(a)Except as expressly amended or waived hereby, all of the representations, warranties, terms, covenants and conditions of the Credit Agreement and the other Loan Documents shall remain in full force and effect in accordance with their respective terms and are hereby in all respects ratified and confirmed. The waiver and amendments set forth herein shall be limited precisely as provided for herein and shall not be deemed to be a waiver of, amendment of, consent to departure from or modification of any term or provision of the Loan Documents or any other document or instrument referred to therein or of any transaction or further or future action on the part of any Borrower requiring the consent of the Administrative Agent, the Fronting Banks or the Lenders except to the extent specifically provided for herein. Except as expressly set forth herein, the Administrative Agent and the Lenders have not and shall not be deemed to have waived any of their respective rights and remedies against the Borrowers for any existing or future Unmatured Default or Event of Default. The Administrative Agent, the Fronting Banks and the Lenders reserve the right to insist on strict compliance with the terms of the Credit Agreement and the other Loan Documents, and the Borrowers expressly acknowledge such reservation of rights. Any future or additional waiver or amendment of any provision of the Credit Agreement or any other Loan Document shall be effective only if set forth in a writing separate and distinct from this Amendment and executed by the appropriate parties in accordance with the terms thereof.

(b)Upon the effectiveness of this Amendment: (i) each reference in the Existing Credit Agreement to “this Agreement”, “hereunder”, “hereof” or words of like import referring to the Existing Credit Agreement shall mean and be a reference to the Amended Agreement; and (ii) each reference in any other Loan Document to “the Credit Agreement”, “thereunder”, “thereof” or words of like import referring to the Existing Credit Agreement shall mean and be a reference to the Amended Agreement. This Amendment shall constitute a “Loan Document” for all purposes under the Credit Agreement and the other Loan Documents.

(c)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 the Lenders, the Administrative Agent or the Fronting Banks under the Existing Credit Agreement or any other Loan Document, nor constitute a waiver of any provision of the Existing Credit Agreement or any other Loan Document.

Section 7. Costs and Expenses. Each Borrower agrees to pay on demand all reasonable out-of-pocket costs and expenses incurred by the Administrative Agent and each Fronting Bank in connection with the preparation, execution, delivery, syndication and administration of this Amendment and the other documents to be delivered hereunder, including, without limitation, the reasonable fees and out-of-pocket expenses of counsel (including, but not limited to, one local counsel and any specialist counsel in each relevant jurisdiction) for the Administrative Agent and the Fronting Banks with respect thereto and with respect to advising the Administrative Agent and the Fronting Banks as to their rights and responsibilities under this Amendment. Each Borrower further agrees to pay on demand all reasonable out-of-pocket costs

-8-

and expenses, if any (including, without limitation, reasonable fees and expenses of counsel), incurred by the Administrative Agent, the Fronting Banks and the Lenders in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Amendment, the Amended 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. The Borrowers acknowledge and agree that, pursuant to Section 8.05(a) of the Credit Agreement, they are required to pay, among other costs and expenses set forth therein, the reasonable fees and expenses of counsel for the Administrative Agent (including, but not limited to, any local counsel and any specialist counsel for the Administrative Agent), in accordance with the terms thereof.

Section 8. 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 and delivered shall be deemed to be an original and all of which taken together shall constitute but one and the same instrument. Delivery of an executed signature page to this Amendment by facsimile or other electronic transmission (including, without limitation, by Adobe portable document format file (also known as a “PDF” file)) shall be as effective as delivery of a manually signed counterpart of this Amendment. The words “execution,” “executed,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Amendment or any document to be signed in connection with this Amendment and the transactions contemplated hereby shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act; provided, that nothing herein shall require the Administrative Agent to accept electronic signatures in any form or format without its prior written consent; provided, further, that, without limiting the foregoing, upon the request of the Administrative Agent, any electronic signature shall be promptly followed by such manually executed counterpart.

Section 9. Governing Law. This Amendment shall be governed by, and construed in accordance with, the laws of the State of New York.

Section 10. Miscellaneous. This Amendment shall be subject to the provisions of Sections 8.05, 8.10, 8.11 and 8.12 of the Credit Agreement, each of which is incorporated by reference herein, mutatis mutandis.

Section 11. Release. In consideration of, among other things, the Administrative Agent’s, the Fronting Banks’ and the Lenders’ execution and delivery of this Amendment, each Borrower, on behalf of itself and its agents, representatives, officers, directors, advisors, employees, subsidiaries, affiliates, successors and assigns (collectively, “Releasors”), hereby forever agrees and covenants not to xxx or prosecute against any Releasee (as hereinafter defined) and hereby forever waives, releases and discharges, to the fullest extent permitted by

-9-

law, each Releasee from any and all claims (including, without limitation, crossclaims, counterclaims, rights of set-off and recoupment), actions, causes of action, suits, debts, liens, warranties, damages and consequential damages, judgments, costs or expenses whatsoever, that such Releasor now has or hereafter may have, of whatsoever nature and kind, whether now existing or hereafter arising, whether arising at law or in equity (collectively, the “Claims”), against any or all of the Credit Parties in any capacity and their respective affiliates, subsidiaries, shareholders and “controlling persons” (within the meaning of the federal securities laws), and their respective successors and assigns and each and all of the officers, directors, employees, agents, attorneys, advisors and other representatives of each of the foregoing (collectively, the “Releasees”), based in whole or in part on facts existing on or before the Amendment Effective Date, that relate to, arise out of or otherwise are in connection with: (i) any or all of the Loan Documents or transactions contemplated thereby or any actions or omissions in connection therewith; or (ii) any aspect of the dealings or relationships between or among the Borrowers, on the one hand, and any or all of the Credit Parties, on the other hand, relating to any or all of the documents, transactions, actions or omissions referenced in clause (i) hereof. The receipt by any Borrower of any Advances or other financial accommodations made by any Credit Party after the date hereof shall constitute a ratification, adoption, and confirmation by such party of the foregoing general release of all Claims against the Releasees that are based in whole or in part on facts existing on or prior to the date of receipt of any such Advances or other financial accommodations. In entering into this Amendment, each Borrower consulted with, and has been represented by, legal counsel and expressly disclaims any reliance on any representations, acts or omissions by any of the Releasees and hereby agrees and acknowledges that the validity and effectiveness of the releases set forth above do not depend in any way on any such representations, acts and/or omissions or the accuracy, completeness or validity thereof. The provisions of this Section 11 shall survive the termination of this Amendment, the Credit Agreement, the other Loan Documents and payment in full of the Advances.
