ITEM 4.  PURPOSE OF TRANSACTION.

         On June 3, 2005, the Reporting Persons sent a letter (the "Letter")
to Mr. Charles Morgan, the Chairman of the Board of Directors and Chief
Executive Officer of the Issuer, expressing the Reporting Persons'
disappointment that the Board of Directors has not followed through on any of
the major public commitments it has made to increase shareholder value,
essentially abandoning the Issuer's improved return-on-investment plans
publicly communicated in May of 2004.  The Letter reiterated the Reporting
Persons' concerns regarding the strength of the Issuer's current financial
management. The Letter also stated that, after carefully reviewing the facts
and the performance of the Issuer's stock price, the Reporting Persons
believe fresh participation at the Board level is needed to help challenge
management and bring critical financial acumen, and that the Reporting
Persons are now prepared to offer to acquire all of the outstanding shares of
the Issuer not already owned by the Reporting Persons at a cash price of
$23.00 per share, subject to a satisfactory due diligence review of the
Issuer. A copy of the Letter is attached as Exhibit B to this report and is
incorporated herein by reference.

                         VAC
                        VALUEACT CAPITAL
                       June 3, 2005

VIA E-MAIL AND FEDERAL EXPRESS

Mr. Charles Morgan
Chairman and Chief Executive Officer
Acxiom Corporation
1 Information Way
Little Rock, AR 72202

Dear Charles:

Beginning in the mid-1990's, principals of ValueAct Capital began
following Acxiom Corporation (the "Company"). We watched the Company
for many years before making our first purchase of Acxiom stock in June
of 2003. At that time we were attracted by the apparent resilience
demonstrated by Acxiom in the face of highly challenging business and
market conditions and by the Company's dramatic improvement in cash
generation from fiscal 2001 through fiscal 2003. Although we observed
some fundamental weaknesses in the management of the business, we were
impressed by Acxiom's stated plans to leverage its rich data assets
into higher margin products, to develop a more scaleable service
delivery model, and to operate with increased return-on-investment
discipline. Based on comments by the Company to this effect, and on our
continued due diligence, we increased our investment through the course
of 2003.

In December of 2003 we met with you and advocated a public commitment
to a Return on Assets (ROA) goal. An ROA goal was ultimately
communicated to the public in May of 2004 in the Financial Roadmap. The
May 2004 Financial Roadmap had a "long term goal" for ROA of 14-16%.
The market's positive response to the introduction of the Company's
Financial Roadmap was immediate and Acxiom's stock rose to multi-year
highs. ValueAct Capital continued to add to its investment position
based on our belief that Acxiom was strongly committed to the value
creating strategies underlying the Financial Roadmap. 

However, we have been dismayed to see that not only have Acxiom's
actions been in contrast to these stated goals, but that the Board of
Directors of the Company has demonstrated a lack of willingness to
acknowledge obvious management deficiencies and missteps and to take
steps to put the Company on the path to strong financial performance. 

Acxiom has not followed through on any of the major commitments it has
made to increase shareholder value. Rather than holding to its pubic
commitments to achieve meaningful margin expansion and increase
returns-on-investment by driving growth with data products and by
developing more standardized service delivery processes, Acxiom has
instead chosen to drive growth through expansion of the IT Management
segment, which is demonstrably the Company's lowest return, most
capital intensive business. The Company has essentially abandoned the

                               Page 11 of 12


improved return-on-investment plans communicated in the May 2004
Financial Roadmap by lowering the long-term ROA goal from 14-16% to 10
14% (May 12, 2005 Roadmap). The lower ROA range moves the Company much
closer to not earning its current cost of capital. 

As you know, we have questioned the strength of the Company's financial
management for some time. These concerns crystallized when it became
apparent that management miscalculated the benefit of the Claritas and
Consodata acquisitions. The original business reasons for these
acquisitions may have been sound, but the financial analysis,
forecasting and capital allocation processes were flawed. We were
further troubled when the Company decided to exclude sizeable capital
lease additions from the Roadmap definition of "Free Cash Flow". Based
on discussions we had with you, we believed that you agreed with our
view that the Company's financial expertise needed to be upgraded and
strengthened, but we were disappointed and surprised when you later
told us that the current financial management was "just fine".

Based on all of these facts and the performance of Acxiom's stock
price, it is clear that the Company needs fresh and independent
participation at the board level to help challenge management and bring
critical financial acumen. When we began discussions about my possible
addition to the Board, we believed that the Board recognized that it
could benefit from the involvement of a Board member with extensive
financial and public company board experience. At a minimum we thought
that the Company was now committed to making major changes at the Board
level. We now understand that the Acxiom Board of Directors was only
making changes at the Board level to satisfy a NASDAQ corporate
governance requirement and not to make a serious change that could
improve the effectiveness of the Board. 

As Acxiom's largest shareholder for nearly two years, we are no longer
willing to sit on the sidelines as opportunities are lost and equity
value is destroyed. The current regime has proven its inability to
generate sustained equity returns over a ten-year period. Now that the
promises of the last two years have proved to be illusory, it is time
for the Board to put the Company in the hands of someone who recognizes
the opportunity to unlock the Company's potential value and who is
willing to provide appropriate value to shareholders today for such
opportunity.

To that end, ValueAct Capital is prepared to present an offer to
acquire 100% of the shares of Acxiom that we do not already own at a
purchase price of $23.00 per share, a 25% premium to the 20-day average
of closing prices for Acxiom common shares. We would prefer to meet
with you, your independent directors or their advisers, at the earliest
possible time to discuss these matters. Please be aware that ValueAct
Capital is required to amend its current 13D filing to include this
letter and intends to do so on Monday afternoon, June 6th.

Sincerely,

/s/ Jeffrey W. Ubben

Jeffrey W. Ubben
Managing Partner
