Subject to the terms and conditions set forth in this Section 2.03A, upon delivery of a Notice of Borrowing requesting a Borrowing in a Committed Foreign Currency pursuant to Section 2.02(a) (a “Fronting Event”), the Fronting Bank agrees, subject to the limitations set forth below, to fund the applicable amount then required to be funded in such Committed Foreign Currency by each applicable Non-Qualified Lender (a “Fronting Advance”), notwithstanding the fact that such Fronting Advance, when aggregated with the Pro Rata Share of the Facility Exposure of the Fronting Bank (in its capacity as a Lender), may exceed the amount of the Fronting Bank’s Revolving Credit Commitment; provided that after giving effect to each Fronting Advance the aggregate Equivalent in Dollars of all Fronting Advances funded by the Fronting Bank shall not exceed the respective Fronting Commitment allocated to such Non-Qualified Lender as specified on Schedule I attached hereto (such Fronting Commitments, collectively, the “Fronting Facility”). Immediately upon the making of a Fronting Advance on behalf of a Non-Qualified Lender, such Non-Qualified Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Fronting Bank a risk participation in one hundred percent (100%) of such Fronting Advance. The purchase of such risk participation in each Fronting Advance by such Non-Qualified Lender shall satisfy such Non-Qualified Lender’s funding requirements under Section 2.02(a).

(b) Fronting Commitment. If following delivery of a Notice Borrowing requesting a Borrowing in a Committed Foreign Currency pursuant to Section 2.02(a) (a “Requested Borrowing”), the Fronting Bank, based on the limitations set forth in the proviso to the first sentence of Section 2.03A, is unable to fund the entire corresponding Fronting Advance in such Committed Foreign Currency, then the Fronting Bank will give the Borrower and the Administrative Agent notice of such limitation on the day it obtains knowledge thereof (which notice may be telephonic) and the Borrower may decrease the amount of the Requested Borrowing within one (1) Business Day after receipt of such notice. If the Borrower does not reduce its Requested Borrowing to an amount that will result in the corresponding Fronting Advance being less than or equal to the available

6

Fronting Commitment subject to the limitation set forth in the proviso to the first sentence in Section 2.03A, then (1) the Requested Borrowing shall be deemed to be reduced in an amount sufficient to result in the corresponding Fronting Advances being equal to the available Fronting Commitments (a “Reduced Borrowing”) and (2) the Borrower shall be deemed to have requested an additional Borrowing in an amount equal to the Equivalent in Dollars of the excess of the Requested Borrowing over the Reduced Borrowing, which shall be made by the Lenders without the utilization of any Fronting Advances.

(c) Allocation of Payments. Following the making of any Fronting Advance by the Fronting Bank hereunder, prior to the date the applicable Non-Qualified Lender that holds the 100% risk participation in such Fronting Advance funds such risk participation pursuant to this Section 2.03A to refinance such Fronting Advance, (1) all payments of principal made in respect of any Advances funded by the Fronting Bank on behalf of such Non-Qualified Lender shall be solely for the account of the Fronting Bank, and (2) all payments of interest made in respect of any Advances funded by the Fronting Bank on behalf of such Non-Qualified Lender shall be solely for the account of such Non-Qualified Lender, provided that the interest paid to such Non-Qualified Lender shall be reduced by the Fronting Fee payable pursuant to Section 2.08(e).

(d) Sharing Events. Upon the occurrence of an Event of Default and the conversion of all Advances denominated in any Committed Foreign Currency into Dollars pursuant to Section 2.09(b)(iii) (a “Sharing Event”), the Administrative Agent shall notify each Non-Qualified Lender of its obligation to fund its participation in each Fronting Advance. Each Non-Qualified Lender shall make the amount of its participation in each such Fronting Advance available to the Administrative Agent for the account of the Fronting Bank, by deposit of such amount (in Dollars) to the Administrative Agent’s Account, in same day funds, not later than 1:00 P.M. (New York City time) on the Business Day specified in such notice.

(e) Assignments to Qualified Lenders. To the extent that a Non-Qualified Lender that has a risk participation in a Fronting Advance assigns all or part of its interest in such risk participation under Section 9.07 to a Qualified Lender, then (1) such assignee Lender shall make the amount of its assigned participation in such Fronting Advance available to the Administrative Agent for the account of the Fronting Bank, by deposit of such amount (in the applicable currency) to the Administrative Agent’s Account, in same day funds, not later than 1:00 P.M. (New York City time) on the third (3rd) Business Day following the effective date of the assignment and (2) such assignee shall continue to be treated hereunder as a Non-Qualified Lender for the sole purpose of computing the Fronting Fee on such Fronting Advance until such time as such assignee shall have made the deposit required under clause (1) above, provided that (A) such assignee shall not be deemed to be a Non-Qualified Lender for any other purpose and (B) the Fronting Bank shall have no obligation to make any Fronting Advances on behalf of such assignee.

(f) Failure to Make Payments. If any applicable Lender fails to make available to the Fronting Bank any amount required to be paid by such Lender pursuant to Section 2.03A(d) or 2.03A(e) by the time specified therein, the

7

Fronting Bank shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Fronting Bank at the Federal Funds Rate. A certificate of the Fronting Bank submitted to any applicable Lender (through the Administrative Agent) with respect to any amount owing under this Section 2.03A(f) shall be conclusive absent manifest error.

(g) Obligations Absolute. Each applicable Lender’s obligation to purchase and fund risk participations in Fronting Advances pursuant to this Section 2.03A shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Fronting Bank, any Loan Party or any other Person for any reason whatsoever, (2) the occurrence or continuance of a Default or Event of Default, or (3) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay the Fronting Bank, together with interest as provided herein.

(h) Funding of Risk Participations. At any time after any Lender has purchased and funded a risk participation in a Fronting Advance, if the Fronting Bank receives any payment on account of such Fronting Advance, the Fronting Bank will distribute to such Lender such payment (appropriately adjusted to reflect the period of time during which such Lender’s participation was funded) in the same funds and currency as those received by the Fronting Bank.

(i) Return of Payments. Notwithstanding the foregoing provisions of this Section 2.03A, if any payment referred to in Section 2.03A(h) is required to be returned by the Fronting Bank in connection with any proceeding under any Bankruptcy Law or otherwise (including pursuant to any settlement entered into by the Fronting Bank in its direction), the Lender to which the Fronting Bank paid such payment shall pay to the Fronting Bank in the applicable currency of such Fronting Advance the amount of such payment on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at the Federal Funds Rate. The Administrative Agent will make such demand upon the request of the Fronting Bank. The obligations of the applicable Lenders under this Section 2.03A(i) shall survive the payment in full of the Obligations of the Loan Parties under the Loan Documents and the termination of this Agreement.”

(j) Section 2.05(b) of the Credit Agreement is hereby amended by adding the following new clause (iii) thereto as follows:

“(iii) The Fronting Facility shall be permanently reduced from time to time on the date of each reduction in the Revolving Credit Facility by the amount, if any, by which the amount of the Fronting Facility exceeds the Revolving Credit Facility after giving effect to such reduction of the Revolving Credit Facility.”
