“Section 2.13. Alternative Rate of Interest. (a) If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(i) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(ii) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, e-mail or facsimile as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Revolving Borrowing, such Borrowing shall be made as an ABR Borrowing; provided that if the circumstances giving rise to such notice affect only one Type of Borrowings, then the other Type of Borrowings shall be permitted.

(b) Notwithstanding anything to the contrary in Section 2.13(a) above, if the Administrative Agent has made the determination (such determination to be conclusive absent manifest error) that (i) the circumstances described in Section 2.13(a)(i) or (a)(ii) have arisen and that such circumstances are unlikely to be temporary, (ii) any applicable interest rate specified herein is no longer a widely recognized benchmark rate for newly originated loans in the U.S. syndicated loan market in the applicable currency or (iii) the applicable supervisor or administrator (if any) of any applicable interest rate specified herein or any Governmental Authority having, or purporting to have, jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which any applicable interest rate specified herein shall no longer be used for determining interest rates for loans in the U.S. syndicated loan market in the applicable currency, then the Administrative Agent may, to the extent practicable (in consultation with the Borrower and as determined by the Administrative Agent to be generally in accordance with similar situations in other transactions in which it is serving as administrative agent or otherwise consistent with market practice generally), establish a replacement interest rate (the

-3-

“Replacement Rate”), in which case, the Replacement Rate shall, subject to the next two sentences, replace such applicable interest rate for all purposes under the Loan Documents unless and until (A) an event described in Section 2.13(a)(i), (a)(ii), (b)(i), (b)(ii) or (b)(iii) occurs with respect to the Replacement Rate or (B) the Required Lenders (directly, or through the Administrative Agent) notify the Borrower that the Replacement Rate does not adequately and fairly reflect the cost to the Lenders of funding the Loans bearing interest at the Replacement Rate; provided that, if such Replacement Rate of interest as so determined would be less than zero, such rate shall be deemed to be zero for the purposes of this Agreement. In connection with the establishment and application of the Replacement Rate, this Agreement and the other Loan Documents shall be amended solely with the consent of the Administrative Agent and the Borrower, as may be necessary or appropriate, in the opinion of the Administrative Agent, to effect the provisions of this Section 2.13. Notwithstanding anything to the contrary in this Agreement or the other Loan Documents (including, without limitation, Section 9.02), such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the Administrative Agent shall not have received, within five (5) Business Days of the delivery of such amendment to the Lenders, written notices from such Lenders that in the aggregate constitute Required Lenders, with each such notice stating that such Lender objects to such amendment (which such notice shall note with specificity the particular provisions of the amendment to which such Lender objects). To the extent the Replacement Rate is approved by the Administrative Agent in connection with this clause (b), the Replacement Rate shall be applied in a manner consistent with market practice; provided that, in each case, to the extent such market practice is not administratively feasible for the Administrative Agent, such Replacement Rate shall be applied as otherwise reasonably determined by the Administrative Agent (it being understood that any such modification by the Administrative Agent shall not require the consent of, or consultation with, any of the Lenders).”

7. Amendment to Section 3.10. Section 3.10 of the Credit Agreement is hereby amended to add the following sentence immediately following the last sentence of said Section 3.10:

“As of the First Amendment Effective Date, all of the information included in the Beneficial Ownership Certification is true and correct in all material respects.”
