(a) On each Common Share Dividend Payment Date in respect of which a Common Share Dividend Record Date occurs from the date hereof to but excluding the Acquisition Closing Date, or to and including the Termination Date, as applicable, the Subscription Receipt Agent shall pay to Receiptholders of record on the Common Share Dividend Record Date relating to such Common Share Dividend Payment Date, if any, an amount in cash in respect of each of their Subscription Receipts that is equal to the Common Share Dividend payable per Common Share on such Common Share Dividend Payment Date (or, in the event that the Termination Time occurs, within the timeframe specified by Section 3.3(a)(ii)).

(b) If the Termination Date occurs after a Common Share Dividend Declaration Date but before the Common Share Dividend Record Date for the Common Share Dividend declared on such Common Share Dividend Declaration Date, the Subscription Receipt Agent shall pay to Receiptholders of record on the Termination Date, an amount in respect of each of their Subscription Receipts that is equal to the Common Share Dividend payable per Common Share on such Common Share Dividend Payment Date multiplied by a fraction equal to: (i) the number of days from, and including, the date of the prior Dividend Equivalent Payment (or, if none, the date of this Agreement) to, but excluding, the Termination Date; over (ii) the number of days from, and including, the date of the prior Dividend Equivalent Payment (or, if none, the prior Common Share Dividend Payment Date) to, but excluding, the Common Share Dividend Payment Date in respect of such Common Share Dividend.

(c) Amounts to be paid to Receiptholders by the Subscription Receipt Agent pursuant to Section 2.3(a) and Section 2.3(b) (each such amount, a “Dividend Equivalent Payment”) shall be paid (and shall be deemed to be paid) first pro

(e) The obligation to pay the Dividend Equivalent Payment shall be satisfied by mailing or delivering payment therefor by cheque or wire transfer or, in respect of all payments in excess of $25,000,000 (or such other amount as determined from time to time by the Canadian Payments Association or any successor thereto) by the use of the large value electronic money transfer system operated by the Canadian Payments Association and any successor thereto (“LVTS”), to the Receiptholder at its registered address.

If payment is made by cheque, such cheque shall be forwarded to the Receiptholder at least three Business Days prior to the date on which the payment is to be made. If payment is made by wire transfer or LVTS, it shall be made by noon (Calgary time) on the date on which the payment is to be made.

Upon surrender for registration of transfer of Subscription Receipts at one of the Designated Offices, the Corporation 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 provisions of this Section 2.14(a), Subscription Receipts shall only be transferred upon:

The Subscription Receipt Agent shall withdraw all or any of the Escrowed Funds and Escrowed Underwriters’ Funds that may then be deposited with an Approved Bank if the Subscription Receipt Agent has received notice from the Lead Underwriters or the Corporation that such Approved Bank fails to so qualify at any time, and re-deposit such amount with one or more of such other Approved Banks.

(c) All Escrowed Funds held by the Subscription Receipt Agent pursuant to this Agreement shall be held by the Subscription Receipt Agent solely as agent and bailee on behalf of the Receiptholders, and for certainty shall not form part of the property, estate, assets, undertaking or effects of the Subscription Receipt Agent. The delivery of the Escrowed Funds to the Subscription Receipt Agent shall not give rise to a debtor-creditor or other similar relationship between the Subscription Receipt Agent and the Receiptholders.

(d) The Escrowed Funds held by the Subscription Receipt Agent pursuant to this Agreement are the sole risk of the Receiptholders and the Escrowed Underwriters’ Funds held by the Subscription Receipt Agent pursuant to this Agreement are the sole risk of the Corporation, and, without limiting the generality of the foregoing, the Subscription Receipt Agent shall have no responsibility or liability for any diminution of the Escrowed Funds or the Escrowed Underwriters’ Funds which may result from any deposit made with an Approved Bank pursuant to this Section 4.1, including any losses resulting from a default by the Approved Bank or other credit losses (whether or not resulting from such a default) and any credit or other losses on any deposit liquidated or sold prior to maturity. Each of the Corporation and the Lead Underwriters, on behalf of the Underwriters, acknowledges and agrees that the Subscription Receipt Agent acts prudently in depositing the Escrowed Funds and the Escrowed Underwriters’ Funds at any Approved Bank, and that the Subscription Receipt Agent is not required to make any further inquiries in respect of any such bank.

(i) the Subscription Receipt Agent’s written notice shall describe the circumstances of such non-compliance; and

6.2 Immunity of Shareholders, etc.

The Subscription Receipt Agent and, by the acceptance of the Subscription Receipt Certificates and as part of the consideration for the issue of the Subscription Receipts, the Receiptholders hereby waive and release any right, cause of action or remedy now or hereafter existing in any jurisdiction against any past, present or future shareholder, director, officer, employee or agent of the Corporation or any successor entity for the issue of the Common Shares pursuant to any Subscription Receipt or on any covenant, agreement, representation or warranty by the Corporation contained herein or in the Subscription Receipt Certificate(s).

The Subscription Receipt Agent may at any time and from time to time, and shall on receipt of a written request of the Corporation or of a Receiptholders’ Request and upon being indemnified to its reasonable satisfaction by the Corporation 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. In the event of the Subscription Receipt Agent failing to so convene a meeting within 10 days after receipt of such written request of the Corporation or such Receiptholders’ Request and indemnity given as

7.2 Notice

At least 10 days prior notice of any meeting of Receiptholders shall be given to the Receiptholders in the manner provided for in Section 10.2 and a copy of such notice shall be sent by mail to the Subscription Receipt Agent (unless the meeting has been called by the Subscription Receipt Agent) and to the Corporation (unless the meeting has been called by the Corporation). 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 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 Receiptholders present in person or by proxy and holding more than 25% of the then outstanding Subscription Receipts.

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 more than 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 Receiptholders present in person or by proxy at 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

(a) 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.

(b) 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 Common Share 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 Subscription Receipt Agent, or the Corporation 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 Receiptholders 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 Corporation 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, telecopied or electronically delivered before the meeting to the Corporation 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 Corporation and Subscription Receipt Agent may be Represented

The Corporation and the Subscription Receipt Agent, by their respective authorized agents, and the Counsel for the Corporation 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 proxyholder.

Any one or more of the powers or any combination of the powers in this Agreement stated to be exercisable by the Receiptholders by Extraordinary Resolution or otherwise may be exercised from time to time and the exercise of any one or more of such powers or any combination of powers from time to time shall not be deemed to exhaust the right of the Receiptholders to exercise such power or powers or combination of powers then or thereafter from time to time.

7.13 Minutes

Minutes of all resolutions and proceedings at every meeting of Receiptholders shall be made and duly entered in books to be provided from time to time for that purpose by the Subscription Receipt Agent at the expense of the Corporation, and any such minutes as aforesaid, if signed by the chairman or the secretary of the meeting at which such resolutions were passed or proceedings had or by the chairman or secretary of the next succeeding meeting held shall be prima facie evidence of the matters therein stated and, until the contrary is proved, every such meeting in respect of the proceedings of which minutes shall have been

CONCERNING THE SUBSCRIPTION RECEIPT AGENT

9.1 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.

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.

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 Corporation shall deposit with the Subscription Receipt 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 Corporation 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.

In the event of the Subscription Receipt Agent resigning or being removed as aforesaid or being dissolved, becoming bankrupt, going into liquidation or otherwise becoming incapable of acting hereunder, the Lead Underwriters, on behalf of the Underwriters, shall forthwith appoint a new subscription receipt agent unless a new subscription receipt agent has already been appointed by the Receiptholders; failing such appointment by the Lead Underwriters, on behalf of the Underwriters, the retiring Subscription Receipt 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 subscription receipt agent; but any new subscription receipt agent so appointed by the Lead Underwriters, on behalf of the Underwriters, or by the Court shall be subject to removal as aforesaid by the Receiptholders.

On any such appointment, the new subscription receipt agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as Subscription Receipt Agent hereunder. At the request of the Corporation 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.

(b) Upon the appointment of a successor subscription receipt agent, the Corporation shall promptly notify the Receiptholders thereof in the manner provided for in Article 10.

(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, provided that such corporation would be eligible for appointment as a successor subscription receipt agent under Section 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 Corporation and the Lead Underwriters, on behalf of the Underwriters, that at the time of execution and delivery hereof no material conflict of interest exists between its role as 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 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 Corporation and meeting the requirements set forth in Section 9.7(a). Notwithstanding the foregoing provisions of this Section 9.8(a), if any such material conflict of interest exists or hereafter shall exist, the validity and enforceability of this Agreement and the Subscription Receipt Certificates shall not be affected in any manner whatsoever by reason thereof.

(b) Subject to Section 9.8(a), the Subscription Receipt Agent, in its personal or any other capacity, may buy, lend upon and deal in securities of the Corporation and generally may contract and enter into financial transactions with the Corporation or any affiliated entity of the Corporation without being liable to account for any profit made thereby.
