                                                                  EXECUTION COPY

                              EMPLOYMENT AGREEMENT

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into
effective as of December 1, 2001 (the "Effective Date"), by and between IESI
Corporation, a Delaware corporation ("IESI" or "Employer"), and Thomas J. Cowee
("Executive").

                                   WITNESSETH

     WHEREAS, Employer desires to employ Executive, and Executive desires to be
employed by Employer, upon the terms and subject to the conditions set forth in
this Agreement;

     NOW, THEREFORE, in consideration of the mutual promises and covenants
herein set forth and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, Employer and Executive, intending
to be legally bound, agree as follows:

1.   EMPLOYMENT - IESI hereby employs Executive as its Senior Vice President and
     Chief Financial Officer upon the terms and conditions and for the
     compensation herein provided. Executive hereby agrees to be so employed and
     to render the services specified herein for Employer and any subsidiaries
     or affiliates of Employer. In his capacity as its Senior Vice President and
     Chief Financial Officer of Employer, Executive shall devote his full and
     undivided business time and attention to his duties and responsibilities.

2.   TERM OF EMPLOYMENT - Subject to the provisions for termination as provided
     in Section 5 hereof, the term of Executive's employment hereunder (the
     "Term") shall be for a period commencing as of the Effective Date and
     terminating December 31, 2003. Beginning December 31, 2002 and continuing
     each December 31st thereafter, the term of this Agreement shall extend one
     additional year unless the Company advises the Employee, in writing, to the
     contrary. This annual extension provision shall not be effective unless the
     Employee advises (during the first week of December of each year) the
     Chairman of the Board of Directors of the Company, in writing, of the
     upcoming extension date.

3.   DUTIES AND POWERS - During the Term, Executive agrees as follows: to devote
     his full and exclusive business time and attention to the business of
     Employer and of any subsidiaries or affiliates of the Company including,
     but not limited to, IESI Corporation (excluding reasonable vacations and
     sick leave in accordance with Employer's policies consistent with his
     position); to perform all duties in a professional and prudent manner, to
     devote the best of his skill, energy, experience and judgment to such
     duties; and to communicate to Employer suggestions, ideas or information
     that may be helpful to Employer in its businesses. Executive shall have all
     the powers and agrees to perform all of the duties associated with his
     position as Senior Vice President and Chief Financial Officer, subject to
     all lawful policies and guidelines as may be established by the Board of
     Directors of Employer (the "Board"). Executive agrees not to engage in any
     other activity or own any interest that would conflict with the interests
     of Employer or would interfere with his responsibilities to Employer and
     the performance of his duties hereunder; PROVIDED, HOWEVER, that: (i)
     passive investment of less than 5% of the outstanding securities of any
     company or any other investment that does not conflict with

<Page>

     Executive's performance of his duties to Employer hereunder shall be deemed
     not to violate this provision, it being understood that, except as set
     forth below, an investment of more than 5% in a company other than Employer
     engaged in the solid waste industry shall be deemed to conflict with
     Executive's performance of his duties hereunder; and (ii) Executive may
     engage in activities involving charitable, educational, religious and
     similar types of organizations, speaking engagements and similar type
     activities to the extent that such other activities do not detract from the
     performance by Executive of his duties and obligations hereunder.

4.   COMPENSATION AND BENEFITS - For all services rendered by Executive pursuant
     to this Agreement, Employer shall compensate Executive as follows:

     (a)  BASE COMPENSATION - In consideration of the full and faithful
     performance by Executive of his obligations hereunder during the Term and
     subject to the terms and conditions set forth herewith, Employer (or any
     subsidiary or affiliate of Employer for which Executive also provides
     services hereunder) shall pay to Executive $200,000 per annum (such annual
     compensation as it may be increased from time to time shall be referred to
     herein as the "Base Compensation"). Executive's Base Compensation will be
     paid in accordance with Employer's customary payroll practices (but not
     less frequently than monthly) and will be prorated based upon the number of
     days elapsed in any partial year. Base Compensation shall be reviewed
     annually and may be increased at the sole discretion of the Board.

     (b)  BONUS - In addition to the Base Compensation payable to Executive,
     Executive may be awarded performance bonuses from time to time, in the sole
     discretion of the Board.

     (c)  BENEFITS - Vacation. During the Term, Executive shall be entitled to
     such benefits (including health, dental and disability coverage, life
     insurance, 401K, holiday and sick days) as Employer may, from time to time,
     make available to its executive employees. Executive shall be entitled to
     three (3) weeks paid vacation during each calendar year of employment, with
     such vacation allowance being prorated in respect of any employment period
     of less than 12 full months. Notwithstanding the foregoing, Executive shall
     not be entitled to take more than two weeks of vacation leave at any one
     time. Unused vacation shall not be carried forward.

     (d)  EXPENSES - Executive shall be entitled to reimbursement for his
     ordinary and necessary business expenses, including country club dues not
     to exceed $2,500 annually, incurred in the performance of his duties under
     this Agreement if supported by reasonable documentation as required by
     Employer in accordance with its usual practices.

     (e)  CAR ALLOWANCE - During the Term, Executive shall be entitled to a car
     allowance of $750 per month. Executive shall be responsible for all costs
     associated with such car (other than fuel expenses reimbursable under
     Section 4(d) hereof).

                                       -2-

     (f)  LIABILITY FOR TAXES - Employer shall have no liability for any tax
     obligation of Executive attributable to any payment made under this
     Agreement except for customary federal and state withholding taxes (e.g.,
     social security, Medicare, etc.). Employer may withhold from any such
     payment such amounts as may be required by applicable provisions of the
     Internal Revenue Code, other tax laws, and the rules and regulations of the
     Internal Revenue Service and other tax agencies, as in effect at the time
     of any such payment.

5.   EXPIRATION/TERMINATION OF EMPLOYMENT

     (a)  EXPIRATION AT END OF TERM - Unless earlier terminated in accordance
     with the terms of this Agreement, Executive's employment shall expire at
     the end of the Term.

     (b)  TERMINATION AT WILL - The parties acknowledge and agree that
     Executive's employment hereunder is an employment at will. Notwithstanding
     any other provision contained in this Agreement, either Executive or
     Employer may terminate Executive's employment hereunder at any time with or
     without Cause (as defined in subsection 5(e)(i)) or for Good Reason (as
     defined in subsection 5(e)(ii)) at his election upon prior written notice
     (a "Termination Notice") to the other. A Termination Notice shall be
     effective upon delivery to the other party and the termination shall be
     effective as of the date set forth in such Termination Notice (hereinafter,
     the "Termination Date").

     (c)  EFFECT OF EXPIRATION OR TERMINATION FOR CAUSE OR WITHOUT GOOD REASON -
     Upon the expiration of this Agreement pursuant to subsection 5(a) hereof or
     upon a termination of this Agreement pursuant to subsection 5(b) hereof by
     Employer with Cause or by Executive without Good Reason, Executive shall be
     entitled to payment of: (i) Base Compensation through the Termination Date;
     (ii) amounts accrued under benefit plans in which Executive is a
     participant as of the Termination Date.

     (d)  EFFECT OF TERMINATION WITHOUT CAUSE OR FOR GOOD REASON - Upon the
     termination of this Agreement pursuant to subsection 5(b) hereof by
     Employer without Cause or by Executive for Good Reason, Executive shall be
     entitled to payment of: (i) Base Compensation (at the rate in effect on the
     date of such termination) and all benefits under Section 4(c) hereof for
     the remainder of the Term; and (ii) amounts accrued under benefit plans in
     which Executive is a participant as of such termination date.

     (e)  EFFECT OF TERMINATION FOLLOWING A CHANGE OF CONTROL - Notwithstanding
     any other provision in this Agreement to the contrary, following a Change
     in Control as defined in Section 6 hereof, (a) if Executive chooses to
     terminate his employment without Good Reason pursuant to Section 5(b)
     hereof, such termination shall be treated as termination under Section 5(c)
     hereof; (b) if Employer (or its successor) terminates Executive's
     employment without Cause pursuant to Section 5(b) hereof, such termination
     shall be treated as a termination under Section 5(d) hereof, except that
     Executive shall receive Base Compensation and benefits for the "Payout
     Period" (as defined below). For the purposes of this Agreement, "Payout
     Period" shall mean the greater of eighteen (18) months or the remainder of
     the Term. If a Change in Control as defined in Section 6

                                       -3-
<Page>

     occurs within 6 months after Executive has been terminated Without Cause or
     For Good Reason, then termination shall be treated as a termination
     following a Change of Control, and Executive shall receive Base
     Compensation and benefits as defined by the "Payout Period".

     (f)  DEFINITIONS OF "CAUSE" AND "GOOD REASON" - For purposes of this
     Agreement, the terms "Cause" and "Good Reason" shall have the following
     meanings:

          (i)  "Cause" shall mean (1) the failure of Executive to perform his
          duties with Employer (other than any such failure resulting from death
          or the inability of Executive to perform the essential functions of
          his job due, with or without a reasonable accommodation) or the
          material breach of this Agreement by Executive if Employer gives
          notice of such cause and it remains uncured for ten (10) days
          following such notice; (2) any act by Executive of fraud or dishonesty
          with respect to any aspect of Employer's business; (3) drug or alcohol
          abuse or related behavior that impedes Executive's job performance or
          brings Executive or Employer into disrepute in the community; (4)
          misappropriation of funds or any corporate opportunity: (5) a
          conviction or affirmative finding by an appropriate administrative
          agency that Executive is guilty of a felony or crime of moral
          turpitude (or a plea of nolo contendere thereto); (6) acts by
          Executive attempting to secure or securing any personal profit not
          fully disclosed to and approved by the Board in connection with any
          transaction entered into on behalf of Employer; or (7) gross, willful
          or wanton negligence or misconduct by Executive.

          (ii) "Good Reason" shall mean (1) a material and adverse change in
          Executive's status or position as an officer of Employer or a material
          reduction in the duties and responsibilities previously exercised by
          Executive, or any removal of Executive from or any failure to
          reappoint or reelect Executive to such position, except in connection
          with the termination of Executive's service as an officer for Cause,
          or as a result of Executive's death or inability to perform the
          essential functions of his job, with or without a reasonable
          accommodation, or (2) a reduction (other than for Cause) by Employer
          in Executive's Base Compensation as of the date hereof, or (3) a
          relocation of Executive's assigned place of employment outside the
          Dallas/Fort Worth Standard Metropolitan Statistical Area without
          Executive's consent, or (4) a Change of Control.

     (g)  Upon the termination of this Agreement by Employer with Cause or by
     Executive without Good Reason, Employer shall have the option, exercisable
     within ninety (90) days after the termination date, to purchase all stock
     of Employer then owned by Executive at fair market value on the date of
     termination, which shall be determined in good faith by the Board. In the
     event that Executive disagrees with the Board's determination of fair
     market value, it shall be determined by an independent certified public
     accountant selected by the Board. Payment for such stock shall, at
     Employer's option, be in cash or by promissory note in the amount of the
     fair market value, bearing interest at 10% annum, and payable in no more
     than three equal annual installments of principal, together with accrued
     interest.

                                       -4-
<Page>

     (h)  Upon the termination of this Agreement by Employer without Cause or by
     Executive with Good Reason, Executive shall have the option, exercisable
     within ninety (90) days after the termination date, to require Employer to
     purchase all stock of Employer then owned by Executive, the valuation and
     payment terms to be determined as set out in (f) above. Executive (or his
     duly designated personal representative or executor) shall have the same
     option to require Employer to purchase Executive's stock in the event of
     Executive's death or permanent disability. Such option must be exercised by
     notice to Employer within ninety (90) days after Executive's death or
     permanent disability.

6.   CHANGE IN CONTROL IS DEFINED AS:

          For purposes of this Plan, a Change in Control shall be deemed to have
     occurred if

     (a)  a tender offer (or series of related offers) shall be made and
     consummated for the ownership of 50% or more of the outstanding voting
     securities of the Employer;

     (b)  the Employer shall be merged or consolidated with another corporation
     and as a result of such merger or consolidation less than 50% of the
     outstanding voting securities of the surviving or resulting corporation
     shall be owned in the aggregate by the former shareholders of the Company,
     any employee benefit plan of the Company or its subsidiaries, and their
     affiliates;

     (c)  the Employer shall sell substantially all of its assets to another
     corporation that is not wholly owned by the Company; or

     (d)  a Person (as defined below) shall acquire 50% or more of the
     outstanding voting securities of the Company (whether directly, indirectly,
     beneficially or of record).

          For purposes of this Section, ownership of voting securities shall
     take into account and shall include ownership as determined by applying the
     provisions of Rule 13d-3(d)(I)(i) (as in effect on the date hereof) under
     the Exchange Act. Also for purposes of this Section 6(b), Person shall have
     the meaning given in Section 3(a)(9) of the Exchange Act, as modified and
     used in Sections 13(d) and 14(d) thereof; however, a Person shall not
     include (1) the Employer or any of its subsidiaries; (2) a trustee or other
     fiduciary holding securities under an employee benefit plan of the Company
     or any of its subsidiaries; (3) an underwriter temporarily holding
     securities pursuant to an offering of such securities; or (4) a corporation
     owned, directly or indirectly, by the shareholders of the Employer in
     substantially the same proportion as their ownership of stock of the
     Company.

7.   NON-INTERFERENCE, NON-SOLICITATION AND NON-COMPETITION COVENANTS

     (a)  Pursuant to this Agreement, Executive has agreed to become Senior Vice
     President and Chief Financial Officer of Employer and to comply with a
     non-disclosure

                                       -5-
<Page>

     provision in Section 8. Executive recognizes and acknowledges that he will
     be given access to certain of Employer's Confidential Information (as
     hereafter defined in Section 9(a)), and have access to and authority to
     develop relationships with customers of Employer because of his position
     and status as an Employer's Senior Vice President and Chief Financial
     Officer, which he would not otherwise attain. In consideration of the
     foregoing, Executive agrees to comply with the terms of this Section 7.

     (b)  The restraints imposed by this Section 7 shall apply during any period
     that Executive continues to receive payment of Base Compensation hereunder,
     and for a period of one year thereafter (the "Restricted Period").
     Notwithstanding any other provision in this Agreement, if Employer
     terminates Executive's employment under Section 5(e) following a Change in
     Control, the Restricted Period shall extend for a period ending one year
     after the Payout Period. In the event that any Court having jurisdiction
     should find that the Restricted Period is so long and/or the scope
     (distance) (as set forth below) is so broad as to constitute an undue
     hardship on Executive, then, in such event only, the Restricted Period and
     area limitations shall be valid for the maximum time and area for which
     they could be legally made and enforced.

     (c)  During the Restricted Period, Executive shall not, as an executive
     (other than an executive of Employer or an affiliate thereof), employee,
     employer, stockholder, officer, director, partner, consultant, advisor,
     proprietor, lender, provider of capital or other ownership, operational or
     management capacity, directly or indirectly, (i) solicit or hire any
     employee of Employer or otherwise interfere with or disrupt the employment
     relationship between Employer and any employee, (ii) solicit or do business
     with (a) Employer's customers with whom Employer did business while
     Executive was employed under this Agreement or (b) individuals or entities
     whom Executive met as a result of his position with Employer while
     Executive was employed under this Agreement, that results in competition
     with Employer in any county, parish or other comparable jurisdiction within
     a state, province or nation located in North America in which any of such
     customers have operations (other than customers whose business relationship
     with Employer has terminated for at least 90 days) or in which Employer has
     conducted business while Executive was employed under this Agreement
     (collectively, the "Restricted Area"), or (iii) be associated with any
     entity engaged in the business of non-hazardous waste disposal in the
     Restricted Area that results in competition with Employer (but excluding
     association due to ownership of less than 5% of the outstanding securities
     of any such entity).

     (d)  Executive expressly recognizes and agrees that the restraints imposed
     by this Section 7 are (i) reasonable as to time, geographic limitation and
     scope of activity to be restrained; (ii) reasonably necessary to the
     enjoyment by Employer of the value of its assets and to protect its
     legitimate interests; and (iii) not oppressive. Executive further expressly
     recognizes and agrees that the restraints imposed by this Section 7
     represent a reasonable and necessary restriction for the protection of the
     legitimate interests of Employer, that the failure by the Executive to
     observe and comply with the covenants and agreements in this Section 7 will
     cause irreparable harm to Employer, that it is and

                                       -6-
<Page>

     will continue to be difficult to ascertain the harm and damages to Employer
     that such a failure by the Executive would cause, that the consideration
     received by the Executive for entering into these covenants and agreements
     is fair, that the covenants and agreements and their enforcement will not
     deprive Executive of his ability to earn a reasonable living in the waste
     disposal field or otherwise, and that Executive has acquired knowledge and
     skills in his field that will allow him to obtain employment without
     violating these covenants and agreements. Executive further expressly
     acknowledges that he has been encouraged to and has consulted independent
     counsel, and has reviewed and considered this Agreement with that counsel
     before executing this Agreement.

8.   MEMORANDA, NOTES, RECORDS, ETC. - All memoranda, notes, records, customer
     lists or other documents made or compiled by Executive or otherwise made
     available to him concerning the business of Employer or its subsidiaries or
     affiliates shall be Employer's property and shall be delivered to Employer
     upon the expiration or termination of Executive's employment hereunder or
     at any other time upon request by Employer, and Executive shall retain no
     copies of those documents. Executive shall never at any time have or claim
     any right, title or interest in any material or matter of any sort prepared
     for or used in connection with the business or promotion of Employer.

9.   NONDISCLOSURE

     (a)  Executive hereby acknowledges that in connection with his employment
     by Employer he will be exposed to and may obtain certain information
     (including, without limitation, procedures, memoranda, notes, records and
     customer and supplier lists whether such information has been or is made,
     developed or compiled by Executive or otherwise has been or is made
     available to him) regarding the business and operations of Employer and its
     subsidiaries or affiliates. Executive further acknowledges that such
     information and procedures are unique, valuable, considered trade secrets
     and deemed proprietary by Employer. For purposes of this Agreement, such
     information and procedures shall be referred to as "Confidential
     Information," except that the following shall not be considered
     Confidential Information: (i) information disclosed on a non-confidential
     basis to third parties by Employer (but not by Executive in violation of
     this Agreement), (ii) information released from confidential treatment by
     written consent of Employer, and (iii) information lawfully available to
     the general public.

     (b)  Executive agrees that all Confidential Information is and will remain
     the property of Employer. Executive further agrees, for the duration of the
     Term and thereafter, to hold in the strictest confidence all Confidential
     Information, and not to, directly or indirectly, duplicate, sell, use,
     lease, commercialize, disclose or otherwise divulge to any person or entity
     any portion of the Confidential Information or use any Confidential
     Information for his own benefit or profit or allow any person, entity or
     third party, other than Employer and authorized Executives of the same, to
     use or otherwise gain access to any Confidential Information.

     (c)  It is the intention of the parties that to the extent any Confidential
     Information may constitute a "trade secret" as defined by Texas common law,
     then, in addition to the

                                       -7-
<Page>

     remedies set forth in this Agreement, Employer may elect to bring an action
     against Executive in the case of any actual or threatened misappropriation
     of any such trade secret by Executive.

     (d)  Regardless of whether any of the Confidential Information or any of
     the items set forth in Section 8 and this Section 9 constitute a trade
     secret as defined by Texas common law, Executive expressly recognizes and
     agrees that the restrictions contained in Section 8 of this Agreement and
     this Section 9 represent a reasonable and necessary protection of the
     legitimate interests of Employer, that his failure to observe and comply
     with his covenants and agreements in those Sections will cause irreparable
     harm to Employer, that it is and will continue to be difficult to ascertain
     the harm and damages to Employer that such a failure by Executive could
     cause, and that a remedy at law for such failure by Executive will be
     inadequate.

10.  ENFORCEMENT - The parties hereto recognize that the covenants of Executive
     hereunder are special, unique and of extraordinary character. Accordingly,
     it is the intention of the parties that, in addition to any other rights
     and remedies which Employer may have in the event of any breach of said
     Sections, Employer shall be entitled, and hereby is expressly and
     irrevocably authorized by Executive, inter alia, to demand and obtain
     specific performance, including without limitation temporary and permanent
     injunctive relief, and all other appropriate equitable relief against
     Executive in order to enforce against Executive, or in order to prevent any
     breach or any threatened breach by Executive of, the covenants and
     agreements contained herein. In case of any breach of this Agreement,
     nothing herein contained shall be construed to prevent Employer from
     seeking such other remedy in the courts as it may elect or invoke.

11.  DELEGATION OF DUTIES AND ASSIGNMENT OF RIGHTS

     (a)  Executive may not delegate the performance of any of his obligations
     or duties hereunder, or assign any rights hereunder, without the prior
     written consent of Employer. Any such purported delegation or assignment in
     the absence of such written consent shall be null and void with no force or
     effect. Notwithstanding the foregoing, nothing herein shall prevent
     Executive from delegating ministerial tasks to assistants of the type that
     are normally assigned by executives to assistants.

     (b)  Employer may not assign this Agreement except with the prior written
     consent of Executive, except that Employer may without Executive's consent
     assign all of its rights and obligations under this Agreement to the person
     or entity acquiring a majority of the assets or outstanding stock of IESI
     or pursuant to a merger or consolidation of IESI. In the event of such an
     assignment by Employer, each reference in this Agreement to Employer shall
     include the assignee from and after the date of such assignment.

     (c)  In the event of a valid assignment pursuant to this Section 11, this
     Agreement shall be binding on and inure to the benefit of the parties
     hereto and their respective heirs,

                                       -8-
<Page>

     representatives, successors and permitted assigns and any receiver, trustee
     in bankruptcy or representative of the creditors of each such person.

12.  SURVIVAL OF COVENANTS - Notwithstanding anything contained in this
     Agreement, upon the expiration of the Term or the Restricted Period, as
     applicable, or in the event Executive's employment is terminated for any
     reason whatsoever, the covenants and agreements of Executive contained in
     Sections 7 (to the extent set forth therein), 8, 9, 10 and 12 and the
     covenants of Employer contained in Section 5 hereof shall survive any such
     expiration or termination and shall not lapse except as provided herein.

13.  WARRANTY - Executive does hereby warrant that he has not taken any action,
     and covenants that during the Term of this Agreement, or the Restricted
     Period, as applicable, he shall take no such action, that constitutes or
     will constitute a breach of any agreement concerning confidential
     information and trade secrets, confidentiality, solicitation or
