                        Recommended cash and share offer

                by Goldman Sachs International ("Goldman Sachs")

                                  on behalf of

                            Amerada Hess Corporation

                                       for

                                    LASMO plc


Summary
o    The  Boards of  Amerada  Hess  Corporation  ("Amerada  Hess") and LASMO plc
     ("LASMO")  announce  that they  have  reached  agreement  on the terms of a
     recommended  cash and share offer for the entire  issued  share  capital of
     LASMO. The Offer will be made by Goldman Sachs on behalf of Amerada Hess.

o    The Offer values each LASMO Share at 180 pence,  based on an exchange  rate
     of US$1.4484 : [Pound  Sterling  Symbol] 1.00 and the NYSE closing price of
     US$62.8125 per Amerada Hess Share on 3 November 2000, the last NYSE dealing
     day  prior  to this  announcement.  Under  the  terms of the  Offer,  LASMO
     shareholders  will receive [Pound Sterling  Symbol] 98.29 in cash and 1 new
     Amerada  Hess Share for every 78.7 LASMO  Shares held  (directly or through
     ADSs).

o    The Offer represents a premium of approximately 28 per cent. to the closing
     mid-market price of a LASMO Share on 3 November 2000, the last London Stock
     Exchange dealing day prior to this announcement.

o    The Offer represents a premium of approximately 33 per cent. to the average
     closing mid-market price of a LASMO Share over the last 6 months.

o    The Offer  values  LASMO's  entire  issued share  capital  (diluted for the
     likely exercise of outstanding  options) at  approximately  [Pound Sterling
     Symbol] 2.4 billion.

o    The  combination  of Amerada Hess and LASMO allows  Amerada Hess to achieve
     its strategic  objective of significant  growth in oil and gas reserves and
     production internationally,  and in future cash flow and profitability.  It
     creates one of the largest global  independent  exploration  and production
     companies,  with a focused  portfolio  and the  necessary  scale to compete
     effectively in the international arena.

o    There will be a loan note alternative in respect of the cash element of the
     Offer (other than for certain overseas shareholders).

o    Amerada Hess has received irrevocable undertakings to accept the Offer from
     Schroder  Investment  Management  Limited and Electrafina  S.A., as well as
     from the Directors of LASMO, in respect of their entire holdings amounting,
     in aggregate,  to 276,604,487 LASMO Shares or approximately 20.58 per cent.
     of the issued share capital of LASMO.

Commenting on the transaction, John Hess, Chairman of Amerada Hess, said:

"We are very excited about this  transaction.  The  acquisition of LASMO expands
our exploration and production business,  strengthens our international  reserve
portfolio  and extends our  production  profile.  It  enhances  our  competitive
position in a  consolidating  industry while being accretive to our estimates of
our earnings and cash flow per share for 2001. The combination will increase our
production  from 374,000 boe per day in 2000 to an expected  582,000 boe per day
in 2001, making Amerada Hess one of the largest global  independent  exploration
and production companies, with the scale to access a broader range of investment
opportunities that meet our financial goals."

Antony Hichens, Chairman of LASMO, said:

"This deal is an attractive  opportunity to realise value for our  shareholders.
Shareholders  overwhelmingly welcomed the share buyback announced earlier in the
year and indicated  their support for LASMO's  strategy to accelerate  corporate
and financial  performance.  Our talks on asset  disposals  with other  industry
players  have led us to the  conclusion  that,  in the current  business and oil
price  environment,  LASMO  faces  highly  favourable  sale  conditions  for its
portfolio.  The Board was unanimous in deciding that a predominantly  cash offer
at these  levels,  including  an  opportunity  to  participate  in the  combined
businesses  of  LASMO  and  Amerada   Hess,   should  be   recommended   to  our
shareholders."

This summary should be read in conjunction with the attached announcement.

The foregoing  statement by John Hess as to financial  accretion is not intended
to mean that  Amerada  Hess  earnings or earnings  per share for any period will
necessarily exceed those of any prior period.

                        Recommended cash and share offer

                         by Goldman Sachs International

                                  on behalf of

                            Amerada Hess Corporation

                                       for

                                    LASMO plc


1.   Introduction
The Boards of Amerada Hess Corporation  ("Amerada Hess") and LASMO plc ("LASMO")
announce that they have reached agreement on the terms of a recommended cash and
share offer for the entire issued and to be issued share capital of LASMO.

Based on Amerada Hess closing  stock price of US$62.8125 on 3 November 2000 (the
last  NYSE  dealing  day prior to this  announcement)  and an  exchange  rate of
US$1.4484 : [Pound  Sterling  Symbol] 1.00, the Offer values each LASMO Share at
180 pence,  and LASMO's issued share capital  (allowing for LASMO's  estimate of
likely dilution by the exercise of outstanding  options) at approximately [Pound
Sterling Symbol] 2.4 billion.  The cash element of the consideration  represents
approximately 125 pence per LASMO Share.

The Offer  represents  a premium of  approximately  28 per cent.  to the closing
mid-market  price of a LASMO Share at the close of business on 3 November  2000,
the last London Stock  Exchange  dealing day prior to this  announcement,  and a
premium of approximately 33 per cent. to the average mid-market closing price of
a LASMO share over the last 6 months.

The cash  consideration  under the Offer will be  financed  from  existing  cash
resources and a bank facility  arranged with Goldman Sachs Credit  Partners L.P.
for the purposes of the Offer.

There will also be a loan note alternative in respect of the cash element of the
Offer (other than for certain overseas shareholders).

The  Directors  of LASMO,  who have been so advised by  Schroder  Salomon  Smith
Barney, consider the terms of the Offer to be fair and reasonable.  In providing
its advice to the  directors of LASMO,  Schroder  Salomon Smith Barney has taken
into account the commercial assessments of the Directors of LASMO.

Accordingly, the Directors of LASMO unanimously recommend all LASMO Shareholders
to accept  the  Offer,  as they  intend to do  themselves  in  respect  of their
aggregate holdings of 325,279 LASMO Shares.

Appendix III contains the definitions used in this announcement.


2.   The Offer
The Offer,  which will be subject to the conditions and further terms set out in
Appendix I and to be set out in the formal offer  document,  will be made on the
following basis:

     for every 78.7 LASMO Shares held        [Pound Sterling Symbol] 98.29 in
                                             cash and 1 new Amerada Hess Share

     for every 78.7 LASMO ADSs (each ADS     [Pound Sterling Symbol] 294.87 in
     representing 3 LASMO Shares)            cash and 3 new Amerada Hess Shares

The Offer  values  each LASMO Share at 180 pence,  based on an exchange  rate of
US$1.4484 : [Pound  Sterling  Symbol]1 and the NYSE closing  price of US$62.8125
per Amerada Hess Share on 3 November  2000, the latest NYSE dealing day prior to
this announcement.

The Offer will result in the issue of up to  approximately  17.1 million Amerada
Hess Shares  (representing  approximately  16.3 per cent. of the ordinary  share
capital of Amerada Hess, as enlarged as a result of the Offer).

The new Amerada Hess Shares  issued to LASMO  shareholders  who accept the Offer
will be  credited  as fully  paid,  will rank pari  passu in all  respects  with
existing  Amerada  Hess Shares and will be entitled to all  dividends  and other
distributions  declared,  made or paid by  reference  to a record date after the
date on which they are issued.  This will not  include  the  dividend of Amerada
Hess  expected to be  declared  in December  2000 and paid on or about 3 January
2001.  The new Amerada  Hess Shares are expected to be  authorised  for listing,
subject to official notice of issuance,  on the New York Stock  Exchange.  It is
not expected that application will be made for the new Amerada Hess Shares to be
admitted to dealings on any other stock exchange.

The number of Amerada Hess Shares which will be issued on full acceptance of the
Offer is expected not to exceed approximately 17.1 million on the basis that, as
at 3 November 2000, LASMO had  1,344,328,323  issued ordinary shares  (including
ADSs, each ADS  representing  three LASMO Shares) and that it is reasonable,  in
LASMO's  opinion,  to expect that a further  3,121,406  new LASMO  Shares may be
issued  during  the  relevant  period as a result of the  exercise  of  options.
Amerada  Hess  reserves  the right,  if LASMO  Shares may be issued in excess of
these amounts,  with the result that Amerada Hess would be obliged to issue more
than 17.18  million  new  Amerada  Hess  Shares  under the Offer or  pursuant to
Section 429 of the  Companies  Act 1985,  to adjust the Offer  consideration  by
reducing rateably the aggregate number of Amerada Hess Shares to be issued under
the Offer. In that event, LASMO shareholders will instead be entitled to receive
cash at a rate of [Pound  Sterling  Symbol]43.37  for each Amerada Hess Share by
which the Offer  consideration is so adjusted.  This represents the NYSE closing
price of an Amerada  Hess Share on 3 November  2000,  the last NYSE  dealing day
prior to this announcement,  translated into sterling at the rate of US$1.4484 :
[Pound Sterling Symbol]1.00.


3.   Background to and reasons for the Offer
Amerada Hess strategy is focused on the continued  expansion of its  exploration
and production  business,  the primary driver of future income growth.  Refining
and  marketing  will play a smaller but more  profitable  role in the  Company's
portfolio.

The acquisition of LASMO, a pure  exploration and production  company,  will add
significantly  to Amerada Hess oil and gas reserves and production  profile.  It
will also create a more balanced  investment  portfolio due to the complementary
nature of their assets, cashflows and investment  opportunities.  Further, given
the significant geographical overlap of both companies, Amerada Hess anticipates
significant synergies.

Amerada  Hess has hedged its foreign  exchange  exposure to lock in the purchase
price of the  transaction  and has hedged  volumes  equivalent to  approximately
one-half of LASMO's  anticipated  2001 oil  production  to support the accretive
nature of the transaction to earnings and cash flow and permit  significant debt
paydown (it being  understood  that this  statement is not intended to mean that
Amerada  Hess  earnings  or earnings  per share for any period will  necessarily
exceed those of any previous period).

Amerada Hess management believes this combination will:

o    continue  the   transformation  of  Amerada  Hess  to  an  exploration  and
     production  company;  exploration  and  production is expected to represent
     approximately  76 per cent. of average capital employed at year end 2001 on
     a pro-forma  basis (compared with 59 per cent. at year end 2000 for Amerada
     Hess on a stand-alone basis);

o    achieve  Amerada Hess  strategic  objective  to increase its  international
     reserves  outside the US and North Sea;  international  proved and probable
     reserves will be increased to 41 per cent. on a pro-forma basis from 16 per
     cent. of total proved and probable reserves at year-end 1999;

o    enhance Amerada Hess production growth from 5 per cent.  pre-acquisition to
     6 per cent. post-acquisition on a compound annual basis through 2004, while
     significantly extending its reserve life from 14.1 to 15.8 years (including
     proved and probable reserves);

o    add high quality  operated  reserves at an  attractive  cost of US$5.49 per
     proved boe;

o    increase reserves per share from 11.3 proved boe per share at year end 1999
     to 17.2 proved boe per share on a pro-forma basis;

o    generate   approximately   US$130  million  of  annual  pre-tax   synergies
     (approximately US$90 million of annual synergies after tax);

o    preserve balance sheet flexibility through the issuance of equity amounting
     to 31 per cent. of the value of the Offer to continue  Amerada Hess ability
     to fund its capital expenditures and its share repurchase programme;

o    be accretive to Amerada Hess  internal  2001 estimate of earnings per share
     and cash flow per share (by 2.5 per cent. and 17.8 per cent.  respectively)
     based on futures  prices (it being  understood  that this  statement is not
     intended to mean that Amerada  Hess  earnings or earnings per share for any
     period will necessarily exceed those of any previous period);

o    increase  Amerada  Hess  production  from  374,000  boe  per day in 2000 to
     582,000 boe per day in 2001 on a pro-forma  basis,  making Amerada Hess one
     of the largest global independent exploration and production companies with
     the scale to access a broader range of investment  opportunities  that meet
     its financial goals.


4.   The Loan Note Alternative
As an alternative to some or all of the cash consideration which would otherwise
be receivable under the Offer,  accepting LASMO Shareholders (other than certain
overseas  shareholders) will be able to elect to receive Loan Notes to be issued
by Amerada Hess on the following basis:

     For every [Pound Sterling Symbol]1        [Pound Sterling Symbol]1 nominal
     of cash consideration under the Offer     value of Loan Notes

The Loan  Notes,  which will be  governed  by  English  law,  will be  unsecured
obligations  of Amerada  Hess and will be issued,  credited  as fully  paid,  in
integral multiples of [Pound Sterling Symbol]1 nominal value. All fractional
entitlements will be disregarded and not paid.

Goldman  Sachs has advised that,  based on market  conditions on 3 November 2000
(the last  business day before this  announcement),  the value of the Loan Notes
(had they been in issue on that day)  would have been not less than 95 pence per
[Pound Sterling Symbol]1 in nominal value.

The Loan Notes will be transferable (subject to certain conditions) in multiples
of [Pound Sterling Symbol]500 or such lower numbers as Amerada Hess may approve,
but no  application  will be made for them to be listed or dealt in on any stock
exchange.

The Loan Notes have not been, and will not be,  registered  under the Securities
Act or under the laws of any State of the United  States and may not be offered,
sold or delivered,  directly or indirectly,  in the United States,  or to or for
the account or benefit of any US person,  except  pursuant to an exemption from,
or in a transaction  not subject to, the  requirements  of the Securities Act or
the relevant  securities laws of any State of the United States.  The Loan Notes
may not be  offered,  sold or  delivered,  directly  or  indirectly,  in or into
Canada, Australia or Japan.

The Loan Notes will bear  interest  (from but excluding the date of issue to the
relevant holder of Loan Notes) payable (subject to any requirement to deduct tax
therefrom)  semi-annually in arrears on 30 June and 31 December in each year, or
(if in any year the relevant date is not a business  day) on the next  following
business day  commencing on 30 June 2001, up to and including 31 December  2005,
at a rate  of 0.5  per  cent.  below  LIBOR  for  six  month  sterling  deposits
determined on the first business day of each interest period. The first interest
payment  will be  made on 30 June  2001  in  respect  of the  period  up to (but
excluding) 30 June 2001.

The Loan Notes will be redeemable at par at the option of the holders,  in whole
or in any part  (being  [Pound  Sterling  Symbol]500  in  nominal  amount or any
integral  multiple  thereof),  on 30 June  2001 and on any  subsequent  interest
payment  date.  If at any time 5 per cent.  or less in nominal value of the Loan
Notes  issued  remain  outstanding,  Amerada  Hess  shall  have the right on any
interest  payment  date  falling  on or after 30 June  2001 to repay  all of the
outstanding Loan Notes at par,  together with accrued  interest.  Any Loan Notes
outstanding  on 31  December  2005 will be redeemed  at par  (together  with any
accrued interest) on that date.

No Loan  Notes  will be  issued  unless,  at the time the  Offer  becomes  or is
declared  unconditional  in all  respects,  valid  elections  for the Loan  Note
Alternative  will  result  in the  issue of at least  [Pound  Sterling  Symbol]2
million  in  aggregate  nominal  value of Loan Notes or such  smaller  amount as
Amerada Hess may decide.  If  insufficient  elections  are  received,  the LASMO
Shareholders  who validly  accept the Offer and elect to receive Loan Notes will
instead receive cash in accordance with the terms of the Offer.

The Loan Note Alternative is conditional on the Offer becoming or being declared
unconditional  in all  respects  and will  remain  open for so long as the Offer
remains  open for  acceptance.  Further  details  of the  terms of the Loan Note
Alternative will be contained in the formal offer document.


5.   Irrevocable Undertakings
Amerada Hess has received irrevocable  undertakings to accept the Offer from the
Directors of LASMO in respect of their entire holdings, amounting, in aggregate,
to 325,279 LASMO Shares  representing 0.02 per cent. of the issued share capital
of LASMO. Such undertakings will cease to be binding only if the Offer lapses or
is withdrawn.

Amerada Hess has also received irrevocable undertakings from Schroder Investment
Management  Limited  and  Electrafina  S.A. to accept the Offer in respect of an
aggregate of approximately 276,279,208 LASMO Shares,  representing approximately
20.56 per cent. of LASMO's issued share capital.  These  undertakings will cease
to be binding if a third  party  makes an offer for the fully  diluted  ordinary
share capital of LASMO the value of which, upon its  announcement,  is more than
10 per cent.  greater  than 180p per LASMO  Share or, if less,  the value of the
Offer per LASMO Share at the close of the NYSE dealing day immediately preceding
announcement of the new offer.

Accordingly,  Amerada Hess has received irrevocable undertakings in respect of a
total  of   approximately   276,604,487   million   LASMO  Shares   representing
approximately 20.58 per cent. of the existing LASMO ordinary share capital.


6.   Information relating to Amerada Hess
Amerada Hess,  headquartered in New York, is a global  integrated energy company
engaged in the exploration for and the production, purchase,  transportation and
sale of crude oil and  natural  gas,  the  refining of crude oil and the sale of
refined  petroleum  products.  Exploration and production  activities take place
primarily in the United States,  the United Kingdom,  Norway,  Denmark,  Brazil,
Algeria, Gabon, Indonesia, Azerbaijan and Thailand.

Amerada Hess produces over 374,000 barrels of oil equivalent per day, two-thirds
oil and one-third natural gas. Amerada Hess total proved oil and gas reserves as
at 31  December  1999 were over 1 billion  boe,  (1.7  billion  boe  proved  and
probable).  Approximately 84 per cent. of its proved and probable  reserves were
located in the United States and the North Sea.

Amerada Hess vision is to deliver  superior  returns while  providing  long-term
profitable  growth.  The acquisition of LASMO furthers  Amerada Hess strategy to
expand its  exploration and production  operations  outside of its core areas of
the United States and the North Sea and increase reserves outside its core areas
to at least one-third of total reserves. Brazil, Venezuela, Africa, Central Asia
and Southeast Asia are all target areas.

Amerada Hess future strategy will involve a balance among  exploration,  reserve
developments  and  reserve  acquisitions.  Amerada  Hess is well  positioned  to
provide  long-term,  profitable  growth  and  withstand  volatile  energy  price
environments as a result of its strong cash flow, reduced cost structure, strong
production  growth and strong balance sheet.  At September 30, 2000 Amerada Hess
total  debt to  capitalisation  ratio was 36 per cent.  and  earnings  were $683
million ($7.57 per share) for the first nine months of the year, higher than any
full year in Amerada Hess history.

Refining and marketing has become a smaller,  more profitable portion of Amerada
Hess portfolio.

Refined  petroleum  products  are  manufactured  at the HOVENSA  refinery in St.
Croix,  United  States  Virgin  Islands,  which is owned jointly by Petroleos de
Venezuela S.A. and Amerada Hess. The refinery is one of the largest in the world
with a capacity of 500,000 barrels per day and a fluid  catalytic  cracking unit
that operates at 140,000 barrels per day.

Amerada Hess markets refined petroleum  products on the East Coast of the United
States.  These refined petroleum  products are marketed through 27 terminals and
approximately  940 HESS brand  retail  outlets.  Amerada  Hess markets fuel oil,
natural gas and  electricity to industrial and commercial  customers on the East
Coast of the United  States.  Amerada  Hess also  markets  natural gas under the
Amerada Hess Gas name to approximately 350,000 customers in the UK.

Retail  marketing is the area of emphasis in Amerada Hess  downstream  business.
Amerada Hess vision is to be the leading independent retail marketer on the East
Coast of the United  States.  Amerada  Hess  expects to have nearly 1,100 retail
outlets  by the end of the first  quarter  of 2001.  Amerada  Hess is focused on
expanding  HESS EXPRESS  convenience  stores at its retail outlets which include
fast food outlets.

For the nine months  ended 30  September,  2000,  Amerada  Hess  reported  total
revenues of $8.5  billion  (1999:  $5.2  billion) and net income of $683 million
(1999: $307 million). Net assets as at 30 September,  2000 were $3.5 billion (31
December 1999: $3.0 billion). For the full year ended December 31, 1999, Amerada
Hess had total revenues of $7.5 billion  (1998:  $6.6 billion) and net income of
$438 million (1998: $(459) million).


7.   Information relating to LASMO
LASMO,  headquartered  in London,  is a substantial  oil and gas exploration and
production   company  whose   activities  and  producing  assets  are  presently
concentrated  primarily in North West Europe and Indonesia,  and these, together
with Venezuela,  North Africa and Pakistan are the current material contributors
to reserves.  At the end of 1999,  LASMO was active in 14  countries  around the
world, in nine of which it acted as operator.  Production during 1999 was mainly
derived  from six of these  countries:  the  United  Kingdom,  The  Netherlands,
Indonesia, Venezuela, Algeria and Pakistan.

As at December 31, 1999,  LASMO's net proved oil and gas reserves were estimated
at 830 million boe.  Approximately  62 per cent.  relate to oil and 38 per cent.
relate to gas, with 24 per cent. of LASMO's net proved reserves located in North
West Europe, 27 per cent. in Indonesia,  29 per cent. in Venezuela, 14 per cent.
in North  Africa and 6 per cent.  in Pakistan.  For the year ended  December 31,
1999, LASMO's average daily production was 178,000 boe with approximately 56 per
cent. derived from North West Europe and approximately 27 per cent. derived from
Indonesia.  In the same  period,  production  of crude oil and  natural gas each
accounted  for  approximately  62 per  cent.  and 38 per cent.  respectively  of
LASMO's daily average production.

For the six months ended 30 June 2000,  LASMO reported sales of [Pound  Sterling
Symbol]463 million (1999:  [Pound Sterling Symbol]216 million) and profit before
exceptional  items and taxation of [Pound  Sterling  Symbol]187  million  (1999:
[Pound Sterling Symbol]35  million).  Net assets as at 30 June, 2000 were [Pound
Sterling  Symbol]1,467  million. For the full year ended 31 December 1999, LASMO
had  sales  of  [Pound  Sterling   Symbol]594  million  (1998:  [Pound  Sterling
Symbol]484  million) and profit before  exceptional items and taxation of [Pound
Sterling Symbol]211 million (1998: [Pound Sterling Symbol]1 million).

8.   Management and employees
The accrued  employment rights of employees of LASMO,  including pension rights,
will be fully safeguarded.  Amerada Hess attaches great importance to the skills
and  experience of the  management and employees of LASMO and believes that they
will benefit from the enhanced opportunities available within Amerada Hess.


9.   LASMO Share Option Schemes
The Offer will  extend to any further  LASMO  Shares  issued or  unconditionally
allotted  while the Offer  remains  open for  acceptance  (or on or before  such
earlier  date as  Amerada  Hess may,  subject to the City Code  and/or  with the
consent of the Panel, decide) including those issued as a result of the exercise
of options granted under the LASMO Share Option Schemes.

It is  intended  that  appropriate  proposals  will be  available  to holders of
options  under the LASMO  Share  Option  Schemes  once the Offer  becomes  or is
declared unconditional in all respects.


10.  Disclosure of interests in LASMO
Subject as mentioned  below,  and except for the  interests of the  Directors of
LASMO referred to in this announcement, neither Amerada Hess nor any director of
Amerada Hess or LASMO,  nor so far as Amerada Hess is aware any person acting in
concert with Amerada Hess, owns or controls any LASMO Shares or holds any option
to acquire any LASMO Shares or has entered  into any  derivative  referenced  to
LASMO Shares which remains outstanding.

In view of the  requirements  for  confidentiality,  Amerada  Hess  has not made
enquiries in this  respect of certain  parties who may be deemed by the Panel to
be acting in concert with it for the purposes of the Offer.  These  details will
be obtained as soon as possible.


11.  General
Appendix III contains definitions of the terms used in this announcement.

The  timetable  for the Offer will be as  approved by the Panel but will also be
subject to certain requirements of the SEC. Further details will be contained in
the offer document  setting out full details of the Offer to be published in due
course.

Amerada  Hess and LASMO have  entered  into an  agreement  as an  inducement  to
Amerada Hess to make the Offer.  Under this  agreement,  LASMO has agreed not to
solicit a  takeover  offer  from any  third  party  and to pay  [Pound  Sterling
Symbol]24  million  to  Amerada  Hess if,  inter  alia,  the Offer  lapses or is
withdrawn  following  an  announcement,  made  during the Offer  period,  of any
proposal  involving  a  change  of  control  of  LASMO  by a third  party or any
acquisition  or  disposal  of assets  with a value in excess of [Pound  Sterling
Symbol]100  million  which,  in either case, is completed at any time in 2001 or
if, while the Offer remains  open,  the Directors of LASMO cease to recommend it
or qualify  their  recommendation  or LASMO takes  action  which will  prevent a
condition to the Offer from being  fulfilled in a material  way.  LASMO has also
agreed  with  Amerada  Hess that  during the Offer it will not grant any further
subscription  rights in respect of new LASMO  Shares and will not allot or issue
new LASMO Shares, except insofar as required under previously granted options or
other rights to acquire LASMO Shares which cannot be satisfied by the payment of
cash or the transfer of existing issued shares.

Amerada  Hess  will  explore  the  possibility  of  introducing  a mix and match
alternative  which will enable LASMO  shareholders  to vary the  proportions  in
which they  receive  Amerada Hess Shares and cash under the Offer if this can be
done  consistently  with the legislation  applicable to the Offer and on a basis
acceptable to Amerada Hess.

The  Offer,  including  the Loan Note  Alternative,  will not be made in or into
Canada,  Australia  or Japan  unless,  at its  discretion,  Amerada Hess decides
otherwise   having  satisfied  itself  with  respect  to  the  applicable  legal
requirements  in those  jurisdictions.  The Offer is not being made in the US by
means of this announcement.

The  availability  of the Offer to persons  who are not  resident  in the United
Kingdom  or the  United  States  may be  affected  by the  laws of the  relevant
jurisdictions.  Persons who are not resident in the United Kingdom or the United
States should inform themselves about and observe any applicable requirements.

All LASMO  Shares  which are  acquired  by Amerada  Hess under the Offer will be
acquired  fully  paid and free  from all  liens,  equities,  charges,  equitable
interests,  encumbrances and other interests and together with all rights now or
hereafter  attaching  thereto,  including  the right to  receive  and retain all
dividends and other  distributions  declared,  made or payable after the date of
this announcement.

In so far as a dividend or other  distribution was proposed,  declared,  made or
payable in respect  of a LASMO  Share as at 3 November  2000 but had not by then
been paid, or is  subsequently  proposed,  declared,  made or payable,  the cash
payable  under the Offer in respect  of that LASMO  Share will be reduced by the
amount of the dividend and/or  distribution  except in so far as the LASMO Share
is or will be transferred under the Offer on a basis which entitles Amerada Hess
to receive the dividend or  distribution  directly  from LASMO and to retain it.
The amount of any  dividend or  distribution  which  Amerada Hess is entitled to
recover from a LASMO  Shareholder in respect of a LASMO Share will be reduced by
the amount of any such reduction of the consideration payable in respect of that
LASMO Share  pursuant to the Offer.  To the extent  that such  reduction  of the
consideration  is permitted  but is not made,  the person to whom the  unreduced
Offer price is paid will be obliged to account to Amerada Hess for the amount of
the dividend or distribution.

Fractions  of new  Amerada  Hess  Shares  will not be  allocated  or  issued  to
accepting LASMO  Shareholders.  Fractional  entitlements to the new Amerada Hess
Shares will be  aggregated  and sold in the market and the net  proceeds of sale
distributed  pro rata to the  holders of LASMO  Shares  entitled  to them.  Such
payment will be made in sterling,  the proceeds  having been  converted  from US
dollars at a prevailing  exchange  rate selected by Amerada Hess at the relevant
time. However,  individual  entitlements to amounts of less than [Pound Sterling
Symbol]5.00 will not be paid to holders of LASMO Shares but will be retained for
the benefit of the enlarged Amerada Hess group.

          (taken as a whole) in a manner which is material and adverse;

     and all  applicable  waiting and other time  periods  during which any such

(if capable of waiver)  waived by 3.00pm on the first  closing date of the Offer
or such later time and/or date as Amerada Hess may determine in accordance  with
the City Code or with the consent of the Panel and  subject to any  requirements
of the laws of the US.

Amerada  Hess  reserves the right to waive,  in whole or in part,  all or any of
conditions  (c) to (m)  inclusive.  Amerada Hess shall be under no obligation to
waive or treat as satisfied  any of  conditions  (a) to (m)  inclusive by a date
earlier than the latest date for its satisfaction notwithstanding that any other

in respect of any aspect of such  acquisition  to a competent  authority  of the
United  Kingdom  under  Article  9(1) of the  Regulation  which is followed by a
reference of the proposed acquisition to the Competition Commission, in any such
case before 3.00p.m. on the first closing date of the Offer or the date when the
Offer is declared or becomes  unconditional as to acceptances,  whichever is the
later.  In those  circumstances,  the Offer  will cease to be capable of further
acceptances  and persons  who have  accepted it will no longer be bound by their
acceptances.

The attention of member firms of the New York Stock Exchange is drawn to certain
UK dealing disclosure  requirements following the announcement of the Offer. The
announcement  commenced  an offer  period under the City Code which is published
and administered by the Takeover Panel. An offer period is deemed to commence at
the time when an announcement  is made of a proposed or possible offer,  with or
without terms.

The  above  disclosure  requirements  are  set  out in  Rule 8 of the  Code.  In
particular,  Rule 8.3 requires  public  disclosure  of dealings  during an offer
period  by  persons  who  own  or  control,  or who  would  as a  result  of any
transaction  own or  control,  1 per  cent.  or more of any  class  of  relevant
securities of the offeror or offeree company.  Relevant  securities includes all
instruments  exchangeable  into LASMO Shares or into  Amerada Hess Shares.  This
requirement  will apply until the first closing date of the Offer or, if this is
later,  the date when the  Offer  becomes  or is  declared  unconditional  as to
acceptances.

Disclosure  should be made on the appropriate form before 12 noon London time on
the  business  day  following  the  date  of  the  dealing  transaction.   These
disclosures  should be sent to the  Company  Announcements  Office of the London
Stock Exchange.

Member  firms  advise  those of their  clients who wish to deal in the  relevant
securities  of LASMO,  whether in the US or the UK, that they may be affected by
these  requirements.  If there is any doubt as to their  application,  the Panel
should  be  consulted   (telephone   number   +44-(0)20-7382-9026,   fax  number

                                Sources and Bases

Save as otherwise set out in this  announcement,  the following  constitute  the
bases and sources of information referred to in this document.

1.   The  market  value of an Amerada  Hess  Share is based on the NYSE  closing
     price of $62.8125 on 3 November  2000,  the last NYSE  dealing day prior to
     the date of this announcement.

2.   The value of LASMO's issued share capital  (diluted for likely  exercise of
     outstanding  options) is based upon 1,344,328,323 issued LASMO Shares and a
     further  3,121,406  new  LASMO  Shares  which  in  LASMO's  opinion  it  is
     reasonable to expect may be issued in the relevant  period  pursuant to the
     exercise of options.

3.   The  premium of the Offer  value per LASMO  Share over the price of a LASMO
     Share on 3  November  2000 is  calculated  using the value of the Offer per
     LASMO Share and the closing mid-market price of a LASMO Share on that date.

4.   The premium of the offer value per LASMO Share over the average  mid-market
     closing  price  of  a  LASMO  Share  over  the  6  months   preceding  this
     announcement  is based on the average of the closing  mid-market  prices on
     each  London  Stock  Exchange  dealing  day over  the 6 months  immediately
     preceding (and including) 3 November 2000.

5.   All currency  conversions  between pounds sterling and US dollars have been
     made at an exchange rate of US$1.4484 : [Pound Sterling Symbol]1.00,  which
     was the noon  buying  rate in The City of New York for cable  transfers  in
     pounds  sterling as certified for customs  purposes by the Federal  Reserve
     Bank of New York on 3 November 2000 (unless expressly stated otherwise).

and a bank facility arranged with Goldman Sachs International.

     Under the terms of the offer, for every 78.7 LASMO shares held (directly or
through  American  Depositary  Shares) LASMO  shareholders  will receive  [Pound
Sterling  Symbol]98.29  in cash  and 1  share  of  Amerada  Hess  Common  Stock,
constituting  approximately 69% cash and 31% equity. The offer values each LASMO
share at 180  pence,  based on an  exchange  rate of  $1.4484 : [Pound  Sterling
Symbol]1  and the NYSE  closing  price of  $62.8125  per  Amerada  Hess share on
November  3, 2000,  the last NYSE  trading day prior to this  announcement.  The
offer represents a premium of approximately 28% to the mid-market  closing price
of a LASMO share at the close of business on November 3, 2000,  the last trading
day on the London Stock Exchange prior to this  announcement.  The offer will be
made through Goldman Sachs International on behalf of Amerada Hess in the United
Kingdom.

     Amerada Hess and LASMO have  entered  into an  agreement  under which LASMO
will pay Amerada Hess [Pound Sterling  Symbol]24  million if the offer lapses or
is withdrawn  following an  announcement  of any proposal  involving a change of
control  of LASMO by a third  party or a major  asset  disposal  or  acquisition
which,  in either case,  is completed at any time in 2001 or if, while the offer
remains  open,  the  Board of  Directors  of LASMO  ceases  to  recommend  it or
qualifies its recommendation.

     Amerada Hess has received irrevocable undertakings to accept the offer from
Schroder Investment  Management Limited and Electrafina S.A. as well as from the
Directors of LASMO in respect of their  holdings,  amounting in the aggregate to
approximately 20% of LASMO's issued share capital.

     Commenting on the transaction, John Hess, Chairman of Amerada Hess, said:

     "We are very  excited  about this  transaction.  The  acquisition  of LASMO
     expands  our   exploration   and  production   business,   strengthens  our
     international  reserve  portfolio and extends our  production  profile.  It
     enhances our competitive  position in a consolidating  industry while being
     accretive  to our  estimates  of our  earnings  and cash flow per share for
     2001. The combination will increase our production from 374,000 boe per day
     in 2000 to an expected 582,000 boe per day in 2001, making Amerada Hess one
     of the largest global independent exploration and production companies with
     the scale to access a broader range of investment  opportunities  that meet
     our financial goals."

     Background to and reasons for the offer

     Amerada  Hess'  strategy  is  focused  on the  continued  expansion  of its
exploration and production business, the primary driver of future income growth.

     The acquisition of LASMO, a pure exploration and production  company,  will
add significantly to Amerada Hess' oil and gas reserves and production  profile.
It  will  also  create  a  more  balanced   investment   portfolio  due  to  the
complementary  nature of their assets,  cashflows and investment  opportunities.
Further, given the significant  geographical overlap of both companies,  Amerada
Hess  anticipates  significant  synergies.  Amerada  Hess has hedged its foreign
exchange  exposure  to lock in the  purchase  price of the  transaction  and has
hedged volumes equivalent to approximately  one-half of Lasmo's 2001 anticipated
oil  production to support the accretive  nature of the  transaction to earnings
and cash flow and permit significant debt paydown (it being understood that this
statement is not intended to mean that  Amerada  Hess'  earnings or earnings per
share for any period will necessarily exceed those of any previous period).

     Amerada Hess management believes that this combination will:

o    Continue  the   transformation  of  Amerada  Hess  to  an  exploration  and
     production  company;  exploration  and  production is expected to represent
     approximately  76% of  average  capital  employed  at  year  end  2001 on a
     pro-forma  basis (compared with 59% for Amerada Hess for year-end 2000 on a
     stand-alone basis);

o    Achieve  Amerada Hess'  strategic  objective to increase its  international
     reserves outside the United States and the North Sea;  international proved
     and probable  reserves  will be increased to 41% on a pro-forma  basis from
     16% of total proved and probable reserves at year-end 1999;

o    Enhance  Amerada  Hess'  production  growth from 5%  pre-acquisition  to 6%
     post-acquisition   on  a  compound   annual  basis  through   2004,   while
     significantly extending its reserve life from 14.1 to 15.8 years (including
     proved and probable reserves);

o    Add high  quality  operated  reserves  at an  attractive  cost of $5.49 per
     proved boe;

o    Increase reserves per share from 11.3 proved boe per share at year-end 1999
     to 17.2 proved boe per share on a pro-forma basis;

o    Generate   approximately   $130   million  of  annual   pre-tax   synergies
     (approximately $90 million of annual synergies after-tax);

o    Preserve balance sheet flexibility through the issuance of equity amounting
     to 31% of the value of the offer to continue  Amerada Hess' ability to fund
     its capital expenditures and its share repurchase program;

o    Be accretive to Amerada  Hess'  internal 2001 estimate of earnings and cash
     flow per share (by 2.5% and 17.8% respectively) based on futures prices (it
     being  understood  that this statement is not intended to mean that Amerada
     Hess' earnings or earnings per share for any period will necessarily exceed
     those of any previous period); and

o    Increase  Amerada  Hess'  production  from  374,000  boe per day in 2000 to
     582,000 boe per day in 2001 on a pro-forma  basis,  making Amerada Hess one
     of the largest global independent exploration and production companies with
     the scale to access a broader range of investment  opportunities  that meet
     its financial goals.

     Information relating to Amerada Hess

     Amerada  Hess,  headquartered  in New York, is a global  integrated  energy
company  engaged  in  the   exploration   for  and  the  production,   purchase,
transportation  and sale of crude oil and natural gas, the refining of crude oil
and  the  sale  of  refined  petroleum  products.   Exploration  and  production
activities  take place  primarily  in the  United  States,  the United  Kingdom,
Norway, Denmark, Brazil, Algeria, Gabon, Indonesia, Azerbaijan and Thailand.

     Amerada Hess  produces  over  374,000  barrels of oil  equivalent  per day,
two-thirds oil and one-third natural gas. Amerada Hess' total proved oil and gas
reserves as at 31 December  1999 were over 1 billion boe (1.7 billion boe proved
and  probable).  Approximately  84% of its proved  and  probable  reserves  were
located  in the  United  States  and the North  Sea.  The  acquisition  of LASMO
furthers  Amerada  Hess'  strategy  to expand  its  exploration  and  production
operations outside of its core areas of the United States and the North Sea.

     Amerada Hess' future  exploration  and  production  strategy will involve a
balance  among  exploration,  reserve  developments  and  reserve  acquisitions.
Amerada Hess is well  positioned  to provide  long-term,  profitable  growth and
withstand  volatile  energy  price  environments  as a result of its strong cash
flow, reduced cost structure and strong production growth. At September 30, 2000
Amerada Hess' total debt to capitalization ratio was 36 % and earnings were $683
million ($7.57 per share) for the first nine months of the year, higher than any
full year in Amerada Hess' history.

     Refining and marketing  has become a smaller,  more  profitable  portion of
Amerada Hess'  portfolio.  Refined  petroleum  products are  manufactured at the
HOVENSA  refinery in St. Croix,  United States  Virgin  Islands,  which is owned
jointly by Petroleos de Venezuela  S.A. and Amerada Hess. The refinery is one of
the largest in the world with a capacity of 500,000  barrels per day and a fluid
catalytic cracking unit that operates at 140,000 barrels per day.

     Amerada Hess markets  refined  petroleum  products on the East Coast of the
United  States.  These  refined  petroleum  products  are  marketed  through  27
terminals and approximately 940 HESS brand retail outlets.  Amerada Hess markets
fuel oil, natural gas and electricity to industrial and commercial  customers on
the East Coast of the United States.

     Retail  marketing  is the  area of  emphasis  in  Amerada  Hess  downstream
business.  Amerada Hess' vision is to be the leading independent retail marketer
on the East Coast of the United  States.  Amerada  Hess  expects to have  nearly
1,100 HESS retail outlets by the end of the first quarter of 2001.  Amerada Hess
is focused on expanding  HESS EXPRESS  convenience  stores at its retail outlets
which include fast food outlets.

     For the nine months ended 30 September,  2000,  Amerada Hess reported total
revenues of $8.5  billion  (1999:  $5.2  billion) and net income of $683 million
(1999: $307 million). Net assets as at 30 September,  2000 were $3.5 billion (31
December 1999: $3.0 billion). For the full year ended December 31, 1999, Amerada
Hess had total revenues of $7.5 billion  (1998:  $6.6 billion) and net income of
$438 million (1998: $(459) million).
