4.1    Representations and Warranties.  After giving effect to this Amendment, each of the representations and warranties made by or on behalf of the Credit Parties to Agent and the Lenders in all of the Loan Documents was true and correct in all material respects when made and is true and correct in all material respects on and as of the date of this Amendment with the same full force and effect as if each of such representations and warranties had been made by such Person on the date hereof and in this Amendment, except to the extent that such representation and warranty expressly relates to an earlier date and except for changes therein expressly permitted or expressly contemplated by the Credit Agreement, and except as consented to or waived.

(ii)    the Credit Agreement and indebtedness evidenced and secured thereby; or
(iii)    any other agreement or transaction between any Credit Party and any Releasee entered into in connection with the Credit Agreement.

If any Credit Party or any of its successors, assigns or designees violates the foregoing covenant, such Credit Party and its successors, assigns and designees, jointly and severally agree to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by any Releasee as a result of such violation.
(c)    Does hereby expressly acknowledge and agree that the covenants and agreements of Agent and the Lenders contained in this Amendment shall not be construed as an admission of any wrongdoing, liability or culpability on the part of Agent or any Lender or as any admission by Agent or any Lender of the existence of claims by any Credit Party against Agent, the Lenders or any other Releasee.  Each Credit Party, Agent and the Lenders acknowledge and agree that the value to the Credit Parties of the covenants, consents and agreements on the part of Agent and the Lenders contained in this Amendment substantially and materially exceed any and all value of any kind or nature whatsoever of any claims or other liabilities waived or released by the Credit Parties.
(d)    Notwithstanding anything contained in this Amendment, the general release set forth in this Amendment shall not extend to and shall not include any duties or obligations of Agent or the Lenders in the Credit Agreement as modified by this Amendment or in any of the Loan Documents.
7.7    Entire Agreement.

7.8    GOVERNING LAW.  THE LAWS OF THE STATE OF NEW YORK SHALL GOVERN ALL MATTERS ARISING OUT OF, IN CONNECTION WITH OR RELATING TO THIS AMENDMENT, INCLUDING, ITS VALIDITY, INTERPRETATION, CONSTRUCTION, PERFORMANCE AND ENFORCEMENT (INCLUDING, ANY CLAIMS SOUNDING IN CONTRACT OR TORT LAW ARISING OUT OF THE SUBJECT MATTER HEREOF AND ANY DETERMINATIONS WITH RESPECT TO POST-JUDGMENT INTEREST).   
7.9    Incorporation of Credit Agreement Provisions.  The provisions contained in Sections 9.13, 9.14, 9.16, 9.18(b), 9.18(c), 9.18(d), 9.19, 9.23, and 9.24 of the Credit Agreement are incorporated herein by reference to the same extent as if reproduced herein in their entirety.
