A.           The Borrower, Holdings, the Guarantors, the Lenders and the Administrative Agent, have heretofore entered into that certain Credit and Guaranty Agreement dated as of May 9, 2011 (the “Credit Agreement”). Capitalized terms used herein without definition have the meanings given such terms in the Credit Agreement.

B.           The Borrower has requested that the Credit Agreement be amended as described herein.

C.           Section 10.5(a) of the Credit Agreement provides that the Credit Agreement and the other Credit Documents may be amended with the consent of the Credit Parties, the Requisite Lenders and the Administrative Agent.

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

SECTION 1   Amendment. Effective as of the Amendment No. 1 Effective Date (as defined below) the Credit Agreement is hereby amended as follows:

(a)          The definition of “Applicable Margin” in the Credit Agreement is hereby deleted in its entirety and replaced with the following:

“Applicable Margin” means for Tranche B Term Loans, Revolving Loans and Swing Line Loans a percentage per annum equal to (i) until delivery of financial statements and a related Compliance Certificate for the first fiscal quarter ending after the Amendment No. 1 Effective Date pursuant to Section 5.1(d), (A) for Eurodollar Rate Loans 4.50% and (B) for Base Rate Loans 3.50% and (ii) thereafter, the percentages per annum set forth in the table below, based upon the Total Leverage Ratio as set forth in the most recent Compliance Certificate received by the Administrative Agent pursuant to Section 5.1(c):

Amendment No. 1 to Credit Agreement

No change in the Applicable Margin shall be effective until one Business Day after the date on which Administrative Agent shall have received the applicable financial statements and a Compliance Certificate pursuant to Section 5.1(c) calculating the Total Leverage Ratio. At any time Borrower has not submitted to Administrative Agent the applicable information as and when required under Section 5.1(c), the Applicable Margin with respect to the Tranche B Term Loans and Revolving Loans shall be determined as if the Total Leverage Ratio were in excess of 4.00:1.00. Within one Business Day of receipt of the applicable information under Section 5.1(c), Administrative Agent shall give each Lender notice of the Applicable Margin in effect from such date. In the event that any financial statement or certificate delivered pursuant to Section 5.1 is shown to be inaccurate (at a time when this Agreement is in effect and unpaid Obligations under this Agreement are outstanding (other than indemnities and other contingent obligations not yet due and payable)), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin for any period (an “Applicable Period”) than the Applicable Margin applied for such Applicable Period, then (i) Borrower shall immediately deliver to Administrative Agent a correct certificate required by Section 5.1 for such Applicable Period, (ii) the Applicable Margin shall be determined using the applicable Total Leverage Ratio calculated in such correct certificate delivered pursuant to clause (i) above and (iii) Borrower shall immediately pay to Administrative Agent the accrued additional interest owing as a result of such increased Applicable Margin for such Applicable Period. Nothing in this paragraph shall limit the right of Administrative Agent or any Lender under Section 2.10 or Section 8.

(b)          The definition of “Mortgage Property” in the Credit Agreement is hereby deleted in its entirety and replaced with the following:

“Mortgaged Property” shall mean (a) each Material Real Estate Asset identified as a Mortgaged Property on Schedule 5.11 and (b) each Material Real Estate Asset, if any, which shall be subject to a Mortgage delivered after the Closing Date pursuant to Section 5.11.”

(c)          Section 2.13(c) of the Credit Agreement is hereby deleted in its entirety and replaced with the following:

Amendment No. 1 to Credit Agreement

“(c)          In the event that the Tranche B Term Loans are repaid in whole or in part pursuant to Section 2.13(a) on or after the Amendment No. 1 Effective Date but on or prior to the first anniversary of the Amendment No. 1 Effective Date with the proceeds of other loans with a Yield that is lower than the Yield of the Tranche B Term Loan, Borrower shall pay to each Tranche B Term Loan Lender a prepayment premium of 1.00% of the amount of such Lender’s Tranche B Term Loan so repaid.”

(d)          The table set forth in Section 2.14(d) of the Credit Agreement is hereby deleted in its entirety and replaced with the following:

(e)          Clause 1(D) of the first proviso in Section 2.23 of the Credit Agreement is hereby deleted in its entirety and replaced with the following:

“(D) if such removal is in connection with a reduction in the interest rates or fees payable with respect to the Tranche B Term Loans prior to the first anniversary of the Amendment No. 1 Effective Date, a fee equal to 1% of the principal amount of such Terminated Lender’s Tranche B Term Loan;”

(f)          Section 6.7 of the Credit Agreement is hereby deleted in its entirety and replaced with the following:

Section 6.7           Maximum Total Leverage Ratio.Holdings shall not permit the Total Leverage Ratio as of the last day of any Fiscal Quarter, beginning with the Fiscal Quarter ending June 30, 2012, to exceed the correlative ratio indicated:
