Ownership (a) Amount Beneficially Owned: The Issuer filed a Current Report on Form 8-K with the Securities and Exchange Commission ("SEC") 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"). The Reporting Persons believe that they may be deemed to have acquired beneficial ownership of in excess of 5% of the 6 Common Stock of the Issuer as of the Effective Date pursuant to the Plan in exchange for claims of the Reporting Persons against the Issuer and its subsidiaries. VII is a direct wholly owned subsidiary of Verizon and may be deemed to be the direct beneficial owner of shares of Common Stock of the Issuer. By virtue of their relationships, Verizon and VII may be deemed to have shared power to vote and dispose of, or to direct the vote and disposition of, the shares that may be deemed to be beneficially owned by VII. VGNI is a direct wholly owned subsidiary of Verizon and may be deemed to be the direct beneficial owner of shares of Common Stock of the Issuer. By virtue of their relationships, Verizon and VGNI may be deemed to have shared power to vote and dispose of, or to direct the vote and disposition of, the shares that may be deemed to be beneficially owned by VGNI. The responses of the Reporting Persons to Rows (9) and (10) of the cover pages of this Schedule 13G are incorporated herein by reference. VII estimates that as of the Effective Date VII may be deemed to beneficially own approximately 18,200 shares of Common Stock of the Issuer, which includes the right to acquire approximately 8,700 shares of Common Stock pursuant to warrants issued by the Issuer to VII pursuant to the Plan. The foregoing amount does not include any shares of Common Stock for which VII may be able to subscribe pursuant to nontransferable rights issued under the Plan and exercisable through the first business day after the 30th day after the Effective Date. VGNI estimates that as of the Effective Date VGNI may be deemed to beneficially own approximately 418,300 shares of Common Stock of the Issuer. As of the date hereof, the Reporting Persons have been only able to estimate the number of shares of Common Stock they may be deemed to beneficially own because the Reporting Persons have not yet received information sufficient to determine with precision the number of shares of Common Stock received or receivable pursuant to the Plan. Such number of shares cannot be finally determined until the actual amount of Allowed Claims (as defined in the Plan) has been finally determined by the Issuer. (b) Percent of Class: The responses of the Reporting Persons to Row (11) of the cover pages of this Schedule 13G are incorporated herein by reference. For purposes of calculating the percent of Common Stock that may be deemed to be beneficially owned, the Reporting Persons estimate that there were approximately 8,306,465 shares of Common Stock outstanding as of the Effective Date, based on information set forth in the Plan and in the Issuer's Form 8-K filed with the SEC on September 8, 2003. For purposes of such calculation for Verizon and VII, an additional 8,700 shares of Common Stock that VII has the right to acquire pursuant to warrants 7 that may be deemed to be beneficially owned by it, are to be deemed outstanding, in accordance with Rule 13d-3 under the Exchange Act. As of the date hereof, the Reporting Persons have been only able to estimate their percent of class that may be deemed to be beneficially owned because the Reporting Persons have not yet received information sufficient to determine with precision (i) the number of shares of Common Stock received or receivable pursuant to the Plan and (ii) the number of shares of Common Stock outstanding. Such numbers of shares cannot be finally determined until the actual amount of Allowed Claims (as defined in the Plan) has been finally determined by the Issuer. (c) Number of shares as to which such person has: (i) sole power to vote or to direct the vote, (ii) shared power to vote or to direct the vote, (iii) sole power to dispose or to direct the disposition, and (iv) shared power to dispose or to direct the disposition, in each case are incorporated by reference from the responses of the Reporting Persons to Rows (5) through (8) of the cover pages of this Schedule 13G and Item 4(a) hereof. Item 5. Ownership of Five Percent or Less of a Class: Not Applicable Item 6. Ownership of More Than Five Percent on Behalf of Another Person: Not Applicable. Item 7. Identification and Classification of the Subsidiary Which Acquired the Security Being Reported On by the Parent Holding Company: See Item 4. Item 8. Identification and Classification of Members of the Group: Not Applicable. Item 9. Notice of Dissolution of Group: Not Applicable. Item 10.
