Summary:



•          The Boards of Cairn and medOil are pleased to announce that they have
today reached agreement on the terms of a recommended cash offer to be made by
Jefferies International on behalf of Capricorn for the whole of the issued and
to be issued share capital of medOil.



•          Under the terms of the Offer, medOil Shareholders will be entitled to
receive 23 pence per medOil Share in cash. On this basis, the terms of the Offer
value the entire existing issued and to be issued share capital of medOil at
approximately £14.9 million.



•          The Offer Price represents a premium of:



-         approximately 19.5 per cent. to the Closing Price of 19.25 pence per
medOil Share on 6 September 2007 (being the last Business Day prior to this
announcement); and

-         approximately 19.8 per cent. to the average Closing Price of 19.2
pence per medOil Share for the 30 calendar days ended 6 September 2007 (being
the last Business Day prior to this announcement).



•          The medOil Directors have agreed unanimously to recommend that medOil
Shareholders accept the Offer, when made, as each of the medOil Directors has
irrevocably undertaken to do (or procure to be done) once the Offer has been
made in respect of his own beneficial holding of medOil Shares (amounting, in
aggregate to 13,346,667 medOil Shares, representing approximately 24.7 per cent.
of the existing issued share capital of medOil). In addition, those of the
medOil Directors who hold medOil Warrants and one other holder of medOil
Warrants have undertaken, conditional upon the Offer becoming or being declared
unconditional in all respects, to surrender the medOil Warrants held by them
(which entitle them to subscribe for an aggregate of 10,600,000 medOil Shares)
in exchange for a cash cancellation payment per medOil Warrant based upon the
Offer Price, from Capricorn.



•          Capricorn has also received an irrevocable undertaking to accept the
Offer from one other medOil shareholder, in respect of 5,833,333 medOil Shares,
representing approximately 10.8 per cent. of the existing issued share capital
of medOil.



•          Accordingly, Capricorn has received irrevocable undertakings in
respect of, in aggregate, 19,180,000 medOil Shares, representing approximately
35.5 per cent. of medOil's existing issued share capital.



•          Capricorn has received non-binding letters of intent to accept the
Offer from Universities Superannuation Scheme in respect of 4,393,889 medOil
Shares representing approximately 8.1 per cent. of the existing issued share
capital of medOil and from Aerion Fund Management with respect to its
shareholding in medOil which Capricorn understands is 2,013,889 medOil Shares
representing approximately 3.7 per cent. of the existing issued share capital of
medOil.




Commenting on the Offer, Mike Watts, Exploration and New Business Director of
Cairn and Chief Executive Officer of Capricorn Energy, said:



 'Capricorn is making the Offer for medOil to establish a position in oil
exploration, offshore Tunisia.  medOil has a 100 per cent. interest in the Louza
Permit where four wells have been drilled, two in the 1970's, two in the 1990's,
which resulted in one discovery, one well with oil shows and two dry holes.
medOil has recently acquired high quality 3-D seismic over part of the block.'



John Lander, Chairman of medOil, said:



'The Offer provides medOil Shareholders with an opportunity to lock-in value at
an attractive premium to the market value at a time when markets are
experiencing considerable volatility. The offer from Cairn reflects the quality
of the medOil exploration portfolio.'

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% or more of any class of 'relevant
securities' of medOil, all 'dealings' in any 'relevant securities' of that
company (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 pm (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 medOil,
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 medOil or any of their respective 'associates', must be disclosed

'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.

1. Introduction



The Boards of Cairn and medOil are pleased to announce that they have today
reached agreement on the terms of a recommended cash offer to be made by
Jefferies International on behalf of Capricorn for the whole of the issued and
to be issued share capital of medOil. The medOil Directors have agreed
unanimously to recommend the Offer.





2. The Offer



The Offer, which will be subject to the conditions and further terms set out, or
referred to, in Appendix I to this Announcement and to be set out in the Offer
Document and (in the case of medOil Shares held in certificated form) in the
Form of Acceptance, will be made by Jefferies International on behalf of
Capricorn on the following basis:



                 for every medOil Share       23 pence in cash



The Offer values the entire existing issued and to be issued share capital of
medOil at approximately £14.9 million.



The Offer Price represents a premium of:



  • approximately 19.5 per cent. to the Closing Price of 19.25 pence per
    medOil Share on 6 September 2007 (being the last Business Day prior to this
    Announcement); and

application to extend those interests is pending.  A decision in respect of that

Capricorn has also received an irrevocable undertaking to accept the Offer from
one other medOil Shareholder, in respect of, 5,833,333 medOil Shares,

of medOil.



Accordingly, irrevocable undertakings to accept the Offer have been received by
Capricorn in respect of, in aggregate, 19,180,000 medOil Shares representing
approximately 35.5 per cent. of medOil's existing issued share capital.



In addition, those of the medOil Directors who hold medOil Warrants and one

becoming or being declared unconditional in all respects, to surrender the
medOil Warrants held by them to subscribe for an aggregate of 10,600,000 medOil
Shares in exchange for a cash cancellation payment from Capricorn.

Universities Superannuation Scheme in respect of 4,393,889 medOil Shares
representing approximately 8.1 per cent. of the existing issued share capital of
medOil and from Aerion Fund Management with respect to its shareholding in
medOil which Capricorn understands is 2,013,889 medOil Shares representing
approximately 3.7 per cent. of the existing issued share capital of medOil.



Further details of these irrevocable undertakings, including the circumstances
in which they cease to be binding, are set out in Appendix III to this
Announcement.



4. Background to and reasons for the Offer



In connection with the separate listing of Cairn India Limited in January 2007,
Cairn reorganised its remaining oil and gas interests in Capricorn Energy.
Capricorn Energy will apply its exploration skills and experience and capital
resources in acquiring and developing new acreage and interests where it sees
significant exploration potential.



Capricorn is attracted to medOil because it establishes a position in oil
exploration, offshore Tunisia, as well as early phase exploration positions in
Sicily, Spain and Albania.  Capricorn Energy believes it has the financial
resources and operating experience to create and add value to this portfolio and
the expertise to rationalise it where appropriate.



5. Information on Cairn/Capricorn



Cairn is an oil and gas exploration and production company listed on the main
market of the London Stock Exchange which has a market capitalisation of
approximately £2.3 billion. In recent years, Cairn's key area of focus has been
the Indian sub continent and the company built up a core strategic business in
the region. In January 2007, Cairn India Limited, the Indian division of the
group, was listed on the Bombay Stock Exchange and National Stock Exchange of
India. Cairn retains an approximate 69% interest in Cairn India Limited. Cairn
is now expanding its horizons beyond the Indian sub continent seeking new
opportunities where its capital, exploration and commercial skills and
experience can be best used to create further shareholder value.



For the financial year ended 31 December 2006, Cairn reported total revenue of
US$286 million, cash generated from operations of US$207 million and a loss
after tax of US$82 million. Cairn reported total assets of US$1,924 million as
at 31 December 2006. Cairn reported average daily production of 24,523 boepd on
an entitlement interest basis in 2006.



Capricorn is a UK incorporated company which is an indirect subsidiary of Cairn.
Capricorn is a direct subsidiary of Capricorn Energy which currently owns oil
and gas interests in Bangladesh, Nepal and Northern India.  To date, Capricorn
has engaged in no activities other than those incidental to its organisation and
the making of the Offer.



Cairn Energy has separately announced today:



a)                  a recommended offer for Plectrum Petroleum Plc, a company
which also has oil exploration acreage offshore Tunisia; and



b)                  the agreement by Dyas BV, a wholly owned subsidiary of SHV
Holdings NV, to acquire a 10 per cent. interest in Capricorn Energy for a cash
consideration of approximately US$90 million.



6. Information on medOil



medOil was incorporated on 2 September 2004. On 2 December 2004, medOil acquired
a 100 per cent. interest in its subsidiary medOil Resources Limited. medOil was
established to acquire high-quality oil and gas assets focussed on established
petroliferous basins of the Mediterranean - North Africa region. medOil has
subsequently acquired or is actively pursuing potential interests in Tunisia,
Sicily, Spain and Albania.



The principle asset of medOil is the Louza permit offshore of Tunisia which
includes the oil discovery at M'Sela-1.



In March 2006 medOil raised £3.25 million to continue its exploration strategy,
in particular to enhance the value of its existing prospects in Tunisia through
the successful acquisition of a high-quality 3D seismic data set.  This 3D work
programme has been completed and the results analysed. This facilitated an
upward revision of the potential aggregate oil reserves (Prospective Resources)
in two of the four identified prospects adjacent to the M'Sela-1 oil discovery.



7. Management and employees



Cairn has given assurances to the medOil Board that the existing employment
rights, including pension rights, of all employees of the medOil Group will be
fully safeguarded upon the Offer becoming or being declared unconditional in all
respects.



8. Recommendation of the medOil Board



The medOil Directors are recommending acceptance of the Offer from Capricorn for
the entire issued and to be issued share capital of medOil. The medOil Directors
recognise that the Offer represents an opportunity for all medOil Shareholders
to realise a premium to the current market price in cash. The medOil Directors
believe that the Offer, whilst falling at the lower end of their views on
valuation of the Company, is at a level that should be considered by all medOil
shareholders, taking into account the following:



  • as stated in the interim results for the six months ended 31 March 2007,
    the medOil Directors have been actively seeking a farm-in partner on
    medOil's Louza permit in Tunisia;
  • negotiations with a farm-in partner were progressing prior to receipt of
    this Offer and this farm-in agreement could, if consummated, have had the
    potential to create significant value for medOil shareholders;
  • it is likely, however, that even with the potential farm-in agreement, the
    future development of medOil's assets as an independent entity would have
    required additional capital. It is likely that this would have taken the
    form of an equity injection and in the current market conditions it is not
    certain that these funds could have been raised;
  • medOil is a small quoted AIM company, with little liquidity in its shares;
  • the Offer represents an immediate opportunity for medOil Shareholders to
    exit for cash, at a premium to the closing middle market price prior to the
    Offer at 6 September 2007;
  • certain large shareholders of medOil have expressed a desire to receive a
    cash offer for medOil and one has provided an irrevocable undertaking to
    Capricorn to accept the Offer, once made; and
  • by accepting the Offer, medOil shareholders will avoid the dealing costs
    of a sale of their shares and this may be of value to medOil shareholders
    with small holdings.



Following consideration of the above factors, the medOil Directors, having been
so advised by Arden Partners, consider the terms of the Offer to be fair and
reasonable.  In providing advice to the medOil Directors, Arden Partners has
taken into account the commercial assessments of the medOil Directors.



Accordingly, the medOil Directors have agreed unanimously to recommend all
medOil Shareholders to accept the Offer, once made, as each of the medOil
Directors has irrevocably undertaken to do (or procure to be done) in respect of
their own respective beneficial holdings of medOil Shares amounting, in
aggregate to 13,346,667 medOil Shares, representing approximately 24.7 per cent.
of the existing issued share capital medOil.



9. medOil Warrants



The Offer will be extended to any medOil Shares issued or unconditionally
allotted prior to the date on which the Offer closes as a result of holders of
medOil Warrants exercising their rights to subscribe for medOil Shares. In this
connection, those of the medOil Directors who hold medOil Warrants and one other
shareholder who holds medOil Warrants have undertaken, conditional upon the
Offer becoming or being declared unconditional in all respects, to surrender the
medOil Warrants held by them to subscribe for an aggregate of 10,600,000 medOil
Shares in exchange for a cash cancellation payment from Capricorn. The amount of
the cash cancellation payment per medOil Warrant is equal to the Offer Price
less the subscription price due on exercise of those medOil Warrants and, where
applicable, any PAYE and employee's national insurance contributions due.



To the extent that holders of medOil Warrants do not exercise their rights to
subscribe for medOil Shares, it is intended that appropriate proposals will be
made to holders of medOil Warrants.



10. Disclosure of interests in medOil



Save as disclosed above in respect of the irrevocable undertakings, neither
Cairn, nor Capricorn, nor any Cairn Director, nor any director of Capricorn, nor
so far as any Cairn Director or Capricorn or any director of Capricorn is aware
any person acting in concert with Capricorn, (i) has any interest in or right to
subscribe for any relevant securities of medOil; or (ii) has any short positions
in respect of any relevant securities of medOil (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 take delivery; or (iii) has borrowed or lent any relevant
securities of medOil.



11. Financing



The cash consideration payable by Capricorn under the Offer will be funded from
existing cash resources made available by Capricorn Energy.



Jefferies has confirmed that it is satisfied that the necessary financial
resources are available to Capricorn to enable it to satisfy in full the cash
consideration payable by Capricorn as a result of full acceptance of the Offer.



12. Further details of the Offer



The medOil Shares will be acquired under the Offer fully paid and free from all
liens, equities, charges, encumbrances and other interests and together with all
rights attaching to them after the date of the Offer, including the right to
receive all dividends (if any) declared, made or paid thereafter.



The Offer will be subject to the conditions and further terms set out in
Appendix I to this Announcement and to be set out in the Offer Document and (in
the case of medOil Shares held in certificated form) in the Form of Acceptance.



13. Compulsory acquisition and de-listing



Capricorn intends, assuming it becomes so entitled, to use the procedures set
out in Part 28 of the Companies Act 2006 to acquire compulsorily any remaining
medOil Shares following the Offer becoming or being declared unconditional in
all respects. When the Offer becomes or is declared unconditional in all
respects, Capricorn intends to procure the making of an application by medOil to
the London Stock Exchange for the cancellation of the admission to trading of
medOil Shares on AIM.  It is anticipated that cancellation of admission to
trading will take effect no earlier than 20 Business Days after the Offer
becomes or is declared unconditional in all respects. The cancellation of
admission to trading on AIM of medOil Shares will significantly reduce the
liquidity and marketability of any medOil Shares not assented to the Offer and
their value may be affected in consequence. It is also intended that, following
the Offer becoming or being declared unconditional in all respects, medOil will
be re-registered as a private company under the relevant provisions of the
Companies Act 1985.



14. medOil issued share capital



In accordance with Rule 2.10 of the City Code, medOil confirms that it has
54,055,556 medOil Shares in issue. The International Securities Identification
Number for medOil is GB00B04M7K05.



15. General



The Offer Document and (in the case of medOil Shares held in certificated form)
the Form of Acceptance will be posted to medOil Shareholders as soon as
practicable and, in any event, within 28 days of this Announcement, except
otherwise with the consent of the Panel, other than (with any dispensation
required from the Panel) to certain overseas medOil Shareholders.  The full
terms of and conditions to the Offer will be set out in the Offer Document and
(in the case of medOil Shares held in certificated form) Form of Acceptance.  In
deciding whether or not to accept the Offer, medOil Shareholders should rely
solely on the information contained in, and follow the procedures described in,
the Offer Document and (in the case of medOil Shares held in certificated form)
Form of Acceptance.



The bases and sources of certain financial information contained in this
Announcement are set out in Appendix II.  Appendix III contains certain details
in respect of irrevocable undertakings given to Capricorn.  Appendix IV contains
definitions of certain expressions used in this Announcement.

nominees, trustees and custodians) must not mail or otherwise forward,
distribute or send it in, into or from the United States, Canada, Australia or
Japan. Doing so may render invalid any purported acceptance of the Offer.
Notwithstanding the foregoing, Capricorn will retain the right to permit the
Offer to be accepted and any sale of securities pursuant to the Offer to be
completed if, in its sole discretion, it is satisfied that the transaction in
question can be undertaken in compliance with applicable law and regulation.



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% or more of any class of 'relevant
securities' of medOil, all 'dealings' in any 'relevant securities' of that
company (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 pm (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 medOil,
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 medOil or 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 Takeover 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.

                   Part B: Certain further terms of the Offer



The formal offer by Capricorn will be subject to the terms and conditions as set
out in this Appendix I and as will be set out in the Offer Document and (in the
case of medOil Shares held in certificated form) in the Form of Acceptance which
will accompany the Offer Document or as may be necessary in order to comply with
the City Code.



Capricorn reserves the right to waive all or any of conditions (b) to (i)
inclusive, in whole or in part.



Conditions (b) to (i) inclusive must be satisfied as at, or waived on or before,
midnight on the 21st day after the later of the first closing date of the Offer
and the date on which condition (a) is fulfilled (or in each such case such
later date as Capricorn may, with the consent of the Panel, agree), failing
which the Offer will lapse provided that Capricorn shall be under no obligation
to waive or treat as fulfilled any of conditions (b) to (i) inclusive by a date
earlier than the latest date specified above for the fulfilment thereof
notwithstanding that the other conditions of the Offer may at such earlier date
have been fulfilled and that there are at such earlier date no circumstances
indicating that any of such conditions may not be capable of fulfilment.



Except with the Panel's consent Capricorn will not invoke any of the above
conditions (except for the acceptance condition in (a) above) so as to cause the
Offer not to proceed, to lapse or to be withdrawn unless the circumstances which
give rise to the right to invoke the relevant conditions are of material
significance to Capricorn in the context of the Offer.



If Capricorn is required by the Panel to make an offer for the medOil Shares
under Rule 9 of the City Code, Capricorn may make such alteration to the terms
and conditions of the Offer as may be necessary to comply with the provisions of
the City Code.



The Offer will be governed by English law and will be subject to the exclusive
jurisdiction of the English courts.  The Offer will be subject to the applicable
requirements of the City Code, the Panel, the London Stock Exchange, the FSA and
other legal or regulatory requirements.



If the Offer is referred to the Competition Commission or the European
Commission initiates proceedings under Article 6(1)(c) of Council Regulation
(EC) No 139/2004 before the later of the first closing date of the Offer and the
date when the Offer becomes or is declared unconditional, the Offer will lapse.



If the Offer lapses, it will cease to be capable of further acceptance and
accepting medOil Shareholders, Capricorn and Jefferies International will cease
to be bound by the Forms of Acceptance submitted before the time the Offer
lapses.



The Offer will extend to all medOil Shares whilst the Offer remains open for
acceptance.



medOil Shares will be acquired under the Offer fully paid and free from all
liens, equities, charges, encumbrances, rights of pre-emption and any other
interests and together with all rights attaching thereto, including the rights
to receive and retain all dividends or other distributions declared, paid of
made on or after the date of the Offer.



Overseas Shareholders



The availability of the Offer to persons not resident in the United Kingdom may
be affected by the laws of the relevant jurisdictions and/or prohibited by the
laws of the relevant overseas jurisdictions. Persons who are not resident in the
United Kingdom should inform themselves about and observe any applicable
requirements in any other jurisdiction. It is the responsibility of any person
not resident in the United Kingdom wishing to accept the Offer to satisfy
himself as to the full observance of the laws of the relevant jurisdiction in
connection therewith, including the obtaining of any governmental, exchange
control or other consents which may be required, compliance with other
formalities needing to be observed and the payment of any issue, transfer or
other taxes due in such jurisdiction. Any such person will be responsible for
payment of any issue, transfer or other taxes, duties or other requisite payment
(s) due in such jurisdiction(s) by whomsoever payable, and Capricorn (and any
person acting on its behalf) shall be entitled to be fully indemnified and held
harmless by such person for any issue, transfer or other taxes or duties or
other requisite payments as Capricorn or any person acting on behalf of
Capricorn may be required to pay in respect of the Offer insofar as they relate
to such persons.
