13.2 Effect of Event of Default. If any Event of Default described in Section 13.1.3 shall occur in respect of the Company, the Commitments shall immediately terminate and the Loans and all other Obligations hereunder shall become immediately due and payable and the Company shall become immediately obligated to Cash Collateralize all Letters of Credit, all without presentment, demand, protest or notice of any kind; and, if any other Event of Default
shall occur and be continuing, the Administrative Agent may (and, upon the written request of the Required Lenders shall) declare the Commitments to be terminated in whole or in part and/or declare all or any part of the Loans and all other Obligations hereunder to be due and payable and/or demand that the Company immediately Cash Collateralize all or any Letters of Credit, whereupon the Commitments shall immediately terminate (or be reduced, as applicable) and/or the Loans and other Obligations hereunder shall become immediately due and payable (in whole or in part, as applicable) and/or the Company shall immediately become obligated to Cash Collateralize the Letters of Credit (all or any, as applicable), all without presentment, demand, protest or notice of any kind. The Administrative Agent shall promptly advise the Company of any such declaration, but failure to do so shall not impair the effect of such declaration. Any cash collateral delivered hereunder shall be held by the Administrative Agent (without liability for interest thereon) and applied to the Obligations arising in connection with any drawing under a Letter of Credit. After the expiration or termination of all Letters of Credit, such cash collateral shall be applied by the Administrative Agent to any remaining Obligations hereunder and any excess shall be delivered to the Company or as a court of competent jurisdiction may elect.
