ARTICLE II

INCREMENTAL TERM LOANS

The terms of the Term B-1 Loans established pursuant to this Incremental Amendment shall be identical to the terms of the Term Loans outstanding immediately prior to the effectiveness of this Incremental Amendment (the “Existing Term Loans”), subject to the following additional or modified terms or as otherwise provided herein:

(a) Procedure for Borrowing Term B-1 Loans. Subject to the terms and conditions hereof and in the Term Loan Agreement, each Term B-1 Lender severally agrees to make a loan (a “Term B-1 Loan”) on the Incremental Amendment Effective Date in an amount equal to its Term B-1 Loan Commitment. The Term B-1 Loans shall be initially incurred pursuant to a single Eurodollar Borrowing, with such Borrowing to be subject to (x) an Interest Period which commences on the Incremental Amendment Effective Date and ends on the last day of the Interest Period applicable to the Existing Term Loans and (y) the Adjusted LIBO Rate applicable to the Term B-1 Loans for such period, it being understood that from and after the Incremental Amendment Effective Date the Existing Term Loans and the Term B-1 Loans shall be fungible and shall constitute a single class of Term Loans.

(b) Amortization of Term B-1 Loans.

(i) As set forth in Section 2.11(a) of the Term Loan Agreement, the Borrower shall pay to the Administrative Agent for the ratable account of the Lenders (which, for the avoidance of doubt, includes the Existing Term Loan Lenders and the Term B-1 Lenders), on each Principal Payment Date occurring prior to the Term Loan Maturity Date (commencing with the first Principal Payment Date following the Incremental Amendment Effective Date), a principal amount of the Term Loans (which, for the avoidance of doubt, includes the Existing Term Loans and the Term B-1 Loans) (as adjusted from time to time pursuant to Sections 2.12(b) and 2.13(e) of the Term Loan Agreement) equal to 0.25% of the original principal amount of the Term Loans.

(ii) As set forth in Section 2.11(b) of the Term Loan Agreement, to the extent not previously paid, the Borrower shall pay to the Administrative Agent for the ratable account of the Term B-1 Lenders the outstanding principal amount of the Term B-1 Loans on the Term Loan Maturity Date, together with accrued and unpaid interest on the principal amount to be paid to but excluding the date of payment.

(c) Designation. The Term B-1 Loans shall constitute Incremental Term Loans.
