shares that were successfully tendered), the adjusted post-Tender NAV as at
close of business on Thursday 11 September 2008 (the Calculation Date) for
continuing shareholders was 137.56p per share. This is based upon the
82,351,197 shares that will remain in issue following the implementation of the
