Section 9. Reference to and Effect on the Credit Agreement.

(a) Upon the Third Amendment Effective Date and thereafter, each reference in the Credit Agreement to “this Agreement,” “hereunder,” “hereof,” “herein,” or words of like import, shall mean and be a reference to the Credit Agreement as amended hereby.

(b) Except as specifically amended by this Amendment, the Credit Agreement shall remain in full force and effect and is hereby ratified and confirmed.

Section 10. Cost and Expenses. Each of Parent and Borrower agrees to pay fees and expenses in connection with this Amendment pursuant to the terms and conditions of Section 12.04(a) of the Credit Agreement.

Nothing contained in this Amendment nor any past indulgence by Administrative Agent, the Swing Line Lender, any Issuing Lender or any

Lender, nor any other action or inaction on behalf of Administrative Agent, the Swing Line Lender, any Issuing Lender or any Lender shall constitute or be deemed to constitute an election of remedies by Administrative Agent, the Swing Line Lender, any Issuing Lender or any Lender.

Section 16. Loan Document. This Amendment is a Loan Document.

Section 17. NO ORAL AGREEMENTS. THE RIGHTS AND OBLIGATIONS OF EACH OF THE PARTIES TO THE LOAN DOCUMENTS SHALL BE DETERMINED SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND INSTRUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED BY AND MERGED INTO SUCH WRITINGS.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH PARTIES.
