                                [CRC LETTERHEAD]



                                January __, 1995


        Dear Fellow Shareholders:

             Your are cordially invited to attend a Special Meeting of
        the Shareholders of Coleman Research Corporation ("CRC") to vote
        on the proposed acquisition of CRC by Thermo Electron Corporation
        ("Thermo") through the merger (the "Merger") of CRC with a wholly
        owned subsidiary of Thermo.  Upon consummation of the Merger, you
        will receive in exchange for each share of CRC common stock that
        you own on the effective date of the Merger .1905695 shares of
        Thermo common stock.  Based on the closing price of the Thermo
        common stock on the New York Stock Exchange on December 15, 1994,
        $43.00, the Merger is intended to provide $8.19 in value of
        Thermo common stock in exchange for each share of CRC common
        stock.  However, the closing price of the Thermo common stock on
        the effective date of the Merger may be more or less than $43.00.
        Ten percent of the shares of Thermo common stock you would be
        entitled to receive in the Merger will be held in escrow to
        provide indemnification to Thermo against damages incurred as a
        result of any misrepresentations, breaches of warranties and
        breaches of covenants in connection with the Merger.  See "THE
        MERGER -- Indemnification of Thermo; Escrow."

             At the Special Meeting, shareholders will be asked to
        approve and adopt the Agreement and Plan of Merger.  In addition,
        shareholders will be asked to approve the Amended and Restated
        Articles of Incorporation of CRC, which deletes a current
        provision in CRC's Articles of Incorporation, as amended, that
        limits stock ownership to employees of CRC, and to approve the
        assignment by CRC of its 49% interest in Coleman Laboratories,
        Ltd., a limited partnership ("Coleman L.P."), to entities related
        to Thomas J. Coleman or members of his family and the termination
        of CRC's relationship with Dr. Mohammed Katoot and MK Industries
        Inc. ("MKI") by assigning and selling to Coleman L.P. CRC's
        rights under certain agreements with Dr. Katoot and MKI and
        certain equipment currently used by MKI (the "Coleman
        Laboratories Transaction").

             The Special Meeting will be held at CRC's corporate offices
        located at 201 South Orange Avenue, Suite 1300, Orlando, Florida
        32801, on Thursday, February 23, 1995, beginning at 11:00 a.m.
        Eastern Standard Time.

        recommendation, please read carefully the sections in the

             1.   To consider and vote upon a proposal to approve and
                  adopt the Agreement and Plan of Merger, dated January  
                  __, 1995 (the "Merger Agreement"), among CRC, Thermo

                  for the merger of Acquisition Corp. with and into CRC
                  (the "Merger") pursuant to which each share of CRC's
                  common stock, $.001 par value per share ("CRC Common
                  Stock") outstanding at the effective time of the Merger
                  (other than shares with respect to which dissenters'
                  rights are perfected) will be converted into .1905695
                  shares of Thermo's common stock, $1.00 par value per
                  share ("Thermo Common Stock"), and CRC will become a

             2.   To approve the Amended and Restated Articles of
                  Incorporation of CRC (the "Amended Articles"), which
                  deletes a current provision in CRC's Articles of
                  Incorporation, as amended, that limits stock ownership
                  to employees of CRC.  A copy of the Amended Articles is
                  attached as APPENDIX II to the accompanying Proxy
                  Statement/Prospectus.

             3.   To approve the assignment by CRC of its 49% interest in
                  Coleman Laboratories, Ltd., a limited partnership
                  ("Coleman L.P."), to entities related to Thomas J.
                  Coleman or members of his family and the termination of
                  CRC's relationship with Dr. Mohammed Katoot and MK
                  Industries Inc. ("MKI") by assigning and selling to
                  Coleman L.P. CRC's rights under certain agreements with

             4.   To transact such other business as may properly come
                  before the Special Meeting or any adjournments or
                  postponements thereof.

             The record date for the determination of shareholders
        entitled to notice of and to vote at the Special Meeting, and any
        adjournments or postponements thereof, is January 25, 1995 (the
        "Record Date").  Only holders of record of shares of CRC Common
        Stock at the close of business on the Record Date are entitled to

        accompanying this Notice of Special Meeting.

             Your vote is very important regardless of how many shares of
        CRC Common Stock you own.  Regardless of whether you plan to
        attend the Special Meeting, you are requested to sign, date and
        return the enclosed Proxy without delay in the enclosed

        Proxy and vote personally on the matters properly brought before
        the Special Meeting.

                                      By Order of the Board of Directors

                                     SUMMARY

             The following is a summary of certain information contained
        in this Proxy Statement/Prospectus concerning the proposed merger
        (the "Merger") of CRC Acquisition Corp., a Delaware corporation
        ("Acquisition Corp.") which is a wholly owned subsidiary of
        Thermo Electron Corporation, a Delaware corporation ("Thermo"),
        with and into Coleman Research Corporation, a Florida corporation
        ("CRC").  Acquisition Corp. has been formed specifically for the
        purpose of carrying out the Merger.  It is anticipated that the
        Merger will be consummated on or about February 23, 1995 (the
        "Effective Date").  This summary should be read in conjunction
        with, and is qualified in its entirety by reference to, the full
        text of this Proxy Statement/Prospectus, including the exhibits
        hereto.  Each shareholder is, therefore, urged to read the entire
        Proxy Statement/Prospectus with care.

        The Special Meeting

             The Special Meeting.  A Special Meeting of Shareholders of
        CRC will be held on Thursday, February 23, 1995, at 11:00 a.m.
        Eastern Standard Time at the corporate offices of Coleman
        Research Corporation, 201 South Orange Avenue, Suite 1300,
        Orlando, Florida  32801 (the "Special Meeting").  Shareholders of
        record at the close of business on January 25, 1995 (the "Record
        Date") will be entitled to notice of and to vote at the Special
        Meeting.  The date of the mailing of this Proxy Statement/
        Prospectus to shareholders of CRC will be on or about January 25,
        1995.  At the close of business on the Record Date, there were
        outstanding and entitled to vote 13,074,427 shares of common
        stock, $.001 par value, of CRC (the "CRC Common Stock"). 

             The purpose of the Special Meeting is (i) to vote upon a
        proposal to approve an Agreement and Plan of Merger dated January
        __, 1995 (the "Merger Agreement"), entered into by and among
        Thermo, Acquisition Corp. and CRC, pursuant to which Acquisition
        Corp. will merge with and into CRC, and Thermo will become the
        owner of all the issued and outstanding shares of CRC Common
        Stock (see "THE MERGER"); (ii) to approve the Amended and
        Restated Articles of Incorporation of CRC (the "Amended
        Articles"), which deletes a current provision in CRC's Articles
        of Incorporation, as amended, that limits stock ownership to
        employees of CRC (see "APPROVAL OF AMENDED AND RESTATED ARTICLES
        OF INCORPORATION"); and (iii) to approve the assignment by CRC of
        its 49% interest in Coleman Laboratories, Ltd., a limited
        partnership ("Coleman L.P."), to entities related to Thomas J.
        Coleman or members of his family and the termination of CRC's
        relationship with Dr. Mohammed Katoot and MK Industries Inc.
        ("MKI") by assigning and selling to Coleman L.P. CRC's rights
        under certain agreements with Dr. Katoot and MKI and certain
        equipment currently used by MKI (the "Coleman Laboratories
        Transaction") (see "APPROVAL OF THE COLEMAN LABORATORIES
        TRANSACTION").  The Merger Agreement (including the principal
        exhibits thereto), the Amended Articles and the Form of
                                        9

<PAGE>





        Assignment Agreement with respect to the Coleman Laboratories
        Transaction are attached to this Proxy Statement/Prospectus as
        APPENDIX I, APPENDIX II and APPENDIX III, respectively.

             Required Vote.  Approval of both the Merger Agreement and
        the Amended Articles requires the affirmative vote of the holders
        of a majority of the outstanding shares of CRC Common Stock.
        Approval of the Coleman Laboratories Transaction requires the
        affirmative vote of the holders of a majority of the shares
        entitled to vote at the Special Meeting, excluding the shares
        beneficially owned by Thomas J. Coleman and members of his
        family.  Certain CRC shareholders, who own an aggregate of
        8,026,330 shares of CRC Common Stock, constituting approximately
        61% of such shares outstanding, have agreed to vote all shares of
        CRC Common Stock held by them in favor of the Merger Agreement
        and the Amended Articles.  Certain CRC shareholders, who own an
        aggregate of 2,456,533 shares of CRC Common Stock, constituting
        approximately 33% of the shares of CRC Common Stock outstanding
        (excluding shares beneficially owned by Thomas J. Coleman and
        members of his family), have agreed to vote all shares of CRC
        Common Stock held by them in favor of the Coleman Laboratories
        Transaction.   The approval of the Coleman Laboratories
        Transaction is a condition of Thermo's obligation to consummate
        the Merger.  Accordingly, Thermo reserves the right to terminate
        the Merger Agreement and to decline to consummate the Merger in
        the event that the Coleman Laboratories Transaction is not
        approved by CRC shareholders.  See "SPECIAL MEETING -- Votes
        Required" and "THE MERGER -- Interests of Certain Persons in the
        Merger." 

        The Merger

             Effective Date.  The Merger shall become effective upon the
        later of the date of filing of a Certificate of Merger with the
        Secretary of State of the State of Delaware pursuant to Section
        252 of the Delaware General Corporation Law and the date of
        filing of Articles of Merger with the Secretary of State of the
        State of Florida pursuant to Section 607.1107 of the Florida
        Business Corporation Act (the "Effective Date").  It is
        anticipated that the Effective Date will be on or about February
        23, 1995.

             Exchange of Shares; Fractional Shares.  Upon consummation of
        the Merger, each outstanding share of CRC Common Stock (other
        than shares held in CRC's treasury and shares with respect to
        which statutory dissenters' rights are perfected) will be
        converted into the right to receive .1905695 shares of Thermo
        common stock, $1.00 par value (the "Thermo Common Stock"), and
        Thermo will become the owner of all of the issued and outstanding
        shares of CRC Common Stock.  No fractional shares of Thermo
        Common Stock will be issued in connection with the Merger.  Any
        CRC shareholder otherwise entitled to a fractional share of
        Thermo Common Stock as a result of the Merger shall receive cash
        in lieu thereof, without interest, in an amount determined by
                                       10

<PAGE>





        multiplying such CRC shareholder's fractional interest by the
        closing price of Thermo Common Stock as reported on the New York
        Stock Exchange on the Effective Date.  See "THE MERGER --
        Procedure for Exchange of Shares; Fractional Shares."

             Based on the number of outstanding shares of CRC Common
        Stock as of the Record Date, and assuming that (i) no CRC
        shareholders exercise appraisal rights and (ii) no options to
        purchase CRC Common Stock are exercised prior to the Merger,
        approximately 2,491,588 shares of Thermo Common Stock will be
        issued to former CRC shareholders upon the consummation of the
        Merger.  As a result, a total of approximately 53,349,065 shares
        of Thermo Common Stock will then be outstanding, of which
        approximately 2,491,588 shares, representing 4.67% of the total,
        will be held by former holders of CRC Common Stock.

             Assumption of CRC Stock Options.  At or prior to the
        Effective Date, Thermo and CRC shall take all action necessary to
        cause the assumption by Thermo as of the Effective Date of the
        options to purchase CRC common stock outstanding as of the
        Effective Date (the "CRC Options").  Each of the CRC Options
        shall be converted without any action on the part of the holder
        thereof into an option to purchase shares of Thermo Common Stock
        as of the Effective Date.  As of the Record Date, 931,786 shares
        of CRC Common Stock were subject to outstanding CRC Options,
        which would be equivalent to approximately 177,570 shares of
        Thermo Common Stock after conversion.  See "THE MERGER --
        Assumption of CRC Stock Options."

             Indemnification of Thermo; Escrow.  Ten percent of the
        shares of Thermo Common Stock issued in the Merger, including
        shares to be issued to the CRC 401(k) Employee Stock Ownership
        Plan, will be delivered into escrow (the "Escrowed Shares") and
        held pursuant to the Indemnification and Stock Escrow Agreement
        attached as Exhibit B to the Merger Agreement (the "Escrow
        Agreement").  The Escrowed Shares will be reserved to provide
        indemnification to Thermo against damages incurred as a result of
        misrepresentations, breaches of warranties and breaches of
        covenants contained in the Merger Agreement, the Escrow Agreement
        and the other agreements executed in connection therewith, and to
        satisfy claims of Thermo arising as a result of the Merger
        Agreement, the Escrow Agreement and such other agreements.  See
        Article 3 of the Merger Agreement and Section 4 of the Escrow
        Agreement for a description of the representations and warranties
        that are covered by the Escrow Agreement.  In the event Thermo
        has an appropriate claim for indemnification, shares of Thermo
        Common Stock will be returned to Thermo in satisfaction of the
        claim.  However, Thermo will be entitled to indemnification only
        if and when the total of all Indemnifiable Amounts exceeds
        $500,000, at which point Thermo will be entitled to
        indemnification for all Indemnifiable Amounts, and not just those
        in excess of $500,000.  The Escrow Agreement requires the escrow
        agent to deliver to the shareholders the Escrowed Shares
        remaining in escrow one year after the Effective Date, except
                                       11

        that if there is a claim by Thermo at or prior to such date, the
        Escrow Agent will retain Escrowed Shares in an amount sufficient
        to cover such claims until they are resolved.  See "THE MERGER --
        Indemnification of Thermo; Escrow." 

             Conditions to the Merger.  The consummation of the Merger is
        conditioned upon, among other things, (i) approval of the Merger
        and the adoption of the Merger Agreement by CRC Shareholders,
        (ii) the holders of not more than 3% of the shares of CRC Common
        Stock having demanded their right to an appraisal of their CRC
        Common Stock, and (iii) the representations and warranties of
        each party to the Merger Agreement being true and correct as of
        the Effective Date and the satisfaction of certain other
        conditions.  The Merger Agreement may be terminated by the mutual
        consent of the Boards of Directors of Thermo and CRC.  If the
        Merger is not consummated, CRC intends to operate in
        substantially the same manner as it has in the past.  Any of the
        conditions to the Merger may be waived at any time prior to the
        Merger by the party or parties to the Merger Agreement benefiting
        from such conditions.  However, no assurance can be given that
        any of such parties will determine to waive any unfulfilled
        conditions.  See "THE MERGER -- Conditions to Consummation of the
        Merger."  

             Certain Effects of the Merger.  If the Merger is
        consummated, the holders of CRC Common Stock (other than holders
        of shares with respect to which dissenters' rights are perfected)
        will exchange their shares of stock for Thermo Common Stock.  The
        rights of CRC shareholders, which are presently governed by
        Florida law and by the Articles of Incorporation and the By-laws
        of CRC, each as amended, will be governed by Delaware law and the
        Amended and Restated Certificate of Incorporation and By-laws of
        Thermo.  Certain differences in the rights of CRC shareholders
        will arise as a result of this change in governing law as well as
        from distinctions between the Articles of Incorporation and
        By-laws of CRC, as amended, and the Amended and Restated
        Certificate of Incorporation and By-laws of Thermo.  See "THE
        MERGER -- Certain Effects of the Merger" and "COMPARISON OF
        RIGHTS OF HOLDERS OF THERMO COMMON STOCK AND CRC COMMON STOCK."

             Interests of Certain Persons in the Merger.  Upon
        consummation of the Merger, Mr. Thomas J. Coleman, the sole
        member of CRC's Board of Directors, will resign, and Thermo will
        name certain senior employees of Thermo and of CRC to CRC's
        Board.  Thermo intends that certain of the existing officers of
        CRC will retain their offices after the Effective Date, but may
        also appoint additional officers of CRC.  See "THE MERGER --
        Interests of Certain Persons in the Merger," THERMO AND CRC
        MANAGEMENTS -- CRC Executive Officer and Director Compensation"
        and "APPROVAL OF THE COLEMAN LABORATORIES TRANSACTION."

        Rights of Dissenting Shareholders


                                       12

<PAGE>





             Under Florida law, shareholders who have not voted for the
        Merger Agreement (collectively, "Dissenting Shareholders"), may,
        under varying circumstances, receive cash in the amount of the
        fair market value (as determined by agreement with CRC or by
        court) of their shares in lieu of the shares of Thermo Common
        Stock they would otherwise receive in the Merger.  Such
        Dissenting Shareholders must (i) deliver to CRC, before the vote
        on the Merger Agreement is taken at the Special Meeting, written
        notice of such Dissenting Shareholders' intent to demand payment
        for their shares of CRC Common Stock and (ii) not vote such
        shares of CRC Common Stock in favor of the Merger Agreement.
        Dissenting Shareholders must also comply with the other
        requirements of Section 607.1320 of the Florida Business
        Corporation Act, the full text of which is attached to this Proxy
        Statement/Prospectus as APPENDIX IV.  Any deviation from or
        failure to comply with all such requirements may result in the
        forfeiture of the rights of Dissenting Shareholders.  See "RIGHTS
        OF DISSENTING SHAREHOLDERS."

        It is not anticipated that prior to the Merger, Acquisition Corp.
        will have any significant assets or liabilities other than its
        rights and obligations under the Merger Agreement, or that
        Acquisition Corp. will engage in any activities other than those
        incidental to its formation and the transactions contemplated by
        the Merger Agreement.

             The principal executive offices of CRC are located at 201
        South Orange Avenue, Suite 1300, Orlando, Florida 32801

        "CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS." 

        Market Prices

             The high, low and closing prices of Thermo's Common Stock on
        the New York Stock Exchange Composite Transactions Tape on August
        9, 1994, the date preceding the public announcement of the
        proposed Merger, were $41 1/4, $41 and $41 1/8, respectively.
        The high, low and closing prices of Thermo's Common Stock on the
        New York Stock Exchange Composite Transactions Tape on December
        15, 1994 were $43.75, $42.625 and $43.00, respectively.
        Shareholders of CRC are urged to obtain current quotations for
        the Thermo Common Stock.

             The CRC Common Stock is not currently, and has never
        previously been, traded on any established public market.  Price
        quotations for CRC Common Stock are, therefore, not available.
        CRC's Articles of Incorporation, as amended, require CRC to
        obtain an annual appraisal of the CRC Common Stock as of December
        31 of each year.  The appraised value of the CRC Common Stock is
        deemed to be effective as of July 1 of the subsequent year.  The
        appraised values of the CRC Common Stock as of December 31, 1992
        and December 31, 1993 were $3.00 and $5.11 per share,
        respectively ($15.74 and $26.81 on an equivalent per share basis
        assuming an exchange ratio of .1905695 shares of Thermo Common
        Stock for each share of CRC Common Stock). 

             As of December 15, 1994, there were 6,242 record holders of
        Thermo Common Stock and 432 record holders of CRC Common Stock.

        Ownership of Securities

             At the Record Date, there were a total of 13,074,427 shares
        of CRC Common Stock outstanding.  Accordingly, the Merger will be
        approved if 6,537,214 shares of CRC Common Stock are voted in
        favor of the Merger.  As of the Record Date, CRC's sole director,
        CRC's executive officers, and their respective affiliates held,
        directly or indirectly, 8,026,330 shares of CRC Common Stock, or
        approximately 61% of the shares of CRC Common Stock outstanding
        as of such date.  In addition, options to purchase 931,786 shares
        of CRC Common Stock were outstanding on the Record Date, the
        average exercise price of which was $2.32 per share.  See "THE
        MERGER -- Interests of Certain Persons in the Merger" and
        "OWNERSHIP OF CRC COMMON STOCK AND THERMO COMMON STOCK." 

             At the date hereof approximately 5.65% of the shares of
        outstanding Thermo Common Stock entitled to vote are held by
                                       14

<PAGE>





        directors and executive officers of Thermo and their affiliates.
        The vote of stockholders of Thermo is not required to approve the
        Merger Agreement or to consummate the Merger.  See "THE MERGER --
        Background of the Merger and Related Matters."

        Resale of Thermo Common Stock Received in the Merger; Affiliates

             Certain officers, directors and principal shareholders of
        CRC have agreed that, until such time as financial results
        covering at least thirty days of combined operations of CRC and
        Thermo have been published by Thermo, they will not sell,
        transfer or otherwise dispose of, or offer or agree to sell,
        transfer or otherwise dispose of any shares of Thermo Common
        Stock received by them pursuant to the Merger or any securities
        which may be paid as a dividend or otherwise distributed thereon
        or with respect thereto or issued or delivered in exchange or
        substitution therefor.  See "THE MERGER -- Resale of Thermo
        Common Stock Received in the Merger; Affiliates."

             The Registration Statement and this Proxy Statement/
        Prospectus do not relate to or cover the resale after the
        Effective Date of shares of Thermo Common Stock issued to certain
        shareholders of CRC in the Merger who may be deemed to be
        "affiliates" of CRC and thus "underwriters" within the meaning of
        Rule 145 under the Securities Act of 1933, as amended (the
        "Securities Act"), and no person is authorized to make any use of
        this Proxy Statement/Prospectus in connection with any such
        resale.  Such securities may not be publicly reoffered or resold
        by such persons except pursuant to an effective registration
        statement under the Securities Act or pursuant to another
        applicable exemption therefrom.  For this purpose, the term
        "affiliate" means any person who, directly, or indirectly through
        one or more intermediaries, possesses the power to direct or
        cause the direction of the management and policies of CRC,
        whether through the ownership of CRC Common Stock, by contract,
        or otherwise.

        Accounting Treatment; Regulatory Approvals

             The Merger is expected to meet all of the conditions for
        pooling-of-interests accounting.  It is a condition to the
        obligation of Thermo to consummate the Merger that Thermo shall
        have received an opinion from Thomas, Beck & Zurcher, P.A., CRC's
        independent accountants, to the effect that Thomas, Beck &
        Zurcher, P.A. is not aware of any fact concerning CRC that would
        preclude Thermo from accounting for the Merger as a pooling-of-
        interests.

             The Merger is subject to the requirements of the
        Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the
        regulations thereunder (the "Antitrust Improvements Act"), which
        provide that certain acquisition transactions (including the
        Merger) may not be consummated until certain information has been
        furnished to the Antitrust Division of the Department of Justice
                                       15
PAGE
<PAGE>





        (the "Antitrust Division") and the Federal Trade Commission (the
        "FTC"), and certain waiting period requirements have been
        satisfied.  Thermo and CRC have filed the required information
        and material with the Antitrust Division and the FTC and the
        applicable waiting period terminated on January __, 1995.
        Termination of the waiting period does not preclude the Antitrust
        Division, the FTC or any other party from challenging or seeking
        to delay or enjoin the Merger on antitrust or other grounds.
        There can be no assurance that such a challenge, if made, would
        not be successful; however, neither Thermo nor CRC believes that
        the Merger will violate the antitrust laws.  Any such action
        taken or threatened prior to the consummation of the Merger could
        relieve Thermo or CRC of their respective obligations to
        consummate the Merger.  See "THE MERGER."

             Except for the Antitrust Improvements Act filings, and
        filings with the Secretary of State of the States of Delaware and
        Florida, no federal or state regulatory approvals are required in
        order to consummate the Merger.

        Certain Federal Income Tax Consequences

             The Merger is intended to qualify as a tax-free
        reorganization under Section 368(a) of the Internal Revenue Code
        of 1986, as amended (the "Code").  Neither CRC nor Thermo intend
        to request a ruling from the Internal Revenue Service with
        respect to the Merger.  Assuming that the Merger is a tax-free
        reorganization, (i) no gain or loss will be recognized by Thermo
        or CRC and (ii) no gain or loss will be recognized by
        shareholders of CRC other than shareholders perfecting statutory
        dissenters' rights or in connection with the cash settlement of
        fractional shares.  If the Merger fails to qualify as a
        reorganization under Section 368(a) of the Code, on the Effective
        Date each shareholder of CRC will recognize gain or loss on the
        exchange of his CRC Common Stock for Thermo Common Stock.  See
        "CERTAIN FEDERAL INCOME TAX CONSEQUENCES."  Holders of CRC Common
        Stock are urged to consult with their tax advisers to determine
        the particular tax consequences of the Merger to them.

                                      Selected Financial Information

     The following selected consolidated financial data for the year ended December 31, 1993 has been
derived from the CRC Consolidated Financial Statements, which have been audited by Thomas, Beck, &
Zurcher, P.A., independent public accountants as indicated in their report included elsewhere in this
Prospectus. The financial data for the four years ended December 31, 1992 has been derived from the
unaudited CRC Consolidated Financial Statements, which have been reviewed by Thomas, Beck, & Zurcher,
P.A. This information should be read in conjunction with the CRC Consolidated Financial Statements and
related notes included elsewhere in this Prospectus. The selected information for the four years ended
December 31, 1992 and for the nine-month periods ended September 30, 1993 and September 30, 1994 has not
been audited but, in the opinion of CRC, includes all adjustments (consisting only of normal, recurring
adjustments) necessary to present fairly such information in accordance with generally accepted
accounting principles applied on a consistent basis. The result of operations for the nine-month period
ended September 30, 1994 are not necessarily indicative of results for the entire year.

     The following table presents selected pro forma combined financial information for Thermo and
CRC and selected per share data for Thermo Common Stock and CRC Common Stock on a historical and pro
forma combined basis and for CRC Common Stock on a pro forma equivalent basis giving effect to the
acquisition of 100% of the CRC shares by Thermo on a pooling-of-interests accounting basis. The
information is derived from the consolidated historical financial statements of Thermo and CRC,
including the related notes thereto, appearing elsewhere and incorporated by reference herein. The
pro forma statement of income data for each period gives effect to the acquisition as if it had
occurred at the beginning of such period, and the pro forma balance sheet data gives effect to the
acquisition as if it had occurred on the balance sheet date. The pro forma combined information has
been prepared on the assumption that the acquisition will be accounted for on a pooling-of-interests
basis.
     Equivalent per share data for CRC Common Stock has been calculated based on the pro forma
combined data for Thermo Common Stock multiplied by .1905695, which is the number of Thermo shares
into which each share of CRC Common Stock would be exchanged pursuant to the Merger, excluding
any affect from the assumption of CRC stock options.
     These data are not necessarily indicative of the results of the future operations of the
combined entity or the actual results that would have occurred had the CRC acquisition been
consummated prior to the periods indicated.

(1)  The pro forma combined book values per share of Thermo Common Stock are based upon the
     historical total common equity for Thermo and CRC, divided by total pro forma common shares of
     the combined entity. The pro forma equivalent book values per share of CRC Common Stock
     represent the pro forma combined amounts multiplied by .1905695, which is the number of shares
     of Thermo Common Stock into which each share of CRC Common Stock would be exchanged pursuant to
     the Merger.
(2)  The pro forma combined earnings per share before cumulative effect of change in accounting
     principle is based upon the combined historical income before cumulative effect of change in
     accounting principle for Thermo and CRC divided by the average pro forma common shares of the
     combined entity. The pro forma equivalent earnings per share before cumulative effect of change
     in accounting principle of CRC Common Stock represents the pro forma combined amounts
     multiplied by .1905695, which is the number of shares of Thermo Common Stock into which each
     share of CRC Common Stock would be exchanged pursuant to the Merger.

                                 SPECIAL MEETING

        General

             This Proxy Statement/Prospectus is being furnished to
        holders of CRC Common Stock in connection with the solicitation
        of proxies by the Board of Directors of CRC for use at the CRC
        Special Meeting, which will be held at CRC's corporate offices
        located at 201 South Orange Avenue, Suite 1300, Orlando, Florida
         32801, on  Thursday, February 23, 1995, beginning at 11:00 a.m.
        Eastern Standard Time, and at any adjournments or postponements
        thereof.  This Proxy Statement/Prospectus is accompanied by a
        form of proxy for use at the Special Meeting.

             This Proxy Statement/Prospectus also constitutes the
        Prospectus of Thermo with respect to the shares of Thermo Common
        Stock to be issued pursuant to the Merger, which Prospectus is
        part of a Registration Statement on Form S-4 filed by Thermo with
        the Commission under the Securities Act of 1933, as amended (the
        "Securities Act").

             No vote by the stockholders of Thermo is required to
        consummate the Merger.

        Purposes; Recommendation of the CRC Board of Directors and
        Management

             The purposes of the Special Meeting are (i) to consider and
        vote upon a proposal to adopt and approve the Merger Agreement
        and the transactions contemplated thereby, (ii) to approve the
        Amended Articles of CRC, which deletes a current provision in
        CRC's Articles of Incorporation, as amended, that limits stock
        ownership to employees of CRC, (iii) to approve the assignment by
        CRC of its 49% interest in Coleman Laboratories, Ltd., a limited
        partnership ("Coleman L.P."), to entities related to Thomas J.
        Coleman or members of his family and the termination of CRC's
        relationship with Dr. Mohammed Katoot and MK Industries Inc.
        ("MKI") by assigning and selling to Coleman L.P. CRC's rights
        under certain agreements with Dr. Katoot and MKI and certain
        equipment currently used by MKI (the "Coleman Laboratories
        Transaction"), and (iv) to transact such other business as may
        properly come before the Special Meeting and any adjournments or
        postponements thereof.  The Board of Directors of CRC is not
        presently aware of any such other business.  See "THE MERGER,"
        "APPROVAL OF AMENDED AND RESTATED ARTICLES OF INCORPORATION" and
        "APPROVAL OF THE COLEMAN LABORATORIES TRANSACTION."

             The management of CRC, including Thomas J. Coleman, the sole
        member of CRC's Board of Directors, have approved the Merger
        Agreement and the transactions contemplated thereby and believe
        the Merger and the other transactions contemplated by the Merger
        Agreement are fair to and in the best interests of CRC and its
        shareholders.  THE MANAGEMENT AND BOARD OF DIRECTORS OF CRC
                                       25
PAGE
<PAGE>





        RECOMMEND THAT CRC SHAREHOLDERS VOTE IN FAVOR OF THE ADOPTION AND
        APPROVAL OF THE MERGER AGREEMENT AND THE TRANSACTIONS
        CONTEMPLATED THEREBY, INCLUDING WITHOUT LIMITATION THE APPROVAL
        OF THE AMENDED ARTICLES AND THE APPROVAL OF THE COLEMAN
        LABORATORIES TRANSACTION.

        Record Date

             Only holders of record of CRC Common Stock as of the close
        of business on January 25, 1995 are entitled to receive notice of
        and to vote at the Special Meeting and any adjournments or
        postponements thereof.  As of the close of business on January
        25, 1995, 13,074,427 shares of CRC Common Stock were outstanding.
        Each share of CRC Common Stock is entitled to one vote upon each
        matter properly submitted at the Special Meeting.

        Votes Required            

             Under Florida law and pursuant to CRC's Articles of
        Incorporation and the CRC By-laws, each as amended, the
        affirmative vote of the holders of at least a majority of the
        outstanding shares of CRC Common Stock is required to adopt and
        approve the Merger Agreement and the transactions contemplated
        thereby, including the approval of the Amended Articles.
        Approval of the Coleman Laboratories Transaction requires the
        affirmative vote of the holders of a majority of the shares
        entitled to vote at the  Special Meeting, excluding the shares
        beneficially owned by Thomas J. Coleman and members of his
        family.  

             The presence, in person or by proxy, at the Special Meeting
        of the holders of at least a majority of the votes entitled to be
        cast at the Special Meeting is necessary to constitute a quorum
        for the transaction of business.  Abstentions will be counted as
        present for the purposes of determining whether a quorum is
        present but will not be counted as votes cast in favor of the
        Merger Agreement or the approvals of the Amended Articles or the
        Coleman Laboratories Transaction.  Because the votes on the
        Merger Agreement, the Amended Articles and the Coleman
        Laboratories Transaction require the approval of a majority of
        the votes entitled to be cast by the holders of the outstanding
        shares of CRC Common Stock, abstentions will have the same effect
        as a negative vote on these proposals.  

             As of the Record Date, the sole director and the executive
        officers of CRC, together with their affiliates,  beneficially
        owned an aggregate of 8,026,330 shares of CRC Common Stock,
        constituting approximately 61% of the then outstanding CRC Common
        Stock.  Each of the directors and executive officers of CRC have
        agreed with Thermo to vote their shares of CRC Common Stock in
        favor of the proposals to adopt and approve the Merger Agreement
        and to approve the Amended Articles, ensuring the adoption and
        approval of the Merger Agreement and the Amended Articles by the
        CRC shareholders without regard to the votes of any other CRC
                                       26

<PAGE>





        shareholders.  Approval of the Coleman Laboratories Transaction
        will require the affirmative vote of the holders of 1,295,783
        shares of CRC Common Stock in addition to the shares of CRC
        Common Stock held directly or indirectly by the executive
        officers of CRC.  The approval of the Coleman Laboratories
        Transaction is a condition of Thermo's obligation to consummate
        the Merger.  Accordingly, Thermo reserves the right to terminate
        the Merger Agreement and to decline to consummate the Merger in
        the event that the Coleman Laboratories Transaction is not
        approved by the CRC shareholders.  

        Voting and Revocation of Proxies

             Shares of CRC Common Stock that are entitled to vote and are
        represented by a proxy properly signed and received at or prior
        to the Special Meeting, unless subsequently properly revoked,
        will be voted in accordance with the instructions indicated
        thereon.  If a proxy is signed and returned without indicating
        any voting instructions, shares of CRC Common Stock represented
        by such proxy will be voted FOR the proposal to adopt and approve
        the Merger Agreement and the transactions contemplated thereby,
        including the proposals to approve the Amended Articles and the
        Coleman Laboratories Transaction.  The Board of Directors of CRC
        is not currently aware of any business to be acted upon at the
        Special Meeting other than as described herein.  If, however,
        other matters are properly brought before the Special Meeting or
        any adjournments or postponements thereof, the persons appointed
        as proxies will have the discretion to vote or act thereon in
        accordance with their best judgment.

             Any proxy given pursuant to this solicitation may be revoked
        by the person giving it at any time before the shares represented
        by such proxy are voted at the Special Meeting by (i) filing with
        the Secretary of CRC a written notice of revocation bearing a
        later date than the proxy, (ii) duly executing a proxy relating
        to the same shares bearing a later date and delivering it to the
        Secretary of CRC, or (iii) voting in person at the Special
        Meeting.  Attendance at the Special Meeting will not in and of
        itself constitute a revocation of a proxy.  All written notices
        of revocation and other communications with respect to revocation
        of proxies should be addressed as follows:  Coleman Research
        Corporation, 201 South Orange Avenue, Suite 1300, Orlando,
        Florida  32801, Attention: Secretary, and must be received before
        the taking of the vote at the Special Meeting.

        Solicitation of Proxies

             Thermo will bear the costs incurred in preparing this Proxy
        Statement/Prospectus (and the related Registration Statement) and
        the form of proxy, except that CRC will bear the costs of mailing
        proxy materials to CRC shareholders in connection with the
        Special Meeting.  In addition to solicitation by mail, directors,
        officers and employees of CRC, who will not be specifically
        compensated for such services, may solicit proxies from CRC
                                       27

        shareholders personally or by telephone, telecopy, telegram or
        other means of communication.

        Dissenters' Rights

             Shareholders of CRC who do not vote in favor of the adoption
        and approval of the Merger Agreement and the transactions
        contemplated thereby (collectively, "Dissenting Shareholders")
        have certain rights to demand payment for the "fair value" of
        their shares of CRC Common Stock if they timely provide a written
        notice of dissent prior to the Special Meeting and strictly
        comply with all other applicable requirements under Florida law.
        Failure to take any of the steps required on a timely basis will
        result in the loss of dissenters' rights.  Merely voting against
        or failing to vote for the Merger Agreement will not perfect a
        Dissenting Shareholder's dissenter's rights.  The amount
        obtainable upon the valid exercise of dissenters' rights cannot
        be predicted.  The procedures to be followed by Dissenting
        Shareholders are summarized in "RIGHTS OF DISSENTING
        SHAREHOLDERS," and a copy of the applicable provisions of the
        Florida Business Corporation Act are attached as APPENDIX IV to
        this Proxy Statement/Prospectus and incorporated herein by this
        reference.

             CRC SHAREHOLDERS SHOULD NOT SEND ANY STOCK CERTIFICATES WITH
        THEIR PROXY CARDS.


                               -- PROPOSAL ONE --

                                   THE MERGER

        Background of the Merger and Related Matters

             Thermo and CRC have worked together on several projects over
        the past five years.  Beginning in 1990, CRC was a subcontractor
        to Thermo's Thermedics Inc. subsidiary ("Thermedics") in the
        development of a hand-held mine detection system for the U.S.
        Department of Defense.  Under this contract, the two companies
        were to combine CRC's ground-penetrating radar with Thermedics'
        chemical detection technology into a single system.

             Beginning in 1993, Thermedics became a subcontractor to CRC
        in the development of a robotically controlled vehicle to perform
        chemical analysis of potentially contaminated facilities for the
        U.S. Department of Energy.

             In August 1994, CRC and Thermo, as members of a team led by
        Lockheed Corporation, were chosen by the U.S. Department of
        Energy to manage the Idaho National Engineering Laboratories
        ("INEL") in Idaho Falls.  A central feature of the contract was a
        plan for Thermo's Thermo Technology Ventures Inc. subsidiary
        ("TTV") to identify potential opportunities to spin out companies
        to commercialize technologies originated in INEL.

             Over the past several years, CRC's senior management had
        been engaged in internal discussions with respect to CRC's future
        direction.  During this period, CRC had considered and then
        rejected proposals from several companies to acquire CRC.  In
        preparing the Lockheed bid, Messrs. Martin R. Adams and Buddy G.
        Beck, each a Corporate Vice President of CRC, became aware of
        Thermo's capability to commercialize technologies.  In late 1993,
        Messrs. Robert C. Howard, Executive Vice President of Thermo,
        Marshall J. Armstrong, Vice President of Thermo, and Thomas F.
        Widmer, President of TTV, met with Messrs. Adams and Beck to
        discuss opportunities for Thermo to commercialize CRC's
        technologies.

             In January 1994, Messrs. Thomas J. Coleman, CRC's principal
        stockholder and sole director, James B. Morrison, CRC's
        President, and Richard H. Levine, CRC's Chief Financial Officer,
        along with Messrs. Adams and Beck, met in Thermo's executive
        offices with Dr. George N. Hatsopoulos, President and Chief
        Executive Officer of Thermo, Dr. John P. Appleton, a Vice
        President of Thermo and the President and Chief Executive Officer
        of Thermo's Thermo Process Systems Inc. subsidiary, Mr. Theo
        Melas-Kyriazi, then-Treasurer of Thermo, and Messrs. Howard and
        Armstrong, to continue discussions with respect to the potential
        for Thermo to commercialize CRC technology and to tour one of the
        facilities of Thermo's Thermo Power Corporation subsidiary.

             Several days subsequent to this meeting, after interim
        discussions between Mr. Beck and Mr. Howard, Mr. Morrison and Mr.
        Howard discussed the possibility of merging CRC into Thermo.  The
        two men had general discussions regarding both the structure of
        such a transaction and the range of purchase prices at which an
        acquisition would be acceptable to both  companies.  They agreed
        that a tax-free exchange of stock would be preferable to a cash
        transaction, and considered various methods of determining the
        number of shares of Thermo Common Stock to be issued pursuant to
        the proposed transaction.

             On March 8, 1994, Messrs. Coleman, Morrison, Adams and Beck
        met with Mr. Howard in Washington, D.C. to continue their
        preliminary discussions with respect to the transaction, the
        purchase price, continuity of CRC management and the two
        companies' operating philosophies.  Based on these satisfactory
        discussions, a series of meetings was initiated in which CRC
        would present to Thermo an overview of all of its programs and
        technologies.

             On March 28, 1994, Messrs. Howard, Armstrong and Widmer,
        together with Mr. Paul F. Kelleher, Thermo's Chief Accounting
        Officer, met in CRC's executive offices to begin the review of  
        CRC's technologies and to consider how the two companies might be
        integrated.  In May 1994, Mr. Armstrong again traveled to CRC's
        executive offices to continue these discussions.

             In May, 1994, Messrs. Coleman and Morrison attended the 1994
        Annual Meeting of Thermo Shareholders in Hilton Head, South
        Carolina.  At this meeting, Messrs. Coleman and Morrison received
        presentations on Thermo and its public and private subsidiaries
        and met additional members of Thermo's management.

             On August 8, 1994, Mr. Howard and Mr. Morrison had a
        telephone conversation in which Mr. Howard indicated that Thermo
        was interested in purchasing CRC in a tax-free exchange of stock
        that would qualify as a pooling-of-interests for accounting
        purposes in which 2,656,000 shares of Thermo Common Stock would
        be issued to the shareholders and optionholders of CRC.  On
        August 10, 1994, Thermo issued  a press release announcing that
        it had signed a letter of intent to acquire CRC.

             Numerous telephone conversations and meetings among counsel
        for Thermo and CRC and among representatives of Thermo and CRC
        subsequently ensued.  During the months of September through
        December 1994, Thermo and CRC negotiated the terms of the Merger
        Agreement and related agreements.  Simultaneously, Thermo
        completed its business review of CRC.  On November 18, 1994,
        Thermo agreed to increase to 2,669,158 the number of shares of
        Thermo Common Stock to be issued to shareholders and
        optionholders of CRC.  The Merger Agreement was executed on
        January __, 1995.  The Board of Directors of Thermo approved the
        acquisition by Thermo of CRC on January __, 1995.  A vote of the
        stockholders of Thermo is not required to adopt the Merger
        Agreement.

        Thermo's Reasons for the Merger

             Thermo's purpose for engaging in the transactions
        contemplated by the Merger Agreement is to acquire CRC.  Thermo
        believes that the acquisition of CRC will provide Thermo with an
        established, well-recognized provider of systems integration,
        systems engineering, and analytical services to both government
        and industry.  At the same time, Thermo hopes both to identify
        opportunities to commercialize CRC's existing technologies and to
        combine its research and development activities with those of CRC
        with a goal of creating new technologies.  The structure of the
        Merger was established to achieve the business objectives of
        Thermo, in light of relevant financial, legal, tax and other
        considerations.  See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES."

        CRC's Reasons for the Merger

             The management of CRC, including Thomas J. Coleman, the sole
        member of the Board of Directors of CRC, believe that the terms
        of the Merger are fair to, and in the best interests of, CRC and
        its shareholders and unanimously approve the Merger Agreement and
        the transactions contemplated thereby.  CRC believes that a
        number of significant strategic benefits will accrue from the
        Merger.  CRC, through funding received from the government and
        through internal research, has developed a number of technologies
                                       30
PAGE
<PAGE>





        that it believes have potential commercial applications.  Thermo
        has demonstrated a long-term record of commercializing
        technologies.  CRC's management believes that CRC's technology
        base, coupled with Thermo's access to capital and expertise in
        technology commercialization, will be of significant benefit to
        CRC and its employees.  There can be no assurances, however, that
        the shareholders of CRC will realize all of the benefits expected
        from the Merger.

             In evaluating the Merger, the Board of Directors and
        management of CRC considered and evaluated, among other things,
        (i) the consideration offered by Thermo for the outstanding
        shares and options to purchase shares of CRC Common Stock; (ii)
        information concerning the results of operations, performance,
        financial condition and prospects of Thermo; (iii) the technology
        and customer base of Thermo's business, (iv) the prospects for
        future growth in value of Thermo's Common Stock; (v) current
        economic, industry and market conditions affecting both CRC and
        Thermo; (vi) the terms of the Merger Agreement; (vii) the
        tax-free nature of the Merger; (viii) CRC's graduation from its
        present, preferred "small business" status for certain government
        business; and (ix) the potential impact of the Merger on CRC's
        employees and customers.  Based on all of these matters, and such
        other matters as CRC deemed relevant, the Board of Directors and
        management of CRC unanimously support the Merger Agreement and
        recommend that the holders of CRC Common Stock vote for its
        approval and adoption. 

             Diversification.  In 1991 CRC's management focused on the
        need to pursue its strategy to broaden CRC's business beyond its
        traditional core defense businesses.  This diversification
        strategy was developed in response to uncertainties regarding
        future levels of  U.S. Government defense budgets and other
        possible reductions by customers in CRC's traditional core
        businesses.  CRC has historically served the government
        marketplace and, within that, primarily the Department of
        Defense.  In recent years, CRC has made major thrusts into
        diversification into the energy and environmental, information
        technology, and health systems fields.  Thermo, through its
        public and non-public subsidiaries, has a world-wide business
        base in the energy, environmental, and health systems
        marketplaces.  This business area and market synergy is expected
        to result in growth opportunities for CRC.  Thermo's size,
        contacts and name recognition in the international marketplace is
        expected to help CRC to expand outside of its historical U.S.
        Government business and to further CRC's strategy of continued
        diversification.

             Commercialization.  As a result of years of contract
        research and development funding from the federal government, CRC
        currently possesses a number of technologies with commercial
        potential.  These technologies include, among others, information
        and data systems technology, earth penetrating radar, coherent
        laser radar, launch systems, data fusion workstation, power plant
                                       31

        control, synthetic environment training, and communication and
        tracking systems.  To achieve the full potential value of these
        technologies for CRC's shareholders would require significant
        amounts of future capital for commercialization and production.
        CRC's structure as a privately-held services company is unlikely
        to permit the adequate funding of these technologies.  Thermo's
        demonstrated ability to raise capital is expected to be a
        significant benefit in the continued development of these
        projects.

             Working Relationships.  Through the relationships described
        above, CRC has become well acquainted with Thermo, its
        subsidiaries, its management, its products, and its business
        strategy.  See "BACKGROUND OF THE MERGER AND RELATED MATTERS."

             Compatibility.  CRC has been approached by a number of firms
        since its founding about potentially acquiring CRC.  The offers
        that resulted from these discussions were not considered to
        represent the fair value of CRC and/or the acquiring corporation
        was not viewed as a good fit for the capabilities, markets,
        employees and culture of CRC.  CRC's management believes that the
        proposed Merger overcomes all of the shortcomings of previous
        offers.  In the opinion of CRC's management, the Merger with
        Thermo will provide CRC's shareholders and employees with a fair
        value for their CRC Common Stock, and CRC will become an
        important part of a growing, well-respected corporation,
        providing expanded opportunities for the growth and development
        of CRC's employees.

             Graduation from "Small Business" Status.  CRC believes that
        it continued growth at present levels, even absent a merger,
        would result in CRC graduating from its principal "small
        business" size category in early 1995.  CRC's "small business"
        status has given it a preferred status with respect to bidding on
        certain types of government business.  Therefore, CRC believes
        that the Merger with Thermo will accelerate the expected change
        in CRC's status by only a few months.  CRC's management has been
        planning for this graduation for more than a year.  It is CRC's
        management's view that no longer being a "small business" as a
        part of Thermo is a stronger position for CRC than no longer
        being a "small business" as a stand-alone corporation.

             Shareholder Value.  CRC shareholders will receive a
        significant premium over the current evaluated price of the CRC
        Common Stock.  Thermo's Common Stock, which is traded on the New
        York Stock Exchange, will provide greater liquidity to CRC's
        shareholders than may be possible with CRC Common Stock.  The CRC
        Common Stock is not currently, and has never previously been,
        traded on any established public market. 

             Summary.  The Board of Directors and management of CRC has
        concluded, in light of the above factors and such other factors
        as they have considered appropriate, that the terms of the Merger
        Agreement are fair to, and that the Merger is in the best
                                       32

        interests of, CRC and its shareholders.  Thomas J. Coleman, the
        sole director of CRC, and members of his family own beneficially
        approximately 43% of the CRC Common Stock.  For information
        concerning the interests of certain members of CRC management in
        the Merger, see "THE MERGER -- Interests of Certain Persons in
        the Merger."

        Structure and Terms of the Merger

             If the Merger is consummated, the outstanding shares of
        Acquisition Corp. will be converted into new shares of CRC Common
        Stock (which will be held by Thermo) and all of the previously
        outstanding shares of CRC Common Stock (other than any such
        shares held in the treasury of CRC and shares with respect to
        which dissenters' rights are perfected) will be converted into
        shares of Thermo Common Stock.  As a result of the Merger, CRC
        will become a wholly owned subsidiary of Thermo, and each person
        who previously held shares of CRC Common Stock (other than those
        who perfect statutory dissenters' rights) will receive, upon the
        surrender of their stock certificates to a designated agent of
        Thermo, .1905695 shares of Thermo Common Stock for each share of
        CRC Common Stock held.  A copy of the Merger Agreement is
        attached as APPENDIX I to this Proxy Statement/Prospectus and is
        incorporated herein by this reference.

             Based on the number of outstanding shares of CRC Common
        Stock as of the Record Date, and assuming that (i) no CRC
        shareholders exercise appraisal rights and (ii) no options to
        purchase CRC Common Stock are exercised prior to the Merger,
        approximately 2,491,588 shares of Thermo Common Stock will be
        issued to former CRC shareholders upon the consummation of the
        Merger.  As a result, a total of approximately 53,349,065 shares
        of Thermo Common Stock will then be outstanding, of which
        approximately 2,491,588 shares, representing approximately 4.67%
        of the total, will be held by former holders of CRC Common Stock.

        Assumption of CRC Stock Options

             At or prior to the Effective Date, Thermo and CRC shall take
        all action necessary to cause the assumption by Thermo as of the
        Effective Date of the options to purchase CRC common stock
        outstanding as of the Effective Date (the "CRC Options").  Each
        of the CRC Options shall be converted without any action on the
        part of the holder thereof into an option to purchase shares of
        Thermo Common Stock (the "Thermo Options") as of the Effective
        Date.  The number of shares of Thermo Common Stock that each
        record holder of an option agreement which represents CRC Options
        (the "Optionholders") shall be entitled to receive upon the
        exercise of such option shall be a number of whole shares
        determined by multiplying the number of shares of CRC Common
        Stock subject to such option, determined immediately before the
        Effective Date, by .1905695.  The option price of each share of
        Thermo Common Stock subject to an assumed CRC Option shall be the
        amount (rounded up to the nearest whole cent) obtained by
                                       33

<PAGE>





        dividing the exercise price per share of CRC Common Stock at
        which such option is exercisable immediately before the Effective
        Date by .1905695.  The assumption and substitution of CRC Options
        shall not give the Optionholders additional benefits which they
        did not have immediately prior to the Effective Date, result in
        any acceleration of any vesting schedule for any CRC Option,
        other than as provided for under the CRC Nonqualified Stock
        Option Plan, or relieve the Optionholders of any obligations or
        restrictions applicable to their options or the shares obtainable
        upon exercise of the options.  Only whole shares of Thermo Common
        Stock shall be issued upon exercise of any former option for CRC
        Common Stock, and the holder of such option shall receive in cash
        the fair market value of the fractional share, net of the
        applicable exercise price of the fractional share and applicable
        withholding taxes.  As of the Record Date, 931,786 shares of CRC
        Common Stock were subject to outstanding CRC Options, which would
        be equivalent to approximately 177,570 shares of Thermo Common
        Stock after conversion.  

        Indemnification of Thermo; Escrow

             Upon consummation of the Merger, 10% of the shares of Thermo
        Common Stock issued in the Merger, including shares to be issued
        to the CRC 401(k) Employee Stock Ownership Plan (the "KSOP"),
        will be delivered into escrow (the "Escrowed Shares") and held
        pursuant to the Indemnification and Stock Escrow Agreement
        attached as Exhibit B to the Merger Agreement (the "Escrow
        Agreement").  The Escrowed Shares will be reserved to provide
        indemnification to Thermo against costs, liabilities or damages
        incurred, paid by or imposed upon Thermo, Acquisition Corp. or
        CRC after the Effective Date as a result of misrepresentations,
        breaches of warranties and breaches of covenants contained in the
        Merger Agreement, the Escrow Agreement and the other agreements
        executed in connection therewith.  See Article 3 of the Merger
        Agreement and Section 4 of the Escrow Agreement for a description
        of the representations and warranties that are covered by the
        Escrow Agreement. 

             In the event Thermo has an appropriate claim for
        indemnification, shares of Thermo Common Stock held in the escrow
        account will be returned to Thermo in satisfaction of the claim.
        The amount of indemnification to which Thermo would be entitled
        with respect to an indemnifiable claim (the "Indemnifiable
        Amount") shall be determined and computed by reference to the
        actual economic loss to Thermo, Acquisition and/or CRC (and not
        just by reference to any effect on the value of the shares of
        CRC) and shall be deemed to include all losses, liabilities,
        expenses or costs incurred by Thermo and/or Acquisition,
        including reasonable attorney's fees.  For purposes of
        determining the number of shares of Thermo Common Stock which
        would be returned to Thermo in satisfaction of a claim, each
        share will be valued at the closing price of Thermo Common Stock
        on the New York Stock Exchange on the last trading date
        immediately preceding the Effective Date.  Thus, for purposes of
                                       34

        satisfying the indemnification requirements of the Escrow
        Agreement, the former CRC shareholders would not have the benefit
        of any increase, nor the risk of any decrease, in the market
        price of shares of Thermo Common Stock after the Effective Date.
        Thermo will be entitled to indemnification only if and when the
        total of all Indemnifiable Amounts exceeds $500,000, at which
        point Thermo will be entitled to indemnification for all
        Indemnifiable Amounts, and not just those in excess of $500,000.

             If a claim is made, the escrow agent will deliver to Thermo
        an amount of shares with a total value equal to the Indemnifiable
        Amount within 20 days of the demand unless written objection to
        such demand is received by the escrow agent and Thermo from the
        Shareholder Representative (as defined below).  If the
        Shareholder Representative objects to Thermo's claim, the dispute
        may be submitted to a court of competent jurisdiction if not
        previously settled.  

             The Escrow Agreement requires the escrow agent to deliver to
        the shareholders the Escrowed Shares remaining in escrow one year
        after the Effective Date, except that if there is a claim by
        Thermo at or prior to such date, the Escrow Agent will retain
        Escrowed Shares in an amount sufficient to cover such claims
        until they are resolved.  Although CRC is not aware of any claims
        threatened or asserted that it expects to give rise to a right of
        indemnification under the Escrow Agreement, it should be
        understood that claims may arise in amounts which would result in
        all of the Escrowed Shares being either distributed to Thermo or
        sold by the Shareholder Representative pursuant to the Escrow
        Agreement, in which event none of the Escrowed Shares would be
        distributed to the shareholders at the end of the escrow period.

             Shares held in escrow will be registered in the name of the
        Escrow Agent, and the shareholder will be entitled to instruct
        the Escrow Agent how to vote his shares with respect to matters
        placed before the Thermo shareholders.  CRC shareholders will be
        entitled to directly receive cash dividends, if any, paid or
        declared out of earned surplus on the Escrowed Shares during the
        escrow period; however, any additional shares of Thermo Common
        Stock or other property that are distributed with respect to the
        Escrowed Shares during the escrow period will be held pursuant to
        the Escrow Agreement to satisfy any indemnification claims.

             In the event that a KSOP participant becomes entitled to a
        distribution of benefits from the KSOP, the portion of his KSOP
        account represented by Escrowed Shares will be re-registered in
        the name of the participant.  In the alternative, if a
        participant's account balance is transferred directly to a
        qualified plan in accordance with Internal Revenue Code Section
        401(a) or to an individual retirement account in accordance with
        Internal Revenue Code Section 408, the Escrow Agent will issue a
        certificate to such individual retirement account rollover or
        direct transferred account, evidencing the participant's interest
        in such shares.  Although physical possession of the shares will
                                       35

        remain with the Escrow Agent, the Escrow Agent will issue a
        certificate to the participant evidencing the fact that the
        Escrow Agent is holding the shares in the name of the
        participant.  Additionally, the Escrow Agreement may be amended
        to permit a release of the Escrowed Shares to any KSOP
        participant who is about to receive a complete distribution from
        the KSOP, provided that the participant substitutes in the escrow
        fund an equal number of shares of Thermo Common Stock.  Counsel
        to Thermo has advised that the existence of the Escrow Agreement
        will not be a factor in determining the tax treatment of a
        complete distribution to a KSOP participant of the entire balance
        to his credit in the KSOP.  Thus, a participant who would have
        been entitled to lump sum distribution treatment under Internal
        Revenue Code Section 402(e)(4)(A) but for the existence of the
        Escrow Agreement will be entitled to such lump sum distribution
        treatment.  

             Thomas J. Coleman has agreed to serve as representative of
        the CRC shareholders for purposes of the Escrow Agreement (the
        "Shareholder Representative").  Any action taken by the
        Shareholder Representative with respect to the settlement of a
        claim against the Escrowed Shares will be binding on all CRC
        shareholders.  The Shareholder Representative will have the right
        to sell shares of Thermo Common Stock held in escrow in order to
        obtain funds to pay any expenses incurred or anticipated to be
        incurred in connection with his services.

        Procedure for Exchange of Share; Fractional Shares

             Promptly following the consummation of the Merger, The First
        National Bank of Boston, acting in the capacity of exchange agent
        (the "Exchange Agent") will mail to each former shareholder of
        CRC a form of letter of transmittal, together with instructions
        for the exchange of such holder's certificates representing CRC
        Common Stock for certificates representing shares of Thermo
        Common Stock.  Upon surrender to the Exchange Agent of one or
        more certificates for CRC Common Stock together with a properly
        completed letter of transmittal, the Exchange Agent will issue
        and mail to the former CRC shareholder a certificate representing
        a number of shares of Thermo Common Stock that is equal to 90% of
        the number of shares of Thermo Common Stock into which such
        shares of CRC Common Stock have been converted pursuant to the
        Merger, and, where applicable, a check for the amount
        representing any fractional share determined in the manner
        described in the following paragraph.  Under the Merger
        Agreement, a certificate representing the remaining 10% percent
        of the shares of Thermo Common Stock into which a CRC
        shareholder's shares of CRC Common Stock have been converted will
        be delivered into escrow and thereafter delivered to the
        shareholder or returned to Thermo in accordance with the terms of
        the Escrow Agreement.  See "THE MERGER -- Indemnification of
        Thermo; Escrow."

             Neither certificates nor scrip for fractional shares of
        Thermo Common Stock shall be issued to CRC shareholders and no
        CRC shareholder shall be entitled to any voting or other rights
        of a holder of shares or a fractional share interest.  Each CRC
        Shareholder who otherwise would have been entitled to receive a
        fraction of a share of Thermo Common Stock shall receive cash in
        lieu thereof, without interest, in an amount determined by
        multiplying such Shareholder's fractional interest by the closing
        price of Thermo Common Stock as reported on the New York Stock
        Exchange on the Effective Date.  All amounts of cash in respect
        of fractional interests which have not been claimed at the end of
        three years from the Effective Date by surrender of certificates
        of CRC Common Stock for shares of Thermo Common Stock shall be
        repaid to Acquisition Corp., subject to the provisions of
        applicable escheat or similar laws, for the account of the
        holders entitled thereto.

             CRC SHAREHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL
        THEY RECEIVE THE LETTER OF TRANSMITTAL FORM AND INSTRUCTIONS FROM
        THE EXCHANGE AGENT.

        Management and Operations of CRC After the Merger

             It is contemplated that after the Merger, CRC will continue
        to operate as a separate entity and that  Thermo does not
        presently intend to change the domicile, name or operations of
        CRC.  Thermo has advised CRC, however, that James B. Morrison,
        Richard H. Levine, Martin R. Adams, Buddy G. Beck and Robert V.
        Wells will be named as directors of CRC and that Marshall J.
        Armstrong, a Vice President of Thermo, will be named as Chairman
        of the Board of CRC.  Thermo currently intends that the existing
        officers of CRC will retain their offices after the Effective
        Date, but may appoint additional officers of CRC from time to
        time.  See "THERMO AND CRC MANAGEMENTS -- Executive Officers and
        Directors of CRC." 

        Effective Date

             The Merger shall become effective upon the later of the date
        of filing of a Certificate of Merger with the Secretary of State
        of the State of Delaware pursuant to Section 252 of the Delaware
        General Corporation Law and the date of filing of Articles of
        Merger with the Secretary of State of the State of Florida
        pursuant to Section 607.1107 of the Florida Business Corporation
        Act (the "Effective Date").  It is currently expected that the
        Effective Date will be on or about February 23, 1995.

             The respective obligations of Thermo, Acquisition Corp. and
        CRC under the Merger Agreement are subject to a number of
        conditions specified in the Merger Agreement.  Unless all such
        conditions to the obligations have been satisfied or waived by
        the party to the Merger Agreement benefiting from such

        Conduct of CRC's Business Pending the Merger

             CRC has agreed to carry on its business prior to the
        Effective Date in substantially the same manner as prior to the
        date of the Merger Agreement.  CRC has further agreed, prior to
        the Effective Date to (i) maintain all of its properties in
        customary repair, order and condition, reasonable wear and use
        and damage by unavoidable casualty excepted, and take all steps
        reasonably necessary to maintain its intangibles, (ii) maintain

        belonging to CRC, and (vii) promptly advise Thermo of any written
        objection to the Merger from a shareholder of CRC. 

             Subject to certain exceptions, CRC has also agreed that
        prior to the Effective Date, it will not engage in certain types
        of transactions without the prior written consent of Thermo,
        including, among other transactions, (i) making any changes in
        its management or granting any increase in compensation or bonus
        to any member of management or, except in the ordinary course of
        business consistent with past practice, entering into or altering
        or amending any employment or consulting contract or similar
        agreement, (ii) entering into any transaction or contract with
        any of its shareholders, officers, management, directors or
        employees or their family members, (iii) creating, incurring,

        any other person, firm, association, corporation or other
        business organization, (vii) issuing any shares of capital stock
        except pursuant to existing stock option agreements, or entering
        into any commitment or agreement, or granting any option, warrant
        or right, calling for the issuance of any shares of stock, or
        creating or issuing any securities convertible into any such
        shares or convertible into securities in turn so convertible,
        (viii) declaring any dividends on or in respect of shares of

        transactions contemplated by the Merger Agreement as a pooling-
        of-interests for accounting purposes, (xiv) taking any action
        which would prevent the Merger from qualifying as a tax-free

        sale, or sale of Thermo Common Stock except for the distribution

        Noncompetition Agreement

             In satisfaction of a condition to Thermo's obligation to
        consummate the Merger, Thomas J. Coleman will enter into a
        noncompetition agreement, effective upon consummation of the
        Merger, providing that for a period of three years after the
        Effective Date, Mr. Coleman will not, directly or indirectly,
        engage in any activity in the United States relating to the
        development, marketing or sale of any product or service which
        competes with any product or service currently sold by CRC,
        currently under development by CRC, or which CRC may offer or
        develop in the future.  Subject to certain limitations, Mr.
        Coleman may establish or participate in a systems engineering
        business that, in the opinion of CRC, is not in conflict with the
        best interests of CRC during the term of the noncompetition
        agreement.  The noncompetition agreement further provides that
        for a period of three years after the Effective Date, Mr. Coleman
        will not, directly or indirectly, hire, solicit, interfere with
        or endeavor to entice away any officer or employee of CRC or in
        any matter encourage any officer or employee of CRC to leave its
        employ; except that he may solicit Harriett C. Coleman, Michael
        Coleman, Benjamin Patz and Cynthia Patz to leave the employ of
        CRC.  

        Accounting Treatment

             The Merger is expected to meet all of the conditions for
        pooling-of-interests accounting.  It is a condition to the
        obligation of Thermo to consummate the Merger that Thermo shall
        have received an opinion from Thomas, Beck & Zurcher, P.A., CRC's
        independent accountants, to the effect that Thomas, Beck &
        Zurcher, P.A. is not aware of any fact concerning CRC that would
        preclude Thermo from accounting for the merger as a
        pooling-of-interests.

        Regulatory Approvals

             The Merger is subject to the requirements of the Antitrust
        Improvements Act and the regulations thereunder (the "Antitrust
        Improvements Act"), which provide that certain acquisition
        transactions (including the Merger) may not be consummated until
        certain information has been furnished to the Antitrust Division
        of the Department of Justice (the "Antitrust Division") and the
        Federal Trade Commission (the "FTC"), and certain waiting period
        requirements have been satisfied.  Thermo and CRC have filed the
        required information and material with the Antitrust Division and
        the FTC and the applicable waiting period terminated on January
        __, 1995.  Termination of the waiting period does not preclude
        the Antitrust Division, the FTC or any other party from
        challenging or seeking to delay or enjoin the Merger on antitrust
        or other grounds.  There can be no assurance that such a
        challenge, if made, would not be successful; however, neither
        Thermo nor CRC believes that the Merger will violate the
                                       41
PAGE
<PAGE>





        antitrust laws.  Any such action taken or threatened prior to the
        consummation of the Merger could relieve Thermo or CRC of their
        respective obligations to consummate the Merger.  

        Resale of Thermo Common Stock Received in the Merger; Affiliates

             Certain officers, directors and principal shareholders of
        CRC have entered into an agreement with CRC and with Thermo, in
        the form attached as Exhibit C to the Merger Agreement, pursuant
        to which they have agreed that, until such time as financial
        results covering at least thirty days of combined operations of
        CRC and Thermo have been published by Thermo, they will not sell,
        transfer or otherwise dispose of, or offer or agree to sell,
        transfer or otherwise dispose of any shares of Thermo Common
        Stock received by them pursuant to the Merger or any securities
        which may be paid as a dividend or otherwise distributed thereon
        or with respect thereto or issued or delivered in exchange or
        substitution therefor.  Legends restricting the transfer of such
        shares of Thermo Common Stock will be placed on all certificates
        representing such shares.  The purpose of this restrictions is to
        comply with conditions necessary for the Merger to be treated as
        a "pooling-of-interests" for accounting and financial reporting
        purposes.

             The shares of Thermo Common Stock to be issued in the Merger
        to the CRC shareholders pursuant to the Merger Agreement have
        been registered under the Securities Act, thereby allowing such
        shares to be freely traded without restriction by persons who are
        not deemed to be "affiliates," as that term is defined in the
        Securities Act, of Thermo or of CRC.  Certain officers, directors
        and principal shareholders of CRC may be deemed to be affiliates
        of CRC and thus "underwriters" within the meaning of Rule 145
        under the Securities Act.  Such persons will not be able to
        resell the Thermo Common Stock received by them in the Merger
        except pursuant to an effective registration statement under the
        Securities Act or pursuant to another applicable exemption
        therefrom.  All persons who may be deemed to be affiliates should
        carefully consider the limitations imposed by Rules 144 and 145
        under the Securities Act prior to effecting resales of the Thermo
        Common Stock.  See "CERTAIN FEDERAL INCOME TAX CONSEQUENCES."

        Termination, Amendments and Expenses

             The Merger Agreement may be terminated and the Merger
        contemplated thereby abandoned at any time prior to the
        consummation of the Merger by the mutual consent of Thermo and
        CRC.  The Merger Agreement may be terminated by Thermo or CRC
        acting alone if any of the conditions precedent to their
        obligations to consummate the Merger have not been met or waived.
        The Merger Agreement may also be terminated by Thermo or CRC
        acting alone, (i) in the event any litigation, either
        administrative or judicial, shall be pending or threatened
        against Thermo or CRC which presents a reasonable probability,
        supported by an opinion of counsel of the party electing to
                                       42
PAGE
<PAGE>





        terminate, that the Merger Agreement may be enjoined or (ii) if
        through no fault of any party to the Merger Agreement, the Merger
        has not been consummated by the close of business on February 28,
        1995.

             In the event that the Merger is terminated in accordance
        with the terms of the Merger Agreement, each party will be
        responsible for the costs incurred by it in connection with the
        transactions contemplated by the Merger Agreement.

        Certain Effects of the Merger

             Upon consummation of the Merger the present holders of CRC
        Common Stock (other than holders of shares with respect to which
        statutory dissenters' rights are perfected) will receive an
        equity interest in a large diversified company of which CRC will
        be a small part.  Thermo will continue to be subject to the
        periodic reporting requirements of the Exchange Act and, under
        current regulations promulgated thereunder, will continue to
        furnish information to the Commission so long as any securities
        of Thermo are listed on a national securities exchange or held of
        record by at least 300 holders.  See "AVAILABLE INFORMATION" AND
        "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE."  It is a
        condition to CRC's and Thermo's obligations under the Merger
        Agreement that the shares of Thermo Common Stock to be issued in
        connection with the Merger be listed on the New York Common Stock
        Exchange, or approved for listing on the New York Common Stock
        Exchange subject to official notice of issuance.  See "THE MERGER
        -- Conditions to Consummation of the Merger."

             The CRC Common Stock is not presently, and will not be after
        the Merger, listed or traded in any established market.

             It is expected that, following the Merger, the business and
        operations of CRC will be continued by Thermo in substantially
        the same manner as it has been operating.  However, Thermo will
        continue to evaluate CRC's business and operations following the
        Merger and will make such changes as are deemed appropriate.

             If the Merger is consummated, the holders of CRC Common
        stock (other than holders of shares with respect to which
        statutory dissenters' rights are perfected) will exchange their
        shares of CRC Common Stock for Thermo Common Stock.  The rights
        of CRC shareholders, which are presently governed by Florida law
        and by the Articles of Incorporation and By-laws of CRC, will be
        governed by Delaware law and the Amended and Restated Certificate
        of Incorporation and By-laws of Thermo.  Certain differences in
        the rights of CRC shareholders will arise as a result of this
        change in governing law as well as from distinctions between the
        Articles of Incorporation and By-laws of CRC and the Amended and
        Restated Certificate of Incorporation and By-laws of Thermo.  See
        "THE MERGER -- Certain Effects of the Merger" and "COMPARISON OF
        RIGHTS OF HOLDERS OF THERMO COMMON STOCK AND CRC COMMON STOCK."

        Interests of Certain Persons in the Merger

             Shareholders should be aware that certain officers and
        directors of CRC have interests, described below, which may
        present them with potential conflicts of interest in connection
        with the transaction.  Management of CRC, including Thomas J.
        Coleman, the sole member of the Board of Directors of CRC, is
        aware of the conflicts described below and considered them in
        addition to the other matters described under "BACKGROUND OF THE
        MERGER AND RELATED MATTERS -- CRC'S Reasons for the Merger."

             Upon consummation of the Merger, Mr. Thomas J. Coleman, the
        sole member of CRC's Board of Directors, will resign, and Thermo
        intends to name James B. Morrison, Richard H. Levine, Martin R.
        Adams, Buddy G. Beck and Robert V. Wells to CRC's Board and
        Marshall J. Armstrong, a Vice President of Thermo, as Chairman of
        the Board.  Thermo currently intends that the existing officers
        of CRC will retain their offices after the Effective Date, but
        may appoint additional officers of CRC from time to time.  

             Certain members of CRC's management, including Messrs.
        Morrison, Levine, Adams, Beck and Wells, have written employment
        or compensation agreements with CRC.  These agreements will
        remain in force through their expiration but will not be renewed;
        thereafter, each member of CRC's management will serve CRC as an
        employee-at-will.  Thermo does not presently intend to change the
        base cash compensation of CRC's management.  However, Thermo does
        intend to amend CRC's management bonus program to award bonuses
        to CRC's management and to certain other key employees that are
        related to CRC's net income rather than to CRC's revenue.
        Certain members of CRC's management, including Messrs. Morrison,
        Levine, Adams, Beck and Wells, have the contractual right to
        receive grants of options to purchase additional shares of CRC
        Common Stock.  As a result of the Merger, these rights will be
        converted into the right to receive grants of options to purchase
        an economically equivalent number of shares of Thermo Common
        Stock.  As of the date of this Proxy Statement/Prospectus,
        whether the changes described above will have the effect of
        enhancing or reducing the overall compensation of CRC's
        management cannot be determined.  See "THERMO AND CRC MANAGEMENTS
        -- Executive Officers and Directors of CRC."

             It is not anticipated that the directors of CRC will receive
        separate compensation for serving in such capacities.

             See "APPROVAL OF THE COLEMAN LABORATORIES TRANSACTION."

        Certain Employee Benefits Matters

             Shares of CRC Common Stock held by the KSOP on the Effective
        Date will be automatically converted into shares of Thermo Common
        Stock.  See "THE MERGER -- Structure and Terms of the Merger" and
        "-- Indemnification of Thermo; Escrow."  Thermo currently intends
        to maintain the KSOP through December 31, 1996.  Continuation of
                                       44

        the plan after that date, however, will depend on the results of
        statutory discrimination tests that must be made at that time.
        Thermo intends to amend both the 401(k) feature of the KSOP (the
        "401(k) Plan") and the employee stock ownership feature of the
        KSOP (the "ESOP") shortly after the consummation of the Merger.  

             As amended, the 401(k) Plan would provide an additional
        option to reallocate up to 20% of a participant's account balance
        as of the Effective Date in a fund that would purchase shares of
        Thermo Common Stock (the "Thermo Stock Fund") and to invest up to
        20% of a participant's future contributions in the Thermo Stock
        Fund.  Subject to the restrictions on resale by certain officers,
        directors and principal shareholders of CRC (see "THE MERGER --
        Resale of Thermo Common Stock Received in the Merger;
        Affiliates"), a participant in the 401(k) Plan may direct the
        trustee of the plan to sell shares of Thermo Common Stock held in
        such participant's 401(k) Plan account as a result of the Merger
        on a quarterly basis and the proceeds of such sales may be
        reinvested in accordance with the participant's then-current
        investment election.

             As amended, the ESOP would provide that participants may
        continue to direct the investment of that portion of their
        account balances existing on the Effective Date and over which
        they have investment discretion in accordance with the current
        terms of the ESOP.  However, any contributions to the ESOP after
        the Effective Date will be made in shares of Thermo Common Stock
        and participants generally will not be permitted to direct the
        investment of such contributions or to sell shares of Thermo
        Common Stock in such participants' accounts as a result of the
        Merger.  Employees who have achieved age 55 and who have
        participated in the ESOP for at least 10 years may, however,
        direct the investment of their ESOP balances in accordance with
        statutory requirements to allow diversification of retirement
        plan holdings.

             Thermo also currently intends to maintain the CRC Money
        Purchase Plan through December 31, 1996.  Again, continuation of
        this plan after that date will depend on the results of statutory
        discrimination tests that must be made at that time.  Thermo
        intends to amend the plan shortly after the consummation of the
        Merger to provide (i) an additional option to invest up to 10% of
        a participant's balances as of the Effective Date and future
        employer contributions in the Thermo Stock Fund and (ii) for
        investment elections to be made quarterly and separately from
        elections made with respect to the KSOP.

             Thermo currently intends to maintain all material CRC
        employee benefit plans or programs (including CRC's annual bonus
        program, tuition reimbursement program and non-interest-bearing
        loan program for the purchase of personal computers by employees)
        without significant modification after the Effective Date, except
        as described above and except that CRC's contract stock options
        and CRC's annual stock option bonus program would be amended as
                                       45

        described on Schedule 4.7 to the Merger Agreement.  However,
        Thermo has reserved the right to modify or terminate any such
        benefit plans or programs, including those described above, at
        any time or from time to time after the Effective Date. 

             All otherwise eligible CRC employees will be entitled to
        participate in any employee stock purchase plan adopted from time
        to time by Thermo, in accordance with the terms thereof.  Except
        as may be otherwise required by applicable law, Thermo will give
        CRC employees credit for service with CRC when such employees
        become eligible for participation in any of Thermo's benefit
        plans which have vesting or length of service requirements.


                        RIGHTS OF DISSENTING SHAREHOLDERS

             The rights of holders of shares of CRC Common Stock who
        object to the Merger are governed by Section 607.1320 of the
        Florida Law ("Section 607.1320").  The following summary of
        applicable provisions of Section 607.1320 is not intended to be a
        complete statement of such provisions and is qualified in its
        entirety by reference to the full text of Section 607.1320, which
        is set forth as APPENDIX IV.   

             If the Merger is consummated, any CRC shareholder complying
        with the steps set forth in the provisions of Section 607.1320 is
        entitled to have the "fair value" of his or her shares of CRC
        Common Stock at the Effective Date (exclusive of any element of
        value arising from the accomplishment or expectation of the
        Merger) judicially determined and paid to him or her as a
        dissenting shareholder under the Florida Law in lieu of receiving
        shares of Thermo Common Stock.

             In order for any holder of CRC Common Stock to perfect his
        or her right to appraisal, such shareholder must satisfy each of
        the following conditions:

                  (i)  Such shareholder must deliver to CRC before the
             vote on the Merger Agreement is taken at the Special Meeting
             written notice of such shareholder's intent to demand
             payment for such holder's shares of CRC Common Stock; and

                  (ii) such shareholder must not vote such shares of CRC
             Common Stock in favor of the Merger Agreement.  NEITHER
             VOTING AGAINST, WHETHER IN PERSON OR BY PROXY, THE MERGER
             AGREEMENT NOR FAILING TO VOTE IN FAVOR OF THE MERGER
             AGREEMENT WILL CONSTITUTE THE REQUISITE NOTICE OF INTENT TO
             DEMAND PAYMENT.  Failure to vote on the Merger Agreement
             will not constitute a waiver of dissenters' rights, provided
             that a written notice is properly and timely filed.

             A SHAREHOLDER WHO ELECTS TO EXERCISE DISSENTER RIGHTS SHOULD
        MAIL OR DELIVER HIS WRITTEN NOTICE TO COLEMAN RESEARCH

                                       46

        CORPORATION, 201 SOUTH ORANGE AVENUE, SUITE 1300, ORLANDO,
        FLORIDA  32801, ATTENTION: SECRETARY.  

             If the Merger Agreement is adopted and approved by the
        shareholders of CRC at the Special Meeting, then CRC is required,
        within ten days after the date of the Special Meeting, to provide
        written notice of such adoption and approval to each CRC
        shareholder who timely and properly filed a notice of intent to
        demand payment for such holder's shares of CRC Common Stock.
        Within 20 days after CRC gives such notice, any CRC shareholder
        who elects to exercise dissenters' rights must file with CRC a
        notice of such election, which notice must include such holder's
        name and address, the number and classes of shares as to which
        such holder dissents, and a demand for payment of the fair market
        value of such holder's shares of CRC Common Stock.  A CRC
        shareholder who fails to file such an election with such 20-day
        period will have waived such holder's dissenter's rights, and
        will thereafter only have the right to receive shares of Thermo
        Common Stock (and cash in lieu of fractional shares) under the
        terms of the Merger Agreement.  Any CRC shareholder who elects to
        dissent will be required to deposit with CRC the certificates
        representing the shares of CRC Common Stock as to which such
        holder dissents simultaneously with the filing of the election to
        dissent.

             Within ten days after the expiration of the period in which
        shareholders may file their notices of election to dissent, or
        within ten days after the Merger is effected, whichever is later,
        CRC will make a written offer to each dissenting shareholder who
        followed the procedures set forth in Section 607.1320 to pay an
        amount CRC estimates to be the fair value for such shares.  If
        the shareholder accepts the offer within 30 days of its making,
        payment will be made within 90 days after the making of the offer
        or the Effective Date, whichever is later.

             If CRC fails to make such an offer within the 30-day period,
        or if it makes such an offer and any shareholder fails to accept
        it within 30 days of its making, then CRC must, within 30 days
        after receipt of written notice of election to dissent from any
        dissenting shareholder given within 60 days after the Effective
        Date, file an action in any court of competent jurisdiction
        requesting that the fair value of such shares be determined.  If
        CRC fails to institute such a proceeding, any dissenting
        shareholder may do so in the name of CRC.  All dissenting
        shareholders, other than those who have agreed with CRC as to the
        fair value of their shares, will be made party to such
        proceeding, and all such parties will be entitled to judgment
        against CRC for the amount of the fair value of their shares of
        CRC Common Stock.

             CRC shareholders considering seeking appraisal should bear
        in mind that the fair value of their shares determined under
        Section 607.1320 could be more than, the same as or less than the
        value of the consideration they would receive pursuant to the
                                       47

<PAGE>





        Merger if they did not seek appraisal of their shares and that a
        significant period of time could elapse before the court
        determines such fair value.  The cost of the appraisal proceeding
        may be charged against CRC or may be determined by the court and
        taxed against the parties as the court deems equitable under the
        circumstances.

             Any CRC shareholder who has duly demanded appraisal in
        compliance with Section 607.1320 will not, after the Effective
        Date, be entitled to vote, for any purpose, the shares of CRC
        Common Stock subject to such demand or to receive payment of
        dividends or other distributions payable to shareholders of
        record at a date prior to the Effective Date.



                    COMPARISON OF RIGHTS OF HOLDERS OF THERMO
                        COMMON STOCK AND CRC COMMON STOCK

             The rights of the CRC shareholders are governed by the laws
        of the State of Florida, including the Florida Business
        Corporation Act (the "Florida Law"), and by CRC's Articles of
        Incorporation, as amended (the "CRC Articles"), and CRC's
        By-Laws, as amended (the "CRC By-Laws").  Upon consummation of
        the Merger, the CRC shareholders will become stockholders of
        Thermo and their rights as stockholders and the internal affairs
        of Thermo will be governed by the laws of the State of Delaware,
        including the General Corporation Law of the State of Delaware
        (the "Delaware Law"), and by Thermo's Amended and Restated
        Certificate of Incorporation (the "Thermo Certificate"), and
        Thermo's By-Laws (the "Thermo By-Laws"), which differ in certain
        material respects from Florida Law, the CRC Articles and the CRC
        By-Laws.  The following is a summary of certain differences
        between the rights of CRC shareholders compared with those of
        Thermo stockholders.

             The following summary does not purport to be a complete
        description of the rights of shareholders of CRC or the rights of
        stockholders of Thermo or a comprehensive comparison of such
        rights, and is qualified in its entirety by reference to the
        governing law, to the Thermo Certificate and By-Laws and to the
        CRC Articles and By-Laws, to which shareholders are referred.
        For more information regarding reviewing or obtaining a copy of
        either company's charter documents or by-laws, see "AVAILABLE
        INFORMATION."   

        Amendment of Charter and By-Laws

             Section 242 of the Delaware Law provides that stockholders
        may amend their corporation's certificate of incorporation if a
        majority of the outstanding stock entitled to vote thereon, and a
        majority of the outstanding stock of each class entitled to vote
        thereon as a class, has been voted in favor of the amendment.
        The Delaware Law also provides that after a corporation has
                                       48
PAGE
<PAGE>





        received any payment for its stock, the power to adopt, amend or
        repeal by-laws resides with the stockholders entitled to vote.  A
        corporation may, however, grant to its board of directors in its
        certificate of incorporation concurrent power to adopt, amend or
        repeal by-laws.

             Under Florida Law, shareholders may amend their articles of
        incorporation if the amendment is approved by (i) a majority of
        the votes entitled to be cast on the amendment by any voting
        group with respect to which the amendment would create dissenter
        rights; and (ii) the votes required for voting groups and
        multiple voting groups by every other voting group entitled to
        vote on the amendment.  In addition, a corporation's board of
        directors may amend or repeal the corporation's by-laws unless
        the articles of incorporation or by-laws provide otherwise.

             Thermo.  Thermo's Certificate expressly provides that the
        board of directors is authorized to adopt, repeal, alter, amend
        or rescind Thermo's By-Laws.

             CRC.  CRC's Articles empower the board of directors to
        adopt, alter, amend or repeal CRC's By-Laws.

        Certain Actions Requiring Supermajority Votes

             Both Delaware Law and Florida Law set certain minimum voting
        requirements for selected corporate actions that may be changed
        by appropriate provisions contained in a corporation's
        certificate of incorporation and/or by-laws.

             Thermo.  Under Thermo's Certificate, the votes of the
        holders of 66-2/3% of the shares of stock then entitled to vote
        for the election of directors of the Corporation ("Voting Stock")
        are required for the following actions: (i) the merger of Thermo
        into another corporation or other business entity, (ii) the
        merger of another corporation or other business entity into
        Thermo, (iii) the consolidation of Thermo with another
        corporation or other business entity, (iv) the sale, exchange,
        lease or other transfer all or substantially all of Thermo's
        assets to any other person, (v) dissolution, (vi) amendments to
        Thermo's Certificate and (vii) amendments to Thermo's By-laws or
        ratification of the amendment thereof by Thermo's Board of
        Directors.

             Thermo's Certificate further provides that, in the event
        that any corporation or other business entity, together with all
        affiliates thereof, owns beneficially, directly or indirectly,
        25% or more of the outstanding Thermo Common Stock (a "Related
        Entity"), the vote of the holders of 85% of all shares of the
        Voting Stock exclusive of all shares the Voting Stock held by
        Related Entities shall be required for any of the following
        actions: (i) the merger of Thermo into a Related Entity, (ii) the
        merger of a Related Entity into Thermo, (iii) the consolidation
        of Thermo with a Related Entity, (iv) the sale, exchange, lease
                                       49
PAGE
<PAGE>





        or other transfer all or substantially all of Thermo's assets to
        a Related Entity, (v) the acquisition of an interest in a Related
        Entity through the issuance of Thermo's stock, the exchange of
        Thermo's assets or otherwise, (vi) the entering into of any
        agreement to take any of the actions contemplated by the
        preceding clauses (i) through (v), (vii) the further amendment of
        Thermo's Certificate relating to the actions contemplated by the
        preceding clauses (i) through (vi) or amendment of Thermo's
        By-Laws or the ratification of the amendment thereof by Thermo's
        Board of Directors in such regard.  For these purposes, Thermo's
        Certificate defines an "affiliate" of any entity as any person
        which controls, is controlled by or is under common control with
        that entity, and any officer or director of that entity or any
        other affiliate thereof and any person which owns beneficially,
        directly or indirectly, 10% or more of any class of equity
        securities of that entity or any other affiliate thereof.

             Thermo's Certificate also contains a requirement that if any
        person acquires by tender offer more than 50% of the outstanding
        Thermo Common Stock and Thermo's Board of Directors does not
        recommend that the tender offer be accepted, each remaining
        Thermo stockholder will have the right to have his shares
        redeemed by Thermo at a price generally equal to the tender offer
        price.

             CRC.  Neither the CRC Articles nor the CRC By-Laws require
        the vote of the holders of more than a majority of the CRC Common
        Stock to approve any corporate action.

        Board of Directors

             Under both Delaware Law and Florida Law, a corporation's
        board of directors must consist of one or more individuals, with
        the number fixed by (or in the manner provided in) the
        corporation's by-laws or its certificate of incorporation or
        articles, respectively.

             Thermo.  Under Thermo's By-Laws, Thermo's Board shall
        consist of between eight and twelve directors.  Thermo's By-Laws
        state that the directors will be divided into three classes, as
        nearly as equal in number as possible, with each class of
        director being elected to serve for three years.  Currently,
        Thermo's Board has set the number of directors at ten.  The
        provisions for classification of the Board, which are designed to
        provide continuity and longer-term participation on the Board,
        would prevent stockholders holding a majority of shares of Thermo
        Common Stock outstanding from electing a majority of the
        directors of Thermo at any one annual meeting of stockholders.
        Such provisions may discourage or render more difficult certain
        transactions, whether or not beneficial to public stockholders,
        and could discourage certain types of tactics which involve an
        actual or threatened change of control of Thermo because at least
        two annual meetings of stockholders could be required to replace
        a majority of the Board.

             CRC.  The CRC By-Laws state that the Board shall consist of
        one director and that such director shall serve a term of one
        year.  

        Removal of Directors

             Delaware Law permits any director or the entire board of
        directors to be removed, with or without cause, by the vote of
        the holders of a majority of the shares entitled to vote.
        Directors of a corporation with a classified board of directors,
        however, such as Thermo, can be removed only for cause unless the
        certificate of incorporation provides otherwise.  

             Under Florida Law, the shareholders may remove one or more
        directors with or without cause unless the articles of
        incorporation provide otherwise.  However, if a director is
        elected by a voting group of shareholders, only the shareholders
        of that voting group may participate in the vote to remove him.  

             Thermo.  Neither Thermo's Certificate nor its By-Laws
        specifically address the requirements for the removal of
        directors generally.  Therefore, a Thermo director may be removed
        by stockholders only for cause.  Any vacancy on the board
        resulting from any increase in the authorized number of directors
        may be filled only by a majority of the directors then in office,
        provided that a quorum is present.  Any other vacancy on the
        board may be filled only by a majority of the directors then in
        office, even if less than a quorum, or by a sole remaining
        director.

             CRC.  CRC's By-Laws provide that any director may be removed
        from office, either with or without cause, at any time.  Any
        vacancy occurring in the board of directors may be filled by the
        affirmative vote of a majority of the remaining directors then in
        office or by the CRC shareholders.

        Special Meeting of the Stockholders

             Under both Delaware Law and Florida Law, special meetings of
        stockholders may be called by the board of directors and by such
        other person or persons authorized to do so by the corporation's
        certificate or articles of incorporation or by-laws.
        Additionally, under Delaware Law, if an annual meeting is not
        held within 30 days of the date designated for such a meeting, or
        is not held for a period of 13 months after the last annual
        meeting, the Delaware Court of Chancery may summarily order a
        meeting to be held upon the application of any stockholder or
        director.

             Under Florida Law, holders of at least 10%, unless a greater
        percentage not to exceed 50% is required by the articles of
        incorporation, of all the votes entitled to be cast on any issue
        proposed to be considered at the proposed special meeting who
                                       51
PAGE
<PAGE>





        sign, date, and deliver to the corporation one or more written
        demands for the meeting describing the purpose or purposes for
        which it is to be held may call a special meeting.  Additionally,
        the circuit court of the county where a corporation's principal
        office is located may order (i) an annual meeting on application
        of any shareholder entitled to vote in an annual meeting if an
        annual meeting has not been held within any 13-month period; or
        (ii) a special meeting on application of a shareholder who signed
        a demand for a special meeting if (a) notice of the special
        meeting was not given within 60 days after the date the demand
        was delivered to the corporation's secretary; or (b) the special
        meeting was not held in accordance with the notice.

             Thermo.  Pursuant to Thermo's By-Laws, special meetings of
        the stockholders may be called by the President and shall be
        called by the President, Secretary or an Assistant Secretary when
        directed to do so by the Board.

             CRC.  Under CRC's By-Laws, special meetings of the
        shareholders may be called by the Chairman of the Board, the
        Board of Directors, the Chief Executive Officer, the President or
        on call signed by one or more shareholders holding an aggregate
        of not less than 10% of the outstanding shares entitled to vote
        at the meeting.

        Actions by Stockholders Without a Meeting

             Unless a corporation's certificate of incorporation or
        articles provide otherwise, Delaware Law and Florida Law allow
        any action required to be taken, or which may be taken, at an
        annual or special meeting of stockholders to be taken without
        prior notice and without a vote so long as the written consent of
        not less than the minimum number of votes that would be necessary
        to authorize or take such action at a meeting at which all shares
        entitled to vote thereon were present and voted is delivered to
        the corporation.

             Thermo.  Neither Thermo's Certificate nor its By-Laws
        address the issue relating to actions by shareholders without a
        meeting.  However, the rules of the New York Stock Exchange, on
        which the Thermo Common Stock is listed for trading, generally
        prohibit listed corporations from taking actions by written
        consent.

             CRC.  The CRC By-Laws provide that any action required or
        permitted to be taken by the shareholders may be taken without a
        meeting if such action is approved by the minimum number of votes
        that would be necessary to authorize or take the action at a
        meeting at which such shareholders were present and voted.  In
        order to be effective, such action must be evidenced by one or
        more written consents describing the action, dated and signed by
        the shareholders, and delivered to CRC within 60 days of the
        earliest consent.  Shareholders who did not consent to the action

                                       52
PAGE
<PAGE>





        taken must receive notice of such action within 10 days after the
        receipt of the written consent.

        Cumulative Voting

             Under Delaware Law, cumulative voting in the election of
        directors is available only if specifically provided for in a
        corporation's certificate of incorporation.  Under Florida Law,
        the articles of incorporation of a corporation may provide for
        cumulative voting in the election of directors.  Neither Thermo's
        Certificate nor CRC's Articles provide for cumulative voting.

        Vote Required for Certain Mergers and Consolidations

             Delaware Law insofar as it relates to mergers and other
        corporate reorganizations does not differ substantially from
        Florida Law.  Both Florida Law and Delaware Law provide for a
        shareholder vote (except as indicated below) of both the
        acquiring and acquired corporation to approve mergers.  In
        addition, while both Florida Law and Delaware Law require a
        shareholder vote of the selling corporation for the sale by a
        corporation of all or substantially all of its assets, Florida
        Law requires such a vote only if the sale is not in the regular
        course of business.  Both Florida Law and Delaware Law provide
        for a shareholder vote to approve the dissolution of a
        corporation.  Yet, Florida Law requires the affirmative vote of a
        majority of the outstanding shares of both the acquiring and
        acquired corporation in share-for-share exchanges while Delaware
        Law does not provide this right.

             Both Florida Law and Delaware Law do not require a
        shareholder vote of the surviving corporation in a merger
        provided certain conditions are satisfied.  Florida Law requires
        that after the merger (i) the articles of incorporation of the
        surviving corporation will not differ from its articles before
        the merger (except for amendments authorized absent shareholder
        approval); and (ii) each shareholder of the surviving corporation
        whose shares were outstanding immediately prior to the effective
        date of the merger will hold the same number of shares, with
        identical designations, preferences, limitations, and relative
        rights, immediately after the merger.  Delaware Law does not
        require a shareholder vote of the surviving corporation in a
        merger if (i) the merger agreement does not amend the existing
        certificate of incorporation; (ii) each outstanding or treasury
        share of the surviving corporation before the merger is unchanged
        after the merger; and (iii) the number of shares to be issued by
        the surviving corporation in the merger does not exceed 20% of
        the shares outstanding immediately prior to such issuance.

             Both Florida Law and Delaware Law do not require a
        shareholder vote for certain "short-form mergers" between a
        parent company and its subsidiary.  Florida Law provides that the
        subsidiary be 80% owned by the parent while Delaware Law requires
        that the subsidiary be 90% owned by the parent.

        Class Vote for Certain Reorganizations

             Generally, neither Florida Law nor Delaware Law require
        class voting.  However, Florida Law provides that class or series
        voting as a separate voting group is required (i) on a plan of
        merger if the plan contains a provision which, if contained in a
        proposed amendment to the articles of incorporation, would
        entitle the class or series to vote as a separate voting group on
        the proposed amendment; or (ii) on a plan of share exchange if
        the shares of such class or series of shares are to be converted
        or exchanged under such plan or if the plan contains any
        provisions which, if contained in a proposed amendment to
        articles of incorporation, would entitle the class or series to
        vote as a separate voting group on the proposed amendment.
        Delaware Law requires class voting where the transaction involves
        an amendment to the certificate of incorporation which would
        increase or decrease the aggregate number of authorized shares of
        the class, increase or decrease the par value of the shares of
        the class, or alter or change the powers, preferences or special
        rights of the shares of the class so as to affect them adversely.

        Dissenter Rights

             Under both Florida Law and Delaware Law, a dissenting
        shareholder of a corporation participating in certain
        transactions, under varying circumstances, may receive cash in
        the amount of the fair value of his or her shares (as determined
        by a court) in lieu of the consideration otherwise receivable in
        any such transaction.  Unless the articles of incorporation
        provide otherwise, under both Florida Law and Delaware Law,
        dissenter rights are not available with respect to a plan of
        merger or share exchange or a proposed sale or exchange of
        property to holders of shares of any class or series which, on
        the record date fixed to determine the shareholders entitled to
        vote at the meeting of shareholders at which such action is to be
        acted upon or to consent to any such action without a meeting,
        were (i) registered on a national securities exchange or
        designated as a national market system security on an interdealer
        quotation system by the National Association of Securities
        Dealers, Inc., or (ii) held of record by not fewer than 2,000
        shareholders.  In addition, under Delaware Law, dissenter rights
        are not available for any shares of stock of the constituent
        corporation surviving a merger if the merger did not require
        shareholder approval of the surviving corporation.

             Florida Law also provides dissenter rights in connection
        with (i) sales of substantially all of a corporation's assets,
        (ii) amendments to the articles of incorporation that may
        adversely affect certain rights of preferences of shareholders
        and (ii) control-share acquisitions.  Delaware Law does not
        provide dissenter rights with respect to any sale of assets,
        reclassification of stock or amendment to the certificate of
        incorporation.

        Anti-Takeover Statutes

             Thermo.  Thermo is subject to Section 203 of the General
        Corporation Law of the State of Delaware ("Section 203"), which
        regulates large accumulations of shares, including those made by
        tender offers.  Section 203 may have the effect of significantly
        delaying a purchaser's ability to acquire the entire interest in
        Thermo if such acquisition is not approved by Thermo's Board of
        Directors.  In general, Section 203 prevents an "Interested
        Stockholder" (defined generally as a person with 15% or more of a
        corporation's outstanding voting stock) from engaging in a
        "Business Combination" (defined below) with a Delaware
        corporation for three years following the date such person became
        an Interested Stockholder.  For purposes of Section 203, the term
        "Business Combination" includes sales, or other dispositions to
        the Interested Stockholder (except proportionately with the
        corporation's other shareholders) of assets of the corporation or
        a subsidiary equal to 10% or more of the aggregate market value
        of the corporation's consolidated assets or its outstanding
        stock; the issuance or transfer by the corporation or a
        subsidiary of stock of the corporation or such subsidiary to the
        Interested Stockholder (except for transfers in a conversion or
        exchange or a pro rata distribution or certain other
        transactions, none of which increase the Interested Stockholder's
        proportionate ownership of any class or series of the
        corporation's or such subsidiary's stock); or receipt by the
        Interested Stockholder (except proportionately as a stockholder),
        directly or indirectly, of any loans, advances, guarantees,
        pledges or other financial benefits provided by or through the
        corporation or a subsidiary.  

             The three-year moratorium imposed on Business Combinations
        by Section 203 does not apply if:  (a) prior to the date on which
        such stockholder becomes an Interested Stockholder the Board of
        Directors approves either the Business Combination or the
        transaction which resulted in the person becoming an Interested
        Stockholder; (b) the Interested Stockholder owns 85% of the
        corporation's voting stock upon consummation of the transaction
        which made him or her an Interested Stockholder (excluding from
        the 85% calculation shares owned by directors who are also
        officers of the target corporation and shares held by employee
        stock plans which do not permit employees to decide
        confidentially whether to accept a tender or exchange offer); or
        (c) on or after the date such person becomes an Interested
        Stockholder, the Board approves the Business Combination and it
        is also approved at a stockholder meeting by holders of 66-2/3%
        of the voting stock not owned by the Interested Stockholder.

             Under Section 203, the restrictions described above do not
        apply if, among other things, the corporation's original
        certificate of incorporation contains a provision expressly
        electing not to be governed by Section 203.  Thermo's Certificate
        does not contain such a provision.  Thermo could, at its option,
                                       55
PAGE
<PAGE>





        exclude itself from the coverage of Section 203 by amending its
        Certificate or By-laws at any time to exempt itself from
        coverage; but a By-Law or charter amendment may not become
        effective for a period of 12 months after the amendment is
        adopted.  The restrictions described above do not apply to
        certain Business Combinations proposed by an Interested
        Stockholder following the announcement or notification of one of
        certain extraordinary transactions involving the corporation and
        a person who had not been an Interested Stockholder during the
        previous three years or who became an Interested Stockholder with
        the approval of a majority of the corporation's directors.

             Section 203 is currently under challenge in lawsuits arising
        out of ongoing takeover disputes, and it is not yet clear whether
        and to what extent its constitutionality will be upheld by the
        courts.  Although the United States District Court of Delaware
        has consistently upheld Section 203, the Delaware Supreme Court
        has not yet considered the issue.  Thermo believes that, so long
        as the enforceability of Section 203 is upheld, Section 203 will
        encourage any potential acquirer to negotiate with Thermo's Board
        of Directors prior to effecting any takeover attempt. Section 203
        also should have the effect of limiting the ability of a
        potential acquirer to make a two-tiered  bid in which all of
        Thermo's stockholders would not be treated equally.  Section 203
        should also discourage certain potential acquirers unwilling to
        comply with its provisions.  Shareholders should note that the
        application of Section 203 to Thermo will confer upon the Board
        the power to reject a proposed Business Combination, even though
        a potential acquirer may be offering a substantial premium for
        Thermo's shares over the then-current market price.

             CRC.  Section 607.0901 of Florida Law contains a provision
        generally similar to Section 203.  Section 607.0901 provides
        that, in addition to any affirmative vote required by Florida Law
        or the articles of incorporation, an affiliated transaction must
        be approved by the affirmative vote of the holders of two-thirds
        of the voting shares other than the shares beneficially owned by
        the interested shareholder (which is defined generally under
        Florida Law as a person with 10% or more of a corporation's
        outstanding voting shares).  The voting requirement does not
        apply if (i) the affiliated transaction has been approved by a
        majority of the disinterested directors; (ii) the corporation has
        not had more than 300 shareholders of record at any time during
        the three years preceding the announcement date; (iii) the
        interested shareholder has been the beneficial owner of at least
        80 percent of the corporation's outstanding voting shares for at
        least five years preceding the announcement date; (iv) the
        interested shareholder is the beneficial owner of at least 90
        percent of the outstanding voting shares of the corporation,
        exclusive of shares acquired directly from the corporation in a
        transaction not approved by a majority of the disinterested
        directors; (v) the corporation is an investment company
        registered under the Investment Company Act of 1940; or (vi) in
        the affiliated transaction, consideration is paid to the holders
                                       56
PAGE
<PAGE>





        of each class or series of voting shares pursuant to stringent
        valuation standards.

             Additionally, this section does not apply (i) to any
        corporation whose articles of incorporation, either as originally
        adopted or as amended prior to January 1, 1989, contain a
        provision expressly electing not to be governed by this section;
        (ii) to any corporation which adopts an amendment of its articles
        of incorporation or by-laws, approved by affirmative vote of the
        holders, other than interested shareholders, of a majority of the
        outstanding voting shares of the corporation expressly electing
        not to be governed by this section (although the amendment is not
        valid for 18 months); or (iii) to any affiliated transaction of
        the corporation with an interested shareholder of the corporation
        which became an interested shareholder inadvertently, if such
        interested shareholder, as soon as practicable, divests itself of
        a sufficient amount of the voting shares of the corporation so
        that it no longer is the beneficial owner of 10 percent or more
        of the outstanding shares of the corporation and would not at any
        time within the five-year period preceding the announcement date
        with respect to such affiliated transaction have been an
        interested shareholder but for such inadvertent acquisition.

        Stockholder Rights Agreement

             Thermo has declared a dividend of one right to purchase
        1/1,000 of a share of Series A
        Junior Participating Preferred Stock for each outstanding share
        of Thermo Common Stock, pursuant to the provisions of a Rights
        Agreement.  These rights, commonly referred to as a "poison
        pill," may have certain anti-takeover effects.  See "DESCRIPTION
        OF THERMO'S CAPITAL STOCK -- Preferred Share Purchase Rights;
        Series A Junior Participating Preferred Stock."  CRC does not
        have a comparable shareholder rights agreement.

        Preemptive Rights

             Thermo.  Delaware Law generally permits a Delaware
        corporation to provide its stockholders with the preemptive right
        to subscribe to capital stock or securities convertible into
        stock in its certificate of incorporation.  The Thermo
        Certificate does not provide for preemptive rights.

             CRC.  Florida Law generally provides that shareholders of a
        Florida corporation do not have a preemptive right to acquire
        unissued shares, except to the extent provided in the articles of
        incorporation.  The CRC Articles do not provide for preemptive
        rights.

        Dividends

             Thermo.  Delaware Law provides that a corporation, unless
        otherwise restricted by its certificate of incorporation, may
        declare and pay dividends out of surplus, or if no surplus
        exists, out of net profit for the fiscal year in which the
        dividend is declared or the preceding fiscal year (provided that
        the amount of capital of the corporation following the
        declaration and payment of the dividend is not less than the
        aggregate amount of the capital represented by the issued and
        outstanding shares of all classes having preference upon the
        distribution of assets).  Additionally, Delaware Law provides
        that, in general, a corporation may redeem or repurchase its
        shares only out of surplus.  

             CRC.  Florida Law provides that a corporation, unless
        otherwise restricted by its articles of incorporation, may
        authorize distributions unless after giving the distribution
        effect (i) the corporation would not be able to pay its debts as
        they become due in the usual course of business; or (ii) the
        corporation's total assets would be less than the sum of its
        total liabilities plus the amount that would be needed, if the
        corporation were to be dissolved at the time of the distribution,
        to satisfy the preferential rights upon dissolution of
        shareholders whose preferential rights are superior to those
        receiving the distribution.

        Limitation on Director's Liability; Indemnification

             In general, Delaware Law contains more extensive
        indemnification provisions than does Florida Law.  Under Delaware
        Law, the corporation may include in its certificate of
        incorporation a provision eliminating or limiting the personal
        liability of a director to the corporation or its stockholders
        for monetary damages for breach of fiduciary duty as a director
        under a broad range of circumstances.  Thermo's Certificate
        includes a provision which eliminates the directors' liability
        for monetary damages for a breach of the directors' duty of care
        to Thermo or its stockholders (the "Delaware Duty of Care
        Provision").  As a result of the Delaware Duty of Care Provision,
        no director of Thermo will be liable for monetary damages for
        negligence or gross negligence occurring after the Merger.  Each
        director will remain personally liable to Thermo for failure to
        act in good faith or to comply with his or her duty of loyalty to
        Thermo.  The directors will continue to be subject to equitable
        remedies, although such remedies in some circumstances may not be
        available as a practical matter.  In addition, under Delaware
        Law, each director will remain liable for engaging in a
        transaction from which such director derives an improper personal
        benefit or for engaging in intentional misconduct or a knowing
        violation of law.  Moreover, the Delaware Duty of Care Provision
        also will not limit directors' liability for violations of the
        federal securities laws.  With regard to directors who are also
        officers of Thermo, these persons would be insulated from
        liability only with respect to their conduct as directors and
        would not be insulated from liability for acts or omissions in
        their capacity as officers.

             Florida Law contains a provision similar to the Delaware
        Duty of Care Provision.  Under Section 607.0831 of Florida Law,
        directors are not personally liable to monetary damages to the
        corporation or any  other person, unless: (i) the director
        breached or failed to perform his duties as a director; and (ii)
        the director's breach of or failure to perform those duties
        constitutes: (a) a violation of the criminal law (unless the
        director had reasonable cause to believe his conduct was lawful
        or had no reasonable cause to believe his conduct was unlawful);
        (b) a transaction from which the director derived an improper
        personal benefit; (c) a circumstance under which the director
        would be liable for authorizing an unlawful distribution; (d) in
        a proceeding by or in the right of the corporation to procure a
        judgment in its favor or by or in the right of a  shareholder,
        conscious disregard for the best interests of the corporation, or
        willful misconduct; or (e) in a proceeding by or in the right of
        someone other than the corporation or a shareholder, recklessness
        or an act or omission which was committed in bad faith or with
        malicious purpose or in a manner exhibiting wanton and willful
        disregard of human rights, safety or property.

             Delaware Law authorizes the corporation to indemnify any
        person or party to any threatened, pending or completed action,
                                       59

<PAGE>





        suit or proceeding, other than an action by or in the right of
        the corporation, by reason of the fact that he or she was serving
        as a director, officer, employee or agent of the corporation or
        is or was serving at the request of the corporation at a like
        position of another corporation (the "Indemnitee") against
        expenses, judgments, fines and amounts paid in settlement
        actually and reasonably incurred in connection with such action
        if the Indemnitee acted in good faith and in a manner he or she
        reasonably believed to be in, or not opposed to, the best
        interests of the corporation (or, with respect to a criminal
        action, had no reasonable cause to believe his or her conduct was
        unlawful).  Florida Law contains a similar provision which
        authorizes the corporation to indemnify such person against
        liability incurred in connection with such action if he or she
        acted with the same requisite conduct. 

             Delaware Law also authorizes the corporation to indemnify
        such person in connection with any threatened, pending or
        completed action by or in the right of the corporation to procure
        a judgment in its favor against expenses actually and reasonably
        incurred by him or her in connection with the defense or
        settlement of such action if he or she acted with the requisite
        conduct. Florida Law authorizes the corporation to indemnify such
        person against expenses and amounts paid in settlement not
        exceeding, in the judgment of the board of directors, the
        estimated expense of litigating the proceeding to conclusion,
        actually and reasonably incurred in connection with the defense
        or settlement of such proceeding.  However, under Florida Law, to
        the extent an Indemnitee is successful on the merits or otherwise
        in defense of any proceeding (whether or not by or in the right
        of the corporation), or in defense of any claim, issue or matter
        therein, such Indemnitee shall be indemnified against expenses
        actually and reasonably incurred by him in connection therewith.

             Under both Florida Law and Delaware Law, the corporation
        must provide for indemnification on a case by case basis after a
        determination that the Indemnitee met the applicable standard of
        conduct.  Similarly, both laws provide that the determination is
        made in the first instance by the Board of Directors by a
        majority vote of a quorum consisting of directors who were not
        parties to such proceeding.  However, under Florida Law, if such
        a quorum is not obtainable, or, even if obtainable if the board
        of directors (including directors who are parties) so directs,
        the determination must be made by majority vote of a committee
        duly designated by the board of directors consisting solely of
        two or more directors not at the time parties to the proceeding,
        by independent legal counsel or finally by the shareholders.
        Under Delaware Law, if a quorum is not obtainable, or, even if
        obtainable a quorum of disinterested directors so directs, the
        determination must be made by independent legal counsel in a
        written opinion or by the stockholders.

             Furthermore, both Florida Law and Delaware Law provide that
        a corporation may make other or further indemnification or
                                       60
PAGE
<PAGE>





        advancement of expenses of any of its directors, officers,
        employees or agents under any by-law, agreement, vote of
        shareholders or disinterested directors, or otherwise both as to
        action in an official capacity and as to action in another
        capacity while holding such office.  Thermo has indemnification
        agreements with its directors and officers that provide for the
        maximum indemnification allowed by law.

             Thermo's Certificate takes advantage of the permissive
        Delaware indemnification laws and provides that: (i) Thermo is
        required to indemnify its officers and directors to the full
        extent permitted by law; and (ii) expenses incurred in defending
        a civil or criminal action, suit or proceeding may be paid by
        Thermo in advance of the final disposition of such action, suit
        or proceeding upon receipt of an undertaking by or on behalf of
        the director or officer to repay such amount if it shall
        ultimately be determined that he is not entitled to be
        indemnified by Thermo.

             CRC's Articles provide that the Board of Directors may
        indemnify current or former directors, officers, employees or
        agents of CRC, and any person serving, or who has served, at the
        request of CRC as a director, officer, employee or agent of
        another corporation, partnership, joint venture, trust or other
        enterprise to the full extent permitted by the laws of the State
        of Florida.  

        Loans to Officers and Employees

             Both Florida Law and Delaware Law provide that a corporation
        may make loans to, or guarantee the obligations of, or otherwise
        assist, its officers and other employees and those of its
        subsidiaries when such action, in the judgment of the
        corporation's board of directors, may reasonably be expected to
        benefit the corporation.  However, while Florida Law authorizes
        the corporation  to make a loan to, or guarantee the obligations
        of, or otherwise assist a director as well, Delaware Law applies
        only to those directors who also are officers or employees of the
        corporation or subsidiary.

        Voting By Ballot

             Under Delaware Law, each shareholder has the right to
        require a vote by written ballot for the election of directors at
        a shareholder meeting unless otherwise restricted as provided in
        the certificate of incorporation.

             There is no similar voting provision in the Florida Law.

        Inspection of  Shareholder Lists

             Florida Law provides that a shareholder may inspect the
        shareholders' list if (i) his demand is made in good faith and
        for a proper purpose; (ii) he describes with reasonable
                                       61
PAGE
<PAGE>





        particularity his purpose; and (iii) the shareholders' list is
        directly connected with his purpose.  Additionally, Florida Law
        provides to any shareholder an absolute right of inspection of
        the shareholders' list for a ten-day period preceding a
        shareholder meeting.  Delaware Law provides to any shareholder of
        record the right to inspect the shareholder list of the
        corporation for any purpose germane to the meeting for a ten-day
        period preceding a shareholder meeting.


                      DESCRIPTION OF THERMO'S CAPITAL STOCK

             The authorized capital stock of Thermo consists of
        175,000,000 shares of common stock, $1.00 par value per share
        (the "Thermo Common Stock"), 10,000 shares of Preferred Stock,
        $100.00 par value per share (the "Thermo Preferred Stock"), and
        40,000 shares of Series A Junior Participating Preferred Stock
        ("Series A Preferred Stock").  

        Common Stock

             Holders of Thermo Common Stock are entitled to one vote per
        share on all matters to be voted upon by the stockholders.  There
        are no cumulative voting rights.  The holders of Thermo Common
        Stock have no preemptive rights or rights to convert their Thermo
        Common Stock into any other securities.  The Thermo Common Stock
        is not subject to redemption.  Upon any liquidation, distribution
        or sale of assets, dissolution or winding up of Thermo, the
        holders of Thermo Common Stock are entitled to share pro rata in
        the assets of Thermo available for distribution after provision
        for the payment of creditors and subject to the preferential
        rights of any then outstanding Thermo Preferred Stock.  The
        outstanding shares of Thermo Common Stock are fully paid and
        nonassessable.  There are no restrictions on transferability
        contained in Thermo's Certificate or Thermo's By-Laws.  Subject
        to preferences that may be applicable to any outstanding shares
        of Thermo Preferred Stock, holders of Thermo Common Stock are
        entitled to receive ratably such dividends as may be declared by
        the Board of Directors out of funds legally available therefor.
        The Thermo Common Stock is listed on the New York Stock Exchange.

             As of December 15, 1994, there were outstanding 50,857,477
        shares of Thermo Common Stock.  Additional information concerning
        the rights of holders of Thermo Common Stock, including
        information with respect to the division of the Thermo Board of
        Directors into three classes, is set forth under "COMPARISON OF
        RIGHTS OF HOLDERS OF THERMO COMMON STOCK AND CRC COMMON STOCK."

        Preferred Stock

             The Board of Directors of Thermo may, without further action
        of Thermo's stockholders, issue up to 10,000 shares of Thermo
        Preferred Stock, in one or more classes and one or more series

        series.  The Board may similarly fix the rights and preferences
        of any class or series of Thermo Preferred Stock, including the
        dividend rights, dividend rates, conversion rights, voting
        rights, terms of redemption (including sinking fund provisions),
        maturity dates, redemption prices and liquidation preferences.
        The rights of the holders Thermo Common Stock will be subject to,
        and may be adversely affected by, the rights of holders of any
        Thermo Preferred Stock that may be issued in the future.
        Issuance of Thermo Preferred Stock could have the effect of
        making it more difficult for a third party to acquire, or of
        discouraging a third party from acquiring, a majority of the
        outstanding voting stock of Thermo.

        Preferred Share Purchase Rights; Series A Junior Participating
        Preferred Stock

             On May 4, 1988, Thermo's Board of Directors declared a
        dividend distribution of one right (a "Right") for each
        outstanding share of Thermo Common Stock to stockholders of

        CERTAIN DOCUMENTS BY REFERENCE" and "COMPARISON OF RIGHTS OF
        HOLDERS OF THERMO COMMON STOCK AND CRC COMMON STOCK."


                      RELATIONSHIP AND TRANSACTIONS BETWEEN
                                 THERMO AND CRC

             CRC and one of Thermo's subsidiaries, Thermedics Inc., have
        worked together since 1990.  CRC was a subcontractor to
        Thermedics in the development of a hand-held mine detection
        system for the U.S. Government, CRC providing the
        ground-penetrating radar and Thermedics providing the chemical
        detection systems.  Thermedics is currently a subcontractor to
        CRC in the development of a robotically controlled vehicle to
        allow remote chemical analysis of potentially contaminated
        facilities for the U.S. Department of Energy.  CRC and another
        Thermo subsidiary, Thermo Technology Ventures Inc., are teammates
        in support of Lockheed in the execution of the management and

                                 BUSINESS OF CRC

             CRC was formed in October 1980 to provide systems
        integration, systems engineering, and analytical services to both
        government and industry.  CRC currently has approximately 1,200
        employees.  CRC, headquartered in Orlando, Florida, has technical
        operations in Orlando, Florida; the Washington DC area;
        Huntsville, Alabama; Idaho Falls, Idaho; Charleston, South
        Carolina; and other locations throughout the United States.

             From its inception, with a core expertise in systems
        engineering, simulation and modeling, and analysis, CRC has built
        a broad-based expertise in defense and environmental systems
        engineering disciplines and in a growing number of other research
        areas.  CRC is currently providing, under a $218 million contract
        with the U.S. Army Space and Strategic Defense Command ("SSDC"),
        the assembly, integration and launch of 75 Department of Defense
        (DOD) payloads into suborbital flight.  These payloads are
        intended to serve as targets for Theater Missile Defense flight
        experiments.  Under this contract, CRC is responsible for the
        development and analysis of precision guidance and control
        systems, missile and ground support equipment design and
        integration, simulation, ground  testing, flight testing, and
        launch services (the "TMD Targets Project").

             CRC has developed a hand-held mine detection system for the
        detection of a wide variety of non-metallic anti-personnel and
        anti-vehicular mines.  This system is currently completing the
        prototype stage and extensive testing is expected to begin in the
        near future.  CRC has also integrated the electronics for a
        cellular telephone with a Global Positioning System (GPS)
        satellite receiver and a microprocessor to develop a mobile
        position locating device for the real-time tracking of vehicles.

             CRC performs Systems Engineering and Technical Assistance
        (SETA) contracts for DOD and other government agencies.  CRC's
        SETA contracts include those with the SSDC in Huntsville, Alabama
        to support the Theater High Altitude Area Defense (THAAD) Theater
        Missile Defense System (the "THAAD SETA Project"); the Naval
        Training Systems Center in Orlando, Florida to support Army and
        Navy training systems; and the Ballistic Missile Defense
        Organization (BMDO) in Washington DC to support strategic defense
        analysis.

             CRC provides systems engineering and systems integration
        support to the United States intelligence community.  CRC is
        actively involved in the design of signals collection
        architectures, as well as the development of mission management
        and message dissemination systems.  CRC is also developing
        signals identification analysis techniques for applications on
        workstations and super computers.

             CRC has a strong, multi-disciplinary capability in
        information technology, including local area and wide area
                                       64
PAGE
<PAGE>





        network and data base requirements analysis, design, and
        implementation.  CRC is developing virtual prototype environments
        for the "virtual" integration of large, complex systems in a
        laboratory environment.  CRC has significant involvement in
        Distributed Interactive Simulation technologies, whereby remote
        disparate elements can be linked in a real-time environment for
        enhanced training and strategy development.  CRC's simulation and
        modeling expertise covers virtually all contemporary software
        languages, including a significant capability in Ada.  In
        addition, CRC performs software engineering and analysis for the
        Drone Formation Control System at White Sands Missile range,
        controlling multiple aircraft and ground target commanded drones
        autonomously.

             Coleman Energy and Environmental Systems (CEES) was formed
        in 1991 as a division of CRC to provide scientific engineering
        and management support for energy and environmental programs.
        Many innovative technical and management ideas successfully used
        by CRC to support other clients have proven directly applicable
        to energy and environmental problems.  Technologies developed by
        CRC include an eye-safe Coherent Laser Radar 3-D mapper and
        precision measurement system; a robotically operated Facility
        Characterization System with both optical and chemical sensors;
        Data Fusion, whereby complex dissimilar data generating systems
        can be combined to provide 3-D subsurface imaging; and improved
        ground penetrating radar for greater exploration depths and
        sophisticated 3-D subsurface imaging.

             In support of the Office of Environmental Restoration and
        Waste Management at the Headquarters of the Department of Energy
        (DOE), CRC provides engineering and technical analysis,
        administrative and financial management support services, quality
        assurance and assessment support services, task force support and
        education, training and logistical support for outreach
        activities (the "EM-10 Project").

             In October 1994, CRC, as a member of the Lockheed team, won
        a five-year cost plus award fee contract with a present value of
        approximately $100,000,000 to support the management and
        operations of the Idaho National Engineering Laboratory near
        Idaho Falls, Idaho (the "INEL Project").  Under this contract,
        CRC will provide centralized training to augment and develop
        technical training programs for the conduct of operations,
        compliance training, criticality training, environmental safety
        and health training, and other training skills.  In addition, CRC
        will provide data base design architecture definition and other
        related data base support.

             To continue its diversification, in early 1993, CRC
        initiated a Health Systems Engineering Operation to bring its
        successful systems engineering methodology and technology
        developments to the health systems area.  CRC  recently won a
        contract with the State of South Carolina to provide facilities
        management to the Center for Computing and Information Technology
                                       65

        at the Medical University of South Carolina.  CRC will provide
        services in the areas of health care systems, academic and
        research computing, University financial systems, University
        business systems, infrastructure systems, customer service teams,
        enterprises support services, and financial analysis systems.  As
        part of this effort, CRC will evaluate technologies developed for
        federal government applications for their applicability to health
        care and medical information systems.  CRC is also supporting the
        Medical University of South Carolina in a number of  other high
        technology initiatives and is conducting investigative and
        therapeutic clinical trials for pharmaceutical manufacturers.


           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                        AND RESULTS OF OPERATIONS OF CRC

        General

             CRC was formed in October 1980 to provide systems
        integration, systems engineering, and analytical services to both
        government and industry.

             CRC's revenues are derived primarily from contract services
        provided by it to the U.S. Department of Defense and the U.S.
        Department of Energy.  These services are generally provided
        either under cost-reimbursement contracts, which provide for the
        reimbursement of direct costs and allowable indirect costs, plus
        a fee or profit component, or under firm fixed-price contracts,
        which provide a fixed price for stipulated systems or services to
        be provided by CRC.  Cost-reimbursement contracts are typically
        billable monthly or bi-monthly while fixed-price contracts
        generally provide for progress payments based on the attainment
        of specified milestones.

             CRC's recent growth can be primarily attributed to its
        success in attracting larger contracts than in the past and to
        certain acquisitions made by CRC in its efforts to diversify the
        areas in which it provides services.  

             In October of 1992, the TMD Targets Program was awarded to
        CRC as a four-year cost plus fixed fee procurement with the U.S.
        Army Space and Strategic Defense Command in Huntsville, Alabama
        with a present value of approximately $197,000,000, including all
        options.  In January 1993, the EM-10 Program was awarded to CRC
        as a five-year cost plus fixed fee level of effort procurement
        with the Department of Energy Headquarters in Washington D.C.
        with a present value of approximately $53,000,000, including all
        options.  In December 1992, the THAAD SETA Program was awarded to
        CRC as a five-year cost plus award fee task assignment program
        with the U.S. Army Space and Strategic Defense Command in
        Huntsville, Alabama with a present value of approximately
        $57,000,000, including all options.

             CRC's acquisitions include the acquisition in 1990 of two
        businesses providing military sciences and software and controls,
        in 1992 and 1993 of two businesses providing environmental
        services and in 1992 of a business providing intelligence and
        information technology services.

        Revenues

             Contract revenues for the 9-month period ended September 30,
        1994 increased 47% to $107,361,000 from $72,816,000 for the same
        period in the prior year.  The increase for the 9-month period
        resulted primarily from the maturing of the EM-10, TMD Targets
        and THAAD SETA Programs awarded to CRC during late 1992 and early
        1993.  

             Contract revenues increased to $104,790,000 in 1993 from
        $50,256,000 in 1992, a 109% increase.  Contract revenues
        increased to $50,256,000 in 1992, a 36% increase over 1991
        contract revenues of $37,054,000.  The increase in contract
        revenues for 1993 from 1992 was primarily due to initial revenues
        from new contracts awarded to CRC from October of 1992 through
        January of 1993.  The increase in contract revenues in 1992 from
        1991 was primarily due to the continued growth of ongoing
        business, the acquisition of an intelligence and information
        technology services business in 1992 and CRC's initial entry into
        the Department of Energy Headquarters support and the awards of
        the TMD Targets Program in October 1992.

        Costs and Expenses

             Cost of contract revenues as a percentage of contract
        revenues during the 9-month period ended September 30, 1994
        decreased to 90.8 % from 93.0 % for the same period in the prior
        year.  This decrease was the result of higher than normal
        start-up expenses incurred during the 1993 period in connection
        with new contracts.  

             The cost of contract revenues as a percentage of contract
        revenues increased to 94.2% in 1993 from 90.6% in 1992 and from
        86.3% in 1991.  These increases were the result of CRC's trend
        towards larger contract awards than in the past with smaller
        profit margins being available in the larger contracts, as
        compared to smaller contracts, due to competitive conditions.  

             Selling, general and administrative expenses as a percentage
        of contract revenues during the 9-month period ended September
        30, 1994 increased to 5.7% from 5.6% for the same period in the
        prior year, primarily due to increased personnel costs incurred
        to enable CRC to bid on larger contracts in the first nine months
        of 1994.  

             Selling, general and administrative expenses as a percentage
        of contract revenues decreased to 5.0% in 1993 from 7.9% in 1992
        and from 7.3% in 1991.  The decrease from 1992 to 1993 was
                                       67

<PAGE>





        primarily due to the fact that CRC increased its total contract
        base during 1993 without incurring comparable increases in
        selling, general and administrative expenses.  The increase from
        1991 to 1992 was primarily due to heavy proposal activity which
        occurred during 1992.  

        Interest

             Interest expense during the 9-month period ended September
        30, 1994 increased to $207,000 from $73,000 compared to the same
        period in the prior year, primarily due to increased borrowing by
        CRC under its bank line of credit, necessitated by cash flow
        requirements due to continued expansion and slower than normal
        payments by the government during the period.  This increase in
        interest expense was slightly offset as a result of the
        implementation in mid-1994 of electronic funds transfers under
        CRC government contracts, which improved CRC's cash receipts and
        lowered its borrowing requirements during the 1994 period.  

             Interest expense increased to $93,000 in 1993 from $26,000
        in 1992 as a result of increased borrowing incurred in 1993 under
        CRC's line of credit incurred to fund growth.  Interest expense
        decreased to $26,000 in 1992 from $65,000 in 1991 as a result of
        lower borrowing levels under CRC's line of credit.

        Provision for Income Taxes

             CRC is taxed as a professional service corporation at the
        highest prevailing corporate tax rate.  CRC's effective tax rate
        was 40% for the 9-month period ended September 30, 1994 and 44%
        for the nine-month period ended September 30, 1993, 32.4% for
        1993, 45.5% for 1992, and 38.3% for 1991.  The increases in CRC's
        tax rate from 1991 to 1993 were primarily due to changes in
        Internal Revenue Service regulations.


        Liquidity and Capital Resources

             CRC's primary sources of liquidity are provided by
        operations and a $10,500,000 revolving credit loan agreement.  At
        September 30, 1994, December 31, 1993, and December 31, 1992, the
        borrowings outstanding under such agreement were $3,233,000,
        $5,375,000, and $1,000,000, respectively.  Capital expenditures
        were $3,531,000 for the 9-month period ended September 30, 1994,
        $5,794,000 in 1993, and $3,360,000 in 1992.  Expenditures for
        rental of facilities and equipment were $3,538,000 for the
        9-month period ended September 30, 1994.

             Although accounts receivable increased to $26,456,000 at
        December 31, 1993, from $15,911,000 at December 31, 1992, this
        increase has not impaired CRC's cash flow.  CRC continues to
        actively monitor receivables with emphasis placed on collection
        activities and the negotiation of more favorable payment terms,
        and has seen an improvement in collections in 1994 as a result of
                                       68

<PAGE>





        the implementation in 1994 of electronic fund transfers under CRC
        government contracts.

             CRC's cash flows from operations plus its borrowing capacity
        are expected to provide sufficient funds for its operations and
        planned capital expenditures.

             allocated through December 1, 1994 to accounts maintained
             for the members of such group pursuant to CRC's KSOP.

        Ownership of Thermo Common Stock

             After giving effect to the Merger, assuming full
        participation in the Merger by all CRC shareholders and the prior
        exercise of all outstanding options to purchase CRC Common Stock,
        there will be approximately 53,526,635 shares of Thermo Common
        Stock outstanding.  After giving effect to the Merger, CRC
        shareholders would own in the aggregate approximately 4.99% of
        the issued and outstanding shares of Thermo Common Stock.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

             CRC leases an office building in Orlando, Florida (the "CRC
        Lakehurst Facility"), from Thomas J. Coleman.  The lease has a
        term of 18 years ending March 31, 2003, and provides for
        renegotiation of the rental rate every three years.  The lease
        was last renegotiated in 1991 and currently provides for monthly
        rental payments of approximately $31,500.  CRC will continue to
        lease space in the CRC Lakehurst Facility upon consummation of
        the Merger.

             CRC leases office and laboratory space in Orlando, Florida
        (the "Coleman Laboratories Facility"), from Coleman Family
        Properties, Ltd., and entity owned directly or indirectly by
        Thomas J. Coleman and members of his family.  The lease has a
        term of five years ending December 31, 1999, and requires the
        lessor to pay all real property taxes and insurance.  The monthly
        rental payment effective January 1, 1995 will be approximately
        $46,400.

             CRC leases office space in Huntsville, Alabama (the "CRC
        Huntsville Facility"), from Research Properties Partnership, a
        general partnership of which James B. Morrison, Thomas J.
        Coleman, Michael A. Coleman, Cynthia C. Patz and Robert V. Wells
        and partners.  The lease has a term of 18 years ending on April
        1, 2008, and provides for monthly rental payments equal to the
        greater of the partnership's mortgage payments or the amount
        allowed by the Defense Contract Audit Agency. 


                     CERTAIN FEDERAL INCOME TAX CONSEQUENCES

             The following is a summary of the principal federal income
        tax consequences of the Merger and is based upon the applicable
        provisions of the Code, regulations thereunder, and published
        rulings and court decisions.  Neither CRC nor Thermo intend to
        seek a ruling from the Internal Revenue Service with regard to
        the tax consequences of the Merger.

             CRC and Thermo have received an opinion from Sirote &
        Permutt, P.C., counsel for CRC, that under present law, and based
        upon the representations contained in the representation letter
        provided to such counsel by CRC, the Merger and the conversion of
        each share of CRC Common Stock into Thermo Common Stock should
        have the following consequences for federal income tax purposes:

                  1.   The Merger will qualify as a "reorganization" as
             defined in Code Sections 368(a)(1)(A) and 368(a)(2)(E).


                                       74

<PAGE>





                  2.   No gain or loss will be recognized by CRC as a
             result of the Merger.

                  3.   No gain or loss will be recognized by CRC
             shareholders who exchange all of their CRC Common Stock
             solely for Thermo Common Stock in the Merger.  Shareholders
             who exercise dissenters' rights will recognize gain or loss
             upon the receipt of cash for their shares measured by the
             difference between the cash received and the basis of their
             stock, provided they own no shares of Thermo Common Stock.

                  4.   The aggregate basis of the Thermo Common Stock
             received by a CRC shareholder will be the same as the
             aggregate basis of such shareholder in the CRC Common Stock
             converted in the Merger.

                  5.   The holding period of the Thermo Common Stock
             received by a CRC shareholder will include the period during
             which such shareholder held the CRC Common Stock converted
             in the Merger, provided that such stock was held as a
             capital asset on the Effective Date.

                  6.   A CRC shareholder who receives a cash payment in
             lieu of a fractional share of Thermo Common Stock will be
             treated as if such fractional share were distributed in the
             Merger and then redeemed by Thermo, and should recognize
             capital gain or loss measured by the difference between the
             amount of cash received and the shareholder's basis in the
             fractional share (which will be a pro rata portion of the
             shareholder's basis in the Thermo Common Stock received in
             the Merger), provided that such shareholder's CRC Common
             Stock is held as a capital asset on the Effective Date.

                  7.   No gain or loss for federal income tax purposes
             will be recognized by the holder of an option to purchase
             shares of CRC Common Stock solely as a result of the
             conversion of such options into options to purchase Thermo
             Common Stock.

             In order for the Merger to qualify as a tax-free
        reorganization, the CRC shareholders must have the requisite
        "continuity of interest" through ownership of the Thermo Common
        Stock.  It is the ruling position of the Internal Revenue Service
        that the "continuity of interest" requirement is satisfied if
        there is a continuing interest through stock ownership in the
        acquiring corporation on the part of the former shareholders of
        the acquired corporation, without any plan or intention by the
        former shareholders of the acquired corporation to sell, exchange
        or otherwise dispose of stock of the acquiring corporation, that
        is equal in value, as of the effective date of the
        reorganization, to at least 50% of the value of all the formerly
        outstanding stock of the acquired corporation as of the same
        date.  Sirote & Permutt, P.C., has concluded as part of their
        opinion, based upon the representations referred to above, that
                                       75
PAGE
<PAGE>





        the "continuity of interest" requirement will be satisfied in
        connection with the Merger.  There can be no assurance, however,
        that the former shareholders of CRC will not, pursuant to a
        present plan or intention, sell or otherwise dispose of the
        Thermo Common Stock in a sufficient amount to violate this
        requirement.  However, the holders of a majority of such shares
        have represented that they have no such present plan or
        intention.

             Holders of CRC Common Stock are urged to consult with their
        tax advisers as to the effect under state, local and foreign
        income and other tax laws of the Merger.

        or has the right to acquire through the exercise of stock options
        shares of Thermo Common Stock and shares of the common stock of
        certain of Thermo's subsidiaries the fair market value of which
        exceeds $50,000.  In addition, Sirote & Permutt, P.C., has

                               -- PROPOSAL TWO --

           APPROVAL OF AMENDED AND RESTATED ARTICLES OF INCORPORATION

             CRC's current Articles of Incorporation, as amended,
        restrict ownership of the outstanding securities of CRC to
        employees of CRC.  In order to facilitate the Merger, CRC's Board
                                       76
PAGE
<PAGE>





        of Directors proposes to adopt the Amended Articles, which delete
        the provisions restricting ownership of the securities of CRC to
        employees and which restate the Article of Incorporation by
        incorporating all previous amendments still in effect.  The
        Amended Articles are attached to this Proxy Statement/Prospectus
        as APPENDIX II.

             THE MANAGEMENT AND BOARD OF DIRECTORS OF CRC RECOMMEND THAT
        CRC SHAREHOLDERS VOTE IN FAVOR OF THE AMENDED ARTICLES.


                              -- PROPOSAL THREE --

                APPROVAL OF THE COLEMAN LABORATORIES TRANSACTION

             On January 6, 1992, CRC entered into an agreement (the
        "Katoot Agreement") with Mohammad Walid Katoot and MK Industries,
        Inc. ("MKI"), a corporation controlled by Mr. Katoot.  The Katoot
        Agreement involved the development and exploitation of an
        approach to synthesizing a new class of materials having certain
        unique properties.

             On November 29, 1993, CRC became the sole limited partner of
        Coleman Laboratories, Ltd., a limited partnership ("Coleman
        L.P."), by acquiring a 49% interest in Coleman L.P.  The general
        partner of Coleman L.P. is Coleman Laboratories, Inc., a
        corporation owned and controlled by Thomas J. Coleman and members
        of Mr. Coleman's immediate family.  On May 26, 1994, CRC and
        Coleman L.P. entered into a licensing agreement that gave CRC
        exclusive exploitation rights to material when and if developed
        by Dr. Katoot or MKI (the "1994 License Agreement").

             To satisfy a condition to the consummation of the Merger,
        CRC proposes (i) to transfer its 49% interest in Coleman L.P. to
        entities related to Thomas J. Coleman or his children and (ii) to
        terminate its relationship with Dr. Katoot and MKI by assigning
        and selling to Coleman L.P. for $10.00 (a) its rights under the
        Katoot Agreement; (b) the 1994 License Agreement; (c) the
        business of CRC related to the Katoot Agreement; and (d) certain
        equipment currently used by MKI (collectively, the "Coleman
        Laboratories Transaction").  CRC has received no revenue from its
        interest in the Katoot Agreement, the 1994 Licensing Agreement or
        Coleman L.P. and does not expect to receive revenues in the
        immediate future from these interests if the Coleman Laboratories
        Transaction does not occur.  Coleman L.P. will indemnify and hold
        CRC harmless from its obligations under the Katoot Agreement.  If
        approved by the CRC Shareholders, the Coleman Laboratories
        Transaction will occur immediately prior to the Merger.

             The Form of Assignment Agreement with respect to the Coleman
        Laboratories Transaction, together with all relevant exhibits,
        are attached to this Proxy Statement/Prospectus as APPENDIX III.


                                       77
PAGE
<PAGE>





             Under Florida law, approval of the Coleman Laboratories
        Transaction requires the affirmative vote of the holders of a
        majority of the shares entitled to vote at the Special Meeting,
        excluding the share beneficially owned by Thomas J. Coleman and
        members of his family.  THE CRC MANAGEMENT AND BOARD OF DIRECTORS
        RECOMMEND THAT CRC SHAREHOLDERS VOTE IN FAVOR OF THE COLEMAN
        LABORATORIES TRANSACTION.


                                  OTHER MATTERS

             CRC is not aware of any other matters to be presented at the
        Special Meeting of Shareholders other than as specified in the
        notice of such meeting and this Proxy Statement/Prospectus.


                            PROPOSALS OF STOCKHOLDERS

             The deadline for the submission of proposals of stockholders
        of Thermo for inclusion in the proxy statement and form of proxy
        relating to the 1995 annual meeting of stockholders was December
        15, 1994.  Accordingly, under applicable Commission regulations,
        shareholders of CRC who become stockholders of Thermo solely as a
        result of the Merger will not be able to submit proposals for
        inclusion in the proxy statement and form of proxy relating to
        that meeting.

Board of Directors
Coleman Research Corporation and Subsidiary
Orlando, Florida

                          INDEPENDENT AUDITORS' REPORT

       We have audited the accompanying consolidated balance sheets of Coleman
Research Corporation and Subsidiary as of December 31, 1993 and 1992, and the
related consolidated statement of earnings, stockholders' equity, and
consolidated cash flows for the year ended December 31, 1993. These financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

       We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

       In our opinion, the consolidated financial statements referred to above
presents fairly, in all material respects, the consolidated financial position
of Coleman Research Corporation and Subsidiary as of December 31, 1993 and 1992,
and the results of its operations and its cash flows for the year ended December
31, 1993, in conformity with generally accepted accounting principles. 

       Because we were not engaged to audit the consolidated statements of
earnings, changes in stockholders' equity and cash flows for the year ended
December 31, 1992, we did not extend our auditing procedures to enable us to
express an opinion on the consolidated results of operations and cash flows.
Accordingly, we do not express an opinion on them.

       The 1991 consolidated financial statements were reviewed by us and our
report thereon dated April 1, 1992, stated we were not aware of any material
modifications that should be made to those statements for them to be in
conformity with generally accepted accounting principles. However, a review is
substantially less in scope than an audit and does not provide a basis for the
expression of an opinion on the financial statements taken as a whole.

       As discussed in Note N, the 1993 and 1992 financial statements have been
restated and reissued to reflect subsequent events.

                   COLEMAN RESEARCH CORPORATION AND SUBSIDIARY
                          NOTES TO FINANCIAL STATEMENTS




NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

GENERAL:  The Company is a contractor providing systems integration, software,
prototype development, analytical services and scientific and engineering
technical assistance for the United States Government and private industries.
Work is performed generally under fixed price and cost plus fixed fee contracts.

CONSOLIDATION:  The consolidated financial statements include the accounts of
Coleman Research Corporation and its wholly-owned subsidiary, Coleman
Technologies, Inc. All significant intercompany transactions and accounts have
been eliminated in consolidation.

ACCOUNTING CHANGES:  The Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting for
Income Taxes", which requires a change from the deferred method to the asset and
liability method of accounting for income taxes. Under the asset and liability
method, deferred income taxes are recognized for the tax consequences of
"temporary differences" by applying enacted statutory tax rates applicable to
future years to differences between the financial statement carrying amounts and
the tax bases of existing assets and liabilities. Under SFAS No. 109, the effect
on deferred taxes of a change in tax rates is recognized in income in the period
that includes the enactment date. Under the deferred method, deferred taxes were
recognized using the tax rate applicable to the year of the calculation and were
not adjusted for subsequent changes in tax rates. The company elected to adopt
SFAS No. 109 in 1993 and has reported the cumulative effect of the change in the
method of accounting for income taxes as of the beginning of the 1993 fiscal
year in the consolidated statement of earnings.

Effective January 1, 1992, the Company adopted the straight line method of
depreciating its property and equipment acquired in 1992 and thereafter. The
purpose of this change is to better allocate the cost of these assets against
the revenues they produce. This change is being accounted for prospectively. If
the Company continued using the declining balance method of depreciating
property and equipment, depreciation expense would have increased by $158,406 in
1992.

REVENUE RECOGNITION:  Revenues under cost-reimbursement contracts are recorded
as costs are incurred and include estimated earned fees in the proportion that
costs incurred to date bear to total estimated costs. The estimated sales value
of performance under fixed price contracts in process is recognized under the
percentage of completion method of accounting whereunder the estimated sales
value is determined on the basis of physical completion to date (the total
contract amount multiplied by percent of performance to date less sales value
recognized in the previous periods). Costs, including general and administrative
expenses, are expensed as incurred. In the event of cost overruns on contracts,
the estimated loss on the contract is recognized in full at the time the loss
can be reasonably determined.

Contract costs include all direct labor, materials and subcontract costs and all
overhead costs related to contract performance, such as indirect labor, rent,
insurance, supplies, utilities, travel, depreciation and amortization. General
and administrative expenses consists of expenses not related to contract
performance.

                          NOTES TO FINANCIAL STATEMENTS




NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

Costs under U.S. Government contracts are subject to audit by the appropriate
U.S. Government agency. Management believes that cost disallowances, if any,
arising from audits of costs charged to government contracts through December
31, 1993 would not have a material effect on the financial position of the
Company.

EARNINGS PER SHARE:  Primary and fully diluted earnings per share have been
computed based on the weighted average number of common shares outstanding
during the year, which includes all common stock equivalents.

STOCK SPLITS:  All share and per share information has been restated to reflect
a ten-for-one stock split occurring November 10, 1992.

PROPERTY AND EQUIPMENT:  Property and equipment are stated at cost. Depreciation
is computed using the straight-line and declining balance methods for financial
and income tax reporting purposes over the estimated useful lives of the assets
as follows:
      Furniture and fixtures                          5-7 years
      Equipment, computers and software               2-5 years
      Computer equipment on operating lease             5 years
      Leasehold improvements                         5-40 years

Expenditures for additions, major renewals and betterments are capitalized and
expenditures for maintenance and repair are charged to income as incurred. Upon
sale or retirement of items of equipment, the cost and related accumulated
depreciation are eliminated from the accounts and the resulting gain or loss, if

As lessor, the Company has entered into an agreement to lease computer equipment
costing $313,385 which is accounted for under the operating method, which
recognizes income ratably over the life of the lease (See Notes C and D).

company. The carryover cost basis of the stock is $10,000. The shares are not
traded publicly, but have a book value of $26,361 at December 31, 1993.

NOTE B - ACCOUNTS RECEIVABLE:

The following schedule provides a breakdown of accounts receivable from
long-term contracts and programs, in which the Company acts as either the prime
contractor or a subcontractor:

                                               1993            1992

                                            ===========     ===========

Recoverable costs and accrued profit not billed comprise principally amounts of
reimbursable costs and revenues recognized on contracts for which billings had
not been presented to the contract owners because the amounts were not billable
at the balance sheet date. As of September 30, 1994, $5,054,721 of the unbilled
amounts receivable from customers at December 31, 1993 had been billed. The
remaining unbilled balances consisted principally of contract cost and fee
retentions, the final payment of which is contingent upon an audit of contract
costs by the Defense Contract Audit Agency. The Company is unable to reasonably
estimate the collection date of these receivables, which may extend beyond one
year. Therefore, in accordance with industry practice, the Company classifies as
current all contract related assets and liabilities, which includes billed and
unbilled accounts receivable.

NOTE C - LEASES:

The Company is party to several lease agreements for equipment that are
accounted for as capital leases. Amortization on equipment under capital lease
agreements amounted to $14,996 in 1993, $2,813 in 1992 and $14,586 in 1991.

Effective January 1, 1993, the company changed it method of accounting for

Number 109 - Accounting For Income Taxes, as issued by the Financial Accounting
Standards Board.

This new accounting standard requires that income tax expense be computed based
on the actual expense incurred for the period plus deferred taxes resulting from
temporary differences in income for financial and tax purposes, using the
liability method. The temporary differences result primarily from using the cash
basis method of accounting and accelerated depreciation methods for income tax
reporting. In adopting this new method, the company elected not to restate prior
year earnings and to include the cumulative effect of this accounting change in
1993 earnings.

the FDIC insured amount by $141,961. The Company grants credit and provides
services to the Department of Defense, Department of Energy and private
industries on a national basis. The U.S. Government retains the right to
terminate a contract or reduce funding, subject to terms agreed to in the
contracts. Additionally, costs billed under U.S. Government contracts are
subject to final audit and negotiation by the appropriate contracting agency
prior to final payment.

NOTE N - REVISION OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS:

The 1993 financial information provided in these financial statements have been
revised to reflect changes resulting from the revision of estimated contract
cost data, overhead rates and subsequent renegotiation of fees to be earned on
certain contracts, which resulted in a reduction of sales of $1,840,855. These
revisions were based upon new information obtained subsequent to the issuance of
the originally issued financial statements on May 31, 1994.

The 1992 financial statements have been reissued reflecting changes made based
on revised contract cost estimates, settlement of a state sales and use tax
audit arising in 1994 for transactions occurring in 1992 and prior, and
increased estimates of accrued vacation pay and other items.

                          AGREEMENT AND PLAN OF MERGER


             THIS AGREEMENT, dated as of the _____ day of January, 1995,
        by and among Thermo Electron Corporation, a Delaware corporation
        having an office at 81 Wyman Street, Waltham, Massachusetts
        02254-9046 ("Thermo"), CRC Acquisition Corp., a Delaware
        corporation and a wholly-owned subsidiary of Thermo
        ("Acquisition") and Coleman Research Corporation, a Florida
        corporation having an office at 201 South Orange Avenue, Suite
        1300, Orlando, Florida 32801 ("CRC" or the "Company").

             WHEREAS, the Boards of Directors of Acquisition and CRC deem
        it advisable and in the best interest of such corporations and
        their respective shareholders that Acquisition be merged into and
        with CRC on the terms and conditions set forth in this Agreement,
        as a result of which CRC will become a wholly-owned subsidiary of
        Thermo; and

             WHEREAS, the Board of Directors of Thermo has approved the
        merger;

             NOW THEREFORE, for and in consideration of the mutual
        covenants and agreements hereinafter set forth, and other good
        and valuable consideration, the receipt of which is acknowledged
        by each party hereto, the parties hereto agree as follows:


                                    ARTICLE 1

                                   THE MERGER

             Section 1.1.  Agreement and Plan of Merger.  Effective as of
        the Effective Date (as defined in Section 2.2 below), Acquisition
        shall be merged with and into CRC (hereinafter sometimes called
        the "Merger") in accordance with the terms of this Agreement and
        the Articles of Merger set forth in Exhibit A hereto (the
        "Articles of Merger").  CRC shall be the corporation surviving
        the Merger (the "Surviving Corporation"), and the separate
        existence of Acquisition shall cease as of the Merger.  The
        Amended and Restated Articles of Incorporation and Bylaws of CRC,
        in effect immediately prior to the effective time of the Merger,
        shall thereafter continue in full force and effect as the
        Articles of Incorporation and Bylaws of the Surviving
        Corporation.  The directors and officers of the Surviving
        Corporation, from and after the Effective Date, shall be the
        directors and officers listed in the Articles of Merger, each to
        hold office in accordance with applicable law and the Amended and
        Restated Articles of Incorporation and Bylaws of CRC.  The effect
        of the Merger shall be as provided by the applicable provision of
PAGE
<PAGE>





        the General Corporation Law of the State of Delaware, the Florida
        General Corporation Act and the Florida Business Corporation Act.

             Section 1.2.  Conversion of  CRC's Shares.  At the effective
        time of the Merger, each share of CRC's common stock outstanding
        immediately prior thereto (herein referred to as a "CRC Share"
        and collectively as the "CRC Shares") shall, by virtue of the
        Merger and without any action on the part of the holder thereof,
        but subject to this Section and to Sections 1.4, 1.5, 1.6 and 1.7
        below, be canceled and converted into the right to receive  
        .1905695 shares (the "Thermo Shares") of Thermo common stock,
        $1.00 par value (the "Thermo Common Stock").  The fraction of a
        Thermo Share into which each CRC Share is to be converted
        pursuant to this Agreement is hereinafter referred to as the
        "Exchange Ratio."  

             Section 1.3.  CRC Stock Options.  At or prior to the
        Effective Date, Thermo and CRC shall take all action necessary to
        cause the assumption by Thermo as of the Effective Date of the
        options to purchase CRC common stock outstanding as of the
        Effective Date (the "CRC Options").  Each of the CRC Options
        shall be converted without any action on the part of the holder
        thereof into an option to purchase shares of Thermo Common Stock
        (the "Thermo Options") as of the Effective Date.  The number of
        shares of Thermo Common Stock that each record holder of an
        option agreement which represents CRC Options (the
        "Optionholders") shall be entitled to receive upon the exercise
        of such option shall be a number of whole and fractional shares
        determined by multiplying the number of shares of CRC common
        stock subject to such option, determined immediately before the
        Effective Date, by the Exchange Ratio.  The option exercise price
        of each share of Thermo common stock subject to an assumed CRC
        Option shall be the amount (rounded up to the nearest whole cent)
        obtained by dividing the exercise price per share of CRC common
        stock at which such option is exercisable immediately before the
        Effective Date by the Exchange Ratio.  The assumption and
        conversion of CRC Options to Thermo Options as provided herein
        shall not give the Optionholders additional benefits which they
        did not have immediately prior to the Effective Date, result in
        any acceleration of any vesting schedule for any CRC Option,
        other than the acceleration of the vesting schedules pursuant to
        the terms of the CRC Nonqualified Stock Option Plan dated January
        2, 1990 (the "Option Plan"), or relieve the Optionholders of any
        obligations or restrictions applicable to their options or the
        shares obtainable upon exercise of the options.  Only whole
        shares of Thermo Common Stock shall be issued upon exercise of
        any Thermo Option and in lieu of receiving any fractional share
        of Thermo Common Stock, the holder of such option shall receive
        in cash the fair market value of the fractional share, net of the
        applicable exercise price of the fractional share and applicable
        withholding taxes.

             Section 1.4.  Limit on Issuance of Thermo Shares.  Anything
        to the contrary herein notwithstanding, the total number of
PAGE
<PAGE>





        Thermo Shares which shall be required to be issued pursuant to
        Section 1.2 and upon the exercise of CRC Options that are
        converted into Thermo Options pursuant to Section 1.3 shall not
        (except as such number of shares shall be required to be
        adjustment pursuant to Section 1.10) exceed 2,669,158.  In the
        event that the application of the Exchange Ratio set forth in
        Section 1.2 could result in the issuance of more than 2,669,158
        Thermo Shares, such Exchange Ratio rate shall be automatically
        adjusted such that the total number of Thermo Shares will not
        exceed 2,669,158.  

             Section 1.5.  Dissenting Shares.  Each outstanding CRC Share
        held by a CRC shareholder who has demanded and perfected his or
        her right to an appraisal of his or her CRC Shares in accordance
        with Sections 607.1301, 607.1302 and 607.1320 of the Florida
        Business Corporation Act and who has not effectively withdrawn or
        lost his or her right to such appraisal ("Dissenting Shares")
        shall not be converted into or represent the right to receive the
        Thermo Shares represented by such CRC Shares pursuant to Section
        1.2 above, but the holder thereof shall be entitled only to such
        rights as are granted by Sections 607.1301, 607.1302 and 607.1320
        of the Florida Business Corporation Act.

             Section 1.6.  Payment for the CRC Shares.  Promptly
        following the Effective Date of the Merger, The First National
        Bank of Boston, Thermo's stock transfer agent (the "Exchange  
        Agent"), shall transmit to each record holder of an outstanding
        certificate which prior thereto represented CRC Shares (the
        "Shareholders") a form of letter of transmittal and instructions
        for use in effecting the surrender of such certificate and/or
        option agreement in exchange for the Thermo Shares represented by
        such CRC Shares.  Upon the proper surrender of such certificates
        and a duly executed letter of transmittal and any required tax
        certifications, in accordance with such instructions, to the
        Exchange Agent, the Exchange Agent shall deliver a certificate
        for the Thermo Shares that such person is entitled to receive,
        minus the deduction specified in Section 1.7.  It shall be a
        condition of such payment and delivery that the surrendered
        certificate be properly endorsed or otherwise in proper form for
        transfer and that the person requesting such shall pay any
        transfer or other taxes required by reason of such payment or
        delivery or establish to the satisfaction of the Transfer Agent,
        Thermo and/or the Surviving Corporation that such tax has been
        paid or is not applicable.  Until so surrendered for exchange,
        each certificate heretofore representing CRC common stock (other
        than Dissenting Shares) shall, subject to Section 1.7 hereof, be
        deemed for all purposes to evidence the right to receive the
        consideration as described in accordance with Section 1.2 above;
        provided, however, that unless and until any such outstanding
        certificate is so surrendered, the holder of such outstanding
        certificate shall cease to have any rights as a stockholder of
        CRC, except such rights, if any, as such holder may have with
        respect to Dissenting Shares and shall not be entitled to receive
        any consideration from the Surviving Corporation and/or Thermo
PAGE
<PAGE>





        with respect to the CRC Shares represented by such certificate.
        Each Shareholder, upon surrender of each such certificate to the
        Exchange Agent, shall receive promptly in exchange for each such
        certificate the shares of Thermo Common Stock and cash (if any)
        to which such holder is entitled pursuant to Sections 1.2, 1.9
        and 1.10 of this Agreement.  Unless and until any such
        outstanding certificates for CRC Shares shall be so surrendered,
        no dividend (cash or stock) payable to holders of record of
        shares of Thermo Common Stock as of any date subsequent to the
        Effective Date shall be paid to the holder of any such
        outstanding certificate and his other rights as a stockholder of
        Thermo shall be suspended, but upon such surrender of such
        outstanding certificate there shall be paid to the record holder
        of the certificate of shares of Thermo Common Stock issued in
        exchange therefor the amount of dividends, if any, without
        interest and less any taxes which may have been imposed thereon,
        that have theretofore become payable with respect to the number
        of those shares of Thermo Common Stock represented by such
        certificate issued upon such surrender and exchange, and his
        other rights as a stockholder of Thermo shall thereafter be
        restored.

             Section 1.7.  Escrow Account.  For the purpose of providing
        support of the representations and warranties contained herein
        and to induce Thermo to enter into this Agreement, ten percent
        (10%) of Thermo Shares each Shareholder has the right to
        beneficially receive pursuant to Section 1.2 (including Thermo
        Shares to be issued to the CRC 401(k) Employee Stock Ownership
        Plan (the "KSOP")) shall be withheld from payment to such
        Shareholder pursuant to Section 1.2 and shall be set aside in
        escrow pursuant to the terms of an Indemnification and Stock
        Escrow Agreement to be entered into at the Closing by and among
        Thermo, CRC, the Shareholder Representative (as defined therein)
        and The First National Bank of Boston, as escrow agent, in
        substantially the form of Exhibit B hereto (the "Escrow
        Agreement").  The amount of shares placed in escrow pursuant to
        this Section 1.7 shall be considered the "Escrowed Shares."  The
        Escrowed Shares shall be held as a trust fund and shall not be
        subject to any lien, attachment, trustee process or any other
        judicial process of any creditor of any party, and shall be held
        and disbursed by the Escrow Agent solely for the purposes and in
        accordance with the terms of the Escrow Agreement.  It is
        intended that the assets held in escrow as above provided shall
        facilitate Thermo's and the Surviving Corporation's ability to
        recover amounts to which they are entitled under this Agreement
        or the Escrow Agreement as a result of misrepresentations,
        breaches of warranties and breaches of covenants contained in
        this Agreement and to satisfy claims of Thermo and Acquisition
        arising as a result of this Agreement or the Escrow Agreement.
        Accordingly, and to the extent necessary to provide such
        protection to Thermo and the Surviving Corporation, property held
        in escrow thereunder shall be available to satisfy claims of
        Thermo and the Surviving Corporation under this Agreement or the
        Escrow Agreement to the extent provided in such agreements.  The
PAGE
<PAGE>





        adoption of this Agreement and the approval of the Merger by the
        Shareholders shall constitute approval of the Escrow Agreement,
        including without limitation, placement and escrow of the
        Escrowed Shares and the appointment of the Shareholder
        Representative.

             Section 1.8.  Certain Other Agreements.  Concurrently with
        the execution and delivery of this Agreement, CRC shall deliver
        to Thermo:  (i) an Affiliate Agreement in the form of Exhibit C
        attached hereto and a Continuity of Interest Certificate in the
        form attached as Exhibit D hereto duly executed and delivered by
        each affiliate of CRC and other parties (collectively, the
        "Affiliate Agreements"); (ii) the noncompetition agreement
        between Thomas J. Coleman and CRC in the form of Exhibit E
        attached hereto duly executed and delivered by Thomas J. Coleman;
        (iii) amended employment agreements between CRC and each of James
        B. Morrison, Richard H. Levine and John L. Gardner in the form of
        Exhibit F attached hereto; and (iv) amended compensation
        agreements between CRC and certain key employees of CRC to be
        identified by Thermo.

             Section 1.9.  No Fractional Shares of Thermo Common Stock.
        Notwithstanding any other provision of this Agreement, neither
        certificates nor scrip for fractional shares of Thermo Common
        Stock shall be issued to any holder of CRC common stock in the
        Merger and the holder thereof shall not be entitled to any voting
        or other rights of a holder of shares or a fractional share
        interest.  Each CRC Shareholder who otherwise would have been
        entitled to receive a fraction of a share of Thermo Common Stock
        shall receive in lieu thereof cash, without interest, in an
        amount determined by multiplying such Shareholder's fractional
        interest by the closing price of Thermo Common Stock as reported
        on the New York Stock Exchange on the Effective Date.  All
        amounts of cash in respect of fractional interests which have not
        been claimed at the end of three years from the Effective Date by
        surrender of certificates for shares of CRC common stock shall be
        repaid to the Surviving Corporation, subject to the provisions of
        applicable escheat or similar laws, for the account of the
        holders entitled thereto.

             Section 1.10.  Adjustments.  In the event Thermo shall
        declare, pay, make or effect between the date of this Agreement
        and the Effective Date of the Merger (a) any stock dividend or
        other distribution in respect of the Thermo Common Stock payable
        in shares of capital stock of Thermo, (b) any stock split or
        other subdivision of outstanding shares of Thermo Common Stock
        into a larger number of shares, (c) any combination of
        outstanding shares of Thermo Common Stock into a smaller number
        of shares, (d) any reclassification of Thermo Common Stock into
        other shares of capital stock or securities, or (e) any exchange
        of the outstanding shares of Thermo Common Stock, in connection
        with a merger or consolidation of Thermo or sale by Thermo of all
        or part of its assets, for a different number of class of shares
        of stock or securities of Thermo or for the share of the capital
PAGE
<PAGE>





        stock or other securities of any other corporation, appropriate
        adjustment shall be made in the ratio for the conversion of CRC
        Shares into Thermo Shares as may be required to put the
        Shareholders in the same position as if the record date, with
        respect to any such transaction or transactions which shall so
        occur, had been immediately after the Effective Date of the
        Merger, or otherwise to carry out the intents and purposes of
        this Agreement.

             Section 1.11.  Closing of Stock Transfer Books.  The stock
        transfer books of CRC shall be closed at the close of business on
        the business day immediately preceding the Effective Date.  In
        the event of a transfer of ownership of CRC common stock, the
        shares of Thermo Common Stock and cash (if any) to be issued in
        the Merger as provided herein may be delivered to a transferee,
        if the certificate representing such CRC common stock is
        presented to the Exchange Agent, accompanied by all documents
        required to evidence and effect such transfer and by payment of
        any applicable stock transfer taxes.

             Section 1.12.  Lost Certificates.  In the event any
        certificate representing a Shareholder's   CRC Shares shall have
        been lost, stolen or destroyed, upon the making of an affidavit
        of that fact by the person claiming such certificate or option
        instrument to be lost, stolen or destroyed, the Exchange Agent or
        the Surviving Corporation shall issue in exchange for such lost,
        stolen or destroyed certificate or option instrument the
        consideration payable in exchange therefor pursuant to this
        Article 1.  The Board of Directors of the Exchange Agent or the
        Surviving Corporation may, in its discretion and as a condition
        precedent to the issuance thereof, require the owner of such
        lost, stolen or destroyed certificate to give the Exchange Agent
        or the Surviving Corporation a bond in such sum as it may direct

        hereto as Exhibit G (specifically identifying the relevant
        subsection hereof):

             (a)  Organization and Qualification.  CRC is a corporation
        duly organized, validly existing and in good standing under the
        laws of the State of Florida and has all requisite corporate and
        other power and authority to own, operate and lease its
        properties and to carry on its business as it is now being
        conducted.  The Articles of Incorporation and Bylaws of CRC, as
        amended to date, are attached hereto as Exhibit H.  The Company
        is duly qualified as a foreign corporation to do business, and is
        in good standing, in each jurisdiction in which the character of
        the properties owned, operated or leased by it or the nature of
        its activities is such that such qualification is required by
        applicable law.  All such jurisdictions are listed on the
        Disclosure Schedule.

             (b)  Capitalization.  The authorized capital stock of CRC
        consists of 50,000,000 shares of common stock, $.001 par value

        constitute the total issued and outstanding share capital of CRC.
        The Disclosure Schedule sets forth a complete and accurate list
        of all Shareholders, indicating the number of CRC Shares held by
        such Shareholder and such Shareholder's state of residence.  All
        of such shares have been duly authorized and validly issued, are
        fully paid, nonassessable and free of preemptive rights.  The
        offer and sale of all securities of the Company complied with all
        federal, state and foreign securities laws.  As of January __,
        1995, there were outstanding options to purchase an aggregate of

        in the amounts listed on the Disclosure Schedule, which list
        shall also include the state of residence of each such
        Optionholder.  All other options to purchase common stock of CRC

        options to purchase shares of CRC Common Stock.  Since January

        are reserved for issuance (except for the CRC Options), and
        except for the Stock Redemption Agreements dated __________ and
        __________ (the "Redemption Agreements") and as required under

        rights, agreements or commitments, contingent or otherwise,
        obligating CRC to issue, sell or purchase shares of capital
        stock.  The books and records of the Company, including without
        limitation the books of account, minute books, stock certificate
        books and stock ledgers, are complete and correct and accurately
        reflect the conduct of the business and affairs of the Company.

             (c)  Subsidiaries.  CRC has no subsidiaries.  Except for its
        interest in Coleman Laboratories, Ltd., the Company is not a
        partner or joint venturer with any other person.  The Company is
        not subject to any obligation, contingent or otherwise, to
        provide funds to or make an investment (in the form of a loan,
        capital contribution or otherwise) in any entity.

             (d)  Authority.  Subject to shareholder approval, the
        Company has full right, power, capacity and authority to execute,
        deliver and perform this Agreement, to execute, deliver and file
        the Articles of Merger and to consummate the transactions
        contemplated thereby.  This Agreement has been duly and validly
        authorized by all necessary corporate action on the part of the
        Company, subject only, in respect of the consummation of the
        Merger, to approval by the shareholders of CRC holding a majority
        in voting interest of the outstanding CRC Shares.  The Board of

        Agreement, the filing of the Articles of Merger nor the
        consummation of the transactions contemplated hereby will (i)
        conflict with or result in a violation, breach, termination or
        acceleration of, or default under (or would result in a
        violation, breach, termination, acceleration or default with the
        giving of notice or passage of time, or both) any of the terms,
        conditions or provisions of the Articles of Incorporation or
        Bylaws of the Company, as amended, or of any note, bond,
        mortgage, indenture, license, agreement or other instrument or

        Thermo prior to the execution of this Agreement true and complete
        copies of:  (i) the unaudited consolidated balance sheet of CRC

PAGE
<PAGE>





        in accordance with generally accepted accounting principles
        applied on a consistent basis with previous years both as to
        classification of items and amounts (except as may be indicated
        therein or in the notes thereto) and comply as to form in all
        material respects to the interpretations and pronouncements of
        the Commission, and the Financial Statements fairly present the
        financial condition, results of operations and cash flows of the
        Company as at the dates and for the periods indicated.  Measured
        in accordance with the same revenue recognition policies applied
        by the Company during calendar year 1993, the Company had
        contract revenues of at least $33,800,000 for the period
        beginning October 1, 1994 through December 31, 1994.  

             (f)  No Undisclosed Liabilities; No Dealings with

        date of the Balance Sheet in the ordinary course of business
        which are not in the aggregate or individually material.  As used

        indebtedness, claim, loss, damage, deficiency (including deferred
        income tax), cost, expense, guaranty or responsibility, whether
        known or unknown, absolute, accrued, contingent or otherwise, and
        whether due or to become due.  The Company does not have any
        contractual arrangement with, or commitment to or from, any of
        its shareholders, officers, management, directors, employees or
        their family members (other than such as may have been entered
        into in the normal course of employment), including, without
        limiting the generality of the foregoing, any contractual
        arrangement or commitment whereby any of such persons are
        directly or indirectly a joint investor or coventurer with
        respect to, or owner, lessor, lessee, licensor or licensee of,
        any real or personal property, tangible or intangible, owned or
        used by, or a lender to or debtor of, the Company. 

             (g)  Tax Matters.  

                  (i)  For purposes of this Agreement, "Tax" means any
             federal, state, local or foreign income, gross receipts,
             license, payroll, employment, excise, severance, stamp,
             occupation, premium, windfall profits, environmental

             any kind whatsoever, including without limitation any
             interest, penalty, or addition thereto, whether disputed or
             not.

                  (ii)  For purposes of this Agreement, "Tax Return"
             means any return, declaration, report, claim for refund, or
             information return or statement relating to Taxes, including
PAGE
<PAGE>





             without limitation any schedule or attachment thereto, and
             any amendment thereof.

                  (iii)  Except as set forth on the Disclosure Schedule,
             CRC and its Subsidiaries have accurately prepared and duly
             and timely filed all Tax Returns that they were required to
             file.  Except as set forth on the Disclosure Schedule, to
             the knowledge of CRC and its Subsidiaries all such Tax
             Returns were correct and complete in all material respects.
             All taxes owed by CRC and its Subsidiaries as reflected on
             the Tax Returns have been paid when due, other than those
             being contested in good faith and where adequate reserves
             have been established therefor.  Except as set forth on the
             Disclosure Schedule, none of CRC and its Subsidiaries is
             currently the beneficiary of any extension of time within
             which to file any Tax Return.  No claim or inquiry with
             respect to any material amount of Taxes has ever been made
             by an authority in a jurisdiction where CRC or any of its
             Subsidiaries did not file Tax Returns that it is or may be
             subject to any Tax by that jurisdiction for any period
             ending on or before the Closing Date.  There are no liens or
             other security interests on any of the assets of the CRC and
             its Subsidiaries that arose in connection with any failure
             (or alleged failure) to pay any Tax.

                  (iv)  Neither CRC nor any of its Subsidiaries has ever
             filed a consolidated return with a company other than CRC
             and its Subsidiaries.

                  (v)  CRC has delivered to Thermo true and complete
             copies of the income, franchise, excise, sales, use,
             property and employment tax returns filed by the CRC and its
             Subsidiaries with any federal, state, local or foreign
             governmental authority since January 1, 1988, together with
             all examination reports and statements of deficiencies
             assessed, proposed in writing to be assessed against, or
             agreed to by the CRC or its Subsidiaries.

                  (vi)  Except for Taxes attributable to the change in
             CRC's accounting method upon consummation of the Merger
             (from the cash method to the accrual method), all Taxes of
             CRC and its Subsidiaries attributable to Tax periods or
             portions thereof ending on or prior to the Effective Date,
             including Taxes that may become payable by CRC and its
             Subsidiaries in future periods in respect of any
             transactions or sales occurring on or prior to the Effective
             Date, that have not yet been paid have, in the aggregate,
             been adequately reflected as a liability on the books of CRC
             and its Subsidiaries in accordance with generally accepted
             accounting principles consistently applied.

                  (vii)  Without limiting the generality of the
             foregoing, CRC and its Subsidiaries have withheld or
             collected and duly paid all Taxes required to have been
PAGE
<PAGE>





             withheld or collected and paid in connection with payments
             to foreign persons, sales and use Tax obligations with
             respect to any and all states, and amounts paid or owing to
             any employee, independent contractor, creditor, stockholder
             or other person.

                  (viii)  None of the Tax Returns of CRC and its
             Subsidiaries have been or are being currently audited or
             examined by any governmental authority, nor have any
             deficiencies for any Tax been asserted against the CRC or
             any of its Subsidiaries.  

                  (ix)  There are no outstanding agreements or waivers
             extending the statute of limitations applicable to any Tax
             Return of CRC or any of its Subsidiaries for any period.

                  (x)  None of CRC and its Subsidiaries has filed a
             consent under Code Section 341(f) concerning collapsible
             corporations.  None of CRC and its Subsidiaries has made any
             payments, is obligated to make any payments, or is a party
             to any agreement that could obligate it to make any payments
             that will be an "excess parachute payment" under Code
             Section 380G.  None of CRC and its Subsidiaries has been a
             United States real property holding corporation within the
             meaning of Code Section 897(c)(2) during the applicable
             period specified in Code Section 897(c)(1)(A)(ii).  None of
             CRC and its Subsidiaries has been a passive foreign
             investment company as defined in Code Sections 1291-1297.
             Each of CRC and its Subsidiaries has disclosed on its
             federal income Tax Returns all positions taken therein that
             could give rise to a substantial understatement of federal
             income Tax within the meaning of Code Section 6662.  None of
             CRC and its Subsidiaries is a party to any Tax allocation or
             sharing agreement.  None of CRC and its Subsidiaries has any
             liability for any Taxes of any person (other than any of CRC
             and its Subsidiaries) under Treas. Reg. Section 1.1502-6 (or
             any similar provision of federal, state, local, or foreign
             law), as a transferee or successor, by contract, or

             (h)  Properties; Environmental, Health and Safety Matters.
        The Company has good, full and marketable title to, or a valid
        and continuing leasehold interest in, all properties and assets,
        real and personal, reflected on the Balance Sheet or acquired by
        the Company since the date of the Balance Sheet (except personal
        property leases terminated, or personal property sold or
        otherwise disposed of, in the ordinary course of business since
        the date of the Balance Sheet), free and clear of all mortgages,
        liens, attachments, pledges, encumbrances or security interests
        of any nature whatsoever, except for liens for taxes not yet due
        and the rights of any lessor under any lease to which CRC is a
        party.  The Company has never owned any real estate other than
        the improvements constructed on the real property leased by the
        Company at 5950 Lakehurst Drive, Orlando, Florida (the

        "Property").  All leases pursuant to which the Company leases
        real or personal property are in good standing, and are valid and
        in full force and effect in accordance with their respective
        terms.  There are no defaults under any such leases attributable
        to the Company, and no event has occurred that (whether or not
        with notice, lapse of time or both) would constitute a default.
        To the best knowledge of the Company, all buildings,
        improvements, machinery, equipment, vehicles and items of
        tangible personal property used in connection with the operations
        of the Company are structurally sound, are in good operating
        condition and repair, are adequate for the uses to which they are
        being put and are not in need of maintenance or repairs except
        for ordinary, routine maintenance.

        reasonable detail with respect to the Property and to the best of
        the Company's knowledge with respect to all other real property

              The Company is not and has not been in violation of any
        law, regulation or ordinance (including without limitation,
        Environmental Laws and laws, regulations or ordinances relating

<PAGE>





        currently or previously leased by the Company ever been the
        subject of environmental clean-up or remediation.  Neither the
        Property nor, to the best of the Company's knowledge, any other
        real property currently or previously leased by the Company
        contains any Hazardous Material (as defined below), nor has any
        Hazardous Material been discharged or spilled thereon.  The
        Company has never owned or operated a petroleum or hazardous
        waste landfill or any petroleum or other hazardous waste
        treatment, storage or disposal facility.  There are no past or
        present events, conditions, circumstances, activities, practices,
        incidents, actions or plans of the Company which may interfere
        with or prevent continued compliance, or which may give rise to
        any common law or legal liability, or otherwise form the basis of
        any claim, action, suit, proceeding, hearing, or investigation,
        based on or related to the disposal, storage, handling,
        manufacture, processing, distribution, use, treatment, or
        transport, or the emission, discharge, release or threatened
        release into the environment, of any pollutant or waste.  There
        are no proceedings affecting the Property or, to the best of the
        Company's knowledge, any other real property currently or
        previously leased by the Company, or, to the best of the
        Company's knowledge, threatened which could have an adverse
        effect on the present or future use of any such property for the
        purposes for which it was acquired or the purpose for which it is
        used.  Neither the Property nor, to the best of the Company's
        knowledge, any other real property currently or previously leased
        by the Company at any time is or has been on any federal or state
        "Superfund" list or on EPA's Comprehensive Response, Compensation
        and Liability Information System ("CERCLIS") list or on any
        analogous state environmental agency list.  The Company has not
        received any notice from any governmental agency or other party
        seeking any information or alleging any liability with regard to
        the real property occupied or used by the Company now or at any
        time or with regard to any off-site environmental conditions.
        The real property occupied by the Company is not subject to a
        lien under any Environmental Laws.

             For purposes of this Agreement, "Hazardous Material" means
        any petroleum product or any flammable, explosive or radioactive
        material, or any hazardous or toxic waste, substance or material,
        including substances defined as "hazardous substances",
        "hazardous materials", "solid waste" or "toxic substances" under
        any applicable laws relating to hazardous or toxic materials and
        substances, air pollution (including noise and odors), water
        pollution, liquid and solid waste, pesticides, drinking water,
        community and employee health, environmental land use management,
        stormwater, sediment control, nuisances, radiation, wetlands,
        endangered species, environmental permitting and petroleum
        products, and may include, but not be limited to, the Federal
        Insecticide, Fungicide, and Rodenticide Act, as amended; the
        TSCA; the CWA; the National Environmental Policy Act, as amended;
        the Solid Waste Disposal Act, as amended; the CERCLA, as amended;
        the Clean Air Act, as amended; the Emergency Planning and
PAGE
<PAGE>





        Community Right-to-Know Act, as amended; the Occupational Safety
        and Health Act, as amended; Hazardous Materials Transportation
        Act, as amended; and all rules and regulations promulgated
        pursuant to such federal, state, and county and foreign laws and
        ordinances.

             (i)  Accounts Receivable.  All accounts and notes receivable
        of the Company shown on the Balance Sheet and all accounts and
        notes receivable acquired by the Company subsequent to the date
        of the Balance Sheet to the date hereof are valid and
        enforceable, to the best knowledge of the Company are not subject
        to any defense, set-off, counterclaim or claim for refund, have
        arisen in the ordinary course of business and have been
        collected, or are in the process of collection and are
        collectible in the ordinary course of business and (with the
        exception of receivables to be collected in connection with
        contract close-outs in an aggregate amount not to exceed
        $100,000) in any event within six months from the Effective Date,
        in the aggregate recorded amounts thereof, less the applicable
        allowances reflected on the Balance Sheet with respect to the
        accounts and notes receivable shown thereon, or set up consistent
        with past practice on the books of the Company with respect to
        the accounts and notes receivable acquired subsequent to the date
        of the Balance Sheet.

             (j)  Purchase and Sale Commitments.  No outstanding purchase
        commitments by the Company are in excess of the normal, ordinary
        and usual requirements of the business of the Company, and the
        aggregate of the contract prices to which the Company has agreed
        in any outstanding purchase commitments is not so excessive when
        compared with current market prices for the relevant commodities
        or services that a material loss is likely to result.  No
        outstanding commitment by the Company obligates the Company to
        sell any product or service at a price which, because of
        currently prevailing and projected costs of materials or labor,
        is likely to result, when all such sales commitments are taken in
        the aggregate, in a loss to the Company.  Except as set forth on
        the Disclosure Schedule and except for the U.S. Government, there
        are no suppliers to the Company of significant goods or services
        with respect to which practical alternative sources of supply, or
        comparable products, are not available on comparable terms and
        conditions.

             (k)  Governmental Authorizations.  Set forth on the
        Disclosure Schedule is a complete and accurate list of all
        material governmental permits, licenses, franchises, concessions,
        zoning variances and other approvals, authorizations and orders
        which have been obtained in connection with the conduct of the
        business now being conducted by the Company.  Such permits,
        licenses, franchises, concessions, zoning variances, approvals,
        authorizations and orders constitute all governmental permits,
        licenses, franchises, concessions, zoning variances, approvals,
        authorizations and orders which are required under all applicable
        local, state, federal or foreign laws and regulations for the
PAGE

        operation of the business being conducted by the Company as it
        has been heretofore conducted.  All such permits, licenses,
        franchises, concessions, zoning variances, approvals,
        authorizations and orders are presently in full force and effect,
        the Company is in compliance with the requirements thereof
        (except for minor violations that could not result in a
        suspension or forfeiture thereof), no suspension or cancellation
        of any of them is threatened to the knowledge of the Company, and
        with the exception of possible novation requirements for
        contracts with the U.S. Department of Defense and U.S. Department
        of Energy, the filing of the Articles of Merger and the
        consummation of the Merger will not adversely affect the validity
        or effectiveness of, and will not require, for retention thereof
        after such change of ownership, the consent or approval of any
        party to, or any other person or governmental agency having
        jurisdiction of, any such permit, license, franchise, concession,
        zoning variance, approval, authorization or order.  The Company
        has no knowledge of any fact or circumstance which would prevent,
        limit or restrict the Company from continuing to operate its
        business in the present manner, and no new material requirements
        pertaining to the manner of operating its specific business (not
        businesses in general) have been issued or announced by any
        governmental authority during the past year, nor are there any
        disputes pending between the Company and any governmental
        authority about the Company's operations as presently being
        conducted.  The Company has furnished or made available to Thermo
        all reports and applications filed by the Company with any
        governmental agency in the last three years.

             (l)  Patents; Trademarks.  Except for rights reserved by the
        U.S. Government for its sole noncommercial use under government
        contracts with the Company, the Company solely owns or has the
        exclusive right to use, free and clear of any obligation of
        payment, encumbrance, lien or claim, all patents, patent and
        know-how licenses, trademarks, trade names, service marks, brand
        names and copyrights, and registrations and applications
        therefor, used in the conduct of its business or the use of which
        is necessary for its business as now being conducted (the
        "Intangibles").  Set forth on the Disclosure Schedule is a
        complete list and summary description of all Intangibles and
        licenses (including, but not limited to, rights reserved by the
        U.S. Government with respect to specific Intangibles),
        sublicenses or other rights entered into or granted by or to the
        Company with respect thereto.  The Company owns or possesses
        adequate rights to use, free and clear of any obligation of
        payment, encumbrance, lien or claim, all inventions, technology,
        technical know-how, processes, designs, trade secrets, vendor and
        customer lists and other confidential information required for or
        used in its business.  To the extent that the Company has
        provided to the U.S. Government any trade secrets, know how, or
        proprietary data, the Company has marked such trade secrets, know
        how, and proprietary data with adequate restrictive legends which
        identify such as either "restricted computer software" or
        "limited rights data", as those terms are defined in the Federal

        Acquisition Regulations ("FAR") at Subpart 27.4.  To the extent
        that the Company has provided to any third party, other than the
        U.S. Government, any trade secrets, know how, or proprietary
        data, such information has been provided subject to an adequate
        non-disclosure agreement.  No person has made any claim or demand
        upon the Company pertaining to, and no proceeding is pending, or
        so far as is known, threatened, which challenges (i) the rights
        of the Company in respect of any Intangibles or (ii) the rights
        of the Company to any confidential information or trade secrets
        used in the conduct of its business.  No Intangible owned or used
        by the Company is subject to any order, ruling, decree, judgment
        or stipulation by or with any court, arbitrator or administrative
        agency which is adverse to the Company's business.  No person has
        made any claim or demand, nor is the Company aware that it has,
        infringed, or engaged in the unauthorized use of, any patent,
        trademark, trade name, service mark, brand name or copyright, or
        any invention, technology, technical know-how, process, design,
        trade secret or other intellectual property of another.  The
        Company is not aware of any infringement or unauthorized use by a
        third party of any patent, trademark, trade name, service mark,
        brand name or copyright, or any invention, technology, technical
        know-how, process, design, trade secret or other intellectual
        property owned or used by the Company.  Each technical or
        managerial employee of the Company is bound by the terms of an
        Employee Patent and Confidential Information Agreement or similar
        agreement, a copy of which has been supplied to Thermo. 

             (m)  Government Property; Accounting for Government
        Contracts.  The Disclosure Schedule contains an accurate list of
        the type and location of each item of property owned or furnished
        directly or indirectly by the U.S. Government or by
        non-government customers to be used by the Company in connection
        with the performance of prime contracts or subcontracts for the
        U.S. Government or any agency or department thereof or, as the
        case may be, for other non-government customers; in each case
        where the original acquisition price exceeded $100,000.  All such
        property is present at the location so indicated, is in as good
        condition as when originally furnished, except for ordinary wear
        and tear, and is being accounted for pursuant to applicable
        Federal regulations or customer requirements.  The Company has
        not fraudulently claimed reimbursement under contracts with the
        U.S. Government for costs which are unallowable, including costs
        specifically allowed by FAR Part 31, entitled "Contract Cost
        Principles and Procedures."  The Company's costs accounting
        system complies with generally accepted accounting principles,
        consistently applied, and the Cost Accounting Standards, as
        promulgated by the Cost Accounting Standards Board and reflected
        in Appendix B to the FAR.  Moreover, the Company has not made any
        changes to its accounting practices that would require submission
        of a cost impact proposal to the U.S. Government and no cost
        impact proposal has been requested by the U.S. Government.  There
        are no pending, or to the Company's best knowledge, threatened
        audits by the Defense Contracts Audit Agency or other government
        audit authority under which allowance and allocation of cost

        and/or accounting for cost is at issue or that could lead to the
        disallowance of repayment of any monies already received.

             (n)  Insurance.  To the best knowledge of the Company, the
        Company is not in default with respect to any provisions of any
        policy of general liability, fire, title or other form of
        insurance held by it.  The Company is current in the payment of
        all premiums due or has reserved for such premiums due on such
        insurance, and has not failed to give any notice or present any
        claim thereunder in due and timely fashion, except for claims
        that are immaterial in both the nature of the claim and in the
        amount of such claim.  The Company maintains insurance on all of
        its assets and its business (including products liability
        insurance) from insurers which to its knowledge are financially
        sound and reputable, in amounts and coverages and against the
        kinds of risks and losses reasonably prudent to be insured
        against by corporations engaged in the same or similar
        businesses.  All policies of insurance held by the Company are
        listed on the Disclosure Schedule.  No basis exists which would
        jeopardize the coverage under any such insurance.  Under the
        terms of the policy relating thereto, no such insurance will be
        automatically terminated or canceled by reason of the execution,
        delivery and performance of this Agreement or the consummation of
        the transactions contemplated hereby.

             Agreement, or in the particular location in this Agreement,
             is relevant.

             Except as disclosed in the Disclosure Schedule:

             The Company does not maintain or contribute to any Pension
        Plan or any Welfare Plan, nor has the Company or any of CRC's
        ERISA Affiliates ever had, an obligation to contribute to any
        Multiemployer Plan.  All Pension Plans and Welfare Plans of the
        Company have been administered in compliance with their terms,
        ERISA and, where applicable, the Code.  The Company has applied
        to the Internal Revenue Service for a favorable determination
        letter with respect to the qualification of each such Pension
        Plan which is intended to qualify under Section 401(a) of the
        Code and the exemption of any corresponding trust.  A copy of
        each such application has been furnished to Thermo, and the
        Company has no reason to believe that such favorable
        determination letters will not be issued in the ordinary course.
        With respect to each Pension Plan:  (1) there is no fact,
        including, without limitation, any Reportable Event, that exists
        that would constitute grounds for termination of such Plan by the
        PBGC or for the appointment by the appropriate United States
        District Court of a trustee to administer such plan, in each case
        as contemplated by ERISA; (2) neither the Company nor any
        fiduciary, trustee or administrator of any Pension Plan or
        Welfare Plan has engaged in any Prohibited Transaction that could
        subject the Company to any tax or any penalty imposed by ERISA or
        the Code; (3) the Company has no liability to the PBGC (other
        than for payment of premiums); and (4) there is no Accumulated
        Funding Deficiency with respect to any Pension Plan maintained by
        the Company or any of CRC's ERISA Affiliates, whether or not
        waived.  

             No Pension Plan or Welfare Plan, the Company or any of CRC's
        ERISA Affiliates, or any "party in interest" or "disqualified
        person" (as such terms are defined in Section 3 of ERISA and
        Section 4975 of the Code) with respect to any Pension Plan or
        Welfare Plan has taken any action including the making of any
        investment, or failed to take any action, that could subject any
        of them or any other person to any liability for any tax or for
        breach of fiduciary duty with respect to or in connection with
        any Pension Plan or Welfare Plan.  No Pension Plan or Welfare
        Plan, administrator or fiduciary of any Pension Plan or Welfare
        Plan, or the Company has any liability under any provision of any
        applicable law by reason of any communication or failure to
        communicate with respect to or in connection with any Pension
        Plan or Welfare Plan, or any filing or failure to file with any
        governmental entity.  No Pension Plan or Welfare Plan,
        administrator or fiduciary of any Pension Plan or Welfare Plan,
        or the Company or any of CRC's ERISA Affiliates has any liability
        to any plan participant, beneficiary or other person under any
        provision of any applicable law by reason of any payment of
        benefits or other amounts or failure to pay benefits or any other
        amounts, or by reason of any credit or failure to give credit for
PAGE
<PAGE>





        any benefits or rights (such as, but not limited to, vesting
        rights) with respect to benefits under or in connection with any
        Pension Plan or Welfare Plan, other than benefit claims in the
        normal administration of each Pension Plan or Welfare Plan.  The
        Company is not delinquent or in arrears on any amounts owed to,
        or with respect to any contributions under, any Pension Plan or
        Welfare Plan.  No person is a participant in or eligible for
        participation (without regard to age or service) in, any Pension
        Plan or Welfare Plan who is not a present or former employee of
        the Company or a beneficiary of such Pension Plan or Welfare
        Plan.  Except as may be required by the Consolidated Omnibus
        Budget Reconciliation Act of 1985 ("COBRA"), none of the Pension
        Plans or Welfare Plans provides for continuing accrual of
        benefits or coverage for any participant or beneficiary of a
        participant after such participant's termination of employment
        with the Company.

             Except to the extent COBRA requires the Company to offer
        health insurance and the Company incurs administrative costs,
        there are no unfunded obligations under any Pension Plan or
        Welfare Plan providing benefits after termination of employment
        to any employee of the Company (or beneficiary thereof),
        including without limitation retiree health coverage and deferred
        compensation.  There has been no Plan Termination that has
        occurred during the five-year period ending on the date hereof.
        The Company has no liability incurred under Title IV of ERISA by
        the Company with respect to any Pension Plan maintained by a
        trade or business (whether or not incorporated) which is under
        common control with, or part of a controlled group of
        corporations with, the Company, within the meaning of Sections
        414(b) or (c) of the Code.  No event has occurred and no
        condition exists with respect to any Pension Plan or Welfare Plan
        that would subject the Company to any tax under Section 4972,
        4977, 4979 or 4980B of the Code or to a fine under ERISA Section
        502(c) with respect to any such plan.  No Welfare Plan is funded
        with a trust or other funding vehicle, other than insurance
        policies.  No Welfare Plan or Pension Plan, plan documentation or
        agreement, summary plan description or other written
        communication distributed to employees prohibits the Company from
        amending or terminating any such plan.  There has occurred no
        Complete Withdrawal or Partial Withdrawal with respect to any
        Multiemployer Plan that could cause the Company to incur any
        liability under or as a result of ERISA other than to the extent
        previously paid or fully provided for in the Balance Sheet, and
        all payments required to be made to any such Plan by the Company
        under any applicable collective bargaining agreements have been
        made.  As of the date of the Balance Sheet, the Company had no
        liability in connection with any Pension Plan, Welfare Plan or
        other employee benefit plan which was not fully provided for on
        the Balance Sheet.  There are no actions, arbitration's or claims
        pending or threatened with respect to any Pension Plan, Welfare
        Plan or other employee benefit plans or any fiduciary or sponsor
        thereof.

             (x)  Brokers and Finders.  The Company has not employed any

        or devices.

             (aa)  No Termination of Relationship.  As of the date
        hereof, the Company is unaware that any relationship between the
        Company and a distributor, customer, supplier, lender, employee
        or other person may be terminated or adversely affected as a
        result of the Merger.

             (bb)  Consummation of Coleman Laboratories Transaction.
        Effective as of the Closing Date, CRC will consummate the Coleman
        Laboratories Transaction, and the Company will thereafter have no
        obligation to make any further investments in Dr. Mohammad Walid
        Katoot ("Dr. Katoot"), MK Industries, Inc. ("MKI"), Coleman
        Laboratories, Ltd. ("Coleman L.P.") and/or Coleman Laboratories,
        Inc. ("Coleman Laboratories"). 

             (cc)  Compliance with the Securities Act.  The Company has
        delivered to Thermo a letter identifying all persons who are
        "affiliates" of it for purposes of Rule 145 under the Securities
        Act of 1933, as amended (the "Securities Act").  The Company has
        caused each person who it identified as an "affiliate" to deliver
        to Thermo, and each "affiliate" has, concurrently with the
        signing of this Agreement, signed an Affiliate Agreement
        providing that such person has no plan or intention and will not
        sell, pledge, transfer or otherwise dispose of the CRC Shares or
        in any way reduce their risk relative to any such shares, until
        such time as financial results covering at least 30 days of
        combined operations of Thermo and CRC have been published within
        the meaning of Section 201.01 of the Codification of Financial
        Reporting Policies of the Commission and except in compliance
        with the applicable provisions of the Securities Act, and the
        rules and regulations thereunder. 

             (dd)  Pooling Accounting.  The Company and the Shareholders
        have taken no actions that would prevent Thermo from accounting
        for the Merger as a pooling-of-interests for accounting purposes.

             (ee)  Continuity of Interest.  To the best of the Company's
        knowledge, there is no plan or intention on the part of the
        Shareholders to sell, exchange or otherwise dispose of a number
        of shares of Thermo Shares received in the Merger that would
        reduce the Shareholders' ownership of Thermo stock to a number of
        shares having a value, as of the Effective Date, of less than
        fifty (50%) percent of the value of all of the formerly
        outstanding stock of CRC as of the same date.  For purposes of
        this representation, shares of CRC common stock surrendered by
        dissenters or exchanged for cash or in lieu of fractional shares
        of Thermo Common Stock will be treated as outstanding CRC common
        stock on the Effective Date.  Moreover, shares of CRC common

        stock and shares of Thermo Common Stock held by the Shareholders
        and otherwise sold, redeemed, or disposed of prior or subsequent
        to the Merger will be considered in making this representation.
        The Company has caused each person who it identified as an
        "affiliate" to deliver to Thermo and each "affiliate" has,
        concurrently with the signing of this Agreement, signed an
        Affiliate Agreement.

             (ff)  Information About the Company in the Registration
        Statement.  The information in Thermo's Registration Statement on
        Form S-4 registering the issuance of the Thermo Shares with the
        Commission (the "Registration Statement") that pertains to the
        Company and its Shareholders, directors and officers (i) does not
        contain any untrue statement of material fact or omit to state a
        material fact required to be stated therein or necessary to make

        material respects with the Securities Act.  The Company has not

        "offer for sale" or "sale" of Thermo Shares within the meaning of
        Rule 145 under the Securities Act.  The description in the
        Registration Statement of the tax consequences to the
        Shareholders and Optionholders of the transactions contemplated
        herein is accurate and complete in all material respects.

        Agreement all information as to the condition (financial or

        of the Company, material to a determination by a reasonable buyer
        to enter into this Agreement and to consummate the transactions
        contemplated hereby.

             (ii)  Statements True and Correct; Further Representations
        and Warranties.  This Agreement (including the Exhibits and any
        documents delivered pursuant hereto) does not contain any untrue

        the full amount of all damages (as defined below) suffered by it
        as a direct or indirect result of:

                  (i)  the inaccuracy of any representation or warranty
             made by Thermo in or pursuant to this Agreement, in the form
             and to the extent so made, or the omission of any material
             fact relating thereto; and

                  (ii)  any failure by Thermo or Acquisition to perform
             any obligation or comply with any covenant or agreement
             specified in this Agreement or in any other document
             executed at the Closing.

             (b)  For the purpose of this Agreement, the term "damages"
        shall be determined and computed by reference to the actual
        economic loss to CRC (and not just by reference to any effect on
        the value of the shares of CRC) and shall be deemed to include
        all losses, liabilities, expenses or costs incurred by the CRC,
        including reasonable attorney's fees.

             (c)  The right of CRC to be indemnified pursuant to Section
        4.9 (i) shall not apply until the sum of the damages suffered by
        CRC on a cumulative basis equals or exceeds $500,000, at which
        point Thermo shall become liable for all damages, not just
        amounts in excess of $500,000, and (ii) shall be only for claims
        that are asserted by CRC before the first anniversary of the
        Closing Date.  In no event shall Thermo's liability hereunder
PAGE

        exceed $__________.  Notwithstanding the foregoing, this Section
        4.9(c) shall not apply in the event Thermo has actual knowledge
        of a breach of a representation or warranty.

             Section 7.7.  Severability.  If any provision of this
        Agreement shall be declared void or unenforceable by any judicial
        or administrative authority, the validity of any other provision
        shall not be affected thereby.

             Section 7.8.  Counterparts.  This Agreement may be executed
        in several counterparts, each of which shall be deemed an
        original, but all of which together shall constitute one and the
        same instrument.

             Section 7.9.  No Solicitation.  Prior to the earlier of (i)
        the Closing or (ii) the termination of this Agreement, the
        Company will not, directly or indirectly, solicit, encourage or
        initiate any discussions with, or negotiate or otherwise deal
        with, or provide any information to, any person other than Thermo
         concerning any merger, sale of substantial assets or similar
        transactions involving the Company or any sale of its capital
        stock.

             Section 7.10.  Relief.  In the event of a breach of the
        provisions of this Agreement by a party to this Agreement prior
        to the Closing, in addition to any other rights and remedies that
        party may have under law or in equity, the non-breaching party
        shall have the right to specific performance and injunctive
        relief, it being acknowledged and agreed that money damages will
        not provide an adequate remedy.  In the event litigation is
        maintained by a party to this Agreement against any other party
        to enforce this Agreement or to seek any remedy for breach, then
        the party prevailing in such litigation shall be entitled to
        recover from the non-prevailing party reasonable attorneys' fees
        and costs of suit.

             Section 7.11.  Exhibits.  The Exhibits attached hereto and

                   INDEMNIFICATION AND STOCK ESCROW AGREEMENT


             INDEMNIFICATION AND STOCK ESCROW AGREEMENT, dated as of
        February __, 1995 by and among Thermo Electron Corporation, a
        Delaware corporation ("Thermo"), Coleman Research  Corporation, a
        Florida corporation ("CRC"), Thomas J. Coleman (the "Shareholder
        Representative"), and The First National Bank of Boston, as
        escrow agent ("Escrow Agent").

             WHEREAS, Thermo and CRC have entered into an Agreement and
        Plan of Merger dated January __, 1995 (the "Merger Agreement"),
        contemplating the acquisition by Thermo of all of the issued and
        outstanding shares of capital stock of CRC (the "CRC Shares");
        and

             WHEREAS, the parties desire that certain shares of Thermo
        common stock to be issued pursuant to the Merger be received,
        held and disposed of by the Escrow Agent subject to the terms and
        conditions herein expressed;

             WHEREAS, the execution and delivery of this Agreement is a
        condition precedent to the obligation of Thermo to consummate the
        transactions contemplated by the Merger Agreement;

             NOW, THEREFORE, as an inducement to Thermo to consummate the
        transactions contemplated by the Merger Agreement and in
        consideration of these premises and other good and valuable
        consideration, the parties hereto hereby agree as follows:

             Section 1.  Definitions.  Capitalized terms used herein
        which are defined in the Merger Agreement but not defined herein
        shall have the same meanings herein as therein.  "Escrow
        Termination Date" shall mean February __, 1996.

             Section 2.  Consent of Shareholders.  By virtue of the
        Shareholders' approval of the Merger Agreement, the Shareholders
        have, without any further act of any Shareholder, consented to:
        (i) the establishment of the escrow account to secure CRC's
        indemnification obligations under Section 4 of this Agreement in
        the manner set forth herein, (ii) the appointment of the
        Shareholder Representative as their representative for purposes
        of this Agreement and as attorney-in-fact and as agent for and on
        behalf of each Shareholder, the taking by the Shareholder
        Representative of any and all actions and the making of any
        decisions required or permitted to be taken or made by him under
        this Agreement and (iii) all of the other terms, conditions and
        limitations of this Agreement.

             Section 3.  Deposit of Escrow Property.   Thermo hereby
        deposits with Escrow Agent, and Escrow Agent hereby acknowledges
PAGE

        receipt of, a stock certificate evidencing ___________ (______)
        shares of Thermo's common stock, $1.00 par value per share (the
        "Escrowed Shares").  Such certificate has been issued in the name
        of Escrow Agent or its nominee.  

             In case any distribution (except a cash dividend paid out of
        earned surplus) or stock dividend shall be made on or in respect
        of the Escrowed Shares, or any property shall be distributed upon
        or with respect to the Escrowed Shares pursuant to the
        recapitalization, liquidation or reclassification of the capital
        structure of Thermo or pursuant to the merger, consolidation or
        reorganization of Thermo, the money, stock or property so
        distributed or paid shall be delivered to and held by Escrow
        Agent hereunder.  Such money, stock and property, together with
        the Escrowed Shares, are sometimes referred to hereinafter as the
        "Escrow Property."  Shareholders shall be entitled to receive, in
        proportion to their respective number of Escrowed Shares, all
        cash dividends paid in respect of the Escrowed Shares out of the
        earned surplus of Thermo.

             While the Escrowed Shares are held by Escrow Agent,
        Shareholders shall be entitled to direct Escrow Agent as to how
        to vote the Escrowed Shares, in proportion to their respective
        number of Escrowed Shares, with respect to matters placed before
        the shareholders of Thermo, and Escrow Agent shall vote
        accordingly.

             Section 4.  Holding and Distribution of Escrow Property.
        Thermo and Acquisition (including the Surviving Corporation after
        the Merger) upon their demand shall be indemnified for the full
        amount of all damages (as defined below) suffered by them as a
        direct or indirect result of:

                       (i)  the inaccuracy of any representation or
                  warranty made by CRC in or pursuant to the Merger
                  Agreement, in the form and to the extent so made, or
                  the omission of any material fact relating thereto;

                       (ii)  any failure by CRC to perform any obligation
                  or comply with any covenant or agreement specified in
                  the Merger Agreement or in any other document executed
                  at the Closing; and 

                       (iii)  any other claims (including, without
                  limitation, claims alleging death or injury to persons
                  or damage to property caused by, or resulting from, any
                  defect or claimed defect in or with respect to products
                  of CRC (whether based in tort or contract), any tort,
                  default in the performance or breach of any contract or
                  commitment, or for consequential, special or punitive
                  damages) for all conditions, acts or failures to act of
                  CRC or other occurrences prior to or on the Closing
                  Date or resulting from or caused by any product
                  purchased for resale, manufactured or sold, or service
PAGE
<PAGE>





                  provided, by CRC prior to the Closing Date; all bodily
                  injury and property damage arising after the Closing
                  Date out of continuous or repeated exposure to
                  substantially the same general conditions in existence
                  on or before the Closing Date shall be considered as
                  arising out of one occurrence prior to the Closing
                  Date.

             For the purpose of this Agreement, the term "damages" shall
        be determined and computed by reference to the actual economic
        loss to Thermo, Acquisition and/or the Surviving Corporation (and
        not just by reference to any effect on the value of the shares of
        the Surviving Corporation) and shall be deemed to include all
        losses, liabilities, expenses or costs incurred by the Surviving
        Corporation, including reasonable attorney's fees.

             Thermo shall give the Shareholder Representative notice of
        any claim, action or proceeding by a third party which is
        reasonably likely to result in a claim for indemnification under
        this Section 4.  Thermo shall have the right to defend, contest,
        protest and otherwise control the resolution of any such claim,
        action or proceeding (unless Thermo decides in good faith not to
        contest such claim and such claim, action or proceeding relates
        to a matter which, if adversely determined, would have no impact
        on the Surviving Corporation's liability in another proceeding,
        goodwill or reputation or on the future conduct by the Surviving
        Corporation of its business or on its Tax or accounting
        positions, in which case the next paragraph shall apply), but
        shall keep the Shareholder Representative apprised of material
        developments.  The Shareholder Representative shall have the
        right to participate in any such legal proceeding, subject to
        Thermo's right of control thereof, at the expense of the
        Shareholder Representative by counsel of the Shareholder
        Representative's choice.  Thermo, acting in good faith, shall
        have the right in its sole discretion to settle any such claim.

             If the claim, action or proceeding is one which, if
        adversely determined, would have no impact on Thermo's or the
        Surviving Corporation's liability in another proceeding, goodwill
        or reputation or on the future conduct by the Surviving
        Corporation of its business or on its Tax or accounting
        positions, then (i) the Shareholder Representative shall have the
        right, at his expense, to defend, contest, protest and otherwise
        control the resolution thereof, but shall keep Thermo apprised of
        material developments and (ii) Thermo shall have the right to
        participate in any such legal proceeding, subject to the
        Shareholder Representative's right of control thereof, at
        Thermo's expense and with counsel selected by Thermo.

             The Shareholders hereby designate and appoint Mr. Thomas J.
        Coleman (the "Shareholder Representative") as their
        representative and attorney-in-fact through whom all actions by
        the Shareholders relating to this Agreement after the Closing
        Date, including those acts as are required, authorized or
PAGE
<PAGE>





        contemplated by this Agreement with respect to the settlement of
        a claim or the defense thereof, shall be made or directed, and
        hereby acknowledge that the Shareholder Representative shall be
        the only person authorized to take any action so required,
        authorized or contemplated by this Agreement on behalf of the
        Shareholders.  The Shareholders further acknowledge that the
        foregoing appointment and designation shall be deemed to be
        coupled with an interest and shall survive the disability, death
        or incompetency of any Shareholder.  The other parties hereto are
        and will be entitled to rely on any action so taken or any notice
        given by the Shareholder Representative and entitled and
        authorized to give notices only to the Shareholder Representative
        for any notice contemplated by this Agreement to be given any
        such person.  The Shareholder Representative shall serve without
        compensation but shall be reimbursed for his reasonable
        out-of-pocket expenses from the Escrow Property.  The Shareholder
        Representative shall have the right to sell Escrow Property in
        order to obtain funds to pay such expenses.  The Shareholder
        Representative shall furnish reports as to the status of the
        escrow to the Shareholders as and when Escrowed Shares are
        released from the escrow or claims are paid.  Thermo, Acquisition
        or the Surviving Corporation shall not have any liability or
        responsibility to the Shareholder Representative. 

             The Shareholder Representative shall receive and deliver
        notices on behalf of the Shareholders and take all such action as
        in the Shareholder Representative's discretion may be necessary,
        appropriate, permitted or advisable to be taken under the terms
        of this agreement in order to consent to, pay, contest,
        arbitrate, litigate or settle any claim or alleged claim asserted
        hereunder.

             The Shareholder Representative shall not be personally
        liable to the other Shareholders for any action taken, suffered
        or omitted by him in good faith and reasonably believed by him to
        be authorized or within the discretion of the rights or powers
        conferred upon him by this Agreement.

             In acting as representative of the Shareholders, the
        Shareholder Representative may rely upon, and shall be protected
        in acting or refraining from acting upon, an opinion of counsel,
        certificate of auditors or other certificate, statement,
        instrument, opinion, report, notice, request, consent, order,
        arbitrator's award, appraisal, bond or other paper or document
        reasonably believed by him to be genuine and to have been signed
        or presented by the proper party or parties.  The Shareholder
        Representative may consult with counsel and any advice of such
        counsel shall be full and complete authorization and protection
        in respect to any action taken or suffered or omitted by him in
        such capacity in good faith and in accordance with such opinion
        of counsel.  The Shareholder Representative may perform his
        duties as Shareholder Representative either directly or by or
        through his agents or attorneys and the Shareholder
        Representative shall not be responsible to the other Shareholders
PAGE
<PAGE>





        for any misconduct or negligence on the part of any agent or
        attorney appointed with reasonable care by him hereunder.

             Upon receiving notice of the death or incapacity of the
        Shareholder Representative, the Shareholders shall by majority
        vote (based on their number of CRC Shares held immediately prior
        to the Closing Date) appoint a successor to fill the vacancy.
        The Shareholders may by such a majority vote remove the
        Shareholder Representative with or without cause and appoint a
        successor, provided that notice thereof is given by the new
        Shareholder Representative to each of the other parties hereto.
        The Shareholder Representative may resign if, and only if, he is
        simultaneously replaced with a substitute Shareholder
        Representative reasonably acceptable to Thermo.

             Section 5.  Limitation of Liability.  The right of Thermo,
        Acquisition and the Surviving Corporation to be indemnified
        pursuant to Section 4 shall be (a) limited to the return to
        Thermo of the Escrow Property, (b) shall not apply until the sum
        of the damages suffered by Thermo, Acquisition and the Surviving
        Corporation on a cumulative basis equals or exceeds $500,000, at
        which point the Company shall become liable for all damages, not
        just amounts in excess of $500,000, and (c) only for claims that
        are asserted by Thermo, Acquisition or the Surviving Corporation
        before the first anniversary of the Closing Date.
        Notwithstanding the foregoing, this Section 5 shall not apply in
        the event the Company has actual knowledge of a breach of a
        representation or warranty.

             Section 6.  Escrow Account.   It is intended that the assets
        held in escrow as above provided shall facilitate Thermo's and
        the Surviving Corporation's ability to recover amounts to which
        they are entitled as a result of misrepresentations, breaches of
        warranties and breaches of covenants contained in the Merger
        Agreement or this Agreement and to satisfy claims of Thermo and
        Acquisition arising as a result of the Merger Agreement or this
        Agreement.  Accordingly, and to the extent necessary to provide
        such protection to Thermo and the Surviving Corporation, property
        held in escrow hereunder shall be available to satisfy claims of
        Thermo and the Surviving Corporation under this Agreement to the
        extent provided herein.  In the event the Escrowed Property is
        insufficient to pay all damages to Thermo, Acquisition and the
        Surviving Corporation, including by virtue of the expiration of
        the escrow period, no Shareholder shall be liable under this
        Agreement to pay any amount in addition to such Shareholder's
        proportionate share of the Escrow Property claimed by Thermo
        prior to the Escrow Termination Date.  Once the Escrow Property
        or balance thereof is released to the Shareholders, Thermo,
        Acquisition and the Surviving Corporation have no right to
        recover damages from the Shareholders in the absence of actual
        knowledge of a breach of a representation or warranty.

             Section 7.  Registration of Claims.  In the event that
        Thermo or the Surviving Corporation asserts any claim for
PAGE
<PAGE>





        indemnification against the Escrowed Shares, it shall deliver to
        Escrow Agent and the Shareholder Representative a written notice
        thereof (the "Notice of Claim") setting forth (a) a demand for
        payment of a specified amount from the Escrowed Shares or, if
        such amount can not be specified, the basis upon which the amount
        would be determined and (b) a description of the asserted claim
        and the basis thereof, and Thermo shall deliver to the
        Shareholder Representative thereafter such other information as
        may be reasonably requested by the Shareholder Representative to
        evaluate the asserted claim.  It is understood and agreed among
        the parties hereto that Thermo's and the Surviving Corporation's
        right to assert claims for indemnification under this Agreement
        is limited to those matters set forth in this Agreement, although
        the Escrow Agent shall have no obligation to determine or verify
        whether such condition has been met.

             Section 8.  Payment of Amounts from Escrow Property Upon
        Demand Without Objection.  If Thermo delivers to the Shareholder
        Representative and Escrow Agent a Notice of Claim pursuant to
        Section 4 hereof and if no written objection to such demand is
        received by Escrow Agent and Thermo, from the Shareholder
        Representative, within 30 days following the delivery of such
        Notice of Claim to Escrow Agent and the Shareholder
        Representative, then Escrow Agent shall pay the claim out of the
        Escrow Property by forthwith endorsing and delivering to Thermo
        the certificates representing the Escrowed Shares.  Thermo shall
        be entitled to retain that number of Escrowed Shares which, when
        multiplied by the Per Share Value (as defined below), shall equal
        the amount of the claim as provided in Section 4 hereof;
        provided, however, that Notices of Claim must be delivered before
        the Escrow Termination Date and Thermo may not retain more than
        the Escrowed Shares.  Thermo shall return one or more
        certificates for the excess Escrowed Shares to Escrow Agent for
        continued holding hereunder.  To the extent the value (calculated
        on the basis of the Per Share Value, regardless of actual market
        value at the time) of the Escrowed Shares retained by Thermo is
        less than the amount of the claim, Escrow Agent shall also
        transfer to Thermo other Escrow Property, if any, in addition to
        the Escrowed Shares.

             The Per Share Value shall be $__________ per share,
        representing the reported closing price of Thermo's Common Stock
        on the New York Stock Exchange on February __, 1995.

             Section 9.  Payment of Amounts from Escrow Property After
        Notice of Objection.  If Thermo delivers to the Shareholder
        Representative and Escrow Agent a Notice of Claim pursuant to
        Section 4 hereof, and if the Shareholder Representative shall
        give written objection thereto to Escrow Agent and Thermo prior
        to the expiration of the 30-day period specified in Section 8,
        Escrow Agent shall make no payment in respect of the demand set
        forth in such Notice of Claim until it shall have received one of
        the following:
PAGE
<PAGE>





             (a)  written instructions signed on behalf of both Thermo
        and the Shareholder Representative; or

             (b)  a final order of a court having jurisdiction over the
        asserted claim, after expiration of any applicable appeal period.

             Upon receipt of any such instructions or order, Escrow Agent
        shall pay such amount from the Escrow Property to Thermo as may
        be directed by such instructions or order; provided, however that
        (i) the limitations set forth in Section 8 hereof on the number
        of Escrowed Shares retainable by Thermo shall also apply to
        claims paid under this Section 9, and (ii) all Escrowed Shares
        delivered to Thermo shall be valued on the basis of the Per Share
        Value, regardless of the actual market price of Thermo's Common
        Stock on the date such shares are delivered to Thermo.  If the
        final order of a court having jurisdiction over the asserted
        claim, after expiration of any applicable appeal period, upholds
        the Shareholder Representative's objection to the Escrow Agent,
        Thermo shall reimburse the Escrow Agent for reasonable attorneys'
        fees and expenses paid from the Escrow Property to pursue the
        objection.

             Section 10.  Payment of Escrow Property to Shareholders.  On
        the Escrow Termination Date, Escrow Agent shall deliver to Thermo
        and the Shareholder Representative a statement of the remaining
        balance, if any, of the Escrow Property (calculated on the basis
        of the Per Share Value, regardless of the actual market price of
        Thermo's Common Stock at that time), and the total amount of all
        claims registered pursuant to Section 7 hereof and not
        theretofore resolved and paid (the excess, if any, of such
        remaining balance over the total amount of such claims shall be
        referred to as the "Final Escrow Balance").  Thermo and the
        Shareholder Representative shall review the accuracy of the Final
        Escrow Balance and notify Escrow Agent within 30 days of the
        foregoing statement of any asserted discrepancy.  Upon the
        expiration of the 30-day period after receipt by Thermo and the
        Shareholder Representative of such statement, and if Escrow Agent
        has not been notified of any discrepancy by Thermo or the
        Shareholder Representative within the 30-day period specified in
        the preceding sentence, Escrow Agent shall deliver to each
        Shareholder Escrow Property representing such Shareholder's share
        of the Final Escrow Balance, free and clear of the escrow created
        by this Agreement.  After the last registered claim shall have
        been resolved pursuant to Section 8 and Section 9 hereof, as the
        case may be, and paid, the remaining balance, if any, of the
        Escrow Property shall be delivered by Escrow Agent to
        Shareholders, free and clear of the escrow created by this
        Agreement; provided, however, that upon the disposition of any
        such claim prior to the disposition of all such claims Escrow
        Agent shall deliver to Shareholders the Escrow Property in excess
        of the amount of the remaining aggregate claims as determined
        above.  All payments by Escrow Agent to Shareholders pursuant to
        this Agreement shall be made in proportion to the Shareholders'
        respective interests in the Escrowed Shares.

             Section 11.  Responsibility of Escrow Agent.  Escrow Agent
        may act upon any instrument or other writing believed by it in
        good faith to be genuine and to have been signed or presented by
        the proper person and shall not be liable to any party hereto in
        connection with the performance of its duties hereunder, except
        for its own negligence or willful misconduct.  Escrow Agent's
        duties shall be determined only with reference to this Escrow
        Agreement and applicable laws and Escrow Agent is not charged
        with knowledge of, or any duties or responsibilities in
        connection with, any other document or agreement.  If in doubt as
        to its duties and responsibilities hereunder, Escrow Agent may
        consult with counsel of its choice and shall be protected in any
        action taken or omitted in connection with the advice or opinion
        of such counsel.  

             If any party to this Agreement disagrees on anything
        connected with this escrow (1) Escrow Agent will not have to
        settle the matter, (2) Escrow Agent may wait for a settlement by
        appropriate legal proceedings or other means it may require, and
        in such event it will not be liable for interest or damage, (3)
        if Escrow Agent intervenes in or is made a party to any legal
        proceedings, it will be entitled to such reasonable compensation
        for services, costs and attorney's fees as the court may award
        and (4) Escrow Agent is entitled to hold documents and assets
        deposited in this escrow pending settlement of the disagreement
        by any of the above means.

             Escrow Agent is to act as a depositary agent only and is
        hereby relieved of any liability in connection with any
        representations made by the other parties hereto or any of their
        agents.  Escrow Agent shall not be responsible for and shall not
        be under a duty to examine any other agreement.

             Section 12.  Indemnification and Fees of Escrow Agent.  In
        consideration of its acceptance of the appointment as Escrow
        Agent, Thermo shall  indemnify and hold Escrow Agent harmless as
        to any liability incurred by it to any other person, firm or
        corporation by reason of its having accepted the same or in
        carrying out any of the terms hereof, and to reimburse the Escrow
        Agent for all its out-of-pocket expenses, including, among other
        things, reasonable counsel fees and court costs, incurred by
        reason of its position hereunder or actions taken pursuant
        hereto, except in the event of the negligence or willful
        misconduct of Escrow Agent.  The fees and charges set forth below
        for the services of Escrow Agent will be considered compensation
        for Escrow Agent's ordinary services as contemplated by this
        Agreement.  In the event the conditions of the escrow are not
        promptly fulfilled or Escrow Agent renders any service not
        provided for in this Agreement or there is any assignment of any
        interest in the subject matter of this escrow or modification of
        any interest or if any controversy arises in connection with it,
        Escrow Agent will be reasonably compensated for such
        extraordinary services, and will be reimbursed for all reasonable
PAGE
<PAGE>





        costs, attorney's fees and expenses occasioned thereby, which
        compensation, costs, fees and expenses shall be paid by Thermo.  

             Escrow Agent's initial acceptance fee is $1,250 and Escrow
        Agent's annual fee hereunder is $1,750, which fees are
        nonrefundable and shall be paid in advance by Thermo.

             Section 13.  Resignation of Escrow Agent.  Escrow Agent may
        resign and be discharged from its duties hereunder at any time by
        giving not less than 60 days prior written notice of such
        resignation to Thermo and the Shareholder Representative, which
        notice shall specify the date when such resignation shall take
        effect.  Upon such notice, Thermo and the Shareholder
        Representative shall appoint a successor escrow agent.  If Thermo
        and the Shareholder Representative are unable to agree upon a
        successor escrow agent within 30 days after such notice, Escrow
        Agent may apply to a court of competent jurisdiction for such
        appointment.  Escrow Agent shall continue to serve until its
        successor delivers to Thermo and the Shareholder Representative a
        duly executed instrument of acceptance of the terms and
        conditions of this Agreement and receives the Escrow Property.

             Section 14.  Investments.  Escrow Agent shall invest the
        cash portion of the Escrow Property, if any, in money market
        accounts at The First National Bank of Boston.  Income from any
        such investment shall be held by Escrow Agent, shall be
        reinvested in accordance with this Section 14 and shall be
        considered part of the Escrow Property.

             Section 15.  Security Interest.  To secure the obligations
        that may be owed it hereunder, Thermo shall have a security
        interest in the Escrow Property, and for purposes of protection
        of an enforceable security interest, possession of the Escrow
        Property by the Escrow Agent shall be deemed possession by
        Thermo.

             Section 16.  Notices and Communications.  Any notice or
        other communications hereunder shall be deemed to have been duly
        delivered if delivered by hand or overnight courier service to
        the party to whom such notice or other communication is to be
        delivered at such party's address set forth below, or sent by

              Section 17.  Governing Law.  This Agreement shall be
        governed by the law of the State of Delaware applicable to
        agreements made and to be performed wholly within such
        jurisdiction, without regard to the conflicts of laws provisions
        thereof.  Each of the parties agrees to personal jurisdiction in
        any action brought under this Agreement in any court, federal or
        state, within the State of Florida having subject matter
        jurisdiction over such action.  The parties to this Agreement
        agree that any suit, action or proceeding arising out of or
        relating to this Agreement may be instituted in the United States
        District Court located in Orlando, Florida, or, in the absence of
        jurisdiction, the Superior Court for Orange County, Florida.
        Each party waives any objection which such party may have now or
        hereafter to the laying of the venue of any such suit, action or
        proceeding, and irrevocably submits to the jurisdiction of any
        such court in any such suit, action or proceeding and hereby
        agrees that such party cannot contest any judgment rendered
        thereby based on lack of jurisdiction, improper venue or
        inadequate service of process.  The Shareholder Representative
        hereby agrees to remain a resident of Florida at his current
        address (or as reported in writing to Thermo), unless and until a
        successor Shareholder Representative with a Florida residence is
        appointed pursuant to documentation acceptable to Thermo.

             Section 18.  Amendments.  This instrument supersedes any and
        all prior agreements among the parties with regard to the matters

        amendment is sought.

        this Agreement shall be effective unless made in a writing signed
        by the party against whom the enforcement of the waiver is
        sought.  No waiver of any term or provision of this Agreement
        shall be deemed to be a waiver of any other breach of such term
        or provision of this Agreement.

        Agreement are for the purposes of reference only and shall not
        limit or otherwise affect any of the terms or provisions hereof.

             Section 21.  Successor and Assigns.  The rights and
        obligations of the parties hereto shall inure to the benefit of
        and shall be binding upon the successors and assigns of each of
        them; provided, however, that neither this Agreement nor any of
        the rights, interests or obligations hereunder shall be assigned
        by any of the parties hereto without the prior written consent of
        the other parties hereto.

             Section 22.  Counterparts.  This Agreement may be executed

                                                     January __, 1995

        Coleman Research Corporation
        201 South Orange Avenue, Suite 1300
        Orlando, Florida  32801

        Thermo Electron Corporation
        81 Wyman Street
        Waltham, Massachusetts  02254

        Ladies and Gentlemen:

             The undersigned Shareholder (the "Shareholder") of Coleman
        Research Corporation, a Florida corporation ("CRC"), understands
        that CRC has entered into an Agreement and Plan of Merger (the
        "Merger Agreement") dated as of January __, 1995 among Thermo
        Electron Corporation, a Delaware corporation ("Thermo"), CRC
        Acquisition Corporation, a Delaware corporation and a
        wholly-owned subsidiary of Thermo ("Acquisition"), and CRC.
        Pursuant to the Merger Agreement Acquisition will merge (the
        "Merger") with and into CRC, following which CRC will become a
        wholly-owned subsidiary of Thermo.  The Merger Agreement provides
        that, on the Effective Date of the Merger (as defined in the
        Merger Agreement), all of the outstanding shares of capital stock
        of CRC will be converted into shares of common stock of Thermo
        (the "Thermo Common Stock") in accordance with the applicable
        exchange ratio specified in the Merger Agreement.

             The Shareholder has been advised that as of the date hereof,
        the Shareholder may be deemed to be an "affiliate" of CRC, as the
        term "affiliate" is (i) defined for purposes of paragraphs (c)
        and (d) of Rule 145 promulgated by the Securities and Exchange
        Commission (the "Commission") under the Securities Act of 1933,
        as amended (the "Act"), and (ii) used in and for purposes of
        Accounting Series Releases 130 and 135, as amended, of the
        Commission.

             The Shareholder understands that the representations,
        warranties and covenants set forth herein will be relied upon by
        Thermo, Acquisition, CRC and other shareholders of CRC, and their
        respective counsel and accounting firms.

             The Shareholder represents, warrants and agrees with Thermo
        and CRC as follows:

             1.   The Shareholder is the beneficial owner of the shares
        of CRC capital stock and options to purchase CRC capital stock
PAGE
<PAGE>





        indicated on the last page hereof (the "CRC Securities"), which
        at the date hereof and at all times up until the Effective Date
        will be free and clear of any liens, clams, options, charges or
        other encumbrances not described on such page.  Except for CRC
        Securities, the Shareholder does not beneficially own any shares
        of capital stock of CRC or any other equity securities of CRC or
        any other options, warrants or other rights to acquire any equity
        securities of CRC.  The Shareholder has full power and authority
        to make, enter into and carry out the terms of this Agreement.

             2.   The Shareholder has been advised that the issuance of
        shares of Thermo Common Stock to the Shareholder (the "Thermo
        Shares") in connection with the Merger has been or will be
        registered with the Commission under the Act on a Registration
        Statement on Form S-4.  However, the Shareholder has also been
        advised that, since at the time the Merger is to be submitted for
        a vote of the shareholders of CRC the Shareholder may be deemed
        to be an affiliate of CRC and the distribution by the Shareholder
        of any Thermo Shares will not have been registered under the Act,
        the Shareholder  may not sell, transfer or otherwise dispose of
        the Thermo Shares unless (i) such sale, transfer or other
        disposition has been registered under the Act, (ii) such sale,
        transfer or other disposition is made in compliance with Rule 145
        promulgated by the Commission under the Act, or (iii) such sale,
        transfer or other disposition is otherwise exempt from
        registration under the Act.

             3.   The Shareholder shall not make any sale, transfer or
        other disposition of the Thermo Shares in violation of the Act or
        the rules and regulations promulgated thereunder.

             4.   The Shareholder understands that Thermo is under no
        obligation to register the sale, transfer or other disposition of
        the Thermo Shares, or Thermo Common Stock held on the
        Shareholder's behalf, under the Act or to take any other action
        necessary in order to make compliance with an exemption from such
        registration available.  

             5.   Notwithstanding any other provision hereof to the
        contrary, during the period commencing on the date hereof and
        ending at such time as financial results covering at least thirty
        days of combined operations of CRC and Thermo have been published
        by Thermo in the form of a quarterly earnings report, an
        effective registration statement filed with the Commission, a
        report to the Commission on Form 10-K, 10-Q or 8-K, or any other
        public filing or announcement which includes the combined results
        of operations of Thermo and CRC, the Shareholder will not sell,
        transfer or otherwise dispose of, or offer or agree to sell,
        transfer or otherwise dispose of, or in any other way reduce the
        risk of the Shareholder's ownership of or investment in, any CRC
        Securities, any shares of CRC common stock or other equity
        securities of CRC which the Shareholder purchases or acquires
        after the execution of this Agreement, the Thermo Shares or any
        securities which may be paid as a dividend or otherwise
PAGE
<PAGE>





        distributed thereon or with respect thereto or issued or
        delivered in exchange or substitution therefor (all such shares
        and other securities being referred to herein, collectively, as
        "Restricted Securities"), or any option, right or other interest
        with respect to any Restricted Securities.  Without limiting the
        foregoing, the Shareholder acknowledges that such restriction
        prohibits the acquisition of a "put" option or other hedging
        instrument with respect to Thermo common stock.  The Shareholder
        does not own, and has never owned, any Thermo Common Stock or
        securities relating thereto.

             6.   Stock transfer instructions will be given to Thermo's
        transfer agent with respect to the Thermo Shares and there will
        be placed on the certificates for the Thermo Shares, or any
        substitutions therefor, a legend stating in substance:

                  "The shares represented by this certificate were issued
                  in a transaction to which Rule 145 promulgated under
                  the Securities Act of 1933 applies.  The shares
                  represented by this certificate may only be transferred
                  in accordance with the terms of an agreement dated as
                  of January __, 1995 between the registered holder
                  hereof and Thermo Electron Corporation, a copy of which
                  agreement is on file at the principal offices of Thermo
                  Electron Corporation.

             7.   Unless the transfer by the Shareholder of the Thermo
        Shares has been registered under the Act, or is a sale made in
        compliance with Rule 145, Thermo reserves the right to put a
        legend on the certificates issued to any transferee of the
        Shareholder stating in substance:

                  "The shares represented by this certificate have not
                  been registered under the Securities Act of 1933 and
                  were acquired from a person who received such shares in
                  a transaction to which Rule 145 promulgated under the 
                  Securities Act of 1933 applies.  The shares may not be
                  sold, pledged or otherwise transferred except in
                  accordance with an exemption from the registration
                  requirements of the Securities Act of 1933."

             8.   The legends set forth in paragraphs 6 and 7 above shall
        be removed by delivery of substitute certificates without the
        applicable legend if, in the opinion of counsel to Thermo, (a)
        such legend is not required for purposes of the Act or (b) the
        sale or other disposition of the shares evidenced by the
        certificate is permitted by the provisions of Rule 145(d)).  In
        any event, such legend may be removed upon request of the
        Shareholder no later than two years after the Merger is
        consummated, unless the Shareholder is then an "affiliate" of
        Thermo within the meaning of Rule 145(d).

             9.   At every meeting of the shareholders of CRC called with
        respect to any of the following, and at every adjournment
PAGE
<PAGE>





        thereof, and on every action or approval by written consent of
        the shareholders of CRC with respect to any of the following, the
        Shareholder shall vote all his CRC Shares: (i) in favor of
        approval of the Merger Agreement and the Merger and any matter
        that could reasonably be expected to facilitate the Merger; and
        (ii) against approval of any proposal made in opposition to or
        competition with consummation of the Merger (the foregoing is
        hereinafter referred to as an "Opposing Proposal").

             10.  Except as required by law, including actions which
        Shareholder determines after consultation with legal counsel are
        required pursuant to Shareholder's fiduciary duties under
        applicable law, Shareholder will not, and will not permit any
        entity under Shareholder's control to: (i) solicit proxies or
        become a "participant" in a "solicitation" (as such terms are
        defined in Regulation 14A under the Exchange Act) with respect to
        an Opposing Proposal; (ii) initiate a shareholders' vote or
        action by consent of CRC shareholders with respect to an Opposing
        Proposal; or (ii) become a member of a "group" (as such term is
        used in Section 13(d) of the Exchange Act) with respect to any
        voting securities of CRC, in connection with an Opposing
        Proposal.

             11.  The Shareholder hereby covenants and agrees to execute
        and deliver any additional documents necessary or desirable, in
        the opinion of Thermo, to carry out the intent of this Agreement.

             12.  Miscellaneous.

                  12.1  If any term, provisions, covenant or  restriction
        of this Agreement is held by a court of competent jurisdiction to
        be invalid, void or unenforceable, all other terms, provisions,
        covenants and restrictions of this Agreement shall nevertheless
        remain in full force and effect and shall in no way be affected,
        impaired or invalidated.

                  12.2  This Agreement and all of the provisions hereof
        shall be binding upon and inure to the benefit of the parties
        hereto and their respective successors and permitted assigns,
        but, except as otherwise specifically provided herein, neither
        this Agreement nor any of the rights, interests or obligations of
        the parties hereto may be assigned by either of the parties
        without the prior written consent of the other.

                  12.3  This Agreement may not be modified, amended,
        altered or supplemented except upon the execution and delivery of
        a written agreement executed by the parties hereto.

                  12.4  The parties hereto acknowledge that Thermo will
        be irreparably harmed and that there will be no adequate remedy
        at law for a violation of any of the covenants or agreements of
        Shareholder set forth herein.  Therefore, it is agreed that, in
        addition to any other remedies that may be available to Thermo
        upon any such violation, Thermo shall have the right to enforce

        such covenants and agreements by specific performance, injunctive
        relief or by any other means available to Thermo at law or in
        equity.

                  12.5  All notices, requests, claims,, demands and other
        communications hereunder shall be in writing and sufficient if
        delivered in person, by cable, telegram or telex, or sent by mail

        of the parties in respect of the subject matter hereof, and

                            NONCOMPETITION AGREEMENT

             NONCOMPETITION AGREEMENT, dated as of February __, 1995, by
        and among Thermo Electron Corporation, a Delaware corporation
        ("Thermo"), Coleman Research Corporation, a Florida corporation
        ("CRC"), and Thomas J. Coleman ("Coleman").  

             WHEREAS, Thermo and CRC have entered into an Agreement and
        Plan of Merger dated January __, 1995 (the "Merger Agreement"),
        contemplating the acquisition by Thermo or its subsidiary of all
        of the issued and outstanding shares of capital stock of CRC; and

             WHEREAS, the execution and delivery of this Agreement is a
        condition precedent to the obligation of Thermo to consummate the
        transactions contemplated by the Merger Agreement; and

             WHEREAS, to induce Thermo to consummate the transactions
        contemplated in the Merger Agreement, Coleman is willing to agree
        to not compete with Thermo and CRC on the terms contained herein;

             NOW, THEREFORE, in consideration of these premises and other
        good and valuable consideration, the receipt and sufficiency of
        which is hereby acknowledged by all parties, the parties hereto
        hereby agree as follows:

             Section 1.   Definitions.  Capitalized terms used herein
        which are defined in the Merger Agreement but not defined herein
        shall have the same meanings herein as therein.

             Section 2.   Termination of Employment; Resignation as
        Director and Officer.  Effective as of the Closing Date,
        Coleman's employment with CRC shall terminate.  In addition, as
        of the Closing Date, Coleman shall resign as sole Director of CRC
        and as Chairman of the Board and from all offices he may hold in
        CRC.

             Section 3.  Noncompetition by Coleman.  Coleman agrees that
        for a period of three years after the Closing Date, he will not,
        either alone or as a partner, shareholder, officer, director,
        advisor, consultant or employee of, or as to, any company or any
        other organization or enterprise, directly or indirectly, engage
        in any activity in the United States relating to the development,
        marketing or sale of any product or service which competes with
        any product or service currently sold by CRC, currently under
        development by CRC, or which CRC may offer or develop in the
        future (collectively, the "CRC Services").  The CRC Services
        include, without limitation, systems integration, systems
        engineering and analytical services to government and commercial
        customers in the fields of information technology, energy and the
        environment, software engineering, launch systems, advanced radar
        and imaging and health systems, but do not include the materials

<PAGE>





        research products and services under development by Coleman
        Laboratories Ltd. in conjunction with Dr. Mohammad Katoot and MK
        Industries.  Notwithstanding the foregoing, it is not Thermo's
        intent to interfere with Coleman establishing or participating in
        a systems engineering business (the "Business") providing
        services similar to those of CRC as long as the Business does not
        compete with CRC and is not, in the sole judgment of CRC, in
        conflict with the best interests of CRC during the period of
        noncompetition set forth above.  For purposes of the preceding
        sentence, neither Coleman nor the Business will be deemed to be
        competing with CRC if:

                  (a)  neither Coleman nor the Business takes any action
             to encourage any party to place restrictions (e.g., small
             business set aside restrictions) on procurements in which
             CRC has an interest in participating and in which such
             restrictions would be, in the sole judgment of CRC, not in
             the best interests of CRC; or

                  (b)  Coleman and/or the Business participate as a prime
             contractor or as a subcontractor on any procurement in which
             CRC does not intend to participate either as a prime
             contractor or as a subcontractor; or

                  (c)  Coleman and/or the Business bid on any Small
             Business Innovative Research contracts, irrespective of
             whether CRC intends to participate in such a bid as a
             subcontractor to another eligible bidder.

             Notwithstanding the foregoing, Coleman may, solely as an
        investment, own securities of any such competing company that is
        traded on a recognized securities exchange if he does not,
        directly or indirectly, own one percent (1%) or more of any class
        of securities of any such competing company (other than Thermo).
        Without limiting the generality of the first sentence of this
        Section 3, during the period of noncompetition set forth above,
        Coleman shall not (i) divert or attempt to divert (by
        solicitation or by any other means) any customers of CRC to any
        competitor of CRC, or (ii) hire, solicit, interfere with or
        endeavor to entice away any officer or employee of CRC or in any
        matter encourage any officer or employee of CRC to leave its
        employ; except that he may solicit Harriett C. Coleman, Michael
        Coleman, Benjamin Patz and Cynthia Patz to leave the employ of
        CRC.

             If this Section 3 or any portion hereof shall be determined
        by a court of competent jurisdiction to be unenforceable by
        reason of its extending for too great a period of time or over
        too large a geographic area or over too great a range of
        activities, it shall be interpreted to extend only over the
        maximum period of time, geographic area or range of activities as
        to which it may be enforceable.

             Coleman agrees that damages are an inadequate remedy for any
        breach of this Section 3 and that Thermo shall, whether or not it
        is pursuing any potential remedies at law, be entitled to
        equitable relief in the form of preliminary and permanent
        injunctions without bond or other security in the event it claims
        any actual or threatened breach hereof. 

             Section 4.   Notices and Communications.  Any notices or
        other communications hereunder shall be deemed to have been duly
        delivered if delivered by hand or overnight courier service to
        the party to whom such notice or other communication is to be
        delivered at such parties' address set forth below, or sent by
        certified or registered mail, return receipt requested, postage

        or to such other address, or to the attention of such other
        individual, as any party hereto may designate in writing to the
        other parties to this Agreement.  Any such notice, request,
        demand, consent or other communication shall be deemed to have
        been given on the earlier of (i) the date of delivery if by hand
        or by overnight courier service, or (ii) five (5) days after
        having been mailed.

             Section 5.   Governing Law.  This Agreement shall be
        governed by the law of the State of Florida applicable to
        agreements made and to be performed wholly within such
        jurisdiction, without regard to the conflicts of laws provisions
        thereof.  Each of the parties agrees to personal jurisdiction in

        state, within the State of Florida having subject matter
        jurisdiction over such action.  The parties to this Agreement
        agree that any suit, action or proceeding arising out of or

        Each party waives any objection which such party may have now or
        hereafter to the laying of the venue of any such suit, action or
        proceeding, and irrevocably submits to the jurisdiction of any
        such court in any such suit, action or proceeding and hereby
        agrees that such party cannot contest any judgment rendered
        thereby based on lack of jurisdiction, improper venue or
        inadequate service of process.  In the event litigation is
        maintained by a party to this Agreement against any other party,
        then the prevailing party in such litigation shall be entitled to
        recover from the non-prevailing party reasonable attorneys' fees
        and costs of suit.

             Section 6.   Amendments.  This instrument supersedes any and
        all prior agreements among the parties with regard to the matters

        purchased with CRC funds will be owned by CRC and may be
        reclaimed by CRC only if this research effort is terminated or
        this agreement is breached by KATOOT. KATOOT agrees to maintain
        and secure equipment. The remaining CRC funds will be provided to
        KATOOT, to expedite development of MATERIAL(S) acceptable to CRC.
        Monthly financial and technical progress reports will be
        submitted to CRC by KATOOT.

        4.   License Grants - KATOOT hereby grants to CRC the world-wide
        exclusive rights (exclusive to all others, Including, but not
        limited to, KATOOT) to use and sell and sub-license without
        KATOOT's consent, the use of the following three general classes
        of GOVERNMENT MATERIALS: 1) laser materials (except x-ray laser
        applications), 2) electromagnetic energy absorbing materials for
        stealth applications, and 3) detector/sensor materials.
        GOVERNMENT MATERIALS are defined as all MATERIALS used for all
        U.S. and foreign military purposes and also for all other
        purposes where the ultimate use Is by or for the benefit of the
        U.S. Department of Defense or U.S. Department of Energy. CRC may
        manufacture these three classes of GOVERNMENT MATERIALS subject
        to the prior approval of the steering committee which shall not
        be unreasonably withheld.

             Also, CRC Is granted world-wide exclusive rights to any
        other MATERIALS developed by KATOOT with additional CRC funds.
        CRC will put forth Its best efforts to obtain reasonable and fair
        license and royalty fees for the use of MATERIALS. CRC guarantees
        that a minimum of $15,000 per year In earned royalty fees will be
        paid to the disbursing organization, beginning three years after
        the effective date of this agreement or the steering committee is
        satisfied with CRC's marketing efforts, otherwise CRC will lose
        the rights granted herein. When these fees are specified in CRC's
        contracts, such that they are readily identifiable, sixty-percent
        (60%) of any such direct royalty payments received by CRC will be
        retained by CRC and forty percent (40%) will be paid to the
        disbursing organization as described in paragraph 2.7) above,
        except for MATERIALS that were developed with additional CRC
        funds. Fees from these CRC-financed MATERIALS will be shared on a
        30% to disbursing organization and 70% to CRC basis. In all other
        cases where fees cannot be reasonably Identified (for Instance,
        where CRC uses MATERIALS in a CRC product and then sells this
        product) any royalties or license fees to be paid by CRC to the
        disbursing organization will be negotiated in good faith on a
        case-by-case basis. It Is generally understood that these
        negotiated fees to be paid by CRC will be forty percent (40%)
        (thirty percent when CRC-financed MATERIALS are used) of the
        'fair market fees' as best as the steering committee can
        determine.

             CRC Is also granted the right of first refusal on the use of
        all other MATERIALS, including COMMERCIAL MATERIALS. COMMERCIAL
        MATERIALS are defined as all MATERIALS that are not GOVERNMENT
PAGE
<PAGE>





        MATERIALS. No licenses are granted for the use of COMMERCIAL
        MATERIALS at this time.

        5.   License and Royalty Fees for COMMERCIAL MATERIALS - The
        license and royalty fees for COMMERCIAL MATERIALS will be set by
        the steering committee on a case-by-case basis.

        6.   Marketing - Marketing of MATERIALS will begin when mutually
        agreed on a case-by-case basis. CRC is granted the right to use,
        in Its marketing, any trademark associated with MATERIALS. It Is
        understood that only MATERIALS will be marketed and that the KA
        is not to be marketed.

        7.   Disclosure - KATOOT will document the KA in sufficient
        detail so that KATOOT's GOVERNMENT MATERIALS research work on the
        three classes of MATERIALS specified in Item 4. can be continued
        by CRC In the event that KATOOT is Incapacitated for an extended
        period of time or otherwise not performing according to this
        agreement. If such an event occurs, CRC agrees to use KA only to
        develop GOVERNMENT MATERIALS. This document shall be prepared by
        KATOOT within 30 days of the effective date of this agreement,
        sealed in a package, and held by a mutually agreed upon third
        parry, to be opened and released to CRC only if KATOOT cannot
        perform or is obviously not performing. KATOOT may decide at a
        later date to disclose KA to CRC, but In any case, the KA is not
        to be disclosed to any third party by KATOOT or CRC except by
        recommendation of the steering committee. Manufacturing processes
        for MATERIALS will be disclosed to third parties only if
        MATERIALS are patented.

             Employees or other associated persons of either KATOOT or
        CRC that work on KA related research and development projects
        shall agree in writing to a nondisclosure agreement prior to
        commencing such work, and shall be re-informed of their
        obligations should any such employee be separated from either
        KATOOT or CRC.

        8.   Best Efforts - KATOOT agrees to put forth his best efforts
        in using KA to research and develop MATERIALS that can be
        marketed to the benefit of the parties to this agreement. CRC
        also agrees to put forth its best efforts to bring these
        MATERIALS to the market.

        9.   Warranties and Representations - KATOOT warrants that KA is
        presently unencumbered by any past employment or other technical
        development obligations which KATOOT may have been subject to in
        the past, and that KATOOT Is freely able to enter into this
        agreement and possesses all right and title to KA at the outset.
        KATOOT warrants that he is unaware of any patents which will be
        infringed by KA or expected MATERIALS. KATOOT warrants that KA
        has not been published, made public, or otherwise made known to
        any third party. This agreement shall Inure to the benefit of the
        parties hereto and all rights of ownership in KA and MATERIALS
        shall vest In the parties as described herein.

             COLEMAN LABORATORIES, LTD./COLEMAN RESEARCH CORPORATION
                                    AGREEMENT

        This Agreement, made the 26th day of May, 1994, by and between
        Coleman Research Corporation (hereinafter "CRC"), a Florida
        corporation with a principal business address at 5950 Lakehurst
        Dr., Orlando, FL 32819, and COLEMAN LABORATORIES, LTD.
        (hereinafter "CL"), a Florida limited partnership having a
        principal business address at 5885 Lakehurst Drive, Orlando,
        Florida 32819.

        WHEREAS, Dr. Mohammad W. Katoot (hereinafter "Katoot") has
        developed certain expertise and unique techniques In the area of
        synthesizing and developing, through simulations and experiments,
        various new and original photonic, radar, solar cell, polymer,
        and protein materials having extraordinary properties, such
        materials being potentially useful in various government
        activities and other high technology fields (such material(s)
        hereinafter referred to as the "Material" or "Materials");

        WHEREAS, CL has obtained certain rights to Materials to be
        developed by Katoot and/or MK Industries (MKI);

        WHEREAS, CRC is desirous of obtaining exploitation rights to
        certain Materials from CL when developed by Katoot/MKI;

        WHEREAS, CL is willing to grant CRC certain exclusive
        exploitation rights to Materials when and If developed by Katoot,
        UNITEK, and/or MKI, namely, all government applications of
        photonic (herein defined) and radar Materials, and all government
        applications of all conductive polymer (herein after defined)
        Materials (all such rights hereinafter referred to as the "CRC
        Materials"), provided CRC provides certain funding (as described
        herein at 3(a)) to promote the development of the Materials.
        Photonic materials are defined as any materials (except solar
        cells) that use, modify, generate, detect, or convert photons as
        part of its application(s).  Conductive polymer materials are
        defined as polymer materials that have a bulk resistivity of less
        than or equal to one ohm-centimeter.

        NOW, THEREFORE, in consideration of the mutual covenants and
        agreements set forth hereinbelow, CL and CRC agree as follows:

        1.   Grant of License.

        CL hereby grants to CRC and CRC accepts an exclusive world-wide
        license to further develop, test, analyze, make, use, sell, and
        otherwise commercialize or exploit the government applications of
        all radar, photonic and conductive polymer materials developed by
        Katoot and/or MKI from 6 January 1992 forward. This grant is
        exclusive of all third parties, including MKI, and applies to all
PAGE
<PAGE>





        Materials specified herein developed by Katoot and/or MKI,
        regardless of the source of funding for the development of the
        Materials.

        2.   Right to Sublicense.

        The license granted to CRC in Section 1 hereof includes the right
        to grant any third party an exclusive or nonexclusive world-wide
        sublicense(s) to any or all CRC Materials.  These sublicense(s)
        shall include the exclusive rights to further develop, modify,
        manufacture, and otherwise commercialize the CRC Materials
        consistent with sound and reasonable business practices and
        judgment.

        3.   Research Funding and Royalties.

             (a)  Funding.

                  CRC agrees to provide MKI with support for research and
        development of the Materials of no less than $363,841, not
        Including rent or capital equipment, for calendar year 1994. The
        exact amount of such funding will be determined by CRC, in its
        sole discretion, based on its evaluation of progress made In the
        development of Materials by MKI. Such contribution can be in the
        form of cash, labor, equipment, supplies, or other personal
        property as determined by CRC. CRC will have the sole discretion
        whether or not to provide further funding past 1994. All funds
        received by MKI from CRC shall be devoted solely and exclusively
        to the research and development of the Materials.

             (b)  CRC shall pay CL a royalty on all sales or uses of CRC
        Materials. These royalties (except for the government
        applications of photonic and radar materials) will, in general,
        be equal to the royalties that would be paid by an independent
        third party under similar circumstances. The amount and nature of
        such royalty shall be mutually agreed upon by the parties through
        good faith negotiations at the time CRC begins its first use or
        sales of materials. For the government applications of photonic
        and radar Materials, CRC will pay thirty percent (30%) of the
        royalties that would be paid by an independent third party under
        similar circumstances.

             (c)  CRC shall pay all royalties due hereunder on a monthly
        basis, by the 16th day of the month immediately following the
        month In which the royalty is received or sales are made which
        require a payment of royalties under the terms of this agreement.

        4.   Patent Filing and Expenses.

             (a)  General.

        MKI has the responsibility for diligently pursuing the
        preparation, filing, prosecution (including appeals,
        interferences, and other ex parte and inter parte proceedings),
PAGE
<PAGE>





        of patent applications and patents on the Materials, throughout
        the world.  Decisions to patent or not to patent CRC aerials will
        be made jointly by MKI, CRC, and CL. Subject to the terms of
        Sections 4(b) and (c), MKI shall control and be responsible for
        the preparation and prosecution of all such patent applications
        and patents, and CRC agrees to assist MKI in connection
        therewith. Patent costs, fees, and maintenance will be paid by
        CRC. Should CRC choose not to pursue a patent on any CRC Material
        and should CL and/or MKI pursue the patent, CRC will pay
        one-third of the patent costs or lose the rights to the Materials
        as stated herein.

             (b)  Patent Filings; Cooperation.

        During the exclusive license term of this Agreement, CL and CRC
        shall cooperate fully in the preparation, filing, prosecution,
        and maintenance of all patent applications and patents licensed
        hereunder, Including the execution by CRC and CL and its agents
        or employees of all necessary papers and Instruments. Each party
        shall provide to the other parties prompt notice as to all
        matters which come to its attention which may affect the
        preparation, filing, prosecution, or maintenance of any such
        patent application or patents.

             (c)  Patent Filings; Licensee's Option to Proceed.

        In the event that MKI and/or CL does not proceed to file a patent
        application for any CRC Material in any country, CL shall so
        inform CRC at least one hundred eighty (180) days prior to the
        last date on which a patent application may be filed for that CRC
        Material under the relevant patent application statute or law of
        that country, and CRC may, at its sole option, proceed to make
        such filing at its own expense and in its own name, in which case
        CL agrees to assign any patent right in the CRC Material to CRC.
        If, pursuant to this Agreement, CL modifies, enhances, or
        otherwise exploits the Materials such that the modification or
        enhancement is itself patentable, CRC shall have the right to
        prosecute patents on such enhancements or modifications in its
        own name, and CL agrees to cooperate fully in the preparation,
        filing, prosecution, and maintenance of such applications and
        patents issued thereunder, including the execution by CL and its
        employees or agents of all necessary papers and instruments.  Any
        decision not to patent any CRC material will be made jointly by
        MKI, CRC, and CL.

        5.   Records and Reporting.

             (a)  General Bookkeeping.

                  CRC shall keep, and shall require their affiliates and
        sublicensees to keep, accurate and correct records of Materials
        sold and of all sublicenses granted under this Agreement, and all
        other records appropriate to determine the amount of royalties
        and other consideration due hereunder.  Such records shall be
PAGE
<PAGE>





        retained for at least three (3) years following a given reporting
        period.  They shall be available during normal business hours and
        at times convenient to CL for inspection in confidence at the
        expense of the Inspecting party by an independent Certified
        Public Accountant or any similarly qualified Independent person
        selected by the inspecting party and approved by CRC, which
        approval shall not be unreasonably withheld.  Information
        disclosed by CRC under this section shall be maintained in
        confidence by the inspecting party except to the extent required
        by law or regulation.

             (b)  Reporting.

                  CRC shall submit to CL within thirty (30) days after
        each calendar quarter a report setting forth for the preceding
        three (3) month period the sublicenses granted and the amount of
        Materials sold by the reporting party, Its affiliates, and
        sublicensees in each country, and the amount of royalty or other
        consideration due. If no royalties or other consideration are due
        to the other party for any reporting period, the written report
        shall so state. All such reports shall be maintained in
        confidence by the parties, except as required by law or by
        regulation.

        6.   Infringement.

             (a)  Right to Bring Suits; Adjustments.

                  If at any time a third party shall infringe or appear
        to infringe a patent on CRC Materials issued to Katoot, MKI or CL
        in any country, and MKI does not bring suit within ninety (90)
        days of learning of such infringement or apparent infringement,
        (a) CL may bring suit at CL's expense against such infringer, (b)
        if CL does not bring suit within ninety (90) days of learning of
        such infringement or apparent infringement, CRC may bring suit at
        CRC's expense against such infringer in the name of CRC or in the
        name of CL or jointly in the name of CRC and CL if CL is a
        legally indispensable party.  The party bringing the suit shall
        control the prosecution thereof, the other party being entitled
        to be represented in such suit by counsel of its own selection at
        its own expense. Any recoveries received shall first be applied
        to reimburse the litigation costs of the party hereto bringing
        the suit, and the balance, if any, shall be shared by the parties
        equally.

             (b)  Suits Required in Owner's Name; Assignment.

                  If, in exercising its rights under Section 6(a) CRC
        decides to sue, and the laws of the jurisdiction or country in
        which such suit must be brought require that only the owner of a
        patent has standing to bring such a suit such that MKI and/or
        Katoot is a legally Indispensable party, CL agrees to require
        (under separate agreement) MKI and/or Katoot to assign to CRC all
        of its right, title, and interest in the patent or patents
PAGE
<PAGE>





        concerned, subject to all government or third party rights
        therein, in which event suit by CRC on such patent or patents
        shall thereafter be brought or continued solely in its name. All
        other procedures set forth in Section 6(a) shall apply. At the
        conclusion of any legal action in which a court or other
        authority has issued a final order from which no appeal may be
        taken, CRC shall assign back to MKI, CL, and/or Katoot all of the
        right, title, and interest in the patents assigned to CRC under
        this section.

             (c)  Defense of Suits and Forced Licenses; Payment of Costs
        and Royalties.

                  If CRC employees or affiliates are sued for
        infringement of a third party's patent or for violation by CL,
        MKI (or any of its employees) or Katoot of any third party's
        rights under any trade secrets laws or similar laws in CL's,
        MKI's or Katoot's creation, development, enhancement, or
        modification of any Materials, or Is forced to take a license
        under any such patent based on the manufacture, sale, or use
        hereunder of any Material, the damages, settlement amounts,
        judgments, expenses and costs of such suit and/or the royalty

                       SECTIONS 607.1301 THROUGH 607.1320
                     OF THE FLORIDA BUSINESS CORPORATION ACT
                         RELATING TO DISSENTERS' RIGHTS


             607.1301     DISSENTER'S RIGHTS; DEFINITIONS.  The following
        definitions apply to ss. 607.1302 and 607.1320:

             (1)  "Corporation" means the issuer of the shares held by a
        dissenting shareholder before the corporate action or the
        surviving or acquiring corporation by merger or share exchange of
        that issuer.

             (2)  "Fair value," with respect to a dissenter's shares,
        means the value of the shares as of the close of business on the
        day prior to the shareholders' authorization date, excluding any
        appreciation or depreciation in anticipation of the corporate
        action unless exclusion would be inequitable.

             (3)  "Shareholders' authorization date" means the date on
        which the shareholders' vote authorizing the proposed action was
        taken, the date on which the corporation received written
        consents without a meeting from the requisite number of
        shareholders in order to authorize the action, or, in the case of
        a merger pursuant to s. 607.1104, the day prior to the date on
        which a copy of the plan of merger was mailed to each shareholder
        of record of the subsidiary corporation.

             607.1302 RIGHT OF SHAREHOLDERS TO DISSENT.  (1)  Any
        shareholder of a corporation has the right to dissent from, and
        obtain payment of the fair value of his shares in the event of,
        any of the following corporate actions:

             (a)  Consummation of a plan of merger to which the
        corporation is a party:

             1.   If the shareholder is entitled to vote on the merger,
        or

             2.   If the corporation is a subsidiary that is merged with
        its parent under s.607.1104, and the shareholders would have been
        entitled to vote on action taken, except for the applicability of
        s. 607.1104;

             (b)  Consummation of a sale or exchange of all, or
        substantially all, of the property of the corporation, other than
        in the usual and regular course of business, if the shareholder
        is entitled to vote on the sale or exchange pursuant to s.
        607.1202, including a sale in dissolution but not including a
        sale pursuant to court order or a sale for cash pursuant to a
        plan by which all or substantially all of the net proceeds of the
PAGE

        sale will be distributed to the shareholders within 1 year after
        the date of sale;

             (c)  As provided in s. 607.0902(11), the approval of a
        control-share acquisition;

             (d)  Consummation of a plan of share exchange to which the
        corporation is a party as the corporation the shares of which
        will be acquired, if the shareholder is entitled to vote on the
        plan;

             (e)  Any amendment of the articles of incorporation if the
        shareholder is entitled to vote on the amendment and if such
        amendment would adversely affect such shareholder by:

             1.   Altering or abolishing any preemptive rights attached
        to any of his shares;

             2.   Altering or abolishing the voting rights pertaining to
        any of his shares, except as such rights may be affected by the
        voting rights of new shares then being authorized of any existing
        or new class or series of shares;

             3.   Effecting an exchange, cancellation, or
        reclassification of any of his shares, when such exchange,
        cancellation, or reclassification would alter or abolish his
        voting rights or alter his percentage of equity in the
        corporation, or effecting a reduction or cancellation of accrued
        dividends or other arrearages in respect to such shares;

             4.   Reducing the stated redemption price of any of his
        redeemable shares, altering or abolishing any provision relating
        to any sinking fund for the redemption or purchase of any of his
        shares, or making any of his shares subject to redemption when
        they are not otherwise redeemable;

             5.   Making noncumulative, in whole or in part, dividends of
        any of his preferred shares which had theretofore been
        cumulative;

             6.   Reducing the stated dividend preference of any of his
        preferred shares; or

             7.   Reducing any stated preferential amount payable on any
        of his preferred shares upon voluntary or involuntary
        liquidation; or

             (f)  Any corporate action taken, to the extent the articles
        of incorporation provide that a voting or nonvoting shareholder
        is entitled to dissent and obtain payment for his shares.

             (2)  A shareholder dissenting from any amendment specified
        in paragraph (1)(e) has the right to dissent only as to those of
        his shares which are adversely affected by the amendment.
PAGE
<PAGE>






             (3)  A shareholder may dissent as to less than all the
        shares registered in his name.  In that event, his rights shall
        be determined as if the shares as to which he has dissented and
        his other shares were registered in the names of different
        shareholders.

             (4)  Unless the articles of incorporation otherwise provide,
        this section does not apply with respect to a plan of merger or
        share exchange or a proposed sale or exchange of property, to the
        holders of shares of any class or series which, on the record
        date fixed to determine the shareholders entitled to vote at the
        meeting of shareholders at which such action is to be acted upon
        or to consent to any such action without a meeting, were either
        registered on a national securities exchange or designated as a
        national market system security on an interdealer quotation
        system by the National Association of Securities Dealers, Inc.,
        or held of record by not fewer than 2,000 shareholders.

             (5)  A shareholder entitled to dissent and obtain payment
        for his shares under this section may not challenge the corporate
        action creating his entitlement unless the action is unlawful or
        fraudulent with respect to the shareholder or the corporation.

             607.1320     PROCEDURE FOR EXERCISE OF DISSENTERS' RIGHTS.
           (1) (a)  If a proposed corporate action creating dissenters'
        rights under s. 607.1320 is submitted to a vote at a
        shareholders' meeting, the meeting notice shall state that
        shareholders are or may be entitled to assert dissenters' rights
        and be accompanied by a copy of ss. 607.1301, 607.1302, and
        607.1320.  A shareholder who wishes to assert dissenter's rights
        shall:

             1.   Deliver to the corporation before the vote is taken
        written notice of his intent to demand payment for his shares if
        the proposed action is effectuated, and

             2.   Not vote his shares in favor of the proposed action.  A
        proxy or vote against the proposed action does not constitute
        such a notice of intent to demand payment.

             (b)  If proposed corporate action creating dissenters'
        rights under s. 607.1302 is effectuated by written consent
        without a meeting, the corporation shall deliver a copy of ss.
        607.1301, 607.1302, and 607.1320 to each shareholder
        simultaneously with any request for his written consent or, if
        such a request is not made, within 10 days after the date the
        corporation received written consents without a meeting from the
        requisite number of shareholders necessary to authorize the
        action.

             (2)  Within 10 days after the shareholders' authorization
        date, the corporation shall give written notice of such
        authorization or consent or adoption of the plan of merger, as
PAGE
<PAGE>





        the case may be, to each shareholder who filed a notice of intent
        to demand payment for his shares pursuant to paragraph (1)(a) or,
        in the case of action authorized by written consent, to each
        shareholder, excepting any who voted for, or consented in writing
        to, the proposed action.

             (3)  Within 20 days after the giving of notice to him, any
        shareholder who elects to dissent shall file with the corporation
        a notice of such election, stating his name and address, the
        number, classes, and series of shares as to which he dissents,
        and a demand for payment of the fair value of his shares.  Any
        shareholder failing to file such election to dissent within the
        period set forth shall be bound by the terms of the proposed
        corporate action.  Any shareholder filing an election to dissent
        shall deposit his certificates for certificated shares with the
        corporation simultaneously with the filing of the election to
        dissent.  The corporation may restrict the transfer of
        uncertificated shares from the date the shareholder's election to
        dissent is filed with the corporation.

             (4)  Upon filing a notice of election to dissent, the
        shareholder shall thereafter be entitled only to payment as
        provided in this section and shall not be entitled to vote or to
        exercise any other rights of a shareholder.  A notice of election
        may be withdrawn in writing by the shareholder at any time before
        an offer is made by the corporation, as provided in subsection
        (5), to pay for his shares.  After such offer, such notice of
        election may be withdrawn unless the corporation consents
        thereto.  However, the right of such shareholder to be paid the
        fair value of his shares shall cease, and he shall be reinstated
        to have all his rights as a shareholder as of the filing of his
        notice of election, including any intervening preemptive rights
        and the right to payment of any intervening dividend or other
        distribution or, if any such rights have expired or any such
        dividend or distribution other than in cash has been completed,
        in lieu thereof, at the election of the corporation, the fair
        value thereof in cash as determined by the board as of the time
        of such expiration or completion, but without prejudice otherwise
        to any corporate proceedings that may have been taken in the
        interim, if:

             (a)  Such demand is withdrawn as provided in this section;

             (b)  The proposed corporate action is abandoned or rescinded
        or the shareholders revoke the authority to effect such action;

             (c)  No demand or petition for the determination of fair
        value by a court has been made or filed within the time provided
        in this section; or

             (d)  A court of competent jurisdiction determines that such
        shareholder is not entitled to the relief provided by this
        section.
PAGE
<PAGE>





             (5)  Within 10 days after the expiration of the period in
        which shareholders may file their notices of election to dissent,
        or within 10 days after such corporate action is effected,
        whichever is later (but in no case later than 90 days from the
        shareholders' authorization date), the corporation shall make a
        written offer to each dissenting shareholder who has made demand
        as provided in this section to pay an amount the corporation
        estimates to be the fair value for such shares.  If the corporate
        action has not been consummated before the expiration of the
        90-day period after the shareholders' authorization date, the
        offer may be made conditional upon the consummation of such
        action.  Such notice and offer shall be accompanied by:

             (a)  A balance sheet of the corporation, the shares of which
        the dissenting shareholder holds, as of the latest available date
        and not more than 12 months prior to the making of such offer;
        and

             (b)  A profit and loss statement of such corporation for the
        12-month period ended on the date of such balance sheet or, if
        the corporation was not in existence throughout such 12-month
        period, for the portion thereof during which it was in existence.

             (6)  If within 30 days after the making of such offer any
        shareholder accepts the same, payment for his shares shall be
        made within 90 days after the making of such offer or the
        consummation of the proposed action, whichever is later.  Upon
        payment of the agreed value, the dissenting shareholder shall
        cease to have any interest in such shares.

             (7)  If the corporation fails to make such offer within the
        period specified therefor in subsection (5) or if it makes the
        offer and any dissenting shareholder or shareholders fail to
        accept the same within the period of 30 days thereafter, then the
        corporation, within 30 days after receipt of written demand from
        any dissenting shareholder given within 60 days after the date on
        which such corporate action was effected, shall, or at its
        election at any time within such period of 60 days may, file an
        action in any court of competent jurisdiction in the county in
        this state where the registered office of the corporation is
        located requesting that the fair value of such shares be
        determined.  The court shall also determine whether each
        dissenting shareholder, as to whom the corporation requests the
        court to make such determination, is entitled to receive payment
        for his shares.  If the corporation fails to institute the
        proceeding as herein provided, any dissenting shareholder may do
        so in the name of the corporation.  All dissenting shareholders
        (whether or not residents of this state), other than shareholders
        who have agreed with the corporation as to the value of their
        shares, shall be made parties to the proceeding as an action
        against their shares.  The corporation shall serve a copy of the
        initial pleading in such proceeding upon each dissenting
        shareholder who is a resident of this state in the manner
        provided by law for the service of a summons and complaint and
PAGE
<PAGE>





        upon each nonresident dissenting shareholder either by registered
        or certified mail and publication or in such other manner as is
        permitted by law.  The jurisdiction of the court is plenary and
        exclusive.  All shareholders who are proper parties to the
        proceeding are entitled to judgment against the corporation for
        the amount of the fair value of their shares.  The court may, if
        it so elects, appoint one or more persons as appraisers to
        receive evidence and recommend a decision on the question of fair
        value.  The appraisers shall have such power and authority as is
        specified in the order of their appointment or an amendment
        thereof.  The corporation shall pay each dissenting shareholder
        the amount found to be due him within 10 days after the final
        determination of the proceedings.  Upon payment of the judgment,
        the dissenting shareholder shall cease to have any interest in
        such shares.

             (8)  The judgment may, at the discretion of the court,
        include a fair rate of interest, to be determined by the court.

             (9)  The costs and expenses of any such proceeding shall be
        determined by the court and shall be assessed against the
        corporation, but all or any part of such costs and expenses may
        be apportioned and assessed as the court deems equitable against
        any or all of the dissenting shareholders who are parties to the
        proceeding, to whom the corporation has made an offer to pay for
        the shares, if the court finds that the action of such
        shareholders in failing to accept such offer was arbitrary,
        vexatious, or not in good faith.  Such expenses shall include
        reasonable compensation for, and reasonable expenses of, the
        appraisers, but shall exclude the fees and expenses of counsel
        for, and experts employed by, any party.  If the fair value of
        the shares, as determined, materially exceeds the amount which
        the corporation offered to pay therefor or if no offer was made,
        the court in its discretion may award to any shareholder who is a
        party to the proceeding such sum as the court determines to be
        reasonable compensation to any attorney or expert employed by the
        shareholder in the proceeding.

             (10) Shares acquired by a corporation pursuant to payment of
        the agreed value thereof or pursuant to payment of the judgment
        entered therefor, as provided in this section, may be held and
        disposed of by such corporation as authorized but unissued shares
        of the corporation, except that, in the case of a merger, they
        may be held and disposed of as the plan of merger otherwise
        provides.  The shares of the surviving corporation into which the
        shares of such dissenting shareholders would have been converted
        had they assented to the merger shall have the status of
        authorized but unissued shares of the surviving corporation.

                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

        Item 20.  Indemnification of Directors and Officers.

             Section 145 of the General Corporation Law of the State of
        Delaware, as amended, gives Delaware corporations the power to
        indemnify each of their present and former directors or officers
        under certain circumstances, if such person acted in good faith
        and in a  manner which he reasonably believed to be in or not
        opposed to the best interests of the corporation.

             Article Thirteenth of the Registrant's Amended and Restated
        Certificate of Incorporation provides that no director of the
        Registrant shall be liable for any breach of fiduciary duty,
        except to the extent that the Delaware General Corporation Law
        prohibits the elimination or limitation of liability of directors
        for breach of fiduciary duty.

             Article Ninth of the Registrant's Amended and Restated
        Certificate of Incorporation provides that a director or officer
        of the Registrant (a) shall be indemnified by the Registrant
        against all expenses (including attorneys' fees), judgments,
        fines and amounts paid in settlement incurred in connection with
        any litigation or other legal proceeding (other than action by or
        in the right of the Registrant) brought against him by virtue of
        his position as a director or officer of the Registrant if he
        acted in good faith and in a manner he reasonably believed to be
        in, or not opposed to, the best interests of the Registrant and
        with respect to any criminal action or proceeding, had no
        reasonable cause to believe his conduct was unlawful and (b)
        shall be indemnified by the Registrant against all expenses
        (including attorneys' fees) and amounts paid in settlement
        incurred in connection with any action by or in the right of the
        Registrant brought against him by virtue of his position as a
        director of officer of the Registrant if he acted in good faith
        and in a manner he reasonably believed to be in, or not opposed
        to, the best interests of the Registrant, except that no
        indemnification shall be made with respect to any matter as to
        which such person shall have been adjudged to be liable to the
        Registrant, unless a court determines that, despite such
        adjudication but in view of all of the circumstances, he is
        entitled to indemnification of such expenses.  Notwithstanding
        the foregoing, to the extent that a director or officer has been
        successful, on the merits or otherwise, including, without
        limitation, the dismissal of an action without prejudice, he is
        required to be indemnified by the Registrant against all expenses
        (including attorneys' fees) incurred in connection therewith.
        Expenses may be advanced to a director or officer at his request,
        provided that he undertakes to repay the amount advanced if it is
        ultimately determined that he is not entitled to indemnification
        for such expenses.  Indemnification shall be made by the
        Registrant (unless ordered by a court) only upon a determination

        that the applicable standard of conduct required for
        indemnification has been met.  Article Ninth of the Registrant's
        Amended and Restated Certificate of Incorporation further
        provides that the indemnification provided therein is not
        exclusive.  The Registrant has indemnification agreements with
        its directors and officers that provide for the maximum
        indemnification allowed by law.

             The Registrant maintains officers' and directors' insurance
        covering certain liabilities that may be incurred by officers and
        directors in the performance of their duties.

        Item 21.  Exhibits and Financial Statement Schedules.

             See the Exhibit Index included immediately preceding the
        exhibits to this Registration Statement.

        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;

                  (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;

                  (iii) To include any material information with respect 
                        to the plan of distribution not previously 
                        disclosed in the registration statement or any 
                        material change to such information in the 
                        registration statement.

             (2)  That, for the purpose of determining any liability 
                  under the Securities Act of 1933, 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.

<PAGE>






             The undersigned Registrant hereby undertakes that, for
        purposes of determining any liability under the Securities Act of
        1933, each filing of the Registrant's annual report pursuant to
        Section 13(a) or Section 15(d) of the Securities Exchange Act of
        1934 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.

             The undersigned Registrant hereby undertakes as follows:
        that prior to any public reoffering of the securities registered
        hereunder through use of a prospectus which is a part of this
        registration statement, by any person or party who is deemed to
        be an underwriter within the meaning of Rule 145(c), the issuer
        undertakes that such reoffering prospectus will contain the
        information called for by the applicable registration form with
        respect to reofferings by persons who may be deemed to be
        underwriters, in addition to the information called for by the
        other Items of the applicable form.

             The Registrant undertakes that every prospectus (i) that is
        filed pursuant to the immediately preceding undertaking or (ii)
        that purports to meet the requirements of section 10(a)(3) of the
        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
        the registration statement and will not be used until such
        amendment is effective, and that, for purposes of determining any
        liability under the Securities Act of 1933, each such
        post-effective amendment shall be deemed to be a new registration
        statement relating to the securities offered therein, and the
        offering of such securities at that time shall be deemed to be
        the initial bona fide offering thereof.

             Insofar as indemnification for liabilities arising under the
        Securities Act 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 Act and is, therefore, unenforceable.  In the
        event that a claim for indemnification against such liabilities
        (other than the payment by the Registrant of expenses incurred or
        paid by a director, officer or controlling person of the
        Registrant in the successful defense of any action, suit or
        proceeding) is asserted by such director, officer or controlling
        person in connection with the securities being registered, the
        Registrant will, unless in the opinion of its counsel the matter
        has been settled by controlling precedent, submit to a court of
        appropriate jurisdiction the question whether such
        indemnification by it is against public policy as expressed in
        the Act and will be governed by the final adjudication of such
        issue.

             The undersigned Registrant hereby undertakes to respond to
        requests for information that is incorporated by reference into
        the prospectus pursuant to Items 4, 10(b), 11, or 13 of 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.

             The undersigned Registrant hereby undertakes to supply by
        means of a post-effective amendment all information concerning a
        transaction, and the company being acquired involved therein,
        that was not the subject of and included in the registration
        statement when it became effective.
