Nothing in this Third Amendment extinguishes, novates or releases any right, claim, Lien, security interest or entitlement of any of the Lenders, the Issuing Bank or the Administrative Agent created by or contained in any of such documents nor is Borrower released from any covenant, warranty or obligation created by or contained herein or therein.

4.Guarantors’ Ratification. Each Guarantor by its execution in the space provided below under “ACKNOWLEDGED for purposes of Section 4” 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 Third 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 any of the other Loan Documents (other than the Guaranty or any other Loan Document to which a Guarantor is a party).

5.Conditions to Effectiveness of Third Amendment. This Third 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 Third Amendment, and shall have received a duly executed acknowledgement of Section 4 of this Third 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.

6.No Implied Amendment, Waiver or Consent. This Third 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.

7.Miscellaneous. This Third Amendment is a Loan Document. Except as affected by this Third 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 Third Amendment, and any other Loan Document, the terms of the Credit Agreement will control and the other document will be deemed to be amended to conform to the terms of the Credit Agreement. All references to the Credit Agreement will refer to the Credit Agreement as amended by this Third Amendment and any other amendments properly executed among the parties. Borrower 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 Third Amendment or are amended in connection with this Third Amendment). AS A MATERIAL INDUCEMENT TO THE ADMINISTRATIVE AGENT AND LENDERS PARTY HERETO TO ENTER INTO THIS THIRD AMENDMENT, BORROWER RELEASES THE ADMINISTRATIVE AGENT, THE ISSUING BANK, 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 THIRD AMENDMENT EFFECTIVE DATE. NO COURSE OF DEALING BETWEEN BORROWER OR ANY OTHER PERSON, ON THE ONE HAND, AND THE ADMINISTRATIVE AGENT, ISSUING BANK AND THE LENDERS, ON THE OTHER, WILL BE DEEMED TO HAVE ALTERED OR AMENDED THE CREDIT AGREEMENT OR AFFECTED BORROWER’S, THE ADMINISTRATIVE AGENT’S, THE ISSUING BANK’S OR THE LENDERS’ RIGHT TO ENFORCE THE CREDIT AGREEMENT AS WRITTEN. This Third Amendment will be binding upon and inure to the benefit of each of the undersigned and their respective successors and permitted assigns.

8.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 satisfactory to the Administrative Agent and its counsel.

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

10.Interpretation.  Wherever possible each provision of this Third Amendment shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Third 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 Third Amendment.

11.Multiple Counterparts. This Third 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 Third 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 Bank. 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.

12.Governing Law.  This THIRD 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.
