Explanatory Notes:

• 1. Every holder has the right to appoint some other person(s) of their choice, who need not be a shareholder, as his proxy to exercise all or any of his rights, to listen and vote on their behalf at the meeting. However, in light of the Coronavirus pandemic situation, ordinary shareholders and their proxies will not be allowed to attend the meeting in person and so shareholders are encouraged to appoint the Chairman as their proxy for the meeting. 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 (see reverse) the number of shares in relation to which they are authorised to act as your proxy. If returned without an indication as to how the proxy shall vote on any particular matter, the proxy will exercise his discretion as to whether, and if so how, he votes (or if this proxy form has been issued in respect of a designated account for a shareholder, the proxy will exercise his discretion as to whether, and if so how, he votes in respect of that designated account.).
• 2. The Board would strongly recommend you consider carefully the Government's advice and do not attend the meeting. Please vote either online or returning this Form of Proxy.
• 3. The 'Vote Withheld' option overleaf is provided to enable you to abstain on any particular resolution. However, it should be noted that a 'Vote Withheld' is not a vote in law and will not be counted in the calculation of the proportion of the votes 'For' and 'Against' a resolution.
• 4. Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001, entitlement to attend and vote at the meeting and the number of votes which may be

cast thereat will be determined by reference to the Register of Members of the Company at close of business on the day which is two business days before the day of the meeting. Changes to entries on the Register of Members after that time shall be disregarded in determining the rights of any person to attend and vote at the meeting.

• 5. To appoint one or more proxies or to give an instruction to a proxy (whether previously appointed or otherwise) via the CREST system, CREST messages must be received by the issuer's agent (ID number 3RA50) not later than 48 hours (business days) before the time appointed for holding the meeting. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the CREST system) from which the issuer's agent is able to retrieve the message. The Company may treat as invalid a proxy appointment sent by CREST in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.
• 6. The above is how your address appears on the Register of Members. If this information is incorrect please ring the Registrar's helpline on 0370 707 1293 to request a change of address form or go to www.investorcentre.co.uk to use the online Investor Centre service.
