Dear Sirs:

     Reference is made to (i) the Distribution Agreement (the "1996 Distribution
Agreement"), dated as of October 28, 1996, among Cognizant Corporation, which
has been renamed Nielsen Media Research, Inc. ("NMR"), The Dun & Bradstreet
Corporation, which has been renamed the R.H. Donnelley Corporation ("RHD") and
ACNielsen Corporation ("ACNielsen") and (ii) the letter of undertaking dated
June 29, 1998 from IMS Health Incorporated ("IMS HEALTH") to RHD and ACNielsen.
In June 1998, NMR distributed to its stockholders all of the outstanding shares
of common stock of IMS HEALTH (the "IMS HEALTH Distribution"). IMS HEALTH has
announced its intention to distribute (the "Gartner Distribution") to its
stockholders all of the shares of the Class B Common Stock of Gartner Group,
Inc. ("Gartner") that IMS HEALTH will hold following the recapitalization of
Gartner contemplated by the Merger Agreement dated June 17, 1999, between
Gartner and GRGI, INC. In connection with the IMS HEALTH Distribution, IMS
HEALTH undertook (the "IMS HEALTH Undertaking") to both RHD and ACNielsen to be
jointly and severally liable for all Cognizant Liabilities (as defined in the
1996 Distribution Agreement). Under Section 8.9(c) of the 1996 Distribution
Agreement, as applicable to IMS HEALTH pursuant to the IMS HEALTH Undertaking,
IMS HEALTH may not make a distribution such as the Gartner Distribution unless
it causes the distributed entity to undertake to both RHD and ACNielsen to be
jointly and severally liable for all Cognizant Liabilities under the 1996
Distribution Agreement. Therefore, in accordance with Section 8.9(c) of the 1996
Distribution Agreement and intending to be legally bound hereby, from and after
the effective time of the Gartner Distribution, Gartner undertakes to each of
RHD and ACNielsen to be jointly and severally liable for all Cognizant
Liabilities under the 1996 Distribution Agreement.

    Very truly yours,

    GARTNER GROUP, INC.

Distribution Agreement entered into between the Company and IMS HEALTH dated as

            SECTION I.1. The Merger. (a) Upon the terms and subject to the
conditions of this Agreement, at the Effective Time (as defined below), Merger
Sub shall be merged with and into the Company in accordance with the DGCL,
whereupon the separate corporate existence of Merger Sub shall cease, and the

            (b) Following satisfaction or waiver of all conditions to the
Merger, the Company and Merger Sub shall file a Certificate of Merger with the

            (c) At and after the Effective Time, the Merger shall have the
effects set forth in the DGCL. Without limiting the foregoing and subject
thereto, from and after the Effective Time, the Surviving Corporation shall

hereby;

            (b) each of the Contributed Shares shall automatically be canceled

            (c) each share of Class A Common Stock (other than shares to be
canceled in accordance with Section 1.2(b)) shall remain issued and outstanding
and not be affected by the Merger, except that all shares of Class A Common
Stock remaining outstanding at the Effective Time shall have the rights and
privileges as set forth in the Surviving Corporation Certificate of
Incorporation, as amended hereby; and



                                                                               3

privileges as set forth in the Surviving Corporation Certificate of

      Stock that remain issued and outstanding under Section 1.2(c) hereof or
      that remain treasury shares under Section 1.2(d) hereof shall not be
      exchanged and shall continue to represent an equal number of shares of
      Class A Common Stock of the Surviving Corporation without physical
      substitution of share certificates of the Surviving Corporation for
      existing share certificates of the Company.

            (b) Any dividend or other distribution declared or made with respect
to any shares of capital stock of the Company, whether the record date for such

                                   ARTICLE III

              COVENANTS AND REPRESENTATIONS AND WARRANTIES

            SECTION III.1. Stockholders Meeting. The Company shall, as soon as
practicable following the date of this Agreement, duly call, give notice of,
convene and hold, a meeting of its stockholders (the "Stockholders Meeting") for
the purpose of considering, as three separate proposals, (i) the approval of the
Merger and this Agreement which, subject to the Distribution Agreement, will
commit the Directors of the Company to authorize the Cash Dividend (as defined
in the Distribution Agreement) and Stock Repurchase (as defined in the
Distribution Agreement); (ii) the approval of amendments to the Company's
Certificate of Incorporation providing for the proposed classified board,
director removal and replacement and related provisions in Articles IV and V of
the Certificate of Incorporation of the Company as set forth in Exhibit A-1(a)
hereto to become effective solely upon effectiveness of the Merger (the
"Governance Provisions"); and (iii) the approval of amendments to the Company's
Certificate of Incorporation providing for the increase of authorized stock
which the Company may issue as set forth in Exhibits A-1(a) and A-1(b) hereto to
become effective solely upon the effectiveness of the Merger (the "Share
Increase"). The Company shall, through its Board of Directors, continue to
recommend to its stockholders approval of the Merger and this Agreement and
shall not withdraw such recommendation; provided, however, that the Company's
Board of Directors may withdraw such recommendation if it determines in good
faith, based upon the advice of outside counsel, that the Board will violate its
fiduciary duties to the stockholders of the Company if such recommendation is
not withdrawn.

            SECTION III.2. Filings; Other Actions. (a) Subject to the provisions
of this Agreement and the Distribution Agreement, the Company shall prepare and
file with the Securities and Exchange Commission (the "SEC") a proxy statement
for the solicitation of proxies in favor of (i) the approval and adoption of
this Agreement and the Merger, (ii) the approval of the Governance Provisions as
amendments to the Company's Certificate of Incorporation to become effective
solely upon the effectiveness of the Merger, and (iii) the approval of the Share
Increase as amendments to the Company's Certificate of Incorporation to become
effective solely upon the effectiveness of the Merger (the "Proxy Statement").
The Company shall not propose to its stockholders the adoption of the Governance
Provisions or the Share Increase as independent amendments to the Company's
Certificate of Incorporation, but only as amendments to become effective solely
upon the effectiveness of the Merger. The Company shall use all reasonable
efforts to have the Proxy Statement cleared by the SEC for mailing in definitive
form as promptly as practicable after such filing. The Company and IMS


                                                                               6


HEALTH shall cooperate with each other in the preparation of the Proxy Statement
and any amendment or supplement thereto, and the Company shall notify IMS HEALTH
of the receipt of any comments of the SEC with respect to the Proxy Statement
and of any requests by the SEC for any amendment or supplement thereto or for
additional information, and shall provide to IMS HEALTH promptly copies of all
correspondence between the SEC and the Company or any of its advisors with
respect to the Proxy Statement. The Company shall give IMS HEALTH and its
counsel appropriate advance opportunity to review the Proxy Statement and all
responses to requests for additional information by and replies to comments of
the SEC, and shall incorporate therein any reasonable comments IMS HEALTH may
deliver to the Company with respect thereto, before such Proxy Statement,
response or reply is filed with or sent to the SEC. The Company agrees to use
commercially reasonable efforts, after consultation with IMS HEALTH and its
advisors, to respond promptly to all such comments of, and requests by, the SEC
and to cause the Proxy Statement to be mailed to the holders of the Company's
common stock entitled to vote at the Stockholders Meeting as soon as reasonably
possible following the execution hereof. IMS HEALTH shall provide the Company
such information concerning the business and affairs of IMS HEALTH and Merger
Sub as is reasonably required for inclusion in the Proxy Statement.

            (b) Each of the Company and IMS HEALTH shall promptly, and in any
event within five business days after the execution and delivery of this
Agreement, make all filings or submissions as are required under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), and any other applicable law.

            (c) Each of the Company and IMS HEALTH agrees promptly to furnish to
the other all copies of written communications (and summaries of the substance
of all oral communications) received by it, or any of its affiliates or
representatives from, or delivered by any of the foregoing to, any federal,
state or local or international court, commission, governmental body, agency,
authority, tribunal, board or other governmental entity (each a "Governmental
Entity") in respect of the transactions contemplated hereby.

            (d) At the stockholders' meeting, IMS HEALTH agrees to vote, or
cause to be voted, all shares of Class A Common Stock of the Company owned by it
and any of its subsidiaries or affiliates in favor of the Merger, the other
transactions contemplated by this Agreement, the Governance Provisions and the
Share Increase.

            SECTION III.3. Reasonable Efforts. Upon the terms and subject to the
conditions set forth in this Agreement, each of the parties hereto agrees to use
commercially reasonable efforts to take, or cause to be taken, all actions, and
to do, or cause to be done, and to assist and cooperate with the other parties
in doing, all things necessary, proper or advisable to obtain the approval and
adoption of this Agreement by the stockholders of Gartner as contemplated by
Section 4.1(a) and Section 4.2(a) and to consummate, as soon as practicable
following such approval, the Merger and the other transactions contemplated by
this Agreement and the Distribution Agreement, including, but not limited to (i)

      (the "Class B Directors"). Each share of Class B Common Stock shall have
      one vote in the election of such directors. For purposes of this Section
      (b)(4) and Section (b) (5) of this Article IV, references to the
      authorized number of members of the Board of Directors (or the remaining
      directors) shall not include any directors which the holders of any shares
      of Preferred Stock may have the right to elect upon the failure of the
      Corporation to pay regular dividends on such Preferred Stock as and when
      due for a specified period of time. For purposes of this Section (b)(4),
      "Special Voting Rights" means the different voting rights of the holders
      of Class A Common Stock, holders of Class B Common Stock and holders of
      Voting Preferred Stock with respect to the election of the applicable
      percentage of the authorized number of members of the Board of Directors
      as described in this Section (b)(4)(A). "Voting Preferred Stock" means
      shares of each series of Preferred Stock upon which the right to vote for
      directors has been conferred in accordance with Section (c) of this
      Article IV, except for any right to elect directors which may be provided
      upon the failure of the Corporation to pay regular dividends on such
      Preferred Stock as and when due for a specified period of time.




                                                                               3

                  (B) Subject to the last sentence of this Section (b)(4)(B),
      notwithstanding anything to the contrary contained in Section (a)(4)(A) of
      this Article IV, for so long as any person or entity or group of persons
      or entities acting in concert beneficially own 15% or more of the
      outstanding shares of Class B Common Stock, then in any election of
      directors or other exercise of voting rights with respect to the election
      or removal of directors, such person, entity or group shall only be
      entitled to vote (or otherwise exercise voting rights with respect to) a
      number of shares of Class B Common Stock that constitutes a percentage of
      the total number of shares of Class B Common Stock then outstanding which
      is less than or equal to such person, entity or group's Entitled Voting
      Percentage. For the purposes hereof, a person, entity or group's "Entitled
      Voting Percentage" at any time shall mean the percentage of the then
      outstanding shares of Class A Common Stock beneficially owned by such
      person, entity or group at such time. For purposes of this Section
      (b)(4)(B), a "beneficial owner" of Common Stock includes any person or
      entity or group of persons or entities who, directly or indirectly,
      including through any contract, arrangement, understanding, relationship
      or otherwise, written or oral, formal or informal, control the voting
      power (which includes the power to vote or to direct the voting) of such
      Common Stock. The provisions of this Section (b)(4)(B) shall be effective
      only following (i) the distribution by IMS Health Incorporated ("IMS
      HEALTH") to its stockholders of all of the Class B Common Stock owned by
      it, (ii) the receipt of a private letter ruling from the Internal Revenue
      Service (the "IRS") to the effect that the terms of this Section (b)(4)(B)
      will not have any adverse effect on the private letter ruling issued by
      the IRS to IMS HEALTH on April 14, 1999 and any other private letter
      ruling issued by the IRS to IMS HEALTH or any predecessor or former parent
      of IMS HEALTH and (iii) the approval of the terms of this Section
      (b)(4)(B) by the New York Stock Exchange, Inc. or any other national
      securities exchange or automated quotation service on which the Common
      Stock is then listed or admitted for trading.

                  (C) Any Class A Director may be removed only for cause, by a
      vote of a majority of the votes held by the holders of Class A Common
      Stock and holders of Voting Preferred Stock, voting together as a class.
      Any Class B Director may be removed only for cause, by a vote of a
      majority of the votes held by the holders of Class B Common Stock, voting
      separately as a class.

                  (D) Except as otherwise specified herein, the holders of Class
      A Common Stock and holders of Class B Common Stock (i) shall in all
      matters not otherwise specified in this Section (b)(4) of this Article IV
      vote together (including, without limitation, with respect to increases or
      decreases in the authorized number of shares of any class of Common
      Stock), with each share of Class A Common Stock and Class B Common Stock
      having one vote, and (ii) shall be entitled to vote as separate classes
      only when required by law to do so under mandatory statutory provisions
      that may not be excluded or overridden by a provision in the Certificate
      of Incorporation or as provided herein.





                                                                               4

                  (E) Except as set forth in this Section (b)(4) of this Article
      IV, the holders of Class A Common Stock shall have exclusive voting power
      (except for any voting powers of any Preferred Stock) on all matters at
      any time when no Class B Common Stock is issued and outstanding, and the
      holders of Class B Common Stock shall have exclusive voting power (except
      for any voting powers of any Preferred Stock) on all matters at any time
      when no Class A Common Stock is issued and outstanding.

            (5) Vacancies; Increase or Decreases in Size of the Board of
      Directors. Any vacancy in the office of a director created by the death,
      resignation or removal of a director elected by (or appointed on behalf
      of) the holders of the Class B Common Stock or the holders of the Class A
      Common Stock and Voting Preferred Stock voting together as a class, as the
      case may be, may be filled by the vote of the majority of the directors
      (or the sole remaining director) elected by (or appointed on behalf of)
      such holders of Class B Common Stock or Class A Common Stock and Voting
      Preferred Stock (or on behalf of whom that director was appointed), as the
      case may be, whose death, resignation or removal created the vacancy,
      unless there are no such directors, in which case such vacancy may be
      filled by the vote of the majority of the directors or by the sole
      remaining director, regardless, in each instance, of any quorum
      requirements set out in the By-laws. Any director elected by some or all
      of the directors to fill a vacancy shall hold office for the remainder of
      the full term of the director whose vacancy is being filled and until such
      director's successor shall have been elected and qualified unless removed
      and replaced pursuant to Section (b)(4)(C) of this Article IV and this
      Section (b)(5). All newly-created directorships resulting from an increase
      in the authorized number of directors shall be allocated between Class A
      Directors and Class B Directors such that at all times the number of
      directorships reserved for Class A Directors shall be 20% of the
      authorized number of members of the Board of Directors (or, if such 20% is
      not a whole number, then the nearest lower whole number of directors that
      is closest to 20% of such membership) and the remaining directorships are
      reserved for Class B Directors. No decrease in the number of directors
      constituting the Board of Directors shall shorten the term of any
      incumbent director. If the number of directors is changed, any increase or
      decrease shall be apportioned among the classes of directors established
      pursuant to Article V so that the number of directors in each class is as
      nearly equal as possible.

            (6) Merger or Consolidation. In case of any consolidation of the
      Corporation with one or more other corporations or a merger of the
      Corporation with another corporation, each holder of a share of Class A
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class B Common Stock, and each holder of a share of Class B
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class A Common Stock; provided that, in any such
      transaction, the holders of shares of Class A Common Stock and the holders
      of shares of Class B Common Stock may receive different kinds of shares of
      stock if the only difference in such shares is the inclusion of voting
      rights which continue the Special Voting Rights.


                                                                               5

            (7) Liquidation. In the event of any liquidation, dissolution or
      winding up of the Corporation, the holders of the Class A Common Stock and
      Class B Common Stock shall participate equally per share in any
      distribution to stockholders, without distinction between classes.

                  (c) Preferred Stock. Any Preferred Stock not previously
      designated as to series may be issued from time to time in one or more
      series pursuant to a resolution or resolutions providing for such issue
      duly adopted by the Board of Directors (authority to do so being hereby
      expressly vested in the Board), and such resolution or resolutions shall
      also set forth the voting powers, full or limited or none, of each such
      series of Preferred Stock and shall fix the designations, preferences and
      relative, participating, optional or other special rights and
      qualifications, limitations or restrictions of each such series of
      Preferred Stock; provided that, except for any right to elect directors
      upon the failure of the Corporation to pay regular dividends on such
      Preferred Stock as and when due for a specified period of time, no series
      of Preferred Stock shall be entitled to vote generally in the election of
      any directors of the Corporation other than Class A Directors or to vote
      separately to elect one or more directors of the Corporation. The Board of
      Directors is authorized to alter the designation, rights, preferences,
      privileges and restrictions granted to or imposed upon any wholly unissued
      series of Preferred Stock and, within the limits and restrictions stated
      in any resolution or resolutions of the Board of Directors originally
      fixing the number of shares constituting any series of Preferred Stock, to
      increase or decrease (but not below the number of shares of any such
      series than outstanding) the number of shares of any such subsequent to
      the issue of shares of that series.

                  Each share of Preferred Stock issued by the Corporation, if
      reacquired by the Corporation (whether by redemption, repurchase,
      conversion to Common Stock or other means), shall upon such reacquisition
      resume the status of authorized and unissued shares of Preferred Stock,
      undesignated as to series and available for designation and issuance by
      the Corporation in accordance with the immediately preceding paragraph."

            The Existing Certificate of Incorporation shall be amended by
deleting in its entirety Article V thereof and replacing it with the following:

                                   "ARTICLE V

                  The directors, other than those who may be elected solely by
      the holders of any class or series of Preferred Stock, if any, shall be
      classified, with respect to the time for which they severally hold office,
      into three classes, as nearly equal in number as possible, as determined
      by the Board of Directors, one class ("Class I") to hold office initially
      for a term expiring at the first annual meeting of stockholders to be held
      after the date this Article V becomes effective (the "Classified Board
      Effective Date"), another class ("Class II") to hold office initially for
      a term expiring at the second annual meeting of stockholders to be held
      after the Classified Board Effective Date, and another class ("Class III")
      to hold office initially for a term expiring at the third annual meeting
      of


                                                                               6

      stockholders to be held after the Classified Board Effective Date, with
      the members of each class to hold office until their successors are
      elected and qualified. Directors elected by a class or series of stock, or
      if applicable, classes or series of stock voting together, shall be
      divided as evenly as possible, and shall be allocated by the Board of
      Directors, among Class I, Class II and Class III. At each annual meeting
      of stockholders, the successors of the class of directors whose term
      expires at that meeting shall be elected to hold office for a term
      expiring at the annual meeting of stockholders held in the third year
      following the year of their election."








                                                                  EXHIBIT A-1(B)

                    CERTIFICATE OF INCORPORATION AMENDMENTS
                         (WITHOUT GOVERNANCE PROVISIONS)

            The Certificate of Incorporation of the Company in effect
immediately prior to the Effective Time (the "Existing Certificate of
Incorporation") shall be amended by deleting in its entirety Article IV thereof
and replacing it with the following(1):

                                   "ARTICLE IV

                  (a) Authorized Stock. The Corporation is authorized to issue
      two classes of stock to be designated, respectively, "common stock" and
      "preferred stock." The total number of shares which this corporation is
      authorized to issue is two hundred four million, one hundred thousand
      (204,100,000) shares [two hundred fifty-five million (255,000,000)
      shares]*. Two hundred one million, six hundred thousand (201,600,000) [Two
      hundred fifty million (250,000,000)]* shares shall be designated common
      stock (the "Common Stock"), of which one hundred twenty million, nine
      hundred sixty thousand (120,960,000) [one hundred, sixty six million
      (166,000,000)]* shares shall be designated Class A Common Stock (the
      "Class A Common Stock") and eighty million, six hundred forty thousand
      (80,640,000) [eighty-four million (84,000,000)]* shares shall be
      designated Class B Common Stock (the "Class B Common Stock"). Two million,
      five hundred thousand (2,500,000) [Five million (5,000,000)]* shares shall
      be designated preferred stock (the "Preferred Stock"), all of which are
      presently undesignated as to series. Each share of Preferred Stock shall
      have a par value of $0.01 and each share of Common Stock shall have a par
      value of $0.0005.

                  (b) Common Stock. The Class A Common Stock and the Class B
      Common Stock shall be identical in all respects, except as otherwise
      expressly provided herein, and the relative powers, preferences, rights,
      qualifications, limitations and restrictions of the shares of Class A
      Common Stock and Class B Common Stock shall be as follows:


            (1) Cash or Property Dividends. Subject to the rights and
      preferences of the Preferred Stock as set forth in any resolution or
      resolutions of the Board of Directors providing for the issuance of such
      stock pursuant to this Article IV, and except as otherwise provided for
      herein, the holders of Class A Common Stock and Class B

- - -----------------
1  The amount of shares designated by an asterisk ("*") in Section (a) of
   Article IV will be in effect in lieu of the number of shares appearing
   immediately prior to such bracketed number bearing an asterisk if the Share
   Increase is approved in accordance with the terms of the Agreement and Plan
   of Merger.



                                                                               2

      Common Stock are entitled to receive dividends out of assets legally
      available therefor at such times and in such per share amounts as the
      Board of Directors may from time to time determine; provided that whenever
      a cash dividend is paid, the same amount shall be paid in respect of each
      outstanding share of Class A Common Stock and Class B Common Stock.

            (2) Stock Dividends. If at any time a dividend is to be paid in
      shares of Class A Common Stock or shares of Class B Common Stock (a "stock
      dividend"), such stock dividend may be declared and paid only as follows:
      only Class A Common Stock may be paid to holders of Class A Common Stock
      and only Class B Common Stock may be paid to holders of Class B Common
      Stock, and whenever a stock dividend is paid, the same rate or ratio of
      shares shall be paid in respect of each outstanding share of Class A
      Common Stock and Class B Common Stock.

            (3) Stock Subdivisions and Combinations. The corporation shall not
      subdivide, reclassify or combine stock of either class of Common Stock
      without at the same time making a proportionate subdivision or combination
      of the other class.

            (4) Voting. Voting power shall be divided between the classes and
      series of stock as follows:

                  (A) With respect to the election of directors, holders of
      Class A Common Stock and holders of Voting Preferred Stock (as defined
      below), voting together, shall be entitled to elect that number of
      directors which constitutes 20% of the authorized number of members of the
      Board of Directors (or, if such 20% is not a whole number, then the
      nearest lower whole number of directors that is closest to 20% of such
      membership) (the "Class A Directors"). Each share of Class A Common Stock
      shall have one vote in the election of the Class A Directors and each
      share of Voting Preferred Stock shall have a number of votes in the
      election of the Class A Directors as specified in the resolution of the
      Board of Directors authorizing such Voting Preferred Stock. Holders of
      Class B Common Stock shall be entitled to elect the remaining directors
      (the "Class B Directors"). Each share of Class B Common Stock shall have
      one vote in the election of such directors. For purposes of this Section
      (b)(4) and Section (b) (5) of this Article IV, references to the
      authorized number of members of the Board of Directors (or the remaining
      directors) shall not include any directors which the holders of any shares
      of Preferred Stock may have the right to elect upon the failure of the
      Corporation to pay regular dividends on such Preferred Stock as and when
      due for a specified period of time. For purposes of this Section (b)(4),
      "Special Voting Rights" means the different voting rights of the holders
      of Class A Common Stock, holders of Class B Common Stock and holders of
      Voting Preferred Stock with respect to the election of the applicable
      percentage of the authorized number of members of the Board of Directors
      as described in this Section (b)(4)(A). "Voting Preferred Stock" means
      shares of each series of Preferred Stock upon which the right to vote for
      directors has been conferred in accordance with Section (c) of this
      Article IV, except for any right to elect directors which may be provided
      upon the failure of the Corporation to pay regular dividends on such
      Preferred Stock as and when due for a specified period of time.







                                                                               3


                  (B) Subject to the last sentence of this Section (b)(4)(B),
      notwithstanding anything to the contrary contained in Section (a)(4)(A) of
      this Article IV, for so long as any person or entity or group of persons
      or entities acting in concert beneficially own 15% or more of the
      outstanding shares of Class B Common Stock, then in any election of
      directors or other exercise of voting rights with respect to the election
      or removal of directors, such person, entity or group shall only be
      entitled to vote (or otherwise exercise voting rights with respect to) a
      number of shares of Class B Common Stock that constitutes a percentage of
      the total number of shares of Class B Common Stock then outstanding which
      is less than or equal to such person, entity or group's Entitled Voting
      Percentage. For the purposes hereof, a person, entity or group's "Entitled
      Voting Percentage" at any time shall mean the percentage of the then
      outstanding shares of Class A Common Stock beneficially owned by such
      person, entity or group at such time. For purposes of this Section
      (b)(4)(B), a "beneficial owner" of Common Stock includes any person or
      entity or group of persons or entities who, directly or indirectly,
      including through any contract, arrangement, understanding, relationship
      or otherwise, written or oral, formal or informal, control the voting
      power (which includes the power to vote or to direct the voting) of such
      Common Stock. The provisions of this Section (b)(4)(B) shall be effective
      only following (i) the distribution by IMS Health Incorporated ("IMS
      HEALTH") to its stockholders of all of the Class B Common Stock owned by
      it, (ii) the receipt of a private letter ruling from the Internal Revenue
      Service (the "IRS") to the effect that the terms of this Section (b)(4)(B)
      will not have any adverse effect on the private letter ruling issued by
      the IRS to IMS HEALTH on April 14, 1999 and any other private letter
      ruling issued by the IRS to IMS HEALTH or any predecessor or former parent
      of IMS HEALTH and (iii) the approval of the terms of this Section
      (b)(4)(B) by the New York Stock Exchange, Inc. or any other national
      securities exchange or automated quotation service on which the Common
      Stock is then listed or admitted for trading.

                  (C) Any Class A Director may be removed, with or without
      cause, by a vote of a majority of the votes held by the holders of Class A
      Common Stock and holders of Voting Preferred Stock, voting together as a
      class. Any Class B Director may be removed, with or without cause, by a
      vote of a majority of the votes held by the holders of Class B Common
      Stock, voting separately as a class.

                  (D) Except as otherwise specified herein, the holders of Class
      A Common Stock and holders of Class B Common Stock (i) shall in all
      matters not otherwise specified in this Section (b)(4) of this Article IV
      vote together (including, without limitation, with respect to increases or
      decreases in the authorized number of shares of any class of Common
      Stock), with each share of Class A Common Stock and Class B Common Stock
      having one vote, and (ii) shall be entitled to vote as separate classes
      only when required by law to do so under mandatory statutory provisions
      that may not be excluded or overridden by a provision in the Certificate
      of Incorporation or as provided herein.

                  (E) Except as set forth in this Section (b)(4) of this Article
      IV, the holders of Class A Common Stock shall have exclusive voting power
      (except for any voting




                                                                               4

      powers of any Preferred Stock) on all matters at any time when no Class B
      Common Stock is issued and outstanding, and the holders of Class B Common
      Stock shall have exclusive voting power (except for any voting powers of
      any Preferred Stock) on all matters at any time when no Class A Common
      Stock is issued and outstanding.

            (5) Increase or Decreases in Size of the Board of Directors. All
      newly-created directorships resulting from an increase in the authorized
      number of directors shall be allocated between Class A Directors and Class
      B Directors such that at all times the number of directorships reserved
      for Class A Directors shall be 20% of the authorized number of members of
      the Board of Directors (or, if such 20% is not a whole number, then the
      nearest lower whole number of directors that is closest to 20% of such
      membership) and the remaining directorships are reserved for Class B
      Directors. No decrease in the number of directors constituting the Board
      of Directors shall shorten the term of any incumbent director.

            (6) Merger or Consolidation. In case of any consolidation of the
      Corporation with one or more other corporations or a merger of the
      Corporation with another corporation, each holder of a share of Class A
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class B Common Stock, and each holder of a share of Class B
      Common Stock shall be entitled to receive with respect to such share the
      same kind and amount of shares of stock and other securities and property
      (including cash) receivable upon such consolidation or merger by a holder
      of a share of Class A Common Stock; provided that, in any such
      transaction, the holders of shares of Class A Common Stock and the holders
      of shares of Class B Common Stock may receive different kinds of shares of

      winding up of the Corporation, the holders of the Class A Common Stock and

      duly adopted by the Board of Directors (authority to do so being hereby
      expressly vested in the Board), and such resolution or resolutions shall
      also set forth the voting powers, full or limited or none, of each such
      series of Preferred Stock and shall fix the designations, preferences and
      relative, participating, optional or other special rights and
      qualifications, limitations or restrictions of each such series of
      Preferred Stock; provided that, except for any right to elect directors

      of Preferred Stock shall be entitled to vote generally in the election of
      any directors of the Corporation other than Class A Directors or to vote
      separately to elect one or more directors of the Corporation. The Board of




                                                                               5

      Directors is authorized to alter the designation, rights, preferences,
      privileges and restrictions granted to or imposed upon any wholly unissued
      series of Preferred Stock and, within the limits and restrictions stated
      in any resolution or resolutions of the Board of Directors originally
      fixing the number of shares constituting any series of Preferred Stock, to
      increase or decrease (but not below the number of shares of any such
      series than outstanding) the number of shares of any such subsequent to
      the issue of shares of that series.

                  Each share of Preferred Stock issued by the Corporation, if
      reacquired by the Corporation (whether by redemption, repurchase,
      conversion to Common Stock or other means), shall upon such reacquisition
      resume the status of authorized and unissued shares of Preferred Stock,
      undesignated as to series and available for designation and issuance by
      the Corporation in accordance with the immediately preceding paragraph."

               Cognizant are distributed to the holders of record of shares of
               Cognizant.

          (y)  Stock Appreciation Right: A stock appreciation right granted
               pursuant to Section 8 of the Plan.

          (z)  Subsidiary: A subsidiary corporation, as defined in Section
               424(f) of the Code (or any successor section thereto).

3.   SHARES SUBJECT TO THE PLAN

     (a) Aggregate Share Limitations. Subject to adjustment as provided in
Section 10(a), the total number of Shares which may be issued and/or delivered
under the Plan is 13,000,000 plus the number of Shares reserved for awards under
the IMS Health Incorporated Replacement Plan for Certain Employees Holding
Cognizant Corporation Equity-Based Awards (the "Replacement Plan") that are not
in fact issued or delivered in connection with such awards; provided however,
that in no event may more than 1,000,000 shares be issued as restricted stock or
similar Awards. The Shares may consist, in whole or in part, of authorized and
unissued Shares or treasury Shares. Shares subject to an Award under the Plan
that is canceled, expired, forfeited, settled in cash, or otherwise terminated
without a delivery of Shares to the Participant (or a Beneficiary), including
the number of Shares withheld or surrendered in payment of

                                       4





any exercise or purchase price of an Award or taxes relating to an Award, will
become available for Awards under the Plan, and Shares shall be counted as
issued or delivered under the Replacement Plan in a manner consistent with the
counting of Shares under this Section 3. In addition, in the case of any Award
granted in substitution for awards of a company or business acquired by the
Company or a Subsidiary, Shares issued or issuable in connection with such
substitute Award shall not be counted against the number of Shares reserved
under the Plan, but shall be deemed to be available under the Plan by virtue of
the Company's assumption of the plan or arrangement of the acquired company or
business.

     (b) Annual Per-Person Limitations. In each calendar year during any part of
which the Plan is in effect, a Participant may be granted Awards under each of
Section 7, Section 8, and Section 9(b) relating to up to the Participant's
Annual Limit (such Annual Limit to apply separately to each Section). A
Participant's Annual Limit, in any year during any part of which the Participant
is then eligible under the Plan, shall equal 1,000,000 shares plus the amount of
the Participant's unused Annual Limit as of the close of the previous year,
subject to adjustment as provided in Section 10(a).

4.   ADMINISTRATION

     (a) The Plan shall be administered by the Committee, which may delegate its
duties and powers in whole or in part to any subcommittee thereof consisting
solely of at least two individuals who are each "non-employee directors" within
the meaning of Rule 16b-3 under the Act (or any successor rule thereto) and
"outside directors" within the meaning of Section 162(m) of the Code (or any
successor section thereto). The Committee is authorized to interpret the Plan,
to establish, amend and rescind any rules and regulations relating to the Plan,
and to make any other determinations that it deems necessary or desirable for
the administration of the Plan. The Committee may correct any defect or supply
any omission or reconcile any inconsistency in the Plan in the manner and to the
extent the Committee deems necessary or desirable. Any decision of the Committee
in the interpretation and administration of the Plan, as described herein, shall
lie within its sole and absolute discretion and shall be final, conclusive and
binding on all parties concerned (including, but not limited to, Participants
and their beneficiaries or successors). The Committee shall require payment of
any amount it may determine to be necessary to withhold for minimum statutory
withholding requirements for federal, state, local or other taxes as a result of
the exercise or settlement of an Award. Unless the Committee specifies
otherwise, the Participant may elect to pay a portion or all of such withholding
taxes by (a) delivery in shares or (b) having shares withheld by the Company
from any shares that would have otherwise been received by the Participant. No
authority to withhold shares is conferred under the Plan to the extent that,
solely due to such authority, an Award would be accounted for as a "variable"
award under APB 25. The Committee may, in its discretion, grant Awards either
alone or in addition to, in tandem with, or in substitution or exchange for, any
other Award or any award granted under another plan of the Company, any
subsidiary, or any business entity to be acquired by the Company or a
subsidiary, or any other right of a Participant to receive payment from the
Company or any subsidiary. If the chief executive officer of the Company is a
member of the Board, the Board by specific resolution may constitute such chief
executive officer as a committee of one which shall have the authority to grant
Awards of up to an aggregate of 50,000 Shares in each calendar year to each
Participant who is not subject to the rules promulgated under Section 16 of the
Act (or any successor section thereto);

                                       5




provided, however, that such chief executive officer shall notify the Committee
of any such grants made pursuant to this Section 4.

     (b) Without the prior approval of the Company's stockholders, Options
granted under the Plan will not be repriced, replaced or regranted through
cancellation, or by lowering the Option exercise price of a previously granted
Option.

5.   ELIGIBILITY

     Employees (but not members of the Committee or any person who serves only
as a director) of the Company and its Subsidiaries are eligible to be granted
Awards. In addition, any person who has been offered employment by the Company
or a Subsidiary is eligible to be granted Awards, provided that no such person
may receive any payment or exercise any right relating to an Award until such
person has commenced such employment. Participants shall be selected from time
to time by the Committee, in its sole discretion, from among those eligible, and
the Committee shall determine, in its sole discretion, the number of Shares to
be covered by the Awards granted to each Participant.

6.   LIMITATIONS

     No Award may be granted under the Plan after the tenth anniversary of the
Effective Date, but Awards theretofore granted may extend beyond that date.

7.   TERMS AND CONDITIONS OF OPTIONS

     Options granted under the Plan shall be, as determined by the Committee,
non-qualified, incentive or other stock options for federal income tax purposes,
as evidenced by the related Award agreements, and shall be subject to the
foregoing and the following terms and conditions and to such other terms and
conditions, not inconsistent therewith, as the Committee shall determine:

          (a) Option Price. The Option Price per Share shall be determined by
     the Committee, but shall not be less than 100% of the Fair Market Value of
     the Shares on the date an Option is granted. The Committee may require the
     Participant to pay a portion of the Option Price at the time of grant of
     the option, with the remainder of the Option Price payable upon exercise of
     the Option. Such prepayment of the Option Price shall be non-refundable
     except to the extent set forth in a Participant's original option
     agreement.

          (b) Exercisability. Options granted under the Plan shall be
     exercisable at such time and upon such terms and conditions as may be
     determined by the Committee, but in no event shall an Option be exercisable
     more than ten years after the date it is granted.

          (c) Exercise of Options. Except as otherwise provided in the Plan or
     in an Award agreement, an Option may be exercised for all, or from time to
     time any part, of the Shares for which it is then exercisable. For purposes
     of Section 7 of the Plan, the exercise date of an Option shall be the later
     of the date a notice of exercise is received by the Company and, if
     applicable, (A) the date payment is received by the Company pursuant to
     clauses (i), (ii) or (iii) in the following sentence, or (B) the date of
     sale by a broker of all or a portion of the Shares being purchased pursuant
     to clause (iv)

                                       6




     in the following sentence. Unless otherwise determined by the Committee,
     the Option Price for the Shares as to which an Option is exercised shall be
     paid to the Company in full not later than the time of exercise at the
     election of the Participant (i) in cash, (ii) in Shares having a Fair
     Market Value equal to the aggregate unpaid Option Price for the Shares
     being purchased and satisfying such other requirements as may be imposed by
     the Committee, (iii) partly in cash and partly in such Shares, or (iv)
     through the delivery of irrevocable instructions to a broker to deliver
     promptly to the Company an amount equal to the aggregate Option Price for
     the Shares being purchased. The Award agreement shall, unless otherwise
     provided by the Committee, permit the Participant to elect, subject to such
     terms and conditions as the Committee shall determine, to have the number
     of Shares deliverable to the Participant as a result of the exercise
     reduced by a number sufficient to pay the amount the Company determines to
     be necessary to withhold for federal, state, local or other taxes as a
     result of the exercise of the Option. No Participant shall have any rights
     to dividends or other rights of a stockholder with respect to Shares
     subject to an Option until the Participant has given written notice of
     exercise of the Option, paid in full for such Shares and, if applicable,
     has satisfied any other conditions imposed by the Committee pursuant to the
     Plan.

          (d) Restrictions on Shares Issued Upon Exercise; Other Conditions. If
     and to the extent so determined by the Committee, Shares issued upon
     exercise of an Option may be subject to limitations on transferability,
     risks of forfeiture, deferral of delivery, or such other terms and
     conditions as the Committee may impose, subject to Section 14(b). Such
     terms and conditions may include required forfeiture of Options or gains
     realized upon exercise thereof, for a specified period after exercise, in
     the event the Participant fails to comply with conditions relating to
     non-competition, non-disclosure, non-solicitation or non-interference with
     employees, suppliers, or customers, and non-disparagement and other
     conditions specified by the Committee.

            (e) Exercisability Upon Termination of Employment by Death or
Disability. If a Participant's employment with the Company and its Subsidiaries
terminates by reason by death or Disability after the date of grant of an
Option, (i) the unexercised portion of such Option shall immediately vest in
full (i.e., become non-forfeitable) and (ii) such portion may thereafter be
exercised during the shorter of (A) the remaining stated term of the Option or
(B) five years after the date of death or Disability.

            (f) Exercisability Upon Termination of Employment by Retirement. If
a Participant's employment with the Company and its Subsidiaries terminates by
reason of Retirement after the date of grant of an Option, the Participant's
unexercised Option may thereafter be exercised only during the period ending at
the earlier of five years after such Retirement or the stated expiration date of
such Option (the "Post-Retirement Exercise Period"), provided that such Option
shall be exercisable during such Post-Retirement Exercise Period only to the
extent such Option was exercisable at the time of such Retirement. The foregoing
notwithstanding, (i) the Committee may, in its sole discretion, accelerate the
vesting of the unvested portion of such Option held by a Participant upon such
Participant's Retirement, in which case such Option shall not be forfeited as
provided herein but thereafter shall become exercisable to the extent and at
such times as such portion of the Option would have become both vested and
exercisable during the Post-Retirement Exercise Period had the Participant's
employment not been terminated, unless the Committee specifies otherwise; and
(ii), if a Participant dies within a period of five years after such Retirement,
the Participant's unexercised Option (to the extent not previously forfeited)
may thereafter be exercised during the shorter of (i) the remaining stated term
of the Option or (ii) the period that is

                                       7




the longer of (A) five years after the date of such termination of employment or
(B) one year after the date of death.

     (g) Effect of Other Termination of Employment. If a Participant's
employment with the Company and its Subsidiaries terminates for any reason other
than death, Disability or Retirement after the date of grant of an Option as
described above, the Participant's unexercised Option may thereafter be
exercised during the period ending 90 days after the date of such termination of
employment, but only to the extent such Option was exercisable at the time of
such termination of employment, and in no event may such Option be exercised
after its stated expiration date. The foregoing notwithstanding, the Committee
may, in its sole discretion, accelerate the vesting of unvested Options held by
a Participant if such Participant is terminated from employment without "cause"
(as such term is defined by the Committee in its sole discretion) by the
Company.

8.   TERMS AND CONDITIONS OF STOCK APPRECIATION RIGHTS

     (a) Grants. The Committee also may grant (i) a Stock Appreciation Right
independent of an Option or (ii) a Stock Appreciation Right in connection with
an Option, or a portion thereof. A Stock Appreciation Right granted pursuant to
clause (ii) of the preceding sentence (A) may be granted at the time the related
Option is granted or at any time prior to the exercise or cancellation of the
related Option, (B) shall cover the same Shares covered by an Option (or such
lesser number of Shares as the Committee may determine) and (C) shall be subject
to the same terms and conditions as such Option except for such additional
limitations as are contemplated by this Section 8 (or such additional
limitations as may be included in an Award agreement).

     (b) Terms. The exercise price per Share of a Stock Appreciation Right shall
be an amount determined by the Committee but in no event shall such amount be
less than the greater of (i) the Fair Market Value of a Share on the date the
Stock Appreciation Right is granted or, in the case of a Stock Appreciation
Right granted in conjunction with an Option, or a portion thereof, the Option
Price of the related Option and (ii) an amount permitted by applicable laws,
rules, by-laws or policies of regulatory authorities or stock exchanges. Each
Stock Appreciation Right granted independent of an Option shall entitle a
Participant upon exercise to an amount equal to (i) the excess of (A) the Fair
Market Value on the exercise date of one Share over (B) the exercise price per
Share, times (ii) the number of Shares covered by the Stock Appreciation Right.
Each Stock Appreciation Right granted in conjunction with an Option, or a
portion thereof, shall entitle a Participant to surrender to the Company the
unexercised Option, or any portion thereof, and to receive from the Company in
exchange therefor an amount equal to (i) the excess of (A) the Fair Market Value
on the exercise date of one Share over (B) the Option Price per Share, times
(ii) the number of Shares covered by the Option, or portion thereof, which is
surrendered. The date a notice of exercise is received by the Company shall be
the exercise date. Payment shall be made in Shares or in cash, or partly in
Shares and partly in cash, valued at such Fair Market Value, all as shall be
determined by the Committee. Stock Appreciation Rights may be exercised from
time to time upon actual receipt by the Company of written notice of exercise
stating the number of Shares subject to an exercisable Option with respect to
which the Stock Appreciation Right is being exercised. No fractional Shares will
be issued in payment for Stock Appreciation Rights, but instead cash will be
paid for a fraction or, if the Committee should so determine, the number of
Shares will be rounded downward to the next whole Share.

                                       8





     (c) Limitations. The Committee may impose, in its discretion, such
conditions upon the exercisability or transferability of Stock Appreciation
Rights as it may deem fit.

     (d) Limited Stock Appreciation Rights. The Committee may grant LSARs that
are exercisable upon the occurrence of specified contingent events. Such LSARs
may provide for a different method of determining appreciation, may specify that
payment will be made only in cash and may provide that any related Awards are
not exercisable while such LSARs are exercisable. Unless the context otherwise
requires, whenever the term "Stock Appreciation Right" is used in the Plan, such
term shall include LSARs.

9.   OTHER STOCK-BASED AWARDS

     (a) Generally. The Committee, in its sole discretion, may grant Awards of
Shares, Awards of restricted Shares and Awards that are valued in whole or in
part by reference to, or are otherwise based on the Fair Market Value of, Shares
("Other Stock-Based Awards"). Such Other Stock-Based Awards shall be in such
form, and dependent on such conditions, as the Committee shall determine,
including, without limitation, the right to receive one or more Shares (or the
equivalent cash value of such Shares) as an outright bonus or upon the
completion of a specified period of service, the occurrence of an event and/or
the attainment of performance objectives. Other Stock-Based Awards may be
granted alone or in addition to any other Awards granted under the Plan. Subject
to the provisions of the Plan, the Committee shall determine to whom and when
Other Stock-Based Awards will be made, the number of Shares to be awarded under
(or otherwise related to) such Other Stock-Based Awards; whether such Other
Stock-Based Awards shall be settled in cash, Shares or a combination of cash and
Shares; and all other terms and conditions of such Awards (including, without
limitation, the vesting provisions thereof). Cash awards, as an element of or
supplement to any other Award under the Plan, may also be granted pursuant to
this Section 9(a). In addition, the Committee is authorized to grant dividend
equivalents to a Participant, entitling the Participant to receive cash, Shares,
other Awards, or other property equal in value to dividends paid with respect to
a specified number of Shares, or other periodic payments. Dividend equivalents
may be awarded on a free-standing basis or in connection with another Award. The
Committee may provide that Dividend Equivalents shall be paid or distributed
when accrued or shall be deemed to have been reinvested in additional Shares,
Awards, or other investment vehicles, subject to such restrictions on
transferability and risks of forfeiture as the Committee may specify.

     (b) Performance-Based Awards. Notwithstanding anything to the contrary
herein, certain Other Stock-Based Awards granted under this Section 9 may be
granted in a manner which is deductible by the Company without limitation under
Section 162(m) of the Code (or any successor section thereto)
("Performance-Based Awards"). A Participant's Performance-Based Award shall be
determined based on the attainment of written performance goals approved by the
Committee for a performance period established by the Committee (i) while the
outcome for that performance period is substantially uncertain and (ii) no more
than 90 days after the commencement of the performance period to which the
performance goal relates or, if less, the number of days which is equal to 25
percent of the relevant performance period. The performance goals, which must be
objective, shall be based upon one or more of the following criteria: (i)
consolidated earnings before or after taxes (including earnings before


                                       9




interest, taxes, depreciation and amortization); (ii) net income; (iii)
operating income; (iv) earnings per share; (v) book value per share; (vi) return
on stockholders' equity; (vii) expense management; (viii) return on investment;
(ix) improvements in capital structure; (x) profitability of an identifiable
business unit or product; (xi) maintenance or improvement of profit margins;
(xii) stock price; (xiii) market share; (xiv) revenues or sales; (xv) costs;
(xvi) cash flow; (xvii) working capital; (xviii) economic value added; (xix)
return on assets; (xx) total stockholder return (stock price appreciation plus
dividends and distributions); (xxi) operating management goals; (xxii) and
execution of pre-approved corporate strategy. The foregoing criteria may relate
to the Company, one or more of its Subsidiaries or one or more of its divisions
or units, or any combination of the foregoing, and may be applied on an absolute
basis and/or be relative to one or more peer group companies or indices, or any
combination thereof, all as the Committee shall determine. In addition, to the
degree consistent with Section 162(m) of the Code (or any successor section
thereto), the performance goals may be calculated without regard to
extraordinary items. In the case of a Performance-Based Award which is not
valued in a way in which the limitation set forth in the final sentence of
Section 3 would operate as an effective limitation satisfying Treasury
Regulation 1.162-27(e)(4), the maximum amount of a Performance-Based Award to
any Participant with respect to performance in a single fiscal year of the
Company shall be $5,000,000. The Committee shall determine whether, with respect
to a performance period, the applicable performance goals have been met with
respect to a given Participant and, if they have, to so certify and ascertain
the amount of the applicable Performance-Based Award. No Performance-Based
Awards will be paid for such performance period until such certification is made
by the Committee. The amount of the Performance-Based Award actually paid to a
given Participant may be less than the amount determined by the applicable
performance goal formula, at the discretion of the Committee. The amount of the
Performance-Based Award determined by the Committee for a performance period
shall be paid to the Participant at such time as determined by the Committee in
its sole discretion after the end of such performance period; provided, however,
that a Participant may, if and to the extent permitted by the Committee and
consistent with the provisions of Section 162(m) of the Code, elect to defer
payment of a Performance-Based Award.

10.  ADJUSTMENTS UPON CERTAIN EVENTS

     Notwithstanding any other provisions in the Plan to the contrary, the
following provisions shall apply to all Awards granted under the Plan:

     (a) Generally. In the event of any change in the outstanding Shares after
the Effective Date by reason of any Share dividend or split, reorganization,
recapitalization, merger, consolidation, spin-off, combination or exchange of
Shares of other corporate exchange, or any large, special, and non-recurring
distribution to Stockholders, the Committee in its sole discretion and without
liability to any person may make such substitution or adjustment, if any, as it
deems to be equitable, as to (i) the number or kind of Shares or other
securities issued or reserved for issuance pursuant to the Plan or pursuant to
outstanding Awards, (ii) the Option Price, (iii) the number and kind of Shares
by which annual per-person Award limitations are measured under Section 3 hereof
and/or (iv) any other affected terms of such Awards (including making provision
for the payment of cash, other Awards or other property in respect of any
outstanding Award). In addition, the Committee is authorized to make adjustments
in the terms and conditions of, and the criteria included in, Awards in
recognition of unusual or nonrecurring events (including, without limitation,
events described in the

                                       10






preceding sentence, as well as acquisitions and dispositions of businesses and
assets) affecting the Company, any subsidiary or any business unit, or the
financial statements of the Company or any subsidiary, or in response to changes
in applicable laws, regulations, accounting principles, tax rates and
regulations or business conditions or in view of the Committee's assessment of
the business strategy of the Company, any subsidiary or business unit thereof,
performance of comparable organizations, economic and business conditions,
personal performance of a Participant, and any other circumstances deemed
relevant; provided that no such adjustment shall be authorized to be made if and
to the extent that such authority or the making of such adjustment would cause
Options, Stock Appreciation Rights, or Performance Awards granted under Section
9(b) hereof intended to qualify as "performance-based compensation" under Code
Section 162(m) and regulations thereunder to otherwise fail to so qualify.

     (b) Change in Control. Except as otherwise provided in an Award agreement,
in the event of a Change in Control, the Committee in its sole discretion and
without liability to any person may take such actions, if any, as it deems
necessary or desirable with respect to any Award (including, without limitation,
(i) the acceleration of an Award, (ii) the payment of a cash amount in exchange
for the cancellation of an Award and/or (iii) the requiring of the issuance of
substitute Awards that will substantially preserve the value, rights and
benefits of any affected Awards previously granted hereunder) as of the date of
the consummation of the Change in Control.

11.  NO RIGHT TO EMPLOYMENT

     The granting of an Award under the Plan shall impose no obligation on the
Company or any Subsidiary to continue the employment of a Participant and shall
not lessen or affect the Company's or Subsidiary's right to terminate the
employment of such Participant.

12.  SUCCESSORS AND ASSIGNS

     The Plan shall be binding on all successors and assigns of the Company and
a Participant, including without limitation, the estate of such Participant and
the executor, administrator or trustee of such estate, or any receiver or
trustee in bankruptcy or representative of the Participant's creditors.

13.  NONTRANSFERABILITY OF AWARDS

     An Award shall not be transferable or assignable by the Participant
otherwise than by will or by the laws of descent and distribution. During the
lifetime of a Participant, an Award shall be exercisable only by such
Participant. An Award exercisable after the death of a Participant may be
exercised by the legatees, personal representatives or distributees of the
Participant. Notwithstanding anything to the contrary herein, the Committee, in
its sole discretion, shall have the authority to waive this Section 13 (or any
part thereof) to the extent that this Section 13 (or any part thereof) is not
required under the rules promulgated under any law, rule or regulation
applicable to the Company.

14.  AMENDMENTS OR TERMINATION

     (a) Changes to the Plan. The Board may amend, alter or discontinue the
Plan, except that (i) any amendment or alteration shall be subject to the
approval of

                                       11




the Company's stockholders at or before the next annual meeting of stockholders
for which the record date is after the date of such Board action if (x) such
stockholder approval is required by any federal or state law or regulation or
the rules of any stock exchange or automated quotation system on which the
Shares may then be listed or quoted, and the Board may otherwise, in its
discretion, determine to submit amendments or alterations to stockholders for
approval or (y) such amendment or alteration would materially increase the
number of shares reserved for the purposes of the Plan, materially broaden the
employees or class of employees eligible to receive Awards under the Plan or
materially increase benefits accruing to employees participating in the Plan;
(ii) without the consent of a Participant, no amendment or alteration shall
materially impair any of the Participant's rights under an Award theretofore
granted to such Participant; and (iii) the Committee may amend or alter the Plan
in such manner as it deems necessary to permit the granting of Awards meeting
requirements of the Code or other applicable laws. Notwithstanding anything to
the contrary herein, the Board may not amend, alter or discontinue the
provisions relating to Section 10(b) of the Plan after the occurrence of a
Change in Control.

     (b) Changes to Outstanding Awards. The Committee may waive any conditions
or rights under, or amend, alter, suspend, discontinue, or terminate any Award
theretofore granted and any Award agreement relating thereto, except as
otherwise provided in the Plan and except that the Committee may not amend or
alter an Award theretofore granted if such action would result in an Award
having terms that would not have been authorized or permitted for a new grant or
Award under the Plan; provided that, without the consent of an affected
Participant, no such Committee action may materially and adversely affect the
rights of such Participant under such Award. Other provisions of the Plan
notwithstanding, if any right under this Plan would cause a transaction to be
ineligible for pooling of interest accounting that would, but for the right
hereunder, be eligible for such accounting treatment, the Committee may modify
or adjust the right so that pooling of interest accounting shall be available,
including the substitution of Shares having a Fair Market Value equal to the
cash otherwise payable hereunder for the right which caused the transaction to
be ineligible for pooling of interest accounting.

15.  INTERNATIONAL PARTICIPANTS

     With respect to Participants who reside or work outside the United States
of America and either who are not (and who are not expected to be) "covered
employees" within the meaning of Section 162(m) of the Code or who are granted
Awards not intended to qualify as "performance-based compensation" under Section
162(m), the Committee may, in its sole discretion, amend the terms of the Plan
or Awards with respect to such Participants in order to conform such terms with
local laws, regulations, or customs or otherwise to meet the objectives of the
Plan, and may, where appropriate, establish one or more sub-plans to reflect
such amended provisions.

16.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of the Plan by the Board nor any submission of the
Plan, specific Plan terms, or amendments thereto to a vote of stockholders of
the Company shall be construed as creating any limitations on the power of the
Board to adopt such other compensatory arrangements as it may deem desirable,
including, without limitation, the granting of awards otherwise than under the
Plan, and such other arrangements may be either applicable generally or only in
specific cases.

                                       12





17.  CHOICE OF LAW

     The Plan shall be governed by and construed in accordance with the laws of
the State of New York.

18.  EFFECTIVENESS OF THE PLAN

     The Plan shall be effective as of the Spinoff Date.


                                       13
