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 first quarter
of 2000. Total assets have grown $4.3 million or 4.2% since December 31, 1999.

Loans have increased $4.0 million or 5.6% since December 31, 1999. Investment
securities have increased $96 thousand or 0.5% since December 31, 1999.

NONPERFORMING ASSETS AND RISK ELEMENTS. The Bank had $317,000 in nonperforming
assets at March 31, 2000. Diversification within the loan profile is an
important means of reducing inherent lending risks. At March 31, 2000, the Bank
had no concentrations of ten percent or more of total loans in any single
industry nor any geographical area outside the immediate market area of the
Bank. At the present time, the Bank has impaired loans totaling $293,000. In
reference to the impaired loans, the Bank has related allowance for credit
losses totaling $167 thousand, leaving a balance classified as substandard of
$126 thousand. The Bank also currently has $124 thousand in other real estate
owned.

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.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity is adequate with cash and due from banks of $5.4 million as of March
31, 2000. In addition, loans and investment securities repricing or maturing in
one year or less exceed $30.8 million at March 31, 2000. The Bank has
approximately $6.56 million in unfunded loan commitments. It is not known how
much of this will be funded within the next six months. Other commitments,
primarily, standby letters of credit, are approximately $724,000 at March 31,
2000. The Bank has outside funding sources including fed fund lines of credit,
cash management accounts, and security repurchase agreements with the Federal
Home Loan Bank, AmSouth Bank and Columbus Bank and Trust of Georgia. The amount
of funding available through these agreements totaled $14.5 million with $8.5
million having been drawn as of March 31, 2000. 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 March 31, 2000, is $8.6 million or 8.0% of total assets. The Bank's
capital position is adequate to meet the minimum capital requirements as of
March 31, 2000 for all regulatory agencies. The Bank's capital ratios as of
March 31, 2000, are as follows:

                  Tier 1 capital                              11.5%

                  Tier 2 capital                               1.1%

                  Total risk-based                            12.6%

RESULTS OF OPERATIONS

The Company had net income of $202,000 in the first quarter of 2000 compared to
income of $144,000 in the first quarter of 1999. Net interest income was up
$120,000 or 14.7% over the first quarter of 2000 compared to 1999.

Interest income and interest expense both increased from 1999 to 2000 because of
the increase in earning assets and funding sources (i.e. deposits and
borrowings) from March 31, 1999 to March 31, 2000.

The provision for loan losses was $49,000 in the first quarter of 2000 compared
to $19,000 in the first quarter of 1999. The allowance for loan losses of
$905,000 at March 31, 2000 (approximately 1.21% of 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
loan losses based on this evaluation.
