NOTES TO THE NOTICE OF ANNUAL GENERAL MEETING Entitlement to attend and vote

1. Pursuant to Regulation 41 of the Uncertificated Securities Regulations 2001 and paragraph 18 (c) of The Companies Act 2006 (C onsequential Amendments) (Uncertificated Securities) Order 2009, the Company specifies that only those members registered on the Company's register of members at:

11. 0 0 am on 21 S ept em b er 20 1 5; or,

if this Meeting is adjourned, 48 hours excluding non working days prior to the adjourned meeting, shall be entitled to attend and vote at the Meeting.

Appointment of proxies

2. If you are a member of the Company at the time set out in note 1 above, you are entitled to appoint a proxy to exercise all or any of your rights to attend, speak and vote at the Meeting and you should have received a proxy form with this notice of meeting. You can only appoint a proxy using the procedures set out in these notes and the notes to the proxy form.
3. A proxy does not need to be a member of the Company but must attend the Meeting to represent you. Details of how to appoint the Chairman of the Meeting or another person as your proxy using the proxy form are set out in the notes to the proxy form. 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 Chairman) and give your instructions directly to them.
4. You may appoint more than one proxy provided each proxy is appointed to exercise rights attached to different shares. You may not appoint more than one proxy to exercise rights attached to any one share. To appoint more than one proxy, you may photocopy the proxy form. Please indicate the proxy holder's name and the number of shares in relation to which they are authorised to act as your proxy (which, in aggreg ate, should not exceed the number of shares held by you). Please also indicate 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. Failure to specify the number of shares to which each proxy appointment relates or specifying more shares than the number of shares held by you at the time set out in note 1 above will result in the proxy appointments b eing invalid.
5. A vote withheld is not a vote in law, which means that the vote will not be counted in the calculation of votes for or against the resolution. If no voting indication is given, your proxy will vote or abstain from voting at his or her discretion. Your proxy will vote (or abstain from voting) as he or she thinks fit in relation to any other matter which is put before the Meeting.

Appointment of proxy using hard copy proxy form

6. The notes to the proxy form explain how to direct your proxy how to vote on each resolution or withhold their vote.
To appoint a proxy using the proxy form, the form must be:

c om p l et ed a n d s i g n e d ;

sent or delivered t o Share Registrars, Suit e E First Floor, 9 Lion & Lamb Y ard, Farnham, Surrey GU9 7LL; and

rec eived by Share Regist rars no lat er than 21 S ept ember 2015 at 11:00 am.

CREST members should use the CREST electronic proxy appointment service and refer to note 8 below in relation to the submission of a proxy appointment via CREST.
In the case of a member which is a company, the proxy form must be executed under its common seal or signed on its behalf by an officer of the company or an attorney for the company.
Any power of attorney or any other authority under which the proxy form is signed (or a duly certified copy of such power or authority) must be included with the proxy form.
2
In each case the proxy appointment must be received not less than 48 hours before the time for the holding of the Meeting or adjourned meeting together (excluding non-working days) with any authority (or a duly certified copy of such authority) under which it is signed.

Appointment of proxies through CREST

8. As an alternative to completing the hardcopy proxy form, CREST members who wish to appoint a proxy or proxies by utilising th e CREST electronic proxy appointment service may do so for the Meeting and any adjournment(s) of it by using the procedures described in the CREST Manual. CREST personal members or other CREST sponsored members, and those CREST members who have appointed a voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.
In order for a proxy appointment made by means of CREST to be valid, the appropriate CREST message (a "CREST Proxy Instruction") must be properly authenticated in accordance with Euroclear UK & Ireland Limited's ("EUI") specifications and must contain the information required for such
instructions, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy
or an amendment to the instruction given to a previously appointed proxy, must, in order to be valid, be transmitted so as to be received by the Company's agent (ID: 7RA36) by not later than 48 hours prior to the time appointed for the Meeting or adjourned meeting excluding days which are non-working days. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the Company's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.
CREST members and, where applicable, their CREST sponsors or voting service providers should note that EUI does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed a voting service provider(s), to procure that his CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members
and, where applicable, their CREST sponsors or voting service providers are referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings.
The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the
Uncertificated Securities Regulations 2001.

Appointment of proxy by joint members

9. In the case of joint holders, where more than one of the joint holders purports to appoint a proxy, only the appointment subm itted by the most senior holder will be accepted. Seniority is determined by the order in which the n ames of the joint holders appear in the Company's register of members in respect of the joint holding (the first-named being the most senior).

Changing proxy instructions

10. To change your proxy instructions simply submit a new proxy appointment using the met hods set out above. Note that the cut-off time for receipt of proxy appointments (see above) also apply in relation to amended instructions; any amended proxy appointment received after the relevant cut-off time will be disregarded.
Where you have appointed a proxy using the hard-copy proxy form and would like to change the instructions using another hard- copy proxy form, please contact Share Registrars, PXS, Suite E First Floor, 9 Lion & Lamb Yard, Farnham, Surrey GU9 7LL, tel. 01252 821390.
If you submit more than one valid proxy appointment, the appointment received last before the latest time for the receipt of proxies will t ake precedence.

Termination of proxy appointments

11. In order to revoke a proxy instruction you will need to inform the Company by sen ding a signed hard copy notice clearly stating your intention to revoke your proxy appointment to Share Registrars, Suite E First Floor, 9 Lion & Lamb Yard, Farnham, Surrey GU9 7LL. In the case of a member which is a company, the revocation notice must be executed under its common seal or signed on its behalf by an officer of the company or an attorney for the company. Any power of attorney or any other authority under which the revocation notice is signed (or a duly certified copy of such power or authority) must be included with the revocation notice.
The revocation notice must be received by Share Registrars not less than 48 hours excluding non working days before the time for holding the Meeting or adjourned meeting.
If you attempt to revoke your proxy appointment but the revocation is received after the time specified then, subject to the paragraph directly below, your proxy appointment will remain valid.
Appointment of a proxy does not preclude you from attending the Meeting and voting in person. If you have appointed a proxy and attend the Meeting in person, your proxy appointment will automatically be terminated.

Corporate representatives

12. A corporation which is a member can appoint one or more corporate representatives who may exercise, on its behalf, all its powers as a member provided that no more than one corporate representative exercises powers over the same share.
