     980,000 Shares were acquired pursuant to a private transaction closing on

     A convertible promissory note in the principal amount of $50,000 (the

The Shares subject to this grant are exercisable pursuant to the terms of the
Notice of Stock Option Award at a purchase price of $0.10 per share.  The
Reporting Person is fully vested in the Option (as defined below), which is
xercisable by him in accordance with the schedule described in Footnote 1.
The Reporting Person paid no cash consideration for such Option.

     Except as otherwise discussed below, the Reporting Person does not
beneficially own any other securities of the Corporation.


Item 4.  Purpose of Transaction.

     As previously discussed, a Note in the principal amount of $50,000 was

making the Note currently convertible into 50,000 shares of Common Stock.  The
$50,000 used to purchase the Note came from the personal savings of the
Reporting Person.

     On December 31, 2003, the Corporation's board of directors approved
certain modifications to current equity arrangements with the Reporting Person.
In consideration for these modifications, the Corporation's board of directors
approved the issuance of an option to purchase up to 7,000,000 Shares at an
exercise price of $0.10 per share (the "Option"), which expires on December 31,
2018.  The Shares subject to this grant are exercisable pursuant to the terms
of the Notice of Stock Option Award at a purchase price of $0.10 per share.
The Reporting Person is fully vested in the Option, which is exercisable by
him in accordance with the schedule described in Footnote 1.

                                    4


On December 31, 2003, the Corporation's board of directors also approved
certain modifications to the Reporting Person's Common Stock Purchase

with these modifications, the Reporting Person agreed to relinquish certain
rights to purchase additional Shares granted pursuant to the Stock Purchase
Agreement, and entered into a certain Bonus and Other Agreement, dated
December 31, 2003 with the Corporation (the "Bonus Agreement").  In addition,
the parties agreed that Reporting Person had the right to purchase 2,767,278
