                 MOLTEN METAL TECHNOLOGY, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. BASIS OF PRESENTATION

Molten Metal Technology, Inc. (the "Company") 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 developed its core technology, Catalytic
Extraction Processing ("CEP"), to dissolve waste compounds to their constituent
elements in a molten metal bath and reconfigure the elements into useful raw
materials.

The consolidated financial statements include the accounts of the Company and
its wholly owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation.

Net income (loss) per share is determined by dividing net income (loss) by the
weighted average number of common and common equivalent shares outstanding
during the period. Common share equivalents consist of common stock which may be
issuable upon exercise of outstanding stock options and warrants. Common share
equivalents have been excluded from the weighted average number of common shares
in loss periods since their effect is anti-dilutive.

Certain reclassifications have been made for consistent presentation. The
reclassifications have no effect on the net loss for the periods ending June 30,
1995.

The information furnished is unaudited and reflects all adjustments (consisting
of only normal recurring adjustments) which, in the opinion of management, are
necessary for a fair presentation of the financial position and results of
operations for the interim periods. The accompanying financial statements should
be read in conjunction with the Company's audited financial statements and
related footnotes for the year ended December 31, 1995 which are included in the
Company's annual report on Form 10-K for the year ended December 31, 1995. The
results of operations for the periods ended June 30, 1996 are not necessarily
indicative of the results to be expected for the full year.

NOTE 2. EQUITY TRANSACTIONS

During the quarter ended June 30, 1996, 94,351 shares of common stock were
issued upon the exercise of options.

In April 1996, the Company and Lockheed Martin Corporation("LMC") closed an
agreement to expand their partnership (M4 Environmental L.P. or "M4") through
the acquisition by M4 of the Retech division of Lockheed Environmental Systems &
Technologies Co., an indirect wholly-owned subsidiary of LMC. The Retech
division designs and manufactures metallurgical equipment and waste processing


                                       6
<PAGE>   7

systems that utilize a plasma technology. Under this agreement, LMC contributed
approximately half of the assets of the Retech division to M4, and the Company
purchased substantially all of the remaining assets of the Retech division for
307,735 shares of its common stock, and then immediately contributed these
assets to M4. Pursuant to the agreement, the number of shares issued to LMC will
be adjusted when the value of net contributions from LMC to Retech is
determined.

NOTE 3. CONVERTIBLE DEBT

In May 1996, the Company issued $143,750,000 of Convertible Subordinated Notes
Due 2006 (the "Notes"). The Notes have a term of ten years and are payable in
full on May 1, 2006. The Notes bear interest at the rate of 5.50% per year
payable semi-annually. The Notes are convertible into shares of the Company's
common stock at a conversion price of $38.75 per share.

</TABLE>


The increases in engineering and construction revenue are due to the development
of CEP systems for M4 as the Company continues to escalate commercial
activities. R&D and consulting revenue increased from 1995 due to billings under
various development contracts with M4. Technology transfer and success fees
increased in 1996 as a result of the recognition of plant start-up fees from M4.
Under the terms of the partnership agreement with M4, the Company was entitled
to a fee of $2,000,000 upon the start-up of each of the first three CEP plants
developed by M4. As of June 30, 1996, the Company has earned each of these three
start-up fees. The existence and timing of the Company's commercial sales and
operations and related revenue will depend on a number of factors, including the
ability of the Company and its affiliates to successfully market, permit and
build CEP systems on a timely basis for their target markets, and no assurances
can be made in this regard.

Cost of revenues for the second quarter of 1996 increased to $14,395,000 from
$5,623,000 in the second quarter of 1995 and increased to $30,718,000 for the
first half of 1996 from $8,517,000 for the first half of 1995. The increases are
primarily attributable to an increase in engineering and construction activities
in connection with the development of CEP systems for M4.

R&D expenses for the second quarter of 1996 increased to $4,619,000 from
$2,206,000 

                                       8
<PAGE>   9

in the second quarter of 1995 and increased to $9,327,000 for the first half of
1996 from $5,894,000 for the first half of 1995. The increases reflect an
increase in costs associated with the continued development of CEP and the
performance of internally funded CEP demonstrations. SG&A expenses for the
second quarter of 1996 increased to $2,211,000 from $1,137,000 in the second
quarter of 1995 and increased to $4,629,000 for the first half of 1996 from
$3,078,000 for the first half of 1995. The increase reflects the hiring of
additional personnel and the expansion of corporate infrastructure. The Company
anticipates that total expenses will continue to increase as commercial
activities escalate. The classification of expenses between cost of revenue, R&D
and SG&A will depend on the number and amount of future cost reimbursement
contracts and the related absorption of R&D and SG&A expenses into cost of
revenue.

The Company accounts for its investment in M4 using the equity method. Equity
income from M4 for the second quarter of 1996 increased to $2,307,000 from
$183,000 in the second quarter of 1995 and increased to $2,676,000 for the first
half of 1996 from $183,000 for the first half of 1995 reflecting the Company's
share of revenue earned by M4. The increases in 1996 are due to an increase in
M4 revenue resulting from the inclusion of the Retech division's operations
subsequent to the acquisition in April 1996. Under the partnership agreement, 
the Company and LMC share equally in M4's revenues and all expenses are 
allocated to LMC until the capital accounts of the Company and LMC are equal. 
Thereafter, the Company and LMC will share equally in the profits or losses of
M4. The Company anticipates that its capital account will become equal to LMC's
capital account within one year. The related effect on the Company's equity in
earnings of M4 could have a material adverse effect on future results of 
operations.

Interest income for the second quarter of 1996 increased to $2,231,000 from
$1,380,000 in the second quarter of 1995 and increased to $3,585,000 for the
first half of 1996 from $2,752,000 for the first half of 1995. The increases are
due to interest earned on the net proceeds from the issuance of convertible debt
in May 1996. Interest expense for the second quarter of 1996 increased to
$1,675,000 from $436,000 in the second quarter of 1995 and increased to
$2,108,000 for the first half of 1996 from $915,000 for the first half of 1995.
The increases are due to interest on the convertible debt issued in May 1996.

FINANCIAL CONDITION

As of June 30, 1996, the Company's cash, cash equivalents and short-term
investments increased by approximately $110,006,000 from December 31, 1995. The
increase was primarily a result of the net proceeds from the issuance of
convertible debt. The increase was offset by cash used in operations and for the
acquisition of fixed assets. For the remainder of 1996, the Company expects to
incur significant additional expenditures related to the engineering,
construction and start-up of commercial CEP systems owned by itself and through
joint ventures. The Company intends to seek debt financing to finance or
re-finance a substantial portion of these 


                                       9
<PAGE>   10

expenditures. The amount, timing and effect on liquidity of capital
expenditures, including equity contributions to joint ventures, to be made by
the Company in connection with the development of commercial CEP systems will
depend on a number of factors, including the number of systems to be developed,
the timing of the development of such CEP systems, the terms of the development
arrangements with the Company's customers and partners and the extent to which
the Company is able to obtain financing for such CEP systems.

As of June 30, 1996, accounts receivable and accounts receivable from affiliate
increased by approximately $16,230,000 from December 31, 1995 due to amounts
earned under contracts with M4 and the United States Department of Energy. As of
June 30, 1996, total accounts receivable were $33,561,000. Of this amount,
$15,300,000 was unbilled at June 30, 1996 and approximately $3,115,000 was 
collected subsequent to June 30, 1996.

During 1996, the Company earned revenue from M4 relating to services provided
for the engineering and construction of CEP systems and from fees earned for the
successful start-up of CEP systems. For items that are capitalized by M4, the
portion of the gross profit representing the Company's ownership interest
related to such revenue has been deferred, and will be recognized over the
period that the related assets are depreciated by M4. As of June 30, 1996, the
related deferred income increased by $2,145,000 from December 31, 1995 due to
billings under construction contracts with M4.

Certain statements contained in this Form 10-Q regarding future events or the
future financial performance of the Company are forward-looking statements
within the meaning of the federal securities laws. These statements are only
predictions and actual events or results may differ materially as a result of
various factors, including compliance with regulatory requirements, obtaining
required permits, customer acceptance of the Company's technology, successful
negotiation of customer contracts, obtaining required funding, and competition.
Additional factors which may cause actual results to differ are described in the
Company's filings with the Securities and Exchange Commission, including the
Form 8-K filed by the Company on July 3, 1996.

               (1) to its directors, officers and employees who have a
          reasonable need to know the contents thereof and who are subject to a
          written confidentiality agreement with UHDE obligating them to keep
          confidential the MMT Confidential Information, subject to customary
          exceptions similar to those set forth in paragraphs (a) above and
          (b)(4) below;

               (2) on a confidential basis to those Advisors of UHDE who have a
          reasonable need to know the contents thereof, so long as such
          disclosure is made pursuant to the procedures referred to in Section
          7.4(b);

               (3) to existing and prospective customers, vendors and
          institutional financing sources who have a reasonable need to know the
          contents thereof in connection with the activities contemplated by
          this Agreement if such disclosure is made pursuant to the procedures
          referred to in Section 7.4(b); and

               (4) to the extent required by applicable statute, rule or
          regulation or any court of competent jurisdiction; provided that UHDE
          has made reasonable efforts to conduct its relevant business
          activities in a manner such that the disclosure requirements of such
          statute, rule or regulation or court of competent jurisdiction do not
          apply, and provided further that MMT is given notice and an adequate
          opportunity to contest such disclosure or to use any means available
          to minimize such disclosure.

     7.3  DISCLOSURE TO GOVERNMENT AUTHORITIES. UHDE and MMT shall promptly
establish and implement all procedural safeguards required or advisable in
connection with the performance of government contracts or other disclosure to
government authorities to protect the confidentiality and value of the UHDE
Confidential Information and the MMT Confidential Information.

     7.4  Ongoing Confidentiality Program.
          -------------------------------

               (a) In order to ensure that MMT and UHDE comply with their
obligations in Sections 7.1 through 7.3, the Steering Committee together with
any advising attorneys shall meet as required to discuss issues relating to
confidentiality and disclosure and other matters addressed by this Article 7.

               (b) With respect to any disclosure by MMT or UHDE to any of its
Advisors pursuant to Sections 7.l(b)(2) or Section 7.2(b)(2) or by MMT or UHDE
to any existing or prospective customers, vendors, or institutional financing
sources pursuant to Section 7.1(b)(3) or Section 7.2(b)(3), the Steering
Committee will institute procedures 

                                       9
<PAGE>   10

designed to maintain the confidentiality of UHDE Confidential Information and
MMT Confidential Information while facilitating the business activities
contemplated by this Agreement. These procedures shall include the preparation
of standard forms of confidentiality agreements to be used by UHDE and MMT in
connection with such disclosures.

     7.5 THIRD PARTY INFORMATION. MMT and UHDE agree that nothing in this
Agreement shall be deemed to obligate either one of them to disclose UHDE
Confidential Information or MMT Confidential Information in violation of a
confidentiality obligation owed by the party possessing such information. In the
event that UHDE discloses UHDE Confidential Information to MMT, or MMT discloses
MMT Confidential Information to UHDE, in violation of a confidentiality
obligation owed to a third party by the disclosing party, the recipient shall,
without limiting its other obligations under this Article 7, upon request return
to the disclosing party all copies of such confidential information in any
tangible form.

     7.6 TERM OF CONFIDENTIALITY OBLIGATIONS. The restrictions created by this
Article 7 shall continue for a period of ten (10) years after any termination of

     8.1 ESTABLISHMENT OF STEERING COMMITTEE. The parties shall establish a
steering committee (the "Steering Committee") for purposes of monitoring the

improvements and inventions relating to CEP Core Technology and resulting from
the efforts of either of the parties, or jointly from the efforts of both
parties, under this Agreement, or any other agreement or undertaking between the
parties in connection herewith shall be the sole and exclusive property of MMT.
While the parties acknowledge that such intellectual property will be owned by
MMT, MMT will give due consideration, subject to the particular circumstances,
for UHDE to be involved in performance of engineering services where any such
intellectual property which was developed solely by UHDE, or jointly by UHDE and
MMT, is commercially deployed.

               (b)

or inventions conceived by UHDE, whether alone or jointly with MMT, to which MMT
has rights under clause (a) or (b) above.

Each party agrees to give the other all reasonable assistance in obtaining
patent, copyright or other protection and in preparing and prosecuting any
patent application or copyright application filed by the other, and each party
will cause to be executed all assignments and other instruments and documents as
the other party may consider reasonably necessary or appropriate to carry out
the intent of this Section 9.2(c). Each party shall be responsible for its own
costs associated with obtaining and maintaining any such intellectual property
protection.

               (d) MMT shall be solely responsible for all decisions relating to
seeking or maintaining patent or copyright or other protection for any
intellectual property or invention conceived under clause (a) above, and shall
be responsible for obtaining and maintaining any such protection. If MMT is
unable, after reasonable effort, to secure UHDE's signature of any patent,
copyright or other protection relating to any such intellectual property or
invention for any reason whatsoever, UHDE hereby irrevocably designates and
appoints MMT and its duly authorized officers and agents as UHDE's
attorney-in-fact, to act for and in UHDE's behalf and stead to execute and file
any such application or applications and to do all other lawfully permitted acts
to further the prosecution and issuance of patent, copyright or other protection
thereon with the same legal force and effect as if executed by UHDE.

performance is affected by the Force Majeure Event to the extent so affected
provided that:

               (a) the nonperforming party, as promptly as possible after it

               (d) Unless otherwise agreed to in writing by MMT, this Agreement
shall automatically terminate upon written notice by MMT if on any anniversary
date UHDE has not met the Minimum Requirement for the preceding one-year period.

     13.3 WAIVER OF TERMINATION CLAIMS. Termination of this Agreement by either
party will not impose upon that party any liability to the other party for
compensation, reimbursement or damage either on account of present or
prospective profits on sales or anticipated sales, or on account of
expenditures, investments or commitments made in connection therewith or in
connection of the business or goodwill of the other party, or on account of any
other cause or thing whatsoever, and any and all claims of such liability and
right to make such claims are hereby waived by the other party; provided,

acknowledges that the other party (the "non-breaching party") will suffer
irreparable harm in the event of a breach of the breaching party's obligations
under Article 7 or Article 9, and that monetary damages will be inadequate to
compensate for such breach. Accordingly, in addition to its other rights or
remedies, the non-breaching party will be entitled to injunctive relief in order
to restrain any such breach by the breaching party or its agents or employees.
The prevailing party shall be entitled to recover its costs, including attorneys
fees, incurred in enforcing such Articles of this Agreement.

     5.1. Teaming.
          -------

     (a)  In the interest of serving the needs of both the Partnership and LMC
          and their major customers, LMC (through LMC/EES) and the Partnership
          agree to enter into teaming arrangements in response to certain DOE,
          DoD and USEC government procurement opportunities requiring Treatment
          or Recycling of Feedstocks or other waste, in particular for contracts
          that require financial commitments in excess of a pre-determined
          threshold. Any contract opportunity that becomes the subject of this
          teaming 


<PAGE>   13
                                      -13-

          arrangement is referred to below as a "TEAMED PROJECT". Any such
          teaming arrangements will be on the basis contemplated by Section
          5.1(c).

     (b)  For purposes of determining which DOE, DoD or USEC requests for
          proposal ("RFP's") shall constitute Teamed Projects, LMC and the
          Partnership will be guided by an analysis of the Partnership's current
          Business Plan, with respect to which the parties have agreed that

                              *     will be designated as Teamed Projects
          for purposes of this Section 5.1. From these projects LMC and the
          Partnership will extrapolate the characteristics necessary to
          determine the threshold for future projects to become Teamed Projects.
          These criteria will also take into account the Partnership's expected
          growth and financial strength and operating experience.

     (c)  With respect to any Teamed Project, LMC will serve as the prime
          contractor, with overall contract and customer interface
          responsibility, and will provide general systems integration and
          program management, and the systems engineering and integration lead.
          The Partnership will be responsible for, and will provide (or
          subcontract for) and manage, all waste processing technologies
          necessary to perform the Teamed Project. For each RFP governed by this
          teaming arrangement, LMC and the Partnership will form an RFP response
          team staffed by both LMC and the Partnership, with one team leader
          from LMC and a deputy team leader from the Partnership. LMC and the
          Partnership, operating through this team, will promptly by joint
          agreement resolve all issues relating to the RFP, including system
          architecture, process design, facility design and construction,
          business and finance plans, selection of teammates and other matters
          necessary to respond effectively to the RFP. LMC and M4 will also
          establish their respective economic participation with respect to the
          applicable Teamed Project. If the necessary waste processing
          technologies are not already owned or controlled by the Partnership,
          it will obtain access to them for purpose of performing the applicable
          Teamed Project.

     (d)  The parties by mutual agreement may elect to vary the arrangement
          described above, on a case-by-case basis, depending upon the
          particular circumstances of the applicable RFP. In addition, when in
          the best interest of the Partnership and LMC/EES, as determined by
          each of the Partnership and LMC in its discretion, the Executive
          Committee and LMC can always, on a case-by-case basis, elect to enter
          into a teaming arrangement for RFP's that are below the applicable
          threshold or for procurement

          opportunities requiring waste processing anywhere in the world that
          are outside of the Market.

     (e)  Any dispute relating to the roles of LMC and the Partnership with
          respect to any proposed Teamed Project which cannot be resolved by the
          respective management teams will be directed to the Chairman of the
          Partnership and the President of LMC/EES. If the President of LMC/EES
          and the Chairman of the Partnership fail to resolve such dispute, LMC
          and the Partnership will not proceed with such Teamed Project, either
          alone or with others.

     (f)  The provisions of this Section 5.1 shall not prohibit LMC and its
          Subsidiaries from pursuing GOCO and similar opportunities or other
          business opportunities, including but not limited to areas involving
          environmental services, such as systems integration, remediation
          management, environmental consulting, analytical labs and waste
          characterization and transportation, in each case to the extent
          permitted under Section 7.3.

     5.2. Pit 9 Contract.
          --------------

     (a)  LMC (either directly or through a Subsidiary) will continue to perform
          the Pit 9 Contract generally within its current scope. LMC and the
          Partnership will agree on terms whereby the Partnership will assume
          (subject to obtaining any necessary customer approvals), by
          sub-contract, operational responsibility at a defined time
          (anticipated to be as soon as possible following the Limited Product
          Test and Operations Readiness Review milestones under the Pit 9
          Contract). LMC and the Partnership shall begin discussions with
          respect to this subcontract in advance of such milestones. This
          subcontract will provide that the Partnership will be appropriately
          compensated and will accept appropriate contractual responsibilities.

     (b)  After the earlier of the completion of the Pit 9 Contract or the
          occurrence of any material addition to or enhancement of the Pit 9
          Contract (the "OFFER TRIGGER DATE"), the infrastructure relating to
          the Pit 9 Contract and additional future business opportunities
          generated by the Pit 9 Contract, including the assets and liabilities,
          will be offered (subject to obtaining any necessary customer
          approvals) by LMC to the Partnership

                        *      pursuant to the procedures contemplated by 
          Section 7.3(d), except that LMC shall make such offer within fifteen
          (15) days after the Offer Trigger Date, the Partnership shall have
          fifteen (15)

          days after receipt of such offer to accept or reject such offer, and
          LMC and the Partnership shall work diligently to close such
          acquisition as soon as possible.

                                   ----------

        6.1. PRINCIPAL BUSINESS. The Partnership's principal business will be to
own, operate and sub-license waste processing technologies that contribute to
the development of a long term, high margin business. The Partnership's primary
technology base will be CEP, used in accordance with the MMT License Agreement,
for the Market and, following the acquisition contemplated by the Asset
Acquisition Agreement, Retech Technology for use in the Market and other
opportunities in any other market anywhere in the world as determined by the
Executive Committee. The best technology available to the Partnership shall be
used for any particular Partnership project taking into account both qualitative
and quantitative factors as determined by the Executive Committee exercising its
business judgment.

     6.2. Establishment.
          -------------

     (a)  LMC (as successor under the Master Agreement to MMC) and MMT have
          established an executive committee of the General Partner to implement
          this Agreement and the Related Agreements (the "EXECUTIVE COMMITTEE").
          The Executive Committee will oversee the development of the
          Partnership and the General Partner. The Executive Committee shall
          also serve as the Board of Directors of the General Partner. The
          Executive Committee shall be staffed by an equal number of senior
          representatives designated by LMC and MMT ("INSIDE DIRECTORS"), unless
          LMC and MMT mutually agree to select additional members not affiliated
          with LMC or MMT ("OUTSIDE DIRECTORS"). Unless LMC and MMT agree
          otherwise, the Executive Committee shall consist of a total of eight
          (8) members. Each Inside Director shall serve at the pleasure of the
          party which designated such Inside Director and may from time to time
          be replaced by such party. Any such replacement must be a member of
          senior management of the designating party. All Outside Directors may
          be replaced only with the mutual consent of LMC and MMT. Each party
          shall notify the other party in writing of the persons designated by
          it to serve on the Executive Committee as Inside Director and any
          replacement for such person promptly following such designation or
          replacement.

     (b)  The Chairman of the Executive Committee shall be a senior MMT
          executive designated from time to time by MMT. The Chairman shall
          preside at all meetings of the Executive Committee and shall have such




<PAGE>   16
                                      -16-


          other duties and responsibilities as are assigned from time to time by
          the Executive Committee.

     6.3. Authority and Duties.
          --------------------

     (a)  The Executive Committee shall have the specific authority delegated to
          it pursuant to this Agreement and the Related Agreements.

     (b)  DUTIES OF EXECUTIVE COMMITTEE. Without limiting the general duties and
          authority of the Executive Committee as set forth in this Article 6,
          the Executive Committee shall have responsibility for the evaluation
          of the performance of the General Manager, the establishment and
          monitoring of capital and operating budgets and other duties
          traditionally associated with Boards of Directors of Delaware
          corporations. The Executive Committee shall also review the Business
          Plan at least annually, and revise it as appropriate to reflect the
          business conditions and prospects for the Partnership. The Executive
          Committee shall form a compensation committee, over which the Chairman
          of the Executive Committee shall preside, to evaluate and set the
          compensation of the General Manager and other senior management.

     (c)  FIDUCIARY DUTIES. Each member of the Executive Committee shall have
          the fiduciary duties of loyalty and care (similar to fiduciary duties
          of loyalty and care of directors of a business corporation governed by
          the General Corporation Law of the State of Delaware) to the
          Partnership and all of the Limited Partners.

     6.4. MEETINGS. The Executive Committee will meet as often as the members
deem necessary, presently contemplated to be four times per year. Meetings may
be conducted in person or by telephone or in any other manner agreed to by the
Executive Committee. Either party may call a meeting of the Executive Committee
upon reasonable prior notice. No notice of a meeting shall be necessary when all
members of the Executive Committee are present. An equal number of Inside
Directors then designated by each party shall constitute a quorum. Meetings of
the Executive Committee may be attended by other representatives of LMC and MMT
and other persons related to the Partnership all as agreed to from time to time
by the Executive Committee. The Executive Committee will set up procedures
relating to the recording of minutes of its meetings. Actions of the Executive
Committee may also be taken without a meeting by unanimous written consent of
the Executive Committee in the manner permitted by Section 141(f) of the General
Corporation Law of the State of Delaware.

     6.5. POSITION OF GENERAL MANAGEr. LMC designated the President of the
General Partner as the general manager of the Partnership (the "GENERAL
MANAGER") to manage activities related to the development and operation of the
Partnership. The General Manager was, immediately prior to becoming the General
Manager, an employee of MMC, and may be removed from office only with the prior
agreement of the MMT




<PAGE>   17

                                      -17-

and LMC Directors, except that if either the MMT Directors or the LMC Directors
have objected to the Executive Committee on at least three separate occasions
about the General Manager's performance, providing information about the grounds
for such objections in reasonable detail, then upon the request of the objecting
party the LMC Directors and MMT Directors shall remove the General Manager and
select a mutually acceptable new General Manager. Upon the retirement or removal
of the General Manager, LMC may designate the replacement General Manager,
subject to the approval of the MMT Directors. LMC agrees that management of the
Partnership and the General Partner shall be the General Manager's only
responsibility and such General Manager's activities shall be directed solely
for the benefit of the Partnership and the General Partner.

     6.6. DUTIES OF GENERAL MANAGER. The General Manager shall be the Chief
Executive Officer of the General Partner and shall be responsible for the
management, operations, direction and administration of the Partnership and the
General Partner and shall have such other duties and responsibilities related to
the development of the Partnership as the Executive Committee shall from time to
time direct. Subject to the provisions of this Agreement and the Related
Agreements, the General Manager shall have discretion in choosing the remainder
of the management team for the Partnership. The General Manager shall be
responsible for advising the Executive Committee on the status of the
Partnership on a regular basis or more frequently as requested by the Executive
Committee.

                                    ---------

                     Exclusivity; Additional Market Segments
                     ---------------------------------------

     7.1. Exclusive Market Obligation of MMT.
          ----------------------------------

     (a)  MMT agrees that, during the term of this Agreement, except pursuant to
          this Agreement and other Related Agreements it shall not either
          directly or indirectly (whether through its Affiliates, as a
          shareholder, partner, or consultant):

          (i)  except to the extent permitted under paragraphs (b), (c), (d) or
               (e) below, own or operate any CEP Plant that processes any Market
               Feedstocks; or

          (ii) except to the extent permitted under paragraphs (b), (c), (d) or
               (e) below, sell or license any CEP Plant pursuant to sale or
               license terms which permit such CEP Plant to process any Market
               Feedstocks.

     (b)  Notwithstanding the provisions of paragraph (a) above, under
          relationships existing as of July 1, 1994




<PAGE>   18


          * or their successors in interest, * and MMT (solely to the extent it
          is acting together with * pursuant to either such relationship) may
          own and operate CEP Plants located in the United States that process
          Market Feedstocks generated in the United States, excluding, however,
          Radioactive or Mixed Market Feedstocks, which may not be processed by
          * or MMT pursuant to this paragraph (b). MMT shall determine annually
          the quantity of any such Feedstocks so processed. As provided in the
          MMT License Agreement, the Partnership and its sublicensees shall be
          allowed to process, at CEP Plants owned by the Partnership or its
          sublicensees and located in the United States, an amount of Hazardous,
          Toxic or Superfund Feedstocks, other than Limited Feedstocks, that are
          generated in the United States but which are not Market Feedstocks,
          equal to the amount of such Market Feedstocks so processed by * or
          MMT. Any CEP Plants developed by * or MMT, or their successors in
          interest, beyond the scope of the relationships existing as of July 1,
          1994 between MMT and * shall not qualify for the exemption provided by
          this paragraph (b) but instead shall be subject to the provisions of
          paragraph (c) below. MMT has previously disclosed in a writing
          acknowledged by MMC the nature of MMT's relationships with * .

     (c)  Except for any agreement entered into with * or their Subsidiaries
          consistent with the provisions of paragraph (b) above, no agreement
          entered into after July 1, 1994 by MMT with any Person other than the
          Partnership shall permit the applicable licensee to process any Market
          Feedstocks at the CEP Plant to be developed pursuant to such
          agreement. However, to provide some flexibility for unintended
          processing of Market Feedstocks, LMC agrees that if any such licensee
          processes Market Feedstocks, generated in the United States, at a CEP
          Plant located in the United States and developed pursuant to such
          agreement, in an amount * such action will not be considered a breach
          of such agreement. Correspondingly, MMT agrees that, as provided in
          the MMT License Agreement, if the Partnership processes Superfund,
          Hazardous or Toxic Feedstocks generated in the United States, other
          than Market Feedstocks or Limited Feedstocks, at any CEP Plant within
          the United States in an amount * such action shall not be considered a
          breach of the MMT License Agreement.

                                      -19-

     (d)  As provided in the MMT License Agreement, in the event that the
          environmental remediation or other similar responsibility of any
          governmental organization other than DoD, DOE or USEC, or any private
          entity, is transferred to or assumed by DoD, DOE or USEC (such as the
          DoD's Army Corps of Engineers assuming responsibility for remediation
          of Superfund sites otherwise under the jurisdiction of the EPA or a
          private entity), any Feedstocks nominally subject to or related to
          such responsibility shall not constitute "Market Feedstocks" for
          purposes of this Agreement and the Related Agreements. Accordingly,
          the Partnership and its sublicensees shall not be entitled to process
          any such Feedstocks and this Section 7.1 shall not prevent MMT and its
          licensees from processing any such Feedstocks. Subject to any
          restrictions imposed by MMT's current or future agreements with third
          parties, in the event DoD, DOE or USEC is assigned or assumes
          environmental remediation or similar responsibility from a government
          agency with respect to all of such government agency's facilities or
          otherwise assumes all of the environmental remediation or similar
          responsibility of such government agency, MMT shall give the
          Partnership a right of first offer, pursuant to terms and procedures
          equivalent to those in Section 7.2, with respect to any such
          Feedstocks.

     (e)  As provided in the MMT License Agreement, to the extent that the
          environmental remediation or other similar responsibility currently
          under the control of DoD, DOE or USEC is assigned to or assumed by any
          other government agency (a "SUCCESSOR AGENCY"), then the Partnership
          and its sublicensees shall be permitted to process the same type of
          Feedstocks with respect to such Successor Agency as those which the
          Partnership and its sublicensees could process with respect to DoD,
          DOE or USEC, as applicable, prior to such transfer to the Successor
          Agency, and MMT's restrictions under this Section 7.1 shall be
          extended in the same manner to such Successor Agency. The Executive
          Committee shall meet as required to discuss the effects of any change
          contemplated by this paragraph (e), and shall agree upon any changes
          required to this Agreement or the Related Agreements to reflect such
          change.

     (f)  The provisions of this Section 7.1 shall not restrict MMT and its
          licensees from owning, operating, selling, or licensing any CEP Plant
          processing Market Feedstocks to the extent such CEP Plant is developed
          by MMT or its licensees pursuant to Section 8(b).

     7.2. Additional Market Segments.
          --------------------------

     (a)  In addition to MMT's obligation under Section 7.1 with respect to DoD,
          DOE or USEC facilities, MMT agrees that, during the term of this
          Agreement, except pursuant to this Agreement and the Related
          Agreements it shall not grant a license to any third party to operate
          CEP 



<PAGE>   20

                                      -20-


          Plants serving all facilities under the sole control of any other
          United States federal government agency or authority (the "ADDITIONAL
          MARKET SEGMENTS"), without first offering such opportunity to the
          Partnership pursuant to this Section 7.2. An example of an Additional
          Market Segment would be a proposed license to a third party for CEP
          Plants serving all Department of Agriculture facilities.

     (b)  If MMT wishes to grant a license to a third party as provided in
          paragraph (a) above, it shall provide notice to the Executive
          Committee together with sufficient information to enable the Executive
          Committee to decide whether it wishes to pursue such opportunity
          through the Partnership. MMT shall not be required to have identified
          any particular third party or to have received an offer prior to
          implementing the procedures contemplated by this Section 7.2. The
          Executive Committee shall make its decision as promptly as practicable
          after receipt of such information, but in no event more than sixty
          (60) days after receipt of MMT's first notice, and provide prompt
          written notice of such decision to MMT.

          If the Executive Committee decides that it does not wish to pursue
          such opportunity through the Partnership, MMT shall thereafter be free
          to pursue such opportunity on its own. If the Executive Committee
          decides that it does wish to pursue such opportunity through the
          Partnership, the Partnership and MMT shall negotiate in good faith for
          thirty (30) days and if MMT and the Partnership are able to reach
          agreement within such period on the terms pursuant to which MMT shall
          permit the Partnership to pursue such opportunity, then MMT shall not
          pursue such opportunity outside the Partnership. If, after such
          decision, the Executive Committee decides not to pursue such
          opportunity any further, it shall provide prompt notice thereof to
          MMT, who shall thereafter be free to pursue such opportunity on its
          own outside the Partnership.

     (c)  Notwithstanding the foregoing, if additional capital is required from
          LMC in order for the Partnership to pursue any particular Additional
          Market Segment, such decision to pursue the Additional Market Segment
          shall be made by LMC as opposed to the Executive Committee.

     (d)  Any information disclosed by MMT to the Executive Committee pursuant
          to this Section 7.2 shall be subject to Section 6.2 of the MMT License
          Agreement.

          term of this Agreement and thereafter for the Designated Period,

                                    ---------

                                   OCI Issues
                                   ----------

     (a)  LMC and MMT acknowledge that insofar as LMC or its Affiliates have
          existing or future contracts with certain facilities constituting part
          of the Market, so-called "Organizational Conflict of Interest" ("OCI")
          issues could arise in connection with the transactions contemplated by
          this Agreement and the Related Agreements. The Executive Committee, or
          a sub-committee created by the Executive Committee and charged with
          overseeing such matters, shall meet regularly to discuss OCI issues,
          to act proactively to insure that OCI issues will have as little
          impact as possible on the Partnership's marketing and
          commercialization efforts, and to address and minimize the effect of
          any OCI issues that do arise.

     (b)  In the event that the Partnership intends to bid on or otherwise
          pursue any particular contract for a CEP Plant serving the Market, LMC
          will keep MMT informed about any possible OCI issues. LMC shall take
          all reasonable actions required to resolve or mitigate the particular
          OCI issues. MMT, if requested by LMC, shall assist LMC in resolving
          OCI issues. If, despite such actions, the applicable contracting
          officer determines that the Partnership will be precluded from bidding
          on such CEP Plant because of OCI issues, MMT shall be permitted to
          effectively bid for or accept the contract relating to such CEP Plant
          and otherwise shall be free, without compensation to the Partnership,
          to pursue such opportunity on its own or grant a license to a third
          party with respect to such opportunity. LMC agrees to cooperate with
          MMT and provide MMT as much advance notice as is reasonably possible
          of any such preclusion in order to permit MMT to prepare to undertake
          the applicable contract, including the contemporaneous preparation of
          its own bid.

          of this Agreement, without the prior written consent of MMT, it will

          beneficial ownership of any Voting Securities of MMT or any of its
          Subsidiaries, any securities convertible into or exchangeable for
          Voting Securities of MMT or any of its Subsidiaries, or any other
          right to acquire Voting Securities of MMT or any of its Subsidiaries,
          without the consent of MMT if the effect of such acquisition would be
          to increase the percentage of Voting Securities of MMT or such
          Subsidiary then beneficially owned directly or indirectly by LMC and
          its Affiliates to more than 4.9% of the Voting Securities of MMT or
          such Subsidiary then issued and outstanding.

     (b)  MMT agrees with LMC that, until three (3) years after the termination
          of this Agreement, without the prior written consent of LMC, it will
          not directly or indirectly (through an Affiliate or otherwise) acquire
          beneficial ownership of any Voting Securities of LMC or any of its
          Subsidiaries, any securities convertible into or exchangeable for
          Voting Securities of LMC or any of its Subsidiaries, or any other
          right to acquire Voting Securities of LMC or any of its Subsidiaries,
          without the consent of LMC if the effect of such acquisition would be
          to increase the percentage of Voting Securities of LMC or such
          Subsidiary then beneficially owned directly or indirectly by MMT and
          its Affiliates to more than 4.9% of the Voting Securities of LMC or
          such Subsidiary then issued and outstanding.

                                      -12-

<PAGE>   45

insolvency, fraudulent conveyance or other similar laws relating to or affecting
the enforcement of creditors' rights and remedies generally and by general
principles of equity, whether considered and applied by a court of law or
equity.

               3.   NO VIOLATION OF ARTICLES OF INCORPORATION, BY-LAWS, LAW, 
ETC. The execution, delivery and performance of this Agreement by each of LESAT
and Lockheed Martin have not constituted and will not constitute a violation or
breach of (i) the Charter, Certificate or Articles of Incorporation, as the case
may be, or By-Laws of either LESAT or Lockheed Martin, (ii) assuming compliance
with any required government notifications or permits, any agreement to which
LESAT or Lockheed Martin is subject except to the extent that such violation or
breach could not reasonably be expected to have a Material Adverse Effect on
LESAT or Lockheed Martin, as the case may be, or (iii) assuming compliance with
any required government notifications or permits, to the knowledge of LESAT or
Lockheed Martin, as the case may be, any applicable law, rule, regulation,
judgment, order or decree of any government instrumentality or court, domestic

respective properties (either real or personal).

               4.   BROKERS. Except for Donaldson, Lufkin & Jenrette (whose fees
will be paid by Lockheed Martin), no broker, finder, investment banker or
financial advisor has been retained on behalf of Lockheed Martin or LESAT in
connection with the transactions contemplated hereby which might be entitled to

hereto, (ii) the filing required pursuant to the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, and (iii) any filings that may be required by the
securities laws of the United States or state securities laws. With respect to
the required governmental filings, actions or consents, to the knowledge of
Lockheed Martin and LESAT, there are no facts relating to either of their
identity or circumstances, or those of M4 or Molten Metal, that could prevent or
materially delay the making of such filings or obtaining of such consents or
actions.

               6.   INVESTMENT PURPOSES. LESAT and Lockheed Martin understand 
that the Partnership Interest is being issued to LESAT and the Molten Metal 
Stock is being issued to LESAT in transactions not involving a public offering 
for purposes of the Securities Act of 1933, as amended (the "SECURITIES ACT"). 
Each of LESAT and Lockheed Martin is an "accredited investor," as that term is
defined in Rule 501 of Regulation D promulgated pursuant to the Securities Act.
LESAT is obtaining the Partnership Interest primarily for its own account and
not for distribution or resale to


                                      -13-

others. LESAT will not sell or otherwise transfer the Partnership Interest or
the Molten Metal Stock unless such security is registered under the Securities
Act or unless an exemption from such registration is available. Notwithstanding
the foregoing, the parties acknowledge and agree that LESAT is permitted to
transfer the Partnership Interest and the Molten Metal Stock to Martin Marietta
Environmental Holdings, Inc., Lockheed Martin or any direct or indirect wholly
owned subsidiary of Lockheed Martin, and that any such transfer shall not be
deemed to breach the provisions of this Subsection 6(f).

Schedule 6(g) attached hereto, as of the close of business on the date
immediately preceding the date hereof, LESAT had good title to all material
tangible items of the Acquired Assets regularly used in and necessary for the
conduct of the RETECH Business. The Acquired Assets as of the date of the
Closing will constitute all of the assets necessary to permit the continuation
of the RETECH Business in substantially the same manner as that business has
previously been conducted.

               8.   LITIGATION. Schedule 6(h) attached hereto sets forth all
actions, suits, hearings or other legal proceedings pending as of the date
immediately preceding the date of this Agreement before any court to which LESAT

could reasonably be expected to have a Material Adverse Effect on the RETECH
Business.

               9.   CONTRIBUTION OF LESAT ACQUIRED ASSETS. At the Closing, LESAT
shall contribute and transfer to M4 all of its right, title and interest in and
to the LESAT Acquired Assets, free and clear of all liens, encumbrances and
other rights of third parties, such that M4 will have free, clear and absolute
title to and ownership of the LESAT Acquired Assets, except for liens,
encumbrances and other rights of third parties described on Schedule 6(i) and
other non-material liens, encumbrances and other rights of third parties
incurred or created in connection with the operation of the RETECH Business in
accordance with the terms hereof from the date of this Agreement prior to the
Closing, all of which will be assumed by M4.

               10.  TRANSFER OF MMT ACQUIRED ASSETS. At the Closing, LESAT shall

               11.  RESTRUCTURING. LESAT and Lockheed Martin shall use their 
good faith reasonable efforts to cause the Restructuring to be consummated at or
prior to the date set for the Closing as described in the Partnership
Restructuring Agreement.

               12.  PROVISION OF WORKING CAPITAL FACILITY. Simultaneously with
the Closing, Lockheed Martin shall execute and deliver to M4 a revolving credit
agreement substantially in the form attached hereto as Exhibit 6(l).

this Agreement through the date of the Closing, LESAT shall give M4 and its
employees, accountants, attorneys and other authorized agents and
representatives reasonable access during reasonable hours to offices,
facilities, books and records of LESAT relating to the RETECH Business;
provided, however, (i) that M4 and its representatives shall schedule their
access and visits through a designated officer of LESAT and in such a way as to
avoid disrupting the normal business of LESAT; (ii) LESAT shall not be required
to take any action which could reasonably be expected to constitute a waiver of
any attorney-client privilege and work product doctrine; (iii) LESAT need not
supply M4 with any information which, in the reasonable judgment of LESAT, it is
under a legal obligation not to supply; and (iv) any information received by M4
and its representatives must be held in accordance with the Confidentiality
Agreement.

               14.  NON-CONTRAVENTION. Except as set forth in Schedule 6(n)
hereto, to the knowledge of LESAT and Lockheed Martin, neither the execution and
delivery of this Agreement by each of Lockheed Martin and LESAT nor the
performance by each of Lockheed Martin and LESAT of their obligations hereunder
will constitute a violation of or a default under, or result in the creation or
imposition of any lien or encumbrance upon any of the Acquired Assets pursuant
to, any agreement to which either Lockheed Martin or LESAT is a party or by
which either Lockheed Martin or LESAT or any of their properties (including,
without limitation, any of the Acquired Assets) is bound, except for any
violation, default or encumbrance that individually or in the aggregate could
not reasonably be expected to have a Material Adverse Effect on the RETECH
Business.

               15.  GOVERNMENTAL PERMITS. To the knowledge of LESAT and Lockheed
Martin, LESAT has and maintains, and Schedule 1(z) lists, all licenses, permits
and other authorizations from all governmental authorities required to be
maintained by it in connection with the conduct of the RETECH Business or in
connection with the ownership of the Acquired Assets, except for licenses,
permits or other authorizations where the failure of LESAT to have and maintain
any or all of such licenses, permits and authorizations individually or in the
aggregate could not reasonably be expected to have a Material Adverse Effect on
the RETECH Business.

               16.  FINANCIAL STATEMENTS. Lockheed Martin has delivered the
following financial statements to M4, and there are attached as Schedule 6(p)(i)
hereto: (i) a balance sheet for the RETECH Business as of December 31, 1995 and

condition of the RETECH Business as of its date, and each of such income and
cash flow statements fairly presents the results of operations and cash flows of
the RETECH Business for the period covered thereby.

               17.  ABSENCE OF CERTAIN CHANGES. Except as set forth on Schedule
6(q) or in the January Balance Sheet, since December 31, 1995, (i) LESAT has not
conducted the RETECH Business in a manner outside the ordinary course, and (ii)
there has been no change in the financial condition, results of operations,
assets, liabilities or business of the RETECH Business that individually or in
the aggregate could reasonably be expected to have a Material Adverse Effect on
the RETECH Business.

               18.  CONFORMITY TO LAW. Except as set forth on Schedule 6(r), to
the knowledge of LESAT, LESAT has complied in all material respects with, and is
in compliance in all material respects with, all laws, statutes, governmental
regulations and all judicial or administrative or tribunal orders, judgments,
writs, injunctions, decrees or similar commands applicable to the RETECH
Business or any of the Acquired Assets (including, without limitation, any
labor, environmental, occupational health, zoning or other law, regulation or
ordinance), except where the failure to comply individually or in the aggregate
could not reasonably be expected to have a Material Adverse Effect on the RETECH
Business. Except as set forth in Schedule 6(r) hereto, LESAT has not been
charged with or, to Lockheed Martin's or LESAT's knowledge, been under
investigation with respect to any violation of any provision of any national,
state or local law or administrative regulation in respect of the RETECH
Business or any of the Acquired Assets, except for any violation that

expected to have a Material Adverse Effect on the RETECH Business. Except as set
forth in Schedule 6(s) hereto, to the knowledge of LESAT and except for any
items that individually or in the aggregate could not reasonably be expected to

                                        Plan, the CAP Plan and the MICP Plan (as

                                        hereof), neither LESAT nor Lockheed

                                        once established, would come within the

                              RETECH Business. There is no labor strike,
                              dispute, slow-down or work stoppage actually
                              pending or to the knowledge of either Lockheed

                              knowledge of LESAT, no claim therefor has been
                              asserted. Except as set forth on Schedule 6(z),
                              none of the employees of LESAT is covered by any

                              any labor strike, dispute, slow-down or similar
                              work stoppage in the last three years relating to
                              the RETECH Business.

                    b.        Except as set forth on Schedule 6(z), since March

                              on Schedule 6(z), since March 14, 1995, no senior
                              employee of Lockheed Martin or any affiliate of

                              trade names and copyrights owned by and registered
                              in the name of LESAT or any of its affiliates
                              regularly used in and necessary for the conduct of
                              the RETECH Business and all applications therefor.
                              To the knowledge of LESAT, the IP Agreements
                              represent the only agreements relating to the
                              Intellectual Property regularly used in and
                              necessary for the conduct of the RETECH Business
                              which LESAT has licensed or authorized for use by
                              others or which has been licensed or authorized
                              for use in the RETECH Business to LESAT or any of
                              its affiliates.

                    b.        Except to the extent set forth in Schedule
                              6(aa)(ii) hereto, LESAT owns or has the sole and
                              exclusive right to use all Intellectual Property
                              regularly used in and necessary for the conduct of
                              the RETECH Business as presently conducted, and,
                              to the knowledge of LESAT, the consummation of the
                              transactions contemplated hereby will not alter or
                              impair any such right. Except as set forth in
                              Schedule 6(aa)(ii), to the knowledge of LESAT, no
                              royalties are paid or payable by LESAT on or with
                              respect to any of the Intellectual Property
                              pursuant to a written agreement, and upon the
                              consummation of the transactions contemplated
                              hereby, no additional 


                                      -23-

<PAGE>   56

                              royalties shall be payable with respect to such
                              Intellectual Property.

                    c.        To the knowledge of either Lockheed Martin or
                              LESAT, insofar as it relates to the RETECH
                              Business, no Transferred Employee is subject to
                              written confidentiality restrictions in favor of
                              any third Person the breach of which could subject
                              LESAT to any material liability or which could
                              materially adversely affect LESAT's access to the
                              Intellectual Property previously used by it
                              regularly and necessary for the conduct of the
                              RETECH Business. No claims have been asserted or
                              are pending against LESAT by any Person regarding
                              use of any such Intellectual Property by LESAT, or
                              challenging or questioning the validity or
                              effectiveness of any license or agreement relating
                              to the Intellectual Property to which LESAT is a
                              party, and, to the knowledge of either Lockheed
                              Martin or LESAT, there is no valid basis for such
                              a claim. To the knowledge of either Lockheed
                              Martin or LESAT, the use by LESAT of the
                              Intellectual Property listed in Schedule 1(p) does
                              not infringe on the rights of any person and LESAT
                              has not received any claim or written notice from
                              any Person to such effect. To the knowledge of
                              either Lockheed Martin or LESAT, no third party is
                              infringing, violating or otherwise using, in an
                              unauthorized manner, any Intellectual Property of
                              LESAT relating to the RETECH Business.

                    d.        Except as set forth on Schedule 6(aa)(ii), to the
                              knowledge of LESAT or Lockheed Martin, M4's
                              ability to use any of the Intellectual Property
                              set forth on any of the schedules referred to in
                              this Subsection 6(aa) will not be materially
                              adversely affected by the consummation of the
                              transactions contemplated hereby.

               28.  ACCOUNTS RECEIVABLE. To the knowledge of either Lockheed
Martin or LESAT, all Accounts Receivable are or will be valid obligations owing
to LESAT and will be paid in the ordinary course of business, net of the reserve
set forth in the January Balance Sheet (as appropriately updated to the date of
the Closing Date consistent with LESAT's past practices).



                                      -24-


<PAGE>   57

               29.  NO UNDISCLOSED LIABILITIEs. Except as set forth on any
Schedule hereto or as reflected or reserved against in the January Balance Sheet
and except for the Excluded Liabilities, to the knowledge of LESAT, LESAT has no
liabilities, indebtedness or obligations of any nature, whether accrued,
absolute, contingent or otherwise relating to the RETECH Business, which
pursuant to GAAP would be required to be reflected on a balance sheet of the
RETECH Business or a footnote thereto, except for liabilities reflected on the
January Balance Sheet, liabilities incurred since January 31, 1996 in the
ordinary course of business and liabilities which could not reasonably be
expected to have a Material Adverse Effect on the RETECH Business.

               30.  TAX MATTERS. Except as set forth in Schedule 6(ad), to the
knowledge of LESAT: 

                    a.        LIENS. There are no liens for Taxes (other than
                              current Taxes not yet due and payable) on any of
                              the Acquired Assets;

                    b.        WITHHOLDING TAXES. LESAT has withheld and paid all
                              Taxes in the approximate amounts required to have
                              been withheld and paid in connection with amounts
                              paid to any employee, creditor, independent
                              contractor or other third party for activities
                              relating to the RETECH Business; and

                    c.        PARACHUTE PAYMENTS. None of the Assumed
                              Liabilities represents an obligation to make any
                              payments, or an obligation that under certain
                              circumstances could obligate M4 to make any
                              payments, that will not be deductible under Code
                              Section 280G.

               31.  REAL PROPERTY. Attached as Schedule 6(ae) is a list of all
real property owned by LESAT or leased or subleased by LESAT regularly used in
and necessary for the conduct of the RETECH Business (the "REAL PROPERTY").
Neither LESAT nor Lockheed Martin has received any notice that any of the Real
Property is or will become subject to any condemnation or similar proceeding of
a substantial portion of a particular parcel of the Real Property or is in
violation in any material respect of any zoning or similar law.

               32.  UPDATING INFORMATION. LESAT or Lockheed Martin may elect at
any time to notify M4 and Molten Metal of any development causing any breach of
its representations, warranties or covenants in Subsections 6(a) - 6(ae) above
or may correct or update any disclosure schedule delivered hereunder. Any such
development, 


                                      -25-

<PAGE>   58

correction or update shall be treated as an undisclosed liability pursuant to
Subsection 15(d)(ii) hereof, subject, however, to the operation of Subsection
15(d)(ii)(B).

               33.  UPDATED SCHEDULES. LESAT shall, within forty-five (45) days
after the date of the Closing, provide to M4 updated Schedules 1(a), 1(f), 1(i),
1(k), 1(p), 1(q) and 1(z) hereto such that those schedules will set forth a
current description of the Acquired Assets as of the Closing.

               34.  INSPECTIONS. Each of LESAT and Lockheed Martin is an
informed, sophisticated business entity capable of understanding and evaluating
the merits and risks of its investment in M4 and Molten Metal. Each of LESAT and
Lockheed Martin has engaged such experts, counsel, consultants and advisors, has
undertaken such independent investigation, has made such independent evaluation
and has been provided with access to such documents and personnel of M4 and
Molten Metal, each as it has deemed necessary or appropriate in connection with
the transactions contemplated hereby based on its own independent investigation
and that neither M4 nor Molten Metal (and no one on their behalf) has made any
representation or warranty, express or implied, and neither LESAT nor Lockheed
Martin is relying on any representation or warranty, other than those expressly
set forth in this Agreement.

               35.  PARTNERSHIP INTEREST. At the Closing, Lockheed Martin shall
cause (i) the Partnership Interest to be issued to LESAT, and (ii) LESAT to be
admitted as a limited partner of M4.

               36.  CONVEYANCE OF ADDITIONAL ASSETS. If, subsequent to the
execution of this Agreement, LESAT determines that it retained an interest in an
asset regularly used in and necessary for the conduct of the RETECH Business,
LESAT shall promptly notify M4 of such asset and convey such asset to M4. If,
subsequent to the execution of this Agreement, M4 notifies LESAT that it
believes LESAT retained an interest in an asset regularly used in and necessary
for the conduct of the RETECH Business, LESAT shall, if it has retained an
interest in such an asset, promptly convey such asset to M4.

          N.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF M4. M4 represents,
warrants and covenants to LESAT, Lockheed Martin and Molten Metal as follows:

               1.   ORGANIZATION AND STANDING. (i) M4 is a limited partnership
duly formed, validly existing and in good standing under the laws of the State
of Delaware, (ii) M4 is qualified to do business as a foreign limited
partnership under the laws of each state or other jurisdiction in which the
failure to so qualify could reasonably be expected to have a Material Adverse
Effect on M4, and (iii) M4 has full power and authority to execute and deliver,
and consummate all transactions contemplated by, with respect to, or in
connection with, this Agreement.



                                      -26-

<PAGE>   59

               2.   DUE AUTHORIZATION AND ENFORCEABILITY. M4 is duly authorized
to execute and deliver this Agreement and all documents relating hereto to be
executed and delivered by it before or at the Closing and to take any and all
other action contemplated or required by this Agreement on behalf of it. Each of
the partners of M4 has consented in writing to M4 entering into this Agreement
specifically and consummating the Restructuring in general. This Agreement and
all other documents referred to herein to be executed and delivered by M4 to
LESAT, Lockheed Martin or Molten Metal at the Closing have or shall have been
duly and validly executed and delivered by M4 and, assuming due execution and
delivery by the other parties hereto or thereto, constitute or shall constitute
legal, valid, binding obligations of M4, enforceable against M4 in accordance
with their respective terms, except as enforceability may be limited by
applicable bankruptcy, insolvency, fraudulent conveyance or other similar laws
relating to or affecting the enforcement of creditors' rights and remedies
generally and by general principles of equity, whether considered and applied by
a court of law or equity.

               3.   NO VIOLATION OF PARTNERSHIP AGREEMENT, CERTIFICATE OF
PARTNERSHIP, LAW, ETC. The execution, delivery and performance of this Agreement
(including, without limitation, the issuance to LESAT of the Partnership
Interest) by M4 have not constituted and will not constitute a violation or
breach of (i) the Partnership Agreement (as defined in the Master Agreement) or
other constituting documents of M4, (ii) assuming compliance with any required
government notifications or permits, any agreement to which M4 is subject except
to the extent that such violation or breach could not reasonably be expected to
have a Material Adverse Effect on M4, or (iii) assuming compliance with any
required government notifications or permits, to the knowledge of M4, any
applicable law, rule, regulation, judgment, order or decree of any government
instrumentality or court, domestic or foreign, having jurisdiction over M4 or
its properties (either real or personal).

               4.   BROKERS. Except for Oppenheimer & Co. (whose fees were paid
by M4), no broker, finder, investment banker or financial advisor has been 
retained on behalf of M4 in connection with the transactions contemplated hereby
which might be entitled to payment from LESAT or Lockheed Martin.

               5.   GOVERNMENT APPROVALS. To the knowledge of M4, the execution,
delivery and performance of this Agreement and all other documents referred to
herein to be executed and delivered to LESAT, Lockheed Martin or Molten Metal at
the Closing do not require M4 to make any filing with or obtain any consent or
approval from any government instrumentality or court, federal, state, local or
foreign, except for (i) the filing required pursuant to the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 and (ii) any filings that may be required by
the securities laws of the United States or state securities laws. With respect
to the required governmental filings, actions or consents, to the knowledge of
M4, there are no facts relating to its identity or circumstances, or those of



                                      -27-

<PAGE>   60

Lockheed Martin, LESAT or Molten Metal, that could prevent or materially delay
the making of such filings or obtaining of such consents or actions.

               6.   LITIGATION. There is no action, suit or proceeding pending
against, or to the knowledge of M4, threatened against M4 which challenges or
seeks to enjoin or otherwise alter the transactions contemplated by this
Agreement.

               7.   INSPECTIONS. M4 is an informed, sophisticated business 
entity capable of understanding and evaluating the merits and risks of its 
business and the RETECH Business. M4 has engaged such experts, counsel, 
consultants and advisors, has undertaken such independent investigation, has 
made such independent evaluation and has been provided with access to such 
documents and personnel of LESAT, each as it has deemed necessary or appropriate
in connection with the transactions contemplated by this Agreement. M4 
acknowledges that it is entering into this Agreement and the transactions 
contemplated hereby based on its own independent investigation and that neither
Lockheed Martin nor LESAT (and no one on their behalf) has made any 
representation or warranty, express or implied, and M4 is not relying on any 
representation or warranty, other than those expressly set forth in this 
Agreement. IT IS THEREFORE EXPRESSLY UNDERSTOOD AND AGREED THAT M4 ACCEPTS THE 
CONDITION OF THE ACQUIRED ASSETS WITHOUT ANY REPRESENTATION, WARRANTY OR 
GUARANTEES, EXPRESS OR IMPLIED, AS TO MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE OR OTHERWISE AS TO THE CONDITION, SIZE, EXTENT, QUANTITY, TYPE OR VALUE
OF SUCH PROPERTY, EXCEPT ONLY AS MAY BE OTHERWISE EXPRESSLY PROVIDED IN THIS 
AGREEMENT, AND LESAT AND LOCKHEED MARTIN HEREBY EXPRESSLY DISCLAIM ANY AND ALL 
SUCH OTHER REPRESENTATIONS, WARRANTIES AND GUARANTEES.

               8.   CAPITAL STRUCTURE OF M4. M4 is authorized to issue the
following amounts and types of limited partnership equity interests: (i) one
percent general partner interest in M4, and (ii) ninety-nine percent limited
partner interests in M4. At the close of business on the business day next
preceding the date hereof, a one percent general partner interest in M4 and two
(2) forty-nine and one-half percent limited partner interests in M4 were issued
and outstanding, and all the issued and outstanding limited partnership equity
interests in M4 were and are duly authorized and validly issued. Other than with
respect to the Partnership Interest, there are no outstanding obligations,
options or rights of any kind entitling any persons to acquire a limited
partnership equity interest in M4 and there are no outstanding securities or
other instruments of any kind that are convertible into limited partnership
equity interests in M4.

               9.   STATUS OF PARTNERSHIP INTEREST. The Partnership Interest has
been duly authorized and, when issued as contemplated by this Agreement, will be
validly issued, fully paid and nonassessable, subject to Section 17-607 of the
Delaware Revised Uniform Limited Partnership Act. The Partnership Interest is
free and clear of all claims, 


                                      -28-

<PAGE>   61

liens, encumbrances and assessments whatsoever and is not subject to any other
rights of third parties, including, but not limited to, pre-emptive rights.

               10.  PARTNERSHIP INTEREST. At the Closing, M4 shall cause (i) the
Partnership Interest to be issued to LESAT, and (ii) LESAT to be admitted as a
limited partner of M4.

               11.  RESTRUCTURING. M4 shall use its good faith reasonable

               13.  RETECH SECURITY AGREEMENT. M4 acknowledges that LESAT is
obligated, pursuant to the RETECH Purchase Agreement, to ensure that the
acquiror of all or a substantial part of the RETECH Business grant a security
interest in certain patents and patent applications to Retech. Therefore, at or
prior to the Closing, M4 shall execute the RETECH Security Agreement and deliver
it to LESAT.

               14.  DUE DILIGENCE REPRESENTATIVES. The representatives of M4 set
forth in the definition of Due Diligence Representatives (as defined in
Subsection 15(l)) are the only employees, agents or other representatives of M4
that were involved in any material manner in the due diligence investigation
performed by M4 and the Due Diligence Representatives relating to this
Agreement, the Partnership Restructuring Agreement and the transactions
contemplated hereby or thereby.

          O.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF MOLTEN METAL AND THE

required government notifications or permits, to the knowledge of Molten Metal
and the MMT Subsidiary, any applicable law, rule, regulation, judgment, order or

hereto with any information which, in the reasonable judgment of the furnishing
party, it is under a legal obligation not to supply, and (c) any information
received by a party hereto from another party hereto shall be held in accordance
with the Confidentiality Agreement.

               3.   NONASSIGNABLE CONTRACTS.

                    (i) To the extent that any Contract is not capable of being
transferred by LESAT to M4 pursuant to this Agreement without the consent,
approval or waiver of a third Person, and such consent is not obtained prior to
the Closing, or if such transfer or attempted transfer would constitute a breach
thereof or a violation of any law, rule or regulation, nothing in this Agreement
will constitute a transfer or an attempted transfer thereof. Notwithstanding
anything contained in this Agreement to the contrary, LESAT is not obligated to
transfer to M4 any of its rights and obligations in and 


                                      -33-

                    (ii) In the event that such consents, approvals and waivers

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 consent is obtained LESAT will use
its best reasonable efforts, to the extent permitted by applicable law, the
terms of the Contract and the directions of the customer, to (a) cooperate in
any reasonable arrangement designed to provide to M4 the benefits and burdens of
any Contract referred to in subparagraph (i) above without incurring any
obligation to any other Person other than to provide such benefits to M4,
including without limitation the appointment of M4 as LESAT's agent for purposes
of such Contract, and (b) enforce, at M4's request for M4's account and at M4's
cost, any rights of LESAT arising from any such Contract (including without
limitation the right to elect to terminate such Contract in accordance with the
terms thereof upon the advice of M4).

                    (iii) No consent, approval or waiver of a third Person with
respect to the transfer of, or any novation with respect to, any Contract shall
cause an Excluded Liability to be deemed for purposes of this Agreement to have
become an Assumed Liability or vice-versa.

          U.   TERMINATION.

               1.   This Agreement shall be terminated, and the transactions
contemplated hereby abandoned, if the Closing shall not have occurred on or
before May 15, 1996 unless otherwise agreed by the parties hereto in writing. In
addition, this Agreement may be terminated at any time prior to the Closing:

                    a.   by the mutual consent in writing of the parties hereto;

                    b.   by LESAT or Lockheed Martin if there has been a 
material breach on the part of M4 or Molten Metal of any representation, 
warranty, covenant or other agreement of such party contained herein which 
cannot be or has not been cured within ten (10) days after written notice by 
LESAT and Lockheed Martin to M4 or Molten Metal, as the case may be, of such 
breach (provided that LESAT and Lockheed Martin are not then in material breach
of any representation, warranty, covenant or other agreement of those parties 
contained in this Agreement);

                    c.   by M4 if there has been a material breach on the part 
of Molten Metal, LESAT or Lockheed Martin of any representation, warranty, 
covenant or other agreement of such party contained herein which cannot be or 
has not been cured within ten (10) days after written notice by M4 to Molten 
Metal, LESAT or Lockheed Martin, as the case may be, of such breach (provided 
that M4 is not then in material breach of any representation, warranty, covenant
or other agreement of it contained in this Agreement); and

                    d.   by Molten Metal if there has been a material breach on
the part of M4, LESAT or Lockheed Martin of any representation, warranty,
covenant or other agreement of such party contained herein which cannot be or
has not been cured within ten (10) days after written notice by Molten Metal to
M4, LESAT or Lockheed Martin, as the case may be, of such breach (provided that
Molten Metal is not then in

material breach of any representation, warranty, covenant or other agreement of
it contained in this Agreement).

               2.   If this Agreement is terminated as provided above, all 
rights and obligations of the parties hereunder shall terminate without any 
liability of any party to any other party (except for any liability of any party
then in breach), provided, however, that confidentiality provisions of 
Subsection 18(k) and payment of expenses provisions of Section 16 shall survive
termination hereof.

          V.   SURVIVAL; INDEMNIFICATION.

               1.   SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties contained herein shall survive the Closing and
remain in full force and effect until the third (3rd) anniversary of the
Closing.

               2.   SURVIVAL OF COVENANT PROVISIONS. Each covenant provision
contained herein shall survive the Closing and remain in full force and effect
in accordance with its terms until the obligations arising thereunder have been
fully performed and discharged.

               3.   M4'S OBLIGATION. M4 agrees to, and does hereby, indemnify 
and hold harmless Molten Metal, LESAT and Lockheed Martin and, to the extent
actually indemnified by Molten Metal, LESAT or Lockheed Martin, each of their
respective officers, directors, partners, employees, agents, successors and
assigns (as a group, but separately for each business entity, the
"REPRESENTATIVES") from and against any and all Adverse Consequences that Molten
Metal, LESAT, Lockheed Martin or Representatives of any of them may suffer
resulting from, arising out of or in any way relating to (i) any material
misrepresentation in or material breach or non-fulfillment of any representation
or warranty of M4 or material non-fulfillment of any covenant, obligation or
agreement of M4 contained herein or in any Confidential treatment has been
requested for this portion of Exhibit 10.2.xhibit hereto or certificate or
document delivered hereunder or (ii) M4's failure to perform or in due course
pay, satisfy and discharge any Assumed Liability.

Representatives from and against any and all Adverse Consequences that M4,
LESAT, Lockheed Martin or their respective Representatives may suffer resulting
from, arising out of or in any way relating to any material misrepresentation in
or material breach or non-fulfillment of any representation or warranty of
Molten Metal or material non-fulfillment of any covenant, obligation or
agreement of Molten Metal contained herein or in any exhibit hereto or
certificate or document delivered hereunder.

               6.   LIMITATIONS.

                    a.   No party shall be entitled to make any claim for
indemnification under this Section 15 with respect to the breach of any
particular representation, warranty or covenant after the date upon which such
representation, warranty or covenant ceases to survive; provided, however, that
if prior to the date upon which such representation, warranty or covenant ceases
to survive, the party from whom indemnification is sought (the "INDEMNITOR")
shall have received written notification of a claim for indemnity with respect
thereto, specifying in reasonable detail the basis for the claim and indemnity
with respect thereto, and such claim shall not have been finally resolved or
disposed of at such date, the obligation of the Indemnitor under this Section 15
with respect to such claim shall continue until that claim is finally resolved
or disposed of; provided, however, that this provision shall not toll the
running of applicable statutes of limitation.

                                       *








               7.   NOTICE. No right to indemnification hereunder shall be
available to any party seeking indemnification (the "INDEMNITEE") unless the
Indemnitee shall have provided, promptly after acquiring knowledge of the
existence of a claim (or facts that might reasonably be expected to give rise to
a claim in the future), the Indemnitor a written notice describing in reasonable
detail the facts giving rise (or which might reasonably be expected to give rise
in the future) to the claim for indemnification hereunder and enclosing a copy
of any papers served upon the Indemnitee. In the case of the commencement of any
action or proceeding, "promptly" shall mean as soon as practicable, but in no
event later than ten (10) days after service of notice of the suit, commencement
of the action or proceeding or assertion of the claim. In the case of discovery
by the Indemnitee of any facts, loss or event giving rise (or which might
reasonably be expected to give rise in the future) to indemnity, "promptly"
shall mean as soon as practicable, but in no event later than thirty (30) days
after such discovery. The failure to give notice as required by this Subsection
15(g) shall not relieve the Indemnitor of any liability that it may have to the
Indemnitee except to the extent that the Indemnitor's ability to defend against
or mitigate Adverse Consequences associated with the event with respect to which
indemnification is sought is materially adversely affected by such failure. The
obligation to give notice as set forth in this Subsection 15(g) is in addition
to, and not in replacement of, the obligations and conditions set forth in the
other subsections of this Section 15.

               8.   PROCEDURE. In the event that indemnification is sought for
third party claims, the Indemnitor will have the right at any time to assume and
thereafter to conduct at its expense the defense of the third party claim with
counsel of recognized standing and competence of the Indemnitor's choice
(reasonably satisfactory to the Indemnitee); provided, however, that the
Indemnitor shall not consent to the entry of a judgment or enter into any
settlement with respect to the third party claim without the prior written
consent of the Indemnitee (which consent will not be unreasonably withheld)



- --------------------------
* Confidential treatment has been requested for this portion of Exhibit 10.2.



                                      -47-


<PAGE>   80

unless (i) the judgment or settlement involves only the payment of monetary
damages and does not impose an injunction or other equitable relief upon the
Indemnitee and (ii) the Indemnitor pays or causes to be paid all amounts arising
out of the judgment or settlement concurrently with the effectiveness thereof.
If the Indemnitor assumes the defense of the third party claim it shall allow
the Indemnitee a reasonable opportunity to monitor the defense thereof at the
Indemnitee's expense with counsel of recognized standing and competence of the
Indemnitee's choice (reasonably satisfactory to the Indemnitor). If the
Indemnitor does not assume the defense of the action, then the Indemnitee may
defend the action in any manner it may reasonably deem appropriate; provided,
however, that it shall allow the Indemnitor a reasonable opportunity to monitor
the defense thereof at the Indemnitor's expense with counsel of recognized
standing and competence of the Indemnitor's choice (reasonably satisfactory to
the Indemnitee). The party conducting the defense of an action shall at all
times reasonably and diligently pursue the resolution thereof and shall at all
times act in good faith and with reasonable prudence to minimize the Adverse
Consequences as though these were for its own account.

               9.   SHARED DEFENSE. The Indemnitee may elect to share in the
defense of a third party claim which has been assumed by Indemnitor. In that
event, the Indemnitee shall so notify the Indemnitor in writing. Thereafter,
each shall participate at its expense on an equal basis in the defense,
management and control of such claim. In this event, the Indemnitee and the
Indemnitor shall each be responsible for one-half (1/2) the Adverse
Consequences; subject, in the case of LESAT and Lockheed Martin, to the
aggregate cap on liability set forth in Subsection 15(f)(v) above.

               10.  COOPERATION. A party seeking indemnification for a third
party claim shall make available to the Indemnitor and its counsel all books,
records and documents relating to the claim and shall offer and cause its
Representatives to offer reasonable assistance in the defense of the claim.

               11.  REMEDIES. The indemnification provisions set forth in this
Section 15 shall constitute the exclusive remedy for LESAT, Lockheed Martin, M4,
Molten Metal and their Representatives for any alleged breach or default by any
party to this Agreement under this Agreement or in connection with or relating
to the transactions contemplated by this Agreement, other than claims based upon
fraud.

               12.  DEFINITIONS. As used in this Section 15, the following terms
shall have the following meanings.

                    a.   "DUE DILIGENCE DOCUMENT" shall mean any written 
document furnished to or, pursuant to a specific oral or written request, made 
available to any Due Diligence Representative at any time from and after July 1,
1995 to and including the date hereof in connection with the due diligence 
investigation performed by M4, Molten Metal, the MMT Subsidiary and the Due 
Diligence Representatives relating to this 


                                      -48-

<PAGE>   81

Agreement, the Partnership Restructuring Agreement and the transactions
contemplated hereby or thereby.

                    b.   "DUE DILIGENCE REPRESENTATIVES" shall mean Dr. Robert
Merriman, Thomas Valunas, Harry Nesteruk, Phillip M. Kannan, Robert Craig, Pat
Patton, Hal Haselton as representatives of M4, and William Haney III, Ethan
Jacks, Dr. Victor Gatto, Dr. Christopher Nagel, Benjamin Downs, Joseph
Grabmeier, Brigitte Smith, Barbara McWeeney and Elliot Mark as representatives 
of Molten Metal.

          W.   PAYMENT OF EXPENSES. Except as otherwise provided herein,
regardless of whether the transactions provided for herein are consummated, each
of the parties hereto shall pay all costs and expenses (including, without
limitation, all fees and expenses of their respective counsel) incurred by them
with respect to this Agreement and the transactions set forth herein and
contemplated hereby. M4 shall be responsible for any sales or transfer taxes
incurred (i) in connection with the transfer of the LESAT Acquired Assets by
LESAT to M4 and (ii) in connection with the transfer of the MMT Acquired Assets
by the MMT Subsidiary to M4, only to the extent not payable by Molten Metal
pursuant to clause (iii) below. MMT and the MMT Subsidiary shall be responsible
for any sales or transfer taxes incurred (i) in connection with the transfer by
LESAT to Molten Metal of the MMT Acquired Assets, (ii) in connection with the
transfer by Molten Metal to the MMT Subsidiary of the MMT Acquired Assets, and
(iii) in connection with the transfer of the MMT Acquired Assets by the MMT
Subsidiary to M4 but, with respect to this clause (iii), only to the extent that
such taxes are greater than would have been incurred if the MMT Acquired Assets
had been transferred directly from LESAT to M4. All other sales and transfer
taxes, and all recording, filing and other fees (including any penalties or
interest but not penalties or interest incurred with respect to sales and
transfer taxes covered by the preceding sentence), incurred in connection with
this Agreement and the transactions contemplated hereby will be borne by M4.

          X.   EMPLOYMENT AND EMPLOYEE BENEFIT MATTERS.

               1.   EMPLOYEE BENEFITS DEFINITIONS. The following terms shall 
have the following meanings:

                    a.   "CODE" means the Internal Revenue Code of 1986, as
amended.

                    b.   "ERISA" means the Employee Retirement Income Security 
Act of 1974, as amended.

                    c.   "TRANSFERRED EMPLOYEES" means the persons currently
employed by LESAT and listed on Schedule 17(a)(iii) hereto.



                                      -49-


<PAGE>   82

               2.   EMPLOYEES AND OFFERS OF EMPLOYMENT.

                    a.   M4 shall offer, or shall cause M4 Environmental
Management Inc., a Delaware corporation and general partner of M4 (the "GENERAL
PARTNER"), to offer, employment to commence on the date of the Closing to all
Transferred Employees and, except as provided in Subsection 17(e)(ii) and
Subsection 17(f) below, shall be a successor employer for all employment matters
with respect to Transferred Employees as of the date of the Closing. Each
Transferred Employee shall be offered a position similar to his or her position
immediately prior to the Closing Date, at the same job and salary or wage
levels, with bonus, incentive and retirement plans and other employee benefit
plans and arrangements which (at the minimum) shall be substantially comparable,
in the aggregate, to those provided to the Transferred Employees of the RETECH
Business immediately prior to the Closing Date. Each member of the senior
management of the RETECH Business (as reasonably determined by the President of
the General Partner and the Deputy General Manager of the RETECH Business, James
Crouch) shall be eligible to participate in the bonus and other incentive
programs of M4 or the General Partner, as the case may be, on a substantially
similar basis as current employees of M4 or the General Partner, as the case may
be, at similar levels with similar responsibilities. Such offers of employment
shall be for employment at will and shall be at the same respective locations as
those at which such Transferred Employees are employed immediately prior to the
date of the Closing.

                    b.   LESAT shall provide any notices to Transferred 
Employees which may be required under the Worker Adjustment Retraining and 
Notification Act, 29 U.S.C. [Section] 2101 ET SEQ., ("WARN") with respect to 
events which occur on or prior to the date of the Closing and M4 shall provide 
any notices to Transferred Employees which may be required under WARN with 
respect to events which occur after the date of the Closing or which become 
events requiring notice after the date of the Closing.

                    c.   LESAT will not take, and will cause each of its
affiliates not to take, any action which would impede, hinder, interfere or
otherwise compete with M4's or the General Partner's, as the case may be, effort
to hire any Transferred Employees.

               3.   WELFARE BENEFITS. Commencing as of the Closing Date, to the
extent that M4 or the General Partner, as the case may be, does not elect to
adopt life insurance, accidental death and dismemberment, long term disability,
and severance plans, and medical, vision and dental coverage plans with the same
benefit coverages as the plans offered to the Transferred Employees prior to the
Closing Date, M4 or the General Partner, as the case may be, shall provide the
Transferred Employees and dependents and beneficiaries thereof (the "ELIGIBLE
INDIVIDUALS") life insurance, accidental death and dismemberment, long term
disability, and severance coverage, and medical, vision and dental benefit 
coverage (at the minimum) substantially comparable, in the aggregate, to the 


                                      -50-

<PAGE>   83

coverage provided to the Transferred Employees under the plans listed as
Employee Benefit Plans on Schedule 6(x). Any welfare plans offered to the
Transferred Employees shall not include any exclusion for a pre-existing
condition (other than conditions excluded as of the Closing Date as pre-existing
conditions under existing medical, vision and dental coverage of Transferred
Employees if identical medical, dental or vision plans are adopted) and shall
take into account for purposes of any annual co-payment, deductible and
limitation on benefits, the payments made under the comparable Employee Benefit
Plan in respect of the Eligible Individuals for otherwise eligible medical,
vision and dental services in the current calendar year. Nothing in this
paragraph shall be construed to require M4 or the General Partner, as the case
may be, to extend any such coverage subsequent to a Transferred Employee's
termination of employment (except for continuation coverage required under Title
I, Part 6, of ERISA), on account of retirement or otherwise.

               4.   401(k) PLANS. On or prior to the Closing Date, M4 or the
General Partner shall designate a tax-qualified 401(k) plan (the "M4 401(k)
Plan") in which the Transferred Employees shall be eligible to participate
immediately upon the Closing. The M4 401(k) Plan shall credit, to the extent
applicable, for plan eligibility and vesting purposes service with LESAT prior
to the Closing Date. All contributions to the Lockheed Salaried Employee Savings
Plan Plus (the "LESAT 401(k)") and the Lockheed Capital Accumulation Plan (the
"CAP Plan") with respect to Transferred Employees shall be discontinued from and
after the Closing Date, but from and after that date each Transferred Employee
shall be fully vested in his or her account balance under the LESAT 401(k) Plan
and CAP Plan and shall be entitled to distribution of his or her account balance
to the extent authorized by, and subject to the limitations of, Section
401(k)(10) of the Code. M4 and the General Partner on the one hand and LESAT on
the other hand shall reasonably cooperate to facilitate the direct rollover of
distributions due the Transferred Employees from the LESAT 401(k) and CAP Plan
to the M4 401(k) Plan where elected by Transferred Employees.

               5.   LIABILITY.

                    a.        Except as otherwise provided in Subsection
                              17(e)(ii) or Subsection 17(f) below or in
                              Subsection 15(d), effective upon the Closing, M4
                              shall have exclusive liability for all claims
                              relating to the terms and conditions of employment
                              of the Transferred Employees, regardless of
                              whether such claim arises or is incurred before or
                              after the Closing or whether such claim is brought
                              by or with respect to a Transferred Employee or a
                              beneficiary of a Transferred Employee, including
                              but not limited to the following: all claims for
                              worker's compensation, vacation, holiday,
                              severance or layoff benefits, medical, life or
                              disability benefits, sickness and other 


                                      -51-


<PAGE>   84

                              leave; compensation (including incentive and bonus
                              programs); claims for discrimination, wrongful
                              termination, breach of contract, and similar
                              employment related matters; and claims for any
                              nonqualified or other fringe benefits.

                    b.        All of the liabilities referred to in Subsection
                              17(e)(i) above shall be considered Assumed
                              Liabilities for purposes of this Agreement, except
                              that any liabilities or obligations of any nature
                              of Retech that were not assumed by LESAT pursuant
                              to the RETECH Purchase Agreement shall not
                              constitute Assumed Liabilities for purposes of
                              this Agreement but as provided in the definition
                              thereof shall constitute an Excluded Liability for
                              purposes of this Agreement.

               6.   LIABILITY UNDER CERTAIN EMPLOYEE BENEFIT PLANS. LESAT and
Lockheed Martin shall have and retain exclusive liability and responsibility for
providing any and all benefits due and payable to or in respect of participants
and other beneficiaries under the LESAT 401(k), the CAP Plan and the Lockheed
Martin Management Incentive Compensation Plan (the "MICP PLAN") in accordance
with the terms of such Employee Benefit Plans and applicable law.

               7.   VACATION AND HOLIDAYS. As of the Closing Date, M4 or the
General Partner, as the case may be, shall adopt at its expense vacation and
holiday plans for Transferred Employees to succeed LESAT's vacation and holiday
plans applicable to the RETECH Business. These plans shall be (at the minimum)
identical (in the case of vacation plans) or substantially comparable, in the
aggregate (in the case of holiday plans), to the vacation and holiday plans
provided to the Transferred Employees immediately prior to the Closing Date and
shall be in place of what would have been provided to the Transferred Employees
under the current vacation and holiday plans had they remained employees of
LESAT, and LESAT shall have no liability or obligation to pay or provide any
vacation or holiday payments claimed on or after the Closing Date whether or not
due to vacation or holiday days earned before or after the Closing Date. Such
plans shall give credit to the Transferred Employees for their service with
LESAT as well as M4 or the General Partner, as the case may be.

               8.   ACCESS TO INFORMATION. Commencing with the date hereof and

LESAT in exchange for the applicable assets. LESAT has transferred the
applicable shares of Common Stock to LMC. Except as otherwise defined herein,
the capitalized terms used in this Agreement shall have the meanings ascribed to
them in the Asset Agreement.

     supplements to the Registration Statement and the prospectus used in
     connection therewith as may be necessary to keep such Registration
     Statement effective until the second anniversary of the Closing, or such
     time as all of the Registrable Securities covered by such registration

          (ii) furnish to LMC such number of copies of the Registration
     Statement, each amendment and supplement thereto, the prospectus included
     in the Registration Statement (including each preliminary prospectus) and
     such other documents as LMC may reasonably request in order to facilitate
     the disposition of the Registrable Securities owned by each such seller;

          (iii) use reasonable efforts to register or qualify the Registrable
     Securities under such other securities or blue sky laws of such states of
     the United States as LMC reasonably requests and do any and all other acts
     and things which may be reasonably necessary or advisable to enable LMC to
     consummate the disposition in such jurisdictions of the Registrable

          (iv) notify LMC, at any time when a prospectus relating thereto is

     necessary to make the statements therein not misleading, and, at the
     request LMC, the Company will promptly prepare (and, when completed, give
     notice to each seller of Registrable Securities) a supplement or amendment
     to such prospectus so that, as thereafter delivered to the purchasers of
     such Registrable Securities, such prospectus will not contain an untrue
     statement of a material fact or omit to state any fact necessary to make
     the statements therein not misleading; PROVIDED that upon such notification
     by the Company, LMC will not offer or sell Registrable Securities until the
     Company has notified LMC that it has prepared a supplement or amendment to
     such prospectus and delivered copies of such supplement or amendment to
     such seller;

          (v) cause all the Registrable Securities to be listed on each

     effectiveness of the Registration Statement, or of any order suspending or
     preventing the use of any related prospectus or suspending the
     qualification of any Registrable Securities included in the Registration
     Statement for sale in any jurisdiction, the Company will use reasonable
     efforts promptly to obtain the withdrawal of such order.

     (b) In the event that, despite the Company's compliance with paragraph (a)
above, the Registration Statement has not been declared effective by the
Commission within either (i) thirty (30) days after its filing date, if the
Registration Statement is not reviewed by the Commission, or (ii) ninety (90)
days after its filing date, if the Registration Statement is reviewed by the
Commission, LMC may, within ten (10) days after such date, request the Company
to repurchase the Registrable Securities. If so requested by LMC, MMT shall
within five days repurchase such Registrable Securities for a purchase price of
$23.72 per share (as appropriately adjusted from time to time to reflect any
stock splits, stock dividends or similar events), payable in cash.

     4.   Registration Expenses.
          ---------------------


     All expenses incident to the Company's performance of or compliance with
this Agreement, including without limitation all registration and filing fees,
fees and expenses of compliance with securities or blue sky laws, printing
expenses, messenger and delivery expenses, and fees and disbursements of counsel
for the Company and all independent certified public accountants and other
Persons retained by the Company, the Company's internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit or
quarterly review, the expense of any liability insurance for the Company and its
board of directors and the expenses and fees for listing the securities to be
registered on each securities exchange on which similar securities issued by the
Company are then listed (all such expenses being herein called "REGISTRATION
EXPENSES"), will be borne by the Company.

     5.   Indemnification.
          ---------------

     (a) The Company agrees to indemnify, to the extent permitted by law, LMC,
its officers and directors and each Person who controls LMC (within the meaning
of the Securities Act) against all losses, claims, damages and liabilities
caused by any untrue or alleged untrue statement of material fact contained in
the Registration Statement, prospectus or preliminary prospectus or any
amendment thereof or supplement thereto or any omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as the same are (i) caused by or
contained in any information furnished to the Company by LMC for use therein,
(ii) caused by LMC's failure to deliver a copy of the Registration Statement or
prospectus or any amendments or supplements thereto after the Company has
furnished LMC with a sufficient number of copies of the same, or (iii) caused by
LMC's sale of Registrable Securities in violation of the proviso to
[SECTION]3(iv) hereof.

     (b) In connection with the Registration Statement, LMC will furnish to the
Company in writing such information and affidavits as the Company reasonably
requests for use in connection with any such registration statement or
prospectus and, to the extent permitted by law, will indemnify the Company, its
directors and officers and each Person who controls the Company (within the
meaning of the Securities Act) against any losses, claims, damages and
liabilities resulting from any untrue or alleged untrue statement of material
fact contained in the Registration Statement, prospectus or preliminary
prospectus or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated 


<PAGE>   97

                                      -5-

therein or necessary to make the statements therein not misleading, but only to
the extent that such untrue or alleged untrue statement or omission or alleged
omission is attributable to the information furnished by LMC to the Company in
writing expressly for use in such registration statement or prospectus or
supplement thereto.

     (c) Any Person entitled to indemnification hereunder will (i) give prompt
written notice to the indemnifying party of any claim with respect to which it
seeks indemnification and (ii) unless in such indemnified party's reasonable
judgment a conflict of interest between such indemnified and indemnifying
parties may exist with respect to such claim, permit such indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. If such defense is assumed, the indemnifying party will not
be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent will not be unreasonably withheld). An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim will not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment of any indemnified party a
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim. Subject to the foregoing
terms and provisions of this [SECTION]5(c), each indemnifying party hereunder
will reimburse the person entitled to indemnification hereunder for all legal
and other expenses reasonably incurred in connection with investigating and
defending the action or claim for which such indemnified party seeks
indemnification, as such expenses are incurred.

     (d) The indemnification provided for under this Agreement will remain in
full force and effect regardless of any investigation made by or on behalf of
the indemnified party or any officer, director or controlling Person of such
indemnified party and will survive the transfer of securities.

     6. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS. No Person may participate
in any offering hereunder which is underwritten unless such Person (i) agrees to
sell such Person's securities on the basis provided in any underwriting
arrangements approved by the Person or Persons entitled hereunder to approve
such arrangements (as provided in Section 3(vi)) and (ii) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements;
PROVIDED, that no holder of Registrable Securities included in any underwritten
registration shall be required to make any representations or warranties to the
Company or the underwriters other than representations and warranties regarding
such holder and such holder's intended method of distribution.

                      Transferability of Partner Interests
                      ------------------------------------

     6.1. Restrictions on Transfer.
          ------------------------

     (a) No Limited Partner shall have the right to dispose of, sell, alienate,
assign, participate, subparticipate, encumber, or otherwise transfer all or any
part of its interest in the Partnership (other than assignments by operation of
law) unless prior to such transfer the transferee is approved in writing by the
General Partner (or by each General Partner, if at any time and from time to
time there is more than one), acting in its absolute discretion.

     (b) The transferee of the Partnership interest of a Limited Partner may
become a substituted Limited Partner only upon the terms and conditions set
forth in this Article 6. The General Partner shall have the power, in its sole
discretion, to admit or to refuse to admit as substituted Limited Partners
transferees who acquire the interest, or any part thereof, of a Limited Partner
hereunder; PROVIDED, that if at any time and from time to time there is more
than one General Partner, the unanimous consent of the General Partners shall be
required to admit such transferees as substituted Limited Partners. Except as
otherwise provided in this Article 6, the failure or refusal of the General
Partner to admit an assignee as a substituted Limited Partner shall not affect
the right of such assignee to receive the share of distributions of the
Partnership 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 Partner of the Partnership, including without limitation the
right to vote or consent with respect to any proposed action of the Partnership
as to which such vote or consent is required, unless and until the assignee is
admitted as a substituted Limited Partner. From and after the assignment of any
interest or portion thereof, the assignor shall not be entitled to exercise any
rights of a Partner of the Partnership 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 Partnership, regardless of whether its
assignee becomes a substituted Limited Partner. An assignee of a Limited
Partner's interest who does not become a substituted Limited Partner 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 6 to the same extent as any
Limited Partner desiring to make an assignment.

     (c) In addition to the foregoing requirements, the admission of an assignee
as a substituted Limited Partner 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 Partnership 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 



<PAGE>   115



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 Partnership in connection with the admission
to the Partnership of a substituted Limited Partner pursuant to this Article 6
shall be borne by the transferor Limited Partner (and if not timely paid, by the
substituted Limited Partner), including, without limitation, costs of any
necessary amendment hereof, filing fees, if any, and reasonable attorneys' fees.

     (e) Notwithstanding anything in this Agreement to the contrary, LESAT shall
be permitted to assign its entire limited partner interest in the Partnership to
LMC or a Subsidiary of LMC without any further act, vote or approval of any
Partner, and LMC or such Subsidiary shall be deemed admitted as a substituted
Limited Partner upon its execution and delivery of a counterpart of this
Agreement (if such assignee had not already been admitted as a Limited Partner).

     6.2. ADDITIONAL RESTRICTIONS. Anything contained in the foregoing
provisions of this Article 6 expressed or implied to the contrary
notwithstanding:

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

     (b) In no event shall all or any part of a Limited Partner's interest in
the Partnership be assigned or transferred to a minor or incompetent.

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

     (d) Any sale, transfer, assignment, exchange, or other disposition in
contravention of any of the provisions of this Article 6 shall be void and
ineffectual and shall not bind or be recognized by the Partnership.

     6.3. CONTINUATION OF PARTNERSHIP. The liquidation, dissolution, bankruptcy,
insolvency, death, or incompetency of any Limited Partner shall not terminate
the business of the Partnership or dissolve the Partnership, which shall
continue to be conducted upon the terms of this Agreement by the other Partners
and by the personal representatives and successors in interest of such Limited
Partner.

     6.4. TRANSFER OF INTEREST OF THE GENERAL PARTNER. The General Partner may
not sell, transfer, assign, pledge, encumber, mortgage or otherwise hypothecate
(hereinafter in this Section 6.4 collectively referred to as "assign" or
"assignment") the whole or any part of its interest as General Partner in the
Partnership without the unanimous written consent of the Limited Partners. An
assignee of all or part of the interest of the General Partner in the
Partnership shall be admitted to the Partnership as a general partner of the
Partnership only if the Limited Partners approve in writing the admission of
such assignee as an additional or successor general partner of the Partnership.
If such unanimous written consent is obtained, the admission shall be effective
upon the filing of an amendment to the Certificate of Limited Partnership of the
Partnership with the Secretary of State of the State of Delaware which indicates
that such Person has been admitted to the Partnership as a general partner of
the Partnership, and shall occur and for all purposes shall be deemed to have
occurred, immediately prior to the time the assignor ceases to be a general
partner of the Partnership. Such additional or successor General Partner is
hereby authorized to and shall continue the Partnership without dissolution.
Upon the filing of an amendment to the Certificate of Limited Partnership of the
Partnership with the Secretary of State of the State of Delaware which indicates
that the General Partner is no longer a general partner of the Partnership, the
General Partner shall at that time cease to be a general partner of the
Partnership.

                                    Article 7
                                    ---------

                                  Distributions
                                  -------------

     (a) DISTRIBUTIONS. If at any time and from time to time the General Partner
determines that the Partnership has cash that is not required for the operations
of the Partnership, the payment of liabilities or expenses of the Partnership,
or the setting aside of reserves to meet the anticipated cash needs of the
Partnership, the General Partner shall distribute all or any portion of that
excess cash to the Partners in proportion to their Percentage Interests, unless
the distribution is a liquidating distribution, which shall be made in the
manner set out in Section 9.2.

     (b) RESTRICTED DISTRIBUTIONS. The Partnership, and the General Partner on
behalf of the Partnership, shall not make a distribution to any Partner on
account of its interest in the Partnership if and to the extent such
distribution would violate [SECTION]17-607 of the Act or other applicable law.

                                    Article 8
                                    ---------

                        Allocations of Profits and Losses
                        ---------------------------------

     8.1. ALLOCATIONS OF PROFITS; GENERAL. Except as provided in Sections 8.4
through 8.8 below, and after application of Section 8.3 and Section 9.3, all net
profits and credits of the Partnership (for both accounting and tax purposes)
for each 



<PAGE>   117

                                      -16-

fiscal year shall be allocated to the Partners from time to time (but no less
often than once annually and before making any distribution to the Partners) in
proportion to their Percentage Interests.

     8.2. ALLOCATIONS OF LOSSES; GENERAL. Except as provided in Sections 8.4
through 8.8 and Section 9.3 below, and after application of Section 8.3, all net
losses of the Partnership for each fiscal year (for both accounting and tax
purposes), and all Nonrecourse Deductions, shall be allocated to the Partners
from time to time (but no less often than once annually and before making any
distribution to the Partners) in proportion to their Percentage Interests.

     8.3 SPECIAL ALLOCATIONS. Except as provided in Sections 8.4 through 8.8
below, notwithstanding the provisions of Section 8.1 and 8.2, and before making
any allocations thereunder, items of Partnership gross expense, loss, and
deduction for each fiscal year (for both accounting and tax purposes) of the
Partnership shall be specially allocated to the Partners until the Partners'
Capital Accounts are in proportion to the Partners' respective Percentage
Interests (or in proportion to the aggregate amounts then allocable to the
Partners under this Section 8.3, if the total amount to be allocated is less).

     8.4. LIMITATION. Notwithstanding anything otherwise provided in Sections
8.2 or 8.3, no Partner will be allocated any items of Partnership expense,
deduction or losses to the extent such allocation results in such Partner's
Capital Account having a deficit balance in excess of the sum of (i) such
Partner's obligation, if any, to restore deficits on the dissolution of the
Partnership and (ii) such Partner's deemed obligation to restore deficits
pursuant to Treasury Regulations [SECTIONS]1.704-2(g)(1) and 1.704-2(i)(5) (the
"UNPERMITTED DEFICIT"); any items of Partnership expense, deduction or losses
not allocable to a Partner under this sentence shall be allocated to the other
Partners. In the event any Partner's Capital Account is adjusted (by way of
distribution, allocation or otherwise) to create an Unpermitted Deficit, such
Partner shall, as soon as possible thereafter, be allocated items of Partnership
income to eliminate the Unpermitted Deficit. In addition to the foregoing, if at
the end of any fiscal year of the Partnership, there is a net decrease in
Partnership Minimum Gain, as compared to the end of the previous fiscal year,
prior to any other allocation of profits and losses for such year except that
provided in Section 8.5, each Partner shall be allocated (or if more than one
Partner has a share of such net decrease, all such Partners shall be allocated
ratably between them in accordance with their respective shares) items of
Partnership income for such year (and, if necessary, subsequent fiscal years)
equal to such Partner's share of the net decrease of Partnership Minimum Gain
determined in accordance with Treasury Regulation [SECTION]1.704-2(g).
Notwithstanding any provision in this Agreement to the contrary, no Partner
shall have any obligation to restore any deficit balance in such Partner's
Capital Account.




<PAGE>   118

                                      -17-

     8.5. PARTNER NONRECOURSE DEDUCTIONS. Any Partner Nonrecourse Deductions for
any fiscal year or other period shall be allocated to the Partner who (in its
capacity, directly or indirectly, as lender, guarantor, or otherwise) bears the
economic risk of loss with respect to the loan to which such Partner Nonrecourse
Deductions are attributable in accordance with Treasury Regulations
[SECTION]1.704-2(i) or any successor regulation. If at the end of any
Partnership fiscal year there is a net decrease in Partner Minimum Gain
attributable to such loan as compared to the end of the previous fiscal year
(and, if necessary, subsequent fiscal years), such net decrease shall be charged
back to that Partner in the manner and to the extent required by Treasury
Regulations [SECTION]1.704-2(i)(4) or any successor regulation, pursuant to
procedures analogous to those set out in the penultimate sentence of Section
8.4.

     8.6. CALCULATION OF PROFITS AND LOSSES. For all purposes hereof, the
Partnership's profits and losses shall be determined by taking into account all
of the Partnership'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.

     8.7. GENERAL PARTNER'S 1% SHARE. Notwithstanding the foregoing provisions
of this Article 8, in no event shall there be allocated to the General Partner
hereunder less than 1% of the aggregate of the profits, losses or credits (or
any item thereof) to be allocated to the Partners hereunder. If the amounts of
profits, losses or credits (or of any item thereof) allocable to the General
Partner shall not otherwise equal or exceed such 1% share without giving effect
to this provision, then all such amounts otherwise allocable to the Limited
Partners hereunder shall be reduced in order to assure the General Partner of
such one percent share, and the next subsequent allocations to the Partners
shall be adjusted as appropriate (and consistent with this Section 8.7) in order
to compensate for any adjustment under this Section 8.7.

     8.8. SECTION 704(C) AND CAPITAL ACCOUNT REVALUATION ALLOCATIONS. The
Partners agree that to the full extent possible with respect to the allocation
of depreciation, amortization or any other cost recovery deduction, loss and
gain for federal income tax purposes only, SECTION 704(c) of the Code shall
apply with respect to non-cash property contributed to the Partnership by any
Partner. Accordingly, (i) if the tax basis of any property contributed differs
from its agreed value for purposes of determining Capital Accounts (the "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 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 Partner; and
(ii), to the extent of the 704(c) Difference, any remaining tax depreciation,
amortization or other cost recovery 



<PAGE>   119

                                      -18-


deductions with respect to such property shall, for each fiscal year, be
specially allocated to the other Partners, 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 Partners 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 Partner, and the 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 Partners and the amount allocated to the
Partners for purposes of determining Capital Accounts. For purposes hereof, any
allocation of income, loss, gain or any item thereof to a Partner pursuant to
Section 704(c) of the Code shall affect only its tax basis in its Partnership
interest and shall not affect its Capital Account in the Partnership. In
addition to the foregoing, if Partnership assets are reflected in the Capital
Accounts of the Partners at a book value that differs from the adjusted tax
basis of the assets (E.G., because of a revaluation of the Partners' Capital
Accounts under Treasury Regulations [SECTION]1.704-1(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 Partners in a manner
consistent with the principles of Section 704(c) of the Code and this Section
8.8.

                           Dissolution and Winding Up
                           --------------------------

     9.1. General. (a) The Partnership shall be dissolved and its affairs shall
be wound up upon:

           (i) the expiration of the term of the Partnership as set forth in
               Section 2.4 of this Agreement;

          (ii) 

                                        *
                                        -



         (iii) an event of withdrawal of the General Partner (as defined in
               [SECTION]17-402 of the Act), unless the business of the
               Partnership is continued as provided in the Act (any additional
               or successor General Partner of the Partnership is hereby
               authorized to and shall continue the business of the Partnership
               without dissolution); or

          (iv) the unanimous written consent of the Limited Partners pursuant to
               Section 4.8(vii).

     (b) Upon dissolution of the Partnership, the business of the Partnership
shall continue for the sole purpose of winding up its affairs. The winding up
process shall be carried out by the General Partner unless the dissolution is
caused by an event of withdrawal (as defined in [SECTION]17-402 of the Act) by
the sole remaining General Partner, in which case a liquidating trustee may be
appointed for the Partnership by vote of a majority in Percentage Interest of
the Limited Partners (the General Partner or such liquidating trustee is
referred to herein as the "LIQUIDATOR"). In winding up the Partnership's
affairs, every effort shall then be made to dispose of the assets of the
Partnership in an orderly manner, having regard to the liquidity, divisibility
and marketability of the Partnership's assets. If the Liquidator determines that
it would be imprudent to dispose of any non-cash assets of the Partnership, such
assets may be distributed in kind to the Partners, 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 Partners of each kind of those assets that are to be
distributed in kind. The Liquidator shall not be entitled to be paid by the
Partnership any fee for services rendered in connection with the liquidation of
the Partnership, but shall be reimbursed by the Partnership for all third-party
costs and expenses incurred by it in connection therewith and shall be
indemnified by the Partnership with respect to any action brought against it in
connection therewith by applying, mutatis mutandis, the provisions of Article
13.

     9.2. APPLICATION AND DISTRIBUTION OF PARTNERSHIP ASSETS. The assets of the
Partnership in winding up shall be applied or distributed as follows: FIRST, to
creditors of the Partnership, whether by payment or the making of reasonable
provision for the payment thereof, and including any contingent, conditional and
unmatured liabilities of the Partnership, taking into account the relative
priorities thereof, and SECOND, to the Partners 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 Partnership shall be retained by the Partnership until such
winding up is completed or such reserve is otherwise deemed no longer necessary
by the Liquidator. Subject to the provisions of [SECTION] 17-804(a)(1) of the
Act, if the Partnership is dissolved by mutual agreement, the LMC Subsidiary
shall have returned to it, prior to any distribution to the Partners pursuant to
clause SECOND above, any cash Capital Contribution that the LMC Subsidiary has
made to the Partnership but which has not yet been expended by the Partnership
(with any expenses of the Partnership being deemed to have been made out of cash
Capital Contributions prior to any cash on hand that does not represent a
Capital Contribution). Any such preferential return to the LMC Subsidiary of its
Capital Contributions is referred to herein as a "RETURN OF CAPITAL".

     9.3. CAPITAL ACCOUNT ADJUSTMENTS. For purposes of determining a Partner's
Capital Account, if, on liquidation and dissolution, some or all of the assets



<PAGE>   121

                                      -20-

of the Partnership are distributed in kind, Partnership profits (or losses)
shall be increased by the profits (or losses) that would have been realized had
such assets been sold for their fair market value on the date of dissolution of
the Partnership, as determined by the Liquidator. Any such increase pursuant to
the preceding sentence, or any actual profit or loss realized if, on liquidation
or dissolution, some or all of the assets of the Partnership are sold, (i) shall
be allocated to the Partners in accordance with Article 8 hereof EXCEPT that the
special allocation procedure set forth in Section 8.3 shall be applied after
taking into account the effect of any Return on Capital on the Partners' Capital
Accounts, not only with respect to the items set forth therein, but also with
respect to any items of gross income and gain resulting from such hypothetical
or actual sale and (ii) shall increase (or decrease) the Partners' Capital
Account balances accordingly, it being the general intent that the adjustments
contemplated by this subsection shall have the effect, as nearly as possible, of
causing the Partners' Capital Account balances to be in proportion to their
Percentage Interests.

     9.4. Termination of Partnership.
          --------------------------

     The Partnership shall terminate when all assets of the Partnership, after
payment of or due provision for all debts, liabilities and obligations of the
Partnership, shall have been distributed to the Partners in the manner provided
for in this Article 9, and the Certificate of Limited Partnership of the
Partnership shall have been canceled in the manner required by the Act.

                                   ----------

                          Financing of the Partnership
                          ----------------------------

     10.1. OBLIGATION TO FUND OPERATING BUDGET. (a) The LMC Subsidiary agrees
that it shall fund the operations of the Partnership through August 1, 1999 on
the basis provided in this Section 10.1. The Executive Committee shall request
funding from the LMC Subsidiary from time to time (but no less often than
annually) to fund the operations of the Partnership, including any equity
required in order to obtain project financing for a CEP Plant. The LMC
Subsidiary shall provide the funds requested by the Executive Committee from
time to time, to the extent the Executive Committee considers such funding
reasonably necessary for the anticipated operations of the Partnership based on
the Business Plan. In no event, however, shall the LMC Subsidiary be obligated
pursuant to this Section 10.1 to provide more than $20,000,000 in any one fiscal
year or more than $75,000,000 in the aggregate from the date of the Original
Agreement through the term of this Agreement, in each case excluding any
Additional Capital Contribution made by the LMC Subsidiary, if any, in order to
finance its share of the purchase price to be paid by the Partnership pursuant
to the Asset Acquisition Agreement or similar agreement contemplated by Section
2.1 of the Restructuring Agreement. Any funding shall be 



<PAGE>   122

                                      -21-


made within ten (10) business days after the funding request of the Executive
Committee by wire transfer to an account designated by the Partnership at least
two (2) business days prior to the due date.

     (b) If the Partnership requires additional equity financing in excess of
the $20,000,000/$75,000,000 amounts referred to above, the Partners foresee that
such additional funding will be provided by the Partners in proportion to their
respective Percentage Interests, and if not funded by a particular Partner, such
additional equity financing will be dilutive and will reduce the non-funding
Partner's Percentage Interest on a basis to be determined by the General
Partner. The requirement for any such additional financing, including any equity
financing for capital expenses or acquisitions, will be discussed and resolved
on a case-by-case basis and must be agreed to by all the Partners.

     (c) All funding provided pursuant to paragraph (a) above shall be treated
as Additional Capital Contributions by the LMC Subsidiary. Any Capital
Contribution made by the LMC Subsidiary on the date of the Original Agreement,
including the funding of the Partnership's obligation under the MMT License
Agreement, and any additional capital contribution to the General Partner, in
its capacity as a stockholder of the General Partner, on or after the date of
the Original Agreement by the LMC Subsidiary not matched by the MMT Subsidiary,
shall reduce the foregoing obligation of the LMC Subsidiary to make Additional
Capital Contributions by an equal amount.

     10.2. OBLIGATION TO PROVIDE PROJECT GUARANTIES. (a) The Partners agree that
CEP Plants are to be financed by project and/or third-party financing to the
maximum extent reasonably possible. In the event that acceptable project and/or
third-party financing is not available for an identified CEP Plant on this basis
after reasonable efforts, and if the Executive Committee has approved that CEP
Plant, then subject to the conditions set forth in paragraph (b) below, the LMC
Subsidiary agrees that for such CEP Plant it will provide a guaranty (or if
requested by lenders obtain such a guaranty from LMC) of the third-party
financing obtained for such CEP Plant (each a "PROJECT GUARANTY"). Any such
Project Guaranty shall be an irrevocable unconditional guaranty of payment of
the applicable financing and shall be on commercial terms typically found in
project guarantees delivered by major corporations (including LMC) for project
financing provided by national institutional lenders.

     (b) The obligations of the LMC Subsidiary to provide a Project Guaranty
with respect to any particular CEP Plant is subject to the following



<PAGE>   123

                                      -22-

    conditions:

                                       -
























     (c) For each Project Guaranty provided by the LMC Subsidiary or LMC for any
CEP Plant, the LMC Subsidiary shall receive an annual fee (the "PROJECT GUARANTY
FEE") from the Partnership equal to 2% of the average amount of debt outstanding
during such year that was guaranteed by such Project Guaranty. The Project
Guaranty Fee payable with respect to any year shall be paid at the same time
that the Royalty Payments (as defined in the MMT License Agreement) for such
year are payable pursuant to the MMT License Agreement.

                                   ----------

              Transactions With the Partnership; Operational Issues
              -----------------------------------------------------

     11.1. GENERAL. Except as otherwise provided in this Agreement, any Limited
Partner and any Affiliate of any Limited Partner may lend money to, act as
surety, guarantor or endorser for, guarantee or assume one or more specific
obligations of, provide collateral for, and transact other business with the
Partnership and, subject to applicable law, shall have the same rights and
obligations with respect thereto as a Person who is not a partner in the
Partnership. Any transactions between a Limited Partner or an Affiliate of a
Limited Partner shall be on the terms approved by the General Partner from time
to time or, if such transaction is contemplated by this Agreement, the Master
Agreement, the Restructuring Agreement, the Loan Agreement or the MMT License
Agreement, on the terms provided for in such Related Agreement. The exercise of
any such right by a Limited Partner shall not cause a Limited Partner to be
deemed to be participating in the control of the business of the Partnership.

     11.2. STAFFING; COMPENSATION. The General Partner shall staff the
Partnership with management and other employees on the basis contemplated by the
Business Plan. The General Partner shall create appropriate compensation
packages for Partnership personnel, including an equity or equity-linked
incentive plan.

     11.3. SUPPLEMENTARY ASSISTANCE; MARKETING. (a) The Partnership may request
the assistance from time to time of MMT or LMC personnel to supplement the
Partnership's own business activities, including without limitation the
Partnership's sales and marketing efforts and regulatory, permitting and
government regulation activities. The MMT Subsidiary and the LMC Subsidiary
shall cause MMT or LMC, as applicable, to furnish the appropriate personnel from
time to time to support the Partnership's activities. MMT or LMC shall be
compensated for such activities as provided in Section 11.4, excluding, however,
services provided by MMT or LMC which are of general support of the business of
the Partnership (as compared with project-specific activities) and would
normally fall within the classification of selling, general and administrative
costs or expenses.

     (b) In connection with these sales and marketing efforts, the MMT
Subsidiary shall make available to the Partnership all existing contract
opportunities available to MMT for the Market. The General Partner shall cause
all marketing activities to be conducted in the name of the Partnership and in
such a manner as to emphasize the status of the Partnership as an entity
separate and apart from LMC and MMT. In addition, the General Partner will not
cause the Partnership to issue any material press releases until such press
releases have been reviewed by designees of the MMT Subsidiary and the LMC
Subsidiary as contemplated by Section 10 of the Master Agreement and Article 12
of the Restructuring Agreement.



<PAGE>   125

                                      -24-


     11.4. GOODS AND SERVICES. (a) The Partnership shall be required to
purchase, and the MMT Subsidiary and the LMC Subsidiary shall be required to
furnish (to the extent available), goods and services from the LMC Subsidiary or
LMC, and the MMT Subsidiary or MMT, as applicable, where such goods and services
are essential to the Partnership and, because of their nature, cannot be readily
obtained from third parties or developed or produced internally by the
Partnership. These goods and services include, in the case of the MMT Subsidiary
or MMT, the goods and research and development and other services to be provided
by MMT to the Partnership and its sublicensees on the basis set forth in Article
9 of the MMT License Agreement.

     (b) The Partnership shall reimburse MMT, LMC, the LMC Subsidiary or the MMT
Subsidiary, as applicable, for any goods and services provided to the
Partnership pursuant to this Article 11. Any such reimbursement to any Person
shall be (i) in the case of any goods and services provided in connection with a
contract that will not allow costs incurred under an arrangement of the type set
forth in clause (ii) below, an amount equal to the Permitted Costs incurred plus
a profit in an amount equal to * of the estimated costs for such goods and
services proposed by such Person and accepted by the Partnership, (ii) in the
case of any goods and services not required to be accounted for as provided in
clause (i) above, an amount equal to * of the Permitted Costs incurred, and
(iii) in the case of any goods sold by such Person pursuant to catalog or other
standardized prices, and notwithstanding the provisions of clauses (i) and (ii)
above, the standard price for such goods. The General Partner shall adopt and
implement procedures relating to billing, documentation and payment terms for

Restructuring Agreement) and any member of the Executive Committee
(collectively, the "INDEMNITEES") shall have no liability to the Partnership or
to any Partner for any loss suffered by the Partnership or such Partner that
arises out of any action or inaction of the General Partner (or any other
Indemnitee) if the General Partner or such other Indemnitee, in good faith,
determined that such course of conduct was in the best interests of the
Partnership and such course of conduct did not constitute gross negligence or
willful misconduct of the General Partner (or other Indemnitees). To the fullest
extent permitted by law, the General Partner (and such other Indemnitees) shall
be indemnified by the Partnership against any losses, judgments, liabilities,
expenses (including, without limitation, reasonable attorneys' fees and court

Indemnitee acting in connection with the Partnership's business or affairs shall
not be liable to the Partnership or to any Partner for its good faith reliance

Indemnitee otherwise existing at law or in equity, are agreed by the Partners to

compensated at a fair market rate for its services), (g) manage the
Partnership's liabilities separately from those of any Affiliate and pay its own
liabilities, including all administrative expenses and compensation to
employees, consultants or agents, and all operating expenses, from its own
separate assets, except that an Affiliate may pay the organizational expenses of
the Partnership, and (h) pay from the Partnership's assets all obligations and
indebtedness of any kind incurred by the Partnership. The Partnership shall
abide by all partnership formalities, including the maintenance of current
records of Partnership affairs, and the Partnership shall cause its financial
statements to be prepared in accordance with generally accepted accounting
principles in a manner that indicates the separate existence of the Partnership.
The Partnership shall (i) pay all its liabilities, (ii) not assume the
liabilities of any Affiliate and (iii) not guarantee the liabilities of any
Affiliate. The General Partner shall make decisions with respect to the business
and daily operations of the Partnership independent of and not dictated by any

                                 Indemnification
                                 ---------------

<PAGE>   129

                                      -28-

ownership, construction, start-up or operation of any CEP Plant or other
facility developed by the Partnership or any sublicensee of the Partnership (a
"THIRD PARTY CLAIM"), including any claim against an Indemnitee as a supplier of
goods or services to the Partnership or any claim against MMT in its capacity as
licensor to the Partnership pursuant to the MMT License Agreement.
Notwithstanding the foregoing, the Partnership shall not have to indemnify any
Indemnitee with respect to any Losses pursuant to this Article 15 to the extent
(x) such Losses are attributable to the gross negligence or willful misconduct
of such Indemnitee, (y) to the extent the applicable Third Party Claim is
subject to the indemnification obligations of MMT or the Partnership under
Sections 10.3 or 10.4 of the MMT License Agreement or (z) to the extent such
Losses are attributable to a breach by such Indemnitee of its obligations under
this Agreement or any of the Related Agreements or any other agreement entered
into pursuant to this Agreement or any Related Agreement (including without
limitation any warranty made by MMT in connection with sales of goods pursuant
to Section 9.5 of the MMT License Agreement). The Partnership 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
Partnership shall consult with the Indemnitees in connection with all material
issues relating to such defense and shall consult with 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
the Partnership does not undertake to oppose or defend any such action within
ninety (90) days after the Partnership becomes aware of such Third Party Claim,
the Indemnitees will have the right to undertake the defense of such claim. In
the event that an Indemnitee undertakes the defense of such claim, such
Indemnitee shall consult with the Partnership in connection with all material
issues relating to such opposition or defense and shall consult with the
Partnership prior to commencing the same and shall consider any recommendations
by the Partnership with respect to the conduct and settlement or compromise
thereof and any reasonable alternative resolutions of the Third Party Claim. If
the Indemnitees undertake to oppose or defend any Third Party Claim pursuant to
the procedure provided for in this Article 15, the Partnership shall bear all
costs of such defense. Any indemnification pursuant to this Article 15 shall be
solely out of the assets of the Partnership and shall not be a personal
obligation of any Partner, including any Limited Partner.

          ----------------

     (a)  Subject to the terms and conditions of this Agreement, MMT hereby
          grants to the Partnership:

          (i)  a non-transferable royalty-bearing exclusive license (including
               the fact that MMT, its Affiliates and licensees are likewise
               excluded except for those activities permitted under Sections 3.1
               or 3.2)) under the MMT Licensed Property (other than the Licensed
               Trademarks) to: (x) establish, own, permit, finance, design,
               engineer, construct, start-up and operate CEP Plants anywhere in
               the world that process Market Feedstocks; (y) establish, own,
               permit, finance, design, engineer, construct, start-up and

               Hazardous Feedstocks, other than Market Feedstocks and Limited
               Feedstocks, generated in the United States, to the extent the
               amount of such Feedstocks processed at any such CEP Plant in any
               year *   ; and (z) establish, own, permit, finance, design,
               engineer, construct, start-up and operate CEP Plants in the
               United States that process, in the aggregate on a cumulative
               basis, that number of tons of Hazardous, Toxic and Superfund
               Feedstocks generated in the United States, other than Market
               Feedstocks and Limited Feedstocks, equal to the number of tons of
               Market Feedstocks processed, in the aggregate on a cumulative
               basis, by * and MMT and their successors in interest pursuant to
               Section 3.1(b) below;

          (ii) a non-transferable royalty-bearing exclusive license (including
               the fact that MMT, its Affiliates and licensees are likewise
               excluded except for those activities permitted under Sections 3.1
               or 3.2) to sublicense the MMT Licensed Property, subject to and
               in accordance with the requirements of Article 8, to third
               parties (including Affiliates and Subsidiaries of LMC and MMT) in
               order to permit them to establish, own, permit, finance,
               construct, start-up and operate CEP Plants located anywhere in
               the world that process Market Feedstocks;

          (iii) a non-transferable royalty-bearing non-exclusive license to use
               the Licensed Trademarks in connection with activities permitted
               under subparagraph (i) or subparagraph (ii) above; and

          (iv) a non-transferable royalty-bearing non-exclusive license to use
               the MMT Licensed Property for its own internal use in connection
               with the activities contemplated by subparagraphs (i)-(iii)
               above.

     (b)  In the event that the environmental remediation or other similar
          responsibility of any governmental organization other than DOE, DoD or
          USEC, or any private entity, is transferred to or assumed by DoD, DOE
          or USEC (such as the DoD's Army Corps of Engineers assuming
          responsibility for remediation of Superfund sites otherwise under the
          jurisdiction of the EPA or a private entity), any Feedstocks nominally
          subject to or related to such responsibility shall not constitute
          "Market Feedstocks" for purposes of this Agreement and the Related
          Agreements.

          Accordingly, the Partnership and its sublicensees shall not be
          entitled to process any such Feedstocks and Section 3.1 below shall
          not prevent MMT and its licensees from processing any such Feedstocks.
          However, subject to any restrictions imposed by MMT's current or
          future agreements with third parties, in the event DoD, DOE or USEC is
          assigned or assumes environmental remediation or similar
          responsibility from a government agency with respect to all of such
          government agency's facilities or otherwise assumes all of the
          environmental remediation or similar responsibility of such government
          agency, MMT shall give the Partnership a right of first offer,
          pursuant to terms and procedures equivalent to those in Section 3.2,
          with respect to any such Feedstocks.

     (c)  To the extent that the environmental remediation or similar
          responsibility currently under the control of DOE, DoD or USEC is
          assigned to or assumed by any other government agency (a "SUCCESSOR
          AGENCY"), then the Partnership and its sublicensees
          shall be permitted to process the same type of Feedstocks with respect
          to such Successor Agency as those which the Partnership and its
          sublicensees could process prior to such transfer to the Successor
          Agency and MMT's restrictions under Section 3.1 shall be extended to
          such Successor Agency.

     (d)  MMT further agrees to include within the licenses granted pursuant to
          Section 2.1 all Intellectual Property acquired by MMT or, subject to
          Section 2.2, licensed to MMT, after the date of this Agreement not
          already then subject to such licenses by the terms hereof, if such
          Intellectual Property is being commercialized by MMT for the Treatment
          or Recycling (as such terms are defined in the Restructuring
          Agreement) of Feedstocks or other wastes in a manner which (i)
          competes directly with CEP or (ii) involves the Treatment or Recycling
          of Feedstocks or other waste.

     2.2. THIRD PARTY LIMITATIONS ON LICENSE GRANTS. The licenses granted by MMT
pursuant to Section 2.1 above, insofar as they relate to technology, property or
rights that are developed or acquired with or from any third party in the
future, may become subject to any applicable restrictions and consents relating
to such technology, property or rights under any license or similar agreement to
which MMT may in the future become a party. In the event that any such license
or other agreement imposes restrictions that may apply to the transactions
contemplated by this Agreement, MMT will make reasonable efforts to obtain
license rights as contemplated by this Agreement for the Partnership. If MMT is
unable to so obtain such rights, it will cooperate to make available to the
Partnership such rights as the third party is willing to grant to or for the
Partnership. As part of the foregoing, MMT shall use reasonable efforts to
assure that the Partnership enjoys license or other rights no less favorable
with respect to the applicable Intellectual Property acquired from such third
parties than other licensees of MMT generally.

                                      -15-

     2.3. EXTENSION OF LICENSE TO SUBSIDIARIES. The licenses granted in Section
2.1 shall include the right of the Partnership to sublicense its Subsidiaries.
Any such sub-license shall be on terms and conditions satisfactory to each of
MMT, LMC and the Partnership.

     2.4. COMMERCIAL AND TECHNICAL TARGETS AFTER 1998. MMT, LMC and the
Partnership shall meet from time to time as appropriate in 1998 to discuss and
implement appropriate commercial and technical goals for the Partnership after
1998 to replace the commercial and technical goals set forth in Sections 10.3
and 10.4 of the Restructuring Agreement, which are only in effect through 1998.

     3.1. Exclusive Market Obligation of MMT.
          ----------------------------------

     (a)  MMT agrees that, during the term of this Agreement, except pursuant to
          this Agreement and the Related Agreements it shall not either directly
          or indirectly (whether through its Affiliates, as a shareholder,
          partner, or consultant):

          (i)  except to the extent permitted under paragraphs (b), (c) or (d)
               below, own or operate any CEP Plant that processes any Market
               Feedstocks; or

          (ii) except to the extent permitted under paragraphs (b), (c) or (d)
               below, sell or license any CEP Plant pursuant to sale or license
               terms which permit such CEP Plant to process any Market
               Feedstocks.

     (b)  Notwithstanding the provisions of paragraph (a) above, under
          relationships existing as of July 1, 1994 between MMT and

                                        *
                                        -
          or their successors in interest,* and MMT (solely to the extent it
          is acting together with * pursuant to either such relationship) may
          own and operate CEP Plants located in the United States that process
          Market Feedstocks generated in the United States, excluding, however,
          Radioactive or Mixed Market Feedstocks,

          which may not be processed by * or MMT pursuant to this paragraph (b).
          MMT shall determine annually the quantity of any such Feedstocks so
          processed. The Partnership and its sublicensees shall be allowed to
          process, at CEP Plants owned by the Partnership or its sublicensees
          and located in the United States, an amount of Hazardous, Toxic or
          Superfund Feedstocks, other than Limited Feedstocks, that are
          generated in the United States but which are not Market Feedstocks,
          equal to the amount of such Market Feedstocks so processed by * or
          MMT. Any CEP Plants developed by * or MMT, or their successors in
          interest, beyond the scope of the relationships existing as of July 1,
          1994 between MMT and * shall not qualify for the exemption provided by
          this paragraph (b) but instead shall be subject to the provisions of
          paragraph (c) below. MMT has previously disclosed in a writing
          acknowledged by MMC the nature of MMT's relationships with * .

     (c)  Except for any agreement entered into with * or their Subsidiaries
          consistent with the provisions of paragraph (b) above, no agreement
          entered into after July 1, 1994 by MMT with any Person other than the
          Partnership shall permit the applicable licensee to process any Market
          Feedstocks at the CEP Plant to be developed pursuant to such
          agreement. However, to provide some flexibility for unintended
          processing of Market Feedstocks, LMC and the Partnership agree that if
          any such licensee processes Market Feedstocks, generated in the United
          States, at a CEP Plant located in the United States and developed
          pursuant to such agreement, in an amount * , such action will not be
          considered a breach of such agreement. Correspondingly, MMT agrees
          that if the Partnership processes Superfund, Hazardous or Toxic
          Feedstocks generated in the United States, other than Market
          Feedstocks or Limited Feedstocks, at any CEP Plant within the United
          States in an amount * , such action shall not be considered a breach
          of this Agreement.

     (d)  The provisions of this Section 3.1 shall not restrict MMT and its
          licensees from owning, operating, selling, or licensing any CEP Plant
          processing Market Feedstocks to the extent such CEP Plant is developed
          by MMT or its licensees pursuant to Section 8(b) of the Restructuring
          Agreement.

     3.2. Additional Market Segments.
          --------------------------

     (a)  In addition to MMT's obligation under Section 3.1 with respect to DoD,
          DOE or USEC facilities, MMT agrees that, during the term of this
          Agreement, except pursuant to this Agreement and the Related
          Agreements it shall not grant a license to any third party to operate
          CEP Plants serving all facilities under the sole control of any other
          United States federal government agency or authority (the "ADDITIONAL
          MARKET SEGMENTS"), without first offering such opportunity to the
          Partnership pursuant to this Section 3.2. An example of an Additional
          Market Segment would be a proposed license to a third party for CEP
          Plants serving all Department of Agriculture facilities.

     (b)  If MMT wishes to grant a license to a third party as provided in
          paragraph (a) above, it shall provide notice to the Executive
          Committee together with sufficient information to enable the Executive
          Committee to decide whether it wishes to pursue such opportunity
          through the Partnership. MMT shall not be required to have identified
          any particular third party or to have received an offer prior to
          implementing the procedures contemplated by this Section 3.2. The
          Executive Committee shall make its decision as promptly as practicable
          after receipt of such information, but in no event more than sixty
          (60) days after receipt of MMT's first notice, and provide prompt
          written notice of such decision to MMT.

          If the Executive Committee decides that it does not wish to pursue
          such opportunity through the Partnership, MMT shall thereafter be free
          to pursue such opportunity on its own. If the Executive Committee
          decides that it does wish to pursue such opportunity through the
          Partnership, the Partnership and MMT shall negotiate in good faith for
          thirty (30) days and if MMT and the Partnership are able to reach
          agreement within such period on the terms pursuant to which MMT shall
          permit the Partnership to pursue such opportunity, then MMT shall not
          pursue such opportunity outside the Partnership. If, after such
          decision, the Executive Committee decides not to pursue such
          opportunity any further, it shall provide prompt notice thereof to
          MMT, who shall thereafter be free to pursue such opportunity on its
          own outside the Partnership.

     (c)  Notwithstanding the foregoing, if additional capital is required from
          LMC in order for the Partnership to pursue any particular Additional
          Market Segment, such decision to pursue the Additional Market Segment
          shall be made by LMC as opposed to the Executive Committee.

     (d)  Any information disclosed by MMT to the Executive Committee pursuant
          to this Section 3.2 shall be subject to Section 6.2.

                     ---------------------------------------

     4.1. TECHNICAL LIAISONS. MMT and the Partnership have designated one or
more employees to serve as technical liaison (the "TECHNICAL LIAISON") for them
under this Agreement and have notified the other party of the identity and
address of such Technical Liaison. The Technical Liaison will continue to be the
primary interface for all issues under this Agreement relating to technology,
including the access to MMT Licensed Property referred to in Section 4.2 below,
the ongoing program referred to in Section 6.7 relating to confidentiality
concerns, the treatment of Improvements, Related Technology and Relevant LMC
Technology pursuant to Article 7 and the sublicensing program referred to in
Article 8. However, no Technical Liaison shall be authorized to amend or waive
any provision of this Agreement or any Related Agreement. Each of MMT and the
Partnership may change its Technical Liaison at any time and from time to time
during the term of this Agreement by notifying the other party and its Technical
Liaison in writing. Each Technical Liaison may nominate a designee to act on its
behalf by giving a similar notification.

     4.2. Access to Technology.
          --------------------

     (a)  In order to ensure that the Partnership has sufficient access to and
          familiarity with the MMT Licensed Property, the Technical Liaisons
          shall meet from time to time to review and discuss the MMT Licensed
          Property. The Technical Liaisons shall, as appropriate, cause
          appropriate MMT and Partnership employees to attend such meetings. The
          MMT Technical Liaison shall provide the Partnership Technical Liaison
          with such writings, documents, instruments, programs (in object code
          form), information, data, and recordations of or other tangible
          embodiments or manifestations of any portion of the MMT Licensed
          Property as is reasonably requested by the Partnership Technical
          Liaison.

     (b)  All information furnished to the Partnership pursuant to paragraph (a)
          above shall be subject to the confidentiality and other obligations of
          Article 6 and shall be furnished or made available to the Partnership
          in a manner consistent with the procedures contemplated by Article 6.

     5.1. Initiation Fee. Upon execution and delivery of the Original Agreement,
the Partnership paid MMT the amount of seven million, five hundred thousand
dollars ($7,500,000) (the "INITIATION FEE").

     5.2. Operations Fees. The Partnership paid MMT the amount of $6,500,000
(the "OPERATIONS FEE") on the first anniversary of the date of the Original
Agreement.

     5.3. PLANT START-UP FEES. The Partnership shall pay to MMT $2,000,000 for
each of the first, second and third CEP Plants developed by the Partnership or
any sublicensee of the Partnership, payable at the time such CEP Plant first
commences Commercial Operation ("Plant Start-Up Fees"). Each Plant Start-Up Fee
shall be paid on the date due (or, if not a Business Day, on the next succeeding
Business Day) by wire transfer in immediately available funds to an account
designated by MMT at least two (2) Business Days prior to the date of payment.

     5.4. ONGOING ROYALTY. (a) Except as provided in paragraph (b) below, during
the term of this Agreement the Partnership shall pay to MMT with respect to any
fiscal year of the Partnership, within thirty (30) days after the final
preparation of audited financial statements of the Partnership for such fiscal
year, but in no event later than May 30 of the following year, royalty payments
(each a "ROYALTY PAYMENT") calculated as follows:

      (i) with respect to any Gross CEP Revenue attributable to the processing
          of USEC Feedstocks under a sublicense granted by the Partnership to
          any Person in which it does not have an ownership interest, in the
          amount of 15% of the royalty attributable to the processing of USEC
          Feedstocks received from such sublicensee for such fiscal year;

     (ii) with respect to any Gross CEP Revenue attributable to the processing
          of USEC Feedstocks under a sublicense granted by the Partnership to
          any Person in which it has an ownership interest (whether or not a
          Substantial Interest), in the amount of 3.5% of the royalty
          attributable to the processing of USEC Feedstocks received from such
          sublicensee for such fiscal year; and

    (iii) in all other cases, in the amount of 2% of the Gross CEP Revenue for
          such fiscal year, excluding any Gross CEP Revenue subject to Section
          5.5 below and excluding any Gross CEP Revenue attributable to the
          processing of Feedstocks other than Market Feedstocks pursuant to
          separate contractual arrangements between

          the Partnership and MMT for Feedstock processing outside the scope of
          this Agreement;

          provided, however, that the Partnership shall not be required to pay
          any portion of the Royalty Payment for any fiscal year to the extent
          the Partnership does not have sufficient Partnership Cash Flow
          remaining after making any payments required to be made prior to such
          payment pursuant to Section 5.6(b). In the event that an amount equal
          to 50% of Partnership Cash Flow for the applicable fiscal year is
          insufficient, after making any payments required to be made prior to
          such payment pursuant to Section 5.6(b), for any fiscal year to pay in
          full the Royalty Payment due for such fiscal year, then the unpaid
          portion of such Royalty Payment shall be deferred until such time as
          the Partnership has generated sufficient Partnership Cash Flow to make
          all such deferred payments, which the Partnership shall pay at such
          time as provided in Section 5.6(b).

              For purposes of this Section 5.4, "net cash flow" means, with
          respect to any CEP Plant, the total revenues generated by such CEP 
          Plant less the operating costs of such CEP Plant, excluding non-cash
          charges, corporate overhead and other expenses not directly related

     5.5. USEC UP-FRONT FEES. The Partnership shall also pay MMT fifteen percent
(15%) of any initiation or up-front fee it receives with respect to any
sublicense for USEC Feedstocks granted to any Person in which the Partnership
has no ownership interest or has an ownership interest but not a Substantial
Interest. For purposes of applying the aforementioned 15% payment to any such
sublicense fee, MMT and the Partnership shall negotiate in good faith respecting
the anticipated quantities of USEC Feedstocks, as compared to other Market
Feedstocks, to be processed by the CEP Plants to be developed pursuant to the
applicable sublicense, and shall apply the following formula for purposes of
such allocation:

          Where "x" denotes the quantity of USEC Feedstocks and "y" denotes the
     quantity of all other Market Feedstocks covered by the applicable
     sublicense and "z" denotes the total initiation fee paid by the
     sublicensee, the Partnership shall pay MMT in accordance with the following
     formula: (15% of zx)/(x+y).

          financial statements for any fiscal year, but in no event later than
          May 30 of the following year, the Partnership shall deliver to MMT
          copies of the audited financial statements for such fiscal year,
          together with a certificate of the General Manager (the "FEE

               Any such payments shall be made by wire transfer of immediately
               available funds to an account designated by MMT for such purpose
               at least two (2) Business Days prior to the date of payment. Any
               such payment and the acceptance thereof shall be without
               prejudice to the rights of MMT or the Partnership under paragraph
               (d) below.

          (c)  Any portion of any Royalty Payment not paid pursuant to paragraph
               (b) above because of insufficient Partnership Cash Flow shall
               continue to accrue until the delivery of a Fee Certificate for
               the subsequent fiscal year, when it shall become payable pursuant
               to the formula set forth in paragraph (b) above and the level of
               Partnership Cash Flow for such fiscal year.

          (d)  If MMT disputes any amount or calculation set forth in a Fee
               Certificate or the amount or timing of any payment made to MMT,
               then MMT and the Partnership shall resolve such dispute pursuant
               to the Dispute Resolution Agreement.

     5.7. GUARANTY BY LMC. Pursuant to the Limited Guaranty executed and
delivered by LMC pursuant to the Restructuring Agreement, LMC shall
unconditionally guaranty to MMT the payment of the Plant Start-Up Fees.

     5.8. MUTUAL TERMINATION. In the event of any termination by the mutual
agreement of the parties hereto of the business relationship contemplated by
this Agreement and the Related Agreements, then unless otherwise agreed at such
time no further fees shall become payable by the Partnership pursuant to this

                (i) to its directors, officers and employees, its Subsidiaries
                    and their directors, officers and employees, in each case to
                    the extent they have a reasonable need to know the contents
                    thereof and who have agreed in writing with MMT to be bound
                    by the provisions of this Article 6;

                    business activities in a manner such that the disclosure
                    requirements of such statute, rule or regulation or court of
                    competent jurisdiction do not apply, and PROVIDED FURTHER

                    promulgated under the Securities Exchange Act of 1934, as
                    amended); and

               technology and market base (other than with CEP) beyond DoD, DOE
               and USEC, and the possibility that MMT and the Partnership could
               compete outside the Market, the Executive Committee will develop

               disclosed pursuant to paragraphs (b)(ii) and (c)(i) above only on
               a "need to know basis", and in particular to prevent the
               disclosure of MMT Confidential Information to Partnership
               personnel (other than the Partnership's executive management or
               their Advisors) who are responsible for developing, marketing, or
               selling technologies which are competitive with MMT or CEP.

10.4. In the event of any claim which combines elements of both an MMT
Infringement Claim and a Partnership Infringement Claim, MMT and the Partnership
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 Partnership Infringement Claim.

                              AMENDED AND RESTATED
                             STOCKHOLDERS AGREEMENT
                             ----------------------


     THIS AMENDED AND RESTATED STOCKHOLDERS AGREEMENT (the "Agreement") has been
made and entered into as of this 30th day of April, 1996, by and among M4
Environmental Management Inc., a Delaware corporation (the "Corporation"),
Martin Marietta Environmental Holdings, Inc., a Delaware corporation ("LMC
Sub"), and MMT Federal Holdings Inc., a Delaware corporation ("MMT Sub").

     WHEREAS, the Corporation, LMC Sub and MMT Sub entered into a Stockholders
Agreement dated as of August 9, 1994 (the "Original Stockholders Agreement");

     WHEREAS, the Corporation, LMC Sub and MMT Sub desire to enter into this
Agreement as contemplated by the Partnership Restructuring Agreement, dated as
of March 15, 1996 (the "Restructuring Agreement"), between Molten Metal
Technology Inc., a Delaware corporation, Lockheed Martin Corporation, a Maryland
corporation, and M4 Environmental L.P., a Delaware limited partnership (the
"Partnership") only for certain limited purposes;

     WHEREAS, LMC Sub and MMT Sub have organized the Corporation to act as the
sole general partner of the Partnership;

     WHEREAS, the parties hereto desire to provide for the governance of the
Corporation and to set forth in detail their respective rights and duties
relating to the Corporation with respect to the matters set forth herein, and to
amend and restate the Original Stockholders Agreement in its entirety.

     NOW, THEREFORE, in consideration of the foregoing premises, the mutual
covenants herein contained and other good and valuable consideration the receipt
of which is hereby acknowledged, the parties hereby amend and restate the
Original Stockholders Agreement in its entirety and hereby agree as follows:

     1.   EFFECTIVE DATE; TERM. This Agreement shall become effective as of the
date hereof and shall remain in effect until the termination of the
Restructuring Agreement, or the dissolution of the Corporation, whichever sooner
occurs.

     2.   STOCK SUBSCRIPTION. The Corporation has sold to each of LMC Sub and 
MMT Sub, and each of LMC Sub and MMT Sub have purchased from the Corporation, 
the number of shares of Class A or Class B Common Stock, $.01 par value, of the
Corporation (the "Shares") set forth opposite the name of such stockholder on
the signature page of this Agreement, at a purchase price of $1.00 per share
which was paid as of the date of the Original Stockholders Agreement. The
Corporation has delivered certificates for the Shares to the respective
purchasers thereof against payment to the Corporation therefor in cash. The


<PAGE>   182

Corporation has paid all expenses in connection with the preparation, issuance
and delivery of the Shares and the certificates therefor.

     3.   RESTRICTIONS ON TRANSFER. Neither the Shares nor any interest thereon
may be sold, transferred, pledged, assigned, hypothecated or otherwise disposed
of (each, a "Disposition") including, without limitation, by operation of law or
otherwise, except as specifically permitted in Section 4 hereof. Any purported
Disposition of any of the Shares in violation of this Section 3 shall be null
and void and of no force and effect as to the proposed transferee.

     4.   CERTAIN PERMITTED DISPOSITIONS. Prior to making any Disposition, the
stockholder desiring to make such Disposition (the "Seller") shall (a) notify
each of the other stockholders (the "Other Holders") and the Corporation in
writing and specify in such notice all of the terms and conditions of the
proposed Disposition, which terms and conditions may only involve a Disposition
of all of the Seller's shares in one transaction to one person; (b) for a period
of thirty (30) calendar days after receipt of such notice, the Other Holders
shall have the right in their sole discretion to object to such proposed
Disposition; and (c) in the event of such objection, no Disposition is
permitted.

     5.   LEGEND AND STOP TRANSFER ORDER. Each holder of the Shares hereby
consents (a) to the placement of an appropriate legend on each certificate
evidencing the Shares subject to this Agreement and on any share certificate
issued at any time in exchange or in substitution for any certificate bearing
such legend; (b) to the entry of a Stop Transfer Order in the Corporation's
stock books, or with the Corporation's stock transfer agent, prohibiting the
transfer of any of the Shares, except in compliance with this Agreement; and (c)
to the refusal by the Corporation to transfer any of the Shares, except in
compliance with this Agreement.

     6.   CERTAIN TECHNOLOGY ISSUES. In the event that at any time prior to 
August 9, 1997 the Board of Directors of the Corporation (the "Board of 
Directors") is deadlocked with respect to the application or deployment of any 
MMT Licensed Property (as defined in the MMT License Agreement) for the 
development of any CEP technology not contemplated by the Business Plan, the 
members of the Board of Directors elected by MMT Sub shall recommend a course of
action in respect of such application or deployment and LMC Sub shall cause the
directors elected by it to vote in favor of such recommended course of action.

     7.   OBLIGATION TO FUND CORPORATION. LMC Sub agrees that it shall fund the
operations of the Corporation, in the Corporation's capacity as general partner
of the Partnership, through August 1, 1999 on the limited basis provided in this
Section 7. The Board of Directors shall request funding from LMC Sub from time
to time (but no less often than annually) to fund the operations of the
Corporation. LMC Sub shall provide the funds requested by the Board of Directors
from time to time, to the extent that the Board of Directors considers such
funding reasonably necessary for the anticipated operations of the Corporation
based on the Business Plan. In no event, however, shall LMC Sub be obligated to
provide more than $20 million in any one fiscal year to the Partnership pursuant
to the Partnership Agreement and the Corporation pursuant to this Agreement, or
more than $75 million in the aggregate from August 9, 1994 (the date of the
Original Stockholders Agreement) through the 



                                      -2-
<PAGE>   183

term of the Partnership Agreement and this Agreement to the Partnership and the
Corporation. Any funding shall be made within ten (10) business days after the
funding request of the Board of Directors by wire transfer to an account
designated by the Corporation at least two (2) business days prior to the due
date. LMC Sub shall have no obligation to provide any additional funding or
financing to the Partnership and the Corporation in excess of the $20
million/$75 million amounts referred to above without its written agreement to
do so. Any contribution made by LMC Sub to the Partnership or the Corporation,
regardless of whether made in its capacity as a limited partner of the
Partnership or as a stockholder of the Corporation not matched by MMT Sub, shall
reduce the foregoing obligation of LMC Sub to make contributions to the
Corporation and the Partnership by an equal amount. It is the intent of the
parties to this Agreement and the Related Agreements that the maximum obligation
of LMC Sub to contribute funds to the Partnership and the Corporation is
expressly limited to provide no more than $20 million in any one fiscal year to
the Partnership and the Corporation or more than $75 million from August 9, 1994
(the date of the Original Stockholders Agreement) through the term of the

                                      -4-


     3.   DISPUTE RESOLUTION PROCEDURES.

     3.1. NOTICE AND INVOCATION OF MEDIATION PROCEDURES. The procedures provided
for by this Agreement shall not apply to any Covered Dispute unless and until
either LMC, the Partnership or MMT (a "REQUESTING PARTY") shall have given
written notice invoking the mediation procedures contained herein to each other
party to the Covered Dispute. Such notice shall specify in reasonable detail the
dispute to which it is intended to apply. Such dispute is hereinafter referred
to as a "NOTICED DISPUTE." The effective date of delivery of such notice is
referred to herein as the "NOTICE DATE."

     3.2. STAY OF LITIGATION UPON ELECTION OF MEDIATION; TOLLING. (a) Each of
the parties hereto agrees that it will not commence any litigation relating to
any Covered Dispute unless prior thereto such party has engaged in the mediation
procedures contemplated by this Section 3 with respect to such Covered Dispute,
except that any party shall be entitled to exercise any remedy in connection
with such Covered Dispute if such party reasonably believes that a statute of
limitations or repose or other similar statute or doctrine will bar its claim or
claims unless a judicial proceeding is commenced or that its rights cannot be
protected other than through immediate injunctive or equitable relief
(collectively, "PERMITTED LITIGATION").

          (b) In the event that the Requesting Party delivers a notice of a
Noticed Dispute, each party hereto shall refrain from commencing any litigation
relating to the Noticed Dispute against any other party to this Agreement and
each of such other party's Subsidiaries, except for any Permitted Litigation.
Such stay shall remain in effect until the earlier of (i) sixty (60) days after
the Notice Date, (ii) completion of the dispute resolution process without
settlement of the Noticed Dispute, or (iii) written agreement by all parties to
discontinue the dispute resolution procedures. If any litigation (other than
Permitted Litigation) is pending at the time of the notice, the parties shall
each take appropriate steps, including all necessary filings with the court
having jurisdiction over such litigation to suspend such litigation for the
period of the stay provided for by this Section 3.2. During the pendency of the
stay of litigation provided for in this Section 3.2, all statutes of limitation
which may be applicable to the Noticed Dispute shall be tolled as between or
among the parties hereto and their respective Subsidiaries.

     3.3.   NEGOTIATION. Within five (5) days after the Notice Date, each party
to such Noticed Dispute shall designate in writing to the other parties the name
of one of its senior executive officers who shall be its "DESIGNATED
REPRESENTATIVE" in the dispute resolution proceedings. Designation by any party
of its Designated Representative shall constitute a representation by such party
that its Designated Representative has full power and authority to bind such
party to any compromise of the Noticed Dispute or any release of rights in
connection therewith. The Designated Representatives shall negotiate in good
faith for ten (10) days to resolve such Noticed Dispute.

     3.4.   THIRD PARTY MEDIATOR. In the event that the Designated 
Representatives are unable to resolve the Noticed Dispute, then within twenty 
(20) days after the Notice Date, the parties shall mutually appoint a neutral 
third party mediator (the "MEDIATOR"). In selecting the Mediator, the parties 
shall select someone with substantial experience in corporate and partnership 
legal 

<PAGE>   199

                                      -5-


matters. If the parties are unable to agree upon the Mediator by the 20th day
following the Notice Date, any party may obtain the appointment of the Mediator
by Endispute/J.A.M.S. or its successor (or if such organization shall no longer
exist or shall refuse to act) by any court of competent jurisdiction. Thereafter
the parties to such Noticed Dispute shall use good faith efforts for thirty (30)
days to mediate the Noticed Dispute using the services of the Mediator. In the
event the parties have not resolved the Noticed Dispute within such thirty (30)
day period, the dispute resolution procedures shall be deemed completed, and any
litigation stay shall terminate.

     3.5.   CONFIDENTIALITY; USE IN LITIGATION.

          3.5.1. All statements, disclosures, submissions, and other
communications made by a party in the course of mediation of a Noticed Dispute
(collectively, "SETTLEMENT INFORMATION") shall be confidential information and
shall not be disclosed to any Person other than the employees, officers, counsel
and consultants directly involved in the Noticed Dispute, and each party in
receipt of Settlement Information shall require all persons to whom it is
permitted to disclose Settlement Information to make a similar nondisclosure
commitment for the benefit of and enforceable by the party providing Settlement
Information. Such nondisclosure obligation shall remain in effect for a period
of six years from the date of disclosure.

          3.5.2. Prior to commencing the mediation process, the parties shall
require the Mediator to sign a confidentiality agreement in which he or she
commits, for the benefit of and on a basis which is enforceable by each party
and its respective Affiliates, that he or she will hold the Settlement
Information confidential and not disclose it to any party other than the parties
and their respective Affiliates, counsel and advisors and agents involved in the
Noticed Dispute except under order of disclosure by a court of competent
jurisdiction or pursuant to a written authorization signed by the party or
parties providing the Settlement Information which is to be disclosed. Each
party agrees that it will not and it will not cause or permit any of its
Affiliates to seek a court order requiring testimony in any court or other
proceeding by the Mediator, with respect to any matter.

          3.5.3. All Settlement Information shall be deemed to be statements
made in the furtherance of settlement negotiations and, as such, shall not be
admissible in any litigation or proceeding; PROVIDED, THAT, no party shall be
prevented from obtaining discovery concerning or offering evidence of facts
disclosed in Settlement Information from sources other than disclosures made in
mediation, to the extent otherwise permissible by law.

     4.   FEES AND EXPENSES OF MEDIATOR. The fees and expenses of the Mediator
shall be divided equally by LMC and MMT.

     5.   SCOPE OF OBLIGATION; SPECIFIC PERFORMANCE. The parties are agreeing to
utilize the settlement procedures outlined above in a good faith effort to
provide for a speedy and economical means of resolving disputes. However, the
parties agree that no party shall be in default or in breach hereof for failure
to adhere to any of the procedures outlined above except that (i) compliance
with the procedures hereof in full when and as required shall be a condition




<PAGE>   200

                                      -6-


precedent to the other party's obligation to continue its participation in the
negotiation and mediation procedures and (ii) either party may obtain an order
of specific performance in respect of the other party's obligation under
Sections 3.2, 3.5.1, 3.5.2, and 3.5.3 and an award of money damages in respect
of Section 4. In addition, nothing herein shall be construed to require any
party to agree to any particular settlement of a dispute. It is the intention of
the parties that this Agreement be purely procedural in nature. Its purpose is
to ensure that the possibilities of settlement are fully explored by the parties
with the aid of a neutral mediator before either party resorts to or continues
the prosecution of litigation.




                                        *

     1. INTRODUCTORY. Molten Metal Technology, Inc., a Delaware corporation (the
"Company"), proposes, subject to the terms and conditions stated herein, to
issue and sell to the several initial purchasers named in Schedule I hereto (the
"Initial Purchasers") $125,000,000 principal amount ("Firm Securities") and also
proposes to grant to the Initial Purchasers an option, exercisable from time to

Securities") of its 5 1/2% Convertible Subordinated Notes Due 2006 to be issued

"Offered Securities".

     A portion of the Offered Securities will be offered and sold in accordance
with Regulation S (the "Regulation S Securities") and a portion of the Offered

     This Agreement, the Indenture and the Registration Rights Agreement are

     2. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents
and warrants to, and agrees with, each of the Initial Purchasers that:

          (a) A confidential preliminary offering memorandum dated April 16, 
     1996 for the offer and sale of the Offered Securities outside the U.S. in

     Preliminary Regulation S Offering Memorandum, the "Preliminary Offering
     Memoranda"), and a confidential offering memorandum dated April 26, 1996
     for the offer and sale of the Offered Securities (the "Offering
     Memorandum") have been prepared by the Company. Such Preliminary Offering
     Memoranda and Offering Memorandum, as supplemented as of the date of this
     Agreement, and the Company's Annual Report are hereinafter collectively

     in the case of the Offering Memorandum, as of the date of this Agreement,
     no Offering Document includes any untrue statement of a material fact or
     omits to state any material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading. The preceding sentence does not

     qualified to do business as a foreign corporation in good standing in all
     other jurisdictions in which its ownership or lease of property or the
     conduct of its business requires such qualification except where the

     business and properties.

          (c) The Company's only subsidiaries are MMT Federal Holdings, Inc. and
     MMT International Holdings, Inc. Each subsidiary of the Company has been

     laws of the jurisdiction of its incorporation, with corporate power and
     authority to own its properties and conduct its business as described in
     the Offering Documents; and each subsidiary of the Company is duly
     qualified to do business as a foreign corporation in good standing in all

     business and properties; all of the issued and outstanding capital stock of
     each subsidiary of the Company has been duly authorized and validly issued
     and is fully paid and nonassessable; and, except as disclosed in the

     Offering Documents, and is duly qualified to do business as a foreign
     partnership in good standing in all other jurisdictions in which its

     and legally binding obligations of the Company and will be enforceable in
     accordance with their terms, subject to (i) bankruptcy, insolvency,
     fraudulent transfer, reorganization, moratorium or similar laws now or
     hereafter in effect relating to creditors' rights generally and (ii)
     general principles of equity.

     Securities will be convertible into the shares of Common Stock, par value
     $.01 per share ("Underlying Shares"), of the Company in accordance with the
     terms of the Indenture; the Underlying Shares initially issuable upon
     conversion of such Offered Securities have been duly authorized and
     reserved for issuance upon such conversion and, when issued upon such
     conversion in accordance with the terms of the Indenture, will be validly
     issued, fully paid and nonassessable; the outstanding Underlying Shares
     have been duly authorized and validly issued, are fully paid

     and nonassessable; the Underlying Shares conform to the description thereof
     contained in the Offering Memorandum, and the stockholders of the Company
     have no preemptive rights with respect to the Offered Securities or the

     in connection with the issuance and sale of the Offered Securities by the
     Company, except as may be required under the Securities Act and the Rules
     and Regulations of the Commission thereunder and state and foreign

     constitute a default under (i) any material statute, rule, regulation or

     made or to be made thereof by them; and except as disclosed in the Offering
     Documents, the Company and its subsidiaries and, to the Company's
     knowledge, M4 hold any leased real or personal property under valid and

     to the revocation or modification of any such certificate, authority or
     permit that, if determined adversely to the Company or any of its
     subsidiaries or M4, would individually or in the aggregate have a material
     adverse effect on the Company and its subsidiaries taken as a whole or on
     M4.

          (m) No labor dispute with the employees of the Company or any
     subsidiary exists or, to the knowledge of the Company, is imminent that

     "intellectual property rights") necessary to conduct the business now
     operated by them, or presently employed by them, and have not received any
     notice of infringement of or conflict with asserted rights of others with
     respect to any intellectual property rights that, if determined adversely
     to the Company or any of its subsidiaries or M4, would individually or in
     the aggregate have a material adverse effect on the Company and its
     subsidiaries taken as a whole or on M4.

          (o) Except as disclosed in the Offering Documents, neither the Company
     nor any of its subsidiaries nor, to the Company's knowledge, M4 is in

     M4; and the Company (in the case of M4, to the Company's knowledge) is not
     aware of any pending investigation which might lead to such a claim.

          (p) Except as disclosed in the Offering Documents, there are no
     pending actions, suits or proceedings against or affecting the Company, any

     in the aggregate, a material adverse effect on the condition (financial or

                                                                               8

     its subsidiaries taken as a whole or on M4, or would materially and
     adversely affect the ability of the Company to perform its obligations
     under the Operative Documents; and no such actions, suits or proceedings
     are, to the Company's knowledge, threatened.

          (q) The financial statements with respect to the Company included in
     the Offering Documents present fairly the financial position of the Company

          (r) Except as disclosed in the Offering Documents, since the date of
     the latest audited consolidated financial statements of the Company
     included in the Offering Documents there has been no material adverse

     operations of the Company and its subsidiaries taken as a whole, and,
     except as disclosed in the Offering Documents, there has been no dividend

     $38 million in indebtedness in connection with a project financing),
     business, properties or results of operations of M4.

          (t) The Company is not and, after giving effect to the offering and
     sale of the Offered Securities and the application of the proceeds thereof
     as described in the Offering Documents, will not be, an "investment

          (v) The offer and sale of the Offered Securities in the manner
     contemplated by this Agreement will be exempt from the registration
     requirements of the Securities Act by reason of Section 4(2) thereof and
     Regulation S ("Regulation S") thereunder; and, unless otherwise required as
     a result of the registration statement to be filed pursuant to the
     Registration Rights Agreement, it is not necessary to qualify an indenture
     in respect of the Offered Securities under the United States Trust
     Indenture Act of 1939, as amended (the "Trust Indenture Act").

          (w) Neither the Company, nor any of its affiliates, nor any person
     acting on its or their behalf (i) has, within the six-month period prior to

     Offered Securities or (ii) has offered or will offer or sell the Offered
     Securities (A) in the United States by means of any form of general
     solicitation or general advertising within the meaning of Rule 502(c) under
     the Securities Act or (B) with respect to any such securities sold in
     reliance on Rule 903 of Regulation S under the Securities Act, by means of
     any directed selling efforts within the meaning of Rule 902(b) of
     Regulation S. The Company, its affiliates and any person acting on its or
     their behalf (other than the Initial Purchasers) have complied and will
     comply with the offering restrictions requirement of Regulation S. The
     Company has not entered and will not enter into any contractual arrangement
     with respect to the distribution of the Offered Securities except for this
     Agreement.

          (x)  The Company is subject to Section 13 or 15(d)

     offering and the closing date, except in either case in accordance with
     Regulation S (or Rule 144A if available) under the Securities Act. Terms

Unless otherwise defined herein, terms used in this subsection (b) have the
meanings given to them by Regulation S.

     (c) Each Initial Purchaser may offer and sell Offered Securities in
definitive, fully registered form to a limited number of institutions, each of
which is reasonably believed by it to be an "accredited investor" within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act (each, an
"Institutional Accredited Investor"); PROVIDED, HOWEVER, that each such
Institutional Accredited Investor executes and delivers to it and the Company,
prior to the consummation of any sale of Offered Securities to such
Institutional Accredited Investor, an Initial Purchaser's Letter in
substantially the form attached as Exhibit A to the Offering Memorandum (an
"Initial Purchaser's Letter").

months after the date of issue of the Offered Securities, and will not offer to
sell in the United Kingdom, by means of any document, any Offered Securities to
persons in the United Kingdom except to persons whose ordinary activities

principal or agent) for the purposes of their businesses or otherwise in
circumstances which have not resulted and will not result in an offer to the
public in the United Kingdom within the meaning of the Public Offers of
Securities Regulations 1995; (ii) it has complied and will comply with all
applicable provisions of the Public Offers of Securities Regulations 1995 and
the Financial Services Act 1986 with respect to anything done by it in relation

(iii) it has only issued or passed on, and will only issue or pass on to any
person, in the United Kingdom, any document received by it in connection with
the issue of the Offered Securities to a person who is of a kind described in

     5. CERTAIN AGREEMENTS OF THE COMPANY. The Company agrees with the Initial
Purchasers that:

     (a) The Company will advise Lazard Freres & Co. LLC promptly of any
proposal to amend or supplement the Offering Documents and will not effect such
amendment or supplementation without its consent, which consent shall not be
unreasonably withheld. If, at any time prior to the completion of the initial
resale of the Offered Securities by the Initial Purchasers, any event occurs as
a result of which the Offering Documents as then amended or supplemented would
include an untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, the Company promptly
will notify Lazard Freres & Co. LLC of such event and promptly will prepare, at
its own expense, an amendment or supplement which will correct such statement or
omission.

     (b) The Company will furnish to Lazard Freres & Co. LLC copies of the
Preliminary Offering Memoranda, the Offering Documents and all amendments and
supplements to such documents, in each case as soon as available and in such
quantities as Lazard Freres & Co. LLC reasonably request, and the Company will
furnish to Lazard Freres & Co. LLC on the date hereof three copies of the
Offering Memorandum signed by a duly authorized officer of the Company, one of
each of which will include the independent accountants' reports therein manually
signed by such independent accountants. At any time when the Company is not
subject to Section 13 or 15(d) of the Exchange Act or is not in compliance with
its obligations thereunder, the Company will promptly furnish or cause to be
furnished to Lazard Freres & Co. LLC and, upon request, to each of the other
Initial Purchasers and, upon request of holders and prospective purchasers of
the Offered Securities, to such holders and purchasers, a reasonable number of
copies of the information required to be delivered to holders and prospective
purchasers of the Offered Securities pursuant to Rule 144A(d)(4) under the
Securities Act (or any successor provision thereto) in order to permit
compliance with Rule 144A in connection with resales by such holders of the
Offered Securities. The Company will pay the expenses of printing and
distributing to the Initial Purchasers all such documents.

     (c) The Company will arrange, in cooperation with the Initial Purchasers
and their counsel, for the 



<PAGE>   16
                                                                              16

qualification of the Offered Securities for sale and the determination of their
eligibility for investment under the laws of such jurisdictions in the United
States as Lazard Freres & Co. LLC designate and will continue such
qualifications in effect so long as required for the resale of the Offered
Securities by the Initial Purchasers; PROVIDED, HOWEVER, that the Company will
not be required to qualify as a foreign corporation or to take any action which
would subject it to general service of process or to taxation in any such
jurisdiction where it is not then so subject.

     (d) During the period of five years after the latest Closing Date, the
Company will furnish to Lazard Freres & Co. LLC and, upon request, to each of
the other Initial Purchasers as soon as practicable after the end of each fiscal
year, a copy of its annual report to stockholders for such year; and the Company
will furnish to Lazard Freres & Co. LLC and, upon request, to each of the other
Initial Purchasers (i) as soon as available, a copy of each report and any
definitive proxy statement of the Company filed with the Commission under the
Exchange Act or mailed to stockholders and (ii) from time to time, such other
publicly available information concerning the Company as Lazard Freres & Co. LLC
may reasonably request.

     (e) During the period of three years after the later of the First Closing
Date and the last Optional Closing Date, the Company will furnish to Lazard
Freres & Co. LLC and, upon request, to each of the other Initial Purchasers and
any holder of Offered Securities a copy of the restrictions on transfer
applicable to the Offered Securities.

     (f) During the period of three years after the later of the First Closing
Date and the last Optional Closing Date, the Company will not, and will not
permit any of its affiliates (as defined in Rule 144 under the Securities Act)
to, resell any of the Offered Securities that have been reacquired by any of
them.

     (g) During the period of three years after the later of the First Closing
Date and the last Optional Closing Date, the Company will not be or become an
open-end investment company, unit investment trust or face-amount certificate
company that is or is required to be registered under Section 8 of the
Investment Company Act and is not, and will not be or become, a closed-end
investment company 


<PAGE>   17
                                                                              17

required to be registered, but not registered, under the Investment Company Act.

     (h) The Company will pay all expenses incidental to the performance of the
Company's obligations (as applicable) under the Operative Documents, including
(i) the fees and expenses of the Trustee and its professional advisers; (ii) all
expenses in connection with the execution, issue, authentication, packaging and
initial delivery of the Offered Securities, the preparation and printing of this
Agreement, Operative Documents, the Offered Securities, the Offering Documents
and amendments and supplements thereto, and any other document relating to the
issuance, offer, sale and delivery of the Offered Securities (other than your
legal (except as provided in the next sentence), accounting, travel or other
fees and expenses); (iii) the cost of qualifying the Offered Securities for
trading in the Private Offerings, Resale and Trading through Automated Linkages
(PORTAL) market and any expenses incidental thereto; and (iv) the cost of any
advertising approved by the Company in connection with the issue of the Offered
Securities (other than a "tombstone" advertisement, if any). The Company will
also pay or reimburse the Initial Purchasers for any reasonable expenses
(including the reasonable fees and disbursements of counsel) incurred in
connection with qualification of the Offered Securities for sale under the laws
of such jurisdictions in the United States as the Initial Purchasers designate
and the printing of memoranda relating thereto, for any fees charged by
investment rating agencies for the rating of the Offered Securities, and for
expenses incurred in distributing the Offering Documents (including any
amendments and supplements thereto). On each Closing Date, in the event that the
Company requests that it be paid in same day funds, the Company will pay to the
Initial Purchasers an amount equal to the additional costs of effecting payment
of the aggregate purchase price of the Offered Securities purchased by the
Initial Purchasers on such Closing Date in same-day funds as compared with
payment in New York Clearing House (next-day) funds.

     (i) In connection with the offering, until Lazard Freres & Co. LLC shall
have notified the Company of the completion of the resale of the Offered
Securities, neither the Company nor any of its affiliates has or will, either
alone or with one or more other persons, bid for or purchase for any account in
which it or any of its affiliates has a beneficial interest any Offered
Securities or attempt to 



<PAGE>   18
                                                                              18

induce any person to purchase any Offered Securities; and neither it nor any of
its affiliates will make bids or purchases for the purpose of creating actual,
or apparent, active trading in, or of raising the price of, the Offered
Securities.

     (j) For a period of 90 days after the date of the Offering Memorandum,
neither the Company nor any of its subsidiaries will offer, sell, contract to
sell, pledge or otherwise dispose of, directly or indirectly, any debt
securities of the Company which mature more than one year from the date of the
Offering Memorandum and which are substantially similar to the Offered
Securities or any shares of Common Stock or securities convertible into or
exercisable or exchangeable for shares of Common Stock or publicly disclose the
intention to make any such offer, sale, pledge or disposal, without the prior
written consent of Lazard Freres & Co. LLC except (w) issuances of Common Stock
pursuant to the conversion or exchange of convertible or exchangeable securities
or the exercise of warrants or options, in each case outstanding on the date
hereof (x) grants of employee stock options or restricted stock pursuant to the
terms of a plan in effect on the date hereof (y) issuance of Common Stock,
subject to restrictions on resale satisfactory to Lazard Freres & Co. LLC, to a
company in a transaction determined by the Company's Board of Directors to
provide a strategic advantage to the Company and (z) the issuance of Common
Stock pursuant to any of the transactions described under "Description of
Capital Stock-Registration Rights" in the Offering Memorandum. Neither the
Company nor any of its subsidiaries will at any time offer, sell, contract to
sell, pledge or otherwise dispose of, directly or indirectly, any securities
under circumstances where such offer, sale, pledge, contract or disposition
would cause the exemption afforded by Section 4(2) of the Securities Act or the
safe harbor of Regulation S thereunder to cease to be applicable to the offer
and sale of the Offered Securities.

     (k) The Company will use its best efforts to cause the Offered Securities
to be eligible for the PORTAL trading system of the National Association of
Securities Dealers, Inc.

     (l) The Company will cause each Restricted Security to bear the legend set
forth in the form of Note included in Article 2 of the Indenture until such
legend shall no longer be necessary or advisable because the 



<PAGE>   19
                                                                              19

Restricted Securities are no longer subject to the restrictions on transfer
described therein.

     (m) The Company will comply with the Registration Rights Agreement and all
agreements set forth in the representation letter of the Company to DTC relating
to the approval of the Offered Securities for "book-entry" transfer.

     6. CONDITIONS OF THE OBLIGATIONS OF THE INITIAL PURCHASERS. The obligations
of the several Initial Purchasers to purchase and pay for the Firm Securities on
the First Closing Date and the Optional Securities on the Optional Closing Date
will be subject (i) to the provisions of Section 9 herein, (ii) in the case of
representations and warranties qualified as to materiality, to the accuracy of
and compliance with such representations and warranties in all respects, and in
the case of representations and warranties not qualified as to materiality, to
the accuracy of and compliance with such representations and warranties in all
material respects taken as a whole, on the part of the Company herein, (iii) to
the accuracy of the statements of Company officers made in any certificate
furnished pursuant to the provisions hereof, (iv) to the performance by the
Company of their obligations hereunder and (v) to the following additional
conditions precedent:

          (a) The Initial Purchasers shall have received two letters, the first
     dated the date of this Agreement and the other dated such Closing Date, of
     Price Waterhouse LLP confirming that they are independent public
     accountants within the meaning of the Securities Act and the applicable
     published rules and regulations thereunder ("Rules and Regulations") and to
     the effect that:

               (i) except as specifically set forth in such letter, in their
          opinion the financial statements and schedules examined by them and
          included in the Offering Documents comply as to form in all material
          respects with the applicable accounting requirements of the Securities
          Act and the related published Rules and Regulations that would apply
          to the Offering Documents if the Offering Documents were prospectuses
          included in a registration statement on Form S-1 under the Securities
          Act;


<PAGE>   20
                                                                              20

              (ii) on the basis of procedures (but not an audit in accordance
          with generally accepted auditing standards) consisting of: (A) reading
          the minutes of meetings of the Board of Directors of the Company and
          its consolidated subsidiaries since December 31, 1995 as set forth in
          the minute books through a specified date not more than five business
          days prior to the date of delivery of such letter; (B) reading the
          unaudited interim financial data for the period from the date of the
          latest balance sheet included in the Offering Memoranda to the date of
          the latest available interim financial data; and (C) making inquiries
          of certain officials of the Company who have responsibility for
          financial and accounting matters regarding the specific items for
          which representations are requested below; nothing has come to their
          attention as a result of the foregoing procedures that caused them to
          believe that: (x) at the date of the latest available interim
          financial data and at a specified date not more than five business
          days prior to the date of delivery of such letter, there was any
          change in the capital stock, increase in long-term debt or any
          decreases in consolidated net current assets (working capital) or
          shareholders' equity of the Company and subsidiaries consolidated as
          compared with amounts shown in the latest balance sheet included in
          the Offering Memoranda or (y) for the periods from January 1, 1996 to
          the date of the latest available financial data and to a specified
          date not more than five business days prior to delivery of such
          letter, there were any decreases, as compared with the fourth quarter
          of 1995, in consolidated revenues, income from operations or in the
          total or per-share amounts of net income, except in all instances for
          changes, increases or decreases which the Offering Memoranda disclose
          have occurred or may occur, or they shall state any specific changes,
          increases or decreases;

             (iii) on the basis of an examination of the financial statements
          included in the Offering Documents and inquiries of officials of the
          Company who have responsibility for financial and accounting matters,
          in their opinion the assumptions of the management of the Company
          provide a reasonable basis for presenting the 



<PAGE>   21
                                                                              21

          effects of the offer and sale of the Offered Securities in the as
          adjusted columns in the tables under the sections "Capitalization" and
          "Summary--Summary Financial Information" in the Offering Documents,
          and the as adjusted columns under the sections "Capitalization" and
          "Summary--Summary Financial Information" give appropriate effect to
          those assumptions and the adjustments have been properly applied to
          the historical amounts in the compilation of those columns; and

                (iv) they have compared specified dollar amounts (or percentages
          derived from such dollar amounts) and other financial information
          contained in the Offering Documents (in each case to the extent that
          such dollar amounts, percentages and other financial information are
          derived from the general accounting records of the Company and its
          subsidiaries subject to the internal controls of the Company's
          accounting system or are derived directly from such records by
          analysis or computation) with the results obtained from inquiries, a
          reading of such general accounting records and other procedures
          specified in such letter and have found such dollar amounts,
          percentages and other financial information to be in agreement with
          such results, except as otherwise specifically set forth in such
          letter.

          (b) The Initial Purchasers shall have received an opinion, dated such
     Closing Date, of Bingham, Dana & Gould LLP, counsel for the Company,
     substantially as set forth in Exhibit A hereto.

          (c) The Initial Purchasers shall have received from Ethan E. Jacks, 
     General Counsel of the Company, to the effect that:

               (i) The execution, delivery and performance by the Company of the
          Operative Documents and the issuance and sale of the Offered
          Securities and compliance with the terms and provisions of the
          Operative Documents and the Offered Securities will not result in a
          breach or violation of any of the terms and provisions of, or
          constitute a default under, or any agreement or instrument to which
          the Company or any such subsidiary is a party or by which the Company
          or any such

          subsidiary is bound or to which any of the properties of the Company
          or any such subsidiary is subject.

               (ii) There are no pending actions, suits or proceedings against
          or affecting the Company or any of its subsidiaries or any of their
          respective properties that if determined adversely would have,
          individually or in the aggregate, a material adverse effect on the
          financial condition, properties, results of operations, business or
          prospects of the Company and its subsidiaries taken as a whole, or
          would materially and adversely affect the ability of the Company to
          perform their obligations under the Operative Documents or which are
          otherwise material in the context of the sale of the Offered
          Securities.

          (d) The Initial Purchasers shall have received an opinion, dated such
     Closing Date, of Hamilton, Brook, Smith & Reynolds, patent counsel for the
     Company, to the effect that:

               (i) the statements in the Offering Memorandum under the captions
          "Risk Factors--Unpredictability of Patent Protection and Proprietary
          Technology," and "Business--Intellectual Property and Proprietary
          Technology," insofar as they relate to provisions of statutes,
          regulations, contracts, agreements, patents, patent applications or
          matters of United States patent law are accurate and correct in all
          material respects;

               (ii) the applications filed by such counsel on behalf of the
          Company with the United States Patent and Trademark Office have been
          duly and adequately filed;

             (iii) the Company owns of record all right, title and interest in
          and to the patents and patent applications described in the Offering
          Memorandum free and clear of any adverse claim known by such counsel
          of any third party. To such counsel's knowledge, the Company has not
          infringed, is not infringing and has not received any notice of
          infringement of any patents of any other person (other than a
          threatened litigation 



<PAGE>   23
                                                                              23

          or action for which the Company has received an opinion of counsel to
          the effect that the chances that such threatened litigation or action
          could be determined adversely to the Company are remote) which might
          have a material and adverse effect on the properties, business,
          financial condition or results of operations of the Company; and

              (iv) to such counsel's knowledge, there is no litigation or
          governmental or other proceeding relating to the intellectual property
          rights, before any court or before or by any public body or board
          (other than the United States Patent and Trademark Office) pending to
          which the Company is a party or threatened against the Company (other
          than a threatened litigation or action for which the Company has
          received an opinion of counsel to the effect that the chances that
          such threatened litigation or action could be determined adversely to
          the Company are remote) which might materially and adversely affect
          the properties, business, financial condition or results of operations
          of the Company; to the counsel's knowledge, the Company has not given
          notice to any third party of any claim of infringement of its patents.

          (e) The Initial Purchasers shall have received from Cravath, Swaine &
     Moore, counsel for the Initial Purchasers, such opinion or opinions, dated
     such Closing Date, with respect to such matters as Lazard Freres & Co. LLC
     may require, and the Company shall have furnished to such counsel such
     documents as they request for the purpose of enabling them to pass upon
     such matters.

          (f) The Initial Purchasers shall have received a certificate dated
     such Closing Date, of the President or any Vice President and a principal
     financial or accounting officer of the Company in which such officers, to
     the best of their knowledge after reasonable investigation, shall state
     that:

               (i) The representations and warranties of the Company in this
          Agreement are true and correct in all material respects on and as of
          such Closing Date with the same effect as if made on such Closing Date
          and the Company has complied in all material respects with all
          agreements and 



<PAGE>   24
                                                                              24

          satisfied in all material respects all conditions on its part to be
          performed or satisfied hereunder at or prior to such Closing Date.

               (ii) Since the date of this Agreement, there has been no material
          adverse change in the financial condition, results of operations,
          business or prospects of the Company and its subsidiaries which would
          result in a material adverse change to the Company or its subsidiaries
          considered as a whole or M4.

          (g) At the First Closing Date, the Company shall have furnished to the
     Initial Purchasers a letter substantially in the form of Exhibit B hereto.

          (h) Subsequent to the execution and delivery of this Agreement and
     prior to the First Closing Date, there shall not have been any downgrading,
     nor shall any notice have been given of any intended or potential
     downgrading or of any review for a possible change that does not indicate
     the direction of the possible change, in the rating accorded any of the
     Company's securities (including the Offered Securities) by any "nationally
     recognized statistical rating organization," as such term is defined for
     purposes of Rule 436(g)(2) under the Act.

     The Company will furnish the Initial Purchasers with such conformed copies
of such opinions, certificates, letters and documents as Lazard Freres & Co. LLC
reasonably requests. Lazard Freres & Co. LLC may in its sole discretion waive
compliance with any conditions to the obligations of the Initial Purchasers
hereunder, whether in respect of such Closing Date or otherwise.

     7. INDEMNIFICATION AND CONTRIBUTION. (a) The Company will indemnify and
hold harmless each Initial Purchaser and each person, if any, who controls such
Initial Purchaser within the meaning of either Section 15 of the Act or Section
20 of the Exchange Act, from and against any and all losses, claims, damages and
liabilities (or actions in respect thereof) (including, without limiting the
foregoing, the reasonable legal and other expenses incurred in connection with
investigating or defending any action, suit or proceeding or any claim asserted,
as such expenses are incurred) arising out of or based on any untrue statement
or alleged untrue statement of a material fact contained in the 



<PAGE>   25
                                                                              25

Offering Documents or any with respect to the Offered Securities, or caused by
any omission or alleged omission to state therein a material fact necessary to
make the statements therein not misleading, except insofar as such losses,
claims, damages, liabilities or expenses are caused by any such untrue statement
or omission or alleged untrue statement or omission made in reliance upon and in
conformity with the information furnished to the Company by the Initial
Purchasers in (i) the first paragraph of page 4 of the Offering Memoranda
concerning over-allotment and stabilization by the Initial Purchasers and (ii)
the second paragraph of the text under the caption "Plan of Distribution" in the
Offering Memorandum; and PROVIDED, HOWEVER, that the Company shall not be liable
to any Initial Purchaser under the indemnity agreement in this Section 7(a) with
respect to any Preliminary Offering Memorandum to the extent that any such loss,
claim, damage or liability of such Initial Purchaser results from the fact that
such Initial Purchaser sold Offered Securities to a person as to whom there was
not sent or given, at or prior to the written confirmation of such sale, a copy
of the Offering Memorandum or of the Offering Memorandum as then amended or
supplemented in any case where such delivery is required by law if the loss,
claim, damage or liability of such Initial Purchaser results from an untrue
statement or omission of a material fact contained in the Preliminary Offering
Memorandum which was corrected in the Offering Memorandum or in the Offering
Memorandum as then amended or supplemented. This indemnity agreement will be in
addition to any liability which the Company may otherwise have to the persons
referred to above in this Section 7(a).

     (b) Each Initial Purchaser agrees, severally and not jointly, to indemnify
and hold harmless the Company and each person, if any, who controls the Company
within the meaning of either Section 15 of the Act or Section 20 of the Exchange
Act, from and against any and all losses, claims, damages and liabilities (or
actions in respect thereof) caused by any untrue statement or alleged untrue
statement of a material fact contained in the Offering Documents or caused by
any omission or alleged omission to state therein a material fact necessary to
make the statements therein not misleading, but only with reference to the
information furnished to the Company by the Initial Purchasers specified in
Section 7(a). This indemnity agreement will be in addition to any liability
which any Initial Purchaser may otherwise have to the persons referred to above
in this Section 7(b).

  
<PAGE>   26
                                                                              26

   (c) In case any action or proceeding (including any governmental or
regulatory investigation or proceeding) shall be instituted involving any person
in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such person (hereinafter called the indemnified party)
shall promptly notify the person against whom such indemnity may be sought
(hereinafter called the indemnifying party) in writing; however, the omission to
so notify the indemnifying party shall relieve the indemnifying party from
liability only to the extent prejudiced thereby. The indemnifying party, upon
request of the indemnified party, shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others that the indemnifying party may
designate and shall pay the fees and disbursements of such counsel related to
such proceeding. In any such action or proceeding any indemnified party shall
have the right to retain its own counsel, but the fees and expenses of such
counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them. It
is understood that the indemnifying party shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for (a)
the reasonable fees and expenses of more than one separate firm (in addition to
any local counsel) for the Initial Purchasers and all persons, if any, who
control any such Initial Purchaser within the meaning of either Section 15 of
the Act or Section 20 of the Exchange Act, and (b) the reasonable fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Company and each person, if any, who controls the Company within the meaning
of either such Section, and that all fees and expenses to be paid pursuant to
each of clauses (a) and (b) of this sentence shall be reimbursed as they are
incurred. In the case of any such separate firm for the Initial Purchasers and
such control persons of the Initial Purchasers, such firm shall be designated in
writing by Lazard Freres & Co. LLC. In the case of any such separate firm for
the Company, and such directors, officers and control persons of the Company,
such firm shall be designated in writing by the Company.

                                                                              27

     (d) If the indemnification provided for in this Section 7 is insufficient
or unavailable to an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and expenses (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company on
the one hand and the Initial Purchasers on the other from the offering of the
Offered Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company on the one hand and the Initial Purchasers on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the Initial Purchasers on the other shall be deemed to be in the
same proportions as the total net proceeds from the offering (before deducting
expenses) received by the Company bear to the total offering discount and
commissions received by the Initial Purchasers. The relative fault of the
Company on the one hand and the Initial Purchasers on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the Initial
Purchasers and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     (e) The Company and each of the Initial Purchasers agree that it would not
be just and equitable if contribution pursuant to Section 7(d) were determined
by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages or liabilities (or actions in respect thereof) referred
to in Section 7(d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the 





<PAGE>   28
                                                                             28

provisions of Section 7(d), in no event shall any such Initial Purchaser be
required to contribute any amount in excess of the amount by which the total
price at which the Offered Securities purchased and resold it exceeds the amount
of any damages which such Initial Purchaser otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     8. DEFAULT OF INITIAL PURCHASERS. If any one or more of the Initial
Purchasers default in their obligations to purchase Offered Securities hereunder
on either the First Closing Date or any Optional Closing Date and the principal
amount of Offered Securities which such defaulting Initial Purchaser or Initial
Purchasers agreed but failed to purchase does not exceed 10% of the aggregate
principal amount of Offered Securities to be purchased on such Closing Date by
all Initial Purchasers, each nondefaulting Initial Purchaser shall be obligated
severally, in proportion to its respective commitments hereunder, to purchase
the Offered Securities which such defaulting Initial Purchaser agreed but failed
or refused to purchase on such date; PROVIDED that in no event shall the
principal amount of Offered Securities that any Initial Purchaser has agreed to
purchase pursuant to Section 3 be increased pursuant to this Section 8 by an
amount in excess of one-ninth of such principal amount of Offered Securities
without the written consent of such Initial Purchaser. If any Initial Purchaser
or Initial Purchasers so default and the aggregate principal amount of Offered
Securities with respect to which such default or defaults occur is more than 10%
of the total principal amount of Offered Securities which the Initial Purchaser
or Initial Purchasers are so obligated to purchase on such date and arrangements
satisfactory to Lazard Freres & Co. LLC and satisfactory to the Company for the
purchase of such Offered Securities by other persons are not made within 36
hours after such default, this Agreement may be terminated by Lazard Freres &
Co. LLC or by the Company without liability on the part of any nondefaulting
Initial Purchaser or the Company, except for the expenses to be paid or
reimbursed by the Company pursuant to Section 9 provided that if such default
occurs with respect to Optional Securities after the First Closing Date, this
Agreement shall not terminate as to the Firm Securities or any Optional
Securities purchased prior to such termination. As 
<PAGE>   29
                                                                              29

used in this Agreement, the term "Initial Purchaser" includes any person
substituted for a Initial Purchaser under this Section. Nothing herein will
relieve a defaulting Initial Purchaser from liability for its default.

     9. SURVIVAL OF CERTAIN REPRESENTATIONS AND OBLIGATIONS. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the Initial Purchasers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation, or statement as to the results thereof, made by or on behalf
of the Initial Purchasers, the Company or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Offered Securities. If this Agreement is
terminated pursuant a Section 8 or if for any reason the purchase of the Offered
Securities by the Initial Purchasers is not consummated, the Company shall
remain responsible for the expenses to be paid or reimbursed by it pursuant to
Section 5 and the respective obligations of the Company and the Initial
Purchasers pursuant to Section 7 shall remain in effect and if any Offered
Securities have been purchased hereunder the representations and warranties in
Section 2 and all obligations under Section 5 shall also remain in effect. If
the purchase of the Offered Securities by the Initial Purchasers is not
consummated for any reason other than solely because of the termination of this
Agreement pursuant to Section 8 or the occurrence of any event specified in
clause (ii) or (iii) of Section 9, the Company will reimburse the Initial
Purchasers for all out-of-pocket expenses (including fees and disbursements of
counsel) reasonably incurred by the Initial Purchasers in connection with the
offering of the Offered Securities.

     10. TERMINATION. This Agreement may be terminated for any reason at any
time prior to delivery and payment for the Securities by the Initial Purchasers
upon the giving of written notice of such termination to the Company, if prior
to such time (i) there has been, since the date of this Agreement, any material
adverse change in the financial condition, earnings, business or prospects of
the Company and its subsidiaries considered as a whole or M4, whether or not
arising in the ordinary course of business, or (ii) there has occurred any
outbreak or escalation of hostilities or other calamity or crisis or material
change in existing national or international financial, political,

economic or securities market conditions, the effect of which is such as to make
it, in the judgment of Lazard Freres & Co. LLC, impracticable or unadvisable to
market the Offered Securities in the manner contemplated in the Offering
Documents or enforce contracts for the sale of the Offered Securities or (iii)
trading in the Common Stock of the Company has been suspended by the Commission
or the Nasdaq/NMS or, trading generally on any of the American Stock Exchange,
the NASDAQ/NMS or the New York Stock Exchange has been suspended, or minimum or
maximum prices for trading have been fixed, or maximum ranges for prices for
securities have been required, by any of such exchanges or by order of the
Commission or any other governmental authority, or if a banking moratorium has
been declared by either Federal or New York authorities. In the event of any
such termination, the provisions of subsection (h) of Section 5 and Sections 7,
8, and 13 shall remain in effect.

     11. NOTICES. All communications hereunder will be in writing and, if sent
to the Initial Purchasers will be mailed, delivered or telegraphed and confirmed

Chief Financial Officer and General Counsel; PROVIDED, HOWEVER, that any notice
to the Initial Purchasers pursuant to Section 7 will be mailed, delivered or
telegraphed and confirmed of Lazard Freres & Co. LLC.

     12. SUCCESSORS. This Agreement will inure to the benefit of and be binding
upon the parties hereto and their respective successors and the controlling
persons referred to in Section 7, and no other person will have any right or
obligation hereunder, except that holders of Offered Securities shall be
entitled to enforce the agreements for their benefit contained in the second and
third sentences of Section 5(b) hereof against the Company as if such holders
were parties thereto.

     13. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

thereof). Owners of beneficial interests in a Global Security will also receive

beneficial interest in a Global Security shall request that the Trustee exchange
such interest for a Restricted Certificated 144A Security, the Depositary shall
surrender such Global Security to the Trustee who shall make a notation on
Schedule A thereof to reduce the principal amount of such Global Security by an

     Agreement, shall be represented by physical certificates issued in
     definitive, fully registered form bearing the Regulation S Legend set forth

     shall bear the Regulation S Securities legend set forth in Exhibit A unless
     removed in accordance with this Section 2.01(c) or Section 2.06(b) hereof;

          (iii) Purchasers of Securities who are not QIBs and did not
     purchase Securities in reliance on Regulation S and who provide a
     certificate in the form of Exhibit B hereto will receive certificated
     Securities in fully registered form bearing the Restricted Securities
     Legend set forth in Exhibit A hereto ("Restricted Accredited Investor
     Securities", and together with the Restricted Certificated 144A Securities
     and the Global Securities, the "Restricted Securities"). Restricted
     Accredited Investor Securities shall bear the Restricted Securities Legend
     set forth on Exhibit A unless removed in accordance with this 2.01(c) or
     Section 2.06(b) hereof.

requirements pertaining to legends on such Restricted Security will cease to
apply, and a Security without legends will be available to the holder of such
Restricted Securities.

transfer or for exchange ("Registrar"), (ii) an office or agency where
Securities may be presented for payment ("Paying Agent") and (iii) an office or
agency where Securities may be presented for conversion ("Conversion Agent").
The Registrar shall keep a register of the Securities and of their transfer and
exchange. The Company may appoint the Registrar, the Paying Agent and the
Conversion Agent and may appoint one or more co-registrars, one or more
additional paying agents and one or more additional conversion agents in such
other locations as it shall determine. The term "Paying Agent" includes any
additional paying agent and the term "Conversion Agent"

                                                                              15

includes any additional conversion agent. The Company may change any Paying
Agent, Registrar, co-registrar or Conversion Agent without prior notice to any
Noteholder. The Company shall notify the Trustee of the name and address of any
Agent not a party to this Indenture. If the Company fails to appoint or maintain
another entity as Registrar, Paying Agent or Conversion Agent, the Trustee shall
act as such. The Company or any of its Affiliates may act as Paying Agent,
Registrar, co-registrar or Conversion Agent.

     SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST. The Company shall
require each Paying Agent other than the Trustee to agree in writing that the
Paying Agent will hold in trust for the benefit of Noteholders or the Trustee
all money held by the Paying Agent for the payment of principal or interest on
the Securities, and will notify the Trustee of any default by the Company in
making any such payment. While any such default continues, the Trustee may
require a Paying Agent to pay all money held by it to the Trustee. The Company
at any time may require a Paying Agent to pay all money held by it to the
Trustee and to account for any money disbursed by it. Upon payment over to the
Trustee, the Paying Agent (if other than the Company or an Affiliate of the
Company) shall have no further liability for the money. If the Company or an
Affiliate of the Company acts as Paying Agent, it shall segregate and hold in a
separate trust fund for the benefit of the Noteholders all money held by it as
Paying Agent.

     SECTION 2.05. NOTEHOLDER LISTS. The Trustee shall preserve in as current a
form as is reasonably practicable the most recent list available to it of the
names and addresses of Noteholders. If the Trustee is not the Registrar, the
Company shall furnish to the Trustee on or before each interest payment date and
at such other times as the Trustee may request in writing a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of Noteholders.

     SECTION 2.06. TRANSFER AND EXCHANGE. Where Securities are presented to the
Registrar or a co-registrar with a request to register a transfer or to exchange
them for an equal principal amount of Securities of other denominations, the
Registrar shall register the transfer or make the exchange if its requirements
for such transactions are met. To permit registrations of transfers and
exchanges, the Company shall issue and the Trustee shall authenticate Securities
at the Registrar's request. No

                                                                              16

service charge shall be made for any registration of transfer or exchange
(except as otherwise expressly permitted herein), but the Company may require
payment of a sum sufficient to cover any transfer tax or similar governmental
charge payable in connection therewith (other than any such transfer tax or
similar governmental charge payable upon exchanges pursuant to Sections 2.10,
3.06 or 11.05 hereof).

     In the event of a partial redemption, the Company shall not be required (i)
to issue, register the transfer of, or exchange Securities during a period
beginning at the opening of business 15 days before the day of any selection of
Securities for redemption under Section 3.02 hereof and ending at the close of
business on the day of selection, or (ii) to exchange or register the transfer
of any Security so selected for redemption in whole or in part, except the
unredeemed portion of any Security being redeemed in part.

     (a) Notwithstanding any provision to the contrary herein, so long as a
Global Security remains outstanding and is held by or on behalf of the
Depositary, transfers of a Global Security, in whole or in part, or of any
beneficial interest therein, shall only be made in accordance with Section
2.01(b) and this Section 2.06(a); PROVIDED, HOWEVER, that beneficial interests
in a Global Security may be transferred to persons who take delivery thereof in
the form of a beneficial interest in the same Global Security in accordance with
the transfer restrictions set forth in the Restricted Securities Legend.

          (i) Except for transfers or exchanges made in accordance with this
     Section 2.06(a), transfers of a Global Security shall be limited to
     transfers of such Global Security in whole, but not in part, to nominees of
     the Depositary or to a successor of the Depositary or such successor's
     nominee.

          (ii) RESTRICTED ACCREDITED INVESTOR SECURITY TO GLOBAL SECURITY OR
     RESTRICTED CERTIFICATED 144A SECURITY. If a holder of a Restricted
     Accredited Investor Security wishes at any time to transfer such Restricted
     Accredited Investor Security to a person who may take delivery thereof in
     the form of either (A) a beneficial interest in a Global Security or (B) a
     Restricted Certificated 144A Security (in each case as indicated by the
     transferor checking box 2 on the Certificate of Transfer on the reverse of
     the 




<PAGE>   25
                                                                              17

     Restricted Accredited Investor Security), such holder may, subject to the
     restrictions on transfer set forth herein and in such Restricted Accredited
     Investor Security, cause the exchange of such Restricted Accredited
     Investor Security for either (A) a beneficial interest in a Global Security
     or (B) a Restricted Certificated 144A Security, as the transferee shall
     determine. Upon receipt by the Trustee, as Registrar, at its office in The
     City of New York of (1) such Restricted Accredited Investor Security, duly
     endorsed as provided herein, and (2) instructions from such holder
     directing the Trustee, as Registrar, to transfer such Restricted Accredited
     Investor Security to a person who will receive either (A) a beneficial
     interest in a Global Security or (B) a Restricted Certificated 144A
     Security, as the transferee shall determine, of the same aggregate
     principal amount as the Restricted Accredited Investor Security to be
     exchanged, such instructions to contain the name of the transferee and the
     authorized denomination or denominations of the Securities to be so issued
     and appropriate delivery instructions therefor, the Trustee, as Registrar,
     shall cancel or cause to be cancelled such Restricted Accredited Investor
     Security and concurrently therewith, (i) the Trustee shall make a notation
     on Schedule A of the Global Security to increase the principal amount of
     such Global Security by an amount equal to the portion of such Restricted
     Accredited Investor Security so exchanged, or (ii) the Company shall
     execute, and the Trustee shall authenticate and make available for
     delivery, one or more Restricted Certificated 144A Securities of the same
     aggregate principal amount equal to the Restricted Accredited Investor
     Security so exchanged, as the case may be.

          (iii) REGULATION S SECURITY TO REGULATION S SECURITY. If a holder of a
     Regulation S Security wishes at any time to transfer such Regulation S
     Security, such holder may, subject to the restrictions on transfer set
     forth herein and in such Regulation S Security, cause the exchange of such
     Regulation S Security for one or more Regulation S Securities of any
     authorized denomination or denominations and of the same aggregate
     principal amount. Upon receipt by the Trustee, as Registrar, at its office
     in the City of New York of (1) such Regulation S Security, (2) instructions
     from such holder directing the 



<PAGE>   26
                                                                              18

     Trustee, as Registrar, to authenticate and deliver one or more Regulation S
     Securities of the same aggregate principal amount as the Regulation S
     Security so exchanged, such instruction to contain the name of the
     transferee and the authorized denomination or denominations of the
     Regulation S Security to be so issued and appropriate delivery
     instructions, (3) if such transfer is prior to the expiration of the
     Restricted Period, a certificate in the form of Exhibit C hereto given by
     the person acquiring the Regulation S Securities for which such interest is
     being exchanged to the effect set forth therein, and (4) such other
     certifications, legal opinions or other information as the Company may
     reasonably require to confirm that such transfer is being made pursuant to
     an exemption from, or in a transaction not subject to, the registration
     requirements under the Securities Act, then the Trustee, as Registrar,
     shall cancel or cause to be cancelled such Regulation S Security and
     concurrently therewith, the Company shall execute, and the Trustee shall
     authenticate and make available for delivery, one or more Regulation S
     Securities of the same aggregate principal amount, in accordance with the
     instructions referred to above.

          (iv) REGULATION S SECURITY TO GLOBAL SECURITY. If a holder of a
     Regulation S Security wishes at any time to transfer such Regulation S
     Security to a person who may take delivery thereof in the form of a
     beneficial interest in a Global Security (as indicated by the transferor
     checking box 2 on the Certificate of Transfer on the reverse of the
     Regulation S Security to be exchanged), such holder may, subject to the
     restrictions on transfer set forth herein and in such Regulation S
     Security, cause the exchange of such Regulation S Security for a beneficial
     interest in a Global Security. Upon receipt by the Trustee, as Registrar,
     at its office in The City of New York of (1) such Regulation S Security,
     duly endorsed as provided herein, and (2) instructions from such holder
     directing the Trustee, as Registrar, to transfer such Regulation S Security
     to a person who will receive a beneficial interest in a Global Security of
     the same aggregate principal amount as the Regulation S Security to be
     exchanged, such instructions to contain the name of the transferee and the
     authorized denomination or denominations of the Securities to be so issued
     and appropriate delivery instructions therefor, then the 




<PAGE>   27
                                                                              19

     Trustee, as Registrar, shall cancel or cause to be cancelled such
     Regulation S Security and concurrently therewith, the Trustee shall make a
     notation on Schedule A of the Global Security to increase the principal
     amount of such Global Security by an amount equal to the portion of such
     Regulation S Security so exchanged.

          (v) GLOBAL SECURITY/RESTRICTED CERTIFICATED 144A SECURITY TO
     REGULATION S SECURITY. If the holder of (i) a beneficial interest in a
     Global Security or (ii) a Restricted Certificated 144A Security wishes at
     any time, upon request to the Trustee, to transfer such beneficial interest
     in such Global Security or such Restricted Certificated 144A Security, as
     the case may be, in accordance with Regulation S, such holder may, subject
     to the restrictions on transfer set forth herein and in such Security,
     cause the exchange of such beneficial interest in such Global Security or
     such Restricted Certificated 144A Security for a Regulation S Security (as
     indicated by the transferor checking box 3 on the Certificate of Transfer
     on the reverse of such Security) upon receipt by the Trustee, as Registrar,
     at its office in the City of New York of (1) in the case of a holder of a
     Restricted Certificated 144A Security, such Restricted Certificated 144A
     Security, duly endorsed as provided herein, (2) instructions from such
     holder directing the Trustee, as Registrar, to transfer such beneficial
     interest in such Global Security or such Restricted Certificated 144A
     Security to a person who will receive a Regulation S Security in an equal
     aggregate principal amount, such instructions to contain the name of the
     transferee and the authorized denomination or denominations of the
     Securities to be so issued and appropriate delivery instructions therefor
     and (3) the transferor shall deliver to the Trustee a certificate in
     substantially the form set forth in Exhibit D hereto. If any person having
     a beneficial interest in a Global Security shall request such a transfer
     and satisfy such conditions, the Trustee shall make a notation on Schedule
     A of such Global Security to reduce the principal amount thereof by an
     amount equal to the portion thereof to be transferred, and concurrently
     therewith, the Company shall execute, and the Trustee shall authenticate
     and make available for delivery, one or more Regulation S Securities of the
     same aggregate principal amount. If any registered 




<PAGE>   28

                                                                              19
     owner of a Restricted Certificated 144A Security shall request such a
     transfer and satisfy such conditions, the Trustee shall cancel such
     Restricted Certificated 144A Security and concurrently therewith, the
     Company shall execute, and the Trustee shall authenticate and make
     available for delivery, one or more Regulation S Securities of the same
     aggregate principal amount.

     (b) (i) Except in connection with a Shelf Registration Statement
contemplated by and in accordance with the terms of the Registration Agreement,
if Restricted Securities are issued upon the transfer, exchange or replacement
of Securities bearing the Restricted Securities Legend or the Regulation S
Securities Legend, as the case may be, set forth in Exhibit A hereto, or if a
request is made to remove the Restricted Securities Legend on Restricted
Securities, the Restricted Securities so issued shall bear the Restricted
Securities Legend, or the Restricted Securities Legend shall not be removed, as
the case may be, unless there is delivered to the Company such satisfactory
evidence, which may include an Opinion of Counsel, as may be reasonably required
by the Company, that neither the legend nor the restrictions on transfer set
forth therein are required to ensure that transfers thereof comply with the
provisions of Rule 144A, Rule 144 or Regulation S under the Securities Act, as
the case may be, or, with respect to such Restricted Securities, that such
Securities are not "restricted" within the meaning of Rule 144 under the
Securities Act. Upon provision of such satisfactory evidence, the Trustee, at
the direction of the Company, shall authenticate and make available for delivery
Securities that do not bear the Restricted Securities Legend.

          (ii) If (a) Regulation S Securities or an interest in a Global
     Security or a Restricted Certificated 144A Security are issued upon
     transfer, exchange or replacement of Regulation S Securities bearing the
     Regulation S Securities Legend set forth in Exhibit A hereto, or (b) if a
     request is made to remove such Regulation S Securities Legend on any
     Regulation S Securities, then (x) the Regulation S Securities so issued
     shall bear the Regulation S Securities Legend and the Global Security or
     the Restricted Certificated 144A Security so issued shall be subject to, or
     bear, the Restricted Securities Legend, as the case may be, or (y) the
     Regulation S Securities Legend 


<PAGE>   29
                                                                              21

     shall not be removed, unless there is delivered to the Company such
     satisfactory evidence, which may include an Opinion of Counsel as may be
     reasonably required by the Company, that neither the legend nor the
     restrictions on transfer set forth therein are required to ensure that
     transfers thereof comply with the provisions of Rule 144A, Rule 144 or
     Regulation S under the Securities Act. Upon provision of such satisfactory
     evidence, the Trustee, at the direction of the Company, shall authenticate
     and make available for delivery Securities that do not bear the Regulation
     S Securities Legend.

     (c) The Trustee shall have no responsibility for any actions taken or not
taken by the Depositary.

     (d) Each holder agrees to indemnify the Company and the Trustee against any
liability that may result from the transfer, exchange or assignment of such
holder's Security in violation of any provision of this Indenture and/or
applicable United States federal or state securities law.

     SECTION 2.07. REPLACEMENT SECURITIES. If the holder of a Security claims
that the Security has been lost, destroyed or wrongfully taken or if such
Security is mutilated and is surrendered to the Trustee, the Company shall issue
and the Trustee shall authenticate a replacement Security if the Trustee's and
the Company's requirements are met. If required by the Trustee or the Company,
an indemnity bond must be sufficient in the judgment of both to protect the
Company, the Trustee, any Agent or any authenticating agent from any loss which
any of them may suffer if a Security is replaced. The Company may charge for its
expenses in replacing a Security.

     In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, or is about to be purchased by the
Company pursuant to Article III hereof, the Company in its discretion may,
instead of issuing a new Security, pay or purchase such Security, as the case
may be.

     Every replacement Security is an additional obligation of the Company.

     SECTION 2.08. OUTSTANDING SECURITIES. The Securities outstanding at any
time are all the Securities 



<PAGE>   30
                                                                              22

authenticated by the Trustee except for those cancelled by it, those delivered
to it for cancellation, and those described in this Section as not outstanding.

     If a Security is replaced, paid or purchased pursuant to Section 2.07
hereof, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced, paid or purchased Security is held by a
bona fide purchaser.

     If Securities are considered paid under Section 4.01 hereof, they cease to
be outstanding and interest on them ceases to accrue.

     A Security does not cease to be outstanding because the Company or an
Affiliate of the Company holds the Security.

     SECTION 2.09. TREASURY SECURITIES. In determining whether the Noteholders
of the required principal amount of Securities have concurred in any direction,
waiver or consent, Securities owned by the Company or an Affiliate of the
Company shall be considered as though they are not outstanding, except that for
the purposes of determining whether the Trustee shall be protected in relying on
any such direction, waiver or consent, only Securities which a Trust Officer of
the Trustee actually knows are so owned shall be so disregarded.

     SECTION 2.10. TEMPORARY SECURITIES. (a) Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities in
exchange for temporary Securities.

     (b) A Global Security deposited with the Depositary or with the Trustee as
custodian for the Depositary pursuant to Section 2.01 shall be transferred to
the beneficial owners thereof in the form of certificated Securities in
compliance with Section 2.01(c) if (i) the Company notifies the Trustee in
writing that the Depositary is no longer willing or able to continue to act as a
depositary and the Company is unable to locate a qualified successor for 90
days, or (ii) the Company, at its option, 




<PAGE>   31
                                                                              23

notifies the Trustee in writing that it elects to cause the issuance of
certificated Securities.

     (c) Any Global Security that is transferable to the beneficial owners
thereof in the form of certificated Securities pursuant to Section 2.01(c) or
this Section 2.10 shall be surrendered by the Depositary to the Trustee located
in The City of New York, to be so transferred, in whole or from time to time in
part, without charge, and the Trustee shall authenticate and make available for
delivery, upon such transfer of each portion of such Global Security, an equal
aggregate principal amount of Securities of authorized denominations in the form
of certificated Securities. Any portion of a Global Security transferred
pursuant to this Section shall be executed, authenticated and delivered only in
denominations of $5,000 and any integral multiple thereof and registered in such
names as the Depositary shall direct. Any Securities in the form of certificated
Securities delivered in exchange for an interest in the Global Security shall,
except as otherwise provided by Section 2.06(b) bear the Restricted Securities
Legend set forth in Exhibit A hereto.

     (d) The registered holder of a Global Security may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a holder is
entitled to take under this Indenture or the Securities.

     (e) In the event of the occurrence of either of the events specified in
Section 2.10(b), the Company will promptly make available to the Trustee a
reasonable supply of certificated Securities in definitive, fully registered
form without interest coupons.

     SECTION 2.11. CANCELLATION. The Company at any time may deliver Securities
to the Trustee for cancellation. The Registrar, Paying Agent and Conversion
Agent shall forward to the Trustee any Securities surrendered to them for
registration of transfer, redemption, conversion, exchange or payment. The
Trustee shall promptly cancel all Securities surrendered for registration of
transfer, redemption, conversion, exchange, payment, replacement or cancellation
and shall return all cancelled Securities to the Company. The Company may not
issue new Securities to replace Securities that it has paid or that have been
delivered to the Trustee for cancellation or that any holder has converted
pursuant to Article V.



<PAGE>   32
                                                                              24

     SECTION 2.12. DEFAULTED INTEREST. If the Company fails to make a payment of
interest on the Securities, it shall pay such defaulted interest plus any
interest payable on the defaulted interest, in any lawful manner. It may pay
such defaulted interest, plus any such interest payable on it, to the persons
who are Noteholders on a subsequent special record date. The Company shall fix
any such record date and payment date. At least 15 days before any such record
date, the Company shall mail to Noteholders a notice that states the record
date, payment date, and amount of such interest to be paid.

     SECTION 2.13. CUSIP NUMBERS. The Company in issuing Securities may use
"CUSIP" numbers (if then generally in use) in addition to serial numbers; if so,
the Trustee shall use such "CUSIP" numbers in addition to serial numbers in
notices of redemption and repurchase as a convenience to holders; PROVIDED,
HOWEVER, that any such notice may state that no representation is made as to the
correctness of such CUSIP number either as printed on the Securities or as
contained in any notice of a redemption or repurchase and that reliance may be
placed only on the serial or other identification numbers printed on the
Securities, and any such redemption or repurchase shall not be affected by any
defect in or omission of such CUSIP number. The Company shall promptly notify
the Trustee of any change in the CUSIP number.

                                   ARTICLE III

                                   Redemption
                                   ----------

     SECTION 3.01. NOTICES TO TRUSTEE. If the Company elects to redeem
Securities pursuant to the optional redemption provision of Section 3.07 hereof,
it shall notify the Trustee of the redemption date and the principal amount of
Securities to be redeemed. The Company shall give each notice provided for in
this Section 3.01 at least 45 days before the redemption date.

     SECTION 3.02. SELECTION OF SECURITIES TO BE REDEEMED. If less than all the
Securities are to be redeemed, the Trustee shall select the Securities to be
redeemed on a pro rata basis, by lot or by such method as the Trustee shall deem
fair and appropriate. The Trustee shall make the selection not more than 60 days
and not less 



<PAGE>   33
                                                                              25

than 30 days before the redemption date from Securities outstanding not
previously called for redemption. The Trustee may select for redemption portions
of the principal of Securities that have denominations larger than $5,000.
Securities and portions of them it selects shall be in amounts of $5,000 or
integral multiples thereof. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly of the Securities or
portions of Securities to be called for redemption.

     If any Security selected for partial redemption is converted in part after
such selection, the converted portion of such Security shall be deemed (so far
as may be) to be the portion to be selected for redemption. The Securities (or
portions thereof) so selected shall be deemed duly selected for redemption for
all purposes hereof, notwithstanding that any such Security is converted in
whole or in part before the mailing of the notice of redemption. Upon any
redemption of less than all the Securities, the Company and the Trustee may
treat as outstanding any Securities surrendered for conversion during the period
15 days next preceding the mailing of a notice of redemption and need not treat
as outstanding any Security authenticated and delivered during such period in
exchange for the unconverted portion of any Security converted in part during
such period.

     SECTION 3.03. NOTICE OF REDEMPTION. At least 30 days but not more than 60
days before a redemption date, the Company shall mail a notice of redemption to
each holder whose Securities are to be redeemed at such holder's registered
address.

     The notice shall identify the Securities (including CUSIP number) to be
redeemed and shall state:

          (a) the redemption date;

          (b) the redemption price;

          (c) if any Security is being redeemed in part, (i) the portion of the
     principal amount of such Security to be redeemed (ii) the last date on
     which exchanges or registration of transfers of Securities may be made
     pursuant to Section 2.06 hereof and that, after the redemption date, upon
     cancellation of such 



<PAGE>   34
                                                                              26

     Security, a new Security or Securities in principal amount equal to the
     unredeemed portion will be issued in the name of the holder thereof;

          (d) the name and address of the Paying Agent;

          (e) that Securities called for redemption must be surrendered to the
     Paying Agent to collect the redemption price plus accrued interest;

          (f) that, unless the Company defaults in making such redemption
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Securities called for
     redemption ceases to accrue on and after the redemption date; and

          (g) the paragraph of the Securities pursuant to
     which the Securities called for redemption are being
     redeemed.

     Such notice shall also state the current Conversion Price and the date on
which the right to convert such Securities or portions thereof into Common Stock
of the Company will expire.

     At the Company's request, the Trustee shall give notice of redemption in
the Company's name and at its expense.

designated for and sufficient to pay all principal, interest and Additional
Amounts, if any, then due and such Paying Agent is not prohibited from paying
such money to the Noteholders on that date pursuant to the terms of this
Indenture. To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace period) at the
rate borne by the Securities, compounded semiannually.

     SECTION 4.02. SEC REPORTS. Whether or not required by the rules and
regulations of the SEC, so long as any Securities are outstanding, the Company
will file with the SEC and furnish to the Trustee and, if requested, to the
holders of Securities all quarterly and annual financial information required to

"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and, with respect to annual information only, a report thereon by
the Company's certified independent accountants.

     Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     SECTION 4.03. COMPLIANCE CERTIFICATE. The Company shall deliver to the
Trustee, within 120 days after the end of each fiscal year of the Company, an
Officers' Certificate stating that a review of the activities of the Company and
its Subsidiaries during the preceding fiscal year has been made under the
supervision of the signing 



<PAGE>   39
                                                                              31

Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under, and complied with the covenants
and conditions contained in, this Indenture, and further stating, as to each
such Officer signing such certificate, that to the best of his knowledge the
Company has kept, observed, performed and fulfilled each and every covenant, and
complied with the covenants and conditions contained in this Indenture and is
not in default in the performance or observance of any of the terms, provisions
and conditions hereof (or, if a Default or Event of Default shall have occurred,
describing all such Defaults or Events of Default of which he may have
knowledge) and that to the best of his knowledge no event has occurred and
remains in existence by reason of which payments on account of the principal or
of interest, if any, on the Securities are prohibited.

     One of the Officers signing such Officers' Certificate shall be either the
Company's principal executive officer, principal financial officer or principal
accounting officer.

     The Company will, so long as any of the Securities are outstanding, deliver
to the Trustee, forthwith upon becoming aware of any Default or Event of Default
an Officers' Certificate specifying such Default or Event of Default.

     Immediately upon the occurrence of any event giving rise to an increase in
the interest rate on the Securities in accordance with Section 11 of the form
thereof or the termination of any such increase, the Company shall give the
Trustee notice of such increase or termination, of the interest rate borne by
the Securities after giving effect to such increase or termination and of the
event giving rise to such increase or termination (such notice to be contained
in an Officers' Certificate), and prior to receipt of such Officers' Certificate
the Trustee shall be entitled to assume that no such increase or termination has
occurred, as the case may be.

     SECTION 4.04. STAY, EXTENSION AND USURY LAWS. The Company covenants (to the
extent that it may lawfully do so) that it will not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of,
any stay, extension or usury law wherever enacted, now or at any time hereafter
in force, which may affect the covenants or the performance of this Indenture;
and the

Company (to the extent it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not, by resort
to any such law, hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law has been enacted.

     SECTION 4.05. CORPORATE EXISTENCE. Subject to Article VII hereof, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its corporate existence and the corporate rights (charter
and statutory), corporate licenses and corporate franchises of the Company;
PROVIDED, HOWEVER, that the Company shall not be required to preserve any such
right, license or franchise, if the Board of Directors of the Company shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and that the loss thereof is not adverse in any
material respect to the Noteholders.

     SECTION 4.06. TAXES. The Company shall, and shall cause each of its
Subsidiaries to, pay prior to delinquency all taxes, assessments and
governmental levies, except as contested in good faith and by appropriate
proceedings.

     SECTION 4.07. DESIGNATED EVENT. (a) Upon the occurrence of a Designated
Event, each holder of Securities shall have the right, in accordance with this
Section 4.07 and Section 3.08 hereof, to require the Company to repurchase all
or any part (equal to $5,000 or an integral multiple thereof) of such holder's
Securities pursuant to the terms of Section 3.08 (the "Designated Event Offer")
at a purchase price equal to 100% of the principal amount thereof, plus accrued
and unpaid interest thereon to the Designated Event Payment Date (the
"Designated Event Payment").

     (b) Within 30 days following any Designated Event, the Company shall mail
to each holder the Company Notice provided by Section 3.08(e).

     SECTION 4.08. ADDITIONAL AMOUNTS. The Company will pay to the holder of any
Security who is a United States Alien (as defined below) such additional amounts
("Additional Amounts") as may be necessary in order that every net payment of
the principal of, premium, if any, and

                                                                              33

interest on such Security, after deduction or withholding for or on account of
any present or future tax, assessment or governmental charge imposed upon or as
a result of such payment by the United States or any political subdivision or
taxing authority thereof or therein, will not be less than the amount provided
for in such Security to be then due and payable; PROVIDED, HOWEVER, that the
foregoing obligation to pay Additional Amounts will not apply to:

          (a) any tax, assessment or other governmental charge which would not
     have been so imposed but for (i) the existence of any present or former
     connection between such holder or the beneficial owner (or between a
     fiduciary, settlor, beneficiary, member, shareholder of or possessor of a
     power over such holder or beneficial owner, if such holder or beneficial
     owner is an estate, a trust, a partnership or a corporation) and the United
     States, including, without limitation, such holder or beneficial owner (or
     such fiduciary, settlor, beneficiary, member, shareholder or possessor)
     being or having been a citizen or resident of the United States or treated
     as a resident thereof, or being or having been engaged in trade or business
     or present therein, or having or having had an office, fixed place of
     business or permanent establishment therein, (ii) such holder's or
     beneficial owner's present or former status as a personal holding company
     or a foreign personal holding company with respect to the United States, a
     foreign private foundation or other foreign tax exempt organization
     described in Section 1443 of the Code, a controlled foreign corporation or
     a passive foreign investment company for United States tax purposes or a
     corporation which accumulates earnings to avoid United States federal
     income tax, (iii) such holder or beneficial owner (or such fiduciary,
     settlor, beneficiary, possessor, member or shareholder) is considered as
     having made an election the effect of which is to make payments of
     principal of and premium, if any, and interest on such Security subject to
     United States federal income tax or (iv) such holder's status as a bank
     whose receipt of interest on such Security is described in Section
     881(c)(3)(A) of the Code;

          (b) any tax, assessment or other governmental charge which would not
     have been so imposed but for the presentation by the holder of such
     Security for payment on a date more than 15 days after the date on which
     such payment became due and payable or the date

                                                                              34

     on which payment thereof is duly provided for, whichever occurs later;

          (c) any estate, inheritance, gift, sales, transfer, personal property
     or similar tax, assessment or governmental charge;

          (d) any tax, assessment or other governmental charge which would not
     have been imposed but for the failure to comply with any certification,
     identification or other reporting requirements concerning the nationality,
     residence, identity or present or former connection with the United States
     of the holder or beneficial owner of such Security if compliance is
     required by statute or by regulation, ruling or other administrative action
     of the United States or any political subdivision or tax authority thereof
     or therein as a precondition to exemption from such tax, assessment or
     other governmental charge;

          (e) any tax, assessment or other governmental charge which is payable
     otherwise than by deduction or withholding from payments of principal of,
     premium, if any, or interest on such Security;

          (f) any tax, assessment or other governmental charge imposed as a
     result of a holder's or beneficial owner's past or present status as a

     Sections 871(h)(3)(B) or 881(c)(3)(B) of the Code;

          (g) any tax, assessment or other governmental charge required to be
     withheld by any Paying Agent from any payment of the principal of, premium,

          (h) any tax, assessment or other governmental charge imposed on a
     holder that is not a beneficial owner of such Security or that is a
     partnership or a fiduciary, but only to the extent that any beneficial
     owner, beneficiary or settlor with respect to such fiduciary or member of
     the partnership would not have been entitled to the payment of Additional
     Amounts had the beneficial owner, beneficiary, settlor or member directly
     received its beneficial or distributive share of payments on such Security;
     or



<PAGE>   43
                                                                              35

          (i) any combination of items (a), (b), (c), (d), (e), (f), (g) and
     (h).

     For purposes of this Section, "United States" means the United States of
America (including the States and the District of Columbia), its territories,
its possessions and other areas subject to its jurisdiction (its "possessions"
including Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, Wake

     Whenever in this Indenture or any Security there is mentioned, in any
context, the payment of the principal of or interest on, or in respect of, any
Security, such mention shall be deemed to include mention of the payment of
Additional Amounts provided for in this Section to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof
pursuant to the provisions of this Section and express mention of the payment of
Additional Amounts (if applicable) in any provisions hereof shall not be
construed as excluding Additional Amounts in those provisions hereof where such
express mention is not made.

<PAGE>   44
                                                                              36

Securities who are United States Aliens without withholding for or on account of
any tax, assessment or other governmental charge described above. If any such
withholding shall be required, then such Officers' Certificate shall specify by
country the amount, if any, required to be withheld on such payments to such
holders and the Company will pay to the Trustee or the Paying Agent the
Additional Amounts required by this Section to be paid in the event of any such
withholding. The Company covenants to indemnify the Trustee and any Paying Agent
for, and to hold them harmless against, any loss, liability or expense arising

                                    ARTICLE V

                                   Conversion
                                   ----------

     SECTION 5.01. CONVERSION PRIVILEGE. A holder of a Security may convert the
principal amount thereof (or any portion thereof that is an integral multiple of
$5,000) into fully paid and nonassessable shares of Common Stock of the Company
at any time after 90 days following the date of original issuance thereof and
prior to the close of business (New York time) on the date of the Security's
maturity at the Conversion Price then in effect, except that, with respect to
any Security called for redemption, such conversion right shall terminate at the
close of business on the Business Day immediately preceding the redemption date,
and except that if a Security is submitted pursuant to the exercise of a
repurchase right pursuant to Section 3.08 and Section 4.07 hereof, the right to
convert such Security will expire upon submission (unless the Company shall
default in making the redemption payment on the Designated Event Payment, as the
case may be when it becomes due, in which case the conversion right shall
terminate on the date such default is cured). The number of shares of Common
Stock issuable upon conversion of a Security is determined by dividing the
principal amount of the Security converted by the conversion price in effect on
the Conversion Date (the "Conversion Price").

     The initial Conversion Price is stated in Section 10 of the Securities and
is subject to adjustment as 


<PAGE>   45
                                                                              37

provided in this Article V.

     Provisions of this Indenture that apply to conversion of all of a Security
also apply to conversion of a portion of it. A holder of Securities is not
entitled to any rights of a holder of Common Stock until such holder of
Securities has converted such Securities into Common Stock, and only to the
extent that such Securities are deemed to have been converted into Common Stock
under this Article V.

     SECTION 5.02. CONVERSION PROCEDURE. To convert a Security, a holder must
satisfy the requirements in Section 10 of the Securities. The date on which the
holder satisfies all of those requirements is the conversion date (the
"Conversion Date"). As soon as practicable after the Conversion Date, the
Company shall deliver to the holder through the Conversion Agent a certificate
for the number of whole shares of Common Stock issuable upon the conversion and
a check for any fractional share determined pursuant to Section 5.03. The person
in whose name the certificate is registered shall become the stockholder of
record on the Conversion Date and, as of such date, such person's rights as a
Noteholder shall cease; PROVIDED, HOWEVER, that no surrender of a Security on
any date when the stock transfer books of the Company shall be closed shall be
effective to constitute the person entitled to receive the shares of Common
Stock upon such conversion as the stockholder of record of such shares of Common
Stock on such date, but such surrender shall be effective to constitute the
person entitled to receive such shares of Common Stock as the stockholder of
record thereof for all purposes at the close of business on the next succeeding
day on which such stock transfer books are open; PROVIDED FURTHER, HOWEVER, that
such conversion shall be at the Conversion Price in effect on the date that such
Security shall have been surrendered for conversion, as if the stock transfer
books of the Company had not been closed.

     No payment or adjustment will be made for accrued and unpaid interest on a
converted Security or for dividends or distributions on shares of Common Stock
issued upon conversion of a Security, but if any holder surrenders a Security
for conversion after the close of business on the record date for the payment of
an installment of interest and prior to the opening of business on the next
interest payment date, then, notwithstanding such conversion, the interest
payable on such interest payment date shall be paid to the holder of such
Security on such record date. In such




<PAGE>   46
                                                                              38

event, such Security, when surrendered for conversion, must be accompanied by
payment in funds acceptable to the Company of an amount equal to the interest
payable on such interest payment date on the portion so converted.

     If a holder converts more than one Security at the same time, the number of
whole shares of Common Stock issuable upon the conversion shall be based on the
total principal amount of Securities converted.

     Upon surrender of a Security that is converted in part, the Trustee shall
authenticate for the holder a new Security equal in principal amount to the
unconverted portion of the Security surrendered.

     SECTION 5.03. FRACTIONAL SHARES. The Company will not issue fractional
shares of Common Stock upon conversion of a Security. In lieu thereof, the
Company will pay an amount in cash based upon the Daily Market Price of the
Common Stock on the trading day prior to the date of conversion.

     SECTION 5.04. TAXES ON CONVERSION. The issuance of certificates for shares
of Common Stock upon the conversion of any Security shall be made without charge
to the converting Noteholder for such certificates or for any tax in respect of
the issuance of such certificates, and such certificates shall be issued in the
respective names of, or in such names as may be directed by, the holder or
holders of the converted Security; PROVIDED, HOWEVER, that in the event that
certificates for shares of Common Stock are to be issued in a name other than
the name of the holder of the Security converted, such Security, when
surrendered for conversion, shall be accompanied by an instrument of transfer,
in form satisfactory to the Company, duly executed by the registered holder
thereof or his duly authorized attorney; and PROVIDED FURTHER, HOWEVER, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any such certificates in a
name other than that of the holder of the converted Security, and the Company
shall not be required to issue or deliver such certificates unless or until the
person or persons requesting the issuance thereof shall have paid to the Company
the amount of such tax or shall have established to the satisfaction of the

     SECTION 5.05. COMPANY TO PROVIDE STOCK. The Company shall at all times
reserve and keep available, free from preemptive rights, out of its authorized
but unissued Common Stock, solely for the purpose of issuance upon conversion of
Securities as herein provided, a sufficient number of shares of Common Stock to
permit the conversion of all outstanding Securities for shares of Common Stock.

     All shares of Common Stock which may be issued upon conversion of the
Securities shall be duly authorized, validly issued, fully paid and
nonassessable when so issued.

     SECTION 5.06. ADJUSTMENT OF CONVERSION PRICE. The Conversion Price shall be
subject to adjustment from time to time as follows:

     (a) In case the Company shall (1) pay a dividend in shares of Common Stock
to holders of Common Stock, (2) make a distribution in shares of Common Stock to
holders of Common Stock, (3) subdivide its outstanding shares of Common Stock
into a greater number of shares of Common Stock or (4) combine its outstanding
shares of Common Stock into a smaller number of shares of Common Stock, the
Conversion Price in effect immediately prior to such action shall be adjusted so
that the holder of any Security thereafter surrendered for conversion shall be
entitled to receive the number of shares of Common Stock which he would have
owned immediately following such action had such Securities been converted
immediately prior thereto. Any adjustment made pursuant to this subsection (a)
shall become effective immediately after the record date in the case of a
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision or combination.

     (b) In case the Company shall issue rights or warrants to all holders of
Common Stock entitling them (for a period commencing no earlier than the record
date for the determination of holders of Common Stock entitled to receive such
rights or warrants and expiring not more than 45 days after such record date) to
subscribe for or purchase shares of Common Stock (or securities convertible into
Common Stock) at a price per share less than the current market price (as
determined pursuant to subsection (f) below) of the Common Stock on such record
date, the Conversion Price shall be adjusted so that the same shall equal the
price determined by multiplying the Conversion Price in effect immediately prior
to such record date by a fraction of which 




<PAGE>   48
                                                                              40

the numerator shall be the number of shares of Common Stock outstanding on such
record date, plus the number of shares of Common Stock which the aggregate
offering price of the offered shares of Common Stock (or the aggregate
conversion price of the convertible securities so offered) would purchase at
such current market price, and of which the denominator shall be the number of
shares of Common Stock outstanding on such record date plus the number of
additional shares of Common Stock offered (or into which the convertible
securities so offered are convertible). Such adjustments shall become effective
immediately after such record date. To the extent that shares of Common Stock
are not delivered pursuant to such rights or warrants, upon the expiration or
termination of such rights or warrants the Conversion Price shall again be
adjusted to be the Conversion Price which would then be in effect had the
adjustments made upon the issuance of such rights or warrants been made on the
basis of delivery of only the number of shares of Common Stock actually
delivered. If such rights or warrants are not so issued, the Conversion Price
shall again be adjusted to be the Conversion Price which would then be in effect
if such date fixed for the determination of stockholders entitled to receive
such rights or warrants had not been fixed.

     (c) In case the Company shall distribute to all holders of Common Stock
shares of any class of Capital Stock of the Company other than Common Stock,
evidences of indebtedness or other assets (other than cash), or shall distribute
to all holders of Common Stock rights or warrants to subscribe for securities
(other than those securities referred to in subsection (b) above), then in each
such case the Conversion Price shall be adjusted so that the same shall equal
the price determined by multiplying the Conversion Price in effect immediately
prior to the date of such distribution by a fraction of which the numerator
shall be the current market price (determined as provided in subsection (f)
below) of the Common Stock on the record date mentioned below less the then fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive evidence of such fair market value and described in a Board
Resolution) of the portion of the assets so distributed or of such subscription
rights or warrants applicable to one share of Common Stock, and of which the
denominator shall be such current market price of the Common Stock. Such
adjustment shall become effective immediately after the record date for the
determination of the holders of Common Stock entitled to receive such





<PAGE>   49
                                                                              41

distribution. Notwithstanding the foregoing, in the event that the Company shall
distribute rights or warrants to subscribe for additional shares of the
Company's Capital Stock (other than the Common Stock referred to in subsection
(b) above) ("Rights") pro rata to holders of Common Stock, the Company may, in
lieu of making any adjustment pursuant to this Section 5.06, make proper
provision so that each holder of a Security who converts such Security (or any
portion thereof) after the record date for such distribution and prior to the
expiration or redemption of the Rights shall be entitled to receive upon such
conversion, in addition to the shares of Common Stock issuable upon such
conversion (the "Conversion Shares"), a number of Rights to be determined as
follows: (i) if such conversion occurs on or prior to the date for the
distribution to the holders of Rights of separate certificates evidencing such
Rights (the "Distribution Date"), the same number of Rights to which a holder of
a number of shares of Common Stock equal to the number of Conversion Shares is
entitled at the time of such conversion in accordance with the terms and
provisions of and applicable to the Rights; and (ii) if such conversion occurs
after the Distribution Date, the same number of Rights to which a holder of the
number of shares of Common Stock into which the principal amount of the Security
so converted was convertible immediately prior to the Distribution Date would
have been entitled on the Distribution Date in accordance with the terms and
provisions of and applicable to the Rights.

     (d) In case the Company shall, by dividend or otherwise, at any time
distribute to all holders of its Common Stock cash (including any distributions
of cash out of current or retained earnings of the Company) in an aggregate
amount that, together with the sum of (x) the aggregate amount of any other
distributions to all holders of its Common Stock made in cash plus (y) all
Excess Payments, in each case made within the 12 months preceding the date fixed
for determining the stockholders entitled to such distribution (the
"Distribution Record Date") and in respect of which no Conversion Price
adjustment pursuant to paragraph (e) of this Section or this paragraph (d) has
been made, exceeds 10% of the product of the current market price per share
(determined as provided in paragraph (f) of this Section) of the Common Stock on
the Distribution Record Date times the number of shares of Common Stock
outstanding on the Distribution Record Date (excluding shares held in the
treasury of the Company), the Conversion Price shall be reduced so that the same
shall equal the price determined by 




<PAGE>   50
                                                                              42

multiplying such Conversion Price in effect immediately prior to the
effectiveness of the Conversion Price reduction contemplated by this paragraph
(d) by a fraction of which the numerator shall be (x) the current market price
per share (determined as provided in paragraph (f) of this Section) of the
Common Stock on the Distribution Record Date less (y) the amount determined by
dividing the aggregate amount of such cash and other consideration (including
any Excess Payments) so distributed in excess of the 10% referred to above by
the shares of Common Stock outstanding on the Distribution Record Date, and the
denominator shall be such current market price per share (determined as provided
in paragraph (f) of this Section) of the Common Stock on the Distribution Record
Date, such reduction to become effective immediately prior to the opening of
business on the day following the Distribution Record Date.

     (e) In case a tender offer or other negotiated transaction made by the
Company or any Subsidiary of the Company for all or any portion of the Common
Stock shall be consummated, if an Excess Payment is made in respect of such
tender offer or other negotiated transaction and the amount of such Excess
Payment, together with the sum of (x) the aggregate amount of all Excess
Payments plus (y) the aggregate amount of all distributions to all holders of
the Common Stock made in cash (specifically including distributions of cash out
of retained earnings), in each case made within the 12 months preceding the date
of payment of such current negotiated transaction consideration or expiration of
such current tender offer, as the case may be (the "Purchase Date"), and as to
which no adjustment pursuant to paragraph (c) or paragraph (d) of this Section
or this paragraph (e) has been made, exceeds 10% of the product of the current
market price per share (determined as provided in paragraph (f) of this Section)
of the Common Stock on the Purchase Date times the number of shares of Common
Stock outstanding (including any tendered shares but excluding any shares held
in the treasury of the Company) on the Purchase Date, the Conversion Price shall
be reduced so that the same shall equal the price determined by multiplying such
Conversion Price in effect immediately prior to the effectiveness of the
Conversion Price reduction contemplated by this paragraph (e) by a fraction of
which the numerator shall be (x) the current market price per share (determined
as provided in paragraph (f) of this Section) of the Common Stock on the
Purchase Date less (y) the amount determined by dividing the aggregate amount of
such Excess Payments and such cash distributions, if any, 





<PAGE>   51
                                                                              43

in excess of the 10% amount referred to above by the shares of Common Stock
outstanding on the Purchase Date, and the denominator shall be such current
market price per share (determined as provided in paragraph (f) of this Section)
of the Common Stock on the Purchase Date, such reduction to become effective
immediately prior to the opening of business on the day following the Purchase
Date.

     (f) The current market price per share of Common Stock on any date shall be
deemed to be the average of the Daily Market Prices for the shorter of (i) 30
consecutive Trading Days ending on the last full trading day on the exchange or
market referred to in determining such Daily Market Prices prior to the time of
determination or (ii) the period commencing on the date next succeeding the
first public announcement of the issuance of such rights or such warrants or
such other distribution or such Excess Payment through such last full trading
day on the exchange or market referred to in determining such Daily Market
Prices prior to the time of determination.

     (g) In any case in which this Section 5.06 shall require that an adjustment
be made immediately following a record date for an event, the Company may elect
to defer, until such event, issuing to the holder of any Security converted
after such record date the shares of Common Stock and other Capital Stock of the
Company issuable upon such conversion over and above the shares of Common Stock
and other Capital Stock of the Company issuable upon such conversion only on the
basis of the Conversion Price prior to adjustment; and, in lieu of the shares
the issuance of which is so deferred, the Company shall issue or cause its
transfer agents to issue due bills or other appropriate evidence of the right to
receive such shares.

     SECTION 5.07. NO ADJUSTMENT. No adjustment in the Conversion Price shall be
required until cumulative adjustments amount to 1% or more of the Conversion
Price as last adjusted; PROVIDED, HOWEVER, that any adjustments which by reason
of this Section 5.07 are not required to be made shall be carried forward and
taken into account in any subsequent adjustment. All calculations under this
Article V shall be made to the nearest cent or to the nearest one-hundredth of a
share, as the case may be. No adjustment need be made for rights to purchase
Common Stock pursuant to a Company plan for reinvestment of dividends or
interest. No adjustment need be made for a change in the par value or no par
value of the Common Stock.



<PAGE>   52
                                                                              44

     SECTION 5.08. OTHER ADJUSTMENTS. (a) In the event that, as a result of an
adjustment made pursuant to Section 5.06 above, the holder of any Security
thereafter surrendered for conversion shall become entitled to receive any
shares of Capital Stock of the Company other than shares of its Common Stock,
thereafter the Conversion Price of such other shares so receivable upon
conversion of any Securities shall be subject to adjustment from time to time in
a manner and on terms as nearly equivalent as practicable to the provisions with
respect to Common Stock contained in this Article V.

     (b) In the event that shares of Common Stock are not delivered after the
expiration of any of the rights or warrants referred to in Section 5.06(b) and
Section 5.06(c) hereof, the Conversion Price shall be readjusted to the
Conversion Price which would otherwise be in effect had the adjustment made upon
the issuance of such rights or warrants been made on the basis of delivery of
only the number of shares of Common Stock actually delivered.

     SECTION 5.09. ADJUSTMENTS FOR TAX PURPOSES. The Company may, at its option,
make such reductions in the Conversion Price, in addition to those required by
Section 5.06 above, as it determines to be advisable in order that any stock
dividend, subdivision of shares, distribution of rights to purchase stock or
securities or distribution of securities convertible into or exchangeable for
stock made by the Company to its stockholders will not be taxable to the
recipients thereof.

     SECTION 5.10. ADJUSTMENTS BY THE COMPANY. The Company from time to time
may, to the extent permitted by law, reduce the Conversion Price by any amount
for any period of at least 20 days, in which case the Company shall give at
least 15 days' notice of such reduction in accordance with Section 5.11, if the
Board of Directors has made a determination that such reduction would be in the
best interests of the Company, which determination shall be conclusive.

     SECTION 5.11. NOTICE OF ADJUSTMENT. Whenever the Conversion Price is
adjusted, the Company shall promptly mail to Noteholders at the addresses
appearing on the Registrar's books a notice of the adjustment and file with the
Trustee an Officers' Certificate briefly stating the facts requiring the
adjustment and the manner of computing 




<PAGE>   53
                                                                              45

it. The certificate shall be conclusive evidence of the correctness of such
adjustment.

     SECTION 5.12. NOTICE OF CERTAIN TRANSACTIONS. In the event that:

     (1) the Company takes any action which would require an adjustment in the
Conversion Price;

     (2) the Company takes any action that would require a supplemental
indenture pursuant to Section 5.13; or

     (3) there is a dissolution or liquidation of the Company;

a holder of a Security may wish to convert such Security into shares of Common
Stock prior to the record date for or the effective date of the transaction so
that he may receive the rights, warrants, securities or assets which a holder of
shares of Common Stock on that date may receive. Therefore, the Company shall
mail to Noteholders at the addresses appearing on the Registrar's books and the
Trustee a notice stating the proposed record or effective date, as the case may
be. The Company shall mail the notice at least 15 days before such date;
however, failure to mail such notice or any defect therein shall not affect the
validity of any transaction referred to in clause (1), (2) or (3) of this
Section 5.12.



<PAGE>   54
                                                                              46

     SECTION 5.13. EFFECT OF RECLASSIFICATIONS, CONSOLIDATIONS, MERGERS OR SALES
ON CONVERSION PRIVILEGE. If any of the following shall occur, namely: (i) any
reclassification or change of outstanding shares of Common Stock issuable upon
conversion of Securities (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or combination), (ii) any consolidation or merger to which the Company is a
party other than a merger in which the Company is the continuing corporation and
which does not result in any reclassification of, or change (other than a change
in name, or par value, or from par value to no par value, or from no par value
to par value or as a result of a subdivision or combination) in, outstanding
shares of Common Stock or (iii) any sale or conveyance of all or substantially
all of the property or business of the Company as an entirety, then the Company,
or such successor or purchasing corporation, as the case may be, shall, as a
condition precedent to such reclassification, change, consolidation, merger,
sale or conveyance, execute and deliver to the Trustee a supplemental indenture
in form satisfactory to the Trustee providing that the holder of each Security
then outstanding shall have the right to convert such Security into the kind and
amount of shares of stock and other securities and property (including cash)
receivable upon such reclassification, change, consolidation, merger, sale or
conveyance by a holder of the number of shares of Common Stock deliverable upon
conversion of such Security immediately prior to such reclassification, change,
consolidation, merger, sale or conveyance. Such supplemental indenture shall
provide for adjustments of the Conversion Price which shall be as nearly
equivalent as may be practicable to the adjustments of the Conversion Price
provided for in this Article V. The foregoing, however, shall not in any way
affect the right a holder of a Security may otherwise have, pursuant to clause
(ii) of the last sentence of subsection (c) of Section 5.06, to receive Rights
upon conversion of a Security. If, in the case of any such consolidation,
merger, sale or conveyance, the stock or other securities and property
(including cash) receivable thereupon by a holder of Common Stock includes
shares of stock or other securities and property of a corporation other than the
successor or purchasing corporation, as the case may be, in such consolidation,
merger, sale or conveyance, then such supplemental indenture shall also be
executed by such other corporation and shall contain such additional provisions
to protect the interests of the holders of the Securities as the Board of
Directors 




<PAGE>   55
                                                                              47

of the Company shall reasonably consider necessary by reason of the foregoing.
The provision of this Section 5.13 shall similarly apply to successive
consolidations, mergers, sales or conveyances.

     In the event the Company shall execute a supplemental indenture pursuant to
this Section 5.13, the Company shall promptly file with the Trustee an Officers'
Certificate briefly stating the reasons therefor, the kind or amount of shares
of stock or securities or property (including cash) receivable by holders of the
Securities upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, sale or conveyance and any
adjustment to be made with respect thereto. Neither the Trustee nor any
Conversion Agent shall have any duty whatsoever to determine whether a
supplemental indenture under this Section 5.13 is required or what the
provisions of such supplemental indenture should be.

     SECTION 5.14. TRUSTEE'S DISCLAIMER. The Trustee has no duty to determine
when an adjustment under this Article V should be made, how it should be made or
what such adjustment should be, but may accept as conclusive evidence of the
correctness of any such adjustment, and shall be protected in relying upon the
Officers' Certificate with respect thereto which the Company is obligated to
file with the Trustee pursuant to Section 5.11. The Trustee makes no
representation as to the validity or value of any securities or assets issued
upon conversion of Securities, and the Trustee shall not be responsible for the
Company's failure to comply with any provisions of this Article V.

     The Trustee shall not be under any responsibility to determine the
correctness of any provisions contained in any supplemental indenture executed
pursuant to Section 5.13, but may accept as conclusive evidence of the
correctness thereof, and shall be protected in relying upon, the Officers'
Certificate with respect thereto which the Company is obligated to file with the
Trustee pursuant to Section 5.13.

                                   ARTICLE VI

                                  Subordination
                                  -------------

     SECTION 6.01. AGREEMENT TO SUBORDINATE. The Company, for itself and its
successors, and each Noteholder, by his acceptance of Securities, agree that the
payment of the principal of or interest, Additional Amounts, if any, or any
other amounts due on the Securities is subordinated in right of payment, to the
extent and in the manner stated in this Article VI, to the prior payment in full
of all existing and future Senior Debt.

     SECTION 6.02. NO PAYMENT ON SECURITIES IF SENIOR DEBT IN DEFAULT. Anything
in this Indenture to the contrary notwithstanding, no payment on account of
principal, premium, if any, or interest on, or redemption, repurchase or other
amounts due on the Securities, and no redemption, purchase, or other acquisition
of the Securities, shall be made by or on behalf of the Company (i) unless full
payment of amounts then due for principal, premium, if any, and interest or
other amounts then due on all Senior Debt has been made or duly provided for
pursuant to the terms of the instrument governing such Senior Debt or (ii) there
shall have occurred an event of default (other than a default in the payment of
principal, premium, if any, sinking funds or interest or other amounts) with
respect to any Senior Debt, as defined therein or in the instrument under which
the same is outstanding, permitting the holders thereof to accelerate the
maturity thereof and written notice of such occurrence shall have been given to
the Company and to the Trustee under this Indenture by any holder or holders of
such Senior Debt and such event of default shall not have been cured or waived
or shall not have ceased to exist.

     In the event that, notwithstanding the provisions of this Section 6.02,
payments are made by or on behalf of the Company in contravention of the
provisions of this Section 6.02, such payments shall be held by the Trustee, any
Paying Agent or the holders, as applicable, in trust for the benefit of, and
shall be paid over to and delivered to, the Representative of the holders of
Senior Debt or the trustee under the indenture or other agreement (if any),
pursuant to which any instruments evidencing any Senior Debt may have been
issued for application to the payment of all Senior Debt ratably according to
the aggregate amounts remaining unpaid to the extent necessary to pay all Senior
Debt in full in accordance with the terms of such Senior 




<PAGE>   57
                                                                              49

Debt, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Debt.

     The Company shall give prompt written notice to the Trustee and any Paying
Agent of any default or event of default under any Senior Debt or under any
agreement pursuant to which any Senior Debt may have been issued.

     SECTION 6.03. DISTRIBUTION ON ACCELERATION OF SECURITIES; DISSOLUTION AND
REORGANIZATION; SUBROGATION OF SECURITIES. (a) If the Securities are declared
due and payable because of the occurrence of an Event of Default, the Company
shall give prompt written notice to the holders of all Senior Debt or to the
trustee(s) or other Representative for such Senior Debt of such acceleration.
The Company may not pay the principal of, interest, Additional Amounts or any
other amounts due on the Securities until five days after such holders or
trustee(s) of Senior Debt receive such notice and, thereafter, the Company may
pay the principal of, interest, Additional Amounts or any other amounts due on
the Securities only if the provisions of this Article VI permit such payment.

     (b) Upon (i) any acceleration of the principal amount due on the Securities
because of an Event of Default or (ii) any distribution of assets of the Company
upon any dissolution, winding up, liquidation or reorganization of the Company
(whether in bankruptcy, insolvency or receivership proceedings or upon an
assignment for the benefit of creditors or any other dissolution, winding up,
liquidation or reorganization of the Company):

          (1) the holders of all Senior Debt shall first be entitled to
receive payment in full of the principal thereof, the interest thereon and any
other amounts due thereon before the Noteholders are entitled to receive payment
on account of the principal of or interest on or any other amounts due on the
Securities;

          (2) any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities (other than
securities of the Company as reorganized or readjusted or securities of the
Company or any other corporation provided for by a plan of reorganization or
readjustment the payment of which is subordinate, at least to the extent
provided in this Article with respect to the Securities, to the payment in full
without diminution or modification by such plan of all

                                                                              50

Senior Debt), to which the holders or the Trustee would be entitled except for
the provisions of this Article, shall be paid by the liquidating trustee or
agent or other person making such a payment or distribution, directly to the
holders of Senior Debt (or their Representatives(s) or trustee(s) acting on
their behalf), ratably according to the aggregate amounts remaining unpaid on
account of the principal of, interest, Additional Amounts and other amounts due
on the Senior Debt held or represented by each, to the extent necessary to make
payment in full of all Senior Debt remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of such Senior Debt; and

          (3) in the event that, notwithstanding the foregoing, any payment
or distribution of assets of the Company of any kind or character, whether in
cash, property or securities (other than securities of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment the payment of which is
subordinate, at least to the extent provided in this Article with respect to the
Securities, to the payment in full without diminution or modification by such
plan of Senior Debt), shall be received by the Trustee or the Noteholders before
all Senior Debt is paid in full, such payment or distribution shall be held in
trust for the benefit of, and be paid over to upon request by a holder of the
Senior Debt, the holders of the Senior Debt remaining unpaid (or their
Representatives) or trustee(s) acting on their behalf, ratably as aforesaid, for
application to the payment of such Senior Debt until all such Senior Debt shall
have been paid in full, after giving effect to any concurrent payment or
distribution to the holders of such Senior Debt.

     Subject to the payment in full of all Senior Debt, the Noteholders shall be
subrogated to the rights of the holders of Senior Debt to receive payments or
distributions of cash, property or securities of the Company applicable to the
Senior Debt until the principal of and interest on the Securities shall be paid
in full and, for purposes of such subrogation, no such payments or distributions
to the holders of Senior Debt of cash, property or securities which otherwise
would have been payable or distributable to Noteholders shall, as between the
Company, its creditors other than the holders of Senior Debt, and the
Noteholders, be deemed to be a payment by the Company to or on account of the
Senior Debt, it being understood that the provisions of this 




<PAGE>   59
                                                                              51

Article are and are intended solely for the purpose of defining the relative
rights of the Noteholders, on the one hand, and the holders of Senior Debt, on
the other hand.

     Nothing contained in this Article or elsewhere in this Indenture or in the
Securities is intended to or shall (i) impair, as between the Company and its
creditors other than the holders of Senior Debt, the obligation of the Company,
which is absolute and unconditional, to pay to the Noteholders the principal of,
interest and Additional Amounts, if any, on the Securities as and when the same
shall become due and payable in accordance with the terms of the Securities,
(ii) affect the relative rights of the Noteholders and creditors of the Company
other than holders of Senior Debt or, as between the Company and the Trustee,
the obligations of the Company to the Trustee, or (iii) prevent the Trustee or
the holders from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article of the holders of Senior Debt in respect of cash, property and
securities of the Company received upon the exercise of any such remedy.

     Upon distribution of assets of the Company referred to in this Article, the
Trustee, subject to the provisions of Section 9.01 hereof, and the Noteholders
shall be entitled to rely upon a certificate of the liquidating trustee or agent
or other person making any distribution to the Trustee or to the Noteholders for
the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article.
The Trustee, however, shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt. Nothing contained in this Article or elsewhere in this
Indenture, or in any of the Securities, shall prevent the good faith application
by the Trustee of any moneys which were deposited with it hereunder, prior to
its receipt of written notice of facts which would prohibit such application,
for the purpose of the payment of or on account of the principal of interest or
Additional Amounts, if any, on the Securities unless, prior to the date on which
such application is made by the Trustee, the Trustee shall be charged with
actual notice under Section 6.03(d) hereof of the facts which would prohibit the
making of such application.

     (c) The provisions of this Article shall not be applicable to any cash,
properties or securities received by the Trustee or by any holder when received
as a holder of Senior Debt and nothing in Section 9.11 hereof or elsewhere in
this Indenture shall deprive the Trustee or such holder of any of its rights as
such holder.

     (d) The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment of money to
or by the Trustee in respect of the Securities pursuant to the provisions of
this Article. The Trustee, subject to the provisions of Section 9.01 hereof,
shall be entitled to assume that no such fact exists unless the Company or any
holder of Senior Debt or any trustee therefor has given notice thereof to the
Trustee. Notwithstanding the provisions of this Article or any other provisions
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any fact which would prohibit the making of any payment of moneys
to or by the Trustee in respect of the Securities pursuant to the provisions in
this Article, unless and until three Business Days after the Trustee shall have
received written notice thereof from the Company or any holder or holders of
Senior Debt or from any trustee therefor; and, prior to the receipt of any such
written notice, the Trustee, subject to the provisions of Section 9.01 hereof,
shall be entitled in all respects conclusively to assume that no such facts
exist; PROVIDED, HOWEVER, that if on a date not less than three Business Days
immediately preceding the date upon which, by the terms hereof, any such moneys
may become payable for any purpose (including, without limitation, the principal
of or interest on any Security), the Trustee shall not have received with
respect to such moneys the notice provided for in this Section 6.03(d), then
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such moneys and to apply the same to
the purpose for which they were received, and shall not be affected by any
notice to the contrary which may be received by it on or after such prior date.

     The Trustee shall be entitled to conclusively rely on the delivery to it of
a written notice by a person representing himself to be a holder of Senior Debt
(or a trustee on behalf of such holder) to establish that such notice has been
given by a holder of Senior Debt (or a trustee on behalf of any such holder or
holders). In the event that the Trustee determines in good faith that further

                                                                              53

evidence is required with respect to the right of any person as a holder of
Senior Debt to participate in any payment or distribution pursuant to this
Article, the Trustee may request such person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Debt held by
such person, the extent to which such person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
person under this Article, and, if such evidence is not furnished, the Trustee
may defer any payment to such person pending judicial determination as to the
right of such person to receive such payment; nor shall the Trustee be charged
with knowledge of the curing or waiving of any default of the character
specified in Section 6.02 hereof or that any event or any condition preventing
any payment in respect of the Securities shall have ceased to exist, unless and
until the Trustee shall have received written notice to such effect.

     (e) The provisions of this Section 6.03 applicable to the Trustee shall
(unless the context requires otherwise) also apply to any Paying Agent for the
Company.

     SECTION 6.04. RELIANCE BY SENIOR DEBT ON SUBORDINATION PROVISIONS. Each
Noteholder by his acceptance thereof acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and a
consideration for each holder of any Senior Debt, whether such Senior Debt was
created or acquired before or after the issuance of the Securities, to acquire
and continue to hold, or to continue to hold, such Senior Debt, and such holder
of Senior Debt shall be deemed conclusively to have relied on such subordination
provisions in acquiring and continuing to hold, or in continuing to hold, such
Senior Debt. Notice of any default in the payment of any Senior Debt, except as
expressly stated in this Article, and notice of acceptance of the provisions
hereof are hereby expressly waived. Except as otherwise expressly provided
herein, no waiver, forbearance or release by any holder of Senior Debt under
such Senior Debt or under this Article shall constitute a release of any of the
obligations or liabilities of the Trustee or holders of the Securities provided
in this Article.

     SECTION 6.05. NO WAIVER OF SUBORDINATION PROVISIONS. Except as otherwise
expressly provided herein, no right of any present or future holder of any
Senior Debt to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or 




<PAGE>   62
                                                                              54

failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof any such holder may have or be otherwise charged with.

     Without in any way limiting the generality of the foregoing paragraph, the
holders of Senior Debt may, at any time and from time to time, without the
consent of, or notice to, the Trustee or the holders of the Securities, without
incurring responsibility to the holders of the Securities and without impairing
or releasing the subordination provided in this Article VI or the obligations
hereunder of the holders of the Securities to the holders of Senior Debt, do any
one or more of the following: (i) change the manner, place or terms of payment
of, or renew or alter, Senior Debt, or otherwise amend or supplement in any
manner Senior Debt or any instrument evidencing the same or any agreement under
which Senior Debt is outstanding; (ii) sell, exchange, release or otherwise
dispose of any property pledged, mortgaged or otherwise securing Senior Debt;
(iii) release any person liable in any manner for the collection of Senior Debt;
and (iv) exercise or refrain from exercising any rights against the Company or
any other person.

     SECTION 6.06. TRUSTEE'S RELATION TO SENIOR DEBT. The Trustee in its
individual capacity shall be entitled to all the rights set forth in this
Article in respect of any Senior Debt at any time held by it, to the same extent
as any holder of Senior Debt, and nothing in Section 9.11 hereof or elsewhere in
this Indenture shall deprive the Trustee of any of its rights as such holder.

     With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations, as are
specifically set forth in this Article, and no implied covenants or obligations
with respect to the holders of Senior Debt shall be read into this Indenture
against the Trustee. The Trustee shall not owe any fiduciary duty to the holders
of Senior Debt but shall have only such obligations to such holders as are
expressly set forth in this Article.

     Each Noteholder by his acceptance thereof authorizes and directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
effectuate 




<PAGE>   63
                                                                              55

the subordination provided in this Article and appoints the Trustee his
attorney-in-fact for any and all such purposes, including, in the event of any
dissolution, winding up or liquidation or reorganization under any applicable
bankruptcy law of the Company (whether in bankruptcy, insolvency or receivership
proceedings or otherwise), the timely filing of a claim for the unpaid balance
of such Noteholder's Securities in the form required in such proceedings and the
causing of such claim to be approved. If the Trustee does not file a claim or
proof of debt in the form required in such proceedings prior to 30 days before
the expiration of the time to file such claims or proofs, then any holder or
holders of Senior Debt or their representative or representatives shall have the
right to demand, sue for, collect, receive and receipt for the payments and
distributions in respect of the Securities which are required to be paid or
delivered to the holders of Senior Debt as provided in this Article and to file
and prove all claims therefor and to take all such other action in the name of
the holders or otherwise, as such holders of Senior Debt or representative
thereof may determine to be necessary or appropriate for the enforcement of the
provisions of this Article.

     SECTION 6.07. OTHER PROVISIONS SUBJECT HERETO. Expect as expressly stated
in this Article, notwithstanding anything contained in this Indenture to the
contrary, all the provisions of this Indenture and the Securities are subject to
the provisions of this Article. However, nothing in this Article shall apply to
or adversely affect the claims of, or payment to, the Trustee pursuant to
Section 9.07. Notwithstanding the foregoing, the failure to make a payment on
account of principal of, interest or Additional Amounts, if any, on the
Securities by reason of any provision of this Article VI shall not be construed
as preventing the occurrence of an Event of Default under Section 8.01.

     SECTION 7.01. COMPANY MAY CONSOLIDATE, ETC., ONLY ON CERTAIN TERMS. The
Company may not consolidate or merge with or into any person (whether or not the
Company is the surviving corporation), or sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of its properties or assets
unless:

          (a) the Company is the surviving or continuing corporation or the
     person formed by or surviving any such consolidation or merger (if other
     than the Company) or the person which acquires by sale, assignment,
     transfer, lease, conveyance or other disposition the properties and assets
     of the Company, is a corporation organized or existing under the laws of
     the United States, any state thereof or the District of Columbia;

          (b) the entity or person formed by or surviving any such consolidation
     or merger (if other than the Company) assumes all the obligations of the
     Company, pursuant to a supplemental indenture in a form reasonably
     satisfactory to the Trustee, under the Securities and this Indenture;

          (c) such sale, assignment, transfer, lease, conveyance or other
     disposition of all or substantially all of the Company's properties or
     assets shall be as an entirety or virtually as an entirety to one person
     and such person shall have assumed all the obligations of the Company,
     pursuant to a supplemental indenture in a form reasonably satisfactory to
     the Trustee, under the Securities and this Indenture;

          (d) immediately after such transaction no Default
     or Event of Default exists; and

          (e) the Company or such person shall have delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that such
     transaction and the supplemental indenture comply with this Indenture and
     that all conditions precedent in this Indenture relating to such
     transaction have been satisfied.

     SECTION 7.02. SUCCESSOR CORPORATION SUBSTITUTED. Upon any consolidation or
merger, or any sale, assignment, transfer, lease, conveyance or other
disposition of all or substantially all of the assets of the Company in
accordance 




<PAGE>   65
                                                                              57

with Section 7.01 hereof, the successor corporation formed by such consolidation
or into or with which the Company is merged or to which such sale, assignment,
transfer, lease, conveyance or other disposition is made shall succeed to, and
be substituted for and may exercise every right and power of, the Company under
this Indenture with the same effect as if such successor Person has been named
as the Company herein; provided, however, that the predecessor Company in the
case of a sale, assignment, transfer, lease, conveyance or other disposition
shall not be released from the obligations under this Indenture and the
Securities.

                                  ARTICLE VIII

                              Defaults and Remedies
                              ---------------------

     SECTION 8.01. EVENTS OF DEFAULT. An "Event of Default" occurs if:

          (a) the Company defaults in the payment of interest, Additional
     Amounts or any other amounts (other than the principal thereof) on any
     Security when the same becomes due and payable, whether or not such
     payments shall be prohibited by Article VI, and the Default continues for a
     period of 30 days after the date due and payable;

          (b) the Company defaults in the payment of the principal of any
     Security when the same becomes due and payable at maturity, upon
     redemption, upon required repurchase or otherwise, whether or not such
     payment shall be prohibited by Article VI;

          (c) the Company fails to observe or perform any covenant or agreement
     contained in Section 4.07 hereof, whether or not such purchase shall be
     prohibited by Article VI;

          (d) the Company fails to observe or perform any other covenant or
     agreement contained in this Indenture or the Securities, required by it to
     be performed, and the Default continues for a period of 60 days after the
     receipt of written notice from the Trustee to the Company or from the
     holders of 25% in aggregate principal amount of the then outstanding
     Securities to the Company and the Trustee stating that such notice is a
     "Notice of Default";



<PAGE>   66
                                                                              58

          (e) there is a default under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or
     evidenced any indebtedness for money borrowed by the Company or any
     Subsidiary of the Company (or the payment of which is guaranteed by the
     Company or any Subsidiary of the Company), whether such indebtedness or
     guarantee now exists or is created after the Issuance Date, which default
     (i) is caused by a failure to pay when due principal of or interest on such
     indebtedness within the grace period provided for in such indebtedness
     (which failure continues beyond any applicable grace period) (a "Payment
     Default") or (ii) results in the acceleration of such indebtedness prior to
     its express maturity and, in each case, the principal amount of any such
     indebtedness, together with the principal amount of any other such
     indebtedness under which there has been a Payment Default or the maturity
     of which has been so accelerated, aggregates $15 million or more;

          (f) failure by the Company or any Subsidiary of the Company to pay
     final judgments (other than any judgment as to which a reputable insurance
     company has accepted full liability) aggregating in excess of $5 million,
     which judgments are not stayed within 60 days after their entry;

          (g) the Company or any Material Subsidiary pursuant to or within the
     meaning of any Bankruptcy Law: (i) commences a voluntary case, (ii)
     consents to the entry of an order for relief against it in an involuntary
     case in which it is the debtor, (iii) consents to the appointment of a
     Custodian of it or for all or substantially all of its property, (iv) makes
     a general assignment for the benefit of its creditors, or (v) makes the
     admission in writing that it generally is unable to pay its debts as the
     same become due; or

          (h) a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that: (i) is for relief against the Company or any
     Material Subsidiary of the Company in an involuntary case, (ii) appoints a
     Custodian of the Company or any Material Subsidiary of the Company or for
     all or substantially all of its property, and the order or decree remains
     unstayed and in effect for 60 days, or 




<PAGE>   67
                                                                              59

     (iii) orders the liquidation of the Company or any Material Subsidiary of
     the Company, and the order or decree remains unstayed and in effect for 60
     days.

     The term "Bankruptcy Law" means Title 11, U.S. Code or any similar federal
or state law for the relief of debtors. The term "Custodian" means any receiver,
trustee, assignee, liquidator or similar official under any Bankruptcy Law.

     SECTION 8.02. ACCELERATION. If any Event of Default (other than an Event of
Default specified in clauses (g) and (h) of Section 8.01 hereof) occurs and is
continuing, the Trustee by notice to the Company, or the Noteholders of at least
25% in principal amount of the then outstanding Securities by notice to the
Company and the Trustee, may declare all the Securities to be due and payable.
Upon such declaration, the principal of, premium, if any, accrued and unpaid
interest and Additional Amounts, if any, on the Securities shall be due and
payable immediately. If an Event of Default specified in clause (g) or (h) of
Section 8.01 hereof occurs, such an amount shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any Noteholder. The Noteholders of a majority in aggregate
principal amount of the then outstanding Securities by notice to the Trustee may
rescind an acceleration and its consequences if all existing Events of Default
have been cured or waived except nonpayment of principal or interest that has
become due solely because of the acceleration.

     SECTION 8.03. OTHER REMEDIES. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest on the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Noteholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

     SECTION 8.04. WAIVER OF PAST DEFAULTS. The Noteholders of a majority in
aggregate principal amount of 




<PAGE>   68
                                                                              60

the then outstanding Securities by notice to the Trustee may on behalf of all
the holders waive an existing Default or Event of Default and its consequences
except a continuing Default or Event of Default in the payment of any Designated
Event Offer Amount or the principal of, or premium, if any, or interest on, any
Security (except a rescission of acceleration of the Securities by the Holders
of at least a majority in aggregate principal amount of the then outstanding
Securities and a waiver of a payment default that resulted from such
acceleration). When a Default or Event of Default is waived, it is cured and
ceases; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

     SECTION 8.05. CONTROL BY MAJORITY. The Noteholders of a majority in
principal amount of the then outstanding Securities may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on it. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture, is
unduly prejudicial to the rights of other Noteholders, or would involve the
Trustee in personal liability.

     SECTION 8.06. LIMITATION ON SUITS. A Noteholder may pursue a remedy with
respect to this Indenture or the Securities only if:

          (a) the Noteholder gives to the Trustee notice of
     a continuing Event of Default;

          (b) the Noteholders of at least 25% in principal amount of the then
     outstanding Securities make a request to the Trustee to pursue the remedy;

          (c) such Noteholder or Noteholders offer to the
     Trustee indemnity satisfactory to the Trustee against
     any loss, liability or expense;

          (d) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of indemnity; and

          (e) during such 60-day period the Noteholders of a majority in
     principal amount of the then outstanding Securities do not give the Trustee
     a direction inconsistent with the request.



<PAGE>   69
                                                                              61

     A Noteholder may not use this Indenture to prejudice the rights of another
Noteholder or to obtain a preference or priority over another Noteholder.

     SECTION 8.07. RIGHTS OF NOTEHOLDERS TO RECEIVE PAYMENT. Notwithstanding any
other provision of this Indenture, the right of any Noteholder to convert such
Noteholder's Security and to receive payment of principal, interest and
Additional Amounts, if any, on such Noteholder's Security, on or after the
respective due dates expressed in such Security, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of the Noteholder made pursuant to this
Section.

     SECTION 8.08. COLLECTION SUIT BY TRUSTEE. If an Event of Default specified
in Section 8.01(a) or (b) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount of principal, interest and Additional Amounts, if any,
remaining unpaid on the Securities and interest on overdue principal and
interest and such further amount as shall be sufficient to cover the costs and,
to the extent lawful, expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

     SECTION 8.09. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Noteholders allowed in any
judicial proceedings relative to the Company, its creditors or its property.
Nothing contained herein shall be deemed to authorize the Trustee to authorize
or consent to or accept or adopt on behalf of any Noteholder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Noteholder thereof, or to authorize the Trustee to vote in
respect of the claim of any Noteholder in any such proceeding.

     SECTION 8.10. PRIORITIES. If the Trustee collects any money pursuant to
this Article, it shall pay out the money in the following order:

          FIRST:  to the Trustee for amounts due under
     Section 9.07 hereof;



<PAGE>   70
                                                                              62

          SECOND:  to the holders of Senior Debt to the
     extent required by Article VI;

          THIRD: to Noteholders for amounts due and unpaid on the Securities for
     principal, interest and Additional Amounts, if any, ratably, without
     preference or priority of any kind, according to the amounts due and
     payable on the Securities for principal, interest and Additional Amounts,
     if any, respectively; and

          FOURTH:  to the Company.

     Except as otherwise provided in Section 2.12 hereof, the Trustee may fix a
record date and payment date for any payment to Noteholders made pursuant to
this Section.

     SECTION 8.11. UNDERTAKING FOR COSTS. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a holder pursuant to Section 8.07 hereof, or a
suit by Noteholders of more than 25% in principal amount of the then outstanding
Securities.

                                   ARTICLE IX

                                     Trustee
                                     -------

     SECTION 9.01. DUTIES OF TRUSTEE. (a) If an Event of Default has occurred
and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in
their exercise, as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs.

          (b) Except during the continuance of an Event of Default: (i) the
Trustee need perform only those duties that are specifically set forth in this
Indenture and no others and (ii) in the absence of bad faith on its part, the



<PAGE>   71
                                                                              63

Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture.
However, in the case of any such certificates or opinions which by any provision
hereof are specifically required to be furnished to the Trustee, the Trustee
shall examine the certificates and opinions to determine whether or not they
conform to the requirements of this Indenture.

     (c) The Trustee may not be relieved from liability for its own negligent
action, its own negligent failure to act, or its own wilful misconduct, except
that: (i) this paragraph does not limit the effect of paragraph (b) of this
Section 9.01; (ii) the Trustee shall not be liable for any error of judgment
made in good faith by a Trust Officer, unless it is proved that the Trustee was
negligent in ascertaining the pertinent facts and (iii) the Trustee shall not be
liable with respect to any action it takes or omits to take in good faith in
accordance with a direction received by it pursuant to Section 8.05 hereof.

     (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b) and (c) of this Section 9.01. No
provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder, or in the exercise of any of its rights or powers, if it
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

     (e) The Trustee may refuse to perform any duty or exercise any right or
power unless it receives indemnity satisfactory to it against any loss,
liability or expense.

     (f) The Trustee shall not be liable for interest on any money received by
it except as the Trustee may agree in writing with the Company. Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.

     SECTION 9.02. RIGHTS OF TRUSTEE. (a) The Trustee may rely on any document
reasonably believed by it to be genuine and to have been signed or presented by
the proper person. The Trustee need not investigate any fact or matter stated in
the document.

     (b) Before the Trustee acts or refrains from acting, it (unless other
evidence be herein specifically prescribed) may require an Officers' Certificate
or an Opinion of Counsel, or both. The Trustee shall not be liable for any
action it takes or omits to take in good faith in reliance on such Officers'
Certificate or Opinion of Counsel.

     (c) The Trustee may act through agents and nominees and shall not be
responsible for the misconduct or negligence of any agent appointed with due
care.

     (d) The Trustee shall not be liable for any action that it takes or omits
to take in good faith, without negligence or wilful misconduct, and that it
reasonably believes to be authorized or within its rights or powers.

     (e) The Trustee shall not be charged with knowledge of any Event of Default
under subsection (c), (d), (e) or (f) of Section 8.01 or of the identity of any
Material Subsidiary unless either (1) a Trust Officer assigned to its corporate
trust department shall have actual knowledge thereof, or (2) the Trustee shall
have received notice thereof in accordance with Section 12.02 hereof from the
Company or any holder.

     (f) The Trustee may consult with counsel of its selection and the advice of
such counsel or any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon.

     (g) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder.

     SECTION 9.03. INDIVIDUAL RIGHTS OF TRUSTEE. The Trustee in its individual
or any other capacity may become the owner or pledgee of Securities and may
otherwise deal with the Company or an Affiliate of the Company with the same
rights it would have if it were not Trustee. Any Agent may do the same with like
rights. However, the Trustee is subject to Sections 9.10 and 9.11 hereof.

<PAGE>   73
                                                                              65

     SECTION 9.04. TRUSTEE'S DISCLAIMER. The Trustee makes no representation as
to the validity or adequacy of this Indenture or the Securities, it shall not be
accountable for the Company's use of the proceeds from any Securities
authenticated and delivered by the Trustee in conformity with the provisions of
this Indenture, and it shall not be responsible for any statement of the Company
in the Indenture or any statement in the Securities other than its
authentication.

     SECTION 9.05. NOTICE OF DEFAULTS. If a Default or Event of Default occurs
and is continuing and if it is actually known to the Trustee, the Trustee shall
mail to Noteholders a notice of the Default or Event of Default within 90 days
after it occurs. Except in the case of a Default or Event of Default in payment
on any Security, the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Noteholders.

     SECTION 9.06. REPORTS BY TRUSTEE TO NOTEHOLDERS. Within 60 days after the
reporting date stated in Section 12.10, the Trustee shall mail to Noteholders a
brief report dated as of such reporting date that complies with TIA ss. 313(a)
if and to the extent required by such ss. 313(a). The Trustee also shall comply
with TIA ss. 313(b)(2). The Trustee shall also transmit by mail all reports as
required by TIA ss. 313(c).

     A copy of each report at the time of its mailing to Noteholders shall be
filed with the SEC and each stock exchange on which the Securities are listed.
The Company shall promptly notify the Trustee when the Securities are listed on
any stock exchange.

     SECTION 9.07. COMPENSATION AND INDEMNITY. The Company shall pay to the
Trustee from time to time such compensation for its services hereunder as shall
be agreed to in writing between the Company and the Trustee. The Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all
reasonable and duly documented disbursements, expenses and advances incurred or
made by it. Such disbursements and expenses may include the reasonable and duly
documented disbursements, compensation and expenses of the Trustee's agents and


<PAGE>   74
                                                                              66

counsel.

     The Company shall indemnify each of the Trustee or any predecessor Trustee
and its officers, directors, employees and all other agents against any and all
loss, damage, claim, expense, including taxes (other than taxes based on the
income of the Trustee) or liability incurred by it except as set forth in the
next paragraph. The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity. The Company shall defend the claim and the Trustee
shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable and duly documented fees, disbursements and
expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

     The Company need not reimburse any expense or indemnify against any loss or
liability incurred by the Trustee through negligence or bad faith.

     To secure the Company's payment obligations in this Section, the Trustee
shall have a lien prior to the Securities on all money or property held or
collected by the Trustee, except money or property held in trust to pay
principal and interest on particular Securities.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 8.01(g) or (h) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

     The provisions of this Section 9.07 shall survive the termination of this
Indenture, as provided by Section 10.01 hereof.

     SECTION 9.08. REPLACEMENT OF TRUSTEE. A resignation or removal of the
Trustee and appointment of a successor Trustee shall become effective only upon
the successor Trustee's acceptance of appointment as provided in this Section.



<PAGE>   75
                                                                              67

     The Trustee may resign by so notifying the Company. The Noteholders of a
majority in principal amount of the then outstanding Securities may remove the
Trustee by so notifying the Trustee and the Company. The Company may remove the
Trustee if:

          (a) the Trustee fails to comply with Section 9.10 hereof, unless the
     Trustee's duty to resign is stayed as provided in TIA ss. 310(b);

          (b) the Trustee is adjudged a bankrupt or an insolvent or an order for
     relief is entered with respect to the Trustee under any Bankruptcy Law;

          (c) a Custodian or public officer takes charge of
     the Trustee or its property; or

          (d) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the
Noteholders of a majority in principal amount of the then outstanding Securities
may appoint a successor Trustee to replace the successor Trustee appointed by
the Company.

     If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Noteholders of at least 10% in principal amount of the then outstanding
Securities may petition any court of competent jurisdiction for the appointment
of a successor Trustee.

     If the Trustee fails to comply with Section 9.10 hereof, unless the
Trustee's duty to resign is stayed as provided in TIA [Section] 310(b), any
Noteholder who has been a bona fide holder of a Security for at least six months
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Thereupon the resignation or removal
of the retiring Trustee shall become effective, the Company shall promptly pay
all amounts due and payable to the retiring Trustee pursuant to Section 9.07
hereof and the successor Trustee shall have all the rights, powers and duties of
the 




<PAGE>   76
                                                                              68

Trustee under this Indenture. The successor Trustee shall mail a notice of its
succession to Noteholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 9.07 hereof. Notwithstanding replacement of the Trustee
pursuant to this Section 9.08, the Company's obligations under Section 9.07
hereof shall continue for the benefit of the retiring trustee with respect to
expenses and liabilities incurred by it prior to such replacement.

     SECTION 9.09. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee
consolidates, merges or converts into, or transfers all or substantially all of
its corporate trust business to, another corporation, the successor corporation
without any further act shall be the successor Trustee.

     SECTION 9.10. ELIGIBILITY; DISQUALIFICATION. This Indenture shall always
have a Trustee who satisfies the requirements of TIA ss. 310(a)(1) and (5). The
Trustee shall always have a combined capital and surplus as stated in Section
12.10 hereof. The Trustee is subject to TIA ss. 310(b).

     SECTION 9.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. The
Trustee is subject to TIA ss. 311(a), excluding any creditor relationship listed
in TIA ss. 311(b). A Trustee who has resigned or been removed shall be subject
to TIA ss. 311(a) to the extent indicated therein.

     SECTION 9.12. SECTIONS APPLICABLE TO REGISTRAR, PAYING AGENT AND CONVERSION
AGENT. The term "Trustee" as used in Sections 9.01, 9.02, 9.03, 9.04 and 9.07
hereof shall (unless the context requires otherwise) be construed as extending
to and including the Trustee acting in its capacity, if any, as Registrar,
Paying Agent and Conversion Agent.

                             Discharge of Indenture
                             ----------------------

     SECTION 10.01. TERMINATION OF COMPANY'S OBLIGATIONS. This Indenture shall
cease to be of further effect (except that the Company's obligations under
Sections 9.07 and 10.02 hereof shall survive) when all outstanding Securities
theretofore authenticated and issued have been delivered to the Trustee for
cancellation and the Company has paid all sums payable hereunder.

     Thereupon, the Trustee upon written request of the Company, shall
acknowledge in writing the discharge of the Company's obligations under this
Indenture, except for those surviving obligations specified above.

     SECTION 10.02. REPAYMENT TO COMPANY. The Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess money or securities held by
them at any time.

     The Trustee and the Paying Agent shall pay to the Company upon written
request any money held by them for the payment of principal, interest or
Additional Amounts, if any, that remains unclaimed for two years after the date
upon which such payment shall have become due; PROVIDED, HOWEVER, that the
Company shall have first caused notice of such payment to the Company to be
mailed to each Noteholder entitled thereto no less than 30 days prior to such
payment. After payment to the Company, the Trustee and the Paying Agent shall
have no further liability with respect to such money and Noteholders entitled to
the money must look to the Company for payment as general creditors unless any
applicable abandoned property law designates another person.

                                   ARTICLE XI

                       Amendments, Supplements and Waivers
                       -----------------------------------

     SECTION 11.01. WITHOUT CONSENT OF NOTEHOLDERS. The Company and the Trustee
may amend or supplement this Indenture or the Securities without the consent of
any Noteholder:

          (a) to cure any ambiguity, defect or inconsistency;



<PAGE>   78
                                                                              70

          (b) to comply with Sections 5.13 and 7.01 hereof;

          (c) to provide for uncertificated Securities in addition to 
     certificated Securities;

          (d) to make any change that does not adversely affect the legal rights
     hereunder of any Noteholder;

          (e) to qualify this Indenture under the TIA or to comply with the
     requirements of the SEC in order to maintain the qualification of the
     Indenture under the TIA; or

          (f) to make any change that provides any additional rights or 
     benefits to the holders of Securities.

     An amendment under this Section may not make any change that adversely
affects the rights under Article VI of any holder of Senior Debt then
outstanding unless the holders of such Senior Debt (or any group or
representative thereof authorized to give a consent) consent to such change.

     SECTION 11.02. WITH CONSENT OF NOTEHOLDERS. Subject to Section 8.07 hereof,
the Company and the Trustee may amend or supplement this Indenture or the
Securities with the written consent (including consents obtained in connection
with any tender offer or exchange offer for Securities) of the Noteholders of at
least a majority in principal amount of the then outstanding Securities. Subject
to Sections 8.04 and 8.07 hereof, the Noteholders of a majority in principal
amount of the Securities then outstanding may also by their written consent
(including consents obtained in connection with any tender offer or exchange
offer for Securities) waive any existing Default or Event of Default as provided
in Section 8.04 or waive compliance in a particular instance by the Company with
any provision of this Indenture or the Securities. However, without the consent
of each Noteholder affected, an amendment, supplement or waiver under this
Section may not (with respect to any Securities held by a nonconsenting
Noteholder):

          (a) reduce the amount of Securities whose Noteholders must consent 
     to an amendment, supplement or waiver;



<PAGE>   79

                                                                              71
          (b) reduce the rate of or change the time for payment of interest on 
     any Security;

          (c) reduce the principal of or change the fixed maturity of any 
     Security or alter the redemption provisions with respect thereto;

          (d) make any Security payable in money other than that stated in the
     Security;

          (e) make any change in Section 8.04, 8.07 or 11.02 hereof (this 
     sentence);

          (f) waive a default in the payment of the Designated Event Payment 
     or the principal of, or interest on, any Security (other than as provided
     in Section 8.04);

          (g) waive a redemption payment payable on any Security;

          (h) impair the right of Noteholders to convert Securities into Common
     Stock of the Company or adversely affect the rights of any Noteholders
     under Section 4.07 or 4.08; or

          (i) modify Articles V or VI hereof in a manner adverse to the 
     Noteholders.

     To secure a consent of the Noteholders under this Section 11.02, it shall
not be necessary for the Noteholders to approve the particular form of any
proposed amendment, supplement or waiver, but it shall be sufficient if such
consent approves the substance thereof.

     An amendment under this Section may not make any change that adversely
affects the rights under Article VI of any holder of Senior Debt then
outstanding unless the holders of such Senior Debt (or any group or
representative thereof authorized to give a consent) consent to such change.

     After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to Noteholders a notice briefly describing the
amendment or waiver.



<PAGE>   80
                                                                              72

     SECTION 11.03. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment to this
Indenture or the Securities shall be set forth in a supplemental indenture that
complies with the TIA as then in effect.

     SECTION 11.04. REVOCATION AND EFFECT OF CONSENTS. Until an amendment,
supplement or waiver becomes effective, a consent to it by a Noteholder of a
Security is a continuing consent by the Noteholder and every subsequent
Noteholder of a Security or portion of a Security that evidences the same debt
as the consenting Noteholder's Security, even if notation of the consent is not
made on any Security. However, any such Noteholder or subsequent Noteholder may
revoke the consent as to such Noteholder's Security or portion of a Security if
the Trustee receives the notice of revocation before the date on which the
Trustee receives an Officers' Certificate certifying that the Noteholders of the
requisite principal amount of Securities have consented to the amendment,
supplement or waiver.

     The Company may, but shall not be obligated to, fix a record date for the
purpose of determining the Noteholders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then notwithstanding the
provisions of the immediately preceding paragraph, those persons who were
Noteholders at such record date (or their duly designated proxies), and only
those persons, shall be entitled to consent to such amendment, supplement or
waiver or to revoke any consent previously given, whether or not such persons
continue to be Noteholders after such record date. No consent shall be valid or
effective for more than 90 days after such record date unless consents from
Noteholders of the principal amount of Securities required hereunder for such
amendment or waiver to be effective shall have also been given and not revoked
within such 90-day period.

     After an amendment, supplement or waiver becomes effective it shall bind
every Noteholder, unless it is of the type described in any of clauses (a)
through (i) of Section 11.02 hereof. In such case, the amendment or waiver shall
bind each Noteholder who has consented to it and every subsequent Noteholder
that evidences the same debt as the consenting Noteholder's Security.

     SECTION 11.05. NOTATION ON OR EXCHANGE OF SECURITIES. The Trustee may place
an appropriate notation 




<PAGE>   81
                                                                              73

about an amendment or waiver on any Security thereafter
authenticated. The Company in exchange for all Securities may issue and the
Trustee shall authenticate new Securities that reflect the amendment or waiver.

     SECTION 11.06. TRUSTEE PROTECTED. The Trustee shall sign all supplemental
indentures, except that the Trustee may, but need not, sign any supplemental
indenture that adversely affects its rights. In executing, or accepting the
additional trusts created by, any supplemental indenture permitted by this
Article or the modification thereby of the trusts created by this Indenture, the
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture.

                                   ARTICLE XII

                                  Miscellaneous
                                  -------------

     SECTION 12.01. TRUST INDENTURE ACT CONTROLS. If any provision of this
Indenture limits, qualifies, or conflicts with another provision which is
automatically deemed to be incorporated in this Indenture by the TIA, the
incorporated provision shall control.

     SECTION 12.02. NOTICES. Any notice or communication by the Company or the
Trustee to the other is duly given if in writing and delivered in person or
mailed by first-class mail to the other's address stated in Section 12.10
hereof. The Company or the Trustee by notice to the other may designate
additional or different addresses for subsequent notices or communications.

     Any notice or communication to a Noteholder shall be mailed by first-class
mail to his address shown on the register kept by the Registrar. Failure to mail
a notice or communication to a Noteholder or any defect in it shall not affect
its sufficiency with respect to other Noteholders.

     If a notice or communication is mailed in the manner provided above within
the time prescribed, it is duly given, whether or not the addressee receives it.

     If the Company mails a notice or communication to Noteholders, it shall
mail a copy to the Trustee and each 


<PAGE>   82
                                                                              74

Agent at the same time.

     All other notices or communications shall be in writing.

     In case by reason of the suspension of regular mail service, or by reason
of any other cause, it shall be impossible to mail any notice as required by the
Indenture, then such method of notification as shall be made with the approval
of the Trustee shall constitute a sufficient mailing of such notice.

     SECTION 12.03. COMMUNICATION BY NOTEHOLDERS WITH OTHER NOTEHOLDERS.
Noteholders may communicate pursuant to TIA ss. 312(b) with other Noteholders
with respect to their rights under this Indenture or the Securities. The
Company, the Trustee, the Registrar and anyone else shall have the protection of
TIA ss. 312(c).

     SECTION 12.04. CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT. Upon any
request or application by the Company to the Trustee to take any action under
this Indenture, the Company shall furnish to the Trustee:

          (a) an Officers' Certificate stating that, in the opinion of the
     signers, all conditions precedent, if any, provided for in this Indenture
     relating to the proposed action have been complied with; and

          (b) an Opinion of Counsel stating that, in the opinion of such
     counsel, all such conditions precedent have been complied with.

     SECTION 12.05. STATEMENTS REQUIRED IN CERTIFICATE OR OPINION. Each
certificate or opinion with respect to compliance with a condition or covenant
provided for in this Indenture (other than pursuant to Section 4.03) shall
include:

          (a) a statement that the person signing such certificate or rendering
     such opinion has read such covenant or condition;

          (b) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinions contained in such
     certificate or opinion are based;



<PAGE>   83
                                                                              75

          (c) a statement that, in the opinion of such person, such person has
     made such examination or investigation as is necessary to enable such
     person to express an informed opinion as to whether or not such covenant or
     condition has been complied with; and

          (d) a statement as to whether or not, in the opinion of such person,
     such condition or covenant has been complied with.

     SECTION 12.06. RULES BY TRUSTEE AND AGENTS. The Trustee may make reasonable
rules for action by, or a meeting of, Noteholders. The Registrar or Paying Agent
may make reasonable rules and set reasonable requirements for its functions.

     SECTION 12.07. LEGAL HOLIDAYS. A "Legal Holiday" is a Saturday, a Sunday or
a day on which banking institutions in the State of New York are not required to
be open. If a payment date is a Legal Holiday at a place of payment, payment may
be made at that place on the next succeeding day that is not a Legal Holiday,
and no interest shall accrue for the intervening period. If any other operative
date for purposes of this Indenture shall occur on a Legal Holiday then for all
purposes the next succeeding day that is not a Legal Holiday shall be such
operative date.

     SECTION 12.08. NO RECOURSE AGAINST OTHERS. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. Each Noteholder by accepting a Security waives and releases all such
liability. The waiver and release are part of the consideration for the issue of
the Securities.

     SECTION 12.09. COUNTERPARTS. This Indenture may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

     SECTION 12.10. VARIABLE PROVISIONS. "Officer" means the Chairman of the
Board, the President, any Vice-President, the Treasurer, the Secretary, any
Assistant Treasurer or any Assistant Secretary of the Company.

     The Company initially appoints the Trustee as Paying Agent, Registrar,
Conversion Agent and authenticating agent and the Trustee hereby accepts such
appointments.

     The first certificate pursuant to Section 4.03 hereof shall be for the
fiscal year ending on December 31, 1996.

     The reporting date for Section 9.06 hereof is April 15 of each year. The

                  5 1/2% Convertible Subordinated Note Due 2006

     1. INTEREST. MOLTEN METAL TECHNOLOGY, INC., a Delaware corporation (the
"Company"), is the issuer of this 5 1/2% Convertible Subordinated Note Due 2006
(the "Convertible Note"). The Company promises to pay interest on the
Convertible Notes at the rate per annum shown above subject to Section 11
hereof, in cash semiannually on each May 1 and November 1, commencing on
November 1, 1996, to holders of record on the immediately preceding April 15 and
October 15.

     Interest on the Convertible Notes will accrue from the most recent date to
which interest has been paid, or if no interest has been paid, from May 1, 1996.
Interest will be computed on the basis of a 360-day year of 12 30-day months. To
the extent lawful, the Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue installments of
interest (without regard to any applicable grace period) at the rate borne by
the Convertible Notes, compounded semi- annually.

     2. METHOD OF PAYMENT. The Company will pay interest on the Convertible
Notes (except defaulted interest) to the persons who are registered holders of
the Convertible Notes at the close of business on the record date for the next
interest payment date even though Convertible Notes are cancelled after the
record date and on or before the interest payment date. The Noteholder hereof
must surrender Convertible Notes to a Paying Agent to collect principal
payments. The Company will pay principal and interest in money of the United
States that at the time of payment is legal tender for payment of public and
private debts. The Company may pay principal by check payable in such money or
by wire transfer to an account maintained by the holder with a bank in New York
City (if the holder of the Convertible

                                                                               8

Notes holds an aggregate principal amount of Convertible Notes in excess of
$5,000,000). The Company may pay interest by mailing an interest check to a
holder's registered address or, upon application by the holder hereof to the
Registrar, not later than the applicable record date, by wire transfer to an
account maintained by the holder with a bank in New York City (if the holder of
the Convertible Notes holds an aggregate principal amount of Convertible Notes
in excess of $5,000,000).

     3. PAYING AGENT AND REGISTRAR. The Trustee will act as Paying Agent,
Registrar and Conversion Agent. The Company may change any Paying Agent,
Registrar, co-registrar or Conversion Agent without prior notice. The Company or
any of its Affiliates may act in any such capacity.

     4. INDENTURE. The Company issued the Convertible Notes under an indenture,
dated as of May 1, 1996 (the "Indenture"), between the Company and The Bank of
New York, as Trustee. The terms of the Convertible Notes include those stated in
the Indenture and those made part of the Indenture by the Trust Indenture Act of
1939 (15 U.S. Code ss.ss. 77aaa-77bbbb) as in effect on the date of the
Indenture. The Convertible Notes are subject to, and qualified by, all such
terms, certain of which are summarized hereon, and Noteholders are referred to
the Indenture and such Act for a statement of such terms. The Convertible Notes
are unsecured obligations of the Company limited to (except as otherwise
provided in the Indenture) up to an aggregate principal amount of $125,000,000
(plus up to $18,750,000 aggregate principal amount of Convertible Notes that may
be sold by the Company pursuant to the over-allotment option granted pursuant to
the Purchase Agreement), and are subordinated in right of payment to all
existing and future Senior Debt of the Company as provided in the Indenture. Any
holder of this Convertible Note shall be deemed to have agreed to and be bound
by all the terms and conditions contained in the Indenture applicable to a
holder of a Convertible Note.

<TABLE>
     5. OPTIONAL REDEMPTION. The Convertible Notes are not subject to redemption
at the Company's option prior to May 1, 1999. On such date and thereafter, the
Convertible Notes will be subject to redemption at the option of the Company, in
whole or in part (in any integral multiple of $5,000), upon not less than 30 nor
more than 60 days prior notice by mail at the following redemption prices
(expressed as percentages of the principal amount set forth below), if redeemed
during the 12-month period beginning May 1 of the years indicated:

and, at May 1, 2005 and thereafter, 100%, in each case together with accrued
interest up to but not including the redemption date (subject to the right of
holders of record on the relevant record date to receive interest due on an
interest payment date). On or after the redemption date, interest will cease to
accrue on the Convertible Notes, or portion thereof, called for redemption.

     If as a result of a Tax Law Change, the Company has or will become
obligated to pay to the Holder of this Convertible Note, Additional Amounts, and
such obligation cannot be avoided by the Company taking reasonable measures
available to it, then the Company may, at its option, redeem this Convertible
Note as a whole, but not in part, upon not less than 30 nor more than 60 days'
notice to the holder of this Convertible Note prior to the redemption date, at a
redemption price equal to 100% of the principal amount plus interest accrued to
the redemption date, and any Additional Amounts then payable; PROVIDED, HOWEVER,
that no such notice of redemption shall be given earlier than 90 days prior to
the earliest date on which the Company would be obligated to pay any such
Additional Amounts were a payment in respect of the Convertible Notes then due.
Prior to the giving of any notice of redemption pursuant to this paragraph, the
Company shall deliver to the Trustee (a) an Officers' Certificate stating that
the Company is entitled to effect such redemption and setting forth a statement
of facts showing that the conditions precedent to the right of the Company so to
redeem have occurred and (b) an opinion of independent counsel of recognized
standing selected by the Company to the effect that the Company has or will
become obligated to pay such Additional Amounts as a result of such Tax Law
Change. The Company's right to redeem this Convertible Note shall continue as
long as the Company is obligated to pay such Additional Amounts, notwithstanding
that the Company shall have made payments of such Additional Amounts.

     6. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30
days but not more than 60 days before the redemption date to each holder of the
Convertible Notes to be redeemed at his address of record. The Convertible Notes
in denominations larger than $5,000 may be redeemed in part but only in integral
multiples of $5,000. 





<PAGE>   96
                                                                              10

In the event of a redemption of less than all of the Convertible Notes, the
Convertible Notes will be chosen for redemption by the Trustee in accordance
with the Indenture. Unless the Company defaults in making such redemption
payment, or the Paying Agent is prohibited from making such payment pursuant to
the Indenture, interest ceases to accrue on the Convertible Notes or portions of
them called for redemption on and after the redemption date.

     If this Convertible Note is redeemed subsequent to a record date with
respect to any interest payment date specified above and on or prior to such
interest payment date, then any accrued interest will be paid to the person in
whose name this Convertible Note is registered at the close of business on such
record date.

     7. MANDATORY REDEMPTION. The Company will not be required to make mandatory
redemption payments with respect to the Convertible Notes. There are no sinking
fund payments with respect to the Convertible Notes.

     8. REPURCHASE AT OPTION OF HOLDER. If there is a Designated Event, the
Company shall be required to offer to purchase on the Designated Event Payment
Date all outstanding Convertible Notes at a purchase price equal to 100% of the
principal amount thereof on the date of purchase, plus accrued and unpaid
interest to the Designated Event Payment Date. Holders of Convertible Notes that
are subject to an offer to purchase will receive a Designated Event Offer from
the Company prior to any related Designated Event Payment Date and may elect to
have such Convertible Notes or portions thereof in authorized denominations
purchased by completing the form entitled "Option of Noteholder To Elect
Purchase" appearing below.

     9. SUBORDINATION. The payment of the principal of, interest on or any other
amounts due on the Convertible Notes is subordinated in right of payment to all
existing and future Senior Debt of the Company, as described in the Indenture.
Each Noteholder, by accepting a Convertible Note, agrees to such subordination
and authorizes and directs the Trustee on its behalf to take such action as may
be necessary or appropriate to effectuate the subordination so provided and
appoints the Trustee as its attorney-in-fact for such purpose.

     10. CONVERSION. The holder of any Convertible Note has the right,
exercisable at any time after 90 days 




<PAGE>   97
                                                                              11

following the date of original issuance thereof and prior to the close of
business (New York time) on the date of the Convertible Note's maturity, to
convert the principal amount thereof (or any portion thereof that is an integral
multiple of $5,000) into shares of Common Stock at the initial Conversion Price
of $38.75 per share, subject to adjustment under certain circumstances, except
(i) that if a Convertible Note is called for redemption, the conversion right
will terminate at the close of business on the Business Day immediately
preceding the date fixed for redemption and (ii) if a Convertible Note is
submitted for repurchase in connection with a Designated Event, the conversion
right will terminate with respect to the portion submitted for repurchase upon
such submission.

     To convert a Convertible Note, a holder must (1) complete and sign a notice
of election to convert substantially in the form set forth below, (2) surrender
the Convertible Note to a Conversion Agent, (3) furnish appropriate endorsements
or transfer documents if required by the Registrar or Conversion Agent and (4)
pay any transfer or similar tax, if required. Upon conversion, no adjustment or
payment will be made for interest or dividends, but if any Noteholder surrenders
a Convertible Note for conversion after the close of business on the record date
for the payment of an installment of interest and prior to the opening of
business on the next interest payment date, then, notwithstanding such
conversion, the interest payable on such interest payment date will be paid to
the registered holder of such Convertible Note on such record date. In such
event, such Convertible Note, when surrendered for conversion, must be
accompanied by payment in funds acceptable to the Company of an amount equal to
the interest payable on such interest payment date on the portion so converted.
The number of shares of Common Stock issuable upon conversion of a Convertible
Note is determined by dividing the principal amount of the Convertible Note
converted by the Conversion Price in effect on the Conversion Date. No
fractional shares will be issued upon conversion but a cash adjustment will be

     11. REGISTRATION RIGHTS. The holder of this Convertible Note (other than a
holder who purchased this Convertible Note in reliance on Regulation S under the
Securities Act) is entitled to the benefits of a Registration Agreement, dated
April 25, 1996, between the Company and the Initial Purchasers (the
"Registration

                                                                              12

Agreement"). Pursuant to the Registration Agreement the Company
has agreed for the benefit of the holders of the Convertible Notes, that (i) it
will, at its cost, within 120 days after the closing of the sale of the
Convertible Notes (the "Closing"), file a shelf registration statement (the
"Shelf Registration Statement") with the Securities and Exchange Commission (the
"Commission") with respect to resales of the Convertible Notes and the Common
Stock issuable upon conversion thereof, (ii) within 180 days after the Closing,
such Shelf Registration Statement shall be declared effective by the Commission
and (iii) the Company will maintain such Shelf Registration Statement
continuously effective under the Securities Act until the third anniversary of
the date of the Closing (or, in the event that Rule 144(k) under the Securities
Act is amended to provide for a shorter holding period, until the end of such
shorter holding period) or such earlier date as of which all the Convertible
Notes or the Common Stock issuable upon conversion thereof have been sold
pursuant to such Shelf Registration Statement. If the Company fails to comply
with clause (i) above then, at such time, the per annum interest rate on the
Convertible Notes will increase by 25 basis points. Such increase will remain in
effect until the date on which such Shelf Registration Statement is filed, on
which date the interest rate on the Convertible Notes will revert to the
interest rate originally borne by the Convertible Notes plus any increase in
such interest rate pursuant to the following sentence. If the Shelf Registration
Statement is not declared effective as provided in clause (ii) above, then, at
such time and on each date that would have been the successive 30th day
following such time, the per annum interest rate on the Convertible Notes (which
interest rate will be the original interest rate on the Convertible Notes plus
any increase or increases in such interest rate pursuant to the preceding
sentence and this sentence) will increase by an additional 25 basis points;
PROVIDED that the interest rate will not increase by more than 50 basis points
pursuant to this sentence and will not increase by more than 75 basis points
pursuant to this sentence and the preceding sentence. Such increase or increases
will remain in effect until the date on which such Shelf Registration Statement
is declared effective, on which date the interest rate on the Convertible Notes
will revert to the interest rate originally borne by the Convertible Notes.
Pursuant to clause (iii) above, however, if the Company fails to keep the Shelf
Registration Statement continuously effective for the period specified above,
then at such time as the Shelf Registration Statement is no

                                                                              13

longer effective and on each date thereafter that is the successive 30th day
subsequent to such time and until the earlier of (i) the date that the Shelf
Registration Statement is again deemed effective or (ii) the date that is the
third anniversary of the Closing (or, in the event that Rule 144(k) under the
Securities Act is amended to provide for a shorter holding period, until the end
of such shorter holding period) or (iii) the date as of which all of the
Convertible Notes and/or the Common Stock issuable upon conversion thereof are
sold pursuant to the Shelf Registration Statement, the per annum interest rate
on the Convertible Notes will increase by an additional 25 basis points;
PROVIDED, HOWEVER, that the interest rate will not increase by more than 50
basis points pursuant to this sentence.

     Pursuant to the Registration Agreement, the Company may suspend the use of
the prospectus which is a part of the Shelf Registration Statement for a period
not to exceed 30 days in any three month period or four periods not to exceed an
aggregate of 60 days in any twelve month period under certain circumstances. The
holders of Convertible Notes will not be entitled to additional interest as set
forth in the preceding paragraph solely because of such suspension.

     12. DENOMINATIONS, TRANSFER, EXCHANGE. The Convertible Notes are in
registered form, without coupons, in denominations of $5,000 and integral
multiples of $5,000. The transfer of Convertible Notes may be registered, and
Convertible Notes may be exchanged, as provided in the Indenture. The Registrar
may require a Noteholder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture. The Registrar need not exchange or register
the transfer of any Convertible Note or portion of a Convertible Note selected
for redemption (except the unredeemed portion of any Convertible Note being
redeemed in part). Also, it need not exchange or register the transfer of any
Convertible Note for a period of 15 days before a selection of Convertible Notes
to be redeemed.

     13. PERSONS DEEMED OWNERS. Except as provided in paragraph 2 of this
Convertible Note, the registered Noteholder of a Convertible Note may be treated
as its owner for all purposes.

     14. UNCLAIMED MONEY. If money for the payment of 




<PAGE>   100
                                                                              14

principal or interest remains unclaimed for two years, the Trustee and the
Paying Agent shall pay the money back to the Company at its written request.
After that, Noteholders of Convertible Notes entitled to the money must look to
the Company for payment unless an abandoned property law designates another
person and all liability of the Trustee and such Paying Agent with respect to
such money shall cease.

     15. DEFAULTS AND REMEDIES. The Convertible Notes shall have the Events of
Default as set forth in Section 8.01 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the Noteholders of at least 25% in
aggregate principal amount of the then outstanding Convertible Notes by notice
to the Company and the Trustee may declare all the Convertible Notes to be due
and payable immediately, except that in the case of an Event of Default arising
from certain events of bankruptcy or insolvency, all unpaid principal and
interest accrued on the Convertible Notes shall become due and payable
immediately without further action or notice. Upon acceleration as described in
either of the preceding sentences, the subordination provisions of the Indenture
preclude any payment being made to Noteholders for at least 5 days except as
otherwise provided in the Indenture.

     The Noteholders of a majority in principal amount of the Convertible Notes
then outstanding by written notice to the Trustee may rescind an acceleration
and its consequences if all existing Events of Default have been cured or waived
except nonpayment of principal or interest that has become due solely because of
the acceleration. Noteholders may not enforce the Indenture or the Convertible
Notes except as provided in the Indenture. Subject to certain limitations,
Noteholders of a majority in principal amount of the then outstanding
Convertible Notes issued under the Indenture may direct the Trustee in its
exercise of any trust or power. The Company must furnish compliance certificates
to the Trustee annually. The above description of Events of Default and remedies
is qualified by reference to, and subject in its entirety by, the more complete
description thereof contained in the Indenture.

     16. AMENDMENTS, SUPPLEMENTS AND WAIVERS. Subject to certain exceptions, the
Indenture or the Convertible Notes may be amended or supplemented with the
consent of the Noteholders of at least a majority in principal amount of 




<PAGE>   101
                                                                              15

the then outstanding Convertible Notes (including consents obtained in
connection with a tender offer or exchange offer for Convertible Notes), and any
existing default may be waived with the consent of the Noteholders of a majority
in principal amount of the then outstanding Convertible Notes including consents
obtained in connection with a tender offer or exchange offer for Convertible
Notes. Without the consent of any Noteholder, the Indenture or the Convertible
Notes may be amended, among other things, to cure any ambiguity, defect or
inconsistency, to provide for assumption of the Company's obligations to
Noteholders, to make any change that does not adversely affect the rights of any
Noteholder, to qualify the Indenture under the TIA, and to comply with the
requirements of the SEC in order to maintain the qualification of the Indenture
under the TIA.

     17. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual or
any other capacity, may become the owner or pledgee of Convertible Notes and may
otherwise deal with the Company or an Affiliate with the same rights it would
have if it were not Trustee, subject to certain limitations provided for in the
Indenture and in the TIA. Any Agent may do the same with like rights.

     18. NO RECOURSE AGAINST OTHERS. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Convertible Notes or the Indenture or for
any claim based on, in respect of or by reason of such obligations or their
creation. Each Noteholder, by accepting a Convertible Note, waives and releases
all such liability. The waiver and release are part of the consideration for the
issue of the Convertible Notes.

     19. GOVERNING LAW. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN
THE INDENTURE AND THE CONVERTIBLE NOTES WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.

     20. AUTHENTICATION. The Convertible Notes shall not be valid until
authenticated by the manual signature of an authorized signatory of the Trustee
or an authenticating agent.

     21. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Noteholder or an assignee, such as: TEN COM (for tenants in common), TEN ENT
(for tenants by the entireties), JT TEN (for joint tenants with right of

Molten Metal Technology, Inc., a Delaware company (the "Company"), we confirm
that:

     1. We understand that the Securities and the Common Stock issuable upon
conversion thereof have not been registered under the Securities Act of 1933, as
amended (the "Securities Act"), and may not be sold except as permitted in the
following sentence. We understand and agree, on our own behalf and on behalf of
any accounts for which we are acting as hereinafter stated, (x) that such
Securities are being offered only in a transaction not involving any public
offering within the meaning of the Securities Act, (y) that if we should resell,
pledge or otherwise transfer such Securities and the Common Stock issuable upon
conversion thereof within three years after the date of the original issuance of
the Securities or within three months after we cease to be an affiliate (within
the meaning of Rule 144 under the Securities Act) of the Company, such
Securities and the Common Stock issuable upon conversion thereof may be resold,
pledged or transferred only (i) to the Company, (ii) so long as Securities and
the Common Stock issuable upon conversion thereof are eligible for resale
pursuant to Rule 144A under the Securities Act ("Rule 144A"), to a person whom
we reasonably believe is a "qualified institutional buyer" (as indicated by the

accordance with Regulation S under the Securities Act (as indicated by the box
checked by the transferor on the Certificate of Transfer on the reverse of the

under the Securities Act provided by Rule 144 (if applicable) under the
Securities Act, or (v) pursuant to an effective registration statement under the
Securities Act, in each case in accordance with any applicable securities laws
of any state of the United States, and we will notify any purchaser of the
Securities or the Common Stock issuable upon conversion thereof from us of the
above resale restriction, if then applicable. We further understand that, in
connection with any transfer of the Securities or the Common Stock issuable upon
conversion thereof by us, the Company and the Trustee (or, in the case of Common
Stock, the Transfer Agent) may request, and if so requested we will furnish,
such certificates, legal opinions and other information as they may reasonably
require to confirm that any such transfer complies with the foregoing
restrictions.

     2. With respect to the transactions contemplated by the Offering
Memorandum, we have such

knowledge and experience in financial and business matters as to be capable of
evaluating the merits and risks of our investment in the Securities, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or its investment and can afford the complete loss of such investment.

     3. We understand that the minimum principal amount of Securities that may
be purchased by an institutional accredited investor is $250,000.

     4. We understand that the Company and the Initial Purchasers, and others
will rely upon the truth and accuracy of the foregoing acknowledgments,
representations and agreements and we agree that if any of the acknowledgements,
representations and warranties deemed to have been made by us by our purchase of
Securities, for our own account or for one or more accounts as to each of which
we exercise sole investment discretion, are no longer accurate, we shall
promptly notify the Company and the Initial Purchasers.

     5. We are acquiring the Securities purchased by us for investment purposes,
and not for distribution, for our own account or for one or more accounts as to
each of which we exercise sole investment discretion and we are or such account
