    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 April 2, 1998, the
    Company had 28 subsidiaries that have sold minority equity interests, 23
    of which are publicly traded and 5 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.

        (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.

        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, Thermo Vision Corporation, and ONIX Systems Inc. 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.

    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
    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, which became a public subsidiary of Thermo Instrument
    in March 1998, 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.

        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.

        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

    diverse medical products businesses, both wholly and publicly owned, that
    supply a wide range of medical systems and devices for diagnostic
    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.

        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.,

    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,
    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
    construction and reconstruction, and natural resource management. Thermo
    TerraTech also offers comprehensive environmental testing and analysis
    through a national network of laboratories serving the pharmaceutical,
    food, and environmental industries.

        Thermo Remediation Inc., a public subsidiary of Thermo TerraTech, is
    a national provider of outsourcing services for environmental management,
    including industrial, nuclear, and soil remediation, as well as
    waste-fluids recycling, primarily helping clients manage problems
    associated with environmental compliance, waste management, and the
    cleanup of sites contaminated with organic or toxic wastes.

        The Randers Group Incorporated, also a public subsidiary of Thermo
    TerraTech, provides comprehensive engineering and outsourcing services in
    such areas as water and wastewater treatment, highway and bridge
    projects, process engineering, construction management, and operational
    services.

        A privately held subsidiary of Thermo TerraTech, Thermo EuroTech
    N.V., provides remediation and recycling services in Europe. The Company
    treats oil-based contaminated soils and recycles waste oil and oily waste
    streams. In February 1998, Thermo EuroTech acquired a controlling
    interest in an Irish environmental services company that provides
    comprehensive in-plant waste management and recycling services to
    high-tech manufacturing firms in that country.

        In addition, metallurgical heat-treating services are provided by a
    wholly owned subsidiary of the Company for customers in the automotive,
    aerospace, defense, and other industries. The Company also provides,
    through another wholly owned business, metallurgical fabrication
    services, principally on high-temperature materials, for customers in the
    aerospace, medical, electronics, and nuclear industries.

    Advanced Technologies

        The Company's Advanced Technologies segment includes basic and
    applied research and development, often sponsored by the U.S. government,
    that is conducted with a goal of identifying viable commercial
    opportunities for new ventures. A number of its subsidiaries also provide
    various instrument systems, developed primarily for product
    quality-assurance applications in industrial, food and beverage,
    pharmaceutical, and electronics markets.

        The Company's ThermoTrex subsidiary conducts sponsored research and
    development with the goal of commercializing new products based on
    advanced technologies developed in its laboratories. Sponsored research
    and development, conducted principally for the U.S. government, includes
    basic and applied research in communications, avionics, X-ray detection,
    signal processing, advanced-materials technology, and lasers.

    food-processing and pharmaceutical companies. Its bulk-materials product
    line includes conveyor-belt scales, solid level-measurement and
    conveyor-monitoring systems, and sampling systems, all sold to customers
    in the mining and material-processing industries, as well as to electric
    utilities, chemical, and other manufacturing companies.

        Thermedics Detection Inc., another public subsidiary of Thermedics,
    develops and manufactures high-speed on-line analysis systems used for
    product quality assurance in a variety of industrial processes, as well
    as for security. Thermedics Detection provides X-ray imaging systems that
    monitor a wide range of containers for fill volume, net volume, and
    package integrity, as well as systems that detect trace amounts of
    contaminants in refillable bottles, specifically for the beverage
    industry. For the beverage, food, cosmetic, and other industries,
    Thermedics Detection also makes instruments that use near-infrared
    spectroscopy to measure moisture and other product components, including
    fat, protein, solvents, and other substances in numerous consumer and
    industrial products. Thermedics Detection recently introduced an
    ultrahigh-speed gas chromatograph that permits manufacturers to conduct
    laboratory-quality analysis for near-on-line process-control
    applications.

        Thermo Voltek Corp., also a public subsidiary of Thermedics, designs,
    manufactures, and markets test instruments and a range of products
    related to power amplification, conversion, and quality. Thermo Voltek's
    power products are used in communications, broadcast, research, and
    medical imaging applications. Its test instruments allow manufacturers of
    electronic systems and integrated circuits to test for electromagnetic
    compatibility. On March 30, 1998, Thermedics approved a proposal to
    acquire, through a merger, all of the outstanding shares of common stock
    of Thermo Voltek that Thermedics does not own at a price of $7.00 per
    share in cash. The total transaction cost to Thermedics is estimated to
    be approximately $27 million, which includes approximately $5.25 million
    for the redemption of the outstanding Thermo Voltek 3 3/4 percent
    convertible subordinated debentures due 2000. The merger is contingent
    upon, among other things, the negotiation and execution of a definitive
    merger agreement; receipt by the Thermo Voltek board of directors of an
    opinion by an investment banking firm that Thermedics' offer is fair to
    Thermo Voltek shareholders (other than Thermedics and the Company) from a
    financial point of view; the approval of the Thermo Voltek board of
    directors upon recommendation of a special committee of its independent
    directors; and clearance by the Securities and Exchange Commission of the
    proxy materials regarding the proposed transaction. On March 31, 1998,
    two complaints naming the Company as a defendant, among others, regarding
    Thermedics' proposed acquisition of Thermo Voltek were filed in Delaware
    Chancery Court by two Thermo Voltek shareholders attempting to act on
    behalf of the other public shareholders of Thermo Voltek. The complaints
    allege, among other things, that the proposed price of $7.00 per share is
    unfair and grossly inadequate.  

        Through a wholly owned subsidiary, Thermedics manufactures
    electrode-based chemical-measurement products used in the agricultural,
    biomedical research, food processing, pharmaceutical, sewage treatment,

    and many other industries. In laboratories, manufacturing plants, and in
    the field, Thermedics' products permit these industries to determine the
    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.

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Significant Accounting Policies

    Nature of Operations
        Thermo Electron Corporation and its subsidiaries (the Company)

    other specialized products. The Company also provides industrial
    outsourcing, laboratory, and metallurgical services, and conducts
    advanced-technology research and development.

    Principles of Consolidation
        The accompanying financial statements include the accounts of Thermo
    Electron and its majority- and wholly owned subsidiaries. All material
    intercompany accounts and transactions have been eliminated.
    Majority-owned public subsidiaries consist of Thermedics Inc., Thermo
    Instrument Systems Inc., Thermo TerraTech Inc., Thermo Power Corporation,
    ThermoTrex Corporation, Thermo Fibertek Inc., and Thermo Ecotek
    Corporation. Thermo Cardiosystems Inc., Thermo Voltek Corp., Thermo
    Sentron Inc., and Thermedics Detection Inc. are majority-owned, public
    subsidiaries of Thermedics. ThermoSpectra Corporation, ThermoQuest
    Corporation, Thermo Optek Corporation, Thermo BioAnalysis Corporation,
    Metrika Systems Corporation, and Thermo Vision Corporation are
    majority-owned, public subsidiaries of Thermo Instrument. Thermo
    Remediation Inc. and The Randers Group Incorporated are majority-owned,
    public subsidiaries of Thermo TerraTech. ThermoLase Corporation and Trex
    Medical Corporation are majority-owned, public subsidiaries of

    owns between 20% and 50% using the equity method.

    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
    included 52 weeks.

    Revenue Recognition
        For the majority of its operations, the Company recognizes revenues
    upon shipment of its products, or upon completion of services it renders.
    The Company provides a reserve for its estimate of warranty and
    installation costs at the time of shipment. Deferred revenue in the

                   Notes to Consolidated Financial Statements

    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

                                       17PAGE

    3.  Acquisitions (continued)

    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.

    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

    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
    expense $9.3 million, $8.8 million, and $8.2 million in 1997, 1996, and
    1995, respectively.

        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:

        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. Simultaneous 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

    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,

                   Notes to Consolidated Financial Statements

   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

        obligations       $1,660,839   $1,856,570   $1,379,467  $1,616,239

                          ----------   ----------   ----------  ----------
                          $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.

                     Management's Discussion and Analysis of
                  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 systems, 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,

                  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

                  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

    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, 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.

                  Financial Condition and Results of Operations

    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 an
    $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 physician-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.

                  Financial Condition and Results of Operations

    1997 Compared With 1996 (continued)
        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(R) 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 Cardiosystems' 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

                  Financial Condition and Results of Operations

    1997 Compared With 1996 (continued)
    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. 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 Cardiosystems' 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
                                       61PAGE

    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
                                       62PAGE

                  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

    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.

        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.
