        This Amendment No. 3 to Schedule 13D amends and restates the entire
   text of the Schedule 13D, as previously amended, previously filed by
   Thermo Electron Corporation and its subsidiaries Thermo Power Corporation
   and Thermo TerraTech Inc. relating to shares of common stock, par value
   $.0001 per share (the "Common Stock"), of The Randers Group Incorporated.


   Item 1.  Security and Issuer.
   -------  --------------------

        This Schedule 13D relates to the shares of Common Stock (the

        This Schedule 13D is being filed by (i) Thermo Electron Corporation
   ("Thermo Electron"), (ii) Thermo Power Corporation ("Thermo Power") and

   (c) present principal occupation or employment and the name, principal
   business and address of any corporation or other organization in which

   of any of the Reporting Persons, has been convicted in a criminal
   proceeding.

        During the last five years, none of the Reporting Persons, nor (to

   of a judicial or administrative body of competent jurisdiction which
   resulted in a judgment, decree or final order (i) enjoining future
   violations of, or prohibiting or mandating activities subject to, federal
   or state securities laws or (ii) finding a violation with respect to such
   laws.

        Marshall J. Armstrong, Senior Vice President, Government Affairs, of
   Thermo Electron and a director of Thermo Power, may also be deemed to
   beneficially own 10,000 Shares of the Issuer for purposes of Rule
   13d-3(a).  The Shares referred to in this report as beneficially owned by
   Mr. Armstrong are owned by his wife and adult son whom he supports.  Mr.
   Armstrong disclaims beneficial ownership of these Shares.  Mr.
   Armstrong's business address is Thermo Electron Corporation, 81 Wyman
   Street, Waltham, Massachusetts  02254.  Mr. Armstrong is a citizen of the
   United States.

   Item 3.  Source and Amount of Funds or Other Consideration.
   -------  --------------------------------------------------

        Of the Shares of the Issuer owned by the Reporting Persons and
   referred to in Item 5, Thermo Electron purchased 1,000,000 Shares
   directly from the Issuer for $1,000,000 in March, 1991, and 260,000
   Shares in open market purchases at various times for aggregate
   consideration of $172,716 (including brokerage commissions).  Thermo
   Power acquired an additional 420,000 Shares in January, 1994 pursuant to
   the exercise of an option granted by a former officer and director of the
   Issuer, for an aggregate exercise price of $428,904.  Thermo TerraTech
   purchased 7,100,000 Shares from certain members of the Issuer's
   management and the 420,000 Shares owned by Thermo Power on May 12, 1997,
   at a price of $.625 per Share, for aggregate consideration equal to
   $4,700,000.  All funds used to purchase these Shares came out of the
   working capital of Thermo Electron, Thermo Power and/or Thermo TerraTech,
   as the case may be, and there were no borrowings in connection with such
   purchases.

        The Shares purchased by family members of Marshall J. Armstrong were
   purchased in March, 1991 for an aggregate consideration of $10,500
   (including brokerage commissions).  The funds used to purchase such
   Shares were personal funds and there were no borrowings in connection
   with such purchases.

   Item 4.  Purpose of Transaction.
   -------  -----------------------

        On May 12, 1997,  Thermo TerraTech purchased a controlling interest
   in the Issuer.  Thermo TerraTech purchased 7,100,000 Shares from certain
PAGE
<PAGE>


        CUSIP No. 752333 10 4                                Page 7 of 13


   members of the Issuer's management and 420,000 Shares from Thermo Power.
   Following these transactions, Thermo TerraTech owns approximately 53.3%
   of the Issuer's outstanding Common Stock.  In addition, Thermo Electron
   owns approximately 8.9% of the Issuer's Common Stock.

        Simultaneously with such transactions, Thermo TerraTech entered into
   a letter of intent to transfer its wholly owned engineering and
   consulting businesses, including the Killam group of companies, to the
   Issuer in exchange for newly issued shares of the Issuer's Common Stock.
   The exact price for these businesses is still under negotiation, but, in
   any event, would not be less than the book value of the transferred
   businesses as of the closing of the transfer.  The number of new shares
   of the Issuer' s Common Stock to be issued to Thermo TerraTech would
   equal the agreed price divided by $.625.  The transfer is expected to be
   completed in approximately 90 days, and is subject to several conditions,
   including completion by the Issuer of its due diligence investigation,
   receipt of an opinion from an investment bank that the transaction is
   fair to the Issuer from a financial point of view, approval of the
   transaction by the Issuer's shareholders, and receipt of all required
   regulatory approvals, including continued listing of the Issuer's Common
   Stock on the American Stock Exchange following the transaction.

        The persons identified in response to Item 2 will continue to
   consider various relevant factors, including their evaluation of the
   Issuer's business, prospects and financial condition, amounts and prices
   of available securities of the Issuer, the market for the Issuer's
   securities, other opportunities available to such persons and general
   market and economic conditions.  Depending on such factors, such persons
   may either make additional purchases of Shares or other securities of the
   Issuer in such manner and in such amounts as they determine to be
   appropriate, or such persons may decide to sell all or part of their
   Shares.

        The Board of Directors of the Issuer has named Emil C. Herkert, a
   vice president of Thermo TerraTech and the president of Thermo
   TerraTech's wholly owned engineering and consulting businesses, as its
   chief executive officer.  Thermo TerraTech reserves the right to cause
   changes in the capitalization and/or the present board of directors
   and/or management of the Issuer.  Except as set forth in this Item 4,
   however, none of the Reporting Persons, nor, to the Reporting Persons'
   knowledge, any of the executive officers or directors of any of the
   Reporting Persons, has any current plans or proposals which relate to or
   would result in any of the actions specified in clauses (a) through (j)
   of Item 4 of Schedule 13D.

   Item 5.  Interest in Securities of the Issuer.
   -------  -------------------------------------

        (a)  As of May 12, 1997, the Reporting Persons collectively
   beneficially owned 8,780,000 Shares, or 62.2%, of the Issuer's
   outstanding Common Stock.  The Shares reported beneficially owned by
   Thermo Electron include the 7,520,000 Shares (53.3%) owned by its
   83.3%-subsidiary, Thermo TerraTech.  Certain family members of Marshall
   J. Armstrong beneficially own 10,000 Shares, or .07%, of the Issuer's
   outstanding Common Stock.  Mr. Armstrong disclaims beneficial ownership
   of these Shares.  To the knowledge of the Reporting Persons, no other
   executive officer or director of any of the Reporting Persons
   beneficially owns any Shares of the Issuer.

        (b)  Thermo Electron has the sole power to vote and dispose of the
   Shares owned by it.  Thermo TerraTech has the sole power to vote and
   dispose of the Shares owned by it.  By virtue of its 83.3% ownership of
   Thermo TerraTech, Thermo Electron may be deemed to have the power to vote
   and dispose of the Shares owned by Thermo TerraTech.  However, the
   Reporting Persons disclaim the existence of a group among themselves for
   purposes of this Schedule 13D.  As described in Item 2, Mr. Armstrong may
   be deemed to have the sole power to vote and dispose of the 10,000 Shares
   identified in the last paragraph of Item 2.

        (c)  Except as described in this Amendment, during the past 60 days
   none of the Reporting Persons have effected any transactions in the
   Shares. 

        To the knowledge of the Reporting Persons, no other executive
   officer or director of any of the Reporting Persons has effected any
   transactions in the Shares during the past 60 days.

        (d)  Not applicable.

        (e)  Not applicable.

   Item 6.  Contracts, Arrangements, Understandings or Relationships with

        and shall be deemed not to qualify any paragraph of this Article
        3 not so specifically identified.  Each individual representation
        and warranty contained herein shall be interpreted and enforced
        separately and no representation or warranty contained herein
        shall be construed as limiting any other representation and
        warranty contained herein. The Buyer shall be assumed to have

        of the transactions contemplated hereby will (a) conflict with or
        result in a violation, breach, termination or acceleration of, or
        default under (or would result in such a violation, breach,
        termination, acceleration or default with the giving of notice or
        passage of time, or both) any of the terms, conditions or
        provisions of any note, bond, mortgage, indenture, agreement or
        other instrument or obligation to which the Seller is a party or

        Seller, subject to compliance with, or exemptions from,
        applicable federal and state securities laws.  The Seller holds

        -----
        existing and in corporate and tax good standing under the laws of
        the State of Delaware.  The Company is duly qualified to conduct
        business and is in corporate and tax good standing as a foreign
        corporation in each jurisdiction in which the failure to so

        business, financial condition, results of operations or future
        prospects of the Company and the Subsidiaries (as defined in
        Section 3.6(b) below), taken as a whole (a "Material Adverse
        Effect").  The Company has all requisite corporate power and
        authority to carry on the businesses in which it is engaged and
        to own and use the properties owned and used by it.  The Sellers
        have caused the Company to furnish to the Buyer true and complete
        copies of the Company's Certificate of Incorporation and Bylaws,
        each as amended and as in effect on the date hereof.  Each
        amendment to the Company's Certificate of Incorporation has been
        duly adopted by all requisite director and shareholder action and
        in accordance with all applicable law.  The Company is not in
        default under or in violation of any provision of its Certificate
        of Incorporation or Bylaws or any other instrument, document or
        agreement setting forth the terms and conditions of any shares of

        shares are issued and outstanding.  Section 3.5 of the Disclosure
        Schedule sets forth a complete and accurate list of (i) all
        holders of options, warrants and other rights to purchase shares
        of the Company's capital stock (collectively, "Options"),
        indicating the type and number of shares subject to each such
        Option, and the exercise price, vesting status and termination
        date of each such Option, and (ii) all holders of any notes or
        other securities that are or may be convertible into shares of
        the Company's capital stock (collectively, "Convertible
        Securities").  All of the issued and outstanding shares of Common
        Stock are, and all shares of the Company's capital stock that may
        be issued upon the exercise of any Options or upon the exercise
        or conversion of any Convertible Securities will be, upon such
        issuance, duly authorized, validly issued, fully paid,
        nonassessable and free of all preemptive rights.  Except as set
        forth in Section 3.5 of the Disclosure Schedule, there are no
        outstanding or authorized shares of capital stock or other
        securities or options, warrants, rights, agreements or
        commitments to which the Company is a party or which are binding
        upon the Company providing for the issuance, disposition or
        acquisition of any of its capital stock or other securities.
        There are no outstanding or authorized stock appreciation,
        phantom stock or similar rights with respect to the Company.
        There are no agreements, voting trusts, proxies, or
        understandings with respect to the voting or registration under
        the Securities Act of 1933 (the "Securities Act"), of any shares
        of any capital stock of the Company to which the Company is
        party, and except as set forth in Section 3.5 of the Disclosure
        Schedule, no shares of the Company's capital stock are currently
        the subject of a registration statement filed under the
        Securities Act.  The Company is not party to any agreements,
        voting trusts, proxies, or understandings with respect to the
        voting or registration under the Securities Act of any shares of
        any capital stock of the Company.  All of the issued and
        outstanding shares of Common Stock and other outstanding
        securities of the Company were issued in compliance with
        applicable federal and state securities laws.  No repurchase of
        capital stock by the Company (i) violated the Company's
        Certificate of Incorporation or Bylaws or any laws, rules or
        regulations applicable to the Company or (ii) caused any breach
        of any agreement to which the Company is or was a party.  The
        Common Stock is listed for trading in the Emerging Company
        Marketplace of the American Stock Exchange, Inc. (the "Exchange")
        and, to the Knowledge of the Sellers, no proceedings to delist
        such Common Stock have been commenced or are contemplated by the
        Exchange.

        Corporation Law; Noncontravention.
        ---------------------------------

                  (a)  The Board of Directors of the Company unanimously
        has, after due consideration of its fiduciary duties and
        immediately prior to the execution of this Agreement, (i)
        determined that this Agreement and the transactions contemplated
        hereby are fair to the Company and the shareholders of the
        Company and (ii) approved this Agreement and the transactions
        contemplated hereby.  The transactions contemplated by this
        Agreement have been approved by all requisite corporate action of
        the Company.  The Board of Directors of the Company has approved
        the Buyer and its affiliates (including Thermo Electron
        Corporation and Thermo Power Corporation) becoming "interested
        stockholders" of the Company, as such term is defined in Section
        203 of the Delaware General Corporation Law and, by reason of
        such approval, the exception to Section 203 contained in Section
        203(a)(1) thereof shall apply to the transactions contemplated
        hereby and to any future "business combinations," as such term is
        defined in Section 203, between the Company and the Buyer and/or
        its affiliates (including Thermo Electron Corporation and its
        subsidiaries).

                  (b)  Neither the execution and delivery of this
        Agreement, nor the consummation of the transactions contemplated
        hereby, require notice to or the approval of the holders of any
        portion of the outstanding shares of Common Stock other than the
        collective approval of the Sellers, which approval has been
        obtained.  Neither the execution and delivery of this Agreement,
        nor the consummation of the transactions contemplated hereby, (a)
        require on the part of the Company or any corporation with
        respect to which the Company, directly or indirectly, has the
        power to vote or direct the voting of sufficient securities to

        For purposes of this Agreement, "Security Interest" means any
        mortgage, pledge, security interest, encumbrance, charge, or

        insurance, social security, retirement, and similar legislation,

        Ordinary Course of Business and not material to the Company and
        its Subsidiaries taken as a whole.   

             Section 3.7.  Subsidiaries.  Section 3.7 of the Disclosure
                           ------------
        Schedule sets forth for each Subsidiary (a) its name and
        jurisdiction of incorporation, (b) the percentage of each class
        of such Subsidiary's outstanding capital stock owned by the
        Company or another Subsidiary and (c) its directors and officers.
        Each Subsidiary is a corporation duly organized, validly existing
        and in good standing under the laws of the jurisdiction of its
        incorporation or organization.  Each Subsidiary is duly qualified
        to conduct business and is in corporate and tax good standing in
        each jurisdiction in which the failure to so qualify would have a
        Material Adverse Effect.  Each Subsidiary has all requisite
        corporate power and authority to carry on the businesses in which
        it is engaged and to own and use the properties owned and used by
        it.  All of the issued and outstanding shares of capital stock of
        each Subsidiary are duly authorized, validly issued, fully paid,
        nonassessable and free of preemptive rights.  All shares of each
        Subsidiary that are held of record or owned beneficially by
        either the Company or any Subsidiary are held or owned free and
        clear of any restrictions on transfer (other than restrictions
        under the Securities Act and state securities laws), claims,
        Security Interests, options, warrants, rights, contracts, calls,
        commitments, equities and demands.  There are no outstanding or
        authorized options, warrants, rights, agreements or commitments
        (contingent or otherwise) to which the Company or any Subsidiary
        is a party or which are binding on any of them providing for the
        issuance, disposition or acquisition of any capital stock of any
        Subsidiary.  There are no outstanding stock appreciation, phantom
        stock or similar rights with respect to any Subsidiary.  There
        are no voting trusts, proxies, or other agreements or
        understandings with respect to the voting of any capital stock of
        any Subsidiary.  The Company does not control directly or
        indirectly or have any direct or indirect equity participation in
        any corporation, partnership, trust, or other business
        association which is not a Subsidiary.

        Subsidiaries have been in existence) (collectively, the
        "Financial Statements").  The Financial Statements have been

        Subsidiaries.

             Section 3.10.  Undisclosed Liabilities.  To the Knowledge of
                            -----------------------
        the Sellers, neither the Company nor any of its Subsidiaries has
        any liability, whether absolute or contingent, liquidated or
        unliquidated, accrued or unaccrued and whether due or to become
        due, except for (a) liabilities shown on the audited balance
        sheet as of December 31, 1996 (the "Most Recent Balance Sheet"),
        (b) liabilities which have arisen since the date of the Most
        Recent Balance Sheet in the Ordinary Course of Business and which
        are similar in nature and amount to the liabilities which arose
        during the comparable period of time in the immediately preceding
        fiscal year and (c) contractual liabilities incurred in the
        Ordinary Course of Business which are not required by GAAP to be
        reflected on a balance sheet.  

             Section 3.11.  Tax Matters.
                            -----------

                  (a)  Each of the Company and the Subsidiaries has filed
        in a timely manner (including permitted extensions) all Tax
        Returns (as defined below) that it was required to file and all
        such Tax Returns were correct and complete in all material
        respects.  All Taxes shown on such Tax Returns have been paid in
        full on a timely basis or have been accrued on the Most Recent
        Balance Sheet, and no other Taxes are owed by the Company with
        respect to items or periods covered by such Returns.  The unpaid
        Taxes of the Company and the Subsidiaries for Tax periods through
        the date of the Most Recent Balance Sheet do not exceed the
        accruals and reserves for Taxes set forth on the Most Recent
        Balance Sheet.  Neither the Company nor any Subsidiary has any
        actual or potential liability for any Tax obligation of any
        taxpayer (including without limitation any affiliated group of
        corporations or other entities that included the Company or any
        Subsidiary during a prior period) other than the Company and the
        Subsidiaries.  All Taxes that the Company or any Subsidiary is or
        was required by law to withhold or collect have been duly
        withheld or collected and, to the extent required, have been paid
        to the proper Governmental Entity.  There are no liens for Taxes
        on the assets of the Company or any Subsidiary other than liens
        for Taxes not yet due and payable.  For purposes of this
        Agreement, "Taxes" means all taxes, charges, fees, levies or
        other similar assessments or liabilities, including without
        limitation income, gross receipts, ad valorem, premium,
        value-added, excise, real property, personal property, sales,
        use, transfer, withholding, employment, payroll and franchise
        taxes imposed by the United States of America or any state, local
        or foreign government, or any agency thereof, or other political
        subdivision of the United States or any such government, and any
        interest, fines, penalties, assessments or additions to tax
        resulting from, attributable to or incurred in connection with
        any tax or any contest or dispute thereof.  For purposes of this
        Agreement, "Tax Returns" means all reports, returns,
        declarations, statements or other information required to be
        supplied to a taxing authority in connection with Taxes.

                  (b)  The Sellers have caused the Company to deliver to
        the Buyer correct and complete copies of all federal income Tax
        Returns, examination reports and statements of deficiencies
        assessed against or agreed to by any of the Company or any
        Subsidiary since December 31, 1993.  The federal income Tax
        Returns of the Company for the year ended December 31, 1995 are
        currently undergoing audit by the Internal Revenue Service.
        Except as set forth in the preceding sentence, the federal income
        Tax Returns of the Company have never been audited by the
        Internal Revenue Service and are closed by the applicable statute
        of limitations for all taxable years through 1993.  No
        examination or audit of any Tax Returns of the Company or any
        Subsidiary by any Governmental Entity is currently in progress
        or, to the Knowledge of the Sellers, threatened or contemplated.
        Neither the Company nor any Subsidiary has waived any statute of
        limitations with respect to Taxes or agreed to an extension of
        time with respect to a Tax assessment or deficiency, which waiver
        or extension is still in effect.  There is no dispute or claim
        concerning any Tax liability of any of the Company and its
        Subsidiaries, either raised or claimed in writing by any
        authority or as to which the Sellers have Knowledge.  No claim
        has ever been made by an authority in a jurisdiction where any of
        the Company and its Subsidiaries does not file Tax Returns that
        it is or may be subject to Tax in that jurisdiction.

                  (c)  Neither the Company nor any Subsidiary is a
        "consenting corporation" within the meaning of Section 341(f) of
        the Internal Revenue Code of 1986 (the "Code") and none of the
        assets of the Company nor the Subsidiaries are subject to an
        election under Section 341(f) of the Code.  None of the Company
        and its Subsidiaries has made any payments or is a party to any
        agreement that under certain circumstances could obligate it to
        make any payments that will not be deductible under Section 280G
        of the Code.  Neither the Company nor any Subsidiary is a party
        to any Tax allocation or sharing agreement.  

                  (d)  Neither the Company nor any Subsidiary is or has
        ever been a member of an "affiliated group" of corporations
        (within the meaning of Section 1504 of the Code), other than a
        group of which only the Company and the Subsidiaries are members.
        Neither the Company nor any Subsidiary has made an election under
        Treasury Reg. Section 1.1502-20(g).  Neither the Company nor any
        Subsidiary is or has been required to make a basis reduction
        pursuant to Treasury Reg. Section 1.1502-20(b) or Treasury Reg.
        Section 1.337(d)-2T(b).

                  (e)  All material elections with respect to Taxes,
        other than those elections reflected in the Tax Returns referred
        to in subsection (b), as of the date hereof are set forth in
        Section 3.11 of the Disclosure Schedule.  None of the assets of
        the Company nor any Subsidiary is property that the Company or
        any Subsidiary is required to treat as being owned by any other
        person pursuant to the "safe harbor lease" provisions of former
        Section 168(f)(8) of the Code.  None of the assets of the Company

                                      -11-

<PAGE>





        nor any Subsidiary directly or indirectly secures any debt the
        interest on which is tax exempt under Section 103(a) of the Code.
        None of the assets of the Company nor any Subsidiary is "tax
        exempt use property" within the meaning of Section 168(h) of the
        Code.  Neither the Company nor any Subsidiary has agreed to make
        or is required to make any adjustment under Section 481 of the
        Code by reason of a change in accounting method or otherwise.
        Neither the Company nor any Subsidiary has participated in an
        international boycott within the meaning of Section 999 of the
        Code. Except as set forth in Section 3.11(e) of the Disclosure
        Schedule, neither the Company nor any Subsidiary has or has had a
        permanent establishment in any foreign country, as defined in any
        applicable treaty or convention between the United States and
        such foreign country.  Neither the Company nor any Subsidiary is
        a party to any joint venture, partnership or other arrangement or
        contract that could be treated as a partnership for federal
        income tax purposes.  

             Section 3.12.  Assets.  Each of the Company and the
                            ------
        Subsidiaries owns or leases all tangible assets necessary for the
        conduct of its businesses as presently conducted and as presently
        proposed to be conducted.  To the Knowledge of the Sellers, each
        such tangible asset is free from material defects, has been
        maintained in accordance with normal industry practice, is in
        good operating condition and repair (subject to normal wear and
        tear) and is suitable for the purposes for which it presently is
        used.  Except as described in Section 3.12 of the Disclosure
        Schedule, no asset of the Company (tangible or intangible) is
        subject to any Security Interest.

             Section 3.13.  Owned Real Property.  Except as set forth in
                            -------------------
        Section 3.13 of the Disclosure Schedule, neither the Company nor
        any Subsidiary owns any real property.  The Company or the
        Subsidiaries have good and marketable title to all such real
        property, and no such real property is subject to any Security
        Interest.

             Section 3.14.  Intangibles.  Set forth in Section 3.14 of
                            -----------
        the Disclosure Schedule is an accurate list and description of
        all patents, trademarks, trade names, service marks, brand names
        and copyrights, and registrations and applications therefor, used
        in the conduct of the business of the Company and the
        Subsidiaries or the use of which is necessary for the business of
        the Company and the Subsidiaries as now being conducted (the
        "Intangibles") and all licenses, sublicenses or other rights or
        obligations entered into or granted by or to the Company and the
        Subsidiaries with respect thereto.  To the Knowledge of the
        Sellers, the Company owns or possesses adequate rights to use,
        free and clear of any obligation of payment, encumbrance, lien or
        claim, all such Intangibles.  No person has made any claim or
        demand upon the Company pertaining to, and no proceeding is
        pending or, to the Knowledge of the Sellers, threatened which
        challenges, the rights of the Company in respect of any
        Intangibles.  To the Knowledge of the Sellers, the Company has

                                      -12-

        not infringed or engaged in the unauthorized use of any patent,
        trademark, trade name, service mark, brand name or copyright, or
        any invention, technology, technical know-how, process, design,
        trade secret or other intellectual property of any third party.  

             Section 3.15.  Real Property Leases.  Section 3.15 of the
                            --------------------
        Disclosure Schedule lists and describes briefly all real property
        leased or subleased to the Company or any Subsidiary and lists
        the term of such lease or sublease, any extension and expansion
        options, and the rent payable thereunder.  The Sellers have
        caused the Company to provide the Buyer with access to correct
        and complete copies of the leases and subleases (as amended to
        date) listed in Section 3.15 of the Disclosure Schedule.  With
        respect to each lease and sublease listed in Section 3.15 of the
        Disclosure Schedule:

        liability as a result of any act or omission by any of such
        entities.  To the Knowledge of the Sellers, there is no previous,
        pending or threatened civil or criminal litigation, written
        notice of violation or noncompliance, formal administrative or
        judicial proceeding, investigation, citation, order, consent
        order, consent decree, inquiry or information request by any
        Governmental Entity, relating to such entities for any violations
        of Environmental Laws.

             Section 3.24.  Legal Compliance.  Each of the Company and
                            ----------------
        the Subsidiaries, and the conduct and operation of their
        respective businesses, are in compliance in all material respects
        with all laws (including rules and regulations thereunder) of any
        federal, state or local government or foreign government of a
        country in which the Company or any of its Subsidiaries does
        business, or any Governmental Entity, which are applicable to the
        Company or such Subsidiary, and none of the Company or any
        Subsidiaries has received any notice from any Governmental Entity
        that it is in violation of, or has violated any such laws
        (including rules and regulations thereunder).

        the Subsidiaries to conduct their respective businesses as
        presently conducted or as proposed to be conducted, except for
        those the absence of which would not have any Material Adverse
        Effect.  Each such Permit is in full force and effect and, to the
        Knowledge of the Sellers, no suspension or cancellation of such
        Permit is threatened and, to the Knowledge of the Sellers, there
        is no basis for believing that such Permit will not be renewable
        upon expiration. Each such Permit will continue in full force and
        effect following the Closing.

             Section 3.26.  Certain Business Relationships with

        and records of the Company and each Subsidiary accurately reflect
        in all material respects the assets, liabilities, business,
        financial condition and results of operations of the Company or

                            -----------
        Subsidiary has any obligation or liability (whether actual,
        accrued, accruing, contingent or otherwise) as guarantor, surety,
        co-signer, endorser, co-maker, indemnitor or otherwise in respect
        of the obligation of any person, corporation, partnership, joint
        venture, association, organization or other entity, except as
        endorser or maker of checks or letters of credit, respectively,
        endorsed or made in the Ordinary Course of Business.

             Section 3.32.  Backlog.  As of March 31, 1997, the Company's
                            -------
        backlog of binding purchase orders was at least $3,074,158.

             Section 3.33.  Government Contracts.  The Company has not
                            --------------------
        been suspended or debarred from bidding on contracts or
        subcontracts with any Governmental Entity and no such suspension
        or debarment has been initiated or, to the Sellers' Knowledge,
        threatened.  The consummation of the transactions contemplated by
        this Agreement will not result in any such suspension or
        debarment.  To the Knowledge of the Sellers, the Company has not
        been audited or investigated and is not now being audited or
        investigated by the U.S. Government Accounting Office, the U.S.
        Department of Defense or any of its agencies, the Defense
        Contract Audit Agency, the U.S. Department of Justice, the

        agencies or instrumentalities of any foreign Governmental Entity,
        or any price contractor with a Governmental Entity nor has any
        such audit or investigation been threatened.  To the Sellers'
        Knowledge, there is no valid basis for (a) the suspension or
        debarment of the Company from bidding on contracts or
        subcontracts with any Governmental Entity or (b) any claim
        pursuant to an audit or investigation by any of the entities
        named in the foregoing sentence.  The Company has no agreements,
        contracts or commitments which require it to obtain or maintain a
        security clearance with any Governmental Entity.

        including demonstration inventory, owned by the Company, for
        manufacturing, assembly, processing, finishing, demonstration and
        sale or resale to others (collectively, "Inventories"), are of a
        quality and quantity usable and salable in the Ordinary Course of
        Business.  Items included in such Inventories are carried on the
        books of the Company at the lower of cost or market and, with
        respect to Inventories existing as of December 31, 1996, are
        reflected on the Most Recent Balance Sheet, net of applicable
        reserves for excess and obsolete items.  Such reserves have been
        determined in accordance with past practices and conform to GAAP.
         
             Section 3.35.  Commission Filings.  The Sellers have caused
                            ------------------
        the Company to provide access to the Buyer to true and complete
        copies of each document (including exhibits, but excluding
        exhibits incorporated by reference) filed by the Company with the
        Securities and Exchange Commission (the "Commission") since
        January 1, 1995 (as such documents have since the time of their
        filing been amended, the "Commission Filings"), which are all
        documents (other than preliminary material) that the Company was
        required to file with the Commission since such date.  As of
        their respective dates, the Commission Filings complied in all
        material respects with the requirements of the Securities Act
        and/or the Exchange Act, as the case may be, and the rules and
        regulations of the Commission thereunder applicable to such
        Commission Filings and none of the Commission Filings when filed
        contained any untrue statement of a material fact or omitted to
        state a material fact required to be stated therein or necessary
        to make the statements therein, at the time in light of the
        circumstances under which they were made, not misleading.  The
        financial statements of the Company included in the Commission
        Filings complied as to form in all material respects with
        applicable accounting requirements and with published rules and
        regulations of the Commission with respect thereto, have been
        prepared in accordance with generally accepted accounting
        principles applied on a consistent basis during the periods
        involved (except as may be indicated therein or in the notes
        thereto or, in the case of the unaudited statements, as permitted
        by the rules of the Commission) and fairly present (subject, in
        the case of the unaudited statements, to normal recurring audit
        adjustments) the consolidated financial position of the Company
        and its consolidated subsidiaries as at the dates thereof and the

        consolidated results of their operations and cash flows for the
        periods then ended.

             Section 3.36.  Disclosure.  No representation or warranty of
                            ----------
        the Company in this Agreement and no statement in the Disclosure
        Schedule omits to state a material fact necessary to make the
        statements herein or therein, in light of the circumstances in
        which they were made, not misleading.


                                    ARTICLE 4

             Section 4.4.  Brokers and Finders for the Buyer.  The Buyer
                          ----------------------------------
        has not employed any broker, agent or finder in connection with
        the transactions contemplated hereby.  


                                    ARTICLE 5

                                CERTAIN COVENANTS

             Section 5.1.  Expenses.  Except as may be otherwise
                           --------
        expressly contemplated hereby, all expenses paid or incurred by
        any party hereto shall be borne by such party.  All sales,
        transfer or similar taxes required to be paid in respect of the
        transfer of the Shares contemplated hereby shall be the
        responsibility of the Sellers.  Notwithstanding the foregoing,
        this Section 5.1 shall not be construed as relieving any party
        from any liability which it may have for any breach of any
        representation or warranty made by it herein or any failure to
        perform any obligation or comply with any covenant imposed on it
        herein.

             Section 5.2.  Further Assurances.  From time to time and at
                           ------------------
        any time after the Closing, and without further expense to the
        requesting party, each party will execute and furnish to the
        requesting party all documents and will do or cause to be done
        all other things that the requesting party may reasonably request
        in order to give full effect to this Agreement and to effectuate
        the intent of the parties. 

             Section 5.3.  Releases.
                           --------

                  (a)  Except as set forth in Section 5.3(b), each Seller
        hereby releases, holds harmless and forever discharges the
        Company and its successors, assigns, agents, servants, employees,
        principals, directors, officers, administrators, stockholders,
        affiliates, subsidiaries and related companies of and from any
        and all actions, causes of action, claims, demands, costs,
        liabilities, losses, expenses and compensation, past, present or
        future, known or unknown, which he ever had, now has or may have
        against any of the foregoing arising from actions, omissions,
        circumstances or conditions that existed on or prior to the
        Closing Date.  This release is binding on the Sellers' heirs,
        assigns and successors in interest.  

                  (b)  Notwithstanding any provision of this Agreement to
        the contrary, including Section 5.3(a) hereof, no Seller hereby
        releases or discharges the Company from any indemnification
        obligations which the Company may have (i) under its Certificate
        of Incorporation or By-Laws with respect to acts or omissions
        occurring prior to the date of this Agreement or (ii) under one
        or more so-called "Indemnification Statements Covering Registered
        Professionals"; provided, however, that this Section 5.3(b) shall
                        --------  -------
        not apply to any indemnification obligation of the Company if and
        to the extent that such obligation arises in connection with any

                                      -25-

<PAGE>





        matter the existence of which would cause any representation or
        warranty set forth in Article 3 to be incorrect or misleading in
        any respect. 

             Section 5.4.  Covenant against Competition.
                           ----------------------------

                  (a)  Each Seller agrees that, while he is employed by
        the Company, and for a period of two years after such Seller's
        voluntary resignation or the termination of the Seller's
        employment by the Company or by the Seller without Cause (as
        defined in Section 5.4(d) below), the Seller will not, directly
        or indirectly:

                       (i)  engage in any business that provides any
             services or products competitive with those offered by the
             Company as of the date of such resignation or termination in
             any jurisdiction within the United States of America in
             which the Company then offer such services or products, or 

                       (ii) without the prior written consent of the
             Company, (i) solicit any person employed by the Company (or
             any of its affiliates) to terminate his employment with the
             Company (or any of such affiliates) or to become an employee
             of the Seller or any person or entity with which the Seller
             may be affiliated, or (ii) hire any such employee except
             employees involuntarily terminated by the Company (or any of
             its affiliates).

                  (b)  The Seller and the Buyer agree that the scope,
        duration and geographic area of the covenant against competition
        set forth in Section 5.4(a) above are reasonable.  In the event
        that any court of competent jurisdiction determines that the
        scope, the duration, the geographic area, or any of them, are
        unreasonable and that such provision is to that extent
        unenforceable, the parties hereto agree that the provision shall
        remain in full force and effect for the greatest scope, for the
        greatest time period and in the greatest area that would not
        render it unenforceable.  The parties intend that such
        noncompetition provision shall be deemed to be a series of
        separate covenants, one for each and every county of each and
        every state in which this provision is intended to be effective.

                  (c)  The Seller agrees that damages are an inadequate
        remedy for any breach of Section 5.4(a) and that the Buyer shall,
        whether or not it is pursuing any potential remedies at law, be
        entitled to equitable relief in the form of preliminary and
        permanent injunctions without bond or other security upon any
        actual or threatened breach thereof.

                  (d)  For purposes of this Agreement only, "Cause" for
        termination of the Seller's employment by the Company shall be
        deemed to exist upon (i) a good faith finding by the Company of
        the failure of the Seller to perform his assigned duties for the
        Company, a material violation of any policy established by the

                                      -26-
PAGE
<PAGE>





        Company (or its affiliates) and made known to the Seller, gross
        insubordination, dishonesty, gross negligence or gross
        misconduct, or (ii) the conviction of the Seller of, or the entry
        of a pleading of guilty or nolo contendere by the Seller to, any
        crime involving moral turpitude or any felony; and "Cause" for
        termination of the Seller's employment by the Seller shall be
        deemed to exist upon the Company's assignment to the Seller of
        duties fundamentally incompatible with the duties of the Seller

             Section 6.1.  Indemnification by the Sellers.  Subject to
                           ------------------------------
        the provisions of Section 6.2, the Buyer upon its demand shall be
        indemnified by the Sellers for all Damages (as defined in Section
        6.5 below) suffered by the Buyer as a result of:

                       (i)  the inaccuracy of any representation or
             warranty made by the Sellers in this Agreement (including
             Article 3) or in any other document executed by the Sellers
             at the Closing; and

                       (ii) any failure by any Seller to perform any
             obligation of such Seller, or to comply with any covenant or
             agreement of such Seller, specified herein (including
             without limitation the covenants set forth in Article 5) or
             in any other document executed by such Seller at the
             Closing.

             The Buyer shall give the Sellers prompt notice of any claim,
        action or proceeding by a third party which is reasonably likely
        to result in a claim for indemnification under this Section 6.1.
        Subject to the provisions of Section 6.2, the Sellers shall have
        the right, at their expense and with counsel selected by the
        Sellers, to defend, contest, protest, settle and otherwise
        control the resolution of any such claim, action or proceeding.
        The Sellers shall keep the Buyer apprised of developments with
        respect to any such claim, action or proceeding, and the Buyer

                                      -27-

        shall have the right to consult with the Sellers, and to
        participate therein, subject to the Sellers' right of control
        thereof, at the Buyer's expense and with counsel selected by the
        Buyer.  If the Sellers shall notify the Buyer that the Sellers
        have elected to assume any such defense, contest or protest, then
        the Sellers shall not be liable to the Buyer hereunder for any
        legal or other expense subsequently incurred by the Buyer in
        connection therewith.

             Section 6.2.  Limitation of Liability of the Sellers.
                           --------------------------------------

                  (a)  Except as set forth below, the right of the Buyer
        to be indemnified pursuant to Section 6.1(i) shall not apply
        until the sum of the Damages suffered by the Buyer on a
        cumulative basis exceeds $50,000, in which case the Buyer shall
        be entitled to recover 100% of the Damages suffered, and not just
        the Damages in excess of $50,000 (subject to the remainder of
        this Section 6.2).  Notwithstanding the foregoing, the Buyer
        shall be entitled to recover the Damages suffered by it with
        respect to claims based solely on representations and warranties
        in Section 3.1, 3.2, 3.4, 3.5 and 3.6(a), irrespective of whether
        such Damages equal or exceed $50,000.  

                  (b)   The right of the Buyer to be indemnified pursuant
        to Section 6.1(i) shall:

                       (i)  apply to claims based solely on
             representations and warranties in Article 3 (other than
             Sections 3.1, 3.2, 3.4, 3.5, 3.6(a) and 3.11) only if
             asserted by the Buyer before the second anniversary of the
             Closing Date;  

                       (ii) apply to claims based solely on
             representations and warranties in Section 3.11 only if
             asserted by the Buyer before any applicable statute of
             limitations for unpaid Taxes shall expire; and

                       (iii)     with respect to claims based solely on
             representations and warranties in Sections 3.1, 3.2, 3.4,
             3.5 and/or 3.6(a), survive the Closing Date indefinitely.

                  (c)  The Sellers shall be jointly and severally liable
        for all Damages claimed by the Buyer pursuant to Section 6.1(i)
        (other than with respect to claims based solely on
        representations and warranties in Sections 3.1, 3.2 and/or 3.3,
        as to which the liability of any Seller for such Seller's
        representations and warranties shall be several and not joint).
        The liability of any Seller for Damages claimed by the Buyer
        pursuant to Section 6.1(ii) shall be several and not joint.  In
        no event shall any Seller be liable for Damages pursuant Section
        6.1 for (i) misrepresentations in Sections 3.1, 3.2 and/or 3.3 by
        any other Seller or (ii) the acts or omissions of any other
        Seller in contravention of Section 6.1(ii).

             Section 6.3.  Indemnification by the Buyer.  Subject to the
                           ----------------------------
        provisions of Section 6.4, the Sellers upon their demand shall be
        indemnified by the Buyer for all Damages suffered by the Sellers
        as a result of

                       (i)  the inaccuracy of any representation or
             warranty made by the Buyer in this Agreement (including
             Article 4) or in any other document executed by the Buyer at
             the Closing; and

                       (ii) any failure by the Buyer to perform any
             obligation of the Buyer, or to comply with any covenant or
             agreement of the Buyer, specified herein (including without
             limitation the covenants set forth in Article 5) or in any
             other document executed by the Buyer at the Closing.

             The party seeking indemnification shall give the Buyer
        prompt notice of any claim, action or proceeding by a third party
        which is reasonably likely to result in a claim for
        indemnification under this Section 6.3.  The Buyer shall have the
        right, at its expense, to defend, contest, protest, settle and
        otherwise control the resolution of any such claim, action or
        proceeding.  The Buyer shall keep the party seeking
        indemnification apprised of developments with respect to any such
        claim, action or proceeding, and such party shall have the right
        to consult with the Buyer, and to participate therein, subject to
        the Buyer's right of control thereof, at such party's expense and
        with counsel selected by such party.  If the Buyer shall notify
        the party seeking indemnification that the Buyer has elected to
        assume any such defense, contest or protest, the Buyer shall not
        be liable to such party hereunder for any legal or other expense
        subsequently incurred by such party in connection therewith.

             Section 6.4.  Limitation of Liability of the Buyer.
                           ------------------------------------

                  (a)  The right of the Sellers to be indemnified
        pursuant to Section 6.3(i) shall not apply until the sum of the
        Damages suffered by the Sellers on a cumulative basis exceeds
        $50,000, in which case the Sellers shall be entitled to recover
        100% of the Damages suffered, and not just the Damages in excess
        of $50,000 (subject to the remainder of this Section 6.4). 

                  (b)   The right of the Sellers to be indemnified
        pursuant to Section 6.3(i) shall:

                       (i)  apply to claims based solely on
             representations and warranties in Article 4 (other than
             Sections 4.1 and 4.2) only if asserted by the Sellers before
             the second anniversary of the Closing Date; and

                       (ii) with respect to claims based solely on
             representations and warranties in Sections 4.1 and 4.2,
             survive the Closing Date indefinitely.

             Section 6.5.  Definition of "Damages."  For the purpose of
                           ----------------------
        this Article 6, the term "Damages" (a) shall be determined and
        computed by reference to the effect of the compensable event on
        the party or parties entitled thereto, (b) shall mean the amount
        finally determined by reason of a settlement or by other final
        resolution of the claim, and (c) shall be deemed to include (i)
        all losses, liabilities, expenses or costs incurred by such party
        or parties, including reasonable attorneys' fees, and (ii)
        interest at a rate per annum equal to that announced from time to
        time by BankBoston as its "base rate" (or the legal rate of
        interest, if lower) from the date on which the amount of Damages
        is determined by reason of a settlement or by another final
        resolution of the claim.  In no event shall any amounts recovered
        from any insurer or other party, or any tax benefit allowable, as
        a result of the facts giving rise to the claim for
        indemnification be deemed to reduce the Damages for which any
        party may be liable hereunder.

        named herein and their respective successors and permitted
        assigns. No party may assign either this Agreement or any of its
        rights, interests, or obligations hereunder without the prior
        written approval of the other parties; provided that the Buyer
        may assign its rights, interests and obligations hereunder to any
        Affiliate of the Buyer.

        words or phrases, or to replace any invalid or unenforceable term
        or provision with a term or provision that is valid and
        enforceable and that comes closest to expressing the intention of

        The Randers Group Incorporated
        570 W. Seminole Road
        Muskegon, Michigan  49444

            Attention:  Thomas R. Eurich, President

        Dear Tom:

            This letter sets forth our proposal with respect to the sale
        to The Randers Group Incorporated ("Randers") of the wholly owned
        engineering and consulting businesses, including the Killam group
        of companies (collectively, the "Business"), of Thermo TerraTech
        Inc. ("Thermo").  If you agree to the terms proposed, please so
        indicate by signing and returning a copy of this letter of intent
        to me.  

            1.    Purchase Price; Consideration.  The purchase price for
                  -----------------------------
        the Business will be mutually determined during the course of our
        negotiations, but, in any event, would not be less than the book
        value of the Business as of the closing of the sale of the
        Business to Randers (the "Closing").  At the Closing, Randers
        will deliver to Thermo the number of newly issued shares (the
        "Shares") of Randers' Common Stock, $.0001 par value per share
        ("Common Stock"), that equals such agreed price divided by
        $0.625. 

            2.    Conditions of the Transaction.  The acquisition of the
                  -----------------------------
        Business by Randers is subject to the following conditions:

                  a.   The completion by Randers of its due diligence
             review of the business and assets of the Business, the scope
             and results of which are satisfactory to Randers.  Such due
             diligence would include, without limitation, contacts with
             customers, employees and suppliers, review of environmental,
             tax, employee benefits and insurance matters, review of the
             lease terms for any and all real property occupied by the
             Business and legal due diligence, including litigation and
             contract review;

                  b.   The negotiation and execution of a mutually
             acceptable Purchase and Sale  Agreement containing customary
             terms and conditions and representations and warranties 
             by Thermo regarding the Business (the "Agreement");  

                  c.   The final approval of the Directors and
             shareholders of Randers and of the      Directors of Thermo;
PAGE
<PAGE>






                  d.   The absence of any development in the status or
             outlook of the Business between the date of this letter of
             intent and the Closing, which in the reasonable judgment of
             Randers is materially adverse to the Business; 

                  e.   The receipt by Randers of an opinion of an
             investment bank to the effect that the transactions
             contemplated hereby are fair to Randers from a financial
             point of view; 

                  f.   The receipt of any required regulatory approvals;

                  g.   The listing of the Shares on the American Stock
             Exchange; and 

                  h.   Continued listing of the Common Stock on the
             American Stock Exchange following the issuance of the
             Shares.

            3.    Obligation to Update.  During the period between the
                  --------------------
        date of acceptance of this letter of intent and the Closing,
        Thermo will advise Randers on a timely basis of all transactions,
        commitments or contingencies that may arise that are of material
        significance to the Business or not in the ordinary course of the
        Business.  Such advice is for information purposes only; Randers
        has no authority of approval or disapproval, and Thermo is
        totally responsible for the consequences of any actions that it
        elects to take during this period.

            4.    Announcements.  The content of any public announcement
                  -------------
        by Randers concerning the subject matter of this letter of intent
        will be subject to the review and approval of Thermo, such review
        to be timely and approval not to be unreasonably withheld.

            5.    Confidentiality.  As some of the information Randers is
                  ---------------
        to receive regarding the Business is proprietary and has not been
        made available to the public, Randers, its affiliates and its
        representatives understand and agree that such information is
        provided solely for the purpose of evaluating the transaction
        contemplated herein and will not disclose any of such information
        to any third party, except as required by applicable law, legal
        process or a stock exchange, without the prior written consent of
        Thermo, provided, however, that any such information may be
        disclosed to Randers' representatives who need to know such
        information for the purpose of evaluating the transaction
        contemplated herein and who agree to keep such information
        confidential.  The obligations of Randers, its affiliates and its
        representative under this paragraph shall not apply to
        information that (i) is or becomes generally available to the
        public other than as a result of a breach of this letter of
        intent by Randers, its affiliates or its representatives, (ii)
        becomes available to Randers from a source other than Thermo or
        its representatives or agents, which source, to Randers'
PAGE
<PAGE>





        knowledge, is not bound by a confidentiality obligation, (iii) is
        known to Randers prior to receiving such information, or (iv) has
        been or subsequently is independently developed by Randers.

            6.    Non-Contravention.  Each party represents and warrants
                  -----------------
        to the other that its execution of this letter of intent does
        not, and the consummation of the transaction contemplated hereby
        will not, cause any breach of any other agreement or other
        obligation, whether written or otherwise, by which such party is
        bound or to which such party's assets are subject. 

            7.    Closing.  The parties intend to use their best efforts
                  -------
        to cause the Closing to occur by August 15, 1997 and, in any
        event, as soon as practicable.

            8.    Binding Effect; Termination.  Notwithstanding anything
                  ---------------------------
        else herein to the contrary, in consideration of the costs that
        the parties will incur in pursuing this transaction, paragraphs
        3, 4 and 5 shall be binding on the parties.  However, if the
        transaction is not consummated by September 15, 1997, (i) this
        letter of intent shall become null and void as of such date,
        except for paragraphs 4 and 5 and (ii) Randers' obligations under
        paragraph 5 shall expire two years after the date this letter of
        intent is executed by the parties.  Nothing contained herein
        shall constitute a legally binding obligation to purchase or sell
        the Business, and, except as expressly provided herein, no party
        shall be legally bound to the other unless and until a definitive
        Agreement shall have been duly authorized, executed and delivered
        by the parties.

            9.    Governing Law.  This letter of intent shall be governed
                  -------------
        exclusively by the laws of the State of Delaware.

            10.   Counterparts.  This letter of intent may be executed in
                  ------------
        one or more counterpart copies, and all of such copies shall
        together constitute a single document.

                     THERMO TERRATECH PURCHASES CONTROLING 
                          INTEREST IN THE RANDERS GROUP

             WALTHAM, Mass., May 13, 1997 - Thermo TerraTech Inc.
        (ASE-TTT) announced today that it has purchased a controling
        interest in The Randers Group Incorporated (ASE-RGI.EC). Thermo
        TerraTech purchased 7,100,000 shares of Randers common stock from
        certain members of Randers' management, and 420,000 shares from
        Thermo Power Corporation (ASE-THP), an affiliate of Thermo
        TerraTech, at a price of $.625 per share. Following these
        transactions, Thermo TerraTech owns approximately 53.3 percent of
        Randers' outstanding common stock. In addition, Thermo Electron
        Corporation (NYSE-TMO), the corporate parent of Thermo TerraTech,
        owns approximately 8.9 percent of Randers common stock.

             Thermo TerraTech also announced that it has entered into a
        letter of intent to transfer its wholly owned engineering and
        consulting businesses, including the Killam group of companies,
        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
        Thermo TerraTech would equal the agreed price divided by $.625.

             The transfer is expected to be completed in approximately 90
        days, and 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 the Randers
        common stock on the American Stock Exchange following the
        transaction.

             The Randers Group, based in Muskegon, Michigan, provides
        design engineering, project management, and construction services
        for industrial clients in the manufacturing, pharmaceutical, and
        chemical-processing industries. The company had revenues of $12.4
        million in 1996.

             "Randers represents another step in our strategy to offer
        high-quality turnkey services to current and prospective clients
        throughout a broader geographic area," said John P. Appleton,
        president and chief executive officer of Thermo TerraTech. "We
        very much look forward to this association."

            Thermo TerraTech Inc. provides environmental services and
        infrastructure planning and design, encompassing a broad range of
        specializations including consulting and design, the remediation
        of soil and fluids, laboratory testing, and metal treating.
        Thermo TerraTech is a public subsidiary of Thermo Electron
        Corporation.
