Petroceltic International plc

Result of Placing - US$60 million (£37 million) raised

Petroceltic International plc ("Petroceltic"), is pleased to announce the completion of the equity placing announced yesterday afternoon (the "Placing"). A total of 351,000,000 new Ordinary Shares of the Company (the "Placing Shares") have been conditionally placed by Merrill Lynch International ("BofA Merrill Lynch"), J&E Davy ("Davy") and Mirabaud Securities LLP ("Mirabaud") acting as joint bookrunners (the "Joint Bookrunners") in relation to the Placing at a price of 10.5 pence each, to raise approximately US$60 million (£37 million) before commissions and expenses.

The Placing Shares equal, in number, approximately 17 per cent. of the Ordinary Shares in issue immediately before the Placing. The Placing Shares will be issued credited as fully paid and will rank pari passu with the existing Ordinary Shares.

Certain directors of Petroceltic will subscribe for the following Placing Shares:

The Company will apply for admission of the Placing Shares to be traded on the AIM market of the London Stock Exchange and the Enterprise Securities Market of the Irish Stock Exchange ("Admission"). It is expected that Admission will take place and that trading will commence on or around 13 June 2011.

The Placing is conditional upon, inter alia, Admission becoming effective and upon the passing of the Resolution at the Company's Extraordinary General Meeting proposed to be convened for on or around 10 June 2011. The Placing is also conditional on the Placing Agreement between the Company and the Joint Bookrunners becoming unconditional and not being terminated in accordance with its terms. It is anticipated that the settlement date will be on or around 13 June 2011.

Following Admission, Petroceltic's issued share capital will consist of 2,365,355,049 Ordinary Shares of €0.0125c each. On a poll, each Ordinary Share confers one vote and therefore the total number of Ordinary Shares in Petroceltic to which voting rights are attached on the basis of one vote per Ordinary Share held will be 2,365,355,049 on completion of the Placing. The above total voting rights figure of 2,365,355,049 may be used by shareholders as the denominator for the calculations by which they can determine whether they are required to notify their interests in, or a change to their interest in, the Company under the Irish Companies Act 1990 and the ESM Rules for Companies.

Capitalised terms used, but not defined in this announcement have the same meanings as set out in the announcement released by the Company earlier today in relation to the Placing.
