                              Sterling Energy plc


          Extension of Offer and announcement of level of acceptances



Sterling Energy plc announces that the Offer made by Evolution Beeson Gregory on
behalf of Sterling for the issued and to be issued share capital of Fusion Oil &
Gas plc, including the Partial Cash Alternative and Additional Cash Election as
set out in the offer document dated 1 October 2003, has been extended until 3.00
p.m. on 5 November 2003.


As at 3.00 pm yesterday, 22 October 2003, being the first closing date of the
Offer, Sterling either owned or had received valid acceptances for the Offer in
respect of an aggregate of 46,682,594 Fusion Shares, representing approximately
47.54 per cent. of the issued ordinary share capital of Fusion.


Of this total, Sterling had received valid acceptances for the Offer in respect
of holders of 26,682,383 Fusion Shares, representing approximately 27.17 per
cent. of the issued ordinary share capital of Fusion. These acceptances include
valid acceptances of the Offer in respect of 9,400,000 Fusion Shares held by
Invesco Asset Management Limited for which Sterling had received an irrevocable
undertaking to accept the Offer and 11,367,500 Fusion Shares for which Sterling
had received letters of intent to accept the Offer, representing approximately
9.5 per cent. and 11.6 per cent. respectively of Fusion's issued ordinary share
capital.


Prior to the announcement of the Offer Sterling acquired 20,000,000 Fusion
Shares representing approximately 20.4 per cent. of the issued ordinary share
capital of Fusion in addition to the 211 Fusion Shares it already owned.


Of those Fusion Shareholders accepting the Offer to date, 99.3 per cent. have
elected to receive wholly Sterling Shares on the basis of 3.5 Sterling Shares
for each Fusion Share rather than electing for the Partial Cash Alternative or
the Additional Cash Election available under the terms of the Offer.


Despite the continued reluctance of the board of Fusion to recognise the merits
of the Offer, Sterling is delighted by the strong support that the Offer has
received to date.


Fusion Shareholders are reminded that the Sterling offer is the only alternative
currently available to them. Fusion Shareholders are urged to follow the lead of
Fusion's largest institutional shareholders who have already accepted the Offer
by returning their Form of Acceptance as soon as possible.


Words and expressions defined in the offer document from Sterling to Fusion
Shareholders dated 1 October 2003 and the circular from Sterling to Fusion
Shareholders dated 18 October 2003 shall have the same meaning in this
announcement.


Evolution Beeson Gregory, which is regulated in the UK by the Financial Services
Authority, is acting exclusively for Sterling and no one else in connection with
the Offer and other matters described herein and will not be responsible to
anyone other than Sterling for providing the protections afforded to customers
of Evolution Beeson Gregory or for giving advice in relation to the Offer or any
