Recommended acquisition of 
 
 
Rift Oil PLC 
 
at 13 pence per Rift Share 
 
 
by 
 
 
Talisman Energy Holdings Ltd. 
 
 
a wholly owned subsidiary of 
 
 
Talisman Energy Inc. 
 
 
Summary 
 
 
The Boards of Rift and Talisman are pleased to announce that they have reached 
an agreement on the terms of the recommended proposals for Talisman Holdings to 
acquire the entire issued and to be issued share capital of Rift for 13 pence 
per Rift Share. 
 
 
The Acquisition will be made on the following basis: 
 
 
13 pence in cash for each Rift Share. 
 
 
  *  The Acquisition represents a premium of approximately: 
 
 
 
-    30.0 per cent. to the Closing Price of 10.0 pence per Rift Share on 15 June 
2009, being the last Business Day  prior to this announcement; 
-    39.1 per cent. to the average Closing Price of approximately 9.3 pence per 
Rift Share over the 30 day trading period ended 15 June 2009; and 
-    72.8 per cent. to the average Closing Price of approximately 7.5 pence per 
Rift Share over the three month trading period ended 15 June 2009. 
 
 
  *  The terms of the Acquisition value Rift's existing issued share capital at 
  approximately GBP108.0 million and, on a fully diluted basis, at approximately 
  GBP114.8 million. 
 
 
 
  *  The Rift Directors consider the terms of the Acquisition to be fair and 
  reasonable and intend unanimously to recommend that Rift Shareholders vote in 
  favour of the Scheme Resolutions. 
 
 
 
  *  Talisman Holdings has received irrevocable undertakings to vote in favour of the 
  Scheme Resolutions in respect of a total of 268,564,851 Rift Shares 
  representing, in aggregate, approximately 32.3 per cent. of the existing issued 
  share capital of Rift, comprised as follows: 
 
 
 
(a)    from each of the Rift Directors and certain of their connected persons in 
respect of, in aggregate, 136,779,246 Rift Shares, representing approximately 
16.5 per cent. of the existing issued share capital of Rift. These undertakings 
will continue to be binding even if a competing offer is made for Rift which 
exceeds the value of the Acquisition and even if such higher offer is 
recommended for acceptance by the Board of Rift; and 
 
 
(b)    from certain other Rift Shareholders in respect of, in aggregate, 
131,785,605 Rift Shares, representing approximately 15.9 per cent. of the 
existing issued share capital of Rift. These undertakings will continue to be 
binding even if a competing offer is made for Rift unless such competing offer 
represents an improvement of not less than 10 per cent. on the value of the 
Acquisition. 
 
 
  *  Further details in relation to these irrevocable undertakings (including in 
  relation to the circumstances in which they cease to be binding) are contained 
  in Appendix 3 to this announcement. 
 
 
 
  *  The Directors of Rift, who have been so advised by Seymour Pierce, consider that 
  the terms of the Acquisition are fair and reasonable. In providing its advice, 
  Seymour Pierce has taken into account the commercial assessments of the 
  Directors. 
 
 
 
The Acquisition will be implemented by way of a scheme of arrangement under Part 
26 of the Act and in order to approve the terms of the Acquisition, Rift 
Shareholders will need to vote in favour of the Scheme Resolutions to be 
proposed at two meetings of Shareholders (the Court Meeting and the General 
Meeting) which are expected to be convened and held in July 2009. It is 
anticipated that a Scheme Document containing the notice of the two meetings 
will be sent to Rift Shareholders in late June 2009 following a hearing of the 
Court application to convene the Court Meeting. Talisman Holdings has, however, 
reserved the right to implement the Acquisition by way of an Offer. 
 
 
The Acquisition is also conditional on, amongst other things: 
 
 
  *  there being no legally binding agreement or arrangement with any third party 
  relating to the sale, transfer, disposal, farm out, earn out, carry or similar 
  of any interest in relation to either licence PPL 235 or PPL 261; and 
 
 
 
  *  licence PPL 235, which expires on 28 August 2009, being extended on terms 
  reasonably satisfactory to Talisman Holdings. 
 
 
 
The Board of Rift has confirmed to Talisman that all discussions relating to the 
possible farm out announced on 5 May 2009 have now ceased. 
 
 
Commenting on the Acquisition, Paul Blakeley, Executive Vice President, 
International Operations (East), of Talisman, said: 
 
 
"Talisman believes this offer represents the full and fair value of the assets 
and provides Rift shareholders the certainty of cash. The acquisition will 
provide a low-cost opportunity to aggregate gas in Southeast Asia, one of the 
growth areas of our portfolio" 
 
Ian Gowrie-Smith, Non-Executive Chairman of Rift, said: 
 
 
"The Board of Rift Oil PLC are pleased that years of investment and hard work 
have culminated in this offer for the Company at a price that we believe 
suitably rewards shareholders. It is time for those with more significant 
resources to take over the challenge of development and commercialisation"

Forward looking statements 
 
 
This announcement includes "forward-looking statements" relating to the 
Acquisition and the operations of Talisman and Rift that are, by their nature, 
subject to risks and uncertainties. These risks and uncertainties include 
possible competing bids or changes in the terms of the Acquisition; the risks of 
the oil and gas industry, such as operational risks in exploring for, developing 
and producing crude oil and natural gas and market demand; the uncertainty of 
reserves estimates; the uncertainty of estimates and projections relating to 
production, costs and expenses; potential delays or changes in plans with 
respect to exploration or development projects or capital expenditures; 
fluctuations in oil and gas prices, foreign currency exchange rates and interest 
rates; health, safety and environmental risks; uncertainties as to the 
availability and cost of financing; risks in conducting foreign operations (for 
example, political and fiscal instability or the possibility of civil unrest or 
military action); general economic conditions; the effect of acts of, or actions 
against, international terrorism; and the possibility that government policies 
or laws may change or governmental approvals may be delayed or withheld. Where 
not otherwise indicated, references to production volumes in this announcement 
are stated on a gross basis, which means they are stated prior to the deduction 
of royalties and similar payments. In this announcement, the calculation of 
barrels of oil equivalent (boe) is at a conversion rate of six thousand cubic 
feet (mcf) of natural gas for one barrel of oil (bbl). Boes may be misleading, 
particularly if used in isolation. A boe conversion ratio of 6 mcf:1 bbl is 
based on an energy equivalence conversion method primarily applicable at the 
burner tip and does not represent a value equivalence at the wellhead. For 
additional information identifying further factors, see Talisman's reports on 
file with Canadian securities regulatory authorities and the United States 
Securities and Exchange Commission. Talisman, Talisman Holdings and Rift assume 
no obligation and do not intend to update these forward-looking statements, 
except as required pursuant to applicable law. 
 
 
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 per cent. or more of any class of 
'relevant securities' of Rift, 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 p.m. (London time) on the Business Day following the date of the 
relevant transaction. This requirement will continue until the Scheme becomes 
effective, 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 Rift, 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 Rift by Talisman Holdings or Rift, or by 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 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.

16 June 2009 
 
 
Recommended acquisition of 
 
 
Rift Oil PLC 
 
at 13 pence per Rift Share 
 
 
by 
 
 
Talisman Energy Holdings Ltd. 
 
 
a wholly owned subsidiary of 
 
 
Talisman Energy Inc. 
 
 
 
 
1.    Introduction 
 
 
The Boards of Rift and Talisman are pleased to announce that they have reached 
an agreement on the terms of the recommended proposals for Talisman Holdings to 
acquire the entire issued and to be issued share capital of Rift for 13 pence 
per Rift Share. 
 
 
This announcement sets out the key terms of the Acquisition, which is to be 
effected by way of a scheme of arrangement under Part 26 of the Act, and 
explains the background to and the reasons why the Rift Directors intend 
unanimously to recommend that Rift Shareholders vote in favour of the Scheme 
Resolutions, as those Rift Directors who own Rift Shares have irrevocably 
undertaken to do in respect of their beneficial and certain of their connected 
holdings of Rift Shares. 
 
 
In order to approve the terms of the Acquisition, Rift Shareholders will need to 
vote in favour of the Scheme Resolutions to be proposed at two meetings of 
Shareholders (the Court Meeting and the General Meeting) which are expected to 
be held in July 2009. It is anticipated that the Scheme Document containing a 
notice of the two Rift Shareholders' meetings will be sent to Rift Shareholders 
in late June 2009 following a hearing of the Court application to convene the 
Court Meeting. 
 
2.    Summary of the recommended Acquisition 
 
 
Under the Scheme, which will be subject to the conditions and further terms set 
out below and in Appendix 1 and to be set out in the Scheme Document, Rift 
Shareholders holding Scheme Shares at the Scheme Record Time will receive: 
 
 
 13 pence in cash for each Rift Share. 
 
 
The Acquisition represents a premium of approximately: 
 
 
  *  30.0 per cent. to the Closing Price of 10.0 pence per Rift Share on 15 June 
  2009, being the last Business Day prior to this announcement; 
  *  39.1 per cent. to the average Closing Price of approximately 9.3 pence per Rift 
  Share over the 30 day trading period ended 15 June 2009; and 
  *  72.8 per cent. to the average Closing Price of approximately 7.5 pence per Rift 
  Share over the three month trading period ended 15 June 2009. 
 
 
 
The terms of the Acquisition value Rift's existing issued share capital at 
approximately GBP108.0 million and, on a fully diluted basis, at approximately 
GBP114.8 million. 
 
 
On the Scheme becoming effective, it will be binding on all holders of Rift 
Shares including any Rift Shareholders who did not vote to approve the Scheme or 
who voted against the Scheme. 
 
 
The Acquisition will be subject to the terms and conditions set out in Appendix 
1 of this announcement and also contained in the Scheme Document. The Scheme 
will not become effective and the Acquisition will not be completed unless the 
conditions set out in Appendix 1 of this announcement and the Scheme Document 
have been satisfied (or, if capable of waiver, waived) by 5.00 p.m. (London 
time) on 30 October 2009, or such later date as Talisman Holdings and Rift may 
agree and (if required) the Court may approve. 
 
 
In particular, the Acquisition is also conditional on: 
 
 
  *  there being no legally binding agreement or arrangement with any third party 
  relating to the sale, transfer, disposal, farm out, earn out, carry or similar 
  of any interest in relation to either licences PPL 235 or PPL 261; and 
 
 
 
  *  licence PPL 235, which expires on 28 August 2009, being extended on terms 
  reasonably satisfactory to Talisman Holdings. 
 
 
 
The Board of Rift has confirmed to Talisman that all discussions relating to the 
possible farm out announced on the 5 May 2009 have now ceased. If Talisman 
Holdings is unable to rely on the condition above or the Acquisition otherwise 
completes before licence PPL 235 has been extended, the Rift Directors and their 
connected persons have agreed to have 75 per cent. of the consideration due to 
them under the terms of the Acquisition (excluding funds arising on the disposal 
of Rift Shares issued after today on the exercise of Rift Options) withheld in 
escrow upon the closing of the Acquisition. The funds held in escrow will be 
released to the Rift Directors and their connected persons if licence PPL 235 is 
extended, on terms reasonably satisfactory to Talisman Holdings, within 12 
months of the closing of the Acquisition; otherwise these funds will be returned 
to Talisman. 
 
3.    Irrevocable undertakings 
 
 
Talisman Holdings has received irrevocable undertakings to vote in favour of the 
Scheme Resolutions in respect of a total of 268,564,851 Rift Shares 
representing, in aggregate, approximately 32.3 per cent. of the existing issued 
share capital of Rift, comprised as follows: 
 
 
(a)    from each of the Rift Directors and certain of their connected persons in 
respect of Rift Shares held by them and, in certain cases, by their connected 
persons, and certain other Rift Shareholders in respect of their entire 
beneficial holdings which amount, in aggregate, to 136,779,246 Rift Shares, 
representing approximately 16.5 per cent. of the existing issued share capital 
of Rift. These undertakings will continue to be binding even if a competing 
offer is made for Rift which exceeds the value of the Acquisition and even if 
such higher offer is recommended for acceptance by the Board of Rift; and 
 
 
(b)    from certain other Rift Shareholders in respect of, in aggregate, 
131,785,605 Rift Shares, representing approximately 15.9 per cent. of the 
existing issued share capital of Rift. These undertakings will cease to be 
binding in certain circumstances if: 
(i)     a person not acting in concert with Talisman Holdings announces prior to 
the date by which proxy forms are to be received in respect of the Scheme, a 
firm intention to make an offer for Rift which represents an improvement of at 
least 10 per cent. per Rift Share over the value of the consideration available 
under the Acquisition; and 
(ii)     Talisman Holdings fails to announce, at or prior to 11.59 p.m. on the 
fourteenth day after such higher offer is announced, a revision to the terms of 
the Acquisition which represents an improvement to the consideration per Rift 
Share available under such higher offer. 
 
 
Further details of these irrevocable undertakings (including in relation to the 
circumstances in which they cease to be binding) are contained in Appendix 3 to 
this announcement. 
 
4.    Information on Talisman and Talisman Holdings 
 
 
Talisman, which is listed on the Toronto and the New York stock exchanges under 
the symbol TLM, is an independent North American based oil and gas producer with 
global operations that was established in 1992. Talisman produced, on average, 
over 430,000 boe/d in the year ending December 2008 of which approximately 50 
per cent. was oil and liquids and 50 per cent. was natural gas. Talisman has a 
diversified, global portfolio with its main operating areas in North America, 
the North Sea and Southeast Asia. 
 
 
Talisman currently has a market capitalisation of more than C$16 billion. For 
the year ended 31 December 2008, Talisman recorded a profit after tax of C$3,519 
million (2007: profit of C$2,078 million) and had net assets at that date of 
C$11,150 million. 
 
 
Talisman Holdings was established as a wholly owned subsidiary of Talisman in 
December 2002. Since that time it has not carried out any trading activity but 
has served as an intermediate holding company for an offshore finance 
subsidiary. 
 
 
Further financial information on Talisman and Talisman Holdings will be set out 
in the Scheme Document. 
 
5.    Background to and reasons for the Acquisition 
 
 
Southeast Asia continues to be an area of opportunity for Talisman. It is a 
region characterised by long-life assets in a low cost environment. In the past 
five years, Talisman has doubled its production in the area and is positioned to 
grow at 10 per cent. per annum over the next few years. 
 
 
The price per share offered to Rift Shareholders under the Acquisition reflects 
the value that Talisman attributes to the three gas discoveries at Puk Puk, 
Douglas Main and Langia, and the possibility for future value creation from the 
drilling of the exploration prospects currently outlined by Rift. 
 
 
Talisman believes that Rift's portfolio combined with its own larger diversified 
asset portfolio, with a balance of production and exploration opportunities, 
will provide a strong platform for its continued and future growth within 
Southeast Asia. 
 
6.    Background to and reasons for recommending the Acquisition 
 
 
After a successful exploration campaign on PPL 235 and the discovery of gas and 
oil condensates at Douglas, Puk-Puk and Langia, the Rift Board had a number of 
options available to it with respect to commercialisation. Given the scale of 
Rift's discoveries and the early stage of gas exploitation in Papua New Guinea 
("PNG"), the Rift Board has always articulated the need for a partner to realise 
full value in the move from discovery to exploitation. In March 2007, Rift 
signed a memorandum of understanding ("MOU") with Alcan South Pacific Pty Ltd. 
("Alcan") to develop the idea of supplying their Gove alumina facility with gas 
from Rift's discoveries. Additionally, Rift signed a MOU with Flex LNG in June 
2008 to progress the concept of developing a floating liquefied natural gas 
offtake opportunity for Rift's gas. 
 
 
In December 2008, Rift announced that it had entered into a formal process with 
RFC Group Limited and RBC to review the strategic alternatives available to it. 
Given the depressed state of the financial markets at that time, the outlook for 
oil and gas companies and the early nature of the discussions with Alcan and 
Flex LNG, the Rift Board felt it was prudent to fully assess the options 
available to it to fund and develop PPL 235 and PPL 261. 
 
 
Following a comprehensive process, during which a broad range of parties were 
contacted, Rift announced, on 5 May 2009, that it had received a proposal from a 
major multi-national oil company to fund the drilling of up to four wells and 
100km of seismic on its PPL 235 licence in Papua New Guinea in return for a 
significant equity interest in the licence. 
 
 
The proposal was subject to further negotiation and agreement of the formal 
documents, the satisfaction of a number of pre-conditions, various Government 
approvals and the signing of definitive farm-in and joint operating agreements. 
Under this proposal Rift would retain 100 per cent. of the rights to the 
adjoining licence PPL 261, which the Rift Board regard as highly prospective. 
 
 
At that time the proposed farm-in offer was the most preferred of a number of 
offers to emerge from the formal process. 
 
 
Following the announcement made on 5 May 2009, the Rift Board received an 
approach from Talisman, who had been contacted as part of the formal strategic 
review, outlining an indicative offer to acquire the entire issued share capital 
of the Company at a substantial premium to the prevailing share price. In 
reaching its view to recommend that Rift Shareholders accept the Acquisition, in 
light of the proposal already in contemplation with the major multi-national oil 
company, the Rift Board considered a number of factors. 
 
 
To fully exploit the Company's assets in PNG, Rift would be obliged to raise 
substantial amounts of capital either from the capital markets or from industry 
partners in the future. Given the challenging economic environment and depressed 
state of the capital markets in recent times, the Rift Board considers that 
there would be limited appetite from investors to support Rift throughout the 
exploration and development phase of its work programme. In addition, any 
funding from industry partners would reduce Rift's interest in the assets and 
any ultimate return to Rift Shareholders. 
 
 
The Consideration represents a substantial premium to the Rift share price and, 
when weighed against the risks inherent in any project of this size and the lag 
time to commercialisation, the Directors of Rift intend unanimously to recommend 
that Rift Shareholders vote in favour of the Scheme Resolutions to enable the 
Acquisition to be effected. 
 
7.    Directors' recommendation 
 
 
The background and reasons for recommending the Acquisition are set out under 
section 6 above of this announcement. 
 
 
The Directors of Rift, who have been so advised by Seymour Pierce, consider that 
the terms of the Acquisition are fair and reasonable. In providing its advice, 
Seymour Pierce has taken into account the commercial assessments of the 
Directors. Accordingly, the Rift Directors intend unanimously to recommend that 
Rift Shareholders vote in favour of the Scheme Resolutions. 
 
 
The Directors of Rift and certain of their connected parties have irrevocably 
undertaken to vote in favour of the Scheme Resolutions in respect of their own 
beneficial holdings and certain of their connected holdings, amounting, in 
aggregate, to 136,779,246 Rift Shares, representing 16.5 per cent. of Rift's 
issued share capital. 
 
8.    Implementation Agreement 
 
 
Rift and Talisman Holdings today entered into the Implementation Agreement which 
sets out the arrangements between them in relation to the implementation of the 
Scheme. Each party to the Implementation Agreement has agreed to implement the 
Scheme and to co-operate with the other on the terms set out in the 
Implementation Agreement. In addition, Rift has entered into certain 
undertakings concerning the conduct of its business during that period. 
 
 
Rift has agreed, pursuant to the Implementation Agreement, to pay Talisman 
Holdings an inducement fee of GBP892,000 (exclusive of recoverable VAT or 
equivalent sales or revenue tax if any). Such fee shall be payable if: 
 
 
(a)    before the Scheme or the Offer (as applicable) lapses, is withdrawn, 
terminates or otherwise fails or (with the consent of the Panel) is not made, an 
announcement regarding an Alternative Proposal is made provided that such 
Alternative Proposal subsequently becomes effective; 
(b)    the Rift Directors do not unanimously and without qualification recommend 
the Rift Shareholders to vote in favour of the Scheme at the Court Meeting and 
in favour of the Resolutions at the GM in the Scheme Document or, if the 
Talisman Holdings elects to implement the Acquisition by means of the Offer, the 
Rift Directors do not in the Offer Document unanimously and without 
qualification recommend the Rift Shareholders to accept the Offer (save in 
either case following an announcement regarding an Alternative Proposal, in 
which case, paragraph (a) will apply); 
(c)    the Rift Directors withdraw, qualify or adversely modify their 
recommendation or agree or resolve to do the same (save in either case following 
an announcement regarding an Alternative Proposal, in which case, paragraph (a) 
will apply); 
(d)    all conditions to which the Scheme is subject other than the conditions 
set out at paragraph (a) of Part A of Appendix 1 to this announcement have been 
satisfied or waived and the resolutions to be proposed at the Court Meeting and 
the GM have been passed by the requisite majorities, but the Rift Directors do 
not seek either of the Court Orders or do not file all requisite documentation 
with the Registrar, in either case, in accordance with the timetable set out in 
the schedule to the Implementation Agreement; 
(e)    Rift breaches the terms of the Implementation Agreement and Talisman 
Holdings elects to terminate it pursuant to its terms. 
Pursuant to Rule 21.2 of the Code, RBC has confirmed to the Panel that it 
considers these arrangements to be in the best interests of Rift Shareholders. 
 
 
Pursuant to the Implementation Agreement, Rift has also agreed with Talisman 
Holdings that, in summary: 
 
 
  *  it will not, directly or indirectly, solicit any Alternative Proposal; and 
 
 
 
  *  in the event that Rift receives an Alternative Proposal which is superior from a 
  financial point of view to the Acquisition, the Directors of Rift will not 
  withdraw or qualify their recommendation of the Acquisition unless either (i) 
  Talisman Holdings fails to confirm within 72 hours following Talisman Holdings 
  being notified of such proposal by Rift that it intends to increase the value of 
  the Acquisition to a value per Rift Share equal to or greater than that provided 
  for under the relevant Alternative Proposal, or (ii) if Talisman Holdings has so 
  confirmed to Rift, but then fails to announce such increase within five Business 
  Days of such confirmation by Talisman Holdings, 
 
 
 
in each case until the Scheme terminates or lapses in accordance with its terms 
or, as applicable, the Offer is withdrawn by Talisman Holdings (with the consent 
of the Panel, if required) or lapses or the Implementation Agreement is 
otherwise terminated in accordance with its terms. 
 
 
Rift has also agreed neither, at any stage prior to the Scheme terminating or 
lapsing or, as applicable, the Offer being withdrawn by Talisman Holdings (with 
the consent of the Panel, if required) or lapsing or the Implementation 
Agreement being otherwise terminated in accordance with its terms, to pay nor to 
enter into any agreement to pay an inducement fee or a break fee to a third 
party. 
 
 
Further details of the Implementation Agreement will be set out in the Scheme 
Document. 
 
9.    Financing the Acquisition 
 
 
The cash consideration payable under the Acquisition will be funded through the 
existing cash resources of Talisman. Tristone Capital is satisfied that 
sufficient financial resources are available to Talisman to satisfy in full the 
cash consideration payable to Rift Shareholders pursuant to the Acquisition. 
 
10.    Information on Rift 
 
 
Rift was established in late 2004 to acquire a 65 per cent. operated interest in 
the PPL 235 licence in western Papua New Guinea. It acquired this interest 
through its subsidiary, Foreland Oil Limited, from Austral Pacific Energy 
Limited ("Austral"), who owned the remaining 35 per cent., in return for a 
commitment to spend $6 million on exploration and development. 
 
 
Rift and Austral entered into a joint venture agreement in early 2005 and 
drilling on the first prospect on PPL 235, Douglas-1, commenced in April 2006. 
The Company announced a gas discovery on Douglas 1 on 1 June 2006. 
 
 
Rift listed on AIM on 19 April 2006. Since then it has centred its activities on 
developing its 100 per cent. owned licences PPL 235 and PPL 261 on the Foreland 
Basin in Papua New Guinea. 
 
 
In November 2006, licence PPL 261 was awarded, under which a 50 per cent. 
interest was granted to Rift (operator) and a 50 per cent. interest to Austral 
(through their respective subsidiaries Foreland Oil Limited and Trans-Orient 
Petroleum (PNG) Ltd.). 
 
 
Following the discovery at Douglas-1, Rift turned its attention to the 
commercialisation of the potential resource at PPL 235 and entered into a 
memorandum of understanding with Alcan to investigate the supply of 
approximately 40 bcf of gas per annum over 20 years to Alcan's Gove Refinery in 
the Northern Territory of Australia. However, as the resource potential of PPL 
235 has increased the Company has shifted its focus to the liquefied natural gas 
market, entering into a memorandum of understanding with Flex LNG in June 2008 
which it was then felt could potentially be more economically attractive to 
Rift. 
 
 
In May 2008, Rift announced that it had reached an agreement with Austral, 
resulting in Rift assuming 100 per cent. ownership of Licences PPL 261 and PPL 
235 as well as the Coral Sea Drilling Rig for a total payment of US$5 million. 
 
 
Drilling of Puk Puk 1, the second prospect on PPL 235, commenced in April 2008 
and Rift announced its discovery at Puk Puk in late July with internal 
management estimates putting the potential mid case contingent resource for Puk 
Puk at 430 bcf and 8.5 mmbbl of condensate, approximately doubling pre-drilling 
estimates. This estimate, together with the 250 bcf already identified on the 
Douglas and Langia structures, brought the total mid case contingent resource 
estimate of these structures alone to approximately 700 bcf without establishing 
additional reserves from further untested adjoining structures. 
 
 
Further financial information on Rift will be set out in the Scheme Document. 
 
11.    Current trading and prospects of Rift 
 
 
The final results for the year ended 31 March 2009 for Rift are due to be 
released later today. 
 
 
During the financial year, Rift raised GBP6.2 million before expenses from 
investors by way of secondary equity placings and the proceeds of these 
fundraisings were applied in the work programmes that have been carried out on 
the Company's licence area PPL 235 which included the drilling of Puk Puk 1 and 
the acquisition of 210km seismic over the licence block. 
 
 
Together with the proceeds from the exercise of RBC's warrants, announced today, 
and Rift's current cash at hand, Rift's cash position will be approximately 
GBP700,000. Going forward, Rift will be required to fund the work commitments on 
its licence block PPL 261 and continuing fixed overheads and corporate G&A. In 
the absence of the Acquisition proceeding, these work commitments and ongoing 
overheads will necessitate further fundraisings in the near term. 
 
12.    Management and employees 
 
 
Talisman intends to fulfil all contractual and statutory requirements pertaining 
to the employment of all existing management and employees of Rift. Talisman 
will meet with the management and employees of Rift, as soon as deemed 
appropriate by the Directors of Rift, to discuss and better understand their 
responsibilities and career aspirations. 
 
13.    Rift Share Options 
 
 
The terms of the Acquisition will extend to all Rift Shares which are 
unconditionally allotted or issued fully paid (or credited as fully paid), 
including any which are also allotted and issued pursuant to the exercise of 
existing options granted by Rift to Rift Optionholders, prior to the Scheme 
Effective Date. 
 
 
Rift Optionholders will, to the extent that their Rift Options are not already 
exercisable, become entitled to exercise all their options when the Scheme is 
sanctioned by the Court. Talisman Holdings will, in due course, make appropriate 
proposals to the Rift Optionholders in respect of these subsisting options. 
 
The Scheme Document will contain full details of the actions that the Rift 
Optionholders may take in respect of their outstanding Rift Options. 
 
14.    Rift Warrants 
 
 
Appropriate proposals will be made in due course to holders of Rift Warrants. 
Details of these proposals will be set out in the Scheme Document or, as the 
case may be, the Offer Document and in separate letters to be sent to holders of 
Rift Warrants. 
 
 
The holders of 75 per cent. of the 2009 Warrants have approved changes to the 
terms and particulars of such Rift Warrants in order to facilitate the 
Acquisition by way of the Scheme and irrevocably undertaken to accept proposals 
to be put to them by Talisman Holdings in relation to their Rift Warrants, 
provided that the value of consideration available to them is equal to or 
greater than the net value of consideration that would be available under the 
Scheme if the Rift Warrants were converted to ordinary shares of 1 penny each in 
the capital of Rift prior to the Scheme becoming effective. 
 
 
Rift and Talisman will seek the approval of the holders of the February 2007 
Warrants to also change the terms and particulars of such Rift Warrants in order 
to facilitate the Acquisition by way of Scheme. The Scheme is conditional on 
this approval being given by holders entitled to subscribe for not less than 75 
per cent. of the ordinary shares in the capital of the Company subject to the 
February 2007 Warrants. If the Acquisition were implemented by way of the Offer, 
the Offer would not be conditional on the approval of the holders of the 
February 2007 Warrants. 
 
15.    Rift Shareholder Meetings 
 
 
The Scheme will require approval of Rift Shareholders at the Court Meeting and 
the General Meeting. It is expected that those meetings will be held in July 
2009, however, the exact dates and time will only be determined following the 
application to Court to convene the Court Meeting. The Scheme Document will 
contain the notices of the Court Meeting and the General Meeting. The special 
resolution to be proposed at the General Meeting is to approve the Scheme and 
other related matters, including, inter alia, the reduction of Rift's share 
capital, amendments to the Rift Articles required to implement the Scheme and 
the cancellation of the admission to trading of Rift Shares on AIM. The approval 
required at the Court Meeting is a majority in number of those Rift Shareholders 
present and voting, whether in person or by proxy, representing not less than 75 
per cent. in value of the Rift Shares held by such shareholders. 
 
 
The implementation of the Scheme can only take place if all of the conditions, 
as set out in Appendix 1 to this announcement, have been satisfied or, where 
relevant, waived. Assuming the satisfaction, or where appropriate, waiver of 
such conditions, the Scheme will become effective on the delivery to the 
Registrar of Companies in England and Wales by Rift of the Court order 
sanctioning the Scheme (and related reduction of capital) and the registration 
of such Court order. Once the Scheme becomes effective it will be binding on all 
holders of Rift Shares, including any holders who did not vote to approve the 
Scheme. 
 
 
It is anticipated that the Scheme Document setting out full details of the 
Acquisition and the Scheme, together with notices of the Court Meeting and 
General Meeting and the expected timetable, will be posted to Rift Shareholders 
in late June 2009 following a hearing of the application in Court to convene the 
Court Meeting. 
 
16.    Overseas shareholders 
 
 
The implications of the Scheme for Overseas Shareholders may be affected by the 
laws of the relevant jurisdiction. Such Overseas Shareholders should inform 
themselves about and observe any applicable legal requirements. It is the 
responsibility of each Overseas Shareholder 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, or the compliance with other necessary formalities which 
are required to be observed and the payment of any issue, transfer or other 
taxes due in such jurisdiction. 
 
 
Further details in relation to Overseas Shareholders will be contained in the 
Scheme Document. 
 
17.    Disclosure of interests in relevant securities of Rift 
 
 
At the date of this announcement, Talisman Holdings does not own any of the 
issued share capital of Rift. 
 
 
As at the date of this announcement, save as disclosed above (including the 
irrevocable undertakings referred to above and the Rift Shares represented 
thereby), neither Talisman Holdings nor, so far as the Directors of Talisman 
Holdings are aware, any person acting in concert with it has any interest in or 
right to subscribe for any relevant securities of Rift nor are they party to any 
short positions (whether conditional or absolute and whether in money or 
otherwise) relating to relevant securities of Rift, including any short 
positions under derivatives, agreements to sell or any delivery obligations or 
rights to require another person to purchase or take delivery of any relevant 
securities of Rift nor does any such person have any arrangement in relation to 
relevant securities of Rift. Neither Talisman Holdings nor the Directors of 
Talisman Holdings nor, so far as Talisman Holdings is aware, any person acting 
in concert with Talisman Holdings, has borrowed or lent any relevant securities 
of Rift. 
 
 
For these purposes, 'interest' includes any long economic exposure, whether 
conditional or absolute, to changes in the prices of securities. A person is 
treated as having an 'interest' by virtue, inter alia, of the ownership or 
control of securities or by virtue of any option in respect of, or derivative 
referenced to, securities. 'Relevant securities' in Rift include any securities 
of Rift which are being offered for pursuant to the Acquisition or carry voting 
rights, any equity share capital of Rift and any securities of Rift carrying 
conversion or subscription rights into any of the foregoing. 
 
18.    Cancellation of trading, compulsory acquisition and re-registration as a 
private company 
 
 
It is intended that the London Stock Exchange will be requested to cancel 
trading in Rift Shares on AIM on, or shortly after, the date on which the Scheme 
becomes effective. 
 
 
If the Acquisition is effected by way of the Offer, it is anticipated that 
cancellation of listing and trading will take effect no earlier than 20 Business 
Days after Talisman Holdings has acquired or agreed to acquire 75 per cent. of 
the voting rights attaching to the Rift Shares. 
 
 
The cancellation of admission to trading on AIM of Rift Shares would 
significantly reduce the liquidity and marketability of any Rift Shares not 
assented to the Offer at that time. If the Acquisition is effected by way of the 
Offer and Talisman Holdings receives acceptances under the Offer in respect of, 
and/or otherwise acquires, 90 per cent. or more of the Rift Shares and voting 
rights to which the Offer relates, Talisman Holdings intends to exercise its 
rights to acquire compulsorily the remaining Rift Shares in respect of which the 
Offer has not been accepted. 
 
 
It is intended that as soon as practicable following the Scheme becoming 
effective Rift will be re-registered as a private limited company.

an offer to sell or an invitation to purchase or the solicitation of an offer to 
subscribe for any securities or the solicitation of any vote or approval in any 
jurisdiction pursuant to the Acquisition or otherwise. Rift Shareholders are 
advised to read carefully the formal documentation in relation to the 
Acquisition once it has been despatched. 
 
 
The release, distribution or publication of this announcement in jurisdictions 
other than the UK may be restricted by law and therefore any persons who are 
subject to the laws of any jurisdiction other than the UK should inform 
themselves about and observe any applicable requirements. Copies of this 
announcement and any documentation relating to the Acquisition are not being, 
and must not be, directly or indirectly, mailed or otherwise forwarded, 
distributed or sent in or into or from any Restricted Jurisdiction and persons 
receiving such documents (including custodians, nominees and trustees) must not 
mail or otherwise forward, distribute or send such documents in or into or from 
a Restricted Jurisdiction. If the Acquisition is implemented by way of the 
Offer, (unless otherwise determined by Talisman Holdings and permitted by 
applicable law and regulation) it will not be made, directly or indirectly, in 
or into, or by the use of the mails, or by any means of instrumentality 
(including without limitation, telephonically or electronically) of interstate 
or foreign commerce of, or any facilities of a national securities exchange of 
any Restricted Jurisdiction, and the Offer will not be capable of acceptance 
from or within any Restricted Jurisdiction. 
 
 
Forward looking statements 
 
 
This announcement includes "forward-looking statements" relating to the 
Acquisition and the operations of Talisman and Rift that are, by their nature, 
subject to risks and uncertainties. These risks and uncertainties include 
possible competing bids or changes in the terms of the Acquisition; the risks of 
the oil and gas industry, such as operational risks in exploring for, developing 
and producing crude oil and natural gas and market demand; the uncertainty of 
reserves estimates; the uncertainty of estimates and projections relating to 
production, costs and expenses; potential delays or changes in plans with 
respect to exploration or development projects or capital expenditures; 
fluctuations in oil and gas prices, foreign currency exchange rates and interest 
rates; health, safety and environmental risks; uncertainties as to the 
availability and cost of financing; risks in conducting foreign operations (for 
example, political and fiscal instability or the possibility of civil unrest or 
military action); general economic conditions; the effect of acts of, or actions 
against, international terrorism; and the possibility that government policies 
or laws may change or governmental approvals may be delayed or withheld. Where 
not otherwise indicated, references to production volumes in this announcement 
are stated on a gross basis, which means they are stated prior to the deduction 
of royalties and similar payments. In this announcement, the calculation of 
barrels of oil equivalent (boe) is at a conversion rate of six thousand cubic 
feet (mcf) of natural gas for one barrel of oil (bbl). Boes may be misleading, 
particularly if used in isolation. A boe conversion ratio of 6 mcf:1 bbl is 
based on an energy equivalence conversion method primarily applicable at the 
burner tip and does not represent a value equivalence at the wellhead. For 
additional information identifying further factors, see Talisman's reports on 
file with Canadian securities regulatory authorities and the United States 
Securities and Exchange Commission. Talisman, Talisman Holdings and Rift assume 
no obligation and do not intend to update these forward-looking statements, 
except as required pursuant to applicable law. 
 
 
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 per cent. or more of any class of 
'relevant securities' of Rift, 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 p.m. (London time) on the Business Day following the date of the 
relevant transaction. This requirement will continue until the Scheme becomes 
effective, 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 Rift, 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 Rift by Talisman Holdings or Rift, or by 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 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.

with regard to the disposal, spillage, release, discharge, leak or emission of 
any waste or hazardous substance or any substance likely to impair the 
environment or harm human health or animal health or otherwise relating to 
environmental matters, or that there has otherwise been any such disposal, 
spillage, release, discharge, leak or emission (whether or not the same 
constituted a non-compliance by any person with any such legislation or 
regulations, and wherever the same may have taken place) any of which disposal, 
spillage, release, discharge, leak or emission would be likely to give rise to 
any liability (actual or contingent) on the part of any member of the Wider Rift

supranational, statutory or other regulatory body, agency, court, association or 
any other person or body in any jurisdiction and which is material in the 
context of the Wider Rift Group taken as a whole. 
For the purposes of these conditions the "Wider Rift Group" means Rift and its 
subsidiary undertakings, associated undertakings and any other undertaking in 
which Rift and/or such undertakings (aggregating their interests) have a 
significant interest and the "Wider Talisman Group" means Talisman and its 
subsidiary undertakings, associated undertakings and any other undertaking in 
which Talisman and/or such undertakings (aggregating their interests) have a 
significant interest and for these purposes "subsidiary undertaking" and 
"undertaking" have the meanings given by the Companies Act 2006, "associated 
undertaking" has the meaning given by paragraph 19 of Schedule 6 to the Large 
and Medium-sized Companies and Groups (Accounts and Reports) Regulations 2008 
other than paragraph 19(1)(b) of Schedule 6 to those Regulations which shall be 
excluded for this purpose, and "significant interest" means a direct or indirect 
interest in ten per cent. or more of the equity share capital (as defined in the 
Companies Act 2006). 
Talisman Holdings reserves the right to waive, in whole or in part, all or any 
of conditions (a) to (j) above, except for condition (a). 
 
 
Talisman Holdings shall be under no obligation to waive (if capable of waiver) 
or treat as satisfied any of conditions (b) to (j) (inclusive) by a date earlier 
than the latest date specified above for the satisfaction thereof, 
notwithstanding that the other conditions of the offer may at such earlier date 
have been waived or fulfilled and that there are at such earlier date no 
circumstances indicating that any of such conditions may not be capable of 
fulfilment. 
 
 
If Talisman Holdings is required by the Panel to make an offer for Rift Shares 
under the provisions of Rule 9 of the Code, Talisman Holdings may make such 
alterations to any of the above conditions as are necessary to comply with the 
provisions of that Rule. 
 
 
Talisman Holdings reserves the right to elect (with the consent of the Panel) to 
implement the Acquisition by way of a takeover offer (as defined in Part 28 of 
the Companies Act 2006) as it may determine in its absolute discretion. In such 
event, such offer will be implemented on the same terms, so far as applicable, 
as those which would apply to the Scheme, subject to appropriate amendments to 
reflect the change in method of effecting the Acquisition, including (without 
limitation and subject to the consent of the Panel) an acceptance condition set 
at 90 per cent. (or such lesser percentage, being more than 50 per cent., as 
Talisman Holdings may decide): (i) in nominal value of the shares to which such 
offer relates; (ii) of the voting rights attached to those shares; and (iii) of 
the voting rights normally exercisable at a general meeting of Rift, including, 
for this purpose, any such voting rights attaching to Rift Shares that are 
unconditionally allotted or issued before the takeover offer becomes or is 
declared unconditional as to acceptances, whether pursuant to the exercise of 
any outstanding subscription or conversion rights or otherwise. 
 
 
If Talisman Holdings elects (with the consent of the Panel) to implement the 
Acquisition by way of the Offer, the Offer will not be subject to condition (d) 
above. 
 
 
This Acquisition will be governed by English law and be subject to the 
jurisdiction of the English courts, to the conditions set out below and in the 
formal Scheme Document and to the applicable rules and regulations of the 
Financial Services Authority, the London Stock Exchange and the Code. 
 
 
Part B:    Certain further terms of the Offer 
 
 
In the event that the Acquisition is to be implemented by way of the Offer, the 
Rift Shares which will be acquired under the Offer will be acquired fully paid 
and free from all liens, equities, charges, encumbrances, options, rights of 
pre-emption and any other third party rights and interests of any nature and 
together with all rights now or hereafter attaching or accruing to them, 
including voting rights and the right to receive and retain in full all 
dividends and other distributions (if any) declared, made or paid on or after 
the date of this announcement.

IRREVOCABLE UNDERTAKINGS 
 
 
Each of the Directors of Rift and/or certain of their connected persons has 
delivered an undertaking to Talisman Holdings pursuant to which each has 
irrevocably undertaken to vote in favour of the Scheme (or, if applicable to 
accept the Offer) in respect of Rift Shares held by them and, in certain cases, 
by their connected persons in respect of their entire beneficial holdings which 
amount, in aggregate, to 136,779,246 Rift Shares, representing approximately 
16.47 per cent. of the existing issued share capital of Rift. These undertakings 
will continue to be binding even if a competing offer is made for Rift which 
exceeds the value of the Acquisition and even if such higher offer is 
recommended for acceptance by the Board of Rift. However, these undertakings 
shall cease to be binding if the Scheme or Offer lapses or is withdrawn. 
 
 
The following table shows the number of Rift Shares in which each of the Rift 
Directors and, in certain cases, their connected persons had an interest on the 
date of the irrevocable undertaking given by him, and in respect of which an 
irrevocable undertaking was given:

In addition, Talisman Holdings has received irrevocable undertakings to vote in 
favour of the Scheme (or, if applicable to accept the Offer) from certain other 
Rift Shareholders, which amount, in aggregate, to 131,785,605 Rift Shares, 
representing approximately 15.87 per cent. of the existing issued share capital 
of Rift. These undertakings will continue to be binding even if a competing 
offer is made for Rift unless: 
 
 
(a)    a person not acting in concert with Talisman Holdings announces prior to 
the date by which proxy forms are to be received in respect of the Scheme, a 
firm intention to make an offer for Rift which represents an improvement of at 
least 10 per cent. per Rift Share over the value of the consideration available 
under the Acquisition; and 
(b)    Talisman Holdings fails to announce, at or prior to 11.59 p.m. on the 
fourteenth day after such higher offer is announced, a revision to the terms of 
the Acquisition which represents an improvement to the consideration per Rift 
Share available under such higher offer; or 
(c)    the Scheme or Offer lapses or is withdrawn.
