Except with respect to Loans made pursuant to Section 2.02(f), each Canadian Lender making Loans to the Canadian Borrower shall make each Canadian Loan (other than Canadian Loans described in the preceding sentence) to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds to such account in Toronto, Ontario, as the Canadian Administrative Agent may designate not later than 11:00 a.m., Standard Time, in the case of a Eurocurrency Borrowing or a B/A Borrowing, or 1:00 p.m., Standard Time, in the case of a Canadian Prime Rate Borrowing or U.S. Base Rate Borrowing, and the Canadian Administrative Agent shall promptly credit the amounts so received to an account designated by the Canadian Borrower in the applicable Borrowing Request. (d) Unless the Applicable Administrative Agent shall have received notice from a Lender prior to the time of any Borrowing that such Lender will not make available to the Applicable Administrative Agent such Lender's portion of such Borrowing, the Applicable Administrative Agent may assume that such Lender has made such portion available to the Applicable Administrative Agent on the date of such Borrowing in accordance with paragraph (c) above and the Applicable Administrative Agent may, in reliance upon such assumption, make available to the applicable Borrower on such date a corresponding amount. If the Applicable Administrative Agent shall have so made funds available then, to the extent that such Lender shall not have made such portion available to the Applicable Administrative Agent, such Lender and the applicable Borrower severally agree to repay to the Applicable 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 applicable Borrower until the date such amount is repaid to the Applicable Administrative Agent at (i) in the case of a Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Lender, a rate determined by the Applicable Administrative Agent to represent its cost of overnight or short-term funds in the applicable currency (which determination 30 shall be conclusive absent manifest error). If such Lender shall repay to the Applicable Administrative Agent such corresponding amount, such amount shall constitute such Lender's Loan as part of such Borrowing for purposes of this Agreement; provided, however, that the foregoing does not constitute a waiver by either Borrower of any claim for damages permitted hereunder and attributable to such Lender. (e) Notwithstanding any other provision of this Agreement, the Borrowers shall not be entitled to request any Borrowing if the Interest Period or Contract Period requested with respect thereto would end after the Maturity Date. (f) If an Issuing Bank shall not have received from the U.S. Borrower or the Canadian Borrower, as the case may be, the payment required to be made by Section 2.21(e) within the time specified in such Section, such Issuing Bank will promptly notify the Applicable Administrative Agent of the L/C Disbursement and the Applicable Administrative Agent will promptly notify each U.S. Lender or Canadian Lender, as applicable, of such L/C Disbursement and its U.S. Pro Rata Percentage or Canadian Pro Rata Percentage, as applicable, thereof. Each such Lender shall pay by wire transfer of immediately available funds to the Applicable Administrative Agent not later than 2:00 p.m., Standard Time, on such date (or, if such Lender shall have received such notice later than 12:00 (noon), Standard Time, on any day, not later than 11:00 a.m., Standard Time, on the immediately following Business Day), an amount equal to such Lender's U.S. Pro Rata Percentage or Canadian Pro Rata Percentage, as applicable, of such L/C Disbursement (it being understood that such amount shall be deemed to constitute an ABR Loan or a Canadian Prime Rate Loan, as applicable, of such Lender and such payment shall be deemed to have reduced the U.S. L/C Exposure or the Canadian L/C Exposure, as applicable), and the Applicable Administrative Agent will promptly pay to such Issuing Bank amounts so received by it from such Lenders. The Applicable Administrative Agent will promptly pay to such Issuing Bank any amounts received by it from a Borrower pursuant to Section 2.21(e) prior to the time that any Lender makes any payment pursuant to this paragraph (f); any such amounts received by the Applicable Administrative Agent thereafter will be promptly remitted by the Applicable Administrative Agent to the Lenders that shall have made such payments and to such Issuing Bank, as their interests may appear. If any Lender shall not have made its U.S. Pro Rata Percentage or Canadian Pro Rata Percentage, as applicable, of such L/C Disbursement available to the Applicable Administrative Agent as provided above, such Lender and the Borrower for whose account such L/C Disbursement was made severally agree to pay interest on such amount, for each day from and including the date such amount is required to be paid in accordance with this paragraph to but excluding the date such amount is paid, to the Applicable Administrative Agent for the account of such Issuing Bank at (i) in the case of such Borrower, a rate per annum equal to the interest rate applicable to Loans pursuant to Section 2.06(a) or 2.06(c), as the case may be, and (ii) in the case of such Lender, for the first such day, the rate determined by the Applicable Administrative Agent to represent its cost of obtaining overnight or short-term funds in the relevant currency (which determination shall be conclusive absent manifest error), and for each day thereafter, the Alternate Base Rate or the Canadian Prime Rate, as the case may be; provided, however, that the foregoing does not constitute 31 a waiver by either Borrower of any claim for damages permitted hereunder and attributable to such Lender.

If no Contract Period or Interest Period with respect to a B/A Borrowing or Eurocurrency Borrowing has been specified in any such notice, then the Canadian Borrower shall be deemed to have selected a Contract Period or Interest Period of 30 days' or one month's duration, respectively. The Canadian Administrative Agent shall promptly advise the applicable Lenders of any notice given pursuant to this Section 2.03(b) (and the contents thereof), and of each Lender's portion of the requested Borrowing. SECTION 2.04. EVIDENCE OF DEBT; REPAYMENT OF LOANS. (a) The U.S. Borrower hereby unconditionally promises to pay to the Administrative Agent (i) for the account of each U.S. Lender holding U.S. Loans, and (ii) for the account of each Canadian Lender holding Canadian Loans denominated in U.S. dollars and made to the U.S. Borrower, the then unpaid principal amount of each such Loan of such Lender on the Maturity Date. The Canadian Borrower hereby unconditionally promises to pay to the Canadian Administrative Agent for the account of each Canadian Lender holding Canadian Loans made to the Canadian Borrower, the then unpaid principal amount of each such Loan of such Canadian Lender on the Maturity Date. Except for any B/A Loan (the compensation for which is set forth in Section 2.22), each Loan shall bear interest from and including the date made on the outstanding principal balance thereof as set forth in Section 2.06. (b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrowers to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid such Lender from time to time under this Agreement. (c) The Administrative Agents shall maintain accounts in which they will record (i) the amount of each Loan made hereunder, the Type and currency thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the applicable Borrower to each Lender hereunder and (iii) the amount of any sum received by the Applicable Administrative Agent hereunder from either Borrower or any Subsidiary Guarantor and each Lender's share thereof. (d) The entries made in the accounts maintained pursuant to paragraphs (b) and (c) above shall be prima facie evidence of the existence and amounts of the obligations therein recorded; provided, however, that the failure of any Lender or the Administrative Agents to maintain such accounts or any error therein shall not in any manner affect the obligations of the Borrowers to repay the Loans in accordance with the terms of this Agreement. 33 (e) Any Lender may request that Loans made by it hereunder be evidenced by a promissory note. In such event, the applicable Borrower shall execute and deliver to such Lender a promissory note or promissory notes payable to such Lender and its registered assigns and in a form and substance reasonably acceptable to the Applicable Administrative Agent and the applicable Borrower. Notwithstanding any other provision of this Agreement, in the event any Lender shall request and receive such a promissory note, the interests represented by such note shall at all times (including after any assignment of all or part of such interests pursuant to Section 9.04) be represented by one or more promissory notes payable to the payee named therein or its registered assigns. SECTION 2.05. FEES. (a) Each Borrower agrees to pay to each Lender, through the Applicable Administrative Agent, on the last Business Day of March, June, September and December in each year, commencing on the last Business Day of December 2003, and on each date on which any Commitment of such Lender shall expire or be terminated as provided herein, a commitment fee (a "Commitment Fee") equal to the Applicable Percentage on the daily unused amount of the Commitments of such Lender to make Loans to such Borrower during the preceding quarter (or other period commencing with the Closing Date or ending with the Maturity Date or the date on which the Commitments of such Lender shall expire or be terminated). All Commitment Fees shall be computed on the basis of the actual number of days elapsed in a year of 360 days. The Commitment Fees due to each Lender shall commence to accrue on the Closing Date, and shall cease to accrue on the date on which the applicable Commitment of such Lender shall expire or be terminated as provided herein. (b) Each Borrower agrees to pay to the Applicable Administrative Agent, for its own account, the administration fees separately agreed to from time to time by such Borrower and such Administrative Agent, including, without limitation, the fees set forth in the Administrative Agent Fee Letter (the "Administrative Agent Fees"). (c) Each Borrower agrees to pay (i) to each Lender, through the Applicable Administrative Agent, on the last Business Day of March, June, September and December of each year, commencing on the last Business Day of December 2003, and on the date on which the Commitment of such Lender shall be terminated as provided herein, a fee (an "L/C Participation Fee") calculated on such Lender's U.S. Pro Rata Percentage or Canadian Pro Rata Percentage, as applicable, of the daily aggregate U.S. L/C Exposure or Canadian L/C Exposure, as applicable (in each case excluding the portion thereof attributable to unreimbursed L/C Disbursements in respect of Letters of Credit) during the preceding quarter (or shorter period commencing with the Closing Date or ending with the Maturity Date or the date on which all Letters of Credit have been canceled or have expired and the Commitments of all Lenders shall have been terminated) at a rate equal to the Applicable Percentage from time to time used to determine the interest rate on Borrowings comprised of Eurocurrency Loans pursuant to Section 2.06, and (ii) to the Applicable Issuing Bank with respect to each Letter of Credit, (A) a fronting fee for each Letter of Credit equal to the greater of (1) 0.125% of the initial stated amount of such Letter of Credit and (2) $600 (or, with respect to any subsequent increase to the stated amount of any such Letter of Credit, such increase in the stated amount) thereof, such fee to be payable on the date of such issuance, increase or 34 extension and (B) issuance, payment, amendment and transfer fees specified from time to time by such Issuing Bank (collectively, the "Issuing Bank Fees"). All L/C Participation Fees and, unless otherwise agreed by the Applicable Issuing Bank, Issuing Bank Fees, shall be computed on the basis of the actual number of days elapsed in a year of 360 days. (d) All Fees shall be paid on the dates due, in immediately available U.S. dollars (except with respect to L/C Participation Fees and Issuing Bank Fees in respect of Canadian Letters of Credit, each of which shall be payable in immediately available Canadian dollars), to the Applicable Administrative Agent for distribution, if and as appropriate, among the Lenders, except that the Issuing Bank Fees shall be paid directly to the Applicable Issuing Bank. Once paid, absent manifest error, none of the Fees shall be refundable under any circumstances. SECTION 2.06. INTEREST ON LOANS. (a) Subject to the provisions of Sections 2.07 and 9.09, the Loans comprising each ABR Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, when the Alternate Base Rate is determined by reference to the Prime Rate and over a year of 360 days at all other times and calculated from and including the date of such Borrowing to but excluding the date of repayment thereof) at a rate per annum equal to the Alternate Base Rate plus the Applicable Percentage in respect of ABR Loans in effect from time to time. (b) Subject to the provisions of Sections 2.07 and 9.09, the Loans comprising each Eurocurrency Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 360 days) at a rate per annum equal to the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Percentage in respect of Eurocurrency Loans in effect from time to time. (c) Subject to the provisions of Sections 2.07 and 9.09, the Loans comprising each Canadian Prime Rate Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, and calculated from and including the date of such Borrowing to but excluding the date of repayment thereof) at a rate per annum equal to the Canadian Prime Rate plus the Applicable Percentage in respect of the Canadian Prime Rate Loans in effect from time to time. (d) Subject to the provisions of Sections 2.07 and 9.09, the Loans comprising each B/A Borrowing shall be subject to an Acceptance Fee, payable by the Canadian Borrower on the date of acceptance of the relevant B/A and calculated as set forth in the definition of the term "Acceptance Fee" in Section 1.01. (e) Subject to the provisions of Sections 2.07 and 9.09, the Loans comprising each U.S. Base Rate Borrowing shall bear interest (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, and calculated from and including the date of such Borrowing to but excluding the date of repayment thereof) 35 at a rate per annum equal to the U.S. Base Rate plus the Applicable Percentage in respect of U.S. Base Rate Loans in effect from time to time. (f) Interest on each Loan shall be payable to the Applicable Administrative Agent on the Interest Payment Dates applicable to such Loan except as otherwise provided in this Agreement. The applicable Alternate Base Rate, Adjusted LIBO Rate, Canadian Prime Rate, U.S. Base Rate, Discount Rate, and Acceptance Fee shall be determined by the Applicable Administrative Agent, and such determination shall be conclusive absent manifest error. (g) For the purposes of the Interest Act (Canada) and disclosure thereunder, whenever any interest or fee to be paid hereunder or in connection herewith is to be calculated on the basis of any period of time that is less than a calendar year, the yearly rate of interest to which the rate used in such calculation is equivalent is the rate so used multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by 360, 365 or 366, as applicable. The rates of interest under this Agreement are nominal rates, and not effective rates or yields. The principle of deemed reinvestment of interest does not apply to any interest calculation under this Agreement. SECTION 2.07. DEFAULT INTEREST. If a Borrower shall default in the payment of the principal of or interest on any Loan or any other amount becoming due hereunder, by acceleration or otherwise, or under any other Loan Document, such Borrower shall on demand from time to time pay interest, to the extent permitted by law, on such defaulted amount to but excluding the date of actual payment (after as well as before judgment) (a) in the case of overdue principal, at the rate otherwise applicable to such Loan pursuant to Section 2.06 plus 2.00% per annum (subject to Section 9.09) and (b) in all other cases, at a rate per annum (computed on the basis of the actual number of days elapsed over a year of 365 or 366 days, as the case may be, when determined by reference to the Prime Rate or the Canadian Prime Rate and over a year of 360 days at all other times) equal to the rate that would be applicable to an ABR Loan (or a Canadian Prime Rate Loan, in the case of the Canadian Borrower) plus 2.00% (subject to Section 9.09). SECTION 2.08. ALTERNATE RATE OF INTEREST. In the event, and on each occasion, that on the day two Business Days prior to the commencement of any Interest Period for a Eurocurrency Borrowing the Administrative Agent shall have determined that dollar deposits in the principal amounts of the Loans comprising such Borrowing are not generally available in the London interbank market, or that the rates at which such dollar deposits are being offered will not adequately and fairly reflect the cost to any Lender of making or maintaining its Eurocurrency Loan during such Interest Period, or that reasonable means do not exist for ascertaining the Adjusted LIBO Rate, the Administrative Agent shall, as soon as practicable thereafter, give written or fax notice of such determination to the Borrowers and the Lenders. In the event of any such determination, until the Administrative Agent shall have advised the Borrowers and the Lenders that the circumstances giving rise to such notice no longer exist, any request by a Borrower for a Eurocurrency Borrowing pursuant to Section 2.03 or 2.10 shall be deemed to be a request for an ABR Borrowing (or, in the case of a request by the Canadian 36 Borrower, a U.S. Base Rate Borrowing). Each determination by the Administrative Agent hereunder shall be conclusive absent manifest error. SECTION 2.09. TERMINATION AND REDUCTION OF COMMITMENTS. (a) The Commitments and the L/C Commitments shall automatically terminate on the Maturity Date. (b) Upon at least three Business Days' prior irrevocable written or fax notice to the Administrative Agents, the U.S. Borrower or the Canadian Borrower, as the case may be, may at any time in whole permanently terminate, or from time to time in part permanently reduce, any Class of Commitments; provided, however, that each partial reduction of any Class of Commitments shall be in an integral multiple of U.S.$1,000,000, or C$1,000,000, as the case may be. (c) Each reduction in any Class of Commitments hereunder shall be made ratably among the Lenders in accordance with their respective Commitments of such Class. The applicable Borrower shall pay to the Applicable Administrative Agent for the account of the applicable Lenders, on the date of each termination or reduction, the Commitment Fees on the amount of the Commitments so terminated or reduced accrued to but excluding the date of such termination or reduction. (d) The Borrowers may, by notice to the Administrative Agent (which shall promptly deliver a copy to each of the Lenders) given not less than 45 days prior to the Maturity Date at any time in effect, request that the Lenders extend the Maturity Date for an additional period of not more than one year as specified in such notice. Each Lender shall, by notice to the Borrowers and the Administrative Agent given not later than 30 days following receipt of the Borrowers' request, advise the Borrowers whether or not it agrees to such extension. Any Lender that has not so advised the Borrowers and the Administrative Agent by such day shall be deemed to have declined to agree to such extension. If the Borrowers shall have requested and if each Lender shall have agreed to an extension of the Maturity Date, then the Maturity Date shall be extended for the additional period specified in the Borrowers' request. The decision to agree or withhold agreement to any extension of the Maturity Date hereunder shall be at the sole discretion of each Lender. Notwithstanding the foregoing provisions of this paragraph, (i) the Maturity Date may not be extended to a date later than October 29, 2008, pursuant to this paragraph, (ii) the Borrowers shall have the right, pursuant to Section 2.20(a), to replace any Lender (a "Non-Consenting Lender") that has declined to agree to any requested extension of the Maturity Date with a Lender or other financial institution that will agree to such extension of the Maturity Date, (iii) if Lenders holding at least 66 2/3% but less than 100% of the Commitments of a Class shall have agreed to such requested extension, the applicable Borrower may repay or prepay, on a non-pro rata basis, the Loans (together with accrued and unpaid interest and Fees), and terminate the Commitments, of the Non-Consenting Lenders of such Class (provided that the Total Commitment immediately after giving effect to such termination shall not be less than U.S.$166,666,666.67) and (iv) the Borrowers shall have the right, any time prior to the Maturity Date then in effect, to withdraw their request for an extension under this paragraph by notice to the Administrative Agent (which shall promptly deliver a notice to 37 each Lender), in which case the Maturity Date will not be so extended. Notwithstanding anything herein to the contrary, (A) the Maturity Date shall not be extended unless the Borrower shall have either (y) replaced a Non-Consenting Lender with a Lender or other financial institution that will agree to such extension and that has assumed all of such Non-Consenting Lender's Credit Exposure or (z) made repayments or prepayments on all outstanding Loans of such Non-Consenting Lender, unreimbursed amounts on account of payments made by such Non-Consenting Lender pursuant to Section 2.02(f) and all interest, fees and other amounts accrued for the account of such Non-Consenting Lender; and (B) immediately upon the extension of the Maturity Date, each Non-Consenting Lender shall be released from its obligations under this Agreement (other than under Section 9.16 with respect to Information previously delivered to it), including, without limitation, its obligations under Section 2.21(d) and such Lender shall cease to be a party hereto and shall have no Credit Exposure hereunder, but shall continue to be entitled to the benefits of Section 2.13, 2.15, 2.19 and 9.05 as well as to any Fees accurred for its account and not yet paid. SECTION 2.10. CONVERSION AND CONTINUATION OF BORROWINGS. The Borrowers shall have the right at any time upon prior irrevocable notice to the Applicable Administrative Agent (a) not later than 11:00 a.m., Standard Time, on the day of the proposed conversion, to convert any Eurocurrency Borrowing into an ABR Borrowing under the U.S. Commitments or the Canadian Commitments, (b) not later than 3:00 p.m., Standard Time, one Business Day before the proposed conversion to convert any U.S. Base Rate Borrowing under the Canadian Commitments or to convert any B/A Borrowing into a Canadian Prime Rate Borrowing, (c) not later than 1:00 p.m., Standard Time, three Business Days prior to conversion or continuation, to convert any ABR Borrowing or U.S. Base Rate Borrowing into a Eurocurrency Borrowing or to continue any Eurocurrency Borrowing as a Eurocurrency Borrowing for an additional Interest Period, (d) not later than 1:00 p.m., Standard Time, three Business Days prior to conversion, to convert the Interest Period with respect to any Eurocurrency Borrowing to another permissible Interest Period and (e) not later than 1:00 p.m., Standard Time, three Business Days prior to conversion or continuation, to convert any Canadian Prime Rate Borrowing to a B/A Borrowing or to continue any B/A Borrowing as a B/A Borrowing for an additional Contract Period, subject in each case to the following: (i) each conversion or continuation shall be made pro rata among the Lenders in accordance with the respective principal amounts of the Loans comprising the converted or continued Borrowing; (ii) if less than all the outstanding principal amount of any Borrowing shall be converted or continued, then each resulting Borrowing shall satisfy the limitations specified in Sections 2.02(a) and 2.02(b) and, if applicable, Section 2.22, regarding the principal amount and maximum number of Borrowings of the relevant Type; (iii) each conversion shall be effected by each Lender and the Applicable Administrative Agent by recording for the account of such Lender the new Type and/or Interest Period or Contract Period for such Borrowing resulting from such 38 conversion; accrued interest on any Eurocurrency Loan (or portion thereof) being converted shall be paid by the applicable Borrower at the time of conversion; (iv) if any Eurocurrency Borrowing or B/A Borrowing is converted at a time other than the end of the Interest Period applicable thereto, the applicable Borrower shall pay, upon demand, any amounts due to the Lenders pursuant to Section 2.15; (v) any portion of a Borrowing maturing or required to be repaid in less than one month may not be converted into or continued as a Eurocurrency Borrowing or a B/A Borrowing; (vi) any portion of a Eurocurrency Borrowing or a B/A Borrowing that cannot be converted into or continued as a Eurocurrency Borrowing or a B/A Borrowing by reason of the immediately preceding clause shall be automatically converted at the end of the Interest Period or Contract Period in effect for such Borrowing into an ABR Borrowing, a U.S. Base Rate Borrowing or a Canadian Prime Rate Borrowing, as the case may be; and (vii) upon notice to the Borrowers from the Administrative Agent given at the request of the Required U.S. Lenders or the Required Canadian Lenders, as the case may be, after the occurrence and during the continuance of a Default or Event of Default, no outstanding Loan may be converted into, or continued as, a Eurocurrency Loan or a B/A Loan, respectively. Each notice pursuant to this Section 2.10 shall be irrevocable and shall refer to this Agreement and specify (i) the identity and amount of the Borrowing that the applicable Borrower requests be converted or continued, (ii) whether such Borrowing is to be converted to or continued as a Eurocurrency Borrowing, an ABR Borrowing, a B/A Borrowing, a U.S. Base Rate Borrowing or a Canadian Prime Rate Borrowing, (iii) if such notice requests a conversion, the date of such conversion (which shall be a Business Day) and (iv) if such Borrowing is to be converted to or continued as a Eurocurrency Borrowing or a B/A Borrowing, the Interest Period or Contract Period with respect thereto. If no Interest Period or Contract Period is specified in any such notice with respect to any conversion to or continuation as a Eurocurrency Borrowing or a B/A Borrowing, the applicable Borrower shall be deemed to have selected an Interest Period or Contract Period of one month's or 30 days', as the case may be, duration. The Applicable Administrative Agent shall promptly advise the applicable Lenders of any notice given pursuant to this Section 2.10 and of each Lender's portion of any converted or continued Borrowing. If a Borrower shall not have given notice in accordance with this Section 2.10 to continue any Eurocurrency or B/A Borrowing into a subsequent Interest Period or Contract Period (and shall not otherwise have given notice in accordance with this Section 2.10 to convert such Borrowing), such Borrowing shall, at the end of the Interest Period applicable thereto (unless repaid pursuant to the terms hereof), automatically be converted into an ABR Borrowing, a U.S. Base Rate Borrowing or a Canadian Prime Rate Borrowing, as applicable. 39 SECTION 2.11. OPTIONAL PREPAYMENT. (a) Each Borrower shall have the right at any time and from time to time to prepay any Borrowing (other than Bankers' Acceptances or B/A Equivalent Loans, which may, however, be defeased as provided below), in whole or in part, upon written or telecopy notice (or telephone notice promptly confirmed by written or telecopy notice) delivered to the Applicable Administrative Agent (i) by 1:00 p.m., Standard Time, at least three Business Days prior to the date designated for such prepayment, in the case of any prepayment of a Eurocurrency Borrowing, (ii) by 11:00 a.m., Standard Time, on the date designated for such prepayment in the case of any prepayment of an ABR Borrowing under the U.S. Commitments, or (iii) by 3:00 p.m., Standard Time, one Business Day prior to the date designated for such prepayment, in the case of an ABR Borrowing, a U.S. Base Rate Borrowing or a Canadian Prime Rate Borrowing under the Canadian Commitments; provided, however, that each partial prepayment shall be in an amount that is a minimum amount of U.S.$500,000 or an integral multiple of U.S.$100,000 in excess thereof (or C$500,000 and C$100,000, respectively, in the case of Borrowings denominated in Canadian dollars); and provided further that the Canadian Borrower may defease any B/A or B/A Equivalent Loan by depositing with the Canadian Administrative Agent an amount that, together with interest accruing on such amount to the end of the Contract Period for such B/A or B/A Equivalent Loan is sufficient to pay such maturing Bankers' Acceptances or B/A Equivalent Loans when due. The Applicable Administrative Agent shall promptly advise the applicable Lenders of any notice given pursuant to this Section 2.11 and of each Lender's portion of such prepayment. (b) Each notice of prepayment shall specify (i) the amount to be prepaid, (ii) the prepayment date and (iii) the Class of Loans to be repaid and shall commit the applicable Borrower to prepay such obligations by the amount specified therein on the date specified therein. All prepayments pursuant to this Section 2.11 shall be subject to Section 2.15, but shall otherwise be without premium or penalty. SECTION 2.12. MANDATORY PREPAYMENTS. In the event of any termination of all the U.S. Commitments or Canadian Commitments, the applicable Borrower shall, on the date of such termination, repay or prepay all its outstanding Borrowings and replace all outstanding Letters of Credit and/or deposit an amount equal to the sum of the U.S. L/C Exposure and the Canadian L/C Exposure in cash in a cash collateral account established with the Collateral Agent for the benefit of the Secured Parties. In the event of any partial reduction of the U.S. Commitments or the Canadian Commitments, then (i) at or prior to the effective date of such reduction, the Administrative Agent shall notify the Borrowers and the Lenders of the aggregate U.S. Credit Exposure or the aggregate Canadian Credit Exposure, as the case may be, after giving effect thereto, and (ii) if the aggregate U.S. Credit Exposure or the aggregate Canadian Credit Exposure, as the case may be, would exceed the Total U.S. Commitment or Total Canadian Commitment, respectively, after giving effect to such reduction, then the U.S. Borrower or the Canadian Borrower, as the case may be, shall, on the date of such reduction, repay or prepay Borrowings (or defease B/A Borrowings as described in Section 2.11(a)) and/or replace or cash collateralize outstanding Letters of Credit in an amount sufficient to eliminate such excess. If on any Calculation Date, the aggregate Canadian Credit Exposure would exceed the Total Canadian Commitment, then on the immediately succeeding Reset Date the Canadian 40 Borrower shall repay or prepay Canadian Borrowings (or defease B/A Borrowings as described in Section 2.11(a)) and/or replace or cash collateralize outstanding Canadian Letters of Credit in an amount sufficient to eliminate such excess. SECTION 2.13. RESERVE REQUIREMENTS; CHANGE IN CIRCUMSTANCES. (a) Notwithstanding any other provision of this Agreement, if any Change in Law shall impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of or credit extended by any Lender or Issuing Bank (except any such reserve requirement which is reflected in the Adjusted LIBO Rate or Discount Rate) or shall impose on such Lender or Issuing Bank or the London interbank market or other relevant interbank market any other condition affecting this Agreement or Eurocurrency Loans or B/A Loans made by such Lender or any Letter of Credit or participation therein, and the result of any of the foregoing shall be to increase the cost to such Lender or Issuing Bank of making or maintaining any Eurocurrency Loan or B/A Loan or increase the cost to any Lender of issuing or maintaining any Letter of Credit or purchasing or maintaining a participation therein or to reduce the amount of any sum received or receivable by such Lender or Issuing Bank hereunder (whether of principal, interest or otherwise), in each case, by an amount deemed by such Lender or Issuing Bank (acting reasonably) to be material, then the applicable Borrower will pay to such Lender or Issuing Bank, as the case may be, upon demand in accordance with paragraph (c) below such additional amount or amounts as will compensate such Lender or Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered. (b) If any Lender or Issuing Bank (acting reasonably) shall have determined that any Change in Law regarding capital adequacy has or would have the effect of reducing the rate of return on such Lender's or Issuing Bank's capital or on the capital of such Lender's or Issuing Bank's holding company, if any, as a consequence of this Agreement or the Loans made or participations in Letters of Credit purchased by such Lender pursuant hereto or the Letters of Credit issued by such Issuing Bank pursuant hereto to a level below that which such Lender or Issuing Bank or such Lender's or Issuing Bank's holding company could have achieved but for such Change in Law (taking into consideration such Lender's or Issuing Bank's policies and the policies of such Lender's or Issuing Bank's holding company with respect to capital adequacy) by an amount deemed by such Lender or Issuing Bank (acting reasonably) to be material, then from time to time in accordance with paragraph (c) below the applicable Borrower shall pay to such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or Issuing Bank or such Lender's or Issuing Bank's holding company for any such reduction suffered. (c) A certificate of a Lender or Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or Issuing Bank or its holding company, as applicable, as specified in paragraph (a) or (b) above shall be delivered to the applicable Borrower and shall be conclusive absent manifest error. The applicable Borrower shall pay such Lender or the Issuing Bank the amount shown as due on any such certificate delivered by it within 10 days after its receipt of the same. 41 (d) Failure or delay on the part of any Lender or Issuing Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of such Lender's or Issuing Bank's right to demand such compensation; provided that the Borrowers shall not be under any obligation to compensate any Lender or Issuing Bank under paragraph (a) or (b) above with respect to increased costs or reductions with respect to any period prior to the date that is 120 days prior to such request if such Lender or Issuing Bank knew or could reasonably have been expected to know of the circumstances giving rise to such increased costs or reductions and of the fact that such circumstances would result in a claim for increased compensation by reason of such increased costs or reductions; provided further that the foregoing limitation shall not apply to any increased costs or reductions arising out of the retroactive application of any Change in Law within such 120-day period. The protection of this Section shall be available to each Lender and Issuing Bank regardless of any possible contention of the invalidity or inapplicability of the Change in Law that shall have occurred or been imposed. SECTION 2.14. CHANGE IN LEGALITY. (a) Notwithstanding any other provision of this Agreement, if any Change in Law shall make it unlawful for any Lender to make or maintain any Eurocurrency Loan or to give effect to its obligations as contemplated hereby with respect to any Eurocurrency Loan, then, by written notice to the Borrowers and to the Administrative Agent: (i) such Lender may declare that Eurocurrency Loans will not thereafter (for the duration of such unlawfulness) be made by such Lender hereunder (or be continued for additional Interest Periods and ABR Loans and U.S. Base Rate Loans will not thereafter (for such duration) be converted into Eurocurrency Loans), whereupon any request for a Eurocurrency Borrowing (or to convert an ABR Borrowing to a Eurocurrency Borrowing or to continue a Eurocurrency Borrowing for an additional Interest Period) shall, as to such Lender only, be deemed a request for an ABR Loan or a U.S. Base Rate Loan (or a request to continue an ABR Loan or a U.S. Base Rate Loan as such or to convert a Eurocurrency Loan into an ABR Loan or a U.S. Base Rate Loan), unless such declaration shall be subsequently withdrawn; and (ii) such Lender may require that all outstanding Eurocurrency Loans made by it be converted to ABR Loans or U.S. Base Rate Loans, as the case may be, in which event all such Eurocurrency Loans shall be automatically converted to ABR Loans or U.S. Base Rate Loans, as the case may be, as of the effective date of such notice as provided in paragraph (b) below. In the event any Lender shall exercise its rights under (i) or (ii) above, all payments and prepayments of principal that would otherwise have been applied to repay the Eurocurrency Loans that would have been made by such Lender or the converted Eurocurrency Loans of such Lender shall instead be applied to repay the ABR Loans or U.S. Base Rate Loans made by such Lender in lieu of, or resulting from the conversion of, such Eurocurrency Loans. 42 (b) For purposes of this Section 2.14, a notice to the U.S. Borrower by any Lender shall be effective as to each Eurocurrency Loan made by such Lender, if lawful, on the last day of the Interest Period then applicable to such Eurocurrency Loan; in all other cases such notice shall be effective on the date of receipt by such Borrower. SECTION 2.15. INDEMNITY. The Borrowers shall severally indemnify each Lender against any loss or expense that such Lender may sustain or incur as a consequence of (a) any event, other than a default by such Lender in the performance of its obligations hereunder, which results in (i) such Lender receiving or being deemed to receive any amount on account of the principal of any Eurocurrency Loan prior to the end of the Interest Period in effect therefor, (ii) the conversion of any Eurocurrency Loan to an ABR Loan or U.S. Base Rate Loans or the conversion of the Interest Period with respect to any Eurocurrency Loan, in each case other than on the last day of the Interest Period in effect therefor, or (iii) any Eurocurrency Loan or B/A Loan to be made by such Lender (including any Eurocurrency Loan or B/A Loan to be made pursuant to a conversion or continuation under Section 2.10 or 2.22, as applicable) not being made after notice of such Loan shall have been given by a Borrower hereunder (any of the events referred to in this clause (a) being called a "Breakage Event") or (b) any default in the making of any payment or prepayment required to be made hereunder. In the case of any Breakage Event, such loss shall include an amount equal to the excess, as reasonably determined by such Lender, of (i) its cost of obtaining funds for the Eurocurrency Loan or B/A Loan that is the subject of such Breakage Event for the period from the date of such Breakage Event to the last day of the Interest Period or Contract Period in effect (or that would have been in effect) for such Loan over (ii) the amount of interest likely to be realized by such Lender in redeploying the funds released or not utilized by reason of such Breakage Event for such period. A certificate of any Lender setting forth any amount or amounts which such Lender is entitled to receive pursuant to this Section 2.15 shall be delivered to the applicable Borrower and shall be conclusive absent manifest error. SECTION 2.16. PRO RATA TREATMENT. (a) Except as required under Section 2.14, each Borrowing, each payment or prepayment of principal of any Borrowing, each payment of interest on the Loans, each payment of the Commitment Fees, each reduction of the Commitments and each conversion of any Borrowing to or continuation of any Borrowing as a Borrowing of any Type shall be allocated pro rata among the Lenders in accordance with their respective Commitments of the applicable Class (or, if such Commitments shall have expired or been terminated, in accordance with the respective principal amounts of their outstanding Loans). (b) Notwithstanding any other provision of this Agreement or the Security Documents, it is the intent of the Secured Parties that each of the Secured Parties shall share in the aggregate proceeds of the Collateral on a pro rata basis as provided in paragraph (a) above. Accordingly, if the proceeds in respect of one class of Collateral (i.e., U.S. Collateral or Canadian Collateral) are insufficient to repay the Obligations intended to be secured by such class of Collateral pursuant to the Security Documents, the Agents, shall, to the extent they deem necessary, allocate and reallocate the proceeds of the Collateral to ensure that each Secured Party receives its pro rata share of the 43 proceeds of all the Collateral. If after giving effect to the allocations described in the preceding sentence any Secured Party shall have received less than its pro rata share of the aggregate proceeds of all the Collateral, each Secured Party that received more than its pro rata share of the aggregate proceeds of all the Collateral agrees to deliver to the Agents, for reallocation to the Secured Parties that received less than their pro rata share of the proceeds of all the Collateral, the excess of the aggregate amount received by such Secured Party over the amount that would have been such Secured Party's pro rata share of the proceeds of all the Collateral. SECTION 2.17. SHARING OF SETOFFS. (a) Each Canadian Lender agrees that if it shall, through the exercise of a right of banker's lien, setoff or counterclaim against a Borrower or any other Loan Party, or pursuant to a secured claim or other security or interest arising from, or in lieu of, such secured claim, received by such Canadian Lender under any applicable Insolvency Law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any Canadian Loan as a result of which the unpaid portion of its Canadian Loans shall be proportionately less than the unpaid portion of the Canadian Loans of any other Canadian Lender, it shall be deemed simultaneously to have purchased from such other Canadian Lender at face value, and shall promptly pay to such other Canadian Lender the purchase price for, a participation in the Canadian Loans of such other Canadian Lender, so that the aggregate unpaid amount of the Canadian Loans and participations in Canadian Loans held by each Canadian Lender shall be in the same proportion to the aggregate unpaid amount of all Canadian Loans then outstanding as the amount of its Canadian Loans prior to such exercise of banker's lien, setoff or counterclaim or other event was to the amount of all Canadian Loans outstanding prior to such exercise of banker's lien, setoff or counterclaim or other event; provided, however, that if any such purchase or purchases or adjustments shall be made pursuant to this Section 2.17(a) and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. (b) Each U.S. Lender agrees that if it shall, through the exercise of a right of banker's lien, setoff or counterclaim against a Borrower or any other Loan Party, or pursuant to a secured claim or other security or interest arising from, or in lieu of, such secured claim, received by such U.S. Lender under any applicable Insolvency Law or otherwise, or by any other means, obtain payment (voluntary or involuntary) in respect of any U.S. Loan as a result of which the unpaid portion of its U.S. Loans shall be proportionately less than the unpaid portion of the U.S. Loans of any other U.S. Lender, it shall be deemed simultaneously to have purchased from such other U.S. Lender at face value, and shall promptly pay to such other U.S. Lender the purchase price for, a participation in the U.S. Loans of such other U.S. Lender, so that the aggregate unpaid amount of the U.S. Loans and participations in U.S. Loans held by each U.S. Lender shall be in the same proportion to the aggregate unpaid amount of all U.S. Loans then outstanding as the amount of its U.S. Loans prior to such exercise of banker's lien, setoff or counterclaim or other event was to the amount of all U.S. Loans outstanding prior to such exercise of banker's lien, setoff or counterclaim or other event; provided, however, that if any such purchase or purchases or adjustments shall be made pursuant to this 44 Section 2.17(b) and the payment giving rise thereto shall thereafter be recovered, such purchase or purchases or adjustments shall be rescinded to the extent of such recovery and the purchase price or prices or adjustment restored without interest. (c) Each Borrower expressly consents to the arrangements set forth in clause (a) and (b) above and agrees that any Lender holding a participation in a Loan to such Borrower deemed to have been so purchased may exercise any and all rights of banker's lien, setoff or counterclaim with respect to any and all moneys owing by such Borrower to such Lender by reason thereof as fully as if such Lender had made a Loan directly to such Borrower in the amount of such participation. SECTION 2.18. PAYMENTS. (a) The Borrowers shall make each payment (including principal of or interest on any Borrowing or any L/C Disbursement or any Fees or other amounts) hereunder and under any other Loan Document not later than 2:00 p.m., Standard Time, on the date when due in immediately available U.S. dollars (or Canadian dollars, in the case of payments relating to Commitments, Loans and Letters of Credit denominated in Canadian dollars), without setoff, defense or counterclaim. Each such payment (other than Issuing Bank Fees, which shall be paid directly to the Applicable Issuing Bank) shall be made to the Administrative Agent at its offices at 1740 Broadway, MAC C7300-034, Denver, Colorado 80209 or in the case of payments by or on behalf of the Canadian Borrower, to the accounts in Toronto, Ontario designated by the Canadian Administrative Agent. The Administrative Agent or the Canadian Administrative Agent, as applicable, shall promptly thereafter cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent, the Canadian Administrative Agent, a specific Issuing Bank, or a specific Lender pursuant to Section 2.05, 2.08, 2.13, 2.14, 2.15, 2.19, or 9.05, but after taking into account payments effected pursuant to Section 9.05(a)) in accordance with each Lender's U.S. Pro Rata Percentage or Canadian Pro Rata Percentage, as applicable, thereof, to the Lenders for the account of their respective applicable lending offices, and like funds relating to the payment of any other amount payable to any Lender or Issuing Bank to such Lender or Issuing Bank for the account of its applicable lending office, in each case to be applied in accordance with the terms of this Agreement. (b) Except as otherwise expressly provided herein, whenever any payment (including principal of or interest on any Borrowing or any Fees or other amounts) hereunder or under any other Loan Document shall become due, or otherwise would occur, on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of interest or Fees, if applicable. SECTION 2.19. TAXES. (a) Any and all payments by or on account of any obligation of the Borrowers or any Loan Party hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if a Borrower or any Loan Party shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that, after making all required deductions 45 (including deductions applicable to additional sums payable under this Section), the Applicable Administrative Agent or such Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower or such Loan Party shall make such deductions and (iii) such Borrower or such Loan Party shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law. (b) In addition, the Borrowers shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. (c) Each Borrower shall indemnify the Applicable Administrative Agent and each Lender, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by such Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of such Borrower or any Loan Party hereunder or under any other Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the applicable Borrower by a Lender, or by the Applicable Administrative Agent on its behalf or on behalf of a Lender, shall be conclusive absent manifest error. (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by a Borrower or any other Loan Party to a Governmental Authority, 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. (e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the applicable Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall, if such payment otherwise would be subject to a withholding Tax, deliver to the applicable Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by a Borrower as will permit such payments to be made without withholding or at a reduced rate. (f) Each Canadian Lender represents that it is a resident of Canada for purposes of the ITA. SECTION 2.20. ASSIGNMENT OF COMMITMENTS UNDER CERTAIN CIRCUMSTANCES; DUTY TO MITIGATE. (a) In the event (i) any Lender or Issuing Bank delivers a certificate requesting compensation pursuant to Section 2.13, (ii) any Lender or Issuing Bank delivers a notice described in Section 2.14, (iii) a Borrower is required to pay any additional amount to any Lender or Issuing Bank or any Governmental Authority on 46 account of any Lender or Issuing Bank pursuant to Section 2.19, (iv) any Lender fails to agree to an extension of the Maturity Date as provided in Section 2.09(d), or (v) any Lender breaches its obligations to fund a Loan under Section 2.02, then the applicable Borrower may, at its sole expense and effort (including with respect to the processing and recordation fee referred to in Section 9.04(b)), upon notice to such Lender or Issuing Bank and the Administrative Agent, require such Lender or Issuing Bank to transfer and assign, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all of its interests, rights and obligations under this Agreement to an assignee that shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (x) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority having jurisdiction, (y) the applicable Borrower shall have received the prior written consent of the Administrative Agent and the Applicable Issuing Bank, which consent shall not unreasonably be withheld or delayed, and (z) the applicable Borrower or such assignee shall have paid to the affected Lender or Issuing Bank in immediately available funds an amount equal to the sum of the principal of and interest accrued to the date of such payment on the outstanding Loans or L/C Disbursements of such Lender or Issuing Bank, respectively, plus all Fees and other amounts accrued for the account of such Lender or Issuing Bank hereunder (including any amounts under Section 2.13 and Section 2.15). (b) If (i) any Lender or Issuing Bank shall request compensation under Section 2.13, (ii) any Lender or Issuing Bank delivers a notice described in Section 2.14 or (iii) a Borrower is required to pay any additional amount to any Lender or Issuing Bank or any Governmental Authority on account of any Lender or Issuing Bank, pursuant to Section 2.19, then such Lender or Issuing Bank shall use reasonable efforts (which shall not require such Lender or Issuing Bank to incur an unreimbursed loss or unreimbursed cost or expense or otherwise take any action inconsistent with its internal policies or legal or regulatory restrictions or suffer any disadvantage or burden deemed by it to be significant) (x) to file any certificate or document reasonably requested in writing by such Borrower or (y) to assign its rights and delegate and transfer its obligations hereunder to another of its offices, branches or affiliates, if such filing or assignment would reduce its claims for compensation under Section 2.13 or enable it to withdraw its notice pursuant to Section 2.14 or would reduce amounts payable pursuant to Section 2.19, as the case may be, in the future. Each Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender or Issuing Bank in connection with any such filing or assignment, delegation and transfer. SECTION 2.21. LETTERS OF CREDIT. (a) General. Each Borrower may request the issuance of a Letter of Credit for its own account or for the account of any of its wholly owned Subsidiaries (in which case such Borrower and such wholly owned Subsidiary shall be co-applicants with respect to such Letter of Credit), in a form reasonably acceptable to the Administrative Agent and the Applicable Issuing Bank, at any time and from time to time while the Commitments remain in effect, but no later than five Business Days prior to the Maturity Date. This Section shall not be construed to impose an obligation upon an Issuing Bank to issue any Letter of Credit that is inconsistent with the terms and conditions of this Agreement. 47 (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. In order to request the issuance of a Letter of Credit (or to amend, renew or extend an existing Letter of Credit), the applicable Borrower shall hand deliver or fax to the Applicable Issuing Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, the date of issuance, amendment, renewal or extension, the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) below), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare such Letter of Credit. A U.S. Letter of Credit shall be issued, amended, renewed or extended only if, and upon issuance, amendment, renewal or extension of each Letter of Credit the U.S. Borrower shall be deemed to represent and warrant that, after giving effect to such issuance, amendment, renewal or extension (i) the U.S. L/C Exposure shall not exceed U.S.$25,000,000 and (ii) the aggregate U.S. Credit Exposure shall not exceed the Total U.S. Commitment. A Canadian Letter of Credit shall be issued, amended, renewed or extended only if, and upon issuance, amendment, renewal or extension of each Canadian Letter of Credit, the Canadian Borrower shall be deemed to represent and warrant that after giving effect to such issuance, amendment, renewal or extension (i) the Canadian L/C Exposure shall not exceed the Canadian Dollar Equivalent of U.S.$7,500,000 and (ii) the aggregate Canadian Credit Exposure shall not exceed the Total Canadian Commitment. (c) Expiration Date. Each Letter of Credit shall expire at the close of business on the earlier of the date one year after the date of the issuance of such Letter of Credit and the date that is five Business Days prior to the Maturity Date, unless such Letter of Credit expires by its terms on an earlier date; provided that a Letter of Credit may provide for automatic extension of any expiration date for additional periods of up to one year (but not past the Maturity Date), subject to a right on the part of the Issuing Bank to prevent any such automatic extension from occurring by giving reasonable notice to the beneficiary during a period satisfactory to the Administrative Agent. (d) Participations. By the issuance of a Letter of Credit and without any further action on the part of an Issuing Bank or the Lenders, the Applicable Issuing Bank hereby grants to each U.S. Lender or Canadian Lender, as the case may be, and each such Lender hereby acquires from the Applicable Issuing Bank, a participation in such Letter of Credit equal to such Lender's U.S. Pro Rata Percentage or Canadian Pro Rata Percentage, as applicable, of the aggregate amount available to be drawn under such Letter of Credit, effective upon the issuance of such Letter of Credit (or, in the case of the Rolled Letters of Credit, effective upon the Closing Date). In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Applicable Administrative Agent, for the account of the Applicable Issuing Bank, such Lender's U.S. Pro Rata Percentage or Canadian Pro Rata Percentage, as applicable, of each L/C Disbursement made by such Issuing Bank and not reimbursed by the applicable Borrower (or, if applicable, another party pursuant to its obligations under any other Loan Document) forthwith on the date due as provided in Section 2.02(f), in the same currency in which such L/C Disbursement is denominated. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters 48 of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or an Event of Default, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. (e) Reimbursement. If an Issuing Bank shall make any L/C Disbursement in respect of a Letter of Credit, the applicable Borrower shall pay to the Applicable Administrative Agent an amount equal to such L/C Disbursement not later than two hours after such Borrower shall have received notice from such Issuing Bank that payment of such draft will be made, or, if such Borrower shall have received such notice later than 11:00 a.m., Standard Time, on any Business Day, not later than 11:00 a.m., Standard Time, on the immediately following Business Day. (f) Obligations Absolute. Each Borrower's obligations to reimburse L/C Disbursements as provided in paragraph (e) above shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, under any and all circumstances whatsoever, and irrespective of: (i) any lack of validity or enforceability of any Letter of Credit or any Loan Document, or any term or provision therein; (ii) any amendment or waiver of or any consent to departure from all or any of the provisions of any Letter of Credit or any Loan Document; (iii) the existence of any claim, setoff, defense or other right that such Borrower, any other party guaranteeing, or otherwise obligated with, such Borrower, any subsidiary or other Affiliate thereof or any other person may at any time have against the beneficiary under any Letter of Credit, the Applicable Issuing Bank, the Administrative Agent or any Lender or any other person, whether in connection with this Agreement, any other Loan Document or any other related or unrelated agreement or transaction; (iv) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (v) payment by the Applicable Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not strictly comply with the terms of such Letter of Credit; and (vi) any other act or omission to act or delay of any kind of the Applicable Issuing Bank, the Lenders, the Administrative Agent or any other person or any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of such Borrower's obligations hereunder. Without limiting the generality of the foregoing, it is expressly understood and agreed that the absolute and unconditional obligation of each Borrower hereunder to 49 reimburse L/C Disbursements will not be excused by the gross negligence or willful misconduct of the Applicable Issuing Bank. However, the foregoing shall not be construed to excuse the Applicable Issuing Bank from liability to a Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrowers to the extent permitted by applicable law) suffered by such Borrower that are caused by such Issuing Bank's failure to comply with its duties as an issuing bank under applicable law or gross negligence or willful misconduct in determining whether drafts and other documents presented under a Letter of Credit strictly comply with the terms thereof; it is understood that the Applicable Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary and, in making any payment under any Letter of Credit (i) such Issuing Bank's exclusive reliance on the documents presented to it under such Letter of Credit as to any and all matters set forth therein, including reliance on the amount of any draft presented under such Letter of Credit, whether or not the amount due to the beneficiary thereunder equals the amount of such draft and whether or not any document presented pursuant to such Letter of Credit proves to be insufficient in any respect, if such document on its face appears to be in order, and whether or not any other statement or any other document presented pursuant to such Letter of Credit proves to be forged or invalid or any statement therein proves to be inaccurate or untrue in any respect whatsoever and (ii) any noncompliance in any immaterial respect of the documents presented under such Letter of Credit with the terms thereof shall, in each case, be deemed not to constitute willful misconduct or gross negligence of the Applicable Issuing Bank. (g) Disbursement Procedures. The Applicable Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Applicable Issuing Bank shall as promptly as possible give telephonic notification, confirmed by fax, to the Administrative Agent and the applicable Borrower of such demand for payment and whether the Applicable Issuing Bank has made or will make an L/C Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the applicable Borrower of its obligation to reimburse the Applicable Issuing Bank and the Lenders with respect to any such L/C Disbursement. The Administrative Agent shall promptly give each Lender notice thereof. (h) Interim Interest. If an Issuing Bank shall make any L/C Disbursement in respect of a Letter of Credit, then, unless the applicable Borrower shall reimburse such L/C Disbursement in full on such date, the unpaid amount thereof shall bear interest for the account of the Applicable Issuing Bank, for each day from and including the date of such L/C Disbursement, to but excluding the earlier of the date of payment by such Borrower or the date on which interest shall commence to accrue thereon as provided in Section 2.02(f), at the rate per annum that would apply to such amount if such amount were an ABR Loan or a Canadian Prime Rate Loan, as the case may be. (i) Resignation or Removal of an Issuing Bank. An Issuing Bank may resign at any time by giving 30 days' prior written notice to the Administrative Agent, the Lenders and the Borrowers, and may be removed at any time by the U.S. Borrower by notice to 50 such Issuing Bank, the Administrative Agent and the Lenders. Subject to the next succeeding paragraph, upon the acceptance of any appointment as an Issuing Bank hereunder by a Lender that shall agree to serve as successor Issuing Bank, such successor shall succeed to and become vested with all the interests, rights and obligations of the retiring Issuing Bank and the retiring Issuing Bank shall be discharged from its obligations to issue additional Letters of Credit hereunder. At the time such removal or resignation shall become effective, the applicable Borrower shall pay all accrued and unpaid fees pursuant to Section 2.05(c)(ii). The acceptance of any appointment as an Issuing Bank hereunder by a successor Lender shall be evidenced by an agreement entered into by such successor, in a form satisfactory to the Borrowers and the Administrative Agent, and, from and after the effective date of such agreement, (i) such successor Lender shall have all the rights and obligations of the previous Issuing Bank under this Agreement and the other Loan Documents and (ii) references herein and in the other Loan Documents to the term "Issuing Bank" shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the resignation or removal of an Issuing Bank hereunder, the retiring Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation or removal, but shall not be required to issue additional Letters of Credit. (j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing, other than an event with respect to a Borrower described in paragraph (g) or (h) of Article VII, and a Borrower shall receive notice from the Administrative Agent or the Required U.S. Lenders or the Required Canadian Lenders requesting that it deposit cash collateral and specifying the amount to be deposited, or (ii) an Event of Default shall occur and be continuing with respect to either Borrower described in paragraph (g) or (h) of Article VII, then such Borrower shall, on the Business Day it receives the notice referenced in clause (i) above or immediately upon the occurrence of the Event of Default referenced in clause (ii) above, deposit in an account with the U.S. Collateral Agent or the Canadian Collateral Agent, as the case may be, for the benefit of the U.S. Lenders or Canadian Lenders, as the case may be, an amount in cash equal to the U.S. L/C Exposure or the Canadian L/C Exposure, respectively, as of such date. Such deposit shall be held by the U.S. Collateral Agent or the Canadian Collateral Agent, as the case may be, as collateral for the payment and performance of the Obligations. Such Collateral Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits in Permitted Investments, which investments shall be made at the option and sole discretion of such Collateral Agent, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall (i) automatically be applied by the Applicable Administrative Agent to reimburse the Applicable Issuing Bank for L/C Disbursements for which it has not been reimbursed, (ii) be held for the satisfaction of the reimbursement obligations of the applicable Borrower for the U.S. L/C Exposure or the Canadian L/C Exposure, as applicable, at such time and (iii) if the maturity of the Loans has been accelerated, be applied to satisfy the Obligations. If a Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not 51 applied as aforesaid) shall be returned to such Borrower within three Business Days after all Events of Default have been cured or waived. (k) Additional Issuing Banks. A Borrower may, at any time and from time to time with the consent of the Administrative Agent (which consent shall not be unreasonably withheld or delayed) and such Lender, designate one or more additional Lenders to act as an issuing bank under the terms of this Agreement; provided, however, that there shall not be more than five Issuing Banks at any time. Any Lender designated as an issuing bank pursuant to this paragraph (k) shall be deemed (in addition to being a Lender) to be the Issuing Bank with respect to Letters of Credit issued or to be issued by such Lender, and all references herein and in the other Loan Documents to the term "Issuing Bank" shall, with respect to such Letters of Credit, be deemed to refer to such Lender in its capacity as Issuing Bank. SECTION 2.22. BANKERS' ACCEPTANCES. (a) Subject to the terms and conditions of this Agreement, the Canadian Borrower may request a Borrowing denominated in Canadian dollars by presenting drafts for acceptance and, if applicable, purchase as B/As by the Canadian Lenders. (b) No Contract Period with respect to a B/A to be accepted and, if applicable, purchased as a Loan shall extend beyond the Maturity Date. All B/A Loans shall be denominated in Canadian dollars. (c) To facilitate availment of the B/A Loans, the Canadian Borrower hereby appoints each Canadian Lender as its attorney to sign and endorse on its behalf, in handwriting or by facsimile or mechanical signature as and when deemed necessary by such Canadian Lender, blank forms of B/As in the form requested by such Canadian Lender. The Canadian Borrower recognizes and agrees that all B/As signed and/or endorsed on its behalf by a Canadian 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 Canadian Lender is hereby authorized to issue such B/As endorsed in blank in such face amounts as may be determined by such Canadian Lender; provided that the aggregate amount thereof is equal to the aggregate amount of B/As required to be accepted and purchased by such Canadian Lender. No Canadian Lender shall be liable for any damage, loss or other claim arising by reason of any loss or improper use of any such instrument except the gross negligence or willful misconduct of such Canadian Lender or its officers, employees, agents or representatives. Each Canadian Lender shall maintain a record with respect to B/As (i) voided by it for any reason, (ii) accepted and purchased by it hereunder and (iii) canceled at their respective maturities. Each Canadian Lender further agrees to retain such records in the manner and for the statutory periods provided in the various provincial or federal statutes and regulations which apply to such Canadian Lender. On request by or on behalf of the Canadian Borrower, a Canadian Lender shall cancel all forms of B/A which have been pre-signed or pre-endorsed on behalf of the Canadian Borrower and which are held by such Canadian Lender and are not required to be issued in accordance with the Canadian Borrower's irrevocable notice. At the discretion of a Lender, Bankers' Acceptances to be accepted by such Lender may be issued in the form of "Depository Bills" within the 52 meaning of the Depository Bills and Notes Act (Canada) and deposited with the Canadian Depository for Securities Limited ("CDS") and may be made payable to "CDS & Co." or in such other name as may be acceptable to CDS and thereafter dealt with in accordance with the rules and procedures of CDS, consistent with the terms of this Agreement. All Depository Bills so issued shall be governed by the provisions of this Section 2.22. (d) Drafts of the Canadian Borrower to be accepted as B/As hereunder shall be signed as set forth in this Section 2.22. Notwithstanding that any person whose signature appears on any B/A may no longer be an authorized signatory for any of the Canadian Lenders or the Canadian Borrower at the date of issuance of a B/A, 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 B/A so signed shall be binding on the Canadian Borrower. (e) Promptly following receipt of a notice of borrowing, continuation or conversion of B/As, the Canadian Administrative Agent shall so advise the Canadian Lenders and shall advise each Canadian Lender of the aggregate face amount of the B/As to be accepted by it and the applicable Contract Period (which shall be identical for all Canadian Lenders). The aggregate face amount of the B/As to be accepted by a Canadian Lender shall be in an integral multiple of C$100,000 and such face amount shall be in each Canadian Lender's pro rata portion of such Canadian Borrowing; provided, that the Canadian Administrative Agent may, in its sole discretion, increase or reduce any Canadian Lender's portion of such B/A to the nearest C$100,000. (f) The Canadian Borrower may specify in a notice of borrowing or conversion or continuation pursuant to Section 2.03 or Section 2.10, respectively, that it desires that any B/As requested by such notice be purchased by the Canadian Lenders, in which case the Canadian Lenders shall purchase, or arrange the purchase of, each B/A from the Canadian Borrower at the Discount Rate for such Canadian Lender applicable to such B/A accepted by it and provide to the Canadian Administrative Agent the Discount Proceeds for the account of the Canadian Borrower. The Acceptance Fee payable by the Canadian Borrower to a Canadian Lender under Section 2.06 in respect of each B/A accepted by such Canadian Lender shall be set off against the Discount Proceeds payable by such Canadian Lender under this Section 2.22. (g) Each Canadian Lender may at any time and from time to time hold, sell, rediscount or otherwise dispose of any or all B/As accepted and purchased by it. (h) If a Canadian Lender notifies the Canadian Administrative Agent in writing that it is unable to accept Bankers' Acceptances, such Canadian Lender will, instead of accepting and, if applicable, purchasing Bankers' Acceptances, make an advance (a "B/A Equivalent Loan") to the Canadian Borrower in the amount and for the same term as the draft that such Canadian Lender would otherwise have been required to accept and purchase hereunder. Each such Canadian Lender will provide to the Canadian Administrative Agent the Discount Proceeds of such B/A Equivalent Loan for the account of the Canadian Borrower. Each such B/A Equivalent Loan will bear interest at 53 the same rate that would result if such Lender had accepted (and been paid an Acceptance Fee) and purchased (on a discounted basis at the Discount Rate) a Bankers' Acceptance for the relevant Contract Period (it being the intention of the parties that each such B/A Equivalent Loan shall have the same economic consequences for the Lenders and the Canadian Borrower as the Bankers' Acceptance which such B/A Equivalent Loan replaces). All such interest shall be paid in advance on the date such B/A Equivalent Loan is made, and will be deducted from the principal amount of such B/A Equivalent Loan in the same manner in which the Discount Proceeds of a Bankers' Acceptance would be deducted from the face amount of the Bankers' Acceptance. (i) The Canadian Borrower waives presentment for payment and any other defense to payment of any amounts due to a Canadian Lender in respect of a B/A accepted and purchased by it pursuant to this Agreement which might exist solely by reason of such B/A being held, at the maturity thereof, by such Canadian Lender in its own right and the Canadian Borrower agrees not to claim any days of grace if such Canadian Lender as holder sues the Canadian Borrower on the B/A for payment of the amount payable by the Canadian Borrower thereunder. On the last day of the Contract Period of a B/A, or such earlier date as may be required or permitted pursuant to the provisions of this Agreement, the Canadian Borrower shall pay the Canadian Lender that has accepted and purchased such B/A the full face amount of such B/A and after such payment, the Canadian Borrower shall have no further liability in respect of such B/A and such Canadian Lender shall be entitled to all benefits of, and be responsible for all payments due to third parties under, such B/A. (j) Except as required by any Canadian Lender upon the occurrence of an Event of Default, no B/A Loan may be repaid by the Canadian Borrower prior to the expiry date of the Contract Period applicable to such B/A Loan; provided, however, that any B/A Loan may be defeased as provided in the proviso to Section 2.11(a). SECTION 2.23. INCREASE IN COMMITMENTS. (a) The U.S. Borrower may, by written notice to the Administrative Agents from time to time after the Closing Date, request that the Total Commitment be increased by an amount not to exceed the Incremental Commitment Amount at such time by delivering a request to the Administrative Agent, who shall deliver a copy thereof to each Lender. Such notice shall set forth (a) the amount of the requested increase in the Total Commitment (which shall be in minimum increments of U.S.$1,000,000 and a minimum amount of U.S.$5,000,000 or equal to the remaining Incremental Commitment Amount), (b) the amount of the requested increase in the Total U.S. Commitment, the Total Canadian Commitment or both and (c) the date on which such increase is requested to become effective (which shall not be less than 10 Business Days nor more than 60 days after the date of such notice and which, in any event, must be on or prior to the Maturity Date), and shall offer each Lender the opportunity to increase its U.S. Commitment or its Canadian Commitment, as applicable and as the case may be, by its U.S. Pro Rata Percentage or its Canadian Pro Rata Percentage, as applicable and as the case may be, of the proposed increase amount. Each Lender shall, by notice to the Borrowers and the Administrative Agents given not more than 10 days after the date of the Administrative Agent's notice, either agree to increase its Commitment by all or a portion of the offered amount (each 54 Lender so agreeing being an "Increasing Lender") or decline to increase its Commitment (and any Lender that does not deliver such a notice within such period of 10 days shall be deemed to have declined to increase its Commitment) (each Lender so declining or being deemed to have declined being a "Non-Increasing Lender"). In the event that, on the 10th day after the Administrative Agent shall have delivered a notice pursuant to the second sentence of this paragraph, the Lenders shall have declined any increase or agreed pursuant to the preceding sentence to increase their Commitment by an aggregate amount less than the increase in the Total Commitment requested by the U.S. Borrower, the U.S. Borrower may arrange for one or more banks or other entities (any such bank or other entity referred to in this clause (a) being called an "Augmenting Lender" and, together with the Increasing Lenders, the "Incremental Lenders"), to extend the Commitment in an aggregate amount equal to the unsubscribed amount; provided that each Augmenting Lender shall be subject to the approval of the Administrative Agents and the Issuing Banks (which approvals shall not be unreasonably withheld or delayed). Any increase in the Total Commitment may be made in an amount which is less than the increase requested by the U.S. Borrower if the U.S. Borrower is unable to arrange for, or chooses not to arrange for, Augmenting Lenders. (b) The Borrowers and each Incremental Lender shall execute and deliver to the Administrative Agent an Incremental Assumption Agreement and such other documentation as the Administrative Agent shall reasonably specify to evidence the Incremental Commitment of such Incremental Lender or its status as a Lender hereunder. The Administrative Agent shall promptly notify each Lender as to the effectiveness of each Incremental Assumption Agreement. Each of the parties hereto hereby agrees that, upon the effectiveness of any Incremental Assumption Agreement, this Agreement shall be deemed amended to the extent (but only to the extent) necessary to reflect the existence and terms of the Incremental Commitment evidenced thereby. (c) Each of the parties hereto hereby agrees that the Administrative Agents may take any and all actions as may be reasonably necessary to ensure that, after giving effect to any increase in the Total Commitment pursuant to this Section 2.23, the outstanding U.S. Loans (if any) are held by the U.S. Lenders in accordance with their new U.S. Pro Rata Percentages and the outstanding Canadian Loans (if any) are held by the Canadian Lenders in accordance with their new Canadian Pro Rata Percentages. This may be accomplished at the discretion of the Administrative Agents (i) by requiring the outstanding Loans to be prepaid with the proceeds of a new Borrowing, (ii) by causing Non-Increasing Lenders to assign portions of their outstanding Loans to Incremental Lenders, (iii) by permitting the Borrowings outstanding at the time of any increase in the Total Commitment pursuant to this Section 2.23 to remain outstanding until the last days of the respective Interest Periods therefor, even though the Lenders would hold such Borrowings other than in accordance with their new Pro Rata Percentages, or (iv) by any combination of the foregoing. Any prepayment or assignment described in this paragraph (c) shall be subject to indemnification by the Borrowers pursuant to Section 2.15, but otherwise without premium or penalty. (d) Notwithstanding the foregoing, no increase in the Total Commitment (or in the Commitment of any Lender) or addition of a new Lender shall become effective 55 under this Section 2.23 unless, (i) on the date of such increase, the conditions set forth in paragraphs (b), (c) and (d) of Section 4.01 shall be satisfied and the Administrative Agent shall have received a certificate to that effect dated such date and executed by a Financial Officer of the U.S. Borrower and (ii) the Administrative Agent shall have received (with sufficient copies for each of the Lenders) legal opinions, board resolutions and an officer's certificate consistent with those delivered on the Closing Date under clauses (a)(i) and (c)(ii)(B) of Section 4.02.

SUBSIDIARIES AND SPECIAL PURPOSES BUSINESS ENTITIES.

SECTION 3.09. LITIGATION; COMPLIANCE WITH LAWS. (a) Except as set forth on Schedule 3.09, there are not any actions, suits or proceedings at law or in equity or by or before any Governmental Authority now pending or, to the knowledge of either Borrower, threatened against either Borrower or any Subsidiary or any business, property or rights of any such person (i) that involve any Loan Document or (ii) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect.

Except as disclosed in Schedule 3.16(a), the present value of all benefit liabilities under each Plan (based on those assumptions used for purposes of Financial Accounting Standards No. 87) did not, as of the last annual valuation preceding the Closing Date, exceed the fair market value of the assets of such Plan. 59 (b) Schedule 3.16(b) sets forth all Canadian Benefit Plans (other than, for greater certainty, universal plans created by and to which the Canadian Borrower is obligated to contribute by statute) and Canadian Pension Plans as of the date of this Agreement.

All contributions or premiums required to be made or paid by the Canadian Borrower and each of its subsidiaries to the Canadian Pension Plans or the Canadian Benefit Plans have been made on a timely basis in accordance with the terms of such plans and all applicable laws. There have been no improper withdrawals or applications of the assets of the Canadian Pension Plans or the Canadian Benefit Plans. Except as disclosed in Schedule 3.16(b), each of the Canadian Pension Plans and the Canadian Benefit Plans is fully funded on a solvency basis and going concern basis (using actuarial methods and assumptions which are consistent with the valuations last filed with the applicable Governmental Authorities and which are consistent with Canadian GAAP).

(a) Each Pledge Agreement is effective to create in favor of the Applicable Collateral Agent, for the ratable benefit of the Secured Parties referred to therein, a legal, valid and enforceable security interest in the Collateral 60 (as defined in such Pledge Agreement) and, when such Collateral (to the extent such Collateral constitutes an instrument under the applicable Uniform Commercial Code or Personal Property Security Act) is delivered to such Collateral Agent, such Pledge Agreement shall constitute a fully perfected first priority Lien on, and security interest in, all right, title and interest of the pledgors thereunder in such Collateral, in each case prior and superior in right to any other person. (b) Each of the Security Agreements is effective to create in favor of the Applicable Collateral Agent, for the ratable benefit of the Secured Parties referred to therein, a legal, valid and enforceable security interest in the Collateral (as defined in such Security Agreement) and, when financing statements in appropriate form are filed in the offices specified on Schedule 6 to the Perfection Certificate, such Security Agreement shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the grantors thereunder in such portion of the Collateral in which a security interest may be perfected by the filing of a financing statement under the applicable Uniform Commercial Code or Personal Property Security Act (other than the Intellectual Property, as defined in the U.S. Security Agreement), in each case prior and superior in right to any other person, other than with respect to Liens expressly permitted by Section 6.02. (c) When the U.S. Security Agreement is filed in the United States Patent and Trademark Office and the United States Copyright Office, and the filings referred to in paragraph (b) above shall have been made, the U.S. Security Agreement and such filings shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the grantors thereunder in the Intellectual Property (as defined in the U.S. Security Agreement) as of the Closing Date, in each case prior and superior in right to any other person (it being understood that subsequent recordings in the United States Patent and Trademark Office and the United States Copyright Office may be necessary to perfect a lien on registered trademarks, trademark applications and copyrights acquired by the grantors after the date hereof). (d) Each Mortgage is effective to create for the ratable benefit of the Secured Parties referred to therein a legal, valid and enforceable security interest in all Collateral or Charged Property (as defined in such Mortgage) and, when appropriate filings or registrations are made in the offices specified on Schedule 3.19, such Mortgage shall constitute a fully perfected Lien on all right, title and interest of the applicable Loan Party thereunder in the applicable Mortgaged Property as of the Closing Date, prior and superior in right to any other person, other than with respect to Liens expressly permitted by Section 6.02. SECTION 3.20. LOCATION OF REAL AND IMMOVABLE PROPERTY AND LEASED PREMISES. (a) Schedule 3.20(a) lists completely and correctly as of the Closing Date all real and immovable property which, individually, have a fair market value in excess of U.S.$250,000 and which is owned in fee by the Borrowers and the Subsidiaries and the addresses thereof. 61 (b) Schedule 3.20(b) lists completely and correctly as of the Closing Date all locations that are not fee owned where inventory or other assets of the Borrowers and the Subsidiaries valued in excess of $250,000 are held. SECTION 3.21. LABOR MATTERS. As of the Closing Date, there are no strikes, lockouts or slowdowns against either Borrower or any Subsidiary pending or, to the knowledge of either Borrower, threatened. The hours worked by and payments made to employees of the Borrowers and the Subsidiaries have not been in violation of the Fair Labor Standards Act or any other applicable federal, state, provincial, local or foreign law dealing with such matters, except where such violation, either individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. All payments due from either Borrower or any Subsidiary, or for which any claim may be made against either Borrower or any Subsidiary, on account of wages and employee health and welfare insurance and other benefits, have been paid or accrued as a liability on the books of such Borrower or such Subsidiary, except where the failure to do the same, either individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. SECTION 3.22. SOLVENCY. Immediately following the making of each Loan and the giving of each of the Guarantee Agreements and after giving effect to the application of the proceeds of each Loan, (a) the fair value of the assets of each Loan Party will exceed its debts and liabilities, subordinated, contingent or otherwise; (b) the present fair saleable value of the property of each Loan Party will be greater than the amount that will be required to pay the probable liability of its debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (c) each Loan Party will be able to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (d) each Loan Party will not have unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted following the Closing Date. SECTION 3.23. TAX SHELTER REGULATIONS. The Borrowers do not intend to treat the Loans and/or Letters of Credit and related transactions as being a "reportable transaction" (within the meaning of Treasury Regulation Section 1.6011-4). In the event either Borrower determines to take any action inconsistent with such intention, it will promptly notify the Administrative Agent thereof. If either Borrower so notifies Administrative Agent, such Borrower acknowledges that one or more of the Lenders may treat its Loans, U.S. L/C Exposure and Canadian L/C Exposure as part of a transaction that is subject to Treasury Regulation Section 301.6112-1. 62 ARTICLE IV Conditions of Lending The obligations of the Lenders to make Loans and of the Issuing Banks to issue Letters of Credit hereunder are subject to the satisfaction of the following conditions: SECTION 4.01. ALL CREDIT EVENTS. On the date of each Borrowing, and on the date of each issuance, amendment, extension or renewal of a Letter of Credit (each such event being called a "Credit Event"): (a) The Applicable Administrative Agent shall have received a notice of such Borrowing as required by Section 2.03 (or such notice shall have been deemed given in accordance with Section 2.03) or, in the case of the issuance, amendment, extension or renewal of a Letter of Credit, the Applicable Issuing Bank and the Applicable Administrative Agent shall have received a notice requesting the issuance, amendment, extension or renewal of such Letter of Credit as required by Section 2.21(b).

Without limiting the generality of the foregoing, the Agents are hereby expressly authorized to execute any and all documents (including releases) with respect to the Collateral and the rights of the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the Security Documents. Each bank serving as an Administrative Agent and/or Collateral Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrowers or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder. No Agent shall have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) no Agent shall be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) no Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that such Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.08), and (c) except as expressly set forth in the Loan Documents, no Agent shall have any duty to disclose, nor shall it be liable for the failure to disclose, any information relating to a Borrower or any of the Subsidiaries that is communicated to or obtained by the bank serving as an Administrative Agent and/or Collateral Agent or any of its Affiliates in any capacity. No Agent shall be liable for any action taken or not taken by it with the consent or at the 84 request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.08) or in the absence of its own gross negligence or willful misconduct. No Agent shall be deemed to have knowledge of any Default unless and until written notice thereof is given to such Agent by a Borrower or a Lender, and no Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered thereunder or in connection therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to such Agent. Each 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 believed by it to be genuine and to have been signed or sent by the proper person. Each Agent may also 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. Each 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. Each Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by it. Each Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of each Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Agent. Subject to the appointment and acceptance of a successor Agent as provided below, any Agent may resign at any time by notifying the Lenders, the Issuing Banks and the Borrowers. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrowers if no Event of Default exists, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring Agent may, on behalf of the Lenders and the Issuing Banks, appoint a successor Agent. Upon the acceptance of its appointment as Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrowers to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrowers and such successor. After an Agent's resignation hereunder, the provisions of this Article and Section 9.05 shall continue in effect for the benefit of such retiring Agent, its sub-agents and their respective Related 85 Parties in respect of any actions taken or omitted to be taken by any of them while acting as Agent. Each Lender acknowledges that it has, independently and without reliance upon the Agents or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Agents or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement or any other Loan Document, any related agreement or any document furnished hereunder or thereunder.

(b) Each Lender may assign to one or more assignees all or a portion of its interests, rights and obligations under this Agreement (including all or a portion of its Commitments and the Loans at the time owing to it); provided, however, that (i) except in the case of an assignment to a Lender or an Affiliate of such Lender, (x) the U.S. Borrower, the Applicable Administrative Agent and the Applicable Issuing Bank must give their prior written consent to such assignment (which consent shall not be unreasonably withheld or delayed); provided, however, that the consent of the U.S. Borrower shall not be required to any such assignment during the continuance of 87 any Event of Default, and (y) the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Applicable Administrative Agent) shall not be less than U.S.$5,000,000 (or, if less, the entire remaining amount of such Lender's Commitment) or such lesser amount as the U.S. Borrower and the Applicable Administrative Agent may from time to time agree (such agreement to be conclusively evidenced by the execution of the related Assignment and Acceptance by all the parties thereto), (ii) the parties to each such assignment shall execute and deliver to the Applicable Administrative Agent an Assignment and Acceptance, together (except in the case of any assignment to an Affiliate) with a processing and recordation fee of U.S.$3,500 or C$5,000, as applicable, and (iii) the assignee, if it shall not be a Lender, shall deliver to the Applicable Administrative Agent an Administrative Questionnaire. Upon acceptance and recording pursuant to paragraph (e) of this Section 9.04, from and after the effective date specified in each Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement and (B) the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (other than under Section 9.16 with respect to Information (as defined in Section 9.16) previously delivered to it) and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.13, 2.15, 2.19 and 9.05 as well as to any Fees accrued for its account and not yet paid. (c) By executing and delivering an Assignment and Acceptance, the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (i) such assigning Lender warrants that it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim and that its Commitment, and the outstanding balances of its Loans, in each case without giving effect to assignments thereof which have not become effective, are as set forth in such Assignment and Acceptance; (ii) except as set forth in (i) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto, or the financial condition of either Borrower or any Subsidiary or the performance or observance by either Borrower or any Subsidiary of any of its obligations under this Agreement, any other Loan Document or any other instrument or document furnished pursuant hereto; (iii) such assignee represents and warrants that it is legally authorized to enter into such Assignment and Acceptance and that, if the assigning Lender is a Canadian Lender, then such assignee is a resident of Canada for the purposes of the ITA; (iv) such assignee confirms that it has received a copy of this Agreement, together with copies of the most recent financial statements referred to in Section 3.05 or delivered pursuant to Section 5.04 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment 88 and Acceptance; (v) such assignee will independently and without reliance upon the Agents, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (vi) such assignee appoints and authorizes the Agents to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Agents by the terms hereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Agreement are required to be performed by it as a Lender. (d) The Applicable Administrative Agent, acting for this purpose as an agent of the Applicable Borrower shall maintain a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The Administrative Agent shall maintain its Register at its offices in Houston, Texas or in Denver, Colorado. The Canadian Administrative Agent shall maintain its Register at one of its offices in The City of Toronto. The entries in the Registers shall be conclusive and the Borrowers, the Administrative Agents, the Issuing Banks, the Collateral Agents and the Lenders may treat each person whose name is recorded in the Registers pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Registers shall be available for inspection by the Borrowers, the Issuing Banks, the Collateral Agents and any Lender, at any reasonable time and from time to time upon reasonable prior notice. (e) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, an Administrative Questionnaire completed in respect of the assignee (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) above, if such assignee is a Foreign Lender with respect to the U.S. Borrower, the documentation referred to in Section 2.19(e), and, if required, the written consent of the U.S. Borrower, the Applicable Issuing Bank and the Applicable Administrative Agent to such assignment, the Applicable Administrative Agent shall (i) accept such Assignment and Acceptance, (ii) record the information contained therein in its Register and (iii) give prompt notice thereof to the Lenders and the Issuing Banks. No assignment shall be effective unless it has been recorded in a Register as provided in this paragraph (e). (f) Each Lender may without the consent of the Borrowers, the Issuing Banks or the Administrative Agents sell participations to one or more banks or other entities in all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided, however, that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participating banks or other entities shall be entitled to the benefit of the cost protection provisions contained in Sections 2.13, 2.15 and 2.19 to the same extent as if they were Lenders (but, with respect to any particular participant, to no greater extent than the Lender that sold the participation to such participant) and (iv) the Borrowers, the 89 Agents, the Issuing Banks and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrowers relating to the Loans or L/C Disbursements and to approve any amendment, modification or waiver of any provision of this Agreement (other than amendments, modifications or waivers decreasing any Fees payable hereunder or the amount of principal of or the rate at which interest is payable on the Loans, extending any scheduled principal payment date or date fixed for the payment of interest on the Loans, increasing or extending the Commitments or releasing any Guarantor or any substantial part of the Collateral, except as expressly permitted hereunder). (g) Any Lender or participant may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 9.04, disclose to the assignee or participant or proposed assignee or participant any information relating to the Borrowers furnished to such Lender by or on behalf of the Borrowers; provided that, prior to any such disclosure of information designated by the Borrowers as confidential, each such assignee or participant or proposed assignee or participant shall execute an agreement whereby such assignee or participant shall agree (subject to customary exceptions) to preserve the confidentiality of such confidential information on terms no less restrictive than those applicable to the Lenders pursuant to Section 9.16. (h) Any Lender may at any time assign all or any portion of its rights under this Agreement to secure extensions of credit to such Lender or in support of obligations owed by such Lender; provided that no such assignment shall release a Lender from any of its obligations hereunder or substitute any such assignee for such Lender as a party hereto. (i) Notwithstanding anything to the contrary contained herein, any Lender (a "Granting Lender") may grant to a special purpose funding vehicle (an "SPC"), identified as such in writing from time to time by the Granting Lender to the Applicable Administrative Agent and the U.S. Borrower or the Canadian Borrower, as applicable, the option to provide to either Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to such Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof, (iii) such SPC shall not be entitled to payments under Sections 2.13, 2.15 or 2.19 in amounts greater than the Granting Lender would have been entitled to in the absence of such funding by the SPC and (iv) with respect to a SPC of a Canadian Lender, such SPC shall be a resident of Canada for the purposes of the ITA. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper 90 or other senior Indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof or the laws of Canada or any Province thereof. In addition, notwithstanding anything to the contrary contained in this Section 9.04, any SPC may (i) with notice to, but without the prior written consent of, the Borrowers and the Applicable Administrative Agent and without paying any processing fee therefore, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the U.S. Borrower or the Canadian Borrower, as applicable, and the Applicable Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC, provided that such SPC makes such recipient aware of the confidentiality provisions of Section 9.16. (j) Neither Borrower shall assign or delegate any of its rights or duties hereunder without the prior written consent of the Applicable Administrative Agent, the Applicable Issuing Bank and each Lender, and any attempted assignment without such consent shall be null and void. SECTION 9.05. EXPENSES; INDEMNITY. (a) The Borrowers agree, jointly and severally, to pay all reasonable out-of-pocket expenses incurred by the Administrative Agents, the Collateral Agents and the Issuing Banks in connection with the syndication of the credit facilities provided for herein and the preparation and administration of this Agreement and the other Loan Documents or in connection with any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions hereby or thereby contemplated shall be consummated) or incurred by the Administrative Agents, the Collateral Agents or any Lender in connection with the enforcement or protection of its rights in connection with this Agreement and the other Loan Documents or in connection with the Loans made or Letters of Credit issued hereunder, including the reasonable fees, charges and disbursements of Bracewell & Patterson, L.L.P., counsel for the Administrative Agent, and, in connection with any such enforcement or protection, the reasonable fees, charges and disbursements of any other counsel for the Administrative Agents, the Collateral Agents or any Lender. (b) The Borrowers agree, jointly and severally, to indemnify the Administrative Agents, the Collateral Agents, each Lender, each Issuing Bank and the Related Parties of any of the foregoing persons (each such person being called an "Indemnitee") against, and to hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including reasonable counsel fees, charges and disbursements but excluding any such loss, claim, damage, liability or expense resulting from a claim or proceeding brought by a Lender against any other Lender (other than any Agent in its capacity as such), incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (i) the execution or delivery of this Agreement or any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties thereto of their respective obligations 91 thereunder or the consummation of the transactions contemplated thereby, (ii) the use of the proceeds of the Loans or issuance of Letters of Credit, (iii) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto, or (iv) any actual or alleged presence or Release of Hazardous Materials on any property owned or operated by a Borrower or any of the Subsidiaries, or any Environmental Liability related in any way to a Borrower or the Subsidiaries; provided that SUCH INDEMNITY SHALL EXPRESSLY INCLUDE ANY SUCH LOSSES, LIABILITIES, CLAIMS, DAMAGES OR EXPENSE INCURRED BY REASON OF THE PERSON BEING INDEMNIFIED'S OWN NEGLIGENCE but not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or, with respect to any Environmental Liability, to the extent such Indemnitee, after foreclosure or other remedial action, has caused such Environmental Liability. (c) To the extent that the Borrowers fail to pay any amount required to be paid by them to an Agent or an Issuing Bank under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to such Agent or Issuing Bank, as the case may be, such Lender's pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent or Issuing Bank in its capacity as such. For purposes hereof, a Lender's "pro rata share" shall be determined based upon its share of the sum of the aggregate amount of the Credit Exposures and unused Total Commitment at the time. (d) To the extent permitted by applicable law, neither Borrower shall assert, and each hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, any Loan or Letter of Credit or the use of the proceeds thereof. (e) The provisions of this Section 9.05 shall remain operative and in full force and effect regardless of the expiration of the term of this Agreement, the consummation of the transactions contemplated hereby, the repayment of any of the Loans, the expiration of the Commitments, the expiration of any Letter of Credit, the invalidity or unenforceability of any term or provision of this Agreement or any other Loan Document, or any investigation made by or on behalf of any Agent, Lender or Issuing Bank. All amounts due under this Section 9.05 shall be payable on written demand therefor. SECTION 9.06. RIGHT OF SETOFF. If an Event of Default shall have occurred and be continuing, each Lender is hereby authorized at any time and from time to time, except to the extent prohibited by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other Indebtedness 92 at any time owing by such Lender to or for the credit or the account of the Borrower to whom it has made Loans against any of and all the obligations of such Borrower now or hereafter existing under this Agreement and other Loan Documents held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement or such other Loan Document and although such obligations may be unmatured. The rights of each Lender under this Section 9.06 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have. SECTION 9.07. APPLICABLE LAW. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS (OTHER THAN LETTERS OF CREDIT AND AS EXPRESSLY SET FORTH IN OTHER LOAN DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS. EACH LETTER OF CREDIT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED IN ACCORDANCE WITH, THE LAWS OR RULES DESIGNATED IN SUCH LETTER OF CREDIT, OR IF NO SUCH LAWS OR RULES ARE DESIGNATED, THE UNIFORM CUSTOMS AND PRACTICE FOR DOCUMENTARY CREDITS MOST RECENTLY PUBLISHED AND IN EFFECT, ON THE DATE SUCH LETTER OF CREDIT WAS ISSUED, BY THE INTERNATIONAL CHAMBER OF COMMERCE (THE "UNIFORM CUSTOMS") AND, AS TO MATTERS NOT GOVERNED BY THE UNIFORM CUSTOMS, THE LAWS OF THE STATE OF TEXAS. SECTION 9.08. WAIVERS; AMENDMENT. (a) No failure or delay of the Administrative Agents, the Collateral Agents, any Lender or any Issuing Bank in exercising any power or right hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agents, the Collateral Agents, the Issuing Banks and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrowers or any other Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on a Borrower in any case shall entitle the Borrowers to any other or further notice or demand in similar or other circumstances. (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrowers and the Required Lenders; provided, however, that no such agreement shall (i) decrease the principal amount of, or extend the maturity of or any scheduled principal payment date or date for the payment of any interest on any Loan or any date for reimbursement of an L/C Disbursement, or waive or excuse any such payment or any part thereof, or decrease the rate of interest on any Loan or L/C Disbursement, without the prior written consent of each Lender affected thereby, (ii) extend the Commitment or decrease or extend the date for payment of any Fees of any Lender without the prior 93 written consent of such Lender, (iii) amend or modify the pro rata requirements of Section 2.16, the provisions of Section 9.04(j), the provisions of this Section, the definition of the term "Required Lenders" or (unless expressly authorized pursuant to the terms of the Guarantee Agreements or the Security Documents) release any Guarantor or all or any substantial part of the Collateral, without the prior written consent of each Lender, (iv) change the provisions of any Loan Document in a manner that by its terms adversely affects the rights in respect of payments due to Lenders holding one Class of Loans differently from the rights in respect of payments due to Lenders holding another Class of Loans without the prior written consent of the Required U.S. Lenders (if the U.S. Lenders are the adversely affected Class) or the Required Canadian Lenders (if the Canadian Lenders are the adversely affected Class), (v) amend or modify the definition of the term "Required U.S. Lenders" or "Required Canadian Lenders" without the prior written consent of each U.S. Lender or Canadian Lender, respectively, (vi) amend or modify the protections afforded to an SPC pursuant to the provisions of Section 9.04(i) without the written consent of such SPC, or (vii) increase the aggregate Commitments without the prior written consent of each Lender, except as otherwise provided in Section 2.09(d); provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of an Administrative Agent, a Collateral Agent or an Issuing Bank hereunder or under any other Loan Document without the prior written consent of such Administrative Agent, Collateral Agent or Issuing Bank, respectively. Notwithstanding the foregoing, if either Borrower shall request the release of any Collateral to be sold as part of any Asset Sale permitted under Section 6.05 and shall deliver to the Applicable Collateral Agent a certificate to the effect that such Asset Sale will comply with the terms of this Agreement, the Applicable Collateral Agent, if satisfied that the applicable certificate is correct, shall and is hereby authorized to, without the consent of any Lender, execute and deliver all such instruments as may be required to effect the release of such Collateral. SECTION 9.09. INTEREST RATE LIMITATION. (a) Regardless of any provisions contained in this Agreement or in any other Loan Documents, the Lenders shall never be deemed to have contracted for or be entitled to receive, collect or apply as interest on any Loan or participation in any L/C Disbursement any amount in excess of the maximum lawful rate (the "Maximum Rate"), and in the event any Lender ever receives, collects or applies as interest (whether termed interest herein or deemed to be interest by operation of law or judicial determination) any such excess, or if an acceleration of the maturities of the Loans or if any prepayment by any Borrower results in such Borrower having paid any interest in excess of the Maximum Rate, such amount which would be excessive interest shall be deemed to be a partial prepayment of principal and applied to the reduction of the unpaid principal balance of the Loans for which such excess was received, collected or applied, and, if the principal amount of the Obligations is paid in full, any remaining excess shall forthwith be paid to the applicable Borrower. All sums paid or agreed to be paid to the Lenders for the use, forbearance or detention of the Obligations evidenced by this Agreement shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread, in equal or unequal parts, throughout the full term of such Obligations until payment in full so that the rate or amount of interest on account of such indebtedness does not exceed the Maximum Rate. In determining whether or not the interest paid or payable under any specific contingency exceeds the 94 Maximum Rate of interest permitted by law, the Borrowers and the Lenders shall, to the maximum extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium, rather than as interest; and (ii) exclude voluntary prepayments and the effect thereof; and (iii) compare the total amount of interest contracted for, charged or received with the total amount of interest which could be contracted for, charged or received throughout the entire contemplated term of the Loans at the Maximum Rate. (b) For purposes of Section 303 of the Texas Finance Code, to the extent applicable to any Lender or Agent, Borrower agrees that the Maximum Rate (as defined herein) shall be the "weekly ceiling" as defined in said Chapter, provided that such Lender or Agent, as applicable, may also rely, to the extent permitted by applicable laws of the State of Texas and the United States of America, on alternative maximum rates of interest under the Texas Finance Code or other laws applicable to such Lender or Agent from time to time if greater. SECTION 9.10. ENTIRE AGREEMENT. PURSUANT TO SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE, A CREDIT AGREEMENT IN WHICH THE AMOUNT INVOLVED IN THE CREDIT AGREEMENT EXCEEDS $50,000 IN VALUE IS NOT ENFORCEABLE UNLESS THE CREDIT AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT PARTY'S AUTHORIZED REPRESENTATIVE. THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE PRECEDING SENTENCE SHALL BE DETERMINED SOLELY FROM THE WRITTEN CREDIT AGREEMENT, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED INTO THE CREDIT AGREEMENT. THIS WRITTEN CREDIT AGREEMENT AND THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. Nothing in this Agreement or in the other Loan Documents, expressed or implied, is intended to confer upon any person (other than the parties hereto and thereto, their respective successors and assigns permitted hereunder (including any Affiliate of an Issuing Bank that issues any Letter of Credit) and, to the extent expressly contemplated hereby, the Related Parties of each Agent, Issuing Bank and Lender) any rights, remedies, obligations or liabilities under or by reason of this Agreement or the other Loan Documents. SECTION 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE 95 FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11. SECTION 9.12. SEVERABILITY. In the event any one or more of the provisions contained in this Agreement or in any other Loan Document should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. SECTION 9.13. COUNTERPARTS. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original but all of which when taken together shall constitute a single contract, and shall become effective as provided in Section 9.03. Delivery of an executed signature page to this Agreement by facsimile transmission shall be as effective as delivery of a manually signed counterpart of this Agreement. SECTION 9.14. HEADINGS. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement. SECTION 9.15. JURISDICTION; CONSENT TO SERVICE OF PROCESS (a) Each of the Borrowers hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of (i) any Texas state court or Federal court of the United States of America sitting in the Harris County, Texas and (ii) in the case of the Canadian Borrower, the courts of the Provinces of Ontario and Alberta, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or the other Loan Documents, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that, to the extent permitted by law, all claims in respect of any such action or proceeding may be heard and determined in any such court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement shall affect any right that an Administrative Agent, a Collateral Agent, an Issuing Bank or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or the other Loan Documents against the Borrowers or their respective properties in the courts of any jurisdiction. 96 (b) Each of the Borrowers hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or the other Loan Documents in any such provincial, Texas State or Federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. (c) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law. SECTION 9.16. CONFIDENTIALITY. Each of the Administrative Agents, the Collateral Agents, the Issuing Banks and the Lenders agrees to maintain and to cause their respective Related Parties to maintain, the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates' officers, directors, employees and agents, including accountants, legal counsel and other advisors (it being understood that the persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority or quasi-regulatory authority (such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) in connection with the exercise of any remedies hereunder or under the other Loan Documents or any suit, action or proceeding relating to the enforcement of its rights hereunder or thereunder, (e) subject to an agreement containing provisions substantially the same as those of this Section 9.16, to (i) any actual or prospective assignee of or participant in any of its rights or obligations under this Agreement and the other Loan Documents or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to a Borrower or any Subsidiary or any of their respective obligations, (f) with the consent of the Borrowers or (g) to the extent such Information becomes publicly available other than as a result of a breach of this Section 9.16. For the purposes of this Section, "Information" shall mean all information received from a Borrower and related to a Borrower or its business, other than any such information that was available to an Administrative Agent, a Collateral Agent, any Issuing Bank or any Lender on a nonconfidential basis from a source that is not in breach of its obligations of confidentiality to a Borrower; provided that, in the case of Information received from a Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any person required to maintain the confidentiality of Information as provided in this Section 9.16 shall be considered to have complied with its obligation to do so if such person has exercised the same degree of care to maintain the confidentiality of such Information as such person would accord its own confidential information. Notwithstanding anything herein to the contrary, "Information" shall not include, and the Agents and each Lender may disclose to any and all persons, without limitation of any kind, any information with respect to the "tax treatment" and "tax structure" (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including 97 opinions or other tax analyses) that are provided to such Agent or such Lender relating to such tax treatment and tax structure; provided that with respect to any document or similar item that in either case contains information concerning the tax treatment or tax structure of the transaction as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to the tax treatment or tax structure of the Loans, Letters of Credit and transactions contemplated hereby. SECTION 9.17. JUDGMENT CURRENCY. (a) The obligations of the Borrowers and the other Loan Parties hereunder and under the other Loan Documents to make payments in U.S. dollars or Canadian dollars (the "Obligation Currency") shall not be discharged or satisfied by any tender or recovery pursuant to any judgment expressed in or converted into any currency other than the Obligation Currency, except to the extent that such tender or recovery results in the effective receipt by the Applicable Administrative Agent or a Lender or an Issuing Bank of the full amount of the Obligation Currency expressed to be payable to such Administrative Agent, Lender or Issuing Bank under this Agreement or the other Loan Documents. If, for the purpose of obtaining or enforcing judgment against a Borrower or any other Loan Party or in any court or in any jurisdiction, it becomes necessary to convert into or from any currency other than the Obligation Currency (such other currency being hereinafter referred to as the "Judgment Currency") an amount due in the Obligation Currency, the conversion shall be made at the Canadian Dollar Equivalent or U.S. Dollar Equivalent, or, in the case of other currencies, the rate of exchange (as quoted by the Administrative Agent or if the Administrative Agent does not quote a rate of exchange on such currency, by a known dealer in such currency designated by the Administrative Agent) determined, in each case, as of the date immediately preceding the day on which the judgment is given (such Business Day being hereinafter referred to as the "Judgment Currency Conversion Date"). (b) If there is a change in the rate of exchange prevailing between the Judgment Currency Conversion Date and the date of actual payment of the amount due, each Borrower covenants and agrees to pay, or cause to be paid, as a separate obligation and notwithstanding any judgment, such additional amounts, if any (but in any event not a lesser amount), as may be necessary to ensure that the amount paid in the Judgment Currency, when converted at the rate of exchange prevailing on the date of payment, will produce the amount of the Obligation Currency which could have been purchased with the amount of Judgment Currency stipulated in the judgment or judicial award at the rate of exchange prevailing on the Judgment Currency Conversion Date.
