MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT
      The board of directors of Thermo Electron Corporation, or Thermo, and the board of directors of Fisher Scientific International Inc., or Fisher, have agreed to a strategic combination of the two companies under the terms of the Agreement and Plan of Merger, dated as of May 7, 2006, which is referred to as the merger agreement. Upon completion of the merger of a direct, wholly-owned subsidiary of Thermo with and into Fisher, Thermo will acquire Fisher, and Fisher will become a direct, wholly-owned subsidiary of Thermo.
      If the merger is completed, Fisher stockholders will have the right to receive 2.0 shares of Thermo common stock for each share of Fisher common stock. This exchange ratio is fixed and will not be adjusted to reflect stock price changes prior to closing of the merger. Based on the closing price of Thermo common stock on the New York Stock Exchange on May 5, 2006, the last trading day before public announcement of the merger, the 2.0 exchange ratio represented approximately $78.90 in value for each share of Fisher common stock. Based on the closing price of Thermo common stock on the New York Stock Exchange on                     , 2006, the latest practicable date before the date of this document, the 2.0 exchange ratio represented approximately $          .           in value for each share of Fisher common stock. Thermo stockholders will continue to own their existing Thermo shares.
      The merger has been structured to qualify as a reorganization for U.S. federal income tax purposes. Accordingly, Fisher stockholders are not expected to recognize any gain or loss for U.S. federal income tax purposes on the exchange of shares of Fisher common stock for Thermo common stock in the merger. Upon completion of the merger, we estimate that current Thermo stockholders will own approximately 39% of the combined company and former Fisher stockholders will own approximately 61% of the combined company.
      At the special meeting of Thermo stockholders, which we refer to as the Thermo special meeting, Thermo stockholders will be asked to vote on the issuance of Thermo common stock to Fisher stockholders and an amendment to the Amended and Restated Certificate of Incorporation of Thermo Electron Corporation, which we refer to as the Thermo charter, each of which is necessary to effect the merger. The stock issuance proposal requires the affirmative vote of holders of a majority of the Thermo common stock present or represented and entitled to vote on the proposal. The Thermo charter amendment proposal requires the affirmative vote of holders of a majority of the outstanding shares of Thermo common stock entitled to vote on the proposal.
      At the special meeting of Fisher stockholders, which is referred to as the Fisher special meeting, Fisher stockholders will be asked to vote on the approval and adoption of the merger agreement. In order to complete the merger, an affirmative vote of holders of a majority of the outstanding shares of Fisher common stock entitled to vote on the proposal must vote to approve and adopt the merger agreement.
      The Thermo board of directors unanimously recommends that the Thermo stockholders vote “FOR” the proposal to issue shares of Thermo common stock in the merger and “FOR” the proposal to amend the Thermo charter.
      The Fisher board of directors unanimously recommends that the Fisher stockholders vote “FOR” the proposal to approve and adopt the merger agreement.
      The obligations of Thermo and Fisher to complete the merger are subject to the satisfaction or waiver of several conditions set forth in the merger agreement. More information about Thermo, Fisher and the merger is contained in this joint proxy statement/prospectus. Thermo and Fisher encourage you to read this entire joint proxy statement/prospectus carefully, including the section entitled “Risk Factors” beginning on page 13.
      We look forward to the successful combination of Thermo and Fisher.

QUESTIONS AND ANSWERS
      The following are some questions that you, as a stockholder of Thermo or Fisher, may have regarding the merger and the other matters being considered at the stockholders’ meetings and the answers to those questions. Thermo and Fisher urge you to read carefully the remainder of this document because the information in this section does not provide all the information that might be important to you with respect to the merger and the other matters being considered at the stockholders’ meetings. Additional important information is also contained in the annexes to and the documents incorporated by reference into this document.
Q: Why am I receiving this document?
A: Thermo and Fisher have agreed to the combination of Fisher with Thermo under the terms of a merger agreement that is described in this document. A copy of the merger agreement is attached to this document as Annex A.
  In order to complete the merger, Thermo stockholders must vote to approve the issuance of shares of Thermo common stock in connection with the merger and to approve an amendment to Thermo’s charter to, among other things, increase the number of shares of Thermo common stock authorized for issuance, and Fisher stockholders must vote to approve and adopt the merger agreement.
 
  Thermo and Fisher will hold separate stockholders’ meetings to obtain these approvals. This document contains important information about the merger and the meetings of the respective stockholders of Thermo and Fisher, and you should read it carefully. The enclosed voting materials allow you to vote your shares without attending your respective stockholders’ meeting.
 
  Your vote is important. We encourage you to vote as soon as possible.
Q: When and where will the stockholders’ meetings be held?
A:  The Thermo special meeting will be held at, Thermo’s principal executive offices at 81 Wyman Street, Waltham, Massachusetts 02451 on August 30, 2006 at 10:00 a.m., local time. The Fisher special meeting will be held at the Sheraton Dover Hotel, 1570 North DuPont Highway, Dover, Delaware, on August 30, 2006 at 10:00 a.m., local time.
Q: How do I vote?
A: If you are a stockholder of record of Thermo as of the record date for the Thermo special meeting or a stockholder of record of Fisher as of the record date for the Fisher special meeting, you may vote in person by attending your stockholders’ meeting or, to ensure your shares are represented at the meeting, you may vote by:
  •  accessing the Internet website specified on your proxy card;
 
  •  calling the toll-free number specified on your proxy card; or
 
  •  signing and returning the enclosed proxy card in the postage-paid envelope provided.
  If you hold Thermo shares or Fisher shares in the name of a bank or broker, please follow the voting instructions provided by your bank or broker to ensure that your shares are represented at your stockholders’ meeting.
Q: What will happen if I fail to vote or I abstain from voting?
A: If you are a Thermo stockholder and fail to vote or vote to abstain:
  •  it will have the same effect as a vote against the Thermo charter amendment proposal, which is necessary to complete the merger; and
 
  •  it will have no effect on the proposal to approve the issuance of shares of Thermo common stock in the merger, assuming a quorum is present.

iv


Table of Contents

  If you are a Fisher stockholder and fail to vote or vote to abstain:
  •  it will have the same effect as a vote against the proposal to approve and adopt the merger agreement.
Q: If my shares are held in street name by my broker, will my broker vote my shares for me?
A: If you hold your shares in a stock brokerage account or if your shares are held by a bank or nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank or broker. Please note that you may not vote shares held in street name by returning a proxy card directly to Thermo or Fisher or by voting in person at your stockholders’ meeting unless you provide a “legal proxy,” which you must obtain from your bank or broker. Further, brokers who hold shares of Thermo or Fisher common stock on behalf of their customers may not give a proxy to Thermo or Fisher to vote those shares without specific instructions from their customers.
  If you are a Thermo stockholder and you do not instruct your broker on how to vote your shares:
  •  your broker may not vote your shares on the Thermo charter amendment proposal, which will have the same effect as a vote against the Thermo charter amendment proposal; and
 
  •  your broker may not vote your shares on the proposal to approve the issuance of shares of Thermo common stock in the merger, which will have no effect on the vote on this proposal, assuming a quorum is present.
  If you are a Fisher stockholder and you do not instruct your broker on how to vote your shares:
  •  your broker may not vote your shares, which will have the same effect as a vote against the proposal to approve and adopt the merger agreement.
Q: What will happen if you return your proxy card without indicating how to vote?
A: If you return your proxy card without indicating how to vote on any particular proposal, the Thermo or Fisher common stock represented by your proxy will be voted in favor of that proposal.
Q: Can I change my vote after I have returned a proxy or voting instruction card?
A: Yes. You can change your vote at any time before your proxy is voted at your stockholders’ meeting. You can do this in one of three ways:
  •  you can send a signed notice of revocation;
 
  •  you can grant a new, valid proxy bearing a later date; or
 
  •  if you are a holder of record, you can attend your stockholders’ meeting and vote in person, which will automatically cancel any proxy previously given, or you may revoke your proxy in person, but your attendance alone will not revoke any proxy that you have previously given.
  If you choose either of the first two methods, you must submit your notice of revocation or your new proxy to the Secretary of Thermo or Fisher, as appropriate, no later than the beginning of the applicable stockholders’ meeting. If your shares are held in street name by your bank or broker, you should contact your broker to change your vote.
Q: What do I need to do now?
A: Carefully read and consider the information contained in and incorporated by reference into this document, including its annexes.
  In order for your shares to be represented at your stockholders’ meeting:
  •  you can attend your stockholders’ meeting in person;

  •  you can indicate on the enclosed proxy card how you would like to vote and return the proxy card in the accompanying pre-addressed postage paid envelope.
Q: Should I send in my Fisher stock certificates now?
A: No. Fisher stockholders should not send in any stock certificates now. After the merger is completed, Thermo’s exchange agent will send former Fisher stockholders a letter of transmittal explaining what they must do to exchange their Fisher stock certificates for the merger consideration payable to them.
 
If you are a Thermo stockholder, you are not required to take any action with respect to your Thermo stock certificates.

SUMMARY
      This summary highlights information contained elsewhere in this document and may not contain all the information that is important to you. Thermo and Fisher urge you to read carefully the remainder of this document, including the attached annexes, and the other documents to which we have referred you because this section does not provide all the information that might be important to you with respect to the merger and the other matters being considered at the applicable stockholders’ meeting. See also the section entitled “Where You Can Find More Information” beginning on page 89. We have included page references to direct you to a more complete description of the topics presented in this summary.  
The Merger and the Merger Agreement
The Merger (See page 17)
      A copy of the merger agreement is attached as Annex A to this document. Thermo and Fisher encourage you to read the entire merger agreement carefully because it is the principal document governing the merger.  
Form of Merger (See page 17)
      Subject to the terms and conditions of the merger agreement, at the effective time of the merger, Trumpet Merger Corporation, a direct, wholly-owned subsidiary of Thermo formed for the purposes of the merger, will be merged with and into Fisher. Fisher will survive the merger as a direct, wholly-owned subsidiary of Thermo. After the merger, Thermo will be called “Thermo Fisher Scientific Inc.,” referred to in this document as the combined company.  
Consideration to be Received in the Merger; Treatment of Stock Options (See page 17)
      Fisher stockholders will receive 2.0 shares of Thermo common stock for each share of Fisher common stock they hold. The exchange ratio is fixed and will not be adjusted for changes in the market value of the common stock of Fisher or Thermo. Because of this, the implied value of the consideration to Fisher stockholders will fluctuate between now and the completion of the merger. Based on the closing price of Thermo common stock on the New York Stock Exchange, or NYSE, on May 5, 2006, the last trading day before public announcement of the merger, the 2.0 exchange ratio represented approximately $78.90 in value for each share of Fisher common stock. Based on the closing price of Thermo common stock on the NYSE on                     , 2006, the latest practicable date before the date of this document, the 2.0 exchange ratio represented approximately $     .     in value for each share of Fisher common stock.  
Material U.S. Federal Income Tax Consequences of the Merger (See page 47)
      The merger has been structured to qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, which we refer to as the Code. Assuming the merger qualifies as such a reorganization, for U.S. federal income tax purposes, holders of Fisher common stock whose shares of Fisher common stock are exchanged in the merger for shares of Thermo common stock will not recognize gain or loss. It is a condition to the completion of the merger that Thermo and Fisher receive written opinions from their respective counsel to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Neither Thermo nor Fisher intends to waive this closing condition. In the event that either Thermo or Fisher waives receipt of such opinion from its counsel, however, Thermo and Fisher will resolicit the approval of its stockholders after providing appropriate disclosure.  
 
      Tax matters are very complicated and the tax consequences of the merger to each Fisher stockholder will depend on such stockholder’s particular facts and circumstances. Fisher stockholders are urged to consult their tax advisors to understand fully the tax consequences to them of the merger.

Table of Contents

Thermo and Fisher stockholders generally. The executive officers of Thermo and Fisher have existing agreements with Thermo or Fisher, as applicable, that provide for severance benefits in connection with termination of employment following a change in control of Thermo or Fisher. Some of Thermo’s and Fisher’s compensation and benefits plans provide for payment or accelerated vesting or distribution of the rights or benefits thereunder upon a change in control of Thermo or Fisher, as applicable.
      The Thermo and Fisher boards of directors were aware of these interests and considered them, among other matters, in approving the merger agreement and the transactions contemplated by the merger agreement.
Directors and Management Following the Merger (See page 46)
      Following the merger, the board of directors of the combined company will consist of eight directors. The board will be comprised of Marijn E. Dekkers, Jim P. Manzi, Peter Manning, Michael E. Porter, Elaine S. Ullian and Paul M. Meister and two additional independent directors to be designated by Fisher.
      Following the merger, Mr. Dekkers will serve as President and Chief Executive Officer and Mr. Meister will serve as non-executive Chairman of the board of directors, of the combined company.
Regulatory Approvals Required for the Merger (See page 49)
      Thermo and Fisher have each agreed to use our reasonable best efforts in order to obtain all regulatory approvals required in order to consummate the merger. These approvals include antitrust filings with the U.S. Department of Justice and the U.S. Federal Trade Commission and expiration or termination of the required waiting periods, as well as the approval of the European Commission. We also expect to file notices with antitrust and competition authorities in other jurisdictions. Although we do not expect regulatory authorities to raise any significant objections in connection with their review of the merger, we cannot assure you that we will obtain all required regulatory approvals or that these regulatory approvals will not contain terms, conditions or restrictions that would be detrimental to the combined company after the completion of the merger.
Expected Timing of the Merger (See page 52)
      We currently expect to complete the merger in the fourth quarter of 2006, subject to receipt of required stockholder and regulatory approvals.
Conditions to Completion of the Merger (See page 52)
      The obligations of Fisher and Thermo to complete the merger are subject to the satisfaction of the following conditions:
  •  the adoption of the merger agreement by Fisher stockholders;
 
  •  the approval of the issuance of Thermo common stock in the merger and the Thermo charter amendment proposal by Thermo stockholders;
 
  •  the termination or expiration of the applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which we refer to as the HSR Act, all required notifications and filings under Council Regulation (EC) 139/2004 of the European Community, which we refer to as the ECMR;
 
  •  the receipt of other requisite regulatory approvals, unless failure to obtain them would not, individually or in the aggregate, have a material adverse effect on Fisher and its subsidiaries, taken as a whole, or Thermo and its subsidiaries, taken as a whole (after giving effect to the merger);
 
  •  no judgment or other legal prohibition of any court or other governmental entity shall be in effect that prohibits the completion of the merger;

  •  the Securities and Exchange Commission, which we refer to as the SEC, having declared effective the registration statement of which this document forms a part; and
 
  •  the authorization for listing by the NYSE of the Thermo common stock issuable to Fisher stockholders in the merger.
      In addition, each of Fisher’s and Thermo’s obligation to complete the merger is subject to the satisfaction or waiver of the following additional conditions:
  •  the representations and warranties of the other party being true and correct, subject to the material adverse effect standard provided in the merger agreement;
 
  •  the other party having performed or complied with, in all material respects, all obligations required to be performed or complied with by it under the merger agreement;
 
  •  the other party and its respective subsidiaries, taken as a whole, not having suffered any material adverse effect, as defined in the merger agreement;
 
  •  the receipt of an officer’s certificate executed by each of the other party’s Chief Executive Officer and Chief Financial Officer stating that the three preceding conditions have been satisfied; and
 
  •  the receipt of an opinion of that party’s counsel to the effect that the merger will qualify as a “reorganization” under the Code.
Termination of the Merger Agreement (See page 53)
      Thermo and Fisher can jointly agree to terminate the merger agreement at any given time. Either company may also terminate the merger agreement if the merger is not completed by May 7, 2007 or under other circumstances described in this document. See the section entitled “The Merger Agreement — Termination of the Merger Agreement” beginning on page 53 for a discussion of each of Thermo’s and Fisher’s rights to terminate the merger agreement.
Expenses and Termination Fees (See page 54)
      Generally, all fees and expenses incurred in connection with the merger agreement and the transactions contemplated by the merger agreement will be paid by the party incurring those expenses, subject to the specific exceptions discussed in this document. See the section entitled “The Merger Agreement — Termination Fee” beginning on page 54 for a complete discussion of the circumstances under which termination fees will be required to be paid.
Accounting Treatment (See page 48)
      Thermo prepares its financial statements in accordance with accounting principles generally accepted in the United States of America, which is referred to as GAAP. The merger will be accounted for using the purchase method of accounting. As discussed under “Accounting Treatment” on page 48, based upon the terms of the exchange and other factors, such as the composition of the combined company’s board and senior management, Thermo is considered to be the acquirer of Fisher for accounting purposes. This means that Thermo will allocate the purchase price to the fair value of Fisher’s assets and liabilities at the acquisition date, with the excess purchase price being recorded as goodwill. Under the purchase method of accounting, goodwill is not amortized but is tested for impairment at least annually.
Appraisal Rights (See page 51)
      Under Delaware law, the holders of Fisher common stock are not entitled to appraisal rights in connection with the merger.

The Special Meetings
The Thermo Special Meeting (See page 70)
      The Thermo special meeting will be held at Thermo’s principal executive offices at 81 Wyman Street, Waltham, Massachusetts 02451, at 10:00 a.m., local time, on August 30, 2006. At the Thermo special meeting, Thermo stockholders will be asked to:
  •  approve the issuance of Thermo common stock in the merger;
 
  •  approve the Thermo charter amendment proposal, which will, effective upon the completion of the merger, increase the authorized number of shares of Thermo common stock from 350,000,000 to 1.2 billion and change the name of Thermo to Thermo Fisher Scientific Inc.;
 
  •  vote upon an adjournment of the Thermo special meeting, if necessary, to solicit additional proxies if there are not sufficient votes for each of the foregoing proposals; and
 
  •  transact any other business that may properly be brought before the Thermo special meeting or any adjournments or postponements thereof.

On that date there were                      shares of Thermo common stock outstanding, less than      % of which were owned and entitled to be voted by Thermo directors and executive officers and their affiliates. We currently expect that Thermo’s directors and executive officers will vote their shares in favor of the merger, although none of them has entered into any agreements obligating them to do so.
      You can cast one vote for each share of Thermo common stock you own. The proposals require different percentages of votes in order to approve them:
  •  The issuance of Thermo common stock to Fisher stockholders requires approval by an affirmative vote of holders of a majority of the Thermo common stock present or represented and entitled to vote on the proposal.
 
  •  The Thermo charter amendment proposal requires the affirmative vote of holders of a majority of the outstanding shares of Thermo common stock entitled to vote on the proposal.
 
  •  Approval of the proposal to adjourn the Thermo special meeting, if necessary, for the purpose of soliciting additional proxies requires that the votes cast favoring the proposal exceed the votes cast opposing the proposal.

RISK FACTORS
      In addition to the other information included and incorporated by reference into this document, including the matters addressed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements,” you should carefully consider the following risks before deciding whether to vote for adoption and approval of the merger agreement, in the case of Fisher stockholders, or for the issuance of shares of Thermo common stock in the merger and the Thermo charter amendments, in the case of Thermo stockholders. In addition, you should read and consider the risks associated with each of the businesses of Thermo and Fisher because these risks will also affect the combined company. These risks can be found in Thermo’s Quarterly Report on Form 10-Q for the first quarter of 2006 and in the Fisher Current Report on Form 8-K filed on May 11, 2006, each of which are filed with the SEC and incorporated by reference into this document. You should also read and consider the other information in this document and the other documents incorporated by reference into this document. See the section entitled “Where You Can Find More Information” beginning on page 89.
The exchange ratio is fixed and will not be adjusted in the event of any change in either Thermo’s or Fisher’s stock price.
      Upon closing of the merger, each share of Fisher common stock will be converted into the right to receive 2.0 shares of Thermo common stock. This exchange ratio will not be adjusted for changes in the market price of either Thermo common stock or Fisher common stock. Changes in the price of Thermo common stock prior to the merger will affect the value that Fisher common stockholders will receive on the date of the merger. Stock price changes may result from a variety of factors (many of which are beyond our control), including the following factors:
  •  changes in our businesses, operations and prospects;
 
  •  changes in market assessments of the business, operations and prospects of either company;
 
  •  market assessments of the likelihood that the merger will be completed, including related considerations regarding regulatory approval of the merger;
 
  •  interest rates, general market and economic conditions and other factors generally affecting the price of Thermo’s and Fisher’s common stock; and
 
  •  federal, state and local legislation, governmental regulation and legal developments in the businesses in which Fisher and Thermo operate.
      The prices of Thermo common stock and Fisher common stock at the closing of the merger may vary from their respective prices on the date the merger agreement was executed, on the date of this document and on the date of the respective stockholder meetings. As a result, the value represented by the exchange ratio will also vary. For example, based on the range of closing prices of Thermo common stock during the period from May 5, 2006, the last trading day before public announcement of the merger, through                     , 2006, the latest practicable date before the date of this document, the exchange ratio represented a value ranging from a high of $     .     to a low of $     .     for each share of Fisher common stock.
      Because the date that the merger is completed may be later than the date of the stockholder meetings, at the time of your stockholder meeting, you will not know the exact market value of the Thermo common stock that Fisher stockholders will receive upon completion of the merger. You should consider the following two risks:
  •  If the price of Thermo common stock increases between the date the merger agreement was signed or the date of the Thermo special meeting and the effective time of the merger, Fisher stockholders will receive shares of Thermo common stock that have a market value that is greater than the market value of such shares when the merger agreement was signed, and Thermo will pay more for shares of Fisher common stock than the value calculated pursuant to the exchange ratio on the date the merger agreement was signed or on the date of the Thermo annual meeting. Therefore, Thermo stockholders

13


Table of Contents

  cannot be sure of the value of the consideration that will be paid to Fisher stockholders upon completion of the merger.
 
  •  If the price of Thermo common stock declines between the date the merger agreement was signed or the date of the Fisher special meeting and the effective time of the merger, including for any of the reasons described above, Fisher stockholders will receive less value for their shares upon completion of the merger than they would have received based on the value calculated pursuant to the exchange ratio on the date the merger agreement was signed or on the date of the Fisher special meeting. Therefore, Fisher stockholders cannot be sure of the market value of the Thermo common stock they will receive upon completion of the merger or the market value of Thermo common stock at any time after the completion of the merger.
The combined company may be unable to integrate successfully the businesses of Thermo and Fisher and realize the anticipated benefits of the merger.
      The merger involves the combination of two companies which currently operate as independent public companies. The combined company will be required to devote significant management attention and resources to integrating its business practices and operations. Potential difficulties the combined company may encounter in the integration process include the following:
  •  if we are unable to successfully combine the businesses of Thermo and Fisher in a manner that permits the combined company to achieve the cost savings and operating synergies anticipated to result from the merger, such anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected;
 
  •  lost sales and customers as a result of certain customers of either of the two companies deciding not to do business with the combined company;
 
  •  complexities associated with managing the combined businesses;
 
  •  integrating personnel from diverse corporate cultures while maintaining focus on providing consistent, high quality products and customer service;
 
  •  potential unknown liabilities and unforeseen increased expenses or delays associated with the merger; and
 
  •  performance shortfalls at one or both of the two companies as a result of the diversion of management’s attention to the merger.
      In addition, Thermo and Fisher have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, diversion of each company’s management’s attention, the disruption or interruption of, or the loss of momentum in, each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies, any of which could adversely affect our ability to maintain relationships with customers and employees or our ability to achieve the anticipated benefits of the merger, or could reduce our earnings or otherwise adversely affect the business and financial results of the combined company.

Failure to complete the merger could negatively impact the stock prices and the future business and financial results of Fisher and Thermo.
      If the merger is not completed, the ongoing businesses of Fisher or Thermo may be adversely affected and Fisher and Thermo will be subject to several risks, including the following:
  •  being required, under certain circumstances under the merger agreement, to pay a termination fee of $300 million, in the case of a payment by Fisher to Thermo, or $200 million, in the case of a payment by Thermo to Fisher;
 
  •  having to pay certain costs relating to the merger, such as legal, accounting, financial advisor and printing fees; and
 
  •  the focus of management of each of the companies on the merger instead of on pursuing other opportunities that could be beneficial to the companies,
in each case, without realizing any of the benefits of having the merger completed. If the merger is not completed, Fisher and Thermo cannot ensure their stockholders that these risks will not materialize and will not materially affect the business, financial results and stock prices of Fisher or Thermo.

THE MERGER
      The following is a discussion of the proposed merger and the merger agreement. This is a summary only and may not contain all of the information that is important to you. A copy of the merger agreement is attached to this document as Annex A and is incorporated by reference herein. Thermo and Fisher stockholders are urged to read this entire document, including the merger agreement, for a more complete understanding of the merger.
Effect of the Merger; Consideration to be Received in the Merger; Treatment of Stock Options and Other Equity-Based Awards
      Under the merger agreement, Trumpet Merger Corporation, a direct, wholly-owned subsidiary of Thermo, will merge with and into Fisher, with Fisher continuing as the surviving corporation. As a result of the merger, Fisher will become a direct, wholly-owned subsidiary of Thermo.
      At the effective time of the merger, each share of Fisher common stock issued and outstanding immediately prior to the effective time of the merger, excluding shares of Fisher common stock owned by Fisher, Thermo or Trumpet Merger Corporation, will be converted into the right to receive 2.0 shares of Thermo common stock.
      The Thermo charter amendment will, among other things, increase the number of shares of Thermo’s authorized common stock from 350,000,000 to 1.2 billion shares, and its approval is a condition to the completion of the merger. Without this increase, Thermo would be unable to complete the merger as it would not have sufficient unissued and unreserved shares to issue and reserve for issuance the shares of common stock required to be issued and reserved for issuance under the merger agreement, and which may be issuable following completion of the merger in connection with Fisher’s convertible debentures and under Thermo’s and Fisher’s equity plans. In determining that an increase in authorized common stock of the combined company to 1.2 billion authorized shares was appropriate, Thermo considered, in addition to the stock issuances described in the preceding sentence, the desire for flexibility to effect any stock splits in the future based on market conditions.
Background of the Merger
      Each of Thermo’s and Fisher’s board of directors has from time to time in recent years engaged with senior management in strategic reviews, and considered ways to enhance its company’s performance and prospects in light of the business and economic environment. For each company these reviews have included consideration of potential transactions with third parties that would further its strategic objectives, and the potential benefits and risks of those transactions. With respect to both Thermo and Fisher, these strategic reviews have on several occasions related to informal exploratory discussions regarding potential strategic transactions, including possible business combinations, with other companies in the life sciences/healthcare industry.
      Thermo and Fisher have for many years had a significant commercial relationship involving Fisher’s distribution of a substantial variety of Thermo products. As a result of this relationship, the companies and their senior managements have become well known to one another. Discussions between Thermo and Fisher’s senior managements in recent years have from time to time included informal discussions of the potential strategic advantages of a possible combination of the two companies, as well as other potential transactions and joint ventures. For example, during 2004 and 2005 Thermo and Fisher had periodic, preliminary discussions regarding potential transactions involving the purchase and sale of certain business units owned by the other, and in 2005 conducted preliminary due diligence with respect to one such proposed transaction. Also in 2005 the companies had preliminary discussions about forming a joint venture to partner in the pursuit of a significant acquisition transaction. Each of these discussions, however, remained exploratory and none led to any transaction.
      Beginning in mid-2005, representatives of senior management of Thermo and Fisher occasionally discussed in general terms their respective companies, the complementary aspects of their businesses and the

17


Table of Contents

potential benefits that a strategic business combination of Thermo and Fisher could provide, including cost and revenue related synergies and the related potential benefits to stockholders, customers and other important constituents of both companies. However, these discussions remained preliminary and ultimately were not pursued.
      Beginning in October 2005, representatives of Fisher senior management and representatives of senior management of another company in the healthcare industry, referred to as Company A, had intermittent informal discussions regarding a possible strategic business combination. In late January 2006, representatives of senior management of Company A and Fisher met to exchange views with respect to a possible strategic business combination. However, no commitment to explore a transaction resulted from the meeting.
      In early February 2006, representatives of senior management of Thermo and Fisher again discussed generally a possible combination of Thermo and Fisher.
      On March 1, 2006, at a meeting of the Fisher board of directors, senior management of Fisher updated the board as to its informal discussions with Company A. At such meeting a variety of differing views were expressed as to the potential merits and challenges posed by a business combination with Company A. The meeting of the Fisher board also included its review and discussion of other strategic alternatives potentially available to Fisher, including a discussion relating to the possibility of a transaction with Thermo.
      Also, in early March 2006, representatives of senior management of Fisher and of another company in the healthcare industry, referred to as Company B, discussed potential areas of business collaboration. These discussions did not relate to a potential business combination transaction.
      In mid-March 2006, representatives of senior management of Company A and Fisher had further discussions as to the potential strategic merits and terms of a business combination. Thereafter, until mid-April 2006, Fisher and Company A and their respective legal and financial advisors engaged in mutual due diligence and continued discussions regarding a possible business combination transaction.
      In early April 2006, representatives of senior management of Thermo and Fisher resumed their previous informal discussions as to a possible combination of Thermo and Fisher. Representatives of Fisher advised Thermo that Fisher was engaged in discussions with another party relating to a potential strategic combination. They agreed that both Thermo and Fisher had made significant progress in completing the respective business and acquisition strategies previously undertaken by each company and that it was appropriate in the current circumstances to give more consideration to whether a mutually agreeable transaction structure for a combination of Thermo and Fisher might be developed, and discussed generally the possible structure and terms of such a combination.
      In early April 2006, in connection with further discussions with Company B regarding potential areas of business collaboration, representatives of senior management of Company B indicated to representatives of Fisher that Company B would be interested in exploring a strategic business combination transaction with Fisher. In light of the discussions with Company A and developments in discussions with Thermo with respect to a possible business combination, representatives of Fisher senior management indicated to representatives of Company B senior management that if Company B had serious interest in a transaction it would have to make a compelling proposal to Fisher and be prepared to complete a transaction quickly. Thereafter, in early April 2006, representatives of Fisher and Company B met to discuss whether it was worthwhile exploring a strategic business combination, and whether Company B’s preliminary assumptions as to the nature and amount of synergies that might result from a combination were reasonable.
      At a meeting of the Fisher board of directors on April 11, 2006, representatives of senior management of Fisher reviewed the strategic alternatives potentially available to Fisher. Fisher’s financial advisors, Goldman Sachs and Lazard, discussed with the Fisher board financial information relating to each of Company A and Thermo. The board also discussed the potential strategic benefits and challenges posed by each of these alternatives, as well as the strategic direction and alternatives of Fisher generally. In addition, representatives of Skadden, Arps, Slate, Meagher & Flom LLP, Fisher’s outside legal advisor, discussed fiduciary duties applicable to the Fisher board of directors in the context of the ongoing discussions. After discussion, the consensus of the Fisher board was that senior management should continue its mutual due diligence and

18


Table of Contents

discussions with Company A, but also conduct further discussions with Thermo because, among other factors, Thermo and its management were well known to Fisher and a combination with Thermo appeared to present potentially strong strategic benefits in light of Thermo’s complementary business and significant opportunities for synergies and future growth. The Fisher board also reached a consensus that senior management of Fisher should explore further whether a possible strategic combination with Company B merited serious consideration.
      At a meeting of the Thermo board of directors held on April 12, 2006, representatives of Thermo senior management discussed the conversations between senior management of Thermo and Fisher, and there was a strong consensus among the Thermo directors that pursuing a transaction would be an attractive strategic and financial transaction for Thermo. Following this meeting, Thermo retained Lehman Brothers as its outside financial advisor and Wachtell, Lipton, Rosen & Katz as its outside legal advisor to advise Thermo in connection with this potential transaction. Subsequently, on April 13, 2006, Fisher and Thermo entered into a confidentiality agreement, and thereafter commenced mutual financial due diligence.
      Throughout the remainder of the month of April, representatives of Thermo and Fisher met to discuss a potential business combination transaction and to conduct mutual financial, legal and other customary due diligence.
      During the course of discussions between Fisher and Company A in mid-April 2006, Fisher advised Company A that Fisher was exploring a potential strategic transaction with another company. Subsequently, representatives of Company A advised representatives of Fisher that in light of Fisher’s exploration of other strategic transactions, Company A no longer wished to proceed with discussions with Fisher.
      In addition, during the period from mid- to late-April 2006, representatives of Fisher senior management continued discussions with representatives of Company B senior management as to whether it was worthwhile exploring a strategic business combination between the two companies, including general discussion of possible synergies.
      On April 25, 2006, the board of directors of Fisher met together with Fisher senior management and outside legal and financial advisors. Senior management reported to the board that Company A had terminated discussions regarding a possible transaction, and updated the board on the status of discussions with Thermo. Representatives of Goldman Sachs and Lazard discussed with the board financial information with respect to a potential transaction with Thermo. The board discussed the potential strategic benefits of such a transaction with Thermo, including the complementary aspects of the businesses of the two companies, the anticipated synergies that could result, and the opportunity for creation of long-term shareholder value for stockholders of the combined company. In addition, senior management of Fisher updated the board as to the exploratory discussions between Company B and Fisher, and representatives of Goldman Sachs and Lazard discussed with the Fisher board certain financial information with respect to Company B. After discussion, including discussion of the strategic rationale and potential for long-term value creation for Fisher stockholders presented by the alternatives, it was the sense of the Fisher board that a transaction with Thermo appeared to present an attractive strategic opportunity and it instructed management and its advisors to pursue actively such a transaction. The Fisher board also instructed senior management to continue exploratory discussions with Company B and to continue to consider whether a potential combination represented an opportunity that merited further consideration.
      Thereafter representatives of senior management of Fisher and Thermo continued their discussions. In addition, following a meeting in late April 2006 with representatives of Fisher as to potential synergies, representatives of Company B outlined the general framework within which it proposed to discuss a business combination transaction with Fisher, which would be subject to completion of due diligence and confirmation of its assumptions with respect to synergies.
      On April 27, 2006, the board of directors of Thermo met, together with Thermo management and outside legal and financial advisors. Senior management reported on the background of discussions with Fisher, proposed governance arrangements for the combined company that would result from any potential transaction and certain strategic considerations relating to the potential transaction. Representatives from

Lehman Brothers discussed each of Thermo and Fisher and their positions within their respective industries and certain financial information with respect to the potential transaction. Following questions and discussions among the participants at the meeting, the Thermo board of directors authorized and directed Thermo’s senior management and outside legal and financial advisors to continue discussions with Fisher.
      On May 1, 2006, the board of directors of Fisher met together with Fisher’s senior management. Senior management updated the Fisher board with respect to the status of discussions with Thermo and Company B. The Fisher board directed senior management to continue discussions with Thermo with a view to presenting a fully developed transaction to the board for consideration on May 7, 2006. In addition, the Fisher board authorized Fisher senior management to continue exploratory discussions with Company B.
      On May 2, 2006, the board of directors of Thermo met, together with Thermo’s management and outside legal and financial advisors. Management updated for the Thermo board of directors the status of discussions with Fisher, and reported on Thermo’s due diligence investigations of Fisher. Representatives from Lehman Brothers reported on certain preliminary financial analyses with respect to the proposed transaction, and representatives from Wachtell, Lipton discussed fiduciary duties applicable to the Thermo board of directors in the context of the proposed transaction. Following questions and discussions among those in attendance, Thermo’s board of directors authorized Thermo management to continue negotiations with Fisher and work toward finalizing definitive documentation regarding the potential transaction, and determined that the board of directors would meet on Sunday, May 7, 2006, to consider the proposed transaction. Also, on May 2, 2006, Thermo’s board of directors engaged Rothschild Inc. to act as an additional financial advisor to the board of directors in connection with the proposed transaction.
      During the first week of May 2006, Fisher and Thermo and their outside counsel continued to work to finalize the terms of the merger agreement and the related transaction documents, while continuing to conduct mutual financial, legal and other customary due diligence.
      On the morning of May 7, 2006, representatives of senior management of Thermo and Fisher met together with their respective financial advisors to finalize the exchange ratio and certain other terms of the proposed transaction. In this discussion, the parties agreed that the exchange ratio would be 2.0 shares of Thermo common stock for each outstanding share of Fisher common stock. The parties also agreed on the governance structure for the combined company that would result from the proposed transaction, with the board of directors of the combined company to consist of 5 Thermo designees and 3 Fisher designees.
      Also on the morning of May 7, 2006, the Fisher board of directors met with senior management and their outside legal and financial advisors. Representatives of Fisher senior management updated the Fisher board on the status of discussions with Thermo, including the discussions with Thermo earlier that morning, and management’s consideration of a potential business combination with Company B. Senior management and Fisher’s financial and legal advisors then discussed with the Fisher board the rationale, opportunities, benefits, prospects and risks associated with a potential transaction with Thermo based on the terms outlined in the proposed merger agreement. Senior management and Fisher’s financial and legal advisors also reviewed with the board the rationale, opportunities, benefits, prospects and risks associated with a potential transaction with Company B. Senior management also discussed the potential timing and process involved with respect to pursuing a transaction with each of Thermo and Company B. Representatives of Goldman Sachs and Lazard made a financial presentation to the board regarding the potential transaction with Thermo based on the terms of the transaction discussed that morning. Representatives of Skadden, Arps then summarized the terms of the merger agreement with Thermo and related documents, including those areas that were still under discussion, and also discussed fiduciary duties of the Fisher board of directors under the circumstances.
      After extensive discussion, including consideration of the matters discussed under “— Fisher’s Reasons for the Merger; Recommendation of the Merger by the Fisher Board of Directors,” the Fisher board of directors unanimously determined to proceed with a transaction with Thermo. The Fisher board reached a consensus that the proposed transaction with Thermo presented an attractive opportunity for Fisher stockholders, in light of, among other factors, the strong strategic rationale for the combination of Fisher and Thermo, the significant familiarity of the companies with one another, the confidence of Fisher senior management in the skills of Thermo senior management, and the expected benefits to Fisher stockholders of

owning stock of Thermo after a transaction. The Fisher board noted that a potential business combination transaction with Company B would not present as clear a strategic rationale as that present in the transaction with Thermo and remained subject to a number of significant uncertainties and contingencies. In addition, the board noted that a combination with Company B appeared to be significantly less attractive to Fisher and its stockholders than the transaction with Thermo and that even if Fisher continued negotiations with Company B, the transaction with Thermo would remain likely strategically and financially superior due to the highly complementary nature of the businesses and the related opportunities for synergies and potential for the creation of significant long-term value for Fisher stockholders. The board also discussed its concern that Thermo would terminate discussions if Fisher sought to delay execution of a definitive merger agreement to pursue further negotiations with Company B. The Fisher board of directors then instructed senior management and its legal advisors to finalize the terms of the merger agreement and related documentation with Thermo and instructed senior management to advise Company B that it intended to pursue a transaction with another party. Thereafter, the Fisher board of directors adjourned the meeting with a view to reconvening later in the day. Representatives of Fisher and its legal advisors then continued final negotiations with respect to a definitive merger agreement with representatives of Thermo and its legal advisors.
      Later in the day on May 7, 2006, the board of directors of Thermo met with senior management and their outside legal advisors and financial advisors. Management reviewed for the Thermo board of directors the background of discussions with Fisher and the progress of negotiations, and reported on Thermo’s due diligence investigations of Fisher. Lehman Brothers reviewed with the Thermo board of directors the structure and other indicated terms of the proposed transaction, and financial information regarding Fisher, Thermo and the transaction, as well as information regarding peer companies and comparable transactions. In connection with the deliberation by the Thermo board of directors, Lehman Brothers rendered to the Thermo board of directors its oral opinion (subsequently confirmed on May 7, 2006 in writing), as described under “— Opinion of Thermo’s Financial Advisor”, that, as of the date of its opinion, and subject to and based on the factors and assumptions set forth in its opinion, the exchange ratio to be paid by Thermo in the merger was fair, from a financial point of view, to Thermo.
      Representatives of Wachtell, Lipton discussed with the Thermo board of directors the legal standards applicable to its decisions and actions with respect to its evaluation of merger proposals, and reviewed the legal terms of the finalized merger proposal and the related agreements.
      Following these discussions, and review and discussion among the members of the Thermo board of directors, including consideration of the factors described under “— Thermo’s Reasons for the Merger; Recommendation of the Stock Issuance and Thermo Charter Amendment Proposals by the Thermo Board of Directors”, the Thermo board of directors unanimously determined that the transactions contemplated by the merger agreement, including the issuance of Thermo shares in connection with the merger and the Thermo charter amendment proposal, are advisable and in the best interests of Thermo and its stockholders, and the Thermo directors voted unanimously to approve the merger with Fisher and to approve and adopt the merger agreement.
      Late in the evening on May 7, 2006, the Fisher board of directors reconvened. Representatives of senior management of Fisher reported to the board that they had advised representatives of Company B that Fisher would likely be pursuing a business combination with another party and therefore would be terminating discussions with Company B. Management also updated the board with respect to discussions concerning certain terms of the merger agreement that had been finalized during the course of the day. Each of Goldman Sachs and Lazard rendered to the Fisher board of directors its oral opinion (subsequently confirmed on May 7, 2006 in writing), as described under “— Opinions of Fisher’s Financial Advisors”, that, as of the date of its opinion, and subject to and based on the qualifications and assumptions set forth in its opinion, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to the holders of Fisher common stock.
      Following these discussions, and further review and discussion among the members of the Fisher board of directors, the Fisher board of directors unanimously determined that the transactions contemplated by the merger agreement and the merger are advisable and fair to and in the best interests of Fisher and its

21

stockholders, and the Fisher directors voted unanimously to approve the merger and to approve and adopt the merger agreement.
      Thereafter the parties executed the merger agreement. The transaction was announced on the morning of May 8, 2006 in a press release issued jointly by Fisher and Thermo.
Thermo’s Reasons for the Merger; Recommendation of the Stock Issuance and Thermo Charter Amendment Proposals by the Thermo Board of Directors
      In reaching its decision to adopt and approve the merger agreement and recommend approval of the stock issuance and the Thermo charter amendment proposal to the Thermo stockholders, the Thermo board of directors consulted with Thermo’s management, as well as with its legal and financial advisors, and considered a number of factors, including the following factors which the Thermo board viewed as generally supporting its decision to approve the merger and the merger agreement and recommend the Thermo stockholders vote FOR approval of the issuance of Thermo common stock in connection with the merger and FOR the Thermo charter amendment proposal.
      Strategic Considerations. Thermo’s board believes the merger will provide a number of significant strategic opportunities, including the following:
  •  Thermo’s board believes that the combined company’s significantly broader product and services offerings will position it to better service customers by providing a complete set of solutions, and to respond more effectively to a number of industry dynamics, including increased marketplace competition;
 
  •  The significantly greater scale and scope of the combined company’s operations will better enable it to take advantage of growth opportunities, including in the areas of drug discovery, proteomics research, pharmacology services, molecular diagnostics, immunohistochemistry and environmental regulatory compliance;
 
  •  Fisher’s strong product set and well-recognized brands, as well as its global manufacturing and sales presence, will enhance Thermo’s ability to access customers, including in growing markets such as China and India;
 
  •  Fisher’s worldwide distribution and supply network will provide opportunities for increasing distribution efficiency, growing sales and introducing Thermo products to new markets;
 
  •  Thermo expects the combined company to achieve at least $75 million in cost savings in 2007, and approximately $200 million of cost savings and revenue opportunities in three years, coming from, among other things, rationalizing manufacturing operations, leveraging combined purchasing power, consolidating administrative activities, and pursuing revenue enhancing opportunities, such as cross-selling, entering new markets and developing new solutions;
 
  •  Thermo expects that the merger will result in a significant accretion to Thermo’s adjusted earnings per share; and
 
  •  Thermo anticipates cash flow from operations will increase, to over $1 billion annually, as a result of the transaction contemplated by the merger agreement and result in increased financial flexibility which will enhance Thermo’s ability to pursue strategic growth opportunities.
      Other Factors Considered by the Thermo Board. In addition to considering the strategic and financial factors described above, the Thermo board considered the following additional factors, all of which it viewed as supporting its decision to approve the merger:
  •  its knowledge of Thermo’s business, operations, financial condition, earnings and prospects and of Fisher’s business, operations, financial condition, earnings and prospects, taking into account the results of Thermo’s due diligence review of Fisher;
 
  •  the current and prospective competitive climate in the industries in which Thermo and Fisher operate, including the potential for consolidation, and the alternatives reasonably available to Thermo if it did not pursue the merger;

22


Table of Contents

  •  the financial analyses and presentations of Lehman Brothers, and its opinion, dated May 7, 2006, to the effect that, as of that date and based upon and subject to the factors and assumptions set forth in its opinion, the exchange ratio to be paid by Thermo in the merger was fair from a financial point of view to Thermo (see “— Opinion of Thermo’s Financial Advisor”);
 
  •  the terms and conditions of the merger agreement and the likelihood of completing the merger on the anticipated schedule;
 
  •  the governance agreements with respect to the combined company post-merger, as described under “— Board of Directors and Management Following the Merger”, including the fact that Mr. Dekkers will serve as President and Chief Executive Officer of the combined company, and the board will consist of five Thermo designees and three Fisher designees;
 
  •  the fact that the exchange ratio represented a premium to Fisher stockholders of approximately 7% based on the closing prices of each company’s stock on the NYSE on May 5, 2006, the last trading day before the merger was publicly announced, and that the exchange ratio is fixed, which the Thermo board believed was consistent with market practice for mergers of this type and with the strategic purpose of the merger; and
 
  •  the anticipated market capitalization, adjusted price/earnings ratio and capital structure of the combined company.
      The Thermo board of directors weighed these advantages and opportunities against a number of other factors identified in its deliberations weighing negatively against the merger, including:
  •  the challenges inherent in the combination of two businesses of the size and scope of Thermo and Fisher and the possible diversion of management attention for an extended period of time;
 
  •  the risk of not capturing all the anticipated cost savings and operational synergies between Thermo and Fisher and the risk that other anticipated benefits might not be realized;
 
  •  the risk that regulatory agencies may not approve the merger or may impose terms and conditions on their approvals that adversely affect the projected financial results of the combined company; See the section entitled “— Regulatory Approvals Required for the Merger”; and
 
  •  the risks of the type and nature described under “Risk Factors”, and the matters described under “Cautionary Statement Regarding Forward-Looking Statements”.
      In view of the wide variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, the Thermo board of directors did not find it useful and did not attempt to quantify or assign any relative or specific weights to the various factors that it considered in reaching its determination to approve the merger and the merger agreement and to recommend that Thermo stockholders vote FOR the issuance of Thermo common stock in connection with the merger and FOR the Thermo charter amendment proposal. In addition, individual members of the Thermo board of directors may have given differing weights to different factors. The Thermo board of directors conducted an overall analysis of the factors described above, including through discussions with, and questioning of, Thermo’s management and outside legal and financial advisors.
      The Thermo board of directors unanimously determined that the merger, the merger agreement and the transactions contemplated by the merger agreement, including the stock issuance and the Thermo charter amendment, are advisable and in the best interests of Thermo and its stockholders and unanimously approved the merger agreement. The Thermo board unanimously recommends that Thermo stockholders vote “FOR” the issuance of Thermo common stock in connection with the merger and “FOR” the Thermo charter amendment proposal.
Fisher’s Reasons For the Merger; Recommendation of the Merger by the Fisher Board of Directors
      At a special meeting of the Fisher board of directors on May 7, 2006, after careful consideration, including consultation with Fisher’s management and its financial and legal advisors, the Fisher board

Table of Contents

unanimously determined that the merger agreement and the merger are advisable and fair to and in the best interests of Fisher and its stockholders and that the board shall recommend that the Fisher stockholders vote FOR the approval and adoption of the merger agreement. In arriving at its determination, the Fisher board considered a number of factors, including the following material factors, which the Fisher board viewed as generally supporting its determination:
  •  the complementary aspects of the respective businesses of Fisher and Thermo, including that the combined company is expected to create a provider of fully integrated, end-to-end solutions in the life, laboratory and health sciences industry for its customers;
 
  •  the potential financial benefits of the merger and significant opportunities for the creation of long-term value for Fisher stockholders, including:
  •  that the merger is expected to result in a 20% compound annual growth rate in adjusted earnings per share over three years;
 
  •  that the transaction is expected to generate approximately $200 million in cost and revenue synergies over three years, including:
  •  at least $75 million expected in 2007;
 
  •  $150 million of cost-related synergies, excluding one-time costs, expected to result primarily from manufacturing rationalization, sourcing and logistics efficiencies, and shared administrative functions; and
 
  •  $50 million of revenue-related synergies expected to result from cross-selling opportunities, enhanced geographic reach, penetration of new and existing markets, and new solutions development;
  •  that the cash flow from operations of the combined company is expected to be in excess of $1 billion in 2007, making the combined company well-positioned to accelerate growth both organically and through acquisitions;
  •  the conditions in the life, laboratory and health sciences industry generally and the business, prospects, financial performance and condition, operations, management and competitive position of Fisher on a stand-alone basis as compared to the positions of the combined company after giving effect to the merger;
 
  •  historical information concerning Fisher’s and Thermo’s respective businesses, prospects, financial performance and condition, operations, management and competitive position, including information contained in public reports concerning results of operations during the most recent fiscal year and fiscal quarter for each of Fisher and Thermo filed with the SEC, as well as reports from Fisher’s management and Fisher’s legal advisors as to the results of the due diligence investigation of Thermo;
 
  •  Fisher management’s view of the businesses, prospects, financial performance and condition, operations, management and competitive position of Fisher and Thermo before the merger, and of the combined company after giving effect to the merger;
 
  •  that the combination of Fisher and Thermo is expected to benefit customers and suppliers, and provide greater opportunities for the employees of the combined company;
 
  •  current financial market conditions and historical market prices, volatility and trading information with respect to Fisher’s common stock and Thermo’s common stock;
 
  •  that stockholders of Fisher immediately prior to the merger will own approximately 61% of the combined company immediately following the merger and will therefore participate meaningfully in the significant opportunities for long-term growth of the combined company;

24


Table of Contents

  •  that senior management of Thermo is well known to senior management of Fisher and that senior management of Fisher expressed confidence in the ability of senior management to successfully manage the combined company and to achieve long-term value for its stockholders;
 
  •  the opinion of each of Goldman Sachs and Lazard to the effect that, as of May 7, 2006 and based upon and subject to the factors and assumptions set forth therein, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to the holders of Fisher common stock. See the section entitled “— Opinions of Fisher’s Financial Advisors”;
 
  •  the opportunity for Fisher stockholders to benefit from any increase in the trading price of Thermo common stock between the announcement of the merger and the completion of the merger because the exchange ratio is a fixed number of shares of Thermo common stock;
 
  •  the expected qualification of the merger as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code, resulting in the merger consideration to be received by Fisher stockholders not being subject to federal income tax, as described in the section entitled “— Material U.S. Federal Income Tax Consequences of the Merger”; and
 
  •  the belief that the terms of the merger agreement are reasonable, including:
  •  the limited conditions to the parties’ respective obligations to complete the merger;
 
  •  that Paul M. Meister, Vice Chairman of the Fisher board of directors, will become the non-executive Chairman of the board of directors of the combined company;
 
  •  that Marijn E. Dekkers, President and Chief Executive Officer of Thermo, will continue to serve as the President and Chief Executive Officer of the combined company and that Mr. Dekkers has agreed to waive the acceleration of certain change of control benefits to which he would otherwise have been entitled in connection with the merger;
 
  •  that the combined company’s board of directors will include at least three members nominated by Fisher for a period of at least three years;
 
  •  that each party has agreed to not solicit proposals relating to alternative business combination transactions or, subject to certain exceptions, enter into discussions or an agreement concerning or provide confidential information in connection with any proposals for alternative business combination transactions;
 
  •  that, unless the merger agreement is terminated in accordance with its terms, stockholders of Fisher and Thermo will have the opportunity to vote on approval and adoption of the merger agreement and related matters, taking into consideration that while the ability of Fisher stockholders to consider an alternative transaction may therefore be delayed or prevented, the ability of Thermo stockholders to consider an alternative transaction may similarly be delayed or prevented;
 
  •  that the merger agreement contains certain termination rights for both Fisher and Thermo and that upon termination of the merger agreement under specified circumstances, Fisher may be required to pay Thermo a termination fee of $300 million or Thermo may be required to pay Fisher a termination fee of $200 million; and
 
  •  that Thermo will establish a long-term incentive compensation program for Thermo senior management and that there will also be appropriate continuing performance incentives for senior management of Fisher who will continue with the combined company.
      In addition to these factors, the Fisher board identified and considered a variety of risks and potentially negative factors in its deliberations concerning the merger, including:
  •  the possibility that the merger might not be consummated, or that consummation might be unduly delayed or subject to conditions that may be imposed by governmental authorities;

25


Table of Contents

  •  the effect of public announcement of the merger on Fisher’s revenues, operating results, the price of its common stock and Fisher’s ability to attract and retain customers and key employees;
 
  •  the risk that the potential benefits sought in the merger might not be fully realized;
 
  •  the substantial charges to be incurred in connection with the merger, including costs of integrating the businesses and transaction expenses arising from the merger;
 
  •  the risk that despite the efforts of the combined company, key employees might not remain employed by the combined company;
 
  •  because the exchange ratio is a fixed number of shares of Thermo common stock, the possibility that Fisher stockholders could be adversely affected by a decrease in the trading price of Thermo common stock between the date of announcement of execution of the merger agreement and the closing of the merger, and the fact that the merger agreement does not provide Fisher with a price-based termination right or other similar protection;
 
  •  the limitations imposed in the merger agreement on the solicitation or consideration by Fisher and Thermo of alternative business combinations prior to the completion of the merger;
 
  •  the fact that upon termination of the merger agreement under specified circumstances, Fisher may be required to pay Thermo a termination fee of $300 million and this termination fee may discourage other parties that may otherwise have an interest in a business combination with, or an acquisition of, Fisher;
 
  •  the terms of the merger agreement restricting the conduct of Fisher’s business during the period between execution of the merger agreement and the completion of the merger; and
 
  •  the interests that certain executive officers and directors of Fisher may have with respect to the merger in addition to their interests as stockholders of Fisher generally, as described in the section entitled “— Financial Interests of Directors and Officers in the Merger”, which the Fisher board considered to be neutral in its evaluation of the proposed transaction.
      The above discussion of the material factors considered by the Fisher board of directors is not intended to be exhaustive, but does set forth the principal factors considered by the Fisher board. The Fisher board unanimously reached the conclusion to approve and adopt the merger agreement and the other transactions contemplated by the merger agreement and to recommend the merger agreement to the Fisher stockholders for approval and adoption in light of the various factors described above and other factors that each member of the Fisher board felt were appropriate. In view of the wide variety of factors considered by the Fisher board in connection with its evaluation of the merger and the complexity of these matters, the Fisher board did not consider it practical, and did not attempt, to quantify, rank or otherwise assign relative weights to the specific factors it considered in reaching its decision. Rather, the Fisher board made its recommendation based on the totality of information presented to, and the investigation conducted by, it. In considering the factors discussed above, individual directors may have given different weights to different factors.
      The Fisher board unanimously approved and adopted the merger agreement and the other transactions contemplated by the merger agreement and recommends that the Fisher stockholders vote “FOR” the approval and adoption of the merger agreement.
Opinion of Thermo’s Financial Advisor
      On May 7, 2006, Lehman Brothers delivered its oral opinion, which was subsequently confirmed in writing as of such date, to the Thermo board of directors to the effect that as of such date and, based upon and subject to factors and assumptions described at the meeting of the Thermo board of directors on May 7, 2006 and set forth in the written opinion, the exchange ratio to be paid by Thermo in the merger was fair, from a financial point of view, to Thermo.
      The full text of Lehman Brothers’ written opinion, dated May 7, 2006, is attached hereto as Annex B. Thermo stockholders are urged to read this opinion for a discussion of the assumptions made, procedures

followed, factors considered and limitations upon the review undertaken by Lehman Brothers in rendering its opinion. The following is a summary of Lehman Brothers’ opinion and the methodologies that Lehman Brothers used to render its fairness opinion. The summary is qualified in its entirety by reference to the full text of the opinion.
      Lehman Brothers’ advisory services and opinion were provided for the information and assistance of the Thermo board of directors in connection with its consideration of the proposed transaction. Lehman Brothers’ opinion is not intended to be and does not constitute a recommendation to any stockholder of Thermo or Fisher as to how such stockholder should vote in connection with the proposed transaction. Lehman Brothers was not requested to opine as to, and Lehman Brothers’ opinion does not address, Thermo’s underlying business decision to proceed with or effect the proposed transaction.
      In arriving at its opinion, Lehman Brothers reviewed and analyzed:
  •  the merger agreement and the specific terms of the proposed transaction (including with respect to governance of the combined company);
 
  •  publicly available information concerning Thermo that Lehman Brothers believed to be relevant to its analysis, including Thermo’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and Thermo’s Quarterly Report on Form 10-Q for the quarter ended April 1, 2006;
 
  •  publicly available information concerning Fisher that Lehman Brothers believed to be relevant to its analysis, including Fisher’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and Fisher’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2006;
 
  •  financial and operating information with respect to the business, operations and prospects of Thermo furnished to Lehman Brothers by Thermo, including financial estimates and forecasts for Thermo prepared by Thermo’s management;
 
  •  financial and operating information with respect to the business, operations and prospects of Fisher furnished to Lehman Brothers by Fisher, including financial estimates and forecasts for Fisher prepared by Fisher’s management;
 
  •  the trading histories of Thermo common stock and Fisher common stock from May 6, 2005 to May 5, 2006 and a comparison of those trading histories with each other and with those of other companies and indices that Lehman Brothers deemed relevant;
 
  •  a comparison of the historical financial results and present financial condition of Thermo and Fisher with each other and with those of other companies that Lehman Brothers deemed relevant;
 
  •  published estimates of independent research analysts with respect to ratings and future price targets of Thermo common stock and Fisher common stock;
 
  •  the relative contributions of Thermo and Fisher to the historical and future financial condition and performance of the combined company on a pro forma basis;
 
  •  the potential pro forma impact of the proposed transaction on the future financial condition and performance of Thermo, including estimated cost savings, operating synergies and other strategic benefits that the managements of Thermo and Fisher anticipated would result from a combination of the businesses of Thermo and Fisher, referred to as the estimated synergies, and the anticipated impact of the proposed transaction on Thermo’s pro forma adjusted earnings per share; and
 
  •  a comparison of the financial terms of the proposed transaction with the financial terms of certain other transactions that Lehman Brothers deemed relevant.
      In addition, Lehman Brothers had discussions with the managements of Thermo and Fisher concerning their respective businesses, operations, assets, liabilities, financial conditions and prospects and undertook such other studies, analyses and investigations as Lehman Brothers deemed appropriate.

27


Table of Contents

      In arriving at its opinion, Lehman Brothers assumed and relied upon the accuracy and completeness of the financial and other information used by it without assuming any responsibility for independent verification of such information and further relied upon the assurances of managements of Thermo and Fisher that they were not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to forecasts and estimates prepared by Thermo’s management and Fisher’s management, upon advice of Thermo, Lehman Brothers assumed that these forecasts and estimates were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the managements of Thermo and Fisher as to the future financial performance of Thermo and Fisher and that Thermo and Fisher will perform substantially in accordance with these forecasts and estimates. Upon the advice of Thermo and Fisher, Lehman Brothers also assumed that the estimated synergies will be realized substantially in accordance with such estimates.
      In arriving at its opinion, Lehman Brothers did not conduct a physical inspection of the properties and facilities of Thermo and Fisher and did not make or obtain any evaluations or appraisals of the assets or liabilities of Thermo or Fisher. Lehman Brothers’ opinion necessarily was based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date of Lehman Brothers’ opinion. Lehman Brothers expressed no opinion as to the prices at which shares of Thermo common stock will trade at any time following the announcement or the consummation of the proposed transaction. Although Lehman Brothers evaluated the fairness, from a financial point of view, to Thermo of the exchange ratio to be paid by Thermo in the proposed transaction, Lehman Brothers was not requested to, and did not, recommend the specific exchange ratio to be paid in the proposed transaction, which was determined through negotiations between Thermo and Fisher.
      In connection with rendering its opinion, Lehman Brothers performed certain financial, comparative and other analyses as summarized below. In arriving at its opinion, Lehman Brothers did not ascribe a specific range of values to Thermo or Fisher, but rather made its determination as to the fairness, from a financial point of view, to Thermo of the exchange ratio to be paid by Thermo on the basis of financial, comparative and other analyses. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial and comparative analysis and the application of those methods to the particular circumstances. Therefore, such an opinion is not readily susceptible to summary description. Furthermore, in arriving at its opinion, Lehman Brothers did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Lehman Brothers believes that its analyses must be considered as a whole and that considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion. In its analyses, Lehman Brothers made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Thermo and Fisher. Because these assumptions are inherently subject to uncertainty, none of Thermo, Fisher, Lehman Brothers or any other person assumes responsibility if future results are materially different from those forecast. Any estimates contained in these analyses were not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth in these analyses. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses actually may be sold.
      The following is a summary of the material financial analyses used by Lehman Brothers in connection with providing its opinion to the Thermo board of directors. Certain of the summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses used by Lehman Brothers, 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. Accordingly, the analyses listed in the tables and described below must be considered as a whole. Considering any portion of such analyses and of the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the results of Lehman Brothers’ opinion.

  Comparable Company Analysis
      In order to assess how the public market values shares of similar publicly-traded companies, Lehman Brothers reviewed and compared specific financial and operating data relating to Thermo and Fisher and the nine companies in the Life and Laboratory Supplier Index. Using internal estimates and forecasts prepared by Thermo management for Thermo, internal estimates and forecasts prepared by Fisher management for Fisher, and publicly available information for the other companies, Lehman Brothers calculated and analyzed the ratios of each company’s May 5, 2006 stock price to its estimated earnings per share on both a reported and adjusted basis (adjusted earnings per share excluded expenses related to the amortization of intangibles),

referred to as a price earnings ratio, or P/ E, for calendar years 2006 and 2007 and the ratios of each company’s enterprise value to calendar years 2006 and 2007 earnings before interest, taxes, depreciation and amortization, referred to as EBITDA. The enterprise value of each company was obtained by adding its short and long-term debt to, and subtracting its cash from, the sum of the market value of its diluted common equity as of May 5, 2006, the value of any preferred stock (at liquidation value), the book value of any minority interest and the value of any material debt-equivalent liabilities.

      However, given the inherent differences between the business, operations and prospects of Thermo and Fisher and the business, operations and prospects of the companies included in the comparable company analysis, Lehman Brothers believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the comparable company analysis and accordingly also made qualitative judgments concerning differences between the financial and operating characteristics and prospects of Thermo and Fisher and the companies included in the comparable company analysis that would affect the public trading values of each. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between Thermo, Fisher and the selected comparable companies.
Equity Research Analysts
      Lehman Brothers considered publicly available price targets published by various firms that publish independent research on Thermo (including Deutsche Bank Securities Inc., Infinium Capital Corp., JPMorgan Chase & Co., Leerink Swann & Co., Lehman Brothers Inc., Merrill Lynch & Co. Inc., Needham & Company, LLC., Robert W. Baird & Co. Inc., and UBS Securities LLC) and Fisher (including Banc of America Securities LLC., Deutsche Bank Securities Inc., First Analysis Securities Corp., The Goldman Sachs Group, Inc., Infinium Capital Corp., JPMorgan Chase & Co., Leerink Swann & Co., Lehman Brothers Inc., Merrill Lynch & Co. Inc., Morgan Stanley & Co. Inc., Robert W. Baird & Co. Inc., Thomas Weisel Partners LLC., and UBS Securities LLC) in order to determine the exchange ratio implied by such research. The following table shows the range of implied exchange ratios using the Thermo and Fisher share price targets as published by various firms:

Comparable Transaction Analysis
      Lehman Brothers reviewed 14 acquisitions of companies that Lehman Brothers, based on its experience with merger and acquisition transactions, deemed comparable to the proposed transaction. Lehman Brothers selected the transactions used in the comparable transaction analysis based on the similarity of the target

      Based on publicly available information, Lehman Brothers considered, among other things, the enterprise values of each target company as a multiple of the EBITDA of the target company in each case for the latest 12 months, which is referred to as LTM, prior to the date that the transaction was announced. The following table sets forth the results of this analysis:

      Because the market conditions, rationale and circumstances surrounding each of the transactions analyzed were specific to each transaction, and because of the inherent differences between the businesses, operations and prospects of Thermo and Fisher and the businesses, operations and prospects of the acquired companies included in the comparable transaction analysis, Lehman Brothers believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the comparable transaction analysis and accordingly also made qualitative judgments concerning differences between the financial and operating characteristics and prospects of Thermo and Fisher and the companies included in the comparable transaction analysis that would affect the transaction values of each.
Discounted Cash Flow Analysis
      Lehman Brothers performed a discounted cash flow analysis of Thermo and Fisher to calculate the estimated present values of Thermo common stock and Fisher common stock. A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the “present value” of estimated future cash flows of the asset. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macro-economic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors applicable to a particular asset. The estimated present values of Thermo

31


Table of Contents

common stock and Fisher common stock were calculated by adding the present values of the estimated free cash flow estimates for the fiscal years 2006 through 2010 for each of Thermo and Fisher. The cash flow estimates for 2006 and 2007 were based on internal estimates and forecasts prepared by Thermo management for Thermo and internal estimates and forecasts prepared by Fisher management for Fisher, and the information for 2008 through 2010 was based on extrapolation after consultation with Thermo management.
      To estimate the residual value of Thermo and Fisher at the end of the forecast period, or terminal value, Lehman Brothers applied a range of terminal value multiples based on estimated calendar 2010 EBITDA of 13.5x to 15.5x for Thermo and 10.5x to 12.5x for Fisher and discount rates ranging from 8.5% to 10.5%. The discount rates used were based on an analysis of Thermo’s and Fisher’s weighted average cost of capital and those of other comparable companies.
      Based upon these terminal values and discount rates, Lehman Brothers calculated a range of implied equity values per share of Thermo and Fisher common stock, which were then used to calculate a range of implied exchange ratios. Based on these implied per share values, this analysis indicated the following implied exchange ratio range, as compared to the exchange ratio in the proposed transaction:
     
Implied Exchange Ratio Range
  1.484x - 2.256x
Proposed Transaction
  2.000x
Contribution Analysis
      Lehman Brothers analyzed the respective contributions of Thermo and Fisher to certain income statement metrics for the combined company for calendar years 2006 and 2007, using internal estimates and forecasts prepared by Thermo management for Thermo and internal estimates and forecasts prepared by Fisher management for Fisher. The proportionate contributions were calculated taking into account Thermo’s and Fisher’s respective current debt and cash levels and compared to the pro forma ownership of the combined company by Thermo and Fisher stockholders as a result of the proposed transaction. Based on the implied diluted equity ownership of each of Thermo and Fisher stockholders of the combined company, Lehman Brothers calculated a range of implied exchange ratios. The following table sets forth the results of this analysis:

Pro Forma Analysis
      Lehman Brothers analyzed the pro forma impact of the proposed transaction on the future financial condition and performance of Thermo, reflected in the pro forma earnings per share of Thermo. For purposes of this analysis, Lehman Brothers utilized internal estimates and forecasts prepared by Thermo management for Thermo and internal estimates and forecasts prepared by Fisher management for Fisher, as well as the estimated synergies. This analysis indicated that the proposed transaction would be accretive to Thermo’s calendar year 2007 adjusted earnings per share. The financial forecasts and assumptions that underlie this analysis are subject to substantial uncertainty and exclude one-time costs that may be incurred in connection with the implementation of the expected synergies and, therefore, actual results may be substantially different.
Illustrative Trading Prices Analysis
      Lehman Brothers calculated illustrative implied per share price ranges of the combined company following consummation of the proposed transaction. The analysis was based on a 2.0 exchange ratio to be paid by Thermo in the proposed transaction, a range of synergies from $75 million to $200 million, which represents the synergies estimated by the managements of Thermo and Fisher to be realized in calendar year 2007 and the total synergies to be realized in connection with the proposed transaction, respectively. Based on an adjusted P/E multiple range of 15.3x to 19.9x (which is based upon the current P/E multiples of Fisher and Thermo, respectively) the analysis resulted in implied trading prices per share of Thermo common stock ranging from $35.34 to $49.95.
Miscellaneous
      Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. Thermo’s board of directors selected Lehman Brothers because of its expertise, reputation and familiarity with Thermo and the life and laboratory supply industry generally, and because its investment banking professionals have substantial experience in transactions comparable to the proposed transaction.
      As compensation for its services in connection with the proposed transaction, Thermo has agreed to pay Lehman Brothers a fee of $17 million, a portion of which was due upon delivery of Lehman Brothers’ opinion and the remainder of which is contingent upon the consummation of the proposed transaction, plus an additional fee of up to $5 million, which is payable at Thermo’s sole discretion. In addition, Thermo has agreed to reimburse Lehman Brothers for reasonable out-of-pocket expenses incurred in connection with the proposed transaction and to indemnify Lehman Brothers for certain liabilities that may arise out of its engagement by Thermo and the rendering of Lehman Brothers’ opinion.
      Lehman Brothers also provided a $1.5 billion 364-day credit facility to be used by Thermo for the potential refinancing of certain of Fisher’s and Thermo’s indebtedness in connection with the proposed transaction, for which Lehman Brothers expects to receive customary fees. Lehman Brothers has also performed various investment banking services for Thermo in the past and expects to perform various investment banking services for Thermo in the future and has received, and expects to receive, customary fees for such services. In the ordinary course of its business, Lehman Brothers may actively trade in the debt and equity securities of Thermo and Fisher for its own account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities.

matters considered and limitations on the reviews undertaken by Goldman Sachs and Lazard in rendering their respective opinions.
  Opinion of Goldman Sachs
      Goldman Sachs rendered its opinion to the Fisher board of directors that, as of May 7, 2006 and based upon and subject to the assumptions, procedures, factors, limitations and qualifications set forth in such opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to the holders of Fisher common shares.
      The full text of the written opinion of Goldman Sachs, dated May 7, 2006, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with its opinion, is attached as Annex C to this document and is incorporated herein by reference. Fisher stockholders should read the opinion in its entirety. Goldman Sachs provided its opinion for the information and assistance of the Fisher board of directors in connection with its consideration of the merger. The Goldman Sachs opinion is not a recommendation as to how any holder of Fisher common stock or Thermo common stock should vote at any stockholders’ meeting to be held in connection with, or take any action with respect to, the merger.
      In connection with rendering its opinion described above and performing its related financial analyses, Goldman Sachs has reviewed, among other things:
  •  the merger agreement;
 
  •  annual reports to stockholders and Annual Reports on Form 10-K of Fisher and Thermo for the five years ended December 31, 2005;
 
  •  certain interim reports to stockholders and Quarterly Reports on Form 10-Q of Fisher and Thermo;
 
  •  certain other communications from Fisher and Thermo to their respective stockholders;
 
  •  certain internal financial analyses and forecasts for Thermo prepared by its management;
 
  •  certain internal financial analyses and forecasts for Thermo prepared by its management, reviewed and revised by the management of Fisher, and certain internal financial analyses and forecasts for Fisher prepared by its management; and
 
  •  certain cost savings and operating synergies projected by the respective managements of Fisher and Thermo to result from the merger.
      Goldman Sachs also held discussions with members of the senior managements of Fisher and Thermo regarding their assessment of the strategic rationale for, and the potential benefits of, the merger and the past and current business operations, financial condition, and future prospects of Fisher and Thermo. In addition, Goldman Sachs reviewed the reported price and trading activity for the shares of Fisher common stock and the shares of Thermo common stock, compared certain financial and stock market information for Fisher and Thermo with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the healthcare industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as it considered appropriate.
      Goldman Sachs has relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by it and assumed such accuracy and completeness for purposes of rendering the opinion described above and did not assume any responsibility for any independent verification of such information. In that regard, Goldman Sachs assumed with the consent of the Fisher board of directors that the financial forecasts and the cost savings and operating synergies projected by Fisher and Thermo, were reasonably prepared on a basis reflecting the best currently available estimates and judgments of management of Fisher and Thermo. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and

34


Table of Contents

liabilities) of Fisher or Thermo or any of their respective subsidiaries and no such evaluation or appraisal was furnished to Goldman Sachs.
      Goldman Sachs’ opinion did not address the underlying business decision of Fisher to engage in the merger, nor did Goldman Sachs express any opinion as to the prices at which shares of Fisher common stock or Thermo common stock will trade at any time. Goldman Sachs also assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect on Fisher or Thermo or on the expected benefits of the merger in any way meaningful to its analyses. Goldman Sachs’ opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available as of, the date therein.
      Goldman Sachs’ advisory services and opinion were provided for the information and assistance of the Fisher board of directors in connection with its consideration of the merger and its opinion did not constitute a recommendation as to how any holder of Fisher common shares should vote with respect to the merger.
      See “— Financial Analyses of Fisher’s Financial Advisors” below for a summary of the material financial analyses used by Goldman Sachs in connection with rendering its opinion.
      Goldman Sachs and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. Goldman Sachs is currently providing and has provided certain investment banking services to Fisher from time to time, including having acted as:
  •  a lead manager in connection with the offering of 2.50% Convertible Senior Notes due October 2023 (aggregate principal amount $250,000,000) in July 2003;
 
  •  financial advisor with respect to Fisher’s acquisition of Dharmacon Inc. in February 2004;
 
  •  a lead manager in connection with the offering of 3.25% Convertible Senior Subordinated Notes due March 1, 2024 (aggregate principal amount $300,000,000) in March 2004;
 
  •  financial advisor with respect to Fisher’s acquisition of Apogent Technologies in March 2004;

      In addition, Goldman Sachs’s commercial bank affiliate is a lender under bank loans of Fisher.
      Goldman Sachs may also provide investment banking and other services to Fisher and Thermo in the future. In connection with the above-described services performed by it, Goldman Sachs received, and with respect to services in the future would expect to receive, compensation.
      Goldman Sachs is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman Sachs and its affiliates may provide such services to Fisher and Thermo and their respective affiliates and may actively trade the debt or equity securities (or related derivative securities) of Fisher or Thermo for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.
      The Fisher board of directors selected Goldman Sachs as one of its financial advisors because Goldman Sachs is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement dated March 16, 2006, Fisher engaged Goldman Sachs to act as a financial advisor in connection with the merger. Pursuant to the terms of this engagement letter, Fisher has agreed to pay Goldman Sachs a transaction fee of $22,000,000, $6,600,000 of which became

35

payable upon the execution of the merger agreement and the remainder of which is payable upon consummation of the merger. In addition, Fisher has agreed to reimburse Goldman Sachs’ expenses incurred in connection with this engagement and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.
  Opinion of Lazard
      Lazard rendered its opinion to the Fisher board of directors that, as of May 7, 2006 and based upon and subject to the assumptions, procedures, factors, limitations and qualifications set forth in such opinion, the exchange ratio pursuant to the merger was fair from a financial point of view to the holders of Fisher common stock.
      The full text of the written opinion of Lazard, dated May 7, 2006, which sets forth assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with its opinion, is attached as Annex D to this document and is incorporated herein by reference. Fisher stockholders should read the opinion in its entirety. Lazard provided its opinion for the information and assistance of the Fisher board of directors in connection with its consideration of the merger. Lazard’s opinion is not a recommendation as to how any holder of Fisher common stock or Thermo common stock should vote at any stockholders’ meeting to be held in connection with, or take any action with respect to, the merger.
      In connection with rendering its opinion described above and performing its related financial analyses, Lazard:
  •  reviewed the financial terms and conditions of the latest draft of the merger agreement;
 
  •  analyzed certain historical business and financial information relating to Fisher and Thermo;
 
  •  reviewed various financial forecasts and other data provided to it by Fisher and Thermo relating to their respective businesses;
 
  •  reviewed the synergistic savings and benefits and the timing of their occurrence as projected by Fisher and Thermo to be realized by the combined company following the merger;
 
  •  held discussions with members of the senior managements of Fisher and Thermo with respect to the businesses and prospects of Fisher and Thermo, respectively, the strategic objectives of each, and synergistic savings and benefits projected by Fisher and Thermo to be realized by the combined company following the merger;
 
  •  reviewed public information with respect to certain other companies in lines of business it believed to be generally comparable to those of Fisher and Thermo;
 
  •  reviewed the financial terms of certain business combinations involving companies in lines of business it believed to be generally comparable to those of Fisher and Thermo;
 
  •  reviewed the historical stock prices and trading volumes of Fisher common stock and Thermo common stock; and
 
  •  conducted such other financial studies, analyses and investigations as it deemed appropriate.
      Lazard relied upon the accuracy and completeness of the foregoing information and did not assume any responsibility for any independent verification of such information or any independent valuation or appraisal of any of the assets or liabilities of Fisher or Thermo, or concerning the solvency or fair value of Fisher or Thermo. In that regard, Lazard assumed with the consent of the Fisher board of directors that the financial forecasts, including the synergistic savings and benefits projected by Fisher and Thermo to be realized following the merger and the timing of their occurrence, were reasonably prepared on bases reflecting the best currently available estimates and judgments of management of Fisher and Thermo as to the future financial performance of Fisher and Thermo, respectively, and of both Fisher and Thermo with respect to the combined

Table of Contents

company. Lazard assumed no responsibility for, and expressed no view as to, the financial forecasts or the assumptions on which they are based.
      In rendering its opinion, Lazard assumed that the merger will be consummated on the terms described in the latest draft of the merger agreement reviewed by Lazard, without any waiver or modification of any material terms or conditions, that obtaining the necessary regulatory approvals for the merger will not have an adverse effect on Fisher, Thermo or the combined company, and that the synergistic savings and benefits of the merger projected by Fisher and Thermo will be substantially realized both in scope and timing. In addition, Lazard assumed that the representations and warranties of Fisher and Thermo contained in the draft merger agreement were true and complete and that the merger will be accounted for as a tax-free “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code.
      Lazard’s opinion did not address the merits of the underlying business decision of Fisher to engage in the merger or the relative merits of the merger as compared to other business strategies or transactions that might be available to Fisher. Lazard did not express any opinion as to any tax or other consequences that might result from the merger, nor did its opinion address any legal, tax, regulatory or accounting matters, as to which Lazard understood that Fisher obtained such advice as it deemed necessary from qualified professionals. Lazard did not express any opinion as to the prices at which shares of Fisher common stock or Thermo common stock would trade at any time. Lazard’s opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available as of, the date therein. Lazard assumed no responsibility for updating or revising its opinion based on circumstances or events occurring after the date thereof.
      Lazard’s advisory services and opinion were provided for the information and assistance of the Fisher board of directors in connection with its consideration of the merger and its opinion did not constitute a recommendation as to how any holder of Fisher common shares should vote at any stockholders’ meeting to be held in connection with, or take any action with respect to, the merger.
      See “— Financial Analyses of Fisher’s Financial Advisors” below for a summary of the material financial analyses used by Lazard in connection with rendering its opinion.
      Lazard and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. Lazard has in the past provided investment banking services to Fisher, for which Lazard received customary fees. Lazard may provide investment banking or other services to Fisher and Thermo in the future and would expect to receive customary compensation. In addition, in the ordinary course of their respective businesses, affiliates of Lazard and LFCM Holdings LLC (an entity indirectly held in large part by managing directors of Lazard) may actively trade securities of Fisher or Thermo for their own accounts and for the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities.
      The Fisher board of directors selected Lazard as one of its financial advisors because Lazard is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement dated May 6, 2006, Fisher engaged Lazard to act as a financial advisor in connection with the merger. Pursuant to the terms of this engagement letter, Fisher has agreed to pay Lazard a transaction fee of $22,000,000, $6,000,000 of which became payable upon the execution of the merger agreement and the remainder of which is payable upon consummation of the merger. In addition, Fisher has agreed to reimburse Lazard’s expenses in connection with this engagement and to indemnify Lazard and related persons against various liabilities, including certain liabilities under the federal securities laws.
  Financial Analyses of Fisher’s Financial Advisors
      The following is a summary of the material financial analyses used by Goldman Sachs and Lazard, which are sometimes referred to collectively as the Fisher financial advisors, in connection with rendering their

respective opinions described above. The following summary, however, does not purport to be a complete description of the financial analyses performed by the Fisher financial advisors. The order of analyses described does not represent relative importance or weight given to those analyses by either of the Fisher financial advisors. Some of the summaries of the financial analyses include information presented in tabular format. The tables must be read together with the full text of each summary and are alone not a complete description of the Fisher financial advisors’ financial analyses. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before May 5, 2006 and is not necessarily indicative of current market conditions.
  Contribution Analysis
      The Fisher financial advisors reviewed specific estimated future operating and financial contributions of each of Fisher and Thermo including sales, earnings before interest, taxes and depreciation and amortization, which is referred to as EBITDA, earnings before interest, taxes and amortization, which is referred to as EBITA, GAAP net income and cash net income based on the financial forecasts for 2006 and 2007, before taking into account any of the synergies that may be realized following the merger. The proportionate contributions were calculated taking into account Fisher’s and Thermo’s respective debt and cash and were compared to the estimated ownership by the Fisher stockholders prior to the merger of 61.4% of the outstanding common equity of the combined company following the merger. The following table presents the results of this analysis:
      Fisher Forecast Contribution to Combined Company

  Pro Forma Merger Analysis
      For the year 2007, the Fisher financial advisors compared the earnings per share of the Thermo common stock, projected by Thermo management, as reviewed and approved by Fisher management, on a standalone basis, to the pro forma earnings per share of the combined company following the merger, utilizing forecasts for Fisher prepared by Fisher management and forecasts for Thermo prepared by Thermo management, as reviewed and approved by Fisher management. Based on such analyses, the proposed transaction would be approximately 18% accretive in 2007 on a pro forma cash earnings per share basis.
  Discounted Cash Flow Analysis
      The Fisher financial advisors performed discounted cash flow analyses on Fisher and the combined company using the financial forecasts and, in the case of the combined company, the synergistic savings and benefits projected by Fisher and Thermo to be realized following the merger. For estimates for 2008 through 2010 the Fisher financial advisors utilized, based upon management assumptions, revenue growth equal to the expected market growth rate and EBITDA margins constant at 2007 levels.
      The Fisher financial advisors calculated implied net present values of free cash flows for Fisher, Thermo and the combined company following the merger for the years 2006 through 2010 using discount rates ranging from 8.5% to 10.5%. The Fisher financial advisors calculated implied per share ranges of Fisher common stock, Thermo common stock and the common stock of the combined company to be received by Fisher stockholders in the merger using implied terminal value indications in the year 2010 based on multiples ranging from 10.0 to 13.0 times EBITDA for Fisher, from 11.0 to 14.0 times EBITDA for Thermo and from 11.0 to 14.0 times EBITDA for the combined company. These implied terminal value indications were then discounted to an implied present value using discount rates ranging from 8.5% to 10.5%. These analyses resulted in implied per share values ranging from $76.21 to $102.25 for Fisher, $34.90 to $45.63 for Thermo and $84.60 to $113.65 for the combined company.

Implied Premium Analysis
      The Fisher financial advisors calculated the implied premium for Fisher common stock represented by the 2.0 exchange ratio pursuant to the merger based on the closing prices of Fisher common stock and Thermo common stock during the one-month, three-month, six-month, one-year and two-year periods ended May 5, 2006 and on the closing share prices of Fisher common stock and Thermo common stock on May 5, 2006. The results of this analysis are shown in the following table:

Illustrative Future Trading Value Analysis
      The Fisher financial advisors calculated illustrative implied per share price ranges of the two shares of the combined company to be received for each share of Fisher common stock in the merger, a range of potential synergies from $75 million to $200 million, which represents the synergies estimated by the managements of Thermo and Fisher to be realized in calendar year 2007 and the total synergies to be realized in connection with the proposed transaction, respectively, and the resulting pro forma 2007 cash earnings per share estimates, and an illustrative range of pro forma 2007 estimated price/earnings multiples. Based on a price/earnings multiple range of 16.5 to 19.0 times, the analysis resulted in implied value indications for each share of Fisher common stock ranging from $77.61 to $97.07. This analysis also calculated the pro forma weighted average implied price/earnings multiple of 16.9 times 2007 estimated cash earnings per share based upon the weighted average of Fisher and Thermo managements’ 2007 cash net income forecasts.

      Although none of the selected transactions or the companies party to the transactions is directly comparable to the merger or to Fisher or Thermo, the transactions were chosen because they involve transactions that, for purposes of analysis, may be considered similar to the merger and/or involve publicly traded companies with operations that, for purposes of analysis, may be considered similar to certain operations of Fisher and Thermo.
      For each of the selected transactions, the Fisher financial advisors calculated and, to the extent information was publicly available, compared transaction value as a multiple of each of earnings before interest and taxes, which is referred to as EBIT, EBITDA and sales, in each case, for the latest 12 months, which is referred to as LTM, prior to the date that the merger was announced.

      Based on the closing price of Thermo common stock and Fisher common stock on May 5, 2006, and the exchange ratio of 2.0, the Fisher financial advisors calculated an implied price per share of $78.90 for each share of Fisher common stock. In addition, the Fisher financial advisors calculated an implied enterprise value of approximately $12.8 billion for Fisher using the implied price per share of $78.90, the net debt of Fisher (estimated by Fisher to exist as of March 31, 2006) and the fully diluted number of shares outstanding (assuming treasury method treatment for all of Fisher’s convertible bonds). The Fisher financial advisors also calculated the implied enterprise value as a multiple of each of revenue, EBITDA, and EBIT, for calendar years 2005 and 2006 based on the financial forecasts for Fisher.

Miscellaneous
      The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying the opinions of the Fisher financial advisors. In arriving at their respective opinions, each of the Fisher financial advisors considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, each Fisher financial advisor made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above analyses as a comparison is directly comparable to Fisher or Thermo or the merger.
      The Fisher financial advisors prepared these analyses for purposes of providing their respective opinions to the Fisher board of directors as to the fairness from a financial point of view to the holders of the outstanding shares of Fisher common stock of the exchange ratio. These analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of Fisher, Thermo, either of the Fisher financial advisors or any other person assumes responsibility if future results are materially different from those forecast. As described above, the opinions of each Fisher financial advisor to the Fisher board of directors were two of many factors taken into consideration by the Fisher board of directors in making its determination to approve the merger agreement.
      The exchange ratio was determined through arms’-length negotiations between Fisher and Thermo and was approved by the Fisher board of directors. The Fisher financial advisors provided advice to Fisher during these negotiations. The Fisher financial advisors did not, however, recommend any specific amount of consideration to Fisher or its board of directors or that any specific exchange ratio constituted the only appropriate consideration for the merger.
Financial Interests of Directors and Officers in the Merger
      Some of the members of Thermo’s and Fisher’s management, executive officers and the non-employee directors of their boards of directors have interests in the merger that are in addition to, or different from, the interests of Thermo and Fisher stockholders generally, which are described below. The Thermo and Fisher boards of directors were aware of these interests and considered them, among other matters, in approving the merger agreement, the issuance of Thermo common stock to Fisher stockholders, the amendment of the Thermo charter and the other transactions contemplated by the merger agreement.
Financial Interests of Fisher Directors and Officers in the Merger
Employment Agreements
      Fisher’s executive officers are Messrs. Montrone, Meister, Della Penta, Clark and Rea. Fisher has entered into employment agreements with each of its executive officers that, among other things, provide for certain payments and benefits upon a qualifying termination of the executive’s employment, including a qualifying termination of employment following a “change in control”, referred to as a Qualifying Separation. The consummation of the merger would constitute a change in control for purposes of these agreements.
      Set forth below are the payments and benefits that would be applicable on the assumption that a Qualifying Separation occurred as of October 1, 2006. It is anticipated that Messrs. Montrone’s, Meister’s, Della Penta’s, Clark’s and Rea’s employment under their existing employment agreements with Fisher will terminate upon the consummation of the merger. However, certain executive officers of Fisher are expected to continue to be available to provide services to the combined company after the merger on a basis to be determined as part of the integration planning process.

Table of Contents

      Mr. Montrone. Mr. Montrone’s employment agreement provides for payment of certain post-termination and retirement benefits, as described in Fisher’s Proxy Statement filed with the SEC on April 6, 2006, which is incorporated by reference into this document. These benefits are fully vested and unaffected by the merger.
      Mr. Meister. In a Qualifying Separation, Mr. Meister would be entitled to receive a pro-rata portion of his target bonus for the year of termination and, subject to his remaining available to assist in the transition of his duties and responsibilities, a lump sum payment of severance equal to three times the sum of his annual base salary and target bonus. Mr. Meister would also receive three years of continued fringe benefits, personal perquisites and other benefits provided during his employment. For purposes of calculating his supplemental retirement benefits, Mr. Meister would be deemed to have completed three additional years of service and received the cash severance as compensation for services over such three year period. The amount of the cash payments described above would be approximately $6.9 million. Mr. Meister will serve as non-executive Chairman of the board of directors of the combined company.
      Mr. Della Penta. On January 10, 2006, Fisher’s Compensation Committee accepted Mr. Della Penta’s notification of his retirement from employment effective at the end of 2006.
      In a Qualifying Separation, Mr. Della Penta would be entitled to receive a lump sum payment equal to the product of two times his base salary and outplacement services with a cost of up to $50,000. Mr. Della Penta would also receive two years of continued medical coverage. The amount of the cash payments described above would be approximately $1.3 million.
      Mr. Clark. In a Qualifying Separation, Mr. Clark would be entitled to receive a pro-rata portion of his target bonus for the year of termination, a lump sum payment of severance equal to two and one-half times the sum of his annual base salary and target bonus, and a lump sum payment equal to two and one-half times Fisher’s annual contributions to any defined contribution plans for Mr. Clark. Mr. Clark would also receive from Fisher two and one-half years of continued medical, dental, vision, life insurance and accidental death and dismemberment insurance benefits. For purposes of calculating his supplemental retirement benefits, Mr. Clark would be deemed to have completed two and one-half additional years of service and received his annual base salary and annual bonus as compensation for services over such two and one-half year period. To the extent the date of Mr. Clark’s termination of employment is after Fisher’s fiscal year end, but before the determination of a long term incentive plan payout, Mr. Clark would be entitled to receive the target long term incentive award to which he is then entitled based upon the results for the prior fiscal year. In addition, Mr. Clark would also receive a payment equal to the full target of the long term incentive plan award for the year of termination. The amount of the cash payments described above would be approximately $6.5 million.
      Mr. Rea. In a Qualifying Separation, Mr. Rea would be entitled to receive a pro-rata portion of his target bonus for the year of termination, a lump sum payment of severance equal to two and one-half times the sum of his annual base salary and target bonus, and a lump sum payment equal to two and one-half times Fisher’s annual contributions to any defined contribution plans for Mr. Rea. Mr. Rea would also receive two and one-half years of continued medical, dental, vision, life insurance and accidental death and dismemberment insurance benefits. For purposes of calculating his supplemental retirement benefits, Mr. Rea would be deemed to have completed two and one-half additional years of service and received the cash severance as compensation for services over such two and one-half year period. Mr. Rea would also receive a $20,000 cash payment, which he may use for outplacement services. The amount of the cash payments described above would be approximately $1.1 million.
Equity-Based Awards
      As described in “The Merger — Treatment of Stock Options and Other Equity-Based Awards,” upon completion of the merger each outstanding Fisher option, whether or not exercisable, will be assumed by Thermo and converted into an option to acquire the number of shares of Thermo common stock equal to two times the number of shares of Fisher common stock that were subject to the original Fisher stock option at a per share exercise price equal to the exercise price per share of the original Fisher stock option divided by two (rounded up to the nearest whole cent). Each converted Fisher stock option will have the same terms and

43


Table of Contents

conditions as were in effect immediately prior to the merger, subject to any accelerated vesting as a result of the merger to the extent provided by the terms of the applicable Fisher stock plan.
      Upon completion of the merger, each Fisher stock unit award will be assumed by Thermo and converted into a stock unit award in respect of the number of shares of Thermo common stock equal to two times the number of shares of Fisher common stock subject to the Fisher stock unit award. Each converted stock unit award will have the same terms and conditions as were in effect immediately prior to the merger, except that the performance conditions applicable to the vesting of the converted stock unit awards will be deemed to have been satisfied upon completion of the merger, and the converted stock unit awards (other than those stock unit awards granted under the Fisher 2005 Equity and Incentive Plan which are subject to a performance based restricted stock unit purchase agreement, referred to as Investment RSUs, and which become vested and payable in accordance with their current terms upon the merger) will instead generally vest and be settled in three equal increments on the first three anniversaries of their original grant date, subject to the holder’s continued employment on each such vesting date (other than upon a Qualifying Separation, in which case such award would vest immediately upon such Qualifying Separation).
      As soon as practicable following the merger, Fisher will make cash payments as contemplated by the initial terms of grant for the Investment RSUs. Similar cash payments to Fisher’s executive officers as contemplated by the initial terms of grant for other restricted stock unit awards, referred to as Cash Payment RSUs, will vest and become payable in three equal installments on each of the first, second and third anniversaries of their original grant date, subject to the holder’s continued employment on each such payment date (other than upon a Qualifying Separation, in which case such award would vest immediately upon such Qualifying Separation). Assuming that each of Messrs. Montrone, Meister, Della Penta, Clark and Rea experience a Qualifying Separation immediately following completion of the merger, the aggregate amount of all such cash payments (with respect to both Investment RSUs and Cash Payment RSUs) payable to Messrs. Montrone, Meister, Della Penta, Clark and Rea will be approximately $4.1 million, $3.3 million, $0.6 million, $2.2 million and $0.4 million, respectively.
      Pursuant to the initial grant terms for certain stock option and restricted stock unit awards and/or underlying equity incentive plans, the consummation of the merger will result in the vesting of certain stock options and restricted stock units held by Fisher’s executive officers. In addition, certain unvested stock options and restricted stock unit awards will vest and/or become free of restrictions if the holder experiences a Qualifying Separation following the consummation of the merger. Assuming that each of Messrs. Montrone, Meister, Della Penta, Clark and Rea experience a Qualifying Separation immediately following completion of the merger, the aggregate amount and value (based on an assumed Fisher stock price of $73.75) of all such unvested Fisher stock options and the number of Fisher restricted stock units held by the Fisher executive officers that will become fully vested and/or free of restrictions in connection with the completion of the merger and such Qualifying Separation is as follows:
                                 
        Aggregate Spread        
    Number of Shares   for All Unvested   Total Number of   Aggregate Value for

Interests of Directors
      Each of Fisher’s non-employee directors hold options to acquire Fisher common stock, which ordinarily vest over three years from the date of grant, subject to the director’s continued service on the board. Any such options which are unvested will become fully vested at the time of the merger. A total of 160,004 unvested options held by Fisher’s non-employee directors as a group will vest in connection with the merger.

44


Table of Contents

      Each of Fisher’s non-employee directors hold restricted stock units, which ordinarily vest over three years from the date of grant, subject to the director’s continued service on the board. Any such restricted stock units which are unvested will become fully vested at the time of the merger. A total of 16,000 unvested restricted stock units held by Fisher’s non-employee directors as a group will vest in connection with the merger.
      Pursuant to the terms of the Retirement Plan for Non-Employee Directors of Fisher Scientific International Inc., upon a change in control, a non-employee director with less than 5 years of eligible service on the Fisher Board will be deemed to have completed 5 years of eligible service for purposes of receiving benefits under the plan. As a result of the merger, the retirement benefits of six non-employee directors will vest.
Indemnification and Insurance
      The merger agreement provides that, for at least six years after the merger, the combined company will indemnify and hold harmless, and provide advancement of expenses to, all present and former officers and directors of Fisher and its subsidiaries with respect to acts or omissions occurring prior to the merger, including those relating to the merger, to the fullest extent permitted by applicable laws. After the merger, the combined company will also fulfill and honor the obligations of Fisher under any indemnification agreements between Fisher and its present or former directors, officers and employees.
      The merger agreement also provides that the combined company will maintain for a period of six years after completion of the merger the current directors’ and officers’ and fiduciary liability insurance policies maintained by Fisher, or policies of at least the same coverage and amount and containing terms and conditions that are not less advantageous than the current policies, with respect to facts or events occurring prior to the merger, including events relating to the merger, although the combined company will not be required to make aggregate annual premium payments for such policies in excess of 250% of the annual premiums currently paid by Fisher and its subsidiaries for directors’ and officers’ and fiduciary liability insurance. In the event that the combined company is unable to maintain or obtain such insurance, the combined company will obtain as much comparable insurance as is available for annual premium payments equal to 250% of the annual premiums currently paid by Fisher for directors’ and officers’ and fiduciary liability insurance.
Surviving Company Board of Directors
      For a discussion of the composition of the surviving company board of directors, see “— Board of Directors and Management Following the Merger.”
Financial Interests of Thermo Directors and Officers in the Merger
      Existing Thermo Change in Control Retention Agreements. The seven executive officers of Thermo, including Marijn E. Dekkers, Marc N. Casper, Guy Broadbent, Seth H. Hoogasian and Peter M. Wilver, have previously entered into agreements with Thermo that contain change in control severance provisions. Under these agreements, if, during the eighteen-month period following a change in control of Thermo, the employment of a covered executive is terminated other than for “cause” or disability, or by the covered executive for “good reason,” the covered executive will be entitled to receive the following payments and benefits: (1) a pro-rata annual bonus through the date of termination, based on the annual bonus paid for the most recently completed year, (2) a payment equal to two (three in the case of Mr. Dekkers) times the sum of the executive’s highest annual base salary during the five-year period preceding the change in control and the executive’s highest annual bonus earned during the same five-year period, (3) two years (three in the case of Mr. Dekkers) of benefits continuation and (4) outplacement services. If any amounts or benefits received under the change in control retention agreements or otherwise are subject to the excise tax imposed under section 4999 of the Internal Revenue Code, an additional payment will be made to restore the executive to the after-tax position that he would have been in if the excise tax had not been imposed. The merger will be a change in control for purposes of these agreements. Assuming the merger is completed after September 30, 2006, it is currently estimated that the aggregate amount of the cash severance payments that could become

payable to the seven executive officers of Thermo, as a group, upon their qualifying terminations of employment following the completion of the merger, is $19,370,000 in the aggregate.
      Thermo Deferred Compensation Plans. Thermo maintains two deferred compensation plans, one for certain employees and one for non-employee directors. In the event of a change in control of Thermo, the employee deferred compensation plan requires the appointment of a third-party administrator and provides that if the plan is terminated all account balances must be paid as lump sum distributions. The merger will be a change in control for purposes of this plan, although Thermo intends to amend the plan to provide that the merger will not constitute a change in control under the plan. In the event of a change in control of Thermo, the director deferred compensation plan provides that the plan will terminate and all account balances denominated in Thermo stock units will be distributed in shares of Thermo common stock. The merger will be a change in control for purposes of the director plan. Based on the expected account balances of the four active participating non-employee directors as of September 30, 2006, the approximate number of shares of Thermo common stock to be distributed to them as a group is 74,672 in the aggregate.
      Thermo Equity-Based Awards. Pursuant to the terms of the Thermo equity incentive plans, upon a change in control of Thermo, substantially all of the outstanding awards under the plans will vest, become exercisable or be settled and/or the restrictions thereon will lapse, as applicable. In connection with the execution of the merger agreement, Mr. Dekkers waived his right to accelerated vesting of his currently outstanding options to acquire 1,264,600 shares of Thermo common stock solely as a result of the merger.
      Assuming the merger is completed after September 30, 2006, (1) the number of unvested stock options to acquire shares of Thermo common stock held by six of the Thermo executive officers as a group that will become fully vested upon completion of the merger is 1,444,662, in the aggregate, (2) the number of shares of restricted Thermo common stock and restricted stock units held by the seven Thermo executive officers as a group that will vest and become free of restriction in connection with the completion of the merger is 145,001, in the aggregate, and (3) the number of unvested stock options to acquire shares of Thermo common stock held by the seven non-employee directors of Thermo as a group that will become fully vested upon completion of the merger is 190,326, in the aggregate.
      Future Long-Term Incentive Awards. Pursuant to the merger agreement, the board of directors of Thermo will, in consultation with Fisher, establish a long-term incentive compensation program for the benefit of the senior management of the combined company. Subject to completion of the merger, this program will provide each such individual with unvested long-term incentive compensation that is comparable in aggregate value to the currently unvested (but which will vest upon the completion of the merger as described above) equity-based awards that are now held by such individuals.
Board of Directors and Management Following the Merger
      Following the merger, the board of directors of the combined company will consist of eight directors and for a period of three years will be maintained at a ratio of five directors selected by Thermo and three directors selected by Fisher. If there is a vacancy created by the cessation of service by a Thermo director, a majority of the remaining Thermo directors will propose a nominee to fill the vacant position. Similarly, if there is a vacancy created by the cessation of service by a Fisher director, a majority of the remaining Fisher directors will propose a nominee to fill the vacant position. Following the merger, Mr. Dekkers will serve as President and Chief Executive Officer and Mr. Meister will serve as non-executive Chairman of the board of directors, of the combined company and in that role will continue to advise the combined company on strategic matters.

Material U.S. Federal Income Tax Consequences of the Merger
      The following is a discussion of the material U.S. federal income tax consequences of the merger to Fisher stockholders who exchange their shares of Fisher common stock for shares of Thermo common stock in the merger. This discussion addresses only Fisher stockholders who are U.S. Holders (as defined below) and hold Fisher common stock as a capital asset. It does not address all of the U.S. federal income tax consequences that may be relevant to a particular Fisher stockholder in light of that stockholder’s individual circumstances or to a Fisher stockholder who is subject to special rules, including, without limitation:
  •  a financial institution or insurance company;
 
  •  a tax-exempt organization;
 
  •  a stockholder who is not a U.S. Holder;
 
  •  a pass-through entity or an investor in such an entity;
 
  •  a dealer or broker in securities or foreign currencies;
 
  •  a trader in securities who elects to apply a mark-to-market method of accounting;
 
  •  a stockholder who holds Fisher common stock as part of a hedge, appreciated financial position, straddle, constructive sale or conversion transaction; and
 
  •  a stockholder who acquired his or her shares of Fisher common stock pursuant to the exercise of employee stock options or otherwise as compensation.
      The following discussion is based on the Code, applicable Treasury regulations, administrative interpretations and court decisions, each as in effect as of the date of this document and all of which are subject to change, possibly with retroactive effect. This discussion is not binding on the Internal Revenue Service, which is referred to as the IRS, and there can be no assurance that the IRS (or a court, if challenged by the IRS) will agree with the conclusions stated herein. In addition, this discussion does not address any state, local or foreign tax consequences of the merger. Fisher stockholders are urged to consult their tax advisors as to the specific tax consequences to them of the merger in light of their particular circumstances including the applicability and effect of U.S. federal, state, local, foreign income and other tax laws.
      For purposes of this discussion, “U.S. Holder” refers to a beneficial holder of Fisher common stock that is, for U.S. federal income tax purposes, (i) an individual citizen or resident of the United States, (ii) a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (iv) a trust (x) that is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (y) that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.
      If an entity treated as a partnership for U.S. federal income tax purposes holds Fisher common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of that partnership. If a U.S. Holder is a partner of a partnership holding that common stock, the holder should consult its tax advisor regarding the tax consequences of the merger.
      It is a condition to the completion of the merger that Thermo receive a written opinion from its counsel, Wachtell, Lipton, Rosen & Katz, and that Fisher receive a written opinion from its counsel, Skadden, Arps,

Table of Contents

Slate, Meagher & Flom LLP, in each case dated as of the effective date of the merger, to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. Neither Thermo nor Fisher intends to waive this closing condition. In the event that either Thermo or Fisher waives receipt of such opinion from its counsel, however, Thermo and Fisher will resolicit the approval of its stockholders after providing appropriate disclosure. The opinions will rely on certain assumptions as well as representations made by Thermo, Trumpet Merger Corporation and Fisher. If any of those assumptions or representations are inaccurate, counsel may not be able to render the required opinions and the tax consequences of the merger could differ from those discussed here. An opinion of counsel is not binding on the IRS or any court, nor does it preclude the IRS from adopting a contrary position. No ruling has been or will be sought from the IRS on the U.S. federal income tax consequences of the merger.
      Assuming that the merger qualifies as a reorganization within the meaning of Section 368(a) of the Code, for U.S. federal income tax purposes:
  •  a Fisher stockholder whose shares of Fisher common stock are exchanged in the merger for shares of Thermo common stock will not recognize gain or loss;
 
  •  a Fisher stockholder’s aggregate tax basis in shares of Thermo common stock received in the merger will equal the aggregate tax basis of the Fisher common stock surrendered in the merger; and
 
  •  a Fisher stockholder’s holding period for shares of Thermo common stock received in the merger will include the holding period for the shares of Fisher common stock surrendered in the merger.
Information Reporting
      U.S. Holders receiving Thermo common stock as a result of the merger generally will be required to retain records pertaining to the merger and generally will be required to file with their U.S. federal income tax return for the year in which the merger takes place a statement setting forth certain facts relating to the merger.
Accounting Treatment
      Thermo prepares its financial statements in accordance with GAAP. The merger will be accounted for using the purchase method of accounting. Statement of Financial Accounting Standards No. 141, Business Combinations, referred to as SFAS 141, provides guidance for determining the accounting acquirer in a business combination when equity interests are exchanged between two entities. SFAS 141 provides that in a business combination effected through an exchange of equity interests, such as the merger, the entity that issues the equity interests is generally the acquiring entity. In some business combinations, however, the acquired entity issues the equity interests. Commonly, the acquiring entity is the larger entity. However, the facts and circumstances surrounding a business combination sometimes indicate that a smaller entity acquires a larger one. SFAS 141 further provides that in identifying the acquiring entity in a combination effected through an exchange of equity interests, all pertinent facts and circumstances must be considered, including: the relative voting rights of the stockholders of the constituent companies in the combined entity, the composition of the board of directors and senior management of the combined company and the terms of the exchange of equity securities in the business combination, including payment of any premium.
      Based on the Thermo board members and senior management representing a majority of the board and senior management of the combined company, as well as the terms of the exchange, with Fisher shareholders receiving a premium (as of the date preceding the merger announcement) over the fair market value of their shares on such date, Thermo is considered to be the acquirer of Fisher for accounting purposes. This means that Thermo will allocate the purchase price to the fair value of Fisher’s assets and liabilities at the acquisition date, with the excess purchase price being recorded as goodwill. Under the purchase method of accounting, goodwill is not amortized but is tested for impairment annually.
Regulatory Approvals Required for the Merger
      Thermo and Fisher have each agreed to use reasonable best efforts in order to obtain all regulatory approvals required in order to consummate the merger.

Table of Contents

      Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and related rules (referred to as the HSR Act), the merger cannot be completed until the expiration of a waiting period that follows the filing of notification forms by both parties to the transaction with the U.S. Federal Trade Commission (referred to as the FTC) and the Antitrust Division of the U.S. Department of Justice (referred to as the Antitrust Division). Thermo and Fisher are in the process of finalizing submission of the necessary notification and report forms under the HSR Act with the FTC and the Antitrust Division, which the parties expect to complete on or before July 26, 2006. The initial waiting period is 30 days after the filing of the notification and report forms, but this period may be extended if the reviewing agency issues a formal request for additional information and documentary material, referred to as a second request. If the reviewing agency issues a second request, the parties may not complete the merger until 30 days after both parties substantially comply with the second request, unless the waiting period is terminated earlier.
      At any time before or after completion of the merger, the Antitrust Division or the FTC or any state could take such action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger, to rescind the merger or to seek divestiture of particular assets of Thermo or Fisher. Private parties also may seek to take legal action under the antitrust laws under certain circumstances. As in every transaction, a challenge to the merger on antitrust grounds may be made, and, if such a challenge is made, it is possible that Thermo and Fisher will not prevail.
      Thermo and Fisher each conducts business in member states of the European Union. Council Regulation (EEC) 139/2004, as amended, requires notification to and approval by the European Commission of mergers or acquisitions involving parties with aggregate worldwide sales and individual European Union sales exceeding specific thresholds before these mergers or acquisitions are implemented. Thermo and Fisher intend to file a merger notification with the European Union antitrust authorities as soon as practicable.
      The European Commission must review the merger to determine whether or not it is compatible with the common market, and, accordingly, whether or not to permit it to proceed. A merger or acquisition that would not significantly impede effective competition in the common market or in a substantial part of it, in particular as a result of the creation or strengthening of a dominant position, shall be declared compatible with the common market and must be allowed to proceed. If, following a preliminary 25 business days Phase I investigation, which may be extended to 35 business days, the European Commission determines that it needs to examine the merger more closely because the merger raises serious doubts as to its compatibility with the common market, it must initiate a Phase II investigation. If it initiates a Phase II investigation, the European Commission must issue a final decision as to whether or not the merger is compatible with the common market no later than 125 business days after the initiation of the Phase II investigation.
      Thermo and Fisher conduct operations in a number of jurisdictions where other regulatory filings or approvals may be required or advisable in connection with the completion of the merger. Thermo and Fisher are currently reviewing whether filings or approvals may be required or advisable in those jurisdictions that may be material to Thermo and Fisher. It is possible that any of the regulatory authorities with which filings are made may seek regulatory concessions as conditions for granting approval of the merger.
      Prior to completing the merger, the applicable waiting period under the HSR Act must expire or be terminated, and Thermo and Fisher are required to obtain the requisite antitrust approvals from the European Commission. In addition, Thermo and Fisher must obtain requisite approvals from any other regulatory authorities if the failure to obtain approvals of those regulatory authorities would have a material adverse effect on Thermo and its subsidiaries taken as a whole, or Fisher and its subsidiaries taken as a whole, respectively, in each case after giving effect to the merger.
      Although we do not expect regulatory authorities to raise any significant objections in connection with their review of the merger, we cannot assure you that we will obtain all required regulatory approvals or that these regulatory approvals will not contain terms, conditions or restrictions that would be detrimental to the combined company after the completion of the merger.

Exchange of Certificates in the Merger
      At or prior to the effective time of the merger, an exchange agent will be appointed to handle the exchange of Fisher stock certificates for certificates representing shares of Thermo common stock. Promptly after the effective time of the merger, the exchange agent will send a letter of transmittal and instructions to each former Fisher stockholder explaining the procedure for surrendering Fisher stock certificates in exchange for certificates representing the number of shares of Thermo common stock into which the shares of Fisher common stock will be converted in the merger.
      After the effective time of the merger, each certificate that previously represented shares of Fisher common stock will represent only the right to receive a certificate representing the shares of Thermo common stock into which the shares of Fisher common stock have been converted. In addition, after the effective time of the merger, Fisher will not register any transfers of the shares of Fisher common stock. Thermo stockholders need not exchange their stock certificates.
Treatment of Stock Options and Other Equity-Based Awards
      Upon completion of the merger, each outstanding option to acquire Fisher common stock, whether or not exercisable, will be assumed by Thermo and converted into an option to acquire that number of whole shares of Thermo common stock equal to the product of the number of shares of Fisher common stock that were subject to the original Fisher stock option multiplied by the exchange ratio (rounded down to the nearest whole share) at a per share exercise price equal to the exercise price per share of the original Fisher stock option divided by the exchange ratio (rounded up to the nearest whole cent). Each converted Fisher stock option will have the same terms and conditions as were in effect immediately prior to the completion of the merger, subject to any accelerated vesting as a result of the merger to the extent provided by the terms of the applicable Fisher stock plan.
      Upon completion of the merger, each stock unit award in respect of Fisher common stock will be assumed by Thermo and converted into a stock unit award in respect of the number of shares of Thermo common stock (or an amount in respect thereof for cash settled Fisher stock unit awards) equal to the number of shares of Fisher common stock subject to the Fisher stock unit award, multiplied by the exchange ratio (rounded down to the nearest whole share). Each converted stock unit award will have the same terms and conditions as were in effect immediately prior to the completion of the merger, except that the performance conditions applicable to the vesting of the converted stock unit awards will be deemed to have been satisfied upon completion of the merger, and the converted stock unit awards (other than those stock unit awards granted under the Fisher 2005 Equity and Incentive Plan that are evidenced by a performance based restricted stock unit investment agreement and which become vested and payable in accordance with their current terms upon a change in control transaction, such as the completion of the merger) will instead generally vest and be settled in three equal increments on the first three anniversaries of their original grant date, subject to the holder’s continued employment with the combined company or the surviving corporation as of each such vesting date.
      Prior to the completion of the merger, Thermo will take the corporate action necessary to reserve for issuance a sufficient number of shares of Thermo common stock for delivery in connection with the exercise of the converted stock options and stock unit awards and, within one business day of the completion of the merger, Thermo will register the shares of Thermo common stock subject to such converted options and awards.
      Following the completion of the merger, Thermo may grant equity awards under the Fisher stock and equity incentive plans, to the extent shares are available for grant under any such plan, in accordance with the mergers and acquisitions exemption to the equity compensation plan shareholder approval requirement under the NYSE rules.

Restrictions on Sales of Shares of Thermo Common Stock Received in the Merger
      Thermo common stock issued in the merger will not be subject to any restrictions on transfer arising under the Securities Act, except for shares issued to any Fisher stockholder who may be deemed to be an “affiliate” of Thermo or Fisher for purposes of Rule 145 under the Securities Act.
      Under Rule 145, former Fisher stockholders who were affiliates of Fisher at the time of the Fisher special meeting and who are not affiliates of Thermo after the completion of the merger, may sell their Thermo common stock received in the merger at any time subject to the volume and sale limitations of Rule 144 under the Securities Act. Further, so long as such former Fisher affiliates are not considered affiliates of Thermo following the completion of the merger, and a period of at least one year has elapsed from the completion of the merger, such former affiliates may sell their Thermo common stock received in the merger without regard to the volume and sale limitations of Rule 144 under the Securities Act so long as there is adequate current public information available about Thermo in accordance with Rule 144. After a period of two years has elapsed from the completion of the merger, and so long as such former affiliates are not affiliates of Thermo and have not been for at least three months prior to such sale, such former affiliates may freely sell their Thermo common stock. Former Fisher stockholders who become affiliates of Thermo after completion of the merger will still be subject to the volume and sale limitations of Rule 144 under the Securities Act, until each such stockholder is no longer an affiliate of Thermo. This document does not cover resales of Thermo common stock received by any person upon completion of the merger, and no person is authorized to make any use of this document in connection with any resale.
Listing of Thermo Common Stock
      It is a condition to the completion of the merger that the Thermo common stock issuable in the merger or upon exercise of options to purchase Thermo common stock issued in substitution for Fisher options be approved for listing on the NYSE, subject to official notice of issuance.
Appraisal Rights
      Under the General Corporation Law of the State of Delaware, or the DGCL, holders of Fisher common stock are not entitled to appraisal rights in connection with the merger. See the section entitled “Appraisal Rights” beginning on page 88.

The rights and obligations of the parties are governed by the express terms and conditions of the merger agreement and not by this summary or any other information contained in this document.

Table of Contents

  •  the receipt of an opinion of that party’s counsel to the effect that the merger will qualify as a “reorganization” under the Code.
Reasonable Best Efforts to Obtain Required Stockholder Votes
      Each company has agreed to take all lawful action to give notice of, convene and hold a meeting of its stockholders as promptly as practicable for the purpose of obtaining the required stockholder vote to approve the transactions contemplated by the merger agreement. In addition, each party has agreed to use its reasonable best efforts to obtain from its stockholders the required stockholder vote, in the case of Thermo, in favor of the stock issuance proposal and the Thermo charter amendment proposal, and in the case of Fisher, in favor of adoption of the merger agreement.
No Solicitation
      Each company has agreed that from the time of the execution of the merger until the consummation of the merger or the termination of the merger agreement, subject to certain customary exceptions, none of Fisher or Thermo, their respective subsidiaries or any officer, director, employee, agent or representative (including any investment banker, financial advisor, attorney, accountant or other retained representative) of Fisher or Thermo will directly or indirectly solicit, initiate or encourage or knowingly facilitate (including by way of furnishing information or entering into any agreements, arrangements or understandings) or take any other action designed to facilitate any inquiries or proposals regarding any merger, share exchange, consolidation, sale of assets, sale of shares of capital stock (including, without limitation, by way of a tender offer) or similar transactions involving Fisher or Thermo or any of their respective subsidiaries. Additionally, each company has agreed that neither company will participate in any discussions or negotiations regarding any alternative transaction to this transaction or enter into any agreement regarding any alternative transaction.
      Nevertheless, the board of directors of both Fisher and Thermo will be permitted to, prior to the receipt of the relevant stockholder approval required to consummate the merger, furnish information with respect to Fisher or Thermo and their respective subsidiaries, to a person making a bona fide written alternative transaction proposal and participate in discussions and negotiations with respect to such bona fide written alternative transaction proposal received by Fisher or Thermo, if the board of directors of such company determines in good faith (after consultation with outside legal counsel) that the failure to do so would, or would reasonably be likely to, cause it to violate its fiduciary duties. The merger agreement requires that the companies notify each other if any alternative transaction proposals are presented to either company.
      The merger agreement requires both Fisher and its subsidiaries, and Thermo and its subsidiaries, to cease and terminate any existing discussions or negotiations with any persons conducted prior to the execution of the merger agreement and use reasonable best efforts to cause all persons other than Fisher or Thermo who have been furnished confidential information regarding Fisher or Thermo in connection with the solicitation of or discussions regarding an alternative transaction proposal within the 12 months prior to the date of the signing of the merger agreement to promptly return or destroy such information. In addition, Fisher and Thermo agree not to, and to cause their respective subsidiaries not to, release any third party from the confidentiality and standstill provisions of any agreement to which Fisher or Thermo or their respective subsidiaries is or may become a party.
      Fisher and Thermo are required to use their reasonable best efforts to inform their respective representatives of the no solicitation restrictions provided for in the merger agreement.
Termination of the Merger Agreement
      Right to Terminate. The merger agreement may be terminated at any time prior to the effective time of the merger, under the following circumstances:
  •  by mutual written consent of Fisher and Thermo, if the board of directors of each so determines;

  •  by written notice of either Fisher or Thermo (as authorized by the board of directors of Fisher or Thermo, as applicable):
  1.  if the merger is not consummated by May 7, 2007;
 
  2.  if a governmental entity issues a final and nonappealable order, decree or ruling or takes any other action that permanently restrains, enjoins or otherwise prohibits the merger;
 
  3.  if Fisher’s stockholder approval is not obtained at Fisher’s stockholder meeting or at any adjournment or postponement, at which the vote to obtain the approval required for this transaction is taken; or

  •  by Fisher upon a breach of any representation, warranty, covenant or agreement on the part of Thermo, or if any representation or warranty of Thermo becomes untrue, in either case such that the conditions to Fisher’s obligations to complete the merger would not then be satisfied and in any such case such breach is incapable of being cured or is not cured in all material respects within 10 days after written notice of such breach is received by Thermo;
 
  •  by Thermo upon a breach of any representation, warranty, covenant or agreement on the part of Fisher, or if any representation or warranty of Fisher becomes untrue, in either case such that the conditions to Thermo’s obligations to complete the merger would not then be satisfied and in any such case such breach is incapable of being cured or is not cured in all material respects within 10 days after written notice of such breach is received by Fisher;
 
  •  by Fisher if the board of directors of Thermo, for any reason fails to recommend in this document a vote in favor of the stock issuance and the charter amendment, or in a manner adverse to Fisher withdraws, modifies or qualifies, or proposes to withdraw, modify or qualify, the recommendation by the board of directors in favor of the stock issuance and the charter amendment to Thermo’s stockholders.

Additionally, Thermo can terminate if Fisher takes any public action or makes any public statement in connection with the meeting of Fisher stockholders inconsistent with the recommendation to approve the adoption of the merger agreement or recommends any alternative transaction.
Termination Fee
      If the merger agreement is validly terminated, the agreement will become void without any liability on the part of any party unless the party is in willful or intentional breach of any representation, warranty, covenant or agreement contained in the merger agreement. The provisions of the merger agreement relating to the effects of termination, fees and expenses, termination payments, governing law, jurisdiction, waiver of jury trial and specific performance, as well as the confidentiality agreement entered into between Thermo and Fisher, will continue in effect notwithstanding termination of the merger agreement. Upon a termination, a

In general, each of Thermo and Fisher has agreed to (1) maintain its existence in good standing under applicable laws, (2) conduct its operations only in the ordinary and usual course of business consistent with past practice and (3) use its reasonable best efforts to keep available the services of the current officers, key employees and key consultants of each of our companies, and to preserve the current relationships of each company, with its customers, suppliers and other persons with which it has significant business relations as are reasonably necessary in order to preserve substantially intact its business organization.
      In addition, between the date of the merger agreement and the effective time of the merger, each of Fisher and Thermo, has agreed to various specific restrictions relating to the conduct of its business, including the following (subject in each case to exceptions specified in the merger agreement or previously disclosed in writing as provided in the merger agreement):

      The representations described above and included in the merger agreement were made for purposes of the merger agreement and are subject to qualifications and limitations agreed by the respective parties in connection with negotiating the terms of the merger agreement. In addition, certain representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. This description of the representations and warranties, and their reproduction in the copy of the merger agreement attached to this document as Annex A, are included solely to provide investors with information regarding the terms of the merger agreement. Accordingly, the representations and warranties and other provisions of the merger agreement should not be read alone, but instead should be read together with the information provided elsewhere in this document and in the documents incorporated by reference into this document. See “Where You Can Find More Information” on page 89.
Employee Benefits Matters
      Thermo has agreed to provide non-union Fisher employees, for a period of two years following closing, with benefits (other than options or equity-based awards or incentive plans) in the aggregate substantially no less favorable than benefits under comparable Fisher plans. Thermo will give Fisher employees full credit for purposes of eligibility, vesting, determination of level of benefits and benefit accrual under any employee benefit plans or arrangements maintained by Thermo.
      In connection with the merger, Thermo will waive all limitations on preexisting conditions or waiting periods with respect to participation and coverage requirements applicable to the Fisher employees under any welfare benefit plans that the employees may be eligible to participate. Thermo has also agreed to provide each Fisher employee with credit for any co-payments and deductibles paid under any Fisher benefit plan that provides healthcare benefits in the plan year in effect as of the closing in satisfying any applicable deductible or out-of-pocket expenses under any healthcare plans of Thermo.
      For any employee whose terms and conditions of employment are governed by collective bargaining agreements, Thermo will honor each of Fisher’s existing collective bargaining agreements and the terms and conditions thereunder.
Combined Company Headquarters and Fisher Offices
      The parties agreed that the headquarters of the combined company will be located in Waltham, Massachusetts, Thermo’s current headquarters, and that the combined company will maintain the current offices of Fisher in its current facility in Hampton, New Hampshire for at least three years after the completion of the merger.
Amendments, Extensions and Waivers
      Amendment. The merger agreement may be amended by the parties at any time before or after the Fisher stockholders or the Thermo stockholders approve the merger, the issuance of Thermo common stock in the merger or the Thermo charter amendments. However, after any such stockholder approval, there may not be, without further approval of Thermo stockholders and Fisher stockholders, any amendment of the merger agreement that changes the amount or the form of the consideration to be delivered to Fisher stockholders, or any amendment for which applicable laws expressly require further stockholder approval.

UNAUDITED PRO FORMA CONDENSED
COMBINED FINANCIAL STATEMENTS
      The unaudited pro forma condensed combined balance sheet as of April 1, 2006, and the unaudited pro forma condensed combined statements of income for the three months ended April 1, 2006 and the year ended December 31, 2005, are presented herein. The unaudited pro forma condensed combined balance sheet combines the unaudited condensed balance sheets of Thermo and Fisher and gives effect to the merger as if it had been completed on April 1, 2006. The unaudited pro forma condensed combined statements of income for the three months ended April 1, 2006 and the year ended December 31, 2005 combine the historical results of Thermo and Fisher and give effect to the merger as if it had occurred on January 1, 2005. The unaudited pro forma condensed combined statement of income for the year ended December 31, 2005 also gives effect to Thermo’s May 2005 acquisition of the Kendro Laboratory Products business as if it had occurred on January 1, 2005.
      The unaudited pro forma condensed combined financial statements presented are based on the assumptions and adjustments described in the accompanying notes. The unaudited pro forma condensed combined financial statements are presented for illustrative purposes and do not purport to represent what the financial position or results of operations would actually have been if the merger occurred as of the dates indicated or what such financial position or results would be for any future periods. The unaudited pro forma condensed combined financial statements are based upon the respective historical consolidated financial statements of Thermo and Fisher, and should be read in conjunction with:
  •  the accompanying notes to the unaudited pro forma condensed combined financial statements;
 
  •  the separate historical financial statements of Thermo as of and for the three months ended April 1, 2006 included in Thermo’s quarterly report on Form 10-Q for the three months ended April 1, 2006, which is incorporated by reference into this document;
 
  •  the separate historical financial statements of Thermo as of and for the year ended December 31, 2005 included in Thermo’s annual report on Form 10-K for the year ended December 31, 2005, which is incorporated by reference into this document;
 
  •  the separate historical financial statements of Fisher as of and for the three months ended March 31, 2006 included in Fisher’s quarterly report on Form 10-Q for the three months ended March 31, 2006, which is incorporated by reference into this document; and
 
  •  the separate historical financial statements of Fisher as of and for the year ended December 31, 2005 included in Fisher’s current report on Form 8-K filed May 11, 2006, to reflect the account balances and activities of the laboratory workstations business as discontinued operations, which is incorporated by reference into this document.
      The unaudited pro forma condensed combined financial information was prepared using the purchase method of accounting. As discussed under “Accounting Treatment” on page 48, based upon the terms of the merger and other factors, such as the composition of the combined company’s board and senior management, Thermo is treated as the acquirer of Fisher. Accordingly, we have adjusted the historical combined financial information to give effect to the impact of the consideration issued in connection with the merger. In the unaudited pro forma condensed consolidated balance sheet, Thermo’s cost to acquire Fisher has been allocated to the assets acquired and liabilities assumed based upon management’s preliminary estimate of their respective fair values as of the date of the merger. Any differences between fair value of the consideration issued and the fair value of the assets and liabilities acquired will be recorded as goodwill. The amounts allocated to acquired assets and liabilities in the unaudited pro forma condensed combined financial statements are based on management’s preliminary internal valuation estimates. Definitive allocations will be performed and finalized based on certain valuations and other studies that will be performed by Thermo with the services of outside valuation specialists after the closing of the merger. Accordingly, the purchase price allocation adjustments and related amortization reflected in the following unaudited pro forma condensed combined financial statements are preliminary, have been made solely for the purpose of preparing these statements and are subject to revision based on a final determination of fair value after the closing of the

62


Table of Contents

merger. For example, if the value of the definite-lived intangible assets increased by 10%, annual pro forma income from continuing operations would decrease by $41 million.
      The unaudited pro forma condensed combined statements of income also include certain purchase accounting adjustments, including items expected to have a continuing impact on the combined results, such as increased amortization expense on acquired intangible assets.
      In analysis contained elsewhere in this document, Thermo’s investment banker, Lehman Brothers, reviewed prospective financial data for the combined entity on both a reported (GAAP) and adjusted basis. Adjusted results are not prepared in accordance with generally accepted accounting principles. For future periods, the chief difference between GAAP and adjusted results assumed by Lehman is the inclusion of amortization expense from acquisition-related intangible assets in GAAP results and the exclusion of this expense from adjusted results. The following historic pro forma results are presented on a GAAP basis only. After-tax amortization expense totaled $0.29 and $1.13 per share in the pro forma combined statement of operations for the first quarter of 2006 and the year ended December 31, 2005, respectively.
      The unaudited pro forma condensed combined statements of income do not include the impacts of any revenue, cost or other operating synergies that may result from the merger or any related restructuring costs. Cost savings, if achieved, could result from material sourcing and elimination of redundant costs including headcount and facilities.
      The unaudited pro forma condensed combined financial statements do not reflect the impact of financing, liquidity or other balance sheet repositioning that may be undertaken in connection with or subsequent to the merger. For example, Thermo’s board of directors authorization of the repurchase of up to $300 million of Thermo common stock through May 7, 2007 is not reflected herein.
      The unaudited pro forma condensed combined financial statements do not reflect certain amounts resulting from the merger because we consider them to be of a non-recurring nature. Such amounts will be comprised of charges for the sale of inventories revalued at the date of acquisition as well as restructuring and other exit and non-recurring costs related to the integration of the Thermo and Fisher businesses. To the extent the exit costs relate to the Fisher business and meet certain criteria, they will be recognized in the opening balance sheet in accordance with EITF Issue No 95-3, “Recognition of Liabilities in Connection with a Purchase Business Combination.” To the extent that such costs relate to Thermo businesses, they will not meet the criteria in EITF Issue No 95-3, and will be recorded as expenses pursuant to SFAS No. 146. Thermo and Fisher have just recently begun collecting information in order to formulate detailed integration plans to deliver planned synergies. However, at this time, the status of the integration plans and the related merger-related costs are too uncertain to include in the pro forma financial information.
      Based on Thermo’s review of Fisher’s summary of significant accounting policies disclosed in Fisher’s financial statements, the nature and amount of any adjustments to the historical financial statements of Fisher to conform their accounting policies to those of Thermo are not expected to be significant. Upon consummation of the merger, further review of Fisher’s accounting policies and financial statements may result in required revisions to Fisher’s policies and classifications to conform to Thermo’s.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements
1. Basis of Presentation
      The unaudited pro forma condensed combined balance sheet was prepared using the historical balance sheets of Thermo as of April 1, 2006 and Fisher as of March 31, 2006. The unaudited pro forma condensed combined statements of income were prepared using the historical statements of income of Thermo for the three months ended April 1, 2006 and for the year ended December 31, 2005; of Kendro for the period from January 1, 2005 to May 8, 2005; and of Fisher for the three months ended March 31, 2006 and for the year ended December 31, 2005.
      The unaudited pro forma condensed combined financial information was prepared using the purchase method of accounting. As discussed under “Accounting Treatment” on page 48, based upon the terms of the merger and other factors, such as the composition of the combined company’s board and senior management, Thermo is treated as the acquirer of Fisher. Accordingly, we have adjusted the historical consolidated financial information to give effect to the impact of the consideration issued in connection with the merger. In the unaudited pro forma condensed combined balance sheet, Thermo’s cost to acquire Fisher has been allocated to the assets acquired and liabilities assumed based upon management’s preliminary estimate of their respective fair values as of the date of the merger. Any differences between fair value of the consideration issued and the fair value of the assets and liabilities acquired will be recorded as goodwill. The amounts allocated to acquired assets and liabilities in the unaudited pro forma condensed combined financial statements are based on management’s preliminary internal valuation estimates. Definitive allocations will be performed and finalized based on certain valuations and other studies that will be performed by Thermo with the services of outside valuation specialists after the closing of the merger. Accordingly, the purchase price allocation adjustments and related amortization reflected in the foregoing unaudited pro forma condensed combined financial statements are preliminary, have been made solely for the purpose of preparing these statements and are subject to revision based on a final determination of fair value after the closing of the merger. For example, if the value of the definite-lived intangible assets increased by 10%, annual pro forma income from continuing operations would decrease by $41 million.
2. Purchase Price
      The following is a preliminary estimate of the purchase price for Fisher:
                   
        (In millions)
Estimated number of Fisher shares to be acquired (in thousands)(a)
    125,911          
Exchange ratio
    2.00          
             
Number of shares of Thermo to be issued to the holders of Fisher stock (in thousands)
    251,822          
Multiplied by the assumed price per share of Thermo common stock(b)
  $ 38.93     $ 9,803.4  
Estimated fair value of outstanding Fisher stock options to be exchanged for Thermo stock options
            373.4  
Estimated transaction costs
            112.3  
             
 
Estimated purchase price
          $ 10,289.1  
             
      For purposes of this pro forma analysis, the above purchase price has been allocated based on a preliminary estimate of the fair value of net assets acquired.

        (C) To eliminate Fisher’s existing goodwill, intangible assets, related deferred tax liability and amortization of the intangible assets.
 
        (D) To record goodwill and $4.9 billion of acquired intangible assets ($3.8 billion with definite lives and $1.1 billion with indefinite lives), and amortization of definite-lived intangible assets over a weighted average life of 6 years.

        (F) To adjust Fisher’s pension and other post-retirement obligations and any associated assets to fair value.
 
        (G) To adjust Fisher’s long-term debt to fair value, write-off Fisher’s deferred financing costs and record the related adjustment to interest expense, and to increase stockholders’ equity for the fair value attributable to the beneficial conversion features of Fisher’s convertible debt.
 
        (H) To remove the historical equity accounts of Fisher.

THE THERMO SPECIAL MEETING
Date, Time and Place
      The special meeting of Thermo stockholders will be held at Thermo’s principal executive offices at 81 Wyman Street, Waltham, Massachusetts 02451, on August 30, 2006 at 10:00 a.m., local time.
Purpose of the Thermo Special Meeting
      At the Thermo special meeting, stockholders will be asked to:
  •  consider and vote on a proposal to approve the issuance of Thermo common stock in connection with the merger;
 
  •  consider and vote on a proposal to amend the Amended and Restated Certificate of Incorporation of Thermo, effective upon the completion of the merger, to increase the authorized number of shares of Thermo common stock from 350,000,000 to 1.2 billion and to change the name of Thermo Electron Corporation upon the completion of the merger to Thermo Fisher Scientific Inc.;
 
  •  vote upon an adjournment of the Thermo special meeting, if necessary, to solicit additional proxies if there are not sufficient votes for each of the foregoing proposals; and
 
  •  transact any other business that may properly be brought before the Thermo special meeting or any adjournments or postponements thereof.
Thermo Record Date; Stock Entitled to Vote
      Only Thermo stockholders of record at the close of business on July 24, 2006, the Thermo record date for the Thermo special meeting, will be entitled to notice of, and to vote at, the Thermo special meeting or any adjournments or postponements thereof.
      On the Thermo record date, there were a total of                      shares of Thermo common stock outstanding and entitled to vote at the Thermo special meeting. Thermo stockholders will have one vote for each share of Thermo common stock that they owned on the Thermo record date, exercisable in person or through the Internet or by telephone or by a properly executed and delivered proxy with respect to the Thermo special meeting.
      On the record date, directors and executive officers of Thermo and their affiliates owned and were entitled to vote                shares of Thermo common stock, or approximately      % of the shares of Thermo common stock outstanding on that date. We currently expect that Thermo’s directors and executive officers will vote their shares in favor of the issuance of Thermo common stock in connection with the merger and the Thermo charter amendment proposal, although none of them has entered into any agreements obligating them to do so.
Quorum
      The holders of shares having a majority of the voting power of the common stock of Thermo issued and outstanding and entitled to vote thereat must be present or represented by proxy to constitute a quorum for the transaction of business at the special meeting. All shares of Thermo common stock represented at the Thermo special meeting, including abstentions and broker non-votes, will be treated as present for purposes of determining the presence or absence of a quorum for all matters for consideration at the Thermo special meeting.

70


Table of Contents

Required Vote
      The proposals require different percentages of votes in order to approve them:
  •  The issuance of Thermo common stock to Fisher stockholders, approval of which is necessary to complete the merger, requires approval by an affirmative vote of holders of a majority of the Thermo common stock present or represented and entitled to vote on the proposal.
 
  •  The Thermo charter amendment proposal, approval of which is necessary to complete the merger, requires the affirmative vote of holders of a majority of the outstanding shares of Thermo common stock as of the record date.
 
  •  Approval of the proposal to adjourn the Thermo special meeting, if necessary, for the purpose of soliciting additional proxies requires that the votes cast favoring the proposal exceed the votes cast opposing the proposal.
Abstentions
      If you are a Thermo stockholder and fail to vote or vote to abstain:
  •  it will have the same effect as a vote against the Thermo charter amendment proposal, which is necessary to complete the merger; and
 
  •  it will have no effect on the proposal to approve the issuance of shares of Thermo common stock in the merger, assuming a quorum is present.
Voting of Proxies
      A proxy card is enclosed for your use. Thermo requests that you sign the accompanying proxy and return it promptly in the enclosed postage-paid envelope. When the accompanying proxy is returned properly executed, the shares of Thermo common stock represented by it will be voted at the Thermo special meeting or any adjournment thereof in accordance with the instructions contained in the proxy.
      If a proxy is returned without an indication as to how the shares of Thermo common stock represented are to be voted with regard to a particular proposal, the Thermo common stock represented by the proxy will be voted in favor of each such proposal. At the date hereof, management has no knowledge of any business that will be presented for consideration at the special meeting and which would be required to be set forth in this proxy statement or the related proxy card other than the matters set forth in the Notice of Special Meeting of Stockholders. If any other matter is properly presented at the special meeting for consideration, it is intended that the persons named in the enclosed form of proxy and acting thereunder will vote in accordance with their best judgment on such matter.
      Your vote is important. Accordingly, please sign and return the enclosed proxy card whether or not you plan to attend the Thermo special meeting in person.
Shares Held in Street Name
      If you hold your shares in a stock brokerage account or if your shares are held by a bank or nominee (that is, in street name), you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your bank or broker. Please note that you may not vote shares held in street name by returning a proxy card directly to Thermo or by voting in person at your stockholders’ meeting unless you provide a “legal proxy,” which you must obtain from your bank or broker. Further, brokers who hold shares of Thermo common stock on behalf of their customers may not give a proxy to Thermo to vote those shares without specific instructions from their customers.
      If you are a Thermo stockholder and you do not instruct your broker on how to vote your shares:
  •  your broker may not vote your shares on the Thermo charter amendment proposal, which will have the same effect as a vote against the Thermo charter amendment proposal; and

71


Table of Contents

  •  your broker may not vote your shares on the proposal to approve the issuance of shares of Thermo common stock in the merger, which will have no effect on the vote on this proposal, assuming a quorum is present.
Revocability of Proxies
      You have the power to revoke your proxy at any time before your proxy is voted at the Thermo special meeting. You can revoke your proxy in one of three ways:
  •  you can send a signed notice of revocation;
 
  •  you can grant a new, valid proxy bearing a later date; or
 
  •  if you are a holder of record, you can attend the Thermo special meeting and vote in person, which will automatically cancel any proxy previously given, or you can revoke your proxy in person, but your attendance alone will not revoke any proxy that you have previously given.
      If you choose either of the first two methods, you must submit your notice of revocation or your new proxy to Thermo’s Secretary at 81 Wyman Street, Waltham, Massachusetts 02451, no later than the beginning of the Thermo special meeting.
Solicitation of Proxies
      In accordance with the merger agreement, the cost of proxy solicitation for the Thermo special meeting will be borne by Thermo, except that Fisher and Thermo will share equally all expenses incurred in connection with the filing of the registration statement of which this document forms a part with the SEC and the printing and mailing of this document. In addition to the use of the mail, proxies may be solicited by officers and directors and regular employees of Thermo, without additional remuneration, by personal interview, telephone, facsimile or otherwise. Thermo will also request brokerage firms, nominees, custodians and fiduciaries to forward proxy materials to the beneficial owners of shares held of record on the record date and will provide customary reimbursement to such firms for the cost of forwarding these materials. Thermo has retained D.F. King & Co. and MacKenzie Partners to assist in its solicitation of proxies and has agreed to pay them in the aggregate approximately $45,000, plus reasonable expenses, for these services.

Any differences, therefore, in the rights of holders of Thermo capital stock and Fisher capital stock arise primarily from differences in their respective certificates of incorporation and bylaws. Upon completion of the merger, the certificate of incorporation and bylaws of Thermo in effect immediately prior to the effective time of the merger will be the certificate of incorporation and bylaws of the combined company, except for those changes to the Thermo charter and bylaws expressly contemplated by the merger agreement (including the Thermo charter amendment) and discussed below and under “The Thermo Special Meeting — Purpose of the Thermo Special Meeting” and “The Merger — Board of Directors and Management Following the Merger.” Consequently, after the effective time of the merger, the rights of the former stockholders of Fisher will be determined by reference to the Thermo charter and bylaws, each as amended.
         
    Rights of Fisher Stockholders   Rights of Thermo Stockholders
         
Corporate Governance   The rights of Fisher stockholders are currently governed by Delaware law and Fisher’s certificate of incorporation and bylaws. Upon completion of the merger, the rights of Fisher stockholders will continue to be governed by Delaware law but will be governed by Thermo’s certificate of incorporation and bylaws.   Upon completion of the merger, the rights of Thermo stockholders will be governed by Delaware law and Thermo’s certificate of incorporation and bylaws.
 
Outstanding Capital Stock   Fisher has outstanding only one class of common stock. Holders of Fisher common stock are entitled to all of the rights and obligations provided to common stockholders under Delaware law and Fisher’s certificate of incorporation and bylaws.   Thermo has outstanding only one class of common stock. Holders of Thermo common stock are entitled to all of the rights and obligations provided to common stockholders under Delaware law and Thermo’s certificate of incorporation and bylaws.
 
Authorized Capital Stock   The authorized capital stock of Fisher consists of 500,000,000 shares of common stock, $0.01 par value per share, and 15,000,000 shares of preferred stock, $0.01 par value per share. No shares of preferred stock are outstanding.   Thermo currently has authorized 350,000,000 shares of common stock, $1.00 par value per share. Following the merger, the authorized capital stock of Thermo will consist of 1.2 billion shares of common stock, $1.00 par value per share. The number of authorized preferred shares will remain unchanged at 50,000 shares of preferred stock, $100 par value per share. 40,000 shares of preferred stock are designated as Series B Junior Participating Preferred stock, $100 par value per share.

  board of directors, or the Chief Executive Officer.
Stockholder Action by Written Consent   As permitted under the DGCL, Fisher’s certificate of incorporation prohibits action by the written consent of Fisher stockholders. Any stockholder action must be taken at a duly called annual or special meeting of the stockholders.   Thermo’s bylaws provide that any action required or permitted to be taken by stockholders for or in connection with any corporate action may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action to be taken, is signed by the minimum number of votes required for the action.

If action is taken by less than unanimous consent of stockholders, prompt notice of the taking of such action without a meeting must be given to those stockholders who have not consented in writing.
Stockholder Proposals and Nominations of Candidates for Election to the Board of Directors   Fisher’s bylaws allow stockholders to propose business to be brought before an annual meeting. In addition, Fisher’s bylaws allow stockholders who are entitled to vote in the election of directors to nominate candidates for election to the Fisher board of directors.

However, such proposals with respect to an annual meeting and such nominations may only be brought by a stockholder who has given timely notice in proper written form to Fisher’s Secretary prior to the meeting.

To be timely, the notice must be delivered to or mailed and received at Fisher’s principal executive offices not less than 30 days nor more than 60 days prior to the meeting, unless less than 40 days’ notice or prior public disclosure of the date of the meeting is given or made to

However, proposals and nominations may only be brought before an annual meeting by a stockholder who has given timely notice in proper written form to Thermo’s Secretary prior to the meeting.

To be timely, the notice must be delivered to or mailed and received at Thermo’s principal executive offices not less than 60 days nor more than 75 days prior to the first anniversary of the date on which Thermo first mailed its proxy materials for the

    Fisher stockholders, in which case the notice, to be timely, must be received not later than the close of business on the 10th day following the day on which notice of the date of the meeting was mailed or publicly disclosed.

To be in proper written form, notice of a stockholder proposal must provide:

• A brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting;

• The name and address, as they appear in Fisher’s books, of the stockholder proposing such business;

• The class and number of shares of Fisher stock which are beneficially owned by the stockholder; and

• Any material interest of the stockholder in such business.

To be in proper written form, notice of a stockholder nomination must provide:

• All information relating to the person to be nominated that is required to be disclosed in solicitations of proxies for the election of directors pursuant to the proxy rules of the SEC, including such person’s written consent to being named as a nominee and to serving as a director if elected;

• The name and address, as they appear on Fisher’s books, of the stockholder making the nomination; and

• The class and number of shares of Fisher which are beneficially owned by such stockholder.

    Fisher’s Secretary must appoint inspectors to determine whether a stockholder making a nomination has complied with these procedural requirements. The inspectors may determine, and direct the chairman of the meeting to declare, that the nomination has not been properly brought or made and disregard it. The chairman of an annual meeting may, in the case of a stockholder proposal, determine that the proposal has not been properly brought or made and disregard it.    
Number of Directors   The DGCL provides that the board of directors of a Delaware corporation must consist of one or more directors as fixed by the corporation’s certificate of incorporation or bylaws.

Fisher’s bylaws provide that Fisher’s board of directors may consist of no less than three and no more than 15 directors, the exact number of authorized directors to be determined from time to time by the vote of a majority of the then authorized number of directors or by the affirmative vote of the holders of at least 80% of the voting power of the outstanding shares of capital stock of Fisher entitled to vote in the election of directors, voting together as a single class. The minimum and maximum number of directors may be increased pursuant to a resolution of the board of directors upon the establishment of a series of preferred stock or a class of common stock.
  Following the merger, Thermo’s bylaws will provide that the board of directors, for a period of three years following the merger, will consist of eight directors, five directors selected by Thermo and three directors selected by Fisher.

After the three year period following the merger, the number of directors may be increased at any time by resolution of the board of directors. The board of directors may be decreased from time to time by a majority of the directors then in office, but only to eliminate vacancies existing by reason of death, resignation, removal or expiration of the term of one or more directors.
Classification of Board of Directors   The DGCL permits a Delaware corporation to provide in its certificate of incorporation or bylaws for the board of directors to be divided into up to three classes of directors with staggered terms of office, with only one class of directors to be elected each year for a maximum term of three years.   Thermo’s bylaws provide that the board of directors is divided into three separate classes, as nearly equal in number as possible, with staggered three-year terms. At each annual meeting of stockholders, directors elected to succeed those directors whose terms expire shall be elected for a three-year term.

    Fisher’s certificate of incorporation divides the board of directors into three separate classes, as nearly equal in number as possible, with staggered three-year terms. At each annual meeting of stockholders, directors elected to succeed those directors whose terms expire shall be elected for a three-year term.    
Removal of Directors   Under the DGCL, stockholders holding a majority of shares entitled to vote at an election of directors may remove any director or the entire board of directors, except that, unless the certificate of incorporation provides otherwise, in the case of a corporation whose board of directors is classified, stockholders may only remove a director for cause.

Fisher’s certificate of incorporation and bylaws provide that a director may be removed from office by stockholders only for cause by the affirmative vote of the holders of at least 80% of the voting power of the outstanding shares of capital stock of Fisher entitled to vote in the election of directors, voting together as a single class.
  Thermo is governed by the default DGCL provisions with respect to removal of directors, which means that Thermo’s directors can only be removed for cause.
Filling Director Vacancies   Under the DGCL, unless a corporation’s certificate of incorporation and bylaws provide otherwise, vacancies and newly created directorships resulting from a resignation, an increase in the authorized number of directors or otherwise may be filled by a vote of a majority of the directors remaining in office, even if such majority is less than a quorum, or by the sole remaining director.

Fisher’s certificate of incorporation and bylaws do not provide otherwise. In addition, they specify that any director elected in accordance with the above shall hold office until the annual meeting of stockholders at
  For three years following the merger, if there is a vacancy created by the cessation of service by a continuing Thermo director, a majority of the remaining continuing Thermo directors will propose a nominee to fill the vacant position. Similarly, if there is a vacancy created by the cessation of service by a continuing Fisher director, a majority of the remaining continuing Fisher directors will propose a nominee to fill the vacant position.

After the three year period following the merger, Thermo’s bylaws will provide that any vacancy in the board of directors, however occurring, or any newly

    which the term of office of the class to which such director has been elected expires, and until such director’s successor shall have been duly elected and qualified.   created directorship resulting from an enlargement in the size of the board, will be filled only by vote of a majority of the directors then in office, even if less than a quorum, or by the sole remaining director and not by the stockholders.

A director elected to fill a vacancy will be elected for the unexpired term of such director’s predecessor in office, and a director chosen to fill a newly created directorship will hold office until the next election for the class which such director is chosen, subject in each case to the election and qualification of the director’s successor and to the director’s earlier death, resignation or removal.
Indemnification of Directors and Officers   Under the DGCL, a Delaware corporation must indemnify its present or former directors and officers against expenses (including attorney’s fees) actually and reasonably incurred to the extent that the officer or director has been successful on the merits or otherwise in defense of any action, suit or proceeding brought against him or her by reason of the fact that he or she is or was a director or officer of the corporation.

The DGCL generally permits a Delaware corporation to indemnify directors and officers against expenses, judgments, fines and amounts paid in settlement of any action or suit for actions taken in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action, which they had no reasonable cause to believe was unlawful.

Fisher’s certificate of incorporation provides that each person who was or is made a party or is threatened to be made
  Thermo’s certificate of incorporation provides that each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director or officer of Thermo is indemnified and held harmless by Thermo to the fullest extent authorized by the DGCL against all expense, liability and loss (including attorneys’ fees, judgments, fines and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person in connection with such proceeding.

Thermo is governed by the same provisions of the DGCL, permitting Thermo to purchase director’s and officer’s insurance to protect itself and any director, officer, employee or agent of Thermo.

    a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director or officer of Fisher will be indemnified and held harmless by Fisher to the fullest extent authorized by the DGCL against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection with such proceeding. In addition, Fisher may provide indemnification to employees and agents of Fisher to the same extent.

The DGCL and Fisher’s certificate of incorporation permit Fisher to purchase and maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of Fisher or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not Fisher would have the power to indemnify such person against such expense, liability or loss under the DGCL.
   
Amendments to Certificate or Articles of Incorporation   Under the DGCL, Fisher’s certificate of incorporation may be amended only if the proposed amendment is approved by the board of directors and the holders of a majority of the outstanding stock entitled to vote.

In addition, Fisher’s certificate of incorporation requires the affirmative vote of the holders of at least 80% of the voting power of the outstanding shares of capital stock of Fisher entitled to vote in the election of directors, voting together as a single class, in order to approve amendments to Fisher’s certificate of incorporation relating to:
  Thermo’s certificate of incorporation reserves the right to amend, alter, change or repeal any provision contained in the certificate of incorporation in the manner prescribed by the DGCL.

    • The authority to amend or repeal certain provisions of Fisher’s bylaws;

• The prohibition on stockholder voting by written consent;

• Calling special meetings of stockholders;

• The structure and composition of the board of directors;

• Filling vacancies on the board of directors; or

• The removal of directors.
   
Amendments to Bylaws   Fisher’s certificate of incorporation and bylaws provide that Fisher’s bylaws may be amended, supplemented or repealed, or new bylaws may be adopted, by the board of directors or by the stockholders. In addition, stockholders may change or repeal any bylaw adopted by the board of directors, and no amendment or supplement to the bylaws adopted by the board of directors shall vary or conflict with any amendment or supplement adopted by the stockholders.

Certain bylaws shall not be amended or repealed, and no provision inconsistent with them shall be adopted, without the affirmative vote of the holders of at least 80% of the voting power of the outstanding shares of capital stock of Fisher entitled to vote in the election of directors, voting together as a single class. These bylaws relate to:

• Calling special meetings of stockholders;

• The structure and composition of the board of directors; and

• The removal of directors.
  Thermo’s bylaws provide that Thermo’s bylaws may be altered, amended, or repealed, or new bylaws may be adopted, by the board of directors or by the stockholders. The stockholders have the power to amend, alter, and repeal any provision of the bylaws by an affirmative vote of the holders of a majority of the shares of capital stock entitled to vote, voting together as a single class.

Certain bylaws cannot be altered, amended or repealed, or made new, by the stockholders, in a manner inconsistent with the existing bylaws, without the affirmative vote of the holders of at least 662/3% of the voting power of the outstanding shares of capital stock of Thermo entitled to vote, voting together as a single class. These bylaws relate to:

• the board of directors; and

• amendments to the bylaws.

Following the merger and until the third anniversary of the closing, any amendment or change to the five Thermo to three Fisher director ratio and the vacancy provisions described above, will require the affirmative vote of 75% of the full board of

        directors of the combined company.
Business Combination Statute   Section 203 of the DGCL prohibits a Delaware corporation from engaging in a “business combination” with a person owning 15% or more of the corporation’s voting stock for three years following the time that person becomes a 15% stockholder, with certain exceptions.

As permitted under Delaware law, Fisher has expressly elected not to be governed by Section 203 in its certificate of incorporation.
  Thermo has not opted out of Section 203 and is therefore governed by the default terms of this provision of the DGCL.
 
Stockholder Rights Plan   Fisher does not have a stockholder rights plan.   Thermo’s rights plan entitles the registered holder to a “right” to purchase from the Thermo a unit consisting of one one-hundred-thousandth of a share of Series B Junior Participating Preferred Stock, par value $100 per share, at a purchase price of $200 in cash per unit, subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement dated as of September 15, 2005 between Thermo and American Stock Transfer & Trust Company, as rights agent.

Under the agreement, if any person commences a tender or exchange offer, the consummation of which would result in such person becoming the beneficial owner of 15% or more of the outstanding shares of Thermo common stock, or thereafter Thermo is involved in a merger or other business combination in which 50% or more of Thermo’s assets or earning power is sold, each right entitles its holder to receive, upon exercise, Thermo common stock (or, in the case of a merger or other business combination, stock of the acquiring company) having a value equal to two times the exercise price of the right.

85


Table of Contents

         
    Rights of Fisher Stockholders   Rights of Thermo Stockholders
         
        Upon exercise, each share of preferred stock will be entitled to a minimum preferential quarterly dividend payment of $100 per share and will be entitled to an aggregate dividend of 100,000 times the dividend declared per share of common stock. In the event of liquidation, the holders of the preferred stock will be entitled to a minimum preferential liquidating payment of $100 per share and will be entitled to an aggregate payment of 100,000 times the payment made per share of common stock. Each share of preferred stock will have 100,000 votes, voting together with the common stock. Finally, in the event of any merger, consolidation or other transaction in which common stock is changed or exchanged, each share of preferred stock will be entitled to receive 100,000 times the amount received per share of common stock. These rights are protected by customary anti-dilution provisions.

Because of the nature of the preferred stock’s dividend, liquidation and voting rights, the value of one one-hundred- thousandth of a share of preferred stock purchasable upon exercise of each right should approximate the value of one share of common stock.

The rights have certain anti- takeover effects. The rights will cause substantial dilution to a person or group that attempts to acquire Thermo without conditioning the offer on a substantial number of rights being acquired.

The rights, however, should not affect any prospective offeror willing to make a permitted offer. The rights should not interfere with any merger or other business combination approved by the board of directors of

        Thermo since the board of directors may, at its option, redeem all but not less than all of the then outstanding rights for a nominal redemption price ($0.01 per right).

The rights agreement contains a so-called “TIDE” provision, which requires that a stockholder rights plan committee of the board of directors of Thermo shall review (not less than once every three years) whether maintaining the rights agreement continues to be in the best interest of the stockholders.

On May 7, 2006, Thermo amended its rights agreement to exempt the merger and the other transactions contemplated by the merger agreement from the effect of the rights agreement.

The rights will expire at the close of business on September 29, 2015, unless earlier redeemed or exchanged by Thermo.

STOCKHOLDER PROPOSALS
Thermo
      Proposals of stockholders intended to be included in the proxy statement and proxy card relating to the 2007 Annual Meeting of Stockholders of Thermo and to be presented at such meeting must be received by Thermo for inclusion in the proxy statement and proxy card no later than December 12, 2006. In addition, Thermo’s bylaws include an advance notice provision that requires stockholders desiring to bring proposals before an annual meeting (which proposals are not to be included in Thermo’s proxy statement and thus are submitted outside the processes of Rule 14a-8 under the Exchange Act) to do so in accordance with the terms of such advance notice provision. The advance notice provision requires that, among other things, stockholders give timely written notice to the Secretary of Thermo regarding their proposals. To be timely, notices must be delivered to the Secretary at the principal executive office of Thermo not less than 60, nor more than 75, days prior to the first anniversary of the date on which Thermo mailed its proxy materials for the preceding year’s annual meeting of stockholders. Accordingly, a stockholder who intends to present a proposal at the 2007 Annual Meeting of Stockholders without inclusion of the proposal in Thermo’s proxy materials must provide written notice of such proposal to the Secretary no earlier than January 26, 2007, and no later than February 10, 2007. Proposals received at any other time will not be voted on at the meeting. If a stockholder makes a timely notification, the proxies that management solicits for the meeting may still exercise discretionary voting authority with respect to the stockholder’s proposal under circumstances consistent with the proxy rules of the SEC.
Fisher
      If the merger is not consummated, Fisher will hold a 2007 Annual Meeting of Stockholders. Stockholders may submit proposals on matters appropriate for stockholder action at Fisher’s annual meetings, consistent with regulations adopted by the SEC and the bylaws of Fisher. Proposals to be considered for inclusion in the proxy statement for the 2007 Annual Meeting must be received by Fisher at its principal executive offices not later than December 8, 2006. Proposals to be timely submitted for stockholder action at Fisher’s 2007 Annual Meeting must be received by Fisher at its principal executive offices not less than 30 days nor more than 60 days prior to the 2007 Annual Meeting (or, if less than 40 days’ notice or prior public disclosure of the date of the 2007 Annual Meeting is given or made, not later than the tenth day following the date on which such notice was mailed or public disclosure was made).

      (a) Conversion of Fisher Common Stock. Subject to Sections 2.1(f) and 2.1(g), each share of Fisher Common Stock issued and outstanding immediately prior to the Effective Time, other than any shares of Fisher Common Stock to be canceled pursuant to Section 2.1(c), shall be automatically converted into and become the right to receive 2.0 (the “Exchange Ratio”) fully paid and nonassessable shares of common stock, par value $1.00 per share (“Thermo Electron Common Stock”), of Thermo Electron (the “Merger Consideration”).

      (d) Fisher Options, Stock Unit Awards and Employee Stock Purchase Plans. At the Effective Time, (i) subject to and in accordance with Section 5.11(a), all options to purchase Fisher Common Stock (each, a “Fisher Option”) and all restricted stock units and rights to receive shares of Fisher Common Stock or an amount in cash measured by the value of a number of shares of Fisher Common Stock (each, a “Fisher Stock Unit Awards”), in each case, issued and outstanding at the Effective Time under a Fisher Stock Plan or a Fisher Deferred Compensation Plan (each as defined in Section 3.1(b)(i)), shall be assumed by Thermo Electron and (ii) all rights outstanding under Fisher’s Employee Stock Purchase Plan, as approved by the Fisher stockholders on May 5, 2006 (the “Fisher Purchase Plan”), shall be treated as set forth in Section 5.11(b).
      (e) Conversion of Debt. The Fisher Convertible Debentures (as defined in Section 3.1(b)(i)) shall remain outstanding as debentures of Fisher, however in lieu of being convertible into shares of Fisher Common Stock, following the Effective Time, the Fisher Convertible Debentures shall become convertible into Thermo Electron Common Stock at a conversion ratio equal to the conversion ratio in effect immediately prior to the Effective Time multiplied by the Exchange Ratio and Thermo Electron shall agree to guarantee the payment of, or become a co-obligor on, said debentures.
      (f) Fractional Shares. No fraction of a share of Thermo Electron Common Stock will be issued by virtue of the Merger, but in lieu thereof each holder of shares of Fisher Common Stock who would otherwise be entitled to a fraction of a share of Thermo Electron Common Stock (after aggregating all shares of Thermo Electron Common Stock that otherwise would be received by such holder) shall, upon surrender of such holder’s Certificate or Certificates, receive from Thermo Electron an amount of cash (rounded to the nearest whole cent), without interest, equal to the product of: (i) the fractional share interest (after aggregating all shares of Thermo Electron Common Stock that would otherwise be received by such holder) which such holder would otherwise receive, multiplied by (ii) the closing price of one share of Thermo Electron Common Stock on the New York Stock Exchange (“NYSE”) Composite Transactions Tape ending on the trading day one day prior to the Effective Time.
      (g) Adjustments to Exchange Ratio. The Exchange Ratio and the Merger Consideration shall be adjusted to reflect fully the appropriate effect of any stock split, split-up, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Thermo Electron Common Stock or Fisher Common Stock), reorganization, recapitalization, reclassification or other like change with respect to Thermo Electron Common Stock or Fisher Common Stock having a record date occurring on or after the date hereof and prior to the Effective Time.
      Section 2.2.     Exchange of Shares and Certificates.
      (a) Exchange Agent. At or prior to the Effective Time, Thermo Electron shall engage an institution reasonably satisfactory to Fisher (and Thermo Electron’s transfer agent shall be deemed satisfactory to Fisher) to act as exchange agent in connection with the Merger (the “Exchange Agent”), pursuant to an agreement reasonably satisfactory to Fisher. At the Effective Time, Thermo Electron shall deposit with the Exchange Agent, in trust for the benefit of the holders of shares of Fisher Common Stock immediately prior to the Effective Time, certificates representing the shares of Thermo Electron Common Stock issuable pursuant to Section 2.1(a). In addition, Thermo Electron shall make available by depositing with the Exchange Agent, as necessary from time to time after the Effective Time, cash in an amount sufficient to make the payments in lieu of fractional shares pursuant to Section 2.1(f) and any dividends or distributions to which holders of shares of Fisher Common Stock may be entitled pursuant to Section 2.2(c). All cash and certificates representing shares of Thermo Electron Common Stock deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

Promptly after the Effective Time, and in any event within 10 business days after the Effective Time, Thermo Electron shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Fisher Common Stock (the “Certificates”), which at the Effective Time were converted into the right to receive the Merger Consideration pursuant to Section 2.1 hereof, (i) a letter of transmittal (which shall specify that delivery shall be effected, and that risk of loss and title to the Certificates shall pass only upon

A-4


Table of Contents

delivery of the Certificates to the Exchange Agent and which shall be in form and substance reasonably satisfactory to Thermo Electron and Fisher) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing whole shares of Thermo Electron Common Stock, cash in lieu of any fractional shares pursuant to Section 2.1(f)and any dividends or other distributions payable pursuant to Section 2.2(c). Upon surrender of Certificates for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificates shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Thermo Electron Common Stock (after taking into account all Certificates surrendered by such holder) to which such holder is entitled pursuant to Section 2.1 (which shall be in uncertificated book entry form unless a physical certificate is requested), payment by cash or check in lieu of fractional shares which such holder is entitled to receive pursuant to Section 2.1(f) and any dividends or distributions payable pursuant to Section 2.2(c), and the Certificates so surrendered shall forthwith be canceled. In the event of a transfer of ownership of shares of Fisher Common Stock which is not registered in the transfer records of Fisher, a certificate representing the proper number of shares of Thermo Electron Common Stock may be issued to a Person (as defined in Section 8.3(l)) other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such issuance shall pay any transfer or other Taxes (as defined in Section 3.1(j)(xi)) required by reason of the issuance of shares of Thermo Electron Common Stock to a Person other than the registered holder of such Certificate or establish to the reasonable satisfaction of Thermo Electron that such Tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.2(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration (and any amounts to be paid pursuant to Section 2.1(f) or Section 2.2(c)) upon such surrender. No interest shall be paid or shall accrue on any amount payable pursuant to Section 2.1(f) or Section 2.2(c).
      (c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to shares of Thermo Electron Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Thermo Electron Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.1(f) hereof, until such Certificate has been surrendered in accordance with this Article II. Subject to Applicable Laws, following surrender of any such Certificate, there shall be paid to the recordholder thereof, without interest, (i) promptly after such surrender, the number of whole shares of Thermo Electron Common Stock issuable in exchange therefor pursuant to this Article II, together with any cash payable in lieu of a fractional share of Thermo Electron Common Stock to which such holder is entitled pursuant to Section 2.1(f) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Thermo Electron Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time and a payment date subsequent to such surrender payable with respect to such whole shares of Thermo Electron Common Stock.
      (d) No Further Ownership Rights in Fisher Common Stock. All shares of Thermo Electron Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms of this Article II and any cash paid pursuant to Section 2.1(f) or Section 2.2(c) shall be deemed to have been issued (or paid) in full satisfaction of all rights pertaining to the shares of Fisher Common Stock previously represented by such Certificates. After the Effective Time, the stock transfer books of Fisher shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Fisher Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article II.
      (e) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates one year after the Effective Time shall be delivered to Thermo Electron, upon demand, and any holders of Certificates who have not theretofore complied with this Article II shall thereafter

Table of Contents

look only to Thermo Electron for payment of their claim for the Merger Consideration, any cash in lieu of fractional shares of Thermo Electron Common Stock pursuant to Section 2.1(f) and any dividends or distributions pursuant to Section 2.2(c).
      (f) No Liability. None of Thermo Electron, Merger Sub, Fisher or the Exchange Agent or any of their respective directors, officers, employees and agents shall be liable to any Person in respect of any shares of Thermo Electron Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to seven years after the Effective Time, or immediately prior to such earlier date on which any shares of Thermo Electron Common Stock, any cash in lieu of fractional shares of Thermo Electron Common Stock or any dividends or distributions with respect to Thermo Electron Common Stock issuable in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity (as defined in Section 3.1(c)(v)), any such shares, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by Applicable Laws, become the property of the Surviving Corporation, free and clear of all claims or interests of any Person previously entitled thereto.
      (g) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Thermo Electron on a daily basis, provided, that no such investment or loss thereon shall affect the amounts payable to former stockholders of Fisher after the Effective Time pursuant to this Article II. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable pursuant to this Article II shall promptly be paid to Thermo Electron.
      (h) Withholding Rights. Thermo Electron and the Exchange Agent shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement to any Person who was a holder of Fisher Common Stock immediately prior to the Effective Time such amounts as Thermo Electron or the Exchange Agent may be required to deduct and withhold with respect to the making of such payment under the Code or any other provision of federal, state, local or foreign Tax law. To the extent that amounts are so withheld by Thermo Electron or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person to whom such consideration would otherwise have been paid.
      (i) Lost, Stolen or Destroyed Certificates. In the event any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof, such shares of Thermo Electron Common Stock as may be required pursuant to Section 2.1(a), cash for fractional shares pursuant to Section 2.1(f) and any dividends or distributions payable pursuant to Section 2.2(c); provided, however, that Thermo Electron may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to deliver an agreement of indemnification in form reasonably satisfactory to Thermo Electron, or a bond in such sum as Thermo Electron may reasonably direct as indemnity, against any claim that may be made against Thermo Electron or the Exchange Agent in respect of the Certificates alleged to have been lost, stolen or destroyed.

      (i) Section 3.1(i)(i)(A) of the Fisher Disclosure Schedule sets forth a true and complete list of each material bonus, pension, profit sharing, deferred compensation, incentive compensation, stock ownership, stock purchase, stock option or other equity compensation, phantom stock, stock-related or performance award, retirement, vacation, severance or termination pay, change in control, retention, disability, death benefit, hospitalization, medical, life insurance, loan, disability, and other similar material plan, arrangement, agreement or understanding, including, without limitation, each “employee benefit plan” (or similar plan) within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or any other comparable Applicable Law, whether or not subject to ERISA or such comparable Applicable Law, and any material employment agreement, consulting agreement, termination or severance agreement (such plans, agreements, arrangements or understandings, except any plan which is a Multiemployer Plan (as defined in Section 8.3(j)), collectively, “Benefit Plans”) with or for the benefit of any current or former employee, officer or director of Fisher or any of its Subsidiaries or ERISA Affiliates (as defined in Section 3.1(i)(v)) or with respect to which Fisher or any of its Subsidiaries or ERISA Affiliates have any material obligations or liabilities, including each material Benefit Plan that has been adopted or maintained by Fisher, any of its Subsidiaries or any Affiliate, whether formally or informally, or with respect to which Fisher, any of its Subsidiaries or any Affiliate will or may have any material liability, for the benefit of employees or consultants of Fisher or any of its Subsidiaries who perform services outside the United States (collectively, the “Fisher Benefit Plans”). With respect to the Fisher Benefit Plans, no event has occurred, and there exists no condition or set of circumstances, which would reasonably be expected to have a Material Adverse Effect on Fisher and its Subsidiaries, taken as a whole, under ERISA, the Code or any other Applicable Laws. Neither Fisher, nor any of its Subsidiaries, nor, to the Knowledge of Fisher, any other Person, has any express commitment, whether legally enforceable or not, to modify, change or terminate any Fisher Benefit Plan, other than with respect to a modification, change or termination required by ERISA or the Code, or any other Applicable Law or administrative changes that do not increase the liabilities or obligations under any such plans. Fisher has delivered or made available to Thermo Electron true, correct and complete copies of all Fisher Benefit Plans and, with respect thereto, if applicable, all amendments, trust agreements, insurance contracts, other funding vehicles, determination letters issued by the Internal Revenue Service (the “IRS”), the most recent annual reports (Form 5500 series) filed with the IRS and the most recent actuarial report or other financial statement relating to such Fisher Benefit Plan.
      (ii) Each Fisher Benefit Plan has been, in all material respects, administered and operated in accordance with its terms, with the applicable provisions of ERISA, the Code and other Applicable Laws and with the terms of all applicable collective bargaining agreements. Each Fisher Benefit Plan, including any material amendments thereto, that is required to obtain approval by, or registration or qualification for special tax status with, the appropriate taxation, social security or supervisory authorities in the relevant country, state, territory or the like (each, an “Approval”) has received such Approval (or there remains a period of time in which to obtain such Approval retroactive to the date of any material amendment that has not previously received such Approval), and no event has occurred which would reasonably be expected to result in the revocation of such Approval or the imposition of material sanctions by such authorities. Without limiting the generality of the foregoing, each Fisher Benefit Plan that is intended to be qualified under Section 401(a) of the Code has obtained a favorable determination letter from the IRS that the Fisher Benefit Plan is so qualified and all related trusts are exempt from U.S. federal income taxation under Section 501(a) of the Code, and, to the

A-14


Table of Contents

Knowledge of Fisher, nothing has occurred, whether by action or by failure to act, which would reasonably be expected to cause the loss of such qualification or exemption.
      (iii) As of the date hereof to the Knowledge of Fisher, no oral or written representation or commitment with respect to any material aspect of any Fisher Benefit Plan has been made to an employee or former employee of Fisher or any of its Subsidiaries by an authorized Fisher employee that is not materially in accordance with the written or otherwise pre-existing terms and provisions of such Fisher Benefit Plans. As of the date hereof, to the Knowledge of Fisher, neither Fisher nor any of its Subsidiaries has entered into any agreement, arrangement or understanding, whether written or oral, with any trade union, works council or other employee representative body or any material number or category of its employees which would prevent, restrict or materially impede the implementation of any layoff, redundancy, severance or similar program within its or their respective workforces (or any part of them).
      (iv) There are no material unresolved claims or disputes under the terms of, or in connection with, any Fisher Benefit Plan (other than routine undisputed claims for benefits), and no action, legal or otherwise, has been commenced or threatened with respect to any material claim or otherwise in connection with a Fisher Benefit Plan.
      (v) With respect to each Funded Retirement Plan (as defined in this Section 3.1(i)(v)) of Fisher or any of its Subsidiaries, the aggregate fair market value of the assets of such Funded Retirement Plan was, as of the most recently computed actuarial valuation of such plan, equal to or greater than the aggregate value of its liabilities assessed on an ongoing basis and calculated in accordance with the actuarial methods and assumptions used in such valuation pursuant to such Funded Retirement Plan and Applicable Law and GAAP. For purposes of this Agreement, “Funded Retirement Plan” means, with respect to a party, a Benefit Plan that is a “pension plan” within the meaning of Section 3(2) of ERISA that is subject to ERISA and under which the assets to satisfy the benefit obligations are legally segregated from the general assets of such party or any of its Subsidiaries and are not subject to the creditors of such party or any of its Subsidiaries. None of Fisher or any other Person or entity under common control within the meaning of Section 414(b), (c), (m) or (o) of the Code (an “ERISA Affiliate”) with Fisher has incurred, or is reasonably expected to incur, any liability to a Funded Retirement Plan under Title IV of ERISA (other than for contributions not yet due) or to the Pension Benefit Guaranty Corporation (other than for payment of premiums not yet due) that, when aggregated with other such liabilities, would reasonably be expected to result in a material liability of Fisher and its Subsidiaries, taken as a whole, which liability has not been fully paid.
      (vi) Section 3.1(i)(vi) of the Fisher Disclosure Schedule sets forth a true and complete list of each Multiemployer Plan to which Fisher or any ERISA Affiliate of Fisher contributes or is required to contribute, or to which, or with respect to which, Fisher or any ERISA Affiliate of Fisher has any material liability. If any Fisher Multiemployer Plan is subject to Title IV of ERISA, then, (A) neither Fisher nor any ERISA Affiliate of Fisher has made or suffered a “complete withdrawal” or a “partial withdrawal,” as such terms are respectively defined in Sections 4203 and 4205 of ERISA (or any liability resulting therefrom has been satisfied in full), (B) no event has occurred that presents a material risk of a complete or partial withdrawal, (C) neither Fisher nor any ERISA Affiliate of Fisher has any contingent liability under Section 4204 of ERISA, (D) no circumstances exist that present a material risk that any such plan will go into reorganization, and (E) to the best of Fisher’s Knowledge, the aggregate withdrawal liability of Fisher and each ERISA Affiliate of Fisher computed as if a complete withdrawal by Fisher and any ERISA Affiliate of Fisher had occurred under each such Fisher Benefit Plan on the date hereof, would not reasonably be expected to result in a material liability to Fisher. No Fisher Benefit Plan subject to ERISA is a plan that has two or more contributing sponsors at least two of whom are not under common control, within the meaning of Section 4063 of ERISA.
      (vii) No Fisher Benefit Plan provides health benefits (whether or not insured) with respect to employees or former employees of Fisher or any of its Subsidiaries after retirement or other termination of service (other than coverage mandated by Applicable Laws or benefits, the full cost of which is borne by the employee or former employee).

      (viii) Neither the negotiation and execution of this Agreement nor the consummation of the transactions contemplated hereby will (either alone or upon the occurrence of any additional or subsequent events) constitute an event under any Fisher Benefit Plan (for this purpose, Fisher Benefit Plan (other than with respect to those Plans that are Fisher Foreign Plans) shall be determined without regard to whether any plan, agreement, policy, understanding or arrangement is material despite the use of such qualifier in Section 3.1(i)(i) for purposes of the definitions of Benefit Plan and Fisher Benefit Plan) that will or may result in any payment (whether of severance pay or otherwise), acceleration of payment, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any employee or former employee of Fisher or any of its Subsidiaries or limit the ability to amend, terminate or receive a reversion of assets from any Fisher Benefit Plan or related trust. There is no contract, agreement, plan or arrangement with an employee or former employee of Fisher to which Fisher or any of its Subsidiaries is a party as of the date of this Agreement that, individually or collectively and as a result of the transaction contemplated hereby (whether alone or upon the occurrence of any additional or subsequent events) would reasonably be expected to give rise to the payment of any amount that would not be deductible pursuant to Sections 280G or 162(m) of the Code.

Neither Fisher nor any of its Subsidiaries, nor, to Fisher’s Knowledge, any counterparty to any Fisher Material Contract, has violated any provision of, or committed or failed to perform any act which, with or without notice, lapse of time or both, would constitute a default under the provisions of any Fisher Material Contract, except in each case for those violations and defaults which, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on Fisher and its Subsidiaries, taken as a whole.

All of the improvements located on any Fisher Owned Real Property or Fisher Leased Real Property are in good condition and repair (subject to normal wear and tear) without any structural defects of any kind. Except as set forth in Section 3.1(s) of the Fisher Disclosure Schedule, each material lease with respect to the Fisher Leased Real Property is valid, unmodified and in full force and effect, and there are no material subleases with respect to the Fisher Leased Real Property.

      (t) Reorganization. As of the date of this Agreement, neither Fisher nor any of its Subsidiaries (a) has taken (or caused to be taken) any action or knows of any fact, agreement, plan or other circumstance that would reasonably be expected to prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code or (b) knows of any reason why all approvals required for the consummation of the transactions contemplated by this Agreement should not be obtained on a timely basis.
      Section 3.2.     Representations and Warranties of Thermo Electron and Merger Sub . Except as set forth in the disclosure schedule dated as of the date of this Agreement and executed and delivered by Thermo Electron and Merger Sub to Fisher concurrently with or prior to the execution and delivery by Thermo Electron and Merger Sub of this Agreement (the “Thermo Electron Disclosure Schedule”), Thermo Electron and Merger Sub represent and warrant to Fisher as set forth in this Section 3.2. Each disclosure set forth in the Thermo Electron Disclosure Schedule, and any other information included in the Thermo Electron Disclosure Schedule, is identified by reference to, or has been grouped under a heading referring to, a specific individual subsection of this Agreement and shall be deemed to be disclosed solely for purposes of, and shall qualify and be treated as an exception to, such subsection, except to the extent that disclosure in one subsection of the Thermo Electron Disclosure Schedule is specifically referred to in another subsection of the Thermo Electron Disclosure Schedule by appropriate cross-reference and except to the extent that the relevance of a disclosure in one subsection of the Thermo Electron Disclosure Schedule to another subsection of the Thermo Electron Disclosure Schedule is reasonably apparent. The parties hereby agree that no reference to or disclosure of any item or other matter in the Thermo Electron Disclosure Schedule shall be construed as an admission or indication that (1) such item or other matter is material, (2) such item or other matter is required to be referred to or disclosed in the Thermo Electron Disclosure Schedule or (3) any breach or violation of Applicable Laws or any Contract exists or has actually occurred.

      (i) Benefit Plans.
      (i) Section 3.2(i)(i)(A) of the Thermo Electron Disclosure Schedule sets forth a true and complete list of each material Benefit Plan as of the date hereof with or for the benefit of any current or former employee, officer or director of Thermo Electron or any of its Subsidiaries or ERISA Affiliates or with respect to which Thermo Electron or any of its Subsidiaries or ERISA Affiliates have any material obligations or liabilities, including each material Benefit Plan that has been adopted or maintained by Thermo Electron, any of its Subsidiaries or any Affiliate, whether formally or informally, or with respect to which Thermo Electron, any of its Subsidiaries or any Affiliate will or may have any material liability, for the benefit of employees or consultants of Thermo Electron or any of its Subsidiaries who perform services outside the United States (collectively, the “Thermo Electron Benefit Plans”). With respect to the Thermo Electron Benefit Plans, no event has occurred, and there exists no condition or set of circumstances, which would reasonably be expected to have a Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a whole, under ERISA, the Code or any other Applicable Laws. Neither Thermo Electron, nor any of its Subsidiaries, nor, to the Knowledge of Thermo Electron, any other Person, has any express commitment, whether legally enforceable or not, to modify, change or terminate any Thermo Electron Benefit Plan, other than with respect to a modification, change or termination required by ERISA or the Code, or any other Applicable Law or administrative changes that do not increase the liabilities or obligations under any such plans. Thermo Electron has delivered or made available to Fisher true, correct and complete copies of all Thermo Electron Benefit Plans and, with respect thereto, if applicable, all amendments, trust agreements, insurance contracts, other funding vehicles, determination letters issued by the IRS, the most recent annual reports (Form 5500 series) filed with the IRS and the most recent actuarial report or other financial statement relating to such Thermo Electron Benefit Plan.
      (ii) Each Thermo Electron Benefit Plan has been, in all material respects, administered and operated in accordance with its terms, with the applicable provisions of ERISA, the Code and other Applicable Laws and with the terms of all applicable collective bargaining agreements. Each Thermo Electron Benefit Plan, including any material amendments thereto, that is required to obtain Approval has received such Approval

A-30


Table of Contents

(or there remains a period of time in which to obtain such Approval retroactive to the date of any material amendment that has not previously received such Approval), and no event has occurred which would reasonably be expected to result in the revocation of such Approval or the imposition of material sanctions by such authorities. Without limiting the generality of the foregoing, each Thermo Electron Benefit Plan that is intended to be qualified under Section 401(a) of the Code has obtained a favorable determination letter from the IRS that the Thermo Electron Benefit Plan is so qualified and all related trusts are exempt from U.S. federal income taxation under Section 501(a) of the Code, and, to the Knowledge of Thermo Electron, nothing has occurred, whether by action or by failure to act, which would reasonably be expected to cause the loss of such qualification or exemption.
      (iii) As of the date hereof to the Knowledge of Thermo Electron, no oral or written representation or commitment with respect to any material aspect of any Thermo Electron Benefit Plan has been made to an employee or former employee of Thermo Electron or any of its Subsidiaries by an authorized Thermo Electron employee that is not materially in accordance with the written or otherwise pre-existing terms and provisions of such Thermo Electron Benefit Plans. As of the date hereof, to the Knowledge of Thermo Electron, neither Thermo Electron nor any of its Subsidiaries has entered into any agreement, arrangement or understanding, whether written or oral, with any trade union, works council or other employee representative body or any material number or category of its employees which would prevent, restrict or materially impede the implementation of any layoff, redundancy, severance or similar program within its or their respective workforces (or any part of them).
      (iv) There are no material unresolved claims or disputes under the terms of, or in connection with, any Thermo Electron Benefit Plan (other than routine undisputed claims for benefits), and no action, legal or otherwise, has been commenced or threatened with respect to any material claim or otherwise in connection with a Thermo Electron Benefit Plan.
      (v) With respect to each Funded Retirement Plan of Thermo Electron or any of its Subsidiaries, the aggregate fair market value of the assets of such Funded Retirement Plan was, as of the most recently computed actuarial valuation of such plan, equal to or greater than the aggregate value of its liabilities assessed on an ongoing basis and calculated in accordance with the actuarial methods and assumptions used in such valuation pursuant to such Funded Retirement Plan and Applicable Law and GAAP. None of Thermo Electron or any ERISA Affiliate of Thermo Electron has incurred, or is reasonably expected to incur, any liability to a Funded Retirement Plan under Title IV of ERISA (other than for contributions not yet due) or to the Pension Benefit Guaranty Corporation (other than for payment of premiums not yet due) that, when aggregated with other such liabilities, would reasonably be expected to result in a material liability of Thermo Electron and its Subsidiaries, taken as a whole, which liability has not been fully paid.
      (vi) Section 3.1(i)(vi) of the Thermo Electron Disclosure Schedule sets forth a true and complete list of each Multiemployer Plan to which Thermo Electron or any ERISA Affiliate of Thermo Electron contributes or is required to contribute, or to which, or with respect to which, Thermo Electron or any ERISA Affiliate of Thermo Electron has any material liability. If any Thermo Electron Multiemployer Plan is subject to Title IV of ERISA, then, (A) neither Thermo Electron nor any ERISA Affiliate of Thermo Electron has made or suffered a “complete withdrawal” or a “partial withdrawal,” as such terms are respectively defined in Sections 4203 and 4205 of ERISA (or any liability resulting therefrom has been satisfied in full), (B) no event has occurred that presents a material risk of a complete or partial withdrawal, (C) neither Thermo Electron nor any ERISA Affiliate of Thermo Electron has any contingent liability under Section 4204 of ERISA, (D) no circumstances exist that present a material risk that any such plan will go into reorganization, and (E) to the best of Thermo Electron’s Knowledge, the aggregate withdrawal liability of Thermo Electron and each ERISA Affiliate of Thermo Electron computed as if a complete withdrawal by Thermo Electron and any ERISA Affiliate of Thermo Electron had occurred under each such Thermo Electron Benefit Plan on the date hereof, would not reasonably be expected to result in a material liability to Thermo Electron. No Thermo Electron Benefit Plan subject to ERISA is a plan that has two or more contributing sponsors at least two of whom are not under common control, within the meaning of Section 4063 of ERISA.

      (vii) No Thermo Electron Benefit Plan provides health benefits (whether or not insured) with respect to employees or former employees of Thermo Electron or any of its Subsidiaries after retirement or other termination of service (other than coverage mandated by Applicable Laws or benefits, the full cost of which is borne by the employee or former employee).
      (viii) Neither the negotiation and execution of this Agreement nor the consummation of the transactions contemplated hereby will (either alone or upon the occurrence of any additional or subsequent events) constitute an event under any Thermo Electron Benefit Plan (for this purpose, Thermo Electron Benefit Plan (other than with respect to those Plans that are Thermo Electron Foreign Plans) shall be determined without regard to whether any plan, agreement, policy, understanding or arrangement is material despite the use of such qualifier in Section 3.1(i)(i) for purposes of the definition of Benefit Plan and Section 3.2(i)(i) for purposes of the definition of Thermo Electron Benefit Plan) that will or may result in any payment (whether of severance pay or otherwise), acceleration of payment, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any employee or former employee of Thermo Electron or any of its Subsidiaries or limit the ability to amend, terminate or receive a reversion of assets from any Thermo Electron Benefit Plan or related trust. There is no contract, agreement, plan or arrangement with an employee or former employee of Thermo Electron to which Thermo Electron or any of its Subsidiaries is a party as of the date of this Agreement that, individually or collectively and as a result of the transaction contemplated hereby (whether alone or upon the occurrence of any additional or subsequent events) would reasonably be expected to give rise to the payment of any amount that would not be deductible pursuant to Sections 280G or 162(m) of the Code.

        (O) Any Contract the termination or breach of which, or the failure to obtain consent in respect of which, would reasonably be expected to have a Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a whole.
      (ii) Schedule. Section 3.2(r)(ii) of the Thermo Electron Disclosure Schedule sets forth a list of all Thermo Electron Material Contracts as of the date hereof other than those listed as an exhibit to Thermo Electron’s most recent Form 10-K.
      (iii) No Breach. All Thermo Electron Material Contracts are valid and in full force and effect and enforceable in accordance with their respective terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws relating to or affecting the rights and remedies of creditors generally and to general principles of equity (regardless of whether considered in a proceeding in equity or at law), except to the extent that (A) they have previously expired in accordance with their terms or (B) the failure to be in full force and effect, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a whole. Neither Thermo Electron nor any of its Subsidiaries, nor, to Thermo Electron’s Knowledge, any counterparty to any Thermo Electron Material Contract, has violated any provision of, or committed or failed to perform any act which, with or without notice, lapse of time or both would constitute a default under the provisions of, any Thermo Electron Material Contract, except in each case for those violations and defaults which, individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect on Thermo Electron and its Subsidiaries, taken as a whole.
      (s) Real Property.

All of the improvements located on any Thermo Electron Owned Real Property or Thermo Electron Leased Real Property are in good condition and repair (subject to normal wear and tear) without any structural defects of any kind. Except as set forth in Section 3.2(s) of the Thermo Electron Disclosure Schedule, each material lease with respect to the Thermo Electron Leased Real Property is valid, unmodified and in full force and effect, and there are no material subleases with respect to the Thermo Electron Leased Real Property.

As of the date of this Agreement, neither Thermo Electron nor any of its Subsidiaries (a) has taken (or caused to be taken) any action or knows of any fact, agreement, plan or other circumstance that would reasonably be expected to prevent the Merger from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code or (b) knows of no reason why all approvals required for the consummation of the transactions contemplated by this Agreement should not be obtained on a timely basis.

Notwithstanding anything to the contrary contained in this Agreement, Fisher or Thermo Electron may adjourn or postpone the Fisher Stockholders’ Meeting or Thermo Electron Stockholders’ Meeting, as the case may be, to the extent necessary to ensure that any necessary supplement or amendment to the Joint Proxy Statement is provided to their respective stockholders, in advance of a vote on, in the case of Thermo Electron, the Stock Issuance and the Charter Amendment and, in the case of Fisher, the approval and adoption of this Agreement and the Merger, or, if, as of the time for which the Fisher Stockholders’ Meeting or Thermo Electron Stockholders’ Meeting, as the case may be, is originally scheduled, there are insufficient shares of Fisher Common Stock or Thermo Electron Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting. Each of Fisher and Thermo Electron shall ensure that the Fisher Stockholders’ Meeting and the Thermo Electron Stockholders’ Meeting, respectively, is called, noticed, convened, held and conducted, and that all proxies solicited in connection with the Fisher Stockholders’ Meeting or Thermo Electron Stockholders’ Meeting, as the case may be, are solicited in compliance with Applicable Laws, the rules of the NYSE and, in the case of Fisher, the Fisher Organizational Documents, and, in the case of Thermo Electron, the Thermo Electron Organizational Documents. Except with respect to matters as to which preliminary proxy materials would not be required to be filed with the

Subject to Applicable Laws relating to the exchange of information, Fisher and Thermo Electron shall have the right to review in advance, and to the extent reasonably practicable each will consult the other on, all the information relating to Fisher and its Subsidiaries or Thermo Electron and its Subsidiaries, as the case may be, that appears in any filing made with, or written materials submitted to, any Governmental Entity in connection with the Merger and the other transactions contemplated by this Agreement.
      (b) Each of Thermo Electron and Fisher shall keep the other reasonably apprised of the status of matters relating to the completion of the transactions contemplated hereby and work cooperatively in connection with obtaining all required approvals or consents of any Governmental Entity. In that regard, each party shall without limitation: (i) promptly notify the other of, and if in writing, furnish the other with copies of (or, in the case of oral communications, advise the other orally of) any communications from or with any Governmental Entity with respect to the Merger or any of the other transactions contemplated by this Agreement, (ii) permit the other to review and discuss in advance, and consider in good faith the views of the other in connection with, any proposed written (or any proposed oral) communication with any such Governmental Entity with respect to the Merger or any of the other transactions contemplated by this Agreement, (iii) not participate in any meeting or oral communication with any such Governmental Entity with respect to the Merger or any of the other transactions contemplated by this Agreement unless it consults with the other in advance and, to the extent permitted by such Governmental Entity, gives the other the opportunity to attend and participate thereat, (iv) furnish the other with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between it and any such Governmental Entity with respect to the Merger or any of the other transactions contemplated by this Agreement and the Merger, and (v) furnish the other with such necessary information and reasonable assistance as the other may reasonably request in connection with its preparation of necessary filings or submissions of information to any such Governmental Entity. Each of Thermo Electron and Fisher may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other under this Section 5.4 as “outside counsel only.” Such material and the information contained therein shall be given only to the outside legal counsel of the recipient and will not be disclosed by such outside counsel to employees, officers, or directors of the recipient unless express permission is obtained in advance from the source of the materials (Thermo Electron or Fisher, as the case may be) or its legal counsel.
      (c) In connection with and without limiting the foregoing, Thermo Electron and Fisher shall (i) take all action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to this Agreement or any of the transactions contemplated hereby and (ii) if any state takeover statute or similar statute or regulation becomes applicable to this Agreement or any of the transactions contemplated hereby, take all action necessary to ensure that such transactions may be consummated as promptly as practicable on the terms required by, or provided for, in this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger and the other transactions contemplated by this Agreement.
      (d) In connection with the filings referenced in Section 5.4(a)and (b), the parties shall cooperate with each other and use their respective reasonable best efforts to promptly prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, to obtain as promptly as practicable all permits, consents, approvals and authorizations of all Governmental Entities that are necessary or advisable to consummate the transactions contemplated by this Agreement (including the Merger), and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such third parties or Governmental Entities. Notwithstanding the foregoing, nothing contained herein shall be deemed to require Thermo Electron or Fisher to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of Governmental Entities, that would reasonably be expected to have a material adverse effect (measured on a

scale relative to Thermo Electron in the case of Thermo Electron and Fisher in the case of Fisher) on either Thermo Electron or Fisher, respectively.
      (e) Fisher and its Subsidiaries shall, upon reasonable notice, provide, and shall cause their respective officers, employees and representatives to provide, all cooperation reasonably requested by Thermo Electron in connection with (i) the repayment, repurchase, redemption, defeasance, modification, refinancing, or assumption, of all rights, duties and obligations, contingent or otherwise, of Fisher and its Subsidiaries in respect of the Fisher financings described in Section 5.4(e) of the Fisher Disclosure Schedule and (ii) the contemplated Thermo Electron financings identified in Section 5.4(e) of the Thermo Electron Disclosure Schedule; provided that, notwithstanding the foregoing, no request for cooperation or other assistance shall be required if it would unreasonably disrupt the business or operations of Fisher or any of its Subsidiaries.
      Section 5.5.     Indemnification and Insurance.
      (a) From and after the Effective Time, Thermo Electron will, and will cause the Surviving Corporation to, fulfill and honor in all respects the obligations of Fisher pursuant to any indemnification agreements between Fisher and its present or former directors, officers and employees in effect immediately prior to the Effective Time, subject to Applicable Laws. For at least six years after the Effective Time, Thermo Electron shall, and shall cause the Surviving Corporation to, indemnify and hold harmless the present and former officers and directors of Fisher and its Subsidiaries (the “Indemnified Parties”) for any costs, judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that such Person is or was an officer, director or employee of Fisher or any of its Subsidiaries in respect of acts or omissions occurring at or prior to the Effective Time (including those related to this Agreement and the transactions contemplated hereby), and shall advance expenses in respect thereof, in each case, to the fullest extent permitted by Applicable Laws.
      (b) For a period of six years after the Effective Time, the Surviving Corporation shall cause to be maintained in effect the current policies of directors’ and officers’ and fiduciary liability insurance maintained by Fisher with respect to claims arising from facts or events which occurred on or before the Effective Time (including those related to this Agreement and the transactions contemplated hereby); provided, that the Surviving Corporation may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are no less advantageous to former officers and directors of Fisher only with respect to claims arising from facts or events which occurred at or before the Effective Time; and provided, further, that if the aggregate annual premiums for such policies at any time during such period will exceed 250% of the per annum premium rate paid by Fisher and its Subsidiaries as of the date hereof for such policies, then Thermo Electron shall be required to provide as much coverage as is then available at such annual premium.
      (c) Notwithstanding anything herein to the contrary and to the maximum extent permitted by Applicable Laws, if any claim, action, suit, proceeding or investigation is made or brought against any Indemnified Party on or prior to the sixth anniversary of the Effective Time, the provisions of this Section 5.5 shall continue in effect until the final disposition of such claim, action, suit, proceeding or investigation.
      (d) If Thermo Electron, the Surviving Corporation or any of their respective successors or assigns (i) shall consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties or assets to any Person, then, in each case, Thermo Electron shall take such action as may be necessary so that such Person shall assume all of the applicable obligations set forth in this Section 5.5.
      (e) The provisions of this Section 5.5 are (i) intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and representatives and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise.
      Section 5.6.     Fees and Expenses. Except as set forth in this Section 5.6 and in Section 7.2, all fees and expenses incurred in connection with the Merger, this Agreement and the transactions contemplated by

A-47


Table of Contents

this Agreement shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated, except that each of Fisher and Thermo Electron shall bear and pay one-half of the costs and expenses incurred by Thermo Electron, Merger Sub or Fisher (other than attorneys’ fees, accountants’ fees and related expenses) in connection with (i) the filing, printing and mailing of the Form S-4 (including financial statements and exhibits), the Joint Proxy Statement (including SEC filing fees) and any preliminary materials related thereto and (ii) the filings of the premerger notification and report forms under the HSR Act and any applicable antitrust, competition or similar laws of any foreign jurisdiction (including filing fees).
      Section 5.7.     Public Announcements. Neither Fisher nor Thermo Electron shall, and neither Fisher nor Thermo Electron shall permit any of their respective Subsidiaries to, issue or cause the publication of any press release or other public announcement with respect to, or otherwise make any public statement concerning, the transactions contemplated by this Agreement without the prior consent (which consent shall not be unreasonably withheld) of Thermo Electron, in the case of a proposed announcement or statement by Fisher, or Fisher, in the case of a proposed announcement or statement by Thermo Electron; provided, however, that either party may, without the prior consent of the other party (but after prior consultation with the other party to the extent practicable under the circumstances) issue or cause the publication of any press release or other public announcement to the extent required by law or by the rules and regulations of the NYSE.
      Section 5.8.     Listing. Thermo Electron shall use reasonable best efforts to cause the Thermo Electron Common Stock issuable under Article II, and those shares of Thermo Electron Common Stock required to be reserved for issuance in connection with the Merger, to be authorized for listing on the NYSE, upon official notice of issuance.
      Section 5.9.     Tax-Free Reorganization Treatment. Thermo Electron and Fisher hereby adopt this Agreement as a plan of reorganization within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a). Thermo Electron and Fisher intend that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Code, and each shall, and shall cause their respective Subsidiaries to, use its reasonable best efforts to cause the Merger to so qualify. Neither Thermo Electron, Merger Sub nor Fisher shall take any action, cause or permit any action to be taken, or fail to take any action, that would reasonably be expected to cause the Merger to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code.
      Section 5.10.     Conveyance Taxes. Fisher and Thermo Electron shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp taxes, any transfer, recording, registration and other fees or any similar taxes which become payable in connection with the transactions contemplated by this Agreement that are required or permitted to be filed on or before the Effective Time.
      Section 5.11.     Equity Awards and Employee Benefits.
      (a) Equity Awards. (i) Fisher Options. At the Effective Time, each then outstanding Fisher Option, whether or not exercisable at the Effective Time, will be assumed by Thermo Electron. Subject to, and in accordance with, the terms of the applicable Fisher Stock Plan and option award agreement, each Fisher Option so assumed by Thermo Electron under this Agreement will otherwise continue to have, and be subject to, the same terms and conditions set forth in the applicable Fisher Option (including any applicable option award agreement or other document evidencing such Fisher Option) immediately prior to the Effective Time (including any vesting or forfeiture provisions or repurchase rights, but taking into account any acceleration of Fisher Options pursuant to any Fisher Benefit Plan or applicable option award agreement), except that (A) each Fisher Option, when exercisable, will be exercisable for that number of whole shares of Thermo Electron Common Stock equal to the product of the number of shares of Fisher Common Stock that were subject to such Fisher Option immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of Thermo Electron Common Stock and (B) the per share exercise price for the shares of Thermo Electron Common Stock issuable upon exercise of such assumed Fisher Option will be equal to the quotient determined by dividing the exercise price per share of Fisher Common Stock of such Fisher Option by the Exchange Ratio, rounded up to the nearest whole cent.

A-48

      (ii) Fisher Stock Unit Awards. At the Effective Time, each Fisher Stock Unit Award then outstanding shall be assumed by Thermo Electron. Subject to, and in accordance with, the terms of the applicable Fisher Stock Plan or Fisher Deferred Compensation Plan and any applicable award or other agreement, each Fisher Stock Unit Award shall be converted into the right to receive the number of shares of Thermo Electron Common Stock (or an amount in respect thereof for cash settled Fisher Stock Unit Awards) equal to the number of shares of Fisher Common Stock subject to the Fisher Stock Unit Award, multiplied by the Exchange Ratio (rounded down to the nearest whole number of shares of Thermo Electron Common Stock). Each Fisher Stock Unit Award shall have the same terms and conditions as were in effect immediately prior to the Effective Time, except that the performance conditions applicable to the vesting of the assumed Fisher Stock Unit Awards shall be deemed to have been satisfied effective as of the Closing Date, and such Fisher Stock Unit Awards (other than those granted under the Fisher 2005 Equity and Incentive Plan) that are evidenced by a Performance Based Restricted Stock Unit Purchase Agreement and which become vested and payable in accordance with their current terms upon a change in control transaction (for this purpose taking into account Section 5.11(e) hereof) (the holders of which and the related number of units are identified on a list which Fisher has delivered to Thermo Electron prior to the date hereof), shall instead vest and be settled in three equal increments on the first three anniversaries of the original grant date of the Fisher Stock Unit Award, subject to the holder’s continued employment with Thermo Electron or the Surviving Corporation or their Subsidiaries as of each such vesting date, unless, following the Closing Date, the holder of the Fisher Stock Unit Award is terminated prior to the full vesting of the Fisher Stock Unit Award either without Cause or for Good Reason (as each such term is defined in Fisher’s 2005 Equity and Incentive Plan), in which case the Fisher Stock Unit Award will vest immediately upon such termination of employment. Fisher Stock Unit Awards described in this Section 5.11(a)(ii) that vest upon a termination of employment as described in the previous sentence shall be settled upon the earliest date following the applicable vesting date which will not cause an imposition of any additional tax under Section 409A of the Code.
      (iii) Fisher and Thermo Electron agree that prior to the Effective Time, Fisher shall, and shall be permitted under this Agreement to, take all corporate action necessary, including, but not limited to, amending any Fisher Option, Fisher Stock Unit Award or Fisher equity award agreement evidencing such award, or Fisher Stock Plan or Fisher Deferred Compensation Plan, (A) to effectuate the provisions of Section 5.11(a)(i) and Section 5.11(a)(ii) and (B) to the extent applicable, to preclude any automatic or formulaic grant of options, restricted shares or other awards thereunder on or after the date hereof other than pursuant to the Fisher Purchase Plan as in effect on the date hereof. From and after the Effective Time, all references to Fisher (other than any references relating to a “change in control” of Fisher) in each Fisher Stock Plan, Fisher Deferred Compensation Plan and in each agreement evidencing any Fisher Options or Fisher Stock Unit Awards shall be deemed to refer to Thermo Electron, unless Thermo Electron determines otherwise. As soon as reasonably practicable, but in no event later than ten business days following the Effective Time, Thermo Electron will (A) issue to each holder of an assumed Fisher Option or Fisher Stock Unit Award a document evidencing the foregoing assumption of such Fisher Option or Fisher Stock Unit Award by Thermo Electron, (B) issue appropriate notices setting forth such holders’ rights pursuant to the assumed Fisher Options or Fisher Stock Unit Awards, and (C) issue appropriate notices to each holder of an assumed Fisher Option or Fisher Stock Unit Award setting forth the effect of the Merger on the Fisher Options or Fisher Stock Unit Awards. Prior to the Effective Time, Thermo Electron shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Thermo Electron Common Stock for delivery in connection with the exercise of the converted Fisher Options and Fisher Stock Unit Awards. The parties shall use their reasonable best efforts to ensure that the conversion of any Fisher Options which are intended to be “incentive stock options” (as defined in Section 422 of the Code) provided for in Section 5.11(a)(i) shall be effected in a manner consistent with Section 424(a) of the Code.
      (iv) Within one business day of the Closing Date, Thermo Electron shall register the shares of Thermo Electron Common Stock subject to Fisher Options and Fisher Stock Unit Awards by filing an effective registration statement on Form S-8 (or any successor form) or another appropriate form, and Thermo Electron shall maintain the effectiveness of such registration statement or registration statements with respect thereto for so long as such awards remain outstanding. Following the Closing Date, Thermo Electron may grant equity awards under the Fisher Stock Plans, to the extent shares are available for grant under any such

A-49

plan, in accordance with the mergers and acquisitions exemption to the equity compensation plan shareholder approval requirement under the NYSE rules.
      (v) Notwithstanding the foregoing, Thermo Electron shall not be required to take any of the actions contemplated by this Section 5.11(a) if, and to the extent that, such action does not comply with the Applicable Law of any foreign jurisdiction.
      (b) Fisher shall terminate the Fisher Purchase Plan at least one full payroll period prior to the Effective Time. To the extent any offering period under the Fisher Purchase Plan is in progress prior to such termination, Fisher shall ensure that such offering period ends immediately prior to such termination, and that each participant’s accumulated contributions for such offering period are applied towards the purchase of Fisher Common Stock immediately prior to such termination unless the participant has previously withdrawn from such offering period in accordance with the terms of such plan.
      (c) This Section 5.11(c) shall apply to each employee of Fisher or its Subsidiaries as of immediately prior to the Effective Time other than Represented Employees (as defined in Section 5.12) (the “Fisher Employees”). Following the Closing Date, and for two years thereafter, but in no event later than such time as a Fisher Employee ceases to be employed by or provide services to Thermo Electron or the Surviving Corporation or their Subsidiaries following the Effective Time, Thermo Electron shall provide, or cause to be provided, the Fisher Employees, benefits and compensation (other than stock options or other equity-based incentive plans, programs, agreements or arrangements) that in the aggregate are substantially no less favorable than the benefits provided, in the aggregate, to such individuals by Fisher and its Subsidiaries; it being understood that the Fisher Employees may commence participating in the Thermo Electron Benefit Plans on different dates following the Closing Date with respect to different Thermo Electron Benefit Plans. Thermo Electron shall give Fisher Employees full credit for purposes of eligibility, vesting, determination of the level of benefits and benefit accrual under any employee benefit plans or arrangements maintained by Thermo Electron or any Subsidiary for such Fisher Employees’ service with Fisher and its Subsidiaries (and service with any predecessor, to the extent recognized by Fisher or its Subsidiaries) prior to the Closing Date, except to the extent that such crediting would result in duplication of benefits and provided that no prior service credit shall be recognized for purposes of (i) benefit accrual, level of pay credits and/or grandfathering under any defined benefit plan or (ii) post-retirement welfare benefits. Thermo Electron shall (i) waive all limitations as to preexisting conditions exclusions and waiting periods with respect to participation and coverage requirements applicable to the Fisher Employees under any welfare benefit plans that such employees may be eligible to participate in after the Effective Time, other than limitations or waiting periods that are already in effect with respect to such employees and that have not been satisfied as of the Effective Time under any welfare plan maintained for the Fisher Employees immediately prior to the Closing Date, and (ii) provide each Fisher Employee with credit for any co-payments and deductibles paid under any Fisher Benefit Plan that provides healthcare benefits in the plan year in effect as of the Closing Date in satisfying any applicable deductible or out-of-pocket requirements under any healthcare plans of Thermo Electron or the Surviving Corporation that such employees are eligible to participate in after the Effective Time to the same extent that such expenses were recognized under the comparable Fisher Benefit Plan.
      (d) Notwithstanding anything in this Agreement to the contrary, no provision of this Agreement shall be deemed to (i) guarantee employment for any period of time for, or preclude the ability of either party to terminate, any Fisher Employee for any reason or (ii) subject to the limitations and requirements specifically set forth in this Section 5.11, require either party to continue any Thermo Electron Benefit Plan or Fisher Benefit Plan or prevent the amendment, modification or termination thereof after the Effective Time.
      (e) Without limiting the generality of the foregoing, as of the Effective Time, Thermo Electron shall cause the Surviving Corporation and its Subsidiaries to honor in accordance with their terms all employment, change in control, severance and other compensation agreements and arrangements existing prior to the execution of this Agreement which are between Fisher or any Subsidiary and any director, officer or employee thereof and set forth in Section 5.11(e) of the Fisher Disclosure Schedule (each a “Fisher Executive Agreement”); provided, that, nothing herein shall prevent Thermo Electron from amending any such agreement or plan in accordance with its terms, including such amendments as may be necessary to avoid the

imposition of a tax under Section 409A of the Code. Fisher and Thermo Electron hereby agree that the occurrence of the Closing shall constitute a “Change in Control” for purposes of any Fisher Executive Agreement and all Fisher Benefit Plans and related trusts set forth in Section 5.11(e) of the Fisher Disclosure Schedule.
      (f) Fisher shall be entitled to pay or provide for cash bonus payments in an aggregate amount not to exceed the amount set forth in Section 5.11(f) of the Fisher Disclosure Schedule, to such individuals, in such amounts and upon such terms and conditions as Fisher may determine consistent with such schedule.
      (g) As soon as practicable following the date hereof (but in any event within 30 days hereof), the Board of Directors of Thermo Electron shall, in consultation with Fisher and with Fisher’s approval (which shall not be unreasonably withheld), establish a long-term incentive compensation program for Thermo Electron senior management, which awards shall provide each such employee with unvested long-term incentive compensation that is comparable in aggregate value to the currently unvested (but with accelerated vesting upon the consummation of the transactions contemplated by this Agreement) equity-based and other long-term incentive compensation that is now held by such employee.
      (h) Following the date hereof, but in no event later that 30 days following the date hereof, Fisher shall take action with respect to the plan identified in Section 5.11(h) of the Fisher Disclosure Schedule in the manner set forth in such Schedule.
      Section 5.12.     Honoring of Collective Bargaining Agreements; Represented Employees. With respect to any continuing employee whose terms and conditions of employment are governed by any of the collective bargaining agreements listed on Section 3.1(h)(ii) of the Fisher Disclosure Schedule (each a “Represented Employee”), Thermo Electron agrees to honor or cause to be honored the collective bargaining agreements listed on Section 3.1(h)(ii) of the Fisher Disclosure Schedule as of the Closing Date and to continue all terms and conditions of employment applicable to such Represented Employees under their respective collective bargaining agreements through the expiration, modification or termination of such agreements in conformity with Applicable Law.
      Section 5.13.     Affiliates. Fisher shall use its reasonable efforts to cause each Person who is, in Fisher’s reasonable judgment, an “affiliate” of Fisher within the meaning of Rule 145 promulgated under the Securities Act (“Rule 145 Affiliates”) to deliver to Thermo Electron, as soon as reasonably practicable and in any event prior to the meeting of Fisher stockholders to be held pursuant to Section 5.1(b), a written agreement substantially in the form attached as Exhibit 5.13. Thermo Electron shall be entitled to place appropriate legends (reasonably acceptable to Fisher) on the certificates evidencing any shares of Thermo Electron Common Stock to be received by Rule 145 Affiliates in the Merger reflecting the restrictions set forth in Rule 145 promulgated under the Securities Act and to issue appropriate stop transfer instructions to the transfer agent for Thermo Electron Common Stock (provided, that such legends or stop transfer instructions shall be removed, one year after the Effective Time, upon the request of any holder of shares of Thermo Electron Common Stock issued in the Merger if such holder is not then a Rule 145 Affiliate).
      Section 5.14.     Notification of Certain Matters. Thermo Electron shall give prompt notice to Fisher and Fisher shall give prompt notice to Thermo Electron, as the case may be, of the occurrence, or failure to occur, of any event, which occurrence or failure to occur would reasonably be expected to cause (a)(i) any representation or warranty of such party contained in this Agreement that is qualified as to “materiality” or “Material Adverse Effect” to be untrue or inaccurate in any respect or (ii) any other representation or warranty of such party contained in this Agreement that is not qualified as to “materiality” or “Material Adverse Effect” to be untrue or inaccurate in any material respect, in each case at any time from and after the date of this Agreement until the Effective Time, or (b) any material failure of Thermo Electron and the Merger Sub or Fisher, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it under this Agreement. In addition, Thermo Electron shall give prompt notice to Fisher and Fisher shall give prompt notice to Thermo Electron, as the case may be, of any change or event having, or which would reasonably be expected to have, a Material Adverse Effect on such party and its Subsidiaries, taken as a whole, or which would reasonably be expected to result in the failure of any of the conditions set forth in Article VI to be satisfied. Notwithstanding the above, the delivery of any notice

pursuant to this Section 5.14 will not limit or otherwise affect the remedies available hereunder to the party receiving such notice or the conditions to such party’s obligation to consummate the Merger.
      Section 5.15.     Section 16 Matters. Prior to the Effective Time, each of Thermo Electron and Fisher shall use their reasonable best efforts to take all such steps as may be required (to the extent permitted under Applicable Laws) to cause any dispositions of Fisher Common Stock (including derivative securities) or acquisitions of Thermo Electron Common Stock (including derivative securities with respect to Thermo Electron Common Stock) resulting from the transactions contemplated by this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Fisher to be exempt under Rule 16b-3 promulgated under the Exchange Act.
      Section 5.16.     State Takeover Laws. Prior to the Effective Time, neither Fisher nor Thermo Electron shall take any action to render inapplicable, or to exempt any third Person from, any state takeover law or state law that purports to limit or restrict business combinations or the ability to acquire or vote shares of capital stock unless (i) required to do so by order of a court of competent jurisdiction or (ii) Thermo Electron’s or Fisher’s Board of Directors, as the case may be, has concluded in good faith, after consultation with its outside legal counsel, that the failure to take such action is reasonably likely to result in a breach of its Board of Directors’ fiduciary obligations to their stockholders, respectively, under Applicable Laws.
      Section 5.17.     Reservation of Thermo Electron Common Stock.

Board of Directors
Thermo Electron Corporation
81 Wyman Street
Waltham, MA 02451
Members of the Board:
      We understand that Thermo Electron Corporation (the “Company” or “Thermo”) intends to enter into a transaction with Fisher Scientific International Inc. (“Fisher”), pursuant to which, among other things, a wholly owned subsidiary of Thermo (“MergerCo”) will merge with and into Fisher with Fisher surviving the merger (the “Proposed Transaction”). We further understand that, upon the effectiveness of the merger, each share of common stock of Fisher (“Fisher Common Stock”) then issued and outstanding (other than shares of Fisher Common Stock then owned by Thermo, MergerCo or Fisher) will be converted into the right to receive 2.000 shares (the “Exchange Ratio”) of common stock of Thermo (“Company Common Stock”). The terms and conditions of the Proposed Transaction are set forth in more detail in the Agreement and Plan of Merger, dated as of May 7, 2006, among Thermo, Fisher and MergerCo (the “Agreement”).
      We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company of the Exchange Ratio to be paid by the Company in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company’s underlying business decision to proceed with or effect the Proposed Transaction.
      In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the Proposed Transaction (including with respect to governance of the combined company), (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and the Company’s Quarterly Report on Form 10-Q for the quarter ended April 1, 2006, (3) publicly available information concerning Fisher that we believe to be relevant to our analysis, including Fisher’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 and Fisher’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2006, (4) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including financial estimates and forecasts for the Company prepared by the Company’s management, (5) financial and operating information with respect to the business, operations and prospects of Fisher furnished to us by Fisher, including financial estimates and forecasts for Fisher prepared by Fisher’s management, (6) the trading histories of Company Common Stock and Fisher Common Stock from May 6, 2005 to May 5, 2006 and a comparison of those trading histories with each other and with those of other companies and indices that we deemed relevant, (7) a comparison of the historical financial results and present financial condition of the Company and Fisher with each other and with those of other companies that we deemed relevant, (8) published estimates of independent research analysts with respect to ratings and future price targets of Company Common Stock and Fisher Common Stock, (9) the relative contributions of the Company and Fisher to the historical and future financial condition and performance of the combined company on a pro forma basis, (10) the potential pro forma impact of the Proposed Transaction on the future financial condition and performance of the Company, including estimated cost savings, operating synergies and other strategic benefits that the managements of the Company and Fisher currently anticipate will result from a combination of the businesses of the Company and Fisher (the “Estimated Synergies”) and the anticipated impact of the Proposed Transaction on the Company’s pro forma adjusted earnings per share, and (11) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other transactions that we deemed relevant. In

addition, we have had discussions with the managements of the Company and Fisher concerning their respective businesses, operations, assets, liabilities, financial conditions and prospects and have undertaken such other studies, analyses and investigations as we deemed appropriate.
      In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of managements of the Company and Fisher that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to forecasts and estimates prepared by the Company’s management and Fisher’s management, upon advice of the Company we have assumed that these forecasts and estimates have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the managements of the Company and Fisher as to the future financial performance of the Company and Fisher and that the Company and Fisher will perform substantially in accordance with these forecasts and estimates. Upon the advice of the Company and Fisher, we also have assumed that the Estimated Synergies will be realized substantially in accordance with such estimates. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and Fisher and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company or Fisher. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter.
      Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the Exchange Ratio to be paid by the Company in the Proposed Transaction is fair to the Company.
      We have acted as financial advisor to the Company in connection with the Proposed Transaction and will receive a fee for our services, a portion of which is payable upon delivery of this opinion and the remainder of which is contingent upon the consummation of the Proposed Transaction. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. We have also provided a $1.5 billion 364-day credit facility to be used by the Company for the potential refinancing of certain of Fisher’s and the Company’s indebtedness in connection with the Proposed Transaction, for which we expect to receive customary fees. We also have performed various investment banking services for the Company in the past and expect to perform various investment banking services for the Company in the future and have received, and expect to receive, customary fees for such services. In the ordinary course of our business, we actively trade in the debt and equity securities of the Company and Fisher for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities.
      This opinion is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the Proposed Transaction. This opinion is not intended to be and does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Proposed Transaction.
  Very truly yours,

Ladies and Gentlemen:
You have requested our opinion as to the fairness from a financial point of view to the holders of the outstanding shares of common stock, par value $0.01 per share (the “Shares”), of Fisher Scientific International Inc. (the “Company”) of the exchange ratio of 2.00 shares of common stock, par value $1.00 per share (“Thermo Electron Common Stock”), of Thermo Electron Corporation (“Thermo Electron”) to be received for each Share (the “Exchange Ratio”) pursuant to the Agreement and Plan of Merger, dated as of May 7, 2006 (the “Agreement”), among Thermo Electron, Thermo Merger Corporation, a direct wholly owned subsidiary of Thermo Electron (“Merger Sub”), and the Company.
Goldman, Sachs & Co. and its affiliates, as part of their investment banking business, are continually engaged in performing financial analyses with respect to businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and other transactions as well as for estate, corporate and other purposes. We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the transaction contemplated by the Agreement (the “Transaction”). We expect to receive fees for our services in connection with the Transaction, the principal portion of which fees are contingent upon the consummation of the Transaction, and the Company has agreed to reimburse our expenses and indemnify us against certain liabilities arising out of our engagement. In addition, we currently are providing and have provided certain investment banking services to the Company from time to time, including having acted as a lead manager in connection with the offering of 2.50% Convertible Senior Notes due October 2023 (aggregate principal amount $250,000,000) in July 2003; financial advisor with respect to the Company’s acquisition of Dharmacon Inc. in February 2004; a lead manager in connection with the offering of 3.25% Convertible Senior Subordinated Notes due March 1, 2024 (aggregate principal amount $300,000,000) in March 2004; financial advisor with respect to the Company’s acquisition of Apogent Technologies (“Apogent”) in March 2004; dealer manager for the exchange offers related to indebtedness of Apogent (aggregate principal amount $645,000,000) in May 2004; and a lead manager in connection with the offering of Senior Subordinated Notes due 2014 (aggregate principal amount $300,000,000) in July 2004. Our commercial bank affiliate is a lender under bank loans of the Company. We also may provide investment banking and other services to the Company and Thermo Electron in the future. In connection with the above-described investment banking services we have received, and may receive in the future, compensation.
Goldman, Sachs & Co. is a full service securities firm engaged, either directly or through its affiliates, in securities trading, investment management, financial planning and benefits counseling, risk management, hedging, financing and brokerage activities for both companies and individuals. In the ordinary course of these activities, Goldman, Sachs & Co. and its affiliates may provide such services to the Company and Thermo Electron and their respective affiliates, may actively trade the debt and equity securities (or related derivative securities) of the Company and Thermo Electron for their own account and for the accounts of their customers and may at any time hold long and short positions of such securities.
In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company and Thermo Electron for the five years ended December 31, 2005; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and Thermo Electron; certain other communications from the Company and Thermo Electron to

their respective stockholders; certain internal financial analyses and forecasts for Thermo Electron prepared by its management; certain internal financial analyses and forecasts for Thermo Electron prepared by its management, reviewed and revised by the management of the Company, and certain internal financial analyses and forecasts for the Company prepared by its management (the “Forecasts”); and certain cost savings and operating synergies projected by the respective managements of the Company and Thermo Electron to result from the Transaction (the “Synergies”). We also have held discussions with members of the senior managements of the Company and Thermo Electron regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of their respective companies. In addition, we have reviewed the reported price and trading activity for the Shares and Thermo Electron Common Stock, compared certain financial and stock market information for the Company and Thermo Electron with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the healthcare industry specifically and in other industries generally and performed such other studies and analyses, and considered such other factors, as we considered appropriate.
We have relied upon the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us and have assumed such accuracy and completeness for purposes of rendering this opinion. In that regard, we have assumed with your consent that the Forecasts and the Synergies have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the Company and Thermo Electron, as the case may be. In addition, we have not made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or off-balance-sheet assets and liabilities) of the Company or Thermo Electron or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal.
Our opinion does not address the underlying business decision of the Company to engage in the Transaction, nor are we expressing any opinion as to the prices at which shares of Thermo Electron Common Stock will trade at any time. We also have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction contemplated by the Agreement will be obtained without any adverse effect on the Company or Thermo Electron or on the expected benefits of the Transaction in any way meaningful to our analysis. 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. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Shares should vote with respect to such Transaction.
Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio pursuant to the Agreement is fair from a financial point of view to the holders of Shares.
Very truly yours,
/s/ Goldman, Sachs & Co.

LAZARD LETTERHEAD
May 7, 2006
The Board of Directors
Fisher Scientific International Inc.
1 Liberty Lane
Hampton, New Hampshire 03842
Dear Members of the Board:
      We understand that Thermo Electron Corporation, a Delaware corporation (“Thermo Electron”), Trumpet Merger Corporation, a Delaware corporation and a wholly owned subsidiary of Thermo Electron (“Merger Sub”), and Fisher Scientific International Inc., a Delaware corporation (“Fisher Scientific”), propose to enter into an Agreement and Plan of Merger to be dated on or about the date hereof (the “Merger Agreement”), pursuant to which, among other things, Merger Sub will be merged with and into Fisher Scientific (the “Merger”), with Fisher Scientific continuing as the surviving corporation in the Merger and a wholly owned subsidiary of Thermo Electron. Pursuant to the Merger, each issued and outstanding share of common stock, par value $0.01 per share, of Fisher Scientific (“Fisher Scientific Common Stock”), other than any shares of Fisher Scientific Common Stock owned by Thermo Electron, Merger Sub or Fisher Scientific immediately prior to the effective time of the Merger (collectively, the “Excluded Shares”), shall be automatically converted into and become the right to receive 2.00 fully paid and nonassessable shares (the “Exchange Ratio”) of common stock, par value $1.00 per share, of Thermo Electron (“Thermo Electron Common Stock”). Upon consummation of the Merger, the Convertible Subordinated Debentures of Fisher Scientific shall become convertible into Thermo Electron Common Stock at a conversion ratio equal to the conversion ratio in effect immediately prior to the effective time of the Merger multiplied by the Exchange Ratio. The terms and conditions of the Merger are more fully set forth in the Merger Agreement.
      You have requested our opinion, as of the date hereof, as to the fairness, from a financial point of view, to the holders of shares of Fisher Scientific Common Stock (other than the holders of the Excluded Shares) of the Exchange Ratio pursuant to the Merger. In connection with this opinion, we have:
     
(i)
  Reviewed the financial terms and conditions of the latest draft of the Merger Agreement;
 
(ii)
  Analyzed certain historical business and financial information relating to Fisher Scientific and Thermo Electron;
 
(iii)
  Reviewed various financial forecasts and other data provided to us by Fisher Scientific and Thermo Electron relating to their respective businesses;
 
(iv)
  Reviewed the synergistic savings and benefits and the timing of their occurrence as projected by Fisher Scientific and Thermo Electron to be realized by the combined company following the Merger;
 
(v)
  Held discussions with members of the senior managements of Fisher Scientific and Thermo Electron with respect to the businesses and prospects of Fisher Scientific and Thermo Electron, respectively, the strategic objectives of each, and synergistic savings and benefits projected by Fisher Scientific and Thermo Electron to be realized by the combined company following the Merger;

D-1


Table of Contents

     
(vi)
  Reviewed public information with respect to certain other companies in lines of business we believe to be generally comparable to those of Fisher Scientific and Thermo Electron;
 
(vii)
  Reviewed the financial terms of certain business combinations involving companies in lines of business we believe to be generally comparable to those of Fisher Scientific and Thermo Electron;
 
(viii)
  Reviewed the historical stock prices and trading volumes of Fisher Scientific Common Stock and Thermo Electron Common Stock; and
 
(ix)
  Conducted such other financial studies, analyses and investigations as we deemed appropriate.
      We have relied upon the accuracy and completeness of the foregoing information. We have not assumed any responsibility for any independent verification of such information or any independent valuation or appraisal of any of the assets or liabilities of Fisher Scientific or Thermo Electron, or concerning the solvency or fair value of Fisher Scientific or Thermo Electron. With respect to financial forecasts, including the synergistic savings and benefits projected by Fisher Scientific and Thermo Electron to be realized following the Merger and the timing of their occurrence, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of management of Fisher Scientific and Thermo Electron as to the future financial performance of Fisher Scientific and Thermo Electron, respectively, and of both Fisher Scientific and Thermo Electron with respect to the combined company. We assume no responsibility for and express no view as to such financial forecasts and estimates or the assumptions on which they are based.
      Further, 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. We assume no responsibility for updating or revising our opinion based on circumstances or events occurring after the date hereof.
      In rendering our opinion, we have assumed that the Merger will be consummated on the terms described in the latest draft of the Merger Agreement reviewed by us, without any waiver or modification of any material terms or conditions, that obtaining the necessary regulatory approvals for the Merger will not have an adverse effect on Fisher Scientific, Thermo Electron or the combined company, and that the synergistic savings and benefits of the Merger projected by Fisher Scientific and Thermo Electron will be substantially realized both in scope and timing. In addition, we have assumed that the representations and warranties of Fisher Scientific and Thermo Electron contained in the draft Merger Agreement are true and complete and that the Merger will be accounted for as a tax-free “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code. We do not express any opinion as to any tax or other consequences that might result from the Merger, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that Fisher Scientific has obtained such advice as it deemed necessary from qualified professionals.
      We do not express any opinion as to the price at which shares of Fisher Scientific Common Stock or shares of Thermo Electron Common Stock may trade subsequent to the date hereof.
      Lazard Frères & Co. llc (“Lazard”) is acting as investment banker to Fisher Scientific in connection with the Merger and will receive a fee for our services, a substantial portion of which is contingent upon the consummation of the Merger. We have in the past provided investment banking services to Fisher Scientific, for which we have received customary fees. In addition, in the ordinary course of their respective businesses, affiliates of Lazard and LFCM Holdings LLC (an entity indirectly held in large part by managing directors of Lazard) may actively trade securities of Fisher Scientific or Thermo Electron for their own accounts and for the accounts of their customers and, accordingly, may at any time hold a long or short position in such securities.
      Our engagement and the opinion expressed herein are for the benefit of the Board of Directors of Fisher Scientific and are not on behalf of, and are not intended to confer rights or remedies upon, Thermo Electron, any stockholder of Fisher Scientific or Thermo Electron or any other person. Our opinion does not address the merits of the underlying decision by Fisher Scientific to engage in the Merger or the relative merits of the Merger as compared to other business strategies or transactions that might be available to Fisher Scientific.

      Based on and subject to the foregoing, we are of the opinion that, as of the date hereof, the Exchange Ratio pursuant to the Merger is fair from a financial point of view to the holders of Fisher Scientific Common Stock (other than the holders of Excluded Shares).

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS; UNDERTAKINGS
Item 20. Indemnification of Directors and Officers
      The following summary is qualified in its entirety by reference to the complete copy of the General Corporation Law of the State of Delaware, or the DGCL, and Thermo’s Amended and Restated Certificate of Incorporation, as amended.
      Section 145 of the DGCL generally provides that all directors and officers (as well as other employees and individuals) may be indemnified against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with certain specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation, or a derivative action), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard of care is applicable in the case of derivative actions, except that indemnification extends only to expenses (including attorneys’ fees) incurred in connection with defense or settlement of an action, and the DGCL requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. Section 145 of the DGCL also provides that the rights conferred thereby are not exclusive of any other right to which any person may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, and permits a corporation to advance expenses to or on behalf of a person entitled to be indemnified upon receipt of an undertaking to repay the amounts advanced if it is determined that the person is not entitled to be indemnified.
      As permitted by Section 102(b)(7) of the DGCL, the Amended and Restated Certificate of Incorporation of Thermo, as amended, provides that no director shall be personally liable to Thermo or its stockholders for monetary damages for breach of fiduciary duty as a director other than (i) for any breach of the director’s duty of loyalty to Thermo and its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, and (iv) for any transaction from which the director derived an improper personal benefit. Thermo also has indemnification agreements with its directors and officers that provide for the maximum indemnification allowed by law.
      Thermo has an insurance policy which insures the directors and officers of Thermo and its subsidiaries against certain liabilities which might be incurred in connection with the performance of their duties.

Item 22.      Undertakings
      The undersigned registrant hereby undertakes:
      (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the “Securities Act”); (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement (notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement); and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
      (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
      (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
      (4) That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
      (5) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.
      (6) That every prospectus (i) that is filed pursuant to paragraph (5) above, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to this registration statement and will not be used until such amendment has become effective, and that for the purpose of determining liabilities under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
      (7) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the

incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
      (8) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.
      (9) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
