All payments made by any Loan Party under any Loan Document will be made free and clear of, and without deduction or withholding for, any Taxes, except as otherwise required by applicable law, and in the event any deduction or withholding of Taxes is required, the applicable Loan Party shall make the requisite deduction or withholding, promptly pay over to the applicable Governmental Authority the amount of Tax deducted or withheld, and furnish to Agent as promptly as possible after the date the payment of any such Tax is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by the Loan Parties.

(q)The Credit Agreement is hereby amended by inserting the following sections after Section 17.15:

17.16 - Judgment Currency. If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due hereunder or any other Loan Document in one currency into another currency, the rate of exchange used shall be that at which in accordance with normal banking procedures Agent could purchase the first currency with such other currency on the Business Day preceding that on which final judgment is given. The obligation of each Loan Party in respect of any such sum due from it to Agent or any Lender hereunder or under the other Loan Documents shall, notwithstanding any judgment in a currency (the "Judgment Currency") other than that in which such sum is denominated in accordance with the applicable provisions of this Agreement (the "Agreement Currency"), be discharged only to the extent that on the Business Day following receipt by Agent or such Lender, as the case may be, of any sum adjudged to be so due in the Judgment Currency, Agent or such Lender, as the case may be, may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the sum originally due to Agent or any Lender from any Loan Party in the Agreement Currency, such Loan Party agrees, as a separate obligation and notwithstanding any such judgment, to indemnify Agent or such Lender, as the case may be, against such loss. If the amount of the Agreement Currency so purchased is greater than the sum originally due to Agent or any Lender in such currency, Agent or such Lender, as the case may be, agrees to return the amount of any excess to such Loan Party (or to any other Person who may be entitled thereto under applicable law).

-14-

DB1/ 124616894.9

17.17 - Interest Act (Canada). For the purposes of this Agreement with respect to the Canadian Guarantors, whenever interest to be paid hereunder is to be calculated on the basis of 360 days or any other period of time that is less than a calendar year, the yearly rate of interest to which the rate determined pursuant to such calculation is equivalent is the rate so determined multiplied by the actual number of days in the calendar year in which the same is to be ascertained and divided by 360 or such other number of days in such period, as the case may be.

17.18 – Maximum Rate of Interest. Notwithstanding anything contained herein to the contrary, the Loan Parties will not be obliged to make any payment of interest or other amounts payable to the Lenders hereunder in excess of the amount or rate that would be permitted by applicable law or would result in the receipt by the Lenders of interest at a criminal rate (as such terms are construed under the Criminal Code (Canada)). If the making of any payment by any Loan Party would result in a payment being made that is in excess of such amount or rate, the Agent will determine the payment or payments that are to be reduced or refunded, as the case may be, so that such result does not occur.

2.Amendments to Guaranty and Security Agreement. In reliance on the representations and warranties of the Loan Parties set forth in Section 5 below, and subject to the satisfaction of the conditions to effectiveness set forth in Section 4 below, the Credit Agreement (but not the Schedules and Exhibits attached thereto) shall be amended as set forth below in this Section 2 (such amendments, together with the Credit Agreement Amendments, collectively, the “Amendments”):
