                 SPSS INC. FURTHER DELAYS FILING 2003 FORM 10-K

CHICAGO, IL. (USA), March 30, 2004 -- SPSS Inc. (NASDAQ: SPSS), a global
provider of predictive analytics technology and services, today announced that
it would further delay the filing of its annual report on Form 10-K with the
United States Securities and Exchange Commission to complete an additional
review initiated by the company.

As reported in its press release of March 15, 2004, SPSS is restating quarterly
and annual results from the fourth quarter 2001 to the fourth quarter 2003 on a
basis consistent with its October 2003 amended agreement with America Online
(AOL). Among the expected effects of this restatement on 2003 results announced
in the SPSS earnings release of February 18, 2004, is a reduction in operating
income from $6.9 million to $2.7 million and goodwill on the December 2003
balance sheet from $49.3 million to $39.3 million. These adjustments, combined
with the results of a separate reexamination and restatement of the provision
for income tax, are expected to reduce reported earnings per share in 2003 from
$0.63 to $0.58. These results, however, remain subject to change pending their
ongoing review by the company's auditors.

While performing this restatement, SPSS discovered an error in its deferred
revenue accounts. The company's preliminary analysis shows that this error:

     o   Does not affect 2003 operating results;

     o   Was related to the company's initial implementation at the end of 2000
         of new accounting interpretations on revenue recognition; and

     o   Caused revenues in GAAP reporting for the effected periods to be
         overstated by between $3.0 and $6.0 million.

Despite the limited scope of the identified error, SPSS elected to thoroughly
review and have its auditors verify all of its deferred revenue accounts before
releasing restated financial statements for 2001 and 2002 as well as its
previously unreleased financial statements for 2003. The company will provide
updates on the timing of these filings as soon as possible.

The restated financial results to be filed do not affect the company's 2004
guidance.
