Committees of the Board of Directors and Meetings The Board of Directors has established an Audit Committee and a Human Resources Committee, each consisting solely of outside directors. The present members of the Audit Committee are Mr. Holubow (Chairman) and Dr. Morris. The Audit Committee 2 PAGE reviews the scope of the audit with the Corporation's independent public accountants and meets with them for the purpose of reviewing the results of the audit subsequent to its completion. The present members of the Human Resources Committee are Dr. Morris (Chairman), Dr. Gyftopoulos and Mr. Holubow. The Human Resources Committee reviews the performance of senior members of management, recommends executive compensation and administers the Corporation's stock option and other stock-based compensation plans. The Corporation does not have a nominating committee of the Board of Directors. The Board of Directors met five times, the Audit Committee met twice and the Human Resources Committee met seven times during fiscal 1997. Each director attended at least 75% of all meetings of the Board of Directors and Committees on which he served held during fiscal 1997. Compensation of Directors Cash Compensation Directors who are not employees of the Corporation, of Thermo Electron or of any other company affiliated with Thermo Electron (also referred to as "outside directors") receive an annual retainer of $2,000 and a fee of $1,000 per day for attending regular meetings of the Board of Directors and $500 per day for participating in meetings of the Board of Directors held by means of conference telephone and for participating in certain meetings of committees of the Board of Directors. Payment of directors' fees is made quarterly. Dr. Appleton, Mr. Melas-Kyriazi, Mr. Powell and Mr. Rainville are all employees of Thermo Electron or its subsidiaries and do not receive any cash compensation from the Corporation for their services as directors. Directors are also reimbursed for out-of-pocket expenses 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 acquisition, without the prior approval of the Board of Directors, directly or indirectly, by any person of 50% or more of the outstanding Common Stock or the outstanding common stock of Thermo TerraTech or 25% or more of the outstanding common stock of Thermo Electron; 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 or the common stock of Thermo TerraTech or Thermo Electron to constitute a majority of the Board of Directors at any time within two years following any 3 PAGE such event. Amounts deferred pursuant to the Deferred Compensation Plan are valued at the end of each quarter as units of the Corporation's Common Stock. When payable, amounts deferred may be disbursed solely in shares of Common Stock accumulated under the Deferred Compensation Plan. A total of 37,500 shares of Common Stock have been reserved for issuance under the Deferred Compensation Plan. As of June 28, 1997, deferred units equal to 5,784 full shares of Common Stock were accumulated under the Deferred Compensation Plan. Directors Stock Option Plan The Corporation's directors stock option plan, which was amended in 1995, (the "Directors Plan") provides for the grant of stock options to purchase shares of Common Stock of the Corporation to outside directors as additional compensation for their service as directors. The Directors Plan originally provided for the grant of stock options upon a director's initial appointment. Outside directors appointed before the amendment of the plan received an option to purchase 22,500 shares of Common Stock upon their appointment or election. The amended plan provides that the size of the award to new directors is reduced by 4,500 shares each year until 1998, when the initial grant for new directors will be eliminated entirely. Accordingly, directors first appointed or elected in 1997 will receive options to purchase 13,500 shares and directors first appointed or elected in 1998 and thereafter will not receive an initial option grant. Options granted upon a director's election or appointment 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 fifth anniversary of the grant date. Such options are subject to restrictions on resale and to the repurchase by the Corporation of the shares subject to option at the exercise price if the director ceases to serve as a director of the Corporation, Thermo Electron or any subsidiary of Thermo Electron, for any reason other than death. The restriction and repurchase rights lapse in equal installments of 4,500 shares starting with the first anniversary of the grant date, provided the director has continuously served as a director of the Corporation or any other Thermo Electron company prior to that date. Commencing with the 1998 Annual Meeting of Stockholders, outside directors will receive an annual grant of options to purchase 1,000 shares of Common Stock pursuant to the Directors Plan 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 4 PAGE any other Thermo Electron company prior to the first anniversary of the grant date. 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 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. As of June 28, 1997, options to purchase 72,000 shares of Common Stock had been granted and were outstanding under the Directors Plan, no options had lapsed or been exercised, and options to purchase 78,000 shares of Common Stock were reserved and available for grant under the Directors Plan. Stock Ownership Policies for Directors During fiscal 1997, 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 fiscal 1997. 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. STOCK OWNERSHIP The following table sets forth the beneficial ownership of Common Stock, as well as the common stock of Thermo TerraTech and Thermo Electron, as of June 28, 1997, with respect to (i) each person who was known by the Corporation to own beneficially more than 5% of the outstanding shares of Common Stock, (ii) each director, (iii) each executive officer named in the summary compensation table under the heading "Executive Compensation" and (iv) all directors and current executive officers as a group. While certain directors or executive officers of the Corporation are also directors or executive officers of Thermo Electron or Thermo TerraTech, all such persons disclaim 5 PAGE beneficial ownership of the shares of Common Stock owned by Thermo TerraTech or Thermo Electron.

(TFG) and Thermo Optek Corporation (TOC). All of the options granted during the fiscal year are immediately exercisable at the date of grant. In all cases, the shares acquired upon exercise are subject to repurchase by the granting corporation at the exercise price if the optionee ceases to be employed by such corporation or any other 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 Corporation or another Thermo Electron company. The granting corporation may permit the holders of 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 applicable corporation, the optionee's continued employment through the option period and the date on which the options are exercised. (3) These options were granted under stock option plans maintained by Thermo Electron or its subsidiaries as part of Thermo Electron's compensation program and accordingly are reported as a percentage of total options granted to employees of Thermo Electron and its subsidiaries.

In all cases, the shares acquired upon exercise are subject to repurchase by the granting corporation at the exercise price if the optionee ceases to be employed by such corporation or any other 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 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. (2) Dr. Appleton has served as a vice president of Thermo Electron since 1975 and has been granted options to purchase shares of the common stock of Thermo Electron and certain of its subsidiaries other than the Corporation from time to time by Thermo Electron or such other subsidiaries. These options are not reported here as they were granted as compensation for service to Thermo Electron companies in capacities other than in his capacity as the chief executive officer of the Corporation. (3) Options to purchase 15,000 and 9,000 shares of the common stock of Thermo TerraTech held by Mr. Powell and Mr. Lousararian, respectively, are subject to the same terms described in footnote (1), except that in the event of the optionee's voluntary resignation or discharge for cause prior to February 8, 1998, all of the shares acquired upon exercise of these options are subject to repurchase by Thermo TerraTech at the exercise price. In addition, all shares acquired upon the exercise of these options are subject to restrictions on resale until February 8, 1998. (4) Options to purchase 22,500 shares of the common stock of Thermo Electron granted to Mr. Powell are subject to the same terms as described in footnote (1), 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 13 PAGE granting corporation shall be deemed to lapse ratably over a five-year period commencing with the fifth anniversary of the grant date. (5) No public market existed for the shares underlying these options as of June 28, 1997. Accordingly, no value in excess of exercise price has been attributed to these options. Severance Agreements Thermo Electron has entered into severance agreements with several key employees, including Dr. Appleton. These agreements provide severance benefits if there is a change in control of Thermo Electron that is not approved by the Board of Directors of Thermo Electron and the employee's employment with Thermo Electron or one of its majority-owned subsidiaries is terminated, for whatever reason, within one year thereafter. For purposes of the severance agreements, a change in control exists upon (i) the acquisition of 50% or more of the outstanding common stock of Thermo Electron by any person without the prior approval of the board of directors of Thermo Electron, (ii) the failure of the board of directors of Thermo Electron, 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 of Thermo Electron determines constitutes an effective change of control of Thermo Electron. The benefit under these agreements is stated as an initial percentage which was established by the Board of Directors of Thermo Electron and is generally based upon the employee's age and length of service with Thermo Electron at the time of severance. 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 remuneration in any 12-month period during the preceding three years. This benefit is reduced by 10% in each of the succeeding four years in which benefits are paid. The initial percentage to be so applied to Dr. Appleton is 40.1%. Assuming that severance benefits would have been payable under such agreements as of March 29, 1997, Dr. Appleton would have received approximately $119,906 in the first year thereof from Thermo Electron. 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 TerraTech has created the Corporation as a publicly held subsidiary, and Thermo Electron and certain of its subsidiaries have created several other privately and publicly held 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 the other 14 PAGE 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 mutual 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 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 15 PAGE 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. In addition, a withdrawing company is required to continue to comply with all policies and procedures applicable to the Thermo Group and to provide certain administrative functions mandated by Thermo Electron so long as the withdrawing company is controlled by or affiliated with Thermo Electron. As provided in the Charter, the Corporation and Thermo Electron have entered into a Corporate Services Agreement (the "Services Agreement") under which Thermo Electron's corporate staff provides certain administrative services, including certain legal advice and services, risk management, certain employee benefit administration, tax advice and preparation of tax returns, centralized cash management and certain financial and other services to the Corporation. The Corporation was assessed an annual fee equal to 1.0% of the Corporation's revenues for these services for fiscal 1997. The fee is reviewed annually and may be changed by mutual agreement of the Corporation and Thermo Electron. During fiscal 1997, Thermo Electron assessed the Corporation $1,148,000 in fees under the Services Agreement. Management believes that the charges under the Services Agreement are reasonable and that the terms of the Services Agreement are fair to the Corporation. For items such as employee benefit plans, insurance coverage and other identifiable costs, Thermo Electron charges the Corporation based on charges attributable to the Corporation. The Services Agreement automatically renews for successive one-year terms, unless canceled by the Corporation upon 30 days' prior notice. In addition, the Services Agreement terminates automatically in the event the Corporation 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 the Services Agreement, the Corporation will be required to pay a termination fee equal to the fee that was paid by the Corporation for services under the 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 Corporation or as required in order to meet the Corporation's obligations under Thermo Electron's policies and procedures. Thermo Electron will charge the Corporation a fee equal to the market rate for comparable services if such services are provided to the Corporation following termination. 16 PAGE As of March 29, 1997, $19,674,000 of the Corporation's cash equivalents were invested in a repurchase agreement with Thermo Electron. Under this agreement, the Corporation in effect lends excess cash to Thermo Electron, which Thermo Electron collateralizes with investments principally consisting of corporate notes, U.S. government agency securities, money market funds, commercial paper and other marketable securities, in the amount of at least 103% of such obligation. The Corporation's funds subject to the repurchase agreement are readily convertible into cash by the Corporation and have a maturity of three months or less. The repurchase agreement earns a rate based on the Commercial Paper Composite Rate plus 25 basis points, set at the beginning of each quarter. As of March 29, 1997, the Corporation owed Thermo TerraTech $2,650,000. Thermo TerraTech owned approximately 70.6% of the Common Stock outstanding as of June 28, 1997. Stock Holding Assistance Plan In fiscal 1997, the Corporation adopted a stock holding policy which requires its executive officers to acquire and hold a minimum number of shares of Common Stock. In order to assist the executive officers in complying with the policy, the Corporation also adopted a stock holding assistance plan under which it may make interest-free loans to certain key employees, including its executive officers, to enable such employees to purchase the Common Stock in the open market. Loans will be repaid upon the earlier of demand or the fifth anniversary of the date of the loan, unless otherwise authorized by the Human Resources Committee of the Board of Directors. No such loans were outstanding in fiscal 1997. AA972050021
