                             WASTE RECOVERY, INC.
                       INCENTIVE STOCK OPTION AGREEMENT

        THIS INCENTIVE STOCK OPTION AGREEMENT ("Agreement"), made and entered
into in Dallas, Texas, as of the 21st day of March, 1995, by and between Waste
Recovery, Inc., a corporation organized and existing under the laws of Texas
(the "Company") and Andrew J. Sabia (the "Participant").

        WHEREAS, Participant is now a full-time employee of the Company, or one
of its subsidiaries, and will render faithful and efficient service; and

        WHEREAS, the Company desires to continue to receive the benefit of
Participant's services and to fully identify his interests with the Company's
future and success; and

        WHEREAS, the Board of Directors ("Board") of the Company and the
stockholders of the Company have heretofore approved the Company's 1989 Stock
Plan for Employees (the "Plan") providing for, among other things, the
granting of stock options under the Plan to certain employees of the Company,
including officers of the Company; and

        WHEREAS, pursuant to the provisions of such Plan, the Board has so
granted and authorized the terms and provisions in this Agreement pursuant to
Section 422 of the Internal Revenue Code of 1986 (the "Code"):

        NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, and other good and valuable consideration, it is
understood and agreed as follows:

        1. OPTION TO PURCHASE.

        (a) The Company hereby grants to Participant an irrevocable right and
nonqualified option ("Option") to purchase from the Company Ten Thousand
(10,000) shares (subject, however, to adjustment as provided in Paragraph 8),
of the common stock, no par value, of the Company (the "Option Shares") upon
the terms and conditions herein contained.

        (b) The purchase price payable to the Company for the shares to be
acquired pursuant to the exercise of this Option will be One and 06/100ths
Dollars ($1.06) per share, which shall be paid to the Company in the manner
hereinafter described at the time of exercise. Such purchase price is referred
to herein as the "Option Price".

        2. EXERCISE OF OPTION.

        (a) Exercisable Option Shares. Participant can exercise this Option on
a cumulative basis to the extent hereinafter provided with respect to all or
any part of the number of "Exercisable Option Shares" subject to this Option,
and such right shall be a continuing one during the term of the Option as
provided in paragraph 3 hereof, until this Option has been fully exercised with
respect to the number of Option Shares stated in paragraph 1. "Exercisable
Option Shares" shall be the Option Shares granted, in paragraph 1 hereof, less
Option Shares previously exercised.

        (b) Exercise After Participant's Death. Upon the death of Participant,
this Option shall still be exercisable in full with respect to Option Shares
which are Exercisable Option Shares on the date of Participant's death, and may
be exercised in whole or in part by the estate of the Participant or by such
person or persons to whom this Option shall be transferred by the Will of
Participant, or by the applicable laws of descent and distribution, but only
within one hundred eighty (180) days after the Participant's death, or within
the unexpired term of this Option, whichever is shorter, at which time this
Option shall lapse and become void.

        (c) Exercise After Termination of Employment. If the Participant shall
voluntarily terminate his employment without the consent of the Company (of
which the Board shall be the sole judge), his rights under any then outstanding
Options shall terminate immediately. In the event that the Participant shall
voluntarily terminate his employment with the consent of the Company (regarding
which the Board shall be the sole judge), or in the event that the
Participant's employment shall be involuntarily terminated by the Company other
than for cause (regarding which the Board shall be the sole judge), or in the
event of a Participant's retirement under any retirement plan of the Company,
its parent, or any of its subsidiaries, an Option shall be exercisable by the
Participant at any time prior to the expiration date of such Option or within
three (3) months after the date of such termination of employment, whichever is
the shorter period, but only to the extent of the accrued right to purchase at
the date of such termination; otherwise, his rights under any then outstanding
Option shall terminate immediately. In the case of a Participant who is
permanently and totally disabled at the time of leaving the Company, the above
stated (3) month period shall be increased to one (1) year.

        3. BASIC TERM OF OPTION.

        Subject to the limitations contained elsewhere in this Agreement, this
Option shall remain open and exercisable for a period of 10 (10) years, through
and including March 20, 2005, after which this Option shall lapse and become
void.

        4. MANNER OF EXERCISE OF OPTION.

        (a) This Option shall be exercised in whole or in part by written
notice to the Company addressed to the President of the Company at such place
as the Company's executive offices may then be located, such notice, in
accordance with the attached exercise form, together with payment for the
Option Price for the number of Option Shares being exercised and stated
therein, to be delivered either personally or by registered or certified mail.
Such notice, if delivered by registered or certified mail, shall be deemed to
be received by the Company at the time of receipt, provided it is received by
the Company before the expiration of the Basic Term hereof. Such notice shall
state the number of Option Shares such Participant (or other person as may be
exercising this Option) elects to exercise under this Option (such number not
to exceed the maximum number of Exercisable Option Shares). Unless Participant
has been given notice by the Company that the Option Shares have been
registered pursuant to the Securities Act of 1933, as amended, such notice
shall contain a certificate substantially as follows:

         "I hereby represent and warrant to the Company that I am
         acquiring the shares pursuant to this Option for my own account for
         investment; that I am not acquiring such shares with a view to, or in
         connection with, any offering or distribution; and that I have no
         present intention of selling or otherwise disposing of any of such
         shares."

        (b) Manner of Payment. Payment for Option Shares purchased upon
exercising all or part of this Option shall be made in full at the time of
exercise, in cash, or, in the Company's discretion, in common stock of the
Company owned by the Participant, valued as of the close of business on the
immediately preceding business day, and such other forms of consideration
having a current value equal to the option price as may be suitable to the
Board, or in any combination of the foregoing. No Option Shares may be
delivered until full payment of the purchase price thereof has been made.

        5. RIGHTS AS A STOCKHOLDER.

        After receipt of the notice of exercise as provided in paragraph 4
above, the Company shall cause to be issued and delivered such certificates, in
such denominations as Participant may direct, representing the number of
fully-paid, nonassessable shares of common stock which the Participant is
entitled to receive, registered in the name of Participant, but Participant
shall have no right as a stockholder with respect to any such shares until the
issuance of such stock certificates, and no adjustment shall be made for cash
dividends or other rights for which the record date is prior to the time such
stock certificates are issued, except as provided herein. The Company agrees to
issue such stock certificates within thirty (30) business days after such
receipt of notice of the exercise of this Option, along with payment. Each
certificate shall be issued in the name of Participant so exercising this
Option, or in the name of Participant and his spouse as joint tenants, if
Participant should so request.

        6. RESTRICTIONS ON OPTION.

        (a) This Option shall not be transferred by Participant other than by
Will, or by the applicable laws of descent and distribution, or a qualified
domestic relations order as defined in the Code ("QUADRO"), and can be
exercised during his lifetime only by Participant, his guardian or legal
representative, or the QUADRO beneficiaries. This Option shall not be subject
to any claim of any creditor of Participant; shall not be subject to
attachment, garnishment or other legal or equitable process by or on behalf of
any such creditor; and shall not in anywise be liable for or subject to the
debts, contracts, liabilities, engagements or torts of Participant. This Option
shall not be pledged, hypothecated, or otherwise encumbered, and any attempt to
do so shall be void.

        (b) THERE CAN BE NO ASSURANCE THAT THE SHARES ISSUED PURSUANT TO THIS
OPTION WILL BE REGISTERED UNDER THE SECURITIES ACT OF 1933, OR THE APPLICABLE
SECURITIES LAWS OF ANY STATE. EACH STOCK CERTIFICATE SHALL CARRY SUCH
APPROPRIATE LEGEND, AND SUCH WRITTEN INSTRUCTIONS SHALL BE GIVEN TO THE
COMPANY'S TRANSFER AGENT, AS MAY BE DEEMED ADVISABLE BY COUNSEL TO THE COMPANY,
TO COMPLY WITH THE SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAW.
ACCORDINGLY, THE OWNER OF SUCH SHARES MAY BE REQUIRED TO HOLD THEM FOR AN
INDEFINITE PERIOD OF TIME.

        7. HOLDING PERIODS.

        (a) With respect to Participants who are also executive officers,
directors or ten percent shareholders of the Company, the Options Shares
received upon exercise of this Option shall not be sold or disposed of within
six (6) months from the date of this Agreement.

        (b) With respect to all Participants, the Option Shares received by the
Participant upon exercise of this Option shall not be sold or disposed of
within one (1) year after their acquisition by exercise of this Option, nor
within two (2) years from the granting of this Option. Should Participant
dispose of Option Shares received before the expiration of either of such
holding periods, such disposition shall be a "disqualifying disposition" of
an "incentive stock option" and any gain realized by Participant on such
disposition for federal income tax purposes will be taxable as ordinary income
in accordance with the Code.

        8. CAPITAL ADJUSTMENTS AND REORGANIZATIONS.

        (a) The Option Shares covered by this Option, and the Option Price,
shall be adjusted to reflect any stock dividend, stock split, share
combination, exchange of shares,





INCENTIVE STOCK OPTION AGREEMENT                                         PAGE 4
   5

recapitalization, merger, consolidation, separation, reorganization,
liquidation or the like, of or by the Company, in accordance with the Plan.

        (b) Nothing in this paragraph 8 shall in any way extend the time within
which this Option must be exercised as provided in Paragraph 3 above.

        9. DISSOLUTION OR MERGER.

        In the event that, prior to the delivery by the Company of all the
Option Shares in respect of which Options are granted, a merger or dissolution
in which the Company is not the surviving Corporation shall occur, or a
transfer of substantially all the assets of the Company shall occur:

        (a) If provision be made in writing in connection with such transaction
for the assumption and continuance of the Option hereby granted, or the
substitution for such Option of a new option covering the shares of the
successor corporation, with appropriate adjustment as to number and kind of
shares and prices, this Option, or the new option substituted therefore, as the
case may be, shall continue in the same manner and under the terms provided.

        (b) In the event provision is not made in such transaction for the
continuance and assumption of this Option or for the substitution of an option
covering the shares of the successor corporation, then Participant shall be
entitled within a reasonable period of time, prior to the effective date of any
such transaction, to purchase the full number of Exercisable Option Shares,
failing which purchase, any unexercised portion thereof shall be deemed
canceled as of such effective transaction date.

        10. WITHHOLDING TAX.

        Should the Company be required to withhold any tax pursuant to the
exercise of this Option by Participant, Participant agrees to make arrangements
satisfactory to the Board to ensure that the amount required to be withheld is
made available to the Company for timely payment. If agreeable to the Board,
Participant shall be allowed to deliver shares of the Company's common stock
previously owned by Participant, or Option Shares from the exercise of this
Option, for the payment of such withholding tax.

        11. CONTINUED EMPLOYMENT.

        By acceptance of this Option and in consideration thereof, and subject
to the qualifications and exceptions contained in Paragraph 2 above, this
Option may be exercised only while Participant remains in the continuous employ
of the Company, or one of its subsidiaries; provided, however, that this Option
does not confer upon Participant any right to continue in the employ of the
Company, or one of its subsidiaries, nor does it interfere in any way with the
right to terminate the employment of the Participant at any time.

        12. PIGGYBACK REGISTRATION RIGHTS

        (a) If, at any time from this date forward, the Company proposes to
file a registration statement relating to any of its common stock or other
securities under the Securities Act of 1933 (the "Securities Act"), and the
Option Shares are not then registered, the Company will promptly, but in any
event not less than thirty (30) days prior to the initial filing of such
registration statement, deliver written notice of such intention to the
Participant, setting forth the type of securities proposed to be registered,
the intended method of disposition, the maximum proposed offering price,
commissions and discounts in connection therewith and other relevant
information. If the Participant so requests within twenty (20) days after such
notification, the Company hereby agrees to use its best efforts to register the
Option Shares or any part thereof by inclusion in such registration statement
so that such Option Shares may be sold at such times and in such manner as the
Participant shall determine.

        (b) The Company shall not be required to register Option Shares under
the Securities Act or under any state securities law: (i) if the opinion of
counsel for both the Participant and the Company (or should they not agree, in
the opinion of another counsel experienced in securities law matters agreeable
to counsel for the Participant and for the Company), the proposed public
offering or transfer of the number of Option Shares, as to which registration
is requested, is exempt from the registration provisions of the Securities Act
and the securities laws of the state in which the Option Shares are to be sold
or transferred, or (ii) to the extent that in an underwritten public offering
by the Company, the managing underwriter in any way limits the Option Shares
that can be registered.

        (c) All costs and expenses in connection with the registration of any
Option Shares pursuant to the Participant's exercise of his "piggyback
registration rights," including federal and state registration and filing
fees, printing expenses (including such number of any preliminary prospectus
and the final prospectus as may reasonably be requested) and the fees and
disbursements of counsel and of independent accountants and other experts of
the Company shall be borne pro rata by the Company and the Participant;
provided, however, that the Company shall not be obligated to pay fees and
disbursements of counsel for the Participant or any underwriting commission or
discounts relating to the Option Shares.

        13. PLAN.

        The Option provided for in this Agreement is granted pursuant to the
Plan, as amended, which was adopted by the Board on March 6, 1989, and approved
by the Shareholders on May 22, 1989. The terms and provisions of the Plan are
incorporated by reference herein, and in case of any conflict between the terms
and conditions of this Agreement, and those of the Plan, those of the Plan
shall prevail and be controlling.

plural number, is used herein, the application of one shall include the

in person or by certified mail to the Company at its principal place of
business, to the attention of the President. All notices to the Participant or
other person or persons then entitled to exercise the Option, shall be
delivered to the Participant or such other person or persons at the
Participant's address below specified.

        16. APPLICATION.

individual or circumstance shall be invalid or unenforceable to any extent,
such provision shall be modified to the minimum extent necessary to make it or
its application valid and enforceable. The remainder of this Agreement, and the
application of such provision to other entities, persons or circumstances,
shall not be affected thereby, and shall be enforced to the greatest extent
permitted by law.
