                      SOUND OIL SHARES RE-ADMITTED TO AIM

                 COMPLETION OF ACQUISITION OF MITRA AND PLACING

Sound Oil (AIM: SOU), the upstream oil and gas company, announces that its
ordinary shares were re-admitted to AIM earlier today and that accordingly it
has completed the acquisition of the entire issued share capital of Mitra and
the Placing. Following the Acquisition and the Placing, the number of issued
ordinary shares in the Company is 692,427,348.

Information on Sound Oil

Sound Oil was incorporated on 27 January 2005 and first admitted to trading on
AIM on 29 June 2005 when it raised £10.8 million (after expenses) with the then
stated intention of evaluating and making investments in energy resource
business opportunities in North and West Africa.

The Company has evaluated a number of investments since it was first admitted to
trading on AIM. Initially the Company focused its efforts on offshore areas of
West Africa, but towards the end of 2005 the Company began to extend the area of
evaluation outside Africa to decide whether there was better value elsewhere,
while also continuing to review opportunities in that region. The Company
subsequently entered into discussions with the directors of Mitra with a view to
acquiring Mitra. The Existing Directors believe that the Acquisition will
enhance shareholder value and be in the best interests of both companies and
their shareholders. Through the Acquisition the Company will obtain a 34.99 per
cent. working interest in the Bangkanai PSC and a 20 per cent. working interest
in the Citarum PSC.

On 22 May 2006, the Company announced that it had entered into an agreement
under which it may acquire an interest in a production sharing agreement
relating to an exploration area in Bangladesh (the "Bangladesh PSC").  The
operator of the PSC is Ocean Bangladesh Corporation.  This transaction is 
subject to the extension of the PSC and the approval of, the appropriate 
Bangladesh authorities.

Further information on Mitra, the Bangkanai PSC, the Citarum PSC and the
Bangladesh Block 22 is set out below.

Information on Mitra

Mitra is an unquoted Mauritian company formed in 2004 by its three directors who
are interested in 93.7 per cent. of Mitra's issued ordinary shares. Mitra has a
34 per cent. interest in the Bangkanai PSC and a 20 per cent. interest in the
Citarum PSC. Mitra has not generated any revenue to date; it incurred a loss of
US$1.2 million in the year ended 31 December 2005 and its net assets at that
date were US$0.7 million.

Bangkanai Production Sharing Contract

The Bangkanai PSC encompasses an area of 6,976 km2, located approximately 200
kilometres west of Balikpapan and 330 kilometres north of Banjarmasin, the
provincial capitals of East and West Kalimantan respectively. The block is
situated on the west side of the Kutei Basin and the northern edge of the stable
Barito Shelf. The area was previously part of a larger production sharing
contract awarded to Unocal in 1972. During this period Unocal shot two 2D
seismic surveys in 1975 and 1985/1986 and drilled ten exploration wells and two
appraisal wells. The only discovery to date is the Kerendan gas field made in
1982. Although Unocal's plan of production for Kerendan was approved in 1997,
they were unable to secure a gas sales agreement for the gas, and relinquished
the contract in 2000. The Bangkanai PSC, covering a large area in which only six
wells have been drilled, including three Kerendan wells, was awarded to EBE on
30 December 2003 for a 30 year period, including an exploration period of 10
years. In September 2004 MEB (a subsidiary of Mitra) farmed in to the licence
(49 per cent.) (the "MEB Farm-In"). It has recently signed a sale and purchase
agreement for the sale of part of its farm-in interest to Medco (the "Medco
Farm-In"). This sale is not yet complete, but at completion the resulting
interests will be: EBE 51 per cent. operator; MEB 34 per cent.; and Medco 15 per
cent.

Citarum Production Sharing Contract

The Citarum PSC covers an area of 4,440 km2 in Central West Java. The northern
margin of the block is characterised by hilly terrain which is moderately
populated. The southern block is generally more mountainous and in part covered
by volcanic rock. The block is situated on the southern margin of the active oil
and gas producing areas of the North West Java Basin and includes fields such as
Subang, Jatibarang, Tambun and Pondok Tengah. Consequently the northern margin
of the block is located close to PT Pertamina (Persero)'s well-developed oil and
gas pipeline network. The Citarum PSC was awarded to BPREC on 7 October 2005 and
no wells have yet been drilled in the block. BPREC is a company with the
following shareholdings: Ranhill Energy 60% operator; BPE 20 per cent.; and MEC
20 per cent.. On 21 June 2006 BPREC (acting by its liquidator) entered into a
Deed of Assignment whereby BPREC assigned its 100 per cent. working interest in
the Citarum PSC to BPREC Pte. BPREC Pte. is a company with the following
shareholdings: West Java Energy 60 per cent. operator; BPE 20 per cent.; and MEC
20 per cent.

Bangladesh Block 22 Production Sharing Contract

The Bangladesh production sharing contract (the "Bangladesh PSC") relates to
Block 22 which covers approximately 1,250 km2 in the Chittagong Hills area in
eastern Bangladesh. Block 22 lies to the south of gas producing fields in India
and is to the east of nearby gas discoveries and the producing Sangu field
operated by Cairn energy. The operator of the PSC is Ocean Bangladesh
Corporation ("OBC"). Sound Oil Bangladesh Limited ("SOB") has entered an
agreement with OBC under which OBC will assign to SOB 50 per cent. of its
interest in the PSC. This assignment is subject to the extension of the PSC and
the approval of both the government of Bangladesh and the Bangladesh Oil, Gas
and Mineral Corporation. Sound Oil has entered into an option agreement under
which Sound Oil may be required to acquire SOB for a consideration of 14,634,813
new Sound Oil shares (or cash of US$2.0 million if agreed by both parties). The
exercise price of the option is reduced to 2,195,222 new Sound Oil shares (or
cash of US$0.3 million) if the option is exercised before the assignment of
OBC's interest in the PSC has become effective. Sound Oil may exercise its call
option to acquire SOB at any time in the four months from 19 May 2006 and a put
option may be exercised to require Sound Oil to acquire SOB at any time after
four months have elapsed from the date of the agreement, until 19 May 2086.

Intentions and strategy

The purpose of the Enlarged Group will be the exploration and production of
hydrocarbons, either as a joint venture partner with a direct ownership in a
licence or as a shareholder. The Enlarged Group may be either a non-operating
party or an operator depending on the circumstances. The Enlarged Group intends
to acquire discoveries at the appraisal stage and take the properties to
production. Exploration properties will be acquired which have a potentially
high positive impact on the worth of the company (such as Citarum), but with the
risk mitigated, for example by farm out. Other exploration and production
companies may be acquired which have a strategic fit with the Enlarged Group.
The Enlarged Group will be geographically unrestricted but will focus on Asia
and Africa in the first instance.

The Acquisition

Sound Oil has acquired the entire issued share capital of Mitra in consideration
of the allotment and issue of the Consideration Shares. The Consideration Shares
have been issued credited as fully paid and, in aggregate, represent
approximately 32 per cent. of the Enlarged Share Capital.

The Placing

The Company has raised approximately £10.7 million (net of expenses) through the
Placing at a Placing Price of 7.25p per Ordinary Share. The Placing Shares have
been issued credited as fully paid and, in aggregate, represent approximately 23
per cent. of the Enlarged Share Capital.

The net proceeds of the Placing will be used principally to fund the development
and exploration programmes at Bangkanai and Citarum during the remainder of 2006
and 2007. It is expected that during this period four development wells
(including two re-entry wells) and two exploration wells will be completed at
Bangkanai and one exploration well will be completed at Citarum. The Company
expects production to commence at Bangkanai in 2008 and to fund further
exploration and development work after 2007 at Citarum and potentially in
Bangladesh from trading cash inflows, debt funding, farm-in(s) and/or the issue
of further Ordinary Shares as appropriate in the circumstances.
