                  any of the following: (a) conviction of a crime (including
                  conviction on a nolo contendere plea) involving a felony or,

                  sickness, illness or injury); (c) fraud or embezzlement
                  determined in accordance with the Company's normal, internal

                  an act constituting Cause at any time prior to a payment date
                  for an award, regardless of whether the individual terminates
                  employment voluntarily or is terminated involuntarily, and
                  regardless of whether the individual's termination initially
                  was considered to have been for Cause.

         (iii)    Any determination of Cause under this Agreement shall be made
                  by the Company after giving Employee a reasonable opportunity
                  to be heard.

(d)      TERMINATION BY THE COMPANY WITHOUT CAUSE. In the event that Employee's
         employment is terminated by the Company pursuant to Section 5(e) for
         reasons other than death, Total Disability or Cause, the Company shall
         pay the following amounts to Employee:

                  be made at the same time and in the same manner as such
                  compensation would have been paid if Employee had remained in
                  active employment until the end of such period. The Employee
                  shall also be eligible for a bonus or incentive compensation

                  (a) last day of period during which Employee receives payment
                  in accordance with clause (iii) above; (b) Employee's death
                  (provided that benefits payable to Employee's beneficiaries
                  shall not terminate upon Employee's death); or (c) with
                  respect to any particular plan, program or arrangement, the

         "Change in Control" occurs, Executive will be paid the compensation
         described in this Section 7 if Executive resigns or is terminated (both
         a "resignation" and "termination" being referred to as "termination"
         for the purposes of this Section 7) from employment with the Company at
         any time prior to the six (6) month anniversary of the date of the
         Change in Control following the occurrence of any of the following
         events:

         (i)      the removal of Executive as President of Canadian Waste
                  Services, Inc., except in connection with the termination of
                  Executive's employment as a result of death, or by the Company
                  for Disability or Cause, or by Executive other than for the
                  reasons described in this Section 7(a);

         (ii)     a reduction by the Company in Executive's Base Salary as in
                  effect immediately before a Change in Control plus all
                  increases therein subsequent thereto;

         (iii)    the failure of the Company substantially to maintain and to
                  continue Executive's participation in the Company's benefit
                  plans as in effect immediately before a Change in Control and
                  with all improvements therein subsequent thereto (other than
                  those plans or improvements that have expired thereafter in
                  accordance with their original terms), or the taking of any
                  action which would materially reduce Executive's benefits
                  under any of such plans or deprive Executive of any material
                  fringe benefit enjoyed by Executive immediately before a

                  required by law;

   6


                  such as a lump sum relocation bonus, salary adjustment and/or
                  housing allowance so that Executive can purchase comparable
                  primary housing if required to relocate (it being the
                  intention of this Section 7[a][iv] to keep the Executive
                  "whole" if required to relocate). In this regard, comparable
                  housing shall be determined by comparing factors such as
                  location (taking into account, by way of example, items such
                  as the value of the surrounding neighborhood, reputation of
                  the public school district, if applicable, security and
                  proximity to Executive's place of work), quality of
                  construction, design, age, size of the housing and the ratio
                  of the monthly payments including principle, interest, taxes
                  and insurance to the Executive's take home pay, to housing
                  most recently owned by Executive prior to, or as of the
                  effective date of the change of control;

         (v)      the failure by the Company to pay Executive any portion of
                  Executive's current compensation, or any portion of
                  Executive's compensation deferred under any plan, agreement or
                  arrangement of or with the Company, within seven (7) days of
                  the date such compensation is due; or

         (vi)     the failure by the Company to obtain an assumption of, and
                  agreement to perform the obligations of the Company under this
                  Agreement by any successor to the Company.

(b)      COMPENSATION PAYABLE. In the event that Executive terminates employment
         pursuant to Section 7(a), 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.

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

         (iii)    The payments and benefits provided for in Section 6(d) except
                  that the period with respect to which severance is calculated
                  pursuant to Section 6 (d) (iii) will be three years and the
                  benefit continuation period in Section (d) (iv) will be three
                  years.

         (iv)     Executive will be 100% vested in all benefits, awards, and
                  grants (including stock options) 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 of
                  termination. Executive shall also be eligible for a bonus or
                  incentive compensation payment (the "bonus payment"), payable
                  at 100% of the maximum bonus available to Executive. The bonus
                  payment shall be payable within five (5) days after the
                  effective date of Employee's termination. Employee shall have
                  until the expiration date shown on the stock option award in
                  which to exercise the options which have vested pursuant to
                  this section.

         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.

(c)      CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY. In the event that any
         portion of the benefits payable under this Agreement, and any other
         payments and benefits under any other agreement with, or plan of the
         Company to or for the benefit of the Executive (in aggregate, "Total
         Payments") constitute an "excess parachute payment" within the meaning
         of Section 280G of the Internal Revenue Code (the "Code"), then the
         Company shall pay the Executive as promptly as practicable following
         such determination an additional amount (the "Gross-up Payment")
         calculated as described below to reimburse the Executive on an
         after-tax basis for any excise tax imposed on such payments under
         Section 4999 of the Code. The Gross-up Payment shall equal the amount,
         if any, needed to ensure that the net parachute payments


                                  Page 6 of 11
   7


         (including the Gross-up Payment) actually received by the Executive
         after the imposition of federal and state income, employment and excise
         taxes (including any interest or penalties imposed by the Internal
         Revenue Service), are equal to the amount that the Executive would have
         netted after the imposition of federal and state income and employment
         taxes, had the Total Payments not been subject to the taxes imposed by
         Section 4999. For purposes of this calculation, it shall be assumed
         that the Executive's tax rate will be the maximum federal rate to be
         computed with regard to Section 1(g) of the Code.

         In the event that the Executive and the Company are unable to agree as
         to the amount of the Gross-up Payment, if any, the Company shall select
         a law firm or accounting firm from among those regularly consulted
         (during the twelve-month period immediately prior to a
         Change-in-Control) by the Company regarding federal income tax matters
         and such law firm or accounting firm shall determine the amount of
         Gross-up Payment and such determination shall be final and binding upon
         the Executive and the Company.

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

         (i)      Any transfer to, assignment to, or any acquisition by any
                  person, corporation or other entity, or group thereof, of the
                  beneficial ownership, within the meaning of Section 13(d) of
                  the Securities Exchange Act of 1934, of any securities of the
                  Company, which transfer, assignment or acquisition results in
                  such person, corporation, entity, or group thereof, becoming
                  the beneficial owner, directly or indirectly, of securities of
                  the Company representing 25 percent (25%) or more of the
                  combined voting power of the Company's then outstanding
                  securities; or

         (ii)     As a result of a tender offer, merger, consolidation, sale of
                  assets, or contested election, or any combination of such
                  transactions, the persons who were directors immediately
                  before the transaction shall cease to constitute a majority of
                  the Board of Directors of the Company or any successor to the
                  Company.

8. RESTRICTIVE COVENANTS

(a)      COMPETITIVE ACTIVITY. Employee covenants and agrees that at all times
         during Employee's period of employment with the Company, and while
         Employee is receiving payments pursuant to Section 6 of this Agreement,
         Employee will not, directly or indirectly, 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 1% 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 engaged in
         the same business as that conducted and carried on by the Company,
         without the Company's specific written consent to do so. Furthermore,
         in consideration of the specialized training and access to confidential
         information, for a period of one (1) year after the date of termination
         of Employee's employment, or one (1) year following the cessation of
         payments made pursuant to Section 6 of this Agreement, whether such
         termination is voluntary or involuntary, by wrongful discharge, or
         otherwise, whichever date is later, Employee will not directly or
         indirectly, engage in a competitive activity in any of the geographic
         markets in which the Employee has worked for the twelve (12) months
         preceding his termination, or within 75 miles of the principal place of
         business of the Company, the principal place of business of any
         corporation or other entity owned, controlled by (or otherwise
         affiliated with) the Company by which Employee may also be employed or
         served by Employee, or any other geographic location in which Employee
         has specifically represented the interests of the Company or such other
         affiliated entity, during the twelve (12) months prior to the
         termination of Employee's employment, 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 1% of the stock of a public company),
         partner, proprietor or any type of principal whatsoever in any person,
         firm, or business entity


                                  Page 7 of 11
   8


         which, directly or indirectly, is engaged in the same business as that
         conducted and carried on by the Company, without the Company's specific
         written consent to do so.

(b)      NON-SOLICITATION. Employee covenants and agrees that at all times
         during Employee's period of employment with the Company, and for a
         period of one (1) year after the date of termination of Employee's
         employment, or the date of the cessation of payments made to the
         Employee pursuant to Section 6 of this Agreement, whichever is later,
         whether such termination is voluntary or involuntary by wrongful
         discharge, or otherwise, Employee will not directly or indirectly (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) canvass, solicit or accept any
         similar business from any customer of the Company or corporations
         affiliated with the Company; (iii) directly or indirectly 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; (iv) directly or indirectly disclose to any other person,
         firm or corporation the names or addresses of any of the customers of
         the Company or corporations affiliated with the Company; or (v)
         individually of through any person, firm, association or corporation
         with which Employee is now or may hereafter become associated, cause,
         solicit, entice, or induce any present or future employee of the
         Company, or any corporation affiliated with the Company to leave the
         employ of the Company, or such other corporation to accept employment
         with, or compensation from, the Employee or any such person, firm,
         association or corporation without the prior written consent of the
         Company.

(c)      NON-DISPARAGEMENT. Employee covenants and agrees that Employee shall
         not engage in any pattern of conduct that involves the making or
         publishing of written or oral statements or remarks (including, without
         limitation, the repetition or distribution of derogatory rumors,
         allegations, negative reports or comments) which are disparaging,
         deleterious or damaging to the integrity, reputation or good will of
         the Company, its management, or of management of corporations
         affiliated with the Company.

(d)      PROTECTED INFORMATION. Employee recognizes and acknowledges that
         Employee 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 business opportunities, marketing or
         business diversification plans, business development and bidding
         techniques, methods and processes, financial data and the like
         (collectively, the "Protected Information"). Employee therefore
         covenants and agrees that Employee 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.

9. ENFORCEMENT OF COVENANTS.

(a)      TERMINATION OF EMPLOYMENT AND FORFEITURE OF COMPENSATION. Employee
         agrees that any breach by Employee of any of the covenants set forth in
         Section 7 hereof during Employee's employment by the Company, shall be
         grounds for immediate dismissal of Employee and forfeiture of any
         accrued and unpaid salary, bonus, commissions or other compensation of
         such Employee as liquidated damages, which shall be in addition to and
         not exclusive of any and all other rights and remedies the Company may
         have against Employee.

(b)      RIGHT TO INJUNCTION. Employee acknowledges that a breach of the
         covenants set forth in Section 7 hereof will cause irreparable damage
         to the Company with respect to which the Company's remedy at law for
         damages will be inadequate. Therefore, in the event of breach of
         anticipatory breach of the covenants set


                                  Page 8 of 11
   9


         forth in this section by Employee, Employee 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; (i) injunctions, both preliminary and permanent, enjoining or
         retraining such breach or anticipatory breach and Employee hereby
         consents to the issuance thereof forthwith and without bond by any
         court of competent jurisdiction; and (ii) recovery of all reasonable
         sums expended and costs, including reasonable attorney's fees, incurred
         by the Company to enforce the covenants set forth in this section.

(c)      SEPARABILITY OF COVENANTS. The covenants contained in Section 7 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 7 exceed the
         time, geographic, or occupational limitations permitted by applicable
         laws, Employee 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. Employee and the
         Company further agree that the covenants in Section 7 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
         Employee 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 7.

10. WITHHOLDING OF TAXES.

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


                                  Page 9 of 11

11. NON-DISCLOSURE OF AGREEMENT TERMS.

Employee agrees that Employee will not disclose the terms of this Agreement to
any third party other than Employee's immediate family, attorney, accountants,
or other consultants or advisors or except as may be required by any
governmental authority.

12. 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. Employee 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.

13. 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 Employee.

14. ENTIRE AGREEMENT; AMENDMENT.

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

15. 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.

16. 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

17. 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 8 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.

(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.
