     In a private  placement that closed on May 31, 2000, the reporting  persons
purchased  a total of 50  units  at a price of  $100,000  per  unit.  Each  unit
consisted of 10,000 shares of Series C Preferred  Stock and Warrants to purchase
a number  of  shares of  Common  Stock  equal to 25% of the  number of shares of
Common  Stock into  which the Series C  Preferred  Stock is  convertible,  at an
initial  exercise  price of $1.50 per share.  Each  share of Series C  Preferred
Stock is  convertible  at any time  into a number  of  shares  of  Common  Stock
determined by dividing the liquidation value, by the conversion price, initially
$1.50  per   share,   which  is  subject  to   adjustment   for  stock   splits,
recapitalizations, and other similar events.

     As a  result  of  the  approval  on  September  7,  2000  by  the  Issuer's
shareholders  of  an  amendment  to  the  Issuer's   Articles  of  Incorporation
increasing its  authorized  Common Stock,  the Series C Preferred  Stock and the
Warrants became convertible and exercisable, respectively.

     The reporting persons agreed that they will not sell, transfer or otherwise

exercise of such securities  purchased in the private  placement for a period of
one year  following  the closing and  thereafter,  each  investor  may not sell,
transfer or dispose of more than 25% on a  cumulative  basis of such  securities
during each of the  following  four 90-day  periods.  The lock-up  period may be
extended  by  Commonwealth  Associates  (the  placement  agent)  for  up  to  an
additional  six  months  from  the  closing  of  any  public  offering  that  is
consummated  prior to the end of the initial lock-up period, in which case there
will be no further lock-up at the end of such period.

     The Series C Preferred Stock is automatically convertible into Common Stock

closing bid price of the Issuer's  Common Stock  exceeds 300% of the  conversion
price for 20  consecutive  trading  days,  or (b) upon a public  offering of the

Stock are  entitled to vote their  shares on all matters  submitted to a vote of
the shareholders,  on an as-converted basis with the holders of the Common Stock
as a single class,  except as required by applicable law, and except the holders
of the Series C Preferred  Stock have the right to vote separately as a class to
elect two directors to the Issuer's Board of Directors.

     The Warrants are callable for a nominal price at the Issuer's  option on 30

Common Stock for 20 consecutive trading days exceeds 300% of the exercise price,
as adjusted,  (b) the Common Stock is trading on a national  securities exchange
or Nasdaq  SmallCap or National  Market Systems or (c) a registration  statement
