     the date of the applicable offering), the Holder shall not, directly or
     indirectly, sell, make any short sale of, loan, hypothecate, pledge,

     any time during the Exercise Period shall, by subdivision, combination
     or re-classification of securities, change any of the securities to
     which purchase rights under this Warrant exist under the same or
     different number of securities of any class or classes, this Warrant
     shall thereafter entitle the Holder to acquire such number and kind of
     securities as would have been issuable as a result of such change with
     respect to the Warrant Shares immediately prior to such subdivision,
     combination or re-classification. If the Company's Common Stock are
     subdivided into a greater number of Common Stock the Exercise Price for
     the Warrant Shares shall be proportionately reduced and the Warrant
     Shares shall be proportionately increased; and conversely, if the
     Company's Common Stock are combined into a smaller number of Common
     Stock, the Exercise Price shall be proportionately increased, and the
     Warrant Shares shall be proportionately decreased.
