WHEREAS, Sprint and the Company are parties to an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), whereby a wholly owned subsidiary of Sprint will merge with and into the Company (the “Merger”), with the result that the Company will become a wholly owned subsidiary of Sprint (capitalized terms used herein but not otherwise defined shall have the meanings set forth in the Merger Agreement);

WHEREAS, each Stockholder is, except as otherwise noted on Schedule A hereto (the shares of Common Stock referred to on Schedule A are referred to herein as the “Schedule A Shares”), the sole beneficial owner (and holds sole beneficial voting power) of the shares of common stock of the Company, par value $0.01 per share (“Common Stock”), set forth opposite such Stockholder’s name on Schedule B hereto (all of the shares owned by the Stockholders as of the date hereof being hereinafter referred to as the “Existing Shares” and, together with any shares of Common Stock or other shares of capital stock of the Company acquired by the Stockholders after the date hereof, as the “Shares”); and

WHEREAS, as a condition and inducement to Sprint’s willingness to enter into the Merger Agreement, each Stockholder has agreed to vote all of its Shares pursuant to the terms and conditions of this Agreement and to certain other matters set forth herein.

NOW, THEREFORE, in consideration of the foregoing and in consideration of the mutual covenants and agreements contained herein and intending to be legally bound, the parties agree as follows:

1. Voting of Shares. During the Proxy Term (as defined below), each Stockholder hereby agrees that at any annual, special or other meeting of the stockholders of the Company, and at any adjournment or adjournments thereof, and in connection with any action of the stockholders of the Company taken by written consent, such Stockholder will:

(a) appear in person or by proxy at each such meeting or otherwise cause the Shares beneficially owned by such Stockholder (other than the Schedule A Shares) to be counted as present at such meeting for purposes of calculating a quorum; and

(b) unless Sprint votes such Stockholder’s Shares directly pursuant to the proxy granted in Section 2 hereof, (i) vote (or cause to be voted) its Shares (other than the Schedule A Shares), in person or by proxy, in favor of adopting the Merger Agreement, approving the Merger and any other action of the stockholders of the Company reasonably

requested by Sprint in furtherance thereof; and (ii) vote (or cause to be voted) its Shares (other than the Schedule A Shares), in person or by proxy, against, and not deliver any written consent with respect to such Shares in favor of, any other Acquisition Proposal submitted for approval to the stockholders of the Company, unless Sprint consents in writing to such Stockholder voting in favor of, or delivering a consent with respect to, such other Acquisition Proposal.

(a) Each Stockholder by this Agreement does hereby constitute and appoint Sprint, or any nominee of Sprint, with full power of substitution, during and for the Proxy Term, as such Stockholder’s true and lawful attorney and irrevocable proxy, for and in such Stockholder’s name, place and stead, to vote the Shares of such Stockholder (other than the Schedule A Shares) as such Stockholder’s proxy, at every meeting of the Company’s stockholders or any adjournment thereof (or, as applicable, to instruct and direct any holder of record of such Shares to vote such Shares) or execute its proxy with respect to such Shares at every meeting of the Company’s stockholders or any adjournment thereof, in favor of approving the Merger Agreement, the Merger and any other action of the Company’s stockholders reasonably requested by Sprint in furtherance thereof; and against any other Acquisition Proposal submitted for approval to the Company’s stockholders unless Sprint and such Stockholder determine to vote or consent in favor of such other Acquisition Proposal. Each Stockholder intends this proxy to be irrevocable and coupled with an interest during the Proxy Term and hereby revokes any proxy previously granted by such Stockholder with respect to its Shares (except as may be otherwise noted on Exhibit A). Each Stockholder acknowledges that, pursuant to the authority hereby granted under the irrevocable proxy, Sprint may vote such Stockholder’s Shares in furtherance of its own interests, and Sprint is not acting as a fiduciary for such Stockholder.

(b) For purposes of this Agreement, “Proxy Term” means the period from the execution of this Agreement until the termination of this Agreement in accordance with the terms of Section 9(a) hereof.

(c) Each Stockholder agrees that the irrevocable proxy set forth in this Section 2 hereof shall not be terminated by any act of such Stockholder or by operation of law, other than upon expiration of the Proxy Term.

(a) Promptly following the date hereof, the Stockholders shall deliver written instructions to the Company and to the Company’s transfer agent stating that the Shares (other than the Schedule A Shares) may not be Transferred (as defined below) in any manner during the term of this Agreement without the prior written consent of Sprint or except as provided in this Agreement.

(b) Promptly following the date hereof, each Stockholder shall cause a legend to be placed on the certificates (to the extent the Shares are certificated) representing its Existing Shares (other than the Schedule A Shares) as set forth below:

“The Securities represented by this certificate are subject to restrictions on transfer and may not be sold, transferred, pledged, encumbered, assigned, distributed, hypothecated, tendered or otherwise disposed of, including by way of merger, consolidation, share exchange or similar transaction, whether voluntarily or by operation of law, except in accordance with and subject to the terms and conditions of the Stockholders Agreement, dated as of November 21, 2005, between the registered holder hereof and Sprint Nextel Corporation.”

(c) The parties hereto agree that the legend set forth above shall be removed only upon delivery to the Company’s transfer agent of written notice signed by Sprint (which notice shall not be unreasonably withheld or delayed) after expiration of the Proxy Term that the restrictions set forth in the legend above are of no further force and effect.

4. Acknowledgment of Reliance. Each Stockholder understands and acknowledges that Sprint is pursuing the Merger (and incurring costs and expenses and foregoing other opportunities) in reliance upon such Stockholder’s execution and delivery of this Agreement.

5. No Inconsistent Agreements. Each Stockholder hereby covenants and agrees that, except as otherwise noted in Schedule A hereto, such Stockholder (a) has not entered, and such Stockholder shall not enter at any time during the Proxy Term, into any voting agreement, voting trust or option agreement with respect to the Shares beneficially owned by such Stockholder and (b) has not granted, and such Stockholder shall not grant at any time during the Proxy Term, a proxy, a consent or power of attorney with respect to the Shares beneficially owned by such Stockholder, other than the proxy granted pursuant to Section 2 hereof.

6. Representations and Warranties of each Stockholder. Each Stockholder hereby represents and warrants, severally as to such Stockholder and not jointly, to Sprint as follows:

No other actions or proceedings on the part of such Stockholder are necessary to authorize the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby. This Agreement has been duly executed and delivered by such Stockholder and, assuming this Agreement constitutes a valid and binding obligation of Sprint and the other Stockholders, constitutes a valid and binding obligation of such Stockholder, enforceable against such Stockholder in accordance with its terms.

(b) Ownership. As of the date hereof, (i) such Stockholder beneficially owns the Existing Shares listed opposite such Stockholder’s name on Schedule B hereto, and (ii) the Existing Shares (as set forth opposite such Stockholder’s name on Schedule B) constitute all of the shares of Common Stock owned by such Stockholder.

(d) Consents and Approvals. The execution and delivery of this Agreement by such Stockholder does not, and the performance by such Stockholder of its obligations under this Agreement will not, require such Stockholder to obtain any consent, approval, authorization or permit of, or to make any filing (other than Exchange Act filings) with or notification to, any Governmental Entity based on the Law of any applicable Governmental Entity, except for any of the foregoing as would not, either individually or in the aggregate, prevent or materially delay or impair the ability of such Stockholder to perform its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

(e) Absence of Litigation. As of the date hereof, there is no suit, action, investigation or proceeding pending or, to the knowledge of such Stockholder, threatened against such Stockholder before or by any Governmental Entity that would impair the ability of such Stockholder to perform its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

(f) Stockholder Has Adequate Information. Such Stockholder is a sophisticated seller with respect to its Shares and has adequate information concerning the business and financial condition of the Company to make an informed decision regarding the

sale of its Shares and has independently and without reliance upon either Buyer or Sprint and based on such information as such Stockholder has deemed appropriate, made its own analysis and decision to enter into this Agreement.

Sprint (i) is duly organized, validly existing and in good standing under the Laws of the jurisdiction of its organization and (ii) has the corporate power and authority to execute and deliver this Agreement and the Merger Agreement, and to perform its obligations hereunder and thereunder and to consummate the transactions contemplated hereby and thereby. No other actions or proceedings on the part of Sprint are necessary to authorize the execution and delivery of this Agreement or the Merger Agreement and the consummation of the transactions contemplated hereby and thereby. This Agreement and the Merger Agreement have been duly executed and delivered by Sprint and, assuming this Agreement constitutes a valid and binding obligation of the Stockholders and the Merger Agreement constitutes a valid and binding obligation of the Company, each such agreement constitutes a valid and binding obligation of Sprint, enforceable against Sprint in accordance with its terms.

(b) No Violation. Assuming the accuracy of the representations and warranties contained in Section 3.23 of the Merger Agreement and except as set forth in the Company Disclosure Letter or in the exceptions to the representation and warranty contained in Section 4.3 of the Merger Agreement, the execution and delivery of this Agreement by Sprint and the Merger Agreement by each of Sprint and Buyer does not, and the performance by Sprint of its obligations under this Agreement and by each of Sprint and Buyer of their obligations under the Merger Agreement will not, (i) conflict with or violate any law, ordinance or regulation of any Governmental Entity applicable to Sprint or Buyer or by which any of their respective assets or properties is bound or (ii) conflict with, result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or require

payment under, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which Sprint or Buyer is a party or by which Sprint or Buyer is bound, except for any of the foregoing as would not, either individually or in the aggregate, prevent or materially delay or impair the ability of (x) Sprint to perform its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis or (y) Sprint or Buyer to perform its obligations under the Merger Agreement or to consummate the transactions contemplated thereby on a timely basis.

IN WITNESS WHEREOF, the parties have signed or have caused this Agreement to be signed by their respective officers or other authorized persons thereunto duly authorized as of the date first above written.
