NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
  (UNAUDITED)

SOUTHERN MICHIGAN BANCORP, INC. AND SUBSIDIARY

June 30, 2001


NOTE A -- BASIS OF PRESENTATION

The accompanying year-end balance sheet data was derived from audited
consolidated financial statements, but does not include all disclosures required
by generally accepted accounting principles.

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions for Form 10-Q and Rule 10-01 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. For further information, refer to the consolidated financial
statements and footnotes thereto included in the Company's annual report on Form
10-K for the year ended December 31, 2000.

Basic earnings per common share is net income divided by the weighted average
number of common shares outstanding during the period. ESOP shares are
considered outstanding for this calculation unless unearned. Diluted earnings
per common share includes the dilutive effect of additional potential common
shares issuable under stock options. Earnings and dividends per share are
restated for all stock splits and dividends through the date of issue of the
financial statements. On April 17, 2001, 10,191 options to purchase shares of
stock were granted by the Board of Directors under the 2000 Stock Option plan.

The basic and diluted weighted average common shares outstanding for the three
and six month periods ended June 30, 2001 were:

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

FINANCIAL CONDITION

Net loans have decreased by 4.6% in the first six months of 2001. The decrease
has occurred in the real estate mortgage and consumer portfolios. Customers took
advantage of the 275 basis point drop in interest rates since the beginning of
the year to refinance their adjustable rate loans or their higher rate fixed
rate loans. These longer term fixed rate loans were subsequently sold on the
secondary market. At June 30, 2001 the Company had $213,000 in loans held for
sale.

The decrease in the loan portfolio generated excess cash which allowed the
Company to reduce the long term borrowings and federal funds purchased during
the first six months of 2001.

There were no significant fixed asset commitments as of June 30, 2001.


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
equal to 4.0 percent of risk-weighted assets. Tier 1 capital includes common
shareholders' equity, qualifying perpetual preferred stock and minority interest
in equity accounts of consolidated subsidiaries less goodwill.

As a supplement to the risk-based capital requirements, the FRB has also adopted
leverage capital ratio requirements. The leverage ratio requirements establish a
minimum ratio of Tier 1 capital to total assets less goodwill of 3 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 percent to 5 percent, depending on the particular circumstances and risk
profile of the institution.





                                      -6-
   7
The following table summarizes the Company's capital ratios as of June 30, 2001:



                                                      
                  Tier 1 risk-based capital ratio             11.39%
                  Total risk-based capital ratio              12.22
                  Leverage ratio                               8.37


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


RESULTS OF OPERATIONS

Net Interest Income

Net interest income decreased by $271,000 and $385,000 for the three and six
month periods ended June 30, 2001 compared to the same periods in 2000. This
decrease is the result of a decrease in the Company's margin due to a higher
cost of funds (primarily higher rate CD's and FHLB borrowings) and six
reductions, totaling 275 basis points, in the national prime rate during the
first six months of 2001.

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.

The provision for loan losses for the first six months of 2001 was $300,000
higher than the same period of 2000. The increase is partially the result of one
commercial loan charge off of $673,000 for which $526,000 had previously been
allocated in the allowance for loan loss. The allowance for loan losses is being
maintained at a level which, in management's opinion, is adequate to absorb
probable loan losses in the loan portfolio as of June 30, 2001.





                                            -7-


   8
Non-interest Income

Non-interest income, which includes service charges on deposit accounts, gain on
sale of loans, trust fee income, security gains and losses and other
miscellaneous charges and fees, increased by $70,000 and $238,000 for the three
and six month periods ended June 30, 2001 compared to the same periods in 2000.
This increase is due primarily to gains recognized on the sale of real estate
mortgage loans to the secondary market. In order to reduce the risk associated
with changing interest rates, the Company regularly sells fixed rate real estate
mortgage loans on the secondary market. The Company recognizes a profit at the
time of sale. During a period of relatively low interest rates, the Company has
generated relatively large volumes of fixed rate mortgage loans.


Non-interest Expense

Non-interest expenses increased by $92,000 and $49,000 for the three and six
month periods ended June 30, 2001 compared to the same periods in 2000. This
increase is due primarily to a loss incurred on a repossessed mortgage property
that was sold at a loss of $52,000.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's primary market risk exposure is interest rate risk and to a lesser
extent liquidity risk. Interest rate risk arises when the maturity or repricing
characteristics of assets differ significantly from the maturity or the
repricing characteristics of liabilities. Accepting this risk can be an
important source of profitability and shareholder value, however, excessive
levels of interest rate risk could pose a significant threat to the Company's
earnings and capital base. Accordingly, effective risk management that maintains
interest rate risk at prudent levels is essential to the Company's safety and
soundness.

The Company measures the impact of changes in interest rates on net interest
income through a comprehensive analysis of the Bank's interest rate sensitive
assets and liabilities. Interest rate sensitivity varies with different types of
interest-earning assets and interest-bearing liabilities. Overnight federal
funds and mutual funds on which rates change daily and loans which are tied to
the prime rate or a comparable index differ considerably from long-term
investment securities and fixed-rate loans. Similarly, certificates of deposit
and money market investment accounts are much more interest sensitive than
passbook savings accounts. The shorter term interest rate sensitivities are key
to measuring the interest sensitivity gap, or excess interest-earning assets
over


                                      -8-

   9

interest-bearing liabilities. In addition to reviewing the interest sensitivity
gap, the Company also analyzes projected changes in market interest rates and
the resulting effect on net interest income.

Liquidity management involves the ability to meet the cash flow requirements of
customers who may be either depositors wanting to withdraw funds or borrowers
needing assurance that sufficient funds will be available to meet their credit
needs. Certain portions of the Bank's liabilities may be short-term or due on
demand, while most of its assets may be invested in long-term loans or
investments. Accordingly, the Company seeks to have in place sources of cash to
meet short-term demands. These funds can be obtained by increasing deposits,
borrowing or selling assets. Also, Federal Home Loan Bank advances and
short-term borrowings provide additional sources of liquidity for the Company.

There have been no significant changes in the distribution of the Company's
financial instruments that are sensitive to changes in interest rates during the
first six months of 2001.
