                                     PART I

    Item 1. Business

    (a)  General Development of Business

         Thermo Ecotek Corporation (the Company or the Registrant) is an
    environmental company providing a range of environmentally responsible
    technologies and products, including non-utility electric power
    generation using clean combustion processes, engineered clean fuels - as
    well as environmentally friendly pest control products through its
    biopesticides subsidiary, Thermo Trilogy Corporation (Thermo Trilogy).

         The Company operated as a division of Thermo Electron Corporation's
    (Thermo Electron's) Energy Systems Division (the Division) from 1979
    until its incorporation as Thermo Energy Systems Corporation in November
    1989. On January 2, 1990, Thermo Electron transferred certain of the
    assets and business of the Division to the Company in exchange for
    10,500,000 shares of common stock and the assumption by the Company of
    certain liabilities of the Division. In connection with this transfer,
    Thermo Electron agreed to indemnify the Company against any losses,
    costs, or damages incurred by the Company as a result of the conduct of
    the business of the Division prior to the transfer date. On January 2,
    1990, Thermo Electron and the Company signed an Agreement and Plan of
    Reorganization to recapitalize $10 million of loans made to the Company
    by Thermo Electron into 1,111,111 shares of redeemable convertible
    preferred stock. These shares were issued in May 1990 and were converted
    into 1,666,667 shares common stock during 1993 at a conversion price of
    $6.00 per share. In December 1994, the Company changed its name to Thermo
    Ecotek Corporation. The Company completed an initial public offering in
    February 1995. In March 1996, the Company issued and sold at par $37
    million principal amount of noninterest-bearing subordinated convertible
    debentures due 2001. The debentures are convertible into shares of the
    Company's common stock at a conversion price of $13.56 per share and are
    guaranteed on a subordinated basis by Thermo Electron. 

         Initially, the Division designed, developed, and acted as general
    contractor for the construction of cogeneration systems fueled by natural
    gas and diesel. These turnkey facilities were generally sold to third
    party operators upon completion and had a total generating capacity of
    approximately 60 megawatts. In the mid-1980s, the Division began
    developing biomass-fueled power plants to take advantage of a favorable
    regulatory environment and attractive power sales agreements. Biomass
    plants use environmentally responsible fuels including wood and
    agricultural wastes.

         The Company currently operates seven biomass facilities with a
    total electric generating capacity of 140 megawatts. The Company develops
    and operates its facilities through joint ventures or limited
    partnerships in which the Company has a majority interest, or through
    wholly owned subsidiaries (the Operating Companies).
                                        2PAGE
<PAGE>
         In September 1996, the Company, through a wholly owned subsidiary,
    formed a joint venture with Marcegaglia Group of Mantova, Italy to
    develop, own, and operate biomass-fueled electric power facilities in
    that country.

         In January 1996, the Company, through a wholly owned subsidiary,
    signed a joint development agreement with a Czech/American power
    development company, EMD Praha Spol s.r.o. The initial focus will be on
    expansion and environmental retrofits of existing Czech energy centers.

         The Company is expanding beyond biomass power generation into other
    products and processes that protect the environment. In May 1996, two of
    the Company's wholly owned subsidiaries, acquired the net assets of the
    W.R. Grace & Co.'s biopesticide unit for approximately $8.1 million. In
    addition, the Company will pay a royalty fee of seven percent on annual
    sales of the acquired business in excess of $14 million through the year
    2000. Renamed Thermo Trilogy, the subsidiary develops, manufactures, and
    markets environmentally friendly products used for pest control. Derived
    from seeds of the tropical "neem" tree and pesticidal microbials isolated
    from nature, these biopesticides safely and effectively control insects,
    diseases, and mites on numerous crops. The state of California recently
    approved Trilogy(TM) 90EC, a neem oil-based miticide and fungicide, for
    use by California growers of fruits and vegetables. Thermo Trilogy's neem
    based products, Neemix(R) and Trilogy(TM) 90EC, are both approved for use
    on certified organic products.

         The Company has also entered into the field of engineered "clean"
    fuels, through a partnership agreement with KFx Inc. (KFx). In August
    1995, the Company, through two wholly owned subsidiaries, entered into a
    Limited Partnership Agreement with KFx Wyoming, Inc., a subsidiary of
    KFx. The Company is committed to provide approximately $48 million for
    the design, construction, and operation of the first full-scale coal
    production facility to use the patented K-Fuels "clean coal" technology.
    The Company will have a 95% equity interest in the plant. Once completed,
    the Gillette, Wyoming facility will transform high-moisture, low-energy
    coal into 500,000 tons per year of low-moisture, high-energy, solid fuel,
    using the Koppelman "C" process. KFx holds certain rights to this
    process, which produces coal known as K-Fuels for utility and industrial
    use. Construction began in August 1995, with commercial operation
    expected to commence in the first half of fiscal 1997.

         In August 1995, the Company purchased 1,500,000 shares of KFx
    common stock representing an approximate 7% equity interest in KFx. The
    cost of the purchase was $3,000,000. In fiscal 1996, the Company
    purchased an additional 1,500,000 shares of KFx common stock for  
    $3,000,000, bringing its total equity interest in KFx to approximately
    14%. The Company has the right, but not the obligation, to purchase an  
    additional 1,250,000 shares of common stock at $2.00 per share at certain
    times in fiscal 1997, if such shares are made available by KFx, as well
    as warrants, exercisable from January 1, 2000 through July 1, 2001, to
    purchase up to a total 51% equity interest in KFx. These warrants will
    terminate if the Company does not acquire all of the shares made
    available by KFx in 1997.
                                        3PAGE
<PAGE>
         In July 1995, the Company entered into an agreement to invest $15
    million in a 185-megawatt combined cycle, steam-turbine electric
    generation facility located in Puerto Plata, Dominican Republic, owned by
    Smith/Enron Cogeneration Limited Partnership (SECLP). Under the terms of
    the agreement, the Company will acquire both a general and limited
    partnership interest in Smith Cogeneration Dominicana L.P. (Smith
    Cogeneration), which through its investment in SECLP, owns approximately
    50% of the project. The Company will receive a minority interest in Smith
    Cogeneration equivalent to a specified percentage of all project cash
    flow and profits and losses. The Company's exact percentage interest in
    Smith Cogeneration will not be finally determined until six months after
    the funding of the Company's investment, which is expected to occur
    during calendar 1997, assuming certain conditions are met.

         In June 1995, the Company changed its fiscal year end from the
    Saturday nearest December 31 to the Saturday nearest September 30.
    References to "fiscal 1996," "fiscal 1995," and "1994" herein are for the
    year ended September 28, 1996, the nine months ended September 30, 1995,
    and the year ended December 31, 1994, respectively.

         At September 28, 1996, Thermo Electron owned approximately 83% of
    the Company's outstanding common stock, giving Thermo Electron the power
    to elect all Directors of the Company. 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. Thermo Electron
    intends for the foreseeable future to maintain at least 80% ownership of
    the Company, so that it may continue to file consolidated U.S. federal
    income tax returns with the Company. This will require the purchase by
    Thermo Electron of additional shares of the Company's common stock from
    time to time as the number of outstanding shares issued by the Company
    increases. These purchases may be made either on the open market or
    directly from the Company. During fiscal 1996, Thermo Electron purchased
    898,159 shares of the Company's common stock in the open market for a
    total price of $12,717,000. The Company has sold $68.5 million of
    subordinated convertible debentures to Thermo Electron that could be
    converted to maintain at least 80% ownership by Thermo Electron.

         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 currently operates in predominantly one business
    segment: the design, development, and operation of independent
    (non-utility) electric power generation facilities using a range of
    environmentally responsible combustion technologies. In addition, the
                                        4PAGE
<PAGE>
    Company's newly formed Thermo Trilogy subsidiary is engaged in the
    development, manufacture, and marketing of biopesticides, and the Company
    has entered the field of engineered "clean" fuels through its partnership
    with KFx. Neither of these new business segments were significant to the
    Company's operations in fiscal 1996.

         Hemphill. The Hemphill facility, a 13.6-megawatt, wood-waste plant,
    was completed in late 1987. It is located on a 50-acre site in
    Springfield, New Hampshire. The Operating Company is a joint venture in
    which the Company has a 67% interest. The Hemphill facility is owned by
                                        5PAGE
<PAGE>
    BancBoston Leasing Services Inc., which leases the facility to the
    Operating Company through March 2003. Public Service of New Hampshire
    (PSNH) purchases power produced by the plant at a fixed rate under a rate
    order issued by the New Hampshire Public Utility Commission (NHPUC)
    expiring in 2006. The Operating Company purchases wood-waste pursuant to
    two contracts with affiliates of the Company's joint venture partner,
    each of which expires in 2003. The contracts provide for the supply of  
    wood-waste to the Operating Company at prescribed prices through 1997 and
    at market prices thereafter. In 1990, a plan of reorganization (the Plan)
    for PSNH was approved by the U.S. Bankruptcy Court for the District of
    New Hampshire. Pursuant to the Plan, Northeast Utilities (NU) acquired
    the assets of PSNH. An agreement between NU and the state of New
    Hampshire contains language to the effect that PSNH will seek to
    renegotiate some terms of certain rate orders directly with small power
    producers, and that the state will support PSNH in such efforts. PSNH has
    sought to renegotiate the rate orders applicable to the Company's
    facilities, and the state, acting through NHPUC, has supported such
    efforts. Based on negotiations between the two New Hampshire Operating
    Companies and PSNH during fiscal 1995, the Company believes that this
    matter may reach resolution in fiscal 1997, although final resolution is
    subject to approval of the NHPUC. Should the matter not reach resolution,
    the Company does not believe that PSNH has the right to take unilateral
    action to reduce the price of power purchased under the rate order. See
    "Management's Discussion and Analysis of Financial Condition and Results
    of Operations" incorporated by reference into Item 7 hereof.

         Gorbell. The Gorbell facility, a 13.6-megawatt wood-waste plant,
    was completed in late 1987. It is located on a 56-acre site in Athens,
    Maine. The design of the facility is substantially similar to the
    Hemphill plant. The Operating Company is a joint venture in which the
    Company has an 80% interest, which declines to 60% in 1998. The Gorbell
    facility is owned by BancBoston Leasing Services Inc., which leases the
    facility to the Operating Company through March 2003. Power produced by
    the plant is sold to Central Maine Power Company (CMP) through 2007 at a
    fixed price per kilowatt hour that is indexed annually to the rate of
    inflation. The Operating Company's fuel is purchased from an affiliate of
    the Company's joint venture partner pursuant to an agreement expiring in
    2002 under which the price escalates based upon a prescribed index.

         Whitefield. The Whitefield facility is a 13.6-megawatt wood-waste
    plant that has been in operation since 1988. It is located on a 46-acre
    site in Whitefield, New Hampshire. The power produced by the plant is
    sold to PSNH at established rates under a power sale agreement that
    expires in 2005. This plant is also subject to PSNH's attempt to
    renegotiate rate orders. See "Hemphill" above. Fuel is purchased pursuant
    to an agreement expiring in 1998 under which the price escalates based
    upon a prescribed index. The Whitefield facility was originally owned by
    Chrysler Capital Corp., and leased to the Operating Company. The Company
    purchased the Whitefield facility in August 1992. 

         Mendota. The Mendota facility is a 25-megawatt agricultural and
    urban wood-waste plant that has been in operation since 1990. It is
    located on an 80-acre site in Mendota, California. The Operating Company
    is a limited partnership, 60% of which is owned by the Company. The
    facility is owned by Chrysler Capital Corp., which leases the facility to
                                        6PAGE
<PAGE>
    the Operating Company through 1999 at which point the Company will have
    an option to purchase the facility for $5 million. In June 1995, the
    Operating Company amended the facility lease which resulted in the
    agreement being treated as a capital lease. See "Management's Discussion
    and Analysis of Financial Condition and Results of Operations"
    incorporated by reference into Item 7 hereof. The power generated by the
    plant is sold to Pacific Gas & Electric (PG&E) under a standard offer #4
    (SO#4) contract expiring in 2014. Under the contract, PG&E is required to
    purchase the plant's electricity at predetermined prices until 2000, and
    at a price equal to PG&E's avoided-cost for the remainder of the
    contract. Payments for capacity are fixed. PG&E has asserted that the
    fixed rates under this contract will terminate mid-1999, however, the
    Company disputes this assertion. Approximately 45% of the fuel for the
    plant is purchased pursuant to long-term contracts terminating between
    1998 and 2002, under which prices increase in accordance with prescribed
    schedules or market-based indexes. The remainder of the plant's fuel is
    purchased by the Operating Company on the spot market.

         The power sale agreements between the Mendota and Woodland
    (discussed below) Operating Companies and PG&E allow PG&E to curtail the
    quantity of power purchased under these agreements by up to 1,000 hours
    of generating capacity annually at each plant. PG&E normally exercises
    its curtailment rights during periods when cheaper hydroelectric power is
    available, which generally occurs following periods of heavy rain or
    snow. Curtailment reduces the power payment received by the Operating
    Companies and, therefore, has an adverse effect on the financial results
    of those Operating Companies. The Company experienced approximately 930
    hours of utility imposed curtailments during fiscal 1996 at each plant.
    During November 1995, the Woodland and Mendota plants reached the
    contractual limit of 1,000 hours of curtailment for calendar 1995.

         Woodland. The Woodland facility is a 25-megawatt agricultural and
    urban wood-waste plant located on a 38-acre site in Woodland, California.
    The design of the plant is essentially the same as the Mendota plant. The
    Operating Company is a limited partnership in which the Company owns all
    of the equity. The facility is owned by BancBoston Leasing Services Inc.,
    which leases the facility to the Operating Company through March 2010.
    The electricity generated by the plant is sold to PG&E under an SO#4
    contract expiring in 2014, at predetermined prices until 2000. PG&E has
    asserted that the fixed rates under this contract will terminate
    mid-1999, however, the Company disputes this assertion. The price for the
    remainder of the contract is PG&E's avoided-cost. Payments for capacity
    are fixed. Approximately 20% of the fuel for the plant is purchased
    pursuant to long-term contracts terminating in 2000, under which prices
    increase in accordance with prescribed schedules or market based indexes.
    The remaining fuel is purchased by the Operating Company on the spot
    market.

         Beginning in 1996, the Operating Company has conditions in its
    nonrecourse lease agreement, that require the funding of a "power
    reserve" in years prior to 2000, based on projections of operating cash
    flow shortfalls in 2000 and thereafter. The power reserve represents
    funds available to make lease payments in the event that revenues are not
    sufficient after the plant converts to avoided-cost rates in March 2000.
    This funding requirement will significantly limit future profit
                                        7PAGE
<PAGE>
    distributions the Operating Company may make to the Company. Accordingly,
    beginning in the first quarter of fiscal 1997, the Company expects to
    expense the funding of reserves required under Woodland's nonrecourse
    lease agreement to cover projected shortfalls in lease payments beginning
    in 2000. As a result, the Company expects that the results of the
    Woodland plant will be reduced to approximately breakeven beginning in
    fiscal 1997, and thereafter. During fiscal 1996, the Woodland plant
    contributed $5.1 million of operating income.

         Delano I. The Delano I facility is a 27-megawatt agricultural and
    urban wood-waste plant located on a 124-acre site in Delano, California.
    Southern California Edison (SCE) purchases power under an SO#4 contract
    expiring in 2020, under which energy prices are predetermined until
    September 2000, and then at avoided-cost for the remainder of the
    contract. Approximately 60% of the fuel supply is purchased pursuant to
    long-term contracts with terms expiring from 1997 to 2004 under which
    prices increase in accordance with prescribed schedules or market based
    indexes. The remaining fuel is purchased by the Operating Company on the
    spot market. The Company has guaranteed to the Operating Company the
    price and availability of fuel that is not purchased pursuant to the
    long-term contracts. The Delano I facility was originally owned by
    Westinghouse Credit Corporation and leased to the Company. In December
    1993, the Company purchased Delano I for $21.5 million in cash and the
    assumption of $66.9 million of nonrecourse, long-term, tax-exempt bonds
    issued by the California Pollution Control Finance Authority (CPCFA).
    These bonds bear interest at a rate of 8.3%, with principal and interest
    payable semi-annually until maturity in 2000. The cash portion of the
    purchase price was funded by borrowings from Thermo Electron. 

         Delano II. In January 1994, the Delano Operating Company commenced
    operation of phase II of the Delano project, a 22-megawatt agricultural
    and urban wood-waste plant located on the same site as Delano I. The
    facility is wholly owned by the Delano Operating Company. Power generated
    by the Delano II facility is also purchased by SCE under the Delano I
    contract described above, under which prices are fixed until September
    2000. Fuel is also purchased pursuant to the same contracts as Delano I.
    The Delano II facility is owned by the Company and is subject to $66
    million principal amount of nonrecourse, long-term tax-exempt bonds
    issued by CPCFA. These bonds bear interest at a rate of 6%, with
    principal and interest payable semi-annually until maturity in 2000.

    Projects in Development

         Czech Republic

         In January 1996, the Company, through a wholly owned subsidiary,
    signed a joint development agreement with a Czech/American power
    development company, EMD Praha Spol s.r.o. The initial focus will be on
    expansion and environmental retrofit of existing Czech energy centers. To
    support this effort, the Company has opened an office in Prague. The
    projects are subject to a number of conditions including negotiation of
    definitive agreements for power sale, fuel supply, and other agreements
    with third parties. No assurance can be given that conditions or
    agreements will be satisfied on a timely basis. The Company does not
    believe that any of the projects will be operational before 1999.

         Italy

         In September 1996, the Company, through a wholly owned subsidiary,
    formed a joint venture (the Joint Venture) with Marcegaglia Group of
    Mantova, Italy, to develop, own, and operate biomass-fueled electric
    power facilities in that country. The Joint Venture has begun preliminary
    evaluation of approximately 10 facilities, seven of which have already
    been approved by the Italian government's price subsidy program for
    biomass-fueled plants. In addition, several of the projects may qualify
    for European Union grants, covering a portion of the capital costs. The
    Joint Venture is currently establishing an office near Milan to
    coordinate the process of analyzing site locations as well as potential
    fuel sources and the appropriate technology choices for these facilities.
    The facilities are subject to a number of conditions including
    negotiation of definitive agreements for power sale, fuel supply, and
    other agreements with third parties. No assurance can be given that
    conditions or agreements will be satisfied on a timely basis. The Company
    does not expect that any of the projects will be operational before 1999.

         India

         Gouripore - The Company is in the initial stages of developing the
    Gouripore Thermal Power Station project, a 150-megawatt coal-fueled
    electricity generation plant using fluidized bed combustion to be located
    in Gouripore, West Bengal, India. The Gouripore project is one of the 70
    projects initially identified by the Indian government as part of a
    program to develop 70,000 additional megawatts of generating capacity by
    2002. The Company has entered into a memorandum of understanding with two
    India-based companies relating to the development of the project. The
    Company would be the majority owner of the project. To support this
    project, the Company has opened an office in Calcutta, from which it will
    evaluate other opportunities in India. The total financing requirement of
    the project is expected to be approximately $240 million, which is
    expected to involve significant equity investments and bank borrowings.

         The Company is in the process of negotiating a power sale agreement
    with the West Bengal State Electricity Board and is seeking a payment
    guarantee of the State Electricity Board's obligations from the West
    Bengal government, although there can be no assurance that such a
    guarantee will be obtained or that such a guarantee will be sufficient to
    obtain financing for the project. The project is subject to a number of
    conditions, including negotiation of definitive agreements with the
    Company's partners, as well as negotiation of power sale, fuel supply,
    and other agreements with third parties. No assurance can be given that
    these conditions will be satisfied on a timely basis, or at all.

         Bangalore - The Company is also in the initial stages of developing
    the IPS Power project, a 105-megawatt combined cycle, gas turbine
    electricity generation plant to be located near Mysore in the state of
    Karnataka, India. The Bangalore project is one of eight projects that
    received a state order allowing development of 500 additional megawatts
    of generating capacity. To support this project, the Company has opened
    an office in Bangalore. The total financing of the project is expected to
    be approximately $110 million, which is expected to involve significant
    equity investments and bank borrowings.

    Engineered Clean Fuels

         KFx, Fuel Partners, L.P. In August 1995, the Company, through two
    wholly owned subsidiaries, entered into a Limited Partnership Agreement
    with KFx Wyoming, Inc. (the Partnership) a subsidiary of KFx Inc., to
    develop, construct, and operate a subbituminous coal beneficiation plant
    to be constructed near Gillette, Wyoming. The Partnership has been
    granted, in exchange for certain future contingent royalty payments, a
    non-exclusive right and license to use certain patented clean coal
    technology (K-Fuel) to create a low-moisture, high-energy fuel with
    reduced sulfur that will help coal-burning utilities meet the SO2
    emission restrictions contained in the Clean Air Act. See "Regulatory
    Matters -- Domestic Energy Regulation." The Partnership has procured a
    24-acre site for construction of the plant and began construction in
    August 1995 under a third party, turnkey construction contract. The plant
    is expected to begin commercial operations in the first half of fiscal
    1997. In return for up to a 95% equity interest in the plant, the Company
    is committed to provide approximately $48 million for the design,
    construction, and operation of the plant. Costs to complete construction
    increased approximately $6.0 million primarily due to changes in certain
    portions of the construction project. During 1996, the U.S. government
    enacted legislation granting an 18-month extension of the Oil Barrel
    Equivalent tax credit for facilities producing alternative fuels, such as
    K-fuel. To be eligible, companies must enter into binding, written
    contracts for the construction of the facility, by December 31, 1996, and
    facilities must be in operation no later than July 31, 1998. In light of
    the new legislation, the Company has extended its construction schedule
    and is currently engaged in a feasibility study for the expansion of the
    production capacity of the facility under construction. The K-Fuel
    technology has not been tested on a large scale, and no assurance can be
    given that the plant, when constructed, will not experience technical
    problems or that the plant's production capacity will be expanded
    pursuant to the feasibility study.

         In August 1995, the Company purchased 1,500,000 shares of KFx Inc.
    common stock, representing an approximate 7% equity interest in the
    Company. The cost of the purchase was $3,000,000. In fiscal 1996, the
    Company purchased an additional 1,500,000 shares of KFx common stock for
    $3,000,000, bringing its total equity interest in KFx to approximately
    14%. The Company has the right, but not the obligation, to purchase an
    additional 1,250,000 shares of common stock at $2.00 per share in fiscal
    1997, if such shares are made available by KFx, as well as warrants,
    exercisable from January 1, 2000 through July 1, 2001, to purchase up to
    a total 51% equity interest in KFx. These warrants will terminate if the
    Company does not acquire all of the shares made available by KFx in 1997.
    See Note 3 of Notes to Consolidated Financial Statements in the
    Registrant's 1996 Annual Report to Shareholders incorporated by reference
    into Item 8 hereof.

    Biopesticides

         In May 1996, the Company, through two of its wholly owned
    subsidiaries, acquired the net assets of a W.R. Grace & Co. business unit
    (renamed Thermo Trilogy) that develops, manufactures, and markets
    environmentally friendly products used for pest control, for
    approximately $8.1 million in cash. In addition, the Company will pay a
    royalty fee of seven percent on annual sales of the acquired business in
    excess of $14 million through the year 2000.

         Most of the biopesticide products produced by Thermo Trilogy are
    derived from the seed of tropical neem trees. Azadirachtin and neem oil,
    both extracts from neem seeds, are effective at controlling more than 200
    species of agricultural insects and diseases. The Company markets its
    neem-derived products under the trademarked names, "Trilogy," "Triact,"
    "Neemix," and "Neemazad."

         Resembling the structure of insect hormones, azadirachtin disrupts
    insects' molting process, significantly deterring feeding and egg laying.
    Azadirachtin products must be ingested to be effective. Only insects that
    feed on plant tissue succumb. Therefore, unlike most chemical pesticides,
    these botanical extracts leave beneficial insects unharmed. Neem
    oil-based products are also effective against fungi and various mites.

         The Company also markets a microbial product trademarked
    "SoilGard," a soil fungicide used to combat "damping off" disease in
    greenhouse ornamentals and vegetable seedlings, as well as PFR, an
    entomopathogentic fungus that paratizes and kills insects.

         The Company expects that it will need to educate growers regarding
    the effective use of biopesticides since using these naturally derived
    products requires pest management practices different from conventional
    chemical pesticides. Although response from growers to date has been
    positive, there is no assurance that the Company will be able to convince
    them to change their pest management practices. Additionally, until its
    acquisition of Thermo Trilogy, the Company had no experience in product
    marketing and merchandising. There is no assurance that the Company will
    be successful selling its biopesticide products to the agricultural
    market.

    Regulatory Matters

         The Company is subject to energy and environmental laws and
    regulations at the federal, state, local, and international levels in
    connection with the development, ownership, and operation of its plants.
    Federal laws and regulations govern power purchase and sale transactions
    with regulated utility companies, the types of fuel that may be used by a
    plant, the ownership of a plant, the plant's efficiency, and the type and
    use of combustion and pollution control technology at a plant. State
    utility regulatory commissions must establish the rates and, in some
    instances, other terms and conditions under which public utilities
    purchase electric power from non-utility generators. Under certain
    circumstances where specific exemptions are otherwise unavailable, state
    utility regulatory commissions may have broad jurisdiction over
                                       11PAGE
<PAGE>
    non-utility electric power plants. Energy-producing projects also are
    subject to federal, state, local, and international laws, as well as
    administrative regulations governing the emissions and other substances
    produced by a plant, and geographical location, zoning, and land use.

    Domestic Energy Regulation

         Public Utility Regulatory Policies Act of 1978, as amended (PURPA).
    The U.S. market for non-utility generators developed after the passage of
    PURPA. Prior to the passage of PURPA, regulated utilities were the
    primary producers of electric power. PURPA was passed in the wake of the
    energy crises of the 1970s as a means to increase energy efficiency and
    foster the development of alternative power generation technologies. The
    1978 enactment of PURPA and the adoption of regulations thereunder by the
    Federal Energy Regulatory Commission (FERC) provided incentives for the
    development of cogeneration and small power production facilities.

         A domestic electricity generating project must be a Qualifying
    Facility, or "QF", in order to take advantage of certain rate and
    regulatory incentives provided by PURPA. To qualify as a QF, a plant must
    be a cogeneration facility or small power producer (less than 80
    megawatts) that burns waste or alternative fuels, and an electric utility
    or its subsidiary must not own more than 50% of the economic interest in
    the plant. PURPA exempts QFs from the Public Utility Holding Company Act
    of 1935 (PUHCA), most provisions of the Federal Power Act (the FPA) and,
    except under certain limited circumstances, state laws concerning rate or
    financial regulation. Each of the plants that the Company currently owns
    and operates meets the requirements under PURPA necessary for QF status.

         PURPA provides two primary benefits to QFs. First, QFs are relieved
    of compliance with extensive federal, state, and local regulations that
    control the development, financial structure, and operation of any
    energy-producing plant and the prices and terms on which energy may be
    sold by the plant. Second, FERC's regulations promulgated under PURPA
    require that electric utilities purchase electricity generated by QFs, at
    a price based on the purchasing utility's full "avoided cost." This is
    defined as the incremental cost to an electric utility of electric energy
    or capacity that the utility would have to generate itself or purchase
    from another source if it did not have power available from the QF. FERC
    regulations also permit QFs and utilities to negotiate agreements for
    utility purchases of power at rates lower than the utility's avoided
    costs. While public utilities are not explicitly required by PURPA to
    enter into long-term contracts, PURPA helped to create a regulatory
    environment in which it has become common for long-term contracts to be
    negotiated. While all of the Company's existing projects have long-term
    power sale agreements at rates equal to or greater than the utilities'
    current avoided-costs, the current practice is for most power sale
    agreements to be awarded at a rate below avoided-cost, due to increasing
    competition for utility contracts. Moreover, whereas in the 1980s power
    sale agreements were often entered into as a result of negotiations
    between a non-utility generator and a utility, increasingly, these
    agreements are the subject of competitive bidding, which tends to lower
    the price that a non-utility generator may receive for power. Currently,
                                       12PAGE
<PAGE>
    the demand for the construction of cogeneration plants has significantly
    diminished in the U.S. therefore, the Company does not anticipate
    entering into any new construction projects of this type in the near
    future.

         The Company endeavors to design its projects, monitor its
    compliance with applicable regulations, and choose its customers in a
    manner that minimizes the risks of losing QF status for its projects.
    However, if one of the Company's plants should lose its status as a QF,
    the Operating Company would no longer be entitled to the exemptions from
    PUHCA unless the Operating Company qualified as an Exempt Wholesale
    Generator (EWG) under the National Energy Policy Act of 1992. See
    "National Energy Policy Act" below. If the Operating Company was unable
    to qualify as a QF, the facility could be subject to regulation as a
    public utility under the FPA and could result in the Company
    inadvertently becoming a public utility holding company by owning or
    controlling more than 10% of a facility that would no longer be exempt
    from PUHCA. A loss of QF status could result in defaults under the
    Operating Company leases, power sale agreements, and other contracts,
    which could have a material adverse effect on the Company.

         PUHCA. Under the PUHCA, any corporation, partnership, or other
    legal entity that owns or controls 10% or more of the outstanding voting
    securities of a "public utility company," or a company that is a "holding
    company" of a public utility company, is subject to registration with the
    Securities and Exchange Commission and regulation under PUHCA, unless
    eligible for an exemption. PURPA provides that companies that only own
    QFs are not public utility holding companies under PUHCA. A holding
    company of a public utility company that is subject to registration is
    required by PUHCA to limit its utility operations to a single integrated
    utility system and to divest any other operations not functionally
    related to the operation of that utility system. Approval by the
    Securities and Exchange Commission is required for nearly all important
    financial and business dealings of the holding company.

         FPA. The FPA grants FERC exclusive rate-making jurisdiction over
    wholesale sales of electricity in interstate commerce, including ongoing
    as well as initial rate jurisdiction, which enables FERC to revoke or
    modify previously approved rates. These rates may be based on a
    cost-of-service approach or may be determined through competitive bidding
    or negotiation, or, lastly, may be based on other criteria as long as the
    rates are "just and reasonable" and in the public interest. While QFs
    under PURPA are exempt from the rate-making and certain other provisions
    of the FPA, projects not qualifying for QF status would be subject to the
    FPA and to FERC rate-making jurisdiction which may limit their
    flexibility in negotiations with power purchasers.

         National Energy Policy Act. In 1992, Congress enacted comprehensive
    new energy policy legislation in its passage of the National Energy
    Policy Act. This law is primarily designed to foster competition in
    energy production and provide non-utility generators with competitive
    access to the transmission grid. To achieve these goals, the National
    Energy Policy Act amended PUHCA to create Exempt Wholesale Generators
    (EWGs), a new class of generating facility that is exempt from public
    utility regulation under PUHCA. An EWG is an entity determined by FERC to
                                       13PAGE
<PAGE>
    be exclusively engaged, directly or indirectly, in the business of owning
    and/or operating certain eligible facilities and selling energy
    wholesale. EWGs may own facilities of any size, use any fuel source, and
    may be owned by utilities or non-utilities. EWGs may not own transmission
    facilities or otherwise exert market control. The National Energy Policy
    Act also provides new authority to FERC to mandate that owners of
    electric transmission lines provide wheeling access to non-utility
    generators at just and reasonable rates. Previously limited, wheeling
    rights enhance the ability of non-utility generators to negotiate
    transmission access and encourage development of facilities whose most
    feasible siting lies outside the purchasing utility's service area. The
    Company believes that the National Energy Policy Act could benefit the
    Company by expanding its ability to own and operate facilities that do
    not qualify for QF status. However, this legislation may also result in
    increased competition by allowing utilities and others to develop such
    facilities without being subject to the constraints of PUHCA.

         State Regulation. State public utility commissions (PUCs) have
    broad authority to regulate the rates, expenses, financings, and power
    sale transactions of regulated electric utilities. Since a power sale
    agreement will become a part of a utility's expenses (and therefore will
    be reflected in its rates), sale agreements with non-utility generators
    typically fall under the regulatory purview of PUCs. Recognizing the
    competitive nature of the acquisition process, most PUCs will permit
    utilities to "pass through" expenses associated with an independent power
    contract to the utility's retail customers.

         Non-utility generators (including EWGs) that are not QFs under
    PURPA are considered to be public utilities in many states, and are
    subject to broad regulation by PUCs - ranging from the requirement of
    certificates of public convenience and necessity - to regulation of
    organizational, accounting, financial, and other corporate matters.
    Although FERC generally has exclusive jurisdiction over the rates charged
    by such a producer to its wholesale customers, PUCs have the ability, in
    practice, to influence the establishment of such rates by asserting
    jurisdiction over the purchasing utility's ability to pass through the
    resulting cost of the purchased power to its retail customers. In
    addition, states may assert jurisdiction over the siting and construction
    of facilities, and over the issuance of securities and the sale or other
    transfer of assets by these facilities.

         Certain states, including California, Michigan, New York,
    Massachusetts, New Hampshire, and Texas, are considering legislation that
    will remove many of the restrictions that currently limit the ability of
    non-utility generators to sell electrical power directly to industrial
    and commercial customers. The Company believes that the removal of these
    restrictions will result in a greater competition and greater
    opportunities to negotiate power sale agreements with industrial and
    commercial customers and may result in state PUC's attempting to reduce,
    or forcing the renegotiation of, fixed rates or contracts. Although the
    Company believes that the trend in the power market is toward
    deregulation, to date, only a few states have passed any such
    legislation, and there can be no assurance that any further similar
    legislation will ultimately be passed.
                                       14PAGE

         EPA and Related State Regulation. No pesticide may be manufactured,
    used or sold without federal and state approvals. Such approvals, called
    registrations, must be obtained for each individual product formulation
    for use on specific pests for specific crops. Adding new uses, new pests,
    new crops or new formulations requires submission of additional
    applications or data for approval.

         The U.S. Environmental Protection Agency (EPA) regulates pesticides
    under the Federal Insecticide, Fungicide and Rodenticide Act and
    implementing EPA regulations. To obtain a pesticide registration from the
    EPA, the applicant must submit detailed and costly toxicological and
    environmental test results evaluating a pesticide's toxic and other
    impacts on plants, pests, mammals, humans and the environment. Initial
    product registrations can take many years to obtain, and an applicant may
    incur considerable additional delay and expense if the EPA requests
    further testing and data. To promote the development and use of
    biopesticides, the EPA has established special guidelines for their
    registration which are set out in subdivision M of the EPA's Pesticide
    Assessment Guidelines which generally require less time and expense than
    that required for synthetic pesticides.

         As a part of the pesticide registration process, the applicant must
    submit labeling data describing the chemical composition of the
    pesticide, concentrations, methods of application, pest and crop use and
    cautionary and warning statements to be put on all packaging of the
    pesticides. All pesticide packages must contain the approved label and no
    changes can be made to the label without EPA approval.

         Pesticide registrations must also be obtained from each state where
    the pesticide will be sold. Some states such as California, which
    represents an important market for the Company's products, have their own
    extensive testing and pesticide registration procedures and may impose
    additional restrictions on the use of the pesticide in such state beyond
    those imposed by the EPA regulations. Other states simply follow the EPA
    registration and labeling guidelines. The Company's products have
    received pesticide registrations in 48 states.

         Foreign countries may also require extensive testing and data
    submission before pesticides can be manufactured or sold in such foreign
    country. In many cases, foreign government regulations for submission of
    registration applications may be more extensive than EPA's regulations
    and foreign pesticide registration may be even more difficult to obtain
    than EPA approvals. Some of the Company's products are registered for
    sale in Sweden, Israel, Saudi Arabia, and Morocco.

         The Company's activities may also be subject to regulation under
    other state, federal and foreign government laws and regulations
    governing employee and public health and safety, environmental pollution,
    clean water, disposal of hazardous wastes, manufacture of chemicals,
    product liability, food and agriculture applications, and public
    disclosure of the use of chemicals.

         (ii) New Products

         Not applicable.

         (iii) Raw Materials

         Fuel and operating supplies purchased by the Company's independent
    power projects are either available from a number of different suppliers
    or from alternative sources that could be developed without a material
    adverse effect on the Company. To date, the Company has experienced no
    difficulties in obtaining these materials.

         (iv) Patents, Licenses, and Trademarks

         Not applicable.

         (v) Seasonal Influences

         The Company earns a disproportionately high share of its income in
    the months of May through October due to rate structures under the power
    sale agreements relating to its California plants, which provide strong
    incentives to operate during this period of high demand. Conversely, the
    Company historically has operated at a loss or at a marginal profit
    during its second fiscal quarter due to the rate structure under these
    agreements.

         (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

         The Company derived 10% or more of its revenues during the past
    three years from its three most significant electric utility customers:

         (x) Competition

         The worldwide independent power market now consists of numerous
    companies, ranging from small startups to multinational industrial
    companies. In addition, a number of regulated utilities have created
    subsidiaries that compete as non-utility generators. Non-utility
    generators often specialize in market "niches," such as a specific
                                       16PAGE
<PAGE>
    technology or fuel (for example, gas-fired cogeneration,
    refuse-to-energy, hydropower, geothermal, wind, solar, wood, or coal) or
    a specific region of the country where they believe they have a market
    advantage. However, many non-utility generators, seek to develop projects
    powered by the best fuel available. Many companies in this market have
    substantially greater financial, technical, and operational resources
    than the Company. The Company competes primarily on the basis of project
    experience, technical expertise, capital resources, and power pricing.
    The market in which the Company's biopesticide business competes is
    highly competitive and subject to rapid technological change. Many of the
    Company's competitors are large chemical companies with greater
    financial, marketing, and technological resources than the Company. The
    Company's biopesticide business competes primarily based on performance
    and effectiveness, and also on price, ease of application, and
    environmental impact of use.

         (xi) Research and Development

         Not applicable.

         (xii) Environmental Protection Regulation

         The construction and operation of power projects are subject to
    extensive federal, state, and local laws and regulations adopted for the
    protection of health, safety, and the environment, and to regulate land
    use. The laws and regulations applicable to the Company primarily involve
    the discharge of emissions into the water and air, and the use of water,
    but can also include wetlands preservation, endangered species, waste
    disposal, and noise regulation. These laws and regulations in many cases
    require a lengthy and complex process of obtaining licenses, permits, and
    approvals from federal, state, and local agencies. If such laws and
    regulations are changed and the Company's facilities are not
    grandfathered, extensive modifications to project technologies and
    facilities could be required.

         In November 1990, comprehensive amendments to the Clean Air Act
    were enacted. The first major revisions to the Clean Air Act since 1977,
    the 1990 Amendments expand the scope of federal regulations and
    enforcement in several significant respects. In particular, provisions
    relating to nonattainment, air toxins, permitting, enforcement, and acid
    deposition may affect many power projects. Although the majority of these
    new provisions were implemented by 1993, the full scope of the new
    requirements remains uncertain pending implementation of new regulations
    by the United States Environmental Protection Agency. The Clean Air Act
    and the 1990 Amendments contain provisions that regulate the amount of
    sulfur dioxide and nitrous oxide that may be emitted by both new and
    existing projects. None of the Company's projects are expected to be
    affected by the acid rain provisions of the 1990 Amendments. However,
    many power generating facilities may have to take various repowering
    steps to comply with the 1990 Amendments.

         The Company does not believe that it will be required to make
    material capital expenditures to comply with existing environmental
    regulations.

         (xiii) Number of Employees

         As of September 28, 1996, the Company employed, directly and
    through its Operating Companies, a total of 252 employees. None of the
    employees of the Company or the Operating Companies is represented by a
    labor union, and the Company considers its relations with its employees
    to be good.

    * John N. Hatsopoulos and George N. Hatsopoulos, a director of the

         All of the Company's executive officers are elected annually by the
    Board of Directors and serve until their successors are elected and
    qualified. All executive officers, except Messrs. Holt, Chatlosh, Gent,
    Miselis, and Nordstrom have held comparable positions for at least five
    years either with the Company or Thermo Electron. Mr. Holt has been
    President and Chief Executive Officer of the Company since February 1994,
    and a Director since January 1995. For more than five years prior to that
    time, he was President and Chief Executive Officer of Pacific Generation
    Company, a financier, builder, owner, and operator of independent power
    facilities. Mr. Chatlosh has been Vice President, Business Development
    since January 1996 and has worked for the Company in various managerial
    capacities in business development since 1993. Prior to joining the
                                       18PAGE
<PAGE>
    Company, Mr. Chatlosh worked for Oxbow Power Corporation in various
    managerial capacities in project development from 1986 to 1992. Mr. Gent
    has been Vice President, Asset Management of the Company since September
    1994. For more than five years prior to that time, Mr. Gent held various
    positions, most recently as Executive Vice President, at KTI
    Environmental Group, a developer, owner, and operator of waste-to-energy
    plants. Mr. Miselis has been Vice President of Accounting and
    Administration since January 1996 and has worked for the Company in
    various accounting capacities since November 1988. Mr. Nordstrom has been
    Vice President of Business Development, Asia, since January 1996 and has
    worked for the Company in various managerial capacities within marketing,
    project development, and operations since 1984. Messrs. Hatsopoulos and
    Kelleher are full-time employees of Thermo Electron, but devote such time
    to the affairs of the Company as the Company's needs reasonably require.


    Item 2. Properties

         The Company's corporate headquarters are located in Waltham,
    Massachusetts and consist of approximately 15,000 square feet that are
    occupied pursuant to a lease expiring in 2003. The Company also leases
    office space in Columbia, Maryland; Calcutta, India; Bangalore, India;
    Prague, Czech Republic; and Roseville, California. The Company's other
    properties consist of the power plants described under "Operating
    Projects." The Company owns all of the land on which the plants are
    built. In addition, the Company's Thermo Trilogy subsidiary leases
    warehouse space in Fresno, California.

         The Company's California plants are located in areas where there is
    a risk of potentially significant earthquake activity. Projects that the
    Company develops in the future may also be located in areas, including
    India, where there is earthquake risk. The Company's earthquake insurance
    is not sufficient to cover all potential losses and there can be no
    assurance that such insurance will continue to be available on reasonable
    terms.

                    Report of Independent Public Accountants


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

         We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Thermo
    Ecotek 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 22 is the responsibility of the Company's management and is
    presented for the 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.

                            TAX ALLOCATION AGREEMENT


             THIS AMENDED AND RESTATED AGREEMENT is made as of December
        4, 1996 between Thermo Electron Corporation, a Delaware
        corporation ("Thermo Electron"), and Thermo Ecotek Corporation, a
        Delaware corporation ("Ecotek").


                              Preliminary Statement


             Thermo Electron is the parent of an affiliated group of
        corporations (including Ecotek) within the meaning of Section
        1504(a) of the Internal Revenue Code of 1986, as amended (the
        "Code").

             Thermo Electron owns over 80% of the issued and outstanding
        shares of voting common stock of Ecotek, the only class of stock
        that Ecotek is authorized to issue.     Ecotek is required to
        file consolidated federal income tax returns with Thermo
        Electron.

             Thermo Electron, as the common parent of an affiliated group
        of corporations, and Ecotek recognize that any one of them that
        sustains a net operating loss or otherwise generates beneficial
        tax attributes for a taxable period may be deprived of such
        benefits when offset in that or other periods against income or
        tax liabilities of the others.


                                   Agreements


             IT IS MUTUALLY agreed by the parties hereto as follows:

             1.   Definitions and Construction.

                  1.1  The Term "Thermo Electron Group" means the group
        of corporations of which Thermo Electron is common parent and
        with which Thermo Electron files a consolidated federal income
        tax return, excluding Ecotek and subsidiaries of Ecotek that may
        exist now or in the future.  For purposes of this Agreement, the
        Thermo Electron Group shall be treated as a single corporate
        entity.  The Thermo Electron Group and Ecotek and its
        subsidiaries, respectively, are sometimes herein referred to
        collectively as the "Two Companies" or the "Companies."  The term
        "Deficit Company" means either one of the Companies that has an
        ordinary loss, capital loss, special deduction or tax credit
        arising in a consolidated return year, or in a prior separate
        return year, that is utilized to a greater extent in the then
        current consolidated federal income tax return than would have
PAGE
<PAGE>
        been the case if the Company had filed a separate federal income
        tax return for the year.  This Agreement anticipates that Thermo
        Electron will set aside and retain certain sums calculated as
        provided herein.  All reference to Thermo Electron paying sums to
        itself pursuant to this Agreement shall be satisfied by Thermo
        Electron setting aside sums in respect of the obligations
        established under this Agreement.

                  1.2  The paragraph titles used herein are for
        convenience of reference only and will not be considered in the
        interpretation or construction of any of the provisions hereof.
        Words may be construed in the singular or the plural as the
        context requires.

             2.   Tax Returns.

                  2.1  Federal Tax Returns.  Thermo Electron as the
        common parent will prepare and file or cause to be prepared and
        filed federal and state income tax returns on a consolidated
        basis, for the Thermo Electron Group and Ecotek and its
        subsidiaries for all fiscal periods as to which a  consolidated
        return is appropriate in accordance with the terms of this
        Agreement.

                  2.2  State Tax Returns.  Thermo Electron as the common
        parent will prepare and file or cause to be filed state income
        tax returns on a combined, consolidated, unitary, or other method
        that Thermo Electron believes will result in a lower overall tax
        liability to the Two Companies.  Ecotek will reimburse Thermo
        Electron for its portion of the tax.  Such reimbursement will be
        the tax Ecotek would have paid on a separate return basis, but
        only if it was required to file a return in that state.

             3.   Time of Payment of Federal Obligations to Thermo
        Electron.  The obligations of the Companies for Federal income
        tax payments will be determined and paid as follows:

                  (a)  Not later than the 15th day after the end of the
        fourth, sixth, ninth and twelfth months of each consolidated
        taxable year of Thermo Electron, Thermo Electron will make a
        reasonable determination (consistent with the provisions of
        Section 6655 of the Code) of the separate federal income tax
        liability that each Company would be required to pay as estimated
        payments on a separate return basis (without regard to
        alternative minimum tax) for that period.  Each Company shall pay
        to Thermo Electron the amount of such liability within ten days.

                  (b)  After the end of Thermo Electron's fourth
        accounting quarter and before the 15th day of the third month
        thereafter, each Company will promptly pay to Thermo Electron the
        entire amounts estimated to be due and payable under such
        Company's federal income tax return as if filed on a separate
        return basis, less all amounts previously paid with respect to
        that year pursuant to subparagraph (a) of this Paragraph 3.
PAGE
<PAGE>
                  (c)  If upon the filing of the consolidated income tax
        return, a revised calculation is made in the manner set forth in
        subparagraph (b) of this Paragraph 3, and it is determined that
        either Company has paid to Thermo Electron with respect to the
        consolidated taxable year an amount greater than that required by
        Paragraph 3(b), then that excess will be promptly paid by Thermo
        Electron to that Company.

             4.   Tax Obligations of Thermo Electron.  Thermo Electron
        will pay the consolidated tax liabilities of the Companies
        arising from filing a consolidated federal tax return.

             5.   Payment of Funds by Thermo Electron. If in any year
        Ecotek incurs a loss or generates tax credits or similar tax
        benefits (a "tax benefit item"), Thermo Electron shall pay to
        Ecotek a sum equal to the amount of benefit realized by Thermo
        Electron that is attributable to the  Ecotek tax benefit item;
        payments due to Ecotek from Thermo Electron under this section
        shall be made upon the earlier of (1) the year in which Ecotek
        would have obtained a tax benefit from the tax benefit item if
        Ecotek had in all years filed a separate federal income tax
        return or (2) the year in which any applicable carry-forward
        period with respect to the tax benefit item expires; provided
        that payments under this section shall be made first by being
        taken into account in determining amounts payable to Ecotek under
        Section 3, and any remaining amount due to Ecotek shall be paid
        by Thermo Electron to Ecotek at the times set forth for payments
        by Ecotek under Section 3.

             6.   Changes in Prior Year's Tax Liabilities.  In the event
        that the consolidated tax liability or the separate tax liability
        referred to in Paragraphs 3 and 5 hereof for any year for which a
        consolidated tax return for the two Companies was filed is or
        would be increased or decreased by reason of filing an amended
        return or returns (including carry-back claims), or by reason of
        the examination of the returns by the Internal Revenue Service,
        the amounts due Thermo Electron for payment of taxes under
        Paragraph 3 hereof, and the amount to be paid to Thermo Electron
        for allocation to Ecotek under Paragraph 5 hereof for each year
        will be recomputed by Thermo Electron to reflect the adjustments
        to taxable income and tax credits for the taxable year and
        interest or penalties, if any.  In accordance with those
        recomputations, additional sums will be paid by the Companies to
        Thermo Electron or paid by Thermo Electron to the Companies
        regardless of whether a member has become a Departing Member (as
        defined in Paragraph 8 hereof) subsequent to the taxable year of
        recomputation.

             7.   New Members.  The Companies agree that if, subsequent
        to the execution of this Agreement, Thermo Electron becomes the
        Parent, as that term is used in Section 1504 of the Code, of one
        or more subsidiary corporations, ion addition to Ecotek, then
        each newly-acquired subsidiary corporation may become a separate
PAGE
<PAGE>
        party to this Agreement by consenting in writing to be bound by
        its provisions, effective immediately upon its delivery to Thermo
        Electron, but the income, deductions and tax credits of the
        newly-acquired subsidiary corporations will first be included in
        the consolidated federal income tax return as required by the
        Code.

             8.   Departing Members.

                  8.1  The term "Departing Members," as used herein, will
        mean a Company that is no longer permitted under the Code to be
        included in the consolidated federal income tax return.

                  8.2  In applying this Agreement to a Departing Member
        for the final taxable year in which its income, deductions, and
        tax credits are required to be included in the consolidated
        federal income tax return:  (i) the amount required to be paid by
        a Departing Member under the provisions of Paragraph 3 hereof and
        (ii) the amount that the Departing Member is entitled to receive
        under the provisions of Paragraph 5 hereof, will be determined by
        taking into account the income, deductions and tax credits of the
        Departing Member only for the fractional part of such year as the
        Departing Member was a member of the consolidated group and
        included in the consolidated federal income tax return.

                  8.3  After the filing of the consolidated federal
        income tax return for the last taxable year that the Departing
        Member was included therein, the Departing Member will be
        informed of the amount of consolidated carry-overs as of the end
        of the taxable year or period which are attributable to the
        Departing Member, as provided by Treasury Regulations Section
        1.1502-79 or otherwise, including the agreement of the parties.

             9.   Determination of Sums Due from and Payable to Members.
        Thermo Electron will determine the sums due from and payable to
        the Companies under the provisions of this Agreement (including
        the determination for purposes of Paragraph 6 hereof).  The
        Companies agree to provide Thermo Electron with such information
        as may reasonably be necessary to make these determinations.
        Issues arising in the course of the determinations that are not
        expressly provided for in this agreement will be resolved in an
        equitable manner.

             10.  Tax Controversies.  If a consolidated federal income
        tax return for any taxable year during which this Agreement is in
        effect is examined by the Internal Revenue Service, the
        examination, as well as any other matters relating to that tax
        return, including any tax litigation, will be handled solely by
        Thermo Electron.  Ecotek will cooperate with Thermo Electron and
        to this end will execute protests, petitions, and any other
        documents as Thermo Electron determines to be necessary or
        appropriate.  The cost and expense of Thermo Electron's handling
        of a tax controversy, including legal and accounting fees, will
        be allocated to and paid by the Company to whom the tax
PAGE
<PAGE>
        controversy relates.  If the tax controversy relates to both
        Companies, the cost and expense will be allocated between the
        Companies in the proportion that each Company's potential
        additional tax liability bears to the total potential additional
        tax liability of both Companies (determined in accordance with
        Paragraph 6 hereto and assuming that the tax controversy is
        resolved in favor of the Internal Revenue Service) for the
        taxable year on issue.  If the tax controversy encompasses more
        than one taxable year, Thermo Electron will first allocate the
        cost and expense to each taxable year in the proportion that the
        potential additional tax liability for each taxable year bears to
        the total potential additional tax liability for the taxable
        years in issue.

             11.  Effective Date.  This Agreement shall be effective
        beginning as of the date of this Agreement, and will continue on
        a year-to-year basis thereafter with respect to Ecotek for so
        long as Ecotek is permitted to file a consolidated federal income
        tax return with Thermo Electron.

             12.  State Taxes.  The two Companies will jointly file any
        state tax return on a combined, consolidated, unitary, or other
        method that Thermo Electron determines results in a lower overall
        tax liability to the Two Companies.  In the event that said state
        tax returns shall be filed, the provisions of Sections 1-11
        hereof shall apply, mutatis mutandis (the necessary changes being
        made) to the allocation, preparation, filing and payment related
        to such state taxes and tax returns provided, however, that any
        benefit realized by the filing of the combined, consolidated or
        unitary return will remain with Thermo Electron.

             IN WITNESS WHEREOF,  the parties hereto have caused this
        Agreement to be executed by their duly authorized officers as of
        the date first above written.

                                                            Exhibit 10.51
                            THERMO ECOTEK CORPORATION

                  THERMO TRILOGY NONQUALIFIED STOCK OPTION PLAN


        1.   Purpose

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

        2.   Effective Date of the Plan

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

        3.   Stock Subject to Plan

             At no time shall  the number of shares  of the Common  Stock
        then outstanding  which  are  attributable  to  the  exercise  of
        options granted under  the Plan  plus the number  of shares  then
        issuable upon the exercise  of outstanding options granted  under
        the Plan  exceed  1500,000 shares,   subject    however to the
        provisions of paragraph 11 of the Plan.  Shares to be issued upon
        the exercise of options granted under the Plan shall be shares of
        Subsidiary beneficially  owned by  the Company.   If  any  option
        expires  or  terminates  for  any  reason  without  having   been
        exercised in full, the  unpurchased shares subject thereto  shall
        again be available for options thereafter to be granted.

        4.   Administration

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

        5.   Eligibility

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

        6.   Time of Granting Options

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

        7.   Option Period

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

        8.   Exercise of Option

             An option may be exercised  in accordance with its terms  by
        written notice of intent to  exercise the option, specifying  the
        number of shares  of stock with  respect to which  the option  is
        then being exercised.  The notice shall be accompanied by payment
        in the form  of cash or  shares of Subsidiary  Common Stock  (the
        "Tendered Shares") with a then current market value equal to  the
        option price of  the shares to  be purchased; provided,  however,
PAGE
<PAGE>
        that such  Tendered  Shares  shall  have  been  acquired  by  the
        Optionee more  than six  months prior  to the  date of  exercise,
        unless such  requirement is  waived in  writing by  the  Company.
        Against such payment  the Company  shall deliver or  cause to  be
        delivered to the Optionee a certificate for the number of  shares
        then being purchased, registered in  the name of the Optionee  or
        other person exercising  the option.   If any  law or  applicable
        regulation of  the Securities  and Exchange  Commission or  other
        body having  jurisdiction  in  the  premises  shall  require  the
        Company, Subsidiary  or  the  Optionee  to  take  any  action  in
        connection with  shares  being  purchased upon  exercise  of  the
        option, exercise of the option and delivery of the certificate or
        certificates for such shares shall be postponed until  completion
        of the necessary action,  which shall be  taken at the  Company's
        expense.

        9.   Transferability

             Options shall not be transferable, otherwise than by will or
        the laws of descent and distribution, except as may be authorized
        by the Committee, in its  sole discretion. T he Committee may, in
        its discretion, determine the extent to which options granted  to
        an Optionee shall be transferable, and such provisions permitting
        transfer shall  be  set forth  in  the written  option  agreement
        executed and delivered  by or on  behalf of the  Company and  the
        Optionee.

        10.  Vesting, Restrictions and Termination of Options

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

        11.  Adjustment of Number of Shares

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

        12.  Limitation of Rights in Option Stock

             The Optionees  shall  have  no  rights  as  stockholders  in
        respect of shares as to which  their options shall not have  been
        exercised, certificates  issued  and  delivered  and  payment  as
        herein provided  made in  full,  and shall  have no  rights  with
        respect to such shares not expressly conferred by this Plan.

        13.  Stock Reserved
PAGE
<PAGE>
             The Company  shall  at all  times  during the  term  of  the
        options reserve and keep available  such number of shares of  the
        Common Stock as will be sufficient to satisfy the requirements of
        this Plan and shall pay  all other fees and expenses  necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

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

        15.  Tax Withholding

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

        16.  Termination and Amendment of Plan

             The Board of  Directors may at  any time, and  from time  to
        time, modify or amend the Plan in any respect.

             Notwithstanding any other provisions hereof, the Plan  shall
        terminate on December 31,  2006 and no  options shall be  granted
        hereunder thereafter.



                                                           Exhibit 10.52
                           THERMO TRILOGY CORPORATION

                              EQUITY INCENTIVE PLAN


        1.   Purpose

             The purpose of this Equity Incentive Plan (the "Plan") is to
        secure for  Thermo  Trilogy Corporation (the "Company")  and  its
        Stockholders the benefits arising from capital stock ownership by
        employees, officers  and Directors  of, and  consultants to,  the
        Company and its subsidiaries or other persons who are expected to
        make significant contributions to  the future growth and  success
        of the Company  and its subsidiaries.   The Plan  is intended  to
        accomplish these  goals by  enabling the  Company to  offer  such
        persons  equity-based  interests,   equity-based  incentives   or
        performance-based  stock  incentives  in  the  Company,  or   any
        combination thereof ("Awards").

        2.   Administration

             The Plan will be administered  by the Board of Directors  of
        the Company (the "Board").   The Board shall  have full power  to
        interpret and  administer  the  Plan,  to  prescribe,  amend  and
        rescind rules and  regulations relating to  the Plan and  Awards,
        and full authority to select the  persons to whom Awards will  be
        granted ("Participants"), determine the type and amount of Awards
        to be  granted  to  Participants (including  any  combination  of
        Awards), determine  the terms  and conditions  of Awards  granted
        under the Plan (including terms and conditions relating to events
        of merger, consolidation, dissolution and liquidation, change  of
        control,  vesting,   forfeiture,  restrictions,   dividends   and
        interest, if any,  on deferred  amounts), waive  compliance by  a
        participant with any  obligation to  be performed by  him or  her
        under an Award, waive any term  or condition of an Award,  cancel
        an existing  Award in  whole or  in part  with the  consent of  a
        Participant, grant replacement Awards, accelerate the vesting  or
        lapse of any  restrictions of  any Award  and adopt  the form  of
        instruments evidencing  Awards under  the  Plan and  change  such
        forms from time to time.  Any interpretation by the Board of  the
        terms and provisions of the Plan or any Award thereunder and  the
        administration thereof, and all action taken by the Board,  shall
        be final, binding and  conclusive on all  parties and any  person
        claiming under or through any party.  No Director shall be liable
        for any action or  determination made in good  faith.  The  Board
        may, to the full extent permitted by law, delegate any or all  of
        its  responsibilities  under  the   Plan  to  a  committee   (the
        "Committee") appointed by the Board and consisting of two or more
        members  of  the  Board,   each  of  whom   shall  be  deemed   a
        "disinterested person" within the meaning  of Rule 16b-3 (or  any
        successor rule)  of  the Securities  Exchange  Act of  1934  (the
        "Exchange Act").  

        3.   Effective Date
PAGE
<PAGE>
                                        2

             The Plan shall be effective as of the date first approved by
        the Board of Directors.  

        4.   Shares Subject to the Plan

             Subject to adjustment as provided in Section 10.6, the total
        number of shares of the common  stock, $.01 par value per  share,
        of the Company (the "Common  Stock"), reserved and available  for
        distribution under  the Plan  shall  be 600,000    shares.   Such
        shares may  consist,  in whole  or  in part,  of  authorized  and
        unissued shares or treasury shares.

             If any Award of shares of Common Stock requiring exercise by
        the Participant for  delivery of such  shares terminates  without
        having been  exercised  in full,  is  forfeited or  is  otherwise
        terminated without a payment being made to the Participant in the
        form of Common Stock, or if any shares of Common Stock subject to
        restrictions are repurchased by the Company pursuant to the terms
        of any  Award  or are  otherwise  reacquired by  the  Company  to
        satisfy obligations arising by virtue  of any Award, such  shares
        shall be  available for  distribution in  connection with  future
        Awards under the Plan.

                                        3

        5.   Eligibility

             Employees, officers and  Directors of,  and consultants  to,
        the Company  and  its  subsidiaries, or  other  persons  who  are
        expected to make significant  contributions to the future  growth
        and success of the Company and its subsidiaries shall be eligible
        to  receive  Awards  under  the  Plan.    The  Board,  or   other
        appropriate committee or person to the extent permitted  pursuant
        to the last sentence of Section 2, shall from time to time select
        from among such  eligible persons those  who will receive  Awards
        under the Plan.

        6.   Types of Awards

             The Board may  offer Awards under  the Plan in  any form  of
        equity-based     interest,     equity-based     incentive      or
        performance-based stock incentive in Common Stock of the  Company
        or any combination thereof.   The type, terms and conditions  and
        restrictions of an Award shall be determined by the Board at  the
        time such Award is made  to a Participant; provided however  that
        the maximum number of  shares permitted to  be granted under  any
        Award or combination of Awards to any Participant during any  one
        calendar year  may  not exceed 5% of  the shares of Common  Stock
        outstanding at the beginning of such calendar year.

             An Award shall be  made at the time  specified by the  Board
        and shall be subject to such conditions or restrictions as may be
        imposed by  the Board  and  shall conform  to the  general  rules
        applicable under  the Plan  as  well as  any special  rules  then
        applicable under federal tax laws  or regulations or the  federal
        securities laws relating to the type of Award granted.

             Without  limiting  the  foregoing,   Awards  may  take   the
        following forms and shall be  subject to the following rules  and
        conditions:

             6.1  Options

             An option is an Award  that entitles the holder on  exercise
        thereof to purchase Common Stock  at a specified exercise  price.
        Options granted  under the  Plan may  be either  incentive  stock
        options ("incentive stock options") that meet the requirements of
        Section 422 of the Internal Revenue Code of 1986, as amended (the
        "Code"),  or  options   that  are  not   intended  to  meet   the
        requirements of Section 422 ("non-statutory options").

             6.1.1     Option Price.  The price at which Common Stock may
        be purchased upon exercise  of an option  shall be determined  by
        the Board, provided however, the exercise price shall not be less
        than the par value per share of Common Stock.  

             6.1.2     Option Grants .  The  granting of an  option shall
        take place at the time specified by the Board.  Options shall  be
        evidenced by option agreements.  Such agreements shall conform to
PAGE
<PAGE>
                                        4
        the  requirements  of  the  Plan,  and  may  contain  such  other
        provisions (including but not  limited to vesting and  forfeiture
        provisions, acceleration, change  of control,  protection in  the
        event of merger,  consolidations, dissolutions and  liquidations)
        as the  Board  shall deem  advisable.   Option  agreements  shall
        expressly state whether an option grant is intended to qualify as
        an incentive stock option or non-statutory option.

             6.1.3     Option Period .  An option will become exercisable
        at such  time or  times  (which may  be  immediately or  in  such
        installments as the Board shall determine) and on such terms  and
        conditions as the  Board shall  specify.   The option  agreements
        shall specify the terms and conditions applicable in the event of
        an option holder's termination of employment during the  option's
        term.

             Any exercise of an option must be in writing, signed by  the
        proper person and delivered or mailed to the Company, accompanied
        by (1) any  additional documents  required by the  Board and  (2)
        payment in full in accordance  with Section 6.1.4 for the  number
        of shares for which the option is exercised.

             6.1.4     Payment of  Exercise Price.    Stock purchased  on
        exercise of an option shall be paid for as follows:  (1) in  cash
        or by  check  (subject to  such  guidelines as  the  Company  may
        establish for this purpose), bank draft or money order payable to
        the order of the Company or (2) if so permitted by the instrument
        evidencing the option (or in the case of a non-statutory  option,
        by the Board at  or after grant of  the option), (i) through  the
        delivery of shares of Common Stock that have been outstanding for
        at least  six  months  (unless the  Board  expressly  approves  a
        shorter period) and that have a fair market value (determined  in
        accordance with procedures prescribed by the Board) equal to  the
        exercise price,  (ii) by  delivery of  a promissory  note of  the
        option holder  to  the Company,  payable  on such  terms  as  are
        specified by the Board, (iii) by delivery of an unconditional and
        irrevocable undertaking by  a broker to  deliver promptly to  the
        Company sufficient funds to  pay the exercise  price, or (iv)  by
        any combination of the permissible forms of payment.

             6.1.5     Buyout Provision.  The Board may at any time offer
        to buy  out  for a  payment  in  cash, shares  of  Common  Stock,
        deferred stock or restricted stock, an option previously granted,
        based on such terms and  conditions as the Board shall  establish
        and communicate to the option holder at the time that such  offer
        is made.

             6.1.6     Special Rules for Incentive  Stock Options.  Each
        provision of the  Plan and  each option  agreement evidencing  an
        incentive stock option shall be construed so that each  incentive
        stock option shall  be an  incentive stock option  as defined  in
        Section 422  of  the Code  or  any statutory  provision that  may
        replace such Section, and any  provisions thereof that cannot  be
        so  construed  shall  be  disregarded.    Instruments  evidencing
PAGE
<PAGE>
                                        5

        incentive stock  options  must  contain such  provisions  as  are
        required under  applicable provisions  of  the Code.    Incentive
        stock options may be granted only to employees of the Company and
        its subsidiaries.    The exercise  price  of an  incentive  stock
        option shall  not be  less than  100%  (110% in  the case  of  an
        incentive stock  option  granted  to  a  more  than  ten  percent
        Stockholder of  the Company)  of  the fair  market value  of  the
        Common Stock on the  date of grant, as  determined by the  Board.
        An incentive  stock option  may not  be granted  after the  tenth
        anniversary of the  date on  which the  Plan was  adopted by  the
        Board and the latest date on which an incentive stock option  may
        be exercised shall be  the tenth anniversary (fifth  anniversary,
        in the case of any incentive stock option granted to a more  than
        ten percent Stockholder of the Company) of the date of grant,  as
        determined by the Board.

             6.2  Restricted and Unrestricted Stock

             An Award of restricted stock entitles the recipient  thereof
        to acquire shares of  Common Stock upon  payment of the  purchase
        price  subject  to  restrictions  specified  in  the   instrument
        evidencing the Award.

             6.2.1     Restricted Stock  Awards .   Awards  of restricted
        stock shall be  evidenced by restricted  stock agreements.   Such
        agreements shall conform to the requirements of the Plan, and may
        contain  such   other  provisions   (including  restriction   and
        forfeiture provisions, change of control, protection in the event
        of mergers, consolidations, dissolutions and liquidations) as the
        Board shall deem advisable.

             6.2.2     Restrictions.  Until the restrictions specified in
        a restricted stock  agreement shall lapse,  restricted stock  may
        not  be  sold,  assigned,   transferred,  pledged  or   otherwise
        encumbered or disposed of, and upon certain conditions  specified
        in the restricted stock agreement, must be resold to the  Company
        for the  price,  if  any,  specified  in  such  agreement.    The
        restrictions shall  lapse at  such  time or  times, and  on  such
        conditions, as the Board may specify.  The Board may at any  time
        accelerate the time at which the restrictions on all or any  part
        of the shares shall lapse.

             6.2.3     Rights  as  a  Stockholder.    A  Participant  who
        acquires shares of restricted stock  will have all of the  rights
        of a Stockholder with respect to such shares including the  right
        to receive dividends and to vote  such shares.  Unless the  Board
        otherwise   determines,   certificates   evidencing   shares   of
        restricted stock will  remain in  the possession  of the  Company
        until such shares are free of all restrictions under the Plan.

             6.2.4     Purchase Price  . The purchase  price of shares of
        restricted stock shall be  determined by the  Board, in its  sole
        discretion, but such price may not be less than the par value  of
        such shares.
PAGE
<PAGE>
                                        6

             6.2.5     Other Awards Settled With  Restricted Stock .  The
        Board may  provide that  any or  all the  Common Stock  delivered
        pursuant to an Award will be restricted stock.
          
             6.2.6     Unrestricted Stock.   The  Board may, in  its sole
        discretion, sell to any Participant  shares of Common Stock  free
        of restrictions  under the  Plan for  a price  determined by  the
        Board, but which may not be less than the par value per share  of
        the Common Stock.

             6.3  Deferred Stock

             6.3.1     Deferred Stock  Award  .  A  deferred stock  Award
        entitles the recipient to receive shares of deferred stock  which
        is Common Stock to be delivered  in the future.  Delivery of  the
        Common Stock will take place at  such time or times, and on  such
        conditions, as the Board may specify.  The Board may at any  time
        accelerate the time at which delivery  of all or any part of  the
        Common Stock will take place.

             6.3.2     Other Awards  Settled with  Deferred Stock.    The
        Board may, at the time any  Award described in this Section 6  is
        granted, provide that, at the  time Common Stock would  otherwise
        be delivered pursuant to the Award, the Participant will  instead
        receive an instrument evidencing the right to future delivery  of
        deferred stock.

             6.4  Performance Awards

             6.4.1     Performance Awards .  A performance Award entitles
        the recipient to receive, without payment, an Amount, in cash  or
        Common Stock or a combination thereof (such form to be determined
        by the  Board), following  the attainment  of performance  goals.
        Performance  goals  may  be  related  to  personal   performance,
        corporate performance,  departmental  performance  or  any  other
        category of performance deemed  by the Board  to be important  to
        the success  of  the  Company.   The  Board  will  determine  the
        performance goals, the period or periods during which performance
        is to be measured and  all other terms and conditions  applicable
        to the Award.

             6.4.2     Other Awards  Subject to  Performance  Conditions.
        The Board may, at the time any Award described in this Section  6
        is granted, impose the condition  (in addition to any  conditions
        specified or  authorized in  this  Section 6  of the  Plan)  that
        performance goals be met  prior to the Participant's  realization
        of any payment or benefit under the Award.

        7.   Purchase Price and Payment

             Except as otherwise provided in the Plan, the purchase price
        of Common Stock to be acquired pursuant to an Award shall be  the
        price determined by the Board, provided that such price shall not
        be less than  the par  value of  the Common  Stock.    Except  as
PAGE

                                        7

        otherwise provided  in  the Plan,  the  Board may  determine  the
        method of payment of the exercise  price or purchase price of  an
        Award granted under the Plan and the form of payment.  The  Board
        may determine  that all  or any  part of  the purchase  price  of
        Common Stock  pursuant to  an Award  has been  satisfied by  past
        services rendered by the Participant.  The Board may agree at any
        time, upon request of the Participant, to defer the date on which
        any payment under an Award will be made.

        8.   Loans and Supplemental Grants

             The Company may make a loan  to a Participant, either on  or
        after the grant to  the Participant of  any Award, in  connection
        with the purchase  of Common Stock  under the Award  or with  the
        payment of any obligation incurred  or recognized as a result  of
        the Award.  The Board will have full authority to decide  whether
        the loan  is  to be  secured  or  unsecured or  with  or  without
        recourse against the borrower, the terms on which the loan is  to
        be repaid  and the  conditions, if  any, under  which it  may  be
        forgiven.

             In connection with any Award, the Board may at the time such
        Award is made or  at a later  date, provide for  and make a  cash
        payment to the participant not to  exceed an amount equal to  (a)
        the amount of any federal, state and local income tax or ordinary
        income for which the Participant  will be liable with respect  to
        the Award, plus (b)  an additional amount  on a grossed-up  basis
        necessary to make him or her whole after tax, discharging all the
        participant's income tax  liabilities arising  from all  payments
        under the Plan.

        9.   Change in Control

             9.1  Impact of Event

             In the event of a "Change in Control" as defined in  Section
        9.2, the following provisions  shall apply, unless the  agreement
        evidencing the Award otherwise provides:

             (a) Any stock  options or other  stock-based Awards  awarded
             under the  Plan that  were  not previously  exercisable  and
             vested shall become fully exercisable and vested.

             (b) Awards of restricted stock and other stock-based  Awards
             subject to restrictions and to the extent not fully  vested,
             shall become fully  vested and all  such restrictions  shall
             lapse so that shares issued pursuant to such Awards shall be
             free of restrictions.

             (c) Deferral limitations and  conditions that relate  solely
             to the passage of time, continued employment or affiliation,
             will be waived and removed  as to deferred stock Awards  and
             performance Awards.  Performance of other conditions  (other
             than conditions  relating solely  to  the passage  of  time,

                                        8

             continued employment or affiliation) will continue to  apply
             unless otherwise provided  in the  agreement evidencing  the
             Awards or in any other agreement between the Participant and
             the Company or unless otherwise agreed by the Board.

        the Prior  Directors to  constitute a  majority of  the Board  of
        Directors of the  Company, Thermo Ecotek  or Thermo Electron,  as
        the case  may be,  at any  time within  two years  following  any
        Electoral  Event,  or  (iii)  any  other  event  that  the  Prior
        Directors shall determine constitutes an effective change in  the

             term is defined in Rule 405 under the Securities Act of 1933
             and any "group"  (within the  meaning of such  term in  Rule
             13d-5 under the Exchange Act);

             (b) "Prior Directors" shall mean the persons sitting on  the

        10.  General Provisions

             10.1 Documentation of Awards

             Awards will be evidenced  by written instruments, which  may
        differ among Participants, prescribed by  the Board from time  to
        time.  Such instruments  may be in the  form of agreements to  be
        executed by both the Participant and the Company or certificates,
        letters or similar instruments which need not be executed by  the
        participant but acceptance  of which will  evidence agreement  to
        the terms  thereof.    Such  instruments  shall  conform  to  the
        requirements of the  Plan and may  contain such other  provisions
        (including   provisions   relating    to   events   of    merger,
        consolidation, dissolution  and liquidations,  change of  control
        and restrictions  affecting either  the agreement  or the  Common
        Stock issued thereunder), as the Board deems advisable.

             10.2 Rights as a Stockholder

             Except  as  specifically  provided   by  the  Plan  or   the
        instrument evidencing the Award, the receipt of an Award will not
        give a Participant rights  as a Stockholder  with respect to  any
        shares covered by  an Award until  the date of  issue of a  stock
        certificate to the participant for such shares.

             10.3 Conditions on Delivery of Stock

             The Company will not be  obligated to deliver any shares  of
        Common Stock pursuant to  the Plan or  to remove any  restriction
        from shares previously  delivered under  the Plan  (a) until  all
        conditions of  the  Award have  been  satisfied or  removed,  (b)
        until, in the  opinion of the  Company's counsel, all  applicable
        federal and state laws and  regulations have been complied  with,
        (c) if the outstanding Common Stock is at the time listed on  any
        stock exchange, until the shares  have been listed or  authorized
        to be listed on such  exchange upon official notice of  issuance,
        and (d)  until all  other legal  matters in  connection with  the
        issuance and delivery of  such shares have  been approved by  the
        Company's counsel.   If the  sale of  Common Stock  has not  been
        registered under  the Securities  Act of  1933, as  amended,  the
        Company may require,  as a  condition to exercise  of the  Award,
        such representations or agreements as counsel for the Company may
        consider appropriate  to  avoid violation  of  such act  and  may
        require that the certificates  evidencing such Common Stock  bear
        an appropriate legend restricting transfer.

             If  an  Award  is  exercised  by  the  participant's   legal
        representative, the  Company  will  be  under  no  obligation  to
        deliver Common Stock pursuant to such exercise until the  Company
        is satisfied as to the authority of such representative.

             10.4 Tax Withholding
PAGE
<PAGE>
                                       10

             The  Company  will  withhold  from  any  cash  payment  made
        pursuant to an Award an amount sufficient to satisfy all federal,
        state and local  withholding tax  requirements (the  "withholding
        requirements").

             In the case of an Award  pursuant to which Common Stock  may
        be delivered, the Board will have  the right to require that  the
        participant or other appropriate person  remit to the Company  an
        amount sufficient  to satisfy  the withholding  requirements,  or
        make other arrangements satisfactory to the Board with regard  to
        such requirements, prior to the delivery of any Common Stock.  If
        and to the extent  that such withholding  is required, the  Board
        may permit the participant or such other person to elect at  such
        time and in such manner as the Board provides to have the Company
        hold back from the shares to  be delivered, or to deliver to  the
        Company, Common Stock  having a value  calculated to satisfy  the
        withholding requirement.

             10.5 Nontransferability of Awards

             Options shall not be transferable, otherwise than by will or
        the laws of descent and distribution, except as may be authorized
        by the Committee, in its  sole discretion. T he Committee may, in
        its discretion, determine the extent to which options granted  to
        an Optionee shall be transferable, and such provisions permitting
        transfer shall  be  set forth  in  the written  option  agreement
        executed and delivered  by or on  behalf of the  Company and  the
        Optionee.

             10.6 Adjustments in the Event of Certain Transactions

             (a)   In the  event  of a  stock  dividend, stock  split  or
        combination of shares,  recapitalization or other  change in  the
        Company's capitalization, or other  distribution with respect  to
        common Stockholders other than  normal cash dividends, the  Board
        will make (i)  appropriate adjustments to  the maximum number  of
        shares that  may be  delivered  under the  Plan under  Section  4
        above, and (ii) appropriate adjustments to the number and kind of
        shares of stock or securities subject to Awards then  outstanding
        or subsequently granted, any  exercise prices relating to  Awards
        and any other provisions of Awards affected by such change.

             (b)  The Board may also make appropriate adjustments to take
        into account material changes in  law or in accounting  practices
        or    principles,    mergers,    consolidations,    acquisitions,
        dispositions, repurchases or  similar corporate transactions,  or
        any  other  event,  if  it  is  determined  by  the  Board   that
        adjustments are appropriate to avoid distortion in the  operation
        of the Plan, but no such adjustments other than those required by
        law may adversely affect the  rights of any Participant  (without
        the Participant's consent) under any Award previously granted.

             10.7 Employment Rights
PAGE
<PAGE>
                                       11

             Neither the adoption  of the  Plan nor the  grant of  Awards
        will confer upon  any person  any right  to continued  employment
        with the Company or any subsidiary  or interfere in any way  with
        the  right  of  the  Company  or  subsidiary  to  terminate   any
        employment relationship at  any time or  to increase or  decrease
        the compensation of such person.  Except as specifically provided
        by the Board  in any  particular case,  the loss  of existing  or
        potential profit  in  Awards  granted under  the  Plan  will  not
        constitute an element of damages  in the event of termination  of
        an  employment  relationship  even  if  the  termination  is   in
        violation of an obligation of the Company to the employee.

             Whether an  authorized  leave  of  absence,  or  absence  in
        military or government service,  shall constitute termination  of
        employment shall be  determined by the  Board at the  time.   For
        purposes of this Plan, transfer of employment between the Company
        and  its  subsidiaries  shall   not  be  deemed  termination   of
        employment.

             10.8 Other Employee Benefits

             The value of  an Award granted  to a Participant  who is  an
        employee, and  the  amount  of  any  compensation  deemed  to  be
        received by an employee as a  result of any exercise or  purchase
        of Common Stock pursuant to an  Award or sale of shares  received
        under the Plan, will not constitute "earnings" or  "compensation"
        with respect  to  which  any  other  employee  benefits  of  such
        employee are  determined, including  without limitation  benefits
        under  any  pension,  stock   ownership,  stock  purchase,   life
        insurance, medical,  health,  disability or  salary  continuation
        plan.

             10.9 Legal Holidays

             If any day on or before which action under the Plan must  be
        taken falls on a Saturday,  Sunday or legal holiday, such  action
        may be taken on the next succeeding day not a Saturday, Sunday or
        legal holiday.

             10.10     Foreign Nationals

             Without amending the Plan, Awards may be granted to  persons
        who are foreign nationals or  employed outside the United  States
        or both,  on  such  terms and  conditions  different  from  those
        specified in the Plan, as may,  in the judgment of the Board,  be
        necessary or desirable to further the purpose of the Plan.

        11.  Termination and Amendment

             The Plan  shall  remain  in  full  force  and  effect  until
        terminated by the Board.   Subject to the  last sentence of  this
        Section 11, the Board may at any time or times amend the Plan  or
        any outstanding Award  for any purpose  that may at  the time  be
PAGE
<PAGE>
                                       12

        permitted by law, or may at any time terminate the Plan as to any
        further grants of Awards. 


                                                           Exhibit 10.54

        Company's strategic goals and long-term growth and prosperity.

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

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

        SECTION 5.     Federal Income Tax Treatment of Loans.

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

        SECTION 6.     Maturity of Loans.

             Each Loan  to a  Key  Employee hereunder  shall be  due  and
        payable on demand  by the Company.   If no  such demand is  made,
        then each  Loan  shall mature  and  the principal  thereof  shall

                                        2PAGE
<PAGE>
        become due and payable in five equal annual installments from the
        payment of  annual cash  incentive compensation  (referred to  as
        bonus) to the  Key Employee  by the Company,  beginning with  the
        first such bonus  payment to  occur after  the date  of the  Note
        evidencing the Loan, and on each  of the next four bonus  payment
        dates.  Each Loan shall  also become immediately due and  payable
        in full,  without demand,  upon   the occurrence  of any  of  the
        events set forth in the Note; provided that the Committee may, in
        its sole and absolute discretion,  authorize an extension of  the
        time for repayment of  a Loan upon such  terms and conditions  as
        the Committee may determine.

        SECTION 7.     Amendment and Termination of the Plan.

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

        SECTION 8.     Miscellaneous Provisions.

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

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

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

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

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

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

        SECTION 9.     Effective Date.

        $_________                                                       
                                                Dated:____________


             For value  received, ________________,  an individual  whose
        residence is located at _______________________ (the "Employee"),
        hereby  promises  to  pay  to  Thermo  Ecotek  Corporation   (the
        "Company"), or assigns, ON DEMAND, but  in any case on or  before
        [insert date which is the fifth anniversary of date of  issuance]
        (the "Maturity  Date"),  the principal  sum  of [loan  amount  in
        words] ($_______), or such part  thereof as then remains  unpaid,
        without interest.  Principal shall be payable in lawful money  of
        the United States of America, in immediately available funds,  at
        the principal office of the Company or at such other place as the
        Company may  designate  from  time  to time  in  writing  to  the
        Employee. 

              Unless the Company has already made a demand for payment in
        full of this Note, the Employee  agrees to repay the Company   an
        amount equal to 20% of the  initial principal amount of the  Note
        from the payment of annual cash incentive compensation  (referred
        to as bonus) to the Employee  by the Company, beginning with  the
        first such bonus payment  to occur after the  date of this  Note,
        and on each  of the next  four bonus payment  dates.  Any  amount
        remaining unpaid under this Note, if  no demand has been made  by
        the Company, shall be due and payable on the Maturity Date.

             This Note may be prepaid at  any time or from time to  time,
        in whole  or  in part,  without  any  premium or  penalty.    The
        Employee acknowledges and agrees that the Company has advanced to
        the Employee the principal  amount of this  Note pursuant to  the
        Company's Stock Holding Assistance Plan,  and that all terms  and
        conditions of such Plan are incorporated herein by reference.  

             The unpaid principal amount of this Note shall be and become
        immediately due  and payable  without notice  or demand,  at  the
        option of  the  Company,  upon  the  occurrence  of  any  of  the
        following events:

                  (a)  the termination of the Employee's employment  with
             the Company, with or without cause, for any reason or for no
             reason;

                  (b)  the death or disability of the Employee;

                                        5PAGE
<PAGE>
                  (c)  the failure  of the  Employee to  pay his  or  her
             debts as they  become due, the  insolvency of the  Employee,
             the filing by or against the Employee of any petition  under
             the United  States Bankruptcy  Code (or  the filing  of  any
             similar  petition   under   the  insolvency   law   of   any
             jurisdiction),  or  the  making   by  the  Employee  of   an
             assignment or trust mortgage for the benefit of creditors or
             the appointment of  a receiver, custodian  or similar  agent
             with respect  to,  or  the  taking by  any  such  person  of
             possession of, any property of the Employee; or

                  (d)  the issuance of any writ of attachment, by trustee
             process or otherwise, or any restraining order or injunction
             not removed, repealed or  dismissed within thirty (30)  days
             of issuance, against or affecting the person or property  of
             the Employee or any liability or obligation of the  Employee
             to the Company.

             In case any payment  herein provided for  shall not be  paid
        when due,  the Employee  further  promises to  pay all  costs  of
        collection, including all reasonable attorneys' fees.

             No  delay  or  omission  on  the  part  of  the  Company  in
        exercising any right hereunder shall operate as a waiver of  such
        right or of any other right of the Company, nor shall any  delay,
        omission or waiver  on any  one occasion be  deemed a  bar to  or
        waiver of the  same or any  other right on  any future  occasion.
        The  Employee  hereby  waives  presentment,  demand,  notice   of
        prepayment,  protest  and  all  other  demands  and  notices   in
        connection with the delivery, acceptance, performance, default or
        enforcement of this Note.  The undersigned hereby assents to  any
        indulgence  and  any  extension  of  time  for  payment  of   any
        indebtedness  evidenced  hereby  granted  or  permitted  by   the
        Company.  

             This Note  has been  made pursuant  to the  Company's  Stock
        Holding Assistance Plan and shall be governed by and construed in
        accordance with, such Plan and the laws of the State of  Delaware
        and shall have the effect of a sealed instrument.

    Notes to Consolidated Financial Statements

    1.   Nature of Operations and Summary of Significant Accounting Policies

    Nature of Operations

         Thermo Ecotek Corporation (the Company) is an environmental company
    providing a range of environmentally responsible technologies and
    products, including non-utility electric power generation using clean
    combustion processes, engineered clean fuels, as well as environmentally
    friendly pest control products through its biopesticides subsidiary,
    Thermo Trilogy Corporation (Thermo Trilogy) (Note 4).

         The Company is principally engaged in the development and operation
    of alternative-energy electrical generation facilities. The Company
    develops and operates facilities through joint ventures or limited
    partnerships in which the Company has a majority interest, or through
    wholly owned subsidiaries (the Operating Companies). The Company's
    interests in the Operating Companies range from 60% to 100% and, in each
    case, are held by wholly owned subsidiaries of the Company. Of the
    facilities operated by the Company, three are owned by the Company and
    the remainder are owned by unaffiliated parties who lease them to the
    Operating Companies under long-term leases (Note 9).

    Relationship with Thermo Electron Corporation

         The Company was incorporated on November 30, 1989 as a wholly owned
    subsidiary of Thermo Electron Corporation (Thermo Electron). At September
    28, 1996, Thermo Electron owned 20,064,619 shares (adjusted to reflect
    the three-for-two stock split distributed in October 1996 in the form of
    a 50% stock dividend) of the common stock of the Company, representing
    83% of the outstanding shares.

    Principles of Consolidation

         The accompanying financial statements include the accounts of the
    Company and its majority-owned and wholly owned Operating Companies. All
    significant intercompany accounts and transactions have been eliminated
    in consolidation. The Company accounts for investments in businesses in
    which it owns between 20% and 50% using the equity method.

    Fiscal Year

         In June 1995, the Company changed its fiscal year end from the
    Saturday nearest December 31 to the Saturday nearest September 30.
    Accordingly, the Company's transition period, which ended on September
    30, 1995, was the 39-week period from January 1, 1995 to September 30,
    1995, referenced as "fiscal 1995." References to "fiscal 1996" and "1994"
    are for the years ended September 28, 1996 and December 31, 1994,
    respectively. Fiscal 1996 and 1994 each included 52 weeks. The unaudited
    consolidated statements of income and cash flows for the 52-week period
    ended September 30, 1995 are presented for comparative purposes only.

    Cash Equivalents and Restricted Funds

         As of September 28, 1996, $53,250,000 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 corporate notes, U.S. government agency
    securities, money market funds, commercial paper, 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 also
    include investments in money market accounts. The use of cash and cash
    equivalents totaling $7,603,000 and $6,402,000 at September 28, 1996 and
    September 30, 1995, respectively, was restricted by the terms of certain
    Operating Companies' lease and financing agreements.

         Restricted funds in the accompanying balance sheet represent
    amounts held in trust for lease and debt payments and working capital
    requirements, as required by certain of the Operating Companies' lease
    and financing agreements, and are invested in money market accounts.
    Restricted funds that are not expected to be used within the next fiscal
    year are classified as long-term in the accompanying balance sheet.

         All cash equivalents and restricted funds are carried at cost,
    which approximates market value.

    Inventories

         Inventories consist of raw materials, fuel, operating supplies,
    spare parts, and include, where applicable, materials and overhead.
    Inventories are stated at the lower of cost (on a first-in, first-out or
    average basis) or market value. Work in process and finished goods were
    not material at fiscal year-end 1996 and 1995.

    Available-for-sale Investments

         Pursuant to Statement of Financial Accounting Standards (SFAS)
    No. 115, "Accounting for Certain Investments in Debt and Equity
    Securities," the Company's investments in long-term debt and marketable
    equity securities are accounted for at market value (Note 3).

    Other Assets

         Other assets in the accompanying balance sheet include certain
    costs associated with the development, pre-operation, and startup of the
    Company's alternative-energy facilities; prepaid rent relating to an
    Operating Company's lease agreement; and goodwill that arose in
    connection with the acquisition of an Operating Company. In fiscal 1996,
    other assets also include deferred debt expense relating to the Company's
    March 1996 issuance of subordinated convertible debentures (Note 13), and
    patents, licenses, and other intangible assets arising from the Thermo
    Trilogy acquisition (Note 4). These assets are being amortized using the
    straight-line method over their estimated useful lives, which range from
    5 to 30 years. These assets were $12.2 million and $9.2 million, net of
    accumulated amortization of $4.5 million and $3.7 million, at fiscal
    year-end 1996 and 1995, respectively.

         In addition, other assets include an investment in a joint venture
    in fiscal 1996 and an investment in KFx, Inc. (Note 3) in fiscal 1995.

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

    Other Deferred Items

         Other deferred items in the accompanying balance sheet include rent
    that has been recognized ratably for financial reporting purposes in
    connection with an Operating Company's lease agreement (Note 9) and
    deferred income in connection with the termination of a power-sale
    agreement (Note 12).

    Revenue Recognition

         The Company earns revenues primarily from the operation of
    alternative-energy facilities. Revenues from plant operations are
    recorded as electricity is delivered. The Operating Companies have
    long-term power supply arrangements with local utilities, expiring
    between 2005 and 2020, to sell all the output of the plants currently in
    operation at established or formula-based defined rates (Note 11). Under
    certain of these arrangements, in the event of service termination by the
    Operating Companies prior to the end of the obligation period, the
    Operating Companies may be required to reimburse the utilities to the
    extent that cumulative revenue calculated at established rates exceeds
    the amounts calculated at the utilities' "avoided cost" rates. Management
    does not expect to incur any obligation under these provisions in the
    foreseeable future.

         The Woodland plant has conditions in its nonrecourse lease
    agreement that require the funding of a "power reserve" in years prior to
    2000, based on projections of operating cash flow shortfalls in 2000 and
    thereafter. The power reserve represents funds available to make lease
    payments in the event that revenues are not sufficient after the plant
    converts to avoided-cost rates in March 2000. This funding requirement
    will significantly limit future profit distributions that Woodland may
    make to the Company. Accordingly, beginning in the first quarter of
    fiscal 1997, the Company will record as an expense, the funding of
    reserves required under Woodland's nonrecourse lease agreement to cover
    projected shortfalls in lease payments beginning in 2000. Consequently,
    the Company expects that the results of the Woodland plant will be
    reduced to approximately breakeven beginning in fiscal 1997 and
    thereafter. During fiscal 1996, the Woodland plant contributed $5.1
    million of operating income.

    Repairs and Maintenance

         The Company charges routine repairs and maintenance to expense in
    the period the costs are incurred. The Company accrues for major
    maintenance and overhauls in anticipation of scheduled outages. Other
    accrued expenses in the accompanying balance sheet includes approximately
    $4.7 million and $2.5 million at fiscal year-end 1996 and 1995,
    respectively, in anticipation of major maintenance and overhauls.

    Income Taxes

         The Company and Thermo Electron have a tax allocation agreement
    under which the Company is included in the consolidated federal and
    certain state income tax returns filed by Thermo Electron. The agreement
    provides that Thermo Electron charges or pays the Company amounts based
    on the Company's relative contribution to Thermo Electron's tax
    liability. If Thermo Electron's equity ownership of the Company were to
    drop below 80%, the Company would be required to file its own tax
    returns.

         In accordance with 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

         Primary earnings per share have been computed based on the weighted
    average number of common shares outstanding and common stock equivalents
    where dilutive, except for the effect of options granted during 1994
    which, in accordance with Securities and Exchange Commission rules, was
    reflected in earnings per share for 1994. Common stock equivalents in all
    periods represent the effect of the assumed exercise of stock options,
    where material. In addition, in fiscal 1996, common stock equivalents
    include the assumed conversion of the noninterest-bearing subordinated
    convertible debentures. Fully diluted earnings per share assumes the
    exercise of stock options and the assumed conversion of the Company's
    subordinated convertible debentures, and elimination of the related
    interest expense.

    Stock Split

         In September 1996, the Company declared a three-for-two stock split
    in the form of a 50% stock dividend, payable on October 16, 1996, to
    shareholders of record as of October 2, 1996. All share and per share
    information, except for share information in the accompanying balance
    sheet, has been restated to reflect the stock split.

    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.

    3.   Available-for-sale Investments

         The Company accounts for certain investments in accordance with
    SFAS No. 115, "Accounting for Certain Investments in Debt and Equity
    Securities." In accordance with SFAS No. 115, the Company's marketable
    equity securities are considered available-for-sale investments in the
    accompanying balance sheet and are carried at market value, with the
    difference between cost and market value, net of related tax effects,
    recorded currently as a component of shareholders' investment titled "Net
    unrealized gain on available-for-sale investments." As of September 28,
    1996, the Company held one long-term available-for-sale investment, an
    investment in the common stock of KFx, Inc. (KFx), described below. 

         In August 1995, the Company purchased 1,500,000 shares of KFx
    common stock representing an approximate 7% equity interest in KFx. The
    cost of the purchase was $3,000,000. In fiscal 1996, the Company
    purchased an additional 1,500,000 shares of KFx common stock for
    $3,000,000, bringing its total equity interest in KFx to approximately
    14%. This investment was not accounted for as an available-for-sale
    investment in fiscal 1995 due to certain restrictions on the resale of
    the stock, which expire on January 1, 1997. The fair market value of this
    investment at September 28, 1996 was $20,254,000. Pursuant to the
    purchase agreement, the Company has the right, but not the obligation, to
    purchase an additional 1,250,000 shares of KFx common stock for $2.00 per
    share at any time from December 1, 1996 through January 31, 1997, if such
    shares are made available by KFx. Simultaneously with the execution of
    the purchase agreement, KFx granted to the Company a warrant to purchase
    an additional 7,750,000 shares at $3.65 per share, as well as a warrant
    to purchase further shares of the common stock of KFx at market value,
    defined so that the number, when added to all other shares of such common
    stock owned by the Company, would result in the Company owning 51% of the
    common stock of KFx on a fully-diluted basis. These warrants are
    exercisable from January 1, 2000 through July 1, 2001, but would
    terminate in the event that the Company did not purchase the shares made
    available by KFx as described above.


    4.   Acquisition and Projects Under Development

    Acquisition

         In May 1996, the Company, through two wholly owned subsidiaries,  
    acquired the net assets of the biopesticides division of W.R. Grace & Co.
    (renamed Thermo Trilogy) which develops, manufactures, and markets
    environmentally friendly products used for pest control, for $8.1 million
    in cash. In addition, the Company will pay a royalty fee of seven percent
    on annual sales of the acquired business in excess of $14 million through
    the year 2000.

         This acquisition has been accounted for using the purchase method
    of accounting and its results of operations have been included in the
    accompanying financial statements from the date of acquisition. The
    aggregate cost of this acquisition approximated the fair value of the net
                                       16PAGE

    assets acquired and is subject to adjustment upon finalization of the
    purchase price allocation. Pro forma data is not presented since this
    acquisition was not material to the Company's results of operations and
    financial position.

    Projects Under Development

         In August 1995, the Company, through two wholly owned subsidiaries,
    entered into a Limited Partnership Agreement with KFx Wyoming, Inc., a
    subsidiary of KFx, to develop, construct, and operate a 500,000-ton-per-
    year subbituminous coal-beneficiation plant near Gillette, Wyoming. The
    Company is committed to provide approximately $48 million for the design,
    construction, and operation of the plant and will have a 95% equity
    interest in the project. Construction began in August 1995 with
    commercial operations expected to begin in the first half of fiscal 1997.
    As of September 28, 1996, the Company is committed to fund an additional
    $9.3 million to complete construction of the facility. The Company has
    also made an investment in KFx (Note 3).

         In July 1995, the Company entered into an agreement to invest $15
    million in a 185-megawatt combined cycle, steam-turbine electric
    generation facility located in Puerto Plata, Dominican Republic, owned by
    Smith/Enron Cogeneration Limited Partnership (SECLP). Under the terms of
    the agreement, the Company will acquire both a general and limited
    partnership interest in Smith Cogeneration Dominicana L.P. (Smith
    Cogeneration), which through its investment in SECLP, owns approximately
    50% of the project. The Company will receive a minority interest in Smith
    Cogeneration equivalent to a specified percentage of all project cash
    flow and profits and losses. The Company's exact percentage interest in
    Smith Cogeneration will not be finally determined until six months after
    the funding of the Company's investment, which is expected to occur
    during calendar 1997, assuming certain conditions are met.


    5.   Shareholders' Investment 

         In June 1996, the Company sold 330,000 shares of its common stock
    in a private placement at $16.08 per share, for net proceeds of $5.0
    million.

         In February 1995, the Company sold 3,500,334 shares of its common
    stock in an initial public offering at $8.50 per share, for net proceeds
    of approximately $27.5 million.

         Substantially all of the net assets of the Company represent net
    assets of the Operating Companies. The net assets of certain Operating
    Companies are generally restricted as to the amounts that can be
    transferred to the parent company in the form of dividends, loans or
    advances, pursuant to certain lease or debt agreements. As of September
    28, 1996, net assets of certain subsidiaries of approximately $73.3
    million were not restricted from distribution.

    Notes to Consolidated Financial Statements

    5.   Shareholders' Investment (continued)

         At September 28, 1996, the Company had reserved 12,731,796 unissued
    shares of its common stock for possible issuance under stock-based
    compensation plans and for issuance upon possible conversion of the
    Company's convertible obligations.


    6.   Stock-based Compensation Plans

         The Company has stock-based compensation plans for its key
    employees, directors, and others. Two of these plans, adopted in 1990,
    permit the grant of nonqualified and incentive stock options. A third
    plan, adopted in 1994, 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 the
    Company's plans. The option recipients and terms of options granted under
    these plans are determined by the Board Committee. Options granted under
    these plans are exercisable immediately and expire seven to twelve years
    after the date of grant. However, the shares acquired upon exercise are
    subject to certain transfer restrictions and repurchase by the Company at
    the exercise price, upon certain events. These restrictions and
    repurchase rights generally lapse ratably over periods ranging from five
    to ten years after the first anniversary of the grant date, depending on
    the term of the option, which may range from seven to twelve years.
    Nonqualified 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, adopted in 1991, that provides
    for the grant of stock options to outside directors pursuant to a formula
    approved by the Company's shareholders. Options awarded under this plan
    are exercisable six months after the date of grant and expire three to
    seven years after the date of grant. In addition to the Company's stock
    option plan, certain officers and key employees may also participate in
    stock-based compensation plans of Thermo Electron or its majority-owned
    subsidiaries.

  7.   Employee Benefit Plans

  401(k) Savings Plan and Employee Stock Ownership Plan

       Substantially all of the Company's corporate, full-time employees are
  eligible to participate in Thermo Electron's 401(k) savings plan and employee
  stock ownership plan (ESOP). Contributions to the Thermo Electron 401(k)
  savings plan are made by both the employee and the Company. Company
  contributions are based upon the level of employee contributions. The Company
  contributed and charged to expense for these plans $114,000, $66,000, and
  $138,000 in fiscal 1996, fiscal 1995, and 1994, 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, ESOP II plan was terminated and as a result, the Company's
  employees are no longer eligible to participate in an ESOP.

    Notes to Consolidated Financial Statements

    7.   Employee Benefit Plans (continued)

         Employees of the Operating Companies who meet eligibility
    requirements may participate in a separate defined contribution plan.
    Contributions to the plan are made by both the employee and the Operating
    Companies. The Operating Companies' contributions are based on the level
    of employee contributions. The Company contributed and charged to expense
    for these plans $165,000, $91,000, and $131,000 in fiscal 1996, fiscal
    1995, and 1994, respectively.

    Employee Stock Purchase Plan

          Prior to November 1, 1996, the Company's eligible corporate
    employees could participate in an employee stock purchase plan sponsored
    by Thermo Electron, under which employees could purchase shares of Thermo
    Electron common stock. Effective November 1, 1996, substantially all of
    the Company's employees may participate in employee stock purchase plans
    sponsored by the Company and Thermo Electron, under which employees can
    purchase shares of the Company's and Thermo Electron's common stock.
    Under these plans, shares of common stock may be purchased at the end of
    a 12-month plan year at 95% of the fair market value at the beginning of
    the plan year, and shares purchased are subject to a six-month resale
    restriction. Prior to November 1, 1995, shares of Thermo Electron's
    common stock could be purchased at 85% of the fair market value at the
    beginning of the plan year, and 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.


    8.    Income Taxes

          The components of the provision for income taxes for fiscal 1996,
    fiscal 1995, and 1994 are as follows:

    8.    Income Taxes (continued)

          The provision for income taxes in the accompanying statement of
    income for fiscal 1996, fiscal 1995, and 1994 differs from the amounts
    computed by applying the statutory federal income tax rate of 34% to
    income before provision for income taxes and minority interest, due to
    the following:

          Tax losses and credits benefited during fiscal 1996 relate to the
    resolution of certain tax contingencies.

          Prepaid income taxes and deferred income taxes as of fiscal year-
    end 1996 and 1995 consist of the following:

          The valuation allowance relates to uncertainty surrounding the
    realization of certain state tax loss carryforwards and stock option
    exercises not benefited. The increase in the valuation allowance in
    fiscal 1996 relates to an increase in state tax losses not benefited and
    other state tax assets. State tax loss carryforwards of approximately $20
    million will begin to expire in 1997. Of the fiscal 1996 valuation
    allowance, $898,000 will be used to increase capital in excess of par
    value when previously unrealized stock option benefits are recognized.
    The long-term due from parent company in the accompanying balance sheet
    represents amounts due from Thermo Electron for tax benefits arising from
    the Company's operations.

    9.    Commitments

    Leases

          The Company has leased its office facilities from Thermo Electron.
    The agreement called for the Company to pay rent based on Thermo
    Electron's occupancy costs per square foot. The accompanying statement of
    income includes expenses of $177,000, $143,000, and $176,000 in fiscal
    1996, fiscal 1995, and 1994, respectively. The Company plans to move its
    office facilities in fiscal 1997 and has signed a seven-year fixed rate
    lease agreement with a third party that expires in 2003. The Company's
    commitment under this new lease agreement will be approximately $300,000
    per fiscal year, net of sublease income of $178,000 per fiscal year.

          Certain Operating Companies have operating lease agreements for
    their facilities expiring in various years through 2010. The lease
    agreements provide for renewal of each of the leases for additional
    periods ranging from one to five years at the Operating Companies'
    option. In general, renewal options are at the lower of a predetermined
    percentage of the average annual lease rental during the lease terms or
    the fair market rental as determined by an independent appraisal. In
    general, at the end of the lease terms or renewal terms, the Operating
    Companies have a right of first refusal or an option to purchase the
    facilities, at their fair market value, as determined by an independent
    appraisal. During fiscal 1995, the Company amended an existing facility
    operating lease, which resulted in the agreement being treated as a
    capital lease (Note 13).

          Lease payments under the operating leases are made to the owner of
    the facility only to the extent that power revenues exceed essential
    operating expenses, as defined, up to certain specified maximum levels
    (Note 10). Subject to the foregoing, as of September 28, 1996, the
    contractual amounts payable pursuant to the lease agreements total
    approximately $164,253,000 over the remaining initial lease terms,
    averaging approximately $16,000,000 per year. The Company recognizes rent
    expense ratably over the respective lease terms. The accompanying
    statement of income includes expenses from operating leases (excluding
    the operating lease with Thermo Electron) of $15,233,000, $13,402,000,
    and $23,385,000 in fiscal 1996, fiscal 1995, and 1994, respectively.

    Fuel Supply

          The Operating Companies have entered into fuel supply agreements
    with various suppliers guaranteeing the purchase of certain minimum
    quantities of acceptable fuel at negotiated prices and terms. The
    Operating Companies purchased $20,013,000, $13,804,000, and $22,615,000
    of fuel under such contracts in fiscal 1996, fiscal 1995, and 1994,
    respectively. The agreements call for price adjustments based on certain
    published indices or stated rates over their terms expiring between 1997
    and 2005. See Note 10 for fuel supply agreements with related parties.

    10.   Related Party Transactions

    Corporate Service 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
    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
    by mutual agreement of the parties. For these services, the Company was
    charged $1,570,000, $1,286,000, and $1,678,000 in fiscal 1996, fiscal
    1995, and 1994, respectively. 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. 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). 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.

    Fuel Supply

          A portion of the fuel used by the Operating Companies' facilities
    is obtained under agreements with related parties of the Operating
    Companies or their joint venture partners (Note 9). During fiscal 1996,
    fiscal 1995, and 1994, the Company paid $4,563,000, $2,946,000, and
    $4,331,000, respectively, under these agreements.

    Management Fees

          One of the Operating Companies has entered into management
    agreements with a related party of its joint venture partner for the
    day-to-day operation of its facility and the procurement and management
    of fuel. During fiscal 1996, fiscal 1995, and 1994, the Company paid
    $350,000, $253,000, and $322,000, respectively, under these agreements.

    Thermo Electron Guarantees

          Thermo Electron has issued an operating standards support
    agreement for each of the facilities leased or financed by the Operating
    Companies. These agreements provide that Thermo Electron will loan the
    Operating Companies, on a subordinated basis, enough funds to meet their
    lease or debt payments in the event the power plants are unable to
    generate power at a designated level and such inability is related to the
    design, construction, operation or maintenance of the plants and not
    caused by certain uncontrollable circumstances.

<PAGE>
    Thermo Ecotek Corporation
    Notes to Consolidated Financial Statements

    10.   Related Party Transactions (continued)

          Thermo Electron has also guaranteed the lease payments of one of
    the Operating Companies under certain events. Under the terms of this
    guarantee, Thermo Electron will loan funds to the Operating Company to
    cover any shortfall in its lease payment in the event and to the extent
    the terms of the Operating Company's power purchase agreements are
    changed by Public Service Company of New Hampshire (PSNH) (Note 11). No
    such payments have been required under this guarantee.

          The Company and Thermo Electron have entered into a Master
    Reimbursement Agreement through which the Company will reimburse Thermo
    Electron in the event that Thermo Electron is required to make any
    payments pursuant to guarantees, including those guarantees described
    above.

    Operating Lease

          See Note 9 for a description of the Company's operating lease with
    Thermo Electron.

    Long-term Obligations

          See Note 13 for long-term obligations of the Company held by
    Thermo Electron.

    Repurchase Agreement

          The Company invests excess cash in a repurchase agreement with
    Thermo Electron as discussed in Note 1.


    11.   Contingencies

         Two of the Operating Companies have Rate Orders from the New
    Hampshire Public Utilities Commission (NHPUC) to sell all of their power
    to PSNH. An agreement between Northeast Utilities, parent to PSNH, and
    the State of New Hampshire, arising from the settlement of PSNH
    bankruptcy proceedings, contains language to the effect that PSNH will
    seek to renegotiate some of the terms of certain rate orders with small
    power producers and that the state will support PSNH in such efforts.
    PSNH has commenced discussions with these two Operating Companies and
    other small power producers through which it is seeking to renegotiate
    the rate orders applicable to the Company's and other facilities. The
    state, acting through NHPUC, has indicated that it supports such efforts.

         Based on negotiations between the Operating Companies and PSNH, the
    Company believes that this matter may reach resolution in fiscal 1997,
    although final resolution is subject to approval of the NHPUC. Should the
    matter not reach resolution, the Company does not believe that PSNH has
    the right to take unilateral action to reduce the price of purchased
    power under such arrangements. Rejection of the Company's rate orders
    would result in a claim for damages by the Company and could be the
    subject of lengthy litigation. Although unfavorable resolution of this
    matter could materially affect the Company's results of operations and
                                       24PAGE
<PAGE>
    Thermo Ecotek Corporation
    Notes to Consolidated Financial Statements

    11.  Contingencies (continued)

    cash flows, the Company believes that any resolution will not have a
    material adverse impact on the Company's financial position. 

         The Company is contingently liable with respect to lawsuits and
    matters that arose in the normal course of business. In the opinion of
    management, these contingencies will not have a material adverse effect
    on the financial position or results of operations of the Company.


    12.  Termination of Power-Sales Agreement

         On August 2, 1993, in exchange for a cash settlement, the Company
    agreed to terminate a power-sales agreement with a utility, which
    required the utility to purchase the power that was to be generated by
    the Company's 55-megawatt natural gas cogeneration facility under
    development in Staten Island, New York.

         Under the agreement, the Company has received $17.1 million through
    fiscal 1996, with a future payment due of $900,000 on May 1, 1997, plus
    interest at 5.8%. The payment due in May 1997 is included in other
    current assets and note receivable in the accompanying balance sheet as
    of September 28, 1996 and September 30, 1995, respectively.

         The Company would be obligated to return $8.2 million of this
    settlement if the Company elects to proceed with the Staten Island
    facility and the plant commences commercial operation before January 1,
    2000. Accordingly, the Company has deferred recognition of $8.2 million
    of revenues, pending final determination of the project's status. The
    deferred revenue is included in other deferred items in the accompanying
    balance sheet.

    fiscal 1996, $5.3 million principal amount of the debentures was
    converted into 388,862 shares of the Company's common stock.

    13.   Long-term Obligations (continued)

          The tax-exempt revenue bonds were issued by the California
    Pollution Control Financing Authority to finance the construction of the
    Delano I and Delano II facilities. The obligations are credit-enhanced by
    a letter of credit issued by a bank group. Repayment of the debt is an
    obligation of Delano and the obligations are nonrecourse to the Company.
    As of September 28, 1996, Delano I and Delano II plant and equipment
    totaling approximately $173.0 million were collateral for this debt.

          On June 30, 1995, the Mendota Operating Company entered into a
    First Amendment to its Project Lease. The Amendment, effective April 1,
    1995, modified, among other terms of the lease, the lease term, the base
    rent, the application of cash flow from the facility, and the lessee's
    option to purchase the facility. The terms of the lease, as amended, met
    the requirements for treatment as a capital lease and accordingly, the
    facility has been recorded as an asset of the Company in the amount of
    $47.0 million and is included in property, plant and equipment, net in
    the accompanying balance sheet.

          The future minimum lease payments under the amended lease are as
    follows:

    Notes to Consolidated Financial Statements

    14.   Significant Customers and Concentrations of Credit Risk

          Revenues from three electric utility customers as a percentage of
    total revenues were approximately 21%, 36%, and 36% in fiscal 1996; 22%,
    36%, and 36% in fiscal 1995; and 20%, 40%, and 33% in 1994.

          At fiscal year-end 1996 and 1995, substantially all accounts
    receivable due to the Company were from its four electric utility
    customers. The Company does not normally require collateral or other
    security to support its accounts receivable. Management does not believe
    that this concentration of credit risk has or will have a significant
    negative impact on the Company.

    15.   Fair Value of Financial Instruments

          The Company's financial instruments consist mainly of cash and
    cash equivalents, restricted funds, accounts and note receivable,
    long-term available-for-sale investments, due from parent company,
    current portion of long-term obligations, accounts payable, due to parent
    company, long-term obligations, and interest rate swaps. The carrying
    amounts of these financial instruments, with the exception of long-term
    available-for sale investments, due from parent company, long-term
    obligations, and interest rate swaps, approximate fair value due to their
    short-term nature.

          The Company's long-term available-for-sale investments are carried
    at fair value in the accompanying balance sheet. The fair value was
    determined based on a quoted market price. See Note 3 for the fair value
    information pertaining to this financial instrument. The carrying amount
    of due from parent company in the accompanying balance sheet approximates
    fair value.

          The fair value of long-term obligations was determined based on
    quoted market prices and on borrowing rates available to the Company at
    the respective year ends. The fair value of convertible obligations at
    fiscal year-end 1996 and 1995 exceeds the carrying amount primarily due
    to the market price of the Company's common stock exceeding the
    conversion price of the convertible obligations. The carrying amount and
    fair value of the Company's long-term obligations and off-balance sheet
    financial instruments at fiscal year-end 1996 and 1995 are as follows:

                                             1996                1995

    15.   Fair Value of Financial Instruments (continued)

         Interest rate swap agreements are in place on the borrowings
    associated with the Delano I and Delano II facilities and are with a
    different counterparty than the holders of the underlying debt. These
    swaps have terms expiring in December 2000 commensurate with the final
    maturity of the debt. The swaps have effectively converted floating rate
    debt to fixed rate borrowings. Interest expense is adjusted with changes
    in the interest rate and management believes any credit risk is remote.
    The notional amount of the swap agreements was $95.7 million and $110.0
    million at fiscal year-end 1996 and 1995, respectively. The fair value of
    such agreements is the estimated amount that the Company would pay upon
    termination of the contract, taking into account the change in market
    interest rates and creditworthiness of the counterparties. During fiscal
    1996 and fiscal 1995, the average variable rate received under the swap
    agreement was 3.6% and 3.8%, respectively.

    Report of Independent Public Accountants


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

         We have audited the accompanying consolidated balance sheet of
    Thermo Ecotek Corporation (a Delaware corporation and majority-owned
    subsidiary of Thermo Electron Corporation) and subsidiaries as of
    September 28, 1996 and September 30, 1995 and the related consolidated
    statements of income, shareholders' investment, and cash flows for the
    year ended September 28, 1996, the nine months ended September 30, 1995,
    and the year ended December 31, 1994. These financial statements are the
    responsibility of the Company's management. Our responsibility is to
    express an opinion on these consolidated financial statements based on
    our audits.

         We conducted our audits in accordance with generally accepted
    auditing standards. Those standards require that we plan and perform the
    audit to obtain reasonable assurance about whether the financial
    statements are free of material misstatement. An audit includes
    examining, on a test basis, evidence supporting the amounts and
    disclosures in the financial statements. An audit also includes assessing
    the accounting principles used and significant estimates made by
    management, as well as evaluating the overall financial statement
    presentation. We believe that our audits provide a reasonable basis for
    our opinion.

         In our opinion, the consolidated financial statements referred to
    above present fairly, in all material respects, the financial position of
    Thermo Ecotek Corporation and subsidiaries as of September 28, 1996 and
    September 30, 1995 and the results of their operations and their cash
    flows for the year ended September 28, 1996, the nine months ended
    September 30, 1995, and the year ended December 31, 1994, in conformity
    with generally accepted accounting principles.

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

         Forward-looking statements, within the meaning of Section 21E of
    the Securities Exchange Act of 1934, are made throughout this
    Management's Discussion and Analysis of Financial Condition and Results
    of Operations. These statements involve a number of risks and
    uncertainties, including those detailed immediately after this
    Management's Discussion and Analysis of Financial Condition and Results
    of Operations under the caption "Forward-looking Statements."

    Overview

         The Company earns revenues primarily from the operation of
    independent electric power generation facilities through joint ventures,
    limited partnerships, or wholly owned subsidiaries (the Operating
    Companies). Each Operating Company sells power under a long-term power-
    sale agreement. The profitability of operating the Company's facilities
    depends on the price received for power under the power-sale agreements
    with power purchasers, on plant performance or availability, on the
    degree to which utilities exercise curtailment rights granted under
    power-sale agreements, and on the fuel, operating, and maintenance costs
    for the facilities. Curtailment rights allow a utility to require an
    Operating Company to curtail power output up to pre-established annual
    levels during periods of low system demand. A utility commonly
    experiences low system demand during periods when hydroelectric power is
    available, generally following periods of heavy rain or snow. The
    contractually allowable maximum for such curtailment at both the Woodland
    and Mendota plants is 1,000 hours per year. The Company experienced
    approximately 930 and 950 hours of curtailment at each of the two plants
    during fiscal 1996 and fiscal 1995, respectively. In 1994, the Company
    experienced no curtailment at these two plants. The Company earns a
    disproportionately high share of its income from May to October due to
    the rate structures under the power-sale agreements for its California
    plants, which provide strong incentives to operate during this period of
    high demand. Conversely, the Company has historically operated at a loss
    or marginal profitability during its second fiscal quarter due to the
    rate structure under these agreements. The Company's profitability is
    also dependent on the amount of development expenses that it incurs.

         The Company is expanding beyond biomass power generation into other
    environmentally responsible products and processes. Through two wholly
    owned subsidiaries, the Company acquired the biopesticides division of
    W.R. Grace & Co. (renamed Thermo Trilogy), which develops, manufactures,
    and markets environmentally friendly products used for pest control.
    Derived from seeds of the tropical "neem" tree and specially developed
    microbials, these biopesticides safely and effectively control insects,
    fungi, and mites on numerous crops. The Company has also entered the
    field of engineered "clean" fuels through a partnership agreement with
    KFx, Inc. (KFx). The Company is committed to provide approximately $48
    million for the design, construction, and operation of the first
    full-scale coal production facility to use a patented "clean coal"
    technology (K-Fuel technology). Once completed, the Gillette, Wyoming,
    facility will use the K-Fuel technology to transform high-moisture,
    low-energy coal into a low-moisture, high-energy, solid fuel.

    Overview (continued)

         The Company plans to expand its operations into international
    markets and has begun business development efforts in India, Italy, and
    the Czech Republic. The cost of business development efforts is expected
    to increase as the Company expands into these markets due to increased
    complexity inherent in foreign development. In addition, the amount of
    cash required to fund equity investments is expected to increase, due to
    the financing requirements of lenders in foreign markets.

    Results of Operations

         In June 1995, the Company changed its fiscal year end from the
    Saturday nearest December 31 of each year to the Saturday nearest
    September 30 of each year. Accordingly, the results of operations for
    1996 compares the year ended September 28, 1996 (fiscal 1996) with the
    unaudited year ended September 30, 1995 (1995). The results of operations
    for 1995 compares the nine months ended September 30, 1995 (fiscal 1995)
    with the unaudited nine months ended October 1, 1994 (fiscal 1994).

    Fiscal 1996 Compared With 1995

         Revenues in fiscal 1996 were $150.1 million, compared with $139.3
    million in 1995, an increase of $10.8 million. The increase was primarily
    due to higher contractual energy rates in fiscal 1996 at all of the
    Company's facilities, except the Hemphill plant, as well as fewer days of
    scheduled and unscheduled outages at the Delano plants, and the inclusion
    of $1.7 million in revenues from Thermo Trilogy, which was acquired in
    May 1996. Pursuant to the Company's utility contracts for its four plants
    in California, there will be no further contractual energy rate increases
    beginning in calendar 1998.

         The gross profit margin increased to 32% during fiscal 1996 from
    29% in 1995. The improvement results largely from the effect of higher
    energy rates in 1996 and, to a lesser extent, lower fuel costs.

         The Company's plants have power-sales agreements under which
    utilities presently purchase power at fixed rates. Certain of these
    arrangements contain provisions under which the utilities will convert
    from fixed rates to "avoided-cost" rates at specified dates. Avoided-cost
    rates are currently substantially less than the Operating Companies'
    fixed rates. The Woodland plant, which converts to avoided-cost rates in
    March 2000, has conditions in its nonrecourse lease agreement that
    require the funding of a "power reserve" in years prior to 2000, based on
    projections of operating cash flow shortfalls in 2000 and thereafter. The
    power reserve represents funds available to make lease payments in the
    event that revenues are not sufficient after the plant converts to
    avoided-cost rates.

    Thermo Ecotek Corporation


    Fiscal 1996 Compared With 1995 (continued)

         Although it is difficult to predict future levels of avoided costs,
    based on current estimates, avoided costs are expected to be lower in
    2000 than the rates currently being paid. If the Woodland plant were to
    operate at projected avoided-cost levels, substantial losses would
    result, primarily due to nonrecourse lease obligations that extend beyond
    2000. Absent sufficient reductions in fuel prices and other operating
    costs, under such circumstances the Company would either renegotiate its
    nonrecourse lease for the Woodland plant or forfeit its interest in the
    plant. Beginning in the first quarter of fiscal 1997, the Company will
    record as an expense the funding of reserves required under Woodland's
    nonrecourse lease agreement to cover projected shortfalls in lease
    payments beginning in 2000. As a result, the Company expects that the
    results of the Woodland plant will be reduced to approximately breakeven
    beginning in fiscal 1997 and thereafter. During fiscal 1996, the Woodland
    plant contributed $5.1 million of operating income.

         Public Service Company of New Hampshire (PSNH) is seeking to
    renegotiate the rate orders applicable to the Company's two New Hampshire
    facilities. The Company is currently negotiating with PSNH and believes
    that this matter may reach resolution in fiscal 1997, although final
    resolution is subject to approval of the New Hampshire Public Utilities
    Commission. Should resolution not occur, the Company does not believe
    that PSNH has the right to take unilateral action to reduce the price of
    purchased power under the rate orders. An unfavorable resolution of this
    matter could materially affect the Company's results of operations and
    cash flows, although the Company believes that any resolution will not
    have a material adverse impact on the Company's financial position.

         General and administrative expenses as a percentage of revenues
    were 8% in fiscal 1996, compared with 7% in 1995. The change results
    primarily from an ongoing increase in business development efforts and
    the inclusion of higher general and administrative expenses as a
    percentage of revenues at Thermo Trilogy.

         Interest income increased to $5.1 million in fiscal 1996 from $3.3
    million in 1995, primarily due to interest income earned on invested
    proceeds from the issuance of subordinated convertible debentures in
    March 1996 (Note 13) and the Company's initial public offering in
    February 1995. Interest expense increased to $14.7 million during fiscal
    1996 from $13.3 million in 1995, primarily due to the conversion of the
    Mendota plant lease to a capital lease effective April 1995.

         The effective tax rates were 28% and 34% in fiscal 1996 and 1995,
    respectively. The rates in both years reflect the exclusion of income
    taxed directly to minority partners, as well as the benefit of tax
    credits and loss carryforwards, offset in part by state income taxes. The
    decrease in the effective tax rate in fiscal 1996 is due to the
    recognition of tax loss and credit carryforwards as a result of the
    resolution of certain tax contingencies. The Company expects the
    effective tax rate in fiscal 1997 to decline due to tax credits resulting
    from production at the Company's coal-beneficiation facility.

    Fiscal 1996 Compared With 1995 (continued)

         Minority interest expense in fiscal 1996 and 1995, represents the
    allocation of income from plant operations to a minority partner in an
    Operating Company.

    Fiscal 1995 Compared With Fiscal 1994

         Revenues in fiscal 1995 increased 5% to $107.1 million from $102.1
    million in fiscal 1994. The increase was primarily due to the Whitefield,
    New Hampshire plant operating for the full 1995 period. During fiscal
    1994, this plant did not operate for most of the first six months due to
    major damage to the turbine-generator. The plant returned to normal
    operations late in the second quarter of fiscal 1994. In addition, higher
    contractual energy rates in fiscal 1995 at all of the Company's
    facilities, except the Hemphill plant, were largely offset by
    approximately 950 hours of utility-imposed curtailment of power output at
    the Mendota and Woodland plants in fiscal 1995, compared with no
    curtailment at these plants in fiscal 1994.

         The gross margin increased to 31% in fiscal 1995 from 26% in fiscal
    1994. Fiscal 1995 operating expenses were lower than fiscal 1994 largely
    due to reduced fuel prices at two plants in California. The effect on the
    gross profit margin of higher contractual energy rates in fiscal 1995 was
    largely offset by utility imposed curtailment of power output at the
    Mendota and Woodland plants. Lower lease expense in fiscal 1995 due to
    the conversion of the Mendota operating lease to a capital lease (Note
    13) was more than offset by higher depreciation expense on the facility.
    Despite a loss of revenues in fiscal 1994 resulting from the Whitefield
    turbine-generator damage, the gross profit margin in fiscal 1994 was
    largely unaffected due to the Company's business insurance coverage.

         General and administrative expenses as a percentage of revenues
    were 7% in fiscal 1995 and fiscal 1994.

         Interest income increased to $2.8 million in fiscal 1995 from $1.1
    million in fiscal 1994 due to interest income earned on invested proceeds
    from the Company's initial public offering (Note 5) and higher prevailing
    interest rates. Interest expense increased to $10.6 million in fiscal
    1995 from $8.4 million in fiscal 1994 largely due to the conversion of
    the Mendota lease to a capital lease, offset in part by lower outstanding
    debt at the Delano facilities.

         The effective tax rates were 35% and 32% in fiscal 1995 and fiscal
    1994, respectively. The effective tax rates were affected by the benefit
    of tax credits and loss carryforwards and the exclusion of certain income
    taxed directly to minority partners, offset in part by the effect of
    state income taxes.

         Minority interest expense in fiscal 1995 and fiscal 1994,

    Liquidity and Capital Resources

         Working capital increased to $76.2 million at September 28, 1996
    from $58.4 million at September 30, 1995. The Company had cash, cash
    equivalents, and current restricted funds of $82.2 million at September
    28, 1996, compared with $61.2 million at September 30, 1995. At September
    28, 1996 and September 30, 1995, restricted funds held in trust pursuant
    to certain lease and debt agreements totaled $18.9 million and $12.0
    million, respectively. The use of cash and cash equivalents of $7.6
    million and $6.4 million at September 28, 1996 and September 30, 1995,
    respectively, was also restricted by the terms of certain lease and
    financing agreements. These restrictions limit the ability of the
    Operating Companies to transfer funds to the Company in the form of
    dividends, loans, advances, or other distributions. In addition, until
    such time, if ever, as projections of avoided costs change, all cash
    flows from the Woodland Operating Company, other than cash distributed to
    the Company for taxes on the income of the Operating Company, will be
    restricted from distribution to the Company. During fiscal 1996, the
    Company's operating activities provided cash and restricted funds of
    $52.0 million.

         The Company received $35.9 million of net proceeds from the
    issuance of $37.0 million principal amount of noninterest-bearing
    subordinated convertible debentures in March 1996 (Note 13) and $5.0
    million of net proceeds from the issuance of its common stock in a
    private placement in June 1996 (Note 5). The Company used cash of $21.3
    million for the repayment of long-term obligations and payments under
    capital lease obligations related to two of its California plants. During
    fiscal 1996, the Company distributed $0.9 million to a minority partner
    of one of its Operating Companies.

         The Company's investing activities, other than fixed asset
    additions, have historically related to equity investments and plant
    acquisitions. Fixed asset additions and routine maintenance are generally
    financed through plant operating funds. During fiscal 1996, the Company
    used cash of $3.0 million to purchase an additional 1,500,000 shares of
    KFx common stock, bringing its total equity interest in KFx to
    approximately 14%. Pursuant to the purchase agreement, the Company has
    the right, but not the obligation, to purchase an additional 1,250,000
    shares of KFx common stock for $2.00 per share in fiscal 1997, if such
    shares are made available by KFx, and to purchase up to a total 51%
    equity interest in KFx in fiscal 2000. During fiscal 1996, the Company,
    through its Limited Partnership Agreement with KFx Wyoming, Inc.,
    expended $35.7 million for the construction of a coal-beneficiation
    facility near Gillette, Wyoming. The Company is committed to fund an
    additional $9.3 million to complete construction of the facility. Cash to
    complete construction increased approximately $6.0 million primarily due
    to changes in certain portions of the construction project. In addition,
    the Company expended $8.1 million for the purchase of the net assets of
    the biopesticides division of W.R. Grace & Co. (Note 4), and $0.9 million
    on the purchase of other property, plant and equipment.

         The Company is committed to contribute $15 million for a minority
    interest in a 185-megawatt combined cycle, steam-turbine electric
    generation facility located in Puerta Plata, Dominican Republic. Funding
    is expected to occur during calendar 1997, assuming certain conditions
    are met.

         The Company has also entered into a memorandum of understanding
    concerning a coal-fired plant under development in Gouripore, India, that
    may require the Company to make up to $60 million in equity investments
    between 1996 and 1998 should development efforts be successful. In
    addition, the Company is developing a gas-fired plant near Mysore, India,
    which if successful, would require an equity contribution from the
    Company of between $35-$60 million. In September 1996, the Company,
    through a wholly owned subsidiary, formed a joint venture with
    Marcegaglia Group of Mantova, Italy to develop, own, and operate
    biomass-fueled electric power facilities in that country, which may
    require significant equity investments if development efforts are
    successful. In January 1996, the Company, through a wholly owned
    subsidiary, entered into a joint development agreement with EMD Praha
    Spol s.r.o. in the Czech Republic, which may require significant equity
    investments if development efforts are successful.

         The Company's short-term financing requirements at September 28,
    1996 consisted primarily of $35.3 million, due in fiscal 1997, of
    principal and interest payments related to the long-term financing
    provisions for the Mendota and Delano projects. The Company expects that
    the cash flows of its Mendota, Delano I, and Delano II plants will be
    sufficient to make future lease and debt payments. The Company believes
    that its short-term liquidity needs will be met through cash flows from
    operating activities. While the Company does not currently have any firm
    available credit facilities, it does not expect to require funding for
    currently existing operations in the foreseeable future. Should the need
    for short-term funding arise, however, the Company expects that such
    funds would be available from Thermo Electron, although there is no
    agreement under which Thermo Electron is obligated to lend funds to the
    Company. The Company is in the early stages of developing projects in
    India, Italy, and the Czech Republic. Equity investments required by the
    Company for these development efforts, if successful, are uncertain, but
    may be significant. Although the Company's projects are designed to
    produce cash flow over the long-term, the Company will have to obtain
    significant additional funds from time to time to complete acquisitions
    and to meet project development requirements, including the funding of
    equity investments. As the Company acquires, invests in, or develops
    future plants, the Company expects to finance them with nonrecourse debt,
    internal funds, additional equity or through borrowings from third
    parties or Thermo Electron. While Thermo Electron has expressed its
    willingness to provide funds to the Company to help finance acquisitions
    and equity investments in future projects, the Company has no agreements
    with Thermo Electron or third parties that assure funds will be available
    on acceptable terms or at all.

    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 1997 and beyond to
    differ materially from those expressed in any forward-looking statements
    made by, or on behalf of, the Company.

    Development Risks

         Uncertainty of Project Development. The process of locating,
    developing, permitting, financing, and constructing power plants is
    complex, lengthy, and expensive. Only a small percentage of the projects
    that the Company evaluates and pursues ultimately results in operating
    projects. As a result, the Company may not recover any expenses that it
    incurs in the evaluation and development of many projects.

         Although all the plants currently operated by the Company utilize
    biomass as fuel, the Company is not currently considering the development
    of further biomass-fueled projects in the United States due to high fuel
    costs and the relatively high costs of constructing and operating
    biomass-fueled plants. The Company is considering the development of
    biomass-fueled projects internationally in countries where market
    conditions may support profitable biomass operations. The Company has
    also expanded its development focus to include international clean
    combustion opportunities, engineered clean fuels, and other
    environmentally sound technologies. In this regard, the Company has
    established offices in Calcutta and Bangalore, India and Prague, Czech
    Republic and Italy. The completion or success of these projects and new
    ventures is subject to a number of significant conditions, including
    obtaining financing, negotiating key contracts with partners and other
    third parties, and further due diligence. No assurance can be given that
    these projects or new ventures will be completed on a timely basis, or at
    all. Any failure by the Company to successfully develop new projects
    would have a material adverse effect on the future growth of the Company.

         Uncertainty Regarding K-Fuel Plant. The Company has entered into a
    limited partnership agreement with KFx Wyoming Inc., a subsidiary of KFx
    Inc. (the "Partnership"), to develop, construct, and operate a
    subbituminous coal beneficiation plant near Gillette, Wyoming. The plant
    will utilize certain patented clean coal technology (the "K-Fuel
    technology") to produce low moisture, high energy fuel with reduced
    sulfur. The total cost to construct the plant is expected to be
    approximately $48 million which the Company is committed to provide. A
    tax credit is available with respect to qualifying alternative fuels
    produced and sold by a facility placed in service before July 31, 1998
    pursuant to a binding written contract in effect before December 31,
    1996. Although the Gillette, Wyoming facility is scheduled to begin
    commercial operations in the first calendar quarter of 1997, no assurance
    can be given that it will be placed in service before 1998. If the
    Company is not eligible for this tax credit, the profitability of the
    Partnership would be materially adversely affected. In addition, the
    plant will be the first large-scale use of the K-Fuel technology, and no
                                       37PAGE
<PAGE>
    Thermo Ecotek Corporation


    Forward-looking Statements (continued)

    assurance can be given that the plant will not experience technical or
    operating problems or that the plant will be successful in producing fuel
    with the desired physical characteristics. Further, the Company currently
    has an agreement for the sale of only 33% of the plant's anticipated
    output for the first three years of operation and, at the purchaser's
    option, the plant's entire output from the fourth through the tenth year
    of operation. No assurance can be given that the purchaser of the fuel
    will exercise its option in years four through ten or that the Company
    will be able to enter into additional contracts for the sale of fuel on
    acceptable terms, or at all. Demand for the fuel produced by the plant is
    expected to result in large part from the requirement that coal-burning
    utilities comply with the future scheduled sulfur dioxide emissions
    restrictions contained in the Clean Air Act. If the fuel produced by the
    plant does not allow the achievement of desired emissions reductions, or
    if regulations relating to emissions become less restrictive in the
    future, demand for the plant's fuel output would be materially adversely
    affected.

         Uncertainty of Access to Capital. The Company has sought to finance
    the debt portion of each of its clean combustion projects in a manner
    that is substantially nonrecourse to the Company. To minimize its equity
    commitment, the Company must borrow substantial amounts from third party
    lenders. The borrowings are typically secured only by the applicable
    project assets and the capital stock of the appropriate Operating
    Company. The Company anticipates that it will require substantial
    financing to fund both the equity and debt components of future projects.
    No assurance can be given that financing for future projects will be
    available on acceptable terms, or at all. Any failure by the Company to
    obtain adequate amounts of financing on acceptable terms would have a
    material adverse effect on the future growth of the Company.

         Dependence on Terms of Power-Sales Agreement. The profitability of
    any of the Company's clean combustion facilities is heavily dependent
    upon the power-sales agreement that it has entered into with the electric
    utility or other customer. Most of the Company's existing power-sales
    agreements were obtained as a direct negotiation with the purchasing
    utility. However, in recent years, in the United States such agreements
    have increasingly been awarded as a result of competitive bidding.
    Consequently, obtaining a power-sales agreement in the United States has
    become progressively more competitive and expensive and, in many cases,
    less profitable. In the future, foreign power-sales agreements also may
    increasingly be subject to competitive bidding. In addition, the passage
    of the National Energy Policy Act of 1992 has removed certain barriers to
    entry into the independent power market by utilities and others, and is
    expected to increase competition in that market. There can be no
    assurance that power-sales agreements entered into by the Company in the
    future will not be less profitable than the power-sales agreements to
    which the Operating Companies are currently parties.

    Forward-looking Statements (continued)

         Risks Associated with Doing Business Outside the United States. The
    Company believes that the most significant growth opportunities in the
    power market exist outside of the United States. In that regard, the
    Company is pursuing projects in India, Italy, the Czech Republic, the
    Dominican Republic, and Italy, and intends to identify other countries in
    which to develop power projects. Doing business in many foreign countries
    exposes the Company to many risks that are not present in the United
    States, including political, military, privatization, currency exchange
    and repatriation risks, and higher credit risks related to the utility
    purchaser. In addition, it is possible that legal obligations may be more
    difficult for the Company to enforce in foreign countries and that the
    Company may be at a disadvantage in any legal proceeding with the local
    entity. Local laws may also limit the ability of the Company to hold a
    majority interest in some of the projects that it develops or acquires.

         Intense Competition for Projects. The Company believes that there
    are almost 200 companies that are actively engaged in the worldwide
    non-utility power market. Many of the companies in the power market have
    substantially greater financial and technical resources than the Company.
    Domestic competition in this market is expected to intensify as a result
    of deregulation at the federal and state levels, and due to the trend
    toward awarding contracts based upon competitive bidding.

         Uncertainty of Community Support. Development, construction and
    operation of a clean combustion project requires numerous environmental,
    siting, and other permits. The process of obtaining these permits can be
    lengthy and expensive. In addition, local opposition to a particular
    project can substantially increase the cost and time associated with
    developing a project, and can potentially render a project unfeasible or
    uneconomic. The Company may incur substantial costs or delays or may be
    unsuccessful in developing clean combustion projects as a result of such
    opposition.

    Operating Risks

         Expected Price Reductions under California SO#4 Contracts. The
    power-sales agreements for the Company's Woodland, Mendota, and Delano
    plants in California are so-called standard offer #4 (SO#4) contracts,
    which require Pacific Gas & Electric (PG&E), in the case of Woodland and
    Mendota, and Southern California Edison (SCE), in the case of Delano I
    and Delano II, to purchase the power output of the projects at fixed
    rates until 2000. However, with respect to Woodland and Mendota, PG&E has
    asserted that the fixed rates under its agreements will terminate
    mid-1999, although the Company disputes this assertion. Thereafter, the
    utility will pay a rate based upon its avoided costs (as determined from
    time to time by the California Public Utility Commission). Avoided-cost
    is determined pursuant to a formula that is intended to estimate the
    price that the utility would, but for its contract with the power
    producer, be paying for the same amount of energy. The rate fluctuates
    with the price of fuels and certain other factors. At present, the
    avoided-cost is substantially lower than the payments currently being
    made by PG&E and SCE. Although it is difficult to predict future levels
    of avoided-costs, based on current estimates, avoided-costs are expected
                                       39PAGE

    Thermo Ecotek Corporation


    Forward-looking Statements (continued)

    to be lower in 2000 than the rates currently being paid by PG&E and SCE.
    If the Woodland plant were to operate at projected avoided-cost levels,
    substantial losses would result primarily due to nonrecourse lease
    obligations that extend beyond 2000. The nonrecourse debt for the Mendota
    and Delano plants will be paid by 2000. Absent sufficient reductions in
    fuel prices and other operating costs, under such circumstances the
    Company would draw down power reserve funds to cover operating cash
    shortfalls and then, should such funds be depleted, either renegotiate
    its nonrecourse lease for the Woodland plant or forfeit its interest in
    the plant. Beginning in the first quarter of fiscal 1997, if projected
    avoided-costs rates remain at current levels, the Company expects to
    expense the funding of reserves required under its nonrecourse lease
    agreement at Woodland to cover projected shortfalls in lease payments
    beginning in 2000. As a result, the Company expects that the results of
    the Woodland Operating Company will be reduced to approximately
    break-even beginning in fiscal 1997. During fiscal 1996, Woodland
    contributed $5.1 million of operating income.

         Potential Decreased Power-Sales due to Power Curtailments. The
    power-sales agreements between the Woodland and Mendota Operating
    Companies and PG&E allow PG&E to curtail the quantity of power purchased
    under each of these agreements by up to approximately 1,000 hours of
    generating capacity annually. PG&E generally exercises its curtailment
    rights during periods when cheaper hydroelectric power is available,
    which generally occurs following periods of heavy rain or snow.
    Curtailment reduces the power payment received by the Operating Companies
    and, therefore, has an adverse effect on the financial results of those
    Operating Companies. During fiscal 1996, the Company experienced
    approximately 930 hours of utility imposed curtailments at each of these
    plants.

         Potential Increased Fuel Prices and Reduced Availability of Fuel.
    The profitability of the Company's plants is dependent in part upon the
    difference between the price the Company receives from its utility
    customers for power and the price the Company pays for the fuel. The
    Company has typically entered into long-term fuel supply agreements for a
    significant portion of its fuel requirements. These agreements generally
    provide for prices based upon pre-determined formulas or indexes. If fuel
    prices rise significantly, the Company will be required to pay higher
    prices on the spot market. The Company's existing power-sales agreements
    do not adjust to account for changes in the Company's fuel prices.
    Therefore, the profitability of these agreements, and any future
    power-sales agreement that do not provide for such an adjustment, could
    be materially adversely affected by increases in the Company's fuel
    prices. In addition, future fuel shortages could adversely affect the
    Company's ability to deliver power, and therefore receive payments,
    pursuant to its power-sales agreements.

         Operating Difficulties. The financial performance of each of the
    Company's plants depends to a significant extent upon the ability of each
    plant to be capable of performing at or near capacity. If a plant is
    unable to perform at these levels, payments under the power-sales
    agreement will be reduced, possibly significantly. The Company has in the
    past experienced mechanical problems with the boilers at its Mendota and
    Woodland plants and suffered major equipment damage at its Whitefield
    plant. Although the Company believes that these problems have been
    corrected, no assurance can be given that these or other plants will not
    experience operating problems in the future. No assurance can be given
    that business interruption insurance will be adequate to cover all
    potential losses, or that such insurance will continue to be available on
    reasonable terms.

         In July 1995, the Company entered into an agreement to invest $15
    million in a 185 megawatt combined cycle, steam-turbine electric
    generation facility located in Puerto Plata, Dominican Republic, owned by
    Smith/Enron Cogeneration Limited Partnership. Under the terms of the
    agreement, the Company may acquire a general and limited partnership
    interest in a partnership that holds approximately a 50% interest in the
    project. For this investment, the Company will receive a minority
    interest equivalent to a specified percentage of all project cash flow
    and profits and losses. The Company's exact percentage interest in
    Smith/Enron Cogeneration will not be finally determined until six months
    after the funding of the Company's investment, which is expected to occur
    during calendar 1997, assuming certain conditions are met. There can be
    no assurance either that the conditions to investment will be met in the
    future or that the Company will make its cash investment in the facility.

         Dependence on Utility Customers. Each of the Company's projects
    relies upon one power-sales agreement with a single electric utility
    customer for the majority, if not all, of its revenues over the life of
    the power-sales agreement. During fiscal 1996, PG&E, PSNH, and SCE
    accounted for 36%, 21%, and 36%, respectively, of the Company's revenues.
    The failure of any one utility customer to fulfill its contractual
    obligations could have a substantial negative impact on the Company. No
    assurance can be given that a particular utility will not be unwilling or
    unable, at some time, to make required payments under its power-sales
    agreements.

         Potential Earthquake Damage. The Company's California plants are
    located in areas where there is a risk of potentially significant
    earthquake activity. Projects that the Company develops in the future may
    also be located in areas, including India, where there is earthquake
    risk. The Company's earthquake insurance is not sufficient to cover all
    potential losses and there can be no assurance that such insurance will
    continue to be available on reasonable terms.

    Regulatory Risks

         Potential Rate Reduction by PSNH. PSNH is currently required to
    purchase the electricity produced by two of the Company's Operating
    Companies under long-term power purchase rate orders issued by the New
    Hampshire Public Utility Commission (NHPUC). An agreement between
    Northeast Utilities (NU), parent to PSNH, and the state of New Hampshire,
    arising from the settlement of PSNH bankruptcy proceedings, contains
    language to the effect that PSNH will seek to renegotiate some of the
    terms of certain rate orders with small power producers and the state,
    acting through NHPUC, has supported such efforts. The two affected
    Operating Companies have reached an agreement in principle with PSNH to
    settle the renegotiation of their rate orders. The settlement agreement
    is subject to the approval of the NHPUC on terms acceptable to both PSNH
    and the Operating Companies and the satisfaction of certain other
    conditions. The principal terms of the agreement generally call for the
    two affected Operating Companies to reduce the amount of power sold
    annually to PSNH to 70% of the plants' capacities, and to reduce the
    price per kilowatt paid by PSNH to $.06 per kilowatt hour, escalating
    three percent per year for the remainder of the term of the original,
    applicable rate order. In consideration of these reductions, the
    Operating Companies would receive certain cash settlement payments, paid
    over several years. The settlement, if approved and executed, is not
    expected to have a material impact on the Company's consolidated results
    of operations or financial condition. The Company expects this matter may
    reach resolution in fiscal 1997. Should the settlement not be approved
    and executed, the Company does not believe that PSNH has the right to
    take unilateral action to reduce the price of purchased power under such
    arrangements. Any such unilateral action, therefore, would result in a
    claim for damages by the Company and could be the subject of lengthy
    litigation. An adverse resolution of any such claim could materially
    affect the Company's operations and cash flows.

         Potential Effects of Loss of QF Status or Changes to PURPA. The
    Company 's existing facilities are subject to the provisions of various
    laws and regulations, including the Public Utility Regulatory Policies
    Act of 1978, as amended (PURPA). PURPA provides to Qualifying Facilities
    (QFs) certain exemptions from substantial federal and state legislation,
    including regulation as public utilities. PURPA also requires electric
    utilities to purchase electricity generated by QFs at prices not
    exceeding the costs that would otherwise have been incurred by the
    purchasing utilities in generating the own electricity or in purchasing
    it from other sources (known as "avoided-cost"). Any future changes to
    PURPA could have a material adverse effect on the Company.

         The Public Utility Holding Company Act of 1935 (PUHCA) regulates
    public utility holding companies and their subsidiaries. The Company is
    not and will not be subject to regulation as a holding company under
    PUHCA as long as the domestic power plants it operates are QFs under
    PURPA. If a power plant were to lose its QF status, the Operating Company
    owning or leasing that plant could become a public utility company, which
    could result in the Company becoming a public utility holding company. In
    addition, loss of QF status, regardless of the Company's ability to avoid
                                       42PAGE

    Forward-looking Statements (continued)

    public utility holding company status, could be a default under many of
    the Company's facility lease and power-sales agreements. In the event of
    any such default, the other parties to such agreements could seek various
    remedies against the Company or could seek to renegotiate such agreements
    on terms more favorable to such parties.

         Potential Increased Competition Due to Regulatory Changes. The
    Company believes that certain regulatory changes are likely to have a
    significant impact on the domestic power market over the next five years.
    The National Energy Policy Act of 1992 exempts a new class of facilities
    from certain federal utility regulation and liberalizes access for
    non-utility generators to the utility power transmission grid. In
    addition, many states are considering the elimination of many of the
    regulations that currently limit the ability of power generators to
    negotiate power-sales agreements directly with industrial and commercial
    customers. The Company believes that the effect of these regulatory
    changes will be to increase competition for the sale of power.

         Limitations Imposed by Environmental Regulation. Federal, state,
    and local environmental laws govern air emissions and discharges into
    water and the generation, transportation, storage, and treatment and
    disposal of solid and hazardous waste. These laws establish standards
    governing most aspects of the construction and operation of the Company's
    facilities, and often require multiple governmental permits before these
    facilities can be constructed, modified, or operated. There can be no
    assurance that all required permits will be issued for the Company's
    projects under development or for future projects, or that the
    requirements for continued environmental regulatory laws and policies
    governing their enforcement may change, requiring new technology or
    stricter standards for the control of discharges of air or water
    pollutants, or for solid or hazardous waste or ash handling and disposal.
    Such future developments could affect the manner in which the Company
    operates its plants and could require significant additional expenditures
    to achieve compliance with such requirements. It is possible that
    compliance may not be technically or economically feasible.

    Risks Associated with Biopesticides Business

         Uncertainty of Market Penetration. The Company's sales growth is
    dependent on the penetration of its products into new markets. The
    primary competition to the Company's products are chemical pesticides,
    and the Company must educate customers that the cost effectiveness and
    efficacy of the Company's products are superior to chemical pesticides in
    order to gain acceptance for application on new crop types in different
    parts of the world. No assurance can be given that the Company's products
    will gain increased acceptance in new market segments.

         Need for Regulatory Approval. The Company's products cannot be sold
    unless the Environmental Protection Agency grants the Company a
    registration for each pesticide product it intends to manufacture or
    sell. The Company must submit extensive toxicological studies and results
    of field testing as well as other studies to the EPA to apply for a
    product registration. The EPA may take many years to approve a
                                       43PAGE

    Forward-looking Statements (continued)

    registration application. Pesticide registrations under state laws and
    regulations must also be obtained. In addition, pesticide registrations
    must be obtained from foreign governments before the Company's products
    can be sold in the country, and these countries may also require costly
    and extensive studies to support the registration application. There is
    no assurance that the EPA, states, or foreign governments will grant any
    pesticide registrations to the Company. Pesticide registrations may also
    be revoked if the Company violates regulations regarding the
    manufacturing, sale, or labeling of the Company's products.

         Dependence on Proprietary Technology. The Company's products
    incorporate patented, licensed and unlicensed proprietary technology.
    There is no assurance that the Company's patents or licenses will provide
    sufficient protection or commercial benefits, or that competitors will
    not independently develop substantially equivalent or more economical and
    effective technology. There is also no assurance that foreign governments
    will protect the Company's patent rights to the same extent as in the
    U.S. or that the Company's unpatented trade secrets will remain
    confidential or will not be discovered by competitors. There is no
    assurance that the Company will be able to develop new proprietary
    technology to provide the Company with new products which cannot be
    offered by the Company's competitors.

         Highly Competitive Markets and Technological Change. The markets in
    which the Company operates are highly competitive and subject to rapid
    technological change. Many of the Company's products are in research and
    development, testing, or early marketing stages. Many of the Company's
    competitors are large chemical companies with greater financial,
    marketing, and technological resources than the Company. There is no
    assurance that competitors will not develop new products that will render
    the Company's products noncompetitive.

         Product Liability. Application of the Company's pesticide products
    to crops and farm lands could expose the Company to product liability
    claims. Product liability claims could result in Company exposure for
    crop damage or personal injury. Run-off of excess concentrations of
    pesticide products could also expose the Company to claims and
    liabilities for water pollution, including governmental fines and
    penalties.

         Reliance on Third Party Manufacturers and Producers. The Company
    relies on overseas producers of the raw materials for its products and on
    third party toll manufacturers to manufacture and package the raw
    material into a saleable product. There is no assurance that the Company
    will have an uninterrupted supply of raw material or that producers and
    toll manufacturers will produce the products at competitive prices.

    Other Risks

         Significant Quarterly Fluctuations in Operating Results. The
    Company's operating results fluctuate significantly from quarter to
    quarter based on a number of factors, primarily seasonal energy demand in
    California, which results in higher payments under the Company's
    California power-sales agreements in the months of May through October,
    and lower payments during the remainder of the year, and seasonal demand
    for its biopesticide products. The Company historically has operated at a
    loss or marginal profitability during its second fiscal quarter due to
    the rate structure under these agreements. In addition, the Company's
    operating results can be affected by utility imposed curtailments or by
    any operating problems that cause a plant to operate at less than normal
    capacity, and with respect to its biopesticide business, by agricultural
    conditions such as pest pressure and infestation, amount of rain, the
    occurrence of natural resistance factors, and the increase or decrease in
    agricultural plantings and produce prices.

         Limitation on Access to Operating Company Assets and Cash Flow. The
    Company's operations are conducted through the Operating Companies, and
    the Company's cash flow is contingent on the ability of the Operating
    Companies to make dividends or other distributions to the Company. The
    terms of certain leases and financial agreements to which the Operating
    Companies are parties require that certain funds be held in trust and
    that certain funds be restricted from distribution to the Company. As of
    September 28, 1996, approximately $7.6 million of the Company's cash and
    cash equivalents was restricted from distribution by the terms of certain
    operating companies lease and financing agreements. In addition, until
    such time, if ever, as projections of avoided-cost change, all cash flows
    from the Woodland operation, other than cash required for tax
    distribution, will be restricted from distribution to the Company. The
    inability of the Company to receive distributions from the Operating
    Companies could have a material adverse effect on the future growth of
    the Company.

         As of November 22, 1996, the Registrant had 778 holders of record
    of its common stock. This does not include holdings in street or nominee
    names. The closing market price on the American Stock Exchange for the
    Registrant's common stock on November 22, 1996, was $14 3/4 per share.

    Dividend Policy

         The Registrant has never paid cash dividends because its policy has
    been to use earnings to finance expansion and growth. Payment of
    dividends will rest within the discretion of the Board of Directors and
    will depend upon, among other factors, the Registrant's earnings, capital
    requirements, and financial condition. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations" for a
    discussion of certain restrictions applicable to the use of certain
    funds.
