CITY NATIONAL BANCSHARES CORPORATION
Notes to Consolidated Financial Statements (Unaudited)

1.  Principles of consolidation

The accompanying consolidated financial statements include the accounts of City
National Bancshares Corporation (the "Corporation") and its subsidiary, City
National Bank of New Jersey (the "Bank" or "CNB"). All significant intercompany
accounts and transactions have been eliminated in consolidation.

2.  Basis of presentation

The accompanying unaudited consolidated financial statements have been prepared
in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation of
the financial statements have been included. Operating results for the three and
six months ended June 30, 2000 are not necessarily indicative of the results
that may be expected for the year ended December 31, 2000.

3.  Net income per common share

Basic income per common share is calculated by dividing net income less
dividends paid on preferred stock by the weighted average number of common
shares outstanding. On a diluted basis, both net income and common shares
outstanding are adjusted to assume the conversion of dilutive convertible
subordinated debentures.

Item 2

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

FINANCIAL CONDITION

Total assets at June 30, 2000 increased to $175.2 million from $172.5 million at
the end of 1999, due primarily to the acquisition of a branch office with $8.3
million in deposits from a savings bank in Roosevelt, New York, offset in part
by early redemptions of long-term debt by the Federal Home Loan Bank. The
acquisition was the Corporation's first interstate purchase and, as a result,
City National Bank of New Jersey became the second interstate minority-owned
bank in the country.

Investments

The investment securities available for sale ("AFS") portfolio increased
slightly to $36.4 at June 30, 2000 from $35.5 million at the end of 1999, while
the net related unrealized loss rose to $748,000 from $679,000. The investments
held to maturity("HTM") portfolio decreased to $30.9 million at June 30, 2000
from $33 million at the end of 1999 due primarily to maturities that were not
reinvested in the portfolio. The related unrealized loss in the HTM portfolio
declined from $2 million at the end of 1999 to $1.7 million at June 30, 2000 and
included $1.3 million attributable to $18.5 million of callable agency bonds.
Because of their call features, these bonds tend to reflect depreciation
regardless of bond market conditions as they will earn less than current issues
if interest rates rise, whereas if rates fall, they then may be redeemed at par
by the issuer. However, at the time of purchase, they have a higher coupon rate
than similar noncallable securities and the favorable spreads provide
compensation for the interest rate risk inherent in this investment due to the
call feature. Management believes that holding the callable securities will not
have a significant impact upon the financial condition or operations of the
Corporation.

Loans

Loans rose $2.8 million, to $85.3 million at June 30, 2000 from December 31,1999

Management believes that the reserve for loan losses is adequate based on an
ongoing evaluation of the loan portfolio. This evaluation includes consideration
of past loan loss experience, the level and composition of nonperforming loans,
collateral adequacy, and general economic conditions, including the effect of
such conditions on particular industries.

While management uses available information to determine the adequacy of the
reserve, future additions may be necessary based on changes in economic
conditions or in subsequently occurring events unforeseen at the time of
evaluation.

Nonperforming loans

Nonperforming loans include loans on which the accrual of interest has been
discontinued or loans which are contractually past due 90 days or more as to
interest or principal payments on which interest income is still being accrued
and nonaccrual loans. Delinquent interest payments are credited to income when
received. The following table presents the principal amounts of nonperforming
loans past due 90 days or more and accruing.

</TABLE>

Nonperforming assets are generally secured by small commercial real estate
properties. Nonaccrual loans declined significantly during the 2000 first half
due to the charge-off in the first quarter of $1.3 million of impaired loans to
a single borrower that had previously been restructured.

There were no impaired loans at June 30, 2000, while impaired loans totalled
$1.3 million at December 31,1999, all of which were charged off in the first
quarter of 2000. The related reserves allocated to these


                                       9
<PAGE>   10

loans amounted to $955,000 at December 31, 1999. Impaired loans averaged
$550,000 for the first half of 2000 and $190,000 for the first half of 1999.

DEPOSITS

Total deposits rose $10.6 million, or 7.6% to $150.4 million at June 30, 2000
from $139.8 million at the end of 1999, while average deposits rose 17.9%, to
$148.1.million for the first half of 2000 from $125.6 million for the first half
of 1999. The major sources of the growth in deposits were from the
aforementioned branch acquisition along with increased municipal time deposit
balances. Average demand deposits rose $3.7 million, or 17.9% due to increased
municipal and commercial account activity. Savings deposits rose to $61.2
million at June 30, 2000 from $34.7 million at the end of 1999, while time
deposits declined to $65.4 million at the end of June, 2000 from $84.5 million
at December 31, 1999. Both changes occurred due to shifts in municipal deposit
account balances.

The Bank's deposit levels may change significantly on a daily basis because
deposit accounts maintained by municipalities represent a significant part of
the Bank's deposits and are more volatile than commercial or retail deposits.
These municipal accounts represent a substantial part of the Bank's deposits,
tend to have high balance relationships and comprised most of the Bank's
accounts with balances of $100,000 or more at June 30, 2000. These accounts are
used for operating and short-term investment purposes. All the foregoing
deposits require collateralization with readily marketable U.S. Government
securities.

While the collateral maintenance requirements associated with the Bank's
municipal and U.S. Government account relationships might limit the ability to
readily dispose of investment securities used as such collateral, management
does not foresee any need for such disposal, and in the event of the withdrawal
of any of these deposits, these securities are readily marketable.

Short-term borrowings

While total short-term borrowings decreased from $6 million at December 31, 1999
to $2.5 million at the end of the 2000 second quarter, the average balances were
$2.9 million for the first six months of 1999 compared to $4.6 million for the
first half of 2000. These borrowings are comprised primarily of U.S. Treasury
tax and loan note option balances, which may be withdrawn at any time.

Long-term debt

Long-term debt decreased from $16.2 million at 1999 year-end to $11.7 million at
June 30, 2000, while average long-term debt declined from $15.7 million for the
first six months of 1999 to $12.4 million for the first half of 2000. The
decreases occurred due to early redemptions of callable Federal Home Loan Bank
advances.

Capital

Stockholders' equity amounted to $9.2 million at June 30, 2000 compared to $9
million at December 31,1999, while stockholders' equity as a percentage of total
assets was 5.27% at June 30, 2000 compared to 5.23% at December 31, 1999.

Risk-based capital ratios are expressed as a percentage of risk-adjusted assets,
and relate capital to the risk factors of a bank's asset base, including
off-balance sheet risk exposures. Various weights are assigned to different
asset categories as well as off-balance sheet exposures depending on the risk
associated with each. In general, less capital is required for less risk.

At June 30, 2000, the Corporation's core capital (Tier 1) and total (Tier 1 plus
Tier 2) risked-based capital ratios were 9.61% and 11.23%, respectively.

RESULTS OF OPERATIONS


                                       10
<PAGE>   11

Net income rose 39.1% to $256,000 for the second quarter of 2000 from $184,000
for the same 1999 quarter due primarily to an 11.9% increase in net interest
income. Related earnings per share on a diluted basis were $2.11 and $1.92. Net
income declined to $326,000 in the first half of 2000 from $513,000 for the
similar 1999 period due to an increased first quarter 2000 loan loss provision
compared to the first quarter of 1999. Related earnings per share on a diluted
basis decreased to $1.82 from $3.12.

Net interest income

In the first half of 2000, net interest income on a tax equialvent basis rose
5.2% from the same 1999 period, while the related net interest margins were
3.64% compared to 3.90%. The increased income resulted from higher levels of
earnings assets, while the lower interest margin was due to pressures from a
higher interest rate environment. Net interest income on a tax equivalent basis
rose 11.2% in the second quarter of 2000 compared to the second quarter of 1999,
while the net interest margin in the 2000 second quarter increased slightly to
3.89% compared to 3.86% a year ago.

Interest income on a tax equivalent basis rose 19.6% in the first half of 2000
compared to the first half of 1999 due to the increased earning asset levels.
Interest expense rose 35.6% between the same periods due to higher
interest-bearing liability levels. The yield on earning assets rose 39 basis
points, to 7.58% from 7.19%, while the average rated paid increased 72 basis
points, from 3.88% to 4.60% with both increases resulting from a higher interest
rate environment.


Other operating income

Other operating income, including the results of investment securities
transactions, was relatively unchanged in the second quarter of 2000 compared to
the similar 1999 period, while such income declined 4.3% during the six months
ended June 30, 2000.compared to the 1999 first half, due primarily to the
receipt in 1999 of $51,000 from the U.S. Department of Treasury, under its Bank
Enterprise Award Program. This program provides financial incentives to banks
making qualifying loans in distressed communities. No such income was received
in 2000.

Other operating expenses

Other operating expenses rose 15% for the second quarter of 2000 to $1,464,000
from $1,273,000 in the second quarter of 1999, with the increase attributable
primarily to higher salaries and benefit expenses, along with increased
collection costs. Merit increases, along with staffing increases resulting from
product and branch expansion, contributed to the salary increase, while higher
health insurance costs was the primary cause for the higher benefit expense.
First half 2000 other operating expenses rose 12.1%, to $2,861,000 from
$2,552,000 a year earlier for the same reasons that caused the second quarter
increase, as well as from higher legal fees incurred in the first quarter of
2000 compared with the same quarter in 1999

Income tax expense

Income tax expense rose in the second quarter of 2000 from the similar 1999
quarter due to higher taxable income levels, while income tax expense as a
percentage of pretax income declined to 31.6% from 37.4% as a result of
increased tax-exempt income. Income tax expense for the first half of 2000
decreased from prior year levels due to lower taxable income levels, while
income tax expense as a percentage of pretax income decreased due to higher
tax-exempt interest income.

LIQUIDITY

The liquidity position of the Corporation is dependent on the successful
management of its assets and liabilities so as to meet the needs of both deposit
and credit customers. Liquidity needs arise primarily to accommodate possible
deposit outflows and to meet borrowers' requests for loans. Such needs can be



                                       11
<PAGE>   12

satisfied by investment and loan maturities and payments, along with the ability
to raise short-term funds from external sources.

It is the responsibility of the Asset/Liability Management Committee ("ALCO") to
monitor and oversee all activities relating to liquidity management and the
protection of net interest income from fluctuations in interest rates.

The Bank depends primarily on deposits as a source of funds and also provides
for a portion of its funding needs through short-term borrowings, such as
Federal Funds purchased, securities sold under repurchase agreements and
borrowings under the U.S. Treasury tax and loan note option program. The Bank
also utilizes the Federal Home Loan Bank for longer-term funding purposes.

The major contribution during the first half of 2000 from operating activities
to the Corporation's liquidity came from proceeds from sales of loans held for
sale, while the highest use of cash was for other assets.

Net cash used in investing activities was primarily for loan originations, while
sources of cash provided by investing activities were derived primarily from
proceeds from maturities, principal payments and early redemptions of investment
securities held to maturity.

The primary source of funds from financing activities resulted from an increase
in deposits, while the highest use of cash in financing activities resulted from
early redemptions of callable long-term debt.

Item 3

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Due to the nature of the Corporation's business, market risk consists primarily
of its exposure to interest rate risk. Interest rate risk is the impact that
changes in interest rates have on earnings. The principal objective in managing
interest rate risk. Interest rate risk is to maximize net interest income within
the acceptable levels of risk that have been established by policy. There are
various strategies which may be used to reduce interest rate risk, including the
administration of liability costs, the reinvestment of asset maturities and the
use of off-balance sheet financial instruments. The Corporation has no risk
associated with off balance-sheet financial instruments.

Interest rate risk is monitored through the use of simulation modeling
techniques, which apply alternative interest rate scenarios to periodic
forecasts of changes in interest rates, projecting the related impact on net
interest income. The use of simulation modeling assists management in its
continuing efforts to achieve earnings growth in varying interest rate
environments.

Key assumptions in the model include anticipated prepayments on mortgage-related
instruments, contractual cash flows and maturities of all financial instruments,
deposit sensitivity and changes in interest rates.

These assumptions are inherently uncertain, and as a result, these models cannot
precisely estimate the effect that higher or lower rate environments will have
on net interest income. Actual results may differ from simulated projections due
to the timing, magnitude or frequency of interest rate changes, as well as
changes in management's strategies.

Based on the results of the most recent interest simulation model, if interest
rates increased or decreased 100 basis points from current rates in an immediate
and parallel shock, the Corporation would anticipate a decrease of $60,000 in
net interest income and an increase of $31,000 in net interest income,
respectively. The results do not represent a material change from the amounts
previously reported as of December 31, 1999.

ITEM 1. LEGAL PROCEEDINGS

In May of 1998, CNB commenced a lawsuit against an entity that acted as an agent
for CNB in the sale of CNB's money orders, and certain affiliates of such entity
for fraud and other damages. CNB alleges, among other things, that at various
times during its business relationship with the defendants, the defendants
stole, misappropriated, hypothecated or embezzled a sum of approximately
$805,000 from CNB. The defendants have responded alleging CNB records regarding
these transactions are in error and that CNB is liable to the defendants for
amounts due as a result of these errors and for damages incurred by the
defendants as a result of CNB's collection efforts. The amount of the
defendants' counterclaim has not been quantified. CNB has filed appropriate
proofs of loss under various insurance policies, including CNB's fidelity bond.
This litigation is currently in the midst of discovery. The likelihood of CNB's
success in this litigation and its ability to recover any amount for which it
obtains judgment is uncertain.
