           CFS Bancorp, Inc. Announces First Quarter Results

MUNSTER, IN - April 28, 2003 - CFS Bancorp, Inc. (NASDAQ: CITZ)
(Company), the parent holding company for Citizens Financial Services,
FSB (Bank), today reported first quarter net income of $654,000 or
$0.06 per share.  This compares to net income for the first quarter of
2002 of $1.6 million or $0.12 per share.

     Net interest income for the first quarter of 2003 was $6.8
million compared to $8.0 million reported for the same period in 2002.
This decrease in net interest income reflects the compression of
interest rate spreads and net interest margins between the first
quarter of 2002 and the first quarter of 2003 reflecting in large part
the effects of the declining interest rate environment experienced
during the past two years.  Also contributing to the decrease in net
interest income, when comparing the first quarter of 2003 to the first
quarter of 2002, was the acceleration of prepayments of mortgage loans
underlying mortgage-backed securities.  Many of these securities were
purchased at a premium to par.  These premiums were amortized against
income based on an assumed level yield.  As prepayments and repayments
of the underlying mortgages accelerated, the rate of amortization of
these premiums was accelerated, resulting in approximately $550,000 of
additional premiums being amortized against income over and above
scheduled amounts during the first quarter of 2003.

     The Company's interest income was $18.6 million and $22.0 million
for the three months ended March 31, 2003 and 2002, respectively.  The
average balances of both loans receivable and securities increased
while the average balance of other interest-earning assets decreased
when comparing the first quarter of 2003 to the first quarter of 2002.
Increased interest income resulting from the increases in average
balances was more than offset by the reduction in average yields on
all interest-earning categories in the first quarter of 2003 when
compared to the first quarter of 2002.

     Interest expense was $11.8 million and $14.0 million for the
three months ended March 31, 2003 and 2002, respectively.  Average
balances of checking and savings accounts increased during the three
months ended March 31, 2003 compared to the three months ended March
31, 2002, while the average balances of certificates of deposit and
borrowings decreased when comparing these same periods.  The resultant
net increase in average balances was more than offset by the reduction
in average costs paid on all interest-bearing liabilities during the
first quarter of 2003 when compared to the first quarter of 2002.

     The Company's provision for loan losses for the three months
ended March 31, 2003 was $478,000 compared to $200,000 for the same
period in 2002.  The Company continued to increase its allowance for
losses on loans as a percentage of total loans.  The Company believes
this to be prudent based on the present economy and the Company's
strategy of increasing the ratio of multi-family and commercial real
estate mortgage loans and commercial loans to total loans.  Included
in the 2003 provision is $28,000 relating to overdrafts of deposit
products from a new program which began in the third quarter of 2002.

     Non-interest income for the three months ended March 31, 2002 was
$2.3 million compared to $2.2 million for the same period in 2002.
There was no income from insurance commissions during the first
quarter of 2003 compared to $288,000 during the first quarter of 2002
as a result of the sale of the insurance agency's assets during the
fourth quarter of 2002.  Income from investment commissions was
$126,000 during the three months ended March 31, 2003 compared to
$262,000 for the three months ended March 31, 2002.  This change
reflects the Company's decision to outsource the sale of non-deposit
products beginning in August 2002.  Although the commission income
during the first quarter of 2003 was less than 2002, due to changing
operations in the area of non-deposit products, the Company was able
to eliminate most expenses related to insurance and investment
commissions.  Non-interest expense related to insurance commissions in
the three months ended March 31, 2003 was $0 compared to $321,000 for
the three months ended March 31, 2002.  Non-interest expense for the
three months ended March 31, 2003 pertaining to investment commissions
was $13,000 compared to $267,000 for the same period in 2002.  There
were no gains on the sale of investment securities during the first
quarter of 2003 compared to $247,000 during the first quarter of 2002.
These reductions of income during the first quarter of 2003 when
compared to the first quarter of 2002 were offset by increased fees on
deposit accounts.  Income from these fees during the three months
ended March 31, 2003 was $1.1 million compared to $538,000 for the
three months ended March 31, 2002.

     Non-interest expense for the three months ended March 31, 2003
was $7.6 million compared to $7.8 million for the same period in 2002.
Compensation and employee benefits were $4.4 million for the first
quarter of 2003 compared to $5.0 million for the same period in 2002.
The primary reason for the reduction in compensation and benefit
expense was the efficiency realized by the Company upon the
restructuring of its non-depository product functions as described in
the preceding paragraph.  This reduction was partially offset by
increases in other areas.

     Income tax expense was $313,000 for the three months ended March
31, 2003 compared to $661,000 for the same period in 2002.  This
decrease is primarily due to reduced income in the first quarter of
2003 compared to the first quarter of 2002.  The effective tax rate
for all of 2003 is expected to approximate that of 2002.

     Chairman Thomas F. Prisby stated, "The current rate environment
continues to have a significant effect on our earnings.  As rates
rebound, we expect net interest income and most other financial ratios
to improve; we also anticipate we will then reap the benefits of our
current investment and lending strategies.

     "High levels of liquidity and high-rate Federal Home Loan Bank
borrowings continue to have the greatest negative impact on current
earnings.  We will continue our efforts to improve the asset
composition with additional investments in quality loans and
securities.  As residential loan repayments continue to slow from the
35% level of 2002 and the first quarter of 2003, excess liquidity is
expected to be absorbed through normal operations."
