Item 2.  Acquisition or Disposition of Assets

      In August 1994, Molten Metal Technology, Inc. (the "Company" or "MMT")
entered into a series of related agreements with Martin Marietta Corporation to
form M4 Environmental L.P. ("M4"), a 50/50 joint venture. Martin Marietta has
since merged into Lockheed Martin Corporation ("LMC"), with LMC as the surviving
entity. Pursuant to these agreements, the Company and LMC formed M4, a Delaware
limited partnership, to commercialize the Company's proprietary Catalytic
Extraction Processing ("CEP") technology to service the environmental
remediation, waste management, decontamination and decommissioning needs of the
U.S. Department of Defense ("DoD"), the U.S. Department of Energy ("DOE") and
the United States Enrichment Corporation. In April 1996, the Company and LMC
expanded M4 through the acquisition by M4 of the Retech division of Lockheed
Environmental Systems & Technologies Co., a wholly-owned subsidiary of LMC. The
Retech division designs and manufactures metallurgical equipment and waste
processing systems that utilize a plasma technology. In June 1997, the Company
and LMC completed a restructuring of their relationship with respect to M4's
market.

      The restructuring entailed five principal changes in the relationship
between LMC and MMT: (1) LMC has the exclusive right to lead and pursue
contracts for the Hanford radioactive tanked waste cleanup project described
below, and MMT will provide directly to LMC certain construction and development
services with respect to Quantum-CEP(R) ("Q-CEP(R)"); (2) MMT and LMC formed a
new limited liability company to be their exclusive vehicle to deliver
processing services to customers in the chemical demilitarization market
worldwide; (3) MMT has the exclusive right to lead and pursue worldwide
opportunities for processing depleted uranium hexafluoride ("DUF(6)"); (4) MMT 
has become the sole owner of M4, which will continue to own and operate its 
primary remaining asset, the M4 Technology Center; and (5) the Retech division 
of M4 has been transferred to LMC.

          Hanford Project. As part of the LMC team for the Hanford project, LMC
offered to purchase and MMT has agreed to deliver a pilot-scale, demonstration
CEP plant in 1997 for a fixed price of $5 million. This plant will be used to
process surrogate Hanford tank waste. Additionally, LMC has agreed to fund
certain development work with respect to Q-CEP for possible application to the
Hanford project. LMC has informed the DOE that LMC currently intends to propose
an alternative technology, vitrification, as its baseline processing technology
for Phase 1B of the Hanford contract. However, in connection with the
development work to be performed by MMT, LMC and MMT have agreed to develop a
technology insertion plan for the possible inclusion of Q-CEP in the Hanford
project if such development work is successful. LMC has informed the DOE of its
intention to develop this technology insertion plan. If the LMC team is awarded
a contract under Phase 1B of the Hanford cleanup program and Q-CEP is used in
the Phase 1B performance, LMC has agreed to pay MMT a fee of $15 million. $5
million of this fee will be payable on award of the contract and the remaining
$10 million will be payable upon timely delivery and acceptance of a CEP
production plant pursuant to terms to be agreed upon by LMC and MMT. MMT also is
entitled to an on-going royalty of 3.5% of all revenues generated from the
processing of waste in equipment supplied by MMT under the Hanford contract.
There can be no assurances that LMC will include Q-CEP in any proposal for


                                       2
<PAGE>   3
any Phase 1B contract or that LMC will submit a bid for Phase 1B. There also can
be no assurances that DOE will award a Phase 1B contract to the LMC team or
that, even if it does so, Q-CEP will prove to be satisfactory to the DOE for
processing the Hanford waste.

            Chemical Weapons Demilitarization. The limited liability company
formed by MMT and LMC has exclusive worldwide rights to commercialize CEP for
the chemical weapons demilitarization market. The limited liability company is
owned 50/50 by subsidiaries of LMC and MMT. MMT is entitled to success fees of
up to an aggregate of $25 million in connection with the successful deployment
of CEP systems to process chemical weapons, each success fee to be paid from
revenues generated by the CEP plant to which it relates. The limited liability
company has an initial term of five years.

      M4 Technology Center. As sole owner of M4, MMT is responsible for the
future operations of the M4 Technology Center, and is entitled to all future
revenues from such operations. The $38 million aggregate principal amount of
bonds issued by the Industrial Development Board of Oak Ridge relating to the M4
Technology Center remain outstanding, LMC's guarantee of these bonds remains in
place, and each of LMC and MMT is responsible for 50% of the principal, interest
and other costs relating to these bonds.

      DUF(6). MMT and LMC have agreed that MMT will have the exclusive right to
lead and pursue worldwide opportunities for processing DUF(6). LMC has agreed 
not to pursue this market for five years except that, at the request of MMT, LMC
will consider participating in this market jointly with MMT on a case-by-case
basis, subject to mutual agreement of the parties.

      LMC and MMT also have established a strategic alliance committee, in the
form of a limited liability company governed by three directors from each
company, to review and monitor the relationships created by the restructuring
and to evaluate new market opportunities within the DOE and DoD markets. Prior
to pursuing any such opportunity alone, each of LMC and MMT will be obligated to
first offer such opportunity to the other party by presenting it to the
strategic alliance committee. The committee would determine whether such
opportunity would be pursued jointly by the parties and the terms thereof. If
the committee does not elect to pursue the opportunity jointly, either party
would be free to pursue it alone.

      In connection with the restructuring, (i) LMC terminated its line of
credit with M4 and deemed the approximately $15.8 million aggregate principal
and accrued interest outstanding thereunder to have been paid in full, and (ii)
MMT contributed $14.6 million in outstanding accounts receivable to the capital
of M4. LMC and MMT generally will share equally in substantially all of the
costs of the restructuring.

                         MASTER RESTRUCTURING AGREEMENT


      This is a Master Restructuring Agreement, dated as of June 16, 1997 (as in
effect from time to time, the "Agreement"), between Molten Metal Technology,
Inc., a Delaware corporation ("MMT"), and Lockheed Martin Corporation, a
Maryland corporation ("LMC").

      WHEREAS, Martin Marietta Corporation, a Maryland corporation ("MMC"), and
MMT entered into a Master Agreement for Government Market Development and
Commercialization of CEP Technology, dated as of August 9, 1994 (as in effect
from time to time, the "Original Agreement"), pursuant to which they formed M4
Environmental L.P., a Delaware limited partnership ("M4"), in order to
effectively commercialize CEP (as hereinafter defined) by selling, engineering,
constructing and operating CEP Plants, and sublicensing CEP technology to
appropriate third parties to permit them to engineer, construct and operate CEP
Plants, to service the environmental remediation, waste management,
decontamination, decommissioning, chemical and biological demilitarization,
pollution prevention and waste minimization needs of the United States
Department of Energy ("DOE") and the United States Department of Defense
("DoD");

      WHEREAS, pursuant to an Agreement and Plan of Reorganization, dated as of
August 29, 1994, between MMC and Lockheed Corporation, a Delaware corporation
("Lockheed"), MMC and Lockheed effected a business combination whereby MMC and
Lockheed became wholly-owned subsidiaries of LMC, a new publicly-held
corporation (the "LMC Merger");

      WHEREAS, subsequent to the LMC Merger, Lockheed and MMC merged with and
into LMC, with LMC as the surviving corporation;

      WHEREAS, pursuant to an Agreement for Additional Market Segment, dated as
of December 13, 1994, MMT and M4 expanded M4's exclusive license to utilize CEP
to include certain materials generated by the United States Enrichment
Corporation;

      WHEREAS, pursuant to a Commercial Mixed Waste Processing Agreement, dated
December 12, 1995, between MMT and M4, MMT granted to M4 a limited license to
utilize CEP Technology for processing commercial mixed waste at M4's processing
facility in Oak Ridge, Tennessee; and

      WHEREAS, MMT, LMC and M4 entered into a Partnership Restructuring
Agreement, dated as of March 15, 1996 (the "Partnership Restructuring
Agreement"), whereby, among other things, M4 acquired substantially all of the
assets of the Retech Division of LMC's wholly-owned subsidiary, Lockheed
Environmental Systems &
<PAGE>   7
                                      -2-


Technologies Co., and M4 and LMC, acting through its Energy and Environmental
Sector ("Sector"), agreed to enter into teaming agreements for certain major
contracts;

      WHEREAS, pursuant to the Agreement For Expansion of License Japanese
Chemical Weapons among M4, MMT and LMC, dated September 26, 1996 ("Japanese
Extension Agreement"), MMT expanded M4's exclusive license to utilize CEP to
include the processing of certain chemical weapons agent for the Japanese
government;

      WHEREAS, M4 has to date developed its technological resources, including
its licensed CEP technology, the Retech plasma technology and additional
technologies, and is pursuing several major markets (collectively, the
"Markets") for these technologies. However, in order to more effectively capture
and penetrate these Markets LMC, through its wholly-owned Subsidiary, Lockheed
Martin Advanced Environmental Systems, Inc., a Delaware corporation ("LMAES"),
and MMT (each of LMC and MMT being sometimes referred to herein as a "Party"
and, collectively, as the "Parties") desire to become more directly involved in
the delivery of these technologies to the Markets in order to most effectively
exploit the core competencies and resources of the Parties, reduce redundancies
arising in connection with the M4 relationship, establish a clearer definition
of the roles and responsibilities of the Parties, and deliver goods and services
to the Markets more efficiently and economically.

      NOW, THEREFORE, the Parties agree as follows:

                                    Article 1

            methodology shall be consistent with the intent of the Parties
            expressed in the first sentence of this paragraph (a).

      (b)   The TWRS Royalty shall be paid on a quarterly basis. Within thirty

            written statement showing the LLFW Revenues generated in such
            quarter and a calculation of the TWRS Royalty payable with respect

            inspect, on a confidential basis, the relevant books and records of
            LMC in order to verify the accuracy of LMC's calculation of the TWRS
            Royalty. Any payment or acceptance of the TWRS Royalty shall be
            without prejudice to MMT's right to dispute the calculation or
            amount of any TWRS Royalty. If MMT disputes any such amount, then
            the Parties shall resolve such dispute pursuant to the Amended and
            Restated Dispute Resolution Agreement.

      4.8. Termination By DOE. In the event that the DOE cancels or otherwise
terminates the initiative represented by the Tanked Waste Contract prior to the
award of the Phase 1B portion of the Tanked Waste Contract, then the
relationship contemplated by this Article 4 shall terminate. In the event that
the DOE effects any such cancellation or termination after the award of the
Phase 1B portion of the Tanked Waste Contract, the Parties' rights and
obligations as against each other and DOE upon the occurrence of such event will
be defined by the definitive agreements described above in this Article 4.

            and expenses, including without limitation the reasonable fees and

            agreed to be responsible pursuant to Section 8.3 or pursuant to
            Article 3 of the Asset Transfer Agreement.

      8.5.  Claims.

      (a)   Notice. Either Party seeking indemnification hereunder (the
            "Indemnified Party") shall promptly notify the other Party hereto
            (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 the
            Indemnifying Party of its obligations under this Article 8 except to
            the extent, if at all, that such Indemnifying Party shall have been
            prejudiced thereby.

      (b)   Third Party Claims. If a Claim relates to any action, suit,
            proceeding or demand instituted against the Indemnified Party by a
            third party (a "Third Party Claim"), the Indemnifying Party shall be
            entitled to participate in the defense of such Third Party Claim
            after receipt of notice of such claim from the Indemnified Party.
            Within thirty (30) days after receipt of notice of a particular
            matter from the Indemnified Party, the Indemnifying Party may assume
            the defense of such Third Party Claim, in which case the
            Indemnifying Party shall have the authority to negotiate, compromise
            and settle such Third Party Claim, if and only if the following
            conditions are satisfied:

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

            (ii)  the Indemnified Party shall not have given 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.
<PAGE>   21
                                      -16-


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. In the event of any Third Party Claim for
which each of the Parties is responsible for 50% pursuant to Sections 8.3(a),
9.3 or 9.4, the SAC LLC will discuss and agree on a joint defense of such Third
Party Claim.

      8.6. Method and Manner of Paying Claims. In the event of any claims for
indemnification under this Article 8, the claimant shall advise the Party that
is required to provide indemnification therefor in writing of the amount and
circumstances surrounding such claim. With respect to a liquidated claim, if
within thirty (30) days the other Party has not contested such claim in writing,
the other Party shall pay the full amount thereof within ten (10) days after the
expiration of such 30-day period. Any amount owed by an Indemnifying Party
hereunder with respect to any Claim may be set-off by the Indemnified Party
against any amounts owed by the Indemnified Party to the Indemnifying Party. The
unpaid balance of a claim for indemnification under this Article 8 shall bear
interest at a rate per annum equal to the lowest prime rate published in the
Wall Street Journal in its "Money Rates" column on the date notice thereof is
given by the Indemnified Party to the Indemnifying Party.

      9.1.  M4-MMT Receivables.

      (a)   Immediately prior to the Closing, the LMC Subsidiary shall
            contribute to M4 cash in the amount of $4,960,000 to fund the
            payment by M4 of a portion of certain outstanding accounts payable
            owed by M4 to MMT relating to amounts previously paid by MMT to its
            subcontractor, Fluor Daniel.

      (b)   MMT agrees that, upon payment of the amount referred to in paragraph
            (a) above and consummation of the other transactions to be completed
            at the Closing, after the Closing neither LMC nor the LMC Subsidiary

      9.3.  Oak Ridge Debt.

      (a)   With respect to the outstanding $38,000,000 aggregate principal
            amount of Solid Waste Facility Bonds (M4 Environmental L.P. Project
            Series 1996) issued by The Industrial Development Board of the City
            of Oak Ridge (the "Oak Ridge Bonds") and the related $38,000,000
            loan made to M4 by The Industrial Development Board of the City of
            Oak Ridge (the "Oak Ridge Loan"), the Parties agree that after the
            Closing M4 shall remain as obligor on the Oak Ridge Loan. However,
            until the Oak Ridge Loan has been paid in full, each Party agrees
            that it will be responsible for 50% of the Oak Ridge Loan and Oak
            Ridge Bonds, including the payment of principal, interest and any
            letter of credit fees payable pursuant to the LC Reimbursement
            Agreement or any agreement relating to a substitute letter of
            credit. LMC agrees to provide funds on a timely basis to MMT or, at
            MMT's direction, M4 as required to cover LMC's 50% share of the
            required debt service on the Oak Ridge Bonds and the Oak Ridge Loan;
            provided, however, LMC may determine in its sole and absolute
            discretion to pay over such funds directly to the Person(s) entitled
            to the receipt of such funds. MMT shall provide evidence to LMC of
            the prompt and timely payment in full by MMT or M4 of all amounts
            payable relating to the Oak Ridge Loan or the Oak Ridge Bonds.

      (b)   Notwithstanding any other provisions of this Agreement or the
            Related Agreements, neither LMC nor MMT shall have any right to
            withhold any amounts payable by it pursuant to this Section 9.3 in
            satisfaction or set-off of any obligation of the other Party.

      (c)   LMC agrees to keep in place the LC Guaranty until the Oak Ridge Loan
            and Oak Ridge Bonds have been paid in full. In addition, if
            requested by MMT in connection with obtaining a substitute letter of
            credit for the letter of credit issued pursuant to the LC
            Reimbursement Agreement, LMC will enter into a substitute guaranty
            agreement on substantially the same terms as the LC Guaranty.

      (d)   LMC acknowledges that, in connection with the amendment and
            restatement of M4's limited partnership agreement contemplated by
            Section 15.1, LMC will not after Closing be entitled to a 2%
            guaranty fee for providing a guaranty in connection with the Oak
            Ridge Loan and Oak Ridge Bonds.

            LMC and MMT agree that, consistent with Section 8.3(a), except as
            expressly set forth in Schedule 9.4(a) they shall each bear 50% of
            the costs provided for in the HR Plan. In addition, LMC agrees that
            it shall be solely responsible for any severance costs beyond those
            contemplated in the HR Plan.

                                   ARTICLE III

                       PURPOSES AND POWERS OF THE COMPANY

         SECTION 3.1. PURPOSES.

                  (a) GENERAL PURPOSES. The purposes of the Company are (i)
directly, or indirectly through the ownership of interests in other entities, to
engage in the processing of Chem Weapons Feedstocks worldwide (the "Chem Demil
Market"), and (ii) to engage in all related activities arising therefrom or
relating thereto or necessary, desirable, advisable, convenient, incidental or
appropriate in connection therewith as the Board may from time to time
determine.

                  (b) INTENTION OF MEMBERS. The LMC Subsidiary shall take the
lead in marketing and business development opportunities, and shall have final
approval over which projects the Company elects to bid. The Company shall pursue
the Chem Demil Market using multiple technologies to offer the best value to the
customer. The Company may utilize CEP or any other technology. The Company shall
pursue particular market opportunities either directly or through separate
project entities created by the Company or the Members for particular projects
or through prime/subcontract relationships created for particular projects. Each
Member shall be responsible for its own personnel costs and marketing costs,
including bid and proposal costs ("B&P Costs"), it being understood that B&P
Costs may be recovered in whole or in part if a contract is awarded to the
Company, subject to the mutual advance agreement of the Members and final audit.
Except as provided in the two (2) immediately following sentences, ownership,
funding, profits and losses with respect to each project of the Company shall be
shared on a

                                      -7-
<PAGE>   8
50/50 basis, all Capital Contributions shall be made in equal shares by the LMC
Subsidiary and the MMT Subsidiary and the Percentage Interest of each of the LMC
Subsidiary and the MMT Subsidiary shall be fifty percent (50%). However, in
connection with a particular Company project the Members may decide to vary this
50/50 relationship in one or more respects based on the technology selected for
such project, the respective financial commitments made for such project by the
Members and the amount of the Capital Contribution each Member is willing to
make for such project. In the event that either the LMC Subsidiary or the MMT
Subsidiary proposes any such variation in the 50/50 relationship as a result of
a project to be performed by the Company (as distinguished from a project to be
performed by a separate project entity created by the Company or the Members or
a project to be performed through a prime/subcontract relationship), before the
Company may undertake such a project, this Agreement shall be amended with the
unanimous consent of the Members so as to reflect the understanding and
agreement of the Members with respect to such variation in the 50/50
relationship, including, without limitation, appropriate amendments to Articles
VIII, IX and X, and, as provided in the definition of "Percentage Interest"
contained in Section 1.1, to reflect adjustments in the respective Percentage
Interests of the Members, either with respect to such project only or with
respect to the Company as a whole. The Members acknowledge that their intent is
to structure these relationships so as to maximize the competitive position of
the Company and its projects and the likelihood of Company success.

                  (c) CHEM DEMIL EQUIPMENT AND TECHNOLOGY. To the extent that
either LMC or MMT or any Affiliate controlled by either of them owns or controls
equipment or technology that can be sold in the Chem Demil Market, in the event
that such Person or such Affiliate determines to sell or license such equipment
or technology for use in the Chem Demil Market for the Treatment (as defined in
the Master Restructuring Agreement) or Recycling (as defined in the Master
Restructuring Agreement) of Chem Weapons Feedstocks, such Person shall, or cause
its applicable Affiliate to, appoint the Company to act as the exclusive
distributor for sale to third parties of such equipment or technology. Any
profits realized by the Company in connection with such distribution activity
shall be shared equally by the Members unless they agree otherwise.

                  (d) ABILITY OF MEMBERS TO ACQUIRE COMPETING BUSINESSES. The
intent of the Members is that either initial Member or its Affiliates will be
free to acquire other businesses at any time even if any such acquired business
would include a chemical weapons demilitarization line of business. However, as
required in Section 11.3 of the Master Restructuring Agreement, such acquired
business will be required to pursue the Chem Demil Market through the Company
for the term of the Company, as provided in Section 2.5.

                  (e) EXCLUSIVITY. Each of the Members shall comply with the
provisions of Section 11.3 of the Master Restructuring Agreement.

         SECTION 3.2. POWERS.

                  (a) SPECIFIC POWERS OF COMPANY. Subject to Section 5.14, the
Company, and the Board on behalf of the Company, shall have the power and
authority to take any and all

                                      -8-

disqualification of a member of a committee, the Director or Directors thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another Director to act at the
meeting in place of such absent or disqualified member of such committee. Any
such committee, to the extent permitted by law and to the extent provided in the

the powers and authority of the Board in the management of the business and
affairs of the Company. On all committees of the Board there shall be an equal

         SECTION 6.1. OFFICERS. The Officers of the Company shall be chosen by
the Board, except as otherwise provided herein. Except as otherwise provided
herein, the Officers shall have such powers and duties in the management of the
Company as may be prescribed in a resolution by the Board and, to the extent not
so provided, as generally pertain to their respective offices as if the Company
were a corporation governed by the General Corporation Law of the State of
Delaware, subject to the control of the Board. The Board may require any
Officer, agent or employee to give security for the faithful performance of his
or her duties. Each Officer shall hold office until his or her successor is

attend all meetings of the Board and all meetings of the Members and record all
of the proceedings of the meetings of the Company and of the Board in a book to
be kept for that purpose and shall perform like duties for the standing

of all meetings of the Members and special meetings of the Board, and shall
perform such other duties as may be prescribed by the Board, or the President if
any, under whose supervision the Secretary shall be. The Assistant Secretary or,

                                      -16-
<PAGE>   17
the Assistant Secretaries in the order determined by the Board (or if there be
no such determination, then in the order of their election) shall, in the
absence of the Secretary, or in the event of the Secretary's inability to act,
perform the duties and exercise the powers of the Secretary and shall perform
such other duties and have such other powers as the Board, or the President if
any, may from time to time prescribe.

         SECTION 6.3. THE TREASURER AND ASSISTANT TREASURER. The Treasurer, if
any, shall have the custody of the Company's funds and securities and shall keep

and to the credit of the Company in such depositories as may be designated by
the Board. The Treasurer shall disburse the funds of the Company as may be
ordered by the Board or the President, taking proper vouchers for such
disbursements, and shall render to the Board, at its regular meetings, or when
the Board so requires, an account of all the Treasurer's transactions and of the
financial condition of the Company. The Assistant Treasurer or, if there shall
be more than one, the Assistant Treasurers in the order determined by the Board
(or if there be no such determination, then in the order of their election),
shall, in the absence of the Treasurer, or in the event of the Treasurer's
inability to act, perform the duties and exercise the powers of the Treasurer
and shall perform such other duties and have such other powers as the Board, or
the President if any, may from time to time prescribe.

         SECTION 6.4. OFFICERS AS AGENTS. The Officers, to the extent of their
powers set forth in this Agreement, are agents of the Company for the purpose of
the Company's business, and the actions of the Officers taken in accordance with
their respective powers set forth in this Agreement shall bind the Company.
Without limiting the generality of the foregoing, no Officer shall have any
power or authority or right to act for or bind the Company with respect to any
matter unless previously authorized by the Board or, where required pursuant to
Section 5.14, by the Members.

         SECTION 6.5. EXECUTION OF INSTRUMENTS; RELIANCE BY THIRD PARTIES. Any
Person dealing with the Company or any Member, Director or Officer in connection
with the business of the Company, may rely upon a certificate signed by at least

MMT Subsidiary as to:

                           (i) the identify of a Member, Director or Officer;

                           (ii) the existence or non-existence of any fact or

                                   ARTICLE VII

                       TRANSFERABILITY OF MEMBER INTERESTS

         SECTION 7.1.  RESTRICTIONS ON TRANSFER.

                  (a) No Member shall have the right to dispose of, sell,
alienate, assign, participate, subparticipate, encumber, or otherwise transfer
all or any part of its Interest (other than an assignment by operation of law,
such as a merger), unless prior to such transfer the transferee is approved in
writing by all of the other Members acting in their sole and absolute
discretion.

                  (b) The transferee of the Interest of a Member may become a
substituted Member only upon the terms and conditions set forth in this Article
VII. Each Member shall have the power, in its sole discretion, to admit or to
refuse to admit as substituted Members transferees who acquire the Interest, or
any part thereof, of a Member hereunder. Except as otherwise provided in this
Article VII, the failure or refusal of the Members to admit an assignee as a
substituted Member shall not affect the right of such assignee to receive the
share of distributions of the Company to which its predecessor in interest would
have been entitled; however, the assignee of the assigned Interest shall not be
entitled to exercise any rights of a Member of the Company, including without
limitation the right to vote or consent with respect to any proposed action of
the Company as to which such vote or consent is required, unless and until the
assignee is admitted as a substituted Member. From and after the assignment of
any Interest or portion thereof, the assignor shall not be entitled to exercise
any rights of a Member of the Company in respect of the Interest or portion
thereof assigned, including without limitation the right to vote or consent with
respect to any proposed action of the Company, regardless of whether its
assignee becomes a substituted Member. An assignee of a Member's Interest who
does not become a substituted Member as provided herein and who desires to make
a further assignment of its Interest shall be subject to all of the provisions
of this Article VII to the same extent as any Member desiring to make an
assignment.

                  (c) In addition to the foregoing requirements, the admission
of an assignee as a substituted Member shall be conditioned upon the assignee's
written acceptance of the terms and provisions of this Agreement and its written
assumption of the obligations hereunder of its assignor. Whether or not a
transferee who acquired any Interest in the Company has accepted in writing the
terms and provisions of this Agreement and assumed in writing the obligations
hereunder of its predecessor in interest, such transferee shall be deemed, by
the acquisition of such Interest, to have agreed to be subject to and bound by
all the obligations of this Agreement with the same effect and to the same
extent as any predecessor in interest of such transferee.

                  (d) All costs incurred by the Company in connection with the
admission to the Company of a substituted Member pursuant to this Article VII
shall be borne by the transferor Member (and if not timely paid, by the
substituted Member), including, without limitation, costs of any necessary
amendment hereof, filing fees, if any, and reasonable attorneys' fees.

         SECTION 7.2. ADDITIONAL RESTRICTIONS. Anything contained in the
foregoing provisions of this Article VII expressed or implied to the contrary
notwithstanding:

                  (a) In no event shall a sale, transfer, assignment, exchange,
or other disposition of any Member's Interest take place if such sale transfer,
assignment, exchange, or other disposition would, in the opinion of tax counsel
to the Company, cause a termination of the Company within the meaning of Section
708 of the Code.

                  (b) The Members may, in addition to any other requirement that
the Members may impose, require as a condition of any sale, transfer,
assignment, exchange, or other disposition of any Interest in the Company that
the transferor furnish to the Company an opinion of counsel satisfactory (both
as to such opinion and as to such counsel) to counsel to the Company that such
sale, transfer, assignment, exchange, or other disposition complies with
applicable federal and state securities laws.

                  (c) Any sale, transfer, assignment, exchange, or other
disposition in contravention of any of the provisions of this Article VII shall
be void and ineffectual and shall not bind or be recognized by the Company.

                                  ARTICLE VIII

                                  DISTRIBUTIONS

                  SECTION 8.1. DISTRIBUTIONS. If at any time and from time to
time (other than in connection with the dissolution and termination of the
Company pursuant to Article X) the Board determines that the Company has cash
that is not required for the operations of the Company, the payment of
liabilities or expenses of the Company, or the setting aside of reserves to meet
the anticipated cash needs of the Company, the Board shall distribute all or any
portion of that excess cash to the Members in proportion to their Percentage
Interests.

                  SECTION 8.2. RESTRICTED DISTRIBUTIONS. The Company, and the
Board on behalf of the Company, shall not be required to make a distribution to
any Member on account of its Interest if and to the extent that such
distribution would violate (i) Section 18-607 of the Delaware Act, (ii) Section
2.4(d) of the MMT License Agreement, or (iii) other applicable law.

                                   ARTICLE IX

                        ALLOCATIONS OF PROFITS AND LOSSES

         SECTION 9.1. ALLOCATIONS OF PROFITS. Except as provided in Section 9.4,
all net profits and credits of the Company (for both accounting and tax
purposes) for each Fiscal Year shall be allocated to the Members from time to
time (but no less often than annually and before making any distribution to the
Members) in proportion to their Percentage Interests.

         SECTION 9.2. ALLOCATIONS OF LOSSES. Except as provided in Section 9.4,
all net losses of the Company for each Fiscal Year (for both accounting and tax
purposes) shall be allocated to the




                                      -19-
<PAGE>   20
Members from time to time (but no less often than annually and before making any
distribution to the Members) in proportion to their Percentage Interests.

         SECTION 9.3. CALCULATION OF PROFITS AND LOSSES. For all purposes
hereof, the Company's profits and losses shall be determined by taking into
account all of the Company's items of income and gain (including items not
subject to federal income tax) and all items of loss, expense, and deduction, in
each case determined under federal income tax principles. For both accounting
and tax purposes, the books and records of the Company shall be kept on the
accrual method of accounting applied in a consistent manner.

         SECTION 9.4. SECTION 704(C) OF THE CODE AND CAPITAL ACCOUNT REVALUATION
ALLOCATIONS. The Members agree that to the full extent possible with respect to
the allocation of depreciation, amortization or any other cost recovery
deduction, loss and gain, solely for federal income tax purposes, Section 704(c)
of the Code shall apply with respect to non-cash property contributed to the
Company by any Member. Accordingly, (i) if the tax basis of any property
contributed differs from its agreed fair market value for purposes of
determining Capital Accounts (the "Section 704(c) Difference"), on the sale of
all or a portion of such property, any tax gain or loss resulting, up to the
dollar amount of the Section 704(c) Difference as adjusted by any prior
allocations under this clause (i) and prior allocations of depreciation,
amortization or other cost recovery deduction as provided under clause (ii)
below, shall be specially allocated to the contributing Member; and (ii), to the
extent of the Section 704(c) Difference, any remaining tax depreciation,
amortization or other cost recovery deductions with respect to such property
shall, for each Fiscal Year, be specially allocated to the other Members, up to
an amount equal to the amount of depreciation, amortization or other cost
recovery deductions with respect to such property allocated to such other
Members for purposes of determining Capital Accounts, and the balance of such
tax depreciation, amortization or other cost recovery deduction with respect to
such property shall be allocated to the contributing Member, and the Section
704(c) Difference shall be reduced by an amount equal to the difference between
the amount of tax depreciation, amortization or other cost recovery deduction
with respect to such property for such Fiscal Year so allocated to the Members
and the amount allocated to the Members for purposes of determining Capital
Accounts. For purposes hereof, any allocation of income, loss, gain or any item
thereof to a Member pursuant to Section 704(c) of the Code shall be for income
tax purposes only and shall not affect its Capital Account in the Company. In
addition to the foregoing, if Company assets are reflected in the Capital
Accounts of the Members at a book value that differs from the adjusted tax basis
of such assets (e.g., because of a revaluation of the Members' Capital Accounts
under Treasury Regulations 1.704-l(b)(2)(iv)(f)), allocations of depreciation,
amortization, or other cost recovery deduction, income, gain or loss with
respect to such property shall be made among the Members in a manner consistent
with the principles of Section 704(c) of the Code and this Section 9.7.

                  pursuant to Section 5.14(a)(vii); or

                           (vi) upon the entry of a decree of judicial
                  dissolution pursuant to Section 18-802 of the Delaware Act.

                  (b) (i) Upon dissolution of the Company, the business of the
                  Company shall continue for the sole purpose of winding up its
                  affairs. The winding up process shall be carried out by the
                  Board unless the Members (including any Member that is the
                  subject of a Bankruptcy as provided in Section 10.1(a)(ii) or
                  (iii) and a breaching Member as provided in Section
                  10.1(a)(iv)) unanimously agree to appoint a liquidating
                  trustee (the Board or such liquidating trustee, as the case
                  may be, being referred to herein as the "Liquidator"). In
                  winding up the




                                      -21-
<PAGE>   22
                  Company's affairs, every effort shall then be made to dispose
                  of the assets of the Company in an orderly manner, having
                  regard to the liquidity, divisibility and marketability of the
                  Company's assets and consistent with the considerations set
                  forth in paragraph (ii) of this subsection (b). If the
                  Liquidator determines that it would be imprudent to dispose of
                  any non-cash assets of the Company, such assets may be
                  distributed in kind to the Members, in lieu of cash,
                  proportionately to their rights to receive cash distributions
                  hereunder; provided, that the Liquidator shall in its sole
                  discretion determine the relative shares of the Members of
                  each kind of those assets that are to be distributed in kind.
                  The Liquidator shall not be entitled to be paid by the Company
                  any fee for services rendered in connection with the
                  liquidation of the Company, but shall be reimbursed by the
                  Company for all third-party costs and expenses incurred by it
                  in connection therewith and shall be indemnified by the
                  Company with respect to any action brought against it in
                  connection therewith by applying, mutatis mutandis, the
                  provisions of Article XII.

                           (ii) In winding up the business of the Company, the
                  Liquidator shall wind up the Company in an orderly and prudent
                  manner consistent with the Company's then-existing obligations
                  (including with respect to developed CEP Plants or other
                  projects) and the Company's pending and prospective projects,
                  with the goals of fulfilling the Company's contractual
                  obligations, protecting customer goodwill and assuring
                  customer service, limiting any residual liability to the
                  Members and effecting a division of assets consistent with the
                  relative Capital Account balances of the Members. The Members
                  may elect to wind up the relationship contemplated by this
                  Agreement by causing the sale by one Member of its Interest or
                  one or more CEP Plants or other projects owned by the Company
                  or sublicensed by the Company to the other Member.

                  (c) The occurrence of the Bankruptcy of a Member shall not
                  cause a Member to cease to be a member of the Company, and,
                  except as expressly provided in Section 10.1(a)(ii), (iii),
                  (iv) or Section 10.1(b), upon the occurrence of such an event,
                  the business of the Company shall be continued without
                  dissolution.

         SECTION 10.2. APPLICATION AND DISTRIBUTION OF COMPANY ASSETS. The
assets of the Company in winding up shall be applied or distributed as follows:
first, to creditors of the Company (including Members that are creditors),
whether by payment or the making of reasonable provision for the payment
thereof, and including any contingent, conditional and unmatured liabilities of
the Company, taking into account the relative priorities thereof, and second, to
the Members in proportion to their respective Percentage Interests. A reasonable
reserve for contingent, conditional and unmatured liabilities in connection with
the winding up of the business of the Company shall be retained by the Company
until such winding up is completed or such reserve is otherwise deemed no longer
necessary by the Liquidator.

         SECTION 10.3. CAPITAL ACCOUNT ADJUSTMENTS. For purposes of determining
a Member's Capital Account, if, on liquidation and dissolution of the Company,
some or all of the assets of the Company are distributed to the Members in kind,
Company profits (or losses) shall be




                                      -22-
<PAGE>   23
increased by the profits (or losses) that would have been realized had such
assets been sold for their respective fair market values on the date of
dissolution of the Company, as determined by the Liquidator. Any such increase
pursuant to the preceding sentence (i) shall be allocated to the Members in
accordance with Article IX, and (ii) shall increase (or decrease) the Members'
Capital Account balances accordingly.

         SECTION 10.4. TERMINATION OF COMPANY. The Company shall terminate when
all assets of the Company, after payment of or due provision for all debts,
liabilities and obligations of the Company, shall have been distributed to the
Members in the manner provided for in this Article X, and the Certificate shall
have been canceled in the manner required by the Delaware Act.

         SECTION 11.1. COMPANY BOOKS OF ACCOUNT. The Board shall cause to be
entered in appropriate books, kept at the Company's principal place of business,
all transactions of or relating to the Company. Each Member shall have access to
and the right, at such Member's sole cost and expense, to inspect and copy such
books and all other Company records during normal business hours; provided that
the inspecting Member shall be responsible for any out-of-pocket costs or
expenses incurred by the Company in making such books and records available for
inspection. The Board shall not have the right to keep confidential from the
Members any information that the Board would otherwise be permitted to keep
confidential pursuant to Section 18-305(c) of the Delaware Act.

         SECTION 11.2. DEPOSITS OF COMPANY FUNDS. All funds of the Company shall
be deposited in the Company's name in such checking, money market, or other

shall be made therefrom on such signature or signatures as the Board shall
determine.

         SECTION 11.3. FINANCIAL STATEMENTS; REPORTS TO MEMBERS. The Board shall
cause the Company, at its cost and expense, to prepare and furnish to each of
the Members, within ninety (90) days after the close of each Fiscal Year,
audited financial statements of the Company, and all other information necessary
to enable such Member to prepare its tax returns, including, without limitation,
from time to time a statement showing the balance in such Member's Capital
Account as of the close of such Fiscal Year, and changes therein during such
Fiscal Year.

         SECTION 11.4. TAX MATTERS PARTNER. The LMC Subsidiary shall be the tax
matters partner of the Company within the meaning of Section 6231(a)(7) of the
Code. However, as the tax matters partner, the LMC Subsidiary shall not make any
filing with the Internal Revenue Service or other tax authority, settle any tax
matter, make any election (including but not limited to elections relating to
depreciation and elections pursuant to Section 754 of the Code) or take any
other action that could have an effect on any other Member, without the prior
written consent of each other Member. The tax matters partner shall not be
entitled to be paid by the Company any fee for services rendered by it in
connection with any tax proceeding, but shall be reimbursed by the Company for
all out-of-pocket costs and expenses incurred by it in connection with any




                                      -23-
<PAGE>   24
such proceeding and shall be indemnified by the Company with respect to any
action brought against it in connection with the settlement of any such
proceeding by applying, mutatis mutandis, the provisions of Article XII.

         SECTION 11.5. TAX CLASSIFICATION. It is the intention of the Members
that the Company be classified as a partnership for federal income tax purposes,
and the provisions of this Agreement shall be interpreted in a manner consistent
with such intention. No election shall be filed by or on behalf of the Company
to have the Company classified as other than a partnership for federal tax
purposes without the prior unanimous consent of all Members.

                   LIABILITY, EXCULPATION AND INDEMNIFICATION

         SECTION 12.1. LIABILITY. Except as otherwise provided by the Delaware
Act, the debts, obligations and liabilities of the Company, whether arising in
contract, tort or otherwise, shall be solely the debts, obligations and
liabilities of the Company, and no Covered Person shall be obligated personally
for any such debt, obligation or liability of the Company solely by reason of
being a Covered Person.

         SECTION 12.2. EXCULPATION.

                  (i) No Covered Person shall be liable to the Company or any
         other Covered Person for any loss, damage or claim incurred by reason
         of any act or omission performed or omitted by such Covered Person in
         good faith on behalf of the Company and in a manner reasonably believed
         to be within the scope of authority conferred on such Covered Person by
         this Agreement, except that a Covered Person shall be liable for any
         such loss, damage or claim incurred by reason of such Covered Person's
         gross negligence or willful misconduct.

                  (ii) A Covered Person shall be fully protected in relying in
         good faith upon the records of the Company and upon such information,
         opinions, reports or statements presented to the Company by any Person
         as to matters the Covered Person reasonably believes are within such
         other Person's professional or expert competence and who has been
         selected with reasonable care by or on behalf of the Company, including
         information, opinions, reports or statements as to the value and amount
         of the assets, liabilities, profits, losses, or any other facts
         pertinent to the existence and amount of assets from which
         distributions to Members might properly be paid.

         SECTION 12.3. DUTIES AND LIABILITIES OF COVERED PERSONS.

                  (i) To the extent that, at law or in equity, a Covered Person
         has duties (including fiduciary duties) and liabilities relating
         thereto to the Company or to any other Covered Person, a Covered Person
         acting under this Agreement shall not be liable to the Company or to
         any other Covered Person for its good faith reliance on the provisions
         of this Agreement. The provisions of this Agreement, to the extent that
         they restrict the




                                      -24-
<PAGE>   25
         duties and liabilities of a Covered Person otherwise existing at law or
         in equity, are agreed by the parties hereto to replace such other
         duties and liabilities of such Covered Person.

                  (ii) Unless otherwise expressly provided herein, (a) whenever
         a conflict of interest exists or arises between Covered Persons, or (b)
         whenever this Agreement or any other agreement contemplated herein or
         therein provides that a Covered Person shall act in a manner that is,
         or provides terms that are, fair and reasonable to the Company or any
         Member, the Covered Person shall resolve such conflict of interest,
         taking such action or providing such terms, considering in each case
         the relative interest of each party (including its own interest) to
         such conflict, agreement, transaction or situation and the benefits and
         burdens relating to such interests, any customary or accepted industry
         practices, and any applicable generally accepted accounting practices
         or principles. In the absence of bad faith by the Covered Person, the
         resolution, action or term so made, taken or provided by the Covered
         Person shall not constitute a breach of this Agreement or any other
         agreement contemplated herein or of any duty or obligation of the
         Covered Person at law or in equity or otherwise.

                  (iii) Whenever in this Agreement a Covered Person is permitted
         or required to make a decision (a) in its "discretion" or under a grant
         of similar authority or latitude, the Covered Person shall be entitled
         to consider such interests and factors as it desires, including its own
         interests, and shall have no duty or obligation to give any
         consideration to any interest of or factors affecting the Company or
         any other Person, or (b) in its "good faith" or under another express
         standard, the Covered Person shall act under such express standard and
         shall not be subject to any other or different standard imposed by this
         Agreement or other applicable law.

         SECTION 12.4. INDEMNIFICATION. To the fullest extent permitted by
applicable law, a Covered Person shall be entitled to indemnification from the
Company for any loss, damage or claim incurred by such Covered Person by reason
of any act or omission performed or omitted by such Covered Person in good faith
on behalf of the Company and in a manner reasonably believed to be within the
scope of authority conferred on such Covered Person by this Agreement, except
that no Covered Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Covered Person by reason of gross
negligence or willful misconduct with respect to such acts or omissions;
provided, however, that any indemnity under this Section 12.4 shall be provided
out of and to the extent of Company assets only, and no Covered Person shall
have any personal liability on account thereof.

         SECTION 12.5. EXPENSES. To the fullest extent permitted by applicable
law, expenses (including legal fees) incurred by a Covered Person in defending
any claim, demand, action, suit or proceeding shall, from time to time, be
advanced by the Company prior to the final disposition of such claim, demand,
action, suit or proceeding upon receipt by the Company of an undertaking by or
on behalf of the Covered Person to repay such amount if it shall be determined
that the Covered Person is not entitled to be indemnified as authorized in
Section 12.4.

SECTION 12.6. INSURANCE. The Company may purchase and maintain insurance, to the
extent and in such amounts as the Board shall, in its sole discretion, deem
reasonable, on behalf of Covered Persons and such other Persons as the Board
shall determine, against any liability that may be asserted against or expenses
that may be incurred by any such Person in connection with the activities of the
Company or such indemnities, regardless of whether the Company would have the
power to indemnify such Person against such liability under the provisions of
this Agreement. The Board and the Company may enter into indemnity contracts
with Covered Persons and adopt written procedures pursuant to which arrangements
are made for the advancement of expenses and the funding of obligations under
Section 12.5 and containing such other procedures regarding indemnification as
are appropriate.

                                                  The Company shall have the
obligation to take all actions reasonably necessary to oppose or defend any
Third Party Claim. In the course of defending any such Third Party Claim, the
Company shall consult with the Indemnitees in connection with all material
issues relating to such defense and shall consult the Indemnitees prior to
commencing the same and shall consider any recommendations by the Indemnitees
with respect to the conduct and settlement or compromise thereof and any
reasonable alternative resolutions of the Third Party Claim. In the event that

                  sublicensees.

      4.5. Treatment of Licensed Software Programs. Any Licensed Software
Programs furnished by MMT to the LLC shall be furnished in object code form only
(i.e., in magnetic or electronic binary form on software media, which are
readable and usable by machines, but not generally readable by humans without
reverse assembly, reverse compiling or reverse engineering). The LLC agrees that
it will not attempt to modify, disassemble, decompile, reverse-engineer or
otherwise endeavor to discover or disclose the methods and concepts embodied in
the Licensed Software Programs. All Licensed Software Programs shall be marked
with such copyright, patent, proprietary legends, restrictions or other notices
as MMT may request, and the LLC agrees not to remove or destroy any such mark or
notice on any of the Licensed Software Programs.

      4.6. Disclosure to Government Authorities. The Technical Liaisons shall
promptly establish and implement all procedural safeguards required or advisable
in connection with the performance of government contracts to protect the

      (a)   In order to ensure that each of the LLC, LMC and MMT complies with

            shall meet from time to time as required to discuss issues relating
            to confidentiality and disclosure and other matters addressed by
            this Article 4.

      (b)   With respect to any disclosure by the LLC to any of its officers or
            employees permitted pursuant to Section 4.2(b)(ii) or Section
            4.3(b)(ii), the LLC shall cause each of its officers and employees
            to sign employee non-disclosure and invention agreements in the form
            attached as Annex A hereto or in such other form as is approved from
            time to time by the MMT Technical Liaison ("Employee Non-Disclosure
            Agreements").
<PAGE>   16
                                      -16


      (c)   With respect to any disclosure by the LLC, MMT or LMC to any of its
            Advisors or by the LLC to any prospective customers, vendors,
            suppliers or other third Persons as permitted in Sections 4.2-4.4,
            the Technical Liaison will institute procedures designed to maintain
            the confidentiality of MMT Confidential Information, the LLC
            Confidential Information and LMC Confidential Information while
            facilitating the LLC's business activities. These procedures shall
            include the preparation of standard forms of confidentiality
            agreements to be used by the LLC in connection with its business.

      (d)   The Technical Liaisons will implement a program for the use of
            patent markings by the LLC as appropriate to fully protect the
            Licensed Patents and Licensed Patent Applications in each applicable
            country where they exist.

      4.8. Quality Control. The LLC shall provide to MMT a reasonable
opportunity to inspect the CEP Plants using the MMT Licensed Property and the
services provided by the LLC under the Licensed Trademarks (collectively, the
"LLC Services"), upon MMT's reasonable request from time to time, no more
frequently than four times per year (or more often as is required in the event
that MMT determines in good faith that an emergency condition exists), in order
to enable MMT to maintain an appropriately high level of quality commensurate
with the valuable goodwill associated with the Trademarks (the "Quality
Standard"). If MMT reasonably determines that the applicable CEP Plants or the
LLC Services being performed by the LLC do not meet the Quality Standard, MMT
shall provide the LLC with written notice (the "Failure Notice") of such
failure, specifying the particular aspect of the applicable CEP Plants or the
LLC Services which MMT claims does not meet the Quality Standard and the
particular failure, together with any supporting documentation of such failure.
If the LLC shall not have met such Quality Standard for such LLC Services and
does not (i) take appropriate action to diligently commence to cure such failure
within thirty (30) days after receipt of the Failure Notice and (ii) cure such
failure by causing such LLC Services to meet such Quality Standard and provide
documentation of such cure reasonably acceptable to MMT within sixty (60) days
after the receipt of the Failure Notice (or, if such failure is not reasonably
susceptible to cure within such 60-day period, within 120 days after the receipt
of the Failure Notice), MMT may pursue any available remedies pursuant to the
Dispute Resolution Agreement.

      4.9. Corporate Names. The LLC shall be entitled to refer to MMT and LMC in
its advertising and other promotional materials, subject to compliance with
guidelines, to be adopted by the Board of Directors of the LLC, addressing the
need to maintain a separate legal identity for the LLC, to identify the LLC as a
licensee of the MMT Licensed Property and similar concerns.

            assignments and other instruments and documents as MMT may consider
            necessary or appropriate to carry out the intent of this Section
            5.1. MMT shall be solely responsible for all decisions relating to
            seeking or maintaining patent or copyright or other protection for
            any Improvement or Related Technology, and shall be responsible for
            all expenses incurred in obtaining and maintaining any such

            come within the definition of MMT Licensed Property, will be subject
            to the licenses granted by MMT pursuant to Section 2.1, and LLC
            shall not be required to pay any royalties or other fees for the
            license of such Improvements and Related Technology. MMT shall have
            the unrestricted right to license any of the Improvements or Related
            Technology to any third parties without notice or accounting to the
            LLC.

      6.1. Obligations To Sublicense. In order to commercialize CEP technology
for Chem Weapons Feedstocks, the LLC shall create and implement a comprehensive
program to promote sublicensing of the MMT Licensed Property to appropriate
third parties in order to permit them to establish, own, permit, finance,
construct, start-up and operate CEP Plants located anywhere in the world that
process Chem Weapons Feedstocks.

                                  Infringements

      7.1.  Detection of Infringements, Etc.

      (a)   MMT and the LLC shall use their respective reasonable efforts to
            detect any infringement, misappropriation, violation, dilution or
            unauthorized or improper use of the MMT Licensed Property or unfair
            competition related to the Licensed Trademarks (collectively,
            "Infringements", and individually an "Infringement"). In the event
            that either MMT or the LLC shall become aware of any such
            Infringement, or of any claim that the use of the MMT Licensed
            Property infringes, misappropriates, violates or dilutes any
            proprietary right or property of any third Person, or of any product
            liability claim or action based on or arising out of the use of the
            MMT Licensed Property by either MMT or the LLC, such party shall
            promptly give written notice thereof to the other parties.

      (b)   As part of the Technical Liaisons' regular meetings referred to in
            Article 3, the Technical Liaisons shall discuss any issues related
            to Infringement or the other matters referred to in paragraph (a)
            above.

      7.2. Infringements of MMT Licensed Technology. In the event of any
Infringement of the MMT Licensed Property which is materially and adversely
affecting the Chem Demil Market, MMT shall undertake all actions reasonably
required to redress, oppose, prevent, or restrain such Infringement. In the
event that MMT does not take appropriate actions with a view to addressing such
Infringement within ninety (90) days of MMT becoming aware of such Infringement
(as evidenced by the written notice thereof given by MMT or the LLC to the other
party as provided in Section 7.1 above), the LLC will have the right to commence
such a legal action or proceeding to the extent reasonably required to redress,
oppose, prevent, or restrain such Infringement. Either party bringing any such
legal action or proceeding shall consult with the other party prior to
commencing the same and shall consider any recommendations by the other party
with respect to the conduct and settlement or compromise thereof and any
reasonable alternative resolutions of the Infringement matter. Each party shall
cooperate as may be
<PAGE>   19
                                      -19-


reasonably necessary or appropriate in the prosecution, settlement or compromise
of any such legal action or proceeding commenced by the other party in respect
of any Infringement of the MMT Licensed Property, and agrees to be joined as a
party to any such action or proceeding if it is deemed to be necessary or
desirable by counsel retained by the other party for the prosecution of such
action or proceeding. If either party proceeds to bring any legal action or
proceeding pursuant to the procedure provided for in this Section 7.2, MMT will
bear all reasonable costs of such action or proceeding and will be entitled to
receive and retain all proceeds realized as a result of any settlement thereof
or any judgment thereon ("Proceeds"). However, in the event that MMT receives
any Proceeds, and any portion of such Proceeds is directly attributable to
Infringement that adversely affected the Chem Demil Market, MMT shall remit to
the LLC, after reimbursement of MMT's costs of such action or proceeding, such
portion of such Proceeds.

      7.3. MMT Infringement Claims. Except for any claim to be defended by the
LLC pursuant to Section 7.4, in the event of any claim that any MMT Licensed
Property, or any equipment, material or process based on or utilizing MMT
Licensed Property, infringes, misappropriates, violates or dilutes any
proprietary right or property of any third Person (each an "MMT Infringement
Claim"), then, subject to Section 7.5 below MMT shall have the obligation to
take all actions reasonably necessary to oppose or defend such claims and to pay
any judgment or settlement amount awarded or obtained with respect to such MMT
Infringement Claim. In the course of opposing or defending any such MMT
Infringement Claim, MMT shall consult with the LLC in connection with all
material issues relating to such opposition or defense and shall consult with
the LLC prior to commencing the same and shall consider any recommendations by
the LLC with respect to the conduct and settlement or compromise thereof and any
reasonable alternative resolutions of the MMT Infringement Claim. In the event
that MMT does not undertake to oppose or defend any such action within ninety
(90) days after MMT becomes aware of such MMT Infringement Claim, the LLC will
have the right to undertake the opposition or defense of such claim in MMT's
name. In the event that the LLC undertakes the opposition or defense of such
claim, the LLC shall consult with MMT in connection with all material issues
relating to such opposition or defense and shall consult with MMT prior to
commencing the same and shall consider any recommendations by MMT with respect
to the conduct and settlement or compromise thereof and any reasonable
alternative resolutions of the MMT Infringement Claim. The LLC shall not settle
any MMT Infringement Claim without MMT's prior written consent. If the LLC
undertakes to oppose or defend any MMT Infringement Claim pursuant to the
procedures provided for in this Section 7.3, MMT shall bear all costs of such
action or proceeding and shall pay any judgment or settlement amount awarded or
obtained with respect to such MMT Infringement Claim.

      7.4. LLC Infringement Claims. In the event of any claim that any
combination by the LLC of any non-infringing MMT Licensed Property, or any
non-infringing equipment, material or process based on or utilizing MMT Licensed
Property, with any Intellectual Property not furnished by MMT or any claim that
the use by the LLC of the
<PAGE>   20
                                      -20-


MMT Licensed Property, or any equipment, material or process based on or
utilizing MMT Licensed Property, in a manner not contemplated by this Agreement
infringes, misappropriates, violates or dilutes any proprietary right or
property of any third Person (each a "LLC Infringement Claim"), then, subject to
Section 7.5 below, the LLC shall have the obligation to take all actions
reasonably necessary to oppose or defend such claims and to pay any judgment or
settlement amount awarded or obtained with respect to such LLC Infringement
Claim. In the course of opposing or defending any such LLC Infringement Claim,
the LLC shall consult with MMT in connection with all material issues relating
to such opposition or defense and shall consult with MMT prior to commencing the
same and shall consider any recommendations by MMT with respect to the conduct
and settlement or compromise thereof and any reasonable alternative resolutions
of the LLC Infringement Claim. In the event that the LLC does not undertake to
oppose or defend any such action within ninety (90) days after the LLC becomes
aware of such LLC Infringement Claim, MMT will have the right to undertake the
opposition or defense of such claim in the LLC's name. In the event that MMT
undertakes the opposition or defense of such claim, MMT shall consult with the
LLC in connection with all material issues relating to such opposition or
defense and shall consult with the LLC prior to commencing the same and shall
consider any recommendations by the LLC with respect to the conduct and
settlement or compromise thereof and any reasonable alternative resolutions of
the LLC Infringement Claim. MMT shall not settle any LLC Infringement Claim
without the LLC's prior written consent. If MMT undertakes to oppose or defend
any LLC Infringement Claim pursuant to the procedure provided for in this
Section 7.4, the LLC shall bear all costs of such action or proceeding and shall
pay any judgment or settlement amount awarded or obtained with respect to such
LLC Infringement Claim.

      7.5. Mixed Claims. In the event of any claim of infringement,
misappropriation, violation or dilution of any proprietary right or property of
any third Person based solely on the MMT Licensed Property, or any equipment,
material or process based on or utilizing MMT Licensed Property, such claim will
be treated as an MMT Infringement Claim and governed by the defense,
indemnification and other provisions of Section 7.3. In the event of any such
claim based solely on the combination by the LLC of any non-infringing MMT
Licensed Property, or any non-infringing equipment, material or process based on
or utilizing MMT Licensed Property, with any Intellectual Property not furnished
by MMT or any such claim based solely on the use by the LLC of the MMT Licensed
Property, or any equipment, material or process based on or utilizing MMT
Licensed Property, in a manner not contemplated by the applicable conceptual
design package approved by or at the direction of the Board of Directors of the
LLC with respect to the particular CEP Plant, such claim will be treated as a
LLC Infringement Claim and governed by the defense, indemnification and other
provisions of Section 7.4. In the event of any claim which combines elements of
both an MMT Infringement Claim and a LLC Infringement Claim, MMT and the LLC
shall defend such claim jointly, with the costs of such defense and any judgment
or settlement amount awarded or obtained to be shared between them based on the
damages

attributable to the MMT Infringement Claim versus the damages attributable to
the LLC Infringement Claim.

and in order to avoid multiple conveyances of assets from M4 to LMC and then

shall acquire and take assignment and delivery of, all of the assets of M4
relating to ReTech but excluding the Excluded Assets (as defined in Section 2.2)
(all of which assets are hereinafter referred to collectively as the "Acquired
Assets"), including, without limitation:

relating to ReTech, including, without limitation, those set forth on Schedule

            (e) all permits, approvals, certificates, franchises, licenses and

the Intellectual Property set forth on Schedule 2.1(f) hereto; and

            (g) all cash and cash equivalents relating to ReTech, including
without limitation the deposits listed on Schedule 2.1(g) hereto.

      2.2.  Excluded Assets.  Notwithstanding the foregoing, M4 is not
transferring and LMAES is not acquiring pursuant to this Agreement, and the
term "Acquired Assets" shall not include, any of the following assets
(collectively, the "Excluded Assets"):

            (a) any of M4's Intellectual Property relating to the ThermUHex

      2.3. Mixed Assets. In the event that any assets of M4 are used in
connection with ReTech and are also used in connection with any other business
of M4, then M4 and LMAES will discuss in good faith whether such assets are used
primarily in ReTech's business or primarily in such other business of M4 and
accordingly whether or not such assets should constitute Acquired Assets or
Excluded Assets for purposes of this Agreement. The foregoing sentence shall not
apply to any of the Excluded Assets identified in Section 2.2.

                                    Article 3

                    Assumption of Obligations; Termination of
                  Revolving Credit Agreement; Cash Adjustments

      3.1. Assumption of Obligations. Except as set forth on Schedule 3.1(a)
hereto, effective upon consummation of the Closing (as defined in Article 4),
LMAES hereby agrees to pay, perform, fulfill and discharge all obligations of M4
of any nature, known or unknown, fixed or contingent, relating to ReTech,
including, without limitation, any and all Assumed Liabilities as defined in the
Asset Acquisition Agreement (collectively, the Assumed Obligations") and those
liabilities listed on Schedule 3.1(b) hereto.

      3.2. Termination of Revolving Credit Agreement. As partial consideration
for the transfer of the Acquired Assets by M4 to LMAES, LMC agrees that,
effective upon the Closing, the Revolving Credit Agreement shall be considered
terminated for all purposes and all amounts owed thereunder shall be considered
paid in full.

      3.3.  Cash Adjustment.

            Prior to the Closing, representatives of M4 and LMC established the
fair market value of the Acquired Assets, net of the Assumed Liabilities, as of
the Closing Date (as defined in Article 4), to be $17,000,000 ("Net Transferred
Value"). In addition, these representatives determined that the Revolving Credit
Amount was $15,760,000. As the Net Transferred Value exceeds the Revolving
Credit Amount, LMC will pay cash to M4 at the Closing in the amount of
$1,240,000.

                                    Article 4

            (a) M4 shall duly execute and deliver to LMAES or its nominee or
nominees such deeds, certificates of title or other instruments of assignment
and transfer with respect to the Acquired Assets as LMC may reasonably request
and as may be necessary to vest in LMAES all of M4's title to and interest in
all of the Acquired Assets, in each case subject to no Encumbrance (as defined
in Section 5.3) except for the Encumbrances specified in Schedule 4.2(a) hereto
(the "Permitted Encumbrances"). These transfer instruments will include a Bill
of Sale and Assignment in the form of Exhibit A hereto, Patent Assignments in
the form of Exhibit B-1 and Exhibit B-2 hereto, and a Trademark Assignment in
the form of Exhibit C hereto.

            (b) M4 shall deliver or cause to be delivered to LMAES all of the
contracts and agreements of M4 included in the Acquired Assets, and all of the
business records, tax returns, books and other data of M4 relating to the

take such action as M4 deems reasonably appropriate to separate or redact
information unrelated to any of the Acquired Assets from business records, tax
returns, books and other data of M4 to be delivered to LMAES at the Closing
pursuant to this Section 4.2(b).

                                    Article 7

                     Certain Transitional and Other Matters

      7.1.  Nonassignable Contracts.

            (a) To the extent that any Assumed Contract is not capable of being
transferred by M4 to LMAES pursuant to this Agreement without the consent,
approval or waiver of a third Person, and such consent, approval or waiver 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,
nothing in this Agreement will constitute a transfer or an attempted transfer
thereof. Notwithstanding anything contained in this Agreement to the contrary,
M4 shall not be obligated to transfer to LMAES any of its rights and obligations
in and to any of the Assumed Contracts referred to in this Section 7.1 without
first having obtained any consents, approvals and waivers necessary for the
transfer of such Assumed Contract.

            (b) In the event that such consents, approvals and waivers referred
to in subparagraph (a) above are not obtained, then, in the case of any such
Assumed Contract, LMC, MMT, LMAES and M4 shall continue to cooperate and use
their best efforts to obtain the necessary consents, approvals and waivers (to
the extent that it is reasonably likely that such efforts will be successful),
and unless and until any such necessary consent, approval or waiver is obtained,
M4 will use its best reasonable efforts, to the extent permitted by applicable
law, the terms of the Assumed Contract and the directions of the customer, to
(a) cooperate in any reasonable arrangement designed to provide to LMAES the
benefits and burdens of any Assumed Contract referred to in subparagraph (a)
above without incurring any obligation to any other Person other than to provide
such benefits to LMAES, including, without limitation, the appointment of LMAES
as M4's agent for purposes of such Assumed Contract, and (b) enforce, at LMC's
and LMAES' request for LMAES' account and at LMAES' cost, any rights of M4
arising from any such Assumed Contract (including, without limitation, the right
to elect to terminate such Assumed Contract in accordance with the terms thereof
upon the advice of LMC or LMAES).

      7.2.  Hiring Employees and Related Matters.

            (a)(i) At the Closing, LMAES will offer employment to the employees
of M4 listed on Schedule 7.2(i) hereto at wages (excluding incentive
compensation programs) and benefits comparable in the aggregate to the wages and
benefits currently provided to such employees by M4. The employees accepting
such offer are referred to below as the "LMAES Assumed Employees." LMAES shall
have all responsibility for severance to any LMAES Assumed Employee. LMAES shall
recognize for each LMAES Assumed Employee who accepts an offer of employment and
commences work with LMAES service with M4 prior to the Closing Date under any
Welfare Benefit Plan (as defined in the Employee Retirement Security Act of
1974, as amended) maintained by LMAES to the extent such service was recognized
under a comparable M4 plan.

                                      -9-


            (ii) At the Closing, MMT will offer employment to the employees of
M4 listed on Schedule 7.2(ii) hereto at wages (excluding incentive compensation
programs) and benefits comparable in the aggregate to the wages and benefits
currently provided to such employees by M4. The employees accepting such offer
are referred to below as the "MMT Assumed Employees." MMT shall have all
responsibility for severance to any MMT Assumed Employee. MMT shall recognize
for each MMT Assumed Employee who accepts an offer of employment and commences
work with MMT service with M4 prior to the Closing Date under any Welfare
Benefit Plan (as defined in the Employee Retirement Security Act of 1974, as
amended) maintained by MMT to the extent such service was recognized under a
comparable M4 plan.

            (iii) After giving effect to the offers of employment referred to in
subparagraphs (i) and (ii) above, M4 will continue to employ those transitional
employees referred to in Exhibit 11 of the HR Plan. As provided in Exhibit 11 of
the HR Plan and Section 9.4 of the Restructuring Agreement, the cost of these
transitional employees will be shared equally by LMC and MMT.

            (b)(i) Nothing in this Agreement shall obligate LMAES to make any
offer of employment to anyone other than a LMAES Assumed Employee or, except as
provided in paragraph (c) below, to provide continued employment to any employee
of M4, whether or not the subject of an employment offer from LMAES, for any
specified period of time following the Closing Date, or to maintain the same
terms of employment (including, without limitation, compensation and benefits)
for any specified period of time following the Closing Date. LMAES will not be
obligated to offer employment to anyone other than the persons listed on
Schedule 7.2(i) hereto. Each LMAES Assumed Employee offered a position at LMAES
will be considered an employee at will whose employment may be terminated at any
time and for any reason.

            (ii) Nothing in this Agreement shall obligate MMT to make any offer
of employment to anyone other than an MMT Assumed Employee or, except as
provided in paragraph (c) below, to provide continued employment to any employee
of M4, whether or not the subject of an employment offer from MMT, for any
specified period of time following the Closing Date, or to maintain the same
terms of employment (including, without limitation, compensation and benefits)
for any specified period of time following the Closing Date. MMT will not be
obligated to offer employment to anyone other than the persons listed on
Schedule 7.2(ii) hereto. Each MMT Assumed Employee offered a position at MMT
will be considered an employee at will whose employment may be terminated at any
time and for any reason.

            (c) LMAES agrees that, for a period of 60 days after the Closing
Date, it will not cause any of the LMAES Assumed Employees hired by it to suffer
"employment loss," excluding any employment loss in connection with the
completion of a project as contemplated by 29 U.S.C. 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
<PAGE>   10
                                      -10-



employment loss could create any liability for M4, unless LMAES delivers notices
under the WARN Act in such a manner and at such a time that M4 bears no
liability with respect thereto. MMT agrees that, for a period of 60 days after
the Closing Date, it will not cause any of the MMT Assumed 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 M4
unless MMT delivers notices under the WARN Act in such a manner and at such a
time that M4 bears no liability with respect thereto.

            (d)(i) M4 agrees to provide reasonable cooperation to LMAES in
connection with the transition by the LMAES Assumed Employees and their
dependents and beneficiaries to the medical and dental benefits coverage offered
by LMAES. To the extent not prohibited by applicable laws or any confidentiality
obligations of M4, this cooperation will include the provision by M4 to LMAES or
LMAES' insurers of information regarding any pre-existing conditions of the
LMAES Assumed Employees or any of their dependents or beneficiaries.

            (ii) M4 agrees to provide reasonable cooperation to MMT in
connection with the transition by the MMT Assumed Employees and their dependents
and beneficiaries to the medical and dental benefits coverage offered by MMT. To
the extent not prohibited by applicable laws or any confidentiality obligations
of M4, this cooperation will include the provision by M4 to MMT or MMT's
insurers of information regarding any pre-existing conditions of the MMT Assumed
Employees or any of their dependents or beneficiaries.

            (e) Following the Closing, M4 shall remain the sponsor of the 401(k)
Savings Plan and the Capital Accumulation Plan (the "Frozen Plans") in which the
LMAES Assumed Employees and MMT Assumed Employees currently participate. No
further contributions will be made to the Frozen Plans with respect to service
on or after the Closing Date and no new participants will be added to the Frozen
Plans on or after the Closing Date. All participants shall become 100% vested in
their account balances as of the Closing Date. M4 shall take all actions
reasonably necessary, including amending the Frozen Plans, to obtain favorable
determination letters from the IRS for the Frozen Plans. Promptly following the
receipt of such favorable determination letters, the then existing account
balances in the Frozen Plans relating to LMAES Assumed Employees shall be
transferred in cash or in the form of the particular LMAES Assumed Employee's
promissory note(s) (evidencing loans to the particular LMAES Assumed Employee
under the Frozen Plans), to a qualified defined contribution plan (or plans)
designated by LMAES. The parties shall reasonably cooperate in connection with
administering loan repayments by participants to the Frozen Plans prior to the
transfer of account balances as described above. As soon as practicable
following the Closing, M4 shall designate a nationally recognized bank that is
acceptable to LMAES to serve as trustee of the Frozen Plans.

            (f) As contemplated by Section 9.4 of the Restructuring Agreement,
M4 will be responsible for the administration and winding up of its employee
benefit plans (including the Frozen Plans) until they are terminated. LMC and
MMT shall each be
<PAGE>   11
                                      -11-


responsible for one-half of M4's out-of-pocket costs incurred in connection with
the foregoing. M4 shall bear its own internal costs.

            (g) Except as expressly provided above in this Section 7.2,
responsibility between LMC and MMT regarding the employment by M4 of any of its
employees prior to the Closing Date and its benefit plans shall be allocated as
provided in Sections 8.3 and 9.4 of the Restructuring Agreement.

                                    Article 8

                                 Indemnification


      8.1. Indemnity by M4 and MMT. M4 and MMT jointly and severally hereby
agree to indemnify and hold LMC and LMAES and their respective Affiliates

      8.5.  Claims.

            (a) Notice. Any party seeking indemnification hereunder (the
"Indemnified Party") shall promptly notify the other party hereto (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 the Indemnifying Party of its obligations under this Article 8
except to the extent, if at all, that such Indemnifying Party shall have been
prejudiced thereby.

            (b) Third Party Claims. If a Claim relates to any action, suit,
proceeding or demand instituted against the Indemnified Party by a third party
(a "Third Party Claim"), the Indemnifying Party shall be entitled to participate
in the defense of such Third Party Claim after receipt of notice of such claim
from the Indemnified Party. Within thirty (30) days after receipt of notice of a
particular matter from the Indemnified Party, the Indemnifying Party may assume
the defense of such Third Party Claim, in which case the Indemnifying Party
shall have the authority to negotiate, compromise and settle such Third Party
Claim, if and only if the following conditions are satisfied:

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

                  (ii) the Indemnified Party shall not have given 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.

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.

      8.6. Method and Manner of Paying Claims. In the event of any Claims under
this Article 8, the claimant shall advise the party or parties who are required
to provide indemnification therefor in writing of the amount and circumstances
surrounding such claim. With respect to liquidated Claims, if within thirty (30)
days the other party has not contested such Claim in writing, the other party
will pay the full amount thereof within ten (10) days after the expiration of
such 30-day period. Any amount owed by an Indemnifying Party hereunder with
respect to any Claim may be set-off by the Indemnified Party against any amounts
owed by the Indemnified Party to any Indemnifying Party. The unpaid balance of a
Claim shall bear interest at a rate per annum equal to the lowest prime rate
published in the

Wall Street Journal in its "Money Rates" column on the date notice thereof is
given by the Indemnified Party to the Indemnifying Party.

                                  NEWS RELEASE

[Molten Metal Technology Letterhead]

FOR IMMEDIATE RELEASE

                   MOLTEN METAL FORMS NEW STRATEGIC ALLIANCE
                        WITH LOCKHEED MARTIN CORPORATION

                 COMPLETES RESTRUCTURING OF LIMITED PARTNERSHIP

WALTHAM, Massachusetts - June 18, 1997 - Molten Metal Technology, Inc.
(NASDAQ:MLTN) today announced completion of definitive agreements for a new
strategic alliance with Lockheed Martin Corporation (NYSE:LMT). The new
agreements are designed to enhance the ability of the corporations to more
efficiently access target markets.

The two corporations have established a strategic alliance committee, comprised
of three representatives from each corporation, to review and monitor the
business relationships created by the restructuring of the former M4
Environmental limited partnership. The strategic alliance committee will also
evaluate new market opportunities for joint efforts within the Department of
Energy (DOE) and Department of Defense markets.

The two corporations formed a new limited liability corporation (LLC) to
deliver processing services to customers in the worldwide chemical
demilitarization market. This LLC, Lockheed Martin Chemical Demilitarization
Systems, L.L.C., is an exclusive relationship that will enable the corporations
to pursue chemical demilitarization opportunities around the world.

In addition to the new LLC for the chemical demilitarization market, the two
companies will continue to work together on the DOE's Hanford tank waste
project. Under the new relationship, Molten Metal Technology will deliver a $5
million pilot Quantum-CEP(R) system to the Lockheed Martin team for processing
surrogate Hanford tank waste. Lockheed Martin leads one of two corporate teams
that recently won the first phase of a DOE bid to begin efforts toward the
cleanup of radioactive tank waste at the DOE site in Hanford, Washington. The
Quantum-CEP plant will support Lockheed Martin's efforts to use Quantum-CEP in
addition to or in place of its currently proposed baseline technology for the
second phase of the Hanford project. The DOE is scheduled to announce plans for
the second phase of the Hanford cleanup in 1998, an award estimated to be worth
several billion dollars.

As a part of the restructuring, the RETECH division of M4 that provides plasma
arc technology to the specialty metal and environmental industry has been
transferred to Lockheed Martin, while Molten Metal Technology has become sole
owner of M4, which will continue to own and operate its primary asset, the
Technology Center in Oak Ridge, Tennessee. The Center contains two commercial
Quantum-CEP systems. One of the commercial systems began operating in December
of 1995. The second and much larger system is currently in start-up operations
and is expected to begin commercial operations later this year.

Operation of the Technology Center through M4 should enable Molten Metal
Technology to continue to expand its presence in several key market sectors,
such as commercial mixed (radioactive and hazardous) waste.

Based in Waltham, Massachusetts, 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. The company's patented core technology,
CEP, takes waste and transforms it into reusable industrial products using a
molten metal bath. The first commercial Quantum-CEP plant constructed by the
company began operating in 1995. A second commercial Quantum-CEP plant is now
processing waste from commercial nuclear customers. A third commercial
Quantum-CEP facility is currently in the start-up phase. Quantum-CEP is the
application of CEP developed specifically to process radioactive waste. Two more
commercial CEP plants are under construction.

Certain statements contained in this press release regarding future events are
"forward-looking statements" within the meaning of the federal securities laws,
including statements concerning the company's expectations regarding the future
performance of its relationship with Lockheed Martin, the use of Quantum-CEP in
the Hanford cleanup project, future operations at the M4 Technology Center, and
the construction and start-up of CEP facilities. These forward-looking
statements are based largely on Molten Metal Technology's expectations and are
subject to a number of risks and uncertainties, many of which are beyond the
company's control. Accordingly, actual results could differ materially from
those contemplated by these forward-looking statements. Among the risks and
uncertainties which could affect actual results are that potential customers
will not accept the company's CEP technology as an economically and
environmentally acceptable means of disposing of wastes and by-products; that
the company will be unable to build its CEP plants on time and under budget; and
that the company will not be able to commercially operate CEP plants on a
sustained and profitable basis. Additional factors which may cause actual
results to differ are described in the company's Annual Report on Form 10-K for
the year ended December 31, 1996, as well as the company's other filings with
the Securities and Exchange Commission and are incorporated herein by reference.
