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 1998. Total assets have grown $7.7 million or 11% since December 31, 1997.
During the period January 1, 1998 to March 31, 1998, the growth in total assets
has been funded by increases in deposits of $7.8 million or 13%. This growth and
the 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 $1.7 million or 3% since December 31, 1997. Investment
securities have increased $30 thousand or .71% since December 31, 1997.

NONPERFORMING ASSETS AND RISK ELEMENTS. The Bank had nonperforming assets
totaling $19,220.12 at March 31, 1998. Diversification within the loan profile
is an important means of reducing inherent lending risks. At March 31, 1998, 1-4
Family Residential Loans, (adjustable and construction- with arms of 1, 3, & 5
years), comprised 20.5% of the Bank's total loan portfolio. No other industry or
geographical area outside the Bank's immediate market area were responsible for
at least ten percent of the Bank's loan portfolio at March 31, 1998.

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 had no restructured loans or other real
estate at March 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity is adequate with cash and due from banks of $2.1 million and federal
funds sold of $7.6 million as of March 31, 1998. In addition, loans and
investment securities repricing or maturing in one year or less exceed $25.7
million at March 31, 1998. The Bank has approximately $6.1 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 $350,000 at March 31, 1997. In addition to the Federal Home Loan
Bank membership, 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.



                                       7
<PAGE>   8



Total equity capital at March 31, 1998, is $7.9 million or 10% of total assets.
The Bank's capital position is adequate to meet the minimum capital
requirement's as of March 31, 1998 for all regulatory agencies. The Bank's
capital ratios as of March 31, 1998, are as follows:

                  Tier 1 capital                              10.7%

                  Tier 2 capital                               1.0%

                  Total risk-based                            11.7%

RESULTS OF OPERATIONS

The Company had net income of $127,000 in the first quarter compared to income
of $19,000 in the first quarter of 1997. Net interest income was up $199,000 or
40% over the first 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 March 31, 1997 to March 31,
1998. The growth in non-interest income for the first quarter of 1998 reflects
the increase in deposits during 1997 and 1998.

The provision for loan losses was $33,000 in the first quarter of 1998 compared
to $126,000 in the first quarter of 1997. The allowance for loan losses of
$757,000 at March 31, 1998 (approximately 1.25% 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.
