WHEREAS, the Borrower has requested that the Administrative Agent and the Lenders amend the definition of “Consolidated EBITDA” in Section 1.1 of the Reimbursement Agreement to address non-cash losses and non-cash gains as set forth herein, and the Administrative Agent and the Lenders party hereto are willing to amend such definition as set forth herein.

NOW THEREFORE, in consideration of the foregoing and the mutual agreements set forth herein, the parties agree as follows:

Section 1. Definitions. Unless otherwise defined in this Amendment, each capitalized term used in this Amendment has the meaning assigned to such term in the Reimbursement Agreement.

Section 2. Amendment to Reimbursement Agreement. The Reimbursement Agreement is hereby amended as follows:

(a) The definition of “Consolidated EBITDA” in Section 1.1 of the Reimbursement Agreement is hereby amended as follows:

“ “Consolidated EBITDA” means, with respect to the Borrower and its Subsidiaries for any fiscal period, the sum of (a) operating income from continuing operations and from discontinued operations (but expressly excluding any extraordinary gains and extraordinary losses), (b) depreciation and amortization expense, (c) net unrealized losses under any derivatives (to the extent such amounts are included in operating income), (d) impairments of utility plant (to the extent such amounts are included in operating income), (e) impairments of regulatory assets and regulatory disallowances (to the extent such amounts are included in operating income) and (f) other charges, losses or writedowns that do not represent a cash item in such period or any future period (to the extent such amounts are included in operating income), less (g) net unrealized gains under any derivatives and other gains that do not represent a cash item in such period or any future period (to the extent such amounts are included in operating income), in each case, determined in accordance with GAAP and consistent with the preparation and presentation of the Borrower’s financial statements delivered pursuant to Section 4.1(d). For illustrative purposes, Schedule 1.1(b) sets forth a calculation of Consolidated EBITDA for the period ended March 31, 2008, in accordance with the foregoing.”

(b) The Reimbursement Agreement is hereby amended by (i) deleting the existing Schedule 1.1(b) to the Reimbursement Agreement and inserting in its place the text contained in Attachment 1 attached to this Amendment as the new Schedule 1.1(b) to the Reimbursement Agreement and (ii) making the corresponding changes to Section B to Schedule 1 to Exhibit 7.1(c).

(c) The Borrower shall have confirmed and acknowledged to the Administrative Agent and the Lenders, and by its execution and delivery of this Amendment the Borrower does hereby confirm and acknowledge to the Administrative Agent and the Lenders, that (i) the execution, delivery and performance of this Amendment has been duly authorized by all requisite corporate action on the part of the Borrower; (ii) the Reimbursement Agreement and each other Credit Document to which it is a party constitute valid and legally binding agreements enforceable against the Borrower in accordance with their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws relating to or affecting the enforcement of creditors’ rights generally and by general principles of equity; (iii) the representations and warranties by the Borrower contained in the Reimbursement Agreement and in the other Credit Documents are true and correct on and as of the date hereof in all material respects as though made as of the date hereof, except to the extent they expressly and exclusively relate to an earlier date; and (iv) no Default or Event of Default exists under the Reimbursement Agreement or any of the other Credit Documents.
