Company, sales of stock at less than the greater of market value or the Exercise
Price or other dilutive transactions. The Exercise Price of Warrants represented
by this Warrant  Certificate  is payable  either in cash or by bank draft to the
order of the  Company.  No  adjustment  shall be made for any  dividends  on any
Shares  issuable  upon  exercise of the  Warrants  represented  by this  Warrant
Certificate.

    In order to exercise  these  Warrants,  the form of election to purchase on

Share.

     Warrants  are  transferable  at the  office of the  Company  by the  Holder
thereof in person or by  attorney  duly  authorized  in  writing,  but only upon
surrender of the Warrant  Certificate and the payment of transfer taxes, if any.
Upon any such transfer, a new Warrant Certificate or new Warrant Certificates of
different  denominations  of like tenor and  representing  in the  aggregate the
right to purchase a like number of Shares,  will be issued to the  transferee in
exchange for this Warrant Certificate.

     This Warrant Certificate,  when surrendered at the office of the Company by
the Holder in person or by attorney duly authorized in writing, may be exchanged
for any other Warrant Certificates of different  denominations of like tenor and
representing in the aggregate the right to purchase a like number of Shares.

     If this Warrant  Certificate  shall be surrendered  for exercise within any
period  during  which  the  transfer  books for the  Shares or other  securities
purchasable upon the exercise of Warrants are closed for any reason, the Company
shall not be  required  to make  delivery  of  Certificates  for the  securities
purchasable  upon such exercise until the date of the reopening of said transfer
books.

     The Holder shall not be entitled to any of the rights of a  shareholder  of
the Company prior to exercise hereof.

Transfer Agent.
