			“Net Senior Debt Ratio” — as of any date of determination, the ratio of (i) Consolidated Net Senior Debt as of the last day of the fiscal quarter of Borrower ending on the date of determination, to (ii) Consolidated EBITDA for the four consecutive fiscal quarters then ended.
			“Subordinated Indebtedness” — at a particular date, without duplication, any Indebtedness for which the Borrower or any

Subsidiary is directly and primarily liable that is expressly subordinated in right of payment to the payment of all Indebtedness of the Borrower incurred under and in compliance with the terms of the Credit Agreement and the Loan Documents on a basis substantially equivalent to the subordination under the Current Indentures (as defined in section 7.1(f) hereof).
