Explanatory Notes:

1. Every holder has the right to appoint some other person(s) of their choice, who need not be a shareholder, as his proxy to exercise all or any of his rights, to attend, speak and vote 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 (see reverse). If the proxy is being appointed in relation to less than your full voting entitlement, please enter in the box next to the proxy holders name (see reverse) the number of shares in relation to which they are authorised to act as your proxy. If 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).

2. To appoint more than one proxy, an additional proxy form(s) may be obtained by contacting the Registrar's helpline on 0870 707 1046 or you may photocopy this form. Please indicate in the box next to the proxy holder's name (see reverse) the number of shares in relation to which they are authorised to act as your proxy. Please also indicate by marking the box provided if the proxy instruction is one of multiple instructions being given. All forms must be signed and should be returned together in the same envelope.

3. 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.

4. If you want your proxy to vote in a certain way at the meeting on the resolutions specified, please indicate this in the relevant boxes (see reverse). Unless otherwise instructed, your proxy can vote as he or she chooses or can decide not to vote at all. The proxy can also do this on any other resolution that is put to the meeting.

5. In the case of a joint holding, a proxy need only be signed by one joint holder. If more than one such joint holder tenders a vote, whether in person or by proxy, the vote of the senior shall be accepted to the exclusion of the votes of the other joint holders.

Seniority is determined by the order in which the names appear in the Register of Members.

1. Pursuant to regulation 41 of the Uncertificated Securities Regulations 2001, entitlement to attend and vote at the meeting and the number of votes which may be cast thereat 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. Changes to entries on the Register of Members after that time shall be disregarded in determining the rights of any person to attend and vote at the meeting.

2. To appoint one or more proxies or to give an instruction to a proxy (whether previously appointed or otherwise) via the CREST system, CREST messages must be received by the issuer's agent (ID number 3RA50) not later than 48 hours before the time appointed for holding the meeting. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the CREST system) from which the issuer's agent is able to retrieve the message. The Company may treat as invalid a proxy appointment sent by CREST in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

3. The above is how your address appears on the Register of Members. If this information is incorrect please ring the Registrar's helpline on 0870 707 1046 to request a change of address form or go to www.investorcentre.co.uk to use the online Investor Centre service.

4. Any alterations made to this form should be initialled.

5. The completion and return of this form will not preclude a member from attending the meeting and voting in person.
