Performance Share Plan

Under the rules of the performance share plan, awards are subject to uplift for
notional dividends made or paid during the performance period. Accordingly, the
dividend shares shown below have been notionally added to and form part of the
award. In respect of the final dividend of 22.03 pence per share paid on 3
August 2009, the number of additional shares granted has been calculated using
the closing share price on 3 August 2009 of 453 pence per share. The figures
reflect the maximum number of shares over which the option might be exercised.
The actual number will depend upon the extent to which the established
performance conditions are satisfied over the performance period. The awards
are issued for nil consideration and may be exercised at nil cost to the
participant.

Retention Awards

As part of the terms of Philip Green's recruitment, the company established a
matched share incentive scheme for him as sole participant by which the company
undertook to match (on 16 January 2007) an investment of 100,000 shares made by
Mr Green himself upon his appointment provided he remains with the group until
12 February 2011. The award is subject to a dividend enhancement mechanism by
which further shares are notionally added to the award on each intervening
dividend payment date.

As part of the terms of Tim Weller's recruitment, the company established a
matched share incentive scheme for him as sole participant by which the company
undertook to match an investment of 39,000 shares made by Mr Weller himself
upon his appointment (on 1 July 2006) provided he remains with the group up to
and beyond the implementation of the next regulatory reviews. The award is
subject to a dividend enhancement mechanism by which further shares are
notionally added to the award on each intervening dividend payment date.

In order to facilitate the retention of Charlie Cornish up to and beyond the
next regulatory reviews the company established a special long-term incentive
scheme for him as sole participant. Under the scheme an award equal to his
annual salary was granted to him in the form of an option over 47,027 shares on
16 March 2007. The award is subject to performance conditions and is also
subject to a dividend enhancement mechanism by which further shares are
notionally added to the award on each intervening dividend payment date.

The dividend shares shown below have been notionally added to and form part of
the awards. In respect of the final dividend of 22.03 pence per share paid on 3
August 2009, the number of additional shares granted has been calculated using
the closing share price on 3 August 2009 of 453 pence per share.

Deferred Share Award Plan

Under the rules of the deferred share award scheme (`the scheme') awards are
subject to uplift for notional dividends made or paid during the vesting
period. Accordingly the dividend shares shown below have been notionally added
to and form part of the award. In respect of the final dividend of 22.03 pence
per share paid on 3 August 2009, the number of additional shares awarded has
been calculated using the closing share price on 3 August 2009 of 453 pence per
share. 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. Newly issued or treasury
shares cannot be used to satisfy awards under this plan.  No directors of the
company can participate in the scheme. 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.
