SECTION 2. Revolving Commitment Increase.

(a)    The Revolving Commitments of each Increased Commitment Lender shall, as of the Amendment Effective Date (as defined below), be increased in the amount set forth opposite such Increase Commitment Lenders name on Schedule 1 hereto.

(b)    As of the Amendment Effective Date, each existing Revolving Lender that is not an Increased Commitment Lender (a “Non-Increased Lender”) (without the need for execution of any document) shall be deemed to have irrevocably sold and assigned to each Increased Commitment Lender, and each Increased Commitment Lender shall be deemed to have irrevocably purchased and assumed from each Non-Increased Lender, (i) in the respective principal amounts (together with accrued interests) such interests in the Revolving Loans outstanding on the Amendment Effective Date as necessary so that, after giving effect to all such assignments and purchases, the Revolving Loans and any unused Revolving Commitments are held by the Non-Increased Lenders and the Increased Commitment Lenders ratably based on the allocation of Revolving Commitments set forth for the Lenders on Appendix A hereto and (ii) all of such Non-Increased Lenders’ rights and obligations in their respective capacities as Revolving Lenders under the Credit Agreement and the other Credit Documents in respect of such purchased and assumed Revolving Loans. Such sales, assignments, purchases and assumptions shall be deemed to have been effected pursuant to the same terms and conditions as set forth in the form of Assignment and Assumption Agreement attached as Exhibit E to the Credit Agreement. Other than this Amendment and any replacement Revolving Loan Note to be provided to any Lender that requests such replacement Note in the applicable principal amount (not to exceed such Lender’s Revolving Commitment upon giving effect to the November 2015 Increased Commitments), no document or instrument (including any Assignment and Assumption) shall be required to be executed in connection with any such sale, assignment, purchase and assumption. Each Increased Commitment Lender and Non-Increased Lender shall make such cash settlements between themselves, in a manner acceptable to and approved by the Administrative Agent, as they deem necessary and desirable with respect to such sales, assignments, purchases and assumptions. The Administrative Agent and each Borrower hereby consent to the assignments provided for in this Section 2(b). The consent of no other Person to such assignments shall be required to give effect to the November 2015 Increased Commitments.
