  B/C SHARE SCHEME - UPDATE IN RESPECT OF REDEMPTION OF B SHARES AND SINGLE C  
                                SHARE DIVIDEND                                 

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION IN WHOLE OR IN PART IN OR INTO THE
 UNITED STATES, CANADA, AUSTRALIA, NEW ZEALAND, JAPAN OR THE REPUBLIC OF SOUTH 
                                    AFRICA                                     

Following the announcement by J.P. Morgan Cazenove, acting as principal (and
not as agent, nominee or trustee), of the Purchase Offer earlier today, the
Company provides an update in respect of the B/C Share Scheme.

Redemption of B Shares (Immediate Capital Option)

A committee of the Board resolved on 7 July 2011 that, subject to and
conditional upon the announcement of the Purchase Offer by J.P. Morgan
Cazenove, all B Shares of 140 pence each issued pursuant to the Immediate
Capital Option (being 187,883,662 B Shares) be redeemed for 140 pence per B
Share with immediate effect. Consequently, such B Shares were redeemed earlier
today and have been cancelled. 3,366,572 B Shares issued pursuant to the
Deferred Capital Option will, however, 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 published by the Company on 13 June 2011 in relation to the B/C
Share Scheme (the "Circular").

It is expected that Shareholders entitled to receive payments in respect of the
proceeds of the redemption of B Shares issued pursuant to the Immediate Capital
Option will be sent cheques or, if Shareholders held their Existing Ordinary
Shares in CREST, will have their CREST accounts credited, by 14 July 2011.

Single C Share Dividend (Income Option)

The Single C Share Dividend of 140 pence per C Share issued pursuant to the
Income Option has today become payable and the C Shares issued pursuant to the
Income Option have today been automatically reclassified as Deferred Shares
having negligible value and carrying extremely limited rights.

It is expected that Shareholders entitled to receive the Single C Share
Dividend will be sent cheques or, if mandate instructions are held in respect
of a Sterling bank account, that payments will be made by BACS to mandated
accounts in respect of the Single C Share Dividend by 14 July 2011.

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