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 1999. Total assets have grown $12.77 million or 13.94% since December 31,
1998, and $10 million or 10.60% since June 30, 1999. During the period January
1, 1999 to September 30, 1999, the growth in total assets has been funded by
increases in deposits of $13.66 million or 16.7% growth. This growth, and
anticipated future growth, will allow the Bank to satisfy its cash requirements.
It is not anticipated that it will be necessary to raise any additional funds.

Loans have increased $2.5 million or 3.76% since December 31, 1998. The loan
portfolio, however, has grown $ 2.52 million or 3.76% since June 30, 1999.
Investment securities have increased $6.06 million or 47.89% since December 31,
1998. Investment securities have increased $2.86 million or 18.02% since June
30, 1999.

NONPERFORMING ASSETS AND RISK ELEMENTS. The Bank had $306,000 in nonperforming
assets at September 30, 1999. Diversification within the loan portfolio is an
important means of reducing inherent lending risks. At September 30, 1999, the
Bank had no concentrations of ten percent or more in total loans in any single
industry or 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 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 had other real estate owned of $188,000 at
September 30, 1999.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity is adequate with cash and due from banks of $3.52 million and federal
funds sold of $9.1 million as of September 30, 1999. In addition, loans and
investment securities repricing or maturing in one year or less exceed $29.6
million at September 30, 1999. The Bank has approximately $7.74 million in
unfunded loan commitments. It is not known how much of this will be funded
within the next six months. Other commitments, primarily financial standby
letters of credit, are approximately $1.2 million at September 30, 1999.

With the exception of unfunded loan commitments, there are no known trends or
uncertainties that will result in the Bank's liquidity increasing or decreasing
in a material way. The Bank has secured additional sources of funds, above and
beyond those supplied


                                       7

through the normal course of business, should liquidity needs arise. The Bank
has established a federal funds line of credit with its correspondent bank,
First American National Bank, totaling $2.5 million. An additional $2.5 million
Securities Repurchase Agreement has also been arranged between the Bank and
First American National Bank. As a benefit of its Federal Home Loan Bank
membership, the Bank has a $2 million standby letter of credit, with $1.5
million of the line currently pledged toward the State of Tennessee Collateral
Pool Board for the securing of public funds held on deposit. The Bank has
received approval from the Federal Home Loan Bank for a special Y2K line of
credit totaling $9 million. A $2.5 million federal funds line of credit has also
been secured through Columbus Bank and Trust in Columbus, Georgia. The Board of
Directors has also authorized the Bank to apply to the Federal Reserve for the
ability to borrow through the Federal Discount Window in Atlanta, Georgia. The
application with the Federal Reserve is pending as of this report date. The
Federal Discount Window allows participants to borrow funds against pledged
assets of the Bank. In addition, the Company is not aware of any adverse
recommendations by bank regulatory agencies, which would have a material impact
on the Company's liquidity, capital resources, or results of operations.

Total equity capital at September 30, 1999 is $8.5 million or 8.1% of total
assets. The Bank's capital position is adequate to meet the minimum capital
requirements as of September 30, 1999 for all regulatory agencies. The Bank's
capital ratios as of September 30, 1999, are as follows:

                <S>                                <C>
                Tier 1                              9.95%

                Total Risk-based capital           10.95%

RESULTS OF OPERATIONS

The Company had net income of $174,000 during the third quarter of 1999 compared
to net income of $156,000 during the third quarter of 1998. For the nine months
ended September 30, 1999, the Company had net income of $509,000, which was a
21.5% increase over the same period in 1998. Net interest income was up $120,000
or 15.1% over the third quarter of 1999 compared to 1998. Net interest income
for the nine month period ended September 30, 1999 increased $286,000 or 12.58%
over the same period in 1998.

Interest income and interest expense both increased from 1998 to 1999 because of
the increase in earning assets and deposits from September 1998 to September
1999. The growth in non-interest income for the period ending September 30, 1999
reflects the increase in deposits during 1998 and 1999.

The provision for loan losses was $34,000 in the third quarter of 1999 compared
to $11,000 in the third quarter of 1998. The allowance for loan losses of
$870,000 at September 30, 1999 (approximately 1.25% of total loans) is
considered to be adequate to cover losses inherent in the loan portfolio.
Management evaluates the adequacy of the allowance for loan losses monthly and
makes provisions for the loan losses based on this evaluation.

YEAR 2000 REPORT

People's Community Bank, like all other banks and financial institutions, is
aware of and taking steps to address the Year 2000 issue. Our Year 2000 strategy
is designed to position us for success for the next millennium. We have reviewed
all areas of Year 2000 risk for our Bank. We formed a Project Team and began
building internal awareness. A Steering Committee comprised of senior management
was organized and a senior officer was appointed as Year 2000 Project
Administrator. The Steering Committee is responsible for evaluating Year 2000
impact on systems, and then testing or verifying that readiness. Our project
methodology conforms to guidelines suggested by the Federal Financial
Institutions Examinations Council. The foundation of our approach involves five
phases: Awareness, Assessment, Renovation, Validation, and Implementation. Our
Year 2000 process and progress are reviewed and evaluated by government
regulators. Testing and analyzing hardware and software is a critical element to
addressing the Year 2000 issue. During the first half of 1999, we substantially
completed the remediation and testing of our critical systems. In addition, we
are actively working with our customers in all areas to ensure the Year 2000
readiness of software, hardware, services, and processes used to conduct
business. The Steering Committee has also prepared a Contingency Plan to address
actions to be taken before, during and after January 1, 2000. We have also
prepared a cash and liquidity plan to prepare for additional cash, which might
be needed to respond to customer requests.

For the remainder of 1999, People's Community Bank will continue to validate
readiness for the Year 2000 date change through further systems tests. Detailed
contingency, cash and liquidity plans will be implemented to ensure a smooth
transition into the new century. We believe that our approach is sound,
comprehensive and positions us to be successful in the Year 2000 and beyond.
