Recommended Cash Offer by Emirates National Oil Company Ltd. For the Shares in Dragon Oil plc Not Already Owned by ENOC

Delisting

On 2 August 2015, ENOC announced a revision to the original Offer price to 800 pence in cash for each Dragon Oil Share, declared the Offer unconditional in all respects and stated that it intended to procure the delisting of Dragon Oil shortly. The document containing the full terms of, and conditions to, the original Offer was posted by ENOC to Dragon Oil Shareholders on 1 July 2015 (the “Offer Document”). Capitalised terms used but not otherwise defined in this announcement have the meanings set out in the Offer Document.

As at 3.00 p.m. (Dublin time) on 6 August 2015, ENOC had received acceptances of the Offer valid in all respects relating to 118,391,861 Dragon Oil Shares, representing (i) approximately 24.0 per cent. of the current issued share capital of Dragon Oil and (ii) approximately 51.5 per cent. of the voting rights held by the Independent Shareholders on the date of the Rule 2.5 Announcement.

Accordingly, the relevant thresholds have been met under the Listing Rules and the listing rules of the Irish Stock Exchange to effect delisting and ENOC has requested and directed Dragon Oil to commence the delisting process of Dragon Oil immediately. Pursuant to the Listing Rules and the listing rules of the Irish Stock Exchange, Dragon Oil announces that the delisting notice period has now commenced and it is anticipated that delisting will take effect from 8:00 a.m. (Dublin time) on 7 September 2015.  Consequently, the last day of trading of Dragon Oil Shares on the Irish Stock Exchange and London Stock Exchange would be 4 September 2015.

The cancellation of trading of Dragon Oil Shares will significantly reduce the liquidity and marketability of any Dragon Oil Shares not acquired by ENOC.

Intended Acceptances

As at 3.00 p.m. (Dublin time) on 6 August 2015, ENOC had also received intended acceptances of the Offer relating to 47,420,042 Dragon Oil Shares, representing approximately 9.6 per cent. of the current issued share capital of Dragon Oil.
