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


FINANCIAL CONDITION

People's Community Bank (the "Bank") represents virtually all of the assets of
PCB Bancorp, Inc. (the "Company"). The Company's consolidated results of
operations are dependent primarily on net interest income, which is the
difference between the interest income earned on interest-earning assets, such
as loans and investments, and the interest expense incurred on interest-bearing
liabilities, such as deposits and other borrowings. The Bank, which was opened
December 15, 1995, has continued to experience growth during the third quarter
of 1998. Total assets have grown $5.3 million since June 30, 1998, and $16.2
million or 23.5% since December 31, 1997. Growth in total assets was funded by
an increase in deposits of $4.8 million or 6.7% since June 30, 1998 and $15.6
million or 25.7% since December 31, 1997. This growth and anticipated future
growth will allow the Bank to satisfy its cash requirements.

Loans have increased $347 thousand or .55% since June 30, 1998 and $5.8 million
or 9.95% since December 31, 1998. Investment securities have increased $2.3
million or 38.3% since June 30, 1998 and $4.3 million or 103.2% since December
31, 1998.

NONPERFORMING ASSETS AND RISK ELEMENTS. The Bank had nonperforming assets of
$122,000 at September 30, 1998. Diversification within the loan portfolio is an
important means of reducing inherent lending risks. At September 30, 1998, the
Bank had no concentrations of ten percent or more of total loans in any single
industry nor any geographical area outside of the immediate market area of the
Bank.

The Bank discontinues the accrual of interest on loans which become ninety days
past due (principal and/or interest), unless the loans are adequately secured
and in the process of collection. Other real estate owned is carried at fair
value, determined by an appraisal. A loan is classified as a restructured loan
when the interest rate is materially reduced or the term is extended beyond the
original maturity date because of the inability of the borrower to service the
debt under the original terms. The Bank has no restructured loans or other real
estate at September 30, 1998.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity is adequate with cash and due from banks of $3.0 million and federal
funds sold of $6.28 million as of September 30, 1998. In addition, loans and
investing securities repricing or maturing in one year or less exceed $26.8
million at September 30, 1998. The Bank has approximately $5.9 million in
unfunded loan commitments. It is not known how much of this will be funded
within the next six months. Other commitments, primarily stand-by letters of
credit, are approximately $360,000 at September 30, 1998. In order to
collateralize public unit deposits as required by the State of Tennessee
Collateral Pool Board, the Bank has an advance of $1.35 million on a $2 million
line of credit with the Federal Home Loan Bank of Cincinnati at September 30,
1998. The Bank has established a federal fund line of credit with a
correspondent bank totaling $2 million to meet unexpected liquidity demands.
With the exception of unfunded loan commitments, there are no known trends or
any known commitments or uncertainties that will result in the Bank's liquidity
increasing or decreasing in a material way. In addition, the Company is not
aware of any recommendations by any regulatory authorities which would have a
material effect on the company's liquidity, capital resources, or results of
operations.

Total equity capital at September 30, 1998 is $8.27 million or 9.72% of total
assets. The Bank's capital position is adequate to meet the minimum capital
requirements as of September 30, 1998 for all regulatory agencies. The Bank's
capital ratios as of September 30, 1998, are as follows:

                   Tier 1 capital:                     9.59%

                   Total risk-based capital:          10.53%

RESULTS OF OPERATIONS

The company had net income of $156,000 in the third quarter of 1998 compared to
net income of $94,000 in the second quarter of 1997. Net interest income was up
$165,000 or 26.1% over the third quarter of 1998 compared to 1997.

Interest income and interest expense both increased from 1997 to 1998 because
of the increase in earning assets and deposits from September 30, 1997 to
September 30, 1998. The growth in non-interest income for the third quarter of
1998 reflects the increase in deposits during 1997 and 1998.

The provision for loan losses was $11,000 in the third quarter of 1998 compared
to $54,000 in the third quarter of 1997. The allowance for loan losses of
$800,000 at September 30, 1998 (approximately 1.25% of total loans) is
considered adequate to cover losses inherent in the loan portfolio. Management
evaluates the adequacy of the allowance for loan losses monthly and makes
provisions for loan losses based on this evaluation.

YEAR 2000 REPORT

People's Community Bank, like all other banks and financial institutions, is
currently in the process of addressing the Year 2000. The issue arises from the
fact that many existing computer programs use only a two-digit field to
identify the year. These programs were designed without considering the impact
once the calendar year rolls over to "00". If not corrected computer
applications could fail or create inaccurate results by or at the Year 2000.
Because we rely on computer systems, we are placing great emphasis on accessing
our Year 2000 risk, correcting any Year 2000 problems, and providing ample time
to adequately test our systems for Year 2000 readiness. The main phases
involved in the Year 2000 project are assessment, renovation, validation, and
implementation. A comprehensive review to assess the systems affected by this
issue has been completed, estimated cost projections have been determined and
an implementation plan has been compiled. Our Management and Board of Directors
are involved in our business strategy. We're working with our regulators to
ensure that we take into consideration all pertinent guidance on Year 2000
issues and stay within the timelines established for dealing with Year 2000
issues. We're also working with outside vendors to verify that their systems
will be ready. People's Community Bank must not only evaluate and test its own
Year 2000 readiness, it must also coordinate with other entities with which it
routinely interacts such as suppliers, creditors, borrowers, customers, and
other financial service organizations. Regulations require People's Community
Bank to accomplish specific Year 2000 actions by specific dates.

People's Community Bank has initiated an implementation plan providing for Year
2000 readiness by the end of 1998. Management believes the plan is on target
with the goals established by its regulators. We have completed the awareness
and assessment phases and have substantially completed the remediation phase of
the plan. People's data processing software has been updated to ensure Year
2000 compliance. The Bank has substantially completed the testing phase of our
implementation plan, with completion scheduled for year-end 1998. A contingency
plan for Year 2000



                                       8

is in the development process to address mission critical systems. Our
contingency plans will be adapted to include such items as utilization of our
back-up data processing site, business resumption plans, identifying
alternative sources of liquidity, and evaluating alternative manual processes.
The adaptation and testing of these contingency plans should be finalized early
in 1999.

People's Community Bank has determined that the Year 2000 issue may be critical
to its operations; however, Management does not believe customer readiness is
or will be material to its overall performance. Management also believes that
the total costs of becoming Year 2000 compliant will not be significant.
Through 1997, expenditures for Year 2000 were immaterial, and as of this date,
Year 2000 related expenditures for 1998 are projected to be approximately
$10,000.00.
