This summary and the remainder of this Offer to Purchase include information regarding the tender offer, the proposed subsequent short-form merger, Thermedics Detection Inc. and the position of Thermedics Inc. and Thermo Electron Corporation regarding the fairness of the terms of the tender offer and the merger. - - PRINCIPAL TERMS OF THE TENDER OFFER AND THE MERGER. - Tender Offer For All Outstanding Shares (pages 7 and 32). Detection Acquisition, Inc., an indirect wholly-owned subsidiary of Thermedics Inc., is offering to purchase in a tender offer all of the outstanding shares of common stock of Thermedics Detection Inc. that Thermo Electron Corporation and its subsidiaries, including Thermedics, do not currently own. - Affiliation of Thermedics Detection, Detection Acquisition, Corpak, Thermedics and Thermo Electron (page 7). Thermedics Detection is a majority-owned subsidiary of Corpak Inc., which in turn is a wholly-owned subsidiary of Thermedics. Detection Acquisition is a wholly-owned subsidiary of Corpak. Thermedics is a majority-owned subsidiary of Thermo Electron. Certain officers and directors of Thermedics and Thermo Electron are also officers or directors of Thermedics Detection. See "Certain Information Concerning The Company" and "Certain Information Concerning The Purchaser, Corpak, Thermedics And Thermo Electron." - Tender Offer Price (pages 7 and 43). The consideration being offered in the tender offer is $8.00 per share in cash. This price is equal to a premium of approximately 11.3% over the last reported sale price of Thermedics Detection common stock on the American Stock Exchange on the last trading date prior to the initial announcement, on August 12, 1998, of our intention to take Thermedics Detection private for cash or stock, and a premium of approximately 4.9% over the last reported sale price of Thermedics Detection common stock on the last trading date prior to the announcement, on December 10, 1998, of our intention to take Thermedics Detection private for cash. The last reported sale price of Thermedics Detection common stock on the American Stock Exchange on January 28, 2000, the day prior to the date that the tender offer was announced, was $7.9375 per share. The last reported sale price of Thermedics Detection common stock on the American Stock Exchange on March 8, 2000 was $7.75 per share. For more information regarding the trading range of Thermedics Detection common stock, see "Price Range Of The Shares; Dividends." - Conditions to the Tender Offer (page 37). The tender offer is subject to a number of conditions, including the condition that enough shares of Thermedics Detection common stock are tendered and not withdrawn so that on the expiration date of the tender offer Thermo Electron and its subsidiaries, including Thermedics, will together own at least 90% of Thermedics Detection's outstanding shares. Assuming that no outstanding Thermedics Detection stock options are exercised, this 90% tender condition will be met if at least 204,818 shares of Thermedics Detection common stock are validly tendered and not withdrawn prior to the expiration date of the tender offer. See "The Tender Offer--Certain Conditions Of The Offer." - Thermedics Detection Shares Outstanding; Ownership by Thermo Electron and its Subsidiaries (page 7). As of January 28, 2000, Thermedics Detection had 19,316,684 shares of common stock outstanding. In addition, options to purchase 1,009,413 shares of Thermedics Detection common stock were outstanding at such date. Thermo Electron and its subsidiaries owned in the aggregate 17,180,198 shares of Thermedics Detection common stock, or approximately 88.9% of the outstanding shares of Thermedics Detection common stock, on January 28, 2000. - Expiration of the Tender Offer (page 32). The tender offer will expire at 12:00 midnight on April 6, 2000. We can elect at any time to extend the tender offer. If we extend the tender offer, - -------------------------------------------------------------------------------- 2 3 - -------------------------------------------------------------------------------- we will issue a press release announcing the extension. See "The Tender Offer--Terms Of The Offer; Expiration Date." - Procedures for Accepting the Tender Offer and Tendering Shares (page 34). In order for your shares of Thermedics Detection common stock to be purchased in the tender offer, you must follow the procedures described in "The Tender Offer--Procedures For Accepting The Offer And Tendering Shares" and in the accompanying Letter of Transmittal prior to the expiration of the tender offer. - Payment for Tendered Shares (page 33). If all of the conditions of the tender offer are satisfied or waived and your shares of Thermedics Detection common stock are accepted for payment, we will pay you for your shares promptly after the expiration of the tender offer. See "The Tender Offer--Acceptance For Payment And Payment For Shares." - Withdrawal Rights (page 37). You may withdraw shares that you have tendered at any time on or prior to April 6, 2000, or, if the tender offer is extended, prior to the expiration of the tender offer. Unless accepted for payment on or prior to May 8, 2000, you may also withdraw shares you have tendered at any time after that date. In order for a withdrawal to be effective, American Stock Transfer & Trust Company, the depositary for the tender offer, must receive your notice of withdrawal prior to the expiration of the tender offer at one of the addresses on the back cover of this Offer to Purchase. For more information on your withdrawal rights, see "The Tender Offer--Withdrawal Rights." - Subsequent Merger (pages 27 and 52). The tender offer is the first step in Thermedics' plan to take Thermedics Detection private. If the tender offer is completed, Thermo Electron and its subsidiaries, including Thermedics, will together own at least 90% of Thermedics Detection's outstanding shares. Promptly following the closing of the tender offer, Corpak and Thermo Electron plan to contribute their shares of Thermedics Detection common stock to Detection Acquisition in exchange for common stock of Detection Acquisition. Corpak and Thermo Electron would then cause Thermedics Detection to merge with and into Detection Acquisition in a so-called "short-form" merger. In the Merger, Detection Acquisition would be the surviving corporation and would change its name to "Thermedics Detection Inc." After the merger, the surviving corporation would be owned exclusively by Thermedics, through its ownership of Corpak, and Thermo Electron. Detection Acquisition does not intend to enter into a merger agreement with Thermedics Detection or to seek the approval of the board of directors of Thermedics Detection for such merger. Stockholders of Thermedics Detection who do not tender their shares of Thermedics Detection common stock in the tender offer will not be entitled to vote their shares with respect to this merger, but will have a statutory right to demand a judicial appraisal of the fair value of their shares of Thermedics Detection common stock. See "The Merger; Appraisal Rights." The consideration in the merger would be the same $8.00 per share in cash as is payable in the tender offer. See "Special Factors--The Merger." - Other Possible Purchases of Thermedics Detection Common Stock (page 27). If, after the tender offer is completed but prior to consummation of the merger, the aggregate ownership by Thermo Electron and its subsidiaries of the outstanding shares of Thermedics Detection common stock should fall below 90% due to the exercise of outstanding options or for any other reason, Detection Acquisition intends to acquire additional shares of Thermedics Detection common stock on the open market or in privately negotiated transactions to the extent required for the aggregate ownership of Thermedics Detection common stock by Thermo Electron and its subsidiaries to equal or exceed 90%. These purchases would be made at market prices or privately negotiated prices at the time of purchase, which may be higher or lower than the price of $8.00 per share in the tender offer and the merger. See "Special Factors--Other Possible Purchases of Shares." - Source of Funds (page 51). The total amount of funds required for Detection Acquisition to purchase all of the outstanding shares of Thermedics Detection common stock pursuant to the tender offer and merger, assuming no outstanding options are exercised, and to pay related expenses - -------------------------------------------------------------------------------- 3 4 - -------------------------------------------------------------------------------- is estimated to be approximately $18.5 million. Detection Acquisition will obtain the funds to purchase the Thermedics Detection common stock in the tender offer and the merger from Thermedics as a loan or a capital contribution. Thermedics intends to use a combination of its own working capital and borrowings from Thermo Electron to fund this loan or capital contribution. Thermo Electron has committed to provide any required loan financing to Thermedics. Because the tender offer and the merger are for cash and Thermedics and Thermo Electron have access to sufficient cash to fund the tender offer and the merger, we do not believe that the financial condition of Thermedics, Thermo Electron, Corpak or Detection Acquisition is relevant to your decision whether to tender your shares in the tender offer. See "Source And Amount Of Funds." - - THERMEDICS' AND THERMO ELECTRON'S POSITION ON THE FAIRNESS OF THE OFFER AND THE MERGER (PAGE 15). - Determinations of Boards of Directors of Thermedics and Thermo Electron. The boards of directors of Thermedics and Thermo Electron determined that the terms of the tender offer and the merger are fair to the stockholders of Thermedics Detection. In considering the fairness of the tender offer and the merger from a financial point of view to Thermedics Detection's stockholders, the boards of directors of Thermedics and Thermo Electron reviewed and relied in part upon an analysis of the ranges of potential values of the shares of Thermedics Detection common stock that resulted from the application of several accepted valuation methodologies. This analysis, including the selection of valuation methodologies, was prepared by J.P. Morgan Securities Inc. and The Beacon Group Capital Services, LLC. J.P. Morgan and The Beacon Group are the financial advisors to Thermedics and Thermo Electron in connection with the tender offer and the merger and the reorganization of Thermo Electron and its subsidiaries described below. For a discussion of the factors that the boards of directors of Thermedics and Thermo Electron considered in making their determinations as to the fairness of the tender offer and the merger and a summary of the financial analysis prepared by J.P. Morgan and The Beacon Group, see "Special Factors--Position Of Thermedics And Thermo Electron As To Fairness Of The Offer And The Merger" and "Special Factors--Summary Of The Advisors' Analysis and Opinion." - Negotiations with Special Committee of Thermedics Detection Board of Directors. The boards of directors of Thermo Electron and Thermedics determined to proceed with the tender offer and short-form merger after negotiations with a special committee of the board of directors of Thermedics Detection with respect to a long-form going private merger did not result in an offer price that the special committee was prepared to recommend to Thermedics Detection's stockholders as a fair price for their shares. A long-form merger requires approval of both the board of directors and stockholders of a company, while a short-form merger may be approved by a stockholder owning 90% or more of a company's outstanding voting securities acting alone. This special committee has informed Thermedics that it has advised the board of directors of Thermedics Detection to recommend that the stockholders of Thermedics Detection reject the tender offer. On February 29, 2000, both members of the special committee resigned from the board of directors of Thermedics Detection. See "Special Factors--Background To The Offer And The Merger--Going Private Merger Discussions." - Potential Conflicts of Interest. Thermedics is the majority stockholder of Thermedics Detection. Thermo Electron is the majority stockholder of Thermedics. Some of the officers and directors of Thermedics and Thermo Electron are also officers or directors of Thermedics Detection and own shares of common stock of, or hold options to purchase shares of common stock of, Thermo Electron, Thermedics and/or Thermedics Detection. As a result, there are various potential or actual conflicts of interest in connection with the tender offer and the merger. See "Special Factors--Conflicts Of Interest." - -------------------------------------------------------------------------------- 4 5 - -------------------------------------------------------------------------------- - - CONSEQUENCES OF THE OFFER AND THE MERGER (PAGE 28). Completion of the tender offer and the merger would have the following consequences: - Thermedics and Thermo Electron would have complete control over Thermedics Detection's business. - Thermedics and Thermo Electron would own 100% of the equity interest in Thermedics Detection's business and would solely have the benefit or detriment of any change in Thermedics Detection's value. - The shares of Thermedics Detection would no longer be listed on the American Stock Exchange. - Thermedics Detection would no longer be subject to the requirements of the Securities Exchange Act of 1934, including requirements to file annual and other periodic reports or to provide the type of going-private disclosure contained in this offer to purchase. If you do not tender your shares of Thermedics Detection common stock and the tender offer is completed, your shares will remain outstanding until the subsequent merger of Detection Acquisition and Thermedics Detection. After the merger, each of your shares will, subject to statutory appraisal rights, be converted into the right to receive $8.00 in cash, without interest. - - APPRAISAL RIGHTS (PAGE 52). If you tender your shares of Thermedics Detection common stock in the tender offer, you will not be entitled to exercise statutory appraisal rights under Massachusetts law. If you do not tender your shares in the tender offer, upon the subsequent merger of Detection Acquisition and Thermedics Detection, you will have a statutory right to dissent and demand payment of the judicially appraised fair value of your Thermedics Detection shares plus a fair rate of interest, if any, from the date of the vote of the board of directors of Detection Acquisition approving the merger. This value may be more or less than the $8.00 per share cash consideration in the tender offer and the merger. See "The Merger; Appraisal Rights." - - PURPOSE OF THE TENDER OFFER (PAGE 13). On January 31, 2000, Thermo Electron announced that its board of directors had authorized its management to proceed with a major reorganization of the operations of Thermo Electron and its subsidiaries. As part of this reorganization, Thermo Electron plans to acquire the public minority interests in most of its subsidiaries that have minority investors, spin off its separation technologies and fiber-based products business and its medical products business and divest a variety of non-core businesses. The primary goal of the reorganization is for Thermo Electron and each of its spun-off subsidiaries to focus on its core business. The purpose of this tender offer and the proposed subsequent merger is to acquire the minority public interest in Thermedics Detection as part of Thermo Electron's overall reorganization and to provide Thermedics Detection's stockholders with $8.00 in cash for each of their shares of Thermedics Detection common stock. Following the tender offer and the merger, Thermo Electron plans to retain Thermedics Detection as part of Thermo Electron's core instrument business. - - FOR MORE INFORMATION (PAGES 44 AND 47).

(the "Purchaser"), a Delaware corporation and an indirect wholly-owned subsidiary of Thermedics Inc., a Massachusetts corporation ("Thermedics"), hereby offers to purchase all outstanding shares of common stock, par value $.10 per share (the "Shares"), of Thermedics Detection Inc., a Massachusetts corporation (the "Company"), at a purchase price of $8.00 per Share (the "Offer Price"), net to the seller in cash, without interest thereon, upon the terms and subject to the conditions set forth in this Offer to Purchase and in the related Letter of Transmittal (which, together with any amendments or supplements hereto or thereto, collectively constitute the "Offer"). The Purchaser is a wholly-owned subsidiary of Corpak Inc., a Massachusetts corporation ("Corpak"). Corpak is a wholly-owned subsidiary of Thermedics. Thermedics is a majority-owned subsidiary of Thermo Electron Corporation, a Delaware corporation ("Thermo Electron"). THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER THAT NUMBER OF SHARES WHICH, TOGETHER WITH THE SHARES OWNED BY THERMO ELECTRON AND ITS SUBSIDIARIES, INCLUDING THERMEDICS, CONSTITUTES AT LEAST NINETY PERCENT (90%) OF THE OUTSTANDING SHARES ON THE EXPIRATION DATE OF THE OFFER (THE "MINIMUM CONDITION"). THE OFFER IS ALSO SUBJECT TO OTHER IMPORTANT TERMS AND CONDITIONS CONTAINED IN THIS OFFER TO PURCHASE. SEE "THE TENDER OFFER--CERTAIN CONDITIONS OF THE OFFER." As of January 28, 2000, there were 19,316,684 Shares outstanding and 1,009,413 Shares reserved for issuance pursuant to options (the "Options") outstanding as of such date under the Company's option plans. As of such date, Corpak owned 16,150,248 Shares, or approximately 83.6% of the outstanding Shares (79.5% assuming all outstanding Options are exercised). Of the Shares owned by Corpak, 97,923 Shares have been reserved for issuance under stock options granted by Thermedics under its stock option plans. As of January 28, 2000, Thermo Electron owned 1,029,950 Shares, or approximately 5.3% of the outstanding Shares (5.1% assuming all outstanding Options are exercised). Of the Shares owned by Thermo Electron, 65,300 Shares have been reserved for issuance under stock options granted under Thermo Electron's stock option plans. Based upon the number of outstanding Shares as of January 28, 2000 and assuming no Options are exercised, 204,818 Shares must be tendered in the Offer in order to satisfy the Minimum Condition. Assuming all outstanding Options are exercised, 1,113,290 Shares must be tendered in the Offer in order to satisfy the Minimum Condition. Tendering stockholders will not be obligated to pay brokerage fees or commissions or, except as otherwise provided in Instruction 6 of the Letter of Transmittal, stock transfer taxes with respect to the purchase by the Purchaser of Shares pursuant to the Offer.

If the Offer is completed, Thermo Electron, Corpak and the Purchaser together will own at least 90% of the Shares. Promptly following the closing of the Offer, Corpak and Thermo Electron plan to contribute their Shares to the Purchaser in exchange for common stock of the Purchaser. Thermo Electron and Corpak would then cause the Company to merge with and into the Purchaser in a so-called "short-form" merger between the Company and the Purchaser (the "Merger"). After the Merger, the Purchaser would be the surviving corporation, would change its name to "Thermedics Detection Inc." and would be owned exclusively by Thermedics, through its ownership of Corpak, and Thermo Electron. Stockholders of the Company who do not tender their Shares in the Offer would not be entitled to vote on the Merger. The consideration per Share in the Merger would be the same as the Offer Price. If, after the Offer is completed but prior to consummation of the Merger, the aggregate ownership by Thermo Electron and its subsidiaries of the outstanding Shares should fall below 90% due to the exercise of outstanding Options or for any other reason, the Purchaser intends to acquire additional Shares on the open market or in privately negotiated transactions to the extent required for such ownership to equal or exceed 90%. Any such purchases would be made at market prices or privately negotiated prices at the time of purchase, which may be higher or lower than the Offer Price. For a discussion of other actions Thermedics and Thermo Electron may take if the Offer is not completed, see "Special Factors--Conduct Of The Company's Business If The Offer Is Not Completed." The Purchaser, Corpak, Thermedics and Thermo Electron have filed with the Securities and Exchange Commission (the "Commission") a Tender Offer Statement on Schedule TO (including the information required by Schedule 13E-3) (the "Schedule TO") under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), relating to the Offer, the Merger and other potential purchases of Shares. 8 9 SPECIAL FACTORS BACKGROUND TO THE OFFER AND THE MERGER THE THERMO ELECTRON REORGANIZATION. On January 31, 2000, Thermo Electron announced that its Board of Directors had authorized its management to proceed with a major reorganization of the operations of Thermo Electron and its subsidiaries. As part of this reorganization, Thermo Electron plans to acquire the public minority interest in most of its subsidiaries that have minority investors, spin off its separation technologies and fiber-based products business and its medical products business and divest a variety of non-core businesses. The primary goal of the reorganization is for Thermo Electron and each of its spun-off subsidiaries to focus on their respective core businesses. The purpose of the Offer and the Merger is to acquire the minority public interest in the Company as part of Thermo Electron's overall reorganization and to provide the public stockholders of the Company with $8.00 per Share in cash. Following the Offer and the Merger, Thermo Electron plans to retain the Company as part of Thermo Electron's core instrument business. THE COMPANY. The Company operates in two segments: Detection Instruments and Laboratory Products. The Company's Detection Instruments segment develops, manufactures and markets high-speed detection and measurements systems used for quality assurance and security applications. The Company's Laboratory Products segment develops, manufactures and markets products used to determine the quality of a wide variety of items, including food, water and pharmaceuticals and to measure the moisture content of raw, in-process and finished products. In addition, the Laboratory Products segment manufactures specific ion-measurement systems that are used to monitor water quality in the power, semiconductor, petrochemical, paper, pharmaceutical and drinking water industries. The Company operated as a division of Thermedics until its incorporation as a Massachusetts corporation in December 1990. The Company completed its initial public offering in March 1997. In the initial public offering, the Company sold 2,671,292 Shares to the public at a price of $11.50 per Share (for net proceeds of $28.1 million). GOING PRIVATE MERGER DISCUSSIONS. In August 1998, Thermo Electron determined that it would benefit from a corporate restructuring that would simplify its corporate structure, consolidate and strategically realign certain businesses and increase the liquidity in the public stock of certain of its publicly traded subsidiaries. Thermo Electron subsequently refined and expanded this proposal and on January 31, 2000 announced the proposed reorganization described above under "--The Thermo Electron Reorganization." As part of the initial restructuring plan, Thermo Electron proposed on August 12, 1998 that Thermedics' majority ownership of the Company be transferred to Thermo Electron in exchange for a portion of the shares of Thermedics common stock held by Thermo Electron. Thermo Electron proposed to then transfer its equity interest in the Company to Thermo Instrument Systems Inc. ("Thermo Instrument"), another majority-owned subsidiary of Thermo Electron. Thermo Instrument would then take the Company private for either cash or shares of Thermo Instrument common stock. On December 10, 1998, Thermo Electron issued a press release announcing revisions to its August 12, 1998 proposal. This revised proposal contemplated that Thermo Electron would take the Company private as a wholly-owned subsidiary of Thermo Electron. To this end, Thermedics proposed to transfer its Shares to Thermo Electron as part of an exchange for Thermo Electron's wholly-owned biomedical group, with Thermo Electron offering the stockholders of the Company other than Thermo Electron and its subsidiaries (the "Public Stockholders") cash in exchange for their Shares. In May 1999, the Board of Directors of the Company formed a special committee (the "Special Committee") to negotiate the terms of the proposed going private transaction with Thermedics and Thermo Electron. The Special Committee initially consisted solely of Matthew Weisman. Subsequently, Matthew Haggerty was added to the Board of Directors of the Company and appointed to the Special Committee. Neither of these individuals was otherwise affiliated with Thermo Electron, Thermedics or any of their subsidiaries other than the Company. In June 1999, the Special Committee retained Swidler Berlin Shereff Friedman, LLP as its legal counsel. 9 10 On July 21, 1999, Mr. Jonathan Wilk, Deputy General Counsel of Thermo Electron, provided a memorandum to the Special Committee which summarized the proposed structure of the acquisition of the outstanding Shares of the Company by Thermo Electron and Thermedics. In August 1999, the Special Committee engaged Banc of America Securities, LLC ("Banc of America") as its financial advisor in connection with the proposed transaction. On August 30, 1999, Mr. Theo Melas-Kyriazi, the Chief Financial Officer of Thermo Electron, Thermedics and the Company, provided the Special Committee with a written proposal by Thermo Electron (the "August 30 Offer") to acquire all of the outstanding Shares through a merger at a price of $9.50 per Share in cash. The August 30 Offer was subject to the approval by the Boards of Directors of Thermo Electron and Thermedics. Mr. Melas-Kyriazi indicated that the price of $9.50 per Share was based upon the following considerations: - The price of $9.50 represented a 25% premium over the price of the Shares on December 9, 1998, the day before Thermo Electron announced the proposed cash going private transaction regarding the Company. - The price was higher than the range of values per Share calculated by Thermo Electron using a discounted cash flow analysis. Thermo Electron calculated the cash flows that the Company was expected to generate during fiscal 1999 through 2003 based on the financial projections for fiscal 1999 and 2000 prepared by the Company as part of its normal operations (the "1999-2000 Projections") and projections prepared by Thermo Electron, with the assistance of management of the Company, for fiscal 2001 through 2003 (the "2001-2003 Projections"). Thermo Electron also calculated a range of terminal asset values of the Company at the end of the five-year period ending in fiscal 2003 by applying a multiple of ten times earnings before interest and taxes ("EBIT"), a multiple of nine times earnings before interest, taxes, amortization and depreciation ("EBITDA") and a multiple of 15 times net earnings. The cash flows and ranges of terminal asset values were then discounted to present values using discount rates of 15% and 17.5%. The present value of the cash flows and the range of terminal asset values were then adjusted for the Company's estimated 1999 fiscal year-end excess cash, option exercise proceeds and total debt. This discounted cash flow analysis prepared by Thermo Electron indicated a range of values of between $7.04 and $7.49 per Share based on an EBIT discounted cash flow analysis, $7.44 and $7.92 per Share based on an EBITDA discounted cash flow analysis and $7.02 and $7.46 per Share based on a net earnings discounted cash flow analysis, resulting in an average discounted cash flow range of values of between $7.17 and $7.62 per Share. See "--Certain Projected Financial Data." - The price was higher than $5.84, which was the median of the range of values per Share from $4.20 to $10.15 calculated by Thermo Electron using an analysis of multiples of EBIT, EBITDA, book value, net earnings and revenues of the following publicly-traded companies that Thermo Electron considered comparable to the Company: Mettler-Toledo International, Inc., Barringer Technologies, Inc., Invision Technologies, Inc., Vivid Technologies, Inc., American Science and Engineering Inc. and Fairey Group, plc. During September and October 1999, Banc of America conducted a financial due diligence review of the Company and the proposed transaction on behalf of the Special Committee. During a telephone conversation on September 30, 1999, Mr. R.C. Smith of Banc of America informed Mr. Melas-Kyriazi of Mr. Smith's opinion that discounted cash flow and comparable companies value analyses of the Company were not appropriate due to disagreements between Thermo Electron and the Company's management regarding the role that acquisitions would play in the growth strategy for the Company. Mr. Smith informed Mr. Melas-Kyriazi that the Special Committee expected a greater premium over the pre-announcement market price of the Shares. On November 9, 1999, Mr. Melas-Kyriazi met with the Special Committee. The Special Committee informed Mr. Melas-Kyriazi that the August 30 Offer was not acceptable. The Special Committee reiterated the concerns and views previously expressed by Mr. Smith. 10 11 On November 18, 1999, Mr. Melas-Kyriazi met with the Special Committee and representatives of Banc of America. The Special Committee again informed Mr. Melas-Kyriazi that the August 30 Offer was not acceptable and that Thermo Electron and Thermedics should pay a "customary" premium of at least 25% over the then current market price. The Special Committee requested that Thermo Electron and Thermedics increase their offer accordingly. During a telephone conversation in December 1999, Mr. Melas-Kyriazi reiterated the August 30 Offer to Mr. Haggerty, but Mr. Haggerty indicated that the August 30 Offer remained unacceptable. In December 1999, Thermo Electron retained J.P. Morgan and The Beacon Group as its financial advisors for the purpose of advising Thermo Electron in connection with its strategic alternatives, including advising Thermo Electron in connection with the acquisition of the minority public interest in the Company. On January 12, 2000, Mr. Melas-Kyriazi stated to Mr. Haggerty that the parties needed to agree on a method of proceeding to a resolution of the terms of the transaction. On a number of occasions on or about January 14, 2000, J.P. Morgan and The Beacon Group discussed with the management of Thermo Electron the preliminary results of their analysis of the ranges of potential values of the Shares that resulted from the application of several accepted valuation methodologies. J.P. Morgan and The Beacon Group subsequently presented the results of their analysis to the Thermo Electron Board of Directors on January 18, 2000 and January 28, 2000 and to the Thermedics Board of Directors on January 25, 2000 and January 29, 2000. J.P. Morgan's and The Beacon Group's analysis indicated an estimated range of equity values for the Shares of approximately $6.75 to $8.00 per Share based on an analysis of the trading value of comparable companies, between $7.00 and $8.50 per Share based on an analysis of comparable buy-out transactions and between $7.00 and $8.25 per Share based on an analysis of discounted cash flows. See "--Summary Of The Advisors' Analysis and Opinion." On January 21, 2000, Mr. Melas-Kyriazi submitted a revised offer of $8.00 per Share orally to counsel for the Special Committee, subject to approval of the Boards of Directors of Thermo Electron and Thermedics. On the same day, Mr. Wilk sent a letter to counsel for the Special Committee that confirmed the terms of the oral offer made by Mr. Melas-Kyriazi revising Thermedics' and Thermo Electron's existing offer to $8.00 per Share and indicating Thermedics' and Thermo Electron's willingness to condition a merger upon the approval of a majority of the Shares held by the Public Stockholders (the "January 21 Offer"). Mr. Wilk's letter stated that the offer would expire at noon on January 25, 2000. On January 24, 2000, counsel for the Special Committee telephoned Mr. Wilk and informed him that the Special Committee would not be in a position to respond to the January 21 Offer by January 25, 2000. On January 26, 2000, Mr. Weisman sent a letter to Dr. Richard F. Syron, the Chairman and Chief Executive Officer of Thermo Electron, stating that the "Special Committee [was] unprepared to recommend this down offer to minority shareholders." The Special Committee expressed frustration with the pace of the negotiations and asserted that Thermo Electron had been unresponsive to the Special Committee's concerns. The Special Committee also asserted that representatives of Thermo Electron had failed to consider certain qualitative factors in valuing the Shares held by the Public Stockholders. The Special Committee requested a meeting with Dr. Syron to discuss such qualitative factors. Because the Special Committee did not accept the January 21 Offer, Thermedics and Thermo Electron determined not to proceed with negotiation of a long-form merger with the Special Committee but instead to initiate the Offer and the Merger. On January 29, 2000, the Special Committee sent a report to the Board of Directors of the Company. The report reviewed the history of the formation of the Special Committee, its meetings with legal and financial advisors, the August 30 Offer and the January 21 Offer. The report further provided in part: "In November 1999 the Special Committee met alone with Theo Melas-Kyriazi, Chief Financial Officer of Thermo Electron, to discuss the Thermo Electron offer, and then again with Mr. Melas-Kyriazi, this time with its financial advisor. The Special Committee informed Mr. Melas-Kyriazi that, based upon the financial analysis performed by its financial advisor, the $9.50 offer price was 11 12 inadequate and requested that Thermo Electron increase its offer. The Special Committee believed then and now that Thermo Electron considered only certain quantitative factors in its analysis of the proposed offer price for the minority stockholders and did not consider qualitative factors. Thermo Electron did not respond to the Special Committee's request until last Friday, January 21, 2000, approximately two months after the meeting with Mr. Melas-Kyriazi, and then with a decreased offer of $8.00 per share. The lower offer was accompanied by a deadline to respond to that offer by midday Tuesday, January 25, 2000. In a letter sent by Matthew Weisman on behalf of the Special Committee on January 26, 2000 to Richard Syron, Chairman and Chief Executive of Thermo Electron, Mr. Weisman indicated that the Special Committee was unprepared to recommend this decreased offer to the minority stockholders and also requested a meeting with Mr. Syron to discuss the qualitative factors that it believes have not been properly considered in the valuation of [Thermedics Detection] by Thermo Electron." Also on January 29, 2000, the Company's Board of Directors held a meeting by telephone conference call at which representatives of Thermedics and Thermo Electron described their intention to initiate the Offer and the Merger. On January 31, 2000, Thermedics and Thermo Electron issued a press release announcing the Offer and the Merger. On February 16, 2000, the Special Committee distributed a memorandum to the Board of Directors of the Company designated as the final report of the Special Committee. The memorandum provided in part: "As we stated in the January 29th Report, it is our continuing position that we are unprepared to recommend to the minority stockholders the $8.00 offer price. We believe that there are several factors that were not considered by Thermo Electron/Thermedics in their valuation analysis of the minority stockholders' interests. As we indicated in the January 29th Report, despite repeated attempts on the part of the Special Committee after our November 1999 meetings with Theo Melas-Kyriazi, Chief Financial Officer of Thermo Electron, Thermo Electron was unwilling to engage in any negotiation with respect to its original offer and, on January 21, 2000, reduced its offer to $8.00. Further, on January 26, 2000 we sent a letter to Richard Syron, Chairman and Chief Executive Officer of Thermo Electron, expressing our frustration with Thermo Electron's responsiveness and requesting a meeting with him to discuss the situation. We believe that the factors set forth below have undermined the market value of [Thermedics Detection] common stock and thereby prevented the minority stockholders from obtaining an adequate value for their shares. We believe that these factors have not been properly considered by Thermo Electron/Thermedics. 1. From the time of raising approximately $20 million in its initial public offering on a business plan premised, in part, on acquisition growth, none of the funds raised in that offering have been employed for that purpose. 2. The management of Thermo Electron blocked moving forward on acquisition opportunities available to [Thermedics Detection], despite the recommendations of [Thermedics Detection] management and without advising the independent directors of [Thermedics Detection] to participate in a Board review.... 3. Without advising the independent directors of [Thermedics Detection], management of Thermo Electron limited capital expenditures recommended by management of [Thermedics Detection], which research and development likely would have enhanced the value of [Thermedics Detection]. 4. With the uncertainty surrounding the proposed buy-out and the resulting loss of focus of management, the performance of [Thermedics Detection] has deteriorated and contributed to a dramatic drop in the price of [Thermedics Detection's] stock. 12 13 5. The inordinate length of time since the announcement of the buyout of [Thermedics Detection] by Thermo Electron (August 1998) has added uncertainty to [Thermedics Detection's] situation and provided an extended period during which [Thermedics Detection's] share price could, and did, decline. a) The inordinate length of time it took Thermo Electron to appoint a special committee (the functioning special committee, as it is constituted today, was not appointed until mid-July 1999). b) The lack of responsiveness by Thermo Electron to the request for information as part of the due diligence process undertaken by the advisers to the Special Committee. c) The lack of responsiveness to the Special Committee's November 1999 request for a revised and an increased offer for the minority stockholders' shares.... Based on the foregoing, it is the recommendation of the Special Committee that the Board of Directors of [Thermedics Detection] advise the minority stockholders of [Thermedics Detection] to reject the Thermedics tender offer." At a meeting of the Company's Board of Directors held on February 18, 2000, the Special Committee presented its report to the members of the Company's Board of Directors. On February 29, 2000, the members of the Special Committee resigned as directors of the Company. At a meeting on March 8, 2000, the Company's Board of Directors determined that the Company would not make a recommendation as to whether the Public Stockholders should tender their Shares pursuant to the terms of the Offer. On March 10, 2000, the Purchaser commenced the Offer. REASONS FOR THE OFFER AND THE MERGER ACTIONS OF THERMEDICS' BOARD OF DIRECTORS. On January 25, 2000 and January 29, 2000, the Board of Directors of Thermedics held meetings at which the proposed plan to acquire the minority stockholder interest in the Company through the Offer and the Merger was presented and discussed. Messrs. George N. Hatsopoulos, John N. Hatsopoulos, John T. Keiser and John W. Wood, Jr., members of Thermedics' Board of Directors, initially took part in each of these meetings, but recused themselves from discussions of the terms of the Offer and the Merger and from voting to approve the Offer. These directors recused themselves because they were also officers or directors of the Company or hold Shares or options to purchase Shares. No director of Thermedics present for the vote approving the Offer objected to or abstained from such vote. Dr. Richard F. Syron, a member of the Board of Directors of Thermedics at the time of the vote, resigned as a director of Thermedics effective March 7, 2000. BENEFITS AND DETRIMENTS TO THE COMPANY OF THE OFFER AND THE MERGER. In determining whether to make the Offer and thereafter effect the Merger, the Thermedics Board of Directors considered several factors, including the financial performance and profitability of the Company and the potential benefits to the Company's business if the Company were to become part of a larger business unit. Thermedics' Board of Directors also considered the following factors: - the prospect of achieving greater marketing, operating and administrative efficiency as a result of the Company's operations being conducted in a more coordinated manner with Thermo Electron's other instruments subsidiaries; - the reduction in the amount of public information available to competitors about the Company's businesses that would result from the termination of the Company's obligations under the reporting requirements of the Commission; - the elimination of additional burdens on management associated with public reporting and other tasks resulting from the Company's public company status, including, for example, the dedication of time by and resources of the Company's management and Board of Directors to stockholder and analyst inquiries and investor and public relations; 13 14 - the decrease in costs, particularly those associated with being a public company (for example, as a privately-held entity, the Company would no longer be required to file quarterly, annual or other periodic reports with the Commission or publish and distribute to its stockholders annual reports and proxy statements), that Thermo Electron and Thermedics anticipate could result in savings of approximately $450,000 per year, including fees for an audit by an independent accounting firm and legal fees; - the greater flexibility that the Company's management would have to focus on long-term business goals, as opposed to quarterly earnings, as a non-reporting company, particularly in light of the potential volatility in the Company's quarterly earnings; and - recent public capital market trends affecting small-cap companies, including perceived lack of interest by institutional investors in companies with a limited public float. The Board of Directors of Thermedics also considered the advantages and disadvantages of certain alternatives to acquiring the minority stockholder interest in the Company, including: - a sale of its equity interest in the Company; and - leaving the Company as a majority-owned, public subsidiary. The first alternative, selling Thermedics' equity interests in the Company, was briefly considered. It was not an alternative that was pursued at length, given that Thermo Electron did not want to sell, and did not want Thermedics to sell, its equity interest in the Company, but rather intended to retain the Company as a part of Thermo Electron's core instrument businesses. In the view of the Board of Directors of Thermedics, the principal advantage of leaving the Company as a majority-owned, public subsidiary of Thermedics was the ability of Thermedics to invest the cash that would be required to buy the minority stockholder interest in the Company for other purposes. The disadvantages of leaving the Company as a majority-owned, public subsidiary which were considered by the Board of Directors of Thermedics included the inability to achieve many of the benefits of taking the Company private discussed above. The Board of Directors of Thermedics concluded that the advantages of leaving the Company as a majority-owned, public subsidiary of Thermedics were significantly outweighed by the disadvantages of doing so, and accordingly that alternative was rejected. CONSIDERATION OF LIQUIDITY AND SHARE PRICE; TIMING. The Board of Directors of Thermedics also considered the relatively low volume of trading in the Shares and considered that the Offer and the Merger would result in immediate, enhanced liquidity for the Public Stockholders. The Board of Directors of Thermedics considered trends in the price of the Shares in the past twelve months and during the period between the Company's initial public offering and the announcement of Thermedics' intention to take the Company private. Thermedics and Thermo Electron have determined to make the Offer and effect the Merger at this time as part of the larger reorganization of Thermo Electron and its subsidiaries. The Company's stock price was not a significant factor in the timing of Thermedics' and Thermo Electron's decision to acquire the minority stockholder interest in the Company. ALTERNATIVE STRUCTURE CONSIDERED. The Board of Directors of Thermedics also considered whether to structure the transaction as a tender offer followed by a short-form merger or as a long-form merger. In determining to structure the transaction as a tender offer followed by a short-form merger, the Board of Directors considered the following: - The discussions with the Special Committee with respect to a long-form merger were progressing at a pace that the Thermedics Board of Directors did not consider acceptable. See "--Background To The Offer And The Merger--Going Private Merger Discussions." - Unless at least 90% of the outstanding Shares are owned by the Purchaser, it could not effect a short-form merger. Unlike a long-form merger, the approval of the Company's Board of Directors is not required to complete a short-form merger. Consequently, once the Special Committee determined not 14 15 to recommend the long-form merger contemplated by the January 21 Offer, the Offer and the Merger potentially enabled Thermedics and Thermo Electron to acquire all of the Shares without the approval of the Board of Directors of the Company or the Special Committee. - A tender offer followed by a short-form merger would permit Thermedics and Thermo Electron to acquire the minority interest in the Company on an expeditious basis and provide the Public Stockholders with a prompt opportunity to receive the Offer Price of $8.00 per Share. - In the Offer, each Public Stockholder would individually determine whether to accept the Offer Price of $8.00 per Share. - Public Stockholders who do not tender their Shares in the Offer could preserve their appraisal rights in the Merger under state law. After discussing the advantages and disadvantages of acquiring the minority stockholder interest in the Company, including the alternative method of acquiring such interests through a long-form merger, the Thermedics Board of Directors authorized taking the Company private through a tender offer for all of the Shares of the Company that Thermo Electron and its subsidiaries, including Thermedics, did not already own, at a price per Share of $8.00 in cash, to be followed by a short-form merger at the same price. ACTIONS OF THERMO ELECTRON'S BOARD OF DIRECTORS. On January 18, 2000 and January 28, 2000, the Board of Directors of Thermo Electron held special meetings at which Thermo Electron's management presented the proposal for Thermedics to acquire all of the Shares that Thermo Electron and its subsidiaries did not already own as a part of the proposed corporate reorganization of Thermo Electron and certain of its subsidiaries. Messrs. George N. Hatsopoulos, John N. Hatsopoulos, Elias P. Gyftopoulos and Robert A. McCabe, members of Thermo Electron's Board of Directors, initially took part in each of these meetings but recused themselves from discussions of the terms of the Offer and the Merger and from taking action with respect to the Offer. These directors recused themselves because they hold Shares or Options to purchase Shares. The Board of Directors of Thermo Electron considered all of the factors relating to the Offer and the Merger referred to above that were considered by Thermedics' Board of Directors. The Board of Directors of Thermo Electron also discussed the fact that the acquisition by Thermedics of the minority stockholder interest in the Company would advance the goal of Thermo Electron's proposed corporate reorganization. After consideration of these factors, the Board of Directors of Thermo Electron resolved that it would not object if Thermedics determined to take the Company private through Thermedics' acquisition for cash through the Offer and the Merger of all of the Shares held by the Public Stockholders at a purchase price of $8.00 per Share. No director of Thermo Electron present to vote on the resolution not to object if Thermedics determined to effect the Offer and the Merger objected to or abstained from such vote. POSITION OF THERMEDICS AND THERMO ELECTRON AS TO FAIRNESS OF THE OFFER AND THE MERGER Because Corpak and Thermo Electron together currently own a majority of the Shares, Thermo Electron, Thermedics, Corpak and the Purchaser are deemed "affiliates" of the Company under Rule 12b-2 of the Exchange Act. Accordingly, in compliance with Rule 13e-3 under the Exchange Act, the Boards of Directors of Thermedics and Thermo Electron have considered the fairness of the Offer and the Merger to the Public Stockholders. DETERMINATIONS OF THE BOARDS OF DIRECTORS OF THERMEDICS AND THERMO ELECTRON. In authorizing the Offer and the Merger, the Board of Directors of each of Thermedics and Thermo Electron determined that the Offer and the Merger are fair to the Public Stockholders. In reaching their determinations that the terms of the Offer and the Merger are fair to the Public Stockholders, the Boards of Directors of Thermedics and Thermo Electron considered the factors set forth under this section captioned "Position of Thermedics And Thermo Electron As To Fairness Of The Offer And The Merger," which constitute all of the material factors considered by the Boards of Directors of Thermedics and Thermo Electron in making their determinations. 15 16 The Boards of Directors of Thermedics and Thermo Electron determined that each of the following factors supported their belief that the Offer and the Merger are fair to the Public Stockholders: - Financial analysis. In considering the fairness of the Offer and the Merger from a financial point of view to the Company's stockholders, including the Public Stockholders, the Boards of Directors of Thermedics and Thermo Electron reviewed and relied in part upon an analysis of the ranges of potential values of the Shares that result from the application of several accepted valuation methodologies. This financial analysis, including the selection of valuation methodologies, was prepared by J.P. Morgan and The Beacon Group (the "Advisors") to assist the Boards of Directors of Thermedics and Thermo Electron with their evaluation of the Offer and the Merger. Thermo Electron retained J.P. Morgan and The Beacon Group as its financial advisors for the purpose of advising Thermo Electron in connection with its strategic alternatives, including advising Thermo Electron and Thermedics in connection with the acquisition of the minority interest in the Company. The financial analyses undertaken by the Advisors included an analysis based upon public trading multiples, comparable buy-out transactions and discounted cash flows. The analysis of trading multiples of companies engaged in businesses which the Advisors judged to be analogous to the Company's business indicated an estimated range of equity values for the Shares of approximately $6.75 to $8.00 per Share. The analysis of other buyout transactions indicated an estimated range of equity values for the Shares of between $7.00 and $8.50 per Share. The analysis based upon discounted cash flows indicated an estimated range of equity values for the Shares of between $7.00 and $8.25 per Share. See "--Summary of The Advisors' Analysis and Opinion." - Information concerning the financial performance, condition, business operations and prospects of the Company. The Boards of Directors of Thermedics and Thermo Electron believed the Offer Price to be attractive in light of the Company's current financial performance, profitability and growth prospects. In addition, the Offer and the Merger would shift the risk of the future financial performance of the Company from the Public Stockholders, who do not have the power to control decisions made as to the Company's business, entirely to Thermedics and Thermo Electron, who do have the power to control the Company's business and who have the resources to manage and bear the risks inherent in the business over the long term. See "--Certain Projected Financial Data." - The premium reflected in the Offer Price of $8.00 per Share. The Boards of Directors of Thermedics and Thermo Electron considered the current and historical trading prices of the Shares. The market price of the Shares had declined from $11.875 on March 20, 1997, the date of the Company's initial public offering, to $7.1875 on August 11, 1998, the trading date immediately prior to Thermo Electron's announcement of its intention to take the Company private for cash or stock, and to $7.625 on December 9, 1998, the trading date immediately prior to Thermo Electron's announcement of its intention to take the Company private for cash. The Offer Price represented a premium of 11.3% over the closing price on August 11, 1998. The purchase by Thermedics would eliminate the exposure of the Public Stockholders to any future or continued declines in the price of the Shares. The Boards of Directors of Thermedics and Thermo Electron believed that the market price of the Shares after the August 12, 1998 announcement reflected the financial markets' anticipation of the consideration that would be paid to the Public Stockholders in a going private transaction. See "--Certain Effects Of The Offer And The Merger." - Terms of the Offer. The Boards of Directors of Thermedics and Thermo Electron considered the terms of the Offer and the Merger, including (1) the amount and form of the consideration, (2) the limited number of conditions to the obligations of the Purchaser, including the absence of a financing condition, (3) the tender offer structure, which would provide an expeditious means for the Public Stockholders to receive the Offer Price and (4) the Minimum Condition. - The market price and relative lack of liquidity for the Shares and the liquidity that would be realized by the Public Stockholders from the all-cash Offer. The Boards of Directors of Thermedics and Thermo Electron believed that the liquidity that would result from the Offer and the Merger would be beneficial to the Public Stockholders because Thermedics' and Thermo Electron's combined signifi 16 17 cant ownership of Shares (1) results in a relatively small public float that necessarily limits the amount of trading in the Shares and (2) decreases the likelihood that a proposal to acquire the Shares would be made by an independent entity without the consent of Thermedics and Thermo Electron. - Thermo Electron's and Thermedics' determination to retain their majority ownership of the Company and not to seek a third party buyer for the Company. Thermedics and Thermo Electron stated their current intention to retain their majority holdings in the Company, which foreclosed the opportunity to consider an alternative transaction with a third party purchaser of the Company or otherwise provide liquidity to the Public Stockholders. Accordingly, it is unlikely that finding a third party buyer for the Company was a realistic option for the Public Stockholders. Neither Thermedics nor Thermo Electron solicited or received an offer for the Company from a third party in the prior two years. PROCEDURAL FAIRNESS. The Boards of Directors of Thermedics and Thermo Electron also determined that the Offer and the Merger are procedurally fair to the Public Stockholders. In making such determination, the Boards of Directors considered the following factors: - Each Public Stockholder can individually determine whether to tender Shares in the Offer. - The Offer provides the opportunity for the Public Stockholders to sell their Shares without incurring brokerage and other costs typically associated with market sales. - In determining the Offer Price, the Boards of Directors of Thermedics and Thermo Electron relied in part upon an analysis prepared by the Advisors of the ranges of potential values of the Shares that resulted from the application of several accepted valuation methodologies. See "--Summary Of The Advisors' Analysis and Opinion." - Public Stockholders who believe that the terms of the Offer and the Merger are not fair can pursue appraisal rights in the Merger under state law. CERTAIN NEGATIVE CONSIDERATIONS. The Boards of Directors of Thermedics and Thermo Electron also considered the following factors, each of which they considered to be negative, in their deliberations concerning the fairness of the terms of the Offer and the Merger: - Termination of participation in future growth of the Company. Following the successful completion of the Offer and the Merger, the Public Stockholders would cease to participate in the future earnings or growth, if any, of the Company or benefit from increases, if any, in the value of their holdings in the Company. - Conflicts of Interest. The financial interests of Thermo Electron and Thermedics are adverse as to the Offer Price to the financial interests of the Public Stockholders. In addition, officers and directors of the Company have actual or potential conflicts of interest in connection with the Offer and the Merger. See "--Conflicts Of Interest." - No Public Stockholder Approval. The Offer and the Merger do not provide the Public Stockholders with an opportunity to vote on the proposed transaction. - Inability to Reach Agreement with Special Committee. The Boards of Directors of Thermedics and Thermo Electron considered the negotiations that had taken place with the Special Committee concerning a possible long-form merger, the proposals the Special Committee had made for the terms of such a merger and the fact that the Special Committee had objected to the negotiations process and determined not to recommend such a merger at the Offer Price. See "--Background To The Offer And The Merger--Going Private Merger Discussions." - No Unaffiliated Representative or Independent Director Approval. The majority of the members of the Board of Directors of the Company who are not employees of the Company have not retained an unaffiliated representative to act solely on behalf of the Public Stockholders for purposes of negotiating the terms of the Offer and the Merger or preparing a report concerning the fairness of the Offer and the Merger. In addition, such majority of the independent members of the Company's Board of Directors 17 18 have not approved the Offer or the Merger. The Special Committee prepared a report recommending that the Company's Board of Directors recommend that the Public Stockholders reject the Offer. OTHER FACTORS. The Boards of Directors of Thermedics and Thermo Electron did not consider the net book value of the Company as a relevant factor in assessing the Company's value and, accordingly, did not evaluate the fairness of the Offer Price in relation to the Company's net book value. The Company's net book value at January 1, 2000 was approximately $121.7 million, which would have yielded a per Share valuation for the Company of $6.30. The Boards of Directors relied in part upon valuation methodologies selected by the Advisors for the purpose of their financial analysis, and the Boards of Directors of Thermedics and Thermo Electron noted that the Advisors did not employ net book value in their financial analysis. Moreover, the Boards of Directors of Thermedics and Thermo Electron do not believe that an analysis based upon net book value is appropriate for an instrument business. The Boards of Directors of Thermedics and Thermo Electron believe that net book value is a valuation methodology more typically used in the banking, utilities, real estate and financial services industries. The Boards of Directors of Thermedics and Thermo Electron also did not consider "shopping" the Company to prospective purchasers. Shopping the Company would not only entail substantial time delays and allocation of management's time and energy, but would also disrupt and discourage the Company's employees and create uncertainty among the Company's customers and suppliers. Furthermore, Thermedics and Thermo Electron do not intend to sell the Company, but rather intend to continue to operate the Company as part of Thermo Electron's core instrument businesses. The Boards of Directors of Thermedics and Thermo Electron did not consider the Offer Price as compared to any implied liquidation value because it was not contemplated that the Company be liquidated, whether or not the Offer and the Merger were completed. See "--Conduct Of The Company's Business After The Offer And The Merger." RECENT PURCHASES OF SHARES BY THERMO ELECTRON AND THERMEDICS. See Schedule II to this Offer to Purchase for information on purchases of Shares by Thermo Electron, Thermedics and the Company during the past two years. These Share acquisitions include purchases at prices exceeding the Offer Price. CONCLUSIONS OF THE BOARDS OF DIRECTORS. The Thermedics and Thermo Electron Boards of Directors concluded that, given the performance of the Shares between the Company's initial public offering and the announcement of Thermedics' intention to take the Company private, the uncertainties surrounding the Company's future growth prospects and the limited trading market for the Shares, the Offer and Merger would result in a fair treatment of the Public Stockholders. In determining that the Offer and the Merger are fair to the Public Stockholders, the Boards of Directors of Thermedics and Thermo Electron considered the above factors as a whole and did not assign specific or relative weights to them, other than that the Offer Price of $8.00 per Share in cash was considered the most important factor. In making the determination as to fairness, Thermedics and Thermo Electron also had access to the 1999-2000 Projections and to financial projections for the fourth quarter of fiscal 1999 and for fiscal 1999 and 2000 prepared by the Company (the "2000 Projections"). See "--Certain Projected Financial Data." SUMMARY OF THE ADVISORS' ANALYSIS AND OPINION Thermo Electron retained J.P. Morgan and The Beacon Group as its exclusive financial advisors for the purpose of advising Thermo Electron in connection with its strategic alternatives, including advising Thermo Electron and Thermedics in connection with the acquisition of the minority interest in the Company. On a number of occasions on or about January 14, 2000, the Advisors discussed with the management of Thermo Electron the preliminary results of their analysis of the ranges of potential values of the Shares that resulted from the application of several accepted valuation methodologies. The Advisors subsequently presented an analysis to the Thermo Electron Board of Directors on January 18, 2000 and January 28, 2000 and to the Thermedics Board of Directors on January 25, 2000 and January 29, 2000. This financial analysis, including the selection of valuation methodologies, was prepared by the Advisors to assist the Boards of Directors of Thermedics and Thermo Electron with their evaluation of the Offer and the Merger. At the January 28, 2000 and January 29, 2000 meetings of the Boards of Thermo Electron and Thermedics, respectively, the Advisors also orally delivered their opinion (the "Opinion"), subsequently confirmed in a written opinion dated 18 19 January 29, 2000, that, as of such date and based upon and subject to the various factors, assumptions and limitations set forth in their Opinion, the consideration of $8.00 net per Share in cash to be paid pursuant to the Offer and the Merger was fair from a financial point of view to Thermedics and Thermo Electron. THE ADVISORS' FINANCIAL ANALYSIS AND RELATED OPINION WAS PROVIDED TO THE BOARDS OF DIRECTORS OF THERMEDICS AND THERMO ELECTRON. THE OPINION IS DIRECTED ONLY TO THE FAIRNESS OF THE CONSIDERATION FROM A FINANCIAL POINT OF VIEW TO THERMEDICS AND THERMO ELECTRON (AND NOT TO THE PUBLIC STOCKHOLDERS) AND DOES NOT CONSTITUTE A RECOMMENDATION AS TO WHETHER OR NOT THE PUBLIC STOCKHOLDERS SHOULD TENDER THEIR SHARES IN THE OFFER. In conducting their financial analysis and rendering their Opinion, the Advisors reviewed, among other things: - the audited financial statements of the Company, Thermedics and Thermo Electron for the fiscal year ended January 2, 1999; - the unaudited financial statements of the Company, Thermedics and Thermo Electron for the period ended October 2, 1999; - current and historical market prices of the Shares; - certain publicly available information concerning the business of the Company and of certain other companies engaged in businesses deemed by the Advisors to be comparable to those of the Company; - the reported market prices for securities of certain other companies deemed by the Advisors to be comparable to the Company; - publicly available terms of certain transactions involving companies deemed by the Advisors to be comparable to the Company and the consideration paid for such companies; - the terms of other business combinations deemed relevant by the Advisors; - the 2000 Projections; and - certain agreements with respect to outstanding indebtedness or obligations of the Company, Thermedics and Thermo Electron. The Advisors also held discussions with certain members of the management of Thermedics and Thermo Electron with respect to certain aspects of the Offer and the Merger. In addition, the Advisors held discussions with certain members of management of Thermedics and Thermo Electron with respect to the past and current business operations of the Company, the financial condition and future prospects and operations of the Company and certain other matters believed necessary or appropriate to the Advisors' inquiry. In addition, the Advisors reviewed such other financial studies and analyses and considered such other information as the Advisors deemed appropriate for the purposes of their financial analysis and Opinion. The 2000 Projections were the only non-public information prepared by the Company which were reviewed by the Advisors, and the Advisors did not hold any discussions with management of the Company. No limitation was placed upon the scope of the Advisors' investigation or valuation methodologies by Thermedics or Thermo Electron. The Advisors relied upon and assumed, without independent verification, the accuracy and completeness of all information that was publicly available or that was furnished to, or discussed with, the Advisors by Thermedics, Thermo Electron and the Company or otherwise reviewed by the Advisors, and the Advisors have not assumed any responsibility or liability therefor. The Advisors also assumed that there have been no material changes in the Company's condition, results of operations, business or prospects since the date of the most recent financial statements made available to the Advisors. The Advisors have not conducted, and did not assume any responsibility for conducting, any valuation, appraisal or physical inspection of any of the Company's assets or liabilities (contingent or otherwise), nor have any valuations or appraisals been provided to the Advisors. In relying on the financial analyses, projections and estimates provided to, or discussed with, the Advisors, the Advisors have assumed that they have been reasonably prepared based on assumptions 19 20 reflecting the best currently available estimates and judgments by management as to the expected future financial performance of the Company. The 2000 Projections used by the Advisors were prepared by management of the Company. None of the Company, Thermedics or Thermo Electron publicly discloses internal management projections of the type used by the Advisors in connection with the Advisors' analysis of the Offer and the Merger, and such projections were not prepared with a view toward public disclosure. The 2000 Projections and the additional projections prepared by the Advisors were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of the management of the Company, Thermo Electron and Thermedics, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such projections. See "--Certain Projected Financial Data." The Advisors' financial analysis and Opinion are necessarily based on economic, market and other conditions as in effect on, and the information made available to the Advisors as of, the date of their Opinion. Subsequent developments may affect the financial analysis and the conclusions in the Opinion, and the Advisors do not have any obligation to update, revise or reaffirm their financial analysis or Opinion. In accordance with customary investment banking practice, the Advisors employed generally accepted valuation methods in conducting their financial analysis and reaching their Opinion. In undertaking their analysis, the Advisors primarily relied on three valuation methodologies: comparable public trading multiples, comparable transaction analysis and discounted cash flow analysis. However, with respect to one of the Company's businesses, TMD Detection Consolidated ("Consolidated"), the Advisors considered these methods inappropriate due to its recent poor financial performance. The Advisors therefore excluded the financial results of Consolidated for the purposes of applying such valuation methodologies to the projected financial results of the Company. The effect of such exclusion was to reduce the estimated revenues of the Company for 1999 and 2000 by approximately 23% and to significantly increase the Company's estimated net income for 1999 and 2000 by eliminating Consolidated's operating loss. A value was estimated for Consolidated, which represented less than 10% of the Company's estimated value, and then reincorporated into the financial analysis to derive the equity value range per Share for each valuation methodology. The following is a summary of the material financial analyses undertaken by the Advisors with respect to the Company and presented to the Boards of Directors of Thermo Electron and Thermedics: Public Trading Multiples. Using publicly available information, the Advisors compared selected financial data of the Company with similar data for selected publicly traded companies engaged in businesses which the Advisors judged to be analogous to the Company's business. The companies selected by the Advisors were Mettler-Toledo International, Inc., Ametek Inc., O.I. Corporation and CEM Corporation (the share price of CEM Corporation used in the analysis was as of a date prior to the announcement of its acquisition). These companies were selected, among other reasons, because they compete in similar industries with fairly similar competitive dynamics and growth potential. For each comparable company, publicly available financial performance through the most recent last twelve months was measured. In addition, the Advisors derived estimates of sales, EBITDA, EBIT and net income for the year ended December 31, 2000 for each comparable company from the Institutional Brokers Estimates System. The Advisors applied a range of multiples derived from such analysis to the Company's estimated (based upon the 2000 Projections) sales, EBITDA, EBIT and net income for fiscal 1999 and 2000, and arrived at an estimated range of equity values for the Shares of approximately $6.75 to $8.00 per Share. Selected Transaction Analysis. Using publicly available information, the Advisors examined five selected transactions in which companies engaged in businesses which the Advisors judged to be analogous to the Company's were acquired within the last three years. Specifically, the Advisors reviewed the following transactions (indicated as target/acquiror): CEM Corporation/Investor Group, Hach Co./Danaher Corp., PerkinElmer-Instrument Division/EG&G Inc., Drexelbrook Engineering Co./Ametek Inc. and BIE Technologies Inc./Shareholders. The Advisors applied a range of multiples derived from such analysis to the Company's estimated (based upon the 2000 Projections) sales, 20 21 EBITDA, EBIT and net income for fiscal 1999, and arrived at an estimated range of equity values for the Shares of between $7.00 and $8.50 per Share. No company or transaction used in the comparable public trading multiple analysis or the selected transaction analysis is identical to the Company or the Offer and the Merger. Accordingly, an analysis of the results of the foregoing necessarily involves complex considerations and judgments concerning differences in financial and operating characteristics of the Company and other factors that could affect the public trading value of the companies to which they are being compared. In evaluating the comparable companies, the Advisors made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of the Company. Discounted Cash Flow Analysis. The Advisors conducted a discounted cash flow analysis for the purpose of determining the fully diluted equity value per Share. The Advisors calculated the unlevered free cash flows that the Company is expected to generate during fiscal years 2000 through 2004 based upon financial projections prepared by the Advisors after discussions with the management of Thermedics and Thermo Electron. The Advisors also calculated a range of terminal asset values of the Company at the end of the 5-year period ending 2004 by applying a perpetual growth rate ranging from 0.5% to 1.5% to the unlevered free cash flow of the Company during the final year of the 5-year period. The unlevered free cash flows and the range of terminal asset values were then discounted to present values using a range of discount rates from 9.5% to 10.5%, which were chosen by the Advisors based upon an analysis of the Company's weighted average cost of capital. The present value of the unlevered free cash flows and the range of terminal asset values were then adjusted for the Company's estimated 1999 fiscal year-end excess cash, option exercise proceeds and total debt. Based on this analysis, the Advisors calculated an estimated range of equity values of between $7.00 and $8.25 per Share. Historical Common Stock Performance. The Advisors conducted a historical analysis of the closing price of the Shares over the 52-week period prior to the date of their Opinion and also reviewed the closing price of the Shares as of the date two weeks prior to the date of their Opinion. During the 52-week period, based on trading prices on the American Stock Exchange, the Company's Shares achieved a high trading price of $10.875 on May 24, 1999 and a low trading price of $6.75 on December 31, 1999. On January 11, 2000, the closing price of the Shares was $7.3125 and on January 25, 2000 the closing price of the Shares was $7.9375. The summary set forth above does not purport to be, and is not, a complete description of the financial analyses or data undertaken or presented by the Advisors. The summary of the Advisors' Opinion set forth in this Offer to Purchase is qualified in its entirety by reference to the full text of the written Opinion. The full text of the Advisors' written Opinion, which sets forth among other things the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by J.P. Morgan and The Beacon Group in conducting their financial analysis and in rendering their Opinion, is attached as Exhibit 12(c) to the Schedule TO. The written Opinion should be read carefully and in its entirety. A copy of the Advisors' written Opinion will be made available for inspection and copying at the principal office of Thermo Electron during its regular business hours upon request from any record holder of the Shares or a representative of such person designated as such in writing or may be obtained from the Schedule TO filed with the Commission. Requests to have the Opinion made available should be directed to the Corporate Secretary of Thermo Electron at the address set forth under "Certain Information Concerning The Purchaser, Corpak, Thermedics And Thermo Electron." The preparation of the financial analysis and the related fairness Opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. In arriving at their Opinion, the Advisors considered the results of all of their analyses as a whole and did not attribute any particular weight to any analysis or factor considered by them. The Advisors believe that the summary set forth above and their analyses must be considered as a whole and that selecting portions thereof, without considering all of their analyses, could create an incomplete view of the processes underlying their analyses and Opinion. In addition, the Advisors may have given various analyses and factors more or less weight than other analyses and factors, 21 22 and may have deemed various assumptions more or less probable than other assumptions so that the ranges of valuation resulting from any particular financial analysis described should not be taken as the Advisors' view of the actual value of the Company. The Advisors based their analyses on assumptions that they deemed reasonable, including assumptions concerning general business and economic conditions and industry-specific factors. The other principal assumptions upon which the Advisors based their analyses are set forth above under the description of each such analysis. The Advisors' analyses are not necessarily indicative of actual values or actual future results that might be achieved, which values may be higher or lower than those indicated. Moreover, the Advisors' analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be bought or sold. As described above, the Advisors' financial analysis and Opinion was only one of many factors considered by the Boards of Directors of Thermedics and Thermo Electron in their determination that the terms of the Offer and the Merger are fair to the Public Stockholders and should not be viewed as determinative of the views of the Boards of Directors of Thermedics and Thermo Electron with respect to the value of the Company. J.P. Morgan and The Beacon Group advised the Boards of Directors of Thermo Electron and Thermedics in connection with the Offer and the Merger in part because the Advisors had been retained to advise Thermo Electron in connection with the overall reorganization of Thermo Electron and its subsidiaries. The Boards of Directors of Thermo Electron and Thermedics also considered J.P. Morgan's and The Beacon Group's experience and expertise. J.P. Morgan is an international corporate and investment bank, and The Beacon Group is a nationally recognized private investment banking firm. As part of their investment banking businesses, J.P. Morgan and The Beacon Group are regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. J.P. Morgan has advised Thermo Electron and Thermedics that, in the ordinary course of its business, it or its affiliates may actively trade the debt and/or equity securities of the Company, Thermedics, Thermo Electron and their affiliates for their own account and for the accounts of customers and, accordingly, may at any time hold a long or short term position in such securities. In October 1999, Thermo Electron engaged The Beacon Group as its financial advisor in connection with Thermo Electron's proposed acquisition of the outstanding shares held by public stockholders in certain subsidiaries. Thermo Electron paid The Beacon Group $500,000 in fees for services rendered pursuant to that engagement in connection with the acquisition of the outstanding publicly-held shares of common stock of ThermoTrex Corporation and ThermoLase Corporation. As noted above, J.P. Morgan and The Beacon Group have acted as financial advisors to Thermo Electron for the purpose of advising Thermo Electron in connection with its strategic alternatives, including the proposed reorganization of Thermo Electron and its subsidiaries. As part of the proposed reorganization, it is contemplated that Thermo Electron will acquire the publicly-held minority interest in Thermedics and that J.P. Morgan and The Beacon Group will act as financial advisors to Thermo Electron in connection with such acquisition. Pursuant to a letter agreement among Thermo Electron and J.P. Morgan and The Beacon Group dated January 17, 2000, Thermo Electron has agreed to pay each of J.P. Morgan and The Beacon Group a fee of $500,000 for its services in connection with the Offer and the Merger. In addition, J.P. Morgan and The Beacon Group will be reimbursed for expenses incurred in connection with these transactions. The letter agreement also relates to the overall proposed reorganization of Thermo Electron and provides for separate fees for services with respect to other elements of Thermo Electron's reorganization. These other fees include a minimum retainer for each of J.P. Morgan and The Beacon Group of $1.25 million, and the engagement letter provides for substantial additional compensation if some or all of the other elements of Thermo Electron's reorganization are completed. Thermo Electron has agreed to indemnify J.P. Morgan and The Beacon Group and their affiliates against certain liabilities, including liabilities under the federal securities laws, in connection with their engagement. 22 23 CERTAIN PROJECTED FINANCIAL DATA The Company does not, as a matter of course, make public forecasts or projections as to future sales, earnings or other income statement data, cash flows or balance sheet and financial position information. However, Thermedics and Thermo Electron had access to the 1999-2000 Projections and the 2000 Projections, made the 1999-2000 Projections available to the Special Committee and made the 2000 Projections available to the Advisors. The 1999-2000 Projections and the 2000 Projections were prepared by the Company's management in the regular course of its financial planning. The 2001-2003 Projections were prepared by Thermo Electron, with the assistance of the Company's management, for the sole purpose of preparing the discounted cash flow analysis included in the August 30 Offer. The 1999-2000 Projections, the 2000 Projections and the 2001-2003 Projections are collectively referred to herein as the "Projections". The following summaries of the 1999-2000 Projections and the 2000 Projections are included in this Offer to Purchase solely because the 1999-2000 Projections were made available to Thermedics, Thermo Electron and the Special Committee, and the 2000 Projections were made available to Thermedics, Thermo Electron and the Advisors. The 2001-2003 Projections are included in this Offer to Purchase because they were provided to the Special Committee. The Projections do not reflect any of the effects of the Offer, the Merger or other changes that may in the future be deemed appropriate concerning the Company and its assets, business, operations, properties, policies, corporate structure, capitalization and management in light of the circumstances then existing. Thermedics and Thermo Electron believe that the assumptions upon which the Projections are based were reasonable at the time the Projections were prepared, given the information known by management of the Company or Thermo Electron at such time. The Projections were not prepared with a view toward public disclosure or compliance with published guidelines of the Commission or the American Institute of Certified Public Accountants regarding forward-looking information or generally accepted accounting principles. Neither the Company's independent auditors, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the prospective financial information contained in the Projections nor have they expressed any opinion or given any form of assurance on such information or its achievability, and they assume no responsibility for, and disclaim any association with, such prospective financial information. Furthermore, the Projections necessarily make numerous assumptions, many of which are beyond the control of Thermedics and Thermo Electron and may prove not to have been, or may no longer be, accurate. Additionally, this information, except as otherwise indicated, does not reflect revised prospects for the Company's businesses, changes in general business and economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time such information was prepared. Accordingly, such information is not necessarily indicative of current values or future performance, which may be significantly more favorable or less favorable than as set forth below, and should not be regarded as a representation that they will be achieved. THE PROJECTIONS ARE NOT GUARANTEES OF PERFORMANCE. THEY INVOLVE RISKS, UNCERTAINTIES AND ASSUMPTIONS. THE FUTURE FINANCIAL RESULTS AND STOCKHOLDER VALUE OF THE COMPANY MAY MATERIALLY DIFFER FROM THOSE EXPRESSED IN THE PROJECTIONS. MANY OF THE FACTORS THAT WILL DETERMINE THESE RESULTS AND VALUES ARE BEYOND THE COMPANY'S ABILITY TO CONTROL OR PREDICT. STOCKHOLDERS ARE CAUTIONED NOT TO PLACE UNDUE RELIANCE ON THE PROJECTIONS. THERE CAN BE NO ASSURANCE THAT THE PROJECTIONS WILL BE REALIZED OR THAT THE COMPANY'S FUTURE FINANCIAL RESULTS WILL NOT MATERIALLY VARY FROM THE PROJECTIONS. THE COMPANY DOES NOT INTEND TO UPDATE OR REVISE THE PROJECTIONS. 23 24 The following are the 1999-2000 Projections: 1999-2000 PROJECTIONS (IN THOUSANDS) PROJECTED Q3 PROJECTED Q4 PROJECTED PROJECTED 1999 1999 1999 2000 SELECTED INCOME STATEMENT DATA: Revenues.............................................. $17,768 $17,769 $74,136 $74,508 ------- ------- ------- ------- Costs and Operating Expenses: Cost of revenues.................................... 8,065 8,065 32,951 33,082 Operating expenses.................................. 7,463 7,431 31,926 30,699 ------- ------- ------- ------- 15,528 15,496 64,877 63,781 ------- ------- ------- ------- Operating Income...................................... 2,240 2,273 9,259 10,727 Interest Income....................................... 300 300 1,280 1,200 Other Expense, Net.................................... -- -- (18) -- ------- ------- ------- ------- Income Before Provision for Income Taxes.............. 2,540 2,573 10,521 11,927 Provision for Income Taxes............................ 991 1,004 4,104 4,651 ------- ------- ------- ------- Net Income............................................ $ 1,549 $ 1,569 $ 6,417 $ 7,276 ======= ======= ======= ======= SELECTED BALANCE SHEET DATA: Accounts Receivable, Net.............................. $15,400 $15,300 $15,725 $14,600 Inventories........................................... 16,350 16,100 16,476 15,200 Prepaid Income Taxes and Other Current Assets......... 5,533 5,564 5,633 5,564 ------- ------- ------- ------- Total Current Assets Excluding Cash and Investments... 37,283 36,964 37,834 35,364 Property, Plant, and Equipment: Balance, beginning of period........................ 4,834 4,784 4,939 4,734 Additions........................................... 425 425 1,782 1,650 Depreciation expense................................

The financial interests of Thermo Electron and Thermedics are adverse as to the Offer Price to the financial interests of the Public Stockholders. DIRECTORS OF THERMO ELECTRON AND THERMEDICS. The members of the Boards of Directors of Thermo Electron and Thermedics own common stock of, or hold options to purchase the common stock of, Thermo Electron, Thermedics and/or the Company. In addition, certain members of the Boards of Directors of Thermo Electron and Thermedics are also officers of the Company. These positions and equity interests present these directors with actual or potential conflicts of interest in determining the fairness of the Offer and the Merger to the Public Stockholders. See Schedule I to this Offer to Purchase for a listing of the positions that the members of the Boards of Directors of Thermo Electron and Thermedics hold with Thermo Electron, Thermedics and the Company and their ownership of the common stock of Thermo Electron, Thermedics and the Company. To the knowledge of each of the Purchaser, Corpak, Thermedics and Thermo Electron, all of the directors and executive officers of Thermo Electron and Thermedics who own Shares have advised Thermedics that they intend to tender their Shares in the Offer. EXECUTIVE OFFICERS AND DIRECTORS OF THE COMPANY. In considering any position that the Board of Directors of the Company may take with respect to the Offer, the Public Stockholders should be aware that the executive officers and certain directors of the Company have interests in connection with the Offer and the Merger that present them with actual or potential conflicts of interest, as summarized below. Following consummation of the Offer and the Merger, Thermedics anticipates that the board of directors of the Purchaser, as the corporation surviving the Merger (the "Surviving Corporation"), will be comprised solely of members of the Company's and Thermedics' management. Officers and directors of the Company who own Shares will receive the Offer Price in the Offer or the Merger on the same terms as the Public Stockholders. As of January 28, 2000, the members of the Board of Directors and executive officers of the Company owned in the aggregate 18,103 Shares and will receive a payment for their Shares in the aggregate amount of $144,824, assuming that they tender all of their Shares in the Offer or their Shares are acquired in the Merger. To the knowledge of each of the Purchaser, Corpak, Thermedics and Thermo Electron, all of the directors and executive officers of the Company who own Shares have advised Thermedics that they intend to tender their Shares in the Offer. 26 27 In addition, as of January 28, 2000, such Board members and executive officers of the Company held Options to acquire an aggregate of 252,800 Shares, with exercise prices ranging from $7.56 to $11.99 per Share. Unvested Options held by such persons will be assumed by Thermo Electron in the Merger and converted into options to acquire shares of Thermo Electron's common stock on the same terms as are applicable to all the other holders of Options. In the case of vested Options held by such persons, the holders will be given the opportunity to elect in the Merger either to convert the Options into options for Thermo Electron common stock or to receive cash for their Options at the Offer Price less the applicable exercise price. See "--Certain Effects Of The Offer And The Merger--Assumption of Options by Thermo Electron." Certain members of the Board of Directors of the Company and certain executive officers of the Company are directors or officers of Thermo Electron and/or Thermedics. All of such directors and executive officers of the Company hold equity interests in Thermo Electron and Thermedics. Mr. Melas-Kyriazi, the chief financial officer of the Company, is also the chief financial officer of Thermo Electron and Thermedics. Mr. John T. Keiser, a director of the Company, is chief operating officer, biomedical of Thermo Electron and is president and chief executive officer of Thermedics. Mr. Earl R. Lewis, a director of the Company, is chief operating officer, measurement and detection, of Thermo Electron. Mr. Paul F. Kelleher, the chief accounting officer of the Company, is also the chief accounting officer of Thermo Electron and Thermedics. Consequently, certain of these directors and officers receive or have received compensation not only from the Company but also from Thermo Electron, Thermedics and/or their affiliates. INDEMNIFICATION AGREEMENTS. Thermo Electron has entered into separate indemnification agreements with each of the Company's executive officers and directors providing for indemnification of and advancement of expenses to such persons directly by Thermo Electron in the event that such person, by reason of his or her status as a director or officer of the Company (or service as a director, officer or fiduciary of another enterprise at the request of Thermo Electron), is made or threatened to be made a party to any threatened, pending, or completed action, suit or other proceeding, whether civil, criminal, administrative or investigative, if the indemnitee acted in good faith and in a manner the indemnitee reasonably believed to be in or not opposed to the best interests of Thermo Electron, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. In the case of any threatened, pending or completed action, suit or proceeding by or in the right of Thermo Electron, indemnification shall be made to the maximum extent permitted under Delaware law. OTHER POSSIBLE PURCHASES OF SHARES If the Offer is successfully completed, Thermo Electron and its subsidiaries will collectively own at least 90% of the outstanding Shares. If, after the Offer is completed but prior to the effective date of the Merger (the "Effective Date of the Merger"), as a result of the exercise of Options or for any other reason, Thermo Electron and its subsidiaries collectively own less than 90% of the outstanding Shares, the Purchaser intends to acquire additional Shares in the open market or in privately negotiated transactions to the extent required for Thermo Electron and its subsidiaries' collective ownership of Shares to equal or exceed 90%. If the Offer is not completed, the Purchaser may make open market or privately negotiated purchases of Shares to the extent necessary in order for Thermo Electron and its subsidiaries collectively to own at least 90% of the outstanding Shares. Such open market or privately negotiated purchases would be made at market prices or privately negotiated prices at the time of purchase, which may be higher or lower than the Offer Price. THE MERGER If the Offer is successfully completed, Corpak and Thermo Electron plan to contribute the Shares they own to the Purchaser in exchange for capital stock of the Purchaser and to cause the Company to merge into the Purchaser in a short-form merger. The short-form merger would occur as soon as possible after completion of the Offer. In the Merger, the Purchaser would be the surviving corporation and would change its name to "Thermedics Detection Inc." The surviving corporation would be owned exclusively by Thermo Electron and Corpak. Under Massachusetts law, if the Purchaser owns at least 90% of the outstanding Shares, the Purchaser would have the power to approve, adopt and consummate the Merger without a vote of the Company's stockholders (other than the Purchaser) or Board of Directors. 27 28 On the Effective Date of the Merger, each outstanding Share (other than Shares held by stockholders, if any, who are entitled to and perfect their appraisal rights under Massachusetts law) would be cancelled and converted into the right to receive the Offer Price in cash, without interest. After the Merger, Thermedics and Thermo Electron will, directly or indirectly, own 100% of the equity interest in the Surviving Corporation. CERTAIN EFFECTS OF THE OFFER AND THE MERGER GENERAL. Upon completion of the Offer and the Merger, Thermedics and Thermo Electron would have complete control over the conduct of the Company's business and together would have a 100% interest in the net book value and net earnings of the Company. In addition, Thermedics and Thermo Electron would receive the benefit of complete control over any future increases in the value of the Company and would bear the complete risk of any losses incurred in the operation of the Company and any decrease in the value of the Company. Thermo Electron's and its subsidiaries' aggregate ownership of the Company prior to the transactions contemplated by the Offer and the Merger was approximately 88.9%. Upon completion of the Offer and the Merger, Thermo Electron's and its subsidiaries' aggregate interest in the Company's net book value of approximately $121.7 million on January 1, 2000 and net earnings of $5.1 million for the year ended January 1, 2000 would increase from approximately 88.9% of such amounts to 100% of such amounts. BENEFITS AND DETRIMENTS TO THE PUBLIC STOCKHOLDERS. Upon completion of the Offer and the Merger, the Public Stockholders would no longer have any interest in, and would not be stockholders of, the Company and therefore would not participate in the Company's future earnings and potential growth and would no longer bear the risk of any decreases in the value of the Company. In addition, the Public Stockholders would not share in any distribution of proceeds after any sales of businesses of the Company, whether contemplated at the time of the Offer or thereafter. See "--Conduct Of The Company's Business After The Offer And The Merger." All of the Public Stockholders' other incidents of stock ownership, such as the rights to vote on certain corporate decisions, to elect directors, to receive distributions upon the liquidation of the Company and to receive appraisal rights upon certain mergers or consolidations of the Company (unless such appraisal rights are perfected in connection with the Merger), as well as the benefit of potential increases in the value of their holdings in the Company based on any improvements in the Company's future performance, would be extinguished upon acceptance of Shares tendered in the Offer or, if not tendered, upon completion of the Merger. Upon completion of the Offer and the Merger, the Public Stockholders would also not bear the risks of potential decreases in the value of their holdings in the Company based on any downturns in the Company's future performance. Instead, the Public Stockholders would have immediate liquidity in the form of the Offer Price in place of an ongoing equity interest in the Company in the form of the Shares. In summary, if the Offer and the Merger are completed, the Public Stockholders would have no ongoing rights as stockholders of the Company (other than statutory appraisal rights in the case of Public Stockholders who are entitled to and perfect such rights under Massachusetts law). POSSIBLE EFFECT OF THE OFFER AND OPEN MARKET PURCHASES ON THE MARKET FOR SHARES. Following the completion of the Offer and prior to the Effective Date of the Merger, the purchase of Shares by the Purchaser pursuant to the Offer or any subsequent open market or privately negotiated purchases would reduce the number of Shares that might otherwise trade publicly and may reduce the number of holders of Shares. This could adversely affect the liquidity and market value of the remaining Shares held by the public. AMERICAN STOCK EXCHANGE LISTING. If the Offer and Merger are consummated, the Shares would not meet the requirements for continued listing on the American Stock Exchange and would be delisted. Assuming that the Merger occurs shortly after the completion of the Offer, Thermo Electron and Thermedics do not expect the American Stock Exchange to delist the Shares until after the Effective Date of the Merger. Following the closing of the Offer and prior to the Effective Date of the Merger, depending upon the aggregate market value and the number of Shares not purchased pursuant to the Offer or any subsequent open market or privately negotiated purchases, as well as the number of Public Stockholders who are not affiliated with Thermedics or Thermo Electron, the Shares may no longer meet the quantitative requirements for continued listing on the American Stock Exchange. The listing requirements of the American Stock Exchange 28 29 require that an issuer have at least 200,000 publicly held shares, held by at least 300 stockholders, with a market value of at least $1,000,000 and have stockholders' equity of at least $2,000,000 or $4,000,000 (depending on profitability levels during the issuer's four most recent fiscal years). In the event that the Shares no longer meet the requirements for listing on the American Stock Exchange, it is possible that the Shares would continue to trade in the over-the-counter market prior to the Effective Date of the Merger and that price or other quotations might still be available from other sources. The extent of the public market for the Shares and the availability of such quotations would, however, depend upon such factors as the number of holders and/or the aggregate market value of such Shares remaining at such time, the interest in maintaining a market in such Shares on the part of securities firms, the possible termination of registration of such Shares under the Exchange Act, as described below, and other factors. The Purchaser cannot predict whether a reduction in the number of Shares that might otherwise trade publicly would have an adverse or beneficial effect on the market price for or marketability of the Shares or whether it would cause future market prices to be greater or less than the price paid in the Offer and the Merger. EXCHANGE ACT REGISTRATION. The Shares are currently registered under the Exchange Act. If the Offer and the Merger are completed, however, the Company's reporting obligations under the Exchange Act would terminate. Prior to the Effective Date of the Merger, the purchase of Shares pursuant to the Offer or open market or privately negotiated purchases following consummation of the Offer may result in the Shares becoming eligible for deregistration under the Exchange Act. Registration of the Shares may be terminated upon application by the Company to the Commission if the Shares are not listed on a national securities exchange (see "--American Stock Exchange Listing") and there are fewer than 300 record holders of the Shares. Thermedics presently intends to seek to cause the Company to terminate the registration of the Shares under the Exchange Act as soon after the consummation of the Offer or the Merger as the requirements for termination of registration are met. The termination of the registration of the Shares under the Exchange Act would substantially reduce the information required to be furnished by the Company to holders of the Shares and would make certain provisions of the Exchange Act, such as the short-swing profit recovery provisions of Section 16(b), the requirement of furnishing a proxy statement in connection with stockholders' meetings pursuant to Section 14(a) and the requirements of Rule 13e-3 under the Exchange Act with respect to "going private" transactions, no longer applicable to the Shares. Furthermore, "affiliates" of the Company and persons holding "restricted securities" of the Company may be deprived of the ability to dispose of the securities pursuant to Rule 144 under the Securities Act. If registration of the Shares under the Exchange Act were terminated, the Shares would no longer be "margin securities" or eligible for listing on the American Stock Exchange. MARGIN REGULATIONS. The Shares are currently "margin securities" under the rules of the Board of Governors of the Federal Reserve System (the "Federal Reserve Board"), which has the effect, among other things, of allowing brokers to extend credit on the collateral of such Shares for the purpose of buying, carrying or trading in securities ("purpose loans"). If the Offer and the Merger are completed, the Shares would no longer be "margin securities." Following the purchase of Shares pursuant to the Offer or any subsequent open market or privately negotiated purchases and prior to the Effective Date of the Merger, depending upon factors such as the number of record holders of the Shares and the number and market value of publicly held Shares, the Shares might no longer constitute "margin securities" for purposes of the Federal Reserve Board's margin regulations and therefore no longer be used as collateral for purpose loans made by brokers. In addition, if registration of the Shares under the Exchange Act were terminated, the Shares would no longer constitute "margin securities." TREATMENT OF THERMEDICS DETECTION OPTIONS. The Company has, from time to time, issued Options to acquire Shares pursuant to the Company's Equity Incentive Plan and Employees Equity Incentive Plan (together, the "Plans"). On the Effective Date of the Merger, each outstanding unvested Option under the Company's Plans will be assumed by Thermo Electron and converted into options to acquire shares of Thermo Electron common stock as provided below. In the case of vested Options, the holders will be given the opportunity to elect in the Merger either to convert the Options into vested options for Thermo Electron common stock or to receive cash from Thermedics in an amount equal to the number of Shares that have 29 30 vested under such Option multiplied by the difference between the Offer Price and the exercise price per Share of such Option. Each Option assumed by Thermo Electron will continue to have, and be subject to, the same terms and conditions, including the vesting of shares issuable upon the exercise thereof, as were applicable to the Option immediately prior to the Effective Date of the Merger, except that: - each Option will be exercisable (or will become exercisable in accordance with its terms) for that number of whole shares of Thermo Electron common stock equal to the product of the number of Shares that were issuable upon exercise of such Option immediately prior to the Effective Date of the Merger multiplied by the Exchange Ratio (as defined below), rounded down to the nearest whole number of shares of Thermo Electron common stock, and - the per share exercise price for the shares of Thermo Electron common stock issuable upon exercise of such assumed Option will be equal to the quotient determined by dividing the exercise price per Share at which such Option was exercisable immediately prior to the Effective Date of the Merger by the Exchange Ratio, rounded up to the nearest whole cent. The "Exchange Ratio" is a fraction, the numerator of which is the Offer Price and the denominator of which is the closing price of the Thermo Electron common stock on the day immediately preceding the Effective Date of the Merger as reported on the consolidated transactions tape. ACCOUNTING TREATMENT. The Offer and the Merger would be accounted for as the acquisition of a minority interest by Thermedics, using the purchase method of accounting. TAX CONSEQUENCES. For federal income tax purposes, the receipt of the cash consideration by holders of the Shares pursuant to the Offer or the Merger will be a taxable sale of the holder's Shares. See "Certain Federal Income Tax Consequences." CONDUCT OF THE COMPANY'S BUSINESS AFTER THE OFFER AND THE MERGER Following Thermo Electron's reorganization, Thermo Electron plans to retain the Surviving Corporation as part of Thermo Electron's core measurement and detection instruments businesses. In connection with the reorganization of Thermo Electron and its subsidiaries, Thermo Electron intends to evaluate ways in which its instruments businesses, including the Company's business, can be more efficiently integrated and operated. Thermedics and Thermo Electron do not currently have any commitment or agreement for the sales of any of the Company's businesses. Additionally, Thermo Electron and Thermedics do not currently contemplate any material change in the composition of the Company's current management, except that Thermedics intends to appoint a Board of Directors of the Surviving Corporation comprised solely of members of the Company's and Thermedics' management after the Merger. In connection with its reorganization, Thermo Electron currently intends to acquire all of the outstanding common stock of Thermedics that it does not currently own. If such transaction is completed, the Surviving Corporation will become an indirect wholly-owned subsidiary of Thermo Electron. Except as otherwise described in this Offer to Purchase, the Purchaser, Corpak, Thermedics and Thermo Electron do not have, as of the date of this Offer to Purchase, any specific plans or proposals for: - any extraordinary corporate transaction involving the Company after the completion of the Offer and the Merger; - any sale or transfer of a material amount of assets currently held by the Company after the completion of the Offer and the Merger; - any change in the Board of Directors or management of the Company; - any material change in the Company's dividend rate or policy; or - any other material change in the Company's corporate structure or business. 30 31 CONDUCT OF THE COMPANY'S BUSINESS IF THE OFFER IS NOT COMPLETED If the Offer is not completed because the Minimum Condition or another condition is not satisfied or waived, Thermo Electron and Thermedics expect that the Company's current management will continue to operate the Company's business substantially as presently operated. See "--Conduct Of The Company's Business After The Offer And The Merger." However, Thermedics and Thermo Electron anticipate that if the Offer is not completed, Thermedics and Thermo Electron will re-evaluate the role of the Company within the overall reorganization strategy being pursued by Thermo Electron. In particular, Thermedics and Thermo Electron may consider: - engaging in open market or privately negotiated purchases of Shares to increase Thermo Electron's and its subsidiaries' aggregate ownership of Shares to at least 90% of the outstanding Shares and then effecting a short-form merger; - proposing that the Purchaser and the Company enter into a long-form merger agreement, which would require the approval of the Company's Board of Directors, and voting all of their Shares in favor of such merger; - keeping outstanding the public minority interest in the Company, in which case the Public Stockholders would receive no cash for their Shares and would bear the risk that the trading price per Share could decrease to a price that is less than the Offer Price; or - selling their interests in the Company or pursuing a sale of the entire Company to a third party. If Thermedics and Thermo Electron were to pursue any of these alternatives, it may take considerably longer for the Public Stockholders to receive any consideration for their Shares (other than through sales in the open market) than if they had tendered their Shares in the Offer. Any such transaction may result in proceeds per Share to the Public Stockholders that are more or less than the Offer Price. 31 32 THE TENDER OFFER TERMS OF THE OFFER; EXPIRATION DATE Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment), the Purchaser will accept for payment and pay for all Shares validly tendered prior to the Expiration Date (as defined below) and not properly withdrawn as provided in "--Withdrawal Rights." The term "Expiration Date" means 12:00 midnight, New York City time, on Thursday, April 6, 2000, unless and until the Purchaser, in its sole discretion, shall have extended the period during which the Offer is open, in which event the term "Expiration Date" shall mean the latest time and date at which the Offer, as so extended by the Purchaser, shall expire. Subject to the applicable rules and regulations of the Commission, the Purchaser expressly reserves the right, in its sole discretion, at any time and from time to time, to extend the period during which the Offer is open for any reason, including the failure to satisfy any of the conditions specified in "--Certain Conditions Of The Offer," and thereby delay acceptance for payment of, and payment for, any Shares, by giving oral or written notice of such extension to the Depositary. There can be no assurance that the Purchaser will exercise its right to extend the Offer. During any such extension, all Shares previously tendered and not properly withdrawn will remain subject to the Offer, subject to the rights of a tendering stockholder to withdraw such stockholder's Shares. See "--Withdrawal Rights." Subject to the applicable rules and regulations of the Commission, the Purchaser also expressly reserves the right, in its sole discretion, at any time and from time to time, to (1) terminate the Offer and not accept for payment (or pay for) any Shares if any of the conditions referred to in "--Certain Conditions Of The Offer" has not been satisfied or upon the occurrence and during the continuance of any of the events specified in "--Certain Conditions Of The Offer," and (2) waive any condition or amend the Offer in any respect, in each case by giving oral or written notice of termination, waiver or amendment to the Depositary and by making a public announcement thereof. The Purchaser acknowledges (a) that Rule 14e-1(c) under the Exchange Act requires the Purchaser to pay the consideration offered or return the Shares tendered promptly after the termination or withdrawal of the Offer and (b) that the Purchaser may not delay acceptance for payment of, or payment for, any Shares upon the occurrence of any of the conditions specified in "--Certain Conditions Of The Offer" without extending the period during which the Offer is open. If the Minimum Condition or any other condition specified in "--Certain Conditions Of The Offer" is not fulfilled by the Expiration Date, the Purchaser reserves the right (but shall not be obligated) to (1) decline to purchase any of the Shares tendered, return all tendered Shares to tendering stockholders and terminate the Offer, (2) extend the Offer and retain all tendered Shares until the expiration of the Offer, as extended, subject to the terms and conditions of the Offer (including any rights of stockholders to withdraw their Shares), or (3) waive or reduce the condition and, subject to complying with applicable rules and regulations of the Commission, accept for payment and purchase all Shares validly tendered. Any extension, termination or amendment will be followed as promptly as practicable by a public announcement thereof, such announcement, in the case of an extension, to be made no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date. Without limiting the manner in which the Purchaser may choose to make any public announcement, except as provided by applicable law (including Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act, which require that material changes be promptly disseminated to holders of Shares), the Purchaser will have no obligation to publish, advertise or otherwise communicate any such public announcement other than by issuing a release to the Dow Jones News Service. If the Purchaser makes a material change in the terms of the Offer or the information concerning the Offer, or waives a material condition of the Offer, the Purchaser will disseminate additional tender offer materials (including by public announcement as set forth above) and extend the Offer to the extent required by Rules 14d-4(d), 14d-6(d) and 14e-1 under the Exchange Act. The minimum period during which the Offer must remain open following material changes in the terms of the Offer or information concerning the Offer, other than a change in price, a change in percentage of securities sought or a change in any dealer's 32 33 soliciting fee, will depend upon the facts and circumstances, including the relative materiality of the changes. With respect to a change in price or, subject to certain limitations, a change in the percentage of securities sought or a change in any dealer's soliciting fee, a minimum ten business day period from the date of such change is generally required to allow for adequate dissemination of such change to stockholders. Accordingly, if, prior to the Expiration Date, the Purchaser decreases the number of Shares being sought, increases the consideration offered pursuant to the Offer or adds a dealer's soliciting fee, and if the Offer is scheduled to expire at any time earlier than the period ending on the tenth business day from the date that notice of such increase, decrease or addition is first published, sent or given to stockholders, the Offer will be extended at least until the expiration of such ten business day period. For purposes of the Offer, a "business day" means any day other than a Saturday, Sunday or a federal holiday and consists of the time period from 12:01 a.m. through 12:00 midnight, New York City time. The Company has provided the Purchaser with the Company's stockholder list and security position listings for the purpose of disseminating the Offer to holders of Shares. This Offer to Purchase and the related Letter of Transmittal and, if required, other relevant material will be mailed to record holders of Shares and will be furnished to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the Company's stockholder list or, if applicable, who are listed as participants in a clearing agency's security position listing for subsequent transmittal to beneficial owners of Shares. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES Upon the terms and subject to the conditions of the Offer (including, if the Offer is extended or amended, the terms and conditions of any such extension or amendment), the Purchaser will purchase by accepting for payment, and will pay for, all Shares validly tendered prior to the Expiration Date and not properly withdrawn (including Shares validly tendered and not withdrawn during any extension of the Offer, if the Offer is extended, subject to the terms and conditions of such extension), promptly after the Expiration Date. In addition, subject to complying with Rule 14e-1 under the Exchange Act, the Purchaser expressly reserves the right, in its sole discretion, to delay the acceptance for payment of, or payment for, Shares in order to comply, in whole or in part, with any applicable law. In all cases, payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of: - certificates evidencing Shares ("Share Certificates") or timely confirmation of a book-entry transfer of such Shares ("Book-Entry Confirmation") into the Depositary's account at The Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the procedures set forth in "--Procedures For Accepting The Offer And Tendering Shares"; - the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, with any required signature guarantees, or an Agent's Message (as defined below) in connection with a book-entry transfer; and - any other documents required by the Letter of Transmittal. Accordingly, payment may be made to tendering stockholders at different times if delivery of the Shares and other required documents occurs at different times. The term "Agent's Message" means a message transmitted by the Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has received an express acknowledgment from the participant in the Book-Entry Transfer Facility tendering the Shares which are the subject of such Book-Entry Confirmation, that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that the Purchaser may enforce such agreement against such participant. For purposes of the Offer, the Purchaser will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered and not properly withdrawn if, as and when the Purchaser gives oral or 33 34 written notice to the Depositary of the Purchaser's acceptance for payment of such Shares pursuant to the Offer. Upon the terms and subject to the conditions of the Offer, payment for Shares so accepted for payment pursuant to the Offer will be made by deposit of the aggregate purchase price therefor with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payment from the Purchaser and transmitting such payment to stockholders whose Shares have been accepted for payment. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE FOR SHARES BE PAID, REGARDLESS OF ANY EXTENSION OF THE OFFER OR DELAY IN MAKING SUCH PAYMENT. Upon the deposit of funds with the Depositary for the purpose of making payment to validly tendering stockholders, the Purchaser's obligation to make such payment shall be satisfied and such tendering stockholders must thereafter look solely to the Depositary for payment of the amounts owed to them by reason of the acceptance for payment of Shares pursuant to the Offer. If any tendered Shares are not accepted for payment pursuant to the terms and conditions of the Offer for any reason, or if Share Certificates are submitted for more Shares than are tendered, Share Certificates representing Shares not purchased or not tendered will be returned, without expense, to the tendering stockholder (or, in the case of Shares tendered by book-entry transfer of such Shares into the Depositary's account at the Book-Entry Transfer Facility pursuant to the procedures for book-entry transfer set forth in "--Procedures For Accepting The Offer And Tendering Shares," such Shares will be credited to an account maintained at the Book-Entry Transfer Facility), as soon as practicable following expiration or termination of the Offer. If, prior to the Expiration Date, the Purchaser increases the consideration to be paid per Share, the Purchaser will pay such increased consideration for all Shares purchased pursuant to the Offer, whether or not such Shares have been tendered or purchased prior to such increase in consideration. The Purchaser reserves the right to transfer or assign, in whole or in part from time to time, to one or more of its affiliates, the right to purchase the Shares tendered pursuant to the Offer, but any such transfer or assignment will not relieve the Purchaser of its obligations under the Offer, nor will any such transfer or assignment in any way prejudice the rights of tendering stockholders to receive payment for Shares validly tendered and accepted for payment pursuant to the Offer. PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES GENERAL. Except as set forth below, in order for Shares to be validly tendered pursuant to the Offer, the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, together with any required signature guarantees, or an Agent's Message in connection with a book-entry delivery of Shares, and any other documents required by the Letter of Transmittal, must be received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase prior to the Expiration Date, and either (l) Share Certificates evidencing tendered Shares must be received by the Depositary at such address or such Shares must be tendered pursuant to the procedures for book-entry transfer set forth below (and a Book-Entry Confirmation must be received by the Depositary), in each case prior to the Expiration Date, or (2) the guaranteed delivery procedures set forth below must be complied with. No alternative, conditional or contingent tenders will be accepted and no fractional Shares will be purchased. All tendering stockholders, by execution of the Letter of Transmittal (or a facsimile thereof), waive any right to receive any notice of the acceptance of their Shares for payment. THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER FACILITY, IS AT THE SOLE OPTION AND RISK OF EACH TENDERING STOCKHOLDER AND, EXCEPT AS OTHERWISE PROVIDED UNDER THIS HEADING "--PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES," THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF DELIVERY IS MADE BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY. 34 35 BOOK-ENTRY TRANSFER. The Depositary will make a request to establish accounts with respect to the Shares at the Book-Entry Transfer Facility for purposes of the Offer within two business days after the date of this Offer to Purchase. Any financial institution that is a participant in the system of the Book-Entry Transfer Facility may make book-entry delivery of Shares by causing the Book-Entry Transfer Facility to transfer such Shares into the Depositary's account at the Book-Entry Transfer Facility in accordance with the Book-Entry Transfer Facility's procedures for such transfer. Although delivery of Shares may be effected through book-entry transfer into the Depositary's account at the Book-Entry Transfer Facility, the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, together with any required signature guarantees, or an Agent's Message, and any other documents required by the Letter of Transmittal, must, in any case, be received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase prior to the Expiration Date in order for such Shares to be validly tendered pursuant to the Offer, or the tendering stockholder must comply with the guaranteed delivery procedures described below. DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH THE BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY. SIGNATURE GUARANTEES. Signatures on all Letters of Transmittal must be guaranteed by a firm that is a bank, broker, dealer, credit union, savings association or other entity which is a member in good standing of the Securities Transfer Agents Medallion Program, the Stock Exchanges' Medallion Program or the New York Stock Exchange, Inc. Medallion Signature Program (an "Eligible Institution"), unless Shares tendered thereby are tendered (1) by a registered holder of Shares who has not completed either the box entitled "Special Delivery Instructions" or the box entitled "Special Payment Instructions" on the Letter of Transmittal or (2) for the account of an Eligible Institution. See Instruction 1 of the Letter of Transmittal. If the Share Certificates are registered in the name of a person other than the signer of the Letter of Transmittal, or if payment is to be made, or Share Certificates for unpurchased Shares are to be returned, to a person other than the registered holder(s), then the tendered Share Certificates must be endorsed or accompanied by appropriate stock powers signed exactly as the name(s) of the registered holder(s) appear(s) on the Share Certificates with the signature(s) on such Share Certificates or stock powers guaranteed by an Eligible Institution as provided above and in the Letter of Transmittal. See Instructions 1 and 5 of the Letter of Transmittal. GUARANTEED DELIVERY. If a stockholder desires to tender Shares pursuant to the Offer and such stockholder's Share Certificates are not immediately available or time will not permit all of the required documents to reach the Depositary prior to the Expiration Date, or the procedure for book-entry transfer cannot be completed on a timely basis, such Shares may nevertheless be tendered, provided that all of the following conditions are satisfied: - such tender is made by or through an Eligible Institution; - a properly completed and duly executed Notice of Guaranteed Delivery, substantially in the form provided by the Purchaser with the Letter of Transmittal, is received by the Depositary, in accordance with the procedure set forth as provided below, prior to the Expiration Date; and - the Share Certificates (or a Book-Entry Confirmation) for all tendered Shares, in proper form for transfer, in each case together with the Letter of Transmittal (or a facsimile thereof), properly completed and duly executed, with any required signature guarantees or, in the case of a book-entry transfer, an Agent's Message, and any other documents required by the Letter of Transmittal, are received by the Depositary within three American Stock Exchange trading days after the date of execution of such Notice of Guaranteed Delivery. The Notice of Guaranteed Delivery may be delivered by hand or transmitted by telegram, facsimile transmission or mail to the Depositary and must include a guarantee by an Eligible Institution in the form set forth in the Notice of Guaranteed Delivery. Notwithstanding any other provision of this Offer, payment for Shares accepted for payment pursuant to the Offer will in all cases be made only after timely receipt by the Depositary of Share Certificates therefor (or 35 36 Book-Entry Confirmation of the transfer of such Shares into the Depositary's account at the Book-Entry Transfer Facility), a properly completed and duly executed Letter of Transmittal (or a facsimile thereof), together with any required signature guarantees or, in the case of a book-entry transfer, an Agent's Message, and any other documents required by the Letter of Transmittal. Accordingly, payment may not be made to all tendering stockholders at the same time and will depend upon when Share Certificates or Book-Entry Confirmations of such Shares are received by the Depositary. BACKUP FEDERAL INCOME TAX WITHHOLDING. Under the U.S. federal income tax laws, the Depositary may, under certain circumstances, be required to withhold 31% of the amount of any payments made to certain stockholders pursuant to the Offer. To prevent such backup federal income tax withholding with respect to payments made to certain stockholders of the purchase price of Shares purchased pursuant to the Offer, each such stockholder must provide the Depositary with such stockholder's correct taxpayer identification number and certify that such stockholder is not subject to backup federal income tax withholding by completing the Substitute Form W-9 included in the Letter of Transmittal. See Instruction 9 of the Letter of Transmittal. APPOINTMENT AS PROXY. By executing the Letter of Transmittal, a tendering stockholder irrevocably appoints designees of the Purchaser as such stockholder's attorneys-in-fact and proxies in the manner set forth in the Letter of Transmittal, each with full power of substitution with respect to any Shares tendered thereby (and with respect to any and all other Shares or other securities issued or issuable in respect of such Shares on or after January 31, 2000). All such powers of attorney and proxies shall be considered irrevocable and coupled with an interest in the tendered Shares. Such appointment will be effective when, and only to the extent that, the Purchaser accepts the tendered Shares for payment and deposits the purchase price therefor with the Depositary. Upon such deposit, all prior powers of attorney and proxies given by such stockholder at any time with respect to such Shares (and other Shares and securities issued or issuable in respect of the tendered Shares on or after January 31, 2000) will, without further action, be revoked, and no subsequent powers of attorney or proxies may be given nor any subsequent written consents be executed by such stockholder (and, if given or executed, will not be deemed effective). Upon such deposit by the Purchaser, the designees of the Purchaser will, with respect to such Shares and other securities, be empowered to exercise all voting and other rights of such stockholder as they in their sole discretion may deem proper at any annual or special meeting of the Company's stockholders, or any adjournment or postponement thereof, or by written consent in lieu of any such meeting or otherwise. The Purchaser reserves the right to require that, in order for Shares to be deemed validly tendered, immediately upon the Purchaser's payment for such Shares, the Purchaser must be able to exercise full voting and other rights of a record and beneficial holder, including, without limitation, voting at any meeting of stockholders or by written consent in lieu of any such meeting. DETERMINATION OF VALIDITY. All questions as to the validity, form, eligibility (including the time of receipt) and acceptance for payment of any tendered Shares pursuant to any of the procedures described above will be determined by the Purchaser, in its sole discretion, which determination will be final and binding on all parties. The Purchaser reserves the absolute right to reject any and all tenders of any particular Shares determined by it not to be in appropriate form or for which the acceptance of or payment for may, in the opinion of its counsel, be unlawful. The Purchaser also reserves the absolute right to waive any of the conditions of the Offer or any defect or irregularities in the tender of any particular Shares, whether or not similar defects or irregularities are waived in the case of any other Shares. The Purchaser's interpretations of the terms and conditions of the Offer (including the Letter of Transmittal and Instructions thereto) will be final and binding. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been cured or waived. None of the Purchaser, any of its affiliates or assigns, the Dealer Managers, the Information Agent, the Depositary or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. THE PURCHASER'S ACCEPTANCE FOR PAYMENT OF SHARES TENDERED PURSUANT TO THE OFFER WILL CONSTITUTE A BINDING AGREEMENT BETWEEN THE TENDERING STOCKHOLDER AND THE PURCHASER UPON THE TERMS AND SUBJECT TO THE CONDITIONS OF THE OFFER. 36 37 WITHDRAWAL RIGHTS Except as otherwise provided in this Section, tenders of Shares made pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Date and, unless previously accepted for payment as provided herein, may also be withdrawn at any time after May 8, 2000. If the Purchaser extends the Offer, is delayed in, or delays, its acceptance for payment or payment for Shares or is unable to accept for payment or pay for Shares for any reason, then, without prejudice to the Purchaser's other rights under the Offer, tendered Shares may nevertheless be retained by the Depositary, on behalf of the Purchaser, and may not be withdrawn except to the extent tendering stockholders are entitled to and duly exercise withdrawal rights as described in this Section. Any such extension or delay will be accompanied by an extension of the Offer to the extent required by law. In order for a withdrawal to be effective, a written, telegraphic or facsimile transmission notice of withdrawal must be timely received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase. Any such notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder of the Shares to be withdrawn, if different from that of the person who tendered such Shares. If Share Certificates to be withdrawn have been delivered or otherwise identified to the Depositary, then, prior to the physical release of such Share Certificates, the tendering stockholder must also submit the serial numbers shown on such Share Certificates to the Depositary, and the signatures on the notice of withdrawal must be guaranteed by an Eligible Institution, unless such Shares have been tendered for the account of an Eligible Institution. If Shares have been tendered pursuant to the procedures for book-entry transfer, as set forth in "--Procedures For Accepting The Offer And Tendering Shares," any notice of withdrawal must specify the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares and must otherwise comply with the procedures of the Book-Entry Transfer Facility. Withdrawals may not be revoked and any Shares properly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered at any time prior to the Expiration Date by following the procedures described in "--Procedures For Accepting The Offer And Tendering Shares." All questions as to the form and validity (including the time of receipt) of any notice of withdrawal will be determined by the Purchaser, in its sole discretion, which determination will be final and binding on all parties.

which in the reasonable judgment of the Purchaser, in any such case, and regardless of the circumstances giving rise to such condition, makes it inadvisable to proceed with the Offer, the Merger and/or with such acceptance for payment or payments. The foregoing conditions are for the sole benefit of the Purchaser and its affiliates and may be asserted by the Purchaser regardless of any circumstances giving rise to any condition and may be waived by the Purchaser, in whole or in part, at any time and from time to time in the reasonable discretion of the Purchaser. The failure by the Purchaser (or any affiliate of the Purchaser) at any time to exercise any of the foregoing rights will not be deemed a waiver of any right, and each right will be deemed an ongoing right which may be asserted at any time and from time to time. 39 40 CERTAIN LEGAL MATTERS; REGULATORY APPROVALS GENERAL. Except as described below, none of Thermo Electron, Thermedics, Corpak or the Purchaser is aware of any license or regulatory permit that appears to be material to the business of the Company and its subsidiaries that might be adversely affected by the Purchaser's acquisition of Shares as contemplated herein. Except as described in this section, none of Thermo Electron, Thermedics, Corpak or the Purchaser is aware of any other material filing, approval or other action by any federal or state governmental or administrative authority that would be required for the acquisition of Shares by the Purchaser as contemplated herein. Should any such other approval or action be required, it is currently contemplated that such approval or other action would be sought. There is, however, no present intention to delay the purchase of Shares tendered pursuant to the Offer or the Merger pending the outcome of any such other approval or action. There can be no assurance that any such other approval or action, if needed, would be obtained without substantial conditions or that adverse consequences might not result to the Purchaser's, Corpak's, Thermedics', Thermo Electron's or the Company's business in the event that such other approvals were not obtained or such other actions were not taken. The Purchaser's obligation under the Offer to accept for payment and pay for Shares is subject to certain conditions, including conditions relating to the legal matters discussed in this section. See "--Certain Conditions Of The Offer." ANTITRUST. The Purchaser believes that the Offer and the Merger are exempt from the reporting requirements contained in the Hart-Scott-Rodino Antitrust Improvements Act of 1976. Nevertheless, there can be no assurance that a challenge to the Offer and the Merger on antitrust grounds will not be made, or, if such challenge is made, what the result will be. FOREIGN APPROVALS. The Company conducts business in a number of foreign countries and jurisdictions. In connection with the acquisition of the Shares pursuant to the Offer or the Merger, the laws of certain of those foreign countries and jurisdictions may require the filing of information with, or the obtaining of the approval or consent of, governmental authorities in such countries and jurisdictions. The governments in such countries and jurisdictions might attempt to impose additional conditions on the Company's operations conducted in such countries and jurisdictions as a result of the acquisition of the Shares pursuant to the Offer or the Merger. If such approvals or consents are found to be required, the Purchaser intends to make the appropriate filings and applications. In the event such a filing or application is made for the requisite foreign approvals or consents, there can be no assurance that such approvals or consents will be granted and, if such approvals or consents are received, there can be no assurance as to the date of such approvals or consents. In addition, there can be no assurance that the Purchaser will be able to cause the Company or its subsidiaries to satisfy or comply with such laws or that compliance or noncompliance will not have adverse consequences for the Company or any subsidiary after purchase of the Shares pursuant to the Offer or the Merger. STATE ANTI-TAKEOVER STATUTES. Several Massachusetts statutes prohibit, restrict or impose certain procedural and disclosure requirements with respect to the acquisition of more than 10% of the outstanding shares of a Massachusetts corporation and with respect to take-over bids and business combinations involving a Massachusetts corporation. These are Chapters 110C, 110D and 110F of the General Laws of the Commonwealth of Massachusetts. Based on Thermo Electron's and its subsidiaries' equity holdings in the Company, the Purchaser believes that neither the Offer nor the Merger is prohibited by these statutes. A number of other states have adopted laws and regulations applicable to attempts to acquire securities of corporations which are incorporated, or have substantial assets, stockholders, principal executive offices or principal places of business, or whose business operations otherwise have substantial economic effects, in such states. In 1982, in Edgar v. MITE Corp., the Supreme Court of the United States invalidated on constitutional grounds the Illinois Business Takeover Statute, which, as a matter of state securities law, made takeovers of corporations meeting certain requirements more difficult. However, in 1987 in CTS Corp. v. Dynamics Corp. of America, the Supreme Court held that the State of Indiana may, as a matter of corporate law, and, in particular, with respect to those aspects of corporate law concerning corporate governance, constitutionally disqualify a potential acquiror from voting on the affairs of a target corporation without the prior approval of the remaining stockholders. The state law before the Supreme Court was by its terms applicable only to corporations that had a substantial number of stockholders in that state and were incorporated there. 40 41 The Company, directly or through subsidiaries, conducts business in a number of states throughout the United States, some of which have enacted takeover laws. None of Thermo Electron, Thermedics, Corpak or the Purchaser knows whether any of these laws will, by their terms, apply to the Offer or the Merger, and the Purchaser has not necessarily complied with any such laws. Should any person seek to apply any state takeover law, the Purchaser will take such action as then appears desirable, which may include challenging the validity or applicability of any such statute in appropriate court proceedings. In the event it is asserted that one or more state takeover laws is applicable to the Offer or the Merger, and an appropriate court does not determine that it is inapplicable or invalid as applied to the Offer or the Merger, the Purchaser might be required to file certain information with, or receive approvals from, the relevant state authorities. In addition, if enjoined, the Purchaser might be unable to accept for payment any Shares tendered pursuant to the Offer or be delayed in continuing or consummating the Offer. In such case, the Purchaser may not be obligated to accept for payment any Shares tendered. See "--Certain Conditions Of The Offer." DIVIDENDS AND DISTRIBUTIONS If, on or after January 31, 2000, the Company should declare or pay any dividend or other distribution (including, without limitation, the issuance of additional Shares pursuant to a stock dividend or stock split or the issuance of rights for the purchase of any securities) with respect to the Shares that is payable or distributable to stockholders of record on a date occurring prior to the transfer to the name of the Purchaser or its nominees or transferees on the Company's stock transfer records of the Shares purchased pursuant to the Offer, then, without prejudice to the Purchaser's rights described in "--Certain Conditions Of The Offer," (1) the purchase price per Share payable by the Purchaser pursuant to the Offer will be reduced in the amount of any such cash dividend or distribution, and (2) the whole of any non-cash dividend or distribution (including, without limitation, additional Shares or rights as aforesaid) will be required to be remitted promptly and transferred by each tendering stockholder to the Depositary for the account of the Purchaser accompanied by appropriate documentation of transfer. Pending such remittance or appropriate assurance thereof, the Purchaser will be entitled to all rights and privileges as owner of any such non-cash dividend, distribution or right, and may withhold the entire purchase price or deduct from the purchase price the amount of value of such non-cash dividend, distribution or right, as determined by the Purchaser in its sole discretion. If, on or after January 31, 2000, the Company should split the Shares or combine or otherwise change the Shares or its capitalization, then, without prejudice to the Purchaser's rights described under the heading "--Certain Conditions Of The Offer," appropriate adjustments to reflect such split, combination or change may be made by the Purchaser in the purchase price and other terms of the Offer, including, without limitation, the number or type of securities offered to be purchased. 41 42 CERTAIN FEDERAL INCOME TAX CONSEQUENCES The following is a general summary of the material U.S. federal income tax consequences of the Offer and the Merger to the beneficial owners of Shares. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the "Code"), applicable treasury regulations thereunder, judicial decisions and current administrative rulings as in effect on the date of this Offer to Purchase. The discussion does not address all aspects of U.S. federal income taxation that may be relevant to particular taxpayers in light of their personal circumstances or to taxpayers subject to special treatment under the Code (for example, life insurance companies, foreign corporations, foreign partnerships, foreign estates or trusts, or individuals who are not citizens or residents of the United States and beneficial owners whose Shares were acquired pursuant to the exercise of warrants, employee stock options or otherwise as compensation) and does not address any aspect of state, local, foreign or other taxation. The receipt of cash for Shares pursuant to the Offer or the Merger will be a taxable transaction for federal income tax purposes under the Code, and may also be a taxable transaction under applicable state, local or foreign income or other tax laws. Generally, for federal income tax purposes, a beneficial owner of Shares that tenders Shares pursuant to the Offer or surrenders Shares pursuant to the Merger will recognize gain or loss equal to the difference between the amount of cash received by the beneficial owner and the aggregate tax basis in the Shares sold pursuant to the Offer or canceled and converted to cash pursuant to the Merger. Gain or loss will be calculated separately for each block of Shares purchased pursuant to the Offer or canceled and converted to cash pursuant to the Merger. Gain or loss on the disposition of Shares generally will be capital gain or loss, assuming that the Shares are held as capital assets, and that a beneficial owner of Shares does not, directly or under the attribution rules of Sections 304 and 318 of the Code, own Shares or stock of the Surviving Corporation following the Offer and the Merger. Capital gains of individuals, estates and trusts generally are subject to a maximum federal income tax rate of (i) 20% if, at the time the tendered Shares are accepted for payment (in the case of the Offer) or the Effective Time of the Merger (in the case of the Merger), the beneficial owner held the Shares for more than one year or (ii) 39.6% if, at the time the tendered Shares are accepted for payment (in the case of the Offer) or the Effective Time of the Merger (in the case of the Merger), the beneficial owner held the Shares for not more than one year. Capital gains of corporations generally are taxed at the federal income tax rates applicable to corporate ordinary income. In addition, the ability of both corporate and non-corporate beneficial owners to use capital losses to offset ordinary income is limited. In general, cash received by Public Stockholders who exercise statutory appraisal rights ("Dissenting Stockholders") in respect of such appraisal rights will result in the recognition of gain or loss to the Dissenting Stockholders. Any such Dissenting Stockholder should consult with its tax advisor for a full understanding of the tax consequences of the receipt of cash in respect of appraisal rights pursuant to the Merger. A beneficial owner may be subject to backup federal income tax withholding at a rate of 31% with respect to the amount of cash received pursuant to the Offer or the Merger unless the owner provides its tax identification number ("TIN") and certifies that such number is correct or properly certifies that it is awaiting a TIN, or unless an exemption applies. A beneficial owner that does not furnish its TIN may be subject to a penalty imposed by the Internal Revenue Service. See "The Tender Offer--Procedures For Accepting The Offer And Tendering Shares--Backup Federal Income Tax Withholding." If backup withholding applies to a beneficial owner, the Depositary is required to withhold 31% from payments to such owner. Backup withholding is not an additional tax. Rather, the amount of the backup withholding can be credited against the federal income tax liability of the person subject to the backup withholding, provided that the required information is given to the Internal Revenue Service. If backup withholding results in an overpayment of tax, a refund can be obtained by the beneficial owner upon filing an income tax return. EACH BENEFICIAL OWNER OF SHARES IS URGED TO CONSULT SUCH BENEFICIAL OWNER'S TAX ADVISOR AS TO THE SPECIFIC TAX CONSEQUENCES TO SUCH BENEFICIAL OWNER OF THE OFFER AND THE MERGER, INCLUDING THE APPLICATION OF STATE, LOCAL, FOREIGN AND OTHER TAX LAWS. 42 43 PRICE RANGE OF THE SHARES; DIVIDENDS PRICE RANGE OF SHARES.

CERTAIN TRANSACTIONS Except as otherwise set forth in this Offer to Purchase, none of the Purchaser, Corpak, Thermedics or Thermo Electron or, to the best knowledge of the Purchaser, Corpak, Thermedics and Thermo Electron, any of the persons listed on Schedule I hereto, has any contract, arrangement, understanding or relationship with any other person with respect to any Shares or other securities of the Company, including, but not limited to, any contract, arrangement, understanding or relationship concerning the transfer or voting of any such Shares or other securities, joint ventures, loan or option arrangements, puts or calls, guaranties of loans, guaranties against loss or the giving or withholding of proxies. PRIOR CONTACTS. Except as set forth in this Offer to Purchase (particularly the section entitled "Special Factors--Background To The Offer And The Merger"), since January 1, 1998, there have been no contacts, negotiations or transactions between the Purchaser, Corpak, Thermedics, Thermo Electron, any subsidiary of the Purchaser, Corpak, Thermedics or Thermo Electron or, to the best knowledge of the Purchaser, Corpak, Thermedics and Thermo Electron, any of the persons listed on Schedule I hereto, on the one hand, and the Company or any of its officers, directors or affiliates, on the other hand, concerning a merger, consolidation or acquisition, a tender offer or other acquisition of securities, an election of directors, or a sale or other transfer of a material amount of assets, other than votes cast by Thermo Electron or Thermedics for the election of directors of the Company in the normal course. PRIOR BUSINESS RELATIONSHIPS. Except as set forth in this Offer to Purchase, none of the Purchaser, Corpak, Thermedics or Thermo Electron or, to the best knowledge of the Purchaser, Corpak, Thermedics or Thermo Electron, any of the persons listed on Schedule I hereto has, since January 1, 1998, had any business relationships or transactions with the Company or any of its executive officers, directors or affiliates that would require disclosure herein under the rules and regulations of the Commission applicable to the Offer or the Merger. TRANSACTIONS BETWEEN THE COMPANY AND THERMEDICS OR THERMO ELECTRON. On May 6, 1998, the Company entered into an Agreement and Plan of Reorganization with Thermedics, Orion Research Inc. ("Orion Research"), a wholly-owned subsidiary of Thermedics, and Orion Acquisition Inc., a wholly-owned subsidiary of the Company. The agreement provided for the acquisition by the Company of Orion Research in exchange for the issuance of 5,961,225 shares of the Company's common stock to Thermedics. Based on the average of the closing prices of the Company's common stock as reported on the American Stock Exchange for the five trading days ending on April 13, 1998 (the date preceding the Company's announcement of its 49 50 intention to acquire Orion Research), the shares to be issued to Thermedics had a value of $65,800,000 prior to such announcement. FINANCIAL INFORMATION. Because the Offer Price will be paid in cash, the Purchaser, Corpak, Thermedics and Thermo Electron do not believe that financial information with respect to the Purchaser, Corpak, Thermedics, Thermo Electron and their subsidiaries would be material to a stockholder's evaluation of the Offer and the Merger. Financial information concerning Thermedics, Thermo Electron and their subsidiaries is filed by Thermedics and Thermo Electron with the Commission (which may be inspected and copies thereof obtained at the offices of the Commission as set forth in "Certain Information Concerning The Company"). 50 51 SOURCE AND AMOUNT OF FUNDS The total amount of funds required by the Purchaser to purchase all of the outstanding Shares pursuant to the Offer and the Merger, and to pay related fees and expenses, is estimated to be approximately $18.5 million. The Purchaser will obtain the funds to purchase the Shares in the Offer and the Merger from Thermedics as a loan or capital contribution. Thermedics will use a combination of its own working capital and borrowings from Thermo Electron to fund this loan or capital contribution. Thermo Electron has committed to provide any required financing to Thermedics. Any loan by Thermo Electron to Thermedics will be evidenced by an unsecured note due September 1, 2000 that will bear interest at a floating rate equal to the 30-day Dealer Commercial Paper Rate (the "DCP Rate") plus 150 basis points, adjusted at the beginning of each fiscal month of Thermedics. The interest rate of the note will be reduced to the DCP Rate plus 50 basis points to the extent of any funds invested by Thermedics' majority-owned subsidiaries in Thermo Electron's cash management arrangement. Thermedics does not have any arrangement with respect to the repayment of any such loan. 51 52 THE MERGER; APPRAISAL RIGHTS THE MERGER Following the consummation of the Offer, subject to the terms and conditions and in accordance with the Chapter 156B of the Massachusetts General Laws (the "Massachusetts Business Corporation Law"), Thermedics plans to cause the Company to merge with and into the Purchaser. Upon the Effective Date of the Merger: - each Share issued and outstanding immediately prior to the Effective Date of the Merger (other than Shares held by Public Stockholders, if any, who are entitled to and who properly exercise their dissenters' rights (See "--Appraisal Rights" below) under the Massachusetts Business Corporation Law) will be cancelled and extinguished and be converted into and become a right to receive the Offer Price per Share; and - each outstanding share of the Purchaser's capital stock issued and outstanding immediately prior to the Effective Date of the Merger will be converted into one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. In the Merger, the Purchaser would be the Surviving Corporation and would change its name to "Thermedics Detection Inc." As a result of the Merger, Corpak and Thermo Electron will own all of the outstanding equity interests in the Surviving Corporation. Under the Massachusetts Business Corporation Law, if the Purchaser holds at least 90% of the outstanding Shares, the Purchaser would have the power to effect the Merger without a vote of the Company's Board of Directors or other stockholders. The Purchaser intends to take all necessary and appropriate action to cause the Merger to become effective as soon as reasonably practicable after the consummation of the Offer and without a meeting of the Company's stockholders. APPRAISAL RIGHTS Stockholders who tender their Shares in the Offer are not entitled to appraisal rights under the Massachusetts Business Corporation Law. If the Purchaser effects the Merger, then Company stockholders who do not tender their Shares to the Purchaser pursuant to the Offer would have the right to demand an appraisal of the fair value of their Shares in accordance with the provisions of Sections 89 through 98 of the Massachusetts Business Corporation Law (the "Massachusetts Appraisal Statute"), which sets forth the rights and obligations of Company stockholders demanding an appraisal and the procedures to be followed. The following is a summary of the procedures to be followed under the Massachusetts Appraisal Statute, the full text of which is attached to this Offer to Purchase as Schedule III. The summary does not purport to be a complete statement of, and is qualified in its entirety by reference to, the Massachusetts Appraisal Statute and to any amendments to such statute after the date of this Offer to Purchase. Failure to follow the Massachusetts Appraisal Statute procedures may result in termination or waiver of appraisal rights under the Massachusetts Appraisal Statute. If the Merger is consummated, any Company stockholder who desires to exercise his appraisal rights should review carefully the Massachusetts Appraisal Statute and is urged to consult his legal advisor before electing or attempting to exercise such rights. Only a holder of record of Shares on the Effective Date of the Merger would be entitled to seek appraisal. The demand for appraisal must be executed by or for the holder of record, fully and correctly, as such holder's name appears on the holder's Share Certificates. If the Shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, the demand should be made in that capacity, and if the Shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand must be made by or for all owners of record. An authorized agent, including one or more joint owners, could execute the demand for appraisal for a holder of record; however, such agent must identify the record owner or owners and expressly disclose in such demand that the agent is acting as agent for the record owner or owners of such Shares. 52 53 A record holder such as a broker who holds Shares as a nominee for beneficial owners, some of whom desire to demand appraisal, would be required to exercise appraisal rights on behalf of such beneficial owners with respect to the Shares held for such beneficial owners. In such case, the written demand for appraisal should set forth the number of Shares covered by it. Unless a demand for appraisal specifies a number of Shares, such demand will be presumed to cover all Shares held in the name of such record owner. The Surviving Corporation would mail written notice to the stockholders of record of the Company on the Effective Date of the Merger of the approval and consummation of the Merger and the availability of appraisal rights under the Massachusetts Appraisal Statute within ten days after the Effective Date of the Merger (the "Merger Notice"). Any stockholder entitled to appraisal rights would have the right, on or before the date that is 20 days after the date of mailing of the Merger Notice, to demand in writing from the Surviving Corporation an appraisal of his Shares. Such demand will be sufficient if it reasonably informs the Surviving Corporation of the identity of the stockholder and that the stockholder intends to demand an appraisal of the fair value of his or her Shares. Failure to make such a demand on or before the date that is 20 days after the date of mailing of the Merger Notice would foreclose a stockholders' rights to appraisal. A stockholder could withdraw his demand for appraisal only with the approval of the Surviving Corporation. Upon withdrawal of a demand for appraisal, a stockholder would be entitled to receive the Offer Price. If, following the Merger, a stockholder perfects a demand for payment of his or her Shares as provided above (each, a "Dissenting Stockholder"), and if the Surviving Corporation and such Dissenting Stockholder are able to reach agreement on the fair value of the Shares, the Surviving Corporation will pay to the Dissenting Stockholder the fair value of such Shares, as the case may be, within 30 days after the expiration of the 20-day period during which the demand for appraisal may be made (the "30-Day Period"). If within the 30-Day Period the parties fail to agree as to the fair value of such Shares, either the Surviving Corporation or the Dissenting Stockholder may have the fair value of the Shares of all Dissenting Stockholders determined by judicial proceedings by filing a bill in equity in the Massachusetts Superior Court for Middlesex County within four months after the expiration of the 30-Day Period. While Massachusetts courts have broad discretion in determining fair value of stock of dissenting stockholders, Massachusetts courts have generally used a weighted average of the market, earnings and asset values for the stock. The Massachusetts Supreme Judicial Court has recently held that such method is an appropriate, but not mandated, approach to determining the fair value of stock of dissenting stockholders, and that such valuation is within the discretion of the trial judge. A fair rate of interest, if any, shall be paid by the Surviving Corporation on any award determined by the Court from the date of the vote of the Board of Directors of the Purchaser approving the Merger. If (i) no suit is filed to determine the value of the Shares within four months of the expiration of the 30-Day Period, (ii) any such suit is dismissed as to that Dissenting Stockholder or (iii) the Dissenting Stockholder withdraws his, her or its objection in writing with the written approval of the Surviving Corporation, the Dissenting Stockholder will have only the rights of a nondissenting stockholder to receive the Offer Price. Under Massachusetts statutory law, the enforcement by a Dissenting Stockholder of such Dissenting Stockholder's right to receive payment for his or her shares in the manner provided by the Massachusetts Appraisal Statute is stated to be the exclusive remedy of a stockholder objecting to the Merger, except upon the grounds that consummation of the Merger will be or is illegal or fraudulent as to such stockholder. The Massachusetts Supreme Judicial Court, however, has held that Dissenting Stockholders are not limited to the statutory remedy of judicial appraisal in cases where violations of fiduciary duty are found. Stockholders considering seeking appraisal should have in mind that the fair value of their Shares determined under the Massachusetts Appraisal Statute could be more, the same or less than the Offer Price and that investment banking opinions as to fairness from a financial point of view are not necessarily opinions as to fair value under the Massachusetts Appraisal Statute. From and after the Effective Date of the Merger, Dissenting Stockholders would not be entitled to vote their Shares for any purpose and would not be entitled to receive payment of dividends or other distributions in respect of such Shares payable to stockholders of record thereafter. 53 54 THE FOREGOING SUMMARY DOES NOT PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE FOLLOWED BY STOCKHOLDERS DESIRING TO EXERCISE THEIR DISSENTING APPRAISAL RIGHTS AND IS QUALIFIED IN ITS ENTIRETY BY EXPRESS REFERENCE TO THE MASSACHUSETTS APPRAISAL STATUTE, THE FULL TEXT OF WHICH IS ATTACHED HERETO AS SCHEDULE III. STOCKHOLDERS ARE URGED TO READ SCHEDULE III IN ITS ENTIRETY SINCE FAILURE TO COMPLY WITH THE PROCEDURES SET FORTH THEREIN MAY RESULT IN THE LOSS OF APPRAISAL RIGHTS. 54 55 FEES AND EXPENSES The Advisors are acting as financial advisors to Thermedics and Thermo Electron in connection with the Offer and the Merger.

The notice may be in such form as the directors or officers calling the meeting deem advisable, but the following form of notice shall be sufficient to comply with this section: "If the action proposed is approved by the stockholders at the meeting and effected by the corporation, any stockholder (1) who files with the corporation before the taking of the vote on the approval of such action, written objection to the proposed action stating that he intends to demand payment for his shares if the action is taken and (2) whose shares are not voted in favor of such action has or may have the right to demand in writing from the corporation (or, in the case of a consolidation or merger, the name of the resulting or surviving corporation shall be inserted), within twenty days after the date of mailing to him of notice in writing that the corporate action has become effective, payment for his shares and an appraisal of the value thereof.
