Item 3. Source and Amount of Funds or Other Consideration.

            Since the date of Amendment No. 7 ("Amendment No. 7") filed on
            December 30, 1999, the Issuer merged (the "Merger") with Corporate
            Technology Developments (`CTD"). Pursuant to the terms of the
            Merger, Dr. Rosenwald and certain entities controlled by Dr.
            Rosenwald received Shares.

Item 4. Purpose of Transaction.

            The Reporting Parties acquired Shares as an investment in the
            Issuer.

            Although the Reporting Parties have not formulated any definitive
            plans, they may from time to time acquire, or dispose of, Shares
            and/or other securities of the Issuer if and when they deem it
            appropriate. The Reporting Parties may formulate other purposes,
            plans or proposals relating to any of such securities of the Issuer
            to the extent deemed advisable in light of market conditions,
            investment policies and other factors.

            The Schedule 14A filed by the Issuer on April 30, 2002, included,
            among other things, a proposal for reelection of the nine incumbent
            directors of the Issuer at the Annual Meeting of Stockholders to be
            held on May 23, 2002 (the "Annual Meeting").

            On May 22, 2002, Dr. Rosenwald received a proxy request from Steven
            H. Kanzer ("Mr. Kanzer"), who, in his capacity as a shareholder,
            solicited Dr. Rosenwald's proxy at the Annual Meeting. Specifically,
            Mr. Kanzer requested that Dr. Rosenwald support an alternate slate
