Dear Shareholder

Fifth Annual General Meeting (AGM) of the Company

I am pleased to enclose the Notice of Meeting for the Company's 2022 Annual General Meeting, which is the Company's fifth AGM.

The purpose of this letter is to provide you with an explanation of the Resolutions to be proposed at the AGM.

All Resolutions apart from Resolutions 15 to 19 are proposed as ordinary resolutions. For each of these to be passed, more than 50 per cent of the votes cast at the meeting must be in favour of the Resolution. Resolutions 15 to 19 are proposed as special resolutions. For each of these to be passed, at least 75 per cent of the votes cast must be in favour of the Resolution. Voting on all Resolutions to be proposed at the AGM will be by way of a poll. This ensures that all shareholders who have appointed proxies will have their votes fully taken into account, despite not being able to attend the AGM in person.

The AGM is an opportunity for Shareholders to express their views directly with the Board and I hope that you will take the opportunity to do so. If you would like to vote on the Resolutions but cannot attend the AGM, please complete the Form of Proxy enclosed with this document and return it to our registrars, Computershare, The Pavilions, Bridgwater Road, Bristol BS99 6ZY, by 11:00 a.m. on Tuesday 24 May 2022.

Resolutions

Ordinary Resolutions

The resolutions that will be considered at the AGM are as follows:

A resolution to receive the Company's annual accounts for the financial year ended 31 December 2021 together with the Directors' report and the Auditors' report on those accounts (resolution 1).

An advisory resolution to approve the Directors' Remuneration Report is proposed (resolution 2). The Directors' Remuneration Report can be found on pages 141 to 159 of the 2021 Annual Report. The Directors' Remuneration Report gives details of the amounts paid or payable to Directors in connection with their performance and the performance of the Company during the year ended 31 December 2021. This resolution is advisory in nature and will not affect the future remuneration that is paid to any Director.

In accordance with the 2018 UK Corporate Governance Code, all of the Directors should be subject to annual re-election. Additionally, the Company's articles of association require the Directors to offer themselves for re-appointment by shareholders at each subsequent Annual General Meeting following their appointment by the Board. As announced on 27 April 2022, Robert Peck will not be offering himself for re-election at this AGM and will retire from the Board at the conclusion of this meeting. Accordingly, resolutions 3 to 11 seek the re-appointment and appointment of all of the other Directors. Biographies of each of the Directors can be found on pages 106 to 110 of the 2021 Annual Report.

Resolution 12 recommends the re-appointment of Ernst & Young LLP as auditors to the Company and Resolution 13 proposes that the Directors be authorised to set their remuneration on the recommendation of the Audit & Risk Committee.

Resolutions 14, 15 and 16 relate to the Directors' authority to issue shares. Resolution 14 seeks to renew the Directors' general authority to allot shares, while resolutions 15 and 16 relate to the ability to issue new shares for cash other than in accordance with statutory pre-emption rights. The extent of these authorities is in line with the Share Capital Management Guidelines issued by the Investment Association. Resolution 16 is intended to give the Company flexibility to make non-pre-emptive issues of shares in connection with acquisitions and other specified capital investments as contemplated by the Pre-Emption Group's Statement of Principles. In accordance with the Pre-Emption Group's Statement of Principles, the Directors confirm that they intend to use the authority sought in Resolution 16 only in connection with an acquisition or specified capital investment that is announced contemporaneously with the issue, or that has taken place in the preceding six-month period and is disclosed in the announcement of the issue. The Directors also confirm their intention to follow the provisions of the Pre-Emption Group's Statement of Principles regarding cumulative usage of authorities within a three-year rolling period where the Principles provide that usage in excess of 7.5% of the Company's issued ordinary share capital should not take place, save as permitted in connection with an acquisition or specified capital investment as described above, without prior consultation with shareholders. The Directors consider that it is appropriate for these authorities and these powers to be granted to preserve maximum flexibility for the future.

Special Resolutions

In addition, a resolution is proposed to retain a notice period of 14 days for general meetings (other than an annual general meeting, which has a longer notice period) (resolution 17).

The Company is seeking authority to make market purchases of its own shares up to an aggregate of 17,804,050 shares (resolution 18).

The Company is seeking approval of a reduction to the Company's share premium account of \$500,000,000.

Recommendation

The Directors consider that all the proposals to be considered at the AGM are in the best interests of the Company and its Shareholders as a whole and are most likely to promote the success of the Company. The Directors unanimously recommend that you vote in favour of all the proposed resolutions, as they intend to do in respect of their own beneficial holdings which represent approximately 22.72% of the issued share capital.

Action to be taken

Shareholders will find enclosed with this document a Form of Proxy for use in connection with the AGM. Shareholders, are requested to complete, sign and return the enclosed Form or Proxy, in accordance with the instructions printed thereon, so as to be received by the Company's registrars, Computershare Investor Services plc, The Pavilions, Bridgwater Road, Bristol BS99 6ZY as soon as possible and, in any event, no later than 11:00 a.m. on Tuesday 24 May 2022. You can also appoint a proxy online and give your voting instructions at www.investorcentre.co.uk/eproxy or through CREST.

Yours faithfully,

Karen Simon

Chairman

EXPLANATION OF RESOLUTIONS

RESOLUTION 1 – TO RECEIVE AND ADOPT THE REPORT AND ACCOUNTS

The Directors are required to present the accounts, Directors' report and Auditors' report to the meeting. These are contained in the Company's Annual Report and Financial Statements for the year ended 31 December 2021.

RESOLUTION 2 – TO APPROVE THE DIRECTORS' REMUNERATION REPORT

The Directors' Remuneration Report for the year ended 31 December 2021 is submitted for approval by the Shareholders, a copy of which can be found on pages 141 to 159 in the 2021 Annual Report. The report gives details of the Directors' remuneration for the year ended 31 December 2021. The Auditors have audited those parts of the Directors' Remuneration Report capable of being audited. Resolution 2 is an advisory vote.

RESOLUTIONS 3 TO 11 – APPOINTMENTS OR RE-APPOINTMENTS OF DIRECTORS

In accordance with the recommendations of the 2018 UK Corporate Governance Code, the Directors appointed at last year's AGM will offer themselves for re-appointment by the Shareholders at the AGM. Resolutions 3 to 10 seek such re-appointments.

Additionally, in accordance with the Company's articles of association, the Director appointed by the Board since the last AGM is required to retire and may then be considered for election. The Director appointed since the last AGM is seeking election through resolution 11 9.

The Board has reviewed the role of each of the Directors and remains satisfied that each of the Directors continues to be fully competent to carry out his or her responsibilities as a member of the Board and that each such Director's performance continues to be effective and demonstrates commitment to the role. Biographies of each of the Directors can be found on pages 106 to 110 of the 2021 Annual Report.

RESOLUTION 12 – RE-APPOINTMENT OF AUDITORS

The Company is required at each general meeting at which the Company's annual report and accounts for the previous financial year are presented to appoint auditors to hold office until the next such meeting. Accordingly, the Board, on the recommendation of the Audit & Risk Committee, recommends to shareholders the re-appointment of Ernst & Young LLP as the Company's auditors.

RESOLUTION 13 – AUDITORS' REMUNERATION

This resolution, which is conditional on the passing of resolution 12, seeks Shareholder consent for the Directors to set the remuneration of the Auditors on the recommendation of the Audit & Risk Committee.

RESOLUTION 14 – AUTHORITY TO ALLOT ORDINARY SHARES

The Company's Directors may only allot Ordinary Shares or grant rights over Ordinary Shares if authorised to do so by the Shareholders. The authority granted at the general meeting of the Company held on 24 May 2021 under section 551 of the Act to allot relevant securities is due to expire at the conclusion of this year's AGM. Accordingly, this resolution seeks to renew the Directors' authority to allot Relevant Securities in accordance with section 551 of the Act.

If passed, the resolution will authorise Directors to allot: (i) in relation to a pre-emptive rights issue only, equity securities (as defined by section 560 of the Act) up to a maximum nominal amount of £1,185,749.76 which represents approximately 66.6% of the Company's issued Ordinary Shares (excluding treasury shares) as at 27 April 2022 (the latest practicable date prior to the date of this document). This maximum is reduced by the nominal amount of any Relevant Securities allotted under the authority set out in paragraph 15b); and (ii) in any other case, Relevant Securities up to a maximum nominal amount of £592,874.88 which represents approximately 33.3% of the Company's issued Ordinary Shares (excluding treasury shares) as at 27 April 2022 (the latest practicable date prior to the date of this

document). This maximum is reduced by the nominal amount of any equity securities allotted under the authority set out in paragraph 15a) in excess of £592,874.88.

The maximum nominal amount of Relevant Securities (including equity securities) that may be allotted under this resolution is £1,185,749.76.

As at close of business on 27 April 2022 (the latest practicable date prior to the date of this document), the Company did not hold any treasury shares.

The authority granted by this resolution will expire at the conclusion of the next annual general meeting of the Company or on 25 August 2023, whichever is earlier.

The Directors have no present intention of exercising the authority granted by this resolution but the authority provides the flexibility to allow them to do so in the future. The Directors would not exercise the authority unless they believed that the expected effect would promote the success of the Company for the benefit of its Shareholders as a whole.

In this resolution, Relevant Securities means:

• a) shares in the Company, other than shares allotted pursuant to:
• a. an employee share scheme (as defined in section 1166 of the Act);
• b. a right to subscribe for shares in the Company where the grant of the right itself constitutes a Relevant Security; or
• c. a right to convert securities into shares in the Company where the grant of the right itself constitutes a Relevant Security; and
• b) any right to subscribe for or to convert any security into shares in the Company other than rights to subscribe or convert any security into shares allotted pursuant to an employee share scheme (as defined in section 1166 of the Act). References to the allotment of Relevant Securities in this resolution include the grant of such rights.

RESOLUTIONS 15 AND 16 – TO AUTHORISE DIRECTORS TO DIS-APPLY PRE-EMPTION RIGHTS

Resolutions 15 and 16 are to approve the disapplication of pre-emption rights. Section 561(1) of the Act provides that if the Directors wish to allot any equity securities, or sell any treasury shares (if it holds any), for cash, they must first offer them to existing shareholders in proportion to their existing shareholdings. Section 561 does not apply to allotments of equity securities made in connection with an employee share scheme.

In accordance with the Pre-Emption Group's Monitoring Report issued in May 2017, two separate resolutions are being proposed in connection with the disapplication of pre-emption rights.

Resolution 15 will, if passed, give the Directors power, pursuant to the authority to allot granted by Resolution 14, to allot equity securities (as defined by section 560 of the Act) or sell treasury shares for cash without first offering them to existing Shareholders in proportion to their existing holdings (a) in relation to pre-emptive offers and offers to holders of other equity securities if required by the rights of those securities or as the Directors otherwise consider necessary, up to a maximum nominal amount of £592,874.88 which represents approximately 33.3% and, in relation to rights issues only, up to a maximum additional amount of £592,874.88 which represents approximately a further 33.3% of the Company's issued Ordinary Shares (excluding treasury shares) as at 27 April 2022 (the latest practicable date prior to the date of this document); and (b) in any other case, up to a maximum nominal amount of £89,020.25 which represents approximately 5% of the Company's issued Ordinary Shares (excluding treasury shares) as at 27 April 2022 (the latest practicable date prior to the date of this document).

The Board considers the authority in Resolution 15 to be appropriate in order to allow the Company flexibility to finance business opportunities or to conduct a pre-emptive offer or rights issue without the need to comply with the strict requirements of the statutory pre-emption provisions.

Resolution 16 will, if passed, give the Directors further power, pursuant to the authority to allot granted by Resolution 14, to allot equity securities or sell treasury shares for cash without first offering them to existing Shareholders in proportion to their existing holdings for transactions which the Directors determine to be an acquisition or specified capital investment defined by the Pre-Emption Group's Statement of Principles, up to a further total amount of £89,020.25 which represents approximately 5% of the Company's issued Ordinary Shares (excluding treasury shares) as at 27 April 2022 (the latest practicable date prior to the date of this document).

In accordance with the Pre-Emption Group's Statement of Principles, the Directors confirm that they intend that such authority will be used only in connection with an acquisition or specified capital investment that is announced contemporaneously with the issue, or that has taken place in the preceding six-month period and is disclosed in the announcement of the issue. This power is being sought in order to give the Company the flexibility to raise funds in the future should it choose to do so. The Directors also confirm, in accordance with the Pre-Emption Group's Statement of Principles, that it does not intend to issue ordinary shares for cash representing more than 7.5% of the Company's issued ordinary share capital in any rolling three-year period other than to existing shareholders, save as permitted in connection with an acquisition or specified capital investment as described above, without prior consultation with shareholders.

These authorities will expire at the conclusion of the next annual general meeting of the Company or on 25 August 2023, whichever is earlier. It is the intention of the Directors to seek to renew these authorities every year and these resolutions will revoke and replace the power granted by Shareholders at last year's annual general meeting.

RESOLUTION 17 – NOTICE OF GENERAL MEETINGS OTHER THAN ANNUAL GENERAL MEETINGS

Under the Act, the notice period required for all general meetings of the Company is 21 clear days. AGMs will always be held on at least 21 clear days' notice but Shareholders can approve a shorter notice period for other general meetings.

This resolution would, if passed, allow the Company flexibility to call general meetings, other than annual general meetings, on not less than 14 clear days' notice. The approval will be effective until the Company's next annual general meeting, when it is intended that a similar resolution will be proposed.

RESOLUTION 18 – TO APPROVE THE PURCHASE OF THE COMPANY'S OWN SHARES

This resolution seeks authority for the Company to make market purchases of its own Ordinary Shares and is proposed as a special resolution. If passed, the resolution gives authority for the Company to purchase up to 17,804,050 of its Ordinary Shares, representing just under 10% of the Company's issued Ordinary Share capital (excluding treasury shares) as at 27 April 2022 (the latest practicable date prior to the date of this document).

The resolution specifies the minimum and maximum prices which may be paid for any Ordinary Shares purchased under this authority. The authority will expire at the conclusion of the next annual general meeting of the Company or on 25 August 2023, whichever is earlier.

The Directors do not currently have any intention of exercising the authority granted by this resolution. The Directors will only exercise the authority to purchase Ordinary Shares where they consider that such purchases will be in the best interests of Shareholders generally and will result in an increase in earnings per Ordinary Share.

The Company may either cancel any shares it purchases under this authority or transfer them into treasury (and subsequently sell or transfer them out of treasury or cancel them).

There are currently no options to subscribe for Ordinary Shares in the Company and the Company does not have any outstanding share warrants.

RESOLUTION 19 – TO APPROVE THE REDUCTION OF THE COMPANY'S SHARE PREMIUM ACCOUNT

This resolution seeks authority for the Company to reduce the amount standing to the credit of the share premium account of the Company by an amount of \$500,000,000.

The share premium account is a non-distributable reserve and the Company is, therefore, unable to use the amount standing to the credit of the share premium account for making distributions to Shareholders. Pursuant to the Act, and subject to the approval by the Shareholders and the High Court of Justice in England and Wales, the Company is able to reduce its share premium account and credit the resulting amount to the Company's profit and loss account, which are distributable reserves. The proposed reduction of the Company's share premium account from \$915,386,917.56 to \$415,386,917.56 and the resultant creation of \$500,000,000.00 of additional distributable reserves provides the Company with additional capacity to pay dividends to Shareholders in accordance with the Company's dividend policy (as announced and fully set out in the Company's 2021 Full Year Results, dated 24 March 2022) . The High Court of Justice in England and Wales will need to be satisfied that the proposed reduction of the share premium account will not adversely impact on the ability of the Company to discharge the claims of its creditors. The Company anticipates being able to do so. The reduction of the share premium account will not be effective until the order of the High Court of Justice in England and Wales confirming the reduction has been registered with the registrar of companies. Such reduction will not alter the number of Ordinary Shares in issue, nor the rights attaching to such Ordinary Shares

The Board confirms that, in its opinion, all of the resolutions are in the best interests of the Shareholders of the Company as a whole and unanimously recommends that Shareholders vote in favour of them.

• 1. Voting on all Resolutions will be conducted by way of a poll rather than a show of hands. In a poll, each Shareholder has one vote for every share held. This is a more transparent method of voting as Shareholders' votes are counted according to the number of shares registered in their names. On arrival at the AGM all those entitled to vote will be required to register and collect a poll card. It is advisable to have some form of identification with you as you may be asked to provide evidence of your identity to the Company's registrar, Computershare Investor Services PLC (Registrar), prior to being admitted to the AGM. As soon as practicable following the meeting, the results of the voting will be announced via a regulatory information service and also placed on the Company's website.
• 1. Only those Shareholders registered in the Company's register of members at:
• (a) 18:00 p.m. on Tuesday 24 May 2022; or
• (b) if this meeting is adjourned, at 18:00 p.m. on the day two days prior to the adjourned meeting,

shall be entitled to vote at the meeting. Changes to the register of members after the relevant deadline shall be disregarded in determining the rights of any person to vote at the meeting.

• 1. Every member entitled to attend and vote at the AGM 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. A proxy need not be a member of the Company but must attend the meeting for the member's vote to be counted. A member may appoint more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that member. However in the circumstances of the closed meeting, only the Chairman would be able to act as your proxy for the purpose of casting your vote in this AGM.
• 1. A Form of Proxy is provided with this Notice. Amended instructions must also be received by the Registrar by the deadline for receipt of Forms of Proxy.
• 1. If the Chairman of the AGM, as your proxy, is being appointed in relation to less than your full voting entitlement, please enter in the box next to the Chairman's name the number of Ordinary Shares in relation to which they are authorised to act as your proxy. If left blank the Chairman 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).
• 1. In the case of joint holders, where more than one of the joint holders completes a proxy appointment, only the appointment submitted by the most senior holder will be accepted. Seniority is determined by the order in which the names 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).
• 1. To be effective, the Form of Proxy and any power of attorney or other authority under which it is signed (or a notarially certified copy of such authority) must be deposited with the Company's registrars, by post to: Computershare Investor Services plc, The Pavilions, Bridgwater Road, Bristol BS99 6ZY; or by hand to: Computershare Investor Services plc, The Pavilions, Bridgwater Road, Bristol BS99 6ZY, not less than 48 hours before the time appointed for the AGM or any adjourned AGM.
• 1. As an alternative to appointing a proxy using the Form of Proxy (or CREST under Notes 13-16 below), members can appoint a proxy online at: www.investorcentre.co.uk/eproxy. In order to appoint a proxy using this website, members will need their Control Number, Shareholder Reference Number and PIN. This information is printed on the Form of Proxy. If for any reason a member does not have this information, they will need to contact the Registrar by telephone on +44 (0) 370 703 6242 or by logging on to www.investorcentre.co.uk/contactus.
• 1. To be effective, the electronic appointment of a proxy for the meeting and any power of attorney or other authority under which the proxy appointment is made must be received by the Company's registrars not less than 48 hours before the time appointed for the AGM

or any adjourned AGM or (in the case of a poll taken otherwise than at or on the same day as the meeting or adjourned meeting) for the taking of the poll at which it is to be used.

• 1. Any person receiving a copy of this Notice as a person nominated by a member to enjoy information rights under section 146 of the Act (a Nominated Person) should note that the provisions in this Notice concerning the appointment of a proxy to attend the meeting in place of a member, do not apply to a Nominated Person as only Shareholders have the right to appoint a proxy. However, a Nominated Person may have a right under an agreement between the Nominated Person and the member by whom he or she was nominated to be appointed, or to have someone else appointed, as a proxy for the 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 at the meeting.
• 1. Pursuant to regulation 41(1) of the Uncertificated Securities Regulations 2001 (2001 No. 3755) (as amended) and for the purposes of section 360B of the Act, the Company has specified that only those members registered on the register of members of the Company at 18:00 p.m. on Tuesday 24 May 2022 or if the meeting is adjourned, on the day which is two days prior to the time of the adjourned meeting shall be entitled to attend and vote at the AGM in respect of the number of Ordinary Shares registered in their name at that time. Changes to the register of members after 18:00 p.m. on Tuesday 24 May 2022 shall be disregarded in determining the rights of any person to attend and vote at the AGM.
• 1. CREST members who wish to appoint the Chairman as their proxy through the CREST electronic proxy appointment service may do so for the AGM to be held on Thursday 26 May 2022 and any adjournment(s) thereof by using the procedures described in the CREST Manual (available via www.euroclear.com/CREST). 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.
• 1. In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (CREST Proxy Instruction) must be properly authenticated in accordance with Euroclear UK & Ireland Limited's specifications and must contain the information required for such instructions, as described in the CREST Manual (available via www.euroclear.com/CREST). 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 Registrar (ID number 3RA50) by the latest time(s) for receipt of proxy appointments, together with any power of attorney or other authority under which it is sent. 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 Registrar 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.
• 1. CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear UK & Ireland Limited 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 (www.euroclear.com/CREST).
• 1. 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 (as amended). For further information relating to the CREST proxy system, please refer to the CREST Manual.
• 1. A 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, in the case of multiple corporate representatives of the same corporate shareholder, they are appointed in respect of different shares owned by the corporate shareholder or, if they are appointed in respect of those same shares, they vote those shares in the same way). Corporate shareholders can also appoint a proxy in accordance with Notes 3-10 and, if relevant, Note 11 above. Please note, however, that if multiple corporate representatives purport to vote the same block of shares in different ways, they will be treated as not having voted.
• 1. Shareholders may change proxy instructions by submitting a new proxy appointment using the methods set out above. Note that the cutoff 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.

If you submit more than one valid proxy appointment, the appointment received last before the latest time for the receipt of proxies will take precedence.

• 1. If the Chairman, as a result of any proxy appointments, is given discretion as to how the votes the subject of those proxies are cast and the voting rights in respect of those discretionary proxies, when added to the interests in the Company's securities already held by the Chairman, result in the Chairman holding such number of voting rights that he has a notifiable obligation under the Disclosure Guidance and Transparency Rules, the Chairman will make the necessary notifications to the Company and the Financial Conduct Authority. As a result, any member holding 3% or more of the voting rights in the Company who grants the Chairman a discretionary proxy in respect of some or all of those voting rights and so would otherwise have a notification obligation under the Disclosure Guidance and Transparency Rules, need not make a separate notification to the Company and the Financial Conduct Authority.
• 1. Any Shareholder attending the AGM has the right to ask questions before the date of the AGM by written or electronic means. The Company must cause to be answered any such question relating to the business being dealt with at the meeting put by a Shareholder and

shall publish its answers as soon as reasonably practicable after the AGM on its website at http://www.energean.com. However, members should note that no answer need be given in the following circumstances:

• (i) if to do so would interfere unduly with the preparation of the AGM or would involve a disclosure of confidential information;
• (ii) if the answer has already been given on a website in the form of an answer to a question; or
• (iii) if it is undesirable in the interests of the Company or the good order of the AGM that the question be answered.
• 1. As at 27 April 2022, being the latest practicable date before the publication of this Notice, the Company's issued capital consisted of 178,040,505 Ordinary Shares carrying one vote each. Therefore, the total voting rights in the Company as at 27 April 2022 are 178,040,505 Ordinary Shares.
• 1. This Notice, together with information about the total numbers of shares in the Company in respect of which members are entitled to exercise voting rights at the meeting as at 27 April 2022, being the latest practicable date before the publication of this Notice, and, if applicable, any members' matters of business received after the publication of this Notice can be found on the Company's website at http://www.energean.com
• 1. Shareholders are advised that, unless otherwise stated, any telephone number, website and email address set out in this Notice, the Form of Proxy, or Chairman's letter should not be used to communicate with the Company (including the service of documents or information relating to the proceedings at the AGM). Shareholders who have general queries about the meeting should email cosec@energean.com (no other methods of communication will be accepted).
• 1. Under section 527 of the Act, Shareholders 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 auditors' report and the conduct of the audit) that are to be laid before the AGM; or (ii) any circumstances 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. The Company may not require the Shareholders 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 auditors not later than the time when it makes the statement available on the website. The business which may be dealt with at the AGM includes any statement that the Company has been required under section 527 of the Act to publish on a website.
• 1. A Shareholder wishing to request publication of a statement under note 24 above must send the request to the Company using one of the following methods:
• 25.1 by email to cosec@energean.com and to be confirmed in writing to the registered office address; or
• 25.2 by fax to +44 203 755 7299 marked for the attention of Eleftheria Kotsana and confirmed in writing to the registered office address.
• 1. Copies of service contracts of the executive directors and non-executive directors' contracts for services are available upon request from the Company Secretary.
