    pursuant to Rule 457(f)(1) and (3) and Rule 457(c) of the Securities Act of

    translated into U.S. dollars at the noon buying rate on such date of $1.4228

                             IMPORTANT INFORMATION

Goldman Sachs International, which is regulated in the United Kingdom by The
Securities and Futures Authority Limited, is acting for Amerada Hess and no one
else in connection with the Offer and will not be responsible to anyone other
than Amerada Hess for providing the protections afforded to customers of Goldman
Sachs International nor for giving advice in relation to the Offer. Amerada Hess
is making the Offer in the United States on its own behalf.

Schroder Salomon Smith Barney, which is regulated in the United Kingdom by The
Securities and Futures Authority Limited, is acting for LASMO and no one else in
connection with the Offer and will not be responsible to anyone other than LASMO
for providing the protections afforded to customers of Schroder Salomon Smith
Barney nor for giving advice in relation to the Offer.

CERTAIN DEFINITIONS

Certain words and terms used in this document are defined in Appendix IX to this
document.

APPLICABLE DISCLOSURE REQUIREMENTS

The Offer is being made for securities of an English company and the Offer is
subject to English and US securities laws, regulations and requirements. US
investors should be aware that this document has been prepared primarily in
accordance with UK format and style, which differs from US format and style for
documents of this type. In particular, the Appendices to this document contain
information concerning the Offer (to satisfy US disclosure requirements) which
may be material and which is not summarised elsewhere. In addition, the
financial statements of the LASMO Group in this document have been prepared in
accordance with UK GAAP, and therefore these financial statements may not be
comparable to the financial statements of US companies. A reconciliation between
UK GAAP and US GAAP in respect of certain information contained in this document
is contained in certain documents of the LASMO Group incorporated by reference
herein.

FORWARD-LOOKING STATEMENTS

This Offer Document contains certain statements that are neither reported
financial results nor other historical information. These statements are
forward-looking statements within the meaning of the safe-harbour provisions of
the US federal securities laws. These forward-looking statements are subject to
risks and uncertainties that could cause actual results to differ materially
from those expressed in the forward-looking statements. Many of these risks and
uncertainties relate to factors that are beyond the companies' ability to
control or estimate precisely, such as future market conditions, the behaviour
of other market participants and the actions of governmental regulators. These
and other risk factors are detailed in the two companies' SEC reports. Readers
are cautioned not to place undue reliance on these forward-looking statements,
which speak only as of the date of this Offer Document. The companies do not
undertake any obligation to publicly release any revisions to these
forward-looking statements to reflect events or circumstances after the date of
this announcement.

THE ACCEPTANCE CONDITION

The Offer is conditional on, among other things, valid acceptances being
received (and not, where permitted, withdrawn) by not later than 3.00 pm (London
time), 10.00 am (New York City time), on   --  2000 (or such later time(s)
and/or dates(s) as Amerada Hess may, subject to the rules of the City Code or
with the consent of the Panel, and in accordance with the Exchange Act, decide)
in respect of not less than 90 per cent. (or such lesser percentage as Amerada
Hess may decide) in nominal value of the LASMO Shares (including LASMO Shares
represented by LASMO ADSs) to which the Offer relates, provided that this
Condition (the Acceptance Condition) will not be satisfied unless Amerada Hess
(together with any of its wholly-owned subsidiaries and, to the extent that
Amerada Hess so elects with the consent of the Panel, Methodplan) shall have
acquired or agreed to acquire, whether pursuant to the Offer or otherwise, LASMO
Shares (including LASMO Shares represented by LASMO ADSs) carrying, in
aggregate, more than 50 per cent. of the voting rights then exercisable at
general meetings of LASMO (excluding, to the extent that Amerada Hess so elects
with the consent of the Panel, voting rights attached to the Methodplan Shares).
The Acceptance Condition shall be capable of being satisfied or being treated as
satisfied only at a time when all of the other Conditions shall have been
satisfied, fulfilled or, to the extent permitted, waived, unless Amerada Hess,
with the consent of the Panel, shall otherwise decide.

Amerada Hess reserves the right, subject to the consent of the Panel, to extend
the time allowed under the rules of the City Code for satisfaction of the
Acceptance Condition and accordingly for the satisfaction, fulfilment or, where
permitted, waiver of the other Conditions, and thus to extend the duration of
the Initial Offer Period. Amerada Hess also reserves the right to reduce the
percentage of LASMO Shares (including LASMO Shares represented by LASMO ADSs)
required to satisfy the Acceptance Condition at some time prior to all the
Conditions being satisfied, fulfilled or, to the extent permitted, waived. At
least five business days prior to any such reduction, Amerada Hess will announce
that it has reserved the right so to reduce the Acceptance Condition. The
announcement will be made through a press release designed to inform LASMO
Securityholders in the United Kingdom and elsewhere, and by placing an
advertisement in a newspaper of national circulation in the United States. Such
announcement will state the exact percentage to which the Acceptance Condition
may be reduced, will state that such a reduction is possible but that Amerada
Hess need not declare its actual intentions until it is required to do so under
the City Code and will contain language advising LASMO Securityholders to
withdraw their LASMO Securities if their willingness to accept the Offer would
be affected by a reduction of the Acceptance Condition. Amerada Hess will not
make such an announcement unless it believes that there is a significant
possibility that a sufficient number of acceptances will be received to permit
the Acceptance Condition to be satisfied at such reduced level and that the
other Conditions will be satisfied, fulfilled or, to the extent permitted,
waived at such time (which in any event will not be on a date other than the
Closing Date at the end of the Initial Offer Period). LASMO Securityholders who
are not willing to accept the Offer if the Acceptance Condition is reduced to a
level lower than 90 per cent. should either not accept the Offer until the
Acceptance Condition is satisfied (which may be at a level lower than 90 per
cent.) or be prepared to withdraw their acceptances promptly following an
announcement by Amerada Hess of its reservation of the right to reduce the
Acceptance Condition. Upon any announcement being made that the percentage of
LASMO Shares (including LASMO Shares represented by LASMO ADSs) required to
satisfy the Acceptance Condition may be reduced, the Offer shall not be capable
of becoming or being declared unconditional in all respects until the expiry of
at least five business days thereafter. LASMO Securityholders will be able to
accept the Offer for at least five business days after a reduction of the
Acceptance Condition either during the Initial Offer Period or the Subsequent
Offer Period.

The LASMO Shares held by Methodplan may not be voted by Methodplan as a result
of the operation of section 23 of the Companies Act. Amerada Hess has elected
and has received the consent of the Panel in respect of such election, in
accordance with the terms of the Acceptance Condition, that any LASMO Shares
held by Methodplan at the date the Acceptance Condition is treated as satisfied
will not be counted for the purposes of the Acceptance Condition in determining
(a) whether or not Amerada Hess and/or any other relevant person has acquired or
agreed to acquire, whether pursuant to the Offer or otherwise, LASMO Shares
(including LASMO Shares represented by LASMO ADSs) carrying in aggregate more
than

                                        2
<PAGE>   5

50 per cent. of the voting rights then exercisable at general meetings of LASMO
or (b) the LASMO Shares (including LASMO Shares represented by LASMO ADSs) of
which LASMO (or any other relevant person) is required to acquire (or agree to
acquire) such percentage. This election will not otherwise affect the
determination, for the purposes of the Acceptance Condition, of whether valid
acceptances have been received in respect of not less than 90 per cent. (or such
lesser percentage as Amerada Hess may decide) in nominal value of the LASMO
Shares (including LASMO Shares represented by LASMO ADSs) to which the Offer
relates.

OFFER IN THE UNITED STATES

                            AMERADA HESS CORPORATION
                      RECOMMENDED CASH AND SHARE OFFER FOR
                                   LASMO PLC

Dear Sir or Madam,

On 6 November 2000, it was announced that the boards of LASMO and Amerada Hess
had reached agreement on the terms of a recommended Offer for the entire issued
and to be issued share capital of LASMO. We are extremely pleased at the
prospect of combining our two companies. The purpose of this letter is to
explain the Offer and our reasons for making it and to urge you to accept it.

BENEFITS OF THE OFFER

We are very excited about this transaction. The combined companies will benefit
from an expanded exploration and production business, a strengthened
international reserve portfolio and an extended production profile. The
combination of LASMO and Amerada Hess will enhance our competitive position in a
consolidating industry. It will increase our production from an estimated
374,000 boe per day in 2000 to an expected 582,000 boe per day in 2001, creating
one of the largest global independent exploration and production companies, with
the necessary scale to compete effectively in the international arena.

THE OFFER

Under the terms of the Offer, which has been unanimously approved by the boards
of directors of Amerada Hess and LASMO, each LASMO Securityholder will receive:

<TABLE>
<S>                                                    <C>
FOR EVERY 78.7 LASMO SHARES HELD                       L98.29 IN CASH AND 1 NEW AMERADA HESS SHARE
FOR EVERY 78.7 LASMO ADSS HELD                         L294.87 IN CASH AND 3 NEW AMERADA HESS SHARES
  (EACH ADS REPRESENTING 3 LASMO SHARES)
</TABLE>

At the time of the Announcement, the Offer valued each LASMO Share at 180 pence,
based on an exchange rate of US$1.4484: L1.00 and the NYSE Closing Price of
US$62 13/16 per Amerada Hess Share on 3 November 2000, the last NYSE trading day
prior to the Announcement.

The Offer now values each LASMO Share at    --   pence, based on an exchange
rate of US$   --   :L1.00 and the NYSE Closing Price of US$   --   per Amerada
Hess Share on  -- December 2000, the last NYSE trading day prior to the posting
of this document.

REASONS TO ACCEPT THE OFFER

We believe the Offer affords a very attractive opportunity for LASMO
Securityholders. The Offer:

     -  provides for payment of 69 per cent. of the offer price in cash
        (approximately L1.25 per LASMO Share), but with a 31 per cent. equity
        component that will enable LASMO Securityholders to continue to
        participate at a favourable entry price in a strategically strengthened
        combined enterprise, with significantly greater cash flow and reserves
        per share; and

                                        5
<PAGE>   8

     -  represented, at the time of the Announcement, a premium of approximately
        28 per cent. to the Closing Price of a LASMO Share on 3 November 2000,
        the last London Stock Exchange dealing day prior to the Announcement,
        and a premium of approximately 33 per cent. to the average Closing Price
        of a LASMO Share over the 6 months prior to the Announcement.

We have already received irrevocable undertakings to accept the Offer from two
major shareholders, Schroder Investment Management Limited and Electrafina S.A.,
as well as from the directors of LASMO, constituting in the aggregate 20.1 per
cent. of the total issued LASMO Shares.

On behalf of the board of directors of Amerada Hess, I urge you to accept the
Offer. We welcome you as shareholders of Amerada Hess and invite you to
participate in the increased shareholder value we believe this combination will
create.

                                Yours sincerely,

                                  John B. Hess

                      RECOMMENDED CASH AND SHARE OFFER FOR
                                   LASMO PLC

Dear Sir or Madam,

1.  INTRODUCTION

It was announced on 6 November 2000 that your board and the board of Amerada
Hess had reached agreement on the terms of a recommended cash and share offer
for the entire issued and to be issued share capital of LASMO. I am writing to
explain the background to the transaction and the reasons why the LASMO board
recommends that LASMO Securityholders accept the Offer.

Further details of the Offer are set out in the letter from Goldman Sachs and in
Appendix I of this document.

2.  TERMS OF THE OFFER

At the time of the Announcement, the Offer valued each LASMO Share at 180 pence,
based on an exchange rate of US$1.4484: L1 and the NYSE Closing Price of
US$62 13/16 per Amerada Hess Share on 3 November 2000, the last NYSE trading day
prior to the announcement of the Offer. The cash element of the consideration
represents approximately 125 pence per LASMO Share.

The Offer now values each LASMO Share at    --   pence, based on an exchange
rate of US$   --   : L1.00 and the NYSE Closing Price of US$   --   per Amerada
Hess Share on  -- December 2000, the last NYSE trading day prior to the posting
of this document.

The Offer, which will be subject to the Conditions and further terms set out in
the letter from Goldman Sachs and Appendix I, will be made on the following
basis:

<TABLE>
<S>                                                         <C>
FOR EVERY 78.7 LASMO SHARES HELD                            L98.29 IN CASH AND 1 NEW AMERADA HESS SHARE
FOR EVERY 78.7 LASMO ADSS HELD                              L294.87 IN CASH AND 3 NEW AMERADA HESS
  (EACH ADS REPRESENTING 3 LASMO SHARES)                    SHARES
</TABLE>

There will be a Mix and Match Election under which LASMO Securityholders who
accept the Offer may elect to vary the proportions of Amerada Hess Shares and
cash (and/or Loan Notes, if applicable) which they receive, subject to other
LASMO Securityholders making opposite elections.

There will also be a Loan Note Alternative in respect of the cash element of the
Offer (other than for US persons and certain overseas shareholders).

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.

3.  BACKGROUND TO AND REASONS FOR RECOMMENDING ACCEPTANCE OF THE OFFER

The stock market performance of the UK independent exploration and production
sector has been disappointing for investors. Even the recent surge in oil prices
has not been reflected in a significant re-rating of share prices in the sector.
Between 1 January 1999 and 3 November 2000, the last London
                                        7
<PAGE>   10

Stock Exchange dealing day prior to the announcement of the Offer, LASMO's share
price only increased from 100 pence to 141 pence, despite the price of Brent
Crude moving from US$10.48 per barrel to US$31.73 over the same period and
despite your company's cashflow and profit gearing to higher oil prices.

This share price performance has been an area of concern for your board and we
therefore initiated an extensive analysis of a broad range of options earlier
this year. These options were against the background of the following matters:

     -  our share buyback announcement earlier this year was well received by
        shareholders;

     -  our talks on asset disposals with other industry players led us to the
        conclusion that, in the current business and oil price environment,
        LASMO faced highly favourable sale conditions for its portfolio; and

     -  continuing industry consolidation meant that scale was becoming
        increasingly important in the oil industry. The larger companies have
        lower cost bases, are able to deliver higher returns on a substantially
        lower and hence more competitive cost of capital and are able to take on
        greater investment risk within the scope of significantly larger
        portfolios. LASMO needed to respond to this trend or risk becoming less
        competitive in accessing projects and in delivering the required balance
        of risk and return to shareholders.

Your board was therefore unanimous in deciding to pursue Amerada Hess' proposal.
The Offer, which represented at the time of Announcement a premium of
approximately 28 per cent. to the Closing Price of a LASMO Share on 3 November
2000, the last London Stock Exchange dealing day prior to the Announcement, and
a premium of approximately 33 per cent. to the average Closing Price of a LASMO
Share over the 6 months prior to the Announcement, includes a significant
proportion of cash whilst also providing our shareholders with the opportunity
to participate in the enlarged group. Your board has carefully considered the
benefits of the transaction for holders of shares in the enlarged Amerada Hess
Group. The combination will result in a larger, more diversified asset base with
a growing production profile and strong reserve life. In addition, we believe
that combining LASMO's exploration skills with Amerada Hess' proven development
expertise will create a more competitive company able to deliver better returns.
Following extensive negotiations, your board was unanimous in deciding that the
Offer from Amerada Hess should be recommended to shareholders.

4.  LOW COST DEALING FACILITY

Amerada Hess is exploring the possibility of providing a low cost dealing
facility which, subject to compliance with all necessary legal and regulatory
constraints, may be put in place for shareholders for a limited period following
completion of the Offer. Under these arrangements, our shareholders would be
able to elect to sell the new Amerada Hess Shares which they receive under the
Offer up to a maximum transaction value.

5.  MANAGEMENT AND EMPLOYEES

Amerada Hess has indicated that it attaches great importance to the skills and
experience of the management and employees of LASMO. The enlarged group will
have a broader geographic spread than either Amerada Hess or LASMO has
independently. The boards of both companies therefore believe that the
combination of Amerada Hess and LASMO, with its strong prospects for continued
growth, will provide enhanced opportunities for the employees of both groups.

Amerada Hess has given assurances to the board of LASMO that, on the Offer
becoming or being declared unconditional in all respects, the accrued employment
rights of employees of LASMO, including pension rights, will be fully
safeguarded.

6.  ACTION TO BE TAKEN TO ACCEPT THE OFFER

The procedure for acceptance of the Offer is set out on pages 27 to 30 of this
document and in the accompanying Acceptance Form. In order to accept the Offer,
you should ensure that you return your completed Acceptance Form as soon as
possible and, in any event, so as to be received by no later than 3.00 pm
(London time), 10.00 am (New York City time) on    --   2000.

to the Announcement, and a premium of approximately 33 per cent. to the average
closing mid-market price of a LASMO Share over the 6 months prior to
Announcement.

 --   DOES THE LASMO BOARD OF DIRECTORS SUPPORT THE OFFER?

The board of directors of LASMO unanimously recommends that you accept the
Offer. The board of directors of LASMO, who have been so advised by Schroder
Salomon Smith Barney, their financial adviser, consider the terms of the Offer
to be fair and reasonable. In providing advice to the LASMO board of directors,
Schroder Salomon Smith Barney has taken into account the directors' commercial
assessments. Each member of the board of directors has agreed to accept the
Offer for all of his Shares and ADSs. See the Letter from the Chairman of LASMO
in this Offer Document.

 --   DO ANY OTHER SHAREHOLDERS SUPPORT THE OFFER?

We have received undertakings from two major shareholders, Schroder Investment
Management Limited and Electrafina S.A., to accept the Offer, except in certain

per cent of the existing LASMO ordinary share capital.

 --   IS YOUR FINANCIAL CONDITION RELEVANT TO MY DECISION TO ACCEPT THE OFFER?

Yes. If you accept the Offer, part of your consideration will be in the form of
Amerada Hess Shares, and you should consider our financial condition before you
decide to become one of our shareholders through the Offer.

We believe we are well positioned to provide long-term growth and to withstand
volatile energy price environments as a result of our strong cash flow, reduced
cost structure, strong production growth and strong balance sheet. At 30
September 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. After
consummation of this transaction, Amerada Hess' debt to capitalisation ratio is
expected to be 54 per cent., falling to 42 per cent. and 28 per cent. at year
end 2001 and 2002, respectively, based on anticipated cash flows.

We have investment grade ratings on our public debt. Following announcement of
this transaction, Standard & Poor's raised its rating from BBB to BBB+, and
Moody's Investors Service confirmed its rating of Baa1.

You should also review the information set forth in Appendix III and the

 --   HOW LONG DO I HAVE TO DECIDE WHETHER TO ACCEPT THE OFFER?

You will have until 3:00 pm, London time, 10:00 am, New York City time, on
   --   2000, to decide whether to accept the Offer, unless the Offer is
extended. However, if you cannot deliver everything that is required in order to
make a valid tender of LASMO ADSs by that time, you may be able to use a
guaranteed delivery procedure, which is described later in this Offer Document.
See paragraph 18 of the Letter from Goldman Sachs and paragraphs 10, 11 and 12
of Part B of Appendix I of this Offer Document.

 --   WHAT IS THE DIFFERENCE BETWEEN THE INITIAL OFFER PERIOD AND THE SUBSEQUENT
OFFER PERIOD?

Usually, in the UK, a takeover offer must be held open for 21 calendar days but
can become wholly unconditional at any time, including before the date on which
it is to close, if its conditions are then fulfilled, satisfied or (if capable
of waiver) waived. Because the Offer is required to comply with US securities
laws, the Offer must remain open for a minimum of 20 business days and cannot
become unconditional until the end of that period. Accordingly, the Offer will
remain open until 3.00 pm (London time), 10.00 am (New York City time) on
   --   , 2000 and will then lapse if the Offer has not then become
unconditional in all respects unless Amerada Hess, in its sole discretion,
decides to extend the Offer.

The Initial Offer Period is the period between the date of this document and
3.00 pm (London time), 10.00 am (New York City time), on    --   , 2000, or any
later time and date to which the time for satisfaction, fulfilment, or, if
capable of waiver, waiver of the Conditions is extended. The Initial Offer
Period is the time during which withdrawal rights apply. The Subsequent Offer
Period starts as soon as the Initial Offer Period terminates if the Offer has
then become unconditional in all respects. During the Subsequent Offer Period no
withdrawal rights apply, except in limited circumstances. See paragraph 4 of
Part B of Appendix I of this document.

 --   CAN THE OFFER BE EXTENDED AND UNDER WHAT CIRCUMSTANCES?

Yes. If all of the Conditions to the Offer have not been either satisfied,
fulfilled or, to the extent permitted, waived by Amerada Hess by 3:00 pm, London
time, 10:00 am, New York City time, on    --   2000, Amerada Hess may choose,
but shall not be obliged to, extend the Initial Offer Period. Once all the
Conditions have been either satisfied, fulfilled or, to the extent permitted,
waived by Amerada Hess, we will extend the Offer for a Subsequent Offer Period
of at least 14 calendar days. See paragraph 1 of Part B of Appendix I of this
Offer Document.

 --   HOW WILL I BE NOTIFIED IF THE OFFER IS EXTENDED?

If we extend the Offer, we will make a public announcement of the extension, not
later than 8:00 am London time and 8:00 am New York City time, on the next
business day after the day on which the Offer was scheduled to expire. See
paragraph 3 of Part B of Appendix I.

 --   WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE OFFER?

     -  We are not obliged to purchase any LASMO Shares and/or LASMO ADSs unless
        we have received valid acceptances (which have not been properly
        withdrawn) in respect of at least 90 per cent. of the LASMO Shares
        (including LASMO Shares represented by LASMO ADSs) to which the Offer
        relates. We may reduce this percentage, subject to certain limits. At
        least five business days prior to any reduction, we will announce that
        we may do this through a press release and newspaper advertisement of
        general circulation in the United States.

     -  We are not obliged to purchase any LASMO Shares and/or LASMO ADSs unless
        the new Amerada Hess Shares to be issued under the Offer have been
        authorized for listing on the NYSE and the registration statement filed
        by us with the SEC has been declared effective.

     -  We are not obliged to purchase any LASMO Shares and/or LASMO ADSs if,
        among other things, the Offer has been referred to the United Kingdom
        Competition Commission by the Secretary of State for Trade and Industry
        or the applicable waiting period under the United States
        Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, has
        not expired or been waived.

See paragraph 7 of the Letter from Goldman Sachs, Part A of Appendix I and Part
B of Appendix I of this Offer Document.

 --   HOW DO I ACCEPT THE OFFER?

To accept the Offer, you must deliver the certificates representing your LASMO
Shares or your LASMO ADRs, together with a completed Form of Acceptance in the
case of LASMO Shares or a completed Letter of Transmittal in the case of ADSs,
to the UK Receiving Agent or the US Depositary, respectively, not later than the
time the Offer expires. If your Shares or ADSs are held in "street name" in the
United States, they can be tendered by your nominee through the applicable book
entry transfer system. In the case of ADSs, if you cannot get any document or
instrument that is required to be delivered by the expiration of the Offer, you
may gain some time by following the procedures for guaranteed delivery. See
paragraph 18 of the Letter from Goldman Sachs and paragraphs 10, 11 and 12 of
Part B of Appendix I of this Offer Document.

 --   UNTIL WHAT TIME CAN I WITHDRAW MY ACCEPTANCE?

You can withdraw your acceptance at any time until the Initial Offer Period has
expired. We intend to have a Subsequent Offer Period during which there will be
no withdrawal rights, except in limited circumstances. See paragraph 19 of the
Letter from Goldman Sachs and paragraph 4 of Part B of Appendix I of this Offer
Document.

 --   HOW DO I WITHDRAW MY ACCEPTANCE?

To withdraw Shares or ADSs, you must deliver a written notice of withdrawal with
the required information to the UK Receiving Agent or the US Depositary,
respectively, while you still have the right to withdraw the Shares or ADSs. See
paragraph 4 of Part B of Appendix I of this Offer Document.

 --   WILL THE OFFER BE FOLLOWED BY A COMPULSORY ACQUISITION?

Yes. If all of the Conditions to the Offer are either satisfied, fulfilled or,
where permitted, waived and we have acquired 90 per cent. in nominal value of
LASMO Shares (including LASMO Shares represented by LASMO ADSs) then we will be
entitled to and intend to acquire all remaining LASMO Shares and LASMO ADSs
pursuant to the Companies Act. Holders of LASMO Shares and LASMO ADSs subject to
the compulsory acquisition would receive the same consideration as those holders
of LASMO Shares and LASMO ADSs who accept the Offer. See paragraph 24 of the
Letter from Goldman Sachs and paragraph 11 of Appendix VI of this Offer
Document.

 --   IF I DECIDE NOT TO ACCEPT, HOW WILL THE OFFER AFFECT MY SECURITIES?

If we are able to, we will acquire all LASMO Shares and LASMO ADSs for which we
have not received acceptances pursuant to the compulsory acquisition provisions
of the Companies Act. We also intend to apply, or request that LASMO apply, to
the NYSE, the London Stock Exchange and the UK Listing Authority to have the
LASMO ADSs and LASMO Shares de-listed, terminate the deposit agreement through
which the ADS programme is operated and seek to have the registration of the
LASMO ADSs and LASMO Shares under the Exchange Act terminated. Termination of
registration under the Exchange Act would substantially reduce the information
required to be furnished to holders of the LASMO ADSs and LASMO Shares and would
make certain other provisions of the Exchange Act inapplicable to LASMO. See
paragraph 24 of the Letter from Goldman Sachs and paragraph 13 of Appendix VI of
this Offer Document.

 --   WHAT IS THE MARKET VALUE OF MY LASMO SECURITIES AS OF A RECENT DATE?

On 3 November 2000, the last dealing day before we announced the Offer, the
Closing Price of LASMO Shares reported on the London Stock Exchange was 141
pence per share and the last sale price of ADSs reported on the NYSE was
US$6 1/4. Between 3 November 1999 and 3 November 2000, the price of LASMO Shares
ranged between 89.5 pence and 155.5 pence per share and the price of LASMO ADSs
ranged from US$4 7/16 and US$7 1/4 per ADS. We advise you to obtain a recent
quotation for LASMO Shares and LASMO ADSs in deciding whether to accept the
Offer. See paragraph 16 of the Goldman Sachs Letter and paragraph 3 of Appendix
VI of this Offer Document.

 --   WILL I HAVE TO PAY ANY FEES OR COMMISSIONS?

If you are the record owner of your LASMO Shares and/or LASMO ADSs and you
accept the Offer, you will not have to pay brokerage fees or similar expenses.
If you own your LASMO Shares and/or LASMO ADSs through a broker or other
nominee, and your broker accepts the Offer on your behalf, your broker or
nominee may charge you a fee for doing so. You should consult your broker or
nominee to determine whether any charges will apply. See paragraphs 2 and 5 of
the Letter from Goldman Sachs and Appendix II of this Offer Document.

 --   WILL I BE TAXED ON THE AMERADA HESS SHARES AND CASH THAT I RECEIVE?

A UK resident holder will generally realise an immediate chargeable gain or
allowable loss to the extent that he receives cash under the Offer. To the
extent that such a holder receives Amerada Hess Shares and/or Loan Notes, a
further amount of chargeable gain or allowable loss on the holder's LASMO Shares
will generally be rolled over into those Amerada Hess Shares and/or, in the case
of Loan Notes, rolled over (for a non-corporate holder) or held over (for a
corporate holder) for UK capital gains tax purposes.

A US holder generally will recognize gain or loss upon the receipt of Amerada
Hess Shares and cash in exchange for such holder's LASMO Shares or LASMO ADSs
pursuant to the Offer in an amount equal to the difference between (a) the sum
of (i) the fair market value of such Amerada Hess Shares received and (ii) the
US Dollar value of the pounds sterling that would have been received on the date
of receipt and (b) the US holder's adjusted tax basis in the LASMO Shares or
LASMO ADSs, as the case may be.

Further information regarding the application of both US and UK tax laws to
LASMO Securityholders who accept the Offer is set out in paragraphs 14 and 15 of
Appendix VI of this Offer Document.

 --   IF I CHOOSE TO ACCEPT THE OFFER, HOW WILL MY RIGHTS AS AN AMERADA HESS
      SHAREHOLDER DIFFER FROM MY RIGHTS AS A LASMO SECURITYHOLDER?

An explanation of the material differences between the rights of LASMO
Securityholders and Amerada Hess shareholders is contained in Appendix VII of
this document.

 --   HOW WILL THIS TRANSACTION BE TREATED FOR ACCOUNTING PURPOSES?

The transaction will be accounted for using the purchase method of accounting.
See paragraph 17 of the letter from Goldman Sachs.

 --   WHERE CAN I FIND MORE INFORMATION ABOUT AMERADA HESS AND LASMO?

You can find more information about Amerada Hess and LASMO from various sources
described in the sections entitled "Where You Can Find Additional Information
about Amerada Hess" in Appendix III to this document and "Where You Can Find
Additional Information about LASMO" in Appendix IV to this document.

 --   WHO CAN ANSWER QUESTIONS I MIGHT HAVE ABOUT THE OFFER?

If you have any questions about procedures for acceptance of the Offer, you
should contact, in the UK, the UK Receiving Agent, Computershare Services PLC,
on 0870 702 0100 or, in the US, the Information Agent, D.F. King & Co., Inc. on
1 (800) 628 8536 (Toll-Free).

To all holders of LASMO Securities and, for information only, to participants in
the LASMO Share Option Schemes, the LASMO Profit Sharing Scheme and the Monument
1996 Participating Share Plan

Dear Sir or Madam,

                            AMERADA HESS CORPORATION
                      RECOMMENDED CASH AND SHARE OFFER FOR
                                   LASMO PLC

1.  INTRODUCTION

On 6 November 2000, the boards of Amerada Hess and LASMO announced that they had
reached agreement with respect to the terms of a recommended cash and share
offer for the entire issued and to be issued share capital of LASMO. This letter
contains the formal Offer to be made by Goldman Sachs on behalf of Amerada Hess
(except in the United States, where Amerada Hess is making the Offer on its own
behalf) and should be read in conjunction with the accompanying Acceptance Form.
Your attention is drawn to the letter from the Chairman of LASMO on pages 7 to 9
of this document which states that 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 Securityholders to accept the Offer, as they have agreed to do
themselves in respect of their aggregate holdings of 324,311 LASMO Shares.

TO ACCEPT THE OFFER, THE RELEVANT ACCEPTANCE FORM, TOGETHER WITH ALL OTHER
REQUIRED DOCUMENTS, MUST BE COMPLETED AND RETURNED AS SOON AS POSSIBLE BUT, IN
ANY EVENT, SO AS TO BE RECEIVED BY NO LATER THAN 3.00 PM (LONDON TIME), 10.00 AM
(NEW YORK CITY TIME), ON    --   2000. The procedure for acceptance of the Offer
is set out on pages 27 to 30 of this document and in the accompanying Acceptance
Form.

2.  THE OFFER

Amerada Hess and Goldman Sachs on behalf of Amerada Hess (outside the United
States) hereby offer to acquire, subject to the Conditions and the further terms
set out or referred to in this document and in the relevant Acceptance Form, all
of the LASMO Securities on the following basis:

<TABLE>
<S>                                           <C>
FOR EVERY 78.7 LASMO SHARES HELD              L98.29 IN CASH AND 1 NEW AMERADA HESS SHARE
FOR EVERY 78.7 LASMO ADSS HELD                L294.87 IN CASH AND 3 NEW AMERADA HESS SHARES
  (EACH ADS REPRESENTING 3 LASMO SHARES)
</TABLE>

At the time of the Announcement, the Offer valued 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 L2.4 billion
based in each case on the Closing Price per Amerada Hess Share of US$62 13/16 on
3 November 2000 (the last NYSE trading day prior to the Announcement) and an
exchange rate of US$1.4484: L1.00. The cash element of the consideration
represents approximately 125 pence per LASMO Share.

The Offer now values each LASMO Share at    --   pence, based on an exchange
rate of US$   --   : L1.00 and the NYSE Closing Price of US$   --   per Amerada
Hess Share on  -- December 2000, the last NYSE trading day prior to the posting
of this document.

                                       18
<PAGE>   21

The Offer (valued at 180 pence per LASMO Share at the time of the Announcement)
represented a premium of approximately 28 per cent. to the Closing Price of a
LASMO Share at the close of business on 3 November 2000, the last London Stock
Exchange dealing day prior to the Announcement, and a premium of approximately
33 per cent. to the average Closing Price of a LASMO Share over the 6 months
prior to the 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 Offer extends to all LASMO Shares (including LASMO Shares represented by
LASMO ADSs) unconditionally allotted or issued on the date of the Offer Document
and any further such shares which are unconditionally allotted or issued while
the Offer remains open for acceptance or on or before such earlier time and/or
date as Amerada Hess may (subject to the City Code, US securities laws and/or
with the consent of the Panel) decide.

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, 1,344,328,323 LASMO Shares had been issued (including LASMO
Shares represented by LASMO ADSs) and 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 to adjust the Offer consideration, by reducing rateably the aggregate
number of Amerada Hess Shares to be issued under the Offer, if any issue of
LASMO Shares in excess of these amounts would mean that Amerada Hess would
otherwise be obliged to issue more than 17.18 million new Amerada Hess Shares
under the Offer or pursuant to the statutory compulsory acquisition arrangements
under Section 429 of the Companies Act. In that event, LASMO Securityholders
will instead be entitled to receive cash at a rate of L43.37 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
trading day prior to the Announcement, translated into sterling at the rate of
US$1.4484: L1.00.

All LASMO Securities 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 6 November
2000.

In so far as a dividend or other distribution was proposed, declared, made or
payable in respect of a LASMO Security 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 Security will be reduced by the
amount of the dividend and/or distribution except in so far as the LASMO
Security 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 Securityholder in respect of a LASMO Security
will be reduced by the amount of any such reduction of the consideration payable
in respect of that LASMO Security 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.

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 its portfolio than
it has in the past.

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 substantially all
of LASMO's anticipated 2001 oil production to support the accretive nature of
the transaction to earnings and cash flow and permit significant debt

                                       19
<PAGE>   22

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:

     -  continue the transformation of Amerada Hess into 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);

     -  achieve Amerada Hess' strategic objective to increase its international
        reserves outside the US and North Sea; international proved reserves
        will be increased to 42 per cent. on a pro-forma basis from 14 per cent.
        of total proved reserves at year-end 1999;

     -  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 proved reserve life from 8.2 to 9.8
        years;

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

     -  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;

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

     -  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;

     -  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);

     -  increase Amerada Hess' production from an estimated 374,000 boe per day
        in 2000 to an expected 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.  MIX AND MATCH ELECTION

LASMO Securityholders who validly accept the Offer may elect under the Mix and
Match Election to vary the proportions in which they receive Amerada Hess Shares
and cash and/or Loan Notes, if applicable, in respect of their LASMO Securities.
Insofar as a LASMO Securityholder is entitled to receive additional cash under
the Mix and Match Election, it will be payable in an amount per Amerada Hess
Share equal to the sterling equivalent of the Closing Price, at the relevant
time, of each such Amerada Hess Share to which the shareholder would have been
entitled under the basic terms of the Offer if the shareholder had not elected
to receive additional cash. The relevant time for ascertaining the value of an
Amerada Hess Share for these purposes will be the close of trading on the NYSE
on the most recent NYSE trading day before the LASMO Securityholder's
entitlement under the Mix and Match Election falls to be determined. The
sterling equivalent will be determined at the US dollar to pound sterling
exchange rate at that time, as determined by Goldman Sachs.

Although the Offer will remain open for a Subsequent Offer Period of at least 14
calendar days after the Closing Date on which the Offer becomes or is declared
unconditional in all respects (at the end of the Initial Offer Period), the Mix
and Match Election will remain open until but not beyond 3.00 pm (London time),
10.00 am (New York City time) on the date falling five calendar days after the
Offer becomes or is declared unconditional in all respects. Mix and Match
Elections must be made at the same time as the acceptances of the Offer to which
they relate, on the relevant Acceptance Form.

The maximum number of new Amerada Hess 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 a LASMO
Securityholder to make a Mix and Match Election will depend on the extent to
which other LASMO Securityholders make opposite elections. To the extent that
elections

                                       20
<PAGE>   23

cannot be satisfied in full, they will be scaled down on a pro rata basis. To
the extent that elections can be satisfied, LASMO Securityholders will receive
new Amerada Hess Shares instead of cash (and/or Loan Notes, if applicable), and
vice versa.

Accordingly, LASMO Securityholders who make Mix and Match Elections will not
know the exact number of new Amerada Hess Shares or the amount of cash (and/or
Loan Notes) they will receive until settlement of the consideration under the
Offer, although an announcement of the approximate extent to which Mix and Match
Elections will be satisfied will be made two days after the Mix and Match
Election ceases to be open for acceptance.

In addition, Amerada Hess reserves the right to limit the extent to which
elections under the Mix and Match Election (or any subsequent mix and match
election) will be capable of being satisfied by cash and/or Amerada Hess Shares
released by opposite elections by other LASMO Securityholders insofar as it
determines this to be necessary or desirable with a view to ensuring that the
aggregate number of Amerada Hess Shares and the aggregate amount of cash payable
to all LASMO Securityholders do not exceed the levels which would apply in the
event of full acceptance of the Offer with a single Closing Date for the Mix and
Match Election, whether as a result of the operation of the provisions of
Sections 429 to 430F of the Companies Act (which permit compulsory acquisition
of outstanding shares following a takeover offer) or otherwise.

The Mix and Match Election is conditional upon the Offer becoming or being
declared unconditional in all respects. Your attention is drawn to paragraph 18
of this letter and to paragraph 5 of part B of Appendix 1 of this document which
set out the procedure for making a Mix and Match Election.

5.  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 for US
persons and certain overseas shareholders not resident in the United Kingdom)
will be able to elect to receive Loan Notes to be issued by Amerada Hess on the
following basis:

FOR EVERY L1 OF CASH CONSIDERATION UNDER THE OFFER      L1 NOMINAL 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 L1 nominal value. All fractional entitlements will be
disregarded and not paid.

Goldman Sachs has advised that, based on market conditions on  -- December 2000
(the latest practicable day prior to the posting of this document), the value of
the Loan Notes (had they been in issue on that day) would have been not less
than    --   pence per L1 in nominal value.

The Loan Notes will be transferable (subject to certain conditions) in multiples
of L500 or such lower number 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 2 July 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 2 July 2001 in respect of the period up to (but
excluding) 2 July 2001.

The Loan Notes will be redeemable at par at the option of the holders, in whole
or in any part (being L500 in nominal amount or any integral multiple thereof),
on 31 December 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

                                       21
<PAGE>   24

31 December 2001 to redeem 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 L2 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 (including the Mix and Match Election).

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 are set forth in Appendix II.

6.  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 324,311 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.

The Announcement stated that Amerada Hess had 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. Schroder Investment Management Limited, being a fund manager, has given
an undertaking to accept the Offer in respect of 177,943,047 LASMO Shares
insofar as the relevant clients have not withdrawn or altered their mandate (in
a manner inconsistent with acceptance) at the time required for acceptance.
Schroder Investment Management Limited has notified Amerada Hess that its
undertaking applies to 171,616,233 LASMO Shares and not 177,943,047 LASMO Shares
as stated in the Announcement. Therefore, the irrevocable undertakings received
from the above institutions in fact represent an aggregate of 269,952,394 LASMO
Shares, representing approximately 20.08 per cent. of LASMO's issued share
capital.

The undertakings from Schroder Investment Management Limited and Electrafina
S.A. 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 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 trading day
immediately preceding announcement of the new offer.

Accordingly, Amerada Hess has received irrevocable undertakings in respect of a
total of 270,276,705 LASMO Shares representing approximately 20.1 per cent. of
the existing issued LASMO ordinary share capital.

7.  CONDITIONS AND FURTHER TERMS OF THE OFFER

The Offer (including the Loan Note Alternative) is subject to the Conditions and
further terms set out in Appendix I.

8.  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, Gabon,
Indonesia, Thailand, Azerbaijan, Algeria and Brazil.

Amerada Hess produces approximately 370,000 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.

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 the United States
and the North Sea and increase reserves outside these areas to at
                                       22
<PAGE>   25

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 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 30 September 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. After consummation of this transaction, Amerada Hess'
debt to capitalisation ratio is expected to be 54 per cent., falling to 42 per
cent. and 28 per cent. at year end 2001 and 2002 respectively, based on
anticipated cash flows.

Refining and marketing has become a smaller, but more profitable, portion of
Amerada Hess' portfolio than it was in the past.

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 crude oil distillation 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 915 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 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 US$8.5 billion (1999: US$5.2 billion) and net income of US$683
million (1999: US$307 million). Net assets as at 30 September 2000 were US$3.5
billion (31 December 1999: US$3.0 billion). For the full year ended 31 December
1999, Amerada Hess had total revenues of US$7.5 billion (1998: US$6.6 billion)
and net income of US$438 million (1998: US$(459) million).

Further information with respect to Amerada Hess is set forth in Appendix III to
this document.

9.  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 31 December 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. located in Indonesia, 29 per cent. located in
Venezuela, 14 per cent. located in North Africa and 6 per cent. located in
Pakistan. For the year ended 31 December 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 L463 million
(1999: L216 million) and profit before exceptional items and taxation of L187
million (1999: L35 million). Net assets as at 30 June, 2000 were L1,467 million.
For the full year ended 31 December 1999, LASMO had sales of L594 million (1998:
L484 million) and profit before exceptional items and taxation of L170 million
(1998: L1 million).

Further information with respect to LASMO is set forth in Appendix IV to this
document.

10. FINANCING OF THE OFFER

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

Further details regarding these bank facilities are set out in paragraph 7 of
Appendix VI.

11. MANAGEMENT AND EMPLOYEES

The 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 the Amerada Hess Group.

12. LASMO SHARE OPTION SCHEMES

The Offer will extend to any further LASMO Shares (including LASMO Shares
represented by LASMO ADSs) unconditionally allotted or issued at the date of
this document and any further such shares which are unconditionally allotted or
issued while the Offer remains open for acceptance (or on or before such earlier
time and/or date as Amerada Hess may, subject to the City Code, US securities
laws 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.

13. FRACTIONS

Fractions of new Amerada Hess Shares will not be allocated or issued to
accepting LASMO Securityholders. Fractional entitlements to 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 Securities entitled to them. Any
LASMO Securityholder may elect (by separate written notice to the UK Receiving
Agent or the US Depositary accompanying his or her Acceptance Form) to receive
the payment due in respect of fractional entitlements in either pounds sterling
or US dollars. In the absence of any such election, such payment will be made to
holders of LASMO ADSs in US dollars and to LASMO Shareholders in pounds
sterling, the proceeds having been converted from US dollars at a prevailing
exchange rate selected by Amerada Hess at the relevant time. Amerada Hess will
not be liable to LASMO Securityholders or any other person in respect of the
timing of any such sale or the price or exchange rate achieved in respect of any
such sale or conversion. Individual entitlements to amounts of less than L5.00
(or its equivalent in US dollars at the relevant time) will not be paid to
holders of LASMO Securities but will be retained for the benefit of the enlarged
Amerada Hess Group.

14. NEW AMERADA HESS SHARES

The new Amerada Hess Shares will rank pari passu in all respects with existing
Amerada Hess Shares, including the right to any dividends and other
distributions declared, paid or made by reference to a record date after the
date on which they are issued. For the avoidance of doubt, LASMO Securityholders
will not be entitled to 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 will be delivered in accordance with the terms of
the Offer and will be 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.

Amerada Hess Shares are traded in US dollars on the NYSE and dividends are
declared and paid in US dollars. The sterling value of any investment in Amerada
Hess Shares and any dividend income from that investment (payable in US dollars
and subject to US withholding tax) will be affected by fluctuations in the
dollar to sterling exchange rate from time to time.

The new Amerada Hess Shares are expected to be authorised for listing, subject
to official notice of issuance, on the NYSE, but they will not be listed or
traded on the London Stock Exchange or any other stock exchange.

                                       24
<PAGE>   27

Amerada Hess is exploring the possibility of providing a low cost dealing
facility which, subject to compliance with all necessary legal and regulatory
constraints, may be put in place for LASMO Securityholders for a limited period
following completion of the Offer. Under these arrangements, LASMO
Securityholders would be able to elect to sell the new Amerada Hess Shares which
they receive under the Offer up to a maximum transaction value.

15. ILLUSTRATIVE COMPARATIVE PER SHARE DATA

The following table presents historical net income, cash dividends and book

NOTES

(i)  Based on the cash element of the consideration of L98.29 for every 78.7
     LASMO Shares.

(ii) Based on the Closing Price of an Amerada Hess Share on  -- December 2000
     (the last practicable business day prior to the posting of this document)
     of $  -- and an exchange rate of $  -- : L1.00, being the noon-buying rate
     published by the Federal Reserve Bank of New York on that date.

(iii) Based on the Closing Price of a LASMO Share on 3 November 2000 (the last
      practicable business day prior to the announcement of the Offer).

(iv) The gross income from the cash consideration is based on an assumption that
     the cash consideration is re-invested so as to yield  -- per cent. gross
     per annum, being the gross yield shown by the FT Actuaries Average Gross
     Redemption Yield for medium coupon U.K. government securities of up to five
     years maturity on    --   , as published in the Financial Times on  --
     December 2000 (the last practicable business day prior to the posting of
     this document).

(v) The gross dividend income from a new Amerada Hess Share is based on the
    aggregate of the quarterly dividends of $0.15, $0.15, $0.15 and $0.15 per
    Amerada Hess Share for the periods ending 30 September 2000, 30 June 2000,
    31 March 2000 and 31 December 1999, respectively. The gross dividend income
    is based on an exchange rate of US$   --   : L1.00, being the average noon
    buying rate published by The Federal Reserve Bank of New York for the period
    1 October 1999 to 30 September 2000.

(vi) The gross dividend income from a LASMO Share is based on the final dividend
     for the year ended 31 December 1999 of 2.5p per LASMO Share grossed up by
     the amount of the related UK tax credit.

(vii) Except as expressly stated in (v) and (vi) above, no account has been
      taken of any potential liability to taxation. The comparison would be very
      difficult for some categories of shareholder if tax were taken into
      account, because of different tax rates applying to different categories
      of income.

17. ACCOUNTING TREATMENT

Amerada Hess expects that the transaction will be accounted for using the
purchase method of accounting for business combinations. Under the purchase
method, the consummation of the Offer will be treated as an acquisition of LASMO
by Amerada Hess, and Amerada Hess will allocate the total purchase price among
the acquired assets and liabilities based on their estimated fair values at
closing of the transaction.

RELEVANT ACCEPTANCE FORM.

(a) Holders of LASMO Shares

     The attention of LASMO Shareholders is drawn to paragraphs 10 and 11 of
     Part B of Appendix I to this document and to the relevant provisions of the

     certificated and uncertificated (that is, in CREST) form, you should
     complete a separate Form of Acceptance for each holding. In addition, you
     should complete a separate Form of Acceptance for LASMO Shares held in
     uncertificated form, but under different member account IDs. Similarly, you
     should complete a separate Form of Acceptance for LASMO Shares held in
     certificated form but under different designations. If you hold LASMO
     Shares in CREST you should also refer to paragraphs (vi) and (viii) below.
     ADDITIONAL FORMS OF ACCEPTANCE ARE AVAILABLE FROM THE UK RECEIVING AGENT
     AND THE INFORMATION AGENT.

     (i)    To accept the Offer

        To accept the Offer, you should complete Box 1 of the Form of
        Acceptance, check the details contained in Box 2 of the Form of
        Acceptance and, if your LASMO Shares are in CREST, complete Box 7 of the

        Form of Acceptance in accordance with the instructions printed on it.
        ALL HOLDERS OF LASMO SHARES WHO ARE INDIVIDUALS SHOULD SIGN BOX 6 OF THE

     (ii)   To elect for the Mix and Match Election

        To make a Mix and Match Election in respect of some or all of your LASMO
        Shares you should complete Box 3A (to elect for additional Amerada Hess
        Shares) OR Box 3B (to elect for additional cash) in addition to
        completing Box 1 and checking Box 2. You should then sign and date Box 6
        in accordance with the instructions printed on it. IN ALL CASES, HOLDERS
        OF LASMO SHARES WHO ARE INDIVIDUALS MUST SIGN BOX 6 OF THE FORM OF
        ACCEPTANCE IN THE PRESENCE OF A WITNESS, WHO SHOULD ALSO SIGN BOX 6 IN
        ACCORDANCE WITH THE INSTRUCTIONS PRINTED THEREON.

        You must not fill in both Box 3A and Box 3B. If you do so, you will be
        deemed not to have made a Mix and Match Election.

        Although the Offer will remain open for a Subsequent Offer Period of at
        least 14 calendar days after the Closing Date on which the Offer becomes
        or is declared unconditional in all respects (at the end of the Initial
        Offer Period), an election for the Mix and Match Election will not be
        valid unless by not later than 3.00 p.m. (London time), 10.00 a.m. (New
        York City time) on the date falling five calendar days after that
        Closing Date (i) the UK Receiving Agent has received the relevant Form
        of Acceptance, correctly completed in all respects and (ii) either (1)
        if the LASMO Shares concerned are in certificated form, the UK Receiving
        Agent has received all relevant share certificate(s) and/or other

        Part B of Appendix 1. Any Mix and Match Election must be made at the
        same time as the acceptance of the Offer to which it relates. The
        invalidity of an election for the Mix and Match Election (including the
        making of such election after the Mix and Match Election has closed)
        will not affect the validity of an acceptance of the Offer.

        LASMO Shares for which you are accepting the Offer, you should complete

        would otherwise be entitled under the Offer in respect of those LASMO
        Shares. Note that if you wish to receive all your cash entitlement under
        the Offer in Loan Notes, you should insert the same number of LASMO
        Shares in Box 4 as you have in Box 1.

        The attention of those holders of LASMO Shares considering accepting the
        Loan Note Alternative is drawn to paragraph 5 of this letter, to
        paragraph 6 of Part B of Appendix I to this document and to Appendix II
        of this document. IN ALL CASES HOLDERS OF LASMO SHARES WHO ARE
        INDIVIDUALS MUST SIGN BOX 6 OF THE FORM OF ACCEPTANCE IN THE PRESENCE OF
        A WITNESS, WHO SHOULD ALSO SIGN BOX 6 IN ACCORDANCE WITH THE
        INSTRUCTIONS PRINTED THEREON.

     (iv)  To elect for both the Mix and Match Election and the Loan Note
Alternative

        To elect for both the Mix and Match Election and the Loan Note
        Alternative, in respect of all of your LASMO Shares, you must complete
        Box 1 and in respect of such number of LASMO Shares in respect of which
        you wish to accept the Mix and Match Election and the Loan Note
        Alternative, either Box 3A or Box 3B, and Box 4, and, if appropriate,
        Boxes 5, 6, 7, 8 and/or Box 9, and then sign Box 6 in accordance with
        its instructions. Holders of LASMO Shares who are individuals must sign
        Box 6 of the Form of Acceptance in the presence of a witness, who should
        also sign Box 6 in accordance with the instructions printed on it.

        If you make a Mix and Match Election at a time when it is open and elect
        for the Loan Note Alternative, the following will apply:

        (1)   the Mix and Match Election will take effect first and will,
             subject to elections of other Securityholders, adjust the amount of
             cash to which you become entitled under the Offer;

        (2)   a "loan note ratio" will be calculated by dividing the number of
             LASMO Shares entered in Box 4 by the total number of LASMO Shares
             entered in Box 1; and

        (3)   the total amount of Loan Notes you will receive will be calculated
             by multiplying your total cash entitlement under the Offer,
             following implementation of your Mix and Match Election, by your
             loan note ratio.

        LASMO Securityholders should note that, for acceptances after the date
        falling five calendar days after the Closing Date on which the Offer
        becomes unconditional in all respects (at the end of the Initial Offer
        Period), the Mix and Match Election will not be available and
        accordingly any Mix and Match Election for additional cash consideration
        made after that date shall be invalid and the Loan Note Alternative will
        not apply in respect thereof.

     (v)   Return of the Form of Acceptance

        To accept the Offer, the Form of Acceptance must be completed and
        returned, whether or not your LASMO Shares are in CREST. The completed,
        signed and (if you are an individual) witnessed Form of Acceptance,
        together with, if your LASMO Shares are not in CREST, the share
        certificate(s) and/or other document(s) of title for your LASMO Shares,
        should be returned (IF YOU ARE NOT IN THE UNITED STATES) BY POST OR BY

        RECEIVED BY NO LATER THAN 3.00 PM (LONDON TIME), 10.00 AM (NEW YORK CITY
        TIME), ON    --   2000. A reply-paid envelope is enclosed for your
        convenience and may be used by holders of LASMO Shares for returning
        Forms of Acceptance within the United Kingdom or the United States (as
        the case may be). The instructions printed on the Form of Acceptance
        shall be deemed to form part of the terms of the Offer.

                                       28
<PAGE>   31

        Any Form of Acceptance received in an envelope postmarked in Canada,
        Australia or Japan or otherwise appearing to Amerada Hess or its agents
        to have been sent from Canada, Australia or Japan may be rejected as an
        invalid acceptance of the Offer. For further information for overseas
        LASMO Shareholders, see paragraph 23 of this letter and paragraph 9 of
        Part B of Appendix I to this document.

     (vi)  LASMO Shares in uncertificated form (that is, in CREST)

        If your LASMO Shares are in uncertificated form (that is, if you do not
        have a share certificate because your LASMO Shares are held in CREST),
        you should read carefully paragraph 10 of Part B of Appendix I to this
        document, which sets out the acceptance procedures for holders of LASMO
        Shares in uncertificated form.

        IF YOU ARE A CREST SPONSORED MEMBER, YOU SHOULD REFER TO YOUR CREST
        SPONSOR BEFORE TAKING ANY ACTION.

     (vii)  Share certificates not readily available or lost

        If your LASMO Shares are in certificated form, but your share
        certificates(s) and/or other document(s) of title is/are not readily
        available or is/are lost, the Form of Acceptance should nevertheless be
        completed, signed and returned as stated in paragraph (v) above together
        with any share certificate(s) and/or other document(s) of title that you
        have available, accompanied by a letter stating that the balance will
        follow or that you have lost one or more of your share certificate(s)
        and/or other document(s) of title to be forwarded as soon as possible.
        No acknowledgement of receipt of documents will be given. In the case of
        loss of your share certificate(s) and/or other document(s) of title, you
        should write as soon as possible to LASMO's registrars, Computershare
        Services PLC of PO Box 435, Owen House, 8 Bankhead Crossway North,
        Edinburgh, EH11 4BR, for a letter of indemnity for lost share
        certificate(s) and/or other document(s) of title which, when completed
        in accordance with the instructions given, should be returned to the UK
        Receiving Agent (if you are not in the United States) or to the US
        Depositary (if you are in the United States) at the relevant address set
        out in paragraph (v) above.

     (viii) Deposits of LASMO Shares into, and withdrawals of LASMO Shares from,
CREST

        Normal CREST procedures (including timings) apply in relation to any
        LASMO Shares that are, or are to be, converted from uncertificated to
        certificated form, or from certificated to uncertificated form, during
        the course of the Offer (whether any such conversion arises as a result
        of a transfer of LASMO Shares or otherwise). Holders of LASMO Shares who
        are proposing so to convert any such LASMO Shares are recommended to
        ensure that the conversion procedures are implemented in sufficient time
        to enable the person holding or acquiring the LASMO Shares as a result
        of the conversion to take all necessary steps in connection with an
        acceptance of the Offer (in particular, as regards delivery of share
        certificate(s) and/or other document(s) of title or transfers to an
        escrow balance as referred to in the acceptance procedures referred to
        in sub-paragraph (vi) above) PRIOR TO 3.00 PM (LONDON TIME), 10.00 AM
        (NEW YORK CITY TIME) ON    --   2000.

(b) Holders of LASMO ADSs

     The attention of holders of LASMO ADSs is drawn to paragraph 12 of Part B
     of Appendix I to this document and to the relevant provisions of the Letter
     of Transmittal.

     For a holder of LASMO ADSs evidenced by LASMO ADRs validly to accept the
     Offer, either (i) a properly completed and duly executed Letter of
     Transmittal, together with any required signature guarantees or, in the
     case of a book-entry transfer, an Agent's Message, and any other documents
     required by the Letter of Transmittal, must be received by the US
     Depositary at one of its addresses set out at the back of this document and
     either the LASMO ADRs evidencing such LASMO ADSs must be received by the US
     Depositary at one of such addresses or such LASMO ADRs evidencing such
     LASMO ADSs must be delivered pursuant to the procedure for book-entry
     transfer set out in paragraph 12(c) of Part B of Appendix I to this
     document (and a Book-Entry Confirmation received by the US Depositary in
     accordance with such procedures); or (ii) such holder must comply with the

                                       29
<PAGE>   32

     guaranteed delivery procedures set out in paragraph 12(h) of Part B of
     Appendix I to this document. Attention of LASMO ADS holders is drawn to
     paragraph 12(h)(iii) of this document.

(c)  Validity of acceptance

     Without prejudice to Part B of Appendix I to this Offer Document and
     subject to the City Code, Amerada Hess and Goldman Sachs reserve the right
     to treat as valid in whole or in part any acceptance of the Offer which is
     not entirely in order or which is not accompanied by (as applicable) the
     relevant transfer to escrow or the relevant share certificate(s), LASMO
     ADRs and/or other document(s) of title or which is received in a form or at
     a place or places other than as set out in this document or on the relevant
     Acceptance Form. In that event, no payment of cash or issue of new Amerada
     Hess Shares or, if applicable, issue of Loan Notes under the Offer will be
     required to be made until after the acceptance is entirely in order to
     Amerada Hess' satisfaction and (as applicable) the relevant transfer to
     escrow has been settled or the relevant share certificate(s) and/or other
     document(s) of title or indemnities satisfactory to Amerada Hess have been
     received by the UK Receiving Agent or the US Depositary, as the case may
     be.

(d) General

     No acknowledgement of receipt of any Acceptance Form, LASMO Share
     certificates, LASMO ADRs or other documents of title or documentation in
     respect of the Offer will be given.

     IF YOU ARE IN ANY DOUBT AS TO THE PROCEDURES FOR ACCEPTANCE, PLEASE CONTACT

19. RIGHTS OF WITHDRAWAL

Except to the extent of the exemptive relief which has been granted by the SEC,
the Offer is subject to the US tender offer rules applicable to securities
registered under the Exchange Act, as well as to the City Code. This has
necessitated a number of changes from the procedures which normally apply to
offers for companies governed by the City Code, including those applicable to
the rights of holders of LASMO Securities to withdraw their acceptance of the
Offer.

Under the Offer, holders of LASMO Securities will be able to withdraw their
acceptances at any time during the Initial Offer Period but will not have any
withdrawal rights during the Subsequent Offer Period, except in certain limited
circumstances (see paragraphs 4(c) and (d) of Part B of Appendix I to this
document).

The Offer will be deemed not to have been validly accepted in respect of any
LASMO Securities acceptances in respect of which have been validly withdrawn.
However, the Offer may be accepted again in respect of any withdrawn LASMO
Securities following one of the procedures described in paragraph 18 of this
letter at any time prior to expiry or lapse of the Offer.

Further details of these rights of withdrawal and the procedure for effecting
withdrawals are set out in paragraph 4 of Part B of Appendix I to this document.

20. SETTLEMENT

(a) Date of Payment

     The settlement procedure with respect to the Offer will be consistent with
     UK practice, which differs from US domestic tender offer procedures in
     certain material respects, particularly with regard to the date of payment.

     Subject to either the satisfaction, fulfilment or, to the extent permitted,
     waiver of all of the Conditions, settlement of consideration to accepting
     LASMO Shareholders and accepting holders of LASMO ADSs or their designated
     agents will be effected in the manner set out below:

                                       30
<PAGE>   33

     (i)    in the case of acceptances received complete in all respects by the
        end of the Initial Offer Period, within 14 calendar days of such date;
        or

     (ii)   in the case of acceptances received complete in all respects after
        such date but while the Offer remains open for acceptance, within 14
        calendar days of such receipt,

     in the manner set out below.

(b) LASMO Shares in uncertificated form (that is, in CREST)

     Where an acceptance relates to LASMO Shares in uncertificated form:

     (i)    the new Amerada Hess Shares to which the accepting LASMO Shareholder
        is entitled under the Offer will be issued to such shareholder in
        certificated form and share certificates and/or other documents of title
        will be despatched by post (or by such other method as may be approved
        by the Panel);

     (ii)   the cash consideration to which an accepting LASMO Shareholder is
        entitled will be paid by means of CREST by Amerada Hess procuring the
        creation of an assured payment obligation in favour of the accepting
        LASMO Shareholder's payment bank in respect of the cash consideration
        due, in accordance with the CREST assured payment arrangements; and

     (iii)  definitive certificates for any Loan Notes to which the accepting
        LASMO Shareholder is entitled will be despatched by post (or by such
        other method as may be approved by the Panel).

     Amerada Hess reserves the right to settle all or any part of the cash
     consideration referred to above, for all or any accepting LASMO
     Shareholder(s), in the manner referred to in paragraph (c) below, if, for
     any reason, it wishes to do so.

(c)  LASMO Shares in certificated form and LASMO ADSs

     Where an acceptance relates to LASMO Shares in certificated form or LASMO
     ADSs evidenced by LASMO ADRs, the new Amerada Hess Shares to which an
     accepting LASMO Securityholder is entitled under the Offer will be issued
     to the LASMO Securityholder in certificated form. Definitive certificates
     for the new Amerada Hess Shares and cheques for cash due and, where
     applicable, definitive certificates for any Loan Notes will be despatched
     by post (or by such other method as may be approved by the Panel).

(d) Lapsing of the Offer

     If by the relevant Closing Date the Conditions are not either satisfied,
     fulfilled or, to the extent permitted, waived, the Offer will lapse unless
     a later Closing Date is selected by Amerada Hess and: (i) in respect of
     LASMO Shares in certificated form and LASMO ADSs, the relevant share
     certificate(s), LASMO ADRs and/or other documents of title will be returned
     by post (or by such other method as may be approved by the Panel) within 14
     calendar days of the Offer lapsing to the person or agent whose name and
     address (outside Canada, Australia or Japan) is set out in Box 2 (or, if
     applicable, Box 9) of the Form of Acceptance or to the person or agent
     whose name and address (outside Canada, Australia or Japan) is set out in
     the Letter of Transmittal (as applicable) or, if none is set out, to the
     name and address of the person who is the first named holder at his or her
     registered address; (ii) in respect of LASMO Shares in uncertificated form
     (that is, in CREST), the UK Receiving Agent will, immediately after the
     lapsing of the Offer (or within such longer period as the Panel may permit,
     not exceeding 14 calendar days after the lapsing of the Offer), give
     transfer from escrow instructions to CRESTCo to transfer all relevant LASMO
     Shares held in escrow balances and in relation to which it is the escrow
     agent for the purposes of the Offer to the original available balances of
     the holders of LASMO Shares concerned; and (iii) in respect of LASMO ADSs
     delivered by book-entry transfer into the US Depositary's account at a
     Book-Entry Transfer Facility, LASMO ADSs will be credited to an account
     maintained at the appropriate Book-Entry Transfer Facility.

     Further information on the lapsing of the Offer is set out in paragraph 8
     of Part B of Appendix I to this document.

                                       31
<PAGE>   34

(e) General

     All documents and remittances sent by, to or from LASMO Securityholders or
     their appointed agents will be sent at their own risk.

     All mandates, instructions and other instruments in force immediately
     before the Offer becomes unconditional relating to holdings of LASMO
     Securities will, unless and until revoked, continue in force in relation to
     payments and notices in respect of new Amerada Hess Shares and under the
     Loan Notes issued under the Offer in each case insofar as relevant. If a
     LASMO Securityholder has existing Amerada Hess Shares, the mandates,
     instructions and instruments in force for the existing Amerada Hess Shares
     will supersede the mandates, instructions and instruments for the LASMO
     Securities.

(f)  Currency of cash consideration

     Instead of receiving cash consideration in pounds sterling, LASMO
     Shareholders who so wish may elect to receive US dollars on the basis that
     the cash amount payable in pounds sterling to which such holder would
     otherwise be entitled pursuant to the terms of the Offer will be converted,
     without charge, from pounds sterling to US dollars at the exchange rate
     obtainable by the relevant payment agent (either the UK Receiving Agent or
     the US Depositary) on the spot market in London at approximately noon
     (London time) on the date the cash consideration is made available by
     Amerada Hess to the relevant payment agent for delivery in respect of the
     relevant LASMO Shares. A LASMO Shareholder may receive such amount on the
     basis set out above only in respect of the whole of his holding of LASMO
     Shares in respect of which he accepts the Offer. LASMO Shareholders may not
     elect to receive both pounds sterling and US dollars.

     Holders of LASMO ADSs are entitled under the terms of the Offer to receive
     the cash element of the consideration in pounds sterling. The pounds
     sterling consideration available to holders of LASMO ADSs is the same, per
     LASMO Share, as that offered to LASMO Shareholders. To facilitate the
     settlement of the Offer, unless they elect to receive pounds sterling,
     holders of LASMO ADSs will receive consideration converted into US dollars
     as described above, as if such holders of LASMO ADSs had elected to receive
     US dollars.

     Consideration in US dollars may be inappropriate for LASMO Securityholders
     other than persons in the US and holders of LASMO ADSs.

     If you are a LASMO Shareholder and you wish to elect to receive cash
     consideration in US dollars instead of pounds sterling under the Offer, you
     should complete the appropriate box of the Form of Acceptance in addition
     to taking the actions described in paragraph 18 above.

     If you are a holder of LASMO ADSs and you wish to elect to receive cash
     consideration in pounds sterling instead of US dollars under the Offer, you
     should complete the appropriate box of your Letter of Transmittal in
     addition to taking the actions described in paragraph 18 above.

     THE ACTUAL AMOUNT OF US DOLLARS RECEIVED WILL DEPEND UPON THE EXCHANGE RATE
     PREVAILING ON THE BUSINESS DAY ON WHICH FUNDS ARE MADE AVAILABLE TO THE
     RELEVANT PAYMENT AGENT BY AMERADA HESS. LASMO SECURITYHOLDERS SHOULD BE
     AWARE THAT THE US DOLLAR/POUND STERLING EXCHANGE RATE WHICH IS PREVAILING
     ON THE DATE ON WHICH AN ELECTION IS MADE OR DEEMED TO BE MADE TO RECEIVE US
     DOLLARS AND ON THE DATES OF DESPATCH AND RECEIPT OF PAYMENT MAY BE
     DIFFERENT FROM THAT PREVAILING ON THE BUSINESS DAY ON WHICH FUNDS ARE MADE
     AVAILABLE TO THE RELEVANT PAYMENT AGENT BY AMERADA HESS. IN ALL CASES,
     FLUCTUATIONS IN THE US DOLLAR/POUNDS STERLING EXCHANGE RATE ARE AT THE RISK
     OF ACCEPTING LASMO SECURITYHOLDERS WHO ELECT OR ARE TREATED AS HAVING
     ELECTED TO RECEIVE THEIR CONSIDERATION IN US DOLLARS. NEITHER AMERADA HESS
     NOR ANY OR ITS ADVISERS OR AGENTS SHALL HAVE ANY RESPONSIBILITY WITH
     RESPECT TO THE ACTUAL AMOUNT OF CASH CONSIDERATION PAYABLE OTHER THAN IN
     POUNDS STERLING.

21. UNITED KINGDOM TAXATION

Information on the application of current UK tax law and Inland Revenue practice
applicable to LASMO Shareholders who accept the Offer is contained in paragraph
14 of Appendix VI to this document.

                                       32
<PAGE>   35

22. UNITED STATES FEDERAL TAXATION

Information on the application of current US federal tax law applicable to LASMO
Securityholders who accept the Offer is contained in paragraph 15 of Appendix VI
to this document.

HOLDERS OF LASMO SECURITIES ARE URGED TO CONSULT THEIR INDEPENDENT PROFESSIONAL
ADVISER IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES AS TO THE US AND UK TAX
CONSEQUENCES, AS WELL AS THE EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.

23. OVERSEAS LASMO SECURITYHOLDERS

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.
The attention of LASMO Securityholders who are citizens or residents of
jurisdictions outside the United Kingdom or the United States is drawn to
paragraph 9 of Part B of Appendix I of this document and to the relevant
provisions of the Acceptance Form.

The Offer, including the Loan Note Alternative, is not being made, directly or
indirectly, in or into Canada, Australia or Japan. Accordingly, any accepting
LASMO Securityholder who is unable to give the representations and warranties
set out in paragraphs 11(b) and 12(i)(ii)(dd) (as applicable) of Part B of
Appendix I to this document may be deemed not to have accepted the Offer.

The Loan Notes which may be issued pursuant to the Offer will not be listed on
any stock exchange and 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 or into 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 and 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 Note Alternative
will not be made into the United States or available to LASMO Securityholders in
the United States or to US persons outside the United States.

24. COMPULSORY ACQUISITION AND APPLICATION FOR DE-LISTING OF LASMO SECURITIES

If all of the Conditions are either satisfied, fulfilled or, to the extent
permitted, waived and Amerada Hess has acquired or contracted to acquire,
pursuant to the Offer or otherwise, at least 90 per cent. in nominal value of
the LASMO Shares to which the Offer relates, before the end of the four month
period provided by the Companies Act, Amerada Hess will be entitled, and
intends, to acquire the remaining LASMO Shares (including LASMO Shares
represented by LASMO ADSs) on the same terms as the Offer pursuant to the
compulsory acquisition procedure set out in sections 428 to 430F of the
Companies Act (see paragraph 11 of Appendix VI and Appendix VII to this
document).

When the Offer becomes or is declared unconditional in all respects, Amerada
Hess intends to procure the making of an application by LASMO for the removal of
LASMO Shares from the Official List of the UK Listing Authority and for the
cancellation of trading in LASMO Shares on the London Stock Exchange's market
for listed securities and also for the de-listing of LASMO ADSs and LASMO Shares
(the LASMO Shares do not trade on the NYSE and are listed on the NYSE only in
connection with the ADS program) from the NYSE. It is anticipated that
cancellation of listing from the Official List and cancellation of trading on
the London Stock Exchange will take effect no earlier than 20 business days
after the Offer becomes or is declared unconditional in all respects. De-listing
would significantly reduce the liquidity and marketability of any LASMO
Securities not assented to or tendered in the Offer. Amerada Hess will make an
announcement at least 20 business days prior to the cancellation of listing from
the Official List and the cancellation of trading on the London Stock Exchange
specifying the exact date upon which LASMO Shares will be de-listed. While it is
anticipated that cancellation of both listings will take place at the same time,
cancellation of the listing of the LASMO ADSs on the NYSE could take effect
earlier than cancellation of the listing and trading of the LASMO Shares on the
Official List of the UK Listing Authority and the London Stock Exchange,
respectively.

                   CONDITIONS AND FURTHER TERMS OF THE OFFER

PART A -- CONDITIONS OF THE OFFER

The Offer, which will be made by Amerada Hess on its own behalf in the United
States and by Goldman Sachs on behalf of Amerada Hess elsewhere, will be subject
to the following conditions:

(a) valid acceptances being received (and not, where permitted, withdrawn) by
     not later than 3.00 pm (London time), 10.00 am (New York City time), on
        --   2000 (or such later time(s) and/or date(s) as Amerada Hess may,
     subject to the rules of the City Code or with the consent of the Panel and
     in accordance with the Exchange Act, decide) in respect of not less than 90
     per cent. (or such lesser percentage as Amerada Hess may decide) in nominal
     value of the LASMO Shares (including LASMO Shares represented by LASMO
     ADSs) to which the Offer relates, provided that this condition will not be
     satisfied unless Amerada Hess (together with any of its wholly-owned
     subsidiaries and, to the extent that Amerada Hess so elects with the
     consent of the Panel, Methodplan) shall have acquired or agreed to acquire,
     whether pursuant to the Offer or otherwise, LASMO Shares (including LASMO
     Shares represented by LASMO ADSs) carrying, in aggregate, more than 50 per
     cent. of the voting rights then exercisable at general meetings of LASMO
     (excluding, to the extent that Amerada Hess so elects with the consent of
     the Panel, voting rights attached to the Methodplan Shares), including for
     this purpose (to the extent, if any, required by the Panel) any such voting
     rights attaching to any LASMO Shares (including LASMO Shares represented by
     LASMO ADSs) which are unconditionally allotted or issued before the Offer
     becomes or is declared unconditional as to acceptances, whether pursuant to
     the exercise of any outstanding conversion or subscription rights or
     otherwise and, for this purpose:

     (i)    the expression "LASMO Shares to which the Offer relates" shall be
        construed in accordance with sections 428 to 430F of the Companies Act;
        and

     (ii)   LASMO Shares which have been unconditionally allotted shall be
        deemed to carry the voting rights which they will carry upon issue;

     Registration Statement having been declared effective;

(c)  insofar as the Offer or any matter arising therefrom constitutes a
     concentration with a Community dimension within the scope of Council
     Regulation (EEC) 4064/89, as amended (the "Regulation"), the European
     Commission indicating in terms satisfactory to Amerada Hess that it does
     not intend to initiate proceedings under Article 6(1)(c) of the Regulation
     either in relation to the proposed acquisition of the whole of the LASMO
     business or in relation to those parts of the LASMO business over which it
     retains jurisdiction following its decision to make a referral of any part
     of the proposed acquisition to a competent authority of any Member State of
     the European Union under Article 9(1) of the Regulation;

(d) insofar as the Offer or any matter arising therefrom is not a concentration
     with a Community dimension or is such a concentration but is referred in
     whole or part to the competent authority of the UK under Article 9(1) of
     the Regulation, it being indicated in terms satisfactory to Amerada Hess,
     that it is not the intention of the Secretary of State for Trade and
     Industry to refer the Offer or any matter arising therefrom to the
     Competition Commission;

(e) all filings which Amerada Hess considers appropriate having been made and
     all or any applicable waiting periods (including any extensions thereof)

     terminated (as appropriate) in respect of the Offer and the proposed
     acquisition of LASMO by Amerada Hess;

(f)  the information supplied to Amerada Hess by LASMO prior to the release of
     the Announcement with respect to the number of LASMO Shares in issue and

     supplied and continuing to be accurate in all respects while the Offer
     remains open for acceptance;

     other person or body in any jurisdiction having decided to take,
     instituted, implemented or threatened any action, proceedings, suit,
     investigation or enquiry, or made, proposed or enacted, any statute,
     regulation or order or taken any other steps and there continuing not to be
     outstanding any statute, regulation, order or other such matter which in

        Group taken as a whole or the LASMO Group taken as a whole respectively;

     (iv)  require any member of the Amerada Hess Group or any member of the
        LASMO Group to offer to acquire any shares or any other securities in
        any of LASMO's subsidiaries or in any entity in which any member of the
        LASMO Group has a substantial interest owned by any third party where
        such interest would be material in the context of the Amerada Hess Group
        or the LASMO Group, as the case may be;

     (v)   otherwise affect the business, profits or prospects of the LASMO
        Group (taken as a whole) in a manner which is material and adverse;

           Amerada Hess, from all appropriate governments, governmental,
           quasi-governmental, supranational, statutory or regulatory bodies or
           trade agencies, professional associations or courts, or persons or

           contractual arrangements; and

     (ii)   all Authorisations necessary to carry on the business of any member
        of the Wider LASMO Group (the absence of which Authorisation would have
        a material adverse effect on the LASMO Group taken as a whole) or to
        enable any member of the Wider LASMO Group to continue to enjoy without
        material interruption or modification the benefit of its interests in
        its material assets, remaining in full force and effect and there being
        no intimation of an intention to revoke or not to renew any of such
        Authorisations and all necessary statutory or regulatory obligations in
        any jurisdiction having been complied with in all material respects;

(i)  there being no provision of any arrangement, agreement, licence or other
     instrument to which any member of the Wider LASMO Group is a party, or by
     or to which any such member or any of their assets may be bound, entitled
     or be subject to and which, in consequence of the proposed acquisition of
     any shares in, or control of, LASMO by Amerada Hess or otherwise, would or
     might, to an extent which is material in the context of the LASMO Group
     taken as a whole, result in:

                                       I-2
<PAGE>   39

     (i)    any monies borrowed by any such member becoming capable of being
        declared repayable prior to their stated maturity or the ability of any
        such member to incur any indebtedness being withdrawn or inhibited;

     (ii)   the creation of any mortgage, charge or other security interest over
        the whole or any part of the business, property or assets of any such
        member or any such security (whenever arising or having arisen) becoming
        enforceable;

        terminated or adversely modified or any action being taken or any
        obligation arising thereunder;

        ordinary course of business;

     (v)   the interests or business of any such member in or with any firm or
        body or, in the case of a business, person or any arrangements relating
        to such interest or business, being terminated or modified or affected;

     and no event having occurred which, under any provision of any such
     arrangement, agreement, licence or other instrument, could result in any of
     the events or circumstances which are referred to in paragraphs (i) to (v)
     of this condition (i) in any case where such result would be material in
     the context of the LASMO Group taken as a whole;

        and save for options granted, and for any LASMO Shares allotted upon

        Wider LASMO Group, in each case which could have a material adverse
        effect on the LASMO Group taken as a whole;

     (iii)  no contingent liability having arisen which might be likely
        materially and adversely to affect the LASMO Group;

(l)    Amerada Hess not having discovered:

     (i)    that the financial or business information concerning the LASMO
        Group, as contained in the information disclosed at any time publicly or
        directly to Amerada Hess by any member of the LASMO Group contains a
        material misrepresentation of fact or omits to state a fact necessary to

        Group taken as a whole; and

(m)  Amerada Hess not having discovered:

     (i)    that any information supplied to Amerada Hess by LASMO with respect
        to the nature of LASMO's interests in its material assets is or has
        become materially inaccurate or misleading or that any member of the
        Wider LASMO Group has become or may become subject to a material
        interruption or modification of its ability to enjoy the benefit of its
        interests in its material assets;

     (ii)   that any past or present member of the Wider LASMO Group has not
        complied with all applicable laws of any relevant jurisdiction relating
        to environmental matters which non-compliance would be likely to give

        Wider LASMO Group which is material in the context of the LASMO Group
        taken as a whole;

     (iii)  that there is, or is likely to be, any material liability (whether

     (iv)  that circumstances exist whereby a person or class of persons would
        be likely to have any claim or claims in respect of any product or
        process of manufacture or materials used therein now or previously
        manufactured, sold or carried out by any past or present member of the
        Wider LASMO Group which claim or claims would be likely materially and
        adversely to affect any member of the Wider LASMO Group and which is
        material in the context of the LASMO Group taken as a whole.

The Offer will lapse unless the Conditions have been determined by Amerada Hess
in its reasonable opinion to have been and to remain satisfied, fulfilled or (if
capable of waiver) waived by 3.00 pm (London time), 10.00 am (New York City
time), on    --   2000 or any later Closing Date applicable from time to time.

                                       I-4
<PAGE>   41

The Acceptance Condition shall be capable of being satisfied or being treated as
satisfied only at the time when all of the other Conditions shall have been
either satisfied, fulfilled or (to the extent permitted) waived unless Amerada
Hess, with the consent of the Panel, shall otherwise decide. The Offer is
capable of becoming unconditional in all respects only on a Closing Date, unless
Amerada Hess in compliance with US securities laws otherwise decides. Following
the delivery by Amerada Hess to the US Depositary of a notice of acceptance in
respect of LASMO ADSs tendered pursuant to a Letter of Transmittal, Amerada Hess
shall be deemed to have acquired or agreed to acquire the tendered LASMO ADSs
and the LASMO Shares represented by such LASMO ADSs.

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 the Conditions by a date earlier than the
applicable Closing Date for its satisfaction notwithstanding that any other
Condition of the Offer may on or before such date have been satisfied, fulfilled
or, to the extent permitted, waived and/or that there are no circumstances
indicating that any such Conditions may not be capable of satisfaction or
fulfilment.

Amerada Hess reserves the right, subject to the consent of the Panel, to extend
the time allowed under the rules of the City Code for satisfaction of the
Acceptance Condition and accordingly for the satisfaction, fulfilment or, where
permitted, waiver of other Conditions, and thus, to extend the duration of the
Initial Offer Period.

The LASMO Shares held by Methodplan may not be voted by Methodplan as a result
of the operation of section 23 of the Companies Act. Amerada Hess has elected
and has received the consent of the Panel in respect of such election, in
accordance with the terms of the Acceptance Condition, that any LASMO Shares
held by Methodplan at the date the Acceptance Condition is treated as satisfied
will not be counted for the purposes of the Acceptance Condition in determining
(a) whether or not Amerada Hess and/or any other relevant person has acquired or
agreed to acquire, whether pursuant to the Offer or otherwise, LASMO Shares
(including LASMO Shares represented by LASMO ADSs) carrying in aggregate more
than 50 per cent. of the voting rights then exercisable at general meetings of
LASMO or (b) the LASMO Shares (including LASMO Shares represented by LASMO ADSs)
of which LASMO (or any other relevant person) is required to acquire (or agree
to acquire) such percentage. This election will not otherwise affect the
determination, for the purposes of the Acceptance Condition, of whether valid
acceptances have been received in respect of not less than 90 per cent. (or such
lesser percentage as Amerada Hess may decide) in nominal value of the LASMO
Shares (including LASMO Shares represented by LASMO ADSs) to which the Offer
relates.

If Amerada Hess is required by the Panel to make an offer for LASMO Securities
under the provisions of Rule 9 of the City Code, Amerada Hess may make such
alterations to the Conditions, including the Acceptance Condition, as are
necessary to comply with the provisions of that Rule.

Unless the Panel otherwise agrees, the Offer will lapse if (a) the acquisition
of LASMO is referred to the Competition Commission or (b) the European
Commission, pursuant to Council Regulation (EEC) 4064/89, as amended ("the
Regulation"), initiates proceedings in connection with any aspect of the
proposed acquisition under Article 6(1)(c) of the Regulation or makes a referral
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 3.00 pm (London time), 10.00 am (New York City time) on    --   ,
2000 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 NYSE is drawn to certain UK dealing
disclosure requirements following the Announcement. The Announcement commenced
an offer period under the City Code which is published and administered by the
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 end of the Initial Offer Period.

                                       I-5
<PAGE>   42

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 and to the Panel.

Member firms should advise those of their clients who wish to deal in the
relevant securities of LASMO and Amerada Hess, 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 7638
0129, fax number +44 (0)20 7256 9386).

PART B -- FURTHER TERMS OF THE OFFER

The following further terms apply, unless the contrary is expressed or the
context requires otherwise, to the Offer and the Loan Note Alternative.

Unless the context otherwise requires, any reference in Part B of this Appendix
I and in the Acceptance Form:

     (i)    to the "Offer" will mean the Offer and will include any revision,
        variation or renewal thereof or extension thereto and any election in
        connection therewith;

     (ii)   to the Offer "becoming unconditional as to acceptances" means the
        Acceptance Condition becoming or being determined by Amerada Hess to be
        satisfied;

     (iii)  to the Offer "becoming unconditional in all respects" means all
        Conditions being fulfilled, satisfied or, to the extent permitted,
        waived; and

     (iv)  to "acceptances of the Offer" shall include deemed acceptances of the
        Offer.

1.  ACCEPTANCE PERIOD

(a) The Offer is initially open for acceptance until 3.00 pm (London time),
    10.00 am (New York City time), on    --   2000. Amerada Hess reserves the
    right (but will not be obliged, other than as may be required by the City
    Code or the Exchange Act and the rules and regulations thereunder) at any
    time or from time to time to extend the Offer after such time and, in such
    event, will make a public announcement of such extension in the manner
    described in paragraph 3 below. If all of the Conditions are not satisfied,
    fulfilled or, to the extent permitted, waived by Amerada Hess as of 3.00 pm
    (London time), 10.00 am (New York City time), on    --   2000, the Offer
    will lapse and no LASMO Securities will be purchased under it unless Amerada
    Hess extends the Offer by specifying a later Closing Date. In these
    circumstances, Amerada Hess currently intends to extend the Offer for a
    period to be determined at its discretion. However, there can be no
    assurance that Amerada Hess will extend the Offer in such circumstances. If
    the Conditions have been satisfied, fulfilled or waived by such time (being
    the end of the Initial Offer Period), the Offer will be extended for a
    Subsequent Offer Period of at least 14 calendar days. The Offer is capable
    of becoming unconditional in all respects only on a Closing Date, unless
    Amerada Hess, in compliance with US securities laws, otherwise decides.

(b) Although no revision is envisaged, if the Offer is revised, the Offer will
    be extended, if necessary, for a period of at least 14 calendar days (or
    such lesser period as may be permitted by the Panel and in accordance with
    the Exchange Act) from the date on which written notification of the revised
    Offer is posted to LASMO Securityholders. Except with the consent of the
    Panel, no revision of the Offer may be made after [DAY 46] or, if later, the
    date which is 14 calendar days before the last date on which the Offer can
    become unconditional as to acceptances.

(c)  Except with the consent of the Panel, the Offer, whether revised or not,
     shall not be capable of becoming unconditional as to acceptances (nor,
     therefore, unconditional in all respects) and, accordingly, the Initial
     Offer Period is not (except with the consent of the Panel) capable of being
     extended, after midnight (London time), 7.00 pm (New York City time), on
     [DAY 60] (or any other earlier time or date beyond which Amerada Hess has
     stated that the Offer will not be extended and has not withdrawn that
     statement). If all of the Conditions are not satisfied, fulfilled or, to
     the extent permitted, waived at such time or any later Closing Date to
     which the Initial Offer Period has been duly extended, the Offer will lapse
     unless the Panel agrees otherwise. If the Offer lapses for any reason, the
     Offer shall cease to be capable of further acceptance and Amerada Hess and
     LASMO Securityholders shall cease to be bound by prior acceptances. Amerada
     Hess reserves the right, with the permission of the Panel and in accordance
     with the Exchange Act, to extend the final date for acceptance of the Offer
     and for the satisfaction of the Acceptance Condition and all the other
     Conditions and, accordingly, the Initial Offer Period.

(d) Amerada Hess reserves the right (but will not be obliged) at any time and
    from time to time to extend the Subsequent Offer Period for any period it
    chooses after such time. If Amerada Hess states that the Offer will remain
    open until further notice, Amerada Hess will give not less than 14 calendar
    days' notice in writing to LASMO Securityholders who have not accepted the
    Offer before closing the Subsequent Offer Period.

                                       I-7
<PAGE>   44

(e) If a competitive situation arises (as determined by the Panel) after a "no
    increase" and/or "no extension" statement has been made by or on behalf of
    Amerada Hess in relation to the Offer, Amerada Hess may, if it has
    specifically reserved the right to do so at the time the statement is made
    (or otherwise with the consent of the Panel), withdraw the statement and be
    free to increase or, as the case may be, to extend the Offer provided that
    it complies with the requirements of the City Code and the Exchange Act and
    in particular that:

     (i)    it announces the withdrawal as soon as possible and in any event
        within four business days after the date of the announcement of the
        competing offer or other competitive situation;

     (ii)   it notifies LASMO Securityholders in writing of the withdrawal (or,
        in the case of LASMO Securityholders with registered addresses outside
        the United Kingdom or United States, or whom Amerada Hess reasonably
        believes to be nominees, custodians or trustees holding LASMO Securities
        for such persons, by announcement in the United Kingdom and United
        States) at the earliest practicable opportunity; and

     (iii)  any LASMO Securityholders who accepted the Offer after the date of
        the "no increase" or "no extension" statement are given a right of
        withdrawal in accordance with paragraph 4(d) of Part B of this Appendix
        below. Withdrawal rights will apply in any event during the Initial
        Offer Period.

     Amerada Hess may, if it has specifically reserved the right to do so at the
     time the statement is made, choose not to be bound by the terms of a "no
     increase" or "no extension" statement if it would otherwise prevent the
     posting of an increased or improved offer (either as to the value or nature
     of the consideration offered or otherwise) which is recommended for
     acceptance by the board of directors of LASMO, or in other circumstances
     permitted by the Panel.

2.  ACCEPTANCE CONDITION

(a) For the purposes of determining whether the Acceptance Condition has been
    satisfied, Amerada Hess may, except as otherwise agreed by the Panel, only
    take into account acceptances received in respect of or purchases of LASMO
    Securities made in respect of which all relevant documents are received by
    the UK Receiving Agent or the US Depositary by 3.00 pm (London time), 10.00
    am (New York City time) on    --   2000 or such later Closing Date as may be
    specified but, except with the consent of the Panel, not later than 1.00 pm
    on [DAY 60] or, in each case, any earlier Closing Date beyond which Amerada
    Hess has stated that the Offer will not be extended (unless the Conditions
    are at that Closing Date satisfied, fulfilled or, to the extent permitted,
    waived) and has not withdrawn that statement.

    If, with the consent of the Panel, the latest time and date at which the
    Offer may become unconditional as to acceptances (and thus the latest time
    at which it may become unconditional in all respects) is extended beyond
    1.00 pm (London time), 8.00 am (New York City time) on [DAY 60], so that the
    Initial Offer Period is accordingly extended, acceptances received and
    purchases made in respect of which the relevant documents are received by
    the UK Receiving Agent or the US Depositary after 1.00 pm (London time),
    8.00 am (New York City time) on or after that later date may only be taken
    into account with the agreement of the Panel, except where the City Code
    permits otherwise.

(b) Except as otherwise agreed by the Panel:

     (i)    an acceptance of the Offer in respect of LASMO Securities will only
        be treated as valid for the purposes of the Acceptance Condition if the
        requirements of Note 4 and, if applicable, Note 6 to Rule 10 of the City
        Code are satisfied in respect of it;

     (ii)   a purchase of LASMO Securities by Amerada Hess or its nominee or (if
        Amerada Hess is required by the Panel to make an offer for LASMO
        Securities under Rule 9 of the City Code) by a person acting in concert
        with Amerada Hess or its nominee, will only be treated as valid for the
        purposes of the Acceptance Condition if the requirements of Note 5 and,
        if applicable, Note 6 to Rule 10 of the City Code are satisfied in
        respect of it; and

     (iii)  before the Offer may become unconditional as to acceptances the UK
        Receiving Agent must issue a certificate to Amerada Hess or Goldman
        Sachs which states the number of LASMO Securities in respect of which
        acceptances have been received and not validly withdrawn and the number
        of LASMO Securities otherwise acquired, whether before or during the
        Offer
                                       I-8
<PAGE>   45

        Period, which comply with the provisions of the City Code referred to in
        this paragraph 2(b). Copies of such certificate will be sent to the
        Panel as soon as possible after it is issued.

(c)  For the purpose of determining whether the Acceptance Condition has been
     satisfied, Amerada Hess shall be entitled to take into account only those
     LASMO Securities carrying voting rights which have been unconditionally
     allotted or issued, whether pursuant to the exercise of conversion or
     subscription rights or otherwise, before the determination takes place and
     written notice of the allotment or issue of which, containing all relevant
     details, has been received before that time by the UK Receiving Agent or
     the US Depositary on behalf of Amerada Hess from LASMO or its agents at one
     of the addresses set out at the back of this document. Notification by
     e-mail, telex or facsimile transmission does not constitute written notice
     for this purpose.

(d) In accordance with applicable SEC rules, at least five business days prior
     to any reduction in the percentage of LASMO Shares (including LASMO Shares
     represented by LASMO ADSs) required to satisfy the Acceptance Condition,
     Amerada Hess will announce that it has reserved the right so to reduce the
     Acceptance Condition. The announcement will be made through a press release
     designed to inform LASMO Securityholders in the United Kingdom and
     elsewhere and by placing an advertisement in a newspaper of national
     circulation in the United States. Such announcement will state the exact
     percentage to which the Acceptance Condition may be reduced, will state
     that such a reduction is possible but that Amerada Hess need not declare
     its actual intentions until it is required to do so under the City Code and
     will contain language advising LASMO Securityholders to withdraw their
     LASMO Securities if their willingness to accept the Offer would be affected
     by a reduction of the Acceptance Condition. Amerada Hess will not make such
     an announcement unless it believes that there is a significant possibility
     that a sufficient number of acceptances will be received to permit the
     Acceptance Condition to be satisfied at such reduced level and that the
     other Conditions will be satisfied, fulfilled or, to the extent permitted,
     waived at such time (which in any event will not be a date other than a
     Closing Date). LASMO Securityholders who are not willing to accept the
     Offer if the Acceptance Condition is reduced to a level lower than 90 per
     cent. should not accept the Offer until it becomes or is declared
     unconditional as to acceptances (which may be at a level lower than 90 per
     cent.) and/or be prepared to withdraw their acceptances promptly following
     an announcement by Amerada Hess of its reservation of the right to reduce
     the Acceptance Condition. Upon any announcement being made that the
     percentage of LASMO Shares (including LASMO Shares represented by LASMO
     ADSs) required to satisfy the Acceptance Condition may be reduced, the
     Offer shall not be capable of becoming or being declared unconditional in
     all respects until the expiry of at least five business days thereafter.
     LASMO Securityholders will be able to accept the Offer for at least five
     business days after a reduction of the Acceptance Condition either during
     the Initial Offer Period or the Subsequent Offer Period.

3.  ANNOUNCEMENTS

(a) Without prejudice to paragraph 4 below, by 8.00 am (London time) in the
     United Kingdom and 8.00 am (New York City time) in the United States on the
     business day (the "RELEVANT DAY") after the day on which the Offer is due
     to expire or on which all Conditions become or are declared to have been
     either satisfied, fulfilled or, to the extent permitted, waived or on which
     the Offer is revised or is extended (or such later time or date as the
     Panel may agree), Amerada Hess will make an appropriate announcement and
     inform the London Stock Exchange and the Dow Jones News Service. In the
     announcement Amerada Hess will state (unless otherwise permitted by the
     Panel) the total number of LASMO Securities and rights over LASMO
     Securities (as nearly as practicable):

     (i)    for which acceptances of the Offer have been received, showing the
        extent, if any, to which such acceptances have been received from
        persons acting or deemed to be acting in concert with Amerada Hess for
        the purposes of the Offer;

     (ii)   held by or on behalf of Amerada Hess or any person acting or deemed
        to be acting in concert with Amerada Hess for the purposes of the Offer
        before the Offer Period; and

     (iii)  acquired or agreed to be acquired by or on behalf of Amerada Hess or
        any person acting or deemed to be acting in concert with Amerada Hess
        for the purposes of the Offer during the Offer Period;

     and the announcement will specify the percentage of the issued share
     capital of LASMO represented by each of these figures.

                                       I-9
<PAGE>   46

(b) In calculating the number of LASMO Securities represented by acceptances and
     purchases, Amerada Hess may only include acceptances and purchases if they
     could be counted towards fulfilling the Acceptance Condition under Notes 4,
     5 and 6 to Rule 10 of the City Code, unless the Panel agrees otherwise.
     Subject to this, Amerada Hess may include or exclude, for announcement
     purposes, acceptances and purchases not in all respects in order or which
     are subject to verification.

(c)  Any decision to extend the Offer may be made at any time up to, and will be
     announced by, 8.00 am (London time) in the United Kingdom and 8.00 am (New
     York City time) in the United States on the relevant day (or such later
     time and/or date as the Panel may agree). If the Offer is not yet
     unconditional in all respects (so that the Initial Offer Period has not yet
     expired) the announcement will state the next Closing Date and the Initial
     Offer Period will therefore be extended to that Closing Date or, if the
     Offer has become unconditional in all respects (with the result that the
     Initial Offer Period has ended on that Closing Date), the announcement may
     state that the Offer will remain open for a Subsequent Offer Period until
     further notice or until a further specified date not less than 14 calendar
     days after the end of the Initial Offer Period.

(d) In this Appendix, a reference to the making of an announcement or the giving
     of notice by or on behalf of Amerada Hess includes the release of an
     announcement by Amerada Hess' public relations consultants or Goldman
     Sachs, in each case on behalf of Amerada Hess, to the press and the
     delivery by hand or telephone, e-mail, telex or facsimile or other
     electronic transmission of an announcement to the London Stock Exchange and
     the Dow Jones News Service, as the case may be. An announcement made
     otherwise than to the London Stock Exchange and the Dow Jones News Service
     will be notified simultaneously to the London Stock Exchange and the Dow
     Jones News Service.

(e) Without limiting the manner in which Amerada Hess may choose to make any
     public announcement and, subject to Amerada Hess' obligations under
     applicable law (including Rules 14d-4(c) and 14d-6(c) under the Exchange
     Act relating to Amerada Hess' obligations to disseminate promptly public
     announcements concerning material changes to the Offer), Amerada Hess will
     have no obligation to publish, advertise or otherwise communicate any such
     public announcement other than by making a release to the London Stock
     Exchange and the Dow Jones News Service.

4.  RIGHTS OF WITHDRAWAL

(a) Except as provided by this paragraph 4, acceptances and elections are
     irrevocable.

(b) LASMO Securities in respect of which valid acceptances have been received
     may be withdrawn pursuant to the procedures set out below at any time
     during the Initial Offer Period and in certain other circumstances
     described below. LASMO Securities in respect of which valid acceptances
     have been received during the Initial Offer Period and that are not validly
     withdrawn during the Initial Offer Period and LASMO Securities tendered
     during the Subsequent Offer Period may not be withdrawn. Holders of LASMO
     Securities will not have withdrawal rights during the Subsequent Offer
     Period, except in certain limited circumstances described below.

(c)  If Amerada Hess announces that the Acceptance Condition has been satisfied
     all the other Conditions will also be satisfied, fulfilled or, to the
     extent permitted, waived and the Initial Offer Period will terminate.
     Withdrawal rights will also terminate at that time, unless Amerada Hess
     then fails to comply by 3.30 pm (London time), 10.30 am (New York City
     time), on the relevant day (as defined in paragraph 3(a) of this Part B)
     (or such later time and/or date as the Panel may agree) with any of the
     other requirements specified in paragraph 3(a) of Part B of this Appendix,
     in which case a LASMO Securityholder who has previously accepted the Offer
     may withdraw his acceptance of the Offer by written notice in compliance
     with paragraphs 4(e) and (f) of Part B of this Appendix (if appropriate)
     given by post or by hand to the UK Receiving Agent or the US Depositary at
     the addresses set out at the back of this document. Subject to paragraph
     1(c) of Part B of this Appendix, this right of withdrawal may be terminated
     not less than eight calendar days after the relevant day by Amerada Hess
     confirming that the Offer is still unconditional, and complying with the
     other requirements specified in paragraph 3(a) of Part B of this Appendix.
     If that confirmation is given, the first period of 14 days referred to in
     paragraph 1(d) of Part B of this Appendix will start on the date of that
     confirmation and compliance.

                                      I-10
<PAGE>   47

(d) If a "no increase" and/or "no extension" statement is withdrawn in
     accordance with paragraph 1(e) of Part B of this Appendix, a person who
     accepts the Offer after the date of the statement may withdraw his
     acceptance in the manner set out in paragraph 4(c) of Part B of this
     Appendix during the period of eight calendar days after the date Amerada
     Hess posts the notice of the withdrawal of that statement to LASMO
     Securityholders.

(e) To be effective, a written notice of withdrawal must be received, subject to
     paragraphs 4(c) and (d) of Part B of this Appendix I, by the end of the
     Initial Offer Period by the party (either the UK Receiving Agent or the US
     Depositary) to whom the Acceptance Form was originally returned by the
     relevant LASMO Securityholder and must specify the name of the person from
     whom the acceptance was received, the number of LASMO Securities to be
     withdrawn and (if share certificates or LASMO ADRs, as the case may be,
     have been provided) the name of the registered holder of the relevant LASMO
     Securities, if different from the name of the person from whom the
     acceptance was received.

(f)  In respect of LASMO ADSs, if LASMO ADRs have been delivered or otherwise
     identified to the US Depositary, then, prior to the physical release of
     such LASMO ADRs, the serial numbers shown on such LASMO ADRs must be
     submitted and, unless the LASMO ADSs evidenced by such LASMO ADRs have been
     delivered by an Eligible Institution, the signatures on the notice of
     withdrawal must be guaranteed by an Eligible Institution. If interests in
     LASMO ADSs evidenced by LASMO ADRs have been delivered pursuant to the
     procedures for book-entry transfer set out in paragraph 12(c) of Part B of
     this Appendix, any notice of withdrawal must specify the name and number of
     the account at the appropriate Book-Entry Transfer Facility to be credited
     with the withdrawn LASMO ADSs and must otherwise comply with such
     Book-Entry Transfer Facility's procedures.

(g) In this paragraph 4, "written notice" (including any letter of appointment,
     direction or authority) means notice in writing bearing the original
     signature(s) of the relevant accepting LASMO Securityholder(s) or his or
     their agent(s) duly appointed in writing (evidence of whose appointment is
     produced with the notice in a form satisfactory to Amerada Hess).
     Notification by telex or facsimile or other electronic transmission or
     copies will not be sufficient to constitute written notice. Any notice
     which is postmarked in or otherwise appears to Amerada Hess or its agents
     to have been sent from Canada, Australia or Japan may not be treated as
     valid.

(h) Withdrawals of LASMO Securities in respect of which valid acceptances have
     been received may not be rescinded (without Amerada Hess' consent) and any
     LASMO Securities properly withdrawn and in respect of which valid
     acceptances have not been received thereafter will thereafter be deemed not
     to be the subject of a valid acceptance for the purposes of the Offer.
     Withdrawn LASMO Securities may be subsequently the subject of a valid
     acceptance, however, by following one of the procedures described in either
     paragraph 10, 11 or 12 of Part B of this Appendix, as the case may be, at
     any time whilst the Offer remains open.

(i)  All questions as to the validity (including time of receipt) of any notice
     of withdrawal will be determined by Amerada Hess, whose determination
     (except as required by the Panel) will be final and binding. None of
     Amerada Hess, LASMO, Goldman Sachs, the US Depositary, the UK Receiving
     Agent or any other person will be under any duty to give notification of
     any defects or irregularities in any notice of withdrawal or incur any
     liability for failure to give such notification or for any determination
     under this paragraph (i).

5.  MIX AND MATCH ELECTION

(a) Elections for the Mix and Match Election will only be accepted in respect of
     whole numbers of LASMO Securities. The number of LASMO Securities in
     respect of which a Mix and Match Election is made represents the number of
     LASMO Securities in respect of which the LASMO Securityholder wishes to
     receive either all cash or, as the case may be, all new Amerada Hess
     Shares, as consideration under the Offer.

(b) Valid elections for new Amerada Hess Shares made by LASMO Securityholders in
     excess of their basic entitlement to new Amerada Hess Shares will be
     satisfied in full where sufficient new Amerada Hess Shares are available as
     a result of other accepting LASMO Securityholders validly making elections
     for cash in excess of their basic entitlements under the Offer, thereby
     releasing new Amerada Hess Shares to which they would otherwise be entitled
     under the Offer.

                                      I-11
<PAGE>   48

     If, under the Mix and Match Election, the number of new Amerada Hess Shares
     made available as a result of valid elections for cash in excess of the
     basic entitlement thereto is insufficient to satisfy in full all valid
     elections for new Amerada Hess Shares in excess of LASMO Securityholders'
     basic entitlements thereto, then such excess elections will be scaled down
     on a pro rata basis and the balance of the consideration will be satisfied
     in cash or, if an election for the Loan Note Alternative is available and
     is made, in Loan Notes in accordance with the basic terms of the Offer.

(c)  Valid elections for cash made by LASMO Securityholders in excess of their
     basic entitlement to cash will be satisfied in full where sufficient cash
     is available as a result of other accepting LASMO Securityholders validly
     making elections for new Amerada Hess Shares in excess of their basic
     entitlement under the Offer, thereby releasing cash to which they would
     otherwise be entitled under the Offer.

     If, under the Mix and Match Election, the amount of cash made available as
     a result of valid elections for new Amerada Hess Shares in excess of the
     basic entitlement thereto is insufficient to satisfy in full all valid
     elections for cash in excess of LASMO Securityholders' basic entitlements
     thereto, then such elections will be scaled down on a pro rata basis and
     the balance of the consideration will be satisfied in accordance with the
     basic terms of the Offer.

(d) To the extent that valid Mix and Match Elections can be satisfied in
    accordance with sub-paragraphs (b) and (c) above, LASMO Securityholders will
    receive new Amerada Hess Shares instead of cash and vice versa based upon
    the value of an Amerada Hess Share as at the close of business on the NSYE
    on the most recent NYSE trading day prior to the date the relevant LASMO
    Securityholder's entitlement under the Mix and Match Election falls to be
    determined. The sterling equivalent of the value of an Amerada Hess Share as
    at such date will be determined at the US$ to L exchange rate at that time,
    as determined by Goldman Sachs.

(e) If a LASMO Securityholder eligible to elect for the Loan Note Alternative
    elects for the Loan Note Alternative as well as for the Mix and Match
    Election then, to the extent that the consideration he receives is modified
    as a result of such elections not being satisfied in full in accordance with
    paragraph (b) above, the Mix and Match Election will be deemed to take
    effect before his election for the Loan Note Alternative.

(f)  Although the Offer will remain open for a Subsequent Offer Period of at
     least 14 calendar days after the Closing Date on which the Offer becomes or
     is declared unconditional in all respects (at the end of the Initial Offer
     Period), the Mix and Match Election will remain open until but not beyond
     3.00 pm (London time), 10.00 am (New York City time) on the date falling
     five calendar days after the date on which the Offer becomes or is declared
     unconditional in all respects.

(g) No Election for the Mix and Match Election will be valid unless both a valid
    acceptance of the Offer and a valid election of the Mix and Match Election,
    duly completed in all respects and (i) accompanied by all relevant share
    certificate(s), LASMO ADRs and/or other document(s) of title in respect of
    LASMO Securities in certificated form, or, (ii) if the LASMO Securities to
    which the acceptance relates are in uncertificated form, a settlement of a
    transfer to escrow instruction in favour of the UK Receiving Agent as escrow
    agent in relation to LASMO Shares or an Agent's Message to the US Depositary
    in relation to LASMO ADSs in accordance with the procedures set out in this
    document, are duly received by the time and date on which the Mix and Match
    Election closes.

(h) In the event that a LASMO Securityholder purports to elect for both
    additional cash and additional new Amerada Hess Shares under the Mix and
    Match Election, both purported elections shall be deemed to be void, and
    such LASMO Securityholder shall be deemed to have accepted the Offer on its
    basic terms in respect of all the LASMO Securities to which the relevant
    Acceptance Form relates or is deemed to relate.

(i)  If any Acceptance Form which includes an election for the Mix and Match
     Election is either received after the time and date upon which the Mix and
     Match Election closes or is received before such time and date but is not,
     and is not deemed to be, valid or complete in all respects at such time and
     date, such election shall, for all purposes, be void and the LASMO
     Securityholder purporting to make such election shall not, for any purpose,
     be entitled to receive any variation of consideration under the Mix and
     Match Election, but such acceptance, if otherwise valid, shall, subject to
     the provisions of paragraph (j) below, be deemed to be an acceptance of the
     Offer in respect of the number of LASMO Securities indicated in the
     relevant Acceptance Form and the relevant LASMO
                                      I-12
<PAGE>   49

     Securityholder will, upon the Offer becoming unconditional in all respects
     be entitled to receive the basic consideration due under the Offer in
     respect thereof.

(j)  The Mix and Match Election will lapse if the Offer lapses or expires. An
     election under the Mix and Match Election may only be made in respect of
     LASMO Securities for which the Offer is validly accepted. LASMO
     Securityholders who do not make a Mix and Match Election will receive the
     basic terms of the Offer. Mix and Match Elections must be made at the same
     time as the acceptances of the Offer to which they relate, on the relevant
     Acceptance Form at the time of acceptance and not subsequently.

(k)  Amerada Hess reserves the right to limit the extent to which elections
     under the Mix and Match Election (or any subsequent mix and match election)
     will be capable of being satisfied by cash and/ or Amerada Hess Shares
     released by opposite elections by other LASMO Securityholders insofar as it
     determines this to be necessary or desirable with a view to ensuring that
     the aggregate number of Amerada Hess Shares and the aggregate amount of
     cash payable to all LASMO Securityholders do not exceed the levels which
     would apply in the event of full acceptance of the Offer with a single
     Closing Date for the Mix and Match Election, whether as a result of the
     operation of the provisions of Sections 429 to 430F of the Companies Act
     (which permit compulsory acquisition of outstanding shares following a
     takeover offer) or otherwise.

6.  THE LOAN NOTE ALTERNATIVE

(a) As an alternative to all or part of the cash consideration to which they are
    otherwise entitled under the Offer (including under the Mix and Match
    Election), LASMO Shareholders (other than US persons and certain
    shareholders not resident in the United Kingdom) who validly accept the
    Offer may elect to receive Loan Notes to be issued by Amerada Hess on the
    basis described below.

(b) The Loan Note Alternative is conditional upon all of the Conditions becoming
    or being declared satisfied, fulfilled or, to the extent permitted, waived
    and will remain open for as long as the Offer remains open for acceptance.
    Under the Loan Note Alternative, Amerada Hess agrees with each LASMO
    Shareholder (other than US persons and certain shareholders not resident in
    the United Kingdom) who validly accepts the Offer and validly elects for the
    Loan Note Alternative to issue to each such LASMO Shareholder a Loan Note,
    credited as fully paid, of L1 nominal value, in respect of each L1 cash
    consideration to which such LASMO Shareholder would otherwise be entitled
    under the Offer (including any additional cash to which a LASMO Shareholder
    becomes entitled under the Mix and Match Election). 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 L2 million in aggregate nominal amount of Loan Notes
    or such smaller amount as Amerada Hess may, in its absolute discretion,
    decide. If insufficient elections are received, the LASMO Shareholders who
    have validly accepted the Offer and elected to receive Loan Notes will
    (unless the board of Amerada Hess otherwise determines) receive cash in
    accordance with the terms of the Offer (including the Mix and Match
    Election).

(c)  No election for the Loan Note Alternative will be valid unless both a valid
     acceptance of the Offer and a valid election for the Loan Note Alternative,
     duly completed in all respects and accompanied by, if appropriate, all
     relevant share certificates and/or other document(s) of title, are duly
     received by the time and date on which the Loan Note Alternative closes.

(d) If any acceptance of the Offer which includes an election for the Loan Note
    Alternative is not, and is not deemed to be, valid or complete in all
    respects at such time, such election shall for all purposes be void and the
    holder(s) of LASMO Shares purporting to make such election shall not, for
    any purpose, be entitled to receive the Loan Note Alternative, but any such
    acceptance which is otherwise valid shall be deemed to be an acceptance of
    the Offer (without the Loan Note Alternative) for the number of LASMO Shares
    which are the subject of the acceptance and the holder(s) of LASMO Shares
    will, on the Offer becoming unconditional in all respects, be entitled to
    receive the cash consideration due under the Offer in accordance with the
    terms of the Offer.

(e) The insertion of a number in Box 4 on the Form of Acceptance shall, subject
    to the other terms of the Offer, be treated in respect of the relevant
    number of LASMO Shares as an election for the Loan Note Alternative.

(f)  An election for the Loan Note Alternative will not be valid unless the Form
     of Acceptance is completed correctly in all respects and is received in
     accordance with paragraphs 10 and 11 below.
                                      I-13
<PAGE>   50

(g) The Loan Notes will be issued, credited as fully paid, in amounts and
    integral multiples of L1 nominal value and fractional entitlements will be
    disregarded and not paid.

(h) 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 Note Alternative will not be made into the United States or
    available to LASMO Securityholders who are US persons.

(i)  Goldman Sachs has advised that, based on market conditions on  -- December
     2000 (the latest practicable date prior to the posting of this document),
     the value of the Loan Notes (had they been in issue on that day) would not
     have been less than 95 pence per L1 in nominal value.

(j)  Further details of the Loan Note Alternative are set out in Appendix II
     below.

7.  REVISION OF THE OFFER AND/OR THE LOAN NOTE ALTERNATIVE

(a) Although no revision is envisaged, if the Offer (in its original or
    previously revised form(s)) is revised (either in terms or conditions or in
    the value or form of the consideration offered or otherwise) and whether or
    not the Mix and Match Election and/or the Loan Note Alternative (in their
    original or any previously revised form(s)) are revised, the benefit of the
    revised Offer will, subject as provided in paragraphs 7(b), 7(c), 7(e) and 9
    of Part B of this Appendix, be made available to a LASMO Securityholder who
    has validly accepted the Offer (in its original or any revised form(s)) and
    not validly withdrawn such acceptance (a "PREVIOUS ACCEPTOR") if the revised
    Offer represents, on the date on which it is announced (on such basis as
    Goldman Sachs may consider appropriate), an improvement, or no diminution,
    in the value of the consideration offered compared with the consideration or
    terms previously offered. The acceptance by or on behalf of a Previous
    Acceptor of the Offer (in its original or any revised form(s)) will, subject
    as provided in paragraphs 7(b), 7(c), 7(e) and 9 of Part B of this Appendix,
    be deemed an acceptance of the revised Offer and will constitute the
    appointment of and direction to any director of Amerada Hess or of Goldman
    Sachs as his attorney and/or agent with authority, whether or not he shall
    have elected for the Mix and Match Election and/or the Loan Note
    Alternative:

     (i)    to accept the revised Offer on his behalf;

     (ii)   if the revised Offer includes alternative forms of consideration, to
            make on his behalf elections for and/or accept the alternative forms
            of consideration on his behalf in the proportions the attorney
            and/or agent in his absolute discretion thinks fit; and

     (iii)  to execute on his behalf and in his name any further documents and
            take such further actions (if any) as may be required to give effect
            to those elections or acceptances.

     In making any election and/or acceptance, the attorney and/or agent will
     take into account the nature of any previous acceptance or election made by
     or on behalf of the Previous Acceptor and such other facts or matters as he
     may reasonably consider relevant. The attorney and/or agent shall not be
     liable to any LASMO Securityholder or any other person in making any such
     election and/or acceptance or in making any determination in respect
     thereof. In this paragraph, the expression the "offer" shall, and shall be
     deemed to, mean and include the Offer and/or the Mix and Match Election
     and/or the Loan Note Alternative and/or all or any alternative forms of
     consideration to be given under the Offer and any combination or choice of
     the Offer and/or the Mix and Match Election and/or the Loan Note
     Alternative and/or all or any alternative forms of consideration.

(b) The deemed acceptance and/or election referred to in paragraph 7(a) of Part
    B of this Appendix will not apply and the power of attorney and authorities
    conferred by that paragraph will not be exercised if, as a result, the
    Previous Acceptor would (on such basis as Goldman Sachs may consider
    appropriate) receive less in aggregate in consideration under the Offer than
    he would have received in aggregate in consideration as a result of his
    acceptance of the Offer in the form originally accepted by him or on his
    behalf (unless the Previous Acceptor has previously agreed in writing to
    receive less in aggregate consideration).

                                      I-14
<PAGE>   51

(c)  The deemed acceptance and/or election referred to in paragraph 7(a) of Part
     B of this Appendix will not apply and the power of attorney and the
     authorities conferred by that paragraph will be ineffective in the case of
     a Previous Acceptor who lodges, within 14 calendar days of the posting of
     the document containing the revised Offer and/or any revised or other
     alternative, an Acceptance Form (or any other form issued on behalf of
     Amerada Hess) in which he validly elects to receive consideration under the
     revised Offer in some other manner than that set out in his original
     acceptance.

(d) Amerada Hess and Goldman Sachs reserve the right to treat an executed
    Acceptance Form relating to the Offer (in its original or any previously
    revised form(s)) which is received (or dated) after the announcement of any
    revised Offer as a valid acceptance of the revised Offer (and where
    applicable a valid election for the alternative forms of consideration).
    That acceptance will constitute an authority in the terms of paragraph 7(a)
    of Part B of this Appendix on behalf of the relevant LASMO Securityholder.

(e) If Amerada Hess makes a material change in the terms of the Offer or if it
    waives a material Condition of the Offer prior to the Closing Date at the
    end of the Initial Offer Period, Amerada Hess will disseminate additional
    tender offer materials and extend the Offer to the extent required by Rules
    14d-4(d), 14d-6(c) and 14e-1 under the Exchange Act. The minimum period
    during which an offer must remain open following material changes in the
    terms of the Offer, other than a change in price or a change in the
    percentage of securities sought, will depend upon the facts and
    circumstances then existing, including the materiality of the changes. With
    respect to a change in price or, subject to certain limitations, a change in
    the percentage of securities sought, a minimum of ten business days is
    generally required to allow for adequate dissemination to Securityholders.
    Any reduction of the Acceptance Condition will be effected and announced in
    the manner described in paragraph 2(d) of Part B of this Appendix.

8.  GENERAL

(a) If the Offer lapses, neither Amerada Hess nor any person acting, or deemed
    to be acting, in concert with Amerada Hess for the purposes of the Offer nor
    any of their respective affiliates may, pursuant to the City Code, make an
    offer (whether inside or outside the United Kingdom) for LASMO Securities
    for a period of one year following the date of such lapse, except with the
    permission of the Panel.

(b) If the Offer lapses or is withdrawn, Acceptance Forms, LASMO share
    certificates, LASMO ADRs and other documents of title will be returned by
    post (or by such other method as the Panel may approve) within 14 calendar
    days of the Offer lapsing, at the risk of the LASMO Securityholder in
    question, to the person or agent whose name and address (outside Canada,
    Australia or Japan) is set out in the relevant box on the Acceptance Form
    or, if none is set out, to the first-named holder at his registered address
    (outside Canada, Australia or Japan) or, in the case of LASMO ADSs delivered
    by book-entry transfer into the US Depositary's account at a Book-Entry
    Transfer Facility pursuant to the procedures set forth in paragraph 12(c) of
    Part B of this Appendix, such LASMO ADSs will be credited within such period
    to an account maintained at the appropriate Book-Entry Transfer Facility.

(c)  The UK Receiving Agent will, immediately after the Offer lapses (or within
     such longer period as the Panel may permit, not exceeding 14 days of the
     Offer lapsing) instruct CRESTCo to transfer all LASMO Shares held in escrow
     balances and in relation to which it is the escrow agent for the purposes
     of the Offer to the original available balances of the relevant LASMO
     Shareholders.

(d) Except with the consent of the Panel:

     (i)    settlement of the consideration to which any LASMO Securityholder is
            entitled under the Offer will be fully implemented in accordance
            with the terms of the Offer without regard to any lien, right of
            set-off, counterclaim or other analogous right to which Amerada Hess
            or Goldman Sachs may otherwise be, or claim to be, entitled against
            that LASMO Securityholder; and

     (ii)   settlement of the consideration will be effected in the manner
            prescribed in paragraph 20 of the Letter from Goldman Sachs not
            later than 14 calendar days after the later of the date on which the
            Offer becomes wholly unconditional and the date of receipt of a
            valid and complete Acceptance Form from such holder of LASMO
            Securities. Without prejudice to paragraph 8(g) of Part B of this
            Appendix I, LASMO Securities delivered pursuant to the procedures
            de-
                                      I-15
<PAGE>   52

        scribed in paragraph 12(h) of Part B of this Appendix may be treated as
        valid and complete for these purposes at the discretion of Amerada Hess
        whether or not the additional procedures in paragraph 12(h)(i)(cc) shall
        have been complied with.

(e) The terms, provisions, instructions and authorities contained in the
    Acceptance Forms also constitute part of the terms of the Offer. A word or
    expression defined in this document has the same meaning when used in an
    Acceptance Form, unless the context requires otherwise. The provisions of
    this Appendix I shall be deemed to be incorporated in the Acceptance Forms.

(f)  Any omission or failure to despatch this document, the Acceptance Forms,
     any other documents relating to the Offer or any notice required to be
     despatched under the terms of the Offer to, or any failure to receive the
     same by, any person to whom the Offer is, or should be, made will not in
     any way invalidate the Offer or create any implication that the Offer has
     not been made to any such person. Subject to the provisions of paragraph 9
     of Part B of this Appendix, the Offer is made to any LASMO Securityholder
     to whom this document and the Acceptance Forms or any related document may
     not have been despatched or who may not receive such documents, and these
     persons may collect the relevant documents from the UK Receiving Agent, the
     US Depositary or the Information Agent.

(g) Subject to the City Code, Amerada Hess and Goldman Sachs reserve the right
    to treat as valid in whole or in part any acceptance of the Offer if
    received by the UK Receiving Agent or the US Depositary or otherwise on
    behalf of Amerada Hess which is not entirely in order or in the correct form
    or which is not accompanied by (as applicable) the relevant transfer to
    escrow or the relevant share certificates, LASMO ADRs and/or other documents
    of title which are received by them in a form or at a place or places other
    than as set out in this document or the relevant Acceptance Form. In that
    event, no issue of new Amerada Hess Shares or payment of cash, or, if
    applicable, issue of Loan Notes under the Offer will be made until after the
    acceptance is entirely in order and (as applicable) the relevant transfer to
    escrow has settled or the relevant share certificate(s), LASMO ADRs and/or
    other document(s) of title or indemnities satisfactory to Amerada Hess have
    been received by the UK Receiving Agent or the US Depositary, as the case
    may be.

(h) If all of the Conditions have been either satisfied, fulfilled or, to the
    extent permitted, waived and Amerada Hess has acquired or contracted to
    acquire, pursuant to the Offer or otherwise, at least 90 per cent. in
    nominal value of the LASMO Shares (including LASMO Shares represented by
    LASMO ADSs) to which the Offer relates, before the end of the four month
    period provided by the Companies Act, Amerada Hess will be entitled, and
    intends, to acquire the remaining LASMO Securities on the same terms as the
    Offer pursuant to the compulsory acquisition procedure set out in sections
    428 to 430E of the Companies Act (see paragraph 11 of Appendix VI and
    Appendix VII to this document). When the Offer becomes or is declared
    unconditional in all respects, Amerada Hess intends to procure the making of
    an application by LASMO for the removal of LASMO Shares from the Official
    List of the UK Listing Authority and for the cancellation of trading in
    LASMO Shares on the London Stock Exchange market for listed securities and
    also for the de-listing of LASMO ADSs and LASMO Shares from the NYSE. It is
    anticipated that cancellation of listing from the Official List and
    cancellation of trading on the London Stock exchange will take effect no
    earlier than 20 business days after the Offer becomes or is declared
    unconditional in all respects. De-listing would significantly reduce the
    liquidity and marketability of any LASMO Securities with respect to which
    valid acceptances were not received in the Offer. Amerada Hess will make an
    announcement at least 20 business days prior to cancellation of listing from
    the Official List and the cancellation of trading on the London Stock
    Exchange specifying the exact date upon which LASMO Shares will be
    de-listed. While it is anticipated that cancellation of both listings will
    take place at the same time, cancellation of the listing of the LASMO ADSs
    and LASMO Shares on the NYSE could take place earlier than cancellation of
    the listing and trading of the LASMO Shares on the Official List of the UK
    Listing Authority and the London Stock Exchange, respectively.

(i)  All powers of attorney, appointments of agents and authorities on the terms
     conferred by or referred to in this Appendix or in the Acceptance Forms are
     given by way of security for the performance of the obligations of the
     relevant LASMO Securityholders and are irrevocable in accordance with
     section 4 of the Powers of Attorney Act 1971, except in the circumstances
     where the donor of the power of attorney or authority validly withdraws his
     acceptance in accordance with paragraph 4 of Part B of this Appendix I.

                                      I-16
<PAGE>   53

(j)  No acknowledgement of receipt of any Acceptance Form, share certificate,
     LASMO ADR or other document of title will be given. All communications,
     notices, certificates, LASMO ADRs, documents of title and remittances to be
     delivered by, and sent to or from, LASMO Securityholders (or their
     designated agent(s)) will be delivered or sent at their own risk.

(k)  If the Offer becomes unconditional in all respects, all mandates,
     instructions and instruments in force immediately before the Offer becomes
     unconditional in all respects relating to holdings of LASMO Securities
     will, unless/until revoked, continue in force in relation to payments and
     notices in respect of new Amerada Hess Shares and under Loan Notes issued
     under the Offer in each case insofar as relevant. If a LASMO Securityholder
     has existing Amerada Hess Shares, the mandates, instructions and
     instruments in force for the existing Amerada Hess Shares will supersede
     the mandates and instructions for the LASMO Securities.

(l)  Amerada Hess and Goldman Sachs reserve the right to notify any matter,
     including the making of the Offer, to all or any LASMO Securityholders:

     (i)    with a registered address outside the United Kingdom and the United
            States; or

     (ii)   whom Amerada Hess or Goldman Sachs knows to be a custodian, trustee
            or nominee holding LASMO Securities for persons who are citizens,
            residents or nationals of jurisdictions outside the United Kingdom
            and the United States,

     by announcement in the United Kingdom to the London Stock Exchange and in
     the United States to the Dow Jones News Service or in any other appropriate
     manner or by paid advertisement in newspapers published and circulated in
     the United Kingdom and the United States. Such notice will be deemed to
     have been sufficiently given, despite any failure by a LASMO Securityholder
     to receive or see that notice. A reference in this document to a notice or
     the provision of information in writing by or on behalf of Amerada Hess is
     to be construed accordingly. No such document will be sent to an address in
     Canada, Australia or Japan.

(m) The Offer is made at 3.00 pm (London time), 10.00 am (New York City time) on
     [DAY 0] 2000 and is capable of acceptance from and after that time. The
     Offer is made in the United States by Amerada Hess. The terms and
     conditions set forth in the letter from Goldman Sachs apply equally to such
     offer. Acceptance Forms and copies of this document may be collected from
     the UK Receiving Agent, the US Depositary or the Information Agent at one
     of the addresses set out at the back of this document.

(n) This Offer has been announced by means of an advertisement in the Financial
     Times (United Kingdom edition only) and The Wall Street Journal on [DAY 0]
     2000.

(o) The Offer, all acceptances of the Offer, all elections in respect of it and
     the contract to which it gives rise, are governed by and will be construed
     in accordance with English law. Execution by or on behalf of a LASMO
     Securityholder of an Acceptance Form constitutes his irrevocable submission
     to the jurisdiction of the courts of England in relation to all matters
     arising in connection with the Offer. However, the conduct of the Offer is
     also subject to US federal securities laws and the securities laws of the
     States and other jurisdictions in the US in which the Offer is being made
     if, and to the extent, applicable to the Offer.

(p) References in paragraphs 10, 11 and 12(i) of this Part B to a LASMO
     Securityholder, a holder of LASMO Shares and a holder of LASMO ADSs will
     include references to the person or persons executing the Acceptance Form
     and in the event of one or more than one such person executing an
     Acceptance Form, such provisions shall apply to them jointly.

(q) In relation to any acceptance of the Offer in respect of a holding of LASMO
     Shares which are in uncertificated form, Amerada Hess reserves the right to
     make such alterations, additions or modifications as may be necessary or
     desirable to give effect to any purported acceptance of the Offer, whether
     in order to comply with the facilities or requirements of CREST or
     otherwise, provided such alterations, additions or modifications are
     consistent with the requirements of the City Code or are otherwise made
     with the consent of the Panel.

(r)  All references in this Appendix I to any statute or statutory provision
     shall include a statute or statutory provision which amends, consolidates
     or replaces the same (whether before or after the date hereof).

                                      I-17
<PAGE>   54

(s)  Fractions of new Amerada Hess Shares will not be allocated or issued to
     accepting LASMO Securityholders but will be aggregated and sold in the
     market and the net proceeds of sale distributed pro rata to LASMO
     Securityholders entitled to them. Such payments will be made in sterling,
     the proceeds having been converted from US dollars at a prevailing exchange
     rate chosen by Amerada Hess at the relevant time. However, individual
     entitlements to amounts of less than L5.00 will not be paid to holders of
     LASMO Securities but will be retained for the benefit of the enlarged
     Amerada Hess Group.

(t)  References in this document to the Offer being accepted by LASMO
     Securityholders or to acceptances in respect of the LASMO Securities shall
     be construed to mean, in the case of LASMO ADSs, the tender of such ADSs
     using a Letter of Transmittal, save where the context otherwise requires.

(u) 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, 1,344,328,323 LASMO Shares had been issued
     (including LASMO Shares represented by LASMO ADSs) and 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 to adjust the Offer consideration, by
     reducing rateably the aggregate number of Amerada Hess Shares to be issued
     under the Offer, if any issue of LASMO Shares in excess of these amounts
     would mean that Amerada Hess would otherwise be obliged to issue more than
     17.18 million new Amerada Hess Shares under the Offer or pursuant to the
     statutory compulsory acquisition arrangements under Section 429 of the
     Companies Act. In that event, LASMO Securityholders will instead be
     entitled to receive cash at a rate of L43.37 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
     trading day prior to the Announcement, translated into sterling at the rate
     of US$1.4484: L1.00.

(v)  In so far as a dividend or other distribution was proposed, declared, made
     or payable in respect of a LASMO Security 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 Security will be
     reduced by the amount of the dividend and/or distribution except in so far
     as the LASMO Security 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
     Securityholder in respect of a LASMO Security will be reduced by the amount
     of any such reduction of the consideration payable in respect of that LASMO
     Security 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.

(w) All LASMO Securities 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 6 November 2000.

(x)  The new Amerada Hess Shares will rank pari passu in all respects with
     existing Amerada Hess Shares, including the right to any dividends and
     other distributions declared, paid or made by reference to a record date
     after the date on which they are issued. For the avoidance of doubt, LASMO
     Securityholders will not be entitled to the dividend of Amerada Hess
     expected to be declared in December 2000 and paid on or about 3 January
     2001.

9.  OVERSEAS LASMO SECURITYHOLDERS

(a) The making of the Offer (including the Loan Note Alternative) in, or to
     certain persons resident in, or nationals or citizens of, jurisdictions
     outside the United Kingdom or the United States (and the availability of
     Loan Notes to such persons or US persons) or to their nominees or trustees
     may be prohibited or affected by the laws of the relevant jurisdiction.
     LASMO Securityholders who are persons, citizens, residents or nationals of
     jurisdictions outside the United Kingdom and the United States (or, in the
     case of Loan Notes, outside the United Kingdom only) should inform
     themselves about and observe any applicable legal requirements. It is the
     responsibility of such LASMO Securityholders wishing to accept the Offer or
     the Loan Note Alternative to satisfy themselves as to
                                      I-18
<PAGE>   55

     the full observance of the laws of the relevant jurisdiction in connection
     with the Offer. This includes the obtaining of any governmental, exchange
     control or other consents which may be required, compliance with other
     necessary formalities needing to be observed and the payment of any issue,
     transfer or other taxes due in that jurisdiction by whomsoever payable and
     Amerada Hess and Goldman Sachs and any persons acting on their behalf will
     be fully indemnified and held harmless by any LASMO Securityholder for whom
     Amerada Hess or Goldman Sachs are required to pay any issue, transfer or
     other taxes. The Loan Note Alternative is not being made available to LASMO
     Securityholders who are US persons, or to certain other overseas persons.

(b) The Offer (including the Loan Note Alternative) is not being made, directly
     or indirectly, in or into Canada, Australia or Japan or by use of the mails
     of, or by any means or instrumentality of interstate or foreign commerce
     of, or of any facility of a national securities exchange of Canada,
     Australia or Japan. This includes, but is not limited to, e-mail, facsimile
     transmission, telex and telephone. Accordingly, copies of this document,
     the Acceptance Forms, and any related Offer Documents are not being, and
     must not be mailed, forwarded or otherwise distributed or sent in, into or
     from Canada, Australia or Japan. Persons receiving such documents
     (including, without limitation, custodians, nominees and trustees) must not
     distribute, mail or send them in, into or from Canada, Australia or Japan
     or use the Canadian, Australian or Japanese (or, if electing for the Loan
     Note Alternative, Australian, Canadian, Japanese or US) mails or any such
     means, instrumentality or facility for any purpose directly or indirectly
     in connection with the Offer, and so doing may invalidate any related
     purported acceptance of the Offer. Envelopes containing Acceptance Forms in
     respect of the Offer must not be postmarked in Canada, Australia or Japan
     (or, if electing for the Loan Note Alternative, Australia, Canada, Japan or
     the US) or otherwise despatched from those jurisdictions and all acceptors
     must provide addresses outside Canada, Australia or Japan (and, if electing
     for the Loan Note Alternative, the US) for the receipt of the consideration
     to which they are entitled under the Offer or for the return of Acceptance
     Forms or documents of title.

(c)  Subject as provided below, a LASMO Securityholder will be deemed not to
     have accepted the Offer if:

     (i)    he cannot give the representations and warranties set out in
        paragraphs 11(b) and 12(i)(ii)(dd) of Part B of this Appendix;

     (ii)   he completes the relevant Box of the Acceptance Form with an address
        in Canada, Australia or Japan (or, if electing for the Loan Note
        Alternative, the US) or has a registered address in Canada, Australia or
        Japan (or, if electing for the Loan Note Alternative, the US) and in
        either case he does not insert in the relevant Box of the Acceptance
        Form the name and address of a person or agent outside Canada, Australia
        or Japan (and if electing for the Loan Note Alternative, the US) to whom
        he wishes the consideration to which he is entitled under the Offer to
        be sent;

     (iii)  he inserts in the relevant Box of the Acceptance Form the name and
        address of a person or agent in Canada, Australia or Japan (or, if
        electing for the Loan Note Alternative, Canada, Australia, Japan or the
        US) to whom he wishes the consideration to which he is entitled under
        the Offer to be sent; or

     (iv)  the Acceptance Form received from him is in an envelope postmarked
        in, or which otherwise appears to Amerada Hess or its agents to have
        been sent from, Canada, Australia or Japan (or, if electing for Loan
        Note Alternative, Canada, Australia, Japan or the US).

(d) If any person, despite the restrictions referred to in paragraph 9(b) of
     Part B of this Appendix and whether pursuant to a contractual or legal
     obligation or otherwise, forwards this document, the Acceptance Form or any
     related offering document in, into or from Canada, Australia or Japan or
     uses the mails or any means or instrumentality (including, without
     limitation, e-mail, facsimile transmission, telex and telephones) of
     interstate or foreign commerce of, or any facilities of a national
     securities exchange of Canada, Australia or Japan in connection with that
     forwarding, that person should:

     (i)    inform the recipient of that fact;

     (ii)   explain to the recipient that that action may invalidate any
        purported acceptance by the recipient; and

     (iii)  draw the attention of the recipient to this paragraph 9.
                                      I-19
<PAGE>   56

(e) If any written notice from a LASMO Securityholder withdrawing his acceptance
     in accordance with paragraph 4 of Part B of this Appendix is received in an
     envelope postmarked in, or which otherwise appears to Amerada Hess or its
     agents to have been sent from Canada, Australia or Japan, Amerada Hess
     reserves the right, in its absolute discretion, to treat that notice as
     invalid.

(f)  The provisions of this paragraph 9 and any other terms of the Offer
     relating to overseas holders of LASMO Securities may be waived, varied or
     modified as regards specific LASMO Securityholders or on a general basis by
     Amerada Hess in its sole discretion. Subject to this discretion, the
     provisions of this paragraph 9 supersede any terms of the Offer
     inconsistent with them. A reference in this paragraph 9 to a LASMO
     Securityholder includes the person or persons executing the Acceptance Form
     and, in the event of more than one person executing an Acceptance Form, the
     provisions of this paragraph 9 apply to them jointly and severally.

(g) The Loan Notes to be issued pursuant to the Loan Note Alternative will not
     be listed on any stock exchange and 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 or into 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.

     If in respect of a Form of Acceptance from any LASMO Shareholder the holder
     is unable or Amerada Hess believes the holder is unable to make the
     representations and warranties set out in paragraph 11(b), Amerada Hess
     reserves the right, in its absolute discretion, to ignore any election in
     that Form of Acceptance to receive Loan Notes and to treat it instead as an
     acceptance of the Offer for cash.

10. PROCEDURES FOR ACCEPTING THE OFFER IN RESPECT OF LASMO SHARES

(a) Holders of LASMO Shares will have received with this document a Form of
     Acceptance. This section should be read together with the Form of
     Acceptance. The provisions of this section shall be deemed to be
     incorporated in, and to form a part of, the Form of Acceptance. The
     instructions printed on the Form of Acceptance shall be deemed to form part
     of the terms of the Offer.

     If a holder of LASMO Shares holds LASMO Shares in both certificated and
     uncertificated form, he should complete a separate Form of Acceptance for
     each holding. Similarly, such holder should complete a separate Form of
     Acceptance for LASMO Shares held in uncertificated form, but under
     different member account IDs, and for LASMO Shares held in certificated
     form, but under different designations.

(b) To accept the Offer, any LASMO Shareholder, including any person in the US
     who holds LASMO Shares, wishing to accept the Offer in respect of all or
     any portion of such holder's LASMO Shares, should complete Box 1, check Box
     2 and, if applicable, complete Boxes 3A or B, 4, 7, 8 and 9A or B and, if
     such holder's LASMO Shares are in CREST, Box 7 on the Form of Acceptance
     should then be signed in accordance with the instructions printed on it.
     All LASMO Shareholders who are individuals should sign the Form of
     Acceptance in the presence of a witness who should also sign Box 6 in
     accordance with the instructions printed on it. Unless witnessed, an
     acceptance will not be valid.

(c)  An accepting LASMO Shareholder should return the completed, signed and
     witnessed Form of Acceptance, whether or not such LASMO Shares are in
     CREST, to the UK Receiving Agent (if such accepting LASMO Shareholder is
     not resident in the United States) or to the US Depositary (if such
     accepting LASMO Shareholder is a resident in the United States). The
     completed Form of Acceptance, together, if such holder's LASMO Shares are
     in certificated form, with his share certificate(s) and/or other
     document(s) of title, must be lodged with the UK Receiving Agent (if such
     accepting LASMO Shareholder is not resident in the United States) or the US
     Depositary (if such accepting LASMO Shareholder is a resident in the United
     States), as soon as possible, but in any event so as to arrive NOT LATER
     THAN 3.00 PM (LONDON TIME), 10.00 AM (NEW YORK CITY TIME) ON    --   .

     If you have any questions as to how to complete the Form of Acceptance,
     please contact the UK Receiving Agent on 0870 7020100, the US Depositary on
     +1 (212) 815 6156 or the Information Agent on +1 (212) 269 5550.

                                      I-20
<PAGE>   57

     A person in the US who holds LASMO Shares may submit the Form of
     Acceptance, together with his share certificates and/or other document(s)
     of title, to the US Depositary, who will receive such Form(s) of Acceptance
     and certificate(s) and/or other document(s) of title on behalf of the UK
     Receiving Agent. A Form of Acceptance contained in an envelope postmarked
     in Canada, Australia or Japan or otherwise appearing to Amerada Hess or its
     agents to have been sent from Canada, Australia or Japan may be rejected as
     invalid.

(d) If LASMO Shares are in uncertificated form, the holder should insert in Box
     [6] of the Form of Acceptance the participant ID and member account ID
     under which such LASMO Shares are held by him in CREST and otherwise
     complete and return the Form of Acceptance as described above. In addition,
     such holders should take (or procure to be taken) the action set out below
     to transfer the LASMO Shares in respect of which he wishes to accept the
     Offer to an escrow balance, specifying the UK Receiving Agent (in its
     capacity as a CREST participant under the participant ID referred to below)
     as the escrow agent, as soon as possible but in any event so that the
     transfer to escrow settles NOT LATER THAN 3.00 PM (LONDON TIME), 10.00 AM
     (NEW YORK CITY TIME) ON    --   2000.

(e) IF THE LASMO SHAREHOLDER IS A CREST SPONSORED MEMBER, HE SHOULD REFER TO HIS
     CREST SPONSOR BEFORE TAKING ANY ACTION. Such holder's sponsor will be able
     to confirm details of his participant ID and the member account ID under
     which his LASMO Shares are held. In addition, only his CREST sponsor will
     be able to send the TTE Instruction to CRESTCo in relation to his LASMO
     Shares.

(f)  The holder of such LASMO Shares should send (or, if he is a CREST sponsored
     member, procure that his CREST sponsor sends) a TTE Instruction to CRESTCo
     which must be property authenticated in accordance with CRESTCo's
     specifications and which must contain, in addition to the other information
     that is required for a TTE Instruction to settle in CREST, the following
     details:

     (i)    the number of LASMO Shares to be transferred to an escrow balance;

     (ii)   the member account ID of such LASMO Shareholder. This must be the
            same member account ID as the member account ID that is inserted in
            Box 7 of the Form of Acceptance;

     (iii)  the participant ID of such LASMO Shareholder. This must be the same
            participant ID as the participant ID that is inserted in Box 7 of
            the Form of Acceptance;

     (iv)  the participant ID of the escrow agent (the UK Receiving Agent in its
           capacity as a CREST receiving agent). This is 3RA43;

     (v)   the member account ID of the escrow agent. This is LASMO;

     (vi)  the Form of Acceptance Reference Number. This is the Form of
           Acceptance Reference Number that appears next to Box 7 on page 3 of
           the Form of Acceptance. This Reference Number should be inserted in
           the first eight characters of the shared note field on the TTE
           Instruction. Such insertion will enable the UK Receiving Agent to
           match the transfer to escrow to your Form of Acceptance. The holder
           of such shares should keep a separate record of this Form of
           Acceptance Reference Number for future reference;

     (vii)  the Intended Settlement Date. This should be as soon as possible and
            in any event not later than 3.00 pm (London time), 10.00 am (New
            York City time) on    --   2000;

     (viii) the Corporate Action Number for the Offer. This is allocated by
            CRESTCo and can be found by viewing the relevant Corporate Action
            Details in CREST; and

     (ix)  input with Standard Delivery instruction of 80.

(g) After settlement of the TTE Instruction, such LASMO Shareholder will not be
    able to access the LASMO Shares concerned in CREST for any transaction or
    charging purposes. If all of the Conditions are either satisfied, fulfilled
    or, to the extent permitted, waived, the escrow agent will transfer the
    LASMO Shares concerned to itself in accordance with paragraph 11(d) of Part
    B of this Appendix.

(h) Such LASMO Shareholder is recommended to refer to the CREST Manual published
    by CRESTCo for further information on the CREST procedures outlined above.
    For ease of processing, such holder is requested, wherever possible, to
    ensure that a Form of Acceptance relates to only one transfer to escrow.

                                      I-21
<PAGE>   58

(i)  If no Form of Acceptance Reference Number, or an incorrect Form of
     Acceptance Reference Number, is included on the TTE Instruction, Amerada
     Hess may treat any amount of LASMO Shares transferred to an escrow balance
     in favour of the escrow agent specified above from the participant ID and
     member account ID IDentified in the TTE Instruction as relating to any
     Form(s) of Acceptance which relate(s) to the same member account ID and
     participant ID (up to the amount of LASMO Shares inserted or deemed to be
     inserted on the Form(s) of Acceptance concerned).

(j)  Such LASMO Shareholder should note that CRESTCo does not make available
     special procedures, in CREST, for any particular corporate action. Normal
     system timings and limitations will therefore apply in connection with a
     TTE Instruction and its settlement. Such holder should therefore ensure
     that all necessary action is taken by him (or by his CREST sponsor) to
     enable a TTE Instruction relating to his LASMO Shares to settle prior to
     3.00 pm (London time), 10.00 am (New York City time) on    --   2000. In
     this connection such holder is referred in particular to those sections of
     the CREST Manual concerning practical limitations of the CREST system and
     timings.

(k)  Amerada Hess will make an appropriate announcement if any of the details
     contained in this paragraph 10 alter for any reason.

(l)  Normal CREST procedures (including timings) apply in relation to any LASMO
     Shares that are, or are to be, converted from uncertificated to
     certificated form, or from certificated to uncertificated form, during the
     course of the Offer (whether any such conversion arises as a result of a
     transfer of LASMO Shares or otherwise). LASMO Shareholders who are
     proposing so to convert any LASMO Shares are recommended to ensure that the
     conversion procedures are implemented in sufficient time to enable the
     person holding or acquiring the LASMO Shares as a result of the conversion
     to take all necessary steps in connection with an acceptance of the Offer
     (in particular, as regards delivery of share certificates or other
     documents of title or transfers to an escrow balance as described above)
     prior to 3.00 pm (London time), 10.00 am (New York City time) on
        --   2000.

(m) If the share certificate(s) and/or other document(s) of title is/are not
     readily available or is/are lost, the Form of Acceptance should
     nevertheless be completed, signed and sent as stated above to the UK
     Receiving Agent or the US Depositary so as to be received as soon as
     possible, but in any event no later than 3.00 pm (London time), 10.00 am
     (New York City time) on    --   2000, together with any share
     certificate(s) and/or other document(s) of title that is/are available,
     accompanied by a letter stating that the balance will follow or that the
     accepting holder has lost one or more of his share certificate(s) and/or
     other documents of title. If the share certificate(s) and/or other
     document(s) of title are lost, the accepting holder should request the
     registrar of LASMO (Computershare Services PLC, PO Box 435, Owen House, 8
     Bankhead Crossway North, Edinburgh EH11 4BR) to send him a letter of
     indemnity for completion in accordance with the instructions given. When
     completed, the letter of indemnity must be lodged with the UK Receiving
     Agent or the US Depositary, in accordance with the instructions given, in
     support of the Form of Acceptance.

<PAGE>   59

        (aa) new Amerada Hess Shares instead of the cash consideration to which
             he would otherwise have been entitled to in consequences of the
             basic terms of the Offer in respect of the number of LASMO Shares
             inserted, or deemed to be inserted, in Box 3A; or

        (bb) cash instead of the new Amerada Hess Shares to which he would

     (iv)  if applicable, an election for the Loan Note Alternative in respect
        of such amount of cash as would otherwise fall to be paid under the

        Match Election), in respect of the number of LASMO Shares inserted, or
        deemed to be inserted, in Box 4 of the Form of Acceptance; and

     (v)   an agreement to execute any further documents and give any further
        assurances which may be required to enable Amerada Hess to obtain the
        full benefit of paragraph 10 of Part B of this Appendix and this
        paragraph 11 and/or to perfect any of the authorities expressed to be
        given hereunder,

     in each case on and subject to the terms and conditions set out or referred
     to in this document and the Form of Acceptance;

(b) unless "NO" is put in Box 8 of the Form of Acceptance that such LASMO
     Shareholder;

        delivery of the Form of Acceptance, directly or indirectly, the mails

        of Canada, Australia or Japan;

     (iii)  has not mailed or otherwise sent the Form of Acceptance into or from

     (iv)  if he is electing for the Loan Note Alternative, is not a US person
        or a distributor and he is not accepting the Offer with a view to the
        offer, sale or delivery, directly or indirectly, of any Loan Notes in or
        into the United States, Australia, Canada or Japan and will not hold or
        acquire any Loan Notes for the account or benefit of any other person
        who he has reason to believe is purchasing for the purpose of that
        offer, sale or delivery; and

     (v)   is not an agent or fiduciary acting on a non-discretionary basis for
        a principal, unless such agent or fiduciary is an authorised employee of
        such principal or such principal has given any instructions with respect
        to the Offer from outside Canada, Australia or Japan;

(c)  that the execution of the Form of Acceptance constitutes, subject to the
     Offer becoming unconditional in all respects in accordance with its terms
     and to an accepting LASMO Shareholder not having validly withdrawn his
     acceptance, the irrevocable appointment of any director of, or any person
     authorised by, Amerada Hess or Goldman Sachs as his agent and/or attorney
     with an irrevocable instruction and authorisation to:

     (i)    complete and execute all or any form(s) of transfer, renunciation or
        other document in relation to the LASMO Shares referred to in paragraph
        11(a)(i) of Part B of this Appendix in favour of Amerada Hess or as
        Amerada Hess or its agents may direct;

     (ii)   deliver any form(s) of transfer, renunciation or other document with
        any certificate or other document of title for registration within six
        months of the Offer becoming unconditional in all respects; and

        necessary or expedient in connection with his acceptance of the Offer

        in paragraph 11(a)(i) of Part B of this Appendix;

(d) that the execution of the Form of Acceptance and its delivery to the UK
     Receiving Agent or the US Depositary constitutes an irrevocable appointment
     of the UK Receiving Agent or the US Depositary

                                      I-23
<PAGE>   60

     as such LASMO Shareholder's attorney and/or agent and an irrevocable
     instruction and authority to such attorney and/or agent:

     (i)    subject to the Offer becoming unconditional in all respects and him
        not having validly withdrawn his acceptance, to transfer to Amerada Hess
        (or to such other person or persons as Amerada Hess or its agent may
        direct) by means of CREST all or any of the Relevant LASMO Shares (but
        not exceeding the number of LASMO Shares in respect of which the Offer
        is accepted or deemed to be accepted); and

     (ii)   if the Offer does not become unconditional in all respects, to give
        instructions to CRESTCo immediately after the Offer lapses (or within
        such longer period as the Panel may permit, not exceeding 14 calendar
        days of the Offer lapsing) to transfer all Relevant LASMO Shares to the
        original available balance of the accepting LASMO Shareholder.

     In this paragraph, "RELEVANT LASMO SHARES" means LASMO Shares in
     uncertificated form in respect of which a transfer or transfers to escrow
     has or have been effected in accordance with the procedures described in
     paragraph 10 of Part B of this Appendix and where the transfer or transfers
     to escrow was or were made in respect of LASMO Shares held under the same
     member account ID and participant ID as the member account ID and
     participant ID relating to the relevant Form of Acceptance (but
     irrespective of whether or not any Form of Acceptance Reference Number, or
     a Form of Acceptance Reference Number corresponding to that appearing on
     the relevant Form of Acceptance, was included in the relevant transfer to
     escrow instruction);

        Loan Notes in respect of his election for the Loan Note Alternative, at
        his risk to the person or agent whose name and address is set out in Box

        address is set out, to the first-named holder at his registered address
        outside Canada, Australia or Japan;

     (iii)  if the LASMO Shares referred to in paragraph 11(a)(i) of Part B of
        this Appendix are in uncertificated form, to Amerada Hess or its agents
        to ensure that an assured payment obligation is created in favour of the

        Shareholder becomes entitled in consequence of the Offer (subject to the
        by-laws of Amerada Hess); and

     (v)   to Amerada Hess, LASMO or their respective agents to record and act
        on any instructions with regard to payments or notices which have been
        entered in the records of LASMO in respect of his holding of LASMO
        Shares;

(f)  that the execution of the Form of Acceptance constitutes his agreement
     that:

        uncertificated form will be despatched in accordance with paragraph
        11(e)(ii) of Part B of this Appendix if the shareholder is a CREST
        member whose registered address is in Canada, Australia or Japan;

     any director of, or person authorised by, Amerada Hess or Goldman Sachs
     within the terms of paragraph 7 of Part B of this Appendix;

(h) that, subject to the Offer becoming unconditional in all respects and him
     not having validly withdrawn his acceptance (or if the Offer will become
     unconditional in all respects or lapse on the outcome of the resolution in
     question or if the Panel gives its consent) and pending registration:

     (i)    Amerada Hess or its agent shall be entitled to direct the exercise
        of any votes and any other rights and privileges (including the right to

        as a member of LASMO (including any Share Certificate(s) or other
        documents of title used as a result of conversion of such Offeree Shares
        into certificated form) to Amerada Hess, care of the UK Receiving Agent;

     (iii)  the execution of the Form of Acceptance by the LASMO Shareholder, in
        respect of the LASMO Shares comprised in such acceptance and in respect
        of which such acceptance has not been validly withdrawn, constitutes an
        authority to any director of, or person authorised by, Amerada Hess or
        Goldman Sachs to sign any document and do such things as may in the
        opinion of that agent and/or attorney seem necessary or desirable in
        connection with the exercise of any votes or other rights or privileges
        attaching to the LASMO Shares held by him (including, without
        limitation, signing any consent to short notice of a general or separate
        class meeting as his agent and/or attorney and on his behalf and
        executing a form of proxy appointing any person nominated by Amerada
        Hess to attend general and separate class meetings of LASMO and
        attending any such meeting and exercising the votes attaching to the
        LASMO Shares referred to in paragraph 11(a)(i) of Part B of this
        Appendix on his behalf, where relevant, such votes to be cast so far as

        of which such acceptance has not been validly withdrawn, constitutes an
        agreement not to exercise any such rights without the consent of Amerada
        Hess and irrevocably undertakes not to appoint a proxy for or to attend
        such general or separate class meetings of LASMO.

     This authority will cease to be valid if the acceptance is validly
     withdrawn in accordance with paragraph 4 of Part B of this Appendix;

(i)  that he will deliver to the UK Receiving Agent or the US Depositary, or
     procure the delivery to the UK Receiving Agent or the US Depositary of, his
     share certificates and/or other document(s) of title in respect of those
     LASMO Shares referred to in paragraph 11(a)(i) of Part B of this Appendix
     that are in certificated form, or an indemnity acceptable to Amerada Hess,
     as soon as possible and in any event within two months of the Offer
     becoming unconditional in all respects;

(j)  that he is the sole legal and beneficial owner of the Offeree Shares in
     respect of which the Offer is accepted or deemed to be accepted or he is
     the legal owner of such Offeree Shares and he has the necessary capacity
     and authority to execute the Form of Acceptance;

(k)  that the Offeree Shares in respect of which the Offer is accepted or deemed
     to be accepted are sold fully paid up and free from all liens, equities,
     charges, encumbrances and other third party rights and/or interests and
     together with all rights now or hereafter attaching thereto, including
     voting rights and the right to receive and retain all dividends, interest

     Appendix that are in uncertificated form in respect of which the Offer has
     been accepted and not validly withdrawn to an escrow balance as soon as
     possible and in any event so that the transfer to escrow settles within two
     months of the Offer becoming unconditional in all respects;

(m) that if for any reason any LASMO Shares in respect of which a transfer to an
     escrow balance has been effected are converted to certificated form, he
     will immediately deliver or ensure the immediate delivery of the share
     certificates or other documents of title in respect of all those LASMO

     entitled under the Offer;

(o) that he will do everything as shall in the opinion of Amerada Hess or its

12. PROCEDURES FOR TENDERING LASMO ADSS

(a) Letter of Transmittal/Notice of Guaranteed Delivery

     If you are a holder of LASMO ADSs evidenced by LASMO ADRs, you will have
     also received a Letter of Transmittal and a Notice of Guaranteed Delivery
     for use in connection with the Offer. This section should be read together
     with the instructions on the Letter of Transmittal. The provisions of this
     paragraph 12 shall be deemed to be incorporated in, and form a part of, the
     relevant Letter of Transmittal. The instructions printed on the relevant
     Letter of Transmittal shall be deemed to form part of the terms of the
     Offer.

(b) Valid tendering

     For a holder of LASMO ADSs evidenced by LASMO ADRs to tender such LASMO
     ADSs validly pursuant to the Offer, either:

     (i)    a properly completed and duly executed Letter of Transmittal,
        together with any required signature guarantees or, in the case of a
        book-entry transfer, an Agent's Message, and any other documents
        required by the Letter of Transmittal, must be received by the US
        Depositary at one of its addresses set out at the back of this document
        and either the LASMO ADRs evidencing such LASMO ADSs must be received by
        the US Depositary at one of such addresses or such LASMO ADRs evidencing
        such LASMO ADSs must be delivered pursuant to the procedure for
        Book-entry transfer set forth below (and a Book-Entry Confirmation
        received by the US Depositary in accordance with such procedures); or

     (ii)   such holder must comply with the Guaranteed Delivery Procedures set
        out in paragraph 12(h) below.

     The Offer in respect of LASMO ADSs evidenced by LASMO ADRs shall be validly
     accepted by (i) delivery of a Letter of Transmittal, the relevant LASMO
     ADRs evidencing LASMO ADSs and other required documents to the US
     Depositary by a holder of LASMO ADSs (without any further action by the US
     Depositary) subject to the terms and Conditions set out in this document
     and the Letter of Transmittal or (ii) completion of the book-entry transfer
     procedures described below. The acceptance of the Offer by a tendering
     holder of LASMO ADSs evidenced by LASMO ADRs pursuant to the procedures
     described above, subject to the withdrawal rights described below, will be
     deemed to constitute a binding agreement between such tendering holder of
     LASMO ADSs and Amerada Hess upon the terms and subject to the conditions of
     the Offer. If a LASMO ADR evidencing a LASMO ADS has been tendered by a
     holder of LASMO ADSs, the LASMO Shares represented by such LASMO ADSs may
     not be tendered independently. A Letter of Transmittal and other required
     documents contained in an envelope postmarked in Canada, Australia or Japan
     or otherwise appearing to Amerada Hess or its agents to have been sent from
     Canada, Australia or Japan may be rejected as invalid.

(c)  Book-entry transfer

     The US Depositary will establish an account at each of the Book-Entry
     Transfer Facilities with respect to interests in LASMO ADSs evidenced by
     LASMO ADRs held in book-entry form for the purposes of the Offer within two
     business days from the date of this document. Any financial institution
     that is a participant in any of the Book-Entry Transfer Facility's systems
     may make book-entry delivery of interests in LASMO ADSs by causing a
     Book-Entry Transfer Facility to transfer such interests in LASMO ADSs into
     the US Depositary's account at such Book-Entry Transfer Facility in
     accordance with that Book-Entry Transfer Facility's procedures for such
     transfer.

     Although delivery of interests in LASMO ADSs evidenced by LASMO ADRs may be
     effected through book-entry transfer into the US Depositary's account at a
     Book-Entry Transfer Facility, either:

     (i)    the Letter of Transmittal, properly completed and duly executed,
        together with any required signature guarantees; or

     (ii)   an Agent's Message,
                                      I-27
<PAGE>   64

     and, in either case, any other required documents, must in any case be
     transmitted to, and received by, the US Depositary at one of its addresses
     set out at the back of this document before LASMO ADSs evidenced by LASMO
     ADRs will be either counted as a valid acceptance, or purchased, or such
     holder must comply with the Guaranteed Delivery Procedures described below.
     Delivery of documents to a Book-Entry Transfer Facility does not constitute
     delivery to the US Depositary.

(d) Method of delivery

     The method of delivery of LASMO ADRs, Letters of Transmittal and all other
     required documents is at the option and risk of the tendering holder of
     LASMO ADSs. LASMO ADSs will be deemed delivered only when the LASMO ADRs
     representing such LASMO ADSs are actually received by the US Depositary
     (including in the case of a book-entry transfer, by Book-Entry
     Confirmation). If delivery is by mail, registered mail with return receipt
     requested, properly insured, is recommended. In all cases, sufficient time
     should be allowed to ensure timely delivery. No acknowledgement of receipt
     of documents will be given by, or on behalf of, Amerada Hess.

(e) Signature guarantees

     No signature guarantee is required on the Letter of Transmittal if:

     (i)    the Letter of Transmittal is signed by the registered holder of the
        LASMO ADSs tendered therewith and such registered holder has not
        completed either the Box entitled "Special Delivery Instructions" or the
        Box entitled "Special Payment Instructions" in the Letter of
        Transmittal; or

     (ii)   such LASMO ADSs are tendered for the account of an Eligible
        Institution.

     In all other cases, all signatures on Letters of Transmittal must be
     guaranteed by an Eligible Institution. See Instructions 1 and 5 to the
     Letter of Transmittal.

(f)  LASMO ADSs and ADRs

     If the LASMO ADSs are registered in the name of a person other than the
     person who signs the Letter of Transmittal, then the tendered LASMO ADRs
     must be endorsed or accompanied by appropriate stock powers, signed exactly
     as the name or names of the registered owner or owners appear on the LASMO
     ADRs, with the signatures on the LASMO ADRs or stock powers guaranteed as
     aforesaid. See Instruction 5 to the Letter of Transmittal.

(g) Partial acceptances (not applicable to book-entry holders of LASMO ADSs)

     If fewer than all of the LASMO ADSs evidenced by any LASMO ADRs delivered
     to the US Depositary are to be tendered, the holder thereof should so
     indicate in the Letter of Transmittal by filling in the number of LASMO
     ADSs which are tendered in the Box entitled "Number of ADSs Tendered". In
     such case, a new LASMO ADR for the remainder of the LASMO ADSs represented
     by the former LASMO ADR will be sent to the person(s) signing such Letter
     of Transmittal (or as such person properly indicates thereon) as promptly
     as practicable following the date the tendered LASMO ADSs are purchased.
     All LASMO ADSs delivered to the US Depositary will be deemed to have been
     tendered unless otherwise indicated. See Instruction 4 to the Letter of
     Transmittal. In the case of partial tenders, LASMO ADSs not tendered will
     not be reissued to a person other than the registered holder.

(h) Guaranteed delivery procedures

     (i)    If a holder of LASMO ADSs evidenced by LASMO ADRs wishes to tender
        LASMO ADSs pursuant to the Offer and the LASMO ADRs evidencing such
        LASMO ADSs are not immediately available or the procedures for
        book-entry transfer cannot be completed on a timely basis, or if time
        will not permit all required documents to reach the US Depositary whilst
        the Offer remains open for acceptance, such holder's tender of LASMO
        ADSs may be effected if all of the following conditions are satisfied
        (the "GUARANTEED DELIVERY PROCEDURES"):

        (aa) such tender is made by or through an Eligible Institution;

                                      I-28

        (bb) a properly completed and duly executed Notice of Guaranteed
             Delivery substantially in the form provided by Amerada Hess is
             received by the US Depositary, as provided below, whilst the Offer
             remains open for acceptance; and

        (cc)  the LASMO ADRs evidencing all tendered LASMO ADSs (or, in the case
             of LASMO ADSs held in book-entry form, timely confirmation of the
             book-entry transfer of such interests in LASMO ADSs into the US
             Depositary's account at a Book-Entry Transfer Facility as described
             above) together with a properly completed and duly executed Letter
             of Transmittal with any required signature guarantees or, in the
             case of a book-entry transfer, an Agent's Message and any other
             documents required by the Letter of Transmittal, are received by
             the US Depositary within three New York Stock Exchange business
             days after the date of execution of such Notice of Guaranteed
             Delivery.

     (ii)   The Notice of Guaranteed Delivery may be delivered by hand,
        transmitted by facsimile transmission or mailed to the US Depositary and
        must include a signature guarantee by an Eligible Institution in the
        form set out in such Notice of Guaranteed Delivery.

     (iii)  Receipt of a Notice of Guaranteed Delivery will not be treated as a
        valid acceptance for the purpose of satisfying the Acceptance Condition.
        To be counted towards satisfaction of this requirement, prior to the end
        of the Initial Offer Period, the LASMO ADRs evidencing LASMO ADSs
        referred to in the Notice of Guaranteed Delivery must be received by the
        US Depositary (or, in the case of interests in LASMO ADSs evidenced by
        LASMO ADRs held in book-entry form, timely confirmation of a book-entry
        transfer of such interests in LASMO ADSs into the US Depositary's
        account at a Book-Entry Transfer Facility pursuant to the procedures set
        out above) together with a duly executed Letter of Transmittal with any
        required signature guarantees (or, in the case of a book-entry transfer
        an Agent's Message) and any other required documents.

(i)  Other requirements

     By executing the Letter of Transmittal as set out above, the tendering
     holder of LASMO ADSs evidenced by LASMO ADRs will agree that, effective
     from and after the date all Conditions are either satisfied, fulfilled or,

        of any votes attaching to any LASMO Shares represented by LASMO ADSs, in
        respect of which the Offer has been accepted or is deemed to have been
        accepted (the "ACCEPTED ADSS") and any other rights and privileges
        attaching to such LASMO Shares, including any right to requisition a
        general meeting of LASMO or any class of its shareholders;

     (ii)   the execution of the Letter of Transmittal (together with any
        signature guarantees) and its delivery to the US Depositary or the

             Accepted ADSs to send any notice, circular, warrant, document or

             form of proxy in respect of such Accepted ADSs appointing any
             person nominated by Amerada Hess to attend general meetings and
             separate class meetings of LASMO and any adjournment thereof and to

             ADSs not to appoint a proxy for or to attend any such general
             meetings or separate class meetings;

             unless such agent or fiduciary is an authorised employee of such
             principal or such principal has given any instructions with respect

             such Accepted ADSs are sold fully paid and free from all liens,
             equitable interests, charges, and encumbrances and together with

        Transmittal the provisions of this Part B shall apply to them jointly
        and to each of them.

13. CURRENCY OF CASH CONSIDERATION

Instead of receiving cash consideration in pounds sterling, LASMO Shareholders
who so wish may elect to receive US dollars on the basis that the cash amount
payable in pounds sterling to which such holder would otherwise be entitled
pursuant to the terms of the Offer will be converted, without charge, from
pounds sterling to US dollars at the exchange rate obtainable by the relevant
payment agent (either the UK Receiving Agent or the US Depositary) on the spot
market in London at approximately noon (London time) on the date the cash
consideration is made available by Amerada Hess to the relevant payment agent
for delivery in respect of the relevant LASMO Shares. A LASMO Shareholder may
receive such amount on the basis set out above only in respect of the whole of
his holding of LASMO Shares in respect of which he accepts the Offer. LASMO
Shareholders may not elect to receive both pounds sterling and US dollars.
Consideration in US dollars may be inappropriate for LASMO Securityholders other
than persons in the US and holders of LASMO ADSs.

Unless they elect to receive pounds sterling, holders of LASMO ADSs will receive
consideration converted into US dollars as described above, as if such holders
of LASMO ADSs had elected to receive dollars.

The actual amount of US dollars received will depend upon the exchange rate
prevailing on the business day on which funds are made available to the relevant
payment agent by Amerada Hess. LASMO Securityholders should be aware that the US
dollar/pounds sterling exchange rate which is prevailing at the date on which an
election is made to receive dollars and on the dates of despatch and receipt of
payment may be different from that prevailing on the business day on which funds
are made available to the relevant payment agent by Amerada Hess. In all cases,
fluctuations in the US dollar/pounds sterling exchange rate are at the risk of
accepting LASMO Securityholders who elect or are treated as having elected to
receive their consideration in US dollars. Neither Amerada Hess nor any of its
advisers or agents shall have any responsibility with respect to the actual
amount of cash consideration payable other than in pounds sterling.

14. SUBSTITUTE ACCEPTANCE FORMS

Holders of LASMO Securities have been sent with this document a Form of
Acceptance and/or a Letter of Transmittal (accompanied by a Notice of Guaranteed
Delivery). All holders of LASMO Shares, including persons in the US who hold
LASMO Shares, have been sent a Form of Acceptance, which they must use to accept
the Offer. All holders of LASMO ADSs have been sent a Letter of Transmittal and
a Notice of Guaranteed Delivery which they must use to tender their LASMO ADSs
in the Offer. Should any holder of LASMO Securities receive an incorrect form
with which to accept the Offer or require any additional forms, that person
should contact the UK Receiving Agent or the US Depositary at the addresses set
out at the back of this document, who will provide the appropriate forms.

                                  APPENDIX II

                         PARTICULARS OF THE LOAN NOTES

The Floating Rate Unsecured Loan Notes 2005 of Amerada Hess will be constituted
by a loan note instrument (the "LOAN NOTE INSTRUMENT") executed as a deed by
Amerada Hess. The issue of the Loan Notes is conditional on the Offer becoming
or being declared unconditional in all respects. The Loan Note Instrument will
contain provisions, inter alia, to the effect set out below.

FORM AND STATUS

1.  The Loan Notes will be issued, credited as fully paid, by Amerada Hess in
     amounts and integral multiples of L1 in nominal amount and will constitute
     unsecured obligations of Amerada Hess. The Loan Note Instrument will not
     contain any restrictions on borrowing, disposals or charging of assets by
     Amerada Hess.

INTEREST

2.  Interest on the outstanding Loan Notes will be payable (subject to any
     requirement to deduct tax therefrom) in arrears on 30 June and 31 December
     in each year or, if such a day is not a business day, on the next following
     business day ("interest payment dates"). The first payment of interest on
     the Loan Notes will be made on 2 July 2001 in respect of the period from
     (but excluding) the date of issue up to (but excluding) 2 July 2001. The
     period from (but excluding) the date of issue up to (but excluding) 2 July
     2001 and the period from (and including) 2 July 2001 or any subsequent
     interest payment date up to (but excluding) the next following interest
     payment date is herein called an "interest period". The last interest
     payment date will be 31 December 2005.

3.  (a)   Interest on the Loan Notes will accrue at the rate per annum which is
        0.5 per cent. below LIBOR, treated for this purpose as the display rate
        per annum of the offered quotation for deposits in sterling for a period
        equal to the required period which appears on Telerate Page 3750 or
        Telerate Page 3740 (as appropriate) at or as soon as practicable after
        11.00 am (London time) on the relevant interest payment date.

     (b)   If the display rate cannot be determined under paragraph (a) above,
        LIBOR for this purpose shall be determined to be the arithmetic mean
        (rounded, if necessary, to the nearest five decimal places with the
        midpoint rounded upwards) of the rates at which the Royal Bank of
        Scotland and Barclays Bank are offering six month sterling deposits or
        its equivalent in the currency which, at the relevant time, is the Loan
        Note currency at or as soon as practicable after 11.00 am (London time)
        on the first day of the relevant interest period or, if such day is not
        a business day, on the preceding business day.

     (c)   Each instalment of interest shall be calculated on the basis of a 365
        day year and the number of days elapsed in the relevant interest period.

REPAYMENT AND REDEMPTION

4.  A holder of Loan Notes (a "NOTEHOLDER") shall be entitled to require Amerada
     Hess to repay the whole (whatever the amount) or any part (being L500 in
     nominal amount or any integral multiple thereof) of the principal amount of
     his holding of Loan Notes at par, together with accrued interest thereon
     (subject to any requirement to deduct tax therefrom) up to but excluding
     the date of repayment, on any interest payment date falling on or after 31
     December 2001, by giving not less than 30 days' prior notice in writing
     (which shall be irrevocable) to Amerada Hess' registrars accompanied by
     certificate(s) for all the Loan Notes to be repaid and a notice of
     redemption (duly completed) in the prescribed form endorsed on the Loan
     Notes to be repaid.

     If at any time after 30 June 2001 the principal amount of all Loan Notes
     outstanding equals 5 per cent. or less in nominal value of the Loan Notes
     issued, Amerada Hess shall have the right on giving the remaining
     Noteholders not less than 30 days' notice in writing expiring on 31
     December 2001 or any subsequent interest payment date, to redeem all (but
     not some only) of the outstanding Loan Notes at par together with accrued
     interest thereon (subject to any requirement to deduct tax therefrom) up to
     but excluding the date of redemption.

                                      II-1
<PAGE>   69

5.  Amerada Hess will have the right to redeem on any interest payment date the
     Loan Notes at par together with accrued interest up to (and including) the
     day immediately before the date of redemption (subject to any requirement
     to deduct tax thereupon) on 30 days' written notice to the Noteholders if
     interest payable under the Loan Notes is reasonably expected by Amerada
     Hess to fall to be treated as non-deductible for US federal income tax
     purposes.

6.  Any Loan Notes not previously so repaid, redeemed or purchased will be
     repaid in full at par on 31 December 2005, together with accrued interest
     thereon (subject to any requirement to deduct tax therefrom) up to and
     excluding that date.

7.  Amerada Hess shall have the right on a redemption by Amerada Hess pursuant
     to paragraph 6 of this Appendix II, by notice in writing to Noteholders
     giving not less than 28 days' notice, to pay each Noteholder (subject to
     certain limitations), in lieu of the sterling amount otherwise payable, an
     amount in US dollars equal to the amount in US dollars that the sterling
     amount equal to the principal amount of the Loan Notes to be redeemed could
     have purchased, on the date being 28 days before 31 December 2005, provided
     that such amount shall be no less or more than (and if it would otherwise
     be, shall be equal to) 99.5 per cent. or 100.5 per cent. of the amount in
     US dollars that the sterling principal amount of the Loan Notes to be
     redeemed could have purchased on 31 December 2005.

8.  Each Noteholder shall have the right on a redemption by Amerada Hess
     pursuant to paragraph 6 of this Appendix II, by notice in writing to
     Amerada Hess giving not less than 28 days notice, to require Amerada Hess
     to pay to such Noteholder (subject to certain limitations), in lieu of the
     sterling amount otherwise payable, an amount in US dollars equal to the
     amount in US dollars that the sterling amount equal to the principal amount
     of the Loan Notes held by such Noteholder to be redeemed could have
     purchased, on the date being 28 days before 31 December 2005, provided that
     such amount shall be no less or more than (and if it would otherwise be,
     shall be equal to) 99.5 per cent. or 100.5 per cent. of the amount in US
     dollars that the sterling principal amount of the Loan Notes to be redeemed
     could have purchased on 31 December 2005.

9.  Any Loan Notes repaid, purchased or redeemed will be cancelled and shall not
     be available for re-issue.

10. Each Noteholder shall be entitled to require all of the Loan Notes held by
     him to be repaid at par together with accrued interest (subject to any
     requirement to deduct any tax therefrom) immediately if:

     (a)   any principal or interest on any of the Loan Notes held by that
        Noteholder shall fail to be paid in full by the time at which Amerada
        Hess is required to make payment in respect of that amount and the
        relevant Noteholder has given Amerada Hess notice of that fact requiring
        Amerada Hess to deliver a cheque or warrant for the relevant amount to
        the registered address of the Noteholder and Amerada Hess has failed to
        make such delivery within fourteen days of receiving such notice; or

     (b)   an order is made or a resolution is passed by the stockholders of
        Amerada Hess for the dissolution of Amerada Hess; or

     (c)   an encumbrancer takes possession of, or a trustee, receiver,
        administrator or similar officer is appointed or an administration order
        is made in respect of, the whole or substantially the whole of the
        undertaking of Amerada Hess and such person has not been paid out or
        discharged within 30 days.

11. Amerada Hess will be entitled at any time to purchase any Loan Notes by
    tender (available to all Noteholders alike), private treaty or otherwise, at
    any price agreed by the Noteholder(s).

MODIFICATION

12. The Noteholders will have power by extraordinary resolution of the
    Noteholders passed in accordance with the provisions of the Loan Note
    Instrument or by resolution in writing signed by holders of not less than 75
    per cent. of the outstanding Loan Notes, inter alia, to sanction any
    modification, abrogation or compromise of or arrangement in respect of their
    rights against Amerada Hess (but subject to the consent of Amerada Hess) and
    to assent to any amendment in respect of their rights against Amerada Hess
    and to assent to any amendment of the provisions of the Loan Note
    Instrument. Amerada Hess may, with the consent of its financial adviser,
    amend the provisions of
                                      II-2
<PAGE>   70

     the Loan Note Instrument, without such sanction or consent, if such
     amendment is of a formal, minor or technical nature or to correct a
     manifest error.

SUBSTITUTION OR EXCHANGE

13. The Loan Notes will contain provisions entitling Amerada Hess, subject to
    certain conditions, to substitute any other member of the Amerada Hess Group
    as the principal debtor under the Loan Note Instrument and the Loan Notes or
    to require all or any of the Noteholders to exchange their Loan Notes for
    loan notes issued on the same terms mutatis mutandis by such other members
    of the Amerada Hess Group. References to Amerada Hess in this summary shall
    be construed accordingly. The obligations of any substituted issuer will be
    fully guaranteed by Amerada Hess.

REGISTRATION, TRANSFER AND MARKETABILITY

14. The Loan Notes will be evidenced by certificates and will be registered and
    transferable in minimum amounts of L500 or multiples thereof or such lower
    amount as Amerada Hess may approve (or the entire holding), provided that
    transfers will not be registered during the 21 days immediately preceding an
    interest payment date or while the register of Noteholders is closed.

15. No application has been made or is intended to be made to any stock exchange
    for the Loan Notes to be listed or otherwise traded.

    offered in compliance with applicable securities laws of Canada or Japan and
    no prospectus in relation to the Loan Notes has been, or will be, lodged

    from, or not subject to, the registration requirements of the Securities
    Act), Australia, Canada or Japan.

Amerada Hess is proceeding with two developments in the Conger and Northwestern
Fields in the Gulf of Mexico. Production is expected to commence from these
fields in the first quarter 2001. These developments are expected to add 55,000
Mcf of natural gas per day and 8,000 barrels of oil per day.

At 31 December 1999, Amerada Hess had an interest in 150 exploration blocks in
the Gulf of Mexico of which it operates 100. Amerada Hess also had 439,092 net
undeveloped acres in the Gulf of Mexico.

United Kingdom

Amerada Hess' activities in the United Kingdom are conducted by its wholly-owned
subsidiary, Amerada Hess Limited. During 1999, 51 per cent. of Amerada Hess'
crude oil and natural gas liquids production and 40 per cent. of its natural gas
production were from United Kingdom operations.

In late 1999, first gas was exported from the Neptune and Mercury Fields in the
southern North Sea, the first phase of the Easington Catchment Area (ECA)
project.

During April 2000, the Bittern Field was brought on stream in the United
Kingdom, produced through the Amerada Hess operated Triton facility.

The table below sets forth Amerada Hess' average daily net production in the
United Kingdom by field and Amerada Hess' interest in each at 30 September 2000:

Norway

Amerada Hess' activities in Norway are conducted through its wholly-owned
Norwegian subsidiary, Amerada Hess Norge A/S. Norwegian operations accounted for
crude oil and natural gas liquids production of 25,856 net barrels per day for
the nine months ended 30 September 2000 and 27,009 net barrels per day in 1999
and 28,322 net barrels per day in 1998. Substantially all of the Norwegian
production is from Amerada Hess' 28.09 per cent. interest in the Valhall Field.
An enhanced-recovery waterflood project for the Valhall Field was approved in
2000 with anticipated completion by the end of 2003.

Denmark

Amerada Hess A/S, Amerada Hess' Danish subsidiary, brought the South Arne Field
on-stream in the third quarter of 1999. Amerada Hess operates this field with a
57.48 per cent. interest. Net production from the South Arne Field for the nine
months ended 30 September 2000 was 25,386 net barrels of crude oil per day and
34,900 Mcf of natural gas per day.

Gabon

Amerada Hess Production Gabon ("AHPG"), Amerada Hess' majority-owned Gabonese
subsidiary, has a 10 per cent. interest in the Rabi Kounga Field in Gabon.
Amerada Hess' share of production averaged 7,404 net barrels of crude oil per
day for the nine months ended 30 September 2000 and 10,226 net barrels of crude
oil per day in 1999 and 14,345 net barrels per day in 1998. The decrease in
Amerada Hess' share of production in 1999 and 2000 was largely due to a reduced
equity interest in AHPG. AHPG has a 40 per cent. interest in the developing
onshore Atora Field. Production from this field is expected to begin in 2001 and
to reach a net level of 4,300 barrels of crude oil per day.

Indonesia

Amerada Hess has a 30 per cent. interest in the Jabung production sharing
contract, which contains the North Geragai and Makmur Fields. Net production
from these fields averaged 3,700 barrels of crude oil per day for the nine
months ended 30 September 2000. The Jabung production sharing contract area
contains additional discoveries for which development plans are either underway
or being considered. In addition, Amerada Hess has interests in other production
sharing contracts in Indonesia on which discoveries have been made.

Thailand

Amerada Hess has a 15 per cent. interest in the Pailin Field offshore Thailand.
The field came onstream in August 1999. Net production from Amerada Hess'
interest averaged 22,500 Mcf of natural gas per day for the nine months ended 30
September 2000.

Azerbaijan

Amerada Hess has a 1.68 per cent. equity interest in the AIOC Consortium in the
Caspian Sea. Net production from its interest is currently averaging
approximately 1,500 barrels of oil per day. On 17 July 2000, Amerada Hess
announced that it had reached agreement, subject to governmental and co-
venturer consent, to acquire a further 2.08 per cent. interest in the AIOC
Consortium. Amerada Hess additionally has interests in two onshore fields with
initial net production of approximately 1,000 barrels per day of crude oil.

Algeria

In April 2000, Amerada Hess acquired the Gassi El Agreb redevelopment project
from Sonatrach, the Algerian State oil company. The redevelopment project is
designed to increase production from the fields from the current gross level of
27,000 barrels per day of crude oil to 45,000 barrels per day late in 2003.
Sonatrach will retain 51 per cent. of gross production volumes, with the
remaining 49 per cent. being available for cost recovery by both Sonatrach and
Amerada Hess. After cost recovery, the remaining production will be divided
between Sonatrach and Amerada Hess dependant on the cumulative rate of return on
capital invested.

Brazil

Amerada Hess has 32 per cent. net equity interests and operatorship of Blocks
BC-8 in the Southern Campos Basin and BS-2 in the Northern Santos Basin offshore
Brazil. Amerada Hess commenced exploration drilling on these blocks in 2000.
Amerada Hess also acquired a 45 per cent. interest in an exploration licence on
Block BM S-3 in the Santos Basin and a 16 per cent. interest in an exploration
licence on Block BCe-2 in the Potiguar Basin. In June 2000, in the second
Brazilian licensing round, Amerada Hess was awarded two licences for exploration
blocks in the Sergipe-Alagoas Basin, BM-Seal-5 (Amerada Hess 85 per cent.) and
BM-Seal-4 (Amerada Hess 40 per cent.).

REFINING AND MARKETING

Refining and marketing has become a smaller, more profitable portion of the
Amerada Hess portfolio than it was in the past.

Refining

Amerada Hess owns a 50 per cent. interest in the HOVENSA refining joint venture
in the United States Virgin Islands. In addition, it owns and operates a
refining facility in Port Reading, New Jersey.

HOVENSA

In 1999, total refinery crude runs averaged 418,000 barrels per day compared
with 421,000 barrels per day in 1998. The refinery joint venture with a
subsidiary of Petroleos de Venezuela S.A. was formed on 30 October 1998.
Petroleos de Venezuela supplies 155,000 barrels per day of Venezuelan Mesa crude
oil to HOVENSA under a long-term crude oil supply contract. The remaining crude
oil is purchased mainly under contracts of one year or less from third parties
and through spot purchases on the open market. After sales of refined products
by HOVENSA to third parties, Amerada Hess must purchase 50 per cent. of
HOVENSA's remaining production at market prices.

In February 2000, HOVENSA reached agreement on a $600 million bank financing for
the construction of a 58,000 barrel per day delayed coking unit and related
facilities at its refinery. HOVENSA has begun building the coker, which is
anticipated to be completed in 2002. HOVENSA has a long-term supply contract
with Petroleos de Venezuela to purchase 115,000 barrels per day of Venezuelan
heavy Merey crude oil beginning when the coker is completed.

Port Reading Facility

Amerada Hess owns and operates a fluid catalytic cracking facility in Port
Reading, New Jersey. This facility processes vacuum gas oil and residual fuel
oil. It currently operates at a rate of approximately 60,000 barrels per day and
produces substantially all gasoline and heating oil.

Marketing

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 915 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 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.

Refined product sales averaged 356,000 barrels per day in the first nine months
of 2000 and 344,000 barrels per day in 1999 and 482,000 barrels per day in 1998.
Of total refined products sold in 1999, approximately 70 per cent. was obtained
from HOVENSA and Port Reading. Amerada Hess purchased the balance from others
under short-term supply contracts and by spot purchases from various sources.

COMPETITION AND MARKET CONDITIONS

The petroleum industry is highly competitive. Amerada Hess encounters
competition from numerous companies in each of its activities, particularly in
acquiring rights to explore for crude oil and natural gas and in the purchasing
and marketing of refined products. Many competitors are larger and have
substantially greater resources than Amerada Hess. Amerada Hess is also in
competition with producers and marketers of other forms of energy.

The petroleum business involves large-scale capital expenditure and risk-taking.
In the search for new oil and gas reserves, long lead times are often required
from successful exploration to subsequent production. Operations in the
petroleum industry depend on a depleting natural resource. The number of areas
where it can be expected that hydrocarbons will be discovered in commercial
quantities is constantly diminishing and exploration risks are high. Areas where
hydrocarbons may be found are often in remote locations or offshore where
exploration and development activities are capital intensive and operating costs
are high.

The major foreign oil producing countries, including members of the Organization
of Petroleum Exporting Countries ("OPEC"), exert considerable influence over the
supply and price of crude oil and refined petroleum products. Their ability or
inability to agree on a common policy on rates of production and other matters
has a significant impact on oil markets and Amerada Hess. The derivatives
markets are also important in influencing the prices of crude oil, natural gas
and refined products. Amerada Hess cannot predict the extent to which future
market conditions may be affected by foreign oil producing countries, the
derivatives markets or other external influences.

OTHER ITEMS

Amerada Hess' operations may be affected by federal, state, local, territorial
and foreign laws and regulations relating to tax increases and retroactive tax
claims, expropriation of property, cancellation of contract rights, and changes
in import regulations, as well as other political developments. Amerada Hess has
been affected by certain of these events in various countries in which it
operates. Amerada Hess markets motor fuels through lessee-dealers and
wholesalers in certain states where legislation prohibits producers or refiners
of crude oil from directly engaging in retail marketing of motor fuels. Similar
legislation has been periodically proposed in the U.S. Congress and in various
other states. Amerada Hess, at this time, cannot predict the effect of any of
the foregoing on its future operations.

Compliance with various environmental and pollution control regulations imposed
by federal, state and local governments is not expected to have a materially
adverse effect on Amerada Hess' earnings and competitive position within the
industry. Capital expenditures for facilities, primarily to comply with federal,
state and local environmental standards, were $2 million in 1999 and Amerada
Hess anticipates comparable capital expenditures in 2000. In addition, Amerada
Hess expended $8 million in 1999 for environmental remediation, with a
comparable amount anticipated for 2000.

The number of persons employed by Amerada Hess averaged 8,485 in 1999 and 9,777
in 1998.

AMERADA HESS CORPORATION AND CONSOLIDATED SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL INFORMATION

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business: Amerada Hess Corporation and subsidiaries (the
"Corporation") engage in the exploration for and the production, purchase,
transportation and sale of crude oil and natural gas. These activities are
conducted primarily in the United States, United Kingdom, Norway, Denmark and
Gabon. The Corporation also has oil and gas activities in Azerbaijan, Brazil,
Indonesia, Thailand and other countries. In addition, the Corporation
manufactures, purchases, transports and markets refined petroleum and other
energy products. The Corporation owns 50% of a refinery joint venture in the
United States Virgin Islands. An additional refining facility, terminals and
retail gasoline stations are located on the East Coast of the United States.

In preparing financial statements, management makes estimates and assumptions
that affect the reported amounts of assets and liabilities in the balance sheet
and revenues and expenses in the income statement. Actual results could differ
from those estimates. Among the estimates made by management are: oil and gas
reserves, asset valuations and depreciable lives, pension liabilities,
environmental obligations, dismantlement costs and income taxes.

Principles of Consolidation: The consolidated financial information includes the
accounts of Amerada Hess Corporation and subsidiaries. The Corporation's
interests in oil and gas exploration and production ventures are proportionately
consolidated.

Investments in affiliated companies, 20% to 50% owned, including HOVENSA L.L.C.,
the Corporation's refining joint venture, are stated at cost of acquisition plus
the Corporation's equity in undistributed net income since acquisition, except
as stated below. The change in the equity in net income of these companies is
included in non-operating income in the income statement. The Corporation
consolidates a trading partnership in which it owns a 50% voting interest and
over which it exercises control.

Intercompany transactions and accounts are eliminated in consolidation.

Certain amounts in prior years' financial statements have been reclassified to
conform with current year presentation.

Revenue Recognition: The Corporation recognizes revenues from the sale of crude
oil, natural gas, petroleum products and other merchandise when title passes to
the customer.

The Corporation recognizes revenues from the production of natural gas
properties in which it has an interest based on sales to customers. Differences
between natural gas volumes sold and the Corporation's share of natural gas
production are not material.

Cash and Cash Equivalents: Cash equivalents consist of highly liquid
investments, which are readily convertible into cash and have maturities of
three months or less.

Inventories: Crude oil and refined product inventories are valued at the lower
of cost or market, except for inventories held for trading purposes which are
marked to market. For inventories valued at cost, the Corporation uses
principally the last-in, first-out inventory method.

Inventories of materials and supplies are valued at or below cost.

Exploration and Development Costs: Oil and gas exploration and production
activities are accounted for using the successful efforts method. Costs of
acquiring undeveloped oil and gas leasehold acreage, including lease bonuses,
brokers' fees and other related costs, are capitalized.

Annual lease rentals and exploration expenses, including geological and
geophysical expenses and exploratory dry hole costs, are charged against income
as incurred.

Costs of drilling and equipping productive wells, including development dry
holes, and related production facilities are capitalized.

The Corporation does not carry the capitalized costs of exploratory wells as an
asset for more than one year, unless oil and gas reserves are found and
classified as proved, or additional exploration is underway or planned. If
exploratory wells do not meet these conditions, the costs are charged to
expense.

                                     III-13
<PAGE>   84

Depreciation, Depletion and Amortization: Depreciation, depletion and
amortization of oil and gas production equipment, properties and wells are
determined on the unit-of-production method based on estimated recoverable oil
and gas reserves. Depreciation of all other plant and equipment is determined on
the straight-line method based on estimated useful lives.

The estimated costs of dismantlement, restoration and abandonment, less
estimated salvage values, of offshore oil and gas production platforms and
certain other facilities are taken into account in determining depreciation.

Retirement of Property, Plant and Equipment: Costs of property, plant and
equipment retired or otherwise disposed of, less accumulated reserves, are
reflected in net income.

Impairment of Long-Lived Assets: The Corporation reviews long-lived assets,
including oil and gas properties, for impairment whenever events or changes in
circumstances indicate that the carrying amounts may not be recovered. If the
carrying amounts are not expected to be recovered by undiscounted future cash
flows, the assets are impaired and an impairment loss is recorded. The amount of
impairment is based on the estimated fair value of the assets determined by
discounting anticipated future net cash flows. The net present value of future
cash flows is based on the Corporation's estimates, including future oil and gas
prices applied to projected production profiles, discounted at a rate
commensurate with the risks involved. Oil and gas prices used for determining
asset impairments may differ from those used at year-end in the standardized
measure of discounted future net cash flows.

Provisions for impairment of undeveloped oil and gas leases are based on
periodic evaluations and other factors.

Maintenance and Repairs: The estimated costs of major maintenance, including
turnarounds at the Port Reading refining facility, are accrued. Other
expenditures for maintenance and repairs are charged against income as incurred.
Renewals and improvements are treated as additions to property, plant and
equipment, and items replaced are treated as retirements.

Environmental Expenditures: The Corporation capitalizes environmental
expenditures that increase the life or efficiency of property or that reduce or
prevent environmental contamination. The Corporation accrues for environmental
expenses resulting from existing conditions related to past operations when the
future costs are probable and reasonably estimable.

Employee Stock Options and Nonvested Common Stock Awards: The Corporation uses
the intrinsic value method to account for employee stock options. Because the
exercise prices of employee stock options equal or exceed the market price of
the stock on the date of grant, the Corporation does not recognize compensation
expense. The Corporation records compensation expense for nonvested common stock
awards ratably over the vesting period.

Foreign Currency Translation: The U.S. dollar is the functional currency
(primary currency in which business is conducted) for most foreign operations.
For these operations, adjustments resulting from translating foreign currency
assets and liabilities into U.S. dollars are recorded in income. For operations
that use the local currency as the functional currency, adjustments resulting
from translating foreign functional currency assets and liabilities into U.S.
dollars are recorded in a separate component of stockholders' equity entitled
"Accumulated other comprehensive income." Gains or losses resulting from
transactions in other than the functional currency are reflected in net income.

Hedging: The Corporation uses futures, forwards, options and swaps to hedge the
effects of fluctuations in the prices of crude oil, natural gas and refined
products and changes in interest rates and foreign currency values. These
transactions meet the requirements for hedge accounting, including designation
and correlation. The resulting gains or losses, measured by quoted market
prices, termination values or other methods, are accounted for as part of the
transactions being hedged, except that losses not expected to be recovered upon
the completion of hedged transactions are expensed. On the balance sheet,
deferred gains and losses are included in current assets and liabilities.

Trading: Commodity trading activities are marked to market, with gains and
losses recorded in operating revenue.

NOTE 2 -- SPECIAL ITEMS

1999: The Corporation recorded a gain of $274,100,000 ($176,000,000 after income
taxes) from the sale of its Gulf Coast and Southeast pipeline terminals, natural
gas properties in California and certain

                                     III-14
<PAGE>   85

retail sites. Exploration and production results include special income tax
benefits of $54,600,000, reflecting actions taken in 1999 to realize the United
States tax impact of certain prior year exploration activities and capital
losses.

Exploration and production earnings also include an impairment of $58,700,000
($38,200,000 after income taxes) for the Corporation's interest in the Trans
Alaska Pipeline System. The Corporation currently has no crude oil production in
Alaska and there has been a significant reduction in crude oil volumes shipped
through the Corporation's share of the pipeline. Refining and marketing results
include an asset impairment of $34,000,000 (with no income tax benefit) for the
Corporation's crude oil storage terminal in St. Lucia, due to the nonrenewal of
a major third party storage contract. The terminal had been partially impaired
in 1998 as a result of the reduced crude oil storage requirements of the HOVENSA
joint venture. The Corporation also accrued $35,300,000 ($27,300,000 after
income taxes) for a further decline in the value of a drilling service
fixed-price contract due to lower market rates. At December 31, 1999, the
Corporation's reserve for drilling service contracts was $54,600,000, including
amounts provided in 1998. During the year, $70,700,000 of contract payments were
charged against the reserve.

Gains on asset sales are included on a separate line in non-operating income in
the income statement. The impairment of carrying values of the Alaska pipeline
and the crude oil storage terminal and the loss on the drilling service contract
are reflected in a separate impairment line in the income statement.

1998: The Corporation recorded a loss of $106,000,000 in connection with the
sale of the 50% interest in the fixed assets of its Virgin Islands refinery. The
Corporation also recorded an additional charge of $44,000,000 for the reduction
in carrying value of its crude oil storage terminal in St. Lucia that is being
used less as a result of the joint venture. No income tax benefit was recorded
on either charge. Exploration and production results included a charge of
$90,000,000 ($77,000,000 after income taxes) for the reduction in market value
of drilling service fixed-price contracts due to the decline in worldwide crude
oil prices. A charge of $54,000,000 ($35,000,000 after income taxes) was also
recorded for the impairment of capitalized costs related to a North Sea oil
discovery that was uneconomic. The Corporation expensed $29,000,000 for its
share of asset impairment of an equity affiliate and $13,000,000 for the
reduction in carrying value of developed and undeveloped properties in the
United States and United Kingdom. In addition, the Corporation recorded gains of
$80,300,000 ($56,200,000 after income taxes) on the sale of oil and gas assets
in the United States and Norway.

In 1998, the Corporation recorded pre-tax charges of $23,000,000 ($15,000,000
after income taxes) for severance costs. The severance costs covered
approximately 400 exploration and production employees (of which approximately
200 had been terminated at December 31, 1998). Approximately $2,000,000 of
severance was paid in 1998 and the remainder was paid in 1999. The Corporation
also recorded $8,000,000 of exit costs (accrued office lease costs).
Approximately $3,400,000 of this reserve was used in 1999 and the remainder was
reversed to income as a result of current plans for use of the office space.

1997: The Corporation recorded a charge of $80,600,000 ($55,000,000 after income
taxes) for impairment of long-lived assets and a long-term operating lease, as a
result of reserve revisions on two oil fields in the United Kingdom North Sea.
The Corporation also recorded income of $38,200,000 from a refund of United
Kingdom Petroleum Revenue Taxes. In 1997, the Corporation sold its interest in a
United States natural gas field resulting in an after-tax gain of $10,700,000.

NOTE 3 -- ACCOUNTING CHANGES

Effective January 1, 1999, the Corporation adopted the last-in, first-out (LIFO)
inventory method for valuing its refining and marketing inventories. The
Corporation believes that the LIFO method more closely matches current costs and
revenues and will improve comparability with other oil companies. The change to
LIFO decreased net income by $97,051,000 for the year ended December 31, 1999
($1.08 per share basic and diluted). There is no cumulative effect adjustment as
of the beginning of the year for this type of accounting change.

On January 1, 1998, the Corporation began capitalizing the cost of internal use
software in accordance with AICPA Statement of Position 98-1. This accounting
change increased net income for 1998 by $13,867,000 ($.15 per share).

In June 1998, the Financial Accounting Standards Board issued FAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. The Corporation
must adopt FAS No. 133 by January 1, 2001. This
                                     III-15
<PAGE>   86

statement requires that the Corporation recognize all derivatives on the balance
sheet at fair value. For derivatives that are not hedges, the change in fair
value must be recognized in income. For derivatives that hedge changes in the
fair value of assets, liabilities or firm commitments, the gains or losses are
recognized in earnings together with the offsetting losses or gains on the
hedged items. For derivatives that hedge cash flows of forecasted transactions,
the gains or losses are recognized in other comprehensive income until the
hedged items are recognized in income.

The Corporation has not yet determined what the effect of FAS No. 133 will be on
its income and financial position.

NOTE 5 -- REFINING JOINT VENTURE

In 1998, the Corporation formed HOVENSA L.L.C. (HOVENSA), a joint venture with
Petroleos de Venezuela, S.A. (PDVSA). The Corporation's Virgin Islands
subsidiary and PDVSA, V.I., Inc. (PDVSA V.I.), a wholly-owned subsidiary of
PDVSA, contributed their 50% interests in the fixed assets of the Virgin Islands
refinery, previously wholly-owned by the Corporation, to HOVENSA. HOVENSA is 50%
owned by a subsidiary of the Corporation and 50% owned by PDVSA V.I. and
operates the refinery. The Corporation purchased refined products from HOVENSA
at a cost of approximately $1,196,000,000 during 1999 and $151,000,000 during
the two months ended December 31, 1998. The Corporation sold crude oil to
HOVENSA at a cost of approximately $81,000,000 during 1999 and $7,000,000 during
the two months ended December 31, 1998.

The Corporation's investment in the joint venture is accounted for using the
equity method. Summarized financial information for HOVENSA as of December 31,
1999 and for the year then ended and as of December 31, 1998 and for the two

As part of the formation of the joint venture, PDVSA, V.I. purchased a 50%
interest in the fixed assets of the Corporation's Virgin Islands refinery for
$62,500,000 in cash and a 10-year note from PDVSA V.I. for $562,500,000 bearing
interest at 8.46% per annum and requiring principal payments over its term. At
December 31, 1999, the principal balance of the note was $538,500,000. In
addition, there was a $125,000,000, 10-year, contingent note, also bearing
interest at 8.46% per annum. The contingent note was not valued for accounting
purposes. PDVSA V.I.'s payment obligations under both notes are guaranteed by
PDVSA and secured by a pledge of PDVSA V.I.'s interest in the joint venture.

In February 2000, HOVENSA reached agreement on a $600,000,000 bank financing for
the construction of a 58,000 barrel per day delayed coking unit and related
facilities at its refinery and for general working capital requirements. In
connection with the financing, the Corporation and PDVSA V.I. agreed to amend
the note received by the Corporation at the formation of the joint venture.

$300,000,000 bears interest at 7 3/8% and is due in 2009 and the remainder bears
interest at 7 7/8% and is due in 2029. After discount and the effect of interest
rate conversion agreements, the effective borrowing rates are 6.48% and 7.97%,
respectively.

The Corporation has a $2,000,000,000 Global Revolving Credit Facility (the
"Facility"), of which $120,000,000 is outstanding at December 31, 1999.

("LIBOR") based on the Corporation's capitalisation ratio. The borrowing rate at
December 31, 1999 is .20% above LIBOR. Facility fees of .125% per annum are
payable on the amount of the credit line.

In 1998, the Corporation entered into the sale and leaseback of its interests in
the production platforms and related facilities of two Gulf of Mexico producing
properties. These transactions were accounted for as financings. At December 31,
1999, the outstanding obligations amount to $182,588,000, maturing through 2014.

The Corporation sold a portion of its subsequent year crude oil production in
1998 and used the proceeds to repay revolving credit debt. Accordingly, at
December 31, 1998, $249,325,000 is included in deferred revenue on the balance
sheet. There was no comparable transaction in 1999.

At December 31, 1999, the Corporation has interest rate conversion agreements,

Exercise prices for employee stock options at December 31, 1999 ranged from
$49.00 to $65.94 per share. The weighted-average remaining contractual life of
employee stock options is 8.2 years.

The Corporation uses the Black-Scholes model to estimate the fair value of
employee stock options for pro forma disclosure of the effects on net income and
earnings per share. The Corporation used the following weighted-average
assumptions in the Black-Scholes model for 1999, 1998 and 1997, respectively:
risk-free interest rates of 5.9%, 5.6% and 5.9%; expected stock price volatility
of .207, .218 and .220; a dividend yield of 1.1%; and an expected life of seven
years. The Corporation's net income would have been reduced by approximately
$6,000,000 in 1999, $19,100,000 in 1998 and $7,600,000 in 1997 ($.07 per share
in 1999, $.21 per share in 1998 and $.08 per share in 1997, diluted) if option
expense were recorded using the fair value method.

The weighted-average fair values of options granted for which the exercise price
equalled the market price on the date of grant were $18.45 in 1999, $17.50 in
1998 and $18.69 in 1997.

Total compensation expense for nonvested common stock was $9,831,000 in 1999,
$15,975,000 in 1998 and $11,553,000 in 1997. Awards of nonvested common stock
were as follows:

The Corporation also has a nonqualified supplemental pension plan covering
certain employees. The supplemental pension plan provides for incremental
pension payments from the Corporation's funds so that total pension payments
equal amounts that would have been payable from the Corporation's principal
pension plan were it not for limitations imposed by income tax regulations. The
benefit obligation related to this unfunded plan totalled $38,358,000 at
December 31, 1999 and $41,802,000 at December 31, 1998. Pension expense for the
plan was $6,743,000 in 1999, $6,271,000 in 1998 and

$5,098,000 in 1997. The Corporation has accrued $29,310,000 for this plan at
December 31, 1999 and $25,205,000 at December 31, 1998. The trust established to
fund the supplemental plan held assets valued at $13,586,000 at December 31,

The Corporation has not recorded deferred income taxes applicable to
undistributed earnings of foreign subsidiaries that are indefinitely reinvested
in foreign operations. Undistributed earnings amounted to approximately $950
million at December 31, 1999, excluding amounts which, if remitted, generally
would not result in any additional U.S. income taxes because of available
foreign tax credits. If the earnings of such foreign subsidiaries were not
indefinitely reinvested, a deferred tax liability of approximately $120 million
would have been required.

For income tax reporting at December 31, 1999, the Corporation has general
business credit carryforwards of approximately $30 million, principally expiring
in 2000 and 2001. In addition, the Corporation has alternative minimum tax
credit carryforwards of approximately $110 million, which can be carried forward
indefinitely. At December 31, 1999, a net operating loss carryforward of
approximately $1 billion is also available to offset income of the HOVENSA joint
venture partners. Net operating loss carryforwards relating to several foreign
exploration and production areas amount to approximately $190 million at
December 31, 1999.

Income taxes paid (net of refunds) in 1999, 1998 and 1997 amounted to
$141,465,000, $140,470,000 and $259,767,000, respectively.

NOTE 14 -- FINANCIAL INSTRUMENTS, HEDGING AND TRADING ACTIVITIES

The Corporation uses futures, forwards, options and swaps, individually or in
combination, to reduce the effects of fluctuations in crude oil, natural gas and
refined product prices and in fixed-price sales contracts. In addition, the
Corporation uses interest-rate conversion agreements to adjust the interest
rates on a portion of its long-term, fixed-rate debt. Foreign currency contracts
are used to protect the Corporation from fluctuations in exchange rates.

Commodity Hedging: At December 31, 1999, the Corporation's hedging activities
included commodity and financial contracts, maturing mainly in 2000, covering
29,700,000 barrels of crude oil and 1,400,000 barrels of refined products
(3,000,000 net barrels of crude oil and refined products in 1998). The
Corporation also hedged 4,500,000 net Mcf of natural gas in 1998.

The Corporation produced 85,000,000 barrels of crude oil and natural gas liquids
and 235,000,000 Mcf of natural gas in 1999, and had approximately 14,000,000
barrels of crude oil and refined products in its refining and marketing
inventories at December 31, 1999. Since the contracts described above are
designated as hedges and correlate to price movements of crude oil, natural gas
and refined products, any gains or losses resulting from market changes will be
offset by losses or gains on the Corporation's hedged inventory or production.
Net deferred losses from the Corporation's hedging activities were $61,200,000
at December 31, 1999, including $47,600,000 of unrealized losses ($5,000,000 of
gains at December 31, 1998, including $2,000,000 of unrealised gains).

Financial Instruments: At December 31, 1999, the Corporation has $400,000,000 in
interest-rate conversion agreements outstanding ($400,000,000 at December
31,1998). The Corporation also has $865,000,000 of notional value foreign
currency forward and purchased option contracts maturing generally in 2000
($97,000,000 at December 31, 1998) and $145,300,000 in letters of credit
outstanding ($137,900,000 at December 31, 1998). Notional amounts do not
quantify risk or represent assets or liabilities of the Corporation, but are
used in the calculation of cash settlements under the contracts.

Fair Value Disclosure: The carrying amounts of cash and cash equivalents,
short-term debt and long-term, variable-rate debt approximate fair value. The
Corporation estimates the fair value of its long-term, fixed-rate note
receivable and debt generally using discounted cash flow analysis based on
current interest rates for instruments with similar maturities. Interest-rate
conversion agreements and foreign currency exchange contracts are valued based
on current termination values or quoted market prices of comparable contracts.
The Corporation's valuation of commodity contracts considers quoted market
prices, time value, volatility of the underlying commodities and other factors.

The carrying amounts of the Corporation's financial instruments and commodity
contracts, including those used in the Corporation's hedging and trading
activities, generally approximate their fair values at December 31,1999, except
as follows:

Market and Credit Risks: The Corporation's financial instruments expose it to
market and credit risks and may at times be concentrated with certain
counterparties or groups of counterparties. The credit worthiness of
counterparties is subject to continuing review and full performance is
anticipated.

partnership, trades energy commodities, including futures, forwards, options and
swaps, based on expectations of future market conditions. The Corporation's
results from trading activities, including its share of the earnings of the
trading partnership which has been profitable in 1999, 1998 and 1997, amounted

In February 2000, HOVENSA reached agreement on a $600 bank financing for the
construction of a 58 thousand barrel per day delayed coking unit and related
facilities at its refinery and for general working capital requirements. In
connection with this financing, the Corporation and PDVSA V.I. agreed to amend
the note received by the Corporation at the formation of the joint venture.
PDVSA V.I. deferred principal payments on the note until after completion of
coker construction but not later than February 14, 2003. The interest rate on
the note increased to 9.46%. In October 2000, PDVSA V.I. exercised its option to
repay principal in accordance with the original amortization schedule and
reduced the interest rate to the original rate of 8.46%.

NOTE 7 -- The Corporation uses futures, forwards, options and swaps,
individually or in combination, to reduce the effects of fluctuations in crude
oil, natural gas and refined product prices. These contracts correlate to
movements in the value of inventory and the prices of crude oil and natural gas,
and as hedges, any resulting gains or losses are recorded as part of the hedged
transaction. After-tax earnings from exploration and production activities were
reduced by approximately $50 and $100 for the third quarter and nine months of
2000, due to hedging activities. At September 30, 2000, after-tax deferred
losses on the Corporation's petroleum hedging contracts expiring through 2001
were approximately $190, including $145 of unrealized losses.

1.  BUSINESS DESCRIPTION

LASMO, headquartered in London, is a substantial oil and gas exploration
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 31 December
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 L463 million
(1999: L216 million) and profit before exceptional items and taxation of L187
million (1999: L35 million). Net assets as at 30 June 2000 were L1,467 million.
For the full year ended 31 December 1999, LASMO had sales of L594 million (1998:
L484 million) and profit before exceptional items and taxation of L170 million
(1998: L1 million).

During the six months to 30 June 2000, LASMO's exploration programme resulted in
three discoveries in Indonesia and two in Venezuela. Production in both
Liverpool Bay and Venezuela increased significantly. Approvals were received and
contracts awarded in North Africa and milestones reached in bringing gas to
market in Pakistan.

2.  FINANCIAL INFORMATION FOR LASMO

The financial information relating to LASMO set out below has been extracted
without material adjustment from the UK audited accounts of LASMO for the three
years ended 31 December 1999 except for the restatement of the 1997 and 1998
financial statements to comply with Financial Reporting Standard No.12
"Provisions, Contingent Liabilities and Contingent Assets" ("FRS 12").

FRS 12 requires the full discounted cost of decommissioning to be recognised as
an asset and liability when the obligation to rectify environmental damage
arises. Previously the provision for decommissioning costs was built up over the
life of field. The unwinding of the discount is included in the profit and loss
account as a financial item and is added to the net interest charge.

The implementation of FRS 12 has had the effect of increasing the net book value
of tangible fixed assets by L16 million, reducing the decommissioning provision
by L8 million and increasing reserves by L24 million as at December 31, 1998.
There has been no material effect on reported earnings.

The financial information for LASMO does not constitute statutory accounts
within the meaning of Section 240 of the Companies Act. Ernst & Young,
Registered Auditors, of Becket House, 1 Lambeth Palace Road, London SE1 7EU,
England, are auditors of LASMO and have made audit reports under Section 235 of
the Companies Act on the consolidated statutory accounts for the three years
ended 31 December 1999, which have been delivered to the Registrar of Companies
in accordance with Section 242 of the Companies Act.

STATEMENT OF ACCOUNTING POLICIES

BASIS OF PREPARATION

Principal accounting policies are set out below. These policies are consistent
with those adopted in previous years, amended for the effects of adopting FRS
12.

The financial information has been prepared under the historical cost
convention, using the "successful efforts" method of accounting, and in
accordance with applicable accounting standards as defined by the Companies Act.

The preparation of financial statements requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

BASIS OF CONSOLIDATION

The consolidated financial information includes the financial statements of
LASMO plc and all its subsidiary undertakings for the year ended 31 December
1999. All these undertakings are companies, and hereafter are identified as
such, except for a 50 per cent. interest in a general partnership (Unimar
Company) which has been accounted for using the gross equity method. No profit
and loss account is presented for the company as permitted by Section 230 of the
Companies Act.

The Group conducts a substantial proportion of its oil and gas exploration and
development activity through unincorporated joint ventures. The share of these
joint ventures' results and net assets attributable to LASMO are reflected in
the Group's consolidated financial information except where LASMO acts as
operator on behalf of a consortium of partners, in which case, amounts due
to/from third parties are reported gross as are amounts due to/from the
non-operating partners.

Subsidiaries acquired or sold during the year are included from the effective
date of acquisition or to the effective date of disposal.

TURNOVER

Turnover comprises amounts receivable for invoiced sales, exclusive of value
added taxation and similar levies. The Group's entitlement to proceeds from
Indonesian LNG sales is included in turnover after adjustment to add back the
Group's share of transportation and liquefaction costs and debt service which is
deducted on an incurred basis on loans raised by the owner to finance the
construction and expansion costs of the Bontang LNG plant which is operated on a
break even basis. Cost of sales is also adjusted to reflect these deductions,
except that only equal annual charges for debt service are deducted so as to
spread the financing costs over the remaining lives of the respective sales
contracts

                                      IV-4
<PAGE>   108

rather than the uneven repayment schedules established for the loans. The
resultant deferred debt service charges are included in debtors.

Turnover includes a service fee based on production from the Dacion Area in
Venezuela and calculated in accordance with the terms of the operating
agreement. A set fee of $2.50 per barrel is receivable for baseline production
and a fee determined by reference to a basket of crude oil products is
receivable for incremental production. Baseline production for 1999 was 10,700
boepd, and declines by 8% per annum.

PETROLEUM REVENUE TAX (PRT)

PRT is treated as a production cost and has been charged or credited before
arriving at operating profit. Provision is made for current PRT on revenue from
petroleum sales less all allowable deductions for the period.

DEFERRED TAXATION

Deferred taxation is provided in respect of liabilities relating to timing
differences between profits as computed for taxation purposes and profits as
stated in the financial information, except to the extent that the liability is
not expected to crystallise in the foreseeable future. The provision arises
principally from the different accounting and tax treatments for amortising oil
and gas expenditure.

FOREIGN CURRENCIES

Transactions in foreign currencies are recorded at exchange rates ruling at the
date of each transaction or a contract rate where applicable.

Assets and liabilities of overseas subsidiary and associated companies and of UK
companies with non-sterling functional currencies are translated into sterling
at rates current at the balance sheet date. Trading results and cash flows of
such companies are translated into sterling at average rates. Unrealised gains
or losses on revaluation of net assets of overseas subsidiary and associated
companies and on revaluation of Group borrowings arranged to finance or hedge
those net assets are taken directly to retained earnings. All other gains and
losses on translation are dealt with in the profit and loss account.

DERIVATIVE FINANCIAL INSTRUMENTS

The Group may, from time to time, use derivative financial instruments
(derivatives) to limit its exposure to fluctuations in foreign currency exchange
rates and interest rates, and to manage some of its exposure to changes in oil
prices.

Gains or losses arising on oil price derivatives are recognised in revenues from
oil production when hedged volumes are sold.

As part of exchange risk management, foreign currency swap agreements and
forward contracts are used to hedge movements in underlying currencies of
certain borrowings. Gains and losses on these derivatives are deferred and
recognised on maturity of the underlying debt together with the matching
exchange loss or gain on the debt.

Foreign currency forward contracts and options are used to hedge significant
non-sterling firm commitments or receivables. Gains or losses on these
derivatives are deferred and recognised in the profit and loss account or as
adjustments to carrying amounts, as appropriate when the underlying transaction
is completed.

The Group also enters into interest rate swap transactions in its management of
interest rate exposure. Interest rate swap agreements generally involve the
exchange of fixed and floating interest rate payment obligations without
exchange of the underlying principal amounts. The results of these transactions
are recognised in interest expense in the period hedged by the agreements.

PENSION COSTS

The Group operates a number of pension schemes worldwide, the principal scheme
being that in the United Kingdom, which is of the defined benefits type.
Contributions to this scheme are charged to the profit and loss account so as to
spread the cost of pensions over the employees' working lives within the Group.
The regular cost is attributed to individual years using the projected unit
method. Variations in

                                      IV-5
<PAGE>   109

pension cost, which are identified as a result of actuarial valuations, are
amortised over the average expected remaining working lives of employees.
Differences between amounts funded and the amounts charged to the profit and
loss account are treated as either provisions or prepayments in the balance
sheet.

FIXED ASSETS

Exploration and appraisal expenditure

Exploration expenditure comprises all costs, including premium payments,
associated with the acquisition of new acreage, the drilling of exploratory
wells and other costs incurred in evaluating the commercial viability of
geological entities.

Appraisal expenditure comprises costs incurred in the survey, exploration and
appraisal of license areas not yet under development or in production.

Exploration and appraisal expenditure is classified as an intangible fixed asset
until a decision is reached concerning the commercial viability of the field to
which it relates. Expenditure is then either written off or transferred to
tangible fixed assets. General seismic and other expenditure not connected with
a specific exploration license is written off to the profit and loss account
immediately.

Development expenditure

Development expenditure comprises all costs including financing costs,
exploration and appraisal expenditure incurred in bringing a field to commercial
production and is classified as a tangible asset. No depletion is charged in
respect of development expenditure. Once a field achieves commercial production,
development expenditure is transferred to production assets.

Production assets

Expenditure on production assets represents the Group's share of total
expenditure on the exploration, appraisal and development of oil and gas fields
which are currently in commercial production. This expenditure includes costs of
capital assets, financing costs and general technical and supervisory services
plus, for depletion calculation purposes only, any anticipated further
development expenditure and is stated at cost. Production assets are depleted by
field on a unit of production method, in the proportion of actual production for
the period to the total estimated remaining commercial reserves of the field on
an entitlement basis. The remaining commercial reserves figure is that estimated
at the end of the period plus the production during the period. For depletion
purposes, the separate reservoirs in the Dacion Area in Venezuela are treated as
one field.

Impairment of value

Each year management compares the net book amounts carried in respect of each
field with the estimated recoverable amount. Any impairment of tangible assets
identified is provided for. The estimated recoverable amount is the higher of
the net realisable value and the value in use. The value in use is determined by
reference to estimated future discounted cash flows.

Oil and gas reserves

Proven and probable oil and gas reserves are estimated quantities of
commercially producible hydrocarbons which existing geological, geophysical and
engineering data show to be recoverable in future years from known reservoirs.

Other tangible assets

Office equipment and vehicles are stated at cost less accumulated depreciation,
which is provided so as to write off those assets over their estimated useful
lives, ranging from three to fifteen years.

LEASES

Assets held under leases which result in the Group receiving substantially all
risks and rewards of ownership (capital leases) are capitalised as tangible
fixed assets at the estimated present value of underlying lease payments. The
corresponding capital lease obligation is included with borrowings. Rentals
under operating leases are charged against income as incurred.
                                      IV-6
<PAGE>   110

DECOMMISSIONING PROVISIONS

Provision is made for the cost of decommissioning of Group-owned assets at the
time the obligation to rectify environmental damage arises. Such provision
represents the Group's share of the estimated discounted liability for costs
which may be incurred in removing production platforms and facilities at the end
of the producing life of each field.

EFFECT OF CHANGES IN ESTIMATES

The effect of revisions of previous estimates of proven and probable oil and gas
reserves and of costs is taken up prospectively in unit of production
calculations.

CONSUMABLE STORES

Consumable stores are stated at the lower of cost and net realisable value.

INVESTMENTS

Investments included in current assets are stated at the lower of cost and net
realisable value.

GOODWILL

In accordance with accounting policies extant at the time, goodwill has been
written off to reserves in the year of acquisition. This goodwill would be
charged in the profit and loss account on subsequent disposal of the business to
which it relates. Any goodwill arising from future acquisitions will be
capitalised and amortised over an appropriate period.

Loan capital includes amounts paid and payable to holders of Oil Production
Stock (OPS) units of L0.2 million (1998 L0.2 million; 1997 L0.3 million). These
payments are calculated on 8.75 per cent. of the sales value of production from
8.62608 per cent. of the Ninian field after deducting Government royalties and
operating costs incurred in extracting the oil and conveying and treating it at
Sullom Voe. The Group sold its interest in the Ninian field with effect from 1
January 1994. As part of the consideration, LASMO received unlisted securities
with identical terms to the OPS units. The income from these securities is equal
to the OPS payments and is included within interest receivable and similar
income.

On 17 December 1999 LASMO announced its intention to redeem all of the US $250
million Cumulative Dollar Preference Shares, Series A. The exceptional charge
reflects the premium payable on early redemption or approximately L6 million and
costs of L6 million.

NOTE 11 -- EARNINGS PER SHARE

The calculation of earnings per ordinary share is based on the profit for the
year after minority interests, preference dividends and other appropriations, of
L124 million (1998 loss of L416 million; 1997 profit of L40 million). Earnings
per ordinary share before exceptional items is based on a profit of L95 million
(1998 loss of L56 million; 1997 profit of L40 million). The weighted average
number of ordinary shares in issue for earnings per share was 1,156,702,255
shares (1998 965,966,362; 1997 965,895,800), adjusted by the weighted average
number of own shares held of 13,657,450 shares (1998 15,355,572; 1997
17,289,154), to give 1,143,044,805 (1998 950,610,790; 1997 948,606,646) shares
used in the calculation of earnings per ordinary share. There were 3,859,850
dilutive potential ordinary shares at the end of 1999 (1998 nil; 1997
2,659,880), which were added to the above number in calculating dilutive
earnings per share.

(a) On 10 December 1998 the Group agreed to renegotiate its gas sales agreement
    with PowerGen UK plc. This had the effect of reducing the price of gas
    delivered to PowerGen from 1 October 1998 by approximately 35 per cent. and
    resulted in a payment to LASMO of L146 million, which was received on 5
    January 1999. This has been deferred and is being released to income as gas
    is delivered under the agreement, which terminates in 2013. On 19 October
    1999 the Group modified the gas sales agreement with PowerGen UK plc. This
    had the effect of reducing the gas price by approximately one third for gas
    delivered from 1 June 1999 for a period of five years and resulted in a
    payment to LASMO of L84 million, received in November 1999. This amount is
    being released to income as the gas is delivered over the five year period.
    At 31 December 1999, L31 million (1998 L11 million) is included in accruals
    and deferred income due within one year, and L155 million

     (1998 L115 million) is included in deferred income due after more than one
     year in respect of these arrangements.

(b) Interest is receivable by the Group on PRT refunds which have arisen from
    the carryback of excess current UK North Sea expenditures against prior year
    PRT payments. To the extent that such interest relates to PRT receipts,
    which totalled L6 million (1998 L8 million) arising in respect of the Piper
    field redevelopment, it has been deferred and is being released to income as
    Piper production is received. Also included in deferred income is L8 million
    (1998 L9 million) which relates to a prepayment received under a contract
    for sale of gas. The income is being released to profits as deliveries are
    made.

</TABLE>

The floating rate liabilities bear interest based on six month LIBOR plus 0.8 to
2.1 base points.

Financial assets comprise L384 million of cash and short term investments, and
L12 million of other debtors. Of these items, L354 million is denominated in
sterling, L31 million is denominated in US dollars, and L11 million in other
currencies.

The cash balances bear interest at floating rates based approximately on LIBOR.
Other debtors are non interest bearing and are expected to be recovered within
three years.

iii.   Fair values of financial instruments

The fair value of the Group's financial instruments is as follows:

Market values have been used to determine the fair value of interest rate swaps,
forward foreign currency agreements and listed securities held. The fair value
of all other items have been calculated by discounting the expected future cash
flows at prevailing interest rates at the year end.

iv   Hedging

The Group may, from time to time, use derivative financial instrument to hedge
its exposure to fluctuations in foreign currency exchange rates, interest rates
and crude oil prices. The Group does not become a party to derivatives for
trading purposes. Gains and losses on instruments used for hedging are not
recognised until the exposure that is being hedged is itself recognised.
Unrecognised gains and losses on instruments used for hedging, and the movements
therein, are as follows:

</TABLE>

The extent, if any, to which losses on interest rate swaps will be recognised
beyond 2000 depends upon prevailing interest rates during the period to maturity
of the underlying borrowings, which ranges from 2003 to 2007.

v   Currency profile

The main functional currencies of the Group are sterling and US dollars. In
total, at 31 December 1999 the Group's subsidiaries whose functional currency is
sterling had net monetary assets denominated in US dollars amounting to L38
million.

Deferred PRT

The provision for tax on oil and gas activities is calculated on a unit of
production basis and represents liabilities expected to crystallise on certain
North Sea fields.

<PAGE>   127

Decommissioning costs

The estimated cost of decommissioning at the end of the production lives of
North Sea fields is based upon engineering estimates and expert reports.

Provision is made for the estimated decommissioning costs at the balance sheet
date, discounted to the present value. These liabilities are expected to
crystallise between 2002 and 2019.

</TABLE>

The amount provided in respect of accelerated capital allowances and other
timing differences includes L5 million (1998 L6 million) relating to refunds of
petroleum revenue tax arising from the Piper redevelopment and which are
included in deferred petroleum revenue tax. The potential liability for deferred
taxation excludes revaluation surpluses on certain North Sea fields as these do
not constitute timing differences.

Deferred taxation is not provided in respect of liabilities which might arise on
the distribution of profits of overseas subsidiary companies, due to the
availability of foreign tax credits.

Other

Other provisions principally comprise provisions established in 1998 in respect
of the restructuring of the Group's head office in London and the closure of the
Group's office in Rome.

NOTE 20 -- MINORITY INTEREST

In 1998, LASMO America (LAL) a wholly-owned subsidiary of LASMO plc and
registered in the United States of America issued 1,000,000 series A 8.15 per
cent cumulative perpetual preference shares, each having a par value of $0.01
and a liquidation preference of $100. The shares are redeemable in whole or in
part at the option of LAL at liquidation preference, plus accrued dividends,
after 1 March 2009, or earlier at the option of LAL in the event of certain US
federal income tax law changes. Holders of the shares have a right, in
preference to ordinary shareholders of the Company, to receive on a winding up
the liquidation preference plus any accrued dividends.

NOTE 21 -- PENSION COSTS

The LASMO Group operates a number of pension schemes. The principal scheme is
the LASMO Pension Plan (the Plan) which operates in the United Kingdom and which
is of the funded and defined benefits type. The Plan covers approximately 265
Group employees (1998 415) and its assets are held in trust in a separately
administered fund.

The latest actuarial valuation of the Plan was carried out as at 31 March 1998
and was prepared using the projected unit method. This valuation, which assumed
investment returns of 0.5 per cent. per annum in excess of salary increases and
3.5 per cent. per annum in excess of pension increases, disclosed a funding
level of 123 per cent. The market value of the Plan's assets at the valuation
date was L62 million.
The surplus disclosed by the valuation has been used to reduce the Company
contributions. The pension cost assessed on the basis of actuarial advice and
charged in the financial statements was L2 million (1998 L4 million).

was extracted from the historical financial statements, is included in
Appendices III and IV.

NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS
Millions of US dollars, except per share data

NOTE 1: PRO FORMA ADJUSTMENTS.

The unaudited pro forma financial statements reflect the proposed business
combination using the purchase method of accounting. Based on the purchase
method, assets acquired and liabilities assumed are valued at fair value. The
difference between the purchase price and the fair value of the assets acquired
less the liabilities assumed is recorded as goodwill. The purchase price of the
acquisition is as follows:

</TABLE>

The historical financial statements of LASMO are presented in accordance with
accounting principles generally accepted in the United States. The following pro
forma adjustments reflect estimates and assumptions made by Amerada Hess:

PRO FORMA BALANCE SHEET

(a) To record the projected Amerada Hess cash paid at closing, debt incurred and
    common stock issued to acquire LASMO (see table above).

(b) To record acquired property, plant and equipment and investment in an oil
    and gas corporate joint venture at fair value.

(c)  To record excess of purchase price over fair value of net assets acquired
     (goodwill).

(d) To record additional deferred income taxes of $1,069 resulting from
    acquisition of assets.

(e) To eliminate LASMO's deferred income of $49 from current liabilities and
    $190 from long-term deferred liabilities and credits.

(f)  To eliminate LASMO's stockholders' equity accounts totalling $1,966.

PRO FORMA INCOME STATEMENT

(g) To record interest expense on the revolving credit line used to finance the
     acquisition. The interest rate is assumed to be 7.5%. In calculating the
     pro forma interest expense, Amerada Hess did not assume reductions in debt
     for anticipated future cash flows. A change of 1/8 per cent. in the
     interest rate would result in an annual change in interest expense of
     approximately $3.

(h) To record additional depreciation, depletion and amortization.

(i)  To record amortization of excess of purchase price over fair value of net
     assets acquired (goodwill). Goodwill will be amortized over 15 years.

(j)  To record income tax effects on the pro forma adjustments based on the
     estimated statutory tax rates.

The offer to LASMO Shareholders includes a loan note alternative to cash
consideration. The pro forma financial statements assume that shareholders do
not elect the loan note alternative. The impact of this alternative is not
expected to have a significant effect on the pro forma financial statements.

NOTE 2: COST SAVINGS.

Amerada Hess expects annual cost savings, in the years following integration of
the businesses, of $130 before income taxes and $90 after income taxes. The
unaudited pro forma financial statements do not reflect any anticipated cost
savings or efficiencies resulting from combining operations.

</TABLE>

        The Announcement stated that Amerada Hess had 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. Schroder Investment Management Limited,
        being a fund manager, has given an undertaking to accept the Offer in
        respect of 177,943,047 LASMO Shares insofar as the relevant clients have
        not withdrawn or altered their mandate (in a manner inconsistent with
        acceptance) at the time required for acceptance. Schroder Investment
        Management Limited has notified Amerada Hess that its undertaking
        applies to 171,616,233 LASMO Shares and not 177,943,047 LASMO Shares as
        stated in the Announcement. Therefore, the irrevocable undertakings
        received from the above institutions in fact represent an aggregate of
        269,952,394 LASMO Shares, representing approximately 20.08 per cent. of
        LASMO's issued share capital.

        The directors of LASMO (but not Mr O'Brien) have also irrevocably
        committed to accept the Offer in respect of their holdings of LASMO
        Securities which are set out in (vi) below.

        The number of LASMO Shares the subject of the irrevocable undertakings
        has decreased to 270,276,705 since the Offer was announced.

     (vi)  As at the close of business on    --   December 2000, (being the
           latest practicable date prior to the posting of this document), the
           interests of the LASMO directors and the executive officer and
           members of their immediate families and related trusts in relevant
           securities of LASMO (all of which, unless otherwise stated, are
           beneficial) which have (where required) been notified to LASMO
           pursuant to sections 324 and 328 of the Companies Act and entered in
           LASMO's register of directors' interests required to be kept under
           Section 325 of the Companies Act, were as follows:

5.  PURPOSE OF THE OFFER; PLANS FOR LASMO

PURPOSE OF THE OFFER.  The purpose of the Offer is to enable Amerada Hess to
acquire as many outstanding LASMO Securities as possible as a first step in
acquiring the entire equity interest in LASMO. Upon consummation of a compulsory
acquisition, LASMO would become a wholly owned subsidiary of Amerada Hess.

PLANS FOR LASMO.  Subject to certain matters described below, it is currently
expected that, initially following the consummation of the Offer, the business
and operations of LASMO will generally continue as they are currently being
conducted. Amerada Hess will continue to evaluate all aspects of the business,
operations, capitalisation and management of LASMO during the pendency of the
Offer and after the consummation of the Offer and will take such further actions
as it deems appropriate under the circumstances then existing. Amerada Hess
intends to seek additional information about LASMO during this period.
Thereafter, Amerada Hess intends to review such information as part of a
comprehensive review of LASMO's business, operations, capitalisation and
management.

As a result of the completion of the Offer, the interest of Amerada Hess in
LASMO's net book value and net earnings will be in proportion to the number of
LASMO Securities acquired in the Offer. If the compulsory acquisition is
consummated, Amerada Hess' interest in such items and in LASMO's equity
generally will equal 100 per cent. and Amerada Hess will be entitled to all
benefits resulting from such interest, including all income generated by LASMO's
operations and any future increase in LASMO's value. Similarly, Amerada Hess
will also bear the risk of losses generated by LASMO's operations and

                                      VI-16
<PAGE>   158

any future decrease in the value of LASMO after the compulsory acquisition.
Subsequent to the compulsory acquisition, current LASMO Securityholders will
cease to have any direct equity interest in LASMO and will not have the right to
vote on corporate matters.

When the Offer becomes or is declared unconditional in all respects, Amerada
Hess intends to procure the making of an application by LASMO for the removal of
LASMO Shares from the Official List of the UK Listing Authority and for the
cancellation of trading in LASMO Shares on the London Stock Exchange's market
for listed securities and also for the de-listing of LASMO ADSs and LASMO Shares
(the LASMO Shares do not trade on the NYSE and are listed on the NYSE only in
connection with the ADS program) from the NYSE. It is anticipated that
cancellation of listing from the Official List and cancellation of trading on
the London Stock Exchange will take effect no earlier than 20 business days
after the Offer becomes or is declared unconditional in all respects. See
paragraph 24 of the Letter from Goldman Sachs and paragraph 13 of Appendix VI of
this Offer Document.

It is expected that, if the Offer is not consummated, LASMO's current
management, under the general direction of the current board of directors and
executive management, will continue to manage LASMO as an ongoing business.

Except as otherwise discussed in this Offer Document, Amerada Hess has no
present plans or proposals that would result in any extraordinary corporate
transaction, such as an acquisition, reorganization, liquidation involving LASMO
or any of its subsidiaries, or purchase, sale or transfer of a material amount
of assets of LASMO or any of its subsidiaries or in any other material changes
to LASMO's capitalisation, dividend policy, corporate structure, business or
composition of the board of directors of LASMO or the management of LASMO,
except that Amerada Hess intends to review the composition of the boards of
directors (or similar governing bodies) of LASMO and its subsidiaries and to
cause the election to such boards of directors (or similar governing bodies) and
appointment to executive management of certain of its representatives.

6.  MATERIAL CONTRACTS

(a) The following contracts (not being contracts entered into in the ordinary
     course of business) have been entered into by members of the Amerada Hess
     Group in the period since 6 November 1998 (the date two years prior to the
     commencement of the Offer Period) and are or may be material:

     (i)    An agreement between Amerada Hess and LASMO dated 6 November 2000 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 L24 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 L100
        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.

        The agreement also contains certain confirmations from LASMO to Amerada
        Hess regarding the ownership of Methodplan, the number of Methodplan
        Shares and the ability to use Methodplan Shares to satisfy the exercise
        of share options granted to employees of the LASMO Group under certain
        LASMO Share Option Schemes. LASMO agrees to procure that Methodplan will
        not sell or otherwise dispose of (including pursuant to the Offer) or
        otherwise encumber any Methodplan Shares or acquire any further LASMO
        Shares. LASMO agrees to procure that Methodplan will accept the Offer in
        respect of such shares as Amerada Hess may direct no later than 5
        business days after the date of this document. The agreement also
        contains details regarding how the exercise of share options under the
        LASMO Share Option Schemes and entitlements arising under the LASMO
        Equity Plan are to be satisfied.

        LASMO provides certain confirmations to Amerada Hess regarding the share
        capital of LASMO and the rights of holders under the various LASMO Share
        Option Schemes and the LASMO Equity Plan. LASMO agrees to procure that,
        during the Offer Period, no further

                                      VI-17
<PAGE>   159

        awards or grants of options will be made under the LASMO Share Option
        Schemes or the LASMO Equity Plan and that LASMO will not allot or issue
        any further share capital except as required by the LASMO Share Option
        Schemes. LASMO also agrees not to grant any additional remuneration or
        benefits to any of its senior executives.

        A copy of the inducement agreement is filed as an exhibit to the
        Registration Statement of which this Offer Document constitutes a part.

     (ii)   Under the terms of a letter dated 5 November 2000 from Amerada Hess
        to LASMO, Amerada Hess has agreed to the following arrangements in
        relation to employees including directors of LASMO.

        Amerada Hess has confirmed that it will operate the existing LASMO Early
        Retirement Policy and the LASMO Severance Policy, with its attendant
        benefit continuation provisions, in accordance with their current terms
        and discretions on any termination by the Company of a current LASMO
        employee (other than for cause) within 12 months of the date on which
        the Offer becomes or is declared unconditional in all respects. Amerada
        Hess will honour all contractual notice provisions and will not seek to
        mitigate cash settlement payments due to LASMO staff in respect of any
        contractual notice period.

        Amerada Hess has agreed to LASMO introducing a retention bonus of 25 per
        cent. of basic salary payable to all UK based and expatriate employees
        of LASMO (excluding certain senior executives) for a period commencing
        on 6 November 2000 and ending on the date on which the Offer becomes or
        is declared unconditional in all respects.

        LASMO has agreed that the LASMO Remuneration Committee will review and
        calculate the awards under the LASMO Equity Plan. Amerada Hess will
        accept and implement the decisions of the LASMO Remuneration Committee
        providing those decisions do not involve an annualisation calculation in
        the overall determination of awards.

     (iii)  Under the terms of a letter agreement dated 1 June 2000 between
        LASMO and Amerada Hess, Amerada Hess has agreed on behalf of itself and
        its advisers that it and they will keep secret and confidential any
        confidential information that LASMO provides to any of them in
        connection with the Offer. Amerada Hess has also agreed that it will
        return all records of confidential information that are capable of being
        returned and will destroy all records of confidential information which
        cannot be returned.

        Amerada Hess has also agreed that neither it nor any companies under its
        control, associates, concert parties, professional advisers or directors
        will acquire any shares, or rights over shares, in LASMO without LASMO's
        consent for a period of nine months from the date of the agreement
        unless a third party makes an offer for LASMO.

     (iv)  The directors of LASMO, being Joseph Darby, Thierry Hughes Baudouin
        Jean-Baptiste de Rudder, Paul Colbeck Murray, Roy Gregory Reynolds,
        Nigel Victor Turnbull, Timothy Pienne Brennand, Hugh Edward Norton and
        Antony Peverell Hichens, have given irrevocable undertakings to Amerada
        Hess and Goldman Sachs (the "DIRECTOR UNDERTAKINGS") pursuant to which
        each of the directors of LASMO has undertaken to Amerada Hess that they
        will accept the Offer. Each director has also agreed that, until the
        date on which the Offer ceases to be open for acceptances, each director
        will exercise the voting rights attached to his LASMO Shares
        (representing an aggregate of approximately 0.1 per cent. of the LASMO
        Shares) in connection with certain resolutions relating to the Offer
        only in accordance with Amerada Hess' directions. Each director has also
        undertaken to use his best efforts to procure that LASMO and the LASMO
        board of directors provide all reasonable assistance to Amerada Hess in
        connection with the Offer.

        The terms of the Director Undertakings are the same in all material
        respects except for the amount of LASMO Shares involved and, in certain
        instances, the directors have undertaken in respect of not only existing
        LASMO Shares but LASMO Shares that will be derived from certain option
        plans. Joseph Darby owns 119,458 LASMO Shares and is entitled to receive
        300,869 LASMO Shares pursuant to option plans. Thierry Hughes Baudouin
        Jean-Baptiste de Rudder owns a total of 18,275 LASMO Shares. Paul
        Colbeck Murray owns a total of 65,300 LASMO Shares and is entitled to
        receive 141,039 LASMO Shares pursuant to option plans. Roy Gregory
        Reynolds owns a total of 16,465 LASMO Shares. Nigel Victor Turnbull

                                      VI-18
<PAGE>   160

        owns a total of 32,442 LASMO Shares. Timothy Pienne Brennand owns a
        total of 16,807 LASMO Shares. Hugh Edward Norton owns a total of 12,442
        LASMO Shares. Finally, Antony Peverell Hichens owns a total of 43,122
        LASMO Shares. The Director Undertakings have been filed as exhibits to
        the Registration Statement of which this Offer Document constitutes a
        part and are incorporated herein by reference.

     (v)   Two of LASMO's principal shareholders, Electrafina S.A. and Schroder
        Investment Management Limited, have each given undertakings (the
        "IRREVOCABLE UNDERTAKINGS") to Amerada Hess and Goldman Sachs pursuant
        to which Electrafina S.A. and Schroder Investment Management Limited
        have undertaken to Amerada Hess that they will accept the Offer insofar
        as the relevant clients have not withdrawn or altered their mandate (in
        a manner inconsistent with acceptance) at the time required for
        acceptance. Electrafina S.A. and Schroder Investment Management Limited
        have also agreed that, until the date on which the Offer ceases to be
        open for acceptance, Electrafina S.A. and Schroder Investment Management
        Limited will exercise the voting rights attached to their LASMO Shares
        (such voting rights representing 7.3 per cent. of the entire issued
        capital in the case of Electrafina S.A. and 12.8 per cent. of the entire
        issued capital in the case of Schroder Investment Management Limited) in
        connection with certain resolutions relating to the Offer only in
        accordance with Amerada Hess' directions.

        Electrafina S.A.'s and Schroder Investment Management Limited's
        obligations to accept the Offer will lapse in the event of the
        announcement of an offer by a third party for the fully diluted LASMO
        Shares which is more than one hundred and ten per cent (110 per cent.)
        of the lower of (a) 180p and (b) the Offer as at the close of trading on
        the NYSE trading day immediately preceding such announcement
        (translating the value of new Amerada Hess Shares from U.S. dollars to
        sterling at the exchange rate prevailing at the time).

        The terms of the Irrevocable Undertakings with Electrafina S.A. and
        Schroder Investment Management Limited are the same in all material
        respects except that the Irrevocable Undertaking with Electrafina S.A.
        involves 98,336,161 LASMO Shares and the Irrevocable Undertaking with
        Schroder Investment Management Limited involves 171,616,233 LASMO
        Shares. The irrevocable undertakings have been filed as exhibits to the
        Registration Statement of which this Offer Document constitutes a part
        and are incorporated by reference herein.

(b) The following contracts (not being contracts entered into in the ordinary
     course of business) have been entered into by members of the LASMO Group
     since 6 November 1998 (the date two years prior to the commencement of the
     Offer Period) and are or may be material:

     (i)    an agreement between Amerada Hess and LASMO dated 6 November 2000 as
        an inducement to Amerada Hess to make the Offer and relating to the
        Methodplan Shares and the LASMO Share Option Schemes as referred to in
        paragraph 6(a)(i) above; and

     (ii)   an agreement between Amerada Hess and LASMO dated 5 November 2000
        relating to certain employee arrangements as referred to in paragraph
        6(a)(ii) above.

7.  FINANCING ARRANGEMENTS

It is estimated that full acceptance of the Offer (assuming no LASMO Shareholder
elects for the Loan Note Alternative) would require the payment by Amerada Hess,
under the terms of the Offer, of a maximum cash amount of approximately L1.7
billion. The funds required to make payment under the Offer will be provided by
Amerada Hess in accordance with the following arrangements.

Amerada Hess has entered into two loan agreements (the "CREDIT AGREEMENTS"),
dated 6 November 2000, amended and restated as 14 November 2000, to obtain funds
through two unsecured revolving loan facilities ("CREDIT FACILITY A" and "CREDIT
FACILITY B," hereinafter referred to as the "CREDIT FACILITIES"), to be provided
by the Lenders party to the Credit Agreements and Goldman Sachs Credit Partners
L.P. as joint book runner, joint lead arranger and sole syndication agent, Chase
Securities, Inc. as joint book runner and joint lead arranger and The Chase
Manhattan Bank, N.A., as administrative agent. The total committed funds made
available under the Credit Facilities is $3,000,000,000. Prior to, or
contemporaneously with, borrowing under the Credit Facilities, Amerada Hess
shall have acquired or agreed to acquire, whether pursuant to the Offer or
otherwise, a certain proportion of the voting shares of LASMO. Amerada Hess may
elect borrowings that will bear interest at a rate determined by reference to
the prime rate of a bank to be designated by Amerada Hess or at a rate
determined by reference to
                                      VI-19
<PAGE>   161

LIBOR. There is also a competitive bid loan option which could result in other
interest rates. The Credit Facilities shall terminate on the earlier to occur of
(i) in the case of Credit Facility A, 5 November 2001, and, in the case of
Credit Facility B, 6 November 2005, (ii) the date on which the Offer lapses
(having not been declared unconditional in all respects), is withdrawn, or is
referred to specified European Competition Authorities or (iii) certain
specified dates if the documentation relating to the Offer has not been mailed
prior to such date. There are currently no alternative financing arrangements in
the event the Credit Facilities become unavailable. Amerada Hess has not
concluded arrangements to finance or repay the Credit Facilities but will repay
the Credit Facilities in accordance with the terms of the Credit Agreements. The
Credit Agreements have been filed as exhibits to the Registration Statement of
which this document constitutes a part and are incorporated by reference herein.

Goldman Sachs has indicated that it is satisfied that sufficient resources are
available to Amerada Hess to satisfy full acceptance of the Offer.

effect from 1 April 2000.

Mr. Darby, Mr. Murray and Mr. O'Brien are also entitled to a company car or to
receive a cash allowance in lieu of a car and to full membership of LASMO's
private health insurance scheme, which also covers their wives and any dependent
children.

Services of Antony Hichens

Mr. Hichens is engaged as Chairman of LASMO under an agreement with LASMO dated
5 May 2000. Under the terms of the agreement, the engagement of Mr. Hichens may
be terminated by the Company or Mr. Hichens giving not less than 12 months'
written notice.

Mr. Hichens receives fees of L200,000 per annum.

Save as disclosed in this paragraph 8, there are no service contracts between
any director of LASMO and LASMO or any subsidiary of LASMO having more than 12
months to run and no such contract has been entered into or amended or replaced
within 6 months preceding the date of this document.

EQUITY PLAN

Mr. Darby, Mr. Murray and Mr. O'Brien participate, together with a restricted
population of the Company's most senior executives, in the Equity Plan. Mr.
Darby, Mr. Murray and Mr. O'Brien are entitled to acquire (for no consideration)
a number of LASMO Shares allocated to them under the Equity Plan. The allocation
has been based on a percentage of salary and calculated by reference to share
price.

                                      VI-20
<PAGE>   162

Subject to the satisfaction of two performance targets, the actual number of
LASMO Shares (if any) which may be released to each participant in respect of
any Equity Plan year is determined after the end of the three year performance
period. The performance targets operate as follows: first, the number of LASMO
Shares notionally allocated to a participant will be adjusted so that, on a
sliding scale, 100 per cent. is carried forward if there is an increase in the
LASMO share price of 2.5 per cent. per annum over the percentage increase in the
Retail Prices Index (All items) over the performance period, with a further 100
per cent. for each additional 5 per cent. per annum increase over the percentage
increase in the Retail Prices Index (All items). The increased number is then
adjusted by a multiple which is determined by comparing the total shareholder
return of LASMO over the performance period (change in share price plus
re-invested dividends) relative to the total shareholder return of a comparator
group of 11 international oil and gas exploration and production companies (the
"Comparator Group") of LASMO over the performance period to LASMO ordinary
shareholders against the Comparator Group.

On a change of control of LASMO the performance period under the Plan is deemed
to end on the date of change of control or such other date as the Remuneration
Committee may decide. The calculation of entitlements under the Plan will be
based upon share price growth and relative performance against the peer group up
to the date of the change of control. Although individual entitlements, can only
be determined once that date is known, the Remuneration Committee's estimates of
the likely entitlements of Mr. Darby, Mr. Murray and Mr. O'Brien under the Plan
(which it is proposed to satisfy in cash, in accordance with the Rules of the
Plan) are    --   ,    --   and    --   LASMO Shares respectively.

ANNUAL BONUS

Mr. Darby, Mr. Murray and Mr. O'Brien are eligible to receive a bonus under the
annual bonus scheme, which rewards the achievement of challenging targets set in
advance and related to the short term performance of the business and personal
objectives. Targets are set through the annual performance appraisal process and
include achievement of quantifiable performance elements. A maximum bonus of 60
per cent. of base salary may be paid where exceptional performance is achieved.
All annual bonus payments are non-pensionable.

SHARE OPTION SCHEMES

Options over ordinary shares in the Company have been granted to Mr. Darby, Mr.
Murray and Mr. O'Brien under the LASMO Share Option Scheme, formerly known as
the LASMO 1984 Executive Share Option Scheme (the "LASMO SCHEME") and the LASMO
International Share Option Scheme, formerly known as the LASMO International
Executive Share Option Scheme (the "INTERNATIONAL SCHEME"). Such options are
normally exercisable between three and ten years after grant. The LASMO Scheme
is an Inland Revenue approved scheme. The International Scheme is unapproved,
with UK and overseas executives eligible to participate. Options may be granted
at not less than the market value of an ordinary share of the Company on the
date of grant. The aggregate price payable by a participant on the exercise of
all options under the LASMO Scheme, the International Scheme and the closed
LASMO Executive Share Option Scheme established in 1980 (the "1980 SCHEME"), in
any ten year period, may not exceed four times such participant's annual
earnings. The Company's policy has been that, whilst higher awards may be given
to reward exceptional individual performance, the grant of options to an
individual at any one time should not normally exceed an amount equivalent to 40
per cent. of that individual's annual earnings.

The exercise of options granted under the LASMO Scheme and the International
Scheme since April 1995, has been subject to the achievement of specified total
shareholder targets relative to the total shareholder return of a group of
comparator companies.

The performance target need not be satisfied where options are exercised
following a change of control in LASMO (as defined under the rules of the
relevant plan).

No options have been granted under the LASMO Share Option Schemes to Mr. Darby
and Mr. Murray since 1995 because they are eligible to participate in the LASMO
Equity Plan.

SAYE SHARE OPTION SCHEME

Mr. Darby, Mr. Murray and Mr. O'Brien are participants in the SAYE Share Option
Scheme and are invited to save up to L250 a month for three or five years to
acquire LASMO Shares at not less than 80 per cent. of the mid-market price of a
LASMO Share on the business day preceding the invitation date.

9.  BACKGROUND TO THE OFFER

On 26 January 2000, John B. Hess, Chairman of the Board and Chief Executive
Officer of Amerada Hess, and W. S. H. Laidlaw, President and Chief Operating
Officer of Amerada Hess, met with Rudolph Agnew, then Chairman of LASMO and
Joseph Darby, Chief Executive Officer of LASMO, to discuss the possible sale of
part of LASMO's interest in the Dacion project in Venezuela and LASMO's
properties in Algeria. During this meeting, the issue of possible broader
combinations, including the sale of all the share capital of LASMO to Amerada
Hess, was raised in general terms without being pursued further. This meeting
followed an earlier meeting on 22 December 1999 between Mr. Laidlaw and Mr.
Darby to discuss LASMO's Venezuelan and Algerian assets, during which Mr.
Laidlaw and Mr. Darby agreed that it would be appropriate for their respective
Chairmen, Mr. Hess and Mr. Agnew, to meet to discuss possibilities for the two
companies to work together.

During the period from February to April 2000, Amerada Hess personnel visited
LASMO data rooms and attended presentations relating to LASMO's Venezuelan and
Algerian assets. On 30 April 2000, Messrs. Hess and Laidlaw met again with
Messrs. Agnew and Darby. At this meeting, Amerada Hess made an indicative offer
for 50 per cent. of the Dacion asset and also discussed generally the
possibility of a broader combination of the two companies. The representatives
of LASMO indicated support for a broader combination in concept but noted that
Mr. Agnew was retiring.

On 21 May 2000, Messrs. Hess and Laidlaw met with LASMO's new Chairman, Antony
Hichens. Mr. Hichens indicated that the Dacion offer was not acceptable but
expressed interest in a combination of the two companies. He agreed to limited
due diligence for the purpose of permitting Amerada Hess to formulate a bid. On
30 May 2000, Amerada Hess signed a confidentiality agreement which included a
standstill agreement not to pursue an unsolicited bid for LASMO through 1
December 2000 (subsequently extended to 1 March 2001). Soon thereafter, Amerada
Hess personnel met with LASMO personnel to conduct limited due diligence.

On 6 June 2000, Amerada Hess received a letter from Schroder Salomon Smith
Barney, financial advisor for LASMO, outlining the terms that LASMO would expect
to be addressed in a formal offer for LASMO. On 20 June 2000 Mr. Hess met with
Mr. Hichens in London and submitted an offer for the acquisition by Amerada Hess
of the outstanding capital stock of LASMO for approximately 2/3 cash and 1/3
Amerada Hess common stock. Mr. Hichens declined the offer on the grounds of
insufficient price.

On 28 June 2000, Mr. Hess telephoned Mr. Hichens and offered an increased price,
with the same percentage combination of cash and stock. Mr. Hichens responded
with a counter proposal which Amerada Hess deemed unacceptable as it would have
effectively increased the per share purchase price by a substantial amount.

On 5 July 2000, Mr. Hess received a letter from Mr. Hichens restating the price
he would accept, which in Amerada Hess' view did not indicate any movement. On 7
July 2000, Mr. Hess made a final offer. On 12 July 2000 Mr. Hichens rejected a
final bid and discussions for the purchase of LASMO ended. However, each
chairman left open the possibility of continuing to explore the possibility of
Amerada Hess acquiring an interest in Dacion.

Throughout late July and August 2000, discussions continued concerning the
acquisition by Amerada Hess of a 50 per cent. interest in Dacion. Amerada Hess'
first offer, made on 10 August 2000 was rejected by LASMO. Amerada Hess
subsequently revised that offer to increase its bid, but on 29 September 2000,
Mr. Darby telephoned Mr. Laidlaw to say that the Dacion offer was unlikely to be
acceptable to the LASMO Board and that the LASMO Board was considering its
strategic alternatives. On 9 October, Mr. Darby confirmed to Mr. Laidlaw that
Amerada Hess' bid for the Dacion interest was not likely to be acceptable to
LASMO's Board. On 10 October, Mr. Hess telephoned Mr. Hichens to express his
continuing hope that Amerada Hess' bid for the Dacion interest would be accepted
and his view that this joint venture would be the basis for the two companies to
work together.

                                      VI-22
<PAGE>   164

On a telephone call on 12 October 2000, Mr. Hess and Mr. Hichens agreed to
re-open discussions on the acquisition of LASMO. Mr. Hess requested that Mr.
Hichens make a clear statement of LASMO's position which had the full support of
the LASMO Board. On 19 October 2000, Mr. Hichens, in a telephone call to Mr.
Hess, outlined a proposal which he stated the LASMO Board would find acceptable
for the purchase by Amerada Hess of all the outstanding shares of LASMO,
including a cash component and a share component based on a fixed exchange
ratio. Mr. Hess indicated that he would study the proposal and review it with
the Amerada Hess Board.

Following this call, Amerada Hess formulated a new bid. Amerada Hess' management
concluded that due principally to favourable movements in the dollar/sterling
exchange rate and increases in crude prices since 12 July 2000, the date at
which negotiations had previously ended, Amerada Hess was in a position to
increase its bid. Management concluded that it could further reduce the risk of
the higher bid price by hedging the foreign currency exchange exposure and could
hedge the risk to future cash flows by selling forward a substantial portion of
LASMO's anticipated crude oil production for 2001 at the current favourable
market prices.

Amerada Hess management reviewed the revised bid with its Board on 25 October
2000, and the Amerada Hess Board authorised Mr. Hess to make the proposal to
LASMO. On 26 October 2000, Mr. Hess presented a revised bid to Mr. Hichens of
180 pence per share, with a fixed exchange ratio of 1 share of Amerada Hess
stock for every 78.7 shares of LASMO stock using an Amerada Hess share closing
price on the date immediately preceding announcement, with the remainder of the
consideration to be paid in cash. Mr. Hess noted that the bid was subject to
final confirmatory due diligence. Mr. Hichens indicated that he approved the
revised bid and would recommend the offer to his Board. On 27 October 2000, Mr.
Darby notified Mr. Hess that the LASMO Board had unanimously approved the offer,
subject to satisfactory negotiation of final documentation.

Commencing the week of 30 October 2000, Amerada Hess conducted final due
diligence and, in consultation with LASMO, finalised documentation in
preparation for the Announcement on 6 November 2000. The transaction was given
final approval by the Amerada Hess Board on 5 November 2000. A committee of the
LASMO Board gave final approval to the Offer on 5 November 2000, having been
duly authorized to do so by the full Board.

10. RIGHTS ATTACHING TO NEW AMERADA HESS SHARES TO BE ISSUED AS CONSIDERATION
    UNDER THE OFFER

The new Amerada Hess Shares will rank pari passu in all respects with existing
Amerada Hess common stock, including the right to any dividends and other
distributions declared, paid or made by reference to a record date after the
date on which they are issued. For the avoidance of doubt, LASMO Securityholders
will not be entitled to 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 will be delivered in accordance with the terms of
the Offer and will be fully paid and free from all liens, equities, charges,
equitable interests, encumbrances and other interests (other than those created
by a LASMO Securityholder) and together with all rights now or hereafter
attaching thereto.

The sterling value of any investment in Amerada Hess Shares and any dividend
income from that investment (payable in US dollars and subject to US withholding
tax) will be affected by the dollar to sterling exchange rate from time to time.

The new Amerada Hess Shares are expected to be authorised for listing, subject
to official notice of issuance, on the NYSE, but they will not be listed or
traded on the London Stock Exchange or any other stock exchange.

11. COMPULSORY ACQUISITION

If, within four months after the date of this document, as a result of the Offer
or otherwise, Amerada Hess acquires or contracts to acquire LASMO Securities
representing at least 90 per cent. in nominal value of LASMO Shares (including
LASMO Shares represented by LASMO ADSs) to which the Offer relates, then:

     (i)    Amerada Hess will be entitled and intends to effect the compulsory
        acquisition procedures provided for in sections 428 to 430F of the
        Companies Act (set out in Appendix VIII to this document) to compel the
        purchase of any outstanding LASMO Securities on the same terms

                                      VI-23
<PAGE>   165

        as provided in the Offer in accordance with the relevant procedures and
        time limits described in the Companies Act; and

     (ii)   a holder of LASMO Securities may require Amerada Hess to purchase
        his LASMO Securities on the same terms as provided in he Offer in
        accordance with the relevant procedures and time limits described in
        section 430A of the Companies Act.

If, for any reason, the above mentioned compulsory acquisition procedures are
not invoked, Amerada Hess will evaluate other alternatives to obtain the
remaining LASMO Securities not purchased pursuant to the Offer or otherwise.
Such alternatives could include acquiring additional LASMO Securities in the
open market, in privately negotiated transactions, through another offer to
purchase, by means of a scheme of arrangement under the Companies Act or
otherwise. Any such additional acquisitions could be for a consideration greater
or less than, or equal to, the consideration for LASMO Securities under the
Offer. However, under the City Code, except with the consent of the Panel,
Amerada Hess may not acquire any LASMO Securities on better terms than those of
the Offer within six months of termination of the Offer if Amerada Hess,
together with any persons acting in concert with it (as defined by the City
Code), holds shares carrying more than 50 per cent. of the voting rights
normally exercisable at general meetings of LASMO.

Holders of LASMO Securities do not have appraisal rights as a result of the
Offer. However, in the event that the compulsory acquisition procedures referred
to above are available to Amerada Hess, holders of LASMO Securities whose LASMO
Securities have not been purchased pursuant to the Offer will have certain
rights to object under section 430C of the Companies Act.

12. REGULATORY APPROVALS

(A) UK MERGER CONTROL

     Under the City Code, it is a mandatory term of a UK public offer that the
     offer will lapse if the Secretary of State for Trade and Industry
     ("SECRETARY OF STATE") should refer the offer to the Competition Commission
     prior to consummation of the offer. While notification to the Office of
     Fair Trading ("OFT") is voluntary, the OFT may, of its own accord, initiate
     a review into a transaction where it considers that the transaction will
     qualify for investigation within the meaning of the Fair Trading Act 1973
     ("FTA"). Such a review may be initiated at any time up to four months
     following public announcement of a completed transaction.

     As the Offer gives rise to a merger situation qualifying for investigation
     within the meaning of the FTA, the Offer has been made conditional on it
     being indicated, on terms satisfactory to Amerada Hess, that the Secretary
     of State does not intend to refer the Offer to the Competition Commission.

     Amerada Hess submitted a statutory merger notice to the OFT on 22 November
     2000. The OFT has an initial period of 20 working days, which began on 23
     November 2000, in which to review the transaction following which the
     Secretary of State will issue his decision as to whether to refer the Offer
     for investigation by the Competition Commission. This period is due to
     expire at midnight on 20 December 2000. The OFT is entitled, however, to
     extend this initial review period by a further 15 working days, in which
     case the review period would expire at midnight on 15 January 2001. If,
     following the expiry of the relevant period, no decision has been taken to
     refer the Offer to the Competition Commission, the Offer will be deemed to
     have been cleared. In the event that the Offer is referred to the
     Competition Commission, the Offer will lapse.

     During the initial review period, the OFT may request further information
     on the notified transaction, and will seek comments from third parties. The
     OFT will also announce its review of the Offer on the London Stock
     Exchange's Regulatory News Service and invite comments from third parties
     within a specified period. The OFT may contact major customers and
     competitors of the parties. Should the OFT conclude that the Offer gives
     rise to substantive competition or other public interest concerns, it will
     also seek the views of the Mergers Panel, a non-statutory body on which all
     interested governmental departments are represented. In any event, the OFT
     will, following its initial review of the Offer, submit a written
     recommendation to the Secretary of State. The Secretary of State, who is
     not obliged to follow the recommendation of the OFT, will then issue his
     decision as to whether the Offer will be referred for an in-depth
     investigation by the Competition Commission. While Amerada Hess does not
     consider that the Offer will give rise to any substantive competition
     issues, there can be no assurance that the Offer will not be referred to
     the Competition Commission.
                                      VI-24
<PAGE>   166

(B) US ANTITRUST

     Under the HSR Act and the rules that have been promulgated thereunder by
     the Federal Trade Commission ("FTC"), certain mergers and acquisitions may
     not be consummated unless certain information has been furnished to the
     Antitrust Division of the Department of Justice (the "Antitrust Division")
     and the FTC and certain waiting period requirements have been satisfied.
     The acquisition of the LASMO Securities by Amerada Hess pursuant to the
     Offer is subject to the HSR Act requirements.

     Under the provisions of the HSR Act applicable to the purchase of the LASMO
     Securities pursuant to the Offer, such purchase may not be made until the
     expiration of a thirty calendar day waiting period following the required
     filing of a Notification and Report Form under the HSR Act by Amerada Hess,
     which Amerada Hess intends to submit on or around 30 November 2000.
     Accordingly, the waiting period under the HSR Act will expire at 11:59 PM,
     New York City time, on the thirtieth calendar day following filing of the
     Notification and Report Form by Amerada Hess unless early termination of
     the waiting period is granted or Amerada Hess receives a request for
     additional information or documentary material prior thereto. If either the
     FTC or the Antitrust Division were to request additional information or
     documentary material from Amerada Hess prior to the expiration of the
     thirty day waiting period, the waiting period would be extended and would
     expire at 11:59 PM, New York City time, on the twentieth calendar day after
     the date of substantial compliance by Amerada Hess with such request.
     Thereafter, the waiting period could be extended only by court order or by
     consent of Amerada Hess. If the acquisition of the LASMO Securities is
     delayed pursuant to a request by the FTC or the Antitrust Division for
     additional information or documentary material pursuant to the HSR Act, the
     purchase of and payment for the LASMO Securities pursuant to the Offer will
     be deferred until twenty days after the request is substantially complied
     with unless the waiting period is terminated sooner by the FTC or the
     Antitrust Division (and assuming all of the other Offer conditions have
     been satisfied or waived). Only one extension of such waiting period
     pursuant to a request for additional information or documentary material is
     authorized by the rules promulgated under the HSR Act, except by court
     order or by consent. Although LASMO is required to file certain information
     and documentary material with the Antitrust Division and the FTC in
     connection with the Offer, neither LASMO's failure to make such filings nor
     a request to LASMO from the Antitrust Division or the FTC for additional
     information or documentary material will extend the waiting period.
     However, if the Antitrust Division or the FTC raises substantive issues in
     connection with a proposed transaction, the parties frequently engage in
     negotiations with the relevant governmental agency concerning possible
     means of addressing these issues and may agree to delay consummation of the
     transaction while such negotiations continue.

     The Antitrust Division and the FTC frequently scrutinize the legality under
     the antitrust laws of transactions such as the proposed acquisition of the
     LASMO securities by Amerada Hess pursuant to the Offer. At any time before
     or after Amerada Hess' purchase of the LASMO Securities, either the
     Antitrust Division or the FTC could take such action under the antitrust
     laws as it deems necessary or desirable in the public interest, including
     seeking to enjoin the acquisition of the LASMO securities pursuant to the
     Offer or seeking divestiture of the LASMO Securities acquired by Amerada
     Hess or divestiture of substantial assets of Amerada Hess, LASMO or any of
     their respective subsidiaries. State attorneys general may also bring legal
     action under the antitrust laws, and private parties may bring such action
     under certain circumstances. Amerada Hess believes that the acquisition of
     the LASMO Securities by Amerada Hess will not violate the antitrust laws.
     Nevertheless, there can be no assurance that a challenge to the Offer on
     antitrust grounds will not be made or, if a challenge is made, what the
     result will be. See Appendix I for certain conditions to the Offer,
     including conditions with respect to litigation and certain governmental
     actions.

13. CERTAIN CONSEQUENCES OF THE OFFER

(A) MARKET EFFECT

     The past performance of the price of LASMO Shares and LASMO ADSs is no
     guide to the future performance of LASMO Securities.

     The purchase of LASMO Securities pursuant to the Offer will reduce the
     number of holders of LASMO Securities and the number of LASMO Securities
     that might otherwise trade publicly and, depending upon the number of LASMO
     Securities so purchased, could adversely affect the liquidity
                                      VI-25
<PAGE>   167

     and market value of the remaining LASMO Securities held by the public. In
     addition, when the Offer becomes or is declared unconditional in all
     respects, Amerada Hess intends to procure the making of an application by
     LASMO for the removal of LASMO Shares from the Official List of the UK
     Listing Authority and for the cancellation of trading in LASMO Shares on
     the London Stock Exchange's market for listed securities and also for the
     de-listing of LASMO ADSs and LASMO Shares (the LASMO Shares do not trade on
     the NYSE and are listed on the NYSE only in connection with the ADS
     program) from the NYSE. It is anticipated that cancellation of listing from
     the Official List and cancellation of trading on the London Stock Exchange
     will take effect no earlier than 20 business days after the Offer becomes
     or is declared unconditional in all respects. While it is anticipated that
     cancellation of both listings will take place at the same time,
     cancellation of the listing of the LASMO ADSs and LASMO Shares on the NYSE
     could take effect earlier than cancellation of the listing of the LASMO
     Shares on the London Stock Exchange. Amerada Hess also intends that LASMO
     should terminate the LASMO ADR facility in accordance with the deposit
     agreement relating thereto and terminate the registration of the LASMO ADSs
     and LASMO Shares under the Exchange Act.

     The value of all investments and the outcome from them can fall as well as
     rise and not all the amount invested may be realised. LASMO Securityholders
     accepting the Offer and electing to receive consideration in US dollars
     should be aware that they will be exposed to foreign currency risk.

(B) PUBLIC AVAILABILITY OF INFORMATION

     In the event that LASMO Shares continue to be listed on the London Stock
     Exchange following the Offer becoming or being declared unconditional,
     holders of LASMO Shares who have not accepted the Offer will continue to
     receive the same financial and other information from LASMO that LASMO is
     presently required by the rules of the London Stock Exchange to send to
     such holders. If LASMO Shares are no longer listed on the London Stock
     Exchange following the Offer, LASMO would no longer be required by those
     rules to make publicly available such financial and other information.

     The LASMO ADSs and the LASMO Shares (not for trading but in support of the
     LASMO ADSs) are currently registered under the Exchange Act. Registration
     of such LASMO ADSs and LASMO Shares may be terminated upon application of
     LASMO to the SEC if LASMO ADSs are neither listed on a national securities
     exchange nor held by 300 or more beneficial owners in the US. Termination
     of registration of LASMO ADSs and LASMO Shares under the Exchange Act would
     substantially reduce the information required to be furnished by LASMO to
     holders of LASMO ADSs and to the SEC and would make certain provisions of
     the Exchange Act, such as the requirements of Rule 13e-3 thereunder with
     respect to "going private" transactions, no longer applicable to LASMO.
     Furthermore, "affiliates" of LASMO and persons holding "restricted
     securities" of LASMO may be deprived of the ability to dispose of such
     securities pursuant to Rule 144 promulgated under the Securities Act. If,
     as a result of the purchase of LASMO ADSs pursuant to the Offer and prior
     to completing the compulsory acquisition procedures referred to in
     paragraph 11 above, LASMO is not required to maintain registration of LASMO
     ADSs and LASMO Shares under the Exchange Act, Amerada Hess intends to cause
     LASMO to apply for termination of such registration. If registration of
     LASMO ADSs and LASMO Shares is not terminated prior to completion of the
     aforementioned compulsory acquisition procedures, then, following
     completion of the aforementioned compulsory acquisition procedures, LASMO
     ADSs will cease trading on the NYSE and the registration of LASMO ADSs and
     LASMO Shares under the Exchange Act would be terminated.

(C) MARGIN SECURITIES

     LASMO ADSs and LASMO Shares are currently "margin securities" under the
     regulations of the board of Governors of the US Federal Reserve System,
     which status has the effect, among other things, of allowing US brokers to
     extend credit on the collateral of LASMO ADSs and LASMO Shares for purposes
     of buying, carrying and trading in securities ("PURPOSE LOANS"). Depending
     on factors such as the number of holders of record LASMO ADSs and LASMO
     Shares and the number and market value of publicly held LASMO ADSs and
     LASMO Shares following the purchase of LASMO Securities pursuant to the
     Offer, it is possible that LASMO ADSs and LASMO Shares would no longer be
     eligible for listing on the NYSE. As a result, LASMO ADSs and LASMO

                                      VI-26
<PAGE>   168

     Shares might no longer constitute margin securities and, therefore, could
     no longer be used as collateral for Purpose Loans made by US brokers.

14. UNITED KINGDOM TAXATION

The statements below summarise advice received by the Directors of Amerada Hess
in relation to certain aspects of the UK tax treatment and consequences of the
Offer for LASMO Shareholders. They are intended only as a general guide to
current UK tax law and practice for LASMO Shareholders who are resident or
ordinarily resident in the UK for tax purposes, who are the beneficial owners of
their LASMO Shares and who hold them as investments. ANY PERSON WHO IS IN ANY
DOUBT AS TO HIS TAX POSITION OR WHO MAY BE SUBJECT TO TAX IN ANY JURISDICTION
OUTSIDE THE UK SHOULD CONSULT AN APPROPRIATE PROFESSIONAL ADVISER.

(A) UK TAXATION OF CHARGEABLE GAINS ("CGT")

     Liability to CGT will depend on the particular circumstances of LASMO
     Shareholders and on the form of consideration received.

(i)  Cash

     An accepting LASMO Shareholder will generally, to the extent that he
     receives cash under the Offer, be treated as effecting a disposal or part
     disposal of his LASMO Shares for the purposes of CGT and may, depending on
     his individual circumstances, incur a liability to CGT. Special rules apply
     for the purposes of CGT where a holder of LASMO Shares receives cash and
     new Amerada Hess Shares and/or Loan Notes, and the amount of cash received
     is "small" compared with the value of his LASMO Shares. For these purposes
     the receipt of an amount of cash of five per cent. or less of the market
     value of the LASMO Shares will be treated as "small". The Inland Revenue
     will also accept that an amount in cash is "small" if it is L3,000 or less,
     even if it exceeds five per cent. of the market value of the LASMO Shares
     in respect of which it is received. In such cases there will generally be
     no disposal or part disposal of the holder's LASMO Shares in respect of the
     receipt of cash. The amount of the cash received will instead be deducted
     from the LASMO Shareholder's allowable expenditure in computing a
     chargeable gain or allowable loss on a subsequent disposal of new Amerada
     Hess Shares or Loan Notes.

(ii)  Receipt of new Amerada Hess Shares and Loan Notes

     A LASMO Shareholder not holding (either alone or together with persons
     connected with him) more than five per cent. of LASMO Shares or any other
     class of shares in or debentures of LASMO should not, to the extent that he
     receives new Amerada Hess Shares or Loan Notes under the Offer, be treated
     as having made a disposal of LASMO Shares for the purposes of taxation of
     chargeable gains. Any chargeable gain or allowable loss which would
     otherwise have arisen on a disposal of his LASMO Shares will, in the case
     of an individual or other non-corporate shareholder, be "rolled-over" into
     the new Amerada Hess Shares and the Loan Notes, and the new Amerada Hess
     Shares and the Loan Notes, as the case may be, will be treated as the same
     asset as his LASMO Shares acquired at the same time and for the same
     consideration as he acquired his LASMO Shares.

     To the extent that such a LASMO Shareholder which is within the charge to
     corporation tax receives new Amerada Hess Shares, any chargeable gain or
     allowable loss which would otherwise have arisen on a disposal of its LASMO
     Shares will be "rolled-over" into the new Amerada Hess Shares and the new
     Amerada Hess Shares will be treated as the same asset as its LASMO Shares
     acquired at the same time and for the same consideration as it acquired its
     LASMO Shares. To the extent that it receives Loan Notes, any chargeable
     gain or allowable loss which would otherwise have arisen on a disposal of
     its LASMO Shares for a consideration equal to market value at the time of
     the exchange of the LASMO Shares for Loan Notes will be "held-over" and
     deemed to accrue on a subsequent disposal (including on redemption or
     repayment) of the Loan Notes.

     Any LASMO Shareholder who holds (either alone or together with persons
     connected with him) more than five per cent. of LASMO Shares or any other
     class of shares in, or debentures of, LASMO is advised that an application
     for clearance will be made to the Inland Revenue under Section 138 of the
     Taxation of Chargeable Gains Act 1992 in respect of the Offer, although
     receipt

                                      VI-27
<PAGE>   169

     of such clearance is not a condition of the Offer. Provided such clearance
     is given, any such shareholder will be treated in the manner described in
     the preceding paragraphs.

(iii) Disposal of new Amerada Hess Shares or Loan Notes

     A subsequent disposal of new Amerada Hess Shares or of Loan Notes
     (including on redemption or repayment) may result in a liability to UK
     taxation of chargeable gains.

     For a LASMO Shareholder who is an individual or other non-corporate
     shareholder, the Loan Notes should not constitute qualifying corporate
     bonds for the purposes of UK taxation of chargeable gains. Accordingly, any
     chargeable gain or allowable loss on disposal (including on redemption or
     repayment) of the Loan Notes should, in the same way as any chargeable gain
     or allowable loss on the disposal of new Amerada Hess Shares, be calculated
     taking into account the allowable original cost to the holder of acquiring
     the relevant LASMO Shares. Indexation allowance on that cost should be
     available (when calculating a chargeable gain but not an allowable loss) in
     respect of the period of ownership of the LASMO Shares up to April 1998.
     Thereafter, taper relief may be available to reduce the amount of
     chargeable gain realised on the subsequent disposal. In broad terms it is
     expected that the allowable original cost of the relevant LASMO Shares will
     be apportioned to the new Amerada Hess Shares and/or the Loan Notes and/or
     the cash received, according to their respective market values at the time
     of the exchange of the LASMO Shares.

     For a LASMO Shareholder within the charge to corporation tax, the Loan
     Notes will be qualifying corporate bonds for the purposes of UK taxation of
     chargeable gains. Accordingly, no indexation allowance will be available
     for the period of ownership of the Loan Notes and, except to the extent
     that any chargeable gain or allowable loss which would otherwise have
     arisen on the disposal of its LASMO Shares was "held over" and crystallises
     on the subsequent disposal as described above, no chargeable gain or
     allowable loss shall arise. For a LASMO Shareholder within the charge to
     corporation tax, any chargeable gain or allowable loss on the subsequent
     disposal of new Amerada Hess Shares should be calculated taking into
     account the original cost to the holder of acquiring the relevant LASMO
     Shares and (when calculating a chargeable gain but not an allowable loss)
     indexation allowance on that cost. In broad terms it is expected that the
     allowable original cost of the relevant LASMO Shares will be apportioned to
     the new Amerada Hess Shares and/or the Loan Notes and/or the cash received,
     according to their respective market values at the time of the exchange of
     the LASMO Shares.

(B) TAXATION OF DIVIDENDS PAID ON NEW AMERADA HESS SHARES

     Holders will, in general, be subject to UK income tax or corporation tax on
     the gross amount of dividends paid on the new Amerada Hess Shares. An
     individual shareholder will generally be chargeable to income tax on such
     dividends at the Schedule F ordinary rate (currently 10 per cent.) or, to
     the extent that his or her income exceeds the threshold for higher rate
     tax, at the Schedule F upper rate (currently 32.5 per cent.). Credit will
     be available against income or corporation tax for any United States tax
     required to be deducted or withheld from the dividends, provided that such
     credit will not exceed the credit which would have been allowed had all
     reasonable steps been taken (including any claims which could be made by
     the holder under the terms of the double taxation agreement between the
     United States and the United Kingdom) to minimise such United States tax.

     In relation to any dividends paid on the new Amerada Hess Shares prior to 1
     April 2001, where a person in the United Kingdom in the course of a trade
     or profession either:

     (i)    acts as custodian of the new Amerada Hess Shares and receives such
        dividends, or directs that such dividends be paid to another person, or
        consents to such payment; or

     (ii)   collects or secures payment of or receives such dividends for a
        holder; or

     (iii)  otherwise acts for another person in arranging to collect or secure
        payment of such dividends for such a person;

     except by means only of clearing a cheque or arranging for the clearing of
     a cheque, that person (the "COLLECTING AGENT") is liable to account for
     income tax at the Schedule F ordinary rate (currently 10 per cent.) on such
     dividends (subject to giving credit for any United States tax required

                                      VI-28
<PAGE>   170

     to be deducted or withheld from the dividends) and is entitled to deduct an
     amount in respect thereof unless an exemption from such liability is
     applicable, including, for example, where:

     (i)    the person beneficially entitled to the such dividends beneficially
        owns the new Amerada Hess Shares and is not resident in the United
        Kingdom; or

     (ii)   the dividends arise to trustees not resident in the United Kingdom
        of certain discretionary or accumulation trusts (where, inter alia, none
        of the beneficiaries of the trust is resident in the United Kingdom); or

     (iii)  the person beneficially entitled to the dividends is eligible for
        certain relief from tax in respect of the dividends (for example,
        charities or pension funds).

        In the case of each of the above exceptions (I) to (III), conditions
        imposed by regulations may have to be satisfied for the relevant
        exception to be available. Where income tax is deducted it will be paid
        to the Inland Revenue. The tax deducted will be credited against the
        holder's liability to the UK income tax or corporation tax; in
        appropriate cases, holders will be liable to a higher rate of income tax
        in addition to the tax deducted, or will be entitled to a refund where
        the amount deducted exceeds their liability to UK taxation.

        The obligation on persons in the United Kingdom who pay or collect
        dividends to account for withholding tax in certain circumstances as
        described above will cease to apply in relation to payments made on or
        after 1 April 2001.

        Persons paying or receiving dividends on or after 6 April 2001 may be
        required to provide certain information to the Inland Revenue, which
        could include the name and address of the person beneficially entitled
        to the dividends.

(C) LASMO SHARE OPTION SCHEMES

     Special tax provisions may apply to LAMSO Shareholders who acquired their
     LASMO Shares by exercising options under the LASMO Share Option Schemes,
     including provisions imposing a charge to income tax.

(D) TAXATION OF INTEREST ON THE LOAN NOTES

     Holders will, in general, be subject to UK income tax or corporation tax on
     interest paid on the Loan Notes. Individual shareholders whose total income
     does not exceed the threshold for higher rate tax will generally be
     chargeable to UK income tax on such interest at the lower rate (currently
     20 per cent.). Credit will be available against UK income or corporation
     tax for any United States tax required to be deducted or withheld from the
     interest, provided that such credit will not exceed the credit which would
     have been allowed had all reasonable steps been taken (including any claims
     which could be made by the holder under the terms of the double taxation
     agreement between the United States and the United Kingdom) to minimise
     such United States tax.

     On a transfer of Loan Notes by an individual, a charge to UK income tax may
     arise under the "accrued income scheme" in respect of the interest on the
     Loan Notes which has accrued since the preceding interest payment.

     A holder of Loan Notes which is a company within the charge to UK
     corporation tax in respect of the Loan Notes will generally bring into the
     charge to tax as income interest on, and any profits and gains arising
     from, the Loan Notes in each accounting period broadly in accordance with
     the holder's authorised accounting treatment for this purpose.

     Persons paying or receiving interest on or after 6 April 2001 may be
     required to provide certain information to the Inland Revenue, which could
     include the name and address of the person beneficially entitled to the
     interest.

(E) LASMO SHARE OPTION SCHEMES

     Special tax provisions may apply to LASMO Shareholders who acquire new
     LASMO Shares by exercising options under the LASMO Share Option Schemes,
     including provisions imposing a charge to income tax when such an option is
     exercised.

                                      VI-29
<PAGE>   171

(F) STAMP DUTY AND STAMP DUTY RESERVE TAX

     No stamp duty or stamp duty reserve tax will be payable by LASMO
     Shareholders in connection with acceptance of the Offer and/or the Loan
     Note Alternative.

     Any instrument effecting the disposition of an Amerada Hess Share might not
     be admissible in evidence in any court proceedings in the United Kingdom
     unless duly stamped.

     No stamp duty or stamp duty reserve tax should be payable on the issue,
     transfer or redemption of the Loan Notes.

     The above statements are intended only as a general guide to the current
     position. Special rules, imposing charges to stamp duty and/or stamp duty
     reserve tax, may apply to the issue or transfer of shares to particular
     categories of person, in particular to persons whose business is or
     includes the provision of clearance services or the issuance of depositary
     receipts, or nominees or agents of such persons.

15. UNITED STATES FEDERAL INCOME TAXATION

The following is a summary of the principal US federal income tax consequences
that may be relevant with respect to the exchange of LASMO Shares or LASMO ADSs
for Amerada Hess Shares, Loan Notes and/or cash pursuant to the Offer and the
ownership and disposition of Amerada Hess Shares, Loan Notes and/or cash
acquired under the Offer. For purposes of this summary, a "US holder" is a
beneficial owner of LASMO Shares, or LASMO ADSs, as the case may be, that, for
US federal income tax purposes, is: (i) a citizen or resident of the United
States, (ii) a partnership or corporation created or organized in or under the
laws of the United States or any State thereof (including the District of
Columbia), (iii) an estate the income of which is subject to US federal income
taxation regardless of its source or (iv) a trust if such trust validly elects
to be treated as a United States person for US federal income tax purposes or if
(x) a court within the United States is able to exercise primary supervision
over its administration and (y) one or more United States persons have the
authority to control all of the substantial decisions of such trust. A "Non-US
holder" is a beneficial owner of LASMO Shares, LASMO ADSs, Amerada Hess shares,
or Loan Notes, as the case may be, that is not a US holder.

This summary does not contain a comprehensive description of all of the tax
consequences of the exchange of LASMO Shares or LASMO ADSs for Amerada Hess
Shares, Loan Notes and/or cash pursuant to the Offer and the ownership and
disposition of Amerada Hess Shares, Loan Notes and/or cash. In particular, this
description applies only to holders who hold LASMO Shares or LASMO ADSs, as the
case may be, and will hold Amerada Hess Shares or Loan Notes, as the case may
be, as capital assets at all relevant times. This summary does not address tax
considerations applicable to holders that may be subject to special tax rules,
such as financial institutions, insurance companies, real estate investment
trusts, regulated investment companies, grantor trusts, dealers or traders in
securities or currencies, tax-exempt entities, persons that will hold Amerada
Hess Shares or Loan Notes as part of an "integrated", "hedging" or "conversion"
transaction or as a position in a "straddle" for US federal income tax purposes,
persons that have a "functional currency" other than the United States dollar or
holders that own (or are deemed to own) 10 per cent. or more (by voting power or
value) of the stock of LASMO or Amerada Hess. Moreover, this summary does not
address the US federal estate and gift or alternative minimum tax consequences
of the exchange of LASMO Shares or LASMO ADSs for Amerada Hess Shares, Loan
Notes and/or cash pursuant to the Offer and the ownership and disposition of
Amerada Hess Shares or Loan Notes.

This summary is based on the Internal Revenue Code of 1986, as amended (the
"Code"), United States Treasury Regulations and judicial and administrative
interpretations thereof, in each case as in effect and available on the date of
this document. All of the foregoing are subject to change, which change could
apply retroactively and could affect the tax consequences described below.

Each holder of LASMO Shares or LASMO ADSs should consult its own tax advisor
with respect to the US federal, state, local and foreign tax consequences of the
exchange of LASMO Shares or LASMO ADSs for Amerada Hess Shares, Loan Notes
and/or cash pursuant to the Offer and the ownership and disposition of Amerada
Hess Shares and Loan Notes.

                                      VI-30
<PAGE>   172

(A) CONSEQUENCES OF THE EXCHANGE PURSUANT TO THE OFFER

     (i)    US Holders

        Generally, a US holder will recognize gain or loss upon the receipt of
        Amerada Hess Shares and cash in exchange for such holder's LASMO Shares
        or LASMO ADSs pursuant to the Offer in an amount equal to the difference
        between (a) the sum of (i) the fair market value of such Amerada Hess
        Shares received and (ii) the US Dollar value of the pounds sterling that
        would have been received on the date of receipt and (b) the US holder's
        adjusted tax basis in the LASMO Shares or LASMO ADSs, as the case may
        be. Such gain or loss will be capital gain or loss. In the case of a
        noncorporate US holder, the maximum marginal US federal income tax rate
        applicable to such gain will be lower than the maximum marginal US
        federal income tax rate applicable to ordinary income if such US
        holder's holding period for such LASMO Shares or LASMO ADSs exceeds one
        year. Gain or loss, if any, recognized by a US holder generally will be
        treated as US source income or loss for US foreign tax credit purposes.
        The deductibility of capital losses is subject to limitations. A US
        holder's initial tax basis in the Amerada Hess Shares will be the fair
        market values of such Amerada Hess Shares on the date such Amerada Hess
        Shares are received.

     (ii)   Non-US Holders

        Subject to the discussion below under "Backup Withholding Tax and
        Information Reporting Requirements," a Non-US holder generally will not
        recognize gain or loss upon the receipt of Amerada Hess Shares, Loan
        Notes and/or cash in exchange for such holder's LASMO Shares or LASMO
        ADSs pursuant to the Offer unless (i) such gain is effectively connected
        with the conduct by such Non-US holder of a trade or business in the
        United States (in which case the branch profits are described under
        "Distributions" below may also apply if the holder is a foreign
        corporation) or (ii) in the case of any gain realized by an individual
        Non-US holder, such holder is present in the United States for 183 days
        or more in the taxable year of such sale or exchange and certain other
        conditions are met.

(B) AMERADA HESS SHARES

     (i)    DISTRIBUTIONS.  The gross amount of any distribution with respect to
        Amerada Hess Shares, other than a distribution of Amerada Hess Shares
        made to all shareholders, will be includible in a US holder's ordinary
        income as dividends to the extent of Amerada Hess' current and
        accumulated earnings and profits (as determined under US federal income
        tax principles). Corporate US holders generally will be eligible for the
        dividends received deduction. The dividends received deduction is
        subject to certain limitations, though, and the benefit of such
        deduction may be reduced by the corporate alternative minimum tax.
        Accordingly, corporate US holders should consult their own tax advisors
        regarding the availability of, and limitations on, the dividends
        received deduction. Any distributions in excess of Amerada Hess' current
        and accumulated earnings and profits will be treated first as a tax-free
        return of capital to the extent of a US holder's adjusted tax basis and
        thereafter as capital gain.

        Dividends paid to a Non-US holder generally will be subject to
        withholding of US federal income tax at a rate of 30 per cent. unless
        such rate is reduced by an applicable US income tax treaty. Currently,
        dividends paid to an address in a foreign country generally are presumed
        to be paid to a resident of such country in determining the
        applicability of a US income tax treaty. However, US Treasury
        Regulations issued on October 6, 1997, as amended (the "New Treasury
        Regulations"), would, for dividends paid after December 31, 2000,
        require a Non-US holder to file certain forms (i.e., IRS Form W-8BEN) to
        obtain the benefit of any applicable US income tax treaty. Non-US
        holders are urged to consult their own tax advisors concerning the
        effect, if any, of the New Treasury Regulations. Further, except as
        otherwise provided in an applicable US income tax treaty, a Non-US
        holder will be taxed at ordinary US federal income tax rates (on a net
        income basis) on dividends that are effectively connected with the
        conduct of a trade or business by such Non-US holder within the United
        States, but such dividends (assuming applicable procedural requirements
        are met) will not be subject to US withholding tax as described above.
        If such Non-US holder is a foreign corporation, it may also be subject
        to a 30 per cent. branch profits tax unless it qualifies for a lower
        rate under an applicable US income tax treaty.

                                      VI-31
<PAGE>   173

     (ii)   SALE OR EXCHANGE OF AMERADA HESS SHARES.  Generally, upon the sale
        or exchange of Amerada Hess Shares, a US holder will recognize gain or
        loss equal to the difference between the amount realized on the sale or
        exchange and its adjusted tax basis in such Amerada Hess Shares. For
        non-corporate US holders, the maximum US federal income tax rate
        applicable to such gain will be lower than the maximum US federal income
        tax rate applicable to ordinary income if such US holder's holding
        period for such Amerada Hess Shares exceeds one year.

        Subject to the discussion below under "Backup Withholding Tax and
        Information Reporting Requirements," a Non-US holder generally will not
        be subject to US federal income tax in respect of gain recognized on the
        sale or exchange of Amerada Hess Shares unless (i) such gain is
        effectively connected with the conduct by such Non-US holder of a trade
        or business in the United States (in which case the branch profits tax
        described under "Distributions" above may also apply of the holder is a
        foreign corporation), (ii) in the case of any gain realized by an
        individual Non-US holder, such holder is present in the United States
        for 183 days or more in the taxable year of such sale or exchange and
        certain other conditions are met, or (iii) Amerada Hess is or has been a
        "United States real property holding corporation" for US federal income
        tax purposes and, in the event that the Amerada Hess Shares are
        considered to be "regularly traded," the Non-US holder held, directly or
        indirectly, at any time during the five-year period ending on the date
        of such sale or exchange more than five per cent. of the Amerada Hess
        Shares. Amerada Hess believes that it is not currently (and is not
        likely to become) a United States real property holding corporation.
        Generally, the rule for stock in a United States real property holding
        corporation takes precedence over relief provided by US income tax
        treaties.

     (iii)  UNITED STATES FEDERAL ESTATE TAX.  Amerada Hess Shares that are
        owned, or treated as being owned, at the time of death of a Non-US
        holder who is not a citizen or resident (as defined for US federal
        estate tax purposes) of the United States will be includable in such
        holder's gross estate for US federal estate tax purposes, unless an
        applicable US estate tax treaty provides otherwise.

(C) LOAN NOTES

Subject to the discussion of backup withholding tax below, under current United
States federal income and estate tax law:

     (i)    payments of principal of, and interest on, any Loan Note to a Non-US
        holder or foreign fiduciary will not be subject to withholding of US
        federal income tax; provided that with respect to payments of interest
        (including original issue discount, if any), the Non-US holder is not
        (x) a "controlled foreign corporation" (as such term is defined in the
        Code) which is related to Amerada Hess through stock ownership and (y) a
        person owning (actually or constructively) securities representing at
        least 10 per cent. of the total combined outstanding voting power of all
        classes of voting stock of Amerada Hess;

     (ii)   a Non-US holder will not be subject to US federal income or
        withholding tax on gain recognized on the sale, exchange or redemption
        of a Loan Note unless (aa) such gain is effectively connected with the
        conduct by such Non-US holder of a trade or business in the United
        States (in which case the branch profits tax described under
        "Distributions" above may also apply if the holder is a foreign
        corporation), (bb) in the case of any gain realized by an individual
        Non-US holder, such holder is present in the United States for 183 days
        or more in the taxable year of such sale or exchange and certain other
        conditions are met; and

     (iii)  a Loan Note will not be subject to United States federal estate tax
        as a result of the death of a holder who is not a citizen or resident of
        the United States; provided that at the time of death (aa) such holder
        did not actually or constructively own 10 per cent. or more of the
        combined voting power of all classes of stock of Amerada Hess and (bb)
        payments of interest on such Loan Note would not have been effectively
        connected with the conduct by such holder of a trade or business within
        the United States.

                                      VI-32
<PAGE>   174

(D) BACKUP WITHHOLDING TAX AND INFORMATION REPORTING REQUIREMENTS

US backup withholding tax and information reporting requirements generally apply
to certain payments to certain noncorporate holders of securities. Information
reporting generally will apply to payments of: (i) dividends on Amerada Hess
Shares, (ii) payments of principal and interest on Loan Notes, and (iii)
proceeds from the sale or redemption of Amerada Hess Shares by a payor within
the United States to a holder thereof (other than an "exempt recipient,"
including a corporation, a payee that is not a United States person that
provides an appropriate certification and certain other persons). A payor within
the United States will be required to withhold 31 per cent. of any payments of
the proceeds from the sale or redemption of Amerada Hess Shares or Loan Notes
within the United States to a holder (other than an "exempt recipient") if such
holder fails to furnish its correct taxpayer identification number or otherwise
fails to comply with such backup withholding tax requirements. However,
dividends paid to a Non-US holder outside the United States that are subject to
the 30 per cent. or US income tax treaty-reduced rate of withholding tax
generally will be exempt from backup withholding tax.

Further, US information reporting and backup withholding tax will not apply to
payments on a Loan Note made outside the United States or dividends paid outside
the United States to the beneficial owner of a Loan Note or Amerada Hess Shares,
as the case may be, that is not a United States person; provided neither Amerada
Hess nor the paying agent has actual knowledge that the holder is a United
States person for information reporting and backup withholding tax purposes. In
addition, information reporting requirements and backup withholding tax will not
apply to any payment on a Note or any payment of dividends outside the United
States by a foreign office of a foreign custodian, foreign nominee or other
foreign agent of the beneficial owner of such Loan Note or Amerada Hess Shares,
as the case may be; provided that such custodian, nominee or agent (i) derives
less than 50 per cent. of its gross income for certain time periods from the
conduct of a trade or business in the United States and (ii) is not a
"controlled foreign corporation" for US federal income tax purposes. Payments on
a Loan Note or payments of dividends outside the United States to the beneficial
owner thereof by a foreign office of any other custodian, nominee or agent will
not be subject to backup withholding tax and information reporting unless such
custodian, nominee or agent has documentary evidence in its records that the
beneficial owner is not a United States person for purposes of such backup
withholding tax and information reporting requirements and certain other
conditions are met, or the beneficial owner otherwise establishes an exemption.
Payments on a Note or payments of dividends by the United States office of a
custodian, nominee or other agent of the beneficial owner of such Loan Note or
Amerada Hess Shares, as the case may be, will be subject to information
reporting and backup withholding tax unless the beneficial owner certifies its
non-United States person status under penalty of perjury or otherwise
establishes an exemption.

Information reporting and backup withholding tax will not apply to any payment
of the proceeds of a sale of a Loan Note or Amerada Hess Shares, as the case may
be, made outside the United States by a foreign office of a foreign "broker;"
provided that such broker (i) derives less than 50 per cent. of its gross income
for certain time periods form the conduct of a trade or business in the United
States and (ii) is not a "controlled foreign corporation" for United States
federal income tax purposes. Payments of the proceeds of a sale of a Loan Note
or Amerada Hess Shares, as the case may be, effected outside the United States
by a foreign office of any other broker will not be subject to backup
withholding tax and information reporting unless such broker has documentary
evidence in its records that the beneficial owner is not a United States person
for purposes of such backup withholding tax and information reporting
requirements and certain other conditions are met, or the beneficial owner
otherwise establishes an exemption. Payments of the proceeds of a sale of a Loan
Note or Amerada Hess Shares, as the case may be, by the United States office of
a custodian, nominee or other agent of the beneficial owner of such Loan Note
will be subject to information reporting and backup withholding tax unless the
beneficial owner certifies its non-United States person status under penalty of
perjury or otherwise establishes an exemption.

The New Regulations would modify certain of the rules discussed above generally
with respect to payments on Amerada Hess Shares or Loan Notes made after 31
December 2000. In particular, a payor within the United States will be required
to withhold 31 per cent. of any payments of dividends on Amerada Hess Shares,
interest on Loan Notes, or proceeds from the sale of Amerada Hess Shares or Loan
Notes within the United States to a holder (other than an exempt recipient such
as a corporation or a payee that is not a United States person and that provides
an appropriate certification) if such holder fails to furnish its correct
taxpayer identification number or otherwise fails to comply with, or establish
an exemption from, such backup withholding tax requirements. In the case of such
payments by a payor or
                                      VI-33

middleman within the United States to a foreign simple trust, a foreign grantor
trust or a foreign partnership (other than payments to a foreign simple trust, a
foreign grantor trust or a foreign partnership that qualifies as a "withholding
foreign trust" or a "withholding foreign partnership" within the meaning of such
United States Treasury Regulations and payments to a foreign simple trust, a
foreign grantor trust or a foreign partnership that are effectively connected
with the conduct of a trade or business in the United States), the beneficiaries
of the foreign simple trust, the persons treated as the owners of the foreign
grantor trust or the partners of the foreign partnership, as the case may be,
will be required to provide the certification discussed above in order to
establish an exemption from backup withholding tax and information reporting
requirements. Moreover, a payor or middleman may rely on a certification
provided by a payee that is not a United States person only if such payor or
middleman does not have actual knowledge or a reason to know that any
information or certification stated in such certificate is incorrect.

17. SOURCES OF INFORMATION AND BASIS OF CALCULATION

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

(a) The market value of an Amerada Hess Share is based on the NYSE closing price
     of $62 13/16 on 3 November 2000, the last NYSE dealing day prior to the
     date of the Press Announcement.

(b) 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

                                      VI-34
<PAGE>   176

     which in LASMO's opinion it is reasonable to expect may be issued in the
     relevant period pursuant to the exercise of options.

(c)  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 Price of a LASMO Share on that date.

(d) The premium of the offer value per LASMO Share over the average Closing
     Price of a LASMO Share over the 6 months preceding the Press Announcement
     is based on the average of the Closing Prices on each London Stock Exchange
     dealing day over the 6 months immediately preceding (and including) 3
     November 2000.

(e) All currency conversions between pounds sterling and US dollars have been
     made at an exchange rate of US$1.4484: L1.00, 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).

                                  APPENDIX VII

                 DESCRIPTION OF AMERADA HESS SHARES AND CHANGES
                     IN THE RIGHTS OF LASMO SECURITYHOLDERS

1.  DESCRIPTION OF AMERADA HESS SHARES

As of 31 October 2000, 88,097,505 Amerada Hess Shares and 326,805 shares of
$1.50 Cumulative Convertible Preferred Stock were outstanding, out of a total
authorised share capital of 220,000,000 shares consisting of 200,000,000 of
Amerada Hess Shares and 20,000,000 shares of $1.50 Cumulative Convertible
Preferred Stock. All outstanding Amerada Hess Shares are fully paid and
non-assessable.

The following is a brief description of certain rights of holders of Amerada
Hess Shares. For a complete understanding of these rights, LASMO Securityholders
are referred to the laws and applicable regulations of the State of Delaware,
United States, the listing requirements of the NYSE and the restated certificate
of incorporation of Amerada Hess.

(a) General

     Amerada Hess is incorporated in the State of Delaware, United States and
     operates in accordance with the DGCL. The rights of Amerada Hess
     stockholders are determined by the DGCL, the securities and other
     legislation of the United States, Amerada Hess' restated certificate of
     incorporation and Amerada Hess' by-laws. The Amerada Hess Shares are traded
     on the NYSE.

(b) Certificates

     Amerada Hess Shares are issued in registered form. Every holder of Amerada
     Hess Shares is entitled to a share certificate.

(c)  Dividends

     Holders of Amerada Hess Shares are entitled, subject to the prior rights,
     if any, of holders of shares of any series of preferred stock that the
     Board of Directors may establish, to such dividends as may be declared by
     the board of directors of Amerada Hess out of funds legally available for
     this purpose.

     Under the terms of the most restrictive agreements pursuant to which
     indebtedness of Amerada Hess has been incurred, at 30 September 2000
     Amerada Hess had $1,253,123,000 of retained earnings free of restrictions
     relating to dividends.

(d) Meetings

     Annual meetings of the Amerada Hess stockholders are held on the date
     designated by the by-laws of Amerada Hess. Written notice must be mailed to
     each stockholder entitled to vote not less than ten nor more than 60 days
     before the date of the meeting. The presence in person or by proxy of the
     holders of record of a majority of the issued and outstanding shares of
     Amerada Hess entitled to vote at such meeting constitutes a quorum for the
     transaction of business at meetings of the stockholders. Special meetings
     of the stockholders may be called for any purpose by the board of directors
     and shall be called by the chairman of the board or the secretary upon the
     written request, stating the purpose of such meeting, of the holders of a
     majority of the outstanding shares of all classes of capital stock entitled
     to vote at the meeting.

(e) Voting rights

     The holders of Amerada Hess Shares are entitled to one vote for each share
     held on record. Holders of Amerada Hess Shares may vote by proxy. Except as
     may be otherwise provided by applicable law, the restated certificate of
     incorporation or the by-laws of Amerada Hess, all elections shall be had
     and all questions decided by a plurality of the votes cast by stockholders
     entitled to vote thereon at a duly held meeting of stockholders at which a
     quorum is present.

(f)  Liquidation, dissolution or winding-up

     In the event of a liquidation, dissolution or winding-up of Amerada Hess,
     the holders of Amerada Hess Shares are entitled to share rateably according
     to the number of shares held by them in all
                                      VII-1
<PAGE>   184

     remaining assets available for distribution to the holders of Amerada Hess
     Shares after discharge of outstanding liabilities and payment of such
     liquidation preference, if any, of any series of preferred stock that the
     Amerada Hess board of directors may establish.

(g) Transfers

     The Amerada Hess by-laws do not allow the board of directors to refuse to
     register transfers of shares. Registration is conditional upon surrender of
     share certificates in respect of Amerada Hess Shares, AHC shares or, if
     lost, furnishing an affidavit and indemnity in lieu thereof.

(h) Takeover Provisions

     Certain provisions of the restated certificate of incorporation and by-laws
     of Amerada Hess may have the effect of delaying, deferring or preventing a
     change of control of Amerada Hess in connection with certain extraordinary
     corporate transactions. An article of the restated certificate of
     incorporation requires that business combinations, which term is defined to
     include certain mergers, asset sales, security issuances, recapitalisations
     and liquidations, involving Amerada Hess or any of its subsidiaries and
     certain acquiring persons (namely, a person, entity or specified group
     which beneficially owns or controls at least 20 per cent. of the voting
     stock of Amerada Hess) be approved by the holders of two-thirds of Amerada
     Hess' voting stock (not including shares held by an acquiring person with
     which or by or on whose behalf a business combination is proposed) unless
     such business combination either: (i) has been authorised by the board of
     directors prior to the time that the acquiring person involved in such
     business combination became an acquiring person, or (ii) will result in the
     receipt by the other stockholders of a specified minimum amount and form of
     payment for their shares.

     The restated certificate of incorporation and the by-laws of Amerada Hess
     also provide for a board of directors divided as nearly equal as possible
     into three classes. In addition, the restated certificate of incorporation
     and the by-laws require (i) approval of holders of 80 per cent. of the
     voting stock to remove directors or to amend, alter or repeal the
     provisions as to the classified board and other related provisions, (ii)
     advance notice of, and a specified procedure for, shareholder nominations
     for director, (iii) the taking of stockholder action only at annual or
     special meetings (to be called only by the chairman of the board, the
     President or a majority of the board of directors) and prohibiting
     stockholder action by written consent, and (iv) the filling of vacancies on
     the board by remaining directors, though less than a quorum. Such
     provisions of the restated certificate of incorporation and the by-laws may
     make it more difficult for a person or entity to acquire and exercise
     control of the company and remove incumbent directors and officers.

(i)  Delaware Anti-Takeover Law

     Amerada Hess is subject to the provisions of Section 203 of the DGCL. In
     general, the law prohibits a public Delaware corporation from engaging in a
     "business combination" with an "interested stockholder" for a period of
     three years after the date of the transaction in which the person became an
     interested stockholder, unless (i) the corporation has elected in its
     certificate of incorporation not to be governed by Section 203 (Amerada
     Hess has not made such an election), (ii) the business combination was
     approved by the board of directors of the corporation before the other
     party to the business combination became an "interested stockholder", (iii)
     upon consummation of the transaction that made it an "interested
     stockholder", the "interested stockholder" owned at least 85 per cent. of
     the voting stock of the corporation outstanding at the commencement of the
     transaction (excluding voting stock held by directors who are also officers
     or held in employee benefit plans in which employees do not have a
     confidential right to tender or vote stock held by the plan) or (iv) the
     business combination was approved by the board of directors of the
     corporation and ratified by at least two-thirds of the voting stock which
     the "interested stockholder" did not own. The three year prohibition also
     does not apply to certain business combinations proposed by the "interested
     stockholder" during the previous three years or who becomes an "interested
     stockholder" with the approval of a majority of the corporation's
     directors.

     "Business combination" is defined generally to include mergers or
     consolidations between a Delaware corporation and an "interested
     stockholder", transactions with an "interested stockholder" involving the
     assets or stock of the corporation or its majority owned subsidiaries and
     transactions which increase an "interested stockholder's" percentage
     ownership of the stock. An

                                      VII-2
<PAGE>   185

     "INTERESTED STOCKHOLDER" is defined as a person who, together with
     affiliates and associates, owns (or within the prior three years, did own)
     15 per cent. or more of a corporation's voting stock. The application of
     Section 203 may also have the effect of delaying, deferring or preventing a
     change of control of the Amerada Hess.

(j)  Other rights

     Holders of Amerada Hess Shares have no pre-emption, redemption, conversion
     or other subscription rights.

(k)  Registrar and Transfer Agents

     The Registrar for the Amerada Hess Shares is Manufacturers Hanover Trust
     Company in New York, New York, and the transfer agents for the Amerada Hess
     Shares are Manufacturers Hanover Trust Company, First Fidelity Bank, N.A.
     (in Newark, New Jersey) and Royal Trust Company (in Montreal, Quebec and in
     Toronto, Ontario).

2.  DIFFERENCES BETWEEN AMERADA HESS SHARES AND LASMO SHARES

The following is a summary comparison of material differences between the rights
of an Amerada Hess stockholder and a LASMO Shareholder arising from the
differences between the corporate laws of Delaware and of England and Wales, the
governing instruments of the two companies, and the securities laws and
regulations governing the two companies. However, it is not intended to be a
complete description of the laws of Delaware or of England and Wales, nor of the
other rules or laws referred to in this summary. For information as to where the
governing instruments of Amerada Hess and LASMO may be obtained, see paragraph 1
of Appendix III and paragraph 1 of Appendix IV, respectively. You are encouraged
to obtain and read these documents.

VOTING RIGHTS

(i)  Amerada Hess Stockholders

     Under Delaware law, unless the certificate of incorporation provides
     otherwise, each stockholder is entitled to one vote for each share of
     capital stock held by the stockholder.

     Except as described herein, the certificate of incorporation of Amerada
     Hess does not alter the voting rights as provided under Delaware law.

     Under Delaware law, a certificate of incorporation may provide that in
     elections of directors and other specified circumstances, stockholders are
     entitled to cumulative voting.

     The certificate of incorporation of Amerada Hess does not provide for
     cumulative voting.

(ii)  LASMO Shareholders

     Under English law, unless the articles of association provide otherwise, a
     shareholder entitled to vote at a shareholders' meeting is entitled to one
     vote on a show of hands regardless of the number of shares he or she holds;
     provided, however, that any group of five ordinary shareholders (or a
     lesser number if provided in the articles of association) and any
     shareholder representing at least ten per cent of the total voting rights
     (or a lower percentage if provided in the articles of association) has the
     statutory right to demand a vote by a poll, which means that each ordinary
     shareholder would be entitled to one vote for each ordinary share held by
     the shareholder. The articles of association of LASMO provide that two
     shareholders present in person or by proxy and entitled to vote may demand
     a poll.

     Under English law, ordinary resolutions are decided on a show of hands and
     must be approved by at least a majority of the shareholders present in
     person, or by proxy if the memorandum and articles of association so
     permit, and voting at a meeting. If a poll is demanded, the resolution
     conducted on a poll must be approved by holders of at least a majority of
     the votes cast at the meeting. Both special and extraordinary resolutions
     require the affirmative vote of at least 75 per cent of the votes cast at
     the meeting.

     Under English law, two shareholders present in person constitute a quorum
     for purposes of a general meeting, unless the company's articles of
     association specify otherwise. LASMO's articles

                                      VII-3
<PAGE>   186

     of association specify a quorum of three shareholders, present in person or
     by proxy and entitled to vote.

     Under English law, the voting rights of shareholders are regulated by a
     company's articles of association. LASMO's articles of association provide
     that every shareholder present at a general meeting shall have one vote on
     a show of hands. On a poll, every member who is present in person or by
     proxy shall have one vote for every 25p nominal amount of ordinary share
     capital of which he is the holder.

ACTION BY WRITTEN CONSENT

(i)  Amerada Hess Stockholders

     Under Delaware law, unless otherwise provided in the certificate of
     incorporation, stockholders may take any action required or permitted to be
     taken at a stockholders' meeting without a meeting if consented to in
     writing by the same number of votes that would be required if the action
     were to be taken at a meeting.

     The Amerada Hess certificate of incorporation prohibits stockholder action
     by written consent.

(ii)  LASMO Shareholders

     Under English law, unless the company's articles of association provide
     otherwise, the consent in writing of all shareholders is required in order
     to approve, without a meeting, a matter requiring shareholder approval.
     LASMO's articles of association do not provide otherwise.

SHAREHOLDERS PROPOSALS AND SHAREHOLDER NOMINATIONS OF DIRECTORS

(i)  Amerada Hess Stockholders

     See "Special meetings of shareholders".

(ii)  LASMO Shareholders

     Under English law, shareholders may demand that a resolution be voted on at
     a general meeting if the demand is made:

     (1)   by shareholders holding at least five per cent of the total voting
        rights at the meeting to which the requisition relates; or

     (2)   by at least 100 shareholders holding shares on which there has been
        paid an average sum per shareholder of at least L100.

     The shareholders must deposit the demand at the company's registered office
     at least six weeks before the general meeting to which it relates.

     In general, resolutions to appoint directors must be put to shareholders on
     the basis of one resolution for each nominated director. A resolution
     including more than one director may be presented to be voted upon at a
     general meeting only if the shareholders have first unanimously approved so
     doing.

SOURCES AND PAYMENT OF DIVIDENDS

(i)  Amerada Hess Stockholders

     Under Delaware law, the board of directors, subject to any restrictions in
     the corporation's certificate of incorporation, may declare and pay
     dividends out of:

     (1)   surplus of the corporation, which is defined as net assets less
        statutory capital; or

     (2)   if no surplus exists, out of the net profits of the corporation for
        the fiscal year in which the dividend is declared and/or the preceding
        fiscal year;

     provided, however, that if the capital of the corporation has been
     diminished to an amount less than the aggregate amount of capital
     represented by the issued and outstanding stock of all classes having
     preference upon the distribution of assets, the board may not declare and
     pay dividends out of the corporation's net profits until the deficiency in
     the capital has been repaired.

                                      VII-4
<PAGE>   187

(ii)  LASMO Shareholders

     Subject to the prior rights of holders of preferred shares, an English
     company may pay dividends on its ordinary shares only out of its
     distributable profits, defined as accumulated, realized profits less
     accumulated, realized losses, and not out of share capital, which includes
     share premiums, which are equal to the excess of the consideration for the
     issue of shares over the aggregate nominal amount of such shares. Amounts
     credited to the share premium account, however, may be used to pay up
     unissued shares which may then be distributed to shareholders in proportion
     to their holdings.

     In addition, under English law, LASMO will not be permitted to make a
     distribution if, at the time, the amount of its net assets is less than the
     aggregate of its issued and paid-up share capital and undistributable
     reserves.

RIGHTS OF PURCHASE AND REDEMPTION

(i)  Amerada Hess Stockholders

     Under Delaware law, any corporation may purchase, redeem and dispose of its
     own shares, except that it may not purchase or redeem these shares if the
     capital of the corporation is impaired at the time or would become impaired
     as a result of the redemption, provided that if a corporation redeems its
     stock, immediately following any such redemption, the corporation must have
     outstanding one or more shares of one or more classes which shares together
     must have full voting power.

     However, at any time, a corporation may purchase or redeem any of its
     shares which are entitled upon any distribution of assets to a preference
     over another class of its stock if these shares will be retired upon
     acquisition or redemption, thereby reducing the capital of the corporation.

     The NYSE requires that prompt publicity be given and prompt notice be sent
     to the NYSE of action which will result in, or which looks toward, either
     the partial or full call for redemption of a listed security. NYSE rules
     provide that when a listed security is fully redeemed, trading is suspended
     as soon as the redemption funds become available to the holders of the
     security. When only a part of the listed securities are redeemed, the
     amount authorised to be listed is reduced by the amount redeemed as soon as
     the redemption funds become available to holders of the redeemed
     securities.

(ii)  LASMO Shareholders

     Under English law, a company may issue redeemable shares if authorised by
     its memorandum and articles of association, subject to any conditions
     stated therein.

     A company may purchase its own shares, including any redeemable shares, if
     the purchase:

     (1)   is authorised by its memorandum and articles of association; and

     (2)   (a)   in the case of an open-market purchase, authority to make the
             market purchase has been given by any ordinary resolution of its
             shareholders; or

        (b)   in all other cases, has been approved by a special resolution.

     A company may redeem or repurchase shares only if the shares are fully paid
     and, in the case of public companies, only out of:

     (1)   distributable profits; or

     (2)   the proceeds of a new issue of shares, made for the purpose of the
        repurchase or redemption.

     The London Stock Exchange requires that where a company has issued shares
     which are listed on the London Stock Exchange and are convertible into a
     class of shares to be repurchased, the holders of the convertible shares
     must first pass an extraordinary resolution approving any repurchase at a
     separate class meeting.

     The London Stock Exchange requires that purchases within a 12-month period
     of 15 per cent. or more of a company's share capital must be made through
     either a tender or partial offer to all shareholders, at a stated maximum
     or fixed price.

                                      VII-5
<PAGE>   188

     Purchases within a 12-month period below the 15 per cent. threshold may be
     made through:

     (1)   the open market, provided that the price is not more than five per
        cent. above the average of the middle-market quotations taken from the
        Official List for the five trading days before the purchase date; or

     (2)   an off-market transaction negotiated with one or more shareholders
        subject to prior approval of the transaction by special resolution.

     LASMO's articles of association authorise the issue of redeemable shares,
     subject to the Companies Act and with the sanction of a special resolution,
     and the purchase of its own shares, subject to and in accordance with the
     Companies Act and to any rights conferred on the holders of any class of
     Shares.

GENERAL MEETINGS OF SHAREHOLDERS

(i)  Amerada Hess Stockholders

     The by-laws of Amerada Hess provide that the annual meeting of stockholders
     shall be held on a date and at a time fixed by the board of directors.
     Under Delaware law the board of directors may also determine the place of
     such meeting either within or without of the State of Delaware or may
     determine that such meeting shall not be held at any place and instead be
     held by means of remote communication.

(ii)  LASMO Shareholders

     LASMO's articles of association provide that annual general meetings shall
     be held at such time and place as the board of directors may determine,
     subject to the provisions of the Companies Act which require an annual
     general meeting to be held in each year and not more than 15 months to
     elapse between the date of one annual general meeting of a company and that
     of the next.

SPECIAL MEETINGS OF SHAREHOLDERS

(i)  Amerada Hess Stockholders

     Delaware law provides that special meetings of stockholders may be called
     by:

     (1)   the board of directors; or

     (2)   any person or persons authorised by the corporation's certificate of
        incorporation or by-laws.

     The by-laws of Amerada Hess provide that special meetings of the holders of
     any class or of all classes of Amerada Hess' capital stock may be called at
     any time by the board of directors, and shall be called only by the
     chairman of the board or the President, and shall be called by the
     Secretary at the request of the Board of Directors pursuant to a resolution
     approved by a majority of the entire Board of Directors.

     The Amerada Hess by-laws provide that written notice of each meeting of the
     stockholders, stating the date, hour, place and purpose or purposes
     thereof, shall be given, personally or by mail, to each stockholder
     entitled to vote at the meeting not less than ten or more than 60 days
     before the date of the meeting, except that notice of any special meeting
     shall be delivered or mailed not less than ten days before such meeting. If
     mailed, such notice shall be deposited in the US mail, postage prepaid,
     directed to the stockholder at his/her address as it appears on the records
     of Amerada Hess.

(ii)  LASMO Shareholders

     Under English law, an extraordinary general meeting of shareholders may be
     called by:

     (1)   the board of directors; or

     (2)   shareholders holding at least one-tenth of the paid-up capital of the
        company carrying voting rights at general meetings.

                                      VII-6
<PAGE>   189

     The notice requirements for an ordinary resolution, an extraordinary
     resolution and a special resolution are as follows:

     (1)   ordinary resolution -- 14 days' notice;

     (2)   extraordinary resolution -- 14 days' notice; and

     (3)   special resolution -- 21 days' notice.

     Notwithstanding the foregoing notice requirements, 21 days' notice must be
     given for an annual general meeting and any resolutions to be proposed
     thereat.

     LASMO's articles of association require 21 days' notice for a resolution
     appointing a director.

     In addition, general meetings may be called upon shorter notice if:

     (1)   in the case of an annual general meeting, all the shareholders who
        are permitted to attend and vote agree to the shorter notice; or

     (2)   in the case of an extraordinary general meeting, a majority of the
        shareholders holding at least 95 per cent by nominal value of the shares
        which can be voted at the meeting so agree.

     LASMO's articles of association state that any notice shall be exclusive of
     the day on which it is served, or deemed to be served, and of the day for
     which it is given.

     "Extraordinary resolutions" are relatively unusual and are confined to
     matters out of the ordinary course of business, such as a proposal to wind
     up the affairs of the company.

     "Special resolutions" generally involve proposals to:

     (1)   change the name of the company;

     (2)   alter its capital structure;

     (3)   change or amend the rights of shareholders;

     (4)   permit the company to issue new shares for cash without applying the
        shareholders' preemptive rights,

     (5)   amend the company's objects, or purpose, clause in its memorandum of
        association;

     (6)   amend the company's articles of association; or

     (7)   carry out other matters for which the company's articles of
        association or the Companies Act prescribe that a "special resolution"
        is required.

     All other proposals relating to the ordinary course of the company's
     business, such as the election of directors and transactions such as
     mergers, acquisitions and dispositions, are the subject of an "ordinary
     resolution".

APPRAISAL RIGHTS

(i)  Amerada Hess Stockholders

     Delaware law provides stockholders of a corporation involved in a merger
     the right to demand and receive payment of the fair value of their stock in
     certain mergers. However, appraisal rights are not available to holders of
     shares:

     (1)   listed on a national securities exchange;

     (2)   designated as a national market system security on an interdealer
        quotation system operated by the National Association of Securities
        Dealers, Inc.; or

     (3)   held of record by more than 2,000 stockholders;

     unless holders of stock are required to accept in the merger anything other
     than any one of the following or a combination thereof:

     (A)  shares of stock or depositary receipts of the surviving corporation in
        the merger;

     (B)  shares of stock or depositary receipts of another corporation that, at
        the effective date of the merger, will be either:

                                      VII-7
<PAGE>   190

        (a)   listed on a national securities exchange;

        (b)   designated as a national market system security on an interdealer
             quotation system operated by the National Association of Securities
             Dealers, Inc.; or

        (c)   held of record by more than 2,000 holders; or

     (C)  cash in lieu of fractional shares of the stock or depositary receipts
        received.

     In addition, appraisal rights are not available to the holders of shares of
     the surviving corporation in the merger, if the merger does not require the
     approval of the stockholders of that corporation.

(ii)  LASMO Shareholders

     Under English law, shareholders do not generally have appraisal rights, as
     the concept is understood under Delaware law, and LASMO's articles of
     association do not contain any appraisal rights.

     Certain limited rights exist where an offeror who, pursuant to a takeover
     offer for a company, has acquired or contracted to acquire not less than 90
     per cent. in value of the shares to which the offer relates, seeks to
     acquire outstanding minority shareholdings pursuant to the compulsory
     acquisition provisions under the Companies Act.

     Similarly, under a scheme of reconstruction under Section 110 of the UK
     Insolvency Act 1986, a shareholder can require the liquidator to abstain
     from carrying the resolution into effect, or to purchase his/her interest
     at a price agreed or determined by arbitration.

     Additionally, any shareholder who complains that the affairs of the company
     are being conducted, or that the directors' powers are being exercised, in
     a manner unfairly prejudicial to him/her or some part of the shareholders
     (including himself/herself), or in disregard of his/her proper interests as
     a shareholder, may apply to the High Court in England for relief. If the
     High Court finds the complaint to be justified, it may exercise its
     discretion and order the purchase of the shares on such terms, including as
     to price, as the High Court may determine.

PREEMPTIVE RIGHTS

(i)  Amerada Hess Stockholders

     Under Delaware law, a stockholder is not entitled to preemptive rights to
     subscribe for additional issues of stock or any security convertible into
     stock unless they are specifically granted in the certificate of
     incorporation. Such rights are not provided in the Amerada Hess certificate
     of incorporation.

(ii)  LASMO Shareholders

     Under English law, the issue for cash of:

     (1)   equity securities, being those which, with respect to dividends or
        capital, carry a right to participate beyond a specified amount; or

     (2)   rights to subscribe for, or convert, into equity securities;

     must be offered first to the existing equity shareholders in proportion to
     the respective nominal value of their holdings, unless a special resolution
     to the contrary has been passed by shareholders in a general meeting, or
     the articles of association provide otherwise.

     It is customary for many English companies listed on the London Stock
     Exchange to pass a resolution on an annual basis to authorise the board of
     directors to disapply pre-emption rights in respect of a specified amount
     of share capital, generally five per cent. of issued share capital, without
     pre-emption rights.

AMENDMENT OF GOVERNING INSTRUMENTS

(i)  Amerada Hess Stockholders

     Under Delaware law, unless the certificate of incorporation requires a
     greater vote, an amendment to the certificate of incorporation requires:

     (1)    the recommendation of the board of directors;

                                      VII-8
<PAGE>   191

     (2)   the affirmative vote of a majority of the outstanding stock entitled
        to vote thereon; and

     (3)   the affirmative vote of a majority of the outstanding stock of each
        class entitled to vote thereon as a class.

     The certificate of incorporation of Amerada Hess provides that Amerada Hess
     reserves the right to amend, alter, change or repeal any provision
     contained in the certificate of incorporation, in the manner prescribed by
     statute except that Article Fifth (relating to classification of directors,
     removal of directors, shareholder action and certain related matters)
     thereof may only be amended by the affirmative vote of holders of 80 per
     cent. of the outstanding voting power of all the then outstanding shares of
     capital stock entitled to vote and Article Ninth (relating to certain
     business combinations) may be amended by the affirmative vote of holders of
     two-thirds of the outstanding shares of capital stock entitled to vote. All
     rights conferred upon stockholders in the certificate of incorporation are
     granted subject to this reservation.

     Under Delaware law, stockholders have the power to adopt, amend or repeal
     by-laws unless the certificate of incorporation gives those powers to the
     directors of the corporation.

     The by-laws of Amerada Hess provide that any provision of the by-laws may
     be altered or repealed at any regular or special meeting of the
     stockholders or the board of directors if notice of the proposed alteration
     or repeal is set forth in the notice of such meeting, by the affirmative
     vote of a majority of the capital stock entitled to vote, except that
     certain provisions may be altered and repealed only by the affirmative vote
     of 80 per cent. of the holders of capital stock entitled to vote.

(ii)  LASMO Shareholders

     Under English law, shareholders have the power to amend:

     (1)   the objects, or purpose, clause in a company's memorandum of
        association; and

     (2)   any provisions of the company's articles of association;

     by special resolution, subject to, in the case of amendments to the objects
     clause of the memorandum of association, the right of dissenting
     shareholders to apply to the courts to cancel the amendments within 21 days
     of the passing of the resolution.

     Under English law, the board of directors is not authorised to change the
     memorandum or articles of association.

     Amendments affecting the rights of the holders of any class of shares may,
     depending on the rights attached to the class and the nature of the
     amendments, also require approval by extraordinary resolution of the
     classes affected in separate class meetings.

     LASMO's articles of association provide for the variation of class rights
     if sanctioned in writing either by holders of not less than 75 per cent. in
     nominal value of the issued shares in the class, or an extraordinary
     resolution of the class affected in a separate class meeting.

STOCK CLASS RIGHTS

(i)  Amerada Hess Stockholders

     Under Delaware law, any change to the rights of holders of the Amerada Hess
     Shares or any series of preferred stock would require an amendment to the
     Amerada Hess certificate of incorporation.

     Delaware law provides that the holders of shares of a class or series shall
     be entitled to vote as a class upon a proposed amendment if the amendment
     will:

     (1)   increase or decrease the authorised shares of the class or series;

     (2)   increase or decrease the par value of the shares of the class or
        series; or

     (3)   alter or change the powers, preferences or special rights of the
        shares of the class or series so as to affect them adversely.

     Under its certificate of incorporation Amerada Hess has the right to issue
     shares of common stock as well as shares of preferred stock.

                                      VII-9
<PAGE>   192

     The shares of authorised common stock shall be identical in all respects
     and have equal rights and privileges. Without action by the stockholders,
     such shares of common stock may be issued by Amerada Hess from time to time
     for such consideration as may be fixed by the board of directors; provided,
     however, that such consideration shall not be less than par value. Any and
     all shares so issued, the full consideration for which has been paid or
     delivered shall be deemed fully paid stock non-assessable. No holder of
     shares of common stock shall be entitled as a matter of right, preemptive
     or otherwise, to subscribe for, purchase or receive any shares of the stock
     of Amerada Hess of any class, now or hereafter authorised, or any options
     or warrants for such stock or securities convertible into or exchangeable
     for such stock, or any shares held in the treasury of Amerada Hess.

     The board of directors shall have the authority to issue the shares of the
     preferred stock from time to time on such terms and conditions as it may
     determine, and to divide the preferred plan into one or more classes or
     series and in connection with the creation of any such class or series to
     fix by the resolution or resolutions providing for the issue of shares
     thereof the designations, powers, preferences and relative participating,
     optional or other special rights of such class or series, and the
     qualifications, limitations, or restrictions thereof, to the full extent
     now or hereafter permitted by law. The number of authorised shares of
     preferred stock may be increased or decreased (but not below the number
     then outstanding) by the affirmative vote of the holders of a majority of
     the common stock, without a vote of the holders of the preferred plan,
     unless a vote of any such holders is required pursuant to the certificate
     or certificates establishing the series of preferred stock.

(ii)  LASMO Shareholders

     See "Amendment of governing instruments".

SHAREHOLDERS' VOTES ON CERTAIN TRANSACTIONS

(i)  Amerada Hess Stockholders

     Generally, under Delaware law, unless the certificate of incorporation
     provides for the vote of a larger portion of the stock, completion of a
     merger, consolidation, sale, lease or exchange of all or substantially all
     of a corporation's assets or dissolution requires:

     (1)   the approval of the board of directors; and

     (2)   approval by the vote of the holders of a majority of the outstanding
        stock or, if the certificate of incorporation provides for more or less
        than one vote per share, a majority of the votes of the outstanding
        stock of a corporation entitled to vote on the matter.

     The Amerada Hess certificate of incorporation requires the affirmative vote
     of not less than two-thirds of the capital stock having voting power to
     authorize a sale, lease or exchange of all or substantially all of the
     property and assets of Amerada Hess. Also, the certificate requires the
     affirmative vote of two-thirds of the capital stock entitled to vote (other
     than the shares held by certain defined acquiring persons) to approve
     certain business combinations with such an acquiring person.

     Under the rules of the NYSE, acquisitions involving the following require
     shareholder approval:

     (l)    the issuance of stock to a substantial securityholder, a director or
        an officer; or

     (2)   the issuance of additional shares of common stock of a listed company
        if:

        (a)   the common stock has, or will have upon issuance, voting power
             equal to or in excess of 20 per cent. of the voting power
             outstanding before the issuance of such stock; or

        (b)   the number of shares of common stock to be issued is, or will be
             upon issuance, equal to or in excess of 20 per cent. of the number
             of shares of common stock outstanding before the issuance of such
             stock.

(ii)  LASMO Shareholders

     The Companies Act provides for schemes of arrangement, which are
     arrangements or compromises between a company and any class of shareholders
     or creditors and used in certain types

                                     VII-10
<PAGE>   193

     of reconstructions, amalgamations, capital reorganisations or takeovers.
     These arrangements require the approval at a special meeting convened by
     order of the court, of:

     (1)   a majority in number of shareholders or creditors representing 75 per
        cent. in value of the capital held by, or debt owed to, the class of
        shareholders or creditors, or class thereof present and voting, either
        in person or by proxy; and

     (2)   the court.

     Once approved and sanctioned, all shareholders and creditors of the
     relevant class are bound by the terms of the scheme. A scheme of
     reconstruction under Section 110 of the UK Insolvency Act 1986 may be made
     when a company is being wound-up voluntarily. Under the terms of such a
     scheme and with the sanction of a special resolution of the shareholders,
     the whole or part of the company's business or property is transferred to a
     second company. Any dissenting shareholder can require the liquidator to
     abstain from carrying the resolution into effect or to purchase his/her
     interest at a price agreed or determined by arbitration.

     The Companies Act also provides:

     (1)   that where a takeover offer is made for the shares of an English
        company; and

     (2)   within four months of the date of the offer, the offeror has acquired
        or contracted to acquire at least nine-tenths in value of the shares of
        any class to which the offer relates;

     the offeror may, within two months of reaching the nine-tenths level,
     require shareholders who do not accept the offer to transfer their shares
     on the terms of the offer. A dissenting shareholder may object to the
     transfer or its proposed terms by applying to the court within six weeks of
     the date on which notice of the transfer was given. In the absence of fraud
     or oppression, the court is unlikely to order that the acquisition not take
     effect, but it may specify terms of the transfer that it finds appropriate.
     A minority shareholder is also entitled in these circumstances, in the
     alternative, to require the offeror to acquire his/her shares on the terms
     of the offer.

     Under the Listing Rules, shareholder approval:

     (1)   is required for an acquisition or disposal by a listed company if,
        generally, the size of the company or business to be acquired or
        disposed of represents 25 per cent. or more of the size of the listed
        company; and

     (2)   may also be required for an acquisition or disposal of assets between
        a listed company and related parties, including:

        (a)   directors of the company or its subsidiaries;

        (b)   holders of ten per cent. of the nominal value of any class of the
             company's, or any holding company's, or its subsidiary's shares
             having the right to vote; or

        (c)   any of their affiliates.

RIGHTS OF INSPECTION

(i)  Amerada Hess Stockholders

     Delaware law allows any stockholder:

     (1)   to inspect:

        (a)   the corporation's stock ledger;

        (b)   a list of its stockholders; and

        (c)   its other books and records; and

     (2)   to make copies or extracts of those materials during normal business
        hours; provided, however, that:

        (a)   the stockholder makes a written request under oath stating the
             purpose of his/her inspection; and

        (b)   the inspection is for a purpose reasonably related to the person's
             interest as a stockholder.
                                     VII-11
<PAGE>   194

     The by-laws of Amerada Hess provide that the board of directors shall
     determine from time to time whether, when and under what conditions and
     regulations the accounts and books of Amerada Hess (except such as may by
     statute be specifically open to inspection) or any of them shall be open to
     the inspection of the stockholders and the stockholders' rights in this
     respect are and shall be restricted and limited accordingly.

(ii)  LASMO Shareholders

     Except when closed under the provisions of the Companies Act, the register
     and index of names of shareholders of an English company may be inspected
     during business hours:

     (1)   without payment, by its shareholders; or

     (2)   for a fee by any other person.

     In both cases, the documents may be copied for a fee.

     The shareholders of an English public company may also inspect, without
     charge, during business hours:

     (1)   minutes of meetings of the shareholders and obtain copies of the
        minutes for a fee; and

     (2)   service contracts of the company's directors, if the contracts have
        more than 12 months to run or require more than 12 months' notice to
        terminate.

     In addition, the published annual accounts of a public company are required
     to be available for shareholders at a general meeting and a shareholder is
     entitled to a copy of these accounts.

STANDARD OF CONDUCT FOR DIRECTORS

(i)  Amerada Hess Stockholders

     The DGCL does not contain specific provisions setting forth the standard of
     conduct of a director. The scope of the fiduciary duties of directors is
     generally determined by the courts of the State of Delaware. In general,
     directors have a duty to act without self-interest, on a well-informed
     basis and in a manner they reasonably believe to be in the best interest of
     the shareholders.

(ii)  LASMO Shareholders

     Under English law, a director has a fiduciary duty to act in a company's
     best interest. This duty includes obligations:

     (1)   not to create an actual or potential conflict between his/her duty to
        the company and duties to any other person or his/her personal
        interests; and

     (2)   to exercise his/her powers only in accordance with the memorandum and
        articles of association of the company.

     In addition, a director must exercise reasonable care and skill. The
     precise scope of this duty is unclear, but the test appears to be both
     subjective (i.e., was the director's conduct that of a reasonably diligent
     person who has the knowledge and experience of the director) and objective
     (i.e., was the director's conduct that of a reasonably diligent person
     having the knowledge and experience that a director should have).

     The Companies Act contains restrictions on a company's power to make loans
     and confer other benefits to directors and persons connected with them.

CLASSIFICATION OF THE BOARD OF DIRECTORS

(i)  Amerada Hess Stockholders

     Delaware law permits the certificate of incorporation or a
     stockholder-adopted by-law to provide that directors be divided into one,
     two or three classes, with the term of office of one class of directors to
     expire each year.

     The Amerada Hess certificate of incorporation provides for classification
     of its board of directors into three classes, as nearly equal in number as
     possible. Each class is elected to a term expiring at the annual meeting of
     stockholders held in the third year following the year of such election.
                                     VII-12
<PAGE>   195

(ii)  LASMO Shareholders

     There are no provisions under English law which govern the term of office
     of directors, although shareholder approval is required if a director's
     contract of employment is for a period of more than five years.

     The Combined Code, which contains principles of good governance and a code
     of best practice and is appended to the Listing Rules, recommends that the
     notice period under directors' service contracts should ideally be set at
     one year or less.

     LASMO articles of association provide that at every general meeting one
     third of the directors must retire. These retiring directors may be
     re-appointed by the meeting.

REMOVAL OF DIRECTORS

(i)  Amerada Hess Stockholders

     Delaware law provides that a director may be removed with or without cause
     by the holders of a majority in voting power of the shares entitled to vote
     at an election of directors, except that:

     (1)   members of a classified board of directors may be removed only for
        cause, unless the certificate of incorporation provides otherwise; and

     (2)   directors may not be removed in certain situations in the case of a
        corporation having cumulative voting.

     Even though Amerada Hess has a classified board of directors, the by-laws
     of Amerada Hess provide that any director may be removed at any time,
     either for or without cause, but only by the affirmative vote of holders of
     at least 80 per cent. of the voting power of the shares of capital stock
     then entitled to vote.

     Amerada Hess does not have cumulative voting.

(ii)  LASMO Shareholders

     Under the Companies Act, shareholders may remove a director without cause
     by ordinary resolution, irrespective of any provisions of the company's
     articles of association or service contract the director has with the
     company, provided, however, that 28 clear days' notice of the resolution is
     given to the company.

VACANCIES ON THE BOARD OF DIRECTORS

(i)  Amerada Hess Stockholders

     Under Delaware law, unless otherwise provided in the certificate of
     incorporation or the by-laws the following vacancies may be filled by a
     vote of a majority of the directors then in office:

     1.    vacancies on a board of directors; and

     2.    newly created directorships resulting from an increase in the
        authorized number of directors.

     However, if the holders of any specific class of stock are entitled to
     elect directors, vacancies and newly created directorships of the class may
     only be filled by a majority of the directors elected by the class. In the
     case of a classified board, directors elected to fill vacancies or newly
     created directorships will hold office until the next election of the class
     for which the directors have been chosen.

     (Except as otherwise provided in the rights of a class or series of
     preferred stock having preference over common stock under specified
     circumstances, the by-laws of Amerada Hess provide that vacancies created
     by death, resignation, removal or disqualification and newly created
     directorships resulting from any increase in the authorised number of
     directors may be filled by the affirmative vote of a majority of the
     directors remaining in office, although less than a quorum. Each director
     so chosen shall hold office for the remainder of the full term of the class
     of directors in which the new directorship was created or the vacancy
     occurred and until such director's successor shall have been elected and
     qualified).

                                     VII-13
<PAGE>   196

(ii)  LASMO Shareholders

     Under English law, shareholders may by ordinary resolution, at a meeting at
     which any director retires, appoint a person to be a director:

     1.    to fill a vacancy; or

     2.    to become an additional director, subject to any maximum provided in
        the company's articles of association.

     The board of directors has the power to appoint a director to serve until
     the next general meeting of the company, whereupon the director concerned
     is required to retire, but will be eligible for re-election. However, the
     total number of directors shall not exceed any maximum number fixed in
     accordance with the company's articles of association.

     LASMO's articles of association provide that the minimum number of
     directors shall be two and that there shall be no maximum, unless and until
     otherwise determined by the company by ordinary resolution.

LIABILITY OF DIRECTORS AND OFFICERS

(i)  Amerada Hess Stockholders

     Delaware law permits a corporation's certificate of incorporation to
     include a provision eliminating or limiting the personal liability of a
     director to the corporation and its stockholders for damages arising from a
     breach of fiduciary duty as a director. However, no provision can limit the
     liability of a director for:

     (1)   any breach of his/her duty of loyalty to the corporation or its
        stockholders;

     (2)   acts or omissions not in good faith or that involve intentional
        misconduct or a knowing violation of law;

     (3)   intentional or negligent payment of unlawful dividends or stock
        purchases or redemptions; or

     (4)   any transaction from which he/she derives an improper personal
        benefit.

     The Amerada Hess certificate of incorporation provides that a director of
     Amerada Hess shall not be personally liable to Amerada Hess or its
     shareholders for monetary damages for breach of fiduciary duty as a
     director, except for liability which would otherwise exist under applicable
     law (i) for any breach of the director's duty of loyalty to Amerada Hess
     and its shareholders, (ii) for acts or omissions not in good faith or which
     involve intentional misconduct or a knowing violation of law, (iii) under
     Section 174 of the DGCL (unlawful payment of dividend or unlawful stock
     purchase or redemption) or (iv) for any transaction from which the director
     derived any improper personal benefit.

     If the DGCL is amended after approval by the stockholders of this provision
     in the certificate of incorporation to authorise corporate action further
     eliminating or limiting the personal liability of directors, then the
     liability of a director of the corporation shall be eliminated or limited
     to the fullest extent permitted by the DGCL, as so amended. The certificate
     of incorporation also provide that any repeal or modification of this
     provision in the certificate of incorporation shall not adversely affect
     any right or protection of a director of the corporation existing at the
     time of such repeal or modification.

(ii)  LASMO Shareholders

     English law does not permit a company to exempt any director, officer of
     the company or any person employed by the company as an auditor, from any
     liability arising from negligence, default, breach of duty or breach of
     trust against the company.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

(i)  Amerada Hess Stockholders

     Delaware law provides that a corporation may indemnify any officer or
     director who is made a party to any suit or proceeding on account of being
     a director, officer or employee of the corporation against expenses,
     including attorney's fees, judgments, fines and amounts paid in settlement
                                     VII-14
<PAGE>   197

     reasonably incurred by him/her in connection with the action, through,
     among other things, a majority vote of a quorum consisting of directors who
     were not parties to the suit or proceeding if the officer or director:

     (1)   acted in good faith and in a manner he/she reasonably believed to be
        in the best interests of the corporation; and

     (2)   in a criminal proceeding, had no reasonable cause to believe his/her
        conduct was unlawful.

     The by-laws of Amerada Hess contain specific authority for indemnification
     by the corporation of current and former directors, officers, employees or
     agents of the corporation.

     Amerada Hess maintains policies of insurance under which Amerada Hess and
     its directors and officers are insured subject to specified exclusions and
     deductibles and maximum amounts against loss arising from any claim which
     may be made against Amerada Hess or any director or officer of Amerada Hess
     by reason of any breach of duty, neglect, error, misstatement, omission or
     act done or alleged to have been done while acting in their respective
     capabilities.

(ii)  LASMO Shareholders

     English law does not permit a company to indemnify:

     (1)   a director or officer of the company; or

     (2)   any person employed by the company as an auditor;

     against any liability arising from negligence, default, breach of duty or
     breach of trust against the company, except that indemnification is allowed
     for liabilities incurred in proceedings in which:

     (1)   judgment is entered in favour of the director or officer, or the
        director or officer is acquitted; or

     (2)   the director or officer is held liable, but the court finds that
        he/she acted honestly and reasonably and that relief should be granted.

     The Companies Act enables companies to purchase and maintain insurance for
     directors, officers and auditors against liabilities arising from
     negligence, default, breach of duty or breach of trust against the company.

     LASMO's articles of association authorise the company to purchase and
     maintain such insurance for any directors, officers or auditors of the
     company.

     See also "Liability of directors and officers".

SHAREHOLDER SUITS

(i)  Amerada Hess Stockholders

     Under Delaware law, a stockholder may initiate a derivative action to
     enforce a right of a corporation if the corporation fails to enforce the
     right itself. The complaint must:

     (1)   state that the plaintiff was a stockholder at the time of the
        transaction of which the plaintiff complains or that the plaintiffs
        shares thereafter devolved on the plaintiff by operation of law; and

     (2)   (a)   allege with particularity the efforts made by the plaintiff to
             obtain the action the plaintiff desires from the directors and the
             reasons for the plaintiff's failure to obtain the action; or

        (b)   state the reasons for not making the effort.

     Additionally, the plaintiff must remain a stockholder through the duration
     of the derivative suit. The action will not be dismissed or compromised
     without the approval of the Delaware Court of Chancery.

                                     VII-15
<PAGE>   198

(ii)  LASMO Shareholders

     While English law only permits a shareholder to initiate a lawsuit on
     behalf of the company in limited circumstances, the Companies Act permits a
     shareholder whose name is on the register of shareholders of the company to
     apply for a court order:

     (1)    when the company's affairs are being or have been conducted in a
        manner unfairly prejudicial to the interests of all or some
        shareholders, including the shareholder making the claim; or

     (2)   when any act or omission of the company is or would be so
        prejudicial.

     A court has wide discretion in granting relief, and may authorize civil
     proceedings to be brought in the name of the company by a shareholder on
     terms that the court directs. Except in these limited circumstances,
     English law does not generally permit class action lawsuits by shareholders
     on behalf of the company, or on behalf of other shareholders.

CERTAIN PROVISIONS RELATING TO SHARE ACQUISITIONS

(i)  Amerada Hess Stockholders

     Section 203 of the DGCL prohibits "business combinations", including
     mergers, sales and leases of assets, issuances of securities and similar
     transactions by a corporation or a subsidiary with an "interested
     stockholder" who beneficially owns 15 per cent. or more of a corporation's
     voting stock, within three years after the person or entity becomes an
     interested stockholder, unless:

     (1)   prior to the time at which the stockholder became an interested
        stockholder, the business combination or the transaction that caused the
        person to become an interested stockholder is approved by the board of
        directors of the corporation;

     (2)   after completion of the transaction in which the person becomes an
        interested stockholder, the interested stockholder holds at least 85 per
        cent. of the voting stock of the corporation not including (i) shares
        held by officers and directors of interested stockholders and (ii)
        shares held by specified employee benefit plans; or

     (3)   after the person becomes an interested stockholder, the business
        combination is approved by the board and holders of at least two thirds
        of the outstanding voting stock, excluding shares held by the interested
        stockholder.

(ii)  LASMO Shareholders

     In the case of a company listed on the London Stock Exchange, shareholder
     approval must be obtained for certain acquisitions or disposals of assets
     involving directors, substantial shareholders or their associates. In
     addition, takeovers of public companies, whether or not listed on the
     London Stock Exchange, are regulated by the City Code, which is:

     (1)   comprised of non-statutory rules unenforceable at law; and

     (2)   administered by the Panel, a body consisting of representatives of
        City of London financial and professional institutions, which oversees
        the conduct of takeovers.

     The City Code provides that when:

     (1)   any person acquires, whether by a series of transactions over a
        period of time or not, shares which, together with shares held or
        acquired by persons acting in concert with him/her, represent 30 per
        cent or more of the voting rights of a public company; or

     (2)   any person, together with persons acting in concert with him/her,
        holds at least 30 per cent. but not more than 50 per cent. of the voting
        rights and that person, or any person acting in concert with him/her,
        acquires any additional shares;

     the person must generally make an offer for all of the equity shares of the
     company, whether voting or nonvoting, and any class of voting non-equity
     shares of the company held by that person or any person acting in concert
     with him/her, for cash, or accompanied by a cash alternative, at not less
     than the highest price paid by the person or these persons for the relevant
     shares during the 12 months preceding the date of the offer.

                                     VII-16
<PAGE>   199

ANTI-TAKEOVER MEASURES

(i)  Amerada Hess Stockholders

     Under Delaware law, directors generally have a duty to act without
     self-interest, on a well-informed basis and in a manner they reasonably
     believe to be in the best interests of the stockholders.

     Nevertheless, a Delaware court will generally apply a policy of judicial
     deference to board of directors decisions to adopt anti-takeover measures
     in the face of a potential takeover where the directors are able to show
     that:

     (1)   they had reasonable grounds for believing that there was a danger to
        corporate policy and effectiveness from an acquisition proposal; and

     (2)   the board action taken was reasonable in relation to the threat
        posed.

(ii)  LASMO Shareholders

     Under English law, directors of a company have a fiduciary duty to take
     only those actions which are in the interests of the company. Generally,
     anti-takeover measures are not actions which fall within this category.

     Under the City Code, a company is prohibited from taking any action without
     the approval of its shareholders at a general meeting after:

     (1)   a bona fide offer has been communicated to its board of directors; or

     (2)   its board of directors has reason to believe that a bona fide offer
        might be imminent;

     if that action could effectively result in the offer being frustrated or in
     the shareholders being denied an opportunity to decide on its merits.

DISCLOSURE OF INTERESTS

(i)  Amerada Hess Stockholders

     Acquirers of common stock are subject to disclosure requirements under
     Section 13(d)(1) of the Exchange Act and Rule 13d-1 thereunder, which
     provide that any person who becomes the beneficial owner of more than five
     per cent of the outstanding common stock of Amerada Hess must, within ten
     days after such acquisition:

     (1)   file a Schedule 13D with the SEC disclosing specified information:
        and

     (2)   send a copy of the Schedule 13D to Amerada Hess and to each
        securities exchange on which the security is traded.

(ii)  LASMO Shareholders

     The Companies Act provides that anyone who acquires a material interest or
     becomes aware that he/she has acquired a material interest in three per
     cent. or more of any class of shares of a public company's issued share
     capital carrying rights to vote at general shareholder meetings must notify
     that company in writing of his/ her interest within two days. Thereafter,
     any increase or decrease of a whole percentage or decrease which reduces
     the interest to below three per cent. must be notified in writing to the
     company.

     In addition, the Companies Act provides that a public company may, by
     notice in writing, require a person whom the company knows or reasonably
     believes to be or to have been within the three preceding years, interested
     in the company's issued voting share capital, to:

     (1)   confirm whether this is or is not the case; and

     (2)   if this is the case, to give further information that the company
        requires relating to his/her interest and any other interest in the
        company's shares of which he/she is aware.

     The disclosure must be made within a reasonable period as specified in the
     relevant notice, which may be as short as one or two days.

     When the notice is served by a company on a person who is, or was,
     interested in shares of the company and that person fails to give the
     company any information required by the notice within the
                                     VII-17
<PAGE>   200

     time specified in the notice, the company may apply to the court for an
     order directing that the shares in question be subject to restrictions
     prohibiting, among other things:

     (1)   any transfer of the shares;

     (2)   the exercise of voting rights;

     (3)   the issue of further shares; and

     (4)   other than a liquidation, dividends and other payments.

     These restrictions may also void any agreement to transfer the shares.

LIMITATIONS ON ENFORCEABILITY OF CIVIL LIABILITIES UNDER US FEDERAL SECURITIES
LAWS

Ability to bring suits, enforce judgments and enforce US law

(i)  Amerada Hess Stockholders

     Amerada Hess is a US company incorporated under the laws of Delaware. All
     but one of its directors and officers are residents of the United States,
     and Amerada Hess has substantial assets located in the United States. As a
     result, US investors generally can initiate lawsuits in the United States
     against Amerada Hess and its directors and officers and can enforce
     lawsuits based on US federal securities laws in US courts.

(ii)  LASMO Shareholders

     LASMO is an English company located in the United Kingdom. Many of the
     directors and officers of LASMO are residents of the United Kingdom and not
     the United States. A large portion of the assets of LASMO and its directors
     and officers are located outside of the United States. As a result, US
     investors may find it difficult, in a lawsuit based on the civil liability
     provisions of the US federal securities laws, to:

     (1)   effect service within the United States upon LASMO and the directors
        and officers of LASMO located outside the United States;

     (2)   enforce in US courts or outside the United States judgments obtained
        against those persons in US courts;

     (3)   enforce in US courts judgments obtained against those persons in
        courts in jurisdictions outside the United States; and

     (4)   enforce against those persons in the United Kingdom, whether in
        original actions or in actions for the enforcement of judgments of US
        courts, civil liabilities based solely upon the US federal securities
        laws.

"Short swing" profits

(i)  Amerada Hess Stockholders

     Directors and officers of Amerada Hess are governed by rules under the
     Exchange Act that may require directors and officers to forfeit to Amerada
     Hess any "short swing" profits realized from purchases and sales, as
     determined under the Exchange Act and the rules thereunder, of Amerada Hess
     equity securities.

(ii)  LASMO Shareholders

     Directors and officers of LASMO are not subject to the Exchange Act's
     "short swing" profit rules because LASMO is currently a foreign private
     issuer under the Exchange Act, which is not subject to these rules.

     However, directors of LASMO are currently subject to applicable UK
     legislation prohibiting insider dealing. In addition, the directors have to
     comply with the Model Code of the London Stock Exchange, which provides
     that the considerations taken into account by directors when deciding
     whether or not to deal in shares of the company of which they are a
     director, must not be of a short-term nature. The Model Code also places
     additional restrictions on trading during periods prior to announcement of
     a company's results.

                                     VII-18
<PAGE>   201

PROXY STATEMENTS AND REPORTS

(i)  Amerada Hess Stockholders

     Under the Exchange Act proxy rules, Amerada Hess must comply with notice
     and disclosure requirements relating to the solicitation of proxies for
     stockholder meetings.

(ii)  LASMO Shareholders

     As a foreign private issuer, LASMO is not subject to the Exchange Act proxy
     rules. However, LASMO is governed by the Companies Act and the Listing
     Rules regulating notices of shareholder meetings, which provide that notice
     of a shareholder meeting must be accompanied by:

     (1)   a shareholder circular containing an explanation of the purpose of
        the meeting; and

     (2)   the recommendations of the board with respect to actions to be taken.

     In addition, LASMO sends LASMO ordinary shareholders a copy of its annual
     report and accounts, or a summary thereof.

     In addition, under the London Stock Exchange listing rules, LASMO is
     required to send to shareholders details relating to certain acquisitions,
     dispositions, takeovers, mergers and offers, either made by, or to respect
     of, the company, depending on their size and importance.

REPORTING REQUIREMENTS

(i)  Amerada Hess Stockholders

     As a US public company, Amerada Hess must file with the SEC, among other
     reports and notices:

     (1)   an annual report on Form 10-K within 90 days after the end of each
        fiscal year;

     (2)   quarterly reports on Form 10-Q within 45 days after the end of each
        of the first three fiscal quarters of each year; and

     (3)   current reports on Form 8-K upon the occurrence of important
        corporate events.

(ii)  LASMO Shareholders

     Under English law, LASMO must file the following documents, inter alia,
     with Companies House:

     (1)   annual accounts and report, seven months after the end of the

                                 APPENDIX VIII

                    CERTAIN PROVISIONS OF THE COMPANIES ACT

Set out below is an extract from the Companies Act:

                                    PART IXA

                                TAKEOVER OFFERS

428.  TAKEOVER OFFERS

(1)    In this Part of this Act "takeover offer" means an offer to acquire all
      the shares, or all the shares of any class or classes, in a company (other
      than shares which at the date of the offer are already held by the
      offeror), being an offer on terms which are the same in relation to all
      the shares to which the offer relates or, where those shares include
      shares of difference classes, in relation to all the shares of each class.

(2)    In subsection (1) "shares" means shares which have been allotted on the
      date of the offer but a takeover offer may include among the shares to
      which it relates all or any shares that are subsequently allotted before a
      date specified in or determined in accordance with the terms of the offer.

(3)    The terms offered in relation to any shares shall for the purpose of this
      section be treated as being the same in relation to all the shares or, as
      the case may be, all the shares of a class to which the offer relates
      notwithstanding any variation permitted by subsection (4).

(4)    A variation is permitted by this subsection where -

      (a)   the law of a country or territory outside the United Kingdom
          precludes an offer of consideration in the form or any of the forms
          specified in the terms in question or precludes it except after
          compliance by the offeror with conditions with which he is unable to
          comply or which he regards as unduly onerous; and

      (b)   the variation is such that the persons to whom an offer of
          consideration in that form is precluded are able to receive
          consideration otherwise than in that form but of substantially
          equivalent value.

(5)    The reference in subsection (1) to shares already held by the offeror
      includes a reference to shares which he has contracted to acquire but that
      shall not be construed as including shares which are the subject of a
      contract binding the holder to accept the offer when it is made, being a
      contract entered into by the holder either for no consideration and under
      seal or for no consideration other than a promise by the offeror to make
      the offer.

(6)    In the application of subsection (5) to Scotland the words "and under
      seal" shall be omitted.

(7)    Where the terms of an offer make provision for their revision and for
      acceptances on the previous terms to be treated as acceptances on the
      revised terms, the revision shall not be regarded for the purposes of this
      Part of this Act as the making of a fresh offer and references in this
      Part of this Act to the date of the offer shall accordingly be construed
      as references to the date on which the original offer was made.

(8)    In this Part of this Act the "offeror" means, subject to section 430D,
      the person making a takeover offer and the "company" means the company
      whose shares are the subject of the offer.

429.  RIGHT OF OFFEROR TO BUY OUT MINORITY SHAREHOLDERS

(1)    If, in a case in which a takeover offer does not relate to shares of
      different classes, the offeror has by virtue of acceptance of the offer
      acquired or contracted to acquire not less than nine-tenths in value of
      the shares to which the offer relates he may give notice to the holder of
      any shares to which the offer relates which the offeror has not acquired
      or contracted to acquire that he desires to acquire those shares.

(2)    If, in a case in which a takeover offer relates to shares of different
      classes, the offeror has by virtue of acceptances of the offer acquired or
      contracted to acquire not less than nine-tenths in

                                     VIII-1
<PAGE>   203

      value of the shares of any class to which the offer relates, he may give
      notice to the holder of any shares of that class which the offeror has not
      acquired or contracted to acquire that he desires to acquire those shares.

(3)    No notice shall be given under subsection (1) or (2) unless the offeror
      has acquired or contracted to acquire the shares necessary to satisfy the
      minimum specified in that subsection before the end of the period of four
      months beginning with the date of the offer and no such notice shall be
      given after the end of the period of two months beginning with the date on
      which he has acquired or contracted to acquire shares which satisfy that
      minimum.

(4)    Any notice under this section shall be given in the prescribed manner;
      and when the offeror gives the first notice in relation to an offer he
      shall send a copy of it to the company together with a statutory
      declaration by him in the prescribed form stating that the conditions for
      the giving of the notice are satisfied.

(5)    Where the offeror is a company (whether or not a company within the
      meaning of this Act) the statutory declaration shall be signed by a
      director.

(6)    Any person who fails to send a copy of a notice or statutory declaration
      as required by subsection (4) or makes such a declaration for the purposes
      of that subsection knowing it to be false or without having reasonable
      grounds for believing it to be true shall be liable to imprisonment or a
      fine, or both, and for continued failure to send the copy or declaration,
      to a daily default fine.

(7)    If any person is charged with an offence for failing to send a copy of a
      notice as required by subsection (4) it is a defence for him to prove that
      he took reasonable steps for securing compliance with that subsection.

(8)    Where during the period within which a takeover offer can be accepted the
      offeror acquires or contracts to acquire any of the shares to which the
      offer relates but otherwise than by virtue of acceptances of the offer,
      then, if -

      (a)   the value of the consideration for which they are acquired or
          contracted to be acquired ("the acquisition consideration") does not
          at that time exceed the value of the consideration specified in the
          terms of the offer; or

      (b)   those terms are subsequently revised so that when the revision is
          announced the value of the acquisition consideration, at the time
          mentioned in paragraph (a) above, no longer exceeds the value of the
          consideration specified in those terms,

      the offeror shall be treated for the purposes of this section as having
      acquired or contracted to acquire those shares by virtue of acceptances of
      the offer; but in any other case those shares shall be treated as excluded
      from those to which the offer relates.

430.  EFFECT OF NOTICE UNDER SECTION 429

(1)    The following provisions shall, subject to section 430C, have effect
      where a notice is given in respect of any shares under section 429.

(2)    The offeror shall be entitled and bound to acquire those shares on the
      terms of the offer.

(3)    Where the terms of an offer are such as to give the holder of any shares
      a choice of consideration the notice shall give particulars of the choice
      and state:

      (a)   that the holder of the shares may within six weeks from the date of
          the notice indicate his choice by a written communication sent to the
          offeror at an address specified in the notice; and

      (b)   which consideration specified in the offer is to be taken as
          applying in default of his indicating a choice as aforesaid;

      and the terms of the offer mentioned in subsection (2) shall be determined
      accordingly.

(4)    Subsection (3) applies whether or not any time-limit or the other
      conditions applicable to the choice under the terms of the offer can still
      be complied with; and if the consideration chosen by the holders of the
      shares:

      (a)   is not cash and the offeror is no longer able to provide it; or

                                     VIII-2
<PAGE>   204

      (b)   was to have been provided by a third party who is no longer bound or
          able to provide it,

      the consideration shall be taken to consist of an amount of cash payable
      by the offeror which at the date of the notice is equivalent to the chosen
      consideration.

(5)    At the end of six weeks from the date of the notice the offeror shall
      forthwith:

      (a)   send a copy of the notice to the company; and

      (b)   pay or transfer to the company the consideration for the shares to
          which the notice relates.

(6)    If the shares to which the notice relates are registered the copy of the
      notice sent to the company under subsection (5)(a) shall be accompanied by
      an instrument of transfer executed on behalf of the shareholder by a
      person appointed by the offeror; and on receipt of that instrument the
      company shall register the offeror as the holder of those shares.

(7)    If the shares to which the notice relates are transferable by the
      delivery of warrants or other instruments the copy of the notice sent to
      the company under subsection (5)(a) shall be accompanied by a statement to
      that effect, and the company shall on receipt of the statement issue the
      offeror with warrants or other instruments in respect of the shares and
      those already in issue in respect of the shares shall become void.

(8)    Where the consideration referred to in paragraph (b) of subsection (5)
      consists of shares or securities to be allotted by the offeror the
      reference in that paragraph to the transfer of the consideration shall be
      construed as a reference to the allotment of the shares or securities to
      the company.

(9)    Any sum received by a company under paragraph (b) of subsection (5) and
      any other consideration received under that paragraph shall be held by the
      company on trust for the person entitled to the shares in respect of which
      the sum or other consideration was received.

(10)   Any sum received by a company under paragraph (b) of subsection (5), and
      any dividend or other sum accruing from any other consideration received
      by a company under that paragraph, shall be paid into a separate bank
      account, being an account the balance on which bears interest at an
      appropriate rate and can be withdrawn by such notice (if any) as is
      appropriate.

(11)   Where after reasonable enquiry made at such intervals as are reasonable
      the person entitled to any consideration held on trust by virtue of
      subsection (9) cannot be found and twelve years have elapsed since the
      consideration was received or the company is wound up the consideration
      (together with any interest, dividend or other benefit that has accrued
      from it) shall be paid into court.

(12)   In relation to a company registered in Scotland, subsections (13) and
      (14) shall apply in place of subsection (11).

(13)   Where after reasonable enquiry made at such intervals as are reasonable
      the person entitled to any consideration held on trust by virtue of
      subsection (9) cannot be found and twelve years have elapsed since the
      consideration was received or the company is wound up:

      (a)   the trust shall terminate;

      (b)   the company or, as the case may be, the liquidator shall sell any
          consideration other than cash and any benefit other than cash that has
          accrued from the consideration; and

      (c)   a sum representing -

          (i)    the consideration so far as it is cash;

          (ii)   the proceeds of any sale under paragraph (b) above; and

          (iii)  any interest, dividend or other benefit that has accrued from
               the consideration,

      shall be deposited in the name of the Accountant of Court in a bank
      account such as is referred to in subsection (10) and the receipt for the
      deposit shall be transmitted to the Account of Court.

(14)   Section 58 of the Bankruptcy (Scotland) Act 1985 (so far as consistent
      with this Act) shall apply with any necessary modifications to sums
      deposited under subsection (13) as that section applies to sums deposited
      under section 57(1)(a) of that Act.

                                     VIII-3
<PAGE>   205

(15)   The expenses of any such enquiry as is mentioned in subsection (11) or
      (13) may be defrayed out of the money or other property held on trust for
      the person or persons to whom the enquiry relates.

430A. RIGHT OF MINORITY SHAREHOLDER TO BE BOUGHT OUT BY OFFEROR

(1)    If a takeover offer relates to all the shares in a company and at any
      time before the end of the period within which the offer can be accepted:

      (a)   the offeror has by virtue of acceptances of the offer acquired or
          contracted to acquire some (but not all) of the shares to which the
          offer relates; and

      (b)   those shares, with or without any other shares in the company which
          he has acquired or contracted to acquire, amount to not less than
          nine-tenths in value of all the shares in the company, the holder of
          any shares to which the offer relates who has not accepted the offer
          may by a written communication addressed to the offeror require him to
          acquire those shares.

(2)    If a takeover offer relates to shares of any class or classes and at any
      time before the end of the period within which the offer can be accepted:

      (a)   the offeror has by virtue of acceptances of the offer acquired or
          contracted to acquire some (but not all) of the shares of any class to
          which the offer relates; and

      (b)   those shares, with or without any other shares of that class which
          he has acquired or contracted to acquire, amount to not less than
          nine-tenths in value of all the shares of that class,

      the holder of any shares of that class who has not accepted the offer may
      by a written communication addressed to the offeror require him to acquire
      those shares.

(3)    Within one month of the time specified in subsection (1) or, as the case
      may be, subsection (2) the offeror shall give any shareholder who has not
      accepted the offer notice in the prescribed manner of the rights that are
      exercisable by him under that subsection; and if the notice is given
      before the end of the period mentioned in that subsection it shall state
      that the offer is still open for acceptance.

(4)    A notice under subsection (3) may specify a period for the exercise of
      the rights conferred by this section and in that event the rights shall
      not be exercisable after the end of that period; but no such period shall
      end less than three months after the end of the period within which the
      offer can be accepted.

(5)    Subsection (3) does not apply if the offeror has given the shareholder a
      notice in respect of the shares in question under section 429.

(6)    If the offeror fails to comply with subsection (3) he and, if the offeror
      is a company, every officer of the company who is in default or to whose
      neglect the failure is attributable, shall be liable to a fine and for
      continued contravention, to a daily default fine.

(7)    If an offeror other than a company is charged with an offence for failing
      to comply with subsection (3) it is a defence for him to prove that he
      took all reasonable steps for securing compliance with that subsection.

430B. EFFECT OF REQUIREMENT UNDER SECTION 430A

(1)    The following provisions shall, subject to section 430C, have effect
      where a shareholder exercises his rights in respect of any shares under
      section 430A.

(2)    The offeror shall be entitled and bound to acquire those shares on the
      terms of the offer or on such other terms as may be agreed.

(3)    Where the terms of an offer are such as to give the holder of shares a
      choice of consideration the holder of the shares may indicate his choice
      when requiring the offeror to acquire them and the notice given to the
      holder under section 430A(3) -

      (a)   shall give particulars of the choice and of the rights conferred by
          this subsection; and

                                     VIII-4
<PAGE>   206

      (b)   may state which consideration specified in the offer is to be taken
          as applying in default of his indicating a choice;

      and the terms of the offer mentioned in subsection (2) shall be determined
      accordingly.

(4)    Subsection (3) applies whether or not any time-limit or other conditions
      applicable to the choice under the terms of the offer can still be
      complied with; and if the consideration chosen by the holder of the shares
      -

      (a)   is not cash and the offeror is no longer able to provide it; or

      (b)   was to have been provided by a third party who is no longer bound or
          able to provide it,

      the consideration shall be taken to consist of an amount of cash payable
      by the offeror which at the date where the holder of the shares requires
      the offeror to acquire them is equivalent to the chosen consideration.

430C. APPLICATIONS TO THE COURT

(1)    Where a notice is given under section 429 to the holder of any shares the
      court may, on an application made by him within six weeks from the date on
      which the notice was given -

      (a)   order that the offeror shall not be entitled and bound to acquire
          the shares; or

      (b)   specify terms of acquisition different from those of the offer.

(2)    If an application to the court under subsection (1) is pending at the end
      of the period mentioned in subsection (5) of section 430 that subsection
      shall not have effect until the application has been disposed of.

(3)    Where the holder of any shares exercises his rights under section 430A
      the court may, on an application made by him or the offeror, order that
      the terms on which the offeror is entitled and bound to acquire the shares
      shall be such as the court thinks fit.

(4)    No order for costs or expenses shall be made against a shareholder making
      an application under subsection (1) or (3) unless the court considers -

      (a)   that the application was unnecessary, improper or vexations; or

      (b)   that there has been unreasonable delay in making the application or
          unreasonable conduct on his part in conducting the proceedings on the
          application.

(5)    Where a takeover offer has not been accepted to the extent necessary for
      entitling the offeror to give notices under subsection (1) or (2) of
      section 429 the court may, on the application of the offeror, make an
      order authorising him to give notices under that subsection if satisfied -

      (a)   that the offeror has after reasonable enquiry been unable to trace
          one or more of the persons holding shares to which the offer relates;

      (b)   that the shares which the offeror has acquired or contracted to
          acquire by virtue of acceptances of the offer, together with the
          shares held by the person or persons mentioned in paragraph (a),
          amount to not less than the minimum specified in that subsection; and

      (c)   that the consideration offered is fair and reasonable;

      but the court shall not make an order under this subsection unless it
      considers that it is just and equitable to do so having regard, in
      particular, to the number of shareholders who have been traced but who
      have not accepted the offer.

430D. JOINT OFFERS

(1)    A takeover offer may be made by two or more persons jointly and in that
      event this Part of this Act has effect with the following modifications.

(2)    The conditions for the exercise of the rights conferred by sections 429
      and 430A shall be satisfied by the joint offerors acquiring or contracting
      to acquire the necessary shares jointly (as respects acquisitions by
      virtue of acceptances of the offer) and either jointly or separately (in
      other cases); and, subject to the following provisions, the rights and
      obligations of the offeror under those

                                     VIII-5
<PAGE>   207

      sections and sections 430 and 430B shall be respectively joint rights and
      joint and several obligations of the joint offerors.

(3)    It shall be a sufficient compliance with any provision of those sections
      requiring or authorising a notice or other document to be given or sent by
      or to the joint offerors that it is given or sent by or to any of them;
      but the statutory declaration required by section 429(4) shall be made by
      all of them and, in the case of a joint offeror being a company, signed by
      a director of that company.

(4)    In sections 428, 430(8) and 430E references to the offeror shall be
      construed as references to the joint offerors or any of them.

(5)    In sections 430(6) and (7) references to the offeror shall be construed
      as references to the joint offerors or such of them as they may determine.

(6)    In sections 430(4)(a) and 430B(4)(a) references to the offeror being no
      longer able to provide the relevant consideration shall be construed as
      references to none of the joint offerors being able to do so.

(7)    In section 430C references to the offeror shall be construed as
      references to the joint offerors except that any application under
      subsection (3) or (5) may be made by any of them and the reference in
      subsection (5)(a) to the offeror having been unable to trace one or more
      of the persons holding shares shall be construed as a reference to none of
      the offerors having been able to do so.

430E. ASSOCIATES

(1)    The requirement in section 428(1) that a takeover offer must extend to
      all the shares, or all the shares of any class or classes, in a company
      shall be regarded as satisfied notwithstanding that the offer does not
      extend to shares which associates of the offeror hold or have contracted
      to acquire; but, subject to subsection (2), shares which any such
      associate holds or has contracted to acquire, whether at the time when the
      offer is made or subsequently, shall be disregarded for the purposes of
      any reference in this Part of this Act to the shares to which a takeover
      offer relates.

(2)    Where during the period within which a takeover offer can be accepted any
      associate of the offeror acquires or contracts to acquire any of the
      shares to which the offer relates, then, if the condition specified in
      subsection 8(a) or (b) of section 429 is satisfied as respects those
      shares they shall be treated for the purposes of that section as shares to
      which the offer relates.

(3)    In section 430(A)(1)(b) and (2)(b) the reference to shares which the
      offeror has acquired or contracted to acquire shall include a reference to
      shares which any associate of his has acquired or contracted to acquire.

(4)    In this clause "associate", in relation to an offeror, means -

      (a)   a nominee of the offeror;

      (b)   a holding company, subsidiary or fellow subsidiary of the offeror or
          a nominee of such a holding company, subsidiary or fellow subsidiary;

      (c)   a body corporate in which the offeror is substantially interested;
          or

      (d)   any person who is, or is a nominee of, a party to an agreement with
          the offeror for the acquisition of, or of an interest in, the shares
          which are the subject of the takeover offer, being an agreement which
          includes provisions imposing obligations or restrictions such as are

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Amerada Hess Corporation is a Delaware corporation subject to the
applicable provisions of the Delaware General Corporation Law (the "DGCL")
related to the limitation of director liability, indemnification of directors
and officers and insurance against director and officer liability maintained by
a corporation on behalf of directors and officers.

     The DGCL permits a corporation's certificate of incorporation to eliminate
or limit the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
provided that the relevant provision does not eliminate or limit the liability
of a director (a) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (b) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (c) for
unlawful payment of a dividend or approval of an unlawful stock purchase or
redemption or (d) for any transaction from which the director derived an
improper personal benefit.

     The DGCL permits a corporation to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation), by
reason of the fact that such person is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such action, suit or proceeding if
such person acted in good faith and in a manner such person reasonably believed
to be in or not opposed to the best interests of the corporation, and, with
respect to any criminal action or proceeding, had no reasonable cause to believe
the relevant conduct was unlawful.

     In any threatened, pending or completed action or suit by or in the right
of a corporation, the DGCL permits a corporation to indemnify any person who was
or is a party or is threatened to be made a party to any such action or suit by
reason of the fact that such person acted in any of the capacities set forth
above against expenses (including attorneys' fees) actually and reasonably
incurred by such person in connection with the defense or settlement of such
action if such person acted in good faith and in a manner such person reasonably
believed to be in or not opposed to the best interests of the corporation,
except that no indemnification may be made in respect of any claim or issue as
to which such person shall have been adjudged liable to the corporation unless
and only to the extent that the Court of Chancery or the court in which such
action was brought determines on application that, despite the adjudication of
liability but in view of all the circumstances of the case, the person is fairly
and reasonably entitled to indemnity for such expenses as the Court of Chancery
or such other court deems proper.

     The DGCL requires a corporation to indemnify a director or officer who has
been successful on the merits or otherwise in the defense of any action, suit or
proceeding referred to in the previous two paragraphs or in defense of any
claim, issue or matter therein against expenses actually and reasonably incurred
in connection therewith. Corporations may pay expenses incurred by an officer or
director in defending any proceeding in advance of the final disposition of the
matter on receipt of an undertaking by or on behalf of such person to repay such
amount if it is ultimately determined that the person is not entitled to
indemnity. The indemnification provided for by the DGCL is not exclusive of any
other rights to which the indemnified party may be entitled under any bylaw,
agreement, vote of stockholders or disinterested directors or otherwise.

     Amerada Hess Corporation's Restated Certificate of Incorporation and
By-Laws provide for the indemnification by Amerada Hess Corporation of each
director and officer of Amerada Hess Corporation to the fullest extent permitted
by the DGCL.

ITEM 22.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement;

             (i) to include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;

             (ii) to reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20 percent change
        in the maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and

             (iii) to include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

                                      II-3
<PAGE>   219

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

          (4) If the registrant is a foreign private issuer, to file a
     post-effective amendment to the registration statement to include any
     financial statements required by Item 8.A. of Form 20-F at the start of any
     delayed offering or throughout a continuous offering. Financial statements
     and information otherwise required by Section 10(a)(3) of the Act need not
     be furnished, provided, that the registrant includes in the prospectus, by
     means of a post-effective amendment, financial statements required pursuant
     to this paragraph (a)(4) and other information necessary to ensure that all
     other information in the prospectus is at least as current as the date of
     those financial statements. Notwithstanding the foregoing, with respect to
     registration statements on Form F-3, a post-effective amendment need not be
     filed to include financial statements and information required by Section
     10(a)(3) of the Act or Rule 3-19 of this chapter if such financial
     statements and information are contained in periodic reports filed with or
     furnished to the Commission by the registrant pursuant to Section 13 or
     Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
     by reference in the Form F-3.

          (5) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934
     (and, where applicable, each filing of an employee benefit plan's annual
     report pursuant to Section 15(d) of the Securities Exchange Act of 1934)
     that is incorporated by reference in the registration statement shall be
     deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

          (6) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
     Form, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the registration statement through the date of responding
     to the request.

          (7) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the registration statement when
     it became effective.

          (8) That prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.

          (9) That every prospectus: (i) that is filed pursuant to paragraph (8)
     immediately preceding, or (ii) that purports to meet the requirements of
     Section 10(a)(3) of the Act and is used in connection with an offering of
     securities subject to Rule 415, will be filed as a part of an amendment to
     the registration statement and will not be used until such amendment is
     effective, and that, for purposes of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling
                                      II-4
<PAGE>   220

person in connection with the securities being registered, the registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

     Pursuant to the requirements of the Securities Act, the registrant has duly

undersigned, thereunto duly authorized, in the City of New York, State of New
York, on the 21st day of November, 2000.
