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 holder's name (see reverse) the number of shares in relation to which they are authorised to act as your proxy. If returned without an indication as to how the proxy shall vote on any particular matter, the proxy will exercise his discretion as to whether, and if so how, he votes (or if this proxy form has been issued in respect of a designated account for a shareholder, the proxy will exercise his discretion as to whether, and if so how, he votes).
• 2. To appoint more than one proxy, an additional proxy form(s) may be obtained by contacting the Registrar's helpline on +44 (0) 370 703 6242 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.

Kindly Note: This form is issued only to the addressee(s) and is specific to the unique designated account printed hereon. This personalised form is not transferable between different: (i) account holders; or (ii) uniquely designated accounts. The Company and Computershare Investor Services PLC accept no liability for any instruction that does not comply with these conditions.

• 4. Pursuant to Regulation 41 of the Uncertifi cated 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.
• 5. To appoint one or more proxies or to give an instruction to a proxy (whether previously appointed or otherwise) via a designated voting platform, any such messages must be received by the issuer's agent prior to the specifi ed deadline within the relevant system. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp generated by the relevant designated voting platform) from which the issuer's agent is able to retrieve the message. The Company may treat as invalid a proxy appointment sent via a designated voting platform in the circumstances set out in Regulation 35(5)(a) of the Uncertifi cated Securities Regulations 2001.

All Named Holders

In light of the social distancing measures aimed at reducing the transmission of the COVID-19 virus in the United Kingdom, please note that attendance at the Annual General Meeting in person is not possible. The Annual General Meeting will be a closed meeting. Shareholders should not attempt to attend the Annual General Meeting in person. Any shareholders who attempt to attend in person will be refused entry. Shareholders should instead vote in advance by appointing the Chair of the Annual General Meeting as their proxy in respect of all of their shares to vote on their behalf. Due to the restrictions on physical attendance at the Annual General Meeting, any other individual(s) will not be able to attend, speak or vote on their behalf.

Continued shareholder engagement remains very important to the Company and shareholders will therefore be able to listen to the live audio-cast of the Annual General Meeting and submit questions remotely throughout.

Shareholders may also submit questions in advance via ir@tullowoil.com

Detailed instructions about voting by proxy and accessing the audio-cast are set out in the Notice of Meeting.
