            1.    I have reviewed this quarterly report on Form 6-K of Infosys
      Technologies Limited;

            2.    Based on my knowledge, this quarterly 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 quarterly 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
      quarterly report;

            4.    The registrant's other certifying officers and I are
      responsible for establishing and maintaining disclosure controls and
      procedures (as defined in Exchange Act Rules 13a-14 and 15d-14) for the
      registrant and we have:

                  a)    designed such disclosure controls and procedures 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 quarterly report is being prepared;

                  b)    evaluated the effectiveness of the registrant's
            disclosure controls and procedures as of a date within 90 days prior
            to the filing date of this quarterly report (the "Evaluation Date");
            and

                  c)    presented in this quarterly report our conclusions about
            the effectiveness of the disclosure controls and procedures based on
            our evaluation as of the Evaluation Date;

            5.    The registrant's other certifying officers and I have
      disclosed, based on our most recent evaluation, to the registrant's
      auditors and the audit committee of registrant's board of directors (and
      persons performing the equivalent functions):

                  a)    all significant deficiencies in the design or operation
            of internal controls which could adversely affect the registrant's
            ability to record, process, summarize and report financial data and
            have identified for the registrant's auditors any material
            weaknesses in internal controls; and

                  b)    any fraud, whether or not material, that involves
            management or other employees who have a significant role in the
            registrant's internal controls; and

            6.    The registrant's other certifying officers and I have
      indicated in this quarterly report whether or not there were significant
      changes in internal controls or in other factors that could significantly
      affect internal controls subsequent to the date of our most recent
      evaluation, including any corrective actions with regard to significant
      deficiencies and material weaknesses.
