ITEM 5.  OTHER EVENTS.

         On January 27, 1997, CB Financial Corporation, a Michigan corporation
(the "Company"), and Citizens Banking Corporation, a Michigan corporation
("Citizens"), entered into an Agreement and Plan of Merger, dated as of January
27, 1997 (the "Merger Agreement").  The Merger Agreement provides for the
merger ("Merger") of a wholly-owned subsidiary of Citizens with and into the
Company, as a result of which the Company will become a wholly-owned subsidiary
of Citizens, subject to, among other customary conditions, the affirmative vote
of a majority of the outstanding voting shares of the Company and Citizens and
various regulatory approvals.

         Pursuant to the Merger Agreement, each outstanding share of the
Company's common stock, par value $7.50 per share (the "Company Common Stock"),
will be exchanged for 1.489 shares of Citizens common stock.

         The foregoing description of the Merger Agreement is qualified in its
entirety by reference to the Merger Agreement, which is attached hereto as
Exhibit 2.1 and is incorporated herein by reference.

         In connection with the execution of the Merger Agreement, the Company
and Citizens entered into a Stock Option Agreement, dated as of January 27,
1997 (the "Option Agreement"), pursuant to which the Company granted Citizens
the right to purchase up to 19.9% of the shares of Company Common Stock at a
price of $37.66 per share upon the occurrence of certain events described
therein relating generally to the acquisition of the Company by a third party.

         The foregoing description is qualified in its entirety by reference to
the Option Agreement, a copy of which is attached hereto as Exhibit 2.2 and is
incorporated herein by reference.

      In connection with the execution of the Merger Agreement, the Company
amended its bylaws (as amended, the "Bylaws") to provide that Chapter 7B of the
Michigan Business Corporation Act does not apply to any "control share
acquisition" (as such term is defined in Chapter 7B of the Michigan Business
Corporation Act) of shares of the Company.

      The foregoing description is qualified in its entirety by reference to
the Bylaws, which are attached hereto as Exhibit 3 and are incorporated herein
by reference.
