Explanatory notes to the proxy form

• 1. In line with the government's restrictions on public gatherings, physical attendance at the 2020 AGM will not be permitted. However shareholders and duly appointed proxies will be able to participate electronically. Instructions on how to view the webcast electronically are included on this Proxy Card and in the Notice of Meeting. Every shareholder has the right to appoint some other person(s) of his or her choice, who need not be a shareholder, as his or her proxy to exercise all or any of his or her rights, to vote electronically and submit questions on their behalf at the meeting. If you wish to appoint a person other than the Chairman, please insert the name of your chosen proxy holder in the space provided. If the proxy is being appointed in relation to less than your full voting entitlement, please enter, in the box below the proxy holder's name, the number of shares in relation to which they are authorised to act as your proxy. If this box is left blank, your proxy will be deemed to be authorised in respect of your full voting entitlement (or if this proxy form has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account).
• 1. The proxy form gives your proxy or proxies full rights to vote electronically and also to submit questions on their behalf at the AGM. If you wish to restrict the rights of the Chairman as your proxy, please cross out either or both of the words 'speak' and 'vote' in the first paragraph of the proxy form, as you feel appropriate.

• 1. The 'Vote withheld' boxes are provided to enable you to abstain from voting on any particular resolution. You should note, however, that a 'Vote withheld' is not a vote in law and will not be counted in determining the proportion of votes cast 'For' and 'Against' a resolution on a poll, but will be counted in determining if a quorum is present.

In the case of a corporation, the appointment of a proxy must be executed either under its common seal or by a duly authorised officer or agent. In the case of joint holders, any holder may sign. The vote of a more senior joint holder on the Register will be accepted to theexclusion of a junior joint holder. For this purpose, the order in which the names of the joint holders are recorded in the register of members will determine seniority.
