The Series C-2 Preferred is convertible into shares of the Company’s Common Stock, par value $.01 per share (the “Common Stock”), as provided in the Charter.

1B. Purchase and Sale of the Series C-2 Preferred. At the Initial Closing (defined below), the Company shall sell to each Purchaser and, subject to the terms and conditions set forth herein, each Purchaser shall purchase from the Company the number of shares of Series C-2 Preferred set forth opposite such Purchaser’s name on the Schedule of Purchasers attached hereto at a per share price for such Series C-2 Preferred equal to $0.35, payable in accordance with Section 1C hereof. The sale of the Series C-2 Preferred to each Purchaser shall constitute separate sales hereunder.

1C. The Closings. The initial closing of the separate purchases and sales of the shares of Series C-2 Preferred (the “Initial Closing”) shall take place at the offices of Xxxx, Xxxxxx & Xxxxxxxxx LLP, Xxx Xxxxx XxXxxxx Xxxxxx, Xxxxxxx, Xxxxxxxx 00000 at 10:00 a.m. on the date hereof, or at such other place or on such other date as may be mutually agreeable to the Company and each Purchaser.

(i) At the Initial Closing and, if any, the subsequent closing on September 30, 2004 pursuant to Section 1D hereof (the “Subsequent Closing”), the Company shall deliver to each Purchaser acquiring shares of Series C-2 Preferred at such closing stock certificates evidencing the Series C-2 Preferred to be purchased by such Purchaser at such closing, registered in such Purchaser’s or its nominee’s name, upon payment of the purchase price thereof by wire transfer of immediately available funds to a bank account of the Company designated to the Purchasers prior to such closing, in the aggregate amount with respect to such closing set forth opposite such Purchaser’s name on the Schedule of Purchasers.

At the Subsequent Closing, if any, the Company shall exchange all shares of Preferred Stock of the Company held by each Purchaser at such Closing, or any other stockholder of the Company that has delegated its ability to participate in the transactions contemplated by this Agreement to such Purchaser, for the number of shares of Series C-2 Preferred equal to the Exchange Price, provided that such Purchaser or stockholder has participated on a pro rata (or greater) basis in accordance with the terms of the Company’s offering of Series C-2 Preferred in connection herewith.

(ii) maintain and keep its properties in reasonably good repair, working order and condition;

(iii) file, file application for, seek and pursue all appropriate licenses, authorizations and permits and all appropriate patents, trademarks and other intellectual property protection; with respect to any new discoveries, inventions, products and product developments;

(iv) pay and discharge when payable all Taxes, assessments and governmental charges imposed upon its properties or upon the income or profits therefrom (in each case before the same becomes delinquent and before penalties accrue thereon) and all claims for labor, materials or supplies which if unpaid would by law become a lien upon any of its property, unless and to the extent that the same are being contested, in good faith and by appropriate proceedings and adequate reserves (as determined in accordance with generally accepted accounting principles, consistently applied) have been established on its books with respect thereto;

(v) comply with all other obligations which it incurs pursuant to any contract or agreement, whether oral or written, express or implied, as such obligations become due;

(vi) comply with all applicable laws, rules and regulations of all governmental authorities; and

Neither the Company nor any Subsidiary shall take any action, or fail to take any action, which could result in the invalidity, abandonment, misuse, or unenforceability of such Intellectual Property Rights or which could infringe upon or misappropriate any rights of other Persons.

3F. Qualified Small Business. The Company covenants that so long as any of the shares of Series C-2 Preferred or the Common Stock into which such shares are converted are held by a Purchaser (or a transferee in whose hands shares of Common Stock or Series C-2 Preferred are eligible to qualify as “Qualified Small Business Stock” as defined in Section 1202(c) of the IRC), it will use its reasonable efforts (including complying with any applicable filing or. reporting requirements imposed by the IRC on issuers of Qualified Small Business Stock) to cause such securities, or the Common Stock into which they are converted, to qualify as Qualified Small Business Stock; provided, however, that “reasonable efforts” as used in this Section 3F shall not be construed in such a way as to impose undue hardship on the Company or to require the Company to operate its business in a manner which would adversely affect its business, limit its future prospects or alter the timing or resource allocation related to its planned operations or financing activities.

3G. Authorized and Reserved Common Stock and Series C-2 Preferred. The Company agrees to take and to cause to be taken all action necessary to assure that a sufficient quantity of Series C-2 Preferred is timely authorized and reserved for issuance as dividends on Series C-2 Preferred, and to assure that a sufficient quantity of Common Stock is timely authorized and reserved for issuance to accommodate conversion of Series C-2 Preferred (including Series C-2 Preferred issued in the future and issued as dividends on Series C-2 Preferred).

The Company shall take all action as may be necessary to assure that all such shares of Series C-2 Preferred and Common Stock may be so issued without violation of any laws or governmental regulations.

3H. Designation of Directors. The Company shall use its best efforts to cause any directors designated by the Purchasers as provided in the Stockholders’ Agreement to be elected to the board of directors of the Company, in accordance with the terms of the Stockholders’ Agreement.
