Explanatory Notes:

• 1. Please note the following important information when completing this form of proxy. Under the 'Stay at Home' measures imposed by the UK Government in response to the Covid-19 outbreak, public gatherings of more than two people are currently not permitted. As a result, you will not be permitted to attend the Annual General Meeting in person. Anyone seeking to attend the meeting in person (beyond the two persons designated by the Board as being necessary to form a quorum) will be refused entry. You should appoint the Chairman of the Annual General Meeting as your proxy (any other proxy will not be allowed to attend the meeting unless it is for the purpose of forming the quorum).
• 2. 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.
• 3. Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001, entitlement to vote and the number of votes which may be cast will be determined by reference to the Register of Members of the Company at close of business on the day which is two days before the day of the meeting.
