(a) If HT desires to sell Shares of the Company beneficially owned by it (a "TRANSFER"), other than (i) to an Affiliate; (ii) in connection with an Approved Spin Off; (iii) a Transfer by HT, or an Affiliate of HT, directly or indirectly, of no more than 750,000 Shares in any one transaction or in any series of related transactions or 5,000,000 Shares in the aggregate over all transactions covered by this clause (iii); provided, however, that after a Public Offering that generates gross proceeds to the Company of at least $65,000,000 or after the consummation of a Combination Transaction with a Listed Company, such figures shall be increased so that HT, or an Affiliate of HT, may Transfer, directly or indirectly, no more than 1,500,000 Shares in any one transaction or in any series of related transactions or 10,000,000 Shares in the aggregate over all transactions covered by this clause; or (iv) in connection with a Public Offering, HT shall deliver to the Company and the Investors written notice (the "CO-SALE NOTICE") that the Investors shall have the right, exercisable upon written notice to HT within fifteen (15) days after receipt of the Co-Sale Notice, to participate in such Transfer on the same terms and conditions as are applicable to HT. Such notice shall indicate the number of Shares that HT wishes to sell, as well as a detailed description of the terms and conditions of the sale, including the price per share and the identity of the offeror. To the extent the Investors exercise this right of participation in accordance with the terms and conditions set forth below, the number of Shares that HT may sell in the transaction shall be correspondingly reduced. The failure of an Investor to give a notice of its desire to participate within the required time period will be deemed an election by it not to participate. (b) If Investors elect to participate in the Transfer, HT shall grant to such electing Investors (the "ELECTING INVESTORS") the right to sell to the offeror such number of Shares equal to the total number of Shares to be purchased by the offeror multiplied by a fraction, the numerator of which is the total number of Shares held by the Investors and the denominator of which is the total number of Shares held by the Electing Investors plus the total number of Shares held by HT. The number of Shares to be sold between the Electing Investors shall be based on their respective pro rata total ownership interests in the Company, calculated on an "as converted" basis, and such sale shall be made at the time, price and upon the terms specified in the Co-Sale Notice. (c) If an Investor elects to participate in the Transfer pursuant to this Section 2, it shall promptly (but in no event later than five business days after it timely delivers its election notice) deliver to HT for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent the number of Shares which the Investors are entitled to sell; 3 and (ii) a written notice to convert such Preferred Stock into Common Stock and deliver Common Stock as contemplated hereby. The Company agrees to make any such conversion concurrent with the actual transfer of such Shares to the purchaser. (d) The Common Stock certificate or certificates that HT receives pursuant to Section 2.1(c) shall be transferred to the prospective purchaser in consummation of the sale of the Shares pursuant to the terms and conditions specified in the Co-Sale Notice, and HT shall concurrently therewith remit to the Electing Investors that portion of the sale proceeds to which the Investors is entitled by reason of their participation in such sale. To the extent that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase shares or other securities from an Investor exercising its rights of co-sale hereunder, HT shall not sell to such prospective purchaser or purchasers any Shares unless and until, simultaneously with such sale, HT shall purchase such shares or other securities from the Investors on the same terms and conditions specified in the Co-Sale Notice. (e) The exercise or non-exercise of the rights of the Investors hereunder to participate in one or more Transfers made by HT shall not adversely affect their rights to participate in subsequent Transfers subject to this Section 2. (f) If Investors do not elect to participate in the Transfer subject to the Co-Sale Notice, HT may, not later than sixty (60) days following delivery to the Company of the Co-Sale Notice, enter into an agreement (if it has not already entered into such an agreement) providing for the closing of the Transfer within thirty (30) days of such agreement on terms and conditions not more favorable to HT than those described in the Co-Sale Notice. Any proposed Transfer on terms and conditions more favorable to HT than those described in the Co-Sale Notice, as well as any subsequent proposed Transfer of any of the Shares by HT, shall again be subject to the co-sale rights of the Investors and shall require compliance by HT with the procedures described in this Section 2. (g) In the event the proposed purchaser notifies HT of its desire to purchase a number of Shares that is different from the amount covered in the Co-Sale Notice, HT shall promptly notify the Company and the Investors of the new terms offered by the proposed purchaser. Accordingly, the number of Shares that the proposed purchaser desires to purchase shall be substituted for the number previously included in the Co-Sale Notice and the Investors shall have an additional seven (7) business days from receipt of such notice to determine whether they will participate in such Transfer pursuant to the terms of Co-Sale Notice. (h) It shall be a condition to any Transfer by which would cause HT (in combination with the Investors) to own less than 51% (by vote) of the outstanding common stock of the Company that such proposed purchaser agree in writing to vote their shares in the manner set forth in Section 4 hereof for the period of time required pursuant to Section 4 hereof, if Section 4 hereof would continue to be applicable after such sale, taking into account the shares sold by the Investors pursuant to their co-sale rights in such transaction. 4 SECTION 3 BRING ALONG RIGHT. Prior to a Public Offering of the Company that generates gross proceeds to the Company of at least $30 million or consummation of a Combination Transaction with a Listed Company, if HT wishes to sell all of its Shares to a third party which is not an Affiliate (an "ACQUIRER"), and assuming such sale were being made by the Company such sale would not constitute either a Change of Control or a Combination Transaction (each as defined in the Certificate of Designation) which would require the approval of a majority of the holders of the Series A Preferred Stock, HT shall have the following rights: (a) If HT proposes to sell, transfer, pledge or otherwise dispose ("DISPOSE" or "DISPOSITION") of all (but not less than all) of the Shares owned by it to a Person (other than any of its Affiliates) who or which has delivered a good faith written offer to purchase all of HT's shares (a "BONA FIDE PURCHASER"), then, notwithstanding anything in this Agreement to the contrary, HT may require the Investors to Dispose of their Shares (the "BRING-ALONG RIGHT") to such Bona Fide Purchaser for the same consideration (in amount and type) per share as HT is to receive from the Bona Fide Purchaser, and otherwise on the same terms and conditions upon which HT proposes to effect the Disposition of its Shares. (b) In the event that HT desires to exercise its Bring-Along Right pursuant to Section 3(a), HT shall deliver to the Company and the Investors written notice ("SALE NOTICE"), at least twenty (20) days prior to the closing of such Disposition, setting forth the consideration per share to be paid by such Bona Fide Purchaser and the other terms and conditions of such Disposition. Within ten (10) days following the date of a subsequent written notice (the "CLOSING NOTICE"), stating that the closing will occur within ten (10) days of the Closing Notice, each of the Investors shall deliver in trust to HT (i) a stock certificate or certificates evidencing such Investors Shares, together with an appropriate assignment separate from certificate duly executed in a proper form to effect the Disposition of such Shares from the Investors to the Bona Fide Purchaser on the books and records of the Company, and (ii) a limited power-of-attorney authorizing HT to effect the Disposition of such Shares pursuant to the terms of such Bona Fide Purchaser's offer as such terms may be modified by HT, provided, that all of the Investors' Shares are disposed of for the same consideration per share (subject to appropriate adjustment to reflect any differences in the rights and preferences of Shares of different classes or series) and otherwise on the same terms and conditions upon which HT effects the Disposition of its Shares. In the event that any Investor shall fail to deliver such stock certificate(s), and assignment separate from certificate to HT, the Company shall cause a notation to be made on its books and records to reflect that the Shares of such Investor are bound by the provisions of this Section 3 and that the Disposition of such Shares may be effected without such Investor's consent or surrender of its Shares. 5 (c) In addition, in the event HT exercises its Bring-Along Right under Section 3(a), the Investors shall be required to make to a Bona Fide Purchaser such unqualified representations and warranties with respect to their Shares as are set forth in Section 3(f) hereof. (d) Promptly (but in no event later than the day of receipt) after the consummation of the Disposition of Shares pursuant to this Section 3, HT shall (i) deliver notice thereof to the Investors, (ii) remit to the Investors the total sales price of their respective Shares Disposed of pursuant thereto, and (iii) furnish such other evidence of the completion and time of completion of such Disposition and the terms thereof as may be reasonably requested in writing by the Investors. (e) If, within sixty (60) days after the Investors' delivery of the Closing Notice required pursuant to Section 3(b), HT has not completed the Disposition of its Shares and that of the Investors in accordance herewith, HT shall return to the Investors (i) the stock certificates and assignments of certificates with respect to the Investors' Shares which the Investor delivered pursuant to this Section 3 and (ii) the related limited power-of-attorney delivered pursuant to this Section 3. Upon the Investors' receipt of such materials, all the restrictions on Disposition contained in this Agreement with respect to the Shares owned by the Investors shall again be in effect. (f) All Dispositions of Shares to be made pursuant to this Section 3 shall be subject to the following terms: (i) the Investors shall deliver to the Bona Fide Purchaser the certificates evidencing the Shares, together with duly executed stock transfer powers in favor of the Bona Fide Purchaser or its nominees and such other documents, including evidence of ownership and authority, as the Bona Fide Purchaser may reasonably request; (ii) the Investors agree that all Shares of the Investor Disposed to the Bona Fide Purchaser in accordance with this Section 3 shall be sold free and clear of any lien, claim, charge, pledge, mortgage, encumbrance or third party interest ("ENCUMBRANCE"); (iii) except as otherwise specifically set forth herein, the Investor shall not be required to make any representations or warranties to any Person in connection with such Disposition, except as to (A) good title to the Shares being Disposed, (B) the absence of Encumbrances with respect to the Shares being Disposed, (C) its valid existence and good standing (if applicable), and (D) the authority for, and validity and binding effect of (as against such Investor) any agreement entered into by such Investor in connection with such Disposition,; and (iv) the Investors shall not be required to provide any indemnities in connection with such Disposition except for breach of the representations and warranties specifically required by the terms of this Agreement. 6 SECTION 4 VOTING AGREEMENT; BOARD OF DIRECTORS. 4.1 COMPOSITION OF BOARD OF DIRECTORS. The Board of Directors of the Company shall be constituted pursuant to the terms of this Section 4.

HT agrees to vote in favor of (i) two (2) directors nominated by the Investors, so long as the Investors beneficially own at least 12.5% of the Company's common stock, calculated on an "as converted" basis and calculated taking into account (A) shares issuable under currently outstanding options, (B) shares issuable upon the exercise of warrants issued to Sprint Spectrum L.P. pursuant to contractual obligations entered into prior to the date hereof, (C) shares issuable to First Union Investors, Inc. pursuant to the First Union Conversion (as such term is defined in the Securities Purchase Agreement) and (D) shares issuable upon exercise of warrants to be issued in connection with the Senior Notes Offering or (ii) one (1) director nominated by the Investors, so long as the Investors beneficially own between 5% and 12.49% of the Company's common stock, calculated on an "as converted" basis and calculated taking into account (A) shares issuable under currently outstanding options, (B) shares issuable upon the exercise of warrants issued to Sprint Spectrum L.P. pursuant to contractual obligations entered into prior to the date hereof, (C) shares issuable to First Union Investors, Inc. pursuant to the First Union Conversion and (D) shares issuable upon exercise of warrants to be issued in connection with the Senior Notes Offering. Notwithstanding the foregoing, HT agrees to vote in favor of two (2) directors nominated by the Investors until the earlier of (A) the completion of the Company's Public Offering that generates gross proceeds of at least $65 million and (B) May 1, 2001. To the extent the Investors beneficially own less than 5% of the Company's common stock, calculated on an "as converted" basis and calculated taking into account (A) shares issuable under currently outstanding options, (B) shares issuable upon the exercise of warrants issued to Sprint Spectrum L.P. pursuant to contractual obligations entered into prior to the date hereof, (C) shares issuable to First Union Investors, Inc. pursuant to the First Union Conversion and (D) shares issuable upon exercise of warrants to be issued in connection with the Senior Notes Offering, the Investors shall cause the Investor Directors to resign their seats on the Board of Directors.

(c) One Investor Director shall be elected as a Class I director, and one Investor Director shall be elected as a Class III director. (d) In the event that any director (a "WITHDRAWING DIRECTOR") nominated in the manner set forth in Section 4.1 hereof is unable to serve, or once having commenced to serve is removed or withdraws from the Board of 7 Directors, such Withdrawing Director's replacement (the "SUBSTITUTE DIRECTOR") will be nominated in the same manner in which such Withdrawing Director was nominated in accordance with Section 4.1(a) hereof. Each of the Shareholders shall take all action necessary to cause the prompt election of such Substitute Director. 4.2 DIRECTORS' EXPENSES. The Company shall reimburse members of the Company's Board of Directors for reasonable expenses, such as travel and hotel, incurred in connection with the performance of their duties as a Director. 4.3 DIRECTORS' LIABILITY AND INDEMNIFICATION.

SECTION 5 ADDITIONAL LOCK-UP. In connection with the Company's Initial Public Offering, HT shall agree not to sell or otherwise transfer, directly or indirectly, its Shares until one hundred eighty (180) days after the expiration of the relevant lock-up period required by the terms of any such Initial Public Offering (it being understood that such lock-up period shall be no shorter than such any lock-up period that is applicable to the Investors); provided, however, that at any time after the expiration of the relevant lock-up period, HT and holders who receive Common Stock in an Approved Spin-Off, if any, may sell, transfer and/or distribute in the aggregate up to such number of Shares as would generate Ten Million Dollars ($10,000,000) of proceeds.
