Stockholders' Equity

On April 23, 2012, the Company entered into a $6,600,000 purchase agreement with Lincoln Park Capital Fund pursuant to which the Company has the right to sell to Lincoln Park up to $6,600,000 in shares of the Company’s common stock, and on April 24, 2012, the Company entered into another purchase agreement with Lincoln Park Capital Fund pursuant to which the Company has the right to sell to Lincoln Park up to $3,400,000 in shares of the Company’s common stock, subject to certain limitations. We received proceeds of $132,000, net of financing costs of $152,000, under the $3,400,000 Purchase Agreement and issued a total of 1,754,974 shares of common stock in the second quarter of 2012. As consideration for its commitment to purchase common stock under the $3,400,000 Purchase Agreement, the Company issued to Lincoln Park 281,030 shares of common stock.  Access to funding under the facility is dependent upon our shares being listed on a national exchange, and as our shares were delisted from the NYSE Amex exchange on October 31, 2012, the Company can no longer raise funds from the facility.
