                                     PART I


   Item 1. Business

   (a)  General Development of Business.

        Thermo Process Systems Inc. (the Company or the Registrant) provides a
   range of specialized environmental services. The Company provides
   environmental science and consulting services, laboratory-based testing,
   and nuclear health and safety services. These services were provided
   through the Company's Thermo Terra Tech joint venture prior to April 2,
   1995. Through the Company's majority-owned, publicly held Thermo
   Remediation Inc. (Thermo Remediation) subsidiary, the Company operates a
   network of soil-remediation centers that use thermal processing to remove
   and destroy petroleum contamination. Through its Thermo Fluids subsidiary,
   Thermo Remediation also collects and recycles used motor oil and provides
   services such as wastewater processing. As of April 1, 1995, the Company
   owned 66% of Thermo Remediation's common stock and holds a $2,650,000
   principal amount 3.875% subordinated convertible note due 2000 issued by
   Thermo Remediation, convertible into shares of Thermo Remediation common
   stock at a conversion price of $9.83 per share. The Company also provides
   equipment and services for the automated heat treating of metal parts.

        On February 6, 1995, the Company acquired all of the issued and
   outstanding capital stock of Engineering, Technology and Knowledge
   Corporation (ETKC). ETKC's sole subsidiary, Elson T. Killam Associates,
   Inc. (Killam Associates), is a leading provider of comprehensive
   environmental consulting and professional engineering services in selected
   areas of the United States.

        The Company's majority-owned Beheersmaatschappij J. Amerika N.V. (J.
   Amerika) subsidiary is a provider in the Netherlands of underground tank
   and other environmental services. On March 29, 1995, J. Amerika acquired
   the outstanding shares of Refining and Trading Holland B.V., which conducts
   business under the name North Refinery. North Refinery, located in
   Delfzijl, Holland, specializes in processing "off-spec" and contaminated
   petroleum fluids into usable products such as gas oil, diesel oil, and fuel
   oil. As a result of combining the businesses of J. Amerika and North
   Refinery, J. Amerika N.V. intends to change its name to Thermo EuroTech
   N.V. (Thermo EuroTech). As of April 1, 1995, the Company owned 62% of the
   outstanding common stock of J. Amerika.

        Effective April 2, 1995, the Company agreed to dissolve the Thermo
   Terra Tech joint venture and to purchase the businesses formerly operated
   by the joint venture from Thermo Instrument Systems Inc. (Thermo
   Instrument) for $34.3 million in cash. To finance this transaction, the
   Company issued to Thermo Electron a $35.0 million promissory note that
   bears interest at the Commercial Paper Composite Rate plus 25 basis points
   and is due May 13, 1997.

        On May 10, 1995, the Company acquired substantially all of the assets
   of Lancaster Laboratories, Inc. and its affiliate Clewmark Holdings
   (collectively Lancaster Laboratories) for $16.8 million in cash, plus the
   assumption of $5.4 million in bank indebtedness existing as of the close of
   acquisition. The purchase price is subject to a post-closing adjustment.
   Lancaster Laboratories, based in Lancaster, Pennsylvania, is a provider of
                                        2PAGE
<PAGE>

   high-quality analytical services to the environmental, food, and
   pharmaceutical industries.

        The Company was incorporated on May 30, 1986, as an indirect, wholly
   owned subsidiary of Thermo Electron Corporation (Thermo Electron). Prior to
   its incorporation, the Company's operations were conducted by two wholly
   owned subsidiaries of Thermo Electron. As of April 1, 1995, Thermo Electron
   owned 13,933,591 shares of the common stock of the Company, representing
   80% of such stock then outstanding. Thermo Electron is a world leader in
   environmental monitoring and analysis instruments and a manufacturer of
   biomedical products including heart-assist systems and mammography systems,
   papermaking and recycling equipment, alternative-energy systems, and other
   specialized products. Thermo Electron also conducts advanced technology
   research and development.

        Thermo Electron intends, for the foreseeable future, to maintain at
   least 50% ownership of the Company. During fiscal 19951, Thermo Electron
   purchased 794,430 shares of the Company's common stock in the open market
   at a total price of $6,466,000.

   (b)  Financial Information About Industry Segments.

        The Company conducts business in the environmental services industry
   segment. The Company provides environmental science and engineering
   services, laboratory-based testing, and nuclear health and safety services.
   The Company also provides environmental services for the remediation and
   testing of petroleum-contaminated soils and groundwater and for
   waste-fluids recycling, as well as specialized metallurgical-processing
   services. In addition, the Company designs, manufactures, and installs
   advanced custom-engineered thermal-processing systems used in manufacturing
   to impart desirable metallurgical properties, such as added tensile
   strength and wear resistance, into treated parts.

   (c)  Description of Business.

        (i) Principal Products and Services

   Environmental Analysis and Field Services

        The Company provides two broad types of environmental analysis and
   field services: environmental and radiochemical analysis, and environmental
   science and consulting services.

        Environmental and Radiochemical Analysis Services. Through a network
        of facilities in the United States, the Company provides comprehensive
        laboratory-based environmental testing, analysis, and related services
        to detect and measure hazardous wastes and radioactive materials. Each
        of the laboratories in the Company's network has developed
        specializations, and samples obtained by one laboratory can be shipped
        to the specialists in the network for analysis, enabling the network
        to provide a full complement of analytical and testing services.

        Analytical laboratory services consist of a comprehensive range of
        analytical tests to detect and measure organic contaminants, inorganic
        contaminants, and radioactive materials in samples of soil, water,
        air, industrial wastes, and biological materials. In addition, the

   1 References to fiscal 1995, 1994, and 1993 herein are for the fiscal
     years ended April 1, 1995, April 2, 1994, and April 3, 1993,
     respectively.
                                        3PAGE
<PAGE>

        Company's analytical laboratories have the capability to analyze
        "mixed wastes," which are hazardous wastes that also are radioactive.
        The handling of mixed wastes requires special testing procedures and
        facilities, including a license from the Nuclear Regulatory Commission
        or its designees to accept shipments of such materials. The Company
        also has established detailed procedures and strict operating
        standards to ensure consistent performance and to allow it to
        participate in the Environmental Protection Agency's (EPA) Contract
        Laboratory Program (CLP). The EPA, through the CLP, solicits bids on a
        competitive basis from commercial laboratories to perform testing and
        analysis.

        The Company is a provider of radiation and nuclear health physics
        services, including site surveys for radioactive materials, on-site
        samples and analysis in support of decontamination programs, and
        dosimetry services to measure personnel exposure. As part of its
        on-site services, Company personnel usually perform a preliminary
        survey using portable radiation-detection equipment. As a result of
        this survey, samples are taken at critical locations and are then
        analyzed radiometrically and radiochemically in a mobile laboratory
        facility at the site or at one of the Company's laboratories. This
        data is then used to plan cleanup operations. A substantial part of
        the Company's health physics services has been performed under the
        U.S. Department of Energy's (DOE) Formerly Utilized Sites Remedial
        Action Program and Surplus Facilities Management Program. The Company
        also supplies reusable thermoluminescent dosimeter badges. These
        badges, worn by personnel working in areas where radioactive material
        may be present, are periodically returned to the Company for
        processing to determine the level of radiation exposure.

        Environmental Science and Engineering Services. Environmental science
        services include the preparation of environmental impact studies,
        which are used to predict the environmental effects of a given
        activity. The Company provides these services through several offices
        located along the eastern seaboard of the United States. Typically,
        the Company's customers require an environmental study to meet the
        standards of a monitoring program or to obtain construction or
        operating permits. For example, the Company studies the impact of
        thermal pollution from nuclear power plants and the effects of
        hydroelectric power plant construction on fish populations. The
        Company also monitors soil around landfills for toxic contaminants,
        underground storage tanks, and ambient air conditions for siting and
        permit applications.

        In addition, the Company provides a wide range of environmental
        consulting services to private- and public-sector clients. These
        services include the design and inspection of water supply and
        wastewater treatment facilities; investigations of different methods
        to clean up hazardous waste sites; assistance in obtaining government
        permits; transportation-related and similar types of infrastructure
        engineering, survey, and land-use planning; and support services which
        include mechanical, electrical, and structural engineering.

        On February 6, 1995, the Company acquired all of the issued and
        outstanding capital stock of ETKC from Nord Est S.A. The purchase
        price for ETKC's stock was (a) $12.5 million in cash and (b) a zero
        coupon note, payable in February and May 1998, with a face value of
        $28 million and a present value of $22.3 million as of the acquisition
        closing date. The Company also exchanged certain outstanding options
                                        4PAGE
<PAGE>

        to purchase Killam Associates' stock for $1.9 million in cash and
        options to purchase the Company's common stock, which options were
        valued at $6.9 million. To help finance this acquisition, the Company
        issued to Thermo Electron a $38 million promissory note, due 1997.
        ETKC's sole subsidiary, Killam Associates, is a leading provider of
        comprehensive environmental consulting and professional engineering
        services in selected areas of the United States. Killam Associates is
        one of the most highly respected sources of expertise in areas related
        to the design, planning, and construction supervision of municipal and
        privately owned environmental facilities, including water treatment
        plants, waste treatment plants, and hazardous wastewater facilities.
        Killam Associates specializes in full-service contract operations to
        plant owners in the public and private sectors. These services
        facilitate regulatory compliance, optimize day-to-day plant
        operations, reduce costs, provide competent, experienced personnel,
        and promote good community relations. 

        The market for the Company's environmental analysis and field services
   results primarily from customers who need to comply with federal, state,
   and local regulations that relate to environmental protection, the
   management and treatment of hazardous wastes, and the need to upgrade and
   expand infrastructure in response to economic development. These customers
   typically rely on independent laboratories and environmental science and
   engineering consultants, such as the Company's, for ongoing analysis and
   monitoring of such wastes and direction for compliance with various
   environmental regulations.

        A substantial portion of the Company's analytical laboratory and
   environmental science services sales are made to existing customers on a
   repeat basis. Environmental science services are often performed as
   multiyear studies. In addition to federal, state, and local governments,
   customers include public utilities, consulting and construction engineers,
   waste management companies, oil refineries, mining companies, chemical
   manufacturers, architectural and engineering firms, and a variety of
   service companies involved with real estate transactions. The Company
   participates in industrial trade shows and technical conferences concerning
   pollution control, water quality, environmental management, specific
   cleanup efforts (e.g. Superfund), and industrial hygiene.

        During fiscal 1995, 1994, and 1993, the Company derived revenues of
   $70.9 million, $54.8 million, and $55.0 million, respectively, from
   environmental analysis and field services.

   Environmental Remediation Services

         The Company, through its majority-owned, publicly held Thermo
   Remediation subsidiary, operates a network of soil-remediation centers
   serving customers in more than a dozen states. Thermo Remediation's Thermo
   Fluids subsidiary collects and recycles used motor oil and provides
   services such as wastewater processing. In October 1994, Thermo Remediation
   acquired a soil-remediation facility in South Tacoma, Washington (renamed
   TPST Woodworth) from Woodworth & Company, Inc. for $4.7 million in cash. In
   December 1994, Thermo Remediation acquired a soil-remediation facility in
   Baltimore County, Maryland (renamed TPST Maryland) from the principals of
   Bryn Awel Corporation for $6.8 million in cash.

        At the Company's soil-remediation centers, soil is thermally treated
   to remove and destroy petroleum contamination caused by leaking underground
   storage tanks (USTs), aboveground storage tanks, spills, and other sources.
                                        5PAGE
<PAGE>

   The Company's soil-remediation centers are environmentally secure
   facilities for receiving, storing, and processing petroleum-contaminated
   soils. Each site consists principally of a soil-storage area and a
   soil-remediation unit (SRU). The Company maintains standards for acceptance
   of petroleum-contaminated soil. Information required by the Company prior
   to the acceptance of soil includes identification of the generator, the
   origin and nature of the contamination, and a complete site history. The
   Company requires a preacceptance analysis by environmental analytical
   testing laboratories to identify contaminants and their concentrations. In
   addition, the customer must certify that the soil is not "hazardous" as
   defined by EPA, state, or local regulations. The Company generates an
   individual manifest for each truckload of soil that meets the Company's
   acceptance criteria.

        The Company screens all soil prior to treatment to remove large
   nonprocessable materials such as glass, metal, rubber, paper, and stones.
   Screened soil is then loaded into the SRU's primary combustion chamber, a
   rotary kiln that heats the soil to temperatures ranging from approximately
   400 to 1,000 degrees Fahrenheit to volatilize petroleum contaminants from
   the soil. The volatilized petroleum gases pass from the rotary kiln into a
   secondary combustion chamber, where they are heated to temperatures ranging
   from 1,400 to 1,800 degrees Fahrenheit and are completely oxidized to form
   carbon dioxide and water vapor. After discharge from the SRU, clean soil is
   stored in piles and labeled and sampled for analysis by certified
   environmental laboratories. After receiving certification that the soil
   meets local cleanup standards, the soil is trucked off-site for a variety
   of uses, such as construction fill.

        The market for remediation of petroleum-contaminated soils, as with
   many other waste markets, was created by environmental regulations and
   economic concerns. The Company's customers include the major oil companies,
   public utilities, large industrial companies, the federal government
   including the military, and certain municipal governments and agencies.

        The Company and Thermo Electron entered into a development agreement
   under which Thermo Electron agreed to fund up to $4.0 million of the direct
   and indirect costs of the Company's development of soil-remediation
   centers. In exchange for this funding, the Company granted Thermo Electron
   a royalty equal to approximately 3% of net revenues from soil-remediation
   services performed at the centers developed under the agreement. The
   royalty payments may cease if the amounts paid by the Company yield a
   certain internal rate of return to Thermo Electron on the funds advanced to
   the Company under the agreement. The Company recorded contract revenues of
   $776,000 and $1,793,000 under the agreement for development costs expended
   in fiscal 1994 and 1993, respectively. As of October 2, 1993, funding under
   the agreement was complete. Two sites, Southern California and West Palm
   Beach, Florida, were developed under the agreement and the Company paid
   royalties of $432,000 in fiscal 1995, $351,000 in fiscal 1994, and $149,000
   in fiscal 1993 to Thermo Electron.

        The Company, through its Thermo Fluids subsidiary, collects, tests,
   processes, and recycles used motor oil and other industrial oils. In
   addition, the Company collects and recycles oily water and oil filters.
   Thermo Fluids has collection facilities located in Phoenix and Tucson,
   Arizona. From these sites, Thermo Fluids operates a fleet of oil and water 
   collection trucks to pick up waste oils and oily water. Outlying areas in
   Arizona are serviced from one of these two locations.

                                        6PAGE
<PAGE>

        The Company through its J. Amerika subsidiary provides environmental
   and underground tank services. J. Amerika, which is a provider in the
   Netherlands of services for remediating petroleum-contaminated groundwater,
   is seeking to expand its business to include the remediation of
   petroleum-contaminated soil, although to date the Company's efforts to
   secure the necessary operating permits have been unsuccessful.

        On March 29, 1995, J. Amerika acquired the outstanding shares of
   Refining and Trading Holland B.V., which conducts business under the name
   North Refinery, from Stalt Holding B.V. The purchase price for North
   Refinery's stock was 9.6 million Dutch guilders (approximately $6.2
   million) and 228,570 shares of J. Amerika's capital stock, valued at 1.3
   million Dutch guilders (approximately $0.9 million). North Refinery, a
   petroleum-fluids recycling operation, is located on 15 acres in Delfzijl,
   Holland and specializes in processing "off-spec" mixtures of oil that
   contain water, ash, and sediment into commercially tradable end products
   used in blending. The off-spec oil is filtered and centrifuged at elevated
   temperatures in preparation for distillation. Using a completely automated
   distillation system, the refinery has the capacity to process 120,000
   metric tons per year. Processing capacity depends on the pre-treatment
   requirements of the off-spec oil or chemical waste (feedstock) and as such
   depends on the quality of the feedstock most of which the refinery receives
   from Russian oil refineries. During the refining process, samples are
   continuously tested to monitor the quality of the process flow. After
   distillation, the resulting end product consists mainly of two commercially
   tradable products that are sold to blenders who incorporate them into
   commercial products. North Refinery also holds a chemical-waste permit for
   the processing of a special classification of oil-contaminated liquids.
   With the recent grant of this chemical-waste permit, North Refinery has
   started processing chemical waste stream products. The end product is light
   gas oil or heavy gas oil, which is used for fuel blending. Light gas oil is
   used in blending to make diesel fuels. Heavy gas oil is used in blending to
   make marine fuels or used as a feed material to catalytic cracker
   operations. The market for blending gas oils is very large and oils such as
   North Refinery's end products represent a very small percentage of the
   total market.

        During fiscal 1995, 1994, and 1993, the Company derived revenues,
   excluding related party development revenues discussed above, of $36.2
   million, $28.8 million, and $19.1 million, respectively, from its
   environmental remediation services.

   Metallurgical Services

        The Company provides a comprehensive range of metallurgical
   thermal-processing services at its facilities in Minnesota and California. 
   Metallurgical-processing services performed include hardening, annealing,
   stress relieving, normalizing, and tempering, and are performed over a
   range of temperatures and in controlled metallurgical atmospheres, as well
   as thermal treatment using induction hardening methods. Much of the work
   performed is specialized, requiring the treatment of complex parts without
   altering dimensions or other specifications or, in some cases, requiring
   the correction of dimensional differences. In many cases, the Company works
   with customers to develop specifications and methods for metallurgical
   processing of their products.

                                        7PAGE
<PAGE>

        During fiscal 1995, 1994, and 1993, the Company derived revenues of
   $12.3 million, $10.8 million, and $12.2 million, respectively, from its
   metallurgical services.

   Process Systems
  
        The Company's thermal-processing furnaces include a wide variety of
   systems such as continuous, controlled-atmosphere furnace systems and batch
   furnace systems. The Company's customers use these systems in high-volume
   manufacturing operations such as those employed in the automotive and
   heavy-equipment industries. The Company's proprietary multi-chamber
   carburizing systems allow users to regulate temperature and carbon
   atmosphere requirements with high precision and repeatability, resulting in
   a more efficient process and higher quality, more uniform parts.

        The Company's products also include integral-quench batch furnaces
   with automated materials-handling systems and process monitoring and
   control systems that incorporate proprietary software, sensors,
   programmable logic controllers, and other instruments to monitor operating
   parameters and to control furnace functions. In addition, the Company
   supplies vacuum furnaces, including conventional two- and six-bar single
   chamber systems. Heat processing in a vacuum eliminates the detrimental
   effects of contaminating gases, such as oxygen, which can cause corrosion
   and surface defects in processed parts. Vacuum processing and related
   technologies have applications in many industries, but especially in the
   manufacture of automotive components, aerospace and electronics components,
   and medical implants.

        During fiscal 1995, 1994, and 1993, the Company derived revenues of
   $14.4 million, $15.0 million, and $16.9 million, respectively, from its
   process systems.

        (ii) New Products
 
        The Company has made no commitments to new products that would require
   the investment of a material amount of the Company's assets.

        (iii) Raw Materials

        The feedstock used by North Refinery has historically been obtained
   from Russian oil refineries through traders located in Moscow. In fiscal
   1994, prior to its acquisition by the Company, North Refinery experienced
   an interruption of the Russian oil supply which adversely affected its
   business. North Refinery is concentrating on moving its dependence upon
   Russian oil to other sources of chemical waste and non-Russian oil.

        The principal materials used by the Company in its manufacturing
   operations are fabricated steel, alloy castings, and ceramic and insulating
   refractory materials. To date, the Company has not experienced any
   difficulty in obtaining any of the materials or components used in its
   operations and does not foresee any such difficulty in the future. The
   Company has multiple sources for all of its significant raw material needs.

        (iv) Patents, Licenses, and Trademarks

        The Company currently owns a number of U.S. patents. Although the
   Company believes that patent protection provides it with competitive
   advantages with respect to certain portions of its business and will
   continue to seek patent protection when appropriate, the Company also
   believes that its business depends primarily upon trade secrets and the
   technical and marketing expertise of its personnel.

        The Company has acquired specialized furnace technology to braze, or
   fuse, aluminum through an exclusive cross-license arrangement with a
   British firm, Camlaw Ltd. (Camlaw). Under the agreement, the Company will
   pay Camlaw a royalty of between 5% and 10% of net sales of aluminum-brazing
   furnaces. Camlaw, in turn, has agreed to a similar royalty arrangement on
   any sales of furnaces in the U.K. employing the Company's
   continuous-atmosphere pusher technology.

        (v) Seasonal Influences

        While the Company conducts significant operations year-round, several
   of its soil-remediation centers, particularly in Oregon, Virginia,
   Washington, and Maryland, experience seasonal fluctuations in their
   remediation activity due to a reduction in soil excavations during winter
   months. In Europe, North Refinery may also experience a decline in the
   feedstock delivered to its facilities during winter months, due to frozen
   waterways. Certain environmental testing services, such as field sampling,
   may decline in winter months. Such seasonal influences may have a material
   effect on the Company's revenues.

        (vi) Working Capital Requirements

        In general, there are no special inventory requirements or credit
   terms extended to customers that would have a material adverse effect on
   the Company's working capital.

        (vii) Dependency on a Single Customer

        The Company derived 6%, 16%, and 17% of its total revenues in fiscal
   1995, 1994, and 1993, respectively, from contracts or subcontracts with the
   federal government.

        (viii) Backlog

        The backlog of firm orders for the Company's environmental analysis
   and field services was $66,228,000 and $32,225,000 as of April 1, 1995 and
   April 2, 1994, respectively. Environmental remediation and metallurgical
   services are provided on a current basis pursuant to purchase orders.
   Accordingly, there is no backlog for these services. The backlog of firm
   orders for the Company's process systems products was $4,361,000 and
   $3,536,000 as of April 1, 1995 and April 2, 1994, respectively. The process
   systems backlog includes the uncompleted portion of equipment contracts
   that are accounted for using the percentage-of-completion method. Of the
   fiscal 1995 backlog amount, substantially all orders are expected to be
   filled within the current fiscal year.

                                        9PAGE
<PAGE>

        (ix) Government Contracts

        Approximately 6% of the Company's revenues in fiscal 1995 was derived
   from contracts or subcontracts with the federal government that are subject
   to renegotiation of profits or termination. The Company does not have any
   knowledge of threatened or pending renegotiation or termination of any
   material contract or subcontract.

        (x) Competition

   Environmental Analysis and Field Services

        Hundreds of independent analytical testing laboratories and consulting
   firms compete for environmental services business nationwide. Many of these
   firms use equipment and processes similar to those of the Company.
   Competition is based not only on price, but also on reputation for
   accuracy, quality, and the ability to respond rapidly to customer
   requirements. In addition, many industrial companies have their own
   in-house analytical testing capabilities. The Company believes that its
   competitive strength lies in certain niche markets within which the Company
   is recognized for its expertise.

        The Company's newly acquired Killam Associates subsidiary is engaged
   in highly competitive markets in all of its service areas. In its
   geographic service area, competition consists of small one- to three-person
   firms offering limited scope of services, as well as much larger firms that
   may be regional, national, or international in the scope of services they
   offer. The principal competitive factors for the Company are: reputation;
   experience; breadth and quality of services offered; and technical,
   managerial, and business proficiency.

   Environmental Remediation Services

        The Company believes that there are two other companies that operate
   fixed-site thermal-treatment facilities for soil remediation in multiple
   states. However, several large waste management companies are analyzing
   this market and may compete with the Company in the future. As a
   consequence of the Company's strategy and customer base, the Company's
   current competition is primarily from other fixed-site thermal-treatment
   facilities and from landfills. However, the market for
   petroleum-contaminated soil-processing services is highly fragmented and
   the Company also competes with operators of mobile thermal-treatment
   facilities, bioremediation and vapor-extraction technologies and, in
   certain states, with asphalt plants and brick kilns that use the
   contaminated soil in their production processes. The Company competes
   primarily based on its ability to offer its customers superior protection
   from environmental liabilities. Many of the Company's largest customers,
   such as the major oil companies, are extremely sensitive to environmental
   liability and therefore conduct thorough environmental audits of
   soil-treatment facilities before qualifying them as approved facilities.

                                       10PAGE
<PAGE>

   These approvals constitute an important barrier to entry into this segment
   of the soil-remediation market. Although the Company typically prices its
   services at a premium over landfills and other treatment technologies,
   competitive conditions limit the prices charged by the Company in each
   local market. Pricing is therefore a major competitive factor for the
   Company.

        Thermo Fluids operates the largest fleet of collection vehicles in
   Arizona. Thermo Fluids competes with numerous smaller and several larger
   collection companies in its current market.

        North Refinery faces competition for Russian oil from some small
   companies, major oil companies, Russian refineries, and a company with a
   similar distillation technology in Italy. It is the Company's strategy to
   reduce dependence on the Russian oil business by making the transition to
   process other sources of oil and chemical waste. The market for blending
   gas oils is very large and oils such as North Refinery's end products
   represent a very small percentage of the total market. 

   Metallurgical Services

        The market for metallurgical services is typically regional and very
   competitive. Both regions in which the Company has facilities contain
   numerous competitors. In addition, in-house heat-treating facilities
   provide a major source of competition. The Company competes in this segment
   on the basis of services provided, turnaround time, and price.

   Process Systems

        The market for thermal-processing systems is subject to intense
   competition worldwide. The Company is aware of at least eight companies
   that market a number of products comparable to the Company's, but
   competition for particular projects is typically limited to fewer
   companies. The Company competes on the basis of several factors, including
   technical performance, product quality and reliability, timely delivery,
   and often price. Certain products sold by the Company's competitors are
   less expensive than comparable products sold by the Company.

        (xi) Environmental Protection Regulations

        The Company believes that compliance by the Company with federal,
   state, and local environmental protection regulations will not have a
   material adverse effect on its capital expenditures, earnings, or
   competitive position.

        (xii) Number of Employees


        At April 1, 1995, the Company employed 1,609 persons.

   (d)  Financial Information About Exports by Domestic Operations and About
        Foreign Operations.
        

        The Company's exports by domestic operations and foreign operations
   are currently insignificant.

   (e)  Executive Officers of the Registrant.
      

                                Present Title
   Name                    Age  (Year First Became Executive Officer)
   ----------------------  ---  --------------------------------------------

   Dr. John P. Appleton    60   President and Chief Executive Officer (1993)
   John N. Hatsopoulos     60   Vice President and Chief Financial Officer
                                 (1988)
   Jeffrey L. Powell       36   Vice President (1994)
   Bruce J. Taunt          44   Vice President, Finance and Administration 
                                (1994)
   Paul F. Kelleher        52   Chief Accounting Officer (1986)

        Each executive officer serves until his successor is chosen or
   appointed by the Board of Directors and qualified or until earlier
   resignation, death, or removal. All executive officers except Dr. Appleton,
   Mr. Powell, and Mr. Taunt have held comparable positions for at least five
   years, either with the Company or with its parent company, Thermo Electron.
   Dr. Appleton has served as a Vice President of Thermo Electron since 1975
   in various managerial capacities. Mr. Powell has been President and Chief
   Operating Officer of Thermo Remediation since December 1991. From March
   1989 until January 1991, Mr. Powell was Vice President, Sales and
   Marketing, of Thermo Remediation and from January 1991 through December
   1991 was President of Thermo Remediation. Mr. Taunt has been Vice President
   of Finance and Administration since 1992. Prior to joining the Company, Mr.
   Taunt was Vice President and Controller of the Cross Company, a subsidiary
   of Cross and Trecker. Messrs. Hatsopoulos and Kelleher are full-time
   employees of Thermo Electron, but devote such time to the affairs of the
   Company as the Company's needs reasonably require.


   Item 2. Properties
          
        The location and general character of the Company's principal
   properties as of April 1, 1995, are as follows:

        The Company owns approximately 369,000 square feet of office,
   engineering, laboratory, production, and manufacturing space, principally
   in the Netherlands, Minnesota, New Jersey, California, and New Mexico, and
   leases approximately 810,000 square feet of office, engineering,
   laboratory, production, and manufacturing space under leases expiring from
   fiscal 1995 to 2008, principally in California, Michigan, Massachusetts,
   New Hampshire, New Jersey, New Mexico, New York, and Vermont. The Company
   also owns approximately 10 acres in Adelanto, California, approximately
   four acres in West Palm Beach, Florida, approximately four acres in
   Portland, Oregon, approximately 20 acres in Columbia, South Carolina, and
   approximately 63 acres in Baltimore County, Maryland, from which it
   provides soil-remediation services. The Company occupies approximately one
   acre in Greenville, South Carolina, pursuant to a lease that expires in
   1997, from which it provides soil-remediation services. The Company
   operates its SRU on approximately two and one-half acres in Chester,
   Virginia, pursuant to an agreement that expires in 1998, but which can be
   terminated by the Company at an earlier date. The Company occupies
   approximately five acres from which it provides soil-remediation services
   in Tacoma, Washington, pursuant to a lease that expires in 2004. Thermo
   Fluids occupies an aggregate of approximately eight acres on two sites in
   Arizona, consisting of office space, fluids-recycling and maintenance
   facilities, and sites for fluids storage tanks. North Refinery occupies

                                       12PAGE
<PAGE>




   approximately 15 acres in Delfzijl, Holland, consisting of office space,
   distillation facilities, and oil storage tanks, pursuant to a lease that
   expires in 2059.

        The Company believes that these facilities are in good condition and
   are adequate for its present operations and that other suitable space is
   readily available if any of such leases are not extended.


   Item 3. Legal Proceedings
 
        The Company has been notified that the EPA has determined that a
   release or a substantial threat of a release of a hazardous substance, as
   defined in the Comprehensive Environmental Response Compensation and
   Liability Act of 1980 (CERCLA) occurred at several sites to which chemical
   or other wastes generated by the manufacturing operations of the Company
   were sent. These notifications allege that the Company may be a potentially
   responsible party with respect to the remedial actions needed to control or
   clean up any such releases. Under CERCLA, responsible parties can include
   current and previous owners of the site, generators of hazardous substances
   disposed of at the site, and transporters of hazardous substances to the
   site. Each responsible party can be jointly and severally liable, without
   regard to fault or negligence, for all costs associated with the
   remediation of the site. In each instance the Company believes that it is
   only one of several companies which received such notification and who may
   likewise be held liable for any such remedial costs.

        The Company evaluates its potential liability as a responsible party
   for this environmental matter on an ongoing basis based upon factors such
   as the estimated remediation costs, the nature and duration of the
   Company's involvement with the site, the financial strength of other
   potentially responsible parties, and the availability of indemnification
   from previous owners of acquired businesses. Estimated liabilities are
   accrued in accordance with Statement of Financial Accounting Standards No.
   5, "Accounting for Contingencies." To date, the Company has not incurred
   any significant liability with respect to this site and the Company
   anticipates that future liabilities related to any site with which the
   Company is currently involved will not have a materially adverse effect on
   the Company's business, results of operations or financial condition.

        In January 1995, the Company, Thermo Remediation, and several third
   parties filed a lawsuit in federal district court in Delaware against
   Recycling Sciences International, Inc. (RSI) requesting a declaratory
   judgment that six U.S. patents owned by RSI are invalid and not infringed
   by Thermo Remediation's soil-remediation services and equipment, and asking
   the court to enjoin RSI from asserting any of these patents against the
   Company or Thermo Remediation. The suit follows continued allegations by
   RSI that Thermo Remediation's activities in treating petroleum-contaminated
   soil infringe a number of these patents and an offer of a non-exclusive
   patent license in return for payments which Thermo Remediation believes
   substantially exceed any value of a license. RSI filed an answer to the
   complaint in April 1995, and is attempting to change the forum of this
   litigation to the federal district court in Illinois. Although the Company
   agreed, in connection with the formation of Thermo Remediation, to
   indemnify and hold Thermo Remediation harmless against damages or other
   costs associated with any claims of infringement of intellectual property
   by the technology transferred by the Company to Thermo Remediation,
   including claims which may be made by RSI, there can be no assurance that
   RSI may not seek and obtain an injunction against the use of Thermo
                                       13PAGE
<PAGE>

   Remediation's technology to remediate petroleum-contaminated soil. The
   Company continues to believe that RSI's accusations are unfounded and that
   Thermo Remediation's activities do not infringe any valid claims of the
   patents.

                    Report of Independent Public Accountants
                    ----------------------------------------



   To the Shareholders and Board of Directors of
   Thermo Process Systems Inc.:


        We have audited in accordance with generally accepted auditing
   standards, the consolidated financial statements included in Thermo Process
   Systems Inc.'s Annual Report to Shareholders incorporated by reference in
   this Form 10-K, and have issued our report thereon dated May 9, 1995
   (except with respect to the matter discussed in Note 14 as to which the
   date is June 2, 1995). Our audits were made for the purpose of forming an
   opinion on those statements taken as a whole. The schedule listed in Item
   14 on page 16 is the responsibility of the Company's management and is
   presented for purposes of complying with the Securities and Exchange
   Commission's rules and is not part of the basic consolidated financial
   statements. This schedule has been subjected to the auditing procedures
   applied in the audits of the basic consolidated financial statements and,
   in our opinion, fairly states in all material respects the consolidated
   financial data required to be set forth therein in relation to the basic
   consolidated financial statements taken as a whole.

                           THERMO PROCESS SYSTEMS INC.

                           DIRECTORS STOCK OPTION PLAN

            (As amended and restated effective as of January 1, 1995)

   1.   Purpose
 
        The purpose of this Directors Stock Option Plan (the "Plan") of Thermo
   Process Systems Inc. (the "Company") is to encourage ownership in the
   Company by non-management Directors of the Company whose services are
   considered essential to the Company's growth and progress and to provide
   them with a further incentive to become Directors and to continue as
   Directors of the Company. The Plan is intended to be a nonstatutory stock
   option plan.

   2.   Administration

        The Board of Directors, or a Committee (the "Committee") consisting of
   two or more Directors of the Company appointed by the Board of Directors,
   shall supervise and administer the Plan. Grants of stock options under the
   Plan and the amount and nature of the options to be granted shall be
   automatic in accordance with Section 5. However, all questions of
   interpretation of the Plan or of any stock options granted under it shall
   be determined by the Board of Directors or the Committee and such
   determination shall be final and binding upon all persons having an
   interest in the Plan.

   3.   Participation in the Plan

        Directors of the Company who are not employees of the Company or any
   subsidiary or parent of the Company shall be eligible to participate in the
   Plan.

   4.   Stock Subject to the Plan

        The maximum number of shares which may be issued under the Plan shall
   be seventy-five thousand (75,000) shares of the Company's $.10 par value
   Common Stock (the "Common Stock") and twenty-five thousand (25,000) shares
   of the common stock of each Spinout Subsidiary (as defined in Section 5(B))
   as of the date of the Annual Meeting of Stockholders on which options to
   purchase such common stock are first granted to eligible Directors as
   provided in Section 5(B), each subject to adjustment as provided in Section
   9. Shares to be issued upon the exercise of options granted under the Plan
   may be either authorized but unissued shares or shares held by the Company
   in its treasury. If any option expires or terminates for any reason without
   having been exercised in full, the unpurchased shares subject thereto shall
   again be available for options thereafter to be granted.

   5.   Terms and Conditions

        A. Annual Stock Option Grants.

        Each Director of the Company who meets the requirements of Section 3
   and who is holding office immediately following the Annual Meeting of
   Stockholders shall be granted an option to purchase 1,000 shares of the
   Common Stock of the Company at the close of business on the date of such
PAGE
<PAGE>

   Annual meeting. Options granted under this Subsection A shall be
   exercisable as to 100% of the shares subject to the option as set forth in
   Section 5(C)(1), but shares acquired upon exercise are subject to
   repurchase by the Company at the exercise price if an Optionee ceases to
   serve as a director of the Company, Thermo Electron Corporation or any
   subsidiary of Thermo Electron Corporation, prior to the first anniversary
   of the grant date, for any reason other than death or disability.

        B.  Subsidiary Stock Option Grants.

        Each Director of the Company who meets the requirements of Section 3
   and this Section 5(B), from time to time in accordance with this Section
   5(B), shall be granted an option to purchase shares of the common stock of
   each majority-owned subsidiary of the Company, the common stock of which
   shall have become publicly traded or a portion of which shall have been
   sold primarily to third parties in a private placement or other arms-length
   transaction (such transaction being referred to herein as a "Spinout
   Transaction", and such subsidiary being referred to herein as a "Spinout
   Subsidiary"), upon the following terms and conditions.

        Each eligible Director who is not a Director of the Spinout Subsidiary
   shall be granted an option to purchase 1,500 shares of common stock of the
   Spinout Subsidiary as of the close of business on the date of the Company's
   Annual Meeting of Stockholders that first occurs after the Spinout
   Transaction, and also as of the close of business on the date of every
   fifth Annual Meeting of Stockholders of the Company that occurs thereafter
   during the duration of this Plan. For purposes of this Section 5(B),
   options to purchase common stock of Thermo Remediation Inc., a majority
   owned subsidiary of the Corporation, shall first be granted as of the close
   of business on the date of the Company's 1995 Annual Meeting of
   Stockholders. 

        Options granted under this Section 5(B) shall vest and be exercisable
   as to 100% of the shares of common stock subject to the option on the
   fourth anniversary of the grant date of the option, unless, prior to such
   anniversary, the underlying common stock shall have been registered under
   Section 12 of the Securities and Exchange Act of 1934, as amended (referred
   to herein as "Section 12 Registration"). From and after 90 days after the
   effective date of Section 12 Registration, options granted hereunder shall
   be immediately exercisable as to 100% of the shares subject to the option,
   subject to the right of the Company to repurchase the shares at the
   exercise price in the event the Optionee ceases to serve as a director of
   the Company, or any subsidiary of the Company or Thermo Election during the
   option term. The right of the Company to so repurchase the shares shall
   lapse as to one-fourth of the shares granted on each of the first, second,
   third and fourth anniversaries of the grant date of the option, provided
   the Optionee has remained continuously a director of the Company, Thermo
   Electron or any subsidiary of Thermo Electron since the grant date. In all
   other respects, the option shall be subject to the general terms and
   conditions applicable to all option grants as set forth below in Section
   5(C), including the determination of the exercise price of such option.

        No Director, who is otherwise eligible under Section 3, shall be
   eligible under this Section 5(B) to receive grants of stock options in
   Spinout Subsidiaries, if such Director also serves as a director of such
   Spinout Subsidiary.

                                        2PAGE
<PAGE>

        In the event any subsidiary shall become a "Spinout Subsidiary" as
   defined herein, then there shall be immediately reserved for transfer
   hereunder, on the date options to purchase common stock of the Spinout
   Subsidiary are first granted to eligible Directors and without further
   action required by the Board of Directors or Stockholders of the Company,
   twenty-five thousand (25,000) shares of the common stock of such Spinout
   Subsidiary.

        C.  General Terms and Conditions Applicable to All Grants.

        1.  Except as otherwise provided in Section 5(B), options shall be
            exercisable at any time from and after the six-month anniversary
            of the grant date and prior to the date which is the earliest of:

            (a) three years after the grant date for options granted under
            Section 5(A) and five years after the grant date for options
            granted under Section 5(B), (b) three months after the later of
            the date (i) the Optionee either ceases to meet the requirements
            of Section 3 or (ii) otherwise ceases to serve as a director of
            the Company, Thermo Electron or any subsidiary of Thermo Electron
            (six months in the event the Optionee ceases to meet the
            requirements of this Subsection by reason of his death), or (c)  
            the date of dissolution or liquidation of the Company.

        2.  The exercise price at which Options are granted hereunder shall
            be the average of the closing prices reported by the national
            securities exchange on which the common stock is principally
            traded for the five trading days immediately preceding and
            including the date the option is granted or, if such security is
            not traded on an exchange, the average last reported sale price
            for the five-day period on the NASDAQ National Market List, or
            the average of the closing bid prices for the five-day period
            last quoted by an established quotation service for
            over-the-counter securities, or if none of the above shall apply,
            the last price paid for shares of the Common Stock by independent
            investors in a private placement; provided, however, that such
            exercise price per share shall not be lower than the par value
            per share or less than 50% of the fair market value of the Common
            Stock until such time as the Company elects to be subject to Rule
            16b-3 as amended by SEC Rel. No. 33-28869.

        3.   All options shall be evidenced by a written agreement
             substantially in such form as shall be approved by the Board of
             Directors or Committee, containing terms and conditions
             consistent with the provisions of this Plan.

   6.   Exercise of Options
      
        A.  Exercise/Consideration

        An option may be exercised in accordance with its terms by written
   notice of intent to exercise the option, specifying the number of shares of
   stock with respect to which the option is then being exercised. The notice
   shall be accompanied by payment in the form of cash or shares of the
   Company's Common Stock (the "Tendered Shares") with a then current market
   value equal to the exercise price of the shares to be purchased; provided,
   however, that such Tendered Shares shall have been acquired by the Director
   more than six months prior to the date of exercise (unless such requirement
                                        3PAGE
<PAGE>

   is waived in writing by the Company). Against such payment the Company
   shall deliver or cause to be delivered to the Director a certificate for
   the number of shares then being purchased, registered in the name of the
   Director or other person exercising the option. If any law or applicable
   regulation of the Securities and Exchange Commission or other body having
   jurisdiction in the premises shall require the Company or the Director to
   take any action in connection with shares being purchased upon exercise of
   the option, exercise of the option and delivery of the certificate or
   certificates for such shares shall be postponed until completion of the
   necessary action, which shall be taken at the Company's expense.

        B.  Tax Withholding

        The Board of Directors or Committee will have the right to require
   that the person exercising an option under the Plan remit to the Company an
   amount sufficient to satisfy applicable federal, state and local tax
   withholding requirements, or make other arrangements satisfactory to the
   Company with regard to such requirements, if any, prior to the delivery of
   any Common Stock. If and to the extent that such withholding is required,
   the Board of Directors or Committee may permit the person exercising an
   option under the Plan to elect at such time and in such manner as the Board
   of Directors or Committee may provide to have the Company hold back from
   the shares to be delivered, or to deliver to the Company, Common Stock
   having a value calculated to satisfy the withholding requirement.

   7.   Transferability

        Options shall not be transferable, otherwise than by will or the laws
   of descent and distribution or pursuant to a qualified domestic relations
   order as defined in the Internal Revenue Code or Title I of the Employee
   Retirement Income Security Act, or the rules thereunder ("Qualified
   Domestic Relations Order"). Options may be exercised during the life of the
   Optionee only by the Optionee or a transferee pursuant to a Qualified
   Domestic Relations Order.

   8.   Limitation of Rights to Continue as a Director

        Neither the Plan, nor the quantity of shares subject to options
   granted under the Plan, nor any other action taken pursuant to the Plan,
   shall constitute or be evidence of any agreement or understanding, express
   or implied, that the Company will retain a Director for any period of time,
   or at any particular rate of compensation.

   9.   Changes in Common Stock

        If the outstanding shares of Common Stock are increased, decreased or
   exchanged for a different number or kind of shares or other securities, or
   if additional shares or new or different shares or other securities are
   distributed with respect to such shares of Common Stock or other
   securities, through merger, consolidation, sale of all or substantially all
   of the assets of the Company, reorganization, recapitalization,
   reclassification, stock dividend, stock split, reverse stock split or other
   distribution with respect to such shares of Common Stock, or other
   securities, an appropriate proportionate adjustment may be made in the
   maximum number or kind of shares reserved for issuance under the Plan. No
   fractional shares will be issued under the Plan on account of any such
   adjustments.
                                        4PAGE
<PAGE>

   10.  Limitation of Rights in Option Stock
       
        The Optionees shall have no rights as stockholders in respect of
   shares as to which their options shall not have been exercised,
   certificates issued and delivered and payment as herein provided made in
   full, and shall have no rights with respect to such shares not expressly
   conferred by this Plan or the written agreement evidencing options granted
   hereunder.

   11.  Stock Reserved

        The Company shall at all times during the term of the options reserve
   and keep available such number of shares of the Common Stock as will be
   sufficient to permit the exercise in full of all options granted under this
   Plan and shall pay all other fees and expenses necessarily incurred by the
   Company in connection therewith.

   12.  Securities Laws Restrictions

        A.  Investment Representations.

        The Company may require any person to whom an option is granted, as a
   condition of exercising such option, to give written assurances in
   substance and form satisfactory to the Company to the effect that such
   person is acquiring the shares subject to the option for his or her own
   account for investment and not with any present intention of selling or
   otherwise distributing the same, and to such other effects as the Company
   deems necessary or appropriate in order to comply with federal and
   applicable state securities laws.

        B.  Compliance with Securities Laws.

        Each option shall be subject to the requirement that if, at any time,
   counsel to the Company shall determine that the listing, registration or
   qualification of the shares subject to such option upon any securities
   exchange or under any state or federal law, or the consent or approval of
   any governmental or regulatory body, or that the disclosure of non-public
   information or the satisfaction of any other condition is necessary as a
   condition of, or in connection with, the issuance or purchase of shares
   thereunder, such option may not be exercised, in whole or in part, unless
   such listing, registration, qualification, consent or approval, or
   satisfaction of such condition shall have been effected or obtained on
   conditions acceptable to the Board of Directors. Nothing herein shall be
   deemed to require the Company to apply for or to obtain such listing,
   registration or qualification, or to satisfy such condition.

   13.  Change in Control

        A.  Impact of Event

        In the event of a "Change in Control" as defined in Section 13(B), the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

            (a) Any stock options awarded under the Plan that were not
            previously exercisable and vested shall become fully exercisable
            and vested.
                                        5PAGE
<PAGE>

            (b) Shares purchased upon the exercise of options subject to
            restrictions and to the extent not fully vested, shall become
            fully vested and all such restrictions shall lapse so that shares
            issued pursuant to such options shall be free of restrictions.

        B.  Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company, or the beneficial owner of 25% or more of the outstanding
   common stock of Thermo Electron Corporation ("Thermo Electron"), without
   the prior approval of the Prior Directors of the Company or Thermo
   Electron, as the case may be, (ii) the failure of the Prior Directors to
   constitute a majority of the Board of the Company or of the Board of
   Directors of Thermo Electron, as the case may be, at any time within two
   years following any Electoral Event, or (iii) any other event that the
   Prior Directors shall determine constitutes an effective change in the
   control of the Company or Thermo Electron. As used in the preceding
   sentence, the following capitalized terms shall have the respective
   meanings set forth below:

            (a) "Person" shall include any natural person, any entity, any
            "affiliate" of any such natural person or entity as such term is
            defined in Rule 405 under the Securities Act of 1933 and any
            "group" (within the meaning of such term in Rule 13d-5 under the
            Exchange Act);

            (b) "Prior Directors" shall mean the persons sitting on the
            Company's or Thermo Electron's Board of Directors, as the case
            may be, immediately prior to any Electoral Event (or, if there
            has been no Electoral Event, those persons sitting on the
            applicable Board of Directors on the date of this Agreement) and
            any future director of the Company or Thermo Electron who has
            been nominated or elected by a majority of the Prior Directors
            who are then members of the Board of Directors of the Company or
            Thermo Electron, as the case may be; and 

            (c) "Electoral Event" shall mean any contested election of
            Directors, or any tender or exchange offer for the Company's or
            Thermo Electron's Common Stock, not approved by the Prior
            Directors, by any Person other than the Company, Thermo Electron
            or a subsidiary of Thermo Electron.

   14.  Amendment of the Plan

        The provisions of Sections 3 and 5 of the Plan shall not be amended
   more than once every six months, other than to comport with changes in the
   Code, the Employee Retirement Income Security Act of 1974, or the rules
   thereunder. Subject to the foregoing, the Board of Directors may at any
   time, and from time to time, modify or amend the Plan in any respect,
   except that if at any time the approval of the Stockholders of the Company
   is required as to such modification or amendment under Rule 16b-3, the
   Board of Directors may not effect such modification or amendment without
   such approval.
                                        6PAGE
<PAGE>

        The termination or any modification or amendment of the Plan shall
   not, without the consent of an Optionee, affect his or her rights under an
   option previously granted to him or her. With the consent of the Optionees
   affected, the Board of Directors may amend outstanding option agreements in
   a manner not inconsistent with the Plan. The Board of Directors shall have
   the right to amend or modify the terms and provisions of the Plan and of
   any outstanding option to the extent necessary to ensure the qualification
   of the Plan under Rule 16b-3.

   15.  Effective Date of the Plan

        The Plan shall become effective on the date the Plan is approved by
   the stockholders of the Company.

                              EQUITY INCENTIVE PLAN


   1.   Purpose
  
        The purpose of this Equity Incentive Plan (the "Plan") is to secure
   for ThermoLase Corporation (the "Company") and its Stockholders the
   benefits arising from capital stock ownership by employees, officers and
   Directors of, and consultants to, the Company and its subsidiaries or other
   persons who are expected to make significant contributions to the future
   growth and success of the Company and its subsidiaries. The Plan is
   intended to accomplish these goals by enabling the Company to offer such
   persons equity-based interests, equity-based incentives or
   performance-based stock incentives in the Company, or any combination
   thereof ("Awards").

   2.   Administration

        The Plan will be administered by the Board of Directors of the Company
   (the "Board"). The Board shall have full power to interpret and administer
   the Plan, to prescribe, amend and rescind rules and regulations relating to
   the Plan and Awards, and full authority to select the persons to whom
   Awards will be granted ("Participants"), determine the type and amount of
   Awards to be granted to Participants (including any combination of Awards),
   determine the terms and conditions of Awards granted under the Plan
   (including terms and conditions relating to events of merger,
   consolidation, dissolution and liquidation, change of control, vesting,
   forfeiture, restrictions, dividends and interest, if any, on deferred
   amounts), waive compliance by a participant with any obligation to be
   performed by him or her under an Award, waive any term or condition of an
   Award, cancel an existing Award in whole or in part with the consent of a
   Participant, grant replacement Awards, accelerate the vesting or lapse of
   any restrictions of any Award and adopt the form of instruments evidencing
   Awards under the Plan and change such forms from time to time. Any
   interpretation by the Board of the terms and provisions of the Plan or any
   Award thereunder and the administration thereof, and all action taken by
   the Board, shall be final, binding and conclusive on all parties and any
   person claiming under or through any party. No Director shall be liable for
   any action or determination made in good faith. The Board may, to the full
   extent permitted by law, delegate any or all of its responsibilities under
   the Plan to a committee (the "Committee") appointed by the Board and
   consisting of two or more members of the Board, each of whom shall be
   deemed a "disinterested person" within the meaning of Rule 16b-3 (or any
   successor rule) of the Securities Exchange Act of 1934 (the "Exchange
   Act").

   3.   Effective Date
 

        The Plan shall be effective as of the date first approved by the Board
   of Directors, subject to the approval of the Plan by the Corporation's
   Stockholders. Grants of Awards under the Plan made prior to such approval
   shall be effective when made (unless otherwise specified by the Board at
   the time of grant), but shall be conditioned on and subject to such
   approval of the Plan.

   shares of the common stock, $.01 par value per share, of the Company (the
   "Common Stock"), reserved and available for distribution under the Plan
   shall be 500,000 shares. Such shares may consist, in whole or in part, of
   authorized and unissued shares or treasury shares.

        If any Award of shares of Common Stock requiring exercise by the
   Participant for delivery of such shares terminates without having been
   exercised in full, is forfeited or is otherwise terminated without a
   payment being made to the Participant in the form of Common Stock, or if
   any shares of Common Stock subject to restrictions are repurchased by the
   Company pursuant to the terms of any Award or are otherwise reacquired by
   the Company to satisfy obligations arising by virtue of any Award, such
   shares shall be available for distribution in connection with future Awards
   under the Plan.

   5.   Eligibility

        Employees, officers and Directors of, and consultants to, the Company
   and its subsidiaries, or other persons who are expected to make significant
   contributions to the future growth and success of the Company and its
   subsidiaries shall be eligible to receive Awards under the Plan. The Board,
   or other appropriate committee or person to the extent permitted pursuant
   to the last sentence of Section 2, shall from time to time select from
   among such eligible persons those who will receive Awards under the Plan.

   6.   Types of Awards

        The Board may offer Awards under the Plan in any form of equity-based
   interest, equity-based incentive or performance-based stock incentive in
   Common Stock of the Company or any combination thereof. The type, terms and
   conditions and restrictions of an Award shall be determined by the Board at
   the time such Award is made to a Participant; provided however that the
   maximum number of shares permitted to be granted under any Award or
   combination of Awards to any Participant during any one calendar year  may
   not exceed 5% of the shares of Common Stock outstanding at the beginning of
   such calendar year.

        An Award shall be made at the time specified by the Board and shall be
   subject to such conditions or restrictions as may be imposed by the Board
   and shall conform to the general rules applicable under the Plan as well as
   any special rules then applicable under federal tax laws or regulations or
   the federal securities laws relating to the type of Award granted.

        Without limiting the foregoing, Awards may take the following forms
   and shall be subject to the following rules and conditions:

        6.1  Options

        An option is an Award that entitles the holder on exercise thereof to
   purchase Common Stock at a specified exercise price. Options granted under
   the Plan may be either incentive stock options ("incentive stock options")
   that meet the requirements of Section 422 of the Internal Revenue Code of
   1986, as amended (the "Code"), or options that are not intended to meet the
   requirements of Section 422 ("non-statutory options").
                                        2PAGE
<PAGE>

        6.1.1  Option Price. The price at which Common Stock may be purchased
   upon exercise of an option shall be determined by the Board, provided
   however, the exercise price shall not be less than the par value per share
   of Common Stock.  

        6.1.2  Option Grants. The granting of an option shall take place at
   the time specified by the Board. Options shall be evidenced by option
   agreements. Such agreements shall conform to the requirements of the Plan,
   and may contain such other provisions (including but not limited to vesting
   and forfeiture provisions, acceleration, change of control, protection in
   the event of merger, consolidations, dissolutions and liquidations) as the
   Board shall deem advisable. Option agreements shall expressly state whether
   an option grant is intended to qualify as an incentive stock option or
   non-statutory option.

        6.1.3 Option Period. An option will become exercisable at such time or
   times (which may be immediately or in such installments as the Board shall
   determine) and on such terms and conditions as the Board shall specify.
   The option agreements shall specify the terms and conditions applicable in
   the event of an option holder's termination of employment during the
   option's term.

        Any exercise of an option must be in writing, signed by the proper
   person and delivered or mailed to the Company, accompanied by (1) any
   additional documents required by the Board and (2) payment in full in
   accordance with Section 6.1.4 for the number of shares for which the option
   is exercised.

        6.1.4  Payment of Exercise Price. Stock purchased on exercise of an
   option shall be paid for as follows: (1) in cash or by check (subject to
   such guidelines as the Company may establish for this purpose), bank draft
   or money order payable to the order of the Company or (2) if so permitted
   by the instrument evidencing the option (or in the case of a non-statutory
   option, by the Board at or after grant of the option), (i) through the
   delivery of shares of Common Stock that have been outstanding for at least
   six months (unless the Board expressly approves a shorter period) and that
   have a fair market value (determined in accordance with procedures
   prescribed by the Board) equal to the exercise price, (ii) by delivery of a
   promissory note of the option holder to the Company, payable on such terms
   as are specified by the Board, (iii) by delivery of an unconditional and
   irrevocable undertaking by a broker to deliver promptly to the Company
   sufficient funds to pay the exercise price, or (iv) by any combination of
   the permissible forms of payment.

        6.1.5  Buyout Provision. The Board may at any time offer to buy out
   for a payment in cash, shares of Common Stock, deferred stock or restricted
   stock, an option previously granted, based on such terms and conditions as
   the Board shall establish and communicate to the option holder at the time
   that such offer is made.

        6.1.6  Special Rules for Incentive Stock Options. Each provision of
   the Plan and each option agreement evidencing an incentive stock option
   shall be construed so that each incentive stock option shall be an
   incentive stock option as defined in Section 422A of the Code or any
   statutory provision that may replace such Section, and any provisions
   thereof that cannot be so construed shall be disregarded. Instruments
   evidencing incentive stock options must contain such provisions as are
   required under applicable provisions of the Code. Incentive stock options
                                        3PAGE
<PAGE>

   may be granted only to employees of the Company and its subsidiaries. The
   exercise price of an incentive stock option shall not be less than 100%
   (110% in the case of an incentive stock option granted to a more than ten
   percent Stockholder of the Company) of the fair market value of the Common
   Stock on the date of grant, as determined by the Board. An incentive stock
   option may not be granted after the tenth anniversary of the date on which
   the Plan was adopted by the Board and the latest date on which an incentive
   stock option may be exercised shall be the tenth anniversary (fifth
   anniversary, in the case of any incentive stock option granted to a more
   than ten percent Stockholder of the Company) of the date of grant, as
   determined by the Board.

        6.2  Restricted and Unrestricted Stock

        An Award of restricted stock entitles the recipient thereof to acquire
   shares of Common Stock upon payment of the purchase price subject to
   restrictions specified in the instrument evidencing the Award.

        6.2.1  Restricted Stock Awards. Awards of restricted stock shall be
   evidenced by restricted stock agreements. Such agreements shall conform to
   the requirements of the Plan, and may contain such other provisions
   (including restriction and forfeiture provisions, change of control,
   protection in the event of mergers, consolidations, dissolutions and
   liquidations) as the Board shall deem advisable.

        6.2.2  Restrictions. Until the restrictions specified in a restricted
   stock agreement shall lapse, restricted stock may not be sold, assigned,
   transferred, pledged or otherwise encumbered or disposed of, and upon
   certain conditions specified in the restricted stock agreement, must be
   resold to the Company for the price, if any, specified in such agreement.
   The restrictions shall lapse at such time or times, and on such conditions,
   as the Board may specify. The Board may at any time accelerate the time at
   which the restrictions on all or any part of the shares shall lapse.

        6.2.3  Rights as a Stockholder. A Participant who acquires shares of
   restricted stock will have all of the rights of a Stockholder with respect
   to such shares including the right to receive dividends and to vote such
   shares. Unless the Board otherwise determines, certificates evidencing
   shares of restricted stock will remain in the possession of the Company
   until such shares are free of all restrictions under the Plan.

        6.2.4  Purchase Price. The purchase price of shares of restricted
   stock shall be determined by the Board, in its sole discretion, but such
   price may not be less than the par value of such shares.

        6.2.5  Other Awards Settled With Restricted Stock. The Board may
   provide that any or all the Common Stock delivered pursuant to an Award
   will be restricted stock.

        6.2.6  Unrestricted Stock. The Board may, in its sole discretion, sell
   to any Participant shares of Common Stock free of restrictions under the
   Plan for a price determined by the Board, but which may not be less than
   the par value per share of the Common Stock.

        6.3  Deferred Stock
  
        6.3.1  Deferred Stock Award. A deferred stock Award entitles the
   recipient to receive shares of deferred stock which is Common Stock to be
                                        4PAGE
<PAGE>

   delivered in the future. Delivery of the Common Stock will take place at
   such time or times, and on such conditions, as the Board may specify. The
   Board may at any time accelerate the time at which delivery of all or any
   part of the Common Stock will take place.

        6.3.2  Other Awards Settled with Deferred Stock. The Board may, at the
   time any Award described in this Section 6 is granted, provide that, at the
   time Common Stock would otherwise be delivered pursuant to the Award, the
   Participant will instead receive an instrument evidencing the right to
   future delivery of deferred stock.

        6.4  Performance Awards

        6.4.1  Performance Awards. A performance Award entitles the recipient
   to receive, without payment, an Amount, in cash or Common Stock or a
   combination thereof (such form to be determined by the Board), following
   the attainment of performance goals. Performance goals may be related to
   personal performance, corporate performance, departmental performance or
   any other category of performance deemed by the Board to be important to
   the success of the Company. The Board will determine the performance goals,
   the period or periods during which performance is to be measured and all
   other terms and conditions applicable to the Award.

        6.4.2  Other Awards Subject to Performance Conditions. The Board may,
   at the time any Award described in this Section 6 is granted, impose the
   condition (in addition to any conditions specified or authorized in this
   Section 6 of the Plan) that performance goals be met prior to the
   Participant's realization of any payment or benefit under the Award.

   7.   Purchase Price and Payment

        Except as otherwise provided in the Plan, the purchase price of Common
   Stock to be acquired pursuant to an Award shall be the price determined by
   the Board, provided that such price shall not be less than the par value of
   the Common Stock. Except as otherwise provided in the Plan, the Board may
   determine the method of payment of the exercise price or purchase price of
   an Award granted under the Plan and the form of payment. The Board may
   determine that all or any part of the purchase price of Common Stock
   pursuant to an Award has been satisfied by past services rendered by the
   Participant. The Board may agree at any time, upon request of the
   Participant, to defer the date on which any payment under an Award will be
   made.

   8.   Loans and Supplemental Grants

        The Company may make a loan to a Participant, either on or after the
   grant to the Participant of any Award, in connection with the purchase of
   Common Stock under the Award or with the payment of any obligation incurred
   or recognized as a result of the Award. The Board will have full authority
   to decide whether the loan is to be secured or unsecured or with or without
   recourse against the borrower, the terms on which the loan is to be repaid
   and the conditions, if any, under which it may be forgiven.

        In connection with any Award, the Board may at the time such Award is
   made or at a later date, provide for and make a cash payment to the
   participant not to exceed an amount equal to (a) the amount of any federal,
   state and local income tax or ordinary income for which the Participant
   will be liable with respect to the Award, plus (b) an additional amount on
                                        5PAGE
<PAGE>

   a grossed-up basis necessary to make him or her whole after tax,
   discharging all the participant's income tax liabilities arising from all
   payments under the Plan.

   9.   Change in Control

        9.1  Impact of Event

        In the event of a "Change in Control" as defined in Section 9.2, the
   following provisions shall apply, unless the agreement evidencing the Award
   otherwise provides:

        (a) Any stock options or other stock-based Awards awarded under the
        Plan that were not previously exercisable and vested shall become
        fully exercisable and vested.

        (b) Awards of restricted stock and other stock-based Awards subject to
        restrictions and to the extent not fully vested, shall become fully
        vested and all such restrictions shall lapse so that shares issued
        pursuant to such Awards shall be free of restrictions.

        (c) Deferral limitations and conditions that relate solely to the
        passage of time, continued employment or affiliation, will be waived
        and removed as to deferred stock Awards and performance Awards.
        Performance of other conditions (other than conditions relating solely
        to the passage of time, continued employment or affiliation) will
        continue to apply unless otherwise provided in the agreement
        evidencing the Awards or in any other agreement between the
        Participant and the Company or unless otherwise agreed by the Board.

        9.2  Definition of "Change in Control"

        "Change in Control" means any one of the following events:  (i) when,
   any Person is or becomes the beneficial owner (as defined in Section 13(d)
   of the Exchange Act and the Rules and Regulations thereunder), together
   with all Affiliates and Associates (as such terms are used in Rule 12b-2 of
   the General Rules and Regulations of the Exchange Act) of such Person,
   directly or indirectly, of 50% or more of the outstanding Common Stock of
   the Company or its parent corporation, ThermoTrex Corporation
   ("ThermoTrex"), or the beneficial owner of 25% or more of the outstanding
   common stock of Thermo Electron Corporation ("Thermo Electron"), without
   the prior approval of the Prior Directors of the applicable issuer, (ii)
   the failure of the Prior Directors to constitute a majority of the Board of
   Directors of the Company, ThermoTrex or Thermo Electron, as the case may
   be, at any time within two years following any Electoral Event, or (iii)
   any other event that the Prior Directors shall determine constitutes an
   effective change in the control of the Company, ThermoTrex or Thermo
   Electron. As used in the preceding sentence, the following capitalized
   terms shall have the respective meanings set forth below:

        (a) "Person" shall include any natural person, any entity, any
        "affiliate" of any such natural person or entity as such term is
        defined in Rule 405 under the Securities Act of 1933 and any "group"
        (within the meaning of such term in Rule 13d-5 under the Exchange
        Act);

        (b) "Prior Directors" shall mean the persons sitting on the Company's,
        ThermoTrex' or Thermo Electron's Board of Directors, as the case may
                                        6PAGE
<PAGE>

        be, immediately prior to any Electoral Event (or, if there has been no
        Electoral Event, those persons sitting on the applicable Board of
        Directors on the date of this Agreement) and any future director of
        the Company, ThermoTrex or Thermo Electron who has been nominated or
        elected by a majority of the Prior Directors who are then members of
        the Board of Directors of the Company, ThermoTrex or Thermo Electron,
        as the case may be; and

        (c) "Electoral Event" shall mean any contested election of Directors,
        or any tender or exchange offer for the Company's, ThermoTrex' or
        Thermo Electron's Common Stock, not approved by the Prior Directors,
        by any Person other than the Company, ThermoTrex, Thermo Electron or a
        majority-owned subsidiary of Thermo Electron.

   10.  General Provisions

        10.1  Documentation of Awards

        Awards will be evidenced by written instruments, which may differ
   among Participants, prescribed by the Board from time to time. Such
   instruments may be in the form of agreements to be executed by both the
   Participant and the Company or certificates, letters or similar instruments
   which need not be executed by the participant but acceptance of which will
   evidence agreement to the terms thereof. Such instruments shall conform to
   the requirements of the Plan and may contain such other provisions
   (including provisions relating to events of merger, consolidation,
   dissolution and liquidations, change of control and restrictions affecting
   either the agreement or the Common Stock issued thereunder), as the Board
   deems advisable.

        10.2  Rights as a Stockholder

        Except as specifically provided by the Plan or the instrument
   evidencing the Award, the receipt of an Award will not give a Participant
   rights as a Stockholder with respect to any shares covered by an Award
   until the date of issue of a stock certificate to the participant for such
   shares.

        10.3  Conditions on Delivery of Stock

        The Company will not be obligated to deliver any shares of Common
   Stock pursuant to the Plan or to remove any restriction from shares
   previously delivered under the Plan (a) until all conditions of the Award
   have been satisfied or removed, (b) until, in the opinion of the Company's
   counsel, all applicable federal and state laws and regulations have been
   complied with, (c) if the outstanding Common Stock is at the time listed on
   any stock exchange, until the shares have been listed or authorized to be
   listed on such exchange upon official notice of issuance, and (d) until all
   other legal matters in connection with the issuance and delivery of such
   shares have been approved by the Company's counsel. If the sale of Common
   Stock has not been registered under the Securities Act of 1933, as amended,
   the Company may require, as a condition to exercise of the Award, such
   representations or agreements as counsel for the Company may consider
   appropriate to avoid violation of such act and may require that the
   certificates evidencing such Common Stock bear an appropriate legend
   restricting transfer.

                                        7PAGE
<PAGE>

        If an Award is exercised by the participant's legal representative,
   the Company will be under no obligation to deliver Common Stock pursuant to
   such exercise until the Company is satisfied as to the authority of such
   representative.

        10.4  Tax Withholding

        The Company will withhold from any cash payment made pursuant to an
   Award an amount sufficient to satisfy all federal, state and local
   withholding tax requirements (the "withholding requirements").

        In the case of an Award pursuant to which Common Stock may be
   delivered, the Board will have the right to require that the participant or
   other appropriate person remit to the Company an amount sufficient to
   satisfy the withholding requirements, or make other arrangements
   satisfactory to the Board with regard to such requirements, prior to the
   delivery of any Common Stock. If and to the extent that such withholding is
   required, the Board may permit the participant or such other person to
   elect at such time and in such manner as the Board provides to have the
   Company hold back from the shares to be delivered, or to deliver to the
   Company, Common Stock having a value calculated to satisfy the withholding
   requirement.

        10.5  Nontransferability of Awards

        Except as otherwise specifically provided by the Board in the case of
   participants who are not reporting persons under Section 16 of the Exchange
   Act, no Award (other than an Award in the form of an outright transfer of
   cash or Common Stock not subject to any restrictions) may be transferred
   other than by the laws of descent and distribution, except pursuant to the
   terms of a qualified domestic relations order as defined in the Code, and
   during a Participant's lifetime an Award requiring exercise may be
   exercised only by him or her (or in the event of incapacity, the person or
   persons properly appointed to act on his or her behalf).

        10.6  Adjustments in the Event of Certain Transactions

        (a) In the event of a stock dividend, stock split or combination of
   shares, recapitalization or other change in the Company's capitalization,
   or other distribution with respect to common Stockholders other than normal
   cash dividends, the Board will make (i) appropriate adjustments to the
   maximum number of shares that may be delivered under the Plan under Section
   4 above, and (ii) appropriate adjustments to the number and kind of shares
   of stock or securities subject to Awards then outstanding or subsequently
   granted, any exercise prices relating to Awards and any other provisions of
   Awards affected by such change.

        (b) The Board may also make appropriate adjustments to take into
   account material changes in law or in accounting practices or principles,
   mergers, consolidations, acquisitions, dispositions, repurchases or similar
   corporate transactions, or any other event, if it is determined by the
   Board that adjustments are appropriate to avoid distortion in the operation
   of the Plan, but no such adjustments other than those required by law may
   adversely affect the rights of any Participant (without the Participant's
   consent) under any Award previously granted.

                                        8PAGE
<PAGE>

        10.7  Employment Rights
 
        Neither the adoption of the Plan nor the grant of Awards will confer
   upon any person any right to continued employment with the Company or any
   subsidiary or interfere in any way with the right of the Company or
   subsidiary to terminate any employment relationship at any time or to
   increase or decrease the compensation of such person. Except as
   specifically provided by the Board in any particular case, the loss of
   existing or potential profit in Awards granted under the Plan will not
   constitute an element of damages in the event of termination of an
   employment relationship even if the termination is in violation of an
   obligation of the Company to the employee.

        Whether an authorized leave of absence, or absence in military or
   government service, shall constitute termination of employment shall be
   determined by the Board at the time. For purposes of this Plan, transfer of
   employment between the Company and its subsidiaries shall not be deemed
   termination of employment.

        10.8  Other Employee Benefits

        The value of an Award granted to a Participant who is an employee, and
   the amount of any compensation deemed to be received by an employee as a
   result of any exercise or purchase of Common Stock pursuant to an Award or
   sale of shares received under the Plan, will not constitute "earnings" or
   "compensation" with respect to which any other employee benefits of such
   employee are determined, including without limitation benefits under any
   pension, stock ownership, stock purchase, life insurance, medical, health,
   disability or salary continuation plan.

        10.9  Legal Holidays

        If any day on or before which action under the Plan must be taken
   falls on a Saturday, Sunday or legal holiday, such action may be taken on
   the next succeeding day not a Saturday, Sunday or legal holiday.

        10.10  Foreign Nationals

        Without amending the Plan, Awards may be granted to persons who are
   foreign nationals or employed outside the United States or both, on such
   terms and conditions different from those specified in the Plan, as may, in
   the judgment of the Board, be necessary or desirable to further the purpose
   of the Plan.

   11.  Termination and Amendment
 
        The Plan shall remain in full force and effect until terminated by the
   Board. Subject to the last sentence of this Section 11, the Board may at
   any time or times amend the Plan or any outstanding Award for any purpose
   that may at the time be permitted by law, or may at any time terminate the
   Plan as to any further grants of Awards. No amendment, unless approved by
   the Stockholders, shall be effective if it would cause the Plan to fail to
   satisfy the requirements of the federal tax law or regulation relating to
   incentive stock options or the requirements of Rule 16b-3 (or any successor
   rule) of the Exchange Act. No amendment of the Plan or any agreement
   evidencing Awards under the Plan may adversely affect the rights of any
   participant under any Award previously granted without such participant's
   consent.

   Thermo Process Systems Inc.
   Notes to Consolidated Financial Statements


   1.  Summary of Significant Accounting Policies

   Relationship with Thermo Electron Corporation
   Thermo Process Systems Inc. (the Company) was incorporated on May 30, 1986,
   as an indirect, wholly owned subsidiary of Thermo Electron Corporation
   (Thermo Electron). As of April 1, 1995, Thermo Electron owned 13,933,591
   shares of the Company's common stock, representing 80% of such stock
   outstanding.

   Principles of Consolidation
   The accompanying financial statements include the accounts of the Company
   and its majority- and wholly owned subsidiaries. All material intercompany
   accounts and transactions have been eliminated. Majority-owned subsidiaries
   include Thermo Remediation Inc. (Thermo Remediation), a publicly held
   subsidiary; J. Amerika N.V. (J. Amerika), a privately held subsidiary; and
   Thermo Terra Tech, a 51%-owned joint venture that was formed in May 1994
   with Thermo Instrument Systems Inc. (Thermo Instrument), another public
   subsidiary of Thermo Electron (Notes 3 and 14). Majority-owned subsidiaries
   that were included in the Company's Thermo Remediation subsidiary effective
   October 1, 1993 were TPST Soil Recyclers of South Carolina Inc. (TPST South
   Carolina), TPST Soil Recyclers of Virginia Inc. (TPST Virginia), TPST Soil
   Recyclers of Southern California Inc. (TPST Southern California), and TPST
   Soil Recyclers of Florida Inc. (TPST Florida).

   Fiscal Year
   The Company has adopted a fiscal year ending the Saturday nearest March 31.
   References to fiscal 1995, 1994, and 1993 are for the fiscal years ended
   April 1, 1995, April 2, 1994, and April 3, 1993, respectively. Fiscal years
   1995 and 1994 each included 52 weeks; 1993 included 53 weeks.

   Revenue Recognition
   For the majority of its operations, the Company recognizes revenues upon
   completion of services it renders. Revenues from soil-remediation services
   are recognized as soil is processed. With respect to soil-remediation
   services, the Company bills customers upon receipt of the contaminated soil
   at its remediation centers. Amounts billed in excess of revenues recognized
   are classified as "Billings in excess of revenues earned" in the
   accompanying balance sheet.
        Revenues and profits on substantially all contracts are recognized
   using the percentage-of-completion method. Revenues recorded under the
   percentage-of-completion method were $47,446,000 in fiscal 1995,
   $46,072,000 in fiscal 1994, and $48,578,000 in fiscal 1993. The percentage
   of completion is determined by relating either the actual costs or actual
   labor incurred to date to management's estimate of total costs or total
   labor, respectively, to be incurred on each contract. If a loss is
   indicated on any contract in process, a provision is made currently for the
   entire loss. The Company's contracts generally provide for billing of
   customers upon the attainment of certain milestones specified in each
   contract. Revenues earned on contracts in process in excess of billings are
   classified as "Unbilled contract costs and fees" in the accompanying
   balance sheet. There are no significant amounts included in the
   accompanying balance sheet that are not expected to be recovered from
   existing contracts at current contract values, or that are not expected to
   be collected within one year, including amounts billed but not paid under
   retainage provisions.

   Notes to Consolidated Financial Statements


   1.  Summary of Significant Accounting Policies (continued)

   Gain on Issuance of Stock by Subsidiaries
   At the time a subsidiary sells its stock to unrelated parties at a price in
   excess of its book value, the Company's net investment in that subsidiary
   increases. If at that time the subsidiary is an operating entity and not
   engaged principally in research and development, the Company records the
   increase as a gain. See Note 11 for a description of gains recorded.
        If gains have been recognized on issuances of a subsidiary's stock and
   shares of the subsidiary are subsequently repurchased either by the
   subsidiary, the Company, or Thermo Electron, gain recognition does not
   occur on issuances subsequent to the date of a repurchase until such time
   as shares have been issued in an amount equivalent to the number of
   repurchased shares.

   Income Taxes
   The Company adopted Statement of Financial Accounting Standards (SFAS) No.
   109, "Accounting for Income Taxes," as of the beginning of fiscal 1994.
   Under SFAS No. 109, deferred income taxes are recognized based on the
   expected future tax consequences of differences between the financial
   statement basis and the tax basis of assets and liabilities calculated
   using enacted tax rates in effect for the year in which the differences are
   expected to be reflected in the tax return. Prior to fiscal 1994, the
   Company recorded income taxes on timing differences between financial
   statement and tax treatment of income and expenses under Accounting
   Principles Board Opinion No. 11. Upon adoption of SFAS No. 109, the Company
   recorded a cumulative benefit of $500,000, which is included in the
   accompanying statement of income.

   Earnings per Share
   Earnings per share have been computed based on the weighted average number
   of shares outstanding during the year. Because the effect of the exercise
   of common stock equivalents was immaterial, they have been excluded from
   the earnings per share calculation. Fully diluted earnings per share have
   not been presented because the effect of the conversion of the Company's
   subordinated convertible debentures would be antidilutive.

   Cash and Cash Equivalents
   As of April 1, 1995, $30,802,000 of the Company's cash equivalents were
   invested in a repurchase agreement with Thermo Electron. Under this
   agreement, the Company in effect lends excess cash to Thermo Electron,
   which Thermo Electron collateralizes with investments principally
   consisting of corporate notes, U.S. government agency securities, money
   market funds, commercial paper, and other marketable securities, in the
   amount of at least 103% of such obligation. The Company's funds subject to
   the repurchase agreement are readily convertible into cash by the Company
   and have an original maturity of three months or less. The repurchase
   agreement earns a rate based on the Commercial Paper Composite Rate plus 25
   basis points, set at the beginning of each quarter. As of April 1, 1995,
   the Company's cash equivalents were also invested in a money market fund.
   Cash equivalents are carried at cost, which approximates market value.

   1.  Summary of Significant Accounting Policies (continued)

   Available-for-sale and Held-to-maturity Investments
   Pursuant to SFAS No. 115, "Accounting for Certain Investments in Debt and
   Equity Securities," debt and marketable equity securities that the Company
   considers available-for-sale are accounted for at market value. Debt
   securities that the Company intends to hold to maturity are accounted for
   at amortized cost. See Note 2 for a description of these investments.

   Inventories
   Inventories are stated at the lower of cost (on an average-cost basis) or
   market value and include materials and labor. The components of inventories
   are as follows:

   Property, Plant and Equipment
   The costs of additions and improvements are capitalized, while maintenance
   and repairs are charged to expense as incurred. The Company provides for
   depreciation and amortization using the straight-line method over the
   estimated useful lives of the property as follows: buildings and

   Other Assets
   "Other assets" in the accompanying balance sheet includes the cost of
   acquired technology and other specifically identifiable intangible assets
   that are being amortized using the straight-line method over their
   estimated useful lives, which range from 5 to 12 years. These assets were
   $9,994,000 and $4,212,000, net of accumulated amortization of $3,217,000
   and $2,037,000, at fiscal year-end 1995 and 1994, respectively.

   1.  Summary of Significant Accounting Policies (continued)

   Cost in Excess of Net Assets of Acquired Companies
   The excess of cost over the fair value of net assets of acquired businesses
   is amortized using the straight-line method over 40 years. Accumulated
   amortization was $4,721,000 and $3,744,000 at fiscal year-end 1995 and
   1994, respectively. The Company assesses the future useful life of this
   asset whenever events or changes in circumstances indicate the current
   useful life has diminished. The Company considers the future undiscounted
   cash flows of the acquired businesses in assessing the recoverability of
   this asset.

   Foreign Currency
   All assets and liabilities of the Company's foreign subsidiaries are
   translated at year-end exchange rates, and revenues and expenses are
   translated at average exchange rates for the year in accordance with SFAS
   No. 52, "Foreign Currency Translation." Resulting translation adjustments
   are reflected as a separate component of shareholders' investment titled
   "Cumulative translation adjustment." Foreign currency transaction gains and
   losses are included in the accompanying statement of income and are not
   material for the three years presented.


   2.  Available-for-sale and Held-to-maturity Investments

   Effective April 2, 1994, the Company adopted SFAS No. 115, "Accounting for
   Certain Investments in Debt and Equity Securities." In accordance with SFAS
   No. 115, the Company's debt and marketable equity securities that are
   classified as "Available-for-sale investments" in the accompanying balance
   sheet are carried at market value, with the difference between cost and
   market value, net of related tax effects, recorded currently as a component
   of shareholders' investment titled "Net unrealized gain (loss) on
   available-for-sale investments." "Effect of change in accounting principle"
   in the accompanying statement of shareholders' investment represents the
   unrealized gain, net of related tax effects, pertaining to short-term
   available-for-sale investments held by the Company on April 2, 1994. 
        In order to meet the Company's obligation to the former owner of Elson
   T. Killam Associates, Inc., which the Company acquired in February 1995,
   the Company purchased securities with a maturity date equal to the date the
   Company's zero coupon promissory note is due (see Note 3). These securities
   are classified as "Held-to-maturity investments" in the accompanying
   balance sheet and are carried at amortized cost.

        Short- and long-term available-for-sale investments in the
   accompanying fiscal 1995 balance sheet include $6,679,000 with contractual
   maturities of one year or less and $9,040,000 with contractual maturities
   of more than one year through five years. Actual maturities may differ from
   contractual maturities as a result of the Company's intent to sell these
   securities prior to maturity and as a result of put and call options that
   enable the Company and/or the issuer to redeem these securities at an
   earlier date.
        The cost of available-for-sale investments that were sold was based on
   specific identification in determining realized gains recorded in the
   accompanying statement of income. Gain on sale of investments in fiscal
   1995 and 1994 resulted from gross realized gains relating to the sale of
   available-for-sale investments.
        "Long-term held-to-maturity investments" in the accompanying fiscal
   1995 balance sheet represent investments in U.S. treasury bonds that mature
   in February and May 1998. It is the Company's intent and ability to hold
   these securities to maturity.


   3.  Joint Venture and Acquisitions

   Joint Venture
   In May 1994, the Company entered into an agreement establishing Thermo
   Terra Tech, an environmental services joint venture, with Thermo Instrument
   that became effective April 4, 1994. The Company contributed to the joint
   venture Terra Tech Labs, Inc. (later renamed Thermo Analytical Inc.) and 
                                       13PAGE
<PAGE>

   Thermo Process Systems Inc.
   Notes to Consolidated Financial Statements


   3.  Joint Venture and Acquisitions (continued)

   approximately $31 million in cash and short-term investments, $15 million
   of which was borrowed from Thermo Electron pursuant to a promissory note
   (Note 8). Thermo Instrument contributed its environmental services
   businesses (Environmental Services Businesses of Thermo Instrument or
   Environmental Services Businesses) that consist of a national network of
   analytical laboratories, and businesses that provide nuclear-radiation
   safety and environmental science and consulting services. As of April 1,
   1995, the Company owned 51% of Thermo Terra Tech. Accordingly, the joint
   venture's operating results are consolidated with the Company's operating
   results. Under the terms of the joint venture agreement, 66.67% of income
   earned by the joint venture from April 4, 1994 to April 1, 1995 was
   allocated to Thermo Instrument.
        Because the Company and the Environmental Services Businesses were
   deemed for accounting purposes to be under control of their common majority
   owner, Thermo Electron, the transaction was accounted for at historical
   cost in a manner similar to a pooling of interests. Accordingly, in fiscal
   1994 all historical financial information presented was restated to include
   the accounts and operations of the Environmental Services Businesses. In
   fiscal 1994 and 1993, amounts earned by the Environmental Services
   Businesses of Thermo Instrument were allocated to Thermo Instrument through
   minority interest expense in the accompanying financial statements.
        In May 1995, the Company agreed to dissolve the Thermo Terra Tech
   joint venture and to purchase the businesses formerly operated by the joint
   venture (Note 14).

   Acquisitions
   On March 29, 1995, the Company's J. Amerika subsidiary acquired all of the
   outstanding capital stock of Refining and Trading Holland B.V., which
   conducts business under the name North Refinery, from Stalt Holding B.V.
   North Refinery, located in Delfzijl, Holland. North Refinery specializes in
   processing "off-spec" and contaminated petroleum fluids into usable
   products such as gas oil, diesel oil, and fuel oil. The purchase price for
   North Refinery's stock was 9,568,000 Dutch guilders (approximately
   $6,180,000) and 228,570 shares of J. Amerika's capital stock, valued at
   1,327,000 Dutch guilders (approximately $857,000). J. Amerika has also
   agreed to pay, after the fifth anniversary date of the closing, an amount
   equal to 20% of the amount by which the cumulative pretax profits of North
   Refinery's business over the five-year period ending on such anniversary
   exceeds 5,000,000 Dutch guilders.
        In February 1995, the Company acquired all of the outstanding capital
   stock of Engineering, Technology and Knowledge Corporation (ETKC) from Nord
   Est S.A., a French industrial company (Nord Est). ETKC's sole subsidiary,
   Elson T. Killam Associates, Inc. (Killam Associates), is a leading provider
   of comprehensive environmental consulting and professional engineering
   services in selected areas of the U.S. The purchase price for ETKC's stock
   was $12,566,000 in cash and a zero coupon promissory note with a face value
   of $28,000,000 and a present value of $22,300,000 as of the acquisition
   closing date, payable in February and May 1998. The purchase price is
   subject to a post-closing adjustment based on Killam Associates' net
   tangible book value as of January 29, 1995. The Company has also agreed to
   pay, after the third anniversary date of the closing, an amount equal to
   30% of the amount by which Killam Associates' cumulative net income for the
   three-year period ending on such anniversary exceeds $13 million. In a

   3.  Joint Venture and Acquisitions (continued)

   related transaction, certain members of Killam Associates' senior
   management (the Killam Management) exchanged outstanding options to
   purchase shares of Killam Associates' capital stock for options to purchase
   an aggregate of 847,678 shares of the Company's common stock, which options
   were valued at $6,923,000. Additional options to purchase shares of Killam
   Associates' capital stock were canceled in exchange for cash payments to
   the Killam Management in the aggregate amount of $1,922,000. The Company
   borrowed the cash portion of the purchase price, including cash used to
   purchase U.S. treasury bonds to collateralize the promissory note delivered
   to Nord Est, from Thermo Electron through the issuance of a $38 million
   promissory note (Note 8).
        In October 1994, the Company's Thermo Remediation subsidiary acquired
   a soil-remediation facility in South Tacoma, Washington (renamed TPST
   Woodworth) from Woodworth & Company, Inc. The purchase price for TPST
   Woodworth was $4,701,000 in cash. In connection with the financing of
   acquisitions, Thermo Remediation issued to Thermo Electron a $4,000,000
   promissory note (Note 8). During fiscal 1995, the Company's Thermo
   Remediation subsidiary and Thermo Terra Tech joint venture made other
   acquisitions for an aggregate of $14.2 million in cash.
        In January 1994, the Company acquired Terra Tech Labs, Inc. (Terra
   Tech), a privately held company specializing in fast-response testing of
   petroleum-contaminated soils and groundwater in the southwestern U.S. The
   acquisition was made for $1,500,000 in cash and up to an additional
   $1,200,000 payable over a two-year period if the business achieves certain
   performance goals. Terra Tech has facilities in Santa Ana, California, and
   Phoenix, Arizona, as well as four mobile units, which provide services
   primarily to the petroleum industry and consulting engineers.
        In November 1993, the Company acquired a fluids recovery company based
   in Mesa, Arizona (renamed Thermo Fluids) for $2,650,000 in cash and
   immediately transferred it to Thermo Remediation in exchange for a
   $2,650,000 principal amount 3.875% subordinated convertible note due 2000.
   In addition, due to Thermo Fluids having met certain performance criteria,
   on February 1, 1995, the Company issued to the former owner of Thermo
   Fluids 178,060 restricted shares of its common stock valued at $840,000.
   Thermo Remediation in turn issued to the Company 127,369 restricted shares
   of its common stock valued at $840,000. In August 1994, Thermo Remediation
   loaned $700,000, included in "Other assets" in the accompanying fiscal 1995
   balance sheet, to the former owner of Thermo Fluids in connection with the
   termination of employment with Thermo Fluids and the settlement of the
   parties' respective obligations to one another. This obligation is
   represented by a promissory note bearing interest at a rate equal to the
   rate of interest on one-year U.S. treasury notes, adjusted on an annual
   basis, and is secured by a pledge of the Company's common stock issued to
   the former owner. The note is receivable in three equal installments
   commencing in March 1997.
        These acquisitions have been accounted for using the purchase method
   of accounting, and their results of operations have been included in the
   accompanying financial statements from their respective dates of
   acquisition. The aggregate cost of these acquisitions exceeded the
   estimated fair value of the acquired net assets by $36,838,000, which is

   being amortized over 40 years. Allocation of the purchase price for these
   acquisitions was based on estimates of the fair value of the net assets
   acquired and, for acquisitions completed in fiscal 1995, is subject to
   adjustment.
        Based on unaudited data, the following table presents selected
   financial information for the Company, North Refinery, Killam Associates,
   and TPST Woodworth on a pro forma basis, assuming the companies had been

   financial statements of the acquisitions not included in the pro forma data
   was not significant.

   includes $1,848,000 for estimated severance, relocation, and other reserves
   associated with acquisitions.


   4.  Stock-based Compensation Plans

   The Company has stock-based compensation plans for its key employees,
   directors, and others. Two of these plans, adopted in 1986, permit the
   grant of nonqualified and incentive stock options. A third plan, adopted in
   fiscal 1994, permits the grant of a variety of stock and stock-based awards
   as determined by the human resources committee of the Company's Board of
   Directors (the Board Committee), including restricted stock, stock options,
   stock bonus shares, or performance-based shares. To date, only nonqualified
   stock options have been awarded under these plans. The option recipients
   and the terms of options granted under these plans are determined by the
   Board Committee. Generally, options granted to date are exercisable
   immediately, but are subject to certain transfer restrictions and the right
   of the Company to repurchase shares issued upon exercise of the options at
   the exercise price, upon certain events. The restrictions and repurchase
   rights generally lapse ratably over periods ranging from three to ten years
   after the first anniversary of the grant date, depending on the term of the
   option, which may range from five to twelve years. Nonqualified stock
   options may be granted at any price determined by the Board Committee,
   although incentive stock options must be granted at not less than fair
   market value of the Company's stock on the date of grant. Generally, all
   options have been granted at fair market value. The Company also has a
   directors' stock option plan, adopted in September 1991, that provides for
   the grant of stock options to nonemployee directors pursuant to a formula
   approved by the Company's shareholders. Options awarded under this plan are
   exercisable six months after the date of grant and expire three to seven
   years after the date of grant. In addition to the Company's stock-based
   compensation plans, certain officers and key employees may also participate
                                       16PAGE

   5.  Employee Benefit Plans

   Employee Stock Purchase Plan
   The majority of the Company's full-time U.S. employees are eligible to
   participate in an employee stock purchase plan sponsored by the Company.
   Under this plan, shares of the Company's and Thermo Electron's common stock
   may be purchased at the end of a 12-month plan year at 85% of the fair
   market value at the beginning of the plan year, and the shares purchased
   are subject to a one-year resale restriction. Shares are purchased through
   payroll deductions of up to 10% of each participating employee's gross
   wages. During fiscal 1995, 1994, and 1993, the Company issued 21,999
   shares, 28,845 shares, and 23,677 shares of its common stock, respectively,
   under this plan. Employees of the Environmental Services Businesses of
   Thermo Instrument participated in an employee stock purchase plan sponsored
   by Thermo Instrument through the end of November 1994. Thereafter, they
   became eligible to participate in the Company's employee stock purchase
   plan.

   5.  Employee Benefit Plans (continued)

   401(k) Savings Plan and Employee Stock Ownership Plan
   The majority of the Company's full-time U.S. employees are eligible to
   participate in Thermo Electron's 401(k) savings plan and employee stock
   ownership plan. Contributions to the Thermo Electron 401(k) savings plan
   are made by both the employee and the Company. Company contributions are
   based upon the level of employee contributions. Certain subsidiaries of the
   Company also have a defined contribution retirement plan, a
   union-sponsored, collectively bargained multiemployer pension plan, and
   401(k) savings plans. For these plans, the Company contributed and charged
   to expense $1,654,000, $1,465,000, and $1,449,000 in fiscal 1995, 1994, and
   1993, respectively.

   Postemployment Benefits
   The Company provides certain postemployment benefits to former or inactive
   employees. In accordance with SFAS No. 112, "Employers' Accounting for
   Postemployment Benefits," the Company recognizes the cost of postemployment
   benefits if certain criteria are met and the amount of benefits can be
   reasonably estimated.


   6.  Income Taxes

   As discussed in Note 1, the Company adopted SFAS No. 109 in fiscal 1994.

        The components of the income tax (provision) benefit are as follows:

   realization of the tax benefits attributable to federal operating losses,

   acquisitions. The valuation allowance will be used to reduce "Cost in
   excess of net assets of acquired companies" when any portion of the related
   deferred tax asset is recognized.

   6.  Income Taxes (continued)

        A provision has not been made for U.S. or additional foreign taxes on
   $2,200,000 of undistributed earnings of foreign subsidiaries that could be
   subject to taxation if remitted to the U.S. because the Company plans to
   keep these amounts permanently reinvested overseas. The Company believes
   that any additional U.S. tax liability due upon remittance of such earnings
   would be immaterial due to available U.S. foreign tax credits.


   7.  Commitments and Contingencies

   Operating Leases
   The Company leases, land, office and manufacturing facilities, and
   equipment under operating leases expiring at various dates through fiscal
   2009. The accompanying statement of income includes expenses from operating
   leases of $2,491,000, $2,509,000, and $2,468,000 in fiscal 1995, 1994, and
   1993, respectively. Future minimum payments due under noncancelable
   operating leases at April 1, 1995, are $2,594,000 in fiscal 1996;
   $1,659,000 in fiscal 1997; $1,120,000 in fiscal 1998; $765,000 in fiscal
   1999; $403,000 in fiscal 2000; and $1,632,000 in fiscal 2001 and
   thereafter. Total future minimum lease payments are $8,173,000. See Note 9
   for office and manufacturing facilities leased from Thermo Electron.
        In March 1991, the Company's TPST Virginia subsidiary entered into a
   seven-year agreement, terminable at the Company's option with 90 days'
   notice, to operate one or more of its soil-remediation units at a site
   owned by a third party. Under the terms of the agreement, the Company pays
   a fee based on the gross remediation revenues generated from the operations
   at the site, less certain operating costs incurred by the Company. The
   accompanying statement of income includes expenses relating to this
   agreement of $307,000, $410,000, and $625,000 in fiscal 1995, 1994, and
   1993, respectively.
        In December 1994, the Company's Thermo Remediation subsidiary acquired
   a soil-remediation facility in Baltimore County, Maryland from the
   principals of Bryn Awel Corporation (Bryn Awel). Thermo Remediation will
   pay to Bryn Awel a royalty equal to 7.5% of the revenues in excess of $2.0
   million each year from soil remediated at this facility. Thermo Remediation
   has an option to terminate such royalty payments (i) at anytime after the
   fifth anniversary of the acquisition in exchange for a payment equal to a
   multiple of the appraised value of the royalty stream or (ii) at anytime
   after the tenth anniversary of the acquisition in exchange for a payment
   equal to a multiple of the average of the annual royalty payments over the
   prior ten years.

   Litigation
   In January 1995, the Company, Thermo Remediation, and several third parties
   filed a lawsuit against Recycling Sciences International, Inc. (RSI)
   requesting a declaratory judgment that six U.S. patents owned by RSI are
   invalid and not infringed by Thermo Remediation's soil-remediation services
   and equipment, and asking the court to enjoin RSI from asserting any of
   these patents against the Company or Thermo Remediation. The suit follows
   continued allegations by RSI that Thermo Remediation's activities in
   treating petroleum-contaminated soil infringe a number of these patents.
   The Company agreed, in connection with the formation of Thermo Remediation,
   to indemnify and hold Thermo Remediation harmless against damages or other
   costs associated with any claims of infringement of intellectual property
   by the technology transferred by the Company to Thermo Remediation,

   7.  Commitments and Contingencies (continued)

   including claims which may be made by RSI. The Company continues to believe
   that RSI's accusations are unfounded and that Thermo Remediation's
   activities do not infringe any valid claims of the patents.
        The Company is also contingently liable with respect to lawsuits and
   other matters that arose in the ordinary course of business. In the opinion
   of management, these contingencies will not have a material effect upon the
   financial position of the Company or its results of operations.


   8.  Long-term Obligations and Other Financing Arrangements

   Long-term obligations of the Company are as follows:

                                                             1995      1994

   these debentures were converted into common stock of the Company.
        The annual requirements for long-term obligations as of April 1, 1995,
   are $652,000 in fiscal 1996; $15,610,000 in fiscal 1997; $68,441,000 in
   fiscal 1998; $11,395,000 in fiscal 1999; $110,000 in fiscal 2000; and
   $1,295,000 thereafter. Total requirements of long-term obligations are
   $97,503,000.
        The Company's J. Amerika subsidiary has a line of credit, denominated
   in Netherlands guilders, under which approximately $3,200,000 may be
   borrowed at the Netherlands discount rate plus 125 basis points. No funds
   were borrowed under this arrangement during fiscal 1995.

   8.  Long-term Obligations and Other Financing Arrangements (continued)

        In December 1994, Thermo Remediation borrowed $4,000,000 from Thermo
   Electron through issuance of a promissory note due June 29, 1995, and
   bearing interest at the Commercial Paper Composite Rate plus 25 basis
   points. The average interest rate on the note was 6.5% in fiscal 1995. The
   promissory note is included in "Notes payable and current maturities of
   long-term obligations" in the accompanying fiscal 1995 balance sheet (Note
   14).


   9.  Related Party Transactions

   Corporate Services Agreement
   The Company and Thermo Electron have a corporate services agreement under
   which Thermo Electron's corporate staff provides certain administrative
   services, including certain legal advice and services, risk management,
   certain employee benefit administration, tax advice and preparation of tax
   returns, centralized cash management, and certain financial and other
   services, for which the Company pays Thermo Electron annually an amount
   equal to 1.20% of the Company's revenues. Prior to January 1, 1995, the
   Company paid an annual fee equal to 1.25% of the Company's revenues. Prior
   to January 3, 1993, the Company paid an annual fee equal to 1% of the
   Company's revenues. The annual fee is reviewed and adjusted annually by
   mutual agreement of the parties. For these services, the Company was
   charged $1,653,000, $1,377,000, and $1,119,000 in fiscal 1995, 1994, and
   1993, respectively. The corporate services agreement is renewed annually
   but can be terminated upon 30 days' prior notice by the Company or upon the
   Company's withdrawal from the Thermo Electron Corporate Charter (the Thermo
   Electron Corporate Charter defines the relationship among Thermo Electron
   and its majority-owned subsidiaries). Management believes that the service
   fee charged by Thermo Electron is reasonable and that such fees are
   representative of the expenses the Company would have incurred on a
   stand-alone basis. For additional items such as employee benefit plans,
   insurance coverage, and other identifiable costs, Thermo Electron charges
   the Company based upon costs attributable to the Company.

   Development Agreement
   The Company and Thermo Electron entered into a development agreement under
   which Thermo Electron agreed to fund up to $4.0 million of the direct and
   indirect costs of the Company's development of soil-remediation centers. In
   exchange for this funding, the Company granted Thermo Electron a royalty
   equal to approximately 3% of net revenues from soil-remediation services
   performed at the centers developed under the agreement. The royalty
   payments may cease if the amounts paid by the Company yield a certain
   internal rate of return to Thermo Electron on the funds advanced to the
   Company under the agreement. The Company recorded contract revenues of
   $776,000 and $1,793,000 under this agreement for development costs expended
   in fiscal 1994 and 1993, respectively. As of October 2, 1993, funding under
   this agreement was completed. Two sites have been developed under this
   agreement. The Company paid royalties of $432,000 in fiscal 1995, $351,000
   in fiscal 1994, and $149,000 in fiscal 1993 relating to this agreement,
   which are included in "Selling, general and administrative expenses" in the
   accompanying statement of income.

   Operating Leases
   The Company leases or subleases two office and manufacturing facilities
   from Thermo Electron under lease agreements expiring in fiscal 1997 and
   2005. The accompanying statement of income includes expenses from the
   operating lease and sublease of $537,000 in fiscal 1995 and $426,000 in
   both fiscal 1994 and 1993. The future minimum payments due under the lease

   14.  Subsequent Events

   Acquisitions
   On May 9, 1995, the Company agreed to dissolve the Thermo Terra Tech joint
   venture and to purchase the businesses formerly operated by the joint
   venture from Thermo Instrument for $34,267,000 in cash, effective April 2,
   1995. As a result of this transaction, the Company increased its ownership
   in the businesses operated by the joint venture from 51% to 100%. Based on
   unaudited data, if the acquisition of Thermo Instrument's share of such
   businesses by the Company had occurred at the beginning of fiscal 1994,
   income before cumulative effect of change in accounting principle and
   earnings per share on a pro forma basis would have been $5,953,000 and
   $.35, respectively, for fiscal 1995 and $6,209,000 and $.37, respectively,
   for fiscal 1994. The Company borrowed the purchase price from Thermo
   Electron through the issuance of a $35 million promissory note that bears
   interest at the Commercial Paper Composite Rate plus 25 basis points and is
   due May 13, 1997.

   14.  Subsequent Events (continued)

        On May 10, 1995, the Company acquired substantially all of the assets
   of Lancaster Laboratories, Inc. and its affiliate Clewmark Holdings
   (collectively Lancaster Laboratories). Lancaster Laboratories, based in
   Lancaster, Pennsylvania, is a provider of high-quality analytical services
   to the environmental, food, and pharmaceutical industries. Lancaster
   Laboratories had gross revenues of approximately $29,000,000 for the fiscal
   year ended September 30, 1994. The base purchase price for the assets was
   $16,760,000 in cash, plus the assumption of approximately $5,400,000 in
   bank indebtedness existing as of the closing of the acquisition. The
   purchase price is subject to a post-closing adjustment. The Company has
   also agreed to pay an amount, not to exceed $600,000, if Lancaster
   Laboratories achieves certain performance goals through the period ending
   September 30, 1995. In no event will the aggregate purchase price,
   including bank indebtedness assumed by the Company, exceed $25,000,000.

   Debenture Offering and Private Placement of Subsidiary Common Stock
   On May 4, 1995, the Company's Thermo Remediation subsidiary issued and sold
   in Europe $37,950,000 principal amount of 4 7/8% subordinated convertible
   debentures due 2000.  The debentures are convertible into shares of Thermo
   Remediation's common stock at a conversion price of $17.92 per share and
   are guaranteed on a subordinated basis by Thermo Electron.  Thermo Process
   has agreed to reimburse Thermo Electron in the event Thermo Electron is
   required to make a payment under the guarantee.  In addition, Thermo
   Remediation sold 500,000 shares of its common stock at $13.25 per share in
   a private placement for net proceeds of approximately $6,600,000. Following
   the private placement, the Company owned 63% of the outstanding stock of
   Thermo Remediation. In June 1995, Thermo Remediation repaid its $4,000,000
   note payable to Thermo Electron with proceeds from the offering.

   Management's Discussion and Analysis of Financial Condition and Results of
   Operations

   Overview

   The Company's majority-owned public subsidiary, Thermo Remediation Inc.
   (Thermo Remediation), provides soil-remediation services through a network
   of regional centers. These soil-remediation centers thermally treat soil to
   remove and destroy petroleum contamination caused by leaking storage tanks,
   spills, and other sources. Through Thermo Remediation's November 1993
   acquisition of Thermo Fluids, the Company also collects and recycles used
   motor oil and provides services such as wastewater processing. In February
   1995, the Company acquired Elson T. Killam Associates, Inc. (Killam
   Associates), a leading provider of comprehensive environmental consulting
   and professional engineering services in selected areas of the United
   States. The Company's majority-owned J. Amerika N.V. (J. Amerika)
   subsidiary is a provider in the Netherlands of underground tank and other
   environmental services. In March 1995, J. Amerika acquired Refining and
   Trading Holland B.V. (North Refinery), which specializes in processing
   "off-spec" and contaminated petroleum fluids into usable products. In
   recognition of its changing focus, J. Amerika intends to change its name to
   Thermo EuroTech N.V. The Company's Thermo Terra Tech businesses provide
   environmental science and consulting services, laboratory-based testing,
   and nuclear-radiation safety services.  Terra Tech Labs, Inc. (later
   renamed Thermo Analytical Inc.), which was acquired in January 1994,
   specializes in fast-response testing of petroleum-contaminated soils and
   groundwater. In August 1994, Thermo Terra Tech acquired RMC Environmental
   Services, Inc. (RMC), an environmental consulting and analytical laboratory
   services firm specializing in environmental science, hydropower consulting,
   and analytical laboratory services. The Company also performs metallurgical
   processing services, using thermal-treatment equipment owned by the Company
   and designs, manufactures, and installs advanced custom-engineered
   thermal-processing systems.

   Results of Operations

   Fiscal 1995 Compared With Fiscal 1994

   Total revenues were $133.8 million in fiscal 1995, compared with $110.1
   million in fiscal 1994, an increase of 21%. Service revenues increased 27%
   to $119.4 million in fiscal 1995 from $94.3 million in fiscal 1994.
   Revenues from analytical and consulting services increased 29% to $70.9
   million in fiscal 1995 from $54.8 million in fiscal 1994. This increase is
   due to the inclusion of approximately $13.2 million in revenues from
   businesses acquired in late fiscal 1994 and in fiscal 1995 and, to a lesser
   extent, revenues generated from a long-term environmental restoration
   contract for the U.S. Department of Energy's Hanford site. Revenues from
   the Company's remediation services increased 27% to $36.5 million in fiscal
   1995, due primarily to an increase in the volume of soil processed at the
   Company's soil-remediation centers located in Southern California and
   Florida and, to a lesser extent, additional revenues of $3.8 million from
   businesses acquired in late fiscal 1994 and in fiscal 1995. Metallurgical
   processing services revenues increased 15% to $12.3 million in fiscal 1995
   from $10.7 million in fiscal 1994, due primarily to the Company's efforts
   to increase its nongovernment business.

   Operations (continued)

   Fiscal 1995 Compared With Fiscal 1994 (continued)

        "Contract revenues from related party" in fiscal 1994 and 1993
   represents funding under an agreement between the Company and Thermo
   Electron Corporation (Thermo Electron) to fund up to $4.0 million of the
   direct and indirect costs of the Company's development of soil-remediation
   centers (see Note 9 to Consolidated Financial Statements). The Company
   earned no profit from this funding. As of October 2, 1993, funding under
   this agreement was completed. Any expenses incurred in connection with the
   development of additional soil-remediation centers subsequent to October 2,
   1993, are included in "Product and new business development expenses" in
   the accompanying statement of income. 

        Product revenues from sales of custom-engineered thermal-processing
   systems were $14.4 million in fiscal 1995, compared with $15.0 million in
   fiscal 1994. Although this business remains depressed and is subject to
   intense competition, backlog increased to $4.4 million at April 1, 1995,
   compared with $3.5 million at April 2, 1994.

        The gross profit margin increased to 26% in fiscal 1995 from 24% in
   fiscal 1994. The gross profit margin on service revenues increased to 28%
   in fiscal 1995 from 26% in fiscal 1994. The gross profit margin on
   analytical and consulting services improved to 25% in fiscal 1995 from 23%
   in fiscal 1994 due to higher gross margins at businesses acquired during
   the year. The gross profit margin on remediation services remained
   relatively constant at 37% in fiscal 1995, compared with 36% in fiscal
   1994. The gross profit margin on metallurgical processing services
   increased to 14% in fiscal 1995 from 8% in fiscal 1994 as a result of the
   Company's efforts to increase nongovernment business. The gross profit
   margin on product revenues increased to 17% in fiscal 1995 from 13% in
   fiscal 1994 as a result of more profitable contracts in process during
   fiscal 1995, compared with fiscal 1994.

        Selling, general and administrative expenses as a percentage of
   revenues remained relatively unchanged at 19.6% in fiscal 1995, compared
   with 19.2% in fiscal 1994.

        The Company recorded gains on the issuance of stock by subsidiaries of
   $1.3 million in fiscal 1995 and $4.5 million in fiscal 1994. See Notes 1
   and 11 to Consolidated Financial Statements for a more complete description
   of these transactions.

        Net interest income was $0.5 million in fiscal 1995, compared with
   $0.6 million in fiscal 1994. An increase in interest expense due to
   borrowings from Thermo Electron in May 1994 to fund the Company's
   investment in Thermo Terra Tech and in February 1995 to fund the Company's
   acquisition of Killam Associates was offset in part by higher average
   investment balances.

        See Note 6 to Consolidated Financial Statements for a reconciliation
   of the statutory tax rate to the effective tax rate.

   Management's Discussion and Analysis of Financial Condition and Results of
   Operations (continued)

   Fiscal 1994 Compared With Fiscal 1993

   Total revenues were $110.1 million in fiscal 1994, compared with $104.9
   million in fiscal 1993, an increase of 5%. Service revenues increased 9% to
   $94.3 million in fiscal 1994 from $86.3 million in fiscal 1993. Remediation
   services contributed approximately $9.7 million of additional revenues,
   while revenues from analytical and consulting services were virtually
   unchanged from the prior year. The increase in revenues from remediation
   services is primarily attributable to the first full year of operations at
   three new soil-remediation centers and, to a lesser extent, the November
   1993 acquisition of Thermo Fluids. The increase in service revenues is also
   due to the January 1994 acquisition of Terra Tech Labs, Inc., which
   contributed revenues of $0.8 million. Metallurgical processing services
   revenues declined approximately $1.4 million as a result of continued
   slowdowns in the aerospace and defense industries.

        "Contract revenues from related party" in fiscal 1994 and fiscal 1993
   represents funding under an agreement between the Company and Thermo
   Electron to fund up to $4.0 million of the direct and indirect costs of the
   Company's development of soil-remediation centers (see Note 9 to
   Consolidated Financial Statements).

        Product revenues from sales of custom-engineering thermal-processing
   systems were $15.0 million in fiscal 1994, compared with $16.9 million in
   fiscal 1993. This business remains depressed. As a result of the continued
   worldwide overcapacity in the automotive and heavy-equipment industries,
   recent increases in automobile sales have not generated corresponding
   increases in capital spending on products such as those offered by the
   Company's Holcroft division. In addition, the Company has encountered
   significant competition in this business. As a result of these market
   conditions, backlog declined to $3.5 million at April 2, 1994, from $6.7
   million at April 3, 1993.

        The gross profit margin increased to 24% in fiscal 1994 from 20% in
   fiscal 1993. The gross profit margin on service revenues increased to 26%
   in fiscal 1994 from 22% in fiscal 1993 due to higher gross profit margins
   from remediation services and analytical and consulting services. The gross
   profit margin on remediation services improved due primarily to an increase
   in the volume of soil processed and operational efficiencies achieved
   through the introduction of more automated and efficient remediation
   equipment during fiscal 1994. Improvements from analytical and consulting
   services relate to ongoing cost-containment programs. These increases were
   offset in part by lower gross profit margins at the metallurgical
   processing services operations as a result of a decline in revenues. The
   gross profit margin on product revenues increased slightly to 13% in fiscal
   1994 from 12% in fiscal 1993. Despite reduced volume at the Company's
   Holcroft division, actions to reduce costs have allowed the Company to
   improve its gross profit margin.

        Selling, general and administrative expenses increased to $21.2
   million in fiscal 1994 from $17.0 million in fiscal 1993 due to the
   operation of six soil-remediation centers for the full year in fiscal 1994,
   compared with four centers for the majority of fiscal 1993; the inclusion
   of $506,000 of Thermo Fluids' and Terra Tech Labs, Inc.'s selling, general
   and administrative expenses; as well as expanded efforts for a national
   marketing program and marketing efforts at planned remediation site
   locations.

   Operations (continued)

   Fiscal 1994 Compared With Fiscal 1993 (continued)

        "Costs associated with divisional restructuring" in fiscal 1994
   represents a one-time noncash charge for the write-off of mobile
   soil-remediation assets and other related expenses. The Company has decided
   to no longer actively pursue mobile soil-remediation projects.

        The Company recorded gains on the issuance of stock by subsidiaries of
   $4.5 million in fiscal 1994 and $2.3 million in fiscal 1993. See Notes 1
   and 11 to Consolidated Financial Statements for a more complete description
   of these transactions.

        Net interest income decreased to $0.6 million in fiscal 1994 from $0.8
   million in fiscal 1993, primarily as a result of lower prevailing interest
   rates.

        The Company recorded a tax benefit of $40,000 in fiscal 1994, compared
   with a tax provision of $1.0 million in fiscal 1993. See Note 6 to
   Consolidated Financial Statements for a reconciliation of the statutory tax
   rate to the effective tax rate.

        During the first quarter of fiscal 1994, the Company adopted Statement
   of Financial Accounting Standards No. 109, "Accounting for Income Taxes,"
   which resulted in a cumulative tax benefit of $0.5 million.

   Financial Condition

   Liquidity and Capital Resources

        Consolidated working capital, including cash, cash equivalents, and
   short-term available-for-sale investments, increased to $64.7 million at
   April 1, 1995 from $51.6 million at April 2, 1994. Cash, cash equivalents,
   and short- and long-term available-for-sale investments were $51.5 million
   at April 1, 1995, compared with $50.5 million at April 2, 1994. In
   addition, at April 1, 1995, the Company had $22.6 million of long-term
   held-to-maturity investments. Of the $51.5 million balance at April 1,
   1995, $16.9 million was held by the Company's majority-owned subsidiaries,
   $31.0 million was held by the Thermo Terra Tech joint venture, and the
   remainder by the Company and its wholly owned subsidiaries. In May 1994,
   the Company borrowed $15 million from Thermo Electron to fund the Company's
   investment in Thermo Terra Tech. In February 1995, the Company borrowed $38
   million from Thermo Electron to fund the Company's acquisition of Killam
   Associates. In connection with the financing of acquisitions, Thermo
   Remediation issued to Thermo Electron a $4 million promissory note. During
   fiscal 1995, the Company expended $38.2 million, net of cash, for
   acquisitions. In September 1994 and October 1994, the Company's J. Amerika
   subsidiary completed private placements of its common stock for net
   proceeds of $2.4 million. In May 1994, the Company's Thermo Remediation
   subsidiary completed a private placement of its common stock for net
   proceeds of $0.7 million.

   Management's Discussion and Analysis of Financial Condition and Results of
   Operations (continued)

   Liquidity and Capital Resources (continued)

        Subsequent to the end of fiscal 1995, the Company agreed to dissolve
   the Thermo Terra Tech joint venture and to purchase from Thermo Instrument
   the businesses formerly operated by the joint venture for $34.3 million in
   cash. To fund the purchase, the Company borrowed $35 million from Thermo
   Electron through the issuance of a promissory note due May 1997. Also
   subsequent to the end of fiscal 1995, the Company acquired Lancaster
   Laboratories, Inc. and its affiliate Clewmark Holdings for approximately
   $16.8 million in cash, plus the assumption of approximately $5.4 million in
   bank indebtedness. The purchase price is subject to a post-closing
   adjustment, yet in no event will the aggregate purchase price exceed $25
   million.

        Also subsequent to the end of fiscal 1995, the Company's Thermo
   Remediation subsidiary issued and sold in Europe $38 million principal
   amount of 4 7/8% subordinated debentures due 2000 and convertible into
   shares of Thermo Remediation common stock. In addition, Thermo Remediation
   sold 500,000 shares of its common stock in a private placement for net
   proceeds of approximately $6.6 million. In June 1995, Thermo Remediation
   repaid its $4 million note payable to Thermo Electron with proceeds from
   the offering.

        Although the Company has no material capital expenditure commitments,
   such expenditures will largely be affected by the number of soil-
   remediation centers that can be developed or acquired during the year, as
   well as acquisitions of companies that are consistent with the Company's
   strategic plan for growth. The Company believes that it has adequate
   resources to meet the financial needs of its current operations for the
   foreseeable future.
