NOW, THEREFORE, in consideration of the premises, the terms and conditions contained herein, and other good and valuable consideration, the receipt, adequacy and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Definitions. All capitalized terms used herein and in the above recitals and not expressly defined herein shall have the same respective meanings given to such terms in the Credit Agreement. Each reference to “hereof,” “hereunder,” “herein,” and “hereby” and each other similar reference and each reference to “this Agreement” and each other similar reference contained in the Credit Agreement shall from and after the date hereof refer to the Credit Agreement as amended hereby.

2. Amendments to Credit Agreement.

(a) The definition of “Maturity Date” in Section 1.01 of the Credit Agreement

is hereby amended and restated to read, in its entirety, as follows:

“Maturity Date” means September 16, 2013; provided, however, that if

such date is not a Business Day, the Maturity Date shall be the next preceding

Business Day.

3. Representations and Warranties. The Borrower hereby represents and warrants to and in favor of the Administrative Agent and the Lenders as follows:

(a) each representation and warranty set forth in Article V of the Credit Agreement is true and correct in all material respects as of the date hereof (except with respect to representations and warranties made as of an expressed date, in which case such representations and warranties shall have been true and correct in all material respects as of such date);

(b) the Borrower has the corporate power and authority to enter into this Amendment and to do all acts and things as are required or contemplated hereunder to be done, observed and performed by it;

(c) this Amendment has been duly authorized, validly executed and delivered by one or more Responsible Officers of the Borrower, and constitutes the legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with its terms; and

(d) the execution and delivery of this Amendment and performance by the Borrower under the Credit Agreement, as amended hereby, does not and will not require the consent or approval of any regulatory authority or governmental authority or agency having jurisdiction over the Borrower which has not already been obtained, nor be in contravention of or in conflict with any Organization Documents of the Borrower, or any provision of any statute, judgment, order, indenture, instrument, agreement, or undertaking, to which the Borrower is party or by which the Borrower’s assets or properties are bound.

4. Conditions Precedent to Effectiveness of Amendment. This amendment shall be effective upon satisfaction of the following conditions precedent, each in form and substance satisfactory to the Administrative Agent, as applicable:

(a) all of the representations and warranties of the Borrower under Section 3 hereof which are made as of the date hereof, shall be true and correct in all material respects; and

(b) execution and delivery of this Amendment by each of the Borrower, the Administrative Agent, and the Lenders.

5. Effect of Amendment; No Novation. Except as expressly set forth herein, the Credit Agreement shall remain in full force and effect and shall constitute the legal, valid, binding and enforceable obligation of the Borrower to the Administrative Agent and the Lenders, and Borrower hereby restates, ratifies and reaffirms each and every term and condition set forth in the Credit Agreement. The terms of this Amendment are not intended to and do not serve as a novation as to the Credit Agreement, any Note or the indebtedness evidenced thereby. The parties hereto expressly do not intend to extinguish any debt or security interest created pursuant to the Credit Agreement or any document executed in connection therewith. Instead it is the express intention to affirm the Credit Agreement and the security created thereby. The amendments agreed to herein shall not constitute a modification of the Credit Agreement or a course of dealing with the Administrative Agent or the Lenders at variance with the Credit Agreement such as to require further notice by the Administrative Agent or any Lender to require strict compliance with the terms of the Credit Agreement in the future.

6. 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 counterparts, taken together, shall constitute but one and the same instrument. Delivery of an executed counterpart of this Amendment by facsimile transmission, Adobe Corporation’s Portable Document Format, or other electronic transmission shall be effective as delivery of a manually executed counterpart hereof.

7. Successors and Assigns. This Amendment shall be binding upon and inure to the benefit of the successors and permitted assigns of the parties hereto.

8. Loan Document. For avoidance of doubt, the Borrower, the Administrative Agent, and the Lenders hereby acknowledge and agree that this Amendment is a Loan Document.

9. No Default. To induce the Administrative Agent and the Lenders to enter into this Amendment and to continue to make advances pursuant to the Credit Agreement (subject to the terms and conditions thereof), the Borrower hereby acknowledges and agrees that, as of the date hereof, and after giving effect to the terms hereof, there exists (a) no Default or Event of Default and (b) no right of offset, defense, counterclaim, claim, or objection in favor of the Borrower or arising out of or with respect to any of the Loans or other obligations of the Borrower owed to the Administrative Agent or any Lenders under the Credit Agreement or any other Loan Document.

10. Further Assurances. The Borrower agrees to take, at Borrower’s expense, such further actions as the Administrative Agent shall reasonably request from time to time to evidence the amendments set forth herein and the transactions contemplated hereby.

11. Severability. Any provision of this Amendment which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction.

12. Recitals Incorporated Herein. The preamble and the recitals to this Amendment are hereby incorporated herein by this reference.

13. Section References. Section titles and references used in this Amendment shall be without substantive meaning or content of any kind whatsoever and are not a part of the agreements among the parties hereto evidenced hereby.
