    Item 1. Business

    (a)  General Development of Business

         Thermo Power Corporation (the Company or the Registrant) develops
    and commercializes environmentally sound and economically efficient power
    generation, cooling, lighting, and related products. The Company's
    business is divided into three segments. The Industrial Refrigeration
    Systems segment develops, manufactures, markets, and services industrial
    refrigeration and commercial cooling equipment, and also rents commercial
    cooling and industrial refrigeration equipment. The Engines segment
    develops, manufactures, markets, and services gasoline engines for
    recreational boats, propane and gasoline engines for lift trucks, and
    natural gas engines for fleet vehicles and industrial applications. The
    Cooling and Cogeneration Systems segment develops, manufactures, markets,
    and services natural gas cooling and cogeneration systems, and conducts
    research and development on applications of thermal energy. Through its
    78%-owned ThermoLyte Corporation (ThermoLyte) subsidiary, formed in March
    1995, the Company is developing and commercializing a family of
    gas-powered lighting products, including area lights, flashlights,
    emergency lights, and other lighting products.

         The ThermoLyte family of lighting products is based on the
    Company's patented technology for a rigid mantle, the "bulb" in gas
    lights. This durable mantle allows the Company to design products that
    are portable and use propane as a power source instead of batteries.
    Using propane offers several advantages over batteries, including a
    potentially infinite shelf life, substantially longer operating hours,
    constant brightness, and no battery disposal.

         ThermoLyte has developed and is now preparing to introduce a
    propane-powered area light to the marketplace. In preparation for
    introduction of the area light, ThermoLyte conducted focus groups to
    gauge consumer reaction to the light's concept, performance, and design.
    The final design is a decorative, contemporary-style area light suitable
    for providing an alternative to candles, oil lamps, or battery-powered
    lights in the home or backyard. Late in calendar 1996, the Company plans
    to make a limited initial market introduction of its area light through a
    catalog for employees and shareholders of Thermo Electron Corporation
    (Thermo Electron) and its subsidiaries. The Company is also engaged in
    qualifying vendors for manufacturing and consulting specialty catalog
    buyers. 

         During the first quarter of fiscal 1996*, the Company acquired the
    thermoelectric cooling module business from ThermoTrex Corporation
    (ThermoTrex), a majority-owned subsidiary of Thermo Electron, for
    $860,000, which was the net book value of the business acquired. The
    Company's thermoelectric cooling modules are used to control the


    * References to fiscal 1996, 1995, and 1994 herein are for the fiscal
     years ended September 28, 1996, September 30, 1995, and October 1,

    temperature of laser diodes in fiber-optic telecommunication equipment
    and biomedical instruments, as well as thermal reference sources (TRSs),
    which are used for calibrating infrared imaging systems. The Company is
    also researching other potential applications for this technology.

         The Company was originally incorporated in Massachusetts in June
    1985 under the name Tecogen Inc., as a wholly owned subsidiary of Thermo
    Electron to succeed the business of Thermo Electron's Thermal Products
    Division. In March 1993, the Company's name was changed to Thermo Power
    Corporation. As of September 28, 1996, Thermo Electron owned 7,915,306
    shares of the Company's common stock, representing 63% of such stock
    outstanding at that time. Thermo Electron is a world leader in
    environmental monitoring and analysis instruments, biomedical products
    such as heart-assist devices and mammography systems, papermaking and
    paper-recycling equipment, biomass electric power generation, and other
    specialized products and technologies. Thermo Electron also provides a
    range of services related to environmental quality. During fiscal 1996,
    Thermo Electron purchased 86,700 shares of the Company's common stock in
    the open market at a total price of $1,165,000.

    Forward-looking Statements

         Forward-looking statements within the meaning of Section 21E of the
    Securities Exchange Act of 1934, are made throughout this Annual Report
    on Form 10-K. These statements involve a number of risks and
    uncertainties, including those detailed under the caption "Forward-
    looking Statements" in the Registrant's Fiscal 1996 Annual Report to
    Shareholders incorporated herein by reference.

    (b)  Financial Information About Industry Segments

         The Company's business is divided into three segments. The
    Industrial Refrigeration Systems segment develops, manufactures, markets,
    and services industrial refrigeration and commercial cooling equipment,  
    and rents commercial cooling and industrial refrigeration equipment. The
    Engines segment develops, manufactures, markets, and services gasoline

    (c)  Description of Business

         (i)  Principal Products and Services

    Industrial Refrigeration Systems

         Industrial Refrigeration Packages. The Company's FES division
    designs, engineers, manufactures, and services industrial refrigeration
    equipment used for cooling, freezing, and cold-storage applications in
    the food-processing, petrochemical, pharmaceutical, and liquefied-gas
    storage industries. FES produces complete industrial refrigeration
    systems, and it also supplies components for use in industrial
    refrigeration systems produced by others. 

         FES equipment for food and beverage customers is primarily standard
    products, such as screw-compressor packages, liquid-refrigerant pump
    packages, state-of-the-art control systems, and ASME (American Society of
    Mechanical Engineers) pressure vessels. A screw-compressor package, which
    consists of a screw compressor, an electric-drive motor, an oil
    separator, a control panel, and piping and tubing, constitutes the
    majority of this equipment. FES also provides screw-compressor packages
    powered by the Company's natural gas TecoDrive(R) engines. These packages
    are pre-engineered and are manufactured in quantity. Examples of
    applications of industrial refrigeration equipment used by food and
    beverage processors include the freezing, storing, and warehousing of
    meats, fish, fruits, and vegetables; freezing of fruit juice
    concentrates; or controlling process temperatures in brewing and
    wine-making, and soft drink carbonization, where the temperature of water
    is regulated to absorb a controlled quantity of carbon dioxide. In
    addition, FES manufactures screw-compressor packages used to cool inlet
    air for gas turbine generators at utilities.

         FES supplies entire refrigeration packages to petrochemical,
    pharmaceutical, and related industries for integration into their plants'
    refrigeration systems. These higher-cost custom packages require
    significant design engineering and are used in a wide variety of
    applications, such as chilling brine that cools chemicals used in the
    production of penicillin. In another application of a custom package, FES
    units are used to chill and condense toxic effluent gases normally
    released to flare.

         FES systems have capacities ranging from 10 to 4,500 tons, with
    evaporating temperatures ranging from +50.F to -100.F. Approximately 65%
    of FES's sales are of standard units for the food and beverage industry,
    and approximately 35% are of custom units for the petrochemical and
    pharmaceutical industries. The average price for a standard food and
    beverage refrigeration package is approximately $50,000, and a
    representative price for a custom unit would be approximately $300,000,
    although prices for these units can exceed $1 million. FES refrigeration
    packages can be designed for use with any common refrigerant, but
    approximately 80% of FES's units operate on ammonia. FES's utilization of
    ammonia, a cost-effective and environmentally safe substance compared
    with conventional chlorofluorocarbon (CFC)-based refrigerants, places FES
    in a leadership position to target the reduction of CFC systems. The

                                        4PAGE

    production of CFCs was phased out in January 1996. Ammonia does not harm
    the ozone layer, costs much less than conventional refrigerants, and is
    widely available on a global basis.

         In 1994, FES introduced a screw-compressor package powered by a gas
    engine. Powering refrigeration systems with a gas engine instead of
    electricity allows FES to offer its customers in areas with high
    electricity rates a more cost-effective cooling system. Many of these
    systems incorporate one of the Company's TecoDrive natural gas engines.

         The Company's NuTemp subsidiary serves the industrial refrigeration
    and commercial cooling markets. NuTemp buys new and surplus refrigeration
    equipment that it remanufactures for sale or rental. NuTemp serves
    numerous markets for its industrial refrigeration equipment, including
    the food-processing, petrochemical, and pharmaceutical industries. NuTemp
    provides commercial cooling equipment to large institutions, commercial
    building owners, and service contractors across the country. Ongoing
    retrofit programs to replace CFC-based equipment continue to provide a
    temporary rental business for NuTemp. One of NuTemp's key services is
    responding to emergency cooling situations by providing
    large-tonnage-capacity refrigeration equipment on short notice.

         In 1996, NuTemp introduced its NT-Series water- and air-cooled
    industrial cooling systems. NuTemp continues to custom-design industrial
    refrigeration to meet customers' specific requirements, including
    capacity, operating-temperature, and control-system needs. NuTemp
    manufactures custom systems using both new and remanufactured components
    to provide a cost-effective and timely solution for its customers. Custom
    systems are offered for rental with an option to buy, providing a unique
    service in this market.

         Applications for NuTemp's products range from cooling water to
    +60.F to cooling synthetic fluids to -60.F. The colder fluids are used in
    industrial process applications, which include chemical-reaction control,
    environmental testing, VOC (volatile organic compound) recovery, and
    plastics production.

         Revenues from industrial refrigeration packages were $66,565,000,
    $55,193,000, and $53,146,000 in fiscal 1996, 1995, and 1994,
    respectively.

         Microprocessor Controls. FES microprocessor-based control systems
    for industrial refrigeration equipment are designed to reduce energy
    consumption through operating efficiencies, to anticipate problems with
    built-in pre-alarms, to announce system shutdowns, to offer memory
    storage, and to provide easy sensor calibration through keypads and
    displays. These controls are supplied with FES products, and they can
    also be fitted on refrigeration packages produced by other suppliers for
    ease of integration within FES's central supervisory control system. 

         Other Products. FES also manufactures and sells liquid-refrigerant
    recirculation systems, heat-recovery heat exchangers, and pressure
    vessels for use in refrigeration packages and systems produced by others.

                                        5PAGE

    FES's liquid-refrigerant recirculation systems, or "pump packages," are
    used in a variety of applications such as food freezing and storage,
    industrial process cooling, and thermal storage systems.

         NuTemp also buys new and surplus commercial cooling equipment which
    is remanufactured for sale or rental. NuTemp's customers in the
    commercial cooling industry include institutions, commercial building
    owners, and service contractors. The commercial cooling industry is
    currently coming into compliance with the Montreal Protocol which
    prohibits the production of CFC refrigerants effective January 1996. This
    retrofit process is creating an increase in the rental market for
    NuTemp's commercial cooling systems, which operate on alternative
    refrigerants, while customers install new equipment.

    Engines

         Marine Engines. The Company's Crusader Engines division (Crusader)
    manufactures, markets, and services inboard marine engines and
    accessories both to OEM (original equipment manufacturer) boat companies
    and to a network of 35 distributors who support 400 dealers servicing
    Crusader's products in the field. Crusader does not customarily
    manufacture engines for its own inventory, but rather in response to
    orders from distributors, dealers, and boat manufacturers. Crusader's key
    customers are OEM manufacturers of "cruiser" class boats generally
    ranging in size from 25 to 45 feet. The purchase price of boats
    containing Crusader engines typically is in the $50,000 to $250,000
    range. Sales of engines to OEM customers account for approximately 86% of
    Crusader's unit sales. In fiscal 1996, sales to Crusader's top three OEM
    customers accounted for approximately 35% of Crusader's unit sales. 

         Revenues from marine engines were $18,659,000, $21,536,000, and
    $18,315,000 in fiscal 1996, 1995, and 1994, respectively.

         TecoDrive Natural Gas Engines for Vehicles. The Company's extensive
    development work on dedicated compressed natural gas (CNG) engines has
    resulted in sales of a number of its TecoDrive engines for use in school
    buses, package-delivery vehicles, and other fleet vehicles. These engines
    feature substantially lower emissions than currently commercially
    available gasoline or natural gas engines. In November 1995, the
    Company's TecoDrive 4300 engine became the first heavy-duty natural gas
    engine to be certified for Ultra Low-Emission Vehicles (ULEVs) by the
    U.S. Environmental Protection Agency (EPA). This certification broadens
    the market for the Company's TecoDrive 4300 engines to include states
    with the strictest emissions standards.

         The Company has entered into a contract with the U.S. Department of
    Energy to develop, emission-certify, and build a prototype 5.7-liter
    TecoDrive engine. The Company expects that the prototype engine will be
    emission-certified by mid-1997. In addition, the U.S. Postal Service has
    ordered four of such prototype engines, subject to emission
    certification, for use in mobile post office units in the New York City
    vicinity.


                                        6PAGE

         The natural gas vehicle (NGV) market is still in a formative stage.
    The use of NGVs in the United States results primarily from governmental
    regulations and incentive programs requiring the use of alternative fuels
    in certain situations. The Clean Air Act Amendments of 1990 and the
    Energy Policy Act of 1992, as well as numerous state regulations, require
    the increased use of alternative fuels over a period of time. There can
    be no assurance that NGVs will be the most popular alternative-fuel
    vehicles under the various mandates. The Company believes that many NGVs
    currently in use do not comply with regulations in the United States, the
    wide majority being equipped with aftermarket gasoline-to-natural-gas
    conversion kits that do not provide the low emissions offered by the
    Company's factory-built dedicated engines. Producing a natural gas engine
    with reduced emissions and adequate power at a cost that is not
    prohibitive is a key factor in the development of the market.

         TecoDrive Natural Gas Engines for Irrigation and Industrial
    Applications. The Company manufactures natural gas engines for the
    irrigation pump engine market. The Company is the first supplier to offer
    agricultural users extended warranties and total service support similar
    to that offered to the Company's marine engine, cooling, and cogeneration
    customers. As a result of the positive response the Company has received
    from its customers in the irrigation market, the Company has developed
    TecoDrive engines for other stationary applications, such as powering air
    and gas compressors. There are now four OEM manufacturers incorporating
    the Company's TecoDrive engines into their natural gas compressors for
    NGV refueling. In fiscal 1996, the Company received orders for a total of
    90 engines for pipeline gas compressors in Western Canadian gas fields.
    The Company also provides engines for stationary applications for
    Climaveneta, a manufacturing firm in Italy, S.A.T. Trading Company in the
    United Arab Emirates, and Paramo in Columbia. In addition, the Company
    offers a range of optional equipment that broadens the industrial
    applications for its engines.

         Propane and Gasoline Engines for Lift Trucks. The Company has
    embarked on a significant program to engineer and manufacture 2.2-, 3.0-,
    and 4.3-liter propane and gasoline engines for installation into lift
    trucks. The Company is also developing 5.7- and 7.4-liter engines for
    lift trucks. Currently, the Company is shipping approximately 100 engines
    per month to Clark Materials Handling Company, one of the largest
    suppliers of lift trucks in the United States. The Company is also
    shipping approximately 120 3.0-liter engines per month to Toyota
    Industrial Equipment Manufacturing Inc. (Toyota) for installation into
    Toyota's lift trucks. In fiscal 1996, the Company received an order from
    Daewoo for 600 engines, and it is also engineering lift-truck engines for
    Royal Tractor Company, Taylor Machines Works, Inc., and Hoist Lift-truck
    MSG., Inc.

    Cooling and Cogeneration Systems

         The Company designs, develops, manufactures, 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. Many of these products are powered by
    the Company's dedicated TecoDrive natural gas engines.

                                        7PAGE

         The Company's Tecochill commercial cooling and Tecogen(R)
    cogeneration products incorporate several proprietary features that are
    the result of the Company's advances in engine, thermal, and control
    technologies. One such proprietary feature is the Company's
    microprocessor-based control module, which automates the operation of
    such systems and can also include remote control, monitoring, and
    diagnostic capabilities. The standardized designs of the Company's
    products also enable rapid installation and startup, facilitate
    maintenance, and allow competitive delivery time. The Company supports
    its customers by offering a comprehensive maintenance contract under
    which the Company assumes responsibility for substantially all
    maintenance, repairs, and replacement parts.

         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 few years, electricity prices have declined
    in many areas and rates remain relatively low on a historical basis in
    most regions. Given prevailing rate structures, demand for the Company's
    cooling and cogeneration systems has been less than anticipated.

         Tecochill Cooling Systems. The Company entered the gas-fueled
    cooling business by introducing its 150-ton gas-fueled cooling unit in
    1988. The Company's Tecochill units are powered by the same TecoDrive
    engine used in the Company's small-scale cogeneration systems. Tecochill
    products are equipped with microprocessor controls allowing fully
    automated, unattended operation. Tecochill units can be programmed to run
    at different speeds to follow variable cooling loads for greater
    efficiency than conventional electric motor-driven air conditioners that
    run at a constant speed. These units are self-contained packages that are
    delivered to customer sites as finished products for standard
    installation. Tecochill units can be fitted with optional heat-recovery
    packages yielding hot water. The Company has sold approximately 350 of
    its Tecochill units to date, which are operating in 26 states and four
    foreign countries. The Company is currently offering additional
    gas-fueled air conditioning equipment, ranging in size from 50 to 1,000
    tons, for use in multi-unit residential buildings, nursing homes,
    hospitals, and similar institutions. Although the purchase price of the
    Company's Tecochill units is approximately 100-200% higher than that of
    electric motor-driven air conditioners of comparable sizes, lower
    operating costs associated with the use of Tecochill units generally lead
    to payback of the incremental capital cost in approximately four years.
    The average expected useful life of a Tecochill unit is comparable to
    that of an electric motor-driven air conditioner, typically 15 years.

         Revenues from cooling systems were $9,135,000, $4,956,000, and
    $3,772,000 in fiscal 1996, 1995, and 1994, respectively.

         Tecogen Cogeneration Systems. In 1983, the Company introduced its
    first Tecogen packaged cogeneration system, the 60-kilowatt (kW) CM-60
    model powered by the Company's TecoDrive engine. Approximately 600 CM-60
    and CM-75 units have been installed at approximately 350 sites across the
    United States. These systems are automated, self-contained cogeneration
    packages that are delivered as finished units to customer sites. In
    general, these systems are manufactured to standard designs and are
    assembled and tested on a production-line basis. The Company's

                                        8PAGE

    cogeneration systems use a single fuel source, natural gas, to
    simultaneously produce electricity and thermal energy in the form of hot
    water. By using energy that would otherwise be wasted, the Company's
    cogeneration systems operate at a cost that can be comparable to the cost
    of producing hot water alone in conventional systems. The electricity
    produced is used principally to meet on-site energy requirements and
    replaces electricity that would otherwise be purchased from a utility. 

         Revenues from cogeneration systems were $761,000, $1,594,000, and
    $873,000 in fiscal 1996, 1995, and 1994, respectively.

         Sponsored Research and Development. The Company conducts research
    and development supported by outside sponsors. Revenues from sponsored
    research and development contracts were $5,836,000, $4,917,000, and
    $5,209,000 in fiscal 1996, 1995, and 1994, respectively. See "Research
    and Development."

    Regulation

         The demand for most of the Company's products is affected by
    various federal, state, and local energy and environmental laws and
    regulations. All of these laws and regulations are subject to revocation
    or amendment, and the Company cannot predict what effect revocation or
    amendment may have on the Company's sales, business, or operations.

    Industrial Refrigeration Systems

         The Company's ammonia-based refrigeration equipment and
    alternative-refrigerant commercial cooling systems benefit from the
    worldwide phaseout of CFC refrigerants. The Montreal Protocol was
    negotiated in 1987 under the sponsorship of the United Nations
    Environmental Program (UNEP) to protect the ozone layer. This agreement
    establishes a process to control substances that could deplete the ozone
    layer, including CFCs. Regulations have been promulgated by the EPA
    implementing these protocols in this country through limits on the
    production and consumption of CFCs and other ozone-depleting substances.

    Engines

         The market for the Company's TecoDrive natural gas engine is
    influenced by federal legislation that allows states to establish
    programs encouraging the use of alternative fuels, including natural gas,
    methanol, and ethanol. More than half of the states have some type of
    alternative-fuel vehicles commission, legislation, or tax incentives. In
    addition, many U.S. cities have been classified by the EPA as not meeting
    acceptable air quality standards. By model year 1998, 50% of heavy-duty
    vehicles bought for fleets with 10 or more vehicles capable of refueling
    in these smoggiest cities must be clean-fuel vehicles.

         Under the Clean Air Act Amendments of 1990, the EPA issued
    regulations that delineate clean fuel requirements and vehicle emissions
    standards. In September 1994, the EPA published its final rule on
    certification for propane and natural gas vehicles. In November 1995,

                                        9PAGE

    the Company became the first engine manufacturer to receive EPA
    certification of a heavy-duty natural gas engine for ULEVs. This
    certification certifies that a certain vehicle type or engine meets
    requirements of the most current applicable emissions regulations.

         Natural gas is one of many alternative fuels that is addressed by
    these laws and regulations. Others include methanol, ethanol, liquefied
    petroleum gas, 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 laws or regulations or
    their enforcement will create material long-term demand for NGVs.

    Cooling and Cogeneration Systems

         The passage by Congress of the Public Utility Regulatory Policies
    Act of 1978 (PURPA), the adoption of regulations thereunder by the
    Federal Energy Regulatory Commission (FERC), and related state laws and
    regulations provide incentives for the development of qualifying
    small-power production and cogeneration systems such as those offered by
    the Company. PURPA and FERC regulations promulgated thereunder address
    three issues of importance to users that own or operate cogeneration
    systems, including those sold by the Company. First, PURPA exempts
    qualifying users from many federal and state regulations that pertain to
    electric utilities. Second, PURPA requires electric utilities to allow
    qualifying cogeneration providers to connect their cogeneration
    facilities to utilities' electric power systems. This mandatory
    connection enables users to purchase utility-generated electricity to
    start their cogeneration systems and assures users of a back-up source of
    electricity during peak periods of use and when the cogeneration systems
    are shut down for maintenance and repair. Third, PURPA requires utilities
    to purchase electricity produced by qualifying cogeneration providers at
    a price equivalent to utilities' avoided costs.

         Like all electric power-generating and other fossil fuel-burning
    systems, the Company's cooling and cogeneration products must comply with
    federal, state, and local environmental laws and regulations. Regulation
    of systems such as those sold by the Company is conducted primarily at
    the state and local level, where standards can vary. In particular,
    applicable environmental standards in California are stricter than
    comparable federal guidelines. The Company believes that its existing
    Tecochill and other Tecogen products comply with applicable federal and
    state environmental standards, including those currently in effect in
    California, although the Company cannot predict whether its products will
    comply with all environmental standards promulgated in the future. 

         (ii) New Products

         In March 1995, the Company formed its ThermoLyte subsidiary to
    develop and commercialize a line of gas-powered area lights, flashlights,
    emergency lights, and other lighting products. ThermoLyte's lighting
    products are based on the Company's patented technology for a 


                                       10PAGE

    rigid mantle, the "bulb" in gas lights. This mantle is more durable than
    the mantles typically used in gas lighting and therefore, the Company can
    design its products to be highly portable.

         ThermoLyte has delayed market introduction of its propane-powered
    flashlight to optimize the product's final design. ThermoLyte has
    developed and is now preparing to introduce a propane-powered area light
    to the marketplace. In preparation for introduction of the area light,
    ThermoLyte conducted focus groups to gauge consumer reaction to the
    light's concept, performance, and design. The final design is a
    decorative, contemporary-style area light suitable for providing an
    alternative to candles, oil lamps, or battery-powered lights in the home
    or backyard. Late in calendar 1996, the Company plans to make a limited
    initial market introduction of its area light through a catalog for
    employees and shareholders of Thermo Electron and its subsidiaries. The
    Company is also engaged in qualifying vendors for manufacturing and
    consulting specialty catalog buyers. 

         (iii)  Raw Materials

         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. It does not have a firm
    contract with this supplier. The Company generally maintains inventories
    of engine blocks sufficient to meet its needs for a three-month period.
    However, the inability of the Company to obtain either engines or engine
    blocks from this supplier would have a material adverse effect upon the
    Company's operations.

         (iv)  Patents, Licenses, and Trademarks

         The Company considers its patents and licenses to be important in
    the present operation of its business. The Company, however, does not
    consider any one of its patents or related group of patents to be of such
    importance that its expiration, termination, or invalidity would
    materially affect the Company's business.

         The Company has research and development arrangements with the
    natural gas industry and various governmental agencies, and is required
    to pay royalties for any technologies developed or products
    commercialized under several of these arrangements.

         (v)  Seasonal Influences

         Crusader's marine engine sales historically have been stronger in
    the first quarter of each calendar year, when boat builders purchase
    engines for boats to be sold for the upcoming boating season. Sales of
    marine engines generally decline gradually during the last three quarters
    of the calendar year, reaching their lowest levels in the fourth quarter.
    In addition, the demand for NuTemp's equipment typically has been highest
    in the summer period. However, cool summer weather can adversely affect
    NuTemp's business since the Company's cooling systems are used primarily
    to reduce temperatures below ambient air temperatures. There are no
    significant seasonal influences in the Company's other lines of business.

                                       11PAGE

         (vi)  Working Capital Requirements

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

         (vii)  Dependency on a Single Customer

         No single customer accounted for more than 10% of the Company's
    total revenues in fiscal 1996. In fiscal 1996, revenues from two
    customers accounted for 16% and 10% of Engines segment revenues. The loss
    of one or both of these customers would have a material adverse effect on
    the Engines segment. 

         (viii)  Backlog

         The backlog of firm orders for the Industrial Refrigeration Systems
    segment was $22.2 million as of September 28, 1996, compared with $17.4
    million as of September 30, 1995. The backlog of firm orders for the
    Engines segment was $1.0 million as of September 28, 1996, compared with
    $4.2 million as of September 30, 1995. The backlog of firm orders for the
    Cooling and Cogeneration Systems segment was $4.0 million as of September
    28, 1996, compared with $6.0 million as of September 30, 1995. The
    Company believes that the majority of this backlog will be shipped during
    fiscal 1997. The Company does not believe that the size of its backlog is
    necessarily indicative of intermediate- or long-term trends in its
    business.

         (ix)  Government Contracts

         Not applicable. 

         (x)  Competition

         The Company experiences competition in most of its product lines.
    Additional competition may arise if markets in which the Company is
    active develop significantly. The Company is aware of several competitors
    for its product lines, some of whom have financial, marketing, and other
    resources greater than those of the Company.

    Industrial Refrigeration Systems

         The Company's sale of industrial refrigeration systems is subject
    to intense competition. The industrial refrigeration market is mature,
    highly fragmented, and extremely dependent on close customer contacts.
    Major industrial refrigeration companies, of which FES is one, account
    for approximately one-half of worldwide sales, with the balance generated
    by many smaller companies. The Company believes that FES competes on the
    basis of its advanced control systems and overall quality, reliability,
    service, and to a lesser extent, price.


                                       12PAGE

         The worldwide market is characterized by strong local
    manufacturers. The market leader worldwide as well as in North America is
    Frick Company and its affiliates, subsidiaries of York International
    Corporation (York). Though comprehensive surveys on the industrial
    refrigeration market do not exist, the Company believes it accounts for
    approximately 20% of the North American market, 2% of the European
    market, 4% of the Asia-Pacific market, and 1% of the Latin American
    market.

         The Company believes NuTemp is the world leader in remanufactured
    refrigeration equipment. As part of its rental program, NuTemp offers an
    option to buy its equipment, a service that is unique in the industry.
    NuTemp's largest competitor is Aggreko, a subsidiary of Christian
    Salverson Company. Aggreko is a major supplier of rental equipment for
    the industrial refrigeration and commercial cooling markets. The Company
    believes that NuTemp competes on the basis of price, delivery time, and
    customized equipment.

    Engines

         Competition in the CNG vehicle and alternative-fuel engine markets
    is intense, and current or 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 those of the
    Company.

         The Company believes it has the second largest share of the inboard
    marine engine market for cruiser class boats in the United States, with
    about 25% market share, behind the Mercury division of Brunswick
    Corporation. Crusader has experienced intense competition in the marine
    engine business in recent years, primarily from vertical integration of
    boat and engine manufacturers that has led to the acquisition of former
    Crusader customers by competing engine manufacturers. The Company
    believes that Crusader competes on the basis of quality, reliability,
    service, and pricing.

    Cooling and Cogeneration Systems

         The Company's Tecochill products are subject to competition from
    absorption air conditioning systems and electric motor-driven vapor
    compressor systems. Other manufacturers of natural gas-fueled
    engine-driven cooling systems have also entered the market. The Company
    believes it competes with producers of conventional cooling equipment on
    the basis of relative operating costs at times of peak electrical demand,
    and with other producers of natural gas-fueled cooling systems on the
    basis of quality, reliability, service, operational savings, and track
    record.

         In 1995, Enchill by MKW Power Systems, one of the Company's major
    competitors, ceased operations in the gas-cooling market. Also in 1995,
    York entered the gas-engine cooling market, in partnership with
    Caterpillar, and is a major competitor in large-capacity (+400 tons)
    cooling equipment. However, the Company's most competitive range is in
    smaller-capacity equipment.

                                       13PAGE

         The Company's sale of cogeneration systems is subject to intense
    competition, both direct and indirect. Direct competitors consist of
    companies that sell cogeneration products resembling those sold by the
    Company. In addition, electric utility pricing programs provide
    competition for the Company's cogeneration products. Indirect competitors
    include manufacturers of conventional water heaters, air conditioners,
    and electric generator sets, since the economic benefits of the Company's
    cogeneration and cooling systems depend on the cost of conventional
    energy systems. The Company believes that it competes on the basis of
    several factors, including product quality and reliability, operational
    savings, ease of installation, service, and pricing.

         The Company's sponsored research and development is also subject to
    intense competition from many larger and smaller firms, universities, and
    other private and public research facilities. The Company competes for
    sponsored research and development contracts on the basis of several
    factors, including technical expertise, market experience, and past
    performance.

         (xi)  Research and Development 

         The Company has conducted research and development on applications
    of thermal energy for more than 30 years. The Company's research and
    development capability and expertise in engine, instrumentation, control,
    and heat-recovery technologies have enabled it to obtain support from
    outside sponsors, develop new products, and support existing products. 

         The Company's sponsored programs have been supported principally by
    the domestic natural gas industry and the federal government. Within the
    natural gas industry, the Company's principal sponsors have been the Gas
    Research Institute (GRI) and the Southern California Gas Company, which
    is the nation's largest gas utility. The Company has also obtained
    research and development funding from federal and state governments,
    industrial companies, and from the Electric Power Research Institute.
    Sponsors of the Company's research and development generally own the
    rights to technology that is developed under these programs.

         As part of the Company's research and development of combustion
    technology, ThermoLyte is developing a family of gas-powered lighting
    products, including area lights, flashlights, emergency lights, and other
    lighting products. ThermoLyte's lighting products are based on the
    Company's patented technology for a rigid mantle, the "bulb" in gas
    lights. By incorporating this durable mantle into its lights, the Company
    can use propane as a power source instead of batteries.

         The Company is developing a unique thermophotovoltaics (TPV)
    technology with funding from the U.S. Department of Defense. TPV is a
    solid-state system that converts a gaseous or liquid fuel such as diesel
    to electric power without the aid of any moving parts. The goal is to
    replace conventional diesel engine generators with a more reliable and
    lightweight system to recharge batteries used in electronic devices.
    Potential commercial applications for TPV are power generation for
    recreational, commercial, and military uses, as well as power cells for
    electronic equipment. However, the development of TPV is in the 

                                       14PAGE

    very preliminary stages, and no assurance can be given that the Company
    will be able to develop a commercially viable TPV product.

         The Company is also continuing to develop additional applications
    for its thermoelectric cooling modules. Currently, these cooling modules
    are used to control the temperature of laser diodes in fiber-optic
    telecommunication equipment and biomedical instruments, as well as TRSs,
    which are used for calibrating infrared imaging systems. 

         During fiscal 1996, 1995, and 1994, the Company spent $3,214,000,
    $3,065,000, and $1,622,000, respectively, on internally funded research
    and development, and $4,444,000, $3,548,000, and $4,197,000,
    respectively, on research and development sponsored by others.

         (xii)  Environmental Protection Regulations

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

         (xiii)  Number of Employees

         As of September 28, 1996, the Company employed approximately 550
    people. Approximately 39 employees at the Company's Crusader division are
    represented by a labor union under a three-year collective bargaining
    agreement expiring on October 15, 1997. The Company has experienced no
    work stoppages in the past, and considers its relations with employees to
    be good.

         (xiv)  Marketing

    Industrial Refrigeration Systems

         FES's products are distributed primarily through independent sales
    representatives who are typically specialists in industrial
    refrigeration, and they are also sold directly to end users.
    Approximately 75% of FES's sales are in North America. Of the sales
    generated in North America, 90% are made by independent sales
    representatives, 5% by FES sales employees, and 5% through direct orders
    from existing customers. FES has 12 independent sales offices serving all
    business regions throughout the United States. All of the independent
    sales representatives are engineers who have the ability to provide
    customers with quotes on entire refrigeration plants. The representatives
    make sales contacts with refrigeration contractors, end users, and
    consulting engineers. Sales of FES's standard food and beverage packages
    are generally made to refrigeration contractors who are responsible for
    installation of the total refrigeration plant at the facility of an end
    user. Sales of FES's custom systems are generally made directly to end
    users.

         Export sales accounted for approximately 20% of FES's fiscal 1996
    revenues. FES uses a combination of FES employees with demonstrated 

                                       15PAGE

    industrial refrigeration expertise and several independent
    representatives located in various countries, including Thailand, Taiwan,
    the People's Republic of China, and Russia.

         NuTemp markets its products through direct marketing techniques,
    including direct mailing, and sends representatives to numerous trade
    shows each year. NuTemp is also marketing its products through FES sales
    employees and independent sales representatives. NuTemp's sales are made
    solely in the United States.

    Engines

         The Company markets its TecoDrive natural gas engines principally
    through a series of nonexclusive OEM and distributor arrangements. The
    Company also sells its TecoDrive engines for stationary applications to
    manufacturers in Europe, South America, and the Middle East, and is
    actively pursuing the distribution of TecoDrive engines in Canada. The
    Company has sales representatives who market the Company's engines
    through an expanded network of distributors. By working through a
    distributor with comprehensive overhaul, repair, spare parts, field
    service, and training capabilities, the Company's engine customers in the
    United States and Canada can receive aftermarket support.

         The Company has marketed TecoDrive engines for irrigation
    applications through a variety of channels. The engines have been
    exhibited at a number of agriculture industry trade shows, and they have
    been featured in advertisements in agricultural trade journals. The
    Company has organized a network of dealers in large agricultural states,
    including Arizona, California, Nebraska, Kansas, and Oklahoma, which is
    independent of the distribution network discussed above, specifically for
    the distribution of TecoDrive engines for irrigation applications.
    Southwest Gas Company in Arizona and Southern California Gas Company in
    California are also supporting the Company's marketing effort for
    irrigation engines by offering cash rebates to farmers purchasing
    TecoDrive engines to replace electric motors or diesel engines in pumping
    service.

    Cooling and Cogeneration Systems

         The Company markets its Tecochill cooling units primarily through a
    network of distributors located throughout the United States. The Company
    has established its own network of sales representatives, and the
    Company's marketing effort in the United States is also supported by a
    consortium of gas and combined gas-electric utilities. The Company
    markets its cogeneration units in the United States through its own sales
    force, and in certain areas, through a team of distributors. The Company
    has commenced some sales of its smaller cogeneration products outside the
    United States.

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

         We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Thermo Power
    Corporation's Annual Report to Shareholders incorporated by reference in
    this Form 10-K, and have issued our report thereon dated November 1,
    1996. Our audits were made for the purpose of forming an opinion on those
    statements taken as a whole. The schedule listed in Item 14 on page 20 is
    the responsibility of the Company's management and is presented for
    purposes of complying with the Securities and Exchange Commission's rules
    and is not part of the basic consolidated financial statements. This
    schedule has been subjected to the auditing procedures applied in the
    audits of the basic consolidated financial statements and, in our
    opinion, fairly states in all material respects the consolidated
    financial data required to be set forth therein in relation to the basic
    consolidated financial statements taken as a whole.
