    Recommended offer for medOil plc declared unconditional in all respects

On 7 September 2007, Capricorn Petroleum Limited (a subsidiary of Cairn Energy
PLC) ('Capricorn') announced the terms of a recommended cash offer to be made by
Jefferies on behalf of Capricorn for the entire issued and to be issued share
capital of medOil plc ('medOil') at a price of 23 pence per medOil Share. The
Offer Document containing details of the Offer was posted to medOil Shareholders
on 18 September 2007.

The Board of Capricorn is pleased to announce that all conditions of the Offer
have now been satisfied or waived and that the Offer is declared unconditional
in all respects. Total valid acceptances, together with medOil Shares otherwise
acquired by Capricorn, represent in aggregate, approximately 93.0 per cent. of
the existing share capital of medOil. The Offer remains open for acceptance
until further notice.

Level of Acceptances

The Board of Capricorn announces that, as at 1.00 p.m. on 9 October 2007 (being
the first closing date of the Offer), valid acceptances of the Offer had been
received in respect of a total of 42,342,000 medOil Shares, which, together with
a further 250,000 medOil Shares acquired by Capricorn since 18 September 2007,
represent approximately 91.8 per cent. of the medOil Shares to which the Offer
relates.

The total of acceptances includes valid acceptances of the Offer received in
respect of, in aggregate, 25,587,778 medOil Shares, representing approximately
47.2 per cent. of the existing issued share capital of medOil, and being all of
the medOil Shares in respect of which irrevocable undertakings and letters of
intent to accept the Offer had been received as at 7 September 2007.

Share purchases and irrevocable undertakings to accept the Offer

As at 17 September 2007 (being the latest practicable date prior to the posting
of the Offer Document), Capricorn had acquired 7,869,000 medOil Shares,
representing approximately 14.5 per cent of the existing issued share capital of
medOil (taking into account an additional 200,000 shares issued since 17
September 2007). Capricorn subsequently acquired 250,000 medOil Shares,
representing approximately 0.5 per cent. of the issued share capital of medOil.
Accordingly, Capricorn has acquired, in aggregate, 8,119,000 medOil Shares,
representing approximately 15.0 per cent. of the existing issued share capital
of medOil.

As at 17 September 2007 (being the latest practicable date prior to the posting
of the Offer Document), Capricorn had received irrevocable undertakings from the
medOil Directors that own medOil Shares and certain other medOil Shareholders to
accept the Offer in respect of, in aggregate, 19,180,000 medOil Shares,
representing approximately 35.4 per cent. of the existing issued share capital
of medOil.

In addition, as at 17 September 2007 (being the latest practicable date prior to
the posting of the Offer Document), Capricorn had also received non-binding
letters of intent from medOil Shareholders to accept the Offer in respect of, in
aggregate, 6,407,778 medOil Shares, representing approximately 11.8 per cent. of
the existing issued  share capital of medOil.

Save as disclosed herein, no medOil Shares have been acquired or agreed to be
acquired by or on behalf of Capricorn or any person acting in concert with
Capricorn during the Offer Period and neither Capricorn nor any person acting in
concert with Capricorn has the benefit of any irrevocable commitment or letter
of intent in respect of any medOil Shares or has any interest in any medOil
Shares, or any short position (whether conditional or absolute and whether in
the money or otherwise and including any short position under a derivative), any
agreement to sell, any delivery obligation, any right to require another person
to purchase or take delivery in respect of any medOil Shares, any right to
subscribe for any medOil Shares or any stock borrowing or lending arrangement in
respect of any medOil Shares.

Settlement of consideration

Settlement of cash consideration due under the Offer will be dispatched (or, in
the case of medOil Shareholders holding medOil shares in uncertificated form,
will be credited through CREST), within 14 days in respect of medOil Shares for
which acceptances of the Offer, valid in all respects, have already been
received.

De-listing and compulsory acquisition of medOil Shares

As Capricorn has received acceptances under the Offer in respect of 90 per cent.
or more both of the nominal value of the medOil Shares to which the Offer
relates and of the voting rights carried by such medOil Shares, Capricorn will
as soon as practicable give notice to those medOil Shareholders who have not
accepted the Offer informing them that it will compulsorily acquire their medOil
Shares pursuant to its rights under the provisions of Sections 979 to 982
(inclusive) of the Companies Act 2006.

Further to the Offer being declared unconditional in all respects, Capricorn
will now procure that medOil applies, as soon as practicable, to the London
Stock Exchange for the cancellation of the admission to trading of medOil shares
on AIM. Delisting will significantly reduce the liquidity and marketability of
any medOil Shares not acquired under the Offer at that time.

Following the cancellation of the admission to trading of medOil's Shares on
AIM, medOil may be re-registered as a private company in due course.

Further acceptances

medOil Shareholders who wish to accept the Offer, but have not yet done so, are
strongly encouraged to complete and return a Form of Acceptance in accordance
with the instructions set out in the Offer Document. If medOil Shares are held
in CREST, acceptance should be made electronically so that the TTE instruction
settles as soon as possible.

Terms defined in the Offer Document dated 18 September 2007 have the same
meaning in this announcement.
