an agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner and expressly disclose the fact that, in exercising the demand, such person is acting as agent for the record owner. If a stockholder holds shares of TransMontaigne stock through a bank or broker who in turn holds the shares through a central securities depository nominee such as Cede & Co., a demand for appraisal of such shares must be made by or on behalf of the depository nominee and must identify the depository nominee as record holder.

Within 120 days after the effective time of the merger (but not thereafter), either TransMontaigne or any stockholder who has complied with the required conditions of Section 262 and who is otherwise entitled to appraisal rights may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of his or her shares. We have no present intention to file such a petition if demand for appraisal is made and stockholders seeking to exercise appraisal rights should not assume that we will file such a petition or that we will initiate any negotiations with respect to the fair value of such shares. Accordingly, holders of TransMontaigne stock who desire to have their shares appraised should initiate any petitions necessary to properly demand their appraisal rights within the time periods and in the manner prescribed in Section 262.

Upon the filing of any petition by a stockholder in accordance with Section 262, service of a copy must be made upon TransMontaigne, which must, within 20 days after service, file in the office of the Register in Chancery in which the petition was filed, a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by TransMontaigne. If a petition is filed by TransMontaigne, the petition must be accompanied by the verified list. The Register in Chancery, if so ordered by the court, will give notice of the time and place fixed for the hearing of such petition by registered or certified mail to TransMontaigne and to the stockholders shown on the list at the addresses therein stated, and notice will also be given by publishing a notice at least one week before the day of the hearing in a newspaper of general circulation published in the City of Wilmington, Delaware, or such publication as the court deems advisable. The forms of the notices by mail and by publication must be approved by the court, and the costs thereof will be borne by us.

If a petition for an appraisal is filed in a timely fashion, after a hearing on the petition, the court will determine which stockholders are entitled to appraisal rights and will appraise the shares owned by these stockholders, determining the fair value of such shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. The court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the court may dismiss the proceedings as to such stockholder.

We do not anticipate offering more than the merger consideration to any stockholder exercising appraisal rights and reserve the right to assert, in any appraisal proceeding, that, for purposes of Section 262, the "fair value" of a share of TransMontaigne stock is less than the merger consideration that would otherwise be received for that stock. In determining "fair value", the court is required to take into account all relevant factors. In Weinberger v. UOP, Inc. the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that "proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court" should be considered and that "[f]air price obviously requires consideration of all relevant factors involving the value of a company." The Delaware Supreme Court has stated that in making this determination of fair value the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts which could be ascertained as of the date of the merger which throw any light on future prospects of the merged corporation. Section 262 provides that fair value is to be "exclusive of any element of value arising from the accomplishment or expectation of the merger." In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a "narrow exclusion [that] does not encompass known elements of value," but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Delaware Supreme Court construed Section 262 to mean that "elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered."

In light of the case law interpretations noted above, stockholders considering seeking appraisal of their shares should note that the fair value of their shares determined under Section 262 could be more, the same or less than the consideration they would receive pursuant to the merger agreement if they did not seek appraisal of their shares. The costs of the appraisal proceeding may be determined by the court and assessed against the parties as the court deems equitable under the circumstances. Upon application of a dissenting stockholder, the court may order that all or a portion of the expenses incurred by any dissenting stockholder in connection with the appraisal proceeding, including reasonable attorneys' fees and the fees and expenses of experts, be charged pro rata against the value of all shares entitled to appraisal. In the absence of a determination or assessment, each party bears his, her or its own expenses.

Any stockholder who has duly demanded appraisal in compliance with Section 262 will not, after the effective time of the merger, be entitled to vote for any purpose the shares subject to the appraisal demand or to receive payment of dividends or other distributions on such shares, except for dividends or distributions declared by our board of directors and payable to stockholders of record at a date prior to the effective time of the merger.

At any time within 60 days after the effective time of the merger, any stockholder will have the right to withdraw his demand for appraisal and to accept the terms offered in the merger agreement. After this period, a stockholder may withdraw his demand for appraisal and receive payment for his shares as provided in the merger agreement only with the consent of TransMontaigne. In addition, no petition timely filed in the court demanding appraisal may be dismissed as to any stockholder without the approval of the court, which approval may be conditioned upon such terms as the court deems just. If no petition for appraisal is filed with the court within 120 days after the effective time of the merger, stockholders' rights to appraisal (if available) will cease and all stockholders will be entitled to receive the consideration offered pursuant to the merger agreement. Inasmuch as we have no obligation to file such a petition, any stockholder who desires a petition to be filed is advised to file it on a timely basis.

Failure by any stockholder to comply fully with the procedures described above and set forth in Appendix C to this proxy statement may result in termination or waiver of a stockholder's appraisal rights.

Conduct of Our Business if the Merger is Not Consummated

If we do not consummate the merger, our board of directors expects to seek to retain our current management team, although there can be no assurance it will be successful in doing so. There are no plans in such circumstances to operate our business in a manner substantially different than presently operated.

The Merger Agreement

This section of the proxy statement summarizes the material provisions of the merger agreement. The following summary is qualified entirely by reference to the complete text of the merger agreement, a copy of which is attached as Appendix A to this proxy statement and incorporated into this proxy statement by reference. We encourage you to read the merger agreement carefully and in its entirety.

We have attached the merger agreement to this proxy statement to provide you with information regarding its terms. The merger agreement is not intended to be a source of any other information about the parties.

The representations, warranties and covenants made by the parties in the merger agreement and discussed below, are qualified by information in the confidential disclosure schedules we provided to SemGroup in connection with the execution of the merger agreement, and are otherwise subject to important limitations agreed to by the parties to the merger agreement in connection with negotiating its terms. Certain representations and warranties may have been used by the parties to allocate risks among the respective parties to the merger agreement, including where the parties do not have complete knowledge of all facts, instead of establishing such matters as facts. Furthermore, the representations and warranties may be subject to standards of materiality applicable to the contracting parties, which may be different from any particular investor's standards of what constitutes important information. These representations and warranties may or may not have been accurate as of any specific date and do not purport to be accurate as of the date this proxy statement is distributed to you. Accordingly, representations and warranties should not be relied upon as statements of factual information. You are not third-party beneficiaries under the merger agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of TransMontaigne or its subsidiaries. None of the representations and warranties contained in the merger agreement will have any legal effect among the parties to the merger agreement after the closing of the merger.

General

Upon the terms and subject to the conditions set forth in the merger agreement and in accordance with the DGCL, Merger Co shall be merged with and into TransMontaigne. The separate corporate existence of Merger Co shall cease and TransMontaigne shall continue as the surviving corporation, wholly owned by SemGroup.

At the effective time of the merger, our certificate of incorporation and by-laws will be amended in their entirety as set forth in the merger agreement, and the same shall be the certificate of incorporation and by-laws, respectively, of the surviving corporation until thereafter amended in accordance with their terms and applicable law.

The directors of Merger Co immediately prior to the effective time of the merger will be the initial directors of the surviving corporation and the officers of TransMontaigne immediately prior to the effective time shall be the initial officers of the surviving corporation, in each case to hold office in accordance with the certificate of incorporation and bylaws of the surviving corporation.

Treatment of Our Stock in the Merger

At the effective time of the merger, by virtue of the merger agreement and without any additional action on the part of our stockholders:

•: each issued and outstanding share of our common stock will be cancelled and will be converted automatically into the right to receive $11.25 in cash;
•: each issued and outstanding share of our preferred stock will automatically be converted into the right to receive $1,704.55 or, at the holder's election, the right to receive $1,000 plus all accrued but unpaid dividends thereon through the redemption date indicated in the certificate of designations setting forth the rights, privileges and preferences of the preferred stock;
•: each share of our common stock and preferred stock held in treasury and each share of common and preferred stock held by SemGroup, Merger Co or any direct or indirect wholly owned subsidiary of SemGroup or Merger Co or any direct or indirect wholly owned subsidiary of ours will be cancelled and no payment or distribution will be made with respect to such shares;
•: each share of common stock of Merger Co issued and outstanding immediately prior to the effective time of the merger will be converted into one share of common stock of the surviving corporation. Following the effective time of the merger, each certificate evidencing ownership of shares of Merger Co will evidence ownership of such shares of the surviving corporation.

At the effective time of the merger, all shares of our capital stock shall no longer be outstanding and shall be cancelled, retired and will cease to exist. Each certificate previously representing any such shares shall thereafter represent the right to receive the cash consideration described above.

We will also take all actions necessary to ensure that, at the effective time of the merger:

•: each option to purchase shares of our common stock that is outstanding immediately prior to the effective time of the merger, whether or not then exercisable, will be cancelled, and each option holder will be entitled to receive a cash payment equal to the amount by which $11.25 exceeds the exercise price of the option, multiplied by the number of shares of our common stock issuable upon exercise of the option, less all withholding taxes;
•: forfeiture restrictions in effect on outstanding shares of restricted stock shall be terminated, and each such share shall be converted into the right to receive $11.25 in cash, less all withholding taxes; and
•: the warrant to purchase shares of our common stock granted to Morgan Stanley on November 23, 2004 will no longer represent the right to receive shares of our common stock, but rather represent the right to receive cash in accordance with the terms of the warrant.

Under the terms of the merger agreement and applicable Delaware law, shares of our common stock or preferred stock that are outstanding immediately prior to the effective time and that are held by any stockholder who takes the actions specified in Section 262 of the DGCL to properly demand such stockholder's rights of appraisal, will not be converted into the right to receive the merger consideration. Such stockholders will be entitled to receive payment of the fair value of their shares in accordance with the provisions set forth under Delaware law. See "The Merger—Appraisal Rights" beginning on page [ ].

SemGroup and Merger Co have also made customary representations and warranties to us subject to, in some cases, specified exceptions and qualifications contained in the merger agreement or in the disclosure schedules delivered in connection with the merger agreement. These representations and warranties, which will not survive the effective time of the merger, relate to, among other matters:

•: their due organization, valid existence, good standing, power and authority to carry on their business;

•: their power and authority to enter into the merger agreement and to consummate the transactions contemplated by the merger agreement and the enforceability of the merger agreement against them;

•: their ownership of our common stock during the past two years.

Certain aspects of the representations and warranties of the parties are qualified by the concepts of "material adverse effect." A material adverse effect means a "TransMontaigne Partners material adverse effect" or any event, circumstance, development, change or effect that, either individually or in the aggregate, is or would be materially adverse to our business, condition, financial or otherwise, or results of operations, other than:

The merger agreement defines a "TransMontaigne Partners material adverse effect" as generally, the bankruptcy, insolvency or dissolution of TransMontaigne Partners or TransMontaigne GP, the resignation of TransMontaigne GP as the general partner of TransMontaigne Partners or the adoption of any law, or the taking of any other action, by any governmental authority that would, or would reasonably be expected to, prevent or materially hinder or delay, or materially increase the cost to consummate, any proposed sale, contribution or other transfer of assets from the SemGroup Subsidiary or TransMontaigne to TransMontaigne Partners, with certain exceptions, or the occurrence of any circumstances that would permit the removal of TransMontaigne GP as the General Partner of TransMontaigne Partners or the sale of substantially all of the assets of TransMontaigne Partners or TransMontaigne GP.

Conduct of Business by TransMontaigne Before the Merger

The merger agreement provides that, between the date of the merger agreement and the effective time of the merger, unless SemGroup Subsidiary gives its prior written consent, we will:

•: conduct our business only in the ordinary course and in a manner consistent with past practice;
•: use our reasonable best efforts consistent with past practice to preserve our business organization and to maintain our assets and properties in good repair and condition; and
•: use our reasonable best efforts consistent with past practice to keep available the services of our present officers and employees and to preserve the current relationships with our customers, suppliers and other parties with which we have material business relations.

Covenants of TransMontaigne

The merger agreement also provides specific covenants relating to our activities from the date of the merger agreement until the effective time of the merger. These covenants provide, subject to certain exceptions, that we will not, and will not permit any of our subsidiaries to, without SemGroup Subsidiary's prior written consent:

•: take any action that would likely prevent or delay the closing or that would have a material adverse effect; or
•: take, or permit any action to be taken, that would result in a breach of any representation or warranty in the merger agreement.

Acquisition Proposals

The merger agreement prohibits us from, directly or indirectly:

•

soliciting, initiating or knowingly encouraging any inquiries regarding, or the making of any proposal or offer that constitutes, or could lead to any acquisition proposal. An acquisition proposal is defined as:

•: any proposal or offer from any third party relating to any acquisition of 20% or more of our assets,
•: 20% or more of any class of our equity securities, or
•: any merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving TransMontaigne, excluding the transactions contemplated by the merger agreement.

•

change or modify the approval or recommendation by our board of directors with respect to the adoption of the merger agreement (referred to as a "change in board recommendation"), subject to certain exceptions;

•

have any discussions or participate in any negotiations regarding an acquisition proposal, or execute or enter into any agreement, understanding or arrangement with respect to an acquisition proposal;

•

approve or recommend or propose to approve or recommend an acquisition proposal or any agreement, understanding or arrangement relating to an acquisition proposal;

•

take any action to exempt any third party from the restrictions on business combinations contained Delaware law; or

•

waive, terminate, modify or fail to enforce any provisions of any standstill agreement or similar obligation into which any third party has entered.

However, if, prior to the adoption of the merger agreement by our stockholders, we receive an acquisition proposal by any third party and our board of directors determines in good faith, after consultation with our legal counsel and financial advisor, that the acquisition proposal could reasonably

lead to a superior proposal and that the failure to participate in discussions with the third party regarding the acquisition proposal could result in a breach in our board of director's fiduciary obligations or any applicable law, we may, subject to certain restrictions, furnish non-public information to the third party making the acquisition proposal (provided the third party has entered into a mutual non-disclosure agreement with us on terms that are no less favorable to us than those set forth in our mutual non-disclosure agreements with SemGroup) and participate in discussions and negotiations regarding such acquisition proposal. We may not enter into any confidentiality agreements with any third party which prohibits us from providing such information to SemGroup Subsidiary.

We must advise SemGroup Subsidiary within one business day of our receipt of any acquisition proposal or any inquiry that could reasonably be expected to lead to an acquisition proposal. The notification must specify the material terms and conditions of the acquisition proposal, identify the party making the acquisition proposal or inquiry, include a copy of all written materials provided to us in connection with the acquisition proposal and provide SemGroup Subsidiary with a copy of any information provided by us to the third party that has not previously been provided to SemGroup Subsidiary. Similarly, we must notify SemGroup Subsidiary of any material modifications to the terms of the acquisition proposal and provide to SemGroup Subsidiary all written materials subsequently provided to or by us in connection with the acquisition proposal.

As used in the merger agreement a "superior proposal" means any written acquisition proposal that relates to an acquisition by a third party of either (1) more than 50% of our outstanding shares of preferred and common stock pursuant to a tender offer, merger or otherwise or (2) more than 50% of our consolidated assets, and is on terms that,

•: our board of directors determines in good faith (after consultation with our financial advisor) are more favorable to our stockholders from a financial point of view than those provided in the merger agreement, and
•: our board of directors determines in good faith (after consultation with a financial advisor and its outside legal counsel) is reasonably capable of being consummated.

Other Obligations of the Parties

SemGroup Subsidiary and Merger Co have also undertaken certain obligations and responsibilities under the merger agreement including, but not limited to, the covenants described below.

Directors' and Officers' Indemnification and Insurance

The charter documents of the surviving corporation and its subsidiaries will contain provisions providing for indemnification of and advancement of expenses to directors and officers no less favorable to the officers and directors than those set forth in our charter documents (or the charter documents of the relevant subsidiary) as of May 22, 2006, for six years after the effective time of the merger. Similarly, the surviving corporation will, with certain exceptions, either obtain a pre-paid directors' and officers' liability insurance "tail" policy with a claims period of at least six years from the effective time of the merger and a scope at least as favorable as our existing policies, or maintain our existing officers' and directors' liability insurance policies.

Employee Benefits Matters

For a period of one year after the effective time of the merger, SemGroup Subsidiary will honor the terms of all employment agreements and pay or provide the benefits required thereunder in accordance with their terms and will provide salary, discretionary bonus (excluding equity or equity based incentive awards) and employee benefits that are no less favorable, in the aggregate, than those provided to our employees immediately prior to the effective time of the merger.

Following the effective time of the merger, our employees will, to the extent permitted by applicable law, receive credit for years of service accrued or deemed accrued prior to the effective time of the merger for all purposes under any employee benefit plan, program or arrangement established or maintained by SemGroup Subsidiary, the surviving corporation or any of their respective subsidiaries.

In addition to the above covenants, the parties have undertaken certain additional obligations and responsibilities under the merger agreement including, but not limited to, the covenants described below.

Financing

The merger agreement contains several covenants relating to the respective obligations of each of SemGroup Subsidiary, Merger Co and TransMontaigne with respect to the financing necessary for Merger Co to consummate the merger and the terms of such financing. With respect to our obligations to cooperate with SemGroup Subsidiary in obtaining the financing, the merger agreement provides that:

•: we will cooperate and otherwise take such action as may be reasonably requested by SemGroup Subsidiary; and
•: SemGroup Subsidiary will reimburse us for all reasonable out-of-pocket costs incurred by us in connection with such cooperation.

Further Action; Reasonable Best Efforts; Notice of Certain Events

The merger agreement provides that each of the parties will use its reasonable best efforts to:

•: effect the consummation of the merger as soon as practicable;
•: take all actions necessary to comply promptly with all legal requirements that may be imposed on it with respect to the merger and shall promptly cooperate with and furnish information to each other in connection with any requirements imposed upon any of them or any of their respective subsidiaries in connection with the merger;
•: obtain any consent, authorization, order or approval of, or any exemption by, any governmental authority or other public or private third party required to be obtained or made by the applicable party in connection with the merger;
•: redeem or otherwise amend the terms of our notes;
•: cause the aggregate merger consideration to be deposited with the paying agent contemporaneously with the merger closing; and
•: notify each other party to the merger agreement of any event, circumstance or condition of which a party becomes aware that could reasonably be expected to constitute or give rise to a material breach of any representation or warranty, covenant or condition contained in the merger agreement.

Hart-Scott-Rodino Filing

In addition, each of the parties agreed to use its reasonable best efforts to make the appropriate filings required by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, referred to as the "HSR Act," with respect to the transactions contemplated by the merger agreement and to supply any additional information and documentary material that may be requested pursuant to the HSR Act.

In the event a formal, written second request for documentation or information is issued to the parties under the HSR Act, which occurred on May 22, 2006, the expiration date of the merger agreement will automatically be extended until December 31, 2006 and the parties have agreed to:

•: promptly take any or all actions necessary to eliminate any concerns on the part of any governmental authority with jurisdiction over the enforcement of any applicable antitrust law regarding the legality of the merger under any antitrust law;
•: use their reasonable best efforts to prevent the entry in a judicial or administrative proceeding of any permanent or preliminary injunction or other order that would make consummation of the merger unlawful or that would prevent or delay such consummation;
•: in the event that such an injunction or order has been issued in such a proceeding, take any and all steps necessary to vacate, modify or suspend such injunction or order so as to permit such consummation on a schedule as close as possible to that contemplated by the merger agreement; and
•: take all other actions and do all other things necessary and proper to avoid or eliminate each and every impediment under any antitrust law that may be asserted by any government antitrust authority or any other party to the consummation of the merger.

However, the parties shall not be required to agree to make any of the above actions, if to do so would, in the reasonable, good faith judgment of the management committee of the general partner of SemGroup, have a material adverse effect upon the business plans of SemGroup for the conduct of the business of TransMontaigne, TransMontaigne Partners and/or SemGroup (or any affiliate of each) after the closing taken as a whole. For clarity, in order for a material adverse effect to be deemed to occur in this instance, the above actions would have to result in a minimum financial impact in excess of $50 million. Upon a final determination by the government antitrust authority that taking or agreeing to take any of the actions set forth in this paragraph is required to consummate the merger, SemGroup Subsidiary shall be entitled to terminate the merger agreement.

Notes

It is a condition to closing the merger that provision shall have been made with respect to our notes to either redeem the notes, or amend their terms to permit our notes to remain outstanding following the effective time of the merger. Under the terms of the merger agreement, at the written request of SemGroup, we agreed to commence a tender offer and consent solicitation with respect to any or all of our notes in accordance with the written terms and conditions provided by SemGroup and applicable law. SemGroup agreed to reimburse us for any reasonable out-of-pocket costs, fees and expenses and will indemnify our representatives for any other liabilities incurred in connection with the tender offer and consent solicitation.

Instead of requesting us to commence a tender offer, on April 3, 2006, Merger Co commenced a tender offer for our notes together with a solicitation of consents from the noteholders to amend the indenture relating to our notes to, among other changes, essentially eliminate all covenants other than the obligation to pay principal and interest on our notes. The purchase price for our notes, which is estimated to be approximately $1,050 per $1,000 principal amount of notes, will be determined ten days in advance of the date of purchase of our notes based upon a formula set forth in Merger Co's offer to purchase. In addition to the purchase price, Merger Co agreed to pay a consent fee of $30 per each $1,000 principal amount of notes validly tendered together with consents on or before the "consent date" of April 17, 2006. On April 18, 2006 Merger Co announced that it had received valid tenders together with consents from the holders of $196.6 million out of $200 million of notes outstanding. As of the date of this proxy statement, Merger Co has established , 2006 as the expiration date of its tender offer, which date may be extended from time to time at Merger Co's election.

We have not participated in, and take no responsibility for, Merger Co's offer and our board of directors has not made any determination as to whether the offer is fair to or in the best interests of the holders of our notes. Accordingly, upon the recommendation of our board of directors, which has reviewed the principal terms of the tender offer, we are expressing no opinion and remain neutral with respect to whether holders of our notes should accept or reject the tender offer.

The obligations of SemGroup Subsidiary and Merger Co to consummate the merger are further subject to the satisfaction or waiver in writing, on or prior to the closing date, of the following additional conditions:

•: our representations and warranties are true and correct in all respects as of the closing date as though made on and as of such date (except to the extent that any such representation and

warranty expressly speaks as of an earlier date, in which case such representation and warranty shall be true and correct as of such earlier date and to the extent of any change resulting from our compliance with, or actions authorized by the merger agreement); provided, however, that this condition will be satisfied, unless the failure of such representations and warranties to be true and correct, would reasonably be expected to have a material adverse effect on us, except for our representations and warranties regarding our capitalization and authority to enter into the merger agreement, which are required to be true and correct in all respects;

•: Merger Co shall have performed or complied in all material respects with all agreements and covenants required by the merger agreement to be performed or complied with by it on or prior to the effective time of the merger;

The merger agreement may be terminated and the merger abandoned at any time prior to the effective time of the merger by our board of directors or SemGroup, as applicable, whether before or

after our stockholders have approved the merger agreement at the special meeting of stockholders, under the following circumstances:

•: by the mutual agreement of SemGroup Subsidiary and us;
•: by either SemGroup Subsidiary or us if:
•: the effective time of the merger shall not have occurred on or before the merger expiration date which has been extended from July 31, 2006 to December 31, 2006 as a result of the second request from the FTC;
•: a final and non-appealable order or ruling prevents or prohibits consummation of the merger;
•: by SemGroup Subsidiary if any of our representations and warranties contained in the merger agreement are or become untrue or inaccurate or there has been a breach on the part of TransMontaigne of any of its covenants or agreements contained in the merger agreement and such breach has not been, or cannot be, cured within 30 days after notice;
•: by us, if any of the representations and warranties of either SemGroup Subsidiary or Merger Co contained in the merger agreement are or become untrue or inaccurate or there has been a breach on the part of either SemGroup Subsidiary or Merger Co of any of its covenants or agreements contained in the merger agreement and such breach has not been, or cannot be, cured within 30 days after notice to SemGroup Subsidiary or Merger Co;
•: by either SemGroup Subsidiary or us if our stockholders fail to adopt the merger agreement at the special meeting of stockholders;
•: by SemGroup if our board of directors, or an independent committee of our board of directors, makes a change in the board recommendation;
•: by us following a change in board recommendation, but only if we pay the termination fee to SemGroup as a condition to such termination; or
•: by either SemGroup Subsidiary or us if a government antitrust authority has entered a final order not subject to further appeal requiring the divestiture of specified assets of either party as discussed under "Other Obligations of the Parties—Hart-Scott-Rodino Filing" on page [ ] of this proxy statement.

Fees and Expenses

Except as set forth below, all expenses incurred in connection with the merger agreement shall be paid by the party incurring such expenses, whether or not the merger is consummated. However, SemGroup Subsidiary and TransMontaigne have each agreed to pay the other party a termination fee of $15,000,000 under specified circumstances.

We have agreed to pay SemGroup Subsidiary the termination fee:

•: if either we or SemGroup Subsidiary terminates the merger agreement because our stockholders have failed to adopt the merger agreement and if, at or prior to our special meeting of stockholders, a third party has made an acquisition proposal which is not withdrawn prior to the meeting, and no later than 12 months after the termination date of the merger agreement we consummate a transaction in connection with, or otherwise enter into or submit to our stockholders for adoption an agreement with respect to, an acquisition proposal for 50% of our stock or assets, with the termination fee payable on the date such acquisition is consummated;
•: on the termination date, if SemGroup Subsidiary terminates the merger agreement within 10 days of a change in board recommendation; and
•: on the termination date, if we terminate the merger agreement following a change in board recommendation.

SemGroup Subsidiary will pay us the termination fee on the date of termination if we terminate the merger agreement following a breach on the part of either SemGroup Subsidiary or Merger Co of any of their representations and warranties or covenants contained in the merger and such breach has not been, or cannot be, cured within 30 days after notice of such breach and, at the time of termination, our representations, warranties and covenants in the merger agreement have been met sufficient to satisfy the condition precedent to SemGroup Subsidiary and Merger Co's obligation to close that relates to our representations, warranties and covenants. In addition, SemGroup Subsidiary will pay us a reverse termination fee of $10 million under the following circumstances:

•: if we or SemGroup Subsidiary terminate the merger agreement because the merger has not occurred prior to the expiration date, the mutual conditions to our obligations and the obligations of SemGroup Subsidiary to consummate the merger have been satisfied, and we have otherwise satisfied our conditions to closing; or
•: if we or SemGroup Subsidiary terminate the merger agreement because a government antitrust authority has entered a final order not subject to further appeal requiring the divestiture of specified assets of either party as discussed under "Other Obligations of the Parties—Hart-Scott-Rodino Filing" on page [ ] of this proxy statement.

The payment of the termination fee shall not limit any party's liability for damages resulting from a willful breach of the merger agreement.

Amendments and Waivers

The merger agreement may be amended only with the consent of all parties and any party may extend the time for the performance of any obligation or other act of any other party, waive any inaccuracy in the representations and warranties of any other party and waive compliance with any agreement of any other party or any condition to its own obligations contained in the merger agreement.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth information regarding the beneficial ownership as of June 1, 2006 of our stock, by class, by (i) each of our executive officers, (ii) each of our directors, (iii) each person known by us to own beneficially more than five percent of the outstanding shares of any class of our capital stock and (iv) all directors and executive officers as a group. The information set forth below is based solely upon information furnished by such individuals or contained in filings made by such beneficial owners with the Securities and Exchange Commission, which we refer to as the "SEC". Unless stated otherwise, the address for each of our executive officers and directors is 1670 Broadway, Suite 3100, Denver, CO 80202.

The numbers of shares set forth in the table below refer to beneficial ownership and are not indicative of the voting power with respect to such shares.

The calculation of the percentage of beneficial ownership is based on 49,995,599 shares of common stock outstanding as of June 1, 2006. Beneficial ownership is determined in accordance with the rules of the SEC and includes voting and investment power with respect to shares. To our knowledge, except under applicable community property laws or as otherwise indicated, the persons named in the table have sole voting and sole investment power with respect to all shares beneficially owned. Shares of common stock underlying outstanding warrants or options that are currently exercisable or exercisable within 60 days of June 1, 2006 are deemed outstanding for the purpose of computing the percentage of

beneficial ownership of the person holding those options or warrants, but are not deemed outstanding for computing the percentage of beneficial ownership of any other person.

Section 2.02 Exchange of Certificates.

(a) Paying Agent. Prior to the Effective Time, Parent shall (i) appoint a bank or trust company reasonably acceptable to the Company (the "Paying Agent"), and (ii) enter into a paying agent agreement, in form and substance reasonably acceptable to Parent and the Company, with such Paying Agent for the payment of the Merger Consideration in accordance with this Article II.

The Exchange Fund shall not be used for any other purpose. The Exchange Fund shall be invested by the Paying Agent as directed by the Parent; provided, however, that such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by Moody's Investors Service, Inc. or Standard & Poor's Corporation, respectively, or in certificates of deposit, bank repurchase agreements or banker's acceptances of commercial banks with capital exceeding $1 billion (based on the most recent financial statements of such bank which are then publicly available).

Upon surrender to the Paying Agent of a Common Certificate for cancellation, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Common Certificate shall be entitled to receive in exchange therefore the amount of cash that such holder has the right to receive in respect of the Common Shares formerly represented by such Common Certificate pursuant to

In the event of a transfer of ownership of Common Shares that is not registered in the transfer records of the Company, payment of the Common Merger Consideration may be made to a Person other than the Person in whose name the Common Certificate so surrendered is registered if the Common Certificate representing such Common Shares shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other taxes required by reason of the payment of the Common Merger Consideration to a Person other than the registered holder of such Common Certificate or establish to the reasonable satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Common Certificate shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Common Merger Consideration to which the holder of such Common Certificate is entitled pursuant to this Article II. No interest shall be paid or will accrue on any cash payable to holders of Common Certificates pursuant to the provisions of this Article II.

(c) Exchange Procedures Company Preferred Stock. As promptly as practicable after the Effective Time, but in any event within 10 days following the Effective Time, the Company shall cause the Paying Agent to mail to each Person who was, immediately prior to the Effective Time, a holder of record of the Preferred Shares entitled to receive the Preferred Merger Consideration pursuant to Section 2.01(b), the Preferred Transmittal Letter. The Preferred Transmittal Letter shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the certificates evidencing such Shares (the "Preferred Certificates" and together with the Common Certificates, the "Certificates") shall pass, only upon:

(i) surrender to the Paying Agent of (a) a Preferred Certificate, together with (b) the Preferred Transmittal Letter, duly completed and validly executed in accordance with the instructions thereto, and (c) such other documents as may be required pursuant to such instructions, including if elected by such holder in its discretion, such holder's specific request to exercise such holder's option to have the Company redeem such shares; or

(ii) surrender to the Paying Agent of (a) a Preferred Certificate for cancellation, together with (b) the Preferred Transmittal Letter, duly completed and validly executed in accordance with the instructions thereto, and (c) such other documents as may be required pursuant to such instructions.

Following compliance with the procedure described in Section 2.02(c)(i), the holder of such Preferred Certificate shall be entitled to receive in exchange therefor the Preferred Redemption Value such holder has the right to receive in respect of the Preferred Shares formerly represented by such Preferred Certificate pursuant to Section 2.01(b), and the Preferred Certificate so surrendered shall forthwith be cancelled.

Following compliance with the procedure described in Section 2.02(c)(ii), the holder of such Preferred Certificate shall be entitled to receive in exchange therefor the Preferred Conversion Value such holder has the right to receive in respect of the Preferred Shares formerly represented by such Preferred Certificate pursuant to Section 2.01(b), and the Preferred Certificate so surrendered shall forthwith be cancelled.

Section 2.02(c)(ii) shall apply to all holders of Preferred Shares entitled to receive the Preferred Merger Consideration, except solely with respect to those holders of Preferred Shares who have elected to receive the Preferred Redemption Value under, and satisfied all requirements of, Section 2.02(c)(i) of this Agreement.

In the event of a transfer of ownership of Preferred Shares that is not registered in the transfer records of the Company, payment of the Preferred Merger Consideration may be made to a Person

A-4

other than the Person in whose name the Preferred Certificate so surrendered is registered if the Preferred Certificate representing such Preferred Shares shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other taxes required by reason of the payment of the Preferred Merger Consideration to a Person other than the registered holder of such Preferred Certificate or establish to the reasonable satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02(c), each Preferred Certificate shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Preferred Merger Consideration to which the holder of such Preferred Certificate is entitled pursuant to this Article II. No interest shall be paid or will accrue on any cash payable to holders of Preferred Certificates pursuant to the provisions of this Article II.

(d) No Further Rights. From and after the Effective Time, holders of Certificates shall cease to have any rights as stockholders of the Company, except as otherwise provided herein or by Law.

(e) Exchange Fund for Dissenting Shares. Any portion of the Exchange Fund deposited with the Paying Agent pursuant to Section 2.02(a) to pay for Shares that become Dissenting Shares shall be delivered to the Parent upon demand following the filing of a petition for appraisal of the Shares with the Delaware Court of Chancery; provided, however, that Parent and the Surviving Corporation shall remain liable for payment of the Merger Consideration for such Shares held by any stockholder who shall have failed to perfect or who otherwise shall have withdrawn or lost such stockholder's rights to appraisal of such Shares under Section 262 of the DGCL ("Section 262").

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Shares for 180 days after the Effective Time shall be delivered to the Parent, upon demand, and any holders of Shares who have not theretofore complied with this Article II shall thereafter look only to the Parent and Surviving Corporation for, and Parent and the Surviving Corporation shall remain liable for, payment of their claim for the Merger Consideration; provided, however, that portion of the Exchange Fund attributable to the difference between the Preferred Conversion Value over the Preferred Redemption Value due to the election of the Redemption Option under Section 2.02(c)(i) (the "Preferred Excess Amount") shall be retained by the Parent and the holders of the Shares shall not have right or claim to such Preferred Excess Amount.

(g) No Liability. None of the Paying Agent, Parent, Merger Co or the Surviving Corporation shall be liable to any holder of Shares for any such Shares (or dividends or distributions with respect thereto), or cash properly delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(h) Withholding Rights. Each of the Paying Agent, Parent, the Surviving Corporation and Merger Co shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Shares such amounts as it is required to deduct and withhold with respect to such payment under applicable Law and pay such withholding amount over to the appropriate taxing authority. To the extent that amounts are so properly withheld by the Paying Agent, Parent, the Surviving Corporation or Merger Co, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by the Paying Agent, Parent, the Surviving Corporation or Merger Co, as the case may be.

(i) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, 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 the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim

A-5

that may be made against it with respect to such Certificate, the Paying Agent shall pay in respect of such lost, stolen or destroyed Certificate the Merger Consideration to which the holder thereof is entitled pursuant to Section 2.01(a).

Section 2.03 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Shares thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates representing Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares, except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates presented to the Paying Agent or Merger Co for any reason shall be cancelled against delivery of the Merger Consideration to which the holders thereof are entitled pursuant to Section 2.01(a).

Section 2.04 Options, Warrants and Restricted Stock.

(a) Prior to the Effective Time, the Company shall take all actions necessary to ensure that, at the Effective Time, each option then outstanding to purchase shares of Company Common Stock (the "Company Stock Options") and each restricted stock award ("Restricted Stock Awards"), in each case granted under any plan, arrangement or agreement (the "Company Equity Plans") disclosed in Section 3.03 of Company Disclosure Schedule, whether vested or unvested, in the case of Company Stock Options, and whether or not subject to forfeiture, in the case of Restricted Stock Awards, shall:

(i) in the case of Company Stock Options, be cancelled by the Company in consideration for which the holder thereof shall thereupon be entitled to receive as soon as reasonably practicable after the Effective Time, a cash payment from the Company in respect of such cancellation in an amount (if any) equal to (A) the product of (x) the number of shares of Company Common Stock subject to such Company Stock Option, whether or not then exercisable, and (y) the excess, if any, of the Common Merger Consideration over the exercise price per share of Company Common Stock subject to such Company Stock Option, minus (B) all applicable federal, state and local Taxes required to be withheld by the Company; and

(ii) in the case of Restricted Stock Awards, terminate all forfeiture restrictions and, pursuant to the terms of Section 2.02, cause the Paying Agent to pay to the holders thereof the Common Merger Consideration in respect of each share of Company Common Stock subject to such award held of record by such holder less all applicable federal, state and local Taxes required to be withheld by the Company with respect thereto.

(b) Subject to the terms and upon the conditions set forth herein, as of the Effective Time, the warrant to purchase shares of the Company Common Stock granted to Morgan Stanley Capital Group, Inc. on November 23, 2004 (the "Warrant") shall, in accordance with its terms and without any action on the part of the holder thereof, Company, Parent or Merger Co, no longer represent the right to receive shares of Company Common Stock upon the due exercise thereof, and shall thereafter represent the right to receive cash in accordance with the terms of the Warrant. Prior to the Effective Time, Company shall take any and all actions reasonably requested by Parent to effectuate this Section 2.04(b) as required by the Warrant, including, no later than 15 days prior to the Effective Time, delivering to the Warrant holder the notice required to be given by it pursuant to Section 10.4 of the Warrant.

Section 2.05 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to the contrary and to the extent available under the DGCL, Shares that are outstanding immediately prior to the Effective Time and that are held by any stockholder who is entitled to demand and properly demands (and does

A-6

not timely withdraw such demand) appraisal of such Shares (the "Dissenting Shares") pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL shall not be converted into, or represent the right to receive, the Merger Consideration. Any such stockholder shall instead be entitled to receive payment of the fair value of such stockholder's Dissenting Shares in accordance with the provisions of Section 262 of the DGCL; provided, however, that all Dissenting Shares held by any stockholder who shall have failed to perfect or who otherwise shall have withdrawn, in accordance with Section 262 of the DGCL, or lost such stockholder's rights to appraisal of such Shares under Section 262 of the DGCL shall thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration, without any interest thereon, upon surrender of the Certificate or Certificates that formerly evidenced such Shares in the manner provided in Section 2.02(b) and (c), as applicable.

The Company shall give Parent (i) prompt notice of any demands received by the Company for appraisal of any Shares, withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company and (ii) the opportunity to participate in and direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment or agree to make any payment with respect to any demands for appraisal or offer to settle or settle any such demands.

(ii) Parent does not make, within three business days after the receipt of such notice, a binding, written and complete (including any schedules or exhibits) proposal that the Company Board determines in good faith, after consultation with its financial advisor, is at least as favorable to the stockholders of the Company as such Superior Proposal and which, by its terms, may be accepted at any time prior to the later of the end of such three business day period and one full business day after receipt by the Company Board of such notice; and

(iii) in the event of any termination of this Agreement by the Company pursuant to this paragraph 6.04(d), the Company pays the Termination Fee under Section 8.03(c) concurrently with and as a condition of such termination.

A-29

of the members of the Company Board or any applicable Law, then the Company Board or such independent committee may make a Change in Board Recommendation, but only if:

(i) the Company Board shall have first provided prior written notice to Parent that it is prepared to make a Change in Board Recommendation, which notice shall include a reasonably detailed explanation of the reasons for such Change in Board Recommendation; and

(ii) Parent does not make, within three business days (or such shorter period as the Company Board determines in good faith (as set forth in a resolution of the Company Board or a committee of the Company Board), after consultation with legal counsel, is necessary in order to satisfy any applicable requirement of Law) after the receipt of such notice, a binding, written and complete (including any schedules or exhibits) proposal that causes the Company Board to determine in good faith, after consultation with its financial advisor and legal counsel, to refrain from making such Change in Board Recommendation and which, by its terms, may be accepted at any time prior to the later of the end of such three business day period and one full business day after receipt by the Company Board of such notice.

Section 6.05 Directors' and Officers' Indemnification and Insurance.

(a) For a period of six years after the Effective Time, unless otherwise required by applicable Law, the Surviving Corporation shall and Parent shall cause the Surviving Corporation to, cause the Charter Documents of the Surviving Corporation and its Subsidiaries to contain provisions no less favorable with respect to the indemnification of and advancement of expenses to directors and officers than are set forth in the Charter Documents of the Company (or the relevant Subsidiary) as in effect on the date hereof. SemGroup LP shall, and shall cause the Surviving Corporation to, indemnify and advance expenses to, each present and former director or officer of the Company and each present and former director or officer of each Subsidiary (collectively, the "Indemnified Parties"), in respect of actions, omissions or events through the Effective Time to the fullest extent permitted by Law. Without limiting the generality of the preceding sentence, if any Indemnified Party becomes involved in any actual or threatened action, suit, claim, proceeding or investigation covered by this Section 6.05 after the Effective Time, Parent shall cause the Surviving Corporation to, to the fullest extent permitted by Law, promptly advance to such Indemnified Party his or her legal or other expenses (including the cost of any investigation and preparation incurred in connection therewith).

(c) If Parent or the Surviving Corporation or any of its successors or assigns (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or shall cease to continue to exist for any reason or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of Parent or the Surviving Corporation and the transferee or transferees of such properties and assets, as applicable, shall assume all of the obligations set forth in this Section 6.05.

(d) The Indemnified Parties shall be third party beneficiaries of this Section 6.05. The provisions of this Section 6.05 are intended to be for the benefit of each such Indemnified Party, his or her heirs and his or her representatives.

From and after the Effective Time, the Surviving Corporation and its subsidiaries shall, and Parent shall cause the Surviving Corporation and its subsidiaries to, honor in accordance with their terms (including, without limitation, terms which provide for amendment or termination), all contracts, agreements, arrangements, policies, plans and commitments of the Company and the Subsidiaries as in effect immediately prior to the Effective Time that are applicable to any current or former employees or directors of the Company or any Subsidiary.

(e) Nothing in this Section 6.06, expressed or implied, shall be construed to prevent Parent or any subsidiary of Parent (including, after the Effective Time, the Surviving Corporation) from terminating or modifying to any extent or in any respect any benefit plan that Parent or any subsidiary of Parent (including, after the Effective Time, the Surviving Corporation) may establish or maintain; provided that appropriate provision is made to comply with the provisions of this Section 6.06. Nothing in this Section 6.06 is intended to confer upon any person other than the parties hereto any rights or remedies hereunder.

The Company, Parent and Merger Co each hereby agree promptly (and in any event within three business days) to notify each other party hereto of any event, circumstance or condition of which the Company, Parent or Merger Co becomes aware that could reasonably be expected to constitute or give rise to a material breach of any representation or warranty, covenant or condition contained in this Agreement.

(b) Without limiting the generality of the foregoing:

(i) Each party agrees to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby as promptly as practicable following the date of this Agreement and to supply promptly any

A-33

additional information and documentary material (a "Second Request") that may be requested pursuant to the HSR Act. In the event a Second Request is made, the Expiration Date shall automatically be extended until December 31, 2006.

(ii) Parent, Merger Co and the Company shall:

(A) take promptly any or all of the following actions to the extent necessary to eliminate any concerns on the part of any Governmental Authority with jurisdiction over the enforcement, of any applicable antitrust Law ("Government Antitrust Authority") regarding the legality under any antitrust Law of the Merger: entering into negotiations, providing information, making proposals, entering into and performing agreements or submitting to judicial or administrative orders, or selling or otherwise disposing of, or holding separate (through the establishment of a trust or otherwise), particular assets or categories of assets, or businesses, of (1) the Parent and Merger Co or any of their subsidiaries (which for purposes of this Section 6.09 shall only be deemed to include an entity in which SemGroup LP owns, directly or indirectly, 50% or more of the voting securities or equity of such entity) or (2) the Company and its Subsidiaries;

(B) use their reasonable best efforts to prevent the entry in a judicial or administrative proceeding brought under any antitrust Law by any Government Antitrust Authority of any permanent or preliminary injunction or other order that would make consummation of the Merger in accordance with the terms of this Agreement unlawful or that would prevent or delay such consummation;

(C) take promptly, in the event that such an injunction or order has been issued in such a proceeding, any and all steps, including, without limitation, the appeal thereof, the posting of a bond or the other steps contemplated by clause (A) above, necessary to vacate, modify or suspend such injunction or order so as to permit such consummation on a schedule as close as possible to that contemplated by this Agreement; and

(D) take promptly all other actions and do all other things necessary and proper to avoid or eliminate each and every impediment under any antitrust Law that may be asserted by any Government Antitrust Authority or any other party to the consummation of the Merger by the Parent and Merger Co in accordance with the terms of this Agreement.

(iii) Notwithstanding anything to the contrary set forth in this Section 6.09(b), none of Parent, Merger Co nor the Company (nor any Affiliate of the foregoing) shall be required to take any of the actions described in subsections (A) through (D) of Section 6.09(b)(ii), if to do so would, in the reasonable, good faith judgment of the management committee of the general partner of SemGroup LP, have a material adverse effect upon the business plans of SemGroup LP for the conduct of the business after the Closing of (x) the Surviving Corporation and its Subsidiaries; (y) TransMontaigne Partners and the MLP Subsidiaries; and (z) SemGroup LP and its Subsidiaries, all taken as a whole. If after complying with all of the terms of this Section 6.09, Parent and Merger Co and their Subsidiaries or Affiliates would be required to agree to or take any action having the effect referred to in the first sentence of this Section 6.09(b)(iii), Parent shall have the option of terminating this Agreement upon (A) a final determination by the Government Antitrust Authority that taking or agreeing to take such action is required in order to consummate the Merger and (B) payment to the Company of the Reverse Termination Fee. For clarity, in order for a material adverse effect to be deemed to occur the actions referred to in the first sentence of this Section 6.09(b)(iii) would have to result in a minimum financial impact in excess of $50 million.

A-34

(c) Notwithstanding anything to the contrary set forth in this Section 6.09, neither Parent nor Merger Co, nor any of their respective Affiliates, shall be required to take any action that, in the opinion of Parent after consultation with outside counsel, is reasonably likely to cause SemGroup LP or any of its subsidiaries or Affiliates, other than the Company (and its Subsidiaries) and TransMontaigne Partners (and its subsidiaries) after the Effective Time, to be subject to the reporting requirements of Section 13(a) or 15(d) of the Exchange Act or otherwise be required to file periodic reports under the Exchange Act.

(d) Prior to the Closing, at the written request of Parent, the Company shall commence a tender offer and consent solicitation with respect to any or all of the Notes in accordance with the written terms and conditions provided by Parent to the Company and applicable Law (collectively, the "Debt Tender"). Unless otherwise agreed by the Company in writing, the Debt Tender shall not be required to close on or prior to the Closing. In the event this Agreement is terminated by either party pursuant to Article VIII, then Parent shall promptly reimburse the Company for any reasonable out-of-pocket costs, fees and expenses incurred by the Company (including reasonable fees and expenses incurred by counsel and financial advisers to the Company and any other third parties engaged by the Company with the consent of Parent) in connection with the Debt Tenders and shall indemnify the Company and its officers, directors, employees, agents and other representatives (collectively, the "indemnitees") for any other liabilities incurred by the Company and the indemnitees in connection with the Debt Tender except for liabilities resulting from actions taken, or failed to be taken, by the Company or the indemnitees that are contrary to the written instructions of the Parent.

Section 6.10 Public Announcements. The initial press release relating to this Agreement shall be a press release issued jointly by the parties, or separate press releases issued by each party, in either case the text of which has been agreed to by each of Parent and the Company. Thereafter, each of Parent and the Company shall consult with each other before issuing any press release or otherwise making any public statements with respect to this Agreement or the Merger, except to the extent public disclosure is required by applicable Law or the requirements of the NYSE in which case the issuing party shall use its reasonable best efforts to consult with the other party before issuing any such release or making any such public statement.

The Company shall use its reasonable best efforts to obtain and deliver to Parent at the Closing evidence reasonably satisfactory to Parent of the resignation effective as of the Effective Time, of those directors of the Company or any Subsidiary designated by Parent to the Company in writing at least ten business days prior to the Closing.

The Board of Directors
TransMontaigne, Inc.
1670 Broadway, Suite 3100
Denver, CO 80202

Dear Members of the Board:

We understand that TransMontaigne, Inc., a Delaware corporation (the "Company"), is considering a transaction whereby the Company will merge with TMG Acquisition Company ("MergerCo"), a Delaware corporation and a wholly owned direct subsidiary of SemGroup Subsidiary Holding, L.L.C., a Delaware limited liability company ("SemGroup Holdings"), and an indirect subsidiary of SemGroup, L.P., an Oklahoma limited partnership ("SemGroup") (the "Transaction"). Pursuant to the terms of a draft of an Amended and Restated Agreement and Plan of Merger, dated May 22, 2006 (the "Agreement"), the Company will become a wholly owned subsidiary of SemGroup Holdings and each of the issued and outstanding shares of the common stock of the Company, par value of $0.01 per share (the "Company Common Stock"), will be converted into the right to receive $11.25 in cash, without interest (the "Consideration"). 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 the Company Common Stock of the Consideration to be received by such holders in the Transaction.

UBS Securities LLC ("UBS") has acted as financial advisor to the Board of Directors of the Company in connection with the Transaction and will receive a fee for its services, a portion of which is payable in connection with this opinion and a significant portion of which is contingent upon consummation of the Transaction. In the past, UBS and its affiliates have provided investment banking services to the Company unrelated to the proposed Transaction, for which UBS and its affiliates have received compensation. In the ordinary course of business, UBS, its successors and affiliates may hold or trade, for their own accounts and the accounts of their customers, securities of the Company and SemGroup and their respective affiliates and, accordingly, may at any time hold a long or short position in such securities.

Our opinion does not address the relative merits of the Transaction as compared to other business strategies or transactions that might be available with respect to the Company or the Company's underlying business decision to effect the Transaction. Our opinion does not constitute a recommendation to any shareholder of the Company as to how such shareholder should vote or act with respect to the Transaction. At your direction, we have not been asked to, nor do we, offer any opinion as to the terms (other than the Consideration) of the Agreement or the form of the Transaction. In rendering this opinion, we have assumed, with your consent, that (i) the final executed form of the Agreement does not differ in any material respect from the draft that we have examined; (ii) SemGroup, SemGroup Holdings, MergerCo and the Company will comply with all the material terms of the Agreement; and (iii) the Transaction will be consummated in accordance with the terms of the Agreement without any adverse waiver or amendment of any material term or condition thereof.

UBS Investment Bank is a business group of UBS AG.
UBS Securities LLC is a subsidiary of UBS AG.

B-1

We have also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any material adverse effect on SemGroup, SemGroup Holdings, MergerCo, the Company or the Transaction. In 2004, we assisted the Company in contacting parties regarding a potential business combination with the Company, however, in connection with the Transaction, we have not been authorized to solicit, and have not solicited, indications of interest in a business combination with the Company from any party.

In arriving at our opinion, we have, among other things: (i) reviewed certain publicly available business and historical financial information relating to the Company; (ii) reviewed certain internal financial information and other data relating to the business and financial prospects of the Company that were provided to us by the Company and not publicly available, including financial forecasts and estimates prepared by the management of the Company; (iii) conducted discussions with members of the senior management of the Company concerning the business and financial prospects of the Company; (iv) reviewed publicly available financial and stock market data with respect to certain other companies we believe to be generally relevant; (v) compared the financial terms of the Transaction with the publicly available financial terms of certain other transactions we believe to be generally relevant; (vi) reviewed current and historical market prices of the Company Common Stock; (vii) reviewed the Agreement; and (viii) conducted such other financial studies, analyses and investigations, and considered such other information, as we deemed necessary or appropriate.

In connection with our review, with your consent, we have not assumed any responsibility for independent verification of any of the information reviewed by us for the purpose of this opinion and have, with your consent, relied on such information being complete and accurate in all material respects. In addition, with your consent, we have not made any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of the Company or SemGroup, nor have we been furnished with any such evaluation or appraisal. With respect to the financial forecasts and estimates referred to above, we have assumed, at your direction, that they have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company as to the future performance of the Company. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Consideration to be received by holders of the Company Common Stock in the Transaction is fair, from a financial point of view, to such holders.

This opinion is provided for the benefit of the Board of Directors in connection with, and for the purpose of, its consideration of the Transaction.

		Very truly yours,
		UBS SECURITIES LLC

APPENDIX C

GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

§ 262. APPRAISAL RIGHTS.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to §251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of § 251 of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

C-1

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then, either a constituent corporation before the effective date of the merger or consolidation, or the surviving or resulting corporation within 10 days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give

C-2

either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the

C-3

Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
