              Callidus Software Reports First Quarter 2004 Results

                       Q1 Revenues Up 25%, Year over Year

    SAN JOSE, Calif., April 21 /PRNewswire-FirstCall/ -- Callidus Software
Inc. (Nasdaq: CALD), the leader in Enterprise Incentive Management (EIM)
software systems, today announced financial results for the first quarter
ended March 31, 2004 consistent with its revised outlook provided on March 29,
2004.
    Total first quarter revenues grew 25% to $16.5 million compared to $13.1
million in the first quarter of 2003. First quarter net loss was $6.1 million,
or ($0.25) per share, compared to a net loss of $0.4 million, or ($0.26) per
share, for the first quarter of 2003.
    Non-GAAP net loss for the first quarter was $4.3 million, or $0.18 per
share, as compared to non-GAAP net income of $0.6 million, or $0.03 per share
in the first quarter of 2003.  A reconciliation between GAAP and non-GAAP
information is contained in the attached tables.
    "Maintenance and service revenues were up year-over-year; however, product
revenues were significantly below our initial expectations for the quarter.
Callidus' financial results are dependent on a relatively small number of
large software license transactions that often close at the end of a quarter.
In this quarter, we failed to close several transactions due to customers'
merger and acquisition activities. In addition, a number of customers did not
conclude contracts for their own internal reasons which resulted in a
shortfall of our license revenues and negatively impacted our bottom line,"
said Reed Taussig, president and CEO of Callidus Software.
    "We believe that our prospective customers remain committed to Callidus
and that many will join our list of top quality customers, which includes:
AT&T Wireless, BMC Software, CUNA Mutual Insurance, JP Morgan Chase & Co. and
SBC Communications.  We remain enthusiastic about our prospects, given the
emerging opportunity of the EIM market, our strong product position and our
dedication to customer satisfaction," continued Taussig.

    Q1 2004 Financial Summary

    -- License revenues were $4.5 million, declining 41% year-over-year.
    -- Maintenance and service revenues were $11.9 million; increasing 120%
       year-over-year.
    -- Operating expenses, excluding stock-based compensation, were $12.1
       million in Q1 2004, an increase of $4.5 million from Q1 2003.  The
       increase is the result of continued investment in all areas of the
       business to drive future growth and meet the needs of a public company.
    -- Operating cash flow for the quarter was approximately breakeven.  Cash
       and investments totaled $79.3 million on March 31, 2004.
