                   Notes to Consolidated Financial Statements

    1.  General

        The interim consolidated financial statements have been prepared by
    Thermo Power Corporation (the Company) without audit and, in the opinion
    of management, reflect all adjustments of a normal recurring nature
    necessary for a fair statement of the financial position at March 29,
    1997, the results of operations for the three- and six-month periods
    ended March 29, 1997, and March 30, 1996, and the cash flows for the
    six-month periods ended March 29, 1997, and March 30, 1996. Interim
    results are not necessarily indicative of results for a full year.

        The consolidated balance sheet presented as of September 28, 1996,
    has been derived from the consolidated financial statements that have
    been audited by the Company's independent public accountants. The
    consolidated financial statements and notes are presented as permitted by
    Form 10-Q and do not contain certain information included in the annual
    financial statements and notes of the Company. The consolidated financial
    statements and notes included herein should be read in conjunction with
    the financial statements and notes included in the Company's Annual
    Report on Form 10-K for the fiscal year ended September 28, 1996, filed
    with the Securities and Exchange Commission.


    Item 2 - 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 under the caption "Forward-looking Statements"
    in Exhibit 13 to the Company's Annual Report on Form 10-K for the fiscal
    year ended September 28, 1996, filed with the Securities and Exchange
    Commission.

    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. (NuTemp) is a supplier of both
    remanufactured and new industrial refrigeration and commercial cooling
    equipment for sale or rental. NuTemp's industrial refrigeration equipment

                                        7PAGE

                            THERMO POWER CORPORATION

    Overview (continued)

    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 months. Cool summer weather can adversely affect the Company's
    NuTemp business because the Company's cooling systems are used primarily
    to reduce temperatures below ambient air temperatures.

        Within the Engines segment, the Company's Crusader Engines division
    (Crusader) 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
    (ThermoLyte) subsidiary, formed in March 1995. 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 by FES, and the
    cogeneration systems are manufactured by Crusader. Tecogen also conducts
    research and development of natural gas-engine technology and on
    applications of thermal energy. ThermoLyte is developing and
    commercializing a family of gas-powered lighting products.

        The Company's revenues by industry segment are shown in the following

    Results of Operations

    Second Quarter Fiscal 1997 Compared With Second Quarter Fiscal 1996

        Total revenues were $28,825,000 in the second quarter of fiscal 1997
    and $29,756,000 in the second quarter of fiscal 1996. Industrial
    Refrigeration Systems segment revenues decreased to $15,639,000 in 1997
    from $15,962,000 in 1996, primarily due to lower demand for rental
    equipment and decreased shipments of remanufactured commercial cooling
    equipment at NuTemp. Engines segment revenues decreased 5% to $7,916,000
    in 1997 from $8,304,000 in 1996, primarily due to the inclusion in 1996
    of a large shipment of TecoDrive(R) natural gas engines to one customer,
    offset in part by an increase in lift truck engine sales. Cooling and
    Cogeneration Systems segment revenues were relatively unchanged at
    $5,948,000 in 1997, compared with $5,913,000 in 1996. Increased revenues
    from gas-fueled cooling systems and product services were offset in part
    by decreased revenues from sponsored research and development and the
    inclusion of a large shipment of thermoelectric devices in 1996. The
    decrease in sponsored research and development resulted from a reduction
    in funding. The Company expects that revenues from sponsored research and
    development will continue to decrease as compared with revenues recorded
    in fiscal 1996.

        The gross profit margin increased to 19% in the second quarter of
    fiscal 1997 from 16% in the second quarter of fiscal 1996. The gross
    profit margin for the Industrial Refrigeration Systems segment increased
    to 21% in 1997 from 17% in 1996, primarily due to higher margins at FES
    resulting from lower warranty expenses and manufacturing efficiencies,
    and higher margins at NuTemp due to the inclusion in 1996 of lower-margin
    revenues from two large contracts. The Company experienced a cost
    increase in one of the major components of its industrial refrigeration
    packages in fiscal 1996, for which the Company has identified an
    additional supplier at a lower cost. Margins within this segment were
    favorably affected by the resulting lower costs for this component in the
    second quarter of fiscal 1997. The gross profit margin for the Engines
    segment increased to 10% in 1997 from 3% in 1996, primarily due to a
    reduction in warranty expenses and to lower overhead expenses resulting
    from the consolidation of two manufacturing facilities at Crusader. The
    gross profit margin for the Cooling and Cogeneration Systems segment
    decreased to 20% in 1997 from 28% in 1996, primarily due to a decrease in
    revenues from thermoelectric devices that have relatively higher margins
    and from the shipment in 1996 of two packaged cogeneration systems with
    substantially higher margins.

        Selling, general, and administrative expenses as a percentage of
    revenues increased to 15% in the second quarter of fiscal 1997 from 14%
    in the second quarter of fiscal 1996 principally due to higher sales
    commissions at FES. Research and development expenses decreased to
    $627,000 in 1997 from $791,000 in 1996, primarily due to a decrease in
    spending on natural gas-engine products and gas-powered lighting
    products, primarily due to the completion of development efforts for
    these products.

                            THERMO POWER CORPORATION

    Second Quarter Fiscal 1997 Compared With Second Quarter Fiscal 1996
    (continued)

        Gain on sale of investments in the second quarter of fiscal 1996
    represents a gain relating to the sale of the Company's remaining
    investment in 6.5% subordinated convertible debentures issued by Thermo
    TerraTech Inc., a majority-owned subsidiary of Thermo Electron
    Corporation.
        The effective tax rate was 50% in the second quarter of fiscal 1997
    and 38% in the second quarter of fiscal 1996. The effective tax rate
    exceeded the statutory federal income tax rate, primarily due to an
    increase in 1997 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 in fiscal 1997 and 1996.

    First Six Months Fiscal 1997 Compared With First Six Months Fiscal 1996

        Total revenues were $57,611,000 in the first six months of fiscal
    1997 and $57,208,000 in the first six months of fiscal 1996. Industrial
    Refrigeration Systems segment revenues increased 5% to $34,785,000 in
    1997 from $33,033,000 in 1996, primarily due to greater demand for
    custom-designed industrial refrigeration packages and product services at
    FES. Engines segment revenues decreased 14% to $13,323,000 in 1997 from
    $15,557,000 in 1996, primarily due to the inclusion in 1996 of a large
    shipment of TecoDrive(R) natural gas engines to one customer and a
    decrease in marine-engine related products, offset in part by an increase
    in lift-truck engine sales. Revenues from marine-engine related products
    declined primarily due to increased competition and a decrease in demand.
    These trends are expected to continue. Cooling and Cogeneration Systems
    segment revenues increased 11% to $10,564,000 in 1997 from $9,523,000 in
    1996. Increased revenues from gas-fueled cooling systems and product
    services were offset in part by decreased revenues from sponsored
    research and development, packaged cogeneration systems, and
    thermoelectric devices.

        The gross profit margin was unchanged at 17% in the first six months
    of fiscal 1997 and 1996. The gross profit margin for the Industrial
    Refrigeration Systems segment was unchanged at 19% in 1997 and 1996.
    Improved margins at FES resulting from lower warranty expenses and
    improved manufacturing efficiencies were offset by lower margins at
    NuTemp resulting primarily from a decrease in rental revenues. The gross
    profit margin for the Engines segment increased to 7% in 1997 from 4% in
    1996, primarily due to a reduction in warranty expenses and to lower
    overhead expenses resulting from the consolidation of two manufacturing
    facilities at Crusader. The gross profit margin for the Cooling and
    Cogeneration Systems segment decreased to 20% in 1997 from 27% in 1996,
    primarily due to the reasons discussed in the results of operations for
    the second quarter.
        Selling, general, and administrative expenses as a percentage of
    revenues remained unchanged at 14% in the first six months of fiscal 1997
    and 1996. Research and development expenses decreased to $1,271,000 in
    1997 from $1,529,000 in 1996. An increase in spending on gas-powered
    lighting products was more than offset by a decrease in spending on
    natural gas-engine products.

    First Six Months Fiscal 1997 Compared With First Six Months Fiscal 1996
    (continued)

        Net gain on sale of investments in the first six months of 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
    6.5% subordinated convertible debentures issued by Thermo TerraTech Inc.,
    a majority-owned subsidiary of Thermo Electron.

        The effective tax rate was 55% in the first six months of fiscal 1997
    and 38% in the first six months of fiscal 1996. The effective tax rate
    exceeded the statutory federal income tax rate for the reasons discussed
    in the results of operations for the second quarter.

    Liquidity and Capital Resources

        Consolidated working capital was $56,411,000 at March 29, 1997,
    compared with $57,719,000 at September 28, 1996. Included in working
    capital are cash, cash equivalents, and available-for-sale investments of
    $36,768,000 at March 29, 1997, compared with $35,880,000 at September 28,
    1996. Of the $36,768,000 balance at March 29, 1997, $15,912,000 was held
    by ThermoLyte and the remainder was held by the Company and its wholly
    owned subsidiaries. 

        During the first six months of fiscal 1997, $4,040,000 of cash was
    provided by operating activities. Cash provided by operating results was
    increased by a reduction in inventories of $2,143,000, primarily due to
    reduced stock levels resulting from a reduction in lead time by a
    supplier, offset in part by an increase in accounts receivable of
    $1,149,000, resulting principally from the timing of cash collections.

        During the first six months of fiscal 1997, the Company's primary
    investing activities, excluding sale and maturities of available-for-sale
    investments, included capital expenditures and the sale of rental assets.
    During the first six months of fiscal 1997, the Company expended
    $2,078,000 for purchases of rental assets and property, plant, and
    equipment and recorded $944,000 in proceeds from the sale of rental
    assets. 

        The Company's financing activities used $1,990,000 of cash in the
    first six months of fiscal 1997, primarily due to $2,034,000 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 would be funded from
    working capital. Through March 29, 1997, the Company has expended
    $2,034,000 under this authorization.

        During the remainder of fiscal 1997, the Company expects to make
    capital expenditures of approximately $2,000,000. The Company believes
    its existing resources are sufficient to meet the capital requirements of
    its existing operations for the foreseeable future.
