To that end, but only in the event and to the extent that the Guarantor’s respective obligations hereunder or any payment made pursuant thereto would, but for the operation of the foregoing proviso, be subject to avoidance or recovery under Applicable Insolvency Laws, the amount of the Guarantor’s respective obligations hereunder shall be limited to the largest amount which, after giving effect thereto, would not, under Applicable Insolvency Laws, render the Guarantor’s respective obligations hereunder unenforceable or avoidable or subject to recovery under Applicable Insolvency Laws. To the extent any payment actually made hereunder exceeds the limitation contained in this

8

Section 20, then the amount of such excess shall, from and after the time of payment by the Guarantors (or any of them), be reimbursed by the Lenders upon demand by such Guarantors. The foregoing proviso is intended solely to preserve the rights of the US Agent, the Canadian Agent and the Lenders hereunder against the Guarantors to the maximum extent permitted by Applicable Insolvency Laws and neither the US Borrowers nor any one of them, nor any Guarantor nor any other Person shall have any right or claim under this Section 20 that would not otherwise be available under Applicable Insolvency Laws.
