                    INTEGRA BANK CORPORATION and Subsidiaries

         UNAUDITED NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1

The accompanying unaudited condensed consolidated financial statements include
the accounts of Integra Bank Corporation (formerly National City Bancshares,
Inc.) and its subsidiaries (collectively, the "Corporation"). At June 30, 2000,
the Corporation had as subsidiaries, eight 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 accounting principles generally accepted in the
United States 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 Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 133,(SFAS 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, as
amended by SFAS 138, 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 which 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 various other outstanding
commitments and contingent liabilities which 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 following table reflects commitments and contingent liabilities not
reflected in the financial statements with dollars in thousands:


                                       June 30, 2000     December 31, 1999

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
Corporation's annual report for the year ended December 31, 1999. The
Corporation evaluates performance based on profit or loss from operations before
income taxes not including nonrecurring gains and losses. Operating statistics

The Corporation is in process of consolidating its subsidiary banks into one
banking charter which is expected to be completed by the end of the third
quarter. As a result, the Corporation is changing its organizational structure
from a geographical structure to a structure organized around lines of business.
The structure will consist of three lines of business divisions, Retail Banking,
Commercial Banking, and Trust and Investment Services. This transition to the
new organizational structure is currently underway and is expected to be
completed on or before January 1, 2001. The change in structure will also result
in a change in reportable segments in future financial reporting periods.

NOTE 7

A subsidiary of the Corporation sponsored an employee stock ownership plan
(ESOP) that covered certain eligible employees. During the first quarter of
2000, the Corporation made the final distribution of all shares from the ESOP
and closed out the plan.

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 Integra Bank Corporation and its subsidiaries as presented in the
condensed consolidated financial statements and related notes. 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.

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 devoted significant resources in 2000 towards the
combination of its banking subsidiaries into one bank under the name Integra.
The Corporation has established a three phase plan for completion of the
project. The first phase of the project was completed on May 19, 2000, the
second phase was completed on July 14, 2000 and the final phase is scheduled to
be completed September 15, 2000. It is anticipated that the Corporation will
incur total costs of approximately $1.8 million in connection with the
consolidation and the name change.

On July 5, 2000 the Corporation announced that it had signed a definitive
agreement to acquire Webster Bancorp, Inc. (Webster), headquartered in Clay,
Kentucky. At March 31, 2000, Webster reported total assets of $294.0 million,
deposits of $251.0 million and shareholders' equity of $20.0 million. Under the
terms of the agreement the Corporation would exchange approximately 1,750,000
shares of its common stock for all of the issued and outstanding shares of
Webster. The transaction is subject to regulatory approval, approval by
Webster's shareholders, and certain other conditions. The transaction is
expected to close in the first quarter of 2001 and will be accounted for as a
purchase. The Corporation also announced that its Board of Directors had
approved the purchase of approximately 1,750,000 shares of its common stock in
the open market and in private transactions to facilitate the purchase.

NET INCOME

Net income for the quarter ended June 30, 2000 was $7.8 million compared to $7.5
million in the second quarter of 1999, an increase of $0.3 million, or 4.3%.
Basic earnings per share for the second quarter were $0.45 in 2000 compared to
$0.42 in 1999. Earnings per share, on a diluted basis was $0.45 for the second
quarter of 2000 compared to $0.42 in 1999.

For the six months ended June 30, 2000, net income was $15.7 million compared to
$14.2 million in the prior year, an increase of $1.5 million, or 10.6%. Basic
earnings per share for the first six months were $0.90 in 2000 compared to $0.80
in 1999. Earnings per share, on a diluted basis, were $0.90 for 2000 compared to
$0.79 in 1999.

The basic weighted average number of shares outstanding was 17,413,209 and
17,452,656 for the three and six months, respectively, ended June 30, 2000,
compared to 17,733,154 and 17,707,924 during the same periods last year. The
weighted average number of shares outstanding, assuming dilution, was 17,425,766
and 17,475,963 for the three and six months ended June 30, 2000, respectively,
compared to 17,798,208 and 17,775,387 during the same periods in the prior year.
The reduction in the number of average shares outstanding is due to the
Corporation's purchase of approximately 440,000 shares of common stock under its
stock repurchase program which was announced in October 1999.

The average return on equity for the second quarter of 2000 was 13.76%
reflecting a 0.71% increase from the second quarter of 1999. The average return
on equity for the six months ended June 30 was 13.94% and 12.67% in 2000 and
1999, respectively.

NET INTEREST INCOME

Net interest income, on a taxable equivalent basis, for the quarter ended June
30, 2000 was $24.5 million, reflecting an increase of $463,000 or 1.9% compared
to the same period in 1999. The increase was principally due to an increase in
average earning assets in the second quarter of 2000, compared to same quarter
of the prior year. Average earning assets were $2,241.2 million for the second
quarter of 2000 compared to $1,988.9 million for the same quarter of the prior
year. The majority of the increase in earning assets was in the securities
portfolio, which increased $190.7 million over the second quarter of 1999.
Average loans were $1,696.0 million in the second quarter of 2000, compared to
$1,624.6 million in the second quarter of 1999, reflecting a $71.4 million, or
4.4% increase. The growth in average earning assets was funded primarily through
an increase in short-term and other borrowings (borrowings). The average balance
for borrowings was $365.6 million for the second quarter of 2000, compared to
$209.4 million for the same period in the prior year. Net interest income on a
taxable equivalent basis, as a percentage of earning assets (net interest
margin) for the second quarter was 4.40% in 2000 and 4.85% in 1999.

For the six months ended June 30, 2000, net interest income, on a taxable
equivalent basis, was $47.9 million compared to $47.7 million for the same
period in 1999, primarily due to increases in volume of average earning assets.
Average earning assets for the first six months of 2000 were $2,155.2 million
compared to $1,996.6 million for the corresponding period in 1999, reflecting an
increase of $158.6 million or 8.0%. Average securities for the first six months
of 2000 increased $94.0 million over the same period in 1999. Average loans also
increased $77.0 million in the first half of 2000 compared to 1999. For the
first six months of 2000 average interest bearing deposits increased $39.0
million and average borrowed funds increased $156.0 million compared to 1999.

The net interest margin for the first six months of 2000 decreased 34 basis
points from 4.82% in 2000 to 4.48% in 1999. This decrease is principally due to
increased funding costs to support the growth of earning assets.

UNDERPERFORMING ASSETS

Listed below is a comparison of underperforming assets with dollars in
thousands.

Nonaccrual loans                $30,288              $32,025          $10,174
Restructured loans                1,236                1,275            1,278

-----------------------------------------------------------------------------
Total underperforming loans      33,916               34,929           13,301
Other real estate held            1,203                  936            1,051
-----------------------------------------------------------------------------
  Total underperforming loans  $35,119              $35,865          $14,352
-----------------------------------------------------------------------------
For the first six months of 2000 total underperforming loans decreased $1.0
million, or 2.9%. Past due 90 days or more, nonaccrual, and restructured loans
were 2.0%, 2.0% and 0.8% of total gross loans at June 30, 2000, December 31,
1999, and June 30, 1999, respectively.

PROVISION FOR LOAN LOSSES

Net charge-offs amounted to $1.9 million through June 30, 2000, compared to $1.6
million in the corresponding period in the prior year. Net charge-offs for the
second quarter were $1.1 million in 2000 and $0.2 million in 1999.

The provision for loan losses for the second quarter was $863,000 in 2000
compared to $841,000 for the same period in 1999, an increase of 2.6%. For the
six months ending June 30, 2000 and 1999 provision for loan losses was $1.9
million and $2.1 million, respectively. The provision for loan losses is
determined based on a quarterly review of the allowance for loan losses.
Management evaluates large credits and loans identified as problem loans on an
individual basis to identify the risk profile and probable losses of such loans.
All other loans are evaluated as homogeneous pools based on historical loss
experience and the provision is allocated accordingly. During the second quarter
there were no significant changes in loan concentrations, quality, or terms.
There were no material changes in estimation methods or assumptions affecting
the allowance, or reallocations of the allowance among the various parts of the
portfolio during the second quarter of 2000. As of June 30, 2000, management
considered the allowance for loan losses adequate for probable loan losses.

million in 1999. Securities transactions resulted in gains of $546,000 in the
second quarter of 2000 and in losses of $641,000 in the same period of 1999.
Total noninterest income excluding securities transactions was approximately
$3.8 million in the second quarter of 2000 and 1999.

NONINTEREST INCOME (continued)

For the six months ended June 30, 2000 noninterest income increased $2.8
million, or 39.2%, from the same period a year ago. During the first quarter of
2000 the Corporation recognized a gain of approximately $1.8 million on the sale
of its mortgage loan investor servicing rights. The Corporation had gains on
securities transactions of $509,000 during the first six months of 2000 and
losses of $638,000 for the corresponding period in 1999. Noninterest income for
the six months ending June 30 excluding securities gains or losses and the gain
on sale of mortgage servicing rights was $7.5 million in 2000 and $7.7 million
in 1999.

NONINTEREST EXPENSE

Noninterest expense increased $1.2 million, or 11.0%, in the second quarter of
2000 compared to the second quarter of 1999. Salaries and employee benefits
increased $1.2 million, or 18.0%; occupancy expense increased $15,000, or 1.7%;
expenses of furniture and equipment increased $26,000, or 2.4.%; amortization of
intangibles decreased $126,000, or 12.9%; and other noninterest expense
increased $437,000, or 10.1%, over the same period of 1999.

For the first six months of 2000 noninterest expense increased $1.5 million, or
5.2%, compared to the same period a year ago. Salaries and employee benefits
increased $1.6 million, or 11.1%; occupancy expense increased $78,000, or 4.5%;
expenses of furniture and equipment increased $67,000, or 3.3%; amortization of
intangibles decreased $128,000, or 6.4%; and other noninterest expense decreased
$53,000, or 0.6%, over same period in the prior year.

The increase in salaries and employee benefits for the second quarter of 2000
and for the first six months of the year compared to the prior year is primarily
due to a $877,000 settlement gain on termination of the Corporation's pension
plan which was recognized in the second quarter of 1999. Other noninterest
expense for the second quarter of 2000 increased primarily due to additional
advertising expense incurred in connection with the consolidation of subsidiary
bank charters and the name change to Integra.

FINANCIAL POSITION

During the first six months of 2000 cash and cash equivalents decreased $20.6
million, or 28.2% and federal funds sold increased $853,000 or 114.0% from
December 31, 1999.

Total investment securities increased $309.6 million, or 93.1%, from the year
ended 1999, the largest increase of $274.4 million, was in mortgage-backed
securities. U.S. Government and agency securities increased $54.5 million, or
74.3%; tax-exempt municipal securities decreased $36.3 million, or 19.9% The
market value adjustment on total securities available for sale at June 30, 2000,
was an unrealized loss of $4.5 million, compared to the unrealized loss of $2.8
million at December 31, 1999. This change was primarily due to increases in
interest rates since the 1999 year-end.

In 2000 the Corporation increased its portfolios of mortgage-backed and U. S.
Government and agency securities and funded this growth, principally, through
wholesale borrowings to improve earnings. This strategy is designed to earn
incremental revenue from excess capital not presently utilized to support other
areas of the Corporation's banking operations. As of June 30, 2000 total assets
had been increased by approximately $400 million as a result of this strategy.
In order to reduce the potential negative impact of raising interest rates on
this strategy, the Corporation has entered into interest rate caps with
aggregate notional values of approximately $100 million.

LIQUIDITY AND CAPITAL RESOURCES

The Corporation and its subsidiaries require sufficient liquidity to make new
loans, to accommodate possible outflows of deposits, to repay borrowings at
maturity, and to take advantage of attractive investment opportunities. The
Corporation's primary sources have been federal funds sold and securities
available for sale. Liquidity is also available to the Corporation through
federal funds purchased, repurchase agreements Federal Home Loan Bank advances
and brokered deposits. The Corporation and its subsidiaries have adequate
liquidity to meet their operating needs.

Integra Bank Corporation (parent company) obtains liquidity from the receipt of
dividends and fees from subsidiary banks, money market deposits and available
for sale securities. As a supplemental source of liquidity the Corporation
entered into a $50 million line of credit agreement with a group of lenders
which matures on June 29, 2001. The Corporation plans to draw on this line as
required for general corporate purposes including possible acquisitions.
Management believes that the parent company has sufficient cash resources to
meet its cash needs.
