   Item 2.  Acquisition or Disposition of Assets

       On October 6, 1997 (the "Closing Date"), Thermo Remediation Inc. (the
   "Company") sold its 50% limited liability company interest in
   RETEC/TETRA, L.C., a Texas limited liability company (the "Joint
   Venture"), to TETRA Thermal, Inc. (the "Buyer"). Prior to this sale, the
   Buyer held the other 50% limited liability company interest in the Joint
   Venture. The Joint Venture, established in August 1992, engages in the
   business of installing and operating systems to process hazardous and
   nonhazardous wastes at petroleum refineries located primarily in the Gulf
   Coast region of the United States.
        The selling price for the Company's interest in the Joint Venture
   was $8,825,000 in cash. The selling price is subject to post-closing
   adjustments in the event of certain further sales of interests in the
   Joint Venture or its assets within six months after the Closing Date.
   Under the terms of the agreement originally establishing the Joint
   Venture, either party to the agreement had the right to propose a value
   for a 50% interest in the Joint Venture (the "Proposing Party") and to
   cause the other party (the "Electing Party") either to (i) buy the
   Proposing Party's interest in the Joint Venture at such price or (ii)
   sell the Electing Party's interest in the Joint Venture to the Proposing
   Party at such price. The selling price was proposed by the Buyer and the
   Company elected to sell the Buyer its interest in the Joint Venture at
   such selling price.
        The disposition was made pursuant to a Purchase and Sale Agreement
   (the "Agreement") executed on October 6, 1997, by and among the Company's
   Remediation Technologies, Inc. and RETEC Thermal, Inc. subsidiaries, as
   well as the Buyer and its TETRA Technologies, Inc. affiliate. In the
   Agreement, the Buyer and its affiliate agreed, subject to certain
   exceptions, to indemnify the Company and its subsidiaries against claims
   arising out of the operations, debts and liabilities of the Joint Venture
   arising both before and after the Closing Date. The terms of the
   Agreement were determined by arms' length negotiation among the parties.

                 Not applicable.

             (b) Pro Forma Condensed Financial Information

       The following unaudited pro forma condensed financial statements set
   forth the results of operations for the fiscal year ended March 29, 1997,
   and the three months ended June 28, 1997, as if the sale of the Company's
   investment in the Joint Venture had occurred at the beginning of fiscal
   1997. The unaudited pro forma condensed balance sheet sets forth the
   financial position as of June 28, 1997, as if the sale of the Company's
   investment in the joint venture had occurred as of that date.
       The pro forma results of operations are not necessarily indicative of
   future operations or the actual results that would have occurred had the
   sale of the Company's investment in the Joint Venture been consummated at
   the beginning of fiscal 1997. These statements should be read in
   conjunction with the accompanying notes herein and the historical
   consolidated financial statements and related notes of the Company

                                               Chief Accounting Officer


                                                                EXHIBIT 2.1

                           PURCHASE AND SALE AGREEMENT

             On this 6th day of October, 1997, but to be effective as of
        the 1st day of September, 1997, Remediation Technologies, Inc., a
        Delaware corporation ("RETEC"), RETEC THERMAL, INC., a Delaware
        corporation ("Seller"), TETRA Technologies, Inc., a Delaware
        corporation ("TETRA") and TETRA THERMAL, INC., a Delaware
        corporation ("Buyer"), hereby act and agree as follows:

                                   WITNESSETH:

             WHEREAS, Seller is a wholly-owned subsidiary of RETEC;

             WHEREAS, Buyer is a wholly-owned subsidiary of TETRA;

             WHEREAS, Seller and Buyer formed RETEC/TETRA, L.C. (the
        "LLC") effective as of August 1, 1992 pursuant to the Formation
        Agreement and Regulations of the LLC by and between Seller,
        Buyer, TETRA and RETEC (the "Formation Agreement");

             WHEREAS, Seller and RETEC desire to sell to Buyer and Buyer
        and TETRA desire to purchase from Seller all of Seller's
        interests in the LLC and all Projects, all on the terms and
        conditions hereinafter set forth.

             NOW, THEREFORE, in consideration of the mutual covenants,
        conditions, and agreement hereinafter provided, the parties agree
        as follows:

        I.   Definitions

             Capitalized terms not otherwise defined herein shall have
        the meanings set forth in the Formation Agreement.

        II.  Purchase and Sale of Limited Liability Company Interest

             2.1  Subject to and upon the terms and conditions of this
        Agreement, Seller hereby agrees to transfer, sell and assign to
        Buyer and Buyer hereby agrees to purchase from Seller all of
        Seller's right, title and interest in and to Seller's Limited
        Liability Company Interest in the LLC (including all of Seller's
        interests in all Projects). 

             2.2  The base purchase price ("Base Purchase Price") is
        US$8,825,490, subject to adjustment as provided in Section 2.4
        below.

             2.3   Buyer shall assume certain of the liabilities of the
        LLC, and defend RETEC and Seller against claims arising out of
        the operations of the LLC, or its successors, pursuant to an
        Assignment and Assumption Agreement (the "Assumption Agreement")
        in the form attached hereto as Exhibit 2.3.

             2.4  If, within six (6) months after the Closing Date, Buyer
        or any affiliated entity of Buyer (including the LLC or TETRA)
        enters into any agreement under which any such party is committed
        to sell to Scaltech, Inc. 50% or more of the outstanding capital
        stock of Buyer, or of the Limited Liability Company Interests of
        the LLC, or of their successors, or of their assets, or merge or
        consolidate the Buyer, the LLC, or their successors, to or with
        Scaltech, Inc. (the "Acquiring Entity"), or upon the occurrence
        of a similar event, such that the total valuation of the equity
        or assets of the Buyer, the LLC or their successors in any such
        sale, merger or consolidation or similar event  (the "Sale
        Valuation") exceeds the sum of twice the Base Purchase Price plus
        equity contributions to the LLC from TETRA after the Closing Date
        (such sum shall be referred to herein as the "Adjusted
        Valuation"), the purchase price of this transaction will be
        subject to adjustment as follows.  In this circumstance, Buyer
        will pay to Seller, as additional purchase price ("Additional
        Purchase Price"), 50% of the amount calculated by subtracting
        from the Sale Valuation the Adjusted Valuation.  For example, if
        in such six month period any Acquiring Entity purchased the LLC
        from TETRA for $20,000,000 and TETRA had contributed an
        additional $2,000,000 in equity to the LLC, the Additional
        Purchase Price owed to Seller will be $250,000. 

             2.5  Upon completion of the closing as set forth in section
        3.2, this Agreement shall operate as an acknowledgment and
        agreement of the parties hereto that, after the Closing Date, no
        ongoing rights or obligations of any kind exist between or among
        TETRA, Seller, RETEC, Buyer and/or the LLC under the Formation
        Agreement or any agreement or document referenced in or at any
        time attached to the Formation Agreement, or under any agreement
        relating to borrowings of the LLC, or any other agreement,
        document, instrument or certificate entered into or delivered by
        a party, except as set forth in this Purchase and Sale Agreement,
        the Assumption Agreement or other agreement or instrument to be
        delivered pursuant to this Purchase and Sale Agreement.

        III. The Closing; Payment of Purchase Price

             3.1  The closing is being held at the offices of the LLC on
        the date hereof (the "Closing Date").

             3.2  At the closing:

             (i)  Buyer shall pay to Seller the amount of US$8,825,490 by
                  wire transfer of good funds to the account designated
                  by Seller; 

             (ii) Seller shall deliver to Buyer a certificate
                  representing Seller's Limited Liability Company
                  Interest in the LLC, duly endorsed for transfer to
                  Buyer.

            (iii) The parties each shall deliver to the other an executed
                  Assumption Agreement in the form attached hereto as
                  Exhibit 2.3.

             (iv) There shall be delivered to RETEC and Seller a written
                  statement from the Texas Commerce Bank releasing each
                  of RETEC and Seller from any Guaranty of the payment by
                  the LLC of any debt or obligation owed by the LLC,
                  TETRA or Buyer to the Texas Commerce Bank or any of its
                  affiliates and waiving any claim against RETEC or
                  Seller for payment of the debts or obligations of the
                  LLC, TETRA or Buyer.

             (v)  RETEC and Seller shall cause all of its employees who
                  hold any offices as members of the Managing Board,
                  Managers or officers of the LLC to submit written
                  resignations of such offices and shall deliver such
                  written resignations to Buyer.

             3.3  If Additional Purchase Price is owed to Seller, Buyer
        will pay such amount by cashier's check or wire transfer at such
        time, or times as Buyer receives payment from the Acquiring
        Entity.  If the Acquiring Entity pays in installments, Buyer will
        pay Seller promptly upon receipt of each installment an amount
        calculated by multiplying the percentage of the total amount owed
        by the Acquiring Entity represented by the installment times the
        Additional Purchase Price.

        IV.  Representations and Warranties

             4.1  RETEC and Seller, jointly and severally, represent and
        warrant to TETRA and Buyer that, as of the date hereof, other

             thermal volatilization and steam stripping, with indirect
             heat transfer primarily employed in the desorber, rather
             than combustion.

             "Thermal Desorption System" means a system for operation and
             use of the Thermal Desorption process, comprised of four
             primary subsystems - an input materials feed system, a

             based mixture for injection into one of several thermal
             cracking operations in a petroleum refinery.

             "Waste Derived Fuel System" means a system for the
             separation of organics, water and solids from oily solids
             and sludges, including watery solids and sludges, and
             subsequent drying of the solids and sludges to produce a
             "Dry Fuel" and/or particle sizing the solids and mixing it
             with liquid hydrocarbons to produce a "Wet Fuel" for use as
             a commercial fuel, typically, but not limited to, cement
             kilns.

             (d)  The listing of business areas in paragraph (a) above is
        intended solely for purposes of circumscribing The Selling
        Group's obligations not to compete with the LLC and shall not be
        deemed or construed to limit or in any way constrain the

        Buyer to fully perform any defense obligation or to discharge and
        pay all LLC Liabilities (as defined in the Assumption Agreement)
        assumed by Buyer and the LLC under the Assumption Agreement.

        following sentence.  With respect to any claims by TETRA, Buyer
        or the LLC for indemnification arising out of or relating to an
        Infringement Claim, (A) RETEC and Seller shall be obligated to
        pay at any time only one-half of amounts actually paid by TETRA,
        Buyer and the LLC to third parties in the defense of such Claims,

        said Patents, or as royalties under a license to use or practice
        said Patents,  (B) RETEC's and Seller's entire liability to
        TETRA, Buyer and the LLC relating to the defense and settlement

             6.3  If the LLC or any of the parties to this Agreement
        shall receive notice of any claim or alleged claim asserting the
        existence of a Liability as to which a party may be indemnified
        hereunder, the party to be indemnified (the "Indemnified Party")
        shall promptly notify the party 
        expected to defend and  indemnify the Indemnified Party thereof,
        setting forth in reasonable detail the basis on which such right
        to defense and indemnity is asserted.

             6.4  With respect to any suit, action, investigation, claim
        or proceeding for which defense and indemnification is claimed by
        the Indemnified Party, the Indemnified Party shall have the
        right, but not the obligation, to participate at its own expense
        in the defense thereof by counsel of its own choosing, but the
        Indemnifying Party shall be entitled to control the defense
        unless the Indemnified Party has relieved the Indemnifying Party
        from liability with respect to the particular matter.   
        Regardless of whether the Indemnified Party elects to participate
        in the defense, the Indemnifying Party shall reimburse the

        or proceeding, the Indemnified Party shall have the right, but
        not the obligation, to defend, contest or otherwise protect
        against the same, and make any compromise or settlement thereof
        and recover the entire cost thereof from the Indemnifying Party,
