                    Islands company ("SF Capital"). The Reporting Persons are

                    Based upon the 16,171,067 shares of Common Stock issued and
                    outstanding as of November 30, 2003 (as set forth in the
                    Issuer's quarterly report on Form 10-Q for the fiscal
                    quarter ended November 30, 2003) and 2,585,965 shares of
                    Common Stock issued in connection with an offering by the
                    Issuer (as set forth in the Issuer's Form 424B2 filed on
                    January 26, 2004), for the purposes of Rule 13d-3 under the
                    Securities Exchange Act of 1934, the Reporting Persons may
                    be deemed to be the beneficial owners of 1,571,915 shares of
                    Common Stock which represents 8.4% of the Issuer's issued
                    and outstanding shares of Common Stock. The beneficial
                    ownership of the Reporting Persons excludes certain options
                    held by the Reporting Persons which the Reporting Persons
                    are contractually restricted from exercising at this time.
                    The Reporting Persons cannot exercise such options so long
                    as the Reporting Persons would be deemed "beneficial owners"
                    of more than 9.99% of the Common Stock following such
                    conversion.
