                SPSS CFO HAMBURG TO RETIRE, PANZA NAMED SUCCESSOR

CHICAGO, Ill. (USA), August 11, 2004 -- SPSS Inc. (NASDAQ: SPSS), a global
provider of predictive analytics technology and services, today announced the
retirement of Edward Hamburg, long-time company executive and its chief
financial officer since 1993. He will be replaced on August 16, 2004, by Raymond
Panza, a senior financial executive with over thirty years of financial
management experience.

"Simply put, a different skill set is required to help take this company to the
next level," said Hamburg, who will remain a full-time member of the SPSS
executive committee through the end of 2004 and then maintain his 16-b affiliate
status for at least another twelve months. "The next generation of challenges
and opportunities for SPSS will best be met by a CFO with clear strengths in
process management and more extensive experience in leading complex financial
operations. Ray possesses these attributes and is the right fit for the
company."

"Ed is both a colleague and friend," said Jack Noonan, SPSS president and chief
executive officer. "He has been a consistent source of leadership, guidance and
strength as we built SPSS from a $25 million provider of statistical products
into a $200 million enterprise software company."

Noonan continued, "We are most fortunate, however, to have an extremely
qualified executive in Ray Panza to fill this role. SPSS will benefit
substantially from his broad financial experience and history of performance at
major public companies."

Panza was most recently Vice President, Finance at Thomson (NYSE: TMS), where he
was responsible for mergers and acquisitions, financing activities and financial
reporting. He played a leadership role in the company's acquisition of
Technicolor and its launch of several successful new businesses. Panza also
served as project manager for Thomson's joint venture in China, resulting in
creating the world's largest television manufacturing and distribution
capability. He previously held senior financial roles at Ameritech (NYSE: SBC),
DQE (NYSE: DQE), Squibb (NYSE: BMY), RKO General and Gulf Oil Corporation. Panza
is a certified public accountant with graduate and undergraduate degrees from
The Pennsylvania State University.

"I am looking forward to working with Jack and the SPSS leadership team as we
build on the company's established advantage in the predictive analytics
market," said Panza. "I appreciate the opportunity to use my experience and
talents in helping SPSS realize its potential and create increasing value for
all stakeholders."

Noonan concluded, "This transition process began in December 2003. We had
reached the point where our accounting processes were much improved, the balance
sheet strengthened and the finance organization stronger than at any time in the
company's history. With this foundation in place, a nationwide search began in
February 2004. The search continued through our recent accounting review and
restatement, which Ed and his team admirably brought to completion. Ray is now
joining an organization with a clean bill of health that is well positioned to
take the next steps towards its strategic and operational goals."
