On 23 July 1999 American Rivers Oil Company ('AROC') and Alliance Resources PLC
('Alliance') announced that they had entered into a preliminary agreement
under which, subject to the satisfaction of various pre-conditions, AROC would
make a recommended share for share offer for Alliance. The announcement stated
that if an offer for Alliance were made by AROC, it would comply with the City
Code on Takeovers and Mergers.

Over the past few years, as a consequence of the various transactions approved
by  shareholders, the central management of Alliance has moved from the United
Kingdom to the USA. Following discussions with the Panel on Takeovers and
Mergers, Alliance has established that, because of this move of central
management, the City Code on Takeovers and Mergers no longer applies to it.

If AROC makes an offer for Alliance, AROC will be filing, and circulating to
shareholders of Alliance, a registration statement which complies with US
securities legislation, in relation both to its offer for Alliance shares and
the corresponding issue of shares in AROC in exchange for Alliance shares. In
the circumstances, AROC has indicated that such an offer would not be subject to
the requirements of the City Code on Takeovers and Mergers.
