ITEM 1 - BUSINESS

CNB Corporation ("the Company") was incorporated in June, 1985 as a business
corporation under the Michigan Business Corporation Act, pursuant to the
authorization and direction of the Board of Directors of The Citizens National
Bank of Cheboygan ("the Bank").

The Company is a bank holding company registered with the Board of Governors of
the Federal Reserve System (the "Federal Reserve Board") under the Bank Holding
Company Act with the Bank as its only wholly-owned subsidiary. The Bank was
acquired by the Company effective December 31, 1985. The Company has corporate
power to engage in such activities as permitted to business corporations under
the Michigan Business Corporation Act, subject to the limitations of the Bank
Holding Company Act and regulations of the Federal Reserve Board. In general,
the Bank Holding Company Act and regulations restrict the Company with respect
to its own activities and activities of any subsidiaries to the business of
banking or such other activities which are closely related to the business of
banking.

The Bank offers a full range of banking services to individuals, partnerships,
corporations, and other entities. Banking services include checking, NOW
accounts, savings, time deposit accounts, money market deposit accounts, safe
deposit facilities and money transfers.

The Bank's lending function provides a full range of loan products. These
include real estate mortgages, secured and unsecured commercial and consumer
loans, check credit loans, lines of credit, home equity loans and construction
financing. The Bank also participates in specialty loan programs through the
Michigan State Housing Development Authority, Small Business Administration,
Federal Home Loan Mortgage Corporation, Consolidated Farm Service Agency and
Mortgage Guaranty Insurance Corporation. Through correspondent relationships,
the Bank also makes available credit cards and student loans. The Bank's loan
portfolio is over 63% residential real estate mortgages on both primary and
secondary homes. The borrower base is very diverse and loan to value ratios are
generally 80% or less. The commercial loan portfolio accounts for approximately
10% of total loans. Agricultural lending is minimal and secured by real estate.
Construction lending is predominately residential, with only an occasional
"spec" home or commercial building. Unsecured lending is very limited and
personal guarantees are required on most commercial loans.

The Bank makes first and second mortgage loans to its customers for the purchase
of residential and commercial properties. Historically, the Bank has sold its
residential mortgage loans qualifying for the secondary market to the Federal
Home Loan Mortgage Corporation ("FHLMC"). The mortgage loan portfolio serviced
by the Bank for the FHLMC totaled over $ 30 million at December 31, 1998.

Banking services are delivered through a system of five full-service banking
offices and three drive-in branches plus seven automated teller machines in
Cheboygan, Emmet and Presque Isle Counties, Michigan. The business base of the
Counties is primarily tourism with light manufacturing. The Bank maintains
correspondent bank relationships with several larger banks, which involve check
clearing operations, transfer of funds, loan participation, and the purchase and
sale of federal funds and other similar services.

Under various agency relationships, the Bank provides trust and discount
brokerage services and



                                     Page 1
<PAGE>   3

mutual fund, annuity and life insurance products to its customers.

In its primary market, which includes Cheboygan County and parts of Emmet,
Mackinac, Presque Isle and Montmorency Counties, the Bank is one of two
principal banking institutions located within this market. The competing bank is
a member of a multi-bank holding company with substantially more assets than the
Company. There are also two credit unions, one savings and loan association and
a brokerage firm. The Bank is the only independent community bank in the
Cheboygan County market.

As of December 31, 1998, the Bank employed 66 full-time and 14 part-time
employees. This compares to 64 full-time and 17 part-time employees as of
December 31, 1997. The Company has no full-time employees. Its operation and
business are carried out by officers and employees of the Bank who are not
compensated by the Company.

The review of the loan portfolio revealed no undue concentrations of credit,
however, the portfolio continues to be highly concentrated in residential real
estate mortgages and highly dependent upon the tourist industry for the source
of repayment. Because the reliance on tourism is both primary, (i.e. loans to
motels, hotels and restaurants, etc.) and secondary (i.e. loans to employees of
tourist related businesses), it is difficult to assess a specific dollar amount
of inherent loss potential. Likewise, the residential real estate market has
been stable or increasing, so inherent loss potential in this concentration is
also difficult to reasonably assess. Therefore, it is believed that a reasonable
margin should be maintained in the allowance for loan losses to cover this
undefined potential for loss within the loan portfolio.


The following is a summary of nonaccrual, past due and restructured loans as of
December 31:

SUPERVISION AND REGULATION

As a bank holding company within the meaning of the Bank Holding Company Act,
the Company is required by said Act to file annual reports of its operations and
such additional information as the Federal Reserve Board may require and is
subject, along with its subsidiary, to examination by the Federal Reserve Board.
The Federal Reserve Board is the primary regulator of the Company.

The Bank Holding Company Act requires every bank holding company to obtain prior
approval of the Federal Reserve Board before it may merge with or consolidate
into another bank holding company, acquire substantially all the assets of any
bank, or acquire ownership or control of any voting shares of any bank if after
such acquisition it would own or control, directly or indirectly, more than 5%
of the voting shares of such bank holding company or bank. The Bank Holding
Company Act also prohibits a bank holding company, with certain exceptions, from
acquiring direct or indirect ownership or control of more than 5% of the voting
shares of any company which is not a bank and from engaging in any business
other than that of banking, managing and controlling banks or furnishing
services to banks and their subsidiaries. However, holding companies may engage
in, and may own shares of companies engaged in, certain businesses found by the
Federal Reserve Board to be so closely related to banking or the management or
control of banks as to be a proper incident thereto.

Under current regulations of the Federal Reserve Board, a holding company and
its nonbank subsidiaries are permitted, among other activities, to engage,
subject to certain specified limitations, in such banking related business
ventures as consumer finance, equipment leasing, computer service bureau and
software operations, data processing, discount securities brokerage, mortgage
banking and brokerage, sale and leaseback, and other forms of real estate
banking. The Bank Holding Company Act does not place territorial restrictions on
the activities of nonbank subsidiaries of bank holding companies.

In addition, Federal legislation prohibits acquisition of "control" of a bank or
bank holding company without prior notice to certain federal bank regulators.
"Control" in certain cases may include the acquisition of as little as 10% of
the outstanding shares of capital stock.

The Company's cash revenues are derived primarily from dividends paid by the
Bank. National banking laws restrict the payment of cash dividends by a national
bank by providing, subject to certain exceptions, that dividends may be paid
only out of net profits then on hand after deducting therefrom its losses and
bad debts, and no dividends may be paid unless the bank will have a 



                                     Page 6
<PAGE>   8

surplus amounting to not less than one hundred percent (100%) of its common
capital stock.

The Bank is a national banking association and as such is subject to the
regulations of, and supervision and regular examination by, the Office of the
Comptroller of the Currency ("OCC"). Deposit accounts of the Bank are insured by
the Federal Deposit Insurance Corporation ("FDIC"). Requirements and
restrictions under the laws of the State of Michigan and Title 12 of the United
States Code include the requirements that banks maintain reserves against
deposits, restrictions on the nature and amount of loans which may be made by a
bank, and the interest that may be charged thereon, restrictions on the payment
of interest on certain deposits, and restrictions relating to investments and
other activities of a bank. The Federal Reserve Board has established guidelines
for risk based capital by bank holding companies. These guidelines establish a
risk adjusted ratio relating capital to risk-weighted assets and off-balance
sheet exposures. These capital guidelines primarily define the components of
capital, categorize assets into different risk classes, and include certain
off-balance-sheet items in the calculation of capital requirements.


An analysis of the Corporation's regulatory capital requirements at December 31,
1998 is presented on page 21 of the Registrant's 1998 Annual Report which is
incorporated herein by reference.

ITEM 5-MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
      MATTERS.

The common stock of the Company has no public trading market. All trades are
handled on a direct basis between buyer and seller. The Bank acts as the
Company's transfer agent. The principal market for the Company's stock consists
of existing shareholders, family members of existing shareholders and
individuals in its service area.

The information detailing the range of high and low bid information for the
equity for each full quarterly period within the two most recent fiscal years
can be found under the caption "Financial Highlights" of the Company's Annual
Report to Shareholders for the fiscal year ended December 31, 1998, which is
hereby incorporated by reference.

The information which indicates the amount of common equity that is subject to
outstanding options or warrants to purchase, or securities convertible into,
common equity of the registrant can be found in Note 8 on page 16 of the
Company's Annual Report to Shareholders for the fiscal year ended December 31,
1998, which is hereby incorporated by reference.

There are no public offerings pending.

There are approximately 715 shareholders of record of the common stock of the
Company as of March 25, 1999.

During 1998, the Company declared regular dividends of $ 1.34 per share plus a
special dividend of $ .52. In 1997, the Company declared regular dividends of $
1.25 plus a special dividend of $ .46. These per share statistics have been
retroactively adjusted for the 5% stock dividend of June 25,1997, February 20,
1998 and March 1, 1999. Subject to approval of the Board of Directors of the
Company and applicable law, the Company anticipates that it will continue to pay
a regular cash dividend equal to or greater than the prior years. Special
dividends are considered each December based on the current year's earnings.
These have resulted in a dividend payout ratio averaging 65.0% for the past
three years.

The Federal Reserve Board's Policy on the Payment of Cash Dividends by Bank
Holding Companies restricts the payment of cash dividends based on the following
criteria: (1) The Company's net income from operations over the past year must
be sufficient to fully fund the dividend and (2) the prospective rate of
earnings retention must be consistent with the Company's capital needs, asset
quality and overall financial condition.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1998, 1997 and 1996

- --------------------------------------------------------------------------------

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation: The consolidated financial statements include CNB
Corporation (the Company) and its wholly-owned subsidiary, Citizens National
Bank (the Bank). All significant intercompany accounts and transactions are
eliminated in consolidation.

Nature of Operations and Concentrations of Credit Risk: The Company is a
one-bank holding company which conducts no direct business activities. All
business activities are performed by the Bank.

The Bank provides a full range of banking services to individuals, agricultural
businesses, commercial businesses and light industries located in its service
area. It maintains a diversified loan portfolio, including loans to individuals
for home mortgages, automobiles and personal expenditures, and loans to business
enterprises for current operations and expansion. The Bank offers a variety of
deposit accounts, including checking, savings, money market, individual
retirement accounts and certificates of deposit.

The principal markets for the Bank's financial services are the Michigan
communities in which the Bank is located and the area immediately surrounding
these communities. The Bank serves these markets through eight offices located
in Cheboygan, Presque Isle, and Emmet Counties in northern lower Michigan.

Segments: The Company, through its subsidiary, the Bank, provides a broad range
of financial services to individuals and companies in northern Michigan. These
services include demand, time and savings deposits; lending; ATM processing and
cash management. Operations of the Company are managed and financial performance
is evaluated on a company-wide basis. Accordingly, all of the Company's banking
operations are considered by management to be aggregated in one reportable
operating segment.

Use of Estimates: To prepare financial statements in conformity with generally
accepted accounting principles, management makes estimates and assumptions based
on available information. These estimates and assumptions affect the amounts
reported in the financial statements and the disclosures provided, and future
results could differ. The allowance for loan losses, fair values of financial
instruments, and status of contingencies are particularly subject to change in
the near term.

Cash Flow Reporting: Cash and cash equivalents include cash and due from banks
and federal funds sold. Net cash flows are reported for customer loan and
deposit transactions and interest-earning deposits.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1998, 1997 and 1996

- --------------------------------------------------------------------------------


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Securities: Securities classified as held to maturity are carried at amortized
cost when management has the positive intent and ability to hold them to
maturity. Securities are classified as available for sale when they might be
sold before maturity. Securities available for sale are carried at fair value,
with unrealized holding gains and losses reported in shareholders' equity, net
of tax. Trading securities are carried at fair value, with changes in unrealized
holding gains and losses included in income. Realized gains and losses are based
on specific identification of amortized cost. Securities are written down to
fair value when a decline in fair value is not temporary. Interest income
includes amortization of purchase premium or discount.

Other securities, which include Federal Reserve Bank and Federal Home Loan Bank
stocks, are carried at cost.

Loans: Loans are reported at the principal balance outstanding, net of deferred
loan fees and costs and an allowance for loan losses. Loans held for sale are
reported at the lower of cost or market, on an aggregate basis.

Loan Income: Interest income on loans is accrued over the term of the loans
based upon the principal outstanding and includes amortization of net deferred
loan fees and costs over the loan term. Interest income is not reported when
full loan repayment is in doubt, typically when payments are past due over 90
days, unless the loan is both well secured and in the process of collection.
Payments received on such loans are reported as principal reductions.

Allowance for Loan Losses: The allowance for loan losses is a valuation
allowance for probable credit losses, increased by the provision for loan losses
and decreased by charge-offs less recoveries. Management estimates the allowance
balance required based on past loan loss experience, known and inherent risks in
the portfolio, information about specific borrower situations and estimated
collateral values, economic conditions and other factors. Allocations of the
allowance may be made for specific loans, but the entire allowance is available
for any loan that, in management's judgment, should be charged-off.

Loan impairment is reported when full payment under the loan terms is not
expected. Impairment is evaluated in total for smaller-balance loans of similar
nature such as residential mortgage, consumer and credit card loans, and on an
individual loan basis for other loans. If a loan is impaired, a portion of the
allowance is allocated so that the loan is reported, net, at the present value
of estimated future cash flows using the loan's existing rate or at the fair
value of collateral if repayment is expected solely from the collateral. Loans
are evaluated for impairment when payments are delayed, typically 90 days or
more, or when it is probable that all principal and interest amounts will not be
collected according to the original terms of the loan.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Premises and Equipment: Premises and equipment are stated at cost less
accumulated depreciation. Depreciation is computed on the straight-line method
over the assets useful lives. These assets are reviewed for impairment when
events indicate the carrying amount may not be recoverable. Maintenance and
repairs are charged to expense and improvements are capitalized.

Other Real Estate Owned: Real estate properties acquired through, or in lieu of,
loan foreclosure are initially recorded at fair value at acquisition. Any
reduction to fair value from the carrying value of the related loan is accounted
for as a loan loss. After acquisition, a valuation allowance reduces the
reported amount to the lower of the initial amount or fair value less costs to
sell. Expenses, gains and losses on disposition, and changes in the valuation
allowance are reported in other expenses.

Servicing Rights: Servicing rights represent the allocated value of servicing
rights retained on loans sold. Servicing rights are expensed in proportion to,
and over the period of, estimated net servicing revenues. Impairment is
evaluated based on the fair value of the rights, using groupings of the
underlying loans as to interest rates and then, secondarily, as to geographic
and prepayment characteristics. Any impairment of a grouping is reported as a
valuation allowance.

Employee Benefits: A defined benefit pension plan covers substantially all
employees, with benefits based on years of service and compensation prior to
retirement. Contributions to the plan are based on the maximum amount deductible
for income tax purposes. A 401(k) savings and retirement plan has also been
established and covers substantially all employees. Contributions to the 401(k)
plan are made and expensed annually.

Stock Options: No expense for stock options is recorded, as the grant price
equals the market price of the stock at grant date. Pro forma disclosures show
the effect on income and earnings per share had the options' fair value been
recorded using an option pricing model. The pro forma effect is expected to
increase in the future as additional options are granted. Options granted vest
over one year and have a maximum term of ten years. There are 26,041 shares
authorized for future grant.

Income Taxes: Income tax expense is the sum of the current year income tax due
or refundable and the change in deferred tax assets and liabilities. Deferred
tax assets and liabilities are the expected future tax consequences of temporary
differences between the carrying amounts and tax bases of assets and
liabilities, computed using enacted tax rates. A valuation allowance, if needed,
reduces deferred tax assets to the amount expected to be realized.

- --------------------------------------------------------------------------------

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)


Earnings Per Share: Basic earnings per share is based on the net income divided
by the weighted average number of shares outstanding during the period. Diluted
earnings per share shows the dilutive effect of additional potential shares
issuable under stock options.

Stock Splits and Stock Dividends: Dividends issued in stock are reported by
transferring the market value of the stock issued from retained earnings to
common stock and additional paid-in capital. Stock splits are recorded by
adjusting par value. Fractional shares are paid in cash for all stock splits and
dividends. A five percent stock dividend was declared in 1998 and 1997, and a
two-for-one stock split was declared in 1996. On January 28, 1999 the Board of
Directors declared a five percent stock dividend to be paid on March 1, 1999 to
shareholders. Basic earnings per share, diluted earnings per share and dividends
per share have been restated for all stock splits and stock dividends, including
the five percent stock dividend declared January 28, 1999. In 1997 and 1996,
shareholders of the Company approved an increase in the number of authorized
shares from 1,000,000 to 2,000,000 and from 500,000 to 1,000,000, respectively.

Financial Instruments with Off-Balance-Sheet Risk: The Company, in the normal
course of business, makes commitments to extend credit which are not reflected
in the consolidated financial statements. A summary of these commitments is
disclosed in Note 12.

Comprehensive Income: Comprehensive income consists of net income and other
comprehensive income (loss). Other comprehensive income (loss) includes the net
change in net unrealized appreciation (depreciation) on securities available for
sale, net of tax which is also recognized as a separate component of
shareholders' equity. The accounting standard that requires reporting
comprehensive income first applies for 1998, with prior information restated to
be comparable.

Fair Values of Financial Instruments: Fair values of financial instruments are
estimated using relevant market information and other assumptions. Fair value
estimates involve uncertainties and matters of significant judgment regarding
interest rates, credit risk, prepayments, and other factors, especially in the
absence of broad markets for particular items. Changes in assumptions or in
market conditions could significantly affect the estimates. The fair value
estimates of existing on- and off-balance-sheet financial instruments do not
include the value of anticipated future business or the values of assets and
liabilities not considered financial instruments.

Reclassification: Some items in prior financial statements have been
reclassified to conform with the current presentation.

Plan assets are administered by Empire National Bank as trustee of the plan.
Plan assets are invested in diversified mutual funds operated and administered
by the Frank Russell Investment Company.

Deferred Compensation Plan: The Company has a deferred compensation plan to
provide retirement benefits to certain Directors, at their option, in lieu of
annual directors' fees. The present value of future benefits are accrued
annually over the period of active service of each participant. The expense for
the plan was $170,000, $152,000 and $145,000 in 1998, 1997 and 1996,
respectively.

The Company has also purchased insurance on the lives of participating directors
with the Company as the owner and beneficiary of the policies.

In 1997, the Company adopted a deferred compensation plan that allows Executive
officers of the Bank, at Senior Vice President and above, and certain Directors
an opportunity to defer a portion of their compensation. On a monthly basis, the
account of each participant accrues interest based on the interest rate
determined for that year. The expense of the plan was $4,000 and $1,000 in 1998
and 1997, respectively.

401(k) Plan: The Company has a 401(k) savings and retirement plan covering
substantially all employees. Under the plan, employees may defer up to the
lesser of 20% of their eligible compensation or the limitations set by the IRS.
During 1998, 1997 and 1996, the Board of Directors elected to contribute a
matching contribution equal to 100% of the first 2% and 50% of the next 2% of
the employee's deferred compensation. Employee contributions and the Company's
matching percentages are vested immediately. The Company's matching percentages
are determined annually by the Board of Directors and resulted in total
contributions of $58,000, $54,000 and $56,000 in 1998, 1997 and 1996,
respectively.

NOTE 8 - STOCK OPTIONS

Stock Option Plan: The shareholders approved an incentive stock option plan in
May 1996 under which options may be issued at market prices to employees. The
right to exercise the options vests over a one year period. The exercise price
of options granted is equivalent to the market value of underlying stock at the
grant date.

SFAS No. 123 requires proforma disclosures for companies that do not adopt its
fair value accounting method for stock-based employee compensation. Accordingly,
the following proforma information presents net income and earnings per share
had the fair value method been used to measure compensation cost for stock
option plans. Compensation cost actually recognized for stock options was $-0-
for 1998, 1997 and 1996.

The fair value of options granted during 1998 and 1996, is estimated using the
following weighted average information: risk-free interest rate of 5% and 6.5%,
expected life of 10 years, expected dividends of 4.50% and 5.75% per year and
expected stock price volatility of .11. There were no options granted for the
year ended December 31, 1997.

</TABLE>


Related party deposits totaled $862,000 and $1,352,000 at year end 1998 and
1997, respectively.


NOTE 12 - COMMITMENTS, OFF-BALANCE-SHEET RISK, AND CONTINGENCIES

There are various contingent liabilities that are not reflected in the financial
statements, including claims and legal actions arising in the ordinary course of
business. In the opinion of management, after consultation with legal counsel,
the ultimate disposition of these matters is not expected to have a material
effect on financial condition or result of operations.

At year end 1998 and 1997, reserves of $1,009,000 and $1,065,000 were required
as deposits with the Federal Reserve or as cash on hand. These reserves do not
earn interest.

Some financial instruments are used in the normal course of business to meet the
financing needs of customers and to reduce exposure to interest rate changes.
These financial instruments include commitments to extend credit and standby
letters of credit. These involve, to a varying degree, credit and interest-rate
risk in excess of the amount reported in the financial statements.

Exposure to credit loss if the other party does not perform is represented by
the contractual amount for commitments to extend credit and standby letters of
credit. The same credit policies are used for commitments and conditional
obligations as are used for loans.

NOTE 12 - COMMITMENTS, OFF-BALANCE-SHEET RISK, AND CONTINGENCIES
(Continued)

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the commitment.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Since many of the commitments are expected to
expire without being used, the total commitments do not necessarily represent
future cash requirements. Standby letters of credit are conditional commitments
to guarantee a customer's performance to a third party.

A summary of the notional or contractual amounts of financial instruments with
off-balance-sheet risk at year end were as follows:

</TABLE>


Substantially all of these commitments are at variable or uncommitted rates.


NOTE 13 - FAIR VALUES OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate fair values for
financial instruments. The carrying amount is considered to estimate fair value
for cash and variable rate loans or deposits that reprice frequently and fully.
Securities fair values are based on quoted market prices or, if no quotes are
available, on the rate and term of the security and on information about the
issuer. For fixed rate loans or deposits and for variable rate loans or deposits
with infrequent repricing or repricing limits, the fair value is estimated by
discounted cash flow analysis or underlying collateral values, where applicable.
The fair value of off-balance-sheet items approximates cost and is not
considered significant to this presentation.

The estimated year end values of financial instruments were:

NOTE 14 - REGULATORY CAPITAL

The Company and Bank are subject to regulatory capital requirements administered
by federal banking agencies. Capital adequacy guidelines and prompt corrective
action regulations involve quantitative measures of assets, liabilities, and
certain off-balance-sheet items calculated under regulatory accounting
practices. Capital amounts and classifications are also subject to qualitative
judgments by regulators about components, risk weightings and other factors, and
the regulators can lower classifications in certain cases. Failure to meet
various capital requirements can initiate regulatory action that could have a
direct material effect on the financial statements.

The prompt corrective action regulations provide five classifications, including
well capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized and critically undercapitalized, although these terms are not
used to represent overall financial condition. If adequately capitalized,
regulatory approval is required to accept brokered deposits. If
undercapitalized, capital distributions are limited, as is asset growth and
expansion, and plans for capital restoration are required. The minimum
requirements are:

                          INDEPENDENT AUDITOR'S REPORT



Board of Directors and Shareholders
CNB Corporation
Cheboygan, Michigan


We have audited the accompanying consolidated balance sheets of CNB Corporation
as of December 31, 1998 and 1997, and the related consolidated statements of
income and comprehensive income, changes in shareholders' equity and cash flows
for the years ended December 31, 1998, 1997 and 1996. These financial statements
are the responsibility of the Corporation's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free from
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of CNB Corporation as
of December 31, 1998 and 1997, and the results of its operations and its cash
flows for the years ended December 31, 1998, 1997 and 1996, in conformity with
generally accepted accounting principles.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                        December 31, 1998, 1997 and 1996

- --------------------------------------------------------------------------------


This discussion provides information about the consolidated financial condition
and results of operations of CNB Corporation (the Company) and its subsidiary,
Citizens National Bank of Cheboygan (the Bank). This discussion should be read
in conjunction with the financial statements beginning on Page 2 and the related
footnotes.

                               FINANCIAL CONDITION

CASH AND CASH EQUIVALENTS

The Company's balances of cash and cash equivalents remained unchanged from 1998
to 1997. During the year, $2.3 million of cash was provided from financing
activities due to increases in deposits, while $3.5 million of cash was provided
from operating activities. Investing activities utilized $5.8 million of cash
during 1998. The balances maintained in cash and cash equivalents vary based on
daily fluctuations in loan and deposit balances. Sufficient cash is maintained
on a daily basis to meet the anticipated liquidity needs of the Company for
customer transactions and to clear checks drawn on other financial institutions.
The amount of clearings can vary by as much as $3 million in one day, causing
the Company's cash position to vary.

SECURITIES

The Company maintains securities portfolios that include obligations of the U.S.
Treasury and government sponsored agencies as well as securities issued by
states and political subdivisions. Security balances decreased $1.1 million
during 1998. Securities available for sale represent 39.9% of the portfolio.
Currently, the Company primarily maintains a short-term securities portfolio.
The average life of the security portfolio is being extended as securities of a
longer maturity are added to the portfolio when appropriate. As the amount of
securities maturing on a regular basis decreases, liquidity will be maintained
by adding to the available for sale portfolio.

The chart below shows the change in each of the categories of the portfolio.

Holdings in state and municipal securities increased during the year primarily
as a result of increases in funds available through the growth of the deposit
portfolio. The chart below shows the percentage composition of the portfolio as
of December 31.

Securities available for sale are recorded at fair value and securities held to
maturity are recorded at amortized cost. The net unrealized gain on securities
available for sale at December 31, 1998 was $229,000, net of taxes. The
unrealized gains and losses are temporary, since they are a result of market
changes rather than a reflection of credit quality. Management has no specific
intent to sell these securities at the present time.

The Company maintains a conservative security portfolio with a majority of the
investments in U.S. Government and agency securities and issues of governmental
units in our service area. The maturities of the U.S. Government and agency
securities have typically been very short, two years or less, providing
liquidity in addition to quality.

During 1999, management feels that there will be sufficient liquidity to
increase maturity of the investment portfolio, thereby potentially increasing
the yield.

LOANS

Total loans increased $7.2 million or 7.1% during 1998. Substantial growth
occurred in our residential real estate lending which grew to $69.3 million in
1998 from $60.8 million in 1997, or a 14.0% increase. As a full service lender,
the Company offers a variety of personal and commercial loans. Home mortgages
comprise the largest portion of the loan portfolio. The Company generally
retains the ownership of adjustable rate loans and short to medium term
fixed-rate loans and originates and sells long term single family residential
fixed-rate mortgage loans to the secondary market. The Company originated $13.0
million in loans for sale in 1998 and $7.7 million in 1997. This practice allows
the Company to meet the housing credit needs of its service area while
maintaining an appropriate interest rate sensitivity and liquidity position. In
addition to mortgage loans, the Company makes loans for personal and business
use, secured and unsecured, to customers in its services area.

The Company maintains a conservative loan policy and strict credit underwriting
standards. All loans are domestic. An annual review of loan concentrations at
December 31, 1998 indicated the pattern of loans in the portfolio has not
changed. There is no individual industry with more than a 10% concentration,
however, all tourism related businesses, when combined, total 9.8% of total
loans.

ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses represents that amount which management estimates
is adequate to provide for losses inherent in the loan portfolio. Management
determines the adequacy of the allowance for loan losses by reviewing selected
loans (including large loans, non-accrual loans, problem loans and delinquent
loans) and establishes specific loss allowances on these loans. Historical loss
information, local economic conditions and other factors are considered in
establishing allowances on the remaining loan portfolio. The allowance is
increased by provisions charged to expense and reduced by loan losses, net of
recoveries.

The quality of the Company's loan portfolio compares well with its peer group
with non-performing loans at 0.06% of total loans at December 31, 1998 and 0.10%
at December 31, 1997. Loans charged off were 0.05% of total loans during 1998
and 0.04% in 1997. The allowance for loan losses increased in 1998 and 1997 to
an amount considered adequate by management to cover losses that are currently
anticipated based on past experience and specific identification.

CREDIT QUALITY

The Company continues to maintain a high level of asset quality as a result of
actively managing delinquencies, nonperforming assets and potential problem
loans. 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 the 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.

DEPOSITS

The Company's service area has experienced steady economic growth. The Company
offers competitive deposit products and has, therefore, shown steady deposit
growth as it increases its market share. Deposits increased $4.1 million or 2.4%
during 1998. Insured money market deposits increased $4.2 million, non
interest-bearing demand increased $2.3 million and interest-bearing demand
increased $1.0 million. Time deposits decreased $3.7 million from 1997. The
Company held time deposits for a local school building project that was
completed during 1998.

The majority of the Company's deposits are derived from core customers, relating
to long term relationships with local personal, business and public customers.
Deposit rates are monitored continually to assure that the Company pays a
competitive rate.

As of December 31, 1998 the loan to deposit ratio was 63.3% compared to 60.7%
for December 31, 1997. Management continues to emphasize loan growth and would
like to see this ratio at a minimum of 65%. This change in asset mix from
securities to higher yielding loans will increase the net interest margin.

EQUITY

Total equity for the Company at year end 1998 was $19.5 million compared to
$18.1 million in 1997. The Company realized $3.1 million in income and paid out
$2.0 million in dividends during 1998. The unrealized gain on securities
available for sale increased equity an additional $176,000.


                         LIQUIDITY AND FUNDS MANAGEMENT

Effective liquidity management ensures that the cash flow requirements of
depositors and borrowers, as well as the operating cash needs of the Company are
met. The Company's sources of funds have been dividends from the Bank. The
Company manages its liquidity position to provide cash necessary to pay
dividends to shareholders and satisfy other operating requirements.

The Bank manages liquidity to insure adequate funds are available to meet the
cash flow needs of depositors and borrowers. The Banks' most readily available
sources of liquidity are federal funds sold, securities classified as available
for sale and securities classified as held to maturity maturing within one year.
These sources of liquidity are supplemented by new deposits and by loan payments
received from customers. As of December 31, 1998 the Company held $12.7 million
in federal funds sold, $24.2 million in securities available for sale and $25.2
million in held to maturity maturing within one year. These short-term assets
represents 35.6% of total deposits as of December 31, 1998. Historically, the
Company's security portfolio has been short-term in nature, with the average
life of the portfolio consistently being less than two years. The company serves
a market which is highly tied to the tourist industry. Consequently, the Company
experiences seasonal swings in liquidity. Deposit growth occurs during July,
August, and September, then may decline through the fall and winter months.
The Company does not anticipate any significant change in its seasonal pattern.

INTEREST RATE SENSITIVITY

The following schedule details the maturities and yields of interest-bearing
financial instruments at December 31, 1998, for the next five years and
thereafter. The values represent the contractual maturity of each instrument.
For loan instruments without contractual maturities management has allocated
principal payments based upon historical trends of payment activity. Where there
is no set maturity, as in the case of some interest-bearing liabilities,
management has allocated the amounts based upon its expectation of cash flows,
incorporating internal core deposit studies and current expectations of customer
behavior. For loans, securities and liabilities with contractual maturities, the
table presents principal cash flows and related weighted-average interest rates
by contractual maturities. The data in the table was aggregated by type of
financial instrument-fixed and variable rate loans, fixed and variable rate
securities and fixed and variable rate deposits. The Company has no interest
rate swaps, interest rate caps, or interest rate floors. Therefore, data
concerning these instruments is not included in the table.

The primary source of market risk for the financial instruments presented is
interest rate risk. That is, the risk 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 the 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 on shareholders' equity.

                              RESULTS OF OPERATIONS


NET INTEREST INCOME

Interest income is the total amount earned on funds invested in loans,
securities and federal funds sold. Interest expense is the amount of interest
paid on interest-bearing checking, savings and time deposits accounts. Net
interest income is the difference between interest income and interest expense.
The net margin is the net interest income as a percentage of average
interest-earning assets. Interest spread is the difference between the yield on
average interest-earning assets and the cost of average interest-bearing
liabilities. In 1998, net interest income increased $321,000 or 4.2%, due to an
increase in average interest-earning assets of $11.5 million or 6.7%. The
overall yield on average interest-earning assets was 7.85% for 1998 compared to
8.02% for 1997, while the cost on average interest-bearing liabilities was 4.31%
for 1998 compared to 4.35% for 1997. The net interest margin decreased to 4.36%
in 1998 compared to 4.46% in 1997. This decrease can be attributable to a lower
yield on an increasing volume of average interest-earning assets.

In 1997, net interest income increased $382,000 or 5.3%, due to increase in
average interest-earning assets of $9.5 million. The yield on average
interest-earning assets was 8.02% for 1997 compared to 8.01% for 1996 while the
cost of average interest-bearing deposits increased to 4.35% for 1997 from 4.32%
in 1996. The net interest margin (net interest income as a percentage of average
interest-earning assets) decreased to 4.46% from 4.49% due to an increase in the
cost of average interest-bearing liabilities.

on average interest-earning assets (on a pre-tax basis), expense on average
interest-bearing liabilities, and the annualized effective rate or yield for the

NON-INTEREST INCOME

Non-interest income is derived primarily from deposit account fees, fees for
customer services and gains on the sale of residential real estate mortgages to
the secondary market. Non-interest income continues to improve, increasing
$137,000 or 10.5% in 1998. Net realized gains from sales of loans and loan
servicing fees, net of amortization increased $64,000 or 29.5%. Service charge
and fee income increased $59,000 or 7.2% and other income increased $14,000 or
5.2%.

Non-interest income improved in 1997, increasing $263,000 or 25.3%. Service
charge and fee income increased $105,000 or 14.8% and other income increased
$81,000 or 43.3%.

NON-INTEREST EXPENSE

Total non-interest expenses were $4.9 million in 1998 and $4.7 million in 1997.
The Company continued in its efforts to control non-interest expenses during
1998, resulting in total non-interest expenses increasing only 4.3% over 1997
operating expenses. Salaries, wages and employee benefits remain the largest
component of non-interest expense. These expenses totaled $2.9 million in 1998
and $2.7 million in 1997 or a 7.4% increase. Occupancy expense totaled $635,000
in 1998 compared to $620,000 in 1997 while other expenses decreased to $1.1
million in 1998 from $1.2 million in 1997.

Non-interest expense increased $217,000 or 4.9% in 1997. Salary and benefits
increased $142,000 or 5.5%, while net occupancy expense of bank premises
increased $31,000 or 5.3% compared to 1996.

FEDERAL INCOME TAXES

Income tax expense increased 3.0% to $1.3 million in 1998. This was primarily
due to an increase in pre-tax income. The Company's effective tax rate decreased
to 29.4% in 1998 from 30.6% in 1997. There was no significant change in the
Company's income tax position from 1998 to 1997.

The effective tax rates for 1998, 1997 and 1996 are shown in the table below:

</TABLE>


NET INCOME

Consolidated net income was $3.1 million for 1998, compared to $2.9 million for
1997. Return on consolidated average assets for 1998 was 1.61%, compared to
1.58% for 1997. Return on average shareholders' equity was 16.38% in 1998
compared to 16.10% in 1997. Basic earnings per share for 1998, 1997 and 1996
were $2.91, $2.67 and $2.41. Improved net interest income, combined with
improved other income have contributed to this increase.

YEAR 2000 ISSUE

The year 2000 issue poses a threat to businesses everywhere. The problems, which
will evidence themselves in the year 2000, derive from a two-digit limitation in
source programming for calendar years. The Company has assembled an internal
technology committee to thoroughly identify and correct any potential problems
in this area well ahead of the year 2000. Our mission is to continue to offer
continuous quality financial services, which meet the needs of the customers and
communities we serve, into the next millennium. We are committed to allocating
sufficient resources, capital, and personnel to accomplish our mission. We will
identify Y2K risks to the bank and holding company, develop plans and programs
to lower risk to acceptable levels, develop backup plans for failure and adhere
to regulatory requirements.

The Company is currently in Phase 4 of a 5-Phase plan to prepare for the year
2000 issue. In the first phase, the awareness phase, the Company established a
committee to develop a strategy to test our in-house system, service bureaus for
systems that are outsourced, vendors, auditors, customers and suppliers. The
Company also approved a budget for any year 2000 issues. The expense for 1998
was $28,400 and the projected budget for 1999 is $38,775. In addition, the Board
of Directors approved the purchase of a new in-house computer mainframe costing
$321,707 that was purchased and installed in 1998 as well as various surety
agreement options for an additional $111,120. Our regulators have established
several deadlines for financial institutions to comply with the year 2000 issue.
In addition, the Company has reviewed the year 2000 issue with its Board of
Directors, staff and customers.

                        December 31, 1998, 1997 and 1996

- --------------------------------------------------------------------------------

Phase 2 is an assessment phase and general risk control phase during which the
committee assessed the size and complexity of the year 2000 issue. This phase
must identify all hardware, software, networks and automated teller machines,
other various processing platforms, customer and vendor interdependencies
affected by the year 2000 change. The Company's committee identified each item
in terms of business risk it poses and assigned one of our risk categories:
mission critical, mission necessary, mission desirable and mission unrelated.

Phase 3 is a renovation phase, which is changing the lines of computer code to
eliminate the year 2000 problem. This phase includes code enhancements, hardware
and software upgrades, system replacements, vendor certification and other
associated changes. Also the testing of all internal and external applications
was completed by year end 1998.

Phase 4 is the validation phase, which is the phase of testing by institutions
relying on service providers for mission critical systems. The Company is
tentatively scheduled to complete testing on year 2000 by April 15, 1999. This
phase is approximately 95% complete.

Phase 5 is the implementation phase. In this phase, systems should be certified
as year 2000 compliant and be accepted by business users.

The Company has developed a Business Resumption Plan which is designed to
mitigate operational risks should core business processes fail, regardless of
whether mission-critical systems were remediated for the Year 2000. Business
resumption contingency planing is critical because, notwithstanding a financial
institution's successful efforts to thoroughly renovate, validate and implement
Year 2000-ready systems, the potential exists that systems will not operate as
expected.
