                              PLAN OF DISTRIBUTION


     We  entered  into  a  Purchase  Agreement  with  Swartz Private Equity, LLC
("Swartz") on August 24, 2001 (the "Swartz Agreement"), pursuant to which we may
offer to Swartz through a series of puts, and Swartz must purchase, from time to
time,  a  maximum of 2,000,000 shares of our common stock during the term of the
Swartz  Agreement.  We are limited as to the number of shares of common stock we
may  issue  during  each put.  This limit is equal to the sum of two put limits;
one  for each of two consecutive ten (10) business day pricing periods beginning
on  the  day following the date that we initiate a put of shares to Swartz.  The
first  put  limit  is equal to the lesser of (i) 15% of the sum of the aggregate
daily  reported  trading  volumes  in  our  common  stock  on the American Stock
Exchange  (excluding  certain block trades in excess of 20,000 shares made by us
or  any  of  our  affiliates)  for  all  business days in the first ten (10) day
pricing  period for the put, (ii) the amount of shares we indicate we would like
to  include  in that put; and (iii) the number of shares when, multiplied by the
put  price  per  share,  equals $2 million. The second put limit is equal to the
lesser  of (i) 15% of the sum of the aggregate daily reported trading volumes in
our  common stock on the American Stock Exchange (excluding certain block trades
in excess of 20,000 shares made by us or any of our affiliates) for all business
days  in  the pricing period for that put, (ii) the amount of shares we indicate
we would like to include in that put, less the limit in our first put; and (iii)
the  number  of  shares  when,  multiplied  by  the  put price per share, equals
$2,000,000  (less  the  purchase  price of any shares to be sold pursuant to the
first  ten  (10)  day  pricing  period).

     The  price  Swartz will pay for each share of common stock sold in a put is
equal  to the lesser of (i) the market price for each of the two consecutive ten
business day periods beginning on the business day immediately following the day
we  invoked  the put right minus $0.10, or (ii) 93% of the market price for each
of the two ten day periods.  Market price is defined as the average of the three
(3)  lowest  Volume  Weighted  Average  Prices  ("VWAPs")  published  daily  by
Bloomberg,  Inc.,  of  the  Company's  Common  Stock during each of the ten (10)
Business  Day pricing periods.  However, the purchase price may not be less than
the  designated  minimum per share price, if any, that we may specify in our put
notice.  The  first  pricing  period,  which  applies  to  the  number of shares
issuable  under  the  first  put limit, begins on the business day after the put
date, and ends on the tenth business day after that put date. The second pricing
period,  which  applies  to  the  number of shares issuable under the second put
limit,  begins  on  the eleventh business day after the put date and ends on the
twentieth  business  day  after  the  put  date.

     We  may  also,  for  any  put,  designate a maximum dollar amount of common
stock,  not  to  exceed  $2,000,000, that we will sell during that put, and/or a
minimum  purchase price per share for that put.  However, the designated minimum
purchase  price  for  a put may not be greater than the lesser of (i) 85% of the
closing  bid price of our common stock on the business day immediately preceding
the  date  on  which  we give advance notice of the put and (ii) the closing bid
price  of our common stock on the business day immediately preceding the date on
which  we  give  advance  notice  of  the  put,  less  $0.15.



     Limitations  and  Conditions  Precedent  to  Our  Put  Rights.  We  may not
initiate  a  put  if,  as  of  the  proposed  date  of  such  put:

     1.     We  have  issued  shares  of  our  common stock equal to the maximum
offering amount  that  have  been  paid  for  by  Swartz;

     2.     The registration statement covering the resale of the shares becomes
ineffective  or  unavailable  for  use;  or

     3.     Our  common stock is not actively trading on the OTC Bulletin Board,
the  Nasdaq  Small  Cap  Market,  the Nasdaq National Market, the American Stock
Exchange,  or  the  New  York  Stock  Exchange, or is suspended or delisted with
respect  to  the  trading  on  such  market  or  exchange.

     If  any  of the following events occur during the pricing period for a put,
the  volume  accrual  shall  cease.  The  pricing  period  for  the put shall be
adjusted  to  end ten (10) business days after the date that we notify Swartz of
the  event,  and any minimum price per share we specified shall not apply to the
put:

     1.     We have announced or implemented a stock split or combination of our
common  stock  between  the  advanced put notice date and the end of the pricing
period;

     2.     We  have paid a common stock dividend or made any other distribution
of  our  common  stock  between  the advanced put notice date and the end of the
pricing  period;

     3.     We have made a distribution to the holders of our common stock or of
all  or  any  portion of our assets or evidences of indebtedness between the put
notice  date  and  the  end  of  the  pricing  period;

     4.     We  have  consummated  a major transaction (including a transaction,
which  constitutes  a change of control) between the advance put notice date and
the end of the pricing period, the registration statement covering the resale of
the  shares  becomes  ineffective  or  unavailable for use, or our stock becomes
delisted  for  trading  on  our  then  primary  exchange;  or

     5.     We discover the existence of facts that cause us to believe that the
registration  statement  of  which  this prospectus is a part contains an untrue
statement  or  omits  to  state  a  material  fact.


     Our  right  to  initiate  puts will terminate automatically and immediately
upon  the  occurrence  of  any  of the following events: (i) if we or any of our
directors or executive officers engage in a transaction or conduct which results
in  an SEC enforcement action or criminal or certain civil liability; (ii) after
an  aggregate  of four months of periods during which the registration statement



incorporating  the  prospectus  is not effective or our common stock is delisted
from  the  American  Stock  Exchange;  (iii) we are the subject of a bankruptcy,
insolvency  or  similar proceeding; (iv) after the sooner of (x) 18 months after
the date of the Swartz Agreement or (z) the date on which we have made aggregate
puts  of  common  stock in the amount of 2,000,000 shares; and (v) our breach of
certain  covenants  in  the  Swartz  Agreement.

     We  have  also  agreed  to  issue to Swartz three-year warrants to purchase
shares  of our common stock.  The warrants are to be issued within five business
days  after  the  end  of the second pricing period for each put.  The number of
shares  of our common stock underlying each warrant will equal 10% of the amount
of  shares  in  the  applicable put, and the exercise price per share will equal
125%  of  the  put  share  price  for  the  applicable  put.


                           MARKET FOR OUR COMMON STOCK

     On  October  12, 2001, the last reported sales price of our common stock on
the American Stock Exchange was $0.71 per share.  As of October 12, 2001, we had
30,931,271  shares  of  common  stock  issued  and  outstanding.
