Notes relating to the Proxy Form

• 1. Every holder has the right to appoint some other person(s) of their choice as his or her proxy to exercise all or any of his or her rights, to attend, speak and vote on their behalf at the Meeting. A proxy need not be a member of the Company.
• 1. If you wish to appoint a proxy other than the Chairman of the Meeting, please delete the words 'the Chairman of the Meeting or' and substitute the name of your choice. If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holder's name the number of Shares in relation to which they are authorised to act as your proxy. If left blank your proxy will be deemed to be authorised in respect of your full voting entitlement (or in the case of a corporate shareholder, the full voting entitlement for each relevant designated account).
• 1. A member may appoint a proxy or proxies by (i) completing this proxy form, together with the power of attorney (if any) under which it is signed, or a notarially certified copy thereof, and sending it to the Company's registrar, Capita Asset Services, PXS 1, 34 Beckenham Road, Beckenham BR3 4ZF so as to arrive not later than 10.30am on Wednesday 3 May 2017. Note that you may return the proxy form in an envelope to FREEPOST CAPITA PXS (this is the only address information required and no stamp is needed); or (ii) if you are a user of the CREST system (including CREST Personal Members), having an appropriate CREST message transmitted (please see note 5 below). To appoint more than one proxy, an additional proxy form may be obtained by contacting Capita Asset Services on 0871 664 0300 (calls cost 12p per minute plus your phone company's access charge. Lines are open 9.00am – 5.30pm, Monday to Friday) or from outside the UK +44 (0)371 664 0300 (calls outside the UK will be charged at the applicable international rate), or you may copy this form. Please indicate in the box next to the proxy holder's name the number of Shares in relation to which they are authorised to act as your proxy. Please also indicate by ticking the box provided if the proxy instruction is one of multiple instructions being given. All forms must be signed and should be returned together in the same envelope.
• 1. You may instruct your proxy how to vote by marking the appropriate box next to each resolution. The resolutions are contained in the Notice of Meeting and further details are contained in the Explanatory notes in the Notice of Meeting. If in respect of any resolution you have not given specific instructions on how your proxy should vote, your proxy will have discretion to vote on that resolution in respect of the voting entitlement you granted to that proxy, as they see fit. Your proxy will also have discretion to vote as they see fit on any other business which may properly come before the Meeting, including amendments to resolutions, and at any adjournment of the Meeting. A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution.
• 1. To appoint a proxy or to give or amend an instruction to a previously appointed proxy via the CREST system, the CREST message must be received by the issuer's agent (ID number RA10) by 10.30am on Wednesday 3 May 2017. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the issuer's agent is able to retrieve the message. After this time any change of instructions to a proxy appointed through CREST should be communicated to the proxy by other means. CREST Personal Members or other CREST sponsored members and those CREST Members who have appointed a voting service provider(s) should contact their CREST sponsor or voting service provider(s) for assistance with appointing proxies via CREST. For further information on CREST procedures, limitations and system timings, please refer to the CREST Manual. The Company may treat a proxy appointment sent by CREST as invalid in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.
• 1. The Company specifies that only those holders of Ordinary shares of 25p each, registered in the register of members of the Company at close of business on Wednesday 3 May 2017 (or, in the event that the Meeting is adjourned, in the register of members at close of business on the day which is two days (excluding any part of a day that is not a working day) before the day of the adjourned Meeting) shall be entitled to attend and vote at the Meeting in respect of the number of Ordinary shares registered in their names at that time. Changes to entries on the register of members after close of business on Wednesday 3 May 2017 (or, in the event that the Meeting is adjourned, in the register of members after close of business on the day which is two days (excluding any part of a day that is not a working day) before the day of the adjourned Meeting) shall be disregarded in determining the rights of any person to attend or vote at the Meeting.
• 1. The proxy form must be signed. In the case of joint accounts, one holder may sign the proxy form. The vote of the senior who tenders a vote will be taken to the exclusion of all others.
• 1. In the case of a corporation, this form must be executed either under its common seal or under the hand of an Officer or Attorney duly authorised.
• 1. In the case of joint holders of Ordinary shares any one of such holders may vote at the Meeting, either personally or by proxy, in respect of those shares, and if more than one of such joint holders is present at the Meeting, either personally or by proxy, the joint holder whose name stands first on the register as one of such holders shall be entitled to vote in respect thereof.
• 1. Except as provided above, members who wish to communicate with the Company in relation to the Meeting should do so using the means set out in the notes to the Notice of Meeting. No other methods of communication will be accepted. In particular you may not use any electronic address provided either in this proxy form or in any related documents to communicate with the Company for any purposes other than those expressly stated.
