Explanatory 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 the meeting and any adjournment of it. You may appoint more than one proxy provided that each proxy is appointed to exercise the rights attached to different shares held by you. However, you may only appoint any proxy using the procedures set out in these notes and in the Notice of Annual General Meeting. To appoint more than one person to act as your proxy, you may photocopy this form and must clearly state on each form how many shares the proxy is appointed in respect of (which, in aggregate, should not exceed the total number of shares held by you).

2. 1. If you wish your proxy to speak on your behalf at the meeting, you will need to appoint your own choice of proxy (not the Chair of the meeting) by selecting the appropriate option above, entering their name in the space provided and giving your instructions directly to them. A proxy need not be a member of the Company. The appointment of a proxy will not preclude you from attending and voting at the meeting in person should you so decide, but in such event, your proxy appointment(s) will automatically be terminated unless you notify the Company otherwise upon your arrival.
3. 1. You may specify how you wish your vote(s) to be cast on each of the resolutions by placing a mark in the appropriate boxes in the table above. Where you either specify the "Discretionary" option, or do not specify any option at all, your proxy will, on receipt by the Company of this proxy

form, duly signed, be authorised to vote, or abstain from voting, as he/she thinks fit. Your proxy can also do this on any other resolution that is properly put to the meeting but not referred to above.

• 1. The "Withheld" option is provided to enable you to instruct your proxy not to vote on any particular resolution. A vote withheld in this way 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.
• 1. A corporation may execute this proxy form under its common seal or under the hand of a duly authorised officer or attorney. In the case of joint shareholders, the names of both or all the joint holders should be stated but the signature of the first named holder on the register of members will be accepted to the exclusion of any other joint holder.
• 1. To be valid, your proxy form must be properly completed and signed and delivered (together with the power of attorney or other authority, if any, under which it is signed or a duly certified copy of such power or authority) to Equiniti, Aspect House, Spencer Road, Lancing BN99 6DA. As an alternative, you may appoint a proxy electronically by authenticated email (attaching the documents referred to above) sent to proxyvotes@equiniti.com. Please state "Gresham AGM" in the subject line of the e-mail. In either case, the form must be received not later than 11.00am on 6 May 2022 (being 48 hours before the time fixed for the meeting, excluding non-working days).
