Dear Sir/Madam

Companies Act 1985

Disclosures of Interests in Voting Shares - Changes in Registered Holders

In compliance with Part IV of the above Act, as amended, I inform you that
following a change in Trustee and Custodian, the registration details for some
funds currently managed by Prudential plc and Group Companies have changed from
that previously notified to you.  As a direct result, the names of the
registered holders which comprise our notifiable interest in the voting shares
in your company will now be as listed on the attached report.

Please note that the following changes have taken effect:

CLYDESDALE BK NOMS LTD MGC

Has been changed to:

NORTRUST NOMINEES LIMITED A/C MKM01

It must be stressed that is not a change to our notifiable interest in the
voting shares of your company that has generated this notification, but merely a
change in registration details.

Yours faithfully

Richard Harding
For and on behalf of Prudential plc
