Executive Officers and Directors: -------------------------------- In accordance with the provisions of General Instruction C to Schedule 13D, information concerning the executive officers and directors of the Filing Parties is included in Schedule A hereto and is incorporated by reference herein. (d) Criminal Proceedings -------------------- During the last five years, neither the Filing Parties (or a controlling entity thereof) nor any executive officer or director of any of the Filing Parties (or a controlling entity thereof) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). (e) Civil Securities Law Proceedings -------------------------------- During the last five years, neither the Filing Parties (or a controlling entity thereof) nor any executive officer or director of any of the Filing Parties (or a controlling entity thereof) has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Page 8 of 12 Item 3. Source and Amount of Funds or Other Consideration. The Filing Parties used their working capital funds to purchase the shares of Common Stock of the Company (the "Shares") to which this statement relates. The amount of funds used to date to acquire the Shares is approximately $6,035,018 (exclusive of brokerage fees and commissions). Item 4. Purpose of Transaction. The Filing Parties acquired their holdings of the Common Stock because they believed that the Common Stock represented a favorable investment opportunity. The Filing Parties believe that the current market valuation of the Common Stock does not fully reflect the inherent value of the Company's business. Furthermore, the Filing Parties have come to believe that the Board of Directors (the "Board") should consider thoroughly, potential opportunities to enhance shareholder value through, among other options, a business combination or sale of the company or its assets. The Filing Parties have no present intention, plans or proposals to change the existing senior management or the Board of the Company, or to effect, among other things, a business combination or sale of the Company or its assets. The Filing Parties will, from time to time, revisit the purpose of their investment in the Company. If, in the estimation of the Filing Parties, the divergence between the market valuation of the Common Stock and the inherent value of the Company's business persists, the Filing Parties may take such action as they believe is necessary to effectuate an extraordinary corporate transaction, such as a merger, asset sale or reorganization of the Company. Accordingly, future acquisitions of the Company's Common Stock may be for the purpose of, among other things, effecting an extraordinary corporate transaction, such as a merger, asset sale or reorganization of the Company. Item 5. Interest in Securities of the Issuer. (a)-(b) The aggregate number and percentage of the outstanding Common Stock of the Company beneficially owned (i) by each of the Filing Parties, and (ii) to the knowledge of the Filing Parties, by each other person who may be deemed to be a member of the Group, is as follows:
