The exercise price for the common stock underlying the warrant is $1.02 per share. The closing sale price of our common stock on October 4, 2002 was $0.20. The warrant is immediately exercisable and may be exercised either by payment of the exercise price or by net exercise. On July 11, 2002, Cagan McAfee Capital Partners, LLC transferred 100,000 shares underlying the warrant to Alta Partners Discount Convertible Arbitrage Holdings, Ltd. Under the terms of the warrant, we agreed to register all of the shares of common stock underlying the warrant. This prospectus relates to the resale of up to 600,000 shares of our common stock issuable upon the exercise of the warrant. The prices at which the selling stockholders may sell the shares will be determined by the prevailing market for the shares or in negotiated transaction. See “Selling Stockholders.”
