                                     PART I

    Item 1. Business

    (a) General Development of Business

        Thermo Electron Corporation and its subsidiaries (the Company or the
    Registrant) develop, manufacture, and market analytical and monitoring
    instruments; biomedical products including heart-assist devices,
    respiratory-care equipment, and mammography systems; paper recycling and
    papermaking equipment; alternative-energy systems; industrial process
    equipment; and other specialized products. The Company also provides a
    range of services that include industrial outsourcing, particularly in
    environmental-liability management, laboratory analysis, and
    metallurgical processing; and conducts advanced-technology research and
    development. The Company performs its business through divisions and
    wholly owned subsidiaries, as well as majority-owned subsidiaries that
    are partially owned by the public or by private investors.

        A key element in the Company's growth has been its ability to
    commercialize innovative products and services emanating from research
    and development activities conducted by the Company's various
    subsidiaries. The Company's strategy has been to identify business
    opportunities arising from social, economic, and regulatory issues, and
    to seek a leading market share through the application of proprietary
    technology. As part of this strategy, the Company continues to focus on
    the acquisition of complementary businesses that can be integrated into
    its existing core businesses to leverage access to new markets.

        The Company believes that maintaining an entrepreneurial atmosphere
    is essential to its continued growth and development. To preserve this
    atmosphere, the Company has adopted a strategy of spinning out certain of
    its businesses into separate subsidiaries and having these subsidiaries
    sell a minority interest to outside investors. The Company believes that
    this strategy provides additional motivation and incentives for the
    management of the subsidiaries through the establishment of subsidiary-
    level stock option incentive programs, as well as capital to support the
    subsidiaries' growth. The Company's wholly and majority-owned
    subsidiaries are provided with centralized corporate development,
    administrative, financial, and other services that would not be available
    to many independent companies of similar size. As of March 11, 1998, the
    Company had 28 subsidiaries that have sold minority equity interests, 22
    of which are publicly traded and 6 of which are privately held.

        The Company is a Delaware corporation and was incorporated in 1956.
    The Company completed its initial public offering in 1967 and was listed
    on the New York Stock Exchange in 1980.

    Forward-looking Statements

        Forward-looking statements, within the meaning of Section 21E of the
    Securities Exchange Act of 1934, are made throughout this Annual Report
    on Form 10-K. For this purpose, any statements contained herein that are
    not statements of historical fact may be deemed to be forward-looking
    statements. Without limiting the foregoing, the words "believes,"

                                        2PAGE
<PAGE>
    "anticipates," "plans," "expects," "seeks," "estimates," and similar
    expressions are intended to identify forward-looking statements. There
    are a number of important factors that could cause the results of the
    Company to differ materially from those indicated by such forward-looking
    statements, including those detailed under the heading "Forward-looking
    Statements" in the Registrant's 1997 Annual Report to Shareholders, which
    statements are incorporated herein by reference.

    (b) Financial Information About Industry Segments

        The Company's products and services are divided into six segments:
    Instruments, Alternative-energy Systems, Paper Recycling, Biomedical
    Products, Industrial Outsourcing, and Advanced Technologies. Products or
    services within a particular segment are provided by more than one
    subsidiary, and certain subsidiaries' products or services are included
    in more than one segment. The principal products and services offered by
    the Company in the six industry segments are described below. Financial
    information concerning the Company's industry segments is summarized in
    Note 14 to Consolidated Financial Statements in the Registrant's 1997*
    Annual Report to Shareholders, which information is incorporated herein
    by reference.

    (c) Description of Business

        (i) Principal Products and Services

    Instruments

        The Company, through its Thermo Instrument Systems Inc. subsidiary,
    is a worldwide leader in the development, manufacture, and marketing of
    instruments used to identify complex chemical compounds, toxic metals,
    and other elements in a broad range of liquids, solids, and gases, as
    well as to analyze air pollution and radioactivity. Thermo Instrument
    also provides instruments that control, monitor, image, inspect, and
    measure various industrial processes and life sciences phenomena.

        Thermo Instrument historically has expanded both through the
    acquisition of companies and product lines and through the internal
    development of new products and technologies. During the past several
    years, Thermo Instrument has completed a number of complementary
    acquisitions that have provided additional technologies, specialized
    manufacturing or product-development expertise, and broader capabilities
    in marketing and distribution.

        For example, in March 1997, Thermo Instrument acquired 95% of Life
    Sciences International PLC, a London Stock Exchange-listed company.
    Subsequently, Thermo Instrument acquired the remaining shares of Life
    Sciences' capital stock. Life Sciences manufactures laboratory science
    equipment, appliances, instruments, consumables, and reagents for the
    research, clinical, and industrial markets.

    * References to 1997, 1996, and 1995 herein are for the fiscal years
      ended January 3, 1998, December 28, 1996, and December 30, 1995,
      respectively.

                                        3PAGE
<PAGE>
        In March 1996, Thermo Instrument completed the acquisition of a
    substantial portion of the businesses constituting the Scientific
    Instruments Division of Fisons plc, a wholly owned subsidiary of
    Rhone-Poulenc Rorer Inc. These businesses substantially added to Thermo
    Instrument's research, development, manufacture, and sale of analytical
    instruments to industrial and research laboratories worldwide. Certain of
    the Fisons businesses were since sold by Thermo Instrument to a number of
    its public subsidiaries that have complementary technologies and markets.

        Thermo Instrument adopted the Company's spinout strategy in an effort
    to more clearly focus its many instrumentation technologies on specific
    niche markets. To date, Thermo Instrument has completed initial public
    offerings of ThermoSpectra Corporation, ThermoQuest Corporation, Thermo
    Optek Corporation, Thermo BioAnalysis Corporation, Metrika Systems
    Corporation, and Thermo Vision Corporation. Thermo Instrument has
    completed a private placement of common stock of its ONIX Systems Inc.
    subsidiary and has filed a registration statement with the Securities and
    Exchange Commission for a public offering of ONIX Systems common stock.
    Thermo Instrument's subsidiaries are outlined below:

        ThermoSpectra develops, manufactures, and markets precision imaging
    and inspection, temperature-control, and test and measurement
    instruments. These instruments are generally combined with proprietary
    operations and analysis software to provide industrial and research
    customers with integrated systems that address their specific needs.

        ThermoQuest is a leading provider of mass spectrometers, liquid
    chromatographs, and gas chromatographs for the pharmaceutical,
    environmental, and industrial marketplaces. These analytical instruments
    are used in the quantitative and qualitative chemical analysis of organic
    and inorganic compounds at ultratrace levels of detection. ThermoQuest
    also supplies scientific equipment for the preparation and preservation
    of chemical samples, and consumables for the chromatography industry.

        Thermo Optek is a worldwide leader in the development, manufacture,
    and marketing of analytical instruments that use a range of light- and
    energy-based techniques. Thermo Optek's instruments are used in the
    quantitative and qualitative chemical analysis of elements and molecular
    compounds in a variety of solids, liquids, and gases.

        Thermo BioAnalysis develops, manufactures, and markets instruments,
    consumables, and information-management systems used in biochemical
    research and production, as well as in clinical diagnostics. Thermo
    BioAnalysis focuses on three principal product areas: life sciences
    instrumentation and consumables, information-management systems, and
    health physics instrumentation.

        Metrika Systems manufactures process optimization systems that
    provide on-line, real-time analysis of the elemental composition of bulk
    raw materials in basic-materials production processes, including coal,
    cement, and minerals. In addition, Metrika Systems manufactures
    industrial gauging and process-control instruments and systems used
    principally by manufacturers of finished web materials, such as sheet

                                        4PAGE
<PAGE>
    metal, rubber, and plastic foils, to measure and control parameters such
    as thickness and coating weight of such materials.

        Thermo Vision, which became a public subsidiary of Thermo Instrument
    in December 1997, designs, manufactures, and markets a diverse array of
    photonics (light-based) products, including optical components, imaging
    sensors and systems, lasers, optically based instruments, opto-
    electronics, and fiber optics. These products are used in applications
    including medical diagnostics, semiconductor production, X-ray imaging,
    physics research, and telecommunications.

        ONIX Systems, a privately held subsidiary of Thermo Instrument,
    designs, develops, markets, and services sophisticated field measurement
    instruments and on-line sensors for process-control industries,
    particularly oil and gas. Systems provide real-time data collection,
    analysis, and local control functions regarding the flow, level, density,
    or composition of a particular material.

        Thermo Instrument also has wholly owned businesses, including the
    Life Sciences Clinical Instrument Division, which provides an array of
    clinical laboratory equipment and consumables, and Thermo Monitoring
    Instruments, which produces instruments and complete systems for
    detecting and monitoring environmental pollutants from industrial and
    mobile sources, and for detecting radioactive contamination.

    Alternative-energy Systems

        The Company's Alternative-energy Systems segment includes the
    operation of independent (non-utility) power plants that operate using
    environmentally sound fuels and technologies, the development of
    engineered clean fuels, and the manufacture and sale of biopesticides.
    This segment also includes the manufacture, sale, and servicing of
    intelligent traffic-control systems, industrial refrigeration equipment;
    natural gas engines; packaged cooling and cogeneration systems; and steam
    turbines and compressors.

        Through its Thermo Ecotek Corporation subsidiary, the Company
    designs, develops, owns, and operates independent (non-utility) electric
    power-generation facilities that use environmentally responsible fuels,
    including agricultural and wood wastes, referred to as "biomass." Thermo
    Ecotek currently operates seven biomass facilities. Its facilities are
    developed and operated through joint ventures or limited partnerships in
    which it has a majority interest, or through wholly owned subsidiaries.

        Thermo Ecotek intends to pursue development of biomass and other
    power-generation projects both in the U.S. and overseas. In 1996, Thermo
    Ecotek formed a joint venture in Italy to develop, own, and operate
    biomass-fueled electric power facilities, and in January 1997, announced
    a joint agreement to expand two district energy centers in the Czech
    Republic. In the U.S., where the Company believes that utility
    deregulation may present opportunities for updating aging plants, Thermo
    Ecotek signed a $9.5 million agreement in November 1997 to purchase two
    deregulated plants in southern California for possible refurbishing and
    repowering.
                                        5PAGE
<PAGE>
        Thermo Ecotek is expanding beyond power generation into other
    products and processes that protect the environment. In August 1995,
    Thermo Ecotek, through two wholly owned subsidiaries, entered into a
    Limited Partnership Agreement with KFx Wyoming, Inc., a subsidiary of KFx
    Inc., to develop, construct, and operate a coal-beneficiation plant in
    Gillette, Wyoming. The facility employs patented "clean coal" technology
    to remove excess moisture and increase energy from subbituminous coal
    extracted from Wyoming's Powder River Basin.

        In May 1996, Thermo Ecotek entered the biopesticide business by
    acquiring the assets, subject to certain liabilities, of the biopesticide
    division of W.R. Grace & Co. (renamed Thermo Trilogy), which develops,
    manufactures, and markets environmentally friendly products for
    agricultural pest control. In January 1997, Thermo Trilogy acquired the
    assets of biosys, inc., a producer of pheromone, neem/azadiractin,
    nematodes, and virus-based biopesticide products, as well as
    disease-resistant sugar cane, and in November 1997, purchased the Bt
    biopesticide product line of Novartis AG.

        The Company, through its Thermo Power Corporation subsidiary,
    manufactures, markets, and services intelligent traffic-control systems,
    industrial refrigeration equipment, engines for vehicular and stationary
    applications, natural gas-fueled commercial cooling and cogeneration
    systems, and, through its privately held ThermoLyte Corporation
    subsidiary, is developing a line of gas-powered lighting products for
    commercialization.

        In November 1997, Thermo Power completed a cash tender offer for Peek
    plc, based in the U.K. Through Peek, the Company offers a range of
    intelligent traffic-control systems for urban traffic control, motorway
    management, and public transportation management in cities worldwide.
    Systems include traffic-signal synchronization systems to minimize
    congestion, variable message systems to advise drivers of accidents or
    construction, video systems to provide real-time analysis of traffic
    flows at intersections and on highways, as well as automatic
    toll-collection systems. Peek also has developed high-resolution video
    equipment to aid police officers in monitoring traffic violations.

        Through its industrial refrigeration business, Thermo Power supplies
    standard and custom-designed industrial refrigeration systems used
    primarily by the food-processing, petrochemical, and pharmaceutical
    industries. Thermo Power is also a supplier of both remanufactured and
    new commercial cooling equipment for sale or rental. The commercial
    cooling equipment is used primarily in institutions and commercial
    buildings, as well as by service contractors.

        Thermo Power also develops, manufactures, markets, and services
    gasoline engines for recreational boats, propane and gasoline engines for
    lift trucks, and natural gas engines for vehicles and stationary
    industrial applications; and designs, develops, markets, and services
    packaged cooling and cogeneration systems fueled principally by natural
    gas.

                                        6PAGE

        The Company's Alternative-energy Systems segment also includes a
    U.K.-based manufacturer of steam turbines and compressors.

    Paper Recycling

        The Company designs, manufactures, and sells paper recycling and
    papermaking equipment and accessory products, and electroplating and
    aqueous cleaning systems.

        Through its Thermo Fibertek Inc. subsidiary, the Company is a leading
    designer and manufacturer of processing machinery, accessories, and
    water-management systems for the paper and paper recycling industries.
    Thermo Fibertek's custom-engineered systems remove debris, impurities,
    and ink from wastepaper, and process it into a fiber mix used to produce
    recycled paper. Thermo Fibertek's principal products include
    custom-engineered systems and equipment for the preparation of wastepaper
    for conversion into recycled paper, accessory equipment and related
    consumables important to the efficient operation of papermaking machines,
    and water-management systems essential for draining, purifying, and
    recycling process water.

        In May 1997, Thermo Fibertek acquired the majority of the assets,
    subject to certain liabilities, of the stock-preparation business of
    Black Clawson Company and certain of its affiliates. In August 1997, the
    Company acquired the remaining assets of the stock-preparation business
    of Black Clawson Company and such affiliates. This business, renamed
    Thermo Black Clawson, is a leading supplier of recycling equipment used
    in processing fiber for the manufacture of "brown paper," such as that
    used for corrugated boxes.

        In September 1996, Thermo Fibergen Inc. became a majority-owned,
    public subsidiary of Thermo Fibertek. Thermo Fibergen is developing and
    commercializing equipment and systems to recover materials from
    papermaking sludge generated by plants that produce virgin and recycled
    pulp and paper. Thermo Fibergen's GranTek Inc. subsidiary uses a patented
    process to convert papermaking sludge into granules that are used for
    applications including carriers for agricultural chemicals, oil and
    grease absorption, and catbox filler.

        Through a wholly owned subsidiary, the Company also manufactures
    electroplating systems and related waste-treatment equipment and
    accessories, as well as aqueous systems for cleaning metal parts without
    using ozone-damaging solvents.

    Biomedical Products

    imaging, cardiovascular support, respiratory care, neurodiagnostics,
    sleep analysis, wireless patient monitoring, and blood management. The
    Company's biomedical products are provided to hospitals, clinics,
    universities, private-practice medical offices, and medical research
    facilities.

                                        7PAGE
<PAGE>
        Its wholly owned Thermo Biomedical group includes Bear Medical
    Systems, the business of which was acquired from Allied Healthcare
    Products, Inc. in October 1997. Bear Medical designs, manufactures, and
    markets respiratory products, primarily ventilators.

        Also part of the Company's Thermo Biomedical group are SensorMedics
    Corporation, a leading provider of systems for pulmonary function
    diagnosis and a producer of respiratory gas analyzers, physiological
    testing equipment, and automated sleep-analysis systems; and Medical Data
    Electronics, a manufacturer of patient-monitoring systems. Both companies
    were acquired in 1996.

        Nicolet Biomedical Inc., another wholly owned subsidiary of the
    Company, is a leading manufacturer of biomedical instruments for
    assessing muscle, nerve, sleep, hearing, and brain blood-flow disorders,
    various neurologic disorders, and for related work in clinical
    neurophysiology. In September 1997, Nicolet acquired IMEX Medical
    Systems, Inc., a leading manufacturer of products used to evaluate
    peripheral vascular disease, as well as products to detect fetal
    heartbeat. This subsidiary is now called Nicolet Vascular Inc.

        Another wholly owned subsidiary, Bird Medical Technologies, Inc.,
    develops, manufactures, and sells respiratory-care equipment and
    accessories and infection-control products to hospitals, subacute-care
    facilities, outpatient surgical centers, doctors, dentists, the military,
    and to other manufacturers.

        Thermo Cardiosystems Inc., a public subsidiary of Thermedics Inc.,
    has developed an implantable left ventricular-assist system (LVAS) called
    HeartMate(TM) that, when implanted alongside the natural heart, is
    designed to take over the pumping function of the left ventricle for
    patients whose hearts are too damaged or diseased to produce adequate
    blood flow. Thermo Cardiosystems has two versions of the LVAS: a
    pneumatic (or air-driven) system that can be controlled by either a
    bedside console or portable unit, and an electric system that features an
    internal electric motor powered by an external battery-pack worn by the
    patient.

        The air-driven HeartMate system has received both the European
    Conformity Mark and U.S. Food and Drug Administration (FDA) approval for
    commercial sale. The electric version of the LVAS, which also holds the
    CE Mark, is currently awaiting commercial approval by the FDA for use as
    a bridge to transplant. In Europe, the device is used both as a bridge to
    transplant and as an alternative to medical therapy.

        In December 1996, Thermo Cardiosystems acquired the business of
    Nimbus Medical, Inc., a research and development organization involved
    for more than 20 years in technology for ventricular-assist devices and
    total artificial hearts, including high-speed rotary blood pumps, which
    are relatively small and could potentially provide cardiac support in
    small adults and children.

        Also part of Thermo Cardiosystems is International Technidyne
    Corporation, a leading manufacturer of hemostasis-management products,

                                        8PAGE
<PAGE>
    including blood coagulation-monitoring instruments, and a supplier of
    skin-incision devices used to draw small blood samples precisely and with
    minimal discomfort.

        Trex Medical Corporation, a public subsidiary of ThermoTrex
    Corporation, designs, manufactures, and markets a range of medical
    imaging systems. It is the world's leading manufacturer of mammography
    equipment and minimally invasive digital breast-biopsy systems. Trex
    Medical also provides general-purpose and specialty radiographic systems,
    such as those used in the diagnosis and treatment of coronary artery
    disease and other vascular conditions.

        In early December, Trex Medical submitted a 510(k) application to the
    FDA seeking clearance to market its digital imaging system for
    mammography. The Company believes that an advantage of digital imaging is
    that radiologists can manipulate and enhance image quality to scrutinize
    subtle differences that may otherwise go undetected on film-based X-rays.
    If the FDA approves the digital imaging system for mammography
    applications, Trex Medical plans to develop its digital technology for
    use in certain of its other products.

        ThermoLase Corporation, also a public subsidiary of ThermoTrex,
    operates a network of spas that offer its patented SoftLight(R)
    hair-removal system, for which it received FDA clearance in April 1995.
    The SoftLight system uses a low-energy dermatology laser in combination
    with a lotion to remove hair. ThermoLase submitted a 510(k) application
    for its laser-based skin-retexturing system, based on data from clinical
    trials.

        ThermoLase currently has 14 Spa Thira locations in the U.S., with 3
    spas outside the U.S.: in Paris, France; Lugano, Switzerland; and Dubai,
    U.A.E. To complement its Spa Thira salons, ThermoLase has commenced a
    program to license the SoftLight hair-removal process to physicians for
    use in their practices. ThermoLase has established a number of joint
    ventures and other physician-licensing arrangements to market its
    SoftLight processes internationally.

        ThermoLase also manufactures and markets personal care products sold
    through department stores, salons, and spas, including the lotion that is
    used in the SoftLight hair-removal process.

        Trex Communications Corporation, a majority-owned, privately held
    subsidiary of ThermoTrex, is developing laser communications technology
    designed to transmit very large amounts of data quickly, and also designs
    and markets interactive information and voice-response systems, as well
    as automated calling equipment.

    Industrial Outsourcing

        Through its Thermo TerraTech Inc. subsidiary, the Company provides
    outsourcing services, primarily in environmental-liability management and
    infrastructure planning and design, with specialization in the areas of
    municipal and industrial water quality management, bridge and highway

    presence and amount of relevant chemicals. Thermedics also manufactures
    on-line process monitors used by power plants and semiconductor
    manufacturers to detect contaminants in high-purity water.

        (ii) New Products

        The Company's business includes the development and introduction of
    new products and may include entry into new business segments. The
    Company has made no commitments to new products that require the
    investment of a material amount of the Company's assets, nor does it have
    any definitive plans to enter new business segments that would require
    such an investment (see Section (xi) "Research and Development").

        (iii) Raw Materials

        Certain raw materials used in the manufacture of Thermo
    Cardiosystem's LVAS are available from only one or two suppliers. Thermo
    Cardiosystems is making efforts to minimize the risks associated with
    sole sources and ensure long-term availability, including qualifying
    alternative materials or developing alternative sources for materials and
    components supplied by a single source. Although the Company believes
    that it has adequate supplies of materials and components to meet demand
    for the LVAS for the foreseeable future, no assurance can be given that
    the Company will not experience shortages of certain materials or
    components in the future that could cause delays in Thermo Cardiosystems'
    LVAS development program or adversely affect Thermo Cardiosystems'
    ability to manufacture and ship LVAS units to meet demand.

        Except as described above, in the opinion of management, the Company
    has a readily available supply of raw materials for all of its
    significant products from various sources and does not anticipate any
    difficulties in obtaining the raw materials essential to its business.

        (iv) Patents, Licenses, and Trademarks

        The Company considers patents to be important in the present
    operation of its business; however, the Company does not consider any
    patent, or related group of patents, to be of such importance that its
    expiration or termination would materially affect the Company's business
    taken as a whole. The Company seeks patent protection for inventions and
    developments made by its personnel and incorporated into its products or
    otherwise falling within its fields of interest. Patent rights resulting
    from work sponsored by outside parties do not always accrue exclusively
    to the Company and may be limited by agreements or contracts.

        The Company protects some of its technology as trade secrets and,
    where appropriate, uses trademarks or registers its products. It also
    enters into license agreements with others to grant and/or receive rights
    to patents and know-how.

                                       12PAGE
<PAGE>
        (v) Seasonal Influences

        Thermo Ecotek earns a disproportionately high share of its income
    from May through October due to the rate structures under the power sales
    agreements relating to its California power plants, which provide strong
    incentives to operate during this period of high demand. Conversely,
    Thermo Ecotek historically has operated at a loss or at a marginal profit
    during the first quarter due to the rate structure under these
    agreements.

        Funding patterns of government entities, as well as seasonality, are
    expected to result in fluctuations in quarterly revenues and income at
    Thermo Power's Peek subsidiary. Peek has historically experienced
    relatively higher sales and net income in the second and fourth calendar
    quarters and relatively lower sales and net income in the first and third
    calendar quarters.

        While Thermo TerraTech conducts significant operations year-round,
    the majority of its businesses experience seasonal fluctuations due to
    adverse weather during winter months.

        There are no other material seasonal influences on the Company's
    sales of products and services.

        (vi) Working Capital Requirements

        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

        No single customer accounted for more than 10% of the Company's total
    revenues in any of the past three years. The Advanced Technologies
    segment derived approximately 34%, 38%, and 52% of its revenues in 1997,
    1996, and 1995, respectively, from contracts with various agencies of the
    U.S. government. In connection with the development of power plants,
    Thermo Ecotek typically enters into long-term power supply contracts with
    a single customer for the sale of power generated by each plant. The
    Alternative-energy Systems segment derived 15%, 16%, and 16% of its
    revenues in 1997, 1996, and 1995, respectively, from Pacific Gas &
    Electric and 15%, 16%, and 15% of its revenues in 1997, 1996, and 1995,
    respectively, from Southern California Edison.

                                                        ========     ========

        Backlog includes the uncompleted portion of research and development
    contracts and the uncompleted portion of certain contracts that are
    accounted for using the percentage-of-completion method. Certain of such
    firm orders are cancellable by the customer upon the payment of a
    cancellation charge. The Company believes substantially all of the
    year-end 1997 backlog will be filled during 1998.

        (ix) Government Contracts

        Approximately 5% of the Company's total revenues in 1997 were derived
    from contracts or subcontracts with the federal government, which 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

        The Company is engaged in many highly competitive industries. The
    nature of the competition in each of the Company's segments is described
    below:

    Instruments

        The Company is among the principal manufacturers of analytical
    instrumentation. Within the markets for the Company's analytical
    instrument products, the Company competes with several large corporations
    that have broad product offerings, such as Hewlett-Packard Company;
    Perkin-Elmer Corp.; Varian Associates, Inc.; and Hitachi, Ltd., as well
    as numerous smaller companies that address particular segments of the
    industry or specific geographic areas. The Company's instruments business
    generally competes on the basis of technical advances that result in new
    products and improved price/performance ratios, reputation among
    customers as a quality leader for products and services, and active
    research and application-development programs. To a lesser extent, the
    Company competes on the basis of price.

                                       14PAGE
<PAGE>
    Alternative-energy Systems

        The worldwide independent power market consists of numerous
    companies, ranging from small startups to multinational industrial
    companies. In addition, a number of regulated utilities have created
    subsidiaries that compete as non-utility generators. Non-utility
    generators often specialize in market "niches," such as a specific
    technology or fuel (i.e., gas-fired cogeneration, refuse-to-energy,
    hydropower, geothermal, wind, solar, wood, or coal) or a specific region
    of the country where they believe they have a market advantage. However,
    many non-utility generators, including the Company, seek to develop
    projects on a best-available-fuel basis. The Company competes primarily
    on the basis of project experience, technical expertise, capital
    resources, and power pricing.

        The market in which the Company's biopesticide business competes is
    highly competitive and subject to rapid technological change. Many
    competitors are large chemical and pharmaceutical companies with greater
    financial, marketing, and technological resources than the Company. The
    Company's biopesticide business competes primarily based on effective-
    ness, and also on price, ease of use, and environmental impact of use.

        The market for traffic products and services is extremely
    competitive, and the Company expects that competition will continue to
    increase, with the principal factors being price, functionality,
    reliability, service and support, and vendor and product reputation,
    along with industry and general economic trends. The Company believes
    that it is a leading manufacturer and supplier of traffic products, and
    considers its major competitor to be Siemens AG. However, the traffic
    market is highly fragmented and competition varies significantly
    depending on the individual product. 

        The Company's sale of industrial refrigeration systems is subject to
    intense competition. The industrial refrigeration market is mature,
    highly fragmented, and extremely dependent on close customer contacts.
    Major industrial refrigeration companies, of which the Company is one,
    account for approximately one-half of worldwide sales, with the balance
    generated by many smaller companies. The Company competes principally on
    the basis of its advanced control systems and overall quality,
    reliability, service, and price. The Company believes it is a leader in
    remanufactured refrigeration equipment. The Company competes in this
    market primarily based on price, delivery time, and customized equipment.

    Paper Recycling

        The Company faces significant competition in the markets for paper
    recycling and water-handling equipment and papermaking accessories, and
    competes in these markets primarily on the basis of quality, service,
    technical expertise, and product innovation. The Company is a leading
    supplier of de-inking systems for paper recycling and accessory equipment
    for papermaking machines, and competes in these markets primarily on the
    basis of service, technical expertise, and performance.

                                       15PAGE
<PAGE>
    Biomedical Products

        Competition in the markets for most of the Company's biomedical
    products, including those manufactured by Thermo Cardiosystems,
    ThermoTrex, Nicolet Biomedical, Bird Medical Technologies, SensorMedics,
    Medical Data Electronics, Bear Medical Systems, and Nicolet Vascular, is
    based to a large extent upon technical performance.

        The Company is aware of one other company that has submitted a PMA
    application with the FDA for an implantable LVAS that would compete with
    Thermo Cardiosystems' LVAS. The Company is unaware whether this PMA
    application has been accepted for filing by the FDA. Also, the Company is
    aware of one other company that has received approval by the FDA Advisory
    Panel on Circulatory System Devices and subsequent commercial approval
    for its cardiac-assist device. This is an external device that is
    positioned on the outside of the patient's chest and is intended for
    short-term use in the hospital environment. The Company is also aware
    that a total artificial heart is currently undergoing clinical trials.
    The requirement of obtaining FDA approval for commercial sale of an LVAS
    is a significant barrier to entry into the U.S. market for these devices.
    There can be no assurance, however, that FDA regulations will not change
    in the future, reducing the time and testing required for others to
    obtain FDA approval. In addition, other research groups and companies are
    developing cardiac-assist systems using alternative technologies or
    concepts, one or more of which might prove functionally equivalent to, or
    more suitable than, the Company's systems. Among products that have been
    approved for commercial sale, the Company competes primarily on the basis
    of performance, service capability, reimbursement status, and price.

        The Company is one of a number of competitors in the markets for
    mammography and general radiographic systems and is one of two
    competitors in the market for stereotactic breast-biopsy systems. The
    Company competes in these markets primarily on the basis of product
    features, product performance, and reputation, as well as price and
    service. The markets in which the Company competes with these products
    are characterized by rapid technological change. The Company believes
    that in order to be competitive in these markets it will be important to
    continue to be technologically innovative.

        The Company's SoftLight laser hair-removal system competes with other
    laser-based systems, electrolysis, and other traditional hair-removal
    methods, such as shaving and waxing. In 1997, five other laser
    manufacturers received clearance from the FDA to market their laser-based
    systems for the removal of unwanted facial and body hair. The laser-based
    hair-removal market is characterized by rapid technological change, and
    the Company believes that it must continue to be technologically
    innovative in order to compete in this market. In addition, the SoftLight
    system competes with electrolysis providers, many of whom are small
    practitioners with well-established networks of client relationships. The
    Company believes that competition for its hair-removal services is based
    primarily on efficacy, price, comfort, and safety.

                                       16PAGE
<PAGE>
    Industrial Outsourcing

        The Company seeks to compete in the market for soil-remediation
    services based on its ability to offer customers superior protection from
    environmental liabilities. However, with relaxed regulatory standards in
    many states, the Company faces intense competition in local markets from
    landfills, other treatment technologies, and from companies competing
    with similar technologies, limiting the volume of soil to be treated and
    the prices that can be charged by the Company. Pricing is therefore a
    major competitive factor for the Company.

        The Company's metallurgical services business competes in specialty
    machining services. Competition is based principally on services
    provided, turnaround time, and price.

        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.

    Advanced Technologies

        In its contract research and development business, the Company not
    only competes with other companies and institutions that perform similar
    services, but must also rely on the ability of government agencies and
    other clients to obtain allocations of research and development monies to
    fund contracts with the Company. The Company competes for research and
    development programs principally on the basis of technical innovations.
    As government funding becomes more scarce, particularly for defense
    projects, the competition for such funding will become more intense. In
    addition, as the Company's programs move from the development stage to
    commercialization, competition is expected to intensify.

        Thermo Sentron competes with several international and regional
    companies in the market for its products. Thermo Sentron's competitors in
    the packaged goods market differ from those in the bulk materials market.
    The principal competitive factors in both markets are customer service
    and support, quality, reliability, and price.

        Thermedics Detection's product quality-assurance systems compete with
    chemical-detection systems manufactured by several companies and with
    other technologies and processes for product quality assurance.
    Competition in the markets for all of the Company's detection products is
    based primarily on performance, service, and price. There are a number of
    competitors in the market for instruments that detect explosives,
    including makers of other chemical-detection instruments as well as
    enhanced X-ray detectors.

                                       17PAGE
<PAGE>
        Thermo Voltek is a leading supplier of electromagnetic compatibility
    testing equipment. The Company competes in this market primarily on the
    basis of performance, technical expertise, reputation, and price. In the
    market for power amplifiers, Thermo Voltek competes with several
    companies worldwide primarily on the basis of technical expertise,
    reputation, and price.

        Thermedics' electrode-based chemical-measurement products compete
    with several international companies. In the markets for these products,
    Thermedics competes on the basis of performance, service, technology, and
    price.

        (xi) Research and Development

        During 1997, 1996, and 1995, the Company expended $335,372,000,
    $299,271,000, and $269,329,000, respectively, on research and
    development. Of these amounts, $143,743,000, $144,823,000, and
    $167,120,000, respectively, were sponsored by customers and $191,629,000,
    $154,448,000, and $102,209,000, respectively, were Company-sponsored.

        (xii) Environmental Protection Regulations

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

        (xiii) Number of Employees

        At January 3, 1998, the Company employed approximately 22,400
    persons.

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

        Financial information about exports by domestic operations and about
    foreign operations is summarized in Note 14 to Consolidated Financial
    Statements in the Registrant's 1997 Annual Report to Shareholders, which

    To the Shareholders and Board of Directors of
    Thermo Electron Corporation:

        We have audited in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Thermo
    Electron Corporation's Annual Report to Shareholders incorporated by
    reference in this Form 10-K, and have issued our report thereon dated
    February 18, 1998. 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 23 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 financial data
    required to be set forth therein in relation to the basic consolidated
    financial statements taken as a whole.

        Waltham M.A. 02254

                                                               July 1995

        Dear Sirs

        We are pleased to advise you that Barclays Bank PLC (the  "Bank")
        has agreed to provide in aggregate short term facilities of up to
        US$100,000,000 (one hundred million United States ("US") Dollars)
        or its currency  equivalent (referred  to as  the "Facility")  to
        Thermo  Electron   Corporation   (the   "Parent")   and   certain
        Subsidiaries as may be nominated from time to time in  accordance
        with clause 3 (such companies being individually referred to as a
        "Borrower", collectively the "Borrowers") as detailed below.

        This Facility Letter cancels and replaces the existing
        US$55,000,000 facility provided by the Bank
        to the Parent and its Subsidiaries.

        The Schedules attached hereto form part of the terms and
        conditions of this letter.

        The Facility will be available for utilisation by the Borrowers,
        subject to the following terms and
        conditions:-

        1.  Options Available Within and Utilisation of the Facility
            --------------------------------------------------------

           The Facility may be utilised by way of  the following options
           and in  accordance  with  the  provisions  of  the  Schedules
           related thereto.-

           Sterling Money Market Loan (see Schedule A) and/or
           Sterling Overdraft (see Schedule B) and/or
           Currency Money Market Loan (the "Currency MML") (see Schedule
           C) and/or
           Foreign Currency Overdraft (see Schedule D) and/or
           Revolving Acceptance Credit (the "Credit") (see Schedule E)
           and/or
           Bonds Guarantees and Indemnities (see Schedule F) and/or
           Letters of Credit (see Schedule G) and/or
           Ancillary Facilities (see Schedule H).
PAGE
<PAGE>
           Within the Facility the aggregate of the liabilities due,
           owing or incurred thereunder shall not
           at any time exceed US$100,000,000 (or its currency
           equivalent).

           The US dollar equivalent of the currency or currencies
           utilised or available to be utilised under the Facility may
           be calculated by the Bank at any time by reference to the
           Bank's spot rate of exchange in the London Foreign Exchange
           Market for the sale of the relevant currency or currencies
           for US dollars.

           Allocations under  the Facility  that are  made available  to
           Borrowers or the Parent by branches or affiliates of the Bank
           in countries outside of  the United Kingdom will  be governed
           by the terms of the Facility as detailed herein, except where
           specifically superceded by local arrangements.

        2. Availability
           ------------

        2.1 This offer is  available to the  Parent for acceptance  until
            one Month from the date of  this letter after which date  the
            offer will  lapse unless  extended in  writing by  the  Bank.
            Acceptance is to be signified as stated in clause 18 below.

        2.2 All monies  owing  under  the  Facility  are  repayable  upon
            written demand by  the Bank  and any undrawn  portion may  be
            cancelled by the Bank at  any time.  Following demand  and/or
            cancellation, no further  utilisation may be  made under  the
            Facility.  If  demand for  repayment is made  the Bank  shall
            have in addition the  right to call for  full cash cover  for
            the amount of contingent liabilities outstanding to the  Bank
            hereunder.

           The Parent shall indemnify the Bank on demand against any
           loss or expense which the Bank
           may reasonably sustain or incur as a direct consequence of
           making such demand.

           In the absence  of demand  or cancellation by  the Bank,  the
           Facility is available for utilisation until 12 April 1996 and
           no liability  or liabilities  incurred may  extend more  than
           three  months  beyond  the   above  mentioned  expiry   date.
           However, the Bank will  be pleased to discuss  the Borrower's
           requirements shortly before that date.

        3.   Subsidiaries as Borrowers
             -------------------------

        3.1 The Parent  may  designate  any  of  its  Subsidiaries  as  a
            Borrower under this Facility Letter  by giving not less  than
            10 days  notice thereof  to the  Bank.   No such  designation
            shall take effect until such  Subsidiary and the Parent  have
            executed a deed of accession in the form set out in  Schedule
PAGE
<PAGE>
            1, and  the Bank  has  received and  found to  he  reasonably
            satisfactory  to   it   such  other   documents,   (including
            constitutional documents, board  minutes, necessary  licences
            or consents, and legal opinions) and information as the  Bank
            may reasonably require.  In addition, no Subsidiary which has
            acceded as a Borrower pursuant to this clause may utilise the
            Facility, or any option within the Facility until the  Parent
            has  made a request pursuant to clause 3.2 below and the Bank
            has agreed to such request.

        3.2 Following a request from the Parent in the form contained  in
            Schedule 2,  the Bank  may from  time to  time by  notice  in
            writing to  the  Parent allocate  to  any Subsidiary  of  the
            Parent (which has  acceded as a  Borrower pursuant to  Clause
            3.1 above) a tranche  of the Facility and/or  one or more  of
            the options  (detailed  in  clause 1)  contained  within  the
            Facility.  If the Bank does so, that tranche will not then be
            available to the Parent or other Borrowers, and the  Facility
            available to them will reduce accordingly.

        3.3 Each Borrower, by  its execution  of the  deed of  accession,
            irrevocably appoints the Parent as its agent for all purposes
            of or connected with this Agreement.  The Bank may rely  upon
            any document signed by  or on behalf of  the Parent as if  it
            had been signed by each and every other Borrower.  The Parent
            may give a good receipt for any sum payable to each and every
            other Borrower hereunder.

        4.  Interest/Fees/Charges
            ---------------------

           The interest  and/or fees,  and/or  charges payable  on  each
           option within the Facility will be calculated and  be payable
           in accordance with the relevant schedule to this Agreement.

        5 .     Interest on an Overdue Amount
                -----------------------------

        5.1If any moneys payable under this Facility are not paid when
           due by the Borrowers or the
           Parent:

           (i) interest will  be charged  on the  overdue amounts,  on a
               daily basis,  from the  due date  to the  date of  actual
               payment;

           (ii)   the amount  of such  interest  shall be  calculated  by
               reference to successive  interest periods,  (the duration
               of such interest periods shall be selected by the Bank at
               its discretion).

        5.2Interest shall be charged at the rate per annum determined by
           the Bank  to  be  equal to  1%  above  the rate  which  would
           otherwise have been applicable  to such overdue amount  under
           the provisions of  the relevant Schedule  if such amount  had
           been non-overdue principal  (except that in  the case of  any
PAGE
<PAGE>
           amount  that  does  not  have  an  applicable  interest  rate
           hereunder the rate  charged shall  be 2% per  annum over  the
           Bank's Base Rate rate current  from time to time).   Interest
           so accrued  shall be  due on  demand or  (in  the absence  of
           demand) on the  last day  of the default  interest period  in
           which it accrued and, if  unpaid, shall be compounded  on the
           last  day  of  that  and  each  successive  interest  period.
           Interest on overdue amounts  shall be charged and  compounded
           on this basis after as well as before  any judgement obtained
           hereunder.

        6.  Guarantees
            ----------

           The repayment of each  Borrower's obligations hereunder  will
           be guaranteed by the Parent  by    the execution of  a guarantee
           acceptable to the Bank in the principal sum of US$100,000,000
           plus interest and other liabilities as detailed therein.

        7.      Fees
                ----

              The Parent shall pay to the Bank the following fees:

              (i)  an arrangement fee of #65,000 upon acceptance by the
                   Parent of the Facility; and
              (ii) a facility  fee  of  #35,000  per  annum  annually  in
                   advance during the continuation of the Facility.

        8.  Cancellation
            ------------

           Any undrawn part of the amount of the Facility may be
           cancelled by the Parent in minimum amounts of US$1,000,000
           and multiples of US$500,000 subject to the Parent giving the
           Bank not less than seven days' notice in writing (such
           notice, once given, shall be irrevocable).

           Amounts which are cancelled will no longer be available for
           drawing.

        9.   Change of Circumstances
             -----------------------

           In the event of any change in applicable law or regulation or
           the existing requirements of, or any new requirements being
           imposed by, the Bank of England or other regulatory authority
           the result of which, in the sole opinion of the Bank, is to
           increase the cost to it of funding, maintaining or making
           available the Facility (or any undrawn amount thereof) or to
           reduce the effective return to the Bank then the Borrowers
           and/or, as appropriate, the Parent shall pay to the Bank,
           upon receipt of documentation evidencing such increased cost
           or reduction, as the case may be, such sum as may be
           certified by the Bank to the Borrowers and/or the Parent as
           shall compensate the Bank for such increased cost or such
           reduction.
PAGE
<PAGE>
        10. Set-off
            -------

           Any sum of  money at  any time  standing to the  credit of  a
           Borrower or the Parent with the Bank in any currency upon any
           account or otherwise (whether or not any such account is held
           in such Borrower's or the  Parent's name) or provided  to the
           Bank as  cash  cover for  any  bills and/or  any  outstanding
           liabilities under the Facility, may be applied by the Bank at
           any time  (upon  5  Business  Days  written  notice  to  such
           Borrower and the Parent) in  or towards the discharge  of any
           money or liabilities now or hereafter due, owing  or incurred
           to the Bank by such Borrower or the Parent hereunder (whether
           as principal or surety).

        11. Indemnity
            ---------

        11.1 The Parent  shall  indemnify  the Bank  on  demand  (without
           prejudice to the Bank's  other rights) for any  expense, loss
           or liability reasonably incurred  by the Bank in  consequence
           of (i) any default or delay by the Borrowers or the Parent in
           the payment of any amount when due under this letter, or (ii)
           all or  part  of  the  Facility  being  prepaid  or  becoming
           repayable otherwise than on the maturity of the  then current
           interest  period  including,  without  limitation   any  loss
           (including loss of margin), expense or liability sustained or
           incurred by  the Bank  in any  such event  in liquidating  or
           re-deploying  funds  acquired  or  committed  to  fund,  make
           available or maintain the Facility (or any part of it).

        11.2 If, for any reason, any amount payable under this letter  is
           received or recovered  in a  currency (the "other  currency")
           other than that in which it is required to  be paid hereunder
           (the "contractual  currency"), then  to the  extent that  the
           payment to  the  Bank  (when  converted  to  the  contractual
           currency at the then applicable rate of exchange) falls short
           of the amount so payable under this letter, the Parent shall,
           as a separate and independent obligation, fully indemnify the
           Bank against the amount of the shortfall.  For the purpose of
           this sub-clause the expression  "rate of exchange" means  the
           rate at which the Bank  is able as soon as  practicable after
           receipt to purchase the  contractual currency in London  with
           the other currency.

        12. Illegality
            ----------

            If, at any  time, the  Bank determines that  it is,  or will
            become unlawful or contrary to any  directives of any agency
            or any country  or state for  it to  make, fund or  allow to
            remain outstanding all or part of the Facility, and/or carry
            out  all  or  any  of  its  other  obligations  towards  the
            Borrowers and the  Parent under  this letter, then  upon the
            Bank notifying the Parent  of such event, within  30 days of
            that notification or such earlier date  (if any) as the Bank
PAGE
<PAGE>
            shall certify to  be necessary  to comply with  the relevant
            law or  directive,  the  Borrowers  and/or  the  Parent  (as
            appropriate) shall prepay any  principal amounts outstanding
            together with any accrued interest thereon.

        13. Representations and Warranties
            ------------------------------

                affecting creditors' rights and by general principles of
                equity).

            (c) Corporate Power and Authority: Guarantor: The Parent as
                -----------------------------------------
                Guarantor has the corporate power and has taken all

                constitute the legal valid and binding obligation of the
                Parent enforceable in accordance with its terms (except
                as the enforceability thereof may be limited by
                insolvency or similar laws of general application
                affecting creditors' rights and by general principles of
                equity).

            (d) Compliance with  other Instruments:  Neither  the Parent
                ----------------------------------
                nor any  Material  Subsidiary is  in  default  under any
                material agreement  to  which  it is  a  party,  and the
                execution, delivery and performance by each Borrower and
                the Parent, as  the case may  be, of  this Agreement and
                the Guarantee (a)  will not contravene  any provision of
                Applicable  Law,  (b)  will  not  conflict  with  or  be
                inconsistent with or result in any  breach of any of the
                terms,  covenants,  conditions  or   provisions  of,  or
                constitute a default under, or result in the creation or
                imposition of any Encumbrance on  any of the property or
                assets of the Parent or any Material Subsidiary pursuant
                to the terms of any  indenture, mortgage, deed to secure
                debt, deed  of  trust, or  other  material  agreement or
                instrument  to   which  the   Parent  or   any  Material
                Subsidiary is a signatory or by  which it is bound or to
                which it  may  be  subject,  (c)  will  not  violate any
                provision of the constitutional  documents of the Parent
                or any corporate  Material Subsidiary  and (d)  will not
                require any Governmental Approval.

            (e) Financial  Statements   of   Group:   The   consolidated
                -----------------------------------
                financial statements of the  Parent and its Subsidiaries
                dated 1st  January  1994  and  the  related consolidated
                statements of income  (including the notes thereto), are
                all true  and  correct  in  all  material  respects  and
                present fairly the  consolidated financial  condition of
                the Parent  and its  Subsidiaries at  that date  and the
                results of their  operations for  the year  then ending.
                To the  Parent's knowledge  neither  the Parent  nor any
                Material Subsidiary had as at  such date any significant
                liabilities, material to the Parent and its subsidiaries
                on  a  consolidated   basis,  contingent   or  otherwise
                (including liabilities for Taxes  or any unusual forward
                or long-term commitments) which were not disclosed by or
                reserved against in the financial statements referred to
                above or in the notes thereto, and there are no material
                unrealised or anticipated  losses from  any unfavourable
                commitments  of   the  Parent.     All   such  financial
                statements were  prepared in  accordance  with generally
                accepted accounting principles  applied on  a consistent
                basis  throughout  the  periods  involved.    Since  1st
                January 1994 there  has been no  material adverse change
                in the operations,  business, property or  assets of, or
                in the condition  (financial or  otherwise) or prospects
                of, the Parent and its Material Subsidiaries, taken as a
                whole.

            (f) Governmental  Approvals:  No  Governmental  Approval  is
                ------------------------
                required to authorise, or is required in connection with
                the  execution,   delivery  and   performance   of  this
                Agreement or the Guarantee.

            (g) Title to Properties:  Each of the Parent and its Material
                --------------------
PAGE
<PAGE>
                Subsidiaries has good and marketable  title to its owned
                properties,  including   the   properties   and   assets
                reflected in  the  financial statements  referred  to in
                paragraph (f)  above.    None  of  those  properties  is
                subject to  any  Encumbrance except  as  referred  to in
                those financial  statements and  possible  title defects
                and Encumbrances which do  not materially interfere with
                the use  or materially  detract from  the value  of such
                properties or  the  operations  of  the  Parent  or  the
                relevant Material Subsidiary.

            (h) Taxes :  Each of the Parent  and its Material Subsidiaries
                -----
                has filed  or  caused  to  be  filed  all  declarations,
                reports and tax  returns including,  in the  case of the
                Parent and  each  Material  Subsidiary  located  in  the
                United States, all federal and  state income tax returns
                which it is  required by law  to file, and  has paid all
                Taxes which are shown  as being due  and payable on such
                returns or on any assessments made  against it or any of
                its properties.  The accruals  and reserves on the books
                of the Parent  and its Material  Subsidiaries in respect
                of Taxes  are adequate  for  all periods.    Neither the
                Parent nor any Material Subsidiary  has any knowledge of
                any unpaid  adjustment, assessment  or any  penalties or
                interest of significance, or any  basis therefor, by any
                taxing authority  for  any  period,  except  those being
                contested in good  faith and  by appropriate proceedings
                which  effectively   stay   the   enforcement   of   any
                Encumbrance and the attachment of a penalty.

            (i) Solvency: The Parent (i) acknowledges that it will have
                ---------
                received, before the execution of its Guarantee, fair
                consideration and reasonably equivalent value for the
                obligations incurred or to be incurred by it thereunder,
                (ii) represents and warrants that after giving effect to
                such obligations (1) the present fair saleable value of
                the assets of it exceeds its liabilities in that it
                retains sufficient capital reasonably to anticipate the
                needs and risks of its ongoing business, and (2) it has
                not incurred (actually or contingently) debts beyond its
                ability to pay such debts as they mature, and that the
                present fair saleable value of its assets is greater
                than that needed to pay its probable existing debts as
                they become due.

            (j) Disclosure:   Neither  this  Agreement,  nor  any  other
                ----------
                document, certificate or statement furnished to the Bank
                by or  on behalf  of either  Borrower  or the  Parent in
                connection herewith contains  any untrue  statement of a
                material  fact  or  omits  to   state  a  material  fact
                necessary in  order  to  make  the  statements contained
                herein and  therein not  misleading.   There is  no fact
                peculiar  to  the   Parent  or   any  of   its  Material
                Subsidiaries which materially  adversely affects  or may
PAGE
<PAGE>
                (as far  as  the  Parent  can  now  foresee)  materially
                adversely affect  the business,  property or  assets, or
                financial condition  of  the  Parent  and  its  Material
                Subsidiaries taken as a whole which has not been set out

                on behalf of  the Parent,  prior to  the date  hereof in
                connection with  the transactions  contemplated  by this
                letter.

        13.2Each party providing the same shall  be deemed to repeat the
            representations and  warranties contained  in  the preceding
            sub-clause  on  each   occasion  on   which  there   is  any
            utilisation  of   the   Facility   by   reference   to   the
            circumstances then existing.

             ---------------

           Each Borrower undertakes  that the  proceeds of the  Facility
           will be used for the general working capital  purposes of the
           Borrowers.  None of such  proceeds shall be used  to purchase
           or carry,  or to  reduce or  retire or  refinance any  credit
           incurred to purchase or  carry, any margin stock  (within the
           meaning of Regulations U and X) or to extend credit to others
           for the purpose  of purchasing  or carrying  any such  margin
           stock.  If  requested by  the Bank, the  Parent will  deliver
           statements in  conformity with  the  requirements of  Federal
           Reserve Form U-l referred to in Regulation U.

             The Parent will deliver to the Bank:

             (a) within 90 days after the end of each year of the  Parent
                 and its  Subsidiaries  an audited  consolidated  balance
                 sheet of the      Parent as at  the end  of such  year, and
                 audited consolidated statements of income and cash  flow
                 of the Parent and its Subsidiaries for such year, all in
                 reasonable detail and  with the  unqualified opinion  of
                 Arthur Andersen (or  other independent certified  public
                 accountants  of  recognised  standing  selected  by  the
                 Parent and reasonably satisfactory to the Bank) together
                 with the management letter  prepared in connection  with
                 such audited  financial  statements, provided  that  the
                 Parent may make a change in its accounting principles in
                 any year,  so long  as (w)  such change  or changes  are
                 clearly reflected in  the annual audit  report, and  (x)
                 any principle has  been concurred in  by the Parent  and
                 the Parent's  independent certified  public  accountants
                 and is in accordance with generally accepted  accounting
                 principles;

<PAGE>
            (b) copies of its quarterly results on Form 10-Q and its
                audited Consolidated Profit and Loss Account and Balance
                Sheet (in the form of an Annual Report and/or form 10-K,
                as appropriate) not later than 45 days from the end of
                each quarter and 90 days from the end of each accounting
                reference period respectively; and

            (c) with reasonable  promptness,  such  further  information
                regarding the business  affairs and financial  condition
                of the Parent or any Material Subsidiary as the Bank may
                reasonably request.

        14.3 Maintenance of Books: Inspection of Property and Records
             --------------------------------------------------------

             The Parent shall and shall procure that each of its Material
             Subsidiaries shall prepare or cause to be prepared (a) its
             annual statements and reports in accordance with generally
             accepted accounting principles and permit any person
             designated by the Bank to visit and inspect any of its
             properties, corporate books and financial records, and to
             discuss its accounts, affairs and finance with the principal
             officers of the Parent and such Material Subsidiary during
             reasonable business hours, and upon reasonable prior notice,
             from time to time, as the Bank may reasonably request and
             (b) its interim statements and reports in accordance with
             methods historically used by such Material Subsidiary, as
             the case may be, as such methods have yielded financial
             information which has historically not required material
             annual adjustments to bring such information into compliance
             with generally accepted accounting principles.

        14.4 Maintenance of Properties
             -------------------------

             The Parent shall and shall procure that each of its Material
             Subsidiaries shall maintain, preserve, protect and keep,  or
             cause to be maintained,  preserved, protected and kept,  its
             properties and every  part thereof in  good repair,  working
             order and  condition, and  from time  to time  will make  or
             cause to be made all  needful and proper repairs,  renewals,
             replacements,  extensions,   additions,   betterments,   and
             improvements thereto,  so    that the  business carried  on in
             connection therewith  may  be  properly  and  advantageously
             conducted at  all times  Provided that  the Parent  and  its
             Material Subsidiaries  shall not  be  obliged to  repair  or
             replace any such  properties which have  become obsolete  or
             unsuitable or inadequate for the purpose for which they  are
             used.

        14.5 Maintenance of Insurance
             ------------------------

             The Parent shall and shall procure that each of its Material
             Subsidiaries   shall   maintain   liability   and   worker's
             compensation insurance  (or maintain  a legally  sufficient,
             fully funded, programme  of self-insurance against  worker's
PAGE
<PAGE>
             compensation  liabilities),   adequate  insurance   on   its
             properties against such hazards and in at least such amounts
             as is customary in the business  and, at the request of  the
             Bank,  the  Parent  will  forthwith  deliver  an   officer's
             certificate specifying the details of the insurance then  in
             effect.

        14.6 Taxes
             -----

             The Parent shall and shall procure that each of its Material
             Subsidiaries shall pay and discharge all Taxes prior to  the
             date on which         penalties attach thereto,  and will  pay all
             Taxes which, if unpaid, might become an Encumbrance upon any
             of its property  Provided that the  Parent and its  Material
             Subsidiaries shall not be required to pay and discharge  any
             such Tax so long as the legality or amount thereof shall  be
             promptly  contested  in  good   faith  and  by   appropriate
             proceedings which effectively  stay the  enforcement of  any
             Encumbrance and the attachment of  a penalty and the  Parent
             or such Material Subsidiary, as the case may be, shall  have
             set aside appropriate reserves  therefor in accordance  with
             generally accepted accounting principles.

        14.7 Existence and Status
             --------------------

             The Parent and each of its Material Subsidiaries which is  a
             corporation  shall  maintain  its  corporate  existence  and
             (where relevant) good standing in its state of incorporation
             and its qualification and (where relevant) good standing  as
             a  foreign  corporation  in  all  jurisdictions  where   its
             ownership of property or its business activities cause  such
             qualification to be required.

        14.8 Litigation
             ----------

             The Parent  shall give  prompt  notice to  the Bank  of  any
             material pending  legal proceedings.   For  the purposes  of
             this Clause 14.8, only pending legal proceedings which would
             be required to be reported by the Parent for Securities  and
             Exchange Commission Filings need be reported to the Bank.

        14.9 Stockholder Reports, etc
             ------------------------

             Promptly after  the  same  are available,  the  Parent  will
             provide to the Bank copies of all publicly available current
             reports on Form 8-K, proxy statements and prospectuses filed

        15.  Payments and Gross-Up
             ---------------------
PAGE
<PAGE>

        15. I     All payments  by  a  Borrower,  whether  of  principal,
             interest or otherwise, shall be  made to the Bank not  later
             than 12 noon (London time) on the due date in same day funds
             (or as  otherwise expressly  agreed  by the  Bank),  without
             set-off  or  counterclaim  and  free  of  any  deduction  or
             withholding whatsoever, including  without prejudice to  the
             generality of  the foregoing,  for or  on account  of  Taxes
             unless that Borrower  is required  by law to  make any  such
             payments subject to deduction  or withholding on account  of
             Taxes, in which  case the  sum payable by  that Borrower  in
             respect of which such  deduction or withholding is  required
             to be made  shall be  increased to the  extent necessary  to
             ensure  that,  after  the   making  of  such  deduction   or
             withholding, the Bank  receives and retains  (free from  any
             liability in respect of any such deduction or withholding) a
             net sum equal to the sum which it would have received and so
             retained had no such deduction  or withholding been made  or
             required to be made.

        15.2 Without prejudice to the provisions  of Clause I5.1, if  the
             Bank is required by  law to make any  payment on account  of
             Taxes (other  than  Taxes  on its  overall  net  income)  or
             otherwise  on  or  in  relation  to  any  sum  received   or
             receivable by  the  Bank  hereunder,  or  any  liability  in
             respect of any such payment  is imposed, levied or  assessed
             against the Bank, the relevant Borrower shall, on demand  by
             the  Bank,  indemnify  the  Bank  against  such  payment  or
             liability together with any interest penalties and  expenses
             payable or incurred in  connection therewith (except to  the
             extent that  such interest  penalties and  expenses  results
             from the late settlement of such payment or liability by the
             Bank).

        15.3 If the Bank intends to make a claim pursuant to clause 15.2,
             it shall notify the relevant Borrower of the event by reason
             of which  it  is entitled  to  do  so and  provide  to  that
             Borrower in reasonable  detail a calculation  of the  amount
             claimed Provided that nothing herein shall require the  Bank
             to disclose any information relating to the organisation  of
             its affairs  which  the Bank  shall,  in its  sole  opinion,
             consider to be confidential.

                                   ----------

        Sterling Money Market Loan

        The Sterling Money Market Loan may be drawn in one or more
        amounts, each drawing to be a minimum amount of #500,000 and
        multiples of #100,000 thereafter for periods of 30,60 or 90 days
        at the Borrower's option or other mutually agreed period but no
        drawing shall be made for an interest period with a maturity date
        of more than three months beyond the expiry date detailed in
        clause 2.2 of the letter.

        When wishing to draw under the Sterling Money Market Loan, the
        Borrower should telephone the account holding branch of the Bank
        on or shortly before the day on which funds are required stating
        the amount of the drawing, the period required and giving
        instructions for payment of the funds.  In the event these
        instructions do not stipulate that the funds must be credited to
        the Borrower's current account with the account holding Branch
        such instructions must be confirmed by letter to the account
        holding Branch at the earliest opportunity.

        The rate of interest on each drawing will include the Bank's
        margin of 0.45% per annum added to the cost of funds to the Bank
        (such cost of funds to be conclusively determined by the Bank and
        shall include any associated costs resulting from requirements of
        the Bank of England or other governmental authorities or
        agencies, whether having the force of law or otherwise, affecting
        the conduct of the Bank's business) for the period of the
        drawing.  Interest will be payable without deduction at six
        monthly intervals if appropriate and at the maturity of each
        drawing, and calculated on the basis of actual days elapsed over
        a 365 day year.

        Each drawing, together with interest thereon, will be repaid on

        the account holding branch.

        Sterling Overdraft
        ------------------

        The Sterling Overdraft will be available on the Borrower's
        current account at the Branch with interest charged at a rate of
        1% per annum over the Bank's Base Rate current from time to time.

        Borrower's current account at the Branch quarterly in arrears in
        March, June, September and December each year or at such other
        times as may be determined by the Bank, and such interest will be
        calculated on the basis of actual days elapsed over a 365 day
        year.

                                   ----------

        Currency Money Market Loan
        --------------------------

        This option relates to a short term loan in any currency (other
        than sterling) which is freely transferable and convertible into
        sterling and is available to the Bank in the relevant amount for
        the relevant period in the normal course of business on the
        London Inter-Bank market.  The Bank shall be sole arbitor of the
        availability of such currencies.

        The short term currency loans may be drawn in one or more
        amounts, each drawing to be a minimum amount of the currency
        equivalent of US$500,000.  Larger drawings shall be in amounts
        which are mutually agreeable and drawings shall be for periods up
        to a maximum of six months at the Borrower's option or other
        mutually agreed periods but no drawing should be made for an
        interest period with a maturity date of more than three months
        beyond the expiry date detailed in clause 2.2 of the letter.

        When drawings are to be made, the Borrower should telephone the
        account holding branch of the Bank two business days before the
        business day on which funds are required stating the amount of
        the drawing, the period required and giving instructions for
        payment of the funds.  In the event these instructions do not
        stipulate that the funds must be credited to the Borrower's
PAGE
<PAGE>
        current account with the Branch, such instructions must be
        confirmed by letter to the Branch at the earliest opportunity.

        The interest rate on each drawing will include the Bank's margin
        of 0.45% per annum added to the cost of funds to the Bank (such
        cost of funds to be conclusively determined by the Bank) which
        will be dependent upon the conditions prevailing in the relevant
        London financial markets for the period of the drawing.  Interest
        will be payable without deduction at six monthly intervals, if
        appropriate, and at the maturity of each drawing, and calculated
        on the basis of actual days elapsed over a 360 day year.

        Each drawing, together with interest thereon, will be repaid on
        its maturity date in the currency in which such drawing is
        outstanding in immediately available freely convertible and
        transferable funds without any set-off or counterclaim and free
        of any deduction or withholding on any ground, to such bank or
        branch of the Bank as the Bank may specify.  In the event of the
        Borrower being compelled by law to make any such deduction or
        withholding, the Borrower will pay to the Bank such additional
        amount(s) as are required to ensure that the Bank receives and
        retains a net amount equal to the full amount which it would have
        received if no such deduction or withholding had been made.

        For the purposes of this letter a "business day" shall mean a day
                            ----
        on which the relevant London financial markets are open for
        dealings in eurocurrency deposits between banks and, in addition,
        so far as concerns a day on which a payment falls to be made
        hereunder, a day on which banks in the relevant principal
        financial centre (as determined by the Bank) for the relevant
        currency are open for dealings in such currency.  Should any
        requirements under this letter fall due on a date which is not a
        business day, then such date shall be extended to the next
        business day.

        Revolving Acceptance Credit
        ---------------------------

        To enable drawings to be made under the Revolving Acceptance
        Credit (the "Credit"), the Borrower should either:
PAGE
<PAGE>
        (I)  forward bills to the Branch to be in the Branch's hands at
        least four business days before the     funds are required.
        Bills should be drawn by the Borrower on Barclays Bank PLC, Head
        Office,   54 Lombard Street, London EC3P 3AH for fixed periods of
        30,60 or 90 days except that no    period may be selected which
        would mature more than 90 days after the expiry date detailed in 
             clause 2 of this letter.  If the selected maturity date is a
        non-business day, bills should be drawn      to mature on the
        following business day.  Individual bills should be drawn in
        amounts of #50,000  and should be made to the Bank's order and
        claused "Drawn against purchases of electronic    security
        systems" or

        (ii) forward a supply of bills to the Branch drawn as in (i)
             above, except that the dates will be left blank.  The branch
             will arrange for the supply of bills to be held by the
             Bank's Global Treasury Services Office in London ("GTS"),
             and for the dates to be completed in accordance with the
             Borrower's oral instructions when drawings are required.

        When wishing to draw under the Credit, the Borrower should
        telephone the Bank's dealers at GTS on 071 696 2496 before 12.00
        noon on the day on which funds are required, stating the amount
        required and the period, and agreeing the discount rate quoted.

        The Bank will accept the bills and will, at its option, either
        (i) discount the bills itself in which case the rate of discount
        will be the then current offer rate as quoted by the Bank for
        such bills in the London Discount Market, or (ii) offer the bills
        for discount as agent on the Borrower's behalf in the London
        Discount Market at the discount rate prevailing in such market at
        the time when discount is effected.  The proceeds after discount
        and acceptance commission will be credited to the Borrower's
        current account at the Branch.

        Acceptance commission payable at the time of acceptance will be
        charged at the rate of 0.5% per annum on the face value of each
        draft presented and will be deducted from the proceeds after
        discount.

        The Bank will debit the Borrower's current account with the face
        value of each draft upon its maturity date.  The Credit is
        revolving, however, and it will be open to the Borrower within
        the validity and terms of the Facility to present further bills
        in accordance with this clause.

        By its acceptance of the Facility, the Borrower undertakes that
        during the validity of the Credit it will ensure that there are
        sufficient purchases to cover the amounts drawn during the period
        for which such bills are drawn and which are not the subject of
        other financing arrangements.  The Borrower will provide a
        certificate to this effect, signed by an official authorised to
        draw bills, if requested by the Bank in writing.
PAGE
<PAGE>
        The acceptance of a bill shall give rise to a debt from the
        Borrower to the Bank equal to the face value of such bill, which
        debt shall be due for payment on the maturity of such bill.

                           THERMO ELECTRON CORPORATION

                     RESTATED STOCK HOLDING ASSISTANCE PLAN

        SECTION 1.   Purpose.

             The purpose of this Plan is to benefit Thermo Electron
        Corporation (the "Company") and its stockholders by encouraging
        Key Employees to acquire and maintain share ownership in the
        Company, by increasing such employees' proprietary interest in
        promoting the growth and performance of the Company and its
        subsidiaries and by providing for the implementation of the Stock
        Holding Policy.  

        SECTION 2.     Definitions.

             The following terms, when used in the Plan, shall have the
        meanings set forth below:

             Committee:   The Human Resources Committee of the Board of
        Directors of the Company as appointed from time to time.

             Common Stock:   The common stock of the Company and any
        successor thereto.

             Company:   Thermo Electron Corporation, a Delaware
        corporation.

             Stock Holding Policy:   The Stock Holding Policy of the
        Company, as adopted by the Committee and as in effect from time
        to time.

             Key Employee:   Any employee of the Company or any of its
        subsidiaries, including any officer or member of the Board of
        Directors who is also an employee, as designated by the
        Committee, and who, in the judgment of the Committee, will be in
        a position to contribute significantly to the attainment of the
        Company's strategic goals and long-term growth and prosperity.

             Loans:   Loans extended to Key Employees by the Company
        pursuant to this Plan.

             Plan:   The Thermo Electron Corporation Stock Holding
        Assistance Plan, as amended from time to time.

        SECTION 3.     Administration.

             The Plan and the Stock Holding Policy shall be administered
        by the Committee, which shall have authority to interpret the
        Plan and the Stock Holding Policy and, subject to their
        provisions, to prescribe, amend and rescind any rules and
        regulations and to make all other determinations necessary or
        desirable for the administration thereof.  The Committee's
PAGE
<PAGE>
        interpretations and decisions with regard to the Plan and the
        Stock Holding Policy and such rules and regulations as may be
        established thereunder shall be final and conclusive.  The
        Committee may correct any defect or supply any omission or
        reconcile any inconsistency in the Plan or the Stock Holding
        Policy, or in any Loan in the manner and to the extent the
        Committee deems desirable to carry it into effect.  No member of
        the Committee shall be liable for any action or omission in
        connection with the Plan or the Stock Holding Policy that is made
        in good faith.

        SECTION 4.     Loans and Loan Limits.

             The Committee has determined that the provision of Loans
        from time to time to Key Employees in such amounts as to cause
        such Key Employees to comply with the Stock Holding Policy is, in
        the judgment of the Committee, reasonably expected to benefit the
        Company and authorizes the Company to extend Loans from time to
        time to Key Employees in such amounts as may be requested by such
        Key Employees in order to comply with the Stock Holding Policy.
        Such Loans may be used solely for the purpose of acquiring Common
        Stock (other than upon the exercise of stock options or under
        employee stock purchase plans) in open market transactions or
        from the Company.

             Each Loan shall be full recourse and evidenced by a
        non-interest bearing promissory note substantially in the form
        attached hereto as Exhibit A (the "Note") and maturing in
        accordance with the provisions of Section 6 hereof, and
        containing such other terms and conditions, which are not
        inconsistent with the provisions of the Plan and the Stock
        Holding Policy, as the Committee shall determine in its sole and
        absolute discretion.

        SECTION 5.     Federal Income Tax Treatment of Loans.

             For federal income tax purposes, interest on Loans shall be
        imputed on any interest free Loan extended under the Plan.  A Key
        Employee shall be deemed to have paid the imputed interest to the
        Company and the Company shall be deemed to have paid said imputed
        interest back to the Key Employee as additional compensation.
        The deemed interest payment shall be taxable to the Company as
        income, and may be deductible to the Key Employee to the extent
        allowable under the rules relating to investment interest.  The
        deemed compensation payment to the Key Employee shall be taxable
        to the employee and deductible to the Company, but shall also be
        subject to employment taxes such as FICA and FUTA.

        SECTION 6.     Maturity of Loans.

             Each Loan to a Key Employee hereunder shall be due and
        payable on demand by the Company.  If no such demand is made,
        then each Loan shall mature and the principal thereof shall
        become due and payable on the fifth anniversary of the date of
PAGE
<PAGE>
        the Loan, provided that the Committee may, in its sole and
        absolute discretion, authorize such other maturity and repayment
        schedule as the Committee may determine.  Each Loan shall also
        become immediately due and payable in full, without demand, upon
         the occurrence of any of the events set forth in the Note;
        provided that the Committee may, in its sole and absolute
        discretion, authorize an extension of the time for repayment of a
        Loan upon such terms and conditions as the Committee may
        determine.

        SECTION 7.     Amendment and Termination of the Plan.

             The Committee may from time to time alter or amend the Plan
        or the Stock Holding Policy in any respect, or terminate the Plan
        or the Stock Holding Policy at any time.  No such amendment or
        termination, however, shall alter or otherwise affect the terms
        and conditions of any Loan then outstanding to Key Employee
        without such Key Employee's written consent, except as otherwise
        provided herein or in the promissory note evidencing such Loan.

        SECTION 8.     Miscellaneous Provisions.

             (a)  No employee or other person shall have any claim or
        right to receive a Loan under the Plan, and no employee shall
        have any right to be retained in the employ of the Company due to
        his or her participation in the Plan.

             (b)  No Loan shall be made hereunder unless counsel for the
        Company shall be satisfied that such Loan will be in compliance
        with applicable federal, state and local laws.

             (c)  The expenses of the Plan shall be borne by the Company.

             (d)  The Plan shall be unfunded, and the Company shall not
        be required to establish any special or separate fund or to make
        any other segregation of assets to assure the making of any Loan
        under the Plan.

             (e)  Except as otherwise provided in Section 7 hereof, by
        accepting any Loan under the Plan, each Key Employee shall be
        conclusively deemed to have indicated his acceptance and
        ratification of, and consent to, any action taken under the Plan
        or the Stock Holding Policy by the Company, the Board of
        Directors of the Company or the Committee.

             (f)  The appropriate officers of the Company shall cause to
        be filed any reports, returns or other information regarding
        Loans hereunder, as may be required by any applicable statute,
        rule or regulation.

        SECTION 9.     Effective Date.

             The Plan and the Stock Holding Policy shall become effective
        upon approval and adoption by the Committee.

        waiver of the  same or any  other right on  any future  occasion.
        The  Employee  hereby  waives  presentment,  demand,  notice   of
        prepayment,  protest  and  all  other  demands  and  notices   in

                                                          EXHIBIT 10.46

                           THERMO ELECTRON CORPORATION

            THERMEDICS DETECTION INC. NONQUALIFIED STOCK OPTION PLAN


        1.   Purpose

             This Nonqualified Stock Option Plan (the "Plan") is intended
        to encourage  ownership of  Common Stock,  $0.01 par  value  (the
        "Common Stock"), of Thermedics Detection  Inc.   ("Subsidiary"), a
        subsidiary of  Thermo Electron  Corporation   (the  "Company"), by
        persons selected  by  the  Board of  Directors  (or  a  committee
        thereof) in its sole  discretion, including directors,  executive
        officers, key employees  and consultants of  the Company and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan

             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        3.   Stock Subject to Plan

             At no time shall  the number of shares  of the Common  Stock
        then outstanding  which  are  attributable  to  the  exercise  of
        options granted under  the Plan  plus the number  of shares  then
        issuable upon the exercise  of outstanding options granted  under
        the  Plan  exceed  150,000 shares, subject however, to the
        provisions of paragraph 11 of the Plan.  Shares to be issued upon
        the exercise of options granted under the Plan shall be shares of
        Subsidiary beneficially  owned by  the Company.   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.

        4.   Administration

             The  Plan  shall  be   administered  by  a  committee   (the
        "Committee") composed of the members of the Board of Directors of
        the Company,  no  member  of  which shall  act  upon  any  matter
        exclusively affecting  any option  granted or  to be  granted  to
        himself or herself under the Plan.  Subject to the provisions  of
        the Plan, the  Committee shall  have complete  authority, in  its
        discretion, to make the following determinations with respect  to
        each option to  be granted  by the Company:   (a)  the person  to
        receive the option (the "Optionee"); (b) the time of granting the
        option; (c) the number of shares subject thereto; (d) the  option
        price; (e) the option period; and (f) the terms of the option and
        form of option agreement (which need not be identical, but  which
        shall conform to the applicable terms and conditions of the  Plan
        and contain such other provisions as the Board of Directors deems
PAGE
<PAGE>
        advisable and not inconsistent  with the Plan).   In making  such
        determinations, the Committee may take into account the nature of
        the  services  rendered  by  the  Optionees,  their  present  and
        potential contributions to the success of the Company and/or  one
        or more  of  its subsidiaries,  and  such other  factors  as  the
        Committee in its discretion shall deem relevant.  Subject to  the
        provisions of the  Plan, the Committee  shall also have  complete
        authority to interpret the Plan, to prescribe, amend, and rescind
        rules and regulations relating to it, to determine the terms  and
        provisions of the respective option agreements (which need not be
        identical), and  to make  all other  determinations necessary  or
        advisable for the  administration of the  Plan.  The  Committee's
        determinations on the  matters referred  to in  this paragraph  4
        shall be conclusive.

        5.   Eligibility

             An option  may be  granted  to any  person selected  by  the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting  of an  option  shall take  place at  the  time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of  an option be regarded as  taking
        place at the time when a written option agreement shall have been
        duly executed and delivered  by or on behalf  of the Company  and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things,  that it does not confer  upon
        an Optionee any right  to continue in the  employ of the  Company
        and/or one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company if  the Optionee  is a  director, or  to
        terminate the  services of  the  Optionee if  the Optionee  is  a
        consultant.

        7.   Option Period

             An option  may become  exercisable  immediately or  in  such
        installments, cumulative or noncumulative,  as the Committee  may
        determine.  

        8.   Exercise of Option

             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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  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, Subsidiary  or  the  Optionee  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.

        9.   Transferability

             Except as may be  authorized by the  Committee , in its sole
        discretion, no  Option   may be transferred other than by will or
        the laws of  descent and  distribution, and  during a  Optionee's
        lifetime an option    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). The Committee   
        may, in its  discretion, determine  the extent  to which  options
        granted to an Optionee shall be transferable, and such provisions
        permitting or acknowledging  transfer shall be  set forth in  the
        written agreement evidencing the option executed and delivered by
        or on behalf of the Company and the Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee,  in its  sole discretion,  may determine  the
        manner in which options shall vest, the rights of the Company  to
        repurchase the shares issued upon the exercise of any option  and
        the manner in which such rights  shall lapse, and the terms  upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right  to accelerate the date  of exercise of  any
        installment  or  to  accelerate   the  lapse  of  the   Company's
        repurchase rights.   All of such  terms shall be  specified in  a
        written option agreement executed and  delivered by or on  behalf
        of the Company  and the  Optionee to  whom such  option shall  be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the  event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction  in  the number  of  shares of  the  Common  Stock
        occurring after  the  date of  the  agreement and  prior  to  the
        exercise in full of  the option, the number  of shares for  which
        the option may thereafter  be exercised shall be  proportionately
        adjusted and the price to be  paid for each share subject to  the
        option shall be  proportionately adjusted.   Each such  agreement
PAGE
<PAGE>
        shall also provide that in case of any reclassification or change
        of outstanding  shares of  the Common  Stock or  in case  of  any
        consolidation or  merger  of  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
        the option,  be entitled  to  receive shares  of stock  or  other
        securities in its  place equivalent  in kind and  value to  those
        shares which  he would  have  received if  he had  exercised  the
        option  in  full  immediately  prior  to  such  reclassification,
        change,  consolidation,  merger,  sale  or  conveyance  and   had
        continued to hold the shares subject to the option (together with
        all other  shares,  stock  and securities  thereafter  issued  in
        respect thereof)  to the  time  of the  exercise of  the  option;
        provided , that if any recapitalization is to be effected  through
        an increase  in the  par value  of the  Common Stock  without  an
        increase in  the number  of authorized  shares and  such new  par
        value will  exceed the  option price  under such  agreement,  the
        Company   shall   notify   the   Optionee   of   such    proposed
        recapitalization, and  the Optionee  shall then  have the  right,
        exercisable at any time  prior to such recapitalization  becoming
        effective, to purchase all  of the shares  subject to the  option
        which  he  has  not  theretofore  purchased  (anything  in   such
        agreement to the contrary  notwithstanding), but if the  Optionee
        fails to exercise such right before such recapitalization becomes
        effective,  the  option  price  under  such  agreement  shall  be
        appropriately  adjusted.    Each  such  agreement  shall  further
        provide that upon dissolution  or liquidation of Subsidiary,  the
        option shall  terminate, but  the  Optionee (if  at the  time  an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall  have the  right, immediately  prior to  such
        dissolution or liquidation,  to exercise the  option to the  full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share  with respect to which the  option
        has  been  exercised  prior  to   the  effective  date  of   such
        adjustment; and that no fraction of a share or fractional  shares
        shall be purchasable or deliverable under such agreement, but  in
        the event  any  adjustment thereunder  of  the number  of  shares
        covered by  the  option shall  cause  such number  to  include  a
        fraction of  a share,  such  fraction shall  be adjusted  to  the
        nearest smaller whole number of shares.  In the event of  changes
        in the outstanding Common Stock by reason of any stock  dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the  Common Stock  of the nature  contemplated by  this
        paragraph 11, the number of shares of Common Stock available  for
        the purpose of the Plan as stated in paragraph 3 hereof shall  be
        correspondingly adjusted by the Committee.

        12.  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
PAGE
<PAGE>
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  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 satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising  an option, at  the request of  the
        Company, will  be  required  to give  a  representation  in  form
        satisfactory  to  counsel  for  the  Company  that  he  will  not
        transfer, sell or otherwise dispose  of the shares received  upon
        exercise of  the  option  at  any time  purchased  by  him,  upon
        exercise of any portion  of the option, in  a manner which  would
        violate  the  Securities  Act  of  1933,  as  amended,  and   the
        regulations of the Securities and Exchange Commission  thereunder
        and the Company  may, if required  or at its  discretion, make  a
        notation on any certificates issued  upon exercise of options  to
        the effect that  such certificate may  not be transferred  except
        after  receipt  by   the  Company  of   an  opinion  of   counsel
        satisfactory to  it to  the effect  that such  transfer will  not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments  of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect  to
        any shares issued upon  exercise of options  under the Plan  (the
        "withholding requirements").  The  Committee will have the  right
        to require that the Optionee or other appropriate person remit to
        the Company  an  amount  sufficient to  satisfy  the  withholding
        requirements, or  make  other arrangements  satisfactory  to  the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding  is required, the Committee  may
        permit the Optionee or  such other person to  elect at such  time
        and in such manner as the Committee 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 requirements.

        16.  Termination and Amendment of Plan

             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,
PAGE
<PAGE>
        the Board  of  Directors  may not  effect  such  modification  or
        amendment without such approval.

             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.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2008   and no options  shall be granted
        hereunder thereafter.

        the Company,  no  member  of  which shall  act  upon  any  matter
        exclusively affecting  any option  granted or  to be  granted  to
        himself or herself under the Plan.  Subject to the provisions  of
        the Plan, the  Committee shall  have complete  authority, in  its
        discretion, to make the following determinations with respect  to
        each option to  be granted  by the Company:   (a)  the person  to
        receive the option (the "Optionee"); (b) the time of granting the
        option; (c) the number of shares subject thereto; (d) the  option
        price; (e) the option period; and (f) the terms of the option and
        form of option agreement (which need not be identical, but  which
        shall conform to the applicable terms and conditions of the  Plan
        and contain such other provisions as the Board of Directors deems
PAGE
<PAGE>
        advisable and not inconsistent  with the Plan).   In making  such
        determinations, the Committee may take into account the nature of
        the  services  rendered  by  the  Optionees,  their  present  and
        potential contributions to the success of the Company and/or  one
        or more  of  its subsidiaries,  and  such other  factors  as  the
        Committee in its discretion shall deem relevant.  Subject to  the
        provisions of the  Plan, the Committee  shall also have  complete
        authority to interpret the Plan, to prescribe, amend, and rescind
        rules and regulations relating to it, to determine the terms  and
        provisions of the respective option agreements (which need not be
        identical), and  to make  all other  determinations necessary  or
        advisable for the  administration of the  Plan.  The  Committee's
        determinations on the  matters referred  to in  this paragraph  4
        shall be conclusive.

        5.   Eligibility

             An option  may be  granted  to any  person selected  by  the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting  of an  option  shall take  place at  the  time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of  an option be regarded as  taking
        place at the time when a written option agreement shall have been
        duly executed and delivered  by or on behalf  of the Company  and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things,  that it does not confer  upon
        an Optionee any right  to continue in the  employ of the  Company
        and/or one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company if  the Optionee  is a  director, or  to
        terminate the  services of  the  Optionee if  the Optionee  is  a
        consultant.

        7.   Option Period

             An option  may become  exercisable  immediately or  in  such
        installments, cumulative or noncumulative,  as the Committee  may
        determine.  

        8.   Exercise of Option

             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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  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, Subsidiary  or  the  Optionee  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.

        9.   Transferability

             Except as may be  authorized by the  Committee , in its sole
        discretion, no  Option   may be transferred other than by will or
        the laws of  descent and  distribution, and  during a  Optionee's
        lifetime an option    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). The Committee   
        may, in its  discretion, determine  the extent  to which  options
        granted to an Optionee shall be transferable, and such provisions
        permitting or acknowledging  transfer shall be  set forth in  the
        written agreement evidencing the option executed and delivered by
        or on behalf of the Company and the Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee,  in its  sole discretion,  may determine  the
        manner in which options shall vest, the rights of the Company  to
        repurchase the shares issued upon the exercise of any option  and
        the manner in which such rights  shall lapse, and the terms  upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right  to accelerate the date  of exercise of  any
        installment  or  to  accelerate   the  lapse  of  the   Company's
        repurchase rights.   All of such  terms shall be  specified in  a
        written option agreement executed and  delivered by or on  behalf
        of the Company  and the  Optionee to  whom such  option shall  be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the  event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction  in  the number  of  shares of  the  Common  Stock
        occurring after  the  date of  the  agreement and  prior  to  the
        exercise in full of  the option, the number  of shares for  which
        the option may thereafter  be exercised shall be  proportionately
        adjusted and the price to be  paid for each share subject to  the
        option shall be  proportionately adjusted.   Each such  agreement
PAGE
<PAGE>
        shall also provide that in case of any reclassification or change
        of outstanding  shares of  the Common  Stock or  in case  of  any
        consolidation or  merger  of  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
        the option,  be entitled  to  receive shares  of stock  or  other
        securities in its  place equivalent  in kind and  value to  those
        shares which  he would  have  received if  he had  exercised  the
        option  in  full  immediately  prior  to  such  reclassification,
        change,  consolidation,  merger,  sale  or  conveyance  and   had
        continued to hold the shares subject to the option (together with
        all other  shares,  stock  and securities  thereafter  issued  in
        respect thereof)  to the  time  of the  exercise of  the  option;
        provided , that if any recapitalization is to be effected  through
        an increase  in the  par value  of the  Common Stock  without  an
        increase in  the number  of authorized  shares and  such new  par
        value will  exceed the  option price  under such  agreement,  the
        Company   shall   notify   the   Optionee   of   such    proposed
        recapitalization, and  the Optionee  shall then  have the  right,
        exercisable at any time  prior to such recapitalization  becoming
        effective, to purchase all  of the shares  subject to the  option
        which  he  has  not  theretofore  purchased  (anything  in   such
        agreement to the contrary  notwithstanding), but if the  Optionee
        fails to exercise such right before such recapitalization becomes
        effective,  the  option  price  under  such  agreement  shall  be
        appropriately  adjusted.    Each  such  agreement  shall  further
        provide that upon dissolution  or liquidation of Subsidiary,  the
        option shall  terminate, but  the  Optionee (if  at the  time  an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall  have the  right, immediately  prior to  such
        dissolution or liquidation,  to exercise the  option to the  full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share  with respect to which the  option
        has  been  exercised  prior  to   the  effective  date  of   such
        adjustment; and that no fraction of a share or fractional  shares
        shall be purchasable or deliverable under such agreement, but  in
        the event  any  adjustment thereunder  of  the number  of  shares
        covered by  the  option shall  cause  such number  to  include  a
        fraction of  a share,  such  fraction shall  be adjusted  to  the
        nearest smaller whole number of shares.  In the event of  changes
        in the outstanding Common Stock by reason of any stock  dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the  Common Stock  of the nature  contemplated by  this
        paragraph 11, the number of shares of Common Stock available  for
        the purpose of the Plan as stated in paragraph 3 hereof shall  be
        correspondingly adjusted by the Committee.

        12.  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
PAGE
<PAGE>
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  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 satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising  an option, at  the request of  the
        Company, will  be  required  to give  a  representation  in  form
        satisfactory  to  counsel  for  the  Company  that  he  will  not
        transfer, sell or otherwise dispose  of the shares received  upon
        exercise of  the  option  at  any time  purchased  by  him,  upon
        exercise of any portion  of the option, in  a manner which  would
        violate  the  Securities  Act  of  1933,  as  amended,  and   the
        regulations of the Securities and Exchange Commission  thereunder
        and the Company  may, if required  or at its  discretion, make  a
        notation on any certificates issued  upon exercise of options  to
        the effect that  such certificate may  not be transferred  except
        after  receipt  by   the  Company  of   an  opinion  of   counsel
        satisfactory to  it to  the effect  that such  transfer will  not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments  of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect  to
        any shares issued upon  exercise of options  under the Plan  (the
        "withholding requirements").  The  Committee will have the  right
        to require that the Optionee or other appropriate person remit to
        the Company  an  amount  sufficient to  satisfy  the  withholding
        requirements, or  make  other arrangements  satisfactory  to  the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding  is required, the Committee  may
        permit the Optionee or  such other person to  elect at such  time
        and in such manner as the Committee 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 requirements.

        16.  Termination and Amendment of Plan

             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,
PAGE
<PAGE>
        the Board  of  Directors  may not  effect  such  modification  or
        amendment without such approval.

             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.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2008   and no options  shall be granted
        hereunder thereafter.




                                                EXHIBIT 10.48
                           THERMO ELECTRON CORPORATION

            THERMO VISION CORPORATION NONQUALIFIED STOCK OPTION PLAN


        1.   Purpose

             This Nonqualified Stock Option Plan (the "Plan") is intended
        to encourage  ownership of  Common Stock,  $0.01 par  value  (the
        "Common Stock"), of Thermo Vision  Corporation    ("Subsidiary"), a
        subsidiary of  Thermo Electron  Corporation   (the  "Company"), by
        persons selected  by  the  Board of  Directors  (or  a  committee
        thereof) in its sole  discretion, including directors,  executive
        officers, key employees  and consultants of  the Company and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan

             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        3.   Stock Subject to Plan

             At no time shall  the number of shares  of the Common  Stock
        then outstanding  which  are  attributable  to  the  exercise  of
        options granted under  the Plan  plus the number  of shares  then
        issuable upon the exercise  of outstanding options granted  under
        the  Plan  exceed  150,000  shares, subject however, to the
        provisions of paragraph 11 of the Plan.  Shares to be issued upon
        the exercise of options granted under the Plan shall be shares of
        Subsidiary beneficially  owned by  the Company.   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.

        4.   Administration

             The  Plan  shall  be   administered  by  a  committee   (the
        "Committee") composed of the members of the Board of Directors of
        the Company,  no  member  of  which shall  act  upon  any  matter
        exclusively affecting  any option  granted or  to be  granted  to
        himself or herself under the Plan.  Subject to the provisions  of
        the Plan, the  Committee shall  have complete  authority, in  its
        discretion, to make the following determinations with respect  to
        each option to  be granted  by the Company:   (a)  the person  to
        receive the option (the "Optionee"); (b) the time of granting the
        option; (c) the number of shares subject thereto; (d) the  option
        price; (e) the option period; and (f) the terms of the option and
        form of option agreement (which need not be identical, but  which
        shall conform to the applicable terms and conditions of the  Plan
        and contain such other provisions as the Board of Directors deems
PAGE
<PAGE>
        advisable and not inconsistent  with the Plan).   In making  such
        determinations, the Committee may take into account the nature of
        the  services  rendered  by  the  Optionees,  their  present  and
        potential contributions to the success of the Company and/or  one
        or more  of  its subsidiaries,  and  such other  factors  as  the
        Committee in its discretion shall deem relevant.  Subject to  the
        provisions of the  Plan, the Committee  shall also have  complete
        authority to interpret the Plan, to prescribe, amend, and rescind
        rules and regulations relating to it, to determine the terms  and
        provisions of the respective option agreements (which need not be
        identical), and  to make  all other  determinations necessary  or
        advisable for the  administration of the  Plan.  The  Committee's
        determinations on the  matters referred  to in  this paragraph  4
        shall be conclusive.

        5.   Eligibility

             An option  may be  granted  to any  person selected  by  the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting  of an  option  shall take  place at  the  time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of  an option be regarded as  taking
        place at the time when a written option agreement shall have been
        duly executed and delivered  by or on behalf  of the Company  and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things,  that it does not confer  upon
        an Optionee any right  to continue in the  employ of the  Company
        and/or one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company if  the Optionee  is a  director, or  to
        terminate the  services of  the  Optionee if  the Optionee  is  a
        consultant.

        7.   Option Period

             An option  may become  exercisable  immediately or  in  such
        installments, cumulative or noncumulative,  as the Committee  may
        determine.  

        8.   Exercise of Option

             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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  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, Subsidiary  or  the  Optionee  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.

        9.   Transferability

             Except as may be  authorized by the  Committee , in its sole
        discretion, no  Option   may be transferred other than by will or
        the laws of  descent and  distribution, and  during a  Optionee's
        lifetime an option    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). The Committee   
        may, in its  discretion, determine  the extent  to which  options
        granted to an Optionee shall be transferable, and such provisions
        permitting or acknowledging  transfer shall be  set forth in  the
        written agreement evidencing the option executed and delivered by
        or on behalf of the Company and the Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee,  in its  sole discretion,  may determine  the
        manner in which options shall vest, the rights of the Company  to
        repurchase the shares issued upon the exercise of any option  and
        the manner in which such rights  shall lapse, and the terms  upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right  to accelerate the date  of exercise of  any
        installment  or  to  accelerate   the  lapse  of  the   Company's
        repurchase rights.   All of such  terms shall be  specified in  a
        written option agreement executed and  delivered by or on  behalf
        of the Company  and the  Optionee to  whom such  option shall  be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the  event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction  in  the number  of  shares of  the  Common  Stock
        occurring after  the  date of  the  agreement and  prior  to  the
        exercise in full of  the option, the number  of shares for  which
        the option may thereafter  be exercised shall be  proportionately
        adjusted and the price to be  paid for each share subject to  the
        option shall be  proportionately adjusted.   Each such  agreement
PAGE
<PAGE>
        shall also provide that in case of any reclassification or change
        of outstanding  shares of  the Common  Stock or  in case  of  any
        consolidation or  merger  of  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
        the option,  be entitled  to  receive shares  of stock  or  other
        securities in its  place equivalent  in kind and  value to  those
        shares which  he would  have  received if  he had  exercised  the
        option  in  full  immediately  prior  to  such  reclassification,
        change,  consolidation,  merger,  sale  or  conveyance  and   had
        continued to hold the shares subject to the option (together with
        all other  shares,  stock  and securities  thereafter  issued  in
        respect thereof)  to the  time  of the  exercise of  the  option;
        provided , that if any recapitalization is to be effected  through
        an increase  in the  par value  of the  Common Stock  without  an
        increase in  the number  of authorized  shares and  such new  par
        value will  exceed the  option price  under such  agreement,  the
        Company   shall   notify   the   Optionee   of   such    proposed
        recapitalization, and  the Optionee  shall then  have the  right,
        exercisable at any time  prior to such recapitalization  becoming
        effective, to purchase all  of the shares  subject to the  option
        which  he  has  not  theretofore  purchased  (anything  in   such
        agreement to the contrary  notwithstanding), but if the  Optionee
        fails to exercise such right before such recapitalization becomes
        effective,  the  option  price  under  such  agreement  shall  be
        appropriately  adjusted.    Each  such  agreement  shall  further
        provide that upon dissolution  or liquidation of Subsidiary,  the
        option shall  terminate, but  the  Optionee (if  at the  time  an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall  have the  right, immediately  prior to  such
        dissolution or liquidation,  to exercise the  option to the  full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share  with respect to which the  option
        has  been  exercised  prior  to   the  effective  date  of   such
        adjustment; and that no fraction of a share or fractional  shares
        shall be purchasable or deliverable under such agreement, but  in
        the event  any  adjustment thereunder  of  the number  of  shares
        covered by  the  option shall  cause  such number  to  include  a
        fraction of  a share,  such  fraction shall  be adjusted  to  the
        nearest smaller whole number of shares.  In the event of  changes
        in the outstanding Common Stock by reason of any stock  dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the  Common Stock  of the nature  contemplated by  this
        paragraph 11, the number of shares of Common Stock available  for
        the purpose of the Plan as stated in paragraph 3 hereof shall  be
        correspondingly adjusted by the Committee.

        12.  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
PAGE
<PAGE>
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  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 satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising  an option, at  the request of  the
        Company, will  be  required  to give  a  representation  in  form
        satisfactory  to  counsel  for  the  Company  that  he  will  not
        transfer, sell or otherwise dispose  of the shares received  upon
        exercise of  the  option  at  any time  purchased  by  him,  upon
        exercise of any portion  of the option, in  a manner which  would
        violate  the  Securities  Act  of  1933,  as  amended,  and   the
        regulations of the Securities and Exchange Commission  thereunder
        and the Company  may, if required  or at its  discretion, make  a
        notation on any certificates issued  upon exercise of options  to
        the effect that  such certificate may  not be transferred  except
        after  receipt  by   the  Company  of   an  opinion  of   counsel
        satisfactory to  it to  the effect  that such  transfer will  not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments  of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect  to
        any shares issued upon  exercise of options  under the Plan  (the
        "withholding requirements").  The  Committee will have the  right
        to require that the Optionee or other appropriate person remit to
        the Company  an  amount  sufficient to  satisfy  the  withholding
        requirements, or  make  other arrangements  satisfactory  to  the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding  is required, the Committee  may
        permit the Optionee or  such other person to  elect at such  time
        and in such manner as the Committee 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 requirements.

        16.  Termination and Amendment of Plan

             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,
PAGE
<PAGE>
        the Board  of  Directors  may not  effect  such  modification  or
        amendment without such approval.

             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.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2008   and no options  shall be granted
        hereunder thereafter.




                                                EXHIBIT 10.49

                           THERMO ELECTRON CORPORATION

                ONIX SYSTEMS INC. NONQUALIFIED STOCK OPTION PLAN


        1.   Purpose

             This Nonqualified Stock Option Plan (the "Plan") is intended
        to encourage  ownership of  Common Stock,  $0.01 par  value  (the
        "Common  Stock"),  of  ONIX  Systems  Inc.       ("Subsidiary"),  
        subsidiary of  Thermo Electron  Corporation   (the  "Company"), by
        persons selected  by  the  Board of  Directors  (or  a  committee
        thereof) in its sole  discretion, including directors,  executive
        officers, key employees  and consultants of  the Company and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan

             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        3.   Stock Subject to Plan

             At no time shall  the number of shares  of the Common  Stock
        then outstanding  which  are  attributable  to  the  exercise  of
        options granted under  the Plan  plus the number  of shares  then
        issuable upon the exercise  of outstanding options granted  under
        the  Plan  exceed  150,000  shares, subject however, to the
        provisions of paragraph 11 of the Plan.  Shares to be issued upon
        the exercise of options granted under the Plan shall be shares of
        Subsidiary beneficially  owned by  the Company.   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.

        4.   Administration

             The  Plan  shall  be   administered  by  a  committee   (the
        "Committee") composed of the members of the Board of Directors of
        the Company,  no  member  of  which shall  act  upon  any  matter
        exclusively affecting  any option  granted or  to be  granted  to
        himself or herself under the Plan.  Subject to the provisions  of
        the Plan, the  Committee shall  have complete  authority, in  its
        discretion, to make the following determinations with respect  to
        each option to  be granted  by the Company:   (a)  the person  to
        receive the option (the "Optionee"); (b) the time of granting the
        option; (c) the number of shares subject thereto; (d) the  option
        price; (e) the option period; and (f) the terms of the option and
        form of option agreement (which need not be identical, but  which
        shall conform to the applicable terms and conditions of the  Plan
        and contain such other provisions as the Board of Directors deems
PAGE
<PAGE>
        advisable and not inconsistent  with the Plan).   In making  such
        determinations, the Committee may take into account the nature of
        the  services  rendered  by  the  Optionees,  their  present  and
        potential contributions to the success of the Company and/or  one
        or more  of  its subsidiaries,  and  such other  factors  as  the
        Committee in its discretion shall deem relevant.  Subject to  the
        provisions of the  Plan, the Committee  shall also have  complete
        authority to interpret the Plan, to prescribe, amend, and rescind
        rules and regulations relating to it, to determine the terms  and
        provisions of the respective option agreements (which need not be
        identical), and  to make  all other  determinations necessary  or
        advisable for the  administration of the  Plan.  The  Committee's
        determinations on the  matters referred  to in  this paragraph  4
        shall be conclusive.

        5.   Eligibility

             An option  may be  granted  to any  person selected  by  the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting  of an  option  shall take  place at  the  time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of  an option be regarded as  taking
        place at the time when a written option agreement shall have been
        duly executed and delivered  by or on behalf  of the Company  and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things,  that it does not confer  upon
        an Optionee any right  to continue in the  employ of the  Company
        and/or one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company if  the Optionee  is a  director, or  to
        terminate the  services of  the  Optionee if  the Optionee  is  a
        consultant.

        7.   Option Period

             An option  may become  exercisable  immediately or  in  such
        installments, cumulative or noncumulative,  as the Committee  may
        determine.  

        8.   Exercise of Option

             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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  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, Subsidiary  or  the  Optionee  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.

        9.   Transferability

             Except as may be  authorized by the  Committee , in its sole
        discretion, no  Option   may be transferred other than by will or
        the laws of  descent and  distribution, and  during a  Optionee's
        lifetime an option    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). The Committee   
        may, in its  discretion, determine  the extent  to which  options
        granted to an Optionee shall be transferable, and such provisions
        permitting or acknowledging  transfer shall be  set forth in  the
        written agreement evidencing the option executed and delivered by
        or on behalf of the Company and the Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee,  in its  sole discretion,  may determine  the
        manner in which options shall vest, the rights of the Company  to
        repurchase the shares issued upon the exercise of any option  and
        the manner in which such rights  shall lapse, and the terms  upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right  to accelerate the date  of exercise of  any
        installment  or  to  accelerate   the  lapse  of  the   Company's
        repurchase rights.   All of such  terms shall be  specified in  a
        written option agreement executed and  delivered by or on  behalf
        of the Company  and the  Optionee to  whom such  option shall  be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the  event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction  in  the number  of  shares of  the  Common  Stock
        occurring after  the  date of  the  agreement and  prior  to  the
        exercise in full of  the option, the number  of shares for  which
        the option may thereafter  be exercised shall be  proportionately
        adjusted and the price to be  paid for each share subject to  the
        option shall be  proportionately adjusted.   Each such  agreement
PAGE
<PAGE>
        shall also provide that in case of any reclassification or change
        of outstanding  shares of  the Common  Stock or  in case  of  any
        consolidation or  merger  of  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
        the option,  be entitled  to  receive shares  of stock  or  other
        securities in its  place equivalent  in kind and  value to  those
        shares which  he would  have  received if  he had  exercised  the
        option  in  full  immediately  prior  to  such  reclassification,
        change,  consolidation,  merger,  sale  or  conveyance  and   had
        continued to hold the shares subject to the option (together with
        all other  shares,  stock  and securities  thereafter  issued  in
        respect thereof)  to the  time  of the  exercise of  the  option;
        provided , that if any recapitalization is to be effected  through
        an increase  in the  par value  of the  Common Stock  without  an
        increase in  the number  of authorized  shares and  such new  par
        value will  exceed the  option price  under such  agreement,  the
        Company   shall   notify   the   Optionee   of   such    proposed
        recapitalization, and  the Optionee  shall then  have the  right,
        exercisable at any time  prior to such recapitalization  becoming
        effective, to purchase all  of the shares  subject to the  option
        which  he  has  not  theretofore  purchased  (anything  in   such
        agreement to the contrary  notwithstanding), but if the  Optionee
        fails to exercise such right before such recapitalization becomes
        effective,  the  option  price  under  such  agreement  shall  be
        appropriately  adjusted.    Each  such  agreement  shall  further
        provide that upon dissolution  or liquidation of Subsidiary,  the
        option shall  terminate, but  the  Optionee (if  at the  time  an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall  have the  right, immediately  prior to  such
        dissolution or liquidation,  to exercise the  option to the  full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share  with respect to which the  option
        has  been  exercised  prior  to   the  effective  date  of   such
        adjustment; and that no fraction of a share or fractional  shares
        shall be purchasable or deliverable under such agreement, but  in
        the event  any  adjustment thereunder  of  the number  of  shares
        covered by  the  option shall  cause  such number  to  include  a
        fraction of  a share,  such  fraction shall  be adjusted  to  the
        nearest smaller whole number of shares.  In the event of  changes
        in the outstanding Common Stock by reason of any stock  dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the  Common Stock  of the nature  contemplated by  this
        paragraph 11, the number of shares of Common Stock available  for
        the purpose of the Plan as stated in paragraph 3 hereof shall  be
        correspondingly adjusted by the Committee.

        12.  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
PAGE
<PAGE>
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  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 satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising  an option, at  the request of  the
        Company, will  be  required  to give  a  representation  in  form
        satisfactory  to  counsel  for  the  Company  that  he  will  not
        transfer, sell or otherwise dispose  of the shares received  upon
        exercise of  the  option  at  any time  purchased  by  him,  upon
        exercise of any portion  of the option, in  a manner which  would
        violate  the  Securities  Act  of  1933,  as  amended,  and   the
        regulations of the Securities and Exchange Commission  thereunder
        and the Company  may, if required  or at its  discretion, make  a
        notation on any certificates issued  upon exercise of options  to
        the effect that  such certificate may  not be transferred  except
        after  receipt  by   the  Company  of   an  opinion  of   counsel
        satisfactory to  it to  the effect  that such  transfer will  not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments  of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect  to
        any shares issued upon  exercise of options  under the Plan  (the
        "withholding requirements").  The  Committee will have the  right
        to require that the Optionee or other appropriate person remit to
        the Company  an  amount  sufficient to  satisfy  the  withholding
        requirements, or  make  other arrangements  satisfactory  to  the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding  is required, the Committee  may
        permit the Optionee or  such other person to  elect at such  time
        and in such manner as the Committee 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 requirements.

        16.  Termination and Amendment of Plan

             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,
PAGE
<PAGE>
        the Board  of  Directors  may not  effect  such  modification  or
        amendment without such approval.

             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.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2008   and no options  shall be granted
        hereunder thereafter.

                           THERMO ELECTRON CORPORATION

          THE RANDERS GROUP INCORPORATED NONQUALIFIED STOCK OPTION PLAN


        1.   Purpose

             This Nonqualified Stock Option Plan (the "Plan") is intended
        to encourage  ownership of  Common Stock,  $0.01 par  value  (the
        "Common  Stock"),   of  The   Randers   Group  Incorporated       
        ("Subsidiary"), a subsidiary of Thermo Electron Corporation  (the
        "Company"), by persons selected by  the Board of Directors (or  a
        committee thereof) in its  sole discretion, including  directors,
        executive officers, key employees and consultants of the  Company
        and its  subsidiaries, and  to provide  additional incentive  for
        them to promote the  success of the business  of the Company  and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan

             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        3.   Stock Subject to Plan

             At no time shall  the number of shares  of the Common  Stock
        then outstanding  which  are  attributable  to  the  exercise  of
        options granted under  the Plan  plus the number  of shares  then
        issuable upon the exercise  of outstanding options granted  under
        the Plan  exceed  1,500,000 shares, subject however, to the 
        provisions of paragraph 11 of the Plan.  Shares to be issued upon
        the exercise of options granted under the Plan shall be shares of
        Subsidiary beneficially  owned by  the Company.   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.

        4.   Administration

             The  Plan  shall  be   administered  by  a  committee   (the
        "Committee") composed of the members of the Board of Directors of
        the Company,  no  member  of  which shall  act  upon  any  matter
        exclusively affecting  any option  granted or  to be  granted  to
        himself or herself under the Plan.  Subject to the provisions  of
        the Plan, the  Committee shall  have complete  authority, in  its
        discretion, to make the following determinations with respect  to
        each option to  be granted  by the Company:   (a)  the person  to
        receive the option (the "Optionee"); (b) the time of granting the
        option; (c) the number of shares subject thereto; (d) the  option
        price; (e) the option period; and (f) the terms of the option and
        form of option agreement (which need not be identical, but  which
        shall conform to the applicable terms and conditions of the  Plan
        and contain such other provisions as the Board of Directors deems
PAGE
<PAGE>
        advisable and not inconsistent  with the Plan).   In making  such
        determinations, the Committee may take into account the nature of
        the  services  rendered  by  the  Optionees,  their  present  and
        potential contributions to the success of the Company and/or  one
        or more  of  its subsidiaries,  and  such other  factors  as  the
        Committee in its discretion shall deem relevant.  Subject to  the
        provisions of the  Plan, the Committee  shall also have  complete
        authority to interpret the Plan, to prescribe, amend, and rescind
        rules and regulations relating to it, to determine the terms  and
        provisions of the respective option agreements (which need not be
        identical), and  to make  all other  determinations necessary  or
        advisable for the  administration of the  Plan.  The  Committee's
        determinations on the  matters referred  to in  this paragraph  4
        shall be conclusive.

        5.   Eligibility

             An option  may be  granted  to any  person selected  by  the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting  of an  option  shall take  place at  the  time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of  an option be regarded as  taking
        place at the time when a written option agreement shall have been
        duly executed and delivered  by or on behalf  of the Company  and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things,  that it does not confer  upon
        an Optionee any right  to continue in the  employ of the  Company
        and/or one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company if  the Optionee  is a  director, or  to
        terminate the  services of  the  Optionee if  the Optionee  is  a
        consultant.

        7.   Option Period

             An option  may become  exercisable  immediately or  in  such
        installments, cumulative or noncumulative,  as the Committee  may
        determine.  

        8.   Exercise of Option

             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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  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, Subsidiary  or  the  Optionee  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.

        9.   Transferability

             Except as may be  authorized by the  Committee , in its sole
        discretion, no  Option   may be transferred other than by will or
        the laws of  descent and  distribution, and  during a  Optionee's
        lifetime an option    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). The Committee   
        may, in its  discretion, determine  the extent  to which  options
        granted to an Optionee shall be transferable, and such provisions
        permitting or acknowledging  transfer shall be  set forth in  the
        written agreement evidencing the option executed and delivered by
        or on behalf of the Company and the Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee,  in its  sole discretion,  may determine  the
        manner in which options shall vest, the rights of the Company  to
        repurchase the shares issued upon the exercise of any option  and
        the manner in which such rights  shall lapse, and the terms  upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right  to accelerate the date  of exercise of  any
        installment  or  to  accelerate   the  lapse  of  the   Company's
        repurchase rights.   All of such  terms shall be  specified in  a
        written option agreement executed and  delivered by or on  behalf
        of the Company  and the  Optionee to  whom such  option shall  be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the  event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction  in  the number  of  shares of  the  Common  Stock
        occurring after  the  date of  the  agreement and  prior  to  the
        exercise in full of  the option, the number  of shares for  which
        the option may thereafter  be exercised shall be  proportionately
        adjusted and the price to be  paid for each share subject to  the
        option shall be  proportionately adjusted.   Each such  agreement
PAGE
<PAGE>
        shall also provide that in case of any reclassification or change
        of outstanding  shares of  the Common  Stock or  in case  of  any
        consolidation or  merger  of  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
        the option,  be entitled  to  receive shares  of stock  or  other
        securities in its  place equivalent  in kind and  value to  those
        shares which  he would  have  received if  he had  exercised  the
        option  in  full  immediately  prior  to  such  reclassification,
        change,  consolidation,  merger,  sale  or  conveyance  and   had
        continued to hold the shares subject to the option (together with
        all other  shares,  stock  and securities  thereafter  issued  in
        respect thereof)  to the  time  of the  exercise of  the  option;
        provided , that if any recapitalization is to be effected  through
        an increase  in the  par value  of the  Common Stock  without  an
        increase in  the number  of authorized  shares and  such new  par
        value will  exceed the  option price  under such  agreement,  the
        Company   shall   notify   the   Optionee   of   such    proposed
        recapitalization, and  the Optionee  shall then  have the  right,
        exercisable at any time  prior to such recapitalization  becoming
        effective, to purchase all  of the shares  subject to the  option
        which  he  has  not  theretofore  purchased  (anything  in   such
        agreement to the contrary  notwithstanding), but if the  Optionee
        fails to exercise such right before such recapitalization becomes
        effective,  the  option  price  under  such  agreement  shall  be
        appropriately  adjusted.    Each  such  agreement  shall  further
        provide that upon dissolution  or liquidation of Subsidiary,  the
        option shall  terminate, but  the  Optionee (if  at the  time  an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall  have the  right, immediately  prior to  such
        dissolution or liquidation,  to exercise the  option to the  full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share  with respect to which the  option
        has  been  exercised  prior  to   the  effective  date  of   such
        adjustment; and that no fraction of a share or fractional  shares
        shall be purchasable or deliverable under such agreement, but  in
        the event  any  adjustment thereunder  of  the number  of  shares
        covered by  the  option shall  cause  such number  to  include  a
        fraction of  a share,  such  fraction shall  be adjusted  to  the
        nearest smaller whole number of shares.  In the event of  changes
        in the outstanding Common Stock by reason of any stock  dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the  Common Stock  of the nature  contemplated by  this
        paragraph 11, the number of shares of Common Stock available  for
        the purpose of the Plan as stated in paragraph 3 hereof shall  be
        correspondingly adjusted by the Committee.

        12.  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
PAGE
<PAGE>
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  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 satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising  an option, at  the request of  the
        Company, will  be  required  to give  a  representation  in  form
        satisfactory  to  counsel  for  the  Company  that  he  will  not
        transfer, sell or otherwise dispose  of the shares received  upon
        exercise of  the  option  at  any time  purchased  by  him,  upon
        exercise of any portion  of the option, in  a manner which  would
        violate  the  Securities  Act  of  1933,  as  amended,  and   the
        regulations of the Securities and Exchange Commission  thereunder
        and the Company  may, if required  or at its  discretion, make  a
        notation on any certificates issued  upon exercise of options  to
        the effect that  such certificate may  not be transferred  except
        after  receipt  by   the  Company  of   an  opinion  of   counsel
        satisfactory to  it to  the effect  that such  transfer will  not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments  of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect  to
        any shares issued upon  exercise of options  under the Plan  (the
        "withholding requirements").  The  Committee will have the  right
        to require that the Optionee or other appropriate person remit to
        the Company  an  amount  sufficient to  satisfy  the  withholding
        requirements, or  make  other arrangements  satisfactory  to  the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding  is required, the Committee  may
        permit the Optionee or  such other person to  elect at such  time
        and in such manner as the Committee 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 requirements.

        16.  Termination and Amendment of Plan

             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,
PAGE
<PAGE>
        the Board  of  Directors  may not  effect  such  modification  or
        amendment without such approval.

             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.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2008   and no options  shall be granted
        hereunder thereafter.

        4.   Administration

             The  Plan  shall  be   administered  by  a  committee   (the

        or more  of  its subsidiaries,  and  such other  factors  as  the
        Committee in its discretion shall deem relevant.  Subject to  the
        provisions of the  Plan, the Committee  shall also have  complete

        rules and regulations relating to it, to determine the terms  and
        provisions of the respective option agreements (which need not be
        identical), and  to make  all other  determinations necessary  or
        advisable for the  administration of the  Plan.  The  Committee's
        determinations on the  matters referred  to in  this paragraph  4
        shall be conclusive.

        5.   Eligibility

             An option  may be  granted  to any  person selected  by  the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting  of an  option  shall take  place at  the  time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of  an option be regarded as  taking
        place at the time when a written option agreement shall have been
        duly executed and delivered  by or on behalf  of the Company  and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things,  that it does not confer  upon
        an Optionee any right  to continue in the  employ of the  Company
        and/or one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company if  the Optionee  is a  director, or  to
        terminate the  services of  the  Optionee if  the Optionee  is  a
        consultant.

        7.   Option Period

             An option  may become  exercisable  immediately or  in  such
        installments, cumulative or noncumulative,  as the Committee  may
        determine.  

        8.   Exercise of Option

             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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  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, Subsidiary  or  the  Optionee  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.

        9.   Transferability

             Except as may be  authorized by the  Committee , in its sole
        discretion, no  Option   may be transferred other than by will or
        the laws of  descent and  distribution, and  during a  Optionee's
        lifetime an option    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). The Committee   
        may, in its  discretion, determine  the extent  to which  options
        granted to an Optionee shall be transferable, and such provisions
        permitting or acknowledging  transfer shall be  set forth in  the
        written agreement evidencing the option executed and delivered by
        or on behalf of the Company and the Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee,  in its  sole discretion,  may determine  the
        manner in which options shall vest, the rights of the Company  to
        repurchase the shares issued upon the exercise of any option  and
        the manner in which such rights  shall lapse, and the terms  upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right  to accelerate the date  of exercise of  any
        installment  or  to  accelerate   the  lapse  of  the   Company's
        repurchase rights.   All of such  terms shall be  specified in  a
        written option agreement executed and  delivered by or on  behalf
        of the Company  and the  Optionee to  whom such  option shall  be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the  event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction  in  the number  of  shares of  the  Common  Stock
        occurring after  the  date of  the  agreement and  prior  to  the
        exercise in full of  the option, the number  of shares for  which
        the option may thereafter  be exercised shall be  proportionately
        adjusted and the price to be  paid for each share subject to  the
        option shall be  proportionately adjusted.   Each such  agreement
PAGE
<PAGE>
        shall also provide that in case of any reclassification or change
        of outstanding  shares of  the Common  Stock or  in case  of  any
        consolidation or  merger  of  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
        the option,  be entitled  to  receive shares  of stock  or  other
        securities in its  place equivalent  in kind and  value to  those
        shares which  he would  have  received if  he had  exercised  the
        option  in  full  immediately  prior  to  such  reclassification,
        change,  consolidation,  merger,  sale  or  conveyance  and   had
        continued to hold the shares subject to the option (together with
        all other  shares,  stock  and securities  thereafter  issued  in
        respect thereof)  to the  time  of the  exercise of  the  option;
        provided , that if any recapitalization is to be effected  through
        an increase  in the  par value  of the  Common Stock  without  an
        increase in  the number  of authorized  shares and  such new  par
        value will  exceed the  option price  under such  agreement,  the
        Company   shall   notify   the   Optionee   of   such    proposed
        recapitalization, and  the Optionee  shall then  have the  right,
        exercisable at any time  prior to such recapitalization  becoming
        effective, to purchase all  of the shares  subject to the  option
        which  he  has  not  theretofore  purchased  (anything  in   such
        agreement to the contrary  notwithstanding), but if the  Optionee
        fails to exercise such right before such recapitalization becomes
        effective,  the  option  price  under  such  agreement  shall  be
        appropriately  adjusted.    Each  such  agreement  shall  further
        provide that upon dissolution  or liquidation of Subsidiary,  the
        option shall  terminate, but  the  Optionee (if  at the  time  an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall  have the  right, immediately  prior to  such
        dissolution or liquidation,  to exercise the  option to the  full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share  with respect to which the  option
        has  been  exercised  prior  to   the  effective  date  of   such
        adjustment; and that no fraction of a share or fractional  shares
        shall be purchasable or deliverable under such agreement, but  in
        the event  any  adjustment thereunder  of  the number  of  shares
        covered by  the  option shall  cause  such number  to  include  a
        fraction of  a share,  such  fraction shall  be adjusted  to  the
        nearest smaller whole number of shares.  In the event of  changes
        in the outstanding Common Stock by reason of any stock  dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the  Common Stock  of the nature  contemplated by  this
        paragraph 11, the number of shares of Common Stock available  for
        the purpose of the Plan as stated in paragraph 3 hereof shall  be
        correspondingly adjusted by the Committee.

        12.  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
PAGE
<PAGE>
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  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 satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising  an option, at  the request of  the
        Company, will  be  required  to give  a  representation  in  form
        satisfactory  to  counsel  for  the  Company  that  he  will  not
        transfer, sell or otherwise dispose  of the shares received  upon
        exercise of  the  option  at  any time  purchased  by  him,  upon
        exercise of any portion  of the option, in  a manner which  would
        violate  the  Securities  Act  of  1933,  as  amended,  and   the
        regulations of the Securities and Exchange Commission  thereunder
        and the Company  may, if required  or at its  discretion, make  a
        notation on any certificates issued  upon exercise of options  to
        the effect that  such certificate may  not be transferred  except
        after  receipt  by   the  Company  of   an  opinion  of   counsel
        satisfactory to  it to  the effect  that such  transfer will  not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments  of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect  to
        any shares issued upon  exercise of options  under the Plan  (the
        "withholding requirements").  The  Committee will have the  right
        to require that the Optionee or other appropriate person remit to
        the Company  an  amount  sufficient to  satisfy  the  withholding
        requirements, or  make  other arrangements  satisfactory  to  the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding  is required, the Committee  may
        permit the Optionee or  such other person to  elect at such  time
        and in such manner as the Committee 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 requirements.

        16.  Termination and Amendment of Plan

             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,
PAGE
<PAGE>
        the Board  of  Directors  may not  effect  such  modification  or
        amendment without such approval.

             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.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2008   and no options  shall be granted
        hereunder thereafter.




                                                   EXHIBIT 10.52

                           THERMO ELECTRON CORPORATION

            THERMO TRILOGY CORPORATION NONQUALIFIED STOCK OPTION PLAN


        1.   Purpose

             This Nonqualified Stock Option Plan (the "Plan") is intended
        to encourage  ownership of  Common Stock,  $0.01 par  value  (the
        "Common Stock"), of Thermo Trilogy   Corporation    ("Subsidiary"),
        a subsidiary of Thermo  Electron Corporation  (the "Company"), by
        persons selected  by  the  Board of  Directors  (or  a  committee
        thereof) in its sole  discretion, including directors,  executive
        officers, key employees  and consultants of  the Company and  its
        subsidiaries, and  to provide  additional incentive  for them  to
        promote  the  success  of  the   business  of  the  Company   and
        Subsidiary.   The Plan  is intended  to be  a nonstatutory  stock
        option plan.

        2.   Effective Date of the Plan

             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        3.   Stock Subject to Plan

             At no time shall  the number of shares  of the Common  Stock
        then outstanding  which  are  attributable  to  the  exercise  of
        options granted under  the Plan  plus the number  of shares  then
        issuable upon the exercise  of outstanding options granted  under
        the  Plan  exceed  150,000  shares,  subject however, to the
        provisions of paragraph 11 of the Plan.  Shares to be issued upon
        the exercise of options granted under the Plan shall be shares of
        Subsidiary beneficially  owned by  the Company.   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.

        4.   Administration

             The  Plan  shall  be   administered  by  a  committee   (the
        "Committee") composed of the members of the Board of Directors of
        the Company,  no  member  of  which shall  act  upon  any  matter
        exclusively affecting  any option  granted or  to be  granted  to
        himself or herself under the Plan.  Subject to the provisions  of
        the Plan, the  Committee shall  have complete  authority, in  its
        discretion, to make the following determinations with respect  to
        each option to  be granted  by the Company:   (a)  the person  to
        receive the option (the "Optionee"); (b) the time of granting the
        option; (c) the number of shares subject thereto; (d) the  option
        price; (e) the option period; and (f) the terms of the option and
        form of option agreement (which need not be identical, but  which
        shall conform to the applicable terms and conditions of the  Plan
        and contain such other provisions as the Board of Directors deems
PAGE
<PAGE>
        advisable and not inconsistent  with the Plan).   In making  such
        determinations, the Committee may take into account the nature of
        the  services  rendered  by  the  Optionees,  their  present  and
        potential contributions to the success of the Company and/or  one
        or more  of  its subsidiaries,  and  such other  factors  as  the
        Committee in its discretion shall deem relevant.  Subject to  the
        provisions of the  Plan, the Committee  shall also have  complete
        authority to interpret the Plan, to prescribe, amend, and rescind
        rules and regulations relating to it, to determine the terms  and
        provisions of the respective option agreements (which need not be
        identical), and  to make  all other  determinations necessary  or
        advisable for the  administration of the  Plan.  The  Committee's
        determinations on the  matters referred  to in  this paragraph  4
        shall be conclusive.

        5.   Eligibility

             An option  may be  granted  to any  person selected  by  the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting  of an  option  shall take  place at  the  time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of  an option be regarded as  taking
        place at the time when a written option agreement shall have been
        duly executed and delivered  by or on behalf  of the Company  and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things,  that it does not confer  upon
        an Optionee any right  to continue in the  employ of the  Company
        and/or one  or more  of  its subsidiaries  or  to continue  as  a
        director or  consultant of  the  Company, and  that it  does  not
        interfere in any way  with the right of  the Company or any  such
        subsidiary to terminate  the employment  of the  Optionee at  any
        time if the Optionee is an employee, to remove the Optionee as  a
        director of the  Company if  the Optionee  is a  director, or  to
        terminate the  services of  the  Optionee if  the Optionee  is  a
        consultant.

        7.   Option Period

             An option  may become  exercisable  immediately or  in  such
        installments, cumulative or noncumulative,  as the Committee  may
        determine.  

        8.   Exercise of Option

             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 Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  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, Subsidiary  or  the  Optionee  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.

        9.   Transferability

             Except as may be  authorized by the  Committee , in its sole
        discretion, no  Option   may be transferred other than by will or
        the laws of  descent and  distribution, and  during a  Optionee's
        lifetime an option    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). The Committee   
        may, in its  discretion, determine  the extent  to which  options
        granted to an Optionee shall be transferable, and such provisions
        permitting or acknowledging  transfer shall be  set forth in  the
        written agreement evidencing the option executed and delivered by
        or on behalf of the Company and the Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee,  in its  sole discretion,  may determine  the
        manner in which options shall vest, the rights of the Company  to
        repurchase the shares issued upon the exercise of any option  and
        the manner in which such rights  shall lapse, and the terms  upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right  to accelerate the date  of exercise of  any
        installment  or  to  accelerate   the  lapse  of  the   Company's
        repurchase rights.   All of such  terms shall be  specified in  a
        written option agreement executed and  delivered by or on  behalf
        of the Company  and the  Optionee to  whom such  option shall  be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the  event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction  in  the number  of  shares of  the  Common  Stock
        occurring after  the  date of  the  agreement and  prior  to  the
        exercise in full of  the option, the number  of shares for  which
        the option may thereafter  be exercised shall be  proportionately
        adjusted and the price to be  paid for each share subject to  the
        option shall be  proportionately adjusted.   Each such  agreement
PAGE
<PAGE>
        shall also provide that in case of any reclassification or change
        of outstanding  shares of  the Common  Stock or  in case  of  any
        consolidation or  merger  of  Subsidiary  with  or  into  another
        company or in case of any  sale or conveyance to another  company
        or  entity  of  the  property   of  Subsidiary  as  a  whole   or
        substantially as a  whole, the Optionee  shall, upon exercise  of
        the option,  be entitled  to  receive shares  of stock  or  other
        securities in its  place equivalent  in kind and  value to  those
        shares which  he would  have  received if  he had  exercised  the
        option  in  full  immediately  prior  to  such  reclassification,
        change,  consolidation,  merger,  sale  or  conveyance  and   had
        continued to hold the shares subject to the option (together with
        all other  shares,  stock  and securities  thereafter  issued  in
        respect thereof)  to the  time  of the  exercise of  the  option;
        provided , that if any recapitalization is to be effected  through
        an increase  in the  par value  of the  Common Stock  without  an
        increase in  the number  of authorized  shares and  such new  par
        value will  exceed the  option price  under such  agreement,  the
        Company   shall   notify   the   Optionee   of   such    proposed
        recapitalization, and  the Optionee  shall then  have the  right,
        exercisable at any time  prior to such recapitalization  becoming
        effective, to purchase all  of the shares  subject to the  option
        which  he  has  not  theretofore  purchased  (anything  in   such
        agreement to the contrary  notwithstanding), but if the  Optionee
        fails to exercise such right before such recapitalization becomes
        effective,  the  option  price  under  such  agreement  shall  be
        appropriately  adjusted.    Each  such  agreement  shall  further
        provide that upon dissolution  or liquidation of Subsidiary,  the
        option shall  terminate, but  the  Optionee (if  at the  time  an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall  have the  right, immediately  prior to  such
        dissolution or liquidation,  to exercise the  option to the  full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share  with respect to which the  option
        has  been  exercised  prior  to   the  effective  date  of   such
        adjustment; and that no fraction of a share or fractional  shares
        shall be purchasable or deliverable under such agreement, but  in
        the event  any  adjustment thereunder  of  the number  of  shares
        covered by  the  option shall  cause  such number  to  include  a
        fraction of  a share,  such  fraction shall  be adjusted  to  the
        nearest smaller whole number of shares.  In the event of  changes
        in the outstanding Common Stock by reason of any stock  dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the  Common Stock  of the nature  contemplated by  this
        paragraph 11, the number of shares of Common Stock available  for
        the purpose of the Plan as stated in paragraph 3 hereof shall  be
        correspondingly adjusted by the Committee.

        12.  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
PAGE
<PAGE>
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  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 satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising  an option, at  the request of  the
        Company, will  be  required  to give  a  representation  in  form
        satisfactory  to  counsel  for  the  Company  that  he  will  not
        transfer, sell or otherwise dispose  of the shares received  upon
        exercise of  the  option  at  any time  purchased  by  him,  upon
        exercise of any portion  of the option, in  a manner which  would
        violate  the  Securities  Act  of  1933,  as  amended,  and   the
        regulations of the Securities and Exchange Commission  thereunder
        and the Company  may, if required  or at its  discretion, make  a
        notation on any certificates issued  upon exercise of options  to
        the effect that  such certificate may  not be transferred  except
        after  receipt  by   the  Company  of   an  opinion  of   counsel
        satisfactory to  it to  the effect  that such  transfer will  not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments  of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect  to
        any shares issued upon  exercise of options  under the Plan  (the
        "withholding requirements").  The  Committee will have the  right
        to require that the Optionee or other appropriate person remit to
        the Company  an  amount  sufficient to  satisfy  the  withholding
        requirements, or  make  other arrangements  satisfactory  to  the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding  is required, the Committee  may
        permit the Optionee or  such other person to  elect at such  time
        and in such manner as the Committee 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 requirements.

        16.  Termination and Amendment of Plan

             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,
PAGE
<PAGE>
        the Board  of  Directors  may not  effect  such  modification  or
        amendment without such approval.

             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.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2008   and no options  shall be granted
        hereunder thereafter.

    Fiscal Year
        The Company has adopted a fiscal year ending the Saturday nearest
    December 31. References to 1997, 1996, and 1995 are for the fiscal years
    ended January 3, 1998, December 28, 1996, and December 30, 1995,
    respectively. Fiscal year 1997 included 53 weeks; 1996 and 1995 each

    1.  Nature of Operations and Significant Accounting Policies (continued)

    accompanying balance sheet consists primarily of unearned revenue on
    service contracts. Substantially all of the deferred revenue in the
    accompanying 1997 balance sheet will be recognized within one year.
    Revenues and profits on substantially all contracts are recognized using
    the percentage-of-completion method. Revenues recorded under the
    percentage-of-completion method were $440.4 million in 1997, $421.1
    million in 1996, and $472.0 million in 1995. 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 that are billed but
    not paid under retainage provisions.

    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.
        If gains have been recognized on issuances of a subsidiary's stock
    and shares of the subsidiary are subsequently repurchased by the
    subsidiary, by the subsidiary's parent, or by the Company, 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. Such transactions are
    reflected as equity transactions, and the net effect of these
    transactions is reflected in the accompanying statement of shareholders'
    investment as the effect of majority-owned subsidiaries' equity
    transactions.

    Stock-based Compensation Plans
        The Company applies Accounting Principles Board Opinion (APB) No. 25,
    "Accounting for Stock Issued to Employees" and related interpretations in
    accounting for its stock-based compensation plans (Note 4). Accordingly,
    no accounting recognition is given to stock options granted at fair
    market value until they are exercised. Upon exercise, net proceeds,
    including tax benefits realized, are credited to equity.

    Income Taxes
        In accordance with Statement of Financial Accounting Standards (SFAS)
    No. 109, "Accounting for Income Taxes," the Company recognizes deferred
    income taxes 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.

    Earnings per Share
        During the fourth quarter of 1997, the Company adopted SFAS No. 128,
    "Earnings per Share" (Note 15). As a result, all previously reported
    earnings per share have been restated; however, basic earnings per share
    equals the Company's previously reported primary earnings per share for
    1996 and 1995. Basic earnings per share have been computed by dividing
    net income by the weighted average number of shares outstanding during
    the year. Diluted earnings per share have been computed assuming the
    conversion of convertible obligations and the elimination of the related
    interest expense, and the exercise of stock options, as well as their
    related income tax effects. 

    Stock Split
        All share and per share information was restated in 1996 to reflect a
    three-for-two stock split, effected in the form of a 50% stock dividend,
    that was distributed in June 1996.

    Cash and Cash Equivalents
        Cash equivalents consists principally of corporate notes, commercial
    paper, U.S. government-agency securities, money market funds, and other
    marketable securities purchased with an original maturity of three months
    or less. These investments are carried at cost, which approximates market
    value.

    Inventories
        Inventories are stated at the lower of cost (on a first-in, first-out
    or weighted average basis) or market value and include materials, labor,
    and manufacturing overhead. 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
    improvements, 5 to 40 years; alternative-energy facilities, 5 to 25
    years; machinery and equipment, 2 to 20 years; and leasehold
    improvements, the shorter of the term of the lease or the life of the
    asset.

    Other Assets
        Other assets in the accompanying balance sheet includes intangible
    assets, notes receivable, deferred debt expense, prepaid pension costs,
    and other assets. Intangible assets include the costs of acquired
    trademarks, patents, product technology, and other specifically
    identifiable intangible assets and are being amortized using the
    straight-line method over their estimated useful lives, which range from
    3 to 20 years. Intangible assets were $50.5 million and $39.9 million,
    net of accumulated amortization of $45.7 million and $38.0 million, at
    year-end 1997 and 1996, respectively.

    Cost in Excess of Net Assets of Acquired Companies
        The excess of cost over the fair value of net assets of acquired
    companies is amortized using the straight-line method principally over 40
    years. Accumulated amortization was $134.7 million and $96.4 million at
    year-end 1997 and 1996, respectively. The Company assesses the future
    useful life of this asset whenever events or changes in circumstances
    indicate that the current useful life has diminished. The Company
    considers the future undiscounted cash flows of the acquired companies in
    assessing the recoverability of this asset. If impairment has occurred,
    any excess of carrying value over fair value is recorded as a loss.

    Common Stock of Subsidiaries Subject to Redemption
        In March 1995, ThermoLyte sold 1,845,000 units, each unit consisting
    of one share of ThermoLyte common stock and one redemption right, at
    $10.00 per unit, for net proceeds of $17.3 million. Holders of the common
    stock issued in the offering will have the option to require ThermoLyte
    to redeem any or all of their shares at $10.00 per share in December 1998
    or 1999. ThermoLyte common stock subject to redemption of $18.1 million
    is included in other accrued expenses in the accompanying 1997 balance
    sheet since it is redeemable in December 1998. The redemption value is
    $18.5 million.

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Significant Accounting Policies (continued)

        In September 1996, Thermo Fibergen sold 4,715,000 units, each unit
    consisting of one share of Thermo Fibergen common stock and one
    redemption right, at $12.75 per unit, for net proceeds of $55.8 million.
    The common stock and redemption rights began trading separately on
    December 13, 1996. Holders of a redemption right have the option to
    require Thermo Fibergen to redeem one share of Thermo Fibergen common
    stock at $12.75 per share in September 2000 or 2001. The redemption
    rights carry terms that generally provide for their expiration if the
    closing price of Thermo Fibergen's common stock exceeds $19 1/8 for 20 of
    any 30 consecutive trading days prior to September 2001.
        In April 1997, ThermoLase completed an exchange offer whereby its
    shareholders had the opportunity to exchange one share of existing
    ThermoLase common stock and $3.00 (in cash or ThermoLase common stock)
    for a new unit consisting of one share of ThermoLase common stock and one
    redemption right. The redemption right entitles the holder to sell the
    related share of common stock to ThermoLase for $20.25 during the period
    from April 3, 2001, through April 30, 2001. The redemption right will
    expire if the closing price of ThermoLase common stock is at least $26.00
    for 20 of any 30 consecutive trading days. In connection with this offer,
    ThermoLase issued in April 1997, 2,000,000 units in exchange for
    2,261,706 shares of its common stock and $0.5 million in cash, net of
    expenses. As a result of these transactions, $40.5 million was
    reclassified from "Shareholders' investment" and "Minority interest" to
    "Common stock of subsidiaries subject to redemption," based on the
    issuance of the 2,000,000 redemption rights, each carrying a maximum
    liability of $20.25.
        The difference between the redemption value and the original carrying
    amount of ThermoLyte and Thermo Fibergen common stock subject to
    redemption is accreted over the period through the first redemption
    period. Accretion is charged to minority interest expense in the
    accompanying statement of income. All redemption rights are guaranteed on
    a subordinated basis by the Company.

    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.

    Forward Contracts and Interest Rate Swap Agreements
        The Company uses short-term forward foreign exchange contracts to
    manage certain exposures to foreign currencies. The Company enters into
    forward foreign exchange contracts to hedge firm purchase and sale
    commitments denominated in currencies other than its subsidiaries' local
    currencies. These contracts principally hedge transactions denominated in

                                       14PAGE

    1.  Nature of Operations and Significant Accounting Policies (continued)

    U.S. dollars, British pounds sterling, French francs, and Japanese yen.
    The purpose of the Company's foreign currency hedging activities is to
    protect the Company's local currency cash flows related to these
    commitments from fluctuations in foreign exchange rates. Gains and losses
    arising from forward foreign exchange contracts are recognized as offsets
    to gains and losses resulting from the transactions being hedged.
        Thermo Ecotek has interest rate swap agreements that convert its
    variable rate obligations to fixed rate obligations (Note 5). Interest
    rate swap agreements are accounted for under the accrual method. Amounts
    to be received from or paid to the counterparties of the agreements are
    accrued during the period to which the amounts relate and are reflected
    as interest expense. The related amounts payable to the counterparties
    are included in other accrued expenses in the accompanying balance sheet.
    The fair value of the swap agreements is not recognized in the
    accompanying financial statements since the agreements are accounted for
    as hedges.
        The Company does not enter into speculative foreign currency or
    interest swap agreements.

    Use of Estimates
        The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities,
    disclosure of contingent assets and liabilities at the date of the
    financial statements, and the reported amounts of revenues and expenses
    during the reporting period. Actual results could differ from those
    estimates.

    Presentation
        Certain amounts in 1996 and 1995 have been reclassified to conform to
    the presentation in the 1997 financial statements.

    2.  Available-for-sale Investments

        In accordance with SFAS No. 115, "Accounting for Certain Investments
    in Debt and Equity Securities," the Company's debt and marketable equity
    securities are considered available-for-sale investments in the
    accompanying balance sheet and 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 on available-for-sale investments."

        Short- and long-term available-for-sale investments in the
    accompanying 1997 balance sheet include equity securities of $50.4
    million and debt securities of $803.3 million with contractual maturities
    of one year or less and $138.7 million 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 either the Company, the issuer, or both 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 and losses
    recorded in the accompanying statement of income. The net gain on sale of
    investments resulted from gross realized gains of $5.2 million, $11.2
    million, and $9.8 million and gross realized losses of $0.1 million, $1.4
    million, and $0.5 million in 1997, 1996, and 1995, respectively, relating
    to the sale of available-for-sale investments.

    3.  Acquisitions

        In March 1997, Thermo Instrument acquired 95% of Life Sciences
    International PLC, a London Stock Exchange-listed company. Subsequently,
    Thermo Instrument acquired the remaining shares of Life Sciences'

    capital stock. The aggregate purchase price for Life Sciences was $442.8
    million, net of $55.8 million of cash acquired. The purchase price
    includes the repayment of $105.0 million of Life Sciences' bank debt.
    Life Sciences manufactures laboratory science equipment, appliances,
    instruments, consumables, and reagents for the research, clinical, and
    industrial markets.
        In 1997, in addition to the acquisition of Life Sciences, the Company
    and its majority-owned subsidiaries made several other acquisitions for
    an aggregate of $406.3 million in cash, net of cash acquired, the
    issuance of subsidiary common stock and stock options valued at $4.5
    million, and $5.1 million to be paid in the first quarter of 1998,
    subject to certain post-closing adjustments. The Company does not expect
    that aggregate post-closing adjustments, if any, will be material.
        In June 1996, the Company acquired SensorMedics Corporation in
    exchange for 1,243,518 shares of the Company's common stock, including
    156,590 shares reserved for issuance upon exercise of assumed stock
    options and warrants. SensorMedics manufactures systems for pulmonary
    function diagnosis, respiratory-gas analyzers, physiological testing
    equipment, and automated sleep-analysis systems. The acquisition has been
    accounted for under the pooling-of-interests method.
        Historical financial information presented for 1995 has been restated
    to include the acquisition of SensorMedics. Revenues and net income
    (loss) for 1995, as previously reported by the separate entities prior to

         In March 1996, Thermo Instrument completed the acquisition of a
    substantial portion of the businesses constituting the Scientific
    Instruments Division of Fisons plc (Fisons businesses), a wholly owned
    subsidiary of Rhone-Poulenc Rorer Inc. (RPR), for approximately $181.2
    million in cash, net of $7.7 million of cash acquired, and the assumption
    of approximately $47.2 million of indebtedness. In December 1997, Thermo
    Instrument and RPR negotiated a post-closing adjustment under the terms
    of the purchase agreement for the Fisons acquisition pertaining to
    determination of the net assets of the Fisons businesses at the date of

    acquisition. This negotiation resulted in a refund to Thermo Instrument
    of $36.1 million, plus $3.8 million of interest from the date of
    acquisition. Thermo Instrument has recorded $33.1 million of the refund
    as a reduction in cost in excess of net assets of acquired companies. The
    remaining $3.0 million represented payment for uncollected accounts
    receivable acquired by the Company that were guaranteed by RPR.
        In 1996, in addition to the acquisitions of SensorMedics and the
    Fisons businesses, the Company and its majority-owned subsidiaries made
    several other acquisitions for an aggregate of $185.1 million in cash,
    net of cash acquired, the issuance of common stock of the Company and its
    majority-owned subsidiaries valued at $2.4 million, and the issuance of
    $26.6 million in debt.
        In March 1995, the Company acquired Coleman Research Corporation in
    exchange for 6,003,336 shares of the Company's common stock, including
    304,292 shares reserved for issuance upon exercise of assumed stock
    options. This business was renamed Thermo Coleman Corporation. Thermo
    Coleman provides systems integration, systems engineering, analytical
    services, technology support, information technology services and
    products, and advanced-technology research and development to government
    and commercial customers. The acquisition has been accounted for under
    the pooling-of-interests method.
        In 1995, in addition to the acquisition of Thermo Coleman, the
    Company and its majority-owned subsidiaries made several other
    acquisitions for an aggregate of $330.7 million in cash, net of cash
    acquired, the issuance of common stock and stock options of the Company's
    majority-owned subsidiaries valued at $19.0 million, and the issuance of
    $22.3 million in debt.
        These acquisitions, except for SensorMedics and Thermo Coleman, have
    been accounted for using the purchase method of accounting, and the
    acquired companies' results 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 $1,239.8 million, which is being amortized
    principally 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 1997, is subject to
    adjustment upon finalization of the purchase price allocation. The
    Company has gathered no information that indicates the final purchase
    price allocations will differ materially from the preliminary estimates.
    Pro forma data is not presented since the acquisitions were not material
    to the Company's results of operations.
        In connection with the acquisition of the Fisons businesses, Thermo
    Instrument had undertaken a restructuring of the acquired businesses
    during 1996. In accordance with the requirements of Emerging Issues Task
    Force Pronouncement (EITF) 95-3, Thermo Instrument finalized its
    restructuring plans in the first quarter of 1997. The restructuring plans
    include reductions in staffing levels, abandonment of excess facilities,
    and other costs associated with exiting certain activities of the
    acquired businesses. As part of the cost of the acquisition, Thermo
    Instrument established reserves totaling $46.2 million for estimated

    severance, excess facilities, and other exit costs associated with the
    acquisition, $14.3 million and $19.0 million of which was expended during
    1997 and 1996, respectively, primarily for severance and
    abandoned-facility payments. At January 3, 1998, the remaining reserve
    for restructuring these businesses was $11.1 million, including the
    impact of currency translation, and primarily represents ongoing
    severance and abandoned-facility payments.

    4.  Employee Benefit Plans

    Stock-based Compensation Plans

    Stock Option Plans
    ------------------
        The Company has stock-based compensation plans for its key employees,
    directors, and others, which permit the award of stock-based incentives
    in the stock of the Company and its majority-owned subsidiaries. The
    Company has a nonqualified stock option plan, adopted in 1974, and an
    incentive stock option plan, adopted in 1981, which permit the award of
    stock options to key employees. The incentive stock option plan expired
    in 1991, and no grants were made after that date. An equity incentive
    plan, adopted in 1989, 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.
    The option recipients and the terms of options granted under these plans
    are determined by the Board Committee. Generally, options outstanding
    under these plans 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 may lapse over periods
    ranging from one to ten years, depending on the term of the option, which
    may range from three to twelve years. In addition, under certain options,
    shares acquired upon exercise are restricted from resale until retirement
    or other events. Nonqualified options are generally granted at fair
    market value, although the Board Committee has discretion to grant
    options at a price at or above 85% of the fair market value on the date
    of grant. Incentive stock options must be granted at not less than the
    fair market value of the Company's stock on the date of grant. Generally,
    stock options have been granted at fair market value. The Company also
    has a directors' stock option plan, adopted in 1993, that provides for
    the annual grant of stock options of the Company and its majority-owned
    subsidiaries to outside 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 in
    stock-based compensation plans of the Company's majority-owned
    subsidiaries.

       The information disclosed above for options outstanding at January 3,
    1998, does not differ materially for options exercisable.

    Employee Stock Purchase Plan
    ----------------------------
       Substantially all 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 common stock can be
    purchased at the end of a 12-month period at 95% of the fair market value
    at the beginning of the period, and the shares purchased are subject to a
    six-month resale restriction. Prior to November 1, 1995, shares of the
    Company's common stock could be purchased at 85% of the fair market value
    at the beginning of the period, and the shares purchased were subject to
    a one-year resale restriction. Shares are purchased through payroll
    deductions of up to 10% of each participating employee's gross wages.
    Participants of employee stock purchase programs sponsored by the
    Company's majority-owned public subsidiaries may also elect to purchase
    shares of the common stock of the subsidiary by which they are employed
    under the same general terms described above. During 1997, 1996, and
    1995, the Company issued 243,444 shares, 285,448 shares, and 330,444
    shares, respectively, of its common stock under this plan.

    Employee Stock Ownership Plan
    -----------------------------
       The Company's Employees Stock Ownership Plan (ESOP) was split into
    two plans effective December 31, 1994: ESOP I and ESOP II. The ESOP I
    covers eligible full-time U.S. employees of the Company's corporate
    office and its wholly owned subsidiaries. The ESOP II, terminated
    effective December 31, 1994, covered employees of certain of the
    Company's majority-owned subsidiaries. The Company loaned funds to the
    ESOP to purchase shares of common stock of the Company and its
    majority-owned subsidiaries. The shares purchased by the ESOP were

    4.  Employee Benefit Plans (continued)

    recorded as deferred compensation in the accompanying balance sheet. The
    loan to the ESOP II was repaid in full in 1996 and all expense related to
    the plans had been recognized. The loan repayment was recorded as a
    reduction in deferred compensation in the accompanying balance sheet.
    Shares are allocated to the plan participants based on employee
    compensation. For these plans, the Company charged to expense $0.2
    million and $0.3 million in 1996 and 1995, respectively.

    Pro Forma Stock-based Compensation Expense
        In October 1995, the Financial Accounting Standards Board issued SFAS
    No. 123, "Accounting for Stock-based Compensation," which sets forth a
    fair-value based method of recognizing stock-based compensation expense.
    As permitted by SFAS No. 123, the Company has elected to continue to
    apply APB No. 25 to account for its stock-based compensation plans. Had
    compensation cost for awards in 1997, 1996, and 1995 under the Company's
    stock-based compensation plans been determined based on the fair value at
    the grant dates consistent with the method set forth under SFAS No. 123,
    the effect on the Company's net income and earnings per share would have
    been as follows:

    (In thousands except per share amounts)    1997       1996        1995
    -----------------------------------------------------------------------
    Net income:
      As reported                          $239,328   $190,816    $139,582
      Pro forma                             224,337    181,880     137,587
    Basic earnings per share:
      As reported                              1.57       1.35        1.10
      Pro forma                                1.47       1.29        1.09
    Diluted earnings per share:
      As reported                              1.41       1.17         .95
      Pro forma                                1.32       1.12         .93

        Because the method prescribed by SFAS No. 123 has not been applied to
    options granted prior to January 1, 1995, the resulting pro forma
    compensation expense may not be representative of the amount to be
    expected in future years. Pro forma compensation expense for options
    granted is reflected over the vesting period; therefore, future pro forma
    compensation expense may be greater as additional options are granted.
        The weighted average fair value per share of options granted was
    $15.14, $13.03, and $9.39 in 1997, 1996, and 1995, respectively. The fair
    value of each option grant was estimated on the grant date using the
    Black-Scholes option-pricing model with the following weighted-average
    assumptions:

                                               1997        1996        1995

    4.  Employee Benefit Plans (continued)

        The Black-Scholes option-pricing model was developed for use in
    estimating the fair value of traded options which have no vesting
    restrictions and are fully transferable. In addition, option-pricing
    models require the input of highly subjective assumptions including
    expected stock price volatility. Because the Company's employee stock
    options have characteristics significantly different from those of traded
    options, and because changes in the subjective input assumptions can
    materially affect the fair value estimate, in management's opinion, the
    existing models do not necessarily provide a reliable single measure of
    the fair value of its employee stock options.

    401(k) Savings Plan
        The Company's 401(k) savings plan covers the majority of the
    Company's eligible full-time U.S. employees. Contributions to the plan
    are made by both the employee and the Company. Company contributions are
    based on the level of employee contributions. For this plan, the Company
    contributed and charged to expense $13.9 million, $10.1 million, and $7.6
    million in 1997, 1996, and 1995, respectively.

    Other Retirement Plans
        Certain of the Company's subsidiaries offer retirement plans,
    separate from the Company's 401(k) savings plan. These retirement plans
    cover approximately 20% of the Company's U.S. employees. The majority of
    these subsidiaries offer 401(k) savings plans; however, one subsidiary
    offers a money purchase plan and two subsidiaries offer profit-sharing
    plans. Company contributions to the 401(k) savings plans are based on the
    level of employee contributions. Company contributions to the money
    purchase plan and profit-sharing plans are based on formulas determined
    by the Company. For these plans, the Company contributed and charged to

        The debentures that are convertible into subsidiary common stock have
    been issued by the respective subsidiaries and are guaranteed by the
    Company, on a subordinated basis in most cases.
        In the event of a change in control of the Company (as defined in the
    related fiscal agency agreement) that has not been approved by the
    continuing members of the Company's Board of Directors, each holder of
    the 4 1/4% convertible debentures issued by the Company will have the
    right to require the Company to buy all or part of the holder's
    debentures, at par value plus accrued interest, within 50 calendar days
    after the date of expiration of a specified approval period. In addition,
    certain of the obligations convertible into subsidiary common stock
    become exchangeable for common stock of the Company at an exchange price
    equal to 50% of the average price of the Company's common stock for the
    30 trading days preceding the change in control.
        Nonrecourse tax-exempt obligations represent obligations issued by
    the California Pollution Control Financing Authority, the proceeds of
    which were used to finance two alternative-energy facilities (Delano I
    and Delano II) located in Delano, California. The obligations are
    credit-enhanced by a letter of credit issued by a bank group. The
    obligations are payable only by a subsidiary of Thermo Ecotek and are not
    guaranteed by the Company, except under limited circumstances. As
    required by the financing bank group, Thermo Ecotek entered into interest
    rate swap agreements that effectively convert these obligations from
    floating rates to the fixed rates described above. These swaps have terms
    expiring in 2000, commensurate with the final maturity of the debt.
    During 1997 and 1996, the average variable rate received under the
    interest rate swap agreements was 3.7% and 3.5%, respectively. The
    notional amount of the swap agreements was $61.3 million and $95.7

    million at year-end 1997 and 1996, respectively. The interest rate swap
    agreements are with a different counterparty than the holders of the
    underlying debt. The Company believes, however, that the credit risks
    associated with these swaps are minimal because the agreements are with a
    large, reputable bank.
        The annual requirements for long-term obligations are as follows:

    long-term obligations.
        Notes payable and current maturities of long-term obligations in the
    accompanying balance sheet includes $105.7 million and $112.9 million in
    1997 and 1996, respectively, of short-term bank borrowings and borrowings
    under lines of credit of certain of the Company's subsidiaries. The
    weighted average interest rate for these borrowings was 5.7% and 5.4% at
    year-end 1997 and 1996. Unused lines of credit were $205 million as of
    year-end 1997.

    6.  Commitments and Contingencies

    Operating Leases
        The Company leases portions of its office and operating facilities
    under various operating lease arrangements. The accompanying statement of
    income includes expenses from operating leases of $73.6 million, $62.6
    million, and $48.8 million in 1997, 1996, and 1995, respectively. Future
    minimum payments due under noncancelable operating leases at January 3,
    1998, are $71.0 million in 1998; $60.7 million in 1999; $52.2 million in
    2000; $45.8 million in 2001; $42.6 million in 2002; and $165.5 million in
    2003 and thereafter. Total future minimum lease payments are $437.8
    million.

    Litigation and Related Contingencies
        ThermoTrex is a defendant in a lawsuit brought by Fischer Imaging
    Corporation, which alleges that the prone breast-biopsy systems of the
    Lorad division of ThermoTrex's Trex Medical subsidiary infringe a Fischer
    patent on a precision mammographic needle-biopsy system. Lorad's
    cumulative revenues from this product totaled approximately $118.6
    million through January 3, 1998.

    6.  Commitments and Contingencies (continued)

        Five former employees of Thermo Instrument's Epsilon Industrial, Inc.
    (Epsilon) subsidiary have commenced an arbitration proceeding naming as
    joint defendants Epsilon, Thermo Instrument, and certain affiliates of
    Thermo Instrument, including the Company, alleging that these entities
    breached the terms of certain agreements entered into with such employees
    at the time that a predecessor of Epsilon acquired the assets and
    business of a company formerly owned by such employees. The former
    employees are claiming actual damages of between $27 million and $46
    million, punitive damages of twice the actual damages, attorneys' fees
    and expenses, and pre-judgment and post-judgment interest, resulting from
    the alleged failure of Thermo Instrument and such affiliates, to, among
    other things, use their best efforts to develop and promote certain
    products acquired at that time. The arbitration proceeding, which is
    binding and nonappealable, is expected to conclude in the second quarter
    of 1998.
        Thermo Coleman has been named as a defendant in a lawsuit initiated
    by certain former employees. This suit was filed under the "qui tam"
    provisions of the Federal False Claims Act (the Act), which permit an
    individual to bring suit in the name of the United States and, if the
    United States obtains a judgment against the defendant, to share in any
    recovery. The suit alleges, among other things, that Thermo Coleman
    violated the Act as a result of its performance of certain
    support-service functions under a subcontract from a third party, which,
    in turn, contracted directly with the U.S. government. The complaint
    seeks an order requiring Thermo Coleman to cease and desist from such
    allegedly improper practices, the award of treble damages in an
    unspecified amount, plus other penalties. The amount of billings under
    the contract activities in question were approximately $7.6 million.
    Under the law, the U.S. government will investigate the allegations set
    forth in the complaint, and then will determine whether it wishes to
    intervene and take over the lawsuit. The Company has been advised that
    the U.S. government has not completed its investigation and that no
    decision has been made on whether the U.S. government will intervene in
    the lawsuit.
        ThermoQuest's Finnigan subsidiary has filed complaints against
    Bruker-Franzen Analytik GmbH and its U.S. affiliate, and Hewlett-Packard
    Company, for alleged violation of two U.S. patents owned by Finnigan
    pertaining to methods used in ion-trap mass spectrometers. One of
    Finnigan's complaints was filed in United States District Court and the
    other was filed with the United States International Trade Commission
    (ITC). In February 1998, an administrative law judge at the ITC issued an
    initial determination to the effect that, although one of Finnigan's
    patents was infringed, the patents were invalid for purposes of this
    case. The ITC's jurisdiction on this matter is limited to the issue of
    whether or not the defendants' products that use the patented methods can
    be imported into the U.S. The judge's initial determination will be
    considered by the full commission during the second quarter of 1998.
    Bruker has presented counterclaims alleging that the Finnigan patents are
    invalid and unenforceable and are not infringed by the mass spectrometers
    co-marketed by Bruker. They also allege that Finnigan has violated

    antitrust laws by attempting to maintain a monopoly position and restrain
    trade through enforcement of allegedly fraudulently obtained patents.
    Bruker has asked for judgment consistent with its counterclaims, and for
    three times the antitrust damages (including attorney's fees) it has
    sustained.
        The Company intends to vigorously defend these matters. In the
    opinion of management, the ultimate liability for all such matters will
    not be material to the Company's financial position, but an unfavorable
    outcome in one or more of the matters described above could materially
    affect the results of operations or cash flows for a particular quarter
    or annual period.

    7.  Common Stock

        At January 3, 1998, the Company had reserved 31,354,154 unissued
    shares of its common stock for possible issuance under stock-based
    compensation plans, for possible conversion of the Company's convertible
    debentures, and for possible exchange of certain subsidiaries'
    convertible obligations into common stock of the Company. Certain of the
    subsidiaries' obligations are exchangeable into common stock of the
    Company in the event of a change in control (as defined in the related
    fiscal agency agreement) that has not been approved by the continuing
    members of the Company's Board of Directors (Note 5). The exchange price
    would be equal to 50% of the average price of the Company's common stock
    for the 30 trading days preceding the change in control.
        In January 1996, the Company redeemed the share purchase rights
    outstanding under its previously existing shareholder rights plan for
    $.02 per right, or $.006 per share of the Company's common stock
    outstanding. Simultaneously with this redemption, the Company distributed
    rights under a new shareholder rights plan adopted by the Company's Board
    of Directors to holders of outstanding shares of the Company's common
    stock. Each right entitles the holder to purchase one ten-thousandth of a
    share of Series B Junior Participating Preferred Stock, $100 par value,
    at a purchase price of $250 per share, subject to adjustment. The rights
    will not be exercisable until the earlier of (i) 10 days following a
    public announcement that a person or group of affiliated or associated
    persons (an Acquiring Person) has acquired, or obtained the right to
    acquire, beneficial ownership of 15% or more of the outstanding shares of
    common stock (the Stock Acquisition Date), or (ii) 10 business days
    following the commencement of a tender offer or exchange offer for 15% or
    more of the outstanding shares of common stock.
        In the event that a person becomes the beneficial owner of 15% or
    more of the outstanding shares of common stock, except pursuant to an
    offer for all outstanding shares of common stock approved by the outside
    Directors, each holder of a right (except for the Acquiring Person) will
    thereafter have the right to receive, upon exercise, that number of
    shares of common stock that equals the exercise price of the right
    divided by one half of the current market price of the common stock. In
    the event that, at any time after any person has become an Acquiring
    Person, (i) the Company is acquired in a merger or other business

    7.  Common Stock (continued)

    combination transaction in which the Company is not the surviving
    corporation or its common stock is changed or exchanged (other than a
    merger that follows an offer approved by the outside Directors), or
    (ii) 50% or more of the Company's assets or earning power is sold or
    transferred, each holder of a right (except for the Acquiring Person)
    shall thereafter have the right to receive, upon exercise, the number of
    shares of common stock of the acquiring company that equals the exercise
    price of the right divided by one half of the current market price of
    such common stock.
        At any time until 10 days following the Stock Acquisition Date, the
    Company may redeem the rights in whole, but not in part, at a price of
    $.01 per right (payable in cash or stock). The rights expire on January
    29, 2006, unless earlier redeemed or exchanged.

    8.  Income Taxes (continued)

        The Company and its majority-owned subsidiaries receive a tax
    deduction upon exercise of nonqualified stock options by employees for
    the difference between the exercise price and the market price of the
    underlying common stock on the date of exercise. The provision for income
    taxes that is currently payable does not reflect $15.4 million, $24.5
    million, and $20.5 million of such benefits of the Company and its
    majority-owned subsidiaries that have been allocated to capital in excess
    of par value, directly or through the effect of majority-owned
    subsidiaries' equity transactions, in 1997, 1996, and 1995, respectively.
    In addition, the provision for income taxes that is currently payable
    does not reflect $1.9 million, $6.5 million, and $3.0 million of tax
    benefits used to reduce cost in excess of net assets of acquired
    companies in 1997, 1996, and 1995, respectively. The deferred provision
    for income taxes does not reflect $5.9 million of tax benefits used to
    reduce cost in excess of net assets of acquired companies in 1995.
        The provision for income taxes in the accompanying statement of
    income differs from the provision calculated by applying the statutory
    federal income tax rate of 35% to income before income taxes and minority
    interest due to the following:

        The valuation allowance relates to the uncertainty surrounding the
    realization of tax loss carryforwards and the realization of tax benefits
    attributable to accrued acquisition expenses and certain other tax assets
    of the Company and certain subsidiaries. Of the year-end 1997 valuation
    allowance, $49 million 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. During 1997, the valuation allowance decreased
    primarily due to the decrease in tax loss carryforwards.
        At year-end 1997, the Company had foreign and federal net operating
    loss carryforwards of $133 million and $37 million, respectively. Use of
    the carryforwards is limited based on the future income of certain
    subsidiaries. The federal net operating loss carryforwards expire in the
    years 1998 through 2012. Of the foreign net operating loss carryforwards,
    $10 million expire in the years 1998 through 2004, and the remainder do
    not expire.
        The Company has not recognized a deferred tax liability for the
    difference between the book basis and tax basis of its investment in the
    common stock of its domestic subsidiaries (such difference relates
    primarily to unremitted earnings and gains on issuance of stock by
    subsidiaries) because the Company does not expect this basis difference
    to become subject to tax at the parent level. The Company believes it can
    implement certain tax strategies to recover its investment in its
    domestic subsidiaries tax-free.

    8.  Income Taxes (continued)

        A provision has not been made for U.S. or additional foreign taxes on
    $216 million of undistributed earnings of foreign subsidiaries that could
    be subject to taxation if remitted to the U.S. because the Company
    currently plans to keep these amounts permanently reinvested overseas.

    9.  Transactions in Stock of Subsidiaries

    11. Restructuring and Other Nonrecurring Costs, Net
        Restructuring and other nonrecurring costs, net, in 1997 includes
    $7.8 million to write down certain capital equipment and intangible
    assets, including cost in excess of net assets of acquired companies, in
    response to a severe downturn in Thermo Remediation's soil-remediation
    business that resulted in closure of two soil-remediation sites during
    1997 and reduced cash flows at certain other sites, such that analysis
    indicated that the investment in these assets would not be recovered.
    During 1997, the Company settled two legal cases in which it was a
    defendant concerning development of a proposed waste-to-energy facility
    and development and construction of an alternative-energy facility. These
    matters were settled for amounts less than the damages that had been
    sought by the plaintiffs and less than the amounts that had been reserved
    by the Company. As a result, the Company reversed $9.7 million of
    reserves previously established for these matters, which is included as a
    reduction of restructuring and other nonrecurring costs in 1997. In
    addition, the 1997 amount includes $3.4 million of restructuring and
    other nonrecurring costs, primarily severance, at two majority-owned
    subsidiaries and at the Company's wholly owned businesses and $1.4
    million at ThermoTrex for the write-off of acquired technology relating
    to an acquisition. This amount represents the portion of the purchase
    price allocated to technology in development at the acquired business.
    The 1997 amount also includes a gain of $2.2 million from the sale of a
    business by ThermoSpectra and $0.6 million of other nonrecurring costs.
        The 1996 amount includes a write-off of $12.7 million of cost in
    excess of net assets of acquired company and certain other intangible
    assets at Thermedics' Corpak subsidiary, as a result of Thermedics no
    longer intending to further invest in this business and reduced cash
    flows, such that analysis indicated that the investment in these assets
    would not be recovered. The 1996 amount also includes $11.4 million of
    costs recorded by SensorMedics primarily as a result of its merger with
    the Company, including employee compensation that became payable as a
    result of the merger with the Company, certain investment banking fees
    and other related transaction costs, the settlement of a pre-acquisition
    legal dispute, and severance costs for terminated employees. In addition,

   11. Restructuring and Other Nonrecurring Costs, Net (continued)

   $4.4 million was recorded by the Company's wholly owned Peter Brotherhood
   Ltd. subsidiary primarily for the write-off of a nontrade receivable and
   severance costs, and $3.5 million and $4.9 million were recorded by Thermo
   Instrument and Thermo Cardiosystems, respectively, for the write-off of
   acquired technology relating to an acquisition at each subsidiary. These
   amounts represent the portion of the purchase price allocated to technology
   in development at the acquired businesses.
       The 1995 amount includes $11.5 million to write off the Company's net
   investment in a waste-recycling facility in San Diego County, California,
   that was subsequently sold in 1996. The 1995 amount also includes $5.0
   million to write off the cost in excess of net assets of acquired companies
   at Thermo TerraTech's thermal-processing equipment business due to this
   asset no longer being recoverable based on discontinuing investment in this
   business and reduced cash flows, such that analysis indicated that the
   investment in these assets would not be recovered. In addition, $2.5
   million was recorded to write off the cost in excess of net assets of
   acquired companies at the Company's wholly owned Napco Inc. subsidiary and
   $2.9 million was recorded for other nonrecurring costs at other business
   units.

    13. Fair Value of Financial Instruments

        The Company's financial instruments consist mainly of cash and cash
    equivalents, available-for-sale investments, accounts receivable, notes
    payable and current maturities of long-term obligations, accounts
    payable, long-term obligations, forward foreign exchange contracts, and
    interest rate swaps. The carrying amount of these financial instruments,
    with the exception of available-for-sale investments, long-term
    obligations, forward foreign exchange contracts, and interest rate swaps,
    approximates fair value due to their short-term nature.
        Available-for-sale investments are carried at fair value in the
    accompanying balance sheet. The fair values were determined based on
    quoted market prices. See Note 2 for fair value information pertaining to
    these financial instruments.
        The carrying amount and fair value of the Company's long-term
    obligations and off-balance-sheet financial instruments are as follows:

                                    1997                      1996

                          $1,742,907   $1,940,468   $1,550,342  $1,787,961
                          ==========   ==========   ==========  ==========

    Off-balance-sheet
      financial instruments:
        Forward foreign
          exchange contracts
          receivable                   $   (1,731)              $   (1,370)
        Interest rate
          swaps payable                $    1,324               $    1,643

        The fair value of long-term obligations was determined based on
    quoted market prices and on borrowing rates available to the Company at
    the respective year ends. The fair value of convertible obligations
    exceeds the carrying amount primarily due to the market price of the
    Company's or subsidiaries' common stock exceeding the conversion price of
    the convertible obligations.
        The Company had forward foreign exchange contracts of $46.6 million
    and $19.7 million outstanding at year-end 1997 and 1996, respectively.
    Additionally, the notional amount of the Company's interest rate swap
    agreements was $61.3 million and $95.7 million at year-end 1997 and 1996,
    respectively (Note 5). The fair value of such contracts and swap
    agreements is the estimated amount that the Company would pay or receive
    upon termination of the contract, taking into account the change in
    foreign exchange rates on forward foreign exchange contracts, and market
    interest rates and the creditworthiness of the counterparties on interest
    rate swap agreements.

        The computation of diluted earnings per share for each period
    excludes the effect of assuming the exercise of certain outstanding stock
    options because the effect would be antidilutive. As of January 3, 1998,
    there were 1,058,100 of such options outstanding, with exercise prices
    ranging from $39.43 to $43.46 per share.

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors
    of Thermo Electron Corporation:

        We have audited the accompanying consolidated balance sheet of Thermo
    Electron Corporation (a Delaware corporation) and subsidiaries as of
    January 3, 1998, and December 28, 1996, and the related consolidated
    statements of income, shareholders' investment, and cash flows for each
    of the three years in the period ended January 3, 1998. These
    consolidated financial statements are the responsibility of the Company's
    management. Our responsibility is to express an opinion on these
    consolidated financial statements based on our audits.
        We conducted our audits in accordance with generally accepted
    auditing standards. Those standards require that we plan and perform the
    audit to obtain reasonable assurance about whether the financial
    statements are free of material misstatement. An audit includes
    examining, on a test basis, evidence supporting the amounts and
    disclosures in the financial statements. An audit also includes assessing
    the accounting principles used and significant estimates made by
    management, as well as evaluating the overall financial statement
    presentation. We believe that our audits provide a reasonable basis for
    our opinion.
        In our opinion, the consolidated financial statements referred to
    above present fairly, in all material respects, the financial position of
    Thermo Electron Corporation and subsidiaries as of January 3, 1998, and
    December 28, 1996, and the results of their operations and their cash
    flows for each of the three years in the period ended January 3, 1998, in
    conformity with generally accepted accounting principles.

                  Financial Condition and Results of Operations

        Forward-looking statements, within the meaning of Section 21E of the
    Securities Exchange Act of 1934, are made throughout this Management's
    Discussion and Analysis of Financial Condition and Results of Operations.
    For this purpose, any statements contained herein that are not statements
    of historical fact may be deemed to be forward-looking statements.
    Without limiting the foregoing, the words "believes," "anticipates,"
    "plans," "expects," "seeks," "estimates," and similar expressions are
    intended to identify forward-looking statements. There are a number of
    important factors that could cause the results of the Company to differ
    materially from those indicated by such forward-looking statements,
    including those detailed immediately after this Management's Discussion
    and Analysis of Financial Condition and Results of Operations under the
    heading "Forward-looking Statements."

    Overview

        The Company develops and manufactures a broad range of products that
    are sold worldwide. The Company expands the product lines and services it
    offers by developing and commercializing its own core technologies and by
    making strategic acquisitions of complementary businesses. The majority
    of the Company's businesses fall into six broad markets: instruments,
    alternative-energy, paper recycling, biomedical, industrial outsourcing,
    and advanced technologies.
        An important component of the Company's strategy is to establish
    leading positions in its markets through the application of proprietary
    technology, whether developed internally or acquired. A key contribution
    to the growth of the Company's segment income (as defined in the results
    of operations below), particularly over the last several years, has been
    the ability to identify attractive acquisition opportunities, complete
    those acquisitions, and derive a growing income contribution from the
    newly acquired businesses as they are integrated into the Company's
    business segments and their profitability improves.
        The Company seeks to minimize its dependence on any specific product
    or market by expanding and diversifying its portfolio of businesses and
    technologies. Similarly, the Company's goal is to maintain a balance in
    its businesses between those affected by various regulatory cycles and
    those more dependent on the general level of economic activity. Although
    the Company is diversified in terms of technology, product offerings, and
    geographic markets served, the future financial performance of the
    Company as a whole will be largely affected by the strength of worldwide
    economies and the continued adoption and diligent enforcement of health,
    safety, and environmental regulations and standards, among other factors.
        The Company believes that maintaining an entrepreneurial atmosphere
    is essential to its continued growth and development. In order to
    preserve this atmosphere, the Company has adopted a strategy of spinning
    out certain of its businesses into separate subsidiaries and having these
    subsidiaries sell a minority interest to outside investors. The Company
    believes that this strategy provides additional motivation and incentives
    for the management of the subsidiaries through the establishment of
    subsidiary-level stock option programs, as well as capital to support the
    subsidiaries' growth. As a result of the sale of stock by subsidiaries,

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

    Overview (continued)

    the issuance of stock by subsidiaries upon conversion of convertible
    debentures, and similar transactions, the Company records gains that
    represent the increase in the Company's net investment in the
    subsidiaries and are classified as "Gain on issuance of stock by
    subsidiaries" in the accompanying statement of income. These gains have
    represented a substantial portion of the net income reported by the
    Company in certain periods. The size and timing of these transactions are
    dependent on market and other conditions that are beyond the Company's
    control. Accordingly, there can be no assurance that the Company will be
    able to generate gains from such transactions in the future.
        Further, in October 1995, the Financial Accounting Standards Board
    (FASB) issued an exposure draft of a Proposed Statement of Financial
    Accounting Standards, "Consolidated Financial Statements: Policy and
    Procedures" (the Proposed Statement). The Proposed Statement would
    establish new rules for how consolidated financial statements should be
    prepared. If the Proposed Statement is adopted, there would be
    significant changes in the way the Company records certain transactions
    of its controlled subsidiaries. Among those changes, any sale of the
    stock of a subsidiary that does not result in a loss of control would be
    accounted for as a transaction in equity of the consolidated entity with
    no gain or loss being recorded. The exposure draft addresses the
    consolidation issues in two parts: consolidation procedures, which
    includes proposed rule changes affecting the Company's ability to
    recognize gains on issuances of subsidiary stock, and consolidation
    policy, which does not address accounting for such gains. During 1997,
    the FASB decided to focus its efforts on the consolidation policy part of
    the exposure draft and to consider resuming discussion on consolidation
    procedures after completion of the efforts on consolidation policy. The
    timing and content of any final statement are uncertain.

    Results of Operations

    1997 Compared With 1996
        Sales in 1997 were $3,558.3 million, an increase of $625.8 million,
    or 21%, over 1996. Segment income, excluding restructuring and other
    nonrecurring costs, net, of $1.3 million in 1997 and $37.6 million in
    1996, described below, increased 40% to $438.3 million in 1997 from
    $312.9 million in 1996. (Segment income is income before corporate
    general and administrative expenses, other income and expense, minority
    interest expense, and income taxes.) Operating income, which includes
    restructuring and other nonrecurring costs, net, increased 65% to $405.8
    million in 1997 from $246.5 million in 1996.

    Instruments
    -----------
        Sales from the Instruments segment were $1,592.3 million in 1997, an
    increase of $383.0 million, or 32%, over 1996. Sales increased primarily
    due to acquisitions made by Thermo Instrument, which added $407 million
    of sales in 1997. The unfavorable effects of currency translation due to
    the strengthening of the U.S. dollar relative to foreign currencies in

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

    1997 Compared With 1996 (continued)
    countries in which Thermo Instrument operates decreased revenues by $46.8
    million in 1997. In addition, revenues increased in 1997 due to higher
    sales at ThermoQuest's existing mass spectrometry business, partly as a
    result of the continued success of a new product introduced in the first
    quarter of 1996, and due to increased sales from Metrika Systems,
    primarily as a result of increased sales in international markets at its
    on-line raw-materials analyzer business. Revenues also increased at ONIX
    Systems, primarily due to increased sales of industry-specific
    instruments to the production segment of the oil and gas industry.
    Revenues from Thermo Optek's existing businesses decreased slightly due
    to the inclusion in 1996 of several large nonrecurring sales to the
    Chinese and Japanese governments, a decrease in demand for elemental
    products in Japan, and the elimination of certain unprofitable acquired
    product lines, offset substantially by greater demand at one of its
    business units. 
        Segment income margin (segment income margin is segment income as a
    percentage of sales), excluding nonrecurring items, net, of $1.3 million
    of income in 1997 and $3.5 million of costs in 1996, improved to 14.7% in
    1997 from 11.8% in 1996. The improvement was primarily due to operating
    margin improvement at certain of the Fisons businesses acquired in 1996
    and increased sales of ThermoQuest's higher-margin mass spectrometry
    products. This increase was offset in part by the inclusion of
    lower-margin revenues at certain acquired businesses, including Life
    Sciences, which recorded an adjustment to expense of $3.6 million
    relating to the sale of inventories revalued at the date of acquisition
    and, to a lesser extent, a decrease in segment income margin at
    ThermoSpectra, primarily as a result of a one-time inventory write-off
    and a change in sales mix at one of its business units. The 1996 period
    included a charge of $2.0 million relating to the sale of inventories
    revalued at the date of the acquisition of the Fisons businesses.
    Nonrecurring income of $1.3 million in 1997 represents a $2.2 million
    gain on the sale of a business by ThermoSpectra, offset in part by $0.9
    million of severance costs for employees terminated during 1997 at one of
    ThermoSpectra's business units. During 1996, the Company recorded
    nonrecurring costs of $3.5 million, which represented the write-off of
    acquired technology relating to the acquisition of the Fisons businesses
    (Note 11).

    Alternative-energy Systems
    --------------------------
        Sales from the Alternative-energy Systems segment were $384.9 million
    in 1997, compared with $339.8 million in 1996. Within this segment,
    revenues from Thermo Ecotek increased to $189.5 million in 1997 from
    $154.3 million in 1996. Revenues from Thermo Ecotek's Thermo Trilogy
    biopesticide subsidiary increased by $18.7 million to $21.4 million,
    primarily due to the inclusion of revenues from two acquired businesses.
    Thermo Ecotek's revenues in 1997 include $8.2 million for a contractual
    settlement with a utility, pursuant to which Thermo Ecotek surrendered
    its rights to a power sales agreement relating to a cogeneration facility
    it had planned to develop and construct on Staten Island, New York. The
    settlement, reached in 1993, called for Thermo Ecotek to refund $8.2

                  Financial Condition and Results of Operations

    1997 Compared With 1996 (continued)
    million to the utility should Thermo Ecotek construct and commence
    operations of a plant on Staten Island prior to 2000. Thermo Ecotek had
    deferred recognition of the refundable portion of the settlement pending
    a decision concerning development of the plant. During 1997, Thermo
    Ecotek determined that, due to economic conditions in the domestic energy
    market, it would not proceed with development of a facility on Staten
    Island. In addition, higher contractual energy rates at all of Thermo
    Ecotek's facilities, except the Hemphill plant in New Hampshire,
    contributed to higher revenues in 1997. Pursuant to Thermo Ecotek's
    utility contracts for its four plants in California, there will be no
    further contractual energy rate increases beginning in 1998. Revenues in
    1996 from the Company's wholly owned waste-recycling facility in southern
    California, which was sold in July 1996, were $9.2 million. Sales at
    Peter Brotherhood declined to $39.6 million in 1997 from $54.4 million in
    1996, primarily due to the disposal of certain business units, which
    resulted in a $14.2 million decrease in revenues. The business units were
    sold for a nominal loss. Sales from Thermo Power increased to $155.8
    million in 1997 from $122.1 million in 1996, primarily due to $38.8
    million of sales from Peek plc, acquired in November 1997, as well as
    higher engine sales due to a $3.6 million nonrecurring order from one
    customer, offset in part by lower demand for Thermo Power's remaining
    product lines.
        Segment income, excluding nonrecurring items, net, of $8.3 million of
    income in 1997 and $4.4 million of costs in 1996, was $60.2 million in
    1997, compared with $42.5 million in 1996. Thermo Ecotek's segment income
    was $50.4 million in 1997, compared with $39.3 million in 1996. The
    increase primarily resulted from $8.2 million of segment income from the
    contractual settlement with a utility concerning the cancellation of a
    power sales agreement and, to a lesser extent, higher contractual energy
    rates. These increases were offset in part by a decrease in Thermo
    Ecotek's segment income of $4.6 million in 1997 as a result of the
    funding of certain reserves required in connection with a nonrecourse
    lease agreement for its Woodland, California plant. The Woodland plant's
    results were approximately breakeven in 1997 and are expected to remain
    so for the foreseeable future. Segment income in 1996 from the Company's
    waste-recycling facility, which was sold in July 1996, was $4.6 million.
    Results from this facility, net of related interest expense (not included
    in segment income), were approximately breakeven in 1996. During 1997,
    the Company settled two legal cases in which it was a defendant,
    concerning development of a proposed waste-to-energy facility and
    development and construction of an alternative-energy facility. These
    matters were settled for amounts less than the damages that had been
    sought by the plaintiffs and less than the amounts that had been reserved
    by the Company. As a result, in 1997, the Company reversed $9.7 million
    of reserves previously established for these matters, which is included
    in restructuring and other nonrecurring costs, net (Note 11). Segment
    income at Thermo Power improved to $7.5 million from $1.1 million in
    1996, primarily due to contributions from Peek and, to a lesser extent,
    improved segment income at its engines and industrial refrigeration
    businesses, due to increased engine revenues, lower warranty costs in

    both businesses, as well as lower overhead as a result of consolidating
    two engine manufacturing facilities. Excluding restructuring and other
    nonrecurring costs of $1.4 million in 1997 and $4.4 million in 1996,
    Peter Brotherhood was profitable in 1997, compared with a segment loss of
    $2.5 million in 1996. The restructuring and other nonrecurring costs in
    1997 related primarily to severance for employees terminated in 1997 and
    in 1996 related primarily to the write-off of a nontrade receivable and
    severance costs.
        Two of Thermo Ecotek's plants are located in New Hampshire and sell
    power to Public Service Company of New Hampshire (PSNH). In January 1997,
    PSNH's parent company, Northeast Utilities, disclosed in a filing with
    the Securities and Exchange Commission that if a proposed deregulation
    plan for the New Hampshire electric utility industry were adopted, PSNH
    could default on certain financial obligations and seek bankruptcy
    protection. In February 1997, the New Hampshire Public Utilities
    Commission (NHPUC) voted to adopt a deregulation plan, and in March 1997,
    PSNH filed suit to block the plan. In March 1997, the federal district
    court issued a temporary restraining order that prohibits the NHPUC from
    implementing the deregulation plan as it affects PSNH, pending a
    determination by the court on whether PSNH's claim could be heard by the
    court. In April 1997, the court ruled that it could now hear the case and
    ordered that the restraining order would continue indefinitely pending
    the outcome of the suit. In addition, in March 1997, Thermo Ecotek, along
    with a group of other biomass power producers, filed a motion with the
    NHPUC seeking clarification of the NHPUC's proposed deregulation plan
    regarding several issues, including purchase requirements and payment of
    current rate order prices with respect to Thermo Ecotek's energy output.
    An unfavorable resolution of this matter, including the bankruptcy of
    PSNH, could have a material adverse effect on Thermo Ecotek's results of
    operations and financial position.
        Thermo Ecotek has continued to address issues concerning operations
    at its Gillette, Wyoming, coal-beneficiation facility. Thermo Ecotek has
    conducted extensive testing and operated the facility, producing
    commercially salable product. For tax purposes, the facility must be
    "placed in service" by June 30, 1998, to qualify for certain tax credits
    on its output. Although the facility has operated and produced
    commercially salable product, Thermo Ecotek has encountered certain
    difficulties in achieving optimal and sustained operation. Thermo Ecotek
    has addressed and resolved certain problems previously encountered,
    including a fire at the facility and certain construction problems
    relating to the flow of materials within the facility and the design and
    operation of certain pressure-release equipment. Currently, Thermo Ecotek
    is experiencing certain operational problems relating to tar residue
    build-up within the system during production. Thermo Ecotek is actively
    exploring solutions to this problem. Because the technology being
    developed at the facility is new and untested, no assurance can be given
    that other difficulties will not arise or that Thermo Ecotek will be able
    to correct these problems and achieve optimal and sustained performance.

    1997 Compared With 1996 (continued)
    Paper Recycling
    ---------------
        Sales in the Paper Recycling segment were $278.9 million in 1997,
    compared with $286.3 million in 1996. A wholly owned subsidiary of the
    Company recorded $58.0 million of revenues from a contract to design and
    construct an office wastepaper de-inking facility in 1996. This contract
    was substantially completed in the second quarter of 1996. Sales from
    Thermo Fibertek increased 25% to $239.6 million from $192.2 million in
    1996, primarily due to revenues of $52.7 million from acquired
    businesses, principally Thermo Black Clawson, which was acquired in May
    1997. Increases in revenues from Thermo Fibertek's accessories,
    water-management, and other businesses were substantially offset by a
    $11.3 million decrease in revenues at its recycling business due to a
    continuing decrease in demand resulting from a severe drop in de-inked
    pulp prices in 1996. In addition, the unfavorable effects of currency
    translation reduced Thermo Fibertek's revenues by $6.3 million in 1997.
    Sales from Thermo TerraTech's thermal-processing equipment business were
    $25.3 million in 1997, compared with $25.5 million in 1996. In October
    1997, this business was sold for a nominal loss. Sales of automated
    electroplating equipment by Napco increased $3.4 million to $14.0
    million, primarily due to higher demand.
        Segment income margin, excluding restructuring and other nonrecurring
    costs of $1.1 million in 1997, was 11.5% in 1997, compared with 12.6% in
    1996. This decline primarily resulted from lower sales at Thermo
    Fibertek's recycling business and lower-margin revenues from Thermo Black
    Clawson. In addition, the Company recorded a segment loss in 1997 on the
    contract to design and construct the office wastepaper de-inking facility
    due to a reserve established in 1997 for disputed contractual items
    relating to this facility. Thermo Fibertek recorded restructuring and
    other nonrecurring costs of $1.1 million in 1997 relating to the
    consolidation of the operations of two of its subsidiaries into the
    operations of Thermo Black Clawson (Note 11).

    Biomedical Products
    -------------------
        Sales from the Biomedical Products segment were $590.2 million in
    1997, an increase of $134.3 million, or 29%, over 1996. Sales increased
    due to the inclusion of $62.7 million in sales from acquired businesses,
    increased demand at Trex Medical and Bird Medical Technologies, Inc., and
    growth at ThermoLase's hair-removal business due to the opening of new
    spas and higher revenues from physician and international licensing
    arrangements. Rather than continuing to open additional domestic spas,
    ThermoLase intends to concentrate its resources on attempting both to
    increase the capacity utilization of its existing U.S. spas and to expand
    its physicians' licensing program and international licensing
    arrangements. These increases in revenues were offset in part by a $4.7
    million decline in sales of Thermo Cardiosystems' left ventricular-assist
    systems (LVAS), which Thermo Cardiosystems believes resulted from delayed
    orders as customers await approval from the U.S. Food and Drug
    Administration of its advanced electric LVAS. Although Thermo
    Cardiosystems believes that such approval may be received during the

    first six months of 1998, there can be no assurance that approval will
    occur within the expected time period, or at all.
        Segment income, excluding restructuring and other nonrecurring costs
    of $0.5 million in 1997 and $29.7 million in 1996, increased to $53.2
    million in 1997 from $46.1 million in 1996. This increase resulted
    substantially from improvements at existing businesses, primarily at Bird
    Medical, SensorMedics Corporation, and Trex Medical's existing businesses
    and, to a lesser extent, the inclusion of segment income from acquired
    businesses. This increase in segment income was offset in part by an
    increase in segment loss at ThermoLase to $18.4 million in 1997 from $7.6
    million in 1996, due to the early operations of its Spa Thira
    hair-removal business, which has been operating below maximum capacity as
    it seeks to develop its client base and refine its process and operating
    procedures, and by pre-opening costs incurred in connection with new spa
    openings. ThermoLase believes that improvements in the efficacy and
    duration of its SoftLight(SM) hair-removal process are critical elements
    in its ability to improve the profitability of its spas. In 1998, the
    effect of operating each spa below maximum capacity, as ThermoLase
    develops its client base and expands its product lines, will continue to
    have a negative effect on ThermoLase's segment income. Thermo
    Cardiosystems' profitability declined by $4.7 million primarily due to a
    decrease in LVAS revenues. Restructuring and other nonrecurring costs of
    $0.5 million in 1997 represent costs to close certain foreign sales
    offices at certain of the Company's wholly owned businesses.
    Restructuring and other nonrecurring costs of $29.7 million in 1996
    included a write-off of $12.7 million of cost in excess of net assets of
    acquired company and certain other intangible assets at Thermedics'
    Corpak subsidiary, $11.4 million of costs incurred by SensorMedics
    primarily as a result of its merger with the Company, $4.9 million for
    Thermo Cardiosystem's write-off of acquired technology relating to a 1996
    acquisition, and $0.7 million of other costs (Note 11).

    Industrial Outsourcing
    ----------------------
        Sales in the Industrial Outsourcing segment were $305.5 million in
    1997, an increase of $31.6 million, or 12%, over 1996. Revenues from
    Thermo TerraTech's remediation and recycling services increased to $136.5
    million in 1997 from $121.2 million in 1996, primarily due to the
    inclusion of $22.9 million of sales from acquired businesses, offset in
    part by a $6.4 million decrease in revenues at one of Thermo
    Remediation's business units resulting from a decline in the number of
    contracts in process. In addition, revenues from Thermo Remediation's
    soil-remediation services decreased 18% to $18.5 million, resulting from
    lower volumes of soil processed due to overcapacity in the industry and,
    to a lesser extent, competitive pricing pressures early in the year.
    Revenues from consulting and design services increased $3.6 million due
    to the inclusion of $12.8 million from acquired businesses, offset in
    part by a decrease in revenues due to the completion of two large
    contracts. Sales of metallurgical services increased to $54.2 million in
    1997 from $45.7 million in 1996, due to increased demand for existing
    services and the inclusion of $3.3 million of sales from an acquired
    business.

    Thermo Electron Corporation                     1997 Financial Statements

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

    1997 Compared With 1996 (continued)
        Segment income, excluding restructuring and other nonrecurring costs
    of $7.9 million in 1997 and $0.1 million in 1996, was $21.7 million in
    1997, compared with $17.8 million in 1996. Segment income improved in
    1997 due to the effect in 1996 of costs incurred at Thermo TerraTech to
    reduce redundancies at regional laboratories, and by costs incurred at
    Thermo EuroTech in 1996 relating primarily to the settlement of several
    contract disputes, as well as the impact of severe winter weather in
    early 1996, which affected all phases of Thermo EuroTech's business. The
    effect of these improvements was offset in part by a decline in segment
    income from soil-remediation services due to lower sales as discussed
    above and lower segment income from consulting and design services due to
    the completion of two large contracts. Restructuring and other
    nonrecurring costs in 1997 included $7.8 million to write down certain
    capital equipment and intangible assets, including cost in excess of net
    assets of acquired companies, in response to a severe downturn in Thermo
    Remediation's soil-remediation business. This resulted in the closure of
    two soil-remediation sites during 1997 and reduced cash flows at certain
    other sites, such that analysis indicated that the investment in these
    assets would not be recovered (Note 11).

    Advanced Technologies
    ---------------------
        Sales from the Advanced Technologies segment were $415.0 million in
    1997, compared with $375.5 million in 1996. Sales at Thermo Coleman were
    $156.2 million in 1997, compared with $144.2 million in 1996. This
    increase resulted primarily from its Thermo Information Solutions
    subsidiary's contract to supply kiosk units and, to a lesser extent,
    higher integrated document management revenues and sales of $3.3 million
    from acquired businesses. These increases in revenues were offset in part
    by a decrease in revenues from government contracts. Sales of kiosk units
    increased to $16.5 million in 1997 from $1.4 million in 1996. Thermo
    Information Solutions intends to exit this business in 1998 due to
    inherently low margins, lower than expected orders from its sole
    customer, and the absence of other orders. Thermo Coleman experienced a
    decline in backlog totaling $19.4 million in 1997. Thermo Coleman's
    backlog at any certain date may not be indicative of future demand for
    its products or services. Sales at Thermo Sentron increased to $78.7
    million in 1997 from $70.0 million in 1996, primarily due to higher
    demand and, to a lesser extent, sales of $4.2 million from acquired
    businesses, offset in part by the unfavorable effects of currency
    translation. Sales at Thermedics Detection increased 17% to $51.3 million
    in 1997, primarily due to sales of its Alexus systems in connection with
    the completion of a mandated product-line upgrade from The Coca-Cola
    Company to its existing installed base, and $3.2 million of sales of
    explosives-detection systems to the U.S. Federal Aviation Administration.
    Thermedics Detection expects that sales of its Alexus systems will slow
    in 1998 due to the completion of the mandated upgrade for The Coca-Cola
    Company in 1997 and a decrease in demand for new installations. Sales at
    Thermo Voltek declined to $44.6 million in 1997 from $48.5 million in
    1996, primarily due to lower demand for electrostatic compatibility (EMC)
    test products, resulting from the declining influence of IEC 801, the

    European Union directive on electromagnetic compatibility that took
    effect January 1, 1996, and, to a lesser extent, a decline in the
    component-reliability market for electrostatic discharge test equipment
    that resulted from a slowdown in capital expenditures by the
    semiconductor industry. These decreases in revenues at Thermo Voltek were
    offset in part by sales of $5.8 million from acquired businesses. Sales
    from ThermoTrex's business units, including Trex Communications,
    increased $12.7 million in 1997 as a result of $6.9 million of sales from
    an acquired business at Trex Communications and, to a lesser extent,
    increased revenues from government contracts. 
        Segment income margin, excluding restructuring and other nonrecurring
    costs of $1.4 million in 1997, was 8.8% in 1997, compared with 7.5% in
    1996. This improvement resulted from increased sales and the impact in
    the 1996 period of charges for inventory obsolescence and other
    adjustments at Thermedics Detection, as well as a loss in the 1996 period
    at ThermoTrex's advanced-technology research center due to cost overruns
    and higher expenses for new lines of business. The improvement was offset
    in part by a decrease in profitability at Thermo Voltek and lower margins
    at Thermo Coleman as a result of increased sales of low-margin kiosk
    units and reduced revenues from government contracts. Restructuring and
    other nonrecurring costs of $1.4 million in 1997 were recorded by
    ThermoTrex for the write-off of acquired technology relating to an
    acquisition (Note 11).

    Gain on Issuance of Stock by Subsidiaries
    -----------------------------------------
        As a result of the sale of stock by subsidiaries and issuance of
    stock by subsidiaries upon conversion of convertible debentures, the
    Company recorded gains of $80.1 million in 1997 and $126.6 million in
    1996. See Notes 1 and 9 for a more complete description of these
    transactions. Minority interest expense increased to $74.4 million in
    1997 from $72.9 million in 1996. Minority interest expense includes $19.0
    million in 1997 and $38.2 million in 1996 related to gains recorded by
    the Company's majority-owned subsidiaries as a result of the sale of
    stock and the issuance of stock upon conversion of convertible
    debentures, by their subsidiaries.

    Contingent Liabilities and Other Matters
    ----------------------------------------
        At year-end 1997, the Company was contingently liable with respect to
    certain lawsuits (Note 6).
        The Company is currently assessing the potential impact of the year
    2000 on the processing of date-sensitive information by the Company's
    computerized information systems and on products sold as well as products
    purchased by the Company. The Company believes that its internal
    information systems and current products are either year 2000 compliant
    or will be so prior to the year 2000 without incurring material costs.
    There can be no assurance, however, that the Company will not experience
    unexpected costs and delays in achieving year 2000 compliance for its
    internal information systems and current products, which could result in
    a material adverse effect on the Company's future results of operations.

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

    1997 Compared With 1996 (continued)
        The Company is presently assessing the effect that the year 2000
    problem may have on its previously sold products. The Company is also
    assessing whether its key suppliers are adequately addressing this issue
    and the effect this might have on the Company. The Company has not
    completed its analysis and is unable to conclude at this time that the
    year 2000 problem as it relates to its previously sold products and
    products purchased from key suppliers is not reasonably likely to have a
    material adverse effect on the Company's future results of operations.

    1996 Compared With 1995
        Sales in 1996 were $2,932.6 million, an increase of $662.3 million,
    or 29%, over 1995. Segment income, excluding restructuring and other
    nonrecurring costs of $37.6 million in 1996 and $21.9 million in 1995,
    described below, increased 16% to $312.9 million in 1996 from $269.8
    million in 1995. Operating income, which includes restructuring and other
    nonrecurring costs, was $246.5 million in 1996, compared with $225.2
    million in 1995.

    Instruments
    -----------
        Sales from the Instruments segment were $1,209.4 million in 1996, an
    increase of $426.7 million, or 55%, over 1995. Sales increased primarily
    due to acquisitions made by Thermo Instrument, which added $404 million
    of sales in 1996. The unfavorable effects of currency translation due to
    the strengthening of the U.S. dollar relative to foreign currencies in
    countries in which Thermo Instrument operates decreased revenues by $21.8
    million in 1996. The remainder of the increase resulted primarily from
    greater demand at Thermo Instrument's mass spectrometry business as a
    result of recently introduced products and, to a lesser extent, greater
    demand at its Fourier transform infrared spectrometry business. 
        Segment income margin, excluding restructuring and other nonrecurring
    costs of $3.5 million in 1996, declined to 11.8% in 1996 from 14.5% in
    1995, primarily due to lower margins at acquired businesses.
    Restructuring and other nonrecurring costs of $3.5 million represents the
    write-off of acquired technology relating to the acquisition of the
    Fisons businesses (Note 11).

    Alternative-energy Systems
    --------------------------
        Sales from the Alternative-energy Systems segment were $339.8 million
    in 1996, compared with $325.9 million in 1995. Within this segment,
    revenues from Thermo Ecotek were $154.3 million in 1996, compared with
    $141.4 million in 1995. This increase resulted primarily from higher
    contractual energy rates at all of Thermo Ecotek's facilities, except the
    Hemphill plant in New Hampshire; increased revenues at the Delano plants
    in California resulting from fewer days of scheduled and unscheduled
    outages; and an acquisition that added $2.6 million in revenues. Revenues
    from the Company's waste-recycling facility in southern California were
    $9.2 million in 1996, compared with $20.8 million in 1995. This facility
    was sold in July 1996. Sales at Peter Brotherhood declined 3% to $54.4
    million as a result of lower demand for steam turbines. Sales from Thermo
    Power were $122.1 million in 1996, compared with $108.4 million in 1995.

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

    1996 Compared With 1995 (continued)
    This increase resulted primarily from increased demand for
    custom-designed industrial refrigeration packages, remanufactured
    commercial cooling equipment, and the inclusion of revenues from
    lift-truck engines, offset in part by declines in revenues from
    marine-engine products and rental equipment.
        Segment income, excluding restructuring and other nonrecurring costs
    of $4.4 million in 1996 and $11.5 million in 1995, was $42.5 million in
    1996, compared with $44.5 million in 1995. Thermo Ecotek had segment
    income of $39.3 million in 1996, compared with $34.6 million in 1995.
    This improvement results from increased revenues and, to a lesser extent,
    lower fuel costs. Segment income from the Company's waste-recycling
    facility, which was sold in July 1996, excluding restructuring and other
    nonrecurring costs of $11.5 million in 1995, was $4.6 million in 1996 and
    $5.9 million in 1995. Results from this facility, net of related interest
    expense (not included in segment income), were approximately at the
    breakeven level for both periods. Segment income at Thermo Power declined
    by $3.9 million to $1.1 million in 1996 due to a change in sales mix, a
    cost increase in one of the major components of its industrial
    refrigeration packages, higher depreciation expense at NuTemp, and higher
    warranty expenses for marine-engine products and at NuTemp. Peter
    Brotherhood incurred a segment loss of $2.5 million in 1996, excluding
    restructuring and other nonrecurring costs of $4.4 million, compared with
    a loss of $1.1 million in 1995. The decline resulted from increased costs
    to complete jobs in process as well as competitive pricing pressures.
    Peter Brotherhood recorded restructuring and other nonrecurring costs of
    $4.4 million in 1996 primarily for the write-off of a nontrade receivable
    and severance costs.
        Restructuring and other nonrecurring costs of $11.5 million in 1995
    represents the Company's net investment in a waste-recycling facility in
    southern California that contracted to process waste for San Diego County
    (the County) under a long-term service agreement. During the third
    quarter of 1995, the County paid the Company less than the amount due
    under the long-term service agreement, and in October 1995, the Company
    notified the County that the County was in default of the service
    agreement. The County was a party to the financing arrangements for the
    facility and was also in default of certain terms of such arrangements.
    As a result of the County's default under the service agreement and
    financing arrangements, the Company concluded that it would be unable to
    recover its investment in the facility. In 1996, in settlement of these
    matters, the facility was sold to the County for a nominal amount plus
    the County's assumption of the facility debt.

    Paper Recycling
    ---------------
        Sales in the Paper Recycling segment were $286.3 million in 1996,
    compared with $318.0 million in 1995. A wholly owned subsidiary of the
    Company recorded revenues from a contract to design and construct an
    office wastepaper de-inking facility of $58.0 million in 1996 and $77.0
    million in 1995. This contract was substantially completed in the second
    quarter of 1996. Sales from Thermo Fibertek declined 7%, to $192.2
    million in 1996. Thermo Fibertek's revenues under a subcontract from

                  Financial Condition and Results of Operations

    1996 Compared With 1995 (continued)
    Thermo Electron to supply equipment and services for the office
    wastepaper de-inking facility described above decreased $12.9 million.
    Revenues from Thermo Fibertek's recycling business declined an additional
    $7.5 million due to lower demand resulting from a severe drop in de-inked
    pulp prices, offset in part by $2.2 million of revenues from a business
    acquired during 1996. Revenues from Thermo Fibertek's accessories
    business increased $8.8 million primarily due to increased demand. The
    unfavorable effects of currency translation reduced Thermo Fibertek's
    revenues by $1.7 million in 1996. Sales of Thermo TerraTech's
    thermal-processing equipment increased $8.3 million in 1996 due to
    increased demand, while sales of automated electroplating equipment by
    the Company's wholly owned Napco subsidiary declined $6.4 million in
    1996.
        Segment income margin, excluding restructuring and other nonrecurring
    costs of $7.5 million in 1995, was 12.6% in 1996, compared with 11.5% in
    1995. This improvement resulted primarily from a nonrecurring payment
    received under the office wastepaper de-inking facility contract in 1996,
    which represented certain cost savings on the contract, and increased
    revenues from Thermo TerraTech's thermal-processing equipment business
    from depressed levels in 1995. Restructuring and other nonrecurring costs
    of $7.5 million in 1995 represent the write-off of cost in excess of net
    assets of acquired companies, of which $5.0 million was recorded by
    Thermo TerraTech, and $2.5 million was recorded by Napco (Note 11).

    Biomedical Products
    -------------------
        Sales in the Biomedical Products segment were $455.9 million in 1996,
    an increase of $139.3 million, or 44%, over 1995. Sales increased due to
    the inclusion of $111.7 million in sales from acquired businesses, as
    well as increased demand for certain products at Trex Medical, Thermo
    Cardiosystems' LVAS, and ThermoLase's hair-removal business.
        Segment income, excluding restructuring and other nonrecurring costs
    of $29.7 million in 1996, increased to $46.1 million in 1996 from $27.2
    million in 1995. This improvement resulted primarily from the inclusion
    of segment income from acquired businesses and increased sales at
    existing businesses. Restructuring and other nonrecurring costs of $29.7
    million in 1996 included a write-off of $12.7 million of cost in excess
    of net assets of acquired company and certain other intangible assets at
    Thermedics' Corpak subsidiary, $11.4 million of costs incurred by
    SensorMedics primarily as a result of its merger with the Company, $4.9
    million for Thermo Cardiosystem's write-off of acquired technology
    relating to a 1996 acquisition, and $0.7 million of other costs (Note
    11).

    Industrial Outsourcing
    ----------------------
        Sales in the Industrial Outsourcing segment were $273.9 million in
    1996, an increase of $63.4 million, or 30%, over 1995. Revenues from
    Thermo TerraTech's remediation and recycling services increased to $121.2
    million in 1996 from $67.5 million in 1995, primarily due to the
    inclusion of $53.9 million in revenues from acquired businesses. This
    increase was offset in part by a decline in revenues from soil-

                  Financial Condition and Results of Operations

    1996 Compared With 1995 (continued)
    remediation services of $4.9 million in 1996 due to declines in the
    volume of soil processed as a result of more relaxed regulatory standards
    in several states and competitive pricing pressures; and by a decline in
    revenues at Thermo TerraTech's radiochemistry laboratory businesses
    reflecting a reduction in spending at the U.S. Department of Energy and
    reduced federal government budget appropriations. Sales of metallurgical
    services were $45.7 million in 1996, compared with $42.8 million in 1995.
    Sales increased due to increased demand for existing services, offset in
    part by a decline of $2.9 million resulting from the closing of a small
    metallurgical services division in 1995.
        Segment income, excluding restructuring and other nonrecurring costs
    of $0.1 million in 1996 and $2.0 million in 1995, was $17.8 million in
    1996, compared with $23.2 million in 1995. Additional segment income from
    acquisitions was more than offset by costs incurred at Thermo TerraTech
    to reduce redundancies at regional laboratories and by costs incurred at
    Thermo EuroTech relating primarily to the settlement of several contract
    disputes, as well as the impact of severe winter weather in early 1996,
    which affected all phases of Thermo EuroTech's business, and by the
    effect of lower sales and income from the traditionally higher-margin
    soil-remediation services. Restructuring and other nonrecurring costs of
    $2.0 million in 1995 were recorded in connection with closing a
    metallurgical services division.

    Advanced Technologies
    ---------------------
        Sales from the Advanced Technologies segment were $375.5 million in
    1996, compared with $323.6 million in 1995. Sales increased $73.5 million
    due to the inclusion of sales from acquired businesses. These increases
    were offset in part by declines in revenues due to lower U.S. government
    contract funding at Thermo Coleman and ThermoTrex due to increased
    competition for government research and development funding.
        Segment income, excluding restructuring and other nonrecurring costs
    of $1.0 million in 1995, was $28.0 million in 1996, compared with $24.8
    million in 1995. Segment income provided by acquired companies and
    additional income from certain businesses were offset in part by lower
    segment income at Thermo Coleman, as a result of lower revenues, and by a
    loss incurred at ThermoTrex's advanced-technology research center due to
    cost overruns and higher expenses for new lines of business.
    Restructuring and other nonrecurring costs in 1995 primarily represent
    the write-off of intangible assets at ThermoTrex's East Coast division
    which was closed.

    Gain on Issuance of Stock by Subsidiaries
    -----------------------------------------
        As a result of the sale of stock by subsidiaries, the issuance of
    stock by subsidiaries upon conversion of convertible debentures, and
    similar transactions, the Company recorded gains of $126.6 million in
    1996 and $80.8 million in 1995. See Notes 1 and 9 for a more complete
    description of these transactions. Minority interest expense increased to
    $72.9 million in 1996 from $60.5 million in 1995. Minority interest
    expense includes $38.2 million in 1996 and $28.6 million in 1995 related
    to gains recorded by the Company's majority-owned subsidiaries as a
    result of the sale of stock and the issuance of stock upon conversion of
    convertible debentures, by their subsidiaries.

                  Financial Condition and Results of Operations

    Liquidity and Capital Resources

        Consolidated working capital was $2,002.0 million at January 3, 1998,
    compared with $2,218.6 million at December 28, 1996. Included in working
    capital were cash, cash equivalents, and short-term available-for-sale
    investments of $1,522.7 million at January 3, 1998, compared with
    $1,846.3 million at December 28, 1996. In addition, the Company had
    long-term available-for-sale investments of $63.3 million at January 3,
    1998, compared with $94.4 million at December 28, 1996. Of the total
    $1,586.0 million of cash, cash equivalents, and short- and long-term
    available-for-sale investments at January 3, 1998, $1,333.1 million was
    held by the Company's majority-owned subsidiaries and the balance was
    held by the Company and its wholly owned subsidiaries.
        During 1997, $269.0 million of cash was provided by operating
    activities. Cash of $86.5 million was used to fund an increase in
    accounts receivable, principally at Trex Medical, Thermo Instrument, and
    Thermo TerraTech. The increase in receivables at Trex Medical resulted
    primarily from increased sales and, to a lesser extent, longer customer
    payment patterns due to higher international sales and a shift to direct
    sales at a subsidiary. The increase in receivables at Thermo Instrument
    resulted from increased shipments in the fourth quarter at ThermoQuest
    and a competitive trend to commercial terms of 30 days from ThermoQuest's
    past practice of obtaining deposits on certain systems. The increase in
    receivables at Thermo TerraTech resulted from higher revenues at one
    business unit and a delay in the pursuit of collections at a second,
    which Thermo TerraTech expects to address in 1998 by expanding collection
    efforts. In addition, cash of $61.7 million was used to reduce other
    current liabilities, primarily for taxes and certain exit costs relating
    to acquisitions (Note 3).
        The Company's primary investing activities, excluding
    available-for-sale investments activity, included acquisitions, capital
    expenditures, and the sale of certain businesses and property, plant, and
    equipment. During 1997, the Company expended $849.1 million, net of cash
    acquired, for acquisitions and received a $36.1 million refund relating
    to a 1996 acquisition (Note 3). In addition, the Company sold certain
    businesses for net proceeds of $27.1 million. The Company expended $111.6
    million for purchases of property, plant, and equipment and received
    proceeds of $15.6 million from the sale of property, plant, and
    equipment.
        The Company's financing activities provided $237.8 million of cash in
    1997. Net proceeds from the issuance of Company and subsidiary common
    stock totaled $164.9 million, and net proceeds from the issuance of
    long-term obligations totaled $490.8 million. In addition, the Company
    repaid long-term obligations of $78.3 million.
        During 1997, an aggregate principal amount of $246.1 million of
    Company and subsidiary convertible obligations were converted into shares
    of Company and subsidiary common stock.
        In January 1998, Thermo Instrument issued and sold $250.0 million
    principal amount of 4% subordinated convertible debentures due 2005 for
    net proceeds of $243.8 million.

                  Financial Condition and Results of Operations

    Liquidity and Capital Resources (continued)

        The Company intends, for the foreseeable future, to maintain at least
    80% ownership of its Thermo Instrument and Thermo Ecotek subsidiaries,
    which is required in order to continue to file a consolidated federal
    income tax return with these subsidiaries. In addition, the Company
    intends to maintain greater than 50% ownership of its other
    majority-owned subsidiaries so that it may continue to consolidate these
    subsidiaries for financial reporting purposes. This may require the
    purchase by the Company of additional shares or convertible debentures of
    these companies from time to time as the number of outstanding shares
    issued by these companies increases, either in the open market or
    directly from the subsidiaries. See Note 5 for a description of
    outstanding convertible debentures issued by Thermo Instrument and Thermo
    Ecotek. In addition, at January 3, 1998, Thermo Instrument and Thermo
    Ecotek had outstanding stock options for 4,365,000 shares and 1,267,000
    shares, respectively, exercisable at various prices and subject to
    certain vesting schedules. The Company's other majority-owned
    subsidiaries also have outstanding stock options, convertible debentures,
    or both.
        During 1997, the Company and its majority-owned subsidiaries expended
    $311.1 million to purchase common stock and debentures of certain of the
    Company's majority-owned subsidiaries. These purchases were made pursuant
    to authorizations by the Company's and certain majority-owned
    subsidiaries' Boards of Directors. As of January 3, 1998, $13.1 million
    and $35.0 million remained under the Company's and its majority-owned
    subsidiaries' authorizations, respectively. Subsequent to January 3,
    1998, the Company and a majority-owned subsidiary received additional
    authorizations of $50.0 million and $10.0 million, respectively. The
    amount of purchases in a given reporting period may vary significantly.
        The Company has no material commitments for purchases of property,
    plant, and equipment and expects that, for 1998, expenditures on such
    items will approximate the 1997 level. Since January 3, 1998, a
    majority-owned subsidiary expended $4.5 million on the acquisition of a
    business and as of March 10, 1998, the Company's majority-owned
    subsidiaries had agreements or nonbinding letters of intent to acquire
    businesses for a total cost of approximately $67.5 million. Proposed
    acquisitions of new businesses are subject to various conditions to
    closing, and there can be no assurance that all proposed transactions
    will be consummated.
        As discussed above, a substantial percentage of the Company's
    consolidated cash and investments is held by subsidiaries that are not
    wholly owned by the Company. This percentage may vary significantly over
    time. Pursuant to the Thermo Electron Corporate Charter (the Charter), to
    which each of the majority-owned subsidiaries of the Company is a party,
    the combined financial resources of Thermo Electron and its subsidiaries
    allow the Company to provide banking, credit, and other financial
    services to its subsidiaries so that each member of the Thermo Electron
    group of companies may benefit from the financial strength of the entire
    organization. Toward that end, the Charter states that each member of the
    group may be required to provide certain credit support to the

    consolidated entity. This credit may rank junior, pari passu with, or
    senior in priority to payment of the other indebtedness of these members.
    Nonetheless, the Company's ability to access assets held by its
    majority-owned subsidiaries through dividends, loans, or other
    transactions is subject in each instance to a fiduciary duty owed to the
    minority shareholders of the relevant subsidiary. In addition, dividends
    received by Thermo Electron from a subsidiary that does not consolidate
    with Thermo Electron for tax purposes are subject to tax. Therefore,
    under certain circumstances, a portion of the Company's consolidated cash
    and short-term investments may not be readily available to Thermo
    Electron or certain of its subsidiaries.

    Market Risk

        The Company is exposed to market risk from changes in foreign
    currency exchange rates, interest rates, and equity prices, which could
    affect its future results of operations and financial condition. The
    Company manages its exposure to these risks through its regular operating
    and financing activities. Additionally, the Company uses short-term
    forward contracts to manage certain exposures to foreign currencies. The
    Company enters into forward foreign exchange contracts to hedge firm
    purchase and sale commitments denominated in currencies other than its
    subsidiaries' local currencies. The Company does not engage in extensive
    foreign currency hedging activities; however, the purpose of the
    Company's foreign currency hedging activities is to protect the Company's
    local currency cash flows related to these commitments from fluctuations
    in foreign exchange rates. The Company's forward foreign exchange
    contracts principally hedge transactions denominated in U.S. dollars,
    British pounds sterling, French francs, and Japanese yen. Gains and
    losses arising from forward contracts are recognized as offsets to gains
    and losses resulting from the transactions being hedged. The Company does
    not enter into speculative foreign currency agreements. 

    Foreign Currency Exchange Rates
        The fair value of forward foreign exchange contracts is sensitive to
    changes in foreign currency exchange rates. The fair value of forward
    foreign exchange contracts is the estimated amount that the Company would
    pay or receive upon termination of the contract, taking into account the
    change in foreign exchange rates. A 10% depreciation in year-end 1997
    foreign currency exchange rates related to the Company's contracts would
    result in a decrease in the unrealized gain on forward foreign exchange
    contracts of $3 million. Since the Company uses forward foreign exchange
    contracts as hedges of firm purchase and sale commitments, the unrealized
    gain or loss on forward foreign currency exchange contracts resulting
    from changes in foreign currency exchange rates would be offset by a
    corresponding change in the fair value of the hedged item.
        The Company generally views its investment in foreign subsidiaries
    with a functional currency other than the Company's reporting currency as
    long-term. The Company's investment in foreign subsidiaries is sensitive
    to fluctuations in foreign currency exchange rates. The functional

                  Financial Condition and Results of Operations

    Market Risk (continued)

    currencies of the Company's foreign subsidiaries are principally
    denominated in British pounds sterling, French francs, and German
    deutsche marks. The effect of a change in foreign exchange rates on the
    Company's net investment in foreign subsidiaries is recorded as a
    separate component of shareholders' investment. A 10% depreciation in
    year-end 1997 functional currencies, relative to the U.S. dollar, would
    result in a $27 million reduction of shareholders' investment.

    Interest Rates
        Certain of the Company's short- and long-term available-for-sale
    investments, long-term obligations, and interest rate swap agreements are
    sensitive to changes in interest rates. Interest rate changes would
    result in a change in the fair value of these financial instruments due
    to the difference between the market interest rate and the rate at the
    date of purchase or issuance of the financial instrument. A 10% decrease
    in year-end 1997 market interest rates would result in a negative impact
    of $18 million on the net fair value of the Company's interest-sensitive
    financial instruments.

    Equity Prices
        The Company's available-for-sale investment portfolio includes equity
    securities that are sensitive to fluctuations in price. In addition, the
    Company's and its subsidiaries' convertible obligations are sensitive to
    fluctuations in the price of Company or subsidiary common stock into
    which the obligations are convertible. Changes in equity prices would
    result in changes in the fair value of the Company's available-for-sale
    investments and convertible obligations due to the difference between the
    current market price and the market price at the date of purchase or
    issuance of the financial instrument. A 10% increase in the year-end 1997
    market equity prices would result in a negative impact of $96 million on
    the net fair value of the Company's price-sensitive equity financial
    instruments.

                           Forward-looking Statements

        In connection with the "safe harbor" provisions of the Private
    Securities Litigation Reform Act of 1995, the Company wishes to caution
    readers that the following important factors, among others, in some cases
    have affected, and in the future could affect, the Company's actual
    results and could cause its actual results in 1998 and beyond to differ
    materially from those expressed in any forward-looking statements made
    by, or on behalf of, the Company.

        Risks Associated with Acquisition Strategy. One of the Company's
    principal growth strategies is to supplement its internal growth with the
    acquisition of businesses and technologies that complement or augment the
    Company's existing product lines. Certain businesses recently acquired by
    the Company have had low levels of profitability. In addition, businesses
    that the Company may seek to acquire in the future may also be marginally
    profitable or unprofitable. In order for any acquired businesses to
    achieve the level of profitability desired by the Company, the Company
    must successfully change operations and improve market penetration. No
    assurance can be given that the Company will be successful in this
    regard. In addition, promising acquisitions are difficult to identify and
    complete for a number of reasons, including competition among prospective
    buyers, the need for regulatory approvals, including antitrust approvals,
    and the high valuations of businesses resulting from historically high
    stock prices in many countries. Acquisitions completed by the Company may
    be made at substantial premiums over the fair value of the net assets of
    the acquired companies. There can be no assurance that the Company will
    be able to complete pending or future acquisitions or that the Company
    will be able to successfully integrate any acquired businesses into its
    existing business or make such businesses profitable. In order to finance
    any such acquisitions, it may be necessary for the Company to raise
    additional funds either through public or private financings. Any equity
    or debt financing, if available at all, may be on terms which are not
    favorable to the Company and may result in dilution to the Company's
    shareholders.

        Risks Associated with Spinout of Subsidiaries. The Company has
    adopted a strategy of spinning out certain of its businesses into
    separate subsidiaries and having these subsidiaries sell a minority
    interest to outside investors. As a result of the sale of stock by
    subsidiaries, the issuance of stock by subsidiaries upon conversion of
    convertible debentures, and similar transactions, the Company records
    gains that represent the increase in the Company's net investment in the
    subsidiaries. These gains have represented a substantial portion of the
    net income reported by the Company in certain periods. The size and
    timing of these transactions are dependent on market and other conditions
    that are beyond the Company's control. Accordingly, there can be no
    assurance that the Company will be able to generate gains from such
    transactions in the future.
        Further, in October 1995, the Financial Accounting Standards Board
    (FASB) issued an exposure draft of a Proposed Statement of Financial
    Accounting Standards, "Consolidated Financial Statements: Policy and
    Procedures" (the Proposed Statement). The Proposed Statement would
    establish new rules for how consolidated financial statements should be

                                       64PAGE
<PAGE>
    Thermo Electron Corporation                     1997 Financial Statements

                           Forward-looking Statements

    prepared. If the Proposed Statement is adopted, there would be
    significant changes in the way the Company records certain transactions
    of its controlled subsidiaries. Among those changes, any sale of the
    stock of a subsidiary that does not result in a loss of control would be
    accounted for as a transaction in the equity of the consolidated entity
    with no gain or loss being recorded. The exposure draft addresses the
    consolidation issues in two parts: consolidation procedures, which
    includes proposed rule changes affecting the Company's ability to
    recognize gains on issuances of subsidiary stock, and consolidation
    policy, which does not address accounting for such gains. During 1997,
    the FASB decided to focus its efforts on the consolidation policy part of
    the exposure draft and to consider resuming discussion on consolidation
    procedures after completion of the efforts on consolidation policy. The
    timing and content of any final statement are uncertain.

        Competition. The Company encounters and expects to continue to
    encounter significant competition in the sale of its products and
    services. The Company's competitors include a number of large
    multinational corporations, some of which may be able to adapt more
    quickly to new or emerging technologies and changes in customer
    requirements, or to devote greater resources to the promotion and sale of
    their products than the Company. Competition could increase if new
    companies enter the market or if existing competitors expand their
    product lines or intensify efforts within existing product lines. There
    can be no assurance that the Company's current products, products under
    development, or ability to develop new technologies will be sufficient to
    enable it to compete effectively.

        Risks Associated with International Operations. International
    revenues account for a substantial portion of the Company's revenues, and
    the Company intends to continue to expand its presence in international
    markets. International revenues are subject to a number of risks,
    including the following: fluctuations in exchange rates may affect
    product demand and adversely affect the profitability in U.S. dollars of
    products and services provided by the Company in foreign markets where
    payment for the Company's products and services is made in the local
    currency; agreements may be difficult to enforce and receivables
    difficult to collect through a foreign country's legal system; foreign
    customers may have longer payment cycles; foreign countries may impose
    additional withholding taxes or otherwise tax the Company's foreign
    income, impose tariffs, or adopt other restrictions on foreign trade;
    U.S. export licenses may be difficult to obtain; and the protection of
    intellectual property in foreign countries may be more difficult to
    enforce. There can be no assurance that any of these factors will not
    have a material adverse impact on the Company's business and results of
    operations.

        Rapid and Significant Technological Change and New Products. The
    markets for the Company's products are characterized by rapid and
    significant technological change, evolving industry standards and
    frequent new product introductions and enhancements. Many of the
    Company's products and products under development are technologically 

                                       65PAGE

    innovative and require significant planning, design, development, and
    testing at the technological, product, and manufacturing-process levels.
    These activities require significant capital commitments and investment
    by the Company. In addition, products that are competitive in the
    Company's markets are characterized by rapid and significant
    technological change due to industry standards that may change on short
    notice and by the introduction of new products and technologies that
    render existing products and technologies uncompetitive or obsolete.
    There can be no assurance that any of the products currently being
    developed by the Company, or those to be developed in the future, will be
    technologically feasible or accepted by the marketplace, that any such
    development will be completed in any particular time frame, or that the
    Company's products or proprietary technologies will not become
    uncompetitive or obsolete. 

        Possible Adverse Effect from Changes in Governmental Regulations. The
    Company competes in several markets which involve compliance by its
    customers with federal, state, local, and foreign regulations, such as
    environmental, health and safety, and food and drug regulations. The
    Company develops, configures, and markets its products to meet customer
    needs created by such regulations. These regulations may be amended or
    eliminated in response to new scientific evidence or political or
    economic considerations. Any significant change in regulations could
    adversely affect demand for the Company's products in regulated markets.

        Government Regulation; No Assurance of Regulatory Approvals. Certain
    of the Company's products are subject to pre-marketing clearance or
    approval by the U.S. Food and Drug Administration (FDA) and similar
    agencies in foreign countries. The use or sale of certain of the
    Company's products under development may require approvals by other
    government agencies. The process of obtaining clearance and approval from
    the FDA and other government agencies is time-consuming and expensive.
    Furthermore, there can be no assurance that the necessary clearances or
    approvals for the Company's products, services, and products and services
    under development will be obtained on a timely basis, if at all.
        FDA regulations also require continuing compliance with specific
    standards in conjunction with the maintenance and marketing of products
    and services that have been approved or cleared. Failure to comply with
    applicable regulatory requirements can result in, among other things,
    civil and criminal penalties, suspension of approvals, recalls, or
    seizures of products, injunctions, and criminal prosecutions.
        Risks Associated with Dependence on Capital Spending Policies and
    Government Funding. The Company's customers include pharmaceutical and
    chemical companies, laboratories, universities, healthcare providers,
    paper manufacturers, consumer product companies, government agencies, and
    public and private research institutions. The capital spending of these
    entities can have a significant effect on the demand for the Company's
    products. Such spending is based on a wide variety of factors, including
    the resources available to make purchases, the spending priorities among
    various types of equipment, public policy, and the effects of different
    economic cycles. Any decrease in capital spending by any of the customer
    groups that account for a significant portion of the Company's sales
    could have a material adverse effect on the Company's business and
    results of operations.

                           Forward-looking Statements

        Dependence on Patents and Proprietary Rights. The Company places
    considerable importance on obtaining patent and trade secret protection
    for significant new technologies, products, and processes because of the
    length of time and expense associated with bringing new products through
    the development process and to the marketplace. The Company's success
    depends in part on its ability to develop patentable products and obtain
    and enforce patent protection for its products both in the United States
    and in other countries. The Company owns numerous United States and
    foreign patents, and intends to file additional applications for patents
    as appropriate to cover its products. No assurance can be given that
    patents will issue from any pending or future patent applications owned
    by or licensed to the Company or that the claims allowed under any issued
    patents will be sufficiently broad to protect the Company's technology.
    In addition, no assurance can be given that any issued patents owned by
    or licensed to the Company will not be challenged, invalidated, or
    circumvented, or that the rights granted thereunder will provide
    competitive advantages to the Company. There can be no assurance that
    third parties will not assert claims against the Company that the Company
    infringes the intellectual property rights of such parties. The Company
    could incur substantial costs and diversion of management resources with
    respect to the defense of any such claims, which could have a material
    adverse effect on the Company's business, financial condition, and
    results of operations. Furthermore, parties making such claims could
    secure a judgment awarding substantial damages, as well as injunctive or
    other equitable relief, which could effectively block the Company's
    ability to make, use, sell, distribute, or market its products and
    services in the United States or abroad. In the event that a claim
    relating to intellectual property is asserted against the Company, the
    Company may seek licenses to such intellectual property. There can be no
    assurance, however, that such licenses could be obtained on commercially
    reasonable terms, if at all. The failure to obtain the necessary licenses
    or other rights could preclude the sale, manufacture, or distribution of
    the Company's products and, therefore, could have a material adverse
    effect on the Company's business, financial condition, and results of
    operations.
        The Company relies on trade secrets and proprietary know-how, which
    it seeks to protect, in part, by confidentiality agreements with its
    collaborators, employees, and consultants. There can be no assurance that
    these agreements will not be breached, that the Company would have
    adequate remedies for any breach, or that the Company's trade secrets
    will not otherwise become known or be independently developed by
    competitors.
        ThermoQuest's Finnigan subsidiary has filed complaints against
    Bruker-Franzen Analytik GmbH and its U.S. affiliate, and Hewlett-Packard
    Company, for alleged violation of two U.S. patents owned by Finnigan
    pertaining to methods used in ion-trap mass spectrometers. One of
    Finnigan's complaints was filed in United States District Court and the
    other was filed with the United States International Trade Commission
    (ITC). In February 1998, an administrative law judge at the ITC issued an
    initial determination to the effect that, although one of Finnigan's
    patents was infringed, the patents were invalid for purposes of this
    case. The ITC's jurisdiction on this matter is limited to the issue of

                                       67PAGE

                           Forward-looking Statements

    whether or not the defendants' products that use the patented methods can
    be imported into the U.S. The judge's initial determination will be
    considered by the full commission during the second quarter of 1998.
    Bruker has presented counterclaims alleging that the Finnigan patents are
    invalid and unenforceable and are not infringed by the mass spectrometers
    co-marketed by Bruker. They also allege that Finnigan has violated
    antitrust laws by attempting to maintain a monopoly position and restrain
    trade through enforcement of allegedly fraudulently obtained patents.
    Bruker has asked for judgment consistent with its counterclaims, and for
    three times the antitrust damages (including attorney's fees) it has
    sustained.
        There can be no assurance as to the outcome of this matter. While the
    Company believes that any resolution of this matter will not materially
    affect its financial position, an unfavorable resolution could have a
    material adverse effect on the Company's future results of operations.

        Potential Impact of Year 2000 on Processing of Date-sensitive
    Information. The Company is currently assessing the potential impact of
    the year 2000 on the processing of date-sensitive information by the
    Company's computerized information systems and on products sold as well
    as products purchased by the Company. The Company believes that its
    internal information systems and current products are either year 2000
    compliant or will be so prior to the year 2000 without incurring material
    costs. There can be no assurance, however, that the Company will not
    experience unexpected costs and delays in achieving year 2000 compliance
    for its internal information systems and current products, which could
    result in a material adverse effect on the Company's future results of
    operations.
        The Company is presently assessing the effect that the year 2000
    problem may have on its previously sold products. The Company is also
    assessing whether its key suppliers are adequately addressing this issue
    and the effect this might have on the Company. The Company has not
    completed its analysis and is unable to conclude at this time that the
    year 2000 problem as it relates to its previously sold products and
    products purchased from key suppliers is not reasonably likely to have a
    material adverse effect on the Company's future results of operations.
