Recommended and Increased Cash Offer for Arawak Energy Limited by ROSCO S.A. (a member of the Vitol Group)

GENEVA--(Marketwire - March 10, 2009) - Rosco S.A. ("Rosco") announced yesterday, 9 March 2009, that its Offer for Arawak Energy Limited is extended and will remain open for acceptance until 3.00 p.m. London time (11.00 a.m. Ontario time) on 24 March 2009, unless otherwise extended, and Rosco will not declare that the Offer is wholly unconditional and will not take up any Arawak Shares tendered prior to that time.

Acceptance Levels

As at 5.00 p.m. London time (1.00 p.m. Ontario time) on 9 March 2009, Rosco had received valid acceptances of the Offer in respect of a total of 88,626,925 Arawak Shares representing approximately 48.52 per cent. of the issued common share capital of Arawak and approximately 82.84 per cent. of the Arawak Shares to which the Offer relates.

The Arawak Shares currently held by Rosco or persons acting in concert with Rosco together with the Arawak Shares in respect of which valid acceptances of the Offer have been received represent in aggregate approximately 89.95 per cent. of the issued common share capital of Arawak.

The level of acceptances of the Offer referred to above includes acceptances received pursuant to irrevocable undertakings entered into by the Arawak Directors and Mancal Corporation (a company associated with one of the Arawak Directors) in respect of 9,285,776 Arawak Shares, being their entire holdings of Arawak Shares and representing approximately 5.08 per cent. of the issued common share capital of Arawak.

None of the acceptances of the Offer referred to above were received from persons acting in concert with Rosco.

All Arawak Shares in respect of which a valid acceptance of the Offer has been received may be counted towards satisfaction of the acceptance condition (being more than 50 per cent. of the voting rights then normally exercisable at a general meeting of Arawak) to which the Offer is subject. However, due to the conflicting regulatory regimes of Canada and the United Kingdom, with the consent of the Panel and the OSC, valid acceptances received by Rosco prior to the satisfaction or waiver of all other Conditions, shall be deemed not to have been received for the purposes of determining if the acceptance condition (as defined in Section B of Part 3 of the Offer Document) has been satisfied, until such time as Rosco declares that the Offer has become wholly unconditional and that it will take-up the Arawak shares tendered.

Save as referred to in this announcement or in the offer document dated 30 January 2009 ("Offer Document") containing the full terms and conditions of the Offer, neither Rosco nor any person acting in concert with Rosco, had an interest in or a right to subscribe for relevant securities of Arawak or had any short position (whether conditional or absolute and whether in the money or otherwise), including any short position under a derivative, any agreement to sell or any delivery obligation or right to require another person to purchase or take delivery of any relevant securities of Arawak and neither Rosco nor any person acting in concert with Rosco had borrowed or lent relevant securities of Arawak.

Compulsory Acquisition and Delisting

As stated in paragraph 10 of Part 2 of the Offer Document, if the Offer becomes or is declared unconditional in all respects and Rosco receives sufficient acceptances under the Offer, it will be Rosco's intention, subject to receipt of applicable consents (if any), to (i) if Rosco acquires at least 90 per cent. of the Arawak Shares to which the Offer relates, exercise its rights pursuant to the provisions of Articles 117 and 118 of the Companies Law to acquire compulsorily the remaining Arawak Shares to which the Offer relates (construed in accordance with Part 18 of the Companies Law); (ii) procure that Arawak makes application to the Toronto Stock Exchange for the de-listing of Arawak Shares from such exchange; and (iii) procure that Arawak makes applications to the UK Listing Authority for the cancellation of listing of Arawak Shares on the Official List and to the London Stock Exchange for the cancellation of admission to trading in Arawak Shares on its market for listed securities.

De-listing from the London Stock Exchange and the Toronto Stock Exchange would significantly reduce the liquidity and marketability of any Arawak Shares not tendered to the Offer, and could also result in adverse tax consequences to Canadian Resident Holders as further described in sub-paragraph 15(a)(iv) of Part 2 of the Offer Document. In addition, if the Arawak Shares are de-listed from the Official List of the London Stock Exchange, the Relationship Agreement between Arawak, Rosco and Vitol B.V. would terminate, removing the protections afforded under that agreement.

Capitalised terms used and not defined in this announcement have the same meanings given to them in the Offer Document.

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 per cent or more of any class of "relevant securities" of Arawak, all "dealings" in any "relevant securities" of Arawak (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 p.m. (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 Arawak, 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 Arawak by Rosco or Arawak, or by 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 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.

Not for release, publication or distribution in whole or in part, in or into or from Australia or Japan or any other jurisdiction where to do so would constitute a violation of the relevant laws of such jurisdiction.
