Morgan, the Chairman of the Board of Directors and Chief Executive
Officer of the Issuer, with an offer (the "Offer") to acquire all shares
of the Company (collectively, the "Shares" and individually, a "Share")
that the Reporting Persons did not already own and reiterated their
desire to meet with Mr. Morgan, the Issuer's independent directors or
their advisors, to review and discuss any information that could lead to
a higher valuation.  The Board rejected the Offer without any direct
communication or discussion and without expressing any interest in
meeting with the Reporting Persons to share information that could lead
to a higher offer price. 

On October 21, 2005, the Reporting Persons sent a letter (the "Letter")
to the Board of Directors of the Issuer, which stated that the Reporting
Persons have continued their due diligence on the Issuer, identified and
retained three senior executives who are information services and
technology business experts, and are proceeding with their proposal to
acquire all of the Shares.

The Letter set forth the terms upon which one or more new entities to be
formed by VA Partners, LLC proposes to acquire all of the Shares at a
cash price of $25.00 per Share (the "Acquisition").  The Letter also set
forth the Reporting Persons' proposal to finance the Acquisition with a
combination of equity, senior debt and the issuance by the Issuer of
notes pursuant to a public placement or Rule 144A or other private
placement.  As stated in the Letter, the Reporting Persons received a new
highly confident letter from UBS Securities LLC for increased debt
financing of not less than $1.8 billion.  A copy of the Letter, which has
attached thereto a copy of a letter issued to the Reporting Persons by
UBS Securities LLC regarding potential debt financing in connection with
the Acquisition, is attached as Exhibit B to this report and is
incorporated herein by reference.

Re:  Acxiom Corporation (the "Company")

Ladies and Gentlemen of the Board of Directors:

The second-quarter results reported on October 19th further confirm our
belief that assets are being poorly deployed, opportunities missed, and that
shareholder value is being eroded by current management. It is clear to us
that there is an urgent need for a fundamental change in the Company's
strategic direction. It is also clear that the only way to bring about that
change is by replacing Acxiom's leadership. 

The results continue the Company's longstanding practice of financial
reporting marked by a lack of transparency and, frankly, candor. While
management trumpets top-line growth and pro forma profits, the significant
decline in true free cash flows tells a dramatically different story.
Acxiom's purported "free cash flow" calculation materially understates the
cash obligations that the current management team is imposing on the Company
and, ultimately, its shareholders, to fund its misguided and costly capital
expenditures. Notwithstanding management's claims to the contrary, the actual
free cash flow in the business has steadily declined, from $174 million in
FY2003, to $88 million in FY2004, to $55 million in FY2005, to a loss of $10
million through the first half of FY2006 (see attached Exhibit 1). And while
management claims progress on controlling costs, the facts indicate that they
are simply generating sales growth without any incremental profit increase.?
Sales increased $31.4 million in the quarter, while operating profit ("EBIT")
was effectively unchanged, even after allowing credit for $15.8 million of
one-time charges.? This "progress" is, in reality, profitless prosperity.

The lack of organic growth in Acxiom's services and data businesses in recent
quarters reflects management's evident inability to capitalize on the healthy


                               Page 11 of 17


growth of the marketing services industry.  This is in direct contrast to the
organic growth being shown at several of Acxiom's competitors over the six
months.  Both Harte-Hanks and Experian grew in the double digits internally
over their most recently reported six months, while it appears that Acxiom's
service and data business was roughly flat. As a result, management has
chosen instead to chase absolute sales growth in the low return-on-investment
IT management segment.  The Company won another large, highly capital
intensive outsourcing contract in a head-to-head competition with IBM. 
Should we believe that Acxiom has a lower cost of capital than IBM? Or that
Acxiom is more efficient than IBM? Does anyone really believe that it is a
sound long-term strategy to attempt to compete with IBM in the outsourcing
business? Such contracts typically require Acxiom to buy customer equipment,
to run parallel data centers, to indemnify the customer against privacy
issues, and to pass cost savings on to the customer.  We believe that these
contracts are fraught with risk, and that a continued strategy of growth in
this business imperils equity value today.

On July 12th, ValueAct Capital presented the Board with an offer (the
"Offer") to acquire all shares of the Company that we did not already own.
Our Offer, as presented, contained two components:  a price of $23 per share,
which at the time represented a 25% premium, and a willingness to consider a
higher offer price if allowed to meet with management and if we receive
additional information that would support such an increase. We provided
further details of our Offer in a subsequent letter on July 13th, in which we
reiterated our willingness to review and discuss any information that could
lead to a higher valuation. The Board rejected the Offer without any direct
communication or discussion with ValueAct Capital about it, and without
expressing any interest in meeting to share information that could lead to a
higher offer price.  

Since making our Offer, we have continued our due diligence on the Company,
both directly and with the assistance of industry experts.  We have also
identified and retained three senior executives who are successful, seasoned
information services and technology business experts, and they have
participated in and contributed to our external analysis of Acxiom as well.
We are convinced that there is real and substantial value in the Company if
led by a capable and experienced management team that will take the necessary
steps to significantly improve margins and free cash flow.

But it has to be recognized that a change in the Company's direction needs to
be made immediately.  Every month that goes by, the competitors are gaining
advantages and Acxiom uses up valuable assets, and falls behind in its
relevant markets. Having identified the right operating management team for
Acxiom, and having continued our external diligence process since first
making our Offer, we are confident that we still have time to correct the
"fool's gold" strategy that current management has continued to pursue with
grievous consequences to shareholder value.  Therefore, to preserve the
Company's value, we feel that it is urgent to act now.

This letter sets forth the terms upon which one or more new entities
("Newco") to be formed by VA Partners, LLC ("ValueAct Capital") proposes to
acquire (in the "Acquisition") all of the outstanding shares of the Company
that ValueAct Capital and its affiliates do not already own at a cash price


                               Page 12 of 17


of $25.00 per share of Company common stock (the "Purchase Price").  Further,
we believe it again worth emphasizing that if given an opportunity to meet
with the Board or its advisors, and/or with Company management, and if we
receive additional information about the Company on a confidential basis, we
may learn information that would permit us to offer a higher purchase price.
  
We believe that an Acquisition must be, and can be, completed quickly.
Furthermore, by proceeding expeditiously towards the negotiation and
execution of a definitive merger agreement with Newco, we believe the Company
can obtain value for all its shareholders promptly while minimizing
disruption to the Company's business, employees, and competitive position.

Financing:  We propose to finance the Acquisition with a combination of
equity, senior debt and the issuance by the Company of notes pursuant to a
public placement or Rule 144A or other private placement.  Since our last
offer, ValueAct Capital has continued to work closely with UBS Securities LLC
("UBS"). Based on its work with ValueAct Capital and its management partners,
UBS has provided a new highly confident letter that is enclosed, for
increased debt financing of not less than $1.8 billion.  In conjunction with
this debt financing, ValueAct Capital is prepared to commit the remaining
equity required for the purchase of the Company's securities, the refinancing
of the Company's existing debt and the funding for the fees and expenses
pertaining to the Acquisition.  

Structure:  The Acquisition would be structured as a one-step merger with a
wholly-owned subsidiary of Newco merging into the Company.  Pursuant to the
merger, all shares of the Company's common stock (other than the shares held
by Newco or an affiliate of Newco) would be cashed out at the Purchase Price.
Options with an exercise price less than the Purchase Price would be cashed
out in the merger; options with an exercise price greater than the Purchase
Price would be cancelled.  Warrants would be cashed out in the merger.  We
are prepared to consider allowing management who remain with the Company to
roll over their options or warrants into Newco equity.  We also expect to
establish a new management incentive plan.

Definitive Agreement; Conditions:  The terms of the transactions set forth
herein will be set forth in a definitive agreement that will include standard
representations, warranties and covenants for a public company transaction
and that will be satisfactory in form and substance to Newco and the Company.  

ValueAct Capital believes that we will be able to complete all the necessary
steps of the transaction in an efficient and expeditious manner. We encourage
the Board to give this offer its immediate and serious consideration.   We
remain ready to meet with your independent directors or their advisors at
their earliest convenience to discuss this proposed Acquisition.

Sincerely,
/s/ Jeffrey W. Ubben

It is common to treat the costs of acquiring capital assets and software
licenses as deductions from free cash flow, regardless of how they are
financed, as a more accurate representation of free cash flow that is
available to equity holders.

Acxiom's true free cash flow has declined dramatically over the last three
years and has been negative in the first six months of fiscal 2006.

Attention: Jeffrey W. Ubben


                      Highly Confident Letter


Ladies and Gentlemen:

          ValueAct Capital Partners, L.P. ("you" or "Sponsor") has
advised UBS Securities LLC ("UBSS", "us" or "we") that you propose to,
through a newly created company (the "Company"), acquire (the
"Acquisition") Acxiom Corporation (the "Acquired Business") pursuant to
a purchase agreement. All references to "dollars" or "$" in this letter
are references to United States dollars. All references to the Company
herein shall be deemed to include the Company and its subsidiaries,
including the Acquired Business on a post-Acquisition basis.

          You have informed us that the aggregate cash purchase price,
together with existing debt to be refinanced and fees, commissions and
expenses, will be funded with at least $670 million of new cash equity
to be contributed by the Sponsor and $1.8 billion in debt financing
(the "Debt Financing"). The Debt Financing will include borrowings by
the Company under a senior secured credit facility, including a
revolver in an amount to be determined to fund the Company's ongoing
working capital needs (the "Credit Facility"), and the issuance by the
Company of notes or other debt securities pursuant to a public offering
or Rule 144A or other private placement (the "Notes").

          Based upon an initial review of certain public information
provided by you relating to the Acquisition and the Acquired Business,
we are pleased to inform you that, as of the date hereof and subject to
the factors listed below, we are highly confident of our ability to
arrange the Debt Financing for the Acquisition.

          We have assumed that the structure, covenants and terms of
the Debt Financing will be as determined by UBSS and its affiliates in
consultation with you based on (i) market conditions at the time of the
syndication, offering or placement of the Debt Financing, (ii) the
structure and documentation of the Acquisition and related transactions
and (iii) the financial prospects of the Company at the time of sale.


                               Page 15 of 17


          Our view is based upon the assumption that (i) there will be
no change, or the disclosure of any additional information to, or
discovery of additional information by, UBSS (including, without
limitation, information contained in any review or report provided to
UBSS in connection with the Debt Financing) which UBSS deems to be
materially adverse in respect of the business, results of operations,
condition (financial. or otherwise), assets, liabilities or prospects
of the Company; (ii) there will not occur, in the judgment of UBSS, a
material adverse change or material disruption in the financial,
banking or capital markets generally after the date of this letter
(including, without limitation, the markets for loans to or debt
securities issued by companies similar to the Company) that could
reasonably be expected to have a material adverse effect on the
syndication of the Credit Facility or the marketing of the Notes; (iii)
the definitive documentation for the Acquisition and related trans-
actions (including, without limitation, the documents relating to the
Credit Facility and the Notes, including an underwriting agreement or
placement agreement, a registration rights agreement and other
documents in UBSS's standard forms) wil1 be prepared, executed and
delivered, and will be in form and substance reasonably satisfactory to
UBSS and all conditions set forth in such documentation will be
satisfied; (iv) all requisite regulatory, governmental, shareholder and
other third party approvals required to consummate the Acquisition, the
Debt Financing and all related transactions will be timely received;
(v) UBSS will have a reasonable time to market the Debt Financing based
on its experience in comparable transactions and market conditions, and
the marketing process will be conducted in a manner satisfactory to
UBSS and, in the case of the Notes, utilize offering materials that
contain all financial and non-financial information required by the
Securities Act of 1933 (whether or not the Notes are sold in a
transaction registered under such Act) and the rules and regulations
thereunder for registration statements on Form S-l filed thereunder
