          (a)  The term "Change in Control" means (i) any "person", as such 
term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 
1934, as amended (the "Exchange Act") (other than Pinnacle, Pinnacle Bank, 
any of their affiliates, any person (as hereinabove defined) acting on behalf 
of Pinnacle and/or Pinnacle Bank as underwriter pursuant to an offering who 
is temporarily holding securities in connection with such offering, any 
trustees or other fiduciary holding securities under an employee benefit plan 
of Pinnacle and/or Pinnacle Bank, or any corporation owned, directly or

Pinnacle Bank's then outstanding securities; (ii) individuals who are members 
of the Board of Pinnacle and/or Pinnacle Bank (the "Incumbent Board") upon 
the consummation of both the IFC Merger and the CB Merger (the "Commencement 
Date") cease for any reason to constitute at least a majority thereof, 
provided that any person becoming a director subsequent to the Commencement 
Date whose election was approved by a vote of at least a majority of the 
directors comprising the Incumbent Board or whose nomination for election by 
stockholders was approved by the nominating committee serving under an 
Incumbent Board, shall be considered a member of the Incumbent Board; (iii) 
the stockholders of Pinnacle and/or Pinnacle Bank approve a merger or 
consolidation of Pinnacle and/or Pinnacle Bank with any other corporation, 
other than (1) a merger or consolidation which would result in the voting 
securities of Pinnacle outstanding immediately prior thereto continuing to 
represent (either by remaining outstanding or by being converted into voting 
securities of the surviving entity) more than 50% of the combined voting 
power of the voting securities of Pinnacle or such surviving entity 
outstanding immediately after such merger or consolidation, or (2) a merger

securities; or (iv) the stockholders of Pinnacle and/or Pinnacle Bank approve 
a plan of complete liquidation of Pinnacle and/or


<PAGE>

Pinnacle Bank or an agreement for the sale or disposition by Pinnacle and/or 
Pinnacle Bank of all or substantially all of the assets of Pinnacle and/or 
Pinnacle Bank (or any transaction having a similar effect).  Notwithstanding 
the foregoing or anything to the contrary, neither the IFC Merger nor the CB 
Merger shall constitute a "Change in Control" for purposes of this Agreement.

          (b)  The term "Good Reason" means the occurrence, without the 
Executive's express written consent, of a material diminution of or 
interference with the Executive's duties, responsibilities or benefits, 
including, without limitation, any of the following circumstances unless such 
circumstances are fully corrected prior to the Date of Termination specified 
in the Notice of Termination given by the Executive in respect thereof:

       (1)     a requirement that the Executive be principally
               based at any location not within 25 miles of St.
               Joseph, Michigan, or that he substantially increase
               his travel on Pinnacle or Pinnacle Bank business:

       (2)     a material demotion of the Executive;

       (3)     a material reduction in the number or seniority of
               personnel reporting to the Executive or a material
               reduction in the frequency with which, or in the
               nature of the matters with respect to which such
               personnel are to report to the Executive, other
               than as part of a company-wide reduction in staff;

       (4)     a reduction in the Executive's salary or a material
               adverse change in the Executive's perquisites,
               benefits, contingent benefits or vacation, other
               than as part of an overall program applied
               uniformly and with equitable effect to all members
               of the senior management of Pinnacle or Pinnacle
               Bank;

       (5)     a material and extended increase in the required
               hours of work or the workload of the Executive; or

       (6)     the failure of Pinnacle or Pinnacle Bank to obtain
               a satisfactory agreement from any successor to
               assume the obligations and liabilities under this
               Agreement, as contemplated in Section 16 hereof.


<PAGE>

          (c)  The terms "Termination for Cause" or "Cause" in relation to a 
termination of employment shall mean termination because of the Executive's 
intentional or persistent failure to perform stated duties of a material 
nature, personal dishonesty which results in material loss to Pinnacle or 
Pinnacle Bank, willful violation of any law, rule, regulation (other than 
traffic violations or similar offenses) or final cease and desist order which 
results in material loss to Pinnacle or Pinnacle Bank, or any material breach 
of this Agreement.  For purposes of this Section, no act, or the failure to 
act, on Executive's part shall be "willful" unless done, or omitted to be 
done, not in good faith and without reasonable belief that the action or 
omission was in the best interest of Pinnacle or Pinnacle Bank.  
Notwithstanding the foregoing, Executive shall not be deemed to have been 
terminated for Cause unless and until there shall have been delivered to him 
a Notice of Termination which shall include a copy of a resolution duly 
adopted by the affirmative vote of not less than a majority of the members of 
the Board of Pinnacle (excluding the Executive for purposes of said 
computation) at a meeting of the Board called and held for that purpose 
(after reasonable notice to Executive and an opportunity for him, together 
with counsel, to be heard before the Board), finding that in the good faith 
opinion of the Board, Executive was guilty of conduct justifying termination 
for Cause and specifying the particulars thereof in detail.

2.   DESCRIPTION OF SERVICES.

     Following the consummation of both the IFC Merger and the CB Merger, 
Executive shall serve as an employee of Pinnacle and/or Pinnacle Bank, in 
such capacity as may be mutually agreed by Pinnacle and/or Pinnacle Bank and 
Executive.  As an employee of Pinnacle and/or Pinnacle Bank, Executive will 
provide Pinnacle and its affiliates with the benefit of his special 
knowledge, skill, contacts and business experience in the banking, savings 
and loan, and financial services industries.

3.   AT WILL EMPLOYMENT.

     Executive shall be employed as an "at will " employee, and said 
employment may be terminated by either Pinnacle and/or Pinnacle Bank or 
Executive at any time, whether for "Cause" or any reason whatsoever, subject 
to the provisions of Sections 4, 5, 6 and 8 of this Agreement.

As used in Sections 4(a) and (b) of this Agreement, an "Event of Termination 
Prior to a Change in Control" shall mean termination of employment service in

pay or liquidated damages, or both, the sum of $156,000.

5.   PAYMENTS TO EXECUTIVE UPON AN EVENT OF TERMINATION UPON OR FOLLOWING A 
     CHANGE IN CONTROL.

     Subject to the provisions of Section 6 of this Agreement:

     (a)  In the event that Pinnacle and/or Pinnacle Bank shall terminate the 
Executive's employment other than Termination for Cause, or the Executive 
shall terminate his employment for Good Reason, or the Executive's employment 
shall be terminated by retirement, death or disability, in any said case upon

          (2)  299% of the Executive's "base amount" as determined
               under Section 280G of the Internal Revenue Code of

               the Executive, arising under any other plans or

               Pinnacle or Pinnacle Bank or any of their
               affiliates and the Executive, which are contingent
               upon a Change in Control and which are not deemed
               to be "reasonable compensation" under Section 280G
               of the Code, or
