If you have sold or transferred all of your holding of Shares in certificated form, you should immediately send any accompanying documents (including the enclosed reply-paid envelope (for use within the UK only)) but NOT this personalised Form of Acceptance to the purchaser or transferee, or to the stockbroker, bank or other agent through whom the sale or transfer was effected, for transmission to the purchaser or transferee. If your Shares are in certificated form and you wish to sell part of your holding of Shares and also wish to accept the Offer in respect of the balance but are unable to obtain the balance certificate by 29 January 2013, you should ensure that your stockbroker or other agent through whom you make the sale obtains the appropriate endorsement or indication, signed on behalf of Capita Registrars.
