anniversaries of the Commencement Date, subject (except as otherwise provided
herein) to Executive's continuous employment with the Company through the
applicable vesting date (the 'Restricted Stock Grant'). The Restricted Stock
Grant shall be deemed outstanding shares for all purposes and Executive shall be
fully vested in any cash dividends paid therein (and non-cash dividends being
subject to the same forfeiture provisions as the underlying Restricted Stock
Grant shares).

5.       TERMINATION OF EMPLOYMENT.

Executive's employment hereunder may be terminated under the following
circumstances:


(a)      DEATH. Executive's employment hereunder shall terminate upon
         Executive's death.


(b)      TOTAL DISABILITY. The Company may terminate Executive's employment
         hereunder upon Executive becoming 'Totally Disabled'. For purposes of
         this Agreement, Executive shall be 'Totally Disabled' if Executive has
         been physically or mentally incapacitated so as to render Executive
         incapable of performing Executive's material usual and customary duties
         under this Agreement for six (6) consecutive months (such consecutive
         absence not being deemed interrupted by Executive's return to service
         for less than 10 consecutive business days if absent thereafter for the
         same illness or disability). Any such termination shall be upon thirty
         (30) days written notice given at any time thereafter while Executive
         remains Totally Disabled, provided that a termination for Total
         Disability hereunder shall not be effective if Executive returns to
         full performance of his duties within such thirty (30) day period.

(c)      TERMINATION BY THE COMPANY FOR CAUSE. The Company may terminate
         Executive's employment hereunder for 'Cause' at any time within ninety
         (90) days after the Chairman of the Audit or Governance Committee of
         the Board has knowledge thereof.

         (i)   For purposes of this Agreement, the term 'Cause' shall be limited
               to (1) willful misconduct by Executive with regard to the Company
               which has a material adverse effect on the Company; (2) the
               willful refusal of Executive to attempt to follow the proper
               written direction of the Board, provided that the foregoing
               refusal shall not be 'Cause' if Executive in good faith believes
               that such direction is illegal, unethical or immoral and promptly
               so notifies the Board; (3) substantial and continuing willful
               refusal by the Executive to attempt to perform the duties
               required of him hereunder (other than any such failure resulting
               from incapacity due to physical or mental illness) after a
               written demand for substantial performance is delivered to the
               Executive by the Board which specifically identifies the manner
               in which it is believed that the Executive has substantially and
               continually refused to attempt to perform his duties hereunder;
               or (4) the Executive being convicted of a felony (other than a
               felony involving a traffic violation or as a result of vicarious
               liability). For purposes of this paragraph, no act, or failure to
               act, on Executive's part shall be considered 'willful' unless
               done 







                                  Page 4 of 19


               or omitted to be done, by him not in good faith and without
               reasonable belief that his action or omission was in the best
               interests of the Company.

         (ii)  A Notice of Termination for Cause shall mean a notice that shall
               indicate the specific termination provision in Section 5(c)(i)
               relied upon and shall set forth in reasonable detail the facts
               and circumstances which provide for a basis for termination for
               Cause. Further, a Notification for Cause shall be required to
               include a copy of a resolution duly adopted by at least
               two-thirds (2/3rds) of the entire membership of the Board at a
               meeting of the Board which was called for the purpose of
               considering such termination and which Executive and his
               representative had the right to attend and address the Board,
               finding that, in the good faith of the Board, Executive engaged
               in conduct set forth in the definition of Cause herein and
               specifying the particulars thereof in reasonable detail. The date
               of termination for a termination for Cause shall be the date
               indicated in the Notice of Termination. Any purported termination
               for Cause which is held by a court or arbitrator not to have been
               based on the grounds set forth in this Agreement or not to have
               followed the procedures set forth in this Agreement shall be
               deemed a termination by the Company without Cause.

(d)      VOLUNTARY TERMINATION BY EXECUTIVE. Executive may terminate employment
         hereunder with or without Good Reason at any time upon written notice
         to the Company.

         (i)   A Termination for Good Reason means a termination by Executive by
               written notice given within ninety (90) days after the occurrence
               of the Good Reason event, unless such circumstances are fully
               corrected prior to the date of termination specified in the
               Notice of Termination for Good Reason. For purposes of this
               Agreement, 'Good Reason' shall mean the occurrence or failure to
               cause the occurrence, as the case may be, without Executive's
               express written consent, of any of the following circumstances:
               (1) any material diminution of Executive's positions, duties or
               responsibilities hereunder (except in each case in connection
               with the termination of Executive's employment for Cause or Total
               Disability or as a result of Executive's death, or temporarily as
               a result of Executive's illness or other absence), the cessation
               of Executive to report to the Chief Executive Officer of the
               Company or the assignment to Executive of duties or
               responsibilities that are inconsistent with Executive's then
               position; provided that if the Company becomes a fifty percent or
               more subsidiary of any other entity, Executive shall be deemed to
               have a material diminution of his position unless he is also
               Senior Vice President and Chief Financial Officer reporting to
               the Chief Executive Officer of the ultimate parent entity; (2)
               removal of, or the non-re-election of, the Executive from officer
               positions with the Company specified herein or removal of the
               Executive from any of his then officer positions; (3) requiring
               Executive's principal place of business to be located other than
               in the Houston, Texas greater Metropolitan region; (4) a failure
               by the Company (I) to continue any bonus plan, program or
               arrangement in which Executive is entitled to participate (the
               'Bonus Plans'), provided that any such Bonus Plans may be
               modified at the Company's discretion from time to time but shall
               be deemed terminated if (x) any such plan does not remain
               substantially in 





                                  Page 5 of 19


               the form in effect prior to such modification and (y) if plans
               providing Executive with substantially similar benefits are not
               substituted therefor ('Substitute Plans'), or (II) to continue
               Executive as a participant in the Bonus Plans and Substitute
               Plans on at least the same basis as to potential amount of the
               bonus as Executive participated in prior to any change in such
               plans or awards, in accordance with the Bonus Plans and the
               Substitute Plans; (5) any material breach by the Company of any
               provision of this Agreement, including without limitation Section
               10 hereof; or (6) failure of any successor to the Company
               (whether direct or indirect and whether by merger, acquisition,
               consolidation or otherwise) to assume in a writing delivered to
               Executive upon the assignee becoming such, the obligations of the
               Company hereunder.

         (ii)  A Notice of Termination for Good Reason shall mean a notice that
               shall indicate the specific termination provision relied upon and
               shall set forth in reasonable detail the facts and circumstances
               claimed to provide a basis for Termination for Good Reason. The
               failure by Executive to set forth in the Notice of Termination
               for Good Reason any facts or circumstances which contribute to
               the showing of Good Reason shall not waive any right of Executive
               hereunder or preclude Executive from asserting such fact or
               circumstance in enforcing his rights hereunder. The Notice of
               Termination for Good Reason shall provide for a date of
               termination not less than ten (10) nor more than sixty (60) days
               after the date such Notice of Termination for Good Reason is
               given, provided that in the case of the events set forth in
               Sections (i)(1) or (2) the date may be five (5) days after the
               giving of such notice.

(e)      TERMINATION BY THE COMPANY WITHOUT CAUSE. The Company may terminate
         Executive's employment hereunder without Cause at any time upon written
         notice to Executive.

(f)      EFFECT OF TERMINATION. Upon any termination of employment, Executive
         shall immediately resign from all Board memberships and other positions
         with the Company or any of its subsidiaries held by him at such time.

shall be entitled to the following compensation and benefits upon such
termination:

         shall pay the following amounts to Executive's beneficiary or estate:

               date of death, any accrued but unpaid expenses required to be
               reimbursed under this Agreement, any vacation accrued to the date
               of termination, any earned but unpaid bonuses for any prior
               period, a pro-rata 'bonus' or incentive compensation payment to
               the 





                                  Page 6 of 19


               extent payments are awarded senior executives and paid at the
               same time as senior executives are paid, and any vacation accrued
               to the date of death.

         (ii)  Any benefits to which Executive may be entitled pursuant to the
               plans, policies and arrangements (including those referred to in
               Sections 4(f)-(h) hereof), as determined and paid in accordance
               with the terms of such plans, policies and arrangements.

         (iii) An amount equal to the Base Salary (at the rate in effect as of

               Executive if Executive had continued in employment for two
               additional years. Said payments will be paid to Executive's
               estate or beneficiary at the same time and in the same manner as
               such compensation would have been paid if Executive had remained
               in active employment.

         (iv)  As of the date of termination by reason of Executive's death,
               stock options awarded to Executive shall be fully vested and
               Executive's estate or beneficiary shall have up to one (1) year
               from the date of death to exercise all such options.

         (v)   As otherwise specifically provided herein.

(b)      TERMINATION BY REASON OF TOTAL DISABILITY. In the event that

               date of termination, any accrued but unpaid expenses required to
               be reimbursed under this Agreement, any vacation accrued to the
               date of termination and any earned but unpaid bonuses for any
               prior period. Executive shall also be eligible for a pro-rata
               bonus or incentive compensation payment to the extent such awards
               are made to senior executives for the year in which Executive is
               terminated.

         (ii)  Any benefits to which Executive may be entitled pursuant to the
               plans, policies and arrangements (including those referred to in
               Sections 4(f)-(h) hereof) shall be determined and paid in
               accordance with the terms of such plans, policies and
               arrangements.

         (iii) An amount equal to the Base Salary (at the rate in effect as of
               the date of Executive's Total Disability) which would have been
               payable to Executive if Executive had continued in active
               employment for two years following termination of employment,
               less any payments under any long-term disability plan or
               arrangement paid for by the Company. Payment shall be made at the
               same time and in the same manner as such compensation would have
               been paid if Executive had remained in active employment until
               the end of such period.

         (iv)  As of the date of termination by reason of Executive's Total
               Disability, Executive shall be fully vested in all stock option
               awards and Executive shall have up to one 





                                  Page 7 of 19


               (1) year from the date of termination by reason of Total 
               Disability to exercise all such options.

         (v)   As otherwise specifically provided herein.

(c)      TERMINATION FOR CAUSE. In the event that Executive's employment is
         terminated by the Company for Cause, the Company shall pay the
         following amounts to Executive:

         (i)   Any accrued but unpaid Base Salary for services rendered to the
               date of termination, any accrued but unpaid expenses required to
               be reimbursed under this Agreement, any vacation accrued to the
               date of termination and any earned but unpaid bonuses for any
               prior period.

         (ii)  Any benefits to which Executive may be entitled pursuant to the
               plans, policies and arrangements (including those referred to in
               Sections 4(f)-(h) hereof) shall be determined and paid in
               accordance with the terms of such plans, policies and
               arrangements.

         (iii) As otherwise specifically provided herein.

         Any options, restricted stock or other awards that have not vested
         prior to the date of such termination of employment shall be cancelled
         and any options held by Executive shall be cancelled, whether or not
         then vested.

(d)      VOLUNTARY TERMINATION BY EXECUTIVE. In the event that Executive
         voluntarily terminates employment other than for Good Reason, the
         Company shall pay the following amounts to Executive:

         (i)   Any accrued but unpaid Base Salary for services rendered to the
               date of termination, any accrued but unpaid expenses required to
               be reimbursed under this Agreement, any vacation accrued to the
               date of termination and any earned but unpaid bonuses for any
               prior period.

         (ii)  Any benefits to which Executive may be entitled pursuant to the
               plans, policies and arrangements (including those referred to in
               Sections 4(f)-(h) hereof) shall be determined and paid in
               accordance with the terms of such plans, policies and
               arrangements.

         (iii) As otherwise specifically provided herein.

         Any options, restricted stock or other awards that have not vested
         prior to the date of such termination of employment shall be cancelled
         and Executive shall have 90 days following termination of employment to
         exercise any previously vested options (or, if earlier, until the
         stated expiration thereof).



                                  Page 8 of 19

(e)      TERMINATION BY THE COMPANY WITHOUT CAUSE; TERMINATION BY EXECUTIVE FOR
         GOOD REASON. In the event that Executive's employment is terminated by
         the Company for reasons other than death, Total Disability or Cause, or
         Executive terminates his employment for Good Reason, the Company shall
         pay the following amounts to Executive:

         (i)   Any accrued but unpaid Base Salary for services rendered to the
               date of termination, any accrued but unpaid expenses required to
               be reimbursed under this Agreement, any vacation accrued to the
               date of termination and any earned but unpaid bonuses for any
               prior period.

         (ii)  Any benefits to which Executive may be entitled pursuant to the
               plans, policies and arrangements referred to in Sections 4(f)-(h)
               hereof shall be determined and paid in accordance with the terms
               of such plans, policies and arrangements.

         (iii) An amount equal to two times the sum of Executive's Base Salary
               plus his Target Annual Bonus (in each case as then in effect), of
               which one-half shall be paid in a lump sum within ten (10) days
               after such termination and one-half shall be paid during the two
               (2) year period beginning on the date of Executive's termination
               and shall be paid at the same time and in the same manner as Base
               Salary would have been paid if Executive had remained in active
               employment until the end of such period.

         (iv)  The Company at its expense will continue for Executive and
               Executive's spouse and dependents, all health benefit plans,
               programs or arrangements, whether group or individual, and also
               including deferred compensation, disability, automobile, and
               other benefit plans, in which Executive was entitled to
               participate at any time during the twelve-month period prior to
               the date of termination, until the earliest to occur of (A) two
               years after the date of termination; (B) Executive's death
               (provided that benefits payable to Executive's beneficiaries
               shall not terminate upon Executive's death); or (C) with respect
               to any particular plan, program or arrangement, the date
               Executive becomes covered by a comparable benefit by a subsequent
               employer. In the event that Executive's continued participation
               in any such plan, program, or arrangement of the Company is
               prohibited, the Company will arrange to provide Executive with
               benefits substantially similar to those which Executive would
               have been entitled to receive under such plan, program, or
               arrangement, for such period on a basis which provides Executive
               with no additional after tax cost.

         (v)   Except to the extent prohibited by law, and except as otherwise
               provided herein, Executive will be 100% vested in all benefits,
               awards, and grants accrued but unpaid as of the date of
               termination under any pension plan, profit sharing plan,
               supplemental and/or incentive compensation plans in which
               Executive was a participant as of the date of termination.
               Executive shall also be eligible for a bonus or incentive
               compensation payment, at the same time, on the same basis, and to
               the same extent payments are made to senior executives, pro-rated
               for the fiscal year in which the Executive is terminated.



                                  Page 9 of 19

         (vi)  As of the date of such termination of employment, the stock
               options awarded to Executive pursuant to Section 4(e)(i) hereof
               and the Restricted Stock Grant shall be fully vested. Executive
               shall continue to vest in all other stock option awards or
               restricted stock awards over the two (2) year period commencing
               on the date of such termination. Executive shall have two (2)
               years and six (6) months after the date of termination to
               exercise all vested options, unless by virtue of the particular
               stock option award, the option grant expires on an earlier date.

         (vii) As otherwise specifically provided herein.

(f)      NO OTHER BENEFITS OR COMPENSATION. Except as may be provided under this
         Agreement, under the terms of any incentive compensation, employee
         benefit, or fringe benefit plan applicable to Executive at the time of
         Executive's termination or resignation of employment, Executive shall
         have no right to receive any other compensation, or to participate in
         any other plan, arrangement or benefit, with respect to future periods
         after such termination or resignation.

(g)      NO MITIGATION; NO SET-OFF. In the event of any termination of
         employment hereunder, Executive shall be under no obligation to seek
         other employment and there shall be no offset against any amounts due
         Executive under this Agreement on account of any remuneration
         attributable to any subsequent employment that Executive may obtain.
         The amounts payable hereunder shall not be subject to setoff,
         counterclaim, recoupment, defense or other right which the Company may
         have against the Executive or others, except upon obtaining by the
         Company of a final unappealable judgment against Executive.

7.   RESIGNATION BY EXECUTIVE FOR GOOD REASON AND COMPENSATION PAYABLE FOLLOWING
     CHANGE IN CONTROL.

(a)      RESIGNATION FOR GOOD REASON FOLLOWING CHANGE IN CONTROL. In the event a
         'Change in Control' occurs and Executive terminates his employment for
         Good Reason thereafter, or the Company terminates Executive's
         employment other than for Cause or such termination for Good Reason or
         without Cause occurs in contemplation of such Change in Control (any
         termination within six (6) months prior to such Change in Control being
         presumed to be in contemplation unless rebutted by clear and
         demonstrable evidence to the contrary), the Company shall pay the
         following amounts to Executive:

         (i)   The payments and benefits provided for in Section 6(e), except
               that (A) the entire amount calculated pursuant to Section
               6(e)(iii) shall be paid in a lump-sum and (B) the benefit
               continuation period in Section 6(e)(iv) shall be three years.

         (ii)  Executive will be 100% vested in all benefits, awards, and grants
               (including stock option grants and stock awards, all of such
               stock options exercisable for three (3) years following
               Termination) accrued but unpaid as of the date of termination
               under any non-qualified pension plan, supplemental and/or
               incentive compensation or bonus plans, in which Executive was a
               participant as of the date 








                                 Page 10 of 19

               of termination. Executive shall also receive a bonus or incentive
               compensation payment (the 'bonus payment'), payable at 100% of
               the maximum bonus available to Executive, pro-rated as of the
               effective date of the termination. The bonus payment shall be
               payable within five (5) days after the effective date of
               Employee's termination. Except as may be provided under this
               Section 7 or under the terms of any incentive compensation,
               employee benefit, or fringe benefit plan applicable to Executive
               at the time of Executive's resignation from employment, Executive
               shall have no right to receive any other compensation, or to
               participate in any other plan, arrangement or benefit, with
               respect to future periods after such resignation or termination.

(b)      CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.

         (i)   In the event that the Executive shall become entitled to payments
               and/or benefits provided by this Agreement or any other amounts
               in the 'nature of compensation' (whether pursuant to the terms of
               this Agreement or any other plan, arrangement or agreement with
               the Company, any person whose actions result in a change of
               ownership or effective control covered by Section 280G(b)(2) of
               the Code or any person affiliated with the Company or such
               person) as a result of such change in ownership or effective
               control (collectively the 'Company Payments'), and such Company
               Payments will be subject to the tax (the 'Excise Tax') imposed by
               Section 4999 of the Code (and any similar tax that may hereafter
               be imposed by any taxing authority) the Company shall pay to the
               Executive at the time specified in subsection (iv) below an
               additional amount (the 'Gross-up Payment') such that the net
               amount retained by the Executive, after deduction of any Excise
               Tax on the Company Payments and any U.S. federal, state, and for
               local income or payroll tax upon the Gross-up Payment provided
               for by this Section 7(b), but before deduction for any U.S.
               federal, state, and local income or payroll tax on the Company
               Payments, shall be equal to the Company Payments.

         (ii)  For purposes of determining whether any of the Company Payments
               and Gross-up Payments (collectively the 'Total Payments') will be
               subject to the Excise Tax and the amount of such Excise Tax, (x)
               the Total Payments shall be treated as 'parachute payments'
               within the meaning of Section 280G(b)(2) of the Code, and all
               'parachute payments' in excess of the 'base amount' (as defined
               under Code Section 280G[b][3] of the Code) shall be treated as
               subject to the Excise Tax, unless and except to the extent that,
               in the opinion of the Company's independent certified public
               accountants appointed prior to any change in ownership (as
               defined under Code Section 280G[b][2]) or tax counsel selected by
               such accountants (the 'Accountants') such Total Payments (in
               whole or in part) either do not constitute 'parachute payments,'
               represent reasonable compensation for services actually rendered
               within the meaning of Section 280G(b)(4) of the Code in excess of
               the 'base amount' or are otherwise not subject to the Excise Tax,
               and (y) the value of any non-cash benefits or any deferred
               payment or benefit shall be determined by the Accountants in
               accordance with the principles of Section 280G of the Code.



                                 Page 11 of 19

         (iii) For purposes of determining the amount of the Gross-up Payment,
               the Executive shall be deemed to pay U.S. federal income taxes at
               the highest marginal rate of U.S. federal income taxation in the
               calendar year in which the Gross-up Payment is to be made and
               state and local income taxes at the highest marginal rate of
               taxation in the state and locality of the Executive's residence
               for the calendar year in which the Company Payment is to be made,
               net of the maximum reduction in U.S. federal income taxes which
               could be obtained from deduction of such state and local taxes if
               paid in such year. In the event that the Excise Tax is
               subsequently determined by the Accountants to be less than the
               amount taken into account hereunder at the time the Gross-up
               Payment is made, the Executive shall repay to the Company, at the
               time that the amount of such reduction in Excise Tax is finally
               determined, the portion of the prior Gross-up Payment
               attributable to such reduction (plus the portion of the Gross-up
               Payment attributable to the Excise Tax and U.S. federal, state
               and local income tax imposed on the portion of the Gross-up
               Payment being repaid by the Executive if such repayment results
               in a reduction in Excise Tax or a U.S. federal, state and local
               income tax deduction), plus interest on the amount of such
               repayment at the rate provided in Section 1274(b)(2)(B) of the
               Code. Notwithstanding the foregoing, in the event any portion of
               the Gross-up Payment to be refunded to the Company has been paid
               to any U.S. federal, state and local tax authority, repayment
               thereof (and related amounts) shall not be required until actual
               refund or credit of such portion has been made to the Executive,
               and interest payable to the Company shall not exceed the interest
               received or credited to the Executive by such tax authority for
               the period it held such portion. The Executive and the Company
               shall mutually agree upon the course of action to be pursued (and
               the method of allocating the expense thereof) if the Executive's
               claim for refund or credit is denied.

               In the event that the Excise Tax is later determined by the
               Accountant or the Internal Revenue Service to exceed the amount
               taken into account hereunder at the time the Gross-up Payment is
               made (including by reason of any payment the existence or amount
               of which cannot be determined at the time of the Gross-up
               Payment), the Company shall make an additional Gross-up Payment
               in respect of such excess (plus any interest or penalties payable
               with respect to such excess) at the time that the amount of such
               excess is finally determined.

         (iv)  The Gross-up Payment or portion thereof provided for in
               subsection (iii) above shall be paid not later than the thirtieth
               (30th) day following an event occurring which subjects the
               Executive to the Excise Tax; provided, however, that if the
               amount of such Gross-up Payment or portion thereof cannot be
               finally determined on or before such day, the Company shall pay
               to the Executive on such day an estimate, as determined in good
               faith by the Accountant, of the minimum amount of such payments
               and shall pay the remainder of such payments (together with
               interest at the rate provided in Section 1274(b)(2)(B) of the
               Code), subject to further payments pursuant to subsection (iii)
               hereof, as soon as the amount thereof can reasonably be
               determined, but in no event later than the ninetieth day after
               the occurrence of the event subjecting the Executive to the
               Excise Tax. In the event that the amount of the estimated
               payments exceeds the amount subsequently 




                                 Page 12 of 19


               determined to have been due, such excess shall constitute a loan
               by the Company to the Executive, payable on the fifth day after
               demand by the Company (together with interest at the rate
               provided in Section 1274(b)(2)(B) of the Code).

         (v)   In the event of any controversy with the Internal Revenue Service
               (or other taxing authority) with regard to the Excise Tax, the
               Executive shall permit the Company to control issues related to
               the Excise Tax (at its expense), provided that such issues do not
               potentially materially adversely affect the Executive, but the
               Executive shall control any other issues. In the event the issues
               are interrelated, the Executive and the Company shall in good
               faith cooperate so as not to jeopardize resolution of either
               issue, but if the parties cannot agree the Executive shall make
               the final determination with regard to the issues. In the event
               of any conference with any taxing authority as to the Excise Tax
               or associated income taxes, the Executive shall permit the
               representative of the Company to accompany the Executive, and the
               Executive and the Executive's representative shall cooperate with
               the Company and its representative.

         (vi)  The Company shall be responsible for all charges of the
               Accountant.

         (vii) The Company and the Executive shall promptly deliver to each
               other copies of any written communications, and summaries of any
               verbal communications, with any taxing authority regarding the
               Excise Tax covered by this Section 7(b).

(c)      CHANGE IN CONTROL. For purposes of this Agreement, 'Change in Control'
         means the occurrence of any of the following events:

         (i)   any Person is or becomes the Beneficial Owner, directly or
               indirectly, of securities of the Company (not including in the
               securities beneficially owned by such person any securities
               acquired directly from the Company or its Affiliates)
               representing twenty-five percent (25%) or more of the combined
               voting power of the Company's then outstanding voting securities;

         (ii)  the following individuals cease for any reason to constitute a
               majority of the number of directors then serving: individuals
               who, on the Commencement Date, constitute the Board and any new
               director (other than a director whose initial assumption of
               office is in connection with an actual or threatened election
               contest, including but not limited to a consent solicitation,
               relating to the election of directors of the Company) whose
               appointment or election by the Board or nomination for election
               by the Company's stockholders was approved or recommended by a
               vote of the at least two-thirds (2/3rds) of the directors then
               still in office who either were directors on the Commencement
               Date or whose appointment, election or nomination for election
               was previously so approved or recommended;

         (iii) there is a consummated merger or consolidation of the Company or
               any direct or indirect subsidiary of the Company with any other
               corporation, other than (A) a merger or consolidation which would
               result in the voting securities of the 







                                 Page 13 of 19


               Company outstanding immediately prior thereto continuing to
               represent (either by remaining outstanding or by being converted
               into voting securities of the surviving or parent entity) more
               than fifty percent (50%) of the combined voting power of the
               voting securities of the Company or such surviving or parent
               equity outstanding immediately after such merger or consolidation
               or (B) a merger or consolidation effected to implement a
               recapitalization of the Company (or similar transaction) in which
               no Person, directly or indirectly, acquired twenty-five percent
               (25%) or more of the combined voting power of the Company's then
               outstanding securities (not including in the securities
               beneficially owned by such person any securities acquired
               directly from the Company or its Affiliates); or

         (iv)  the stock holders of the Company approve a plan of complete
               liquidation of the Company or there is consummated an agreement
               for the sale or disposition by the Company of all or
               substantially all of the Company's assets (or any transaction
               having a similar effect), other than a sale or disposition by the
               Company of all or substantially all of the Company's assets to an
               entity, at least fifty percent (50%) of the combined voting power
               of the voting securities of which are owned by stockholders of
               the Company in substantially the same proportions as their
               ownership of the Company immediately prior to such sale.

         For purposes of this Section 7(c), the following terms shall have the
following meanings:

               (i) 'Affiliate' shall mean an affiliate of the Company, as
               defined in Rule 12b-2 promulgated under Section 12 of the
               Securities Exchange Act of 1934, as amended from time to time
               (the 'Exchange Act');

               (ii) 'Beneficial Owner' shall have the meaning set forth in Rule
               13d-3 under the Exchange Act;

               (iii) 'Person' shall have the meaning set forth in Section
               3(a)(9) of the Exchange Act, as modified and used in Sections
               13(d) and 14(d) thereof, except that such term shall not include
               (1) the Company, (2) a trustee or other fiduciary holding
               securities under an employee benefit plan of the Company, (3) an
               underwriter temporarily holding securities pursuant to an
               offering of such securities or (4) a corporation owned, directly
               or indirectly, by the stockholders of the Company in
               substantially the same proportions as their ownership of shares
               of Common Stock of the Company.

8.       RESTRICTIVE COVENANTS.

(a)      COMPETITIVE ACTIVITY. Executive covenants and agrees that at all times
         during Executive's period of employment with the Company, and for two
         (2) years thereafter, Executive will not engage in, assist, or have any
         active interest or involvement, whether as an employee, agent,
         consultant, creditor, advisor, officer, director, stockholder
         (excluding holding of less than 3% of the stock of a public company),
         partner, proprietor or any type of principal whatsoever in any person,
         firm, or business entity which, directly or indirectly, is materially
         engaged in the waste management business competitive with 





                                 Page 14 of 19


         that conducted and carried on by the Company, without the Company's
         specific written consent to do so. 'Material' shall mean more than five
         (5%) percent of their revenue is generated from the waste management
         business; provided that the revenues within Executive's area of
         responsibility or authority are more than 10% composed of revenues from
         the waste disposal business. Notwithstanding the foregoing, Executive
         may be employed by or provide services to, an investment banking firm,
         law firm or consulting firm that provides services to entities
         described in the previous sentence, provided that Executive does not
         personally represent or provide services to such entities.

(b)      NON-SOLICITATION. Executive covenants and agrees that at all times
         during Executive's period of employment with the Company, and for a
         period of two (2) years after the Termination thereof, whether such
         termination is voluntary or involuntary by wrongful discharge, or
         otherwise, Executive will not directly and personally knowingly (i)
         induce any customers of the Company or corporations affiliated with the
         Company to patronize any similar business which competes with any
         material business of the Company; (ii) after his termination of
         employment, request or advise any customers of the Company or
         corporations affiliated with the Company to withdraw, curtail or cancel
         such customer's business with the Company; or (iii) after his
         termination of employment, individually or through any person, firm,
         association or corporation with which he is now, or may hereafter
         become associated, solicit, entice or induce any then employee of the
         Company, or any subsidiary of the Company, to leave the employ of the
         Company, or such other corporation, to accept employment with, or
         compensation from the Executive, or any person, firm, association or
         corporation with which Executive is affiliated without prior written
         consent of the Company. The foregoing shall not prevent Executive from
         serving as a reference for employees.

(c)      PROTECTED INFORMATION. Executive recognizes and acknowledges that
         Executive has had and will continue to have access to various
         confidential or proprietary information concerning the Company and
         corporations affiliated with the Company of a special and unique value
         which may include, without limitation, (i) books and records relating
         to operation, finance, accounting, sales, personnel and management,
         (ii) policies and matters relating particularly to operations such as
         customer service requirements, costs of providing service and
         equipment, operating costs and pricing matters, and (iii) various trade
         or business secrets, including customer lists, route sheets, business
         opportunities, marketing or business diversification plans, business
         development and bidding techniques, methods and processes, financial
         data and the like, to the extent not generally known in the industry
         (collectively, the 'Protected Information'). Executive therefore
         covenants and agrees that Executive will not at any time, either while
         employed by the Company or afterwards, knowingly make any independent
         use of, or knowingly disclose to any other person or organization
         (except as authorized by the Company) any of the Protected Information,
         provided that (i) while employed by the Company, Executive may in good
         faith make disclosures he believes desirable, and (ii) Executive may
         comply with legal process.




                                 Page 15 of 19

9.       ENFORCEMENT OF COVENANTS.

(a)      RIGHT TO INJUNCTION. Executive acknowledges that a breach of the
         covenants set forth in Section 8 hereof will cause irreparable damage
         to the Company with respect to which the Company's remedy at law for
         damages may be inadequate. Therefore, in the event of breach or
         threatened breach of the covenants set forth in this section by
         Executive, Executive and the Company agree that the Company shall be
         entitled to the following particular forms of relief, in addition to
         remedies otherwise available to it at law or equity; injunctions, both
         preliminary and permanent, enjoining or restraining such breach or
         threatened breach and Executive hereby consents to the issuance thereof
         forthwith and without bond by any court of competent jurisdiction.

(b)      SEPARABILITY OF COVENANTS. The covenants contained in Section 8 hereof
         constitute a series of separate covenants, one for each applicable
         State in the United States and the District of Columbia, and one for
         each applicable foreign country. If in any judicial proceeding, a court
         shall hold that any of the covenants set forth in Section 8 exceed the
         time, geographic, or occupational limitations permitted by applicable
         laws, Executive and the Company agree that such provisions shall and
         are hereby reformed to the maximum time, geographic, or occupational
         limitations permitted by such laws. Further, in the event a court shall
         hold unenforceable any of the separate covenants deemed included
         herein, then such unenforceable covenant or covenants shall be deemed
         eliminated from the provisions of this Agreement for the purpose of
         such proceeding to the extent necessary to permit the remaining
         separate covenants to be enforced in such proceeding.

         Executive and the Company further agree that the covenants in Section 8
         shall each be construed as a separate agreement independent of any
         other provisions of this Agreement, and the existence of any claim or
         cause of action by Executive against the Company whether predicated on
         this Agreement or otherwise, shall not constitute a defense to the
         enforcement by the Company of any of the covenants of Section 8.

10.      INDEMNIFICATION.

The Company shall indemnify and hold harmless Executive to the fullest extent
permitted by law for any action or inaction of Executive while serving as an
officer and director of the Company or, at the Company's request, as an officer
or director of any other entity or as a fiduciary of any benefit plan. The
Company shall cover the Executive under directors and officers liability
insurance both during and, while potential liability exists, after the
Employment Term in the same amount and to the same extent as the Company covers
its other officers and directors.

11.      DISPUTES AND PAYMENT OF ATTORNEY'S FEES.

If at any time during the term of this Agreement or afterwards there should
arise any dispute as to the validity, interpretation or application of any term
or condition of this Agreement, the Company agrees, upon written demand by
Executive (and Executive shall be entitled upon application to any court of
competent jurisdiction, to the entry of a mandatory injunction, without the
necessity of posting any bond with respect thereto, compelling the Company) to
promptly provide sums sufficient to pay on a current basis (either directly or
by reimbursing Executive) 






                                 Page 16 of 19


Executive's costs and reasonable attorney's fees (including expenses of
investigation and disbursements for the fees and expenses of experts, etc.)
incurred by Executive in connection with any such dispute or any litigation,
provided that Executive shall repay any such amounts paid or advanced if
Executive is not the prevailing party with respect to at least one material
claim or issue in such dispute or litigation. The provisions of this Section 11,
without implication as to any other section hereof, shall survive the expiration
or termination of this Agreement and of Executive's employment hereunder.

12.      WITHHOLDING OF TAXES.

The Company may withhold from any compensation and benefits payable under this
Agreement all applicable federal, state, local, or other taxes.

13.      SOURCE OF PAYMENTS.

All payments provided under this Agreement, other than payments made pursuant to
a plan which provides otherwise, shall be paid from the general funds of the
Company, and no special or separate fund shall be established, and no other
segregation of assets made, to assure payment. Executive shall have no right,
title or interest whatever in or to any investments which the Company may make
to aid the Company in meeting its obligations hereunder. To the extent that any
person acquires a right to receive payments from the Company hereunder, such
right shall be no greater than the right of an unsecured creditor of the
Company.

14.      ASSIGNMENT.

Except as otherwise provided in this Agreement, this Agreement shall inure to
the benefit of and be binding upon the parties hereto and their respective
heirs, representatives, successors and assigns. This Agreement shall not be
assignable by Executive (but any payments due hereunder which would be payable
at a time after Executive's death shall be paid to Executive's designated
beneficiary or, if none, his estate) and shall be assignable by the Company only
to any financially solvent corporation or other entity resulting from the
reorganization, merger or consolidation of the Company with any other
corporation or entity or any corporation or entity to or with which the
Company's business or substantially all of its business or assets may be sold,
exchanged or transferred, and it must be so assigned by the Company to, and
accepted as binding upon it by, such other corporation or entity in connection
with any such reorganization, merger, consolidation, sale, exchange or transfer
in a writing delivered to Executive in a form reasonably acceptable to Executive
(the provisions of this sentence also being applicable to any successive such
transaction).

15.      ENTIRE AGREEMENT; AMENDMENT.

This Agreement shall supersede any and all existing oral or written agreements,
representations, or warranties between Executive and the Company or any of its
subsidiaries or affiliated entities relating to the terms of Executive's
employment by the Company. It may not be amended except by a written agreement
signed by both parties.




                                 Page 17 of 19

16.      GOVERNING LAW.

This Agreement shall be governed by and construed in accordance with the laws of
the State of Texas applicable to agreements made and to be performed in that
State, without regard to its conflict of laws provisions.

17.      REQUIREMENT OF TIMELY PAYMENTS.

If any amounts which are required, or determined to be paid or payable, or
reimbursed or reimbursable, to Executive under this Agreement (or any other
plan, agreement, policy or arrangement with the Company) are not so paid
promptly at the times provided herein or therein, such amounts shall accrue
interest, compounded daily, at an 8% annual percentage rate, from the date such
amounts were required or determined to have been paid or payable, reimbursed or
reimbursable to Executive, until such amounts and any interest accrued thereon
are finally and fully paid, provided, however, that in no event shall the amount
of interest contracted for, charged or received hereunder, exceed the maximum
non-usurious amount of interest allowed by applicable law.

18.      NOTICES.

Any notice, consent, request or other communication made or given in connection
with this Agreement shall be in writing and shall be deemed to have been duly
given when delivered or mailed by registered or certified mail, return receipt
requested, or by facsimile or by hand delivery, to those listed below at their
following respective addresses or at such other address as each may specify by

19.      MISCELLANEOUS.

(a)      WAIVER. The failure of a party to insist upon strict adherence to any
         term of this Agreement on any occasion shall not be considered a waiver
         thereof or deprive that party of the right thereafter to insist upon
         strict adherence to that term or any other term of this Agreement.

(b)      SEPARABILITY. Subject to Section 9 hereof, if any term or provision of
         this Agreement is declared illegal or unenforceable by any court of
         competent jurisdiction and cannot be modified to be enforceable, such
         term or provision shall immediately become null and void, leaving the
         remainder of this Agreement in full force and effect.

(c)      HEADINGS. Section headings are used herein for convenience of reference
         only and shall not affect the meaning of any provision of this
         Agreement.




                                 Page 18 of 19

(d)      RULES OF CONSTRUCTION. Whenever the context so requires, the use of the
         singular shall be deemed to include the plural and vice versa.

(e)      COUNTERPARTS. This Agreement may be executed in any number of
         counterparts, each of which so executed shall be deemed to be an
         original, and such counterparts will together constitute but one
         Agreement.

IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as of
the day and year first above written.
