WHEREAS, each Extending Lender that is also already a Revolving Credit Lender under the Credit Agreement immediately prior to giving effect to this Amendment (each, an “Existing Lender”), that executes and delivers a counterpart signature page to this Amendment, shall be deemed, upon the effectiveness of this Amendment, to have agreed to extend the Maturity Date in respect of its Revolving Credit Commitments on the terms set forth herein; and

3

Section 4, the representations and warranties contained in Section 5.05(a) of the Credit Agreement shall be deemed to refer to the most recent financial statements furnished  pursuant to Section 6.01(a) and Section 6.01(b) of the Credit Agreement.

(d)           The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of any Lender or any Agent under any of the Loan Documents, or constitute a waiver of any provision of any of the Loan Documents.

Section 7.  Costs, Expenses.  The Borrower hereby agrees to pay on demand all reasonable out of pocket costs and expenses of the Administrative Agent and the Arrangers in connection with the preparation, execution and delivery of this Amendment and the other instruments and documents to be delivered hereunder, in accordance with the terms of Section 10.04 of the Credit Agreement.

Section 8.  Counterparts.  This Amendment may be executed in one or more counterparts (and by different parties hereto in different counterparts), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  Delivery by telecopier or other electronic transmission of a scanned image of an executed counterpart of a signature page to this Amendment shall be effective as delivery of an original executed counterpart of this Amendment.  The Administrative Agent may also require that any such documents and signatures delivered by telecopier or other electronic transmission be confirmed by a manually-signed original thereof; provided, that the failure to request or deliver

6

the same shall not limit the effectiveness of any document or signature delivered by telecopier or other electronic transmission.

Section 12.  Severability.  If any provision of this Amendment or any other Loan Document is held to be illegal, invalid or unenforceable, the legality, validity and enforceability of the remaining provisions of this Amendment and the other Loan Documents shall not be affected or impaired thereby.  The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 13.  Headings.  The headings of this Amendment are for purposes of reference only and shall not limit or otherwise affect the meaning hereof.

Section 14.  WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AMENDMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).  EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AMENDMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 14.
