The Plan Administrator
Acxiom Corporation Retirement Savings Plan:


We have audited the accompanying  statements of net assets  available for benefits of the Acxiom  Corporation  Retirement  Savings
Plan (the Plan) as of  December 31,  2004 and 2003, and the related  statement of changes in net assets  available for benefits for
the year ended December 31,  2004. These financial statements are the responsibility of the Plan's management.  Our responsibility
is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance  with the standards of the Public  Company  Accounting  Oversight  Board  (United States).
Those standards  require that we plan and perform the audit to obtain  reasonable  assurance about whether the financial  statements
are free of material  misstatement.  An audit  includes  examining,  on a test basis,  evidence  supporting  the amounts and
disclosures in the financial  statements.  An audit also includes assessing the accounting  principles used and significant
estimates made by management, as well as evaluating the overall  financial  statement  presentation.  We believe that our audits
provide a reasonable  basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly,  in all material  respects,  the net assets available
for benefits of the Acxiom Corporation  Retirement  Savings Plan as of December 31,  2004 and 2003, and the changes in net assets
available for benefits for the year ended December 31, 2004, in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial  statements  taken as a whole.  The
supplemental schedule of assets  (held at end of year) is  presented  for purposes of  additional  analysis and is not a required
part of the basic financial  statements,  but is supplementary  information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee  Retirement Income Security Act of 1974. This supplemental  schedule is
the  responsibility of the Plan's management.  The  supplemental  schedule has been  subjected to the auditing  procedures  applied
in the audits of the basic  financial statements  and, in our opinion,  is fairly stated in all material  respects in relation to
the basic financial  statements  taken as a whole.

                                                      December 31, 2004 and 2003



(1)      Plan Description

       The following  description of the Acxiom  Corporation  Retirement  Savings Plan  (the Plan)  provides only general
       information. Participants should refer to the Plan agreement (the Agreement) for a more complete description of the Plan's
       provisions.

        (a)      General

              The Plan is a defined  contribution  Plan covering  substantially  all employees of Acxiom  Corporation  and its
              domestic subsidiaries  (Acxiom,  the Company or the Employer).  The Plan is subject to the  provisions of the Employee
              Retirement Income Security Act of 1974 (ERISA), as amended.

        (b)      Contributions

              The Plan  includes a 401(k)  provision  whereby each  non-highly  compensated  participant  may defer up to 30% of
              annual compensation not to exceed limits  determined  under  Section 415(c)  of the Internal  Revenue Code (IRC).
              Deferrals for highly compensated  participants are limited to meet nondiscrimination  requirements of the IRC and are
              currently limited to 6% of annual compensation.

              The Plan has historically  provided a matching  contribution of 50% of deferrals for deferrals up to 6% (maximum
              matching contribution of 3%). During 2003 the Plan was amended to allow the Company to provide  discretionary instead
              of mandatory matching  contributions.  From  August 1,  2003 until  October 31,  2003, the  discretionary  matching
              contribution  was suspended. On November 1,  2003, the discretionary matching contribution was reinstated at the level
              of 25% for deferrals up to 6% (maximum matching  contribution of 1.5%). During the 2004 plan year, March 1,  2004, the
              discretionary match was increased back to its prior level of 50% of 6%, for a maximum 3.0%.

              Participant  contributions  to the Plan are invested as directed by participants  into various  investment  options.
              The Company's  matching  contributions  are made with Acxiom  common  stock and are  recorded  based on the fair value
              of the common stock at the date contributed.  During the years ended December 31,  2004 and 2003 the Company
              contributed 228,488 and 142,481 shares,  respectively,  of Acxiom common stock.  Immediately upon deposit into the
              Plan, the match shares are 100% diversifiable, at the election of the Participant, among the other investment options
              with the Plan.

              Certain fees for  attorneys,  accountants,  and Plan  administration  have been paid by the Company during the year
              ended December 31,  2004. The Company may continue to pay these fees in the future, if it so chooses;  otherwise,
              fees will be paid out of the trust of the Plan.

        (c)      Participant Accounts

              Each participant's  account is credited with the participant's  contribution,  the Company's matching  contribution,
              and discretionary contributions, if any, and is adjusted for investment income/losses.  Allocations of income/losses
              are made according to formulas  specified in the Agreement based on participant  compensation or account balances.
              The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested
              account.

                                                                4

        (d)      Participant Notes Receivable

              Participants  may borrow from their fund  accounts a minimum of $1,000 up to a maximum  equal to the lesser of $50,000
              or 50% of their vested account balance.  Loans are repayable through payroll  deductions ranging up to five years
              unless the loan is for the  purchase  of a primary  residence,  in which case the loan can be repaid  over ten years.
              The loans are secured by the  balance in the  participant's  account  and bear  interest at the prime rate in effect
              at the date of the loan plus 2%. The interest rates on outstanding participant loans at December 31, 2004 and 2003
              range from 6.0% to 11.5%.

        (e)      Vesting

              Participants are immediately  vested in their voluntary  contributions and the earnings thereon.  Participants are
              vested in the remainder of their accounts based on years of service,  whereby partial vesting occurs in 20% increments
              beginning after two years of service until participants  become fully vested after six years of service.  If
              applicable,  nonvested portions of Company  contributions  are  forfeited as of an  employee's  termination  date and
              are used to reduce  future Company matching contributions or to pay Plan expenses.

              At December 31, 2004 and 2003, forfeited nonvested accounts totaled $854,378 and $431,925,  respectively.  These
              accounts will be used to reduce future Employer  contributions.  During 2004 $1,552,062 of  participants'  accounts
              were forfeited and Employer  contributions  were reduced by $1,350,096  from forfeited  nonvested  accounts.  During
              2004 the forfeiture account balance was also increased by $220,487 on the fair market value of the investments held
              in the account.

       (f)      Investment Options

              Upon  enrollment in the Plan, a participant may direct  employee  contributions  in any of 18 mutual funds and one
              common collective trust fund currently  offered by T. Rowe Price Investment  Services,  Inc.  (T. Rowe Price)  (see
              note 4).  In addition,  participants  have the option to open a self-directed  brokerage account with T. Rowe Price in
              order to invest in numerous  other  stocks,  bonds,  and mutual  funds.  Acxiom  common stock is also an  investment
              option for employee contributions.  For the years ended December 31,  2004 and 2003,  employee  contributions to the
              Acxiom common stock fund were $216,858 and $158,601, respectively.

              The Plan's  investment  in the T. Rowe  Price  Stable  Value Fund  (the Fund),  a common  trust fund,  holds
              substantial investments in guaranteed investment contracts,  bank investment contracts, and synthetic investment
              contracts. The value of the Fund  reflects the value of the  underlying  contracts,  which consist of changes in
              principal  value,  reinvested dividends and capital gains distributions,  and approximate fair market value. The
              stated interest rates of the contracts vary and the average yield for the year ended December 31, 2004 was 4.40%
              after expenses.

              The Plan's  investment  in the T. Rowe Price  Equity  Index Trust (the Trust),  a common  trust fund,  holds
              substantial investments  in common stocks of companies  that comprise the S&P Index.  The returns from the
              investments  vary and the average yield for the year ended December 31, 2004 was 10.94% after expenses.

                                                                5

        (g)      Withdrawals and Payment of Benefits

              Benefits paid upon  retirement,  death, or disability are made in the form of a lump-sum  payment of cash or common
              stock of the Company. If a participant receives benefits prior to retirement,  death, or disability, the benefits paid
              from the participant's Employer contribution account shall not exceed the participant's vested balance therein.

        (h)      Net Assets Transferred from Other Plans

              On March 31, 2004, the account balances of all current  participants in the Computer Graphics of Arizona  Retirement
              Plan and Trust (CG 401(k)  Plan) were  transferred  to the Plan.  The sum of the  participant  account  balances  in
              each Plan equaled the fair market value of the Plan (determined as of the date of the merger).  Immediately after the
              merger,  each participant  in the merged  Plan had an account  balance  equal to the sum of the  account  balances he
              or she had in the Plans immediately prior to the merger.  Separate  accounts for the affected  participants  shall be
              established under the Plan to receive  and  account  for the  merged CG 401(k)  account.  There  were no  reductions
              of  accrued  benefits  to participants as a result of the merger.

(2)      Summary of Significant Accounting Policies

        (a)      Basis of Accounting

              The financial statements of the Plan are prepared under the accrual method of accounting.

        (b)      Use of Estimates

              The preparation of financial statements in conformity with accounting  principles generally accepted in the United
              States of America  requires  management  to make  estimates  and  assumptions  that  affect the  reported  amounts of
              assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial  statements
              and the reported amounts of additions to and  deductions  from net assets during the reporting  period.  Actual
              results could differ from those estimates.

        (c)      Investment Valuation and Income Recognition

              The  Plan's  investments  are stated at fair  value,  based upon  quoted  market  prices,  except for  participant
              notes receivable,  which are  stated at unpaid  principal  balance,  which  approximates  fair  value.  Purchases  and
              sales of securities and related income are recorded on a trade date basis.

              The Plan provides for  investment in  investment  securities  that,  in general,  are exposed to various  risks,  such
              as interest rate,  credit,  and overall  market  volatility.  Due to the level of risk  associated  with certain
              investment securities, changes can materially affect the amounts reported in the statements of net assets available
              for benefits.

        (d)      Payment of Benefits

              Benefits are recorded when paid.

                                                                6

(3)      Investments

              The fair value of the individual investments held by the Plan is as follows:

                                                     Notes to Financial Statements

                                                      December 31, 2004 and 2003





(4)      Plan Administration

       The Plan is administered  by the Company.  During 2004 and 2003  participant  records and assets have been maintained by T.
       Rowe Price Trust Company as recordkeeper and trustee (see note 6).

(5)      Tax Status

       The Internal  Revenue Service has determined and informed the Company by a letter dated July 21,  2003 that the Plan is
       designed in accordance with applicable sections of the IRC. The Plan has been amended since receiving the determination
       letter. The Plan Administrator  and the Plan's tax counsel believe that the Plan is currently  designed and being operated
       in compliance with the applicable requirements of the IRC.

(6)      Parties in Interest

       All investment  transactions were executed with T. Rowe Price Trust Company,  the Plan's trustee and recordkeeper, which is a
       party in interest. During 2004 and 2003, total fees paid to T. Rowe Price were $19,569 and $19,519, respectively.

(7)      Plan Termination

       Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its  contributions
       at any time and to  terminate  the Plan  subject  to the  provisions  of ERISA.  Upon  complete  discontinuance  of
       contributions, termination,  or partial  termination of the Plan,  participants  will become 100% vested in their accounts,
       in which event the value of such accounts shall be distributed as provided in the Plan.

(8)      Reconciliation to Form 5500

       Participant  directed brokerage  accounts are reported in the aggregate on Form 5500 but are classified  according to
       investment type in the statements of net assets available for benefits. As of December 31,  2004 and 2003,  participant-
       directed  brokerage accounts included $0 and $444,492 of mutual fund investments and $0 and $191,080 of common stock
       investments, respectively.
