PRELIMINARY STATEMENT

The Requisite Lenders and the Borrower have agreed, subject to the terms and conditions of this Amendment, to amend the Credit Agreement as hereinafter set forth.

STATEMENT OF AGREEMENT

SECTION 1.  Amendment to Credit Agreement.  The Credit Agreement is, effective as of the date hereof and subject to the satisfaction of the conditions precedent set forth in Section 2 hereof, hereby amended as follows:

(a)                                  The definition of “Revolving Loan Commitment Termination Date” is amended by deleting clause (A) thereof in its entirety and substituting therefor the following:

“(A) May 1, 2008,”

(b)                                 Section 3.03(b) of the Credit Agreement is amended by deleting it in its entirety and substituting therefor the following:

“(b)                           Apportionment of Payments.

(i)                                     Subject to the provisions of Section 3.03(b)(ii), all payments of principal and interest in respect of outstanding Revolving Loans shall be applied by the Administrative Agent to the ratable payment of the Revolving Loans owing to the Lenders in accordance with their respective Pro Rata Shares thereof.

(ii)                                  After the occurrence of an Event of Default and while the same is continuing, the Administrative Agent shall apply all payments and prepayments of any Obligations in the following order (without duplication):

(A)                              first, to pay all principal of and interest on any Revolving Loans which the Administrative Agent may have advanced on behalf of any Lender pursuant to Section 2.01(c)(ii) for which the Administrative Agent has not been reimbursed by such Lender or the Borrower;

(B)                                second, to pay all Obligations in respect of any fees, expense reimbursements or indemnities then due to the Agents (solely in their capacity as Agents);

(C)                                third, to pay all Obligations in respect of any expense reimbursements or indemnities then due to any Lender;

(D)                               fourth, to pay all Obligations consisting of accrued fees and interest then due; and

(E)                                 fifth, to pay all other Obligations then outstanding and due (including, without limitation, all outstanding principal thereof and all outstanding Reimbursement Obligations), and thereafter, solely to the extent then required by the Agent and the Requisite Lenders, to the cash collateralization of any remaining outstanding Letter of Credit Obligations.

The order of priority set forth in this Section 3.03(b)(ii) and the related provisions of this Agreement are set forth solely to determine the rights and priorities of the Administrative Agent and the Lenders as among themselves.  In carrying out the foregoing, each of the Lenders (including the Issuing Bank, for this purpose) shall receive an amount equal to its pro rata share (based on the proportion that the amount of the relevant Obligations held by such Lender bears to the aggregate amount of the relevant Obligations held by all Lenders) of amounts available to be applied pursuant to clauses (C) through (E) above.  If sufficient funds are not available to fund all Obligations described in any of the foregoing clauses (A) through (E), the available funds shall be allocated to the Obligations described in such clause ratably as provided herein.”
