          Re:  Marketing Services Division Agreement

     Dear Jim:

          On July 27, 1992, Trans Union and Acxiom entered into a
     Data Center Management Agreement ("DCMA").  Recently, Trans
     Union and Acxiom have discussed a proposal ("Proposal") by
     Acxiom to improve the efficiency of certain data processing
     services used in the to-be-defined operation of the
     Marketing Services Division (excluding, without limitation,
     the List and Insurance divisions) of Trans Union ("MSD"). 
     The parties mutually acknowledge and agree that this letter
     is not intended to create any binding contractual or legal
     obligations upon either party with respect to the subject
     matter of the Proposal.  The purpose of this letter is to
     summarize a potential transaction.  The parties agree to
     negotiate in good faith a definitive and binding agreement
     ("Agreement"), but either party may terminate such
     negotiations at any time for any or no reason.

          1.  Development.  On a mutually agreed upon schedule of
     milestones and benchmarks (with completion on or before
     July, 1996), Acxiom will develop certain computer software
     and related technical materials and processes and undergo
     certain conversions for MSD (the "MSD Software"), so as to
     enable Acxiom to provide, pursuant to the Agreement, all
     data processing services and software systems necessary for
     MSD's operations from Acxiom's data center in Conway,
     Arkansas from and after an agreed cutover date.  Acxiom will
     contribute leadership and product knowledge by dedicating a
     business unit executive and all required programming,
     customer service and support personnel to the development
     and operations, and Acxiom will provide appropriate training
     and consulting services to Trans Union to enable Trans Union
     to utilize the MSD Software and related new systems.  The
     foregoing will be at Acxiom's sole cost, expense and
     responsibility.  Trans Union will retain all rights, title,
     and ownership in and to the MSD Software and its components
     (whether tangible or intangible) developed in connection
     with this Proposal, including without limitation all
     copyright, patent, trade secrets and other proprietary
     rights pertaining thereto.

          2.    Efforts by Trans Union.  Trans Union will at
     cost: (i) provide facilities and resources, and (ii) furnish
     technical personnel (including programming, customer
     service, support personnel, and personnel with market
     knowledge) to assist in Acxiom's efforts.  
 
          3.    Standards.  Service levels and acceptance
     standards will be established.  An executive committee
     comprised of officers of each party will be established to
     have general oversight over the development and operations
     effort.  The establishment and operation of such executive
     committee will not diminish Acxiom's duty to develop the MSD
     Software as described in paragraph 1 herein.

          4.    Pricing and Payments:

                4.1   Payments by Acxiom.  In consideration for
     the services to be provided by Trans Union in paragraph 2
     herein, Acxiom will pay Trans Union on terms and conditions
     to be agreed upon.  Acxiom will reimburse Trans Union for
     all expenses incurred by Trans Union in connection with such
     services.

                4.2   Payments by Trans Union.  In consideration
     for the development and other services of Acxiom, for each
     twelve month period of September 1 through August 31
     ("Applicable Year") beginning with the first full Applicable
     Year throughout which the MSD Software is fully implemented,
     and until the year ending on August 31, 2002 (unless the
     DCMA is earlier terminated), Trans Union will pay Acxiom an
     amount calculated on the basis of terms, conditions and
     formulas which are yet undetermined but which are
     contemplated by the parties to include a portion of a to-be-
     defined improvement in MSD profit margin.

                4.3   Cost Savings.  Notwithstanding anything to
     the contrary stated herein or in the DCMA, the Data Center
     Management fee as defined by the DCMA would be reduced by
     100% of the net reduction in Acxiom's Data Center cost
     (including without limitation reduction in processing costs
     and personnel costs resulting from the development and
     operations) ("Cost Reduction").  The Cost Reduction includes
     without limitation reduction in cost due to the use of the
     MSD Software and reduction in cost due to the transfer of
     systems and services to Conway, Arkansas.  For any
     Applicable Year in which the Cost Reduction is less than a
     to-be-determined "Guarantee" (contemplated by the parties to
     be at least ten percent (10%) of a to-be-determined base MSD
     cost level), Acxiom will pay Trans Union the difference
     between the Guarantee and the Cost Reduction.  Trans Union
     will have the right immediately to apply and set off any and
     all such amounts against, and in payment of, any and all
     amounts then or thereafter payable by Trans Union to Acxiom
     under any provision of the DCMA.

          5.   The Data Center Management Agreement.  The
     Agreement would not amend or modify any terms or provisions
     of the DCMA, nor would the provision of services under the
     Agreement have any effect on Acxiom's obligations arising
     under the DCMA, except as specifically provided herein.  In
     particular, and in accordance with Section 5.8 of the DCMA,
     Acxiom would remain obligated to pay Trans Union the stated
     portion (approximately 50%) of the Savings not subject to
     paragraph 4.3 herein.


          If the above sets forth your understanding of the
     status of our discussions with respect to the Proposal,
     please execute one copy of this letter in the space provided
     below and return a fully executed copy to me.

                               Very Truly Yours,


                               TRANS UNION CORPORATION


                               /s/ Ralph Sorice
