Neither the delivery of this Supplement and the Prospectus to which it relates nor any sale of common stock covered hereby shall, under any circumstances, create any implication that information in this Supplement is correct as of any time subsequent to the date hereof (October 5, 2004). This Supplement and the Prospectus to which it relates do not constitute an offer to, or solicitation of, any person in any jurisdiction in which such offer or solicitation may not be lawfully made.

     Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this Supplement or the Prospectus to which it relates. Any representation to the contrary is a criminal offense.

(1)	Consists solely of shares of common stock issuable upon exercise of the warrants.
(2)	Calculated based on Rule 13d-3(d)1 under the Securities Exchange Act of 1934, as amended, using 50,107,963 shares of common stock outstanding as of March 12, 2004. In calculating this amount for each selling shareholder, we treated as outstanding the number of shares of common stock issuable upon exercise of the warrants held by such shareholder, but we did not assume the exercise of warrants owned by any other shareholder.
(3)	The shares may be offered from time to time by the selling shareholders. The selling shareholders are not obligated to sell all or any portion of their shares, nor are they obligated to sell any of their shares immediately pursuant to this prospectus. Because the selling shareholders may sell all or some of their shares, no estimate can be given as to the amount of common stock that will be held by the selling shareholders upon the termination of this offering.
