The Company intends to use the net proceeds for working capital and general corporate purposes.

The offers and sales described above are part of the Company’s offering of a total of up to 15,000 shares of Series D (which are convertible into 34,160,784 shares of common stock, subject to adjustment) and Warrants to purchase up to 17,080,392 shares of common stock (representing 50% warrant coverage on an as-converted basis) for total gross proceeds of up to $15,000,000.
