The C Shares were issued by way of an offer for subscription launched in October

those attributed to the Ordinary Shares. The 17,719,270 C Shares have converted

Company's articles of association.

Accordingly, the directors announce the issue of 21,959,891 new Ordinary Shares
and 66,635,489 Deferred Shares, which Deferred Shares have been purchased by the
Company in accordance with the Company's articles of association for an
aggregate consideration of 67p and cancelled.

Application will be made for the new Ordinary Shares to be admitted to the
Official List and to trading on the London Stock Exchange's market for listed
securities. An application will also be made for a cancellation of the admission
of the C Shares to the Official List and of the trading of the C Shares on the
London Stock Exchange's market for listed securities.
