    Thermo Power Corporation                        1997 Financial Statements

                   Notes to Consolidated Financial Statements

    1.  Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations
        Thermo Power Corporation (the Company) manufactures, markets, and
    services industrial refrigeration equipment, natural gas engines for
    vehicular and stationary applications, marine engines, fork-lift engines,
    and natural gas-fueled commercial cooling and cogeneration systems. The
    Company also conducts research and development on applications of thermal
    energy and rents commercial cooling and industrial refrigeration
    equipment. In addition, the Company is developing and commercializing
    various gas-powered lighting products.

    Relationship with Thermo Electron Corporation
        The Company was incorporated on June 6, 1985, as a wholly owned
    subsidiary of Thermo Electron Corporation. As of September 27, 1997,
    Thermo Electron owned 8,127,906 shares of the Company's common stock,
    representing 68% of such stock outstanding.

    Principles of Consolidation
        The accompanying financial statements include the accounts of the
    Company, its wholly owned subsidiaries, and its 78%-owned privately held
    subsidiary, ThermoLyte Corporation. All material intercompany accounts
    and transactions have been eliminated.

    Fiscal Year
        The Company has adopted a fiscal year ending the Saturday nearest
    September 30. References to fiscal 1997, 1996, and 1995 are for the
    fiscal years ended September 27, 1997, September 28, 1996, and September
    30, 1995, respectively. 

    Revenue Recognition
        The Company recognizes revenues upon shipment of its products or upon
    completion of services it renders, and recognizes rental revenues on a
    straight-line basis over the term of the rental contract. The Company
    provides a reserve for its estimate of warranty costs at the time of
    shipment. Revenues and profits on contracts are recognized using the
    percentage-of-completion method. Revenues recorded under the percentage-
    of-completion method, including revenues from research and development
    contracts, were $60,590,000 in fiscal 1997, $57,842,000 in fiscal 1996,
    and $53,045,000 in fiscal 1995. The percentage of completion is
    determined by relating the actual costs incurred to date to management's
    estimate of total costs 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. Contracts at the Company's FES division generally
    provide for the billing of customers on a fixed-price basis upon contract
    completion. Contracts at the Company's Tecogen division generally provide
    for the billing of customers on a cost-plus-fixed-fee basis as costs are
    incurred. Revenues earned on contracts in process in excess of billings
    are classified as unbilled contract costs and fees, and amounts billed in
    excess of revenues are classified as billings in excess of contract costs
    and fees in the accompanying balance sheet. There are no significant
    amounts included in the accompanying balance sheet that are not expected

        (continued)

    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.

    Research and Development Arrangements
        The Company has research and development arrangements with the
    natural gas industry and various government agencies. Revenues in the
    accompanying statement of income include $4,688,000, $5,836,000, and
    $4,917,000 and cost of revenues include $3,776,000, $4,475,000, and
    $3,548,000 related to these arrangements in fiscal 1997, 1996, and 1995,
    respectively. The Company is required to pay royalties for any
    technologies developed or products commercialized under several of these
    arrangements. Selling, general, and administrative expenses in the
    accompanying statement of income include royalty expense related to these
    arrangements of $65,000, $71,000, and $51,000 in fiscal 1997, 1996, and
    1995, respectively.

    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
        Earnings per share have been computed based on the weighted average
    number of shares outstanding during the year. Because the effect of the
    assumed exercise of stock options would be immaterial, they have been
    excluded from the earnings per share calculation.

    Cash and Cash Equivalents
        As of September 27, 1997, $17,994,000 of the Company's cash
    equivalents were invested in a repurchase agreement with Thermo Electron.
    Under this agreement, the Company in effect lends excess cash to Thermo
    Electron, which Thermo Electron collateralizes with investments
    principally consisting of U.S. government-agency securities, corporate
    notes, commercial paper, money market funds, and other marketable
    securities, in the amount of at least 103% of such obligation. The
    Company's funds subject to the repurchase agreement are readily

    convertible into cash by the Company. The repurchase agreement earns a
    rate based on the 90-day Commercial Paper Composite Rate plus 25 basis
    points, set at the beginning of each quarter. Cash equivalents are
    carried at cost, which approximates market value.

    Available-for-sale Investments
        Pursuant to SFAS No. 115, "Accounting for Certain Investments in Debt
    and Equity Securities," effective October 2, 1994, the Company's debt and
    marketable equity securities are accounted for at market value (Note 2).

    Inventories
        Inventories are stated at the lower of cost (on a first-in, first-out
    basis) or market value and include materials, labor, and manufacturing
    overhead. The components of inventories are as follows:

    Rental Assets
        The costs of additions and improvements are capitalized, while
    maintenance and repairs are charged to expense as incurred. The Company
    provides for depreciation on rental assets over an estimated useful life
    of seven years. Accumulated depreciation was $3,369,000 and $2,378,000 at
    fiscal year-end 1997 and 1996, respectively.

    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, 40
    years; machinery and equipment, 3 to 12 years; and leasehold
    improvements, the shorter of the term of the lease or the life of the
    asset. Property, plant, and equipment consists of the following:

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

    Cost in Excess of Net Assets of Acquired Companies
        The excess of cost over the fair value of net assets of acquired
    companies is amortized using the straight-line method over 40 years.
    Accumulated amortization was $710,000 and $512,000 at fiscal 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 Subsidiary Subject to Redemption
        In March 1995, ThermoLyte sold 1,845,000 units, each unit consisting
    of one share of ThermoLyte common stock, $.001 par value, and one
    redemption right, at $10.00 per unit, for net proceeds of $17,253,000.
    Holders of the common stock purchased in the offering will have the
    option to require ThermoLyte to redeem in December 1998 or 1999 any or
    all of their shares at $10.00 per share. The redemption rights are
    guaranteed on a subordinated basis by Thermo Electron. The Company has
    agreed to reimburse Thermo Electron in the event Thermo Electron is
    required to make a payment under the guarantee. The difference between
    the redemption value and the original carrying amount of common stock of
    subsidiary subject to redemption is accreted using the straight-line
    method over the period ending December 1998, which corresponds to the
    first redemption period. The accretion is charged to minority interest
    expense in the accompanying statement of income. ThermoLyte is developing
    various gas-powered lighting products for commercialization. Following
    the offering, the Company owned 78% of ThermoLyte's outstanding common
    stock.

    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 fiscal 1996 and 1995 have been reclassified to
    conform to the presentation in the fiscal 1997 financial statements.

    2.  Available-for-sale Investments

        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

        Short- and long-term available-for-sale investments in the
    accompanying fiscal 1997 balance sheet include equity securities of
    $2,200,000 and debt securities of $9,171,000 with contractual maturities
    of more than one year through five years. Actual maturities may differ
    from contractual maturities as a result of the Company's intent to sell
    these securities prior to maturity and as a result of put and call
    options that enable 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. Gain on sale of
    investments, net, in the accompanying fiscal 1997 statement of income
    resulted from gross realized gains relating to the sale of available-for-
    sale investments. Gain on sale of investments, net, in the accompanying
    fiscal 1996 and 1995 statement of income resulted from gross realized
    gains of $469,000 and 768,000, respectively, and gross realized losses of
    $18,000 and $38,000, respectively, relating to the sale of
    available-for-sale investments, and a write-down of other investments of
    $243,000 in fiscal 1996.

    3.  Acquisitions

        In the first quarter of fiscal 1996, the Company acquired the
    thermoelectric cooling module business of ThermoTrex Corporation for
    $860,000, which was the net book value of the business acquired.
    ThermoTrex is a majority-owned subsidiary of Thermo Electron. Because the
    Company and the thermoelectric cooling module business were deemed for
    accounting purposes to be under control of their common majority owner,
    Thermo Electron, the transaction has been accounted for at historical
    cost in a manner similar to the pooling-of-interests method. The results
    of the thermoelectric cooling module business were not material to the
    Company's results, and therefore the Company's historical financial
    information for periods prior to fiscal 1996 has not been restated. The
    results of the thermoelectric cooling module business have been included
    in the accompanying financial statements from the date of acquisition.
        Effective May 1, 1994, the Company acquired NuTemp, Inc. for
    $7,947,000 in cash. In fiscal 1995, the Company paid an additional
    $2,500,000 as a result of NuTemp having achieved certain previously
    agreed upon performance goals through the period ending May 1, 1995. The
    additional payment was recorded as an increase in cost in excess of net
    assets of acquired companies, which is being amortized over 40 years.

    Stock-based Compensation Plans

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

   Employee Stock Purchase Program
   -------------------------------
       Substantially all of the Company's full-time employees are eligible
   to participate in an employee stock purchase program sponsored by the
   Company and Thermo Electron. Under this program, shares of the Company's
   and Thermo Electron'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, the applicable shares of 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. During fiscal 1997, 1996,
   and 1995, the Company issued 4,622 shares, 18,012 shares, and 25,859
   shares, respectively, of its common stock under this program.

   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 fiscal 1997 and 1996 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:

                   Notes to Consolidated Financial Statements

    4.  Employee Benefit Plans (continued)

        Because the method prescribed by SFAS No. 123 has not been applied to
    options granted prior to October 1, 1995, the resulting pro forma
    compensation expense may not be representative of the amount to be
    expected in future years. 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 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
    -----------------------------------------------------------------------
    Volatility                                              43%         43%
    Risk-free interest rate                                6.0%        5.7%
    Expected life of options                          4.2 years   3.3 years

       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 and Employee Stock Ownership Plan
        The majority of the Company's employees are eligible to participate
    in Thermo Electron's 401(k) savings plan and, prior to January 1, 1995,
    certain employees were eligible to participate in Thermo Electron's
    employee stock ownership plan (ESOP). Contributions to the 401(k) savings
    plan are made by both the employee and the Company. Company contributions
    are based upon the level of employee contributions. For these plans, the
    Company contributed and charged to expense $666,000, $674,000, and
    $653,000 in fiscal 1997, 1996, and 1995, respectively. Effective December
    31, 1994, the ESOP was split into two plans: ESOP I, covering employees
    of Thermo Electron's corporate office and its wholly owned subsidiaries,
    and ESOP II, covering employees of certain of Thermo Electron's
    majority-owned subsidiaries, including the Company. Also, effective
    December 31, 1994, the ESOP II plan was terminated, and as a result, the
    Company's employees are no longer eligible to participate in an ESOP.

        The Company receives a tax deduction upon exercise of nonqualified
    stock options by employees for the difference between the exercise price
    and the market price of the Company's common stock on the date of
    exercise. The provision for income taxes that is currently payable does
    not reflect $764,000, $492,000, and $153,000 of such benefits that have
    been allocated to capital in excess of par value in fiscal 1997, 1996,
    and 1995, respectively.
        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 34% to income before provision for income
    taxes and minority interest due to the following:

        The valuation allowance relates to the uncertainty surrounding the
    realization of net operating loss carryforwards and other tax assets of
    the Company's ThermoLyte subsidiary. As of September 27, 1997, ThermoLyte
    had net operating loss carryforwards of approximately $1.1 million that
    begin to expire in fiscal 2011.

    6.  Related-party Transactions

    Corporate Services Agreement
        The Company and Thermo Electron have a corporate services agreement
    under which Thermo Electron's corporate staff provides certain
    administrative services, including certain legal advice and services,
    risk management, certain employee benefit administration, tax advice and
    preparation of tax returns, centralized cash management, and certain
    financial and other services, for which the Company pays Thermo Electron
    annually an amount equal to 1.0% of the Company's revenues. The Company
    paid an annual fee equal to 1.20% and 1.25% of the Company's revenues in
    calendar year 1995 and 1994, respectively. The annual fee is reviewed and
    adjusted annually by mutual agreement of the parties. For these services,
    the Company was charged $1,210,000, $1,262,000, and $1,250,000 in fiscal
    1997, 1996, and 1995, respectively. The corporate services agreement is
    renewed annually but can be terminated upon 30 days' prior notice by the
    Company or upon the Company's withdrawal from the Thermo Electron
    Corporate Charter (the Thermo Electron Corporate Charter defines the
    relationships among Thermo Electron and its majority-owned subsidiaries).
    Management believes that the service fee charged by Thermo Electron is
    reasonable and that such fees are representative of the expenses the
    Company would have incurred on a stand-alone basis. For additional items
    such as employee benefit plans, insurance coverage, and other
    identifiable costs, Thermo Electron charges the Company based upon costs
    attributable to the Company.

    10. Fair Value of Financial Instruments

        The Company's financial instruments consist primarily of cash and
    cash equivalents, available-for-sale investments, accounts receivable,
    accounts payable, due to parent company and affiliated companies, and
    long-term obligations. The carrying amounts of these financial
    instruments, with the exception of available-for-sale investments and
    long-term obligations, approximate 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 amounts of the Company's long-term obligations, which
    approximate fair value, were $252,000 and $305,000 at September 27, 1997,
    and September 28, 1996, respectively. The fair value of the Company's
    long-term obligations was determined based on borrowing rates available
    to the Company at the respective year-ends.

    11. Segment Data, Export Sales, and Concentrations of Risk

        The Company's business is divided into three segments. The
    Industrial Refrigeration Systems segment develops, manufactures, markets,

    and rents commercial cooling and industrial refrigeration equipment. The
    Engines segment develops, manufactures, markets, and services gasoline 
                                       20PAGE

    11. Segment Data, Export Sales, and Concentrations of Risk (continued)

    engines for recreational boats, propane and gasoline engines for lift
    trucks, and natural gas engines for vehicular, cooling, pumping,
    refrigeration, and other industrial applications. The Cooling and
    Cogeneration Systems segment develops, manufactures, markets, and
    services natural gas cooling and cogeneration systems, conducts research
    and development on applications of thermal energy, and is developing and
    commercializing a family of gas-powered lighting products.
        Export revenues to Asia accounted for 13%, 7%, and 10% of the
    Company's total revenues in fiscal 1997, 1996, and 1995, respectively.
    Other export revenues accounted for 7%, 6%, and 5% of the Company's total
    revenues in fiscal 1997, 1996, and 1995, respectively. In general, export
    sales are denominated in U.S. dollars.
        The Company purchases engine blocks for its marine and certain other
    engines, as well as engines for certain of its smaller cooling and
    cogeneration products, from one supplier. While the Company believes that
    it has adequate supplies of materials to meet its needs for a three-month
    period, no assurance can be given that the Company will not experience
    shortages of engine blocks in the future that could delay shipments of
    the Company's marine and certain other engines and its cooling and
    cogeneration products.
        Information for fiscal 1997, 1996, and 1995, with respect to the

    paid $2.3 million for shares acquired in fiscal 1997, which are
    classified as long-term available-for-sale investments in the
    accompanying fiscal 1997 balance sheet, and $147.9 million for shares
    acquired from September 28, 1997, through November 19, 1997. The Company
    owned 92% of the outstanding ordinary shares of Peek as of November 19,
    1997. The Company expects to make payments for the remaining ordinary
    shares outstanding during the first quarter of fiscal 1998.
        Pursuant to a promissory note, the Company borrowed $160.0 million
    from Thermo Electron to finance the acquisition of Peek. The promissory
    note is due November 1999, and bears interest at the 90-day Commercial
    Paper Composite Rate plus 25 basis points, set of the beginning of each
    quarter.

    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 Power Corporation and subsidiaries as of September 27, 1997, and
    September 28, 1996, and the results of their operations and their cash
    flows for each of the three years in the period ended September 27, 1997,
    in conformity with generally accepted accounting principles.

    Overview

        The Company's business is divided into three segments: Industrial
    Refrigeration Systems, Engines, and Cooling and Cogeneration Systems.
    Through the Company's FES division, the Industrial Refrigeration Systems
    segment supplies standard and custom-designed industrial refrigeration
    systems used primarily by the food-processing, petrochemical, and
    pharmaceutical industries. NuTemp, Inc. is a supplier of both
    remanufactured and new industrial refrigeration and commercial cooling
    equipment for sale or rental. NuTemp's industrial refrigeration equipment
    is used primarily in the food-processing, petrochemical, and
    pharmaceutical industries, and its commercial cooling equipment is used
    primarily in institutions and commercial buildings, as well as by service
    contractors. The demand for NuTemp's equipment is typically highest in
    the summer period and can be adversely affected by cool summer weather.
        Within the Engines segment, the Company's Crusader Engines division
    manufactures gasoline engines for recreational boats; propane and
    gasoline engines for lift trucks; and natural gas engines for vehicular,
    cooling, pumping, refrigeration, and other industrial applications.
        The Cooling and Cogeneration Systems segment consists of the
    Company's Tecogen division and the Company's ThermoLyte Corporation
    subsidiary. Tecogen designs, develops, markets, and services packaged
    cooling and cogeneration systems fueled principally by natural gas for
    sale to a wide range of commercial, institutional, industrial, and
    multi-unit residential users. Certain large-capacity cooling systems are
    manufactured for Tecogen by FES, and the cogeneration systems are
    manufactured for Tecogen by Crusader. Tecogen also conducts research and
    development of natural gas-engine technology and on applications of
    thermal energy. ThermoLyte is developing and commercializing various
    gas-powered lighting products.
        The Company acquired Peek plc (Peek), a London Stock Exchange-listed
    company, in November 1997. Peek develops, markets, installs, and services
    equipment to monitor and regulate traffic flow in cities and towns around
    the world. Peek offers a wide range of products, including hardware, such
    as loop detectors, traffic signals and controllers, and variable message
    signs, as well as traffic management systems that integrate these
    products to ease roadway congestion, improve safety, and collect data.

                  Financial Condition and Results of Operations

    Overview (continued)

    Traffic management systems include variable message systems to advise
    drivers of accidents and other roadway hazards; traffic signal-timing
    systems that adapt continuously to changing conditions to minimize
    delays; video systems to give real-time analysis of traffic flows at
    intersections and on highways; and automatic toll-collection systems. The
    Company also offers high-resolution video equipment to aid police
    officers in capturing the information necessary to charge individuals
    with motor vehicle violations such as speeding and red light violations.
    Peek had revenues in calendar 1996, excluding revenues from businesses
    sold in 1996 and 1997, of approximately 140 million pounds sterling, or
    approximately $219 million, and profit on ordinary activities after
    taxation, excluding profit from businesses sold in 1996 and 1997, of
    approximately 8 million pound sterling, or approximately $12 million.
    Peek's results of operations in calendar 1996 are unaudited and were
    accounted for in accordance with generally accepted accounting principles
    in the United Kingdom, which differ in certain respects from U.S.
    generally accepted accounting principles. The Company's results of
    operations and financial position for fiscal 1998 are expected to be
    affected significantly by the acquisition of Peek.
        The Company will be required to modify or replace portions of its
    software and the software of Peek so that it will function properly in
    the year 2000. Costs associated with purchasing software which is year
    2000 compliant, excluding costs associated with Peek, is included in
    estimated capital expenditures for fiscal 1998, disclosed in liquidity
    and capital resources. The cost of such new software will be capitalized
    and amortized over the software's useful life, and is not expected to
    have a material effect on the Company's results of operations. The
    Company is in the process of assessing the impact of the year 2000 issue
    on the operations of Peek, including the development of cost estimates
    for, and the extent of any programming changes that might be required to
    address, this issue. At this time, the Company is unable to determine the
    materiality of the year 2000 issue at Peek.

    Results of Operations

    Fiscal 1997 Compared With Fiscal 1996
        Total revenues were $121,046,000 in fiscal 1997 and $120,736,000 in
    fiscal 1996. Industrial Refrigeration Systems segment revenues increased
    to $74,843,000 in 1997 from $73,312,000 in 1996, primarily due to greater
    demand for custom-designed industrial refrigeration packages and product
    services at FES and, to a lesser extent, increased demand for rental
    equipment at NuTemp. These improvements were offset in part by a decrease
    in demand for standard industrial refrigeration packages at FES. Engines
    segment revenues increased to $30,324,000 in 1997 from $28,857,000 in
    1996, primarily due to an increase in lift-truck and TecoDrive(R) engine
    sales, offset in part by a decrease in sales of marine-engine related
    products. The increase in TecoDrive engine sales was principally due to a
    large nonrecurring order of $3.6 million from one customer. Cooling and

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

    Fiscal 1997 Compared With Fiscal 1996 (continued)
    Cogeneration Systems segment revenues were $17,819,000 in 1997, compared
    with $20,477,000 in 1996. Decreased revenues from sponsored research and
    development, gas-fueled cooling systems, and thermoelectric devices were
    offset in part by increased service revenues in 1997.
        The gross profit margin increased to 18% in fiscal 1997 from 17% in
    fiscal 1996. The gross profit margin for the Industrial Refrigeration
    Systems segment increased to 21% in 1997 from 20% in 1996, primarily due
    to higher margins at FES, resulting from lower warranty expenses,
    manufacturing efficiencies, and a decrease in the cost of a major
    component, and higher margins at NuTemp resulting from increased
    revenues. FES experienced a cost increase in the major component in
    fiscal 1996, for which the Company has begun receiving deliveries from an
    additional supplier at a lower cost. The gross profit margin for the
    Engines segment increased to 9% in 1997 from 5% in 1996, primarily due to
    a reduction in warranty expenses and lower overhead expenses resulting
    from the consolidation of two manufacturing facilities at Crusader and,
    to a lesser extent, startup costs in fiscal 1996 associated with the
    introduction of lift-truck engines. The gross profit margin for the
    Cooling and Cogeneration Systems segment decreased to 19% in 1997 from
    22% in 1996, primarily due to lower revenues and higher warranty expenses
    for gas-fueled cooling systems.
        Selling, general, and administrative expenses as a percentage of
    revenues remained unchanged at 14% in fiscal 1997 and 1996. Research and
    development expenses decreased to $2,296,000 in 1997 from $3,214,000 in
    1996, primarily due to lower spending on natural gas-engine products and
    gas-powered lighting products, primarily due to the completion of the
    current phase of development efforts for these products.
        Net gain on sale of investments in fiscal 1996 primarily represents a
    gain of $344,000 relating to the sale of the Company's remaining
    investment in Thermo Electron common stock and a gain of $125,000
    relating to the sale of the Company's remaining investment in
    subordinated convertible debentures issued by Thermo TerraTech Inc., a
    majority-owned subsidiary of Thermo Electron (Note 6). These gains were
    largely offset by a write-down of other investments.
        The effective tax rate was 47% in fiscal 1997 and 48% in fiscal 1996.
    The effective tax rate exceeded the statutory federal income tax rate
    primarily due to an increase in the valuation allowance for net operating
    loss carryforwards and other tax assets of the Company's ThermoLyte
    subsidiary, and the impact of state income taxes.

    Fiscal 1996 Compared With Fiscal 1995
        Total revenues increased 17% to $120,736,000 in fiscal 1996 from
    $103,255,000 in fiscal 1995. Industrial Refrigeration Systems segment
    revenues increased 13% to $73,312,000 in 1996 from $64,708,000 in 1995.
    Revenues at FES increased $7,717,000 in 1996, primarily due to greater
    demand for custom-designed industrial refrigeration packages, offset in
    part by lower sales of standard refrigeration systems. Revenues at NuTemp
    increased $887,000, primarily due to increased demand for remanufactured
    commercial cooling equipment, offset in part by lower demand for rental
    equipment resulting from generally milder summer temperatures in 1996

                  Financial Condition and Results of Operations

    Fiscal 1996 Compared With Fiscal 1995 (continued)
    compared with 1995. Engines segment revenues increased 16% to $28,857,000
    in 1996 from $24,848,000 in 1995, primarily due to the inclusion of
    revenues from lift-truck engines and increased demand for gasoline and
    TecoDrive natural gas engines, offset in part by a decrease of $2,877,000
    in revenues from marine-engine related products. Revenues from
    marine-engine related products declined primarily due to increased
    competition and a decrease in demand. Cooling and Cogeneration Systems
    segment revenues increased 29% to $20,477,000 in 1996 from $15,873,000 in
    1995, primarily due to an increase in revenues from gas-fueled cooling
    systems. Results for the Cooling and Cogeneration Systems segment in 1995
    include a fee of $1,187,000 received from one of the Company's
    distributors of packaged cogeneration systems to satisfy the financial
    obligations under a minimum purchase contract.
        The gross profit margin decreased to 17% in fiscal 1996 from 23% in
    fiscal 1995. The gross profit margin for the Industrial Refrigeration
    Systems segment decreased to 20% in 1996 from 25% in 1995, primarily due
    to lower margins at FES resulting from a change in sales mix. FES' sales
    to the petrochemical industry, which have inherently lower margins,
    increased in 1996 from 1995. To a lesser extent, the gross profit margin
    decreased due to an increase in depreciation expense at NuTemp resulting
    from an increase in rental assets, lower manufacturing efficiencies at
    FES, and higher warranty expenses at NuTemp in 1996 compared with 1995.
    The gross profit margin for the Engines segment decreased to 5% in 1996
    from 11% in 1995, primarily due to unusually high warranty expenses and,
    to a lesser extent, startup costs associated with the introduction of
    lift-truck engines. The gross profit margin for the Cooling and
    Cogeneration Systems segment decreased to 22% in 1996 from 29% in 1995,
    primarily due to the inclusion in 1995 of a fee received from one of the
    Company's distributors of packaged cogeneration systems discussed above.
        Selling, general, and administrative expenses as a percentage of
    revenues decreased to 14% in fiscal 1996 from 15% in fiscal 1995,
    primarily due to an increase in total revenues. Research and development
    expenses were $3,214,000 in fiscal 1996, compared with $3,065,000 in
    fiscal 1995. An increase in research and development expenses for
    gas-fueled lighting products was largely offset by a decrease in spending
    on research and development of natural gas-engine products.
        Interest income decreased to $1,714,000 in fiscal 1996 from
    $1,919,000 in fiscal 1995. Interest income earned on invested proceeds
    from ThermoLyte's March 1995 private placement was more than offset by a
    decrease in interest income earned on the Company's other investments due
    to lower average invested balances. The net gain on sale of investments
    in fiscal 1996 is described in the results of operations for fiscal 1997.
    The net gain on sale of investments in fiscal 1995 primarily represents a
    gain of $768,000 relating to the sale of the Company's investment in
    subordinated convertible debentures issued by Thermedics Inc., a
    majority-owned subsidiary of Thermo Electron (Note 6).
        The effective tax rate was 48% in fiscal 1996, compared with 39% in
    fiscal 1995. These rates exceeded the statutory federal income tax rate
    primarily due to the impact of state income taxes and, in fiscal 1996, a

    valuation allowance established for net operating loss carryforwards and
    other tax assets of the Company's ThermoLyte subsidiary.

    Liquidity and Capital Resources

        Working capital was $54,708,000 at September 27, 1997, compared with
    $57,719,000 at September 28, 1996. Included in working capital are cash,
    cash equivalents, and available-for-sale investments of $28,518,000 at
    September 27, 1997, compared with $35,880,000 at September 28, 1996. Of
    the $28,518,000 balance at September 27, 1997, $15,519,000 was held by
    ThermoLyte and the remainder was held by the Company and its wholly owned
    subsidiaries.
        During fiscal 1997, $2,208,000 of cash was provided by operating
    activities. Cash provided by the Company's operating results was reduced
    by a decrease in accounts payable of $4,383,000, an increase in accounts
    receivable of $3,210,000, and an increase in inventories of $1,247,000.
    These reductions in cash were offset in part by an increase in other
    current liabilities of $3,318,000 and a decrease in unbilled contract
    costs and fees of $2,254,000. The decrease in accounts payable was
    principally due to the timing of purchases of materials for large
    contracts. The increase in accounts receivable was primarily due to the
    timing of billings on percentage-of-completion contracts, reflected in
    the decrease in unbilled contract costs and fees, as well as increased
    shipments at the end of fiscal 1997. Other current liabilities increase
    principally due to an increase in accrued warranty costs and accrued
    income taxes. Inventories increased primarily due to expanded purchases
    of one component prior to its expected redesign by its manufacturer.
        During fiscal 1997, the Company's primary investing activities,
    excluding available-for-sale investment activity, included $5,622,000
    expended for purchases of rental assets and property, plant, and
    equipment and $1,522,000 in proceeds received from the sale of rental
    assets.
        The Company's financing activities used $3,595,000 of cash in fiscal
    1997, primarily due to $3,613,000 of cash expended for the purchase of
    Company common stock. The Company's Board of Directors has authorized the
    repurchase, through March 17, 1998, of up to $5,000,000 of its own
    securities. Any such purchases are funded from working capital. As of
    September 27, 1997, $1,387,000 remained under the Company's
    authorization.
        On November 6, 1997, the Company declared unconditional in all
    respects its cash tender offer for all outstanding ordinary shares of
    Peek. The aggregate cost to acquire all outstanding Peek ordinary shares
    is estimated at approximately $163 million. The Company paid $2.3 million
    for shares acquired in fiscal 1997 and $147.9 million for shares acquired
    from September 28, 1997, through November 19, 1997. The Company owned 92%
    of the outstanding ordinary shares of Peek as of November 19, 1997. The
    Company expects to make payments for the remaining ordinary shares
    outstanding during the first quarter of fiscal 1998. To finance the
    acquisition of Peek, the Company used internal funds and borrowed $160.0
    million from Thermo Electron. (Note 13)

    Liquidity and Capital Resources (continued)

        ThermoLyte's common stock is subject to redemption in December 1998
    or 1999, the redemption value of which is $18,450,000 (Note 1).
        In fiscal 1998, the Company expects to make capital expenditures for
    the purchase of rental assets and property, plant, and equipment of
    approximately $3.5 million, excluding capital expenditures of Peek which
    have yet to be determined by the Company. The Company believes its
    existing resources are sufficient to meet the capital requirements of its
    existing operations for the foreseeable future.

                           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 fiscal 1998 and beyond to
    differ materially from those expressed in any forward-looking statements
    made by, or on behalf of, the Company.

        Ability to Manage Change. The Company has recently experienced
    significant growth in the number of its employees, the demands on its
    operating and financial systems, and the geographic area of its
    operations. In November 1997, the Company acquired Peek plc (Peek), a
    public company in the United Kingdom, which has more than 1,200 employees
    located throughout Europe, Asia, and the United States, and had revenues
    in calendar 1996, excluding revenues of businesses sold in 1996 and 1997,
    of approximately 140 million pounds sterling, or approximately
    $219 million. This acquisition has resulted in new and increased
    responsibilities for the Company's administrative, operational,
    development, and financial personnel. In order to manage the Company's
    changing business, Peek's management and other employees must be
    assimilated into the Company's existing operations. There can be no
    assurance that the Company will be successful in retaining Peek's key
    employees and integrating them into the Company. The Company's success
    depends to a significant extent on the ability of its officers and key
    employees to operate effectively, both independently and as a group, and
    this ability may be impeded by the Company's rapid geographic expansion,
    potential disruption of the Company's business, and diversion of
    management's attention from other business concerns due to the Peek
    acquisition. In addition, there can be no assurance that the Company's
    systems, procedures, and controls will be adequate to support the
    significant expansion of the Company's operations. Any failure of the
    Company's management to manage change effectively could have a material
    adverse effect on the Company's business, financial condition, and
    results of operations. 

         Transition of Product Focus; Dependence on New Products. Since its
    inception, the Company has derived a substantial majority of its revenues
    from development and commercialization of power generation, refrigeration
    and cooling, engines, and related products. While these products are
    expected to continue to generate a significant amount of the Company's
    revenues for the foreseeable future, a substantial portion of the
    Company's revenues is now expected to be derived from the sale of
    electronics and associated hardware and software for the traffic
    industry, as well as from providing integration services for such
    electronics, hardware, and software, through the Company's recently
    acquired Peek subsidiary. A substantial portion of the Company's efforts,
    particularly its product development and marketing efforts, will be
    focused on the traffic market. The Company has had no prior experience in
    the traffic industry, and there can be no assurance that the Company will
    be able to successfully market and sell its newly acquired products and
    services. The Company's future success will depend significantly on its
    ability to develop, introduce, and integrate new products in the traffic

    market and to continue to improve the performance, features, and
    reliability of Peek's current products. In order for Peek to achieve the
    level of profitability desired by the Company, the Company must
    successfully reduce Peek's expenses and improve market penetration. No
    assurance can be given that the Company will be successful in this
    regard. Any failure or inability of the Company's traffic products to
    perform substantially as anticipated or to achieve market acceptance
    would have a material adverse effect on the Company's business, financial
    condition, and results of operations.

         Risks Associated With International Operations. The Company intends
    to continue to expand its presence in international markets. In calendar
    1996, sales originating outside of the United States accounted for
    approximately 70% of the Company's recently acquired Peek subsidiary's
    revenues. 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, if required, 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,
    financial condition, and results of operations.

         Reliance on Sales to Governmental Entities and Custom Contracts. The
    majority of Peek's sales are to governmental entities. Sales to
    governmental entities generally account for approximately 70% of Peek's
    revenues. The Company intends to focus its marketing of Peek's products
    and services on various governmental entities, including the U.S. Federal
    Highway Administration and comparable overseas agencies, regional
    counties of governments, state, and city traffic engineers, public
    transit authorities, public toll operators, law enforcement agencies, and
    tunnel and bridge authorities. Any decrease in purchases by these
    government bodies, including, without limitation, decreases as the result
    of a shift in priorities or overall budgeting limitations, could have an
    adverse effect on the Company's business, financial condition, and
    results of operations. In addition, most of Peek's contracts require the
    development and integration of customized products for a fixed fee.
    Contracts with governmental entities often permit the purchaser to cancel
    the agreement at any time. A significant overrun in Peek's expenses or
    cancellation of a significant contract could also result in a material
    adverse effect on the Company's business, financial condition, and
    results of operations.

        Competition. The Company encounters and expects to continue to
    encounter intense competition in the sale of its products. Although the
    Company has a proprietary position with respect to certain features of
    its products, the core technologies relating to its cooling and
    cogeneration products are mature and available to other companies. A
    number of companies, including companies with greater financial resources
    than those of the Company, offer products that compete with those offered
    by the Company, and there can be no assurance that other companies will
    not develop competitive products. In addition, electric utility pricing
    programs provide competition for the Company's cooling and cogeneration
    products.
         The market for traffic products and services is extremely
    competitive, and the Company expects that competition will continue to
    increase. The Company believes that the principal competitive factors in
    the traffic industry are price, functionality, reliability, service and
    support, and vendor and product reputation. The Company believes that its
    ability to compete successfully will depend on a number of factors both
    within and outside its control, including the pricing policies of its
    competitors and suppliers, the timing and quality of products introduced
    by the Company and others, the Company's ability to maintain a strong
    reputation in the traffic industry, and industry and general economic
    trends. In the traffic market, the Company currently competes with
    companies with greater financial resources and name recognition. The
    introduction by one of these competitors or a new competitor of a
    technologically superior product would have a material adverse effect on
    the Company's business, financial condition, and results of operations.
    There can be no assurance that the Company will be able to compete
    successfully with existing or new competitors.
        The Company's sale of industrial refrigeration systems is subject to
    intense competition. The industrial refrigeration market is mature,
    highly fragmented, and extremely dependent on close customer contacts.
        Competition in the compressed natural gas (CNG) vehicle and
    alternative-fuel engine markets is intense, and current and potential
    competitors in some or all segments of these markets include major
    automotive and natural gas companies and other companies that have
    greater financial resources than the Company. If the CNG vehicle business
    is to succeed, natural gas will need to be economically attractive
    compared with other alternative fuels, such as ethanol and methanol, and
    compared with improved gasoline formulas.
        Several companies offer marine engines that compete with those
    manufactured by Crusader. In addition, in recent years, certain large
    manufacturers of marine engines have vertically integrated their
    respective businesses by acquiring boat manufacturers that previously had
    been independent purchasers of engines from Crusader and other engine
    manufacturers. The number of potential buyers of Crusader's engines has
    decreased accordingly.

        Dependence of Markets on Government Regulation. The natural gas
    vehicle market is in its formative stage. The use of CNG engines in
    vehicles in the United States results primarily from governmental
    regulations mandating or encouraging the use of alternative fuels. The
    Company's CNG engine business is subject to the demand driven by various

    provisions of the 1990 Clean Air Act, as well as energy and environmental
    legislation that has been or may be enacted at state and local levels,
    which may be more stringent than federal laws. Natural gas is one of many
    alternative fuels that are addressed by the regulations. Others include
    methanol, ethanol, propane, hydrogen, electricity, and reformulated
    gasoline. There can be no assurance that natural gas will become a
    preferred alternative fuel for vehicles or that existing and future
    regulations or their enforcement will create material long-term demand
    for natural gas-powered vehicles.
        The Public Utility Regulatory Policies Act of 1978 (PURPA) and state
    laws and regulations implementing PURPA prohibit discrimination by
    electric utilities against cogeneration providers and require utilities
    to purchase co-generated electricity under certain conditions. Under
    these regulations, certain classes of facilities are exempt from the
    provisions of the Public Utility Holding Company Act, as well as many
    state laws and regulations regarding the setting of electricity rates and
    the financial and organizational regulation of electric utilities, and
    certain provisions of the Federal Power Act. Because the Company's
    current customers typically do not sell power to electric utilities, the
    Company does not rely to a significant extent on the provisions of PURPA
    that require utilities to purchase electricity from cogeneration
    providers. However, recent bills in Congress have proposed amendments to,
    and in some cases, the repeal of, certain of these laws or regulations.
    Any such amendment or repeal could have a material adverse effect on the
    Company's cogeneration business.
        The Intermodal Surface Transportation Efficiency Act (ISTEA) provides
    significant funding in the United States for intermodal surface
    transportation and advanced traffic management systems. The ISTEA has
    been extended until March 31, 1998. The failure to further extend or
    reauthorize ISTEA could have a material adverse effect on demand for the
    Company's traffic products in the United States. 

        Importance of Energy Prices. The cost savings that result from use of
    the Company's packaged cooling and cogeneration systems are directly
    related to the retail price of electricity. In the past several years,
    electricity prices have declined in many areas and rates remain
    relatively low on a historical basis in many regions. Given prevailing
    rate structures, demand for the Company's cooling and cogeneration
    systems has been less than anticipated. Although the Company believes
    that increases in demand, as well as potential increases in the cost of
    fuel, will lead to eventual increases in electricity rates, there can be
    no assurance that electricity prices will increase in the future. The
    economic benefits of the Company's natural gas engine products and
    packaged cooling and cogeneration systems are also affected by the cost
    of natural gas. A significant increase in the relative cost of natural
    gas could also have a material adverse effect on the sale of certain of
    the Company's products.

        Incentives for Cooling Systems. Purchasers of the Company's
    Tecochill(R) cooling systems often receive investment incentives for the
    purchase of Tecochill equipment from gas utilities or state or municipal
    governments. Although the Company has no reason to believe these

                                       34PAGE

    Thermo Power Corporation                        1997 Financial Statements

                           Forward-looking Statements

    incentives will be discontinued, elimination of these incentives could
    have a material adverse effect on sales of the Company's Tecochill
    systems.

        Risks Associated with Protection, Defense, and Use of Intellectual
    Property and Ownership of Technology Rights. The Company holds several
    patents relating to various aspects of its products. Proprietary rights
    relating to the Company's products are protected from unauthorized use by
    third parties only to the extent that they are covered by valid and
    enforceable patents or are maintained in confidence as trade secrets.
    There can be no assurance that patents will be issued 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 and, in the absence of patent
    protection, the Company may be vulnerable to competitors who attempt to
    copy the Company's products or gain access to its trade secrets and
    know-how. Proceedings initiated by the Company to protect its proprietary
    rights could result in substantial costs to the Company. There can be no
    assurance that competitors of the Company will not initiate litigation to
    challenge the validity of the Company's patents, or that they will not
    use their resources to design comparable products that do not infringe
    the Company's patents. There may also be pending or issued patents held
    by parties not affiliated with the Company that relate to the Company's
    products or technologies. The Company may need to acquire licenses to, or
    contest the validity of, any such patents. There can be no assurance that
    any license required under any such patent would be made available on
    acceptable terms or that the Company would prevail in any such contest.
    The Company could incur substantial costs in defending itself in suits
    brought against it or in suits in which the Company may assert its patent
    rights against others. If the outcome of any such litigation is
    unfavorable to the Company, the Company's business and results of
    operations could be materially adversely affected. In addition, 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.
        In addition, a significant percentage of the Company's research and
    development is sponsored by third parties. Sponsors of these programs
    generally own the rights to technology that is developed as a result of
    the Company's work under the programs. These rights could limit the
    Company's ability to commercialize any technological breakthroughs made
    in the course of such work.

        No Assurance of Development and Commercialization of ThermoLyte
    Products; Uncertain Market Acceptance; Potential Product Liability. The
    Company's ThermoLyte subsidiary is developing and commercializing
    propane-fueled lighting products. Product development involves a high
    degree of risk, and returns to investors are dependent upon successful
    development and commercialization of the ThermoLyte products. There can

    be no assurance that the Company will be able to build the sales and
    marketing organization necessary for the successful commercialization of
    its products. In addition, as with any new technology, there is
    substantial risk that the marketplace may not accept or be receptive to
    the potential benefits of such technology. Market acceptance of the
    Company's proposed products will depend, in large part, upon the ability
    of the Company to demonstrate the safety of such products and their
    advantages over commercially available alternatives. There can be no
    assurance that the ThermoLyte products will be accepted by the public.
    Finally, because the ThermoLyte products will be powered by propane or a
    similar fuel that is combustible, the Company may be subject to potential
    product liability damages. The Company intends to design the ThermoLyte
    products to minimize these effects and believes that it will be able to
    obtain insurance against such liabilities on terms acceptable to the
    Company. However, no assurance can be given that damages from product
    liability will not have a material adverse impact on the results of
    operations, financial condition, or reputation of the Company.
