ITEM 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

FINANCIAL CONDITION

Total deposits decreased by 2.4% during the second quarter of 1997.  This
decline occurred in all deposit categories.  The decline was not unexpected due
to short-term municipal and school deposits that matured in June.  Total
deposits increased by 2.0% in July but again this increase was due to
short-term deposits to be used by local school districts in August and
September.

Loans remained fairly steady during the first quarter of 1997 but increased
5.7% in the second quarter.  The Company historically experiences loan growth
in the second and third quarters of the year as borrowers' seasonal demands
increase.  No loans are held for sale at June 30, 1997.

Investment securities decreased by 23.5% during the first half of 1997.  The
funds received from maturing securities were used to fund a portion of the loan
growth during the first half of 1997.

The Company had an outstanding commitment for capital expenditures of
$1,300,000 at June 30, 1997.  The commitment is for a new branch office in
Hillsdale, Michigan.


CAPITAL RESOURCES

The Federal Reserve Board (FRB) has adopted risk-based capital guidelines
applicable to the Company.  These guidelines  require that bank holding
companies maintain capital commensurate with both on and off balance sheet
credit risks of their operations.  Under the guidelines, a bank holding company
must have a minimum ratio of total capital to risk-weighted assets of 8.0
percent.  In addition, a bank holding company must maintain a minimum ratio of
Tier 1 capital to total assets (less goodwill) of 3.0 percent for the most
highly rated bank holding companies.  All other bank holding companies are
required to maintain additional Tier 1 capital yielding a leverage ratio of 4.0
percent to 5.0 percent, depending on the particular circumstances and risk
profile of the institution.

The following table summarizes the Company's capital ratios as of June 30,
1997:


                    Tier 1 risk-based capital ratio     13.51%
                    Total risk-based capital ratio      12.48%
                    Leverage ratio                       9.72%


The table above indicates that the Company's capital ratios are above the
regulatory minimum requirements.

RESULTS OF OPERATIONS

Net Interest Income

Net interest income increased by $328,000 and $543,000 for the three and six
month periods ended June 30, 1997 compared to the same period in 1996.  This
increase is due to an improvement in net interest margin as a result of the
movement of funds from the securities portfolio to the loan portfolio and to
loan rates rising at a faster pace than the rates paid on deposit accounts.

Provision for Loan Losses

The provision for loan losses is based on an analysis of outstanding loans.  In
assessing the adequacy of the allowance, management reviews the characteristics
of the loan portfolio in order to determine the overall quality and risk
profile.  Some factors considered by management in determining the level at
which the allowance is maintained include a continuing evaluation of those
loans identified as being subject to possible problems in collection, results
of examinations by regulatory agencies, current economic conditions and
historical loan loss experience.



                                      6
   7

The provision for loan losses decreased by $84,000 for the six month period
ended June 30, 1997 compared to the same period in 1996.  This decrease
occurred as a result of the low level of loan losses experience in recent
years.  The allowance for loan losses is being maintained at a level which, in
management's opinion, is adequate to absorb possible loan losses in the loan
portfolio as of June 30, 1997.

Non-interest Income

Non-interest income, which includes service charges on deposit accounts, trust
fee income, security gains and losses and other miscellaneous charges and fees
increased by  $205,000 and $314,000 during the three and six month periods
ended June 30, 1997 compared to the same periods in 1996.  This increase is due
to increased service charges on deposit accounts in 1997 as a result of the
additional deposits purchased in connection with the acquisition of two
branches in late 1996,  increased gains on sale of secondary market real estate
mortgage loans in 1997 and unrealized losses on mortgage loans held for sale
recorded in 1996.  Increased fees from our Investment Center of $29,000 over
the same period in 1996 also contributed to our success in the first six months
of 1997.

Non-interest Expense

Non-interest expense increased by $334,000 and $586,000 for the three and six
month periods ended June 30, 1997 compared to the same periods in 1996.  This
increase is due to additional personnel costs, occupancy costs, marketing and
advertising expenditures and training costs resulting from the acquisition of
two branch offices late in 1996.
