Boiler Room Scams

Tullow Oil plc has become aware that their shareholders have received unsolicited correspondence/contact concerning investment matters. These are typically from overseas based ‘brokers’ who target UK shareholders offering to sell them what often turns to be worthless or high risk shares in US or UK investments. Shareholders are advised to be cautious about any unsolicited financial advice, offers to buy shares at a discount or offers of free company reports.

What to do if you have been contacted in this manner:

• Ensure you get the full name of the person you spoke to and the organisation they represent;
• Check they are properly authorized by the Financial Services Authority (FSA) before going any further. You can check this at www.fsa.gov.uk/register;
• The FSA website maintains a list of overseas firms who have targeted or are targeting UK investors, and any approach(es) from these organisations should be reported to the FSA so the list can be kept up to date, and appropriate action considered.
• Inform our registrars, Computershare Investor Services plc by calling 0870 703 6242 for UK callers, 01 216 3744 for Irish Investors or 0044 870 7036242 for Overseas callers. Alternatively e-mail webqueries@computershare.co.uk

Shareholder Fraud: Protection of your Investment

To reduce the risk of becoming a victim of fraud you can follow the advice as below:

• Ensure all share certificates are stored in a safe place, or hold your shares electronically in CREST via a nominee;
• Keep all correspondence from the Registrars which shows a shareholder investor code in a safe place, or destroy correspondence by shredding;
• When changing address, inform the Registrars. If a letter from the Registrars is received regarding a change of address and there has been no recent move, contact the Registrars immediately. The shareholder concerned may be a victim of identity theft;
• Know when the Company is paying its dividend. Shareholders may wish to have their dividends paid directly into their bank or building society account, both for the convenience and resulting reduction in the risk of the cheque being intercepted or lost in the post. It is advisable to inform the Company Registrar about any changes to bank or building society details and shareholders should respond to any letters the Registrar sends them regarding this.
• When buying or selling shares, shareholders should seek to only deal with brokers registered in their own country of residence or the UK.
