THE COMPANY The Company is a provider of environmental services and infrastructure planning and design, encompassing a range of specializations within the consulting and design, remediation and recycling, laboratory testing, and metal-treating industries. Consulting and Design - The Company's Bettigole Andrews & Clark Inc. and Normandeau Associates Inc. subsidiaries provide both private and public sector clients with a range of consulting services that address transportation planning and design, and natural resource management issues, respectively. In February 1995, the Company acquired Elson T. Killam Associates Inc., which provides environmental consulting and engineering services and specializes in wastewater treatment and water resources management. Remediation and Recycling - The Company's majority-owned Thermo Remediation Inc. ("Thermo Remediation") subsidiary operates a network of soil-remediation centers, serving customers in more than a dozen states by providing thermal treatment of soil to remove and destroy petroleum contamination caused by leaking underground and aboveground storage tanks, spills, and other sources. Thermo Remediation's Thermo Fluids Inc. subsidiary, located in Arizona, offers fluids-recycling services including waste motor oil and wastewater treatment throughout Arizona and in neighboring states. In addition, Thermo Remediation's Remediation Technologies, Inc. subsidiary, acquired in December 1995, is an integrated environmental services firm, with 15 offices nationwide, that focuses primarily on the remediation of former and active industrial sites contaminated with organic wastes and residues. Through its Thermo Nutech division ("Thermo Nutech"), Thermo Remediation provides services to remove radioactive contaminants from sand, gravel, and soil, as well as health physics, radiochemistry laboratory, and radiation dosimetry services. Thermo Nutech was formerly part of a joint venture between the Company and Thermo Instrument Systems Inc. 9 PAGE The Company's majority-owned Thermo EuroTech N.V. subsidiary, formerly known as J. Amerika N.V. ("Thermo EuroTech"), located in the Netherlands, provides wastewater treatment services as well as services to test, remove and install underground storage tanks. In March 1995, Thermo EuroTech acquired Refining and Trading Holland B.V., which specializes in converting "off-spec" and contaminated petroleum fluids into usable oil products. Laboratory Testing - The Company's Thermo Analytical Inc. subsidiary operates a network of analytical laboratories that provide environmental testing services to commercial and government clients throughout the U.S. The May 1995 acquisition of Lancaster Laboratories expands the Company's range of contract services beyond environmental testing to the pharmaceutical- and food-testing industries. Metal Treating - The Company performs metallurgical processing services, using thermal-treatment equipment at locations in California and Minnesota. The Company also designs, manufactures, and installs advanced custom-engineered, thermal-processing systems through its equipment division located in MichigaN. The Company is a majority-owned, publicly traded subsidiary of Thermo Electron. As of December 30, 1995, Thermo Electron owned 14,119,858 shares of the Common Stock of the Company, representing approximately 81% of such Common Stock outstanding. The Company's principal executive offices are located at 81 Wyman Street, Waltham, Massachusetts 02254, and its telephone number is (617) 622-1000. This Prospectus is accompanied by (i) a copy of the Company's Annual Report on Form 10-K, as amended on Form 10-K/A, for the fiscal year ended April 1, 1995 and (ii) a copy of the Company's Quarterly Report on Form 10-Q for the most recent quarter ended after April 1, 1995. RECENT DEVELOPMENTS On May 4, 1995, the Company's Thermo Remediation subsidiary issued $37,950,000 aggregate principal amount of its 4 7/8% Convertible Subordinated Debentures due 2000. The debentures are convertible at the option of the holders thereof into shares of Thermo Remediation's common stock at an initial conversion price (subject to future adjustments) of $17.92 per share. On December 8, 1995, Thermo Remediation acquired all of the issued and outstanding capital stock of Remediation Technologies, Inc. ("RETEC") for a combination of cash and securities having an aggregate value of approximately $29.7 million. The purchase price consisted of approximately $18.5 million in cash and units consisting of (i) 227,250 shares of Thermo Remediation's common 10 PAGE stock and (ii) warrants to purchase 75,750 additional shares of Thermo Remediation's common stock at an exercise price of $14.85 per share, such units having an aggregate value of approximately $3.7 million. In addition, Thermo Remediation assumed outstanding RETEC stock options and converted such options into options to purchase up to 897,000 shares of Thermo Remediation common stock. The shares of such common stock issuable upon exercise of such options are subject to certain restrictions on resale, which restrictions lapse ratably over a period of five years. As converted, such options have a weighted average exercise price of $4.24 per share and were valued in the aggregate at approximately $7.5 million. RETEC recorded revenues of approximately $39 million in the fiscal year ended December 31, 1994. USE OF PROCEEDS None of the proceeds from the sale of the Warrants by the Selling Securityholders will be received by the Company. The proceeds from the exercise of the Warrants, if any, will be used by the Company for general corporate purposes.

The Warrants are being registered to permit public secondary trading of the Warrants from time to time by the Selling Securityholders. All of the Warrants were acquired by the Selling Securityholders or their affiliates from the Company in private placement transactions pursuant to Securities Purchase Agreements with the Company dated as of December 20, 1991, March 20, 1992, June 15, 1992, September 1, 1992, December 16, 1992, and March 18, 1993 (the "Purchase Agreements"). The Shares are issuable upon exercise of certain of the Warrants at an exercise price of $10.00 per Share and upon the exercise of certain other Warrants at an exercise price of $11.34 per Share. In the Purchase Agreements, the Company agreed, among other things, to bear all expenses (other than underwriting discounts, selling commissions, and fees and expenses of counsel and other advisors to the Selling Securityholders) in connection with the registration and sale of the Warrants being offered by the Selling Securityholders. See "Sale of Securities." The Company has agreed to prepare and file such amendments and supplements to the Registration Statement of which this Prospectus forms a part as may be necessary to keep the Registration Statement effective until all the Warrants offered hereby have been sold pursuant thereto or until such Warrants are no longer, by reason of Rule 144(k) under the Securities Act or any other rule of similar effect, required to be registered for the public sale thereof by the Selling Securityholders. 13 PAGE SALE OF SECURITIES The Company has been advised that the Selling Securityholders may sell Warrants from time to time in negotiated transactions, at fixed prices which may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market price or at negotiated prices. The Selling Securityholders may effect such transactions by selling the Warrants to or through broker-dealers, and such broker-dealers may receive compensation in the form of discounts, concessions or commissions from the Selling Securityholders and/or the purchasers of the Warrants for whom such broker-dealers may act as agent or to whom they sell as principal, or both (which compensation to a particular broker-dealer might be in excess of customary commissions). The Selling Securityholders and any broker-dealers who act in connection with the sale of Securities hereunder may be deemed to be "underwriters" as that term is defined in the Securities Act, and any commissions received by them and profit on any resale of the Securities as principal might be deemed to be underwriting discounts and commissions under the Securities Act. The Company has agreed to indemnify the Selling Securityholders against certain liabilities, including liabilities under the Securities Act as underwriter or otherwise. DESCRIPTION OF WARRANTS The following is a brief description of the principal terms applicable to the Warrants. The Warrants represent the right, exercisable during a prescribed period of time, to purchase shares of the Common Stock of the Company at prescribed prices. The Warrants were acquired by the Selling Securityholders or their affiliates from the Company in private placement transactions pursuant to Purchase Agreements dated as of December 20, 1991, March 20, 1992, June 15, 1992, September 1, 1992, December 16, 1992, and March 18, 1993. Exercise Period and Procedure. The registered holder of a Warrant may exercise the Warrant, in whole or in part (but not as to fractional Shares) at any time and from time to time after the date of this Prospectus and prior to the fifth anniversary of such date (the "Exercise Period"). Certificates for Shares purchased upon exercise of a Warrant will be delivered by the Company to the purchaser within ten days after the Company has received a completed and executed exercise agreement, in the form attached to the Warrant, and a check representing the exercise price of the Shares for which the Warrant is exercised (the "Exercise Date"). Shares issuable upon the exercise of a Warrant will be deemed to have been issued to the purchaser on the Exercise Date, and the purchaser will be deemed for all purposes 14 PAGE to have been the record holder of such Shares on the Exercise Date. Unless an exercised Warrant has expired or all of the purchase rights represented thereby have been exercised, the Company will prepare a new Warrant, substantially identical thereto, representing the rights formerly represented by such Warrant which have not expired or been exercised. The Warrants may not be exercised as to fractional Shares. If a fractional Share would otherwise be issuable upon exercise of a Warrant, the Company will, within ten days after the Exercise Date, deliver to the purchaser a check payable to the purchaser in lieu of such fractional share, in an amount equal to the market price of such fractional Share as of the close of business on the Exercise Date. The issuance of certificates for Shares upon exercise of a Warrant will be made without charge to the registered holder for any issuance tax in respect thereof or any other cost incurred by the Company in connection with such exercise and the related issuance of such Shares. The Company will not, however, be required to pay any tax which may be payable in respect of any transfer, in whole or in part, of any Warrant (including the issuance of new Warrants in connection therewith) or the delivery of stock certificates in a name other than that of the registered holder of a Warrant presented for exercise, and any such tax must be paid by such registered holder at the time of presentation. The Company will not close its books for the transfer of the Warrants or of any Shares issued or issuable upon the exercise on the Warrants in any manner which interferes with the timely exercise of the Warrants. Exercise Price. The Warrants issued pursuant to the Purchase Agreements dated as of December 20, 1991, March 20, 1992, June 15, 1992 and September 1, 1992 may be exercised at an exercise price of $10.00 per Share, and the Warrants issued pursuant to the Purchase Agreements dated as of December 16, 1992 and March 18, 1993 may be exercised at an exercise price of $11.34 per Share (as the case may be, the "Exercise Price"). The Exercise Price of each Warrant was determined after taking into account several factors, including (a) the fair market values of the Common Stock underlying the Warrants on their respective dates of issuance, (b) the appropriate premiums over such fair market values compared to premiums applicable to listed or quoted options on similar securities, (c) the degree of volatility in such fair market values prior to such issuance and (d) the length of the Exercise Period. Adjustments. In order to prevent dilution of the rights granted under the Warrants, both the Exercise Price and the number of Shares that may be issued upon exercise of the Warrants will be subject to adjustment from time to time if, during the Exercise Period, the Company (a) issues any shares of Common Stock as a dividend upon Common Stock, or (b) issues any shares of Common Stock by reclassification or otherwise, (c) combines 15 PAGE outstanding shares of Common Stock, by reclassification or otherwise or (d) declares a dividend upon the Common Stock payable otherwise than out of earnings or retained earnings and otherwise than in Common Stock. No adjustment of the Exercise Price will be made if the amount of such adjustment would be less than one cent per Share, but in such case any adjustment that would otherwise be required then to be made will be carried forward and will be made at the time and together with the next subsequent adjustment which, together with any adjustment or adjustments so carried forward, would amount to not less than one cent per share. Upon any reorganization or reclassification of the capital stock of the Company, or any consolidation or merger of the Company with another corporation (other than a consolidation or merger in which the Company is the surviving entity and which does not result in any change in the Common Stock), or any sale or other disposition by the Company of all or substantially all of its assets to any other corporation, the Warrants will thereafter be exercisable for the number of shares of stock or other securities or property of the Company, or of the successor corporation resulting from such consolidation or merger, as the case may be, to which the Shares (and any other securities and property) of the Company, deliverable upon the exercise of the Warrants, would have been entitled upon such reorganization, reclassification of capital stock, consolidation, merger, sale or other disposition if the Warrants had been exercised immediately prior to such reorganization, reclassification of capital stock, consolidation, merger, sale or other disposition. No Voting Rights. The Warrants will not entitle the holders thereof to any voting rights or other rights as stockholders of the Company. Miscellaneous. The Warrants and all rights thereunder are transferable, in whole or in part, without charge to the registered holder, upon surrender of the Warrants with properly executed assignment (in the form attached to the Warrants) at the principal office of the Company. Similarly, the Warrants are exchangeable, upon the surrender thereof by the registered holder at the principal office of the Company, for new Warrants of like tenor representing in the aggregate the purchase rights thereunder, and each of such new Warrants will represent such portion of such rights as is designated by the registered holder at the time of such surrender. The provisions of the Warrants may be amended and the Company may take any action therein prohibited, or omit to perform any act therein required to be performed by it, only if the Company has obtained the written consent of the registered holders of Warrants representing at least 50% of the shares obtainable upon the exercise of the Warrants outstanding at the time of such consent. 16 PAGE DESCRIPTION OF COMMON STOCK The following is a brief description of the principal terms applicable to the authorized shares of the Company's Common Stock. Each share of Common Stock is entitled to pro rata participation in distributions upon liquidation and to one vote on all matters submitted to a vote of stockholders. Dividends may be paid to the holders of Common Stock when and if declared by the Board of Directors out of funds legally available therefor. Holders of Common Stock have no preemptive or similar rights. The outstanding shares of Common Stock are, and the Shares offered hereby will be, legally issued, fully paid and nonassessable. The shares of Common Stock have noncumulative voting rights, which means that the holders of a majority of the shares voting can elect all the Directors if they so choose, and in such event, the holders of the remaining shares cannot elect any Directors. As of December 30, 1995, Thermo Electron beneficially owned 14,119,858 shares of Common Stock, which represented approximately 81% of the then outstanding Common Stock. It is anticipated that Thermo Electron will continue to beneficially own at least a majority of the outstanding Common Stock, and will have the power to elect all of the members of the Company's Board of Directors. The Company's Certificate of Incorporation contains certain provisions permitted under the General Corporation Law of the State of Delaware relating to the liability of Directors. The provisions eliminate a Director's liability for monetary damages for a breach of fiduciary duty, except in certain circumstances involving wrongful acts or omissions, which involve intentional misconduct or a knowing violation of law. The Company believes that these provisions will assist the Company in attracting and retaining qualified individuals to serve as Directors and officers.

Indemnification of Directors and Officers. The Delaware General Corporation Law and the Company's Restated Certificate of Incorporation and By-Laws limit the monetary liability of directors to the Company and to its stockholders and provide for indemnification of the Company's officers and directors for liabilities and expenses that they may incur in such capacities. In general, officers and directors are indemnified with respect to actions taken in good faith in a manner reasonably believed to be in, or not opposed to, the best interests of the Company, and with respect to any criminal action or proceeding, actions that the indemnitee had no reasonable cause to believe were unlawful. The Company also has indemnification agreements with its directors and officers that provide for the maximum indemnification allowed by law. Reference is made to the form of Indemnification Agreement for Officers and Directors incorporated by reference as Exhibit 10.10 hereto. Thermo Electron Corporation has an insurance policy which insures the directors and officers of Thermo Electron and its subsidiaries, including the Company, against certain liabilities which might be incurred in connection with the performance of their duties. The Selling Securityholders are obligated under the Securities Purchase Agreements to indemnify Directors, officers and controlling persons of the Registrant against certain liabilities, including liabilities under the Securities Act. 19 PAGE Item 16. Exhibits. See the Exhibit Index included immediately preceding the exhibits to this Registration Statement. Item 17. Undertakings. (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the 20 PAGE Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) If the Registrant is a foreign private issuer, to file a post-effective amendment to the registration statement to include any financial statements required by Rule 3-19 of Regulation S-X at the start of any delayed offering or throughout a continuous offering. (b) The undersigned Registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom a prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such 21 PAGE indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. 22 PAGE SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements of filing on Form S-2, and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Waltham, Commonwealth of Massachusetts, on this 3rd day of April, 1996.
