             Callidus Software Revises Revenue and Earnings Outlook
                           For the First Quarter 2004

    SAN JOSE, Calif., March 29 /PRNewswire-FirstCall/ -- Callidus Software
Inc. (Nasdaq: CALD), the leader in Enterprise Incentive Management (EIM)
software systems, today revised its outlook for the first quarter ending
March 31, 2004.
    The Company expects total revenues for the first quarter of 2004 to be
between $16.5 million and $18.0 million due to a shortfall of license
revenues.  As a result Callidus anticipates a net loss for the quarter on both
a GAAP and non-GAAP basis.  The Company expects to end the quarter with
approximately $75 million of cash and investments.
    "Callidus Software, like many enterprise software companies, transacts a
significant portion of its quarterly business at the end of each quarter,"
stated Reed Taussig, president and CEO of Callidus Software.  "Our quarterly
license revenues are dependent on a relatively small number of large
transactions involving sales of our products to customers, and any delay or
failure in closing one or more of these transactions could adversely affect
our results of operations.  In this quarter, we failed to close several
transactions due to customers' merger and acquisition activities.  In
addition, a number of customers failed to conclude contracts due to their
timing or budgetary considerations.  We are disappointed with these results.
However, we continue to be optimistic about our business, given the potential
of the emerging EIM market, our product position, and our strong customer
base.  We will address second quarter and full year guidance on our planned
April conference call."
