The Certificate of Designations designates the rights of the Company's Series A Preferred Stock (`Preferred Stock") which was issued in connection with the closing of the sale of the Preferred Stock, which was previously disclosed on November 13, 2006. The Certificate of Designation gives the Preferred Stock a liquidation preference of $1,000 per share. Dividends are non-cumulative and are payable quarterly at the rate of 8.66% per annum. If dividends on the Preferred Stock are not declared and paid for any period, no dividends may be declared on the Company's common stock for such period. The Preferred Stock is redeemable by the Company at any time, in whole or in part, at a price per share equal to the liquidation preference plus declared and unpaid dividends. If the Company completes an underwritten public offering of common stock in the future, 30,000 shares of the Preferred Stock will be mandatorily convertible into the Company's common stock and the other 10,000 shares of Preferred Stock will be convertible into the Company's common stock at the option of the holder, in each case at a price per share of common stock equal to the price per share in the public offering. In the event of a change in control of the Company, the Preferred Stock will also be convertible at the option of the holder into shares of the Company's common stock worth $40 million (plus declared and unpaid dividends), valued at the value per share of common stock in the change in control transaction. The Preferred Stock has no voting rights except as required by law, except that if the Company fails to pay six dividends, whether or not consecutive, the holders of the Preferred Stock, voting as a separate class, will be entitled to elect one director to the Company's board of directors until the Company has thereafter paid in full at least four dividends, whether or not consecutive. The Certificate of Designations is filed as Exhibit 3.1 and is incorporated by reference herein. The following exhibits are filed as part of this report.
