                              PLAN OF DISTRIBUTION

     We  entered into a Sales Agency Agreement with Delano Group Securities, LLC
("Delano")  on  April 23, 2001 (the "Delano Agreement").  Under the terms of the
Delano  Agreement,  Delano agreed to act as our exclusive sales agent, on a best
efforts  basis, to sell up to 900,000 shares of our common stock during the year
following  the  date of the Agreement.  As of December 17, 2001, Delano had sold
all  900,000  shares  subject  to the Delano Agreement.  On December 1, 2001, we
entered  into  an  amended and restated Agreement (the "Amendment"), pursuant to
which  Delano  has agreed to act as our exclusive sales agent, on a best efforts
basis,  to  sell  up  to 1,000,000 shares of our common stock in addition to the
900,000  already sold under the Delano Agreement.  The other terms of the Delano
Agreement  are  not  affected  by the Amendment.  The common stock is to be sold
during  one  or  more  pricing  periods,  each  pricing period to consist of one
business  day.  The  net  proceeds to us from the sale of common stock by Delano
during  a  particular  pricing  period will equal 95% of the weighted average of
sales  prices of the common stock sold during that pricing periods (the "average
market  price"), less brokerage fees, service charges, and SEC transaction fees,
multiplied by the number of average market price shares sold during that pricing
period.  Therefore,  the  compensation that Delano will receive for the sales of
our  common  stock during a pricing period will equal the difference between the
aggregate  gross sales prices at which sales are actually effected by Delano and
the  net  proceeds described above. We will settle the transactions contemplated
by the Delano Agreement, including the issuance of shares of our common stock in
exchange  for  the  purchase  price,  on  the  third business day following each
pricing  period.

     The 1,000,000 shares of common stock to be sold pursuant to this prospectus
supplement  were  previously  the  subject  of  the  October 15, 2001 prospectus
supplement.  Under  the October 15, 2001 prospectus supplement, 2,000,000 shares
of  common  stock  were to be sold pursuant to the Purchase Agreement we entered
into  with Swartz Private Equity, LLC ("Swartz") on August 24, 2001 (the "Swartz
Agreement").  To  date,  none of the shares subject to the Swartz Agreement have
been  sold,  and  we  are  hereby  reducing  the  shares  allocated to Swartz by
1,000,000.  Please  see  the  October  15,  2001  prospectus supplement for more
information  regarding  the  Swartz  Agreement.


                           MARKET FOR OUR COMMON STOCK

     On  December 17, 2001, the last reported sales price of our common stock on
the  American  Stock  Exchange was $0.58 per share.  As of December 17, 2001, we
had  33,138,313  shares  of  common  stock  issued  and  outstanding.
