            outstanding options shall be treated as stock owned by the employee.

7.    PARTICIPATION IN THE PLAN

      The Committee shall set forth procedures pursuant to which Participants my
      elect to participate in a given Offering Period under the Plan. Once a
      Participant elects to participate in an Offering Period, such employee
      shall automatically participate in all subsequent Offering Periods, unless
      the employee (a) makes a new election or (b) withdraws from an Offering
      Period or from the Plan pursuant to Section 11 of the Plan.

8.    GRANT OF OPTION ON ENROLLMENT

      Each Participant who elects to participate in a given Offering Period
      shall be granted (as of the Offering Date) an Option to purchase (as of
      the Purchase Date) a number of Shares equal to the lesser of (i) the
      Maximum Share Amount or (ii) the number determined by dividing the amount
      accumulated in such employee's payroll deduction account during such
      Offering Period by the Purchase Price.

9.    PURCHASE PRICE

      The Purchase Price at which a Share will be sold for a given Offering
      Period, as of the Purchase Date, shall be eighty-five percent (85%) of the
      lesser of:

10.   PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF
      SHARES

      Subject to Sections 11 and 12 of the Plan:

            percent (1%) increments, from one percent (1%) to twenty percent
            (20%) of such Participant's Compensation, as elected by the

            permitted to purchase Shares under

                                       6
<Page>

            this Plan (or under any other "employee stock purchase plan" within
            the meaning of Section 423(b) of the Code, of the Company or any of
            its Subsidiaries) with an aggregate Fair Market Value (as determined
            as of each Offering Date) in excess of $21,250 for any one calendar
            year within the meaning of Section 423(b)(8) of the Code. For a
            given Offering Period, payroll deductions shall commence on the
            Offering Date and shall end on the related Purchase Date, unless
            sooner altered or terminated as provided in the Plan.

      (b)   A Participant shall not change the rate of payroll deductions once
            an Offering Period has commenced. The Committee shall specify
            procedures by which a Participant may increase or decrease the rate
            of payroll deductions for subsequent Offering Periods.

      (c)   All payroll deductions made with respect to a Participant shall be
            credited to his or her Payroll Deduction Account under the Plan and
            shall be deposited with the general funds of the Company, and no
            interest shall accrue on the amounts credited to such Payroll
            Deduction Accounts. All payroll deductions received or held by the
            Company may be used by the Company for any corporate purpose, and
            the Company shall not be obligated to segregate such payroll
            deductions. A Participant may not make any separate cash payment
            into his or her Payroll Deduction Account, and payment for Shares
            purchased under the Plan may not be made in any form other than by
            payroll deduction.

      (d)   On each Purchase Date, the Company shall apply all funds then in the
            Participant's Payroll Deduction Account to purchase Shares (in whole
            and/or fractional Shares, as the case may be) pursuant to the Option
            granted on the Offering Date. In the event that the number of Shares
            to be purchased by all Participants in one Offering Period exceeds
            the number or Shares then available for issuance under the Plan, (i)
            the Company shall make a pro rata allocation of the remaining Shares
            in as uniform a manner as shall be practicable and as the Committee
            shall determine to be equitable and (ii) all funds not used to
            purchase Shares on the Purchase Date shall be returned, without
            interest, to the Participant.

      (e)   As soon as practicable following the end of each Offering Period,
            the number of Shares purchased by each Participant shall be
            deposited into an account established in the Participant's name with
            the Plan Broker. Unless otherwise permitted by the Committee in its
            sole discretion, dividends that are declared on the Shares held in
            such account shall be reinvested in whole or fractional Shares.

      (f)   Once the holding period set forth in Section 423(a) of the Code has
            been satisfied with respect to a Participant's Shares, the
            Participant may (i)

                                       7
<Page>

            keep his or her shares in the account established in the
            Participant's name with the Plan Broker, (ii) transfer his or her
            Shares to another brokerage account of Participant's choosing or
            (iii) request in writing that a stock certificate be issued to him
            or her with respect to the whole Shares in his or her Plan Broker
            account and that any fractional Shares remaining in such account be
            paid in cash to him or her. The Committee may require, in its sole
            discretion, that the Participant bear the cost of transferring such
            Shares or issuing certificates for such Shares. Any Participant who
            engages in a "Disqualifying Disposition" of his or her Shares within
            the meaning of Section 421(b) of the Code shall notify the Company
            of such Disqualifying Disposition in accordance with Section 20 of
            the Plan.

      (g)   The Participant shall have no interest or voting right in the Shares
            covered by his or her Option until such Option is exercised.

11.   WITHDRAWAL

      Each Participant may withdraw from an Offering Period or from the Plan
      under such terms and conditions as are established by the Committee in its
      sole discretion. Upon a Participant's withdrawal from an Offering Period
      or from the Plan, all accumulated payroll deductions in the Payroll
      Deduction Account shall be returned, without interest, to such
      Participant, and he or she shall not be entitled to any Shares on the
      Purchase Date or thereafter with respect to the Offering Period in effect
      at the time of such withdrawal. Such Participant shall be permitted to
      participate in subsequent Offering periods pursuant to such terms and
      conditions established by the Committee in its sole discretion.

12.   TERMINATION OF EMPLOYMENT

      A Participant shall cease to participate in the Plan upon his or her
      termination of employment for any reason (including, but not limited to,
      Retirement, death or Disability). In such event, all payroll deductions
      credited to the Participant's Payroll Deduction Account shall be returned,
      without interest, to such Participant or to his or her designated
      beneficiary, as the case may be, and such Participant or beneficiary shall
      have no future rights in any unexercised Options under the Plan.

13.   ADJUSTMENTS UPON CERTAIN EVENTS

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

                                       8

            exchange of Shares or other corporate exchange, or any distribution
            to stockholders of Shares other than regular cash dividends, 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,
            (ii) the Purchase Price and/or (iii) any other affected terms of
            such Options.

            may take such actions, if any, as it deems necessary or desirable
            with respect to any Option as of the date of the consummation of the
            Change in Control.

14.   NONTRANSFERABILITY

      No Options granted under the Plan shall be transferable or assignable by
      the Participant otherwise than by will or by the laws of descent and
      distribution.

15.   NO RIGHT TO EMPLOYMENT

      The granting of an Option 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.

16.   SECTION 423 OF THE CODE

      The Plan is intended to qualify as an "employee stock purchase plan"
      within the meaning of Section 423 of the Code or any successor section
      thereto. Accordingly, all Participants shall have the same rights and
      privileges under the Plan, subject to any exceptions that are permitted
      under Section 423(b)(5) of the Code. Any provision of the Plan that is
      inconsistent with Section 423 of the Code or any successor provision
      shall, without further act or amendment, be reformed to comply with the
      requirements of Section 423. This Section 16 shall take precedence over
      all other provisions in the Plan.

17.   AMENDMENT OR TERMINATION OF THE PLAN

      The Plan shall continue until the earliest to occur of the following: (a)
      termination of the Plan by the Board, (b) issuance of all of the Shares
      reserved for issuance under the Plan, (c) June 30, 2008 or (d) failure to
      satisfy the conditions of Section 22 of the Plan. The Board may amend,
      alter or discontinue the Plan, but no amendment, alteration or
      discontinuation shall be made which, (a) without the approval of the
      stockholders of the Company, would (except as is provided in Section 13 of
      the Plan), increase the total number of Shares reserved for the purposes
      of the Plan or (b) without the consent of a Participant, would impair any
      of the rights or obligations under any Option theretofore granted to such
      Participant under the Plan; PROVIDED, HOWEVER, that the Committee may
      amend the Plan in such manner as it deems necessary to permit the granting
      of Options meeting the requirements of the Code or other applicable laws.

18.   TAX WITHHOLDING

      The Participant's employer shall have the right to withhold from such
      Participant such withholding taxes as may be required by federal, state,
      local or other law, or to otherwise require the Participant to pay such
      withholding taxes.

19.   INTERNATIONAL PARTICIPANTS

      With respect to Participants who reside or work outside the United States
      of America, 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 to the requirements of local law.

21.   CHOICE OF 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
      the State of New York.

22.   EFFECTIVENESS OF THE PLAN

      The Plan shall become effective on the date on which it is adopted by the
      Board (the "Effective Date"); provided, however, that the Plan must be
      approved within twelve (12) months after the Effective Date by the
      stockholders of the Company. The Company may commence payroll deductions
      on behalf of Participants pursuant to the Plan prior to such stockholder
      approval; provided, however, that the use of such payroll deductions to
      purchase Shares pursuant to the exercise of Options hereunder is
      contingent upon stockholder approval of the Plan. If stockholder approval
      of the Plan is not obtained prior to the first Purchase Date, the Plan
      shall terminate and all amounts withheld through payroll deduction or held
      in a Participant's Payroll Deduction Account shall be returned to such
      Participant, without interest.

<Page>

12.   CONTENTS OF STOCK OPTION AGREEMENT

      A Stock Option Agreement issued in respect of an Option shall be issued to
      the Participant as soon as practicable after the Date of Grant and shall
      state:

            that it is issued in respect of an Option;

            the Date of Grant of the Option;

            the number of Shares subject to the Option;

            the Option Price under the Option;

            the Expiration Date of an Option;

            any performance target or other condition imposed on the exercise
            of the Option;

            the date(s) on which the Option will ordinarily become exercisable;
            and

            the date(s) on which the Option will become exercisable in the event
            of a Change in Control under Section 9(b)(i) of the Plan.

13.   EARLIEST DATE FOR GRANT OF OPTIONS

      An Option may not be granted earlier than the Approval Date.

14.   PERSONS TO WHOM OPTIONS MAY BE GRANTED

      An Option may not be granted to an individual who is not an Eligible
      Employee at the Date of Grant.

15.   OPTIONS NON TRANSFERABLE

      Notwithstanding Section 12 of the Plan, an Option shall be personal to the
      Eligible Employee to whom it is granted and, subject to rule 25, shall not
      be capable of being transferred, charged or otherwise alienated and shall
      lapse immediately if the Participant purports to transfer, charge or
      otherwise alienate the Option.

16.   LIMIT ON NUMBER OF SHARES PLACED UNDER OPTION UNDER SUB-PLAN

      For the avoidance of doubt, Shares placed under Option under the Sub-Plan
      shall be taken into account for the purpose of Section 3 of the Plan.

17.   INLAND REVENUE LIMIT ((POUND)30,000)

      An Option may not be granted to an Eligible Employee if the result of
      granting the Option would be that the aggregate Market Value of the shares
      subject to all outstanding options granted to him under the Sub-Plan or
      any other share option scheme established by the Company or an Associated
      Company and

                                       5
<Page>

      approved by the Inland Revenue under Schedule 9 to ICTA 1988 (other than a
      savings related share option scheme) would exceed sterling (pound)30,000
      or such other limit as may from time to time be specified in paragraph 28
      of Schedule 9 to ICTA 1988.(10) For this purpose, the United Kingdom
      sterling equivalent of the Market Value of a share on any day shall be
      determined by taking the spot sterling/US dollar exchange rate for that
      day as shown in the Financial Times. If the grant of an Option would
      otherwise cause the limit in this rule 17 to be exceeded, it shall take
      effect as the grant of an Option under the Sub-Plan over the highest
      number of Shares which does not cause the limit to be exceeded.

18.   OPTION PRICE UNDER OPTIONS

      Notwithstanding Section 6(a) of the Plan, the amount payable per Share on
      the exercise of an Option shall not be less than the Market Value of a
      Share on the Date of Grant and shall be stated on the Date of Grant.

19.   PERFORMANCE TARGET OR OTHER CONDITION IMPOSED ON EXERCISE OF AN OPTION

      Any performance target or other condition imposed on the exercise of an
      Option under Section 6(b) of the Plan shall be:

      19.1  objective;

      19.2  such that, once satisfied, the exercise of the Option is not
            subject to the discretion of any person; and

      19.3  stated on the Date of Grant.

      If an event occurs as a result of which the Plan Administrator considers
      that a performance target or other condition imposed on the exercise of an
      Option is no longer appropriate and substitutes, varies or waives under
      Sections 9(a) or 13(b) of the Plan the performance target or condition,
      such substitution, variation or waiver shall:

      19.4  be reasonable in the circumstances; and

      19.5  produce a fairer measure of performance and be neither materially
            more nor less difficult to satisfy.

20.   EXERCISE OF OPTIONS BY LEAVERS

20.1  Notwithstanding Section 6(e) of the Plan, if a Participant ceases to be
      employed by the Company and its Subsidiaries before the Expiration Date of
      his Option by reason of Disability, he shall be entitled to exercise his
      Options in full at any time during the period ending on the earlier of:

      20.1.1 five years after the date of Disability or

      20.1.2 the Expiration Date of the Option

      and thereafter his Options, to the extent unexercised, shall lapse.

                                       6

20.2  Notwithstanding Section 6(f) of the Plan, if a Participant ceases to be
      employed by the Company and its Subsidiaries before the Expiration Date of
      the Option by reason of Retirement, he shall be entitled to exercise his
      Options to the extent exercisable (unvested Options will be forfeited) at
      the time of such Retirement at any time during the period ending on the
      earlier of:

      20.2.2 the Expiration Date of the Option, or
      20.2.3 the later of:

         20.2.3.1  five years after the date of Retirement; and
         20.2.3.2  12 months from the date of his death

      and thereafter his Options, to the extent unexercised, shall lapse.

20.3  Notwithstanding Section 6(g) of the Plan, if a Participant ceases to be
      employed by the Company and its Subsidiaries for any reason other than
      those referred to in rules 20.1, 20.2 and 25, or by reason of his injury
      or redundancy the Committee may, at its discretion, allow him to exercise
      his Options to the extent exercisable at the time his employment ceases at
      any time during the period ending 90 days after the date of cessation of
      his employment. If not exercised, his Options shall immediately lapse.

21.   LATEST DATE FOR EXERCISE OF OPTIONS

      Subject to rule 25, an Option may not be exercised more than ten years
      after the Date of Grant and to the extent not so exercised by that time
      the Option shall lapse immediately.

22.   MATERIAL INTEREST

      An Option may not be exercised if the Participant then has, or has had
      within the preceding twelve months, a Material Interest in a Close Company
      which is the Company or which is a company which has Control of the
      Company or which is a member of a Consortium which owns the Company.

23.   MANNER OF PAYMENT FOR SHARES ON EXERCISE OF OPTIONS

      The amount due on the exercise of an Option shall be paid in cash or by
      cheque or banker's draft and may be paid out of funds provided to the
      Participant on loan by a bank, broker or other person. Notwithstanding
      Sections 6(c)(ii) and 6(c)(iii) of the Plan, the amount may not be paid by
      the transfer to the Company of Shares or any other shares or securities.
      The date of exercise of an Option shall be the date on which the Company
      receives the amount due on the exercise of the Option.

                                       7
<Page>

24.   ISSUE OR TRANSFER OF SHARES ON EXERCISE OF OPTIONS

24.1  Notwithstanding Sections 6(c) and 17 of the Plan and subject only to
      compliance by the Participant with the rules of the Sub-Plan and to any
      delay necessary to complete or obtain:

      24.1.1   the listing of the Shares on any stock exchange on which Shares
               are then listed; and

      24.1.2   such registration or other qualification of the Shares under any
               applicable law, rule or regulation as the Company determines is
               necessary or desirable

      the Company shall, as soon as reasonably practicable and in any event not
      later than thirty days after the date of exercise of an Option, issue or
      transfer to the Participant, or procure the issue or transfer to the
      Participant of, the number of Shares specified in the notice of exercise
      and shall deliver to the Participant, or procure the delivery to the
      Participant of, a Share Certificate in respect of such Shares or shall
      procure the electronic transfer of such shares to an account of the
      Participant.

24.2  The exercise shall be considered only conditional, until the Participant
      has made provision for the payment or withholding of any taxes required to
      be withheld in accordance with the applicable law of any foreign
      jurisdiction in respect of the exercise of the Option or the receipt of
      the Shares.

25.   DEATH OF PARTICIPANT

      Notwithstanding Section 6(e) of the Plan and rule 20, if a Participant
      dies before the Expiration Date of the Option, his personal
      representatives shall be entitled to exercise his Options in full at any
      time during the twelve month period following his death even if the Option
      would have otherwise expired. If not so exercised, the Options shall lapse
      immediately.

26.   CHANGE IN CONTROL OF COMPANY

26.1  EXCHANGE OF OPTIONS

      If a company ("Acquiring Company") obtains Control of the Company as a
      result of making:

      26.1.1   a general offer to acquire the whole of the issued ordinary share
               capital of the Company which is made on a condition such that if
               it is satisfied the person making the offer will have Control of
               the Company; or

      26.1.2   a general offer to acquire all the shares in the Company of the
               same class as the Shares

      a Participant may, at any time during the period set out in rule 26.2, by
      agreement with the Acquiring Company, release his Option in whole or in
      part

                                       8
<Page>

      in consideration of the grant to him of a new option ("New Option") which
      is equivalent to the Option but which relates to shares ("New Shares") in:

      26.1.3   the Acquiring Company;

      26.1.4   a company which has Control of the Acquiring Company; or

      26.1.5   a company which either is, or has Control of, a company which is
               a member of a Consortium which owns either the Acquiring Company
               or a company having Control of the Acquiring Company.

26.2  PERIOD ALLOWED FOR EXCHANGE OF OPTIONS

      The period referred to in rule 26.1 is the period of six months beginning
      with the time when the person making the offer has obtained Control of the
      Company and any condition subject to which the offer is made has been
      satisfied.

26.3  MEANING OF "EQUIVALENT"

      The New Option shall not be regarded for the purpose of this rule 26 as
      equivalent to the Option unless:

      26.3.1   the New Shares satisfy the conditions in paragraphs 10 to 14 of
               Schedule 9 to ICTA 1988; and

      26.3.2   save for any performance target or other condition imposed on the
               exercise of the Option, the New Option will be exercisable in the
               same manner as the Option and subject to the provisions of the
               Sub-Plan as it had effect immediately before the release of the
               Option; and

      26.3.3   the total market value, immediately before the release of the
               Option, of the Shares which were subject to the Option is equal
               to the total market value, immediately after the grant of the New
               Option, of the New Shares (market value being determined for this
               purpose in accordance with Part VIII of the Taxation of
               Chargeable Gains Act 1992); and

       26.3.4  the total amount payable by the Participant for the acquisition
               of the New Shares under the New Option is equal to the total
               amount that would have been payable by the Participant for the
               acquisition of the Shares under the Option.

26.4  DATE OF GRANT OF NEW OPTION

      The date of grant of the New Option shall be deemed to be the same as the
      Date of Grant of the Option.

                                       9
<Page>

26.5  APPLICATION OF SUB-PLAN TO NEW OPTION

      In the application of the Sub-Plan to the New Option, where appropriate,
      references to "Company" and "Shares" shall be read as if they were
      references to the company to whose shares the New Option relates and the
      New Shares, respectively, save that in the definition of "Committee" the
      reference to "Board" shall be read as if it were a reference to the Board
      of IMS Health Incorporated.

26.6  DISAPPLICATION OF SECTION 9 OF THE PLAN

      References in Section 9(b)(iii) of the Plan to substitution of Options
      with comparable awards, shall be disapplied for the purposes of the
      Sub-Plan to the extent that such substitution does not satisfy the
      requirements of Paragraph 15 of Schedule 9 to ICTA 1988.

      If an exchange of Options in accordance with this rule 26 is not possible,
      and a substitution under Section 9(b) of the Plan does not satisfy the
      requirements of paragraph 15 of Schedule 9 to ICTA 1988, the Option shall
      lapse on the termination of the corporate existence of the Company in
      connection with the Control transaction.

27.   RIGHTS ATTACHING TO SHARES ISSUED ON EXERCISE OF OPTIONS

      Notwithstanding Section 6(d) of the Plan, all Shares issued on the
      exercise of an Option shall, as to any voting, dividend, transfer and
      other rights, including those arising on a liquidation of the Company,
      rank equally in all respects and as one class with the shares of the same
      class in issue at the date of such exercise save as regards any rights
      attaching to such shares by reference to a record date prior to the date
      of such exercise.

28.   AMENDMENT OF SUB-PLAN

      Notwithstanding Sections 4(a) and 13(a) of the Plan, no amendment of the
      Sub-Plan, whether taking the form of an amendment of the Plan or this
      schedule, shall take effect until it has been approved by the Inland
      Revenue.

29.   ADJUSTMENT OF OPTIONS

      Notwithstanding Sections 4(c), 9(a) and 13(b) of the Plan, any adjustment
      of an Option:

      29.1 shall not be made unless the adjustment is permitted pursuant to
      paragraph 29(7) of Schedule 9 to ICTA 1988; and

      29.2 shall not take effect until it has been approved by the Inland
      Revenue.

30.   EXERCISE OF DISCRETION BY COMMITTEE

      In exercising any discretion which it may have under the Sub-Plan, the
      Committee shall act fairly and reasonably.

                                       10
<Page>

31.   DISAPPLICATION OF CERTAIN PROVISIONS OF PLAN

      The provisions of the Plan dealing with:

            Stock Appreciation Rights;

            LSARs; and/or

            Other Stock-Based Awards

      shall not form part of, and no such rights may be granted under, the
      Sub-Plan.

      The following sections of the Plan shall be disapplied for the purposes of
      the Sub-Plan:

            the words "with the exception of certain non-US  jurisdictions"  in
            Section 6(b);

            the sentence in Section 6(c) "Unless otherwise provided by the
            Committee, the participant may 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 or other
            taxes as a result of the exercise of the Option.";

            Section 6(d);

            Sections 9(a)(iii) and 9(b)(ii) relating to the payment of cash on
            cancellation of Options; and

            Sections 16(a) and 16(b) relating to the payment of taxes in Shares
            or by the withholding of Shares that would have otherwise been
            received by the Participant.

--------
(1) The Company is the "grantor" as defined in paragraph 1 of Schedule 9 to ICTA
1988 because it has established the Sub-Plan. In most cases, it will also be the
Company which grants options under the Sub-Plan, although this is not a
requirement of UK tax legislation.

(2) A company is treated as another's "associated company" at a given time if,
at that time or at any other time within one year previously, one of the two has
control of the other, or both are under the control of the same person or
persons. A person is taken to have control of a company if he exercises, or is
able to exercise or is entitled to acquire, direct or indirect control over the
Company's affairs and, in particular, if he possesses or is entitled to acquire
the greater part of the Company's issued share capital or the voting power in
the company. UK tax legislation contains two definitions of control: the
definition of control here is different from that in paragraph 5 below.

(3) A close company is a company which is under the control (as defined in
paragraph 5 below) of five or fewer participators (eg shareholders) or of any
number of participators who are directors. There are attributed to a
participator all the rights and powers (eg shares, voting power) of, inter alia,
a company which he controls or of an "associate" (eg relative) of his.
Ordinarily, a company is excluded from being a close company if it is non UK
resident or 35% of the voting power in the company is held by

                                       11
<Page>

--------------------------------------------------------------------------------

the public and its shares have been listed, and the subject of dealings, on a
recognised stock exchange within the preceding 12 months. However, for the
purpose of the material interest test (see paragraph 8 below), this exclusion
does not apply with the result that the normal definition of a "close company"
is extended.

(4) A company is a member of a consortium owning another company if it is one of
a number of companies which between them beneficially own not less than
three-quarters of the other company's ordinary share capital and each of which
beneficially owns not less than one-twentieth of that capital.

(5) Control means the power of a person to secure:

(a)   by means of the holding of shares or the possession of voting power in or
      in relation to that or any other body corporate; or

(b)   by virtue of any powers conferred by the articles of association or other
      document regulating that or any other body corporate

that the affairs of the first-mentioned body corporate are conducted in
accordance with the wishes of that person.

(6) The expression "recognised stock exchange" is defined in section 841 of ICTA
1988. "Recognised stock exchange" means the London Stock Exchange Limited and
any stock exchange outside the UK which has been designated by the Inland
Revenue as a recognised stock exchange. This includes, inter alia, the New York
Stock Exchange, NASDAQ and any exchange registered with the US Securities and
Exchange Commission as a national securities exchange. However, clearance is
required from the Shares Valuation Division before the NASDAQ price may be used
to determine the market price of a NASDAQ listed share.

(7) Market value in this context means the price which the shares used in the
scheme might reasonably be expected to fetch on a sale in the open market
(section 272 Taxation of Chargeable Gains Act 1992 ("TCGA 1992"). In making this
determination, it is assumed that there is available to any prospective
purchaser of the shares all the information which a prudent prospective
purchaser of the shares might reasonably require if he were proposing to
purchase the shares from a willing vendor by private treaty and at arm's length.

(8) A person has a material interest in a company if he, either on his own or
with one or more associates, or if any associate of his with or without such
other associates:

(a)   is the beneficial owner of, or able, directly or through the medium of
      other companies, or by any other indirect means to control, more than 10
      per cent of the ordinary share capital of the company; or

(b)   where the company is a close company, possesses, or is entitled to
      acquire, such rights as would, in the event of the winding-up of the
      company or in any other circumstances, give an entitlement to receive more
      than 10 per cent of the assets which would then be available for
      distribution among the participators.

(9) The shares used in the scheme must be:

(a)   ordinary shares;

(b)   fully paid up;

(c)   not redeemable; and

(d) save for certain limited exceptions, not subject to any restrictions which
    do not apply to all shares of the same class.

                                       12
<Page>

--------------------------------------------------------------------------------

The shares used in the scheme must be:

(a)   of a class listed on a recognised stock exchange; or

(b)   shares in a company which is not under the control of another company; or

(c)   shares in a company which is under the control of another company (other
      than a company which is, or would if resident in the UK be, a close
      company) whose shares are listed on a recognised stock exchange.

The shares used in the scheme form part of the ordinary share capital of:

(a)   the grantor (ie the company which has established the scheme); or

(b)   a company which has control of the grantor; or

(c)   a company which either is, or has control of, a company which is a member
      of a consortium owning either the grantor or a company having control of
      the grantor.

Where the company whose shares are to be used in a scheme has more than one
class of ordinary share, the majority of the issued shares of the same class as
those which are to be used must be either employee control shares (see below)
or:

(a)   must not be held by persons (including trustees holding shares on behalf
      of such persons) who acquired their shares in pursuance of a right
      conferred on them or opportunity offered to them as directors or employees
      of any company, and not in pursuance of an offer to the public; and

(b)   if the shares are not listed on a recognised stock exchange and the
      company is under the control of another company whose shares are so
      listed, must not be held by companies which have control of the company
      whose shares are in question or of which that company is an associated
      company.

Shares are employee control shares if:

(a)   the persons holding them are, by virtue of their holding of shares of that
      class, together able to control the company; and

(b)   those persons are, or have been, employees or directors of the company or
      of another company which is under the control of the company.

(10) UK tax legislation imposes a limit (currently (pound)30,000) on the "value"
of the outstanding options which may be held by an individual participant in an
Inland Revenue approved executive share option scheme. The (pound)30,000 limit
is calculated by reference to the market value of the shares at the date of
grant of the relevant option and is not recalculated for any changes in the
share value during the life of the option. When an option is exercised, the
shares in respect of which the option is exercised drop out of the account for
the purpose of the (pound)30,000 limit, this creating scope for the grant of an
option over further shares to the same individual.
