This Notice, the proxy and proxy statement enclosed herewith are sent to you by order of the board of directors. SANDRA L. LAMBERT Secretary PROXY STATEMENT The enclosed proxy is solicited by the board of directors of Thermo Instrument Systems Inc. (the "Corporation") for use at the 1999 Annual Meeting of the Stockholders to be held on Thursday, May 27, 1999 at 11:00 a.m. at The Westin Hotel, 70 Third Avenue, Waltham, Massachusetts, and any adjournment thereof. The mailing address of the executive office of the Corporation is 860 West Airport Freeway, Suite 301, Hurst, TX 76054. This proxy statement and the enclosed proxy were first furnished to Stockholders of the Corporation on or about April 19, 1999. VOTING PROCEDURES The board of directors intends to present to the meeting the election of six directors, constituting the entire board of directors. The representation in person or by proxy of a majority of the outstanding shares of the common stock of the Corporation, $.10 par value ("Common Stock"), entitled to vote at the meeting is necessary to provide a quorum for the transaction of business at the meeting. Shares can be voted only if the Stockholder is present in person or is represented by returning a properly signed proxy. Each Stockholder's vote is very important. Whether or not you plan to attend the meeting in person, please sign and promptly return the enclosed proxy card, which requires no postage if mailed in the United States. Votes of Stockholders of record who are present at the meeting in person or by proxy, abstentions, and broker non-votes (as defined below) are counted as present or represented at the meeting for purposes of determining whether a quorum exists. Shares represented by proxy will be voted in accordance with your instructions. You may specify your choice by marking the appropriate box on the proxy card. If your proxy card is signed and returned without specifying choices, your shares will be voted for the management nominees for directors and as the individuals named as proxy holders on the proxy deem advisable on all other matters as may properly come before the meeting. In order to be elected a director, a nominee must receive the affirmative vote of a majority of the shares of Common Stock present or represented by proxy and entitled to vote on the election. Withholding authority to vote for a nominee for director will be treated as shares present and entitled to vote and, for purposes of determining the outcome of the vote, will have the same effect as a vote against the nominee. If you hold your shares of Common Stock through a broker, bank or other nominee, generally the nominee may only vote the Common Stock that it holds for you in accordance with your instructions. However, if it has not timely received your instructions, the nominee may vote on certain matters for which it has discretionary voting authority. If a nominee cannot vote on a particular matter because it does not have discretionary voting authority, this is a "broker non-vote" on that matter. With regard to the election of directors, broker non-votes and withholdings of authority to vote will have no effect on the outcome of the vote. A Stockholder who returns a proxy may revoke it at any time before the Stockholder's shares are voted at the meeting by written notice to the Secretary of the Corporation received prior to the meeting, by executing and returning a later dated proxy or by voting by ballot at the meeting. The outstanding stock of the Corporation entitled to vote (excluding shares held in treasury by the Corporation) as of March 30, 1999 consisted of 119,321,984 shares of Common Stock. Only Stockholders of record at the close of business on March 30, 1999, are entitled to vote at the meeting. Each share is entitled to one vote. 1 PROPOSAL 1 ELECTION OF DIRECTORS Six directors are to be elected at the meeting, constituting the entire board of directors, each to hold office until his successor is elected and qualified or until his earlier resignation, death or removal.

The present members of the audit committee are Mr. Vintiadis (Chairman), and Col. Borman. The audit committee 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 Col. Borman (Chairman) and Mr. Vintiadis. The human resources committee reviews the performance of senior 3 members of management, approves 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 ten times, the audit committee met twice and the human resources committee met six times during fiscal 1998. Each director attended at least 75% of all meetings of the board of directors and committees on which he served that were held during fiscal 1998. Compensation of Directors Cash Compensation Outside directors receive an annual retainer of $8,000 and a fee of $1,000 per meeting for attending regular meetings of the board of directors and $500 per meeting 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. G. Hatsopoulos, Mr. Lewis and Mr. Smith are all employees of Thermo Electron or its subsidiaries and do not receive any cash compensation from the Corporation for their services as directors. Mr. J. Hatsopoulos, who is a consultant to Thermo Electron, does not receive any cash compensation from the Corporation for his service as a director during the term of his consulting contract that terminates December 2003. Directors are also reimbursed for out-of-pocket expenses incurred in attending such meetings. Deferred Compensation Plan 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 in 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 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 Electron 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 154,377 shares of Common Stock has been reserved for issuance under the Deferred Compensation Plan. As of January 2, 1999, deferred units equal to approximately 41,166 shares of Common Stock were accumulated under the Deferred Compensation Plan. Directors Stock Option Plan The Corporation's directors stock option plan (the "Directors Plan"), provides for the grant of stock options to purchase shares of Common Stock and common stock 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 the Common Stock annually. In addition, the Directors Plan provides for the automatic grant every five years of options to purchase 1,500 shares of the common stock of a majority-owned subsidiary of the Corporation that is "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. 4 In addition, under the Directors Plan, outside directors are automatically granted every five years options to purchase 1,500 shares of common stock of each majority-owned subsidiary of the Corporation that is "spun out" to outside investors. The grant 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, and also as of the close of business on the date of every fifth Annual Meeting of the Stockholders of the Corporation that occurs thereafter during the duration of the Directors Plan. 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 ("Section 12 Registration") of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). In the event that the effective date of Section 12 Registration occurs before the fourth anniversary of the grant date, the options 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. The exercise price for options granted under the Directors Plan is the average of the closing prices of the Common Stock or the common stock of the Corporation's majority-owned subsidiary, as the case may be, as reported on the American Stock Exchange (or other principal market on which the Common Stock or such subsidiary's common stock is then traded) for the five trading days immediately 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 January 31, 1999 options to purchase 63,120 shares of Common Stock were outstanding under the Directors Plan, options to purchase 24,321 shares had been exercised, options to purchase 3,512 shares had lapsed, and options to purchase 88,250 shares of Common Stock were reserved for future grant. Stock Ownership Policies for Directors The human resources committee of the board of directors (the "Committee") has 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 within a three-year period. The chief executive officer of the Corporation is required to comply with a separate stock holding policy established by the Committee, which is described in "Committee Report on Executive Compensation--Stock Ownership Policies." In addition, the Committee has a policy requiring directors to hold shares of 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 and is described in "Committee Report on Executive Compensation--Stock Ownership Policies." 5 STOCK OWNERSHIP The following table sets forth the beneficial ownership of Common Stock, as well as the common stock of Thermo Electron and each majority-owned subsidiary of the Corporation, as of January 31, 1999, with respect to (i) each director, (ii) each executive officer named in the summary compensation table under the heading "Executive Compensation" (the "named executive officers") and (iii) all directors and current executive officers as a group. In addition, the following table sets forth the beneficial ownership of Common Stock as of January 31, 1999, with respect to each person who was known by the Corporation to own beneficially more than 5% of the outstanding shares of Common Stock. While certain directors and executive officers of the Corporation are also directors and executive officers of Thermo Electron or its subsidiaries other than the Corporation, all such persons disclaim beneficial ownership of the shares of Common Stock owned by Thermo Electron.

In all cases, the shares acquired upon exercise are subject to repurchase by the granting company at the exercise price if the optionee ceases to be employed by, or ceases to be a director of, such company or any other Thermo Electron company. The granting company may exercise its repurchase rights within six months after the termination of the optionee's employment or the cessation of directorship, as the case may be. For publicly-traded companies, the repurchase rights generally lapse ratably over a one- to ten-year period, depending on the option term, which may vary from five to twelve years, provided that the optionee continues to be employed by or serve as a director of the granting company or another Thermo Electron company. Certain options have three-year terms and the repurchase rights lapse in their entirety on the second anniversary of the grant date. For companies whose shares are not publicly-traded, the repurchase rights lapse in their entirety on the ninth anniversary of the grant date. The granting company 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. Please see footnote (1) on page 11 for the company abbreviations used in this table. (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 company, the optionee's continued employment or service as a director through the option period and the date on which the options are exercised. (3) Since September 1996, Mr. Lewis has served as an officer of Thermo Electron, most recently as chief operating officer, measurement and detection. From time to time since September 1996, he has been, and in the future he may be, granted options to purchase common stock of Thermo Electron and its other subsidiaries for service in his capacity as an officer of Thermo Electron. These options are not reported in the table as they were granted as compensation for service to these companies in a capacity other than in his capacity as an executive officer of the Corporation. (4) These options were granted under stock option plans maintained by Thermo Electron companies other than the Corporation and, accordingly, are reported as a percentage of total options granted to employees of such companies. 14 Stock Options Exercised During Fiscal 1998 and Fiscal Year-End Option Values The following table reports certain information regarding stock option exercises during fiscal 1998 and outstanding stock options held at the end of fiscal 1998 by the named executive officers.

In all cases, the shares acquired upon exercise of the options reported in the table are subject to repurchase by the granting company at the exercise price if the optionee ceases to be employed by, or ceases to be a director of, such company or any other Thermo Electron company. The granting company may exercise its repurchase rights within six months after the termination of the optionee's employment or cessation of directorship, as the case may be. For publicly-traded companies, the repurchase rights generally lapse ratably over a one- to ten-year period, depending on the option term, which may vary from five to twelve years, provided that the optionee continues to be employed by or serve as a director of the granting company or another Thermo Electron company. Certain options have three-year terms and the repurchase rights lapse in their entirety on the second anniversary of the grant date. For companies whose shares are not publicly-traded, the repurchase rights lapse in their entirety on the ninth anniversary of the grant date. The granting company 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. Please see footnote (1) on page 11 for the company abbreviations used in this table as well as the following additional company abbreviations: Thermedics Inc (designated in the table as TMD), Thermo Fibertek Corporation (designated in the table as TFT), ThermoLase Corporation (designated in the table as TLZ), Thermo Power Corporation (designated 17 in the table as THP), Thermo TerraTech Corporation (designated in the table as TTT), ThermoTrex Corporation (designated in the table as TKN) and ThermoSpectra Corporation (designated in the table as THS). (2) Amounts shown in this column do not necessarily represent actual value realized from the sale of the shares acquired upon exercise of the option because in many cases the shares are not sold on exercise but continue to be held by the executive officer exercising the option. The amounts shown represent the difference between the option exercise price and the market price on the date of exercise, which is the amount that would have been realized if the shares had been sold immediately upon exercise. (3) Since September 1996, Mr. Lewis has served as an officer of Thermo Electron, most recently as chief operating officer, measurement and detection. From time to time since September 1996, he has been, and in the future he may be, granted options to purchase common stock of Thermo Electron and its other subsidiaries for services in his capacity as an officer of Thermo Electron. These options are not reported in the table as they were granted as compensation for service to Thermo Electron in a capacity other than in his capacity as an executive officer of the Corporation. (4) Options to purchase 62,500 shares of Common Stock granted to Mr. Lewis are subject to the same terms as described in footnote (2) above, except that the repurchase rights of the granting company 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 company shall be deemed to have lapsed ratably over a five year period commencing with the fifth anniversary of the grant date. (5) Options to purchase 100,000 shares of the common stock of Thermo Optek granted to Mr. Lewis are subject to the same terms as described in footnote (2) above, except that the repurchase rights are deemed to lapse 20% per year commencing on the sixth anniversary of the grant date. (6) Options to purchase 15,750, 45,000, 45,000 and 22,500 shares of the common stock of Thermo Electron granted to Mr. Helm, Dr. Chapman, Dr. Rosenthal and Mr. Howe, respectively, are subject to the same terms as described in footnote (2) above, except that the repurchase rights of the granting company 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 company shall be deemed to have lapsed ratably over a five- year period commencing with the fifth anniversary of the grant date. (7) Options to purchase 7,500 shares of common stock of Metrika Systems, 7,500 shares of common stock of ONIX Systems and 7,500 shares of common stock of Thermo Vision granted to Dr. Chapman and to Mr. Howe are subject to the same terms as described in footnote (2) above, except that the repurchase rights are deemed to lapse 20% per year commencing on the fifth anniversary of the grant date. Options to purchase 7,500 shares of common stock of ONIX Systems and 7,500 shares of common stock of Thermo Vision granted to Mr. Helm are subject to the same terms as described in footnote (2) above, except that the repurchase rights are deemed to lapse 20% per year commencing on the fifth anniversary of the grant date. (8) No public market existed for the shares underlying these options as of January 31, 1999. Accordingly, no value in excess of the exercise price has been attributed to these options. (9) Mr. Howe has two ThermoQuest options granted on January 10, 1996 that have a 12-year term. The repurchase rights are deemed to lapse 100% on the tenth anniversary for the first option for 40,000 shares. The repurchase rights are deemed to lapse 18% on the first and second anniversaries of the grant date and 8% annually starting the third anniversary of the grant date for the second option for 50,000 shares. Executive Retention Agreements Thermo Electron has entered into agreements with certain executive officers and key employees of Thermo Electron and its subsidiaries that provide severance benefits if there is a change in control of Thermo Electron and their employment is terminated by Thermo Electron "without cause" or by the individual for "good reason," as these terms are defined therein, within 18 months thereafter. For purposes of these agreements, a change in control exists upon (i) the acquisition by any person of 40% or more of the outstanding common stock 18 or voting securities of Thermo Electron; (ii) the failure of the Thermo Electron board of directors to include a majority of directors who are "continuing directors", which term is defined to include directors who were members of Thermo Electron's board on the date of the agreement or who subsequent to the date of the agreement were nominated or elected by a majority of directors who were "continuing directors" at the time of such nomination or election; (iii) the consummation of a merger, consolidation, reorganization, recapitalization or statutory share exchange involving Thermo Electron or the sale or other disposition of all or substantially all of the assets of Thermo Electron unless immediately after such transaction (a) all holders of Thermo Electron common stock immediately prior to such transaction own more than 60% of the outstanding voting securities of the resulting or acquiring corporation in substantially the same proportions as their ownership immediately prior to such transaction and (b) no person after the transaction owns 40% or more of the outstanding voting securities of the resulting or acquiring corporation; or (iv) approval by stockholders of a complete liquidation or dissolution of Thermo Electron. In 1998, Thermo Electron authorized an executive retention agreement with each of Mr. Earl R. Lewis, Dr. Richard W. K. Chapman, Mr. Denis A. Helm, Mr. Barry S. Howe and Dr. Robert J. Rosenthal. These agreements provide that in the event the individual's employment is terminated under the circumstances described above, the individual would be entitled to a lump sum payment equal to the sum of (a) in the case of Mr. Lewis, two times, and in the case of Messrs. Chapman, Helm, Howe and Rosenthal, one times, the individual's highest annual base salary in any 12 month period during the prior five-year period, plus (b) in the case of Mr. Lewis, two times, and in the case of Messrs. Chapman, Helm, Howe and Rosenthal, one times, the individual's highest annual bonus in any 12 month period during the prior five-year period. In addition, the individual would be provided benefits for a period of, in the case of Mr. Lewis, two years, and in the case of Messrs. Chapman, Helm, Howe and Rosenthal one year, after such termination, substantially equivalent to the benefits package the individual would have been otherwise entitled to receive if the individual was not terminated. Further, all repurchase rights of Thermo Electron and its subsidiaries shall lapse in their entirety with respect to all options that the individual holds in Thermo Electron and its subsidiaries, including the Corporation, as of the date of the change in control. Finally, the individual would be entitled to a cash payment equal to, in the case of Mr. Lewis, $20,000, and in the case of Messrs. Chapman, Helm, Howe and Rosenthal $15,000, to be used toward outplacement services. These executive retention agreements supersede and replace any and all prior severance arrangements that these individuals had with Thermo Electron. Assuming that the severance benefits would have been payable as of January 1, 1999, the lump sum salary and bonus payment under such agreement to Messrs. Lewis, Chapman, Helm, Howe and Rosenthal would have been approximately $1,140,000, $373,000, $280,000, $304,500 and $345,000, respectively. In the event that payments under these agreements are deemed to be so called "excess parachute payments" under the applicable provisions of the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), the individuals would be entitled to receive a gross-up payment equal to the amount of any excise tax payable by such individual with respect to such payment, plus the amount of all other additional taxes imposed on such individual attributable to the receipt of such gross-up payment. COMMITTEE REPORT ON EXECUTIVE COMPENSATION Compensation Philosophy Decisions on compensation for the Corporation's executive officers are made by the human resources committee of the board of directors (the "Committee"). The Committee follows guidelines established by the human resources committee of the board of directors of its parent company, Thermo Electron. The compensation policies followed by the Committee are designed to reward and motivate executives in achieving long-term value for Stockholders and other business objectives, to attract and retain dedicated, talented individuals to accomplish the Corporation's objectives, to recognize individual contributions as well as the performance of the Corporation and its subsidiaries, and to encourage stock ownership by executives through stock-based compensation and stock retention programs in order to link executive and Stockholder interests. The Committee evaluates the competitiveness of its compensation practices through the use of market surveys and competitive analyses prepared by its outside compensation consultants and by participating in annual compensation surveys, primarily "Project 777", an executive compensation survey prepared by Management 19 Compensation Services, a division of Hewitt Associates. The majority of firms represented in the Project 777 survey are included in the Standard & Poor's 500 Index but do not necessarily correspond to the companies included in the Corporation's peer group. Internal fairness of compensation within the organization is also an important element of the Committee's compensation philosophy. Compensation of executives is evaluated by comparing it to the compensation of other executives within the Thermo Electron organization who have responsibility to manage businesses of comparable size and complexity. The compensation program of the Corporation consists of annual cash compensation and long-term incentive compensation. Annual cash compensation is composed of base salary and performance-based incentive compensation, which is reviewed and determined annually. Long-term incentive compensation is in the form of stock-based compensation such as stock options and restricted stock awards. The process for determining the components of executive compensation for the executive officers is described below. Components of Executive Compensation Annual Cash Compensation Annual cash compensation consists of base salary and performance-based incentive compensation. The cash incentive compensation paid to an executive varies from year to year based on the performance of the Corporation and the executive. The Committee assesses the competitiveness of annual cash compensation by establishing for each executive position at the beginning of each fiscal year a salary and reference incentive compensation for the position that together are intended to approximate the mid-point of competitive total annual cash compensation for organizations that are of comparable size and complexity as the Corporation. Base Salary. Generally, executive salaries are adjusted gradually over time to reflect competitive salary levels or other considerations, such as geographic or regional market data, industry trends or internal fairness within the Corporation. The Committee may also adjust individual salaries to reflect the assumption of increased responsibilities. The salary increases in fiscal 1998 for the chief executive officer and the other named executive officers generally reflect this practice of gradual adjustment and moderation. Performance-based Incentive Compensation. The amount of incentive compensation actually earned by an executive from year to year varies with the performance of the Corporation and the executive. The Committee evaluates performance (1) by formulae using financial measures of profitability and contribution to Stockholder value and (2) by subjectively evaluating the executive's contribution to the achievement of the Corporation's long-term objectives. In fiscal 1998, the formulae used by the Committee measured return on net assets, return on sales, earnings improvement over a three-year period for the Corporation and, to a lesser extent, the Corporation's parent company, and three-year growth in earnings per share for the same companies. The financial measures are not financial targets that are met, not met or exceeded, but assess the financial performance relative to the financial performance of comparable companies and are designed to penalize below-average performance and reward above-average performance. The relative weighting of the financial measures and subjective evaluation varies depending on the executive's role and responsibilities within the organization. The incentive compensation awarded to the named executive officers (other than the chief executive officer, which is discussed below under the caption "1998 CEO Compensation") for fiscal 1998 was lower in each case than the incentive compensation awarded the previous year and reflected the financial performance in fiscal 1998 of the businesses of the Corporation for which the executives were responsible, as well as the Corporation as a whole. Long-term Incentive Compensation The primary goal of the Corporation and its parent company is to excel in the creation of long-term value for the Stockholders. The principal incentive tool used to achieve this goal is the periodic award to key employees of stock-based compensation in shares of Common Stock and common stock of other Thermo Electron companies. 20 The Committee and management believe that awards of stock-based compensation of both the Corporation and other companies within the Thermo Electron group of companies accomplish many objectives. The award of stock-based compensation to key employees encourages equity ownership in the Corporation, and closely aligns management's interests to the interests of all the Stockholders. The emphasis on stock-based compensation also results in management's compensation being closely linked to stock performance. In addition, because the employee's rights in the stock-based compensation vest over periods of varying durations and are subject to forfeiture if the employee leaves the Corporation prematurely, stock-based compensation is an incentive for key employees to remain with the Corporation long-term. The Committee believes stock-based compensation awards in the Corporation's majority-owned subsidiaries, and in its parent company, Thermo Electron, and the other majority-owned subsidiaries of Thermo Electron, are an important tool in providing incentives for performance within the entire organization. In determining awards, the Committee considers for each executive officer the annual value of stock-based compensation in the Corporation and other companies within the Thermo Electron organization that vest in the next year and compares the individual's total compensation using this value to competitive data. The Committee uses a modified Black-Scholes option pricing model to determine the value of an award. In addition, the Committee considers the aggregate amount of outstanding awards of stock-based compensation granted to all employees to monitor the number of outstanding awards under the Corporation's stock-based compensation programs. In determining the appropriate number of outstanding awards, the Committee considers such factors as the size of the company, its stage of development, and its growth strategy, as well as the aggregate awards and compensation practices of comparable companies. The Committee periodically awards stock-based compensation in the form of stock options and restricted stock based on its assessment of the total compensation of the executive, the actual and anticipated contributions of the executive (which includes a subjective assessment by the Committee of the executive's future potential within the organization), as well as the value of previously awarded stock-based compensation as described above. Such stock- based compensation awards were made to the named executive officers in 1998. In addition, the stock option awards made to the named executive officers in 1998 with respect to the common stock of Thermo Electron and certain majority- owned subsidiaries of the Corporation and Thermo Electron were determined by the human resources committees of the board of directors of the granting company using a similar analysis. In addition, certain options awarded in 1998 to the named executive officers with respect to the common stock of Thermo Electron were made by the Thermo Electron human resources committee under a program that awards options to certain eligible employees annually based on the number of shares of common stock of Thermo Electron held by the employee, as an incentive to buy and hold shares of Thermo Electron common stock. Stock Ownership Policies The Committee's compensation program is also designed to encourage executives to own shares of the Corporation's Common Stock. The Committee believes in encouraging executives to own and retain stock acquired through its stock-based compensation program or otherwise provides additional incentive for executive officers to follow strategies designed to maximize long-term value to Stockholders. The Committee established a stock holding policy for executive officers of the Corporation that required executive officers to own a multiple of their compensation in shares of the Corporation's Common Stock. For the chief executive officer, the multiple is one times his base salary and reference incentive compensation for the calendar year. For all other officers, the multiple was 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. The policy has been amended to apply only to the chief executive officer. In order to assist officers in complying with the policy, the Committee also adopted a stock holding assistance plan under which the Corporation was authorized to make interest-free loans to executive officers to enable them to purchase shares of Common Stock in the open market. This plan was also amended to apply only to the chief executive officer. The loans are required to be repaid upon the earlier of demand or the fifth anniversary of the date of the loan, unless otherwise determined by the Committee. No loans were outstanding under this plan in 1998. 21 The Committee also has adopted a policy requiring its executive officers to hold shares of 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 options. Similar stock holding policies and stock holding assistance plans have been adopted by each of the Corporation's publicly-traded, majority-owned subsidiaries. Certain executive officers of the Corporation who are chief executive officers of these subsidiaries are required to comply with these stock holding policies in lieu of the Corporation's stock holding policy and have outstanding loans under such subsidiaries' stock holding assistance plans. See "Relationship with Affiliates--Stock Holding Assistance Plans." Policy on Deductibility of Compensation Section 162(m) of the Internal Revenue Code limits the tax deduction available to public companies for annual compensation paid to senior executives in excess of $1 million unless the compensation qualifies as "performance based" or is otherwise exempt under Section 162(m). The Committee considers the potential effect of Section 162(m) in designing its compensation program, but reserves the right to use its independent judgment to approve nondeductible compensation, while taking into account the financial effects such action may have on the Corporation. From time to time, the Committee reexamines the Corporation's compensation practices and the effect of Section 162(m). 1998 CEO Compensation Annual cash compensation for Mr. Lewis is reviewed by both the Committee and the human resources committee of the board of directors of Thermo Electron, due to his responsibilities as both the Corporation's chief executive officer and as the chief operating officer, measurement and detection, of Thermo Electron, the Corporation's parent company. Each committee evaluates Mr. Lewis' performance and proposed compensation using the same process as that described above for the other executive officers of the Corporation. At the Thermo Electron level, Mr. Lewis was evaluated on his performance related to the Corporation, as well as other operating units of Thermo Electron for which he was responsible, weighted in accordance with the amount of time and effort devoted to each operation. The Corporation's Committee then reviews the analysis and determinations of the Thermo Electron committee and determines an appropriate allocation of Mr. Lewis's compensation to be paid by the Corporation, based on his relative responsibilities at the Corporation and Thermo Electron. In December 1997, the Committee reviewed and approved a salary increase for Mr. Lewis for fiscal 1998, which reflected his assumption of increased responsibilities within the Thermo Electron organization as a whole and his promotion to chief executive officer of the Corporation. In March 1999, the Committee conducted its review of Mr. Lewis' proposed cash incentive compensation based on fiscal 1998 performance. Mr. Lewis' performance-based incentive compensation was weighted 80% upon the financial performance of the Corporation and its parent company, Thermo Electron, using the measures described above for all executive officers under "Components of Executive Compensation--Annual Cash Compensation--Performance-based Incentive Compensation," and 20% upon a subjective evaluation of his performance. The incentive compensation paid to Mr. Lewis for fiscal 1998 was substantially lower than incentive compensation paid in the prior year and reflected the financial performance of the Corporation and Thermo Electron in fiscal 1998. The Committee concurred in the recommendations made by the Thermo Electron committee and agreed to an allocation of 80% of Mr. Lewis' annual cash compensation for 1998 to the Corporation. Awards to Mr. Lewis of stock-based compensation in Common Stock are reviewed and determined periodically by the Committee using the criteria described above under the caption "Components of Executive Compensation--Long-term Incentive Compensation." No awards of stock-based compensation in Common Stock were made to Mr. Lewis in fiscal 1998. Due to Mr. Lewis' position as a director of the Corporation's majority-owned subsidiaries and as chief executive officer of the Corporation, from time to time he may receive awards to purchase shares of the common 22 stock of such subsidiaries. These awards are determined using the same analysis as that described above under the caption "Components of Executive Compensation--Long-term Incentive Compensation." In 1998, Mr. Lewis was awarded stock options to purchase shares of the common stock of ONIX Systems under this program. Col. Frank Borman (Chairman) Mr. Polyvios C. Vintiadis COMPARATIVE PERFORMANCE GRAPH The Securities and Exchange Commission requires that the Corporation include in this proxy statement a line-graph presentation comparing cumulative, five- year shareholder returns for the Common Stock with a broad-based market index and either a nationally recognized industry standard or an index of peer companies selected by the Corporation.

The American Stock Exchange Market Value Index tracks the aggregate performance of equity securities of companies listed on the American Stock Exchange. The Common Stock is traded on the American Stock Exchange under the ticker symbol "THI." 23 RELATIONSHIP WITH AFFILIATES Thermo Electron has, from time to time, caused its subsidiaries to sell minority interests to investors, resulting in several majority-owned, private and publicly-held subsidiaries. Thermo Electron has created the Corporation as a majority-owned, publicly-held subsidiary. 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, including the Corporation, 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 the Thermo Subsidiaries. The Charter currently 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. 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, employee benefit administration, tax advice and preparation of tax returns, centralized cash management and financial and other services to the Corporation. The Corporation was assessed an annual fee equal to 0.8% of the Corporation's 24 revenues for these services in fiscal 1998. The annual fee will remain at 0.8% of the Corporation's revenues for fiscal 1999. The fee is reviewed annually and may be changed by mutual agreement of the Corporation and Thermo Electron. During fiscal 1998, Thermo Electron assessed the Corporation $13,300,000 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. In fiscal 1998, the Corporation was billed an additional $178,000 by Thermo Electron for certain administrative services required by the Corporation that were not covered by the Services Agreement. 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. The Corporation has entered into a Tax Allocation Agreement with Thermo Electron that outlines the terms under which the Corporation will be included in Thermo Electron's consolidated Federal and state income tax returns. Under current law, the Corporation will be included in such tax returns so long as Thermo Electron owns at least 80% of the Corporation's outstanding Common Stock. In years in which the Corporation has taxable income, it will pay to Thermo Electron amounts comparable to the taxes the Corporation would have paid if it had filed its own separate company tax returns. If Thermo Electron's equity ownership of the Corporation were to drop below 80%, the Company would file its own tax returns. In 1998, the Corporation paid Thermo Electron $28,200,000 under the Tax Allocation Agreement. From time to time the Corporation may transact business with other companies in the Thermo Group. The Corporation purchases and sells products and/or services in the ordinary course of business to Thermo Electron and Thermo Electron's other subsidiaries. In 1998, the Corporation sold a total of $1,083,000 of products to Thermo Electron and its other subsidiaries and purchased a total of $1,826,000 of products and/or services from such companies. Thermo Optek leases office and manufacturing space to Nicolet Biomedical Inc. ("Nicolet Biomedical"), a wholly owned subsidiary of Thermo Electron, pursuant to an arrangement whereby Thermo Optek charges Nicolet Biomedical its allocated share of the occupancy expenses of Thermo Optek's principal Wisconsin facility, based on the space Nicolet Biomedical utilizes. Thermo Optek recorded operating lease income of $768,000 in 1998 from Nicolet Biomedical. This lease is effective until December 31, 2001 but may be terminated by Nicolet Biomedical upon 30 days' prior notice to Thermo Optek. As of January 2, 1999, the Corporation had outstanding $140,000,000 of indebtedness to Thermo Electron, represented by a 3 3/4% Senior Convertible Note due 2000. In connection with the 1997 acquisition of Spectronic Instruments Inc. and VG Systems Limited from the Corporation, Thermo Optek borrowed $40,000,000 from Thermo Electron pursuant to a promissory note that was paid in August 1998. This note bore interest at the 90-day Commercial Paper Composite Rate plus 25 basis points, set at the beginning of each quarter. The interest rate for this note as of the payment date was 5.73%. In March 1997, the Corporation borrowed $210,000,000 from Thermo Electron to fund its acquisition of shares of Life Sciences International plc ("Life Sciences") pursuant to the Corporation's tender offer for all of the outstanding shares of Life Sciences. This obligation was evidenced by a promissory note due March 26, 1999 bearing interest at a rate equal to the 90- day Commercial Paper Composite Rate plus 25 basis points. $105,000,000 of this note was paid off in September 1997 and the remaining outstanding balance was paid off in January 1998. 25 On November 6, 1997, Thermo Power Corporation, a majority-owned subsidiary of Thermo Electron ("Thermo Power"), acquired Peek plc In January 1998, the Corporation's ONIX Systems subsidiary acquired the Peek Measurement business from Thermo Power for approximately $19,100,000, effective November 1997. The purchase price represents the sum of (i) the net tangible book value of the Peek Measurement Business as of the date of the acquisition by Thermo Power of Peek plc in November 1997, plus (ii) the total goodwill associated with Thermo Power's acquisition of Peek plc equal to the total fiscal 1997 revenue of the Peek Measurement Business relative to the total revenues of Peek plc for such period, plus (iii) $1,000,000, which represents an estimate of the amount of tax incurred by Thermo Power as a result of the transfer of the Peek Measurement Business to ONIX Systems. In addition, ONIX Systems paid $256,000 in interest, representing interest on the purchase price from November 6, 1997 through January 29, 1998 at an interest rate equal to the 90-day Commercial Paper Composite Rate plus 25 basis points, set at the beginning of each quarter. The methodology used to determine the purchase price was approved by the boards of directors of ONIX Systems and Thermo Power. In March 1999, the Corporation borrowed $200,000,000 from Thermo Electron to partially fund its acquisition of Spectra-Physics AB ("SPAB") pursuant to the Corporation's tender offer for all of the outstanding shares of SPAB. This obligation is evidenced by a promissory note due August 27, 1999 and bears interest at a rate of 5.03% from March 3, 1999 through April 3, 1999. Thereafter the note bears interest at a rate equal to the Dealer Commercial Paper Rate for 30-day maturities as reported in the Wall Street Journal ("DCP Rate") plus 25 basis points unless the Corporation's cash equivalents invested with Thermo Electron are less than the total outstanding principal amount of the note. In that event, the portion of the outstanding principal amount of the note that is in excess of the Corporation's cash balance invested with Thermo Electron would bear interest at a rate equal to the DCP Rate plus 125 basis points and the remaining principal balance would bear interest at a rate equal to the DCP Rate plus 25 basis points. ONIX Systems leases approximately 24,000 square feet of office and manufacturing space in Winchester, England on a month-to-month basis from Thermo Power. ONIX Systems pays Thermo Power rent in an amount that is approximately equal to the pro rata share of Thermo Power's occupancy costs, including utilities and taxes, which payments in 1998 were approximately $220,000. In August 1998, Thermo Electron announced a proposed reorganization involving certain of Thermo Electron's subsidiaries, including the Corporation. As part of this reorganization, Thermo Electron announced that ThermoSpectra may be taken private. It is currently contemplated that ThermoSpectra's public shareholders would receive cash in exchange for their shares of common stock of ThermoSpectra. The completion of this transaction is subject to numerous conditions, including the establishment of the price; the approval of the board of directors of the Corporation; the negotiation and execution of a definitive purchase and sale or merger agreement; the receipt of a fairness opinion from an investment banking firm that the transaction is fair to ThermoSpectra's shareholders (other than Thermo Instrument and Thermo Electron) from a financial point of view; the approval of ThermoSpectra's independent directors who are serving on a special committee for the purpose of evaluating and negotiating the proposed transaction, as well as approval by ThermoSpectra's entire Board of Directors; and clearance by the Securities and Exchange Commission of any necessary documents regarding the proposed transaction. The Corporation, along with certain other Thermo Subsidiaries, participates in a notional pool arrangement with Barclays Bank, which includes a $71,017,000 credit facility. The Corporation has access to $45,162,000 under this credit facility. Only U.K.-based Thermo Subsidiaries participate in this arrangement. Under this arrangement the Bank notionally combines the positive and negative cash balances held by the participants to calculate the net interest yield/expense for the group. The benefit derived from this arrangement is then allocated based on balances attributable to the respective participants. Thermo Electron guarantees all of the obligations of each participant in this arrangement. As of January 2, 1999, the Corporation had a positive cash balance of approximately $26,726,000, based on an exchange rate of $1.6708/GBP 1.00. For 1998, the average annual interest rate earned on GBP deposits by participants in this credit arrangement was approximately 7.7225% and the average annual interest rate paid on overdrafts was approximately 7.485%. 26 Until mid-December 1998, the Corporation, along with certain other Thermo Subsidiaries, participated in a notional pool arrangement with ABN AMRO, which included a $29,719,000 credit facility. The Corporation had access to $10,880,000 under this credit facility. Only European-based Thermo Subsidiaries participated in this arrangement. Under this arrangement the Bank notionally combined the positive and negative cash balances held by the participants to calculate the net interest yield/expense for the group. The benefit derived from this arrangement was then allocated based on balances attributable to the respective participants. Thermo Electron guaranteed all of the obligations of each participant in this arrangement. For 1998, the average annual interest rate earned on NLG deposits by participants in this credit arrangement was approximately 5.00% and the average annual interest rate paid on overdrafts was approximately 5.00%. As of mid-December 1998, the Corporation, along with certain other Thermo Subsidiaries, has entered into a modification of the above-described arrangement with ABN AMRO. Only European-based Thermo Subsidiaries participate in this arrangement. The new arrangement with ABN AMRO consists of a zero balance arrangement, which includes a $29,719,000 credit facility. The Corporation has access to $10,880,000 under this credit facility. Funds borrowed by the Corporation under this arrangement pay interest at a rate set by Thermo Finance B.V., a wholly-owned subsidiary of Thermo Electron, at the beginning of each month, based on Netherlands market rates. Funds invested by the Corporation under the arrangement earn a rate set by Thermo Finance B.V. at the beginning of each month, based on Netherlands market rates. Such invested funds are collateralized with investments principally consisting of corporate notes, U.S. government-agency securities, commercial paper, money market funds, and other marketable securities, in the amount of at least 103% of such obligation. Thermo Electron guarantees all of the obligations of each participant in this arrangement. As of January 2, 1999, the Corporation had a positive cash balance of approximately $10,355,000 based on an exchange rate of $0.5307/NLG 1.00. As of January 2, 1999, the average annual interest rate earned on NLG deposits by participants in this credit arrangement was approximately 3.63% and the average annual interest rate paid on overdrafts was approximately 4.50%. In connection with the 1996 acquisition of Kevex Instruments and Kevex X- ray, ThermoSpectra borrowed $15,000,000 from Thermo Electron pursuant to a promissory note that was paid in August 1998. In connection with the acquisition of Park Scientific Instruments Corporation in March 1997, ThermoSpectra borrowed $10,000,000 from Thermo Electron pursuant to a promissory note that was paid in March 1999. In connection with the acquisition of NESLAB Instruments, Inc. and its related sales and service entity NESLAB Instruments Europa BV in the Netherlands, from the Corporation in July 1997, ThermoSpectra borrowed $45,000,000 from Thermo Electron, pursuant to a promissory note due July 1999. To partially finance the acquisition of Sierra Research and Technology Inc. in July 1997, ThermoSpectra borrowed $5,000,000 from Thermo Electron pursuant to a promissory note due July 1999. These notes bear interest at the 90-day Commercial Paper Composite Rate plus 25 basis points, set at the beginning of each quarter. The interest rate for the notes outstanding in 1997 was 5.76%. At January 2, 1999, the Corporation owed Thermo Electron and its other subsidiaries an aggregate of $14,199,000 for amounts due under the Services Agreement and related administrative charges, for other products and services, and for miscellaneous items, excluding loans described above and $12,500,000 due to Thermo Electron under the Tax Allocation Agreement, net of amounts owed to the Corporation by Thermo Electron and its other subsidiaries for products, services and other miscellaneous items. The largest amount of such net indebtedness owed by the Corporation to Thermo Electron and its other subsidiaries since January 4, 1998 was $22,590,000. These amounts do not bear interest and are expected to be paid in the normal course of business. Thermo Electron beneficially owned approximately 86.93% of the Common Stock as of January 31, 1999. Thermo Electron intends for the foreseeable future to maintain at least 80% ownership of the Corporation. This may require the purchase by Thermo Electron of additional shares of Common Stock from time to time as the number of outstanding shares issued by the Corporation increases. These purchases may be made either in the open market or directly from the Corporation or through conversion of convertible debentures owned by Thermo Electron. The Corporation adopted a plan for the sale of its shares to Thermo Electron at the request of Thermo 27 Electron to allow Thermo Electron to maintain 80% ownership of the Corporation. The sale of shares pursuant to such plan would be made at fair market value and would be subject to approval of a committee of the board of directors formed for that purpose. As of January 2, 1999, approximately $392,000,000 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. The repurchase agreement earns a rate based on the 90-day Commercial Paper Composite Rate plus 25 basis points, set at the beginning of each quarter. Stock Holding Assistance Plans The human resources committee of the Corporation (the "Committee") has established a stock holding policy that requires executive officers of the Corporation 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 Committee also established a stock holding assistance plan under which the Corporation may make interest-free loans to executive officers to enable them to purchase Common Stock in the open market. This policy and plan were subsequently amended to apply only to the chief executive officer of the Corporation. No such loans are currently outstanding under the plan. Each of the Corporation's publicly-traded, majority-owned subsidiaries have adopted similar stock holding policies and stock holding assistance plans, which were applicable to their executive officers prior to their amendment to make them applicable only to their chief executive officers. Certain executive officers of the Corporation are also the chief executive officers of these subsidiaries and are required to comply with the subsidiary's stock holding policies. Mr. Earl R. Lewis, the Corporation's president and chief executive officer, was also the chief executive officer of Thermo Optek until January 4, 1998. Dr. Richard W. K. Chapman, a senior vice president of the Corporation, is also the chief executive officer of ThermoQuest and was chairman of the board of Thermo BioAnalysis until June 26, 1997. Mr. Barry S. Howe, a vice president of the Corporation, was also the chief executive officer of Thermo BioAnalysis until March 11, 1998 and is currently the chief executive officer of ThermoSpectra. Mr. Rosenthal, a vice president of the Corporation, was also the chief executive officer of Thermo Optek in fiscal 1998. In 1996, Mr. Lewis received a loan in the principal amount of $194,029 under the Thermo Optek stock holding assistance plan to purchase 15,000 shares of the common stock of Thermo Optek, of which amount $155,224 is still outstanding. Dr. Chapman received loans in 1996 in the principal amounts of $210,653 and $131,176, under the stock holding assistance plans of ThermoQuest and Thermo BioAnalysis, respectively, to purchase 15,000 shares of the common stock of ThermoQuest and 10,000 shares of the common stock of Thermo BioAnalysis, of which amounts $168,523 and $131,176, respectively, are still outstanding. In 1996, Mr. Howe received loans in the principal amount of $164,375 under the stock holding assistance plan of Thermo BioAnalysis to purchase 12,000 shares of Thermo BioAnalysis, of which amount $131,500 is still outstanding. In 1998, Mr. Howe received a loan in the principal amount of $141,991.78 to purchase 15,000 shares of Thermo BioAnalysis, of which the entire amount is still outstanding. In 1997, Mr. Rosenthal received a loan in the principal amount of $229,616 under the Thermo Optek stock holding assistance plan, to purchase 15,000 shares of Thermo Optek, of which the entire amount is still outstanding. Each of these loans is repayable upon the earlier of demand or the fifth anniversary of the date of the loan, unless otherwise determined by the human resources committee of the board of directors of the applicable company. 28 APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS The board of directors has appointed Arthur Andersen LLP as independent public accountants for fiscal 1999. Arthur Andersen LLP has acted as independent public accountants for the Corporation since 1986. Representatives of that firm are expected to be present at the meeting, will have the opportunity to make a statement if they desire to do so and will be available to respond to questions. OTHER ACTION Management is not aware at this time of any other matters that will be presented for action at the meeting. Should any such matters be presented, the proxies grant power to the proxy holders to vote shares represented by the proxies in the discretion of such proxy holders. STOCKHOLDER PROPOSALS Proposals of Stockholders intended to be included in the proxy statement and form of proxy relating to the 2000 Annual Meeting of the Stockholders of the Corporation and to be presented at such meeting must be received by the Corporation for inclusion in the proxy statement and form of proxy no later than December 17, 1999. Notices of Stockholder proposals submitted outside the processes of Rule 14a-8 of the Exchange Act (relating to proposals to be presented at the meeting but not included in the Corporation's proxy statement and form of proxy), will be considered untimely, and thus the Corporation's proxy may confer discretionary voting authority on the persons named in the proxy with regard to such proposals, if received after March 5, 2000. SOLICITATION STATEMENT The cost of solicitation of proxies will be borne by the Corporation. Solicitation will be made primarily by mail, but regular employees of the Corporation may solicit proxies personally or by telephone, facsimile transmission or telegram. Brokers, nominees, custodians and fiduciaries are requested to forward solicitation materials to obtain voting instructions from beneficial owners of stock registered in their names, and the Corporation will reimburse such parties for their reasonable charges and expenses in connection therewith.
