(a)Each Lender party to this Amendment that is not a party to the Credit Agreement (each, a “New Extension Lender”) extends to the Borrowers, on the Amendment Date, such New Extension Lender’s Commitment in the amount designated for such New Extension Lender as set forth on Schedule I hereto, such Commitment being made on a several, and not joint and several, basis and subject to the terms and conditions set forth in the Amended Credit Agreement. Each New Extension Lender agrees that, upon the Amendment Date, such New Extension Lender will be a Lender for all purposes of the Amended Credit Agreement and the other Loan Documents (as defined in the Amended Credit Agreement), and such New Extension Lender will promptly perform in accordance with the terms thereof all obligations and requirements which are required to be performed by a Lender under the Amended Credit Agreement and the other Loan Documents (as defined in the Amended Credit Agreement). Each New Extension Lender represents and warrants that (i) it has full power and authority, and has taken all action necessary, to execute and deliver this Amendment and to consummate the transactions contemplated hereby and to become a Lender under the Amended Credit Agreement, (ii) it meets all the requirements to be an assignee under Section 8.08(b)(iii), (v) and (vi) of the Amended Credit Agreement (subject to such consents, if any, as may be required under Section 8.08(b)(iii) of the Amended Credit Agreement), (iii) from and after the Amendment Date, it shall be bound by the provisions of the Amended Credit Agreement as a Lender thereunder and shall have the obligations of a Lender thereunder, (iv) it is sophisticated with respect to decisions to acquire assets of the type represented by its Commitment and either it, or the Person exercising discretion in making its decision to acquire such Commitment, is experienced in acquiring assets of such type, (v) it has received a copy of the Credit Agreement and this Amendment, and has received or has been accorded the opportunity to receive copies of the financial statements referred to in Section 4.01(g) of the Amended Credit Agreement and such other documents and information as it deems appropriate to make its own credit analysis and decision to enter into this Amendment and to extend its Commitment, and (vi) it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and

information as it has deemed appropriate, made its own credit analysis and decision to enter into this Amendment and to extend its Commitment to the Borrowers pursuant to the terms of this Amendment and the Amended Credit Agreement. Each New Extension Lender agrees that it will, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents (as defined in the Amended Credit Agreement). Each New Extension Lender has submitted to the Administrative Agent an Administrative Questionnaire duly completed by such New Extension Lender to be used and relied upon by the Administrative Agent for all purposes of the Amended Credit Agreement.

(b)The Administrative Agent, each Fronting Bank and each Swing Line Lender consent to the execution and delivery by each New Extension Lender of this Amendment.

(c)Simultaneously with the effectiveness of this Amendment and notwithstanding any provisions of Section 2.06(b)(iii) of the Credit Agreement to the contrary, the Commitments of each of the Lenders, the outstanding amount of all Pro-Rata Advances and the participations of the Lenders in outstanding Letters of Credit and outstanding Swing Line Advances shall be reallocated among the Lenders in accordance with their respective Percentages (determined in accordance with the amount of each Lender’s Commitment set forth on Schedule I hereto). In order to effect such reallocations, each New Extension Lender and each other Lender whose Commitment as set forth on Schedule I hereto is in an amount that exceeds the amount of its “Commitment” under the Credit Agreement (each an “Assignee Lender”) shall be deemed to have purchased all right, title and interest in, and all obligations in respect of, the Commitments of the Lenders whose Commitments as set forth on Schedule I hereto are less than their respective “Commitments” under the Credit Agreement (each an “Assignor Lender”), so that the Commitments of each Lender will be as set forth on Schedule I hereto. Such purchases shall be deemed to have been effected by way of, and subject to the terms and conditions of, Assignment and Assumptions without the payment of any related assignment fee, and, except for any requested replacement promissory notes to be provided to the Assignor Lenders and Assignee Lenders in the principal amounts of their respective Commitments (or, if less, in the case of any such promissory note payable by a Borrower, such Assignor Lender’s or Assignee Lender’s pro rata share (based on the Commitments of all Lenders) of such Borrower’s Borrower Sublimit), no other documents or instruments shall be, or shall be required to be, executed in connection with such purchases and assignments (all of which are hereby waived). The Assignor Lenders and Assignee Lenders shall make such cash settlements among themselves, through the Administrative Agent, as the Administrative Agent may direct (after giving effect to any netting effected by the Administrative Agent) with respect to such reallocations and assignments.
