|14.1   |  | The exercise or vesting of any Award or Option may by its terms be conditional upon, and/or the number of Shares which may be acquired on exercise of an Award or Option or transferred on the vesting of an Award may be determined by, the attainment of
one or more objective performance targets ("Performance Target"). The terms of each Performance Target shall themselves be determined by the Trustees in their discretion having considered the recommendations of the Remuneration Committee of the Board
and shall be specified to the relevant Eligible Person when he or she is notified of the grant of the Award or Option. The Trustees may specify that the Performance Target shall be disapplied, altered or deemed to be satisfied if Rules 11.2 or
14 apply.                                                                                                                                             
|14.2   |  | Where an issue or reorganisation by the Company or any member of the Group (including, without limitation, any issue of shares or securities or any reduction of capital or sub-division or consolidation of shares) or any other event or circumstance
(including a change in accounting policies or practice or a change in the length of the Company's accounting period) causes the Trustees (having consulted the Remuneration Committee of the Board) reasonably to consider that a different performance
target would be a more appropriate measure of performance and that the different Performance Target will be a fairer measure of such performance or that any amended performance target will provide a more effective incentive to the holders of Options,
the Trustees may determine that a new Performance Target shall be substituted for the existing Performance Target applicable to such Award or Option.
|14.3   |  | Where the Trustees have imposed a Performance Target under Rule 10.1 upon the grant of an Award or Option, that Award or Option may not be exercised or vest except in accordance with or to the extent permitted by any such Performance Target, as
from time to time varied in accordance with Rule 10.2.

|18.1   |  | Notwithstanding Rule 11 above, it shall be a term and condition of any Option or any Award which requires to be exercised that in the event of notice being given to shareholders of a resolution for the winding-up of the Company, the Option or
Award shall be capable of exercise within the period of six months commencing on the date of such notice and the Option or Award shall lapse at the end of such period or on the winding up of the Company, if earlier. Notwithstanding Rule 11 above,
 it shall be a term and condition of any Award which does not require to be exercised that in the event of the winding-up of the Company before the Award has vested, the unvested portion of the Award shall lapse upon the winding up of the
Company.                                                                                                                                                                                            
|18.2   |  | If the Company is succeeded by a successor corporation, or if any person ("the Offeror") obtains Control of the Company, then the Trustees may substitute equivalent awards or options or provide substantially similar consideration to grantees as was
provided to shareholders (after taking into account the existing provisions of the Awards or Options). If the Trustees do not substitute awards or options, such Awards or Options shall accelerate and become exercisable or vest in full on such
conditions and during such period or at such time as the Trustees shall determine prior to such succession or change of control. Any Awards which require to be exercised and any Options not so replaced or exercised during such period shall lapse and
cease to be exercisable at the end of such period. Any Awards which do not require to be exercised which are not so replaced or vested at such time shall lapse immediately thereafter.
