Item 3.	Source and Amount of Funds or Other Consideration
See Item 4.
Fiber acquired the securities with approximately $25 million of working capital contributed by Mr. McCaw through COM Holdings.

Item 4.	Purpose of Transaction
The Issuer filed a Current Report on Form 8-K filed with the Securities and Exchange Commission (“Commission”) on September 8, 2003 in which it reported that it had emerged from Chapter 11 of the U.S. Bankruptcy Code on September 8,2003 (the “Effective Date”), pursuant to the Issuer’s Second Amended Plan of Reorganization (the “Plan”). According to the Issuer, pursuant to its Plan, all previously existing equity securities of the Issuer were cancelled on the “Effective Date. All capitalized terms used in this statement and not herein defined have the meanings ascribed to them in the Plan, a copy of which is filed as Exhibit 2.1 to the Issuer’s Current Report on Form 8-K filed with the Commission on September 4, 2003. The Plan requires that shares of Common Stock be issued to holders of Allowed Claims. However, according to the Issuer, the allocation of those shares and warrants among the holders of Allowed Claims cannot be finally determined until the actual amount of Allowed Claims is finally determined. Pending final resolution of all claims, the Issuer will make interim distributions of a portion of the securities to be distributed under the Plan. The securities indicated in this statement reflects the Reporting Persons’ best estimates of the securities to be distributed to the Reporting Persons in respect of their Allowed Claims. Pending a final determination of the shares of Common Stock to be issued to the holders of Allowed Claims under the Plan, the remaining securities to be distributed under the Plan are being held by the Issuer.
Pursuant to the Plan and the Order dated August 21, 2003 confirming the Plan (the “Order”), a copy of which was filed as Exhibit 2.4 to the Issuer’s Current Report on Form 8-K filed with the Commission on September 4, 2003, the Issuer is conducting an offering of Rights (the “Rights”) exercisable for shares of Common Stock (the “Rights Shares”) to certain holders of Allowed Claims. The number of Rights Shares to be acquired by the Reporting Persons is presently unknown. In accordance with the Plan and the Order, Fiber is entitled to exercise up to a minimum of 417,303 of the Rights Shares (the “Fiber Rights Shares”). In the event that certain Rights are unexercised by certain other holders of Allowed Claims, then Fiber may be required to exercise additional Rights up to an aggregate, inclusive of any Fiber Rights Shares acquired, of 834,605 Rights Shares (the “Excess Rights Shares”) under the Plan and Order. The total number of Rights Shares Fiber may exercise under the Plan and Order depending upon the amount of Rights exercised by other participants, inclusive of the Fiber Rights Shares and Excess Rights Shares, is 1,669,210.
From time to time, one or more of the Reporting Persons may seek to increase, reduce or dispose of their investment in the Issuer in the open market, in privately negotiated transactions, or otherwise. The determination to effect any such transactions will depend

on, among other things, the market price, availability of funds, borrowing costs, market conditions, tax considerations, developments affecting the Issuer and the Reporting Persons, other opportunities available to the Reporting Persons and other considerations.
Except as set forth above, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions required to be described in Item 4 of Schedule 13D. Each of the Reporting Persons may, at any time, review or reconsider its position with respect to any of such matters, but has no present intention of doing so.
