As of the date hereof, Consenting Lenders holding more than fifty percent (50%) of the aggregate amount of the Aggregate Commitments have agreed to the extension and, subject to the satisfaction of the conditions in Section 2.21(c) of the Credit Agreement, the Facility Termination Date as to the Consenting Lenders shall be extended to October 26, 2018. Subject to the right of Borrower pursuant to Section 2.21(b) of the Credit Agreement to replace the Commitment of any Non-Consenting Lenders for the remaining duration of the Credit Agreement, the Facility Termination Date as to the Non-Consenting Lenders remains unchanged.

2.1    The extension of the Facility Termination Date pursuant to Article I shall become effective as of the date (the “Extension Date”) when, and only when, each of the following conditions precedent shall have been satisfied:

(b)The Borrower shall have paid:

(i)to the Administrative Agent, for the account of each Lender agreeing to the extension, an extension fee in the amount of 0.06% of such Lender’s Commitment as of the Extension Date, which extension fee once paid will be fully earned and nonrefundable; and

(ii)all other fees and reasonable expenses of the Administrative Agent and the Lenders required under the Credit Agreement and any other Loan Document to be paid on or prior to the Extension Date (including reasonable fees and expenses of counsel) in connection with this Agreement.

(c)The Administrative Agent shall have received a certificate (the statements contained in which shall be true) of a duly authorized officer of the Borrower stating that both before and after giving effect to such extension of the Facility Termination Date (i) no Default has occurred and is continuing and (ii) all representations and warranties contained in Article 5 of the Credit Agreement are true and correct in all material respects on and as of the Extension Date, except for such representations or warranties which by their terms are made as of a specified date, which shall be true and correct as of such specified date.
