It is intended that the first 25 million Ordinary Shares purchased under the Programme will be held in Treasury for issue in due course to the Company's Employee Benefit Trust.

The total voting rights in the Company will accordingly be 1,910,467,201. This figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the Disclosure and Transparency Rules.
