The following is our agreement related to your retirement from the Company: 1. Termination of Employment: Your employment with the Company will terminate as of December 31, 1998 (the "Employment Termination Date"). You will be paid your regular salary through the Employment Termination Date. 2. 1998 Bonus: You will be entitled to receive a bonus for the 1998 calendar year in an amount to be determined on the same basis as other similarly situated Company executives, which bonus shall be payable at such time as such bonuses are normally paid. 3. Accrued Vacation/Expenses: You will be paid for any accrued but unused vacation time you had earned through the Employment Termination Date. You will not continue to earn vacation or other paid time off after the Employment Termination Date. Reconciliation of your outstanding expense account as of the Employment Termination Date shall be made with the approval of the chairman of the audit committee of the Board of Directors of the Company. Any amount outstanding on your account as of such date shall be deducted from the amount payable for your accrued vacation time. 4. Full Payment: You agree that all payments provided to you under paragraphs 1, 2 and 3 of this Agreement are in complete satisfaction of any and all compensation due to you from the Company through the Employment Termination Date. 5. Position: The Company shall nominate you for election to its Board of Directors at its 1999 Annual Meeting of Stockholders and its 2002 Annual Meeting of Stockholders. Assuming you are elected director by the Company's shareholders and subject to the Board of Directors fiduciary duties, the Company shall use its best efforts to cause you to remain Vice Chairman of the Board of Directors of the Company, a non-executive position with the Company, during the term of this Agreement. You will not be entitled to receive any cash compensation for your service as a director of the Company or any subsidiary thereof. 6. Employee Benefit Programs: Your participation in all employee benefit programs of the Company shall cease as of the Employment Termination Date in accordance with the terms of those programs. The Company will use its best efforts to obtain for you during the term of this Agreement health and dental care insurance for you and your dependents with substantially the same coverage as currently in effect, at the Company's sole cost and expense. You will also have the option, at your sole expense, of converting your basic life insurance coverage to an individual plan through Prudential. If interested, please let us know within 15 days following the Employment Termination Date and conversion information will be furnished to you. A conversion option is not available for long term disability coverage. 7. Money Match Plus Plan: Your active participation in the Money Match Plus Plan shall end on the Employment Termination Date. Information will be provided to you regarding various election options available to you regarding your account. 8. Stock Options: So long as you remain a director of one or more Thermo Electron companies, you shall be entitled to retain your stock options in the Company and any of its subsidiaries, subject to the terms and conditions of such options. 9. Taxes: All payments by the Company under this Agreement will be reduced by all taxes and other amounts that the Company is required to withhold under applicable law and all other deductions authorized by you. 10. Consulting Services: You agree to provide, and make yourself available to provide, consulting services to the Company on a half-time basis, at such time or times as is mutually agreeable by the parties. The term of this consulting arrangement shall commence on the day immediately following the Employment Termination Date and terminate on the fifth anniversary of the Employment Termination Date. The Company shall provide you with an office, which will be equipped with one fully-operational quotron machine for your use. The Company will also provide you with the support services of one full-time secretary. You agree to use your best efforts, business judgment and skill in rendering consulting services hereunder. This Agreement shall not prohibit you from serving on the board of directors of LOIS/USA Inc. and Premier, Inc. or from engaging in any other business activities during the consulting period provided that such other business activities (i) shall be subject to the prior approval of the Company, which approval shall not be unreasonably withheld, and provided such approval or disapproval shall be communicated to you in writing within 10 business days of such request for approval (it being understood that the failure by the Company to so communicate its disapproval in writing within such 10-day period shall be deemed an approval of such request), and (ii) do not prevent you from performing your obligations under this consulting arrangement. It is expressly agreed that you are acting as an independent contractor in performing your services hereunder and not as an employee or agent of the Company and as such will not be treated as an employee for any reason whatsoever, including but not limited to federal or state tax purposes. In the event of your death, disability or other incapacity resulting in your inability to perform your consulting duties hereunder, all compensation due and owing under this Section 10 shall continue to be payable to you or your estate. The Company may terminate your consulting arrangement for Cause and, in such event, the Company shall have no further obligation to you under this consulting arrangement. "Cause" shall mean your (a) conviction of a felony, or a misdemeanor involving material fraud or material dishonesty, (b) material fraud or material dishonesty in the course of consulting hereunder, (c) gross misconduct that is injurious to the Company or its subsidiaries and affiliates, or (d) gross neglect of your duties and responsibilities under the terms of this consulting arrangement. 11.

Company Property: You will return to the Company any and all documents, materials and information related to the Company, or its subsidiaries, affiliates or businesses, and all other property of the Company, including, without limitation, files and personal computers in your possession or control, on or before the Employment Termination Date. You may, however, retain your Company credit cards. Further, the Company agrees to transfer to you title to your Company leased vehicle for $100 and the difference between the current market value of such vehicle and such purchase price will be deemed to be additional wages and as such will be reported as wages on your W-2 statement. 13. Restriction on Purchase or Sale of Common Stock: You understand that you will continue to be a "Reporting Person" for purposes of Section 16 of the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder, and you will remain subject to insider trading regulations under the federal securities laws, for as long as you remain a director of the Company and/or any of its subsidiaries and for a period of six months following the termination of all such positions and that you are requested to preclear transactions in the Company and its subsidiaries' securities with the Company's Stock Transaction Coordinator, Ms. Pauline I.

Non-Disparagement: You agree that you will continue to support and promote the interests of the Company and its subsidiaries and affiliates and that you will not disparage the Company or its subsidiaries or affiliates, or any of the people or organizations connected with them, or do or say anything that could disrupt the good morale of the employees of the Company or otherwise harm the interests or reputation of the Company and its subsidiaries and affiliates and any of the organizations or people connected with them. The Company agrees that it will cause the officers of the Company and its subsidiaries not to disparage you or otherwise do or say anything that harms your reputation and that the Company shall be solely responsible for any breach of the provisions contained in this Section 16 by any such officers. Should any party violate the requirements of this provision, any non-breaching party shall be relieved of the requirements of this provision to the extent necessary to respond to statements made by the breaching party. Nothing in this provision shall prevent the parties from (i) complying with compulsory legal process or otherwise making disclosures in connection with litigation or administrative proceedings, (ii) making such disclosures as are necessary to obtain legal advice, (iii) making disclosures as are required by federal, state or local regulatory authorities, and (iv) making disclosures which by law are required or cannot be prohibited. 17.
