(b) At any time and from time to time prior to the Maturity Date, the Borrower may increase the aggregate amount of the Global Commitments of the Combined Lenders (each such increase, a “Global Commitment Increase”) in an aggregate amount for all such increases of up to U.S.$250,000,000 so long as (i) the Global Administrative Agent, the Canadian Administrative Agent, and the Majority Lenders consent to such requested Global Commitment Increase, which consent shall not be unreasonably withheld, conditioned or delayed; (ii) the aggregate Global Commitments calculated after taking into effect the requested Global Commitment Increase does not exceed U.S.$1,450,000,000; and (iii) each Combined

Lender shall have been offered a pro rata share of such requested Global Commitment Increase, but no Combined Lender shall have its Global Commitment increased without such Combined Lender’s consent; provided, that, the Borrower shall have the right to replace any Non-Consenting Lender pursuant to, and in accordance with, Section 2.19(c). Each Combined Lender shall have the option, but no Combined Lender shall have any obligation, to increase its Global Commitment hereunder in connection with any Global Commitment Increase. If the Borrower desires to effect a Global Commitment Increase, the Borrower and the financial institution(s) that the Borrower proposes to become a Lender hereunder, and, if applicable, the existing Lender(s) that the Borrower proposes to increase its existing Global Commitment shall (subject at all times to the consent of each such financial institution or each such existing Lender, as applicable) execute and deliver to the Global Administrative Agent and the Canadian Administrative Agent a certificate substantially in the form of Exhibit J hereto (an “Additional Lender Certificate”). Upon receipt of such Additional Lender Certificate (A) any such additional Lender shall be deemed to be a party in all respects to this Agreement and the other Loan Documents as of the effective date set forth in such Additional Lender Certificate and (B) upon the effective date set forth in such Additional Lender Certificate, any such Lender party to the Additional Lender Certificate shall purchase a pro rata portion of the outstanding Loans (and participation interests in the Letters of Credit) of each of the current Lenders such that the Lenders (including any additional Lender, if applicable) shall hold their Applicable Percentage of the outstanding Loans (and participation interests).

(c) The Global Commitments shall from time to time be reallocated, and the Commitments shall from time to time be adjusted, by the Global Administrative Agent in accordance with this Section 2.1(c). Upon each delivery by Parent of a Borrowing Base Allocation Notice in accordance with Section 2.8(d)(iii) or (iv) of the U.S. Credit Agreement, or upon an increase of the Global Commitments pursuant to Section 2.1(b), or upon a reduction of the Global Commitments by the Borrower pursuant to Section 2.8, the Global Administrative Agent will reallocate the Global Commitments of the Combined Lenders between this Agreement and the U.S. Credit Agreement in order to establish new Commitments under this Agreement and U.S. Commitments under the U.S. Credit Agreement for the Combined Lenders pursuant to the following guidelines: (i) the Global Commitments of all Combined Lenders will be reallocated in such a manner that the ratio of the aggregate Commitments of all Lenders to the Combined Commitments equals the ratio of the then proposed Allocated Canadian Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) to the then proposed Global Borrowing Base (as

so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement); (ii) the Global Commitments of U.S. Only Lenders shall be allocated such that the U.S. Commitment of each U.S. Only Lender shall be equal to its Global Commitment; (iii) the Global Commitments of the Pro Rata Lenders (and their respective Affiliates, if any, that are U.S. Lenders) shall be reallocated such that (A) if a Pro Rata Lender is both a Lender and a U.S. Lender, (1) the ratio of such Pro Rata Lender’s Commitment to its Global Commitment is equal to the ratio of the then proposed Allocated Canadian Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) to the then proposed Global Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) and (2) the ratio of such Pro Rata Lender’s U.S. Commitment to its Global Commitment is equal to the ratio of the then proposed Allocated U.S. Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) to the then proposed Global Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) and (B) if a Pro Rata Lender is a Lender and has an Affiliate that is a U.S. Lender, (1) the ratio of such Pro Rata Lender’s Commitment to the Global Commitment associated with such Pro Rata Lender and such Affiliate is equal to the ratio of the then proposed Allocated Canadian Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) to the then proposed Global Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) and (2) the ratio of such Affiliate’s U.S. Commitment to the Global Commitment associated with such Pro Rata Lender and such Affiliate is equal to the ratio of the then proposed Allocated U.S. Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement) to the then proposed Global Borrowing Base (as so designated or determined in accordance with Section 2.8 of the U.S. Credit Agreement); (iv) after making the reallocations in clauses (ii) and (iii) above, the Global Administrative Agent shall determine the Flex Portion of the Combined Commitments, the U.S. Flex Portion of the Combined Commitments and the Canadian Flex Portion of the Combined Commitments and shall allocate the Flex Portion of the Combined Commitments, the U.S. Flex Portion of the Combined Commitments and the Canadian Flex Portion of the Combined Commitments among the Flex Lenders such that (A) if a Flex Lender is both a Lender and a U.S. Lender, such Flex Lender shall be allocated (1) its Flex Percentage of the U.S. Flex Portion of the Combined Commitments and (2) its Flex Percentage of the Canadian Flex Portion of the Combined Commitments, and (B) if a Flex Lender is a Lender and has an Affiliate that is a U.S. Lender, (1) such Flex Lender shall be allocated its Flex Percentage of the Canadian Flex Portion of the Combined Commitments and (2) its Affiliate shall be allocated such Affiliate’s Flex Percentage of the U.S. Flex Portion of the Combined Commitments. The Global Administrative Agent shall (x) in the case of a reallocation of the Global Commitments as a result of the delivery of a Borrowing Base Designation Notice, notify the Parent, the Borrower and the Combined Lenders of the reallocated Global Commitments and adjusted Combined Commitments at the same time that it notifies them, pursuant to Section 2.8(d)(iii) or (iv) of the U.S. Credit Agreement, of the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base and (y) in the case of a reallocation of the Global Commitments as a result of an increase or reduction of the Global Commitments, notify the Borrower and the Combined Lenders of the reallocated Global Commitments and adjusted Combined Commitments by the date on which such increase or reduction is to become effective in accordance with the terms of Section 2.1(b) or 2.8. Any U.S. Only Lender may become a Pro Rata Lender or a Flex Lender, and any Pro Rata Lender may become a Flex Lender, in each case by giving the Global Administrative Agent a written notice of its agreement to be designated as such, which notice shall be effective as of the date of the next reallocation of the Global Commitments made pursuant to this clause (c). No Combined Lender may have more than one Designation and no Flex Lender may be designated as a Pro Rata Lender or a U.S. Only Lender and no Pro Rata Lender may be designated as a U.S. Only Lender.

(d) The parties hereto acknowledge that any increase in the Global Commitments pursuant to Section 2.1(b) of the U.S. Credit Agreement or any reduction in the Global Commitments pursuant to Section 2.9 of the U.S. Credit Agreement also constitutes an increase or reduction, as the case may be, of the Global Commitments pursuant to Section 2.1(b) and 2.8 hereof (which increase or reduction hereunder shall take place simultaneously with the increase or reduction, as the case may be, under the U.S. Credit Agreement).

Section 2.2 Loans and Borrowings.

(a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Applicable Percentages. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Subject to Section 2.13 and 2.14, each Borrowing shall be comprised entirely of Canadian Prime Loans, Eurodollar Loans or U.S. Prime Loans as the Borrower may request in accordance herewith or shall be comprised of Bankers’ Acceptances and BA Loans made in accordance with Section 2.21. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) Each Eurodollar Borrowing, Bankers’ Acceptance or BA Loan shall be in an aggregate amount that is an integral multiple of U.S.$1,000,000 and not less than U.S.$3,000,000 (including any continuation or conversion of existing Loans made in connection therewith). At the time that each Canadian Prime Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of C$500,000 and not less than C$500,000 (including any continuation or conversion of existing Loans made in connection therewith); provided that a Canadian Prime Borrowing may be in an aggregate amount that is equal to the Equivalent Amount in Canadian Dollars of the entire Unutilized Commitment, if less. At the time that each U.S. Prime Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of U.S.$500,000 and not less than U.S.$500,000, as applicable (including any continuation or conversion of existing Loans made in connection therewith); provided that a U.S. Prime Borrowing may be in an aggregate amount that is equal to the entire Unutilized Commitment, if less. Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of ten (10) Eurodollar Borrowings, BA Loan Borrowings or Bankers’ Acceptance Borrowings outstanding.

(d) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Eurodollar Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

Section 2.3 Requests for Borrowings. To request a Borrowing, an Authorized Officer of the Borrower shall notify the Global Administrative Agent and the Canadian Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 1:00 p.m., Toronto time, three (3) Business Days before the date of the proposed Borrowing or (b) in the case of a Canadian Prime Borrowing, or U.S. Prime Borrowing, by 10:00 a.m., Toronto time, on the Business Day of the proposed Borrowing or by 1:00 p.m., Toronto time, at least one (1) Business Day before the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Global Administrative Agent and the Canadian Administrative Agent of a written Borrowing Request executed by an Authorized Officer of the Borrower, substantially in the form of Exhibit E-1 or otherwise in a form approved by the Global

Administrative Agent and the Canadian Administrative Agent. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.2:

(i) the aggregate amount of the requested Borrowing (which amount will be in the appropriate Currency as required pursuant to the last sentence of this Section 2.3);

(ii) the date of such Borrowing, which shall be a Business Day;

(iii) whether such Borrowing is to be a Canadian Prime Borrowing, a U.S. Prime Borrowing or a Eurodollar Borrowing;

(iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and

(v) either (A) the wire transfer instructions for the account (together with the account number of such account) of the Borrower maintained with a Lender to which funds are to be disbursed or (B) if to be disbursed to an account other than an account maintained with a Lender, the wire transfer instructions for such account (together with the account number of such account), each in compliance with Section 2.5.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be a Canadian Prime Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Canadian Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan (which shall be made in the appropriate Currency based on the Currency of the Borrowings being requested) to be made as part of the requested Borrowing. Notwithstanding anything herein to the contrary, Canadian Prime Loans and BA Loans may only be denominated in Canadian Dollars and U.S. Prime Loans and Eurodollar Loans may only be denominated in U.S. Dollars.

Section 2.4 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, an Authorized Officer of the Borrower may request the issuance of Letters of Credit for its own account or the account of any Subsidiary (other than a Foreign Subsidiary), in a form reasonably acceptable to the Global Administrative Agent, the Canadian Administrative Agent and the relevant Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, an Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions; Issuance of Letters of Credit. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), an Authorized Officer of

the Borrower shall, prior to 1:00 p.m., Toronto time, at least three (3) Business Days prior to the proposed date of issuance or modification, hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the relevant Issuing Bank) to an Issuing Bank, the Canadian Administrative Agent and the Global Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name of the account party (which shall be the Borrower or a Subsidiary that is not a Foreign Subsidiary), the name and address of the beneficiary thereof and such other information (including, if applicable, the Currency of such Letter of Credit which shall be Canadian Dollars or U.S. Dollars) as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by an Issuing Bank, an Authorized Officer of the Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the aggregate LC Exposure shall not exceed U.S.$50,000,000 and (ii) the total Credit Exposure shall not exceed the lower of (A) the aggregate Commitments of the Lenders then in effect, or (B) the Allocated Canadian Borrowing Base then in effect. On the Business Day on which a Letter of Credit is requested to be issued, unless the Global Administrative Agent, the Canadian Administrative Agent or the relevant Issuing Bank determines that any applicable condition precedent required pursuant to this Agreement has not been satisfied, the relevant Issuing Bank shall issue such Letter of Credit for the account of the Borrower or the account of the applicable Subsidiary, as the case may be, by the end of such Business Day.

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the date one year after the date of the issuance of such Letter of Credit or, in the case of any renewal or extension thereof of any Letter of Credit with an initial one-year tenor, one year after such renewal or extension, provided such date is not beyond the Maturity Date unless, with respect to such Letter of Credit that has an expiration date extending beyond the Maturity Date, the Borrower shall, no later than five (5) days prior to the Maturity Date, deposit in an account with the Global Administrative Agent (and in accordance with the procedure and subject to the same terms as described in clause (i) below), in the name of the Global Administrative Agent and for the benefit of the Lenders as security for the LC Exposure with respect to such Letter of Credit, cash collateral in an amount equal to the LC Exposure with respect to such Letter of Credit so remaining as of the Maturity Date.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the relevant Issuing Bank or the Lenders, such Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Canadian Administrative Agent, for the account of such Issuing Bank in the Currency in which such Letter of Credit is denominated,

such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments or Global Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement in the currency in which such Letter of Credit is denominated by paying to the Canadian Administrative Agent an amount equal to such LC Disbursement not later than 2:00 p.m., Toronto time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 11:00 a.m., Toronto time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 2:00 p.m., Toronto time, on the Business Day immediately following the day that the Borrower receives such notice; provided that the Borrower may, subject to the conditions to Borrowing set forth herein, request in accordance with Section 2.3 that such payment be financed with a Borrowing (it being understood that if such payment is to be financed with a Canadian Prime Borrowing or a U.S. Prime Borrowing, then the Borrower may request and obtain such Loan on the same Business Day as the proposed Borrowing, notwithstanding the advance notice requirements of Section 2.3(b), so long as such request is made by 1:00 p.m., Toronto time) in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Borrowing. If the Borrower fails to make such payment when due (or request a Canadian Prime Borrowing or U.S. Prime Borrowing therefor as provided herein), the Canadian Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Canadian Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.5 with respect to Loans made by such Lender in the appropriate Currency (and Section 2.5 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Canadian Administrative Agent shall promptly pay to such Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Canadian Administrative Agent of any payment from the Borrower pursuant to this paragraph (or promptly following the Canadian Administrative Agent’s receipt from the Lenders of proceeds from a requested Borrowing), the Global Administrative Agent shall distribute such payment to such Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse such Issuing Bank, then to such Lenders and such Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse any Issuing Bank for any LC Disbursement (other than the funding of Canadian Prime Loans or U.S. Prime Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and

irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement or the other Loan Documents, or any term or provision herein or therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein proving to be untrue or inaccurate in any respect, (iii) payment by an Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Agents, the Lenders or any Issuing Bank nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of such Issuing Bank; provided that none of the foregoing shall be construed to excuse such Issuing Bank from liability to the Borrower to the extent of any direct or actual damages (AS OPPOSED TO SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES, CLAIMS IN RESPECT OF WHICH ARE HEREBY WAIVED BY THE BORROWER TO THE EXTENT PERMITTED BY APPLICABLE LAW) suffered by the Borrower that are caused by such Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of an Issuing Bank (as finally determined by a court of competent jurisdiction), such Issuing Bank shall be deemed to have exercised care (REGARDLESS OF WHETHER THE ISSUING BANK HAS BEEN NEGLIGENT) in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, any Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. An Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. Such Issuing Bank shall promptly notify the Canadian Administrative Agent and the Borrower by telephone (confirmed by telecopy attaching a copy of each such document) of such demand for payment and whether such Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse such Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest. If an Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and

including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to Canadian Prime Loans or U.S. Prime Loans, as applicable; provided that, if the Borrower fails to reimburse such LC Disbursement within five (5) days after such reimbursement is due pursuant to paragraph (e) of this Section, then Section 2.12(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of such Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives written notice from the Global Administrative Agent, the Canadian Administrative Agent or the Required Lenders demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Canadian Administrative Agent, in the name of the Canadian Administrative Agent and for the benefit of the Lenders, an amount in cash (in the applicable Currency) equal to the aggregate LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in Section 8.1(g) or (h). The Borrower also shall deposit cash collateral pursuant to this paragraph as and to the extent required by Section 2.10, and any such cash collateral so deposited and held by the Canadian Administrative Agent hereunder shall constitute part of the Global Borrowing Base for purposes of determining compliance with Section 2.10. Each such deposit shall be held by the Canadian Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Canadian Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Subject to the proviso at the end of this sentence, other than any interest, if any, earned on the investment of such deposits, which investments shall be made at the option and reasonable discretion of the Canadian Administrative Agent (provided that it has received sufficient protection and indemnities as it reasonably requests in connection with its investing such cash collateral) and at the Borrower’s risk and expense, such deposits shall not bear interest; provided, that, the Borrower may direct the Canadian Administrative Agent to invest amounts credited to such account, at the Borrower’s risk and expense, in Permitted Investments described in clauses (a), (b), (e) and (f) of the definition of “Permitted Investments” contained in the U.S. Credit Agreement. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Canadian Administrative Agent to reimburse the relevant Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the aggregate LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders holding LC Exposure in the aggregate greater than 50% of the aggregate LC Exposure at such time), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) and, if any, all interest and profits thereon shall be returned to the Borrower within three (3) Business Days after all Events of Default then in existence have been cured or waived. If the Borrower is required to provide an amount of cash collateral hereunder pursuant to Section 2.10, such amount (to the extent not applied as aforesaid) shall be returned to

the Borrower as and to the extent that, after giving effect to such return, the Borrower would remain in compliance with Section 2.10 and no Event of Default shall have occurred and be continuing.

(j) Existing Letters of Credit. Each Letter of Credit (as defined in the Existing Credit Agreement) issued for the Borrower’s own account, or the account of any Subsidiary (as defined in the Existing Credit Agreement), under and pursuant to the terms of the Existing Credit Agreement and that is outstanding as of the Closing Date (each an “Existing Letter of Credit”), is hereby deemed to be a Letter of Credit issued and outstanding under this Agreement as of the Closing Date, and the issuer thereof is hereby deemed to be an Issuing Bank hereunder.

Section 2.5 Funding of Borrowings.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 2:00 p.m. (or 3:00 p.m., in the case of a Canadian Prime Borrowing or U.S. Prime Borrowing requested pursuant to Section 2.4(e)), Toronto time, to the account of the Canadian Administrative Agent most recently designated by it for such purpose by notice to the Lenders, which Loan shall be in the appropriate Currency (based on the relevant Borrowing Request). The Canadian Administrative Agent will make such Loans available to the Borrower by promptly wiring the amounts so received, in like funds, to an account of the Borrower in Canada in accordance with the wiring instructions set forth in the relevant Borrowing Request; provided that Canadian Prime Loans and/or U.S. Prime Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.4(e) shall be remitted by the Canadian Administrative Agent to the applicable Issuing Bank.

(b) Unless the Canadian Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Canadian Administrative Agent such Lender’s share of such Borrowing, the Canadian Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Canadian Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Canadian Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Canadian Administrative Agent, at (i) in the case of such Lender, the greater of (A) the costs incurred by the Canadian Administrative Agent for making such Lender’s share of such Borrowing or (B) a rate determined by the Canadian Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to Loans made in such Borrowing (provided that any such demand made to the Borrower shall be made within three (3) Business Days following disbursement by the Canadian Administrative Agent, or the Canadian Administrative Agent shall be deemed to have waived the right to make such demand for immediate reimbursement from the Borrower and such funded amount shall be, as with respect to the Borrower, deemed to be a

Loan hereunder). If such Lender pays such amount to the Canadian Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

(c) Borrowings, conversion or continuations of Loans, and prepayments of Loans of different Currencies at the same time hereunder shall be deemed to be separate Borrowings, continuations, conversions and prepayments, respectively, one for each Currency.

Section 2.6 Interest Elections.

(a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request (or a Canadian Prime Borrowing if no Type is specified) and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request (or one month if no Interest Period is specified). Thereafter, the Borrower may elect from time to time to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may, subject to the requirements of Section 2.2(c), elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b) To make an election pursuant to this Section, an Authorized Officer of the Borrower shall notify the Global Administrative Agent and the Canadian Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.3 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Global Administrative Agent and the Canadian Administrative Agent of a written Interest Election Request executed by an Authorized Officer of the Borrower, substantially in the form of Exhibit E-2 or otherwise in a form approved by the Global Administrative Agent and the Canadian Administrative Agent.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.2:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be a Canadian Prime Borrowing or a U.S. Prime Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d) Promptly following receipt of an Interest Election Request, the Canadian Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If the Borrower fails to deliver a timely Interest Election Request (or delivers an Interest Election Request that is inconsistent with a telephonic election) with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to a U.S. Prime Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Global Administrative Agent or the Canadian Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as such Event of Default is continuing, (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless the Obligations have been accelerated pursuant to Section 8.3, each Eurodollar Borrowing shall be converted to a U.S. Prime Borrowing at the end of the Interest Period applicable thereto.

Section 2.7 Global Borrowing Base.

(a) Effectiveness. Notwithstanding anything to the contrary in this Agreement, for so long as any of the Combined Commitments are in effect and/or any Combined Obligation is outstanding, the Global Borrowing Base shall be determined in accordance with, and as provided in, Section 2.8 of the U.S. Credit Agreement.

(b) Annual Scheduled Determinations of the Global Borrowing Base. Promptly after January 1st of each calendar year (commencing January 1, 2008), and in any event prior to April 1st of each calendar year, commencing April 1, 2008, the Parent shall furnish to the Global Administrative Agent and the Combined Lenders a Reserve Report in form and substance reasonably satisfactory to the Global Administrative Agent, which Reserve Report shall evaluate as of December 31st of the immediately preceding calendar year the Proved Mineral Interests attributable to the Oil and Gas Properties which the Parent wishes to include in the Global Borrowing Base, and a projection of the rate of production and net operating income with respect thereto, as of such date, together with additional data concerning pricing, hedging, operating costs and quantities of production, and other information and engineering and geological data as the Global Administrative Agent or any Combined Lender may reasonably request. Within 30 days after receipt of such report and information, the Global Administrative Agent shall make an initial determination of the Global Borrowing Base and shall promptly notify the Combined Lenders and the Parent in writing of the Global Administrative Agent’s initial determination of the Global Borrowing Base. The Global Administrative Agent shall make such determination in accordance with its customary practices and standards for oil and gas

loans and in the exercise of its sole discretion. Within fifteen (15) days following their receipt of the proposed amount for the redetermined Global Borrowing Base, (i) the Supermajority Lenders (and with the agreement of the Parent, such agreement to be given in its sole discretion) if the proposed amount is an increase or (ii) the Required Lenders if the proposed amount is a decrease or maintenance, shall approve or reject the Global Administrative Agent’s initial determination of the Global Borrowing Base by written notice to the Global Administrative Agent; provided, however that failure by any Combined Lender to reject in writing the Global Administrative Agent’s determination of the Global Borrowing Base within said fifteen (15) day period shall be deemed an acceptance of such determination by such Combined Lender. If the Supermajority Lenders (and with the agreement of the Parent, such agreement to be given in its sole discretion) or the Required Lenders, as applicable, fail to approve any such determination of the Global Borrowing Base made by the Global Administrative Agent hereunder, then the Global Administrative Agent shall poll the Supermajority Lenders or Required Lenders, as appropriate, and the Global Borrowing Base shall be set at the highest amount on which the Supermajority Lenders (and with the agreement of the Parent, such agreement to be given in its sole discretion) if such number would result in an increase in the Global Borrowing Base, or otherwise, the Required Lenders can agree, it being understood that a Combined Lender is deemed to have agreed to any and all amounts that are lower than the amount actually determined by such Combined Lender to be the appropriate value of the Global Borrowing Base. Upon approval or deemed approval by the Supermajority Lenders and the Parent or the Required Lenders, as applicable, of the Global Borrowing Base, the Global Administrative Agent upon notice thereof shall, by written notice to the Parent and the Combined Lenders, designate the new Global Borrowing Base available to the Parent and the Borrower (each such notice in this Section 2.7(b), a “Global Borrowing Base Designation Notice”). If the Combined Commitments are in effect and/or any Combined Obligations are outstanding, then upon receipt of such Global Borrowing Base Designation Notice, the Parent shall designate the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base to the Global Administrative Agent in accordance with Section 2.7(d). The Parent shall be deemed to have agreed to the Global Borrowing Base as set forth in such Global Borrowing Base Designation Notice unless it informs the Global Administrative Agent in writing of its objection thereto prior to the date it designates the Allocated U.S. Borrowing Base and Allocated Canadian Borrowing Base pursuant to Section 2.7(d) following its receipt of such Global Borrowing Base Designation Notice.

(c) Maximum Credit. The Global Borrowing Base shall represent the maximum amount of credit in the form of loans, letters of credit and bankers’ acceptances (subject to the aggregate Combined Commitments and subject to the other provisions hereof or of the U.S. Credit Agreement) that the Combined Lenders will extend to the Borrower or the Parent pursuant to the Combined Loan Documents at any one time prior to the Maturity Date.

(d) Allocation of the Global Borrowing Base. For so long as any of the Combined Commitments are in effect and/or any Combined Obligations are outstanding, the Global Borrowing Base shall be comprised of the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base, and allocations between the Allocated U.S. Borrowing Base and Allocated Canadian Borrowing Base shall be made in accordance with this Section 2.7(d).

(i) The “Allocated U.S. Borrowing Base” means, as of any date, the amount in U.S. Dollars designated or determined as such from time to time (A) by the Parent pursuant to a Borrowing Base Allocation Notice delivered in accordance with Section 2.7(d)(iii) of this Agreement or (B) in accordance with the other provisions of this Agreement. As of the date of this Agreement, the initial Allocated U.S. Borrowing Base shall be U.S.$550,000,000.

(ii) The “Allocated Canadian Borrowing Base” means, as of any date, the Equivalent Amount in U.S. Dollars designated as such from time to time (A) by the Parent pursuant to a Borrowing Base Allocation Notice delivered in accordance with Section 2.7(d)(iii) of this Agreement or (B) in accordance with the other provisions of this Agreement. On the date of this Agreement, the initial Allocated Canadian Borrowing Base shall be U.S.$300,000,000.

(iii) Within ten (10) Business Days of receipt of a Global Borrowing Base Designation Notice, the Parent shall specify the allocation of the Global Borrowing Base between the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base by providing a written notice to the Global Administrative Agent of such allocation (each such notice herein a “Borrowing Base Allocation Notice”); provided that (A) the sum of the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base shall at all times be equal to the Global Borrowing Base then in effect and (B) at no time shall the Allocated U.S. Borrowing Base be set at an amount less than U.S.$50,000,000 and at no time shall the Allocated Canadian Borrowing Base be set at an amount less than U.S.$50,000,000 (such minimum amount in respect of the Allocated U.S. Borrowing Base then in effect, the “Minimum Threshold Amount”). In the event that the Parent fails to provide the Global Administrative Agent with a Borrowing Base Allocation Notice required to be delivered upon receipt of a Global Borrowing Base Designation Notice within the period required by this Section 2.7(d)(iii), the Global Borrowing Base will be allocated in the same proportion as existed prior to such redetermination. Promptly upon the allocation of the Global Borrowing Base between the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base in accordance with the procedures set forth above, the Global Administrative Agent shall provide a written notice to the Combined Lenders and the Parent, which written notice shall set forth the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base to be in effect. Any designation of the Allocated U.S. Borrowing Base or the Allocated Canadian Borrowing Base effected pursuant to this Section 2.7(d)(iii) in connection with a determination or redetermination of the Global Borrowing Base shall be effective as of the date of the Global Borrowing Base Designation Notice.

(iv) So long as no Default or Event of Default shall have occurred and be continuing, from time to time but in no event more than (A) four (4) times per Fiscal Year and (B) once every thirty (30) days, upon at least five (5) Business Days prior written notice to the Global Administrative Agent, the Parent may reallocate the Global Borrowing Base between the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base (a “Discretionary Borrowing Base Reallocation”). Promptly upon the allocation of the Global Borrowing Base between the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base in accordance with the procedures set forth in

this clause (iv), the Global Administrative Agent shall provide a written notice to the Combined Lenders and the Parent, which written notice shall set forth the Allocated U.S. Borrowing Base and the Allocated Canadian Borrowing Base to be in effect. Any designation of the Allocated U.S. Borrowing Base or the Allocated Canadian Borrowing Base effected pursuant to this Section 2.7(d)(iv) in connection with a Discretionary Borrowing Base Reallocation, shall (1) be effective five (5) Business Days following the date the Global Administrative Agent receives the Borrowing Base Allocation Notice or the date indicated for such effectiveness in the Borrowing Base Allocation Notice, whichever is later and (2) be subject to the Minimum Threshold Amount described in clause (iii) above.

(e) Discretionary Redetermination of the Global Borrowing Base. Each of (i) the Parent or (ii) (A) the Global Administrative Agent or (B) the Required Lenders, shall have the right to request in writing a redetermination of the Global Borrowing Base, in its or their sole discretion at any time and from time to time, provided, that clause (i) and clause (ii) may each be the basis of an unscheduled redetermination not more often than one (1) time during any calendar year, regardless, in the case of clause (ii), of which Person makes such request. If any Person shall request a discretionary redetermination of the Global Borrowing Base pursuant to the provisions of this Section 2.7(e), the Parent shall, upon receipt of a request therefor from the Global Administrative Agent, deliver to the Global Administrative Agent, by the date reasonably requested by the Global Administrative Agent (or, in the event of an unscheduled redetermination requested by the Parent, by the date mutually agreed upon by the Parent and the Global Administrative Agent), a Reserve Report dated as of the date requested in such notice and such updated engineering, production, operating and other data as the Global Administrative Agent or any other Combined Lender may reasonably request; provided, that, such Reserve Report may, in the discretion of the Parent, be (1) a new Reserve Report, (2) the Reserve Report delivered in connection with the immediately preceding redetermination (whether scheduled or unscheduled) of the Global Borrowing Base and the U.S. Borrowing Base, and/or (3) an update of such Reserve Report described in subclause (2); provided, further that, in connection with any request for an unscheduled redetermination pursuant to clause (ii) above, the Reserve Report shall cover additional Oil and Gas Properties of the Parent and its Subsidiaries as the Required Lenders may reasonably request. The Supermajority Lenders (and with the agreement of the Parent, such agreement to be given in its sole discretion) if such number would result in an increase in the Global Borrowing Base or otherwise, the Required Lenders shall approve and designate the new Global Borrowing Base in accordance with the procedures and standards described in Section 2.7(b) and the Parent shall provide a Borrowing Base Allocation Notice to the Global Administrative Agent in accordance with Section 2.7(d)(iii); provided that in the event that the Parent fails to provide such Borrowing Base Allocation Notice, the Global Borrowing Base shall be allocated between the Allocated U.S. Borrowing Base and Allocated Canadian Borrowing Base in accordance with Section 2.7(d)(iii).

(f) General Provisions With Respect to the Global Borrowing Base. The determination of the Global Borrowing Base shall be made by the Global Administrative Agent and the Supermajority Lenders or Required Lenders, as applicable, taking into consideration the estimated value of the Oil and Gas Properties owned by the Parent and its Subsidiaries as reflected in the most recent Reserve Report delivered hereunder and any other relevant information obtained by or delivered to the Global Administrative Agent or any other Combined

Lender, all in accordance with the other provisions of this Section 2.7 in accordance with their customary practices for oil and gas loans as in effect from time to time. It is understood by the parties hereto that, unless otherwise approved by the Supermajority Lenders pursuant to, and in accordance with, the other provisions of this Section 2.7, the Combined Lenders shall have no commitment or obligation whatsoever to increase the Global Borrowing Base to any amount in excess of U.S.$850,000,000, and nothing herein contained shall be construed to be a commitment by the Combined Lenders to so increase the Global Borrowing Base except to the extent so approved. The Global Borrowing Base (i) may be redetermined pursuant to Section 2.7(b) (annual) and Section 2.7(e) (unscheduled), (ii) subject to the rights of the Parent and the applicable Subsidiaries contained in Section 2.7(g), may be adjusted from time to time to give effect to the occurrence of Casualty Events under Section 2.7(g), and (iii) may be reduced by an amount not greater than the applicable Debt Issuance Reduction Amount pursuant to Section 2.7(h) in connection with the issuance of any Permitted Senior Notes Debt. In connection with any redetermination, adjustment or reduction pursuant to any of the foregoing, if the Global Administrative Agent determines that a Global Borrowing Base Deficiency exists, the Global Administrative Agent shall give written notice thereof to the Parent and the Borrower and the date such notice is received shall be the “Deficiency Notification Date”.

(g) Casualty Event. In the event that a Casualty Event has occurred with respect to any Borrowing Base Property, to the extent that the Net Cash Proceeds received by the Parent or any of its Subsidiaries with respect to such Casualty Event (together with all other Net Cash Proceeds received during such calendar year) exceeds 5% of the Global Borrowing Base and have not been applied or budgeted to be applied by the Parent or any such Subsidiary to repair, restore or replace the Property affected by such Casualty Event within 180 days after the receipt thereof, which actions the Parent or such Subsidiary shall hereby be permitted to take, the Global Administrative Agent, at the request of the Required Lenders, shall have the right to reduce the Global Borrowing Base, in its reasonable discretion based on its review of such Casualty Event, by the value of the Property so affected by such Casualty Event as set forth in the most recent Reserve Report; provided that, if an Event of Default has occurred and is continuing, (i) such repair, restoration or replacement may occur only with the written consent of the Global Administrative Agent, (ii) the Global Administrative Agent may, at the request of the Required Lenders, reduce the Global Borrowing Base in the manner set forth above without regard to the 180 day period referenced above and (iii) such Net Cash Proceeds shall be applied in accordance with Section 2.10 to the extent required thereby. The Global Administrative Agent shall provide notice to the Borrower, Parent and the Combined Lenders of the reduction in the Global Borrowing Base, which reduction shall be effective as of the date of such notice.

(h) Issuance of Other Indebtedness. In the event of the issuance of any Permitted Senior Notes Debt permitted pursuant to Section 7.1(o), the Global Administrative Agent and the Required Lenders shall have the option, on not more than one occasion in connection with each such issuance, to reduce the Global Borrowing Base by an amount agreed to by the Required Lenders, which reduction amount shall not be greater than the applicable Debt Issuance Reduction Amount calculated with respect to such Permitted Senior Notes Debt then most recently issued; provided, that, (i) in the event the Required Lenders are unable to agree upon any such reduction amount provided for in this Section 2.7(h) within thirty (30) days of the issuance of any such

Permitted Senior Notes Debt, the Global Borrowing Base shall reduce by an amount equal to the applicable Debt Issuance Reduction Amount calculated with respect to such Permitted Senior Notes Debt then most recently issued, and (ii) notwithstanding the foregoing or anything to the contrary contained in any Combined Loan Document, if and only to the extent the Parent uses any of the proceeds of the issuance of any Permitted Senior Notes Debt to contemporaneously refinance or replace any of the Existing Subordinate Debt and/or any other Permitted Senior Notes Debt in accordance with the last sentence of Section 7.14 of the U.S. Credit Agreement, then the provisions of this Section 2.7(h) shall not apply, and the Global Borrowing Base shall not be reduced pursuant to the provisions of this Section 2.7(h), in each case only to the extent such proceeds are so used. In connection with any such reduction, the Global Administrative Agent shall promptly provide written notice to the Parent, the Borrower and the Combined Lenders of the reduction of the Global Borrowing Base. Upon the approval of the Required Lenders of such reduction amount, or, alternatively, upon any reduction by an amount equal to the Debt Issuance Reduction Amount, and the delivery of written notice thereof to the Parent and the Borrower, the Global Borrowing Base shall be reduced as of the date such notice is delivered or such later date as specified in such notice. Notwithstanding anything to the contrary in the Combined Loan Documents, (A) the language of the proviso of Section 2.10(b)(i) of this Agreement shall not apply to any Global Borrowing Base Deficiency resulting from the application of this Section 2.7(h) and (B) the application of this Section 2.7(h) shall never result in an increase in the Global Borrowing Base.

Section 2.8 Termination and Reduction of Global Commitments and Commitments; Extension of Maturity Date.

(a) Unless previously terminated, the Global Commitments and the Commitments shall terminate on the Maturity Date.

(b) An Authorized Officer of the Parent may at any time terminate, or from time to time reduce, without premium or penalty, the Global Commitments; provided that (i) each reduction of the Global Commitments shall be in an amount that is an integral multiple of U.S.$1,000,000 and not less than U.S.$3,000,000 and (ii) the Parent shall not terminate or reduce the Global Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10 and after giving effect to a reallocation of the Global Commitments and adjustment of the Commitments pursuant to Section 2.1(c), the aggregate Credit Exposure of the Lenders would exceed the aggregate Commitments of the Lenders.

(c) An Authorized Officer of the Parent shall notify the Global Administrative Agent of any election to terminate or reduce the Global Commitments under paragraph (b) of this Section at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any such notice, the Global Administrative Agent shall advise the Combined Lenders of the contents thereof and reallocate the Global Commitments and adjust the Commitments in accordance with Section 2.1(c). Each notice delivered by an Authorized Officer of the Parent pursuant to this Section shall be irrevocable; provided that a notice of termination of the Global Commitments delivered by an Authorized Officer of the Parent may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Parent (by notice to the Global Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Except as provided in the immediately preceding sentence, any termination or reduction of the Global Commitments shall be permanent

and may not be reinstated except pursuant to, and in accordance with, Section 2.1(b). Each reduction of the Global Commitments shall reduce the Global Commitments of the Combined Lenders on a pro rata basis and result in adjustments to the Commitments of the Lenders in accordance with Section 2.1(c).

(d) The Parent and the Borrower will not terminate, or permit to expire, all of the Global Commitments and Commitments under this Agreement prior to (i) the expiration or termination of the U.S. Commitments and (ii) the payment and performance in full of all U.S. Obligations.

(e) The Borrower may, by notice to the Global Administrative Agent (which shall promptly deliver a copy to each of the Lenders) given not less than 90 days and not more than 120 days, prior to the Maturity Date at any time in effect, and, subject to the proviso below, on not more than two occasions, request that the Lenders extend the Maturity Date for an additional period of not more than one year as specified in such notice; provided, that, the Borrower may, in lieu of the foregoing and not in addition thereto, by notice to the Global Administrative Agent in accordance with the foregoing provisions of this clause (e), on not more than one occasion, request that the Lenders extend the Maturity Date for an additional period of not more than two years as specified in such notice. Each Lender shall, by notice to the Borrower and the Global Administrative Agent given not later than fifteen (15) days following receipt of the Borrower’s request, advise the Borrower and the Global Administrative Agent whether or not it agrees to such extension. The Global Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses. Any Lender that has not so advised the Borrower and the Global Administrative Agent by such day shall be deemed to have declined to agree to such extension. If the Borrower shall have requested, and if each Lender shall have agreed to, an extension of the Maturity Date, then the Maturity Date shall be extended for the additional period specified in the Borrower’s request in accordance with the terms above, and the Global Administrative Agent shall promptly notify the Borrower and the Lenders of the extension of the Maturity Date, whereupon the Maturity Date shall be extended, effective as of the Maturity Date in effect immediately prior to such extension, without the necessity for any further action; provided that, the Borrower shall (i) execute and deliver, or cause to be executed and delivered, any and all documents which may be reasonably required by the Global Administrative Agent in connection with such extension to evidence such extension and new Maturity Date, and (ii) pay to the Global Administrative Agent, for the account of each Lender, an extension fee in such amount as shall be agreed upon by the Borrower and the Global Administrative Agent based on the then prevailing market rate for similar extensions of comparable credit facilities. THE DECISION TO AGREE OR WITHHOLD AGREEMENT TO ANY EXTENSION OF THE MATURITY DATE HEREUNDER SHALL BE AT THE SOLE DISCRETION OF EACH LENDER. Notwithstanding the foregoing provisions of this paragraph, (A) the Maturity Date may not be extended to a date later than February 9, 2014 pursuant to this clause (e), (B) the effectiveness of any such extension shall be subject to (1) the absence of any Default, Event of Default or Global Borrowing Base Deficiency as of the date of such extension and request therefor, (2) the absence of any material and adverse effect on the ability of any Loan Party to fully, completely and timely pay its obligations under this Agreement as of the date of such extension and request therefor, (3) the accuracy, in all material respects, of the representations and warranties of each Loan Party set forth in the Loan Documents to which it is a party as of the date of such extension and request therefor (or, if

stated to have been made expressly as of an earlier date, the accuracy, in all material respects, as of such date), and (4) a corresponding extension of the “Maturity Date” (as defined in the U.S. Credit Agreement) in accordance with the terms of Section 2.9(e) of the U.S. Credit Agreement, (C) the Borrower shall have the right, pursuant to, and subject to the terms of, Section 2.19(c), to replace any Non-Consenting Lender that has declined to agree to any requested extension of the Maturity Date with a Lender or other financial institution that will agree to such extension of the Maturity Date, (D) the Borrower shall have the right, at any time prior to the Maturity Date then in effect, to withdraw its request for an extension under this clause (e) by notice to the Global Administrative Agent (which shall promptly deliver a notice to each Lender), in which case the Maturity Date will not be so extended, and (E) the Borrower shall have the right, at any time prior to the Maturity Date then in effect, to withdraw its request for an extension of the Maturity Date for an additional period of two (2) years and, in lieu thereof, request an extension of the Maturity Date for an additional period of one year, by providing notice to the Global Administrative Agent (which shall promptly deliver a notice to each Lender), in which case (1) the Maturity Date will be extended for one year in the event the Lenders have previously agreed to a two year extension pursuant to the Borrower’s request and in accordance with this Section 2.8(e), or (2) in the event any Lender has not previously agreed to a two year extension pursuant to the Borrower’s request and in accordance with this Section 2.8(e), any such Lender shall, by notice to the Borrower and the Global Administrative Agent given not later than fifteen (15) days following receipt of the Borrower’s request pursuant to this clause (E), advise the Borrower and the Global Administrative Agent whether or not it agrees to such one year extension (and the Global Administrative Agent shall promptly notify the Borrower and the Lenders of the Lenders’ responses), and any Lender that has not so advised the Borrower and the Global Administrative Agent by such day shall be deemed to have declined to agree to such one year extension; provided that, and notwithstanding anything to the contrary contained herein, the Borrower shall not have the right provided in this clause (E) in the event that its original request for an extension of two years was not approved by the Lenders pursuant to the terms of this Section 2.8(e) and the Borrower’s alternative request pursuant to this clause (E) is made (or would be made) by notice to the Global Administrative Agent given less than 45 days prior to the Maturity Date.

Section 2.9 Repayment of Loans; Evidence of Indebtedness.

(a) The Borrower hereby unconditionally promises to pay to the Canadian Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan of such Lender on the Maturity Date.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the Obligations of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Canadian Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Canadian Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to paragraphs (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Canadian Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(e) Any Lender may request that Loans made by it be evidenced by one or more promissory notes. In such event, the Borrower shall prepare, execute and deliver to such Lender promissory notes payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns and in substantially the form of Exhibit A). Thereafter, the Loans evidenced by such promissory notes and interest thereon shall at all times (including after assignment pursuant to Section 10.4) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if any such promissory note is a registered note, to such payee and its registered assigns).

Section 2.10 Prepayment of Loans.

(a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, without premium or penalty except as expressly provided in this Agreement, subject to the requirements of Section 2.10(d). The Borrower shall not be permitted to prepay any Bankers’ Acceptance or BA Loans at any time.

(b) Subject to clause (c) below, the Borrower shall be required to prepay the Loans hereunder and “Loans” under the U.S. Credit Agreement in accordance with the following, to the extent the U.S. Borrower does not otherwise make such prepayment in accordance with the U.S. Credit Agreement:

(i) Upon the occurrence of a Global Borrowing Base Deficiency resulting from a redetermination or reduction of the Global Borrowing Base (other than pursuant to Section 2.7(h)), the Borrower will prepay, or cause to be prepaid, Loans in an aggregate principal amount equal to such deficiency, together, in each case, with unpaid interest accrued thereon to the date of such prepayment and, if after prepaying all of such Loans (other than Bankers’ Acceptances), a Global Borrowing Base Deficiency remains as a result of a BA Exposure, pay to the Canadian Administrative Agent an amount equal to such remaining Global Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.21, and, if after prepaying all of the Combined Loans (other than Bankers’ Acceptances) and providing cash collateral for all Bankers’ Acceptances pursuant to this Section, a Global Borrowing Base Deficiency remains as a result of an LC Exposure, pay to the Canadian Administrative Agent an amount equal to such remaining Global Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.4(i); provided however, that if the Global Borrowing Base Deficiency is the result of a Scheduled Redetermination or a redetermination of the Global Borrowing Base pursuant to Section 2.7(e)(ii) or as a result of any other event directly brought about by the actions of any of the Global Administrative Agent, the Canadian Administrative Agent, the Combined Lenders, the Supermajority Lenders or the Required Lenders (other than an acceleration of the Obligations, reduction, reallocation, adjustment or termination of the Global Commitments or the “Global Commitments” (as defined in the U.S. Credit

Agreement) or the Commitments or U.S. Commitments or an exercise of rights under Article VIII or Article VIII of the U.S. Credit Agreement or any other enforcement of rights or remedies under the Combined Loan Documents), then the Borrower shall, at its option, either (A) make (or cause to be made) a single prepayment of principal and/or deposit of cash collateral in an amount equal to such deficiency within thirty (30) days following the Deficiency Notification Date with respect to such deficiency, (B) make (or cause to be made) six consecutive mandatory prepayments of principal each of which shall be in an amount equal to one-sixth (1/6^th) of the amount of such Global Borrowing Base Deficiency commencing on the first Monthly Date (provided such date is at least thirty (30) days following the Deficiency Notification Date, otherwise commencing on the immediately following Monthly Date) following the Deficiency Notification Date and continuing on each Monthly Date thereafter, (C) within ninety (90) days following the Deficiency Notification Date with respect to such deficiency, submit (and pledge as Collateral) additional Oil and Gas Properties owned by the Parent or any of its Subsidiaries for consideration in connection with the determination of the Global Borrowing Base which the Global Administrative Agent and the Required Lenders deem sufficient in their sole discretion to eliminate such Global Borrowing Base Deficiency, or (D) within ninety (90) days following the Deficiency Notification Date with respect to such deficiency, eliminate such Global Borrowing Base Deficiency through a combination of prepayments and submission of additional Oil and Gas Properties as set forth in clauses (A) and (C) above.

(v) Upon the occurrence of a Global Borrowing Base Deficiency resulting from a Casualty Event pursuant to Section 2.7(g) (subject to the Borrower’s and the applicable Subsidiaries’ rights contained in Section 2.7(g)), the Borrower will utilize the Net Cash Proceeds of such Casualty Event to take the action described under clause (i) above (except that prepayments shall first be made in respect of Loans made pursuant to this Agreement); provided that if a prepayment or deposit is required under this clause (v), then the Borrower shall be obligated to make (or cause to be made) such prepayment and/or deposit of cash collateral within sixty (60) days following the Deficiency Notification Date with respect to such deficiency.

(vi) Upon the occurrence of a Global Borrowing Base Deficiency resulting from the issuance of any Permitted Senior Notes Debt pursuant to Section 2.7(h), the Borrower will prepay, or cause to be prepaid, within thirty (30) days following the Deficiency Notification Date with respect to such deficiency, Loans in an aggregate principal amount equal to such deficiency, together, in each case, with unpaid interest accrued thereon to the date of such prepayment and, if after prepaying all of such Loans (other than Bankers’ Acceptances), a Global Borrowing Base Deficiency remains as a result of a BA Exposure, pay to the Canadian Administrative Agent an amount equal to such remaining Global Borrowing Base Deficiency to be held as cash collateral as

provided in Section 2.21, and, if after prepaying all of the Combined Loans (other than Bankers’ Acceptances) and providing cash collateral for all Bankers’ Acceptances pursuant to this Section, a Global Borrowing Base Deficiency remains as a result of an LC Exposure, pay to the Canadian Administrative Agent an amount equal to such remaining Global Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.4(i).

(vii) Upon the occurrence of a Global Borrowing Base Deficiency not resulting from a reason described in clauses (i), (v) or (vi) above, the Borrower will prepay within sixty (60) days the Loans (other than Bankers’ Acceptances) in an aggregate principal amount equal to such Global Borrowing Base Deficiency together, in each case, with unpaid interest thereon accrued to the date of such prepayment and, if after prepaying all such Loans (other than Bankers’ Acceptances), a Global Borrowing Base Deficiency remains as a result of an LC Exposure, pay to the Global Administrative Agent an amount equal to such remaining Global Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.4(i).

(c) Notwithstanding any other provision of this Section 2.10, if at any time the Credit Exposure of any Lender exceeds its Commitment (including, without limitation, as a result of a reallocation of its Global Commitment and adjustment of its Commitment pursuant to Section 2.1(c)), the Borrower will forthwith prepay the Loans (other than Bankers’ Acceptances) of such Lender in an aggregate principal amount equal to such excess, together with interest on the principal amount paid accrued to the date of such prepayment, and if any excess remains after prepaying all of such Loans as a result of BA Exposure, pay to the Canadian Administrative Agent an amount equal to such remaining excess to be held as cash collateral as provided in Section 2.21, and, if after prepaying all of the Combined Loans (other than Bankers’ Acceptances) and providing cash collateral for all Bankers’ Acceptances pursuant to Section 2.21, any excess remains as a result of an LC Exposure of such Lender, pay to the Canadian Administrative Agent an amount equal to such remaining excess to be held as cash collateral for such Lender as provided in Section 2.4(i). The Borrower shall make prepayments pursuant to this clause (c) prior to making prepayments pursuant to clause (b) above.

(d) The Borrower shall notify the Global Administrative Agent and the Canadian Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 1:00 p.m., Toronto time, three (3) Business Days before the date of prepayment or (ii) in the case of prepayment of a Canadian Prime Borrowing or U.S. Prime Borrowing, not later than 1:00 p.m., Toronto time, one (1) Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid (which amount shall, in the case of clause (a) above, be in a minimum principal amount of U.S.$1,000,000 and in U.S.$1,000,000 increments in excess thereof); provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Global Commitments as contemplated by Section 2.8, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.8. Promptly following receipt of any such notice relating to a prepayment of a Borrowing, the Canadian Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an

advance of a Borrowing of the same Type as provided in Section 2.2. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.12 and by any other amounts then due under this Agreement (including all amounts due under Section 2.16).

Section 2.11 Fees.

(a) The Borrower agrees to pay to the Global Administrative Agent for the account of each Lender a commitment fee (the “Commitment Fee”), which shall accrue at the Applicable Margin on the daily amount equal to the Applicable Percentage of such Lender of the Unutilized Commitment during the period from and including the Global Effective Date to but excluding the date on which the Global Commitments and Commitments terminate. Accrued Commitment Fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Global Commitments and Commitments terminate, commencing on the first such date to occur after the date of this Agreement; provided that any Commitment Fees accruing after the date on which the Global Commitments and Commitments terminate shall be payable on demand. All Commitment Fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) The Borrower agrees to pay (i) to the Canadian Administrative Agent for the account of each Lender a participation fee with respect to its participation in each Letter of Credit, at a per annum rate equal to the Applicable Margin as interest on Eurodollar Loans on such Lender’s Applicable Percentage of the stated face amount of each such outstanding Letter of Credit during the period from and including the date such Letter of Credit is issued (or, in the case of the Existing Letters of Credit, the Global Effective Date) to but excluding the date such Letter of Credit expires, and (ii) to the relevant Issuing Bank a fronting fee equal to the greater of (A) U.S.$500 and (B) the rate of 0.125% per annum on the Equivalent Amount in U.S. Dollars of the stated face amount of each outstanding Letter of Credit during the period from and including the date such Letter of Credit is issued (or, in the case of the Existing Letters of Credit, the Global Effective Date) to but excluding the date such Letter of Credit expires, as well as any such Issuing Bank’s standard and customary fees with respect to the administration, issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees shall be payable upon the issuance and on each renewal of each Letter of Credit. Any other fees payable to any such Issuing Bank pursuant to this paragraph shall be payable within ten (10) Business Days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days.

(c) The Borrower agrees to pay to the Global Administrative Agent, for the account of each Lender, as applicable, fees, including, without limitation, an upfront fee (the “Upfront Fee”), and, if and when applicable, an extension fee (as provided in Section 2.8(e)), in the amounts and at the times separately agreed upon in writing between the Borrower and the Global Administrative Agent.

(d) Unless otherwise set forth herein, all fees payable hereunder shall be paid on the dates due, in immediately available funds in U.S. Dollars, to the Global Administrative

Agent or the Canadian Administrative Agent (or the relevant Issuing Bank, in the case of fees payable to it), as the case may be, for distribution, in the case of Commitment Fees and participation fees, to the Lenders entitled thereto. Fees paid shall not be refundable under any circumstances absent manifest error (e.g., as a result of a clerical mistake).

Section 2.12 Interest.

(a) Subject to Sections 2.12(f), (g) and (h) and Section 10.13, Loans comprising each Canadian Prime Borrowing shall bear interest at the Canadian Prime Rate plus the Applicable Margin for Canadian Prime Loans, and Loans comprising each U.S. Prime Borrowing shall bear interest at the U.S. Prime Rate plus the Applicable Margin for U.S. Prime Rate Loans.

(b) Subject to Sections 2.12(f), (g) and (h) and Section 10.13, the Loans comprising each Eurodollar Borrowing shall bear interest at the Eurodollar Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin for Eurodollar Loans.

(c) Notwithstanding the foregoing, but subject to Sections 2.12(f), (g) and (h) and Section 10.13, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall until paid or waived in writing bear interest, after as well as before judgment, at a rate per annum (the “Default Rate”) equal to (i) in the case of overdue principal of any Loan, the lesser of (A) the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section plus 2% or (B) the Highest Lawful Rate or (ii) in the case of any other amount, the lesser of (A) the rate applicable to Canadian Prime Loans as provided in paragraph (a) of this Section plus 2% or (B) the Highest Lawful Rate.

(d) Subject to Sections 2.12(f), (g) and (h) and Section 10.13, accrued interest on each Loan (other than a Loan consisting of the acceptance of a Bankers’ Acceptance) shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Global Commitments and Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand of the Canadian Administrative Agent or the Required Lenders, (ii) in the event of any repayment or prepayment of any Loan (whether due to acceleration or otherwise), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e) Subject to Sections 2.12(f), (g) and (h) and Section 10.13, all interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Canadian Prime Rate or the U.S. Prime Rate and interest associated with BA Loans shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). Promptly after the determination of any interest rate provided for herein or any change therein, the Canadian Administrative Agent shall notify the Lenders to which such interest is payable and the Borrower thereof. The applicable Canadian Prime Rate, U.S. Base

Rate or Eurodollar Rate shall be determined by the Canadian Administrative Agent, and such determination shall be conclusive absent manifest error.

(f) To the extent permitted by applicable law, any provision of the Interest Act (Canada) or the Judgment Interest Act (Alberta) which restricts any rate of interest set forth herein shall be inapplicable to this Agreement and is hereby waived by the Borrower.

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

(h) Where, in this Agreement, a rate of interest or fees is to be calculated on the basis of a 360-day year, such rate is, for the purpose of the Interest Act (Canada), equivalent to the said rate (i) multiplied by the actual number of days in the one year period beginning on the first day of the period of calculation and (ii) divided by 360.

Section 2.13 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Global Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period;

(b) the Global Administrative Agent is advised by the Required Lenders that the Eurodollar Rate for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period; or

(c) the Global Administrative Agent determines in good faith (which determination shall be conclusive) that by reason of circumstances affecting the interbank dollar market generally, deposits in U.S. Dollars in the London interbank dollar market are not being offered for the applicable Interest Period and in an amount equal to the amount of the Eurodollar Loan requested by the Borrower,

then the Global Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Global Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, which notice the Global Administrative Agent shall give promptly after becoming aware thereof, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing for the affected Interest Period shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as a Eurodollar Loan having the shortest Interest Period which is not unavailable under clauses (a) through (c) of this Section, and if no Interest Period is available, as a U.S. Prime Borrowing.

Section 2.14 Illegality.

(a) Notwithstanding any other provision of this Agreement to the contrary, if (i) by reason of the adoption of any applicable Governmental Rule or any change in any applicable Governmental Rule or in the interpretation or administration thereof by any Governmental Authority or compliance by any Lender with any request or directive (whether or not having the force of law) of any central bank or other Governmental Authority or (ii) circumstances affecting the London interbank dollar market or the position of a Lender therein shall at any time make it unlawful in the sole discretion of a Lender exercised in good faith for such Lender or its Applicable Lending Office to (A) honor its obligation to make Eurodollar Loans either generally or for a particular Interest Period provided for hereunder, or (B) maintain Eurodollar Loans either generally or for a particular Interest Period provided for hereunder, then such Lender shall promptly notify the Borrower thereof in writing through the Global Administrative Agent (who will endeavor to, but not be liable for failing to, provide the Borrower with the basis therefor in reasonable detail) and such Lender’s obligation to make or maintain Eurodollar Loans having an affected Interest Period hereunder shall be suspended until such time as such Lender may again make and maintain Eurodollar Loans having an affected Interest Period (in which case the provisions of Section 2.14(b) hereof shall be applicable). Before giving such notice pursuant to this Section 2.14, such Lender will designate a different available Applicable Lending Office for the affected Eurodollar Loans of such Lender or take such other action as the Borrower may request if such designation or action will avoid the need to suspend such Lender’s obligation to make Eurodollar Loans hereunder and will not, in the sole opinion of such Lender exercised in good faith, be disadvantageous to such Lender (provided, that such Lender shall have no obligation so to designate an Applicable Lending Office for Eurodollar Loans located in the United States of America).

(b) If the obligation of any Lender to make or maintain any Eurodollar Loans shall be suspended pursuant to Section 2.14(a) hereof, all Loans having an affected Interest Period which would otherwise be made by such Lender as Eurodollar Loans shall be made instead as U.S. Prime Loans (and, if such Lender so requests by written notice to the Borrower with a copy to the Global Administrative Agent and the Canadian Administrative Agent, each Eurodollar Loan having an affected Interest Period of such Lender then outstanding shall be automatically converted into a U.S. Prime Loan on the last day of the Interest Period for such Eurodollar Loans unless earlier conversion is required by applicable law) and, to the extent that Eurodollar Loans are so made as (or converted into) U.S. Prime Loans, all payments of principal which would otherwise be applied to such Eurodollar Loans shall be applied instead to such U.S. Prime Loans.

Section 2.15 Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any Issuing Bank; or

(ii) impose on any Lender or any Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan or BA Loan or Bankers’ Acceptance (or of maintaining its obligation to make any such Loan or BA Loan or Bankers’ Acceptance ) or to increase the cost to such Lender or such Issuing Bank of participating in, issuing or maintaining any Letter of Credit or BA Loan or Bankers’ Acceptance, or to reduce the amount of any sum received or receivable by such Lender or such Issuing Bank hereunder (whether of principal, interest or otherwise) with respect to any Eurodollar Loan or any Letter of Credit or any BA Loan or Bankers’ Acceptance, then the Borrower will pay, in accordance with Section 2.15(c), to such Lender or such Issuing Bank such additional amount or amounts as will compensate such Lender or such Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered with respect to any Eurodollar Loan or any Letter of Credit or any BA Loan or Bankers’ Acceptance.

(b) If any Lender or any Issuing Bank determines in good faith that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or such Issuing Bank’s capital or on the capital of such Lender’s or such Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by such Issuing Bank, to a level below that which such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy), then the Borrower will pay, in accordance with Section 2.15(c), to such Lender or such Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company for any such reduction suffered.

(c) A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or such Lender’s or such Issuing Bank’s holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. Except as provided in Section 2.15(d), the Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) Business Days after receipt thereof.

(d) Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased

costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.16 Break Funding Payments. In the event of:

(a) the payment (including prepayment or cash collateralization, as applicable) of any principal of any Eurodollar Loan or BA Loan or Bankers’ Acceptance other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default);

(b) the conversion of any Eurodollar Loan or BA Loan or Bankers’ Acceptance other than on the last day of the Interest Period applicable thereto;

(c) the failure to borrow, convert, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.10 and is revoked in accordance therewith); or

(d) the assignment of any Eurodollar Loan or BA Loan or Bankers’ Acceptance other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.1(b) or 2.19;

then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Eurodollar Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the London interbank market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower, the Global Administrative Agent and the Canadian Administrative Agent and shall be conclusive absent manifest error. Except as provided in the last sentence of this Section 2.16, the Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) Business Days after receipt thereof. Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to this Section for any such loss, cost or expense described in this Section 2.16 incurred more than 180 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Borrower of the circumstance giving rise to such loss, cost or expense described in this Section 2.16 and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor.

Section 2.17 Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), the Global Administrative Agent, the Canadian Administrative Agent, each Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law; provided that if a Lender has breached or is in breach of its representations, warranties, covenants and obligations under Section 2.17(e), then the Borrower shall have no obligations under clause (i) of this Section 2.17(a) with respect to payments made or to be made to such Lender where Indemnified Taxes and/or Other Taxes arise in respect of such payments as a consequence of such Lender’s status as a Foreign Lender.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) THE BORROWER SHALL INDEMNIFY THE GLOBAL ADMINISTRATIVE AGENT, THE CANADIAN ADMINISTRATIVE AGENT, EACH LENDER AND EACH ISSUING BANK, WITHIN TEN (10) BUSINESS DAYS AFTER WRITTEN DEMAND THEREFOR, FOR THE FULL AMOUNT OF ANY INDEMNIFIED TAXES OR OTHER TAXES PAID BY THE GLOBAL ADMINISTRATIVE AGENT, THE CANADIAN ADMINISTRATIVE AGENT, SUCH LENDER OR SUCH ISSUING BANK, AS THE CASE MAY BE, ON OR WITH RESPECT TO ANY PAYMENT BY OR ON ACCOUNT OF ANY OBLIGATION OF THE BORROWER HEREUNDER OR UNDER ANY OTHER LOAN DOCUMENT (INCLUDING INDEMNIFIED TAXES OR OTHER TAXES IMPOSED OR ASSERTED ON OR ATTRIBUTABLE TO AMOUNTS PAYABLE UNDER THIS SECTION) AND ANY PENALTIES, INTEREST AND REASONABLE EXPENSES ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH INDEMNIFIED TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY IMPOSED OR ASSERTED BY THE RELEVANT GOVERNMENTAL AUTHORITY; PROVIDED THAT IF SUCH PAYMENTS OR LIABILITIES ARISE FROM THE LENDER HAVING BREACHED OR BEING IN BREACH OF ITS REPRESENTATIONS, WARRANTIES, COVENANTS AND OBLIGATIONS UNDER SECTION 2.17(e), THEN THE BORROWER SHALL HAVE NO OBLIGATIONS UNDER THIS SECTION 2.17(c) WITH RESPECT TO SUCH PAYMENTS OR LIABILITIES. A CERTIFICATE AS TO THE AMOUNT OF SUCH PAYMENT OR LIABILITY DELIVERED TO THE BORROWER BY A LENDER OR AN ISSUING BANK, OR BY EITHER THE GLOBAL ADMINISTRATIVE AGENT OR THE CANADIAN ADMINISTRATIVE AGENT ON ITS OWN BEHALF OR ON BEHALF OF A LENDER OR AN ISSUING BANK, SHALL BE CONCLUSIVE ABSENT MANIFEST ERROR.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, if available, the Borrower shall deliver to the Global Administrative Agent and the Canadian Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Global Administrative Agent and the Canadian Administrative Agent.

(e) Each Lender represents, warrants and covenants that it is not, and shall not be at any time during the term of this Agreement, a Foreign Lender.

(f) If the Borrower at any time pays an amount under Section 2.17(a), (b) or (c) to any Lender, the Global Administrative Agent, the Canadian Administrative Agent or any Issuing Bank, and such payee receives a refund of or credit for any part of any Indemnified Taxes or Other Taxes which such payee determines in its reasonable judgment is made with respect to such amount paid by the Borrower, such Lender, the Global Administrative Agent, the Canadian Administrative Agent or any Issuing Bank, as the case may be, shall pay to the Borrower the amount of such refund or credit promptly, and in any event within 60 days, following the receipt of such refund or credit by such payee.

(g) If the Borrower pays any amount pursuant to Section 2.17(a) or (c) with respect to any payment to a Lender or, with the prior written consent of such Lender, provides any security therefor pursuant to applicable law, and the Borrower at its expense wishes to contest the eligibility of the relevant Taxes and furnishes to such Lender an opinion of tax counsel satisfactory to such Lender, acting reasonably, to the effect that there exists a reasonable basis for contesting such Taxes, the Borrower may contest such Taxes, provided that:

(i) the Borrower has otherwise complied with this Section 2.17(g);

(ii) the Borrower has delivered to such Lender such additional security or assurances as such Lender may require, acting reasonably, in order to be satisfied that such Lender will not incur any liability by reason of any contestation, including legal fees, disbursements, interest and penalties; and

(iii) the conduct of such proceedings (including the settlement or compromise of same) will remain within the sole discretion of such Lender and will forthwith be abandoned if such Lender so requires, acting reasonably, having regard to its overall tax and related interests.

Section 2.18 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.15, 2.16 or 2.17, or otherwise) prior to the time expressly required hereunder or under such other Loan Document for such payment (or, if no such time is expressly required, prior to 3:00 p.m., Toronto time), on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Canadian Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of

calculating interest thereon. All such payments shall be made to the Canadian Administrative Agent ▇/▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇, ▇.▇., ▇▇▇▇▇▇▇ Branch, BCE Place, ▇▇▇ ▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇ ▇▇▇, with a copy to JPMorgan Chase Bank, N.A., ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇^▇▇ ▇▇▇▇▇, Mail Code: IL1-0010, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, except payments to be made directly to an Issuing Bank as expressly provided herein and payments pursuant to Section 2.15, 2.16, 2.17(c) and 10.3 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made to the Persons specified therein. The Canadian Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. Except as set forth in clause (a) of the definition of “Interest Period”, if any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan Document shall be made in the appropriate Currency as required pursuant to the Loan Documents.

(b) If at any time insufficient funds are received by and available to the Canadian Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied, subject to Section 10.15 and 10.17, (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Canadian Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Canadian Administrative Agent for the account of the Lenders or an Issuing Bank hereunder that the Borrower will not make such payment, the Canadian Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or an Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or each of the Issuing Banks, as the case may be, severally agrees to repay to the Canadian Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Global Administrative Agent, at the greater of the costs incurred by the Canadian Administrative Agent for making such distributed amount and a rate determined by the Canadian Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.4(d) or (e), 2.5(b), 2.18(d) or 10.3(c) then the Canadian Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Canadian Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 2.19 Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different Applicable Lending Office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the reasonable judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.15 or 2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If (i) any Lender asserts that events have occurred suspending its obligation to make or maintain Eurodollar Loans under Section 2.14 when substantially all other Lenders have not also done so, (ii) any Lender requests compensation under Section 2.15, (iii) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, or (iv) any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense, upon notice to such Lender, the Canadian Administrative Agent and the Global Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 10.4), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (A) if the assignee is not a Lender or

a Lender Affiliate, the Borrower shall have received the prior written consent of the Global Administrative Agent and the Canadian Administrative Agent and the Issuing Banks, which consent of such Agents and the Issuing Banks shall not unreasonably be withheld, conditioned or delayed, (B) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts), (C) the assignee and assignor shall have entered into an Assignment and Acceptance, and (D) in the case of any such assignment resulting from a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments.

(c) In addition to the foregoing provisions of Section 2.19(b), the Borrower shall be permitted to replace any Lender who becomes a Non-Consenting Lender (as defined below) with a replacement financial institution (which may be an existing Lender) pursuant to an assignment and delegation, without recourse (in accordance with and subject to the restrictions contained in Section 10.4), of all of such Non-Consenting Lender’s interests, rights and obligations under this Agreement to such replacement financial institution that shall assume such obligations; provided, that (i) if the proposed assignee is not a Lender or a Lender Affiliate, the Borrower shall have received the prior written consent of the Global Administrative Agent and the Issuing Banks, which consent of such Global Administrative Agent and Issuing Banks shall not unreasonably be withheld, conditioned or delayed, (ii) such Non-Consenting Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts), (iii) the assignee and assignor shall have entered into an Assignment and Acceptance, and (iv) the assignee shall consent, at the time of such assignment, to each matter in respect of which such Non-Consenting Lender refused to consent. In the event that, at any time, (A) the Borrower or the Global Administrative Agent has requested the Lenders to (1) increase the Global Commitments in accordance with Section 2.1(b), (2) increase, reaffirm or decrease the Global Borrowing Base in accordance with Section 2.7, or (3) extend the Maturity Date in accordance with Section 2.8(e), (B) the increase, reaffirmation, decrease or extension in question requires the agreement of all Lenders, Supermajority Lenders, Required Lenders or Majority Lenders, as the case may be, in accordance with the terms of Section 2.1(b), Section 2.7 or Section 2.8(e), as applicable, and (C) certain Lenders, but not Majority Lenders (in the case of Section 2.1(b)), the Supermajority Lenders (in the case of Section 2.8(e)), the Required Lenders (in the case of a requested increase in the Global Borrowing Base) or Majority Lenders (in the case of a requested reaffirmation or decrease of the Global Borrowing Base) have agreed to such increase, reaffirmation, decrease or extension, then any Lender, at such time, who does not agree to such increase, reaffirmation, decrease or extension, as applicable, shall be deemed a “Non-Consenting Lender.”

Section 2.20 Currency Conversion and Currency Indemnity.

(a) Payments in Agreed Currency. The Borrower shall make payment relative to any Obligation in the currency (the “Agreed Currency”) in which the Obligation was effected. If any payment is received on account of any Obligation in any currency (the “Other

Currency”) other than the Agreed Currency (whether voluntarily or pursuant to an order or judgment or the enforcement thereof or the realization of any Collateral or the liquidation of the Borrower or otherwise howsoever), such payment shall constitute a discharge of the liability of the Borrower hereunder and under the other Loan Documents in respect of such obligation only to the extent of the amount of the Agreed Currency which the relevant Lender, Issuing Bank or Agent, as the case may be, is able to purchase with the amount of the Other Currency received by it on the Business Day next following such receipt in accordance with its normal procedures and after deducting any costs and expenses of exchange.

(b) Conversion of Agreed Currency into Judgment Currency. If, for the purpose of obtaining or enforcing judgment in any court in any jurisdiction, it becomes necessary to convert into a particular currency (the “Judgment Currency”) any amount due in the Agreed Currency, then the conversion shall be made on the basis of the rate of exchange prevailing on the next Business Day following the date such judgment is given and in any event the Borrower shall be obligated to pay the Agents, Issuing Banks and the Lenders any deficiency in accordance with Section 2.20(c). For the foregoing purposes “rate of exchange” means the rate at which the relevant Lender, Issuing Bank or Agent, as applicable, in accordance with its normal banking procedures is able on the relevant date to purchase the Agreed Currency with the Judgment Currency after deducting costs and expenses of exchange.

(c) Circumstances Giving Rise to Indemnity. To the fullest extent permitted by applicable law, if (i) any Lender, any Issuing Bank or any Agent receives any payment or payments on account of the liability of the Borrower hereunder pursuant to any judgment or order in any Other Currency, and (ii) the amount of the Agreed Currency which the relevant Lender, Issuing Bank or Agent, as applicable, is able to purchase on the Business Day next following such receipt with the proceeds of such payment or payments in accordance with its normal procedures and after deducting any costs and expenses of exchange is less than the amount of the Agreed Currency due in respect of such liability immediately prior to such judgment or order, then the Borrower on demand shall, and the Borrower hereby agrees to, indemnify the Lenders, the Issuing Banks and the Agents from and against any loss, cost or expense arising out of or in connection with such deficiency.

(d) Indemnity Separate Obligation. To the fullest extent permitted by applicable law, the agreement of indemnity provided for in Section 2.20(c) shall constitute an obligation separate and independent from all other obligations contained in this Agreement, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by the Lenders, the Issuing Banks or Agents or any of them from time to time, and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due hereunder or under any judgment or order.

Section 2.21 Bankers’ Acceptances. Subject to the terms and conditions of this Agreement, the Commitments may be utilized, upon the request of the Borrower, in addition to the Loans provided for by Section 2.2 and the issuance of Letters of Credit provided for by Section 2.4, for the acceptance by the Lenders of Bankers’ Acceptances issued by the Borrower, provided that in no event shall (i) the aggregate amount of all Bankers’ Acceptance Liabilities together with the Equivalent Amount in U.S. Dollars of the aggregate Principal Amount of the Loans and the aggregate amount of all LC Exposure exceed the lesser of (A) the aggregate

amount of the Allocated Canadian Borrowing Base then in effect and (B) the aggregate amount of the Commitments of the Lenders, and (ii) any Bankers’ Acceptances have maturities that are not integral multiples of 30 days, nor fewer than 30 days nor more than 180 days, from the BA Acceptance Date (and in no event shall any Bankers’ Acceptances mature on a date after the Maturity Date). Whenever the Borrower is required to furnish a notice to the Canadian Administrative Agent pursuant to the following additional provisions of this Section, it shall give a copy of such notice to the Global Administrative Agent. The following additional provisions shall apply to Bankers’ Acceptances:

(a) In order to facilitate and expedite the issuance and acceptance of Bankers’ Acceptances hereunder, the Borrower agrees to the terms and conditions of the Power of Attorney with respect to the Bankers’ Acceptance attached hereto as Exhibit L.

(b) When the Borrower wishes to make a Borrowing by way of Bankers’ Acceptances, the Borrower shall submit to the Canadian Administrative Agent and the Global Administrative Agent a Bankers’ Acceptance Request by not later than 2:00 p.m., Toronto time, three (3) Business Days’ prior to the BA Acceptance Date. Each Bankers’ Acceptance Request shall be irrevocable and binding on the Borrower. The Borrower shall indemnify each Lender against any loss or expense incurred by such Lender as a result of any failure by the Borrower to fulfill or honor before the date specified as the BA Acceptance Date, the applicable conditions set forth in Article IV, if, as a result of such failure the requested Bankers’ Acceptance is not made on such date. Unless otherwise agreed among the Canadian Administrative Agent, the Global Administrative Agent and the Lenders, the aggregate amount of all Bankers’ Acceptances issued on any BA Acceptance Date hereunder shall be accepted pro rata by all Lenders relative to their respective Applicable Percentage, rounded, upwards or downwards, as the case may be, to the nearest C$100,000. Upon receipt of a Bankers’ Acceptance Request, the Canadian Administrative Agent shall advise each Lender of the contents thereof.

(d) On each day during the period commencing with the issuance by the Borrower of any Bankers’ Acceptance and until such Bankers’ Acceptance Liability shall have been paid by the Borrower, the Commitment of each Accepting Lender that is able to extend credit by way of Bankers’ Acceptances shall be deemed to be utilized for all purposes of this Agreement in an amount equal to the Principal Amount of such Bankers’ Acceptance.

The Commitment of any Lender providing a BA Loan rather than Bankers’ Acceptances shall be deemed utilized during this period in an amount equal to its Applicable Percentage of the total amount of Bankers’ Acceptances and BA Loans in each Bankers’ Acceptance Request.

(e) The Borrower agrees to pay on the BA Maturity Date for each Bankers’ Acceptance, to the Canadian Administrative Agent for account of each Accepting Lender, an amount equal to the Bankers’ Acceptance Liability for such Bankers’ Acceptance.

The Borrower hereby waives presentment for payment of Bankers’ Acceptances by each Accepting Lender and any defense to payment of amounts due to an Accepting Lender in respect

of a Bankers’ Acceptance which might exist by reason of such Bankers’ Acceptance being held at maturity by the Accepting Lender which accepted it and agree not to claim from such Lenders any days of grace for the payment at maturity of Bankers’ Acceptances.

(f) In the event the Borrower fails to notify the Canadian Administrative Agent in writing not later than 2:00 p.m., Toronto time, on the Business Day prior to any BA Maturity Date that the Borrower intends to pay with such Borrower’s own funds the Bankers’ Acceptance Liabilities due on such BA Maturity Date or fails to make such payment, the Borrower shall be deemed, for all purposes to have given the Canadian Administrative Agent notice of a borrowing of a Canadian Prime Loan pursuant to Section 2.3 for an amount equal to the Principal Amount of such Bankers’ Acceptance; provided that:

(i) the BA Maturity Date for such Bankers’ Acceptances shall be considered to be the date of such borrowing;

(ii) the proceeds of such Canadian Prime Loan shall be used to pay the amount of the Bankers’ Acceptance Liability due on such BA Maturity Date;

(iii) if after giving effect to such Canadian Prime Loan, a Global Borrowing Base Deficiency would exist, the Global Administrative Agent shall so advise the Borrower and the Borrower shall comply with the provisions of Section 2.10;

(iv) each Lender which has made a maturing BA Loan (in accordance with Section 2.21(g) hereof) shall continue to extend credit to the Borrower by way of a Canadian Prime Loan (without further advance of funds to the Borrower) in the Principal Amount equal to its Applicable Percentage of the total amount of credit requested to be extended by Bankers’ Acceptances when the BA Loan was made; and

(v) the Canadian Administrative Agent shall promptly and in any event within three (3) Business Days following the BA Maturity Date of such Bankers’ Acceptances, notify the Borrower in writing of the making of such Canadian Prime Loan pursuant to this Section 2.21(f).

(g) If, in the sole judgment of a Lender, such Lender is unable, as a result of applicable law or customary market practice, to extend credit by way of Bankers’ Acceptance in accordance with this Agreement, such Lender shall give written notice to such effect to the Canadian Administrative Agent and the Borrower prior to noon, Toronto time, on the date of the requested credit extension (which notice may, if so stated therein, remain in effect with respect to subsequent requests for extension of credit by way of Bankers’ Acceptance until revoked by notice to the Global Administrative Agent, the Canadian Administrative Agent and the Borrower) and shall make available to the Canadian Administrative Agent, in accordance with Section 2.1 hereof prior to 3:00 p.m., Toronto time, on the date of such requested credit extension a Canadian Dollar loan (a “BA Loan”) in the Principal Amount equal to such Lender’s Applicable Percentage of the total amount of credit requested to be extended by way of Bankers’ Acceptances. The Stamping Fee for that BA Loan shall be calculated on that Principal Amount. On the BA Acceptance Date, the Borrower shall pay each Accepting Lender and each Lender providing a BA Loan a Stamping Fee with respect to such Bankers’ Acceptance and each BA

Loan and each Lender is hereby authorized to deduct such Stamping Fee prior to remitting the BA Net Proceeds to the Canadian Administrative Agent. For each Bankers’ Acceptance or BA Loan, the Stamping Fee payable by the Borrower shall be the product obtained by multiplying: (i) the applicable Bankers’ Acceptance Stamping Fee specified in the definition of Applicable Margin in effect from time to time by (ii) the Principal Amount of that Bankers’ Acceptance or BA Loan; and prorating that product for the number of days in that term from and including the BA Acceptance Date to but not including the BA Maturity Date of that Bankers’ Acceptance or the Interest Period for the BA Loan, as the case may be, on the basis of a year of 365 days. Such BA Loan shall have an Interest Period equal to the term of the Bankers’ Acceptances for which it is a substitute and shall bear interest throughout such Interest Period applicable to that BA Loan at a rate per annum equal to the Bankers’ Acceptance Rate for such Bankers’ Acceptances. On the maturity date of the Bankers’ Acceptances issued concurrently with the advance of the BA Loan, the Borrower shall pay to each Lender which made a BA Loan, in satisfaction of the BA Loan and accrued interest thereon, an amount equal to the Principal Amount of such BA Loan, failing which such Principal Amount shall be converted to a Canadian Prime Loan. The amount of the proceeds of that BA Loan to be disbursed to the Borrower on the BA Acceptance Date shall be the same amount as if that Lender had accepted and purchased its Lender’s Applicable Percentage of the requested Bankers’ Acceptances at a discount from the Principal Amount of that Bankers’ Acceptance calculated at a discount rate per annum equal to the Bankers’ Acceptance Rate for the term of such Bankers’ Acceptances in the same manner that BA Net Proceeds are calculated; provided that the Principal Amount of such BA Loan shall be the same amount as the face amount of the Bankers’ Acceptance which such Lender would have accepted but for this Section 2.21(g).

(h) [Reserved].

(i) (i) If a Lender determines in good faith, which determination shall be final, conclusive and binding upon the Borrower absent manifest error, and notifies the Borrower that, by reason of circumstances affecting the money market:

(ii) there is no market for Bankers’ Acceptances generally or of the requested duration; or

(iii) the demand for Bankers’ Acceptances is insufficient to allow the sale or trading of the Bankers’ Acceptances created and purchased hereunder generally or in connection with the requested duration;

then:

(A) the right of the Borrower to request Bankers’ Acceptances or a BA Loan of the affected duration from that Lender shall be suspended until such Lender determines that the circumstances causing such suspension no longer exist and such Lender so notifies each Borrower; and

(B) any Bankers’ Acceptance Request for an affected duration which is outstanding shall be canceled and the Bankers’ Acceptances or BA Loan requested therein shall not be made and a Bankers’ Acceptance or BA Loan

having the shortest duration available (or if none) a Canadian Prime Loan shall be made in its place.

(j) It is the intention of the Canadian Administrative Agent, the Lenders and the Borrower that, except to the extent a Lender advises otherwise, pursuant to the Depository Bills and Notes Act (“DBNA”), all Bankers’ Acceptances accepted by the Lenders under this Agreement shall be issued in the form of a “depository ▇▇▇▇” (as defined in the DBNA), deposited with the Canadian Depository for Securities Ltd. and made payable to CDS & Co. In order to give effect to the foregoing, the Canadian Administrative Agent shall, subject to the approval of the Borrower and the Lenders, establish and notify the Borrower and the Lenders of any procedure, consistent with the terms of this Agreement and the requirements of the DBNA, as is reasonably necessary to accomplish such intention, including, without limitation:

(i) any instrument held by the Canadian Administrative Agent or a Lender 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 ▇▇▇▇ subject to the Depository Bills and Notes Act (Canada)”;

(ii) any reference to the authentication of the Bankers’ Acceptances will be removed; and

(iii) any reference to “bearer” will be removed and no Bankers’ Acceptance shall be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it.

(k) If any Event of Default shall occur and be continuing on the Business Day that the Borrower receives written notice from the Global Administrative Agent, the Canadian Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with BA Exposure representing greater than 50% of the total BA Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Canadian Administrative Agent, in the name of the Canadian Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the BA Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default described in Section 8.1(g). The Borrower shall also deposit cash collateral pursuant to this paragraph as and to the extent required by Section 2.10, and any such cash collateral so deposited and held by the Canadian Administrative Agent hereunder shall constitute part of the Global Borrowing Base for purposes of determining compliance with Section 2.10. Each such deposit shall be held by the Canadian Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement. The Canadian Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Canadian Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Canadian Administrative Agent for the

satisfaction of the obligations of the Borrower with respect to the BA Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with BA Exposure representing greater than 50% of the total BA Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) and, if any, all interest and profits thereon shall be returned to the Borrower within three (3) Business Days after all Events of Default then in existence have been cured or waived. If the Borrower is required to provide an amount of cash collateral hereunder pursuant to Section 2.10, such amount (to the extent not applied as aforesaid) and, if any, all interest and profits thereon shall be returned to the Borrower, within three (3) Business Days as required by Section 2.10, as and to the extent that, after giving effect to such return, the Borrower would remain in compliance with Section 2.10 and no Event of Default shall have occurred and be continuing.

Without regard to any consent or non-consent provisions of any joint operating agreement covering any of the Borrower’s or such Subsidiary’s (as applicable) Proved Mineral Interests, subject to Immaterial Title Deficiencies and Permitted Encumbrances, the Borrower’s percentage share and/or the percentage share of each Subsidiary executing a Security Document (as applicable) of (a) the costs for each Proved Mineral Interest described in the most recent Reserve Report delivered pursuant hereto is not greater than 105% of the decimal fraction set forth in such Reserve Report, before and after payout, as the case may be, and described therein by the respective designations “working interests,” “WI,” “gross working interest,” “GWI,” or similar terms; provided, that the Borrower or any applicable Subsidiary of the Borrower shall have the right to bear costs disproportionate to the Borrower’s or such Subsidiary’s working interest with respect to any Mineral Interest for a period of time in order to earn an interest in such Mineral Interest from a third party as evidenced by a written agreement, and (b) production from, allocated to, or attributed to each such Proved Mineral Interest is not less than the decimal fraction set forth in such Reserve Report, before and after payout, as the case may be, and described therein by the designations “net revenue interest,” “NRI,” or similar terms.

Each well drilled in respect of each Proved Producing Mineral Interest owned by the Borrower and its Subsidiaries (i) is capable of, and is presently, producing Hydrocarbons in commercially profitable quantities (except to the extent shut-in in accordance with the applicable lease for such Proved Producing Mineral Interest), and after giving effect to the transactions contemplated by this Agreement, the Borrower and each of its Subsidiaries executing a Security Document (as applicable) will be entitled to receive payments on a current basis for its share of production, with no funds in respect of any thereof held in suspense, other than any such funds held in suspense pending delivery of appropriate division orders, and (ii) has been drilled, bottomed, completed, and operated in compliance in all material respects with all applicable Governmental Rules and no such well which is currently producing Hydrocarbons is subject to any penalty in production by reason of such well having produced in excess of its allowable production.

Section 3.7 Licenses, Permits, Etc. Each Loan Party possesses such valid franchises, certificates of convenience and necessity, operating rights, licenses, permits, consents, authorizations, exemptions and orders of Governmental Authorities as are necessary to carry on its business as now conducted and as proposed to be conducted, except to the extent a failure to obtain any such item would not reasonably be expected to have a Material Adverse Effect.

Section 3.8 Compliance with Law. The business and operations of the Loan Parties have been and are being conducted in accordance with all applicable Governmental Rules other than violations of Governmental Rules which would not (either individually or collectively) reasonably be expected to have a Material Adverse Effect.

Section 3.9 Full Disclosure. All information heretofore furnished by each Loan Party to the Global Administrative Agent, the Canadian Administrative Agent or any Lender for purposes of or in connection with this Agreement, any Loan Document or any transaction

contemplated hereby or thereby is, and all such information hereafter furnished by or on behalf of any Loan Party to the Global Administrative Agent, the Canadian Administrative Agent or any Lender will be, true, complete and accurate in every material respect; provided, that any projections and pro forma financial information contained in the materials referenced above are based upon good faith estimates and assumptions believed by management of the applicable Loan Party to be reasonable at the time made, it being recognized by the Agents and Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period covered by such financial information may differ from the projected results set forth therein by a material amount. The Loan Parties have disclosed or have caused to be disclosed to Lenders in writing any and all facts (other than facts of general public knowledge, including those facts contained in the Parent’s filings with the SEC) which would reasonably be expected to have a Material Adverse Effect.

Section 3.10 Organizational Structure; Nature of Business. The Loan Parties are engaged only in the business of acquiring, exploring, developing and operating Mineral Interests and the production, marketing, processing and transporting of Hydrocarbons therefrom and businesses reasonably related or complementary thereto.

Section 3.12 No Default. Neither a Default nor an Event of Default has occurred which is continuing, or will exist after giving effect to the transactions contemplated by this Agreement or the other Loan Documents. Neither the Borrower nor any Subsidiary is in default under, nor has any event or circumstance occurred which, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default under, any Material Agreement to which the Borrower or any Subsidiary is a party or by which the Borrower or any Subsidiary is bound which default would reasonably be expected to have a Material Adverse Effect.

Section 3.13 Use of Proceeds and Letters of Credit. The proceeds of the Loans are or will be used solely (a) to renew and restate the Existing Loan Indebtedness, (b) to reimburse each Issuing Bank for LC Disbursements in accordance with Section 2.4(e), or (c) to finance the acquisition, exploration, development and operation of Mineral Interests and related Property and for any other business activities described in Section 3.10, and for the Borrower’s and its Subsidiaries’ working capital and general corporate purposes in the ordinary course of business. Letters of Credit will be issued only to support business operations described in Section 3.10 and/or general corporate purposes in the ordinary course of business of the Borrower or any of its Subsidiaries.

Section 3.14 Location of Business and Offices.

ARTICLE IX
AGENTS

Each of the Lenders, the Issuing Banks and the other Agents hereby irrevocably appoints JPMorgan Chase Bank, N.A., as the Global Administrative Agent, JPMorgan Chase Bank, N.A., Toronto Branch, as the Canadian Administrative Agent, BNP Paribas and Bank of America, N.A., as Co-Global Syndication Agents, and Fortis Capital Corp., The Bank of Nova Scotia and Deutsche Bank Trust Company Americas, as Co-Global Documentation Agents, and authorizes each such Agent to take such actions on its behalf and to exercise such powers as are delegated to such Agent by the terms of the Loan Documents, together with such actions and powers as are reasonably incidental thereto.

Any bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

The Agents shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Agents shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) each Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that such Agent is required to exercise following its receipt of written instructions from the Required Lenders (or such other number or percentage of the Combined Lenders as shall be necessary under the circumstances as provided in Section 10.2), and (c) except as expressly set forth in the Loan Documents, the Agents shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Parent, the Borrower or any of its Subsidiaries that is communicated to or obtained by the bank serving as such Agent or any of its Related Parties in any capacity. Each Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Combined Lenders as shall be necessary under the circumstances as provided in Section 10.2) or in the absence of its own gross negligence or willful misconduct; PROVIDED, HOWEVER, THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT EACH OF THE AGENTS BE INDEMNIFIED IN THE CASE OF ITS OWN NEGLIGENCE (OTHER THAN GROSS NEGLIGENCE), REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. Each Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to such Agent by the Borrower or a Lender, and such Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV

or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to such Agent.

The Global Administrative Agent, the Canadian Administrative Agent and the other Agents shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Global Administrative Agent, the Canadian Administrative Agent and the other Agents also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Global Administrative Agent, the Canadian Administrative Agent and the other Agents may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Any Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by such Agent. Any Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of such Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as an Agent.

Subject to the appointment and acceptance of a successor Global Administrative Agent or Canadian Administrative Agent as provided in this paragraph, the Global Administrative Agent or Canadian Administrative Agent may resign at any time by notifying the Combined Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right, with the consent of the Parent and the Borrower (unless an Event of Default has occurred and is continuing), to appoint a successor. If no successor shall have been so appointed by the Required Lenders, with such consent of the Parent and the Borrower (unless an Event of Default has occurred and is continuing), and shall have accepted such appointment within 30 days after the retiring Global Administrative Agent or the retiring Canadian Administrative Agent gives notice of its resignation, then the retiring Global Administrative Agent or retiring Canadian Administrative Agent may, with the consent of the Parent and the Borrower (unless an Event of Default has occurred and is continuing) on behalf of the Combined Lenders and the Issuing Banks, appoint a successor Global Administrative Agent or successor Canadian Administrative Agent, respectively, which shall be a commercial bank organized under the laws of the United States of America or the laws of Canada, respectively, having combined capital and surplus of at least U.S.$100,000,000, or an Affiliate of any such bank. Upon the acceptance of its appointment as Global Administrative Agent or Canadian Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Global Administrative Agent or retiring Canadian Administrative Agent, as the case may be, and the retiring Global Administrative Agent or retiring Canadian Administrative Agent shall be discharged from its duties and obligations hereunder (other than its obligations under Section 10.12). The fees payable by the Borrower to a successor Global Administrative Agent or successor Canadian Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and

such successor. After the Global Administrative Agent’s or Canadian Administrative Agent’s resignation hereunder, the provisions of this Article and Section 10.3 shall continue in effect for the benefit of such retiring Global Administrative Agent or retiring Canadian Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Global Administrative Agent or the Canadian Administrative Agent, respectively.

Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the Intercreditor Agreement. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

Each of the Lenders, for itself and on behalf of any of its Affiliates, the Issuing Banks, and the other Agents hereby irrevocably appoints the Global Administrative Agent and the Canadian Administrative Agent to act as its agent under the Intercreditor Agreement and authorizes the Global Administrative Agent and the Canadian Administrative Agent to execute the Intercreditor Agreement on its behalf and to take such actions on its behalf and to exercise such powers as are delegated to the Global Administrative Agent or the Canadian Administrative Agent by the terms hereof and thereof, together with such actions and powers as are reasonably incidental thereto.

Without limiting the provisions of Section 7.5(b) of the U.S. Credit Agreement, each of the Lenders, for itself and on behalf of any of its Affiliates, and the Issuing Banks hereby authorize the Global Administrative Agent to release any Collateral or Guaranties that are permitted to be sold or released pursuant to the Loan Documents, and the Global Administrative Agent agrees to promptly release any such items upon written request from the Borrower. Each Lender and each Issuing Bank hereby authorizes the Global Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, releases of Guaranties, termination statements, or other documents reasonably requested by the Borrower in connection with (i) any sale or disposition of Collateral, or (ii) any Subsidiary ceasing to be a Material Subsidiary hereunder, or otherwise pursuant to any other transaction permitted by this Agreement or the other Combined Loan Documents.

Section 10.2 Waivers; Amendments.

(a) No failure or delay by the Global Administrative Agent, the Canadian Administrative Agent, any Issuing Bank or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Global Administrative Agent, the Canadian Administrative Agent, the Issuing Banks and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Global Administrative Agent, the Canadian Administrative Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any of the Combined Loan Documents nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Global Administrative Agent and the Canadian Administrative Agent with the consent of the Majority Lenders, or, in the case of any other Combined Loan Document, pursuant to an agreement or agreements in writing entered into by the relevant Loan Parties thereto and the Majority Lenders or by the relevant Loan Parties thereto and the Global Administrative Agent and the Canadian Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Global Commitment or Commitment of any Lender without the written consent of such Lender (other than, in the case of a Commitment of a Lender, pursuant to a reallocation in accordance with Section 2.1(c)), (ii) reduce, or otherwise release the Borrower from its obligation to pay, the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any

Notwithstanding anything to the contrary contained in the Combined Loan Documents, the Parent and/or any of its Subsidiaries shall be permitted at any time to consummate, or cause to be consummated, the MLP Transactions (as defined in the U.S. Credit Agreement) or any part thereof without any further consent or approval of any of the Agents or Combined Lenders, provided such transactions are consummated in accordance and material compliance with the description set forth in Exhibit N to the U.S. Credit Agreement.

(e) All amounts due under this Section shall be payable not later than thirty (30) days after written demand is received by Borrower therefor.

Section 10.4 Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Bank that issues any Letter of Credit), except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Global Administrative Agent, each Issuing Bank and each Combined Lender (and any attempted assignment or transfer by the Borrower without such

consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of an Issuing Bank that issues any Letter of Credit) and, to the extent expressly contemplated hereby, the Related Parties of each of the Global Administrative Agent, the Issuing Banks and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Global Commitment, Commitment and the Loans at the time owing to it) to any Person who is not a Foreign Lender; provided that (i) except in the case of an assignment to a Lender, a Lender Affiliate or an Approved Fund, each of the Borrower (unless an Event of Default has occurred and is continuing) and the Global Administrative Agent and the Canadian Administrative Agent (and, in the case of an assignment of all or a portion of a Global Commitment or Commitment or any Lender’s obligations in respect of its LC Exposure, the Issuing Banks) must give their prior written consent to such assignment (which consents shall not be unreasonably withheld, conditioned or delayed), (ii) except in the case of an assignment to a Lender, a Lender Affiliate or an Approved Fund, or an assignment of the entire remaining amount of the assigning Lender’s Global Commitment, Commitment or Loans, the amount of the Global Commitment, Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Global Administrative Agent) shall be not less than U.S.$10,000,000 unless each of the Borrower (unless an Event of Default has occurred and is continuing), the Global Administrative Agent and the Canadian Administrative Agent otherwise consent, (iii) in the case of an assignment to a Lender, a Lender Affiliate, or an Approved Fund of an amount less than the entire remaining amount of the assigning Lender’s Global Commitment, Commitment or Loans, the amount of the Global Commitment, Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Global Administrative Agent) shall be not less than U.S.$5,000,000, (iv) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement, except that this clause (iv) shall not be construed to prohibit the assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of its Commitments or Loans in conformity with the Intercreditor Agreement, (v) the parties to each assignment shall execute and deliver to the Global Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of U.S.$3,500 to the Global Administrative Agent, (vi) the assignee, if it shall not be a Lender, shall deliver to the Global Administrative Agent an Administrative Questionnaire, (vii) after giving effect to any assignment under clause (ii), the assigning Lender shall have a Global Commitment of at least U.S.$10,000,000 and after giving effect to any assignment under clause (iii), the assigning Lender shall have a Global Commitment of at least U.S.$5,000,000, unless, in each case, each of the Borrower and the Global Administrative Agent otherwise consents, and (viii) any assignee Lender shall have the same Designation (which Designation may be changed in accordance with Section 2.1(c)) as the assigning Lender to the extent of the Global Commitment, Commitments and Loans so assigned by such assigning Lender; and provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default under Section 8.1 has occurred and is continuing. Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the

effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party hereto and to the other Loan Documents and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement and the other Loan Documents (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.15, Section 2.16, Section 2.17, Section 2.18, Section 2.20 and Section 10.3 and be subject to the terms of Section 10.12). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section.

(c) The Global Administrative Agent and the Canadian Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices in Chicago and Toronto, respectively, a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Global Commitment and Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Global Administrative Agent, the Canadian Administrative Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement and the other Loan Documents, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, any Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Global Administrative Agent will reflect the revisions on Schedule 2.1 and forward a copy of such revised Schedule 2.1 to the Borrower, each Issuing Bank and each Lender.

(d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section and any written consent to such assignment required by paragraph (b) of this Section, the Global Administrative Agent and the Canadian Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register and will provide prompt written notice to the Borrower of the effectiveness of such assignment. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(e) Any Lender may, without the consent of the Borrower, the Global Administrative Agent, the Canadian Administrative Agent or any Issuing Bank, sell participations to one or more banks or other entities which are entities in Canada for purposes of the Income Tax Act (Canada) (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Global Commitment, Commitment and the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other

parties hereto for the performance of such obligations, and (iii) the Borrower, the Global Administrative Agent, the Canadian Administrative Agent, the Issuing Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce the Loan Documents and to approve any amendment, modification or waiver of any provision of the Loan Documents; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the second proviso to Section 10.2(b) that affects such Participant. Subject to paragraph (f) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.15, Section 2.16 and Section 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.8 and Section 10.12 as though it were a Lender, provided such Participant agrees to be subject to Section 2.18(c) as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.15, Section 2.16 or Section 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as though it were a Lender.

(g) Any Lender may at any time pledge or assign a Lien in all or any portion of its rights under this Agreement to secure obligations of such Lender and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 10.5 Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that any Agent, any Issuing Bank, the Arrangers or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Global Commitments and Commitments have not expired or terminated. The provisions of Section 2.15, Section 2.16, Section 2.17, Section 2.18, Section 2.20, Section 10.3 and Section 10.12 and Article IX shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Global Commitments and Commitments or the termination of this Agreement or any provision hereof.

Section 10.6 Counterparts; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Except as provided in Section 4.1, this Agreement shall become effective when it shall have been executed by the Global Administrative Agent and the Canadian Administrative Agent and when the Global Administrative Agent and the Canadian Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy (or other electronic transmission acceptable to the Global Administrative Agent) shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 10.7 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 10.8 Right of Setoff. If an Event of Default shall have occurred and be continuing, each of the Agents, the Issuing Banks, the Lenders and their Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held, and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of, the Borrower or any of its Subsidiaries against any and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured; provided, however, that any such set-off and application shall be subject to the provisions of Section 2.18 and the Intercreditor Agreement. As security for such obligations, the Borrower hereby grants to the Agents, each Issuing Bank and each Lender a continuing security interest in any and all balances, credits, deposits, accounts or moneys of the Borrower and its Subsidiaries then or thereafter maintained with any of the Agents, such Issuing Bank and such Lenders. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Section 10.13 Interest Rate Limitation. It is the intention of the parties hereto to conform strictly to applicable interest, usury and criminal laws and, anything herein to the contrary notwithstanding, the obligations of the Borrower and the Guarantors to a Lender, any Issuing Bank or any Agent under this Agreement or any Combined Loan Document shall be subject to the limitation that payments of interest shall not be required to the extent that receipt thereof would be contrary to provisions of law applicable to such Lender, such Issuing Bank or Agent limiting rates of interest which may be charged or collected by such Lender, such Issuing Bank or Agent. Accordingly, if the transactions contemplated hereby or thereby would be illegal, unenforceable, usurious or criminal under laws applicable to a Lender, any Issuing Bank or any Agent (including the laws of any jurisdiction whose laws may be mandatorily applicable to such Lender or Agent notwithstanding anything to the contrary in this Agreement or any other Combined Loan Document then, in that event, notwithstanding anything to the contrary in this Agreement or any other Combined Loan Document, it is agreed as follows:

(i) the provisions of this Section shall govern and control;

(ii) the aggregate of all consideration which constitutes interest under applicable law that is contracted for, taken, reserved, charged or received under this Agreement or any Combined Loan Document or otherwise in connection with this Agreement or any Combined Loan Document by such Lender, such Issuing Bank or such Agent shall under no circumstances exceed the maximum amount of interest allowed by applicable law (such maximum lawful interest rate, if any, with respect to each Lender, each Issuing Bank and the Agents herein called the “Highest Lawful Rate”), and any excess shall be cancelled automatically and if theretofore paid shall be credited to the Borrower by such Lender, such Issuing Bank or such Agent (or, if such consideration shall have been paid in full, such excess refunded to the Borrower);

(iii) all sums paid, or agreed to be paid, to such Lender, such Issuing Bank or such Agent for the use, forbearance and detention of the indebtedness of the Borrower to such Lender, such Issuing Bank or such Agent hereunder or under any Combined Loan Document shall, to the extent permitted by laws applicable to such Lender, such Issuing Bank or such Agent, as the case may be, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in full so that the actual rate of interest is uniform throughout the full term thereof;

(iv) if at any time the interest provided pursuant to this Section or any other clause of this Agreement or any other Combined Loan Document, together with any other fees or compensation payable pursuant to this Agreement or any other Combined Loan Document and deemed interest under laws applicable to such Lender, such Issuing Bank or such Agent, exceeds that amount which would have accrued at the Highest Lawful Rate, then the amount of interest and any such fees or compensation to accrue to such Lender, such Issuing Bank or such Agent pursuant to this Agreement or such other Combined Loan Document shall be limited, notwithstanding anything to the contrary in this Agreement or any other Combined Loan Document, to that amount which would have accrued at the Highest Lawful Rate, but any subsequent reductions, as applicable, shall not reduce the interest to accrue to such Lender, such Issuing Bank or such Agent pursuant to this Agreement or such other Combined Loan Document below the Highest

103

Lawful Rate until the total amount of interest accrued pursuant to this Agreement or such other Combined Loan Document, as the case may be, and such fees or compensation deemed to be interest equals the amount of interest which would have accrued to such Lender or Agent if a varying rate per annum equal to the interest provided pursuant to any other relevant Section hereof (other than this Section) or thereof, as applicable, had at all times been in effect, plus the amount of fees which would have been received but for the effect of this Section; and

(v) with the intent that the rate of interest herein shall at all times be lawful, and if the receipt of any funds owing hereunder or under any other agreement related hereto (including any of the other Combined Loan Documents) by such Lender, such Issuing Bank or such Agent would cause such Lender to charge the Borrower a criminal rate of interest, the Lenders, the Issuing Banks and the Agents agree that they will not require the payment or receipt thereof or a portion thereof which would cause a criminal rate of interest to be charged by such Lender, such Issuing Bank or such Agent, as applicable, and if received such affected Lender, such Issuing Bank or Agent will return such funds to the Borrower so that the rate of interest paid by the Borrower shall not exceed a criminal rate of interest from the date this Agreement was entered into.

Notwithstanding any provision herein to the contrary, in no event will the aggregate “interest” (as defined in section 347 of the Criminal Code (Canada)) payable under this Agreement exceed the maximum effective annual rate of interest on the “credit advanced” (as defined in that section) permitted under that section and, if any payment, collection or demand pursuant to this Agreement in respect of “interest” (as defined in that section) is determined to be contrary to the provisions of that section, such payment, collection or demand will be deemed to have been made by mutual mistake of the Borrower, any Guarantor, the Lenders, the Issuing Bank and the Agent, as the case may be, and the amount of such excess payment or collection will be refunded to the Borrower or such Guarantor, as the case may be. For purposes of this Agreement, the effective annual rate of interest will be determined in accordance with generally accepted actuarial practices and principles over the term of the Loans on the basis of annual compounding of the lawfully permitted rate of interest and, in the event of dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by the Global Administrative Agent will be prima facie evidence, for the purposes of such determination.

Section 10.14 [Reserved].
