3.  Participation

  Participation in the Plan is voluntary.  All Eligible Employees of an Employer
are eligible to participate in the Plan.  All Eligible Employees granted rights
to purchase Shares hereunder shall have the same rights and privileges as every
other such Eligible Employee and only Eligible Employees of an Employer
satisfying the applicable participation requirements of the Plan will be
entitled to participate in the Plan.

4.   Enrollment and Election Periods

   (a) Enrolling in the Plan.  To participate in the Plan, an Eligible Employee
       ---------------------
must enroll in the Plan.  Enrollment for a given Election Period will take place
during the Enrollment Period for such Election Period.  The Committee shall
designate the initial Enrollment Period and each subsequent Enrollment Periods
and the Election Periods to which each Enrollment Period relates.  Participation
in the Plan with respect to any one or more of the Election Periods shall
neither limit nor require participation in the Plan for any other Election
Period.

   (b) The Election Period.  Any Employee who is an Eligible Employee and who
       -------------------
desires to be granted rights to purchase Shares hereunder must enroll, in
accordance with the procedures established by the Committee, during an
Enrollment Period.  Such authorization shall be effective for the Election
Period immediately following such Enrollment Period.

       The duration of an Election Period shall be determined by the Committee
prior to the Enrollment Period; provided however that, if the Committee
terminates the Plan during an Election Period, pursuant to its authority in
Paragraph 17 of the Plan, such Election Period shall be deemed to end on the
date the Plan is terminated.  The termination of the Plan and the Election
Period shall end the Participant's rights to contribute amounts to the Plan or
continue participation in the Election Period.  The date of termination of the
Plan shall be deemed to be the final day of the Election Period for purposes of
determining the Purchase Price under the Election Period and all amounts
contributed during the Election Period will be used as of such termination date
to purchase Shares in accordance with the provisions of Paragraph 9 of this Plan
or alternatively, at the sole discretion of the Committee, refunded in cash
without interest or where required under the applicable Local Law with interest.

       The Committee may designate one or more Election Periods during each Plan
Year during the term of this Plan.  On the first day or the first Trading Day of
each Election Period, as determined by the Committee, each Participant shall be
granted a right to purchase Shares under the Plan.  Each right granted hereunder
shall expire at the end of the Election Period for which it was granted.  In no
event may a right granted hereunder be exercised later than the period of time
specified in section 423(b)(7)(B) of the Code.  Except as otherwise provided in
Paragraph 9, a right to purchase Shares granted under the Plan shall be treated
as exercised on the last Trading Day of each Election Period.

   (c) Changing Enrollment. The offering of Shares pursuant to rights granted
       -------------------
under the Plan shall occur only during an Election Period and shall be made only
to Participants.  Once an Eligible Employee is enrolled in the Plan, the
Committee or the Employer will inform the Administrator of such fact.

       Once enrolled, a Participant shall continue to participate in the Plan
for each successive Election Period(s) until he or she terminates his or her
participation by revoking his or her payroll

                                       5
<PAGE>

deduction authorization or by revoking his or her alternative contribution
authorization or not contributing his or her alternative contributions or ceases
to be an Eligible Employee.

       Once a Participant has elected to participate under the Plan, that
Participant's payroll deduction authorization or alternative contribution
authorization shall apply to all subsequent Election Periods unless and until
the Participant ceases to be an Eligible Employee or the Participant changes or
terminates said authorization.

       Unless otherwise required by the applicable Local Law if a Participant
desires to change his or her rate of contribution during an Election Period such
change shall be effective for the next Election Period and only if such change
is made by the Participant giving notice to the Committee or the Employer in the
manner established by the Committee.

5.   Term of Plan

  This Plan shall be in effect from September 1, 2001, and end after August 31,
2011.

6.   Number and Type of Shares to Be Made Available Under The Plan

  Subject to adjustment as provided in Paragraph 16 hereof, the total number of
Shares made available for purchase by Participants granted rights which are
exercised under Paragraph 9 hereof is,   three hundred thousand (300,000)
Shares, which may consist of authorized but unissued shares, treasury shares, or
shares purchased by the Company in the open market.  The provisions of Paragraph
9(d) shall control in the event the number of Shares covered by rights which are
exercised for any Election Period exceeds the number of Shares available for
sale under the Plan.  If all of the Shares authorized for sale under the Plan
have been sold, the Plan shall either be continued through additional
authorizations of Shares made by the Board (such authorizations must, however,
comply with Paragraph 17 hereof), or shall be terminated in accordance with
Paragraph 17 hereof.

7.   Use of Funds

  All payroll deductions or alternative contributions received or held by an
Employer under the Plan will be used to purchase Shares in accordance with the
provisions of this Plan.  Any amounts held by an Employer or other party holding
amounts in connection with or as a result of payroll deductions or alternative
contributions made pursuant to the Plan and pending the purchase of Shares
hereunder shall be considered a non-interest-bearing, unsecured indebtedness
extended to the Employer or other party by the Participants, unless otherwise
required under the applicable Local Law. Administrative expenses of the Plan
shall be allocated to each Participant's Plan Account unless the Employer pays
such expenses.  The Participant agrees to sign any and all appropriate documents
to facilitate such allocation.

8.      Amount of Contribution; Method of Payment

   (a) Payroll Deduction or Alternative Contribution.  Except as otherwise
       ---------------------------------------------
specifically provided herein, the Purchase Price will be payable by each
Participant by means of payroll deduction or alternative contribution.  The
payroll deduction or alternative contribution shall be in increments of one

                                       6
<PAGE>

percent (1%).  Unless otherwise authorized by the Committee, the minimum payroll
deduction or alternative contribution permitted shall be an amount equal to two
percent (2%) of a Participant's Compensation and the maximum payroll deduction
or alternative contribution shall be an amount equal to fifteen percent (15%) of
a Participant's Compensation.  In any event, the total payroll deduction or
alternative contribution permitted to be made by any Participant in any calendar
year shall be limited to the sum of legal currency equivalent of U.S. $25,000 as
specified under Section 423(b)(8)(C), or such other amount as Section
423(b)(8)(C) of the Code, or any successor section, may hereafter allow.  The
actual percentage of Compensation to be deducted or contributed shall be
specified by a Participant in his or her authorization to participate in the
Plan.  Unless otherwise authorized by the Committee, Participant may not deposit
any separate cash payments into his/her Plan Account.

       Payroll deductions will commence with the first payroll issued during the
Election Period and will, except as otherwise provided herein, continue with
each payroll throughout the entire Election Period, except for pay periods for
which such Participant receives no Compensation.   A pay period which ends at
such time that it is administratively impracticable to credit any payroll for
such pay period to the then current Election Period will be credited in its
entirety to the immediately subsequent Election Period.  A pay period that
overlaps Election Periods will be credited in its entirety to the Election
Period in which it is paid.  Alternative contributions will be made in
accordance with the procedure established by the Committee.

   (b) Application of Withholding Rules.  Payroll deductions or alternative
       --------------------------------
contributions shall be retained by the Employer or other party, designated by
the Committee or the Employer as the case may be, until applied to the purchase
of Shares as described in Paragraph 9 hereof and the satisfaction of any related
withholding obligations (including any employment tax obligations) under the
applicable Local Law.

       At the time the Shares are purchased, or at the time some or all of the
Shares issued under the Plan are disposed of, Participants must make adequate
provision for the Employer's tax withholding obligations (including any
employment tax obligations), if any, which arise in any applicable jurisdiction
upon the purchase or disposition of the Shares.  Subject to the applicable Local
Law and the Holding Period, if any, the Employer may instruct the Administrator
to dispose or sell such number of Shares (credited to the Participant's Plan
Account) to raise the amount necessary, or may withhold from each Participant's
Compensation the amount necessary, to enable the Employer to meet applicable
withholding obligations, including any withholding required to make available to
the Employer any tax deductions or benefits attributable to the sale or early
disposition of Shares by the Participant.  Each Participant, as a condition of
participating under the Plan, agrees to bear responsibility for all taxes
required to be withheld in any applicable jurisdiction from his or her
Compensation as well as the Participant's portion of applicable social security
or similar such taxes, with respect to any Compensation arising on account of
the purchase or disposition of Shares.  The Employer may increase income and/or
employment tax withholding on a Participant's Compensation after the purchase or
disposition of Shares in order to comply with the applicable tax laws in any
jurisdiction.  The Participant agrees to sign any and all appropriate documents
to facilitate payment of all applicable taxes by the Employer, including but not
limited to withholding by the Employer from Participant's Compensation, or by
the Employer instructing the Administrator to sell the required number of
Shares.

9.      Purchasing, Transferring Shares

   (a) Maintenance of Plan Account. Upon the exercise of a Participant's initial
       ---------------------------
right to purchase Shares under the Plan, the Administrator shall establish a
Plan Account in the name of such Participant. At the close of each Election
Period, the aggregate amount deducted during such Election Period by the
Employer from a Participant's Compensation by way of payroll deduction or
alternative contributions made to the Plan by the Participant (and credited to
an account maintained by the Employer or other party) and interest, if any,
payable under the applicable Local Law will be communicated by the Employer to
the Administrator. The Company shall convert the said payroll deductions or
alternative contributions into US dollars in accordance with the process and at
the rate established by the Committee. The Administrator shall thereupon credit
to the Participant's Plan Account such US dollars. As of the last day of each
Election Period, or as soon thereafter as is administratively practicable, each
Participant's right to purchase Shares will be exercised automatically for him
or her by the Administrator with respect to those amounts reported to the
Administrator by the Committee or Employer as credited to that Participant's
Plan Account. On the date of exercise, the amount then credited to the
Participant's Plan Account for the purpose of purchasing Shares hereunder will
be divided by the Purchase Price and there shall be credited to the
Participant's Plan Account by the Administrator the number of whole Shares which
results. The Administrator shall hold in its name, or in the name of its
nominee, all Shares so purchased by Participants under the Plan.

   (b)  Share Price and Exchange Fluctuation Risk. Participation in the Plan,
        -----------------------------------------
purchase, ownership and sale of Shares under the Plan, is subject to risk of
fluctuation in Shares' price and currency exchange.

   (c) Insufficient Funds for Whole Shares.  In the event that the amount
       -----------------------------------
credited to Participant's Plan Account is not exactly equal to the Purchase
Price for a whole number of Shares, then any excess amount may be refunded to
the Participant without interest or where required by the applicable Local Law
with interest, or may be used to purchase Shares in the subsequent Election
Periods, as determined by the Committee.

   (d) Insufficient Number of Available Shares.  In the event the number of
       ---------------------------------------
Shares covered by rights which are exercised for any Election Period exceeds the
number of Shares available for sale under the Plan, the number of Shares
actually available for sale hereunder shall be allocated by the Administrator
among the Participants in proportion to the amount then credited to each
Participant's Plan Account over the total amount then credited to all
Participant's Plan Accounts.  Any excess amounts withheld and credited to
Participants' Plan Accounts then shall be returned to the Participants as soon
as is administratively practicable without interest or where required by the
applicable Local Law with interest.

   (e) Handling Excess Shares.  In the event that the number of Shares which
       ----------------------
would be credited to any Participant's Plan Account in any Election Period
exceeds the limit specified in Paragraph 2(l)(iii) hereof, such Participant's
Plan Account shall be credited with the maximum number of Shares permissible,
and the remaining amounts will be refunded in cash as soon as administratively
practicable without interest or where required by the applicable Local Law with
interest or used to purchase Shares in the subsequent Election Periods, as
determined by the Committee.

10.  Dividends and Other Distributions

   (a) Subject to the applicable Local Law, cash dividends and other cash
distributions and stock dividends and other non-cash distributions received by
the Administrator on Shares held in  custody hereunder will be credited to the
Plan Account of an individual Participant in accordance with such Participant's
interest in the Shares with respect to which such dividends or distributions are
paid.

   (b) Cash dividends or cash distributions will be paid in cash to the
Participant as soon as administratively possible, after receipt thereof by the
Administrator.

   (c)  Stock dividends and other non-cash distributions of property will be
subject to the similar Holding Period, if any applicable to the Shares with
respect to which the same is declared.

   (d) Tax Responsibilities.  The Administrator shall report to each Participant
       --------------------
(or Eligible Employee with a Plan Account) the amount of dividends credited to
his or her Plan Account.  Subjecting the stock dividends or other non-cash
distributions to the Holding Period requirement will not relieve a Participant
(or Eligible Employee with Plan Account) of any income or other tax that may be
due on or with respect to such dividend or other non-cash distribution of
property.

11.  Voting of Shares

  A Participant shall have no interest or voting rights in the Shares until such
time as the Shares are credited to the Participant's Plan Account.  Shares held
for a Participant (or Eligible Employee) in his or her Plan Account will be
voted in accordance with the Participant's (or the Eligible Employee's) express
direction.  In the absence of any such directions such Shares will not be voted.

12.   In-Service Distribution or Sale of Shares

   (a) Sale of Shares.  Subject to the provisions of Paragraph 20 hereof, a
       --------------
Participant may, at any time after the later of the time (i) after the Shares
have been purchased and allocated to the Participant's Plan Account in
accordance with Section 9(a) hereof, or (ii) after the end of the Holding
Period, if any, and without withdrawing from the Plan, by giving notice to the
Administrator, direct the Administrator to sell all or part of the Shares held
on behalf of the Participant.  Upon receipt of such a notice, the Administrator
shall, as soon as practicable after receipt of such notice, sell such Shares and
transmit the net proceeds of such sale (less any bank service fees, brokerage
charges, transfer or withholding taxes, and any other transaction fee, expense
or cost) to the Participant.

   (b) In-Service Share Distributions.  A Participant may, at any time after the
       ------------------------------
later of the time (i) after the Shares have been purchased and allocated to the
Participant's Plan Account in accordance with Section 9(a) hereof, or (ii) after
the end of the Holding Period, if any, and without withdrawing from the Plan,
request that a certificate for all or part of the whole number of Shares held in
his or her Plan Account be sent to him or her as described in Paragraph 9(a)
above.  All such requests must be submitted in writing to the Administrator. The
Administrator may impose a reasonable charge, to be paid by the Participant, for
each stock certificate so issued.

13.  Cessation of Active Participation

  A Participant may during the Enrollment Period, by giving notice to the
Committee or the Employer, in the manner established by the Committee, revoke
his or her authorization for payroll deduction or alternative contribution for
the Election Period to which such authorization relates.  Unless

                                       9
<PAGE>

otherwise required by the applicable Local Law, a Participant may not terminate
his or her participation by revoking his or her authorization for payroll
deduction or alternative contribution or not contributing his or her alternative
contributions for the Election Period after such Election Period has commenced.
If a Participant terminates his or her participation in the Plan during an
Election Period, such termination shall be effective for the next Election
Period, and only if such termination is made by the Participant by giving notice
to the Committee or the Employer in the manner established by the Committee

14.  Termination of Employment or Cessation of Eligibility

  In the event that a Participant ceases to be employed by the Employer for any
reason, including death, disability, retirement or voluntary or involuntary
termination, or ceases to be an Eligible Employee, then the Participant's rights
under the Plan shall terminate.  Except as provided in Paragraph 15, below, the
Company shall as soon as administratively possible, refund to the Participant
without interest  or where required by the applicable Local Law with interest
the payroll deductions or alternative contributions made by the Participant
during the Election Period in which such termination of employment or cessation
of eligibility occurs.

15.  Assignment

  The payroll deductions, or alternative contributions or interest where payable
under the applicable Local Law credited to a Participant's Plan Account, or any
rights to purchase Shares under the Plan may not be assigned, alienated,
transferred, pledged, or otherwise disposed of in any way by a Participant other
than by will or the laws of descent and distribution.  Any such assignment,
alienation, transfer, pledge, or other disposition shall be without effect,
except that the Committee may treat such act as an election to withdraw from the
Plan.  A Participant's right to purchase Shares under this Plan may be
exercisable during the Participant's lifetime only by the Participant.  A
Participant's Plan Account shall be payable to the Participant's estate upon his
or her death in accordance with the applicable laws of death, descent and
distribution.

16.  Adjustment of and Changes in Shares

  If at any time after the effective date of the Plan the Company shall
subdivide or reclassify the Shares with respect to which a purchase right has
been or may be granted under the Plan, or shall declare thereon any stock split
or dividend payable in Shares, or shall alter the capital structure of the
Shares or the Company in any similar manner, then the number and class of Shares
held in the Plan and which may thereafter be subject to the Share purchase right
granted under the Plan (in the aggregate and to any Participant) shall be
adjusted accordingly, and in the case of each right outstanding at the time of
any such action, the number and class of Shares which may thereafter be
purchased pursuant to such right and the Purchase Price shall be adjusted
accordingly, as necessary to preserve the rights of the holder(s) of such Shares
and right(s).

17.  Amendment or Termination of the Plan

  The Committee shall have the right, at any time, to amend, modify or terminate
the Plan without notice; provided, however, that no Participant's existing
rights shall be adversely affected by any such

                                      10

<PAGE>

amendment, modification or termination, except to comply with the applicable
Local Law, stock exchange rules or accounting rules.

  Notwithstanding the foregoing, the Committee shall have the right to terminate
the Plan with respect to all future payroll deductions or alternative
contributions and related purchases at any time.  Such termination of the Plan
shall also terminate any current Election Period in accordance with Paragraph 4
of the Plan.

  Subsidiaries may be added as Designated Subsidiaries by the Committee in its
sole discretion from time to time.

       (ii)  identifying and compiling a list of persons who are Eligible
             Employees for an Election Period;

applicable Local Law of the jurisdiction in which the Employer of the Employee
is located or the Employee is employed or resides.  Prior to the effectiveness
of such registration statement, Shares subject to purchase under the Plan may be
offered to Eligible Employees only pursuant to an exemption from the
registration requirements of the Act and pursuant to any other action that is
required under any applicable Local Law.

22.      No Independent Employees' Rights

  Nothing in the Plan shall be construed to be a contract of employment between
an Employer or its parent or any Subsidiary and any Employee, or any group or
category of Employees (whether for a definite or specific duration or
otherwise), or to prevent the Employer, its parent or any Subsidiary from
terminating any Employee's employment at any time, in accordance with the

exercise of its sole discretion, to establish an earlier date as the last
Trading Day of the Election Period, or to provide that purchase rights shall be
assumed by a successor entity that is a party to the Corporate Transaction or

promptly refund to Participants all payroll deductions or alternative
contributions and interest where payable under the applicable Local Law

purchase made hereunder. With respect to Shares acquired prior to or in
connection with a Corporate Transaction, each Participant will thereafter be
entitled to receive as soon as practicable following the effective date of such
Corporate Transaction the securities or property which a holder of Shares of the
Company was entitled to receive in connection with such Corporate Transaction.

Stock Purchase Plan. Except to the extent modified under this Addendum, all the
provisions of the Plan apply to the Eligible Employees and Participants resident
in France and employed by Designated Subsidiary or Designated Subsidiaries
located in France.

Pursuant to Paragraph 19 of the Plan, the following regulations are made:

1.  Paragraph 2(i) of the Plan to be modified as follows:

    The words "regular fixed basic compensation" in the definition of the term
    "Compensation" under Paragraph 2(i) of the Plan shall be read as "Salaire de
    Base".

2.  Paragraph 2(m) of the Plan to read as follows:

    "(m) "Employee" shall mean an individual who is a full time or part time
         employee of the Employer as defined under Local Law."

3.  Paragraph 2(p) of the Plan to read as follows:

    "(p) "Holding Period" shall mean, the period during which the Participant is
         not permitted to transfer, sell, pledge or otherwise deal in the Shares
         credited to the Participant's Plan Account regardless of the
         termination of any employment contract for whatever reason including
         but not limited to death, disability, or dismissal. The Holding Period
         shall be determined by the Committee in its sole discretion. The
         determination of the Committee may be in respect of Shares credited in
         respect of one or more Election Periods and shall remain in effect
         until changed by the Committee."

4.  Payroll Deduction or Alternative Contribution:

    (I) In respect of Paragraphs 2(k), 2(s) and 2(u); 7; 4(c); 8(a) and (b); 9
        (a); 13; 14; 15; 17; 21; 24 and such other Paragraphs of the Plan, where
        reference is made to "payroll deduction or alternative contribution"
        that reference shall be read as "payroll deduction" only. In other
        words, a Participant shall only be allowed to contribute to the Plan by
        authorizing payroll deductions. Alternative contributions shall not be
        permitted.

5.  Paragraph 2(w) of the Plan to read as follows:

          determined by a financial advisor or appraiser, as selected by the
          Committee or Employer in their sole and absolute discretion, taking
          into account the Holding Period. The fair value of a Share, that is
          subject to the Holding Period, shall approximate a value not less than
          eighty five (85%) of the Closing Value on the last Trading Day of the
          Election Period for Shares that bare no Holding Period and are freely
          tradable. Such date, for the purposes of this Addendum, being deemed
          to be the date the right to purchase such Shares granted to each
          Eligible Employee was

                                      C-1

    Account will not be purchased from the open market on the date the
    Participant exercises such rights.

7.  Paragraph 12 of the Plan to read as follows:

    "12. In-Service Sale or Distribution of Shares

         Eligible Employees under the Plan:

         (i)  Any Employee who would own more than five (5) percent of the
              common stock in the Company immediately after the Share purchase
              opportunity is granted to them under the Plan. Shares that the

              other share-based compensation plan of the Company shall be
              treated as stock owned by the Employee for such purposes, even
              though the option is not presently exercisable or the Shares are
              not presently receivable by the Employee;

         (ii) Employees who are subject to Section 16(a) of the 1934 Act."

3.  Paragraph 2(m) of the Plan to read as follows:

<PAGE>

         (iii) an individual who has been hired on a temporary contract but who
               is expected to fill a permanent staffing need."

         not permitted to transfer, sell, pledge or otherwise deal in the Shares
         credited to the Participant's Plan Account regardless of the
         termination of any employment contract for whatever reason including
         but not limited to death, disability, or dismissal. The Holding Period
         shall be determined as the period of time beginning on the last day the
         Shares are assigned to the Participant and ending the same day of the
         third subsequent year."

5.  Paragraph 2(w) of the Plan to read as follows:

    "(w) "Purchase Price" shall mean, for each Share purchased in accordance
         with Paragraph 9 of the Plan, an amount equal to any percentage figure
         from eighty-five percent (85%) to one-hundred percent (100%), as
         approved by the Committee, of the Closing Value on the last Trading
         Day of the Election Period, which for the Plan purposes shall be
         deemed to be the date the right to purchase such Shares granted to
         each Eligible Employee was exercised.

         However, the Committee may in its sole discretion determine that the
         total Fiscal Value of Discount with respect to all Shares credited to
         a Participant's Plan Account under the Plan in any one calendar year
         shall be limited to four million (4.000.000) Lira or Euro equivalent
         of four million (4.000.000) Lira, or such other amount as it may
         determine.

         The total Fiscal Value of Discount should be determined as the
         difference between the Purchase Price and the arithmetical average of
         the closing sales prices for such Share (or the closing bid, if no
         sales were reported) as quoted on the New York Stock Exchange, or such
         other established stock exchange or national market system on which
         the Share is listed or traded, for the Last Month before ending on the
         day in which Shares are assigned to the Participant.

         For the purposes of this definition, Last Month shall mean the period
         of time ending on the date of determination and beginning on the same
         day of the preceding month. The Share prices (or the closing bid
         price) on the date of determination and on the same day of the
         preceding month are included in the determination. If in this Last
         Month period there is no one Share price (or closing bid price) on the
         Stock Exchange, or such other established stock exchange or national
         market system on which the Share is listed or traded, Last Month shall
         mean the period of time ending on the same day of the month preceding
         the date of the determination and beginning on the same day of the two
         months preceding the last day of the Election Period.

         The Purchase Price as determined hereunder may be in respect of one or
         more Election Periods and shall remain in effect until changed by the
         Committee.

                                      F-2
<PAGE>

          In no event, however, may the Committee select a Purchase Price that
          would be lower than that allowed under Section 423(b)(6) of the Code
          or any successor section."

6.  Paragraph 8(a) of the Plan to read as follows:

      "8(a) Payroll Deduction or Alternative Contribution.  Except as otherwise
       ---------------------------------------------------
    specifically provided herein, the Purchase Price will be payable by each
    Participant by means of payroll deduction. The payroll deduction shall be in
    increments of one percent (1%). Unless otherwise authorized by the
    Committee, the minimum payroll deduction permitted shall be an amount equal
    to two percent (2%) of a Participant's Compensation and the maximum payroll
    deduction contribution shall be an amount equal to fifteen percent (15%) of
    a Participant's Compensation. In any event, the total payroll deduction
    permitted to be made by any Participant in any calendar year shall be
    limited to the lower of (i) Lira 22.666.000 (Lira 22.666 million) or Euro
    equivalent of Lira 22.666 million or (ii) legal currency equivalent of U.S.
    $25,000 as defined under Section 423 (b)(8)(C) of the Code, or such other
    amount as Section 423(b)(8)(C) of the Code, or any successor section, may
    hereafter allow. The actual percentage of Compensation to be deducted or
    contributed shall be specified by a Participant in his or her authorization
    to participate in the Plan. Unless otherwise authorized by the Committee,
    Participants may not deposit any separate cash payments into their Plan
    Accounts.

    Payroll deductions will commence with the first payroll issued during the
    Election Period and will, except as otherwise provided herein, continue with
    each payroll throughout the entire Election Period, except for pay periods
    for which such Participant receives no Compensation. A pay period which ends
    at such time that it is administratively impracticable to credit any payroll
    for such pay period to the then current Election Period will be credited in
    its entirety to the immediately subsequent Election Period. A pay period
    that overlaps Election Periods will be credited in its entirety to the
    Election Period in which it is paid. Alternative contributions will be made
    in accordance with the procedure established by the Committee."

7.  Paragraph 12 of the Plan to read as follows:

     "(a)  Sale of Shares.  Subject to the provisions of Paragraph 20 of the
           --------------
    Plan, a Participant may at any time after the end of the Holding Period as
    defined under Section 4 of this Addendum and without withdrawing from the
    Plan, by giving notice to the Administrator, direct the Administrator to
    sell all or part of the Shares held on behalf of the Participant. Upon
    receipt of such a notice, the Administrator shall, as soon as practicable
    after receipt of such notice, sell such Shares in the open market and
    transfer the net proceeds of such sale (less any bank service fees,
    brokerage charges, transfer or withholding taxes, and any other transaction
    fee, expense or cost) to the Participant.

    the Holding Period requirement of Section 4 of this Addendum and without
    withdrawing from the Plan, request that a certificate for all or part of the
    whole number of Shares held in his or her Plan Account be sent to him or
    her. All such requests must be submitted in writing to the Administrator.
    The Administrator may impose a reasonable charge, to be paid by the
    Participant, for each stock certificate so issued."

8.    Paragraph 13 of the Plan to read as follows:

    "13.   Cessation of Active Participation

      A Participant may during the Enrollment Period, by giving notice to the
    Committee or Employer, revoke his or her authorization for payroll deduction
    for the Election Period to which such Enrollment Period relates. A
    Participant may revoke his or her authorization for payroll deduction for
    the Election Period before the end of such Election Period. Except as
    provided in Paragraph 15 of the Plan, the Company shall, as soon as
    administratively possible, refund to the Participant, the payroll deductions
    for the Election Period in which such cessation occurs. Any revocation after
    the end of the Election Period will be valid for the next Election Period."

Paragraph 20 (b) of the Plan to read as follows:

    "(b)  Specific Responsibilities.  The Committee's responsibilities shall
          -------------------------
    include, but shall not be limited to:

          (ii)  identifying and compiling a list of persons who are Eligible
                Employees for an Election Period;

                The Committee may from time to time adopt rules and regulations
                for carrying out the terms of the Plan. Interpretation or

                elects to become, a Participant; and

          (ii)  one hundred percent (100%) of the Closing Value of such Share

     Period may not resume participation

                                      I-2

      rendered on a basis agreed with the Company. A firm or company in which a

7.  MATCHING SHARES
    ---------------

7.1  The Partnership Share Agreement sets out the basis on which a Participant
     is entitled to Matching Shares in accordance with this Part of the Rules.
     General requirements for Matching Shares

7.2  Matching Shares shall:

     (A)  be Shares of the same class and carrying the same rights as the
          Partnership Shares to which they relate;

     (B)  subject to Rule 7.4, be awarded on the same day as the Partnership
          Shares to which they relate are acquired on behalf of the Participant;
          and

     (C)  be awarded to all Participants on exactly the same basis.

     Ratio of Matching Shares to Partnership Shares

7.3  The Partnership Share Agreement shall specify the ratio of Matching Shares
     to Partnership Shares for the time being offered by the Company and that
     ratio shall not exceed 2:1. The Company may vary the ratio before
     Partnership Shares are acquired. Employees shall be notified of the terms
     of any such variation before the Partnership Shares are awarded under the
     Partnership Share Agreement.

7.4  If the Partnership Shares on that day are not sufficient to produce a
     Matching Share, the match shall be made when sufficient Partnership Shares
     have been acquired to allow at least one Matching Share to be appropriated.

     Holding Period for Matching Shares

7.5  The Company shall, in relation to each Award Date, specify a Holding Period
     throughout which a Participant shall be bound by the terms of the
     Partnership Share Agreement.

7.6  The Holding Period shall, in relation to each Award, be a specified period
     of not less than three years nor more than five years, beginning with the
     Award Date and shall be the same for all Participants who receive an Award
     at the same time. The Holding Period shall not be increased in respect of
     Matching Shares awarded under the Plan.

7.7  A Participant may during the Holding Period direct the Trustees:

     (A)  to accept an offer for any of their Matching Shares if the acceptance
          or agreement shall result in a new holding being equated with those
          original Shares for the purposes of capital gains tax; or

     (B)  to accept an offer of a Qualifying Corporate Bond (whether alone or
          with other assets or cash or both) for their Matching Shares if the
          offer forms part of such a general offer as is mentioned in paragraph
          (C); or

     (C)  to accept an offer of cash, with or without other assets, for their
          Matching Shares if the offer forms part of a general offer which is
          made to holders of shares of the same class as their Shares or to the
          holders of shares in the same company, and

                                       21
<PAGE>

          which is made in the first instance on a condition such that if it is
          satisfied the person making the offer shall have control of that
          company, within the meaning of section 416 of ICTA 1988; or

     (D)  to agree to a transaction affecting their Matching Shares or such of
          them as are of a particular class, if the transaction would be entered
          into pursuant to a compromise, arrangement or scheme applicable to or
          affecting:

          (1)  all of the ordinary share capital of the Company or, as the case
               may be, all the shares of the class in question; or

          (2)  all the shares, or all the shares of the class in question, which
               are held by a class of shareholders identified otherwise than by
               reference to their employment or their participation in a plan
               approved under the Schedule.

8.   DIVIDEND SHARES
     ---------------

     Reinvestment of cash dividends

8.1  The Free Share Agreement or Partnership Share Agreement, as appropriate,
     shall set out the rights and obligations of Participants receiving Dividend
     Shares under the Plan.

8.2  The Company may direct that any cash dividend in respect of Plan Shares
     held on behalf of Participants may be applied in acquiring further Plan
     Shares on their behalf.

8.3  Dividend Shares shall be Shares:

     (A)  of the same class and carrying the same rights as the Shares in
          respect of which the dividend is paid; and

     (B)  which are not subject to any provision for forfeiture.

8.4  The Company may decide to:

     (A)  apply all Participants' dividends, up to the limit specified in Rule
          8.6, to acquire Dividend Shares;

     (B)  to pay all dividends in cash to all Participants; or

     (C)  to offer Participants the choice of either (A) or (B) above.

8.5  The Company may revoke any direction for reinvestment of cash dividends.

8.6  The amount applied by the Trustees in acquiring Dividend Shares shall not
     exceed (Pounds)1,500 in each Tax Year. For the purposes of this Rule, the
     Dividend Shares are those acquired under this Plan and those acquired under
     any other plan approved under the Schedule. In exercising their powers in
     relation to the acquisition of Dividend Shares the Trustees must treat
     Participants fairly and equally.

8.7  If the amounts received by the Trustees exceed the limit in Rule 8.6, the
     balance shall be paid to the participant as soon as practicable.

8.8  The Trustees shall apply all the cash dividend to acquire Shares on behalf
     of the Participant on the Acquisition Date. The number of Dividend Shares
     acquired on behalf of each Participant shall be determined by the Market
     Value of the Shares on the Acquisition Date.

     Certain amounts not reinvested to be carried forward

8.9  Subject to Rule 8.7, any amount that is not reinvested:

     (A)  because the amount of the cash dividend is insufficient to acquire a
          Share; or

     (B)  because there is an amount remaining after acquiring the Dividend
          Shares;

     may be retained by the Trustees and carried forward to be added to the
     amount of the next cash dividend to be reinvested.

                                       23
<PAGE>

8.10  If, during the period of three years beginning with the date on which the
      dividend was paid:

      (A)  it is not reinvested; or

      (B)  the Participant ceases to be in relevant employment; or

      (C)  a Plan Termination Notice is issued

      the amount shall be repaid to the Participant as soon as practicable. On
      making such a payment, the Participant shall be provided with the
      information specified in paragraph 90 of the Schedule.

      Holding Period for Dividend Shares

8.11  The Holding Period shall be a period of three years, beginning with the
      Acquisition Date.

8.12  A Participant may during the Holding Period direct the Trustees:

      (A)  to accept an offer for any of their Dividend Shares if the acceptance
           or agreement shall result in a new holding being equated with those
           shares for the purposes of capital gains tax; or

      (B)  to accept an offer of a Qualifying Corporate Bond (whether alone or
           with other assets or cash or both) for their Dividend Shares if the
           offer forms part of such a general offer as is mentioned in paragraph
           (C); or

      (C)  to accept an offer of cash, with or without other assets, for their
           Dividend Shares if the offer forms part of a general offer which is
           made to holders of shares of the same class as their shares or to
           holders of shares in the same company, and which is made in the first
           instance on a condition such that if it is satisfied the person
           making the offer shall have control of that company, within the
           meaning of section 416 of ICTA 1988; or

      (D)  to agree to a transaction affecting their Dividend Shares or such of
           them as are of a particular class, if the transaction would be
           entered into pursuant to a compromise, arrangement or scheme
           applicable to or affecting:

           (1)  all of the ordinary share capital of the Company or, as the case
                may be, all the shares of the class in question; or

           (2)  all the shares, or all the shares of the class in question,
                which are held by a class of shareholders identified otherwise
                than by reference to their employment or their participation in
                a plan approved under the Schedule.

8.13  Where a Participant is charged to tax in the event of their Dividend
      Shares ceasing to be subject to the Plan, they shall be provided with the
      information specified in paragraph 93(4) of the Schedule.

<PAGE>

     (A)  a transaction which results in a new holding (referred to in this Rule
          as "the New Holding") being equated with the Original Holding for the
          purposes of capital gains tax; or

     (B)  a transaction which would have that result but for the fact that what
          would be the new holding consists of or includes a Qualifying
          Corporate Bond.

9.2  If an issue of Shares of any of the following description (in respect of
     which a charge to income tax arises) is made as part of a company
     reconstruction, those Shares shall be treated for the purposes of this Rule
     as not forming part of the New Holding:

     (A)  redeemable shares or securities issued as mentioned in section
          209(2)(c) of ICTA 1988;

     (B)  share capital issued in circumstances such that section 210(1) of ICTA
          1988 applies; or

     (C)  share capital to which section 249 of ICTA 1988 applies.

9.3  In this Rule:

     "Corresponding Shares" in relation to any New Shares, means the Shares in
     respect of which the New Shares are issued or which the New Shares
     otherwise represent;

     "New Shares" means shares comprised in the New Holding which were issued in
     respect of, or otherwise represent, shares comprised in the Original
     Holding.

9.4  Subject to the following provisions of this Rule, references in this Plan
     to a Participant's Plan Shares shall be respectively construed, after the
     time of the company reconstruction, as being or, as the case may be, as
     including references to any New Shares.

9.5  For the purposes of the Plan:

     (A)  a company reconstruction shall be treated as not involving a disposal
          of Shares comprised in the Original Holding; and

     (B)  the date on which any New Shares are to be treated as having been
          appropriated to or acquired on behalf of the Participant shall be that
          on which Corresponding Shares were so appropriated or acquired.

9.6  In the context of a New Holding, any reference in this Rule to shares
     includes securities and rights of any description which form part of the
     New Holding for the purposes of Chapter II of Part IV of the Taxation of
     Chargeable Gains Act 1992.

10.  RIGHTS ISSUES
     -------------

10.1  Any shares or securities allotted under clause 12 of the Trust Deed shall
      be treated as Plan Shares identical to the shares in respect of which the
      rights were conferred. They shall be treated as if they were awarded to or
      acquired on behalf of the Participant under the Plan in the same way and
      at the same time as those shares.

10.2  Rule 10.1 does not apply:

      (A)  to shares and securities allotted as the result of taking up a rights
           issue where the funds to exercise those rights were obtained
           otherwise than by virtue of the Trustees disposing of rights in
           accordance with this rule; or

      (B)  where the rights to a share issue attributed to Plan Shares are
           different from the rights attributed to other ordinary shares of the
           company.

Rights and Obligations

1.  I agree that taking part in the Plan does not affect my rights, entitlements
    and obligations under my contract of employment, and does not give me any
    rights or additional rights to compensation or damages if my employment
    ceases.

2.  I may stop the deductions at any time, or begin them again, by writing to my
    employer, but I may not make up any amounts missed when deductions were
    stopped.

    receive may be scaled down if the limit on the number of shares set by the
    Company for this award is exceeded.

4.  I may ask the Trustees for my Partnership Shares at any time, but I may have
    to pay income tax and National Insurance Contributions when they are taken
    out of the Plan.

5.  I agree to allow the Trustees to sell some or all of my shares to pay any
    income tax and National Insurance Contributions in respect of my shares
    ceasing to be subject to the Plan, unless I provide them in advance with

6.  I agree that any deductions not used to buy shares will at the discretion of
    the Trustees be repaid to me after the deduction of any necessary income tax
    or National Insurance Contributions, or will be carried forward and added to
    the next deduction or Accumulation Period.

7.  If there is a rights issue, I agree to allow the Trustees to sell some of
    the rights attached to my shares in the Plan, in order to fund the exercise
    of the rights attached to other shares held by me in the Plan.

8.  I can at any time withdraw from this agreement by writing to my employer.
    Any unused deductions will be returned to me after the deduction of any
    necessary income tax or National Insurance Contributions.
