3.                                      Representations.  The Borrower represents and warrants that the representations and warranties contained in the Credit Agreement and the representations and warranties contained in the other Loan Documents are true and correct in all material respects on and as of the date this Eighth Amendment becomes effective pursuant to Section 6 as if made on and as of such date, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they shall be true and correct in all material respects as of such earlier date.

4.                                      Loan Parties’ Ratification. Subject to the conditions set out in Section 6, Borrower (and each Loan Party by its execution in the space provided below under “ACKNOWLEDGED for the purposes stated in Sections 4, 5 and 8”) hereby ratifies all of its Obligations under the Credit Agreement and each of the other Loan Documents to which it is a party (other than the Guaranty, which is specifically addressed in Section 5), and agrees and acknowledges that the Credit Agreement and each of the other Loan Documents to which it is a party (other than the Guaranty, which is specifically addressed in Section 5) are and shall continue to be in full force and effect. Nothing in this Eighth Amendment extinguishes, novates or releases any right, claim, Lien, security interest or entitlement of any of the Lenders, any Issuing Bank or the Administrative Agent created by or contained in any of such documents nor is any Loan Party released from any covenant, warranty or obligation created by or contained herein or therein.  Each Loan Party (other than the Borrower) agrees that its execution and delivery of this Eighth Amendment does not indicate or establish an approval or consent requirement by any such Loan Party under the Credit Agreement in connection with the execution and delivery of amendments to the Credit Agreement, the Notes or any of the other Loan Documents (other than any Loan Document to which such a Loan Party is a party).

5.                                      Guarantors’ Ratification. Each Guarantor by its execution in the space provided below under “ACKNOWLEDGED for the purposes stated in Sections 4, 5 and 8” hereby ratifies, confirms, acknowledges and agrees that its obligations under the Guaranty are in full force and effect and that such Guarantor continues to unconditionally and irrevocably guarantee the full and punctual payment, when due, whether at stated maturity or earlier by acceleration or otherwise, of the Obligations, and its execution and delivery of this Eighth Amendment does not indicate or establish an approval or consent requirement by any Guarantor under the Guaranty in connection with the execution and delivery of amendments to the Credit Agreement, the Notes or

13

any of the other Loan Documents (other than the Guaranty or any other Loan Document to which a Guarantor is a party).

6.                                      Conditions to Effectiveness of Eighth Amendment. This Eighth Amendment shall be effective upon the satisfaction, in the Administrative Agent’s sole discretion, of the following conditions precedent:

(i)                                     The Administrative Agent shall have executed, and shall have received from the Borrower and the Required Lenders duly executed signature pages to, this Eighth Amendment, and shall have received a duly executed acknowledgement of Sections 4, 5 and 8 of this Eighth Amendment from each Guarantor; and

(ii)                                  the Administrative Agent shall have received such other documents as the Administrative Agent or its counsel may reasonably request.

7.                                      No Implied Amendment, Waiver or Consent. This Eighth Amendment shall not constitute an amendment or waiver of any provision not expressly referred to herein and shall not be construed as a consent to any action on the part of the Borrower that would require a waiver or consent of the Lenders or Required Lenders, as applicable, or an amendment or modification to any term of the Loan Documents except as expressly stated herein.

8.                                      Miscellaneous. This Eighth Amendment is a Loan Document. Except as affected by this Eighth Amendment, the Loan Documents are unchanged and continue in full force and effect. However, in the event of any inconsistency between the terms of the Credit Agreement, as amended by this Eighth Amendment, and any other Loan Document, the terms of the Credit Agreement as amended by this Eighth Amendment will control and the other document will be deemed to be amended to conform to the terms of the Credit Agreement as amended by this Eighth Amendment. All references to the Credit Agreement will refer to the Credit Agreement as amended by this Eighth Amendment and any other amendments properly executed among the parties. Borrower and each Guarantor agrees that all Loan Documents to which it is a party (whether as an original signatory or by assumption of the Obligations) remain in full force and effect and continue to evidence its legal, valid and binding obligations enforceable in accordance with their terms (as the same are affected by this Eighth Amendment or are amended in connection with this Eighth Amendment). AS A MATERIAL INDUCEMENT TO THE ADMINISTRATIVE AGENT, THE ISSUING BANKS AND LENDERS PARTY HERETO TO ENTER INTO THIS EIGHTH AMENDMENT, BORROWER AND EACH GUARANTOR RELEASES THE ADMINISTRATIVE AGENT, THE ISSUING BANKS, THE LENDERS AND THEIR RESPECTIVE PREDECESSORS, SUCCESSORS, ASSIGNS, DIRECTORS, OFFICERS, EMPLOYEES, TRUSTEES, AGENTS AND ATTORNEYS FROM ANY LIABILITY FOR ACTIONS OR FAILURES TO ACT IN CONNECTION WITH THE LOAN DOCUMENTS PRIOR TO THE EIGHTH AMENDMENT EFFECTIVE DATE. NO COURSE OF DEALING BETWEEN BORROWER, ANY GUARANTOR OR ANY OTHER PERSON, ON THE ONE HAND, AND THE ADMINISTRATIVE AGENT, ISSUING BANKS AND THE LENDERS, ON THE OTHER, WILL BE DEEMED TO HAVE ALTERED OR AMENDED THE CREDIT AGREEMENT OR AFFECTED BORROWER’S, ANY GUARANTOR’S, THE ADMINISTRATIVE AGENT’S, THE ISSUING BANKS’ OR THE

14

LENDERS’ RIGHT TO ENFORCE THE CREDIT AGREEMENT AS AMENDED BY THIS EIGHTH AMENDMENT AS WRITTEN. This Eighth Amendment will be binding upon and inure to the benefit of each of the undersigned and their respective successors and permitted assigns.

9.                                      Form. Each agreement, document, instrument or other writing to be furnished to the Administrative Agent and/or the Lenders under any provision of this instrument must be in form and substance reasonably satisfactory to the Administrative Agent and its counsel.

10.                               Headings. The headings and captions used in this Eighth Amendment are for convenience only and will not be deemed to limit, amplify or modify the terms of this Eighth Amendment, the Credit Agreement, or the other Loan Documents.

11.                               Interpretation. Wherever possible each provision of this Eighth Amendment shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Eighth Amendment shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Eighth Amendment.

12.                               Multiple Counterparts. This Eighth Amendment may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same agreement. This Eighth Amendment may be transmitted and/or signed by facsimile, telecopy or electronic mail. The effectiveness of any such documents and signatures shall, subject to applicable law, have the same force and effect as manually-signed originals and shall be binding on all Loan Parties, all Lenders, the Administrative Agent and the Issuing Banks. The Administrative Agent may also require that any such documents and signatures be confirmed by a manually-signed original thereof; provided, however, that the failure to request or deliver the same shall not limit the effectiveness of any facsimile document or signature.

13.                               Governing Law. THIS EIGHTH AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO ANY CHOICE-OF-LAW PROVISIONS THAT WOULD REQUIRE THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION.
