Computershare online enquiry service

Computershare provides a range of services through its online portal, Investor Centre, which can be accessed free of charge at www.investorcentre.co.uk. This service, accessible from anywhere in the world, enables shareholders to check details of their shareholdings or dividends, download forms to notify changes in personal details, and access other relevant information.

Payment of dividends

Shareholders can have their dividends paid directly into a UK sterling or Irish euro bank account and have the tax voucher sent directly to their registered address. You can register your account details in Investor Centre or, alternatively, download a dividend mandate form.

Overseas shareholders who wish to have their dividends paid in a local currency can use the Global Payments Service that Computershare has established. Details of the service can be accessed in the Shareholder Services section of the Investors area of the Tullow website: www.tullowoil.com.

Electronic communication

Shareholders have the option to receive shareholder communications including annual reports and notices of meetings electronically. Tullow actively supports Woodland Trust, the UK’s leading woodland conservation charity. Computershare, together with Woodland Trust, has established eTree, an environmental programme designed to promote electronic shareholder communications. Under this programme, the Company makes a donation to eTree for every shareholder who registers for electronic communication. To register for this service, simply visit www.etreeuk.com/tullowoilplc with your shareholder number and email address to hand. Once registered, shareholders will be emailed when an annual report or notice of meeting is available for viewing on the Tullow website.

Shareholder security

Shareholders are advised to be cautious about any unsolicited financial advice; offers to buy shares at a discount or offers of free company reports. More detailed information can be found at www.moneymadeclear.fsa.gov.uk and in the Shareholder Services section of the Investors area of the Tullow website: www.tullowoil.com.

ShareGift

If you have a small number of shares whose value makes it uneconomical to sell you may wish to consider donating them to ShareGift. Any shares donated to ShareGift will be aggregated and sold when possible with the proceeds donated to a wide range of UK charities. The relevant share transfer form may be obtained from Computershare. Further information about the scheme is available at www.ShareGift.org.
