Item 3 is hereby amended by adding the following immediately after the last paragraph thereof: On March 7, 2003, the Company completed the Restructuring contemplated in the Lock-Up Agreement entered into on October 17, 2002. In the Restructuring, AIF IV and Overseas IV acquired (i) 52,581,285 shares of Common Stock, in exchange for $46.5 million, principal amount at maturity, senior secured discount notes of the Company, and $16.9 million, principal amount at maturity, senior secured notes of the Company, (ii) (a) 39,927,796 shares of Common Stock, and (b) warrants to purchase an additional 45,416,690 shares of Common Stock, with 27,250,013 warrants having an exercise price of $1.04 per share ("Series A Warrants") and 18,166,677 warrants having an exercise price of $.92 per share ("Series B Warrants" and together with Series A Warrants, "New Warrants"), in exchange for all of the shares of Preferred Stock held by them, and (iii) 24,060,271 shares of Common Stock in exchange for an investment by AIF IV of $23,727,500 in cash and by Overseas IV of $1,272,500 in cash. The cash investments were funded from capital contributions (in the ordinary course) from AIF IV's and Overseas IV's respective limited partners. The Reporting Persons expressly disclaim beneficial ownership of any shares of Common Stock held by, or to be acquired (whether in the Restructuring or otherwise) by, any other party to the Restructuring, or any of their affiliates. The Reporting Persons further disclaim any group status with any other such persons or parties to the Restructuring. ITEM 4. PURPOSE OF TRANSACTION. Item 4 is hereby amended by the incorporation by reference herein of the matters set forth in Item 3. The Restructuring resulted in several of the actions or events in clauses (a) through (j) of Item 4 of Schedule 13D including clauses (a), (d), (e), and (g). Except as set forth in this Item 4, AIF IV and Overseas IV have no plans or proposals that relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. Notwithstanding the foregoing, the Reporting Persons retain the right to change their investment intent, to propose one or more possible transactions to the Company's Board, to acquire additional shares of Common Stock from time to time or to sell or otherwise dispose of all or part of the Common Stock beneficially owned by them in any manner permitted by law. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (a) As a result of the Restructuring, the Reporting Persons beneficially own 162,986,042 shares of Common Stock, including 45,416,690 shares purchasable upon the exercise of currently exercisable New Warrants, representing 17.03% of the currently outstanding shares of Common Stock assuming the exercise of all of the New Warrants. The shares of Common Stock subject to the New Warrants represent 4.75% of the currently outstanding shares of Common Stock, assuming the exercise of all of the New Warrants. See also the information contained on the cover pages to this Schedule 13D, which is incorporated herein by reference. (b) See the information contained on the cover pages to this Schedule 13D, which is incorporated herein by reference. For purposes of Section 13 of the Act, Advisors IV may be deemed to control AIFIV and Overseas IV, respectively. Each of the Reporting Persons may thus be considered to beneficially own and to have sole voting and dispositive power with respect to all of the Common Stock of the Issuer to be held of record by AIFIV and Overseas IV. (c) There have been no reportable transactions with respect to the Common Stock of the Issuer within the last 60 days by the Reporting Persons. (d) Not applicable. (e) Not applicable. ITEM 6.
