Notes

• 1. As a member of the Company you are entitled to appoint a proxy to exercise all or any of your rights to attend, speak and vote at a general meeting of the Company. You can only appoint a proxy using the procedures set out in these notes.
• 1. Appointment of a proxy does not preclude you from attending the meeting and voting in person. If you have appointed a proxy and attend the meeting in person, your proxy appointment will automatically be terminated.
• 1. A proxy does not need to be a member of the Company but must attend the meeting to represent you. To appoint as your proxy a person other than the Chairman of the meeting, insert their full name in the box. If you sign and return this proxy form with no name inserted in the box, the Chairman of the meeting will be deemed to be your proxy. Where you appoint as your proxy someone other than the Chairman, you are responsible for ensuring that they attend the meeting and are aware of your voting intentions. If you wish your proxy to make any comments on your behalf, you will need to appoint someone other than the Chairman and give them the relevant instructions directly.
• 1. You may appoint more than one proxy provided each proxy is appointed to exercise rights attached to different shares. You may not appoint more than one proxy to exercise rights attached to any one share. To appoint more than one proxy you may photocopy this form. Please indicate the proxy holder's name and the number of shares in relation to which they are authorised to act as your proxy (which, in aggregate, should not exceed the number of shares held by you). Please also indicate 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. To direct your proxy how to vote on the resolutions mark the appropriate box with an 'X'. To abstain from voting on a resolution, select the relevant "Vote withheld" box. 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. If no voting indication is given, your proxy will vote or abstain from voting at his or her discretion. Your proxy will vote (or abstain from voting) as he or she thinks fit in relation to any other matter which is put before the meeting.
• 1. To appoint a proxy using this form, the form must be completed and signed, sent or delivered to Capita Asset Services, 34 Beckenham Road, London, BR3 4TU to be received no later than 12:00 p.m. (BST) (13:00 p.m (CET)) on Friday 24 June 2016.
• 1. In the case of a member which is a company, this proxy form must be executed under its common seal or signed on its behalf by an officer of the company or an attorney for the company.
• 1. Any power of attorney or any other authority under which this proxy form is signed (or a duly certified copy of such power or authority) must be included with the proxy form.
• 1. As an alternative to completing this hard-copy proxy form, you can appoint a proxy electronically by visiting www.capitashareportal.com and following the instructions. For an electronic proxy appointment to be valid, your appointment must be received by Capita Asset Services no later than 12:00 p.m. (BST) (13:00 p.m. (CET)) on Friday 24 June 2016.
• 1. CREST members who wish to appoint a proxy or proxies by using the CREST electronic appointment service may do so by using the procedures described in the CREST Manual. To be valid, the appropriate CREST message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instructions given to a previously appointed proxy, must be transmitted so as to be received by our agent Capita Asset Services (RA10) by 12:00 p.m. (BST) (13:00 p.m. (CET)) on Friday 24 June 2016. See the notes to the notice of meeting for further information on proxy appointment through CREST.
• 1. In the case of joint holders, where more than one of the joint holders purports to appoint a proxy, only the appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names of the joint holders appear in the Company's register of members in respect of the joint holding (the firstnamed being the most senior).
• 1. If you submit more than one valid proxy appointment, the appointment received last before the latest time for the receipt of proxies will take precedence.
• 1. For details of how to change your proxy instructions or revoke your proxy appointment see the notes to the notice of meeting.
• 1. You may not use any electronic address provided in this proxy form to communicate with the Company for any purposes other than those expressly stated.
