     This supplement  reflects the transfer of shares and warrants  purchased by
our former President, CEO and director to Mark Godsy, our Chairman of the Board,
on May 24, 2002.  In December  2001,  the Board of  Directors  agreed to advance
$90,000  to  Mr.  Robertson  to  enable  him to  subscribe  for  500,000  units,
consisting  of one share of common stock and one common stock  purchase  warrant
per unit,  in  conjunction  with a private  placement  completed on December 24,
2001.  The loan  principal  plus  interest is due on December  24,  2003,  bears
interest at 4% per annum and is secured by the subscribing shares. Mr. Robertson
has  subsequently  left our employment and the units as well as all  obligations
under the loan were  transferred to Mr. Godsy on May 24, 2002. On maturity,  the
loan and all interest  owing on the loan may be repaid  either in cash or by Mr.
Godsy  transferring  to us all of the securities  comprising the units purchased
with the loan.  We are  holding the units in escrow to secure  repayment  of the
loan.
