PRESS RELEASE
NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION

FOR IMMEDIATE RELEASE 4 October 1995
ARAN'S "INDEPENDENT" VALUATION FAILS-- STRATEGIC ALLIANCE NEXT CARD IN PACK?
Aran published yesterday a valuation of its assets which ARCO described as
straining credibility and said should be dismissed. In the market, Aran's
share price showed a rise of just 2%.
ARCO has noted today's press comment that Aran has intimated that it may seek
a strategic alliance with an oil major should ARCO's Offer fail. This
contrasts with its stated wish to remain independent and its claims to have
the technical and financial resources to carry out its exploration and
development plans. Shareholders should ask why Aran is raising the issue of a
strategic alliance at this stage. If the Connemara joint venture is anything
to go by, shareholders should be concerned at the prospect. Under the terms of
the proposed joint venture Statoil has in effect been granted an exclusive six
months option to review Aran's data on Connemara before deciding whether or
not to incur any material amount of the estimated $18.6 million work
programme.
SOURCES:
(1) The statement "Aran has attributed to this undeveloped field
[Schiehallion] a value per barrel more than 25% higher than has been paid
on average in 1995 for barrels which are actually in production in the UK
North Sea" made in ARCO's announcement of 3 October 1995 is based on the
table of asset deals in 1995 published by Wood Mackenzie in August 1995.
(2) The statement that Aran's share price rose by just 2% is based on a
closing mid market price of Stg 65.62p per Aran share on 2 October 1995
and of Stg 66.87p per Aran share on 3 October 1995, as derived from SEAQ
International.
