In furtherance of Section 1 above, the Administrative Agent, Holdings and the Company agree that concurrently with the effectiveness of the Novation, the definitions of “Borrower” and “Original Guarantors” in Section 1.1 of the Credit Agreement shall be amended in their entirety to read as follows:

“Borrower” shall mean Holdings or any Borrowing Subsidiary.

“Original Guarantors” shall mean (a) with respect to any obligations of Holdings and any Borrowing Subsidiary, the Company; and (b) with respect to the obligations of any Borrowing Subsidiary, Holdings.

Section 3 CONSENT. Notwithstanding Section 5.17 of the Credit Agreement or any other provision of any Loan Document, the Required Lenders consent to Holdings using the proceeds of Loans to make a contribution to the Company for the purpose of repaying BMS Intercompany Debt.

Section 4 REPRESENTATIONS AND WARRANTIES.

Section 5 EFFECTIVENESS.
