““Applicable Margin” means, (1) with respect to any B Term Loan (x) in the case of Eurocurrency Rate Loans, (i) 2.75% per annum (for any day prior to the First Amendment Effective Date), (ii) 2.25% per annum (for any day on or after the First Amendment Effective Date but prior to the Second Amendment Restatement Date), (iii) 2.00% per annum (for any day on or after the Second Amendment Restatement Date but prior to the Third Amendment Effective Date) and (iv) 1.75% per annum (for any day on or after the Third Amendment Effective Date) and (y) in the case of Base Rate Loans, (i) 1.75% per annum (for any day prior to the First Amendment Effective Date), (ii) 1.25% per annum (for any day on or after the First Amendment Effective Date but prior to the Second Amendment Restatement Date), (iii) 1.00% per annum (for any day on or after the Second Amendment Restatement Date but prior to the Third Amendment Effective Date) and (iv) 0.75% per annum (for any day on or after the Third Amendment Effective Date) and (2) with respect to any A3 Term Loan or any A5 Term Loan (a) at any time prior to the date on which the financial statements and accompanying Compliance Certificate for the first full fiscal quarter of Holdings ending after the Closing Date are delivered pursuant to Section 5.08(a) or (b), as applicable, (x) in the case of Eurocurrency Rate Loans, 2.25% per annum and (y) in the case of Base Rate Loans, 1.25% per annum, (b) for any day thereafter but prior to the Second Amendment Restatement Date, the percentage per annum set forth in the table below titled “Pre-Second Amendment A3 Term Loan or A5 Term Loan”, in each case, under the appropriate caption determined by reference to the Senior Secured Leverage Ratio at the end of the most recent fiscal quarter of Holdings (subject to the penultimate paragraph of this definition), (c) for any day on or following the Second Amendment Restatement Date but prior to the Fourth Amendment Effective Date, the percentage per annum set forth in the table below titled “Pre-Fourth Amendment A3 Term Loan or A5 Term Loan, No Lien Suspension Period”, in each case, under the appropriate caption determined by reference to the Senior Secured Leverage Ratio at the end of the most recent fiscal quarter of Holdings (subject to the penultimate paragraph of this definition), (d) for any day on or following the Fourth Amendment Effective Date, other than during a Lien Suspension Period, the percentage per annum set forth in the table below titled “Post-Fourth Amendment A5 Term Loan, No Lien Suspension Period”, in each case, under the appropriate caption determined by reference to the Senior Secured Leverage Ratio at the end of the most recent fiscal quarter of Holdings (subject to the penultimate paragraph of this definition), or (e) for any day on or following the Fourth Amendment Effective Date during a Lien Suspension Period, the percentage per annum set forth in the table below titled “Post-Fourth Amendment A5 Term Loan, Lien Suspension Period”, in each case, under the appropriate caption determined by reference to the corporate credit rating or corporate family rating, as applicable (each, a “Corporate Rating”), with respect to Holdings and the Subsidiaries on a consolidated basis by S&P or Moody’s, respectively on such date (subject to the last paragraph of this definition):

The Applicable Margin with respect to any A3 Term Loan and any A5 Term Loan, other than for any day during a Lien Suspension Period, shall be re-determined quarterly on the first Business Day following the date of delivery to the Agent of the calculation of the Senior Secured Leverage Ratio based on the financial statements and the accompanying Compliance Certificate required to be delivered pursuant to Section 5.08(a) or (b), as applicable. If the Agent has not received such financial statements and the accompanying Compliance Certificate setting forth such calculation when due pursuant to Section 5.08(a) or (b), as applicable, the Applicable Margin (in the case of any A3 Term Loan or any A5 Term Loan) shall be determined as if the highest Pricing Level of the applicable table above shall have applied until the first Business Day after the date of delivery of such financial statements and the accompanying Compliance Certificate setting forth such calculation to Agent. At any time upon the occurrence and during the continuance of any Event of Default, the Applicable Margin (in the case of any A3 Term Loan or any A5 Term Loan) shall be set at the highest Pricing Level of the applicable table above. In the event that any financial statement or Compliance Certificate delivered pursuant to Section 5.08(a) or (b), as applicable, is shown to be inaccurate, and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin (in the case of any A3 Term Loan or any A5 Term Loan) for any period (a “Margin Applicable Period”) than the Applicable Margin actually applied for such Margin Applicable Period, then (i) the Borrower shall promptly upon becoming aware of any such inaccuracy deliver to the Agent a corrected Compliance Certificate for such Margin Applicable Period and (ii) the Borrower shall promptly pay to the Agent the accrued additional amounts owing as a result of such increased Applicable Margin for such Margin Applicable Period.

For purposes of determining the Applicable Margin during a Lien Suspension Period, if either Moody’s or S&P shall not have in effect a Corporate Rating of Holdings and the Subsidiaries on a consolidated basis (other than by reason of the circumstances referred to in the last sentence of this definition), then the Borrower and the Lenders shall negotiate in good faith to agree upon another rating agency to be substituted by an amendment to this Agreement for the rating agency which shall not have a Corporate Rating in effect, and pending the effectiveness of such amendment, the Applicable Margin shall be determined by reference to the available Corporate Rating; (b) if the Corporate Ratings established or deemed to have been established by Moody’s and S&P shall fall within different Pricing Levels, the Applicable Margin shall be based on the higher of the two Corporate Ratings, unless one of the two ratings is two Pricing Levels lower than the other, in which case the Applicable Margin shall be determined by reference to the Pricing Level next below that of the higher of the two Corporate Ratings; and (c) if the Corporate Rating established or deemed to have been established by Moody’s or S&P shall be changed (other than as a result of a change in the rating system of Moody’s or S&P), such change shall be effective as of the date on which it is first announced by the applicable rating agency. Each change in the Applicable Margin based on the Corporate Ratings shall apply during the period commencing on the effective date of such change and ending on the date immediately preceding the effective date of the next such change. If the rating system of Moody’s or S&P shall change, or if either such rating agency shall cease to be in the business of rating corporate debt obligations, the Borrower and the Lenders shall negotiate in good faith to amend the definition of “Applicable Margin” to reflect such changed rating system or the unavailability of ratings from such rating agency and, pending the effectiveness of any such amendment, the Applicable Margin shall be determined by reference to the Corporate Rating most recently in effect prior to such change or cessation.”

(g)    The definition of “Incremental Facility Amount” in the Existing Credit Agreement is hereby amended and restated in its entirety to read as follows:

When calculating the Incremental Facility Amount, the Borrower may utilize capacity available under both the Incremental Fixed Amount and the Incremental Ratio Amount in the same transaction and, absent direction from the Borrower, if amounts are available under both the Incremental Fixed Amount and the Incremental Ratio Amount, the Borrower will be deemed to have first utilized amounts permitted under the Incremental Ratio Amount to the extent compliant therewith before any utilization of amounts permitted under the Incremental Fixed Amount.”
