following the effectiveness of this Amendment) of all Advances then outstanding

Agent not later than 12:00 P.M. (New York time) on the Amendment Effective Date.
The Administrative Agent shall distribute on the Amendment Effective Date the
proceeds of such amount to each of the Selling Lenders entitled to receive such
payments at its Applicable Lending Office. If in connection with the
transactions described in this Section 2 any Lender shall incur any losses,
costs or expenses of the type described in Section 9.04(c) of the Credit
Agreement, then the Borrower shall, upon demand by such Lender (with a copy of

Date, before and after giving effect to this Amendment, as though made on and as

terms, refers to a specific date other than the Amendment Effective Date, in
which case as of such specific date).

(c) No event shall have occurred and be continuing, or shall result from the

remedy of any Lender or the Administrative Agent under any of the Loan
Documents, nor constitute a waiver of any provision of any of the Loan
Documents.
