Finally, the Borrower hereby represents and warrants, on behalf of itself and each other Loan Party, that the execution and delivery of this Amendment and the other documents executed in connection herewith shall in no way change or modify its or any other Loan Party’s obligations as a debtor, pledgor, assignor, obligor, grantor, mortgagor and/or chargor under any Collateral Document and the other Loan Documents and shall not constitute a waiver by the Administrative Agent or the Lenders of any of their rights against any Loan Party.

Section 7. Effect of Amendment. From and after the Amendment No. 4 Effective Date, each reference in the Credit Agreement to “this Agreement”, “hereof”, or “hereunder” or words of like import, and all references to the Credit Agreement in the Loan Documents and any and all other agreements, instruments, documents, notes, certificates, guaranties and other writings of every kind and nature shall be deemed to mean the Credit Agreement as modified by this Amendment. This Amendment shall constitute a Loan Document for all purposes of the Credit Agreement and the other Loan Documents.

Section 8. Costs and Expenses. Pursuant to the terms of Section 9.03 of the Credit Agreement, the Borrower agrees to pay all reasonable and documented out-of-pocket expenses incurred by the Administrative Agent and its Affiliates in connection with the preparation, execution and enforcement of this Amendment.

Section 10. Counterparts; Integration; Effectiveness. This Amendment may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Amendment, the Credit Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the

parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. This Amendment shall become effective on the Amendment No. 4 Effective Date, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page to this Amendment by facsimile, e-mailed .pdf or any other electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Amendment.
