                 NATIONAL CITY BANCSHARES, INC. and Subsidiaries

         UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1

The accompanying unaudited condensed consolidated financial statements include
the accounts of National City Bancshares, Inc. and its subsidiaries
(collectively, the "Corporation"). At March 31, 2000, the Corporation had as
subsidiaries, twelve commercial banks, a leasing corporation, a property
management company, and a Delaware statutory business trust. All significant
intercompany transactions are eliminated in consolidation.

The financial statements have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission ("SEC"). While the
financial statements are unaudited, they do reflect all adjustments which, in
the opinion of management, are necessary for a fair statement of the financial
position, results of operations, and cash flow for the interim periods. All such
adjustments are of a normal recurring nature. Pursuant to SEC rules, certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted from these financial statements unless significant changes
have taken place since the end of the most recent fiscal year. The accompanying
financial statements and notes thereto should be read in conjunction with the
Corporation's financial statements and notes for the year ended December 31,
1999 included in the Corporation's Annual Report on Form 10-K filed with the
SEC.

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

ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

On June 15, 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS 133 established a new model for
accounting for derivatives and hedging activities and supersedes and amends a
number of existing standards. SFAS 133 is effective for fiscal years beginning
after June 15, 2000, but earlier application is permitted as of the beginning of
any fiscal quarters subsequent to June 15, 1998. Upon the statement's initial
application, all derivatives are required to be recognized in the statement of
financial position as either assets or liabilities and measured at fair value.
In addition, all hedging relationships must be designated, reassessed, and
documented pursuant to the provisions of SFAS 133. Adoption of SFAS 133 is not
expected to have a material financial statement impact on the Corporation's
financial position or operating results.


NOTE 2

The Corporation and its subsidiaries are parties to legal actions that arise in
the normal course of their business activities. In the opinion of management,
the ultimate resolution of these matters is not expected to have a materially
adverse effect on the financial position or on the results of operations of the
Corporation and its subsidiaries.

In the normal course of business, there are outstanding various other
commitments and contingent liabilities that are not reflected in the
accompanying financial statements. The Corporation uses the same credit policies
in making commitments and conditional obligations as it does for other
instruments.

The Corporation has identified its reportable segments on the basis of the
geographic areas served by the Corporation. Banking services offered are similar
in each geographic area served. The accounting policies of the segments are the
same as those described in the summary of significant accounting policies in the

Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations


INTRODUCTION

The discussion and analysis which follows is presented to assist in the
understanding and evaluation of the financial condition and results of
operations of National City Bancshares, Inc. and its subsidiaries as presented
in the condensed consolidated financial statements and related notes included in
this report. The text of this review is supplemented with various financial data
and statistics. All information has been restated to include bank acquisitions
accounted for using the pooling of interests method and to give effect to all
stock dividends. Unless otherwise noted all dollar amounts other than per share
data are in thousands (000's).

Certain statements made in this report may constitute "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. Such forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause the actual results, performance
or achievements to be materially different from the results, performance or
achievements expressed or implied by such forward-looking statements. Such
factors include, among others, the following: management's ability to
effectively implement the Corporation's strategic plan; general, regional and
local economic conditions which may affect interest rates and net interest
income; credit risks and risks from concentrations (geographic and by industry)
within the loan portfolio; changes in regulations affecting financial
institutions; and competition.

The Corporation has not made any acquisitions since January 1, 2000; however
management evaluates acquisition opportunities as they arise. The Corporation
has devoted significant resources in 2000 towards the combination of its twelve
banking subsidiaries into one bank under the name Integra. This project is
expected to be completed in three phases commencing May 19, 2000 with an
anticipated completion date by the end of the third quarter of 2000. It is
anticipated that the Corporation will incur total costs of approximately $1.8
million in connection with the consolidation and name change.

NET INCOME

Net income for the quarter ended March 31, 2000 was $7,882 compared to $6,705 in
the first quarter of 2000, an increase of $1,117, or 17.6%. Basic earnings per
share for the first quarter were $0.45 in 2000 compared to $0.38 in 1999.
Earnings per share on a diluted basis for the first quarter were $0.45 in 2000
compared to $0.37 in 1999.

The weighted average number of shares outstanding was 17,492,103 and 17,682,413
for the three months ended March 31, 2000, and 1999, respectively. The weighted
average number of shares outstanding, assuming dilution, was 17,533,665 and
17,752,313 for the three months ended March 31, 2000 and 1999, respectively.

NET INTEREST INCOME

Net interest income, on a taxable equivalent basis, for the quarter ended March
31, 2000 was $23,429, reflecting a decrease of $272 or 1.2% over the same period
in 1999. The net interest margin decreased 23 basis points from 4.79% in the
first quarter of 1999 to 4.56% in the first quarter of 2000. The decrease in net
interest margin was primarily due to a higher cost of borrowing.

Average earning assets, for the first quarter of 2000, increased $64,035, or
3.2% over the same period last year. Gross loans increased an average of
$82,785, or 5.1%; average securities decreased $2,303, or 0.6%; and average
federal funds sold decreased $15,092, or 53.7%. Average interest-bearing
liabilities for the first quarter of 2000 increased $101,332, or 6.1%. Average
interest-bearing deposits increased $54,324, or 3.7%, and average borrowings
increased $47,008, or 22.5%, compared to the same period last year.

NONINTEREST INCOME

Noninterest income, excluding gains or losses on securities transactions,
totaled $5,447 and $3,810 for the first three months in 2000 and 1999,
respectively. During the first quarter of 2000, the Corporation sold its
mortgage loan investor servicing rights and recognized a gain of $1,816,
compared with loan gains and other non-recurring items of $429 during the first
quarter of 1999.

NONINTEREST EXPENSE

Noninterest expense for the first quarter of 2000 totaled $14,832, a decrease of
$28, or 0.2%, compared to the prior year. Upward pressures on expense
categories, such as salaries and consolidation costs, were offset through cost
control measures implemented in other expense categories.

NON-PERFORMING ASSETS

Non-performing assets consist of nonaccrual loans, restructured loans, loans
past due 90 days or more, and other real estate owned. Nonaccrual loans are
loans on which interest recognition has been suspended because of doubts as to
the borrower's ability to repay principal or interest. Loans are generally
placed on nonaccrual status after becoming 90 days past due if the ultimate
collectibility of the loan is in question. Loans which are current, but as to
which serious doubt exists about repayment ability, may also be placed on
nonaccrual status. Restructured loans are loans where the terms have been
changed to provide a reduction or deferral of principal or interest because of
the borrower's financial position. Past-due loans are loans that are continuing
to accrue interest but are contractually past due ninety days or more as to
interest or principal payments. Other real estate owned represents properties
obtained for debts previously contracted. Management is not aware of any loans
which have not been disclosed as non-performing assets that represent or result
from unfavorable trends or uncertainties which management reasonably believes
will materially adversely affect future operating results, liquidity, or capital
resources, or represent material credits as to which management has serious
doubt as to the ability of such borrower to comply with loan repayment terms.

Listed below is a comparison of non-performing assets.

The Corporation monitors credit quality through a periodic review and analysis
of each subsidiary bank's loan portfolio. On a quarterly basis, the
Corporation's credit administration department performs an evaluation of the
adequacy of its allowance for loan losses. The evaluation includes an analysis
of past due loans, loans criticized during regulatory examinations, internally
classified loans, delinquency trends, and other relevant factors. The results of
these evaluations are used by the Corporation to determine the adequacy of the
consolidated allowance for loan losses.

PROVISION FOR LOAN LOSSES

The provision for loan losses is the amount necessary to adjust the allowance
for loan losses to an amount that is adequate to absorb estimated loan losses as
determined by management's periodic evaluations of the loan portfolio. This
evaluation by management is based upon consideration of actual loss experience,
changes in composition of the loan portfolio, evaluation of specific borrowers
and collateral, current economic conditions, trends in past-due and non-accrual
loan balances and the results of recent regulatory examinations.

The provision for loan losses totaled $1,050 for the first three months of 2000,
a decrease of $210 from the $1,260 provided in the first three months of 1999.
During the fourth quarter of 1999, management centralized the process for
evaluating the adequacy of the allowance for loan losses. As part of this
process, and also in response to unfavorable trends in delinquencies and
non-performing assets, the Corporation performed an extensive credit risk
assessment of the Corporation's loan portfolio. The results of this assessment
revealed the need to increase the allowance for loan losses by $7,800 during the
fourth quarter of 1999. At March 31, 2000, the allowance for loan losses as a
percentage of loans was 1.50% compared to 1.14% for the same period last year.
The allowance for loan losses to non-performing loans at March 31 was 72.6% in
2000 and 144.1% in 1999.

FINANCIAL POSITION

During the first three months of 2000 cash and cash equivalents decreased
$24,456, or 33.5%, and federal funds sold increased $5,268, or 704.3%, from
December 31, 1999.

Total investment securities increased $98,975, or 29.8%, from the year ended
1999. The increase was primarily in mortgage-backed securities as the
Corporation has continually worked on improving its liquidity position.
Mortgage-backed securities increased $95,195, or 210.2%, from year end. This
growth was accomplished through increased borrowings and the reductions in the
tax-exempt municipal securities holdings.

Amortized cost and fair values of securities available for sale at March 31,
2000 are as follows:

$22,524, or 10.8%, and interest-bearing deposits increased $21,106, or 1.4%,
during the three months ended March 31, 2000.

$86,842, or 62.7%, over the corresponding balance at December 31, 1999. The
increase, primarily fixed rate Federal Home Loan Bank advances, was a result of
the Corporation's interest rate risk management program and to fund asset
growth.

IMPACT OF ACCOUNTING PRONOUNCEMENTS

On June 15, 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS 133 established a new model for
accounting for derivatives and hedging activities and supersedes and amends a
number of existing standards. SFAS 133 is effective for fiscal years beginning
after June 15, 2000, but earlier application is permitted as of the beginning of
any fiscal quarters subsequent to June 15, 1998. Upon the statement's initial
application, all derivatives are required to be recognized in the statement of
financial position as either assets or liabilities and measured at fair value.
In addition, all hedging relationships must be designated, reassessed, and
documented pursuant to the provisions of SFAS 133. Adoption of SFAS 133 is not
expected to have a material financial statement impact on the Corporation's
financial position or operating results.
