10.10 Collateral and Guarantee Matters.
The Lenders and the L/C Issuer irrevocably authorize the Administrative Agent, at its option and in its discretion, and the Administrative Agent agrees:
(a) to release any Lien on any property granted to or held by the Administrative Agent under any Loan Document (i) upon termination of the Aggregate Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit, (ii) that is sold as part of or in connection with any sale permitted hereunder or under any other Loan Document, or (iii) subject to Section 11.01, if approved, authorized or ratified in writing by the Required Lenders; and
(b) to release any Guarantor from its obligations under the Guarantee if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.
So long as the Borrower shall have provided the Administrative Agent such certifications or documents as the Administrative Agent shall reasonably request, the Administrative Agent shall take such actions as are necessary to evidence each release described in this Section 10.10 in accordance with the relevant provisions of the Collateral Documents. Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agents authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guarantee pursuant to this Section 10.10.
