        Seller shall remain liable for all claims incurred (i.e., service
        provided) prior to the Closing, regardless of when such claims
        are filed ("Incurred But Not Reported") (collectively, the
        "Assumed Liabilities").  Notwithstanding anything to the contrary
        contained in this Agreement or in any agreement, document,
        certificate or instrument being delivered pursuant to this
        Agreement (collectively, the "Transaction Documents"), Buyer's

        that the existence of such liabilities or obligations is not
        contrary to any covenant, representation or warranty of Seller
        under this Agreement.

        GDC incinerators, and the Burns and Roe (CJ 4447) or any claims
        which arise from exposure to asbestos from products manufactured

        taxable period that begins before but has not ended on the
        Closing Date (all such liabilities and obligations not being
        assumed by Buyer, "Excluded Liabilities").


                                   ARTICLE II

                       CONSIDERATION AND MANNER OF PAYMENT

             2.1  Purchase Price.

                  (a)  Subject to the provisions of Section 2.2 below,
        the aggregate purchase price to be paid by Buyer to Seller for
        the Business, the Assets and Seller's agreement to abide by the
        Restrictive Covenants (as defined below) is (i) $13,000,000,
        minus Excluded Receivables, minus the 90 Day Receivables (as
        defined below), payable by Buyer at the Closing (net of the
        Holdback Amount as defined in Section 2.1(b)) by wire transfer of
        immediately available funds, plus (ii) $2,218,000, payable by
        Buyer at the Closing by delivery of a promissory note in the form
        of Exhibit 2.1(a)(ii) hereto (the "Note"), plus
        (iii) $663,117.82, payable by Buyer at the Closing by delivery of
                                        6PAGE

        a promissory note in the form of Exhibit 2.1(a)(iii) hereto (the
        "90 Day Receivables Note") which amount shall equal 90% of the
        aggregate amount of those accounts receivable of Seller, set
        forth on Schedule 2.1 (the "90 Day Receivables"), plus (iv)
        Buyer's assumption of the Assumed Liabilities (the "Purchase
        Price").  The parties agree that all cash receipts related to
        assumed receivables or other activities (expressly excluding
        Excluded Receivables and Retained Receivables) after September
        27, 1997 are for the benefit of Buyer and within six days of the
        date hereof, by mutual agreement of the parties, such cash
        receipts between September 27, 1997 and the Closing Date, less
        liabilities assumed by Buyer pursuant to Section 1.4(a)(ii) but
        paid by Seller and any receivables that are Excluded Receivables
        or Retained Receivables will be remitted by wire transfer from
        Seller to Buyer.  Any checks issued by Seller after September 27,
        1997 for items that relate to Excluded Assets or Excluded
        Liabilities and items that were not accrued for on the Estimated
        Net Book Value will remain the responsibility of Seller.

                  (b)  The parties agree that Buyer shall holdback
        $520,000 of the Purchase Price (the "Holdback Amount") pursuant
        to Section 2.2 hereof.

                  (c)  Prior to the Closing, Seller delivered to Buyer a
        statement of the Company's net book value (the "Net Book Value")
        of the Assets and the Assumed Liabilities based on the Company's
        unaudited balance sheet dated as of September 27, 1997 (the
        "Estimated Net Book Value"), calculated in accordance with GAAP
        consistently applied by Seller and set forth on Exhibit 2.1(c).
        The Purchase Price is based on the assumption that the Estimated
        Net Book Value is equal to $13,218,000 (the "Preliminary Net Book
        Value", as such amount was calculated on March 29, 1997 and as
        set forth on Exhibit 2.1(c)).  Because the parties have
        determined that the Estimated Net Book Value exceeds the
        Preliminary Net Book Value by $2,007,003.04, the Purchase Price
        shall be paid in accordance with this Section 2.1, and, in
        addition, Seller shall retain all right, title and interest in
        and to the Retained Receivables having an aggregate value of
        $2,007,003.04, which amount shall be equal to the difference
        between the Estimated Net Book Value and the Preliminary Net Book
        Value.

             2.2  Post-Closing Adjustment.  In addition, the Purchase
        Price shall be subject to final adjustment as follows:

                  (a)  Purchase Price Adjustment Schedule.  As soon as
        practicable following the Closing Date, but not later than 30
        days after the Closing Date, Buyer shall deliver to Seller a
        schedule (the "Final Purchase Price Adjustment Schedule") setting
        forth Buyer's final determination of the Purchase Price (the
        "Final Purchase Price"), based upon a net book value calculation
        as of September 27, 1997 (the "Final Net Book Value"), which
        shall be calculated in accordance with GAAP consistently applied
        by Seller.
                                        7PAGE

                  (b)  Protest Notice.  Within 15 days of Buyer's
        delivery of the Final Purchase Price Adjustment Schedule, Seller
        may deliver written notice (the "Protest Notice") to Buyer of any
        objections, and the basis therefor, that Seller may have to the
        Final Purchase Price or the Final Net Book Value.  The failure of
        Seller to deliver such written notice within the prescribed time
        period will constitute Seller's acceptance of the Final Purchase
        Price and the Final Net Book Value, as determined by Buyer.

                  (c)  Resolution of Buyer's Protest.  If Buyer and
        Seller are unable to resolve any disagreement between them within
        10 days following Buyer's receipt of the Protest Notice, then the
        items in dispute will be referred to a nationally recognized
        independent accounting firm (other than Arthur Anderson, LLP or
        Price Waterhouse LLP) (the "Accountants") for final
        determination.  If the Accountants determine that the Buyer's
        calculation of the items in dispute is correct, the Seller shall
        be liable for all of the fees and expenses of the Accountants of
        the items in dispute.  If the Accountants determine that the
        Seller's calculation of the items in dispute is correct, the
        Buyer shall be liable for all of the fees and expenses of the
        Accountants.  If the Accountants' final determination is between
        the Buyer's calculation and Seller's calculation of the items in
        dispute, the Accountants' fees and expenses will be allocated
        between the Buyer and Seller by applying a pro rata, straight
        line allocation based on the difference between both (i) each of
        the Buyer's and Seller's calculation of the items in dispute on
        the one hand, and (ii) the Accountants' final determination and
        each of Buyer's and Seller's calculation of the items in dispute
        on the other hand.  For example, if the Buyer's calculation of
        the items in dispute is $100,000, the Seller's calculation of the
        items in dispute is $50,000 (thereby making the disputed
        difference $50,000), and the Accountants' final determination is
        $90,000, the Seller shall pay for 80% ($40,000 indicating the
        difference between the Seller's and Accountants' determination
        divided by $50,000 indicating the difference between the Buyer's
        and Seller's calculation) and the Buyer shall pay for 20% of the
        fees and expenses of the Accountants.

                  (d)  Payment of Adjustment.  Within 10 days following
        the final determination of the Final Purchase Price and Final Net
        Book Value pursuant to this Section 2.2:

                           (i)   if the Final Net Book Value is less than
                      the Estimated Net Book Value, Buyer will be
                      entitled to receive, an amount equal to the
                      deficiency, up to the Holdback Amount net of any
                      amount for which Seller is liable pursuant to
                      Section 2.2(c) which deduction shall not exceed
                      $10,000.00; provided that any remaining balance of
                      the Holdback Amount shall be distributed to
                      Seller;

                                        8PAGE

                           (ii)  if the Final Net Book Value is equal to
                      the Estimated Net Book Value, the Buyer will
                      distribute to Seller the entire Holdback Amount;
                      and

                           (iii) if the Final Net Book Value is greater
                      than the Estimated Net Book Value, the Buyer will
                      distribute the entire Holdback Amount to Seller
                      and Buyer will pay Seller the excess in an amount
                      up to, but in no event to exceed, $520,000 net of
                      any amount for which Buyer is liable pursuant to
                      Section 2.2(c), which deduction shall not exceed
                      $10,000.00.

                  (e)  Agreed Upon Amounts.  Buyer and Seller agree that
        both the Estimated Net Book Value and the Final Net Book Value
        will (i) reflect or include reserves which are equal to, or
        greater than, the reserves set forth in the Preliminary Net Book
        Value, (ii) take into account any credits which Buyer and Seller
        reasonably agree to be due to customers of Seller for products
        shipped prior to the Closing, (iii) exclude capitalized research
        and development costs in the amount of $287,748.00, (iv) exclude
        non-depreciated fixed assets related to relocation costs in the
        amount of $46,517.14 and (v) employee advances not expensed in
        the amount of $46,567.82.  Seller has reserved $200,000 on the
        Estimated Net Book Value, representing 50% of $400,000 of slow
        moving or obsolete inventory, for which no further purchase price
        adjustment will be made.  If there is any slow moving or obsolete
        inventory in excess of $400,000 but less than $500,000, an
        adjustment to the Final Net Book Value will be made to the extent
        of 50% of such amount; for any amounts in excess of $500,000 a
        100% adjustment will be made subject to Section 2.2(f) below.

                  (f)  Limitation of Liability; Exclusive Remedy.
        Notwithstanding anything to the contrary in this Agreement or any
        Transaction Document, in no event shall any adjustment to the
        Purchase Price in favor of Buyer exceed the aggregate of the
        Holdback Amount and in no event shall any adjustment to the
        Purchase Price in favor of Seller exceed $520,000.  The
        provisions of this Section 2.2 shall be the exclusive remedy by
        which the parties may cause adjustments to the Purchase Price,
        and neither party shall have any recourse to any other provision
        of this Agreement or any Transaction Document to adjust the
        Purchase Price to any extent not provided for in this Section
        2.2; provided, however, that the foregoing shall not prevent (i)
        the Buyer from asserting any claims for indemnification under
        Article 7 hereof, to the extent that Buyer has not submitted a
        claim for adjustment to the Purchase Price pursuant to this
        Section 2.2 and did not, in good faith, know or believe, prior to
        the time the Buyer delivers its Final Purchase Price Adjustment
        Schedule, that such claims for indemnification existed or (ii)
        the Seller from asserting any claims for indemnification under
        Article 7 hereof.

                                        9PAGE

             2.3. Noncompetition Payments.  Buyer and the Seller hereby
        agree that $50,000 of the Purchase Price shall be in
        consideration for Seller's agreement to abide by the Restrictive
        Covenants (as defined herein).

             2.4. Purchase Price Allocation.  The Buyer and Seller shall
        attempt to allocate the cash portion of the Purchase Price among
        the Assets by mutual written agreement within one hundred and
        eighty (180) days after the Closing.  Seller and Buyer agree to
        make all appropriate tax filings on a basis consistent with the
        agreed allocation, if any.


                                   ARTICLE III

                     SELLER'S REPRESENTATIONS AND WARRANTIES

             As an inducement to Buyer to enter into and perform its
        obligations under this Agreement, Seller represents and warrants
        to and with Buyer, on the date hereof, as follows:

             3.1  Organization and Good Standing.  Seller is a
        corporation duly organized, validly existing and in good standing
        under the laws of the State of Delaware.  Seller has full
        corporate power and authority to execute and deliver the
        Transaction Documents to which it is a party, to perform its
        obligations hereunder and thereunder and to consummate the
        transactions contemplated hereby and thereby.  Seller is duly
        licensed and qualified to do business as a foreign corporation
        and is in good standing in each jurisdiction in which the
        location of the Assets or the character of the operations of the
        Business requires such license or qualification, except for those
        jurisdictions where the failure to be so qualified or in good
        standing would not individually or in the aggregate have a
        material adverse effect on the Assets or the operations of the
        Business.

             3.2  Corporate Authorization.  The execution and delivery of
        this Agreement and the other Transaction Documents, and the
        performance by Seller of its obligations hereunder and
        thereunder, have been duly authorized by all necessary corporate
        action.  This Agreement and the other Transaction Documents to
        which Seller is a party constitute the legal, valid and binding
        obligations of Seller, enforceable against Seller in accordance
        with their respective terms, subject to applicable bankruptcy,
        insolvency, reorganization, receivership, moratorium and other
        similar laws affecting the rights and remedies of creditors
        generally, and to general principles of equity, whether applied
        by a court of law or equity.

             3.3  No Violation.  The execution, delivery and performance
        by Seller of the Transaction Documents to which it is a party and
        the consummation of the transactions contemplated herein and
        therein will not:
                                       10PAGE

                  (a)  except as set forth in Schedule 3.3, result in the
        breach of any of the terms or conditions of, or constitute a
        default under, or in any manner release any party thereto from
        any obligation under, any mortgage, note, bond, indenture,
        contract, agreement, license or other instrument or obligation of
        any kind or nature by which Seller, the Business or any of the
        Assets may be bound.

                  (b)  violate any order, writ, injunction, regulation,
        statute or decree of any court, administrative agency, or
        governmental body specifically applicable to Seller, the Assets
        or the Business; or

                  (c)  violate any provision of the Articles of
        Incorporation, Bylaws or Charter Documents of Seller.

             3.4  No Consent Required.  Except as set forth on Schedule
        3.4, no consent, approval, order or authorization of, or
        declaration, filing or registration with, any person, entity or
        governmental authority is required to be made or obtained by
        Seller in connection with the authorization, execution, delivery
        or performance of this Agreement, the other Transaction Documents
        or the transactions contemplated hereby and thereby.

             3.5  Financial Statements.  Schedule 3.5 contains the
        following financial statements of the Holcroft Division of Seller
        (the "Financial Statements"):

                       (i)     The unaudited financial statements for
                  fiscal years ended March 28, 1992 through March 29,
                  1997; and

                       (ii)    The unaudited interim financial
                  statements for the six months ended September 27,
                  1997.

             Each of the Financial Statements is complete and correct in
        all material respects, is consistent with the books and records
        of the Holcroft Division and fairly presents the Holcroft
        Division's financial condition, assets and liabilities as of its
        respective dates and the results of operations and cash flows for
        the periods related thereto.  The Financial Statements were
        prepared in accordance with GAAP consistently applied by Seller
        (except for footnote disclosure). 

             3.6  Absence of Undisclosed Liabilities.  As of the Closin

        Date, to Seller's knowledge, Seller will not have any material
        debts, liabilities or obligations that can reasonably be expected
        to have a material adverse effect on the Business or the Assets
        (whether accrued, absolute, contingent, direct, indirect,
        perfected, inchoate, unliquidated or otherwise and whether due or
        to become due) arising out of transactions entered into on or
        prior to the Closing Date, or any transaction, series of
                                       11PAGE

        transactions, action or inaction occurring on or prior to the
        Closing Date, or any state of facts or condition existing on or
        prior to the Closing Date (regardless of when such liability or
        obligation is asserted), including, but not limited to,
        liabilities or obligations on account of Taxes or governmental
        charges or penalties, interest or fines thereon or in respect
        thereof, except (a) as and to the extent clearly and accurately
        reflected and accrued for or reserved against in the Estimated
        Net Book Value, (b) for liabilities specifically delineated on
        Schedule 3.6, (c) for liabilities expressly disclosed on any
        Schedule hereto and (d) for liabilities incurred in the ordinary
        course of business since September 27, 1997.

             3.7  Assets.

                  (a)  Title.  Except for the Property which is the
        subject of the Sublease and except as set forth on Schedule 3.7,
        Seller owns all of the Assets and the Assets constitute all of
        the property and assets which are considered part of the Business
        and all of the assets deemed necessary by Seller to conduct the
        Business as presently conducted.  Seller has the right to convey,
        and upon the consummation of the transactions contemplated by
        this Agreement Seller will have conveyed and Buyer will be vested
        with, good and marketable title and interest in and to the
        Assets, free and clear of all Liens except as set forth on
        Schedule 3.7.

                  (b)  Inventories.  Except as set forth on Schedule 3.7,
        the inventories of Seller related to the Business are in good and
        saleable condition, subject to the reserves used in determining
        the Estimated Net Book Value, which reserves are sufficient to
        cover all inventory which is not good and saleable in the
        ordinary course of business, obsolete inventory, or materials
        below standard quality.  The inventories constituting raw
        materials are of a type that are readily useable in connection
        with the finished goods offered for sale by the Seller.

                  (c)  Accounts Receivable.  All of the Seller's accounts
        receivable arising out of, or related to, the Business have
        arisen in bona fide arm's-length transactions in the ordinary
        course of business.  Except to the extent of any reserves for bad
        debts set forth in the determination of the Estimated Net Book
        Value, which is sufficient to cover all bad debts, all such
        receivables are valid and binding obligations of the account
        debtors without any counterclaims, set-offs or other defenses
        thereto and are collectible in the ordinary course of business.

                  (d)  Condition and Location.  Except as set forth in
        Schedule 3.7, on the Closing Date, the tangible, personal
        property comprising the Assets (other than inventory) is in good
        operating condition and is useable in the ordinary course of
        business.  All of such tangible assets which are part of the
        Assets are in good condition and repair, ordinary wear and tear
        excepted.  None of such Assets requires any repair or
                                       12PAGE

        replacement, except for maintenance in the ordinary course of
        business.  Except as set forth on Schedule 3.7, none of the
        tangible personal property of the Seller used in the Business is
        held under any lease, security agreement, conditional sales
        contract or other title retention or security arrangement, or is
        located other than at the Property.

                  (e)  Unbilled Work-in-Progress.  The current status of
        the Company's contracts with respect to unbilled work-in-progress
        is accurately reflected in the Estimated Net Book Value.

             3.8  Compliance with Laws; Permits.  Seller, with respect to
        its Holcroft Division, is not in material violation of any law,
        regulation or requirement applicable to it, the Assets, any
        Employee Benefit Plans or the operation of the Business, nor has
        the Seller received written notice of any such violation, that
        individually or in the aggregate would have a material adverse
        affect on the Assets or the operation of the Business.  Seller
        holds all of the material Permits necessary or desirable for the
        current use, occupancy or operation of the Assets, except where
        failure to obtain such Permits would not individually, or in the
        aggregate, have a material adverse affect on the Assets or the
        Business, and all of which are set forth on Schedule 3.8.  Seller
        is in compliance with each of such Permits, all of which are in
        full force and effect.  Except as set forth in Schedule 3.8, each
        of the Permits is freely transferable and will constitute part of
        the Assets.  Seller further represents and warrants that all of
        its employees at the Holcroft Division have proper citizenship
        and/or work authorization documents.

             3.9  Property.  The Property constitutes all real property
        used and occupied by Seller in connection with the Business.  The
        Property is subject to a lease between TMO and Landlord (the
        "Lease"), and to a sublease between TMO and Seller (the "TMO
        Sublease").  Each of the Lease and the TMO Sublease is in full
        force and effect and no default by TMO or Seller has occurred
        under the Lease or the TMO Sublease.

                  (a)  Easements.  Seller has all easements and rights
        necessary to conduct the Business on the Property as presently
        conducted;

                  (b)  Condemnation.  No portion of the Property is
        subject to any pending condemnation proceeding or proceeding by
        any public or quasi-public authority materially adverse to the
        Property and, to the knowledge of Seller, there is no threatened
        condemnation or proceeding with respect to the Property;

                  (c)  Condition.  To the knowledge of Seller, the
        buildings and fixtures located on the Property including, without
        limitation, heating, ventilation, mechanical, electrical, sewer,
        sprinkler and air conditioning systems, roof, foundation and
        floors (the "Building and Fixtures"), have been properly
        maintained and are in operating condition.  To the knowledge of
                                       13PAGE

        Seller, the Building and Fixtures are in good operating
        condition, are substantially fit for the purposes for which they
        are being utilized, and are not in need of any material repair or
        replacement;

                  (d)  Zoning.  To the knowledge of Seller, except as
        disclosed in Schedule 3.9(d), the Property (or the use, occupancy
        and ownership thereof) does not violate any zoning, subdivision,
        health, safety, handicapped persons, landmark preservation,
        wetlands preservation, building, land use or other ordinances,
        laws, codes or regulations or any covenants, restrictions or
        other documents of record (including the Americans with
        Disabilities Act), nor, has any such violation been claimed by,
        nor has any notice of any violation been issued to Seller by any
        governmental, public or quasi-public authority;

                  (e)  Subleases.  Except as set forth on Schedule
        3.9(e), there are no leases, subleases, licenses, concessions or
        other agreements, written or oral, granting to any party or
        parties, other than Buyer, the right of use or occupancy of any
        portion of the Property; and

                  (f)  Utilities.  The Property is supplied with
        utilities and other services necessary for the operation of the
        Business as presently conducted, and all such services are
        adequate to conduct that portion of the Business presently
        conducted at the Property and are, to the knowledge of Seller, in
        accordance with all laws, ordinances, rules and regulations
        applicable to Seller or the Property, except where failure to
        comply with such laws, ordinances, rules and regulations would
        not have individually or in the aggregate a material adverse
        effect on the Assets or in the operations of the Business as
        presently conducted.

             3.10 Leases.  All leases of the personal property leased by
        Seller in connection with the Business, including all such leases
        with related parties or affiliates, are listed on Schedule 3.10,
        correct and complete copies of which previously have been
        furnished to Buyer.  All leases with affiliates and related
        parties, if any, carry terms and conditions no less favorable nor
        more favorable in all material respects to the Seller than those
        which could have obtained in arm's-length transactions with
        unrelated third parties.  Seller enjoys peaceful and undisturbed
        possession under all such leases, and all of such leases are
        valid and in full force and effect and neither Seller, nor to the
        knowledge of Seller, any other party thereto, is in default under
        any of such leases and no event has occurred which with the
        giving of notice or the passage of time or both could constitute
        a default under any of such leases.

             3.11 Contracts.  Schedule 3.11 is a correct and complete
        list of every material contract, agreement, purchase order,
        relationship or commitment, written or oral, arising out of or
        related to the Business, to which Seller is a party or by which
                                       14PAGE

        it or any of the Assets are bound (the "Material Contracts"),
        correct and complete copies of which previously have been
        provided to the Buyer.  Except as set forth on Schedule 3.11,
        each of the Material Contracts may be assigned to Buyer without
        the consent, approval, novation or waiver of any third party.
        Seller is not in default, and no event has occurred which with
        the giving of notice or the passage of time or both would
        constitute a default by Seller, under any Material Contract.  To
        the knowledge of Seller, no other party to the Material
        Contracts, is in default under a Material Contract and no event
        has occurred which with the giving of notice or the passage of
        time or both could constitute a default under any of such
        Material Contracts.  Since March 29, 1997, there has been no
        cancellation or threatened termination of a Material Contract.
        For purposes of this Agreement the term "Material Contracts"
        shall include all contracts which (i) require aggregate payments
        to or by Seller in excess of $20,000 or (ii) have a term or
        effective period longer than 1 (one) year in duration.

             3.12 Intellectual Property.  Schedule 3.12 contains a
        complete and correct list of all Proprietary Rights owned by
        Seller which are used in connection with the Business, including,
        without limitation, filed and pending patent applications and
        applications for the registration of other Proprietary Rights
        owned or filed by Seller.  Schedule 3.12 also contains a complete
        and correct list of all licenses and other rights granted by
        Seller to any third party with respect to the Proprietary Rights
        and licenses and other rights granted by any third party to
        Seller in connection with the Business.  With respect to the
        Proprietary Rights: (a) Seller owns and possesses all right,
        title and interest in and to, or has a valid license to use, all
        of the Proprietary Rights necessary for the operation of the
        Business as presently conducted and none of such Proprietary

                            COVENANTS AND AGREEMENTS

             5.1. Further Actions.

                  (a)  Each of the parties hereto agrees to use all
        reasonable efforts to take, or cause to be taken, all action and
        to do, or cause to be done, all reasonable things necessary,
        proper or advisable to consummate the transactions contemplated
        by this Agreement and the Transaction Documents, including using
        all reasonable efforts to:  (i) give all notices and effect all
        necessary registrations and filings; and (ii) defend any lawsuits
                                       23PAGE

        or other legal proceedings, whether judicial or administrative
        and whether brought derivatively or on behalf of third parties
        (including governmental agencies or officials), challenging this
        Agreement, the Transaction Documents, or the consummation of the
        transactions contemplated hereby and thereby.  If at any time
        after the Closing any further action is deemed necessary or
        desirable by either party to carry out the purposes of this
        Agreement or the Transaction Documents, the proper officers
        and/or directors of Buyer and the Seller shall use all reasonable
        efforts to take such action.

                  (b)  To the extent that a third party consent or waiver
        is necessary to assign to Buyer any claim, contract, agreement,
        license, lease, commitment, purchase order or sales order that is
        being transferred to Buyer pursuant to Section 1.1 hereof (a
        "Contract Requiring Consent") and such consent or waiver is not
        obtained prior to the Closing Date, Seller shall, commencing on
        the Closing Date and continuing for the term of such Contract
        Requiring Consent, use its (i) best efforts to provide to Buyer
        the benefits of such Contract Requiring Consent and (ii)
        reasonable efforts consistent with past practices, to enforce for
        the benefit of Buyer, or allow Buyer to enforce (and, solely for
        such purpose, Seller hereby constitutes and appoints Buyer as its
        true and lawful attorney-in-fact until revoked in a writing
        delivered by Seller to Buyer), with Buyer assuming Seller's
        obligations thereunder, any and all rights of Seller under such
        Contract Requiring Consent against the issuer thereof or the
        other party or parties thereto.  In addition, Seller will pay
        promptly to Buyer when received all monies received by Seller
        after September 27, 1997 under any Contract Requiring Consent to
        the extent  that Buyer would be entitled thereto pursuant to this
        Agreement.  Seller shall have no other duties or obligations with
        respect to any such Contract Requiring Consent, and the failure
        or inability to obtain any necessary consent or waiver with
        respect thereto shall in no event (i) be a breach of this
        Agreement so long as Seller has carried out its obligations under
        this Section 5.1(b) or (ii) limit, or in any way affect, Buyer's
        assumption of the liabilities that arise under such Contract
        Requiring Consent pursuant to Section 1.4(a) hereof.

             5.2. Noncompetition and Nondisclosure.

                  (a)  Noncompetition.  In furtherance of the sale of the
        Assets and the Business to Buyer hereunder by virtue of the
        transactions contemplated hereby and to more effectively protect
        the value of the Assets and the Business so sold, Seller
        covenants and agrees that, for a period ending on the fifth
        anniversary of the Closing Date (the "Term"), neither Seller nor
        any of its respective officers, directors or affiliates, will
        (a) engage, directly or indirectly, in the Business anywhere
        where Seller sold prior to the Closing or the Buyer sells, during
        the Term, products and/or services relating to the Business;
        provided, however, that Seller's Metallurgical Services Group may
        (i) continue to engage in the heat treating of parts and
                                       24PAGE

        (ii) sell for its account that certain furnace having contract
        job number 4664 to Wilson Tools; (b) solicit any party who is or
        was a customer or supplier of the Holcroft Division, or who
        becomes a customer or supplier of Buyer at any time during the
        Term, for the purpose of engaging in, or assisting any person or
        entity in engaging in, any business which competes directly or
        indirectly with the Business, other than in connection with
        Seller's Metallurgical Services Group's heat treating of parts;
        or (c) solicit for employment any employee of Buyer (including
        those of Seller's employees hired by Buyer).  Notwithstanding the
        foregoing, nothing contained in this Section 5.2 shall prohibit
        Seller, or its respective officers, directors,  affiliates from
        owning not more than five percent (5%) of any class of stock
        listed on a national securities exchange or traded in the
        over-the-counter market or continuing to own any interest in any
        noncompetitive business owned by Seller or such officer, director
        or affiliate as of the Closing Date.

                  (b)  Confidentiality.  After the Closing, Seller and
        its directors shall, and Seller shall cause its respective
        officers, employees, agents and affiliates to, maintain the
        confidentiality of all information, documents and materials
        relating to the Business, the Assets or the transactions
        contemplated by this Agreement which remain in their possession,
        except to the extent disclosure of any such information is
        required by law or authorized by Buyer or reasonably occurs in
        connection with disputes over the terms of this Agreement.  In
        the event that Seller reasonably believes after consultation with
        counsel that it is required by law to disclose any confidential
        information described in this Section 5.2(b), it will (a) provide
        Buyer with prompt notice before such disclosure in order that
        Buyer may attempt to obtain a protective order or other assurance
        that confidential treatment will be accorded to confidential
        information, and (b) cooperate with Buyer in attempting to obtain
        such order or assurance.  The provisions of this Section 5.2(b)
        shall not apply to any information, documents or materials which
        are in the public domain or shall come into the public domain,
        other than by reason of default by Seller or its affiliates of
        this Agreement.

                  (c)  Rights and Remedies Upon Breach.  Upon a breach,
        or threatened breach, of any of the provisions of Sections 5.2(a)
        or 5.2(b) (the "Restrictive Covenants"), Buyer shall have the
        right and remedy to have the Restrictive Covenants specifically
        enforced by any court of competent jurisdiction, without the
        necessity of posting a bond, it being agreed that any breach or
        threatened breach of the Restrictive Covenants would cause
        irreparable injury to Buyer and that money damages would not
        provide an adequate remedy to Buyer.  Buyer shall also have any
        other rights and remedies available to Buyer under law or in
        equity.

                  (d)  Severability of Covenants.  Seller acknowledges
        and agrees that the Restrictive Covenants are reasonable and
                                       25PAGE

        valid in geographical and temporal scope and in all other
        respects.  If any court determines that any of the Restrictive
        Covenants, or any part thereof, is invalid or unenforceable, the
        remainder of the Restrictive Covenants shall not thereby be
        affected and shall be given full effect, without regard to the
        invalid portions.

                  (e)  Duration and Scope of Covenant.  If any court
        determines that any of the Restrictive Covenants, or any part
        thereof, is unenforceable because of the duration or geographic
        scope of such provision, such court shall have the power to
        reduce the duration or scope of such provision to the maximum
        extent allowed, as the case may be, and, in its reduced form,
        such provision shall then be enforceable.

             5.3. Holcroft Name. Seller acknowledges and agrees that all
        of its rights in and to, and ownership of, the name "Holcroft,"
        or any variations thereof shall be transferred hereunder to
        Buyer. From and after the Closing, the Seller shall be prohibited
        from using the Holcroft name or a name similar thereto.

             5.4. Offer of Employment.  Buyer shall offer employment with
        Buyer to each employee of the Holcroft Division (collectively,
        the "Employees") after the Closing (i) at the same base salary;
        (ii) with a total benefits package which shall be comparable with
        those benefits set forth on Schedule 5.4, except for the Seller's
        employee stock purchase plan and the Seller's employee stock
        option plan; and (iii) with comparable job responsibilities and
        title as such employee had immediately prior to the Closing.
        Buyer will give such employees credit for service with the
        Holcroft Division with respect to (a) any of Buyer's benefit
        plans which have vesting or length of service requirements,
        except Buyer's equity appreciation rights program and (b) all
        severance payments, if any, made in connection with a termination
        following the Closing Date.  Buyer shall comply with all terms of
        the Union Contract, including, without limitation, seniority and
        lay-off requirements.  Buyer shall be responsible for, and hold
        Seller harmless against, any payments that arise after Closing or
        are properly accrued for on the Estimated Net Book Value
        (including, without limitation, salaries, commissions, bonuses,
        vacation pay, sick pay, severance pay, employee benefits and
        unemployment taxes) that may be due by reason of termination of
        employment of Employees at any time on or after the Closing Date.
        Seller shall be responsible for any employment-related claims
        filed by any Employees which were (i) filed prior to the Closing
        Date or (ii) filed after the Closing Date but which arose from
        facts and circumstances which existed prior to the Closing Date.

             5.5. WARN Act.  During the period commencing on the Closing
        Date and ending ninety days after the Closing Date, Buyer shall
        not take any action that independently, or in connection with any
        action taken by Seller prior to the Closing Date, could be
        construed as a "plant closing" or "mass layoff" within the
        meaning of the WARN Act or the regulations enacted thereunder.
                                       26PAGE

        If Buyer takes any such action during such 90-day period, Buyer
        shall be solely responsible for providing any notice required by
        the WARN Act and for making payments, if any, which may be
        required under the WARN Act and for any other liabilities related
        to its failure to provide appropriate notice.

             5.6. Letters of Credit.  Buyer agrees that it will not take
        any action to extend the terms of the letters of credit set forth
        on Schedule 5.6 (the "Letters of Credit").

        arising out of or in connection with any treatment, storage, or
        disposal of any Hazardous Materials, or the arranging therefor by
        Seller and any discharge or release of any Hazardous Material
        onto, at or under the Property or any other real property
        previously owned or operated by Seller and used in connection
        with the Business, whether or not such acts, omissions,
        circumstances or conditions constituted a violation of or
        obligation under Environmental and Safety Requirements as then in
        effect;

                  (c)  any liability or obligation of Seller or any

                                       30PAGE

                  (e)  up to an aggregate of $85,000 of any Losses
        relating to, resulting from or arising out of any obligations of
        Buyer under the Severance Agreements; or

                  (f)  any action taken by Thermo, directly or
        indirectly, which, if taken by Seller, would result in a
        violation or breach of the representations and warranties set
        forth in Section 5.2 hereof, except for sales by Thermo

        technology.

             Seller agrees to promptly pay to or reimburse a Buyer
        Indemnified Party for all Losses incurred by such Buyer
        Indemnified Party.

             7.2  Indemnification by Buyer.  From and after the Closing,
        Buyer agrees to indemnify, defend and save Seller and its
        affiliates and their respective officers, directors, employees,
        agents and fiduciaries (each, a "Seller Indemnified Party")
        forever harmless from and against, and to promptly pay to a
        Seller Indemnified Party or reimburse a Seller Indemnified Party
        for, any and all Losses sustained or incurred by any Seller
        Indemnified Party relating to, resulting from, arising out of or
        otherwise by virtue of any of the following:

                  (a)  any misrepresentation or breach of a
        representation or warranty made herein by Buyer, or

        agreements contained in this Agreement or the Transaction
        Documents to be performed by Buyer;

                  (b)  any action, demand, proceeding, investigation or
        claim (whenever made) by any third party (including governmental
        agencies) against or affecting Seller which, if successful, would
        give rise to or evidence the existence of or relate to a
        misrepresentation or breach of any of the representations,
        warranties or covenants of Buyer in this Agreement or any
        Transaction Document;

                  (c)  any claim arising out of Buyer's failure to pay,
        satisfy or discharge the Assumed Liabilities, including, without
        limitation, liabilities under the Union Contract;

                  (d)  any claim for payment and/or expenses as a broker

        or consummation of this Agreement based upon an alleged agreement
        between claimant and Buyer or any of its affiliates;

                  (e)  any claim arising out of Buyer's failure to pay

        2.2 hereof; or

                  (f)  any claim for a Loss incurred by Seller relating
                                       31PAGE

        to the Letters of Credit.

             Buyer agrees to promptly pay to or reimburse a Seller
        Indemnified Party for all Losses incurred by such Seller
        Indemnified Party.

             7.3  Indemnification Procedure for Third Party Claims.  In
        the event that subsequent to the Closing any person or entity
        entitled to indemnification under this Agreement (an "Indemnified
        Party") asserts a claim for indemnification or receives notice of
        the assertion of any claim or of the commencement of any action
        or proceeding by any person or entity who is not a party to this
        Agreement or an affiliate of a party to this Agreement
        (including, but not limited to any domestic or foreign court or
        governmental authority, federal, state or local) (a "Third Party
        Claim") against such Indemnified Party, against which a party to
        this Agreement is required to provide indemnification under this
        Agreement (an "Indemnifying Party"), the Indemnified Party shall
        give written notice together with a statement of any available
        information regarding such claim to the Indemnifying Party within
        thirty (30) days after learning of such claim (or within such
        shorter time as may be necessary to give the Indemnifying Party a
        reasonable opportunity to respond to such claim).  The
        Indemnifying Party shall have the right, upon written notice to
        the Indemnified Party (the "Defense Notice") within thirty days
        (30) after receipt from the Indemnified Party of notice of such
        claim, which notice by the Indemnifying Party shall specify the
        counsel it will appoint to defend such claim ("Defense Counsel"),
        to conduct at its expense the defense against such claim in its
        own name, or if necessary in the name of the Indemnified Party;
        provided, however, that the Indemnified Party shall have the
        right to approve the Defense Counsel, which approval shall not be
        unreasonably withheld or delayed, and in the event the
        Indemnifying Party and the Indemnified Party cannot agree upon
        such counsel within ten (10) days after the Defense Notice is
        provided, then the Indemnifying Party shall propose an alternate
        Defense Counsel, which shall be subject again to the Indemnified
        Party's approval pursuant to this Section 7.3.

                  (a)  In the event that the Indemnifying Party shall
        fail to give the Defense Notice within the time period described
        above, it shall be deemed to have elected not to conduct the
        defense of the subject claim, and in such event the Indemnified
        Party shall have the right to conduct such defense in good faith
        and to compromise and settle the claim without prior consent of
        the Indemnifying Party and such Indemnifying Party will be liable
        for all reasonable costs, expenses, settlement amounts or other
        Losses paid or incurred in connection therewith.

                  (b)  In the event that the Indemnifying Party does
        deliver a Defense Notice within the time period described above
        and thereby elects to conduct the defense of the subject claim,
        the Indemnified Party will cooperate with and make available to
        the Indemnifying Party such assistance and materials as it may
                                       32PAGE

        reasonably request, all at the expense of the Indemnifying Party,
        and the Indemnified Party shall have the right at its expense to
        participate in the defense assisted by counsel of its own
        choosing, provided that the Indemnified Party shall have the
        right to compromise and settle the claim only with the prior
        written consent of the Indemnifying Party.

                  (c)  Without the prior written consent of the
        Indemnified Party, the Indemnifying Party will not enter into any
        settlement of any Third Party Claim or cease to defend against
        such claim, if pursuant to or as a result of such settlement or
        cessation, (i) injunctive or other equitable relief would be
        imposed against the Indemnified Party, or (ii) such settlement or
        cessation would lead to liability or create any financial or
        other obligation on the part of the Indemnified Party for which
        the Indemnified Party is not entitled to indemnification
        hereunder.

                  (d)  Notwithstanding paragraph (b) above, the
        Indemnifying Party shall not be entitled to control, and the
        Indemnified Party shall be entitled to have sole control over,
        the defense or settlement of any claim to the extent that claim
        seeks an order, injunction or other equitable relief against the
        Indemnified Party which, if successful, could materially
        interfere with the business, operations, assets, condition
        (financial or otherwise) or prospects of the Indemnified Party
        (and the reasonable cost of such defense shall constitute an
        amount for which the Indemnified Party is entitled to
        indemnification hereunder).  If the Indemnifying Party decides to
        accept and agree to an offer to settle a Third Party claim, which
        Third Party Claim the Indemnifying Party is permitted to settle
        under this Section 7.3, the Indemnifying Party will give written
        notice to the Indemnified Party to that effect within thirty (30)
        calendar days after its receipt of such notice.  If the
        Indemnified Party fails to consent to such offer within 30
        calendar days after its receipt of such notice, the Indemnified
        Party may continue to contest or defend such Third Party Claim
        and, in such event, the maximum liability of the Indemnifying
        Party as to such Third Party Claim will not exceed the amount of
        such settlement offer, plus reasonable costs and expenses paid or
        incurred by the Indemnified Party through the end of such 30-day
        period.

                  (e)  Any final judgment entered or settlement agreed
        upon in the manner provided herein shall be binding upon the
        Indemnifying Party, and shall conclusively be deemed to be an
        obligation with respect to which the Indemnified Party is
        entitled to prompt indemnification hereunder.


             7.4  Failure to Give Timely Notice.  A failure by an
        Indemnified Party to give timely, complete or accurate notice as
        provided in Section 7.3 will not affect the rights or obligations
        of any party hereunder except and only to the extent that, as a
                                       33PAGE

        result of such failure, any party entitled to receive such notice
        was deprived of its right to recover any payment under its
        applicable insurance coverage or was otherwise directly and
        materially damaged as a result of such failure to give timely
        notice.

             7.5  Certain Limitations.

                  (a)  Notwithstanding anything to the contrary set forth
        in this Agreement (but subject to the terms of this Section 7.5),
        Seller shall not be liable hereunder to Buyer as a result of any
        misrepresentation of any representation or warranty contained in
        this Agreement, unless and until the Losses incurred by all Buyer
        Indemnified Parties, in the aggregate, as a result of such
        misrepresentations under this Agreement shall exceed, in the
        aggregate, $100,000 (the "Basket Threshold"); provided, however,
        that once the Basket Threshold is reached, Seller shall fully
        indemnify Buyer (or a Buyer Indemnified Party) for all Losses,
        liabilities and damages incurred by Buyer (or a Buyer Indemnified
        Party), including the $100,000 applied to the Basket Threshold.
        The aggregate amount required to be paid by Sellers under Section
        7.1(a) and 7.1(f) shall not exceed the Purchase Price (the
        "Cap").  The parties agree that the (i) Basket Threshold and the
        Cap shall not apply to any breach of the representations and
        warranties contained in Sections 3.7(a), 3.13, 3.24 and 3.27; and
        (ii) Basket Threshold shall not apply to Section 7.1(e).

                  (b)  All of the representations and warranties set
        forth in this Agreement or in any of the other Transaction
        Documents shall survive the execution and delivery of this
        Agreement and the consummation of the transactions contemplated
        hereby, regardless of any investigation, inquiry or examination
        made for or on behalf of or any knowledge of Buyer or Sellers, or
        any of their respective affiliates, officers, directors,
        employees, agents, or representatives or the acceptance by any of
        them of any certificate or opinion, for a period of two years
        after the Closing and shall expire and terminate upon the
        expiration of such two year period, except the warranties and
        representations contained in (i) Section 3.7(a) concerning title
        of the Assets shall survive indefinitely, (ii) Section 3.24
        regarding Taxes shall survive until the expiration of all
        applicable statutes of limitations (including extensions of said
        statutes) and (iii) Section 3.27 regarding environmental
        liabilities shall survive indefinitely.  Seller shall only be
        liable for claims of which it receives notice of from Buyer
        within the applicable survival period.  In the event Buyer incurs
        a Loss and a claim is filed, prior to the end of such two year
        period, the termination date shall be extended until such claim
        is fully resolved and Buyer is appropriately indemnified for such
        Loss.  Unless a specified period is set forth in this Agreement
        or in a Transaction Document (in which event such specified
        period will control), all covenants contained in this Agreement
        and in any Transaction Document will survive the Closing and
        remain in effect indefinitely.
                                       34PAGE

                  (c)  Seller's liability for any claims made with
        respect to a breach or misrepresentation of the representations
        and warranties contained in Section 3.7(b) will be subject to the
        limitations set forth in Section 2.2(e), as well as the other
        limitations of this Section 7.5.

             8.3  Severability.  The unenforceability or invalidity of

        inure to the benefit of the parties hereto and their respective

        delegable by any party without the prior written consent of the
        other party; provided, however, that nothing in this Agreement is
        intended to limit Buyer's ability to assign its rights or
        delegate its responsibilities, liabilities and obligations under
        this Agreement to any of its affiliates or to lenders as security
        for borrowings, at any time whether prior to or following the
