ITEM 1 - DESCRIPTION OF BUSINESS

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. (the "Finance Company"). On
December 24, 1997, approval was granted by the Ohio Division of Financial
Institutions for Advantage Finance, Inc. to do business. On April 13, 1998, the
Finance Company opened for business at 117 North Greenwood, Suite 7, Marion,
Ohio providing finance company services to customers in the Marion area.

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 acceptance of deposits for demand, savings and time
accounts and 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 nonmember
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 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 based on 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 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 made with primarily fixed
rates and are secured by the borrower's residence. Such loans are made based on
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
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 

                                                                             3.

ITEM 1 - DESCRIPTION OF BUSINESS (Continued)

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 Finance Company specializes in direct and indirect lending for
consumer goods, 90-day and six-month same-as-cash loans, second mortgage and
home equity loans, and installment loans.

Both the Bank and the Finance Company compete for business in the tri-county
market of Wyandot, Hancock and Marion Counties, Ohio. The Company's competitors
for business come from two primary sources: large regional firms such as
BankOne, National City BancCorp, Fifth Third BancCorp, Associates Finance,
Beneficial Finance and Sky Financial; and independent community banks and
thrifts such as First Citizen's National Bank, Fahey Bank and Industrial Savings
& Loan. The Bank finds that it competes favorably with the large regional banks
by its ability to maintain decision-making officers within branch locations
rather than centralizing decision-making in a corporate headquarters.
Competition with the independent community banks is enhanced by creating product
niches so as not to resort solely to pricing as a means to attract business.
Examples of the Bank's product niches include horse and cargo trailer financing,
small-business lending and low-fee demand deposit accounts. The Finance Company
has found a niche in indirect financing of retail consumer goods from regional
retailers such as Quality Farm and Fleet and Simplicity Tractors.

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 before approving any commercial real estate loan
with such potential risk.

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

FORWARD-LOOKING STATEMENTS

Certain statements contained in this report that are not historical facts are
forward-looking statements that are subject to certain risks and uncertainties.
When used herein, the terms "anticipates," "plans," "expects," "believes" and
similar expressions as they relate to the Corporation or its management are
intended to identify such forward-looking statements. The Corporation's actual
results, performance or achievements may materially differ from those expressed
or implied in the forward-looking statements. Risks and uncertainties that could
cause or contribute to such material differences include, but are not limited
to, general economic conditions, interest rate environment, competitive
conditions in the financial services industry, changes in law, unforeseen
business risks related to Year 2000 computer systems issues, government policies
and regulations and rapidly changing technology affecting financial services.

RESULTS OF OPERATIONS

Net income of $1,616,908 in 1998 represents a 12.1% decrease from the net income
of $1,839,057 in 1997. Diluted earnings per share decreased proportionately from
$1.76 in 1997 to $1.53 in 1998. The major factors that have influenced these
results are discussed below.

NET INTEREST INCOME

Net interest income, the primary source of earnings for the Commercial
Bancshares, Inc. (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 on the next page indicates that,
as of December 31, 1998, rate sensitive assets exceed rate sensitive liabilities
in the one year or less time horizon by approximately $1,486,000. Management
believes this places the Corporation in a desirable position for 1999 as the
Company's interest margin should not be significantly impacted by moderate
fluctuations in interest rates. For purposes of the GAP table, management has
included passbook savings and NOW checking accounts in the one through five-year
and over-five-year periods. 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 has 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 gives management flexibility in timing future rates
increases to these products.

(a)  Loans and mortgage-backed securities are assumed to adjust based on their
     contractual terms, with no assumptions as to repayments.

(b)  Management has included these accounts in the one through five and over
     five years time horizons based on past experience with rate adjustments on
     these accounts.

(c)  GAP is defined as rate sensitive assets less rate sensitive liabilities and
     may be expressed in dollars or as a percentage.

While the volume of both earning assets and interest-bearing liabilities
increased in 1998, differences in rates and deposit mix served to offset the
impact to net interest income. The average yield on earning assets decreased
from 8.33% in 1997 to 8.26% in 1998. The major factors were a decrease in the
yield on securities and a slight decrease in the yields on loans. Management
continued its emphasis on commercial loans, which is reflected in the portfolio
growth of approximately $18,491,000. To remain competitive, loans were priced
very aggressively and an overall decline in loan pricing was seen in 1998. In
addition, the installment loan portfolio increased $7,863,000 in 1998. The
increase was primarily in the indirect loan portfolio. This increase is due to a
change in management's focus from lower-yielding automobile loans to loans on
horse trailers, which generally have higher yields and longer maturities. Charge
offs on installment loans have been high in the past; however, management does
not anticipate an increased level of charge offs to continue. The Bank has
strategically targeted managed growth in the commercial and indirect areas for
1999. Alternative lower cost sources of funds such as Federal Home Loan Bank
advances and federal funds purchased are available, if needed, to fund this
growth.

NET INTEREST INCOME (Continued)

Management continues to closely monitor net interest income, while maintaining
competitive loan and deposit rates in the markets served. Although no one can
accurately predict future movement in interest rates, management expects a
continued stable to slightly lower rate environment for 1999.

ALLOWANCE AND PROVISION FOR POSSIBLE LOAN LOSS

0.75% of total loans. This compares to $1,075,385 or .85% of total loans in
1997. 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 $472,000 to the allowance for loan losses in 1998 to
maintain the allowance balance at an adequate level following charge-offs of
$467,000 and recoveries of $103,000. The provision for allowance for loan losses
was $141,000 lower than 1997 due to management's decreased activity in the
riskier, indirect automobile market.

The following schedule presents analysis of the allowance for loan losses,
average loan data, and related ratios for the years ended December 31, 1998 and
1997.

The allowance for possible loan losses is maintained by management at a level
considered adequate to cover probable 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.

</TABLE>

Nonaccrual loans totaled $1,168,537 at December 31, 1998 as compared to
$1,073,000 at December 31, 1997. Management believes nonaccrual loans are
adequately reserved for 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.

</TABLE>

No interest income was recognized on impaired loans in 1998 and 1997.

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, 1998, the balance in OREO was $921,500,
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 $2,021,605 was 0.74% higher than the 1997 figure of
$2,006,696. Noninterest income for 1997 included a gain on the sale of the
property, equipment and deposits of the Kenton branch. This was offset in 1998
by an increase in overdraft fees and loan servicing income for loans sold. An
additional contributor to noninterest income was a $184,709 increase in net
gains on sale of securities and an increase of $360,871 in net gains on loan
sales due to increased activity in this area.


NONINTEREST EXPENSE

Total noninterest expense increased $648,126 in 1998. Customary merit increases
of employee salaries; the addition of three executive officers; and increases in
professional fees were offset by a reduction in data processing expense.

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

                                                                              9.
<PAGE>   12



INCOME TAXES

Income tax expense of $426,210 in 1998 represents 20.9% of income before taxes
compared to 24.8% in 1997. These effective tax rates are both lower than the
statutory rate of 34%, primarily resulting from the Bank's investment in
tax-exempt obligations from states and political subdivisions. Tax exempt income
from securities represented 6.05% and 5.38% of total interest income in 1998 and
1997.


FINANCIAL CONDITION

TOTAL ASSETS

Total assets increased to $210,403,732, or 16.01%, at December 31, 1998 from
$181,366,767 at December 31, 1997. Net loans increased $32,569,729 or 26.08%
while securities did not significantly change. Cash and cash equivalents
decreased 5.89% from 1997.

The Corporation received approval from the appropriate regulatory agencies in
1997 to form a finance company, Advantage Finance, Inc. (Advantage), in Marion,
Ohio. The purpose of Advantage is to provide financing for higher-risk borrowers
not meeting the more stringent underwriting criteria of the Bank. Operations
began in the second quarter of 1998, with Advantage operating as a subsidiary of
the Corporation. In January 1999, the Corporation received regulatory approval
to establish Advantage as a subsidiary of the Bank to facilitate its future
operations. At December 31, 1998, Advantage had loans made to customers of
$496,000.

Management has purchased a building to establish an additional branch in Marion,
Ohio and has plans to expand and remodel several existing branches in 1999.
Capital expenditures are expected to approximate $500,000 related to these
projects. As these projects are completed and staffed, management expects that
occupancy expense, salaries and benefits and other expenses related to
operations will increase.


LOANS

Consumer and credit card loans increased $7,862,730 or 23.02% from 1997 levels.
The Corporation was active in the indirect loan business, specifically loans for
horse trailers, which accounted for substantial consumer loan growth in 1998.
Commercial loans were increased 30.47% in 1998 through the Corporation's
Business Development Team and strategically lower interest rates. Management is
committed to strengthening business relationships and providing incentives for
loan growth.

                                                                             10.
<PAGE>   13



LOANS (Continued)

Real estate loans showed an increase of $5,657,954, or 22.56%, which primarily
represents one-to four-family loans. Loans originated for sale in the secondary
market and still retained by the Bank at year end are classified as loans held
for sale and are carried at the lower of cost or fair value and were
approximately $2,276,000 and $5,191,000 at December 31, 1998 and 1997. 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 $46,931,540 as of December 31, 1998, compared to $23,411,756 as of
December 31, 1997. At December 31, 1997, other assets include a receivable of
approximately $3,508,000 for loans sold.

The Bank's loan portfolio represents it 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.

terms, excluding real estate mortgage and installment loans, rounded to the

agencies decreased $1,600,000 or 37.83%; and obligations of state and political
subdivisions increased $2,469,000 or 22.30% in 1998. Securities were sold to
fund the Bank's increased loan demand.

In order to provide additional liquidity for loan growth in 1998, management
sold its remaining obligations of federal agencies classified as held to
maturity. Management does not anticipate classifying securities as held to
maturity in the foreseeable future.

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 Home Loan 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 increased $11,297,000, or 6.98%. Management concentrated on
producing a sales culture in the Corporation during 1998. The increase in
deposits is primarily the result of sales goals and incentives at the branches
instead of rate specials.

CAPITAL RESOURCES

Total shareholders' equity at December 31, 1998 was $17,047,628 an increase of
$1,359,285 or 8.66% from total shareholders equity of $15,688,343 at December
31, 1997. The increase is primarily due to 1998 net income of $1,616,908 offset
by the Corporation's dividend payout which amounted to $775,173 for the year
ended December 31, 1998. An additional contributor to the increase in
shareholders' equity was the higher market value of the Bank's
available-for-sale investment portfolio, which shows an unrealized gain of
$142,983 (net of tax) at December 31, 1998 compared to an unrealized loss of
$226,210 (net of tax) at December 31, 1997.

Banking regulations have established minimum capital requirements for banks
including risk-based capital ratios and leverage ratios. As of December 31,
1998, 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, 1998, the Bank's total risk-based capital ratio and leverage
ratio were 11.6% and 8.1%, thus exceeding the minimum regulatory requirements.
At December 31, 1997, the ratios were 13.2% and 8.4%.

The Corporation has similar capital requirements on a consolidated basis as
described in Note 12 of the consolidated financial statements.

                                                                             13.

CAPITAL RESOURCES (Continued)

The Corporation's Board of Directors declared cash dividends of $.37 per share
in May, $.18 per share in August and $.19 per share in November of 1998, paying
a total of $775,173. The Corporation's 1998 return on average shareholder equity
was 10.62% compared to 12.49% in 1997. Total cash dividends paid in 1998
represented 47.94% of 1998 net income. This compares to a dividend payout ratio
of 39.64% in 1997.


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 $6,692,802 at December 31, 1998 and $7,111,986 at
December 31, 1997. These assets provide the primary source of liquidity for the
Bank. In addition, the Bank has designated 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, 1998 and 1997,
the ratio of loans (net of unearned income) to deposits and borrowed funds was
82.49% and 76.42%, 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.

YEAR 2000

The Corporation uses a third-party data processing center, which also provides
data processing services to other financial institutions. The Corporation's
lending and deposit activities are almost entirely dependent on computer systems
which process and record transactions, although the Corporation can effectively
operate with manual systems for brief periods when its electronic systems
malfunction or cannot be accessed. In addition to its basic operating
activities, the Corporation's facilities and infrastructure, such as security
systems and communications equipment, are dependent, to varying degrees, on
computer systems.

The Corporation is aware of the potential Year 2000 related problems that may
affect the computers that control or operate the Corporation's operating
systems, facilities and infrastructure. In 1997, the Corporation began a process
of identifying any Year 2000 related problems that may be experienced by its
computer-operated or computer-dependent systems. Each application has been
identified as "Mission Critical" or "Nonmission Critical." The Corporation has
contacted the companies that supply or service the Corporation's
computer-operated or computer-dependent systems to obtain confirmation that each
system that is material to the operations of the Corporation is either currently
Year 2000 compliant or is expected to be Year 2000 compliant. With respect to
systems that cannot presently be confirmed as Year 2000 compliant, the
Corporation will continue to work with the appropriate supplier or servicer to
ensure all such systems will be rendered compliant in a timely manner, with
minimal expense to the Corporation or disruption of the Corporation's
operations. All of the identified computer systems affected by the Year 2000
issue are currently in the renovation, validation or implementation phase of the
process of becoming Year 2000 compliant. As a contingency plan, however, the
Corporation has determined that if the Corporation's systems fail the
Corporation would implement manual systems until such systems could be
re-established. The Corporation does not anticipate that such short-term manual
systems would have a material adverse effect on the Corporation's operations. At
this time, however, the expense that may be incurred by the Corporation in
connection with system failure related to the Year 2000 issue cannot be
determined.

In addition to the possible issues related to its own systems, the Corporation
could incur losses if loan payments are delayed due to Year 2000 problems
affecting any of the Corporation's significant borrowers or impairing the
payroll systems of large employers in the Corporation's primary market area.
Because the Corporation's loan portfolio is highly diversified with regard to
individual borrowers and types of businesses and the Corporation's primary
market area is not significant dependent on one employer or industry, the
Corporation does not expect any significant or prolonged Year 2000 related
difficulties will affect net earnings or cash flow. At this time, the expense
that may be incurred by the Corporation in connection with Year 2000 issues
confronting its customers cannot be determined.

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

                                                                              
NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION: The consolidated financial statements include the
accounts of Commercial Bancshares, Inc. (Corporation) and its wholly owned
subsidiaries, The Commercial Savings Bank (Bank) and Advantage Finance, Inc.
(Advantage). All significant intercompany balances and transactions have been
eliminated in consolidation.

INDUSTRY SEGMENT INFORMATION: Commercial Bancshares, Inc. is a bank-holding
corporation whose banking subsidiary, The Commercial Savings Bank, is 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. Advantage Finance, Inc. is a consumer finance company operating in
Marion, Ohio. These market areas provide the source of substantially all of the
Corporation's deposit and loan activities, although some indirect loans are made
to borrowers outside the Corporation's immediate market area. Substantially all
of the Corporation's income is derived from commercial and retail lending and
investments activities.

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 1998 and 1997, the
Corporation paid $7,275,410 and $7,370,171 in interest and $400,000 and $445,000
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 1998 and 1997, 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.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

LOANS HELD FOR SALE: Certain residential mortgage loans are originated for sale
in the secondary-mortgage loan market. These loans are included in real estate
loans and are carried at the lower of cost or estimated fair value in the
aggregate. Net unrealized losses are recognized through a valuation allowance by
charges to income. To mitigate 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.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

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 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 50% and 48% of the loan
portfolio at year-end 1998 and 1997 and the loans are expected to be repaid from
cash flow from operations of the borrower. Real estate mortgages make up
approximately 23% and 25% of the loan portfolio at year-end 1998 and 1997 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% of total loans at year-end 1998 and 1997.
Consumer loans include new and used automobile and other consumer purpose loans.
Consumer loans make up approximately 25% and 26% of total loans at year-end 1998
and 1997. The Bank also originates consumer-oriented purchase-money loans
indirectly through various automobile, motorcycle, boat, horse trailer,
recreational vehicle and other dealerships. Indirect loans represented 77% and
92% of consumer loans and 20% and 24% of total loans at year-end 1998 and 1997.
Unsecured loans represented 1% and 2% of total loans at year-end 1998 and 1997.

At year-end 1998 and 1997, the Bank had due from bank balances and overnight
federal funds sold to National City Bank totaling $3,975,000 and $4,680,000,
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. 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.

</TABLE>

Amortization expenses totaled $18,693 in 1998 and $54,680 in 1997. 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 in 1997.

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.

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. Mortgage servicing rights
totaled $534,069 at year-end 1998 and $193,417 at year-end 1997, 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.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

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.

COMPREHENSIVE INCOME: Comprehensive income consists of net income and other
comprehensive income. Other comprehensive income includes unrealized gains and
losses on securities available for sale, which are also recognized as separate
components of equity. The accounting standard that requires reporting
comprehensive income first applies for 1998, with prior information restated to
be comparable.

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 1,045,973 and 1,041,456 weighted average shares
outstanding during the years ended December 31, 1998 and 1997. Diluted earning
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 1,056,939 in 1998 and
1,043,391 in 1997.

In May 1997, the Board of Directors declared a three-for-one stock split,
resulting in the issuance of 694,304 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 to the current presentation.

The amortized cost and approximate fair value of debt securities available for
sale at year-end 1998, by contractual maturity, are shown below. Expected
maturities will differ from contractual maturities because issuers may have the
right to call or prepay obligations with or without call or prepayment
penalties. Debt securities not due at a single maturity date, primarily
mortgage-backed securities, are shown separately.

NOTE 9 - STOCK OPTION PLAN

The Commercial Bancshares, Inc. Incentive Stock Option Plan was approved by
shareholders in April 1997. The plan enables 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. 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 based on financial performance
can operate to shorten the vesting time and were approved by the Board of
Directors with the initial grant in June 1997. 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:

During 1997, the Corporation met one of the exceptions to the vesting schedule

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 thirty days 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 $96,124 and $66,646 for the years ended
December 31, 1998 and 1997.


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.

NOTE 11 - COMMITMENTS, OFF-BALANCE SHEET RISK AND CONTINGENCIES  (Continued)

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.

The following is a summary of commitments to extend credit at year-end 1998 and
1997:

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 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:

The Corporation and Bank at year-end 1998 and 1997 were categorized as well
capitalized. Management believes that no events have occurred since the last
regulatory determination that would change the capital category at December 31,
1998.

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 1998, approximately $2,638,000
of the Bank's retained earnings was 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.


NOTE 13 - RELATED PARTY TRANSACTIONS

Certain directors, executive officers and principal shareholders of the
Corporation, including their immediate families and companies in which they are
principal owners, were loan customers during 1998 and 1997.

NOTE 14 - FAIR VALUES OF FINANCIAL INSTRUMENTS (Continued)

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 1998 or 1997, 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, 1998
and 1997 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.

         (1) Amounts have been restated for the effect of the 3-for-1 stock 
             split paid on June 30, 1997.


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 1,049,431 outstanding shares of common stock held by
approximately 1,417 shareholders as of December 31, 1998. In 1997, the
Corporation paid cash dividends in June and December resulting in a total amount
of $0.70 per share. In 1998, the Corporation paid cash dividends in June,
September and December totaling $0.74 per share.
