Item 2 - Acquisition or Disposition of Assets

On January 29, 1997 VECTRA Technologies, Inc. (the "Seller" or the "Company")
sold its waste services operations ("VECTRA Waste Business" or  the "Waste
Business") to MMT of Tennessee Inc. ("MMT" or the "Buyer").  The form of the
transaction was a sale of assets pursuant to an Asset Purchase Agreement among
the Company and the Buyer, dated January 29, 1997 (the "Agreement").

The purchase price for the sale of the Waste Business was $3,900,000 (the
"Purchase Price").  The assets purchased by the Buyer included substantially all
of the Waste Business' assets with the exception of cash, accounts receivable
and work in process inventory.  The liabilities assumed by the Buyer generally
included  the personal property leases, other waste contracts and waste customer
contracts and certain responsibilities with respect to the equipment,
transportable vitrification system and the RVR 7200.

Item 5 - Other Events

With the sale of the Engineering Business in August 1996 and of the Waste 
Business in January 1997, the Company's current business consists solely of 
the handling, transportation and storage of high-level radioactive wastes. 
Because of the Company's reduced size and product lines, the Company's 
current and future business operations are subject to a number of risks and 
uncertainties. In evaluating the risks of an investment and any 
forward-looking information provided by the Company, investors should be 
aware that the Company's actual results could differ materially from the 
results discussed in any forward-looking statements because of, among other 
factors generally affecting companies in the nuclear industry, the following: 
(a) the Company is subject to a variety of stringent regulatory agency 
requirements in the U.S. and foreign countries that affect the manufacturing 
of its products, and the failure to comply with such requirements may result 
in litigation, liability or government-ordered shutdowns; (b) the Company's 
need for working capital and annual and quarterly operating results may vary 
considerably from period to period as a result of a number of factors, 
including milestone requirements under customer contracts, and cancellations 
or delays by customers; (c) a substantial portion of the Company's future 
sales will be to fewer than 10 customers, the loss of any of which would 
adversely affect the Company's business, results of operations and financial 
condition; (d) some of the Company's principal competitors have been active 
in the nuclear service industry for many years and may have extensive 
relationships with customers in the Company's current area of operations and 
may have strong financial resources.

Item 7. Financial Statements and Exhibits

(b)  Pro forma financial information

The Company will file as an amendment to this Form 8-K by April 5,1997, the
following pro forma financial statements, for which filing herewith is
impracticable:

    Pro forma balance sheet of the Company as of December 31,1996 and pro forma
    statement of income for the year ended December 31, 1996.

from all governmental authorities as are necessary or desirable for the conduct
of the VECTRA Waste Business or in connection with the ownership or use of the
Acquired Waste Business Assets, except for licenses, permits or other
authorizations where the failure of the Seller to have and maintain any or all
of such licenses, permits and authorizations would not have a Material Adverse
Effect.  Except as expressly designated on SCHEDULE 5.4, none of the Permits are

of all of the documents, reports, site assessments, data, communications and
other materials listed on SCHEDULE 5.10(c) hereto.

          (d)  For purposes of this Section 5.10, the term "to the Seller's
knowledge" or similar qualifiers shall mean (i) any information set forth in any

Seller in the ordinary course of business and are in good condition and repair
for their present use in the VECTRA Waste Business.  The Vitrification Equipment

transferred as part of the Acquired Waste Business Assets on an "as is, where
is" basis.

     5.12.  INSURANCE.  SCHEDULE 5.12 hereto lists all policies of fire,
liability, workmen's compensation, life, property and casualty and other
insurance owned or held by the Seller or maintained by the Seller in respect to
the Acquired Waste Business Assets or the VECTRA Waste Business.  All such
policies (a) are in full force and effect and (b) are sufficient for compliance
in all material respects by the Seller with all requirements of law and all
agreements to which the Seller is a party.  Such insurance policies will remain
in full force and effect through the Closing Date after which the Seller may at
its option terminate such policies.  The Seller is not in default with respect
to its obligations under any of such insurance policies and has not received any
notification of cancellation of any such insurance policies.

     5.13.  CONTRACTS.  Except for those contracts listed on SCHEDULE 5.13 and
except for those instances in which the Seller, in the ordinary course of
business, has agreed to perform services after the Closing Date in anticipation
of receiving a purchase order for such services in amount not to exceed $10,000,
the Assumed Waste Contracts are the only contracts or other agreements of the
Seller (whether entered into directly by the Seller or as successor by merger to
VWS or VSI) currently in effect and relating to the VECTRA Waste Business.  The
Seller has delivered to the Buyer true, correct and complete copies of all
Assumed Waste Contracts, together with all modifications and supplements
thereto.  The Assumed Waste Contracts are valid and binding obligations of the
parties thereto, and have not been terminated, and to the Seller's knowledge the
Seller is not in breach of any of the provisions of any Assumed Waste Contract,
nor, to the knowledge of the Seller, is any other party to any such contract in
breach thereof, nor to the Seller's knowledge does any event or condition exist
which with notice or the passage of time or both would constitute a default
thereunder, except for any breaches or non-compliance that individually or in
the aggregate
<PAGE>

                                      -13-


would not have a Material Adverse Effect.  The Seller has performed in all
material respects all obligations required to be performed by it to date under
each Assumed Waste Contract.  Subject to obtaining any necessary consents by the
other party or parties to any Assumed Waste Contract (the requirement of any
such consent being reflected on SCHEDULE 5.13), no Assumed Waste Contract
includes any provision the effect of which may be to enlarge or accelerate any
obligations of the Buyer to be assumed thereunder or give additional rights to
any other party thereto or will in any other way be affected by, or terminate or
lapse by reason of, the transactions contemplated by this Agreement.

SCHEDULE 5.14 hereto, the Seller has no employment agreement, written or oral,
with any currently active employee of the VECTRA Waste Business, including any
agreement to provide any bonus or benefit to any such employee of the VECTRA
Waste Business.  Except as set forth on SCHEDULE 5.14, since January 1, 1996,
none of the Seller, VWS or VSI has made any pension, bonus or other payment,
other than base salary, per diem and expenses, or become obligated to make any
such payment, to any employee of the Seller in the VECTRA Waste Business.
Except as set forth on SCHEDULE 5.14, the Seller has no outstanding loans or
advances to any employee in the VECTRA Waste Business.  Since January 1, 1996 no

Internal Revenue Service ("IRS") determination letters and any governmental
advisory opinions or rulings.  With respect to the VECTRA Technologies Savings
and Retirement Plan No. 001 (the "SELLER'S 401(k) PLAN"), to the Seller's
knowledge nothing has occurred since the date of the IRS determination letter
relating to the Seller's 401(k) Plan which would adversely affect such favorable
determination.

     5.16.  LABOR RELATIONS.  Except as set forth on SCHEDULE 5.16, to the
Seller's knowledge, with respect to the VECTRA Waste Business the Seller is in
full compliance in all material respects with all federal and state laws

     5.17.  TRADEMARKS, PATENTS, ETC.  (a)  SCHEDULE 1.1(i) hereto sets forth a
complete and accurate list of (i) all existing patents, trademarks, trade names
and copyrights owned by and registered in the name of any of the Seller, VWS or
VSI and used or proposed to be used by the Seller in connection with the VECTRA

and other agreements relating thereto, and (ii) except for commercially
available "shrink wrap" software licenses, all licenses and other agreements
regarding the Intangibles pursuant to which any of the Seller, VWS or VSI has
licensed or authorized for use by others any of the Intangibles or pursuant to
which any of the Intangibles has been licensed or authorized for use to any of

<PAGE>

                                      -15-


such agreement and any successors and assigns, including any successors to the
business of such entity through merger, sale of all or substantially all of the
stock, assets or other interest in or of such party.  Except as set forth on
SCHEDULE 5.17(a), all of the Seller's rights under such agreements are freely
assignable.  To the extent they constitute Intangibles for purposes of this
Agreement, true and complete copies of all such agreements listed on
SCHEDULE 1.1(i), and any amendments thereto, have been provided to the Buyer.
All of the Seller's patents, patent applications, trademark registrations,
trademark applications and registered copyrights regarding Intangibles have been
duly registered in, filed in or issued by the United States Patent and Trademark
Office, the United States Register of Copyrights, or the corresponding offices
of other jurisdictions as identified on SCHEDULE 1.1(i), and except as set forth
on SCHEDULE 1.1(i) have been properly maintained and renewed in accordance with
all applicable provisions of law and administrative regulations of the United
States and each such other jurisdiction.  The Seller is not aware of any reason
that would prevent any pending applications to register trademarks, service
marks or copyrights or any pending patent applications regarding Intangibles
transferred hereunder from being granted.

          (b)  Except as set forth on SCHEDULE 5.17(a), the Intangibles
constitute all Intellectual Property required for the ordinary course operation
of the VECTRA Waste Business as currently conducted and, in the case of the
Vitrification Equipment or the Seller's three reverse osmosis systems (the
"RO SYSTEMS"), as proposed to be conducted.  Except to the extent set forth in
SCHEDULE 5.17(b) hereto, the Seller owns or has all required rights to use all
of those Intangibles used or necessary for the ordinary course operation of the
VECTRA Waste Business as presently conducted and, in the case of the
Vitrification Equipment and RO Systems, as proposed to be conducted, and the
consummation of the transactions contemplated hereby will not alter or impair
any such right.  Except as set forth in SCHEDULE 5.17(b), (i) no royalties are
paid or payable by the Seller on or with respect to any of the Intangibles, and
upon the consummation of the transactions contemplated hereby, no additional
royalties shall be payable with respect to such Intangibles, and (ii) each of
the inventions and trade secrets listed in SCHEDULE 5.17(b) hereto have, through
assignment, agreement, operation of law or otherwise, become the sole property
of the Seller.

          (c)  Except as set forth in SCHEDULE 5.17(c) hereto, to the Seller's
knowledge, neither the Seller, nor to the best of the Seller's knowledge, the
other party or parties thereto, is in breach of any license, sublicense or other
agreement relating to Intangibles, except for any breaches that singly or in the
aggregate would not cause any of the Intangibles to no longer be available to
the Seller or otherwise have a Material Adverse Effect.  To the Seller's
knowledge, the Seller, VWS and VSI have complied with all of their obligations
of confidentiality in respect of the Intangibles of others and the Seller knows
of no violation of such obligations of confidentiality as are owed to the
Seller, except for any non-compliance or violations that singly or in the
aggregate would not cause any of the Intangibles to no longer be available to
the Seller or otherwise have a Material Adverse Effect.  The Seller, VWS and VSI
have required all of their employees to execute agreements under which such
employees are required to convey to the Seller ownership of all inventions and
developments conceived or created by them in the course of their
<PAGE>

                                      -16-


employment and to maintain the confidentiality of all of the Seller's non-public
information.  To the Seller's knowledge, the Seller has not made any such
information regarding the VECTRA Waste Business or the Acquired Waste Business
Assets available to any Person other than employees of the Seller except
pursuant to written agreements requiring the recipients to maintain the
confidentiality of such information and appropriately restricting the use
thereof.  To the Seller's knowledge, no employee, agent or consultant of the
Seller is subject to confidentiality restrictions in favor of any third Person
regarding the VECTRA Waste Business or the Acquired Waste Business Assets the
breach of which could subject the Seller to any material liability or which
could adversely affect the Seller's access to any Intangibles previously used by
it in the VECTRA Waste Business.  No claims have been asserted, and to the
Seller's knowledge no claims are threatened, by any Person regarding the
manufacture, use or sale of any of the Intangibles, or challenging or
questioning the validity or effectiveness of any license or agreement relating
to the Intangibles, and to the Seller's knowledge there is no basis for such
claim, except in the case of any of the foregoing for any claims that
individually or in the aggregate will not have a Material Adverse Effect.  The
use of the Intangibles by the Seller in the ordinary course operation of the
VECTRA Waste Business as currently conducted, and in the case of the
Vitrification Equipment and RO Systems, as proposed to be conducted, does not
conflict with or infringe on the rights of any Person, and none of the Seller,
VWS or VSI  has received any claim or written notice from any Person to such
effect, except for any conflicts, infringements or violations that singly or in
the aggregate would cause any material portion of the Intangibles to no longer
be available to the Seller or otherwise have a Material Adverse Effect.  To the
knowledge of the Seller, no third party is infringing, violating or otherwise
using, in an unauthorized manner, any of the Intangibles, except for any
conflicts, infringements or violations that singly or in the aggregate will not
cause any of the Intangibles transferred hereunder to no longer be available to
the Seller or otherwise have a Material Adverse Effect.

of material importance to the VECTRA Waste Business has canceled or otherwise
terminated, or threatened to cancel or otherwise to terminate, its relationship

supplier or customer intends to cancel or otherwise substantially modify its
relationship with the Seller or to decrease materially or limit its services,
supplies or materials to the Seller, or its usage or purchase of the Seller's
services or products, and to the knowledge of the Seller, the communication of

as currently conducted by the Seller and to the Seller's knowledge in the case

obligations of others), which would affect the Buyer or the Acquired Waste
Business Assets other than performance obligations with respect to the Waste
Customer Contracts and Other Waste Contracts that would not be required to be
reflected or reserved against on a balance sheet of the Seller prepared in
accordance with GAAP or in the footnotes thereto.

     5.21.  TAX RETURNS.  Except as set forth on SCHEDULE 5.21, the Seller, VWS
and VSI have filed all tax returns and reports which are required to be filed
with any foreign, federal, state or local governmental authority or agency, and
has paid, or made adequate provision for the payment of, all assessments
received and all taxes which have or may become due under applicable foreign,

     6.4.  GOVERNMENTAL CONSENTS.  Except as set forth in SCHEDULE 6.4 hereto,
no consent, approval or authorization of, or registration, qualification or

                                    ARTICLE 7

                          CERTAIN TRANSITIONAL MATTERS

     7.1. NONASSIGNABLE CONTRACTS.

     (a)  To the extent that any Assumed Waste Contract is not capable of being
transferred by the Seller to the Buyer pursuant to this Agreement without the
consent, approval or waiver of a third person or entity (including a
governmental authority), and such consent is not obtained prior to the Closing,
or if such transfer or attempted transfer would constitute a breach thereof or a
violation of any law, rule or regulation, nothing in this Agreement will
constitute a transfer or an attempted transfer thereof.
<PAGE>

                                      -20-


     (b)  Notwithstanding anything contained in this Agreement to the contrary,
the Seller will not be obligated to transfer to the Buyer any of its rights and
obligations in and to any of the Assumed Waste Contracts  referred to in
paragraph (a) without first having obtained all consents, approvals and waivers
necessary for such transfers.  The Seller shall use its best efforts, and the
Buyer will cooperate with the Seller and use its best efforts, to obtain such
consents, approvals and waivers, to resolve the impracticalities of transfer
referred to in paragraph (a) and to obtain any other consents, approvals and
waivers necessary to transfer to the Buyer any of such Assumed Waste Contracts.
Each of the Buyer and the Seller shall bear its own expenses incurred in
connection with such efforts.

     (c)  In the event that such consents, approvals and waivers referred to in
paragraph (a) are not obtained by the Seller and the Closing occurs, then, in
the case of any Waste Customer Contract unless and until any such Waste Customer
Contract is subcontracted to the Buyer as contemplated below or such Waste
Customer Contract is returned to the Seller as contemplated by paragraph (e)
below, the Seller and the Buyer will each use its best efforts, each at its own
expense, to (i) provide to the Buyer the benefits and burdens of any Assumed
Waste Contract referred to in paragraph (a), (ii) cooperate in any reasonable
and lawful arrangement designed to provide such benefits and burdens to the
Buyer without incurring any obligation to any other person or entity other than
to provide such benefits to the Buyer, including without limitation the
appointment of the Buyer as the agent of the Seller for purposes of such Assumed
Waste Contract and (iii) enforce, at the request of the Buyer for the account of
the Buyer any rights of the Seller arising from any such Assumed Waste Contract
(including without limitation the right to elect to terminate such Assumed Waste
Contract in accordance with the terms thereof upon the advice of the Buyer).
The Seller and the Buyer agree that, with respect to any Waste Customer Contract
of the type referred to above in this paragraph (c), if a consent to assignment
cannot be obtained and a consent to subcontract is required from a third person,
they will solicit such consent. If such a consent to subcontract is obtained
with respect to any such Waste Customer Contract, the Seller and the Buyer will
enter into a Subcontract substantially in the form of EXHIBIT C (a
"SUBCONTRACT"), and thereafter the Buyer will complete the performance of such
Waste Customer Contract pursuant to such Subcontract.  If any such Subcontract
is entered into, then the Seller will hold in trust for the Buyer all future
payments received under the applicable Waste Customer Contract and will as
promptly as practicable and in no event later than three business days remit
such payments to the Buyer.

     (d)  No consent, approval or waiver of a third person or entity (including
a governmental authority) with respect to the transfer of, or any novation with
respect to, any Assumed Waste Contract, shall cause an Excluded Liability to be
deemed for purposes of this Agreement to have become an Assumed Liability or
vice-versa or otherwise affect the respective rights of the Buyer and the Seller
under Article 11.

     (e)  If the Buyer and the Seller are unable to obtain any required consents
to assign or subcontract any particular Waste Customer Contract (with any such
Waste Customer Contract again referred to herein as an "UNASSIGNED CONTRACT"),
and it becomes
<PAGE>

                                      -21-


evident to the Seller and the Buyer that no such consent will be obtained, and
no other mutually satisfactory arrangements are agreed to, then (i) such
Unassigned Contract shall be deemed not to have been transferred to the Buyer,
(ii) the Seller and the Buyer shall treat such Unassigned Contract as if the
Seller and the Buyer had entered into a seconding arrangement with respect to
such Unassigned Contract as of the Closing Date, (iii) the Buyer shall convey to
the Seller any and all assets relating to such Unassigned Contract including,
but not limited to, all accounts receivable and unbilled receivables and cash
relating to such Unassigned Contract and created after the Closing Date, and
(iv) the Seller shall assume all liabilities relating to such Unassigned
Contract.  To implement the retroactive treatment of such Unassigned Contract as
a seconded contract, the Seller and the Buyer will enter into a seconding
agreement.  Such seconding agreement shall be in a mutually acceptable form and
shall be structured similar to the arrangement described in  clauses (i)-(iii)
of the first sentence of paragraph (c) above, with the effect that the Buyer
bears economic responsibility for all profits and losses for such Unassigned
Contract and all liabilities arising after the Closing with respect to the
performance of such Unassigned Contract.

     7.2. GENERAL ASSISTANCE.

          (a)  The Buyer agrees to provide such support (including the
availability of personnel and records) as the Seller may reasonably request to
assist the Seller in (i) providing warranty services on a seconded basis in
connection with any of the Seller's contracts with customers, relating to the
VECTRA Waste Business, that do not constitute one of the Waste Customer
Contracts, (ii) defending any litigation, arbitration or other
dispute-resolution proceeding relating to any casualty, personal injury,
property damage, Equal Employment Opportunity Commission or other claims against
the Seller constituting part of the Excluded Liabilities, (iii) pursuing claims
of the Seller against insurers or other miscellaneous claims, (iv) preparing
invoices with respect to and collecting the Retained Receivables as provided in
Section 7.7 and (v) assisting the Seller in closing the Seller's books for the
VECTRA Waste Business.  The Seller shall continue to direct all such litigation
and shall be responsible for all costs (including legal fees and expenses
incurred in connection therewith).  The Seller agrees to pay the personnel costs
of the Buyer (based on the Reimbursement Rate (as defined in Article 12)) and
out-of-pocket expenses (including fees and expenses of consultants), in all
cases promptly after submissions of invoices in reasonable detail as a monthly
basis.

          (b)  The Seller agrees to provide such support (including the
availability of personnel and records) as the Buyer may reasonably request to
assist the Buyer in (i) defending any litigation, arbitration or other
dispute-resolution proceeding relating to any casualty, personal injury,
property damage, Equal Employment Opportunity Commission or other claims (other
than Excluded Liabilities) or (ii) pursuing claims against insurers or other
miscellaneous claims.  The Buyer shall direct all such litigation and shall be
responsible for all costs (including legal fees and expenses incurred in
connection therewith).  As part of the foregoing support the Seller agrees to
use its best efforts consistent with its current compensation structure to keep
the employees listed on
<PAGE>

                                      -22-


SCHEDULE 7.2(b) hereto available to provide transitional support to the Buyer
for a period of sixty (60) days after the Closing.  The Buyer agrees to pay the
personnel costs of the Seller (based on the Reimbursement Rate) and
out-of-pocket expenses (including fees and expenses of consultants), in all
cases promptly after submissions of invoices in reasonable detail on a monthly
basis.

     7.3. HIRING EMPLOYEES.

          (a)  At the Closing the Buyer will offer employment to the employees
of the Seller listed on SCHEDULE 7.3 hereto.  The employees accepting such offer
are referred to below as the "ASSUMED EMPLOYEES".

          (b)  The Seller shall retain all responsibility (including all
responsibility for severance) for all employees of the Seller other than the
Assumed Employees.  The Buyer shall have all responsibility for severance to any
Assumed Employee.  In addition, the Seller shall retain all responsibility to
its employees (including the Assumed Employees with respect to all periods prior
to the Closing) under the Employee Benefit Plans.  Nothing in this Agreement
shall obligate the Buyer to make any offer of employment to anyone other than an
Assumed Employee or, except as provided in paragraph (c) below, to provide
continued employment to any employee of the Seller, whether or not the subject
of an employment offer from the Buyer, for any specified period of time
following the Closing Date, or to maintain the same terms of employment
(including compensation and benefits) for any specified period of time following
the Closing Date.  The Buyer will offer employment as of the Closing Date only
to the persons listed on SCHEDULE 7.3.

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

          (d)  On the next regularly scheduled pay date after the Closing, the
Seller will pay the Assumed Employees all amounts due under the Employee Benefit
Plans, the Seller's policies and applicable Laws for items that have accrued to
the Closing Date.
<PAGE>

                                      -23-


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

     7.4. UNDISCLOSED CONTRACTS.  If the Buyer learns that the Seller failed
(whether or not inadvertently) to list any customer contract on SCHEDULE 1.1(f)
(list of Waste Customer Contracts), other than any contract the performance of
which has been completed, then the Buyer shall have the option to treat such
contract as a Waste Customer Contract for all purposes under this Agreement.

     7.5. ACCESS TO BOOKS AND RECORDS.

          (a)  The Seller agrees to cooperate with the Buyer and make available
to the Buyer, and permit the Buyer to make copies of, all books and records of
the Seller relating to the VECTRA Waste Business which are not delivered to the
Buyer pursuant to this Agreement (including, but not limited to, correspondence,
memoranda, books of account and the like) and relating to (i) events occurring
prior to the Closing and relating to the VECTRA Waste Business and
(ii) transactions or events occurring subsequent to the Closing which are
related to or arise out of transactions or events occurring prior to the Closing
and relating to the VECTRA Waste Business.

          (b)  The Buyer agrees to cooperate with the Seller and to make
available to the Seller, and permit the Seller to make copies of, such
documents, books, records or information relating to the Acquired Waste Business
Assets or the VECTRA Waste Business prior to the Closing as the Seller may
reasonably require after the Closing in connection with any tax determination,
matter or claim or contractual obligations to third parties, or to defend or
prepare for the defense of any claim against the Seller or to prosecute or
prepare for the prosecution of claims against third parties by the Seller
relating to the conduct by the Seller of the VECTRA Waste Business or in
connection with any governmental investigation of the Seller.

          (c)  The Buyer and the Seller will each direct its employees to render
any assistance which the other party may reasonably request in examining or
utilizing records referred to in this Section 7.5, provided that each party
shall be reimbursed by the other for any out-of-pocket expenses which it may
incur in rendering the services provided for in this Section 7.5.  In addition,
to the extent that any records referred to in this Section 7.5 retained by the
Seller and any records referred to in this Section 7.5 transferred to the Buyer
are located in the same third-party storage facilities, the Buyer and the Seller
shall enter into mutually acceptable arrangements regarding the sharing of
costs, security procedures and similar matters.  In addition, to the extent that
either the Buyer or the Seller concludes at any
<PAGE>

                                      -24-


time more than sixty (60) days after the Closing Date in its reasonable judgment
that its personnel have been devoting significantly more time providing the
services referred to in paragraph (a) or paragraph (b) above than the personnel
of the other party, the Buyer and the Seller will agree on mutually acceptable
reimbursement provisions to reflect such disparity.

          (d)  The Buyer and the Seller each agrees to preserve and protect all
books, records, files and data referred to in Section 1.1(j), paragraph (a)
above or paragraph (b) above for a period of two (2) years after the Closing
Date.  During such period the Buyer and the Seller will not destroy any such
records without giving at least thirty (30) days' notice to the other party.
Upon receipt of such notice, such other party may (i) cause to be delivered to
it the records intended to be destroyed, at such other party's expense or
(ii) notify the first party that such other party will pay the cost of storing
and maintaining such books and records (including any necessary costs of moving
such books and records to a location under control of such other party).

          (e)  The Seller will keep all information referred to in this
Section 7.5 confidential in accordance with Section 10.1.

     7.6. AUDIT RIGHTS.  The Seller and the Buyer agree that, in order to verify
compliance by the other with the various obligations under this Agreement, each
shall have the right at its cost, upon reasonable prior notice, to audit the
relevant records of the other in order to determine whether the other party has
complied with its obligations under this Agreement.

     7.7. COLLECTION OF ACCOUNTS RECEIVABLE.  (a) During the 75-day period
beginning on the Closing Date the Seller will collect all the Retained
Receivables, except that portion to be collected by the Buyer pursuant to
Section 7.17.  The Seller will provide such information relating to such
Retained Receivables and the Seller's collection efforts as the Buyer may
reasonably request from time to time, and will in any event deliver to Buyer, at
least once per month, a reasonably detailed report of collections.  In addition,
the Buyer shall be entitled to review the Seller's proposed invoices relating to
the Retained Receivables to be collected by the Seller prior to mailing.  The
Seller will collect and manage such Retained Receivables on a basis consistent
with the past practice of the VECTRA Waste Business.  The Seller will not
initiate any adversarial action against any account debtor on a Retained
Receivable without first discussing such proposed action with the Buyer and
obtaining the Buyer's consent, which will not be unreasonably withheld or
delayed.  The Buyer will provide reasonable assistance to the Seller in
connection with such collection efforts.  The Seller will compensate the Buyer
for employees used in its billing and collection efforts (based on the
Reimbursement Rate) and reimburse the Buyer for any out-of-pocket costs
(including fees and expenses of consultants).  Any such reimbursement shall be
made promptly by the Seller after receipt of appropriate supporting
documentation.  The Buyer will designate a single representative to act as
liaison with the Seller and to monitor the Seller's collection efforts pursuant
to this Section 7.7.
<PAGE>

                                      -25-


          (b)  At the end of the 75-day period referred to above, the Seller
shall cease its collection efforts with respect to the Retained Receivables to
be collected by the Seller.  Thereafter, at the request of the Seller the Buyer
will attempt to collect any unpaid Retained Receivable.  The Buyer will make
such collection efforts consistent with its practices for managing and
collecting its own account receivables.  The Seller will compensate the Buyer
for employees used in its collection efforts (based on the Reimbursement Rate)
and reimburse the Buyer for any out-of-pocket costs (including fees and expenses
of consultants).  The Seller will designate a single representative to act as
liaison with the Buyer and to monitor the Buyer's collection efforts pursuant to
this Section 7.7.  The Buyer will provide such information relating to the
Retained Receivables and the Buyer's collection efforts as the Seller may
reasonably request from time to time, and will in any event deliver to Seller,
at least once per month, a reasonably detailed report of collections.

          (c)  All cash, checks or other property which the Buyer shall receive
in respect of the Retained Receivables (whether during or after the 75-day
period when the Seller will collect the Retained Receivables on its own behalf)
shall be held by the Buyer separate and apart from its own property and
delivered, in the form received, to the Seller as promptly as practical (and not
later than three business days after receipt).

     7.8. REMOVAL OF EXCLUDED EQUIPMENT.  Within thirty (30) days after the
Closing Date, the Seller will remove from the Owned Real Property all of those
items described on SCHEDULE 1.2(j) hereto and located on the Owned Real
Property, subject to Section 7.18 in the case of the RVR 7200 described therein.
The Seller shall effect such removal in compliance with all applicable Laws (as
defined in Article 12).  As between the Buyer, on the one hand, and the Seller,
on the other hand, effective as of the Closing the Seller shall be responsible
for the disposal of all such equipment and shall complete such disposal in
compliance with all applicable Laws.

     7.9. EQUIPMENT DISPOSAL.  As between the Buyer, on the one hand, and the
Seller, on the other hand, effective as of the Closing the Buyer shall be
responsible for the disposal of all Equipment and Vitrification Equipment
transferred to the Buyer and, if the Buyer chooses to or is required to dispose
of any such Equipment, it shall complete such disposal in compliance with all
applicable Laws.

     7.10. AUDITS.

          (a)  In the event that the Buyer requires audited financial statements
for the VECTRA Waste Business, the Seller will obtain audited financial
statements for the VECTRA Waste Business on behalf of the Buyer satisfying the
requirements of Molten Metal Technology, Inc., a Delaware corporation and the
parent of the Buyer ("MMT"), under Item 7 of Form 8-K (the "AUDITED
FINANCIALS").  The Seller will cause the Audited Financials to be prepared as
promptly as practicable but in any event in time for MMT to satisfy its
obligations under Item 7 of Form 8-K.  The Seller will cause its independent
accountants, Ernst & Young LLP ("E&Y"), to provide whatever consents and audit
opinions

are required in order for MMT to file the Audited Financials as part of its
filings under the Securities Exchange Act of 1934, as amended, or as part of any
registration statement filed under the Securities Act of 1933, as amended.  The
Seller agrees to allow MMT and the Buyer reasonable participation in the audit
process, and the right to review and approve the terms of the Seller's
engagement letter with E&Y.

          (b)  The Buyer agrees to reimburse the Seller for the cost of Seller's
personnel involved in preparing the Audited Financials (based on the
Reimbursement Rate) plus out-of-pocket expenses (including fees and expenses of
consultants).  In addition, the Seller agrees to pay for the cost of E&Y
auditing the Audited Financials, to the extent incurred in accordance with the
engagement letter referred to in paragraph (a) above, and providing any consents
and opinions referred to in paragraph (a) above.

     7.11. QUALITY ASSURANCE.  The Seller will make available to the Buyer the
Seller's quality assurance program pursuant to the procedures and for the period
described in EXHIBIT D hereto.

     7.12. GUARANTIES AND INDEMNITIES.  Attached as SCHEDULE 7.12 is a list of
existing bonds, letters of credit, guaranties and similar credit supports
outstanding in connection with the Assumed Waste Contracts (the "SUPPORT
AGREEMENTS").  The Buyer agrees to reimburse the Seller for the material deposit

will not include the payment of any consent fee or similar amount, but which
will include the provision of substitute security of like character, quality and
amount, to obtain the release of the Seller from those other Support Agreements
listed on SCHEDULE 7.12.  The Buyer will consult with the Seller from time to
time concerning the progress made with respect to any such releases, and will
permit the Seller reasonable participation in such process.  In the event that
any such Support Agreements are not released prior to the Closing, the Buyer
will indemnify the Seller with respect to such Support Agreements on the terms
set forth in Section 11.2(ii)(F).

     7.13. OFFICE SPACE.  The Seller agrees to let the Buyer use the Seller's
office space located in Columbia, South Carolina.  The Buyer agrees to pay the
Seller rent at the rate of $6,675 per month for such access.  The Buyer may
terminate its right to access at any time.  The Seller may terminate this access
at any time more than 60 days after the Closing Date upon 15 days prior notice.

     7.14. PROPERTY TAXES.  With respect to real property taxes on the Owned
Real Property and personal property taxes on any of the Equipment, the Seller
shall be responsible for the period prior to the Closing Date and the Buyer
shall be responsible for the period on and after the Closing Date.

for a period ending on the first anniversary of the Closing Date the Buyer and
its Affiliates (which does not include M4 Environmental L.P. or its general

of this Section 7.15), shall not, without the prior written consent of the
Seller, directly or indirectly, solicit the employment of or employ or offer to
employ any employee of the Seller; PROVIDED THAT the Buyer and its Affiliates
may solicit the employment of any persons after their employment has been
terminated by the Seller.  In addition, during this period the Buyer and its
Affiliates will not solicit any employees of the Seller on behalf of M4 if the
Buyer could not do so on its own behalf pursuant to the preceding sentence.

     (b)  For a period ending on the first anniversary of the Closing Date,
neither the Seller nor its Affiliates shall, without the prior written consent
of the Buyer, directly or indirectly, solicit the employment of or employ or
offer to employ any employee of the Buyer or MMT including, without limitation,
any Assumed Employee; PROVIDED THAT the Seller and its Affiliates may solicit

     7.16. LICENSE.  Effective upon the Closing, the Seller hereby grants to the
Buyer a non-exclusive, fully paid, worldwide, perpetual license to use all of
the Seller's currently existing Intellectual Property (i) relating to the "10-
140 cask" or (ii) required to use, lease or operate the "P.A.S casks" included
as part of the Equipment.  The Buyer recognizes that the "10-140 cask" is in

right to sublicense.  At or promptly after the Closing the Seller will provide
the Buyer with copies of all documents and records in the Seller's possession or

relating to services performed and goods sold during the period from and
including January 1, 1997 to but excluding the Closing Date, the Buyer agrees to
include the amount of such unbilled receivables and work in process in the
Buyer's invoices to be sent to customers for the month of January.  Such
invoices shall be prepared jointly by the Buyer and the Seller and sent to

                                CERTAIN COVENANTS

     10.1. CONFIDENTIAL INFORMATION.  At all times from and after the Closing
Date, the Seller shall keep secret and maintain in strictest confidence and
shall not use for its benefit or for the benefit
<PAGE>

                                      -31-


of others any confidential or proprietary information relating to the VECTRA
Waste Business, including, without limitation, all Intellectual Property
(whether or not transferred to the Buyer as part of the Intangibles) and files
and records, other than any of such information that is in the public domain
prior to the date of this Agreement or thereafter comes into the public domain
(unless any of such information is in or becomes in the public domain in whole
or in part due to action or inaction of the Seller in violation of this
Agreement).  The foregoing shall not prohibit use of such information as is
required by applicable Law, or as is necessary to prepare Tax returns or other
filings with governmental authorities for the period (including all prior
taxable years) ending on and including the Closing Date, or to assert or protect
any rights of the Seller under this Agreement, PROVIDED that the Buyer is given
notice and an adequate opportunity to contest such disclosure or to use any
means available to minimize such disclosure (E.G., the "confidential treatment"
provisions of Rule 24b-2 promulgated under the Securities Exchange Act of 1934,
as amended).

          (b)  At all times from and after the Closing Date, the Buyer shall
keep secret and maintain in strictest confidence and shall not use for its
benefit or for the benefit of others any confidential or proprietary information
relating to the Fuels Business, including, without limitation, all Intellectual
Property and files and records, other than any of such information that is in
the public domain prior to the date of this Agreement or thereafter comes into
the public domain (unless any of such information is in or becomes in the public
domain in whole or in part due to action or inaction of the Buyer in violation
of this Agreement) and except to the extent such disclosure is required by
applicable Law, PROVIDED that the Seller is given notice and an adequate
opportunity to contest such disclosure or to use any means available to minimize
such disclosure (E.G., the "confidential treatment" provisions of Rule 24b-2
promulgated under the Securities Exchange Act of 1934, as amended).

     10.2. NONCOMPETITION.

          (a)  The Seller agrees that for a period of three (3) years after the
Closing Date (the "RESTRICTED PERIOD"), it shall not engage directly or
indirectly, whether individually or as a consultant, partner, owner or
stockholder of a corporation, in the (i) handling, processing, transportation or
disposal of Low Level Radioactive Waste (as defined below), (ii) the design,
engineering, manufacture or leasing of processing equipment for Low Level
Radioactive Waste, including without limitation demineralization, dewatering,
reverse osmosis and evaporation equipment, or (iii) the design, engineering,
manufacture or leasing of casks or other containers which are duplicates of the
casks and other containers included as part of the Equipment, other than the so-
called "P.A.S. cask" listed on SCHEDULE 1.1(a).  Notwithstanding the foregoing,
nothing herein shall prohibit the Seller from owning, directly or indirectly,
less than fifteen percent (15%) of any class of securities listed on a national
securities exchange or traded publicly in the over-the-counter market.  In
addition to the foregoing, at no time in the future will the Seller represent to
any Person that the
<PAGE>

                                      -32-


Seller still owns or operates the VECTRA Waste Business or is the successor in
interest of the VECTRA Waste Business.

          (b)  For purposes of this Article 10, "Low Level Radioactive Waste"
means any of (i) ion exchange media used to remove radionuclides from
radioactive liquids, (ii) radioactive water and other liquids and radioactive
sludges, filter media and cartridges, carbon absorbers, sediments, precipitates
or organically contaminated aqueous streams and (iii) "dry active waste" --
paper, plastics, clothes and similar materials that have become radioactively
contaminated.

          (c)  Notwithstanding the provisions of subsection 10.2(a) above, the
Seller shall not be precluded from participating in a teaming agreement where
other members of such team would provide services or products prohibited to the
Seller by the provisions of subsection 10.2(a), provided that the Seller does
not directly or indirectly provide such restricted products or services or
otherwise violate the provisions of subsection 10.2(a).

          (d)  At no time in the future will the Buyer represent to any Person
that the Buyer runs or operates the Fuels Business or is the successor in
interest of the Fuels Business.

          (e)  It is recognized by the parties hereto that damages for breaches
of covenants of the nature contained in Section 10.1 and this Section 10.2 are
difficult if not impossible precisely to prove; therefore, it is agreed that
Sections 10.1 and this Section 10.2 shall be enforceable by mandatory
injunction, in addition to any other remedy available to the Buyer or the Seller
under this agreement or at law or equity.  If any of the restrictions contained
in Section 10.1 and this Section 10.2 shall be deemed to be unenforceable by
reason of the extent, duration or geographical scope or other provision hereof,
then the parties hereto contemplate that the court shall reduce such extent,
duration, geographical scope or other provision hereof and enforce Section 10.1
and this Section 10.2 in its reduced form for all purposes in the manner
contemplated hereby.

     10.3. PREFERRED PROVIDER.  (a)  The Seller agrees that during the
Restricted Period it shall use the Buyer as its preferred provider for the
handling, processing, transportation and disposal of Low Level Radioactive
Waste.  As the preferred provider, in the event any customer of the Seller or
any of its Subsidiaries requests any services that include the handling,
processing, transportation or disposal of Low Level Radioactive Waste, the
Seller will refer such opportunity to the Buyer and permit the Buyer a
reasonable opportunity to bid on such services (either directly or in a teaming
arrangement with the Seller).

          (b)  The Buyer agrees that during the Restricted Period it shall use
the Seller as its preferred provider for any transportation casks.  As the
preferred provider, in the event any customer of the Buyer or any of its
Subsidiaries requests any services that include the design or engineering of
transportation casks, the Buyer will refer such opportunity to
<PAGE>

                                      -33-


the Seller and permit the Seller a reasonable opportunity to bid on such
services (either directly or in a teaming arrangement with the Buyer).

     10.4. IF-300.  The Seller agrees that during the Restricted Period it will
at the request of the Buyer, and subject to availability, lease to the Buyer the
Seller's IF-300 transportation casks at the most favorable rate and terms then
offered by the Seller to third parties.

          the Acquired Waste Business Assets or the VECTRA Waste Business, to
          the extent such liability arises out of any matter that occurred or
          existed on or before the Closing Date; PROVIDED THAT, this

"SPECIFIED MISREPRESENTATION CLAIM"), the claim is asserted in writing by the
party seeking indemnification hereunder no later than March 31, 1998, and
(ii) in the case of any claim arising under Section 11.1(i) and relating to
Section 5.21 or under Section 11.1(ii)(D) (a "TAX CLAIM"), not later than three
(3) months after the expiration of the applicable statute of limitations with

<PAGE>


                                      -36-


Misrepresentation Claim or a Tax Claim, and (y) any claim for indemnification

     11.4. MATERIALITY STANDARDS; DOLLAR THRESHOLDS.

          (a)  For purposes of determining those Losses arising from breaches of
representations, warranties or covenants that will be considered immaterial in
nature and accordingly not subject to indemnification hereunder, the Buyer and
the Seller have agreed to use predictable dollar thresholds as provided in this
paragraph (a).  Accordingly, the Buyer and the Seller agree that with respect to
any representation, warranty or covenant referred to in Section 11.1(i) or
11.2(i), if such representation, warranty or covenant contains a materiality
qualification (E.G., "material," "materially," "material to the VECTRA Waste
Business," "in all material respects," or similar qualifiers), such materiality
qualification shall be deemed to have been met, and such representation,
warranty or covenant shall be deemed to have been breached, if the Buyer and its
Affiliates or the Seller and its Affiliates, as applicable, incurs or is alleged
to have incurred Losses in excess of $25,000 in connection with the matter or
event to which such representation, warranty or covenant relates.

          (b)  Neither the Seller nor the Buyer shall be liable to the other for
any Specified Misrepresentation Claim if the total Losses with respect to such
Specified Misrepresentation Claim do not exceed $25,000 ("MINOR CLAIMS").

          (c)  The Seller shall not be liable to the Buyer and its Affiliates
for any Specified Misrepresentation Claims unless and until the total Losses
suffered by the Buyer and its Affiliates with respect to all Specified
Misrepresentation Claims exceeds $100,000, excluding Losses with respect to
Minor Claims, and then only to the extent of such excess.  The Buyer shall not
be liable to the Seller and its Affiliates for any Specified Misrepresentation
Claims unless and until the total Losses suffered by the Seller and its
Affiliates with respect to all Specified Misrepresentation Claims exceeds
$100,000, excluding Losses with respect to Minor Claims, and then only to the
extent of such excess.

          (d)  The total amount payable by the Seller under Section 11.1(i) with
respect to all Specified Misrepresentation Claims shall be the Purchase Price.
The total amount payable by the Buyer under Section 11.2(i) with respect to all
Specified Misrepresentation Claims shall be the Purchase Price.

          (e)  No claim for indemnification under Section 11.1 or Section 11.2,
other than a Specified Misrepresentation Claim, shall be subject to any
threshold amount or deductible amount or cap on liability.

     11.5. CLAIMS.
<PAGE>

                                      -37-


          (a)  Any party seeking indemnification hereunder (the "INDEMNIFIED
PARTY") shall promptly notify the other party hereto obligated to provide
indemnification hereunder (the "INDEMNIFYING PARTY") of any action, suit,
proceeding, demand or breach (a "CLAIM") with respect to which the Indemnified
Party claims indemnification hereunder, PROVIDED that failure of the Indemnified
Party to give such notice shall not relieve any Indemnifying Party of its
obligations under this Article 11 except to the extent, if at all, that such
Indemnifying Party shall have been prejudiced thereby.  If such Claim relates to
any action, suit, proceeding or demand instituted against the Indemnified Party
by a third party (a "THIRD PARTY CLAIM"), upon receipt of such notice from the
Indemnified Party, the Indemnifying Party shall be entitled to participate in
the defense of such Third Party Claim, and if and only if each of the following
conditions is satisfied, the Indemnifying Party may assume the defense of such
Third Party Claim, and in the case of such an assumption the Indemnifying Party
shall have the authority to negotiate, compromise and settle such Third Party
Claim:

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

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

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

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

          (b)  Notwithstanding the foregoing provisions of this Section 11.5,
(i) no Indemnifying Party shall be entitled to settle any Third Party Claim
without the Indemnified Party's prior written consent unless as part of such
settlement the Indemnified Party is released in writing from all liability with
respect to such Third Party Claim and (ii) no Indemnified Party shall be
entitled to settle any Third Party Claim without the Indemnifying Party's prior
written consent unless as part of such settlement the Indemnifying Party is
released in writing from all liability with respect to such Third Party Claim.

          (c)  In the event one party hereunder should have a claim for
indemnification that does not involve a Third-Party Claim, the party seeking
indemnification
<PAGE>

                                      -38-


shall promptly send notice of such Claim to the other party.  If the latter
disputes such Claim, such dispute shall be resolved by agreement of the parties.

     11.6. METHOD AND MANNER OF PAYING CLAIMS; SET-OFF.  Subject to the
Indemnifying Party's right pursuant to Section 11.5 to defend, negotiate,
compromise and settle a Third Party Claim, the amount of any Claim shall be paid
by the Indemnifying Party forthwith on demand.  The unpaid balance of a Claim
shall bear interest at The First National Bank of Boston's "Base Rate" as in
effect from time to time plus 2% from the date notice thereof is given by the
Indemnified Party to the Indemnifying Party; provided that the Indemnifying
Party shall only be obligated to pay interest on that portion of such Claim
ultimately determined to be owed to the Indemnified Party.  Any amounts owed by
the Seller to the Buyer or one of its Affiliates (whether under this Agreement
or otherwise) may be set off in satisfaction of amounts owed by the Buyer or one
of its Affiliates to the Seller (whether under this Agreement or otherwise) and
vice versa.

     11.7. STRADDLE CLAIMS.  With respect to the indemnification obligations of
the Seller and the Buyer under this Article 11, to the extent that any matter,
event or occurrence exists both before and after the Closing Date, such that the
Buyer and the Seller could both be entitled to indemnification with respect
thereto (such as an ongoing violation of workplace safety rules with respect to
which the Seller or the Buyer is assessed a fine attributable to both pre-
Closing and post-Closing periods), the respective indemnification obligations of
the Buyer and the Seller shall be equitably apportioned between the Buyer and
the Seller based on respective lengths of time, comparative opportunity to
correct or prevent such matter or occurrence, whether or not the underlying
matter or occurrence also gives rise to a breach of any of the representations
and warranties made by any party to this Agreement or other equitable factors.

     11.8. COMED.  With respect to Purchase Order Nos. 356371 and 357372 with
ComEd and ComEd Specification NEC-99-5052 (collectively, the "COMED CONTRACTS"),
notwithstanding any other provision of this Article 11, in no event shall the
Buyer be entitled to indemnification under Article 11 for any claim relating to
the terms and provisions of the ComEd Contracts or the future profitability of
the ComEd Contracts.

     11.9. INSURANCE PROCEEDS.

          (a)  No Indemnified Party shall be obligated to pursue or collect from
any insurer prior to making a claim for indemnification pursuant to this
Article 11 and no Indemnifying Party shall be entitled to postpone performance
of any indemnification obligation under this Article 11 while an insurance claim
is pending.  However, without limiting any of the provisions of Sections 11.1
through 11.8, in connection with any matter subject to indemnification under
this Article 11, all parties shall cooperate with each other in giving notice of
any claim to any insurer (including an insurer of an Indemnified Party) and
shall provide reasonable assistance in the collection of any such claim;
PROVIDED, HOWEVER, that there is no duty to provide notice, cooperate or assist
with respect to an Indemnified
<PAGE>

                                      -39-


Party's insurance policies where the Indemnified Party determines in its sole
discretion that such notice, cooperation or assistance could invalidate any
portion of the coverage available under such policy or result in the imposition
of retroactive premiums or prospective premium increases.  In addition, if an
Indemnified Party makes such a determination after it has notified its insurer,
it shall be entitled to retract such notice.

          (b)  If an Indemnified Party actually receives insurance proceeds, the
amount for which such Indemnified Party is entitled to indemnification under
this Article 11 shall be reduced appropriately.  In the event an Indemnified
Party receives insurance proceeds after being paid by the Indemnifying Party
with respect to an indemnifiable matter under this Article 11, the Indemnified
Party will remit such proceeds to the Indemnifying Party, up to the amount
previously paid by the Indemnifying Party with respect to such matter.  Nothing
in this Section 11.9 shall be deemed to waive or limit the subrogation rights of
any insurer.

                                   ARTICLE 12

                                     GENERAL

     13.1.  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The representations and
warranties of the parties hereto contained in this Agreement or otherwise made
in writing in connection with the transactions contemplated hereby (in each case
except as affected by the transactions contemplated by this Agreement) shall be
deemed material and, notwithstanding any investigation by the Buyer or the
Seller, shall be deemed to have been relied on by the Buyer or the Seller, as
applicable, and shall survive the Closing, and the consummation of the

     with a copy sent contemporaneously to:

     13.4.  ENTIRE AGREEMENT.  This Agreement contains the entire understanding
of the parties, supersedes all prior agreements and understandings relating to
the subject matter hereof and shall not be amended except by a written
instrument hereafter signed by all of the parties hereto.

     13.5.  GOVERNING LAW.  The validity and construction of this Agreement
shall be governed by the internal laws (and not the choice-of-law rules) of the
Commonwealth of Massachusetts.

     13.6.  SECTIONS AND SECTION HEADINGS.  The headings of sections and
subsections and schedules are for reference only and shall not limit or control
the meaning thereof.

     13.7.  ASSIGNS.

          (a)  This Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective heirs, successors and permitted assigns.
Neither this
<PAGE>

                                      -43-


Agreement nor the obligations of any party hereunder shall be assignable or
transferable by such party without the prior written consent of the other party
hereto; PROVIDED, HOWEVER, that nothing contained in this Section 13.7 shall
prevent the Buyer, without the consent of the Seller, from transferring or
assigning this Agreement and its rights and obligations hereunder to another
Subsidiary of MMT.  As provided in the Limited Guaranty, dated as of the date
hereof, delivered by MMT to the Seller (the "LIMITED GUARANTY"), no such
assignment shall relieve MMT of its obligations under the Limited Guaranty.

          (b)  In the event that the Seller, prior to April 28, 1998, sells or
otherwise transfers all or substantially all of its operating assets to any
Person and adopts a plan of liquidation or distribution wherein the Seller plans
to distribute to its shareholders its assets, prior to such distribution the
Seller shall establish a liquidating trust to provide for any obligations of the
Seller to indemnify the Buyer under Section 11.1 of this Agreement.  The Seller
shall transfer the principal in cash or liquid assets as provided in this
Section 13.7(b) to fund the trust to provide for the Seller's contingent
liabilities under its indemnification obligations.  Upon formation, the trust
principal deposited shall be $700,000.  The Seller may satisfy its obligation to
the Buyer under this Section 13.7(b) if in connection with the sale or other
transfer of all or substantially all its operating assets to a Person, as a
condition of such sale or transfer, the acquiring Person agrees in writing to
assume the Seller's obligations for indemnification of the Buyer under Section
11.1 of this Agreement, provided, however, that such assumption shall not cause
the acquiring Person to be limited by the restrictions on the Seller in Sections
10.2 and 10.3 of this Agreement.  In any event, in the case of a sale or other
transfer of all or substantially all of its operating assets, the Seller agrees
to give notice to the Buyer of such sale and an opportunity to take possession
of Seller's books and records relating to the VECTRA Waste Business for periods
prior to Closing under this Agreement.  To the extent permitted by applicable
law, such notice shall be delivered as far in advance of the consummation of
such transaction as is practical.  The Seller and/or the liquidating trustee
shall retain rights of access to such books and records as may be necessary to
complete the liquidation or as may be reasonably required in connection with any
tax determination, matter or claim or contractual obligation of the Seller to
third parties, or to prosecute or prepare for the prosecution of any claims
against third parties by the Seller relating to conduct by the Seller of the
VECTRA Waste Business, or in connection with any government investigation of the
Seller.  In the event of a creation of a liquidating trust pursuant to this
Section 13.7(b), the trustee shall hold the assets of such trust under
commercially reasonable terms given the facts and circumstances at such time and
the Seller's obligations for indemnification of Buyer under Section 11.1 of this
Agreement; PROVIDED, HOWEVER, that in the absence of specific pending claims at
such time, the amount of which if adversely determined would preclude
distribution, the principal of the liquidating trust shall be reduced and
distributed to the former VECTRA shareholders on the following schedule; first
anniversary of the creation and funding of the trust, one-half of the balance;
eighteen months from the creation and funding of the trust, one-half of the then
balance; and second anniversary of the creation and funding of the trust, the
balance.

     13.8.  SEVERABILITY.  In the event that any covenant, condition, or other
provision herein contained is held to be invalid, void, or illegal by any court
of competent jurisdiction, the same shall be deemed to be severable from the
remainder of this Agreement and shall in no way affect, impair, or invalidate
any other covenant, condition, or other provision contained herein.

     13.9.  FURTHER ASSURANCES.  The parties agree to take such reasonable steps

respect to calculation of gain, loss and basis with reference to the allocations
of the Purchase Price made pursuant to Article 2 hereof.  The parties hereto
shall not take any actions or positions inconsistent with the obligations set
forth herein.  Both the Buyer and the Seller agree to file with the Internal
Revenue Service an IRS Form 8594 (Asset Acquisition Statement under Section
1060) with respect to the acquisition by the Buyer of the Acquired Waste
Business Assets, with their respective federal income tax returns for the year
in which the Closing Date occurs, consistent with the allocations made pursuant
to Section 2.1.

     13.11.  NO IMPLIED RIGHTS OR REMEDIES.  Except as otherwise expressly
provided herein, nothing herein expressed or implied is intended or shall be
construed to confer upon or to give any person, firm or corporation, other than
the Seller and the Buyer and, for purposes of Article 11, their Affiliates, any
rights or remedies under or by reason of this Agreement.

     13.12.  COUNTERPARTS.  This Agreement may be executed in multiple
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     13.13.  SATISFACTION OF CONDITIONS PRECEDENT.  Each of the Seller and the
Buyer will use its best efforts to cause the satisfaction of the conditions
precedent contained in this Agreement; PROVIDED, HOWEVER, that nothing contained
in this Section 13.13 shall obligate either party hereto to waive any right or
condition under this Agreement.

     13.14.  PUBLIC STATEMENTS OR RELEASES.  Each of the parties hereto agrees
that prior to the consummation of the Closing no party to this Agreement will
make, issue or release any public announcement, statement or acknowledgment of
the existence of, or reveal the status of, this Agreement or the transactions
provided for herein, without first obtaining the consent of the other party
hereto.  Nothing contained in this Section 13.14 shall prevent either party from
making such disclosures as such party may consider necessary to satisfy such
party's legal or contractual obligations.

     13.15.    WAIVER OF JURY TRIAL.  EACH PARTY HERETO WAIVES ITS RIGHT TO A
JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN
CONNECTION WITH THIS AGREEMENT, ANY AGREEMENT, CONTRACT OR OTHER DOCUMENT OR
INSTRUMENT EXECUTED IN CONNECTION HEREWITH, OR ANY OF THE TRANSACTIONS
CONTEMPLATED HEREBY.

     13.16.  CONSTRUCTION.  The language used in this Agreement will be deemed
to be the language chosen by the parties to express their mutual intent, and no
rule of strict construction will be applied against any party.  The word
"including" as used in this Agreement is to be construed as "including without
limitation", whether or not so expressed.

     13.17.    MEDIATION.  (a)  No judicial proceedings relating to any dispute,
claim or controversy arising out of, connected with or relating to this
Agreement or any other Transaction Document ("DISPUTES") may be instituted until
(i) the party alleging a Dispute (the "CLAIMANT") shall have provided written
notice to the party purportedly responsible for the alleged Dispute (the
"RESPONDENT") of that party's intent to mediate the Dispute; and (ii) the
Claimant and the Respondent shall have not resolved the Dispute within the
thirty  days after the party seeking to institute proceedings shall have made
members of its senior management available to discuss the issues with member of
the other party's senior management.  For purposes of this paragraph, "senior
management" shall include, with respect to the Seller, its president and chief
financial officer and with respect to Buyer, its president and treasurer.  All
applicable statutes of limitation shall apply to any Dispute.

     (b)  This Section 13.17 shall in no way affect the right of any party to
seek (i) such interim relief, and only such interim relief, as may be required
to maintain the status quo in aid of the pending mediation in any court of
competent jurisdiction, (ii) to seek any injunctive or equitable relief when
such party deems it appropriate or (iii) to implead any party in connection with
