• 1. Full details of the resolutions to be proposed at the 2020 Annual General Meeting (the "AGM"), with explanatory notes, are set out in the Notice of Meeting (the "Notice").
• 1. A shareholder entitled to attend and vote at the AGM is entitled to appoint another person as his/her proxy to exercise all or any of his/her rights to attend and speak and vote at the AGM. A shareholder may appoint more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that shareholder. Proxies need not be shareholders of the Company.
• 1. To appoint more than one proxy, (an) additional proxy form(s) may be obtained by contacting the Registrar on 0371 384 2335 or, if calling from outside the UK, +44 121 415 7047. Lines are open from 8.30am to 5.30pm Monday to Friday. Alternatively, you may photocopy the Form. 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.

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 if the Form has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account).
• 1. The "Vote Withheld" option is provided to enable the appointor to withhold his/her vote on any particular resolution. It should be noted that a withheld vote is not considered to be a vote in law and will not be counted in the proportion of votes "For" and "Against" a resolution.
• 1. The Form (i) in the case of an individual, must either be signed by the appointor or his/her attorney; and (ii) in the case of a corporation, must be either given under its common seal or be signed on its behalf by an attorney or a duly authorised officer of the corporation.

Where an appointment of a proxy is signed on behalf of the appointor by an attorney, the power of attorney or a copy thereof certified notarially or in some other way approved by the Directors must (failing previous registration with the Company) be submitted to the Company, failing which the appointment may be treated as invalid.

In each case, changes to the register of members after such time will be disregarded in determining the rights of any person to attend and vote at the AGM.
• 1. In the case of joint holders, only one need sign the Form but, if more than one holder votes, the vote of the senior holder who tenders a vote will be accepted to the exclusion of the other joint holders. For this purpose, seniority will be determined by the order in which the names stand in the register of members in respect of the joint holding.
• 1. Any proxy appointed pursuant to the Form will vote as indicated by the Form. For any other business arising at the AGM, including any proper procedural resolution not listed on the Notice, the proxy will vote at his/her discretion.
