(2) If, with respect to the Lender, (i) any change in any law, rule, regulation, judgment or order of general application, or any change in the interpretation or application of such law, rule, regulation, judgment or order, occurring or becoming effective after this date, or (ii) compliance by the Lender with any direction, request or requirement (whether or not having the force of law) of any Governmental Entity made or becoming effective after the date, has the effect of causing any loss to the Lender or reducing the Lender's rate of return by (w) increasing the cost to the Lender of performing its obligations under this Agreement or in respect of any Accommodations Outstanding (including the costs of maintaining any capital, reserve or special deposit requirements but other than a reduction resulting from a higher rate or from a change in the calculation of income or capital tax relating to the Lender's income or capital in general), (x) requiring the Lender to maintain or allocate any capital or additional capital or affecting its allocation of capital in respect of its obligations under this Agreement or in respect of any Accommodations Outstanding, (y) reducing any amount payable to the Lender under this Agreement or in respect of any Accommodations Outstanding by any material amount, (z) causing the Lender to make any payment or to forego any return on, or calculated by reference to, any amount received or receivable by the Lender under this Agreement or in respect of any Accommodations Outstanding, then the Lender may give notice to the Borrower specifying the nature of the event giving rise to the loss and the Borrower may either (iii) on demand, pay such amounts as the Lender specifies is necessary to compensate it for any such loss, or (iv) provided no loss has yet been suffered by the Lender or the Borrower has paid the compensating amount to the Lender, repay the Accommodations Outstanding and terminate the Lender's Commitments.

(3) The Borrower shall pay to the Lender on demand any amounts required to compensate the Lender for any loss suffered or incurred by it as a result of (i) any payment being made in respect of a BA Instrument, Documentary Credit or Advance, other than on the maturity or expiration or on the last day of an Eurodollar Interest Period applicable to it, (ii) the failure of the Borrower to give any notice in the manner and at the times required by this Agreement, (iii) the failure of the Borrower to effect an Accommodation in the manner and at the time specified in any Accommodation Notice, or (iv) the failure of the Borrower to make a payment or a mandatory repayment in the manner and at the time specified in this Agreement.

(4) The provisions of this Section 11.6 shall survive the termination of this Agreement and the repayment of all Accommodations Outstanding. The Borrower acknowledges that neither its obligation to indemnify nor any actual indemnification by it of the Lender or any other Indemnified Person in respect of such Person's losses for the legal fees and expenses shall in any way affect the confidentiality or privilege relating to any information communicated by such Person to its counsel. SECTION 11.7 TAXES AND OTHER TAXES. (1) All payments to the Lender by the Borrower under any of the Loan Documents shall be made free and clear of and without deduction or withholding for any and all taxes, levies, imposts, deductions, charges or withholdings and all related liabilities (all such taxes, levies, imposts, deductions, charges, withholdings and liabilities being referred to as "TAXES") imposed by Canada or the United States of America (or any political subdivision or taxing authority of it), unless such Taxes are required by applicable law to be deducted or withheld. If the Borrower shall be required by applicable law to deduct or withhold any such Taxes from or in respect of any amount payable under any of the Loan Documents except, as provided in the next sentence, (i) the amount payable shall be increased (and for greater certainty, in the case of interest, the amount of interest shall be increased) as may be necessary so that after making all required deductions or withholdings (including deductions or withholdings applicable to any additional amounts paid under this Section 11.7(1), the Lender receives an amount equal to the amount they would have received if no such deduction or withholding had been made, (ii) the Borrower shall make such deductions <Page> 66 or withholdings, and (iii) the Borrower shall immediately pay the full amount deducted or withheld to the relevant Governmental Entity in accordance with applicable law. (2) The Borrower agrees to immediately pay any present or future stamp or documentary taxes or any other excise or property taxes, charges, financial institutions duties, debits taxes or similar levies (all such taxes, charges, duties and levies being referred to as "OTHER TAXES") which arise from any payment made by the Borrower under any of the Loan Documents or from the execution, delivery or registration of, or otherwise with respect to, any of the Loan Documents. (3) The Borrower shall indemnify the Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable by the Borrower under this Section 11.7 paid by the Lender and any liability (including penalties, interest and expenses) arising from or with respect to such Taxes or Other Taxes, whether or not they were correctly or legally asserted, excluding taxes imposed on the Lender's net income, capital taxes or receipts and franchise taxes. The Borrower will not be required to indemnify the Lender for any Taxes or Other Taxes imposed by reason of the Lender being connected with Canada otherwise than merely by lending money to the Borrower pursuant to this Agreement. Payment under this indemnification shall be made within 30 days from the date the Lender make written demand for it. A certificate as to the amount of such Taxes or Other Taxes submitted to the Borrower by the Lender shall be conclusive evidence, absent manifest error, of the amount due from the Borrower to Lender. (4) The Borrower shall furnish, at the request of the Lender, the original or a certified copy of a receipt evidencing payment of Taxes or Other Taxes made by the Borrower within 30 days after the date of any payment of Taxes or Other Taxes. (5) If the Lender is, in its sole opinion, entitled to claim a refund or able to apply for or otherwise take advantage of any tax credit, tax deduction or similar benefit by reason of any withholding or deduction made by the Borrower in respect of a payment made by it under this Agreement, which payment shall have been increased pursuant to Section 11.7(1), then the Lender will use reasonable effort to obtain the refund, credit, deduction or benefit and upon credit or receipt of it will pay to the Borrower, the amount (if any) not exceeding the increased amount paid by the Borrower, as equals the net after-tax value to the Lender of that part of the refund, credit, deduction or benefit as it considers is allocatable to such withholding or deduction having regard to all of its dealings giving rise to similar credits, deductions or benefits in <Page> 67 relation to the same tax period and to the cost of obtaining the same. Nothing contained in this Section 11.7(5) shall interfere with the right of the Lender to arrange its tax affairs in whatever manner it deems fit and in particular, the Lender shall be under no obligation to claim relief from its corporate profits or similar tax liability in respect of any deduction or withholding in priority to any other relief, claims, credits or deductions available to it and the Lender shall not be obligated to disclose to the Borrower any information regarding its tax affairs, tax computations or otherwise. (6) The provisions of this Section 11.7 shall survive the termination of the Agreement and the repayment of all Accommodations Outstanding. SECTION 11.8 SUCCESSORS AND ASSIGNS. (1) This Agreement shall become effective when executed by the Borrower and the Lender and after that time shall be binding upon and enure to the benefit of the Borrower and the Lender and their respective successors and permitted assigns. (2) The Borrower shall not have the right to assign its rights or obligations under this Agreement or any interest in this Agreement without the prior consent of the Lender, which consent may be arbitrarily withheld. (3) At any time prior to the occurrence of an Event of Default, the Lender may with the prior written consent of the Borrower (which consent, in the case of the Borrower, is not to be unreasonably withheld), assign all or any part of its interest in the Loan Facilities to one or more Persons (each an "ASSIGNEE") provided that such assignment is not made to a Person the identity of which would have the effect of imposing additional obligations upon the Borrower as a result of the application of Section 11.7 hereof. At any time after the occurrence of an Event of Default, the Lender may assign all or any part of its interest in the Loan Facilities to an Assignee without any requirement for notice to or consent of the Borrower or any other Person. In the case of an assignment, the Assignee shall have the same rights and benefits and be subject to the same limitations under the Loan Documents as it would have if it was a Lender. SECTION 11.9 RIGHT OF SET-OFF. Following the occurrence, and during the continuance of an Event of Default, the Lender is authorized at any time and from time to time, to the fullest extent permitted by law (including general principles of common-law), to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by it to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower under <Page> 68 any of the Loan Documents. If an obligation is unascertained, the Lender may, in good faith, estimate the obligation and exercise its right of set-off in respect of the estimate, subject to providing the Borrower with an accounting when the obligation is finally determined. The Lender shall promptly notify the Borrower after any set-off and application is made by it, provided that the failure to give notice shall not affect the validity of the set-off and application. The rights of the Lender under this Section 11.9 are in addition to any other rights and remedies (including all other rights of set-off) which the Lender may have. SECTION 11.10 JUDGMENT CURRENCY. (1) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due to the Lender in any currency (the "ORIGINAL CURRENCY") into another currency (the "OTHER CURRENCY"), the parties agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be that at which, in accordance with normal banking procedures, the Lender could purchase the Original Currency with the Other Currency on the Business Day preceding the day on which final judgment is given or, if permitted by applicable law, on the day on which the judgment is paid or satisfied. (2) The obligations of the Borrower in respect of any sum due in the Original Currency from it to the Lender under any of the Loan Documents shall, notwithstanding any judgment in any Other Currency, be discharged only to the extent that on the Business Day following receipt by the Lender of any sum adjudged to be so due in the Other Currency, the Lender may, in accordance with normal banking procedures, purchase the Original Currency with such Other Currency. If the amount of the Original Currency so purchased is less than the sum originally due to the Lender in the Original Currency, the Borrower agrees, as a separate obligation and notwithstanding the judgment, to indemnify the Lender, against any loss, and, if the amount of the Original Currency so purchased exceeds the sum originally due to the Lender in the Original Currency, the Lender shall remit such excess to the Borrower. SECTION 11.11 INTEREST ON AMOUNTS. Except as may be expressly provided otherwise in this Agreement, all amounts owed by the Borrower to the Lender which are not paid when due (whether at stated maturity, on demand, by acceleration or otherwise) shall bear interest (both before and after default and judgment), from the date on which such amount is due until such amount is paid in full, payable on demand, at a rate per annum equal at all times to (i) in the case of an amount payable in U.S. Dollars, the sum of the Base Rate (Canada) in effect from time to time, the Applicable Margin <Page> 69 and 2%, and (ii) in the case of an amount payable in Canadian Dollars, the sum of the Canadian Prime Rate in effect from time to time, the Applicable Margin and 2%. SECTION 11.12 GOVERNING LAW. This Agreement shall be governed by and interpreted and enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein. SECTION 11.13 COUNTERPARTS. This Agreement may be executed in any number of counterparts and all of such counterparts taken together shall be deemed to constitute one and the same instrument. SECTION 11.14 FACSIMILE SIGNATURES. This Agreement may be executed by facsimile signature, in which case the party executing by facsimile shall forward an original counterpart thereof to the other party but failure to so deliver shall not invalidate this Agreement. SECTION 11.15 CONSENT TO JURISDICTION. The Borrower hereby irrevocably submits to the jurisdiction of any Ontario court sitting in Toronto in any action or proceeding arising out of or relating to the Loan Documents and hereby irrevocably agrees that all claims in respect of any such action or proceeding may be heard and determined in such Ontario court. The Borrower and each Restricted Subsidiary hereby irrevocably waive, to the fullest extent they may effectively do so, the defense of an inconvenient forum to the maintenance of such action or proceeding. The Borrower and each Restricted Subsidiary agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section 11.15 shall affect the right of the Lender to bring any action or proceeding against the Borrower or each Restricted Subsidiary or their property in the courts of other jurisdictions. <Page> IN WITNESS WHEREOF the parties have executed this Agreement.
