               CFS Bancorp, Inc. Announces Third Quarter Results

     MUNSTER, IN - October 23, 2003 - CFS Bancorp, Inc. (NASDAQ: CITZ)
(the "Company"), the parent holding company Citizens Financial Services, FSB
(the "Bank"), today reported third quarter net income of $967,000 or $0.08 per
diluted share.  Year to date net income for 2003 totaled $2.3 million or $0.20
per diluted share.  This compares to net income of $1.8 million or $0.15 per
diluted share for the third quarter of 2002 and net income of $5.4 million or
$0.43 per diluted share for the nine months ended September 30, 2002.


     Net interest income for the third quarter of 2003 was $6.7 million
compared to $8.8 million reported for the third quarter of 2002.  Net interest
income for the first nine months of 2003 was $19.9 million compared to $25.9
million for the same period in 2002.  During the third quarter of 2002, the
Company opened two new offices.  These offices, opened in early July 2002,
offered an above-market rate 90-day certificate.  This offer was available for
a 60-day period and resulted in approximately $80.0 million in new deposits.
This promotion had an effect on both interest income and interest expense and
in the short term reduced interest rate spreads and margins.

     Interest income for the third quarter of 2003 was $17.0 million compared
to $22.0 million for the third quarter of Interest income for the first nine
months of 2003 was $53.3 million compared to $66.2 million for the first nine
months of 2002.  The primary reason for the decreases in the 2003 periods was
the significant decline in the average yields earned on interest-earning assets
in 2003 as compared to 2002 reflecting the effect of the low-rate interest
environment existing throughout 2003.  Increases in average balances of total
loans outstanding during the 2003 periods as compared to the 2002 periods
partially offset the decline in average yields.  Decreases in the average
balances of securities and other interest-earning assets added to the decline
in interest income in both the three and nine months ended September 30, 2003
when compared to the same periods in 2002.

     Interest expense for the three months ended September 30, 2003 was $10.3
million compared to $13.3 million for the same period in 2002.  Interest
expense for the nine months ended September 30, 2003 was $33.4 million compared
to $40.3 million for the nine months ended September 30, 2002.  The decrease
in interest expense for the three and nine months ended September 30, 2003
when compared to the 2002 periods was primarily the result of a decrease in the
average cost of deposits.  Also during these same periods the average balance
of borrowed money decreased.  The average balance of deposits decreased when
comparing the three months ended September 30, 2003 to the three months ended
September 30, 2002, reflecting a partial reduction in the deposits obtained in
the previously mentioned special promotion in the third quarter of 2002.
Average balances of deposits increased modestly when comparing the nine months
ended September 30, 2003 to the nine months ended September 30, 2002.

     The Company's provisions for loan losses for the three months ended
September 30, 2003 and 2002 were relatively stable, amounting to $502,000 and
$500,000, respectively, while the provisions for the nine months ended
September 30, 2003 and 2002 were $1.5 million and $1.1 million, respectively.
In light of the Company's emphasis on increasing its commercial real estate
and business lending and the increased estimate of the amount of known and
inherent losses in the loan portfolio, the Company continues to increase its
allowance.

     Non-interest income for the three months ended September 30, 2003 was
$3.0 million compared to $2.6 million for the three months ended September 30,
2002 and amounted to $7.9 million for nine months ended September 30, 2003
compared to $7.4 million for the same period in 2002.  The improvement in
non-interest income was primarily the result of increased fees on deposit
accounts in both periods, which were partially offset by reductions in both
insurance and investment commissions due to the sale of the Company's insurance
agency assets in December 2002 and the outsourcing of the sale of investment
products in August 2002.  Non-interest income in the three and nine months
ended September 30, 2003 included net gains on sale securities in the Company's
available-for-sale investment portfolio of $326,000 and $325,000, respectively,
compared to $10,000 and $281,000 for the three and nine months ended September
30, 2002.

     Non-interest expense was $7.8 million for the three months ended September
30, 2003 compared to $8.3 million for the three months ended September 30, 2002.
Non-interest expense was $23.1 million for the first nine months of 2003
compared to $24.6 million for the same period in 2002.  For both the three and
nine months ended September 30, 2003,compared to the same periods in 2002,
decreases resulted primarily from decreases in compensation and employee
benefits due to reductions in overhead and compensation expense as a result of
the Company's outsourcing of the sale of investment products and the sale of
the insurance agency's assets, previously described.

     Income tax expense for the three months ended September 30, 2003 was
$315,000 or 24.5 percent of income before income taxes compared to $755,000 or
29.4 percent of income before income taxes for the three months ended September
30, 2002.  For the nine months ended September 30, 2003, income tax expense was
$886,000 or 27.6 percent of income before income taxes compared to $2.3 million
or 29.8 percent for the same period in 2002.  The Company estimates that its
effective rate for the remainder of 2003 will be approximately 25.0 percent.

     Chairman and CFO Thomas F. Prisby stated, "There are several positive
items to mention as we enter the fourth quarter of 2003.  Mortgage refinancing
activity has dropped significantly from record highs.  As a result, prepayments
have started to decline and should continue to do so in the fourth quarter of
2003.  With these slower prepayments we expect premium amortization on
investments in the fourth quarter to be reduced markedly from the first three
quarters of 2003.  On the liability side, some of our higher costing borrowings
were repaid at the end of the quarter.  Taken together, we expect improvements
in net interest income in future periods.

     "In addition, CFS continues to make strides in operational improvements,
controlling operating expenses and increasing non-interest income. Also, in the
third quarter we opened a new office in Naperville and completed a branch
purchase in Bolingbrook thereby increasing our footprint in the Illinois
market.  We believe these actions coupled with our improving outlook for net
interest income will lead to enhanced earnings and increased shareholder
value."
