NOTES TO CONSOLIDATED 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 the
consolidation process. 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, 2004.

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. FAS123R will be effective in 2006 and requires companies to
record compensation for stock options provided to employees in return for
employee service. The cost is measured at the fair value of the options when
granted, and this cost is expensed over the employee's service period, which is
normally the vesting period of the options. This will apply to awards granted or
modified after adoption. Compensation cost will also be recorded for prior
option grants that vest after the date of adoption. The effect on results of
operations will depend on the level of future option grants and the calculation
of the fair value of the options granted at such future date, as well as the
vesting periods provided, and so cannot currently be predicted.

In future years, as additional options are granted, the 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:

There have been no significant changes in the Company's critical accounting

Note 2-Earnings Per Share

Basic earnings per share are calculated solely on weighted-average common shares
outstanding. Diluted earnings per share will reflect the potential dilution of
stock options and other common stock equivalents. For the three and nine month
periods ending September 30, 2005 the weighted average shares outstanding in
calculating basic earnings per share were 1,237,305 and 1,236,562 while the
weighted average number of shares for diluted earnings per share were 1,240,083
and 1,239,223. As of September 30, 2005 there were 8,340 shares not considered
in the earnings per share calculation because they were antidilutive. For the
three and nine month periods ending September 30, 2004 the weighted average
shares outstanding in calculating basic earnings per share were 1,238,362 and
1,242,799 while the weighted average number of shares for diluted earnings per
share were 1,240,866 and 1,246,969.

LOANS

Net loans at September 30, 2005 increased $7.5 million from December 31, 2004.
The table below shows total loans outstanding by type, in thousands of dollars,
at September 30, 2005 and December 31, 2004 and their percentages of the total
loan portfolio. All loans are domestic. A quarterly review of loan
concentrations at September 30, 2005 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 13.9% of total loans.

ALLOWANCE AND PROVISION FOR LOAN LOSSES

An analysis of the allowance for loan losses, in thousands of dollars, for the
nine months ended September 30, follows:



                              2005       2004
                            --------   --------

                            =======    =======


The Company had one impaired loan during 2004 with an average balance of
approximately $100,000. The balance of this loan was zero at December 31, 2004.
The Company had no impaired loans during the first nine months of 2005.

                                       9



Since December 31, 2004, net loans have increased $7.5 million and the loan
portfolio has undergone a shift in its composition over the past nine months.
Since December 31, 2004 commercial mortgages have increased $8.2 million while
consumer mortgages have decreased $1.9 million. This is primarily due to a slow
down in residential refinancing and a stronger emphasis on commercial lending.
There has been no change in the bank's lending policies. The lending staff
continues to be well-trained and experienced. The trend and volume of past due
loans continues to be well-controlled and in line with peer averages. In
response to the change in portfolio composition and loan growth management
recorded a provision of $90,000 in the first nine months of 2005 compared to $0
for 2004.

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.



                                 September 30,  December 31,

DEPOSITS

Deposits at September 30, 2005 increased $5.8 million since December 31, 2004.
Interest-bearing deposits decreased $978,000 or less than 1% for the nine months
ended September 30, 2005, while noninterest -bearing deposits increased $6.8
million or 18.2%. This growth can be attributed to seasonal activity.

LIQUIDITY AND FUNDS MANAGEMENT

As of September 30, 2005, the Company had $5.0 million in federal funds sold,
$76.4 million in securities available for sale and $253,000 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 35.3% of total deposits as of September 30, 2005.

Total equity of the Company at September 30, 2005 was $25.0 million compared to
$24.2 million at December 31, 2004.

RESULTS OF OPERATIONS

CNB Corporation's 2005 net income for the first nine months was $2.5 million, an
increase of $182,000 compared to 2004 results. This growth and change in
composition can be attributed to an increase in net interest income resulting
from the higher rate environment compared to 2004. Earnings also include
$300,000 due to life insurance proceeds received due to death of a director. The
proceeds were offset by additional expense of $315,000 to recognize the amount
payable to the director upon death under the deferred compensation plan. Basic
earnings per share were $2.03 and diluted earnings per share were $2.02 for 2005

                                       10



compared to basic earnings per share of $1.87 and diluted earnings per share of
$1.86 for 2004. The return on assets was 1.29% for the first nine months of the
year versus 1.20% for the same period in 2004. The return on equity was 13.52%
compared to 12.26% for the same period last year.

Net income for the three months ending September 30, 2005 was $769,000 compared
to $819,000 for 2004. This was a decrease of $50,000 or 6.1%. Basic and diluted
earnings per share were $0.62 compared to $0.66 for 2004. The return on average
assets was 1.16% compared to 1.23% for 2004. The return on average equity was
12.36% compared to 13.16% for 2004. These decreases were primarily due to the
higher interest rates being paid on deposits in the third quarter 2005 as
compared to the same period in 2004.

For the first nine months of 2005, net interest income was $7.7 million
representing an increase of 7.5% from the same period in 2004. This increase can
be attributed to an increase in interest income compared to the first nine
months of 2004. The fully taxable equivalent net interest margin increased to
4.31% for the nine month period ending September 30, 2005 compared to 4.03% for
the same period ending September 30, 2004. This change can be attributable to an
increase in overall interest rates from 2005 to 2004.

Net interest income for the three months ending September 30, 2005 was $2.6
million compared to $2.5 million for the same period in 2004 representing an
increase of 4.4%. This increase is for the same reason as noted above.

In response to the change in the loan portfolio composition and loan growth
management recorded a provision expense of $90,000 in the first nine months in
2005 compared to $0 for the same period in 2004. The provision expense for the
three months ending September 30, 2005 was $30,000 and no provision expense was
recorded during the third quarter of 2004.

Noninterest income for the nine months ending September 30, 2005 was $1.4
million, an increase of $197,000 or 16.0% from the same period last year. The
majority of this increase can be attributed to income from the life insurance
proceeds as mentioned above. The increase in noninterest income due to the life
insurance proceeds was offset, in part by a decline in gains on sales of loans
due to the lesser amount of loans that were sold to the secondary market
year-to-date 2005 as compared to the same period in 2004.

For the three months ended September 30, 2005 noninterest income increase to
$401,000 as compared to $392,000 for the same period in 2004. This increase can
be attributed to increased gains on the sale of loans and increase servicing fee
income, but was offset by decreased service charge fee income.

Noninterest expense for the first nine months of 2005 was $5.6 million compared
to $5.1 million for the same period in 2004. This increase can largely be
attributed to the increase in deferred compensation expense as noted above.
Legal and professional fees increase $138,000 for the nine months ending
September 30, 2005. Some of this increase can be attributed to increased fees
from outside auditors due to additional audit requirements under Sarbanes-Oxley.
Increases in professional fees also include service costs for the addition of
internet banking and other miscellaneous professional service fees.

For the three months ended September 30, 2005, noninterest expense increased
$139,000 to $1.8 million as compared to $1.7 million for the same period in
2004. The majority of this increase can be attributed to an increase in legal
and professional fees for the same reasons as noted above.

The provision for federal income tax was 26.6% of pretax income for the nine
months ended September 30, 2005 as compared to 28.6% for the same period in
2004. The difference between the tax rates for the two periods is due to the
unanticipated non-taxable income from insurance proceeds during 2005. The
difference between the effective tax rate and the federal corporate tax rate of
34% is generally due to tax-exempt interest earned on investments and loans and
other tax-related items.

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 risk that a 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.

                                       11



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
reviews policies and establishes 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, 2004 Management
Discussion and Analysis appearing in the December 31, 2004 10K.

The Company adopted a Stock Redemption Program on November 14, 2002 with the
provision that it would remain in effect for six months or until $1 million had
been expended on the purchase of common stock, whichever shall occur first. The
Company extended the program in May 2003 until November 2003. The Company
reinstated the program on December 24, 2003 and it will remain in effect until
the $1 million originally allocated for common stock purchases is met. As of
September 30, 2005, the Company has $5 remaining to purchase stock under the
program, but due to the average price per share the Company considers the
program to have come to an end as of July 31, 2005.
