Item 2.  Acquisition or Disposition of Assets.

         On November 29, 1995, GTS Duratek, Inc. (the "Company") acquired 80%
of the outstanding capital stock of Bird Environmental Gulf Coast, Inc.
("BEGCI") from Bird Environmental Technologies, Inc. ("BETI"), a wholly-owned
subsidiary of Bird Corporation ("Bird"), for an aggregate consideration of
$1.00 and the Company committed to invest up to $5.1 million in the business
as described below.  BEGCI owns a hazardous waste recycling facility in San
Leon, Texas, which has suspended operations pending the capital improvements
described below, which are intended to enable the facility to reach its full
design capacity.  At August 31, 1995 (the date of BEGCI's most recently
available unaudited balance sheet), BEGCI had total assets of approximately
$14.1 million, including net fixed assets of approximately $12.6 million.
Under the terms of the purchase transaction, Bird agreed to fund the working
capital deficit of BEGCI as of August 31, 1995 and, accordingly, contributed
to BEGCI approximately $1.3 million upon the closing of the stock purchase.

         The remaining 20% of the outstanding capital stock of BEGCI is owned
by certain individuals who have operated and will continue to operate the
facility and who will remain as minority shareholders (the "Minority
Shareholders").  The Minority Shareholders have entered into employment
agreements providing for incentive compensation tied directly to the
financial performance of the facility.  The Company entered into a
stockholders' agreement with the Minority Shareholders pursuant to which,
among other terms and conditions, it agreed to invest up to $5.1 million in
BEGCI as needed, up to $2.4 million of which will be used for general working
capital purposes and up to $2.7 million of which will be used for capital and
plant start-up expenditures.  The Company expects to make the capital
investments needed to return the BEGCI plant to commercial operations during
the fourth quarter of 1995 and the first quarter of 1996, and expects to
reopen the plant during the second quarter of 1996.  The Company will use its
internal funds for the investment in BEGCI. As part of the purchase
transaction, the Company also acquired through a license arrangement the
exclusive worldwide rights to the patented technology used by BEGCI's
facility to process and treat the hazardous waste. The technology, known as
thermal desorption, was developed by one of the Minority Shareholders.

Item 7.  Financial Statements, Pro Forma Financial Information and Exhibits.

(a) and (b) FINANCIAL STATEMENTS AND PRO FORMA INFORMATION.   It is
impracticable to provide the required financial statements of BEGCI and the
pro forma financial information required by this Item 7 of Form 8-K at this
time.  The required financial statements and pro forma financial information
will be filed as soon as practicable, but no later than February 12, 1996.

(c) EXHIBITS.  The following exhibits are filed with this report, and the
foregoing description is modified by reference to such exhibits:

GTS DURATEK ACQUISITION OF BEGC

              GTS DURATEK ACQUIRES HAZARDOUS WASTE RECYCLING CENTER

     COLUMBIA MD--GTS Duratek (Nasdaq:  DRTK) today announced that it has
acquired 80 percent of the San Leon, Texas,-based Bird Environmental Gulf
Coast (BEGC) hazardous waste recycling center.

     BEGC uses patented technology to produce recyclable products from
hazardous refinery and petrochemical plant sludges under a broad-scope RCRA
Part B permit, which will allow expansion into other waste treatment and
recycling processes.

     GTS Duratek president and CEO, Robert E. Prince, said, "This acquisition
is an important step in expanding into the hazardous waste field where GTS
Duratek can produce reusable, recyclable, value-added end products.
Moreover, coupling BEGC's patented thermal desorption technology with our
melters opens an additional universe of exciting possibilities for both
radioactive and hazardous wastes."

     The facility is located in the Houston-Galveston corridor, one of the
nation's largest refinery and petrochemical centers.  Based on petroleum
industry estimates, disposal or recycling of refinery and petrochemical
process sludges represents a niche market of approximately $700 million per
year.

     GTS Duratek simultaneously acquired worldwide rights to the patented
thermal desorption technology, which reclaims usable fuels from sludges and
leaves a safe, dry, powdery residue.  GTS Duratek sees the technology as an
excellent fit with its waste vitrification (conversion to glass) technology.
The company's engineers and scientists believe the residue can be converted
to glass or a ceramic-like material that can be recycled.  The process is
also expected to enhance GTS Duratek's radioactive waste vitrification
process.

     GTS Duratek purchased the facility from Bird Environmental Technologies,
Inc. for an undisclosed price.  Bird Environmental Technologies, Inc. is a
subsidiary of Bird Corporation, a publicly-traded building material
manufacturer.

     Columbia, MD-based GTS Duratek is an environmental services and
technology firm that is a national leader in radioactive waste vitrification.

     The hazardous waste recycling facility has suspended operations while it
undergoes capital improvements, which will enable the facility to reach its
full design capacity.  GTS Duratek expects to reopen it in the second quarter
of 1996, providing expanded capacity for its "Fortune 500" customer base.
The facility's 20-percent founder-owners will remain with the business to
manage and operate the facility under incentive-based employment contracts.

breach and have received no written notice of any anticipated breach by the
other party to any material contract or commitment to which the Company is a
party.  Except as noted on SCHEDULE 3.14 attached hereto, none of the
Company's material contracts or agreements constitute a Restricted Agreement
or would require the consent or approval of any party thereto, other than
Company, or the consent or approval of any third party in connection with the
consummation of the transactions contemplated hereby.  Except as disclosed on
SCHEDULE 3.14, the Company is not a party to, or bound by, any material
contract or agreement, any term of which materially adversely affects, or
which the Company expects in the future to have a Material Adverse Effect.

terminated at or prior to the Closing).

     SECTION 3.15  TITLE MATTERS.

     The Company has good and marketable title to the Company Assets owned by

other similar statutory liens arising by operation of law in respect of
obligations that are adequately reflected in the Company's balance sheet as
of August 31, 1995, (ii) certain subsurface rights to the Company's real
property (iii) certain exceptions to title listed on the title report

on the real property (collectively Items (i) through (iv) shall be referred
to as the "Encumbrances").  The Encumbrances that exist on the Company's real
property will not in any material way adversely affect the Company's use or
enjoyment of its real property and will not in any material way adversely
affect the Company's operations.  The Company does not lease any real
property.  None of the properties owned by the Company is subject to any
Liens which could reasonably be expected to materially and adversely affect
the assets, properties, liabilities, business, affairs, results of
operations, condition (financial or otherwise) or prospects of the Company.

     SECTION 3.16  LABOR MATTERS.

     To Bird's and BETI's actual or constructive knowledge, the Company has
complied in all material respects with all applicable federal and state laws
relating to the employment of labor including the provisions thereof relating
to wages, hours, collective bargaining and the payment of social security and
taxes and is not liable for any arrears of wages or any tax or any penalty
for failure to comply with any of the foregoing.  No labor dispute, strike,
work stoppage, employee action or labor relations problem of any kind which
has affected or may affect Company has occurred since the inception of
Company or, to BETI's and Bird's knowledge, is currently pending or
threatened.

     SECTION 3.17  EMPLOYEE BENEFIT PLANS AND PENSION PLANS.

     Copies of all of the Company's employee policy manuals have been
provided to GTSD, which policy manuals contain a description of all material
employee benefit plans and pension plans of the Company.  The Company's
employee benefit plans and pension plans comply in all material respects with
applicable laws relating thereto and have been maintained in accordance with
their plan documents.  The Company has no liability (whether actual,
contingent, with respect to any of its assets or otherwise) with respect to
any of its employee benefit plans and other pension plans other than as
adequately reflected in the Financial Statements.  The Company, GTSD or any
of GTSD's Affiliates will have no liability with respect to any benefit plans
or pension plans of BETI or BETI's control group as defined in Section
414(b), (c), (m) or (o) of the Code.  None of the Company's employee benefit
plans and other pension plans contains any provisions which would prohibit
the transactions contemplated by this Agreement or which would give rise to
any severance, termination or other payments or liabilities as a result of
the transactions contemplated by this Agreement.  SCHEDULE 3.17 attached
hereto contains the most recent quarterly listing of workers' compensation
claims and a schedule of workers' compensation claims of the Company for the
last three fiscal years.

     SECTION 3.18  INSURANCE.

     The Company maintains and has maintained all such general liability,
pollution liability, product liability, fire, casualty and motor vehicle
insurance set forth on SCHEDULE 3.18.  All such insurance policies continue
to be in full force and effect, and the Company is in compliance with all
requirements and provisions thereof.  True and correct copies of all
insurance policies relating to such coverage have been provided by the
Company to GTSD.  No notice of cancellation has been given to or received by
the Company with respect to any of its insurance policies, and no such
policies are subject to any retroactive rate or audit adjustments or
coinsurance arrangements.  The Company, BETI and Bird have no reason to
believe that the pollution liability insurance coverage will not be renewed
upon expiration thereof at premiums substantially equivalent to those
currently being paid by the Company.  The Company is not currently involved
in any projects and, accordingly, the Company is not currently required to
post any completion performance and other bonds and indemnities.  The
Company, BETI or Bird


                                     -13-

<PAGE>

has provided GTSD with a list of all property damage, personal injury claims
and workers' compensation claims asserted against the Company with respect to
the Company's Business during the past five (5) years involving any claim in
excess of $10,000.  The Company has not received any notice from any
insurance company or insurance board of underwriters of the existence of any
default or unsafe condition with respect to the Property that remains
unsatisfied or uncured or that will remain unsatisfied or uncured as of the
Closing Date.

     SECTION 3.19  CONDITION OF COMPANY ASSETS.

     (a)  The Company Assets include all assets, properties, licenses and
other agreements necessary for the continued conduct of Company's Business
after the Closing in substantially the same manner as conducted prior to the
Closing.

     (b)  Attached as Schedule 3.19(b) is a complete and accurate summary of
all of the Tangible Operating Assets of Company.

     SECTION 3.20  INTELLECTUAL PROPERTY.

     (a)  SCHEDULE 3.20 hereto contains a complete and accurate list of all
patents, trademarks, servicemarks and copyrights (registered or
unregistered), trade names, assumed names, brand names and all applications
therefor, owned, used or filed by the Company and the Company has sufficient
trademarks, trade names, service marks, patent rights, copyrights,
manufacturing processes, formulae, applications, trade secrets, know how,
licenses, approvals and governmental authorizations (or rights thereto)
(collectively, the "Intellectual Property") to conduct its business as
conducted prior to the Closing Date except where the absence of such
Intellectual Property would not have a Material Adverse Effect.  Except as
set forth in SCHEDULE 3.20 attached hereto, the patents, trademarks and the
copyrights that constitute Intellectual Property are valid, subsisting and
enforceable, and the patents, registered trademarks and registered copyrights
are duly recorded in the name of Company.

     (b)  The Company has the right, free from any Liens, to use the
Intellectual Property and the consummation of the transactions contemplated
hereby will not alter or impair any such rights. Except as set forth in
SCHEDULE 3.20 attached hereto, within the last five years, no claims have
been asserted by any entity or person with respect to, or challenging or
questioning, the ownership, validity, enforceability or use of the
Intellectual Property by the Company, nor, to the knowledge of BETI and Bird,
is there a valid basis for any such claim.  The use or other exploitation of
such Intellectual Property by the Company prior to the Closing has not
infringed the rights of any other entity or person.  To the best of BETI's
and Bird's knowledge, no entity or person is infringing the rights of the
Company with respect to such Intellectual Property and the Company has no
reasonable basis to claim such infringement.  SCHEDULE 3.20 attached hereto
sets forth a complete and accurate list of all license agreements between
Company and third-parties with respect to the use of the Intellectual
Property.

provisions shall not be applicable to any disclosure or use of confidential
information or knowledge that can be demonstrated to have (i) been publicly
known prior to the date of this Agreement, (ii) become well known by
publication or otherwise not due to the unauthorized act or omission on the

     The Company and Bird covenant and agree that they shall share equally

     SECTION 5.10  CLOSURE TRUST FUND.

     The parties hereto covenant and agree that all contributions by, or on

to that certain Trust Agreement between the Company, as grantor, and Texas
Commerce Bank, N.A., as trustee, dated December 8, 1992 as required by the
Texas Water Commission, the predecessor to the TNRCC, shall remain an asset
of the Company following the Closing, and Bird, BETI or its Affiliates shall
have no right or claim to such contributions.  The parties further covenant
and agree that the closure trust fund shall not be deemed to be a current
asset for purposes of Bird's obligations pursuant to Section 2.3(d).  GTSD
and GTSD Sub covenant and agree that they will use their reasonable efforts
to cause the Company to self-insure for any of the plant closure obligations
mandated by the TNRCC and, in the event the Company is able to do so within
two (2) years from the date of Closing hereunder, without any additional
direct or indirect cost to the Company, effect on the Company's credit, or
credit enhancement by GTSD or its Affiliates, it will distribute any funds
contributed by the Company, BETI or Bird prior to the Closing and received
from the termination of the trust fund, less any reasonable out of pocket
expenses incurred by GTSD, the Company or their Affiliates in connection
therewith, promptly to Bird.  In the event the Company is able to reduce the
plant closure obligations mandated by the TNRCC within two (2) years from the
date of Closing hereunder, it will distribute to Bird a portion of the funds
contributed by the Company, BETI or Bird prior to the Closing, and such
portion shall equal the product of the aggregate amount of funds contributed
prior to the Closing and the percentage reduction in the aggregate funding
obligation of $2 million.  The distributions to Bird required by the previous
sentence will be made either (i) when funds are released from the trust fund,
(ii) as the annual payments to the trust fund are reduced to the extent of
such reduction or (iii) when the trust fund is terminated earlier than when
it would have terminated otherwise but for the reduction.

     SECTION 5.11  KNOWLEDGE OF THE COMPANY.

     For purposes of Article III hereof, the knowledge of the Company or the
Minority Shareholders shall not be imputed to the knowledge of Bird or BETI

     The Company agrees to assume the current leases for the Company's
automobiles that are reflected on SCHEDULE 5.12 hereto pursuant to the terms

that, in the judgment of such Indemnitee, may result in the incurrence by
such Indemnitee of Losses for which such Indemnitee would be entitled to
indemnification pursuant to this Agreement, such Indemnitee shall deliver to
the other party or parties who has indemnified such Losses hereunder
("Indemnitor") a written notice describing such claim.  Such Indemnitor may
participate in and, at its option upon acknowledgment of Indemnitee's right
to indemnification for such matter, assume the defense of the Indemnitee
against such claim, including the employment of counsel,


                                     -30-

<PAGE>

who shall be reasonably satisfactory to such Indemnitee.  In such case, any
Indemnitee shall have the right to employ separate counsel in any such action
or claim and to participate in the defense thereof, but the fees and expenses
of such counsel shall not be at the expense of the Indemnitor unless (i) the
Indemnitor shall have failed, within a reasonable time after having been
notified by the Indemnitee of the existence of such claim as provided in the
preceding sentence, to assume the defense of the such claim, (ii) the
employment of such counsel has been specifically authorized in writing by the
Indemnitor or (iii) the named parties to any such action (including impleaded
parties) include both such Indemnitee and the Indemnitor and such Indemnitee
shall have been advised in writing by such counsel that there may be
conflicting interests between Indemnitee and the Indemnitor in the legal
defense thereof.  No Indemnitor shall be liable to indemnify any Indemnitee
for any compromise or settlement of any such action or claim effected without
the consent of the Indemnitor.

     SECTION 8.4  LIMITS FOR RECOVERY OF LOSSES.

     Notwithstanding anything herein to the contrary, BETI and Bird shall not
be liable as Indemnitors for any Losses of Purchaser under this Article VIII
unless and until the aggregate amount of all Losses hereunder by Purchaser

severally liable for all Losses pursuant to Section 8.1(a) of the indemnified
parties identified in Section 8.1 up to a maximum aggregate amount of
$500,000 (in excess of the $50,000 referred to above) and BETI and Bird shall
be jointly and severally liable for all Losses pursuant to Section 8.1(b)(ii)
of the indemnified parties identified in Section 8.1 up to a maximum
aggregate amount of $125,000.

under this Article VIII.

     Recourse under this Article VIII shall be Purchaser's, GTSD's and their
officers, directors, employees, agents, Affiliates, successors and assigns
sole remedy against BETI or Bird.

                            ARTICLE IX:  SURVIVAL

     Except for actions based upon a claim of fraud (which shall survive
without limitation), all representations and warranties made pursuant to or
in connection with this Agreement shall survive the Closing, but shall
terminate two (2) years after the Closing Date; provided, that there shall be
no such termination with respect to any representation or warranty as to
which a bona fide claim has been asserted prior to such date.

invalidity shall not invalidate the entire Agreement.  Such provision shall
be deemed modified to the extent necessary to render it legal, valid and
enforceable, and if no such modification shall render it legal, valid and

     Each of the parties hereto hereby covenants and agrees to perform its
respective obligations under this Agreement, and to cause the business and

further covenant and agree that all contracts and other arrangements between
the Company and

     GTSD and GTSD Sub covenant and agree that they have delivered, or made

     SECTION 4.12  MITIGATION OF INDEMNIFIED LOSSES.

     Each party hereto covenants and agrees that with respect to any Losses
(as defined below) that it incurs for which it is entitled to indemnification
pursuant to Article V hereto, it will use its best efforts to mitigate such
Losses by pursuing valid claims against, or seeking recoveries from,
appropriate third parties, and the amount of any recoveries by the party
incurring such Loss shall reduce on a dollar for dollar basis the amount of
the Loss for purposes of the indemnification pursuant to Article V.

     SECTION 4.13  SCHEDULE DISCLOSURES.

     The parties agree that any fact or circumstance disclosed in schedules
to this Agreement as an exception to a particular representation or warranty
shall also be deemed for all purposes to be a disclosed and agreed to
exception with respect to any other representation or warranty herein to
which the fact or circumstance disclosed may be deemed to be pertinent.  The
parties further agree that any disclosed exception to a particular

                         ARTICLE V:  INDEMNIFICATION

     SECTION 5.1  INDEMNIFICATION BY THE MINORITY SHAREHOLDERS.

     The Minority Shareholders hereby jointly and severally covenant and
agree to indemnify GTSD, GTSD Sub and their officers, directors, stockholders
beneficially owning individually or as a group (within the meaning of Section
13(d) of the Securities Exchange Act of 1934, as amended) ten percent (10%)
or more of the capital stock of GTSD (such person shall be referred to herein
as a "Principal Stockholder"), and their respective successors and assigns
and hold each of them harmless against and with respect to any and all
liabilities, losses, damages, claims, deficiencies, costs and expenses,
interest, awards, judgments and penalties (including, without limitation,
reasonable legal costs and expenses) actually suffered or incurred by them,
(hereinafter, a "Loss"), arising out of or resulting from:

     (a)  the breach of any representation or warranty by the Minority
Shareholders contained herein or in any document delivered hereunder; or

     (b)  the breach of any covenant or agreement by the Minority
Shareholders contained herein.

     Notwithstanding the foregoing, the Minority Shareholders hereby jointly
and severally covenant and agree to indemnify the indemnified parties
specified in this Section 5.1 and their respective successors and assigns and
hold each of them harmless against and with respect to 75% of any Losses
arising out of or resulting from the breach of any representation or warranty
contained in Sections 2.11, 2.18 and 2.20 hereto.

     SECTION 5.2  INDEMNIFICATION BY GTSD AND GTSD SUB.

     GTSD and GTSD Sub hereby jointly and severally covenant and agree to

<PAGE>

     (b)  the breach of any covenant or agreement by GTSD or GTSD Sub
contained herein or in any document delivered hereunder.

     SECTION 5.3  PROCEDURES FOR THIRD PARTY CLAIMS.

     Promptly after the assertion by any third party of any claim against any
party entitled to be indemnified under this Article V (the "Indemnitee")
that, in the judgment of such Indemnitee, may result in the incurrence by
such Indemnitee of Losses for which such Indemnitee would be entitled to
indemnification pursuant to this Agreement, such Indemnitee shall deliver to
the other party or parties who has indemnified such Losses hereunder
("Indemnitor") a written notice describing such claim.  Such Indemnitor may
participate in and, at its option upon acknowledgment of Indemnitee's right
to indemnification for such matter, assume the defense of the Indemnitee
against such claim, including the employment of counsel, who shall be
reasonably satisfactory to such Indemnitee.  In such case, any Indemnitee
shall have the right to employ separate counsel in any such action or claim
and to participate in the defense thereof, but the fees and expenses of such
counsel shall not be at the expense of the Indemnitor unless (i) the
Indemnitor shall have failed, within a reasonable time after having been
notified by the Indemnitee of the existence of such claim as provided in the
preceding sentence, to assume the defense of the such claim, (ii) the
employment of such counsel has been specifically authorized in writing by the
Indemnitor or (iii) the named parties to any such action (including impleaded
parties) include both such Indemnitee and the Indemnitor and such Indemnitee
shall have been advised in writing by Indemnitor's counsel that there may be
conflicting interests between Indemnitee and the Indemnitor in the legal
defense thereof.  No Indemnitor shall be liable to indemnify any Indemnitee
for any compromise or settlement of any such action or claim effected without
the consent of the Indemnitor.

     SECTION 5.4  LIMITS FOR RECOVERY OF LOSSES.

     (a) Notwithstanding anything herein to the contrary, the Minority
Shareholders, either individually or collectively, shall not be liable for
any Losses of GTSD, GTSD Sub, their directors or officers or a Principal
Stockholder of GTSD under this Article V unless and until the aggregate
amount of all Losses hereunder by such persons collectively equals or exceeds
$100,000, in which event the Minority Shareholders shall be jointly and
severally liable (except as otherwise expressly provided herein) for all
Losses in the aggregate greater than $100,000, subject to the limit provided
in Section 5.4(b).

     (b)  The limit for recovery of any Losses of GTSD, GTSD Sub, their
directors or officers or a Principal Stockholder of GTSD under this Agreement
shall be the amount of the Bonus Payments to which the Minority Shareholders
are entitled, whether or not distributed, pursuant to their Employment
Agreements in the case of M. Hogan, B. Hogan and Lucas and, in the case of J.
Hogan, pursuant to his Agreement with the Company dated the date hereof and
attached hereto as APPENDIX III.

                                     -27-

<PAGE>

     (c)  In the event that the aggregate amount of Losses for which GTSD,
GTSD Sub, their directors or officers or a Principal Stockholder of GTSD
seeks indemnification hereunder exceeds the aggregate limit for recovery of
such Losses pursuant to the preceding paragraph, then the put rights of the
Minority Shareholders pursuant to Section 8.1 hereof shall be suspended until
such time as GTSD or GTSD Sub, as applicable, has received distributions
representing its share of the Company's profits, or there are sufficient
lawful funds to make distributions representing its share of the Company's
profits (in either case, in excess of any liquidation preference of the
Preferred Stock) equal to the amount that the aggregate Losses of GTSD, GTSD
Sub, their officers or directors or the Principal Stockholders of GTSD exceed
the limit for recovery of such Losses pursuant to the preceding paragraph.

     (d)  This Article V provides the sole and exclusive remedies of GTSD,
GTSD Sub and their officers and directors and the Principal Stockholders of
GTSD against the Minority Shareholders under this Agreement, except for
equitable remedies that may be available.

     SECTION 5.5  WAIVER OF CONTRIBUTION.

     None of the Minority Shareholders shall have any right to seek
contribution from the Company in the event that any of the Minority
Shareholders is required to make any payments under this Article V.

     SECTION 5.6  HOLDBACK, RIGHT OF SETOFF.

     The Minority Shareholders agree that, upon a final, non-appealable
adjudication or a final, non-appealable arbitrator's determination that the
Minority Shareholders are liable for indemnity payments, the Company, GTSD or
GTSD Sub may hold back and set off the amount of any claim made by such party
against the Minority Shareholders under Article V of this Agreement against
the amount that may otherwise be due to the Minority Shareholders as a Bonus
Payment pursuant to their Employment Agreements in the case of M. Hogan, B.
Hogan and Lucas and in the case of J. Hogan pursuant to his agreement with
the Company attached hereto as APPENDIX III.  GTSD and GTSD Sub agree that
they will not seek or exercise any right to hold back or set off the amount
of any claim against any Minority Shareholders for indemnity or for any other
claim unless and until such liability of the Minority Shareholders to GTSD or
GTSD Sub is determined by a final, non-appealable adjudication or arbitral
award.

                             ARTICLE VI: SURVIVAL

     Except for actions based upon a claim of fraud (which shall survive
without limitation), all representations and warranties made pursuant to or
in connection with this Agreement shall survive the date hereof, but shall
terminate two and one-half (2-1/2) years after the date hereof; provided,
that there shall be no such termination with respect to any representation or
warranty as to which a bona fide claim has been asserted in writing and on
which a judicial or arbitration proceeding has been commenced prior to such
date.  All covenants and agreements of the parties

                                     -28-

<PAGE>

contained (other than those in Articles II and III and unless expressly
provided otherwise) shall survive and terminate in accordance with Article X.

         ARTICLE VII:  RESTRICTIONS ON TRANSFER; VOLUNTARY TRANSFER;
                              INVOLUNTARY TRANSFER

     SECTION 7.1  RESTRICTIONS ON TRANSFER.

     Except as provided under Section 7.2 below, no Minority Shareholder
shall sell, transfer, give, pledge, encumber or otherwise dispose of (a
"Transfer") any Shares without the written consent of (i) the Company and
(ii) GTSD Sub, which consent may be withheld for any reason or for no reason,
except in accordance with the terms of this Agreement, except for Permitted
Transfers.  Any attempted Transfer in violation of this Agreement shall be
null and void and not recognized for any purpose. Notwithstanding anything
contained herein to the contrary, no Shares may be transferred by the
Minority Shareholders to any Person (including, without limitation, a
trustee, grantor or beneficiary of any trust, or a proposed transferee under
Section 7.2 hereof) unless such person is or becomes a party to this
Agreement by delivering a copy of this Agreement to the Company bearing the
signature of such person on a counterpart signature page and agrees to be
bound by all of the provisions of this Agreement.

     SECTION 7.2  RIGHT OF FIRST REFUSAL UPON VOLUNTARY TRANSFER OF SHARES BY
MINORITY SHAREHOLDERS.

     A Minority Shareholder may Transfer his Shares without restriction
provided that he has held the Shares for four (4) years from the date hereof
and he complies with the provisions of this Section 7.2, or, if prior to four
(4) years from the date hereof, the Transfer is a Permitted Transfer.  If a
Minority Shareholder desires to Transfer all or any number of shares of Stock
to any other party in a bona fide transaction other than a Permitted
Transfer, such Minority Shareholder (a "Transferring Shareholder") shall be
obligated to offer those Shares (the "Offered Shares") for purchase by the
Company and GTSD Sub as hereinafter provided.

          (a)  NOTICE OF TRANSFER.  The Transferring Shareholder shall give
written notice of the proposed Transfer (the "TRANSFER NOTICE") to the
Company and GTSD Sub, stating the date the Transfer Notice is mailed or sent
to the Company and GTSD Sub, the number of Offered Shares the Transferring
Stockholder wishes to Transfer, the name and address of the proposed
transferee, and, if the proposed transfer is a sale, the per-share price
offered by the proposed transferee and the other terms of the transfer.

          (b)  COMPANY'S OPTION TO PURCHASE.  The Company may purchase all or
any of the Offered Shares for the price and upon the other terms hereinafter
provided by giving written

                                     -29-

<PAGE>

notice to the Transferring Shareholder within twenty (20) days after the date
of the Transfer Notice stating the number of Offered Shares which the Company
desires to purchase.

          (c)  GTSD SUB'S OPTION TO PURCHASE.  (i) If any Offered Shares are
not to be purchased by the Company pursuant to Section 7.2(b), GTSD Sub may
purchase such Offered Shares for the price and upon the other terms
hereinafter provided, by giving written notice to the Transferring
Shareholder within thirty (30) days after the date of the Transfer Notice of
the number of Offered Shares that GTSD Sub desires to purchase.

          (d)  SALE TO THIRD PARTY.  If all of the Offered Shares are not
purchased by the Company and/or GTSD Sub pursuant to Sections 7.2(b) and (c)
above, then the Transferring Shareholder may sell the Offered Shares to the
proposed transferee upon terms and conditions no more favorable to the
proposed transferee than those specified in the Transfer Notice, subject to
the remaining provisions of this Agreement, including, without limitation,
that the proposed transferee shall become a party to this Agreement.

          (e)  REOFFER ON FAILURE TO SELL.  If the Transferring Shareholder
fails to consummate a Transfer to the proposed transferee within sixty (60)
days after the expiration of GTSD Sub's option described in Section 7.2(c)
above, then no sale or transfer of the Offered Shares may be made thereafter
to the proposed transferee or to any other transferee without again complying
with the provisions of this Section 7.2.

     SECTION 7.3  OPTION UPON INVOLUNTARY TRANSFER.

     If any shares of Stock are transferred by operation of law to any person
other than the Company or GTSD Sub except by means of a Permitted Transfer,
such transfer shall be deemed a Transfer.  At such time as the Company has
any written notice specifying such a Transfer, a Transfer Notice under
Section 7.2 hereof shall be deemed to have been given, the Company and GTSD
Sub may purchase the Shares upon the same terms as set forth in Section 7.2.
In the event of an involuntary Transfer pursuant to this Section 7.3, the
purchase price for the shares of Stock so transferred shall be deemed to be
the "fair market value" of such shares of Stock as determined in accordance
with Section 8.3 below.

     SECTION 7.4  RIGHT OF FIRST OFFER UPON TRANSFER OF SHARES BY GTSD.

     GTSD Sub may Transfer its Shares without restriction provided that it
has complied with the provisions of this Section 7.4.  If GTSD Sub desires to
Transfer all or any of its Shares, it shall be obligated to offer those
Shares (the "Offered Shares") for purchase by the Minority Shareholders as
hereinafter provided.

          (a)  NOTICE OF TRANSFER.  GTSD Sub shall give written notice of its
desire to Transfer shares of Stock of the Company (the "GTSD TRANSFER
NOTICE") to the Minority

                                     -30-

<PAGE>

Shareholders, stating the date the Transfer Notice is mailed or sent to the
Minority Shareholders and the number of Shares that GTSD Sub desires to
Transfer.

          (b)  MINORITY SHAREHOLDERS OFFER TO PURCHASE.  Any of the Minority
Shareholders desiring to purchase all or any of the Shares offered by GTSD
Sub shall submit to GTSD Sub a written offer specifying the number of Shares
that it wishes to purchase, the purchase price for such shares and the terms
of consideration if other than cash.  Any Minority Shareholders desiring to
offer to purchase the Shares of GTSD Sub must provide the written offer to
GTSD Sub within thirty (30) days after the date of the GTSD Transfer Notice.
GTSD Sub may, in its sole and absolute discretion, accept or reject any
written offers received by any of the Minority Shareholders.  In the event
that GTSD Sub accepts any of the written offers of the Minority Shareholders,
it shall provide written notice of its acceptance to such Minority
Shareholder and the closing for the Transfer of the Shares pursuant to the
terms of the offer shall occur within thirty (30) days of the written
acceptance of the offer by GTSD Sub.

          (c)  SALE TO THIRD PARTY.  To the extent that GTSD Sub has not
accepted any of the offers of the Minority Shareholders that may have been
submitted pursuant to Section 7.4(b), GTSD Sub may freely Transfer the Shares
of the Company to a third party provided that (i) such third party has agreed
to become a party to this Agreement and (ii) either (x) such third party
agrees to assume the obligations of GTSD and GTSD Sub hereunder, with the
written consent of the Minority Shareholders, which consent will not be
unreasonably withheld, it being agreed that the Minority Shareholders refusal
to consent may be based on their reasonable assessment of the
creditworthiness of such third party and the ability of such third party to
perform its obligations under this Agreement or (y) GTSD reaffirms to the
reasonable satisfaction of the Minority Shareholders that the GTSD Guaranty
Agreement executed in connection herewith shall remain in effect, but shall
by virtue of such affirmation be automatically modified to provide that (i)
GTSD's liability to the Minority Shareholders is secondary to the liability
of the transferee and (ii) the Minority Shareholders are required to pursue
all legal and equitable remedies against such transferee prior to pursuing
such remedies against GTSD.

          (d)  REOFFER ON FAILURE TO SELL.  If GTSD Sub fails to consummate a
Transfer permitted by Section 7.4(c) to a third party within 180 days after
the expiration of the offer period to the Minority Shareholders pursuant to
Section 7.4(b) above, then no Transfer of the Shares owned by GTSD Sub may be
made thereafter to any third party without again complying with the
provisions of this Section 7.4.

     SECTION 7.5  PERMITTED TRANSFERS.

     Notwithstanding anything in this Agreement to the contrary, each
Minority Shareholder and subsequent transferees of Stock who acquired such
shares in a Permitted Transfer (as defined below) shall be entitled to
Transfer (whether voluntarily or by operation of law) any of such shares of
Stock free of any restriction on Transfer or right of any other person to
purchase such Stock provided that such Transfer is to the following classes
of transferees
                                     -31-

<PAGE>
("Permitted Transfers"): (a) another Minority Shareholder and to persons to
whom such other Minority Shareholder could transfer his Shares in a Permitted
Transfer, (b) a Minority Shareholder's parents, brothers, sisters, children,
grandchildren and spouse provided that such Minority Shareholder (or other
Minority Shareholders) retains the right to vote, or to control the vote of,
the Shares so transferred by means of a proxy, voting trust or voting
agreement to the reasonable satisfaction of GTSD and its counsel and (c)
trusts, family partnerships or other entities the equity or beneficial
ownership of which is held by, or for the benefit of, persons to whom the
Minority Shareholder would be entitled to make a direct Transfer which would
be considered a Permitted Transfer provided that such Minority Shareholder
provided that such Minority Shareholder (or other Minority Shareholders)
retains the right to vote, or to control the vote of, the Shares so
transferred by means of a proxy, voting trust or voting agreement  or by
means of his position as trustee or otherwise to the reasonable satisfaction
of GTSD and its counsel.

                                     -33-

pursuant to Sections 8.2(a) or (b) above by delivering a written notice to
each of the Minority Shareholders stating the number of shares to be

     SECTION 8.3  PURCHASE PRICE.

     The purchase price for the Shares sold and purchased pursuant to this
Article VIII shall be equal to the then current Fair Market Value (as
hereinafter defined) of such shares.  The "Fair Market Value" of a share of
Stock shall be determined by an independent, nationally-recognized, third
party appraiser selected by the parties hereto and such appraiser shall be
qualified to value businesses similar to that of the Company.  If the parties
are unable to agree on an appraiser, then GTSD Sub and the Minority
Shareholders acting collectively shall each select an appraiser meeting the
qualifications specified in the preceding sentence, and the appraisers so
selected shall select a single, neutral and independent appraiser meeting the
qualifications specified in the preceding sentence to conduct the appraisal.
The appraisal shall be completed within sixty (60) days of the date that the
appraiser is engaged and the appraisal shall be final and binding on the
parties for the purpose of the pending sale and purchase of Shares, and any
other sales and purchases of Shares occurring during the next six (6) months.
The cost of the appraisal shall be shared equally between GTSD Sub and the
selling Minority Shareholders.  For any other transaction occurring within
six (6) months of another transaction, either of the parties to such
subsequent transaction may elect to obtain a new appraisal for the Fair
Market Value of the shares of Stock by the method specified herein provided
that the entire cost of such appraisal shall be paid by the party requesting
such new appraisal.  The value of a share of Stock shall be determined by the
appraiser without any discount applied for the minority ownership position of
the Minority Shareholders and without premium applied to the majority
ownership position of GTSD or GTSD Sub.  The parties hereto covenant and
agree that they will disclose to the appraiser so selected and each other
party hereto and their representatives, any and all

                                     34-

<PAGE>
information or documents in their possession that might reasonably be
expected to bear upon the valuation of the Company including, but not limited
to, any future plans or prospects with respect to the Company, the Company
Business, the Company Assets or the Stock of the Company, and any agreements
(written or oral) or plans for public offerings or potential sales of all or
any part of the business, assets or Stock of the Company following or in
connection with the transaction for which the appraisal is prepared.

     The following actions shall require the approval, or the consent, of a
majority of the shares of Stock owned by the Minority Shareholders and their

otherwise be required under the Company's Organizational Documents or
applicable law:

          (f)   any loans to a stockholder or an Affiliate of a stockholder
and/or the pledge of any assets of the Company for a loan for the benefit of

     SECTION 9.3  COMPOSITION OF BOARD OF DIRECTORS.

     For so long as the Minority Shareholders in the aggregate own at least

shall be entitled as a group to designate up to ten percent (10%) of the
number of directors on the Company's Board of Directors, but in any event not
less than one (1) director.  GTSD Sub agrees that it shall vote all of its
shares of Stock for the election of that director or directors nominated by
the Minority Shareholders.  If the Minority Shareholders and their
transferees pursuant to Permitted Transfers in the aggregate own ten percent
(10%) or less of the outstanding shares of Stock of the Company, then GTSD
Sub and the Minority Shareholders shall mutually agree as to the appropriate
level of representation, if any, of the Minority Shareholders on the
Company's Board of Directors.

     The Company shall form a management committee to oversee the operations

serve on such committee as well as any members that GTSD Sub appoints in its
sole discretion.  The management committee would meet at least quarterly.  J.

be invited to attend the management committee meetings.

                           ARTICLE X:  TERMINATION

     This Agreement shall terminate automatically upon (i) the dissolution,
liquidation or winding up of the Company, (ii) the occurrence of any event
which reduces the number of stockholders to one, or (iii) the merger of the
Company into another corporation (provided that the Company is not the
surviving corporation of such a merger and provided, further, that the
holders of a majority of the Stock owned by the Minority Shareholders and
their transferees pursuant to Permitted Transfers vote in favor of or consent
in writing to such merger).  Notwithstanding the foregoing, the merger of the
Company into a newly formed Maryland corporation pursuant to Section 4.6
shall not cause the termination of this Agreement.

     SECTION 11.11  ARBITRATION.

               (a)  Any disputes between the parties relating to the terms of
this Agreement, or the breach thereof, shall be submitted to binding
arbitration in Baltimore, Maryland, in accordance with the rules of the
American Arbitration Association.  In the event that either party desires to
arbitrate any such dispute, such party shall so notify the other party and
the parties shall endeavor, for a period of thirty (30) days, to resolve such
dispute without arbitration.  In the event that the parties cannot resolve
the dispute within such thirty (30) day period, then within ten (10) days
thereafter, the parties shall jointly designate an arbitrator to hear the
dispute, or, if the parties are unable to jointly select an arbitrator, an
arbitrator shall be chosen in accordance with the rules of the American
Arbitration Association.  The decision of the arbitrator shall be binding
upon the parties.

               (b)  The Company, GTSD or GTSD Sub shall pay all of their own
expenses in connection with such arbitration and shall advance payment for
the reasonable expenses incurred by the Minority Shareholders in connection
with such arbitration, including without limitation travel expenses and the
fees and expenses of counsel, provided that the Minority Shareholders shall
be obligated to repay such advance in the event that the arbitrator
determines that the Minority Shareholders did not act in good faith or did
not have a good faith basis to bring or defend the claim.  In the event that
the Minority Shareholders are required to repay such advance, such amount
shall be offset against the amount to be paid to each or all of them pursuant
to Article VIII hereof or to be paid to each or all of them as a Bonus
Payment pursuant to the Employment Agreements or the Hogan Agreement, as
applicable.  The offset described in the preceding sentence shall be the sole
remedy of the Company, GTSD or GTSD Sub to recover the advance.

     SECTION 11.12  SPECIFIC PERFORMANCE.

     The parties acknowledge and agree that the breach of the provisions of
this Agreement could not be adequately compensated with monetary damages, and
the parties hereto agree, accordingly, that injunctive relief and specific
performance shall be appropriate remedies to enforce provisions of this
Agreement and waive any claim or defense that there is an adequate remedy at
law for such breach; provided, however, that, except as expressly provided
herein, nothing herein shall limit the remedies herein, legal or equitable,
otherwise available and all remedies herein are in addition to any remedies
available at law or otherwise.

     SECTION 11.13  SEVERABILITY.

     If any provision of this Agreement shall be held to be illegal, invalid
or unenforceable under any applicable law, then such contravention or
invalidity shall not invalidate the entire Agreement.  Such provision shall
be deemed to be modified to the extent necessary to render it legal, valid
and enforceable, and if no such modification shall render it legal, valid and

                                     -42-

<PAGE>

enforceable, then this Agreement shall be construed as if not containing the
provision held to be invalid, and the rights and obligations of the parties
shall be construed and enforced accordingly.

     SECTION 11.14   NO DRAFTING PRESUMPTION.

     Each of the parties hereto shall be deemed to have participated equally
in the drafting and preparation of this Agreement and, accordingly, no
presumption shall arise concerning the interpretation of any of the
provisions hereof with respect to the party or parties responsible for its
preparation.

context requires, the gender of all words used herein shall include the
masculine, feminine and neuter and the number of all words shall include the
singular and plural.

     SECTION 11.16  AMENDMENT AND WAIVER.

     This Agreement may not be amended or modified except by a written
instrument signed by the parties hereto.  The waiver by any party of such
party's rights under this Agreement in any particular instance or instances,
whether intentional or otherwise, shall not be considered as a continuing
waiver which would prevent subsequent enforcement of such rights or of any
other rights.

     IN WITNESS WHEREOF, this Agreement has been duly executed and delivered
by the parties hereto on the date first above written.

                               W I T N E S S E T H :

any of the Technology, including without limitation, designs and all necessary
information for the manufacture and operation of Desorbers, whether now or
hereafter developed or acquired.

III. DISCLOSURE AND ASSIGNMENT OF TECHNOLOGY (FUTURE)

     All Technology in the Licensed Field which Hogan creates or develops
and comes into being during the term of the Agreement ("Future Technology")
shall be assigned or licensed, as appropriate, to Licensees, or to such party or
parties as the Licensees may designate, and such Future Technology shall be
fully disclosed to Licensees in a timely manner.  Notwithstanding anything
herein to the contrary, all Future Technology (including without limitation any
improvements to the existing Technology and any Patent Rights) developed or
acquired by the Licensees, either singly or jointly with Hogan, during the term
of this Agreement shall be owned by the Licensees and such Licensees shall
retain all rights thereto and all Future Technology (including without
limitation any improvements to the existing Technology and any Patent Rights)
developed or created by Hogan which was funded or sponsored by the Licensees, in
whole or in part, shall be owned by the Licensees and such Licensees shall
retain all rights thereto.  Hogan hereby agrees to assign any and all rights
that he may have to the Future Technology (including any Patent Rights)
described in the preceding sentence to the Licensees.  Notwithstanding any other
provision of this Agreement, if Licensees, or either of them, retain


                                     -3-

and pays Hogan or Val Verde Corporation to do the engineering work for the
specific purpose of modifying the Technology to process a specific type or
quantity of material, such engineering work shall not be considered Future
Technology, but shall be considered part of the Technology, and the royalties
provided for in Section IV shall be paid on the use, sale or leasing of
equipment made pursuant to such engineering work.

IV.  ROYALTY PAYMENTS

     a.   In consideration of the license and rights herein granted, the
Company and GTSD shall pay to Hogan in the manner herein provided unless
terminated as hereinafter provided the following (the following payments
reflect the aggregate amounts to be paid by the Company and GTSD
collectively):

          1.   No payments will be made with respect to the first Desorber or
its replacement located at the Gulf Coast Recycling Center ("GCRC"), and the
Company and GTSD will have a perpetual, royalty free license under Section II
above to operate such Desorber or its replacement, including the right to use
the Technology which is incorporated in the Desorber, notwithstanding any
termination of this Agreement.

          2.   With respect to Desorbers other than the first Desorber or its
replacement, and the operation of similar processes in the Licensed Field,
Licensees will pay Hogan a royalty equal to the greater of (i) $50,000 per
year or (ii) one percent (1.0%) of the net revenues per License Year of the
Company, GTSD and their subsidiaries, Affiliates and sublicensees from the
operation of the Desorbers (exclusive of any revenues generated from the
first Desorber or its replacement at the GCRC and sales or leasing of
equipment) and five percent (5.0%) of the net revenues per License Year of
the Company, GTSD and their subsidiaries, Affiliates and sublicensees from
the sales or leasing of equipment to unaffiliated third parties incorporating
any of the Technology.  The royalty provisions of this paragraph shall govern
until $5.0 million in cumulative royalties have been paid to Hogan and
thereafter the provisions of the following paragraph shall govern the
royalties to be paid to Hogan.

          3.   Once $5.0 million in cumulative royalties have been paid to
Hogan pursuant to the preceding paragraph, the provisions of that paragraph
shall cease to apply and the provisions of this paragraph 3 shall govern.
With respect to Desorbers other than the first Desorber or its replacement,
and the operation of similar processes in the Licensed Field, Licensees will
pay to Hogan a royalty equal to the lesser of (i) $100,000 per year or (ii)
one percent (1.0%) of the net revenues per License Year of the Company, GTSD
and their subsidiaries, Affiliates and sublicensees from the operation of
Desorbers (exclusive of any revenues generated from the first Desorber or its
replacement at the GCRC and sales or leasing of equipment) and five percent
(5.0%) of the net revenues per License Year of the Company, GTSD and their
subsidiaries, Affiliates and sublicensees from the sales or leasing of
equipment to unaffiliated third parties incorporating any of the Technology.


                                     -4-

<PAGE>

          4.   For purposes of this Agreement, the term "net revenues" shall
mean all amounts or proceeds received by the Company, GTSD or their
subsidiaries, Affiliates and sublicensees from the use, sales or leasing of
equipment incorporating the Technology, as applicable, including revenue
received by any of them as a result of operations by other entities, less the
following deductions:  (i) discounts allowed and taken for prompt payment,
(ii) allowances for returns or other trade credits, (iii) all sales, use and
other taxes imposed which are paid to the Licensees by the customer, (iv)
packaging and transportation costs and (v) the cost of services contracted to
other subcontractors providing technologies and services complimentary to and
outside of the Licensed Field and packaged for sale with the Licensed Subject
Matter. For purposes of this Agreement, the "net revenues" from the sales or
leasing of equipment incorporating any of the Technology shall only refer to
the revenues from the sale or leasing of such specific equipment and shall
not include the net revenues from the sales or leasing of equipment not
incorporating the Technology but which may be sold with the equipment
incorporating the Technology as part of an entire system.  When the net
revenues received by the Licensees includes both such types of equipment, the
Licensees and Hogan shall discuss in good faith the portion of the purchase
price for the system that should be allocated to the equipment incorporating
the Technology for purposes of determining the royalty payment pursuant to
this Section IV.

          5.   Notwithstanding anything herein to the contrary, the royalty
obligations provided in this Section IV shall not commence until the Company
has achieved cumulative earnings before interest, taxes, depreciation and
amortization ("EBITDA") during three (3) consecutive months of at least
$75,000 following the date of this Agreement.

          6.   If no royalties are paid to Hogan during the first and second
License Years of this Agreement due to the fact that the Company did not
achieve cumulative EBITDA during three (3) consecutive months of at least
$75,000, then the Company and GTSD may, at their sole discretion, either (i)
make the minimum annual royalty payments of $50,000 per year to Hogan in the
third, fourth and fifth License Years of this Agreement and continue this
Agreement, or (ii) terminate this Agreement pursuant to Section XII hereof,
provided that if such election is not made within 60 days of the end of the
second License Year and Hogan has provided the Company with a written request
to make such election at least 15 days prior to the end of the 60 day period,
then Hogan may elect to terminate this Agreement.

          7.   In the event the United States Government has or obtains
royalty-free rights under the Patent Rights or Technology, any amounts or
proceeds received by the Company, GTSD or their subsidiaries in respect of
any Licensed Subject Matter caused to be manufactured by or through the
Company, GTSD or their subsidiaries and sold, leased or otherwise transferred
to the United States Government or services performed for the United States
Government shall not be included within the definition of "net revenues" and
no royalty shall be required to be paid thereon.


                                     -5-

<PAGE>

V.   AVOIDANCE OF DUPLICATION OF ROYALTY PAYMENTS

     In no event shall more than one royalty payment be due under this
Agreement on the same Licensed Subject Matter or component part thereof,
provided however, that if the Licensees receive from a third party a royalty
for the use of the equipment incorporating the Technology (in addition to the
revenues received by the Licensees for the sale or leasing of such
equipment), such royalty received by the Licensees shall be included in the
royalty calculation of Section IV.

VI.  LICENSEE FEES PAYABLE TO THIRD PARTIES

     In the event Licensees are charged with infringement of a valid patent
or other proprietary rights of a third party or are notified of such
infringement, and an attorney approved by Hogan and Licensees renders an
opinion that an injunction enjoining Licensees from infringing such patent or
proprietary rights would prevent Licensees from practicing in the Licensed
Field or otherwise using the Technology, then any royalty or other
compensation which the owner of such patent or proprietary rights requires
for Licensees to license or otherwise use such patent or proprietary rights
shall be deducted from the royalties payable to Hogan under Article IV hereof.

VII. PAYMENT OF ROYALTIES AND ACCOUNTING

     Royalty payments pursuant to paragraphs 2 and 3 of Section IV(a) shall
be made quarterly, within sixty (60) days of the end of each calendar quarter
of each License Year once the royalty payments commence pursuant to paragraph
5 of Section IV(a).  If paragraph 2 of Section IV(a) is applicable, the
amount paid for each calendar quarter shall be the greater of (i) $12,500 and
(ii) the percentage royalties described in paragraph 2 of Section IV(a) on
the net revenues during the calendar quarter just ended.  If paragraph 3 of
Section IV(a) is applicable, the amount paid for each calendar quarter shall
be the lesser of (i) $25,000 and (ii) the percentage royalties described in
paragraph 3 of Section IV(a) on the net revenues during the calendar quarter
just ended. The net revenues for each calendar quarter shall be reasonably
determined by the Licensees in good faith and shall be subject to an annual
reconciliation within 90 days of the end of each License Year.  All payments
required to be made under this Agreement shall be made in U.S. funds.  At the
time of payment of such royalties, GTSD or the Company shall render to Hogan
a statement in writing showing the computation of such royalties payable for
such calendar quarter or License Year, as applicable.  Notwithstanding
anything herein to the contrary, Hogan shall have no right to dispute or
audit the quarterly payment of royalties, but shall be required to wait until
the completion of the reconciliation within 90 days of the end of the License
Year to exercise his rights pursuant to Section VIII.  Any statement
following the year-end reconciliation that covers the full License Year shall
be conclusively presumed to be accurate and deemed acceptable by Hogan unless
he notifies the Company and GTSD in writing as to any objections within one
(1) year of Hogan's receipt of such statement.  For purposes of determining
the royalty payments owed to Hogan pursuant to Section IV, the first License
Year shall be the calendar year beginning January 1, 1996.  The accounting
shall be in accordance with generally accepted accounting principles.


                                     -6-

<PAGE>

VIII. AUDIT RIGHTS

     Hogan shall have the right, at his option and sole expense, within one
(1) year after receipt of the annual statement for the full License Year
described in the previous section, to have each of Licensee's books and
records relating to the Technology audited by an independent certified public
accountant ("CPA") selected by Hogan and approved by Licensees, such approval
not to be unreasonably withheld provided that the CPA has signed an
appropriate confidentiality agreement.  Licensees will make such books and
records available to such CPA during reasonable business hours.  The CPA
shall agree to advise Hogan only of the accuracy or inaccuracy of Licensees'
statements and the royalty payments to him, and if not accurate, the actual
amounts as computed by such CPA.

IX.  EXPENSES:  PREPARATION, PROSECUTION AND MAINTENANCE OF PATENT RIGHTS.

     a.   Upon request for the duration of this Agreement, Hogan and
Licensees, at Licensees' expense, shall jointly review the question of
patentability or other protection of any idea, work, invention or discovery
which is conceived, invented or discovered by Hogan or Licensees in the
Licensed Field, or any idea, work, invention or discovery which results from
or arises out of any research work conducted by Hogan pursuant to a grant
guaranteed by, or other engagement by, either Licensee irrespective of
whether or not any such idea, work, invention or discovery is included or
required to be included in the Technology.

     b.   Licensees shall have the power and authority to file and prosecute
applications for patents on any idea, invention or discovery in the Licensed
Field in the Licensed Territory and to procure and maintain patents thereon.
The inventor of any such idea, invention or discovery shall, at Licensees'
request, execute such documents and perform such acts as Licensees' counsel
may deem necessary and advisable to perfect the filing of such applications
for patent throughout the world and to assist Licensees in procuring,
maintaining, enforcing and defending patents, and other applicable statutory
protection granted or issued thereon, all at the expense of Licensees.
Patent applications shall be prepared and prosecuted by attorneys selected by
the Licensees, provided that if such patent application relates to an idea,
invention or discovery by Hogan (a "Hogan Invention") such attorneys must be
reasonably acceptable to Hogan.  If the patent application relates to a Hogan
Invention, the Licensees shall provide Hogan with copies of all
correspondence concerning such application and if Licensees decide to abandon
any pending patent applications or issued patents relating to a Hogan
Invention, they shall notify Hogan in writing sixty (60) days prior to the
final date for maintaining the pending patent application or issued patent.

     c.   The Licensees shall pay all attorneys fees and expenses associated
with the preparation, prosecution and maintenance of patent applications and
issued patents that they determine in their discretion to pursue and/or
maintain.


                                     -7-

<PAGE>

     d.   Anything in this Agreement to the contrary notwithstanding,
Licensees may elect to relinquish their exclusive license under any
application for patent or patent included in the Patent Rights by giving
Hogan at least sixty (60) days prior written notice of such election.  Any
such application for patent or patent thereafter shall be excluded from the
Patent Rights and Licensees thereafter shall not be liable for any costs
incurred in the prosecution, procurement, maintenance, enforcement and
defense thereof.

X.   INFRINGEMENT

     a.   Licensees shall have the right, but shall not be obligated, to bring
and prosecute any suit or action against an infringer of any patent included in
the Patent Rights in the name of Licensees and/or Hogan, if appropriate, at
Licensees' cost and expense and for Licensees' own accounting, and in any such
case Licensees shall have control of the conduct or settlement of any such suit
or action.  Any and all recoveries of any kind from any such suit or action
shall be the property of Licensees, except in the event any recoveries are
royalties for past infringement and/or future royalties and/or for a paid-up
license under any patent included in the Patent Rights, then any such recoveries
less pro rata costs incurred by Licensees for attorney's fees, witnesses' fees,
and court and out-of-pocket costs shall be included as net revenues according to
Section IV hereof.  Hogan shall have no obligation to bring and prosecute any
suit or action against an infringer of any patent included in the Patent Rights.

     b.   Should Licensees exercise their rights under Section X(a), Licensees
agree to indemnify and defend Hogan from countersuit by an infringer of any
patent with respect to his role as inventor of the patents.  Such
indemnification is limited to issues related to or arising out of patent
validity or patent infringement only.

     c.   Hogan shall give promptly upon request and without compensation (other
than reimbursement of reasonable out-of-pocket expenses and as provided in this
Article X) all reasonable information and assistance necessary to enable
Licensees to bring and prosecute any such suit or action.

     d.   In the event that Licensees shall fail to cause any infringement of
Patent Rights to terminate or shall fail to bring suit or action against any
such infringer within six (6) months after request in writing from Hogan to do
so, then in such event Hogan shall have the right, but shall not be obligated,
to bring and prosecute any such suit or action in his own name and/or Licensees
names, at Hogan's sole cost and expense, and in any such case, Hogan shall have
sole control of the conduct or settlement of any such suit or action.  Any and
all recoveries for damages, royalties, costs and awards form any such suit or
action shall be the sole property of Hogan, less any costs which may be incurred
by Licensees in support such action or suit.

     e.   Should Hogan exercise his right under Section X(d), Hogan agrees to
indemnify and defend Licensees from countersuit by an infringer of any patent
with respect to Licensees


                                     -8-

<PAGE>

role as licensees.  Such indemnification is limited to issues related to
patent validity or patent infringement only.

     f.   The party not bringing such suit or action shall have the right, at
its sole expense, to be represented by counsel during all proceedings of such
suit or action.

number of days of such License Year after such termination bears to three
hundred sixty-five (365).

XIV. DISPOSITION OF SUBLICENSEES OF LICENSEES

     In the event of termination of this Agreement under Section XII hereof
by any Licensees, any sublicenses theretofore granted by such Licensee shall
terminate, except for the continuing rights of the Licensees under Section
XII.

XV.  RECORDS AND CONFIDENTIAL DATA

     a.   All memoranda, notices, files, records, databases and other documents,
and all copies thereof, made or compiled by Hogan during the term of this
Agreement in the ordinary course of business, or made available to him
concerning the business of the Licensees shall be the Licensees' property and
shall be delivered to the Licensees at their request therefor or automatically
on the termination of this Agreement, provided that Hogan may retain a copy,
subject to the confidentiality restrictions contained herein.  Hogan shall not
at any time during or after the term hereof use for himself or others, or
divulge to others any trade secret or confidential or proprietary business
information, knowledge or data of the Licensees obtained by him as a result of
his relationship with the Licensees unless authorized in writing by the
Licensees or required by law.

     b.   All memoranda, notices, files, records and other information
disclosing any of the Technology shall be retained in confidence by the parties
hereto and their agents, and shall not be disclosed to any third party, except
to the extent reasonably necessary to pursue the business objectives of the
Licensees or to comply with the contractual commitments of this Agreement.

     c.   The parties agree that either the Licensees on the one hand or Hogan
on the other hand will be entitled (without posting bond or other security) to
injunctive or other equitable relief, as deemed appropriate by any such court or
tribunal, to prevent a breach of the other party's obligations set forth in this
Section XV.

XVI. NON-COMPETITION/NON-INTERFERENCE

     Hogan agrees that, for the term of this Agreement and for a period of three
(3) years thereafter, he will not directly or indirectly (i) be employed by or
perform activities on behalf of any Competing Business in any state, country or
other jurisdiction in which the Licensees or any of their affiliates then
conducts business; or (ii) induce any employee of the Licensees or their
subsidiaries to terminate such employment or to become employed by any such
Competing Business.  As used herein, "Competing Business" shall mean any
business (i) then currently deriving revenues from the treatment of any form of
waste through a thermal desorption process or (ii) then currently deriving
revenues from the treatment of any form of waste that then accounts for at least
ten percent (10%) of the revenues of either of the Licensees, irrespective of
the treatment technology used.  To the extent Hogan will be employed by or
perform activities on behalf of a division or subsidiary of a Competing Business
that does not compete, and he can demonstrate to the Licensees' reasonable
satisfaction that such employment or provision of


                                     -11-

<PAGE>

services will not have an adverse competitive effect on the Licensees, such
employment or provision of services shall not be prohibited hereunder.  The
parties acknowledge and agree that the restrictions of this Section XVI have
been carefully negotiated at arm's length and are believed by the parties to
be reasonable and necessitated by legitimate business needs.  In the event
that, notwithstanding the foregoing, any provision set forth in this Section
XVI shall be determined by any competent court or tribunal to be
unenforceable or invalid for any reason, the parties agree that this Section
XVI shall be interpreted to extend only over the maximum period of time for
which it may be enforceable, and/or over the maximum geographical area as to
which it may be enforceable, and/or to the maximum extent in any and all
respects as to which it may be enforceable, all as determined by such court
or tribunal.  The parties further agree that the Licensees will be entitled
(without posting bond or other security) to injunctive or other equitable
relief, as deemed appropriate by any such court or tribunal, to prevent a
breach of Hogan's obligations set forth in this Section XVI.

XVII. TERM OF THE AGREEMENT

     This Agreement shall commence on the date hereof, and unless sooner
terminated as herein provided shall continue in full force and effect until the
expiration of the last expiring patent or patent application included in the
Patent Rights.

XVIII.  WAIVER AND SEVERABILITY

     a.   The waiver by any of the parties of any breach of any provision
hereof by another shall not be construed to be a waiver of any succeeding
breach of such provision or a waiver of the provision itself.

     b.   If one or more of the provisions of the Agreement shall be found to
be illegal, invalid or unenforceable under any applicable law, then such
contravention or invalidity shall not invalidate the entire Agreement.  Such
provision shall be deemed to be modified to the extent necessary to render it
legal, valid and enforceable, and if no such modification shall render it
legal, valid and enforceable, then this Agreement shall be construed as if
not containing the provision held to be invalid, and the rights and
obligations of the parties shall be construed and enforced accordingly.

XIX. NOTICES

     Except as otherwise expressly stated, all notices required to be given
or which may be given under this Agreement shall be in writing and shall be
deemed given upon the earlier of (i) when it is personally delivered, (ii)
three (3) days after having been mailed by certified mail, postage prepaid,
return receipt requested, (iii) two (2) days after having been sent by
recognized overnight delivery service or (iv) one (1) day after having been

XX.  COMPLETE AGREEMENT

     This Agreement contains the complete agreement and understanding between
the parties concerning the subject matter hereof and shall supersede all other
agreements, understandings or commitments between the parties as to such subject
matter.

XXI. ASSIGNMENT

     The obligations and rights of each party hereunder shall not be assignable
without the prior written consent of the other party; provided, however, that
the Licensees may without the consent of Hogan assign this Agreement to (i) an
Affiliate or (ii) any successor owner of the Licensees or their business
resulting from merger, consolidation, sale of the business or otherwise so long
as such successor agrees in writing to assume Licensees' obligations under this
Agreement in a form and manner reasonably acceptable to Hogan.  The parties
hereto agree that following the merger of the Company into the newly formed
Maryland corporation as contemplated by Section 4.6(a) of the Stockholders'
Agreement, this Agreement shall survive such merger, shall be in full force and
effect thereafter and the newly formed Maryland


                                     -13-

<PAGE>

corporation into which the Company is merged shall by virtue of such merger
become a party to this Agreement and assume all of the rights, liabilities and
obligations of the Company under this Agreement.  Subject to the foregoing, this
Agreement shall be binding upon and inure to the benefit of the parties'
respective heirs, legal representatives, successors and assigns.

XXII.  WAIVER, MODIFICATION OR AMENDMENT

     No waiver, modification or amendment of any provision of this Agreement
shall be effective, binding or enforceable unless in writing and signed by all
of the parties hereto.


XXIII. GOVERNING LAW

     The validity of this Agreement and of any of the terms or provisions as
well as the rights and duties of the parties hereunder shall be governed by the
laws of the State of Maryland, without reference to any conflict of law or
choice of law principles in the State of Maryland that might apply the law of
another jurisdiction.

XXIV. ARBITRATION

     a.  Any disputes between the parties relating to the terms of this
Agreement, or the breach thereof, shall be submitted to binding arbitration in
Baltimore, Maryland, in accordance with the rules of the American Arbitration
Association.  In the event that either party desires to arbitrate any such
dispute, such party shall so notify the other party and the parties shall
endeavor, for a period of thirty (30) days, to resolve such dispute without
arbitration.  In the event that the parties cannot resolve the dispute within
such thirty (30) day period, then within ten (10) days thereafter, the parties
shall jointly designate a single neutral and independent arbitrator to hear the
dispute, or, if the parties are unable to jointly select an arbitrator, an
arbitrator shall be chosen in accordance with the rules of the American
Arbitration Association.  The decision of the arbitrator shall be binding upon
the parties.

     b.  The Licensees shall pay all of their own expenses in connection with
such arbitration and shall advance payment for the reasonable expenses incurred
by Hogan in connection with such arbitration, including without limitation
travel expenses and fees and expenses of counsel, provided that Hogan shall be
obligated to repay such advance in the event that the arbitrator determines that
Hogan did not act in good faith or did not have a good faith basis to bring or
defend the claim.  In the event that Hogan is required to repay such advance,
such amount shall be offset against the amount to be paid to Hogan pursuant to
Article VIII of the Stockholders' Agreement or to be paid to Hogan as a Bonus
Payment pursuant to the Agreement with Hogan dated the date hereof.  The offset
described in the preceding sentence shall be the sole remedy of the Licensees to
recover the advance.
