Performance Share Plan

Under the rules of the performance share plan ('the plan'), awards are subject to uplift for notional dividends made or paid during the performance period.

Newly issued or treasury shares cannot be used to satisfy awards under this plan. Participants cannot be directors of the company at the time of grant. The awards will normally become capable of exercise after the end of the vesting period and must be exercised within 90 days thereafter.
