Exhibit 10.2
W.W. GRAINGER, INC.
2015 Incentive Plan
Form of Stock Option Agreement

This Stock Option Agreement (this "Agreement"), dated as of , 20 (the "Grant
Date"), is entered into between W.W. Grainger, Inc., an Illinois corporation
(the "Company"), and you as the executive (the "Executive"), who is employed by
the Company or a Subsidiary of the Company (the "Employer").

In consideration of the Executive's agreement to enter into an Unfair
Competition Agreement with the Company concurrently with this Agreement on the
Grant Date (the "Unfair Competition Agreement"), the Company desires to grant
the Executive the right and option ("Option") to purchase shares of the
Company's common stock ("Shares") pursuant to the W.W. Grainger, Inc. 2015
Incentive Plan (as may be amended from time to time, the "Plan") and the
Executive desires to enter into the Unfair Competition Agreement and accept such
Option on the terms and conditions set forth in this Agreement, the Plan and the
Unfair Competition Agreement. Capitalized terms used but not defined in this
Agreement have the meanings specified in the Plan.

In consideration of the mutual provisions set forth in this Agreement and in the
Unfair Competition Agreement, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

ARTICLE I
Grants

1.1    Grants. Subject to the terms and conditions of this Agreement, the Plan
and the Unfair Competition Agreement (the terms of which are hereby incorporated
herein by reference) and effective on the Grant Date, the Company hereby grants
to the Executive the Option to purchase all or a portion of the number of Shares
specified in the , 20 award grant at the price per Share as specified in the
grant notice posted to the Executive's electronic investment account maintained
with the brokerage firm/third party service provider engaged by the Company in
connection with the operation of the Plan (the "Administrator").

1.2    Term of Option. The Option shall expire ten (10) years from the Grant
Date (i.e., a grant on , 20 would expire on , 20 ), subject to the terms and
conditions set forth in this Agreement, the Plan and the Unfair Competition
Agreement.

ARTICLE II
Provisions Relating to Option

2.1    Vesting of Option. If the Executive remains continuously employed by the
Employer (or any other Subsidiary or Affiliate) until the vesting date specified
in the grant notice (the "Option Vesting Date"), the Option shall become fully
vested and exercisable on such date. The Option shall not vest before the Option
Vesting Date unless otherwise provided or permitted by the Plan or this
Agreement, and any portion of the Option that does not vest shall be forfeited
in full and the Executive shall have no further rights with respect to such
Option.

2.2    Effect of Termination of Employment. If the Executive's employment or
service is terminated prior to the Option Vesting Date for any reason whatsoever
other than the Executive's death or Disability (defined below), the Executive
shall cease vesting in the Option as of the Executive's Termination Date
(defined below) and the Option shall be forfeited in its entirety. In addition,
the Executive shall have three (3) months from the Termination Date to exercise
vested Options. If the Executive is a resident of, or employed in, the United
States, "Termination Date" shall mean the effective date of termination of the
Executive's employment. If the Executive is a resident of, or employed outside
of, the United States, "Termination Date" shall mean the earliest of (i) the
date on which notice of termination is provided to the Executive, (ii) the last
day of the Executive's active service with the Employer or (iii) the last day on
which the Executive is an employee of the Employer, as determined in each case
without including any required advanced notice period and irrespective of the
status of the termination under local labor or employment laws.

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

2.3    Effect of Death or Disability of the Executive.    If the Executive's
employment or service is terminated prior to the Option Vesting Date due to the
Executive's death or Disability, the Option immediately shall fully vest, become
exercisable and will expire on the earlier of (i) six (6) years from the
Termination Date or (ii) the original expiration date of the Option. For
purposes of this Agreement, "Disability" shall have the same meaning as defined
in the Plan, subject to modification as may be required to conform to the laws,
rules and regulations (“Laws”) of the Executive's country of residence (and
country of employment, if different).

2.4    Exercise of Option. The Executive may exercise the vested portion of the
Option in accordance with such policies and procedures as shall be established
by the Company and/or the Administrator from time to time.

2.5    Payment of Option Price. The Executive shall at the time of exercise of
the Option (except in the case of a cashless exercise) tender to the Company the
full Option Price. At the discretion of the Committee, and subject to such
policies and procedures as it may adopt from time to time, the Option Price may
be paid (i) in cash, (ii) in Shares already owned by the Executive for at least
six (6) months and having a Fair Market Value on the date of exercise equal to
the Option Price, (iii) through a combination of cash and Shares, or (iv)
through a cashless exercise through a broker-dealer approved for this purpose by
the Company. Notwithstanding anything to the contrary in this Agreement, if the
Executive resides in a country where the local foreign exchange Laws either
preclude the remittance of currency out of the country for purposes of paying
the Option Price, or require the Company, the Employer and/or the Executive to
secure any legal or regulatory approvals, complete any legal or regulatory
filings, or undertake any additional steps for remitting currency out of the
country, the Company may restrict the method of exercise to a form of cashless
exercise or such other form(s) of exercise as it determines in its sole
discretion.

ARTICLE III
Recoupment

3.1    Recoupment in Event of Misconduct. If the Board of Directors of the
Company (the "Board") determines that the Executive has committed fraud against
the Company or has engaged in any criminal conduct that involves or is related
to the Company and such Executive is otherwise entitled to receive performance
shares, stock options, restricted stock units or cash incentive compensation
(collectively, "Incentive Compensation"), then the Company shall have the right
to recover and the Executive shall be obligated to return such Incentive
Compensation, in whole or in part, for any period of time, as it deems
appropriate under the circumstances. The Board shall have sole discretion in
determining whether the Executive's conduct was in compliance with applicable
Law or Company policy and the extent to which the Company will seek recovery of
the Incentive Compensation notwithstanding any other remedies available to the
Company. If the Executive engages in misconduct or is believed to have engaged
in misconduct, including but not limited to any violation of any of Executive's
obligations under the Unfair Competition Agreement, the Company shall be
entitled to recover from the Executive, and the Executive shall re-pay any
Incentive Compensation received pursuant to the Plan and this Agreement, in
whole or in part, for any period of time, as the Company deems appropriate under
the circumstances.

3.2    Recoupment in Event of Materially Inaccurate Financial Results. If the
Company has publicly filed materially inaccurate financial results (the "Subject
Financials"), whether or not they result in a restatement, the Board has the
discretion to recover any Incentive Compensation that was paid or settled to the
Executive during the period covered by the Subject Financials as set forth
herein. If the payment or settlement of Incentive Compensation would have been
lower had the achievement of applicable financial performance goals been
calculated based on restated financial results with respect to the Subject
Financials, the Board may, if it determines appropriate in its sole discretion,
recover the portion of the paid or settled Incentive Compensation in excess of
the payment or settlement that would have been made based on restated financial
results. The Company will not seek to recover Incentive Compensation received or
settled more than three (3) years after the date of the initial filing that
contained the Subject Financials.

3.3    Implementation. For purposes of this Article III, the Executive expressly
authorizes the Company to issue instructions, on behalf of the Executive, to the
Administrator (and/or any other brokerage firm/third party service provider
engaged by the Company to hold Shares and other amounts acquired under the Plan)
to reconvey, transfer or otherwise return to the Company any Incentive
Compensation subject to recoupment hereunder. Executive acknowledges and agrees
that the Company's rights hereunder shall not be affected in any way by any
subsequent change in the Executive’s status, including retirement or termination
of employment.

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

3.4    Forfeiture. To the extent any of the events set forth in Sections 3.01 or
3.02 occur before the Executive receives any Incentive Compensation due
hereunder, any such Incentive Compensation shall be forfeited as determined by
the Company in its sole discretion.

ARTICLE IV
Tax

4.1    Tax-Related Items. Regardless of any action the Company or the Employer
takes with respect to any or all income tax (including U.S. federal, state and
local taxes or non-U.S. taxes), social insurance, payroll tax, payment on
account or other tax-related withholding ("Tax-Related Items"), the Executive
acknowledges and agrees that the ultimate liability for all Tax-Related Items
legally due by the Executive is and remains the Executive's responsibility and
that the Company and the Employer (i) make no representations or undertakings
regarding the treatment of any Tax-Related Items in connection with any aspect
of the Option, including the grant of the Option, the vesting of the Option, the
exercise of the Option, the subsequent sale of any Shares acquired pursuant to
the Option and the receipt of any dividends and (ii) do not commit to structure
the terms of the grant or any aspect of the Option to reduce or eliminate the
Executive's liability for Tax-Related Items.

4.2    Tax Withholding Obligations. Prior to the delivery of Shares upon the
exercise of the Option, if the Executive's country of residence (and country of
employment, if different) requires withholding of Tax-Related Items, the Company
shall withhold a sufficient number of whole Shares otherwise issuable upon
exercise of the Option that have an aggregate Fair Market Value sufficient to
pay the Tax-Related Items required to be withheld with respect to the Shares.
Depending on the withholding method specified in the Plan, the Company may
withhold or account for Tax-Related Items by considering applicable minimum
statutory withholding rates or other applicable withholding rates, including
maximum applicable rates, in which case the Company shall make a cash payment to
the Executive equal to the over-withheld amount as soon as administratively
practicable. The cash equivalent of the Shares withheld will be used to settle
the obligation to withhold the Tax-Related Items. In the event that withholding
in Shares is prohibited under applicable Law or otherwise may trigger adverse
consequences to the Company or the Employer, the Company and the Employer may
withhold the Tax- Related Items required to be withheld with respect to the
Shares in cash from the Executive's regular salary and/or wages or any other
amounts payable to the Executive. In the event the withholding requirements are
not satisfied through the withholding of Shares by the Company or through the
withholding of cash from the Executive's regular salary and/or wages or other
amounts payable to the Executive, no Shares will be issued to the Executive (or
the Executive's estate) upon the exercise of the Option unless and until
satisfactory arrangements (as determined by the Committee) have been made by the
Executive with respect to the payment of any Tax-Related Items that the Company
or the Employer determines, in its sole discretion, must be withheld or
collected with respect to such Option. If the obligation for the Executive's
Tax-Related Items is satisfied by withholding a number of Shares as described
herein, the Executive shall be deemed to have been issued the full number of
Shares issuable upon exercise, notwithstanding that a number of the Shares is
held back solely for the purpose of paying the Tax-Related Items due as a result
of the exercise or any other aspect of the Award.

The Executive will pay to the Company or the Employer any amount of Tax- Related
Items that the Company or the Employer may be required to withhold as a result
of the Executive's participation in the Plan or the Executive's acquisition of
Shares that cannot be satisfied by the means described in this Article IV. The
Company may refuse to deliver any Shares due upon exercise of the Option if the
Executive fails to comply with his or her obligations in connection with the
Tax-Related Items as described herein. If the Executive is subject to taxation
in more than one jurisdiction, the Executive acknowledges that the Company, the
Employer or one or more of their respective Subsidiaries may be required to
withhold or account for Tax-Related Items in more than one jurisdiction. The
Executive hereby consents to any action reasonably taken by the Company and the
Employer to meet his or her obligation for Tax-Related Items. By accepting this
grant of Option, the Executive expressly consents to the withholding of Shares
and/or withholding from the Executive's regular salary and/or wages or other
amounts payable to the Executive as provided for hereunder. All other
Tax-Related Items related to the Option and any Shares delivered in payment
thereof are the Executive's sole responsibility.

ARTICLE V
International Arrangements

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

5.1    Exchange Controls. As a condition to this grant of Options, the Executive
agrees to comply with any applicable foreign exchange Laws and hereby consents
to any necessary, appropriate or advisable actions taken by the Company, the
Employer or any of their respective Subsidiaries as may be required to comply
with any applicable Laws of the Executive's country of residence (and country of
employment, if different).

5.2    Foreign Asset and Account Reporting Requirements. The Executive
acknowledges that there may be certain foreign asset and/or account reporting
requirements which may affect the Executive's ability to acquire or hold Shares
acquired under the Plan or cash received from participating in the Plan
(including from any dividends or dividend equivalent payments) in a brokerage or
bank account outside the Executive's country of residence (and country of
employment, if different). The Executive may be required to report such
accounts, assets or transactions to the tax or other authorities in the
Executive's country of residence (and country of employment, if different). The
Executive acknowledges and agrees that it is his or her personal responsibility
to be compliant with such Laws.

5.3    Country Specific Addendum. Notwithstanding any provisions of this
Agreement to the contrary, the Option shall be subject to any special terms and
conditions for the Executive's country of residence (and country of employment,
if different) set forth in the addendum to this Agreement ("Addendum"). If the
Executive transfers residence and/or employment to another country reflected in
an Addendum at the time of transfer, the special terms and conditions for such
country will apply to the Executive to the extent the Company determines, in its
sole discretion, that the application of such special terms and conditions is
necessary or advisable in order to comply with local Laws or to facilitate the
operation and administration of the Option and the Plan (or the Company may
establish alternative terms and conditions as may be necessary or advisable to
accommodate the Executive's transfer). In all circumstances, any applicable
Addendum shall constitute part of this Agreement.

5.4    Controlling Language. The Executive acknowledges and agrees that it is
the Executive's express intent that this Agreement, the Plan, the Unfair
Competition Agreement and all other documents, notices and legal proceedings
entered into, given or instituted pursuant to the Option be drawn up in English.
If the Executive has received this Agreement, the Plan, the Unfair Competition
Agreement or any other documents related to the Option translated into a
language other than English and the meaning of any translated version is
different than the English version, the English version will control.

ARTICLE VI
Miscellaneous

6.1    Restriction on Transferability. Except to the extent expressly provided
in the Plan or this Agreement, the Option may not be sold, transferred, pledged,
assigned, or otherwise alienated at any time other than by will or by the laws

hereof shall be null and void.

6.2    Rights as Shareholder. The Executive shall not have voting or any other
rights as a shareholder of the Company with respect to the Shares issuable upon
exercise of the Option until the date of issuance of such Shares. Upon exercise
of the Option the Executive will obtain, with respect to the Shares received in
such exercise, full voting and other rights as a shareholder of the Company.

6.3    Administration. The Committee shall have the power to interpret the Plan
and this Agreement and to adopt such rules for the administration,
interpretation, and application of the Plan as are consistent therewith and to
interpret or revoke any such rules. All actions taken and all interpretations
and determinations made by the Committee shall be final and binding upon the
Executive, the Company, and all other Persons. No member of the Committee shall
be personally liable for any action, determination, or interpretation made in
good faith with respect to the Plan or this Agreement.

6.4    No Employment Rights. This Agreement and the Executive's participation in
the Plan are not and shall not be interpreted to: (i) form an employment

the employ of the Company, the Employer or any of their respective Subsidiaries;
or (iii) interfere with the ability of the Company, the Employer or any of their

6.5    Nature of Grant. In accepting the grant hereunder, the Executive
acknowledges and agrees that: (i) the Plan is established voluntarily by the
Company, it is discretionary in nature and it may be modified, amended,

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

suspended or terminated by the Company at any time; (ii) the Executive has read
the Plan and any Options granted under it shall be subject to all of the terms
and conditions of the Plan, including but not limited to the power of the

the Company, the Employer nor any of their respective Subsidiaries shall be
liable for any change in value of the Option, the amount realized upon
settlement of the Option or the amount realized upon a subsequent sale of any
Shares acquired upon exercise of the Option, resulting from any fluctuation of
the United States Dollar/local currency foreign exchange rate. Without limiting
the generality of the foregoing, the Committee shall have the discretion to
adjust the terms and conditions of any Option to correct for any windfalls or
shortfalls in such Option which, in the Committee's determination, arise from
factors beyond the Executive's control; provided, however, that the Committee's
authority with respect to any Option to a "covered employee," as defined in

requirements) and compliance with the Laws and practices of any stock exchange
upon which the Shares are listed. If the Executive resides or is employed
outside of the United States, the Executive agrees, as a condition of the grant
of the Option, to repatriate all payments attributable to the Shares and/or cash
acquired under the Plan (including, but not limited to, dividends and any

required by and in accordance with local Laws in the Executive’s country of
residence (and country of employment, if different). In addition, the Executive
also agrees to take any and all actions, and consent to any and all actions

states that it is amending this Agreement executed by (i) the Company and the
Executive, (ii) the Company (at the discretion of the Committee), so long as a
copy of such amendment is delivered to the Executive, and provided that no such
amendment adversely affecting the rights of the Executive hereunder may be made
without the Executive's written consent or
(iii) the Company (at the discretion of the Committee) in any way it may deem
necessary or advisable to carry out the purpose of the grant as a result of any
change in applicable Laws or any future Laws or judicial decisions.

notice shall have been deemed given when actually delivered.

6.9    Severability. If all or any part of this Agreement or the Plan is
declared by any court or governmental authority to be unlawful or invalid, such
unlawfulness or invalidity shall not invalidate any portion of this Agreement or
the Plan not declared to be unlawful or invalid. Any provision of this Agreement
(or part of such provision) so declared to be unlawful or invalid shall, if
possible, be construed in a manner which will give effect to the terms of such
provision (or part of such provision) to the fullest extent possible while

Option) of the Plan. The Option is subject to the terms of the Plan. The
Executive acknowledges receipt of the Plan booklet which contains the entire
Plan, and the Executive represents and warrants that the Executive has read the
Plan. Additional copies of

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

the Plan are available upon request during normal business hours at the

VOLUNTARILY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR

AGREEMENT.

6.12    Waiver; No Third Party Beneficiaries. A waiver by the Company of a
breach of any provision of this Agreement by the Executive shall not operate or
be construed as a waiver of any other provision of this Agreement, or of any
subsequent breach by the Executive. This Agreement shall not be construed to
create any third party beneficiary rights.

6.13    Data Privacy.

(i)Pursuant to applicable personal Data (defined below) protection laws, the
collection, use, processing and transfer of the Executive's personal Data is
necessary for the Company's administration of the Plan and the Executive's
participation in the Plan. The Executive expressly and voluntarily (a)
acknowledges, consents and agrees to the collection, use, processing and/or
transfer of personal Data as described herein; (b) authorizes the Company, its
Subsidiaries and the Employer to transfer Data, in electronic or other form, to
each other and to any third parties, including the subsequent holding of Shares
on the Executive's behalf to a broker or other third party with whom the
Executive may elect to deposit any Shares acquired pursuant to the Plan, to
assist the Company in the implementation, administration and management of the
Plan. These recipients may be located throughout the world. For purposes of this
Section 6.13, "Data" means certain personal information about the Executive
including (but not limited to) the Executive's name, home address and telephone
number, date of birth, social security number or other employee identification
number, email address, salary, nationality, job title, any Share ownership and
details of any Award or any other entitlement to Shares awarded, canceled,
purchased, vested, unvested or outstanding in the Executive's favor for the
purpose of managing and administering the Plan.

(ii)Data may be provided by the Executive or collected, where lawful, from third
parties. The Company, its Subsidiaries, the Employer and any third party service
providers will process the Data collected hereunder for the purpose of
implementing, administering and managing the Executive's participation in the
Plan. Data processing will take place through electronic and non-electronic
means in accordance with applicable Law and the Company, its Subsidiaries and
the Employer's policies and procedures as in effect from time to time. The
Executive may, at any time, seek to exercise his or her rights provided under
applicable personal Data protection laws by contacting his or her local human
resources manager.

6.14    Private Placement. The grant of the Option is not intended to be a
public offering of securities in the Executive's country of residence (and
country of employment, if different). The Company has not submitted any
registration statement, prospectus or other filing with the local securities
authorities (unless otherwise required under local Laws).

6.15    No Advice Regarding Grant. Neither the Company nor the Employer is
providing any tax, legal or financial advice, nor is the Company nor the
Employer making any recommendations regarding the Option, the Executive's
participation in the Plan or the Executive's acquisition or sale of the
underlying Shares. The Executive is hereby advised to consult with the
Executive's own personal tax, legal and financial advisors regarding
participation in the Plan before taking any action related to the Plan.

6.16    Securities Law Restrictions. The Executive acknowledges that, depending
on the Executive's country of residence (and country of employment, if
different), the Executive may be subject to insider trading restrictions and/or
market abuse Laws, which may affect the Executive's ability to acquire or sell
Shares or rights to Shares (e.g., the Option) under the Plan during such times
as the Executive is considered to have "inside information" regarding the
Company or its business (as defined by the local Laws in the Executive's country
of residence and/or employment). Any restrictions under these Laws are separate
from and in addition to any restrictions that may

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

be imposed under any applicable Company insider trading or other policy. The
Executive solely is responsible for ensuring compliance with any applicable
restrictions and should consult with his or her personal legal advisor on this
matter.

6.17    Stock Ownership and Retention Guidelines. The exercise of any Options is
subject to the Company's Stock Ownership and Retention Guidelines, as in effect
from time to time, in all respects.

6.18    EU Age Discrimination Rules. If the Executive is a local national of and
employed in a country that is a member of the European Union, the grant of the
Option and the terms and conditions governing the Option are intended to comply
with the age discrimination provisions of the EU Equal Treatment Framework
Directive, as implemented into local law (the "Age Discrimination Rules"). To
the extent that a court or tribunal of competent jurisdiction determines that
any provision of this Agreement is invalid or unenforceable, in whole or in
part, under the Age Discrimination Rules, the Company, in its sole discretion,
shall have the power and authority to revise or strike such provision to the
minimum extent necessary to make it valid and enforceable to the full extent
permitted under local Laws.

6.19    Electronic Delivery. The Company may, in its sole discretion, deliver
any documents related to the Option or other Awards granted to the Executive
under the Plan by electronic means. The Executive hereby expressly consents to
receive such documents by electronic delivery and agrees to participate in the
Plan through an online or electronic system established and maintained by the
Company or a third party designated by the Company.

6.20    Governing Law; Jurisdiction. This Agreement shall be exclusively
governed by, and construed in accordance with, the Laws of the State of Illinois
without giving effect to any choice of law or conflict of law rules or
provisions (whether of the State of Illinois or of any other jurisdiction) that
would cause the application of the laws of a jurisdiction other than the State
of Illinois. All disputes and controversies arising between the parties are to
be submitted for determination exclusively to the federal or state courts of the
State of Illinois and by accepting the grant of the Option, the Executive
expressly consents to the jurisdiction of such courts. Notwithstanding the
foregoing, the Company may at its option seek interim and permanent injunctive
relief before any competent court, tribunal or judicial forum, which in the
absence of the foregoing provision, would have jurisdiction to grant the relief
sought.

6.21    Entire Agreement. The Plan, this Agreement (including any applicable
addendum) and the Unfair Competition Agreement constitute the entire agreement
of the parties with respect to the subject matter hereof and supersede, in their
entirety, all prior undertakings and agreements of the Company and the Executive
with respect to the subject matter hereof.

Data Privacy Notice and Consent

This provision supplements Section 6.13 of the Agreement:

The Executive hereby authorizes the Company, its Subsidiaries and the Employer
to discuss with and obtain all relevant information pertaining to the Executive
from all personnel involved in the administration and operation of the Plan. The
Executive further authorizes the Company, its Subsidiaries and the Employer to
disclose and discuss the Executive's participation in the Plan with their
advisors. The Executive further authorizes the Company, its Subsidiaries and the
Employer to record any information pertaining to the Executive’s participation
in the Plan and to keep such information in his or her employee file.

Accelerated Vesting upon Retirement

Notwithstanding anything in the Agreement or the Plan to the contrary, if the
Executive’s employment or service is terminated by reason of retirement, the
Option immediately shall fully vest, become exercisable and will expire on the
earlier of (i) six (6) years from the Termination Date or (ii) the original
expiration date of the Option. For purposes of the foregoing, “retirement” shall
have the definition prescribed by local Laws.

No Exercise Using Previously Owned Shares

Notwithstanding any provision in the Agreement or the Plan to the contrary, the
Executive may not pay the Option Price by tendering Shares already owned by the
Executive.

Securities Law Information

The Executive is permitted to sell Shares acquired through the Plan through the
designated broker appointed under the Plan, if any, provided that the resale of
such Shares takes place outside of Canada through the facilities of a stock
exchange on which the Shares are listed (i.e., the New York Stock Exchange).

Foreign Asset Reporting Information

Any foreign property (including Shares and Options acquired under the Plan) must
be reported to the Canada Revenue Agency on form T1135 (Foreign Income
Verification Statement) if the total cost of your foreign property exceeds
C$100,000 at any time in the year. The Options must be reported - generally at a
nil cost - if the C$100,000 cost threshold is exceeded because of other foreign
property held. If Shares are acquired, their cost generally is the adjusted cost
base (“ACB”) of the Shares. The ACB would normally equal the fair market value
of the Shares at time of exercise, but if the Executive owns other Shares, this
ACB may have to be averaged with the ACB of the other Shares. The form must be
filed by April 30 of the following year. The Executive should consult with his
or her personal tax advisor to determine the Executive’s reporting requirements.

Accelerated Vesting upon Retirement

Notwithstanding anything in the Agreement or the Plan to the contrary, if the
Executive’s employment or service is terminated by reason of retirement, the
Option immediately shall fully vest, become exercisable and will expire on the
earlier of (i) six (6) years from the Termination Date or (ii) the original
expiration date of the Option. For purposes of the foregoing, “retirement” shall
have the definition prescribed by local Laws.

Commercial Relationship

The Executive expressly recognizes that participation in the Plan and the
Company’s grant of the Option does not constitute an employment relationship
between the Executive and the Company. The Executive has been granted the Option
as a consequence of the commercial relationship between the Company and the
Employer, and the Employer is the Executive’s sole employer. Based on the
foregoing, (a) the Executive expressly recognizes that the Plan and the benefits
derived from participation in the Plan do not establish any rights between the
Executive and the Company or the Employer, (b) the Plan and the benefits derived
from participation in the Plan are not part of the employment conditions and/or
benefits provided by the Company or the Employer, and (c) any modifications or
amendments to the Plan by the Company, or a termination of the Plan by the
Company, shall not constitute a change or impairment of the terms and conditions
of the Executive’s employment with the Employer.

Extraordinary Item of Compensation

The Executive expressly acknowledges and agrees that participation in the Plan
is a result of the discretionary and unilateral decision of the Company, as well
as the Executive’s free and voluntary decision to participate in the Plan in
accord with the terms and conditions of the Plan, the Agreement, the Unfair
Competition Agreement and this Addendum. As such, the Executive acknowledges and
agrees that the Company may, in its sole discretion, amend

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

and/or discontinue the Executive’s participation in the Plan at any time and
without any liability. The value of the Option is an extraordinary item of
compensation outside the scope of the employment contract, if any. The Option is
not a part of the Executive’s regular or expected compensation for purposes of
calculating any severance, resignation, redundancy, end of service payments,
bonuses, long-service awards, pension or retirement benefits, or any similar
payments, which are the exclusive obligations of the Employer.

Netherlands

Waiver of Termination Rights

The Executive waives any and all rights to compensation or damages as a result
of any termination of employment for any reason whatsoever, insofar as those
rights result or may result from (a) the loss or diminution in value of such
rights or entitlements under the Plan or (b) the Executive ceasing to have
rights under, or ceasing to be entitled to any Awards under the Plan as a result
of such termination.

Dutch Subsidiary Director Notice

The Executive acknowledges and agree that the Option granted to the Executive in
connection with the Executive’s participation in the Plan are not granted as

provide as a director (“statutair bestuurder”) of a Subsidiary established under
the laws of Netherlands or operating within the Netherlands.

Portugal

applicable law.

Use of English Language

The Executive hereby expressly declares that the Executive has full knowledge of
the English language and has read, understood and fully accepted and agreed with

United Kingdom

Income Tax and Social Insurance Contribution Withholding

The following provision shall replace Article IV of the Agreement:

Regardless of any action the Company and the Employer take with respect to any
or all income tax, primary and secondary Class 1 National Insurance
contributions, payroll tax or other tax-related withholding attributable to or
payable in connection with or pursuant to the grant, vesting, or exercise of the
Option or the release or assignment of the Option for consideration, or the
receipt of any other benefit in connection with the Option (“Tax-Related
Items”), the Executive acknowledges that the ultimate liability for all Tax-
Related Items legally due by the Executive is and remains the Executive’s
responsibility and that the Company and the Employer: (i) make no
representations or undertakings regarding the treatment of any Tax-Related Items
in connection with any aspect of the Option, including the grant of the Option,
the vesting of the Option, the exercise of the Option and the sale of any Shares

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

acquired pursuant to the Option, and (ii) do not commit to structure the terms
of the Option or any aspect of the Option to reduce or eliminate the Executive’s
liability for Tax-Related Items.

As a condition to the settlement of the Option following the date of exercise,
the Company and/or the Employer shall be entitled to withhold and the Executive
agrees to pay, or make adequate arrangements satisfactory to the Company and/or
the Employer to satisfy, all obligations of the Company and/or the Employer to
account to HM Revenue & Customs (“HMRC”) for any Tax-Related Items. In this
regard, the Executive authorizes the Company or the Employer to withhold all
applicable Tax-Related Items legally payable by the Executive from any
wages/salary or other cash compensation payable to the Executive. Alternatively,
or in addition, if permissible under applicable law, the Executive authorizes
the Company, at its discretion and pursuant to such procedures as it may specify
from time to time, to satisfy the obligations with regard to all Tax-Related
Items legally payable by the Executive by one or a combination of the following:
(i) withholding otherwise deliverable whole Shares; (ii) arranging for the sale
of whole Shares otherwise deliverable to the Executive (on the Executive’s
behalf and at the Executive’s direction pursuant to this authorization); or
(iii) withholding from the proceeds of the sale of any Shares acquired upon the
exercise of the Option. If the obligation for Tax-Related Items is satisfied by
withholding a number of whole Shares as described herein, the Executive shall be
deemed to have been issued the full number of whole Shares issued upon the
exercise of the Option, notwithstanding that a number of Shares are held back
solely for the purpose of paying the Tax-Related Items due as a result of any
aspect of the Option. If, by the date on which the event giving rise to the
Tax-Related Items occurs (the “Chargeable Event”), the Executive has relocated
to a country other than the United Kingdom (the “U.K.”), the Executive
acknowledges that the Company or the Employer may be required to withhold or
account for Tax- Related Items in more than one country, including the U.K. The
Executive also agrees that the Company may determine the amount of Tax-Related
Items to be withheld and accounted for by reference to the maximum applicable
rates, without prejudice to any right which the Executive may have to recover
any overpayment from the relevant tax authorities.

The Executive shall pay to the Company or the Employer any amount of Tax-Related
Items that the Company or the Employer may be required to account to HMRC with
respect to the Chargeable Event that cannot be satisfied by the means previously
described. If payment or withholding is not made within 90 days after the end of
the
U.K. tax year in which the Chargeable Event occurs or such other period
specified in section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions)
Act 2003 (the “Due Date”), the Executive agrees that the amount of any
uncollected Tax-Related Items shall (assuming the Executive is not a director or
executive officer of the Company (within the meaning of Section 13(k) of the
U.S. Securities and Exchange Act of 1934, as amended), constitute a loan owed by
the Executive to the Company or the Employer, as effective on the Due Date. The
Executive agrees that the loan will bear interest at the then-current HMRC
Official Rate and it will be immediately due and repayable, and the Company may
recover it at any time thereafter by any of the means referred to above. If any
of the foregoing methods of collection are not allowed under applicable laws or
if the Executive fails to comply with the Executive’s obligations in connection
with the Tax-Related Items as described in this Article IV, the Company may
refuse to deliver any Shares otherwise payable upon the exercise of the Option.

Exclusion of Claim

The Executive acknowledges and agrees that the Executive will have no
entitlement to compensation or damages, insofar as such entitlement arises or
may arise from the Executive’s ceasing to have rights under or to be entitled to
exercise the Option as a result of such termination (whether the termination is
in breach of contract or otherwise), or from the loss or diminution in value of
the Option. Upon the grant of the Option, the Executive shall be deemed to have
irrevocably waived any such entitlement.

United States

Accelerated Vesting upon Retirement Eligibility

Notwithstanding anything in the Agreement or the Plan to the contrary, if the
Executive’s employment or service is terminated prior to the Option Vesting Date
due to the Executive’s retirement, the Option immediately shall fully vest,
become exercisable and will expire on the earlier of (i) six (6) years from the
Termination Date or (ii) the original expiration date of the Option. For
purposes of the foregoing, “retirement” shall mean the Executive’s termination
of service with (i) 25 years of service, (ii) 20 years of service and attainment
of age 55, or (iii) attainment of age 60.
