ITEM 3.02 UNREGISTERED SALES OF EQUITY SECURITIES On January 18, 2005, we gave notice to all holders of Series D and Series E Preferred Stock that we had elected to convert the shares of Series D and Series E Preferred Stock to common stock. The designations, rights and preferences of the Series D and Series E Preferred Stock permitted us to exercise this conversion option if the market price of our common stock exceeded $9.50 for ten consecutive trading days and certain other conditions were satisfied. The price condition was satisfied on January 6, 2005. The notice of conversion was effective immediately for the Series D Preferred Stock, and resulted in all 50,000 issued and outstanding shares of Series D Preferred Stock converting into an aggregate of 129,259 shares of common stock. The notice of conversion for the Series E Preferred Stock will be effective on February 1, 2005, and it is anticipated that on that date, all 233,250 issued and outstanding shares of Series E Preferred Stock will convert into an aggregate of 801,306 shares of common stock. The shares of common stock that will be issued upon conversion of the Series D and Series E Preferred Stock will be issued in reliance upon the exemption from registration under the Securities Act of 1933 provided by Section 3(a)(9) of such act. These shares of common stock are registered for resale under the Securities Act pursuant to currently-effective registrations statements. On December 23, 2004, we sold 42,500 shares of common stock upon exercise of an outstanding warrant held by one accredited investor. The exercise price was $2.00 per share, for gross proceeds to us of $85,000. The shares were sold in reliance upon the exemption from registration under the Securities Act provided by Section 4(2) and Regulation D, Rule 506 under such act.
