Cash and notes make up the balance of the consideration for the cancellation of the above referenced debt as described in Item 4 below. The Issuer has not yet issued the shares of Common Stock or the notes nor distributed the cash amounts, to be issued and distributed to Matlin Partners (Delaware) and Matlin Partners (Bermuda) as consideration for the cancellation of the debt obligations of the Issuer as described in this Item 3 but will do so as soon as practicable. The Reporting Persons paid cash from working capital for the cancelled debt instruments. No funds were borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting the Common Stock. Item 4. Purpose of Transaction Pursuant to the Plan, the Reporting Persons have received or will receive, as soon as practicable and in accordance with the documents executed in connection with the Plan, as consideration for the cancellation of debt obligations acquired through open market purchases and having an approximate principal amount of $1.2 billion approximately, (i) 20,320,808 shares of Common Stock, (ii) notes of the reorganized Issuer for an aggregate principal amount of $101,604,039 (unless substituted with cash as contemplated under the Plan), and (iii) cash for an amount of $79,787,287 (or $181,391,326 in the event cash is paid in lieu of the notes identified in (ii)), in each case, subject to adjustments pursuant to the Plan's reallocation procedures and treatment of disputed claims (each described below). The shares of Common Stock to be acquired by the Reporting Persons pursuant to the Plan represent, in the aggregate, approximately 20.3% of the shares of Common Stock of the reorganized Issuer, subject to adjustments pursuant to the Plan's reallocation procedures and treatment of disputed claims (each described below). Pursuant to the reallocation procedures set forth in Article V of the Plan, each creditor in Classes 5 and 6 was eligible to elect to contribute (i) all of their shares of Common Stock in the reorganized Issuer at the standard rate of $22.25 per share or at a lower price per share (ranging from $16.00 to $22.00 in 1/4 point intervals), and/or (ii) all or a portion (ranging from 0% to 100%) of the notes and cash to be distributed to such creditor under the Plan. The reallocation is to be effectuated "dutch auction" style first by exchanging those shares of Common Stock offered into the reallocation pool for cash starting at the lowest price per share selected until all of the cash or the shares of Common Stock in the reallocation pool is exhausted. Next, any remaining shares of Common Stock would be exchanged for notes, again starting at the lowest price per share selected until all of the notes or shares of Common Stock are exhausted. The result is that the distribution to each participating creditor, including the Reporting Persons, of Common Stock, cash and notes may change after giving effect to the outcome of the reallocation procedure. The cash portion of the consideration is to be paid through a combination of the reorganized Issuer's cash on hand and Xcel Energy Inc.'s ("Xcel") contribution of the "release-based" cash amount. The release-based cash amount is to be paid out over time as it is received by the reorganized Issuer from Xcel, pursuant to the terms of that certain Settlement Agreement (Page 13 of 20) with Xcel entered into as part of the Plan. The first and second installments of $200 million in the aggregate is due to be paid by Xcel 90 days after the date on which the Bankruptcy Court entered the order confirming the Issuer's Plan. The third installment is to be paid on April 30, 2004, unless extended pursuant to the terms of the Settlement Agreement. Under certain circumstances specified under the Settlement Agreement, a portion of the Xcel contribution described above can be made with shares of Xcel common stock (NYSE: XEL), which, pursuant to Section 8.7 of the Plan, can be liquidated by the reorganized Issuer and the proceeds thereof distributed to Class 5 creditors. In addition, the Reporting Persons would be entitled to receive their pro rata portion of up to an additional $150 million of cash that, subject to the satisfaction of certain conditions, may be available for distribution under the Plan. Pursuant to Article X of the Plan, the Issuer and certain of its affiliates shall establish a disputed claims reserve to be funded with the appropriate number of shares, notes and cash for distribution to holders of disputed claims that subsequently become allowed by the Bankruptcy Court. Distributions from the disputed claims reserve will be made on a quarterly basis to holders of disputed claims that have become allowed. The Reporting Persons' percentage ownership may vary depending on whether the amount of disputed claims ultimately allowed is greater or less than the amount reserved. On December 5, 2003 and in accordance with Section 8.2(b) of the provisions of the Plan, three representatives of the Reporting Persons became directors of the reorganized Issuer. Section 8.2(b) of the Plan provides, in pertinent part, that the "board of directors for Reorganized NRG shall consist of the post-reorganization CEO and ten (10) individuals, of which six (6) directors shall be designated by the members of the Noteholder Group serving on the Committee...", which includes the Reporting Persons.
