(a) On the terms and subject to the conditions set forth herein, effective as of the Amendment Effective Date and immediately after giving effect to Section 2 hereof, each Lender (including each of the existing Lenders and each Additional Credit Lender that becomes a Lender pursuant to Section 2 hereto) reflected as having a Commitment on Schedule B hereto (an “Extending Lender”) agrees that the Maturity Date with respect to all of its Commitments reflected on such Schedule (including all the Additional Credit Commitments of each Additional Credit Lender) shall be extended to the Extended Maturity Date (the “Extended Commitments”) and that the maturity date of all the Existing Revolving Loans of each Extending Lender shall (to the extent not prepaid in accordance with Section 2(b) hereof) be extended to the Extended Maturity Date (such Revolving Loans, the “Extended Revolving Loans”).

(b) The initial Interest Period applicable to each Extended Revolving Loan that is a Eurodollar Loan shall be the then-current Interest Period applicable to the Existing Revolving Loan that has been extended, and the Applicable Rate for such Loan shall be as set forth in Section 4 for periods on and after the Amendment Effective Date.
