"(g)    Notwithstanding anything to the contrary in this Agreement, for purposes of (i) measuring the relevant financial ratios and basket availability with respect to the incurrence of any Indebtedness (including any Incremental Term Facilities or Incremental Revolving Facility) or Liens or the making of any Investments or Restricted Payments or (ii) determining compliance with the representations and warranties or the occurrence of any Default or Event of Default, in each case, in connection with a Limited Condition Acquisition, if Borrower has made an LCA Election with respect to such Limited Condition Acquisition, the date of determination of whether any such action is permitted hereunder shall be deemed to be the date on which the definitive documentation with respect to such Limited Condition Acquisition is entered into (the "LCA Test Date") and, if, after giving pro forma effect to the Limited

Condition Acquisition and the other transactions to be entered into in connection therewith as if they had occurred at the beginning of the most recent Fiscal Quarter ending prior to the LCA Test Date, a Default or Event of Default shall not then have occurred and be continuing and Borrower could have taken such action on the relevant LCA Test Date in compliance with such financial ratio, basket, representation or warranty, such financial ratio, basket, representation or warranty and such condition with respect to the lack of Default or Event of Default shall be deemed to have been complied with. For the avoidance of doubt, such ratios and other provisions shall not be tested at the time of the consummation of such Limited Condition Acquisition and, if Borrower has made an LCA Election for any Limited Condition Acquisition, then in connection with any subsequent calculation of any financial ratio or basket availability on or following the relevant LCA Test Date and prior to the earlier of (x) the date on which such Limited Condition Acquisition is consummated or (y) the date the definitive agreement for such Limited Condition Acquisition is terminated or expires without consummation of such Limited Condition Acquisition, any such financial ratio or basket availability shall be calculated (and tested) (I) on a pro forma basis assuming such Limited Condition Acquisition and other transactions in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof) have been consummated until such time as the applicable Limited Condition Acquisition has actually closed or the definitive agreement with respect thereto has been terminated and (II) with respect to the making of any Restricted Payments, on a standalone basis without giving effect to such Limited Condition Acquisition and other transactions in connection therewith."

(g)    Section 2.4(a) of the Credit Agreement is hereby amended and restated in its entirety to read as follows.

"Borrower Request. The Borrower may at any time and from time to time after the Closing Date by written notice to the Administrative Agent elect to request the establishment of one or more new term loan facilities or an increase in any existing tranche of Term Loans (each, an "Incremental Term Facility") with term loan commitments (each, an "Incremental Term Loan Commitment") in an aggregate principal amount, when combined with the aggregate amount of Incremental Revolving Commitments under Section 3.16) and all Incremental Equivalent Debt under Section 2.5, not in excess of: (i) $300,000,000 plus (ii) the aggregate amount of all voluntary prepayments of Term Loans and voluntary prepayments of Revolving Loans with a corresponding permanent reduction of the Revolving Commitments plus (iii) the maximum amount of additional Loans that could be incurred by the Borrower at such time without causing the Consolidated Secured Leverage Ratio to be greater than 4.00 to 1.0, calculated after giving pro forma effect to the incurrence of such additional amount and the use of proceeds thereof, excluding the cash proceeds of any Incremental Term Loans or Incremental Revolving Commitments and assuming the full amount of any Incremental Revolving Commitments are borrowed (whether or not funded or outstanding) (it being understood and agreed that unless notified by the Borrower, (I) the Borrower shall be deemed to have utilized, amounts of the type described in clause (iii) above prior to the utilization of amounts under clauses (i) or (ii) above and (II) Loans may be incurred in respect of any or all of clauses (i), (ii) and (iii) above, and the proceeds from any such incurrence in respect of clauses (i), (ii) and (iii) above, may be utilized in a single transaction by, first, calculating the incurrence in respect of clause (iii) above (without giving effect to any incurrence in respect of clause (i) or (ii)), second, calculating the incurrence in respect of clause (ii) above and, third, calculating the incurrence in respect of clause (i) above); provided that the Borrower may redesignate any such Indebtedness originally designated as incurred pursuant to clause (i) above if, at the time of such redesignation, the Borrower would be permitted to incur under clause (iii) the aggregate principal amount of Indebtedness being so redesignated (for purposes of clarity, with any such redesignation having the effect of increasing the Borrower’s ability to incur indebtedness under clause (i) above as of the date of such redesignation by the amount of such Indebtedness so redesignated); and in minimum

increments of $10,000,000 (or such lesser minimum increments as the Administrative Agent shall agree in its sole discretion) (the foregoing amount, the "Available Incremental Amount"). Notwithstanding anything in this Agreement to the contrary, any Incremental Term Loans the proceeds of which are used to repay or otherwise redeem, repurchase or retire Term Loans or Senior Notes shall not utilize any portion of the Available Incremental Amount and shall not reduce the Available Incremental Amount. Each such notice shall specify (i) the date (each, a "Term Loan Increase Effective Date") on which the Borrower proposes that the Incremental Term Loan Commitment shall be effective, which shall be a date not less than ten (10) Business Days after the date on which such notice is delivered to the Administrative Agent (or such earlier date as the Administrative Agent shall agree in its sole discretion) and (ii) the identity of each Person (which, if not a Lender, an Approved Fund or an Affiliate of a Lender, shall be reasonably satisfactory to the Administrative Agent) to whom the Borrower proposes any portion of such Incremental Term Loan Commitment be allocated and the amounts of such allocations."

(h)    Section 4.1(b) of the Credit Agreement is hereby amended to replace the reference to "the Amendment No. 2 Effective Date" with a reference to "the Amendment No. 4 Effective Date".

"assignments, licenses, leases or subleases granted to third parties or the Borrower or any Restricted Subsidiary in the ordinary course of business which, individually or in the aggregate, do not materially detract from the value of the Collateral taken as a whole or materially interfere with the business of the Borrower and its Restricted Subsidiaries;"

(l)    Section 8.5(g) of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

"assignments, licenses or sublicenses with respect to Intellectual Property, leases or subleases granted to third parties in the ordinary course of business which, in the aggregate, do not materially detract from the value of the Collateral taken as a whole or materially interfere with the business of the Loan Parties and their Restricted Subsidiaries;"

(m)    Section 8.5(n) of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

"the abandonment or other Disposition of Intellectual Property rights (including allowing any registrations or any applications for registration of any Intellectual Property rights to lapse or go abandoned) to the extent the Borrower determines in its reasonable business judgment that (i) such Intellectual Property rights are not commercially reasonable to maintain under the circumstances and (ii) such Disposition would not materially interfere with the business of the Borrower and its Restricted Subsidiaries;"

(n)    Section 8.5(r) of the Credit Agreement is hereby amended to replace the words "for all such Dispositions from the Closing Date" with the words "during any fiscal year".
