                              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  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 shares already sold under the Delano Agreement.  On February 8, 2002, we
entered  into a second amendment (the "Second Amendment") with Delano whereby we
have  engaged  Delano  to act as our exclusive sales agent to sell an additional
1,000,000 shares of our common stock.  Except for the number of shares of common
stock  to  be  sold  under  the  Delano  Agreement and the Amendment, the Second
Amendment  does  not  alter the terms of the Delano Agreement and 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
period  (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 Second Amendment, the Amendment and 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").  Under  the January 4, 2002 prospectus supplement, 1,000,000 shares
of  our  common  stock  that were to be issued pursuant to the Swartz Agreement,
were  designated  for  issuance through our arrangement with Delano, pursuant to
the  Amendment.  This  prospectus  supplement  allocates the remaining 1,000,000
shares  under  the Swartz Agreement to Delano, pursuant to the Second Amendment.
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 and the January 4, 2002 prospectus
supplement  for  more  information  regarding  the  Swartz  Agreement.



                           MARKET FOR OUR COMMON STOCK

     On  March 5, 2002, the last reported sales price of our common stock on the
American  Stock  Exchange  was  $0.56  per  share.  As  of March 5, 2002, we had
33,993,850  shares  of  common  stock  issued  and  outstanding.
