(a)   At such time as the Canadian Facility Revolving Credit Loans, any Reimbursement Obligations with respect to Canadian Facility Letters of Credit issued to, or for the account of, a Canadian Borrower, and all other Obligations then due and owing, shall have been paid in full in cash, no Canadian Facility Letter of Credit issued to, or for the account of, a Canadian Borrower shall be outstanding (except for Canadian Facility Letters of Credit issued to, or for the account of, a Canadian Borrower that have been cash collateralized, or otherwise provided for in a manner reasonably satisfactory to the applicable Canadian Facility Issuing Lender) and the Canadian Facility Commitments shall have terminated, all Security Collateral shall be automatically released from the Liens created hereby, and this Agreement and all obligations (other than those expressly stated to survive such termination) of the Collateral Agent, the Administrative Agent and each Granting Party hereunder shall terminate, all without delivery of any instrument or performance of any act by any party, and all rights to the Security Collateral shall revert to the Granting Parties. At the request and sole expense of any Granting Party following any such termination, the Collateral Agent and the Administrative Agent shall deliver to such Granting Party (subject to Subsection 7.2 , without recourse and without representation or warranty) any Security Collateral held by the Collateral Agent hereunder, and execute, acknowledge and deliver to such Granting Party such releases, instruments or other documents (including PPSA financing change statements and discharges), and do or cause to be done all other acts, as any Granting Party shall reasonably request to evidence such termination.
