To register for the Signal Shares you will need your investor code, which can be located on your share certificate/dividend tax voucher. Once registered you will immediately be able to vote.

Lines are open between 9.00am and 5.30pm Monday to Friday, excluding public holidays in England and Wales.

We would like to take this opportunity to thank you for having consented to receive these documents via the Company's website rather than in hard copy form, as this will contribute to cost savings for the Company and will minimise unnecessary paper usage.

Yours faithfully

S Ahmed Company Secretary
