Each Borrower may borrow Loans on any Business Day; provided that such Borrower shall notify the Applicable Administrative Agent by telephone of the Borrowing (the “Borrowing Request”) not later than 2:00 p.m., New York City time (a) three (3) Business Days prior to the Borrowing Date, in the case of Eurodollar Loans, and (b) the Borrowing Date, in the case of Alternate Base Rate Loans, Canadian Base Rate Loans or Canadian Prime Rate Loans. Each telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Applicable Administrative Agent of a written Borrowing Request in a form approved by the Applicable Administrative

Agent and signed by the Requesting Borrower. Each such telephonic and written Borrowing Request shall specify (i) the amount to be borrowed, (ii) the Borrowing Date, (iii) whether the Borrowing is to consist of Eurodollar Loans, Alternate Base Rate Loans, Canadian Base Rate Loans, Canadian Prime Rate Loans, or a combination thereof (in each case stating the amounts and currency requested), (iv) in the case of Eurodollar Loans, the length of the Interest Period(s) therefor, and (v) the location and number of the Requesting Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.12. Each Borrowing shall be in an aggregate principal amount not less than the lesser of (i) $10,000,000 or a whole multiple of $5,000,000 in excess thereof, and (ii) the then unused Commitments available to the Requesting Borrower. Upon receipt of such notice, the Applicable Administrative Agent shall promptly notify each Applicable Lender thereof. Each Applicable Lender will make the amount of its pro rata share of each Borrowing available to the Applicable Administrative Agent for the account of the Requesting Borrower in accordance with Section 2.12. The proceeds of each such Borrowing of Revolving Loans will be made available to the Requesting Borrower by the Applicable Administrative Agent in accordance with Section 2.12. Notwithstanding the foregoing, all Borrowings by way of Bankers’ Acceptances and BA Loans shall be made pursuant to Section 2.24.

     Section 2.04 Facility Fees, Utilization Fees and LC Fees.

          (a) Subject to Section 2.04(e), each Applicable Borrower agrees to pay to the Applicable Administrative Agent for the account of each Applicable Lender a Facility Fee from the Effective Date to, but not including, the Maturity Date or such earlier date upon which the Commitments shall terminate or be reduced to zero as provided herein, computed at the Facility Fee Rate on the daily amount of the Commitment of such Lender (whether used or unused) (the “Facility Fee”); provided that, if such Lender continues to have any Credit Exposure after its Commitment terminates, then such Facility Fee shall continue to accrue on the daily amount of such Lender’s Credit Exposure from and including the date on which its Commitment terminates to, but not including, the date on which such Lender ceases to have any Credit Exposure.

          (b) Subject to Section 2.04(e), the Applicable Borrower agrees to pay to the Applicable Administrative Agent for the account of each Applicable Lender at all times when the Combined Credit Exposure is greater than or equal to 50% of the availability under the total Commitment a Utilization Fee computed at the Utilization Fee Rate on the daily amount of the Credit Exposure of such Lender (the “Utilization Fee”).

          (c) Reserved.

          (d) Each Applicable Borrower agrees to pay (i) to the Applicable Administrative Agent for the account of each Applicable Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same rate as the Eurodollar Margin on the average daily amount of such Lender’s LC Exposure to such Borrower (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to any Issuing Bank an issuing fee payable on the date a Letter of Credit is issued, which shall be the normal issuing fee for letters of credit issued by such Issuing Bank, not to be less

than the greater of $500 or 0.0125% times the face amount of such Letter of Credit (collectively, the “LC Fees”).

          (e) If any Lender shall become a Defaulting Lender, then, notwithstanding Section 2.04(a) and Section 2.04(b) above and without prejudicing any right or remedy that any Borrower may have with respect to, on account of, arising from or relating to any event pursuant to which such Lender shall be a Defaulting Lender, no Facility Fee or Utilization Fee shall accrue for the account of such Lender from and after the date upon which such Lender shall have become a Defaulting Lender.

          (f) Facility Fees, Utilization Fees and LC Fees shall be payable quarterly in arrears on the last day of each March, June, September and December, commencing on September 30, 2004, and on the Maturity Date or, with respect to Facility Fees, on such earlier date as the Commitments shall terminate or be reduced to zero as provided herein. All accrued Facility Fees, Utilization Fees and LC Fees which are not paid on or before the Maturity Date shall be due and payable on demand.

     Section 2.05 Letters of Credit.

          (a) Subject to the terms and conditions set forth herein, each Borrower may request the issuance of Letters of Credit for its own account, in a form reasonably acceptable to the Applicable Administrative Agent and the Issuing Bank, at any time and from time to time prior to the Revolving Commitment Termination Date. In the event of (i) any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Requesting Borrower to, or entered into by the Requesting Borrower with, an Issuing Bank relating to any Letter of Credit, or (ii) any terms and conditions supplemental to the terms and conditions of this Agreement contained in any such form of letter of credit application or such other agreement, in each case, the terms and conditions of this Agreement shall control and such supplemental terms and conditions shall be ignored.

          (b) To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Requesting Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the appropriate Issuing Bank and the Administrative Agents (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with Section 2.05(c)), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information (including, if applicable, the currency of such Letter of Credit, which shall be US Dollars or Canadian Dollars) as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by an Issuing Bank, the Requesting Borrower also shall submit a letter of credit application on such Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Requesting Borrower shall be deemed to represent and

warrant that), after giving effect to such issuance, amendment, renewal or extension and the continuation of an Existing Letter of Credit hereunder (i) the LC Exposure shall not exceed the unused Commitment available under the applicable Tranche and (ii) the sum of the Combined Credit Exposure shall not exceed the sum of the total Commitments; provided that the Issuing Bank shall not issue, amend, renew or extend any Letter of Credit if the Issuing Bank shall have received written notice (which has not been rescinded) from the Applicable Administrative Agent or any Lender that any applicable condition precedent to the issuance, amendment, renewal or extension of such Letter of Credit has not been satisfied at the requested time of issuance, amendment, renewal or extension of such Letter of Credit.

          (c) Each Letter of Credit shall expire at or prior to the close of business on the date selected by the Requesting Borrower, which shall not be later than the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension), and (ii) the date that is five (5) Business Days prior to the Maturity Date.

          (d) By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and the continuation hereunder of each of the Existing Letters of Credit and without any further action on the part of an Issuing Bank or the Applicable Lenders, such Issuing Bank hereby grants to each Applicable Lender, and each such Lender hereby acquires from such Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Applicable Lender hereby absolutely and unconditionally agrees to pay to the Applicable Administrative Agent, for the account of such Issuing Bank in the currency in which such Letter of Credit is denominated, such Lender’s Applicable Percentage of each LC Disbursement made by such Issuing Bank and not reimbursed by the Applicable Borrower on the date due as provided in Section 2.05(e), or of any reimbursement payment required to be refunded to such Applicable Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of an Event of Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

          (e) If an Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Applicable Borrower shall reimburse such LC Disbursement in the currency in which such Letter of Credit is denominated by paying to the Applicable Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on (i) the Business Day that such Applicable Borrower receives a notice of such LC Disbursement from the Applicable Administrative Agent, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that such Applicable Borrower receives a notice of such LC Disbursement from the Applicable Administrative Agent, if such notice is not received prior to such time on the day of receipt; provided that, with respect to any such payment owing by the Applicable Borrower prior to the Revolving Commitment Termination Date, such Applicable Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.03 that such

payment be financed with an Alternate Base Rate Borrowing, in the case of the US Borrower, or a Canadian Prime Rate Borrowing or Canadian Base Rate Borrowing, in the case of the Canadian Borrower, in an equivalent amount and, to the extent so financed, the Applicable Borrower’s obligation to make such payment shall be discharged and replaced by the resulting Borrowing. If the Applicable Borrower fails to make such payment when due, the Applicable Administrative Agent shall notify each Applicable Lender of the applicable LC Disbursement, the payment then due from such Applicable Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Applicable Lender shall pay to the Applicable Administrative Agent its Applicable Percentage of the payment then due from the Applicable Borrower, in the same manner as provided in Section 2.12 with respect to Loans made by such Lender in the appropriate currency (and Section 2.12 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Applicable Administrative Agent shall promptly pay to such Issuing Bank the amounts so received by such Applicable Administrative Agent from the Applicable Lenders. Promptly following receipt by the Applicable Administrative Agent of any payment from an Applicable Borrower pursuant to this paragraph, the Applicable Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that the Applicable Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by an Applicable Lender pursuant to this paragraph to reimburse an Issuing Bank for any LC Disbursement shall not constitute a Loan and shall not relieve the Applicable Borrower of its obligation to reimburse such LC Disbursement.

          (f) To the extent permitted by law, each Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.05(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, such Borrower’s obligations hereunder. To the extent permitted by law, none of the Administrative Agents, the Lenders, or the Issuing Banks, or any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of an Issuing Bank; provided that the foregoing shall not be construed to excuse any Issuing Bank from liability to an Applicable 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 exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. To the extent permitted by law, the

parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of an Issuing Bank, such Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

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

          (h) If an Issuing Bank shall make any LC Disbursement, then, unless the Applicable Borrower shall reimburse such LC Disbursement in full on the date specified in Section 2.05(e), the unpaid amount thereof shall bear interest, for each day from and including the date such reimbursement is due pursuant to Section 2.05(e) to but excluding the date that such Applicable Borrower reimburses such LC Disbursement, at the rate per annum then applicable to Alternate Base Rate Loans, in the case of Letters of Credit issued for the account of the US Borrower, and Canadian Base Rate Loans or Canadian Prime Rate Loans, as applicable, in the case of Letters of Credit issued for the account of the Canadian Borrower; provided that, if an Applicable Borrower fails to reimburse such LC Disbursement when due pursuant to Section 2.05(e), then the provisions of Section 2.10(a) pertaining to interest payable on overdue principal shall apply. Interest accrued pursuant to this paragraph shall be for the account of the applicable Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.05(e) to reimburse such Issuing Bank shall be for the account of such Lender to the extent of such payment.

          (i) Any Issuing Bank with respect to a Tranche may be replaced at any time by written agreement among the Applicable Borrower, the Applicable Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Applicable Administrative Agent shall notify the Applicable Lenders of any such replacement of an Issuing Bank. At the time any such replacement shall become effective, the Applicable Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank. From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter, and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank with respect to the Canadian Tranche or the US Tranche, as the case may be, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of any Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this

Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

          (j) (i) If any Event of Default shall occur and be continuing, on the Business Day that an Applicable Borrower receives notice from Lenders with LC Exposure representing greater than 66²/³% of the total LC Exposure or, if the maturity of the Loans has been accelerated, from the Applicable Administrative Agent or the Majority Lenders, demanding the deposit of cash collateral pursuant to this paragraph, and (ii) on the Business Day that an Applicable Borrower receives notice from either the Administrative Agent acting alone or the Majority Lenders demanding deposit of cash collateral pursuant to Section 2.08(b) (or, if such notice is received on a day other than a Business Day, on the next Business Day following receipt of such notice), the Applicable Borrower shall deposit in an account with the Applicable Administrative Agent, in the name of the Applicable Administrative Agent and for the benefit of the Applicable Lenders, an amount in cash (in the applicable currency) equal to the US LC Exposure or the Canadian LC Exposure, as applicable, as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Applicable Borrower described in Section 7.01(g) and Section 7.01(h). Such deposit shall be held by the Applicable Administrative Agent as collateral for the payment and performance of the obligations of the Applicable Borrower under this Agreement. The Applicable Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made in certificates of deposits of the Applicable Administrative Agent or securities backed by the full faith and credit of the United States of America or Canada, at the option of the Applicable Administrative Agent and at the Applicable Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Monies in such account shall be applied by the Applicable Administrative Agent to reimburse each applicable Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Applicable Borrower for the US LC Exposure or the Canadian LC Exposure, as applicable, at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of the Majority Lenders), be applied to satisfy other obligations of such Applicable Borrower under this Agreement. If an Applicable Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to such Applicable Borrower within two (2) Business Days after all Events of Default have been cured or waived.

          (k) The Existing Letters of Credit shall automatically be deemed to have been issued under this Agreement as of the Effective Date, and except as otherwise indicated herein, the terms and provisions of the Existing Credit Agreement shall thereafter have no force or effect with respect thereto.

     Section 2.06 Reduction or Termination of Commitments. Unless previously terminated, the Commitments shall terminate on the Revolving Commitment Termination Date. The US Borrower shall have the right, upon not less than two (2) Business Days’ notice to the

Applicable Administrative Agent, to terminate the US Tranche Commitments or the Canadian Tranche Commitments, as applicable, or, from time to time, reduce the amount of the US Tranche Commitments or the Canadian Tranche Commitments, as applicable; provided, however, that the US Borrower shall not terminate or reduce any Commitment if, after giving effect to any concurrent repayment of the Loans in accordance with Section 2.07 and Section 2.08 the sum of the Combined Credit Exposures would exceed the sum of total Commitments. Any reduction shall be accompanied by prepayment of the Loans to the extent, if any, that the sum of the Credit Exposures of the Applicable Lenders then outstanding exceeds the sum of the total US Tranche Commitments or the Canadian Tranche Commitments, as applicable, as then reduced. Any termination of the Commitments shall be accompanied by prepayment in full of the Loans then outstanding and the payment of any unpaid fees then accrued hereunder. Upon receipt of such notice, the Applicable Administrative Agent shall promptly notify each Applicable Lender thereof. Any partial reduction shall be in an amount of $5,000,000 or a whole multiple thereof and shall reduce permanently the total amount of the US Tranche Commitments or the Canadian Tranche Commitments, as applicable, and the Commitments then in effect, together with a corresponding reduction in the aggregate amount of each Lender’s applicable Commitment. The Commitments once terminated or reduced may not be reinstated. Each reduction of the US Tranche Commitments or the Canadian Tranche Commitments, as the case may be, shall be made ratably among the Applicable Lenders in accordance with their US Tranche Commitments or Canadian Tranche Commitments, as the case may be.

     Section 2.07 Optional Prepayments.

          (a) Each Borrower may, at its option, as provided in this Section 2.07, at any time and from time to time prepay the Loans payable by such Borrower, in whole or in part, upon at least two (2) Business Days’ prior notice to the Applicable Administrative Agent, specifying (i) the date and amount of prepayment, and (ii) the respective amounts to be prepaid in respect of such Loans. Notwithstanding the forgoing, the Canadian Borrower shall not be permitted to prepay any Bankers’ Acceptances or BA Loans at any time. Upon receipt of such prepayment notice, the Applicable Administrative Agent shall promptly notify each Applicable Lender thereof. The payment amount specified in such notice shall be due and payable on the date specified. All prepayments pursuant to this Section 2.07 shall include accrued interest on the amount prepaid to the date of prepayment and, in the case of prepayments of Eurodollar Loans, any amounts payable pursuant to Section 2.22. The Loans shall also be subject to prepayment as provided in Section 2.06, Section 2.08 and Section 9.13.

          (b) Partial optional prepayments pursuant to this Section 2.07 shall be in an aggregate principal amount of $10,000,000 or any whole multiple of $5,000,000 in excess thereof. All prepayments of Loans pursuant to this Section 2.07 shall be without the payment by the Applicable Borrower of any premium or penalty except for amounts payable pursuant to Section 2.22.

     Section 2.08 Mandatory Prepayments. (a) If at any time the total Credit Exposures of the US Tranche Lenders or the Canadian Tranche Lenders, as the case may be, exceeds the sum of the total US Tranche Commitments or the total Canadian Tranche Commitments, respectively, the Applicable Borrower shall prepay the Loans (other than BA Loans) owing by it to such Lenders in an amount equal to such excess. Each prepayment of Loans pursuant to this Section

2.08 shall be accompanied by payment of accrued interest on the amount prepaid to the date of prepayment and, in the case of prepayments of Eurodollar Loans, any amounts payable pursuant to Section 2.22.

          (b) If, after all Loans (other than BA Loans) have been prepaid pursuant to this Section 2.08, any such excess remains as a result of LC Exposure, BA Exposure or any combination thereof, the Applicable Borrowers shall provide cash collateral (i) pursuant to Section 2.05(j)(ii), to cover any such excess caused by LC Exposure, and/or (ii) pursuant to Section 2.24(j)(ii) to cover any such excess caused by BA Exposure.

     Section 2.09 Commitment Increases; Adjustment of Tranche Commitments.

          (a) So long as no Default or Event of Default has occurred and is continuing, the US Borrower may request from time to time, that the aggregate amount of the US Tranche Lenders’ US Tranche Commitments be increased (each a “US Tranche Commitment Increase”) by delivering a Notice of US Tranche Commitment Increase; provided, however, that:

               (i) except as provided in Section 2.09(d), no US Tranche Lender’s US Tranche Commitment may ever be increased without its prior written consent;

               (ii) any Notice of US Tranche Commitment Increase must be given no later than three (3) Business Days prior to the Revolving Commitment Termination Date;

               (iii) the effective date of any US Tranche Commitment Increase (the “US Tranche Commitment Increase Effective Date”) shall be no earlier than ten (10) Business Days after receipt by the US Administrative Agent of such Notice of US Tranche Commitment Increase;

               (iv) the amount of any US Tranche Commitment Increase must be at least $10,000,000;

               (v) after giving effect to any requested US Tranche Commitment Increase, the aggregate amount of the US Tranche Commitments shall not exceed $1,250,000,000 minus the aggregate amount of the Canadian Tranche Commitments then in effect;

          (b) On each US Tranche Commitment Increase Effective Date, so long as no Default or Event of Default has occurred and is continuing and to the extent there are US Tranche Revolving Loans outstanding as of such date:

               (i) each CI Lender shall, by wire transfer of immediately available funds, deliver to the US Administrative Agent such CI Lender’s New Funds Amount for the applicable US Tranche Commitment Increase Effective Date, which amount, for each such CI Lender, shall constitute US Tranche Revolving Loans made by such CI Lender to the US Borrower pursuant to this Agreement on such US Tranche Commitment Increase Effective Date; and

               (ii) the US Administrative Agent shall, by wire transfer of immediately available funds, pay to each then Reducing Percentage Lender its Reduction Amount for such US Tranche Commitment Increase Effective Date, which amount, for each such Reducing Percentage Lender, shall constitute a prepayment by the US Borrower pursuant to Section 2.07, ratably in accordance with the respective principal amounts thereof, of the principal amounts of all then outstanding US Tranche Revolving Loans of such Reducing Percentage Lender.

          (c) So long as no Default or Event of Default has occurred and is continuing, each of the conditions set forth in Section 6.02 are satisfied as of such US Tranche Commitment Increase Effective Date and no Material Adverse Change shall exist as of such date, each US Tranche Commitment Increase shall become effective on its US Tranche Commitment Increase Effective Date and upon such effectiveness (x) the US Administrative Agent shall record in the Register each CI Lender’s information, if necessary, as provided in the Notice of US Tranche Commitment Increase and pursuant to an Administrative Questionnaire that shall be completed and delivered by each CI Lender to the US Administrative Agent on or before the US Tranche Commitment Increase Effective Date and (y) the US Administrative Agent shall distribute to each Lender (including each CI Lender) a copy of the Annex I attached to the Notice of US Tranche Commitment Increase relating to such US Tranche Commitment Increase and (z) each CI Lender identified on the Notice of US Tranche Commitment Increase for such US Tranche Commitment Increase shall be a “US Lender” for all purposes under this Agreement.

          (d) So long as no Default or Event of Default has occurred which is continuing, and subject to all of the terms and conditions hereinafter set forth, at any time during each 12-month period, the US Borrower may, by providing written notice to the US Administrative Agent (an “Adjustment Request”), make up to a total of six requests on behalf of all of the Borrowers that the total Commitments of the Dual Lenders under one of the Tranches be increased on a pro rata basis by an amount of not less than US$10,000,000 and that simultaneous decreases be made on a pro rata basis to the unused Commitments of the Dual Lenders under the other Tranche in amounts that will result in the sum of the total Commitments of the Dual Lenders remaining unchanged after giving effect to such increases and decreases; provided, however, that (i) the effect of such changes to the Commitments of the Dual Lenders shall not result in an increase of the Canadian Tranche Commitments to an amount greater than US$300,000,000 or result in the reduction of the Canadian Tranche Commitments to an amount less than US$15,000,000 and (ii) neither the Canadian Tranche Commitments nor the US Tranche Commitments shall be reduced to an amount less than the Canadian Credit Exposure or the US Credit Exposure, as the case may be. An Adjustment Request shall set forth (x) the amount of the requested increase in the Commitments of the Dual Lenders under one of the Tranches (each, a “Commitment Increase (Reallocation)”), (y) the amount of the requested decreases in the Commitments of the Dual Lenders under the other Tranche which shall correspond to each Commitment Increase (Reallocation) (each a “Commitment Decrease (Reallocation)”), and (z) the date on which such adjustments are requested to become effective (which shall be not less than 5 Business Days or more than 30 days after the date of such Adjustment Request) (the “Adjustment Effective Date”). On each Adjustment Effective Date, the US Borrower, on behalf of each of the Borrowers, shall deliver to the US Administrative Agent a Section 2.09 Certificate. Subject to Section 2.09(g), all such Adjustment Requests shall become effective on the designated Adjustment Effective Date.

          (e) If either Administrative Agent receives a Borrowing Request with a Borrowing Date that coincides with an Adjustment Effective Date set forth in an Adjustment Request, such Borrowing Request shall be given effect in accordance with all of the terms and conditions set forth herein after giving effect to the Commitment Increases (Reallocation) and Commitment Decreases (Reallocation) set forth in such Adjustment Request.

          (f) Commitment Increases (Reallocation), Commitment Decreases (Reallocation) and new Commitments created pursuant to Section 2.09(d) shall become effective on the Adjustment Effective Date or US Tranche Commitment Increase Effective Date, as applicable. Subject to Section 2.09(g) hereof, the US Administrative Agent and the Lenders, including the Dual Lenders, shall have no discretion in granting requests made under an Adjustment Request.

          (g) Notwithstanding the foregoing, no increase in the Commitments of the Dual Lenders under either Tranche shall become effective under this Section, unless (i) the US Borrower shall not have withdrawn its Adjustment Request by written notice to the US Administrative Agent not less than three Business Days prior to the Adjustment Effective Date, and (ii) on the Adjustment Effective Date of each Commitment Increase (Reallocation), the US Borrower shall have delivered to the Administrative Agents a certificate substantially in the form of Exhibit F (each, a “Section 2.09 Certificate”) dated as of such Adjustment Effective Date, executed by a responsible officer of the US Borrower, on behalf of each of the Borrowers, certifying that, as of such Adjustment Effective Date, all conditions set forth in Section 6.02 (with respect to such Commitment Increase (Reallocation) rather than a Borrowing) have been satisfied.

          (h) Notwithstanding the foregoing, adjustments pursuant to Section 2.09(d) shall only be applicable to the Commitments of the Dual Lenders and shall not affect any outstanding Commitments of a Lender that is not a Dual Lender.

     Section 2.10 Interest.

          (a) Each US Dollar Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto on the unpaid Principal Amount thereof at a rate per annum equal to the US Dollar LIBO Rate for such Interest Period plus the Eurodollar Margin for such day. Each Alternate Base Rate Loan shall bear interest on the unpaid Principal Amount thereof at a fluctuating rate per annum equal to the Alternate Base Rate. Each Canadian Dollar Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto on the unpaid Principal Amount thereof at a rate per annum equal to the Canadian Dollar LIBO Rate for such Interest Period plus the Eurodollar Margin for such day. Each Canadian Prime Rate Loan shall bear interest on the unpaid Principal Amount thereof at a fluctuating rate per annum equal to the Canadian Prime Rate. Each Canadian Base Rate Loan shall bear interest on the unpaid Principal Amount thereof at a fluctuating rate per annum equal to the Canadian Base Rate. Any overdue principal of any Loan shall, without limiting the rights of any Lender under ARTICLE VII, bear interest at a rate per annum which is two percent (2%) above the rate which would otherwise be applicable to such Loan pursuant to whichever of the four preceding sentences shall apply until paid in full (as well after as before judgment). Interest shall be

payable in arrears on each Interest Payment Date; provided, however, that interest payable on overdue principal shall be payable on demand.

          (b) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Loan, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Applicable Borrower may elect to continue such Borrowing to a different Type or to continue such Borrowing for an additional Interest Period (and elect Interest Periods therefor), all as provided in this Section. The Applicable Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Applicable Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall then and thereafter be considered a separate Borrowing.

          (c) To make an election pursuant to this Section, the Applicable Borrower shall notify the Applicable Administrative Agent of such election (the “Interest Election Request”) by telephone by the time that a Borrowing Request would be required under Section 2.03 if such Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Applicable Administrative Agent of a written Interest Election Request in a form approved by the Applicable Administrative Agent and signed by the Applicable Borrower.

          (d) Each telephonic and written Interest Election Request shall identify the Applicable Borrower and specify the following information in compliance with Section 2.03:

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

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

               (iii) whether the resulting Borrowing is to be an Alternate Base Rate Borrowing, a Canadian Prime Rate Borrowing, a Canadian Base Rate Borrowing or a Eurodollar Borrowing; and

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, whether such Borrowing is to be comprised of US Dollar Eurodollar Loans or Canadian Dollar Eurodollar Loans, as applicable, and the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

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

          (f) Promptly following receipt of an Interest Election Request, the Applicable Administrative Agent shall advise each Applicable Lender of the details thereof and of such Lender’s obligation with respect to each resulting Borrowing.

          (g) If the Applicable Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Loan prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be continued as an Alternate Base Rate Loan, in the case of Eurodollar Loans made to the US Borrower, and Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan (if in Canadian Dollars), in the case of Eurodollar Loans made to the Canadian Borrower. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Applicable Administrative Agent, at the request of the Majority Lenders, so notifies the Applicable Borrower, then, so long as such Event of Default is continuing (i) no outstanding Borrowing may be continued as a Eurodollar Loan, and (ii) unless repaid, each Eurodollar Loan shall be continued as an Alternate Base Rate Loan, in the case of Eurodollar Loans made to the US Borrower, and a Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan (if in Canadian Dollars), in the case of Eurodollar Loans made to the Canadian Borrower, at the end of the Interest Period applicable thereto.

     Section 2.11 Computation of Interest and Fees.

          (a) Interest on Alternate Base Rate Loans, Canadian Prime Rate Loans, Canadian Base Rate Loans and fees shall be calculated on the basis of a 365- (or 366- as the case may be) day year for the actual days elapsed. Interest on Eurodollar Loans shall be calculated on the basis of a 360-day year for the actual days elapsed. The Applicable Administrative Agent shall notify the Applicable Borrower and the Applicable Lenders of each determination of a US Dollar LIBO Rate or a Canadian Dollar LIBO Rate. Any change in the interest rate resulting from a change in the Alternate Base Rate, Canadian Prime Rate or the Canadian Base Rate shall become effective as of the opening of business on the day on which such change in the applicable rate shall become effective. The Applicable Administrative Agent shall notify the Applicable Borrower and the Applicable Lenders of the effective date and the amount of each such change in the Alternative Base Rate, Canadian Prime Rate and the Canadian Base Rate.

          (b) The Applicable Administrative Agent shall, at the request of the Applicable Borrower, deliver to such Applicable Borrower a statement showing the computations used by the Applicable Administrative Agent in determining any interest rate pursuant to Section 2.11(a).

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

          (d) The principle of deemed reinvestment shall not apply to the calculation of interest or payment of fees or other amounts hereunder, and all interest and fees payable by a Borrower to the Lenders, shall accrue from day to day, computed as described herein in accordance with the “nominal rate” method of interest calculation.

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

     Section 2.12 Funding of Borrowings.

          (a) Each Lender shall make each Loan to be made by it hereunder on the proposed Borrowing Date thereof by wire transfer of immediately available funds by 11:30 a.m., New York City time, to the account of the Applicable Administrative Agent most recently designated by it for such purpose by notice to the Applicable Lenders, which Loan shall be in the appropriate currency (based on the relevant Borrowing Request). The Applicable Administrative Agent will make such Loans available to the Requesting Borrower by promptly crediting the amounts so received, in like funds, to an account of such Requesting Borrower designated by such Requesting Borrower in the applicable Borrowing Request; provided that Alternate Base Rate Loans, Canadian Base Rate Loans or Canadian Prime Rate Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.05(e) shall be remitted by the Applicable Administrative Agent to the Issuing Bank; and provided further that any Canadian Prime Rate Loan or any Canadian Base Rate Loan made to refinance a BA Loan pursuant to Section 2.24 shall be remitted by the Canadian Administrative Agent to the applicable Accepting Lender.

          (b) Unless the Applicable Administrative Agent shall have received notice from an Applicable Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Applicable Administrative Agent such Lender’s share of such Borrowing, the Applicable Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.12(a) and may, in reliance upon such assumption, make available to the Requesting Borrower a corresponding amount. In such event, if an Applicable Lender has not in fact made its share of the applicable Borrowing available to the Applicable Administrative Agent, then each such Lender and the Requesting Borrower severally agree to pay to the Applicable Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Requesting Borrower to but excluding the date of payment to the Applicable Administrative Agent, at (i) in the case of such Lender, the greater of the cost incurred by the Applicable Administrative Agent for making such Lender’s share of such Borrowing and a rate determined by the Applicable Administrative Agent in accordance with banking industry rules on interbank compensation, or (ii) in the case of a Requesting Borrower, the interest rate applicable to Alternate Base Rate Loans or Canadian Base Rate Loans, as applicable. If such Lender pays such amount to the Applicable Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

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

     Section 2.13 Pro Rata Treatment and Payments.

          (a) Each Borrowing by an Applicable Borrower from the Applicable Lenders, each payment (including each prepayment) by an Applicable Borrower on account of the principal of and interest on the Loans and on account of any fees hereunder, any reimbursement of LC Disbursements, and any reduction of the Commitments of the Lenders hereunder shall be made pro rata according to the US Tranche Commitments or the Canadian Tranche Commitments, as applicable, except that (i) payments or prepayments, and offsets against or reductions from the amount of payments and prepayments, in each case, specifically for the account of a particular Lender under the terms of Section 2.04, Section 2.09(b), Section 2.14, Section 2.15, Section 2.16, Section 2.22, Section 9.03 or Section 9.13 shall be made for the account of such Lender, (ii) payments of interest on BA Loans shall be made for the account of the Lenders making such Loans (it being recognized that interest on such Loans are payable in arrears while Stamping Fees on the Bankers’ Acceptance for which such BA Loan is a substitute are payable in advance, and Bankers’ Acceptances are discounted on the applicable Acceptance Date), and (iii) if any Lender shall become a Defaulting Lender, from and after the date upon which such Lender shall have become a Defaulting Lender, any payment made on account of principal of or interest on the Loans shall be applied, first for the account of the Lenders other than the Defaulting Lender, pro rata according to the US Tranche Commitments or the Canadian Tranche Commitments, as applicable, of such Lenders, until the principal of and interest on the Loans of such Lenders shall have been paid in full and, second for the account of such Defaulting Lender, provided that the application of such payments in accordance with this clause (iii) shall not constitute an Event of Default or a Default, and no payment of principal of or interest on the Loans of such Defaulting Lender shall be considered to be overdue for purposes of Section 2.10(a), if, had such payments been applied without regard to this clause (iii), no such Event of Default or Default would have occurred and no such payment of principal of or interest on the Loans of such Defaulting Lender would have been overdue. All payments (including prepayments) to be made by a Borrower on account of principal, interest, reimbursement of LC Disbursements and fees shall be made in immediately available funds without setoff or counterclaim and shall be made to the Applicable Administrative Agent on behalf of the Applicable Lenders at the Applicable Administrative Agent’s office as notified to the US Borrower from time to time at least five (5) Business Days before any change in such office. On the date of this Agreement, the office of the Applicable Administrative Agent is located (i) in the case of Canadian Prime Rate Loans, Canadian Base Rate Loans, and fees, for the account of the Domestic Lending Offices of the Lenders, (A) with respect to the Canadian Administrative Agent, at 200 Bay Street, Royal Bank Plaza, Floor 18, Toronto, M5J 2J2, Canada, Attention: Amanda Staff (Telecopy No.  ###-###-####), with a copy to JPMorgan Chase Bank, Loan and Agency Services Group, 1111 Fannin, 10th Floor, Houston, Texas 77002, Attention of Karla Contreras, Phone No.: (713)  ###-###-####, Facsimile No.: (713)  ###-###-#### and (B) in the case of Alternate Base Rate Loans and Eurodollar Loans, for the account of the Eurodollar Lending Offices or Domestic Lending Offices, as the case may be, of the Lenders which shall then be maintaining Eurodollar Loans, in each case in US Dollars (or Canadian Dollars in the case of payments relating to Loans, Letters of Credit, Bankers’ Acceptances or other Credit Exposure denominated in Canadian Dollars), with respect to the US Administrative Agent, at JPMorgan Chase Bank, Loan and Agency Services Group, 1111 Fannin, 10th Floor, Houston, Texas 77002, Attention of Karla Contreras, Phone No.: (713)  ###-###-####, Facsimile No.: (713)  ###-###-#### at or before 12:00 noon (New York City time), and (ii) JPMorgan Chase Bank, Loan and Agency

Services Group, 1111 Fannin, 10th Floor, Houston, Texas 77002, Attention of Karla Contreras, Phone No.: (713)  ###-###-####, Facsimile No.: (713)  ###-###-#### at or before 12:00 noon (New York City time). The Applicable Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. Reimbursement of all LC Disbursements shall be made as required by Section 2.05(e).

          (b) If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day, and with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month in which event such payment shall be made on the immediately preceding Business Day.

          (c) Except as provided in Section 2.04(e), Section 2.09(b), Section 2.09(d), Section 2.14, Section 2.15, Section 2.16, Section 2.22, Section 9.03, Section 9.13, and this Section 2.13, if any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of the Loans or participations in LC Disbursements under either Tranche resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon under such Tranche than the proportion received by any other Lender with respect to the US Tranche or the Canadian Tranche, as the case may be, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements with respect to the US Tranche or the Canadian Tranche, as the case may be, of other Lenders with respect to the US Tranche or the Canadian Tranche, as the case may be, to the extent necessary so that the benefit of all such payments shall be shared by such Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by a Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to a Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrowers consent to the foregoing and agree, to the extent they may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Applicable Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of such Borrower in the amount of such participation.

          (d) Unless the Applicable Administrative Agent shall have received notice from the Applicable Borrower prior to the date on which any payment is due to the Applicable Administrative Agent for the account of the Applicable Lenders or an Issuing Bank hereunder that the Applicable Borrower will not make such payment, the Applicable Administrative Agent may assume that the Applicable Borrower has made such payment on such date in accordance

herewith and may, in reliance upon such assumption, distribute to the Applicable Lenders or any Issuing Bank, as the case may be, the amount due. In such event, if the Applicable Borrower has not in fact made such payment, then each of the Applicable Lenders or an Issuing Bank, as the case may be, severally agrees to repay to the Applicable Administrative Agent forthwith on demand the amount so distributed to such Lender or such Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Applicable Administrative Agent, at the greater of the cost incurred by the Applicable Administrative Agent for making such distributed amount and a rate determined by the Applicable Administrative Agent in accordance with banking industry rules on interbank compensation.

          (e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(d), Section 2.05(e), Section 2.09(b), Section 2.12(b) or Section 2.13(d), then the Applicable Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by such Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

     Section 2.14 Increased Cost of Loans.

          (a) If any change in any applicable law, treaty or governmental regulation after the date of this Agreement, or in the interpretation or application thereof after the date of this Agreement, or compliance by any Lender or any Issuing Bank with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made or issued after the date of this Agreement, which:

               (i) does or shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, or deposits or other liabilities in or for the account of, advances or loans by, or other credit extended by, or any other acquisition of funds by, any office of such Lender or such Issuing Bank; or

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

and the result of any of the foregoing is to increase the cost to such Lender of making, continuing or maintaining any Eurodollar Loan or BA Loan or accepting any Bankers’ Acceptance (or of maintaining its obligation to make any such Loan or BA Loan or Bankers’ Acceptance) or to increase the cost to such Lender or such Issuing Bank of participating in, issuing or maintaining any Letter of Credit or BA Loan or Bankers’ Acceptance, or to reduce any amount received or receivable by such Lender or such Issuing Bank hereunder or under any Note (whether of principal, interest, or otherwise), then, in any such case, the Applicable Borrower shall pay such Lender or such Issuing Bank, as the case may be, upon written demand being made to the Applicable Borrower by such Lender or such Issuing Bank, as the case may be, such additional amount or amounts which will compensate such Lender or such Issuing Bank, as the case may be, for such amounts as such Lender or such Issuing Bank reasonably deems to be material with respect to this Agreement, the Notes, the Letters of Credit, or the Loans hereunder, provided,

however, that if all or any such additional cost would not have been payable, or such reduction would not have occurred, but for such Lender’s or such Issuing Bank’s decision to designate a new Eurodollar Lending Office or Domestic Lending Office or refusal to change to another Eurodollar Lending Office or Domestic Lending Office as provided below, the Applicable Borrower shall have no obligation under this Section 2.14 to compensate such Lender or such Issuing Bank for such amount. Such demand shall be accompanied by a certificate of a duly authorized officer of such Lender or such Issuing Bank setting forth the amount of such payment and the basis therefor. Each Applicable Lender or an Issuing Bank shall also give written notice to the Applicable Borrower and the Applicable Administrative Agent of any event occurring after the date of this Agreement which would entitle such Lender or such Issuing Bank to compensation pursuant to this Section 2.14 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation and will designate a different Eurodollar Lending Office or a Domestic Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender. Notwithstanding the foregoing, in the event that any Lender or Issuing Bank shall demand payment pursuant to this Section 2.14, the Applicable Borrower may, upon at least two (2) Business Days’ notice to the Applicable Administrative Agent and such Lender, continue in whole (but not in part) the Eurodollar Loans of such Lender into Alternate Base Rate Loans, in the case of Eurodollar Loans made to the US Borrower, or Canadian Prime Rate Loans (if in Canadian Dollars) or Canadian Base Rate Loans (if in US Dollars), in the case of Eurodollar Loans made to the Canadian Borrower, without regard to the requirements of Section 2.10.

          (b) If any Lender or any Issuing Bank shall have reasonably determined that the adoption after the date of this Agreement of any law, rule or regulation regarding capital adequacy, or any change therein or in the interpretation or application thereof after the date of this Agreement or compliance by any Lender or any Issuing Bank with any request or directive regarding capital adequacy (whether or not having the force of law) from any central bank or governmental authority made or issued after the date of this Agreement, does or shall have the effect of reducing the rate of return on such Lender’s or such Issuing Bank’s capital, or in the capital of such Lender’s or Issuing Bank’s holding company, if any, as a consequence of its obligations hereunder to a level below that which such Lender or such Issuing Bank, or such Lender’s or such Issuing Bank’s holding company, could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such Issuing Bank’s policies and the policies of such Lender’s or such Issuing Bank’s holding company with respect to capital adequacy) by an amount reasonably deemed by such Lender to be material, then from time to time, after submission by such Lender or such Issuing Bank to the Applicable Borrower (with a copy to the Applicable Administrative Agent) of a written request therefor, the Applicable Borrower shall pay to such Lender or such Issuing Bank such additional amount or amounts as will compensate such Lender or such Issuing Bank for such reduction from and after such date the Borrower receives the request; provided, however, that the foregoing shall not apply to any capital adequacy requirement imposed solely by reason of any business combination effected after the date hereof.

          (c) A certificate of a Lender or an Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or such Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section 2.14 shall be delivered to the

Applicable Borrower and shall be prima facie evidence of the amount of such payment. The Applicable Borrower shall pay such Lender or such Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

          (d) Failure or delay on the part of any Lender or any Issuing Bank to demand compensation pursuant to this Section 2.14 shall not constitute a waiver of such Lender’s or such Issuing Bank’s right to demand such compensation; provided that the Applicable Borrower shall not be required to compensate a Lender or an Issuing Bank pursuant to this Section 2.14 for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or such Issuing Bank, as the case may be, notifies the Applicable Borrower of the change in law giving rise to such increased costs or reductions and of such Lender’s or such Issuing Bank’s intention to claim compensation therefor; provided further that, if the change in law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

     Section 2.15 Illegality. Notwithstanding anything herein contained, if any Lender shall make a good faith determination that a change in any applicable law or regulation after the date of this Agreement or in the interpretation thereof after the date of this Agreement by any authority charged with the administration thereof shall make it unlawful for such Lender to give effect to its obligations to make, continue or maintain its Eurodollar Loans under this Agreement, the obligation of such Lender to make, continue or maintain Eurodollar Loans hereunder shall be suspended for the duration of such illegality. Such Lender, by written notice to the Administrative Agents, and to the Borrowers, shall declare that such Lender’s obligation to make Eurodollar Loans and to, continue and maintain Eurodollar Loans shall be suspended, and the Applicable Borrower, on the last day of the then current Interest Period applicable to such Eurodollar Loans or portion thereof or, if such Lender so requests, on such earlier date as may be required by relevant law, shall continue such Eurodollar Loans or portion thereof as Alternate Base Rate Loans, in the case of Eurodollar Loans made to the US Borrower, and Canadian Base Rate Loans (if in US Dollars) or as Canadian Prime Rate Loans (if in Canadian Dollars) in the case of Eurodollar Loans made to the Canadian Borrower, without regard to the requirements of Section 2.10. If and when such illegality ceases to exist, such suspension shall cease and such Lender shall notify the Applicable Borrower and the Administrative Agents thereof and any Loans previously continued from Eurodollar Loans to Canadian Base Rate Loans or Canadian Prime Rate Loans pursuant to this Section 2.15 shall be continued as Loans of Types corresponding to the Loans maintained by the other Applicable Lenders on the last day of the Interest Period of the corresponding Eurodollar Loans of such other Lenders.

     Section 2.16 Taxes.

          (a) Any and all payments by or on account of any obligation of a Borrower under each Loan Document shall be made free and clear of and without deduction or withholding for any Indemnified Taxes or Other Taxes; provided that if such Borrower shall be required to deduct or withhold 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 or withholding (including deductions or withholding applicable to additional sums payable under this Section), the US Administrative Agent, the Canadian Administrative Agent, any US Tranche Lender, any Canadian Tranche Lender or any Issuing Bank (as the case may be) receives an

amount equal to the sum it would have received had no such deductions or withholding been made, (ii) such Borrower shall make such deductions or withholding, and (iii) such Borrower shall pay the full amount deducted or withheld 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 US Administrative Agent, the Canadian Administrative Agent, each US Tranche Lender and Canadian Tranche Lender and each Issuing Bank, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the US Administrative Agent, the Canadian Administrative Agent, such US Tranche Lender, Canadian Tranche Lender or such Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of such Borrower under each 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 a Borrower by a Lender or an Issuing Bank, or by the US Administrative Agent or Canadian Administrative Agent on its own behalf or on behalf of a Lender or an Issuing Bank, shall be conclusive absent manifest error.

          (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by any Borrower to a Governmental Authority, such Borrower shall deliver to the US Administrative Agent and the Canadian Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the US Administrative Agent and, if relating to the Canadian Tranche, the Canadian 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 US Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the US Borrower (with a copy to the US 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 the US Borrower as will permit such payments to be made without withholding or at a reduced rate.

          (f) For any period during which a Foreign Lender has failed to provide the US Borrower with the appropriate documentation as required by Section 2.16(e), the US Borrower shall not be obligated to pay, and such Foreign Lender shall not be entitled to secure additional amounts under this Section 2.16 with respect to Indemnified Taxes imposed by a Governmental Authority to the extent that such additional amounts would not have arisen but for such failure of such Foreign Lender.

          (g) If the US Administrative Agent, the Canadian Administrative Agent, or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by a Borrower or with respect to which a Borrower has paid additional amounts pursuant to this Section 2.16, it shall pay over such refund to such Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by such Borrower under this Section 2.16 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the US Administrative Agent, the Canadian Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, however, that such Borrower, upon the request of the US Administrative Agent, the Canadian Administrative Agent or such Lender, agrees to forthwith repay the amount paid over to such Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the US Administrative Agent, the Canadian Administrative Agent, or such Lender in the event the US Administrative Agent, the Canadian Administrative Agent, or such Lender is required to repay such refund to such Governmental Authority. Nothing contained in this Section 2.16 shall require the US Administrative Agent, the Canadian Administrative Agent, or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to any Borrower or any other Person.

     Section 2.17 Substitute Loan Basis. In the event that prior to the commencement of any Interest Period for any Eurodollar Borrowing the Majority Lenders shall reasonably determine (which determination shall be final and conclusive and binding upon the Borrowers) that (a) by reason of changes affecting the London Interbank Eurodollar Market, adequate and fair means do not exist for ascertaining the US Dollar LIBO Rate or the Canadian Dollar LIBO Rate for such requested Interest Period, or (b) the US Dollar LIBO Rate or Canadian LIBO Rate will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period then, and in any such event, the Applicable Administrative Agent shall forthwith give notice to the Applicable Borrower and, (i) unless, on the date upon which such Eurodollar Loans were to be made, such Borrower notifies the Applicable Administrative Agent that it elects not to borrow on such date, any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Alternate Base Rate Loans, in the case of the US Borrower, and as Canadian Base Rate Loans, in the case of the Canadian Borrower, (ii) any Loans that were to have been, on the first day of such Interest Period, continued as Eurodollar Loans, shall be continued as Alternate Base Rate Loans, in the case of the US Borrower, and as Canadian Base Rate Loans (if in US Dollars) or Canadian Prime Rate Loans (if in Canadian Dollars), in the case of the Canadian Borrower, on the date upon which such Loans were to have been continued, and (iii) any outstanding Eurodollar Loans shall be continued, on the last day of the Interest Period applicable thereto, as Alternate Base Rate Loans, in the case of the US Borrower, and as Canadian Base Rate Loans, in the case of the Canadian Borrower, on the date upon which such Loans are to be continued. If any Lender is required to make a Canadian Prime Rate Loan or continue a Loan as a Canadian Prime Rate Loan pursuant to subsections (i) through (iii) above, and such Lender is, for any reason, unable to access Canadian Dollars to fund such Canadian Prime Rate Loan, then such Lender shall, instead of making or continuing such Canadian Prime Rate Loan (as the case may be) pursuant to subsections (i) through (iii) above, make or continue (as the case may be) such Loan as a Canadian Base Rate Loan. The Applicable Administrative Agent shall give written notice to the Applicable Borrower of any event occurring after the giving of such notice which permits an

adequate and fair means of ascertaining the US Dollar LIBO Rate and the Canadian Dollar LIBO Rate and until such notice by the Applicable Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to continue as Eurodollar Loans.

     Section 2.18 Certain Prepayments or Continuations. If the Eurodollar Loans of any Applicable Lender are prepaid or continued as Alternate Base Rate Loans, Canadian Prime Rate Loans or Canadian Base Rate Loans pursuant to Section 2.14 or Section 2.15 (such Eurodollar Loans being herein called “Affected Loans”), unless and until such Lender gives written notice that the circumstances which gave rise to such prepayment or continuation no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) such Lender shall not make further Affected Loans and all Loans which would otherwise be made by such Lender as, or continued by such Lender into, Affected Loans shall be made instead as, or continued as Alternate Base Rate Loans, Canadian Base Rate Loans (if in US Dollars) or Canadian Prime Rate Loans (if in Canadian Dollars), as the case may be (on which interest and principal shall be payable simultaneously with the related Affected Loans of the other Applicable Lenders).

     Section 2.19 Certain Notices. Notices by a Borrower under each of Section 2.03, Section 2.05, Section 2.06, Section 2.07, Section 2.14, Section 2.17, and Section 2.10 and under the definition of “Interest Period” in Section 1.01 (a) shall be given in writing, by telecopy or by telephone (confirmed promptly in writing), and (b) shall be effective only if received by the Applicable Administrative Agent and, in the case of Section 2.14, the Lender involved, not later than 10:30 A.M. (New York City time) on the day specified in the respective Section or definition as the latest day such notice may be given. Notices by the Applicable Borrower under each of Section 2.03, Section 2.05, Section 2.06, Section 2.07, Section 2.14, Section 2.17, and Section 2.10 shall be irrevocable.

     Section 2.20 Reserved.

     Section 2.21 Minimum Amounts of Eurodollar Borrowings. All Borrowings and continuations of Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, after giving effect thereto, the aggregate Principal Amount of the Loans comprising each Eurodollar Borrowing shall be equal to $10,000,000 or a whole multiple of $5,000,000 in excess thereof.

     Section 2.22 Break Funding Payments. In the event of (a) the payment of any Principal Amount of any Eurodollar Loan or BA Loan or Bankers’ Acceptance other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the continuation of any Eurodollar Loan or BA Loan or Bankers’ Acceptance other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, continue or prepay any Loan on the date specified in any notice delivered pursuant hereto, (d) the assignment of any Eurodollar Loan or BA Loan or Bankers’ Acceptance other than on the last day of the Interest Period applicable thereto as a result of a request by the Applicable Borrower, then, in any such event, such Borrower shall compensate each Applicable Lender or each Issuing Bank for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Applicable Lender shall be deemed to include an amount determined by

such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the Principal Amount of such Loan had such event not occurred, at the US Dollar LIBO Rate or Canadian Dollar LIBO rate, as applicable (in the case of a Eurodollar Loan) that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such Principal Amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. A certificate of any such Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Applicable Borrower and the Administrative Agents and shall be conclusive absent manifest error. The Applicable Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof. Notwithstanding anything to the contrary contained herein, (y) no Lender shall be entitled to receive any amount or amounts pursuant to this Section if such amount or amounts are attributable solely to the merger or other consolidation of such Lender with another Lender and (z) nothing in this Section 2.22 shall be construed as giving rise to any right of the Canadian Borrower to prepay any Bankers’ Acceptance or BA Loans.

     Section 2.23 Currency Conversion and Currency Indemnity.

          (a) Each Borrower shall make payment relative to any obligation in the currency (the “Agreed Currency”) in which the obligation was effected. If any payment is received on account of any obligation in any currency (the “Other Currency”) other than the Agreed Currency (whether voluntarily or pursuant to an order or judgment or the enforcement thereof or the realization of any collateral or the liquidation of a Borrower or otherwise), such payment shall constitute a discharge of the liability of such Borrower hereunder and under the other Loan Documents in respect of such obligation only to the extent of the amount of the Agreed Currency which the Applicable Lender or Applicable Administrative Agent, as the case may be, is able to purchase with the amount of the Other Currency received by it on the Business Day next following such receipt in accordance with its normal procedures and after deducting any premium and costs of exchange.

          (b) If, for the purpose of obtaining or enforcing judgment in any court in any jurisdiction, it becomes necessary to convert into a particular currency (the “Judgment Currency”) any amount due in the Agreed Currency then the conversion shall be made on the basis of the rate of exchange prevailing on the next Business Day following the date such judgment is given and in any event the Applicable Borrower shall be obligated to pay the Applicable Administrative Agent and the Applicable Lenders any deficiency in accordance with Section 2.23(c). For the foregoing purposes “rate of exchange” means the rate at which the Applicable Lender or Applicable Administrative Agent, as the case may be, in accordance with its normal banking procedures is able on the relevant date to purchase the Agreed Currency with the Judgment Currency after deducting any premium and costs of exchange.

          (c) To the fullest extent permitted by applicable law, if (i) any Lender or either Administrative Agent receives any payment or payments on account of the liability of a Borrower hereunder pursuant to any judgment or order in any Other Currency, and (ii) the

amount of the Agreed Currency which the Applicable Lender or Applicable Administrative Agent, as applicable, is able to purchase on the Business Day next following such receipt with the proceeds of such payment or payments in accordance with its normal procedures and after deducting any premiums and costs of exchange is less than the amount of the Agreed Currency due in respect of such liability immediately prior to such judgment or order, then such Borrower on demand shall, and such Borrower hereby agrees to, indemnify the Applicable Lender and the Applicable Administrative Agent from and against any loss, cost or expense arising out of or in connection with such deficiency.

          (d) To the fullest extent permitted by applicable law, the agreement of indemnity provided for in Section 2.23(c) shall constitute an obligation separate and independent from all other obligations contained in this Agreement, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by the Lenders or Administrative Agents or any of them from time to time, and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due hereunder or under any judgment or order.

     Section 2.24 Bankers’ Acceptances.

          (a) Subject to the terms and conditions of this Agreement, the Canadian Tranche Commitments may be utilized, upon the request of the Canadian Borrower, in addition to the Loans provided for by Section 2.01 and the issuance of Letters of Credit provided for by Section 2.05, for the acceptance by the Canadian Tranche Lenders of Bankers’ Acceptances issued by the Canadian Borrower, provided that (i) in no event shall the Equivalent Amount in US Dollars of the aggregate amount of all Bankers’ Acceptance Liabilities together with the Equivalent Amount in US Dollars of the aggregate principal amount of the other Loans (excluding BA Loans) and the aggregate amount of all Canadian LC Exposure exceed the aggregate amount of the Canadian Tranche Commitments of the Canadian Tranche Lenders, (ii) all Bankers’ Acceptances shall have maturities which are an integral multiple of thirty (30) days, and are not less than thirty (30) days or more than 180 days, from the Acceptance Date (and shall in no event mature on a date after the Revolving Commitment Termination Date), and (iii) in no event shall the amount of any Borrowing by way of Bankers’ Acceptance be less than C$1,000,000 and other than in multiples of C$100,000 for any amounts in excess thereof. Whenever the Canadian Borrower is required to furnish a notice to the Canadian Administrative Agent pursuant to the following additional provisions of this Section, it shall give a copy of such notice to the US Administrative Agent.

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

          (c) When the Canadian Borrower wishes to make a Borrowing by way of Bankers’ Acceptances, the Canadian Borrower shall give the Canadian Administrative Agent and the US Administrative Agent prior written notice with respect to the issuance of the Bankers’ Acceptances (such written notice a “Bankers’ Acceptance Request”) by not later than 1:00 p.m., Toronto time, two (2) Business Days’ prior to the Acceptance Date. Each Bankers’ Acceptance Request shall be irrevocable and binding on the Canadian Borrower. The Canadian

Borrower shall indemnify each Canadian Tranche Lender against any loss or expense incurred by such Lender as a result of any failure by the Canadian Borrower to fulfill or honor before the date specified as the Acceptance Date, the applicable conditions set forth in ARTICLE VI, if, as a result of such failure the requested Bankers’ Acceptance is not made on such date. Unless otherwise agreed among the Canadian Administrative Agent, the US Administrative Agent, and the Canadian Tranche Lenders, the aggregate amount of all Bankers’ Acceptances issued on any Acceptance Date hereunder shall be accepted pro rata by all Canadian Tranche Lenders relative to their respective Canadian Tranche Percentage, rounded, upwards or downwards, as the case may be, to the nearest C$100,000. Upon receipt of a Bankers’ Acceptance Request, the Canadian Administrative Agent shall advise each Canadian Tranche Lender of the contents thereof. Upon the acceptance of a Bankers’ Acceptance by a Canadian Tranche Lender, such Lender shall purchase such Bankers’ Acceptance from the Canadian Borrower and pay to the Canadian Administrative Agent, for the account of the Canadian Borrower, the amount of the BA Net Proceeds in respect of such Bankers’ Acceptance.

          (d) On each day during the period commencing with the issuance by the Canadian Borrower of any Bankers’ Acceptance and until such Bankers’ Acceptance Liability shall have been paid by the Canadian Borrower, the Canadian Tranche Commitment of each Accepting Lender that is able to extend credit by way of Bankers’ Acceptances shall be deemed to be utilized for all purposes of this Agreement in an amount equal to the Principal Amount of such Bankers’ Acceptance. The Canadian Tranche Commitment of any Canadian Tranche Lender providing a BA Loan rather than Bankers’ Acceptances shall be deemed utilized during this period in an amount equal to its Canadian Tranche Percentage of the total amount of Bankers’ Acceptances and BA Loans in each Bankers’ Acceptance Request.

          (e) The Canadian Borrower agrees to pay on the BA Maturity Date for each Bankers’ Acceptance, to the Canadian Administrative Agent for account of each Accepting Lender, an amount equal to the Bankers’ Acceptance Liability of the Canadian Borrower for such Bankers’ Acceptance. The Canadian Borrower hereby waives presentment for payment of Bankers’ Acceptances by each Accepting Lender and any defense to payment of amounts due to an Accepting Lender in respect of a Bankers’ Acceptance which might exist by reason of such Bankers’ Acceptance being held at maturity by the Accepting Lender which accepted it and agree not to claim from such Lenders any days of grace for the payment at maturity of Bankers’ Acceptances.

          (f) If the Canadian Borrower fails to notify the Canadian Administrative Agent in writing not later than 1:00 p.m., Toronto time, on the Business Day prior to any BA Maturity Date that the Canadian Borrower intends to pay with the Canadian Borrower’s own funds the Bankers’ Acceptance Liabilities due on such BA Maturity Date, or fails to make such payment, the Canadian Borrower shall be deemed, for all purposes to have given the Canadian Administrative Agent notice of a borrowing of a Canadian Prime Rate Loan pursuant to Section 2.03 for an amount equal to the Principal Amount of such Bankers’ Acceptance; provided that:

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

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

               (iii) each Canadian Tranche Lender which has made a maturing BA Loan (in accordance with Section 2.24(g) hereof) shall continue to extend credit to the Canadian Borrower (without further advance of funds to the Canadian Borrower) by way of a Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan (if in Canadian Dollars) in the Principal Amount equal to its Applicable Percentage of the total amount of credit requested to be extended by Bankers’ Acceptances when the BA Loan was made; and

               (iv) the Canadian Administrative Agent shall promptly and in any event within three (3) Business Days following the BA Maturity Date of such Bankers’ Acceptances, notify the Canadian Borrower in writing of the making of such Canadian Base Rate Loan pursuant to this Section 2.24(f).

          (g) If, in the sole judgment of a Canadian Tranche Lender, such Lender is unable, as a result of applicable law, customary market practice, or otherwise, to extend credit by way of Bankers’ Acceptance in accordance with this Agreement, such Lender shall give notice to such effect to the Canadian Administrative Agent and the Canadian Borrower prior to 11:00 a.m., Toronto time, on the date of the requested credit extension (which notice may, if so stated therein, remain in effect with respect to subsequent requests for extension of credit by way of Bankers’ Acceptance until revoked by notice to the Canadian Administrative Agent, the US Administrative Agent, and the Canadian Borrower) and shall make available to the Canadian Administrative Agent, in accordance with Section 2.01 hereof prior to 2:00 p.m., Toronto time, on the date of such requested credit extension, a Canadian Dollar Eurodollar Loan or, if such Lender is unable to make a Canadian Dollar Eurodollar Loan, a US Dollar Eurodollar Loan (each such Loan, a “BA Loan”) in the Principal Amount equal to such Lender’s Applicable Percentage of the total amount of credit requested to be extended by way of Bankers’ Acceptances. Such BA Loan shall have an Interest Period equal to the term of the Bankers’ Acceptances for which it is a substitute and shall bear interest throughout such Interest Period applicable to that BA Loan at a rate per annum equal to the Canadian Dollar LIBO Rate or the US Dollar LIBO Rate, as the case may be, plus the Eurodollar Margin. On the maturity date of the Bankers’ Acceptances issued concurrently with the advance of the BA Loan, the Canadian Borrower issuing such Bankers’ Acceptances shall, at its option, pay to each Canadian Tranche Lender which made a BA Loan, in satisfaction of the BA Loan, an amount equal to the Principal Amount of such BA Loan, together with accrued interest thereon, failing which such Principal Amount shall be continued as a Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan (if in Canadian Dollars); provided, however, all accrued interest on such BA Loan shall be paid in full on such maturity.

          (h) If a Canadian Tranche Lender determines in good faith, which determination shall be final, conclusive and binding upon the Canadian Borrower, and notifies the Canadian Borrower that, by reason of circumstances affecting the money market, (i) there is no market for Bankers’ Acceptances generally or of a requested duration, or (ii) the demand for Bankers’ Acceptances is insufficient to allow the sale or trading of the Bankers’ Acceptances created and purchased hereunder generally or in connection with a requested duration, then the right of the Canadian Borrower to request Bankers’ Acceptances of the affected duration from

that Canadian Tranche Lender shall be suspended until such Lender determines that the circumstances causing such suspension no longer exist and such Lender so notifies the Canadian Borrower, and any Bankers’ Acceptance Request for an affected duration which is outstanding shall be canceled and the Bankers’ Acceptances requested therein shall not be made and a Bankers’ Acceptance having the shortest duration available (or if none) a Canadian Base Rate Loan (if in US Dollars) or a Canadian Prime Rate Loan (if in Canadian Dollars) shall be made in its place.

          (i) It is the intention of the Canadian Administrative Agent, the Canadian Tranche Lenders, and the Canadian Borrower that, except to the extent a Canadian Tranche Lender advises otherwise, pursuant to the Depository Bills and Notes Act (“DBNA”), all Bankers’ Acceptances accepted by the Canadian Tranche Lenders under this Agreement shall be issued in the form of a “depository bill” (as defined in the DBNA), deposited with the Canadian Depository for Securities Ltd. and made payable to CDS & Co. In order to give effect to the foregoing, the Canadian Administrative Agent shall, subject to the approval of the Canadian Borrower and the Canadian Tranche Lenders, establish and notify the Canadian Borrower and the Canadian Tranche Lenders of any procedure, consistent with the terms of this Agreement and the requirements of the DBNA, as is reasonably necessary to accomplish such intention, including: (i) any instrument held by the Canadian Administrative Agent or a Canadian Tranche Lender for the purposes of Bankers’ Acceptances shall have marked prominently and legibly on its face and within its text, at or before the time of issue, the words “This is a depository bill subject to the Depository Bills and Notes Act (Canada)”; (ii) any reference to the authentication of the Bankers’ Acceptances will be removed; and (iii) any reference to “bearer” will be removed and no Bankers’ Acceptance shall be marked with any words prohibiting negotiation, transfer or assignment of it or of an interest in it.

          (j) (i) If any Event of Default shall have occurred and be continuing, on the Business Day that the Canadian Borrower receives notice from Canadian Tranche Lenders with BA Exposure representing greater than 66²/³% of the total BA Exposure or, if the maturity of the Loans has been accelerated, from the Canadian Administrative Agent, the US Administrative Agent, or the Majority Lenders, demanding the deposit of cash collateral pursuant to this paragraph, and (ii) on the Business Day that the Canadian Borrower receives notice from either the Canadian Administrative Agent acting alone, the US Administrative Agent acting alone, or the Majority Lenders demanding deposit of cash collateral pursuant to Section 2.08(b), the Canadian Borrower shall deposit in an account with the Canadian Administrative Agent, in the name of the Canadian Administrative Agent and for the benefit of the Canadian Tranche Lenders, an amount in cash equal to the BA Exposure of the Canadian Borrower as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default described in Section 7.01(g) or Section 7.01(h). Any such deposit shall be held by the Canadian Administrative Agent as collateral for the payment and performance of the obligations of the Canadian Borrower under this Agreement. The Canadian Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Canadian Administrative Agent and at the Canadian Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on

such investments shall accumulate in such account. Moneys in such account shall be applied by the Canadian Administrative Agent for the satisfaction of the obligations of the Canadian Borrower with respect to the BA Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Canadian Tranche Lenders with BA Exposure representing greater than 50% of the total BA Exposure), be applied to satisfy other obligations of the Canadian Borrower under this Agreement. If the Canadian Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Canadian Borrower within two (2) Business Days after all Events of Default have been cured or waived.

          (b) Within sixty (60) days after the close of each of the first three quarters of each of the US Borrower’s fiscal years a statement by a responsible officer of the US Borrower stating whether to the knowledge of the US Borrower an event has occurred during such period and is continuing which constitutes an Event of Default or a Default, and, if so, stating the facts with respect thereto.

          (c) Within one hundred twenty (120) days after the close of each of the US Borrower’s fiscal years a statement by a responsible officer of the US Borrower stating whether to the knowledge of the US Borrower an event has occurred during such period and is continuing which constitutes an Event of Default or a Default, and, if so, stating the facts with respect thereto.

     Section 4.04 Use of Proceeds.

     Section 9.02 Waivers; Amendments.

          (a) No failure or delay by the US Administrative Agent, the Canadian Administrative Agent, any Issuing Bank or any Lender in exercising any right or power hereunder 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 US Administrative Agent, the Canadian Administrative Agent, any Issuing Bank, and the Lenders hereunder 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 consent to any departure by the US Borrower or the Canadian Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, to the fullest extent permitted by applicable law, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Event of Default, regardless of whether the US Administrative Agent, the Canadian Administrative Agent, any Lender or any Issuing Bank may have had notice or knowledge of such Event of Default at the time.

          (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 Majority Lenders or by the Borrowers and the Administrative Agents with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce any Principal Amount or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment of any Principal Amount or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) extend the expiry date of any Letter of Credit beyond the then scheduled Revolving Commitment Termination Date without the written consent of each Lender,

(v) change Section 2.13(a) or Section 2.13(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) change Section 6.01, without the consent of each Lender, (vii) release the US Borrower, in its capacity as Guarantor, from the Guaranty or limit its liability in respect of the Guaranty without the written consent of each Canadian Tranche Lender, or (viii) change any of the provisions of this Section or the definition of “Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the US Administrative Agent, the Canadian Administrative Agent or any Issuing Bank hereunder without the prior written consent of the US Administrative Agent, the Canadian Administrative Agent, or such Issuing Bank.

     Section 9.03 Expenses; Indemnity; Damage Waiver.

Notwithstanding anything to the contrary, the Borrowers shall not have any obligation to pay the fees or expenses of any Lender or any Administrative Agent in connection with any assignment of, or the grant of any participation in, any rights of a Lender under or in connection with this Agreement; provided that the provisions of this sentence shall not apply to any Lender substituted for a Defaulting Lender pursuant to Section 9.13 (b) and (c).

          (b) The Borrowers shall indemnify each Administrative Agent, each Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee (on a solicitor and his own client basis), incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the

consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by any Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of hazardous materials on or from any property owned or operated by any Borrower or any Subsidiary, or any environmental liability related in any way to any Borrower or any Subsidiary, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses either (i) did not result directly or indirectly from the action or inaction of any Borrower or any Subsidiary, or (ii) resulted from the gross negligence, unlawful conduct or willful misconduct of such Indemnitee.

          (c) To the extent that the Borrowers fail to pay any amount required to be paid by them to any Administrative Agent, or any Issuing Bank under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to such Administrative Agent or such Issuing Bank, as the case may be, such Lender’s Applicable Percentage (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 Administrative Agent, or such Issuing Bank in its capacity as such.

          (d) All amounts due under this Section shall be payable promptly after written demand therefor together with a copy of the invoice(s) or other documentation setting forth in reasonable detail the amount demanded and the matter(s) to which it relates.

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

          (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its US Tranche Commitment or Canadian Tranche Commitment, as the case may be, or, in the case of a Dual Lender, both and the Loans at the time

owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

                    (A) the US Borrower, provided that no consent of the US Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender or, if an Event of Default under Section 7.01(a), (b), (g), (h) or (i) has occurred and is continuing, any other assignee; and

                    (B) the US Administrative Agent, provided that no consent of the US Administrative Agent shall be required for an assignment of any Revolving Commitment to an assignee that is a Lender with a Commitment immediately prior to giving effect to such assignment or an Affiliate of a Lender.

               (ii) Assignments shall be subject to the following additional conditions:

                    (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans of any Class, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agents) shall not be less than $10,000,000 unless each of the US Borrower and the US Administrative Agent otherwise consent, provided that no such consent of the US Borrower shall be required if an Event of Default under Section 7.01(a), (b), (g), (h) or (i) has occurred and is continuing;

                    (B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement and, unless each of the US Borrower and the US Administrative Agent otherwise consent, shall result in the assigning Lender having no less than $10,000,000 in Commitments and Loans after giving effect to such assignment;

                    (C) the parties to each assignment shall execute and deliver to the US Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500;

                    (G) after giving effect to the assignment to it, each assignee of an assigning Canadian Tranche Lender shall be a Canadian Tranche Lender.

               (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(v) of this Section, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.14, Section 2.16, Section 2.22 and Section 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 9.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section.

               (iv) The US Administrative Agent and the Canadian Administrative Agent, acting for this purpose as an agent of the Applicable Borrowers, shall maintain at one of its offices in New York City and Toronto, Canada, respectively, a copy of each Assignment and Assumption 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 and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be prima facie evidence of the existence and amounts of the obligations recorded therein, and the Borrowers, the Administrative Agents, each Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary.

          (c) (i) Any Lender may, without the consent of any Borrower, either Administrative Agent or any Issuing Bank, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such

obligations and (C) the Borrowers, the Administrative Agents, each Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrowers agree that each Participant shall be entitled to the benefits of Section 2.14, Section 2.16 and Section 2.22 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. Notwithstanding anything to the contrary, unless otherwise contractually agreed, no Participant shall be entitled to the benefits of Section 9.08 as though it were a Lender,.

               (ii) A Participant shall not be entitled to receive any greater payment under Section 2.14 or Section 2.16 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrowers’ prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.16 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 2.16(e) and Section 2.16(g) as though it were a Lender.

          (d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank in accordance with Regulation A of the Board of Governors of the Federal Reserve System, and to a trustee for the benefit of holders of debt securities issued by such Lender, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

The provisions of Section 2.14, Section 2.16, Section 2.22, Section 2.23, Section 9.03, this Section 9.05, and ARTICLE VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or

termination of the Letters of Credit and the Commitments or the termination of this Agreement or any other provision hereof.

     Section 9.06 Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the US Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agents and when the US Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

     Section 9.07 Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

     Section 9.08 Right of Setoff. If (a) an Event of Default shall have occurred and be continuing, and (b) the principal of the Loans has been accelerated each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender to or for the credit or the account of any Borrower against any of and all the obligations of the Borrowers now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

          (e) The Guarantor waives presentment to, demand of payment from and protest to the Canadian Borrower of any of the Guaranteed Obligations, and also waives notice

          (f) To the fullest extent permitted by applicable law, the obligations of the Guarantor hereunder are absolute and unconditional and shall not be subject to any reduction, limitation, impairment or termination for any reason (other than the payment in full in cash of all the Guaranteed Obligations), including any claim of waiver, release, surrender, alteration or compromise of any of the Guaranteed Obligations, and shall not be subject to any defense (other than a defense of payment or performance), set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or any Note, Letter of Credit, other Loan Document or otherwise.

At all times while the Combined Credit Exposure equals or exceeds 50% of the availability under this Agreement, a Utilization Fee shall be applicable as more specifically set forth in Section 2.04(b).

     Ratings in the above pricing grid relate to US Borrower’s senior unsecured non-credit enhanced publicly held indebtedness (the “Index Debt”). For purposes of the foregoing, (i) if either Moody’s or S&P shall not have in effect a rating for the Index Debt (other than by reason of the circumstances referred to in the last sentence of this definition), then such rating agency shall be deemed to have established a rating in Category 6; (ii) if the ratings established or deemed to have been established by Moody’s and S&P for the Index Debt shall fall within different Categories, each rate specified above (the “Applicable Rate”) shall be based on the higher of the two ratings unless one of the ratings is two or more Categories lower than the other, in which case the Applicable Rate shall be determined by reference to the Category next above that of the lower of the two ratings; and (iii) if the ratings established or deemed to have been established by Moody’s and S&P for the Index Debt shall be changed (other than as a result of a change in the rating system of Moody’s or S&P), such change shall be effective as of the date on which it is first announced by the applicable rating agency. Each change in the Applicable Rate shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the US Borrower, the Canadian Borrower and the Lenders shall negotiate in good faith to amend this definition to reflect such changed rating system or the
