SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. No material change. Item 4. PURPOSE OF TRANSACTION. This Item 4 is hereby amended by adding the following: On September 16, 2007, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with T-Mobile USA, Inc., a Delaware corporation and wholly owned subsidiary of Deutsche Telekom AG ("Parent"), and Tango Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Parent formed for the purpose of effecting the transactions contemplated by the Merger Agreement ("Merger Sub"), pursuant to which Parent will acquire all of the outstanding equity interests of the Company. Pursuant to the Merger Agreement, Merger Sub will be merged (the "Merger") with and into the Company with the Company surviving as a wholly owned subsidiary of Parent. At the effective time of the Merger, each outstanding share of common stock of the Company, other than shares owned by any stockholder who is entitled to and who properly exercises appraisal rights under Delaware law, will be cancelled and converted into the right to receive $27.00 in cash, without interest. Consummation of the Merger is not subject to a financing condition, but it is subject to certain conditions, including adoption of the Merger Agreement by the Company's stockholders, authorization by the Federal Communications Commission, the expiration or termination of any applicable review period by the Committee on Foreign Investment in the United State under the Exon-Florio Act if the parties file a voluntary notification, and the expiration or termination of the required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. The foregoing summary of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is referenced herein as Exhibit 8, and incorporated by reference in its entirety into this Item 4. In connection with the Merger Agreement, certain stockholders of the Company, including Highland Crusader Offshore Partners, L.P., Highland Credit Strategies Fund, L.P., Highland Capital Management Services, Inc., Highland CDO Opportunity Master Fund, L.P., Highland Credit Opportunities CDO, L.P., Highland Credit Opportunities CDO, Ltd., Highland Credit Strategies Master Fund, L.P., Highland Special Opportunities Holding Company, Restoration Opportunities Fund (collectively, the "Highland Entities"), and the Fund, entered into a Stockholder Voting Agreement with Parent and Merger Sub, dated as of September 16, 2007 (the "Voting Agreement"), pursuant to which they agreed to vote their shares in favor of the Merger and against any alternative proposal and to not sell, assign, transfer, pledge, encumber, or otherwise dispose of their shares of Class A Stock except to their respective affiliates or other signatories of the Voting Agreement, if certain conditions and requirements are satisfied. Under the Voting Agreement, the Highland Entities and the Fund may enter into any contract, option, swap or other agreement or arrangement, grant a participation in, and pledge and encumber the shares in connection with any bona fide lending, hedging or other financing or derivative transaction or arrangement, if certain conditions are met. If either the Company or Parent terminates the Merger Agreement before the Merger CUSIP NO. 86722Q108 PAGE 7 OF 9 is completed, the Voting Agreement will remain in effect for seven months and fifteen days following the termination of the Merger Agreement, except the Voting Agreement will terminate upon the termination of the Merger Agreement if (1) stockholder approval of the Merger has been obtained and remains in full force and effect at the time the Merger Agreement is terminated, (2) the Merger Agreement is terminated by mutual written consent of the Company and Parent, (3) the Merger is not consummated prior to July 16, 2008 (or, if regulatory approvals have not been obtained on such date, September 16, 2008) (the "End Date"), (4) the Merger Agreement is terminated by either the Company or Parent by reason of the issuance of an order by any governmental authority that permanently enjoins or prohibits the consummation of the Merger, (5) the Merger Agreement is terminated by either the Company or Parent by reason of the enactment or enforcement of a statute or order that has the effect of making certain conditions to the Merger incapable of being satisfied prior to the End Date, (6) the Merger Agreement is terminated by the Company by reason of Parent's or Merger Sub's breach or failure to perform their representations, warranties, covenants or other agreements, which breach or failure to perform would cause the failure of certain conditions to the Merger, or (7) the Merger Agreement is terminated by the Parent by reason of the Company's non-willful breach or failure to perform its representations, warranties, covenants or other agreements, which breach or failure to perform would cause the failure of certain conditions to the Merger. This summary of the Voting Agreement does not purport to be complete and is qualified in its entirety by reference to the Voting Agreement, which is referenced herein as Exhibit 9 and incorporated by reference in its entirety into this Item 4. The Merger Agreement and the transactions contemplated thereby could result in one or more of the actions specified in clauses (a)-(j) of Item 4 of Schedule 13D, including the acquisition or disposition of additional securities of the Company, a merger or other extraordinary transaction involving the Company, a change to the present board of directors of the Company and a change to the present capitalization or dividend policy of the Company. One or more of the Reporting Persons are expected to take actions in furtherance of the Merger Agreement (including any amendment thereof) and the transactions contemplated thereby.
