           patents, trademarks, trade names, service marks,
           copyrights, mask works, web domain addresses, and all
           processes, formulae, methods, schematics, technology,

           and tangible or intangible proprietary information or
           material that Chem-Met is licensed or otherwise
           possesses legally enforceable rights to use and are
           necessary to conduct the business of Chem-Met as currently
           conducted, or planned to be conducted, the absence of which would
           be reasonably likely to have a material adverse effect upon Chem-Met
           (the "Chem-Met Intellectual Property Rights").  None of the
           Chem-Met Intellectual Property Rights is subject to any outstand-
           ing order, judgment, decree, stipulation, or agreement restricting

           best of their knowledge none infringes on, or is being infringed
           by, other intellectual property rights of any other person or
           entity.  Chem-Met has promulgated and used commercially
           reasonable efforts to enforce and maintain any
           reasonably necessary trade secret or confidentiality
           measures regarding the Chem-Met Intellectual Property
           Rights. Chem-Met has not given and is not bound by an
           agreement or indemnification regarding Chem-Met

           property or service produced, used or sold by Chem-Met.

           Met is, or will as a result of the execution and
           delivery of this Agreement or the performance of their
           respective obligations under this Agreement or
           otherwise be, in breach of any license, sublicense or
           other agreement relating to the Chem-Met Intellectual
           Property Rights, or any material licenses, sublicenses
           and other agreements as to which Chem-Met is a party
           and pursuant to which Chem-Met is authorized to use any
           third party patents, trademarks or copyrights ("Chem-
           Met Third Party Intellectual Property Rights"),
           including software which is used in the manufacture of,
           incorporated in, or forms a part of any product sold or
           services rendered by or expected to be sold or services
           rendered by Chem-Met, the breach of which would be
           reasonably likely to have a material adverse effect
           upon Chem-Met, except as disclosed in Schedule "K"
           hereof.

    4.8.3  Year 2000 Issues.  Schedule "S" hereof identifies each
           "Year 2000" audit, report or investigation that has
           been performed by or on behalf of Chem-Met with respect
           to its business and operations, and Chem-Met has
           provided to Perma-Fix true and correct copies of all
           such audits, reports or investigations. Except as set
           forth in such audits, reports and investigations,
           neither the Sullivans, the Sullivan Trusts nor Chem-Met
           are aware of any failure to be Year 2000 Compliant of
           (i) any software products sold or licensed by Chem-Met
           to third parties or (ii) any computer software products
           used by or licensed to Chem-Met from third parties for
           internal use by Chem-Met. For purposes of this
           Agreement, "Year 2000 Compliant" means, with respect to
           each software product referred to in the prior
           sentence, that such system (i) will accurately receive,
           record, store, provide, recognize and process all date
           and time data from, during, into and between the
           twentieth and twenty-first centuries; (ii) will
           accurately perform all date-dependent calculations and
           operations (including, without limitation, mathematical
           operations, sorting, comparing and reporting) from,
           during, into and between the twentieth and twenty-first
           centuries; and (iii) will not malfunction, cease to
           function or provide invalid or incorrect results as a
           result of (x) the change of century, (y) date data,
           including date data which represents or references
           different centuries or more than one century or (z) the
           occurrence of any particular date; in each case without
           human intervention, other than original data entry;
           provided, in each case, that all applications, hardware
           and other systems used in conjunction with such system
           which are not owned or licensed by Chem-Met correctly
           exchange date data with or provide data to such system.
           Chem-Met has not provided any guarantee or warranty for
           any product sold or licensed, or services provided, by
           Chem-Met to the effect that such product or service (i)
           complies with or accounts for the fact of the arrival
           of the year 2000 or (ii) will not be adversely affected
           with respect to functionality, operability, performance

                                12


           or volume capacity (including without limitation the
           processing and reporting of data) by virtue of the
           arrival of the year 2000.  Chem-Met has performed
           audits regarding its primary suppliers, customers,
           creditors and financial service organizations with
           which they have substantial interaction ("Outside
           Persons") and has determined that all of these Outside
           Persons are substantially Year 2000 Compliant to the
           extent that there will be no material adverse effects
           to Chem-Met resulting from a failure of such Outside
           Persons to be Year 2000 Compliant.  In addition,
           Schedule "S" shall set forth in detail the status of
           Chem-Met's efforts to address the Year 2000  issues
           relating to Chem-Met and such Outside Persons.

         IRS or the Department of Labor ("DOL") with respect to any
         such employee benefit plan that affects, or might affect Chem-
         Met, and does not have any withdrawal liability with respect
         to any multiemployer pension plan ("Multiemployer Plan") which
         is subject to the Multiemployer Pension Plan Amendments Act of
         1980.  The consummation of this Agreement will not result in
         either a complete or partial withdrawal from any of the
         Multiemployer Plans.  All of the employee benefit plans of
         which Chem-Met or any Affiliate of Chem-Met is the plan
         sponsor relating to Chem-Met or any of their employees have
         been amended as, when and to the extent necessary to comply
         with and qualify under the applicable provisions of the Code;
         and all such employee benefit plans have been administered in
         accordance with the applicable provisions of the Code and
         ERISA.  Except as indicated on Schedule "N", any employee
         benefit plans relating to Chem-Met or any of their employees
         which are pension benefit plans have received, or have applied
         for and expect to receive, determination letters from the IRS
         to the effect that such plans are qualified and exempt from
         federal income taxes under Sections 401(a) and 501(a), respectively,
         of the Code, and, no amendments have been made to any such
         employee benefit plans other than those covered by such
         determination letters or applications for such determination
         letters with respect to such amendments which have been timely
         filed with the IRS.  No determination letter received with
         respect to any employee benefit plan relating to Chem-Met or
         any of its employees has been revoked nor has revocation been
         threatened.  Each of the employee benefit plans have been
         administered at all times and in all respects in accordance
         with their respective terms.  There are no pending
         investigations by any Governmental Authority involving any
         employee benefit plans relating to Chem-Met or any of its
         employees, no deficiency or termination proceedings involving
         such employee benefit plans, and no threatened or pending
         claims (except for claims for benefits payable in the normal
         operation of the employee benefit plans), suits or proceedings

                                     20


         against any such employee benefit plan or asserting any
         rights or claims to benefits under any such employee benefit
         plan nor are there any facts which could give rise to any
         liability in the event of any such investigation, claim, suit
         or proceeding.  Neither the employee benefit plans nor any
         trusts created thereunder relating to Chem-Met or to any of
         their employees, nor any trustee, administrator or other
         fiduciary thereof, has engaged in a "prohibited transaction"
         (as such term is defined in Section 4975 of the Code or Section 406 of
         the ERISA); and has not experienced any reportable event within
         the meaning of ERISA or other event or condition which
         presents a material risk of termination of any such employee
         benefit plan by the PBGC, has had any tax imposed upon it by
         the IRS for any alleged violation under Section 4975 of the Code, or
         has engaged in any transaction which might subject Chem-Met or
         any such employee benefit plan to any liability for such tax.
         The terms of any such employee benefit plans comply with ERISA
         and the Code in all respects, and, any and all reporting and
         disclosure requirements of ERISA or the Code and the DOL with
         respect to any such employee benefit plan have been timely
         met.  The information supplied to the actuary by Chem-Met, the
         Sullivans or the Sullivan Trusts for use in preparing those
         reports was complete and accurate and none of Chem-Met, the
         Sullivans nor the Sullivan Trusts has reason to believe that
         the conclusions expressed in such reports are incorrect.  In
         the event of termination of any employee benefit plan of Chem-
         Met or any of its Affiliates relating to Chem-Met or to any of
         their employees, there will be no liability of Chem-Met or the
         plan with respect to the providing of benefits accrued
         thereunder subject to future variations in levels of
         compensation assuming continued investment returns at rates
         actuarially predicted.  Further, if termination (whether
         complete or partial) of any plan has occurred, then, all
         liabilities with respect thereto have been satisfied in full
         and no present liability exists with respect to any such prior
         termination.  Schedule "N" also includes a list of any and all
         pension or benefit obligations of Chem-Met and/or its
         Affiliates which have not been fully funded.

4.21     Condition of Plant, Machinery and Equipment.  Except as set
         forth on Schedule "O", all of the items of the property, plant
         and equipment owned, operated or leased by Chem-Met is, in all
         material respects, in good condition and repair, reasonable
         wear and tear excepted, and Chem-Met agrees to maintain such
         items in good operating condition until the Closing.  Casualty
         losses to such property, plant and equipment are covered by
         insurance with normal industry deductibles being applicable.

4.22     Books of Account.  Chem-Met has maintained its books of
         account in accordance with GAAP, applied on a consistent basis
         with prior periods.

4.23     Stock Redemptions.  There are no shares of Chem-Met Common
         Stock which are subject to redemption or purchase in lieu of
         redemption, which prior to September 30, 1998, were not paid
         for in full.  From September 30, 1998, through the date of
         this Agreement, Chem-Met has not purchased or redeemed or
         entered into any agreement to purchase or redeem any Chem-Met
         Common Stock.
                                  21

4.24     Minute Books. Chem-Met have maintained their corporate minute
         books and all such books are current.

4.25     Indebtedness of Shareholders, etc.  Except as set forth on
         Schedule "P", none of the shareholders, Affiliates, officers,
         directors or employees of Chem-Met is (i) indebted to Chem-
         Met, and Chem-Met is not indebted to their Affiliates, share-
         holders or any of their officers, directors or employees, (ii)
         a party to or has any interest in a material contract, agree-
         ment or lease with Chem-Met or in which Chem-Met is a party to
         or bound by, or (iii) a customer or supplier of Chem-Met,
         which during any one of the preceding three (3) years supplied
         to or purchased from Chem-Met a amount of property or services
         exceeding Ten Thousand Dollars ($10,000.00) in any one (1)
         year.

4.26     Business Prospects.  Since September 30, 1998, there has not
         occurred any event or other occurrence which might have a
         material adverse effect on the business or business prospects
         of Chem-Met.

4.27     Bank Accounts; Powers of Attorney.  Schedule "Q" attached
         hereto sets forth each bank account and borrowing resolution
         authorizing officers or agents of Chem-Met to borrow money and
         lists the persons authorized to transact business on behalf of
         Chem-Met with respect to each such account or borrowing reso-
         lution.  Schedule "Q" also lists all powers of attorney
         granted by Chem-Met to any other person.

4.28     Sensitive Payments.  Chem-Met has not made or received, and to
         its best  knowledge, after reasonable due inquiry, none of
         their officers, directors, employees, agents, shareholders or
         other representative of Chem-Met or any person acting on
         behalf of Chem-Met, has made or received, directly or
         indirectly, any bribes, kickbacks, illegal political contri-
         butions with corporate funds, improper payments from corporate
         funds that are falsely recorded on the books and records of
         Chem-Met, payments to governmental officials in their
         individual capacities or illegal payments from corporate funds
         to obtain or retain business.

                     or entity, other than Perma-Fix or any of its
                     subsidiaries, any customer lists, or identify
                     any of the customers of Chem-Met, Chem-Con or
                     any of their subsidiaries or Affiliates; or,


                                24


           5.3.3.2   solicit, induce or in any manner attempt to

                     Affiliates.

5.4 Specific Enforcement.  The parties hereto recognize and agree
    that, in the event any of the Sullivans or any of the Sullivan
    Trusts breach or threaten to breach any of the provisions of
    this Article 5, immediate irreparable injury would be caused

    It is accordingly agreed that in the event of a failure by any
    of the Sullivans or Sullivan Trusts to perform their
    obligations under this Article 5, Perma-Fix shall be entitled
    to specific performance through injunctive relief to prevent
    breaches of any provision of this Article 5 and to

    and provisions thereof in any action instituted in any court
    of the United States or any state thereof having subject
    matter jurisdiction, in addition to any other remedy to which
    Perma-Fix may be entitled, at law or in equity.

         long-term debt of Chem-Con and Chem-Met and their subsidiaries

         and Affiliates incurs and suffers, or may incur or suffer, at
         any time as a result of or in connection with the Four County
         Landfill; provided however, that the Sullivans and the
         Sullivan Trusts (i) shall not have any liability under this
         Section 11.2 if there are no claims or demands, or a series
         of claims or demands,  against Perma-Fix or Chem-Met and/or
         any of their officers, directors, employees, agents,
         representatives or Affiliates that exceed,  in the aggregate,
         $900,000 relating to or in connection with the Four County

         Perma-Fix or Chem-Met or any of their officers, directors,
         employees, agents, representatives or Affiliates in excess of
         $900,000.00 relating to or in connection with, or arising out
         of the Four County Landfill, and any withdrawal by the
         Indiana Department of Environmental Management ("IDEM") of
         IDEM's approval of the Agreed Order (as defined below)
         between Chem-Met, IDEM, Office of the Indiana Attorney
         General, Four County Landfill Group and their respective
         members and the Four County Landfill Operable Unit #1 RD/RA
         Group and their respective members, executed by the parties
         to the Agreed Order during February 1999, relating to
         Chem-Met's settlement of any and all claims, liabilities or

                                47


         obligations of Chem-Met relating to or in connection with the
         Four County Landfill (the "Agreed Order") as a result of
         timely comments and objections filed during the notice and
         thirty (30) day comment period contemplated by the Agreed
         Order.  The Sullivans, the Sullivan Trusts, Perma-Fix and
         Chem-Met further agree that if the prior approval by IDEM of
         the Agreed Order is not withdrawn within a reasonable period
         following the expiration of the notice and thirty (30) day
         comment period contemplated by the Agreed Order and the final
         resolution of any timely comments or objections submitted or
         asserted with respect thereto, the obligation of the
         Sullivans and the Sullivan Trusts under this Section 11.2
         shall terminate.

11.3     Notice of Claim.  Perma-Fix shall give the Sullivans and the
         Sullivan Trusts a written notice (the "Notice of Claim")
         within ninety (90) days of the discovery of any matter in
         respect of which the right to indemnification contained in
         Section 11 can be claimed.  Notwithstanding the foregoing,
         failure to give such notice will not terminate any obligation
         of the Sullivans and the Sullivan Trusts hereunder.

11.4     Survival of Representations and Remedies.  All representa-
         tions and warranties contained in this Agreement shall
         survive the Closing, regardless of the investigation made by
         either party hereto.  This Agreement and all covenants and
         agreements contained in this Agreement shall survive the
         Closing.
