                       FIRST AMENDMENT TO TRUST AGREEMENT
                 BETWEEN FIDELITY MANAGEMENT TRUST COMPANY AND
                          INFORMATION RESOURCES, INC.


     THIS FIRST AMENDMENT, effective as of the first day of March, 1997, by and
between Fidelity Management Trust Company (the "Trustee") and Information
Resources, Inc. (the "Sponsor");

                                  WITNESSETH:

     WHEREAS, the Trustee and the Sponsor heretofore entered into a Trust
Agreement dated July 1, 1996, with regard to the Information Resources, Inc.
401(k) Retirement Savings Plan (the "Plan"); and

     WHEREAS, the Trustee and the Sponsor now desire to amend said Trust
Agreement as provided for in Section 13 thereof;

     NOW THEREFORE, in consideration of the above premises, the Trustee and the
Sponsor hereby amend the Trust Agreement by:


     (1)  Amending Section 4(b) by adding the following subsection where
appropriate:

          (iii)  equity securities issued by the Sponsor or an affiliate which
are publicly-traded and which are "qualifying employer securities" within the
meaning of section 407(d)(5) of ERISA ("Sponsor Stock").


     (2)  Amending Section 4 by inserting the following new Section 4(g) and
relettering existing subsections and any cross references accordingly:

          (g)  Sponsor Stock.  Trust investments in Sponsor Stock shall be made
          via the Information Resources Stock Fund (the "Sponsor Stock Fund")
          which shall consist of shares of Sponsor Stock and short-term liquid
          investments, including Fidelity Institutional Cash Portfolios: Money
          Market Portfolio: Class 1 or such other Mutual Fund or commingled
          money market pool as agreed to by the Sponsor and Trustee, necessary
          to satisfy the Fund's cash needs for transfers and payments.  A cash
          target range shall be maintained in the Sponsor Stock Fund.  Such
          target range may be changed as agreed to in writing by the Sponsor and
          the Trustee. The Trustee is responsible for ensuring that the actual
          cash held in the Sponsor Stock Fund falls within the agreed upon range
          over time.  Each Participant's proportional interest in the Sponsor
          Stock Fund shall be measured in units of participation, rather than
          shares of Sponsor Stock.  Such units shall represent a proportionate
          interest in all of the assets of the Sponsor Stock Fund, which
          includes shares of Sponsor Stock, short-term investments and at times,
          receivables

                                       1
<PAGE>
 
          for dividends and/or Sponsor Stock sold and payables for Sponsor Stock
          purchased.  A Net Asset Value ("NAV") per unit will be determined
          daily for each unit outstanding of the Sponsor Stock Fund. The return
          earned by the Sponsor Stock Fund will represent a combination of the
          dividends paid on the shares of Sponsor Stock held by the Sponsor
          Stock Fund, gains or losses realized on sales of Sponsor Stock,
          appreciation or depreciation in the market price of those shares
          owned, and interest on the short-term investments held by the Sponsor
          Stock Fund. Dividends received by the Sponsor Stock Fund are
          reinvested in additional units of the Sponsor Stock Fund. Investments
          in Sponsor Stock shall be subject to the following limitations:

               (i)    Acquisition Limit.  Pursuant to the Plan, the Trust may be
          invested in Sponsor Stock to the extent necessary to comply with
          investment directions under Section 4(c) of this Agreement.

               (ii)   Fiduciary Duty of Named Fiduciary.  The Named Fiduciary
          shall continually monitor the suitability under the fiduciary duty
          rules of section 404(a)(1) of ERISA (as modified by section 404(a)(2)
          of ERISA) of acquiring and holding Sponsor Stock.  The Trustee shall
          not be liable for any loss, or by reason of any breach, which arises
          from the directions of the Named Fiduciary with respect to the
          acquisition and holding of Sponsor Stock, unless it is clear on their
          face that the actions to be taken under those directions would be
          prohibited by the foregoing fiduciary duty rules or would be contrary
          to the terms of the Plan or this Agreement.

               (iii)  Execution of Purchases and Sales.

                      (A)  Purchases and sales of Sponsor Stock (other than for
          exchanges) shall be made on the open market on the date on which the
          Trustee receives from the Sponsor in good order all information and
          documentation necessary to accurately effect such purchases and sales
          (or, in the case of purchases, the subsequent date on which the
          Trustee has received a wire transfer of the funds necessary to make
          such purchases).  Exchanges of Sponsor Stock shall be made in
          accordance with the Telephone Exchange Guidelines attached hereto as
          Schedule "G".  Such general rules shall not apply in the following
          circumstances:

                                       2
<PAGE>
 
                           (1)   If the Trustee is unable to purchase or sell
          the total number of shares required to be purchased or sold on such
          day as a result of market conditions; or

                           (2)     If the Trustee is prohibited by the
          Securities and Exchange Commission, the New York Stock Exchange, or
          any other regulatory body from purchasing or selling any or all of the
          shares required to be purchased or sold on such day.

          In the event of the occurrence of the circumstances described in (1)
          or (2) above, the Trustee shall purchase or sell such shares as soon
          as possible thereafter and shall determine the price of such purchases
          or sales to be the average purchase or sales price of all such shares
          purchased or sold, respectively.  The Trustee may follow directions
          from the Named Fiduciary to deviate from the above purchase and sale
          procedures provided that such direction is made in writing by the
          Named Fiduciary.

                      (B)  Purchases and Sales from or to Sponsor.  If directed
          by the Sponsor in writing prior to the trading date, the Trustee may
          purchase or sell Sponsor Stock from or to the Sponsor if the purchase
          or sale is for adequate consideration (within the meaning of section
          3(18) of ERISA) and no commission is charged.  If Sponsor
          contributions or contributions made by the Sponsor on behalf of the
          Participants under the Plan are to be invested in Sponsor Stock, the
          Sponsor may transfer Sponsor Stock in lieu of cash to the Trust.  In
          either case, the number of shares to be transferred will be determined
          by dividing the total amount of Sponsor Stock to be purchased or sold
          by the 4:00 p.m. closing price of the Sponsor Stock on the New York
          Stock Exchange on the trading date.

                      (C)  Use of an Affiliated Broker.  The Sponsor hereby
          directs the Trustee to use Fidelity Brokerage Services, Inc. ("FBSI")
          to provide brokerage services in connection with any purchase or sale
          of Sponsor Stock in accordance with directions from Plan Participants.
          FBSI shall execute such directions directly or through its affiliate,
          National Financial Services Company ("NFSC").  The provision of
          brokerage services shall be subject to the following:

                                       3
<PAGE>
 
                           (1)   As consideration for such brokerage services,
          the Sponsor agrees that FBSI shall be entitled to remuneration under
          this authorization provision in the amount of three and one-half cents
          ($.035) commission on each share of Sponsor Stock.  Any change in such
          remuneration may be made only by a signed agreement between Sponsor
          and Trustee.

                           (2)   Following the procedures set forth in
          Department of Labor Prohibited Transaction Class Exemption 86-128, the
          Trustee will provide the Sponsor with the following documents: (1) a
          description of FBSI's brokerage placement practices; (2) a copy of
          PTCE 86-128; and (3) a form by which the Sponsor may terminate this
          authorization to use a broker affiliated with the Trustee.  The
          Trustee will provide the Sponsor with this termination form annually.

                           (3)   Any successor organization of FBSI, through
          reorganization, consolidation, merger or similar transactions, shall,
          upon consumption of such transaction, become the successor broker in
          accordance with the terms of this authorization provision.

                           (4)   The Trustee and FBSI shall continue to rely on
          this authorization provision until notified to the contrary.  The
          Sponsor reserves the right to terminate this authorization upon
          written notice to FBSI (or its successor) and the Trustee, in
          accordance with Section 11 of this Agreement.

               (iv)   Securities Law Reports.  The Named Fiduciary shall be
          responsible for filing all reports required under Federal or state
          securities laws with respect to the Trust's ownership of Sponsor
          Stock, including, without limitation, any reports required under
          section 13 or 16 of the Securities Exchange Act of 1934, and shall
          immediately notify the Trustee in writing of any requirement to stop
          purchases or sales of Sponsor Stock pending the filing of any report.
          The Trustee shall provide to the Named Fiduciary such information on
          the Trust's ownership of Sponsor Stock as the Named Fiduciary may
          reasonably request in order to comply with Federal or state securities
          laws.

               (v)    Voting and Tender Offers.  Notwithstanding any other
          provision of this Agreement, the provisions of this Section shall
          govern the voting and tendering of

                                       4
<PAGE>
 
          Sponsor Stock.  The Sponsor, after consultation with the Trustee,
          shall provide and pay for all printing, mailing, tabulation and other
          costs associated with the voting and tendering of Sponsor Stock.

                      (A)  Voting.

                           (1)   When the issuer of the Sponsor Stock prepares
          for any annual or special meeting, the Sponsor shall notify the
          Trustee thirty (30) days in advance of the intended record date and
          shall cause a copy of all materials to be sent to the Trustee.  Based
          on these materials the Trustee shall prepare a voting instruction
          form.  At the time of mailing of notice of each annual or special
          stockholders' meeting of the issuer of the Sponsor Stock, the Sponsor
          shall cause a copy of the notice and all proxy solicitation materials
          to be sent to each Plan Participant with an interest in Sponsor Stock
          held in the Trust, together with the foregoing voting instruction form
          to be returned to the Trustee or its designee.  The form shall show
          the proportional interest in the number of full and fractional shares
          of Sponsor Stock credited to the Participant's accounts held in the
          Sponsor Stock Fund. The Sponsor shall provide the Trustee with a copy
          of any materials provided to the Participants and shall certify to the
          Trustee that the materials have been mailed or otherwise sent to
          Participants.

                           (2)   Each Participant with an interest in the
          Sponsor Stock Fund shall have the right to direct the Trustee as to
          the manner in which the Trustee is to vote (including not to vote)
          that number of shares of Sponsor Stock reflecting such Participant's
          proportional interest in the Sponsor Stock Fund (both vested and
          unvested).  Directions from a Participant to the Trustee concerning
          the voting of Sponsor Stock shall be communicated in writing, or by
          mailgram or similar means.  These directions shall be held in
          confidence by the Trustee and shall not be divulged to the Sponsor, or
          any officer or employee thereof, or any other person.  Upon its
          receipt of the directions, the Trustee shall vote the shares of
          Sponsor Stock reflecting the Participant's proportional interest in
          the Sponsor Stock Fund as directed by the Participant.  The Trustee
          shall not vote shares of Sponsor Stock reflecting a Participant's
          proportional interest in the Sponsor Stock Fund for which it has
          received no direction from the Participant.

                                       5
<PAGE>
 
                           (3)   The Trustee shall vote that number of shares of
          Sponsor Stock not credited to Participants' accounts in the same
          proportion on each issue as it votes those shares credited to
          particpants' accounts for which it received voting directions from
          Participants.

                      (B)  Tender Offers.

                           (1)   Upon commencement of a tender offer for any
          securities held in the Trust that are Sponsor Stock, the Sponsor shall
          notify each Plan Participant with an interest in such Sponsor Stock of
          the tender offer and utilize its best efforts to timely distribute or
          cause to be distributed to the Participant the same information that
          is distributed to shareholders of the issuer of Sponsor Stock in
          connection with the tender offer, and, after consulting with the
          Trustee, shall provide and pay for a means by which the Participant
          may direct the Trustee whether or not to tender the Sponsor Stock
          reflecting such Participant's proportional interest in the Sponsor
          Stock Fund (both vested and unvested).  The Sponsor shall provide the
          Trustee with a copy of any material provided to the Participants and
          shall certify to the Trustee that the materials have been mailed or
          otherwise sent to Participants.

                           (2)   Each Participant shall have the right to direct
          the Trustee to tender or not to tender some or all of the shares of
          Sponsor Stock reflecting such Participant's proportional interest in
          the Sponsor Stock Fund (both vested and unvested).  Directions from a
          Participant to the Trustee concerning the tender of Sponsor Stock
          shall be communicated in writing, or by mailgram or such similar means
          as is agreed upon by the Trustee and the Sponsor under the preceding
          paragraph.  These directions shall be held in confidence by the
          Trustee and shall not be divulged to the Sponsor, or any officer or
          employee thereof, or any other person except to the extent that the
          consequences of such directions are reflected in reports regularly
          communicated to any such persons in the ordinary course of the
          performance of the Trustee's services hereunder.  The Trustee shall
          tender or not tender shares of Sponsor Stock as directed by the
          Participant.  The Trustee shall not tender shares of Sponsor Stock
          reflecting a Participant's proportional interest in the Sponsor Stock
          Fund for which it has received no direction from the Participant.

                                       6
<PAGE>
 
                           (3)   The Trustee shall tender that number of shares
          of Sponsor Stock not credited to Participants' accounts in the same
          proportion as the total number of shares of Sponsor Stock credited to
          Participants' accounts for which it has received instructions from
          Participants.

                           (4)   A Participant who has directed the Trustee to
          tender some or all of the shares of Sponsor Stock reflecting the
          Participant's proportional interest in the Sponsor Stock Fund may, at
          any time prior to the tender offer withdrawal date, direct the Trustee
          to withdraw some or all of the tendered shares reflecting the
          Participant's proportional interest, and the Trustee shall withdraw
          the directed number of shares from the tender offer prior to the
          tender offer withdrawal deadline.  Prior to the withdrawal deadline,
          if any shares of Sponsor Stock not credited to Participants' accounts
          have been tendered, the Trustee shall redetermine the number of shares
          of Sponsor Stock that would be tendered under Section 4(g)(v)(B)(3) if
          the date of the foregoing withdrawal were the date of determination,
          and withdraw from the tender offer the number of shares of Sponsor
          Stock not credited to Participants' accounts necessary to reduce the
          amount of tendered Sponsor Stock not credited to Participants'
          accounts to the amount so redetermined.  A Participant shall not be
          limited as to the number of directions to tender or withdraw that the
          Participant may give to the Trustee.

                           (5)   A direction by a Participant to the Trustee to
          tender shares of Sponsor Stock reflecting the Participant's
          proportional interest in the Sponsor Stock Fund shall not be
          considered a written election under the Plan by the Participant to
          withdraw, or have distributed, any or all of his withdrawable shares.
          The Trustee shall credit to each proportional interest of the
          Participant from which the tendered shares were taken the proceeds
          received by the Trustee in exchange for the shares of Sponsor Stock
          tendered from that interest.  Pending receipt of directions (through
          the Administrator) from the Participant or the Named Fiduciary, as
          provided in the Plan, as to which of the remaining investment options
          the proceeds should be invested in, the Trustee shall invest the
          proceeds in the Mutual Fund described in Schedule "C".

               (vi)   Shares Credited.  For all purposes of this Section, the
          number of shares of Sponsor Stock deemed "credited" to a Participant's
          accounts as of the relevant date (the record date or the date
          specified in a tender offer) shall be calculated by reference to

                                       7
<PAGE>
 
          the number of shares reflected on the books of the transfer agent as
          of the relevant date.  In the case of a tender, the number of shares
          credited shall be determined as of a date as closely administratively
          feasible to the relevant date.  For all purposes of this Section, the
          number of shares of Sponsor Stock deemed "credited" or "reflected" to
          a Participant's proportional interest shall be determined as of the
          last preceding valuation date.  The trade date is the date the
          transaction is valued.


               (vii)  General.  With respect to all rights other than the right
          to vote, the right to tender, and the right to withdraw shares
          previously tendered, in the case of Sponsor Stock credited to a
          Participant's proportional interest in the Sponsor Stock Fund, the
          Trustee shall follow the directions of the Participant and if no such
          directions are received, the directions of the Named Fiduciary.  The
          Trustee shall have no duty to solicit directions from Participants.
          With respect to all rights other than the right to vote and the right
          to tender, in the case of Sponsor Stock not credited to Participants'
          accounts, the Trustee shall follow the directions of the Named
          Fiduciary.

               (viii) Conversion.  All provisions in this Section 4(g) shall
          also apply to any securities received as a result of a conversion of
          Sponsor Stock.

     (3)  Adding the following to the "investment options" portion of Schedules
          "A" and "C," respectively:

               Information Resources Stock Fund (Sponsor Stock Fund)


     (4)  Amending Schedule "B" by adding the following fee:

               Trustee Fee

                      To the extent that assets are invested in Sponsor Stock,
          .10% of such assets in the Trust payable pro rata quarterly on the
          basis of such assets as of the calendar quarter's last valuation date,
          with an annual minimum of $10,000 and an annual maximum of $35,000.


     (5)  Amending Schedule "C" by restating in its entirety the last sentence
          of said Schedule as follows:

          The mutual fund advised by Fidelity Management & Research Company
          referred to in Sections 4(c) and 4(g)(v)(B)(5) shall be Fidelity Money
          Market Trust: Retirement Money Market Portfolio.

                                       8
<PAGE>
 
     (6)  Amending Schedule "G" by adding the following at the end thereof:

                               SPONSOR STOCK FUND
                               ------------------

          EXCHANGES BETWEEN MUTUAL FUNDS AND THE SPONSOR STOCK FUND
          ---------------------------------------------------------

          Participants may call on any business day to exchange between the
          mutual funds and the Sponsor Stock Fund.  If the request is received
          before 4:00 p.m. (ET), it will receive that day's trade date.  Calls
          received after 4:00 p.m. (ET) will be processed on a next day basis.

          EXCHANGE RESTRICTIONS
          ---------------------

          Investments in the Sponsor Stock Fund will consist primarily of shares
          of Sponsor Stock.  However, in order to satisfy daily Participant
          requests for exchanges, loans and withdrawals, the Sponsor Stock Fund
          will also hold cash or other short-term liquid investments in an
          amount that has been agreed to in writing by the Sponsor and the
          Trustee.  The Trustee will be responsible for ensuring that the
          percentage of these investments falls within the agreed upon range
          over time.  However, if there is insufficient liquidity in the Sponsor
          Stock Fund to allow for such activity, the Trustee will sell shares of
          Sponsor Stock in the open market.  Exchange and redemption
