1. I have reviewed this Form 10-Q of
Niku Corporation;



2. Based on my knowledge, this quarterly

covered by this report;



3. Based on my knowledge, the
financial statements, and other financial information included in this quarterly 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)) 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 report is being prepared;



(b) 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



(c) disclosed in this report any change in the registrants internal

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 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 data; 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.
