Delivery of an executed counterpart of this Amendment by telefacsimile or other electronic method of transmission shall be equally as effective as delivery of an original executed counterpart of this Amendment. Any party delivering an executed counterpart of this Amendment by telefacsimile or other electronic method of transmission also shall deliver an original executed counterpart of this Amendment but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Amendment.

Neither the execution, delivery, performance or effectiveness of this Amendment nor the modification of the Credit Agreement effected pursuant hereto: (i) impairs the validity, effectiveness or priority of the Liens granted pursuant to any Loan Document, and such Liens continue unimpaired with the same priority to secure repayment of all Secured Obligations, whether heretofore or hereafter incurred; or (ii) requires that any new filings be made or other action be taken to perfect or to maintain the perfection of such Liens.

Section 3.7 Arranger. The Amendment No. 1 Arranger, in such capacity, shall benefit from the same protections, immunities, indemnities and exclusions from liability as are conferred in favor of the Joint Lead Arrangers in the Credit Agreement, which shall apply mutatis mutandis.
