Each Lender party hereto (a) consents to a release by the Administrative Agent under the Guarantee and Collateral Agreement of any and all Liens on the Capital Stock of the Borrower thereunder, effective concurrently with the HVHC Transaction, and (b) agrees that any such release shall not constitute an Event of Default under Section 8(i) of the Credit Agreement.
