     or in securities of a corporation or otherwise.  When considering whether
     to oppose an offer, the Board of Directors may, but it is not legally
     obligated to, consider any pertinent issues; by way of illustration, but
     not of limitation, the Board of Directors may, but shall not be legally
     obligated to, consider any and all of the following:

     (1)  Whether the offer price is acceptable based on the historical and
          present operating results or financial condition of the corporation.

     (2)  Whether a more favorable price could be obtained for the corporation's
          securities in the future.

     (3)  The impact which an acquisition of the corporation would have on its
          employees, depositors and customers of the corporation and its
          subsidiaries in the community which they serve.

     (4)  The reputation and business practices of the offeror and its
          management and affiliates as they would affect the employees,
          depositors and customers of the corporation and its subsidiaries and
          the future value of the corporation's stock.

     (5)  The value of the securities, if any, which the offeror is offering in
          exchange for the corporation's securities, based on an analysis of the
          worth of the corporation as compared to the corporation or other
          entity whose securities are being offered.

     (6)  Any antitrust or other legal and regulatory issues that are raised by
          the offer.

  B. If the Board of Directors determines that an offer should be rejected, it
     may take any lawful action to accomplish its purpose including, but not
     limited to, any and all of the following:  advising shareholders not to
     accept the offer; litigation against the offeror; filing complaints with
     all governmental and regulatory authorities; acquiring the corporation's
     securities; selling or otherwise issuing authorized but unissued securities
     or treasury stock or granting options with respect thereto; acquiring a
     company to create an anti-trust or other regulatory problem for the
     offeror; and

                                       2


 
     obtaining a more favorable offer from another individual or entity.

9.   No merger, consolidation, liquidation or dissolution of the Corporation, or
     any action that would result in the sale or other disposition of all or
     substantially all of the assets of the Corporation shall be valid unless
     first approved by the affirmative vote of the holders of at least seventy-
     five percent (75%) of the outstanding shares of Common Stock.  This Article
     9 may not be amended unless first approved by the affirmative vote of the
     holders of at least seventy-five percent (75%) of the outstanding shares of
     Common Stock.

     classes, as nearly equal in number as possible, known as Class 1,
     consisting of not more than eight (8) Directors; Class 2, consisting of not

     his/her term of office as herein provided has otherwise expired, except in
     the event of his/her earlier resignation, removal or disqualification.

11.  The Board of Director shall consist of not less than five (5) nor more than
