You can choose to receive all regular communications from the Company electronically. Would you prefer to receive an email or download what you wanted rather than receive Annual Reports, Notices of Meeting, dividend tax vouchers?

Advantages of electronic communication are:

• Security: your documents cannot be lost in the post or read by others;
• Easy access: check your shareholding and account transactions on-line at any time;
• Convenience: change your name, address or dividend mandate details on-line;
• Environmentally friendly: the environmental impact of producing and circulating printed documents, and of your disposing of them, is reduced.
