                   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 29, 1996,
   the results of operations for the three-month periods ended June 29, 1996
   and July 1, 1995, and the cash flows for the three-month periods ended June
   29, 1996 and July 1, 1995. Interim results are not necessarily indicative
   of results for a full year.

        The consolidated balance sheet presented as of March 30, 1996, has
   been derived from the consolidated financial statements that have been
   audited by the Company's independent public accountants. The consolidated
   financial statements and notes are presented as permitted by Form 10-Q and
   do not contain certain information included in the annual financial
   statements and notes of the Company. The consolidated financial statements
   and notes included herein should be read in conjunction with the financial
   statements and notes included in the Company's Annual Report on Form 10-K
   for the fiscal year ended March 30, 1996, filed with the Securities and
   Exchange Commission.

        Certain amounts in fiscal 1996 have been reclassified to conform to
   the fiscal 1997 financial statement presentation. Certain of these
   reclassifications are required to present consistent classification of
   expenses within the Company's consulting and design services business.

   2.   Subordinated Convertible Debentures

        In May 1996, the Company issued and sold $115.0 million principal
   amount of 4 5/8% subordinated convertible debentures due 2003 for net
   proceeds of $112.5 million. The debentures are convertible into shares of
   the Company's common stock at a price of $15.90 per share and are
   guaranteed on a subordinated basis by Thermo Electron Corporation (Thermo
   Electron). The Company has agreed to reimburse Thermo Electron in the event
   Thermo Electron is required to make a payment under the guarantee. In May
   1996, the Company repaid its $15.0 million and $35.0 million promissory
   notes to Thermo Electron with proceeds from the offering.


   Item 2 - Management's Discussion and Analysis of Financial Condition and
            Results of Operations

   Overview

        The Company is a provider of environmental services and infrastructure
   planning and design, encompassing a range of specializations within the
   remediation and recycling, consulting and design, and laboratory-testing
   industries. The Company also provides metal-treating services and
   thermal-processing systems used to treat primary metals and metal parts.

                              THERMO TERRATECH INC.

   Overview (continued)

   The Company's environmental services businesses are affected by several
   factors, particularly, extreme weather variations, government spending, and
   regulation of remediation activities.

        Remediation and Recycling - The Company's majority-owned Thermo
   Remediation Inc. (Thermo Remediation) subsidiary operates a network of
   soil-remediation centers, serving customers in more than a dozen states on
   the East and West coasts by providing thermal treatment of soil to remove
   and destroy petroleum contamination caused by leaking underground and
   aboveground storage tanks, spills, and other sources. In December 1995,
   Thermo Remediation acquired Remediation Technologies, Inc. (ReTec), which
   provides integrated environmental services such as remediation of
   industrial sites contaminated with organic wastes and residues. Through its
   Thermo Nutech subsidiary, Thermo Remediation provides services to remove
   radioactive contaminants from sand, gravel, and soil, as well as health
   physics, radiochemistry laboratory, and radiation dosimetry services. In
   addition, Thermo Remediation's Thermo Fluids subsidiary offers
   fluids-recycling services including waste motor oil and wastewater
   treatment throughout Arizona, Nevada, and in neighboring states. The
   Company's majority-owned Thermo EuroTech N.V. (Thermo EuroTech) subsidiary,
   located in the Netherlands, provides wastewater treatment services as well
   as services to test, remove, and install underground storage tanks. Through
   its North Refinery subsidiary, Thermo Eurotech specializes in converting
   "off-spec" and contaminated petroleum fluids into usable oil products.

        Consulting and Design - The Company's wholly owned Killam Associates
   subsidiary provides environmental consulting and engineering services and
   specializes in wastewater treatment and water resources management. The
   Company's wholly owned Bettigole Andrews & Clark and Normandeau Associates
   subsidiaries provide both private and public sector clients with a range of
   consulting services that address transportation planning and design, and
   natural resource management issues, respectively. 

        Laboratory Testing - The Company's wholly owned Thermo Analytical
   subsidiary operates a network of analytical laboratories that provide
   environmental testing services to commercial and government clients
   throughout the U.S. The May 1995 acquisition of Lancaster Laboratories,
   Inc. (Lancaster Laboratories) expanded the Company's range of contract
   services beyond environmental testing to the pharmaceutical- and
   food-testing industries.

        Metal Treating - The Company performs metallurgical processing
   services using thermal-treatment equipment at locations in California and
   Minnesota. The Company also designs, manufactures, and installs advanced
   custom-engineered, thermal-processing systems through its equipment
   division located in Michigan.

   Results of Operations

   First Quarter Fiscal 1997 Compared With First Quarter Fiscal 1996

        Total revenues in the first quarter of fiscal 1997 increased 34% to
   $66.9 million from $49.9 million in the first quarter of fiscal 1996.
   Revenues from remediation and recycling services were $27.5 million in
   fiscal 1997, compared with $15.4 million in fiscal 1996, primarily due to
   the inclusion of $10.5 million in revenues from ReTec, which was acquired
   in December 1995, an increase in revenues at Thermo EuroTech and, to a
   lesser extent, higher revenues from a long-term environmental restoration
   contract for the U.S. Department of Energy's (DOE's) Hanford site (Hanford)
   and related health physics services. These increases were largely offset by
   a decrease in radiochemistry laboratory work, reflecting a reduction in
   spending at the DOE and delays in federal government budget appropriations.
   Revenues from soil-remediation services decreased 8% resulting from
   declines in the volume and price of soil processed due to competitive
   pricing pressures and ongoing regulatory uncertainties in several states.
   Revenues from consulting and design services increased to $21.5 million in
   fiscal 1997 from $19.8 million in fiscal 1996, primarily due to increased
   revenues from two major contracts, offset in part by lower revenues from
   federal government contracts, reflecting a reduction in spending and delays
   in budget appropriations. Revenues from laboratory-testing services,
   excluding the radiochemistry laboratory services included in remediation
   and recycling services, increased to $8.8 million in fiscal 1997 from $7.5
   million in fiscal 1996, largely due to the inclusion of an additional $2.8
   million of revenues from Lancaster Laboratories, acquired in May 1995,
   offset in part by a decline in revenues due to reduced federal spending.
   Metal-treating revenues increased to $9.1 million in fiscal 1997 from $7.2
   million in fiscal 1996, primarily due to an increase in demand for
   thermal-processing equipment.

        The gross profit margin decreased to 19% in the first quarter of
   fiscal 1997 from 24% in the first quarter of fiscal 1996, primarily due to
   the inclusion of lower-margin revenues from ReTec and a decrease in gross
   profit margins for remediation and recycling services due to competitive
   pricing pressures. These decreases were offset in part by higher gross
   profit margins from metal-treating services resulting from an increase in
   revenues.

        Selling, general and administrative expenses as a percentage of
   revenues decreased to 13% in the first quarter of fiscal 1997 from 17% in
   the first quarter of fiscal 1996, primarily due to efficiencies associated
   with an increase in revenues and a decline in expenses related to the
   consolidation of administrative functions within the consulting and design
   services business.

        Interest income increased to $1.6 million in the first quarter of
   fiscal 1997 from $1.4 million in the first quarter of fiscal 1996,
   primarily due to an increase in invested amounts as a result of the
   Company's May 1996 issuance of 4 5/8% subordinated convertible debentures
   (Note 2). Interest expense increased to $3.1 million in fiscal 1997 from
   $2.3 million in fiscal 1996, primarily due to the Company's May 1996
   issuance of subordinated convertible debentures and Thermo Remediation's

                              THERMO TERRATECH INC.

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

   May 1995 issuance of 4 7/8% subordinated convertible debentures, offset in
   part by a decrease in interest expense due to the repayment of promissory
   notes to Thermo Electron Corporation (Thermo Electron) with proceeds from
   the Company's May 1996 issuance of subordinated convertible debentures
   (Note 2).

        Equity in earnings of unconsolidated subsidiary in the first quarter
   of fiscal 1997 represents ReTec's proportionate share of income from a
   joint venture.

        During the first quarter of fiscal 1996, the Company recorded gains of
   $2.7 million from the sale of stock by subsidiary.

        The effective tax rates were 47% and 19% in the first quarter of
   fiscal 1997 and 1996, respectively. The effective tax rate in fiscal 1997
   was higher than the statutory federal income tax rate primarily due to
   nondeductible amortization of cost in excess of net assets of acquired
   companies and the impact of state income taxes. The effective tax rate in
   fiscal 1996 was lower than the statutory federal income tax rate primarily
   due to the nontaxable gain on issuance of stock by subsidiary. 

        Minority interest expense decreased to $0.2 million in the first
   quarter of fiscal 1997 from $0.4 million in the first quarter of fiscal
   1996, due to a reduction in earnings from the Company's majority-owned
   subsidiaries.

   Liquidity and Capital Resources

        Consolidated working capital, including cash, cash equivalents, and
   short-term available-for-sale investments, increased to $106.3 million at
   June 29, 1996 from $67.4 million at March 30, 1996. Cash, cash equivalents,
   and short- and long-term available-for-sale investments were $101.5 million
   at June 29, 1996, compared with $40.3 million at March 30, 1996. Of the
   $101.5 million balance at March 30, 1996, $33.7 million was held by Thermo
   Remediation and the remainder by the Company and its wholly owned
   subsidiaries. In addition, at June 29, 1996 the Company had $24.7 million
   of long-term held-to-maturity investments, compared with $24.3 million at
   March 30, 1996. During the first quarter of fiscal 1997, $3.2 million of
   cash was provided by operating activities. In the first quarter of fiscal
   1997, the Company used cash of $3.0 million primarily to fund an increase
   in unbilled contract costs and fees due to an increase in thermal-
   processing equipment contracts, an increase in remediation contracts at
   ReTec, as well as an increase in consulting and design services contracts.

        In May 1996, the Company issued and sold $115.0 million principal
   amount of 4 5/8% subordinated convertible debentures due 2003 for net
   proceeds of $112.5 million (Note 2). The debentures are guaranteed on a
   subordinated basis by Thermo Electron. The Company has agreed to reimburse
   Thermo Electron in the event Thermo Electron is required to make a payment
   under the guarantee. In May 1996, the Company repaid its $15.0 million and
   $35.0 million promissory notes to Thermo Electron with proceeds from the
   offering.

                              THERMO TERRATECH INC.

   Liquidity and Capital Resources (continued)

        In the first quarter of fiscal 1997, the Company expended $4.4 million
   on purchases of property, plant and equipment. During the remainder of
   fiscal 1997, the Company expects to expend $5.6 million for purchases of
   property, plant and equipment. 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.
   The Company believes that it has adequate resources to meet the financial
   needs of its current operations for the foreseeable future.
