             Callidus Software Reports Third Quarter 2004 Results

                          Q3 Revenues $13.9 Million

    SAN JOSE, Calif., Oct. 27 /PRNewswire-FirstCall/ -- Callidus Software Inc.
(Nasdaq: CALD), a leader in Enterprise Incentive Management (EIM), today
announced financial results for the third quarter ended September 30, 2004.
    Total third quarter revenues were $13.9 million, an increase of 5%
compared to prior quarter revenues of $13.2 million, and a decrease of 29%
compared to third quarter 2003 revenues of $19.7 million. Third quarter net
loss was $4.3 million, or ($0.18) per share, compared to a net loss of $13.7
million, or ($0.57) per share for the prior quarter and break-even for the
third quarter of 2003.
    Non-GAAP net loss for the third quarter was $2.4 million, or ($0.10) per
share, as compared to non-GAAP net loss of $5.7 million, or ($0.24) per share
in the prior quarter and non-GAAP net income of $1.4 million, or $0.06 per
share in the third quarter of 2003.  A reconciliation between GAAP and
non-GAAP information is contained in the attached tables.
    "Maintenance and service revenues and associated gross margin amounts
exceeded our targets for the third quarter.  Operating expenses, excluding
restructuring charges and stock-based compensation, were also better than we
had targeted for the quarter.  While third quarter license revenues improved
incrementally from the prior quarter, the Company's focus in the near term
continues to be on sales execution efforts and achieving continued incremental
growth in license revenues," said David Pratt, president and CEO of Callidus
Software.
    In the third quarter, Callidus recorded restructuring expenses of
$1.5 million and substantially completed the cost savings actions announced
earlier in the quarter.  The restructuring expenses comprised workforce
reduction costs and charges for asset impairments.  None of the restructuring
actions impacted the development or customer support areas of the TrueComp
product suite.
    During the third quarter Callidus held its largest annual users'
conference, with representatives from 82 companies and eight partner
organizations.  Customers and partners presenting at the conference included
Accenture, IBM, Deloitte Consulting, CUNA Mutual, Novell, AT&T Wireless,
Citizens Bank and DIRECTV.
    Also in the third quarter, Callidus announced that Steve Apfelberg joined
Callidus as vice president of product marketing.  Prior to joining Callidus,
Apfelberg was a senior director of product marketing at Siebel, where he
managed all aspects of the company's EIM initiatives, including the
development, marketing, and sales of Siebel's Incentive Compensation
Management solution.
