AES Eastern Energy Enters Non-Binding Term Sheet for Asset Sale

The parties to this Term Sheet are AES Eastern Energy, L.P., AES Somerset, LLC, AES Cayuga, LLC, AES NY3, LLC, and, to the extent applicable, Somerset Railroad Corporation (“SRC” and, collectively with the preceding entities, “AEE”), the undersigned members of the Ad Hoc Committee of Pass-Through Certificate Holders (the “Holders”), and Deutsche Bank Trust Company Americas, as indenture trustees (the “Trustee” and, together with the foregoing parties, the “Parties”).

The Parties will settle a series of disputes and potential disputes (such settlement pursuant to the terms herein, the “Settlement”) on various issues regarding the transactions attending the 1999 acquisition of the Somerset and Cayuga generating stations (the “1999 Transaction”) in order to preserve going-concern value, conserve assets of the estates for the benefit of all creditors, and effectuate an efficient transfer of the Somerset and Cayuga facilities and related assets (the “Transferred Assets”) to an entity designated by the Holders (“Newco”), subject to higher and better offers in an auction process.

The several terms of the Settlement shall each constitute necessary elements of a single, fully integrated settlement, and the approval of all of the terms herein shall be a condition of consummating the Settlement and Sale Transaction. If any of the terms herein are not approved by the Bankruptcy Court in the Cases and such approval requirement is not waived by AEE and the Trustee, the Parties shall be restored to the status quo ante as it existed prior to the execution of this Term Sheet, and all of the Parties’ respective rights, claims, interests, arguments, and defenses shall be fully preserved.

The Settlement and any implementing transactions will be effectuated in chapter 11 cases (the “Cases”) to be filed on or about December 30, 2011 (the “Petition Date”) by AEE and related debtors.

Solely for purposes of the Settlement, the Parties stipulate that the obligations arising from the 1999 Transaction shall be treated as a secured financing as of the Petition Date, with the Trustee holding and controlling an allowed claim in the amount of $600,000,000, secured by the Adequate Protection Liens (as defined below) and the Trustee’s existing valid and perfected first priority security interests in and liens on the Transferred Facilities and other assets comprising the Indenture Estate (as defined in the documents evidencing the 1999 Transaction) (the “Secured Claim”).

AEE and the Holders shall enter into an asset purchase agreement providing for the acquisition of the Transferred Assets by Newco free and clear of any claims or interests pursuant to section 363(b) and (f) of the Bankruptcy Code. Newco will be a stalking horse bidder with a purchase price equal to the sum of (a) a credit bid of $300,000,000 (which may include the value of any Adequate Protection Liens (as defined below), which the Trustee shall have the right to credit bid); (b) the value of the Assumed Liabilities; (c) cash in the amount of $5,000,000 (the “Cash Payment”), provided, however, that the Cash Payment may be reduced or increased by the Coal/AR Adjustment (defined below); (d) any remaining cash in the Deutsche Bank Depository Accounts as of the closing of the Sale Transaction; and (e) to the extent the transfer date does not occur on or prior to March 30, 2012, additional cash consideration equal to the operating losses, if any, of the Transferred Assets for the period from April 1, 2012 to the transfer date, which shall include AEE overhead at a market rate to be agreed upon by the Parties but not restructuring costs for such period (collectively, the “Purchase Price”). The Cash Payment will be adjusted (the “Coal/AR Adjustment”) by the difference between (i) the value as of the closing of the Sale Transaction of (x) coal either located at the Somerset and Cayuga facilities or paid for by AEE and not yet delivered and (y) accounts receivable related to the operations of AES Eastern Energy, L.P. and (ii) the Minimum Coal/AR Balance (defined below).

The Trustee shall have an allowed general unsecured claim (such claim, the “Residual Claim”) against AES Eastern Energy, L.P. in the amount of $300,000,000, less the amount by which the proceeds realized through a Third Party Sale (defined below) exceed the Purchase Price. In the event that the amount of the credit bid is increased at a later date, the amount of the Residual Claim will be reduced on a dollar-for-dollar basis.

The definitive documents implementing the Sale Transaction shall have representations, warranties, covenants, and conditions customary for sale transactions consummated pursuant to Bankruptcy Code section 363(b) and (f), including, without limitation, a covenant that, until the closing of the Sale Transaction or a Third Party Sale (as defined below), AEE shall operate the Somerset and Cayuga facilities and any related assets in the ordinary course of business, in a manner consistent with past practices, and in accordance with a budget reasonably acceptable to the Trustee, subject to available liquidity and AEE’s fiduciary obligations.

In the event Newco is the not the successful bidder in any sale of any of the Transferred Assets, the entirety of the proceeds of any such sale (a “Third Party Sale”), to the extent the proceeds relate to the Transferred Facilities, shall be applied at closing of such Third Party Sale to repay the Trustee’s claims arising from the 1999 Transaction.

The Settlement and Sale Transaction shall be subject to all necessary approvals of the Bankruptcy Court and any applicable governmental regulatory authorities.
