(b) Subscription Receipt Certificates may be surrendered for exchange only at the Designated Office during regular business hours of the Subscription Receipt Agent. 2.12 CHARGES FOR EXCHANGE Except as otherwise herein provided, the Subscription Receipt 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 Subscription Receipt 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), 2.14 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 the Designated Office 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 the Designated Office and upon compliance with Sections 2.14 and 2.15, the Trust shall issue and thereupon the Subscription Receipt 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 Subscription Receipt Agent of a reasonable sum for each new Subscription Receipt Certificate issued upon such transfer, and reimbursement of the Subscription Receipt 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 Subscription Receipt Agent may prescribe, and all such transfers shall be duly noted in such register by the Subscription Receipt Agent. (b) The Trust and the Subscription Receipt 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 Subscription Receipt Agent shall be affected by any notice to the contrary. (c) The transfer register in respect of Subscription Receipts shall be closed at 5:00 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 Subscription Receipt Agent shall promptly advise the Trust of any requested transfer of Subscription Receipts. The Trust shall be entitled, and may direct the Subscription Receipt 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 Trust Units and the payment of the Earned Interest and applicable Acquisition Payment, each less applicable withholding taxes, as provided in Section 3.3, or the payment of the Subscription Price and the Earned Interest, each less applicable withholding taxes, as provided in Section 3.5, all in accordance with the terms and conditions herein contained, shall discharge all responsibilities of the Trust and the Subscription Receipt Agent with respect to such Subscription Receipts and neither the Trust nor the Subscription Receipt Agent shall be bound to inquire into the title of a Receiptholder or a transferee of Subscription Receipts who surrenders a Subscription Receipt Certificate. GLOBAL SUBSCRIPTION RECEIPT (a) Unless the Book-Entry Only System is terminated, Subscription Receipt Certificates will only be issued in the form of one or more Global Subscription Receipt certificates, which will be registered in the name of and deposited with CDS (or its nominee). (b) Unless the Book-Entry Only System is terminated, 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 Subscription Receipt 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 and the Subscription Receipt Agent 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 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 Subscription Receipt 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 Subscription Receipt Agent will give such notices and communications to CDS. (e) If CDS resigns or is removed from its responsibility as depository and the Subscription Receipt Agent is unable or does not wish to locate a qualified successor, CDS shall surrender the Global Subscription Receipts to the Subscription Receipt 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 Subscription Receipt 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. LIMITATION ON NON-RESIDENT OWNERSHIP At no time may more than one-half of the outstanding Trust Units be held by Non-Residents. The Trust may direct the Subscription Receipt Agent to require declarations as to the jurisdictions in which beneficial owners of Subscription Receipts are resident, which will be delivered to the Subscription Receipt Agent. If the Subscription Receipt Agent becomes aware, as a result of such declarations as to beneficial ownership or otherwise, that the beneficial owners of 49% of the Trust Units then outstanding (on a fully-diluted basis assuming Trust Units are issued in exchange for the Subscription Receipts) are, or may be, Non-Residents or that such a situation is imminent, the Trust may direct the Subscription Receipt Agent to make a public announcement thereof and, following notification to the Trust of such announcement, the Trust may direct the Subscription Receipt Agent to not register a transfer of Subscription Receipts to a person unless the person provides a declaration in form and content satisfactory to the Trust, as provided to the Subscription Receipt Agent that the person is not a Non-Resident. If, notwithstanding the foregoing, the Subscription Receipt Agent in carrying out the directions of the Trust determines that a majority of the holders of Trust Units (on a fully-diluted basis assuming Trust Units are issued in exchange for the Subscription Receipts) are held by non-residents, the Trust may direct the Subscription Receipt Agent to send a notice to Non-Resident Receiptholders, chosen in inverse order to the order of acquisition or registration or in such other manner as the Trust may direct, requiring them to sell their Subscription Receipts or a portion thereof within a specified period of not less than 60 days. If the Non-Resident Receiptholders receiving such notice have not sold the specified number of Subscription Receipts or provided the Subscription Receipt Agent, as confirmed by the Trust, with satisfactory evidence that they are not Non-Residents within such period, the Trust may direct the Subscription Receipt Agent, on behalf of such Non-Resident Receiptholders, to sell such Subscription Receipts and, in the interim, to suspend the voting and interest rights attached to such Subscription Receipts. Upon such sale, the affected Non-Resident Receiptholders shall cease to be holders of Subscription Receipts and their rights shall be limited to receiving the net proceeds of sale upon surrender of the applicable Subscription Receipts. The Subscription Receipt Agent is, upon direction of the Trust, empowered to take all steps necessary, including cancelling Subscription Receipts and amending the register, as are required to effect any such sale. For greater certainty the Subscription Receipt Agent has no obligation to actively monitor holdings of Non-Residents and is only required to follow the express written directions of the Trust in accordance with this Agreement. 2.16 LISTING OF SUBSCRIPTION RECEIPTS The Trust confirms that the Subscription Receipts will be listed 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 exercisable 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 Trust 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. ARTICLE 3 SATISFACTION OF ISSUANCE RIGHT OR TERMINATION PAYMENT RIGHT 3.1 NOTICE OF THE ACQUISITION If, prior to the Deadline, the Trust is in a position to close the Acquisition, it: (a) shall cause to be delivered to the Subscription Receipt Agent a notice executed by the Trust and by the Lead Underwriter, on behalf of the Underwriters, containing the following: (i) a certification that all conditions precedent to the completion of the Acquisition have been satisfied or waived (other than the delivery of funds); (ii) the specifics relating to the nature of a waiver, if any, of a material closing condition for the benefit of Harvest Breeze Trust No. 1 and Harvest Breeze Trust No. 2 contained in the Purchase Agreement; and (iii) that Harvest Breeze Trust No. 1 and Harvest Breeze Trust No. 2 are in a position to complete the Acquisition (or which notice shall contain any such other terms as Harvest Breeze Trust No. 1 and Harvest Breeze Trust No. 2 and the Subscription Receipt Agent, with the consent of the Lead Underwriter, may agree upon); (b) shall direct the Subscription Receipt Agent in writing to issue and deliver the Trust Units issuable pursuant to the Subscription Receipts and make the payments as provided for herein; and (c) shall, after the Acquisition Time, issue a press release setting out the Acquisition Date and that the Trust Units will be issued effective as at the Issue Time. 3.2 RELEASE OF FUNDS ON THE ACQUISITION DATE Upon the receipt of the joint notice set forth in Section 3.1, the Trust shall be entitled to receive from the Subscription Receipt Agent the Proceeds, less: (i) the amount, if any, required to make the payments set forth in Sections 3.3(b)(i) and (ii) (the "Released Amount"). The Subscription Receipt Agent shall deliver the Released Amount to the Trust, or to such other party as the Trust directs in writing, as soon as reasonably practicable after the delivery of the notice referred to in Section 3.1 and in any event not later than the Issue Time. 3.3 ISSUE OF TRUST UNITS AND PAYMENT THEREON (a) If the Acquisition Time occurs by the Deadline, the Trust 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 Trust 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 Trust 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 Trust Units at the Issue Time. (b) If the Acquisition Time occurs by the Deadline, the holder of a Subscription Receipt (or a transferee thereof if all applicable transfer requirements, other than registration, have been satisfied) 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, a certificate representing the applicable number of Trust Units issuable pursuant to such holder's Subscription Receipts and a cheque in an amount of (i) such holder's PRO RATA share of any Earned Interest less applicable withholding taxes and (ii) the difference, if any, between the holder's Acquisition Payment and such holder's PRO RATA share of the Earned Interest, less applicable withholding taxes; provided that to the extent that the amount in (ii), 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 that if the holder is not entitled to an Acquisition Payment such holder's PRO RATA share of any Earned Interest shall be paid to the Trust in accordance with Section 3.2. The amount paid to each holder under (i), if any, shall be satisfied by the Earned Interest and the amount in (ii), if any, shall be satisfied by the Escrowed Funds as provided in Section 3.2. If the Escrowed Funds and Earned Interest are not sufficient to meet the payments required by this Section 3.3(b), the Subscription Receipt Agent shall only make payments under this section to the extent monies have been deposited with it pursuant to Section 3.7. (c) Upon the issuance or deemed issuance of the Trust 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 Trust 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 Trust Units have been issued as contemplated in Section 3.3(a) and the certificates representing such Trust Units have been entered and issued, as the case may be, as provided in Section 3.3(c) and the cheque or cheques for the amount specified in Section 3.3(b) have been issued and mailed or delivered (and provided such cheque or cheques 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 Subscription Receipt Agent pursuant hereto after the cheque or cheques 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 FRACTIONS Notwithstanding anything herein contained, the Trust shall not be required, upon the exercise or deemed exercise of the Subscription Receipt to issue fractions of Trust Units. In lieu of fractional Trust Units, there shall be paid to the holder, within 10 Business Days after surrender of the Subscription Certificate, an amount in lawful money of Canada equal to the then current market value of such fractional interest computed on the basis of the Current Market Price on the Acquisition Date. 3.5 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 any such case, by the Deadline, the Trust shall forthwith notify the Subscription Receipt 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 (or a transferee thereof if all applicable transfer requirements, other than registration, have been satisfied) 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 cheque 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; by surrendering, at any time after the Termination Date, to the Subscription Receipt Agent at the Designated Office the applicable Subscription Receipt Certificate. 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 3.5(b)(ii), the Subscription Receipt Agent shall only make payments under this section to the extent monies have been deposited with it pursuant to Section 3.7. (c) If the Acquisition Time does not occur by the Deadline, registers shall be closed at the close of business on the Termination Date. (d) A Surrender Form submitted upon surrender of a Subscription Receipt Certificate as contemplated in Section 3.5(b) shall be signed by the Receiptholder (or a transferee thereof if all applicable transfer requirements, other than registration, have been satisfied) and shall specify the name and address of the person to whom the amount specified in Section 3.5(b) shall be paid. (e) The obligation to make the payment of the amount specified in Section 3.5(b) shall be satisfied by: (i) mailing payment by cheque payable at par in Calgary, Alberta and to the payee specified in the Surrender Form and at the address specified for such payee in the Surrender Form; or (ii) if so requested by the person surrendering the relevant Subscription Receipt Certificate, actual delivery of a cheque payable at par in Calgary, Alberta to the payee specified in the Surrender Form at the Designated Office where the Subscription Receipt was surrendered. The mailing or delivering of such cheque shall occur as soon as practicable following the surrender of the Subscription Receipt Certificate. (f) If any Subscription Receipts Certificates have not been surrendered as contemplated in Section 3.5(b) by December 30, 2005, or any earlier time after the Termination Date at the election of the Trust, the Subscription Receipt Agent shall mail the cheques in payment of the amount specified in Section 3.5(b) to the holders of such Subscription Receipts at their last addresses of record. (g) Upon the mailing or delivery of any cheque as provided in Sections 3.5(d) and (e) (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 Subscription Receipt Agent pursuant hereto after the cheque or cheques for the amount specified in Sections 3.5(d) and (e) have been mailed or delivered, as the case may be, shall be delivered to the Trust as soon as reasonably practicable thereafter. 3.6 CANCELLATION OF SURRENDERED SUBSCRIPTION RECEIPT CERTIFICATES All Subscription Receipt Certificates surrendered to the Subscription Receipt Agent pursuant to Sections 2.10, 2.11, 3.5 and 5.1 shall be returned to or received by the Subscription Receipt Agent for cancellation and, if required by the Trust, the Subscription Receipt Agent shall furnish the Trust with a cancellation certificate identifying the Subscription Receipt Certificates so cancelled and the number of Subscription Receipts evidenced thereby. 3.7 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 Subscription Receipt Agent such amount, if any, as will be sufficient to allow the Subscription Receipt Agent to pay in full the Acquisition Payment as is required under the circumstances. ARTICLE 4 INVESTMENT OF PROCEEDS AND PAYMENT OF INTEREST 4.1 INVESTMENT OF PROCEEDS Pending disbursement of the Escrowed Funds, the Subscription Receipt 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 (middle), investment certificates of a Canadian chartered 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 Subscription Receipt Agent to invest such cash, the Subscription Receipt Agent shall deposit all such uninvested cash in an account, a term deposit or guaranteed investment certificates of the Subscription Receipt Agent or a Canadian chartered 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 Subscription Receipt Agent and any securities or other instruments received by the Subscription Receipt 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 Subscription Receipt Agent as agent for, the Receiptholders and the Underwriters.

ARTICLE 6 ENFORCEMENT 6.1 SUITS BY RECEIPTHOLDERS All or any of the rights conferred upon any Receiptholder by any of the terms of the Subscription Receipt Certificates or of this Agreement, or of both, may be enforced by the Receiptholder by appropriate proceedings but without prejudice to the right which is hereby conferred upon the Subscription Receipt Agent to proceed in its own name to enforce each and all of the provisions contained herein for the benefit of the Receiptholders. 6.2 IMMUNITY OF UNITHOLDERS, ETC.

Such notice shall state the date (which should be a Business Day) and time when, and the place where the meeting, is to be held, shall state briefly the general nature of the business to be transacted thereat and shall contain such information as is reasonably necessary to enable the Receiptholders to make a reasoned decision on the matter, but it shall not be necessary for any such notice to set out the terms of any resolution to be proposed or any of the provisions of this Article 7. 7.3 CHAIRMAN An individual (who need not be a Receiptholder) designated in writing by the Subscription Receipt Agent shall be chairman of the meeting and if no individual is so designated, or if the individual so designated is not present within fifteen (15) minutes from the time fixed for the holding of the meeting, the Receiptholders present in person or by proxy shall choose some individual present to be chairman. 7.4 QUORUM Subject to the provisions of Section 7.11, at any meeting of the Receiptholders a quorum shall consist of not less than two (2) Receiptholders present in person or by proxy and holding 10% of the then outstanding Subscription Receipts.

Any business may be brought before or dealt with at an adjourned meeting which 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 be 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 10% 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 show of hands, every person who is present and entitled to vote, whether as a Receiptholder or as proxy for one or more absent Receiptholders, or both, shall have one vote. On a poll, each Receiptholder present in person or represented by a proxy duly appointed by instrument in writing 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. REGULATIONS The Subscription Receipt Agent, or the Trust with the approval of the Subscription Receipt 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 Subscription Receipt 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 Subscription Receipt 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 Subscription Receipt 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 SUBSCRIPTION RECEIPT AGENT MAY BE REPRESENTED The Trust and the Subscription Receipt Agent, by their respective authorized agents, and the counsel for the Trust and for the Subscription Receipt 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. 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 Subscription Receipt 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 Subscription Receipt 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 Subscription Receipt 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 Subscription Receipt 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 Subscription Receipt Agent or its successor in office and to appoint a new Subscription Receipt Agent to take the place of the Subscription Receipt 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 Trust Units or other securities of the Trust; and (j) to assent to any modification of the Trust Indenture in circumstances where, had the Trust Units then been outstanding, an extraordinary resolution of the holders of Trust Units would have been required. 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 10% 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. (b) If, at any meeting called for the purpose of passing an extraordinary resolution, at least two (2) Receiptholders holding more than 10% of the then outstanding Subscription Receipts are not present in person or by proxy within thirty (30) minutes after the time appointed for the meeting, then the meeting, if convened by Receiptholders or on a Receiptholders' Request, shall be dissolved; but in any other case it shall stand adjourned to such day, being not less than fourteen (14) or more than thirty (30) days later, and to such place and time as may be appointed by the chairman. Not less than seven (7) days prior notice shall be given of the time and place of such adjourned meeting in the manner provided for in Section 10.2. Such notice shall state that at the adjourned meeting the Receiptholders present in person or by proxy shall form a quorum but it shall not be necessary to set forth the purposes for which the meeting was originally called or any other particulars.

ARTICLE 9 CONCERNING THE SUBSCRIPTION RECEIPT AGENT RIGHTS AND DUTIES OF SUBSCRIPTION RECEIPT AGENT (a) In the exercise of the rights and duties prescribed or conferred by the terms of this Agreement, the Subscription Receipt Agent shall exercise that degree of care, diligence and skill that a reasonably prudent Subscription Receipt Agent would exercise in comparable circumstances. No provision of this Agreement shall be construed to relieve the Subscription Receipt Agent from liability for its own negligent action, its own negligent failure to act, or its own negligence, wilful misconduct or bad faith. (b) The obligation of the Subscription Receipt Agent to commence or continue any act, action or proceeding for the purpose of enforcing any rights of the Subscription Receipt Agent or the Receiptholders hereunder shall be conditional upon the Receiptholders furnishing, when required by notice by the Subscription Receipt Agent, sufficient funds to commence or to continue such act, action or proceeding and an indemnity reasonably satisfactory to the Subscription Receipt Agent to protect and to hold harmless the Subscription Receipt 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 Subscription Receipt 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. (c) The Subscription Receipt 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 Subscription Receipt Agent the Subscription Receipts held by them, for which Subscription Receipts the Subscription Receipt Agent shall issue receipts. (d) Every provision of this Agreement that by its terms relieves the Subscription Receipt 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 Subscription Receipt 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 rights or duties herein are affected, unless it shall have given its prior written consent thereto. (f) The Subscription Receipt Agent shall not be responsible for ensuring that the Proceeds are used in the manner contemplated by the Prospectus. (g) The Subscription Receipt 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 Subscription Receipt 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 Subscription Receipt Agent shall not be responsible or liable in any manner whatsoever for the deficiency, correctness, genuineness or validity of any securities deposited with it. 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 Subscription Receipt Agent such additional evidence of compliance with any provision hereof, and in such form, as the Subscription Receipt Agent may reasonably require by written notice to the Trust. (b) In the exercise of its rights and duties hereunder, the Subscription Receipt 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 Subscription Receipt Agent pursuant to any provision hereof or pursuant to a request of the Subscription Receipt Agent. (c) Whenever it is provided in this Agreement that the Trust shall deposit with the Subscription Receipt Agent resolutions, certificates, reports, opinions, requests, orders or other documents, it is intended that the truth, 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 Subscription Receipt 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 execution thereof, or by an affidavit of a witness to such execution or in any other manner which the Subscription Receipt Agent may consider adequate. (e) The Subscription Receipt 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 Subscription Receipt Agent. 9.3 DOCUMENTS, MONIES, ETC. HELD BY SUBSCRIPTION RECEIPT AGENT Any securities, documents of title or other instruments that may at any time be held by the Subscription Receipt Agent pursuant to this Agreement may be placed in the deposit vaults of the Subscription Receipt Agent or of any Canadian chartered bank or deposited for safekeeping with any such bank.

At the request of the Trust or the new subscription receipt agent, the retiring subscription receipt 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 subscription receipt agent all property and money held and all records kept by the retiring subscription receipt agent hereunder or in connection herewith.

(c) Any corporation into or with which the Subscription Receipt Agent may be merged or consolidated or amalgamated, or any corporation resulting therefrom to which the Subscription Receipt Agent shall be a party, or any corporation succeeding to the corporate trust business of the Subscription Receipt Agent shall be the successor to the Subscription Receipt 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 subscription receipt agent under Subsection 9.7(a). (d) Any Subscription Receipt Certificates certified but not delivered by a predecessor subscription receipt agent may be delivered by the successor subscription receipt agent in the name of the predecessor or successor subscription receipt agent. 9.8 CONFLICT OF INTEREST (a) The Subscription Receipt 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 subscription receipt 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 subscription receipt agent hereunder to a successor subscription receipt agent approved by the Trust and meeting the requirements set forth in Subsection 9.7(a).
