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.

        (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.

        (c)    Number of shares as to which such person has:

               (i)  Sole power to vote or to direct the vote

                             5,491,008

               (ii)  Shared power to vote or to direct the vote

                             Not applicable.

               (iii)  Sole power to dispose or to direct the disposition of

                             5,491,008




               (iv)  Shared power to dispose or to direct the disposition of

                                 Not applicable.
