                   Notes to Consolidated Financial Statements

    1.  General

        The interim consolidated financial statements presented have been
    prepared by Thermo TerraTech Inc. (the Company) without audit and, in the
    opinion of management, reflect all adjustments of a normal recurring
    nature necessary for a fair statement of the financial position at June
    28, 1997, and the results of operations and cash flows for the
    three-month periods ended June 28, 1997, and June 29, 1996. Interim
    results are not necessarily indicative of results for a full year.

        The consolidated balance sheet presented as of March 29, 1997, has
    been derived from the consolidated financial statements that have been
    audited by the Company's independent public accountants. The consolidated
    financial statements and notes are presented as permitted by Form 10-Q
    and do not contain certain information included in the annual financial
    statements and notes of the Company. The consolidated financial
    statements and notes included herein should be read in conjunction with
    the financial statements and notes included in the Company's Annual
    Report on Form 10-K for the fiscal year ended March 29, 1997, filed with
    the Securities and Exchange Commission.

    2.  Acquisitions

        In May 1997, the Company purchased a controlling interest in The
    Randers Group Incorporated (Randers), a provider of design engineering,
    project management, and construction services for industrial clients in
    the manufacturing, pharmaceutical, and chemical-processing industries.
    The Company purchased 7,100,000 shares of Randers common stock from
    certain members of Randers' management, and 420,000 shares from Thermo
    Power Corporation, an affiliate of the Company, at a price of $0.625 per
    share, for an aggregate cost of approximately $4.7 million. Following
    these transactions, the Company owns approximately 53.3% of Randers'
    outstanding common stock. In addition, Thermo Electron Corporation owns
    approximately 8.9% of Randers' outstanding common stock. Randers had
    revenues of $12.4 million in calendar 1996.

        In addition, during the first quarter of fiscal 1998, the Company's
    Thermo Remediation Inc. subsidiary made an acquisition for an aggregate
    purchase price of $1.6 million. 

        These acquisitions have been accounted for using the purchase method
    of accounting and their results of operations have been included in the
    accompanying financial statements from their respective dates of
    acquisition. The aggregate cost of these acquisitions exceeded the
    estimated fair value of the acquired net assets by $3.1 million, which is
    being amortized over 40 years. Allocation of the purchase price for these
    acquisitions was based on estimates of the fair value of the net assets
    acquired and is subject to adjustment upon finalization of the purchase
    price allocation. Pro forma data is not presented since these
    acquisitions were not material to the Company's results of operations.

                              THERMO TERRATECH INC.

    2.  Acquisitions (continued)

        The Company has also entered into a letter of intent to transfer its
    wholly owned engineering and consulting businesses to Randers in exchange
    for newly issued shares of Randers common stock. The exact price for
    these businesses is still under negotiation, but in no event would be
    less than the book value of the transferred businesses as of the closing
    of the transfer. The number of new shares of Randers common stock to be
    issued to the Company would equal the agreed price divided by $0.625.

        The transfer is subject to several conditions, including completion
    by Randers of its due diligence investigation, receipt of an opinion from
    an investment bank that the transaction is fair to Randers from a
    financial point of view, approval of the transaction by Randers'
    shareholders, and receipt of all required regulatory approvals, including
    continued listing of Randers' common stock on the American Stock Exchange
    following the transaction.

    3.  Presentation

        Certain amounts in fiscal 1997 have been reclassified to conform to
    the presentation in the fiscal 1998 financial statements.

    Results of Operations

    First Quarter Fiscal 1998 Compared With First Quarter Fiscal 1997

        Total revenues in the first quarter of fiscal 1998 increased to $72.5
    million from $67.6 million in the first quarter of fiscal 1997. Revenues
    from remediation and recycling services increased to $30.7 million in
    fiscal 1998 from $27.9 million in fiscal 1997, due to the inclusion of

<PAGE>
                              THERMO TERRATECH INC.

    First Quarter Fiscal 1998 Compared With First Quarter Fiscal 1997
    (continued)

    $6.6 million of revenues from IEM Sealand and TriTechnics, acquired in
    September 1996 and May 1997, respectively. Revenues from soil-remediation
    services decreased 31% resulting both from declines in the volume of soil
    processed due to overcapacity in the industry and from competitive
    pricing pressures. The Company expects this trend to continue for the
    foreseeable future. Revenues from Thermo EuroTech decreased 42%,
    primarily due to the sale of its J. Amerika division in the fourth
    quarter of fiscal 1997. Revenues from consulting and design services
    decreased slightly to $20.6 million in fiscal 1998 from $21.5 million in
    fiscal 1997. The inclusion of $2.9 million of revenues from Carlan and
    Randers, acquired in November 1996 and May 1997, respectively, was more
    than offset by a decrease in revenues due to the completion of two major
    contracts in fiscal 1997. Revenues from laboratory-testing services,
    excluding radiochemistry laboratory services included in remediation and
    recycling services, remained relatively unchanged at $9.4 million in
    fiscal 1998 and $9.3 million in fiscal 1997. Metal-treating revenues
    increased to $12.1 million in fiscal 1998 from $9.9 million in fiscal
    1997, primarily due to an increase in demand for thermal-processing
    equipment at existing businesses.

        The gross profit margin remained unchanged at 20% in the first
    quarter of fiscal 1998 and 1997. The gross profit margin was favorably
    affected by a change in sales mix to higher-margin contracts in the
    Company's consulting and design services business. This increase was
    offset by a decrease in gross profit margin from remediation and
    recycling services primarily due to lower margins on soil processed
    resulting from competitive pricing pressures and lower volumes of soil
    processed at the Company's traditionally higher-margin soil-remediation
    centers. The gross profit margin from remediation and recycling services
    also decreased due to the inclusion of lower-margin revenues from IEM
    Sealand, acquired in September 1996. 

        Selling, general, and administrative expenses as a percentage of
    revenues remained unchanged at 14% in the first quarter of fiscal 1998
    and 1997.

        Interest income decreased to $1.4 million in the first quarter of
    fiscal 1998 from $1.6 million in the first quarter of fiscal 1997, as a
    result of lower average investment balances following the repurchase of
    Company and subsidiaries common stock, as well as the acquisition of
    Randers and TriTechnics (Note 2). Interest expense remained unchanged at
    $3.1 million in the first quarter of fiscal 1998 and 1997.

        Other income of $0.2 million in the first quarter of fiscal 1998
    represents a gain on the sale of certain equipment.

        The effective tax rate was 47% in the first quarter of fiscal 1998
    and 1997. The effective tax rate exceeded the statutory federal income
    tax rate primarily due to the nondeductible amortization of cost in
    excess of net assets of acquired companies and the impact of state income
    taxes.

    First Quarter Fiscal 1998 Compared With First Quarter Fiscal 1997
    (continued)

        Minority interest expense increased slightly to $0.3 million in the
    first quarter of fiscal 1998 from $0.2 million in the first quarter of
    fiscal 1997, due to net higher earnings from the Company's majority-owned
    subsidiaries and the addition of minority interest expense related to
    Randers (Note 2).

    Liquidity and Capital Resources

        Consolidated working capital decreased to $67.8 million at June 28,
    1997, from $77.3 million at March 29, 1997. Cash, cash equivalents, and
    short-term available-for-sale investments were $19.4 million at
    June 28, 1997, compared with $81.6 million at March 29, 1997. Of the
    $19.4 million balance at June 28, 1997, $12.8 million was held by Thermo
    Remediation and the remainder by the Company and its wholly owned
    subsidiaries. In addition, at June 28, 1997, the Company had $26.5
    million of short-term held-to-maturity investments, compared with $26.1
    million of short- and long-term held-to-maturity investments at March 29,
    1997. During the first three months of fiscal 1998, $9.0 million of cash
    was used in operating activities. The Company funded an $11.2 million
    increase in unbilled contract costs and fees primarily due to higher
    revenues at Thermo Remediation's IEM Sealand and ReTec businesses, the
    timing of billings due to contract milestones at The Killam Group, and an
    increase in thermal-processing equipment contracts. 

        Excluding available-for-sale investments activity, the Company's
    investing activities in the first quarter of fiscal 1998 primarily
    consisted of acquisitions and capital additions. In May 1997, the Company
    purchased a controlling interest in Randers, a provider of design
    engineering, project management, and construction services for industrial
    clients in the manufacturing, pharmaceutical, and chemical-processing
    industries, for approximately $4.7 million (Note 2). In addition, in May
    1997, Thermo Remediation acquired TriTechnics for approximately $1.6
    million in cash (Note 2). The Company also expended $5.0 million for
    purchases of property, plant, and equipment in the first quarter of
    fiscal 1998. The Company expects to expend approximately $13.6 million on
    purchases of property, plant, and equipment during the remainder of
    fiscal 1998.

        In the first quarter of fiscal 1998, the Company's financing
    activities used cash of $44.0 million, primarily resulting from the
    repayment of a $38.0 million promissory note to Thermo Electron
    Corporation (Thermo Electron) and the repurchase of Company and
    subsidiaries common stock. The Boards of Directors of the Company and
    Thermo Remediation each authorized the repurchase, through August 23,
    1997, and September 10, 1997, respectively, of up to $10.0 million of
    their own securities.  Through June 28, 1997, the Company and Thermo
    Remediation had expended $9.9 million and $10.0 million, respectively,
    under these authorizations, of which $3.2 million and $1.7 million,
    respectively, was expended in fiscal 1998. In July 1997, Thermo
    Remediation's Board of Directors authorized the repurchase, through July
    24, 1998, of up to an additional $5.0 million of its own securities. Any
    such purchases would be funded from working capital.

    Liquidity and Capital Resources (continued)

        The Company has no material commitments for the acquisition of
    businesses or for capital expenditures. Such expenditures will largely be
    affected by the number and size of the complementary businesses that can
    be acquired or developed during the year. Thermo Electron has expressed
    its willingness to lend funds to the Company for major capital
    expenditures and potential acquisitions that may occur in the foreseeable
    future.
