ARTICLE 3
THE CREDIT FACILITY

3.1 Obligations of Each Lender

Relying on each of the representations and warranties set out in Article 2 and subject to the terms and conditions of this Agreement, each Lender agrees to make Accommodations available to the

Borrower up to the amount of its Commitment, in each case commencing on the Effective Date and ending on the Maturity Date applicable to such Lender or sooner as herein provided, by way of:

(a)

the advance of Loans by each such Lender;

(b)

either:

(i): the acceptance of Bankers' Acceptances or the making of a BA Equivalent Advance by such Lender and the delivery of the discounted proceeds of sale received by such Lender or the amount of BA Equivalent Advance (less the applicable Acceptance Fees payable by the Borrower to such Lender) in respect thereof for the account of the Borrower through the Agent at the Agent's Account for Payments; or
(ii): the purchase of Bankers' Acceptances or the making of a BA Equivalent Advance by such Lender and the delivery of the Discount Proceeds in respect of such Bankers' Acceptances or BA Equivalent Advance (less the applicable Acceptance Fees payable by the Borrower to such Lender) for the account of the Borrower through the Agent at the Agent's Account for Payments; and

(c)

the issuance of Letters of Credit by the Agent or the Fronting Lenders for and on behalf of the Lenders through the Agent at the Agent's Branch of Account.

The Credit Facility is a revolving credit facility and prior to the Term Date of each Lender, the Borrower may increase or decrease Borrowings from each such Lender by obtaining Loans or Bankers' Acceptances and BA Equivalent Advances, as applicable, or Letters of Credit, and by making repayments in respect thereof. From and after the Term Date of each Lender, the credit facility represented by the Commitment of such Lender shall cease to be a revolving credit facility and shall be converted into a non-revolving term credit facility and the Borrower may effect Conversions and Rollovers thereunder as provided for herein but may not obtain further advances or increase Borrowings from such Lender during the Term Period of such Lender.

A Lender shall not have any obligation to make any Loans or accept Bankers' Acceptances or make BA Equivalent Advances or become liable under a Letter of Credit at any time if, after giving effect thereto, the Equivalent Amount in Canadian Dollars of Borrowings from such Lender would exceed the Commitment of such Lender.

3.2 Re-Allocation

The Borrower shall be entitled from time to time to cancel all or any portion of the unutilized Commitment of each Exempt Lender (a "Switching Exempt Lender" and collectively, the "Switching Exempt Lenders") in respect of whom the Term Period has not yet commenced (collectively, the "Cancelled Canadian Commitment") provided that concurrently therewith the Borrower increases the "Total Commitment" and the "Commitment" of such Switching Exempt Lenders under the International Credit Facility by an equal amount. In order to give effect to any such cancellation, the Borrower shall deliver a Reallocation Request to each of the Agent and the "Agent" under the International Credit Facility provided that:

(a): the Reallocation Request shall be given at least ten (10) Business Days prior to it becoming effective;
(b): at the time the Reallocation Request becomes effective, no Default or Event of Default has occurred and is continuing and no "Default" or "Event of Default" has occurred and is continuing under the International Credit Facility;
(c): the Cancelled Canadian Commitment shall be in a minimum amount of Cdn. $50,000,000 and shall be made on a pro-rata basis among the Switching Exempt Lenders based upon the Pro-Rata Share of each such Switching Exempt Lender and the aggregate of the Commitments of such Switching Exempt Lenders;

(d): the Agent and the Lenders shall take all such steps as are reasonably necessary to ensure that after giving effect to any such cancellation Borrowings are outstanding on a Pro-Rata Share based on the revised Total Commitment and Commitment of each Switching Exempt Lender as soon as reasonably possible given the nature of the Borrowings then outstanding and, until such time, the Lenders acknowledge and agree that Borrowings will not be outstanding on the basis of the Pro-Rata Shares after giving effect to such cancellation; and
(e): a Reallocation Request shall not be given more than two (2) times in any calendar year.

The Agent and the Lenders acknowledge that under the International Credit Facility the Borrower has the same rights it has hereunder to provide the "Agent" thereunder and the Agent with a "Reallocation Request" whereby the Commitment of the Exempt Lenders hereunder in respect of whom the Term Period has not commenced, and correspondingly the Total Commitment, will be increased by the same amount as the "Total Commitment" under the International Credit Facility is being concurrently cancelled. Accordingly, in such circumstances, the Agent and Lender acknowledge that Borrowings will not be outstanding in accordance with the revised Pro-Rata Share of each Lender and the Agent shall take all such steps as are reasonably necessary to ensure that after giving effect to any such increases, Borrowings are outstanding on a Pro-Rata Share based on the revised Total Commitment and Commitment of each Lender which is a "Switching Exempt Lender" under the International Credit Facility as soon as reasonably possible given the nature of the Borrowings then outstanding.

3.3 Purpose

Borrowings shall only be used by the Borrower for general corporate purposes (including, without limiting the generality of the foregoing, capital expenditures, acquisitions, liquidity support for a commercial paper program of the Borrower and repayment of indebtedness). Notwithstanding the foregoing or anything else contained herein, no Borrowings shall be used to fund operations, or finance investments, in any country targeted by the U.S. Economic Sanctions or to make payments to any country or any person targeted by the U.S. Economic Sanctions.

3.4 Takeover Notification

Terms defined in the Securities Act (Alberta) are used with the same meaning in this Section 3.4. In the event the Borrower wishes to utilize Borrowings to, or to provide funds to any Subsidiary to, offer to acquire outstanding securities of any person (other than a private company or a corporation whose shares are directly or indirectly held by one person and associates of such 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 twenty percent (20%) or more of all of the outstanding securities of that class of securities of the person (a "Takeover") except where such Takeover is made pursuant to exemptions from formal takeover bid requirements under applicable securities legislation or any order of any applicable securities regulatory authority, then either:

(a): Agreement of the Target Entity: the Borrower shall provide to the Agent evidence satisfactory to the Agent of the agreement of the board of directors or like body of the Target approving the Takeover; or

(b)

No Conflict by Lenders: the following steps shall be followed:

(i): no later than the close of business (Calgary time) on the fifth Business Day prior to the delivery of any notice to the Agent pursuant to Section 3.5 requesting Accommodations intended to be utilized for such Takeover, the President, Chief Financial Officer or Treasurer of the Borrower (or such other senior officer of the Borrower as may be designated by any such officer of the Borrower from time to time) shall notify the Agent of the particulars of such Takeover in sufficient detail to enable each Lender to determine whether it is a Conflicted Lender;
(ii): within one Business Day of being so notified, the Agent shall notify a Vice President or more senior officer of each Lender (or such other senior officer of such Lender as may be designated by such Lender from time to time) from whom Accommodations will be requested to fund such Takeover of the particulars of such Takeover;
(iii): no later than the third Business Day following the day on which notice is given by the Borrower to the Agent pursuant to Section 3.4(b)(i) each Lender which determines that it is a Conflicted Lender shall notify the Agent of its determination, acting reasonably, and as to whether it wishes to waive its status as a Conflicted Lender; and
(iv): the Agent shall promptly notify the President, Chief Financial Officer, Treasurer or other applicable senior officer of the Borrower of such Conflicted Lender's determination.

In the event that any Lender is a Conflicted Lender and has not waived its status as such pursuant to Section 3.4(b)(iii), 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 "Non-Conflicted Lender") shall have an obligation, up to the amount of its Commitment to provide Accommodations for such Takeover, and any such Accommodations for such Takeover shall be provided by each Non-Conflicted Lender in accordance with the ratio that its Pro-Rata Share bears to the aggregate of the Pro-Rata Shares of all the Non-Conflicted Lenders.

For the purposes of this Section 3.4, a Lender shall be a "Conflicted Lender" only if such Lender:

(A): has existing commitments (whether funded or unfunded) to provide credit to the person subject to the Takeover (including the Target);
(B): is providing financial advisory or other similar services to the person subject to the Takeover (including the Target);
(C): has other established business relationships with the person subject to the Takeover (including the Target); or
(D): has advised the Borrower of other circumstances which would make such Lender a Conflicted Lender and the Borrower, acting reasonably, has agreed such is the case.

(c): Adjustment: If Accommodations are utilized for the purposes of a Takeover (a "Takeover Loan") and there are Conflicted Lenders, the Pro-Rata Share in respect of each Non-Conflicted Lender shall be temporarily adjusted in accordance with Section 3.4(b) and subsequent Accommodations shall be funded firstly by Conflicted Lenders and subsequent repayments shall be applied firstly to amounts owed to Non-Conflicted Lenders, in each case, until such time as the Pro-Rata Share in respect of each Non-Conflicted Lender and Conflicted Lender is equal to such Pro-Rata Share in effect immediately prior to the advance of the Takeover Loan.

3.5 Borrowings

Subject to the provisions of this Agreement, the Borrower may borrow by way of Accommodations from each Lender up to such Lender's Commitment and may repay and reborrow such Accommodations:

Waiver of Presentment and Other Conditions: The Borrower waives presentment for payment and, except to the extent of the gross negligence or wilful misconduct of the Lenders referred to in the Power of Attorney Terms—Bankers' Acceptances as outlined in Schedule H hereto, any other defence to payment of any amounts due to a 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 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' Acceptance and make such additional payments, if any, as are required pursuant to Section 3.7(c).

(e)

Terms of Each Bankers' Acceptance: Each Bankers' Acceptance shall:

(i): have a maturity date which shall be on a Business Day;
(ii): subject to availability, have a Standard Term or, with respect to up to two Drawdowns only in any month, a term of seven (7) or fourteen (14) days (in each case excluding days of grace) or, with the consent of all of the Lenders such consent not to be unreasonably withheld, and subject to availability, have any other term which is not a Standard Term;
(iii): be denominated in the amount of Cdn. $100,000 and whole multiples thereof; and
(iv): shall 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 xxxx" (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 such Lenders, establish and notify the Borrower and such Lenders 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 xxxx 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.

(f): Grant of Power of Attorney: As a condition precedent to each Lender's obligation to accept and, if applicable, purchase Bankers' Acceptances hereunder, the Borrower hereby agrees to the Power of Attorney Terms—Bankers' Acceptances set out in Schedule H hereto and hereby grants to each applicable Lender a power of attorney on the terms set out in such Schedule H; provided that if the Borrower revokes such power of attorney, it shall not be entitled to issue Bankers' Acceptances hereunder unless the Borrower, the Agent and all of the Lenders have agreed on amendments to this Agreement which would allow the Borrower to again issue Bankers' Acceptances;
(g): Failure to Give Notice of Repayment: If the Borrower fails to give notice to the Agent at the Agent's Branch of Account of the method of repayment of a Bankers' Acceptance prior to the date of maturity of such Bankers' Acceptance in accordance with the same period of notice required for the original acceptance of such Bankers' Acceptance as set forth in Section 3.5, the face amount of such Bankers' Acceptance shall be converted on its maturity to a Cdn. Prime Loan pursuant to Section 3.18.
(h): Lenders Not to Purchase: The Borrower shall be entitled to elect to market on its own 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 by advising the Agent of such election in any written notice of Borrowing by way of Bankers' Acceptances in the form of Schedule A, in a Conversion Notice or in a Rollover Notice; provided that each Old System Issuer shall purchase all Bankers' Acceptances accepted by it. If the Borrower fails to advise the Lenders of any such election in any such written notice, it shall be deemed to have elected to have the Lenders purchase such Bankers' Acceptances.
(i): BA Equivalent Advances: Notwithstanding the foregoing provisions of this Section 3.7, a Non-Acceptance Lender shall, in lieu of accepting and, if applicable, purchasing, 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 on the basis the Borrower was purchasing such Bankers' Acceptances and which, but for this Section 3.7(i), such Non-Acceptance Lender would otherwise be required to accept and purchase as part of such a Borrowing 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. Concurrent with the making of a BA Equivalent Advance, a Non-Acceptance Lender shall be entitled to deduct therefrom an amount equal to the applicable Acceptance Fee which, but for this Section 3.7(i), such Non-Acceptance 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 3.7(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 necessary, be evidenced by promissory notes of the Borrower in a form satisfactory to the Borrower and such Non-Acceptance Lender, each acting reasonably.

All references in this Agreement 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.

Advice to the Lenders: The Agent, promptly following receipt of a notice of Borrowing by way of Bankers' Acceptance in the form of Schedule A or of a Conversion Notice or of a Rollover Notice, shall:

(ii): if the Borrower has elected not to market on its own such Bankers' Acceptances pursuant to Section 3.7(h), advise each such Lender of the face amount of each Bankers' Acceptance to be purchased by it and the term thereof which term shall be identical for all such Lenders. By no later than 8:00 a.m. (Calgary time), on each Drawdown Date, Conversion Date or Rollover Date, as the case may be, on which such Lenders are required to purchase Bankers' Acceptances hereunder, each Schedule I Reference Lender (in the case of Bankers' Acceptances which do not have a Standard Term) and each Schedule II Reference Lender shall notify the Agent and the Borrower of the applicable rate (as contemplated in the definition of Discount Rate) to be used by the Agent in the calculation of the Discount Rate in respect of the issuance and purchase of such Bankers' Acceptances.

(b)

Bankers' Acceptances Not Being Purchased: If the Borrower has elected to market on its own Bankers' Acceptances issued by it hereunder, the Agent, promptly following receipt of a notice of Borrowing by way of Bankers' Acceptance in the form of Schedule B and in any event prior to 9:30 a.m. (Calgary time), shall provide either written notice or telephone advice with respect to such Bankers' Acceptances to each such Lender of the amount of each issue of Bankers' Acceptances to be accepted by it or BA Equivalent Advance to be made by it, the face amount of each Bankers' Acceptance, the discounted proceeds of sale deliverable in respect thereof or the amount of the BA Equivalent Advance, the person to whom the Bankers' Acceptances have been sold and from whom the discounted proceeds of sale in respect thereof should be received, and the term thereof, which term shall be identical for all such Lenders. Such advice, if provided by telephone, shall be confirmed in writing prior to 2:30 p.m. (Calgary time) on the applicable Drawdown Date, Conversion Date or Rollover Date, as the case may be, by delivery by the Agent to each such Lender of a written confirmation.

(c)

Equivalent Advances. Such advice, if provided by telephone, shall be confirmed in writing prior to 2:30 p.m. (Calgary time) on the applicable Drawdown Date, Conversion Date or Rollover Date, as the case may be, by delivery by the Agent to each such Lender of a written confirmation.

(d): Completion of Bankers' Acceptance When Not Being Purchased: Upon receipt of notice pursuant to Section 3.8(b), each Lender is thereupon authorized to complete and sign bankers' acceptances on behalf of the Borrower in accordance with the Power of Attorney Terms—Bankers' Acceptances and the particulars advised by the Agent. Such Lenders shall then deliver such Bankers' Acceptances to the person designated to receive such Bankers' Acceptances upon receipt by each such Lender of the discounted proceeds of sale payable in respect thereof, in accordance with the particulars so advised by the Agent.
(e): Completion of Bankers' Acceptance When Being Purchased: Upon receipt of notice pursuant to Section 3.8(c), each Lender is thereupon authorized to complete and sign Bankers' Acceptances on behalf of the Borrower in accordance with the Power of Attorney Terms—Bankers' Acceptances and the particulars advised by the Agent.

3.9 Letters of Credit

(a)

Issuance: Subject to the terms and conditions set forth herein, the Agent shall issue, on behalf of the Lenders, each as to their Pro-Rata Share, Direct Letters of Credit for the account of the Borrower upon receiving an LC Application for the issuance thereof on any day on or after the Effective Date and before the last Term Date to occur. If, pursuant to an LC Application, the Borrower has requested a Fronted Letter of Credit from a Fronting Lender, such Fronting Lender shall, subject to the terms of this Agreement, issue such Fronted Letter of Credit for the account of the Borrower on any day on or after the Effective Date and before the last Term Date to occur. No Letter of Credit shall be issued (which shall include any extension of the expiry date of a then outstanding Letter of Credit) on behalf of any Lender in the case of a Direct Letter of Credit or, in the case of a Fronted Letter of Credit, by any Fronting Lender where a Lender has liability in respect thereof:

(i): if the Term Period of any such Lender has commenced except in the case of a Rollover of a Letter of Credit in place at the commencement of such Lender's Term Period where such Rollover does not extend the expiry date of such Letter of Credit beyond six (6) years from the Term Date of such Lender;
(ii): that expires more than six (6) years from the Issue Date thereof; and
(iii): if after giving effect thereto the amount of the LC Obligations under Fronted Letters of Credit issued by a Fronting Lender exceeds the Fronted LC Commitment of such Fronting Lender.

Each Direct Letter of Credit shall be substantially in the form of Schedule I and each Fronted Letter of Credit shall be substantially in the applicable Fronting Lender's standard form with modifications thereto consistent with the applicable provisions of Schedule I, in each case with any such changes to such form as:

(iv): the Agent or, if applicable, such Fronting Lender shall determine in good faith and on a commercially reasonable basis does not materially increase the obligations, or diminish the rights, of any Lender relative to such form; or
(v): the Lenders, acting reasonably, shall approve;

provided that, without the prior consent of each Lender, no Direct Letter of Credit may be issued that would vary the several and not joint nature of the obligations of the Lenders thereunder as provided in the next following sentence. Each Direct Letter of Credit shall be issued by the Agent on behalf of all

Lenders as a single multi-Lender letter of credit, but the obligation of each such Lender thereunder shall be several and not joint, based upon its Pro-Rata Share in effect on the Issue Date of such Direct Letter of Credit, subject to any change thereto as provided for therein.

(b)

Conditions Precedent: The Agent and the Lenders and, if applicable, any Fronting Lender, shall not be required to issue any Letter of Credit if on the Issue Date for such Letter of Credit the Agent determines that any of the following conditions has not been satisfied:

(i)

the Agent shall have received a Notice of Borrowing requesting that a Letter of Credit be issued, such Notice of Borrowing to be accompanied by an originally executed LC Application satisfactory to the Agent and, in the case of Fronted Letters of Credit, the applicable Fronting Lender, specifying:

(A): the proposed Issue Date (which shall be a Business Day at least two (2) Business Days following the date of such request);
(B): the purpose for which such Letter of Credit is to be used, and, if the Agent, acting reasonably, determines that the requested Letter of Credit will constitute a Standby LC, the Borrower has agreed with such characterization, failing which such Letter of Credit shall not be issued;
(C): the expiry date which shall not be more than six (6) years from the Issue Date;
(D): the name and address of the beneficiary;
(E): the face amount and currency of such Letter of Credit; and
(F): the terms and conditions of the requested Letter of Credit and other relevant details (provided that no Letter of Credit that provides for the automatic extension thereof unless notice is given to the beneficiary thereof shall be issued which requires that notice of the non-extension of the expiry date thereof be given more than 30 days prior to the scheduled expiry thereof); and

(ii)

the Agent shall have received such other customary administrative documents as it, any Lender or, if applicable, the applicable Fronting Lender, through the Agent, shall have reasonably requested as a condition to the issuance of such Letter of Credit; provided that in the event of any conflict between the terms of such other documents and this Agreement, the terms of this Agreement shall prevail and further provided that the Borrower's obligations in respect of Letters of Credit shall be determined solely by reference to the provisions of this Agreement.

(c)

Notice to Lenders: Promptly upon its receipt of an LC Application for a Letter of Credit, the Agent shall notify each Lender and, if applicable, the applicable Fronting Lender, thereof, which notice shall also specify each Lender's share of the amount of such Letter of Credit based upon such Lender's Pro-Rata Share. If the Agent or, if applicable, a Fronting Lender determines not to issue such Letter of Credit by reason of the failure to satisfy the conditions specified in Section 3.9(b)):

(i): the Agent shall give prompt notice thereof to the Borrower and each Lender (in the case of a Direct Letter of Credit); or
(ii): the Fronting Lender shall give prompt notice thereof to the Agent (in the case of a Fronted Letter of Credit) and in turn the Agent shall provide notice thereof to the Borrower and each Lender.

(d)

Direct Letters of Credit: Each Direct Letter of Credit shall be executed and delivered by the Agent in the name and on behalf of, and as attorney-in-fact for, each Lender party to such Letter of Credit. The Agent shall act under each Direct Letter of Credit as the agent of each Lender to:

(i): receive drafts, other demands for payment and other documents presented by the beneficiary under such Direct Letter of Credit;
(ii): determine whether such drafts, demands and documents are in compliance with the terms and conditions of such Direct Letter of Credit; and
(iii): notify such Lender and the Borrower that a valid drawing has been made and the date that the related LC Disbursement is to be made; provided that the Agent (in such capacity) shall have no obligation or liability for any LC Disbursement under any Direct Letter of Credit and each Direct Letter of Credit shall expressly so provide.

Each Lender hereby irrevocably appoints and designates the Agent as its attorney-in-fact, acting through any duly authorized officer of the Agent, to execute and deliver in the name and on behalf of such Lender each Direct Letter of Credit to be issued by such Lender hereunder. Promptly upon the request of the Agent, each Lender will furnish to the Agent such powers of attorney or other evidence as any beneficiary of any Direct Letter of Credit may reasonably request in order to demonstrate that the Agent has the power to act as attorney-in-fact for such Lender to execute and deliver such Direct Letter of Credit. The Borrower, the Agent and the Lenders agree that each Direct Letter of Credit shall provide that all drafts and other documents presented thereunder shall be delivered to the Agent and that all payments thereunder shall be made by the Lenders obligated thereon through the Agent at the Agent's Branch of Account. Each Lender shall be severally liable under each Direct Letter of Credit in proportion to its Pro-Rata Share on the Issue Date of such Direct Letter of Credit and each Direct Letter of Credit shall specify each Lender's share of the amount payable thereunder.

(e)

Fronted Letters of Credit: Each Fronting Lender will exercise and give the same care and attention to each Fronted Letter of Credit issued by it hereunder as it gives to its other letters of credit and similar obligations, and such Fronting Lender's sole liability to each Lender shall be to promptly return to the Agent for the account of the Lenders, each Lender's Pro-Rata Share of any payments made to such Fronting Lender by the Borrower hereunder, excluding the Fronting Fee. 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:

(i): any action taken or omitted to be taken in connection herewith at the request or with the approval of the Lenders;
(ii): any action taken or omitted to be taken in connection with any Fronted Letter of Credit in the absence of negligence or wilful 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 Person.

(f): Records: The Agent and, if applicable, the applicable Fronting Lender in the case of a Fronted Letter of Credit, shall maintain records showing the undrawn and unexpired amount of each

Letter of Credit outstanding hereunder and each Lender's share of such amount and showing for each Letter of Credit issued hereunder:

(i): the Issue Date and expiration date thereof;
(ii): the amount thereof; and
(iii): the date and amount of all payments made thereunder.

With respect to any Letter of Credit issued hereunder, the Agent and, if applicable, the applicable Fronting Lender, shall make copies of such records available to the Borrower or any Lender party to that Letter of Credit upon its request.

3.10 Direct Letter of Credit Payments

(a)

Loans: The Borrower and each Lender agree that each LC Disbursement made by a Lender under any Direct Letter of Credit shall constitute a Cdn. Prime Loan in the case of Direct Letters of Credit in Canadian Dollars, Euros or Pounds Sterling (based upon the Equivalent Amount in Canadian Dollars of any LC Disbursement made in Euros or Pounds Sterling on the date of such LC Disbursement), and a U.S. Base Rate Loan in the case of Direct Letters of Credit in U.S. Dollars, even if any condition precedent to the making of such a Loan shall not have been satisfied, in each case on the date each LC Disbursement is made by a Lender.

(b)

LC Drawdown: The Borrower and each Lender hereby authorize the Agent to review on behalf of each Lender each draft and other document presented under each Direct Letter of Credit. The determination of the Agent as to the conformity of any documents presented under a Direct Letter of Credit to the requirements of such Direct Letter of Credit shall, in the absence of the Agent's negligence or wilful misconduct, be conclusive and binding on the Borrower and each Lender. The Agent shall, within a reasonable time following its receipt thereof, examine all documents purporting to represent a demand for payment under any Direct Letter of Credit. The Agent shall promptly after such examination:

(i): notify each of the Lenders obligated under such Direct Letter of Credit and the Borrower by telephone (confirmed in writing) of such demand for payment and of each Lender's share of such payment;
(ii): deliver to each such Lender a copy of each document purporting to represent a demand for payment under such Direct Letter of Credit; and
(iii): notify each Lender and the Borrower whether said demand for payment was properly made under such Direct Letter of Credit.

LC Disbursement: With respect to any drawing determined by the Agent to have been properly made under a Direct Letter of Credit, each Lender will make an LC Disbursement in respect of such Direct Letter of Credit in accordance with its liability under such Direct Letter of Credit and this Agreement, such LC Disbursement to be made to the Agent's Branch of Account or such other account of the Agent as shall have been most recently designated by it for such purpose by notice to such Lenders. With respect to a LC Disbursement where the corresponding Letter of Credit was issued in Euros or Pounds Sterling, each Lender shall provide the Agent with an amount in Canadian Dollars sufficient to enable the Agent to purchase the necessary Euros or Pounds Sterling based on the exchange rate utilized by the Agent in accordance with its usual practices to purchase Euros or Pounds Sterling on the date such LC Disbursement is made by the Agent on behalf of such Lender. The Agent will make any such LC Disbursement available to the beneficiary of such Direct Letter of Credit by promptly remitting the amounts so received, in like funds, to the account identified by such beneficiary in connection with such demand for payment. Promptly following any LC Disbursement by any Lender in respect of any Direct Letter of Credit,

the Agent will notify the Borrower of such LC Disbursement; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligations hereunder to the Lenders with respect to any such LC Disbursement. The responsibility of the Agent in connection with any draft presented for payment under any Direct Letter of Credit shall, in addition to any payment obligation expressly provided for in such Direct Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Direct Letter of Credit. The Agent shall not be required to make any payment under a Direct Letter of Credit in excess of the amount received by it from the Lenders for such payment.

3.11 Fronted Letter of Credit Payments

(a)

LC Drawdown: The Borrower and each Lender hereby authorize each Fronting Lender to review on behalf of each Lender each draft and other document presented under each Fronted Letter of Credit. The determination of a Fronting Lender as to the conformity of any documents presented under a Fronted Letter of Credit to the requirements of such Fronted Letter of Credit shall, in the absence of such Fronting Lender's negligence or wilful misconduct, be conclusive and binding on the Borrower and each Lender. Each Fronting Lender shall, within a reasonable time following its receipt thereof, examine all documents purporting to represent a demand for payment under any Fronted Letter of Credit. Such Fronting Lender shall promptly after such examination:

(i): notify the Agent and the Borrower by telephone (confirmed in writing) of such demand for payment;

(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): each LC Disbursement shall constitute the making of a Cdn. Prime Loan in the case of a Fronted Letter of Credit in Canadian Dollars, Euros or Pounds Sterling (based upon the amount of Canadian Dollars utilized by the Agent in accordance with its usual practices to purchase Euros or Pounds Sterling, as applicable, on the date of any LC Disbursement to fund any LC Disbursement made in Euros or Pounds Sterling), or U.S. Base Rate Loan in the case of a Fronting Letter of Credit in U.S. Dollars, as applicable, to the Borrower by the applicable Fronting Lender on the Participation Date (without limiting each Lender's obligations hereunder to such Fronting Lender in respect of any such Loan and notwithstanding the otherwise pro-rata nature of Accommodations hereunder), even if any condition precedent to the making of such a Loan shall not have been satisfied;
(iii): the Agent shall notify each applicable Lender by facsimile or by telephone (confirmed by facsimile) of such disbursement and the amount payable by such Lender to the Agent for the account of such Fronting Lender based on the applicable Lender's Pro-Rata Share; and
(iv): immediately upon receipt of such notice, each applicable Lender shall make its Pro-Rata Share of such Loan in Cdn. Dollars or U.S. Dollars, as applicable, available to the Agent for the account of such Fronting Lender by wire transfer of immediately available funds to the Agent's Branch of Account for the account of such Fronting Lender.

(c)

Lenders' Participation: Each Fronting Lender irrevocably grants, and, in order to induce each Fronting Lender to issue its 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 each Lender's Pro-Rata Share) in such Fronting Lender's obligations and rights under each Fronted Letter of Credit issued by it and the amount of each draft paid by such Fronting Lender thereunder and the deemed Canadian Prime Loan or U.S. Base Rate Loan made hereunder to the Borrower on the Participation Date. Each Lender unconditionally and irrevocably agrees with such Fronting Lender that, on or before the close of business on each Participation Date, such Lender will pay to the Agent for the account of such Fronting Lender at the Agent's Branch of Account the applicable Lender's Pro-Rata Share of any Canadian Prime Loan or U.S. Base Rate Loan deemed to be made to the Borrower by such Fronting Lender on the Participation Date. If any Lender fails to make any such payment on the Participation Date, then interest shall accrue and be payable by such Lender on such Lender's obligation to make such payment during the period from such Business Day to the day such Lender makes such payment at the Default Rate.

(d)

Absolute Obligation: Each Lender acknowledges that its obligations to each Fronting Lender in respect of any Fronted Letter of Credit issued by it, 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 and the deemed Cdn. Prime Loan or U.S. Base Rate Loan made hereunder by such Fronting Lender on the Participation Date, are absolute and unconditional and shall not be affected by any circumstance whatsoever, including:

Each payment in respect of LC Expenses shall be due and payable within ten (10) Business Days after the date on which the Agent notifies the Borrower of the amount of such LC Expenses and shall accrue interest if not paid on such date at the Default Rate.

(b)

Other Costs: The Borrower shall pay to the Agent, each Fronting Lender and each Lender its:

(i): set-up fees, cable charges and other customary miscellaneous charges in respect of the issue of Letters of Credit and upon the amendment or transfer of each Letter of Credit and each drawing made thereunder; and
(ii): documentary and administrative charges for amending, transferring or drawing under, as the case may be, Letters of Credit of a similar amount, term and risks.

3.14 Indemnification; Nature of Lender's Duties

(a)

Indemnity: In addition to amounts payable as elsewhere provided for in this Article 3, the Borrower hereby agrees to protect, indemnify, pay and save each Lender harmless from and against any and all claims or losses (including reasonable legal fees and expenses) which such Lender may incur or be subject to as a consequence, direct or indirect, of:

(i): the application for or issuance of or drawing under any Letter of Credit, other than as a result of the negligence or wilful misconduct of such Lender as determined by a court of competent jurisdiction, provided that such Lender acts in good faith; or
(ii): the failure of such Lender to honour a drawing under any Letter of Credit as a result of any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or governmental authority prohibiting the payment of such drawing (all such acts or omissions herein called "Government Acts").

(b)

Misuse: As between the Borrower and each Lender, the Borrower assumes all risks of the acts and omissions of, or misuse of any Letter of Credit by, the beneficiary of such Letter of Credit. Except to ensure compliance with the applicable Letter of Credit, the Lenders shall not have any responsibility for:

(i): the form, validity, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for, issuance of or drawing under any Letter of Credit (even if it should in fact prove to be in any or all respects invalid, inaccurate, fraudulent or forged);
(ii): the validity or sufficiency of any instrument transferring or assigning (or purporting to transfer or assign) any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason;
(iii): errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph or otherwise (whether or not they are in cipher);
(iv): errors in interpretation of technical terms;

(v): any loss or delay in the transmission or otherwise of any document required in order to make a drawing under any Letter of Credit or of the proceeds thereof;
(vi): the misapplication by the beneficiary of any Letter of Credit or of the proceeds of any drawing under such Letter of Credit; and
(vii): any consequences arising from causes beyond the control of the Lenders, including any Government Acts.

None of the above shall affect, impair, or prevent the vesting of any of the Lenders' powers hereunder. Any action taken or omitted by any Lender under or in connection with any Letter of Credit issued by it or the related certificates if taken or omitted in good faith, shall not put such Lender under any resulting liability to the Borrower provided that such Lender acts without negligence and has not engaged in wilful misconduct.

(c): No Liability: The Borrower shall have no obligation to indemnify a Lender in respect of any liability incurred by such Lender arising out of the gross negligence or wilful misconduct of such Lender as determined by a court of competent jurisdiction, or out of the wrongful dishonour by such Lender of a proper demand for payment made under any Letter of Credit issued by it.

3.15 Repayments re Letters of Credit

If:

(a): the Agent delivers an Acceleration Notice or an Event of Default occurs under Section 9.1(c) or 9.1(d);
(b): the Borrower shall be required to repay Borrowings to a Lender pursuant to Article 4; or
(c): any Letter of Credit is the subject matter of any order, judgement, injunction or other such determination (a "Judicial Order") restricting payment under and in accordance with such Letter of Credit or extending the Lender's or Fronting Lender's liability, as the case may be, beyond the expiration date stated in such Letter of Credit;

then the Borrower shall pay to the Agent an amount, in the currency in which the Letter of Credit is denominated, equal to the maximum amount available to be drawn under any unexpired Letter of Credit in respect of all of the Lenders in the case of paragraphs (a) and (c) and in respect of each Lender whose Borrowings are required to be repaid in accordance with Article 4 in the case of paragraph (b). Any such amounts paid by the Borrower to the Agent shall be held by the Agent in interest bearing cash collateral accounts (with interest payable for the account of the Borrower at the rates and in accordance with the then prevailing practices of the Agent for accounts of such type) as continuing collateral security for the obligations of the Borrower to reimburse the Lenders for LC Disbursements made in respect of any such Letter of Credit. Such cash collateral accounts shall be assigned to the Agent as security for the obligations of the Borrower in relation to such Letters of Credit and the Security Interest of the Agent thereby created in such cash collateral shall rank in priority to all other Security Interests and adverse claims against such cash collateral. Such cash collateral shall be applied to satisfy the obligations of the Borrower for such Letters of Credit as LC Disbursements are made thereunder. Amounts held in such cash collateral accounts may not be withdrawn by the Borrower; however, interest on such deposited amounts (at the rates and in accordance with the then prevailing practices of the Agent for accounts of such type) shall be for the account of the Borrower and may be withdrawn by the Borrower from time to time so long as no Event of Default is then continuing.

The Agent shall release to the Borrower any amount remaining in the cash collateral accounts after applying the amounts necessary to discharge all obligations of the Borrower relating to such Letters of Credit, upon the later of:

(d)

the date on which any final and non-appealable order, judgement or other determination has been rendered or issued either terminating any applicable Judicial Order or permanently enjoining the Lenders or the Fronting Lender, as the case may be, from paying under such Letter of Credit;

(e)

the earlier of:

(i): the date on which either the original counterpart of such Letter of Credit is returned to the Agent or the Fronting Lender, as the case may be, for cancellation or the Lenders or the Fronting Lender, as the case may be, are or is released by the beneficiary thereof from any other obligation in respect of such Letter of Credit; and
(ii): the expiry of such Letter of Credit; and

(f)

if an Event of Default has occurred, the payment and satisfaction of all indebtedness and liabilities of the Borrower hereunder and cancellation or termination of the Credit Facility.

3.16 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 3.5 for the initial drawdown of the basis of Borrowing being repaid, such notice to be substantially in the form of Schedule A. 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 Section 10.5, only be repaid on the last day of the Libor Interest Period related thereto.

3.17 Pro-Rata Treatment of Borrowings

(a)

Pro-Rata Borrowings: Subject to Section 3.2, Section 3.4(c), Section 3.9(a)(i), Section 3.18(b) and this Section 3.17(a) and that there may be Lenders whose Commitment is a revolving credit facility and Lenders whose Commitment is no longer a revolving credit facility, each Accommodation 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 each Lender will, to the extent possible, thereafter be in the same proportion as the Pro-Rata Share of such Lender. The Agent is authorized by the Borrower and each Lender to determine, in its discretion, acting reasonably, the amount of Borrowings 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 3.17(a) and Section 6.2; provided that no Lender shall, as a result of any such determination, have Borrowings outstanding (determined with reference to the Equivalent Amount thereof in Canadian Dollars) in an amount which is in excess of the amount of its Commitment.

(b)

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

(i): allocate each basis of Borrowing in accordance with Section 3.17(a) by reason of the occurrence of circumstances described in Section 10.2 or Section 10.3; or
(ii): allocate Bankers' Acceptances and BA Equivalent Advances to each Lender in accordance with Section 3.17(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 such Lender to make such allocation as the Agent determines in its discretion, acting reasonably, may be equitable in the circumstances but no Lender shall, as a result of any such allocation, have Borrowings outstanding (determined as the Equivalent Amount thereof in Canadian Dollars) in an amount which is in excess of the amount of its Commitment.

(c): 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 3.17.

3.18 Conversions

The Borrower may, during the term of this Agreement, upon giving the Agent at the Agent's Branch of Account a Conversion Notice in accordance with the period of prior notice and other requirements set out in Section 3.5 (other than delivery of a notice in the form of Schedule A) in respect of the basis of Borrowing to which any Borrowing is being converted, convert any Borrowing to another basis of Borrowing. Notwithstanding the foregoing, 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. A Letter of Credit may not be converted. If the requested conversion is either from or into Libor Loans or Bankers' Acceptances, then:

(a): if a Default has occurred and is continuing, the Borrower, without limiting its rights to convert any Borrowing into a Cdn. Prime Loan or a U.S. Base Rate Loan, as applicable, shall only be entitled to request a conversion into a Libor Loan with a Libor Interest Period of one (1) month or into a Bankers' Acceptance with a term to maturity of one (1) month or less as provided for herein unless the Agent, in its discretion acting reasonably, otherwise permits; and
(b): if an Event of Default has occurred and is continuing, such conversion shall not be permitted unless the Agent in its discretion otherwise agrees and all Libor Loans in respect of which any such conversion has been requested shall be converted to a Cdn. Prime Loan in the case of Libor Loans denominated in Canadian Dollars, Euros or Pounds Sterling or to a U.S. Base Rate Loan in the case of Libor Loans denominated in U.S. Dollars, in each case on the last day of the Libor Interest Period applicable thereto and all Bankers' Acceptances in respect of which any such conversion has been requested shall be converted to a Cdn. Prime Loan on the maturity of such Bankers' Acceptances.

On each Conversion Date, the Borrower, subject to Section 3.7(c), shall be required to repay to the Agent the basis of Borrowing which is being converted and, subject to the provisions of this Agreement, the Lenders shall be required to make available to the Borrower the Borrowings into which such basis of Borrowing is being converted.

3.19 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 or extend the expiry date of a Letter of Credit, upon giving the Agent at the Agent's Branch of Account a Rollover Notice in accordance with the period of notice and other requirements set out in Section 3.5 applicable to Bankers' Acceptances or Libor Loans or Letters of Credit (other than delivery of a notice in the form of Schedule A), unless immediately prior to the issuance of any Bankers' Acceptances or Letter of Credit 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 not be entitled to

Rollover such Letter of Credit and, in the case of a Default, shall only be entitled to request a Bankers' Acceptance with a term to maturity of one (1) month or less as provided for herein or a Libor Interest Period of one (1) month unless the Agent, in its discretion acting reasonably, otherwise permits and, in the case of an Event of Default, shall be deemed to have converted any Bankers' Acceptance to a Cdn. Prime Loan and any such Libor Loan which is denominated in Canadian Dollars, Euros or Pounds Sterling to a Cdn. Prime Loan and any such Libor Loan which is denominated in U.S. Dollars to U.S. Base Rate Loan, in each case pursuant to Section 3.18 on the maturity date of the Bankers' Acceptance or the last day of the Libor Interest Period applicable thereto, in each case unless the Agent in its discretion acting reasonably, otherwise permits. In the event a Rollover Notice in respect of an existing Bankers' Acceptance or Libor Loan is not given pursuant to this Section 3.19 or a Conversion Notice in respect of such existing Bankers' Acceptance or Libor Loan is not given pursuant to Section 3.18, any such Bankers' Acceptance shall be converted to a Cdn. Prime Loan on the maturity date of such Bankers' Acceptance and any such Libor Loan which is denominated in Canadian Dollars, Euros or Pounds Sterling shall be converted to a Cdn. Prime Loan and any such Libor Loan which is denominated in U.S. Dollars shall be converted to a U.S. Base Rate Loan, in each case on the last day of the Libor Interest Period applicable to such existing Libor Loan and the provisions of the last sentence of Section 3.10 shall apply to any such conversion.

3.20 Notices Irrevocable

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

3.21 Extension of Term Date

(a)

Request for an Offer of Extension: The Borrower may from time to time request an offer to extend the Term Date of each Lender whose Term Period has not yet commenced (each, a "Requested Lender") by sending to the Agent a Request for an Offer of Extension not later than forty-five (45) days prior to the then current Term Date and not earlier than ninety (90) days prior to the then current Term Date, and the Agent shall forthwith, and in any event within two (2) Business Days, notify each Requested Lender of such request. Each Requested Lender shall advise the Agent as to whether it agrees to make an offer to the Borrower to extend the Term Date in accordance with any such Request for an Offer of Extension within thirty (30) days of the delivery by the Borrower to the Agent of the Request for an Offer of Extension, provided that in the event any 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 make an offer to the Borrower to extend the Term Date. Forthwith and in any event within two (2) Business Days of the Agent receiving from each Requested Lender its decision with respect to making an offer to the Borrower to extend the Term Date, the Agent shall, subject to Section 3.21(c), provide the Borrower with an offer to extend the Term Date in accordance with Section 3.21(d) or 3.21(e), as the case may be, and the Borrower, subject to Section 3.21(g), shall be entitled to accept any such offer at any time up to and including the last Business Day preceding the then current Term Date by written notice to the Agent of such acceptance.

(b)

Payment or Replacement by Borrower: Subject to Section 3.21(c), if a Requested Lender does not agree to make an offer to extend the Term Date (such Requested Lender being a "Non-Agreeing Lender" and any Requested Lender agreeing to make an offer to extend the Term Date applicable to it being an "Agreeing Lender") the Borrower may, but is not obligated, to:

(i): so long as there exists no Default or Event of Default and subject to Section 10.5, repay all Borrowings and other amounts owing hereunder to any Non-Agreeing Lender on or prior to the then current Term Date and upon such payment any Non-Agreeing Lender shall cease to

be a Lender hereunder and each such Non-Agreeing Lender's Commitment shall be terminated and the Total Commitment reduced accordingly; or

(ii): arrange for a replacement lender or lenders (which may be one or more of the Lenders) to replace each Non-Agreeing 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 (such approval not to be unreasonably withheld or delayed) and shall be novated into the Loan Documents in the place and stead of the Non-Agreeing Lender by execution of all necessary documentation on or prior to the then current Term 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 Agent shall not provide the Borrower with an offer to extend the Term Date in accordance with Section 3.21(a) if Requested Lenders holding more than thirty-three and one third percent (33¹/3%) of the aggregate of the Commitments of all Requested Lenders do not agree or are deemed not to agree to make an offer to the Borrower to extend the Term Date pursuant to the Request for an Offer of Extension. In any such case, the Term Date of each Requested Lender shall not be extended and the Term Period shall commence for all Requested Lenders on the then current Term Date.

(d)

Extension for all Requested Lenders: If all Requested Lenders agree to make an offer to the Borrower to extend the Term Date pursuant to a Request for an Offer of Extension and the Borrower accepts the applicable offer in accordance with Section 3.21(a), then the Term Date of each Requested Lender shall be extended for a period of three hundred and sixty-four (364) days from the date of the acceptance by the Borrower of the offer made to it to extend the Term Date by the Agent on behalf of such Requested Lenders.

(e)

Partial Extension: If, with respect to any Request for an Offer of Extension, the provisions of Section 3.21(c) or 3.21(d) are not applicable and there are Non-Agreeing Lenders under Section 3.21(b), then:

(i): the Term Date for all Agreeing Lenders in respect of whom the Borrower has accepted the offer made by them to extend the Term Date (such Agreeing Lenders being "Extending Lenders"), shall be extended for a period of three hundred and sixty-four (364) days from the date of the acceptance by the Borrower of the offer made to it to extend the Term Date by the Agent on behalf of such Lenders; and
(ii): the Term Date for each such Non-Agreeing Lender shall not be extended and the Term Period of each such Non-Agreeing Lender shall commence on the then current Term Date.

(f)

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

(g)

Default or Event of Default: Notwithstanding the foregoing, the Borrower shall not be entitled to provide to the Agent a Request for an Offer of Extension if an Event of Default has occurred and is then continuing and shall not be entitled to accept any offer made by the Agent on behalf of the Agreeing Lenders to extend the Term Date if a Default or Event of Default has occurred and is continuing at the time of purported acceptance unless either the Default was subsisting at the time any Request for an Offer of Extension was made by the Borrower and the Borrower had advised the Agent thereof or, in any other case, such Default or Event of Default is waived by all of the Agreeing Lenders; provided that any such waiver shall be effective only for the purposes of this Section 3.21 unless otherwise specified by the Agreeing Lenders but any such specification shall not bind any Lenders who are not Agreeing Lenders.

3.22 Increase of Total Commitment

The Borrower may at any time and from time to time and provided the Term Period has not commenced for any Lender, 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 aggregate of the Total Commitment hereunder and the "Total Commitment" under the International Credit Facility does not exceed Cdn. $1,500,000,000;
(c): the Agent and each Fronting Lender has consented to such financial institution becoming a Lender, if it is not already a Lender, such consent not to be unreasonably withheld or delayed;
(d): 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 in respect of whom the Term Period has not yet commenced and including therein such additional financial institution, are in accordance with the Pro-Rata Share of all such Lenders (including the new financial 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
(e): 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) 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.

ARTICLE 4
REPAYMENT AND PREPAYMENT

4.1 Reduction of Commitment and Repayment of Borrowings

On the Term Date of each Lender, the Commitment of such Lender shall become equal to the lesser of the Equivalent Amount in Canadian Dollars of the Borrowings outstanding to such Lender on such Term Date and the Commitment of such Lender on such Term Date and, to the extent that the Equivalent Amount in Canadian Dollars of the Borrowings on such Term Date is in excess of such Commitment after giving effect to the foregoing, the Borrower shall, within five (5) Business Days, repay such excess. On the Maturity Date of each Lender, the Borrower shall repay all Borrowings then outstanding to such Lender (including, without limitation, posting cash collateral with respect to Letters of Credit as required by Section 3.15(a)) and the Commitment of such Lender shall be reduced to zero. The Borrower shall ensure that all Libor Loans and Bankers' Acceptances and BA Equivalent Advances forming a part of Borrowings of such Lender mature on or before the Maturity Date of such Lender.

4.2 Repayment of Borrowings due to Exchange Rate Fluctuations

If, due to exchange rate fluctuations, the amount of Borrowings (determined in Canadian Dollars with all Borrowings denominated in U.S. Dollars, Euros and Pounds Sterling being converted to the Equivalent Amount in Canadian Dollars) outstanding on any Business Day to any Lender exceeds the amount of such Lender's Commitment:

(a): by more than five percent (5%) on a day other than a Drawdown Date, Conversion Date or Rollover Date, the Agent shall advise the Borrower in writing of the amount of such excess and

the Borrower shall, within five (5) Business Days thereafter, 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 the excess then subsisting; or

(b): by any amount on a Drawdown Date, Conversion Date or Rollover Date, the Borrower shall as part of such drawdown, Rollover or Conversion reduce or eliminate such excess on such date.

4.3 Cancellation 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 A, cancel all or any portion of the Total Commitment or the Fronted LC Commitment of any Fronting Lender, as determined by the Borrower in its discretion, in each case in minimum amounts equal to the lesser of Cdn. $5,000,000 and the remaining balance of such Total Commitment or Fronted LC Commitment, as applicable, and multiples of Cdn. $5,000,000 thereafter if, on or prior to the last day of such notice period, the Borrower has:

(a): in the case of a cancellation of the Total Commitment, prepaid or otherwise reduced Borrowings outstanding to each Lender in an amount equal to the amount by which 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): in the event such cancellation is in respect of all of the Total Commitment or the Fronted LC Commitment, as applicable, paid all accrued interest and other charges and fees in respect of the Borrowings or Fronted LC Commitment being repaid or reduced as aforesaid; and
(c): in the case of the cancellation of the entire Fronted LC Commitment of any Fronting Lender, the Borrower has, on or prior to the effective date of any such cancellation, returned to the Fronting Lender for cancellation all Fronted Letters of Credit issued by such Fronting Lender.

Any such notice of cancellation shall be irrevocable and the amount of the Total Commitment and the Commitment or the Fronted LC Commitment, as applicable, of each Lender or Fronting Lender, as applicable, so cancelled and reduced shall not be reinstated hereunder.

4.4 Cancellation or Transfer of a Lender's Commitment

If:

(a): any payment is required to be made by the Borrower to a Lender or Lenders (but not to all of the Lenders) pursuant to Section 6.3;
(b): any Lender or Lenders give(s) notice to the Borrower that Additional Compensation is payable by the Borrower to such Lender or Lenders (but not to all of the Lenders) pursuant to Section 10.2;

(d): a Lender does not provide its consent or agreement to a request by the Borrower for a waiver or amendment which requires the consent of all of the Lenders as provided for in Section 11.12(a);
(e): a Conflicted Lender does not waive its status as such pursuant to Section 3.4(b)(iii);
(f): a Fronting Lender does not consent on a timely basis to a new or replacement Lender becoming a Lender pursuant to Section 3.21, 3.22 or this Section 4.4;
(g): the Commitment of a Lender and its Affiliates is less than Cdn. $10,000,000; or

(h): a Lender fails to provide an Accommodation or Borrowing as and when required hereunder and such failure remains uncured for a period of two (2) Business Days after notice thereof by the Borrower to such 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 and without regard to Section 4.3:

(i): upon at least five (5) Business Days prior written notice to the Agent (other than in the case of Section 4.4(h) in which case written notice may be effective immediately), irrevocably cancel all but not part of the Affected Lender's Commitment (which shall include its Fronted LC Commitment, if any) if on or prior to the last day of such notice period the Borrower has prepaid or otherwise reduced all Borrowings outstanding to such Affected Lender, and paid all accrued interest and other charges and fees in respect of such Borrowings and Fronted Letters of Credit and, if such Lender is a Fronting Lender, returned to such Fronting Lender all Fronted Letters of Credit issued by it for cancellation; or
(j): within sixty (60) days of a Lender becoming an Affected Lender, arrange for a replacement lender or lenders (provided that such lender or lenders, if not a Lender, shall be approved by the Agent and each Fronting Lender, such approval not to be unreasonably withheld or delayed) to replace the Affected Lender's Commitment and any such replacement lender shall be novated into this Agreement in the place and stead of the Affected Lender upon payment to the Affected Lender of the amounts referred to in Section 4.4(i) hereof.

provided that, notwithstanding the foregoing, the Borrower may exercise its rights under either Section 4.4(i) and 4.4(j) pursuant to Section 4.4(d) if a Default has occurred and is continuing provided that all Lenders other than the Affected Lender have provided the consent or agreement required pursuant to Section 11.12(a) and that by exercising such rights the Default is cured or waived by all Lenders after giving effect to any such cancellation or replacement, as the case may be. If, in any circumstance, there is more than one Affected Lender, the Borrower shall deal with all such Affected Lenders in an equivalent manner.

4.5 Early Repayment

The Borrower shall not cancel all or any portion of the Total Commitment pursuant to Sections 4.3 or 4.4 if the 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 or Bankers' Acceptances with a maturity date falling subsequent to the date of such cancellation or Letters of Credit with an expiry date ending 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 in respect of Libor Loans, the amount required to be paid pursuant to Section 10.5 and, in respect of Bankers' Acceptances, the face amount of any such Bankers' Acceptance (in which case the Agent shall pay to the Borrower its then current best rate for deposits of equal amounts for a term equal to the remaining term of such Bankers' Acceptance) and, in respect of Letters of Credit, an amount equal to the undrawn amount of all such outstanding Letters of Credit in accordance with Section 3.15(a).

4.6 Evidence of Indebtedness

The Agent shall open and maintain on the books of the Agent's Branch of Account, accounts and records 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 the Borrowings and interest thereon and fees and other amounts payable pursuant to this Agreement and shall record the Bankers' Acceptances accepted by each 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 Borrowings and interest thereon and fees payable pursuant to this Agreement and other amounts owing hereunder.

ARTICLE 5
PAYMENT OF INTEREST AND FEES

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 each Lender at a rate per three hundred sixty-five (365) day period or three hundred sixty-six (366) day period, as the case may be, equal to the Cdn. Prime Rate plus the applicable Margin. A change in the Cdn. Prime Rate or the Margin will, in accordance with Section 5.12, 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 the Interest 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 or three hundred sixty-six (366) days, as applicable. The annual rates of interest to which the rates determined in accordance with the foregoing provisions of this Section 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) or three hundred sixty-six (366), as applicable.

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 each Lender at a rate per three hundred sixty-five (365) day period or three hundred sixty-six (366) day period, as the case may be, equal to the U.S. Base Rate plus the applicable Margin. A change in the U.S. Base Rate or the Margin will, in accordance with Section 5.12, 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 the Interest 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 or three hundred sixty-six (366) days, as applicable. 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) or three hundred sixty-six (366), as applicable.

5.3 Interest on Libor Loans

The Borrower shall pay interest in Canadian Dollars, U.S. Dollars, Euros or Pounds Sterling, as applicable, to the Agent on behalf of each Lender on each Libor Loan made by each Lender 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 for Libor Loans denominated in Canadian Dollars, U.S. Dollars and Euros and per three hundred sixty-five (365) day period for Libor Loans denominated in Pounds Sterling, equal to the sum of Libor plus the applicable Margin. A change in the Margin will, in accordance with Section 5.12, simultaneously cause a corresponding change in the interest payable for a Libor Loan. 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) or three hundred sixty-five (365), as applicable.

5.4 Bankers' Acceptance Fees

The Borrower shall pay a fee in Canadian Dollars to the Agent on behalf of each Lender on each Bankers' Acceptance accepted by such Lender ("Acceptance Fees").

The annual rate of fees to which the Acceptance Fees are equivalent, are the fees 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 fee is payable and divided by three hundred and sixty-five (365). Acceptance Fees payable to the Lenders pursuant to this Section 5.4 shall be paid in the manner specified in Section 3.7. All Acceptance Fees payable 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 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 forthwith credit any amount which would otherwise be refundable to the Borrower against amounts in respect of interest or fees accruing hereunder.

5.5 Letter of Credit Fees

(a): LC Fees: In consideration of each Lender's commitment to issue Direct Letters of Credit under this Agreement or be liable for its Pro-Rata Share of Fronted Letters of Credit under this Agreement, the Borrower hereby agrees to pay to the Agent, for the rateable account of each Lender (in proportion to such Lender's share of the undrawn and unexpired amounts of all outstanding Letters of Credit), a letter of credit fee (the "LC Fees") computed at the Margin multiplied by the average daily aggregate then undrawn and unexpired amount of the Letters of Credit outstanding during the period (or any portion thereof) for which payment is being made, payable quarterly in arrears for the Fiscal Quarter or portion thereof then ended on the first Business Day of the following calendar quarter and, as to each Lender, on the Maturity Date

applicable to such Lender, as applicable, and thereafter where a Letter of Credit remains outstanding after the Maturity Date of a Lender, on the first Business Day of each Fiscal Quarter occurring after the Maturity Date and on the expiry date of such Letter of Credit. The LC Fees shall be calculated on the basis of the actual number of days elapsed in a year of three hundred sixty-five (365) days.

(b): Fronting Fees: In consideration of each Fronting Lender agreeing to issue Fronted Letters of Credit under this Agreement, the Borrower hereby agrees to pay directly to such Fronting Lender, a fronting fee (the "Fronting Fee") computed at the Fronting Fee Rate multiplied by the average daily aggregate then undrawn and unexpired amount of the Fronted Letters of Credit issued by such Fronting Lender outstanding during the period (or any portion thereof) for which payment is being made, payable quarterly in arrears on the first Business Day of the following calendar quarter and on the Maturity Date and thereafter where a Letter of Credit remains outstanding after the Maturity Date of such Fronting Lender, on the first Business Day after each Fiscal Quarter occurring after the Maturity Date and on the expiry date of such Letter of Credit. The Fronting Fees shall be calculated on the basis of the actual number of days elapsed in a year of three hundred sixty-five (365) days.

5.6 Utilization Fees

The Borrower agrees that it shall pay to the Agent, for the benefit of the Lenders, a utilization fee ("Utilization Fees") in Canadian Dollars, in addition to the Margin, on Borrowings if at any time the aggregate of the Equivalent Amount in Canadian Dollars of all Borrowings hereunder is greater than 33% of the Total Commitment and for so long as such is the case (the "Utilization Fee Period"). The utilization fee shall be 10 bps and shall be calculated on the Equivalent Amount in Canadian Dollars of all Borrowings outstanding at the commencement of the Utilization Fee Period and on the Equivalent Amount in Canadian Dollars of all Borrowings made during the Utilization Fee Period. The utilization fee shall be payable quarterly in arrears by the Borrower on the first Business Day of each calendar quarter and on the Maturity Dates of the respective Lenders. Each payment of utilization fees shall be calculated for the period commencing on and including the first day of the immediately prior calendar quarter or the date of this Agreement, as the case may be, up to and including the last day of such immediately prior calendar quarter or the Maturity Date, as applicable, but only for each Utilization Fee Period in any such period. Such utilization fees shall be calculated on a daily basis on the basis of the actual number of days elapsed in a year of three hundred sixty-five (365) days. For the purposes of calculating whether utilization fees are payable pursuant to this Section 5.6, the amount of all Borrowings outstanding on each day in U.S. Dollars, Euros and Pounds Sterling shall be notionally converted to the Equivalent Amount in Canadian Dollars at the rate of exchange in effect for the purposes of determining an Equivalent Amount on such day.

5.7 Interest on Overdue Amounts

The Borrower shall, on demand, pay to the Agent on behalf of each Lender interest on all overdue payments in connection with this Agreement from the date any such payment becomes overdue and for so long as such amount remains unpaid at a rate per annum which is equal to:

(a): the Cdn. Prime Rate plus one percent (1%) in respect of all amounts due in Canadian Dollars; and
(b): the U.S. Base Rate plus one percent (1%) in respect of all amounts due in U.S. Dollars, Euros and Pounds Sterling.

Such interest on overdue amounts shall be computed daily, compounded monthly and shall be payable both before and after default, maturity and judgment.

5.8 Standby Fees

The Borrower shall pay standby fees to each Lender in Canadian Dollars to the Agent on behalf of each Lender 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 date hereof. Each payment of standby fees shall be calculated for the period commencing on and including the date hereof or the last date for 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 Term Date applicable to each Lender (as applicable and whichever is earlier) and shall be in an amount equal to the Standby Fee Rate in effect on each day during such period 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. For purposes of calculating standby fees payable pursuant to this Section 5.8, the amount of Borrowings outstanding from time to time in U.S. Dollars, Euros or Pounds Sterling, as applicable, on each day during the period for which such standby fees are payable shall be notionally converted to the Equivalent Amount in Canadian Dollars at the rate of exchange in effect for purposes of determining an Equivalent Amount on the first day of each month for such month or portion thereof in the calculation 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 or three hundred sixty-six (366) days, as the case may be.

5.9 Agent's Fees

The Borrower shall pay agency fees to the Agent for the Agent's sole account at the Agent's Account for Payments at the time or times and in the amount agreed to in writing by the Borrower and the Agent and such fees shall, for purposes of this Agreement, be deemed to be an amount payable pursuant to this Agreement.

5.10 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 accordance with such section) on any amount of "credit advanced" (as defined in that section) pursuant to this Agreement or any agreement or arrangement collateral hereto entered into in consequence or implementation hereof would, but for this Section 5.10, 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 the 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 the Lender has received a payment or partial payment which would, but for this Section 5.10, be so prohibited then any amount or amounts so received by the Lender in excess of the adjusted rate shall and shall comprise and be deemed to have comprised a credit to be applied (together with interest thereon at the adjusted rate from the date of receipt of any such amount by the Lender to the date of its application as hereinafter provided) to subsequent payments on account of interest, fees or other amounts due to the Lender at the adjusted rate.

5.11 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.

5.12 Interest and Fee Adjustment

All interest and fees payable pursuant to Sections 5.1, 5.2, 5.3, 5.4, 5.5, 5.6 and 5.8 which are to be adjusted as a result of a change in the rating by any Rating Agency of the long term senior unsecured and unsubordinated debt of the Borrower and a corresponding change in the Margin, shall be adjusted effective on the date of such change in such rating and the Borrower and the Lenders shall make all adjustments as are necessary to give effect to any such change.

ARTICLE 6

If any day on which any amounts are payable hereunder is not a Business Day, such amount shall be deemed for all purposes of this Agreement to be due on the Business Day next following such day and such extension of time shall in such case be included in the computation of the payment of any interest or fees payable under this Agreement. Unless otherwise specifically provided for herein, all payments required to be made by the Borrower or a Lender shall be made to the Agent's Account for Payments.

Except as otherwise agreed to by all of the Lenders in their sole discretion, all payments made by or on behalf of the Borrower pursuant to this Agreement prior to the delivery of an Acceleration Notice or the occurrence of an Event of Default specified in Section 9.1(c) or Section 9.1(d) shall (subject to Section 3.4(c) or Section 4.4(i)) be applied rateably among the Lenders and the Agent in accordance with amounts owed to such Lenders and the Agent in respect of each category of amounts set forth below, each such application to be made to the category or categories specified by the Borrower or, failing such direction, shall be made in the following order with the balance remaining after application in respect of each category to be applied to the next succeeding category:

with the balance to be applied to repay or otherwise reduce Borrowings in a manner so that the Borrowings and each basis of Borrowing outstanding hereunder to each Lender will, to the extent possible, be in the same proportion as the Pro-Rata Share of such Lender in respect of such Borrowings.

6.3 Taxes

(a)

Withholding: The Borrower agrees that any and all payments by the Borrower to or for the benefit of the Lenders under this Agreement shall be, except as required by applicable law or expressly provided in this Section 6.3(a) and Section 12.1, free and clear of and without set off, counterclaim, reduction or deduction for any and all present or future Taxes imposed by or on behalf of Canada or any political subdivision thereof, other than Excluded Taxes. If the Borrower shall be required to deduct or withhold any Taxes (other than Excluded Taxes) from or in respect of any sum payable hereunder to any Lender:

(i): the sum payable shall be increased as may be necessary so that, after making all required deductions or withholdings (including deductions applicable to additional sums payable under this Section 6.3(a)), such Lender has received an amount equal to the sum it would have received had no such deductions or withholdings been made and the Borrower hereby agrees to indemnify each Lender, as applicable, on an after-tax basis for any additional taxes on net income that such Lender may be obliged to pay as a result of the receipt of any such additional sums under this Section 6.3(a)(i);
(ii): the Borrower shall make such deductions or withholdings; and
(iii): the Borrower shall pay the full amount deducted or withheld to the relevant taxing authority or other authority in accordance with applicable law and shall provide the Agent with copies of official receipts or other documentation evidencing such payment within a reasonable period of time from receipt by it of such receipts or other documentation.

If the Borrower is required by law to withhold, deduct or otherwise reduce or set-off amounts from any payments hereunder, but the Borrower is not required to make a corresponding increase in the sum payable pursuant to clause 6.3(a)(i) above, the Borrower shall notify the Agent in writing of the amount it has withheld, or intends to withhold, from any payment hereunder in respect of such legal requirement or, if the Agent and the Borrower so agree, the Agent may make or confirm such calculations as may be requisite to determine the amount of the required withholding and notify the Borrower thereof in writing. Provided that the amount stated by the Borrower in any such notice given by it was determined by the Borrower in good faith, the Borrower shall not be considered to be in default hereunder, or to have failed to make any required payment hereunder, for any purpose if the Borrower withholds from any such payment the amount set forth in any such notice.

(b): Refunds: If any Taxes (other than Excluded Taxes) are imposed on or with respect to any payment on or under this Agreement, in consequence of which the Borrower is required to make any additional payment to any Lender under Section 6.3(a), and if such Lender is entitled to a cash refund or to a credit which is applied against Taxes otherwise payable in a taxation year of a Lender and in either case which is both identifiable and quantifiable by such Lender as being attributable to the imposition of such Taxes (a "Tax Refund"), and such Tax Refund may be obtained without increased liability to such Lender by filing one or more forms, certificates, documents, applications or returns (collectively, the "Forms"), then such Lender shall notify the Borrower and shall, if requested by the Borrower, file such Forms in a timely fashion. If such Lender subsequently receives a Tax Refund, and such Lender is able to identify the Tax Refund as being attributable, in whole or in part, to the Tax with respect to which such additional payment was made, then such Lender shall promptly reimburse the Borrower such amount as such Lender shall determine acting reasonably and in good faith to be the proportion of the Tax Refund, together with any interest received thereon, attributable to such additional payment as will leave such Lender after the reimbursement in the same position as it would have been if the additional payment had not been required; provided that, if any Tax Refund reimbursed by a Lender to the Borrower is subsequently disallowed, the Borrower shall repay such Lender such amount (together

with interest and, if such refund resulted from a request by the Borrower, any applicable penalty payable by such Lender to the relevant taxing authority) promptly after receipt of notice by such Lender of such disallowance. The Borrower agrees to reimburse each such Lender for such Lender's reasonable out-of-pocket expenses, if any, incurred in complying with any request hereunder and agrees that all costs incurred by such Lender in respect of this Section 6.3(b) may be deducted from the amount of any reimbursement to the Borrower in respect of any Tax Refund pursuant to this Section 6.3(b).

(c)

Cooperation: In the event that the Borrower makes any indemnification payment to a Lender under Section 6.3 and in the event the Borrower determines in its good faith judgment that the Lender is not liable for the Taxes for which such indemnification payment was made, such Lender agrees to use reasonable efforts to cooperate with the Borrower in contesting the liability for such Taxes; provided that, the Borrower shall reimburse such Lender for any reasonable out-of-pocket costs and expenses incurred in providing such cooperation and shall indemnify and hold such Lender harmless from and against any liabilities incurred as a result of such Lender providing such cooperation or contesting such liability, and provided further that no such cooperation shall be required if such contest shall in such Lender's good faith judgment subject it to any liability not covered by such indemnity.

(d)

Representations of Schedule III Lenders: By its execution hereof, each Lender that is not listed on Schedule I or Schedule II to the Bank Act (Canada) represents and warrants to the Borrower, each of the other Lenders and the Agent, which representation and warranty shall survive the execution of this Agreement, that either:

but upon the occurrence of an Event of Default specified in Sections 9.1(c) or 9.1(d), 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.

9.3 Waiver of Default

Any single or partial exercise by any Lender, the Agent or by the Agent on behalf of 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 any Lender, the Agent or by the Agent on behalf of 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.

9.4 Application of Payments Following Demand and Acceleration

Except as otherwise agreed to by all the Lenders in their sole discretion, any sum received by the Agent at any time after delivery of an Acceleration Notice or the occurrence of an Event of Default specified in Sections 9.1(c) or 9.1(d), which the Agent is obliged to apply in or towards satisfaction of sums due from the Borrower hereunder shall be applied by the Agent among the Lenders and the Agent in accordance with amounts owed to the Lenders and the Agent in respect of each category of amounts set forth below, each such application to be made in the following order with the balance remaining after application in respect of each category to be applied to the next succeeding category:

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; 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 therein contained shall not be deemed to be a waiver of or to alter, affect or prejudice any other right or remedy or other rights or remedies to which the Agent or such Lender or any of the other Lenders 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 therein contained, and any indulgence granted thereby, shall be deemed not to be a waiver of any subsequent default. The Agent, if so required by the Majority Lenders, shall, 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;

occurrence and during the continuance of an Event of Default and from time to time thereafter for so long as such Event of Default is continuing without prior notice to the Borrower or to any other person, any such prior 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, including, without limitation, contingent obligations of the Lenders in respect of unmatured Bankers' Acceptances, provided demand for payment to the extent required hereunder has been made.

Upon the occurrence of an Event of Default and for so long as such Event of Default is continuing or upon receipt of cash cover by the Agent pursuant to Section 4.2 and in addition to any other rights or remedies of the Lenders hereunder but subject to Section 3.15 with respect to Letters of Credit, 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 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 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.

9.8 Lenders May Perform Covenants

If an Event of Default has occurred and is continuing and the Borrower fails 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, without 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 the Lenders on a Pro-Rata basis. 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 5.7 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

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 Taxes payable in connection with the execution, delivery or enforcement of the Loan Documents) and the initial syndication of the Credit Facilities and all out-of-pocket 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 (other than Excluded Taxes) for which the Lender is not entitled to be indemnified by the Borrower pursuant to Section 6.3, or changes the basis of taxation of payments due to such Lender or increases any existing Tax (in either case other than Excluded Taxes) for which the Lender is not entitled to be indemnified by the Borrower pursuant to Section 6.3, on payments of principal, interest or other amounts payable by the Borrower to such Lender under this Agreement unless, in any such case, such Tax is for the account of the Lender pursuant to Section 12.1;
(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 loans by, 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
(c): imposes on a Lender any other condition of general application which applies to this Agreement;

and the result of (a), (b) or (c) is, in the determination of such Lender acting reasonably and in good faith, to increase the cost to such Lender or to reduce the income or return (including, without limitation, return on capital) which is receivable by such Lender in respect of a Borrowing or standby fees payable pursuant to Section 5.8, such Lender shall promptly notify the Agent. The Agent shall promptly notify the Borrower in writing 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 later of:

(i): the next Libor Interest Date in the case of a Libor Loan, on the next date on which standby fees are payable under Section 5.8 in the case of standby fees and on the next Interest Date in any other case (and each such successive date, if applicable); and
(ii): three (3) Business Days after receipt of such notice.

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 on which the Agent, on behalf of such Lender, gives written notice to the Borrower that such Additional Compensation is so accruing or if such Lender is not generally collecting amounts which are the equivalent to Additional Compensation from other borrowers in similar circumstances to the Borrower where it is contractually entitled to do so. A certificate of an officer of such Lender setting forth the amount of the Additional Compensation must be submitted by the Agent to the Borrower and shall be prima facie evidence, in the absence of manifest error, of the amount of the Additional Compensation and shall set forth in reasonable detail the calculation of Additional Compensation being claimed and describe in reasonable detail the basis for such Additional Compensation. The Lender shall (where appropriate) use reasonable averaging and attribution methods in determining the amount of Additional Compensation to be paid by the Borrower under this Section 10.2.

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, after the date hereof, the introduction 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 (including, without limitation, the U.S. Economic Sanctions), makes it unlawful, or prohibited for a Lender (in its opinion acting reasonably and in good faith) to make, to fund or to maintain the Borrowings or a portion of the Borrowings or to perform its obligations under this Agreement, the Lender may, by written notice to the Borrower through the Agent terminate its obligations under this Agreement to make such Borrowings or perform such obligations and the Borrower shall prepay such Borrowings forthwith (or at the end of such period as the Lender in its discretion agrees acting reasonably and in good faith) together with all accrued but unpaid interest and fees as may be applicable to the date of payment or, if any such Lender is not similarly affected with respect to any other basis of Borrowing, convert by notice to the Agent such Borrowings forthwith into any of such other 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:

(i): adequate and fair means do not exist for ascertaining the rate of interest on such Libor Loan;
(ii): 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
(iii): deposits in Canadian Dollars, U.S. Dollars, Euros or Pounds Sterling 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 such Lender 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 Lender, such Libor Loan shall automatically be made as or converted at the end of the Libor Interest Period applicable to such Libor Loan to, as applicable, a U.S. Base Rate Loan in the case of Libor Loans denominated in U.S. Dollars and a Cdn. Prime Loan in the case of Libor Loans denominated in Canadian Dollars, Euros or Pounds Sterling for all purposes under this Agreement 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.

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 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 the 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. 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 prima facie 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 any Environmental Laws or Environmental Liabilities or any default by the Borrower under any provision of any of the Loan Documents (collectively, the "Damages"). This indemnity shall extend to the officers, directors, employees, agents, shareholders and assignees of the Agent and each Lender (each such person, together with the Agent and each Lender, an "Indemnified Party") but shall not apply to Damages arising from or attributable to the wilful misconduct or negligence of any Indemnified Party.

If any claim (in this Section 10.6 referred to as a "Claim") shall be asserted by any person against an Indemnified Party which may give rise to Damages, the Indemnified Party shall promptly notify the Borrower in writing of all particulars of such Claim upon learning of same. The failure to give any such notice, however, shall not affect the Borrower's liability to indemnify the Indemnified Party except to

the extent such failure adversely affects the Borrower's ability to defend, object to, oppose or contest that Claim.

The Borrower shall at all times have the right, if no Event of Default has occurred and is continuing, at its sole expense, to resist, defend and compromise any Claim in the name of the Indemnified Party, by legal counsel acceptable to the Indemnified Party, acting reasonably, who will co-operate in such defence on a reasonable basis; provided that the Indemnified Party shall have the right to participate in the defense or compromise of any Claim by other legal counsel of its choosing if the Indemnified Party, acting reasonably, determines it should so participate; provided that the fees and disbursements of such other counsel shall be for the account of such Indemnified Person unless:

(a): the Borrower and the Indemnified Party shall have mutually agreed to the retention of counsel;
(b): the named parties to such proceedings include the Borrower or a Subsidiary thereof and the Indemnified Party and representation of such parties by the same counsel would be inappropriate due to actual or potential differing interests between them; or
(c): the Borrower has failed to assume the defense of the Claim in a timely manner or to continue to defend the Claim diligently and reasonably throughout the period while such Claim exists.

The Indemnified Party shall not effect any settlement or compromise of any Claim without the written consent of the Borrower which consent shall not be unreasonably withheld or delayed. If the Borrower exercises its rights under this Section 10.6, it shall not compromise or otherwise settle a Claim without the consent of the Indemnified Party suffering such Claim, which consent shall not be unreasonably withheld or delayed. The inability of the Borrower to pay such Claim in full shall constitute a sufficient reason to withhold such consent.

The Borrower shall not, in connection with any Damages in the same jurisdiction, be liable for the fees and expenses of more than one separate legal firm for the Indemnified Parties unless such representation by the same legal counsel would be inappropriate due to actual or potential differing interests or the employment thereof has been specifically authorized by the Borrower in writing and such firm or firms shall be designated in writing by the Agent on behalf of each Indemnified Party.

ARTICLE 11
THE AGENT AND THE LENDERS

11.1 Authorization

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 or to applicable law.

11.2 Responsibility of Agent

The Agent makes no representations or warranties 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 any Designated Subsidiary or the Agent) in connection with the Loan Documents, whether provided before or after the date of this Agreement. The Agent shall not incur any 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 wilful misconduct. The Agent does not assume any responsibility for the payment of any of the Borrowings or other amounts outstanding hereunder by the Borrower.

11.3 Acknowledgement 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 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 any Subsidiary 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 Subsidiary 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 Subsidiary.

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 Accommodations available to the Borrower in excess of such Lender's 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 any of the other Lenders from their respective obligations under any Loan Document to which they are a party or relieve the Borrower or any Subsidiary from its obligations to such other Lenders.

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.

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.

(c): International Credit Facility: If a Lender is an Exempt Lender and is a lender under the International Credit Facility, the Lender will be required to vote the same way under this Agreement and the credit agreement for the International Credit Facility on matters common to both this Agreement and the credit agreement for the International Credit Facility.

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

Other than as specifically provided for herein, the Agent shall within five (5) Business Days deliver to each Lender, at its 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 or provide notice that the same are available electronically, 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(q) 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 any of Sections 3.5, 3.16, 3.18, 3.19 or 4.3. The Agent shall advise each such Lender of the amount, date and details of each Accommodation and of such Lender's participation in each such Accommodation. At or before 11:00 a.m. (Calgary time) on the Drawdown Date, Conversion Date or Rollover Date, as the case may be:

(a)

Loan Participation: each Lender will make its Pro-Rata 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 Pro-Rata 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 the Borrower has not elected to have (or is deemed not to have elected to have) the Lenders purchase such Bankers' Acceptances pursuant to Section 3.7(h), 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 Acceptance Fees payable by the Borrower to such Lender); or
(ii): if the Borrower has elected to have the Lenders purchase such Bankers' Acceptances pursuant to Section 3.7(h), the Discount Proceeds in respect of such Bankers' Acceptances and BA Equivalent Advances (less, in each case, the amount of applicable Acceptance Fees payable by the Borrower to such Lender).

11.9 Arrangements for Repayment of Borrowings

(a): Prior to Acceleration: Prior to the delivery of an Acceleration Notice or the occurrence of an Event of Default specified in Section 9.1(c) or 9.1(d), upon receipt by the Agent of payments from the Borrower on account of principal, interest, fees or any other payment made 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 Event of Default specified in Section 9.1(c) or 9.1(d), 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 a 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 the Borrower shall forthwith on demand 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 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.

11.11 Adjustments Among Lenders

(a): Adjustments to Outstanding Borrowings: Each Lender agrees that, after the delivery of an Acceleration Notice or the occurrence of an Event of Default specified in Section 9.1(c) or 9.1(d), it will at any time and from time to time upon the request of the Agent as required by any Lender purchase portions of the Borrowings made available by the other Lenders which remain outstanding and make any other adjustments which may be necessary or appropriate, in order that the amount of Borrowings made available by each Lender which remain outstanding, as adjusted pursuant to this Section 11.11, will be in the same proportion as the Pro-Rata Share of each such Lender.
(b): Application of Payments: The Lenders agree that, after the delivery of an Acceleration Notice or the occurrence of an Event of Default specified in Section 9.1(c) or 9.1(d), the amount of any repayment made by the Borrower in respect of Borrowings, and the amount of any proceeds from the exercise of any rights or remedies of the Lenders under the Loan Documents, which are to be applied against amounts owing hereunder, will be so applied in a manner so that to the extent possible the amount of Borrowings made available by each Lender which remain outstanding after giving effect to such application will be in the same proportion as the Pro-Rata Share of each such Lender.
(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 any Lender pursuant to this Section 11.11, any amount which a 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 the Borrower to such Lender other than on account of liabilities arising under the Loan Documents; provided that, if at any time a 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 the Borrower in respect of liabilities of the Borrower arising under the Loan Documents, such Lender shall purchase portions of the applicable Borrowings made available by the other Lenders which remain outstanding to the extent required pursuant to Section 11.11(a).
(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, decreases in interest rates, standby fees, Acceptance Fees, LC Fees, Utilization Fees, the Margin, the Standby Fee Rate, decreasing the amount of any payments payable by the Borrower to the Lenders under this Agreement or any waiver of the time of payment of any amounts payable to the Lenders under this Agreement;
(ii): an increase or decrease in the Commitment of any Lender other than as provided for herein;
(iii): an assignment or transfer by the Borrower of any of its rights and obligations under this Agreement other than as provided for herein;
(iv): a change in the definition of "Majority Lenders", "Maturity Date", "Designated Subsidiary", "Term Date", "Term Period" or any other definition to the extent relevant to any of the other 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(v), Section 8.2 or this Section 11.12(a); or
(vii): an Event of Default under Section 9.1(a) or 9.1(b);

shall bind the Lenders only if such waiver or amendment is agreed to in writing by all of the Lenders. In addition, any waiver of or amendment to any provision of the Loan Documents which relates to an increase in the Commitment of any Lender shall bind that Lender only if agreed to in writing by such Lender.

(b): Majority Consent: Subject to Sections 11.12(a) and 11.12(c) 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 Approval: Subject to Section 11.12(a) and except as otherwise provided in the Loan Documents, any determination, consent, approval or other action made by the Agent hereunder pursuant to any provision which states that such action shall or may be taken by the Agent shall bind all of the Lenders.
(d): Agent Consent: Any waiver of or any amendment to any provision of the Loan Documents which relates to the rights or obligations of the Agent in its capacity as Agent shall require the agreement of the Agent thereto.

11.13 Reimbursement of Agent's Expenses

Each Lender agrees that it will indemnify the Agent for its Pro-Rata Share of any and all costs, expenses and disbursements (including, without limitation, those costs and expenses referred to in Section 10.1) which may be incurred or made by the Agent in good faith in connection with the Loan Documents, and agrees that it will, on written demand, reimburse the Agent for any such costs, expenses or disbursements for which the Agent is not promptly reimbursed at any time by the Borrower. The Agent may refrain from exercising any right, power or discretion or taking any action to protect or enforce the rights of any Lender under the Loan Documents until it has been so reimbursed.

11.14 Reliance by Agent on Notices, etc.

The Agent shall be entitled:

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

and the Agent shall assume no responsibility and shall incur no liability to any 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 in all transactions and generally do any banking business with or provide any financial services to the Borrower without having any liability to account to the other Lenders therefor. With

respect to the Agent's Commitment and Pro-Rata Share with respect thereto, the Agent 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

Subject to Section 12.2, the Borrower authorizes the Agent and each Lender to share among each other any information possessed by it regarding the Borrower, any Subsidiary or the Loan Documents. The Agent and each Lender agrees to keep the Loan Documents and all information provided by the Borrower or any Subsidiary confidential and shall not disclose such information to any person whatsoever (other than as provided for herein and other than to employees and professional advisors 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 aggregate of the Commitments of all the Remaining Lenders consent to such removal. Upon any such resignation or removal, the Remaining Lenders shall appoint a successor agent; provided that the Borrower shall provide its written approval of the successor agent (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 Dealing with the Agent

In the absence of 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.

11.19 Indemnity of Agent

Each Lender hereby agrees to indemnify the Agent (to the extent either not reimbursed by the Borrower or not paid for by the Borrower pursuant to Section 5.9), as to its Pro-Rata share 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 wilful misconduct. Without limiting the generality of the foregoing, each Lender agrees to reimburse the Agent promptly upon demand for its Pro-Rata share 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.

ARTICLE 12
SUCCESSORS AND ASSIGNS AND JUDGMENT CURRENCY

12.1 Successors and Assigns

Subject to Section 8.1(x), 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, with the prior consent of the Agent and each Fronting Lender (such consents not to be unreasonably withheld) and upon payment to the Agent (for the benefit of the Agent) of Cdn. $3,500 but without the Borrower's consent, assign in whole or in part their rights and obligations under this Agreement and the other Loan Documents. If no Event of Default has occurred and is continuing, a Lender may, at its sole cost and expense, with the prior consent of the Agent, each Fronting Lender and the Borrower (such consents not to be unreasonably withheld) and upon payment to the Agent (for the benefit of the Agent) of Cdn. $3,500, assign in whole or in part its rights and obligations under this Agreement and the other Loan Documents to another financial institution where such Lender assigns a minimum aggregate amount of its Commitment of at least Cdn. $10,000,000 and in whole multiples of Cdn. $1,000,000 thereafter and would thereafter, where such assignment is for less than its entire Commitment, retain for its own account a Commitment of at least Cdn. $10,000,000. Assignments by an Exempt Lender shall include a concurrent assignment by the Exempt Lender which is a "Lender" under the International Credit Facility of a corresponding portion of its "Commitment" under the International Credit Facility to the assignee. Notwithstanding the foregoing and without the consent of the Borrower or the Agent but subject to the immediately preceding sentence, a Lender may, at any time, assign all or any part of its Commitment to an Affiliate of such Lender provided that any increased cost to the Borrower howsoever arising, including as a result of the residency of such Affiliate, will be the sole obligation 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 Assignment 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 and except in the case of an assignment to an Affiliate where the consent, not to be unreasonably withheld, of the Borrower to a release shall be required, 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 and, for greater certainty, the Borrower shall have no liability to a Permitted Assignee of a Lender pursuant to either Section 6.3(a) or 10.2(a) if such Lender assigns all or any of its Commitment to a Permitted Assignee who is a non-resident of Canada within the meaning of the Income Tax Act (Canada) if such liability would not arise if such Permitted Assignee was not a non-resident of Canada for such purposes. 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 sole account of such Lender and that the selling Lender shall continue to be obligated as a Lender hereunder in all respects notwithstanding any such participation. The selling Lender shall act on behalf of all of its participants in all dealings with the Borrower in respect of the Credit Facilities and no person who acquires a participation shall have any voting or consent rights with respect to any matter requiring the Lender's consent hereunder. 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 and its Subsidiaries.

12.2 Exchange and Confidentiality of Information

(a): each of the Lenders and the Agent may disclose all or any part of the Information if 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 (other than disclosure to governmental regulators conducting examinations of a Lender's loan portfolio) the Lenders and the 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, as the case may be, with the written agreement referred to in Section 12.2(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 the applicable 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 12.2 at all times prior to and, if applicable, after becoming a Permitted Assignee or participant;
(d): 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 to defend any lawsuit commenced by the Borrower 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
(e): 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:

(f): 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 12.2) or which has been made readily available to the public by the Borrower;

(g): which the Agent or any Lender can show was, prior to receipt thereof from the Borrower, lawfully in the Agent's or the 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
(h): 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.

12.3 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.

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 12.3 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.

In order to facilitate the acceptance of Bankers' Acceptances pursuant to the terms of the Credit Agreement (Canada), Petro-Canada (the "Borrower") hereby appoints each Lender (individually, the "Bank"), acting by its duly authorized signatories (the "Attorney") for the time being at the Bank's main branch in Toronto, Ontario or at such other branch designated by the Bank (the "Branch of Account"), the attorney of the Borrower:
