EXPLANATORY NOTES TO THE RESOLUTIONS:

1. Resolution 1: To receive the 2011 Report and Accounts

The directors of the Company are required to lay the annual Report and Accounts before the shareholders each year at the Annual General Meeting.

A copy of the 2011 Report and Accounts is enclosed. The 2011 Report and Accounts is also available to view, print or download on the Company’s website at www.enquest.com, using Adobe Acrobat or Adobe Acrobat Reader.

2. Resolutions 2 to 8: Re-election of Directors

With regard to the retirement and re-election of directors, the Company is governed by its Articles of Association, the Combined Code on Corporate Governance and the Companies Act 2006. Directors have the power to appoint a director during the year but any person so appointed must stand for election at the next Annual General Meeting. A retiring director is eligible to stand for re-election.

Accordingly, save for Robin Pinchbeck who is retiring at this Annual General Meeting and not standing for re-election, all of the current directors of the Company, each of whom was elected during the course of the year and whose biographical details are set out on pages 38 and 39 of the 2011 Annual Report and Accounts, are standing for re-election at this Annual General Meeting.

The Directors are fully committed to supporting the principles of good governance outlined in the UK Corporate Governance Code (the “ Code ”) which was published by the Financial Reporting Council in June 2010 and which replaces the existing Combined Code on Corporate Governance for accounting periods beginning on or after 29 June 2010. The Code recommends that all directors of FTSE 350 companies should be subject to annual election by shareholders. The Directors have decided to adopt this provision of the Code early, on a voluntary basis and confirm that, save for Robin Pinchbeck who is retiring and not standing for re-election, all of the directors standing for reelection would have been subject to re-election by shareholders at this Annual General Meeting were they not otherwise subject to re-election by virtue of their having been elected by Directors during the year.

The Board has confirmed, following a performance review, that each Director standing for re-election continues to perform effectively and demonstrates commitment to his role.

Short biographical details, together with reasons for the re-election of the non-executive directors standing for reelection are given below:

Dr James Buckee: James Buckee holds a BSc Honours degree in Physics from the University of Western Australia and a PhD in Astrophysics from Oxford University.

3. Resolution 9: To reappoint the auditors and to authorise the Board to agree the auditors’ remuneration

The Company is required to appoint auditors at each general meeting at which accounts are laid before the Company, to hold office until the conclusion of the next such meeting.

The Audit Committee has reviewed the effectiveness, independence and objectivity of the external auditors, Ernst & Young LLP, on behalf of the Board, who now propose their reappointment as auditors of the Company.

This resolution also authorises the directors, in accordance with standard practice, to negotiate and agree the

remuneration of the auditors. In practice, the Audit Committee will consider and approve the audit fees on behalf of the Board.

4. Resolution 10: To authorise the Board to agree the Directors’ remuneration report

This resolution is to approve the directors’ remuneration for the financial year ended on 31 December 2011. You can find the report on pages 49 to 52 of the 2011 Annual Report and Accounts.

5. Resolution 11: Political donations and political expenditure

This resolution is designed to deal with rules on political donations and expenditure contained in Part 14 of the

Companies Act 2006 (the “Act”) (Sections 362 to 379). Under section 366 of the Act, the Company is required to seek shareholders’ authority for any political donations and/or political expenditure made by the Company in the European Union.

Although the Company does not make and does not intend to make political donations to political parties or political organisations or independent election candidates, or to incur political expenditure, the legislation is very broadly drafted and may catch such activities as funding seminars or functions to which politicians are invited, or may extend to bodies concerned with policy review, law reform and representation of the business community that the Company and its subsidiaries might wish to support. Accordingly, the directors have decided to seek shareholders’ authority for political donations and political expenditure in case any of the Company’s activities in its normal course of business are caught by the legislation.

The authority sought would be capped at $100,000 for the next year. This authority will cover the period from the date Resolution 11 is passed until the end of the next Annual General Meeting of the Company in 2012, or if earlier, on 25 August 2012. As permitted under the Act, Resolution 11 also covers any political donations made, or any political expenditure incurred by any subsidiaries of the Company. The directors will continue to seek to renew their authority at each Annual General Meeting, in accordance with current best practice.

6. Resolution 12: Authority to allot

Your directors may allot shares and grant rights to subscribe for, or convert any security into, shares only if authorised to do so by shareholders. The authority granted at the last General Meeting is due to expire at this year’s Annual General Meeting. Accordingly, Resolution 12 will be proposed as an ordinary resolution to grant new authorities to allot shares and grant rights to subscribe for, or convert any security into, shares. If given, these authorities will expire at the Annual General Meeting in 2012 or on 25 August 2012, whichever is the earlier.

Paragraph (a) of Resolution 12 will allow the directors to allot ordinary shares up to a maximum nominal amount of £13,324,381, representing approximately one third (33.33 per cent.) of the Company’s existing issued share capital and calculated as at 4 April 2011 (being the latest practicable date prior to publication of this document). In accordance with the latest institutional guidelines issued by the Association of British Insurers, paragraph (b) of Resolution 12 will also allow directors to allot, including the ordinary shares referred to in paragraph (a) of Resolution 12, further ordinary shares in connection with a pre-emptive offer by way of a rights issue to ordinary shareholders up to a maximum nominal amount of £26,648,762, representing approximately two thirds (66.67 per cent.) of the Company’s existing issued share capital calculated as at 4 April 2011. The directors have no present intention of exercising this authority. However, if they do exercise the authority, the directors intend to follow emerging best practice as regards its use as recommended by the Association of British Insurers.

7. Resolution 13: Disapplication of pre-emption rights

Your directors also require a power from shareholders to allot equity securities or sell treasury shares for cash and otherwise than to existing shareholders pro rata to their holdings. The power granted at the last General Meeting is due to expire at this year’s Annual General Meeting. Accordingly, Resolution 13 will be proposed as a special resolution to grant such a power. Apart from offers or invitations in proportion to the respective number of shares held, the power will be limited to the allotment of equity securities and sales of treasury shares for cash up to an aggregate nominal value of £1,998,657 (being five per cent. of the Company’s issued ordinary share capital at 4 April 2011, the latest practicable date prior to publication of this notice). If given, this power will expire on 25 August 2012 or at the conclusion of the Annual General Meeting in 2012, whichever is the earlier. Your directors will have due regard to institutional guidelines in relation to any exercise of this power, in particular the requirement for advance consultation and explanation before making any non pre-emptive cash issue pursuant to this resolution which exceeds 7.5 per cent. of the Company’s issued share capital in any rolling three-year period.

8. Resolution 14: Authority to purchase own shares

This resolution will give the Company authority to purchase its own shares in the markets up to a limit of ten per cent. Of its issued ordinary share capital. The maximum and minimum prices are stated in the resolution. Your directors believe that it is advantageous for the Company to have this flexibility to make market purchases of its own shares. Your directors will exercise this authority only if they are satisfied that a purchase would result in an increase in expected earnings per share and would be in the interests of shareholders generally.

In the event that shares are purchased, they would either be cancelled (and the number of shares in issue would be reduced accordingly) or, in accordance with the Companies Act 2006, be retained as treasury shares. The Company may consider holding repurchased shares pursuant to the authority conferred by this resolution as treasury shares. This would give the Company the ability to transfer treasury shares quickly and cost effectively and would provide the Company with additional flexibility in the management of its capital base.

9. Resolution 15: Notice to general meeting.

Changes made to the Companies Act 2006 by the Companies (Shareholders’ Rights) Regulations 2009 increase the notice period required for general meetings of the Company to at least 21 clear days unless shareholders approve a shorter notice period, which cannot however be less than 14 clear days. Annual General Meetings will continue to be held on at least 21 clear days’ notice.

Until the Companies (Shareholders’ Rights) Regulations 2009 came into force on 3 August 2009, the Company was able to call general meetings other than an annual general meeting on at least 14 clear days’ notice without obtaining such shareholder approval. In order to preserve this ability, Resolution 15 seeks the necessary shareholder approval. The approval will be effective until the Company’s next Annual General Meeting, when it is intended that a similar resolution will be proposed.

The flexibility offered by this resolution will be used where, taking into account the circumstances, the directors

consider this appropriate in relation to the business to be considered at the meeting.

Please note that the changes to the Companies Act 2006 mean that, in order to be able to call a general meeting on less than 21 clear days’ notice, the Company must make a means of electronic voting available to all shareholders for that meeting.

Recommendation

Your directors believe that all the proposed resolutions are in the best interests of the Company and its shareholders as a whole. Accordingly, your directors unanimously recommend that you vote in favour of them as they intend to do in respect of their own beneficial holdings.

COMPANY SECRETARY

Registered Office: Rex House, 4-12 Regent Street, London SW1Y 4PE

Registered in England and Wales No. 07140891

NOTES:

1. Pursuant to regulation 41 of the Uncertificated Securities Regulations 2001, the Company specifies that in order to have the right to attend and vote at the Annual General Meeting (and also for the purpose of determining how many votes a person entitled to attend and vote may cast), a person must be entered on the register of members of the Company at 6.00 p.m. on Monday 23 May 2011 or, in the event of any adjournment, at 6.00 p.m. on the date which is two days before the day of the adjourned meeting. Changes to entries on the register of members after this time shall be disregarded in determining the rights of any person to attend or vote at the meeting.

2. A member is entitled to appoint another person as his proxy to exercise all or any of his rights to attend, to speak and to vote at the Annual General Meeting. A member may appoint more than one proxy in relation to the meeting, provided that each proxy is appointed to exercise the rights attached to a different share or shares held by him. A proxy need not be a member of the Company. A form of proxy for the meeting is enclosed.

To be valid any proxy form or other instrument appointing a proxy must be received by post or by hand (during normal business hours only) in accordance with the instructions printed on the form of proxy to arrive no later than 2.00 p.m. on 23 May 2011. If you are a CREST member, see note 3 below.

Completion of a form of proxy, or other instrument appointing a proxy or any CREST Proxy Instruction will not preclude a member attending and voting in person at the meeting if he/she wishes to do so.

3. Alternatively, if you are a member of CREST, you may register the appointment of a proxy by using the CREST electronic proxy appointment service. Further details are contained below.

CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the Annual General Meeting and any adjournment(s) thereof by using the procedures, and to the address, described in the CREST Manual (available via www.euroclear.com/CREST) subject to the provisions of the Company’s articles of association. 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 or instruction made using the CREST service to be valid, the appropriate CREST message (a “CREST Proxy Instruction”) must be properly authenticated in accordance with Euroclear UK and Ireland Limited’s (“Euroclear”) 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 issuer’s agent (ID RA10) by 2.00 p.m. on 23 May 2011. For this purpose, the time of receipt will be taken to be the time (as determined by the time stamp applied to the message by the CREST Applications Host) from which the issuer’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 provider(s) should note that Euroclear 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 provider(s) 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.

4. Any person to whom this notice is sent who is a person nominated under section 146 of the Companies Act 2006 to enjoy information rights (a “Nominated Person”) may have a right, under an agreement between him/her and the member by whom he/she was nominated, to be appointed (or to have someone else appointed) as a proxy for the Annual General Meeting. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may have a right, under such an agreement, to give instructions to the member as to the exercise of voting rights.

The statement of the above rights of the members in relation to the appointment of proxies does not apply to Nominated Persons. Those rights can only be exercised by members of the Company.

5. Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of its powers as a member provided that they do not do so in relation to the same shares.

6. Any member attending the Annual General Meeting has the right to ask questions. The Company must cause to be answered any such question relating to the business being dealt with at the meeting but no such answer need be given if (a) to do so would interfere unduly with the preparation for the meeting or involve the disclosure of confidential information, (b) the answer has already been given on a website in the form of an answer to a question, or (c) it is undesirable in the interests of the company or the good order of the meeting that the question be answered.

7. Copies of executive directors’ service agreements and copies of the terms and conditions of appointment of non executive directors are available for inspection at the Company’s registered office during normal business hours from the date of this notice until the close of the Annual General Meeting (Saturdays, Sundays and public holidays excepted) and will be available for inspection at the place of the meeting for at least 15 minutes prior to and during the meeting. A copy of this notice, and other information required by section 311A of the Companies Act 2006, can be found at www.enquest.com.

8. Under section 527 of the Companies Act 2006 (the “Act”), members meeting the threshold requirements set out in that section have the right to require the Company to publish on a website a statement setting out any matter relating to: (i) the audit of the Company’s accounts (including the auditor’s report and the conduct of the audit) that are to be laid before the Annual General Meeting; or (ii) any circumstance connected with an auditor of the Company ceasing to hold office since the previous meeting at which annual accounts and reports were laid in accordance with section 437 of the Act, (in each case) that the members propose to raise at the Annual General Meeting. The Company may not require the members requesting any such website publication to pay its expenses in complying with sections 527 or 528 of the Act. Where the Company is required to place a statement on a website under section 527 of the Act, it must forward the statement to the Company’s auditor not later than the time when it makes the statement available on the website. The business which may be dealt with at the meeting includes any statement that the Company has been required under section 527 of the Act to publish on a website.

9. As at 4 April 2011 (being the last practicable date prior to the publication of this notice) the Company’s issued share capital consists of 799,462,905 ordinary shares, carrying one vote each. Therefore, the total voting rights in the Company as at that date are 799,462,905.

10. You may not use any electronic address (within the meaning of section 333(4) of the Companies Act 2006) provided in this Notice of Meeting (or in any related documents and proxy form) to communicate with the Company for any purposes other than those expressly stated.
