(b) Subscription Receipt Certificates may be surrendered for exchange only at the Designated Offices during regular business hours of the Escrow Agent. 2.12 CHARGES FOR EXCHANGE Except as otherwise herein provided, the Escrow Agent may charge to the holder requesting an exchange a reasonable sum for each new Subscription Receipt Certificate issued in exchange for Subscription Receipt Certificate(s). Payment of such charges and reimbursement of the Escrow Agent or the Trust for any and all stamp taxes or governmental or other charges required to be paid shall be made by such holder as a condition precedent to such exchange. 2.13 TRANSFER AND OWNERSHIP OF SUBSCRIPTION RECEIPTS (a) Subject to Sections 2.13(d) and 2.15, there are no restrictions on the transfer of the Subscription Receipts. However, the Subscription Receipts may only be transferred on the register kept at one of the Designated Offices by the holder or his legal representatives or his attorney duly appointed by an instrument in writing. Upon surrender for registration of transfer of Subscription Receipts at one of the Designated Offices and upon compliance with Section 2.15, the Trust shall issue and thereupon the Escrow Agent shall certify and deliver a new Subscription Receipt Certificate of like tenor in the name of the designated transferee. If less than all the Subscription Receipts evidenced by the Subscription Receipt Certificate(s) so surrendered are transferred, the transferor shall be entitled to receive, in the same manner, a new Subscription Receipt Certificate registered in his name evidencing the Subscription Receipts not transferred. However, notwithstanding the foregoing, Subscription Receipts shall only be transferred upon: (i) payment to the Escrow Agent of a reasonable sum for each new Subscription Receipt Certificate issued upon such transfer, and reimbursement of the Escrow Agent or the Trust for any and all stamp taxes or governmental or other charges required to be paid in respect of such transfer; and (ii) such reasonable requirements as the Escrow Agent may prescribe, and all such transfers shall be duly noted in such register by the Escrow Agent. 10 (b) The Trust and the Escrow Agent shall deem and treat the registered owner of any Subscription Receipt as the beneficial owner thereof for all purposes and neither the Trust nor the Escrow Agent shall be affected by any notice to the contrary. (c) The transfer register in respect of Subscription Receipts shall be closed at 4:30 p.m. (Calgary time) at the Designated Office, on the earlier to occur of the Acquisition Date and the Termination Date (subject to settlement). (d) The Escrow Agent shall promptly advise the Trust of any requested transfer of Subscription Receipts. The Trust shall be entitled, and may direct the Escrow Agent, to refuse to recognize any transfer, or enter the name of any transferee, of any Subscription Receipts on the registers referred to in this Article, if such transfer would constitute a violation of the securities laws of any jurisdiction or the rules, regulations or policies of any regulatory authority having jurisdiction. (e) Subject to the provisions of this Agreement and applicable law, a Receiptholder shall be entitled to the rights and privileges attaching to the Subscription Receipts. Either the issue and delivery of Units and the applicable Acquisition Payment, less applicable withholding taxes, as provided in Section 3.3, or the payment of the Subscription Price and the Earned Interest, less applicable withholding taxes, as provided in Section 3.4, all in accordance with the terms and conditions herein contained, shall discharge all responsibilities of the Trust and the Escrow Agent with respect to such Subscription Receipts and neither the Trust nor the Escrow Agent shall be bound to inquire into the title of a Receiptholder or a transferee of Subscription Receipts who surrenders a Subscription Receipt Certificate. 2.14 GLOBAL SUBSCRIPTION RECEIPT (a) Unless the Book-Entry Only System is terminated, Subscription Receipt Certificates will only be issued in the form of a Global Subscription Receipt certificate, which will be registered in the name of and deposited with CDS or its nominee. (b) Unless the Book-Entry Only System is terminated or required to be terminated by applicable law, owners of the beneficial interests in the Subscription Receipts shall not be entitled to have Subscription Receipts registered in their names, shall not receive or be entitled to receive Subscription Receipt Certificates in definitive form and shall not be considered owners or holders thereof under this Agreement or any supplemental agreement except in circumstances where CDS resigns or is removed from its responsibility and the Escrow Agent is unable or does not wish to locate a qualified successor. Beneficial interests in the Global Subscription Receipt will be represented only through the Book-Entry Only System. Transfers of Subscription Receipts between CDS participants shall occur in accordance with CDS' rules and procedures. The Trust shall not have any responsibility or liability for any aspects of the records relating to or payments made by CDS, or its nominee, on account of the beneficial interests in the Subscription Receipts. Nothing herein shall prevent the owners of beneficial interests in the Subscription Receipts from voting such Subscription Receipts using duly executed proxies. (c) All references herein to actions by, notices given or payments made to Receiptholders shall, where Subscription Receipts are held through CDS, refer to actions taken by, or notices given or payments made to, CDS upon instruction from the CDS participants in accordance with its rules and procedures. For the purposes of any provision hereof requiring or permitting actions with the consent of or at the direction of Receiptholders evidencing a specified percentage of the aggregate Subscription Receipts outstanding, such direction or consent may be given by holders of Subscription Receipts acting through CDS and the CDS participants owning Subscription 11 Receipts evidencing the requisite percentage of the Subscription Receipts. The rights of a Receiptholder whose Subscription Receipts are held through CDS shall be exercised only through CDS and the CDS participants and shall be limited to those established by law and agreements between such holders and CDS and the CDS participants upon instructions from the CDS participants. Each of the Escrow Agent and the Trust may deal with CDS for all purposes (including the making of payments) as the authorized representative of the respective Receiptholders and such dealing with CDS shall constitute satisfaction or performance, as applicable, of their respective obligations hereunder. (d) For so long as Subscription Receipts are held through CDS, if any notice or other communication is required to be given to Receiptholders, the Escrow Agent will give such notices and communications to CDS. (e) If CDS resigns or is removed from its responsibility as depository and the Escrow Agent is unable or does not wish to locate a qualified successor, CDS shall surrender the Global Subscription Receipt to the Escrow Agent with instructions for registration of Subscription Receipts in the name and in the amount specified by CDS and the Trust shall issue and the Escrow Agent shall certify and deliver the aggregate number of Subscription Receipts then outstanding in the form of definitive Subscription Receipt Certificates representing such Subscription Receipts. 2.15 NO REGISTRATION IN THE UNITED STATES The Escrow Agent acknowledges that the Subscription Receipts and Units have not been registered under the 1933 Act. Furthermore, in accordance with Section 21 of the Underwriting Agreement, the Trust and the Lead Underwriter acknowledge and agree that the Subscription Receipts have not been offered or sold within the United States nor have any "directed selling efforts" been made, nor will any "directed selling efforts" be made, within the United States by the Underwriters with respect to the Subscription Receipts. 2.16 LISTING OF SUBSCRIPTION RECEIPTS The Trust confirms that the Subscription Receipts will be listed and posted for trading on the Toronto Stock Exchange. 2.17 RIGHT OF RESCISSION (a) If the Prospectus, together with any amendment thereto, contains a misrepresentation (as such term is defined in the SECURITIES ACT (Alberta)) and it was a misrepresentation on the date hereof, purchasers of Subscription Receipts to whom the Prospectus was sent or delivered and who were the original purchasers of the Subscription Receipts (the "ORIGINAL PURCHASERS") shall have a right of action against the Trust for rescission to receive the Subscription Price exerciseable on notice given to the Trust not more than 180 days subsequent to the date hereof. The right of action for rescission is only available to an Original Purchaser either while he or she is a holder of the Subscription Receipts purchased or while he or she is a holder of the Units issuable upon surrender of such Subscription Receipts. (b) In no event shall the Trust be liable under this Section 2.17 if the Original Purchaser purchased the Subscription Receipts with knowledge of the misrepresentation. 12 ARTICLE 3 SATISFACTION OF ISSUANCE RIGHT OR TERMINATION PAYMENT RIGHT 3.1 NOTICE OF ACQUISITION If the Acquisition Time occurs by the Deadline: (a) the Trust shall forthwith cause the Acquisition Notice to be delivered to the Escrow Agent and the Lead Underwriter on behalf of the Underwriters and the Trust shall concurrently deliver to the Escrow Agent, the Irrevocable Transfer Agent Direction and the Escrow Agent will issue the Units issuable pursuant to the Subscription Receipts and make any required payment as provided herein, and (b) the Trust shall issue a press release confirming the Acquisition has been completed and setting out the Acquisition Date and that the underlying Units have been or will be issued to Receiptholders effective as at the Issue Time. 3.2 RELEASE OF FUNDS ON ACQUISITION DATE OR FOR DEPOSIT INTO ESCROW ARRANGEMENT TO CLOSE ACQUISITION (a) If the Escrow Release Condition occurs by the Deadline, the Trust shall be entitled to receive from the Escrow Agent the Proceeds and any Earned Interest thereon, less (i) the amount, if any, required to make the payments set forth in Section 3.3(b); and (ii) the amount required to make the payment set forth in Section 3.7 (collectively, the "RELEASED AMOUNT"). The Escrow Agent shall deliver the Released Amount to or to the order of the Trust as soon as reasonably practicable after it receives the written confirmation that the Escrow Release Condition has been satisfied. (b) In addition, the Trust shall be entitled to receive from the Escrow Agent the Released Amount prior to the satisfaction of the Escrow Release Condition upon the Escrow Agent receiving the following documents before the Deadline: (i) a notice in writing in substantially the form attached hereto as Schedule "D" hereto (the "JOINT NOTICE") signed by the Trust and the Lead Underwriter, on behalf of the Underwriters, (i) confirming that the Trust wishes to deposit the Released Amount into an escrow arrangement (the "ESCROW ARRANGEMENT") with Burnet, Duckworth & Palmer LLP, or such other escrow agent satisfactory to the Trust and the Lead Underwriter, each acting reasonably, (the "ESCROW ARRANGEMENT AGENT") for purposes of closing the Acquisition and such Escrow Arrangement Agent shall provide for the Released Amount to be delivered to or to the order of Anadarko for the purposes of closing the Acquisition and to be returned to the Escrow Agent immediately if the Acquisition does not take place on the date indicated on the Joint Notice, and (ii) directing the Escrow Agent to deliver the Released Amount to the Escrow Arrangement Agent; and (ii) an undertaking substantially in the form attached hereto as Schedule "E" hereto (the "JOINT UNDERTAKING") signed by the Trust and AOG that the Released Amount is being delivered to the Escrow Arrangement Agent for deposit pursuant to the terms of the Escrow Arrangement for purposes of closing the Acquisition and that the Released Amount will be returned to the Escrow Agent immediately if the Acquisition does not take place on the date indicated on the Joint Undertaking, which funds shall be released or returned pursuant to the terms of this Agreement. Upon receipt of such Joint Notice and Joint Undertaking, the Escrow Agent shall promptly deliver the Released Amount to the Escrow Arrangement Agent. Upon the Trust receiving 13 confirmation from the Escrow Arrangement Agent that the Acquisition has closed, the provisions of Section 3.1 shall apply MUTATIS MUTANDIS. 3.3 ISSUE OF UNITS AND PAYMENT THEREON (a) If the Acquisition Time occurs by the Deadline, the Units shall be and shall be deemed to be issued to the Receiptholder in accordance with the right of such holder as described in Section 2.2(a) hereof (which right shall be and shall be deemed to be exercised upon the occurrence of the Acquisition Time) and such Units shall be deemed to be issued pursuant to the Trust Indenture at the Issue Time, notwithstanding that a certificate or a Book-Entry Only System customer confirmation therefor may not yet have been issued or entered, as the case may be, and the persons to whom such Units are to be issued in accordance with the provisions of this Agreement shall be deemed to have become the holders of record of such Units at the Issue Time. (b) If the Acquisition Time occurs by the Deadline, the Receiptholder of record at such time shall be entitled from and after the Issue Time, but shall receive (subject to Section 3.1) no earlier than on the second Business Day following the Acquisition Date, an amount equal to such holder's Acquisition Payment, if any, less applicable withholding taxes, if any, provided that to the extent that this amount, if any, represents amounts in respect of cash distributions for which record dates have occurred but which have not yet been paid, such amount shall not be payable to holders, unless the Trust otherwise elects, until the date such cash distributions are paid to Unitholders; and provided further any Earned Interest shall be paid to the Trust unless Acquisition Payments are required to be paid to each holder, in which case such Acquisition Payments shall be satisfied out of the Earned Interest on the Escrowed Funds. If the Escrowed Funds and Earned Interest are not sufficient to meet the payments required by this Section 3.3(b), the Escrow Agent shall only make payments under this section to the extent monies have been deposited with it pursuant to Section 3.6. Subject to sufficient funds being available to it, the Escrow Agent agrees to cause any amounts to be paid to holders of Subscription Receipts pursuant to this Section 3.3 to be paid on the second Business Day following the Acquisition Date or the date cash distributions are paid to Unitholders, as applicable. (c) Upon the issuance or deemed issuance of the Units pursuant to the Subscription Receipts, the Trust, subject to the provisions of the Trust Indenture, shall direct CDS to cause to be entered and issued, as the case may be, to the person or persons in whose name or names such Units have been issued, a Book-Entry Only System customer confirmation, together with a cheque or cheques or wire transfer for the amounts specified in Section 3.3(b). (d) Effective immediately after the Units have been issued as contemplated in Section 3.3(a) and cheque(s) or wire transfer(s) for the amount specified in Section 3.3(b) have been issued and mailed or delivered (and provided such cheque(s) have been honoured for payment, if presented for payment within six months of the date hereof), the Subscription Receipts relating thereto shall be void and of no value or effect. For greater certainty, any Escrowed Funds, interest or other monies held by the Escrow Agent pursuant hereto after the cheque or cheques or wire transfers for the amount specified in Section 3.3(b) have been mailed or delivered, as the case may be, shall be delivered to the Trust as soon as reasonably practicable thereafter. 3.4 PAYMENT ON TERMINATION (a) If the Acquisition is terminated, the Trust advises the Underwriters or announces to the public that it does not intend to proceed with the Acquisition or the Acquisition Time does not occur, in 14 any such case, by the Deadline, the Trust shall forthwith notify the Escrow Agent thereof and shall issue a press release setting forth the Termination Date. (b) If the Acquisition is terminated, the Trust advises the Underwriters or announces to the public that it does not intend to proceed with the Acquisition or the Acquisition Time does not occur, in any such case, by the Deadline, the subscription evidenced by each Subscription Receipt shall be automatically terminated and cancelled and each Receiptholder shall be entitled from and after the Termination Payment Time, but shall receive no earlier than on the second Business Day following the Termination Date, a payment in the aggregate amount of (i) the Subscription Price in respect of each of such holder's Subscription Receipts; and (ii) such holder's PRO RATA share of the Earned Interest less applicable withholding taxes, if any. The amount paid to each Receiptholder under (i) shall be satisfied by the Escrowed Funds and the amount in (ii), if any, shall be satisfied by the Earned Interest. If the Escrowed Funds are not satisfactory to meet the payment required by Section 3.4(b), the Escrow Agent shall only make payments under this section to the extent monies have been deposited with it pursuant to Section 3.6. The Escrow Agent agrees to cause any amounts to be paid to the holders of Subscription Receipts pursuant to this Section 3.4 on the second Business Day following the Termination Date. (c) If the Acquisition Time does not occur by the Deadline, registers for the Subscription Receipts shall be closed at the close of business on the Termination Date. (d) The obligation to make the payment of the amount specified in Section 3.4(b) shall be satisfied by mailing or delivering payment by cheque or wire transfer to the registered holder of the Subscription Receipt at its registered address. (e) Upon the mailing or delivery of any cheque or wire transfer as provided in Section 3.4(d) (and provided such cheque has been honoured for payment, if presented for payment within six months of the date thereof) all rights evidenced by the Subscription Receipts relating thereto shall be satisfied and such Subscription Receipts shall be void and of no value or effect. For greater certainty, any Escrowed Funds, interest or other monies held by the Escrow Agent pursuant hereto after the cheque or wire transfer for the amount specified in Section 3.4(d) have been mailed or delivered, as the case may be, shall be delivered to the Trust as soon as reasonably practicable thereafter. 3.5 CANCELLATION OF SURRENDERED SUBSCRIPTION RECEIPT CERTIFICATES All Subscription Receipt Certificates surrendered to the Escrow Agent pursuant to Sections 2.10, 2.11 and 5.1 shall be returned to or received by the Escrow Agent for cancellation and, if required by the Trust, the Escrow Agent shall furnish the Trust with a cancellation certificate identifying the Subscription Receipt Certificates so cancelled and the number of Subscription Receipts evidenced thereby. 3.6 ADDITIONAL PAYMENTS BY THE TRUST The Trust shall, no later than one (1) Business Day before the date upon which the Acquisition Payment is required to be paid pursuant to Article 3, pay to the Escrow Agent such amount, if any, as will be sufficient to allow the Escrow Agent to pay in full the Acquisition Payment as is required under the circumstances. 15 3.7 PAYMENT OF UNDERWRITING FEE Upon the release of the Released Amount pursuant to Section 3.2(a), the Escrow Agent shall concurrently deliver a certified cheque or bank draft or complete a wire transfer payable to Scotia Capital Inc. on behalf of the Underwriters in the amount of $1,645,000. ARTICLE 4 INVESTMENT OF PROCEEDS AND PAYMENT OF INTEREST 4.1 INVESTMENT OF PROCEEDS Pending disbursement of the Escrowed Funds, the Escrow Agent shall hold, invest and reinvest the Proceeds on behalf of the Receiptholders in short-term obligations of, or guaranteed by, the Government of Canada, corporate commercial paper which is rated R1 (high), investment certificates of a Canadian bank and other approved investments as directed in writing by the Trust. If at any time the Proceeds include cash that is not invested and the Trust has not provided directions to the Escrow Agent to invest such cash, the Escrow Agent shall deposit all such uninvested cash in an account, a term deposit or guaranteed investment certificates of the Escrow Agent or a Canadian bank, having either no fixed term or no irrevocable term and which pays interest on the daily balance. 4.2 SEGREGATION OF PROCEEDS The Escrowed Funds received by the Escrow Agent and any securities or other instruments received by the Escrow Agent upon the investment or reinvestment of such Escrowed Funds, shall be received as agent for, and shall be segregated and kept apart by the Escrow Agent as agent for, the Receiptholders and the Underwriters.

ARTICLE 7 MEETINGS OF RECEIPTHOLDERS 7.1 RIGHT TO CONVENE MEETINGS The Escrow Agent may at any time and from time to time, and shall on receipt of a written request of the Trust or of a Receiptholders' Request and upon being indemnified to its reasonable satisfaction by the Trust or by the Receiptholders signing such Receiptholders' Request against the cost which may be incurred in connection with the calling and holding of such meeting, convene a meeting of the Receiptholders.

Any business may be brought before or dealt with at an adjourned meeting that might have been dealt with at the original meeting in accordance with the notice calling the same. No business shall be transacted at any meeting unless a quorum is present at the commencement of business. At the adjourned meeting the Receiptholders present in person or by proxy shall form a quorum and may transact the business for which the meeting was originally convened notwithstanding that they may not hold at least 25% of the then outstanding Subscription Receipts. 7.5 POWER TO ADJOURN The chairman of any meeting at which a quorum of the Receiptholders is present may, with the consent of the meeting, adjourn any such meeting and no notice of such adjournment need be given except such notice, if any, as the meeting may prescribe. 7.6 SHOW OF HANDS Every question submitted to a meeting shall be decided in the first place by a majority of the votes given on a show of hands except that votes on an extraordinary resolution shall be given in the manner hereinafter provided. At any such meeting, unless a poll is duly demanded as herein provided, a declaration by the chairman that a resolution has been carried or carried unanimously or by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact. 7.7 POLL AND VOTING On every extraordinary resolution, and on any other question submitted to a meeting and after a vote by show of hands when demanded by the chairman or by one or more of the Receiptholders acting in person or by proxy and holding at least 5% of the then outstanding Subscription Receipts, a poll shall be taken in such manner as the chairman shall direct. Questions other than those required to be determined by extraordinary resolution shall be decided by a majority of the votes cast on the poll.

On a poll, each Receiptholder present in person or represented by a proxy duly appointed by instrument in writing 20 shall be entitled to one vote in respect of each Unit he is entitled to receive pursuant to the Subscription Receipt(s) then held or represented by him. A proxy need not be a Receiptholder. In the case of joint holders, any of them present in person or by proxy at the meeting may vote in the absence of the other or others; but in case more than one of them shall be present in person or by proxy, they shall vote together in respect of Subscription Receipts of which they are joint registered holders. The chairman of any meeting shall be entitled, both on a show of hands and on a poll, to vote in respect of the Subscription Receipts, if any, held or represented by him. 7.8 REGULATIONS The Escrow Agent, or the Trust with the approval of the Escrow Agent, may from time to time make and from time to time vary such regulations as it shall think fit for: (a) the setting of the record date for a meeting of holders of Subscription Receipts for the purpose of determining Receiptholders entitled to receive notice of and vote at such meeting; (b) the issue of voting certificates by any bank, trust company or other depositary satisfactory to the Escrow Agent stating that the Subscription Receipt Certificates specified therein have been deposited with it by a named person and will remain on deposit until after the meeting, which voting certificate shall entitle the persons named therein to be present and vote at any such meeting and at any adjournment thereof or to appoint a proxy or proxies to represent them and vote for them at any such meeting and at any adjournment thereof in the same manner and with the same effect as though the persons so named in such voting certificates were the actual holders of the Subscription Receipt Certificates specified therein; (c) the deposit of voting certificates and instruments appointing proxies at such place and time as the Escrow Agent, the Trust or the Receiptholders, convening the meeting, as the case may be, may in the notice convening the meeting direct; (d) the deposit of voting certificates and instruments appointing proxies at some approved place or places other than the place at which the meeting is to be held and enabling particulars of such instruments appointing proxies to be mailed or telecopied before the meeting to the Trust or to the Escrow Agent at the place where the same is to be held and for the voting of proxies so deposited as though the instruments themselves were produced at the meeting; (e) the form of the instrument of proxy; and (f) generally for the calling of meetings of Receiptholders and the conduct of business thereat. Any regulations so made shall be binding and effective and the votes given in accordance therewith shall be valid and shall be counted. Save as such regulations may provide, the only persons who shall be recognized at any meeting as a Receiptholder, or be entitled to vote or be present at the meeting in respect thereof (subject to Section 7.9), shall be Receiptholders or their counsel, or proxies of Receiptholders. 7.9 TRUST AND ESCROW AGENT MAY BE REPRESENTED The Trust, AOG and the Escrow Agent, by their respective authorized agents, and the counsel for the Trust and for the Escrow Agent may attend any meeting of the Receiptholders, but shall have no vote as such unless in their capacity as Receiptholder or a proxy holder. 21 7.10 POWERS EXERCISABLE BY EXTRAORDINARY RESOLUTION In addition to all other powers conferred upon them by any other provisions of this Agreement or by law, the Receiptholders at a meeting shall, subject to the provisions of Section 7.11, have the power, subject to all applicable regulatory and exchange approvals, exercisable from time to time by extraordinary resolution: (a) to agree to any modification, abrogation, alteration, compromise or arrangement of the rights of Receiptholders or the Escrow Agent against the Trust or against its undertaking, property and assets or any part thereof whether such rights arise under this Agreement or the Subscription Receipt Certificates or otherwise; (b) to amend, alter or repeal any extraordinary resolution previously passed or sanctioned by the Receiptholders; (c) to direct or to authorize the Escrow Agent to enforce any of the covenants on the part of the Trust contained in this Agreement or the Subscription Receipt Certificates or to enforce any of the rights of the Receiptholders in any manner specified in such extraordinary resolution or to refrain from enforcing any such covenant or right; (d) to waive, and to direct the Escrow Agent to waive, any default on the part of the Trust in complying with any provisions of this Agreement or the Subscription Receipt Certificates either unconditionally or upon any conditions specified in such extraordinary resolution; (e) to restrain any Receiptholder from taking or instituting any suit, action or proceeding against the Trust for the enforcement of any of the covenants on the part of the Trust in this Agreement or the Subscription Receipt Certificates or to enforce any of the rights of the Receiptholders; (f) to direct any Receiptholder who, as such, has brought any suit, action or proceeding to stay or to discontinue or otherwise to deal with the same upon payment of the costs, charges and expenses reasonably and properly incurred by such Receiptholder in connection therewith; (g) to assent to any modification of, change in or omission from the provisions contained in the Subscription Receipt Certificates and this Agreement or any ancillary or supplemental instrument which may be agreed to by the Trust, and to authorize the Escrow Agent to concur in and execute any ancillary or supplemental agreement embodying the change or omission; (h) with the consent of the Trust (such consent not to be unreasonably withheld), to remove the Escrow Agent or its successor in office and to appoint a new Escrow Agent to take the place of the Escrow Agent so removed; (i) to assent to any compromise or arrangement with any creditor or creditors or any class or classes of creditors, whether secured or otherwise, and with holders of any Units or other securities of the Trust; and (j) to assent to any modification of the Trust Indenture in circumstances where, had the Units then been outstanding, an extraordinary resolution of the holders of Units would have been required. 22 7.11 MEANING OF EXTRAORDINARY RESOLUTION (a) The expression "extraordinary resolution" when used in this Agreement means, subject as hereinafter provided in this Section 7.11 and in Section 7.14, a resolution proposed at a meeting of Receiptholders duly convened for that purpose and held in accordance with the provisions of this Article 7 at which there are present in person or by proxy at least two (2) Receiptholders holding more than 25% of the then outstanding Subscription Receipts and passed by the affirmative votes of Receiptholders holding not less than 66 2/3% of the then outstanding Subscription Receipts represented at the meeting and voted on the poll upon such resolution.

ARTICLE 9 CONCERNING THE ESCROW AGENT 9.1 RIGHTS AND DUTIES OF ESCROW AGENT (a) In the exercise of the rights and duties prescribed or conferred by the terms of this Agreement, the Escrow Agent shall exercise that degree of care, diligence and skill that a reasonably prudent escrow agent would exercise in comparable circumstances. No provision of this Agreement shall be construed to relieve the Escrow Agent from liability for its own negligent action, its own negligent failure to act, or its own wilful misconduct or bad faith. (b) The obligation of the Escrow Agent to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Escrow Agent or the Receiptholders hereunder shall be conditional upon the Receiptholders furnishing, when required by notice by the Escrow Agent, sufficient funds to commence or to continue such act, action or proceeding and an indemnity reasonably satisfactory to the Escrow Agent to protect and to hold harmless the Escrow Agent against the costs, charges and expenses and liabilities to be incurred thereby and any loss and damage it may suffer by reason thereof. None of the provisions contained in this Agreement shall require the Escrow Agent to expend or to risk its own funds or otherwise to incur financial liability in the performance of any of its duties or in the exercise of any of its rights or powers unless indemnified as aforesaid. 25 (c) The Escrow Agent may, before commencing or at any time during the continuance of any such act, action or proceeding, require the Receiptholders at whose instance it is acting to deposit with the Escrow Agent the Subscription Receipts held by them, for which Subscription Receipts the Escrow Agent shall issue receipts. (d) Every provision of this Agreement that by its terms relieves the Escrow Agent of liability or entitles it to rely upon any evidence submitted to it is subject to the provisions of this Section 9.1 and of Section 9.2. (e) The Escrow Agent shall have no duties except those expressly set forth herein, and it shall not be bound by any notice of a claim or demand with respect to, or any waiver, modification, amendment, termination or rescission of, this Agreement, unless received by it in writing and signed by the other parties hereto and, if its duties herein are affected, unless it shall have given its prior written consent thereto. (f) The Escrow Agent shall not be responsible for ensuring that the Proceeds are used in the manner contemplated by the Prospectus. (g) The Escrow Agent shall retain the right not to act and shall not be held liable for refusing to act unless it has received clear and reasonable documentation which complies with the terms of this Agreement, which documentation does not require the exercise of any discretion or independent judgment. (h) The Escrow Agent shall incur no liability whatsoever with respect to the delivery or non-delivery of any certificates whether delivery by hand, mail or any other means. (i) The Escrow Agent shall not be responsible or liable in any manner whatsoever for the deficiency, correctness, genuineness or validity of any securities deposited with it. 9.2 EVIDENCE, EXPERTS AND ADVISERS (a) In addition to the reports, certificates, opinions and other evidence required by this Agreement, the Trust shall furnish to the Escrow Agent such additional evidence of compliance with any provision hereof, and in such form, as the Escrow Agent may reasonably require by written notice to the Trust. (b) In the exercise of its rights and duties hereunder, the Escrow Agent may, if it is acting in good faith, rely as to the truth of the statements and the accuracy of the opinions expressed in statutory declarations, opinions, reports, written requests, consents, or orders of the Trust, certificates of the Trust or other evidence furnished to the Escrow Agent pursuant to any provision hereof or pursuant to a request of the Escrow Agent. (c) Whenever it is provided in this Agreement that the Trust shall deposit with the Escrow Agent resolutions, certificates, reports, opinions, requests, orders or other documents, it is intended that the trust, accuracy and good faith on the effective date thereof and the facts and opinions stated in all such documents so deposited shall, in each and every such case, be conditions precedent to the right of the Trust to have the Escrow Agent take the action to be based thereon. (d) Proof of the execution of an instrument in writing, including a Receiptholders' Request, by any Receiptholder may be made by the certificate of a notary public, or other officer with similar powers, that the person signing such instrument acknowledged to the officer the 26 execution thereof, or by an affidavit of a witness to such execution or in any other manner which the Escrow Agent may consider adequate. (e) The Escrow Agent may employ or retain such Counsel, accountants, appraisers or other experts or advisers as it may reasonably require for the purpose of discharging its duties hereunder and may pay reasonable remuneration for all services so performed by any of them, without taxation of costs of any Counsel, and shall not be responsible for any misconduct or negligence on the part of any such experts or advisers who have been appointed with due care by the Escrow Agent. 9.3 DOCUMENTS, MONIES, ETC. HELD BY ESCROW AGENT Any securities, documents of title or other instruments that may at any time be held by the Escrow Agent pursuant to this Agreement may be placed in the deposit vaults of the Escrow Agent or of any Canadian bank or deposited for safekeeping with any such bank. If the Escrow Agent has not received a direction under Section 4.1, any monies so held pending the application or withdrawal thereof under any provisions of this Agreement may be deposited in the name of the Escrow Agent in any Canadian bank, or in the deposit department of the Escrow Agent or any other loan or trust company authorized to accept deposits under the laws of Canada or a province thereof, at the rate of interest (if any) then current on similar deposits. 9.4 ACTIONS BY ESCROW AGENT TO PROTECT INTEREST The Escrow Agent shall have power to institute and to maintain such actions and proceedings as it may consider necessary or expedient to preserve, protect or enforce its interests and the interests of the Receiptholders. 9.5 ESCROW AGENT NOT REQUIRED TO GIVE SECURITY The Escrow Agent shall not be required to give any bond or security in respect of the execution of this Agreement or otherwise in respect of the premises. 9.6 PROTECTION OF ESCROW AGENT By way of supplement to the provisions of any law for the time being relating to trustees it is expressly declared and agreed as follows: (a) the Escrow Agent shall not be liable for or by reason of any statements of fact or recitals in this Agreement or in the Subscription Receipt Certificates (except the representation contained in Section 9.8 or in the certificate of the Escrow Agent on the Subscription Receipt Certificates) or be required to verify the same, but all such statements or recitals are and shall be deemed to be made by the Trust; (b) nothing herein contained shall impose any obligation on the Escrow Agent to see to or to require evidence of the registration or filing (or renewal thereof) of this Agreement or any instrument ancillary or supplemental hereto; (c) the Escrow Agent shall not be bound to give notice to any person or persons of the execution hereof; and (d) the Escrow Agent shall not incur any liability or responsibility whatever or be in any way responsible for the consequence of any breach on the part of the Trust of any of the covenants herein contained or of any acts of any officers, employees, agents or servants of the Trust or AOG. 27 9.7 REPLACEMENT OF ESCROW AGENT; SUCCESSOR BY MERGER (a) The Escrow Agent may resign its appointment and be discharged from all other duties and liabilities hereunder, subject to this Section 9.7, by giving to the Trust not less than thirty (30) days prior notice in writing or such shorter prior notice as the Trust may accept as sufficient.

In the event of the Escrow Agent resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Lead Underwriter, on behalf of the Underwriters, shall forthwith appoint a new escrow agent unless a new escrow agent has already been appointed by the Receiptholders; failing such appointment by the Lead Underwriter, on behalf of the Underwriters, the retiring Escrow Agent or any Receiptholder may apply to a justice of the Court of Queen's Bench (Alberta) on such notice as such justice may direct, for the appointment of a new escrow agent; but any new escrow agent so appointed by the Lead Underwriter, on behalf of the Underwriters, or by the Court shall be subject to removal as aforesaid by the Receiptholders. Any new escrow agent appointed under any provision of this Section 9.7 shall be a corporation authorized to carry on the business of a trust company in the Provinces of Alberta and Ontario and, if required by the applicable legislation for any other provinces, in such other provinces. On any such appointment, the new escrow agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Escrow Agent hereunder. At the request of the Trust or the new Escrow Agent, the retiring Escrow Agent, upon payment of the amounts, if any, due to it pursuant to Section 5.3, shall duly assign, transfer and deliver to the new Escrow Agent all property and money held and all records kept by the retiring Escrow Agent hereunder or in connection herewith. (b) Upon the appointment of a successor escrow agent, the Trust shall promptly notify the Receiptholders thereof in the manner provided for in Article 10. (c) Any corporation into or with which the Escrow Agent may be merged or consolidated or amalgamated, or any corporation resulting therefrom to which the Escrow Agent shall be a party, or any corporation succeeding to the corporate trust business of the Escrow Agent shall be the successor to the Escrow Agent hereunder without any further act on its part or any of the parties hereto, provided that such corporation would be eligible for appointment as a successor escrow agent under Subsection 9.7(a). (d) Any Subscription Receipt Certificates certified but not delivered by a predecessor escrow agent may be delivered by the successor escrow agent in the name of the predecessor or successor escrow agent. 9.8 CONFLICT OF INTEREST (a) The Escrow Agent represents to the Trust and the Lead Underwriter, on behalf of the Underwriters, that at the time of execution and delivery hereof no material conflict of interest exists between its role as a escrow agent hereunder and its role in any other capacity and agrees that in the event of a material conflict of interest arising hereafter it will, within thirty (30) days after ascertaining that it has such material conflict of interest, either eliminate the same or assign its appointment as escrow agent hereunder to a successor escrow agent approved by the Trust and meeting the requirements set forth in Subsection 9.7(a).
