NOTES TO FINANCIAL STATEMENTS

Note 1-Basis of Presentation

The consolidated financial statements include the accounts of CNB Corporation
("Company") and its wholly owned subsidiary, Citizens National Bank of Cheboygan
("Bank") and the Bank's wholly owned subsidiary CNB Mortgage Corporation. All
significant intercompany accounts and transactions are eliminated in
consolidation. The statements have been prepared by management without an audit
by independent certified public accountants. However, these statements reflect
all adjustments (consisting of normal recurring accruals) and disclosures which
are, in the opinion of management, necessary for a fair presentation of the
results for the interim periods presented and should be read in conjunction with
the notes to the consolidated financial statements included in the CNB
Corporation's Form 10-K for the year ended December 31, 2002.

Certain information and footnote disclosures normally included in financial
statements prepared in accordance with accounting principles generally accepted
in the United States of America have been condensed or omitted pursuant to the
rules and regulations of the Securities and Exchange Commission.

Because the results of operations are so closely related to and responsive to
changes in economic conditions, the results for any interim period are not
necessarily indicative of the results that can be expected for the entire year.

Stock Compensation: The following proforma information presents net income and
basic and diluted earnings per share had the fair value method been used to
measure compensation for stock options granted. The exercise price of options
granted is equivalent to the market price of the underlying stock at the stock
grant date; therefore no compensation expense has been recorded for stock
options granted.

In future years, as additional options are granted, the proforma effect on net
income and earnings per share may increase. Stock options are used to reward
certain officers and provide them with an additional equity interest. Options
are issued for 10 year periods and have varying vesting schedules. Information
about options available for grant and options granted follows:

Note 2-Earnings Per Share

outstanding. Diluted earnings per share will reflect the potential dilution of
stock options and other common stock equivalents. For the three and six month
period ending June 30, 2003 the weighted average shares outstanding in
calculating basic earnings per share were 1,186,655 and 1,187,479 while the
weighted average number of shares for diluted earnings per share were 1,188,999
and 1,190,573. For the three and six month period ending June 30, 2002 the
weighted average shares outstanding in calculating basic earnings per share were
1,193,163 and 1,193,203 while the weighted average number of shares for diluted
earnings per share were 1,198,622 and 1,198,662.

LOANS

Loans at June 30, 2003 decreased $1.4 million from December 31, 2002. The table
below shows total loans outstanding by type, in thousands of dollars, at June
30, 2003 and December 31, 2002 and their percentages of the total loan
portfolio. All loans are domestic. A quarterly review of loan concentrations at
June 30, 2003 indicates the pattern of loans in the portfolio has not changed
significantly. There is no individual industry with more than a 10%
concentration. However, all tourism related businesses, when combined, total
10.8% of total loans.

The Company has had no impaired loans during 2003 and 2002.

CREDIT QUALITY

The Company maintains a high level of asset quality as a result of actively
managing delinquencies, nonperforming assets and potential loan problems. The
Company performs an ongoing review of all large credits to watch for any
deterioration in quality. Nonperforming loans are comprised of: (1) loans
accounted for on a nonaccrual basis; (2) loans contractually past due 90 days or
more as to interest or principal payments (but not included in nonaccrual loans
in (1) above); and (3) other loans whose terms have been renegotiated to provide
a reduction or deferral of interest or principal because of a deterioration in
the financial position of the borrower (exclusive of loans in (1) or (2) above).
The aggregate amount of nonperforming loans is shown in the table below.



                                                       June 30,               December 31,

DEPOSITS

Deposits at June 30, 2003 increased $11.1 million since December 31, 2002. The
growth can be attributed to seasonal activity which allowed an $11.0 million
increase in noninterest bearing deposits.


LIQUIDITY AND FUNDS MANAGEMENT

As of June 30, 2003, the Company had $14.3 million in federal funds sold, $57.7
million in securities available for sale and $1.3 million in held to maturity
securities maturing within one year. These sources of liquidity are supplemented
by new deposits and loan payments received by customers. These short-term assets
represent 32.3% of total deposits as of June 30, 2003.

Total equity of the Company at June 30, 2003 was $25.6 million compared to $24.7
million at December 31, 2002.


RESULTS OF OPERATIONS

CNB Corporation's 2003 net income for the first six months was $2.0 million an
increase of $29,000 compared to the same period in 2002. Basic earnings per
share were $1.66 compared to $1.62 for 2002. The return on average assets was
1.58% compared to 1.65% for 2002. The return on average equity was 15.49%
compared to 16.18% for 2002.

Net income for the three months ending June 30, 2003 was $978,000 compared to
$908,000 for 2002. This was an increase of $ 70,000 or 7.7%. Basic earnings per
share were $0.82 compared to $0.76 for 2002. The return on average assets was
1.57% compared to 1.55% for 2002. The return on average equity was 15.40%
compared to 15.16% for 2002.

For the first six months of 2003, net interest income was $5.1 million an
increase of $560,000 or 12.4% compared to 2002 results. The Corporation
experienced a decline in both interest income and interest expenses compared to
2002 results which can be attributed to a continuing decline in the rate
environment. The decline in interest expense on deposits exceeded the decline in
overall interest income which resulted in an overall increase in the net
interest income. The Company reported a strong net interest margin of 4.32% for
2003 compared to 4.07% for 2002. Net interest income for the 3 month period
ending June 30, 2003 was $2.5 million compared to $2.3 million for 2002. Again
the decline in interest expense on deposits exceeded the decline in overall
interest income.

Noninterest income for the six month period ending June 30, 2003 was $957,000
an increase of $154,000 or 19.2% over the same period last year. This
can be attributed to an increase in the fee income as a result of increasing
sales of mortgages to the secondary market. Noninterest income for the three
month period ending June 30, 2003 was $510,000 compared to $392,000 for 2002.
Again the increase in sales to the secondary market was the reason for the
increase. The increase in the sales to the secondary market can be attributed to
increasing refinancing activity.

Noninterest expense for the six month period ending June 30, 2003 was $3.3
million compared to $2.7 million for 2002. This is an increase of $617,000, or
23.3%. Most of the increase can be attributed to a change in the discount rate
for the calculation of the annual expense for the 1985 directors deferred
compensation plan as well as the Company's pension plan. During 2002, the
Company received life insurance proceeds amounting to $105,000 which reduced
noninterest expense.

ITEM 3-QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary source of market risk for the financial instruments held by the
Company is interest rate risk. That is, the risks that an adverse change in
market rates will adversely affect the market value of the instruments.
Generally, the longer the maturity, the higher the interest rate risk exposure.
While maturity information does not necessarily present all aspects of exposure,
it may provide an indication of where risks are prevalent.

All financial institutions assume interest rate risk as an integral part of
normal operations. Managing and measuring interest rate risk is a dynamic,
multi-faceted process that ranges from reducing the exposure of the Company's
net interest margin to swings in interest rates, to assuring sufficient capital
and liquidity to support future balance sheet growth. The Company manages
interest rate risk through the Asset Liability Committee. The Asset Liability
Committee is comprised of bank officers from various disciplines. The Committee
establishes policies and rates which lead to prudent investment of resources,
the effective management of risks associated with changing interest rates, the
maintenance of adequate liquidity, and the earning of an adequate return of
shareholders' equity.

Management believes that there has been no significant changes to the interest
rate sensitivity since the presentation in the December 31, 2002 Management
Discussion and Analysis appearing in the December 31, 2002 10-K.
