UPDATE TO TIMETABLE

The Company wishes to advise Shareholders that, given that Qualifying Shareholders holding fewer than 2,098,420 Ordinary Shares will not have sufficient shares entitling them to subscribe for Bonds in the Open Offer, the London Stock Exchange will not be marking the Company's Shares as ex-entitlement.

Accordingly, the relevant date for all entitlements under the Open Offer will be the Record Date for the Open Offer, being 5.00 p.m. on 23 January 2013.

All capitalised terms used in this announcement are as set out in the circular posted to Shareholders today.
