*		Indicates beneficial ownership of less than 1.0% of the Company’s outstanding common stock.
(1)		Under SEC rules, the number of shares of common stock into which shares of the Company’s series A convertible preferred stock are convertible within 60 days of August 17, 2004. Also includes options of Mr. Grant, one of the Company’s directors, to purchase 2,000 shares of Common Stock.
(2)		The Company filed a supplement to the Prospectus on March 31, 2004 that registered up to 736,492 shares of Common Stock, which could be obtained through the conversion of Salix Ventures II, L.P.’s shares of the Company’s series A convertible preferred stock plus any accrued dividends, for resale by the limited partners of Salix Ventures II, L.P. (“Salix Ventures”) and by the general partners of Salix Partners II, the general partner of Salix Ventures . On or before April 1, 2004, Salix Ventures distributed 364,871 shares to its limited partners and the general partners of its general partner. These shares were obtained through the conversion of 50% of its shares of the Company’s series A preferred stock plus any accrued dividends. Salix Ventures now has determined to sell for its own account the shares of Common Stock that may be obtained upon conversion of its shares of the Company’s series A preferred stock plus any accrued dividends, rather than distribute the shares to its limited partners and to the general partners of Salix Partners II.

Investing in our common stock involves a high degree of risk.
