Item 3.02   Unregistered Sales of Equity Securities.

      On April 25, 2007 the Company sold 1,998,500 shares of its common stock to
a group of private investors. As part of this same financing the Company sold an
additional 140,500 shares to private investors on May 4, 2007. The shares were
sold at a price of $2.25 per share and are restricted securities as that term is
defined in Rule 144 of the Securities and Exchange Commission.

      In connection with the sale of these 2,139,000 shares the Company paid a
commission of $240,638 to Salman Partners Inc. the sales agent for the offering.
Salman Partners also received warrants which allows Salman Partners to purchase
106,950 shares of the Company's common stock at a price of $2.81 per share. The
warrants expire in 2009.

      The Company has agreed to file a registration statement with the
Securities and Exchange Commission registering the resale of the shares sold to
the investors, as well as the shares issuable upon the exercise of the warrant
issued to Salman Partners, and have it declared effective by September 21, 2007.
If the registration statement is not filed and declared effective by this date,
the Company will issue to the investors, as a group, 85,560 common shares plus
16,043 additional common shares for each month the registration statement
remains unfilled or not effective.

      The Company relied upon the exemption provided by Section 4(2) of the
Securities Act of 1933 for the sale of these securities.
