SECTION 3 - SECURITIES AND TRADING MARKETS Item 3.02 Unregistered Sales of Equity Securities On July 18, 2007 Sionix completed an offering of $1,025,000 of Subordinated Convertible Debentures to a group of institutional and accredited investors. The Subordinated Convertible Debentures are convertible into shares of Common Stock of Sionix at an initial conversion rate of $ .22 per share, subject to antidilution adjustments. For each $100,000 of Convertible Debentures purchased, the investor received Warrants to purchase 227,272 shares of Common Stock. Each Warrant entitles the holder to purchase one share of common stock of Sionix (the "Warrant Shares") for a period of five years at a price of $0.50 per Warrant Share. Under the terms of the Registration Rights Agreement, Sionix is required to file a registration statement under the Securities Act of 1933 in order to register the resale of the shares of Common Stock issuable upon conversion of the Subordinated Convertible Debentures and exercise of the Warrants (collectively, the "Registrable Securities"). If Sionix does not file a registration statement with respect to the Registrable Securities within forty-five days following the closing of the Offering, or if the Registration Statement is not declared effective by the Securities and Exchange Commission within 90 days, then Sionix must pay to each purchaser damages equal to 1.5% of the purchase price paid by the purchaser for its Subordinated Convertible Debentures, for each 30 days that transpires after these deadlines. The amount of the aggregate damages payable by Sionix is limited to 15% of the purchase price. Southridge Investment Group LLC, Ridgefield, Connecticut ("Southridge") acted as agent for Sionix in arranging the transaction, and received a placement fee of $102,500. Southridge also received warrants to purchase 698,863 shares of Common Stock of Sionix, on the same terms and conditions as the Warrants issued to the purchasers. Sionix believes that the offering and sale of the Subordinated Convertible Debentures, Warrants and underlying Common Stock were exempt from the registration requirements of the Securities Act of 1933, as amended, by reason of Regulation D thereunder or Section 4(2) thereof. Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
