ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         See response to Item 4, "Purpose of Transaction."

ITEM 4. PURPOSE OF TRANSACTION

         The filing of this Amendment No. 12 to Schedule 13D is a result of the
Trust and the Company entering into a December 31, 2002 Subscription Agreement
(the "Subscription") pursuant to which the Company issued to the Trust a 9.5%
Convertible Note dated December 31, 2002 (the "Note") in the amount of Three
Million Nine Hundred Forty-Nine Thousand Nine Hundred Ninety-Six and 05/100
Dollars ($3,949,996.05), which the Trust may elect to convert into Eleven
Million Two Hundred Eighty-Five Thousand Seven Hundred Three (11,285,703) shares
of Common Stock at a conversion price of $0.35 per share. In connection with the
Subscription and the Note, the Company also issued to the Trust a Warrant to
Purchase Shares of Common Stock for Nine Hundred Eighty-Seven Thousand Five
Hundred (987,500) shares of Common Stock (the "Warrant"). The Trust may elect to
exercise the Warrant at a price of $0.35 per share. Mr. Crabbe and the Trust
have purchased these shares for investment purposes from personal funds. Mr.
Crabbe and the Trust do not have any present plans or proposals with respect to
the Common Stock. The Note cancelled and replaced various short-term
non-convertible notes that the Company had previously issued to the Trust.
