3

Advances (expressed in Dollars and including the Equivalent in Dollars at such time of any amounts denominated in a Committed Foreign Currency) plus the Available Amount of all outstanding Multicurrency Letters of Credit (expressed in Dollars and including the Equivalent in Dollars at such time of any amounts denominated in a Committed Foreign Currency) at such time exceed the Multicurrency Revolving Credit Commitments at such time. The Reallocation Notice shall (x) specify (1) the proposed aggregate amount of such Reallocation (the “Total Reallocation Amount”), (2) the Facility being increased (the “Increasing Facility”), (3) the Facility being decreased (the “Decreasing Facility”), and (4) the proposed Reallocation Date and (y) contain a certification signed by a Responsible Officer of the Borrower stating that all of the requirements set forth in this Section 2.19(a) have been satisfied or, as of the Reallocation Date, will be satisfied.

(b) Upon receipt of any Reallocation Notice, the Administrative Agent shall promptly deliver a copy of such Reallocation Notice to each Issuing Bank and each Lender and notify each Lender of its proposed proportionate share of (i) the Decreasing Facility, (ii) the Increasing Facility, and (iii) the Total Reallocation Amount. Such determinations shall be made by the Administrative Agent for each Lender within each Facility based on the ratio of the Commitment of such Lender in respect of such Facility to the total Commitments of all Lenders in respect of such Facility, and (iv) the date by which Lenders with increasing Commitments, if any, resulting from such Reallocation must commit in writing to the increase in their respective Commitments (the “Reallocation Commitment Date”). Each Lender that is willing to participate in such Commitment increase resulting from the Reallocation (each, an “Increasing Reallocation Lender”) shall, in its sole discretion, give written notice to the Administrative Agent on or prior to the Reallocation Commitment Date of the amount by which it is willing to increase its applicable Commitment (an “Increased Commitment Amount”). If any Lender in the Increasing Facility shall fail to provide such notice or shall decline, in whole or in part, to commit to its allocable share of the Commitment increase, then the Administrative Agent shall promptly offer such share to other Increasing Reallocation Lenders on a pro rata basis. Each Issuing Bank shall confirm in writing its approval of the Reallocation.

(c) Promptly following the Reallocation Commitment Date, the Administrative Agent shall notify the Borrower of any shortfall in the Commitments allocable to the Increasing Facility. In the event of any such shortfall, the provisions of Sections 2.18(c) and 2.18(d) shall apply, mutatis mutandis.

(d) On the applicable Reallocation Date, (i) the Reallocation shall be effected by reallocating Commitments from the Decreasing Facility to the Increasing Facility on a dollar-for-dollar basis, and (ii) to the extent Advances then outstanding and owed to any U.S. Dollar Revolving Lender or any Multicurrency Revolving Lender immediately prior to the effectiveness of the Reallocation shall be less than such Lender’s U.S. Dollar Revolving Credit Pro Rata Share or Multicurrency Revolving Credit Pro Rata Share (calculated immediately following the effectiveness of such Reallocation) of all Advances then outstanding that are owed to U.S. Dollar Revolving Lenders or to Multicurrency Revolving Lenders (collectively, including any applicable Assuming Lender, the “Purchasing Lenders”), in each case as applicable, then such Purchasing Lenders, without executing an Assignment and Acceptance, shall be deemed to have purchased an assignment of a pro rata portion of the Advances then outstanding and owed to each Lender that is not a Purchasing Lender (collectively, the “Selling Lenders”), in an amount sufficient such that following the effectiveness of all such assignments (x) the Advances outstanding and owed to each U.S. Dollar Revolving

4

Lender shall equal such Lender’s U.S. Dollar Revolving Credit Pro Rata Share (calculated immediately following the effectiveness of the Reallocation) of all Advances then outstanding in respect of the U.S. Dollar Revolving Credit Facility and (y) the Advances outstanding and owed to each Multicurrency Revolving Lender shall equal such Lender’s Multicurrency Revolving Credit Pro Rata Share (calculated immediately following the effectiveness of the Reallocation) of all Advances then outstanding in respect of the Multicurrency Revolving Credit Facility. The Administrative Agent shall calculate the net amount to be paid by each Purchasing Lender and received by each Selling Lender in connection with the assignments effected hereunder on the Reallocation Date. Each Purchasing Lender shall make the amount of its required payment available to the Administrative Agent, in same day funds, at the office of the Administrative Agent not later than 12:00 P.M. (New York time) on the Reallocation Date. The Administrative Agent shall distribute on the Reallocation Date the proceeds of such amount to each of the Selling Lenders entitled to receive such payments at its Applicable Lending Office.

(e) On the Reallocation Date, the Letter of Credit Commitments shall, subject to the provisions of this Section 2.19(e), be reallocated between the U.S. Dollar Letter of Credit Facility and the Multicurrency Letter of Credit Facility in a manner proportionate to the Reallocation of Revolving Credit Commitments from the Decreasing Facility to the Increasing Facility. Upon the effectiveness of such reallocation, (i) the U.S. Dollar Letter of Credit Commitment shall be an amount equal to the aggregate amount of the Letter of Credit Commitments multiplied by the quotient obtained by dividing the U.S. Dollar Revolving Credit Commitments (as in effect immediately following the Reallocation) by the aggregate Revolving Credit Commitments, and (ii) the Multicurrency Letter of Credit Commitment shall be an amount equal to the aggregate amount of the Letter of Credit Commitments less the amount of the U.S. Dollar Letter of Credit Commitment established pursuant to the preceding clause (i); provided, however, that such reallocation of the Letter of Credit Commitments shall be made only to the extent that following the effectiveness thereof (x) the sum of all Letter of Credit Advances then outstanding in respect of U.S. Dollar Letters of Credit plus the Available Amount of all U.S. Dollar Letters of Credit shall not exceed the U.S. Dollar Letter of Credit Commitment, and (y) the sum of all Letter of Credit Advances then outstanding in respect of Multicurrency Letters of Credit plus the Available Amount of all Multicurrency Letters of Credit shall not exceed the Multicurrency Letter of Credit Commitment.

(f) On the Reallocation Date, the Borrower shall execute and deliver a replacement Note payable to the order of each Lender requesting the same in a principal amount equal to such Lender’s respective Revolving Credit Commitment immediately following the effectiveness of the Reallocation. Each Lender receiving a replacement Note shall promptly return to the Borrower any previously issued Note for which such replacement Note was delivered in exchange.

(g) On the Reallocation Date, the Administrative Agent shall notify the Lenders and the Borrower, on or before 1:00 P.M. (New York City time), by telecopier, telex or other electronic mail communication, of the occurrence of the Reallocation to be effected on such Reallocation Date and shall promptly distribute to the Lenders and the Borrower a copy of Schedule I hereto revised to reflect such Reallocation. The Administrative Agent shall record in the Register the relevant information with respect to each Lender on such Reallocation Date in accordance with Section 9.07.”
