Item 2.   Acquisition or Disposition of Assets

         During the third quarter of 1996, Molten Metal Technology, Inc. (the
"Company") signed a letter of intent to become the full owner of the Quantum
Catalytic Extraction Processing ("Q-CEP[Trademark]") facility it had jointly
owned with The Scientific Ecology Group, Inc. ("SEG") in Oak Ridge, Tennessee
(the "Q-CEP Facility") and to acquire certain assets used for handling and
processing radioactive "wet waste." SEG is a wholly-owned subsidiary of
Westinghouse Electric Corporation ("Westinghouse"). The Q-CEP Facility is
designed to process radioactive ion exchange resins from nuclear power plants.
On December 10, 1996, the Company, MMT of Tennessee Inc., a wholly-owned
subsidiary of the Company ("MMT Tennessee"), SEG and Westinghouse executed
definitive agreements with respect to such acquisition. Pursuant to those
agreements, MMT Tennessee acquired SEG's interest in the Q-CEP Facility and
certain assets of SEG and Westinghouse used in the "wet waste" business. These
assets include contracts, equipment, services and personnel for processing
radioactive waste streams at the Q-CEP Facility. MMT Tennessee will own and
operate the Q-CEP Facility and the "wet waste" business.

         The purchase price for these assets was $31 million in cash, which
was based on the parties' mutual agreement as to the fair market value of the
assents being acquired. Payment of the purchase price was funded from the
Company's working capital.

                  Seller;

                           (vii) no labor organization (whether certified or
                  not) represents or to the Seller's knowledge purports to
                  represent any of the Proposed Assumed Employees; and

                           (viii) the Seller has not experienced any labor
                  strike, dispute, slow-down or similar work stoppage in the
                  last three years.

                  (a)      SCHEDULE 5.15(a) hereto sets forth a complete and 
         accurate list of all patents, trademarks, trade names and copyrights
         owned by and registered in the name of the Seller or Westinghouse and

<PAGE>   23
                                      -17-


         the ownership and operation by the Seller or Westinghouse of the
         Acquired Assets or the conduct by the Seller of any of the Processing
         Activities. The General Signal Agreement represents the only agreement
         relating to Intellectual Property in effect on the date hereof which
         the Seller or Westinghouse has licensed or authorized for use by others
         or which has been licensed or authorized for use to the Seller or
         Westinghouse in connection with the Q-CEP Plant and the ownership or
         operation of the Acquired Assets or the conduct by the Seller of any of
         the Processing Activities.

                  (b) Except to the extent set forth in SCHEDULE 5.15(b) hereto,
         the Seller and Westinghouse own or have the sole and exclusive right to
         use, and the Acquired Assets will include, all Intellectual Property
         used or necessary for the conduct by the Seller of its activities as of
         the date hereof pursuant to the Master Agreement or the conduct as of
         the date hereof by the Seller of any of the Processing Activities, and
         the consummation of the Closing will not alter or impair any such
         right. Except as set forth in SCHEDULE 5.15(b), no royalties are paid
         or payable by the Seller or Westinghouse on or with respect to any of
         the Intellectual Property, and upon the consummation of the Closing no
         additional royalties (other than those already specified in SCHEDULE
         5.15(b)) shall be payable with respect to such Intellectual Property.

                  (c) The Seller and Westinghouse have complied with all of
         their obligations of confidentiality in respect of the Intellectual
         Property of others and to the knowledge of the Seller there are no
         violations of such obligations of confidentiality as are owed to the
         Seller or Westinghouse, except for any non-compliance or violations
         that singly or in the aggregate would not have a Material Adverse
         Effect.

                  (d) Except as set forth in SCHEDULE 5.15(d), to the knowledge
         of the Seller, no employee, agent or consultant of the Seller or
         Westinghouse is subject to confidentiality restrictions in favor of any
         third Person the breach of which would have a Material Adverse Effect.

                  (e) No claims are pending, and to the knowledge of the Seller
         no claims have been threatened, by any Person regarding use of any
         Intellectual Property used or necessary for the conduct by the Seller
         of its activities as of the date hereof pursuant to the Master
         Agreement or the conduct as of the date hereof of any of the Processing
         Activities, or challenging or questioning the validity or effectiveness
         of any license or agreement relating to any such Intellectual Property
         and to the Seller's knowledge there is no basis for any such claim
         except in the case of any of the foregoing for any claims that
         individually or in the aggregate will not 

<PAGE>   24
                                      -18-

         have a Material Adverse Effect. To the knowledge of the Seller, the use
         by the Seller or Westinghouse of the Intellectual Property listed in
         any part of SCHEDULE 5.15(a) does not conflict with or infringe on the
         rights of any Person and the Seller has not received any claim or
         written notice from any Person to such effect, except for any
         conflicts, infringements or violations that singly or in the aggregate
         will not cause any Intellectual Property listed on SCHEDULE 5.15(a)-(d)
         hereto to no longer be available to the Seller or Westinghouse or
         otherwise have a Material Adverse Effect. To the knowledge of the
         Seller, no third party is infringing, violating or otherwise using, in
         an unauthorized manner, the Intellectual Property of the Seller or
         Westinghouse relating to the Acquired Assets or the conduct of any of
         the Processing Activities, except for any conflicts, infringements or
         violations that singly or in the aggregate will not cause any
         Intellectual Property to no longer be available to the Seller or
         otherwise have a Material Adverse Effect.

         5.16. BROKERS. Neither the Seller nor Westinghouse has retained,
utilized or been represented by any broker or finder in connection with the
transactions contemplated by this Agreement.

         7.1. Proposed Assumed Employees.
              --------------------------

                  (a) Attached hereto as SCHEDULE 7.1(a) is a list of the
         Seller's employees to whom the Buyer has made employment offers on
         behalf of the Buyer Sub, conditioned on the occurrence of the Closing
         (the "PROPOSED ASSUMED EMPLOYEES"). Those Proposed Assumed Employees
         who become employees of the Buyer are referred to in this Agreement as
         the "ASSUMED EMPLOYEES". The Buyer hereby confirms, and represents and
         warrants, to the Seller that the offers of employment to the Proposed
         Assumed Employees were for wages or salary at least equal to those
<PAGE>   26
                                      -20-


         currently paid to the Proposed Assumed Employees and that as of the
         Closing the Buyer Sub will provide the Assumed Employees with the
         benefits listed on SCHEDULE 7.1(b).
                            
                  (b) The Seller shall retain all responsibility for all
         employees of the Seller other than the Assumed Employees. Nothing in
         this Agreement shall obligate the Buyer or the Buyer Sub to make any
         offer of employment to anyone other than a Proposed Assumed Employee
         or, except as provided in paragraph (c) below, to provide continued
         employment to any employee, whether or not the subject of an employment
         offer from the Buyer or the Buyer Sub, for any specified period of time
         following the Closing Date, or to maintain the same terms of employment
         (including compensation and benefits) for any specified period of time
         following the Closing Date. Except as provided in this paragraph (b) or
         in a letter agreement dated as of the date hereof among the parties
         hereto, for a period ending on the first anniversary of the Closing
         Date the Buyer and the Buyer Sub and their Affiliates (which does not
         include M4 Environmental L.P. or its general partner (collectively,
         "M4") for purposes of this paragraph (b)) shall not, without the prior
         written consent of the Seller, directly or indirectly, solicit the
         employment of or employ or offer to employ any employee of the Seller,
         including, without limitation, any Proposed Assumed Employee who is not
         an Assumed Employee; PROVIDED THAT the Buyer and the Buyer Sub may
         solicit the employment of or offer employment to any persons after
         their employment has been terminated by the Seller or Westinghouse.
         During such one-year period the Buyer and the Buyer Sub shall not
         solicit, employ or offer to employ on behalf of M4 any employee of the
         Seller if the Buyer could not do so on its own behalf. In addition,
         during this one-year period the Buyer, the Buyer Sub and their
         Affiliates (other than M4) shall not employ any such employees even if
         such employees were first employed by M4, unless permitted under the
         proviso to the second preceding sentence. For a period ending on the
         first anniversary of the Closing Date, neither the Seller nor
         Westinghouse nor their Affiliates shall, without the prior written
         consent of the Buyer or the Buyer Sub, directly or indirectly, solicit
         the employment of or employ or offer to employ any employee of the
         Buyer or its Subsidiaries (including the Buyer Sub), including, without
         limitation, any Assumed Employee; PROVIDED THAT the Seller and
         Westinghouse and their Affiliates may solicit the employment of or
         offer employment to any persons after their employment has been
         terminated by the Buyer or one of its Subsidiaries.

                  (c) The Buyer and the Buyer Sub agree that, for a period of 60
         days after the Closing Date, they will not cause any of the Assumed
         Employees to suffer "employment loss", excluding any employment loss in
         connection with the completion of a project as contemplated by 29
         U.S.C. 
<PAGE>   27
                                      -21-



         [Section]2103, for purposes of the Worker Adjustment and Retraining
         Notification Act, 29 U.S.C. [Sections]2101-2109, and related
         regulations (the "WARN ACT") if such employment loss could create any
         liability for the Seller, unless the Buyer or the Buyer Sub delivers
         notices under the WARN Act in such a manner and at such a time that the
         Seller bears no liability with respect thereto. The Seller agrees that,
         for a period of 60 days after the Closing Date, it will not cause any
         of its employees to suffer an "employment loss", excluding any
         employment loss in connection with the termination of a project as
         contemplated by 29 U.S.C. [Section]2103, for purposes of the WARN Act
         if such employment loss could result in any liability for the Buyer or
         the Buyer Sub, unless the Seller delivers notices under the WARN Act in
         such a manner and at such a time that the Buyer and the Buyer Sub bears
         no liability with respect thereto.

                  (d) Westinghouse and the Buyer have retained Strategic
         Employee Services, Inc. to determine whether, in its professional
         opinion, the wages and benefits to be offered by the Buyer Sub to the
         Proposed Assumed Employees are comparable in the aggregate to the wages
         and benefits currently provided by the Seller. The parties agree to
         each pay one-half of the fees and expenses of Strategic Employee
         Services, Inc. to perform such study.

         7.2. Employee Benefit Plans.
              ----------------------

                  (a) Except as otherwise specifically provided in this Section
         7.2, effective as of the Closing Date each Assumed Employee who is an
         active participant in any Employee Benefit Plan shall cease to be an
         active participant and all Assumed Employees shall become immediately
         eligible to participate in each of the Buyer's Employee Benefit Plans.

                  (b) The Buyer and the Buyer Sub shall grant to each Assumed
         Employee credit for service with the Seller and Westinghouse prior to
         the Closing Date for the purpose of eligibility and vesting (but not
         benefit accrual) under any Employee Pension Benefit Plan (as defined in
         ERISA) maintained by the Buyer or the Buyer Sub.

                  (c) The Buyer and the Buyer Sub shall grant to each Assumed
         Employee credit for service with the Seller and Westinghouse prior to
         the Closing Date under any Welfare Benefit Plan (as defined in ERISA)
         maintained by the Buyer or the Buyer Sub and other welfare and fringe
         benefit arrangements which the Buyer Sub offers or negotiates for the
         Assumed Employees (including, to the extent offered or negotiated, but
         not limited to arrangements providing retiree health, disability,
         vacation, severance and sick time benefits) and shall grant credit for
         deductibles and co-payments previously paid, except that the Buyer Sub
         shall not be 

<PAGE>   28
                                      -22-


         required to provide such service credit for purposes of the Buyer's
         sabbatical program and "life cycle" account. The Welfare Benefit Plans
         of the Buyer and the Buyer Sub shall not exclude from coverage any
         pre-existing condition of any of the Assumed Employees or any of their
         respective covered dependents (other than conditions excluded or
         excludable as of the Closing Date as pre-existing conditions under the
         applicable Welfare Benefit Plan of the Seller). Any valid claims of any
         of the Assumed Employees or any of their respective covered dependents
         made against the Seller's Welfare Benefit Plans to the extent arising
         in connection with incidents occurring prior to the Closing Date shall
         be satisfied by the Seller under such plans. The Seller shall remain
         solely responsible for any and all claims for hospitalization or other
         confinement charges with respect to any Assumed Employee
         hospitalization or other confinement that commences prior to the
         Closing Date, in accordance with the terms and provisions of the
         Seller's plans and policies. Any valid claims of any of the Assumed
         Employees or any of their respective covered dependents made against
         the Welfare Benefit Plans of the Buyer and the Buyer Sub to the extent
         arising in connection with incidents occurring on or after the Closing
         Date shall be satisfied by the Buyer or the Buyer Sub under such plans.
         Promptly after the Closing the Seller shall pay to the Assumed
         Employees the amount of vacation and sick time accrued up to the
         Closing Date in accordance with the terms and provisions of the
         Seller's Welfare Benefit Plans.

                  (d) Effective as of the Closing Date, the Buyer shall have in
         effect a defined contribution plan that includes a qualified cash or
         deferred arrangement within the meaning of Section 401(k) of the Code
         (the "BUYER'S 401(k) PLAN") providing benefits as of the Closing to the
         Assumed Employees participating in the Westinghouse Savings Program
         and/or the Seller's Employees Retirement Savings Plan immediately prior
         to the Closing. Each Assumed Employee who was participating in the
         Westinghouse Savings Program and/or the Seller's Employees Retirement
         Savings Plan shall become a participant in the Buyer's 401(k) Plan as
         of the Closing. Assumed Employees shall receive credit for all service
         with the Seller and Westinghouse for purposes of eligibility and
         vesting under the Buyer's 401(k) Plan. As soon as practicable following
         the Closing Date, the Seller and Westinghouse shall cause to be
         transferred from the Seller's Employees Retirement Savings Plan and the
         Westinghouse Savings Program to the Buyer's 401(k) Plan assets having a
         fair market value equal to the aggregate value of the account balances
         of the (i) Assumed Employees and (ii) alternate payees under qualified
         domestic relations orders, each within the meaning of Section 414(p) of
         the Code, relating to Assumed Employees, in such plans as of the date
         of transfer (such transfer to be in notes evidencing loans to Assumed
         Employees from their account 
<PAGE>   29
                                      -23-


         balances and in cash). The Buyer shall cause the Buyer's 401(k) Plan to
         provide for the receipt of such transfer. The Buyer represents and
         warrants to the Seller and Westinghouse, and the Seller and
         Westinghouse represent and warrant to the Buyer and the Buyer Sub, that
         each has heretofore delivered to the other a true and correct copy of
         the most recent favorable determination letter issued by the Internal
         Revenue Service as to the qualified status of its respective plan
         described in this subsection and that, to the best of its knowledge,
         nothing has occurred since the date of such letter, including as a
         result of plan operation or legislative or regulatory developments,
         which would adversely affect such determination.

         7.3. General Assistance; Books and Records.
              -------------------------------------

                  (a) The Seller and Westinghouse agree that, on and after the
         Closing Date, during normal business hours, they will permit the Buyer
         and the Buyer Sub and their auditors to have access to and examine and
         take copies of all books and records of the Seller or Westinghouse
         relating to the Q-CEP Plant or the Processing Activities which are not
         delivered to the Buyer or the Buyer Sub pursuant to this Agreement and
         relating to (i) events occurring prior to the Closing and (ii)
         transactions or events occurring subsequent to the Closing which are
         related to or arise out of transactions or events occurring prior to
         the Closing, as the Buyer or the Buyer Sub may reasonably require.

                  (b) The Buyer and the Buyer Sub agree that, on and after the
         Closing Date, during normal business hours, they will permit the Seller
         and Westinghouse and their auditors to have access to and examine and
         take copies of all books and records relating to the Q-CEP Plant or the
         Processing Activities and transferred to the Buyer or the Buyer Sub as
         part of the Acquired Assets, as the Seller or Westinghouse may
         reasonably require.

                  (c) The Buyer and the Buyer Sub agree to provide such support
         (including the availability of personnel and records) as the Seller or
         Westinghouse may reasonably request to assist the Seller or
         Westinghouse in (i) defending any litigation, arbitration or other
         dispute-resolution proceeding relating to any casualty, personal
         injury, property damage, Equal Employment Opportunity Commission or
         other claims against the Seller and/or Westinghouse constituting part
         of the Excluded Liabilities, (ii) pursuing claims of the Seller and/or
         Westinghouse against insurers or other miscellaneous claims, or (iii)
         in examining or utilizing records referred to in this Section 7.3. The
         Seller and/or Westinghouse as applicable shall continue to direct all
         such litigation and shall be responsible for all costs (including legal
         fees and expenses incurred in 
<PAGE>   30
                                      -24-


         connection therewith). To the extent such support becomes overly
         burdensome, the Buyer and/or the Buyer Sub, as applicable, and the
         Seller and/or Westinghouse, as applicable, will agree on mutually
         acceptable reimbursement provisions relating to the time actually
         incurred by the other party's or parties' employees to reflect such
         burden.

                  (d) The Seller and Westinghouse agree to provide such support
         (including the availability of personnel and records) as the Buyer or
         the Buyer Sub may reasonably request to assist the Buyer or the Buyer
         Sub in (i) defending any litigation, arbitration or other
         dispute-resolution proceeding relating to any casualty, personal
         injury, property damage, Equal Employment Opportunity Commission or
         other claims (other than Excluded Liabilities), (ii) pursuing claims
         against insurers or other miscellaneous claims, or (iii) in examining
         or utilizing records referred to in this Section 7.3. The Buyer and/or
         the Buyer Sub shall direct all such litigation and shall be responsible
         for all costs (including legal fees and expenses incurred in connection
         therewith). To the extent such support becomes overly burdensome, the
         Buyer and/or the Buyer Sub, as applicable, and the Seller and/or
         Westinghouse, as applicable, will agree on mutually acceptable
         reimbursement provisions relating to the time actually incurred by the
         other party's employees to reflect such burden.

                  (e) The Buyer, the Buyer Sub, Westinghouse and the Seller each
         agree to preserve and protect all books, records, files and data to the
         extent they relate to the Q-CEP Plant or the Processing Activities
         prior to the Closing (i) maintained for the preparation of tax returns
         for a period of ten years after the Closing Date, and (ii) other than
         those described in (i) above, for a period of six years after the
         Closing Date.

                  (f) The Buyer, the Buyer Sub, Westinghouse and the Seller each
         agree not to destroy any files or records which are subject to this
         Section 7.3 (i) for the periods described in clause (e) of this Section
         7.3 and (ii) thereafter, without giving at least thirty (30) days'
         notice to the other parties. Upon receipt of such notice, such other
         party may (i) cause to be delivered to it the records intended to be
         destroyed, at such other party's expense or (ii) notify the first party
         that such other party will pay the cost of storing and maintaining such
         books and records (including any necessary costs of moving such books
         and records to a location under control of such other party).

                  (g) Each party may take such action as it deems reasonably
         appropriate to separate or redact information unrelated to the Q-CEP
         Plant or the Processing Activities prior to the Closing from documents
         and other materials requested and made available pursuant to this
         Section 7.3 and, to 
<PAGE>   31
                                      -25-


         the extent not adequately addressed by Article 8, to condition access
         to materials that it deems confidential to the execution and delivery
         of an agreement in customary form by the requesting party not to
         disclose or misuse such information.

         7.4.     GUARANTIES AND INDEMNITIES. Attached as SCHEDULE 7.4 is a list
of existing bonds, letters of credit, guaranties and similar credit supports
outstanding in connection with the Q-CEP Plant or the Processing Activities (the
"SUPPORT AGREEMENTS"). The Buyer Sub agrees to use commercially reasonable
efforts, which will not include the payment of any consent fee or similar
amount, but which will include the provision of substitute security of like
character, quality and amount, to obtain the release of the Seller from those
Support Agreements indicated as "To Be Released" on SCHEDULE 7.4. The Buyer Sub
will consult with the Seller from time to time concerning the progress made with
respect to any such releases, and will permit the Seller reasonable
participation in such process. In the event that any such Support Agreements are
not released prior to the Closing, the Buyer and the Buyer Sub will indemnify
the Seller with respect to such Support Agreements on the terms set forth in
Section 10.2(b).

         7.5.     Radioactive Material License.
                  ----------------------------

                  (a) The Seller and the Buyer Sub will mutually control the
         shared boundary between their properties consistent with the dose
         limits and plan outlined in the Seller's and the Buyer's joint October
         9, 1996 correspondence to the Tennessee Division of Radiological
         Health, which provides that no individual occupational worker will
         receive more than 500 mrem/year based on a 20% occupancy factor. The
         Seller and the Buyer Sub each will survey the shared boundary for dose
         limits on a weekly basis and exchange all survey information.

                  (b) The Seller and the Buyer Sub each agrees to limit exposure
         so that neither will utilize more than half of the 500 mrem/year
         allocated exposure level (I.E., no more than 250 mrem/year of exposure
         at the fenceline for each of the Seller and the Buyer Sub). Neither
         party shall exceed the 250 mrem/year limit without the prior written
         consent of the other party. The liability for any violation of the
         exposure level shall be the responsibility of the party which caused
         such violation.

                  (c) A Radiation Safety Officer from each of the Seller and the
         Buyer Sub will meet not less than quarterly to mutually review the
         boundary's radiological situation and assure that the agreed controls
         on each side are sufficiently maintained to assure compliance. If such
         Radiation Safety Officers cannot resolve any issues which arise
         regarding 
<PAGE>   32
                                      -26-


         the shared boundary, these issues will be referred to the Executive
         Committee for resolution.

         7.6.     Radiologic Air Emissions.
                  ------------------------

                  (a) The Seller and the Buyer Sub will each collect radiologic
         emissions data from continuous stack emissions monitoring systems on an
         annual basis.

                  (b) Neither the Seller nor the Buyer Sub shall permit its
         stack source radiologic emission level to exceed 10 mrem/yr, or such
         other amount allowed by applicable Law. The liability for any violation
         of stack source radiologic emissions shall be the responsibility of the
         party which caused such violation.

                  (c) A Radiation Safety Officer from each of the Seller and the
         Buyer Sub will meet not less than annually to mutually review the stack
         source radiological emissions and assure that the agreed controls on
         each side are sufficiently maintained to assure compliance. If such
         Radiation Safety Officers cannot resolve any issues that arise
         regarding such emissions, these issues will be referred to the
         Executive Committee for resolution.

         7.7.     Storm Water Emissions.
                  ---------------------

                  (a) A design has been developed for segregating the stormwater
                  collection systems that will service, respectively, the Owned
                  Real Property and that portion of "Parcel 4" which will be
                  retained by the Seller (the "SEG SITE") after the Closing. The
                  Buyer Sub will pay the Seller $72,000 as payment in full for
                  its share of the costs associated with implementation of this
                  separate stormwater collection system and the related fence
                  and curb. The Seller shall manage the implementation of the
                  new "Stormwater Management Area", and fence and curb
                  installation. The Seller shall also manage and effect the
                  related stormwater system modifications that straddle the curb
                  and are required to separate the systems as defined above. The
                  Seller and the Buyer Sub shall each bear the repair and
                  maintenance costs of the shared curb and fence in the future.
                  To the extent one party's activities have damaged, require
                  alteration or otherwise affect the shared curb or fence, the
                  party responsible shall promptly effect and pay for these
                  changes.

                  (b) The Buyer and the Buyer Sub and the Seller agree that
         storm water runoff from the SEG Site may continue to be discharged
         through the currently established stormwater collection system until
         the fully 
<PAGE>   33
                                      -27-


         segregated system described in paragraph (a) above is implemented. In
         the interim period, the Seller shall conduct all required monitoring of
         storm water discharges from its property and provide the Buyer Sub with
         the results thereof. To the extent possible, the Seller will provide
         the Buyer Sub with at least five (5) days prior written notice before
         conducting any such monitoring in order to allow the Buyer Sub to
         conduct coordinated sampling with the Seller.

                  (c) Until such time that the Seller has established its
         separate storm water collection and retention system and discharge
         point, the Seller and the Buyer Sub each agree to restrict discharges
         through the common outfall such that neither party exceeds 50% of the
         effluent parameters specified in Table 7.1 and paragraphs 7(a), (b) and
         (d) of Rule 1200-4-10-.04, as established under the authority of the
         Tennessee Water Quality Control Act of 1977 (the "STORM WATER RULE").
         Neither party shall exceed the 50% effluent parameter without the prior
         written consent of the other party. The liability for any violation of
         the storm water permit will remain the responsibility of the party
         which caused the violation.

                  (d) In the event of any discharge through the common outfall
         in the interim period that constitutes a non-compliance under the Storm
         Water Rule, the Buyer Sub and the Seller agree to jointly investigate
         the cause or source of such non-compliance. If compliance personnel
         from the Buyer Sub and the Seller cannot resolve any issues related to
         such non-compliance condition, these issues will be referred to the
         Executive Committee for resolution.

                  (e) With respect to the settlement collection basin
         constituting part of the existing stormwater system, the Seller agrees
         to remediate the settlement collection basin, promptly after the
         Closing, so that it is below accepted background levels of 5 picocuries
         per gram of artificial (not naturally occurring) radionuclides. Such
         remediation shall be at the Seller's expense. In addition, promptly
         after the Seller has installed its separate stormwater collection
         system, it will if required remediate the settlement collection basin
         so that it is below accepted background levels of 5 picocuries per gram
         of artificial (not naturally occurring) radionuclides. Such remediation
         shall be shared equally by the Seller and the Buyer Sub.

         7.8. Q-CEP CONTAINER. The Seller confirms that it has completed at its
own expense the South Carolina state approval process for the design of a final
form of Q-CEP container. The Buyer and the Buyer Sub and the Seller will
cooperate with each other to have such approval issued to the Buyer Sub with
respect to the use thereof.

                                      -28-


         7.9.     ARROWSMITH NON-COMPETE. SEG agrees that at the Closing it will
enter into an amendment of its non-competition arrangements with Mr. Arrowsmith
in the form of EXHIBIT L hereto.

         7.10.    EQUIPMENT DISPOSAL. As between the Buyer and the Buyer Sub, on
the one hand, and Westinghouse and the Seller, on the other hand, effective as
of the Closing the Buyer Sub shall be responsible for the ultimate disposal of
all Equipment transferred to the Buyer Sub at the end of such Equipment's useful
life, except as otherwise provided in Section 10.4(b).

         7.11.    Termination of Master Agreement; Release.
                  ----------------------------------------

                  (a) Effective as of the Closing, the Buyer and the Seller
         hereby terminate the Master Agreement pursuant to Section 16.1 thereof.
         Notwithstanding any provision in the Master Agreement to the contrary
         (including, but not limited to, Section 16.6 thereof), no provision of
         the Master Agreement will survive such termination, including, but not
         limited to, the provisions of Articles 1, 3, 6, 7 (including Section
         7.5), 7, 9, 12, 13 (including Section 13.1), 14, 15, 16 (including
         Section 16.7), 17, 19, 20 and 21. No such termination shall affect
         SEG's or MMT's rights with respect to any breach or nonperformance by
         the other party of any Section of the Master Agreement expressly
         excluded from the provisions of paragraphs (b), (c) and (d) below. Any
         such claims shall be subject to and governed by Article 10 of this
         Agreement.

                  (b) Effective as of the Closing, the Seller, the Buyer and, in
         the case of the Westinghouse Agreement, Westinghouse hereby agree to
         terminate the Dispute Resolution Agreement, the Environmental
         Indemnification Agreement, the Westinghouse Agreement and any other
         Related Agreement. Notwithstanding any provision in any Related
         Agreement or the Master Agreement to the contrary, no provision of any
         Related Agreement will survive such termination. No such termination
         shall affect the Buyer's rights with respect to any breach or
         nonperformance by Westinghouse of the Westinghouse Agreement insofar as
         it relates to Article 20 of the Master Agreement. Any such claims shall
         be subject to and governed by Article 10 of this Agreement.

                  (c) Effective as of the Closing, the Buyer hereby releases and
         forever discharges the Seller and Westinghouse and their respective
         Affiliates, officers, directors, agents, employees, successors and
         assigns (collectively, the "SELLER/WEC RELEASEES"), from all actions,
         causes of actions, debts, demands and claims, whether liquidated or
         unliquidated (including, without limitation, costs and expenses) based
         upon, arising under or with respect to the Master Agreement or any
         Related Agreement and the transactions contemplated thereby, whether
         known or unknown, 
<PAGE>   35
                                      -29-

         suspected or claimed, which the Buyer ever had, now has or hereafter
         may claim to have (other than under this Agreement or the agreements to
         be entered into pursuant hereto) against the Seller/WEC Releasees or
         any of them, except for any claim by the Buyer against the Seller or
         Westinghouse for breach or non-performance of any of the provisions of
         Article 14 or 20 of the Master Agreement or the Westinghouse Agreement
         insofar as it relates to Article 20 of the Master Agreement. Any such
         claims shall be subject to and governed by Article 10 of this
         Agreement. The Buyer hereby confirms that as of the date of this
         Agreement it has no actual knowledge (which for purposes of this
         paragraph (c) shall be limited to the actual knowledge of Messrs. Bud
         Arrowsmith, Haney, Gatto, Nagel and Jacks) of any breach by the Seller
         or Westinghouse of the sections of the Master Agreement or Westinghouse
         Agreement referred to above.

                  (d) Effective as of the Closing, the Seller and Westinghouse
         hereby release and forever discharge the Buyer and its Affiliates,
         officers, directors, agents, employees, successors and assigns
         (collectively, the "BUYER RELEASEES"), from all actions, causes of
         actions, debts, demands and claims, whether liquidated or unliquidated
         (including, without limitation, costs and expenses) based upon, arising
         under or with respect to the Master Agreement or any Related Agreement
         and the transactions contemplated thereby, whether known or unknown,
         suspected or claimed, which the Seller or Westinghouse ever had, now
         have or hereafter may claim to have (other than under this Agreement or
         the agreements to be entered into pursuant hereto) against the Buyer
         Releasees or any of them, except for any claim by the Seller or
         Westinghouse for breach or non-performance of any of the provisions of
         Article 14 or 20 of the Master Agreement. Any such claims shall be
         subject to and governed by Article 10 of this Agreement. The Seller
         hereby confirms that as of the date of this Agreement it has no
         knowledge of any breach by the Buyer of the sections of the Master
         Agreement referred to above.

         7.12.    EXECUTIVE COMMITTEE. The Buyer and the Seller shall establish
an executive committee to implement the terms and conditions of this Agreement
(the "EXECUTIVE COMMITTEE") consisting of a single senior representative
designated by the Seller and a single senior representative designated by the
Buyer ("DIRECTORS"). Any Director designated by a party must be reasonably
satisfactory to the other party. The initial Directors are Messrs. Caso and
Gatto. The Executive Committee's initial principal functions will be to oversee
the transition of the Seller's interest in the Q-CEP Plant and the Processing
Activities to the Buyer Sub and to implement the activities contemplated by the
Services Agreement. The Directors shall meet from time to time to discuss any
issues that may have arisen under this Agreement or any of the Agreements
entered into pursuant hereto. During the first year after the Closing the
Executive Committee shall meet no less 
<PAGE>   36
                                      -30-

often than quarterly. Either Director shall have the right to call a meeting to
discuss any outstanding issues.

         7.13.    Acquired Resins; Processing and Storage.
                  ---------------------------------------

                  (a) Attached as SCHEDULE 7.13 is a list of ion exchange resins
         that constitute part of the Acquired Assets (the "ACQUIRED RESINS").
         The Seller has previously accepted the Acquired Resins for processing
         pursuant to contracts with customers and has already invoiced the
         applicable customers for such processing services in the amounts set
         forth on SCHEDULE 7.13 (the "INVOICED PRICES").

                  (b) The Buyer Sub agrees to assume the Seller's obligations to
         process, treat, dispose or otherwise handle the Acquired Resins. In
         doing so, (i) the Buyer Sub shall be free to choose the methods used,
         subject to the Seller's contractual commitments to such customers and
         applicable Laws, and (ii) the Buyer Sub will comply with all of the
         Seller's relevant obligations under the applicable contracts with
         customers and all applicable Laws.

                  (c) In consideration for the Buyer Sub's agreement to assume
         the foregoing obligation to process or otherwise handle the Acquired
         Resins, the Seller agrees to pay to the Buyer Sub the Invoiced Prices.
         To the extent payment has previously been made to SEG, such payment
         will be made at the Closing. With respect to any payment not previously
         made, the Seller shall remit to the Buyer Sub any such payment promptly
         after receipt. Such payment shall constitute payment in full of the
         Buyer Sub for its activities under this Section 7.13.

                  (d) The Seller agrees that, for the first ninety (90) days
         after the Closing, the Seller will permit the Buyer Sub to store the
         Acquired Resins at the Seller's Bear Creek site, so long as such
         storage is allowed under all applicable Laws. At the end of such ninety
         day period the Seller shall convey possession to the Buyer Sub of any
         remaining Acquired Resins at the Bear Creek site, other than those
         Acquired Resins to be processed by the Seller pursuant to the notice
         given by the Buyer Sub pursuant to paragraph (e) below.

                  (e) Within sixty (60) days after the Closing Date the Buyer
         Sub will determine whether it wishes the Seller to provide any
         processing services with respect to any of the Acquired Resins and will
         provide notice to the Seller of such determination, specifying in
         reasonable detail the Acquired Resins to be processed by the Seller. In
         the event the Buyer Sub requests the Seller to perform any processing
         services on behalf of the Buyer Sub with respect to the Acquired
         Resins, the Seller will process the 
<PAGE>   37
                                      -31-


         applicable Acquired Resins if (i) they meet the Seller's "waste
         acceptance criteria" then in effect and (ii) the Seller can process
         such Acquired Resins using commercially reasonable efforts, within the
         time limits, if any, imposed by its applicable permits and contract
         requirements. The Buyer Sub and the Seller will cooperate with respect
         to any such processing so that the Seller is able to process the
         Acquired Resins within the time limits, if any, imposed by its
         applicable permits. As the applicable Acquired Resins are designated by
         the Buyer Sub for processing or other handling by the Seller, the
         Seller will invoice the Buyer Sub in the amount of the applicable
         Invoiced Prices. Payment terms will be net ten (10) days from the date
         of invoice. Such payment shall constitute payment in full of the Seller
         for its processing or handling activities under this Section 7.13.

                  (f) So long as any of the Acquired Resins are located at the
         Bear Creek site the Buyer Sub agrees to indemnify the Seller from and
         against all Losses (as defined in Article 10) arising from the storage
         of the Acquired Resins at the Seller's site, except to the extent that
         any such Losses are caused by Seller's negligence or willful
         misconduct.

         7.14.    GENERAL SIGNAL; QUANTERRA. The Buyer's assumption and
agreement in Section 2 of the General Signal Assignment is intended to be for
the benefit of General Signal Corporation, and is not intended as between the
parties hereto to affect the allocation of responsibilities provided for in the
Agreement, pursuant to which the Seller and Westinghouse are to remain
responsible for all Excluded Liabilities and the Buyer and the Buyer Sub are to
assume and perform all Assumed Liabilities. The Buyer Sub's assumption and
agreement in Section 2 of the Quanterra Assignment is intended to be for the
benefit of Quanterra Incorporated, and is not intended as between the parties
hereto to affect the allocation of responsibilities provided for in the
Quanterra Assignment, pursuant to which the Seller and Westinghouse are to
remain responsible for all Excluded Liabilities and the Buyer and the Buyer Sub
are to assume and perform all Assumed Liabilities.

         7.15.    COPYING OF BOOKS AND RECORDS. In addition to their obligations
under Section 7.3, to the extent not already delivered prior to the Closing the
Seller will deliver copies or originals of the Customer Contracts and related
contract files consistent with Section 5.11(a) and consistent with the terms of
the CC Assignments and the Processing Subcontracts. In addition, representatives
of the Buyer Sub and the Seller will meet promptly after the Closing to ensure
that the Seller has delivered or will deliver promptly copies of all other
material records and documents constituting part of the Acquired Assets. In
addition, with respect to any documents and records constituting part of the
Acquired IP, the Buyer Sub may request that the Seller deliver all copies of
centrally located
<PAGE>   38
                                      -32-

documents and records that constitute part of the Acquired IP but do not
constitute part of the SEG Retained IP or Westinghouse Retained IP.

         7.16.    DISCOUNTS. To the extent that the Seller or Westinghouse has
provided discounts with respect to any Customer Contracts pursuant to any of the
Westinghouse steam generator litigation settlement agreements with a customer,
if the Buyer Sub is required to continue such discount then Westinghouse will
reimburse the Buyer Sub for the amount of such discount, promptly after receipt
of the Buyer Sub's invoice therefor.

         7.17.    DRYER. With respect to the dryer to be used for the Q-CEP
Plant, the Seller agrees to pay the Buyer Sub the amount of $250,000 at Closing
to reimburse the Buyer Sub for anticipated costs of repairing or replacing the
dryer. In addition, the Seller will transfer to the Buyer Sub as part of the
Acquired Assets all rights the Seller has against the manufacturer, Jaygo. In
addition, the Seller agrees that if requested by the Buyer Sub prior to the
first anniversary of the Closing it will dispose of the dryer at no charge to
the Buyer Sub.

         7.18.    Methodology with Respect to Customer Contracts.

                  (a)      The parties hereto acknowledge that, in transferring
         all or part of the Customer Contracts to the Buyer Sub as part of the
         Acquired Assets, their intent and methodology has been as follows:

                           (i)      those Customer Contracts with scopes of work
                  which involve solely Processing Activities are to be assigned
                  to the Buyer Sub in full;

                           (ii)     those Customer Contracts with scopes of work
                  that include, but are not limited to, Processing Activities
                  which have already been definitized and priced, are to be
                  assigned to the Buyer Sub solely to the extent of such
                  definitized and priced Processing Activities;

                           (iii)    those Customer Contracts that are to be
                  partially assigned to the Buyer Sub pursuant to clause (ii)
                  above which also involve scopes of work that include Assumable
                  Services (as defined below), currently not definitized and
                  priced, that may arise in the future, will be subcontracted to
                  the Buyer Sub at its election pursuant to a Processing
                  Subcontract for the nine-month period contemplated by
                  paragraph (b) below;

                           (iv)     with respect to services to be performed
                  with respect to small generators and brokered waste streams,
                  such services will

                                      -33-


                  be performed by the Buyer Sub pursuant to a Processing
                  Subcontract;

                           (v)      any consents required from customers will be
                  addressed by the provisions of Section 7.19;

                           (vi)     with respect to current contracts of the
                  Seller or Westinghouse omitted (inadvertently or otherwise)
                  from SCHEDULES 1.1(b) AND 1.2(b), but which provide for
                  Assumable Services (as defined below), in the event that
                  during the first nine (9) months after the Closing the Seller
                  or Westinghouse is requested or required to perform any
                  activities under any such contract, such services will be
                  performed by the Buyer Sub or the Seller or Westinghouse as
                  provided in paragraph (b) below; in the event any consent from
                  a customer is required for the performance by the Buyer Sub of
                  such Assumable Services pursuant to a Processing Subcontract,
                  the applicable parties will seek such consent and, if not
                  obtained, enter into arrangements of the type contemplated by
                  Section 7.19(d); and

                           (vii)    with respect to all of the Customer 
                  Contracts, the Seller or Westinghouse will retain the economic
                  benefits and burdens relating to performance prior to the
                  Closing, and the Buyer Sub will be transferred and will assume
                  the benefits and burdens relating to the performance of such
                  Customer Contracts after the Closing (subject, in the case of
                  the Customer Contracts referred to in clause (iii) above, to
                  the lapse of the applicable Processing Subcontract).
                  Accordingly, SEG and Westinghouse, as applicable, agree to
                  perform that portion of the Customer Contracts not assigned to
                  Buyer Sub pursuant to CC Assignments or subcontracted to the
                  Buyer Sub pursuant to Subcontracts, that portion of any
                  Non-Transferred Contract for which the Buyer Sub is not to
                  bear the economic benefits and burdens as provided in Section
                  7.19(d) and any Assumable Service that the Buyer Sub elects
                  not to perform pursuant to paragraph (b) below. In addition,
                  the Buyer Sub agrees to perform that portion of the Customer
                  Contracts assigned to the Buyer Sub pursuant to CC Assignments
                  or subcontracted to the Buyer pursuant to Subcontracts, that
                  portion of any Non-Transferred Contract for which the Buyer
                  Sub is to bear the economic benefits and burdens as provided
                  in Section 7.19(d) and any Assumable Services that the Buyer
                  Sub elects to perform pursuant to paragraph (b) below. Without
                  limiting the generality of the foregoing, promptly after the
                  Closing the Seller and the Buyer Sub will make an appropriate
                  adjustment between them to reflect 
<PAGE>   40
                                      -34-


                  services to be performed after the Closing by the Buyer Sub
                  which have been invoiced prior to the Closing by the Seller or
                  Westinghouse.

                  (b) The Seller and Westinghouse agree that, for a period of
         nine (9) months after the Closing, in the event any Person who as of
         the Closing Date is a party to one of the Customer Contracts requests
         either of them to perform services relating to Radioactive Wastes that
         are capable of being performed with the Q-CEP Plant or the Acquired
         Assets and, if Westinghouse is the one requested, such services had
         traditionally been performed by SEG on behalf of Westinghouse (with any
         of such services referred to as "ASSUMABLE SERVICES"), whether or not
         the applicable Customer Contract is still in effect, then the Seller or
         Westinghouse will make the Buyer Sub aware of any Assumable Services
         requested by customers and provide the Buyer Sub the information
         reasonably required by it to make its decision to perform such
         Assumable Services. If the Buyer Sub elects to perform such Assumable
         Services, it will do so pursuant to a Processing Subcontract generally
         in the form of EXHIBIT I-1 hereto, unless it enters into a contract
         directly with the customer, and in either case neither Westinghouse nor
         the Seller shall perform such Assumable Services. If the Buyer Sub
         elects not to perform such Assumable Services, it will notify the
         Seller of such decision promptly, and thereafter the Seller or
         Westinghouse shall be free to perform or have performed such Assumable
         Services, notwithstanding the provisions of Section 9.1. The Executive
         Committee shall meet as required to resolve any issues relating to the
         performance of any such Assumable Services.

         7.19.    Nontransferable Contracts.
                  -------------------------

                  (a) To the extent that any Assumed Contract may not be
         transferred by the Seller or Westinghouse to the Buyer or the Buyer Sub
         pursuant to this Agreement, or a Customer Contract that is the subject
         of a Processing Subcontract may not be subcontracted to the Buyer Sub
         pursuant to this Agreement, without the consent, approval or waiver of
         a third person or entity (including a governmental authority), and such
         consent is not obtained prior to the Closing, or if such transfer or
         attempted transfer would constitute a breach thereof or a violation of
         any law, rule or regulation or permit or license, nothing in this
         Agreement will constitute a transfer or subcontract or an attempted
         transfer or subcontract thereof.

                  (b) Notwithstanding anything contained in this Agreement to
         the contrary, the Seller and Westinghouse will not be obligated to
         transfer to the Buyer or the Buyer Sub any of their rights and
         obligations in and to any of the Assumed Contracts referred to in
         paragraph (a) above or to subcontract any of 
<PAGE>   41
                                      -35-


         the Customer Contracts referred to in paragraph (a) above without first
         having obtained all consents, approvals and waivers necessary for such
         transfers or subcontracts. The Seller and Westinghouse and the Buyer
         and the Buyer Sub will use their commercially reasonable efforts to
         obtain such consents, approvals and waivers and to obtain any other
         consents, approvals and waivers necessary to assign to the Buyer Sub
         any of such Assumed Contracts or to subcontract to the Buyer Sub any of
         such Customer Contracts. Each of the Seller and Westinghouse and the
         Buyer and Buyer Sub shall bear its own expenses incurred in connection
         with such efforts.

                  (c) In the event that any consent, approval or waiver
         necessary to assign to the Buyer or the Buyer Sub any Assumed Contract
         or to subcontract any applicable Customer Contract has not been
         obtained prior to the Closing, then the Seller and Westinghouse and the
         Buyer or the Buyer Sub will each use its reasonable commercial efforts,
         each at its own expense, to (i) provide to the Buyer or the Buyer Sub,
         as applicable, the benefits and burdens of any such Assumed Contract or
         Customer Contract, (ii) cooperate in any reasonable and lawful
         arrangement designed to provide such benefits and burdens to the Buyer
         or the Buyer Sub, as applicable, in accordance with this Agreement,
         without incurring any additional obligation to any other Person,
         including without limitation the appointment of the Buyer or the Buyer
         Sub as the agent of the Seller for purposes of such Assumed Contract
         and (iii) enforce, at the request of the Buyer or the Buyer Sub for the
         account of the Buyer or the Buyer Sub, any rights arising from any such
         Assumed Contract or Customer Contract (including without limitation the
         right to elect to terminate an Assumed Contract in accordance with the
         terms thereof upon the advice of the Buyer or the Buyer Sub).

                  (d) The Seller and Westinghouse and the Buyer Sub agree that,
         with respect to any Assigned Customer Contract of the type referred to
         above in paragraph (c), if a consent to assignment cannot be obtained
         and a consent to subcontract is required from a third person, they will
         solicit such consent. If such a consent to subcontract is obtained with
         respect to any such Assigned Customer Contract, the Seller or
         Westinghouse, as applicable, and the Buyer Sub will enter into a
         subcontract substantially in the form of EXHIBIT M (an "UNASSIGNED
         CONTRACT SUBCONTRACT"), and thereafter the Buyer Sub will complete the
         performance of such Assigned Customer Contract pursuant to such
         Unassigned Contract Subcontract.

                  (e) If the Buyer Sub and the Seller or Westinghouse, as
         applicable, are unable to obtain any required consents to assign or
         subcontract any particular Assigned Customer Contract or to enter into
         any particular Processing Subcontract (with any such Assigned Customer
         Contract or Customer Contract for which the parties had intended to
         enter into a 
<PAGE>   42
                                      -36-


         Processing Subcontract referred to herein as an "NON-TRANSFERRED
         CONTRACT"), and the Seller or Westinghouse, as applicable, and the
         Buyer Sub agree that no such consent will be obtained, and no other
         mutually satisfactory arrangements are agreed to, then (i) such
         Non-Transferred Contract shall be deemed not to have been transferred
         or subcontracted to the Buyer Sub, and (ii) the Seller or Westinghouse,
         as applicable and the Buyer Sub shall treat such Non-Transferred
         Contract as if the Seller or Westinghouse, as applicable, and the Buyer
         Sub had entered into a seconding arrangement with respect to the
         personnel and equipment performing such Non-Transferred Contract as of
         the Closing Date. Such seconding agreement shall be in a mutually
         acceptable form and shall be structured similar to the arrangements
         described in clauses (i)-(iii) of the first sentence of paragraph (c)
         above, with the effect that the Buyer Sub bears economic responsibility
         for all profits and losses for the applicable transferred scope of such
         Non-Transferred Contract and all liabilities arising after the Closing
         with respect to the performance of the applicable transferred scope of
         such Non-Transferred Contract.

                  (f) No consent, approval or waiver of a third person or entity
         (including a governmental authority) with respect to the transfer of,
         or any novation with respect to, any Assumed Contract or Processing
         Subcontract shall cause an Excluded Liability to be deemed for purposes
         of this Agreement to have become an Assumed Liability or vice-versa or
         otherwise affect the respective rights of the parties to this Agreement
         under Article 10.

         8.1. Confidentiality Obligations of the Buyer
              ----------------------------------------

                  (a) The Buyer and the Buyer Sub agree that they will use SEG
         Confidential Information only in connection with the Q-CEP Plant and
         the Processing Activities or as otherwise contemplated by this
         Agreement or any Acquisition Agreement, and they will not disclose any
         SEG Confidential Information to any Person except as expressly
         permitted by this Section 8.1. The foregoing restriction shall not
         apply to the disclosure or use of information which: (i) the Buyer or
         the Buyer Sub can show was previously known to it prior to receipt from
         the Seller; (ii) the Buyer or the Buyer Sub can show was developed by
         employees or agents of the Buyer or the Buyer Sub independently of and
         without reference to any SEG Confidential Information; (iii) is now, or
         hereafter becomes, widely known or widely available in the radioactive
         waste industry through no wrongful act of the Buyer or the Buyer Sub;
         or (iv) is subsequently disclosed to the 

<PAGE>   43
                                      -37-


         Buyer or the Buyer Sub by a third party not owing an obligation of
         confidence to the Seller or Westinghouse.

                  (b)      The Buyer and the Buyer Sub may disclose SEG 
         Confidential Information:

                           (i)      to the Buyer's directors, officers,
                  employees and representatives (including outside legal
                  counsel, accountants and other professionals) who have a
                  reasonable need to know the contents thereof and who are
                  subject to a written confidentiality agreement with the Buyer
                  or the Buyer Sub obligating them to keep confidential the SEG
                  Confidential Information, subject to customary exceptions
                  similar to those set forth in paragraphs (a) above and (b)(ii)
                  below; and

                           (ii)     to the extent required by applicable
                  statute, rule or regulation or any court of competent
                  jurisdiction; PROVIDED that the Buyer or the Buyer Sub has
                  made reasonable efforts to conduct its relevant business
                  activities in a manner such that the disclosure requirements
                  of such statute, rule or regulation or court of competent
                  jurisdiction do not apply, and PROVIDED FURTHER that the
                  Seller is given notice and an adequate opportunity to contest
                  such disclosure or to use any means available to minimize such
                  disclosure (E.G., the "confidential treatment" provisions of
                  Rule 24b-2 promulgated under the Securities Exchange Act of
                  1934, as amended).

         8.2. Confidentiality Obligations of the Seller and Westinghouse.
              ----------------------------------------------------------

                  (a)      Each of the Seller and Westinghouse agrees that it 
         will use MMT Confidential Information only in connection with the
         activities contemplated by this Agreement or any Acquisition Agreement,
         and it will not disclose any MMT Confidential Information except as
         expressly permitted by this Section 8.2. The foregoing restriction
         shall not apply to the disclosure or use of information which: (i) the
         Seller or Westinghouse can show was previously known to it prior to
         receipt from the Buyer or the Buyer Sub; (ii) the Seller or
         Westinghouse can show was developed by its or their respective
         employees or agents independently of and without reference to any MMT
         Confidential Information; (iii) is now, or hereafter becomes, widely
         known or widely available in the radioactive waste industry through no
         wrongful act of the Seller or Westinghouse; or (iv) is subsequently
         disclosed to the Seller or Westinghouse by a third party not owing an
         obligation of confidence to the Buyer or the Buyer Sub.

<PAGE>   44
                                      -38-


                  (b)      The Seller and Westinghouse may disclose MMT 
         Confidential Information:

                           (i)      to its directors, officers, employees and
                  representatives (including outside legal counsel, accountants
                  and other professionals) who have a reasonable need to know
                  the contents thereof and who are subject to a written
                  confidentiality agreement with the Seller or Westinghouse, as
                  applicable, obligating them to keep confidential the MMT
                  Confidential Information, subject to customary exceptions
                  similar to those set forth in paragraphs (a) above and (b)(ii)
                  below; and

                           (ii)     to the extent required by applicable
                  statute, rule or regulation or any court of competent
                  jurisdiction; PROVIDED that the Seller or Westinghouse has
                  made reasonable efforts to conduct its relevant business
                  activities in a manner such that the disclosure requirements
                  of such statute, rule or regulation or court of competent
                  jurisdiction do not apply, and PROVIDED further that the
                  Buyer or the Buyer Sub is given notice and an adequate
                  opportunity to contest such disclosure or to use any means
                  available to minimize such disclosure (E.G., the
                  "confidential treatment" provisions of Rule 24b-2     
                  promulgated under the Securities Exchange Act of 1934, as
                  amended).

         8.3. THIRD PARTY INFORMATION. The Buyer, the Buyer Sub, Westinghouse
and the Seller agree that nothing in this Agreement or any agreement entered
into pursuant hereto shall be deemed to obligate any of them to disclose SEG
Confidential Information or MMT Confidential Information in violation of a
confidentiality obligation owed by the party possessing such information. In the
event that the Seller or Westinghouse discloses SEG Confidential Information to
the Buyer or the Buyer Sub, or the Buyer or the Buyer Sub discloses MMT
Confidential Information to the Seller or Westinghouse, in violation of a
confidentiality obligation owed to a third party by the disclosing party, the
recipient shall, without limiting its other obligations under this Article 8,
upon request return to the disclosing party all copies of such confidential
information in any tangible form.

         8.4. LIMITATIONS ON OBLIGATIONS. The restrictions set forth in Section
8.1(a) and Section 8.2(a) shall apply to SEG Confidential Information or MMT
Confidential Information, as applicable, only to the extent such confidential or
proprietary information (i) if first disclosed in tangible form, is marked as
"Proprietary" or "Confidential" or (ii) if first disclosed in verbal, visual or
other intangible form, at the time of disclosure was identified or referred to
as confidential or proprietary and is within sixty (60) days after such
disclosure 
<PAGE>   45
                                      -39-

embodied or described in a tangible form, marked "Confidential" or
"Proprietary", furnished by the disclosing party to the receiving party.

         8.5. CONFIDENTIAL TREATMENT OF CERTAIN ACQUISITION AGREEMENTS. The
parties hereto agree to treat the terms of the Services Agreement and the
exhibits to the CC Assignments and Processing Subcontracts as MMT Confidential
Information and SEG Confidential Information. However, Westinghouse and the
Seller may disclose the terms of the Services Agreement and the exhibits to the
CC Assignments and Processing Subcontracts to prospective purchasers of the
Seller provided such parties have entered into a written confidentiality
agreement, in customary form and of which the Buyer and the Buyer Sub are
intended beneficiaries, obligating them to keep the terms of the Acquisition
Agreements confidential.

         PERIOD"), it shall not anywhere in the world either directly or
         indirectly (whether through its Affiliates, as a shareholder, partner
         or consultant or otherwise) promote, market, sell, license, own,
         operate, finance or otherwise commercialize or engage in, or solicit or
         negotiate to engage in, any business to volume reduce, recycle or
         otherwise treat or process IER Feedstocks, including without limitation
         any processing using gasification, plasma, vitrification, incineration,
         metal melting, CEP or any similar or comparable technologies; PROVIDED
         THAT the provisions of this paragraph (a) shall not restrict the Seller
         or Westinghouse, directly or indirectly, from engaging, soliciting or
         negotiating to engage in the handling or other preprocessing of IER
         Feedstocks in anticipation of, but not to include, their burial,
         destruction, recycling or other final processing. Without limiting
         their obligations under Section 9.2, nothing in this paragraph (a)
         shall prohibit Westinghouse or the Seller from retaining any third
         party to provide any of the services referred to in this paragraph (a)
         if such activities are provided ancillary to other services provided by
         Westinghouse or the Seller, as applicable.

                  (b) The Seller agrees that during the Restricted Period it
         shall not, at any operating commercial nuclear power plant anywhere in
         the world, engage, either directly or indirectly (whether through its
         Affiliates, as a shareholder, partner or consultant or otherwise), in
         (i) the removal of water from Radioactive Waste accomplished primarily
         by physical means, 
<PAGE>   46
                                      -40-


         for disposal without further treatment or processing of such
         Radioactive Waste or (ii) solidification of Radioactive Waste with a
         cement binder in preparation for disposal without further treatment or
         processing of such Radioactive Waste (the "SPECIFIED RESTRICTED
         PROCESSES"); PROVIDED THAT the provisions of this paragraph (b) shall
         not restrict the Seller, directly or indirectly, from (x) engaging in
         any treatment of Radioactive Waste performed before the Radioactive
         Waste is further treated in any process, other than the Specified
         Restricted Processes, which the Seller provides or will provide in the
         future, (y) processing any Secondary Waste of the Seller or (z) either
         the removal of water from Radioactive Waste or solidification of
         Radioactive Waste with a cement binder, provided that the amount of
         Radioactive Waste processed at the request of any customer pursuant to
         this clause (z) is DE MINIMIS (i.e., not more than the equivalent of
         two 55-gallon drums over the life of the applicable contract), and such
         services are provided ancillary to other services provided by the
         Seller to the same customer. This paragraph (b) is not intended to
         apply to activities of Westinghouse or its Affiliates (other than the
         Seller or its Subsidiaries) unless Westinghouse or such Affiliates are
         performing such activities on behalf of the Seller.

                  (c) The activities prohibited by paragraph (a) above are
         referred to herein as a "FIRST COMPETING ACTIVITY", the activities
         prohibited by paragraph (b) above are referred to herein as a "SECOND
         COMPETING ACTIVITY" and they are collectively referred to herein as the
         "COMPETING ACTIVITIES".

                  (d) The restrictions set forth in paragraphs (a) and (b) above
         shall not restrict the Seller, Westinghouse or any of their respective
         Affiliates from performing their respective obligations pursuant to
         contracts with the United States of America or any agency thereof or
         any other domestic or foreign government or government agency or
         pursuant to any subcontracts, supply contracts or other similar
         contracts or other agreements entered into in connection with or under
         any such governmental contracts, subject to their respective
         obligations under Section 9.2. In addition, the restrictions set forth
         in paragraphs (a) and (b) above shall not prohibit the Seller or
         Westinghouse or any of their respective Affiliates from owning,
         directly or indirectly, less than five percent (5%) of any class of
         securities listed on a national securities exchange or traded publicly
         in the over-the-counter market of any corporation engaged in any
         Competing Activity. In addition, the restrictions set forth in
         paragraphs (a) and (b) above shall not prohibit the Seller or
         Westinghouse from performing their obligations under any Subcontract,
         or from entering into the arrangements contemplated by Section 7.19(d)
         with respect to any Non-Transferred Contract or, during the first nine
         months after the Closing, from performing 
<PAGE>   47
                                      -41-


         any of the Assumable Services that the Buyer Sub elects not to perform
         pursuant to Section 7.18(a)(vi) or (b).

                  (e) It is recognized by the parties hereto that damages for
         breaches of covenants of the nature contained in this Section 9.1 are
         difficult if not impossible precisely to prove; therefore, it is agreed
         that this Section 9.1 shall be enforceable by mandatory injunction, in
         addition to any other remedy available to the Buyer or the Buyer Sub
         under this Agreement or at law or equity. If any of the restrictions
         contained in this Section 9.1 shall be deemed to be unenforceable by
         reason of the extent, duration or geographical scope or other provision
         hereof, then the parties hereto contemplate that the court shall reduce
         such extent, duration, geographical scope or other provision hereof and
         enforce this Section 9.1 in its reduced form for all purposes in the
         manner contemplated hereby.

                  (f) If during the Restricted Period the Seller transfers or
         agrees to transfer any substantial portion of its assets to any third
         party or Westinghouse transfers or agrees to transfer (by sale, merger
         or otherwise) all or substantially all of the Seller's capital stock to
         any third party, as a condition precedent to such transfer Westinghouse
         and the Seller shall cause the transferee to agree in writing with the
         Buyer and the Buyer Sub to comply with the Seller's obligations under
         Section 9.1(a) and Section 9.2 for the remainder of the Restricted
         Period. However, in the event Westinghouse sells the capital stock of
         the Seller or the Seller sells all or substantially all of its assets
         to a third party (the "SEG SUCCESSOR"), during the remainder of the
         Restricted Period the geographic scope of the non-competition
         obligation set forth in paragraph (a) above for the SEG Successor (and,
         in the event of a stock transfer or merger in which the Seller
         survives, the Seller) will be reduced to North America and the SEG
         Successor will not be required to divest or shut down any existing
         operations in North America; PROVIDED, HOWEVER, that any expansion of
         any First Competing Activity (which for purposes hereof shall mean
         either (x) any increase in total design capacity for processing of IER
         Feedstocks or (y) any increase in the design radiation level of the IER
         Feedstocks to be processed) by the Seller or the SEG Successor would be
         subject to the non-competition obligation set forth in paragraph (a)
         above. Any SEG Successor would not be subject to the non-competition
         obligation set forth in paragraph (b) above.

                  (g) If during the Restricted Period Westinghouse agrees to
         transfer any substantial portion of its assets to any third party or
         any third party agrees to acquire (by sale, merger or otherwise) all or
         substantially all of Westinghouse's capital stock, as a condition
         precedent to such transfer Westinghouse shall cause the transferee to
         agree in writing with the Buyer 
<PAGE>   48
                                      -42-


         to comply with the restrictions applicable to Westinghouse under
         Section 9.1(a) and Section 9.2 for the remainder of the Restricted
         Period. Without limiting the generality of the foregoing, if during the
         Restricted Period Westinghouse intends to distribute to its
         stockholders in a "spin-off" transaction (a "SPIN-OFF TRANSACTION") any
         material portion of its businesses (whether or not the businesses to be
         distributed then include SEG), then as a condition precedent to such
         distribution Westinghouse shall cause the Person whose securities are
         distributed to stockholders in such Spin-Off Transaction to agree in
         writing with the Buyer and the Buyer Sub to comply with the
         restrictions applicable to Westinghouse under Section 9.1(a) and
         Section 9.2 for the remainder of the Restricted Period. In the event
         that any third party acquires all of Westinghouse's capital stock
         without entering into any agreement with Westinghouse, such third party
         shall be deemed to have acquired such capital stock subject to the
         restrictions applicable to Westinghouse under Section 9.1(a) and
         Section 9.2 for the remainder of the Restricted Period. However, in the
         event Westinghouse sells all or substantially all of its assets to a
         third party or any third party acquires (by sale, merger or otherwise)
         all or substantially all of the capital stock of Westinghouse (the "WEC
         SUCCESSOR"), the geographic scope of the non-competition obligation set
         forth in paragraph (a) above for the WEC Successor (and, in the event
         of a stock transfer or merger in which Westinghouse survives,
         Westinghouse) will be reduced to North America, and the WEC Successor
         will not be required to divest or shut down any existing operations;
         PROVIDED, HOWEVER, any expansion of any First Competing Activity (which
         for purposes hereof shall mean either (x) any increase in total design
         capacity for processing of IER Feedstocks or (y) any increase in the
         design radiation level of the IER Feedstocks to be processed) by
         Westinghouse or the WEC Successor would be subject to the
         non-competition obligation set forth in paragraph (a) above.

         9.2.  Non-advocacy; Preferred Provider.
               --------------------------------

                  (a) During the Restricted Period Westinghouse will not
         directly or indirectly advocate the use of any technology (other than
         Q-CEP) in any First Competing Activity. Any ancillary services
         subcontracted to third parties pursuant to the last sentence of Section
         9.1(a) will not be considered a violation of this paragraph (a).

                  (b) For a period of three years after the Closing Date, the
         Seller and Westinghouse shall use the Buyer and the Buyer Sub as their
         preferred provider for the treatment or processing of IER Feedstocks.
         As the preferred provider, the Buyer and the Buyer Sub will have the
         right to process and dispose of all IER Feedstocks generated or
         collected by the 
<PAGE>   49
                                      -43-


         Seller or Westinghouse, so long as the fees of the Buyer and the Buyer
         Sub for these services are (i) less expensive than the cost for final
         disposal, including burial of primary and Secondary Waste, without any
         volume reduction, and (ii) no more than 25% greater than the fees of
         the least expensive alternative provider based on such provider's
         published price lists and similar volumes, and the applicable customer
         does not refuse to permit the Buyer or the Buyer Sub to process such
         IER Feedstocks, unless the customer's consent is required under the
         terms of the applicable contract for the Buyer or the Buyer Sub to
         perform such services and the customer does not provide such consent.

                  (c) For a period of three years after the Closing Date, in the
         event that the Buyer or the Buyer Sub elects for any reason to have any
         third party process any IER Feedstocks, the Buyer and the Buyer Sub
         shall use the Seller as its preferred provider for the treatment or
         processing of IER Feedstocks, in which event as to such IER Feedstocks
         the restrictions set forth in Section 9.1(a) shall not apply. As the
         preferred provider, the Seller will have the right to process and
         dispose of all IER Feedstocks generated or collected by the Buyer or
         the Buyer Sub, so long as the Seller's fees for these services are (i)
         less expensive than the cost for final disposal, including burial of
         primary and Secondary Waste, without any volume reduction, and (ii) no
         more than 25% greater than the fees of the least expensive alternative
         provider based on such provider's published price lists and similar
         volumes and the applicable customer does not refuse to permit the
         Seller to process such IER Feedstocks, unless the customer's consent is
         required under the terms of the applicable contract for the Seller to
         perform such services and the customer does not provide such consent.

                           (ii)     an Agency Action directed to, or any other
                  claim of a third party arising out of, a Release or Threat of
                  a Release of a Hazardous Substance or Radioactive Substance
                  caused by Buyer or its agents at, on, or under the Owned Real
                  Property or the Gallaher Facility, at or before the Closing,
                  and, with respect to the Owned Real Property, between the
                  Closing and the time the Owned Real Property is conveyed to
                  the Buyer Sub pursuant to Section 4.2(a).

                  (c)      CONTROL AND PARTICIPATION. With respect to matters
         indemnified pursuant to this Section 10.3 and relating to an Agency
         Action, the party obligated to provide indemnification hereunder (the
         "INDEMNIFYING PARTY") upon accepting its responsibility and liability
         therefor, shall have full control in dealing and negotiating with the
         cognizant regulatory authorities in order to settle all matters giving
         rise to 
<PAGE>   53
                                      -47-


         the Loss; PROVIDED, HOWEVER, that (i) the party entitled to
         indemnification hereunder (the "INDEMNIFIED PARTY") shall have the
         right to attend, at its own expense, any meetings with the regulatory
         authorities and to receive, upon request, copies of all correspondence,
         reports, or other documents submitted or received by or on behalf of
         the Indemnifying Party, and (ii) the Indemnifying Party shall not,
         without the prior written consent of the Indemnified Party (which shall
         not be unreasonably withheld), take any measure or step that imposes
         any unreasonable burden or encumbrance upon the conduct of the
         Indemnified Party's operations.

                  Where Remedial Action is required pursuant to this Section
         10.3, the Indemnifying Party shall have the opportunity to perform such
         Remedial Action, and the Indemnified Party agrees that it shall grant
         or exercise reasonable efforts to cause to be granted to the
         Indemnifying Party a right of reasonable access to the affected real
         property and agrees that it will exercise reasonable efforts to obtain
         a similar right of access to any leased real property from the
         Indemnified Party's tenants, for the purpose of undertaking such
         Remedial Action; PROVIDED, HOWEVER, that such Remedial Action shall be
         conducted in a manner so as to assure no reasonable interference with
         ongoing operations. In addition, all Remedial Actions conducted by the
         Indemnifying Party shall be conducted in compliance with all applicable
         Laws (including Environmental Laws) and in a manner so as not to
         violate any of the Indemnified Party's licenses and permits.

         10.4.  Time Limitations.
                ----------------

                  (a) Neither the Seller and Westinghouse nor the Buyer and the
         Buyer Sub shall be liable to the other under this Article 10 for any
         claim relating to a breach of any representation or warranty referred
         to in Section 10.1(a), Section 10.2(a) or Section 10.3(a)(v) unless,
         (i) in the case of any claim arising under any of Sections 5.4, 5.5,
         5.6, 5.10, 5.11, 5.12, 5.13, 5.14, 5.15 or 5.16 or Section 6.4 (each a
         "SPECIFIED MISREPRESENTATION CLAIM"), the claim is asserted in writing
         by the party seeking indemnification hereunder no later than March 31,
         1998, (ii) in the case of any claim arising under Section 10.1(b)(i) (a
         "TAX CLAIM"), not later than three (3) months after the expiration of
         the applicable statute of limitations with respect to the tax matter to
         which the Tax Claim relates, as such limitation period may be extended
         from time to time, and (iii) in the case of any claim arising under
         Section 10.3(a)(v), the claim is asserted in writing by the party
         seeking indemnification hereunder within ten (10) years after the
         Closing Date. Except as provided in paragraph (b) below, any (x) claim
         for indemnification arising under Section 10.1 or Section 10.2 other
         than a Specified Misrepresentation Claim or a Tax Claim may be made at
         any 
<PAGE>   54
                                      -48-


         time in the future, subject to any applicable statute of limitations,
         and (y) any claim for indemnification under Section 10.3 may be made no
         later than the tenth anniversary of the Closing Date.

                  (b) With respect to any claim for indemnification for a breach
         of the representations and warranties set forth in Section 5.9, any
         claim for indemnification must be made by the close of business on
         December 24, 1996, except as provided in Section 7.17 with respect to
         the Seller's obligations to dispose of the Jaygo dryer. Except as
         provided in Section 7.17, the Buyer Sub's sole remedy for such a claim
         shall be to return the applicable Equipment to the Seller, and the
         Seller shall be obligated to accept such Equipment. The Buyer Sub's
         sole remedy under Section 5.9 as it relates to the Jaygo drier is set
         forth in Section 7.17.

         10.5.  Materiality Standards; Dollar Thresholds.
                ----------------------------------------

                  (a) For purposes of determining those Losses arising from
         breaches of representations, warranties or covenants that will be
         considered immaterial in nature and accordingly not subject to
         indemnification hereunder, the Buyer, the Buyer Sub, the Seller and
         Westinghouse have agreed to use predictable dollar thresholds as
         provided in this paragraph (a). Accordingly, the Buyer, the Buyer Sub,
         Westinghouse and the Seller agree that with respect to any
         representation, warranty or covenant referred to in Section 10.1(a) or
         10.2(a), if such representation, warranty or covenant contains a
         materiality qualification (E.G., "material," "materially," "material to
         the Q-CEP Plant or the Processing Activities," "in all material
         respects," or similar qualifiers), such materiality qualification shall
         be deemed to have been met, and such representation, warranty or
         covenant shall be deemed to have been breached, if the Buyer and the
         Buyer Sub or the Seller and Westinghouse, as applicable, incurs or is
         alleged to have incurred Losses in excess of $25,000 in connection with
         the matter or event to which such representation, warranty or covenant
         relates.

                  (b) Neither the Seller and Westinghouse nor the Buyer and the
         Buyer Sub shall be liable to the other for any Specified
         Misrepresentation Claim or any claim under Section 10.3, including any
         claim relating to Section 5.8 (an "ENVIRONMENTAL CLAIM"), if the total
         Losses with respect to such Specified Misrepresentation Claim or such
         Environmental Claim do not exceed $25,000 ("MINOR CLAIMS").

                  (c) The Seller and Westinghouse shall not be liable to the
         Buyer and the Buyer Sub for any Specified Misrepresentation Claims or
         Environmental Claims unless and until the total Losses suffered by the
         Buyer and the Buyer Sub with respect to all Specified Misrepresentation
         Claims and Environmental Claims exceeds $300,000, excluding Losses 
<PAGE>   55
                                      -49-


         with respect to Minor Claims, and then only to the extent of such
         excess. The Buyer and the Buyer Sub shall not be liable to the Seller
         and Westinghouse for any Specified Misrepresentation Claims or
         Environmental Claims unless and until the total Losses suffered by the
         Seller and Westinghouse with respect to all Specified Misrepresentation
         Claims and Environmental Claims exceeds $300,000, excluding Losses with
         respect to Minor Claims, and then only to the extent of such excess.

                  (d)      The total amount payable by the Seller and 
         Westinghouse under Section 10.1(a) with respect to all Specified
         Misrepresentation Claims shall be the Purchase Price. The total amount
         payable by the Buyer and the Buyer Sub under Section 10.2(a) with
         respect to all Specified Misrepresentation Claims shall be the Purchase
         Price.

                  (e)      No claim for indemnification under Section 10.1 or
         Section 10.2 or Section 10.3, other than a Specified Misrepresentation
         Claim or, as provided in paragraph (c) with respect to Environmental
         Claims, an Environmental Claim, shall be subject to any threshold
         amount or deductible amount or cap on liability. Without limiting the
         generality of the foregoing, no Environmental Claim will be subject to
         a cap on liability.

         10.6.  Claims.
                ------

                  (a)      Any party seeking indemnification hereunder (the
         "INDEMNIFIED PARTY") shall promptly notify the other party hereto
         obligated to provide indemnification hereunder (the "INDEMNIFYING
         PARTY") of any action, suit, proceeding, demand or breach (a "CLAIM")
         with respect to which the Indemnified Party claims indemnification
         hereunder, PROVIDED that failure of the Indemnified Party to give such
         notice shall not relieve any Indemnifying Party of its obligations
         under this Article 10 except to the extent, if at all, that such
         Indemnifying Party shall have been prejudiced thereby. If such Claim
         relates to any action, suit, proceeding or demand instituted against
         the Indemnified Party by a third party (a "THIRD PARTY CLAIM"), upon
         receipt of such notice from the Indemnified Party, the Indemnifying
         Party shall be entitled to participate in the defense of such Third
         Party Claim, and if and only if each of the following conditions is
         satisfied, the Indemnifying Party may assume the defense of such Third
         Party Claim, and in the case of such an assumption the Indemnifying
         Party shall have the authority to negotiate, compromise and settle such
         Third Party Claim:

                           (i)      the Indemnifying  Party confirms in writing
                  that it is obligated hereunder to indemnify the Indemnified
                  Party with respect to such Third Party Claim;

<PAGE>   56
                                      -50-


                           (ii)     the Indemnified Party does not give the
                  Indemnifying Party written notice that it has determined, in
                  the exercise of its reasonable discretion, that matters of
                  corporate or management policy or a conflict of interest make
                  separate representation by the Indemnified Party's own counsel
                  advisable; and

                           (iii)    the Indemnifying Party establishes to the
                  reasonable satisfaction of the Indemnified Party that the
                  Indemnifying Party has (and will continue to have) adequate
                  financial resources to satisfy and discharge such action or
                  claim.

                  The Indemnified Party shall retain the right to employ its own
         counsel and to participate in the defense of any Third Party Claim, the
         defense of which has been assumed by the Indemnifying Party pursuant
         hereto, but the Indemnified Party shall bear and shall be solely
         responsible for its own costs and expenses in connection with such
         participation.

                  (b)      Notwithstanding the foregoing provisions of this
         Section 10.6, (i) no Indemnifying Party shall be entitled to settle any
         Third Party Claim without the Indemnified Party's prior written consent
         unless as part of such settlement the Indemnified Party is released in
         writing from all liability with respect to such Third Party Claim and
         (ii) no Indemnified Party shall be entitled to settle any Third Party
         Claim without the Indemnifying Party's prior written consent unless as
         part of such settlement the Indemnifying Party is released in writing
         from all liability with respect to such Third Party Claim.

                  (c)      In the event one party hereunder should have a claim
         for indemnification that does not involve a Third-Party Claim, the
         party seeking indemnification shall promptly send notice of such Claim
         to the other party.

         10.7. METHOD AND MANNER OF PAYING CLAIMS; SET-OFF. Subject to the
Indemnifying Party's right pursuant to Section 10.6 to defend, negotiate,
compromise and settle a Third Party Claim, the amount of any Claim shall be paid
by the Indemnifying Party forthwith on demand. Any amounts owed or amounts in
dispute by the Seller or Westinghouse to the Buyer or the Buyer Sub or one of
their Affiliates (whether under this Agreement or otherwise) may be set off in
satisfaction of amounts owed or amounts in dispute by the Buyer and the Buyer
Sub or one of their Affiliates to the Seller or Westinghouse or one of their
Affiliates (whether under this Agreement or otherwise) and vice versa.

         10.8. STRADDLE CLAIMS. With respect to the indemnification obligations
of the Seller, Westinghouse, the Buyer and the Buyer Sub under this Article 10,
to the extent that any matter, event or occurrence exists both before and after
the 
<PAGE>   57
                                      -51-


Closing Date, such that the Buyer and the Buyer Sub, on the one hand, and the
Seller and Westinghouse, on the other hand, could both be entitled to
indemnification with respect thereto (such as an ongoing OSHA violation with
respect to which the Seller and the Buyer Sub are assessed a fine attributable
to both pre-Closing and post-Closing periods), the respective indemnification
obligations of the Buyer and the Buyer Sub, on the one hand, and the Seller and
Westinghouse, on the other hand, shall be equitably apportioned between the
Buyer and the Buyer Sub, on the one hand, and the Seller and Westinghouse, on
the other hand, based on respective lengths of time, comparative opportunity to
correct or prevent such matter or occurrence, whether or not the underlying
matter or occurrence also gives rise to a breach of any of the representations
and warranties made by any party to this Agreement or other equitable factors.

         10.9.  Insurance Proceeds.
                ------------------

                  (a) Except as provided in Section 8.4 of the Services
         Agreement, no Indemnified Party shall be obligated to pursue or collect
         from any insurer prior to making a claim for indemnification pursuant
         to this Article 10 and no Indemnifying Party shall be entitled to
         postpone performance of any indemnification obligation under this
         Article 10 while an insurance claim is pending. However, without
         limiting any of the provisions of Sections 10.1 through 10.11 in
         connection with any matter subject to indemnification under this
         Article 10, all parties shall cooperate with each other in giving
         notice of any claim to any insurer (including an insurer of an
         Indemnified Party) and shall provide reasonable assistance in the
         collection of any such claim; PROVIDED, HOWEVER, that there is no duty
         to provide notice, cooperate or assist with respect to an Indemnified
         Party's insurance policies where the Indemnified Party determines in
         its sole discretion that such notice, cooperation or assistance could
         invalidate any portion of the coverage available under such policy or
         result in the imposition of retroactive premiums or prospective premium
         increases. In addition, if an Indemnified Party makes such a
         determination after it has notified its insurer, it shall be entitled
         to retract such notice.

                  (b) If an Indemnified Party actually receives insurance
         proceeds, the amount for which such Indemnified Party is entitled to
         indemnification under this Article 10 shall be reduced appropriately.
         In the event an Indemnified Party receives insurance proceeds after
         being paid by the Indemnifying Party with respect to an indemnifiable
         matter under this Article 10, the Indemnified Party will remit such
         proceeds to the Indemnifying Party, up to the amount previously paid by
         the Indemnifying Party with respect to such matter. Nothing in this
         Section 10.9 shall be deemed to waive or limit the subrogation rights
         of any insurer.

                                      -52-


         10.10    SCOPE OF THIS ARTICLE 10. The parties hereto agree that,
except for injunctive relief, including specific performance, its and their sole
and exclusive remedy with respect to any and all claims relating to the subject
matter of this Agreement shall be subject to this Article 10, except that any
claims relating to the Services Agreement shall be governed by the Services
Agreement.

         10.11    Exclusion of Certain Claims.
                  ---------------------------

                  (a) Except for any deductible amount under the nuclear all
         risk property damage policy maintained by Buyer, the Buyer Sub or any
         of their Affiliates for the Owned Real Property and the personalty
         located thereon that does not exceed two and one-half million dollars
         ($2,500,000), the Seller and Westinghouse shall not be liable to the
         Buyer, the Buyer Sub or any of their Affiliates, whether in contract,
         in tort (including negligence or strict liability) or otherwise, for
         losses or damages to property at or on the Owned Real Property arising
         out of or resulting from any Release by Seller or its Affiliates or
         agents due to or caused by radioactive contamination on, from or out of
         the SEG Site or the Seller's other real property located on Bear Creek
         Road (collectively, the "SELLER'S SITES") provided that such
         radioactive contamination is the result of a covered cause of loss
         under the nuclear all risk property damage policy maintained by Buyer,
         the Buyer Sub or any of their Affiliates for the Owned Real Property
         and the personalty located thereon. The foregoing is based on the
         Buyer's and Buyer Sub's sublimit as of the Closing Date of $15 million
         of liability for radiation cross-contamination under the
         above-referenced nuclear all risk property damage policy. In the event
         this sublimit is reduced by the insurer prior to the third anniversary
         of the Closing Date as a result of any act or omission of the Seller or
         its Affiliates, the exclusion of liability set forth above in this
         paragraph (a) shall not extend to any loss or damage to the extent of
         the difference between the current $15 million radiation
         cross-contamination sublimit and such new reduced sublimit, but in no
         event shall such exception to the liability exclusion of this paragraph
         (a) exceed $7,500,000. The Buyer and the Buyer Sub agree to use
         commercially reasonable efforts to give the Seller and Westinghouse as
         much prior notice as is practicable of any such reduction in sublimits.

                  (b) Except for any deductible amount under the nuclear all
         risk property damage policy maintained by Seller or any of its
         Affiliates for the Seller Sites and the personalty located thereon that
         does not exceed one million dollars ($1,000,000), the Buyer and the
         Buyer Sub shall not be liable to the Seller, Westinghouse or any of
         their Affiliates, whether in contract, in tort (including negligence or
         strict liability) or otherwise, for losses or damages to property at or
         on the Seller Sites arising out of or resulting from any Release by
         Buyer, the Buyer Sub or their Affiliates or 
<PAGE>   59
                                      -53-

         agents due to or caused by radioactive contamination on, from or out of
         the Owned Real Property provided that such radioactive contamination is
         the result of a covered cause of loss under the nuclear all risk
         property damage policy maintained by Seller or any of its Affiliates
         for the Seller's Sites and the personalty located thereon. The
         foregoing is based on the Seller's sublimit as of the Closing Date of
         $35 million of liability for radiation cross-contamination under the
         above-referenced nuclear all risk property damage policy. In the event
         this sublimit is reduced by the insurer prior to the third anniversary
         of the Closing Date as a result of any act or omission of the Buyer,
         Buyer Sub or their Affiliates, the exclusion of liability set forth
         above in this paragraph (b) shall not extend to any loss or damage to
         the extent of the difference between the current $35 million radiation
         cross-contamination sublimit and such new reduced sublimit, but in no
         event shall such exception to the liability exclusion of this paragraph
         (b) exceed $17.5 million. The Seller agrees to use commercially
         reasonable efforts to give the Buyer and the Buyer Sub as much prior
         notice as is practicable of any such reduction in sublimits.

                  (c)      Each of the Seller and Westinghouse and the Buyer and
         the Buyer Sub will waive any right of subrogation any such party may
         have with respect to any liability for an insurable loss covered by
         this Section 10.11.

                  (d)      All losses and damages for which the Seller and
         Westinghouse or the Buyer and the Buyer Sub, as applicable, are not to
         be responsible pursuant to this Section 10.11 are referred to as
         "EXCLUDED CONTAMINATION CLAIMS".

         10.12.   PROPERTY COVERAGE. During the first five years after the
Closing Date, each of the Seller and the Buyer and the Buyer Sub shall cause
their own non-nuclear property insurance policies covering the Seller's Sites
(in the case of the Seller) and the Owned Real Property (in the case of the
Buyer and the Buyer Sub) to provide that, in the event of any loss payment under
such policy, the insurer shall waive rights of subrogation against the Buyer and
the Buyer Sub (in the case of the Seller's insurer) or their insurance carrier
or against the Seller (in the case of the Buyer's and the Buyer Sub's insurer)
or its insurance carrier.

FOR IMMEDIATE RELEASE

                 MOLTEN METAL TECHNOLOGY COMPLETES ACQUISITION
                    OF COMMERCIAL WASTE PROCESSING FACILITY

                     GAINS FULL OWNERSHIP FROM WESTINGHOUSE

WALTHAM, Mass. - December 11, 1996 -- Molten Metal Technology, Inc.
(NASDAQ;MLTN) today announced it has completed the acquisition for full
ownership of the waste-processing facility it previously owned jointly with
Scientific Ecology Group, Inc. (SEG), a subsidiary of Westinghouse Electric
Corporation (NYSE:WX). Located in Oak Ridge, Tenn., the first-of-a-kind
Quantum-CEP[Trademark] (Q-CEP) facility was built to process radioactive ion
exchange resins from commercial nuclear power plants.

         Molten Metal Technology has paid $31 million in cash for SEG's half of
the facility and certain associated wet waste-handling assets. These assets
include contracts, equipment, services and personnel for processing radioactive
waste streams at the Oak Ridge facility.

         "This acquisition will enable Molten Metal Technology to offer full
service to the wet waste side of the important commercial radioactive waste
industry," said Victor E. Gatto, Jr., vice president of government and nuclear
business for Molten Metal Technology. "The acquisition places us in an excellent
strategic position for this market."

         The Q-CEP facility offers services to utilities for processing spent 
ion exchange resins, a form of low-level radioactive waste. Ion exchange resins
consist of beads and powders that become radioactively contaminated when used by
nuclear power plants for water purification. The Q-CEP process is designed to
recover useful, uncontaminated products from radioactive material; reduce the
volume of radioactive material requiring storage by at least 30:1; and produce a
safe, final waste form.

         Molten Metal Technology, Inc. is an environmental technology company
commercializing pollution prevention and waste recycling methods that are
broadly applicable to a wide variety of hazardous, non-hazardous, and
radioactive wastes. Molten Metal Technology is based in Waltham, Massachusetts.

         Certain statements contained in this press release regarding future
events or the future financial performance of Molten Metal Technology are
forward-looking statements within the meaning of federal securities laws. These
statements are based on a number of risks and uncertainties, and actual events
or results could differ materially from the company's expectations as a result
of completion of feasibility studies,

customer acceptance of technology, and the award of government contracts.
Additional factors which may cause actual results to differ are described in the
company's Form 8-K filed with the Securities and Exchange Commission on July 3,
1996.
