                           DEFERRED SHARE AWARD PLAN                           

                                 30 JUNE 2010                                  

Deferred Share Award Plan

The following awards vested on 11 June 2010 pursuant to the rules of the
deferred share award scheme (`the scheme') as approved by the board on 25
November 2008. Under the terms of the scheme, awards will (which are structured
as options to acquire shares in the company with a zero exercise price) be
satisfied by using shares purchased in the market or by payment of a cash
amount equal to the market value on the date of exercise of the shares
(including dividend equivalent shares) held. The mid market price on 11 June
2010 was 560p per share. Newly issued or treasury shares cannot be used to
satisfy awards under this plan. The awards will normally become capable of
exercise after the end of the vesting period and must be exercised within 90
days thereafter. The ability to exercise an award is not subject to satisfying
a performance target.
