(A) if any Lender shall, at least one Business Day before the date of any requested Revolving Borrowing comprised of Eurodollar Rate Advances, notify the Administrative Agent (with a copy to the applicable Borrower) that the introduction of or any change in or in the interpretation of any law or regulation by any court, authority or agency, or any other

governmental, judicial or regulatory body, makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, the right of such Borrower to select Eurodollar Rate Advances for such Revolving Borrowing or any subsequent Revolving Borrowing, with respect to such Lender (only), shall be suspended until such Lender shall notify the Administrative Agent (with a copy to the applicable Borrower) that the circumstances causing such suspension no longer exist or such Lender shall cease to be a party hereto, and each Revolving Advance comprising such Revolving Borrowing shall, with respect to such Lender (only), be a Base Rate Advance of an equivalent amount and for an approximately equivalent term, provided that if all the Lenders so notify the Administrative Agent, the Administrative Agent shall so notify the applicable Borrower and the Notice of Revolving Borrowing in respect of such requested Revolving Borrowing shall be automatically revoked. Each Lender giving a notice under this subclause (A) shall, promptly after giving such notice, provide the Company (with a copy to the Administrative Agent) with an explanation, in reasonable detail, as to the circumstances causing such suspension;

(C) if US Lenders having more than 50% of the US Commitments shall, at least one Business Day before the date of any requested Revolving Borrowing comprised of Eurodollar Rate Advances, notify the Administrative Agent (with a copy to the applicable Borrower) that the Eurodollar Rate for Eurodollar Rate Advances comprising such Revolving Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurodollar Rate Advances for such Revolving Borrowing, the Notice of Revolving Borrowing given in respect of such requested Revolving Borrowing shall be automatically revoked and the right of the Borrowers to select Eurodollar Rate Advances for such Revolving Borrowing or any subsequent Revolving Borrowing shall be suspended until such Lenders shall notify the Administrative Agent (with a copy to the applicable Borrower) and the other Lenders that the circumstances causing such suspension no longer exist. The Lenders giving a notice under this subclause (C) shall, promptly after giving such notice, provide the Company (with a copy to the Administrative Agent) with an explanation, in reasonable detail, as to the circumstances causing such suspension.

(iii) Each Notice of Revolving Borrowing (subject to (ii)(A) and (ii)(C) above) shall be irrevocable and binding on the Borrower giving such notice. In the case of any Revolving Borrowing which the related Notice of Revolving Borrowing specifies is to be comprised of Eurodollar Rate Advances, the applicable Borrower shall indemnify each Lender against any loss,

cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Revolving Borrowing for such Revolving Borrowing the applicable conditions set forth in Article III , including, without limitation, any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Revolving Advance to be made by such Lender as part of such Revolving Borrowing when such Revolving Advance, as a result of such failure, is not made on such date. Each Lender claiming indemnity for any such loss, cost or expense under this clause (iii) shall provide, at the time of making such claim, the applicable Borrower (with a copy to the Administrative Agent) with reasonable details, including the basis for the calculation thereof, of such loss, cost or expense, provided that, in the absence of manifest error, the amount of such claims so notified shall be conclusive and binding upon such Borrower.

(iv) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Revolving Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Revolving Borrowing in accordance with subsection (i) of this Section 2.02(a) and the Administrative Agent may, in reliance upon such assumption, make available to the applicable Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made such ratable portion available to the Administrative Agent, such Lender and such Borrower severally agree to repay to the Administrative Agent forthwith on demand such corresponding amount together with interest thereon, for each date from the date such amount is made available to such Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of a Borrower, the Base Rate and (ii) in the case of such Lender, (1) in the case of Advances denominated in US Dollars, the Federal Funds Rate and (2) in the case of Advances denominated in Canadian Dollars, the Canadian Interbank Rate. If the applicable Borrower shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the applicable Borrower the amount of such interest paid by the applicable Borrower for such period. If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s Revolving Advance as part of such Revolving Borrowing for purposes of this Agreement.

Issuing Bank will, upon fulfillment of the applicable conditions set forth in Article III , make such Letter of Credit available to the Company at its office referred to in Section 10.02 or as otherwise agreed with the Company in connection with such issuance.

Each US 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 an Event of Default or any event which, with the giving of notice or lapse of time, or both, would constitute an Event of Default, or reduction or termination of the US Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each US Lender further acknowledges and agrees that its participation in each Letter of Credit will be automatically adjusted to reflect such Lender’s Pro Rata Share of such Letter of Credit at each time such Lender’s US Commitment is amended pursuant to Section 2.04 , pursuant to an assignment in accordance with Section 9.02 or otherwise pursuant to this Agreement.

(iii) Drawing and Reimbursement . The payment by any Issuing Bank of a draft drawn under any Letter of Credit shall constitute for all purposes of this Agreement the making by such Issuing Bank of a Revolving Advance, which shall be a Base Rate Advance, in the amount of such draft. Upon written demand by such Issuing Bank, with a copy of such demand to the Administrative Agent, each US Lender shall pay to the Administrative Agent such Lender’s Pro Rata Share of such outstanding Revolving Advance, by making available for the account of its Applicable Lending Office to the Administrative Agent for the account of such Issuing Bank, by deposit to the Administrative Agent, in the Administrative Agent’s Account, in same day funds, an amount equal to the portion of the outstanding principal amount of such Revolving Advance to be funded by such Lender.

If and to the extent that any US Lender shall not have so made the amount of such Revolving Advance available to the Administrative Agent, such Lender agrees to pay to the Administrative Agent forthwith on demand such amount together with interest thereon, for each day from the date of demand by the applicable Issuing Bank until the date such amount is paid to the Administrative Agent, at the Federal Funds Rate for its account or the account of such Issuing Bank, as applicable. If such Lender shall pay to the Administrative Agent such amount for the account of such Issuing Bank on any Business Day, such amount so paid in respect of principal shall constitute a Revolving

Advance made by such Lender on such Business Day for purposes of this Agreement, and the outstanding principal amount of the Revolving Advance made by the applicable Issuing Bank shall be reduced by such amount on such Business Day.

(iv) Letter of Credit Reports . Each Issuing Bank shall furnish (A) to the Administrative Agent on the first Business Day of each week a written report summarizing issuance and expiration dates of Letters of Credit issued by it during the previous week and drawings during such week under all Letters of Credit issued by it and (B) to the Administrative Agent on the first Business Day of each calendar quarter a written report setting forth the average daily aggregate Available Amount during the preceding calendar quarter of all Letters of Credit issued by it.

(vi) Failure to Make Revolving Advances . The failure of any US Lender to make the Revolving Advance to be made by it on the date specified in Section 2.02(b)(iii) shall not relieve any other US Lender of its obligation hereunder to make its Revolving Advance on such date, but no US Lender shall be responsible for the failure of any other US Lender to make the Revolving Advance to be made by such other US Lender on such date.

Within 10 days after its receipt of any such notice, each Lender shall notify the Administrative Agent of its willingness or unwillingness so to extend its Commitment(s). Any Lender which shall fail so to notify the Administrative Agent within such period shall be deemed to have declined to extend its Commitment. In the event that Lenders having US Commitments equal to US$100,000,000 or more shall be willing to extend their respective US Commitments, the Administrative Agent shall so notify the Company and each Lender and the Termination Date for each consenting Lender (including consenting Canadian Lenders) shall without further action be extended to the Extended Termination Date.

The Administrative Agent shall notify the applicable Lenders and such other Eligible Assignees as the Company may identify thereof promptly of a request by the Company for a Commitment Increase, which notice shall include (x) the proposed amount of such requested Commitment Increase, (y) the proposed Increase Date and (z) the date by which Lenders wishing to participate in the Commitment Increase must commit to any increase in the amount of their respective Commitments, which date shall not be less than ten Business Days from the date of delivery of such notice to the Lenders (the “ Commitment Date ”). Each such Lender that is willing to increase its existing US Commitment or existing Canadian Commitment hereunder (an “ Increasing Lender ”) and each such Eligible Assignee that agrees to participate in such Commitment Increase as an Assuming Lender, subject to Section 2.04(c) , in its sole discretion, shall give written notice to the Administrative Agent on or prior to the Commitment Date of the amount by which it is willing to increase its Commitment or to participate in such Commitment Increase; provided further that the minimum Commitment of each such Assuming Lender that becomes a party to this Agreement pursuant to this Section 2.04(d) , shall be at least equal to US$5,000,000.

(New York City time) on the Increase Date to the satisfaction of the Administrative Agent, the Administrative Agent shall notify the Lenders (including any Assuming Lenders) and the Company of the occurrence of such Commitment Increase by telecopier promptly and in any event no later than 1:00 P.M. (New York City time) on the Increase Date and shall record in the Register the relevant information with respect to each Increasing Lender and Assuming Lender. If (x) Advances are outstanding under the applicable increased Commitments and (y) the applicable Commitment Increase is not ratable among the Canadian Lenders or the US Lenders, as applicable, each Increasing Lender and each Assuming Lender shall, before 2:00 P.M. (New York City time) on the Increase Date, make available for the account of its Applicable Lending Office to the Administrative Agent, in the Administrative Agent’s Account, in same day funds, in the case of such Assuming Lender, an amount equal to such Assuming Lender’s ratable portion of the applicable Revolving Borrowings then outstanding (calculated based on its applicable Commitment as a percentage of the aggregate applicable Commitments after giving effect to the relevant Commitment Increase) and, in the case of such Increasing Lender, an amount equal to the excess of (i) such Increasing Lender’s ratable portion of the Revolving Borrowings then outstanding (calculated based on its applicable Commitment as a percentage of the aggregate applicable Commitments outstanding after giving effect to the relevant Commitment Increase) over (ii) such Increasing Lender’s ratable portion of the Revolving Borrowings then outstanding (calculated based on its applicable Commitment (without giving effect to the relevant Commitment Increase) as a percentage of the aggregate applicable Commitments (without giving effect to the relevant Commitment Increase). After the Administrative Agent’s receipt of such funds from each such Increasing Lender and each such Assuming Lender, the Administrative Agent will promptly thereafter cause to be distributed like funds to the other Lenders for the account of their respective Applicable Lending Offices in an amount to each other Lender such that the aggregate amount of the outstanding Revolving Advances owing to each Lender after giving effect to such distribution equals such Lender’s ratable portion of the Revolving Borrowings then outstanding (calculated based on its applicable Commitment as a percentage of the aggregate applicable Commitments outstanding after giving effect to the relevant Commitment Increase).

(iii) In the event that (A) the Administrative Agent shall not have received notice from the Company as to such agreement on or prior to the Commitment Date, (B) the Company shall, by notice to the Administrative Agent prior to the Increase Date, withdraw its proposal for a

Commitment Increase or (C) any of the actions provided for above in clauses (i)(1) through (i)(3) shall not have occurred by 10:00 A.M. (New York City time) on the Increase Date, such proposal by the Company shall be deemed not to have been made.

(e) Notwithstanding the foregoing provisions of this Section, a Lender shall not be entitled to compensation pursuant to this Section in respect of any Bid Advances if the Change in Law which would otherwise entitle it to such compensation shall have been publicly announced prior to submission of the Notice of Bid Borrowing pursuant to which such Advance was made.

Each determination by the Administrative Agent (or, in the case of Section 2.07 , by a Lender) of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(c) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day or, in the case of payments in respect of Canadian Advances, other than a Canadian Business Day, such payment shall be made on the next succeeding Business Day or Canadian Business Day, as the case may be, and such extension of time shall in such case be included in the computation of payment of interest and fees, as the case may be; provided , however , if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment, shall be made on the next preceding Business Day or Canadian Business Day, as the case may be.

(d) Unless the Administrative Agent shall have received notice from the applicable Borrower prior to the date on which any payment is due to the Lenders hereunder that such Borrower will not make such payment in full, the Administrative Agent may assume that such Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender or the applicable Issuing Bank, as the case may be, on such due date an amount equal to the amount then due such Lender or such Issuing Bank, as the case may be. If and to the extent the applicable Borrower shall not have so made such payment in full to the Administrative Agent, each Lender or the applicable Issuing Bank, as the case may be, shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender or such Issuing Bank, as the case may be, together with interest thereon, for each day from the date such amount is distributed to such Lender or such Issuing Bank, as the case may be, until the date such Lender or such Issuing Bank, as the case may be, repays such amount to the Administrative Agent, in the case of payments made in US Dollars at the Federal Funds Rate and in the case of payments made in Canadian Dollars, at the Canadian Interbank Rate.

(e) For the purposes of the Interest Act (Canada) and disclosure under such act, whenever any interest or fees to be paid under this Agreement are to be calculated on the basis of a year of 365 days or 360 days or any other period of time that is less than a calendar year, the yearly rate of interest to which the rate determined pursuant to such calculation is equivalent is the rate so determined multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by either 365, 360 or such other period of time, as the case may be.

(f) Notwithstanding any provision of this Agreement, in no event shall the aggregate “interest” (as defined in section 347 of the Criminal Code (Canada)) payable under this Agreement exceed the effective annual rate of interest on the “credit advanced” (as defined in that section) under this Agreement lawfully permitted by 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 shall be deemed to have been made by mutual mistake of the Borrowers, the Administrative Agent and the Lenders and the amount of such payment or collection shall be refunded to the applicable Borrower. For the purposes of this Agreement, the effective annual rate of interest shall be determined in accordance with generally accepted actuarial practices and principles over the relevant term and, in the event of dispute, a certificate of a Fellow of the Canadian Institute of Actuaries appointed by the Administrative Agent will be prima facie evidence of such rate.

Section 2.12 Evidence of Indebtedness . (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of each Borrower to such Lender resulting from each Revolving Advance owing to such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder in respect of Revolving Advances. Each Borrower agrees that upon notice by any Lender to such Borrower (with a copy of such notice to the Administrative Agent) to the effect that a Revolving Note is required or appropriate in order for such Lender to evidence (whether for purposes of pledge, enforcement or otherwise) the Revolving Advances owing to, or to be made by, such Lender, such Borrower shall promptly execute and deliver to such Lender a Revolving Note payable to the order of such Lender, in the case of the Company, in a principal amount up to the US Commitment of such Lender and in the case of the Canadian Borrower, in a principal amount up to the Canadian Commitment of such Lender.

(b) The Register maintained by the Administrative Agent pursuant to Section 9.02 shall include a control account, and a subsidiary account for each Lender, in which accounts (taken together) shall be recorded (i) the date and amount of each Borrowing made hereunder, the Type of Advances comprising such Borrowing and, if appropriate, the Interest Period applicable thereto, (ii) the terms of each Assignment and Assumption delivered to and accepted by it, (iii) the amount of any principal or interest due and payable or to become due and payable from each Borrower to each Lender hereunder and (iv) the amount of any sum received by the Administrative Agent from each Borrower hereunder and each Lender’s share thereof.

(c) Entries made in good faith by the Administrative Agent in the Register pursuant to subsection (b) above, and by each Lender in its account or accounts pursuant to subsection (a) above, shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrowers to, in the case of the Register, each Lender and, in the case of such account or accounts, such Lender, under this Agreement, absent manifest error; provided , however , that the failure of the Administrative Agent or such Lender to make an entry, or any finding that an entry is incorrect, in the Register or such account or accounts shall not limit or otherwise affect the obligations of the Borrowers under this Agreement.

Section 2.13 Sharing of Payments, Etc. (a) If any US Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the US Advances owing by the Company to it (other than pursuant to Section 2.04(b) , 2.04(c) , 2.07 , 2.10 or 2.14 ) in excess of its ratable share of payments on account of the Revolving Advances made to the Company obtained by all the Lenders, such US Lender shall notify the Administrative Agent of such fact and forthwith purchase (for cash at face value) from the other Lenders such participations in the US Advances made to the Company owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them, provided , however , that (i) if all or any portion of such excess payment is thereafter recovered from such purchasing US Lender, such purchase from each US Lender shall be rescinded and such US Lender shall repay to the purchasing US Lender the purchase price to the extent of such recovery together with an amount equal to such US Lender’s ratable share (according to the proportion of (A) the amount of such US Lender’s required repayment to (B) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing US Lender in respect of the total amount so recovered and (ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by a Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), (y) the application of Cash Collateral provided for in Section 2.19 or (z) any payment obtained by a US Lender as consideration for the assignment of or sale of a participation in any of its US Advances or participations and Letters of Credit to any assignee or participant, other than to the Borrowers or any of their respective Subsidiaries or Affiliates (as to which the provisions of this paragraph shall apply). The Company agrees that any US Lender so purchasing a participation from

another US Lender pursuant to this Section 2.13 may, to the fullest extent permitted by law, exercise all its rights of payment with respect to such participation as fully as if such US Lender were the direct creditor of the Company in the amount of such participation.

(b) If any Canadian Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Canadian Advances owing by any Borrower to it (other than pursuant to Section 2.04(b) , 2.04(c) , 2.07 , 2.10 or 2.14 ) in excess of its ratable share of payments on account of the Revolving Advances made to such Borrower obtained by all the Lenders, such Canadian Lender shall notify the Administrative Agent of such fact and forthwith purchase (for cash at face value) from the other Canadian Lenders such participations in the Canadian Advances made to such Borrower owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them, provided , however , that (i) if all or any portion of such excess payment is thereafter recovered from such purchasing Canadian Lender, such purchase from each Canadian Lender shall be rescinded and such Canadian Lender shall repay to the purchasing Canadian Lender the purchase price to the extent of such recovery together with an amount equal to such Canadian Lender’s ratable share (according to the proportion of (A) the amount of such Canadian Lender’s required repayment to (B) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Canadian Lender in respect of the total amount so recovered and (ii) the provisions of this paragraph shall not be construed to apply to (1) any payment made by a Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (2) any payment obtained by a Canadian Lender as consideration for the assignment of or sale of a participation in any of its Canadian Advances or participations and Letters of Credit to any assignee or participant, other than to the Borrowers or any of their respective Subsidiaries or Affiliates (as to which the provisions of this paragraph shall apply). Each Borrower agrees that any Canadian Lender so purchasing a participation from another Canadian Lender pursuant to this Section 2.13 may, to the fullest extent permitted by law, exercise all its rights of payment with respect to such participation as fully as if such Canadian Lender were the direct creditor of such Borrower in the amount of such participation.

Each 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 such Borrower rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

Section 2.14 Taxes .

(a) Issuing Bank . For purposes of this Section 2.14 , the term “Lender” includes any Issuing Bank.

(b) Payments Free of Taxes . Any and all payments by or on account of any obligation of the Borrowers under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrowers shall be increased as necessary so that, after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section), the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c) Payment of Other Taxes by the Company . The Company shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for the payment of, any Other Taxes.

(d) Indemnification by the Company . The Company shall indemnify each Recipient, within 30 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Company by a Recipient (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Recipient, shall be conclusive absent manifest error.

(e) Indemnification by the Lenders . Each Lender shall severally indemnify, within ten (10) days after demand therefor, (i) the Administrative Agent, for any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrowers have not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrowers to do so), (ii) the Administrative Agent, for any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.03 relating to the maintenance of a Participant Register and (iii) the Administrative Agent and the Borrowers, for any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent (or, in the case of this clause (iii), the applicable Borrower) in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent (or, in the case of clause (iii) above, by the Administrative Agent or the applicable Borrower) shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).

(f) Evidence of Payments . Within 30 days after any payment of Taxes by the Borrowers to a Governmental Authority pursuant to this Section 2.14 , the applicable Borrower shall deliver to the 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 Administrative Agent.

(g) Status of Lenders .

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the applicable Borrower and the Administrative Agent, at the time or times reasonably requested by the applicable Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the applicable Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the applicable Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the applicable Borrower or the Administrative Agent as will enable the applicable Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such

documentation (other than such documentation set forth in Section 2.14(g)(ii)(A) , (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing, in the event that a Borrower is a U.S. Person:

(A) Any Lender that is a U.S. Person shall deliver to such Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from United States federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to such Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of such Borrower or the Administrative Agent), whichever of the following is applicable:

(1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, United States federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, United States federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2) executed originals of IRS Form W-8ECI;

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrowers within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “ U.S. Tax Compliance Certificate ”) and (y) executed originals of IRS Form W-8BEN; or

(4) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-2 or Exhibit F-3 , IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit F-4 on behalf of each such direct and indirect partner;

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Company and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Company or the

Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Company or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to United States federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the applicable Borrower and the Administrative Agent at the time or times prescribed by law and at such time or Company reasonably requested by the Company or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Company or the Administrative Agent as may be necessary for such Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the applicable Borrower and the Administrative Agent in writing of its legal inability to do so.

(h) Treatment of Certain Refunds . If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 2.14 (including by the payment of additional amounts pursuant to this Section 2.14 ), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (h) ( plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the indemnification payments or additional amounts giving rise to such refund had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i) Survival . Each party’s obligations under this Section 2.14 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

Section 2.15 Interest Elections . (a) Each Revolving Borrowing initially shall be of the Type specified in the applicable Notice of Revolving Borrowing and, in the case of a Eurodollar Rate Revolving Borrowing, shall have an initial Interest Period as specified in such Notice of Revolving Borrowing, provided , that each Revolving Advance made as a result of a drawing under a Letter of Credit

shall be a Base Rate Advance unless and until each US Lender shall have acquired participations equal to such Lender’s Pro Rata Share of the amount drawn under such Letter of Credit pursuant to Section 2.02(b)(ii) (after which time the Company shall be entitled, pursuant to the immediately succeeding sentence, to convert any such Base Rate Advance to a Eurodollar Rate Advance). Thereafter, subject to the provisions of Section 2.16 with respect to Bankers’ Acceptances and BA Equivalent Notes, the applicable Borrower may elect to convert such Revolving Borrowing to a different Type of Revolving Advance denominated in the same currency or to continue such Revolving Borrowing and, in the case of a Eurodollar Rate Revolving Borrowing, may elect Interest Periods therefor, all as provided in this Section. The applicable Borrower may elect different options with respect to different portions of the affected Revolving Borrowing, in which case each such Revolving Borrowing shall be allocated ratably among the Lenders having made the Revolving Advances comprising such Revolving Borrowing, and the Revolving Advances comprising each such portion shall be considered a separate Revolving Borrowing. This Section shall not apply to Bid Borrowings, which may not be converted or continued.

(b) To make an election pursuant to this Section, the applicable Borrower shall notify the Administrative Agent of such election by telephone by the time that a Notice of Revolving Borrowing would be required under Section 2.02 if such Borrower were requesting a Revolving 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 Administrative Agent of a written Interest Election Request signed by the applicable Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02 :

(i) the Revolving 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 Revolving Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Revolving Borrowing);

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

(iii) the Type of Revolving Advances comprising such Revolving Borrowing; and

(iv) in the case of a Eurodollar Rate Advance, the Interest Period for each such Revolving Advance.

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

(d) If a Borrower fails to deliver a timely Interest Election Request with respect to a Revolving Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Revolving Borrowing is repaid as provided herein, at the end of such Interest Period such Revolving Borrowing shall be continued as or converted to a Base Rate Revolving Borrowing.

(e) If, after the occurrence and during the continuance of any Event of Default, the Majority Lenders so direct, (i) each Eurodollar Rate Advance will automatically, on the last day of the

then existing Interest Period therefor, be converted into Base Rate Advances and (ii) the obligation of the Lenders to make, or to convert Advances into, Eurodollar Rate Advances shall be suspended.

Section 2.16 Drawings of Bankers’ Acceptances and BA Equivalent Notes . (a) Request for Drawing . Each Drawing shall be made on notice, given not later than 11:00 A.M. (New York City time) on a Canadian Business Day at least two Canadian Business Days prior to the date of the proposed Drawing, by the Canadian Borrower to the Administrative Agent, which shall give each Canadian Lender prompt notice thereof by telecopier. Each notice of a Drawing shall be in writing (including by telecopier), in substantially the form of Exhibit B-3 hereto, specifying therein the requested (i) date of such Drawing (which shall be a Canadian Business Day), (ii) aggregate Face Amount of such Drawing and (iii) initial Maturity Date for each Bankers’ Acceptance and BA Equivalent Note comprising part of such Drawing; provided , however , that, if the Administrative Agent determines in good faith (which determination shall be conclusive and binding upon the Canadian Borrower) that the Drafts to be accepted and purchased as part of any Drawing cannot, due solely to the requested aggregate Face Amount thereof, be accepted and/or purchased ratably by the Canadian Lenders in accordance with Section 2.01(c) , then the aggregate Face Amount of such Drawing (or the Face Amount of Bankers’ Acceptances and BA Equivalent Notes to be created and purchased by any Canadian Lender) shall be reduced to such lesser amount as the Administrative Agent determines will permit such Drafts comprising part of such Drawing to be so accepted and purchased. The Administrative Agent agrees that it will, as promptly as practicable, notify the Canadian Borrower of the unavailability of Bankers’ Acceptances in accordance with Section 2.16(e) . Each Draft in connection with any requested Drawing (A) shall be in a minimum amount of CN$1,000,000 or an integral multiple of CN$100,000 in excess thereof, and (B) shall be dated the date of the proposed Drawing. Each Canadian Lender that is a BA Lender shall, before 1:00 P.M. (Toronto time) on the date of each Drawing, complete one or more Drafts in accordance with the related Notice of Borrowing, accept such Drafts and purchase the Bankers’ Acceptances created thereby for the Drawing Purchase Price and shall, before 1:00 P.M. (Toronto time) on such date, make available for the account of its Applicable Lending Office to the Administrative Agent, in the Administrative Agent’s Account, in same day funds, the Drawing Purchase Price payable by such Canadian Lender for such Drawing less the Stamping Fee payable to such Canadian Lender with respect thereto under Section 2.16(b) . Each Non-BA Lender shall, in lieu of accepting its proportionate amount of Bankers Acceptances forming part of a Drawing, make available the Canadian Borrower a loan (a “ BA Equivalent Note ”) in Canadian Dollars in an amount equal to the Drawing Purchase Price of the Bankers’ Acceptances that such Non-BA Lender would have been required to accept if it were a BA Lender. Each Non-BA Lender shall, before 1:00 P.M. (Toronto time) on the date of each Drawing, make available for the account of its Applicable Lending Office to the Administrative Agent, in the Administrative Agent’s Account, in same day funds, the amount of the BA Equivalent Note, less an amount equal to the Stamping Fee that would have been applicable to the BA Equivalent Note had it been a Bankers’ Acceptance. Upon the fulfillment of the applicable conditions set forth in Section 3.03 , the Administrative Agent will make the funds it has received from the Canadian Lenders available to the Canadian Borrower requesting such Drawing at the Administrative Agent’s address set forth on Schedule 10.02 .

(b) Stamping Fees . The Canadian Borrower shall, on the date of each Drawing and on the date of each renewal of any outstanding Bankers’ Acceptances or BA Equivalent Notes, pay to the Administrative Agent, in Canadian Dollars, for the ratable account of the Canadian Lenders accepting Drafts and purchasing Bankers’ Acceptances or making BA Equivalent Notes, the Stamping Fee with respect to such Bankers’ Acceptances or corresponding BA Equivalent Notes. The Canadian Borrower irrevocably authorizes each such Canadian Lender to deduct the Stamping Fee payable with respect to each Bankers’ Acceptance or BA Equivalent Notes of such Canadian Lender from the Drawing Purchase Price payable by such Canadian Lender in respect of such Bankers’ Acceptance or BA Equivalent Notes in accordance with this Section 2.16 and to apply such amount so withheld to the payment of such Stamping Fee for the account of the Canadian Borrower and, to the extent such Stamping Fee is so

withheld and legally permitted to be so applied, the Canadian Borrower’s obligations under the preceding sentence in respect of such Stamping Fee shall be satisfied.

(c) Limitations on Drawings . Anything in Section 2.16(a) to the contrary notwithstanding, the Canadian Borrower may not select a Drawing if the obligation of the Canadian Lenders to purchase and accept Bankers’ Acceptances shall then be suspended pursuant to Section 2.16(e) or 2.16(o) .

(d) Binding Effect of Notices of Borrowing . Each Notice of Borrowing for a Drawing shall be irrevocable and binding on the Canadian Borrower. In the case of any proposed Drawing, the Canadian Borrower shall indemnify each Canadian Lender (absent any gross negligence by the Canadian Lender) against any loss, cost or expense incurred by such Canadian Lender as a result of any failure to fulfill on or before the date specified in the Notice of Borrowing for such Drawing the applicable conditions set forth in Section 3.03 , including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Canadian Lender to fund the Drawing Purchase Price (or in the case of Non-BA Lenders, the BA Equivalent Note) to be paid by such Canadian Lender as part of such Drawing when, as a result of such failure, such Drawing is not made on such date (but, in any event, excluding any loss of profit and the Stamping Fee applicable to such Drawing or Advance).

(e) Circumstances Making Bankers’ Acceptances Unavailable . (i) If, with respect to any proposed Drawing, the Administrative Agent determines in good faith that circumstances affecting the money markets at the time any related Notice of Borrowing is delivered or is outstanding will result in there being no market for the Bankers’ Acceptances to be created in connection with such Drawing or an insufficient demand for such Bankers’ Acceptances to allow the Canadian Lenders creating such Bankers’ Acceptances to sell or trade the Bankers’ Acceptances to be created and purchased or discounted by them hereunder in connection with such Drawing, then, upon notice to the Canadian Borrower and the Canadian Lenders thereof, (A) the Notice of Borrowing with respect to such proposed Drawing shall be cancelled and the Drawing requested therein shall not be made and (B) the right of the Canadian Borrower to request a Drawing shall be suspended until the Administrative Agent shall notify the Canadian Borrower that the circumstances causing such suspension no longer exist. The Administrative Agent agrees that it will, as promptly as practicable, notify the Canadian Borrower of the unavailability of Bankers’ Acceptances.

(ii) Upon the occurrence and during the continuance of any Default, the obligation of the Canadian Lenders to create and purchase Bankers’ Acceptances shall be suspended.

(iii) If the Reuters Screen CDOR Page is not available for the timely determination of the BA Rate, and the BA Rate for any Bankers’ Acceptances or BA Equivalent Notes can not otherwise be determined in a timely manner in accordance with the definition of “BA Rate”, the Administrative Agent shall forthwith notify the Canadian Borrower and the Canadian Lenders that such interest rate cannot be determined for such Bankers’ Acceptances and BA Equivalent Notes, and the obligation of the Canadian Lenders to make, or to renew, Bankers’ Acceptances and BA Equivalent Notes shall be suspended until the Administrative Agent shall notify the Canadian Borrower and the Canadian Lenders that the circumstances causing such suspension no longer exist.

(iv) If Canadian Lenders having more than 50% of the Canadian Commitments shall, at least one (1) Canadian Business Day before the date of the applicable requested Drawing, notify the Administrative Agent (with a copy to the Canadian Borrower) that the BA Rate for Bankers' Acceptances or BA Equivalent Notes comprising such Drawing will not adequately

reflect the discount rate which would be applicable to a sale of Bankers' Acceptances accepted by such Canadian Lenders which are BA Lenders in the market for the applicable term or the cost to such Canadian Lenders which are Non-BA Lenders of making or funding their respective BA Equivalent Notes comprising such Drawing, the Notice of Borrowing given in respect of such requested Drawing shall be cancelled and the Drawing requested therein shall not be made and the right of the Canadian Borrower to request a Drawing shall be suspended until such Canadian Lenders shall notify the Administrative Agent (with a copy to the Canadian Borrower) and the other Canadian Lenders that the circumstances causing such suspension no longer exist. The Canadian Lenders giving a notice under this subclause (iv) shall, promptly after giving such notice, provide the Canadian Borrower (with a copy to the Administrative Agent) with an explanation, in reasonable detail, as to the circumstances causing such suspension.

(f) Assumptions of the Administrative Agent . Unless the Administrative Agent shall have received notice from a Canadian Lender prior to the date of any Drawing that such Canadian Lender will not make available to it such Canadian Lender’s ratable share of the proceeds of such Drawing, in accordance with Section 2.16(a) , the Administrative Agent may assume that such Canadian Lender has made such ratable share available to it on the date of such Drawing in accordance with Section 2.16(a) and the Administrative Agent may, in reliance upon such assumption, make available to the Canadian Borrower on such date a corresponding amount. If and to the extent that any such Canadian Lender shall not have so made such ratable share available to the Administrative Agent, such Canadian Lender and the Canadian Borrower severally agree to repay or pay to the Administrative Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Canadian Borrower until the date such amount is repaid or paid to the Administrative Agent, at (i) in the case of the Canadian Borrower, a rate per annum equal to the BA Rate used in calculating the Drawing Purchase Price with respect to such Drawing, and (ii) in the case of such Canadian Lender, the Canadian Interbank Rate. If such Canadian Lender shall pay to the Administrative Agent such corresponding amount, such amount so paid shall constitute such Canadian Lender’s ratable share of the proceeds of such Drawing for all purposes under this Agreement.

(g) Presigned Draft Forms . To enable the Canadian Lenders which are BA Lenders to create Bankers’ Acceptances in accordance with Section 2.01(c) and this Section 2.16 , the Canadian Borrower intending to make Drawings of Bankers’ Acceptances hereby appoints each BA Lender as its attorney to sign and endorse on its behalf (for the purpose of acceptance and purchase of Bankers’ Acceptances pursuant to this Agreement), in handwriting or by facsimile or mechanical signature as and when deemed necessary by such BA Lender, blank forms of Bankers’ Acceptances. In this respect, it is each BA Lender’s responsibility to maintain an adequate supply of blank forms of Bankers’ Acceptances for acceptance under this Agreement. The Canadian Borrower recognizes and agrees that all Bankers’ Acceptances signed and/or endorsed on its behalf by a BA Lender shall bind the Canadian Borrower as fully and effectually as if signed in the handwriting of and duly issued by the proper signing officers of the Canadian Borrower. Each BA Lender is hereby authorized (for the purpose of acceptance and purchase of Bankers’ Acceptances pursuant to this Agreement) to issue such Bankers’ Acceptances endorsed in blank in such face amounts as may be determined by such BA Lender; provided that the aggregate amount thereof is equal to the aggregate amount of Bankers’ Acceptances required to be accepted and purchased by such BA Lender. On request by the Canadian Borrower, a BA Lender shall cancel all forms of Bankers’ Acceptances which have been pre-signed or pre-endorsed by or on behalf of the Canadian Borrower and which are held by such BA Lender and have not yet been issued in accordance herewith. Each BA Lender further agrees to retain such records in the manner and/or the statutory periods provided in the various Canadian provincial or federal statutes and regulations which apply to such BA Lender. Each BA Lender shall maintain a record with respect to Bankers’ Acceptances held by it in blank hereunder, voided by it for any reason, accepted and purchased by it hereunder, and cancelled at their respective maturities. Each BA Lender agrees to provide such records to the Canadian

Borrower at the Canadian Borrower’s expense upon request. Bankers’ Acceptances shall be signed by a duly authorized officer or officers of the Canadian Borrower or by its attorneys, including its attorneys appointed pursuant to this Section 2.16(g) . Notwithstanding that any person whose signature appears on any Bankers’ Acceptance as a signatory for the Canadian Borrower may no longer be an authorized signatory for the Canadian Borrower at the date of issuance of a Bankers’ Acceptance, such signature shall nevertheless be valid and sufficient for all purposes as if such authority had remained in force at the time of such issuance, and any such Bankers’ Acceptance so signed shall be binding on the Canadian Borrower.

(h) Distribution of Bankers’ Acceptances . Bankers’ Acceptances purchased by a Canadian Lender in accordance with the terms of Section 2.01(c) and this Section 2.16 may, in such Canadian Lender’s sole discretion, be held by such Canadian Lender for its own account until the applicable Maturity Date or sold, rediscounted or otherwise disposed of by it at any time prior thereto in any relevant market therefor.

(i) Failure to Fund in Respect of Drawings . The failure of any Canadian Lender to fund the Drawing Purchase Price to be funded by it as part of any Drawing or to make a BA Equivalent Note shall not relieve any other Canadian Lender of its obligation hereunder to fund its Drawing Purchase Price on the date of such Drawing or to make a BA Equivalent Note, but no Canadian Lender shall be responsible for the failure of any other Canadian Lender to fund the Drawing Purchase Price or make the BA Equivalent Note to be funded or made, as the case may be by such other Canadian Lender on the date of any Drawing.

(j) Optional Renewal/Repayment of Bankers’ Acceptances . The Canadian Borrower shall give notice to the Administrative Agent not later than 11:00 A.M. (Toronto time) on a Business Day at least two Canadian Business Days prior to the Maturity Date of the Bankers’ Acceptances and BA Equivalent Notes comprising part of the same Drawing, and subject to the provisions of Section 2.12 , specifying either that the Canadian Borrower intends to renew all or any portion of such Bankers’ Acceptances and BA Equivalent Notes or that the Canadian Borrower intends to repay such maturing Bankers’ Acceptances and BA Equivalent Notes. Failure by the Canadian Borrower to deliver such notice to the Administrative Agent in accordance with this Section 2.16(j) shall be deemed an election by the Canadian Borrower to repay such Bankers’ Acceptances and BA Equivalent Notes on the applicable Maturity Date.

(k) Renewal of Bankers’ Acceptances . Subject to Section 2.16(j) , the Canadian Borrower may elect to renew Bankers’ Acceptances and BA Equivalent Notes comprising part of the same Drawing, provided , however , that:

(i) any renewal of Bankers’ Acceptances or BA Equivalent Notes shall be made only on the then existing Maturity Date for such Bankers’ Acceptances or BA Equivalent Notes;

(ii) each renewal of Bankers’ Acceptances and BA Equivalent Notes comprising part of the same Drawing shall be made ratably among the Canadian Lenders holding such Bankers’ Acceptances and having made BA Equivalent Notes in accordance with the respective amount of such Bankers’ Acceptances so held and BA Equivalent Notes so made; and

(iii) upon the occurrence and during the continuance of any Event of Default no renewal of any Bankers’ Acceptance or BA Equivalent Notes may be made.

Each such notice of renewal shall, within the restrictions set forth above, specify (A) the date of such renewal (which shall be the then existing Maturity Date of such Bankers’ Acceptances and BA Equivalent

Notes and shall be a Canadian Business Day), (B) the Bankers’ Acceptances to be renewed, (C) if less than all of the Bankers’ Acceptances and BA Equivalent Notes comprising part of any Drawing are to be renewed, the aggregate Face Amount for such renewal and (D) the term to maturity of the renewed Bankers’ Acceptances and BA Equivalent Notes (which shall comply with the definition of “Maturity Date” in Section 1.01 ); provided , however , that, if the Administrative Agent determines in good faith (which determination shall be conclusive and binding upon the Canadian Borrower) that the Bankers’ Acceptances and BA Equivalent Notes cannot, due solely to the requested aggregate Face Amount thereof, be renewed ratably by the Canadian Lenders, the aggregate Face Amount of such renewal (or the Face Amount of Bankers’ Acceptances or BA Equivalent Notes to be created by any Canadian Lender) shall be reduced to such lesser amount as the Administrative Agent determines will permit such renewal to be so made. Each notice of renewal under this Section 2.16 shall be irrevocable and binding on the Canadian Borrower. Upon any renewal of Bankers’ Acceptances and BA Equivalent Notes comprising part of any Drawing in accordance with this Section 2.16(k) , the Canadian Lenders that hold the Bankers’ Acceptances and that made BA Equivalent Notes to be renewed shall exchange such maturing Bankers’ Acceptances for new Bankers’ Acceptances and shall make new BA Equivalent Notes, containing the terms set forth in the applicable notice of renewal, and the Drawing Purchase Price payable for each such renewed Bankers’ Acceptance and the proceeds of the new BA Equivalent Note shall be applied, together with other funds, if necessary, available to the Canadian Borrower, to reimburse the Bankers’ Acceptances and BA Equivalent Notes otherwise maturing on such date. The Canadian Borrower hereby irrevocably authorizes and directs each Canadian Lender to apply the proceeds of each renewed Bankers’ Acceptance or BA Equivalent Note owing to it to the reimbursement, in accordance with this Section 2.16(k) , of the Bankers’ Acceptances or BA Equivalent Notes owing to such Canadian Lender and maturing on such date.

(l) Repayment of Bankers’ Acceptances . Subject to Section 2.16(j) , the Canadian Borrower shall repay on or before 12:00 noon (Toronto time) on the Maturity Date for those Bankers’ Acceptances and BA Equivalent Notes comprising part of the same Drawing, an amount in Canadian Dollars equal to the Face Amount of such Bankers’ Acceptances and BA Equivalent Notes (notwithstanding that a Canadian Lender may be the holder of it at maturity). Any such payment shall satisfy the Canadian Borrower’s obligations under the Bankers’ Acceptances and BA Equivalent Notes to which it relates and the relevant Canadian Lender shall (y) then be solely responsible for the payment of the applicable Bankers’ Acceptances and BA Equivalent Notes, and (z) thereafter indemnify the Canadian Borrower from any loss, cost or expense suffered by or imposed upon the Canadian Borrower in respect of any claim from a holder of such Bankers’ Acceptances and BA Equivalent Notes that the Canadian Borrower is liable for payment thereunder or any payment by the Canadian Borrower in connection with such claim.

(m) Mandatory Conversion . Upon the occurrence and during the continuance of any Event of Default or if the Canadian Borrower shall fail (i) to deliver a properly completed notice of renewal under Section 2.16(j) or (ii) to reimburse the Canadian Lenders for any Bankers’ Acceptances and BA Equivalent Notes comprising part of the same Drawing pursuant to Section 2.16(l) , the Administrative Agent will forthwith so notify the Canadian Borrower and the Canadian Lenders, whereupon each such Bankers’ Acceptance and BA Equivalent Note will automatically, on the then existing Maturity Date of such Bankers’ Acceptance or BA Equivalent Note, convert into a Canadian Prime Rate Advance of the Face Amount of such Bankers’ Acceptance or BA Equivalent Note.

(n) Collateralization of Bankers’ Acceptances . Bankers’ Acceptances and BA Equivalent Notes may not be prepaid. The Canadian Borrower may, however, at its option, exercisable upon not less than one Business Day’s notice to the Administrative Agent, elect to deposit with the Administrative Agent Canadian Dollars in same-day funds to be held by the Administrative Agent, pursuant to collateral arrangements satisfactory to the Administrative Agent, for application to the

payment of any Borrowing of Bankers’ Acceptances or BA Equivalent Notes designated by the Canadian Borrower in such notice. If such a deposit is made, then such Bankers’ Acceptances and BA Equivalent Notes shall be deemed no longer outstanding for purposes of this Agreement; provided that the amount of such deposit shall be not less than the full Face Amount of such Bankers’ Acceptances or BA Equivalent Notes. Furthermore, in the event the maturity of the Bankers’ Acceptances and BA Equivalent Notes is accelerated pursuant to Section 6.01 , the Canadian Borrower shall cash collateralize all outstanding Banker’s Acceptances.

(o) Illegality . Notwithstanding any other provision of this Agreement, if the introduction of or any change in the interpretation of any law or regulation after the date of this Agreement shall make it unlawful, or any central bank or other Governmental Authority shall assert after the date of this Agreement that it is unlawful, for any Canadian Lender or its Canadian Lending Office to perform its obligations hereunder to complete and accept Drafts, to purchase Bankers’ Acceptances or BA Equivalent Notes or to continue to fund or maintain Bankers’ Acceptances or BA Equivalent Notes hereunder, then, on notice thereof and demand therefor by such Canadian Lender to the Borrowers through the Administrative Agent (i) an amount equal to the aggregate Face Amount of all Bankers’ Acceptances and BA Equivalent Notes outstanding at such time shall, upon such demand (which shall only be made if deemed necessary by the applicable Canadian Lender to comply with applicable law), be deposited by the Canadian Borrower with the Administrative Agent in accordance with Section 2.16(n) until the Maturity Date of each such Bankers’ Acceptance and BA Equivalent Note, (ii) upon the Maturity Date of any Bankers’ Acceptance or BA Equivalent Note in respect of which any such deposit has been made, the Administrative Agent shall be, and hereby is, authorized (without notice to or any further action by the Borrowers) to apply, or to direct the Administrative Agent to apply, such amount (or the applicable portion thereof) to the reimbursement of such Bankers’ Acceptance and (iii) the obligation of the Canadian Lenders to complete and accept Drafts and purchase Bankers’ Acceptances and BA Equivalent Note shall be suspended until the Administrative Agent shall notify the Borrowers that such Canadian Lender has determined that the circumstances causing such suspension no longer exist.

(p) Inconsistencies . In the event of any inconsistency between the provisions of this Section 2.16 and any other provision of Article II with respect to Bankers’ Acceptances or BA Equivalent Notes, the provisions of this Section 2.16 shall prevail.

Section 2.17 Mitigation Obligations; Replacement of Lenders .

(a) Designation of a Different Lending Office . If any Lender requests compensation under Section 2.10 , or requires the Borrowers to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14 , then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.10 or Section 2.14 , 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 Company hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders . If any Lender requests compensation under Section 2.10 , or if the Borrowers are required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.14 , and, in each case, such Lender has not designated a different lending office in accordance with Section 2.17(a) , or if any Lender is a Defaulting Lender or a Non-Consenting Lender, then the Company may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to

assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.02 ), all of its interests, rights (other than its existing rights to payments pursuant to Section 2.10 or Section 2.14 ) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if such Lender accepts such assignment); provided that:

(i) the Company shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 9.02 ;

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Advances and participations in Letters of Credit, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 2.02(a)(iii ) or (c)(i)(F) , as applicable) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the applicable Borrower (in the case of all other amounts);

(iii) in the case of any such assignment resulting from a claim for compensation under Section 2.10 or payments required to be made pursuant to Section 2.14 , such assignment will result in a reduction in such compensation or payments thereafter;

(iv) such assignment does not conflict with applicable law; and

(v) in the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Company to require such assignment and delegation cease to apply.

Section 2.18 Cash Collateral . At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative Agent or an Issuing Bank (with a copy to the Administrative Agent), the Company shall Cash Collateralize the Fronting Exposure of the applicable Issuing Bank with respect to such Defaulting Lender (determined after giving effect to Section 2.19(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than 100% of such Fronting Exposure.

(a) Grant of Security Interest . The Company, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of the Issuing Banks, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for the Defaulting Lender’s obligation to fund participations in respect of L/C Obligations, to be applied pursuant to subsection (b) below. If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent and the Issuing Banks as herein provided, or that the total amount of such Cash Collateral is less than 100% of such Fronting Exposure, the Company will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(b) Application . Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 2.18 or Section 2.19 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in

respect of L/C Obligations (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(c) Termination of Requirement . Cash Collateral (or the appropriate portion thereof) provided to reduce the Fronting Exposure of an Issuing Bank shall no longer be required to be held as Cash Collateral pursuant to this Section 2.18 following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by the Administrative Agent and the applicable Issuing Bank that there exists excess Cash Collateral; provided that, subject to Section 2.19 , the Person providing Cash Collateral and the applicable Issuing Bank may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations.

Section 2.19 Defaulting Lenders .

(a) Defaulting Lender Adjustments . Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i) Waivers and Amendments . Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definition of Majority Lenders and Section 10.01 .

(ii) Defaulting Lender Waterfall . Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article VI or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 10.05 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first , to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second , to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Banks; third , to Cash Collateralize the Fronting Exposure of the Issuing Banks with respect to such Defaulting Lender in accordance with Section 2.18 ; fourth , as each Borrower may request (so long as no Default or Event of Default exists), to the funding of any Advance or funded participation in any Letter of Credit in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth , if so determined by the Administrative Agent and the applicable Borrower, to be held in a deposit account and released pro rata in order to (A) satisfy such Defaulting Lender’s potential future funding obligations with respect to Advances and funded participations in Letters of Credit under this Agreement and (B) Cash Collateralize any Issuing Bank’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.18 ; sixth , to the payment of any amounts owing to the Lenders or the Issuing Banks as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Issuing Banks against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh , so long as no Default or Event of Default exists, to the payment of any amounts owing to any Borrower as a result of any judgment of a court of competent jurisdiction obtained by such Borrower against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; and eighth , to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (1) such payment is a payment of the principal amount of any Advances or funded participations in Letters of Credit in respect of which such Defaulting Lender has not fully funded its appropriate share, and (2) such

Advances were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 3.02 were satisfied or waived, such payment shall be applied solely to pay the Advances of, and funded participations in Letters of Credit owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Advances of, or funded participations in Letters of Credit owed to, such Defaulting Lender until such time as all Advances and funded and unfunded participations in L/C Obligations are held by the Lenders pro rata in accordance with the US Commitments without giving effect to Section 2.19(a)(iv) . Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.19(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees .

(A) Each Defaulting Lender shall be entitled to receive a facility fee for any period during which such Lender is a Defaulting Lender only to extent allocable to the sum of (1) the outstanding principal amount of the Advances funded by it, and (2) its Pro Rata Share of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.19 .

(B) Each Defaulting Lender shall be entitled to receive letter of credit commissions pursuant to Section 2.03(b)(i) for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Pro Rata Share of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 2.19 .

(C) With respect to any facility fee or letter of credit commission not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the applicable Borrower shall (1) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in L/C Obligations that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (2) pay to each Issuing Bank, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to such Issuing Bank’s Fronting Exposure to such Defaulting Lender, and (3) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure . All or any part of such Defaulting Lender’s participation in L/C Obligations shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Pro Rata Shares (calculated without regard to such Defaulting Lender’s Pro Rata Share) but only to the extent that (x) the conditions set forth in Section 3.02 are satisfied at the time of such reallocation (and, unless the Company shall have otherwise notified the Administrative Agent at such time, the Company shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate Pro Rata Share of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Pro Rata Share. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v) Cash Collateral . If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Company shall, without prejudice to any right or remedy available to it hereunder or under law, Cash Collateralize the applicable Issuing Bank’s Fronting Exposure in accordance with the procedures set forth in Section 2.18 .

(b) Defaulting Lender Cure . If the applicable Borrower, the Administrative Agent and the applicable Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable, purchase at par that portion of outstanding Advances of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Advances and funded and unfunded participations in Letters of Credit to be held pro rata by the Lenders in accordance with the US Commitments or the Canadian Commitments, as applicable (without giving effect to Section 2.19(a)(iv)) , whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of such Borrower while that Lender was a Defaulting Lender; and provided , further , that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) New Letters of Credit . So long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

(e) The consolidated balance sheet of the Company and its Subsidiaries as at December 31, 2011, and the related consolidated statements of income and cash flows of the Company and its Subsidiaries for the fiscal year then ended, accompanied by an opinion of KPMG LLP, independent public accountants, fairly present the consolidated financial condition of the Company and its Subsidiaries as at such date and the consolidated results of the operations of the Company and its Subsidiaries for the period ended on such date, all in accordance with GAAP. Except as publicly disclosed prior to the date hereof, on and as of the date of this Agreement, since December 31, 2011, there has been no material adverse change in the business, financial condition or results of operations of the Company and its Subsidiaries, taken as a whole.

(f) There are no actions, suits or proceedings pending or, to the knowledge of the Company, threatened, against the Company or any Subsidiary the reasonably anticipated outcome of which (i) would materially and adversely affect the ability of any Borrower to perform its obligations under the Loan Documents or (ii) purport to affect the legality, validity or enforceability of any Loan Document.

(g) No Borrower is engaged in the business of extending credit for the purpose of purchasing or carrying Margin Stock, and no proceeds of any Advance will be used to purchase or carry any Margin Stock or to extend credit to others for the purpose of purchasing or carrying any Margin Stock, except in compliance with Regulations T, U and X issued by the Board of Governors of the Federal Reserve Board.

(h) Neither the Company nor any Subsidiary is an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940.

(i) The Company and each Subsidiary have filed all material Tax returns (federal, state, provincial and local) required to be filed and paid all taxes shown thereon to be due, including interest and penalties, or provided adequate reserves for payment thereof.

(j) In the ordinary course of its business, the Company conducts an ongoing review of the effect of Environmental Laws on the operations and properties of the Company, in the course of which it identifies and evaluates associated liabilities and costs (including, without limitation, any capital or operating expenditures required for clean-up or closure of properties presently or previously owned, any liabilities in connection with off-site disposal of Hazardous Substances and any capital or operating expenditures) required to achieve or maintain compliance with Environmental Laws. On the basis of this review, the Company has reasonably concluded that, except with respect to any matter disclosed in Items 1 or 3 in the Company’s 2011 Form 10-K or in the Commitments and Contingencies Note to the consolidated financial statements incorporated therein, such associated liabilities and costs, are unlikely to cause a material adverse change in the business, financial condition or results of operations of the Company and its Subsidiaries, taken as a whole, from that shown on the consolidated financial statements as at, and for the fiscal year ended December 31, 2011, provided that the inclusion of such exception does not indicate that any such matter will cause such a material adverse change.

THE AGENT

Except to the extent expressly provided in Section 8.07 , the provisions of this Article are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Banks, and neither the Borrowers nor of their respective Subsidiaries shall have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

Section 8.02 Reliance by the Administrative Agent . The Administrative Agent 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 (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of an Advance, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or an Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to such Lender or such Issuing Bank unless the Administrative Agent shall have received notice to the contrary from such Lender or such Issuing Bank prior to the making of such Advance or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrowers), 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.

Section 8.03 Rights as a Lender . The Person serving as the Administrative 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 the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrowers or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

Section 8.04 Exculpatory Provisions .

(ii) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Majority Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law; and

(iii) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrowers or any of their respective Subsidiaries or Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

(b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 6.01 and Section 10.01 ) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default or Event of Default unless and until notice describing such Default or Event of Default is given to the Administrative Agent by the Company, a Lender or an Issuing Bank.

(c) The Administrative 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 this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article III or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

Section 8.05 Non-Reliance on Administrative Agent and Other Lenders . Each Lender and each Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Lender, any other Issuing Bank or any of their Related Parties, and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and each Issuing Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Lender, any other Issuing Bank or any of their Related Parties, 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.

Section 8.06 Indemnification . (a) Each Lender severally agrees to indemnify the Administrative Agent (to the extent not reimbursed by the Company), from and against such Lender’s ratable share of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any action taken or omitted by the Administrative Agent under this Agreement (collectively, the “ Indemnified Costs ”), provided that no Lender shall be liable for any portion of the Indemnified Costs resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, to the extent that the Administrative Agent is not reimbursed for such expenses by the Company. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 8.06 applies whether any such investigation, litigation or proceeding is brought by the Administrative Agent, any Lender or a third party.

(b) Each US Lender severally agrees to indemnify each Issuing Bank (to the extent not promptly reimbursed by the Company) from and against such Lender’s ratable share (determined as provided below) of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Issuing Bank in any way relating to or arising out of this Agreement or any action taken or omitted by such Issuing Bank hereunder or in connection herewith; provided , however , that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Issuing Bank’s gross negligence or willful misconduct as found in a final, non-appealable judgment by a court of competent jurisdiction. Without limitation of the foregoing, each US Lender agrees to reimburse each Issuing Bank promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Company under Section 10.04 , to the extent that the Issuing Bank is not promptly reimbursed for such costs and expenses by the Company.

(c) For purposes of this Section 8.06 , the Lenders’ respective ratable shares of any amount shall be determined, at any time, according to the sum of (i) the aggregate principal amount of the Revolving Advances outstanding at such time and owing to the respective Lenders, (ii) their respective Pro Rata Shares of the aggregate Available Amount of all Letters of Credit outstanding at such time and (iii) their respective Unused Canadian Commitments and Unused US Commitments at such time; provided that the aggregate principal amount of Revolving Advances made as a result of a drawing under a Letter of Credit owing to the Issuing Bank shall be considered to be owed to the Lenders ratably in accordance with their respective US Commitments. The failure of any Lender to reimburse the Administrative Agent or the Issuing Bank, as the case may be, promptly upon demand for its ratable share of any amount required to be paid by the Lenders to such Administrative Agent or the Issuing Bank, as the case may be, as provided herein shall not relieve any other Lender of its obligation hereunder to reimburse such Administrative Agent or Issuing Bank, as the case may be, for its ratable share of such amount, but no Lender shall be responsible for the failure of any other Lender to reimburse the Administrative Agent or the Issuing Bank, as the case may be, for such other Lender’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender hereunder, the

agreement and obligations of each Lender contained in this Section 8.06 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the Notes.

If no successor Administrative Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States or of any State thereof and having a combined capital and surplus of at least US$500,000,000.

After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent, the provisions of this Article VIII shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement.

Each Lender demanding payment of such amount shall provide, at the time of making such demand, the applicable Borrower and the Administrative Agent with reasonable details, including the basis for the calculation thereof, of such increase, provided that, in the absence of manifest error, the amount so notified shall be conclusive and binding upon such Borrower.

(c) Each party’s obligations under this Section shall survive the termination of the Loan Documents and payment of the obligations hereunder.

Section 10.05 Right of Set-off .

the credit or the account of any Borrower against any and all of the obligations of such Borrower now or hereafter existing under this Agreement and the other Loan Documents whether or not such Lender shall have made any demand under this Agreement or the Note held by such Lender and although such obligations may be unmatured. Each Lender agrees promptly to notify the applicable Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set¬off and application.

Section 10.06 Indemnification by Company . The Company agrees to indemnify and hold harmless the Administrative Agent and each Lender (and each of their respective officers, agents, employees and directors) (each, an “ Indemnified Party ”) from and against any and all claims, damages, liabilities, obligations, losses, penalties, actions, judgments, suits, costs, expenses and disbursements (including, without limitation, reasonable fees and disbursements of outside counsel) of any kind or nature whatsoever (“ Claims ”) which may be imposed on, incurred by or asserted against such Lender or any of its officers, agents, employees or directors (but excluding Claims of any Person resulting from such Person’s gross negligence or willful misconduct) in connection with or arising out of any investigation, litigation or proceeding (including, without limitation, any threatened investigation, litigation or proceeding or preparation of a defense in connection therewith) related to the Notes, this Agreement, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances, except to the extent such claim, damage, loss, liability or expense resulted from such Indemnified Party’s gross negligence or willful misconduct.

Each Borrower also agrees not to assert any claim for special, indirect, consequential or punitive damages against the Administrative Agent, any Lender, any of their Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability, arising out of or otherwise relating to this Agreement or any of the other Loan Documents or any agreement or instrument contemplated hereby, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances or Letters of Credit.

For the purposes of this Section, “ Confidential Information ” means all information, including material nonpublic information with the meaning of Regulation FD promulgated by the SEC (“ Regulation FD ”), received from the Company or its Subsidiaries relating to such entities or their respective businesses, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by such entities; provided , that such information is clearly identified at the time of delivery as confidential.

(a) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder in one currency into another currency, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Administrative Agent could purchase the first currency with such other currency at Citibank’s principal office in London at 11:00 A.M. (London time) on the Business Day preceding that on which final judgment is given.

(b) The obligation of any Borrower in respect of any sum due from it in any currency (the “ Primary Currency ”) to any Lender or the Administrative Agent hereunder shall, notwithstanding any judgment in any other currency, be discharged only to the extent that on the Business Day following receipt by such Lender or the Administrative Agent (as the case may be), of any sum adjudged to be so due in such other currency, such Lender or the Administrative Agent (as the case may be) may in accordance with normal banking procedures purchase the applicable Primary Currency with such other currency; if the amount of the applicable Primary Currency so purchased is less than such sum due to such Lender or the Administrative Agent (as the case may be) in the applicable Primary Currency, each Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Lender or the Administrative Agent (as the case may be) against such loss, and if the amount of the applicable Primary Currency so purchased exceeds such sum due to any Lender or the Administrative Agent (as the case may be) in the applicable Primary Currency, such Lender or the Administrative Agent (as the case may be) agrees to remit to such Borrower such excess.
