                                                      CERTIFICATION

I, Charles D. Morgan, certify that:

1.   I have reviewed this quarterly report on Form 10-Q of Acxiom Corporation;

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 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 quarterly 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 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.
