SHAREHOLDERS' EQUITY

Shareholders' Equity

On January 21, 2014, the Company entered into a purchase agreement (Purchase Agreement), together with a registration rights agreement, for the sale of up to $15.0 million of shares of its common stock to Lincoln Park, subject to certain limitations, from time to time over a 30 months period, which began on April 3, 2014 and ends on October 3, 2016.

The Company may direct Lincoln Park, at its sole discretion, to purchase up to 50,000 shares of common stock in regular purchases, increasing to amounts of up to 100,000 shares depending upon the closing sale price of the common stock.  In addition, the Company may direct Lincoln Park to purchase additional amounts as accelerated purchases if on the date of a regular purchase the closing sale price of the common stock equals or exceeds $3.00 per share.  The purchase price of shares of common stock related to the future funding will be based on the prevailing market prices of such shares at the time of sales (or over a period of up to 10 business days leading up to such time), but in no event will shares be sold to Lincoln Park on a day the common stock closing price is less than the floor price of $2.50, subject to adjustment.  The Company controls the timing and amount of any sales of common stock to Lincoln Park. The Company’s sales of shares of common stock to Lincoln Park under the Purchase Agreement are limited to no more than the number of shares that would result in the beneficial ownership by Lincoln Park and its affiliates, at any single point in time, of more than 9.99% of the then outstanding shares of the common stock. The remaining capacity under this agreement is $11.3 million.  

At September 30, 2015 there was approximately $7.8 million of net capacity remaining on the At-the-Market Sales Agreement with MLV & Co. LLC (formerly McNicoll, Lewis & Vlak) which allowed us to sell shares of our common stock from time to time under a registration statement on Form S-3 filed in June 2011, pursuant to which we registered $100 million of our securities for public sale. The Form S-3 registration statement filed in June 2011 expired in July 2014.
