    SAN JOSE, Calif., June 24 /PRNewswire-FirstCall/ -- Callidus Software Inc.
(Nasdaq: CALD), a leader in Enterprise Incentive Management (EIM), today
announced the appointment of David Pratt as interim president and chief
executive officer. Mr. Pratt replaces Reed Taussig who has resigned as
president, chief executive officer and chairman of the board.
    Callidus Software also announced today that anticipated second quarter and
full year results will not meet guidance as previously provided in April 2004.
Guidance is not being updated. The Company currently plans to announce second
quarter results on July 21, 2004.
    Mr. Pratt, a software industry veteran with 35 years of senior management
and operational expertise, was appointed to the Callidus board of directors
earlier this month. Mr. Pratt, previously COO of Adobe, was instrumental in
growing Adobe's revenue from $50 million to $1 billion during his 10 year
tenure. Most recently, Mr. Pratt was CEO of AvantGo, Inc., a provider of
mobile enterprise software, and prior to that, served as CEO of gForce Systems
and FlashPoint. In addition, he served as COO of Logitech and Quantum.
    "Callidus Software is a leader in the very exciting EIM market providing
systems to global companies across multiple industries. I am looking forward
to working with the Company's excellent and dedicated management team," Pratt
said.
    Callidus Software also announced the appointment of Michael Braun as
chairman of the board of directors. Mr. Braun, a retired IBM executive, has
served as a board member of Callidus since February 2000. Mr. Braun previously
served as CEO of Blaze Software and Kaleida Labs and currently serves as the
chief executive officer of the Interim CEO Network.
    "We are fortunate to have an executive of David Pratt's experience and
stature to lead Callidus forward at this time and we are optimistic about the
future," said Mr. Braun.
    "Reed's leadership over the past seven years has been crucial as the
company has grown from a small start-up to a publicly traded company," Braun
said. "Through his leadership Callidus became a leader in the EIM market and
today lists many well-respected and satisfied blue chip companies as its
customers. Together, Reed and the Board decided that it was time for new CEO
at Callidus and we wish him well."
    "I am proud of what the team has accomplished at Callidus in the past
seven years and I remain confident in Callidus' technological advantage and
leadership position in the EIM market," said Mr. Taussig.
