Following the purchase by J.P. Morgan Cazenove, acting as principal (and not as

to the Purchase Offer (as announced earlier today by the Company), such C
Shares have today subsequently been purchased by the Company from J.P. Morgan
Cazenove pursuant to the Option Agreement. The price paid by the Company to
J.P. Morgan Cazenove for such purchase was a price per C Share of an amount
equal to the aggregate of (i) 140 pence plus (ii) an amount equal to any stamp
duty or stamp duty reserve tax paid by J.P. Morgan Cazenove as a result of its
purchase of the C Shares pursuant to the Purchase Offer divided by the total
number of C Shares so purchased, being an aggregate amount of £69,978,771.50.
The purchased C Shares will be cancelled by the Company.

J.P. Morgan Cazenove has today also purchased, for an aggregate consideration
of one penny, the Deferred Shares arising on the automatic reclassification of
the 233,924,818 C Shares in respect of which the Single C Share Dividend became
payable. Pursuant to the terms of the Option Agreement as described in the
circular published by the Company on 13 June 2011 in relation to the B/C Share
Scheme (the "Circular"), the Company has today purchased such Deferred Shares
from J.P. Morgan Cazenove for an aggregate consideration of one penny. Those
purchased Deferred Shares will be cancelled by the Company.

3,366,572 B Shares, issued pursuant to the Deferred Capital Option, will
continue to be in issue until such time as they may be redeemed in accordance
with the terms and conditions set out in the Circular.

Unless the context otherwise requires, capitalised terms used in this
announcement shall have the same meaning ascribed to them in the Circular.
