WHEREAS, Zamba’s NextNet Stock can be converted to common shares of NextNet at the exchange ratio of three shares of common stock for every one share of preferred stock; and

WHEREAS, Zamba’s NextNet Stock is also subject to the Amended and Restated Investors’ Rights Agreement dated as of July 10, 2000 among Zamba, NextNet and the Investors and Founders identified therein (the “Investors’ Rights Agreement”), Right of First Refusal Agreement dated as of September 21, 1998 among the Zamba, NextNet and the Series B Purchasers identified therein (the “Right of First Refusal Agreement”), and the Voting Agreement dated September 21, 1998, by and among NextNet, the Company and certain other investors (the “Voting Agreement”); and

WHEREAS, the Purchaser is thoroughly familiar with the Company’s and NextNet’s business, financial condition and prospects; and

WHEREAS, the Purchaser desires to purchase from the Company and the Company desires to sell to the Purchaser certain of its shares of Zamba’s NextNet Stock; and

WHEREAS, the Purchaser acknowledges that there is no established trading market or other current valuation for Zamba’s NextNet Stock or the Shares to be issued hereunder;

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows:

1. Purchase and Sale of Preferred Stock. In consideration of this Agreement, the Company hereby agrees to sell to the Purchaser, and the Purchaser hereby agrees to purchase from the Company, the Shares in accordance with the following terms:

(a) The Company hereby sells to the Purchaser, and the Purchaser hereby purchases from the Company, 8,334 shares of Zamba’s NextNet Stock (the “Shares”), at a purchase price of $6.00 per share, for an aggregate purchase price of $50,004. Promptly upon execution of this Agreement, the Purchaser shall pay the full amount of the purchase price to the Company by wire transfer in immediately available funds to an account designated in writing by the Company.

(b) Promptly upon receipt of the purchase price, the Company shall present the transaction to the independent members of the Company’s Board of Directors for the approval or disapproval of the Board of Directors. If the Company’s Board of Directors disapproves the transaction, the full purchase price shall be promptly refunded to the Purchaser. If the Company’s Board of Directors approves the transaction, the Company shall, within five business days of such approval, deliver to NextNet a notice pursuant to the Right of First Offer set forth in Section 1.1 of the Right of First Refusal Agreement (the “Refusal Agreement”) dated September 21, 1998 by and among the Company, NextNet, and the holders of the Series B Preferred Stock of NextNet.

(c) If NextNet elects to exercise its right of first refusal pursuant to Section 1(b) above, the Purchase Price shall be refunded to the Purchaser within five business days of the Company’s receipt of full payment from NextNet for the Shares, and the Purchaser shall not receive any of the Shares. If NextNet declines to exercise its right of first refusal, the Company shall, within five business days after the Company’s receipt of NextNet’s notice to decline its right, notify each investor in NextNet eligible under the Refusal Agreement of its opportunity to exercise its pro rata right of first refusal pursuant to the Refusal Agreement.

(d) If any of the eligible investors in NextNet elects to exercise its pro rata right of first refusal pursuant to Section 1(c) above, the Company will forward to the Purchaser the payments the Company receives from such investor(s) within five business days of the Company’s receipt of such payment, and the number of Shares that the Purchaser will receive pursuant to this Agreement shall be reduced on a pro rata basis. Within ten business days after the expiration of the investor refusal period, the Company shall deliver to the Purchaser a certificate registered in the Purchaser’s name representing the number of Shares purchased.

2. Representations and Warranties of the Purchaser. As a material inducement for the Company’s issuance and sale of the Shares, the Purchaser represents, warrants, covenants and acknowledges to the Company that:

(a) The Purchaser understands that the issuance of the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or applicable state securities laws. Instead, the Company is issuing the Shares pursuant to exemptions from such laws and in doing so is and would be relying on, among other things, the Purchaser’s representations, warranties, covenants and acknowledgements contained herein.

(b) The Purchaser qualifies as an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act, and as further represented in Section 3 of this Agreement.

(c) The Purchaser has sufficient knowledge and experience in financial and business matters that the Purchaser is capable of evaluating the merits and risks of investing in the Shares.

(d) The Purchaser has been provided with or given access to such additional information as the Purchaser has requested from the Company (including the opportunity to meet with Company officers and to review all the documents that Purchaser may have requested) and has utilized such information to his satisfaction for the purpose of obtaining in addition to, or verifying the accuracy of the information provided, regarding the Company’s and NextNet’s business, financial condition and prospects.

(e) The Purchaser understands that the purchase of the Shares is a highly speculative investment and involves a high degree of risk. The Purchaser believes that the investment in the Shares is suitable based upon the Purchaser’s investment objectives and financial needs and the Purchaser has adequate means of providing for current financial needs and personal contingencies, has no need for liquidity of investment with respect to the Shares and can afford a complete loss of such investment.

(f) The Purchaser is acquiring the Shares for his own account, for investment purposes only, and without the intention of reselling or redistributing the Shares.

(g) The Purchaser is aware that, in the view of the Securities and Exchange Commission, a purchase of the Shares with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market values, or any change in NextNet’s condition, or in connection with a contemplated liquidation or settlement of any loan obtained for the acquisition

of the Shares and for which the Shares were pledged, would constitute an intent inconsistent with the foregoing representation.

(h) If, contrary to the Purchaser’s foregoing intentions, he should later desire to dispose of or transfer any of the Shares in any manner, the undersigned shall not do so without (i) first obtaining an opinion of counsel satisfactory to the Company and NextNet that such proposed disposition or transfer may lawfully be made without registration pursuant to the Securities Act and applicable state securities laws or (ii) registering the resale of the Shares under the Securities Act and applicable state securities laws.

(i) Neither the Company nor NextNet has any obligation to register the Shares for resale under the Securities Act or any applicable state securities laws, or to take any other action which would facilitate the availability of federal or state registration exemptions in connection with any resale of the Shares. Accordingly, the Purchaser may be prohibited by law from selling or otherwise transferring or disposing of the Shares and may have to bear the economic risk of his investment in NextNet for an indefinite period.

(j) The Purchaser, if other than an individual, represents that (a) the Purchaser was not organized for the specific purpose of acquiring the Shares; and (b) this Agreement has been duly authorized by all necessary action on the part of the Purchaser, has been duly executed by an authorized officer or representative of the Purchaser, and is a legal, valid, and binding obligation of the Purchaser enforceable in accordance with its terms.

(k) There is no investment banker, broker, finder or other intermediary which has been retained by or is authorized to act on behalf of Purchaser who might be entitled

to any fee or commission from the Company upon consummation of the transactions contemplated by this Agreement.

(l) Purchaser agrees to be bound by the transfer restrictions described in Section 3.6 of the Series A Preferred Stock Purchase Agreement dated as of September 21, 1998 between Zamba and NextNet.

(m) Purchaser acknowledges that the provisions of the Right of First Refusal Agreement dated as of September 21, 1998 among the Zamba, NextNet and the Series B Purchasers identified therein shall continue to apply to the Shares held by Purchaser.

(n) Purchaser acknowledges that he or she has already received a copy of the Amended and Restated Investors’ Rights Agreement dated as of July 10, 2000 among Zamba, NextNet and the Investors and Founders identified therein (the “Investors’ Rights Agreement”). Purchaser understands that, pursuant to the terms of the Investors’ Rights Agreement, the registration rights described in Section 1 and the right of first offer described in Section 2.6 thereof have not been assigned to the Purchaser by Zamba. Accordingly, the Purchaser is not entitled to any registration rights or rights of first offer with respect to the Purchaser’s ownership of the Shares.
