Item 3.02 Unregistered Sales of Equity Securities. On June 1, 2010 the Company sold 1,000,000 shares of common stock to a private investor at a price of $0.20 per share. The shares of common stock are restricted securities, as that term is defined in Rule 144 of the Securities and Exchange Commission. The Company relied upon the exemption provided by Section 4(2) of the Securities Act of 1933 in connection with the sale of these securities. The investor which acquired the shares was sophisticated and was provided with full information regarding the Company. There was no general solicitation in connection with the offer or sale of the securities. The investor which acquired these securities acquired them for its own account. The certificate representing these securities bears a restricted legend providing that they cannot be sold except pursuant to an effective registration statement or an exemption from registration. No commission or other form of remuneration was given to any person in connection with the sale of these securities. Item 9.01 Financial Statements and Exhibits None
