  I,
        Steven R. Springsteel, certify that:
  1.
        I have reviewed this Annual Report on Form 10-K of Chordiant Software, Inc.;
  2.
        Based on my knowledge, this report does not contain any untrue statement
        of a
        material fact or omit to state a material fact necessary to make the statements
        made, in light of the circumstances under which such statements were made,
        not
        misleading with respect to the period covered by this report;
  3.
        Based on my knowledge, the financial statements, and other financial information
        included in this report, fairly present in all material respects the financial
        condition, results of operations and cash flows of the registrant as of,
        and
        for, the periods presented in this report;
  4.
        The registrant’s other certifying officer and I are responsible for establishing
        and maintaining disclosure controls and procedures (as defined in Exchange
        Act
        Rules 13a-15(e) and 15d-15(e) and internal control over financial reporting
        (as
        defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant
        and
        have:
  a.
        designed such disclosure controls and procedures, or caused such disclosure
        controls and procedures to be designed under our supervision, to ensure that
        material information relating to the registrant, including its consolidated
        subsidiaries, is made known to us by others within those entities, particularly
        during the period in which this annual report is being prepared;
  b.
        designed such internal control over financial reporting, or caused such internal
        control over financial reporting to be designed under our supervision, to
        provide reasonable assurance regarding the reliability of financial reporting
        and the preparation of financial statements for external purposes in accordance
        with generally accepted accounting principles;
  c.
        evaluated the effectiveness of the registrant’s disclosure controls and
        procedures and presented in this report our conclusions about the effectiveness
        of the disclosure controls and procedures, as of the end of the period covered
        by this report, based on such evaluation; and
  d.
        disclosed in this report any change in the registrant’s internal control over
        financial reporting that occurred during registrant’s most recent fiscal quarter
        that has materially affected, or is reasonably likely to materially affect,
        the
        registrant’s internal control over financial reporting.
  5.
        The registrant’s other certifying officer and I have disclosed, based on our
        most recent evaluation of internal control over financial reporting, to the
        registrant’s auditors and the audit committee of registrant’s board of directors
        (or persons performing the equivalent functions):
  a.
        all significant deficiencies and material weaknesses in the design or operation
        of internal control over financial reporting which are reasonably likely
        to
        adversely affect the registrant’s ability to record, process, summarize and
        report financial information; and
  b.
        any fraud, whether or not material, that involves management or other employees
        who have a significant role in the registrant’s internal control over financial
        reporting.
