Section 4. Representations and Warranties. Each Borrower represents and warrants that (i) the representations and warranties of such Borrower contained in Section 4.01 of the Amended Credit Agreement (with each reference therein to “this Agreement”, “hereunder” and words of like import referring to the Credit Agreement being deemed to be a reference to the Amended Credit Agreement and each reference therein to “Loan Document” and words of like import being deemed to be a reference that includes this Amendment and the Amended Credit Agreement) are true and correct on and as of the Amendment Date as though made on and as of the Amendment Date (other than, as to any such representation or warranty that by its terms refers to a specific date other than the Amendment Date, in which case, such representation and warranty shall be true and correct as of such specific date); and (ii) no event has occurred and is continuing, or would result from the execution, delivery or performance by such Borrower of this Amendment or the performance by such Borrower of the Amended Credit Agreement that constitutes an Event of Default or an Unmatured Default with respect to such Borrower.

Except as expressly set forth herein, each of the Credit Agreement and the other Loan Documents is and shall continue to be in full force and effect and is hereby in all respects ratified and confirmed.

respect to advising the Administrative Agent as to their rights and responsibilities under this Amendment. Each Borrower further agrees to pay on demand all reasonable out-of-pocket costs and expenses, if any (including, without limitation, reasonable counsel fees and expenses of counsel), incurred by the Administrative Agent and the Lenders in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Amendment, the Amended Credit Agreement and the other documents to be delivered hereunder, including, without limitation, counsel fees and expenses in connection with the enforcement of rights under this Section.

Section 7. Counterparts. This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.
