B. The Borrower has requested that, pursuant to Section 10.01 of the Existing Credit Agreement, the Required Lenders consent to the amendments described herein, and the Required Lenders are willing to agree to such amendments on the terms and subject to the conditions described herein.

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the sufficiency and receipt of all of which is hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. Definitions. Capitalized terms used herein and not otherwise defined in this Amendment have the same meanings as specified in the Existing Credit Agreement, as amended by this Amendment (as so amended, the “Credit Agreement”).

SECTION 2. Amendments to Existing Credit Agreement. Effective as of the Amendment Effective Date, the Existing Credit Agreement is hereby amended as follows:

(a) Section 1.1 of the Existing Credit Agreement is amended by amending or amending and restating, as applicable, the following definitions:

“(b) setting forth reasonably detailed calculations, in the case of financial statements delivered under Section 6.01(a), beginning with the financial statements for the fiscal year of the Borrower ending September 30, 2013, of Excess Cash Flow for such fiscal year (or, solely in the case of the certificate delivered with the financial statements for the fiscal year of the Borrower ending September 30, 2013, for the 2013 ECF Period)”

(b) Section 2.03 of the Existing Credit Agreement is amended by amending and restating Section 2.03(b)(i) in its entirety as follows:

“(i) Within five (5) Business Days after financial statements have been delivered pursuant to Section 6.01(a) and the related Compliance Certificate has been delivered pursuant to Section 6.02(a), the Borrower shall, subject to clause (b)(v) of this Section 2.03, prepay an aggregate principal amount of Loans equal to (A) 50% (such percentage as it may be reduced as described below, the “ECF Percentage”) of Excess Cash Flow, if any, for the fiscal year covered by such financial statements (commencing with the fiscal year ended September 30, 2013; provided, that such prepayment for the fiscal year ending September 30, 2013 shall be calculated for the period commencing October 1, 2011 and ending September 30, 2013 (taken as one accounting period (the “2013 ECF Period”)) (each such fiscal year period and the 2013 ECF Period, an “ECF Period”) minus (B) the sum of (i) all voluntary prepayments of Loans during such ECF Period pursuant to Section 2.03(a)(i) and (ii) all voluntary prepayments of loans under the ABL Facility during such ECF Period to the extent accompanied by a corresponding permanent reduction in the commitments under the ABL Facility, in the case of each of the immediately preceding clauses (i) and (ii), to the extent such prepayments are not funded with the proceeds of Indebtedness; provided that (x) the ECF Percentage shall be 25% if the Secured Net Leverage Ratio as of the end of the ECF Period covered by such financial statements was less than or equal to 2.50 to 1.0 and greater than 1.75 to 1.0 and (y) the ECF Percentage shall be 0% if the Secured Net Leverage Ratio as of the end of the ECF Period covered by such financial statements was less than or equal to 1.75 to 1.0.”

SECTION 3. Waiver of Excess Cash Flow Prepayment. For the avoidance of doubt, except as provided in Section 2(b) above with respect to the 2013 ECF Period, the Required Lenders hereby waive any obligation of the Borrower to make a mandatory prepayment of Loans out of Excess Cash Flow pursuant to Section 2.03(b)(i) of the Existing Credit Agreement in respect of the fiscal year ended September 30, 2012.

Each of this Amendment and each other Loan Document to which any Credit Agreement Party is a party, after giving effect to the amendments pursuant to this Amendment, constitutes a legal, valid and binding obligation of such Credit Agreement Party, enforceable against such Credit Agreement Party in accordance with its terms, except as such enforceability may be limited by Debtor Relief Laws and by general principles of equity and principles of good faith and fair dealing.
