(the "ISSUER"). This Statement supplementally amends the initial statement on Schedule 13D, filed on March 28, 2002 (the "INITIAL STATEMENT"), by Sandler Capital Partners V, L.P., a Delaware limited partnership, Sandler Capital Partners V FTE, L.P., a Delaware limited partnership, Sandler Capital Partners V Germany, L.P., a Delaware limited partnership, Sandler Investment Partners, L.P., a Delaware limited partnership and Sandler Capital Management, a New York general partnership (collectively, the "REPORTING PERSONS"). In September 2004, the Reporting Persons exchanged, on a share-for-share basis, all of the Series B Convertible Preferred Stock of the Issuer held by them for Series C Convertible Preferred Stock of the Issuer (the "SERIES C PREFERRED STOCK"). This Amendment No. 1 is being filed to report that the Reporting Persons have entered into an agreement with the Issuer with respect to the allocation of any transaction consideration between all of the holders (the "SERIES C PREFERRED HOLDERS") of the Series C Preferred Stock (including the Reporting Persons) and the holders of Common Stock, in order to resolve any allocation issues in advance of any potential sale of the Issuer. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIP WITH RESPECT TO THE ISSUER. On July 11, 2006, the Issuer entered into an Agreement (the "Agreement") with the Series C Preferred Holders, including the Reporting Persons, relating to the allocation of transaction consideration between Series C Preferred Holders and the holders of the Common Stock (the "COMMON STOCK HOLDERS") , in the event of a sale of the Issuer. The Agreement sets forth the agreement of the Series C Preferred Holders to an allocation of net proceeds available for distribution to the Series C Preferred Holders and the Common Stock Holders in the event of a sale of the Issuer in which the net cash proceeds available for distribution to the Series C Preferred Holders and the Common Stock Holders equals or exceeds $105 million, notwithstanding that the terms of the Series C Preferred Stock may otherwise entitle the Series C Preferred Holders to a greater portion of such proceeds. The Agreement provides for the allocation to the Common Stock Holders of 12.75% of the first $135 million of net proceeds (with a minimum allocation to the Common Stock of at least $14 million), 15% of any additional net proceeds up to $145 million, 25% of any additional net proceeds up to $185 million and 20% of any additional net proceeds over $185 million. In the Agreement, the Series C Preferred Holders have further agreed to vote in favor of, and to provide certain other consents and waivers (all such obligations together, the "Consents") to facilitate, a sale transaction entered into by the Issuer that yields aggregate net cash proceeds to the Common Stock Holders and Series C Preferred Stock equal to or greater than $105 million. The Agreement does not obligate the Series C Preferred Holders to provide the Consents if a sale transaction entered into by the Issuer yields aggregate net cash proceeds to the Common Stock Holders and Series C Preferred Holders of less than $105 million. The Agreement provides that it may be terminated by the Series C Preferred Holders or by the Issuer if an agreement for a sale of the Issuer has not been signed on or before February 1, 2007. Except for the agreements described in response to this Item 6 or in response to Items 3 and 4 of the Initial Statement, which are hereby incorporated herein by reference, to the best knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons, and any other person, with respect to any securities of the Issuer, including, but not limited to, transfer or voting of any of the securities, finder's fees, joint ventures, loan or option agreements, puts or calls, guarantees of profits, divisions of profits or loss, or the giving or withholding of proxies. The Reporting ----------------------------- ---------------------------- 709668 10 7 Page 8 of 10 Persons disclaim membership in any group, including any group with any holders of Series C Preferred Stock other than the Reporting Persons. ----------------------------- ---------------------------- 709668 10 7 Page 9 of 10 SIGNATURES After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
