                                    PART I
ITEM 1

DESCRIPTION OF BUSINESS
In February 1995, Commercial Bancshares, Inc. (the "Corporation") received
approval from the Board of Governors of the Federal Reserve System to become a
bank holding corporation by acquiring all the voting shares of common stock of
The Commercial Savings Bank (the "Bank"). The principal business of the
Corporation presently is to operate the Bank, which is a wholly owned
subsidiary, and its principal asset. The Corporation and the main office of the
Bank are located at 118 South Sandusky Avenue, Upper Sandusky, Ohio 43351. The
Corporation's telephone number is (419) 294-5781. In May 1997, the Board of
Directors approved the establishment of the Corporation's second wholly owned
subsidiary, a consumer finance company, and thereby chartered a new Ohio
corporation by the name of "Advantage Finance, Inc." On December 24, 1997
approval was granted by the Ohio Division of Financial Institutions for
Advantage Finance, Inc. to do business and the new finance company is expected
to become fully operational providing finance company services to customers in
Marion, Ohio during 1998.

Although wholly owned by the Corporation, the Bank functions as an independent
community bank. The Bank was organized on April 20, 1920 as a state-chartered
Bank and incorporated as "The Lewis Bank & Trust Corporation" under the laws and
statutes of the State of Ohio. An amendment to the articles of incorporation on
February 8, 1929 changed the name of the Bank to The Commercial Savings Bank.
The Bank provides customary retail and commercial banking services to its
customers, including the acceptance of deposits for demand, savings and time
accounts and the servicing of such accounts; commercial, consumer and real
estate lending, including installment loans; Individual Retirement Accounts
(IRA's); safe deposit facilities and night depository facilities. The Bank is a
non-member of the Federal Reserve System, is insured by the Federal Deposit
Insurance Corporation and is regulated by the Ohio Division of Financial
Institutions.

The Bank grants residential, installment and commercial loans to customers
located primarily in Wyandot, Marion, Hardin and Hancock counties and the
surrounding area. Commercial loans are primarily variable rate and include
operating lines of credit and term loans made to small businesses primarily on
the basis of the ability to repay the loan from the cash flow of the business.
Such loans are typically secured by business assets, such as equipment and
inventory, and occasionally by the business owner's personal residence. When the
borrower is not an individual, the Bank generally obtains personal guarantees of
the business owner. Commercial real estate loans are primarily secured by
borrower-occupied business real estate, and are also dependent on the ability of
the related business to generate adequate cash flow to service the debt. Such
loans primarily carry adjustable interest rates. Residential real estate loans
are primarily fixed rates secured by the borrower's residence. Such loans are
made on the basis of the borrower's ability to make repayment from employment
and other income. The Bank generally makes these loans in amounts of 95% or less
of the value of the collateral. An appraisal is obtained from a qualified real
estate appraiser for substantially all loans secured by real estate.
Construction loans are secured by residential and business real estate that
primarily will be borrower-occupied upon completion. The Bank usually makes the
permanent loan at the end of the construction phase. Installment loans to
individuals include loans secured by automobiles and other consumer assets,
including second mortgages on personal residences. Loans secured by automobiles
are generated both by direct application from the customer and from the Bank's
purchase of indirect retail installment contracts from the dealers. Credit card
and overdraft protection loans are unsecured personal lines of credit to
individuals.

The Corporation is not aware of any exposure to material costs associated with
environmental hazardous waste cleanup. Bank loan procedures require EPA studies
be obtained by Bank management prior to approving any commercial real estate
loan with such potential risk.

SUPERVISION AND REGULATION
REGULATION OF THE CORPORATION: The Corporation is a registered bank holding
company organized under the laws of the State of Ohio on March 22, 1994. As
such, the Corporation is subject to the laws of the State of Ohio and is under
the jurisdiction of the Securities Act of 1933, as amended, and various
Securities and Exchange Commission rules and regulations relating to the
offering and sale of its securities. Commercial Bancshares, Inc. is also subject
to regulation under the Bank Holding Company Act of 1956, as amended. The
Federal Reserve Board regulates bank holding companies and may examine or
inspect the books and records of the Corporation and the Bank.

Commercial Bancshares, Inc. is not aware of any current recommendations by
regulatory authorities that, if they were to be implemented, would have a
material effect on the Corporation.

REGULATION OF THE BANK: The Bank is chartered in the State of Ohio and regulated
by the Ohio Division of Financial Institutions. Further, the Bank's depositors
are insured by the Federal Deposit Insurance Corporation. These regulatory
agencies have the authority to examine the books and records of the Bank, and
the Bank is subject to their rules and regulations.

EMPLOYEES
Currently the Bank has 87 full-time employees and 13 part-time employees. The
Corporation does not have any full- or part-time employees.

The Bank also operates an intermittent office inside the Rotary Towers Nursing
Facility in Marion opened in June 1991. The Corporation neither owns or leases
any properties. During 1997, the Corporation closed an intermittent office
inside the Marion Steel Corporation in Marion and sold a full service banking
office in Kenton.

ITEM 3
LEGAL PROCEEDINGS
Corporation management is aware of no pending or threatened litigation in which
the Corporation or its subsidiary Bank faces potential loss or exposure which
will materially affect the consolidated financial statements or involves a claim
for damages exceeding 10% of the current assets of the Bank.

ITEM 5
MARKET FOR COMMON EQUITY AND
RELATED SHAREHOLDER MATTERS
The common stock of the Corporation, and of the Bank preceding formation of the
Corporation, trades infrequently and is not traded on any established securities
market. Parties interested in buying or selling the Corporation's stock are
generally referred to Community Banc Investments, New Concord, Ohio (CBI) or
Sweney Cartwright & Co., Columbus, Ohio (Sweney) who took an active position in
the Corporation's stock during the fourth quarter of 1996.

For 1997, bid and ask quotations were obtained and compared from CBI and Sweney;
and for 1996, bid and ask quotations were obtained from CBI which make a limited
market in the Corporation's stock. The quotations are inter-dealer prices,
without retail markup, markdown, or commission and may not represent actual
transactions.

Management does not have knowledge of the prices paid in all transactions and
has not verified the accuracy of those prices that have been reported. Because
of the lack of an established market for the Corporation's stock, these prices
may not reflect the prices at which the stock would trade in an active market.

On May 14, 1997 the Board of Directors of Commercial Bancshares, Inc. approved a
3-for-1 stock split, effected as a dividend, payable on June 30, 1997 to
shareholders of record on June 15, 1997, issuable from the Corporation's
authorized shares.

The Corporation has 1,041,456 authorized and outstanding shares of common stock
held by approximately 1,300 shareholders as of December 31, 1997. The
Corporation has paid cash dividends in June and December of each year, resulting
in a total amount of $0.70 per share for 1997 and $0.6666 per share for 1996,
restated for the stock split.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATION

RESULTS OF OPERATION
Net income in 1997 of $1,839,057 represents a 33.2% increase from the net income
of $1,380,781 in 1996. Diluted earnings per share increased proportionately from
$1.33 in 1996 to $1.76 in 1997. The major factors that have influenced these
results are discussed below.

NET INTEREST INCOME
Net interest income, the primary source of earnings for the Corporation, is the
amount by which interest and fees on loans and investments exceed the interest
cost of deposits and other borrowings to fund them. Changes in mix and volume of
earning assets and interest bearing liabilities and their related yields and
interest rates have a major impact on earnings. Management attempts to manage
the repricing of assets and liabilities to achieve a stable level of net
interest income and minimize the effect of significant changes in the market
level of interest rates. Management is active in pricing and promotion of loan
and deposit products as well as closely monitoring Corporate investment
securities classified as available for sale.

The interest rate sensitivity gap (GAP) table below indicates that, as of
December 31, 1997, rate sensitive liabilities exceed rate sensitive assets in
the one year or less time horizon by approximately $3,368,000. Management
believes this places the Corporation in a desirable position for 1998 as rates
are projected to remain relatively flat and possibly decline slightly. With this
in mind, management desires liabilities to reprice faster than rate sensitive
assets in this rate environment. For purposes of the GAP table, management has
excluded passbook savings and NOW checking accounts from the one year period.
These deposits were not historically considered rate sensitive, however, with
the dramatic decrease in rates in 1992 and 1993 management did adjust the rates
paid on these accounts and began to include these deposits in the one year time
window which had a significant impact on the GAP position. If rates rise in the
future these deposit products will rise but only to historical levels which have
been among the most inexpensive products offered by the Bank. In addition, these
deposit products are not tied to an external index which give management
flexibility in timing future rate increases to these products.

NET INTEREST INCOME (Continued)
While the volume of both earning assets and interest bearing liabilities
increased in 1997, differences in rates and deposit mix served to somewhat
offset the impact to net interest income. The average yield on earning assets
declined from 8.43% in 1996 to 8.33% in 1997. The major factors were a decrease
in the yield on loans and tax exempt securities. Management continued its
emphasis on commercial loans which is reflected in the growth in this portfolio
of approximately $9,656,000. To remain competitive, loans were priced very
aggressively and an overall decline in loan pricing was seen in 1997. In
addition, a decrease did occur in the installment loan portfolio in 1997 in the
amount of $3,194,000. The decrease was primarily in the indirect loan portfolio
due to runoff and larger than expected charge-offs. Management has reduced
funding for these loans and centralized the underwriting process. Management
does not anticipate the increased level of charge-offs experienced to continue.
The Bank has strategically targeted managed growth in the commercial and home
equity loan areas for 1998. The yield decline in earning assets was exacerbated
by an increase in the yield on interest bearing liabilities, from 4.52% in 1996
to 4.71% in 1997. The increase in the yield on interest bearing liabilities is
due to the higher rate the Bank must pay on time deposits as it competes with
non-deposit alternatives such as mutual funds and stocks. Management has
alternative lower cost sources of funds such as Federal Home Loan Bank advances
and federal funds purchased to utilize if needed.

Management continues to closely monitor net interest income, while maintaining
competitive loan and deposit rates in the markets we serve. Although no one can
accurately predict future movement in interest rates, management expects a
continued stable to slightly lower rate environment for 1998.

The following tables further illustrate the impact on net interest income of
changes in average balances and yields of the Corporation's assets and
liabilities.

For purposes of these tables, the changes in interest due to both volume and
rate have been allocated to volume and rate changes in proportion to the
relationship of the absolute dollar amounts of the changes in each. 

(1)  Tax exempt income is adjusted to a fully tax equivalent basis utilizing a
     34% tax rate.
(2)  Non-accrual loan balances are included for purposes of computing the rate
     and volume effects although interest on these balances has been excluded.

ALLOWANCE AND PROVISION FOR POSSIBLE LOAN LOSS

The allowance for possible loan losses on December 31, 1997 was .85% or
$1,075,384 of total loans. This compares to .88% or $1,018,608 of total loans in
1996. The Corporation's policy is to charge-off loans when, in management's
opinion, collection is in doubt. All loans charged-off are subject to continuing
review and concerted efforts are made to maximize recovery.

The Corporation provided $613,000 to the allowance for loan losses in 1997, to
maintain the provision at an adequate level following charge-offs of $642,813
and recoveries of $86,589 and to adjust for the larger than expected charge-offs
of indirect loans discussed earlier.

The schedule to the right presents analysis of the allowance for loan losses,
average loan data and related ratios for the years ended December 31, 1997 and
1996.

The allowance for possible loan losses is maintained by management at a level
considered adequate to cover possible losses that are currently anticipated
based on past loss experience, general economic conditions, information about a
specific borrower including their financial position and collateral values, and
other factors and estimates which are subject to change over time. To maintain
an adequate allowance, management also considers the historical trend of
delinquencies and nonperforming loans as well as changes in the composition and
mix of the loan portfolio. The provision for loan losses charged to expense in
1998 is expected to be at least 1% of gross loan growth of the loan portfolio.

</TABLE>

Nonaccrual loans totaled $1,073,000 at December 31, 1997 as compared to $237,000
at December 31, 1996. The increase is primarily due to commercial loan
relationships. Nonaccrual loans are adequately reserved for, if necessary, and
no additional loss is expected. The policy for placing loans on nonaccrual
status is to cease accruing interest on loans when management believes that the
collection of interest is doubtful, or when loans are past due as to principal
and interest ninety days or more, except that in certain circumstances interest
accruals are continued on loans deemed by management to be fully collectible. In
such cases, the loans are individually evaluated in order to determine whether
to continue income recognition after ninety days beyond the due dates. When
loans are charged-off, any accrued interest recorded in the fiscal year is
charged against interest income. The remaining balance is treated as a loan
charged-off.

The Corporation considers loans impaired if full principal and interest payments
are not anticipated. Impaired loans are carried at the present value of expected
cash flows discounted at the loan's effective interest rate or at the fair value
of the collateral if the loan is collateral dependent. A portion of the
allowance for loan losses is allocated to impaired loans.

Commercial loans and commercial real estate loans that are classified as
substandard or doubtful through the internal loan review process, and loans that
have been placed on nonaccrual status are evaluated for impairment on a
loan-by-loan basis. Smaller balance homogeneous loans are evaluated for
impairment in total. Such loans included residential first mortgage loans, home
equity, automobile and credit card loans.


The following schedule summarizes impaired loans as of December 31, 1996 and
December 31, 1996.

No interest income recognized on impaired loans in 1997 and 1996.

Another factor associated with asset quality is Other Real Estate Owned
("OREO"). OREO represents properties acquired by the Corporation through loan
defaults by customers. At December 31, 1997, the balance in OREO stood at
$1,065,000, representing the acceptance of a deed in lieu of foreclosure in late
1994. Other real estate is carried at the lower of cost or estimated fair market
value less estimated expenses to be incurred to sell the property.

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

NONINTEREST INCOME

Total noninterest income of $2,006,696 was 79.6% higher than the 1996 figure
of $1,117,620. This increase occurred due to the gain on the sale of the
property, equipment and deposits of the Kenton branch in December 1997. An
additional contributor to noninterest income was an $81,470 increase in net
gains on sale of securities.

NONINTEREST EXPENSE
Total noninterest expense decreased $8,661 in 1997. Customary merit increases to
employees; increases in occupancy, furniture and equipment; and increases in
data processing were offset by the decrease in FDIC deposit insurance premiums
due to the one-time assessment of $154,011 in 1996.

INCOME TAXES
Income tax expense of $605,024 in 1997 represents 24.8% of income before taxes
as compared to 21% in 1996. These effective tax rates are both lower than
the statutory rate of 34%, primarily as a result of the Bank's investment in
tax-exempt obligations from states and political subdivisions. Tax exempt income
from securities represented 5.4% and 5.9% of total interest income in 1997 and
1996.

FINANCIAL CONDITION
TOTAL ASSETS
Total assets increased slightly to $181,366,767 from $180,960,972. Net loans
increased 8.5% or $9,748,357 while securities decreased 25.1% or $12,850,829.
Cash and cash equivalents increased 12.9% from 1996.

The Corporation has received approval from the appropriate regulatory agency to
form a finance company, Advantage Finance, Inc. (Advantage), in Marion, Ohio.
The purpose of Advantage is to provide financing for higher risk borrowers that
do not meet the more stringent underwriting criteria of the Bank. Operations are
expected to begin in the first quarter of 1998.

LOANS
Consumer and credit card loans decreased 8.6% or $3,194,451 from 1996 levels.
The Corporation was active in the indirect loan business, which accounted for
substantial consumer loan growth in 1996. In 1997, management responded
to larger than expected charge-offs of the indirect loan portfolio by reducing
funding, revising the underwriting criteria to better represent the additional
inherent risk in these types of credits and centralized the underwriting
procedures. Commercial loans showed an increase of 18.9% in 1997. This is a
result of management's commitment to the business client. A new division was
formed, the Corporation's Business Development Team, made up of qualified
commercial lenders whose area of expertise has been expanded to provide for a
total banking relationship for the Corporation's business clients.

Real estate loans showed an increase of 9.2% or $2,102,751, which primarily
represents loans originated for sale in the secondary market. These loans are
carried at the lower of cost or fair value and were approximately $5,191,000 and
$2,586,000 at December 31, 1997 and 1996. With the demand for mortgage loans
continuing to be in the fixed rate area, the Corporation will continue to sell
fixed rate mortgage loans to the Federal Home Loan Mortgage Corporation (FHLMC)
as the Bank is an authorized seller/servicer for the FHLMC. Management
anticipates the amount of fixed rate loans sold to FHLMC with servicing retained
by the Bank to continue with the low-interest-rate environment. Loans sold to
the FHLMC for which the Bank retains servicing rights totaled $23,411,756 as of
December 31, 1997, compared to $17,144,184 as of December 31, 1996. At December
31, 1997, other assets include a receivable of approximately $3,508,000 for
loans sold.

The Bank's loan portfolio represents its largest and highest yielding earning
assets. It also contains the most risk of loss. This risk is due primarily to 
changes in borrowers' primary repayment capacity, and to collateral values that 
are subject to change over time. These risks are managed with specific 
underwriting guidelines, loan review procedures and training of personnel.

The following is a schedule of maturities of fixed rate loans based on contract
terms, excluding real estate mortgage and installment loans, rounded to the
nearest thousand, as of December 31, 1997.

INVESTMENT AND MORTGAGE-BACKED SECURITIES

Mortgage-backed securities decreased 22.2% or $5,316,514
in 1997; obligations of federal agencies decreased 36.6% or $4,031,870; and
obligations of state and political subdivisions decreased 24.3% or $3,557,890 in
1997. Securities were sold to fund the Bank's increased loan demand and to fund
the liability assumption from the sale of the Kenton branch in December 1997.

As of December 31, 1996, there are no concentrations of securities of any one
issuer, other than U.S. Government and Government Agencies, whose carrying value
exceeds 10% of shareholders' equity.

The weighted average interest rates are based on coupon rates for investment and
mortgage-backed securities purchased at par value and on effective interest
rates considering amortization or accretion if the investment and
mortgage-backed securities were purchased at a premium or discount. The weighted
average yield on tax exempt obligations has not been determined on a tax
equivalent basis. Equity securities consist of Federal Reserve Bank stock that
bears no stated maturity or yield and is not included in this analysis.
Maturities are reported based on stated maturities and do not reflect principal
prepayment assumptions. Available-for-sale yields are based on amortized cost
balances.

DEPOSITS

Total deposits decreased 2.5% or $4,090,800, net. The net decrease was
experienced due to the sale of the deposits at the Kenton branch approximating
$9,899,000. The gross increase in deposits was 3.5% or $5,808,405. Attractive
rates were offered throughout 1997 due to market forces and the need to fund the
loan demand.

The following is a schedule of maturities of time certificates of deposit in
amounts of $100,000 or more as of December 31, 1997:

CAPITAL RESOURCES
Total shareholders' equity at December 31, 1997 was $15,688,343 an increase
of 9.6% or $1,375,098 from total shareholders equity of $14,313,245 at December
31, 1996. The increase is modest in nature due to the Corporation's dividend
payout which amounted to $729,019 for the year ended December 31, 1997 and
higher market value of the Bank's investment portfolio available for sale which
shows an unrealized loss of $226,210, (net of tax), at December 31, 1997
compared to an unrealized loss of $491,270 (net of tax) at December 31, 1996.

Banking regulations have established minimum capital requirements for banks
including risk-based capital ratios and leverage ratios. As of December 31,
1997, risk-based capital regulations require all banks to have a minimum total
risk-based capital ratio of 8%, with half of the capital composed of core
capital. Minimum leverage ratios range from 3% to 5% of total assets.
Conceptually, risk-based capital requirements assess the riskiness of a
financial institution's balance sheet and off-balance sheet commitments in
relation to its capital. Core capital, or Tier 1 capital, includes common
equity, perpetual preferred stock and minority interests that are held by others
in consolidated subsidiaries minus intangible assets. Supplementary capital, or
Tier 2 capital, includes core capital and such items as mandatory convertible
securities, subordinated debt and the allowance for loans and lease losses,
subject to certain limitations. Qualified Tier 2 capital can equal up to 100% of
an institution's Tier 1 capital with certain limitations in meeting the total
risk-based capital requirements.

At December 31, 1997, the Bank's total risk-based capital ratio and leverage
ratio was 13.2% and 8.4%, thus exceeding the minimum regulatory requirements.
At December 31, 1996, the ratios were 10.2% and 8.6%.

The Corporation's Board of Directors declared a $0.35 per share cash dividend in
both May and November of 1997, paying a total of $729,019. In addition,
the previously mentioned 3-for-1 stock split resulted in the issuance of 694,304
additional shares of common stock, bringing the total shares outstanding to
1,041,456. The Corporation's 1997 return on average shareholder equity was
12.49% compared to 9.83% in 1996. The increase is attributed to the sale of the
Kenton branch in 1997. Total cash dividends paid in 1997 represented 39.64% of
total 1997 net income. This compares to a dividend payout ratio of 50.28% in
1996.

LIQUIDITY
Liquidity management for the Bank centers around the assurance funds are
available to meet the loan and deposit needs of its customers and the Bank's
other financial commitments.

Cash and noninterest bearing deposits with banks, federal funds sold and other
short-term investments totaled $7,111,986 at December 31, 1997 and $6,299,450 at
December 31, 1996. These assets provide the primary source of liquidity for the
Bank. In addition, the Bank has designated a substantial portion of its
investment portfolio as available for sale to provide an additional source of
liquidity.

A measure of liquidity is the relationship of loans to deposits and borrowed
funds. Lower ratios indicate greater liquidity. At December 31, 1997 and 1996,
the ratio of loans (net of unearned income) to deposits and borrowed funds was
76.42% and 70.02%, respectively, considered an acceptable level of liquidity by
management.

IMPACT OF INFLATION
The financial data included herein has been prepared in accordance with
generally accepted accounting principals (GAAP), which generally does not
recognize changes in the relative value of money due to inflation or recession.

In management's opinion, changes in interest rates affect the financial
condition of a financial institution to a far greater degree than changes in the
inflation rate. While interest rates are greatly influenced by changes in the
inflation rate, they do not change at the same rate or in the same magnitude as
the inflation rate. Rather, interest rate volatility is based on changes in
monetary and fiscal policy. A financial institution's ability to be relatively
unaffected by changes in interest rates is a good indicator of its capability to
perform in today's volatile economic environment. The Bank seeks to insulate
itself from interest rate volatility by ensuring that rate sensitive assets and
rate sensitive liabilities respond to changes in interest rates in a similar
period and to a similar degree.

(Advantage). All significant intercompany balances and transactions have been
eliminated in consolidation.

INDUSTRY SEGMENT INFORMATION: Commercial Bancshares, Inc. is a bank holding
Corporation engaged in the business of commercial and retail banking, with
operations conducted through its main office and branches located in Upper
Sandusky, Ohio and neighboring communities. This market area provides the source
of substantially all of the Corporation's deposit and loan activities. The
majority of the Corporation's income is derived from commercial and retail
business lending activities and investments.

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 collectibility of loans, fair values of financial
instruments, and status of contingencies are particularly subject to change.

CASH AND CASH EQUIVALENTS: Cash and cash equivalents include cash, noninterest
bearing demand deposits with banks and federal funds sold. Net cash flows are
reported for customer loan and deposit transactions. During 1997 and 1996, the
Corporation paid $7,370,171 and $6,316,545 in interest and $445,000 and $191,000
for income taxes.

SECURITIES: Securities are classified as held to maturity and 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 separately in shareholders'
equity, net of tax. Securities are classified as trading when held for
short-term periods in anticipation of market gains, and are carried at fair
value. Securities are written down to fair value when a decline in fair value is
not temporary. At year end 1997 and 1996, no securities were classified as
trading.

Realized gains and losses on sales are determined using the amortized cost of
the specific security sold. Interest income includes amortization of purchase
premiums and discounts.

LOANS HELD FOR SALE: Certain residential mortgage loans are originated for sale
in the secondary mortgage loan market. These loans are included in the real
estate loans and are carried at the lower of cost or estimated fair value taken
together. Net unrealized losses are recognized through a valuation allowance by
charges to income. To mitigate the interest rate risk, fixed commitments may be
obtained at the time loans are originated or identified for sale.

LOANS RECEIVABLE: Loans are reported at the principal balance outstanding, net
of deferred loan fees and costs, allowance for loan losses, and charge-offs.
Interest income is reported on the interest method 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. Payments received on such loans are
reported as principal reductions.

ALLOWANCE FOR LOAN LOSSES: The allowance for loan losses is a valuation
allowance, 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.

A loan is considered impaired when management believes full collection of
principal and interest is not probable. Often this is associated with a
significant delay or shortfall in payments. Smaller-balance homogeneous loans
are evaluated for impairment in total. Such loans include residential first
mortgage loans secured by one-to-four family residences and consumer automobile,
home equity and credit card loans with balances less than $200,000. In addition,
loans held for sale are excluded from consideration of impairment.

The Corporation reduces the carrying value of impaired loans to the present
value of expected future cash flows, or to the fair value of collateral if the
loan is collateral dependent, by allocating a portion of the allowance for loan
losses to such loans. If these allocations should require an increase, such
increase is reported as bad debt expense.

The carrying values of impaired loans are periodically adjusted to reflect cash
payments, revised estimates of future cash flows and increases in the present
value of expected cash flows due to the passage of time. Cash payments
representing interest income are reported as such. Other cash payments are
reported as reductions in carrying value, while increases or decreases due to
changes in future payments and due to the passage of time are reported as part
of the provision for loan losses.

CONCENTRATIONS OF CREDIT RISK: The Corporation, through its subsidiary Bank,
grants commercial, real estate, consumer and home equity loans to customers
mainly in Wyandot, Marion, Hardin and Hancock Counties of Ohio. Commercial loans
include loans secured by business assets and agricultural loans secured by crops
and equipment. Commercial loans make up approximately 48% and 44% of the loan
portfolio at year end 1997 and 1996 and the loans are expected to be repaid from
cash flow from operations of the borrower. Real estate mortgages make up
approximately 25% and 24% of the loan portfolio at year end 1997 and 1996 and
are secured primarily by first and second mortgages on residential real estate,
business real estate and agricultural real estate. Loans related to the
agricultural industry represented 9% and 10% of total loans at year end 1997 and
1996. Consumer loans include new and used automobile and other consumer purpose
loans. Consumer loans make up approximately 27% and 32% of total loans at year
end 1997 and 1996. The Bank also originates consumer-oriented purchase-money
loans indirectly through various automobile, motorcycle, boat,

recreational vehicle and other dealerships. Indirect loans represented 92% and
75% of consumer loans and 24% of total loans at year end 1997 and 1996.
Unsecured loans represented 2% of total loans at year end 1997 and 1996.

At year end 1997 and 1996, the Bank had due from bank balances and overnight
federal funds sold to National City Bank totaling $4,680,000 and $4,466,000,
respectively.

PREMISES AND EQUIPMENT: Asset cost is reported net of accumulated depreciation.
Depreciation expense is calculated using the straight-line method based on the
estimated useful lives of the assets. These assets are reviewed for impairment
when events indicate the carrying amount may not be recoverable.

OTHER REAL ESTATE: Real estate acquired in settlement of loans is initially
reported at estimated fair value at acquisition. After acquisition, a valuation
allowance reduces the reported amount to the lower of the initial amount or fair
value less costs to sell. Expenses incurred are charged to operations as
incurred. Gains and losses on disposition, and changes in the valuation
allowance are reported in net gain or loss on other real estate.

GOODWILL AND IDENTIFIED INTANGIBLES: Goodwill is the excess of purchase price
over identified net assets in business acquisitions. Goodwill is expensed on the
straight-line method over a period of 15 years. Identified intangibles represent
the value of depositor relationships purchased and is expensed on an accelerated
method over a period of 15 years. Goodwill and identified intangibles are
assessed for impairment based on estimated undiscounted cash flows, and written
down if necessary.

Goodwill and identified intangibles are included in other assets and are
summarized as follows at year end 1997 and 1996, net of accumulated
amortization:

                                  1997              1996

   Core deposit intangible     $     80,065      $    197,011
   Goodwill                          79,416           172,622
                               ------------      ------------
    TOTAL INTANGIBLE ASSETS    $    159,481      $    369,633
                               ============      ============
                              
Amortization expenses totaled $54,680 in 1997 and $46,224 in 1996. Core deposit
intangible and goodwill related to the Kenton branch were considered in the
basis of the net liabilities sold as part of the sale of this branch.

LOAN SERVICING: The Company has sold various loans to the Federal Home Loan
Mortgage Corporation (FHLMC) while retaining the servicing rights. Gains and
losses on loan sales are recorded at the time of the sale.

SFAS No. 122, "Accounting for Mortgage Servicing Rights," was adopted on January
1, 1996. It requires entities to recognize, as separate assets, rights to
service mortgage loans for others, regardless of how these rights are acquired.
Mortgage servicing rights acquired through either the purchase or the
origination of mortgage loans which are subsequently sold with servicing rights
retained are determined by allocating the total cost of the mortgage loans to
mortgage servicing rights and to loans (without the mortgage servicing rights)
based on their relative fair values. Mortgage servicing rights recorded as a
separate asset are amortized in proportion to, and over the period of, estimated
net servicing income. 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. This pronouncement was
superseded by SFAS No. 125, "Accounting for Transfers and Servicing of Financial
Assets and Extinguishments of Liabilities," which extends the accounting and
disclosure rules for mortgage servicing rights to all servicing rights including
mortgage, consumer and commercial loans. Mortgage servicing rights totaled
$193,417 at year end 1997 and $102,473 at year end 1996, and are included in
"Other assets," on the accompanying balance sheet.

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.

FAIR VALUES OF FINANCIAL INSTRUMENTS: Fair values of financial instruments
are estimated using relevant market information and other assumptions, as more
fully disclosed separately. 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 does not include the value of
anticipated future business or the values of assets and liabilities not
considered financial instruments.

EARNINGS PER SHARE: Basic and diluted earnings per share are computed under
a new accounting standard effective in the quarter ended December 31, 1997. All
prior amounts have been restated to be comparable. Basic earnings per share is
based on net income divided by 1,041,456 weighted average shares outstanding
during the years ended December 31, 1997 and 1996. Diluted earnings per share
reflects the effect of additional common shares issuable under stock options 
using the treasury stock method. The weighted average number of shares used for
determining diluted earnings per share were 1,043,391 in 1997. There were no
stock options issuable in 1996. Diluted earnings per share was lower than basic
earnings per share by $0.01 in 1997. There was no difference between basic and
diluted earnings per share in 1996.

In May 1997, the Board of Directors declared a 3-for-1 stock split, resulting in
the issuance of 694,304 shares. In March 1996, the Board of Directors declared a
25% stock split effected in the form of a dividend, resulting in the issuance of
69,063 shares. The weighted average number of shares outstanding and the per
share data for prior periods has been restated to retroactively reflect this
stock split.

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

NOTE 9 - STOCK  OPTION PLAN

The Commercial Bancshares, Inc. Incentive Stock Option Plan was approved by
shareholders in April 1997. The plan enables a committee of the Board of
Directors to grant stock options to executive officers of the Corporation and
its subsidiaries. A total of 150,000 options on common shares are available to
be granted pursuant to the plan, after giving effect to the stock split
discussed in Note 1. Stock options may be granted at a price not less than the
fair market value of the Corporation's common shares at the date of grant for
terms up to, but not exceeding ten years from the grant date. Vesting occurs
after five years. Exceptions to the vesting schedule can operate to shorten the
vesting time. In October 1995, the Financial Accounting Standards Board issued
SFAS No. 123, "Accounting for Stock-based Compensation," which encourages the
use of a fair value-based method to account for stock-based compensation plans
such as the Corporation's stock option plan. As allowed by SFAS No. 123,
however, the Corporation has elected to continue to follow prior standards in
accounting for its stock options. Under these standards, because the exercise
price of the Corporation's stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

If compensation expense is not recorded, pro forma information regarding net
income and earnings per share is required by SFAS No. 123, and has been
determined as if the Corporation had accounted for its stock options under the
fair value method of that Statement. The fair value for these options was
estimated at the date of grant using an option pricing model with the following
assumptions for 1997: risk-free interest rate of 6.42%; dividend yield of 3.50%;
volatility factor of the expected market price of the Corporation's common stock
of 16.05%; and a weighted average expected life of the options of ten years.
There were no stock options granted or outstanding in 1996. For purposes of pro
forma disclosures, the estimated fair value of the options is amortized to
expense over the options' five-year vesting period.
The Corporation's pro forma information follows:

During 1997, the Corporation met one of the exceptions to the vesting schedule
resulting in 15,000 options from the initial grant of 30,000 options becoming
exercisable.

NOTE 10 - SALARY DEFERRAL - 401(k) PLAN
The Corporation maintains a 401(k) plan covering substantially all employees who
have attained the age of 21 and have completed one year of service with the
Corporation. This is a salary deferral plan, which calls for matching
contributions by the Corporation based on a percentage (50%) of each
participant's voluntary contribution (limited to a maximum of six percent (6%)
of a covered employee's annual compensation). In addition to the Corporation's
required matching contribution, a contribution to the plan may be made at the
discretion of the Board of Directors. The Corporation's matching and
discretionary contributions were $66,646 and $68,718 for the years ended
December 31, 1997 and 1996.

NOTE 11 - 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 results of operations.

Some financial instruments are used in the normal course of business to meet the
financing needs of customers. These financial instruments include commitments to
extend credit and standby letters of credit which involve, to varying degrees,
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. Each customer's credit worthiness is evaluated on a case-by-case basis.
The same credit policies are used for commitments and conditional obligations as
are used for loans. The amount of collateral obtained, if deemed necessary, upon
extension of credit is based on management's credit evaluation. Collateral
varies but may include accounts receivable, inventory, property, equipment,
income-producing commercial properties, residential real estate and consumer
assets.

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.

At year end 1997 and 1996, reserves of $718,000 and $708,000 were required as
deposits with the Federal Reserve or as cash on hand. These reserves do not earn
interest.


NOTE 12 - REGULATORY MATTERS
The Corporation 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 under-capitalized, although these terms are not
used to represent overall financial condition. If adequately capitalized,
regulatory approval is required to accept brokered deposits. If
under-capitalized, capital distributions are limited, as is asset growth and
expansion, and plans for capital restoration are required. The minimum
requirements are:

Dividends paid by the Bank are the primary source of funds available to the
Corporation for payment of dividends to shareholders and for other working
capital needs. The payment of dividends by the Bank to the Corporation is
subject to restrictions by regulatory authorities. These restrictions generally
limit dividends by the Bank to the current and prior two year's retained
earnings as defined by regulations. At year end 1997, approximately $3,203,000
of the Bank's retained earnings were available for dividends to the Corporation
under these guidelines. In addition to these restrictions, as a practical
matter, dividend payments cannot reduce regulatory capital levels below the
Corporation's regulatory capital requirements and minimum regulatory guidelines.
These restrictions do not presently limit the Corporation from paying normal
dividends.

</TABLE>

The following assumptions were used for purposes of the previous disclosures of
estimated fair value. The carrying amount is considered to estimate fair value
for cash and cash equivalents, for cash surrender value of life insurance, for
mortgage servicing rights, for loans that contractually reprice at intervals of
less than twelve months, for demand and savings deposits, borrowed funds and for
accrued interest. Securities fair values are based on quoted market prices for
the individual securities or for equivalent securities. The fair values of
fixed-rate loans, loans that reprice less frequently than each six months, and
time deposits are estimated using a discounted cash flow analysis using year end
market interest rates for the estimated life and credit risk. The estimated fair
value of commitments is not material.

While these estimates of fair value are based on management's judgment of the
most appropriate factors, no assurance can be given that, were the Bank to have
disposed of such items at year end 1997 or 1996, the estimated fair values would
necessarily have been achieved at these dates, since market values may differ
depending on various circumstances. The estimated fair values at year end 1997
and 1996 should not necessarily be considered to apply at subsequent dates.

Nonfinancial instruments may have value but are not included in the above
disclosures, such as property and equipment. In addition, nonfinancial
instruments typically not recognized in these financial statements nevertheless
may have value, but are not included in the above disclosures. These include,
among other items, the estimated earnings power of core deposit accounts, the
earnings potential of loan servicing rights, the value of a trained work force,
customer goodwill and similar items.
