         may from time to time change the designated Beneficiary or
         Beneficiaries by completing and filing a new designation in writing
         with the Committee. A change in beneficiary designation shall be deemed

         Participant's Disability or death, or the Participant's termination of
         employment following a Change of Control, as set forth in Sections
         4.02, 4.03 and 4.04, respectively), or (ii) at any time, whether before
         or after Participant has completed five (5) Years of Service with the

         breaches, during the period of his employment, any of his obligations

         reasonable period of time, but not later than 90 days after receipt of
         the claim, notify the claimant of the denial of the claim, unless the
         claimant receives written notice from the Committee prior to the end of
         the 90-day period stating that special circumstances require an


                                       4
<PAGE>

         extension (of up to 90 additional days) of the time for decision. Such
         notice of denial shall be in writing and shall contain:

         a)    The specific reason or reasons for the denial of the claim;

         b)    A reference to the relevant Plan provisions upon which the denial
               is based;

         c)    A description of any additional material or information necessary
               for the claimant to perfect the claim, together with an

         Directors requesting a review of the denial of the claim. Absent a
         request for review within the 60-day period, the claim shall be deemed
         to be conclusively denied. In connection with the claimant's appeal of
         the denial of his or her claim, he or she may review relevant documents
         and may submit issues and comments in writing. To provide for fair
         review and a full record, the claimant must submit in writing all
         facts, reasons and arguments in support of his or her position within
         the time allowed for filing a written request for review. All issues
         and matters not raised for review will be deemed waived by the
         claimant.

5.03     Decision Upon Review of a Denial of a Claim for Benefits. The Board of
         Directors shall render a review decision in writing within 60 days
         after receipt of the claimant's request for review, provided that, in
         special circumstances the Board may extend the time for decision by not
         more than 60 days upon written notice to the claimant. The claimant
         shall receive written notice of the Board's review decision, together
         with specific reasons for the decision and reference to the pertinent
         provisions of the Plan.

         The decision of the Committee shall be final and binding in all
         respects on the Company, the claimant and any other person claiming an
         interest in the Plan through or on behalf of the claimant. No
         litigation may be commenced by or on behalf of a claimant with respect
         to this Plan until after the claim and review process described in this
         Article V has been exhausted. Judicial review of Committee action shall
         be limited to whether the Committee acted in an arbitrary and
         capricious manner.

<PAGE>

         that of the Committee in which he or she participated); nor shall the

         the Plan accrued as of the date of such amendment or termination.

VIII.    MISCELLANEOUS

8.01     Separation of Plan; No Implied Rights. Neither the establishment of the
         Plan nor any amendment thereof shall be construed as giving the
         Participant, his Beneficiary, or any other person any legal or
         equitable right unless such right shall be specifically provided for in
         the Plan or conferred by specific action of the Company in accordance
         with the terms and provisions of the Plan. Except as expressly provided
         in this Plan, the Company shall not be required or be liable to make
         any payment under this Plan.

8.02     No Right to Company Assets. Neither the Participant nor any other
         person shall acquire by reason of the Plan any right in or title to any
         assets, funds or property of the Company whatsoever, including, without
         limiting the generality of the foregoing, any specific funds, assets or
         other property which the Company, in its sole discretion, may set aside
         in anticipation of a liability hereunder. Any benefits which become
         payable hereunder shall be paid from the general assets of the Company.
         The Participant (or his Beneficiary in the event of his death) is
         solely a general creditor of the Company and has only a contractual
         right to the amounts, if any, payable hereunder, unsecured by any asset
         of the Company. Nothing contained in the Plan constitutes a guarantee
         by the Company that the assets of the Company shall be sufficient to
         pay any benefits to any person.

8.03     No Employment Rights. Nothing herein shall constitute a contract of
         employment or of continuing service or in any manner obligate the
         Company to continue the services of the Participant, or obligate the
         Participant to continue in the service of the Company, or as a
         limitation of the right of the Company to discharge any of its
         employees, with or without cause.

8.04     Offset. If, at the time payment is to be made hereunder, the
         Participant or his Beneficiary is indebted or obligated to the Company,
         then the payment remaining to be made to the Participant or his
         Beneficiary may, at the discretion of the Company, be reduced by the
         amount of such indebtedness or obligation. However, an election by the
         Company not to reduce any such payment shall not constitute a waiver of
         its claim, or prohibit or otherwise impair the Company's


                                       7
<PAGE>

         right to offset future payment for such indebtedness or obligation.

8.05     Protective Provisions. In order to facilitate the payment of benefits
         hereunder, the Participant shall cooperate with the Company by
         furnishing any and all information requested by the Company, including
         taking such physical examinations as the Company may deem necessary,
         and taking such other actions as may be requested by the Company.

8.06     Non-assignability. Neither the Participant nor any other person shall
         have any voluntary or involuntary right to commute, sell, assign,
         pledge, anticipate, mortgage or otherwise encumber, transfer,
         hypothecate, or convey in advance of actual receipt the amounts, if
         any, payable hereunder, or any part thereof, which are expressly
         declared to be unassignable and non-transferable. No part of the
         benefit payable shall be, prior to actual payment, subject to seizure
         or sequestration for the payment of any debts, judgments, alimony or
         separate maintenance owed by the Participant or any other person, or be
         transferable by operation of law in the event of the Participant's or
         any other person's bankruptcy or insolvency.

8.07     Gender and Number. Wherever appropriate herein, the masculine may mean
         feminine and the singular may mean the plural, or vice versa.

8.08     Notice. Any notice required or permitted to be given under the Plan
         shall be sufficient if in writing and hand delivered, or sent by
         registered or certified mail, and if given to the Company, delivered to
         the principal office of the Company, directed to the attention of the
         Administrative Committee. Such notice shall be deemed given as of the
         date of delivery, or, if delivery is made by mail, as of the date shown
         on the postmark or the receipt for registration or certification.

8.09     Governing Laws. The Plan shall be construed and administered solely by
         rules of Federal law applicable to unfunded deferred compensation plans
         provided to a select group of management or highly compensated
         employees within the meaning of the applicable provisions of ERISA.

8.10     Unfunded Plan; Supplemental Executive Retirement Plan Trust. No funds
         shall be segregated or earmarked for any current or former Participant,
         Beneficiary or other person under the Plan. However, the Company may,
         but shall be under no obligation to, establish a Trust with (an)
         independent trustee(s), and shall comply with the terms of the Trust.
         The Company may transfer to the trustee(s) an amount of cash,
         marketable securities, or other property acceptable to the trustee(s)
         ("Trust Property") equal in value to all or a portion of the amount
         necessary, calculated in accordance with the terms of the Trust, to pay
         the Company's obligations under the Plan (the "Funding Amount"), and
         may make additional transfers to the trustee(s) as may be necessary in
         order to maintain the Funding Amount. Trust Property so transferred
         shall be held, managed, and disbursed by the trustee(s) in accordance
         with the terms of the Trust. To the extent that Trust Property shall be
         used to pay the Company's obligations under



                                       8

         the Plan, such payments shall discharge obligations of the Company;
         however, the Company shall continue to be liable for amounts not paid
         by the Trust. Trust Property will nevertheless be subject to claims of
         the Company's creditors in the event of bankruptcy or insolvency of
         the Company, and the Participant's rights under the Plan and Trust
         shall at all times be subject to the provisions of Section 8.02.

8.11     Incapacity of Recipient. If the Participant or Beneficiary is deemed by
         the Committee to be incapable of personally receiving and giving valid
         receipt of the payment of the Plan Benefit, then, unless and until
         claim therefore shall have been made by a duly appointed guardian or
         other legal representative of such person, the Company may provide for
         such payment or any part thereof to be made to any other person or
         institution then contributing toward or providing for the care and
         maintenance of such person. Any such payment shall be a payment for the
         account of such person and a complete discharge of any liability of the
         Company and the Plan therefore.

8.12     Unclaimed Benefit. Each Participant shall keep the Committee informed
         of his current address and the current address of his Beneficiary. The
         Committee shall not be obligated to search for the whereabouts of any
         person. If the location of a Participant is not made known to the
         Committee within three (3) years after the date on which payment of the
         Participant's Plan Benefit may first be made, payment may be made as
         though the Participant had died at the end of the three-year period.
         If, within one additional year after such three-year period has
         elapsed, or, within three years after the actual death of the
         Participant, the Committee is unable to locate the Beneficiary of the
         Participant, then the Company shall have no further obligation to pay
         any benefit hereunder to such Participant or Beneficiary or any other
         person and such benefit shall be irrevocably forfeited.

IN WITNESS WHEREOF, the Company has adopted the Information Resources, Inc.
Supplemental Executive Retirement Plan, effective as of November 1, 2002.
