Provide the following information regarding the aggregate number and percentage of the class of securities of the issuer identified in Item 1. (a) Amount beneficially owned: 5,491,008 The Tail Wind Fund, Ltd. ("Tail Wind") beneficially owns a total of 5,491,008 shares of Common Stock, which includes: (i) 1,260,525 shares of Common Stock held, (ii) 1,570,982 shares of Common Stock into which Tail Wind's 4% Convertible Debentures (the "Debentures") are convertible, (iii) 659,501 shares of Common Stock for which Tail Wind's Purchase Warrants are exercisable, and (iv) 2,000,000 shares of Common Stock into which Tail Wind's Callable Warrants are exercisable. Each of the above calculations is determined as of December 31, 2001 based on a conversion price of the Debentures equal to $2.047 and 188 days accrued interest. 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 Debentures and warrants are convertible or exercisable, as applicable, are limited, pursuant to the terms of such instruments, to that number of shares of Common Stock which would result in the Reporting Person having aggregate beneficial ownership of 9.9% 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. (b) Percent of class: Tail Wind's aggregate beneficial ownership of 5,491,008 shares of Common Stock constitutes 8.37% of all of the outstanding shares of Common Stock, based upon 60,033,490 outstanding shares of Common Stock as of September 30, 2001 plus 1,357,867 shares issued to Tail Wind after such date and prior to December 31, 2001 plus the number of shares underlying the Debentures, Purchase Warrants and Callable Warrants.
