            Callidus Software Reports Second Quarter 2004 Results

              Q2 Revenues $13.2 Million; Reducing Cost Structure

    SAN JOSE, Calif., July 21 /PRNewswire-FirstCall/ -- Callidus Software Inc.
(Nasdaq: CALD), a leader in Enterprise Incentive Management (EIM), today
announced financial results for the second quarter ended June 30, 2004.
    Total second quarter revenues declined 20% to $13.2 million compared to
$16.6 million in the second quarter of 2003. Second quarter net loss was $13.6
million, or ($0.56) per share, compared to net income of $0.5 million, or
$0.03 per share, for the second quarter of 2003.
    Non-GAAP net loss for the second quarter was $5.6 million, or ($0.23) per
share, as compared to non-GAAP net income of $0.8 million, or $0.04 per share
in the second quarter of 2003.  A reconciliation between GAAP and non-GAAP
information is contained in the attached tables.
    "Second quarter maintenance and service revenues met our expectations;
however, product revenues were substantially below our initial expectations
for the quarter.  We continued to experience longer selling cycles and delays
in closing transactions during the quarter," said David Pratt, president and
CEO of Callidus Software.
    "During my short tenure, I have worked closely with the executive team and
met with many of our employees, customers, prospective customers and partners.
My assessment is that Callidus has great products, happy customers, strong
partnerships and a good employee base.  Our focus in the near term will be on
sales execution efforts and on reducing our cost structure to lower our break-
even point," continued Pratt.
    Callidus also announced the discontinuance of its TruePerformance product.
In connection with this decision, Callidus recorded impairment charges
totaling $3.8 million on intangible assets in the second quarter.
    "We believe the TrueComp(R) suite of products has greater return on
investment potential than the TruePerformance product.  Accordingly, the
discontinued investment in TruePerformance will result in quarterly cost
savings of approximately $800,000, excluding related shut down costs, while
not negatively impacting anticipated 2004 revenues," said Pratt.  The TrueComp
suite, including TrueResolution(TM), TrueReferral(TM), and
TrueInformation(TM), has constituted the vast majority of product revenues
since the inception of Callidus.
    In addition to discontinuing TruePerformance, Callidus expects to
implement other cost savings actions and closely monitor discretionary
spending.  These actions are anticipated to result in additional quarterly
cost savings of approximately $1.2 million.  The impact of the combined cost
savings actions will be partially realized in the third quarter.  Accordingly,
management anticipates operating expenses for the third quarter of 2004,
excluding stock-based compensation and charges related to the cost savings
actions, to be between $9.5 million and $10.5 million.
    Maintenance and service revenues for the third quarter are expected to be
between $10.0 million and $11.0 million with a contributing margin of 28% to
30%.

    Q2 2004 Financial Summary

     *    License revenues were $1.9 million, declining 79% year-over-year.
     *    Maintenance and service revenues were $11.3 million; increasing 46%
          year-over-year.  Excluding an accrual for a TruePerformance related
          claim, maintenance and service revenues were $12.1 million;
          increasing 56% year-over-year.
     *    Operating expenses were $16.7 million.  Excluding stock-based
          compensation, amortization and impairment of intangibles and legal
          settlements, operating expenses were $11.4 million in Q2 2004, an
          increase of $2.4 million from Q2 2003.  The increase is the result
          of added investments in all areas of the business and the costs of
          being a public company.
     *    Cash and investments totaled $70.0 million on June 30, 2004.
     *    Days Sales Outstanding (DSO) in accounts receivable at the end of
          the quarter was 66 days, unchanged from the end of the first quarter
          of 2004.
