                         U.S. EXECUTIVE RETIREMENT PLAN

               As Amended and Restated Effective December 19, 2000

                                  INTRODUCTION

Effective as of July 25, 2000, the IMS Health Incorporated U.S. Executive
Retirement Plan (the "Plan") was established to provide a means of ensuring the
payment of a competitive level of retirement income and disability and survivor
benefits, and thereby attract, retain and motivate a select group of executives
of IMS Health Incorporated and its affiliated employers. This document
represents a complete restatement of the Plan effective as of December 19, 2000.

                            SECTION 1 - DEFINITIONS

1.1   "ACTUARIAL EQUIVALENT VALUE" shall mean a benefit of equivalent value
      computed on the basis of the 1983 Group Annuity Mortality Table and
      interest equal to the yield on 30-year Treasury Bonds as of the last
      business day of the Plan Year prior to the year in which the relevant
      calculation occurs.

1.2   "AFFILIATED EMPLOYER" shall mean an entity affiliated with the Company.

1.3   "AVERAGE FINAL COMPENSATION" shall mean a Member's average annual
      Compensation during the five consecutive 12-month periods in the last ten
      consecutive 12-month periods of his or her Service (or during the total
      number of consecutive 12-month periods if fewer than five), immediately
      prior to the month following the Member's termination
<PAGE>

of employment with the Company or an Affiliated Employer or, if earlier, removal
from participation under this Plan, affording the highest such Average Final
Compensation. If actual monthly Compensation for any month during the 120-month
computational period is unavailable, Compensation for such month shall be
determined by dividing the Member's annual rate of base pay in the month
preceding such unavailable month by 12.

1.4   "BASIC DISABILITY PLAN" shall mean as to any Member the long-term
      disability plan of the Company or an Affiliated Employer pursuant to which
      long-term disability benefits are payable to such Member.

1.5   "BASIC DISABILITY PLAN BENEFIT" shall mean the amount of benefits payable
      to a Member from the Basic Disability Plan.

1.6   "BASIC PLAN" shall mean as to any Member or Vested Former Member the
      defined benefit pension plan of the Company or an Affiliated Employer
      intended to meet the requirements of Code Section 401(a) pursuant to which
      retirement benefits are payable to such Member or Vested Former Member or
      to the Surviving Spouse or designated beneficiary of a deceased Member or
      Vested Former Member.

1.7   "BASIC PLAN BENEFIT" shall mean the amount of benefits payable from the
      Basic Plan to a Member or Vested Former Member.

                                      -2-
<PAGE>

1.8   "BOARD" shall mean the Board of Directors of IMS Health Incorporated,
      except that any action authorized to be taken by the Board hereunder may
      also be taken by a duly authorized committee of the Board or its duly
      authorized delegees.

1.9   "CAUSE". A Member shall not be deemed to have been terminated for
      "Cause" under this Plan unless such Member shall have been terminated
      for "Cause" under the terms of such Member's employment agreement with
      the Company, if any. If no such employment agreement containing a
      definition of "Cause" shall be in effect, for purposes or this Plan
      "Cause" shall mean a Member's:

      (a)   willful and continued failure to substantially perform his or her
            duties (other than any such failure resulting from incapacity due to
            physical or mental illness or Disability or any failure after the
            issuance of a notice of termination by the Member for Good Reason)
            which failure is demonstrably and materially damaging to the
            financial condition or reputation of the Company and/or its
            Affiliated Employers, and which failure continues more than 48 hours
            after a written demand for substantial performance is delivered to
            the Member by the Board, which demand specifically identifies the
            manner in which the Board believes that the Member has not
            substantially performed his or her duties; or

      (b)   the willful engaging by the Member in conduct which is demonstrably
            and materially injurious to the Company, monetarily or otherwise.

      No act, or failure to act, on the part of the Member shall be deemed
      "willful" unless done, or omitted to be done, by the Member not in good
      faith and without reasonable belief that his or her action or omission was
      in the best interest of the Company. Notwithstanding

                                      -3-

      the foregoing, the Member shall not be deemed to have been terminated for
      Cause unless and until there shall have been delivered to the Member a
      copy of the resolution duly adopted by the affirmative vote of not less
      than three-quarters (3/4) of the entire membership of the Board at a
      meeting of the Board (after reasonable notice to the Member and an
      opportunity for the Member, together with the Member's counsel, to be
      heard before the Board) finding that, in the good faith opinion of the
      Board, the Member was guilty of conduct set forth above in this definition
      and specifying the particulars thereof in detail.

      agreement with the Company, if any, a "Change in Control" shall be
      deemed to have occurred under this Plan, otherwise a "Change in

            fiduciary holding securities under an employee benefit plan of the
            Company, or any company owned, directly or indirectly, by the
            stockholders of the Company in substantially the same proportions as
            their ownership of stock of the Company), becomes the "Beneficial
            Owner" (as defined in Rule 13d-3 of the Exchange Act), directly or
            indirectly, of securities of the Company representing 20% or more of

            with the Company to effect a transaction described in Sections
            1.10(a), (c), or (d) hereof, (ii) a director nominated by any Person

            constitute a Change in Control, or (iii) a director nominated by any
            Person who is the Beneficial Owner, directly or indirectly, of
            securities of the Company representing 10% or more of the combined

            Board or nomination for election by the Company's stockholders was

            beginning of the period or whose election or nomination for election
            was previously so approved, cease for any reason to constitute at
            least a majority thereof;

      (c)   the stockholders of the Company approve any transaction or series of
            transactions under which the Company is merged or consolidated with

            would result in the voting securities of the Company outstanding
            immediately prior thereto continuing to represent (either by
            remaining outstanding or by being converted into voting securities
            of the surviving entity) more than 66 2/3% of the combined voting
            power of the voting securities of the Company or such surviving
            entity outstanding

                                      -5-

            then outstanding securities of the Company or such surviving entity;

      (d)   the stockholders of the Company approve a plan of complete
            liquidation of the Company or an agreement for the sale or
            disposition by the Company of all or substantially all of the
            Company's assets; or

            amount described in Section 3.7(b).

            Member's or Vested Former Member's lump sum benefit paid under this
            Plan to which such Member or Vested Former Member would not have
            been entitled, if such lump sum benefit had instead been payable in
            the form of an annuity under this Plan and such annuity payments
            were subject to the provisions of Section 3.5.

3.8   CHANGE IN CONTROL.

      (a)   Anything in this Plan to the contrary notwithstanding:

            (i)   Any Member who Retires at or within two years following a

                  Employer at or within two years following a Change in Control
                  for a reason other than Cause or whose employment is
                  voluntarily terminated by the Member with Good Reason at or
                  within two years following a Change in Control shall be deemed
                  to have completed three years of Service for purposes of
                  Sections 3.1(a) and 3.2(a) hereof and shall be credited with
                  three additional years of Service for purposes of calculating
                  the benefits payable under Sections 3.1(b) or 3.2(b) hereof,
                  as the case may be.

            (ii)  The benefits payable to any Member whose employment is
                  terminated at or within two years following a Change in
                  Control as provided in subsection (i) above shall be paid in
                  accordance with Section 3.3 hereof.

            (iii) In the event of a Potential Change in Control or Change in
                  Control, the Company shall, not later than 15 days thereafter,
                  have established one or more so-called "rabbi" trusts and
                  shall deposit therein cash in an amount sufficient to provide
                  for full payment of all potential benefits payable under the
                  Plan at or following a Change in Control. Such rabbi trust(s)
                  shall be irrevocable and shall provide that the Company may
                  not, directly or indirectly, use or recover any assets of the
                  trust(s) until such time as all obligations which potentially
                  could arise hereunder have been settled and paid in full,
                  subject only to the claims of creditors of the Company in the
                  event of insolvency or bankruptcy of the Company; provided,
                  however, that if no Change in Control has occurred within two
                  years after such

                                      -24-
<PAGE>

                  Potential Change in Control, such rabbi trust(s) shall at the
                  end of such two-year period become revocable and may
                  thereafter be revoked by the Company.

            (iv)  the provisions of Sections 3.5 through 3.7 shall be of no
                  force or effect with respect to Members who Retire or
                  terminate employment within a two-year period following a
                  Change in Control.

            has become Disabled shall be entitled to the Disability Benefit
            described in Section 4.1(b).

      (b)   AMOUNT. The Disability Benefit of a Member entitled thereto shall be
            an annual benefit payable in monthly installments under this Plan

            Covered Earnings, offset by the Member's (i) Basic Disability Plan
            Benefit, (ii) Basic Plan Benefit, if the Basic Disability Plan
            Benefit does not already include an offset for such Basic Plan
            Benefit, and (iii) Other Disability Income.

5.1   DEATH PRIOR TO BENEFIT COMMENCEMENT. Upon the death of a Member or Vested
      Former Member, prior to the commencement of his or her Retirement Benefit
      or Deferred Vested Benefit hereunder, any such Member shall be deemed to
      have completed three years of Service for purposes of Section 3.1(a) and
      Section 3.2(a) and his or her Surviving Spouse will be entitled to a
      Surviving Spouse's Benefit under this Plan equal to 50% of the Retirement
      or Deferred Vested Benefit that would have been provided from the Plan had
      the Member or Vested Member retired from or terminated employment with the
      Company or an Affiliated Employer on the date of death.

5.2   DEATH ON OR AFTER BENEFIT COMMENCEMENT. Upon the death of a Vested Former
      Member while he or she is receiving Retirement or Deferred Vested

      5.4, the Surviving Spouse's Benefit provided under Sections 5.1 or 5.2
      will be payable monthly, commencing on the first day of the month
      coincident with or next following the date of the Member's or Vested

                  Surviving Spouse dies.

5.4   LUMP SUM PAYMENT.

      (a)   If a Member or a Vested Former Member made an Election under Section
            3.4 but such Member or Vested Former Member died prior to such lump
            sum payment, the Surviving Spouse's Benefit payable under Section
            5.1 hereof will be payable in the form or combination of forms of
            payment so elected by such Member or Vested Former Member pursuant
            to such Lump Sum Election. The amount of any lump sum payment under
            the Plan shall be determined using the actuarial assumptions set
            forth in Section 3.4(a).

      (c)   Any Surviving Spouse's Benefit which is payable as a lump sum shall
            be paid within 60 days after the date when any portion of such
            benefit payable in annuity form commences or would commence if any
            portion of such Surviving Spouse's Benefit were payable as an
            annuity as set forth in Section 5.3.

                                      -27-
<PAGE>

5.5   REDUCTION. Notwithstanding the foregoing provisions of Section 5, the
      amount of a Surviving Spouse's Benefit shall be reduced by one percentage
      point for each year (where a half year or more is treated as a full year)
      in excess of ten years that the age of the Member or Vested Former Member
      exceeds the age of the Surviving Spouse.

                         SECTION 6 - PLAN ADMINISTRATOR

6.1   DUTIES AND AUTHORITY. The Plan Administrator shall be responsible for the
      administration of the Plan and may delegate to any management committee,
      employee, director or agent its responsibility to perform any act
      hereunder, including, without limitation, those matters involving the
      exercise of discretion; provided, that such delegation shall be subject to
      revocation at any time at the Plan Administrator's discretion. The Plan
      Administrator shall have the sole discretion to determine all questions
      arising in connection with the Plan, to interpret the provisions of the
      Plan and to construe all of its terms, to adopt, amend, and rescind rules
      and regulations for the administration of the Plan, and generally to
      conduct and administer the Plan and to make all determinations in
      connection with the Plan as may be necessary or advisable. All such
      actions of the Plan Administrator shall be conclusive and binding upon all
      Members, Former Members, Vested Former Members, Surviving Spouses and
      other persons.

6.2   CLAIMS PROCEDURE. A Member, Former Member or Vested Former Member or his
      or her authorized representative shall have 60 days after receipt of
      written notification of denial of a claim for benefits under the Plan to
      request a review of the denial by making written

                                      -28-
<PAGE>

      request to the Plan Administrator and may review pertinent documents and
      submit issues and comments in writing within such 60-day period.

      Not later than 60 days after receipt of the request for review, the Plan
      Administrator shall render and furnish to the claimant a written decision,
      which shall make specific references to pertinent Plan provisions on which
      it is based. If special circumstances require an extension of time for
      processing, the decision shall be rendered as soon as possible, but not
      later than 120 days after receipt of the request for review, provided that
      written notice and explanation of the delay are given to the claimant
      prior to commencement of the extension. Such decision by the Plan
      Administrator shall not be subject to further review. If a decision on
      review is not furnished to a claimant within the specified time period,
      the claim shall be deemed to have been denied on review.

                           SECTION 7 - MISCELLANEOUS

7.1   AMENDMENT; TERMINATION. The Board of Directors of the Company, may, in its
      sole discretion, terminate, suspend or amend this Plan at any time or from
      time to time, in whole or in part; provided, however, that no termination,
      suspension or amendment of the Plan may adversely affect (a) a Member's or
      Vested Former Member's benefit under the Plan to which he or she is
      entitled hereunder, or, (b) a Vested Former Member's right or the right of
      a Surviving Spouse to receive or to continue to receive a benefit in
      accordance with the Plan, such benefits or rights as in effect on the date
      immediately preceding the date of such termination, suspension or
      amendment. Notwithstanding the foregoing, the Employee Benefits Committee
      of the Company may amend the Plan

                                      -29-
<PAGE>

      without the approval of the Board of Directors of the Company with respect
      to amendments that such Committee determines do not have a significant
      effect on the cost of the Plan.

7.2   NO EMPLOYMENT RIGHTS. Nothing contained herein will confer upon any
      Member, Former Member or Vested Former Member the right to be retained in
      the service of the Company or any Affiliated Employee, nor will it
      interfere with the right of the Company or any Affiliated Employer to
      discharge or otherwise deal with Members, Former Members or Vested Former
      Members with respect to matters of employment.

7.3   PAYOUT IN DISCRETION OF THE PLAN ADMINISTRATOR. Notwithstanding anything

      Members and Surviving Spouses under the Plan, a lump sum distribution of a
      Member's, Vested Former Member's and/or Surviving Spouse's Retirement
      Benefit or Surviving Spouse's Benefit under the Plan in an amount equal to
      the Actuarial Equivalent Value of such Retirement Benefit or Surviving
      Spouse's Benefit, in full satisfaction of all present and future Plan
      liability with respect to such Member, Vested Former Member and/or
      Surviving Spouse, if the amount of such present value is less than
      $250,000. Such lump sum distribution may be made without the consent of
      the Member, Vested Former Member or Surviving Spouse.

7.4   UNFUNDED STATUS. Members and Vested Former Members shall have the status
      of general unsecured creditors of the Company, and this Plan constitutes a
      mere promise by the

                                      -30-
<PAGE>

      Company to make benefit payments at the time or times required hereunder.

      purposes and for purposes of Title I of ERISA and any trust created by the
      Company and any assets held by such trust to assist the Company in meeting
      its obligations under the Plan shall meet the requirements necessary to
      retain such unfunded status.

7.5   ARBITRATION. Any dispute or controversy arising under or in connection
      with the Plan shall be settled exclusively by arbitration in New York, New
      York in accordance with the rules of the American Arbitration Association

      entire costs of any proceeding brought by a Member, Vested Former Member,
      Former Member, or Surviving Spouse hereunder, including the fees and
      expenses of counsel and pension experts engaged by such person, and such
      expenses shall be reimbursed promptly upon evidence that such expenses
      have been incurred without awaiting the outcome of the proceedings;
      provided however, that such costs and expenses shall be repaid to the
      Company by the recipient of same if it is finally determined by the
      arbitrators that the position taken by such person was entirely without
      merit. Failure of such person to prevail in any dispute or controversy
      shall not be the sole basis on which such determination shall be made.

7.6   NO ALIENATION. A Member's or Vested Former Member's right to benefit
      payments under the Plan shall not be subject in any manner to
      anticipation, alienation, sale, transfer, assignment, pledge, encumbrance,
      attachment or garnishment by creditors or such Member or Vested Former
      Member or his or her Surviving Spouse.

                                      -31-

7.7   WITHHOLDING. The Company may withhold from any benefit under the Plan an
      amount sufficient to satisfy its tax withholding obligations.

7.8   GOVERNING LAW. The Plan shall be governed by and construed in accordance
      with the laws of the State of New York applicable to contracts made and to
      be performed in such state to the extent not preempted by federal law.

7.9   SUCCESSORS. The Company shall require any successor (whether direct or
      indirect, by purchase, merger, consolidation or otherwise) to all or
      substantially all of the business and/or assets of the Company to
      expressly assume and agree to perform the obligations of the Company under
      this Plan in the same manner and to the same extent that the Company would
      have been required to perform such obligations if no such succession had
      taken place and such assumption shall be an express condition to the
      consummation of any such purchase, merger, consolidation or other
      transaction.

7.10  INTEGRATION. In the event of any conflict or ambiguity between this
      Plan and the terms of any employment agreement between a Member and the
      Company or any Change in Control Agreement between a Member and the
      Company (this Plan and any such employment agreement or Change in
      Control Agreement being collectively referred to herein as the
      "arrangements"), such conflict or ambiguity shall be resolved in
      accordance with the terms of that arrangement which are most beneficial
      to the Member; provided, however, that no such resolution of any such
      conflict or ambiguity shall operate to cause the Member to receive
      duplicate payments or benefits under the arrangements.

            the extent he then holds those positions), shall cease to hold any
            other position he may hold within the Company and shall resign as a

                  Stock Incentive Plan (excluding all replacement options) and

                  terms provided in the original grants and the options awarded
                  in the August 23, 2000 grant shall be exercisable in
