Participating Company.
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(2) |  | For the purposes of Rule 2(1) above:-

|(3) |  | A person is not eligible to be granted an option at any time:-

employment; or
| | --- |  | ------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | when he is not eligible to participate in this Plan by virtue
of paragraph 8 of Schedule 9 (material interest in close company).                

3.      GRANT OF OPTIONS



|(1) |  | Subject to Rule 4 below, the Committee or the Trustees may by deed (but,
in the case of the Trustees, only following a recommendation of the
Committee) grant an Option to acquire shares in the Company which satisfy
the requirements of paragraphs 10 to 14 of Schedule 9 (fully paid up,
unrestricted, ordinary share capital) on the Grant Date and (subject to
Rule 7(5)) at the date of exercise of the Option, upon the terms set out
in this Plan and upon such other objective terms as the person granting
the Option may specify, to any person who is eligible to be granted an
Option in accordance with Rule 2 above.

|   
|(2) |  | If, after the Committee or the Trustees (as the case may be) have imposed
a condition pursuant to Rule 3(1) (performance condition), events happen
which cause them to consider that it is no longer appropriate they may
vary such condition provided always that any such amendment may only be
one which the Committee reasonably considers will result in a fairer
measure of the performance, will ensure that this Plan operates more
effectively in the achievement of its purpose of providing share benefits
for employees who contribute to the prosperity of the Company and its
shareholders, and will be neither substantially more nor less difficult to
satisfy than the original condition was intended to be at the time of its
grant.
|   
|(3) |  | The price at which shares may be acquired by the exercise of an Option
shall be determined by the Committee before its grant, but shall not be
less than:

| | (b) |  | at any other time when the circumstances are considered by the
Committee to be sufficiently exceptional to justify its grant; and

associated company of the Company, to exceed or further exceed £30,000 (or

to which an option was granted shall be calculated:-

|(6) |  | References in this Rule 4 to shares being issued pursuant to the exercise
of options shall include any shares issued for the purpose of satisfying
any such option.

|   
|(3) |  | Subject to Rule 3(2), Rule 5(4) and paragraphs (a) and (c) of Rule 5(5)
and to Rule 6(6) below, an Option may not be exercised if the relevant

the relevant conditionis a condition related to performance which is
specified by the Committee under Rule 3(1) above.        
|   
|(4) |  | If any Participant dies, any Option granted to him may (and must, if at
all) be exercised by his personal representatives within 12 months after

either he is a director or employee of a Group Member or he is or would be
entitled to exercise the option by virtue of Rule 5(5).

|(5) |  | If any Participant ceases to be a director or employee of a Group Member
(otherwise than by reason of his death), the following provisions apply in
relation to any Option granted to him:-                                                                                                                                                             



| | (a) |  | if he so ceases by reason of injury, disability, pregnancy or
redundancy (within the meaning of the Employment Rights Act 1996), or
by reason only that his office or employment is in a company which
ceases to be a Group Member, or relates to a business or part of a
business which is transferred to a person who is not a Group Member,
the Option may (and subject to Rule 5(4) must, if at all) be
exercised within the exercise period;
| | --- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | if he so ceases by reason of retirement on reaching the age at
which he is bound to retire in accordance with the terms of his

exercise period;                                                                                                                                                                   
|
| | (c) |  | if he so ceases for any other reason, the Option may not be
exercised at all unless the Committee shall so permit, in which event
it may (and subject to Rule 5(4) must, if at all) be exercised to the
extent permitted by the Committee within the exercise period;

12 months in the cases where sub-rules (a) or (c) apply or six months in
cases where sub-rule (b) applies after his so ceasing, or such later date
as the Committee may determine, but such date shall not be later than 42
months after the later of the Grant Date and the last time when the
Participant exercised an Option with income tax relief.

ceasing to be a director or employee of a Group Member until such time as
he is no longer a director or employee of any Group Member.

| | (a) |  | the Committee considers that the issue or transfer of the
shares subject to the Option would be lawful in all relevant
jurisdictions; and                                                                                                                                                                                                                                                                                                                                                                  
| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | in a case where a company which is or was a Group Member or the
Trustees are obliged to (or would suffer a disadvantage if it were
not to) account for any tax (in any jurisdiction) for which the
person in question is liable by virtue of the exercise of the Option
and/or for any social security contributions for which the person in
question is liable (including but not limited to, primary National
Insurance contributions in the UK) (together, the Tax Liability),
that person has either:



| | (i)  |  | made a payment to the Group Member (or former Group
Member) or the Trustees of an amount equal to the Tax Liability; or                                                                                                                                                                               
| | ---- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (ii) |  | entered into arrangements acceptable to that person
or another Group Member to secure that such a payment is made
(whether by authorising the sale of some or all of the shares
on his behalf and the payment to the relevant person of the
relevant amount out of the proceeds of sale or otherwise).



|(10) |  | Within 30 days after an Option has been exercised by any person, the
grantor of the Option shall procure the allotment or transfer to him (or a
nominee for him) of the number of shares in respect of which the Option
has been exercised.
|---- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|    
|(11) |  | All shares allotted under this Plan shall rank equally in all respects
with shares of the same class then in issue except for any rights
attaching to those shares by reference to a record date prior to the date
of allotment.           

6.      TAKEOVER, RECONSTRUCTION AND WINDING-UP



|(1) |  | Subject to Rule 6(9), if any person obtains control of the Company
(within the meaning of section 840 of the Taxes Act 1988) as a result of
making a general offer to acquire shares in the Company, or having
obtained control makes such an offer, the Committee shall within 7 days of
becoming aware thereof notify every Participant thereof and, subject to
earlier lapse under Rules 5(4), 5(5) and 5(7), any Option may be exercised
within one month (or such longer period up to a maximum of six months as
the Committee may permit) of the notification, but to the extent that it
is not exercised within that period shall lapse on the expiry of that
period.
|--- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(2) |  | For the purposes of Rule 6(1), a person shall be deemed to have obtained
control of the Company if he and others acting in concert with him have
together obtained control of it.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
|   
|(3) |  | Subject to Rule 6(9), if any person becomes bound or entitled to acquire
shares in the Company under sections 428 to 430F of the Companies Act
1985, or if the Company passes a resolution for voluntary winding up, or
if an order is made for the compulsory winding up of the Company, the
Committee shall forthwith notify every Participant thereof and, subject to
earlier lapse under Rules 5(4), 5(5) and 5(7), any Option may be exercised
within one month of

|    |  | such notification, but to the extent that it is not exercised within that
period shall lapse on the expiration of that period.

|   
|(4) |  | Subject to Rule 6(9), if a scheme of arrangement or compromise under
section 425 of the Companies Act 1985 is proposed, the Committee shall
forthwith notify every Participant that, subject to earlier lapse under
Rules 5(4), 5(5) and 5(7), any Option may be conditionally exercised
within the period commencing from the date of notification and ending on
the day immediately preceding the date scheduled for the Court hearing or
such later date up to a maximum of six months from the date scheduled for
the Court hearing, as the Committee may determine. If the Court sanctions
the scheme of arrangement or compromise:



| | (a) |  | any Option so conditionally exercised shall immediately
become unconditionally exercised by the Participant; and
| | --- |  | ----------------------------------------------------------------------------------------------------------------
|
| | (b) |  | any Option not so conditionally exercised shall lapse on the
expiration of that period.                         



| |  | However, if the Court declines to sanction the scheme of arrangement or
compromise, the conditional exercise shall not be effective and the
Options shall continue to subsist.
| |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(5) |  | If a demerger, special dividend or other event which, in the opinion of
the Committee would affect the share price to a material extent, is
proposed then the Committee acting fairly and reasonably may at its
discretion forthwith notify every Participant that, subject to earlier
lapse under Rule 5 or the other provisions of this Rule 6, an Option may
be exercised on such terms and during such period preceding or following
such event as may be determined by the Committee provided that if an
Option is exercised in advance of and conditional upon such event and such
event shall not occur then the conditional exercise shall not be effective
and the Option shall continue to subsist.

|   
|(6) |  | In relation to an Option which would, but for Rule 5(3) (Performance
Condition) above, be exercisable by virtue of an event mentioned in Rule
6(1), 6(3), 6(4) or 6(5), the Committee shall acting fairly and reasonably
determine the extent (if any) to which the performance condition has been
satisfied at the date on which such event occurs (as if that date were the
end of the relevant performance period) and the Option shall become
exercisable to that extent.

| |  | company, release any Option which has not lapsed (the old option) in
consideration of the grant to him of an option (the new option) which
(for the purposes of that paragraph) is equivalent to the old option but
relates to shares in a different company (whether the acquiring company
itself or some other company falling within paragraph 10(b) or (c) of
Schedule 9).
| |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(8) |  | The new option shall not be regarded for the purposes of Rule 6(7) as
equivalent to the old option unless the conditions set out in paragraph
15(3) of Schedule 9 are satisfied, but so that the provisions of this Plan
shall for this purpose be construed as if:-
|--- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (a) |  | the new option were an option granted under this Plan at the
same time as the old option;

|
| | (b) |  | except for the purposes of the definitions of Group Member,
Participating Company and Subsidiary in Rule 1(1) and the
reference to the Committee in Rule 5(7), the expression the
Company were defined as a company whose shares may be acquired by
the exercise of options granted under this Plan; and

| | (c) |  | Rule 8(2) below were omitted.                                                                                                                                                                                                                                                                                       



|(9) |  | If:-
|--- |  | ----



| | (a) |  | the events referred to in this Rule 6 are part of an
arrangement which will mean that the Company will be under the
control of another company (within the meaning of Section 840 of the
Taxes Act 1988) or the business of the Company is carried on by
another company, and the persons who owned the shares in the Company
immediately before the change of control will immediately afterwards
own more than 50% of the shares in that other company (a
Reorganisation); and
| | --- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Reorganisation and, subject to earlier lapse under Rules 5(4), 5(5) and
5(7), shall lapse three months following the notification of the
Reorganisation to every Participant. Notwithstanding that an Option does
not become exercisable, nothing in this Rule 6(9) shall prevent the
provisions of Rule 6(7) from applying. Where Rule 6(7) is applied in
these circumstances, the provisions of Rule 6(8) will also apply but with
the omission of paragraph (c) of Rule 6(8).

7.      VARIATION OF CAPITAL



|(1) |  | Subject to Rule 7(3), in the event of any variation of the share capital
of the Company, the Committee may make such adjustments as it considers
appropriate under Rule 7(2).
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(2) |  | An adjustment made under this sub-rule shall be to one or more of the
following:-                                                                                            



| | (a) |  | the number of shares in respect of which any option may be
exercised;                                                                                                                                                  
| | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | the price at which shares may be acquired by the exercise of
any option;                                                                                                                                               
|
| | (c) |  | where any option has been exercised but no shares have been
allotted or transferred pursuant to the exercise, the number of
shares which may be so allotted or transferred and the price at which
they may be acquired.



|(3) |  | At a time when this Plan is approved by the Inland Revenue under Schedule
9, no adjustment under Rule 7(2) shall be made without the prior approval
of the Inland Revenue.
|--- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### 





|(4) |  | An adjustment under Rule 7(2) may have the effect of reducing the price
at which shares may be acquired by the exercise of an Option to less than
their nominal value, but only if and to the extent that the Committee
shall be authorised to and shall determine that it shall capitalise from
the reserves of the Company a sum equal to the amount by which the nominal
value of the shares in respect of which the Option is exercised and which
are to be allotted pursuant to the exercise exceeds the price at which the
shares may be subscribed for and to apply that sum in paying up that
amount on the shares; and so that on the exercise of any Option in respect
of which such a reduction shall have been made the Committee shall
capitalise that sum (if any) and apply it in paying up that amount.
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(5) |  | If the shares subject to any Option cease to satisfy the requirements of

Rule 5(10) of Part A, the Committee (but only with the prior consent of
the board of directors of the Company) may determine that, in substitution
for his right to acquire such number of those shares as the Committee may
decide (but in full and final satisfaction of his said right), he shall be
paid by way of additional emoluments a sum equal to the cash equivalent of
that number of shares.

|   
|(2) |  | For the purposes of this Rule, the cash equivalentof any shares is the
amount by which the Committees opinion of the market value of those
shares on the day last preceding the date on which the Option was

shares were listed in the Official List of the UKLA, the middle-market
quotation of shares of that class, as derived from the Daily Official List
of the London Stock Exchange, on the dealing day last preceding that date)

7.      TAKEOVER, RECONSTRUCTION AND WINDING-UP



|(1) |  | Rule 6(6) of Part A shall be subject to the proviso that the Committee
may (in exceptional circumstances) determine that the Option should become

Company over the relevant period.

in the relevant acquiring company, provided that the new options meet
the conditions of paragraphs 15(3)(b) to (d) of Schedule 9. Rule 6(8)
shall be construed accordingly.

material impact on the value of a share in the Company.

options granted to such participants are not overall more favourable than
the terms of options granted to other participants.

| | Options granted under Part C may be designated as incentive stock
options (ISOs) within the meaning of section 422 of the United States

addition to the limitations otherwise imposed by the Plan, be limited to
those persons who are employees of the Company or its parent or
subsidiary corporations within the meaning of section 424(e) and (f),
respectively, of the US Tax Code.

4.      GRANT OF OPTIONS



| |

under Part C.                                                                                                                                                                                                                                                                                                                                                                             
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(2) |  | The exercise price of any Option granted as an ISO shall not be less than
the fair market value of the shares at the time such Option is granted
(determined in accordance with Section 422(c)(1) of the U.S. Tax Code and
any regulations promulgated thereunder).                                                                                                                                                                                            
|   
|(3) |  | The aggregate number of shares for which ISOs may be granted under Part C
to all option holders during the term of the Plan shall not exceed
200,000,000 (being 10% of the expected issued share capital on the
adoption of the Plan), subject to adjustment if any of the events
envisaged in Rule 7 of Part A occur.                                                                                                                                         
|   
|(4) |  | To the extent that the aggregate fair market value of shares with respect
to which ISOs are exercisable for the first time by an option holder
during any calendar year (under all plans or schemes of the Company or its
parent or subsidiary corporations within the meaning of sections
424(e) and (f), respectively, of the US Tax Code) exceeds US$100,000, such
Options shall be treated, to the extent of the excess, as nonqualified
stock options.

6.      EXERCISE OF OPTIONS



|(1) |  | If any Option is exercised in accordance with Rule 5 of the Plan more
than three (3) months after the date that the option holder was last
employed by the Company (or by its parent or a subsidiary as defined in
this Part C), or in the case of total disability (as defined by section
422(c)(6) of the US Tax Code) more than twelve (12) months after the date
that the option

|    |  | holder was last employed by the Company (or by its parent or a subsidiary
as defined in this Part C), then such option shall be treated as a
nonqualified stock option for purposes of the US Tax Code.
|--- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(2) |  | The Grantor may satisfy its obligations under this Part C of the Plan by
delivering American Depository Shares representing Shares in the Company.                                                     

7.      CASH EQUIVALENT



|(1) |  | Where an Option granted under Part C to which this Rule applies has been
exercised by any person in respect of any number of shares, and those
shares have not yet been issued or transferred to him in accordance with
Rule 5(10) of Part A, the Committee (but only with the prior consent of
the board of directors of the Company) may determine that, in substitution
for his right to acquire such number of those shares as the Committee may
decide (but in full and final satisfaction of his said right), he shall be
paid by way of additional emoluments a sum equal to the cash equivalent of
that number of shares.
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(2) |  | For the purposes of this Rule, the cash equivalent of any shares is the
amount by which the Committees opinion of the market value of those
shares on the day last preceding the date on which the Option was
exercised (or, if at the relevant time shares of the same class as those
shares were listed in the Official List of the UKLA, the middle-market
quotation of shares of that class, as derived from the Daily Official List
of the London Stock Exchange, on the dealing day last preceding that date)
exceeds the price at which those shares may be acquired by the exercise of
the Option.                      
|   
|(3) |  | As soon as reasonably practicable after a determination has been made
under Rule 7(1) of this Part C that a person shall be paid a sum in
substitution for his right to acquire any number of shares:                                                                                                                                                                                                                                                                                                                                                                                                                            



| | (a) |  | the Company shall pay to him or procure the payment to him of
that sum in cash; and                            
| | --- |  | ---------------------------------------------------------------------------------------------------------------
|
| | (b) |  | if he has already paid the Company for those shares, the
Company shall return to him the amount so paid by him.



|(4) |  | There shall be made from any payment under this Rule such deductions (on
account of tax or similar liabilities) as may be required by law or as the
Committee may reasonably consider to be necessary or desirable.

|(1) |  | Rule 6(6) of Part A shall be subject to the proviso that the Committee
may (in exceptional circumstances) determine that the Option should become
exercisable on a different basis if they consider that such a curtailment
of the performance period does not properly reflect the performance of the
Company over the relevant period.

Securities Act), the Securities Exchange Act of 1934, as amended,
applicable State securities laws, and the requirements of any stock
exchange upon which shares or American Depository Shares may then be

|(3) |  | Subject to Rules 2(4), 2(9) and Rule 3, the Board shall recommend to the
Trustee that it grants to the Eligible Executive a Matching Award over
such number of Shares (or one half thereof in the case of an Eligible
Executive who, at the time a Bonus is due to be paid, is within two years
of his Normal Retirement Date) as does not exceed the number found by
dividing the amount of the Bonus invested in Shares (before any deductions
required by law) by the market value of a Share, such value to be
reasonably determined by the Trustee, on a dealing day (or the average of
three dealing days) within the period of 7 days prior to the Date of Grant
relating to the Matching Award (rounded down to the nearest whole number
of Shares), upon the terms set out in this Plan and upon such other
objective terms (performance conditions) as the Trustee may specify.
|   
|(4) |  | A Matching Award may only be granted within the period of six weeks
beginning with the Approval Date or within the period of six weeks after
any Announcement Date or any other

Participant of a written notice stating the number of shares subject to
the Matching Award, the Date of Grant, the number of Qualifying Shares
acquired by him, the Retention Period and, if applicable, the performance
condition applying to them.

|   
|(3) |  | Notwithstanding any other Rule of this Plan, the exercise or release of
Matching Awards will be subject to such additional conditions and
procedures as the Trustee and/or Board may determine are necessary or
desirable for the time being in order to comply with or take into account
any legal or taxation obligations of, or implications for, a Group Member
in respect of such exercise or release. For the avoidance of doubt, and
without limiting any of the foregoing, the Trustee and/or Board may
require that in a case where a Group Member is obliged to account for or
could suffer a disadvantage should it not account for any tax (in any
jurisdiction) for which the person in question is liable by virtue of the
exercise or release of the Matching Award and/or for any social security
contributions recoverable from the person in question (together, the Tax
Liability) that person has either:



| | (a) |  | made a payment to the relevant Group Member or Trustee of an
amount equal to the Tax Liability; or                                                                  
| | --- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | entered into arrangements with the relevant Group Member, the
Trustee or another company to secure that such a payment is made
(whether by authorising any person to

| |  |  | procure the sale on his behalf of some or all of the shares subject
to the Matching Award and authorising the payment to the relevant
Group Member or Trustee of the appropriate amount out of the
proceeds of sale, or otherwise).
| |  |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(4) |  | The Trustee shall (subject to any necessary consent) transfer the Shares
in respect of which a Matching Award within 30 days after such exercise or
release.                                                                                                                 
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(5) |  | Where Shares are issued to or transferred to a participant following the
exercise of an option, the participant shall not be entitled to any
rights, attaching to such shares by reference to a record date before the
date on which the shares are so issued or transferred.

5.      TAKEOVER, RECONSTRUCTION AND WINDING-UP



|(1) |  | Subject to Rule 5(8), if any person obtains Control of the Company as a
result of making a general offer to acquire shares in the Company, or
having obtained Control makes such an offer, the Board shall within 7 days
of becoming aware thereof notify every Participant thereof and, subject to
earlier lapse under Rule 4, any Matching Award may be exercised or
released within one month (or such longer period as the Board may permit)
of the notification, but to the extent that it is not exercised or
released within that period shall lapse on the expiry of that period.

|

shares in the Company under sections 428 to 430F of the Companies Act
1985, or if the Company passes a resolution for voluntary winding up, or
if an order is made for the compulsory winding up of the Company, the
Board shall forthwith notify every Participant thereof and, subject to
earlier lapse under Rule 4, any Matching Award may be exercised or
released within one month of such notification, but to the extent that it
is not exercised or released within that period shall lapse on the
expiration of that period.

Rule 4, any Matching Award may be conditionally exercised or released
within the period commencing from the date of notification and ending on
the day immediately preceding the date scheduled for the Court hearing or
such other date as the Board may determine. If the Court sanctions the
scheme of arrangement or compromise, any Matching Award not so
conditionally exercised or released shall lapse on the expiration of that
period. However, if the Court declines to sanction the scheme of
arrangement or compromise, the conditional exercise or release shall not
be effective and the Matching Award shall continue to subsist.

|(5) |  | If a demerger, special dividend or other event which, in the opinion of
the Board would affect the share price to a material extent, is proposed
then the Board may at its discretion forthwith notify every Participant
that, subject to earlier lapse under Rule 4 or this Rule 5, a Matching
Award may be conditionally exercised or released during such period
preceding such event as may be determined by the Board provided that if
such event shall not occur then the conditional exercise or release shall
not be effective and the Matching Award shall continue to subsist.

exercisable or releasable by virtue of an event mentioned in Rule 5(1),
5(3) or 5(4), the Board shall determine the extent

demerger involving the Company or any Subsidiary, or the payment of a
capital or other dividend or distribution which is of an unusual nature
and which, in the opinion of the Board, has a material impact on the value
of a Share, the Board (with the consent of the Trustee) may make such
adjustment to the number of Shares subject to a Matching Award as it
considers appropriate.

Plan.

##### 





|(2) |  | Subject to Rule 7(3), no alteration to the advantage of the persons to
whom Matching Awards have been or may be granted shall be made under the
definition of Eligible Executive and Rules 2, 3, 4(1) to 4(3) and 6
without the prior approval by ordinary resolution of the members of the
Company in general meeting.
|--- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|   
|(3) |  | Rule 7(2) shall not apply to any minor alteration to benefit the
administration of this Plan, to take account of a change in legislation or
to obtain or maintain favourable tax, exchange control or regulatory
treatment for Participants or any Group Member.

| | (a) |  | the Board shall have invited every relevant Participant to give
an indication as to whether or not he approves the alteration; and

| | (b) |  | the alteration is approved by a majority of those Participants
who have given such an indication.                                 



|(5) |  | Notwithstanding any other provision of this Plan, the Board may in
respect of Participants who are or who may become subject to taxation
outside the United Kingdom on their remuneration amend or add to the
provisions of the Plan as it considers necessary or desirable to take
account of or to mitigate or to comply with the relevant overseas
taxation, securities or exchange control laws provided that the terms of
matching awards granted to such participants are not overall more
favourable than the terms of matching awards granted to other participant.

|(6) |  | If, after the Trustee has imposed a condition pursuant to Rule 2(3)
(performance condition), events happen which cause them to consider that
it is no longer appropriate they may vary such condition provided always
that any such amendment may only be one which the Board reasonably
considers will result in a fairer measure of the performance, will ensure
that this Plan operates more effectively in the achievement of its purpose
of providing share benefits for employees who contribute to the prosperity
of the Company and its shareholders, and will be neither substantially
more nor less difficult to satisfy than the original condition was
intended to be at the time of its grant.
