Notes on appointing a proxy

• 1. If you wish to appoint as your proxy someone other than the Chairman of the Meeting, insert his/her name in the space provided in the first box on the proxy form. If the proxy is being appointed in relation to part of your holding only, enter the number of shares over which he/she is authorised to act as your proxy in the box next to the proxy's name. If this box is left blank, he/she will be authorised in respect of your full voting entitlement.
• 1. To appoint more than one proxy, you should obtain additional proxy forms from the company's registrar, Equiniti, or you may photocopy the proxy form. Ensure that you specify the number of shares over which each proxy can act, as in Note 1 above. Multiple proxy forms must be returned together in the same envelope.
• 1. To be valid, the proxy form and the power of attorney or other authority (if any) under which it is signed and dated must be received by Equiniti by 3.30pm on Tuesday 1 May 2018.
• 1. The "Vote withheld" option is provided to enable a member to withhold his/her vote on the resolution. 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 votes "For" or "Against" the resolution.
• 1. To register the appointment of a proxy electronically, log on to www.sharevote.co.uk using the Voting ID, Task ID and Shareholder reference number printed overleaf and follow the instructions provided. The proxy appointment must be registered on the website by 3.30pm on Tuesday 1 May 2018.
• 1. In the case of a corporate shareholder, the proxy appointment must be under seal or signed by a duly authorised officer, attorney or other person.
• 1. In the case of joint holdings, the vote of the first named in the register of members will be accepted to the exclusion of other joint holders.
• 1. If no specific directions are given, the proxy will vote or abstain from voting as he/she thinks fit on the specified resolution and, unless instructed otherwise, the person appointed proxy may also vote or abstain from voting as he/she thinks fit on any business (including amendments to the resolution) which may properly come before the Meeting.
• 1. A proxy need not be a member of the company, but must attend the Meeting to represent you. If no name is inserted in the box provided, the Chairman of the Meeting will be deemed to be appointed as the proxy.
• 1. Any alteration to the proxy form should be initialled by the person who signed it.
• 1. If you do not wish anyone other than the company or Equiniti to see the proxy form you may send it in an envelope to: FREEPOST RTHJ-CLLL-KBKU, Equiniti, Aspect House, Spencer Road, Lancing, BN99 8LU (no stamp is needed if posted within the United Kingdom).
