(1) Consisting of, on an as converted basis, 4,362,053 shares of Common Stock (as defined below) of the Registrant reserved for issuance under the Sanifill, Inc. 1994 Long-term Incentive Plan, the Sanifill, Inc. 1989 Stock Option Plan (together, the "Sanifill Plans"), and the Warrant to Purchase 100,000 Shares of Common Stock of Sanifill, Inc. (the Sanifill "Warrant"). At the effective time of the Merger (as defined below), the Sanifill Plans and the Sanifill Warrant were assumed by the Registrant and each share of Sanifill, Inc. issuable under the Sanifill Plans and the Sanifill Warrant was converted into such number of shares of Common Stock of the Registrant as specified in the Merger Agreement (as defined below). (2) Not applicable. All filing fees payable in connection with the issuance of these securities were paid in connection with the filing of the Registrant's Form S-4 registration statement No. 333-08161 filed July 19, 1996. * Filed as a Post-effective Amendment on Form S-8 to such Form S-4 registration statement pursuant to the procedure described herein in the section captioned "Introductory Statement". 2 PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT INTRODUCTORY STATEMENT USA Waste Services, Inc. (the "Company" or the "Registrant") hereby amends its registration statement on Form S-4 (No. 333-08161) (the "Form S-4") by filing this Post-effective Amendment No. 1 thereto on Form S-8 ("Post- effective Amendment No. 1") relating to up to 4,362,053 shares of common stock, par value $.01 per share, of the Company ("Common Stock") issuable under the Sanifill, Inc. 1994 Long-term Incentive Plan and the Sanifill, Inc. 1989 Stock Option Plan (together, the "Sanifill Plans") and the Warrant to Purchase 100,000 Shares of Common Stock of Sanifill, Inc. (the "Sanifill Warrant"). All such shares of Common Stock were previously included in the Form S-4. Pursuant to an Agreement and Plan of Merger dated as of June 22, 1996 (the "Merger Agreement") among the Company, Quatro Acquisition Corp., a wholly owned subsidiary of the Company ("Quatro"), and Sanifill, Inc. ("Sanifill"), Quatro was merged with and into Sanifill on August 30, 1996 with an effective date as of September 3, 1996 (the "Merger"). Pursuant to the Merger, Sanifill became a wholly owned subsidiary of the Company, and the Company assumed the obligations under each outstanding stock option issued pursuant to the Sanifill Plans ("Sanifill Option") and under the Sanifill Warrant to purchase Sanifill common stock that remains unexpired and unexercised in whole or in part. As a result of the Merger, shares of Sanifill common stock are no longer issuable upon exercise of the Sanifill Options and Sanifill Warrant. Instead, in accordance with the exchange ratio set forth in the Merger Agreement, the Company has provided for the issuance of shares of Common Stock in lieu of the shares of Sanifill common stock reserved for issuance under the Sanifill Plans and Sanifill Warrant. Specifically, each Sanifill share issuable under the Sanifill Plans and Sanifill Warrant was converted into the right to receive from the Company 1.70 (the "Exchange Ratio") shares of Common Stock at a price per share of Common Stock equal to the exercise price determined pursuant to the Sanifill Option or Sanifill Warrant divided by the Exchange Ratio, and subject to the same terms and conditions as the Sanifill Option and Sanifill Warrant. The designation of Post-effective Amendment No. 1 as Registration No. 333-08161 denotes that Post-effective Amendment No. 1 relates only to the Common Stock issuable pursuant to the Sanifill Plans and Sanifill Warrant or upon the exercise of the stock options and warrants granted thereunder, respectively, and that this is the first post-effective amendment to the S-4 filed with respect to such shares. II-2 3 ITEM 3. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE.

ITEM 4. DESCRIPTION OF SECURITIES.

INTERESTS OF NAMED EXPERTS AND COUNSEL. The information required by Item 5 is not applicable to this registration statement. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation Law ("DGCL") provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, other than an action by or in the right of the corporation, by reason of the fact that he is or was a director, officer, employee or agent of the corporation or is or was serving at its request in such capacity in another corporation or business association, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner II-3 4 he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceedings, had no reasonable cause to believe his conduct was unlawful. With respect to actions by or in the right of the corporation, a person may not be indemnified if he has been adjudged to be liable to the corporation, except where, besides meeting the requirements described in the preceding sentence, the court in which such action was brought determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. To the extent that a director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to above, he shall be indemnified against expenses, including attorneys' fees, actually and reasonably incurred by him in connection therewith. A corporation shall have the power to purchase insurance on behalf of the persons referred to above against any liability asserted against them and incurred by them in such capacities referred to whether or not the corporation would have the power to indemnify them against such liability. Section 102(b)(7) of the DGCL provides that the certificate of incorporation of a corporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director for (i) any breach of the director's duty of loyalty to the corporation or its shareholders, (ii) acts or omissions not in good faith or which involved intentional misconduct or a knowing violation of law, (iii) unlawful dividend payment or stock purchase or redemption under Section 174 of the DGCL, (iv) any transaction from which the director derived an improper personal benefit, or (v) any act or omission occurring prior to the date when such provision becomes effective. The Registrant's Certificate of Incorporation provides that (i) the Registrant shall indemnify, and advance litigation expenses to, its officers, directors, employees and agents to the fullest extent permitted by the DGCL and all other laws of the State of Delaware, (ii) to the fullest extent that the DGCL permits the limitation or elimination of the liability of directors, no director of the Registrant shall be personally liable to the Registrant or its shareholders for monetary damages for breach of fiduciary duty as a director, (iii) no amendment to or repeal of the provision of the Certificate of Incorporation described in clause (ii) shall apply to or have any effect on the liability or alleged liability of any director of the Registrant for or with respect to any acts or omission of such director occurring prior to the time of such amendment or repeal and (iv) any amendment to the DGCL which further limits or eliminates the liability of directors shall be fully applicable to the Registrant's directors. The Registrant has indemnification agreements with its directors. ITEM 8. EXHIBITS.

ITEM 9. UNDERTAKINGS. (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the II-5 6 maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. II-6 7 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Dallas, State of Texas, on this 5th day of September, 1996.

Ladies and Gentlemen:

         We have acted as counsel to USA Waste Services, Inc., a Delaware
corporation (the "Company") in connection with the Company's Post-effective
Amendment No. 1 on Form S-8 to the registration statement on Form S-4
(Registration No. 333-08161) (the "Registration Statement"), relating to the
registration under the Securities Act of 1933, as amended, of the issuance of
4,362,053 shares of common stock, par value $.01 per share (the "Common
Stock"), of the Company (the "Shares") issuable upon the exercise of options
(the "Options") granted pursuant to the Sanifill Inc. 1994 Long-term Incentive
Plan and the Sanifill, Inc. 1989 Stock Option Plan (together, the "Plans") and
the Warrant to Purchase 100,000 Shares of Common Stock of Sanifill, Inc. (the
"Warrant").

         As the basis for the opinions hereinafter expressed, we have examined
such corporate records and documents, certificates of corporate and public
officials and such other instruments as we have deemed necessary for the
purposes of the opinions contained herein.  As to all matters of fact material
to such opinions, we have relied upon the representations of officers of the
Company.  We have assumed the genuineness of all signatures, the authenticity
of all documents submitted to us as originals, and the conformity with the
original documents of all documents submitted to us as copies.

         Based upon the foregoing and having due regard for such legal
considerations as we deem relevant, we are of the opinion that the Shares to be
issued upon proper exercise of the Options and the Warrant have been duly
authorized, and that the Shares, when issued upon proper exercise of the
Options and the Warrant, will be validly issued, fully paid and nonassessable.

                         1994 LONG-TERM INCENTIVE PLAN

         1.      Purpose.  The purpose of this 1994 Long-Term Incentive Plan
(the "Plan") of Sanifill, Inc., a Delaware corporation (the "Company"), is to
advance the interests of the Company and its stockholders by providing a means
to attract, retain, and reward executive officers and other key employees of
the Company and its subsidiaries (including consultants providing services of
substantial value) and to enable such persons to acquire or increase a
proprietary interest in the Company, thereby promoting a closer identity of
interests between such persons and the Company's stockholders.

         2.      Definitions.  The definitions of awards under the Plan,
including Options, SARs (including Limited SARs), Restricted Stock, Deferred
Stock, Stock granted as a bonus or in lieu of other awards, Dividend
Equivalents, and Other Stock-Based Awards, are set forth in Section 6 of the
Plan.  Such awards, together with any other right or interest granted to a
Participant under the Plan, are termed "Awards."  For purposes of the Plan, the
following additional terms shall be defined as set forth below:

                 (a)      "Award Agreement" means any written agreement,
         contract, or other instrument or document evidencing an Award.

                 (b)      "Beneficiary" shall mean the person, persons, trust,
         or trusts which have been designated by a Participant in his or her
         most recent written beneficiary designation filed with the Committee
         to receive the benefits specified under this Plan upon such
         Participant's death or, if there is no designated Beneficiary or
         surviving designated Beneficiary, then the person, persons, trust, or
         trusts entitled by will or the laws of descent and distribution to
         receive such benefits.

                 (c)      "Board" means the Board of Directors of the Company.

         amended from time to time.  References to any provision of the Code
         shall be deemed to include regulations thereunder and successor
         provisions and regulations thereto.

                 (e)      "Committee" means the Compensation Committee of the
         Board, or such other Board committee as may be designated by the Board
         to administer the Plan; provided, however, that the Committee shall at

         "disinterested person" within the meaning of Rule 16b-3 under the
         Exchange Act.





   2



                 (f)      "Exchange Act" means the Securities Exchange Act of

         the Exchange Act shall be deemed to include rules thereunder and
         successor provisions and rules thereto.

                 (g)      "Fair Market Value" means, with respect to Stock,
         Awards, or other property, the fair market value of such Stock,
         Awards, or other property determined by such methods or procedures as
         shall be established from time to time by the Committee.  Unless
         otherwise determined by the Committee, the Fair Market Value of Stock
         as of any given date shall mean the closing price of the Stock on the
         date on which such value is to be determined or, if there was no trade
         on such date, on the nearest day preceding such date on which there
         was a trade, as reported in the table entitled "New York Stock
         Exchange Composite Transactions" contained in The Wall Street Journal
         or an equivalent successor table.

                 (h)      "ISO" means any Option intended to be and designated

         eligible under Section 5 hereof, has been granted an Award under the

         in effect and applicable to the Plan and Participants, promulgated by
         the Securities and Exchange Commission under Section 16 of the
         Exchange Act.

                 (k)      "Stock" means the Common Stock, $.01 par value, of
         the Company and such other securities as may be substituted for Stock
         or such other securities pursuant to Section 4.

         3.      Administration.

         (a)     Authority of the Committee.  The Plan shall be administered by
the Committee.  The Committee shall have full and final authority to take the
following actions, in each case subject to and consistent with the provisions
of the Plan:

                 (i)      to select Participants to whom Awards may be granted;

                 (ii)     to determine the type or types of Awards to be
         granted to each Participant;

                 (iii)    to determine the number of Awards to be granted, the
         number of shares of Stock to which an Award will relate, the terms and
         conditions of any Award granted under the Plan (including, but not
         limited to, any exercise price, grant price, or purchase price, any
         restriction or condition, any schedule for lapse of restrictions or
         conditions relating to transferability or forfeiture, exercisability,
         or settlement of an Award, and waivers or accelerations thereof, and
         waivers of or modifications to performance conditions relating to





   3


         an Award, based in each case on such considerations as the Committee
         shall determine), and all other matters to be determined in connection
         with an Award;

                 (iv)     to determine whether, to what extent, and under what
         circumstances an Award may be settled, or the exercise price of an
         Award may be paid, in cash, Stock, other Awards, or other property, or
         an Award may be cancelled, forfeited, or surrendered;

                 (v)      to determine whether, to what extent, and under what
         circumstances cash, Stock, other Awards, or other property payable
         with respect to an Award will be deferred either automatically, at the
         election of the Committee, or at the election of the Participant;

                 (vi)     to prescribe the form of each Award Agreement, which
         need not be identical for each Participant;

                 (vii)    to adopt, amend, suspend, waive, and rescind such
         rules and regulations and appoint such agents as the Committee may
         deem necessary or advisable to administer the Plan;

                 (viii)   to correct any defect or supply any omission or
         reconcile any inconsistency in the Plan and to construe and interpret
         the Plan and any Award, rules and regulations, Award Agreement, or
         other instrument hereunder; and

                 (ix)     to make all other decisions and determinations as may
         be required under the terms of the Plan or as the Committee may deem
         necessary or advisable for the administration of the Plan.

         (b)     Manner of Exercise of Committee Authority.  Unless authority
is specifically reserved to the Board under the terms of the Plan, the
Company's Certificate of Incorporation or Bylaws, or applicable law, the
Committee shall have sole discretion in exercising authority under the Plan.
Any action of the Committee with respect to the Plan shall be final,
conclusive, and binding on all persons, including the Company, subsidiaries of
the Company, Participants, any person claiming any rights under the Plan from
or through any Participant, and stockholders.  The express grant of any
specific power to the Committee, and the taking of any action by the Committee,
shall not be construed as limiting any power or authority of the Committee.
The Committee may delegate to officers or managers of the Company or any
subsidiary of the Company the authority, subject to such terms as the Committee
shall determine, to perform administrative functions and, with respect to
Participants not subject to Section 16 of the Exchange Act, to perform such
other functions as the Committee may determine, to the extent permitted under
Rule 16b-3 and applicable law.

         (c)     Limitation of Liability.  Each member of the Committee shall
be entitled to, in good faith, rely or act upon any report or other information
furnished to him by any officer or other employee of the Company or any
subsidiary, the Company's independent certified public accountants, or any
executive compensation consultant, legal counsel, or other professional
retained





   4


by the Company to assist in the administration of the Plan.  No member of the
Committee, nor any officer or employee of the Company acting on behalf of the
Committee, shall be personally liable for any action, determination, or
interpretation taken or made in good faith with respect to the Plan, and all
members of the Committee and any officer or employee of the Company acting on
their behalf shall, to the extent permitted by law, be fully indemnified and
protected by the Company with respect to any such action, determination, or
interpretation.

         4.      Stock Subject to Plan.

         (a)     Amount of Stock Reserved.  No Award may be granted to a
Participant hereunder if the number of shares of Stock subject to such Award,
when aggregated with (i) the number of shares subject to then-outstanding
Awards under the Plan and (ii) the number of shares subject to then-outstanding
options granted under the Company's 1989 Stock Option Plan, as amended (the
"1989 Plan"), would exceed 14 percent of the number of shares of Stock of the
Company then-outstanding; provided, however, that the number of shares that
may be delivered upon exercise of ISOs shall not exceed 500,000 under the Plan,
and provided further, that the number of shares that may be delivered as
Restricted Stock and Deferred Stock shall not in the aggregate exceed 500,000
under the Plan.  If an Award or a 1989 Plan option is forfeited or expires or
an Award is settled in cash or otherwise terminates without delivery of shares
to the Participant, such number of shares shall not be deemed to have been
delivered for purposes of this Section 4(a) and the shares subject thereto
shall be available for further grants in such calendar year or, if the
previously existing Award was Restricted or Deferred Stock, such shares shall
be available again for grants under the limitation applicable to Restricted and
Deferred Stock; provided, however, that, if any shares could not again be
available for Awards to a Participant who is subject to Section 16 of the
Exchange Act under applicable share counting requirements of Rule 16b-3, such
shares shall be available exclusively for Awards to Participants who are not
subject to Section 16.  If an Award valued by reference to Stock may only be
settled in cash, the number of shares to which such Award relates shall be
deemed to be Stock subject to such Award for purposes of this Section 4(a).
Any shares of Stock delivered pursuant to an Award may consist, in whole or in
part, of authorized and unissued shares or treasury shares.

         (b)     Annual Per-Participant Limitations.  During any calendar year,
no Participant may be granted Options and other Awards under the Plan that may
be settled by delivery of more than 350,000 shares of Stock.  In addition, with
respect to Awards that may be settled in cash, no Participant may be paid
during any calendar year cash amounts relating to such Awards that exceed the
greater of the Fair Market Value of the number of shares of Stock set forth in
the preceding sentence at the date of grant or the date of settlement of Award.
This provision sets forth two separate limitations, so that awards that may be
settled solely by delivery of Stock will not operate to reduce the amount of
cash-only Awards, and vice versa; nevertheless, Awards that may be settled in
Stock or cash must not exceed either limitation.

         (c)     Adjustments.  In the event of any dividend or other
distribution (whether in the form of cash, Stock, or other property),
recapitalization, forward or reverse split, reorganization, merger,
consolidation, spin-off, combination, repurchase, or share exchange, or other
similar corporate





   5
transaction or event, affects the Stock such that an adjustment is appropriate
in order to prevent dilution or enlargement of the rights of Participants under
the Plan, then the Committee shall, in such manner as it may deem equitable,
adjust any or all of (i) the number and kind of shares of Stock deemed to be
available thereafter for grants of Awards under Section 4(a) (including with
respect to the limitations relating to ISOs and to Restricted and Deferred
Stock), (ii) the number and kind of shares of Stock that may be delivered or
deliverable in respect of outstanding Awards, (iii) the number of shares with
respect to which Awards may be granted to a given Participant in the specified
period as set forth in Section 4(b), and (iv) the exercise price, grant price,
or purchase price relating to any Award (or, if deemed appropriate, the
Committee may make provision for a cash payment with respect to any outstanding
Award).  In addition, the Committee is authorized to make adjustments in the
terms and conditions of, and the criteria included in, Awards in recognition of
unusual or nonrecurring events (including, without limitation, events described
in the preceding sentence) affecting the Company or any subsidiary or the
financial statements of the Company or any subsidiary, or in response to
changes in applicable laws, regulations, or accounting principles.  The
foregoing notwithstanding, no adjustments shall be authorized under this
Section 4(c) with respect to ISOs or SARs in tandem therewith to the extent
that such authority would cause the Plan to violate Section 422(b)(1) of the
Code, and no such adjustment shall be authorized with respect to Options or
other Awards granted in accordance with Section 7(f) hereof to the extent that
such authority would cause such Options or other Awards to fail to qualify as
"performance-based compensation" under Section 162(m)(4)(C) of the Code and
regulations thereunder (including Proposed Regulation 1.162-27(e)(2)).

         5.      Eligibility.  Executive officers and other key employees of
the Company and its subsidiaries, including any director or officer who is also
such an employee, and persons who provide consulting or other services to the
Company deemed by the Committee to be of substantial value to the Company, are
eligible to be granted Awards under the Plan.  In addition, a person who has
been offered employment by the Company or its subsidiaries is eligible to be
granted an Award under the Plan, provided that such Award shall be cancelled if
such person fails to commence such employment, and no payment of value may be
made in connection with such Award until such person has commenced such
employment.  The foregoing notwithstanding, directors of the Company who are
not employees and members of the Committee shall not be eligible to be granted
Awards under the Plan.

         6.      Specific Terms of Awards.

         (a)     General.  Awards may be granted on the terms and conditions
set forth in this Section 6.  In addition, the Committee may impose on any
Award or the exercise thereof, at the date of grant or thereafter (subject to
Section 8(e)), such additional terms and conditions, not inconsistent with the
provisions of the Plan, as the Committee shall determine, including terms
requiring forfeiture of Awards in the event of termination of employment or
service of the Participant.  Except as provided in Sections 6(f), 6(h), or
7(a), or to the extent required to comply with requirements of the Delaware
General Corporation Law that lawful consideration be paid for Stock, only
services may be required as consideration for the grant (but not the exercise)
of any Award.





   6



         (b)     Options.  The Committee is authorized to grant Options to
Participants (including "reload" options automatically granted to offset
specified exercises of options) on the following terms and conditions:

                 (i)      Exercise Price.  The exercise price per share of
         Stock purchasable under an Option shall be determined by the
         Committee; provided, however, that, except as provided in Section
         7(a), such exercise price shall be not less than the Fair Market Value
         of a share on the date of grant of such Option.

                 (ii)     Time and Method of Exercise.  The Committee shall
         determine the time or times at which an Option may be exercised in
         whole or in part, the methods by which such exercise price may be paid
         or deemed to be paid, the form of such payment, including, without
         limitation, cash, Stock, or other Awards or awards granted under other
         Company plans, or other property (including notes or other contractual
         obligations of Participants to make payment on a deferred basis, such
         as through "cashless exercise" arrangements, to the extent permitted
         by applicable law), and the methods by which Stock will be delivered
         or deemed to be delivered to Participants.

                 (iii)    ISOs.  The terms of any ISO granted under the Plan
         shall comply in all respects with the provisions of Section 422 of the
         Code, including but not limited to the requirement that no ISO shall
         be granted more than ten years after the effective date of the Plan.
         Anything in the Plan to the contrary notwithstanding, no term of the
         Plan relating to ISOs shall be interpreted, amended, or altered, nor
         shall any discretion or authority granted under the Plan be exercised,
         so as to disqualify either the Plan or any ISO under Section 422 of
         the Code.

         (c)     Stock Appreciation Rights.  The Committee is authorized to
grant SARs to Participants on the following terms and conditions:

                 (i)      Right to Payment.  An SAR shall confer on the
         Participant to whom it is granted a right to receive, upon exercise
         thereof, the excess of (A) the Fair Market Value of one share of Stock
         on the date of exercise (or, if the committee shall so determine in
         the case of any such right other than one related to an ISO, the Fair
         Market Value of one share at any time during a specified period before
         or after the date of exercise), over (B) the grant price of the SAR as
         determined by the Committee as of the date of grant of the SAR, which,
         except as provided in Section 7(a), shall be not less than the Fair
         Market Value of one share of Stock on the date of grant.

                 (ii)     Other Terms.  The Committee shall determine the time
         or times at which an SAR may be exercised in whole or in part, the
         method of exercise, method of settlement, form of consideration
         payable in settlement, method by which Stock will be delivered or
         deemed to be delivered to Participants, whether or not an SAR shall be
         in tandem with any  other Award, and other terms and conditions of any
         SAR.  Limited SARs that may only be





   7


         exercised upon the occurrence of a change in control (as such term may
         be defined by the Committee) may be granted on such terms, not
         inconsistent with this Section 6(c), as the Committee may determine.
         Limited SARs may be either freestanding or in tandem with other
         Awards.

         (d)     Restricted Stock.  The Committee is authorized to grant
Restricted Stock to Participants on the following terms and conditions:

                 (i)      Grant and Restrictions.  Restricted Stock shall be
         subject to such restrictions on transferability and other
         restrictions, if any, as the Committee may impose, which restrictions
         may lapse separately or in combination at such times, under such
         circumstances, in such installments, or otherwise, as the Committee
         may determine.  Except to the extent restricted under the terms of the
         Plan and any Award Agreement relating to the Restricted Stock, a
         Participant granted Restricted Stock shall have all of the rights of a
         stockholder including, without limitation, the right to vote
         Restricted Stock or the right to receive dividends thereon.

                 (ii)     Forfeiture.  Except as otherwise determined by the
         Committee, upon termination of employment or service (as determined
         under criteria established by the Committee) during the applicable
         restriction period, Restricted Stock that is at that time subject to
         restrictions shall be forfeited and reacquired by the Company;
         provided, however, that the Committee may provide, by rule or
         regulation or in any Award Agreement, or may determine in any
         individual case, that restrictions or forfeiture conditions relating
         to Restricted Stock will be waived in whole or in part in the event of
         termination resulting from specified causes.

                 (iii)    Certificates for Stock.  Restricted Stock granted
         under the Plan may be evidenced in such manner as the Committee shall
         determine.  If certificates representing Restricted Stock are
         registered in the name of the Participant, such certificates shall
         bear an appropriate legend referring to the terms, conditions, and
         restrictions applicable to such Restricted Stock, the Company shall
         retain physical possession of the certificate, and the Participant
         shall have delivered a stock power to the Company, endorsed in blank,
         relating to the Restricted Stock.

                 (iv)     Dividends.  Dividends paid on Restricted Stock shall
         be either paid at the dividend payment date in cash or in shares of
         unrestricted Stock having a Fair Market Value equal to the amount of
         such dividends, or the payment of such dividends shall be deferred
         and/or the amount or value thereof automatically reinvested in
         additional Restricted Stock, other Awards, or other investment
         vehicles, as the Committee shall determine or permit the Participant
         to elect.  Stock distributed in connection with a Stock split or Stock
         dividend, and other property distributed as a dividend, shall be
         subject to restrictions and a risk of forfeiture to the same extent as
         the Restricted Stock with respect to which such Stock or other
         property has been distributed.





   8


         (e)     Deferred Stock.  The Committee is authorized to grant Deferred
Stock to Participants, subject to the following terms and conditions:

                 (i)      Award and Restrictions.  Delivery of Stock will occur
         upon expiration of the deferral period specified for an Award of
         Deferred Stock by the Committee (or, if permitted by the Committee, as
         elected by the Participant).  In addition, Deferred Stock shall be
         subject to such restrictions as the Committee may impose, if any,
         which restrictions may lapse at the expiration of the deferral period
         or at earlier specified times, separately or in combination, in
         installments, or otherwise, as the Committee may determine.

                 (ii)     Forfeiture.  Except as otherwise determined by the
         Committee, upon termination of employment or service (as determined
         under criteria established by the Committee) during the applicable
         deferral period or portion thereof to which forfeiture conditions
         apply (as provided in the Award Agreement evidencing the Deferred
         Stock), all Deferred Stock that is at that time subject to deferral
         (other than a deferral at the election of the Participant) shall be
         forfeited; provided, however, that the Committee may provide, by rule
         or regulation or in any Award Agreement, or may determine in any
         individual case, that restrictions or forfeiture conditions relating
         to Deferred Stock will be waived in whole or in part in the event of
         termination resulting from specified causes.

         (f)     Bonus Stock and Awards in Lieu of Cash Obligations.  The
Committee is authorized to grant Stock as a bonus, or to grant Stock or other
Awards in lieu of Company obligations to pay cash under other plans or
compensatory arrangements, provided that, in the case of Participants subject
to Section 16 of the Exchange Act, such cash amounts are determined under such
other plans in a manner that complies with applicable requirements of Rule
16b-3 so that the acquisition of Stock or Awards hereunder shall be exempt from
Section 16(b) liability.  Stock or Awards granted hereunder shall be subject to
such other terms as shall be determined by the Committee.

         (g)     Dividend Equivalents.  The Committee is authorized to grant
Dividend Equivalents to a Participant, entitling the Participant to receive
cash, Stock, other Awards, or other property equal in value to dividends paid
with respect to a specified number of shares of Stock, or other periodic
payments.  Dividend Equivalents may be awarded on a free-standing basis or in
connection with another Award.  The Committee may provide that Dividend
Equivalents shall be paid or distributed when accrued or shall be deemed to
have been reinvested in additional Stock, Awards, or other investment vehicles
as the Committee may specify.

         (h)     Other Stock-Based Awards.  The Committee is authorized,
subject to limitations under applicable law, to grant to Participants such
other Awards that may be denominated or payable in, valued in whole or in part
by reference to, or otherwise based on, or related to, Stock, as deemed by the
Committee to be consistent with the purposes of the Plan, including, without
limitation, convertible or exchangeable debt securities, other rights
convertible or exchangeable into Stock, purchase rights for Stock, Awards with
value and payment contingent upon performance of the Company or any other
factors designated by the Committee, and Awards valued by reference to the





   9


book value of Stock or the value of securities of or the performance of
specified subsidiaries.  The Committee shall determine the terms and conditions
of such Awards.  Stock delivered pursuant to an Award in the nature of a
purchase right granted under this Section 6(h) shall be purchased for such
consideration, paid for at such times, by such methods, and in such forms,
including, without limitation, cash, Stock, other Awards, or other property, as
the Committee shall determine.  Cash awards, as an element of or supplement to
any other Award under the Plan, shall also be authorized pursuant to this
Section 6(h).

         7.      Certain Provisions Applicable to Awards.

         (a)     Stand-Alone, Additional, Tandem, and Substitute Awards.
Awards granted under the Plan may, in the discretion of the Committee, be
granted either alone or in addition to, in tandem with, or in substitution for,
any other Award granted under the Plan or any award granted under any other
plan of the Company, any subsidiary, or any business entity to be acquired by
the Company or a subsidiary, or any other right of a Participant to receive
payment from the Company or any subsidiary.  Awards granted in addition to or
in tandem with other Awards or awards may be granted either as of the same time
as or a different time from the grant of such other Awards or awards.  The per
share exercise price of any Option, grant price of any SAR, or purchase price
of any other Award conferring a right to purchase Stock:

                 (i)      Granted in substitution for an outstanding Award or
         award shall be not less than the lesser of the Fair Market Value of a
         share of Stock at the date such substitute Award is granted or such
         Fair Market Value at that date reduced to reflect the Fair Market
         Value at that date of the Award or award required to be surrendered by
         the Participant as a condition to receipt of the substitute Award; or

                 (ii)     Retroactively granted in tandem with an outstanding
         Award or award shall be not less than the lesser of the Fair Market
         Value of a share of Stock at the date of grant of the later Award or
         at the date of grant of the earlier Award or award.

         (b)     Term of Awards.  The term of each Award shall be for such
period as may be determined by the Committee; provided, however, that in no
event shall the term of any ISO or an SAR granted in tandem therewith exceed a
period of ten years from the date of its grant (or such shorter period as may
be applicable under Section 422 of the Code).

         (c)     Form of Payment Under Awards.  Subject to the terms of the
Plan and any applicable Award Agreement, payments to be made by the Company or
a subsidiary upon the grant or exercise of an Award may be made in such forms
as the Committee shall determine, including, without limitation, cash, Stock,
other Awards, or other property, and may be made in a single payment or
transfer, in installments, or on a deferred basis.  Such payments may include,
without limitation, provisions for the payment or crediting of reasonable
interest on installment or deferred payments or the grant or crediting of
Dividend Equivalents in respect of installment or deferred payments denominated
in Stock.





   10



         (d)     Rule 16b-3 Compliance.

                 (i)      Six-Month Holding Period.  Unless a Participant could
         otherwise exercise a derivative security or dispose of Stock delivered
         upon exercise of a derivative security granted under the Plan without
         incurring liability under Section 16(b) of the Exchange Act, (i) Stock
         delivered under the Plan other than upon exercise or conversion of a
         derivative security granted under the Plan shall be held for at least
         six months from the date of acquisition, and (ii), with respect to a
         derivative security granted under the Plan, at least six months shall
         elapse from the date of acquisition of the derivative security to the
         date of disposition of the derivative security (other than upon
         exercise or conversion) or its underlying equity security.

                 (ii)     Nontransferability.  Awards which constitute
         derivative securities (including any Option, SAR, Limited SAR, or
         similar right) under the general definition set forth in Rule
         16a-1(c)(3)(i) under the Exchange Act shall not be transferable by a
         Participant except by will or the laws of descent and distribution (or
         pursuant to a Beneficiary designation) and, in the case of any Option
         or SAR, shall be exercisable during the lifetime of a Participant only
         by such Participant or his guardian or legal representative.

                 (iii)    Reformation To Comply with Exchange Act Rules.  It is
         the intent of the Company that this Plan comply in all respects with
         applicable provisions of Rule 16b-3 or Rule 16a-1(c)(3) under the
         Exchange Act in connection with any grant of Awards to or other
         transaction by a Participant who is subject to Section 16 of the
         Exchange Act (except for transactions exempted under alternative
         Exchange Act Rules or acknowledged in writing to be non-exempt by such
         Participant).  Accordingly, if any provision of this Plan or any Award
         Agreement relating to an Award does not comply with the requirements
         of Rule 16b-3 or Rule 16a-1(c)(3) as then applicable to any such
         transaction, such provision will be construed or deemed amended to the
         extent necessary to conform to the applicable requirements of Rule
         16b-3 or Rule 16a-1(c)(3) so that such Participant shall avoid
         liability under Section 16(b).  In addition, other provisions of the
         Plan notwithstanding, the exercise price of any Award carrying a right
         to exercise granted to a Participant subject to Section 16 of the
         Exchange Act shall be not less than 50% of the Fair Market Value of
         Stock as of the date such Award is granted if such pricing limitation
         is required under Rule 16b-3 at the time of such grant.

         (e)     Loan Provisions.  With the consent of the Committee, and
subject at all times to, and only to the extent, if any, and in accordance
with, laws and regulations and other binding obligations or provisions
applicable to the Company, the Company may make, guarantee, or arrange for a
loan or loans to a Participant with respect to the exercise of any Option or
other payment in connection with any Award, including the payment by a
Participant of any or all federal, state, or local income or other taxes due in
connection with any Award.  Subject to such limitations, the Committee shall
have full authority to decide whether to make a loan or loans hereunder and to
determine the amount, terms, and provisions of any such loan or loans,
including the interest rate to be charged in respect





   11
of any such loan or loans, whether the loan or loans are to be with or without
recourse against the borrower, the terms on which the loan is to be repaid and
conditions, if any, under which the loan or loans may be forgiven.

         (f)     Performance-Based Awards to "Covered Employees".  Other
provisions of the Plan notwithstanding, the provisions of this Section 7(f)
shall apply to any Award the exercisability or settlement of which is subject
to the achievement of performance conditions (other than an Option or SAR
granted with an exercise or base price at least equal to 100% of Fair Market
Value of Stock on the date of grant) if such Award is granted to a person who,
at the time of grant, is a "covered employee."  The definition of "covered
employee," and other terms used in this Section 7(f), shall be interpreted in a
manner consistent with Section 162(m) of the Code and regulations thereunder
(including Proposed Regulation 1.162-27).  The performance objectives for an
Award subject to this Section 7(f) shall consist of one or more business
criteria and a targeted level or levels of performance with respect to such
criteria, as specified by the Committee but subject to this Section 7(f).
Performance objectives shall be objective and shall otherwise meet the
requirements of Section 162(m)(4)(C) of the Code and regulations thereunder
(including Proposed Regulation 1.162-27(e)(2)).  The following business
criteria shall be used by the Committee in connection with a performance
objective:

                 (1)      Annual earnings before payment of taxes and interest;

                 (2)      Annual earnings per share;

                 (3)      Annual return on common equity; and/or

                 (4)      Common Stock price appreciation.

Achievement of performance objectives shall be measured over a period of years,
as specified by the Committee.  No business criteria other than those named
above may be used in establishing the performance objective for an Award to a
covered employee.  For each such Award relating to a covered employee, the
Committee shall establish the targeted level or levels of performance for each
business criteria.  Performance objectives may differ for Awards under this
Section 7(f) to different covered employees.  The Committee may determine that
an Award under this Section 7(f) shall be payable upon achievement of any one
of the performance objectives or may require that two or more of the
performance objectives must be achieved in order for an Award to be payable.
The Committee may, in its discretion, reduce the amount of a payout otherwise
to be made in connection with an Award under this Section 7(f), but may not
exercise discretion to increase such amount, and the Committee may consider
other performance criteria in exercising such discretion.  All determinations
by the Committee as to the achievement of performance objectives shall be made
in writing.  The Committee may not delegate any responsibility under this
Section 7(f).





   12
         8.      General Provisions.

         (a)     Compliance with Legal and Exchange Requirements.  The Company
shall not be obligated to deliver Stock upon the exercise or settlement of any
Award or take other actions under the Plan until the Company shall have
determined that applicable federal and state laws, rules, and regulations have
been complied with and such approvals of any regulatory or governmental agency
have been obtained and contractual obligations to which the Award may be
subject have been satisfied.  The Company, in its discretion, may postpone the
issuance or delivery of Stock under any Award until completion of such stock
exchange listing or registration or qualification of such Stock or other
required action under any federal or state law, rule, or regulation as the
Company may consider appropriate, and may require any Participant to make such
representations and furnish such information as it may consider appropriate in
connection with the issuance or delivery of Stock under the Plan.

         (b)     Nontransferability.  In addition to the restrictions on
transferability set forth in Section 7(d)(ii) (which apply to all Participants
whether or not they are otherwise subject to Section 16 under the Exchange
Act), Awards and other rights of Participants under the Plan may not be
transferred to third parties, pledged, mortgaged, hypothecated, or otherwise
encumbered, and shall not be subject to claims of creditors.

         (c)     No Right to Continued Employment or Service.  Neither the Plan
nor any action taken hereunder shall be construed as giving any employee or
person providing consulting or other services the right to be retained in the
employ or service of the Company or any of its subsidiaries, nor shall it
interfere in any way with the right of the Company or any of its subsidiaries
to terminate any employee's employment or terminate any contract with a person
providing consulting or other services at any time.

         (d)     Taxes.  The Company or any subsidiary is authorized to
withhold from any Award granted or to be settled, any payment relating to an
Award under the Plan, including from a distribution of Stock, or any payroll or
other payment to a Participant, amounts of withholding and other taxes due or
potentially payable in connection with any transaction involving an Award, and
to take such other action as the Committee may deem advisable to enable the
Company and Participants to satisfy obligations for the payment of withholding
taxes and other tax obligations relating to any Award.  This authority shall
include authority to withhold or receive Stock or other property and to make
cash payments in respect thereof in satisfaction of a Participant's tax
obligations.

         (e)     Changes to the Plan and Awards.  The Board may amend, alter,
suspend, discontinue, or terminate the Plan or the Committee's authority to
grant Awards under the Plan without the consent of stockholders or
Participants, except that any such action shall be subject to the approval of
the Company's stockholders at or before the next annual meeting of stockholders
for which the record date is after such Board action if such stockholder
approval is required by any federal or state law or regulation or the rules of
any stock exchange or automated quotation system on which the





   13


Stock may then be listed or quoted, and the Board may otherwise, in its
discretion, determine to submit other such changes to the Plan to stockholders
for approval; provided, however, that, without the consent of an affected
Participant, no such action may materially impair the rights of such
Participant under any Award theretofore granted to him.  The Committee may
waive any conditions or rights under, or amend, alter, suspend, discontinue, or
terminate, any Award theretofore granted and any Award Agreement relating
thereto; provided, however, that, without the consent of an affected
Participant, no such action may materially impair the rights of such
Participant under such Award.

         (f)     No Rights to Awards; No Stockholder Rights.  No Participant,
employee, or other person shall have any claim to be granted any Award under
the Plan, and there is no obligation for uniformity of treatment of
Participants, employees, and other persons.  No Award shall confer on any
Participant any of the rights of a stockholder of the Company unless and until
Stock is duly issued or transferred and delivered to the Participant in
accordance with the terms of the Award.

         (g)     Unfunded Status of Awards; Creation of Trusts.  The Plan is
intended to constitute an "unfunded" plan for incentive and deferred
compensation.  With respect to any payments not yet made to a Participant
pursuant to an Award, nothing contained in the Plan or any Award shall give any
such Participant any rights that are greater than those of a general creditor
of the Company; provided, however, that the Committee may authorize the
creation of trusts or make other arrangements to meet the Company's obligations
under the Plan to deliver cash, Stock, other Awards, or other property pursuant
to any Award, which trusts or other arrangements shall be consistent with the
"unfunded" status of the Plan unless the Committee otherwise determines with
the consent of each affected Participant.

         (h)     Nonexclusivity of the Plan.  Neither the adoption of the Plan
by the Board nor its submission to the stockholders of the Company for approval
shall be construed as creating any limitations on the power of the Board to
adopt such other incentive arrangements as it may deem desirable, including,
without limitation, the granting of stock options otherwise than under the
Plan, and such arrangements may be either applicable generally or only in
specific cases.

         (i)     No Fractional Shares.  No fractional shares of Stock shall be
issued or delivered pursuant to the Plan or any Award.  The Committee shall
determine whether cash, other Awards, or other property shall be issued or paid
in lieu of such fractional shares or whether such fractional shares or any
rights thereto shall be forfeited or otherwise eliminated.

         (j)     Compliance with Code Section 162(m).  It is the intent of the
Company that Options and other Awards subject to the performance objectives
specified under Section 7(f) granted under the Plan to persons who are "covered
employees" within the meaning of Code Section 162(m) and regulations thereunder
(including Proposed Regulation 1.162-27(c)(2)) shall constitute "qualified
performance-based compensation" within the meaning of Code Section 162(m) and
regulations thereunder (including Proposed Regulation 1.162-27(e), and subject
to the transition rules under Proposed Regulation 1.162-27(h)(2)) thereunder.
Accordingly, if any provision of the Plan or any





   14


Award Agreement relating to such an Award granted to a "covered employee" does
not comply or is inconsistent with the requirements of Code Section 162(m) or
regulations thereunder, such provision shall be construed or deemed amended to
the extent necessary to conform to such requirements, and no provision shall be
deemed to confer upon the Committee or any other person discretion to increase
the amount of compensation otherwise payable to a "covered employee" in
connection with any such Award upon attainment of the performance objectives.

         (k)     Governing Law.  The validity, construction, and effect of the
Plan, any rules and regulations relating to the Plan, and any Award Agreement
shall be determined in accordance with the Delaware General Corporation Law, to
the extent applicable, other laws (including those governing contracts) of the
State of Texas, without giving effect to principles of conflicts of laws, and
applicable federal law.

         (1)     Effective Date; Plan Termination.  The Plan shall become
effective as of February 24, 1994; provided, however, that the Plan shall be
subject to approval by the affirmative votes of the holders of a majority of
voting securities present in person or represented by proxy, and entitled to
vote at the next annual meeting of Company stockholders for which the record
date is after the effective date of the Plan, or any adjournment thereof, or
prior to such annual meeting at a special meeting of stockholders or by the
written consent of the holders of a majority of voting securities entitled to
vote, in accordance with applicable provisions of the Delaware General
Corporation Law.  Any Awards granted under the Plan prior to such approval of
stockholders shall be effective when granted (unless, with respect to any
Award, the Committee specifies otherwise at the time of grant), but no such
Award may be exercised or settled, no restrictions relating to any Award may
lapse, no Stock (other than Restricted Stock) may be delivered prior to such
stockholder approval, and, if stockholders fail to approve the Plan as
specified hereunder, any previously granted Award shall be forfeited and
cancelled, and Participants shall repay to the Company any payments received
pursuant to Dividend Equivalents or dividend payments on Restricted Stock.  The
Plan shall terminate at such time, after 1999, that the Company has no further
obligations with respect to any Award granted under the Plan.

As approved by the Compensation Committee and the Board of Directors of the
Company on February 24, 1994.

                                                                    EXHIBIT 99.2


                                 SANIFILL, INC.
                       1989 STOCK OPTION PLAN, AS AMENDED

         1.      Purpose.  This 1989 Stock Option Plan, as amended (the
"Plan"), of Sanifill, Inc. (the "Company"), for directors, persons affiliated
with the Company and employees, is intended to advance the best interest of the
Company by providing such persons with additional incentive and by increasing
their proprietary interest in the success of the Company.

         2.      Administration.  The Plan shall be administered by a committee
to be appointed by the Board of Directors of the Company (the "Committee").
Members of the Committee shall not be eligible, and shall not have been
eligible at any time within one year prior to their appointment to the
Committee, to participate in the Plan, except as specifically authorized under
Section 4, or in any other stock option or similar plan of the Company or any
subsidiaries.  All questions of interpretation and application of the Plan
shall be subject to the determination, which shall be final and binding, of a
majority of the whole Committee, except for the granting of options (the
"Options") which shall be granted by unanimous vote or consent of the
Committee.  The Committee shall consist of not less than three members of the
Board of Directors, all of whom shall be directors of the Company who are not
officers or full-time employees of the Company or any of its subsidiaries.

         3.      Option Shares.  The stock subject to the Options and other
provisions of the Plan shall be shares of the Company's Common Stock, $.01 par
value (the "Common Stock").  Options granted under the Plan will not be
incentive stock options ("Incentive Stock Options") within the meaning of
Section 422A of the Internal Revenue Code of 1986, as amended (the "Code").
The total amount of the Common Stock with respect to which Options may be
granted shall be determined as of January 1 for each year that the Plan is in
effect and shall be equal to 12 percent of the outstanding shares of Common
Stock on such date, subject to adjustment in accordance with the provisions of
Paragraph 14 hereof, provided that, except for an adjustment in accordance with
the provisions of Paragraph 14, the number of shares available for issuance
under the Plan shall not be decreased as a result of a decrease in the number
of shares outstanding.  Such shares may be treasury shares or authorized but
unissued shares.  In the event that any outstanding Option (or portion thereof)
shall for any reason expire, be exercised or forfeited, the shares of Common
Stock allocable to such expired, forfeited or exercised Option (or portion
thereof) may again be subject to an Option under the Plan.

         4.      Eligibility.  The individuals who shall be eligible to
participate in the Plan shall be such directors, persons affiliated with the
Company and employees of the Company, or of any corporation in which the
company owns, directly or indirectly, stock possessing fifty percent (50%) or
more of the total combined voting power of all classes of stock, as the
Committee shall determine from time to time.





   2



         (a)     Grants to Employees and Affiliates.  All employees and
affiliates of the Company shall be eligible to participate in the Plan and
shall be granted Options as determined by unanimous vote or consent of the
Committee.

         (b)     Grants to Non-Employee Directors.  (i) Each Non-Employee
Director (meaning directors of the Company who are not officers or full-time
employees of the Company or any of its subsidiaries or who were not officers or
directors of, or otherwise affiliated with, any business acquired by or any
company merged or consolidated with or into the Company) shall on the June 1
coinciding with or immediately following the date on which he or she is
initially elected or appointed a director of the Company, be granted an option
to purchase 10,000 shares of Common Stock of the Company exercisable for the
full life of the Plan, subject to the six (6) month vesting period referred to
below and Sections 10 and 14 hereunder.  Thereafter, on June 1 of each
subsequent year in which the Non-Employee Director is still serving as a
director (whether or not the Non-Employee Director has continually remained a
director since the initial granting of the option to purchase 10,000 shares),
he or she shall automatically be granted an option to purchase an additional
5,000 shares of Common Stock of the Company exercisable for five years from the
date of grant, subject to the six (6) month vesting period referred to below
and Sections 10 and 14 hereunder.  The total amount of Common Stock with
respect to which Options may be granted under the Plan to Non-Employee
Directors of the Company as a group shall not exceed 225,000 shares in the
aggregate during any fiscal year; provided, that the class and the aforesaid
maximum number of shares shall be subject to adjustments in accordance with the
provisions of Paragraph 14 hereof.  All Options granted to Non-Employee
Directors, whether automatic or granted by the Executive Committee, shall not
be exercisable until six (6) months after the date of grant.

                 (ii)     In addition to the options provided for above in this
Section 4(b), each of the Company's Non- Employee Directors as of October 22,
1989 shall be granted an option to purchase 37,500 shares of the Company's
Common Stock at an exercise price of $1.67 per share.  Such option shall expire
on October 21, 1999, shall be exercisable immediately as to 15,000 shares and
as to an additional 7,500 shares on each succeeding October 22 following
October 22, 1989.

         5.      Option Price.  The price at which shares may be purchased
pursuant to Options granted under the Plan shall be no less than the fair
market value of the Common Stock.  For purposes of this Plan, the fair market
value of the Common Stock shall be the closing price thereof on the New York
Stock Exchange or such other exchange or trading market as shall be the
principal exchange or market for the trading of the Common Stock, or if there
is no such exchange or trading market, the fair market value as determined by
the Committee.

         6.      Duration of Options.  The Plan shall terminate on October 21,
1999.  The Committee, in its discretion, (i) shall determine the period over
which Options shall be exercisable, provided that no Options may be exercisable
subsequent to October 21, 1999, and (ii) may provide that an Option shall be
exercisable in various installments ("Vested Option Shares") through October
21, 1999 or any lesser period of time.





   3



         7.      Amount Exercisable.  The Vested Option Shares may be
exercised, so long as the Option is valid and outstanding, from time to time in
part or as a whole, and subject to such other conditions as the Committee in
its discretion may provide.

         8.      (a)      Exercise Of Options.

         Vested Option Shares shall be exercised by the delivery of written
notice to the Company setting forth the number of shares with respect to which
the Option is to be exercised, together with cash, certified check, bank draft
or postal or express money order payable to the order of the Company for an
amount equal to the option price of such shares and any income taxes required
to be withheld, and specifying the address to which the certificates for such
shares are to be mailed.

         As promptly as practicable after receipt of such written notification
and payment, the Company shall deliver to the option holder ("Optionee")
certificates for the number of shares with respect to which such Option has
been so exercised, issued in the Optionee's name; provided, that such delivery
shall be deemed effected for all purposes when a stock transfer agent of the
Company shall have deposited such certificates in the United States mail,
addressed to the Optionee, at the address specified pursuant to this Paragraph
8.

         (b)     Tax Election Available to Optionees who are Persons Described
in Section 16(a) of the Securities Exchange Act of 1934.

         Optionees who are persons described in Section 16(a) of the Exchange
Act ("Section 16(a) Optionees") at the time of exercise of an Option shall have
the option, rather than paying to the Company an amount required to be withheld
under applicable income tax laws in connection with the exercise of an Option,
to satisfy this obligation in whole or in part by making an election (the
"Election") to have the Company withhold shares of Common Stock having a fair
market value equal to the amount required to be withheld.  Such Election may
not be made within six months of the date the Option is granted (except in the
event of the Section 16(a) Optionee's death or disability) and must be made
concurrently with the Option exercise.  The Election shall be made by providing
the Company with written notice of such Election (attached to the written
notice of the Option exercise provided under Section 8(a) above).  The written
notice shall specify the date the amount of tax to be withheld is to be
determined (the "Tax Date") which shall be either (1) the same date that the
Option is exercised or (2) a date six months after the Option is exercised.  In
order for the Tax Date to be the same date that the Option is exercised, such
exercise must be made during the ten-day "window period" beginning on the third
day following the press release of the Company's quarterly or annual summary
statement of revenues and earnings and such written notice shall also indicate
the amount of the tax obligation, number of shares to be withheld together with
cash delivered (if any) to pay the withholding obligation.  For purposes of
calculating the withholding obligation when the Tax Date is the same as the
date of exercise, the fair market value of the shares to be utilized to
calculate the withholding obligation and to determine the number of shares to
be withheld to satisfy this obligation shall be based on the closing price of
the Common Stock as reported in The Wall Street Journal on the last trading day
preceding the date that the Option is exercised or, if not so





   4


reported, as determined by the Committee.  If the Tax Date chosen is six months
after the date the Option is exercised, the full number of shares will be
issued on exercise but the Section 16(a) Optionee will be unconditionally
obligated to tender back to the Company the proper number of shares and the
Company retains the right to place legends on the certificates representing
such shares or use other similar means to assure itself that the unconditional
obligation will be met, and the fair market value of the shares to be utilized
to calculate the withholding obligation shall be based on the closing price of
the Common Stock as reported in The Wall Street Journal on the day of, or, in
the event such day is not a trading day, the next trading day following, such
Tax Date or, if not so reported, as determined by the Committee.  The Election
shall be available to all Section 16(a) Optionees regardless of whether or not
he or she is subject to the withholding obligation.

         9.      Non-Transferability of Options.  Options shall not be
transferable and may not be sold, pledged or assigned in any manner otherwise
than by will or by the laws of descent and distribution.

         10.     Termination of Employment or Affiliation or Death of Optionee.
Except as may be otherwise expressly provided herein, Options shall terminate
on such date as shall be selected by the Committee in its discretion and
specified in the option agreement; however, with respect to an employee, Vested
Option Shares will in all cases expire in three (3) months following the
severance of the affiliation or employment relationship between the Company and
the Optionee for any reason, for or without cause (other than death), or in the
case of employees' retirement in good standing from the employ of the Company
for reasons of age or disability under the then established rules of the
Company.  If an Optionee is a director of the Company at the time an Option is
granted to him, and he ceases to be a director, the Option shall terminate
three (3) months following the date he ceases to be a director; provided that
the Committee may extend such date if such person becomes an employee of the
Company.  Whether authorized leave of absence, or absence on military or
government service, shall constitute severance of the employment relationship
between the Company and the Optionee, in the case of options granted to
employees, shall be determined by the Committee at the time thereof.  In the
event of the death of the holder of an Option while serving as a director or
while affiliated with or while in the employ of the Company as the case may be
and before the date of expiration of such Option, such Option shall terminate
one (1) year following the date of such death regardless of the date of
expiration of such Option.  After the death of the Optionee, his executors,
administrators or any person or persons to whom his Option may be transferred
by will or by the laws of descent and distribution, shall have the right, at
any time prior to one (1) year following the date of such death, to exercise
the Option, in whole (without regard to any limitations set forth in or imposed
pursuant to Paragraph 6 hereof) or in part.  For the purpose of determining the
employment relationship between the Company and the Optionee, employment by any
corporation of which the Company owns, directly or indirectly, stock possessing
fifty percent (50%) or more of the total combined voting power of all classes
of stock shall be considered employment by the Company.

         11.     Requirements of Law.  The Company shall not be required to
sell or issue any shares under any Option if the issuance of such shares shall
constitute a violation by the Optionee or the





   5


Company of any provisions of any law or regulation of any governmental
authority.  In addition, in connection with the Securities Act of 1933 (as now
in effect or hereafter amended), upon exercise of any Option, the Company shall
not be required to issue such shares unless the Committee has received evidence
satisfactory to it to the effect that the holder of such Option will not
transfer such shares except pursuant to a registration statement in effect
under such Act or unless an opinion of counsel to the Company has been received
by the Company to the effect that such registration is not required.  Any
determination in this connection by the Committee shall be final, binding and
conclusive.  The Company may, but shall in no event be obligated to, register
any securities covered hereby pursuant to the Securities Act of 1933 (as now in
effect or as hereafter amended).  The Company shall not be obligated to take
any other affirmative action in order to cause the exercise of any Option or
the issuance of shares pursuant thereto to comply with any law or regulation of
any governmental authority.

         12.     No Rights as Stockholder.  No Optionee shall have rights as a
stockholder with respect to shares covered by his Option until the date of
issuance of a stock certificate for such shares; no adjustment for dividends,
or otherwise, shall be made if the record date therefor is prior to the date of
issuance of such certificate.

         13.     Employment Obligations.  The granting of any Option shall not
impose upon the Company any obligation to employ or become affiliated with or
continue to employ or be affiliated with any Optionee; and the right of the
Company to terminate the employment of any employee or affiliation of any other
person shall not be diminished or affected by reason of the fact that an Option
has been granted to him.

         14.     Changes in the Company's Capital Structure.  The existence of
outstanding Options shall not affect in any way the right or power of the
Company or its stockholders to make or authorize any or all adjustments,
recapitalizations, reorganizations or other changes in the Company's capital
structure or its business, or any merger or consolidation of the Company, or
any issue of bonds, debentures, preferred or prior preference stock ahead of or
affecting the Common Stock or the rights thereof, or the dissolution or
liquidation of the Company, or any sale or transfer of all or any part of its
assets or business, or any other corporate act or proceeding, whether of a
similar character or otherwise.

         If, while there are outstanding Options, the Company shall effect a
subdivision or consolidation of shares or other increase or reduction of the
number of shares of the Common Stock outstanding without receiving compensation
therefor in money, services or property, then (a) in the event of an increase
in the number of such shares outstanding, the number of shares of Common Stock
then subject to Options hereunder shall be proportionately increased; and (b)
in the event of a decrease in the number of such shares outstanding the number
of shares then available for Option hereunder shall be proportionately
decreased.

         After a merger of one or more corporations into the Company, or after
a consolidation of the Company and one or more corporations in which the
Company shall be the surviving corporation,





   6


each holder of an outstanding Option shall, at no additional cost, be entitled
upon exercise of such Option to receive (subject to any required action by
stockholders) in lieu of the number of shares as to which such Option shall
then be so exercisable, the number and class of shares of stock or other
securities to which such holder would have been entitled pursuant to the terms
of the agreement of merger or consolidation if, immediately prior to such
merger or consolidation, such holder had been the holder of record of a number
of shares of Common Stock equal to the number of shares as to which such Option
shall be so exercised.

         If the Company is merged into or consolidated with another corporation
under circumstances where the Company is not the surviving corporation, or if
the Company sells or otherwise disposes of substantially all its assets to
another corporation while unexercised Options remain outstanding under the
Plan, (i) subject to the provisions of clause (iii) below, and so long as the
successor entity is willing to assume the obligation to deliver shares of such
stock or other securities, after the effective date of such merger,
consolidation or sale, as the case may be, each holder of an outstanding Option
shall be entitled, upon exercise of such Option, to receive, in lieu of shares
of Common Stock, shares of such stock or other securities as the holder of
shares of Common Stock received pursuant to the terms of the merger,
consolidation or sale, and if any option holder is subsequently terminated
without cause subsequent to the merger, consolidation or sale, then he or she
shall have the right, at any time prior to three (3) months following the date
of termination without cause to exercise the Option, in whole (without regard
to any limitation set forth in or imposed pursuant to Paragraph 6 hereof) or in
part; (ii) the Board of Directors may waive any limitations set forth in or
imposed pursuant to Paragraph 6 hereof so that all Options, from and after a
date prior to the effective date of such merger, consolidation or sale, as the
case may be, specified by the Board, shall be exercisable in full; or (iii) all
outstanding Options may be canceled by the Board of Directors as of the
effective date of any such merger, consolidation or sale provided that (x)
notice of any such cancellation shall be given to each holder of an Option and
(y) each holder of an Option shall have the right to exercise such Option in
full (without regard to any limitations set forth in or imposed pursuant to
Paragraph 6 hereof) during a 30-day period preceding the effective date of such
merger, consolidation, sale or acquisition.

         No adjustment provided for in this Section 14 shall be made if such
adjustment would result in a modification of any Incentive Stock Option or
cause such Incentive Stock Option to fail to qualify as an incentive stock
option under the Code.

         Except as hereinbefore expressly provided, the issue by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, for cash or property, or for labor or services either upon direct
sale or upon the exercise of rights or warrants to subscribe therefor, or upon
conversion of shares or obligations of the Company convertible into such shares
or other securities, shall not affect, and no adjustment by reason thereof
shall be made with respect to, the number or price of shares of Common Stock
then subject to outstanding Options.

         15.     Amendment or Termination of Plan.  The Board of Directors may
modify, revise or terminate this Plan at any time and from time to time;
provided, however, that no such modification,





   7


revision or termination shall change or impair any Option previously granted
without the consent of the Optionee and provided further that the Board of
Directors of the Company may only make amendments in accordance with procedures
required under Rule 16b-3 and any such amendments must keep the Plan in
compliance with Rule 16b-3 or any successor thereto under the Exchange Act.

         16.     Written Agreement.  Each Option granted hereunder shall be
embodied in a written Option agreement which shall be subject to the terms and
conditions prescribed above, and shall be signed by the Optionee and by the
Chairman, the President or any Vice President of the Company for and in the
name and on behalf of the Company.  Such an option agreement shall contain such
other provisions as the Committee in its discretion shall deem advisable.

         17.     Effective Date of Plan.  The Plan shall become effective and
shall be deemed to have been adopted upon approval by the full Board of
Directors, subject to ratification by the stockholders of the Company.  Any
options granted under the Plan heretofore shall for all purposes hereof be
deemed to be granted hereunder.

                        Duration and Exercise of Warrant

         Section 2.01:    Duration of Warrant.  If this Warrant is not
exercised on or prior to the Expiration Time, it shall become void, and all
rights hereunder shall thereupon cease.

         Section 2.02:    Exercise of Warrant.  (a) The Warrantholder may
exercise this Warrant, in whole or in part, by presentation and surrender of
this Warrant to the Company at its principal executive offices with the
Subscription Form annexed hereto duly executed and accompanied by payment of
the full Exercise Price for each Warrant Share to be purchased on such
exercise.

                 (b)      Upon receipt of this Warrant with the Subscription
Form duly executed and accompanied by payment of the aggregate Exercise Price
for the Warrant Shares for which this Warrant is then being exercised, the
Company shall cause to be issued certificates for the total number of whole
shares of Common Stock for which this Warrant is being exercised in such
denominations as are requested by the Warrantholder, and the Company shall
thereupon deliver such certificates to the Warrantholder.  If at the time this
Warrant is exercised, a Registration Statement with respect to the Warrant
Shares is not in effect under the Securities Act, the Company may require the
Warrantholder to make such representations, and may place such legends on
certificates representing the Warrant Shares, as may be reasonably required in
the opinion of counsel to the Company to permit the Warrant Shares to be issued
without such registration.

                 (c)      In case the Warrantholder shall exercise this Warrant
with respect to less than all of the Warrant Shares that may be purchased under
this Warrant, the Company shall execute a new warrant in the form of this
Warrant for the balance of such Warrant Shares and deliver such new warrant to
the Warrantholder.

                 (d)      The Company shall pay any and all stock transfer and
similar taxes which may be payable in respect of the issue of this Warrant or
in respect of the issue of any Warrant Shares.

         Section 2.03:    Reservation of Shares.  The Company hereby agrees
that at all times there shall be reserved for issuance and delivery upon
exercise of this Warrant such number of shares of Common Stock as may from time
to time be issuable upon exercise of this Warrant.  All such shares shall be
duly authorized, and when issued upon such exercise, shall be validly issued,
fully paid and nonassessable, free and clear of all liens, security interests,
charges and other encumbrances.

         Section 2.04:    Fractional Shares.  The Company shall not be required
to issue any fraction of a share of its Common Stock in connection with the
exercise of this Warrant, and in any case

where the Warrantholder would, except for the provisions of this Section 2.04,
be entitled under the terms of this Warrant to receive a fraction of a share
upon the exercise of this Warrant, the Company shall, upon the exercise of this
Warrant and receipt of the Exercise Price (as adjusted to cover the fraction of
the share), issue the number of whole shares purchasable upon exercise of this
Warrant.  The Company shall not be required to make any cash or other
adjustment in respect of such fraction of a share to which the Warrantholder
would otherwise be entitled.

         Section 2.05:    Listing.  Prior to the issuance of any shares of
Common Stock upon exercise of this Warrant, the Company shall secure the
listing of such shares of Common Stock upon each national securities exchange
or automated quotation system, if any, upon which shares of Common Stock are
then listed (subject to official notice of issuance upon exercise of this
Warrant) and shall maintain, so long as any other shares of Common Stock shall
be so listed, such listing of all shares of Common Stock from time to time
issuable upon the exercise of this Warrant; and the Company shall so list on
each national securities exchange or automated quotation system, and shall
maintain such listing of, any other shares of capital stock of the Company
issuable upon the exercise of this Warrant if and so long as any shares of the
same class shall be listed on such national securities exchange or automated
quotation system.


                                  ARTICLE III

                            Adjustment of Shares of
                            Common Stock Purchasable

         The number and kind of Warrant Shares shall be subject to adjustment
from time to time upon the happening of certain events as provided in this
Article III.  The existence of this Warrant shall not affect in any way the
right or power of the Company or its stockholders to make or authorize any or
all adjustments, recapitalizations, reorganizations or other changes in the
Company's capital structure or its business, or any merger or consolidation of
the Company, or any issue of bonds, debentures, preferred or prior preference
stock, or the dissolution or liquidation of the Company, or any sale or
transfer of all or any part of its assets or business, or any other corporate
act or proceeding, whether of a similar character or otherwise.

         Section 3.01:    Certain Adjustments.  If the Company shall effect a
subdivision or consolidation of shares or other increase or reduction of the
number of shares of the Common Stock outstanding without receiving a
compensation therefor in money, services or property, then (a) in the event of
an increase in the number of such shares outstanding, the number of shares of
Common Stock then subject to purchase hereunder shall be proportionately
increased; and (b) in the event of a decrease in the number of such shares
outstanding the number of shares of Common Stock then subject to purchase
hereunder shall be proportionately decreased.

         After a merger of one or more corporations into the Company, or after
a consolidation of the Company and one or more corporations in which the
Company shall be the surviving corporation,

the Warrantholder shall, at no additional cost, be entitled upon exercise of
this Warrant to receive (subject to any required action by stockholders) in
lieu of the number of shares purchasable upon exercise of this Warrant, the
number and class of shares of stock or other securities to which such holder
would have been entitled pursuant to the terms of the agreement of merger or
consolidation if, immediately prior to such merger or consolidation, the
Warrantholder had been the holder of record of a number of shares of Common
Stock equal to the number of shares as to which this Warrant shall be so
exercised.

         If the Company is merged into or consolidated into another corporation
under circumstances where the Company is not the surviving corporation, or if
the Company sells or otherwise disposes of substantially all of its assets to
another corporation while all or any portion of this Warrant remains
unexercised, the Warrantholder shall be entitled, upon exercise of this
Warrant, to receive, in lieu of shares of Common Stock, shares or such other
securities as the holder of shares of Common Stock received pursuant to the
terms of such merger, consolidation or sale.

         Section 3.02:    Notice of Adjustment.  Whenever the number of Warrant
Shares is adjusted as herein provided, the Company shall prepare and deliver
forthwith to the Warrantholder a certificate signed by its Chairman, President,
any Vice President, Treasurer or Secretary, setting forth the number of shares
purchasable upon the exercise of this Warrant after such adjustment, setting
forth a brief statement of the facts requiring such adjustment and setting
forth the computation by which adjustment was made.

         Section 3.03:    No Other Adjustment.  Except as hereinbefore
expressly provided, the issue by the Company of shares of stock of any class or
securities convertible into shares of stock of any class, for cash or property,
or for labor or services either upon direct sale or upon the exercise of rights
or warrants to subscribe therefor, or upon conversion of shares of obligations
of the Company convertible into such shares of other securities, shall not
affect, and no adjustment by reason thereof shall be made with respect to, the
number of shares of Common Stock then subject to purchase under this Warrant.

                                   ARTICLE IV

                           Other Provisions Relating
                           to Rights of Warrantholder

         Section 4.01:    No Rights as Shareholders; Notice to Warrantholder.
Nothing contained in this Warrant shall be construed as conferring upon the
Warrantholder the right to vote or to receive dividends or to consent or to
receive notice as a shareholder in respect of any meeting of shareholders for
the election of directors of the Company or of any other matter, or any rights
whatsoever as a shareholder of the Company.  The Company shall, however, give
notice to the Warrantholder by registered mail if at any time prior to the
Expiration Time or exercise in full of this Warrant, any of the following
events shall occur:





   6



                 (a)      the Company shall authorize the payment of any
dividend payable in any securities upon shares of Common Stock or authorize the
making of any distribution (other than a cash dividend) to all holders of
Common Stock;

                 (b)      the Company shall authorize the issuance to all
holders of Common Stock of any additional shares of Common Stock (or securities
that are convertible into or exercisable for shares of Common Stock) or of
rights, options or warrants to subscribe for or purchase Common Stock (or
securities that are convertible into or exercisable for shares of Common Stock)
or of any other subscription rights, options or warrants;

                 (c)      a dissolution, liquidation or winding up of the 
Company; or

                 (d)      a capital reorganization or reclassification of the
Common Stock (other than a subdivision or combination of the outstanding Common
Stock and other than a change in the par value of the Common Stock) or any
consolidation or merger of the Company with or into another corporation (other
than a consolidation or merger in which the Company is the continuing
corporation and that does not result in any reclassification or change of
Common Stock outstanding) or in the case of any sale or conveyance to another
corporation of the property of the Company as an entirety or substantially as
an entirety.

Such giving of notice shall be initiated (i) at least 5 Business Days prior to
the date fixed as a record date or effective date or the date of closing of the
Company's stock transfer books for the determination of the shareholders
entitled to such dividend, distribution or subscription rights, or for the
determination of the shareholders entitled to vote on such proposed merger,
consolidation, sale, conveyance, dissolution, liquidation or winding up.  Such
notice shall specify such record date or the date of closing the stock transfer
books, as the case may be.  Failure to provide such notice shall not affect the
validity of any action taken in connection with such dividend, distribution or
subscription rights, or proposed merger, consolidation, sale, conveyance,
dissolution, liquidation or winding up.

         Section 4.02:    Lost, Stolen, Mutilated or Destroyed Warrants.  If
this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such
terms as to indemnity or otherwise as it may in its discretion impose (which
shall, in the case of a mutilated Warrant, include the surrender thereof),
issue a new Warrant of like denomination and tenor as, and in substitution for
this Warrant.


                                   ARTICLE V

                              Transfer of Warrant

         Section 5.01:    Restrictions on Transfer.  This Warrant may not be
disposed of or encumbered (any such action, a "Transfer") other than by will or
the laws of descent and distribution.

construed in accordance with the laws of the State of Texas.

         Section 6.03     Severability.  In the event that any one or more of
the provisions contained herein, or the application thereof in any
circumstances, is held invalid, illegal or unenforceable, the validity,
legality and enforceability of any such provisions in every other respect and
of the remaining provisions contained herein shall not be affected or impaired
thereby.

         Section 6.04     Notice.  Any notices or certificates by the Company

any other address, to such other address, and if to the Company, addressed to

Company under its corporate seal as of the 6th day of October, 1992.
