2. Equity Financing

     In June 2010, we entered into an equity line of credit arrangement (Equity Line) with Glengrove Small Cap Value, Ltd (Glengrove), pursuant to which Glengrove committed to purchase, upon the terms and subject to the conditions of the purchase agreement establishing the facility, up to $10 million worth of shares of our common stock, subject to a maximum aggregate limit of 5,228,893 common shares. The facility provided that we may, from time to time, over the 24-month term of the facility and at our sole discretion, present Glengrove with draw down notices to purchase our common stock at a price equal to the daily volume weighted average price of our common stock on each date during the draw down period on which shares are purchased, less a discount of 6.0%. During 2010, we completed draw downs and sales under the facility of an aggregate of 3,632,120 shares for net proceeds of approximately $4.0 million. On February 1, 2011, we completed our final draw down and sale of 1,596,773 shares for net proceeds of approximately $2.2 million. We sold to Glengrove a total of 5,228,893 shares, which is the maximum number of shares issuable under the terms of the Equity Line and the Equity Line by its terms automatically has terminated.
