    The
      Corporation is authorized to issue
      more than one class of stock, including a class of preferred stock which may
      be
      issued in one or more series. The Corporation will furnish to any stockholder,
      upon written request and without charge, a full statement of the designations,
      preferences, limitations and relative rights of the shares of each class
      authorized to be issued and, with respect to the issuance of any preferred
      stock
      to be issued in series, the relative rights, preferences and limitations between
      the shares of each series so far as the rights, preferences and limitations
      have
      been fixed and determined and the authority of the Board of Directors to fix
      and
      determine the relative rights, preferences and limitations of subsequent
      series.

               
      The Articles of Incorporation of the Corporation includes a provision which
      generally prohibits any person (including an individual, company or group acting
      in concert) from directly or indirectly offering to acquire or acquiring the
      beneficial ownership of more than 10% of any class of equity securities of
      the
      Corporation. In the event that stock is acquired in violation of this 10%
      limitation, the excess shares will no longer be counted in determining the
      total
      number of outstanding shares for purposes of any matter involving stockholder
      action and the Board of Directors of the Corporation may cause such excess
      shares to be transferred to an independent trustee for sale in the open market
      or otherwise, with the expenses of such sale to be paid out of the proceeds
      of
      the sale.

               
      The Articles of Incorporation of the Corporation contains provisions
      that
      the affirmative vote of at least 80% of the Voting Shares (as defined) may
      be
      required to approve certain business combinations and other
      actions.
