Indebtedness represented by that amount of the IESI Senior Subordinated Notes not tendered by the holders thereof pursuant to the Tender Offer (excluding the US Notes and US Credit Facility, the “IESI Indebtedness”). Such IESI Indebtedness is expected to consist of Indebtedness under the IESI Senior Subordinated Notes and the IESI Credit Facility.

2.2.22. Regarding the Other Pool Units, the Surviving Corporation shall:

2.2.22.1. transfer a number of Units equal to the Net Option Pool Number to the respective holders of the 1999 Options, the Sowell Warrant and the Boisture Warrant according to their entitlements as determined pursuant to Section 2.2.18 and certified pursuant to Section 2.2.23;

2.2.22.2. subject to the approval of shareholders of IESI prior to the Closing representing at least 75% of the aggregate voting power of IESI (within the meaning of Section 280G of the Code and the regulations promulgated thereunder), transfer a number of Units equal to the Bonus Pool Number to such individuals as the compensation committee of the board of directors of IESI shall have instructed prior to Closing; and

2.2.22.3. subject to the approval of shareholders of IESI prior to the Closing representing at least 75% of the aggregate voting power of IESI (within the meaning of Section 280G of the Code and the regulations promulgated thereunder), transfer a number of Units equal to the Special Bonus Pool Number to the parties to the Forfeiture Agreements pursuant to their respective New Employment Agreements as instructed by the compensation committee of the board of directors of IESI prior to the Closing.

2.2.23. After the close of business on the day immediately prior to the Closing Date, IESI shall deliver to the Fund a certificate (the “Allocation Certificate”) signed by an officer of IESI, setting forth (i) the applicable Unit Percentages with respect to each class of IESI Common Stock and each series of IESI Preferred Stock, (ii) the Share Pool Number and the number of Other Pool Units, (iii) the names of the Persons entitled to the Other Pool Units and their respective entitlements, and (iv) a certification that upon delivery of such Units the relevant 1999 Options and the Boisture Warrant and the Sowell Warrant shall be terminated without the requirement of any further action by any Person.

Post-Merger Steps

2.2.24. Immediately after the Merger, the Fund shall contribute its IESI Common Shares to Fund Newco, and in consideration therefor Fund Newco shall issue to the Fund additional Fund Newco common shares. IESI and the Fund shall, acting reasonably, determine whether or not IESI has accumulated earnings and profits for tax purposes as of December 31, 2004. If it so determined that IESI has such accumulated earnings and profits in excess of US$100,000, then the transaction provided for in the first sentence of this Section 2.2.24 shall be effected immediately before the Merger and

the Parties shall take such additional actions as may be reasonably requested by any Party to effect this change.

Other

2.2.25. The parties thereto shall execute and deliver a Securityholders’ Agreement consistent with the form of the draft attached as Exhibit 2.2.25 (the “Securityholders’ Agreement”).

2.2.26. The Fund shall use its reasonable commercial efforts to cause the requirements set forth in the Amended and Restated Declaration of Trust as regards the Trustees to be effected by the appointment of the individuals set forth on Exhibit 2.2.26.

2.2.27. At or following the Closing, the Fund shall cause the Surviving Corporation to make (i) payments in cash in the aggregate amount of US$3,360,000 pursuant to and at the times specified in the New Employment Agreements with Messrs. Apuzzi, Cowee, Flood and LoVerde and (ii) fiscal 2004 cash bonus payments to IESI employees in the aggregate amount of at least US$1,600,000 pursuant to the terms of the associated cash bonus plan.

2.3 Aggregate Unit Number Adjustment

In the event the Offering is completed at an actual price per Unit (the “Actual Offering Price”) which is less than Cdn$25.63 per Unit (the “Signing Unit Price”), the Aggregate Unit Number shall be decreased as shown in Exhibit 2.3 (for greater certainty, the Aggregate Unit Number shall never be greater than 23,307,185); provided that if the Fund has completed the acquisition of another business at any time after the date hereof and before the completion of the Offering, the amounts set forth in Exhibit 2.3 shall be adjusted upwards (but in no event shall the Aggregate Unit Number be greater than 23,307,185) in order that the simple annualized accretion in the Fund’s free cash flow available for distribution per Unit outstanding on the date hereof reflects the pro forma effect of such acquisition(s) on a basis and in a manner consistent with the methodologies used to prepare Exhibit 2.3.

2.4 Officers and Directors of Surviving Corporation

The officers of IESI immediately prior to the Effective Time shall be the officers of the Surviving Corporation, until the earlier of their resignation or removal or otherwise ceasing to be an officer or until their respective successors are duly elected and qualified, as the case may be. The directors of the Surviving Corporation shall be the individuals set forth on Exhibit 2.4 until the earlier of their resignation or removal or their otherwise ceasing to be a director or until their respective successors are duly elected and qualified.

2.5 Appraisal Remedy

Notwithstanding anything in this Agreement to the contrary, shares of IESI Common Stock and IESI Preferred Stock issued and outstanding immediately prior to the Effective Time held by a holder (if any) who has the right to demand payment for and properly demands an appraisal of such shares in accordance with Section 262 of the DGCL (or any

successor provision) (“Dissenting Shares”) shall not be converted into a right to receive Participating Preferred Shares but shall only have the rights set forth in Section 262 of the DGCL (or any successor provision) unless such holder fails to perfect or effectively withdraws or otherwise loses such holder’s right to such payment or appraisal, if any, with respect to such Dissenting Shares in accordance with Section 262 of the DGCL. If, after the Effective Time, such holder fails to perfect or effectively withdraws or loses any such right to appraisal, each such share of such holder shall not be treated as a Dissenting Share for purposes of this Agreement and shall thereupon be deemed to have been converted as of the Effective Time into the right to receive Participating Preferred Shares in accordance with Section 2.2.17, without interest. IESI shall give prompt notice to the Fund of any demands received by IESI for appraisal of shares of IESI Common Stock or IESI Preferred Stock, withdrawals of such demands and any other instruments served pursuant to the DGCL received by IESI, and the Fund shall have the right to participate in and direct all negotiations and proceedings with respect to such demands.

2.6.2. Exchange Procedure for Stock. Within a reasonable period prior to the Closing Date, IESI shall mail to each holder of record of a certificate or certificates of which immediately prior to the Effective Time represented outstanding shares of IESI Common Stock or IESI Preferred Stock (the “Certificates”) whose shares were converted into the right to receive such holder’s ratable portion of the Participating Preferred Shares in accordance with Section 2.2.17: (i) a letter of transmittal provided by the Fund and reasonably satisfactory to IESI (the “Letter of Transmittal”) and (ii) instructions as specified by the Fund for use in effecting the surrender of the Certificates in exchange for such Participating Preferred Shares. After the Effective Time, upon surrender of a Certificate for cancellation to the Surviving Corporation or to such other agent or agents as may be appointed by the Surviving Corporation, together with the Letter of Transmittal, duly completed and executed, and such other instructions, the holder of such Certificate shall be entitled to receive in exchange therefor, and the Surviving Corporation shall promptly distribute to such holder, the number of Participating Preferred Shares that such holder is entitled to receive pursuant to Section 2.2.17 and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of shares of IESI Common Stock or IESI Preferred Stock that is not registered in the transfer records of the Surviving Corporation, payment may be made to a Person other than the Person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such

Certificate or establish to the satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.6.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender a ratable portion of the Participating Preferred Shares into which the shares of IESI Common Stock or IESI Preferred Stock theretofore represented by such Certificate shall have been converted pursuant to Section 2.2.17, together with all accrued distributions thereon.

2.6.3. No Further Ownership Rights. The Participating Preferred Shares delivered upon the surrender of the shares of IESI Common Stock or IESI Preferred Stock in accordance with the terms hereof shall be deemed to have been delivered in full satisfaction of all rights pertaining to such shares. There shall be no further registration or transfers on the stock transfer books of the Surviving Corporation of the shares of IESI Common Stock or IESI Preferred Stock which were outstanding immediately prior to the Effective Time.

2.6.4. No Liability. Notwithstanding anything to the contrary in this Section 2.6, none of the Purchasers nor the Surviving Corporation shall be liable to any holder of shares of IESI Common Stock or IESI Preferred Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law, rule, regulation, statute, order, judgment or decree.

2.6.5. Lost, Stolen or Destroyed Certificates. In the event any Certificate representing shares of IESI Common Stock or IESI Preferred Stock shall have been lost, stolen or destroyed, the Surviving Corporation shall deliver the Participating Preferred Shares in exchange for such lost, stolen or destroyed Certificate upon the making of an affidavit of that fact by the holder thereof; provided, however, that the Surviving Corporation may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificate to deliver an indemnity (with or without a bond in support thereof and in such sum as it may reasonably direct) against any claim that may be made against the Surviving Corporation with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.6.6. No Fractional Shares. No certificates representing fractional shares of Participating Preferred Stock shall be issued. In lieu of such issuance of fractional shares, the Surviving Corporation shall pay each holder of certificates representing shares of IESI Common Stock or IESI Preferred Stock which would otherwise entitle such holder to receive fractional shares of Participating Preferred Stock an amount in cash equal to the product of (i) the portion of a single share of Participating Preferred Stock that such holder would be entitled to receive were fractional shares of Participating Preferred Stock permitted to be issued hereunder and (ii) the value of a single share of Participating Preferred Stock, based on the product of the Exchange Ratio as of Closing and the Closing Unit Value.

with, any Person in response to an unsolicited written bona fide Acquisition Proposal that is submitted to the Fund by such Person (and not withdrawn) and that the Trustees determine in good faith is reasonably likely to lead to a Superior Proposal if (1) neither the Purchasers nor any of their Representatives shall have breached or taken any action inconsistent with any of the provisions set forth in this Section 5.6.1 in a manner that directly or indirectly has led or contributed to the submission of such Acquisition Proposal, (2) the Trustees conclude in good faith, after considering the written advice of their outside legal counsel, that such action is required in order for the Trustees to comply with their fiduciary obligations to the Unitholders under applicable law, (3) at least two Business Days prior to furnishing any such non-public information to, or entering into discussions with, such Person, the Fund gives IESI written notice of the identity of such Person and of the Fund’s intention to furnish non-public information to, or enter into discussions with, such Person, and the Fund receives from such Person an executed Standard Confidentiality Agreement, and (4) at the same time as it furnishes any such information to such Person, the Fund furnishes such non-public information to IESI.

5.6.2. The Fund shall promptly inform IESI if any BFI Entity, any of their Representatives or any other Person receives, after the date hereof, any proposal or inquiry in respect of any such transaction described in Section 5.6.1. In addition, the Fund shall promptly (and in no event later than 24 hours after receipt of any Acquisition Proposal or any request for non-public information in connection with an Acquisition Proposal) advise IESI in writing of any Acquisition Proposal or any request for non-public information relating to any of the BFI Entities in connection with an Acquisition Proposal (including the identity of the Person making or submitting such Acquisition Proposal and the terms thereof) that is made or submitted by any Person prior to Closing and provide IESI with a copy of such Acquisition Proposal or request for non-public information. The Fund shall keep IESI fully informed in a timely manner with respect to the status of any such Acquisition Proposal, inquiry, indication of interest or request and any modification or proposed modification thereto.

5.7 Right to Match

5.7.1. The Fund shall not accept, approve, recommend or enter into any agreement in respect of an Acquisition Proposal (other than a Standard Confidentiality Agreement to the extent permitted by Section 5.6.1) unless (i) it has provided IESI with a copy of the Acquisition Proposal document which the Trustees have determined would be a Superior Proposal, and (ii) ten Business Days shall have elapsed from the later of the date IESI received written notice of the Trustees’ proposed determination to accept, approve, recommend or enter into an agreement in respect of such Acquisition Proposal, and the date IESI receives a copy of the Acquisition Proposal.

5.7.2. During such ten Business Day period, the Fund acknowledges that IESI shall have the opportunity, but not the obligation, to propose to amend the terms of this Agreement and the Transactions. The Trustees will review any proposal by IESI to amend the terms of this Agreement in good faith in order to determine, in its discretion in the exercise of its fiduciary duties, whether IESI’s proposal upon acceptance by the Fund would result in the Acquisition Proposal no longer being a Superior Proposal. If the Trustees so determine, the Fund will enter into an amended agreement with IESI reflecting IESI’s amended proposal. If the Trustees continue to believe, in good faith and after consultation with financial advisors and outside counsel that the Acquisition Proposal is nonetheless a Superior Proposal and therefore rejects IESI’s amended proposal, the Fund will be entitled to provide notice to IESI that it is terminating this Agreement pursuant to Section 8.2.5 upon payment by the Fund to IESI of the Break-up Fee.

5.7.3. The Fund also acknowledges and agrees that each successive modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of the requirement under Section 5.7.2 to initiate an additional ten Business Day notice period.

Agreement (limited to breaches, or failures to perform or comply, occurring at or before the Closing) other than with respect to matters addressed in clauses (ii) through (vi)); (ii) any third-party advisor fees and expenses and other out-of-pocket expenses incurred by any IESI Entity in connection with the negotiation and finalization of this Agreement and the Transaction Documents and the completion of the Transactions if and to the extent that such fees and expenses are (x) materially more in the aggregate than the estimate of third-party advisor fees and expenses provided by IESI to the Fund prior to the date of this Agreement and (y) unreasonable; (iii) (A) any inaccuracy or breach of Section 3.3.1 (but solely with respect to equity securities of IESI), (B) any inaccuracy or breach of the first sentence of Section 3.4 (but solely with respect to options and warrants to purchase, or securities convertible into or exchangeable for, equity securities of IESI) and (C) any claim by any holder before Closing of any equity securities of IESI, or any options or warrants to purchase, or securities convertible into or exchangeable for, equity securities of IESI that the consideration received by them in the Merger as set forth on the Allocation Certificate was less than they were entitled to receive pursuant to the terms of such securities or any plan or agreement of IESI under which such securities were issued; (iv) any Tantalo Purchaser Amount (as defined below); (v) any Seneca Meadows Purchaser Tax Amount (as defined below); and (vi) any Excess Parachute Amount (as defined below) (in each case a “Purchaser Loss”), in each case by (and only by) reducing the number of Escrow Shares in accordance with Section 6.4.

6.1.2. The Purchaser Indemnified Party shall promptly after it becomes aware of any circumstance which might reasonably be expected to become the subject matter of a claim to be made by it under Section 6.1 (a “Purchaser Claim”) including any action, lawsuit, proceeding, investigation or other claim against any BFI Entity by a third party (for purposes of this section, “Third-Party Claim”), advise the Owner Representative of such circumstance, and shall provide the Owner Representative, from time to time, such information as the Owner Representative shall reasonably request in connection therewith; provided that any delay or failure to so advise the Owner Representative shall not affect the rights of the Purchaser Indemnified Party hereunder except to the extent that the Owners are prejudiced by such delay or failure. The Owner Representative shall be entitled to but shall not be obligated to assume exclusive control and discretion in the conduct of the defence of any Third-Party Claim; provided that the Purchaser Indemnified Party shall be permitted to retain one separate counsel, at the Owners’ expense (satisfied exclusively out of the Cap Amount pursuant to Section 6.1.4) in respect of a Third-Party Claim (i) for which the Purchaser Indemnified Party shall have been advised by counsel that there are one or more legal or equitable defences available to the Purchaser Indemnified Party and, in the reasonable opinion of the Purchaser Indemnified Party, counsel for the Owners could not adequately represent the interests of the Purchaser Indemnified Party because such interests could be in conflict with those of the Owners; or (ii) for which the Owner Representative shall not have assumed the defence within 20 days of receiving notice thereof; and provided further that in the event that the Purchaser Indemnified Party shall in good faith determine that the conduct of the defence of the Third-Party Claim or any proposed settlement of the Third-Party Claim by the Owner Representative may be expected to affect adversely the conduct of the IESI Business or BFI Business in any material respect, the Purchaser Indemnified Party shall have the right, at all times, to take over and assume control over the Third-Party Claim at

the Owners’ expense (satisfied exclusively pursuant to Section 6.1.4). The Owner Representative shall not settle or compromise any Third-Party Claim or allow a default or consent to entry of any judgment with respect thereto without obtaining an unqualified and full release of the Purchaser Indemnified Party in connection therewith. The Purchaser Indemnified Party shall also have the right to employ separate counsel in any action brought in respect of any matter which is or may be the subject of a Third-Party Claim for indemnification hereunder, and shall have the right to participate in the defence thereof, but the fees and expenses related thereto, including fees and expenses of counsel, shall be at the expense of the Purchaser Indemnified Party except as otherwise permitted by the second sentence of this Section 6.1.2. The assumption of control and conduct of the defence by the Owner Representative of any matter which might reasonably be expected to become a Third-Party Claim shall not constitute an acknowledgement by the Owner Representative of any Qualifying Purchaser Loss, the procedures for determining such Qualifying Purchaser Loss being set forth in Section 6.5.

6.1.3. Notwithstanding anything to the contrary contained herein, in the event of a Purchaser Loss, the number of Escrow Shares shall not be reduced in accordance with Section 6.4:

6.1.3.2. after such time as the aggregate of all indemnifiable Purchaser Losses exceeds an amount equal to (i) at any time prior to the first anniversary of the Closing Date (the “First Anniversary”), the value of the Closing Escrow Shares and (ii) at any time following the First Anniversary but prior to the second anniversary of the Closing Date, the value of the Second Year Cap Shares (as applicable, the “Cap Amount”);

6.1.3.3. unless such claim is asserted in writing on or prior to the Expiration Date;

6.1.3.4. unless and until such time as such Purchaser Loss is determined to be a Qualifying Purchaser Loss in accordance with Section 6.5; and

6.1.3.5. in the case of a breach of Section 3.28 (Prospectus Disclosure) or Section 3.29 (Proxy Materials) or of the agreements set forth in Sections 5.8.2 and 5.10.3, unless and solely to the extent that such Purchaser Loss involves Losses arising from a claim against the Fund or its Affiliates by a Unitholder under the Prospectus or Proxy Materials, as the case may be, or by an underwriter under the Underwriting Agreement entered into in connection with the Offering.

6.1.4. In the event that the Purchaser Indemnified Party retains separate counsel, or takes over and assumes control over a Third-Party Claim, at the Owners’ expense pursuant to and in accordance with Section 6.1.2 (it being understood and agreed that such expense shall only be borne by the Owners if it is in respect of Qualifying Purchaser Loss), upon written notice from the Purchaser Indemnified Party to the Owner Representative of the amount of any such reimbursable expenses, a number of Escrow Shares equal to the product of (i) the quotient of the applicable amount of reimbursable expenses over the Market Price Per Unit on the date of delivery of such notice and (ii) the applicable Exchange Ratio, shall be transferred to IESI and cancelled.

6.2 Indemnification of the Owners

6.2.1. From and after the Closing Date and subject to Section 6.2.3 and Section 6.3 and in accordance with Section 6.2.2, the Owners (collectively, the “Owner Indemnified Parties”) shall be indemnified against and in respect of any and all Losses caused by or resulting or arising from (i) any inaccuracy in, any breach of, or any failure to perform or comply with, any of the Purchasers’ representations, warranties or agreements contained in this Agreement (limited to breaches, or failures to perform or comply, occurring at or before the Closing) (other than with respect to any matter addressed in clauses (ii) through (v)); (ii) any third party advisor fees and expenses and other out-of-pocket expenses incurred by any BFI Entity in connection with the negotiation and finalization of this Agreement and the Transaction Documents and the completion of the Transactions if and to the extent that such fees and expense are (x) materially more in the aggregate than the estimate of third party advisor fees and expenses provided by the Fund to IESI prior to the date of this Agreement and (y) unreasonable; (iii) an inaccuracy or breach of Section 4.3.1 (but solely with respect to the Participating Preferred Shares and ownership interests in the Fund); (iv) any Tantalo Owner Amount (as defined below); and (v) any Seneca Meadows Owner Tax Amount (as defined below) (in each case an “Owner Loss”), in each case by (and only by) the Fund issuing Units (or, at its option, paying cash) to the Owners in accordance with Section 6.4.

6.2.2. The Owner Representative, on behalf of any of the Owner Indemnified Parties shall promptly after any of them becomes aware of any circumstance which might reasonably be expected to become the subject matter of a claim to be made by any of them under Section 6.2 (an “Owner Claim”) including any action, lawsuit, proceeding, investigation or other claim against any of them or the Fund by a third party (for purposes of this section, “Third-Party Claim”), advise the Fund of such circumstance, and shall provide the Fund, from time to time, such information as the Fund shall reasonably request in connection therewith; provided that any delay or failure to so advise the Fund shall not affect the rights of the Owner Indemnified Parties hereunder except to the extent that the Fund is prejudiced by such delay or failure. The Fund shall have exclusive control and discretion in the conduct of the defence of any Third-Party Claim; provided that the Owner Representative shall be permitted to retain one separate counsel on behalf of the Owners, at the Fund’s expense in respect of a Third-Party Claim (satisfied exclusively out of the Cap Amount) (i) for which the Owner Representative shall have been advised by counsel that there are one or more legal or equitable defences available

to the Owners and, in the reasonable opinion of the Owner Representative, counsel for the Fund could not adequately represent the interests of the Owners because such interests could be in conflict with those of the Fund or (ii) the Fund shall not have assumed the defence within 20 days of receiving notice thereof. The Fund shall not settle or compromise any Third-Party Claim or allow a default or consent to entry of any judgment with respect thereto without obtaining an unqualified and full release of the Owners in connection therewith. The Owner Representative shall also have the right to employ separate counsel in any action brought in respect of any matter which is or may be the subject of a Third-Party Claim for indemnification hereunder, and shall have the right to participate in the defence thereof, but the fees and expenses related thereto, including fees and expenses of counsel, shall be at the expense of the Owners except as otherwise permitted by the second sentence of this Section 6.2.2. The assumption of control and conduct of the defence by the Fund of any matter which might reasonably be expected to become Third-Party Claim shall not constitute an acknowledgement by the Fund of any Qualifying Owner Loss, the procedures for determining such Qualifying Owner Loss being set forth in Section 6.5.

6.2.3. Notwithstanding anything to the contrary contained herein, in the event of a Owner Loss, the Fund shall not be required to issue Units (or, at its option, pay cash) in accordance with Section 6.4:

6.2.3.1. except with respect to any Owner Loss described in clauses (ii) through (v) of Section 6.2.1, until such time as the aggregate of all indemnifiable Owner Losses exceeds the Basket Amount, at which time, subject to Section 6.2.3.2, all such amounts shall be indemnifiable hereunder, excluding the Basket Amount;

6.2.3.3. unless such claim is asserted in writing on or prior to the Expiration Date;

6.2.3.4. unless and until such time as such Owner Loss is determined to be a Qualifying Owner Loss in accordance with Section 6.5; and

6.5 Claim Procedures; Determination of Net Loss

The procedure for determining Purchaser Losses and Owner Losses for purposes of Section 6.4 shall be as follows:

6.5.1. If from time to time, the Fund or the Owner Representative (the party claiming a loss, a “Claiming Party”) determines in good faith that there has been a Purchaser Loss or an Owner Loss, as the case may be, such Claiming Party shall provide written notice to the Owner Representative (in the case of a claimed Purchaser Loss) or the Fund (in the case of a claimed Owner Loss), as the case may be (such party, the “Subject Party”), describing the nature of the claim for such loss, the amount thereof, and the provisions in this Agreement on which such claim for loss is based and, to the extent applicable, the relevant Section of the Prospectus or Proxy Materials on which such claim is based (such notice, a “Claim Notice”).

6.5.2. If the Claiming Party does not receive written objection to a claim pursuant to Section 6.5.1 within 15 Business Days after delivery of the applicable Claim Notice, the loss claimed by the Claiming Party shall be deemed to be approved and accepted by the relevant Subject Party and shall be considered a “Qualifying Purchaser Loss” (if the Claiming Party is the Fund) or a “Qualifying Owner Loss” (if the Claiming Party is the Owner Representative), as the case may be, for purposes of Section 6.4. Qualifying Purchaser Losses and Qualifying Owner Losses are referred to collectively as “Qualifying Losses.”

6.5.3. If within the 15 Business Day period following delivery of the relevant Claim Notice the Claiming Party receives from the relevant Subject Party a written objection to such Claiming Party’s claim for loss, specifying the nature of and grounds for such objection, then such claim for loss shall be deemed an “Open Purchaser Claim for Loss” (if the Claiming Party is the Fund) or an “Open Owner Claim for Loss” (if the Claiming Party is the Owner Representative), as the case may be, for purposes of Section 6.4. Open Purchaser Claim for Loss and Open Owner Claim for Loss are referred to collectively as “Open Claim for Loss”.

6.5.4. If the relevant Claiming Party receives a notice of objection pursuant to Section 6.5.3, the relevant Claiming Party and Subject Party shall negotiate in good faith to resolve any such objections and, to the extent they agree that a Loss is indemnifiable pursuant to Section 6.1 or Section 6.2, as the case may be, the agreed amount of such Loss shall be considered a Qualifying Loss for purposes of Section 6.4. If the Claiming Party and the Subject Party do not reach a final resolution within 20 Business Days after delivery of the notice of objection described in Section 6.5.3, the dispute arising out of or respecting the Claiming Party’s claim for loss and the written objection thereto (under Section 6.5.3) shall be determined by arbitration in accordance with the International Arbitration Rules of the International Centre for Dispute Resolution (“Rules”), subject to

the provisions set forth in Exhibit 6.5.4. If the arbitral tribunal determines that the Subject Party is liable to the Claiming Party for any Loss, the amount of such Loss (which in no event shall be greater than the amount originally claimed by the Claiming Party) shall be considered a Qualifying Loss for purposes of Section 6.4 above.

6.5.5. The calculation of the amount of any indemnifiable Loss and the consequent adjustment of the relative ownership interests of the Owners shall be made such that following indemnification with respect to any such Loss pursuant to this Article VI, the pro forma ownership interest of the Owners (based on the number of Participating Preferred Shares held by such Owners at such time on an As-if-Exchanged Basis) relative to the pro forma ownership of the holders of Units (not including any Participating Preferred Shares on an As-if-Exchanged Basis) shall be increased or decreased, as the case may be, in an amount the value of which equates to the amount of such Loss. In the case of a Qualifying Owner Loss indemnified by the Fund with a cash payment, such cash payment shall be calculated in a manner consistent with the foregoing principle.

6.6 Additional Provisions

6.6.1. Except in the case of fraud, from and after the Closing, the provisions of this Article VI shall be the exclusive basis for the assertion of claims (other than claims for specific performance against) or the imposition of liability on, any Party under this Agreement.

6.6.2. The representations and warranties, covenants and agreements in this Agreement or in any instrument delivered pursuant to this Agreement shall survive until the Expiration Date.

6.6.3. For the avoidance of doubt and subject to Section 6.4.7, upon a dividend payment or distribution made in respect of the Escrow Shares by IESI, IESI shall distribute such dividend or distribution to Owners pro rata on the basis of the ownership percentages set forth on Schedule I of the Securityholders’ Agreement. Each Owner shall be entitled to vote its proportionate number of Escrow Shares until such time as such shares are transferred and cancelled pursuant to Section 6.4.

6.6.4. The Purchaser Indemnified Party and each of the Owner Indemnified Parties shall each use its reasonable commercial efforts to mitigate any Purchaser Loss or any Owner Loss, respectively.

funds recovered from the defendants in the pending cost recovery action with respect to the Tantalo landfill by an IESI Entity after the date hereof and before the Expiration Date plus (B) the good faith best estimate of any additional funds most likely to be recovered from the defendants in the pending cost recovery action with respect to the Tantalo landfill by an IESI Entity thereafter (collectively, the “Tantalo Cost Recovery”).

Subject to the applicable limitations in Section 6.2.3, the Owner Indemnified Parties shall be indemnified pursuant to Section 6.2, to the extent that it is determined in accordance with Section 6.5 that the Seneca Meadows Tax Payments are less than $300,000, for the amount equal to the difference of $300,000 less the amount of the Seneca Meadows Tax Payments (such difference, the “Seneca Meadows Owner Tax Amount”) in accordance with Section 6.4.

6.7.3. As of the Expiration Date (or at any times prior thereto if the applicable matters are then determinable with certainty), the Purchaser Indemnified Party may calculate the sum of: (i) any payment required to be made by any IESI Entity to any of Messrs. Brown, Cowee, Flood, Fowler, Moody, McGee or Peckham (the “Relevant Employees”) pursuant to the terms of Section 2(e) of their respective New Employment Agreements (as executed on the date hereof) to “gross up” such Person for the imposition of the excise tax under Section 4999 of the Code on any “excess parachute payment” (including penalties and interest) paid to such Person in connection with the Transactions

(collectively, “Excise Tax Reimbursements”), plus (ii) provided that no Purchaser Indemnified Party has initiated any discussions or inquiries with any taxing authority with respect to such taxes, any Loss arising solely from a challenge made by a taxing authority and which is associated with the disallowance of any federal income tax deduction of any IESI Entity (and any corresponding state or local tax deduction) under Section 280G of the Code with respect to any “excess parachute payment” (including penalties and interest) made in connection with Transaction-related payments to the Relevant Employees, provided that such Loss shall be reduced to take account of any net Tax benefit obtained by the relevant IESI Entity arising from (A) the incurrence or payment of any such claim or tax and (B) any correlative adjustments or changes in tax treatment that occur as a result of the adjustment or change giving rise to such tax (the “280G Tax Losses”) plus (iii) provided that no Purchaser Indemnified Party has initiated any discussions or inquiries with any taxing authority with respect to such taxes, the good faith best estimate (based upon an assessment of the probability of challenges from taxing authorities, the probability of success of such challenges, and the probability of the amount of the claims which would result therefrom) of the amounts, if any, set forth in clauses (i) and (ii) above which are most likely to be incurred thereafter by any IESI Entity (such estimate together with the Excise Tax Reimbursements and the 280G Tax Losses, collectively, the “Excess Parachute Amount”). The Purchasers agree to vigorously defend any challenges from taxing authorities regarding Excise Tax Reimbursements and 280G Tax Losses, and the Owner Representative shall be entitled to participate therein in the manner and to the extent provided in Section 6.1. Subject to the applicable limitations set forth in Section 6.1.3, the Purchaser Indemnified Party shall be indemnified pursuant to Section 6.1.1 and in accordance with Section 6.4 for the amount of any Excess Parachute Amount determined in accordance with Section 6.5.

6.7.4. If as of the First Anniversary, the Purchaser Indemnified Party or the Owner Representative, in good faith and on a reasonable basis, determines that it is reasonably likely that it will seek indemnification for a Tantalo Purchaser Amount or Tantalo Owner Amount, respectively, or for a Seneca Meadows Purchaser Tax Amount or Seneca Meadows Owner Tax Amount, respectively, or an Excess Parachute Amount in the case of the Purchaser Indemnified Party, such party may declare such claim an Open Purchaser Claim for Loss or Open Owner Claim for Loss, respectively, for the purposes of Sections 6.4.1 and 6.4.2; provided, that such Open Purchaser Claim for Loss or Open Owner Claim for Loss will not be settled in accordance with the provisions of Section 6.5 and will remain an Open Purchaser Claim for Loss or Open Owner Claim for Loss, as applicable, until provided by Section 6.7.1 or 6.7.2, as applicable (any such claim, a “Protective Claim”). In the event that the Purchaser Indemnified Party or the Owner Representative makes a Protective Claim which the other party, in good faith, disputes, the parties shall negotiate in good faith to resolve the dispute, and if the parties do not reach a final resolution within 20 Business Days then the determination as to whether the claim constitutes a valid Protective Claim and the amount thereof shall be determined by arbitration in accordance with the Rules, subject to the provisions set forth in Exhibit 6.5.4.
