           other rights of a stockholder of Perma-Fix.
 
    3.3.5  No Liability.  Neither Perma-Fix nor Chem-Met shall be
           liable to any holder of shares of Chem-Met Common Stock

                     or with any officers or employees; or

                     Public Accountants) suffered by Chem-Met which
                     is material to Chem-Met, or any waiver by

           the business combination to be effected by the Merger

                                11

           as a pooling of interests or (ii) prevent the Merger

           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
           outstanding order, judgment, decree, stipulation, or

           confidentiality measures regarding the Chem-Met
           Intellectual Property Rights. Chem-Met has not given

           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 their 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
           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,

                                  14

           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.

         nor the Sullivan Trusts is a party to, bound by, or a bene-
         ficiary of, any agreement which could prevent the use of
         assets material to Chem-Met or the conduct of business as

         directors, officers, agents, or any other individual (or any
         of their respective heirs, legatees, beneficiaries, or legal
         representatives) with respect to profit-sharing, pension or
         retirement benefits, or any other employee benefit of any kind
         whatsoever relating to Chem-Met or any of its employees, have
         been paid.  All legally enforceable obligations of Chem-Met,
         whether arising by operation of law, contract, agreement, or

         directors, officers, agents, or any other individual (or their
         respective heirs, legatees, beneficiaries or legal
         representative) relating to Chem-Met or any of the employees
         of Chem-Met with respect to periods ending on or before the
         Closing have been paid, or adequate accruals for payment
         thereof are reflected on the Audited Financial Statements. 
         Neither Chem-Met nor any of its Affiliates has any accumulated
         funding deficiencies, as such term is defined in the Employee
         Retirement Income Security Act of 1974 ("ERISA") and in the
         Code with respect to any employee benefit plan as defined in
         ERISA maintained or established for employees of Chem-Met. 
         Chem-Met has not incurred any liability to the Pension Benefit
         Guaranty Corporation ("PBGC") other than for the payment of
         insurance premiums all of which have been paid when due, the
         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 investiga-
         tions 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 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 experi-
         enced 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

                               22

         had any tax imposed upon it by the IRS for any alleged viola-
         tion under Section 4975 of the Code, or has engaged in any trans-
         action 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.

    that, in the event any of the Sullivans or any of the Sullivan
    Trusts breach or threaten to breach any of the provisions of

    to Perma-Fix, for which there is no adequate remedy at law. 
    It is accordingly agreed that in the event of a failure by any
    of the Sullivans or Sullivan Trusts to perform their obliga-
    tions 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 specif-

    Fix may be entitled, at law or in equity.

         purposes.

         accountants in connection with registration statements similar

         limitation, the following statements: (i) the combined Audited
         Financial Statements of Chem-Con and Chem-Met examined by them

         comply as to form in all material respects with the applicable
         accounting requirement of the Securities Act and of the
         published Rules and Regulations thereunder and (ii) on the
         basis of a reading of the latest available unaudited financial
         statements, inquiries of officers of Chem-Con and Chem-Met
         responsible for financial and accounting matters and a reading
         of the minutes, nothing has come to their attention which
         caused them to believe that (a) as of the date of the latest
         available unaudited consolidated interim financial statements
         prepared by Chem-Con and Chem-Met there was any change in the
         capital stock or long-term debt of Chem-Con, Chem-Met and

         consolidated Balance Sheet, or (b) for the period from
         September 30, 1998, to the date of the latest available
         unaudited interim consolidated financial statements prepared
         by Chem-Met, there were any decreases, as compared with the
         corresponding period in the preceding year, in consolidated
         net revenues or in total or per share amounts of consolidated
         income (loss) before extraordinary items or of consolidated
         net income, except in all instances for changes or decreases
         which the Proxy Statement discloses have occurred or may
         occur, and (c) that on the basis of inquiries of officers of
         Chem-Con and Chem-Met responsible for financial and accounting
         matters and a reading of the minutes, nothing has come to
         their attention which caused them to believe that (1) at a
         specified date within five (5) days of the Effective Date of
         the Registration Statement and not more than five (5) days
         prior to the Effective Time of the Merger there was any change
         in the capital stock or long-term debt of Chem-Con and Chem-
         Met and their subsidiaries consolidated or any decreases in
         consolidated net current assets or in consolidated net assets,
         as compared with amounts shown on the September 30, 1998,
         consolidated Balance Sheet or (2) for the period from the date
         of the latest available unaudited consolidated interim
         financial statements prepared by Chem-Con and Chem-Met to a
         specified date within five (5) days of the effective date of
         the Registration Statement and not more than five (5) days
         prior to the Effective Time of the Merger there were any
         decreases as compared with the corresponding period in the
         preceding year, in consolidated net revenues or in the total
         or per-share amounts of consolidated income before
         extraordinary items or of consolidated net income, except in
         all instances for changes or decreases which the Proxy
         Statement and Registration Statement discloses have occurred
         or may occur, and (d) that they have compared the financial
         information which related to Chem-Con and Chem-Met appearing
         in the Proxy Statement and Registration Statement with amounts
         in the consolidated financial statements or accounting records
         of Chem-Con and Chem-Met and have found them to be in
         agreement.
