                              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
engaged  Delano  to  act  as  our  exclusive  sales  agent to sell an additional
1,000,000 shares of our common stock. On March 25, 2002, we entered into a third
amendment  (the "Third Amendment") with Delano whereby we have engaged Delano to
act  as  our  exclusive  sales agent to sell an additional 323,972 shares of our
common  stock.  Except for the number of shares of common stock to be sold under
the  Delano  Agreement,  the  Amendment,  and  the  Second  Amendment, the Third
Amendment does not alter the terms of the Delano Agreement and the Amendment. We
will  settle  the  transactions  contemplated by the Third Amendment, 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  323,972  shares of common stock to be sold pursuant to this prospectus
supplement  are  registered  pursuant  to  our  registration  on  Form S-3 dated
December  1,  2000  (File  #  333-51076).




                           MARKET FOR OUR COMMON STOCK

     On March 21, 2002, the last reported sales price of our common stock on the
American  Stock  Exchange  was  $0.47  per  share.  As of March 21, 2002, we had
34,443,978  shares  of  common  stock  issued  and  outstanding.
