(e)    If (and only if) the total of the Commitments of the Lenders that have agreed to extend their Revolving Credit Maturity Date is more than 50% of the aggregate amount of the Commitments in effect immediately prior to the applicable Extension Date, then, effective as of the applicable Extension Date, the Revolving Credit Maturity Date of each Extending Lender and of each Additional Commitment Lender shall be extended to the date that is one year after the Existing Revolving Credit Maturity Date (except that, if such date is not a Business Day, such Revolving Credit Maturity Date as so extended shall be the next preceding Business Day) and each Additional Commitment Lender shall thereupon become a “Lender” for all purposes of this Agreement and shall be bound by the provisions of this Agreement as a Lender hereunder and shall have the obligations of a Lender hereunder.

(f)    Notwithstanding the foregoing, (x) no more than two (2) extensions of the Revolving Credit Maturity Date shall be permitted hereunder (and not more than one such extension may be requested during any nine-month period) and (y) any extension of any Revolving Credit Maturity Date pursuant to this Section 2.24 shall not be effective with respect to any Extending Lender unless:

(i)    there shall exist no Default or Event of Default on the applicable Extension Date and immediately after giving effect thereto;

(ii)    the representations and warranties made by the Borrower contained herein shall be true and correct in all material respects (other than to the extent qualified by materiality or “Material Adverse Effect”, in which case, such representations and warranties shall be true and correct) with the same effect as though such representations and warranties had been made on and as of the date of such extension (or to the extent that such representations and warranties specifically refer to an earlier date, as of such earlier date); and

(iii)    the Administrative Agent shall have received a certificate from the Borrower signed by an Authorized Officer of the Borrower (A) certifying the accuracy of the foregoing clauses (i) and (ii) and (B) certifying and attaching the resolutions adopted by the Borrower approving or consenting to such extension.

(g)    On the Revolving Credit Maturity Date of each Non-Extending Lender, (i) the Revolving Credit Commitment of each Non-Extending Lender shall automatically terminate and (ii) the Borrower shall repay such Non-Extending Lender in accordance with Section 2.11 (and shall pay to such Non-Extending Lender all of the other obligations owing to it under this Agreement) and after giving effect thereto shall prepay any Loans outstanding on such date (and pay any additional amounts required pursuant to Section 2.17) to the extent necessary to keep outstanding Loans ratable with any revised Applicable Percentage of the respective Lenders effective as of such date, and the Administrative Agent shall administer any necessary reallocation of the Revolving Credit Exposures (without regard to any minimum borrowing, pro rata borrowing and/or pro rata payment requirements contained elsewhere in this Agreement).

(h)    This Section shall supersede any provisions in Section 9.02 to the contrary.

Anti-Corruption Laws and Sanctions. The Borrower has implemented and maintains in effect policies and procedures designed to ensure compliance by the Borrower, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions, and the Borrower, its Subsidiaries and their respective officers and employees and to the knowledge of the Borrower its directors and agents, are in compliance with Anti-Corruption Laws and applicable Sanctions in all material respects. None of (a) the Borrower, any Subsidiary or to the knowledge of the Borrower or such Subsidiary any of their respective directors, officers or employees, or (b) to the knowledge of the Borrower, any agent of the Borrower or any Subsidiary that will act in any capacity in connection with or benefit from the credit facility established hereby, is a Sanctioned Person.
