                              PLAN OF DISTRIBUTION


     We  entered into a Sales Agency Agreement with Delano Group Securities, LLC
("Delano")  on April 23, 2001 (the "Agreement"), pursuant to which Delano agreed
to  act as our exclusive sales agent, on a best efforts basis, for up to 900,000
shares  of our common stock during the year following the date of the Agreement.
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 sale 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 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.


                           MARKET FOR OUR COMMON STOCK

     On  May  1,  2001, the last reported sales price of our common stock on the
American  Stock  Exchange  was  $2.08  per  share.  As  of  May  1, 2001, we had
28,782,202  shares  of  common  stock  outstanding.
