Delivery of EnQuest Shares to Petrofac Shareholders

26 March 2010

Petrofac Limited ("Petrofac" or the "Company")

Further to the circular sent to Petrofac Shareholders on 4 March 2010 (the "Circular), to enable Petrofac to deliver the EnQuest Shares following the completion of the Demerger, each Petrofac Shareholder is required to identify the number of Petrofac Shares held by or on behalf of a person who either (a) is located outside of the United States of America or (b) has made the requested QIB Confirmations.

In order to achieve this:

* if a Petrofac Shareholder holds their Petrofac Shares in certificated form they must return the Eligible Share Form, which was enclosed with the Circular, to Capita Registrars, Corporate Actions, The Registry, 34 Beckenham Road, Beckenham, Kent BR3 4TU, to be received no later than 3.00 p.m. on 1 April 2010. If you require an Eligible Share Form please contact the Shareholder Helpline on 0871 664 0321 (from inside the United Kingdom) or +44 20 8639 3399 (from outside the United Kingdom).

* if a Petrofac shareholder holds their Petrofac Shares in uncertificated form, they must transfer their Eligible Shares to the appropriate escrow balances (that is send a TTE Instruction) specifying Capita Registrars as the Escrow Agent as soon as possible and in any event so that the TTE Instruction settles no later than 3.00 p.m. on 1 April 2010.

To the extent that any Petrofac Shareholders do not establish to the satisfaction of the Company that their Petrofac Shares are held by or on behalf of a person who either (a) is located outside the United States or (b) has made the QIB Confirmations, such Petrofac Shares may, at the absolute discretion of Petrofac, be deemed to be ''Ineligible Shares" in respect of which the Company has received an instruction to procure purchasers on their behalf for the EnQuest Shares relating to such Ineligible Shares with the net proceeds remitted to such Petrofac Shareholders.

It should be noted that in the event that any Petrofac Shares are deemed to be Ineligible Shares, Petrofac does not currently intend to procure purchasers for the corresponding EnQuest Shares immediately after London Admission. For a short period of time following London Admission, Petrofac expects to continue to seek the requisite representations, warranties, and confirmations in respect of any Petrofac Shares deemed to be Ineligible Shares in order to enable the release, where possible, of the corresponding EnQuest Shares to the relevant Petrofac Shareholder. That notwithstanding, Petrofac reserves all rights set out in the Circular and its Articles to exercise its discretion as to the treatment of Ineligible Shares.

Full details of the procedures above are set out in paragraph 8 of part VI of the Circular.

All defined terms in this announcement are as per the Circular.
