                 This Agreement may be amended, modified or supplemented, or
compliance with any provision or condition hereof may be waived, at any time,
by the mutual consent of the Boards of Directors of the Company and of Holding
Company at any time prior to the time the Certificate is filed with the
Michigan Bureau; provided, however, that no such amendment, modification,
supplement or waiver shall be made or effected if such amendment, modification,
supplement or waiver would, in the sole judgment of the Board of Directors of

in its sole judgment, that consummation of the Exchange would for any reason be
inadvisable or not in the best interests of the Company or its shareholders.


                                   ARTICLE V

                 This Agreement has been submitted to the holders of Company
Common Stock and to the  sole holder of Holding Company Common Stock for
approval as provided by the Act.  The affirmative vote of the holders of a
majority of the outstanding Company Common Stock was received constituting the
adoption of this Agreement.  The affirmative vote of the holder of all of the
outstanding shares of Holding Company Common Stock was received constituting
the adoption of this Agreement.


                                   ARTICLE VI

                 Following the Effective Time, each holder of an outstanding
certificate or certificates theretofore representing shares of Company Common
Stock may, but shall not be required to, surrender the same to Holding Company
for cancellation and reissuance of a new certificate or certificates in such
holder's name or for cancellation and transfer, and each such holder or
transferee will be entitled to receive a certificate or certificates
representing the same number of shares of Holding Company Common Stock as the
shares of Company Common Stock previously represented by the certificate or
certificates surrendered.  Until so surrendered or presented for transfer, each
outstanding certificate which, immediately prior to the Effective Time,
represents Company Common Stock shall be deemed and treated for all corporate
purposes to represent the ownership of the same number of shares of Holding
Company Common Stock as though such surrender or transfer and exchange had
taken place.  The holders of Company Common Stock at the Effective Time shall
have no right to have their shares of Company Common Stock transferred on the
stock transfer books of the Company, and such stock transfer books shall be
deemed to be closed for this purpose at the Effective Time.

                                  ARTICLE VII

                 Prior to or as of the Effective Time, each director of the
Company who is not then also a director of Holding Company shall become a
director of Holding Company.  Each director of the Company as of the Effective
Time shall also remain a director of the Company.

                                  ARTICLE VIII

                 At the Effective Time, Holding Company shall adopt a dividend
reinvestment plan ("Holding Company DRIP") substantially similar to the
Company's Dividend Reinvestment Plan ("Company DRIP") in effect immediately
prior to the Effective Time and the Company DRIP shall be discontinued.  At the
Effective Time, all shares of Company Common Stock held under the Company DRIP
(including fractional and uncertificated shares) shall be converted to shares
(including fractional and uncertificated shares) of Holding Company Common
Stock and shall be held pursuant to the Holding Company DRIP.  At the Effective
Time, Holding Company shall adopt, become subject to and/or agree to issue
Holding Company Common Stock in connection with each Savings and Investment
Plan of the Company and the Company's Long-Term Incentive Plan.
