                                        ACXIOM CORPORATION AND SUBSIDIARIES

                                                   CERTIFICATION

I, Rodger S. Kline, certify that:

1.   I have reviewed this annual report on Form 10-K of Acxiom Corporation;

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

3.   Based on my knowledge, the financial statements, and other financial information included in this annual
     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 annual 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 we
     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 the registrant's most recent fiscal quarter (the registrant's fourth fiscal quarter in
         the case of an annual report) that has materially affected, or is reasonably likely to materially
         affect, the registrant's internal control over financial reporting; and

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 the
     registrant's board of directors:

     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.
