Share is convertible into the number of shares of Common Stock determined by
dividing $100.00 by the Conversion Price at the time of conversion. The
Conversion Price is defined as 85% of the average of the lowest three intra-day
trading prices of the Common Stock during the 10 trading days preceding the
conversion, rounded to the nearest ten-thousandth; providing, however, that the
Conversion Price may not be less than $0.05 or more than $0.1967 adjusted for
stock splits and similar events. MPF purchased the Series A Shares from the
Issuer, and MPF and MAG received the Warrants from the Issuer, on October 18,
2004.

      The documentation governing the terms of the warrants and the Series A
Shares contains provisions prohibiting any exercise of the warrants or
conversion of Series A Shares that would result in the Reporting Persons owning
beneficially more than 9.99% of the outstanding shares of Common Stock as
determined under Section 13(d) of the Securities Exchange Act of 1934. The
Reporting Persons have never had beneficial ownership of more than 9.99% of the
outstanding shares of Common Stock.

Issuer:

      MPF owned 12,000 Series A Shares and warrants to purchase up to 3,660,396
shares of Common Stock.

owned by MPF are shared among MPF and both MAG and David F. Firestone. The right
to vote and the right to dispose of the shares beneficially owned by MAG are
