Notes for completion of Form of Proxy

• 1 You are entitled to appoint a proxy or proxies of your own choice to exercise all or any of your rights to attend, speak and vote on your behalf at the meeting. A proxy need not be a member of the Company. If you wish to appoint as your proxy somebody other than the Chairman of the meeting, please delete the words "the Chairman of the Annual General Meeting" and insert the name of your chosen proxy holder in the space provided in the first box. Please initial the amendment. The proxy must attend the meeting in person to represent you. The completion of a Form of Proxy does not preclude you from attending or voting in person if you so wish.
• 2 If the proxy is being appointed in relation to less than your full voting entitlement, please enter the number of shares over which they are authorised to act as your proxy in the box next to the proxy's name. If this box is left blank your proxy will be deemed to be authorised in respect of your full voting entitlement (or if this Form of Proxy has been issued in respect of a designated account for a shareholder, the full voting entitlement for that designated account).

• 3 A member can appoint more than one proxy in relation to the meeting, provided that each proxy is appointed to exercise the rights attaching to different shares held by that member. To appoint more than one proxy, you must complete a separate Form of Proxy for each proxy unless you are appointing the proxies electronically in which case, please refer to note 5. Additional Form(s) of Proxy may be obtained by contacting the Company's registrars, Equiniti, or you may photocopy this form. Please indicate in the box next to the proxy holder's name the number of shares in relation to which they are authorised to act as your proxy. Please also indicate by ticking the box provided if the proxy instruction is one of multiple instructions being given. If returned by post, all forms must be signed and returned together in the same envelope addressed to Equiniti, Freepost SEA10846, Aspect House, Spencer Road, Lancing, West Sussex BN99 6ZL.

• 4 If you do not indicate how you wish your proxy to use your vote on any particular matter, the proxy will exercise his or her discretion both as to how he or she votes and whether or not he or she abstains from voting, as he or she will on any other matter arising at the relevant meeting.

• 5 Forms of Proxy, to be valid, must be returned by one of the following methods:
• in hard copy form by post, by courier or by hand to the offices of the Company's registrars, Equiniti, Aspect House, Spencer Road, Lancing, West Sussex BN99 6LQ not later than 11am on Sunday 17th July 2011; or

• in the case of CREST members, by utilising the CREST electronic proxy appointment service in accordance with the procedures set out in the Notice of Meeting and the CREST Manual on the Euroclear website (www.euroclear.com/CREST).
• 6 The 'Vote Withheld' option is to enable you to abstain from any of the specified resolutions. A 'Vote Withheld' has no legal effect and will count neither for nor against a resolution.
• 7 In the case of joint holders, this Form of Proxy may be signed by any of the holders but, if more than one holder votes, the vote of the first named on the Register of Members will be accepted to the exclusion of the votes of the other joint holders.
• 8 In the case of a corporation, this Form of Proxy must be executed under its common seal or under the hand of a duly authorised officer or other person duly authorised for that purpose. In the case of an individual, this Form of Proxy must be signed by the appointer or the appointer's agent, duly authorised in writing.
• 9 The completion and return of this Form of Proxy will not preclude a member from attending the meeting and voting in person.
