        Compensation of Directors

        Cash Compensation  

             Directors who are not employees of the Corporation or any
        companies affiliated with Thermo Electron ("outside directors")
        receive an annual retainer of $20,000 and a fee of $1,000 per day
        for attending regular meetings of the Board of Directors or its
        committees and for each day of consulting for the Board of
        Directors, and $500 per day for participating in meetings of the
        Board of Directors or such committees held by means of conference
        telephone.  Payment of directors' fees is made quarterly. Dr. G.
        Hatsopoulos, who is a full-time employee of the Corporation, does
        not receive any cash compensation from the Corporation for his
        service as a director.  Directors are also reimbursed for
        out-of-pocket expenses and in some instances for travel time
        incurred in attending such meetings.

        Deferred Compensation Plan for Directors

             Under the Corporation's Deferred Compensation Plan for
        directors (the "Deferred Compensation Plan"), a director has the
        right to defer receipt of his cash fees until he ceases to serve
        as a director, dies or retires from his principal occupation. In
        the event of a change in control or proposed change in control of
        the Corporation that is not approved by the Board of Directors,
        deferred amounts become payable immediately. Either of the
        following is deemed to be a change of control: (a) the
        occurrence, without the prior approval of the Board of Directors,
        of the acquisition, directly or indirectly, by any person of 50%
        or more of the outstanding Common Stock; or (b) the failure of
        the persons serving on the Board of Directors immediately prior
        to any contested election of directors or any exchange offer or
        tender offer for the Common Stock to constitute a majority of the
        Board of Directors at any time within two years following any
        such event. Amounts deferred pursuant to the Deferred
        Compensation Plan are valued at the end of each quarter as units
        of Common Stock. When payable, amounts deferred may be disbursed
        solely in shares of Common Stock accumulated under the Deferred
        Compensation Plan. A total of 408,907 shares of Common Stock has
        been reserved for issuance under the Deferred Compensation Plan.

        As of March 1, 1997, deferred units equal to 304,383.44 shares of
        Common Stock were accumulated under the Deferred Compensation
        Plan.

             The Corporation's directors stock option plan (the
        "Directors Plan"), provides for the grant of stock options to
        purchase shares of common stock of the Corporation and certain of
        its majority-owned subsidiaries to outside directors as
        additional compensation for their service as directors.  Under
        the Directors Plan, outside directors are automatically granted
        options to purchase 1,000 shares of Common Stock annually.  In
        addition, the Directors Plan provides for the automatic grant of
        options to purchase up to 1,500 shares of the common stock of
        certain of the Corporation's publicly traded, majority-owned
        subsidiaries and of each majority-owned subsidiary of the
        Corporation that is subsequently "spun out" to outside investors.
        Pursuant to the Directors Plan, outside directors receive an
        annual grant of options to purchase 1,000 shares of Common Stock
        at the close of business on the date of each Annual Meeting of
        the Stockholders of the Corporation.  Options evidencing annual
        grants may be exercised at any time from and after the six-month
        anniversary of the grant date of the option and prior to the
        expiration of the option on the third anniversary of the grant
        date.  Shares acquired upon exercise of the options are subject
        to repurchase by the Corporation at the exercise price if the
        recipient ceases to serve as a director of the Corporation or any
        other Thermo Electron company prior to the first anniversary of
        the grant date.

             In addition, under the Directors Plan, outside directors are
        automatically granted options to purchase shares of common stock
        of certain of the Corporation's publicly traded, majority-owned
        subsidiaries as described in the Directors Plan and of each
        majority-owned subsidiary of the Corporation that is subsequently
        "spun out" to outside investors.  Outside directors receive
        options to purchase 1,500 shares of common stock for
        majority-owned subsidiaries that are directly owned by the
        Corporation and 1,000 shares of common stock for majority-owned
        subsidiaries that are indirectly owned by the Corporation through
        one or more of its other majority-owned subsidiaries.  The grant
        of options with respect to the common stock of subsidiaries that
        are spun out occurs on the close of business on the date of the
        first Annual Meeting of the Stockholders next following the
        subsidiary's spinout, which is the first to occur of either an
        initial public offering of the subsidiary's common stock or a
        sale of such stock to third parties in an arms-length
        transaction.  The options granted vest and become exercisable on
        the fourth anniversary of the date of grant, unless prior to such
        date the subsidiary's common stock is registered under Section 12
        of the Securities Exchange Act of 1934, as amended (''Section 12
        Registration").  In the event that the effective date of Section
        12 Registration occurs before the fourth anniversary of the grant
                                        5

        date, the option will become immediately exercisable and the
        shares acquired upon exercise will be subject to restrictions on
        transfer and the right of the Corporation to repurchase such
        shares at the exercise price in the event the director ceases to
        serve as a director of the Corporation or any other Thermo
        Electron company.  In the event of Section 12 Registration, the
        restrictions and repurchase rights shall lapse or be deemed to
        lapse at the rate of 25% per year, starting with the first
        anniversary of the grant date.  These options expire after five
        years.  At this Annual Meeting of the Stockholders, each outside
        director will be granted options to purchase 1,500 shares of
        common stock of Thermo Cardiosystems Inc. and 1,000 shares of the
        common stock of each of (i) Thermo Optek, a subsidiary of Thermo
        Instrument Systems Inc. that was spun out in June 1996, (ii)
        Thermo Fibergen Inc., a subsidiary of Thermo Fibertek Inc. that
        was spun out in September 1996, (iii) Metrika Systems
        Corporation, a subsidiary of Thermo Instrument Systems Inc. that
        was spun out in November 1996  and (iv) Thermedics Detection
        Inc., a subsidiary of Thermedics Inc. that was spun out in
        November 1996.

             The exercise price for options granted under the Directors
        Plan is the average of the closing prices of the common stock as
        reported on the New York or American Stock Exchange (or other
        principal market on which the common stock is then traded) for
        the five trading days preceding and including the date of grant,
        or, if the shares are not then traded, at the last price per
        share paid by third parties in an arms-length transaction prior
        to the option grant.  An aggregate of 450,000 shares of Common
        Stock has been reserved for issuance under the Directors Plan.

        Stock Ownership Policies for Directors

             During 1996, the Human Resources Committee of the Board of
        Directors (the "Committee") established a stock holding policy
        for directors.   The stock holding policy requires each director
        to hold a minimum of 1,000 shares of Common Stock.  Directors are
        requested to achieve this ownership level by the 1998 Annual
        meeting of Stockholders.  Directors who are also executive
        officers of the Corporation are required to comply with a
        separate stock holding policy established by the Committee in
        1996.

             In addition, the Committee adopted a policy requiring
        directors to hold shares of the Corporation's Common Stock equal
        to one-half of their net option exercises over a period of five
        years.  The net option exercise is determined by calculating the
        number of shares acquired upon exercise of a stock option, after
        deducting the number of shares that could have been traded to
        exercise the option and the number of shares that could have been
        surrendered to satisfy tax withholding obligations attributable
        to the exercise of the option.  This policy is also applicable to
        executive officers.

        (1)  In addition to grants of options to purchase Common Stock of
        the Corporation (designated in the table as TMO), the named
        executive officers have been granted options to purchase common
        stock of subsidiaries of the Corporation, either as compensation
        for their services to the Corporation or to its subsidiaries.
        Options were granted during the last three fiscal years to the
        chief executive officer and the other named executive officers in
        their capacities as executive officers of the Corporation or

        (2)  No awards of restricted stock of the Corporation were made
        to the chief executive officer or other named executive officers
        during the last three fiscal years. As of December 28, 1996, the
        amount and value of each executive officer's restricted stock
        holdings were as follows: Dr. G. Hatsopoulos - 20,250 shares
        valued at $764,438; Mr. Smith - 10,125 shares valued at $382,219.

        plan. As to Mr. Rainville, this amount represents employer
        contributions to his account under the profit sharing plan of
        Thermo Web Systems Inc., a subsidiary of Thermo Fibertek Inc. 

        (4)  Mr. John N. Hatsopoulos was appointed the president of the
        Corporation effective as of January 1, 1997.  Dr. George N.
        Hatsopoulos continues to serve as the chairman of the board and
        as chief executive officer of the Corporation.

        (5)  In addition to the matching contribution referred to in
        footnote (3), such amount includes $1,313, which represents the
        amount of compensation attributable to an interest-free loan
        provided to Mr. Rainville pursuant to the stock holding
        assistance plan of Thermo Fibertek Inc., a subsidiary of the
        Corporation.  See "Relationship with Affiliates - Stock Holding
        Assistance Plans."

        (6)  Mr. Wood did not meet the definition of "highly compensated"
        within the meaning of the Securities and Exchange Commission's
        executive compensation disclosure rules in fiscal 1994.

        were granted during fiscal 1996.

        (1)  In addition to grants of options to purchase Common Stock of
        the Corporation (designated in the table as TMO), the named
        executive officers have been granted options to purchase common
        stock of Thermedics Inc. (designated in the table as TMD), Thermo
        BioAnalysis Corporation (designated in the table as TBA), Thermo
        Fibergen Inc.. (designated in the table as TFG), ThermoLyte
        Corporation (designated in the table as TLT), Thermo Optek
        Corporation (designated in the table as TOC), ThermoQuest
        Corporation (designated in the table as TMQ), Thermo Sentron Inc.
        (designated in the table as TSR), Thermo Voltek Corp. (designated
        in the table as TVL) and Trex Medical Corporation (designated in
        the table as TXM), as part of the Corporation's stock option
        program.  All of the options reported are immediately exercisable
        as of the end of the fiscal year, except options to purchase the
        common stock of ThermoLyte Corporation, which are not exercisable
        until the earlier of (i) 90 days after the effective date of the
        registration of that company's common stock under Section 12 of
        the Securities Exchange Act of 1934 (the "Exchange Act") and (ii)
        nine years after the grant date.  In all cases, the shares
        acquired upon exercise are subject to repurchase by the granting
                                       19

        corporation at the exercise price if the optionee ceases to be
        employed by the granting corporation or another Thermo Electron
        company. The granting corporation may exercise its repurchase
        rights within six months after the termination of the optionee's
        employment. For publicly traded companies, the repurchase rights
        lapse ratably over a five- to ten-year period, depending on the
        option term, which may vary from seven to twelve years, provided
        that the optionee continues to be employed by the granting
        corporation or another Thermo Electron company.  For companies
        whose shares are not publicly traded, the repurchase rights
        generally lapse in their entirety on the ninth anniversary of the
        grant date.  Certain options granted as a part of Thermo
        Electron's stock option program have three-year terms, and the
        repurchase rights lapse in their entirety on the second
        anniversary of the grant date.  The granting corporation may
        permit the holders of such options to exercise options and to
        satisfy tax withholding obligations by surrendering shares equal
        in fair market value to the exercise price or withholding
        obligation. 

        (2)  The amounts shown on this table represent hypothetical gains
        that could be achieved for the respective options if exercised at
        the end of the option term.  These gains are based on assumed
        rates of stock appreciation of 5% and 10% compounded annually
        from the date the respective options were granted to their
        expiration date.  The gains shown are net of the option exercise
        price, but do not include deductions for taxes or other expenses
        associated with the exercise.  Actual gains, if any, on stock
        option exercises will depend on the future performance of the
        common stock of the granting corporation, the optionee's
        continued employment through the option period and the date on
        which the options are exercised.

        Stock Options Exercised During Fiscal 1996

             The following table reports certain information regarding
        stock option exercises during fiscal 1996 and outstanding stock
        options held at the end of fiscal 1996 by the Corporation's chief
        executive officer and the other named executive officers. No
        stock appreciation rights were exercised or were outstanding
        during fiscal 1996.

</TABLE>



        (1)  Options to purchase shares of the following subsidiaries of
        the Corporation have been granted to the chief executive officer
        and the other named executive officers:  Thermedics Inc.
        (designated in the table as TMD), Thermedics Detection Inc.
        (designated in the table as TDX), Thermo BioAnalysis Corporation
        (designated in the table as TBA), Thermo Cardiosystems Inc.
        (designated in the table as TCA), Thermo Ecotek Corporation
        (designated in the table as TCK), Thermo Fibergen Inc.
        (designated in the table as TFG), Thermo Fibertek Inc.
        (designated in the table as TFT), Thermo Instrument Systems Inc.
        (designated in the table as THI), ThermoLase Corporation
        (designated in the table as TLZ), ThermoLyte Corporation
        (designated in the table as TLT), Thermo Optek Corporation
        (designated in the table as TOC), Thermo Power Corporation
        (designated in the table as THP), ThermoQuest Corporation
        (designated in the table as TMQ), Thermo Remediation Inc.
        (designated in the table as THN), Thermo Sentron Inc. (designated
        in the table as TSR), ThermoSpectra Corporation (designated in
        the table as THS), Thermo TerraTech Inc. (designated in the table
        as TTT), ThermoTrex Corporation (designated in the table as TKN),
        Thermo Voltek Corporation (designated in the table as TVL) and
        Trex Medical Corporation (designated in the table as TXM).

        (2)  All of the options reported outstanding at the end of the
        fiscal year were immediately exercisable as of fiscal year-end,
        except options to purchase the common stock of ThermoLyte
        Corporation and Thermedics Detection Inc., which are not
        exercisable until the earlier of (i) 90 days after the effective
        date of the registration of the company's common stock under
        Section 12 of the Exchange Act and (ii) nine years after the
        grant date.  In all cases, the shares acquired upon exercise of
        the options are subject to repurchase by the granting corporation
        at the exercise price if the optionee ceases to be employed by
        such corporation or another Thermo Electron company. The granting
        corporation may exercise its repurchase rights within six months
        after the termination of the optionee's employment. For publicly
        traded companies, the repurchase rights generally lapse ratably
        over a five- to ten-year period, depending on the option term,
        which may vary from seven to twelve years, provided that the
        optionee continues to be employed by the granting corporation or
        another Thermo Electron company. For companies whose shares are
        not publicly traded, the repurchase rights lapse in their
        entirety on the ninth anniversary of the grant date.  Certain
        options granted as a part of Thermo Electron's stock option
        program have three-year terms, and the repurchase rights lapse in
        their entirety on the second anniversary of the grant date.  
         
        (3)  Options to purchase 135,000, 90,000 and 90,000 shares of the
                                       21
PAGE
<PAGE>





        Common Stock granted to Messrs. J. Hatsopoulos, Rainville and
        Wood, respectively, are subject to the same terms as described in
        footnote (2), except that the repurchase rights of the granting
        corporation generally do not lapse until the tenth anniversary of
        the grant date. In the event of the employee's death or
        involuntary termination prior to the tenth anniversary of the
        grant date, the repurchase rights of the granting corporation
        shall be deemed to have lapsed ratably over a five-year period
        commencing with the fifth anniversary of the grant date. 

        (4)  Options to purchase 20,000 shares of the common stock of
        Thermo Fibergen Inc. granted to Mr. Rainville are subject to the
        same terms as described in footnote (2), except that the
        repurchase rights are deemed to lapse 20% per year commencing on
        the sixth anniversary of the grant date.

        (5)  No public market for the shares underlying these options
        existed at fiscal year-end. Accordingly, no value in excess of
        exercise price has been attributed to these options. 

        Defined Benefit Retirement Plan

             Thermo Web Systems Inc., a wholly owned subsidiary of Thermo
        Fibertek Inc., maintains a defined benefit retirement plan (the
        "Retirement Plan") for eligible U.S. employees. Mr. Rainville is
        the chief executive officer of Thermo Fibertek Inc. and the only
        executive officer of the Corporation who participates in the
        Retirement Plan. The following table sets forth the estimated
        annual benefits payable under the Retirement Plan upon retirement
        to employees of the subsidiary in specified compensation and
        years-of-service classifications. The estimated benefits at
        certain compensation levels reflect the statutory limits on
        compensation that can be recognized for plan purposes. This limit
        is currently $150,000 per year.

</TABLE>

























             Each eligible employee receives a monthly retirement
        benefit, beginning at normal retirement age (65), based on a
        percentage (1.75%) of the average monthly compensation of such
        employee before retirement, multiplied by his years of service
        (up to a maximum of 30 years). Full credit is given for the first
        25 years of service, and half credit is given for years over 25
        and less than 30. Benefits are reduced for retirement before
        normal retirement age. Average monthly compensation is generally
        defined as average monthly base salary over the five years of
        highest compensation in the ten-year period preceding retirement.
        For 1995, the annual compensation of Mr. Rainville recognized for
        plan purposes was $150,000. The estimated credited years of
        service recognized under the Retirement Plan for Mr. Rainville is
        30, assuming retirement at age 65. No benefits under the
        Retirement Plan vest for an employee until after five years of
                                       22

        participation, at which time they become fully vested. The
        benefits shown in the above table are subject to reduction for
        Social Security benefits. The plan benefits shown are payable
        during the employee's lifetime unless the employee elects another
        form of benefit that provides death benefit protection.

        Severance Agreements
         
             The executive officers and certain key employees of the
        Corporation have entered into contracts with the Corporation that
        provide severance benefits if there is a change of control of the
        Corporation that is not approved by the Board of Directors and
        their employment is terminated, for whatever reason, within one
        year thereafter. For purposes of these agreements a change of
        control exists upon (i) the acquisition of 50% or more of the
        outstanding Common Stock by any person without the prior approval
        of the Board of Directors, (ii) the failure of the Board of
        Directors, within two years after any contested election of
        directors or tender or exchange offer not approved by the Board
        of Directors, to be constituted of a majority of directors
        holding office prior to such event or (iii) any other event that
        the Board of Directors determines constitutes an effective change
        of control of Thermo Electron. 
         
             In 1983, the Corporation entered into severance agreements
        with all of the named executive officers, except Mr. Rainville
        and Mr. Wood. For these severance agreements, the benefit is
        stated as an initial percentage which was established by the
        Board of Directors and was generally based upon the employee's
        age and length of service with the Corporation. Benefits are to
        be paid over a five-year period. The benefit to be paid in the
        first year is determined by applying this percentage to the
        employee's highest annual total cash remuneration in any 12-month
        period during the preceding three years. This benefit is reduced
        10% in each of the succeeding four years in which benefits are
        paid. The initial percentage to be so applied to Dr. G.
        Hatsopoulos, Mr. J. Hatsopoulos and Mr. Smith is 98.1%, 76.1% and
        59.1%, respectively. Assuming that severance benefits would have
        been payable under such agreements as of March 1, 1997, the
        payments thereunder for the first year thereof to Dr. G.
        Hatsopoulos, Mr. J. Hatsopoulos and Mr. Smith would have been
        approximately $1,074,000, $665,000 and $313,000, respectively.
        Payments under these agreements are not subject to the so-called
        "excess parachute payment" provisions under applicable provisions
        of the Internal Revenue Code of 1986, as amended. 

             During 1988, Mr. Rainville and Mr. Wood each entered into a
        severance agreement with the Corporation pursuant to which he
        will receive a lump sum benefit at the time of a qualifying
        severance equal to the highest total cash compensation paid to
        him in any twelve-month period during the three years preceding
        the severance event. A qualifying severance exists if (i) the
        officer's employment is terminated for any reason within one year
        after a change in control of the Corporation or (ii) a group of
                                       23

        directors of the Corporation consisting of directors of the
        Corporation on the date of the severance agreement or, if an
        election contest or tender or exchange offer for the
        Corporation's Common Stock has occurred, the directors of the
        Corporation immediately prior to such election contest or tender
        or exchange offer, and any future directors who are nominated or
        elected by such directors, determines that any other termination
        of the officer's employment should be treated as a qualifying
        severance. The benefits under this agreement are limited in such
        a manner that the payments will not constitute "excess parachute
        payments" under applicable provisions of the Internal Revenue
        Code of 1986, as amended.  Assuming that severance benefits would
        have been payable as of March 1, 1997, the payment under such
        agreement to Mr. Rainville and Mr. Wood would have been
        approximately $415,000 and $367,000, respectively. 

        RELATIONSHIP WITH AFFILIATES

             Thermo Electron has adopted a strategy of selling a minority
        interest in subsidiary companies to outside investors as an
        important tool in its future development.  As part of this
        strategy, Thermo Electron has created Thermedics Inc., Thermo
        Ecotek Corporation, Thermo Fibertek Inc., Thermo Instrument
        Systems Inc., Thermo Power Corporation, Thermo TerraTech Inc. and
        ThermoTrex Corporation, all of which are publicly traded,
        majority subsidiaries of the Corporation; Thermedics Inc. has
        created Thermedics Detection Inc., Thermo Cardiosystems Inc. and
        Thermo Sentron Inc. as publicly traded, majority-owned
        subsidiaries and has acquired the majority interest in a
        previously unaffiliated public company, Thermo Voltek Corp.;
        Thermo TerraTech Inc. has created Thermo Remediation Inc. as a
        publicly traded, majority-owned subsidiary; Thermo Instrument
        Systems Inc. has created Thermo BioAnalysis Corporation, Thermo
        Optek Corporation, ThermoQuest Corporation and ThermoSpectra
        Corporation as  publicly traded, majority-owned subsidiaries, and
        ThermoTrex Corporation has created ThermoLase Corporation and
        Trex Medical Corporation as publicly traded, majority-owned
        subsidiaries. From time to time, Thermo Electron and its
        subsidiaries will create other majority-owned subsidiaries as
        part of its spinout strategy. (The Corporation and such other
        majority-owned Thermo Electron subsidiaries are hereinafter
        referred to as the "Thermo Subsidiaries.") 
         
             Thermo Electron and each of the Thermo Subsidiaries
        recognize that the benefits and support that derive from their
        affiliation are essential elements of their individual
        performance. Accordingly, Thermo Electron and each of the Thermo
        Subsidiaries have adopted the Thermo Electron Corporate Charter
        (the "Charter") to define the relationships and delineate the
        nature of such cooperation among themselves. The purpose of the
        Charter is to ensure that (1) all of the companies and their
        stockholders are treated consistently and fairly, (2) the scope
        and nature of the cooperation among the companies, and each
        company's responsibilities, are adequately defined, (3) each
                                       24
PAGE
<PAGE>





        company has access to the combined resources and financial,
        managerial and technological strengths of the others, and (4)
        Thermo Electron and the Thermo Subsidiaries, in the aggregate,
        are able to obtain the most favorable terms from outside parties.
         
             To achieve these ends, the Charter identifies the general
        principles to be followed by the companies, addresses the role
        and responsibilities of the management of each company, provides
        for the sharing of group resources by the companies and provides
        for centralized administrative, banking and credit services to be
        performed by Thermo Electron. The services provided by Thermo
        Electron include collecting and managing cash generated by
        members, coordinating the access of Thermo Electron and the
        Thermo Subsidiaries (the "Thermo Group") to external financing
        sources, ensuring compliance with external financial covenants
        and internal financial policies, assisting in the formulation of
        long-range planning and providing other banking and credit
        services. Pursuant to the Charter, Thermo Electron may also
        provide guarantees of debt or other obligations of the Thermo
        Subsidiaries or may obtain external financing at the parent level
        for the benefit of the Thermo Subsidiaries. In certain instances,
        the Thermo Subsidiaries may provide credit support to, or on
        behalf of, the consolidated entity or may obtain financing
        directly from external financing sources. Under the Charter,
        Thermo Electron is responsible for determining that the Thermo
        Group remains in compliance with all covenants imposed by
        external financing sources, including covenants related to
        borrowings of Thermo Electron or other members of the Thermo
        Group, and for apportioning such constraints within the Thermo
        Group. In addition, Thermo Electron establishes certain internal
        policies and procedures applicable to members of the Thermo
        Group. The cost of the services provided by Thermo Electron to
        the Thermo Subsidiaries is covered under existing corporate
        services agreements between Thermo Electron and each of the
        Thermo Subsidiaries. 
         
             The Charter presently provides that it shall continue in
        effect so long as Thermo Electron and at least one Thermo
        Subsidiary participate. The Charter may be amended at any time by
        agreement of the participants. Any Thermo Subsidiary, including
        the Corporation, can withdraw from participation in the Charter
        upon 30 days' prior notice. In addition, Thermo Electron may
        terminate a subsidiary's participation in the Charter in the
        event the subsidiary ceases to be controlled by Thermo Electron
        or ceases to comply with the Charter or the policies and
        procedures applicable to the Thermo Group.  A withdrawal from the
        Charter automatically terminates the corporate services agreement
        and tax allocation agreement (if any) in effect between the
        withdrawing company and Thermo Electron. The withdrawal from
        participation does not terminate outstanding commitments to third
        parties made by the withdrawing company, or by Thermo Electron or
        other members of the Thermo Group, prior to the withdrawal.
        However, a withdrawing company is required to continue to comply
        with all policies and procedures applicable to the Thermo Group
                                       25

<PAGE>





        and to provide certain administrative functions mandated by
        Thermo Electron so long as the withdrawing company is controlled
        by or affiliated with Thermo Electron. 
          
             In general, under the corporate services agreements between
        Thermo Electron and each of the Thermo Subsidiaries, Thermo
        Electron's corporate staff provides each of the Thermo
        Subsidiaries with certain administrative services, including
        certain legal advice and services, risk management, employee
        benefit administration, tax advice and preparation of tax
        returns, centralized cash management and financial and other
        services. For the fiscal year ended December 28, 1996, the
        Corporation assessed each Thermo Subsidiary an annual fee equal
        to 1.0% of such subsidiary's revenues for these services.  The
        fee is reviewed annually and may be changed by mutual agreement
        of any Thermo Subsidiary and Thermo Electron. For items such as
        employee benefit plans, insurance coverage and other identifiable
        costs, Thermo Electron charges each of the Thermo Subsidiaries
        based on charges attributable to the respective subsidiary. Each
        corporate services agreement automatically renews for successive
        one-year terms, unless canceled by the subsidiary upon 30 days'
        prior notice. In addition, each corporate services agreement
        terminates automatically in the event the subsidiary ceases to be
        a member of the Thermo Group or ceases to be a participant in the
        Charter. In the event of a termination of a corporate services
        agreement, the subsidiary will be required to pay a termination
        fee equal to the fee that was paid by such subsidiary for
        services under the corporate services agreement for the
        nine-month period prior to termination. Following termination,
        Thermo Electron may provide certain administrative services on an
        as-requested basis by the subsidiary or as required in order to
        meet such subsidiary's obligations under Thermo Electron's
        policies and procedures. Thermo Electron will charge a subsidiary
        a fee equal to the market rate for comparable services if such
        services are provided to such subsidiary following termination. 
         
             Pursuant to an international distribution agreement,
        Thermedics Detection Inc. ("Thermedics Detection"), a subsidiary
        of Thermedics Inc., which is, in turn, a subsidiary of the
        Corporation, has appointed Arabian Business Machines Co. ("ABM")
        as its exclusive distributor of drug-and-explosives detection
        products in certain Middle East countries.  ABM is a member of

        Stock Holding Assistance Plans

             During 1996, the Human Resources Committee of the
        Corporation's Board of Directors (the "Committee") also
        established a stock holding policy for executive officers of the
        Corporation.  The stock holding policy specifies an appropriate
        level of ownership of the Corporation's Common Stock as a
        multiple of the officer's compensation.  For the chief executive
        officer, the multiple is one times his base salary and reference
        bonus for the calendar year.  For all other officers, the
        multiple is one times the officer's base salary.  The Committee
        deemed it appropriate to permit officers to achieve these
        ownership levels over a three-year period.

             In order to assist officers in complying with the policy,
        the Committee also adopted a stock holding assistance plan under
        which the Corporation is authorized to make interest-free loans
        to officers to enable them to purchase shares of the Common Stock
        in the open market.  The loans are required to be repaid upon the
        earlier of demand or five years from the date of the loan, unless
        otherwise authorized by the Committee.  No such loans are
        currently outstanding under this plan.

             Each of the Corporation's publicly traded, majority-owned
        subsidiaries have adopted similar stock holding policies and
        stock holding assistance plans, which are applicable to their
        executive officers.  Certain executive officers of the
        Corporation are the chief executive officers of these
        subsidiaries and are required to comply with the subsidiary's
        stock holding policies.  Mr. Arvin H. Smith, an executive vice
        president of the Corporation, is also the chief executive officer
        of Thermo Instrument Systems Inc.   Mr. William A. Rainville, a
        senior vice president of the Corporation, is also the chief
        executive officer of Thermo Fibertek Inc.   Mr. John W. Wood,
        Jr., a senior vice president of the Corporation, is also the
        chief executive officer of Thermedics Inc.  In 1996, Mr.

        Inc.  Mr. Rainville's loan is payable on the earlier of demand or
        five years from the date of the loan, unless otherwise authorized

        Thermo Fibertek Inc.  None of the other named executive officers
        have loans currently outstanding under any subsidiary stock
        holding assistance plan.
