(the "Issuer") beneficially owned by Millennium Partners, L.P. as of December 6, 2001 and amends and supplements the Schedule 13G dated September 11, 2000, as previously amended (the "Schedule 13G"), previously filed by the reporting person in connection with its beneficial ownership of shares of Common Stock. Except as set forth herein, the Schedule 13G is unmodified. Item 4. Ownership. Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1.

In accordance with Rule 13d-4 under the Securities Exchange Act of 1934, as amended, because the number of shares of Common Stock into which the reporting person's warrants and shares of Preferred Stock are exercisable or convertible, as applicable, are limited, pursuant to the terms of the warrants and certificate of designations covering the Preferred Stock, to that number of shares of Common Stock which would result in the reporting person having aggregate beneficial ownership of 9.99% of the total issued and outstanding shares of Common Stock (the "Ownership Limitation"), the reporting person disclaims beneficial ownership of any and all shares of Common Stock that would cause the reporting person's aggregate beneficial ownership to exceed the Ownership Limitation. Therefore, in accordance with the Ownership Limitation, the reporting person, based upon 23,470,000 shares of common stock outstanding, beneficially owns an aggregate of 2,427,483 shares of Common Stock, and disclaims beneficial ownership of 1,748,200 shares of Common Stock.
