(f) Capital Focus III is a limited partnership organized in the State of Delaware. Partners III is a limited liability company organized in the State of Delaware. Each of Tullis, Neuscheler, Dickerson, Hohnke and Buono are United States citizens. Item 3. Source and Amount of Funds or Other Consideration. Funds for the purchase of the Series B-1 Preferred Stock and the Warrants (each as defined below) related to the shares of Common Stock reported herein were derived from the available capital of Capital Focus III. A total of approximately $10,000,000 was paid to acquire the Series B-1 Preferred Stock and the Warrants. ITEM 4 PURPOSE OF TRANSACTION. The Reporting Persons acquired the shares of Common Stock for investment in the ordinary course of business because they believed that the shares of Common Stock, when purchased, represented an attractive investment opportunity based on the Issuer's prospects and strategy. On May 15, 2006, Capital Focus III entered into a Securities Purchase Agreement (the "SECURITIES PURCHASE AGREEMENT"), attached hereto as Exhibit 2 and incorporated herein by reference pursuant to which the Issuer authorized a new series of convertible preferred stock designated as Series B-1 Convertible Preferred Stock, par value $0.01 (the "SERIES B-1 PREFERRED STOCK") pursuant to a Certificate of Designations, Preferences and Rights of Series B-1 Preferred Stock (the "SERIES B-1 CERTIFICATE OF DESIGNATIONS"), in the form attached hereto as Exhibit 3 and incorporated herein by reference, and warrants (the "WARRANTS", together with the Series B-1 Preferred Stock, the "SECURITIES"), in the form attached hereto as Exhibit 4 and incorporated herein by reference. The Series B-1 Preferred Stock has a stated value of $1,000 per share (the "PREFERRED STATED VALUE") and is initially convertible into shares of Common Stock at an initial conversion price of $ 1.5338 (subject to adjustment as provided in the Series B-1 Certificate of Designations, the "PREFERRED CONVERSION PRICE"). The Warrants are exercisable for a period of five years at an initial exercise price of $1.639 per share (subject to adjustment as provided in the Warrants). Accordingly, on May 26, 2006 at the closing of the Securities Purchase Agreement, 10,000 shares of Series B-1 Preferred Stock that are initially convertible into 6,519,755 shares of Common Stock and Warrants initially exercisable into 2,281,914 shares of Common Stock were issued to Capital Focus III for a gross purchase price of $10 million (the "TRANSACTION"). On May 15, 2006, the Issuer and Capital Focus III entered into a Registration Rights Agreement (the "REGISTRATION RIGHTS AGREEMENT"), which is attached hereto as Exhibit 5 and incorporated herein by reference, pursuant to which the Issuer agreed to provide certain registration rights with respect to the securities issued under the Securities Purchase Agreement, including the obligation of the Issuer to file with the Securities and Exchange Commission (the "SEC"), as soon as practicable after the closing date of the Transaction, but in no event later than 60 calendar days after a request is made by the Required Holders (as defined in the Registration Rights Agreement) which request may be made any time after the earlier of (x) December 31, 2006 and (y) such time after the date of the Registration Rights Agreement that the Company is eligible to file a Registration Statement thereunder on Form S-3, a Registration Statement on Form S-3 covering the resale of all Registrable Securities (as defined in the Registration Rights Agreement) of Capital Focus III. Under the Series B-1 Certificate of Designations, so long as Capital Focus III or any of its affiliates continues to hold at least twenty five percent of the cumulative aggregate number of Series B-1 Preferred Stock issued to the Capital Focus III on the Initial Issuance Date (as defined in the Series B-1 Certificate of Designations), Capital Focus III is entitled to elect one director to the Board of Directors of the Issuer (an "INVESTOR DESIGNEE") at each annual election of directors; provided, however, that any Investor Designee other than Richard J. Miller ("MILLER") must be approved by the Company, such approval not to be unreasonably withheld or delayed. Miller initially is serving as the Investor Designee. The Reporting Persons intend to continue to review and evaluate their investment in the Issuer. Depending on the price and availability of funds, subsequent developments affecting the Issuer, the Issuer's business, other investment and business opportunities available to the Reporting Persons and general stock market, economic and other factors that the Reporting Persons may deem relevant from time to time, the Reporting Persons may maintain their investment at current levels or sell all or a part of their investment, or acquire additional shares of Common Stock or other securities of the Issuer at any time. Any acquisition or disposition of shares of Common Stock by the Reporting Persons may be effected through open market or privately negotiated transactions, or otherwise. Except to the extent set forth above, or in any other Item hereof, the Reporting Persons do not have any present plans or proposals that relate to or would result in any of the actions required to be described in Item 4 of this Schedule 13D. However, the Reporting Persons may, at any time and from time to time, review or reconsider their position with respect to the Issuer, and formulate (and modify) plans or proposals with respect to any such matters. At the request of the Issuer, the Reporting Persons may provide additional assistance to the Issuer in the development of its business and business plan. ITEM 5.
