On July 19, 2007, we entered into a warrant redemption agreement with a warrant holder, whereby at our option, we agree to redeem certain warrants representing the right to acquire an aggregate of up to 7,000,000 shares of our common stock, through October 2007. The warrants may be redeemed in quantities not to exceed 2,000,000 warrants in the first two calendar months and 3,000,000 in the last calendar month, at a price equal to the product of (a) the volume weighted average of the daily volume weighted average prices of our common stock for all trading days in the applicable calendar month, minus the exercise price of the warrant, multiplied by (b) the number of shares being redeemed from that warrant. The warrant holder is prohibited from exercising any of the warrants as long as we are in compliance with the agreement. Additionally, the warrant holder is prohibited from purchasing any shares of our common stock on the open market during any “pricing month” defined in the agreement as the calendar month immediately preceding the calendar month in which we deliver the redemption notice to the warrant holder. On August 1, 2007, we agreed to redeem 2,000,000 warrants for $921,855 and payment for the redemption occurred in August 2007 .
