To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

     Amerada Hess Corporation (the "Offeror") is offering to purchase, upon the
terms and subject to the conditions set forth in the Offer Document dated
December     , 2000 (the "Offer Document") and the related Letter of Transmittal
and Form of Acceptance (which, as amended or supplemented from time to time,
together constitute the "Offer"), (i) all issued and to be issued ordinary
shares of 25p each of LASMO ("LASMO Shares") for L98.29 in cash and 1 new share
of the Offeror for every 78.7 LASMO Shares and (ii) all American Depositary
Shares of LASMO ("LASMO ADSs"), each representing 3 LASMO Shares and evidenced
by American Depositary Receipts ("LASMO ADRs"), for L294.87 in cash and 3 new
shares of the Offeror for every 78.7 LASMO ADSs. LASMO Shares and LASMO ADSs are
referred to collectively as "LASMO Securities".

     Holders of LASMO Securities who validly accept the Offer may elect to vary
the proportions in which they receive shares of the Offeror and cash (the "Mix
and Match Election"). The Mix and Match Election will remain open until 3:00
p.m. (London time), 10:00 a.m. (New York time) on           , 2001. The maximum
number of new Offeror shares to be issued under the Offer and the maximum amount
of cash to be paid under the Offer will not be varied as a result of the Mix and
Match Election. Accordingly, the ability of holders of LASMO Securities to make
a Mix and Match Election will depend on the extent to which other holders of
LASMO Securities make opposite elections. Other relevant terms of the Mix and
Match Election are set out in paragraph 5 of Part B of Appendix I of the Offer
Document.

     For your information and for forwarding to those of your clients for whom
you hold LASMO ADSs registered in your name or in the name of your nominee, we
are enclosing the following documents:
