Acceptances

BowLeven Plc 15 January 2007 Not for release, publication or distribution, in whole or in part, in or into or from the United States, Canada, Australia or Japan 15 January 2007 Recommended Offer by BowLeven plc ('BowLeven') for FirstAfrica Oil plc ('FirstAfrica') Offer Unconditional as to Acceptances As at 3.00pm on 12 January 2007, valid acceptances had been received in respect of 2,371,314,068 FirstAfrica Shares (representing approximately 88.62 per cent. of FirstAfrica's existing issued share capital). Prior to the posting of the Offer Document, BowLeven had received irrevocable undertakings from the FirstAfrica Directors that own FirstAfrica Shares and certain other FirstAfrica Shareholders to accept the Offer in respect of, in aggregate, 776,935,971 FirstAfrica Shares representing approximately 29.04 per cent. of the existing issued FirstAfrica Shares. Of these irrevocable undertakings BowLeven has received valid acceptances from, in aggregate, 776,885,971 FirstAfrica Shares, representing approximately 29.03 per cent. of the existing issued FirstAfrica Shares. Mr Robert Rainey, one of the FirstAfrica Directors that provided an irrevocable undertaking prior to posting of the Offer Document in respect of 50,000 FirstAfrica Shares, representing approximately 0.0019 per cent. of the existing issued FirstAfrica Shares, has indicated that he has accepted the Offer but the Receiving Agent has not, as at the date of this announcement, been able to confirm acceptance with respect to these FirstAfrica Shares. On 3 August 2006, Mr Jerry Anthony, then a director of BowLeven, purchased 24,280 FirstAfrica Shares representing approximately 0.0009 per cent. of the existing issued FirstAfrica Shares. Mr Jerry Anthony died on 30 December 2006. Acceptances for these FirstAfrica Shares have not been received. The BowLeven Board announces that it is lowering its valid acceptance condition from 90 per cent. to 50 per cent. of the FirstAfrica Shares to which the Offer relates. Accordingly, the BowLeven Board also announces that the Offer made by Jefferies International Limited on behalf of BowLeven plc for FirstAfrica Oil plc has been declared unconditional as to acceptances. The Offer remains open for acceptance until further notice. Until such time as Jefferies International Limited declares the Offer wholly unconditional, the Offer remains subject to all the other conditions as set out in the Offer Document dated 22 December 2006. Terms defined in the Offer Document dated 22 December 2006 have the same meaning in this announcement, except that the BowLeven Board now no longer includes Mr Jerry Anthony.

Dealing Disclosure Requirements Under the provisions of Rule 8.3 of the Code, if any person is, or becomes, 'interested' (directly or indirectly) in 1% or more of any class of 'relevant securities' of BowLeven or of FirstAfrica, all 'dealings' in any 'relevant securities' of that company (including by means of an option in respect of, or a derivative referenced to, any such 'relevant securities') must be publicly disclosed by no later than 3.30 pm (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the 'offer period' otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an 'interest' in 'relevant securities' of BowLeven or of FirstAfrica, they will be deemed to be a single person for the purpose of Rule 8.3. Under the provisions of Rule 8.1 of the Code, all 'dealings' in 'relevant securities' of BowLeven or of FirstAfrica or any of their respective 'associates', must be disclosed by no later than 12.00 noon (London time) on the London business day following the date of the relevant transaction. A disclosure table, giving details of the companies in whose 'relevant securities' 'dealings' should be disclosed, and the number of such securities in issue, can be found on the Takeover Panel's website at www.thetakeoverpanel.org.uk . 'Interests in securities' arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In particular, a person will be treated as having an 'interest' by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities. Terms in quotation marks are defined in the Code, which can also be found on the Panel's website. If you are in any doubt as to whether or not you are required to disclose a 'dealing' under Rule 8, you should consult the Panel.
