WHEREAS, pursuant to the terms and subject to the conditions contained in the Agreement, the Lenders have extended, and have agreed to extend, credit to the Borrowers; and WHEREAS, the Borrower has requested that Section 4.15 of the Agreement be modified in the manner provided for in this amendment, and the Lenders are willing to amend the Agreement as requested by the Borrower, subject to the terms and conditions hereinafter set forth. NOW THEREFORE, in consideration of the mutual agreements herein contained and other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto agree as follows: SECTION 1. Amendment. Section 4.15 of the Agreement is hereby amended and restated in its entirety as set forth below: "SECTION 4.15. Employee Benefit Plans. (a) Each Borrower and their respective ERISA Affiliates is in compliance in all material respects with the applicable provisions of ERISA and the Code and the regulations and published interpretations thereunder. No Reportable Event has occurred in respect of any Plan of either Borrower or any ERISA Affiliate. The present value of all benefit liabilities of all underfunded Plans (based on those assumptions used to fund each such Plan) did not, as of the last annual valuation dates applicable thereto, exceed the value of the assets of the Plans by an amount that could reasonably be expected to result in a Material Adverse Effect. No Plan of either Borrower or any ERISA Affiliate is reasonably likely to have an unfunded benefit liability that could result in a Material Adverse Effect. Neither Borrower nor any ERISA Affiliate has incurred any Withdrawal Liability that could result in a Material Adverse Effect. Neither Borrower nor any ERISA Affiliate has received any notification that any Multiemployer Plan is in reorganization or has been terminated within the meaning of Title IV of ERISA and no Multiemployer Plan is reasonably expected to be in reorganization or to be terminated where such reorganization or termination has resulted or could reasonably be expected to result, through increases in the contributions required to be made to such Plan or otherwise, in a Material Adverse Effect. (b) The Canadian Pension Plans are duly registered under the ITA and any other applicable laws which require registration, have been administered in all material respects in accordance with the ITA and such other applicable laws and no event has occurred which could reasonably be expected to cause the loss of such registered status. All material obligations of Canco and each of its Subsidiaries required to be performed by Canco or its Subsidiaries in connection with the Canadian Pension Plans and the funding agreements therefor have been performed on a timely basis. As of the Closing Date, there are no outstanding disputes concerning the assets of the Canadian Pension Plans or the Canadian Benefit Plans. No promises of benefit improvements under the Canadian Pension Plans or the Canadian Benefit Plans have been made except where such improvement could not reasonably be expected to have a Material Adverse Effect. All contributions or premiums required to be made or paid by Canco and each of its Subsidiaries to the Canadian Pension Plans or the Canadian Benefit Plans have been made on a timely basis in accordance with the terms of such plans and all applicable laws. There have been no improper withdrawals or applications of the assets of the Canadian Pension Plans or the Canadian Benefit Plans. None of the Canadian Pension Plans or the Canadian Benefit Plans has any unfunded actuarial liabilities or solvency deficiencies (within the meaning of the Quebec Supplemental Pension Plans Act) in an aggregate amount that could reasonably be expected to result in a Material Adverse Effect." SECTION 2. Representations and Warranties. To induce the other ------------------------------ parties hereto to enter into this Amendment, each Borrower represents and warrants to each of the Lenders, the Administrative Agent, the Agents, the Facing Agent, the Collateral Agent and the Canadian Administrative Agent that, after giving effect to this Amendment, (a) the representations and warranties set forth in Article IV of the Agreement are true and correct in all material respects on and as of the date hereof, except to the extent such representations and warranties expressly relate to an earlier date, and (b) no Default or Event of Default has occurred and is continuing. SECTION 3. Conditions to Effectiveness. This Amendment shall become --------------------------- effective on the date on which the Agents shall have received counterparts of this Amendment that, when taken together, bear the Borrowers and the Required Lenders signature.

Nothing herein shall be deemed to entitle the Borrowers or the Guarantors to a consent to, or a waiver, amendment, modification or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Agreement or any other Loan Document in similar or different circumstances. SECTION 5. Counterparts. This Amendment may be executed in any ------------ number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts constitute but one and the same instrument. Delivery of any executed counterpart of a signature page of this Amendment by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. SECTION 6. APPLICABLE LAW. THIS AMENDMENT SHALL BE GOVERNED BY, AND -------------- CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. SECTION 7. Headings.
