1.6 Accounting Change

(a) For greater certainty, all accounting terms and financial covenants and thresholds (including Permitted Encumbrance thresholds) hereunder have been based upon GAAP in effect as of December 31, 2010 and do not reflect IFRS.  In the event that any Accounting Change occurs, the Borrower will provide notice thereof to the Agent (an "Initial Accounting Notice") together with a description of the nature of such Accounting Change.  Such notice shall describe the effect of such Accounting Change on the Borrower's current and immediately prior year's financial statements.  If the Borrower, the Agent or the Majority Lenders determines that any such change would cause an amount required to be determined for the purposes of any financial covenant in Section 8.3 or any other financial calculation hereunder (each a "Financial Calculation") to be materially different than the amount that would be determined without giving effect to such change, then the Borrower, the Agent or the Majority Lenders, as the case may be, shall notify the other Parties of such Accounting Change. Such notice (an "Accounting Change Notice") shall state whether the Borrower, the Agent or the Majority Lenders, as applicable, wish to revise the method of calculating one or more of the Financial Calculations (including the revision of any of the defined terms used in the determination of such Financial Calculation) in order that amounts determined after giving effect to such Accounting Change and the revised method of calculating such Financial Calculation will approximate the amount that would be determined without giving effect to such Accounting Change and without giving effect to the revised method of calculating such Financial Calculation; provided that if the Accounting Change Notice is delivered by the Agent or the Majority Lenders, they may request that the Borrower provide, within a reasonable time, the Accounting Change's effect on the Borrower's current and immediately prior year's financial statements.  The Initial Accounting Notice shall be delivered within 45 days after the end of the fiscal quarter in which the Accounting Change is implemented or, if such Accounting Change is implemented in the fourth fiscal quarter or in respect of an entire fiscal year, within 90 days after the end of such period. Following receipt of an Accounting Change Notice, either the Borrower or the Majority Lenders may provide a proposal to the other as to how to amend the provisions of this Agreement.

(b) If, pursuant to the Accounting Change Notice, the Borrower, the Agent or Majority Lenders, as applicable, does not indicate that it desires to revise the method of calculating one or more of the Financial Calculations, the Borrower or the Majority Lenders, as applicable, may within 30 days after receipt of the Accounting Change Notice, notify the Borrower or the Lenders, as applicable, that they wish to revise the method of calculating one or more of the Financial Calculations in the manner described above.

(c) If either the Borrower, the Agent or the Majority Lenders so indicate that they wish to revise the method of calculating one or more of the Financial Calculations, the Borrower and the Lenders shall in good faith attempt to agree on a revised method of calculating such Financial Calculations with the desired result that the criteria for evaluating the Borrower's financial condition or compliance with this Agreement shall be substantially the same after such Accounting Change as if such change had not been made (and they shall negotiate in good faith an amendment or amendments to this Agreement to give effect thereto which amendment shall for greater certainty require only Majority Lender approval thereto), provided that until such time

28

as any such agreement in writing has been reached, such method of calculation shall not be revised and all amounts to be determined thereunder shall be determined without giving effect to the Accounting Change.  For greater certainty, if no notice of a desire to revise the method of calculating the Financial Calculations in respect of an Accounting Change is given by either the Borrower, the Agent or the Majority Lenders within the applicable time period described above, then the method of calculating the Financial Calculations shall not be revised in response to such Accounting Change and all amounts to be determined pursuant to the Financial Calculations shall be determined after giving effect to such Accounting Change.

(d) If a Compliance Certificate is delivered in respect of a fiscal quarter or fiscal year in which an Accounting Change is implemented without giving effect to any revised method of calculating any of the Financial Calculations, and subsequently, as provided above, the method of calculating one or more of the Financial Calculations is revised in response to such Accounting Change, or the amounts to be determined pursuant to any of the Financial Calculations are to be determined without giving effect to such Accounting Change, the Borrower shall, as soon as reasonably possible, deliver a revised Compliance Certificate.  Any Event of Default which arises as a result of the Accounting Change and which is cured by this Section 1.6 shall be deemed to have never occurred.

1.7 Time

(B) the acceptance and purchase of Bankers' Acceptances (or the making of a BA Equivalent Advance) by such Lender if it is a Purchasing Lender and the delivery of the Discount Proceeds in respect of such Bankers' Acceptances (or BA Equivalent Advance) (less the applicable fees payable by the Borrower to such Lender pursuant to Section 5.4) for the account of the Borrower through the Agent at the Agent's Account for Payments; and

(iii) Letters of Credit: the issuance of Letters of Credit in Canadian Dollars or U.S. Dollars by a Fronting Lender on behalf of the Lenders or by the Lenders; provided that the aggregate of the Equivalent Amount in Canadian Dollars of all Letters of Credit outstanding hereunder shall not at any time exceed Cdn. $50,000,000.

3.3 Takeover

In the event the Borrower wishes to utilize Borrowings to fund, or to provide funds to any Subsidiary to fund, any offer to acquire (which shall include an offer to purchase securities, solicitation of an offer to sell securities, an acceptance of an offer to sell securities, whether or not the offer to sell was solicited, or any combination of the foregoing) outstanding securities of any person (other than a private issuer as defined under the Securities Act (Alberta) or a corporation or limited partnership whose shares or units are directly or indirectly held by one person) (the "Target") where, as of the date of the offer to acquire, the securities that are subject to the offer to acquire, together with the securities of such person that are beneficially owned, or over which control or direction is exercised, by the Borrower and its Subsidiaries and any person acting jointly or in concert with any thereof on the date that the offer to acquire is made, constitute in the aggregate the lesser of such percentage of outstanding securities as is considered to be a "takeover bid" under any law or regulation applicable to the Target and ten percent (10%) or more of all of the outstanding securities of that class of securities of the person (a "Takeover"), then either:

(a) Agreement of the Target: prior to or concurrently with delivery of any notice to the Agent pursuant to Section 3.4 requesting one or more Accommodations the proceeds of which are to be utilized to finance such Takeover, the Borrower shall provide to the Agent evidence satisfactory to the Agent (acting reasonably) that the board of directors or like body of the Target has approved or recommended to security holders acceptance of the Takeover; or

(b) No Conflict by Lenders:  the following steps shall be followed:

(i) at least seven (7) Business Days prior to the delivery of any notice to the Agent pursuant to Section 3.4 requesting Accommodations intended to be utilized for such Takeover, the President, the Chief Executive Officer, the Chief Operating Officer, the Chief Financial Officer or the Treasurer of the Borrower shall advise the Agent (who shall promptly advise an appropriate officer of each Lender) of the particulars of such Takeover in sufficient detail to enable such Lender to determine whether it has a conflict of interest if Accommodations from such Lender are utilized by the Borrower for such Takeover;

(ii) within five (5) Business Days of being so advised, each Lender shall notify the Agent of such Lender's determination, acting reasonably, as to whether such a conflict of interest exists (such determination to be made by such Lender in the exercise of its sole discretion having regard to such considerations as it deems appropriate), provided that in the event such Lender does not so notify the Agent within such five (5) Business Day period, such Lender shall be deemed to have notified the Agent that it has such a conflict of interest; and

(iii) the Agent shall promptly notify the President, the Chief Executive Officer, the Chief Operating Officer, the Chief Financial Officer or the Treasurer of the Borrower of each Lender's determination or deemed determination;

and in the event that any Lender has, or is deemed to have, such a conflict of interest, then upon the Agent so notifying the Borrower, such Lender shall have no obligation to provide Accommodations for such Takeover notwithstanding any other provision of this Agreement to the contrary; provided, however, that each other Lender (a "Takeover Lender") which has no such conflict of interest shall have an obligation, up to the amount of its Commitment, to provide Accommodations for such Takeover, and any such Accommodations provided for such Takeover

34

shall be provided by each Takeover Lender in accordance with the ratio that its Lender's Proportion bears to the aggregate of the Lender's Proportions of all the Takeover Lenders; and

(c) Takeover Loans:  if Accommodations are utilized for the purposes of a Takeover (a "Takeover Loan") and there are Lenders other than Takeover Lenders (the "Non-Takeover Lenders"), the Lender's Proportion of each Non-Takeover Lender shall be temporarily adjusted in accordance with Section 3.3(b) and, as applicable, subsequent Borrowings shall be funded firstly by Non-Takeover Lenders and subsequent repayments shall be applied firstly to Takeover Lenders, in each case until such time as the Lender's Proportion of each Takeover Lender and Non-Takeover Lender is equal to such Lender's Proportion in effect immediately prior to the advance of the Takeover Loan.

(iii) on any Conversion Date relating to Bankers' Acceptances:

(A) in the case of a Conversion from a Cdn. Prime Loan into Bankers' Acceptances, in order to satisfy the continuing liability of the Borrower to each Lender for the amount of the converted Borrowing, each such Lender shall receive for its own account the discounted proceeds of sale of the Bankers' Acceptances or the Discount Proceeds from the purchase by such Lender of such Bankers' Acceptances, as applicable, and the Borrower shall on the Conversion Date pay to each such Lender, through the Agent at the Agent's Account for Payments, the difference between the principal amount of the converted Borrowing and the discounted proceeds of sale or the Discount Proceeds, as applicable, from such Bankers' Acceptances together with the fee to which each such Lender is entitled pursuant to Section 5.4;

(C) in the case of a Conversion from Bankers' Acceptances to another type of Accommodation, in order to satisfy the continuing liability of the Borrower to each Lender for an amount equal to the face amount of such Bankers' Acceptances, the Agent and each such Lender shall record the obligation of the Borrower to each such Lender as a Borrowing of the type into which the maturing Bankers' Acceptance has been converted; provided that in the case of a conversion into U.S. Dollars, the Borrower shall be responsible for payment to such Lender of an amount in Canadian Dollars equal to the principal amount of the Bankers' Acceptance being converted.

(d) Waiver of Presentment and Other Conditions:  The Borrower waives presentment for payment and, except to the extent of the gross negligence or willful misconduct of the Lenders referred to in the Power of Attorney Terms – Bankers' Acceptances set out in Schedule I, any other defence to payment of any amounts due to any Lender in respect of a Bankers' Acceptance accepted and, if applicable, purchased by it pursuant to this Agreement which might exist solely by reason of such Bankers' Acceptance being held, at the maturity thereof, by such Lender in its own right and the Borrower agrees not to claim any days of grace if such Lender as holder sues the Borrower on the Bankers' Acceptance for payment of the amount payable by the Borrower thereunder.  On the specified maturity date of a Bankers' Acceptance, or such earlier date as may be required or

37

permitted pursuant to the provisions of this Agreement, the Borrower shall pay the Agent on behalf of the Lender that has accepted such Bankers' Acceptance the full face amount of such Bankers' Acceptance or, if applicable, shall effect a Conversion or Rollover of such Bankers' Acceptances and make such additional payments, if any, as are required pursuant to Section 3.6(c).

(e) Terms of Each Bankers' Acceptance:  Each Bankers' Acceptance shall:

(i) have a maturity date which shall be on a Business Day;

(iii) be denominated in the amount of Cdn. $100,000 and whole multiples thereof; and

(iv) be in the standard form of each Lender;

It is the intention of the parties that pursuant to the Depository Bills and Notes Act (Canada) ("DBNA"), all Bankers' Acceptances accepted by the Lenders (other than the Old System Issuers) under this Agreement shall be issued in the form of a "depository bill" (as defined in the DBNA), deposited with the Canadian Depository for Securities Ltd. ("CDS") and will be made payable to CDS & Co.  In order to give effect to the foregoing, the Agent for the Lenders (other than the Old System Issuers) shall, subject to the approval of the Borrower and the Lenders (other than the Old System Issuers), establish and notify the Borrower and the Lenders (other than the Old System Issuers) of any additional procedures, consistent with the terms of this Agreement, as are reasonably necessary to accomplish such intention, including, without limitation:

(A) any instrument held by the Agent for the purposes of Bankers' Acceptances shall have marked prominently and legibly on its face and within its text, at or before the time of issue, the words "This is a depository bill subject to the Depository Bills and Notes Act (Canada)";

(B) any reference to the authentication of the Bankers' Acceptance will be removed; and

(C) any reference to "bearer" will be removed and such Bankers' Acceptance shall not be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it.

Prime Loan pursuant to Section 3.12.

38

(h) Lenders to Purchase:  The Borrower shall be entitled to elect to have:

(i) each and every Lender purchase all, but not less than all, of any Bankers' Acceptances issued by the Borrower and accepted by each such Lender and forming a part of the same issue of Bankers' Acceptances; or

(ii) each and every Schedule II Lender purchase all, but not less than all, of any Bankers' Acceptances issued by the Borrower and accepted by each such Lender and forming a part of the same issue of Bankers' Acceptances;

in each case on any Drawdown Date, Conversion Date or Rollover Date by advising the applicable Lenders of such election in any written notice of Borrowing by way of Bankers' Acceptances in the form of Schedule B or notice of Conversion of a Borrowing to Bankers' Acceptances in the form of Schedule D or any notice of Rollover of Bankers' Acceptances in the form of Schedule E.  If the Borrower fails to advise the applicable Lenders of any such election in any such written notice, it shall be deemed not to have elected to have any of such Lenders purchase such Bankers' Acceptances except in the case of Old System Issuers which shall purchase all Bankers' Acceptances accepted by them.

(i) BA Equivalent Advances:  Notwithstanding the foregoing provisions of this Section 3.6, a Non-Acceptance Lender shall, in lieu of accepting Bankers' Acceptances, make a BA Equivalent Advance. The amount of each BA Equivalent Advance shall be equal to the Discount Proceeds which would be realized from a hypothetical sale of those Bankers' Acceptances which, but for this Section 3.6(i), such Lender would otherwise be required to accept as part of such an Accommodation by way of Bankers' Acceptances.  To determine the amount of such Discount Proceeds, the hypothetical sale shall be deemed to take place at the Non-Acceptance Discount Rate.  Any BA Equivalent Advance shall be made on the relevant Drawdown Date, Conversion Date or Rollover Date, as the case may be and shall remain outstanding for the term of the Bankers' Acceptances issued concurrently therewith.  Concurrently with the making of a BA Equivalent Advance, a Non-Acceptance Lender shall be entitled to deduct therefrom an amount equal to the acceptance fee which, but for this Section 3.6(i), such Lender would otherwise be entitled to receive as part of such issue of Bankers' Acceptances. The BA Equivalent Advance shall accrue interest at a rate per annum equal to the Non-Acceptance Discount Rate for such Bankers' Acceptance for the term of such BA Equivalent Advance. Upon the maturity date for such Bankers' Acceptances, the Borrower shall pay to each Non-Acceptance Lender, in satisfaction of the BA Equivalent Advance and interest accrued thereon, an amount equal to the face amount of the Bankers' Acceptance which, but for this Section 3.6(i), such Lender would otherwise have been required to accept as part of such Accommodation by way of Bankers' Acceptance, failing which such amount shall be converted to a Cdn. Prime Loan.

All BA Equivalent Advances made by a Non-Acceptance Lender shall, if requested by such Lender, be evidenced by promissory notes of the Borrower in form and substance satisfactory to the Borrower and such Lender, each acting reasonably.

All references herein to "Bankers' Acceptances" shall, unless otherwise expressly provided herein or unless the context otherwise requires, be deemed to include BA Equivalent Advances made by a Non-Acceptance Lender as part of an Accommodation by way of Bankers' Acceptances.

(i) any drawing under such Letter of Credit shall be made concurrently with drawings under all other Letters of Credit forming part of such Issuance;

Prime Loan (for any such payments made in Cdn. Dollars) or a U.S. Base Rate Loan (for any such payments made in U.S. Dollars), with the proceeds of such advance being applied against the Borrower's obligations to reimburse the Lenders for payment made under the Letters of Credit, and the provisions hereof relating to such Cdn. Prime Loans or U.S. Base Rate Loans, as applicable (including interest to be calculated thereon) shall apply thereto.  Each Lender shall forthwith advise the Agent of any demand by the beneficiary of a Letter of Credit for payment by such Lender under such Letter of Credit and of any payment made by it on such Letter of Credit to the beneficiary thereof.  In determining whether to pay under a Letter of Credit, a Lender shall be responsible only to determine that the documents and certificates required to be delivered under such Letter of Credit have been delivered and that they comply on their face with the requirements of such Letter of Credit.

Credit by any applicable law, regulation, treaty, official directive or regulatory requirement now or hereafter in effect (whether or not having the force of law).

(c) Letter of Credit Participations:  Each Fronting Lender irrevocably grants, and, in order to induce each Fronting Lender to issue any Fronted Letters of Credit hereunder, each Lender irrevocably accepts and hereby purchases from such Fronting Lender on the terms and conditions hereinafter stated, for its own account and risk, an undivided interest (equal to the Lender's Proportion of such Lender) in such Fronting Lender's obligations and rights under each Fronted Letter of Credit issued by such Fronting Lender pursuant to this Section 3.9 and the amount of each draft paid by such Fronting Lender thereunder.  Each Lender unconditionally and irrevocably agrees with each Fronting Lender that, on or before the close of business of such Fronting Lender on each day on which a draft is paid under a Fronted Letter of Credit for which such Fronting Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, including, without limitation, pursuant to Section 3.9(i) (a "Participation Date"), such Lender will pay to the Agent for the account of such Fronting Lender at the Agent's Branch of Account the Lender's Proportion of such Lender of any such unpaid amount.  Each Fronting Lender shall notify the Agent who shall notify each Lender of the occurrence of a Participation Date and the amount payable by such Lender to the Agent based on the Lender's Proportion of such Lender.  Any such notice may be oral if promptly confirmed in writing (including telecopy or electronic mail).  If any Lender fails to make any such payment on the day on which such Lender receives notice as provided above, then interest shall accrue on such Lender's obligation to make such payment during the period from such day to the day such Lender makes such payment (or, if earlier, the date on which the Borrower reimburses the applicable Fronting Lender as required pursuant to Section 3.9(i)), at a rate determined by the Agent (such rate to be conclusive and binding on such Lender or the Borrower as the case may be) in accordance with the Agent's usual banking practice for similar advances to financial institutions of like standing to such Lender.

(d) Repayment of Lenders:  Upon and only upon receipt by a Fronting Lender of funds from the Borrower in full or partial reimbursement of any draft paid under a Fronted Letter of Credit with respect to which any Lender has theretofor paid the Agent for the account of such Fronting Lender in full for such Lender's participation pursuant to Section 3.9(c) and in full or partial payment of interest on such draft paid under a Fronted Letter of Credit, such Fronting Lender will pay to the Agent for the account of such Lender, in the same funds as those received by such Fronting Lender, or net against any then due obligation of such Lender under Section 3.9(c) to make any payment to such Fronting Lender, the Lender's Proportion of such Lender of such funds.

(e) Role of the Fronting Lenders:  Each Fronting Lender will exercise and give the same care and attention to each Fronted Letter of Credit issued by it pursuant to this Section 3.9 as it gives to its other letters of credit and similar obligations, and such Fronting Lender's sole liability to the Lenders shall be to promptly return to the Agent for the account of each such Lender, such Lender's Lender's Proportion of any payments made to such Fronting Lender by the Borrower pursuant to Section 3.9(c) where the Borrower has made a payment to such Fronting Lender pursuant to Section 3.9(d).  Each Lender agrees that, in paying any drawing under a Fronted Letter of Credit, the applicable Fronting Lender shall not have any responsibility to obtain any document (other than as expressly required by such Fronted Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of any person delivering any such document.  Neither any Fronting Lender nor any of its representatives, officers, employees or agents shall be liable to any Lender for:

43

(i) any action taken or omitted to be taken in connection herewith at the request or with the approval of the Majority Lenders;

(ii) any action taken or omitted to be taken in connection with any Fronted Letter of Credit in the absence of gross negligence or willful misconduct; or

(iii) the execution, effectiveness, genuineness, validity, or enforceability of any Fronted Letter of Credit, or any other document contemplated thereby.

No Fronting Lender shall incur any liability by acting in reliance upon any notice, consent, certificate, statement or other writing (which may be a bank wire, telex or similar writing) believed by it to be genuine or to be signed by the proper party or parties.

(f) Each Lender's Obligations Absolute:  Each Lender acknowledges that its obligations to each Fronting Lender under this Section 3.9, including the obligation to purchase and fund a participation in the obligations and rights of a Fronting Lender under each Fronted Letter of Credit and any drafts paid by it for which it has not been fully reimbursed by the Borrower, are absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation:

(i) the occurrence and continuance of any Default or Event of Default;

(ii) any failure or inability of any other Lender to purchase or fund such a participation hereunder; or

(iii) any other failure by any other Lender to fulfill its obligations hereunder.

Each payment by a Lender to a Fronting Lender shall be made, without any offset, compensation, abatement, withholding or reduction whatsoever.

(g) Reinstatement and Survival:  Notwithstanding anything herein to the contrary, if a Fronting Lender is required at any time whether before or after any Maturity Date to make any payment under a Fronted Letter of Credit, each Lender shall pay over to the Agent in accordance with the provisions of this Section 3.9 and for the account of such Fronting Lender, the amount of the Lender's Proportion of such Lender of such amount.  If a Fronting Lender is required at any time to return to the Borrower or to a trustee, receiver, liquidator, custodian or other similar official any portion of the payments made by or on behalf of the Borrower to such Fronting Lender in reimbursement of the Borrower's obligations in respect of such Fronted Letter of Credit and interest thereon, each Lender shall, on demand of such Fronting Lender forthwith pay over to the Agent for the account of such Fronting Lender the Lender's Proportion of such Lender of such amount, plus interest thereon from the day such demand is made to the day such amount is returned by such Lender to such Fronting Lender at a rate determined by the Agent (such rate to be conclusive and binding on such Lender or the Borrower as the case may be) in accordance with the Agent's usual banking practice for similar advances to financial institutions of like standing to such Lender.

(h) Procedure for Issuance and Renewal of Letters of Credit:

(i) The Borrower may request that a Fronting Lender issue a Fronted Letter of Credit pursuant to Section 3.9 by delivering a notice to the Agent pursuant to Section 3.4(e) and

44

by delivering to a Fronting Lender at such Fronting Lender's Branch of Account a letter of credit application and indemnity in such Fronting Lender's then customary form (as such form may be modified from time to time, the "Letter of Credit Application"), completed to the satisfaction of such Fronting Lender together with the proposed form of such Fronted Letter of Credit (which shall comply with the applicable requirements set forth herein) and such other certificates, documents and other papers and information as such Fronting Lender may reasonably request; provided that in the event of a conflict between this Agreement and the Letter of Credit Application, this Agreement shall govern with respect to such conflict.

(ii) Within three (3) Business Days following the date on which any Fronting Lender shall have received the notice pursuant to Section 3.4(e) and such Fronting Lender shall have received the applicable Letter of Credit Application including the proposed form of the Fronted Letter of Credit and such additional certificates, documents and other papers and information as such Fronting Lender may have reasonably requested in satisfaction of all conditions to the issuance thereof, such Fronting Lender shall, provided all other conditions precedent contained in this Agreement have been complied with, issue such Fronted Letter of Credit.

(iii) The Borrower may request the extension or renewal of a Fronted Letter of Credit issued under this Section 3.9 by giving written notice to the applicable Fronting Lender at least three (3) Business Days prior to the then current expiry date of such Fronted Letter of Credit (provided that the applicable Fronting Lender may accommodate notices on shorter notice in its sole discretion).  If all conditions precedent contained in this Agreement (including the payment of the necessary fees under Section 5.5) shall have been fulfilled as required thereby and subject to the other terms of this Agreement, the applicable Fronting Lender shall promptly issue such extension or renewal.

(i) Reimbursement of the Agent:

In the event that any drawing shall be made under any Fronted Letter of Credit issued under this Section 3.9:

(i) the applicable Fronting Lender shall promptly notify the Agent who shall promptly notify the Borrower of such payment and of the amount thereof;

(ii) the Borrower shall pay to the Agent for the account of such Fronting Lender the amount of any such drawing on the date of such drawing, failing which the payment by such Fronting Lender of such drawing shall constitute the making of a Cdn. Prime Loan or U.S. Base Rate Loan, as applicable, to the Borrower by each Lender according to the Lender's Proportion of such Lender of such amount (without limiting each Lender's obligations to such Fronting Lender, including under Section 3.9(c));

(iii) the Agent shall notify each Lender by telecopier or by telephone (confirmed by telecopier) of such drawing; and

(iv) immediately upon receipt of such notice, each Lender shall make such Lender's Lender's Proportion of such amount in Cdn. Dollars or U.S. Dollars, as applicable, available to the Agent for the account of the applicable Fronting Lender by wire transfer of immediately

45

available funds to the Agent's Account for Payments for the account of such Fronting Lender.

(j) Designation and Termination of Fronting Lenders:

(i) The Borrower shall be entitled from time to time to terminate any Fronting Lender as a Fronting Lender by providing a written notice of such termination to the Agent and such Fronting Lender and, concurrently with such termination or if a Fronting Lender provides a notice to the Borrower pursuant to Section 3.9(j)(iv), designate another Lender as a Fronting Lender by providing a written notice to the Agent designating such Lender to be a Fronting Lender and which notice shall include the consent to such designation of the Agent and such Lender; provided that at any one time there shall be no more than two Fronting Lenders which are eligible to issue Fronted Letters of Credit under this Section 3.9.

(ii) Each Fronting Lender shall be entitled to conduct an annual review of its status as a Fronting Lender and shall be entitled to resign as a Fronting Lender by providing a written notice of such resignation not earlier than 30 days prior to and not later than 30 days after any Anniversary Date.

(iii) In the event a Fronting Lender is terminated as a Fronting Lender pursuant to Section 3.9(j)(i) and there are Fronted Letters of Credit outstanding which were issued by such Fronted Lender, the Borrower shall use its reasonable commercial efforts to replace all such Fronted Letters of Credit with Fronted Letters of Credit issued by any new or continuing Fronting Lenders and, upon such replacement, such Fronting Lender shall cease to be a Fronting Lender.

(iv) In the event that a Fronting Lender has notified the Borrower in writing that:

(A) pursuant to Section 10.3, it is no longer able to issue Letters of Credit on behalf of the Lenders; or

(B) pursuant to Section 3.9(j)(ii), it is resigning as a Fronting Lender,

then such Fronting Lender shall not be required to issue additional Fronted Letters of Credit and, in any such case and if the Fronting Lender requests in writing, the Borrower shall use its reasonable commercial efforts to replace all Fronted Letters of Credit issued by such Fronting Lender as soon as practicable with Fronted Letters of Credit issued by the Fronting Lender designated by the Borrower to replace such Fronting Lender pursuant to Section 3.9(j)(i) or any continuing Fronting Lenders.

(v) Where a Fronting Lender is terminated pursuant to Section 3.9(j)(i), resigns pursuant to Section 3.9(j)(ii) or provides notice to the Borrower pursuant to Section 10.3 that it is no longer able to issue Letters of Credit on behalf of the Lenders, such Fronting Lender shall remain a Fronting Lender under all Fronted Letters of Credit issued by it until all such Fronted Letters of Credit have been either replaced, expired or been presented for payment and all payments required to be made to such Fronting Lender by the Borrower and/or the other Lenders pursuant to this Section 3.9 as a result of any payment made under any Fronted Letter of Credit issued by such Fronting Lender have been made.

46

3.10 Notice of Repayment

The Borrower shall give the Agent, at the Agent's Branch of Account, prior written notice of each repayment of Borrowings in accordance with the same period of notice required pursuant to Section 3.4 for the initial drawdown of the basis of Borrowing being repaid, such notice to be substantially in the form of Schedule B.  Notwithstanding the foregoing, a Bankers' Acceptance and a BA Equivalent Advance shall, subject to Section 4.5, only be repaid on its maturity date and a Libor Loan shall, subject to Sections 4.5 and 10.5, only be repaid on the last day of the Libor Interest Period related thereto.

3.11 Pro-Rata Treatment of Borrowings

(a) Pro-Rata Borrowings:  Subject to Section 3.3, Section 3.9, Section 3.11(b) and Section 3.11(c), each Accommodation and each basis of Borrowing shall be made available by each Lender and all repayments and reductions in respect thereof shall be made and applied in a manner so that the proportion of Borrowings outstanding to such Lender will, to the extent possible, thereafter be in the same proportion as such Lender's Proportion.  The Agent is authorized by the Borrower and each Lender to determine, in its sole and unfettered discretion, the amount of Borrowings and each basis of Borrowing to be made available by each Lender and the application of repayments and reductions of Borrowings to give effect to the provisions of this Section 3.11(a), and Section 6.2; provided that no Lender shall, as a result of any such determination, have Borrowings outstanding in an amount which is in excess of the amount of its Commitment.

(b) Where Different Maturity Dates:  If, at any time there are Lenders with different Maturity Dates, all Lenders will share in Accommodations based on their Lender's Proportion except to the extent the particular Accommodation requested has a maturity date after the Maturity Date of a Lender, in which case only those Lenders with a Maturity Date later than the maturity date of the requested Accommodation will be required to participate in providing such Accommodation and the Borrower may request a similar Accommodation, to the extent permitted hereunder, from the other Lenders with a maturity date occurring on or before the Maturity Date of such Lenders.  Each determination by the Agent of a Lender's Lender's Proportion shall be prima facie evidence thereof.

(c) Agent's Discretion on Allocation:  In the event it is not practicable to:

(i) allocate each basis of Borrowing in accordance with Section 3.11(a) by reason of the occurrence of circumstances described in Section 10.2, Section 10.3 or Section 10.4; or

(ii) allocate Bankers' Acceptances and BA Equivalent Advances to each Lender in accordance with Section 3.11(a) such that the aggregate amount of Bankers' Acceptances required to be accepted or purchased or BA Equivalent Advances required to be made by such Lender hereunder is in a whole multiple of Cdn. $100,000;

the Agent is authorized by the Borrower and each Lender to make such allocation as the Agent determines in its sole and unfettered discretion may be equitable in the circumstances but no Lender shall, as a result of any such allocation, have Borrowings outstanding in an amount which is in excess of the amount of its Commitment.

47

(d) Further Assurances by Borrower:  To the extent reasonably possible, the Borrower and each Lender agrees to be bound by and to do all things necessary or appropriate to give effect to the provisions of this Section 3.11.

3.12 Conversions

The Borrower may, during the term of this Agreement and, in the case of a conversion into a Libor Loan or a Bankers' Acceptance, if no Default or Event of Default has occurred which is continuing, upon giving the Agent at the Agent's Branch of Account prior written notice of a Conversion in accordance with the period of notice and other requirements set out in Section 3.4 (other than delivery of a notice in the form of Schedule B ) in respect of the basis of Borrowing to which any Borrowing is being converted, such notice to be substantially in the form of Schedule D, convert any basis of Borrowing (other than a Letter of Credit) to another basis of Borrowing (other than a Letter of Credit); provided that a Bankers' Acceptance may only be converted on its maturity date and a Libor Loan may only be converted on the last day of the Libor Interest Period applicable to such Libor Loan or on any other day if the Borrower pays all amounts payable in respect thereof pursuant to Sections 4.5 or 10.5, respectively.  On each Conversion Date, the Borrower shall be required to repay to the Agent the basis of Borrowing which is being converted (subject to any netting procedures of the Agent in respect of conversions in accordance with its usual practice) and, subject to the provisions of this Agreement and any such netting procedures, the Lenders shall be required to make available to the Borrower the Borrowings into which such basis of Borrowing is being converted.

3.13 Rollovers

The Borrower may, during the term of this Agreement, Rollover all or any portion of a Bankers' Acceptance on its maturity date or all or any portion of a Libor Loan for an additional Libor Interest Period subsequent to the initial or any subsequent Libor Interest Period, upon giving the Agent at the Agent's Branch of Account prior written notice thereof, substantially in the form of Schedule E, and in accordance with the period of notice and other requirements set out in Section 3.4 applicable to Bankers' Acceptances or Libor Loans (other than delivery of a notice in the form of Schedule B), unless immediately prior to the issue of any such Bankers' Acceptances or the commencement of any subsequent Libor Interest Period, a Default or an Event of Default shall have occurred and be continuing, in which event the Borrower shall be deemed to have converted such Bankers' Acceptance into a Cdn. Prime Loan or such Libor Loan to a U.S. Base Rate Loan, in each case pursuant to Section 3.12 and the Borrower shall not be entitled to issue such Bankers' Acceptances or continue such Libor Loan subsequent to the existing Libor Interest Period.  In the event notice of a Rollover of an existing Bankers' Acceptance or Libor Loan is not given pursuant to this Section 3.13 or notice of a Conversion of such existing Bankers' Acceptance or Libor Loan is not given pursuant to Section 3.12, such Bankers' Acceptance shall be converted into a Cdn. Prime Loan on the maturity date of such Bankers' Acceptance and such Libor Loan shall be converted to a U.S. Base Rate Loan on the last day of the Libor Interest Period applicable to such existing Libor Loan.  The Rollover of a Libor Loan to another Libor Loan shall not constitute a repayment or prepayment hereunder.

3.14 Notices Irrevocable

All notices delivered by the Borrower hereunder shall be irrevocable and shall oblige the Borrower to take the action contemplated on the date specified therein.

48

3.15 Extension of Maturity Date

(a) Request for Extension:  The Borrower may, from time to time, request an extension of the Maturity Date of each Lender who has not yet refused to extend the Maturity Date (or been deemed to have refused to extend the Maturity Date) pursuant to any prior Request for Extension (each, a "Requested Lender") by sending to the Agent the Request for Extension, not later than the sixtieth day and not earlier than the ninetieth day prior to any anniversary of October 29, 2010 (each, an "Anniversary Date") and the Agent shall forthwith, and in any event within four (4) Business Days, notify each Requested Lender of such request.  In this Section 3.15, the Maturity Date of the Requested Lenders is referred to as the "Subject Maturity Date".  Each Requested Lender shall advise the Agent as to whether it agrees to extend the Subject Maturity Date in accordance with any such Request for Extension within thirty (30) days of the delivery by the Borrower to the Agent of a Request for Extension, provided that in the event such Requested Lender does not so advise the Agent within such thirty (30) day period, such Requested Lender shall be deemed to have advised the Agent that it is not prepared to extend the Subject Maturity Date.  Within four (4) Business Days of the Agent receiving from each Requested Lender its decision with respect to extending the Subject Maturity Date, the Agent shall, subject to Section 3.15(c), advise the Borrower of each Requested Lender's decision.

(b) Repayment or Replacement by Borrower:  Subject to Section 3.15(c), if a Requested Lender does not agree to extend the Subject Maturity Date applicable to it (such Lender being a "Non-Extending Lender" and any Requested Lender agreeing to extend the Subject Maturity Date applicable to it being an "Extending Lender") the Borrower may, but is not obligated, to:

(i) so long as there exists no Event of Default and subject to Section 10.5, repay all Borrowings and other amounts owing hereunder to any Non-Extending Lender on or prior to the Subject Maturity Date and upon such payment any Non-Extending Lender shall cease to be a Lender hereunder and each such Non-Extending Lender's Commitment shall be terminated and the Total Commitment reduced accordingly; or

(ii) arrange for replacement lender(s) (which may be one or more of the Lenders) to replace each Non-Extending Lender's Borrowings and its Commitment; provided that any such replacement lender (if it is not a Lender) shall have been approved by the Agent and each Fronting Lender (each such approval not to be unreasonably withheld) and shall be novated into the Loan Documents in the place and stead of the Non-Extending Lender by execution of all necessary documentation on or prior to the Subject Maturity Date and in respect of which the Lenders shall do all things and make all such adjustments as are reasonably necessary to give effect to any such replacement.

(c) Non-Extension:  The Subject Maturity Date shall not be extended in accordance with Section 3.15(a) if Requested Lenders holding less than sixty-six and two-thirds percent (66 2/3%) of the Commitments of all Requested Lenders agree to extend the Subject Maturity Date pursuant to any Request for Extension.  In such case, the Subject Maturity Date for all Requested Lenders shall not be extended.

(d) Extension for all Requested Lenders:  If all Requested Lenders agree to extend the Subject Maturity Date pursuant to a Request for Extension, then the Subject Maturity Date shall be extended for the period requested by the Borrower, provided that following the granting of any such extension, the Maturity Date of the Extending Lenders shall not be more than three years from the applicable Anniversary Date.

49

(e) Partial Extension:  If, with respect to any Request for Extension, the provisions of Section 3.15(c) or 3.15(d) are not applicable and there are Non-Extending Lenders under Section 3.15(b), then:

(i) the Subject Maturity Date for those Requested Lenders agreeing to extend the Subject Maturity Date shall be extended for the period requested by the Borrower, provided that following the granting of any such extension, the Maturity Date of the Extending Lenders and any replacement lenders under Section 3.15(b)(ii) shall not be more than three years from the applicable Anniversary Date; and

(ii) for those Non-Extending Lenders, the Subject Maturity Date of all such Lenders shall not be extended.

(f) Maturity Date:  Any Subject Maturity Date which shall be extended pursuant to Sections 3.15(d) or 3.15(e), shall constitute the Maturity Date for the applicable Extending Lender for all purposes of this Agreement after such extension.

(g) Independent Decision:  The Borrower understands that consideration of any Request for Extension constitutes an independent credit decision which each Lender retains the absolute and unfettered discretion to make and that no commitment in this regard is hereby given by any Lender.

(h) Default or Event of Default:  Notwithstanding the foregoing, the Borrower shall not be entitled to make a Request for Extension or accept any offer made by the Agent on behalf of the Extending Lenders to extend the Subject Maturity Date if a Default or Event of Default has occurred and is continuing or it is unable to make the representations and warranties as required pursuant to Section 2.2 at such time.

3.16 Increase of Total Commitment

The Borrower may at any time and from time to time add additional financial institutions hereunder as Lenders or, with the consent of the applicable Lender, increase the Commitment of a Lender and thereby increase the Total Commitment provided that at the time of any such addition:

(a) no Default or Event of Default has occurred and is continuing;

(b) the Total Commitment (as increased) does not exceed Cdn. $1,250,000,000;

(c) the Agent and each Fronting Lender has consented to such financial institution becoming a Lender, if it is not already a Lender, or, in the case of an existing Lender, increasing its Commitment, such consent not to be unreasonably withheld or delayed;

(d) the Lender's Commitment of a new financial institution being added as a Lender pursuant to this Section 3.16 shall be no less than Cdn. $25,000,000;

(e) concurrently with the addition of a financial institution as an additional Lender or the increase of a Lender's Commitment, such financial institution or Lender, as the case may be, shall purchase from each Lender such portion of the Borrowings of each such Lender as is necessary to ensure that all Borrowings of all Lenders and including therein such additional financial institution, are in accordance with the Lender's Proportion of all such Lenders (including the new financial

50

institution) and such financial institution shall execute such documentation as is required by the Agent, acting reasonably, to novate such financial institution as a Lender hereunder; and

(f) the Borrower has provided to the Agent a certified copy of a directors' resolution of the Borrower authorizing any such increase in the Total Commitment (which may be the original directors' resolution authorizing the credit facility provided hereunder) together with a legal opinion with respect thereto in substantially the same form as the opinion of the Borrower's counsel delivered in connection with the closing of the credit facility provided hereunder.

ARTICLE 4

REPAYMENT AND PREPAYMENT

4.1 Reduction of Commitment and Repayment of Borrowings

On the applicable Maturity Date of each Lender, the Borrower shall repay all Borrowings then outstanding to such Lender together with all other amounts owing hereunder to such Lender and the Commitment of such Lender shall be reduced to zero.  The Borrower shall ensure that Libor Loans, Bankers' Acceptances, BA Equivalent Advances and Letters of Credit either mature or expire in sufficient amounts to facilitate the reduction of the Commitment of such Lender and the making of payments required pursuant to this Section 4.1.

If, notwithstanding the foregoing, any Letters of Credit or Bankers' Acceptances remain outstanding on the Maturity Date, the Borrower shall pay to the Agent for the account of the Lenders obligated thereunder, (a) in respect of Bankers' Acceptances, the amount determined by such Lender, acting reasonably (and advised to the Agent), to be the amount required to be paid on such date of payment in order to yield to such Lender the face amount of any such Bankers' Acceptance on the maturity date thereof and (b) in respect of Letters of Credit, cash collateral for each unexpired Letter of Credit equal to the maximum amount thereof in the respective currency in which the relevant Letter of Credit is denominated.  With respect to Letters of Credit, such cash collateral shall be applied to satisfy the obligations of the Borrower for such Letters of Credit as payments are made thereunder.  If after expiry or cancellation of all Letters of Credit for which the cash collateral is held, any excess cash collateral remains, such excess shall be promptly paid to the Borrower so long as no Default or Event of Default is then continuing.

4.2 Repayment of Borrowings due to Exchange Rate Fluctuations

If due to exchange rate fluctuations the amount of Borrowings (determined in Cdn. Dollars with all such Borrowings denominated in U.S. Dollars being converted to the Equivalent Amount in Cdn. Dollars) outstanding to any Lender is, on any Interest Date, Drawdown Date, Conversion Date or Rollover Date, as applicable, in excess of the amount of such Lender's Commitment, the Agent shall advise the Borrower in writing of the amount of such excess and the Borrower shall, if requested by the Agent and within five (5) Business Days of any such request, repay, provide cash cover to be held by the Agent on behalf of such Lender in the manner provided for in Section 9.7 or otherwise reduce a portion of such Borrowings to the extent of the amount of such excess.

4.3 Cancellation of Commitment and Prepayment

The Borrower may, without penalty or premium, at any time during the term of this Agreement upon three (3) Business Days prior written notice substantially in the form of Schedule B, cancel all of the Total Commitment or any portion thereof in minimum amounts of Cdn. $10,000,000 and

51

whole multiples of Cdn. $1,000,000 thereafter if, on or prior to the last day of such notice period, the Borrower has:

(a) prepaid or otherwise reduced the Borrowings outstanding to each Lender in an amount equal to the amount by which the Borrowings outstanding to such Lender would otherwise be in excess of such Lender's Commitment immediately after the reduction of the Total Commitment provided for in such notice; and

(b) paid all accrued interest and other charges and fees in respect of the Borrowings being repaid or reduced as aforesaid.

Any such notice of cancellation is irrevocable and the amount of the Commitment of each Lender so cancelled and reduced may not be reinstated hereunder.  Notwithstanding the foregoing, the Borrower shall be entitled to exercise its rights under this Section 4.3 in respect of the Commitment of all Lenders who have the same Maturity Date without being required to concurrently cancel the Commitments of any other Lenders.

4.4 Cancellation of a Lender's Commitment

If:

(a) a Lender does not agree to make Borrowings available in respect of a Takeover;

(b) any payment is required to be made by the Borrower to a Lender (but not to all of the Lenders) pursuant to Section 6.3;

(c) Additional Compensation is payable by the Borrower to a Lender (but not to all of the Lenders) pursuant to Section 10.2;

(d) a Lender is affected by the provisions of Section 10.3 and all of the other Lenders are not so affected;

(e) any Lender withholds its consent to any amendment, consent, waiver or other determination requested by the Borrower which require the approval of all of the Lenders and as a consequence thereof such amendment, consent or determination cannot be obtained; or

(f) a Lender becomes a Defaulting Lender;

(any such Lender being called herein the "Affected Lender") then the Borrower may so long as no Default or Event of Default has occurred and is continuing:

(i) upon at least five (5) Business Days prior written notice to the Agent, irrevocably cancel all but not part of the Affected Lender's Commitment if on or prior to the last day of such notice period the Borrower has prepaid or otherwise reduced all Borrowings outstanding to such Lender, and paid all accrued interest and other charges and fees in respect of such Borrowings; or

(ii) with the consent of the Agent and each Fronting Lender, each such consent not to be unreasonably withheld or delayed, and within thirty (30) days of any such cancellation, arrange for a replacement lender (which may be one of the Lenders in which case no

52

consent of the Agent shall be required) to replace the Affected Lender's Commitment and any such replacement lender shall be novated into the Loan Documents in the place and stead of the Affected Lender.

4.5 Early Repayment of Bankers' Acceptances and Libor Loans and Letters of Credit

The Borrower shall not cancel all or any portion of the Total Commitment pursuant to Sections 4.3 or 4.4 if the applicable Borrowings required to be repaid to a Lender as a result thereof include Libor Loans with a Libor Interest Period ending subsequent to the date of such cancellation, Bankers' Acceptances accepted by such Lender with a maturity date falling subsequent to the date of such cancellation or Letters of Credit with an expiry date falling subsequent to the date of such cancellation unless, on the date of such cancellation, the Borrower pays to the Agent at the Agent's Account for Payments for the account of such Lender (a) in respect of Libor Loans, the amount required to be paid pursuant to Section 10.5, (b) in respect of Bankers' Acceptances, the amount determined by such Lender, acting reasonably (and advised to the Agent), to be the amount required to be paid on such date of cancellation in order to yield to such Lender the face amount of any such Bankers' Acceptance on the maturity date thereof and (c) in respect of Letters of Credit, cash collateral for each unexpired Letter of Credit equal to the maximum amount thereof in the respective currency in which the relevant Letter of Credit is denominated.  With respect to Letters of Credit, such cash collateral shall be applied to satisfy the obligations of the Borrower for such Letters of Credit as payments are made thereunder.  If after expiry or cancellation of all Letters of Credit for which the cash collateral is held, any excess cash collateral remains, such excess shall be promptly paid to the Borrower so long as no Default or Event of Default is then continuing.

4.6 Evidence of Indebtedness

The Agent shall open and maintain on the books of the Agent at the office of the Agent where the Agent's Account for Payments is from time to time maintained, accounts and records (the "Accounts") evidencing the Borrowings and other amounts owing by the Borrower to the Agent and each Lender under this Agreement.  The Agent shall debit therein the amount of such Borrowings, and shall enter therein each payment of principal of and interest on such Borrowings and fees and other amounts payable pursuant to this Agreement and shall record the Bankers' Acceptances accepted by each such Lender and the Letters of Credit issued by each such Lender and all other amounts becoming due to the Agent and each Lender under this Agreement.  The Accounts constitute, in the absence of manifest error, prima facie evidence of the indebtedness of the Borrower to the Agent and each Lender pursuant to this Agreement, the date each Lender made each Borrowing available to the Borrower and the amounts the Borrower has paid from time to time on account of the principal of and interest on the Borrowings, fees payable pursuant to this Agreement and other amounts owing hereunder. The Agent shall, from time to time upon the Borrower's reasonable request, provide to the Borrower copies of such accounts and records.

ARTICLE 5

5.1 Interest on Cdn. Prime Loans

The Borrower shall pay interest in Canadian Dollars to the Agent on behalf of each Lender on each Cdn. Prime Loan made by such Lender at the Agent's Account for Payments at a rate per three hundred sixty-five (365) day period equal to the Cdn. Prime Rate plus the Margin.  A change in the Cdn. Prime Rate or the Margin will simultaneously cause a corresponding change in the interest payable

for a Cdn. Prime Loan.  Such interest is payable monthly in arrears on the first Business Day following each Interest Date for the period commencing on and including the day after the immediately prior Interest Date up to and including such Interest Date or up to but excluding the Maturity Date and shall be calculated on a daily basis and on the basis of the actual number of days elapsed in a year of three hundred sixty-five (365) days.  The annual rates of interest to which the rates determined in accordance with the foregoing provisions of this Section 5.1 are equivalent are the rates so determined multiplied by the actual number of days in a period of one (1) year commencing on the first day of the period for which such interest is payable and divided by three hundred sixty-five (365).

5.2 Interest on U.S. Base Rate Loans

The Borrower shall pay interest in U.S. Dollars to the Agent on behalf of each Lender on each U.S. Base Rate Loan made by such Lender at the Agent's Account for Payments at a rate per three hundred sixty-five (365) day period equal to the U.S. Base Rate plus the Margin.  A change in the U.S. Base Rate or the Margin will simultaneously cause a corresponding change in the interest payable for a U.S. Base Rate Loan.  Such interest is payable monthly in arrears on the first Business Day following each Interest Date for the period commencing on and including the day after the immediately prior Interest Date up to and including such Interest Date or up to but excluding the Maturity Date and shall be calculated on a daily basis and on the basis of the actual number of days elapsed in a year of three hundred sixty-five (365) days.  The annual rates of interest to which the rates determined in accordance with the foregoing provisions of this Section 5.2 are equivalent are the rates so determined multiplied by the actual number of days in a period of one (1) year commencing on the first day of the period for which such interest is payable and divided by three hundred sixty-five (365).

5.3 Interest on Libor Loans

The Borrower shall pay interest in U.S. Dollars to the Agent on behalf of each Lender on each Libor Loan made by it at the Agent's Account for Payments for the period commencing on and including the first day of the Libor Interest Period applicable to such Libor Loan up to but not including the last day of such Libor Interest Period at a rate per three hundred sixty (360) day period equal to the sum of Libor plus the Margin.  A change in the Margin will simultaneously cause a corresponding change in the interest payable for a Libor Loan for the portion of the Libor Interest Period remaining at the time of the change in the Margin.  Such interest shall be payable on each Libor Interest Date applicable to such Libor Interest Period and shall be calculated on a daily basis and on the basis of the actual number of days elapsed in the period for which such interest is payable (including the first day of such period but excluding the date on which such interest is payable) divided by three hundred sixty (360).  The annual rates of interest to which the rates determined in accordance with the foregoing provisions of this Section 5.3 are equivalent are the rates so determined multiplied by the actual number of days in a period of one (1) year commencing on the first day of the period for which such interest is payable and divided by three hundred sixty (360).

54

manner specified in Section 3.6.  All fees payable pursuant to this Section 5.4 on any date in respect of any issuance of Bankers' Acceptances shall be calculated by the Agent and payable by the Borrower based on the Margin in effect on such date; provided that if during the term of any such Bankers' Acceptance a change in the  Margin occurs, the fees paid by the Borrower in respect of such Bankers' Acceptance shall be adjusted to reflect the  Margin for the remaining term of the Bankers' Acceptance and the Borrower, in the case of an increase in the  Margin, shall forthwith after receipt of a notice from the Agent make such payments to the Agent at the Agent's Account for Payments for the account of the Lenders as are necessary to reflect such change and the Lenders, in the case of a decrease in the Margin, shall credit any amount which would otherwise be refundable to the Borrower against amounts in respect of interest or fees accruing and next due hereunder.

Dollars or U.S. Dollars, as applicable, equal to the applicable Margin for each Letter of Credit issued hereunder for the period of time such Letter of Credit remains outstanding.  Such issue fee shall accrue and be calculated daily based on the Margin then in effect and the Lender's Proportion of such Lender of the face amount of each such Letter of Credit and on the basis of a year of three hundred sixty-five (365) days and shall be payable by the Borrower quarterly in arrears on the first Business Day of each calendar quarter for the immediately preceding calendar quarter.  A change in the Margin will simultaneously cause a corresponding change in the issue fee payable under any outstanding Letter of Credit.

(d) Credit on Account of Fees: If and to the extent that a Letter of Credit is drawn upon prior to the date of expiry thereof, or is terminated and returned to the Lenders or a Fronting Lender, as applicable, prior to such date of expiry, or the face amount thereof is reduced by the Lenders or a Fronting Lender, as applicable, prior to such date of expiry (other than through a drawing on such Letter of Credit) or any combination thereof, the Lenders and the Fronting Lenders, as applicable, shall forthwith after such event and through the Agent's Account for Payments credit the Borrower with any fees which it has paid in respect of any such Letter of Credit pursuant to Section 5.5(a) or 5.5(b) based upon the amount of the Letter of Credit on its termination or the amount of the reduction and for the time remaining in the period for which such fees were originally paid.

(a) if such amount is payable in Canadian Dollars, the interest rate applicable to Cdn. Prime Loans outstanding from time to time hereunder whether or not any Cdn. Prime Loans are then outstanding plus the Margin plus one percent (1%) per annum; and

Dollars on behalf of each Lender at the Agent's Account for Payments quarterly in arrears on the first Business Day of each calendar quarter in each year during the term of this Agreement commencing with the first Business Day of the calendar quarter occurring after the Effective Date.  Each payment of standby fees shall be calculated for the period commencing on and including the date hereof or the last date on which such standby fees were payable hereunder, as the case may be, up to and including the last day of the calendar quarter for which such standby fees are to be paid or the Maturity Date, as the case may be, and shall be in an amount equal to the Margin calculated on the amount, if any, of the difference obtained by subtracting the Borrowings outstanding from such Lender during such period from the amount of such Lender's Commitment in effect during such period.  Such standby fees shall be calculated on a daily basis and on the basis of the actual number of days elapsed in a year of three hundred sixty-five (365) days.  For purposes of calculating standby fees payable pursuant to this Section 5.7, the amount of Borrowings outstanding from time to time in U.S. Dollars on each day during the period for which such standby fees are payable shall be notionally converted to the Equivalent Amount in Cdn. Dollars at the rate of exchange in effect for purposes of determining an Equivalent Amount on such day.

5.9 Maximum Rate Permitted by Law

Under no circumstances shall a Lender be entitled to receive nor shall it in fact receive a payment or partial payment of interest, fees or other amounts under this Agreement at a rate that is prohibited by applicable law.  Accordingly, notwithstanding anything herein or elsewhere contained, if and to the extent that under any circumstances, the effective annual rate of "interest" (as defined in Section 347 of the Criminal Code of Canada) received or to be received by a Lender (determined in

56

accordance with such section) on any amount of "credit advanced" (as defined in that section) pursuant to these presents or any agreement or arrangement collateral hereto entered into in consequence or implementation hereof would, but for this Section 5.9, be a rate that is prohibited by applicable law, then the effective annual rate of interest, as so determined, received or to be received by such Lender on such amount of credit advanced shall be and be deemed to be adjusted to a rate that is one whole percentage point less than the lowest effective annual rate of interest that is so prohibited (the "adjusted rate"); and, if such Lender has received a payment or partial payment which would, but for this Section 5.9, be so prohibited then any amount or amounts so received by such Lender in excess of the adjusted rate shall and shall be deemed to have comprised a credit to be applied to subsequent payments on account of interest, fees or other amounts due to such Lender at the adjusted rate.

5.10 Waiver

To the extent permitted by law, any provision of the Judgment Interest Act (Alberta) and the Interest Act (Canada) which restricts the rate of interest on any judgment debt shall be inapplicable to this Agreement and is hereby waived by the Borrower.

All interest and fees payable hereunder which are to be adjusted as a result of a change in the Consolidated Senior Debt to EBITDA Ratio and a corresponding change in the Margin, shall be adjusted effective on the first day of the Fiscal Quarter following the Fiscal Quarter in which the Compliance Certificate is delivered (or which is due to be delivered) which indicates that a change in the Consolidated Senior Debt to EBITDA Ratio has occurred which requires a change to such interest and fees.

5.12 Nominal Rates

The theory of deemed reinvestment shall not apply to the calculation of interest or payment of fees or other amounts hereunder, notwithstanding anything contained in this Agreement, in any note, bankers' acceptance or other evidence of indebtedness or in any Loan Document now or hereafter taken by the Agent or any Lender for the obligations of the Borrower under this Agreement, or any other instrument referred to herein, and all other interest and fees payable by the Borrower to the Agent or any Lender, shall accrue from day to day, computed as described herein in accordance with the "nominal rate" method of interest calculation.

(a) firstly, in payment of any amounts due and payable as and by way of recoverable expenses hereunder;

(b) secondly, in payment of any amounts due and payable as and by way of the Agent's fees referred to in Section 5.8;

(e) fifthly, in payment of any amounts (other than Borrowings) then due and payable by the Borrower hereunder other than amounts hereinbefore referred to in this Section 6.2;

6.3 Taxes

The Borrower shall make all payments to the Agent on behalf of each Lender without set-off or counterclaim, free and clear of, and without deduction for or on account of, any Tax, except as contemplated in the next sentence.  If any Tax is deducted or withheld from any payments, other than any Tax withheld by reason of a Lender being a non-resident of Canada within the meaning of the Income Tax Act (Canada), the Borrower shall promptly remit to the Agent on behalf of the Lenders the equivalent of the amounts so deducted or withheld together with such additional amounts as may be necessary so that after making all required deductions or withholdings, including deductions or withholdings applicable to additional amounts paid under this Section 6.3, each Lender shall receive an amount equal to the amount it would have received if no deduction or withholding had been made, and the Borrower, if required by the Agent, shall also provide to the Agent the relevant official receipts or other evidence satisfactory to the Agent evidencing payment to the appropriate taxing authority of each such Tax by the Borrower on behalf of each Lender.

In the event the Borrower has made a payment pursuant to this Section 6.3 and any Lender is thereafter granted or receives a credit, refund or remission in respect of the Tax for which the deduction or withholding was made, then such Lender shall, subject to the Borrower having paid the relevant amount payable under this Section 6.3 and to the extent it is satisfied that it can do so without prejudice to the retention of the amount of such credit or refund, refund to the Borrower such amount (if any) as such Lender determines in good faith will leave such Lender in no worse position than would

58

have been the case if there had been no obligation to make such deduction or withholding in the first place.  No Lender shall be obligated to provide to the Borrower copies of all or any part of its tax returns, financial statements or other corporate financial data by reason of any such matter.

The Borrower authorizes and directs the Agent, in its discretion acting reasonably, to automatically debit, by mechanical, electronic or manual means, the bank accounts of the Borrower maintained with the Agent for all amounts due and payable under this Agreement, including, but not limited to, the repayment of principal and the payment of interest, fees and all charges for the keeping of such bank accounts.

but upon the occurrence of an Insolvency Event, the Total Commitment shall automatically terminate and all indebtedness and liabilities specified in Section 9.2(b) shall automatically become due and payable, in each case without any requirement that notice be given to the Borrower.  Immediately upon the occurrence of an Insolvency Event or at the time stated in an Acceleration Notice, the Borrower shall pay to the Agent on behalf of each Lender all amounts owing or payable in respect of such indebtedness and liabilities specified in Section 9.2(b), failing which all rights and remedies of the Lenders and the Agent under the Loan Documents shall thereupon become enforceable and shall be enforced by the Agent in accordance with the determinations of the Majority Lenders.

9.3 Waiver of Default

Any single or partial exercise by the Agent or any Lender of any right or remedy for a default or breach of any term, covenant, condition or agreement contained in the Loan Documents shall not be deemed to be a waiver of or to alter, affect or prejudice any other right or remedy to which the Agent or such Lender may be lawfully entitled for the same default or breach, and any waiver by the Agent or any Lender of the strict observance, performance or compliance with any term, covenant, condition or agreement contained in the Loan Documents, and any indulgence granted thereby, shall be deemed not to be a waiver of any subsequent default.  To the extent permitted by applicable law, the Borrower hereby waives any rights now or hereafter conferred by statute or otherwise which may limit or modify any of the Agent's or Lenders' rights or remedies under the Loan Documents.

(e) fifthly, rateably among the Lenders, the Operating Lender and the Swap Lenders in or towards repayment to the Lenders, the Operating Lender and the Swap Lenders of the Borrowings then outstanding, the Operating Borrowings then outstanding and the Swap Indebtedness then outstanding, subject to any adjustments required to be made in accordance with the provisions of Section 11.11; and

(f) any balance remaining to the Borrower or as otherwise required by applicable law.

9.5 Remedies Cumulative

For greater certainty, it is expressly understood and agreed that the rights and remedies of the Agent and the Lenders under the Loan Documents are cumulative and are in addition to and not in substitution for any rights or remedies provided by law. The Agent may on behalf of the Lenders and shall if so required by the Majority Lenders, to the extent permitted by applicable law, bring suit at law, in equity or otherwise for any available relief or purpose including but not limited to:

(a) the specific performance of any covenant or agreement contained in the Loan Documents;

(b) enjoining a violation of any of the terms of the Loan Documents;

In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, the Agent and each Lender are authorized at any time after the occurrence of an Event of Default which has not theretofore been waived or rescinded by the Lenders and from time to time thereafter without notice to the Borrower or to any other person, any such notice being expressly waived by the Borrower, to set-off and to appropriate and to apply any and all deposits (general and special) and any other indebtedness at any time held by or owing by the Agent or such Lender to or for the credit of or the account of the Borrower against and on account of the obligations and liabilities of the Borrower to the Agent or such Lender under this Agreement, including without limitation, all claims of any nature or description arising out of or connected with this Agreement, irrespective of whether such obligations, liabilities or claims of the Borrower are contingent or unmatured.

9.7 Cash Collateral Accounts

Upon the occurrence of an Event of Default or upon receipt of cash cover by the Agent pursuant to Sections 4.1, 4.2 or 4.5 and in addition to any other rights or remedies of the Lenders hereunder, the Agent, for the benefit of the Lenders hereunder, shall thereafter be entitled to deposit and retain in an account to be maintained by the Agent, and which for the purposes hereof shall be considered to be the Agent's account and not the Borrower's account (bearing interest for the Borrower's account at

72

the rates of the Agent as may be applicable in respect of other deposits of similar amounts for similar terms), amounts which are received by the Agent from the Borrower to the extent that and for so long as such amounts either may be required to satisfy any contingent or unmatured obligations or liabilities of the Borrower to the Agent and the Lenders under the Loan Documents or are actually used to satisfy any such obligations or liabilities; provided that if such amounts are no longer required or not so used, the Agent shall forthwith return the same to the Borrower.

9.8 Lenders May Perform Covenants

If the Borrower shall fail to perform any covenant on its part herein contained, the Agent may on behalf of the Lenders and with the approval of the Majority Lenders, upon five (5) Business Days prior notice to the Borrower, perform any of the said covenants capable of being performed by it and, if any such covenant requires the payment or expenditure of money, it may make such payment or expenditure with its own funds on behalf of the Lenders and shall be entitled to reimbursement of any such expenditure from each Lender based upon the proportion that such Lender's Commitment bears to the Total Commitment.  All amounts so paid by the Agent hereunder shall be repaid by the Borrower on demand therefor, and shall bear interest at the rate set forth in Section 5.6 from the date paid by the Agent hereunder to and including the date such amounts are repaid in full by the Borrower.

ARTICLE 10

EXPENSES AND INDEMNITIES

10.1 Reimbursement of Expenses and Indemnity

All statements, reports, certificates, opinions and other documents or information required to be furnished to the Agent or the Lenders by the Borrower under this Agreement shall be supplied by the Borrower without cost to the Agent or the Lenders.  In addition, the Borrower hereby agrees to pay promptly to the Agent on demand all reasonable legal fees and all other reasonable out of pocket expenses which are incurred from time to time by the Agent in respect of the documentation, preparation, negotiation, execution, and administration of the Loan Documents (including stamp taxes or other Taxes payable in connection with the execution, delivery or enforcement of the Loan Documents) and all expenses which are incurred from time to time by the Agent or the Lenders in respect of the enforcement of this Agreement and any other Loan Documents.

10.2 Increased Cost

If, subsequent to the date of this Agreement, the introduction of, any change in or the implementation of any applicable law, regulation, treaty or official directive or regulatory requirement of general application now or hereafter in effect (whether or not having the force of law) or any change in the interpretation or application thereof by any court or by any judicial or governmental authority charged with the interpretation or administration thereof, or if compliance by any Lender with any request from any central bank or other fiscal, monetary or other authority (whether or not having the force of law):

(a) subjects a Lender to any Tax, or changes the basis of taxation (through Taxes) of payments due to such Lender or increases any existing Tax, on payments of principal, interest or other amounts payable by the Borrower to such Lender under this Agreement;

(b) imposes, modifies or deems applicable any reserve, special deposit, capital adequacy, regulatory or similar requirement against assets or liabilities held by, or deposits in or for the account of, or

73

loans to, or any other acquisition of funds for loans or commitments to fund loans or obligations in respect of bankers' acceptances accepted by a Lender or letters of credit issued by a Lender; or

(c) imposes on a Lender any other condition with respect to this Agreement;

and the result of (a), (b), or (c) is, in the sole determination of such Lender acting reasonably and in good faith, to increase the cost to such Lender or to reduce the income or return which is receivable by such Lender in respect of a Borrowing or standby fees payable pursuant to Section 5.7, such Lender shall promptly notify the Agent.  The Agent shall promptly notify the Borrower and the Borrower shall pay to the Agent for the benefit of such Lender that amount which compensates such Lender for such additional cost or reduction in income ("Additional Compensation") on the next Libor Interest Date in the case of a Libor Loan, on the next date on which standby fees are payable under Section 5.7 in the case of standby fees and on the next Interest Date in any other case (and each such successive date, if and as applicable). The Borrower shall not be obligated to pay any portion of such Additional Compensation accruing under this Section 10.2 for any period prior to the date which is ninety (90) days prior to the date on which the Agent, on behalf of such Lender, gives notice to the Borrower that such Additional Compensation is so accruing.  A certificate by a duly authorized officer of such Lender prepared in good faith setting forth the amount of the Additional Compensation and the basis for it must be submitted by the Agent to the Borrower and is conclusive evidence, in the absence of manifest error, of the amount of the Additional Compensation.  Such Lender shall, for the purposes of the calculation of Additional Compensation and to the extent contractually permitted, treat the Borrower in a manner consistent with other borrowers of such Lender having credit facilities with such Lender comparable to the credit facilities hereunder.  If the Agent notifies the Borrower that Additional Compensation is owed, the Borrower shall pay such Additional Compensation to the Agent for the account of such Lender and the Borrower shall have the right, upon written irrevocable prior notice of at least three (3) Business Days to the Agent at the Agent's Branch of Account, to make payment in full to the Agent for the account of such Lender in respect of the applicable Borrowing on the date specified in such notice together with accrued interest in respect of such Borrowing or to convert such Borrowing into another basis of Borrowing available under this Agreement.

10.3 Illegality

If the introduction or application of or any change in applicable law, regulation, treaty or official directive, or regulatory requirement (whether or not having the force of law) or in the interpretation or application thereof by any court or by any governmental authority charged with the administration thereof, makes it unlawful, or prohibited for a Lender (in its good faith sole opinion) to make, to fund or to maintain the Borrowings or a portion of the Borrowings or to perform its obligations under this Agreement (including, in the case of a Fronting Lender, to issue Fronted Letters of Credit), such Lender may, by written notice to the Borrower through the Agent terminate its obligations under this Agreement or any portion thereof to make such Borrowings or perform such obligations and the Borrower shall prepay such Borrowings forthwith (or at the end of such period as is permitted under applicable law before the illegality or prohibition takes effect or as such Lender in its discretion otherwise agrees acting in good faith) together with all accrued but unpaid interest and fees as may be applicable to the date of payment or convert by notice to the Agent such Borrowings forthwith into another basis of Borrowing available under this Agreement.

10.4 Substitute Basis of Borrowing

(a) Libor Loans:  If, on or prior to any Interest Determination Date in respect of a Libor Loan, a Lender determines acting reasonably and in good faith (which determination is final, conclusive and binding upon the Borrower) that:

74

(i) adequate and fair means do not exist for ascertaining the rate of interest on such Libor Loan;

(ii) the cost to such Lender of making, funding or maintaining such Libor Loan does not accurately reflect the effective cost to such Lender thereof and the costs to such Lender are increased or the income receivable by such Lender is reduced in respect of such Libor Loan;

(iii) the making or the continuation of such Libor Loan or a portion of such Libor Loan by such Lender has become impracticable by reason of circumstances which materially and adversely affect the London interbank market; or

(iv) deposits in U.S. Dollars are not available to such Lender in the London interbank market in sufficient amounts in the ordinary course of business for the applicable Libor Interest Period to make, fund or maintain such Libor Loan during such Libor Interest Period;

then, such Lender shall promptly notify the Agent, and the Agent shall promptly notify the Borrower in writing of such determination setting forth the basis of such determination and such Lender shall not thereafter be obligated to provide such Libor Loan.  The Borrower shall thereupon forthwith notify the Agent as to the substitute basis of Borrowing available under this Agreement which it has selected for such Libor Loan.  If the Borrower has not so notified the Agent, such Libor Loan shall automatically be made as or converted to a U.S. Base Rate Loan on the date falling two (2) Business Days subsequent to such Interest Determination Date.

(b) Bankers' Acceptances:  In the event that at any time subsequent to the giving of a Drawdown Notice, Conversion Notice or Rollover Notice to the Agent by the Borrower with regard to any requested Bankers' Acceptances, but before the date of the Drawdown, Rollover or Conversion, as the case may be, the Agent (acting reasonably) makes a determination, which shall be conclusive and binding upon the Borrower, that there no longer exists an active market for bankers' acceptances accepted by the Lenders then:

(i) the right of the Borrower to request Bankers' Acceptances or BA Equivalent Advances from any Lender shall be suspended until the Agent determines that the circumstances causing such suspension no longer exist, and so notifies the Borrower;

(ii) any outstanding Drawdown Notice requesting an Accommodation by way of Bankers' Acceptances or BA Equivalent Advances shall be deemed to be a Drawdown Notice requesting an Accommodation by way of Cdn. Prime Loans in the amount specified in the original Drawdown Notice;

(iii) any outstanding Conversion Notice requesting a Conversion of U.S. Base Rate Loans or Libor Loans into Bankers' Acceptances or BA Equivalent Advances shall be deemed to be a Conversion Notice requesting a Conversion of such Loan into Cdn. Prime Loans; and

(iv) any outstanding Rollover Notice requesting a Rollover of Bankers' Acceptances or BA Equivalent Advances shall be deemed to be a Rollover Notice requesting a Conversion of such Bankers' Acceptances into Cdn. Prime Loans.

75

The Agent shall promptly notify the Borrower and the Lenders of any suspension of the Borrower's right to request Bankers' Acceptances or BA Equivalent Advances and of any termination of any such suspension.

10.5 Funding Indemnity

If, for any reason whatsoever and whether or not required or permitted pursuant to the provisions of this Agreement, the Borrower repays, prepays, converts or cancels a Libor Loan other than on the last day of a Libor Interest Period applicable to such Libor Loan, the Borrower shall indemnify the applicable Lender for any resulting loss or expense incurred by such Lender including, without limitation, any loss of profit or expenses such Lender incurs by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to maintain such Libor Loan or any increased interest or other charges payable to lenders of funds borrowed in order to maintain such Libor Loan together with any other out-of-pocket charges, costs or expenses incurred by such Lender relative thereto.  If, for any reason whatsoever and whether or not required or permitted pursuant to the provisions of this Agreement, the Agent or any Lender provides the Borrower with the anticipated discounted proceeds of sale of a Bankers' Acceptance (less any fees payable to such Lender in respect thereof) on any day prior to the receipt by the Agent or such Lender of such proceeds and the Agent or such Lender does not receive such proceeds from the person designated to purchase such Bankers' Acceptance on the date such proceeds are payable hereunder, the Borrower shall indemnify the Agent and each applicable Lender for any resulting loss, cost or expense incurred by the Agent or such Lender by reason of or arising as a result of the non-receipt or delayed receipt by the Agent or such Lender of such proceeds, including without limitation, any losses which the Agent or such Lender may incur if it arranges for any further sale of such Bankers' Acceptance in replacement thereof and any costs which the Agent or such Lender may incur in connection with any action against the person designated to purchase such Bankers' Acceptance, together with any other out-of-pocket charges, costs or expenses incurred by the Agent or such Lender relative thereto.  In each case, a certificate of the Agent or a certificate of such Lender (acting reasonably and prepared in good faith) setting out the basis for the determination of the amount necessary to indemnify such Lender shall be, in the absence of manifest error, conclusive evidence thereof.

10.6 General Indemnity

The Borrower hereby covenants with the Agent and each Lender that it shall at all times hereafter keep the Agent and such Lender indemnified and held harmless from and against all suits (whether founded or unfounded), actions, proceedings, judgments, demands or claims instituted or made against the Agent or such Lender, and all costs, losses, liabilities, damages and expenses (including all reasonable legal fees on a solicitor and his own client basis) incurred by the Agent or such Lender in any way relating to, arising out of, or incidental to (a) any provision of the Loan Documents, (b) any Environmental Laws applying to the Agent or such Lender as a result of it being a party to or performing its obligations under any Loan Document or (c) any default by the Borrower under any provision of any of the Loan Documents.  If and for so long as no Event of Default has occurred and is continuing, the Borrower, at its option, shall be entitled to conduct the defence of such suit, action or proceeding with the participation of the Agent or such Lender should they so desire.  If the defence of any such suit, action or proceeding is not being conducted in a proper or diligent manner by the Borrower, the Agent or such Lender shall on notice to the Borrower (and for the account of the Borrower) be entitled to take over the conduct of the defence of such suit, action or proceeding with the participation of the Borrower should it so desire.  This indemnity shall extend to the officers, directors, employees, agents, shareholders and assignees of the Agent and each Lender and shall survive the termination of this Agreement but shall not apply to any suits, actions, proceedings, judgments, demands or claims or costs, losses, liabilities,

76

damages and expenses resulting from or attributable to the willful misconduct or gross negligence of the Agent or any Lender or any officers, directors, employees, agents, shareholders or assignees thereof.

ARTICLE 11

THE AGENT AND THE LENDERS

11.1 Authorization of Agent

Each Lender irrevocably appoints and authorizes the Agent to exercise such powers, perform such duties, take such actions, make such decisions and determinations and give such consents under the Loan Documents as are required to be exercised, performed, taken, made, given or otherwise carried out by the Agent hereunder or under any other agreement between the Lenders, together with all powers reasonably incidental thereto.  As to any matters not expressly required by this Agreement or by any other agreement between the Lenders to be carried out by the Agent, the Agent is not required to exercise any discretion or take or to refrain from taking any action except upon the written instructions of the Majority Lenders.  Notwithstanding anything to the contrary in this Agreement, the Agent shall not be required to exercise any discretion or to take or to refrain from taking any action in any manner which is contrary to the Loan Documents, to any other agreement between the Lenders or to applicable law.

11.2 Responsibility of Agent

The Agent makes no representation or warranty and accepts no responsibility with respect to the due execution, legality, validity, sufficiency, enforceability or priority of any of the Loan Documents nor with respect to the due execution, legality, validity, sufficiency, enforceability, accuracy or authenticity of any documents, papers, materials or other information furnished by the Borrower (or any other person, including the Agent) in connection with the Loan Documents, whether provided before or after the date of this Agreement.  The Agent shall incur no liability to the Lenders under or in respect of the Loan Documents with respect to anything which it may do or refrain from doing in the reasonable exercise of its judgment or which may seem to it to be necessary or desirable in the circumstances, except for its gross negligence or willful misconduct.  The Agent assumes no responsibility for the payment of any of the Borrowings or other amounts outstanding hereunder or under the other Loan Documents by the Borrower or any other Loan Party.

11.3 Acknowledgment of Lenders

Each Lender acknowledges to the Agent that it has been, and will continue to be, solely responsible for making its own independent appraisal of and investigation into the financial condition, creditworthiness, affairs, status and nature of the Borrower and the other Loan Parties and accordingly each Lender confirms to the Agent that it has not relied, and will not hereafter rely on the Agent:

(a) Information:  to check or inquire on its behalf into the adequacy, accuracy or completeness of any information provided by the Borrower or in connection with the Loan Documents (whether or not such information has been or is hereafter circulated to such Lender by the Agent);

(b) Performance:  to inquire as to the performance by the Borrower or any other Loan Party of its obligations under the Loan Documents; or

(c) Credit Review:  to assess or keep under review on its behalf the financial condition, creditworthiness, affairs, status or nature of the Borrower or any other Loan Party.

77

11.4 Rights and Obligations of Each Lender

The rights and obligations of each Lender under this Agreement are several and no Lender shall be obligated to make Borrowings available to the Borrower in excess of its Commitment.  The failure of a Lender to perform its obligations under this Agreement shall neither:

(a) result in any other Lender incurring any liability whatsoever; nor

(b) relieve the Borrower or any other Lender from their respective obligations under any Loan Document.

Nothing contained herein or in any other Loan Document nor any action taken pursuant hereto or thereto shall be deemed to constitute the Lenders a partnership, joint venture or any other similar entity.

Each of the Lenders hereby acknowledges that, to the extent permitted by applicable law, the remedies provided hereunder to the Lenders are for the benefit of the Lenders collectively and acting together and not severally and further acknowledges that its rights hereunder are to be exercised not severally, but collectively by the Agent upon the decision of the Majority Lenders regardless of whether an Acceleration Notice has been delivered or an Insolvency Event has occurred.  Notwithstanding any of the provisions contained herein, each of the Lenders hereby covenants and agrees that it shall not be entitled to individually take any action with respect to the Loan Documents, including, without limitation, taking (including in respect of its Commitment or any indebtedness or liability owed to it) any action contemplated in Sections 9.2(a) and 9.2(b), but that any such action shall be taken only by the Agent with the prior written agreement or instructions of the Majority Lenders; provided that notwithstanding the foregoing if the Agent, having been adequately indemnified against costs and expenses of so doing by the Lenders, shall fail to carry out any such instructions of the Majority Lenders, any Lender may do so on behalf of all Lenders and shall, in so doing, be entitled to the benefit of all protections given the Agent hereunder or elsewhere.

11.5 Determinations by Lenders

(a) Lenders' Determinations:  Where the provisions of this Agreement provide that any waiver of or any amendment to any provision of the Loan Documents may be made or any action, consent or other determination in connection with the Loan Documents may be taken or given, with the consent or agreement of the Majority Lenders or "the Lenders" and not "all the Lenders", then any such waiver, amendment, action, consent or determination so made, so taken or so given with the consent or agreement of the Majority Lenders shall be binding on all of the Lenders and all of the Lenders shall cooperate in all ways necessary or desirable to implement and effect such waiver, amendment, action, consent or determination.

(b) Deemed Non-Consent:  If the Agent delivers a written notice to a Lender requesting advice from such Lender as to whether it consents or objects to any matter in connection with the Loan Documents, then, except as otherwise expressly provided herein, if such Lender does not deliver to the Agent its written consent or objection to such matter within fifteen (15) Business Days of the delivery of such written notice by the Agent to such Lender, such Lender shall be deemed not to have consented thereto upon the expiry of such fifteen (15)  Business Day period.

78

11.6 Notices between the Lenders, the Agent and the Borrower

All notices by the Lenders to the Agent shall be through the Agent's Branch of Account and all notices by the Agent to a Lender shall be through such Lender's Branch of Account.  All notices or communications between the Borrower and the Lenders which are required or contemplated pursuant to the Loan Documents shall be given or made through the Agent at the Agent's Branch of Account.

11.7 Agent's Duty to Deliver Documents Obtained from the Borrower

The Agent shall within five (5) Business Days deliver to each Lender, at such Lender's Branch of Account, such documents, papers, materials and other information as are furnished by the Borrower to the Agent on behalf of such Lender pursuant to this Agreement (the Agent's receipt of which is deemed, insofar as the Borrower and fulfillment of its obligations are concerned, to be receipt by all relevant Lenders notwithstanding the Agent's failure to perform its obligations under this Section 11.7), and the Borrower shall provide the Agent with sufficient copies of all such information for such purpose.  The Agent shall make requests of the Borrower pursuant to Section 8.1(o) from time to time on behalf of a Lender for such information as such Lender may from time to time reasonably request.

11.8 Arrangements for Borrowings

The Agent shall promptly give written notice to each Lender at its Branch of Account upon receipt by the Agent of any notice given pursuant to Section 3.4, 3.10, 3.12, 3.13, 4.3 or 4.4.  The Agent shall advise each Lender of the amount, date and details of each Accommodation and of such Lender's participation in each such Borrowing.  At or before 11:00 a.m. (Calgary time) on the Drawdown Date, Conversion Date or Rollover Date:

(a) Loan Participation:  each Lender will make its share of Accommodations by way of Loans available to the Borrower at the Agent's Account for Payments by forwarding to the Agent the amount of Loans required to be made available by such Lender;

(b) Bankers' Acceptance Participation: each Lender will make available to the Borrower its share of Accommodations by way of Bankers' Acceptances (or BA Equivalent Advances) by forwarding to the Agent at the Agent's Account for Payments the amount of:

(i) if such Lender is not a Purchasing Lender, the discounted proceeds of sale of such Bankers' Acceptances received by such Lender or the amount of any BA Equivalent Advance (less, in each case, the amount of applicable fees payable by the Borrower to such Lender pursuant to Section 5.4); or

(ii) if such Lender is a Purchasing Lender, the Discount Proceeds in respect of such Bankers' Acceptances and BA Equivalent Advances (less, in each case,  the amount of applicable fees payable by the Borrower to such Lender pursuant to Section 5.4); and

(c) Letter of Credit Participation:  each Lender and each Fronting Lender, as applicable, will make available to the Borrower the Letter of Credit requested by the Borrower at its Branch of Account.

79

11.9 Arrangements for Repayment of Borrowings

(a) Prior to Acceleration:  Prior to the delivery of an Acceleration Notice or the occurrence of an Insolvency Event, upon receipt by the Agent of payments from the Borrower on account of principal, interest, fees or any other amount paid to the Agent on behalf of the Lenders, the Agent shall pay over to each Lender at its Branch of Account the amount to which it is entitled under this Agreement and shall use its best efforts to make such payment to such Lender on the same Business Day on which such payment is received by the Agent.  If the Agent does not remit any such payment to a Lender on the same Business Day as such payment is received by the Agent, the Agent shall pay interest thereon to such Lender until the date of payment at a rate determined by the Agent (such rate to be conclusive and binding on such Lender) in accordance with the Agent's usual banking practice in respect of deposits of amounts comparable to the amount of such payment which are received by the Agent at a time similar to the time at which such payment is received by the Agent.

(b) Subsequent to Demand and Acceleration:  Following the delivery of an Acceleration Notice or the occurrence of an Insolvency Event, the Lenders shall share any payments subsequently received in accordance with Section 9.4 of this Agreement.

11.10 Repayment by Lenders to Agent

(a) Where Borrower Fails to Pay:  Unless the Agent has been notified in writing by the Borrower at least one (1) Business Day prior to the date on which any payment to be made by the Borrower hereunder is due that the Borrower does not intend to remit such payment, the Agent may, in its discretion, assume that the Borrower has remitted such payment when so due and the Agent may, in its discretion and in reliance upon such assumption, make available to each Lender on such payment date an amount equal to the amount of such payment which is due to such Lender pursuant to this Agreement.  If the Borrower does not in fact remit such payment to the Agent, the Agent shall promptly notify each Lender and each such Lender shall forthwith on demand repay to the Agent the amount of such assumed payment made available to such Lender, together with interest thereon until the date of repayment thereof at a rate determined by the Agent (such rate to be conclusive and binding on such Lender) in accordance with the Agent's usual banking practice for similar advances to financial institutions of like standing to such Lender.

(b) Where a Lender Fails to Pay:  Unless the Agent has been notified in writing by a Lender at least one (1) Business Day prior to a Drawdown Date, Conversion Date or Rollover Date that such Lender does not intend to make available the amount required to be made available by such Lender pursuant to this Agreement on such Drawdown Date, Conversion Date or Rollover Date, the Agent may, in its discretion, assume that such Lender has remitted funds to the Agent in an amount equal to the amount required to be made available by such Lender pursuant to this Agreement and the Agent may, in its discretion and in reliance upon such assumption, make available to the Borrower on such Drawdown Date, Conversion Date or Rollover Date an amount equal to the amount required to be made available by such Lender pursuant to this Agreement.  If such Lender does not in fact remit such funds to the Agent, the Agent shall promptly notify such Lender and such Lender shall forthwith remit such funds to the Agent, failing which:

(i) the Borrower shall on two (2) Business Days notice repay to the Agent (without prejudice to the Borrower's rights against such Lender) the amount made available by the Agent on behalf of such Lender, in each case together with interest thereon until the date of repayment thereof at a rate determined by the Agent (such rate to be conclusive and

80

binding on such Lender or the Borrower, as the case may be) in accordance with the Agent's usual banking practice for similar advances to financial institutions of like standing to such Lender; and

(ii) without prejudice to the Borrower's other rights against such Lender, Section 4.4(f)(i) or 4.4(f)(ii) shall, at the Borrower's election, apply in regard to such Lender, mutatis mutandis, as if such Lender were an Affected Lender.

11.11 Adjustments Among Lenders

(a) Adjustments to Outstanding Borrowings:  Each Lender agrees (and the Agent agrees for and on behalf of Royal in its capacity as Operating Lender) that, after the delivery of an Acceleration Notice or the occurrence of an Insolvency Event, it will at any time and from time to time upon the request of the Agent as required by any Lender or the Operating Lender purchase portions of the Term Indebtedness or Operating Indebtedness of such other Lenders, as applicable, which in any case, remain outstanding and make any other adjustments which may be necessary or appropriate, in order that the amount of Term Indebtedness of each Lender which remains outstanding, and the Operating Indebtedness which remains outstanding, as adjusted pursuant to this Section  11.11, will be in the same proportion as its Lender's Proportion (calculated pursuant to item (b) of the definition thereof) of the sum of the aggregate Term Indebtedness under this Agreement and the Operating Indebtedness then outstanding.

(b) Application of Payments:  The Lenders agree that, after the delivery of an Acceleration Notice or the occurrence of an Insolvency Event, the amount of any repayment made by any Loan Party in respect of Term Indebtedness under this Agreement, Operating Indebtedness under the Operating Credit Agreement or Swap Indebtedness under any Swap Agreement with a Swap Lender, and the amount of any proceeds from the exercise of any rights or remedies of the Agent, the Lenders, the Operating Lender and the Swap Lenders under the Loan Documents, under the Operating Loan Documents or under a Swap Agreement, which are to be applied against amounts owing hereunder, will be applied in accordance with Section 9.4.

(c) Receipt of Payments other than Borrowings:  Notwithstanding anything contained in this Section 11.11, there shall not be taken into account for the purposes of computing any amount payable to a Lender, Operating Lender or Swap Lender pursuant to this Section 11.11, any amount which such Lender receives as a result of any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of any monies owing by a Loan Party to such Lender other than on account of Term Indebtedness, Operating Indebtedness or Swap Indebtedness; provided that, if at any time a Lender, Operating Lender or Swap Lender receives any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of monies owing or payable to it by a Loan Party in respect of liabilities of a Loan Party under Term Indebtedness, Operating Indebtedness or Swap Indebtedness, such payments will be applied in accordance with Section 9.4; provided further that the provisions of this Section 11.11(c) shall not apply to a Swap Lender which sets off amounts owing by a Loan Party to such Swap Lender under a Swap Agreement against amounts owing by such Swap Lender (including, for clarity, its Affiliates) to a Loan Party under any Swap Agreement entered into between such parties.  To the extent that a Swap Agreement is entered into by an Affiliate of a Lender or the Operating Lender, that Lender or the Operating Lender, as the case may be, shall cause such Affiliate to comply with the provisions of Section 9.4 and this Section 11.11, and such obligation shall survive such Lender (at any time after any such Swap

81

Agreement was entered into) ceasing to be a Lender hereunder or the Operating Lender ceasing to be the Operating Lender hereunder, as the case may be.

(d) Further Assurances:  The Borrower agrees to be bound by and, at the request of the Agent, to do all things necessary or appropriate to give effect to any and all purchases and other adjustments made by and between the Lenders pursuant to this Section 11.11 but shall incur no increased liabilities, in aggregate, by reason thereof.

11.12 Lenders' Consents to Waivers, Amendments, etc.

(a) Unanimous Consent:  Any waiver of or any amendment to a provision of the Loan Documents which relates to:

(i) a change in the types of Borrowings or interest periods related thereto, interest rates, standby fees, the Margin, notice periods or the amount of any payments payable by the Borrower to the Lenders under this Agreement and including any waiver of the time of payment of any amounts payable to the Lenders under this Agreement including, without limitation, the provisions of Section 9.1(a);

(ii) an increase or decrease in the Commitment of any Lender other than as contemplated herein;

(iii) an assignment or transfer by the Borrower of any of its rights and obligations under this Agreement;

(iv) a change in the definition of Majority Lenders or  Maturity Date or any other definition to the extent relevant to any of the provisions of this Section 11.12(a);

(v) any matter which, pursuant to the Loan Documents, specifically requires the consent or agreement of all of the Lenders;

(vi) the provisions of Section 8.1(q), 11.12(a) or 11.12(b); or

(vii) any release or material amendment to the Loan Party Guarantee;

shall bind the Lenders only if such waiver or amendment is agreed to in writing by all of the Lenders.

(b) Majority Consent:  Subject to Section 11.12(a) and except as otherwise provided in the Loan Documents, any waiver of or any amendment to any provision of the Loan Documents and any action, consent or other determination in connection with the Loan Documents shall bind all of the Lenders if such waiver, amendment, action, consent or other determination is agreed to in writing by the Majority Lenders.

(c) Agent's Consent:  Any waiver of or any amendment to any provision of the Loan Documents which relates to the rights or obligations of the Agent shall require the agreement of the Agent thereto.

11.14 Reliance by Agent and Lenders on Notices, etc.

(a) Agent's Reliance:  The Agent shall be entitled:

(i) Reliance on Written Documents:  to rely upon any writing, letter, notice, certificate, telex, facsimile copy, cable, statement, order or other document believed by the Agent to be genuine and correct and to have been signed, sent or made by the proper person or persons;

(ii) Reliance on Legal Advice:  with respect to legal matters, to act upon the advice of legal advisors selected by the Agent concerning all matters pertaining to the Loan Documents and the Agent's duties thereunder; and

(iii) Reliance on Accounting Advice: with respect to accounting matters, to act upon the advice of independent public accountants selected by the Agent;

and the Agent shall assume no responsibility and shall incur no liability to the Borrower or any Lender by reason of relying on any such document or acting on any such advice.

(b) Lender's Reliance:  Each Lender shall be entitled:

(i) Reliance on Written Documents:  to rely upon any writing, letter, notice, certificate, telex, facsimile copy, cable, statement, order or other document believed by such Lender to be genuine and correct and to have been signed, sent or made by the proper person or persons;

(ii) Reliance on Legal Advice:  with respect to legal matters, to act upon the advice of legal advisors selected by such Lender concerning all matters pertaining to the Loan Documents and such Lender's duties thereunder; and

(iii) Reliance on Accounting Advice: with respect to accounting matters, to act upon the advice of independent public accountants selected by such Lender;

and such Lender shall assume no responsibility and shall incur no liability to the Borrower or any other Lender by reason of relying on any such document or acting on any such advice.

11.15 Relations with Borrower

Except for the transactions provided for in this Agreement, each Lender may deal with the Borrower and each other Loan Party in all transactions and generally do any banking business with or

83

provide any financial services to the Borrower and each other Loan Party without having any liability to account to the other Lenders therefor.  Where any Lender is the Agent, with respect to such Lender's Commitment and Lender's Proportion, such Lender shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Agent.

11.16 Sharing of Information

The Borrower authorizes the Agent and each Lender to share among each other and with any successor and, provided such person has first agreed in writing in favour of the Borrower and the relevant Lender to be bound by this Section 11.16, with any assignee, or any potential assignee, any information possessed by it regarding the Borrower, any other Loan Party or the Loan Documents.  The Agent and each Lender agree to keep all information provided by the Borrower confidential in accordance with Section 12.3 and, subject to Section 12.3, shall not disclose such information to any person whatsoever (other than as provided for herein and other than to employees and professional advisors to the Agent or such Lender (but excluding therefrom any affiliate of such Lender which is not in the commercial banking business) in the necessary course of business).

11.17 Successor Agent

Subject to the appointment and acceptance of a successor agent as provided in this Section 11.17, the Agent may resign at any time by giving written notice thereof to each of the Lenders and the Borrower, and the Agent may be removed at any time for cause by the Lenders other than the Agent in its capacity as a Lender (the "Remaining Lenders") provided that Remaining Lenders holding Commitments of eighty percent (80%) or more of the Commitments of all the Remaining Lenders consent to such removal.  Upon any such resignation or removal, the Remaining Lenders shall have the right to appoint a successor agent with the written approval of the Borrower (such approval not to be unreasonably withheld).  Any successor agent appointed under this Section 11.17 shall be a Lender which has offices in Calgary, Alberta and Toronto, Ontario.  If no successor agent shall have been appointed by the Remaining Lenders and shall have accepted such appointment within thirty (30) days after the retiring agent's giving of notice of resignation or the Remaining Lenders' removal of the retiring agent, then the retiring agent may, on behalf of the Lenders and with the written approval of the Borrower (such approval not to be unreasonably withheld), appoint a successor agent.  Upon the acceptance of any appointment as Agent by a successor agent such successor agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring agent as Agent, and the retiring agent shall be discharged from its duties and obligations under this Agreement as Agent.  After any retiring agent's resignation or removal hereunder as the Agent, the provisions of this Agreement shall continue in effect for its benefit and for the benefit of the Lenders in respect of any actions taken or omitted to be taken by the retiring agent while it was acting as the Agent.

11.18 Amendment of this Article 11

Save and except for the provisions of Section 11.11, Section 11.15, Section 11.17 and this Section 11.18, the provisions of this Article 11 may be amended or added to, from time to time, without the agreement of the Borrower provided such amendment or addition does not adversely affect the rights of the Borrower hereunder or increase, in aggregate, the costs or liabilities of the Borrower hereunder or otherwise prejudice the Borrower.  A copy of the instrument evidencing such amendment or addition shall be forwarded by the Agent to the Borrower as soon as practicable following the execution thereof.

84

11.19 Dealing with Agent

In the absence of notice or any actual knowledge of a lack of authority of the Agent to act for and on behalf of the Lenders in respect of any matter hereunder or under the Loan Documents, the Borrower shall be entitled to conclusively assume that any certificate, directive or other writing of the Agent for and on behalf of the Lenders in connection with such matter has been duly authorized by the Lenders in accordance with this Agreement.

11.20 Indemnity of Agent

Each Lender hereby agrees to indemnify the Agent (to the extent not reimbursed by the Borrower), as to its Lender's Proportion from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Agent in any way relating to or arising out of this Agreement or the other Loan Documents or any action taken or omitted by the Agent under or in respect of this Agreement or the other Loan Documents provided that the Lenders shall not be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Agent's gross negligence or willful misconduct.  Without limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its Lender's Proportion of any out-of-pocket expenses (including counsel fees) incurred by the Agent in connection with the preservation of any rights of the Agent or the Lenders under, or the enforcement of, or legal advice in respect of rights or responsibilities under, this Agreement and the other Loan Documents, to the extent that the Agent is not reimbursed for such expenses by the Borrower.

11.21 Authority of Agent to Execute Intercreditor Agreements

Each Lender hereby irrevocably appoints and authorizes the Agent to execute and deliver, for and on behalf of the Lenders and each of their Affiliates who are Swap Lenders from time to time, such intercreditor agreements, acknowledgements and other documents as the Agent may deem acceptable to confirm the pari passu ranking of the Term Indebtedness and the Swap Indebtedness with Debt of any Loan Party under any issuances of senior unsecured notes or similar obligations by a Loan Party or any guarantees thereof.

11.22 The Agent, Fronting Lenders and Defaulting Lenders

(a) Provision of Cash to Agent:  Each Defaulting Lender shall be required to provide to the Agent cash in an amount, as shall be determined from time to time by the Agent or any Fronting Lender, as the case may be, in its discretion, equal to all obligations of such Defaulting Lender to the Agent or such Fronting Lender, as the case may be, that are owing or may become owing pursuant to this Agreement, including such Defaulting Lender's obligation to pay its Lender's Proportion of any indemnification, reimbursement or expense reimbursement amounts not paid by the Borrower.  Such cash shall be held by the Agent in one or more cash collateral accounts, which accounts shall be in the name of the Agent and shall not be required to be interest bearing.  The Agent shall be entitled to apply the foregoing cash in accordance with Section 11.9, in the case of amounts owing to the Agent, or to pay the amounts owing to such Fronting Lender from the Defaulting Lender, in the case of amounts owing to such Fronting Lender pursuant hereto (including pursuant to Section 5.5).

(b) Lenders to Indemnify Agent:  In addition to the indemnity and reimbursement obligations noted in Section 11.20, the Lenders agree to indemnify the Agent (to the extent not reimbursed by the

85

Borrower and without limiting the obligations of the Borrower hereunder) rateably according to their respective Lender's Proportions (and in calculating the Lender's Proportion of a Lender, ignoring the Commitments of Defaulting Lenders) any amount that a Defaulting Lender fails to pay the Agent and which is due and owing to the Agent pursuant to Section 11.20.  Each Defaulting Lender agrees to indemnify each other Lender for any amounts paid by such Lender and which would otherwise be payable by the Defaulting Lender.

(c) Set Off:The Agent shall be entitled to set off any Defaulting Lender's Proportion of all payments received from the Borrower against such Defaulting Lender's obligations to make payments and fund Accommodations required to be made by it and to purchase participations required to be purchased by it in each case under this Agreement and the other Loan Documents.  To the extent permitted by law, the Agent shall be entitled to withhold and deposit in one or more non-interest bearing cash collateral accounts in the name of the Agent all amounts (whether principal, interest, fees or otherwise) received by the Agent and due to a Defaulting Lender pursuant to this Agreement, for so long as such Lender is a Defaulting Lender, which amounts shall be used by the Agent:

(i) first, to reimburse the Agent for any amounts owing to it, in its capacity as Agent, by such Defaulting Lender pursuant to any Loan Document and to reimburse the Lenders for any amounts paid by the Lenders to the Agent under Section 11.22(b) rateably according to their respective Lenders' Proportion;

(ii) second, to the payment of any amounts owing by such Defaulting Lender to the Fronting Lenders hereunder;

(iii) third, to repay on a pro rata basis the incremental portion of any Accommodations made by a Lender pursuant to Section 12.4 in order to fund a shortfall created by a Defaulting Lender and, upon receipt of such repayment, each such Lender shall be deemed to have assigned to the Defaulting Lender such incremental portion of such Accommodations;

(iv) fourth, to cash collateralize all other obligations of such Defaulting Lender to the Agent or the Fronting Lenders owing pursuant to this Agreement in such amount as shall be determined from time to time by the Agent in its discretion, including such Defaulting Lender's obligation to pay its Lender's Proportion of any indemnification, reimbursement or expense reimbursement amounts not paid by the Borrower; and

(v) fifth, to fund from time to time the Defaulting Lender's Lender's Proportion of Applicable Borrowings.

(d) No Liability:  For greater certainty and in addition to the foregoing, neither the Agent nor any of its Affiliates nor any of their respective shareholders, officers, directors, employees, agents or representatives shall be liable to any Lender (including a Defaulting Lender) for any action taken or omitted to be taken by it in connection with amounts payable by the Borrower to a Defaulting Lender and received and deposited by the Agent in a cash collateral account and applied in accordance with the provisions of this Agreement, save and except for the gross negligence or wilful misconduct of the Agent as determined by a final non-appealable judgement of a court of competent jurisdiction.

(e) Fronted Letters of Credit:  Notwithstanding any other provision hereof to the contrary, so long as any Lender is a Defaulting Lender, no Fronting Lender shall be obligated to issue any Fronted

86

Letter of Credit unless and until the applicable Fronting Lender (or the Agent on its behalf) has been provided with cash collateral to fully collateralize the applicable Fronting Lender's exposure to each such Defaulting Lender on terms and conditions satisfactory to the applicable Fronting Lender in its discretion, acting reasonably.

Subject to Section 8.2(b), the Borrower may not assign its rights or obligations hereunder without the prior written consent of all of the Lenders.  If an Event of Default has occurred and is continuing, a Lender may, at the Borrower's cost and expense, with the prior consent of the Agent (such consent not to be unreasonably withheld) and upon payment by such Lender to the Agent of Cdn. $3,500 but without the Borrower's consent, assign in whole or in part its rights and obligations under this Agreement and the other Loan Documents.  If no Event of Default has occurred or is continuing, a Lender may, at its sole cost and expense, with the prior consent of the Agent and the Borrower (such consents not to be unreasonably withheld) and upon payment by such Lender to the Agent of Cdn. $3,500 (where the Permitted Assignee is not a Lender or, if a Lender, such assignment is not made pursuant to or in the course of, a Request for Extension), assign in whole or in part its rights and obligations under this Agreement and the other Loan Documents where such Lender assigns minimum amounts of its Commitment of at least Cdn. $10,000,000 and, to the extent it is not an assignment of the whole of its Commitment, such Lender would thereafter retain for its own account a Commitment of at least Cdn. $10,000,000.  Notwithstanding the foregoing and without the consent of the Borrower or the Agent or the payment of the aforementioned fee of Cdn. $3,500, a Lender may, at any time, assign all or any part of its Commitment to an affiliate of such Lender or an Approved Fund provided that any increased cost arising solely as a result of the residency of such affiliate or Approved Fund will be an obligation of such Lender and provided that, in the case of an assignment to an Approved Fund, such Lender remains responsible for, and is not released from, any and all funding obligations hereunder of such Lender.  Upon any assignment by a Lender to an assignee permitted by this Section 12.1 (a "Permitted Assignee") in accordance with the provisions of this Section 12.1, such Lender shall cause such Permitted Assignee to execute a Lender Transfer Agreement and to be substituted for such Lender in respect of the whole or any part of its rights and obligations under the Loan Documents which are so assigned and such Lender shall, as of the effective date thereof but subject to the provisions of the immediately prior sentence with respect to an assignment to an Approved Fund, be released from its obligations to the Borrower hereunder arising subsequent to such date to the extent thereof.  Any such assignment shall not increase, in aggregate, the liabilities of the Borrower hereunder (including, without limitation, under Section 6.3), other than the requirement to pay any costs and expenses associated with an assignment by the Borrower or by a Lender if an Event of Default has occurred and is continuing.  Nothing in this Section 12.1 shall restrict a Lender from the sale of participations in all or any part of the Borrowings made or to be made by it; provided that any increased costs to the Borrower as a result of any such participation shall be for the account of such Lender.  The selling Lender shall continue to be obligated as a Lender hereunder and the participant's approval to any amendments or waivers under this Agreement shall not be required notwithstanding any such participation.  A person who acquires a participation in Borrowings hereunder shall have no standing as a Lender under the Loan Documents and shall not acquire as a result thereof any rights or benefits under any of the Loan Documents in relation to the Borrower.

12.2 Judgment Currency

If for the purposes of obtaining judgment in any court in any jurisdiction with respect to this Agreement it becomes necessary to convert into the currency of such jurisdiction (herein called the "Judgment Currency") any amount due hereunder in any currency other than the Judgment Currency, then conversion shall be made at the rate of exchange prevailing on the Business Day before the day on which judgment is given.  For this purpose "rate of exchange" means the spot rate at which the Agent will, on the relevant date at or about 12:00 o'clock noon (Toronto time), sell such currency in Toronto, Ontario against the Judgment Currency.  In the event that there is a change in the rate of exchange prevailing between the Business Day before the day on which the judgment is given and the date of payment of the amount due, the Borrower will, on the date of payment, pay such additional amounts (if any) as may be necessary to ensure that the amount paid on such date is the amount in the Judgment Currency which when converted at the rate of exchange prevailing on the date of payment is the amount then due under this Agreement in such other currency.  Any additional amount due from the Borrower under this Section 12.2 will be due as a separate debt and shall not be affected by judgment being obtained for any other sums due under or in respect of this Agreement.

12.3 Exchange and Confidentiality of Information

Each of the Lenders and the Agent acknowledge the confidential nature of the financial, environmental, operational and other information, reports and data provided and to be provided to them by the Borrower pursuant to this Agreement and the other Loan Documents including, without limitation, any confidential information obtained pursuant to Section 8.1(o) and Section 13.7 (the "Information") and agrees to hold the Information in confidence and shall not discuss or disclose or allow access to, or transfer or transmit the Information to any person, provided however that:

(a) each of the Lenders, the Swap Lenders and the Agent may disclose all or any part of the Information if, in its reasonable opinion, such disclosure is required by any applicable law or regulation, or by applicable order, policy or directive having the force of law, to the extent of such requirement, or is required in connection with any actual or threatened judicial, administrative or governmental proceeding, including, without limitation, proceedings initiated under or in respect of this Agreement, provided that in any such circumstance the Lenders and Agent, as soon as reasonably practicable, shall advise the Borrower of their obligation to disclose such Information in order to enable the Borrower, if it so chooses, to attempt to ensure that any such disclosure is made on a confidential basis;

(b) each of the Lenders and the Agent may disclose Information to each other and to any Permitted Assignees or participants and to their respective counsel, agents, employees and advisors; provided that in the case of a participant, the participant has provided the Agent or the applicable Lender with the written agreement referred to in Section 12.3(c) and, in the case of any such agents and advisors, the Agent or the applicable Lender shall advise such person of the confidential nature of the Information;

(c) each of the Lenders and the Agent may disclose and discuss the Information with credit officers of any potential Permitted Assignees for the purposes of assignment pursuant to Section 12.1 or any participant for the purposes of a participation; provided that such potential Permitted Assignee or participant shall have, for the benefit of the Borrower, previously provided to the Agent or such Lender, as the case may be, its written agreement to hold the Information under the same obligations of confidentiality as set forth in this Section 12.3 at all times prior to and, if applicable, after becoming a Permitted Assignee or participant;

88

(d) each of the Lenders may disclose Information to any actual or prospective counterparty (or its advisors) to any securitization, swap or derivative transaction relating to the Borrower or the obligations hereunder, provided the counterparty has provided the applicable Lender with the written agreement referred to in Section 12.3(c);

(e) each of the Lenders and the Agent may disclose all or any part of the Information so as to enable such Lender or the Agent to initiate any lawsuit against the Borrower or any other Loan Party or to defend any lawsuit commenced by the Borrower or any other Loan Party with respect to or arising from the Loan Documents, the issues of which are directly or indirectly related to the Information, but only to the extent such disclosure is necessary or desirable to the initiation or defense of such lawsuit; and

(f) each of the Lenders and the Agent may disclose Information to any person with the prior written consent of the Borrower.

Notwithstanding the foregoing, "Information" shall not include any such information:

(g) which is or becomes readily available to the public (other than by a breach hereof or by a breach of an obligation of confidentiality imposed on a Permitted Assignee or participant or other person referred to in this Section 12.3) or which has been made readily available to the public by the Borrower or any other Loan Party;

(h) which the Agent or any Lender can show was, prior to receipt thereof from the Borrower, lawfully in the Agent's or such Lender's possession and not then subject to any obligation on its part to or for the benefit of the Borrower to maintain confidentiality; or

(i) which the Agent or any Lender received from a third party, prior to receipt thereof from the Borrower,  which was not, to the knowledge of the Agent or such Lender after due enquiry, subject to a duty of confidentiality to or for the benefit of the Borrower at the time the Information was so received.

12.4 Defaulting Lenders

(a) Impact on Standby Fees and Votes:  Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(i) the standby fees payable pursuant to Section 5.5 shall cease to accrue on the unused portion of the Commitment of such Defaulting Lender;

(ii) a Defaulting Lender shall not be included in determining whether, and the Commitment and the Lender's Proportion of the Borrowings of such Defaulting Lender shall not be included in determining whether, all Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 11.12), provided that any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that: (A) materially and adversely affects such Defaulting Lender differently than other affected Lenders; (B) changes the Commitment or extends the Maturity Date of such Defaulting Lender; (C) relates to the release or discharge to the Loan Party Guarantee; or (D) waives or forgives payment of

89

any Borrowings owing to such Defaulting Lender, shall require the consent of such Defaulting Lender; and

(iii) for the avoidance of doubt, the Borrower shall retain and reserve its other rights and remedies respecting each Defaulting Lender.

(b) Funding:  If the Agent has actual knowledge that a Lender is a Defaulting Lender at the time that the Agent receives: (i) a notice of Borrowing; or (ii) a Conversion Notice that will result in a currency conversion, then each other Lender shall fund its Lender's Proportion of such affected Accommodation (and, in calculating such Lender's Proportion, the Agent shall ignore the Commitments of each such Defaulting Lender); provided that, for certainty, no Lender shall be obligated by this Section 12.4(b) to make or provide Accommodations in excess of its Commitment.  If the Agent acquires actual knowledge that a Lender is a Defaulting Lender at any time after the Agent received: (i) a notice of Borrowing; or (ii) a Conversion Notice that will result in a currency conversion, then the Agent shall promptly notify the Borrower that such Lender is a Defaulting Lender (and such Lender shall be deemed to have consented to such disclosure).  Each Defaulting Lender agrees to indemnify each other Lender for any amounts paid by such Lender under this Section 12.4(b) and which would otherwise have been paid by the Defaulting Lender if its Commitment had been included in determining the Lender's Proportion of such affected Accommodations.

(c) Ceasing to be Defaulting Lender:  If any Lender shall cease to be a Defaulting Lender, then, upon becoming aware of the same, the Agent shall notify the other Lenders and (in accordance with the written direction of the Agent) such Lender (which has ceased to be a Defaulting Lender) shall purchase, and the other Lenders shall on a rateable basis sell and assign to such Lender, portions of such Borrowings equal in total to such Lender's Lender's Proportion thereof without regard to Section 12.4(b).
