1. Amendment to Credit Agreement.

(a) Section 1.01 (Defined Terms) of the Credit Agreement is amended to delete the definition of “Applicable Rate” in its entirety and replace it with the following definition:

“Applicable Rate” means, for any day, the rate per annum set forth below opposite the applicable Level then in effect (based on the Consolidated Leverage Ratio):

Any increase or decrease in the Applicable Rate resulting from a change in the Consolidated Leverage Ratio shall become effective as of the first Business Day immediately following the date a Compliance Certificate is delivered pursuant to Section 6.02(a); provided that, if a Compliance Certificate is not delivered when due in accordance with such Section, then, upon the request of the Required Lenders, Pricing Level 3 shall apply, in each case as of the fifth Business Day after the date on which such Compliance Certificate was required to have been delivered and in each case shall remain in effect until the first Business Day following the date on which such Compliance Certificate is delivered. Notwithstanding anything to the contrary contained in this definition, (a) the determination of the Applicable Rate for any period shall be subject to the provisions of Section 2.l0(b) and (b) the Applicable Rate as of March 28, 2013 shall be set forth in Level 2 until the first Business Day immediately following the date a Compliance Certificate is delivered to Agent pursuant to Section 6.02(a) for the fiscal quarter ending March 31, 2013. Any adjustment in the Applicable Rate shall be applicable to all Credit Extensions then existing or subsequently made or issued.”

2. Conditions. This Amendment shall be effective as of the date first set forth above once each of the following has been delivered to Agent, each in form and substance reasonably acceptable to Agent:

(a) this Amendment executed by Borrower, the Lenders, and Agent; and

(b) the Guarantors’ Consent and Agreement attached hereto, executed by each of the Guarantors.

3. Representations and Warranties. Borrower represents and warrants to Agent and each Lender that (a) it possesses all requisite power and authority to execute, deliver and comply with the terms of this Amendment, (b) this Amendment has been duly authorized and approved by all requisite corporate action on the part of Borrower, (c) no other consent of any Person (other than Agent and the Lenders) is required for this Amendment to be effective, (d) the execution and delivery of this Amendment does not violate its organizational documents, (e) the representations and warranties in each Loan Document to which it is a party are true and correct in all material respects on and as of the date of this Amendment as though made on the date of this Amendment (except to the extent that such representations and warranties speak to a specific date), (f) it is in full compliance with all covenants and agreements contained in each Loan Document to which it is a party, and (g) no Default or Event of Default has occurred and is continuing. The representations and warranties made in this Amendment shall survive the execution and delivery of this Amendment. No investigation by Agent or any Lender is required for Agent or any Lender to rely on the representations and warranties in this Amendment.

4. Scope of Amendment; Reaffirmation; Release. All references to the Credit Agreement shall refer to the Credit Agreement as amended by this Amendment. Except as affected by this 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 Amendment) and any other Loan Document, the terms of the Credit Agreement shall control and such other document shall be deemed to be amended to conform to the terms of the Credit Agreement. Borrower hereby reaffirms its obligations under the Loan Documents to which it is a party and agrees that all Loan Documents to which it is a party remain in full force and effect and continue to be legal, valid, and binding obligations enforceable in accordance with their terms (as the same are affected by this Amendment).

5. Miscellaneous.

(a) No Waiver of Defaults. This Amendment does not constitute (i) a waiver of, or a consent to, (A) any provision of the Credit Agreement or any other Loan Document not expressly referred to in this Amendment, or (B) any present or future violation of, or default under, any provision of the Loan Documents, or (ii) a waiver of Agent’s or any Lender’s right to insist upon future compliance with each term, covenant, condition and provision of the Loan Documents.
