Item 8.1 Other Events.

On April 30, 2012, we completed our offering of up units (the “Units”) at $1.70 per Unit. Each unit consisted of one share of common stock and one-half warrant. Each whole warrant entitles the holder to purchase an additional share of common stock at $1.70 per share at any time prior to March 31, 2014. We sold a total of 1,536,248 Units for gross proceeds of $2,611,622. These Units were issued without registration under the Securities Act by reason of the exemption from registration afforded by the provisions of Section 4(a)(5) and/or Section 4(a)(2) thereof, and Rule 506 promulgated thereunder, as a transaction by an issuer not involving any public offering. Each of the 48 investors in this offering was an accredited investor as defined in Regulation D. Each investor delivered appropriate investment representations with respect to these sales and consented to the imposition of restrictive legends upon the stock certificates representing the shares and warrants. Each investor was afforded the opportunity to ask questions of our management and to receive answers concerning the terms and conditions of the transaction. We paid selling commissions in the amount of $196,010 to licensed broker/dealers who acted as placement agents in this offering and issued 142,409 warrants as additional compensation to these placement agents. The terms and conditions of the selling agent warrants are essentially identical to the terms and conditions of the warrants sold to investors as part of the Units. The securities sold in this offering were not and will not be registered under the Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
