| | An Award may be subject, in whole or in part, to a performance target selected by the Company which will normally have to be met before the Award (or that part of it subject to the performance target) can Vest. The Vesting of an Award can be subject to any additional terms
 and conditions the Company considers appropriate. If the Vesting of an Award is subject to any performance target or any additional terms and conditions, these will be specified at the Date of Grant. If Awards are exchanged under Rule 5.9, the performance target can be varied
 at the discretion of the Remuneration Committee to take account of this.

 arrangement is sanctioned by the court. Subject to this, the Remuneration Committee may decide to take other factors into account, which it believes to be relevant in permitting the Award to Vest beyond the extent to which the performance target has been met.

| | If the performance target is not met at the end of the Restricted Period, extended under this Rule 7.3, that part of the Award to which the performance target applies will lapse and the Participants will not be entitled to any Shares the subject of that part of the Award. Participants
 will be notified in writing of any of these decisions.

| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | When an Award has Vested, the Participant will be entitled to Shares the subject of that Award. The number of Shares he is entitled to (which will be transferred to the Participant as soon as reasonably practicable) will depend on the extent to which any applicable performance
 target has been met and will be subject to any withholdings in accordance with Rule 8.2 that may be necessary on account of a Participants Tax Liability in respect of the Award.
