PART I

ITEM 1. BUSINESS

TECHNOLOGY OVERVIEW

      Molten Metal Technology, Inc. (including its wholly-owned subsidiaries,
"MMT" or the "Company") is an environmental technology company engaged in the
commercialization and continued development of its innovative, proprietary
processing technology known as Catalytic Extraction Processing ("CEP"). The core
of CEP is a molten metal bath operating at approximately 3,000(degree)F into
which feedstocks and selected chemicals ("reactants") can be introduced. The
catalytic and solvent effect of the molten metal bath causes feedstocks to break
down into their constituent elements and dissolve into the molten metal. The
addition of various selected chemicals to the molten metal allows feedstocks to
reform and be recovered as different materials ("Elemental Recycling(TM)") which
generally can be re-used as a raw material by the feedstock generator or can be
sold to other users. The CEP system largely consists of process, instrument and
control components currently used widely in the metallurgical and chemical
industries.

      MMT believes that a wide variety of chemical intermediates, by-products
and wastes, both organic and inorganic, can be processed by CEP. Liquids, gases
or solids can be introduced into the CEP system through either bottom or top
addition. Within the CEP system, the elemental constituents of the feedstock and
reactants separate and can be recovered from three distinct phases: (i) gases
which rise above the molten metal bath; (ii) molten ceramic products which form
a separate layer on top of the liquid metal; and (iii) metallic elements which
dissolve and collect in the liquid metal bath.

      Recovered products can be re-used as raw materials in the production
process or sold to other industrial customers. For example, it is expected that
many gaseous components can be used as fuels or chemical feedstocks; many
ceramic materials can be recovered and used as specialty chemicals, ceramic
substitutes or abrasives; and most metallic components can be removed and
granulated or cast as ingots for sale.

      The Company currently is developing various applications for its CEP(1)
technology to process particular classes of hazardous wastes and industrial
by-products. Each application uses a molten metal bath to separate waste
compounds into their elemental constituents and reconfigure the elements into
potential gaseous, ceramic, and metal products. MMT has developed
Quantum-CEP(TM) (or Q-CEP(TM)) to process radioactive wastes and "mixed wastes"
(containing both radioactive and hazardous constituents). Quantum-CEP breaks
down hazardous and toxic materials, while separating and containing radioactive
elements in a stable, self-shielding form suitable for storage or final
disposal. This can result in a substantial reduction in the volume of
radioactive materials requiring storage or disposal. In addition, certain of the
resulting non-radioactive materials have the potential to be recycled into
products or re-used in Q-CEP plant operations. Through acquisition and internal
development, the Company also is developing additional technologies that can be
used to process various types of wastes. These technologies include the methods
and equipment for handling and processing radioactive liquids and resins that
the Company acquired in December 1996 and January 1997 from Scientific Ecology
Group, Inc. and VECTRA Technologies, Inc.

MARKET OVERVIEW

      Currently, the most common methods of treatment and disposal of hazardous
and non-hazardous wastes and industrial by-products include landfilling,
deep-well injection, incineration, plasma, vitrification and other thermal
treatment methods, on-site containment (including industrial lagoons) and
release into the environment. Most of these methods have transportation,
treatment and

     technology and its various related applications.


<PAGE>   3


safety risks. In addition, certain of these treatment and disposal methods
result in production of residual waste that may require further treatment prior
to disposal. As a result, many of these methods are being met with increasing
public resistance and more stringent regulations, which may lead to an increased
cost of compliance.

      MMT believes the primary factors that create demand for CEP (other than
Q-CEP) include the need for prospective customers to comply with environmental
regulations in a cost-effective manner and the ability of CEP to process
hazardous and non-hazardous wastes and industrial by-products and generally to
recover products for re-use or sale. With respect to Quantum-CEP, MMT believes
that the primary factors that create demand include customers' regulatory
compliance concerns and the ability of Quantum-CEP to reduce the volume of
radioactive materials. Also in the case of mixed wastes, MMT believes that the
recovery of materials which can potentially be re-used or recycled creates
demand for Q-CEP in this market. In addition, compared to conventional treatment
methods, MMT believes that CEP can be utilized in a manner which minimizes or
eliminates the creation of residual waste, thereby reducing the costs and risks
associated with residual waste disposal.

MMT Target Markets

      For the initial commercialization of CEP, MMT has identified three markets
where it believes CEP offers the greatest immediate value and meets pressing
customer needs: (i) commercial low-level radioactive waste and mixed waste; (ii)
U.S. government waste; and (iii) industrial hazardous waste. In each of these
markets, MMT or M4 Environmental L.P. (the Company's joint venture with Lockheed
Martin Corporation) ("M4")) has constructed or is constructing "first-of-a-kind"
commercial CEP systems.

      In the commercial low-level radioactive waste sector, MMT estimates that
over three million cubic feet (approximately 150 million pounds) of waste is
generated annually in the United States by more than 1,300 generators, including
nuclear power plants and medical and research facilities. These generators seek
technological solutions to effectively process their waste into a weight- and
volume-reduced, stable, self-shielding form, suitable for long-term storage or
disposal. This volume reduction reduces these generators' disposal costs and
lengthens the useful life of current and future radioactive waste repositories.
The Company expects that international markets also will provide additional
opportunities for radioactive waste management. The commercial mixed waste
market in the United States is characterized by a broad range of small volume
waste streams that vary widely in composition. Most of these wastes are
generated from the operations of nuclear power plants. MMT estimates that these
nuclear utilities have stored in excess of 700,000 pounds of mixed waste, and
generate an additional 200,000 to 300,000 pounds of mixed waste annually.

      In the government market, MMT estimates that the United States Department
of Energy ("DOE") and the Department of Defense ("DoD") together spend nearly $8
billion annually on waste management and cleanup programs, making the U.S.
government the world's largest consumer of environmental goods and services.
Wastes requiring treatment at over 30 DOE sites include mixed wastes, waste from
the demilitarization of nuclear weapons, and wastes generated during the
remediation of large-scale decontamination and decommissioning projects. The
major focus of the DoD environmental restoration effort is on munitions
demilitarization, destruction of chemical weapons, and remediation of sites
contaminated with these priority wastes. Another government entity, the United
States Enrichment Corporation ("USEC"), annually produces approximately 15
million kilograms of depleted uranium hexafluoride ("DUF(6)"), a by-product
generated through the conversion of uranium isotopes into highly enriched
uranium. In addition, the DOE currently has approximately 500 million kilograms
of DUF(6) in storage.

      The industrial waste sector includes hazardous wastes as well as
non-hazardous wastes and byproducts. Based on data obtained from the United
States Environmental Protection Agency ("EPA"), MMT estimates that over 250
million tons of waste generated annually in the United States are classified as
hazardous or toxic under the Resource Conservation and Recovery Act of 1976, as
amended ("RCRA"), or the Toxic Substance Control Act ("TSCA"). Target markets
for CEP include wastes from the chemical


                                       2
<PAGE>   4


and petrochemical industries, the metal processing and mining industries, wastes
currently processed by hazardous and municipal waste incinerators and
post-consumer plastics.

COMMERCIALIZATION AND SALES STRATEGY

      In order to accelerate the commercialization of CEP, MMT intends to own
and operate, by itself or through joint ventures, its initial commercial CEP
facilities. Over the longer term, MMT intends to sell plants directly to
customers, which they would operate. In addition to selling plants, the Company
intends to license its technology under arrangements which provide for any or
all of the following: (i) market rights license fees; (ii) technology transfer
fees; (iii) ongoing tolling and license fees based upon the volume of feedstocks
processed or the sale of recovered products; (iv) service fees for project
development, design, engineering, and construction management; and (v) supply of
critical or proprietary CEP components.

      The Company's strategy is to address the demand for a cost-effective
method of processing waste materials while maintaining environmental standards.
Although the CEP systems installed or being installed at each of the Company's
first two commercial facilities and at the M4 Technology Center in Oak Ridge,
Tennessee are central sites to which wastes and feedstocks are shipped for
processing, it is the Company's intent to install CEP systems on-site at
customers' industrial facilities in order to (i) integrate systems on-site to
enable existing facilities to comply with recycling exemptions applicable to
materials that are reclaimed and returned to the manufacturing process that
generated such materials ("closed-loop recycling") and (ii) reduce certain costs
and potential liabilities associated with existing treatment methods, including
transportation and off-site disposal. The Company's business strategy includes
maintaining collaborative arrangements with industry leaders to aid in the
technical development, sales, marketing, design and engineering of CEP systems.
In addition, the Company's commercialization and sales strategy includes
identifying industrial market leaders as initial customer prospects and
performing Technical Development Programs ("TDPs") to demonstrate CEP's
commercial applicability to a variety of customers and waste streams. Such
activities are intended to keep the technical development of CEP focused on
market opportunities.

      The Company believes that its commercialization and sales strategy must be
flexible to adapt to a number of factors that may change over time as the market
for CEP systems and any competing technologies evolve. These factors include,
but are not limited to, the relative attractiveness of target markets based on
the customer demand for CEP systems within each of the Company's target markets
as compared to applicable competing methods of recycling, treatment or disposal;
any changes in environmental regulations and their effect on the Company's
operations and various target markets; and the ability of the Company to
successfully permit and build CEP systems on a timely basis within its target
markets. Accordingly, the Company anticipates that its commercialization and
sales strategy may change over time.

COMMERCIAL DEVELOPMENTS

      Since 1995, the Company has made substantial progress toward constructing
and initiating commercial operations at CEP plants in its three primary
markets. As described below, (i) the Company is processing radioactive ion
exchange resins at its Quantum-CEP facility in Oak Ridge, Tennessee; (ii) MMT,
either directly or through M4, has built and tested commercial, pilot or
bench-scale CEP systems for processing a broad range of wastes, including DUF6,
chemical weapons, radioactive wastes, hazardous wastes, and mixed wastes for
the DOE, DoD, USEC and commercial customers; and (iii) in the industrial
hazardous waste market, the Company is constructing a commercial-scale system
to process chlorinated organic wastes and other hazardous wastes at a Hoechst
Celanese Corporation chemical plant in Bay City, Texas, and the Company is
constructing a demonstration-scale facility to process fly ash produced by
Japanese municipal solid waste incinerators.


                                       3
<PAGE>   5


      The Company also has entered into letters of intent relating to the
development of additional CEP systems for commercial use both in the Company's
three primary markets and in other market segments. During 1997, the Company
will continue operating and developing the CEP systems described below and will
seek to enter into new agreements to develop additional CEP systems. However,
there can be no assurance as to the successful and timely development of these
CEP systems or the successful negotiation of definitive agreements based on the
existing letters of intent. The Company expects that any sales of such CEP
systems will be made after the Company has demonstrated the successful operation
of its other commercial facilities.

Commercial Radioactive Waste Market

      MMT's Q-CEP facility in Oak Ridge, Tennessee began processing radioactive
ion exchange resins in December 1996, and began commercial operations in January
1997. This facility is designed to process up to 130,000 cubic feet per year of
radioactive ion exchange resins from nuclear power plants. Prior to December
1996, the facility was jointly owned and financed by MMT and Scientific Ecology
Group, Inc. ("SEG"), previously a wholly-owned subsidiary of Westinghouse
Electric Corporation ("Westinghouse"). SEG has since been acquired by GTS
Duratek, Inc. In December 1996, MMT of Tennessee Inc., a wholly-owned subsidiary
of the Company ("MMT Tennessee"), purchased SEG's interest in the Q-CEP facility
as well as certain assets used for handling and processing radioactive liquids
and resins ("wet waste") for $31 million in cash. These assets include
contracts, equipment, services and personnel for processing radioactive wastes
at the Q-CEP facility. In connection with that transaction, the agreements that
had been signed by MMT, SEG and Westinghouse in 1994 were terminated. SEG and
GTS Duratek, Inc. continue to be obligated under noncompetition covenants which
generally provide that during the five year period ending December 2001, they
will not compete with MMT in the processing of ion exchange resins in North
America, subject to certain exceptions.

      In January 1997, MMT Tennessee acquired from VECTRA Technologies, Inc.
("VECTRA") certain contracts, equipment and personnel used for handling and
processing radioactive wet waste for $3.9 million in cash. MMT Tennessee will
continue to own and operate the Q-CEP facility and the Company's radioactive
waste services business. These services consist of managing and handling
radioactive wet waste on-site at nuclear power plants, providing equipment such
as casks for transportation and storage of radioactive waste, and processing the
waste using Q-CEP or other processing methods such as reverse osmosis,
demineralization and solidification.

      The acquisitions of SEG's and VECTRA's wet waste business have allowed MMT
Tennessee to significantly expand its radioactive waste processing services. In
conjunction with the Q-CEP facility, MMT Tennessee's wet waste business is able
to offer processing for a wide variety of radioactive liquids and resins
produced by U.S. nuclear power plants. As of March 31, 1997, MMT Tennessee had
contracts or purchase orders in place to provide radioactive processing services
to 18 nuclear utilities, including eight contracts to process radioactive ion
exchange resins.

U.S. Government Market

      PARTNERSHIP WITH LOCKHEED MARTIN CORPORATION. In August 1994, the Company
entered into a series of related agreements with Martin Marietta Corporation to
form M4 Environmental L.P. ("M4"). Martin Marietta has since merged into
Lockheed Martin Corporation ("LMC"), with LMC as the surviving entity. Pursuant
to these agreements, the Company and LMC formed M4, a Delaware limited
partnership, to commercialize CEP to service the environmental remediation,
waste management, decontamination and decommissioning needs of the DoD, the DOE,
and USEC. In April 1996, MMT and LMC expanded M4 through the acquisition by M4
of the Retech division of Lockheed Environmental Systems & Technologies Co., a
wholly-owned subsidiary of LMC. The Retech division designs and manufactures
metallurgical equipment and waste processing systems that utilize a plasma
technology. The Company and LMC, through wholly-owned subsidiaries, each holds a
49.5% limited partnership interest in M4, and a 50% interest in the corporate
general partner of M4, which holds a 1% interest in M4. In March 1997, MMT and
LMC entered into a letter of intent to restructure MMT's and LMC's


                                       4
<PAGE>   6


relationship with respect to M4's market. This restructuring is described below.
During 1996, revenue from M4 accounted for approximately 87% of the Company's
total revenue. This revenue was generated as the result of sales of goods and
services to M4, as well as technology transfer and success fees. As a result of
the restructuring described below, M4 would become a wholly-owned subsidiary of
MMT and its revenues would be consolidated with MMT's. Accordingly, MMT's
revenues from M4 in 1997 primarily will be generated through M4's operations,
including the provision of processing services and funded research and
development for third parties, rather than from M4 purchasing goods and services
from MMT. The Company does not anticipate that these M4 operations will account
for a substantial portion of its revenue for 1997.

            M4 Technology Center. In February 1995, M4 began construction of its
Technology Center in Oak Ridge, Tennessee (the "M4 Technology Center"). In
October 1995, M4 began operating its first CEP system, a demonstration facility
for DUF(6), at the M4 Technology Center. In December 1995, M4 began operating 
its first commercial mixed waste CEP facility. The Company expects the second 
mixed waste system, which is substantially larger than the first system, to 
begin commercial operations during the second half of 1997.

            Hanford Tanked Waste Cleanup. In September 1996, the Company
announced that the DOE had awarded a contract to a technical team led by LMC to
employ technologies including Q-CEP for Phase 1A of the contract for the cleanup
of the tanked waste site in Hanford, Washington. The Hanford site contains
approximately 56 million gallons of highly radioactive waste stored in 177
tanks. The DOE awarded two prime contracts for Phase 1A of the cleanup. The LMC
team includes Numatec, Fluor Daniel, Duke Engineering and Services, Babcock &
Wilcox, Nukem Nuclear Technologies, Los Alamos Technical Associates, AEA
Technology, OHM Remediation Services, and M4. Phase 1A of the program covers the
first 20 months of the program and includes a $27 million award to each team to
prove the efficacy of their processes. Phase 1B covers waste processing of less
than 10% of the stockpile at Hanford over a five to seven year period. There can
be no assurances that Q-CEP will prove to be satisfactory to the DOE for
processing the Hanford waste or that, even if satisfactory, the DOE will award a
Phase 1B contract to the LMC team. There also can be no assurances that LMC will
submit a bid for Phase 1B. In addition, LMC is considering the use of other
waste processing technologies, in lieu of or in addition to Q-CEP, for all or
part of any Phase 1B contract. LMC may elect to include Q-CEP in the initial or
later portions of any Phase 1B contract if Q-CEP meets certain technical
criteria, to be established by MMT and LMC. There can be no assurances that
Q-CEP will be able to meet such criteria or that LMC will include Q-CEP in any
portion of any Phase 1B contract.

            Commercial Mixed Waste. In December 1995, MMT and M4 entered into an
agreement to expand M4's processing rights to include mixed wastes generated by
commercial customers in the United States. In March 1996, M4 entered into its
first agreement to process commercial mixed waste with Duke Power Company. Under
this agreement, M4 will process various types of mixed waste, including various
freon wastes and sludges, batteries and halogenated solvents. Since then, M4
also has entered into agreements with IES Utilities Inc., Baltimore Gas &
Electric Company and PECO Energy Company to process such companies' commercial
mixed waste. Mixed wastes from these companies are being or will be processed
using Q-CEP systems at the M4 Technology Center. These contracts have an
aggregate value of approximately $4.3 million.

            DOE Mixed Waste. In August 1996, M4 entered into an approximately
$700,000 contract with the DOE to conduct proof-of-process studies using Q-CEP
on a DOE mixed waste stream. Under the terms of the cost share contract, the DOE
will pay 67% of the cost and M4 will pay the remaining 33%. M4 completed these
tests in January 1997 and provided the results to the DOE in April 1997.

            DUF6 Market. In May 1995, M4 entered into a contract with USEC to
construct the DUF6 demonstration unit located at the M4 Technology Center. M4
provided results from the demonstration program to USEC in June 1996. As a
result of the M4 restructuring described below, MMT has assumed responsibility
for negotiations with USEC, and currently is negotiating an agreement with USEC.
The Company expects that any agreement with USEC would provide that the Company
or M4 would be primarily responsible for the design and construction of a
commercial-scale processing system, and that USEC would agree to furnish DUF(6)
for processing under a multi-year supply agreement. There can be no


                                       5
<PAGE>   7


assurances that these negotiations will be completed successfully or that the
Company or M4 and USEC will enter into an agreement to construct a DUF(6)
processing plant or an agreement to supply and process DUF(6).

            Chemical Weapons Demilitarization. In 1995, CEP was one of three
commercial, non-incineration technologies selected by the United States Army
from a list of 23 competing technologies for review of their ability to destroy
bulk chemical warfare agents (i.e., VX nerve and mustard agents) stored at the
Newport Chemical Activity in Indiana and the Aberdeen Proving Ground in
Maryland. During 1996, M4 worked with MMT, Bechtel National, Inc., Fluor
Daniel, Inc., and Battelle Memorial Institute to perform bench-scale testing of
a CEP unit located at a Battelle facility. The tests demonstrated that CEP
could achieve greater than or equal to 99.9999999% destruction removal
efficiency (DRE) on VX nerve agent and greater than or equal to 99.999999% DRE
on mustard agent, which in each case exceeded the Army's DRE requirement of 
99.9999%.

      In November 1996, the Army recommended that neutralization followed by
post-treatment, a technology sponsored by the Army, be piloted. Neutralization
involves mixing bulk chemical agents with dilutive chemicals in order to
neutralize the chemical agents. The remaining material, typically comprising
more than twice the volume of original chemical agent, must then be treated and
disposed. However, $40 million of the DoD's fiscal year 1997 budget has been set
aside to demonstrate at least two alternate technologies to incineration for the
disposal of assembled chemical weapons. Under the sponsorship of M4, MMT has
begun a program to demonstrate the feasibility of utilizing CEP to process
assembled chemical munitions containing a surrogate chemical agent in
preparation for a Request for Proposal from the Army anticipated in mid-1997.
There can be no assurances that MMT or M4 will receive any of the $40 million
budgeted by the DoD for the demonstration of alternative technologies.

      In September 1996, MMT, LMC and M4 entered into an agreement which
expanded M4's CEP license to include the demilitarization of Japanese chemical
weapons. In return for the expansion of the license, MMT received a $5 million
initial payment. Under the terms of this agreement, MMT also would receive an
additional $3.5 million upon completion of a technical demonstration by MMT of
the processing of one or more munitions shells containing surrogates of Japanese
chemical weapons. Under the terms of a letter of intent with LMC for the M4
restructuring described below, the new limited liability company to be formed by
MMT and LMC would assume M4's rights and obligations under this license. Payment
of the foregoing $3.5 million would be made from the limited liability company's
revenues.

      Also during 1996, M4 and Mitsubishi Corporation entered into a memorandum
of agreement to use CEP as the principal technology for destroying bulk chemical
agents located at small burial sites in northern China. The bulk agents along
with thousands of buried agent munitions were left by the Japanese Imperial Army
in China following World War II. Mitsubishi is the leading Japanese company
being considered to spearhead the cleanup of Japanese chemical weapons left in
China. To date, no request for proposals have been issued by the Japanese
government for the cleanup of such chemical weapons, and there can be no
assurances that, if such request for proposal is issued, Mitsubishi will be
awarded a contract for such cleanup.

            Restructuring of MMT/LMC Relationship. In March 1997, MMT and LMC 
announced that they had executed a letter of intent to restructure their
relationship with respect to the commercialization of CEP and other
technologies for the government and other waste markets. The objective of the
restructuring is to enable MMT and LMC to access target markets more
efficiently by eliminating many of the organizational redundancies associated
with the current M4 structure. LMC and MMT believe that the contemplated
restructuring also will enable them to better leverage LMC's expertise in
systems integration and MMT's ability to provide its CEP technology to target
markets. After the completion of the restructuring, LMC and MMT each would be
free to pursue projects formerly governed by the existing joint venture
agreements, subject to the requirements established by the proposed new
arrangements. The letter of intent contemplates five principal changes in the
relationship between LMC and MMT: (1) LMC would have the exclusive right to
lead and pursue contracts for the Hanford radioactive tanked waste cleanup
project described above, and MMT would provide directly to LMC certain
construction and development services with respect to CEP, (2) MMT and LMC
would form a new limited liability company to be their exclusive vehicle to
deliver processing services to customers in the chemical demilitarization
market worldwide, (3) MMT would have the exclusive right to lead and pursue
worldwide opportunities for processing DUF(6), (4) MMT would become the sole
owner of M4, which will continue to own and operate its primary remaining
asset, the M4 Technology Center, and (5) the Retech division of M4, which
provides plasma arc technology, would be transferred to LMC.

                  Hanford Project.  In connection with the proposed
replacement of M4 by MMT on the Hanford team, MMT would deliver a pilot-scale,
demonstration CEP plant to LMC in 1997 for a fixed 


                                       6
<PAGE>   8


price of $5 million. In addition, if the LMC team is awarded a contract under
Phase 1B of the Hanford cleanup program and CEP is used in the Phase 1B
performance, LMC would pay MMT a fee of $15 million and order a CEP production
plant meeting agreed upon criteria at a price to be negotiated. $5 million of
this fee would be payable on award of the contract and the remaining $10 million
would be payable upon timely delivery and acceptance of the CEP production
plant. MMT also would be entitled to an on-going royalty of 3.5% of all revenues
generated from the processing of waste in equipment supplied by MMT under the
Hanford contract. Pursuant to discussions between MMT and LMC in connection with
the negotiation of definitive agreements with respect to the restructuring, it
is anticipated that LMC would fund certain development work with respect to
Q-CEP for possible application to the Hanford project.

                  Chemical Weapons Demilitarization. The limited liability
company to be formed by MMT and LMC would have worldwide rights to commercialize
CEP for the chemical weapons demilitarization market. The limited liability
company would be owned 50/50 by LMC and MMT. MMT would be entitled to success
fees of up to an aggregate of $25 million in connection with the successful
deployment of CEP systems to process chemical weapons. The limited liability
company would have an initial term of five years.

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

                  DUF(6). In addition to the changes described above, MMT and
LMC have agreed in the letter of intent that MMT would have the exclusive right
to lead and pursue worldwide opportunities for processing DUF(6). LMC would have
the right to participate in this market on a case-by-case basis, subject to
mutual agreement of the parties, and would agree not to pursue this market for
five years except jointly with MMT.

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

      In connection with the proposed restructuring, LMC would forgive $15
million aggregate principal amount and all accrued interest under its line of
credit with M4, MMT would contribute $14.6 million in outstanding accounts
receivable to the capital of M4, and LMC and MMT generally would share equally
in substantially all of the costs of the restructuring.

      As of December 31, 1996, M4 had not earned any revenues related to the
Hanford radioactive tanked waste cleanup project, nor had M4 earned any
revenues from the processing of chemical weapons or DUF6. As of December 31,
1996, M4 had earned limited revenues from testing and development work performed
at the M4 Technology Center and from testing and development work related
to the chemical demilitarization and DUF6 markets. The Retech division of M4
has been the major source of revenue for M4 since its contribution to M4 in
April 1996.

      The restructuring described above is based on the terms set forth in a
non-binding letter of intent between MMT and LMC. Completion of the
restructuring is dependent upon a number of factors, including the negotiation
of definitive agreements and the approval of the Boards of Directors of MMT and
LMC. There can be no assurances that MMT and LMC will successfully consummate
the transactions described in the letter of intent.

      UNITED STATES DEPARTMENT OF ENERGY. In April 1997, the DOE chose the CEP
system that MMT is building at a Hoechst Celanese Corporation chemical plant in
Bay City, Texas to receive a $425,000 grant through the DOE's National
Industrial Competitiveness through Energy, Economics and Environment (NICE3)
Program. The program is designed to help innovative technologies with energy,
economic, and/or environmental benefits move into full commercialization. MMT's
proposal was one of 13 chosen by the DOE out of nearly 70 proposals in a
competitive solicitation process. An independent, third party technical team
reviewed each proposal in a three-phase process. The grant will be paid through
a cost-share contract, pursuant to which the DOE would contribute 40% up to the
$425,000 ceiling. Receipt of


                                       7
<PAGE>   9


this grant is conditioned upon the negotiation of such a contract with the DOE
or the Texas Natural Resource Conservation Commission which will be
administering the grant. There can be no assurances that MMT will be able to
successfully negotiate such contract.

      In September 1992, MMT submitted a three-phased proposal under the DOE's
Planned Research and Development Announcement ("PRDA") program. On January 19,
1993, MMT received a favorable determination regarding a $1.2 million
cost-sharing contract for a portion of the proposed PRDA program. The terms of
the contract were finalized in September 1993. Under the contract, MMT has
conducted trials and related activities at its research, development, testing
and demonstration facility in Fall River, Massachusetts to demonstrate the
applicability of CEP to contaminated scrap metals. In November 1993, the DOE
requested that the Company provide a proposal to enhance certain aspects of the
existing statement of work to provide for delivery of a more comprehensive final
report of technical results. This resulted in additional DOE funding of $9
million, bringing the DOE's total contribution to $10.2 million. In February
1995, the DOE issued a unilateral change order to increase the funding for an
undetermined amount with an initial ceiling of $5 million. In June 1995, the DOE
extended its contract for demonstrating CEP and increased its funding by an
additional $10 million, to a total of $25.2 million. In February 1996, the DOE
modified the contract funding for an undetermined amount with an initial ceiling
of $2 million. Additional funding through the end of 1996 brought the total
enhancement to $8 million for that year, and increased the DOE's total
contribution to $33.2 million. Activities under this contract have been
completed. MMT has contributed a total of $22.3 million in connection with the
cost-sharing contract. During 1996, revenue from the DOE accounted for
approximately 13% of the Company's total revenue. Other than the NICE3 grant
described above, the Company does not anticipate receiving research and
development funding from the DOE in 1997.

      UNITED STATES DEPARTMENT OF DEFENSE. In September 1996, the U.S. Air Force
Center for Environmental Excellence awarded approximately $480,000 to M4 to
conduct treatability studies on a broad range of hazardous wastes. The wastes
subject to the treatability studies represent approximately 84%, by volume, of
the wastes generated in Air Force operations. In March 1997, the contract was
amended to add treatability studies for two additional hazardous waste streams.
The contract amount was increased by approximately $333,000 in connection with
this modification. The studies are expected to be completed during the contract
period, currently ending December 31, 1997. In December 1996, an additional
$100,000 award was made under this contract with respect to the processing of
oils for the U.S. Navy which are contaminated with polychlorinated biphenyls
("PCBs"). This processing work is expected be completed by the end of 1997.

      In September 1994, the U.S. Army Armament, Research, Development, and
Engineering Center at Picatinny Arsenal, New Jersey awarded the Company $420,000
to fund demonstration of CEP's applicability to conventional weapons components.
Trials under this contract demonstrated that the processing of conventional
munitions, smoke and dye agents and propellants in the CEP system resulted in
the destruction of the hazardous constituents to high environmental standards
and the partitioning of the elements into recoverable materials. Activities
under this contract were successfully completed in 1996.


      The Company's existing government contracts can generally be canceled,
delayed or modified at the sole option of the government and are generally
subject to annual funding limitations and public sector financing constraints.
The Company believes that any future government contracts will be structured
similarly. In addition, under the terms of future government contracts, if any,
the Company may be required to grant the federal government greater rights with
respect to the Company's intellectual property than the Company would grant
private parties. As a result of engaging in the government contracting business,
the Company is subject to audits and investigation by government agencies. As
described below under Item 3, the Company and M4 currently are responding to
subpoenas issued by the Office of Inspector General of the DOE. The Company also
faces the risks associated with government contracting, which could include
substantial civil and criminal fines and penalties. In addition to potential
damage to the Company's business reputation, the failure by the Company to
comply with the


                                       8
<PAGE>   10


terms of any of its government contracts could result in the Company's
suspension or debarment from future government contracts for a significant
period of time. All of the foregoing risks associated with government
contracting may also apply to M4 with respect to its government contracts.

Industrial Hazardous Waste Market

      Hoechst Celanese Corporation. Pursuant to agreements signed in May 1995
with Hoechst Celanese Corporation ("HCC"), one of the largest U.S. based
chemical companies, MMT is constructing a CEP facility (the "Bay City CEP
Facility") at HCC's Bay City, Texas chemical plant. This facility will be
financed, owned and operated by MMT or a wholly-owned subsidiary of MMT. The CEP
system being installed at the Bay City CEP Facility will have an initial
capacity to process up to approximately 30,000 tons of feedstocks from HCC's
Texas plants and third-party generators, although this system currently is
permitted to process only 15,000 tons per year. Any increase in the amount of
feedstocks which can be processed in this CEP system is contingent upon
sufficient commercial interest, and application for and receipt of all necessary
regulatory, community and other approvals. The project site is being designed to
support potential additional future expansion of the Bay City CEP Facility. The
facility will produce synthesis gas, an industrial feedstock to be used by HCC
in its chemical processing, and aqueous hydrochloric acid for sale to third
parties. The Company expects that commercial operation of this facility will
begin in the second half of 1997, but there can be no assurances as to the
successful or timely deployment of this facility.

      MMT has signed one agreement and three letters of intent with four other
major chemical manufacturers to process feedstocks from their existing
operations at the Bay City CEP Facility. The agreement and letters of intent
cover an aggregate of up to approximately 20,000 tons of feedstocks per year.
The Company also has entered into a ten-year contract with a major hydrochloric
acid distributor under which the distributor will purchase 85 to 100 percent of
the hydrochloric acid produced at the Bay City CEP Facility, provided that such
acid meets agreed specifications. Under the terms of their letters of intent,
two of the chemical manufacturers have agreed to purchase hydrochloric acid
produced from the processing of their feedstocks at the Bay City Facility,
provided that such acid meets agreed specifications. Pursuant to the agreements
with HCC mentioned above, HCC has agreed to purchase all of the synthesis gas
produced at the Bay City CEP Facility, provided that the gas meets agreed
specifications. There can be no assurances that the Company will enter into
binding agreements to process feedstocks based on the letters of intent or that
the Company will be able to produce hydrochloric acid or synthesis gas meeting
the required specifications.

      Nichimen Corporation and NKK Plant Engineering Corporation. In February
1996, MMT, Nichimen Corporation, one of Japan's major trading companies, and NKK
Plant Engineering Corporation, one of Japan's largest engineering providers of
municipal waste systems ("NKP"), signed a letter of intent to form a joint
venture to process fly ash produced by Japanese municipal solid waste
incinerators. A definitive agreement to form this joint venture was executed in
October 1996 by the Company, Nichimen and NKP. The agreement grants the joint
venture the exclusive right to introduce CEP to the Japanese municipal
incinerator ash market. It is anticipated that, once formed, the joint venture
will employ MMT's proprietary Cerex-CEP technology to process and recycle
incinerator ash to recover ceramic and metal products. Under the agreement, the
Company will own 49% of the joint venture and each of Nichimen and NKP will own
25.5% of the joint venture. The joint venture will be formed as a Japanese
limited liability company and will be capitalized with approximately $1
million, contributed by each partner in proportion to their ownership interest.
The funds necessary to purchase and operate the initial CEP system described
below will be loaned to the joint venture by each partner in proportion to
their ownership interest. In addition, if agreed by all of the partners, each
partner has agreed to guarantee the joint venture's working capital
requirements, up to a maximum of $2 million.

       In consideration for the grant of the exclusive license to the joint
venture, the Company will receive a two percent royalty on all revenues, and
will receive a $12.5 million licensing fee, to be paid from the joint venture's
profits. Each of the joint venture, Nichimen and NKP have agreed to assign to
the Company all intellectual property rights related to CEP which they may
develop during the term of the agreement. The Company has agreed to provide
research and development and certain other technical services to the joint 
venture and its customers and to sell certain CEP components to the joint 
venture and its customers, at specified rates.

      The joint venture agreement has a term of ten years, unless extended by
the mutual agreement of the partners. The agreement may be terminated by any
partner if the joint venture sustains more than $14,500,000 in losses.

      The agreement provides that the joint venture will purchase an initial
CEP system to be delivered in the first quarter of 1998. The Company expects
that this system will be sold for a fixed price of $7.9 million and that final
payment for such system will be contingent upon the successful completion of a
performance test once the system has been installed in Japan.

      The parties expect that the joint venture will purchase a minimum of 29 
CEP systems from the Company over the first ten years of the joint venture's
operations, including the initial CEP system. There can be no assurances that
the joint venture will order any CEP systems from MMT or that such systems, if
ordered and delivered to Japan, will be able to successfully process and
recycle incinerator ash. In addition, the agreement is subject to final
approval from the Japanese government, and there can be no assurances that such
approval will be received.

      Celanese Mexicana, S.A. de C.V.  In January 1996, MMT and Celanese
Mexicana, S.A. de C.V. ("CelMex"), Mexico's largest private sector chemical
company, signed a letter of intent to construct a CEP


                                       9
<PAGE>   11


system to process and recycle manufacturing wastes at CelMex's chemical
production facility in Veracruz, Mexico. The proposed CEP system will be
designed to process wastes produced by CelMex and other Mexican companies.
CelMex will purchase the synthesis gas produced by the CEP system as a raw
material in its chemical manufacturing processes. Under the letter of intent,
CelMex would provide the site and infrastructure for the CEP system and MMT
would construct, own and operate the facility. Development of the CEP system
pursuant to this letter of intent is subject to a number of conditions,
including the negotiation and execution of definitive agreements. There can be
no assurances that the parties will be able to negotiate mutually acceptable
agreements to develop the proposed facility. In addition, MMT may sell all or a
portion of its equity interest in this facility and intends to obtain third
party financing for the construction of this facility. If MMT is unable to sell
such equity interest or obtain such financing on acceptable terms, it may elect
not to proceed with the development of this facility.

COMMERCIAL DEVELOPMENTS -- ONGOING RELATIONSHIPS

      Since the Company's formation it has entered into several strategic
alliances with companies that have specialized expertise. The Company believes
that these relationships assist the Company in its planned commercialization of
CEP, either by assisting the Company in marketing to particular industry groups,
or by providing key services in connection with the Company's development and
application of its CEP technology, such as assistance with obtaining insurance
or project finance, or the provision of engineering and construction expertise.
The Company may enter into similar long-term relationships in the future.

      Uhde GmbH. In February 1996, MMT entered into a non-exclusive sales
representative and services agreement with Uhde GmbH. Uhde, based in Dortmund,
Germany, is one of the world's leading engineering and construction companies.
Under the agreement, MMT and Uhde will collaborate to market CEP to Uhde's
worldwide customer base. Uhde has committed to identify and sell a minimum of
nine CEP projects outside the United States over a four-year period. If Uhde
fails to meet these minimum requirements, MMT has the right to terminate the
agreement. Uhde will provide facility engineering and design site construction,
equipment installation and project management, and MMT will provide marketing
assistance, CEP system design and fabrication, operator training and ongoing
operational support, as needed, to Uhde's customers. Uhde and MMT have agreed to
focus their joint efforts on addressing a wide range of markets including
chlorinated organic chemical wastes, chemical weapons demilitarization projects,
post-consumer plastics and electronic components, municipal waste water
treatment sludges and waste incinerator ash. To date, Uhde has not sold any CEP
projects and there can be assurances that it will be able to do so in the
future.

      The Electric Power Research Institute ("EPRI"). In November 1995, MMT
entered into an agreement with EPRI to support the application of CEP. Over the
five-year term of the agreement, EPRI, in conjunction with numerous utilities
and their process industry customers, plans to develop collaborative programs
for CEP demonstrations. EPRI will fund up to $25 million in matching research
grants made to member utilities working with industrial process customers in
their service areas to demonstrate CEP. In exchange for this commitment, EPRI
received a warrant to purchase up to 100,000 shares of MMT common stock at an
initial exercise price of $23.375. The warrant will vest in increments upon the
closing of contracts for CEP plants for which EPRI has provided minimum levels
of funding and upon customer acceptance of such plants. To date, none of the
EPRI warrants have vested. The Company expects that the EPRI relationship will
assist the Company in marketing its CEP technology to utilities and process
industry customers.

      American Re-Insurance Company and Am-Re Services. In May 1993, MMT entered
into a set of related agreements with American Re-Insurance Company and its
affiliate, Am-Re Services, Inc. In addition, MMT was obligated to perform
certain services for Am-Re Services through December 31, 1993. Pursuant to these
agreements, American Re-Insurance Company purchased 438,885 shares of MMT common
stock for $5.0 million and Am-Re Services agreed to provide services to MMT
relating to obtaining environmental impairment liability insurance and project
financing for the first five commercial CEP facilities to be developed by MMT.
In exchange for these services, Am-Re Services was granted


                                       10
<PAGE>   12


warrants to purchase an aggregate of 375,000 shares of common stock at prices
ranging from $12.25 per share to $18.37 per share. To date, none of these
warrants have vested because the Company has not obtained environmental
impairment liability insurance or project financing with the assistance of Am-Re
Services. The Company expects that, as it develops additional CEP plants, Am-Re
Services will provide assistance to the Company related to obtaining
environmental impairment liability insurance and project financing for such CEP
plants.

      Fluor Daniel. Since September 1992, MMT and Fluor Daniel, Inc. or Fluor
Daniel Environmental Services, Inc. ("Fluor Daniel"), an international
engineering and construction firm, have been parties to a series of agreements
pursuant to which Fluor Daniel has provided engineering and construction
services, feasibility studies, designs, cost estimations and other services in
support of CEP plants and potential CEP applications. During 1994 and 1995,
Fluor Daniel invested $5.2 million payable by MMT for such services in MMT
common stock. Fluor Daniel and MMT previously had been parties to an agreement
which required MMT to use Fluor Daniel for engineering and construction services
for CEP plants being built by MMT. In August 1996, Fluor Daniel and MMT amended
this agreement to provide that Fluor Daniel would provide such services to MMT
on a case-by-case basis, at each party's mutual discretion. During 1996, Fluor
Daniel provided substantial engineering and construction services to MMT for the
Bay City CEP Facility and the M4 Technology Center.

TECHNOLOGICAL DEMONSTRATIONS AND TESTING OF CEP

      In order to further demonstrate CEP's Elemental Recycling capability on a
variety of prospective customer feedstocks, MMT has constructed an 86,000 square
foot research, development, testing and demonstration facility in Fall River,
Massachusetts that is equipped with several commercial-scale CEP systems (the
"Fall River Facility"). Since February 1993, through internally and
customer-funded TDPs, the Company has demonstrated CEP's ability to break down
feedstocks and recover products in laboratory, bench-scale, pilot-scale and
commercial-scale trials in its Fall River Facility. These tests and
demonstrations on feedstock samples representative of those of prospective
customers have shown the safety and reliability of CEP for a wide range of
chemical components and physical forms.

      CEP and its underlying technologies have been demonstrated in tests on
many materials from simple compounds, such as paraffins and alcohols, to complex
materials containing toxic metals, alkali metals, halides, cyanides, fluorinated
species and polyaromatic hydrocarbons (including PCBs). These demonstrations
have included wastes that are classified as hazardous or toxic under RCRA
(including chemical weapons agents), low level radioactive wastes, mixed wastes,
and surrogate hazardous wastes in the form of gases, liquids, slurries,
suspensions, pumpable sludges, and solids. MMT has successfully completed
customer-sponsored trials in which numerous customer-established success
criteria for closed-loop recycling were met or surpassed.

      The Company's technological demonstrations are complemented by additional
external research programs, some of which are conducted by members of MMT's
Technical Advisory Board.

      In addition to the operating demonstrations described above, MMT has
developed physical models and computer simulations that are used to model CEP
systems functions such as feed addition, molecular dissolution, refractory wear,
vitreous material characteristics and reactor design. Prior to running
experimental trials on particular feedstock, MMT uses such models to predict
capital and operating costs and system performance.

      To date, the testing of CEP largely has been limited to trials conducted
under controlled testing conditions. Certain commercial-scale tests of CEP have
been conducted and the Company has developed computer simulations which it uses
to model and predict various CEP system functions. The Company currently is
operating its Q-CEP facility in Oak Ridge, Tennessee and M4 has operated one
mixed waste system at the M4 Technology Center, and is conducting start-up
operations and testing on a second, larger mixed waste system. However, no
demonstration has yet been made that a commercial CEP


                                       11
<PAGE>   13


system, once installed and operated by MMT or M4 or at a customer's location,
will process feedstocks and recover commodity and specialty products of
commercial quality and in significant quantities.

      The Company is continuing its research and development efforts to further
enhance the functionality of its CEP systems, especially in areas such as
removal of ceramic product from the CEP reactor and the addition of large solid
feeds to the CEP reactor, with the goal of making CEP systems more efficient for
processing a wide range of wastes and waste forms and making CEP systems more
cost-effective. The Company expects that broad deployment of CEP into certain of
its target markets will require additional enhancements and functionalities that
are currently being further developed by MMT. MMT's ability to successfully sell
CEP systems for a wide range of waste streams and waste forms in such markets
could be materially adversely affected if the Company is unable to adequately
develop such additional enhancements and functionalities. During the fiscal
years ended December 31, 1996, 1995 and 1994, the Company spent $37.5 million,
$25.3 million and $25.2 million, respectively, on research and development, of
which $26.2 million, $11.0 million and $14.4 million, respectively, was funded
by the Company.

The Fall River Facility

      The primary use of MMT's Fall River Facility is to perform TDPs that
demonstrate CEP's Elemental Recycling capability on a variety of feedstocks,
including samples of customers' materials. MMT believes that the Fall River
Facility serves to further the development of CEP technology and MMT's
associated intellectual property estate and assists in facilitating favorable
customer and regulatory acceptance of the process. The Fall River Facility also
is used to conduct training programs for MMT employees and customers.

      The 86,000 square foot Fall River Facility contains a 48,000 square foot
recycling area which includes a materials preparation area, feedstock storage,
raw material storage, recovered material storage and a test laboratory. The Fall
River Facility houses commercial-, pilot- and bench-scale CEP units which are
used for treatability and feasibility studies, and also houses physical models
of CEP units. These models are used to analyze injection patterns and to
simulate flow dynamics and various reaction patterns within the molten metal
bath.

Recoverable Products

      Laboratory, bench-scale, pilot-scale and commercial-scale trials,
including trials conducted at the Company's Fall River Facility, have
demonstrated that CEP has the potential, through Elemental Recycling, to recover
commodity and specialty products, such as industrial gases, ceramics and metals,
from feedstocks. MMT's test results from demonstration and treatability trials
have shown that greater than 90% of the feedstocks processed in these trials was
able to be recycled into products. Based upon these test results and commercial
specifications for CEP products, the Massachusetts Department of Environmental
Protection has issued MMT recycling certifications for CEP of heterogeneous
inorganic and organic waste streams, including RCRA-listed waste streams. Based
on the elemental composition of particular feedstocks, MMT has demonstrated that
CEP systems can be customized to make specific products by adding different
reactants or by varying the composition of the molten metal bath. CEP is
designed to permit recovered products to be re-used as raw materials by the
feedstock generator in potential closed-loop applications or to be sold to other
industrial customers.

      Some materials produced using CEP may have little to no commercial value,
and may be considered wastes. Certain of such wastes may be classified as
hazardous wastes (and may need to be handled as such) under current United
States environmental regulations. Based on experimental trials with hazardous
waste streams, MMT anticipates that the volume of any such unsaleable materials
will be a small portion of the initial feedstock volume and will be
substantially less than the residual waste (including ash) generated by
alternative technologies.


                                       12
<PAGE>   14


      With respect to radioactive wastes, the Company expects that the volume of
reusable products generated from processing such wastes with Q-CEP will be lower
compared with other applications of CEP and expects that the volume of residual
waste streams will be greater. Any such residual waste which is classified as a
low-level radioactive waste will need to be handled as such under current United
States environmental regulations. Operations at MMT's Q-CEP facility in Oak
Ridge, Tennessee, as well as experimental trials have shown, however, that Q-CEP
substantially decreases the volume of such radioactive wastes and contains the
radioactive elements in a stable, self-shielding form.

INTELLECTUAL PROPERTY AND PROPRIETARY TECHNOLOGY

      MMT has a comprehensive program for the protection of its intellectual
property. This program includes, among other things: established procedures
including notebooks and forms for documenting, evidencing and disclosing all MMT
inventions to management; an Intellectual Property/Patent Management Team which
meets regularly to discuss intellectual property issues; a system for
continuously monitoring patents issued to, and patent applications filed by,
relevant third parties; a program of seminars for employees on intellectual
property topics; a recognized intellectual property law firm on retainer; a
senior in-house patent counsel; a patent administrator and other personnel
dedicated to assisting in the preparation and prosecution of MMT's patents;
personnel policies and agreements requiring disclosure by employees of all
inventions and protection of confidential information; and agreements with all
technical and scientific employees providing for the assignment of inventions
made by such employees to MMT.

      As of December 31, 1996, MMT owned 104 United States and foreign patents,
and had pending an additional 203 United States, Japanese, European and other
foreign national patent applications relating to CEP. MMT also has many
invention disclosures describing inventions by employees, many of which could be
the basis for future patent applications.

      MMT's intellectual property estate also contains a number of sophisticated
computer models used to predict the thermodynamic, kinetic and physical
transport properties of the CEP system, including tuyere injection, multiphase
jet flow and turbulent diffusion, equilibrium partitioning and kinetic
limitations, product formation and system design. Some of such computer models
include components which are the subject of non-exclusive licenses from computer
software vendors. MMT's computer models are used to identify optimal designs and
operating conditions for specific processing applications. MMT has demonstrated
the accuracy of many of these computer models through actual experimentation.

      To protect its trade secrets and other unpatented proprietary information
in its product development activities, MMT's employees, consultants and
contractors are required to enter into agreements providing for confidentiality
and MMT's ownership of such trade secrets and other unpatented proprietary
information originated by them while in MMT's employ.

      There can be no assurance that any patents will issue on any of MMT's
patent applications or that any patents will provide meaningful protection
against infringement of the Company's technology. There also can be no assurance
that any of MMT's confidential non-disclosure agreements will provide meaningful
protection of MMT's confidential or proprietary information in the case of
unauthorized use or disclosure.

      The Company has ten service marks or trademarks registered, and several
applications to register, with the U.S. Patent and Trademark Office for terms
used in conjunction with MMT's services in material processing, hazardous and
non-hazardous waste treatment, and resource recovery. Registered marks include:
MMT(R), The Elemental Solution(R), Elemental Solution(R), MMT Catalytic
Extraction Processing(R), Molten Metal Technology (and design)(R),
Quantum-CEP(R), Q-CEP(R), and the design of certain MMT logos. Applications for
service marks or trademarks include: Hyco-CEP(TM) and Cerex-CEP(TM).

ENVIRONMENTAL MATTERS

Environmental Laws and Regulations Creating a Market for CEP

      Various environmental protection laws have been enacted and amended during
recent decades in response to public concern over the environment. MMT's
operations and those of its customers are subject to these evolving laws and the
implementing regulations. MMT believes that the obligations to comply with the
requirements of these laws contribute to the demand for its services.

      The environmental legislation and policy which the Company believes are
potentially applicable to CEP operations in the United States include RCRA,
TSCA, the Federal Water Pollution Control Act of 1972, the Clean Air Act of
1970, as amended, the Hazardous and Solid Waste Amendments of 1984, the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended, the Superfund Amendments and Reauthorization Act and the Pollution
Prevention Act of 1990, and various state analogs to these federal laws.
Additional provisions which may be applicable to Quantum-CEP technology include
the Atomic Energy Act of 1954, the Federal Facility Compliance Act of 1992, the
Low-Level Radioactive Waste Policy Amendments Act of 1985, the Department of
Energy Orders, Policy and Guidance, the Nuclear Regulatory Commission Regulatory
Policy and Guidance, and their state analogs. These provisions regulate the
management and disposal of radioactive, hazardous and non-hazardous wastes,
control the discharge of pollutants and radionuclides into the air, land and
water, provide for the investigation and remediation of contaminated land and
groundwater resources and establish a pollution prevention program. Many of
these laws have international counterparts, particularly in Europe and elsewhere
in North America.

Environmental Permitting Implications

      To maximize the market acceptance of CEP technology, MMT has chosen to
focus certain initial project efforts on the development of systems whose
feedstocks and designs are most likely to qualify for exemptions or favorable
regulatory treatment. These projects involve: (i) systems for processing
feedstocks that are not classified as hazardous wastes and are not subject to
RCRA permitting requirements; (ii) systems that handle feedstocks in a manner
that may qualify such materials for exclusions from RCRA regulation (e.g., a
closed-loop process whereby secondary materials will be returned to the original
manufacturing process in which they were generated or processing of waste
materials as feedstocks to manufacture valuable products); (iii) systems that
may qualify for an exemption from RCRA permitting requirements (e.g., systems
involving bona fide recycling of hazardous wastes); (iv) systems that provide
for significant volume reduction and stable final form for low-level radioactive
waste to allow for increased disposal capacity or a more manageable form for
storage, or both; and (v) systems that provide for volume reduction, stable
final form and recycling for mixed waste streams. MMT also would consider use of
CEP as part of the treatment train in previously permitted RCRA treatment
facilities for which MMT believes that only a permit modification would be
required.

      The permitting burden on a facility utilizing CEP will depend on the
nature of the feedstock (including whether it is classified as a solid waste or
hazardous waste), the configuration of the process at the particular facility,
the manner in which product is recovered from the waste and the type of waste
residuals created by the process.

BDAT Equivalency Determinations

      Pursuant to EPA environmental regulations, the processing of hazardous
waste that is to be disposed of on land must be accomplished using the Best
Demonstrated Available Technology ("BDAT"). In February 1996, EPA issued a BDAT
equivalency determination for CEP for all RCRA-listed waste streams which were
previously required to be incinerated. As a result, generators are permitted to
meet their BDAT requirement by using CEP for these waste streams. In connection
with a July 1995 equivalency determination for chlorinated organic wastes, the
EPA noted that dioxin, a toxic and harmful substance, was not detected at
EPA-promulgated regulatory levels in CEP demonstrations. The


                                       14
<PAGE>   16


Company believes that the EPA's BDAT equivalency determinations confirmed that
CEP is fundamentally different from incineration, and further confirms that use
of CEP supports the EPA's efforts to minimize cross-media contamination
(transfer of contaminants to air and water from solid wastes) and to reduce the
quantity of residuals for land disposal.

Research Facility License

      On February 27, 1995, the Massachusetts Department of Environmental
Protection (the "MADEP") issued a Research Facility License for recycling
activities (the "License") that regulates hazardous waste recycling research
activities at the Fall River Facility. The License became effective on March 20,
1995, and replaced the original R&D Recycling Permit for the Fall River
Facility, which was issued in September 1993. The License has a term of five
years.

      Under the terms of the License and the Demonstration Permit for solid
wastes issued in September 1993 (the "Permit"), most solid and hazardous wastes,
including RCRA-listed hazardous wastes, may be stored and processed at the Fall
River Facility, subject to limits and conditions specified in the License and
the Permit. The License requires MMT to provide a notice to the MADEP, the Fall
River Fire Department and the Fall River Board of Health at least 14 days prior
to conducting hazardous waste recycling demonstrations greater than 250
kilograms/day. This notice must contain a summary of applicable treatability
study data and other information. The Permit requires review and approval by the
MADEP prior to solid waste recycling demonstrations.

      In November 1995, the EPA granted an approval to allow the Company to
perform testing on wastes containing PCBs pursuant to the EPA's authority under
TSCA. Also, in November 1995, the MADEP modified certain of the permits for the
Fall River Facility to allow the Company to store and process PCBs. MMT operates
the Fall River Facility pursuant to all necessary permits as well as an
Agreement with the City of Fall River (the "Fall River Agreement"), which first
became effective on March 17, 1993. In April 1995, the Fall River Agreement was
modified and amended to reflect the requirements of the License. In November
1995, the Fall River Agreement was further amended to add provisions related to
the processing of PCBs.

Permits for Commercial Facilities

      With respect to the first commercial facilities constructed or under
construction by the Company, the Company and M4 have been successful in
obtaining the permits necessary to construct and operate these facilities. In
February 1996, the Texas Natural Resource Conservation Commission ("TNRCC")
determined that CEP is distinct from incineration and other combustion and
thermal treatment processes, and approved CEP as a RCRA-exempt recycling
technology. This approval means that CEP plants in Texas would not need to
obtain RCRA permits prior to the construction or operation of CEP plant. In
September 1996, the Louisiana Department of Environmental Quality provided a
regulatory determination to a prospective customer of MMT indicating that an
on-site CEP unit installed at the customer's facility would be exempt from RCRA
permitting requirements and Toxic Release Inventory (TRI) emissions reporting.

      In January 1997, MMT received approval from the TNRCC to receive a class
of secondary materials for processing at the Bay City CEP Facility as non-RCRA
regulated materials. This approval means that feedstocks fitting the
characteristics approved by TNRCC for processing will not be treated as
hazardous materials under RCRA and will be exempt from TRI emissions reporting.
This regulatory designation should streamline processing of materials at the
facility and should provide a competitive advantage to customers utilizing the
facility for management of their secondary materials.

      In the case of the Quantum-CEP facility constructed by MMT and SEG, the
Tennessee Department of Environment and Conservation ("TDEC") issued to SEG an
air permit in May 1995 (amended in October 1995) which allowed the installation
and initial operation of the CEP equipment and related air pollution control
devices at the facility. In addition, in November 1995, SEG received a


                                       15
<PAGE>   17


radioactive materials license from TDEC that allows the possession, use and
storage of radioactive materials at the Quantum-CEP facility. This license was
transferred to MMT Tennessee in December 1996 in connection with the acquisition
of SEG's interest in the Q-CEP facility.

      In September 1995, TDEC issued an air permit to M4 which allowed the
installation and initial operation of the CEP systems at the M4 Technology
Center. In addition, in November 1995, TDEC issued a radioactive materials
license to M4 that allows the possession, use and storage of radioactive
materials at the M4 Technology Center. TDEC also issued an approval in December
1996 allowing the processing and recycling of mixed waste organic liquids and
sludges in connection with the mixed waste processing activities being performed
by M4 for the DOE and commercial customers.

COMPETITION

      MMT defines the market for its CEP technology as the recycling, processing
and volume reduction of certain radioactive, hazardous and non-hazardous wastes
and industrial by-products. MMT is aware of some competition from companies
recycling hazardous wastes, but its primary competition comes from companies
that provide radioactive and hazardous waste treatment and disposal services.
The predominant waste treatment and disposal methods include landfilling,
deep-well injection, incineration, plasma, vitrification, or other thermal
treatment methods, on-site containment (including industrial lagoons), and
release into the environment. The hazardous waste treatment and disposal
industries are fragmented and characterized by a number of large and small
companies. Competition is based primarily on cost, regulatory and permit
restrictions, technical performance, dependability and environmental integrity.
The Company believes that CEP will be able to compete favorably on the basis of
these factors. Many technology developers also have begun to focus on the
government markets as new opportunities continue to evolve. Some of these
technologies may also be applied to the commercial radioactive waste and
hazardous waste markets. The government is evaluating a wide variety of
technologies, with the objective of identifying alternatives that offer benefits
over conventional methods, such as incineration. Many of MMT's competitors have
substantially greater financial and technical resources than MMT.

      For most waste streams, CEP is designed to provide recovery of products
and re-use by generators or sale of such products to other commercial and
government customers. CEP's potential cost advantage over conventional waste
treatment and disposal methods is dependent, in part, on such re-use or sale.
MMT anticipates that the price of such products will be established on the basis
of competition with other large or small producers of raw materials and recycled
products which may have greater financial resources and experience in connection
with the production and marketing of such materials and products than MMT or its
customers.

EMPLOYEES

      As of December 31, 1996, the Company had 481 full-time employees. The
Company believes that it has been successful in attracting experienced and
capable process development, engineering, operations and management personnel.
The Company's growth and expansion plans depend in large part upon its ability
to continue to attract and retain highly skilled scientific, managerial,
manufacturing, operations and marketing personnel.

      All of the Company's employees have entered into agreements with the
Company requiring them not to disclose the Company's proprietary information,
assigning to the Company all rights to inventions made during their employment
and prohibiting them from competing with the Company.

      None of the Company's employees is covered by collective bargaining
agreements. The Company considers relations with its employees to be good.

      In May 1997, the Company announced that as part of a restructuring
designed to further MMT's transition from research and development into
commercial operations, it had eliminated 77 positions (out


                                       16
<PAGE>   18


of approximately 530), primarily at the Company's corporate headquarters in
Waltham, Massachusetts, and at the Fall River Facility. Most of the eliminations
were from MMT's design and development area. In November 1996, the Company
announced that as part of a restructuring to more efficiently pursue
opportunities in priority markets, it had eliminated 58 (out of 480) positions,
primarily at the Company's corporate headquarters in Waltham, Massachusetts.
Most of the eliminations were staff positions from finance and administration,
sales and marketing, and government and regulatory affairs. The Company intends
to continue hiring to fill positions that are critical to meeting the Company's
technology delivery schedule.

ITEM 2. PROPERTIES

      The Company currently leases approximately 77,000 square feet of office
space in Waltham, Massachusetts, that it uses as its corporate headquarters,
under a seven-year lease expiring in 2003. This lease has a five-year extension
option. The Company also has entered into a lease for an additional
approximately 77,000 square feet of office space in the same office park in
Waltham. This lease also has a seven year term with a five year extension
option. The Company currently does not intend to occupy this additional space
and is in the process of subleasing it to third parties. Currently, more than
one third of this building has been subleased at rents in excess of the rent
which the Company is required to pay, and the Company is negotiating subleases
for the remaining space. The Company also has subleased its prior corporate
headquarters in Waltham through the duration of the lease term. In addition, the
Company has smaller offices in Washington D.C., Oak Ridge, Tennessee, Houston,
Texas, Bay City, Texas and Denver, Colorado that are leased on a short-term
basis.

      The Company has a ten-year lease expiring in 2004 with the Greater Fall
River Development Corporation for the Fall River Facility located on ten acres
of land in Fall River, Massachusetts. The lease includes three ten year
extension options, exercisable at the option of the Company. The Fall River
Facility has approximately 86,000 square feet of usable space, of which
approximately 34,000 square feet is used for office and training and the
remainder for research and development operations, warehousing and laboratories.
The Company also has leased approximately 19,800 square feet of office, storage
and warehouse space near the Fall River Facility. In July 1996, the Company
purchased approximately five acres of land adjacent to the Fall River Facility.
This land could be used for potential future expansion of the Fall River
Facility.

      The Company has a lease with Hoechst Celanese Chemical Group, Inc. for the
land on which the Bay City CEP Facility is being constructed. The lease has a
term of ten years from the date that the facility begins commercial operation.
The lease will be automatically extended for as long as MMT maintains the
permits necessary to operate the facility and produces synthesis gas meeting
agreed specifications.

      In connection with the acquisition of SEG's interest in the Q-CEP facility
in Oak Ridge, Tennessee, MMT Tennessee purchased the approximately six acre
parcel upon which the facility is located. MMT Tennessee also is occupying an
office building located adjacent to the Q-CEP facility pursuant to a license
which was acquired from SEG. This license has a one year term, expiring in
January 1997, but MMT Tennessee has the right to negotiate a longer term lease
for the building. During the one year period ending in December 1997, MMT
Tennessee also has the right to occupy and use a portion of SEG's facility in
Kingston, Tennessee for the conduct of certain wet waste processing activities.
Thereafter, MMT Tennessee may move the personnel and equipment used for such
activities to the Q-CEP facility site or may attempt to negotiate an extension
to the one year occupancy period.

      As part of the acquisition of wet waste processing assets from VECTRA, MMT
Tennessee acquired a maintenance facility located on approximately 16 acres of
land in Columbia, South Carolina. MMT Tennessee will continue to operate this
facility in connection with the wet waste business.

ITEM 3. LEGAL PROCEEDINGS

      In February and March 1997, purchasers of the Company's common stock filed
five purported class action suits against the Company and certain of its present
and former directors and executive officers in the United States District Court
for the District of Massachusetts. The first suit, filed on February 12, 1997,
and the fifth suit, filed on March 28, 1997, name the Company and Messrs.
William M. Haney, III, Christopher J. Nagel, Benjamin T. Downs, Victor E. Gatto,
Jr., Ian C. Yates, John T. Preston and Maurice F. Strong as defendants. The
other three suits, filed on February 13, February 20, and February 27, 1997,
each name the Company and Messrs. Haney, Nagel, Preston and Strong as
defendants. The complaints variously allege that the Company and the individual
defendants made false and misleading statements concerning the development and
commercialization of CEP and the availability of research and development
funding from the DOE, and disseminated financial statements not prepared in
accordance with generally accepted accounting principles, in violation of
Section 10(b) of the Securities Exchange Act of 1934 and state law. The
complaints variously assert that the alleged false or misleading statements were
made to inflate the price of the Company's common stock in order to facilitate
its March 1996 offering of convertible subordinated notes, to reduce the number
of shares contributed to M4 to match an investment by M4's co-owner, to enhance
the value of stock or options held by the individual defendants, and to increase
the price of stock sold by the individual defendants. Each of the suits seeks
compensatory damages for alleged losses during the class periods (September 26,
1995 through October 21, 1996 in the first suit, March 28, 1995 through October
18, 1996 in three of the suits, and September 26, 1995 through October 20, 1996
in the fifth suit) as well as fees and costs. The suits are at an early
procedural stage. While the Company has not yet filed answers to the complaints,
the Company intends to deny liability. However, the ultimate outcome of the
litigation cannot be determined at present.

      In April 1997, the Company and M4 received subpoenas from the Office of
the Inspector General ("OIG") of the DOE which request various Company and M4
information and records. The OIG has not informed the Company or M4 of its
reasons for requesting such information and records.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS

   There were no matters submitted to the Company's security-holders in the
fourth quarter of fiscal 1996.

      As of May 19, 1997, there were 939 holders of record of the Common Stock.
On May 19, 1997, the closing bid price of the Company's Common Stock, as quoted
by the NASDAQ National Market, was $7.25 per share. The Company has never
declared or paid cash dividends on its Common Stock and does not anticipate
doing so in the foreseeable future.

      In May 1996, the Company issued $143,750,000 of its 5.50% Convertible
Subordinated Notes Due 2006 (the "Notes"). The Notes are convertible at the
option of the holder into shares of the Company's Common Stock at a conversion
price of $38.75 per share. The Notes were offered and sold to qualified
institutional buyers in accordance with the exemption from the registration
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
provided by Rule 144A and to a limited number of other institutional accredited
investors (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities
Act) that executed and delivered a representation letter to the Company. In
addition, certain of the Notes were sold outside the United States in accordance
with procedures intended to support the Company's reliance on the exemption from
the registration requirements of the Securities Act provided by Regulation S.
The principal underwriters for this offering were Lazard Freres & Co. LLC, Alex.
Brown & Sons Incorporated and Oppenheimer & Co., Inc. The Notes were purchased
by these underwriters at a purchase price of 100% of principal amount less an
aggregate offering discount of 3.0% of the principal amount.

      In connection with the acquisition of certain assets of the Retech
division by M4, MMT issued a total of 352,361 shares of its Common Stock to LMC
on April 30, 1996, and December 18, 1996. These shares were acquired by Lockheed
Environmental Systems & Technologies Co. ("LESAT"), an indirect wholly-owned
subsidiary of LMC, as consideration for the sale of certain assets of Retech and
were then transferred by LESAT to LMC. The assets purchased by MMT were deemed
to have a value of approximately $11.2 million. The shares were issued in
accordance with the exemption from the registration requirements of the
Securities Act provided in Section 4(2) of the Securities Act.

</TABLE>

Engineering and construction revenue is from services provided to M4 for the
engineering, design and construction of the M4 Technology Center. The increase
in 1996 over 1995 is a result of billings to M4 during the peak period of
construction and start-up of the M4 Technology Center. Overall, the Company
expects engineering and construction revenue to decline until it enters into
definitive contracts to construct commercial CEP systems for customers that will
be financially responsible, in whole or in part, for the construction of such
systems. In March 1997, the Company and LMC entered into a Letter of Intent to
restructure their relationship currently embodied in M4. Although the Company
may earn revenue in the future pursuant to the proposed new agreements with LMC,
the Company will earn limited additional revenue from the operations of M4 in
1997. Additionally, there is uncertainty as to the amounts and timing of
revenue, if any, that may be earned by the Company in the future under the
proposed new agreements with LMC.

R&D and consulting revenue decreased in 1996 from 1995 due to a reduction in
billings under a cost sharing contract with the United States Department of
Energy (the "DOE"). During 1996, the Company recorded $8 million in revenue for
the reimbursement of R&D costs incurred under the cost sharing contract with the
DOE compared to approximately $13.2 million for 1995. The decrease is a result
of the Company reaching the funded contract value during the third quarter of
1996 and not entering into any arrangements providing for additional funding
from the DOE. The Company expects to continue with research and development
projects, some of which will be funded by third parties and some of which will
be funded from the Company's working capital. The Company anticipates that the
amount of both internally and externally funded research and development will
decrease over the next year.

Technology transfer and success fees increased in 1996 over 1995 due to $5
million of revenue recognized for the sale of a license to M4 for the Japanese
chemical weapons market. During 1996, the Company recognized the remaining $4
million of the original $14 million license fee from M4. This license fee was
being recognized over a two year period that began in August 1994. Also during
1996, the Company recognized $4 million of plant start-up fees from M4. Under
the terms of the M4 limited partnership agreement, the Company was entitled to a
fee of $2 million upon the start-up of each of the first three CEP plants
developed by M4. As of June 30, 1996, the Company had earned each of these three
success fees. Part of the Company's strategy is to license its technology under
arrangements which provide for up-front technology transfer fees, ongoing
tolling fees, license fees or royalties and the Company expects such revenues 
to increase in future periods.

As commercial operations commence at the Company's facilities in Oak Ridge,
Tennessee and Bay City, Texas, the Company expects to generate revenue from
processing and recycling wastes. The Company expects that revenue from plant
operations will be a significant portion of its total revenue in future periods.
During 1996, however, the Company did not receive any revenue from plant
operations. The existence and timing of revenues related to the Company's
commercial operations will depend on a


                                       21
<PAGE>   23


number of factors, including the ability of the Company and its affiliates to
successfully market, permit and build CEP systems on a timely and economic basis
for their target markets, customer acceptance of the technology, and competition
from other companies in the Company's target markets, and no assurances can be
made in this regard.

During 1996, revenue from M4 and DOE accounted for approximately 87% and 13% of
revenue, respectively. The Company anticipates that during 1997 it will earn
limited revenue from the operations of M4. In addition, other than the NICE(3)
grant described in Item 1 above, the Company does not anticipate receiving
research and development funding from the DOE in 1997.

Certain billings by the Company to M4 for engineering and construction,
research and development and consulting services were disputed by M4 and were
not paid by M4. The Company has investigated the circumstances of these
disputes and has determined that the Company's quarterly results of operations
should be restated for the periods ended June 30, 1996 and September 30, 1996.
Revenue of $2.593 million has been reversed in the quarter ended June 30, 1996
because of a dispute regarding the obligation underlying billings in that
amount for that quarter. Revenue of $481,000 has been reversed and a charge to
bad debt expense in the amount of $1.484 million has been recorded in the
quarter ended September 30, 1996 to reflect the doubtful collection, because of
an additional dispute arising prior to the close of the Company's third quarter
accounts, of billings for $1.965 million for the third and prior quarters. The
Company is not pursuing collection of these disputed amounts.  The Company
intends to amend its prior filings on Form 10-Q for the quarters ended June 30,
1996 and September 30, 1996 to reflect these adjustments. In the opinion of
management, all adjustments necessary to revise the quarterly financial
statements have been recorded. Following is a summary of the unaudited
quarterly results of operations for these quarters:

Cost of revenue for 1996 increased to $50.5 from $34.9 million for 1995. The
increase is primarily attributable to an increase in engineering and
construction activities in connection with the development of CEP systems for M4
and the deferral of income related to intercompany profit on the sale of assets
to M4. The Company expects cost of revenue to increase in future periods as
commercial operations commence at its facilities in Oak Ridge, Tennessee and Bay
City, Texas.

Research and development expenses increased to $26.2 million in 1996 from $11.0
million in 1995. The increase reflects an increase in costs associated with the
continued development of CEP and internally funded CEP demonstrations. The
Company expects that R&D costs will decrease in the next year as efforts become
more concentrated on commercial operations. SG&A expenses for 1996 increased to
$18.7 million from $2.9 million in 1995. The increase reflects the hiring of
additional personnel, the expansion of corporate infrastructure and a lower
absorption of SG&A expenses into cost of revenue due to a reduction in cost
reimbursement contracts. The Company is making efforts to decrease SG&A expenses
in future periods. The classification of expenses between cost of revenue, R&D
and SG&A will depend in part 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 and
recorded an equity loss of $31.6 million in 1996 compared to equity income of
$834,000 in 1995. Under the M4 limited partnership agreement, the Company and
LMC share equally in M4's revenues and other income and all expenses are
allocated to LMC until the capital accounts of the Company and LMC are equal.
Thereafter, as long as the capital accounts of the Company and LMC are equal,
the Company and LMC share the profits and losses of M4 equally. During 1995, the
Company's and LMC's capital accounts were not equal and the Company recorded its
share of revenues and other income from M4 without recognizing any expenses from
M4. This resulted in the Company having equity income from M4 in 1995. In the
fourth quarter of 1996, the Company's and LMC's capital accounts became equal
and the Company began to share in the recognition of expenses from M4. Because
of substantial losses at M4 in the fourth quarter of 1996, the Company recorded
$40.9 million in expenses from M4, resulting in a net equity loss from its
investment in M4 of $31.6 million in 1996. A substantial portion of the losses
at M4 are the result of impairment charges totaling approximately $60.9 million
primarily relating to the M4 Technology Center. The Company expects to continue
to incur equity losses from M4 until the ongoing restructuring is completed,
which is expected during the second quarter of 1997.

Interest income for 1996 increased to $8.8 million from $5.6 million in 1995.
The increase is due to interest earned on the net proceeds from the issuance of
convertible debt in May 1996. The Company expects interest income to decline in
the coming year as cash and short-term investments are used to fund initial
commercial operations and continued investment activities, including
expenditures for fixed assets. Interest expense for 1996 increased to $6.5
million from $1.5 million in 1995. The increase is due to interest on the
convertible debt issued in May 1996. Interest expense is expected to increase in
1997 due to a full year of interest on the convertible debt issued in May 1996
and other potential debt financing. Inflation is not expected to have a material
effect on future results of operations.

The Company's results of operations have varied significantly in the past and
may continue to vary significantly in the future. The Company's results of
operations in the past have been dependent largely on revenue from M4 and DOE
and the Company's future profitability is dependent upon its ability to


                                       22
<PAGE>   24

commercialize successfully its CEP technology and to find alternative sources of
revenue. There can be no assurance that the Company will generate sufficient
revenue to achieve profitability.

In February 1997, Financial Accounting Standards No. 128 "Earnings Per Share"
("FAS 128") was issued by the Financial Accounting Standards Board. FAS 128
specifies modifications to the calculation of earnings per share from that
currently used by the Company. Under FAS 128, "basic earnings per share" will be
calculated based upon the weighted average number of common shares actually
outstanding, and "diluted earnings per share" will be calculated based upon the
weighted average number of common shares outstanding and other potential common
shares (stock options, warrants and convertible debt) if they are dilutive. FAS
128 is effective for the Company's fourth quarter of 1997 and will be adopted at
that time. Had the Company determined earnings per share in accordance with FAS
128, basic earnings (loss) per share and diluted earnings (loss) per share for
1996, 1995 and 1994 would not have been materially different from the net income
(loss) per share reported by the Company.

In April 1997, the Company's Board of Directors appointed a committee of three
outside directors to review matters concerning the Company's financial
statements for the year ended December 31, 1996 and the allegations in the
securities class actions described in Item 3 above. The committee has completed
its review of matters affecting the presentation of the Company's financial
statements, including the restatement discussed in Note 17 to the financial
statements.

Years Ended December 31, 1995 and 1994

      Revenue was approximately $44.2 million for 1995 compared with $14.4
million for 1994. The increase is primarily attributable to an increase in
engineering and construction activities in connection with the development of
CEP systems for M4, an increase in license fees from M4 and an increase in
customer-funded activities under TDPs. The increase in 1995 TDP revenue over
1994 is a result of revenue earned under a cost-sharing contract with the U.S.
government.

      During 1995, revenue from M4 and the DOE accounted for approximately 69%
and 30% of revenue, respectively.

      Cost of revenue was approximately $34.9 million for 1995 compared with
$11.1 million for 1994. The increase is primarily attributable to an increase in
engineering and construction activities in connection with the development of
CEP systems for M4 and an increase in costs related to cost-sharing contracts
with the U.S. government.

      Research and development expenses decreased to $11.0 million for 1995 from
$14.4 million for 1994. The decrease is a result of increased customer funding
resulting in an increase in research and development expenses being included in
cost of revenue. Selling, general and administrative expenses decreased to $2.9
million for 1995 from $7.1 million for 1994. The decrease is a result of
increased customer funding resulting in an increase in selling, general and
administrative expenses being included in cost of revenue.

      Interest income increased to $5.6 million in 1995 from $4.4 million in
1995, reflecting a full year of interest earned on the net proceeds from debt
financings in 1994. Interest expense increased to $1.5 million for 1995 from $.7
million for 1994, reflecting a full year of interest expense on a $21 million
tax-exempt bond financing received during 1994. Equity income from affiliate
increased to $.8 million in 1995 from $0 in 1994 reflecting the Company's share
of revenue and other income earned by M4. Inflation is not expected to have a 
material effect on future results of operations.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1996, the Company had cash, cash equivalents and short-term
investments totaling $129.1 million compared to $86.3 million at December 31,
1995. The increase was primarily a result of the net proceeds from the issuance
of the Company's 5 -1/2% Convertible Subordinated Notes Due 2006. The increase
was offset by cash used in operations and for the acquisition of fixed assets.
During 1997, 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 expects that its total
capital expenditures for 1997 will be approximately $83 million.

During December 1996, MMT Tennessee signed a series of agreements to become the
full owner of the Q-CEP facility it had jointly owned with SEG in Oak Ridge,
Tennessee and to acquire certain assets used for handling and processing
radioactive "wet waste." SEG was a wholly-owned subsidiary of Westinghouse
Electric Corporation ("Westinghouse"). The Q-CEP facility is designed to process
radioactive ion exchange resins from nuclear power plants. Pursuant to those
agreements, MMT Tennessee acquired SEG's interest in the Q-CEP facility and
certain assets of SEG and Westinghouse used in the "wet waste" business. These
assets include contracts, equipment, services and personnel for processing
radioactive waste streams at the Q-CEP facility. The purchase price for these
assets was $31 million in cash, which was based on the parties' mutual agreement
as to the fair market value of the assets being acquired. In connection with the
asset purchase, MMT Tennessee obtained a non-compete agreement with SEG and
Westinghouse which was valued based upon its estimated economic benefit to MMT
Tennessee and is being amortized on a straight-line basis over the 5 year life
of the agreement. The excess cost over the net assets acquired is being
amortized on a straight-line basis over a period of ten years.

In March 1997, the Company and LMC announced that they had executed a letter of
intent to restructure their relationship with respect to commercialization of
CEP for the government waste market. The objective of the restructuring is to
enable MMT and LMC to access target markets more efficiently by eliminating many
of the organizational redundancies associated with the current M4 structure. LMC
and MMT believe that the contemplated restructuring also will enable them to
better leverage LMC's expertise in systems integration and MMT's ability to
provide its CEP technology to target markets. After the completion of the
restructuring, LMC and MMT each would be free to pursue projects formerly
governed by the existing joint venture agreements, subject to the requirements
established by the proposed new arrangements. The letter of intent contemplates
five principal changes in the companies' relationship: (1) LMC would have the

exclusive right to lead and pursue contracts for the Hanford radioactive tanked
waste cleanup project described above, and MMT would provide directly to LMC
certain construction and development services with respect to CEP, (2) the
Company and LMC would form a new limited liability company to be their exclusive
vehicle to deliver processing services to customers in the chemical
demilitarization market worldwide, (3) MMT would have the exclusive right to
lead and pursue worldwide opportunities for processing DUF(6), (4) the Company
would become the sole owner of M4, which will continue to own and operate its
primary remaining asset, the M4 Technology Center, and (5) the Retech division
of M4, which provides plasma arc technology, would be transferred to LMC.
In connection with the proposed replacement of M4 by the Company on the Hanford
team, the Company would deliver a pilot-scale, demonstration CEP plant to LMC
in 1997 for a fixed price of $5 million. In addition, if the LMC team is
awarded a contract under Phase 1B of the Hanford cleanup program and CEP is
used in the Phase 1B performance, LMC would pay the Company a fee of $15
million and order a CEP production plant meeting agreed upon criteria at a
price to be negotiated. $5 million of this fee would be payable on award of the
contract and the remaining $10 million would be payable upon timely delivery
and acceptance of the CEP production plant. The Company also would be entitled
to an on-going royalty of 3.5% of all revenues generated from the processing of
waste in equipment supplied by the Company under the Hanford contract.

The limited liability company to be formed by the Company and LMC would have
worldwide rights to commercialize CEP for the chemical weapons demilitarization
market. The limited liability company would be owned 50/50 by LMC and the
Company. The Company would be entitled to success fees of up to an aggregate of
$25 million in connection with the successful deployment of CEP systems to
process chemical weapons. The limited liability company would have an initial
term of five years.

As sole owner of M4, the Company would be responsible for the future operations
of the M4 Technology Center, and would be entitled to all future revenues from
such operations. Under the terms of the letter of intent, the $38 million
aggregate principal amount of bonds issued by the Industrial Development Board
of Oak Ridge relating to the M4 Technology Center would remain outstanding,
LMC's guarantee of these bonds would remain in place, and each of LMC and the
Company would be jointly responsible for the principal, interest and other costs
relating to these bonds.

In addition to the changes described above, the Company and LMC have agreed in
the letter of intent that the Company would have the exclusive right to lead and
pursue worldwide opportunities for processing DUF6. LMC would have the right to
participate in this market on a case-by-case basis, subject to mutual agreement
of the parties, and would agree not to pursue this market for five years except
jointly with the Company. 

LMC and the Company also would establish a strategic alliance committee,
comprising three 


                                       24
<PAGE>   26


representatives from each company, to review and monitor the relationships
created by the restructuring and to evaluate new market opportunities within the
DOE and DoD markets.

In connection with the proposed restructuring, LMC would forgive $15 million
aggregate principal amount and all accrued interest under its line of credit
with M4, and the Company would contribute outstanding accounts receivable of
$14.6 million to M4's capital. LMC and the Company will generally share equally
in substantially all of the costs of the restructuring.

As of December 31, 1996, M4 had not earned any revenues related to the Hanford
radioactive tanked waste cleanup project, nor had M4 earned any revenues from
the processing of chemical weapons or DUF6. As of December 31, 1996, M4 had
earned limited revenues from testing and development work performed at the M4
Technology Center and from testing and development work related to the chemical
demilitarization and DUF6 markets. The Retech division of M4 has been the major
source of revenue for M4 since its contribution to M4 in April 1996.

The restructuring described above is based on the terms set forth in a
non-binding letter of intent between the Company and LMC. Completion of the
restructuring is dependent upon a number of factors, including the negotiation
of definitive agreements and the approval of the Boards of Directors of the
Company and LMC. There can be no assurances that the Company and LMC will
successfully consummate the transactions described in the letter of intent.

On January 29, 1997, MMT Tennessee acquired certain low-level radioactive waste
processing assets of VECTRA, a spent nuclear fuel and radioactive waste services
company located in San Ramon, California. MMT Tennessee paid $3.9 million in
cash for the VECTRA waste-handling assets, which include machinery, equipment,
spare parts, intellectual property and customer contracts

The Company is currently constructing the Bay City CEP Facility in Bay City,
Texas. During 1996, the Company spent approximately $12.6 million for the
engineering, construction and permitting of this facility.

As of December 31, 1996, accounts receivable from affiliate (billed and
unbilled, in the aggregate) decreased by approximately $9.1 million from
December 31, 1995 as a result of the reclassification of certain amounts due
from M4 to accumulated losses of affiliate in excess of investment in light of
the proposed treatment of these receivables in connection with the M4
restructuring.

As of December 31, 1996, other assets increased by approximately $5 million
from December 31, 1995 due to costs incurred for issuance of the Company's 5
- -1/2% Convertible Subordinated Notes Due 2006. As of December 31, 1996, prepaid
expenses increased by approximately $4.0 million from December 31, 1995 due to
increases in prepayments to suppliers, accrued interest receivable and spare
parts. Restricted cash decreased by approximately $4.8 million from 1995 to
1996 due to expenditures of funds reserved for qualified spending relating to a
tax-exempt bond financing for the Fall River Facility The Company's investment
in M4 decreased by approximately $5.9 million from December 31, 1995, resulting
in accumulated losses of affiliate in excess of investment of approximately
$5.0 million, primarily due to the recognition of the Company's share of M4's
expenses, including the effect of a reduction in the carrying value of M4's
long-lived assets.

As of December 31, 1996, deferred revenue from affiliate decreased by
approximately $4 million from December 31, 1995 due the recognition of
technology transfer fees from M4 as revenue in 1996.

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, at the option of the holder,
into shares of the Company's common stock at an initial conversion price of
$38.75 per share. Beginning in May 1999, the Notes become redeemable at the
option of the Company at an initial redemption price of 102.75% of the
principal amount plus any accrued interest. Upon a change of control (as
defined in the Indenture relating to the Notes) or in the event the Company's
common stock is neither listed on a U.S. national securities exchange nor
approved for trading on an established automated over-the-counter U.S. trading
market, each holder of the Notes will have the right to require the Company to
repurchase all or a portion of such holder's Notes at price equal to 100% of
the principal amount plus any accrued interest. The Notes are subordinated in
right of payment to the Company's other existing debt.

In 1994, the Company completed a tax-exempt bond financing in connection with
the Fall River Facility. Pursuant to the financing, the Company entered into a
loan agreement with the Massachusetts Industrial Finance Agency, which issued
$21 million aggregate principal amount of Solid Waste Disposal Facility 


                                       25
<PAGE>   27


Revenue Bonds. The bonds are payable in annual sinking fund installments
beginning in 1998 and ending in 2014 and bear interest at 8.25% per annum
payable semi-annually.

During 1996, the Company earned revenue from M4 relating to services provided
for the engineering and construction of CEP systems and from technology transfer
and success fees. For revenue amounts that are capitalized by M4, the portion of
the related gross profit that is allocable to the Company's ownership interest
in M4 has been deferred, and will be recognized over the period that the related
assets are depreciated by M4. As of December 31, 1996, the related deferred
income increased by $4,435,000 from December 31, 1995 due to billings under
license agreements and construction contracts with M4.

In October 1996, the Board of Directors authorized the Company to repurchase up
to 2,000,000 shares of its common stock. Under this authorization, 40,000 shares
were repurchased by the Company in 1996 for $483,000, and 70,400 shares were
repurchased by the Company in 1997 for $769,000. The Company does not anticipate
repurchasing additional shares in the foreseeable future.

In March 1996, the Company entered into a new lease for the Company's corporate
headquarters. In September 1996, the Company entered into a new lease for
additional space in the same office park as the Company's corporate
headquarters. Each of these leases is for seven years, and future minimum lease
payments of approximately $22.8 million in the aggregate are due on a monthly
basis throughout the seven-year term. The Company does not currently intend to
occupy the second building and is in the process of negotiating subleases for
such space. The Company has accrued $1.3 million for anticipated losses relating
to this lease net of expected sub-lease income.

The Company incurred a substantial net loss for the quarter ended March 31,
1997. The Company's current business plan indicates that the Company will
require additional financing to be used for the completion of its planned
capital expenditures through the end of 1997, including the completion of the
Bay City CEP Facility, and to continue its research, development and other
efforts necessary to commercialize its CEP technology. Accordingly, the Company
intends to raise additional financing during 1997, and has retained several
investment banking firms to assist it in these efforts. These sources of
financing could include a tax-exempt bond financing for MMT Tennessee, which
owns and operates the Q-CEP facility in Oak Ridge, Tennessee and the wet waste
assets acquired from SEG and VECTRA. If the Company does not obtain additional
financing during 1997, it would have a materially adverse effect on the
Company's operations. 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.

The Company has provided a full valuation allowance for deferred tax assets
because the realization of the future benefits from these deferred tax assets
cannot be reasonably assured. The amount of the deferred tax assets considered
realizable is subject to change based on estimates of taxable income during
future periods. If the Company achieves sustained profitability, these deferred
tax assets would be available to offset future income taxes, subject to
potential limitations relating to ownership changes.

FORWARD-LOOKING STATEMENTS AND RISK FACTORS

      Certain statements contained in this Form 10-K regarding future events or
the future financial performance of the Company are "forward-looking statements"
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. These forward-looking statements include
statements concerning the Company's growth strategies, anticipated trends in the
Company's business, receipt of research and development funding, anticipated
capital expenditures, anticipated revenues from license fees and commercial
operations, continued operations and start-up of operations at the Company's and
M4's CEP facilities, construction and operation of the Bay City CEP Facility,
expected sales of CEP systems by the Company and its partners, regulatory
acceptance of the 


                                       26
<PAGE>   28


Company's CEP technology, the Company's plans to obtain additional financing,
and expectations regarding the future performance of the Company's relationship
with LMC. These forward-looking statements are based largely on the Company's
expectations and are subject to a number of risks and uncertainties, many of
which are beyond the Company's control. Accordingly, actual results could differ
materially from those contemplated by these forward-looking statements. Among
the risks and uncertainties which could affect actual results are:

      Customer Acceptance of CEP - CEP is a new and developing technology for
which there is no established market. The Company may be unable to sell CEP
systems if potential customers do not view CEP as an economically and
environmentally acceptable means of disposing of wastes and by-products.

      Development Risk - The Company has limited experience developing and
constructing commercial CEP plants. In addition, the Company's "first of a kind"
CEP plants have required larger capital expenditures and a longer period to
develop and construct than originally anticipated by the Company. If the Company
is not able to develop and construct CEP plants, particularly "second of a kind"
plants, on time and under budget, this would have a material adverse effect on
the Company's ability to successfully sell CEP plants to customers and to obtain
financing for the development and construction of CEP plants.

      Lack of Sustained Commercial Operations - The Company has limited
experience operating commercial CEP plants. There can be no assurance that the
Company will be able to operate CEP systems on a sustained basis in
commercial-scale use, that such systems can be operated profitably, or that such
systems will successfully process feedstocks and recover commercially usable or
saleable materials.

      Compliance with Regulatory Requirements - The Company and its customers
and potential customers must operate in compliance with federal, state and local
environmental laws and regulations. Failure to obtain required permits or
failure of CEP to meet environmental standards would have a material adverse
affect on the Company's ability to sell, site and operate CEP plants. In
addition, the stringency and level of enforcement of environmental laws and
regulations will have a material effect on demand for the Company's technology.

      Obtaining Required Funding - The Company will require substantial funds to
construct the initial commercial CEP systems that it anticipates it will own and
operate, and to continue its development activities. The Company's future
capital requirements could vary significantly and will depend on certain
factors, many of which are not within the Company's control, including
customers' decisions to finance, own and operate their CEP systems; the terms of
any collaborative arrangements entered into by the Company; the progress of the
Company's development of CEP; the nature and timing of permits required for CEP
systems; and the availability and terms of alternative sources of financing.
Failure to obtain necessary financing could have a materially adverse impact on
the Company's ability to own and operate certain initial CEP facilities and to
continue its development activities.

      Dependence on Disposal Facilities - Some materials produced using CEP may
have little to no commercial value, and may be considered wastes. Such waste may
be classified as a hazardous or low-level radioactive waste (and may need to be
handled as such) under current United States environmental regulations. In
addition, such waste may need to be disposed of at specially permitted disposal
facilities. In order to utilize such facilities, any waste produced by CEP must
meet the acceptance criteria of the particular facility. Fees for disposal of
wastes at such facilities, and the methods for calculating such fees, are
subject to change. The Company's ability to operate its CEP systems profitably
may be adversely affected by increases in such fees or changes in the methods of
calculating such fees. The Company expects that the volume of residual waste
streams produced from the processing of radioactive wastes with Q-CEP will be
greater than those produced from other applications of CEP.

      Significant Customers - The Company has historically been dependent on two
customers, M4 and the DOE, for a substantial portion of its revenues. The
Company does not expect to be receiving substantial revenues from M4 or the
Department of Energy in 1997. The Company's future profitability is 


                                       27
<PAGE>   29


dependent upon, among other things, its ability to find alternative sources of
revenue. There can be no assurance that the Company will generate sufficient
revenue to achieve profitability.

      Operating History - The Company's quarterly revenues and operating results
have varied significantly in the past and may continue to vary significantly in
the future as a result of the factors listed above. In addition, because the
purchase of a CEP plant involves a substantial capital commitment, the Company's
sales cycle can be lengthy and subject to risks and uncertainties over which the
Company has little or no control. These include budgetary constraints,
regulatory requirements, changes in technology, and competition. Variations in
the timing of recognition of particular revenues due to changes in project scope
or timing may adversely and disproportionately affect the Company's operating
results. The Company's future profitability is dependent upon, among other
things, its ability to successfully commercialize its CEP technology. There can
be no assurance that the Company will generate sufficient revenue to achieve
continued profitability.

      Competition - The Company's competitors, many of which have substantially
greater financial resources than the Company, may develop technologies superior
to those of the Company. To the extent these competitors offer comparable
services or products at lower prices or of higher quality, or more
cost-effective waste disposal alternatives, the Company's ability to compete
effectively could be adversely affected.

      Additional factors which may cause actual results to differ are described
in Exhibit 99.1 to this Form 10-K, as well as the Company's other filings with
the Securities and Exchange Commission and are incorporated herein by reference.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

      The financial statements and schedules data listed in Item 14 are filed as
part of this report on pages F-1 through F-42.

      The filing of this report and the release of the Consolidated Financial
Statements for the year ended December 31, 1996 were delayed by the events
described in Item 9 hereof and by the need to complete assessments of the
recoverability of the long-lived assets of the Company and M4 in accordance with
the requirements of Financial Accounting Standards No. 121.

      Also, in April 1997, the Company's Board of Directors appointed a
committee of three outside directors to review matters concerning the Company's
financial statements for the year ended December 31, 1996 and the allegations in
the securities class actions described in Item 3 above. The committee has
completed its review of matters affecting the presentation of the Company's
financial statements, including the restatement discussed in Note 17 to the
financial statements.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE.

      On March 27, 1997, M4 engaged Price Waterhouse LLP ("Price Waterhouse") to
audit M4's financial statements for the fiscal year ended December 31, 1996.
Price Waterhouse was engaged by M4 after Coopers & Lybrand L.L.P., the previous
accountants for M4, resigned as M4's accountants on March 6, 1997. Coopers &
Lybrand advised M4 that it had resigned as M4's accountants mainly because Price
Waterhouse proposed to refer to Coopers & Lybrand's report on M4's financial
statements in Price Waterhouse's audit of the Company's financial statements,
and Coopers & Lybrand did not want to consent to such association. In its
capacity as the Company's independent accountants, Price Waterhouse has not
expressed reliance on any audit report of Coopers & Lybrand relating to M4.
Coopers & Lybrand's audit reports for M4 for the period from inception (August
1994) through the date of resignation did not contain any adverse opinions or
disclaimer of opinions or qualifications or modifications as to uncertainty,
audit scope or accounting principles, and there were no disagreements or
reportable events (within the meaning of Item 304 of Regulation S-K) between M4
and Coopers &

                                       28
<PAGE>   30


Lybrand during such period. Prior to the engagement of Price Waterhouse, M4 had
not consulted with Price Waterhouse regarding the application of accounting
principles to a specified transaction or the type of audit opinion that might be
rendered on M4's financial statements. The Company has consulted with Price
Waterhouse, in Price Waterhouse's capacity as the Company's independent
accountants, on various occasions with respect to transactions between the
Company and M4.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      In October 1996, the Company and Maurice F. Strong, a director of the
Company, entered into a Consulting Agreement pursuant to which Mr. Strong will
provide advice on the design and implementation of international sales and
marketing strategy for the Company's products and technology, and will assist in
negotiating transactions with international customers. Pursuant to the
Consulting Agreement, the Company granted to Mr. Strong a non-qualified option
to purchase 10,000 shares of Common Stock at an exercise price of $34.75 per
share, which was the closing price of the Common Stock on the date of grant. The
stock option vests in five annual installments of 2,000 shares, provided that
Mr. Strong is then being retained by the Company under the Consulting Agreement.
In addition, the Company will pay Mr. Strong a retainer of $5,000 per month. The
Agreement has a one year term, and renews automatically for successive one year
terms unless terminated by either party.

The Company and John T. Preston, a director of the Company, are parties to a
Consulting Agreement pursuant to which Mr. Preston will provide advice on
technology implementation, business planning, and other projects assigned from
time to time by senior management of the Company. Pursuant to the Consulting
Agreement, the Company pays Mr. Preston a retainer of $3,334 per month. The
Agreement has a one year term, and renews automatically for successive one year
terms unless terminated by either party.
      
      Peter A. Lewis, a director of the Company, is a limited partner of
Lazard Freres & Co. ("Lazard") and has served as a limited managing director of
Lazard since 1995. During 1996, Lazard was a lead underwriter of an offering of
$143,750,000 of convertible notes issued by the Company.

      In August 1996, December 1996 and January 1997, the Company loaned G. Earl
McConchie, an officer of the Company, a total of $60,000, bearing interest at
8.25% per year, payable on the earlier of (a) the sale of Mr. McConchie's
previous house, or (b) 30 days after Mr. McConchie's termination of employment
with the Company.

      In January 1997, the Company loaned Eugene Berman, an officer of the 
Company, $60,000, bearing interest at 8.25% per year, payable in December 1997.

      The Company may make loans to affiliates in the future, subject to
approval by the Company's Board of Directors.

      During 1996, the Company granted Mr. McConchie 40,000 shares of restricted
Common Stock as part of his employment agreement. 30,000 of these shares will be
restricted for a period of five years. Restrictions on the remaining 10,000
shares will lapse at a rate of 25% per quarter beginning March 31, 1997.

      During 1996, the Company granted B. J. Garner, an officer of the Company, 
10,000 shares of restricted Common Stock as part of his employment agreement.
The restrictions on these shares will lapse at a rate of 25% per quarter
beginning March 31, 1997. In addition, the Company provided Mr. Garner with a
$100,000 signing bonus as an incentive to join the Company and adjust to a
higher cost of living in Massachusetts. Should Mr. Garner terminate his
employment with the Company during his first year, he would be required to
refund the entire amount of the bonus.

      In 1990, the Company purchased the rights to certain patents related to
CEP from Christopher J. Nagel, an officer and a director of the Company, and a
member of the Company's Technology Advisory Board for $1,500,000. Each of Dr.
Nagel and the Technology Advisory Board Member are entitled to one-half of the
aggregate purchase price. The purchase price is payable in annual payments of
25% of the Company's pretax profits, as defined in the purchase agreement;
however, the Company may elect to accelerate the payments. As of December 31, 
1996, a total of $57,055 had been paid to Dr. Nagel pursuant to this agreement.

                                    Article 3

                Capitalization and Funding of the JV; Accounting

      3.1.  Capitalization of the JV. At the time of formation of the JV, the

shall be made in cash. The Partners shall mutually determine how the balance of
the JV's initial funding is to be paid. All such funding shall be contributed by
each Partner in proportion to its initial equity investment.

losses (determined in accordance with generally accepted accounting principles
as applied in Japan) in the aggregate. Notwithstanding the foregoing, if the
JV sustains more than $14,500,000 in losses, any Partner shall have the right
to terminate the business relationship established by this Agreement and the
Related Agreements in accordance with Section 8.5.

for losses shall be based on each Partner's equity interest in the JV.

      3.5   Accounting; Books and Records. The JV's fiscal year shall end on 
such date as the Partners shall mutually agree. The JV shall retain a mutually
acceptable accounting firm to audit the JV's financial statements for each
fiscal year and to prepare the JV's income tax returns. The books and records of
the JV shall be maintained, and the financial statements of the JV shall be
prepared, in accordance with generally accepted accounting principles as in
effect in Japan, consistently applied. The Board of Directors shall appoint a
Partner to be responsible for keeping and maintaining the JV's books and
records.

            Partner shall notify the other Partners in writing of the persons
            designated by it to serve on the Board of Directors and any
            replacement for such person promptly following such designation
            or replacement.  Each Partner hereby agrees to votes its shares
            of the JV, and to cause the directors of the JV designated by
            such Partner to cast their votes, so as to appoint as directors
            and President-Director the individuals nominated by the other
            Partners in accordance with this Section 4.1.

      (b)   One of the Nichimen/NKP Directors shall be nominated jointly by
            Nichimen and NKP to serve as the Representative Director, subject
            to the approval of MMT.  The Representative Director also shall
            be designated as the President of the JV (the "President-Director").
            The President-Director shall preside at all meetings of the Board 
            of Directors and shall have such other duties and responsibilities 
            as are assigned from time to time by the Board of Directors.

      (a)   The Board of Directors shall have the specific authority delegated
            to it pursuant to this Agreement and the Related Agreements.

      (b)   Without limiting the general duties and authority of the Board of
            Directors as set forth in this Article 4, the Board of Directors
            shall have responsibility for the following matters related to the
            business of the JV:

            (i)   the appointment and evaluation of the performance of any
                  Nichimen, NKP, MMT or other personnel assigned or hired to
                  participate in the management of the JV's operations;

            (ii)  the evaluation of the performance of the President-Director;

                  budgets;

            (iv)  issuance of sublicenses for CEP Plants;

            (v)   incurrence of indebtedness;

            (vi)  establishment of sales and marketing policies;

            (vii) approval of any sales representative agreement,
                  manufacturing agreement, or sublicense agreement;

            (viii)approval of capital increases;

            (ix)  election or removal of independent public accountants;

            (x)   approval of the distribution of profits or the payment of
                  losses;

            (xi)  approval of any proposals required to be submitted to the
                  shareholders;

            (xii) approval of employment policies and personnel regulations;
                  and

            (xiii)such other duties agreed to from time to time by the
                  Partners.

            The Board of Directors shall also review the Business Plan at least
            annually, and revise it as appropriate to reflect the business
            conditions and prospects for the JV.

      4.3.  Meetings. The Board of Directors will meet as often as the members
deem necessary, presently contemplated to be four times per year. Meetings may
be conducted in 


                                       10
<PAGE>   11

person or by telephone or in any other manner agreed to by the Board of
Directors. Any Partner may call a meeting of the Board of Directors upon at
least three (3) weeks' prior notice. No notice of a meeting shall be necessary
when all members of the Board of Directors are present. The presence of at least
both MMT Directors and both Nichimen/NKP Directors shall constitute a quorum.
All actions of the Board of Directors shall require the unanimous consent of all
Directors present and participating in a meeting. Meetings of the Board of
Directors may be attended by other representatives of the Partners and other
persons related to the JV all as agreed to from time to time by the Board of
Directors. The Board of Directors will set up procedures relating to the
recording of minutes of its meetings. To the extent permitted by applicable law,
actions of the Board of Directors may also be taken without a meeting by
unanimous written consent of the Board of Directors.

      4.4.  JV Personnel.

      (a)   It is anticipated that the JV will not have any employees but will
            rely on personnel from Nichimen, NKP and MMT to manage its
            operations. Such personnel shall be designated by the applicable
            Partner, subject to approval by the Board of Directors. Unless
            otherwise agreed by the Board of Directors, all such personnel shall
            be paid by the Partner which designated them.

      (b)   Notwithstanding paragraph (a), until such time as the JV has sold at
            least one CEP Plant, the JV may, if necessary, retain not more than
            one employee for administrative and related functions. Such
            employee, if any, will be nominated by the President-Director,
            subject to approval by the Board of Directors. The terms of such
            employee's employment, including compensation, will be determined by
            the Board of Directors. After the JV has sold at least one CEP
            Plant, the Board of Directors shall decide whether or not to hire
            additional employees based on the actual business needs of the JV.

      4.5.  President-Director. The President-Director shall have the duties and
responsibilities described in Section 4.6. The President-Director may be removed
from office only with the unanimous agreement of the Board of Directors (other
than the President-Director), except that if either the MMT Directors or the
Nichimen/NKP Directors have objected to the Board of Directors on at least three
separate occasions about the President-Director's performance, providing
information about the grounds for such objections in reasonable detail, then
upon the request of the objecting party the Board of Directors shall remove the
President-Director. Upon the retirement or removal of the President-Director,
Nichimen and NKP shall nominate a new President-Director, subject to the
approval of MMT.

      4.6.  Duties of President-Director. Except as provided in Section 4.2
hereof and the Articles of Incorporation, the President-Director shall be
responsible for the day-to-day management, operations, direction and
administration of the JV, implementing the policies established by the Board of
Directors, and shall have such other duties and responsibilities 


                                       11
<PAGE>   12

related to the JV as the Board of Directors shall from time to time direct. The
President-Director shall be responsible for advising the Board of Directors on
the status of the JV on a regular basis or more frequently as requested by the
Board of Directors. The President-Director also shall be responsible for hiring
such personnel, if any, as the President-Director and the Board of Directors
deem necessary and appropriate. Unless otherwise agreed by the Board of
Directors, all such personnel shall be subject to the approval of the Board of
Directors.

                                    Article 5

 Operations of the JV; Sales and Marketing of CEP Plants; Certain Commitments

      5.1. Operations of the JV. In commercializing CEP pursuant to this
Agreement, the Partners will consider all appropriate business structures to
maximize sales of CEP Plants. Based on the Partners' analysis of the existing
conditions in the Market, the Partners anticipate that the JV's operations
initially will be conducted as described in the Initial Business Paradigm set
forth in Section 5.2.

      5.2.  Initial Business Paradigm.

      (a)   Pursuant to a sublicense from the JV, sales of CEP Plants will be
            made by Nichimen and NKP (and potentially MMT or third party sales
            representatives appointed pursuant to Section 5.5) directly to
            owners of municipal waste incinerators in the Exclusive Market and
            under certain circumstances in the Non-Exclusive Market ("End
            Users"). It is anticipated that Nichimen and NKP would enter into
            long-term contracts with such End Users which would provide for the
            sale, importation, transportation, installation, start-up, testing,
            operation and maintenance of CEP Plants by Nichimen and NKP for the
            benefit of the End Users. The price for the CEP Plant and other
            goods and services to be provided to the End Users will be
            negotiated by Nichimen and NKP as prime contractors directly with
            the End Users. An itemized list of prices for the CEP Plant and such
            goods and services will be provided to the Board of Directors.

      (b)   Nichimen and NKP will utilize, subject to MMT's approval, a form of
            agreement to be used for such CEP Plant sales and services. Such
            agreement will, at a minimum, include provisions requiring the End
            User of the CEP Plant to (i) protect the MMT and the JV's
            Confidential Information and Intellectual Property, (ii) only use
            the CEP Plant for the processing of the Market Feedstocks expressly
            specified in the CEP Plant sales agreement, (iii) purchase specified
            critical spare parts for the CEP Plant only from MMT, and (iv)
            indemnify the JV and the Partners from any damage or injury caused
            by the End User's improper use or operation of the CEP Plant.
            Changes to the standard agreement may be made to the extent required
            as a result of negotiations with the End User, provided that the
            Board of Directors will have


                                       12
<PAGE>   13

            the right to review all CEP Plant contracts and to approve any
            material changes to the standard agreement.

      (c)   MMT will design, engineer and construct all CEP Plants and spares to
            be sold by Nichimen, NKP and any third party sales representatives
            on behalf of the JV. The price to the JV for each CEP Plant shall be
            determined solely by MMT based on the capacity of the CEP Plant and
            any special customer requirements. All prices quoted by MMT shall be
            free on truck "ex works". Nichimen, as sole importer for the JV,
            shall purchase the CEP Plants and spares from MMT and shall be
            responsible for the transportation of such CEP Plants and spares    
            from MMT's factory to Japan. For this service, Nichimen shall
            receive the following trading commissions: (i)   *      of the
            price to the JV of the Initial CEP Plant; (ii)        * of the
            price to the JV of CEP Plants, including any initial spares; and
            (III) * of the price to the JV of any replacement parts or spares.

      (d)   The JV will purchase the CEP Plants and spares from Nichimen and
            then resell them to Nichimen or NKP, as applicable, for resale to
            the End User on the terms described in paragraph (a). NKP will act
            as the prime contractor for the installation, operation and
            maintenance of CEP Plants on behalf of the End User unless (i)
            otherwise requested by the End User for business reasons, or (ii)
            the purchaser of the CEP Plant will act as the prime contractor for
            the End Use. If the End User requests that NKP not serve as the
            prime contractor, Nichimen will propose another prime contractor to
            the Board of Directors. The Board of Directors shall have the right
            to approve or disapprove any such other prime contractor.

      (e)   Nichimen and NKP acknowledge and agree that as prime contractors
            they shall be responsible for negotiating, consummating and
            financing sales of CEP Plants to End Users. All such sales shall be
            without recourse to the JV and shall not impose any financial
            obligations on the JV. To the extent possible, Nichimen and NKP will
            keep the terms of transactions between Nichimen, NKP, MMT and the JV
            consistent with respect to the purchase and sale of CEP Plants and
            spares.

      5.3.  Other Business Paradigms. The Partners agree that one of their 
            shared goals is to minimize the involvement of the JV from the
            actual delivery of CEP Plants in order to minimize the transaction
            and overhead costs of the JV to the maximum extent possible.
            However, to the extent that the use of business paradigms designed
            to implement this goal result in the incurrence of extraordinary tax
            liabilities by the JV, the Partners will continue to use the Initial
            Business Paradigm or attempt to structure other operational
            paradigms that meet this goal.

      5.4.  Sales and Marketing. Each of the Partners will provide marketing
            support at their own expense to the JV. This support shall include
            making available to the JV all


                                       13



*Confidential treatment has been requested for this portion of Exhibit 10.46.

commercial opportunities in the Market known to the Partners. The Partners agree
to cooperate in their provision of marketing support to the JV in order to make
such marketing as successful as possible. Except as provided in Section 5.2, the
JV shall be required to obtain the consent of the Board of Directors with
respect to the customer, material contract terms, license arrangements and
related matters prior to the completion of any sale of a CEP Plant by the JV. In
order to coordinate and maximize the Partners' respective sales and marketing
efforts, representatives of the Partners with responsibility for sales and
marketing in the Market shall meet from time to time, but no less often than
four times per year, to discuss marketing strategy and the steps each Partner is
taking to promote CEP Plants in the Market. Such meetings may take place at or
in conjunction with meetings of the Board of Directors. Each Partner shall
provide to the other Partners copies of all marketing materials and shall keep
the other Partners informed of any regulatory changes that may affect the sale
or use of CEP Plants in the Market.

      5.5.  Sales Representatives. In addition to direct sales to customers, the
JV may enter into sales representative agreements with any of the Partners and
any other entity which services the Market. Such sales representatives will be
paid commissions based on the sales price of CEP Plants which they sell. The
Partners will agree upon a form of Sales Representative Agreement (including
commissions) to be used by the JV. Consistent with the Initial Business
Paradigm, it is not presently anticipated that the JV will enter into Sales
Representative Agreements with Nichimen or NKP.

      5.6.  Fall River Demonstration Programs. Nichimen and NKP acknowledge that
MMT is constructing a demonstration CEP Plant in Fall River, Massachusetts which
will be used for, among other things, demonstration programs for Market
Feedstocks and surrogate Market Feedstocks. The Partners agree that the data
from such demonstration programs may be useful for the JV in its efforts to
commercialize CEP in the Market. The Partners also agree that the demonstration
CEP plant in Fall River may be a valuable marketing tool for the sales
activities of the JV and the Partners. Accordingly, the Partners agree that if
potential customers of the JV desire to have MMT perform demonstration programs
at the Fall River Facility, such demonstration programs will be paid for by the
JV. The payment terms for any such demonstration programs will be agreed on a
case-by-case basis by the JV and MMT. In connection with such demonstration
programs, MMT agrees to permit potential customers of the JV to visit the Fall
River facility and observe the operations of the demonstration CEP Plant. All
such visits shall be at reasonable times and shall require at least two (2)
weeks' notice to MMT. All potential customers will be required to sign
non-disclosure agreements whereby they agree not to disclose any of the
information learned from their observation of the demonstration CEP Plant or any
data or other information provided by MMT.

      5.7.  Start-Up of Initial CEP Plant. In order to assist the JV in the
start-up and operation of the Initial CEP Plant, NKP will provide the services
of two engineers and five technicians at the JV's expense. Such engineers and
operators will be dedicated solely to the start-up of the Initial CEP Plant.

                          Exclusivity; Non-Competition

      7.1.  Exclusive Market Obligation of MMT. 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) own or operate any CEP
Plant that processes MSW Incinerator Ash in Japan or sell or license any CEP
Plant pursuant to sale or license terms which permit such CEP Plant to process
MSW Incinerator Ash in Japan.

      7.2.  Non-Competition Obligation of Nichimen and NKP.

      (a) In consideration of the grant of an exclusive license to the JV
          pursuant to the License Agreement, each of Nichimen and NKP 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) promote, market, sell, license, acquire from a third
          party, operate, finance or otherwise commercialize any technology for
          the Treatment or Recycling of Market Feedstocks. Any activity from
          which Nichimen and NKP and their respective Affiliates are restricted
          pursuant to this paragraph (a) is referred to herein as a "Competing
          Activity". In addition, each of Nichimen and NKP agrees that its
          obligations under this paragraph (a) shall survive the termination of
          the business relationship contemplated by this Agreement for

     (c)  The restrictions contained in paragraph (a) above shall not prevent
          the ownership by Nichimen or NKP or their respective Affiliates of any
          Voting Securities or other voting equity interest in a business that
          engages in a Competing Activity, if such Voting Securities or other
          equity interest represents less than 5% of all the voting power of the
          stock or equity in a business that engages in such Competing Activity,
          and if such stock or equity interest is listed on a national

          considered a violation of this Section 7.2. The Board of Directors
          shall at the request of Nichimen, NKP or MMT meet to discuss any
          current or proposed activities of Nichimen, NKP or their respective
          Affiliates to determine whether such activities are prohibited by this
          Section 7.2.

<PAGE>   18

            such termination, (iii) any provision of a Related Agreement which
            by its terms states that it shall survive such a termination shall
            survive and (iv) such termination shall not effect any Partner's
            rights with respect to any breach or non-performance by another
            Partner prior to such termination.

      (b)   In the event of any termination of this Agreement pursuant to
            Section 7.2(b) or any one of Sections 8.1 to 8.6, the Board of
            Directors will be responsible for winding up the JV.  The Board
            of Directors shall wind up the JV in an orderly and prudent
            manner consistent with the JV's then-existing obligations
            (including with respect to developed CEP Plants), with the goals
            of fulfilling the JV's contractual obligations, protecting
            customer goodwill, limiting any residual liability to the
            Partners and effecting a division of assets consistent with the
            Partners' ownership interests in the JV.  It is anticipated that

                  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

                  otherwise) acquire beneficial ownership of any Voting
                  Securities of Nichimen or NKP or any of their respective
                  Subsidiaries, any securities convertible into or exchangeable

                  Securities of Nichimen or NKP or any of their respective
                  Subsidiaries, without the consent of Nichimen or NKP, as
                  applicable, if the effect of such acquisition would be to
                  increase the percentage of Voting Securities of Nichimen, NKP
                  or such Subsidiary then beneficially owned directly or
                  indirectly by MMT and its Affiliates to more than 4.9% of the
                  Voting Securities of Nichimen, NKP or such Subsidiary then

                           Uncontrollable Circumstances, gives the other parties
                           oral notice, followed by written confirmation,
                           describing the particulars of the occurrence;

                  (ii)     the suspension of performance is of no greater scope

                  (iv)     the nonperforming party uses its best efforts to
                           promptly remedy its inability to perform.

                  complying with any conditions that it must comply with, under

the parties. If any such changes will cause the price of the Project to exceed
the Fixed Price, such amendment shall reflect the new Fixed Price for the
Project, as so changed.

5.      Performance Tests

        5.1    During 1997, MMT shall perform a performance test (the "U.S.

(the "U.S. Test Period") to determine whether the MX-1 meets the following
criteria (the "U.S. Performance Criteria"):




                                        *





        5.2    During the U.S. Test Period, MMT shall collect samples and
measurements to determine whether throughput, product specifications and utility
consumption figures are being met. If the performance of the MX-1 as determined
by the average of these measurements collected during the U.S. Test Period meets
the specifications set forth in the U.S. Performance Criteria, the U.S.
Performance Test shall be deemed satisfactorily completed, and MMT shall
thereupon give written notice to that effect to the JV, Nichimen and NKP. If the
JV agrees that the MX-1 has met the U.S. Performance Test, the JV shall execute
and return to MMT one copy of an acceptance letter to be provided by MMT. If the
JV does not agree that the MX-1 has met the U.S. Performance Test, the JV shall
notify MMT of such disagreement within ten (10) days from receipt of MMT's
notice, stating the specific reasons therefor. The JV shall be deemed to have
accepted the results of the U.S. Performance Test if the JV has failed to
respond to MMT's notice within the foregoing ten-day period.

        5.3    If the performance of the MX-1 during the U.S. Performance Test 
does not meet the U.S. Performance Criteria, MMT, at its own expense, shall make
such changes in the MX-1 as it deems necessary to make the MX-1 meet the U.S.
Performance Criteria. Thereafter, the U.S. Performance Test shall be repeated as
required until such time as the performance of the MX-1 has met the U.S.
Performance Criteria.

        5.4    As soon as practicable after the Project has been installed at 
the Project Site, the JV, with the assistance of NKP, shall perform a
performance test (the "Japan Performance Test") in Japan over a seven (7) day
period (the "Japan Test Period") to determine whether the Project meets the
following criteria (the "Japan Performance Criteria"):

        5.5    During the Japan Test Period, the JV shall collect samples and
measurements to determine whether throughput, product specifications and utility
consumption figures are being met. If the performance of the Project as
determined by the average of these measurements collected during the Japan Test
Period meets the specifications set forth in the Japan Performance Criteria, the
Japan Performance Test shall be deemed satisfactorily completed, and the JV
shall thereupon give written notice to that effect to MMT, Nichimen and NKP.

        5.6    If the performance of the Project during the Japan Performance
Test does not meet the Japan Performance Criteria as a result of defective
workmanship or materials in the Project or the components thereof or faults in
the design and process of the Project or the components thereof, MMT, at its
expense shall make such changes in the Project as it deems necessary to make
the Project meet the Japan Performance Criteria. If the performance of the
Project during the Japan Performance Test does not meet the Japan Performance
Criteria for any other reason, including but not limited to defective
workmanship or materials in the assembly and installation of the Project or the
components thereof, the JV, at its own expense, shall make such changes in the
Project as it deems necessary to make the Project meet the Japan Performance
Criteria. Thereafter, the Japan Performance Test shall be repeated as required
until such time as the performance of the Project has met the Japan Performance
Criteria.


6.      Equipment Warranty

        6.1    MMT warrants that the Project shall be free from defects in
workmanship and material under normal use and service for a period of one (1)
year following delivery of the Project to the Project Site (the "Warranty
Period"). The JV shall be entitled to 100% of the manufacturer's warranty on
all purchased components (i.e., not of MMT's manufacture) to the maximum extent
possible. *
        
        6.2    The warranty set forth in Section 6.1 shall not apply to (i) 
items designed to be consumed or subject to normal wear while undergoing normal
operation, including but not limited to refractories and tuyeres, or (ii) any
equipment which, after delivery, has been subject to abuse, accident,
alterations by anyone other than persons authorized by MMT, improper storage or
installation, misuse in its applications, improper maintenance or failure to
observe the operating instructions.

        6.3    MMT's obligation under the warranty set forth in Section 6.1 
shall be limited solely to repair or replacement of defective products. Before
MMT undertakes any obligation to

remedy defects, the JV must give written notice of its claim within fifteen (15)
days after discovery within the warranty period. The decision on the remedy to
any claim will rest solely with MMT. In no event shall MMT's liability for any
and all losses and damages to the JV resulting from defective equipment exceed
the cost of repair and/or replacement of the defective parts. MMT shall use
attempt to cause the manufacturer of any repaired or replaced equipment to
provide an extended warranty for such equipment.

shall confine MMT's Agents to that portion of the Project Site or the JV's
premises where the MMT Services are to be performed.

        9.2    The JV shall ensure that MMT's agents are provided with all
safeguards and warnings necessary to protect such persons against any conditions
on the Project Site or the JV's premises which could be dangerous and to prevent
accidents of any kind whenever MMT Services are being performed. The JV shall
provide MMT's Agents with any and all applicable safety rules, policies and
procedures in effect on the Project Site or the JV's premises.

required to comply fully with all laws, ordinances, and regulations of the
proper public authorities in connection with the installation and operation of
the Project, and shall operate the Project in accordance with such licenses,
permits, laws, ordinances and regulations.

11.     Indemnity

        11.1    The JV agrees to indemnify, defend and save harmless MMT, its
affiliates, agents and subcontractors, and their respective officers, employees,
or agents (collectively, the "Indemnitees"), from and against all claims,
demands, actions, damages, actions, causes of action, losses, costs, expenses or
penalties (including costs of defense, settlement and reasonable attorney's
fees), including but not limited to death or bodily injury to any person,

orders (collectively, "Losses"), which arise out of or in connection with (a)
the ownership, use or operation of the Project by the JV; (b) any breach by the
JV of any term or provision of this Agreement; and (c) the JV's failure to
comply with any applicable permit, license, law, rule, regulation, ordinance or
order governing the operation of the Project. In connection with any demands,
claims or any other legal proceedings covered by this Section 11.1, the JV shall
have the right to control the defense thereof, provided that MMT retains the
right to be represented, at its sole option, by attorneys of its own selection.
The exercise of this right to select its own attorneys will in no way detract
from or release the JV from its obligation to indemnify and hold MMT harmless
hereunder.

        11.2    Notwithstanding any provision of Section 11.1 to the contrary,
the JV shall not be required to provide indemnification to the extent that any
Loss results from the negligence of any Indemnitee. MMT agrees to indemnify and
save harmless the JV from and against any Loss solely to the extent that such
Loss results from the negligence of MMT.

such insurance companies, which shall provide that the insurance company agrees
to notify MMT in writing ten (10) days in advance of any material change in, or
cancellation of, any of the insurance described in such certificates. The

limit in any way the liability or obligations assumed by MMT elsewhere in this
Agreement.

from time to time, and any other agreement between any of the JV, Nichimen, NKP
or MMT relating to the JV which specifies that it is a Related Agreement for
purposes of this Agreement.

         "Requesting Party" has the meaning set forth in Section 3.1.

         "Settlement Information" has the meaning set forth in Section 3.5.1.

         2. Covered Disputes. The dispute resolution procedures provided for in
this Agreement shall apply to all disputes which may arise among any of the
parties hereto with regard to any aspect of the interpretation or performance of
any of the Related Agreements, or any aspect of or circumstance relating to the
negotiations, preparation, execution of any of the Related Agreements or any
aspect of the relationship contemplated by the JV Agreement. Such disputes
subject to this Agreement are referred to herein as "Covered Disputes."

         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 the JV, Nichimen, NKP 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 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,
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.

<PAGE>   49


         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 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.

              3.5.3. 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 among Nichimen, NKP 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 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.

         6.   Exclusive Remedy For Breach. Except as expressly provided in any
of the Related Agreements, in the event of any breach of this Agreement or the
Related Agreements by the JV, Nichimen, NKP or MMT, the non-breaching party or
parties shall be entitled to seek relief with respect to such breach pursuant
to the procedures provided in this Agreement. However, the non-breaching party
or parties shall not be entitled to terminate this Agreement or any of the
Related Agreements or to suspend or withhold the performance of any of its or
their obligations under this Agreement and the Related Agreements as a result
of such breach.
        
         7.   Miscellaneous.

         7.1. Entire Agreement. This Agreement together with the Related
Agreements constitutes the entire agreement between the parties with respect to
the subject matter hereof and thereof and merges and replaces all prior
negotiations, discussions, offers, representations, warranties, covenants, and
agreements of the parties in respect of such subject matter.

         7.2. Amendment; Waiver. This Agreement may be amended only by a written
instrument signed by all parties. The failure of any party to insist on one or
more occasions upon strict performance by the other party of any its obligations
hereunder shall not constitute a waiver, release, or amendment of such party's
right to insist upon strict performance of such obligation on future occasions.

                           (ii) above.

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

                  (i)      a non-transferable royalty-bearing non-exclusive
                           license under the Licensed Property (other than the
                           Licensed Trademarks) to sell, own, lease, rent,
                           operate, install and maintain CEP Plants located
                           anywhere in Japan that process Industrial Incinerator

                           license to sublicense the Licensed Property, subject
                           to and in accordance with the requirements of Article
                           7, to Nichimen, NKP and appropriate third parties in
                           order to permit them to sell, own, operate, install
                           and maintain CEP Plants located anywhere in Japan
                           that process Industrial Incinerator Ash; and

                  (iii)    a non-transferable royalty-bearing non-exclusive
                           license to use the Licensed Trademarks in connection

                  The licenses granted to the JV pursuant to this paragraph (b)
                  shall be applicable only where sales of CEP Plants are made to
                  owners or operators of facilities 


                                       6

                  which process both MSW Incinerator Ash and Industrial
                  Incinerator Ash, provided that such facilities process
                  predominantly MSW Incinerator Ash.

         (c)      In the event that the JV desires to sell a CEP Plant to an
                  owner or operator of a facility which does not process
                  predominantly MSW Incinerator Ash, the JV shall provide MMT
                  with a description of the Feedstocks which would be processed
                  by such CEP Plant and such other information as MMT may
                  request in order to permit it to quote a price and the terms
                  of sale for such CEP Plant. The JV acknowledges that such
                  price may include additional engineering and design work
                  necessary for MMT to deliver such CEP Plant. MMT shall have
                  the option, on a case-by-case basis, to agree to the sale of
                  any such CEP Plant. To the extent that MMT agrees to sell any
                  such CEP Plant to the JV, the licenses granted to the JV in
                  paragraph (b) shall be applicable to such sale.

         (d)      The licenses granted pursuant to this Section 2.1 shall not
                  permit the JV or its sublicensees to process any Feedstocks at
                  any CEP Plant that are not Market Feedstocks or to sell or
                  operate any CEP Plant except in accordance with the provisions
                  of this Agreement and the Related Agreements.

         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 have been or are in the future developed
with or acquired from any third party, are or 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 is or may in the
future become a party. In the event that any future 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 JV. If MMT is unable to so obtain such
rights, it will cooperate to make available to the JV such rights as the third
party is willing to grant to or for the JV.

                                    Article 3

                        Exclusivity; Retention of Rights

         3.1.     Exclusive Market Obligation of MMT. 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) own or operate any CEP
Plant that processes MSW Incinerator Ash in Japan or sell or license any CEP
Plant pursuant to sale or license terms which permit such CEP Plant to process
MSW Incinerator Ash in Japan.

         3.2.     Retention of Rights by MMT. Notwithstanding anything in this
Agreement to the contrary, MMT shall have no obligation to offer the JV any
rights, including but not limited to rights of expansion under Section 3.2,
outside the Exclusive Market, and shall be free to enter into any arrangements
with respect to the Non-Exclusive Market or any markets outside the 


                                       7
<PAGE>   62
Exclusive Market as MMT shall deem appropriate in its sole discretion. If during
any three (3) one-year periods commencing January 1, 1998 the JV does not sell
any CEP Plants pursuant to the non-exclusive licenses granted under Sections
2.1(b) and (c) above, then MMT may terminate such licenses. The purchase of a
CEP Plant shall be evidenced by the execution of binding contracts between
Nichimen, NKP or other contractor of the JV and a customer for the purchase of
such CEP Plant, on the one hand, and between the JV and MMT for the design and
construction of such CEP Plant, on the other hand.

                  The JV shall permit MMT and its authorized Advisors to

                  JV in order to verify the accuracy of the Fee Certificate.

                  calculated based on the average of the exchange rate quoted in
                  the Wall Street Journal over the period from the last day of

                  Certificate or the amount or timing of any payment made to
                  MMT, then MMT and the JV shall resolve such dispute pursuant

         (b)      With respect to any disclosure by the JV to any of its
                  officers or employees permitted pursuant to Section 5.2(b)(i),
                  the JV shall cause each of its officers and employees to sign
                  Employee Non-Disclosure Agreements.

         (c)      With respect to any disclosure by the JV or MMT to any of its
                  Advisors pursuant to Sections 5.2(b)(ii) or to any customers
                  or sublicensees pursuant to Section 5.2(b)(iii) or (iv), the
                  Board of Directors will institute procedures designed to
                  maintain the confidentiality of Confidential Information while
                  facilitating the business activities contemplated by this
                  Agreement and the Related Agreements. These procedures shall
                  include the preparation of standard forms of confidentiality
                  agreements to be used by the parties in connection with such
                  disclosures.

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

         5.6.     Quality Control. The JV shall provide to MMT a reasonable
opportunity to inspect the CEP Plants using the Licensed Property and the
services provided by the JV under the Licensed Trademarks (collectively, the "JV
Services"), upon MMT's request from time to time in order to enable MMT to
maintain an appropriately high level of quality commensurate with the valuable
goodwill associated with the Trademarks (the "Quality Standard"). If MMT
reasonably determines that the applicable CEP Plants or the JV Services being
performed by the JV do not meet the Quality Standard, MMT shall provide the JV
with written notice (the "Failure Notice") of such failure, specifying the
particular aspect of the applicable CEP Plants or the JV Services which MMT
claims does not meet the Quality Standard and the particular failure, together
with any supporting documentation of such failure. If the JV shall not have met
such Quality Standard for such JV Services and does not (i) take appropriate
action to diligently commence to cure such failure within thirty (30) days after
receipt of the Failure Notice and (ii) cure such failure by causing such JV
Services to meet such Quality Standard and provide documentation of such cure
reasonably acceptable to MMT within sixty (60) days after the receipt of the
Failure Notice, MMT may pursue any available remedies pursuant to the Dispute
Resolution Agreement. The JV may recommend to MMT any actions which the JV
reasonably believes should be taken to meet the Quality Standard and, if MMT
agrees with any such recommendation, the JV and MMT shall work together to
determine the appropriate actions which should be taken to meet the Quality
Standard.

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

                  requested by MMT and at MMT's expense, but without further
                  consideration, execute all papers and documents and perform
                  all other acts necessary or appropriate, in the discretion of
                  MMT, to evidence or further document MMT's ownership of all
                  Intellectual Property and Improvements.

         (b)      In the event MMT is unable after reasonable effort, for any
                  reason whatsoever, to secure the signature of the JV on
                  disclosure or other documents in connection with the
                  assignment of rights in Intellectual Property and Improvements
                  as provided in Section 6.1, the JV hereby irrevocably
                  designates and appoints MMT and its duly authorized officers
                  and agents as its attorney-in-fact, to act for and in the JV's
                  behalf and stead to execute and file any such documentation,
                  and to do all other lawfully permitted acts to prepare
                  documentation for and further the prosecution and issuance of
                  any rights in Intellectual Property or Improvements with the
                  same legal force and effect as if executed by the JV.

permit 


                                       12
<PAGE>   67
them to sell, import, transport, operate and maintain CEP Plants to service the
Market as described in Section 5.2 of the JV Agreement. Such sublicenses with
Nichimen and NKP will be in the form of Annex E hereto.

         7.2. Form of Sublicensing Agreements. As part of the comprehensive
sublicensing program referred to in Section 7.1, MMT and the JV shall develop
various forms of sublicense agreements to be used by the JV. With respect to any
sublicense agreement to be used by the JV, the Board of Directors shall have the
right to approve the sublicensee and the final terms of the sublicense
agreement.

specifications) in CEP Plant sales agreements which are standard for the
relevant industry with respect to CEP Plants and services provided to the JV.
The JV will pass such warranties along to the customer pursuant to an equipment
sale agreement between the JV and the customer. It is anticipated that such
warranties, as well as any indemnification to be provided by MMT and the
limitations of MMT's liability in connection with sales of CEP Plants to the JV,
will be determined on a case-by-case basis based on industry standards and the
requirements of the End User.

         8.2. Component Sales. As part of the ongoing quality control program of
MMT, MMT shall sell to the JV and any customers of the JV, and the JV and such
customers shall be required to purchase, specified CEP system components,

on or arising out of the use of the Licensed Property by either MMT or the JV,
such party shall promptly give written notice thereof to the other parties.

         9.2. Infringements of Licensed Property. In the event of any
Infringement of the Licensed Property or any claim that any Licensed Property,
or any equipment, material or process based on or utilizing Licensed Property,
infringes any proprietary right of any third Person (an "MMT Infringement
Claim"), then, subject to Section 9.4 below, MMT shall take such action as MMT
deems appropriate to address such Infringement or MMT Infringement Claim, as the
case may be. The JV, Nichimen and NKP shall cooperate as may be requested by MMT
in the prosecution, settlement or compromise of any such Infringement or MMT
Infringement Claim, and agrees to be joined as a party to any legal action or
proceeding commenced by MMT if it is deemed to be necessary or desirable by MMT
for the prosecution of such action or proceeding. If MMT proceeds to bring any
legal action or proceeding pursuant to the procedure provided for in this
Section 9.2, MMT will bear all reasonable costs of such action or proceeding
and, as applicable, will be entitled to receive and retain all proceeds realized
as a result of any settlement thereof or any judgment thereon or will pay any

combination by the JV of any non-infringing Licensed Property, or any
non-infringing equipment, material or process based on or utilizing Licensed
Property, with any Intellectual Property not furnished by MMT, or any claim that
the use by the JV of the Licensed Property, or any equipment, material or
process based on or utilizing Licensed Property, in a manner not contemplated by
this Agreement infringes, misappropriates, violates or dilutes any proprietary
right or property of any third Person (each a "JV Infringement Claim"), then,
subject to Section 9.4 below, the JV shall have the obligation to take all
actions reasonably necessary to oppose or defend such claims and to pay any
judgment or settlement amount awarded or obtained with respect to such JV
Infringement Claim. In the course of opposing or defending any such JV
Infringement Claim, the JV shall consult with MMT, Nichimen and NKP in
connection with all material issues relating to such opposition or defense and
shall consult with MMT, Nichimen and NKP prior to commencing the same and shall
consider any recommendations by MMT, Nichimen and NKP with respect to the
conduct and settlement or compromise thereof and any reasonable alternative
resolutions of the JV Infringement Claim. In the event that the JV does not
undertake to oppose or defend any such action within ninety (90) days after the
JV becomes aware of such JV Infringement Claim, MMT will have the right to
undertake the opposition or defense of such claim in the JV's name. MMT shall
not settle any JV Infringement Claim without the prior written consent of
Nichimen and NKP. If MMT undertakes to oppose or defend any JV Infringement
Claim pursuant to the procedure provided for in this Section 9.3, the JV shall
bear all costs of such action or proceeding and shall pay any judgment or
settlement amount awarded or obtained with respect to such JV Infringement
Claim. In the event that MMT does not undertake to oppose or defend any such
action within 180 days after the JV becomes aware of such JV Infringement Claim,
Nichimen and NKP shall have the right to undertake the opposition or defense of
such claim in the JV's name on the same basis as is applicable to MMT pursuant
to the preceding sentences.

elements of both an MMT Infringement Claim and a JV Infringement Claim, MMT and
the JV 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 JV Infringement Claim.
