                               SUMMARY TERM SHEET

     Amerada Hess (Cayman) Limited is offering to purchase all of the existing
unconditionally allotted or issued and fully paid ordinary shares and any
further ordinary shares which are unconditionally allotted or issued and fully
paid before the date on which the offer (including any subsequent offering
period) expires (including the associated series A junior participating
preferred share purchase rights) of Triton Energy Limited at a price of $45.00
per ordinary share, net to the seller in cash. The following are some of the
questions you, as a shareholder of Triton, may have and answers to those
questions.

     WE URGE YOU TO READ CAREFULLY THE REMAINDER OF THIS OFFER TO PURCHASE AND
THE LETTER OF TRANSMITTAL BECAUSE THE INFORMATION IN THIS SUMMARY TERM SHEET
DOES NOT CONTAIN ALL OF THE INFORMATION YOU SHOULD CONSIDER BEFORE TENDERING
YOUR ORDINARY SHARES. ADDITIONAL IMPORTANT INFORMATION IS CONTAINED IN THE
REMAINDER OF THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL.

- - WHO IS OFFERING TO BUY MY SECURITIES?

     Our name is Amerada Hess (Cayman) Limited. We are a Cayman Islands company
formed for the purpose of making this offer. We are a wholly owned subsidiary of
Amerada Hess Corporation, a public company incorporated under the laws of
Delaware. See the "Introduction" to this Offer to Purchase. We are making the
offer pursuant to an acquisition agreement dated as of July 9, 2001 among us,
Amerada Hess and Triton.

- - HAVE TRITON'S PRINCIPAL SHAREHOLDERS AGREED TO SELL THEIR SHARES?

     HM4 Triton, L.P., an affiliate of Hicks, Muse, Tate & Furst Incorporated,
and certain other shareholders of Triton have agreed to sell to us, and we have
agreed to purchase from them, all of their ordinary shares and 8% convertible
preference shares, representing approximately 37.7% of the outstanding ordinary
shares assuming the conversion of such preference shares (34.2% on a fully
diluted basis). When we acquire the ordinary shares and preference shares owned
by the shareholders who are party to the principal shareholders agreement, it
will not be possible under Cayman Islands law for another person to purchase
Triton's entire share capital without our agreement. See Section 11 -- "Purpose
of the Offer; Plans for the Company; Certain Agreements" in this Offer to
Purchase.

- - WHAT ARE THE CLASSES AND AMOUNTS OF SECURITIES SOUGHT IN THE OFFER?

     We are seeking to purchase all of the existing unconditionally allotted or
issued and fully paid ordinary shares and any further ordinary shares which are
unconditionally allotted or issued and fully paid before the date on which the
offer expires (including the associated series A junior participating preferred
share purchase rights) of Triton. We are not making an offer for preference
shares or options to purchase ordinary shares (although procedures will be
established to permit the conditional tender of ordinary shares for which
options can be exercised or into which preference shares may be converted). See
the "Introduction" to this Offer to Purchase.

- - HOW MUCH ARE YOU OFFERING TO PAY, WHAT IS THE FORM OF PAYMENT AND WILL I HAVE
  TO PAY ANY FEES OR COMMISSIONS?

     We are offering to pay $45.00 per ordinary share, net to you, in cash,
without any interest, for each ordinary share. If you are the record owner of
your ordinary shares and you tender your ordinary shares to us in the offer, you
will not have to pay brokerage fees or similar expenses. If you own your
ordinary shares through a broker or other nominee, and your broker tenders your
ordinary shares 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 the "Introduction" to this Offer to Purchase.

- - DO YOU HAVE THE FINANCIAL RESOURCES TO MAKE PAYMENT?

     We will be provided with approximately $2.9 billion by our parent company,
Amerada Hess and/or its affiliates, which will be used to purchase all ordinary
shares validly tendered and not withdrawn in the offer and to provide funding
for payment for all ordinary shares transferred to us pursuant to a compulsory

                                        1
   5

acquisition under Section 88 of the Companies Law (2001 Second Revision) of the
Cayman Islands or pursuant to a scheme of arrangement in accordance with Section
86 of the Companies Law. This transfer of ordinary shares pursuant to a
compulsory acquisition or a scheme of arrangement will be conducted in
accordance with the terms and conditions of the acquisition agreement among us,
Amerada Hess and Triton. The offer is not conditioned on any financing
arrangements. Amerada Hess and/or its affiliates currently intend to provide us
with the funds necessary to purchase the ordinary shares through a combination
of loans and/or capital contributions. Amerada Hess and/or its affiliates intend
to obtain such funds through an existing credit facility and a new credit
facility for which it has received a financing commitment from Citibank, N.A.
and Salomon Smith Barney, Inc. See Section 9 -- "Source and Amount of Funds" in
this Offer to Purchase.

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

     We do not believe that our financial condition is relevant to your decision
whether to tender shares and accept the offer because:

     - the offer is being made for all ordinary shares, solely for cash,

     - the offer is not subject to any financing condition,

     - the form of payment that you will receive consists solely of cash and if
       you tender into the offer and receive payment in full for your ordinary
       shares, you will have no continuing equity interest in Triton, and

     - we may acquire all remaining ordinary shares for the same cash price
       pursuant to the compulsory acquisition or the scheme of arrangement, in
       each case in accordance with the Companies Law (2001 Second Revision) of
       the Cayman Islands and in the manner provided for in the acquisition
       agreement. See Section 11 -- "Purpose of the Offer; Plans for the
       Company; Certain Agreements" for a discussion of the requirements for
       effecting a compulsory acquisition or a scheme of arrangement in
       accordance with the Companies Law of the Cayman Islands.

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

     You will have until 12:00 midnight, New York City time, on Monday, August
13, 2001, to tender your ordinary shares in the offer, unless the offer is
extended pursuant to the terms of the acquisition agreement. Further, if you
cannot deliver everything that is required to make a valid tender by that time,
you may be able to use a guaranteed delivery procedure, which is described later
in this Offer to Purchase. See Section 1 -- "Terms of the Offer" and Section
3 -- "Procedures for Tendering Ordinary Shares" in this Offer to Purchase.

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

     Yes. Subject to the terms of the acquisition agreement, we have agreed with
Triton that we may extend the offer as required by any rule, regulation or
interpretation of the Securities and Exchange Commission or, if at the time the
offer is scheduled to expire, including at the end of an earlier extension, any
of the offer conditions is not satisfied or waived by us. We may extend the
offer for successive periods of up to ten business days at a time, or longer
periods as approved by Triton, until the earlier of the acceptance for payment
of any ordinary shares pursuant to the offer or September 15, 2001. In addition,
Triton may require us to extend the initial offering period on one occasion for
up to ten calendar days if the tender offer conditions have not been satisfied
or, even if the tender offer conditions have been satisfied, less than 90% of
the ordinary shares have been tendered into and not withdrawn from the offer.

     We may, or as described below, Triton may require us to, extend the
offering period on one occasion through a subsequent offering period for up to a
maximum of 20 business days as described below or if required by applicable law.
See Section 1 -- "Terms of the Offer" in this Offer to Purchase.

                                        2
   6

- - WILL THERE BE A SUBSEQUENT OFFERING PERIOD?

     A subsequent offering period, if one is included, will be an additional
period of time beginning after we have purchased ordinary shares tendered during
the initial offering period, during which holders of ordinary shares may tender
their ordinary shares and receive the offer consideration.

     We can make a subsequent offering period available for up to a maximum of
20 business days. Additionally, if we amend the minimum condition to a number of
ordinary shares representing at least a majority of the votes of the ordinary
shares on a fully diluted basis and accept any ordinary shares tendered and not
withdrawn for payment pursuant to the offer, then Triton can require us to make
a subsequent offering period available to the holders of ordinary shares by
extending the offer on one occasion, for up to a maximum of 20 business days.

     To comply with the applicable laws of the United States, during any
subsequent offering period we will immediately accept for payment all tenders of
ordinary shares and pay promptly for all ordinary shares tendered in any
subsequent offering period. No holders will have any withdrawal rights with
respect to ordinary shares tendered during any subsequent offering period. For
more information, see Section 1 -- "Terms of the Offer" in this Offer to
Purchase.

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

     If we extend the offer, we will inform The Bank of New York, which is the
depositary for the offer, of that fact. We also will make a public announcement
of the extension, not later than 9:00 a.m., New York City time, on the next
business day after the day on which the offer was scheduled to expire. See
Section 1 -- "Terms of the Offer" in this Offer to Purchase.

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

     - We are not obligated to purchase any ordinary shares which are validly
       tendered if the number of ordinary shares validly tendered and not
       properly withdrawn prior to the expiration of the offer represents less
       than 90% in value of the ordinary shares. We may, at any time, amend this
       minimum condition to equal the number of ordinary shares representing a
       majority of the total number of votes of the outstanding ordinary shares
       on a fully diluted basis. The amendment of the minimum condition as
       described above would require that we make adequate notice of such
       amendment and might require the extension of the offer.

     - We are not obligated to purchase any ordinary shares which are validly
       tendered if, among other things, the applicable waiting period under the
       Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, has not
       expired or been waived before we accept the shares which have been
       validly tendered.

     See the "Introduction" and Section 14 -- "Conditions of the Offer" in this
Offer to Purchase.

- - HOW DO I TENDER MY SHARES?

     To tender ordinary shares, you must deliver the certificate(s) representing
your ordinary shares, together with a completed Letter of Transmittal, to The
Bank of New York, the depositary for the offer, not later than the time the
tender offer expires. If your ordinary shares are held in "street name," the
ordinary shares can be tendered by your nominee through The Depository Trust
Company. If you cannot obtain any document or instrument that is required to be
delivered to the depositary by the expiration of the tender offer, you may
obtain a little extra time to do so by having a broker, a bank or other
fiduciary which is a member of the Securities Transfer Agents Medallion Program
or other eligible institution guarantee that the missing items will be received
by the depositary within three New York Stock Exchange trading days. For the
tender to be

                                        3
   7

valid, however, the depositary must receive the missing items within that three
trading day period. See Section 3 -- "Procedures for Tendering Ordinary Shares"
in this Offer to Purchase.

- - UNTIL WHAT TIME CAN I WITHDRAW PREVIOUSLY TENDERED SHARES?

     You can withdraw ordinary shares at any time until the offer (excluding any
subsequent offering period) has expired and, if we have not by September 14,
2001 agreed to accept your ordinary shares for payment, you can withdraw them at
any time after such time until we accept ordinary shares for payment. You may
not withdraw any ordinary shares tendered in a subsequent offering period. See
Section 1 -- "Terms of the Offer" and Section 4 -- "Withdrawal Rights" in this
Offer to Purchase.

- - HOW DO I WITHDRAW PREVIOUSLY TENDERED SHARES?

     To withdraw ordinary shares, you must deliver a written notice of
withdrawal, or a copy of one, with the required information to The Bank of New
York, the depositary for the offer, while you still have the right to withdraw
the ordinary shares. See Section 4 -- "Withdrawal Rights" in this Offer to
Purchase.

- - WHAT DOES THE TRITON BOARD OF DIRECTORS THINK OF THE OFFER?

     We are making the offer pursuant to an acquisition agreement among us,
Amerada Hess and Triton. The board of directors of Triton by unanimous vote has
determined that the acquisition agreement, the principal shareholders agreement
and the offer are fair to and in the best interests of the company and the
holders of the ordinary shares (other than, in the case of the transactions
contemplated by the principal shareholders agreement, the shareholders party
thereto). The board of directors of Triton by unanimous vote has approved the
execution, delivery and performance by Triton of the acquisition agreement and
the principal shareholders agreement by Triton and the consummation of the
transactions contemplated thereby, including the offer. The board of directors
of Triton has unanimously resolved to recommend that the holders of ordinary
shares accept the offer and tender their ordinary shares pursuant to the offer.
See the "Introduction" to this Offer to Purchase.

- - WILL WE SEEK TO ACQUIRE TRITON'S ENTIRE SHARE CAPITAL IF ALL OF TRITON'S
  ORDINARY SHARES ARE NOT TENDERED IN THE OFFER?

     Yes. If we accept for payment and pay for ordinary shares representing at
least 90% in value of the ordinary shares, both we and Triton will take all
necessary action to effect a compulsory acquisition of those ordinary shares not
owned by us and that are outstanding at the expiration of the offer, in
accordance with Section 88 of the Companies Law (2001 Second Revision) of the
Cayman Islands.

     If we are not required to take all necessary action to effect a compulsory
acquisition as described above, we may request that Triton take the actions
necessary to effectuate a scheme of arrangement pursuant to Sections 86 and 87
of the Companies Law of the Cayman Islands promptly following either (i) the
date we accept for payment ordinary shares of Triton and any subsequent offering
period expires or (ii) the date that the offer expires without the purchase of
any ordinary shares of Triton. We may only require Triton to take this action if
the offer has remained open for a minimum of 20 business days plus any extension
of the expiration date of the offer (up to ten days) required by Triton.

     If a compulsory acquisition takes place, we would acquire all remaining
ordinary shares of Triton (other than ordinary shares held by Amerada Hess or
its subsidiaries, including us) that are outstanding at the expiration of the
offer for $45.00 per ordinary share in cash and we will evaluate the best way in
which to acquire all preference shares that were not converted into ordinary
shares and tendered into the offer, which may include redeeming the preference
shares in accordance with their terms. If a scheme of arrangement is effected
pursuant to Sections 86 and 87 of the Companies Law, we will acquire all
remaining ordinary shares and, in the event that there are preference shares
outstanding on the commencement of the scheme of arrangement, preference shares
of Triton (other than shares held by Amerada Hess or its subsidiaries, including
us) for $45.00 per ordinary share in cash and $180.00, plus any accumulated and
unpaid dividends thereon, per preference share in cash. See the "Introduction"
to this Offer to Purchase.
                                        4
   8

- - IF A COMPULSORY ACQUISITION OR SCHEME OF ARRANGEMENT BECOMES EFFECTIVE, WILL
  TRITON CONTINUE AS A PUBLIC COMPANY?

     No. If we acquire Triton's entire share capital through the offer, a
compulsory acquisition or scheme of arrangement, Triton will no longer be
publicly owned. Even if neither a compulsory acquisition nor a scheme of
arrangement becomes effective, if we purchase all of the tendered ordinary
shares, there may be so few remaining holders of publicly held ordinary shares
that (a) Triton ordinary shares will no longer meet the published guidelines of
the New York Stock Exchange for continued listing and may be delisted from the
New York Stock Exchange, (b) there may not be a public trading market for Triton
ordinary shares, and (c) Triton may cease making filings with the Securities and
Exchange Commission or may not be required to comply with the Securities and
Exchange Commission rules relating to publicly held companies. See Section
13 -- "Effect of the Offer on the Market for the Shares; Exchange Act
Registration" in this Offer to Purchase.

- - IF I DECIDE NOT TO TENDER, HOW WILL THE OFFER AFFECT MY SHARES?

     If the compulsory acquisition takes place or the scheme of arrangement is
approved and becomes effective, shareholders not tendering in the offer will
receive the same amount of cash per ordinary share that they would have received
had they tendered their ordinary shares in the offer. Therefore, if the
compulsory acquisition takes place or the scheme of arrangement is approved and
becomes effective, the only difference to you between tendering your ordinary
shares and not tendering your ordinary shares is that you will be paid earlier
if you tender your ordinary shares. However, if a compulsory acquisition does
not take place and a scheme of arrangement does not become effective, there may
be so few remaining holders of ordinary shares that there may not be any active
public trading market for the ordinary shares and the delisting or
deregistration described above may occur. See the "Introduction" and Section
13 -- "Effect of the Offer on the Market for the Shares; Exchange Act
Registration" of this Offer to Purchase.

- - WHAT IS THE MARKET VALUE OF MY ORDINARY SHARES AS OF A RECENT DATE?

     The $45.00 per ordinary share offer price represents a 50% premium over the
last sale price of $29.90 per share for Triton ordinary shares reported on the
New York Stock Exchange on July 9, 2001, the last trading day before we
announced the transaction. We advise you to obtain historical and recent
quotations for ordinary shares of Triton in deciding whether to tender your
ordinary shares. See Section 6 -- "Price Range of Ordinary Shares; Dividends" in
this Offer to Purchase.

- - WHAT IF I ALSO OWN PREFERENCE SHARES TO PURCHASE ORDINARY SHARES?

     The offer is only being made for the ordinary shares of Triton. If you own
preference shares and would like to participate in the offer you will first need
to arrange for the conversion of your preference shares into ordinary shares
before tendering them into the offer. Alternatively, we have been informed that
the Company intends to make available to holders of preference shares the
opportunity to surrender their preference shares for conversion into ordinary
shares conditional on our acceptance of ordinary shares for payment pursuant to
the offer. Holders of preferred shares will be contacted separately regarding
the procedures to be followed to conditionally convert their preference shares
and tender the ordinary shares issued upon such conversion.

To the Holders of Ordinary Shares of Triton Energy Limited:

                                  INTRODUCTION

     Amerada Hess (Cayman) Limited (the "Purchaser"), a company limited by
shares, organized under the laws of the Cayman Islands and a wholly owned
subsidiary of Amerada Hess Corporation ("Amerada Hess"), a Delaware corporation,
hereby offers to purchase all of the existing unconditionally allotted or issued
and fully paid ordinary shares, par value $0.01 per share, of Triton Energy
Limited (the "Company"), a company limited by shares organized under the laws of
the Cayman Islands, and any further ordinary shares which are unconditionally
allotted or issued and fully paid before the date and time on which the Offer
(as defined below) expires, including the associated Rights (as defined below)
(the "Ordinary Shares"), at a price of $45.00 per Ordinary Share, net to the
seller in cash, without interest thereon (the "Ordinary Share Offer Price"), on
the terms and subject to the conditions set forth in this Offer to Purchase and
in the related Letter of Transmittal (which, as they may be amended and
supplemented from time to time, together constitute the "Offer").

     Unless the context indicates otherwise, all references to Ordinary Shares
shall include the associated Series A junior participating preferred share
purchase rights (the "Rights") issued pursuant to the Rights Agreement (the
"Rights Agreement"), dated as of March 25, 1996, as amended, by and between the
Company and Mellon Investor Services LLC ("Mellon") (as successor to Chemical
Bank), as Rights Agent (the "Rights Agent"). To validly tender Ordinary Shares,
a holder must tender the Rights. Unless a Distribution Date (as defined below)
has occurred, the tender of Ordinary Shares will constitute the tender of the
associated Rights.

     Holders of Ordinary Shares ("Holders") whose Ordinary Shares are registered
in their own name and who tender directly to The Bank of New York, as Depositary
(the "Depositary") will not be obligated to pay brokerage fees or commissions
or, except as set forth in Instruction 6 of the Letter of Transmittal, transfer
taxes on the purchase of Ordinary Shares pursuant to the Offer. The Purchaser
will pay all charges and expenses of Goldman, Sachs & Co., as Dealer Managers
(the "Dealer Managers"), the Depositary and D.F. King & Co., Inc., as
Information Agent (the "Information Agent"), in each case incurred in connection
with the Offer. See Section 16 -- "Fees and Expenses."

     THE OFFER IS CONDITIONED ON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT PROPERLY WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER A
NUMBER OF ORDINARY SHARES WHICH REPRESENT AT LEAST 90% IN VALUE OF THE ORDINARY
SHARES (THE "MINIMUM CONDITION"). FOR PURPOSES OF DETERMINING WHETHER SUCH
MINIMUM CONDITION IS SATISFIED, ALL ORDINARY SHARES HELD BY THE PRINCIPAL
SHAREHOLDERS (AS DEFINED BELOW) THAT ARE TENDERED AND NOT WITHDRAWN (BUT
CONTINUING TO INCLUDE FOR SUCH PURPOSE ALL ORDINARY SHARES WITHDRAWN AT THE
INSTRUCTION OF AMERADA HESS) AND ALL ORDINARY SHARES ISSUABLE UPON CONVERSION OF
PREFERRED SHARES THAT ARE SURRENDERED FOR CONVERSION BY THE PRINCIPAL
SHAREHOLDERS WITH APPROPRIATE TENDER INSTRUCTIONS PURSUANT TO THE PRINCIPAL
SHAREHOLDERS AGREEMENT (AS DEFINED BELOW) (BUT CONTINUING TO INCLUDE FOR SUCH
PURPOSE ALL ORDINARY SHARES ISSUABLE UPON CONVERSION OF PREFERRED SHARES WITH
RESPECT TO WHICH TENDER AND CONVERSION INSTRUCTIONS ARE REVOKED AT THE
INSTRUCTION OF AMERADA HESS) SHALL BE INCLUDED IN SUCH CALCULATION. AMERADA HESS
OR THE PURCHASER MAY, AT ANY TIME, AMEND THE MINIMUM CONDITION TO EQUAL THE
NUMBER OF ORDINARY SHARES REPRESENTING AT LEAST A MAJORITY OF THE TOTAL NUMBER
OF VOTES OF THE ORDINARY SHARES DETERMINED ON A FULLY DILUTED BASIS ("ON A FULLY
DILUTED BASIS" MEANING, AT ANY TIME, THE NUMBER OF ORDINARY SHARES ALLOTTED AND
ISSUED, TOGETHER WITH THE ORDINARY SHARES WHICH THE COMPANY MAY BE REQUIRED TO
ISSUE, NOW OR IN THE FUTURE, INCLUDING, WITHOUT LIMITATION, ORDINARY SHARES
ISSUABLE PURSUANT TO WARRANTS, OPTIONS OR OTHER RIGHTS OR OTHER OBLIGATIONS
OUTSTANDING AT SUCH TIME UNDER EMPLOYEE STOCK OR SIMILAR BENEFIT PLANS OR
OTHERWISE, WHETHER OR NOT VESTED OR THEN EXERCISABLE, BUT EXCLUDING THE EFFECT
OF THE RIGHTS). THE AMENDMENT OF THE MINIMUM CONDITION AS DESCRIBED ABOVE WOULD
REQUIRE ADEQUATE NOTICE OF SUCH AMENDMENT TO HOLDERS AND MIGHT REQUIRE AN
EXTENSION OF THE OFFER. THE OFFER IS ALSO CONDITIONED ON THE SATISFACTION OF THE
HSR CONDITION (AS DEFINED BELOW) AND THE SATISFACTION OF CERTAIN OTHER TERMS AND
CONDITIONS DESCRIBED IN SECTION 14 -- "CONDITIONS OF THE OFFER."

     "HSR CONDITION" MEANS THE EXPIRATION OR TERMINATION OF ANY APPLICABLE
WAITING PERIOD UNDER THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976,
AS AMENDED, AND THE RULES AND REGULATIONS THEREUNDER
                                        6
   10

(THE "HSR ACT"). SEE SECTION 14 -- "CONDITIONS OF THE OFFER" FOR A COMPLETE
DESCRIPTION OF THE CONDITIONS OF THE OFFER.

     AMERADA HESS AND THE PURCHASER HAVE ENTERED INTO A PRINCIPAL SHAREHOLDERS
AGREEMENT (THE "PRINCIPAL SHAREHOLDERS AGREEMENT") DATED AS OF JULY 9, 2001 WITH
THE COMPANY, HM4 TRITON, L.P., AN AFFILIATE OF HICKS, MUSE, TATE & FURST
INCORPORATED ("HICKS MUSE"), AND CERTAIN OTHER SHAREHOLDERS OF THE COMPANY (THE
"PRINCIPAL SHAREHOLDERS"). THE PRINCIPAL SHAREHOLDERS BENEFICIALLY OWN, IN THE
AGGREGATE, 1,733,573 ORDINARY SHARES AND 5,058,685 PREFERRED SHARES. EACH
PREFERRED SHARE IS CONVERTIBLE INTO FOUR ORDINARY SHARES. THE ORDINARY SHARES
AND THE PREFERRED SHARES BENEFICIALLY OWNED BY THE PRINCIPAL SHAREHOLDERS
REPRESENT APPROXIMATELY 37.7% OF THE ALLOTTED AND ISSUED ORDINARY SHARES,
ASSUMING CONVERSION OF SUCH PREFERRED SHARES (34.2% ON A FULLY DILUTED BASIS).
THE PRINCIPAL SHAREHOLDERS HAVE AGREED TO TENDER PURSUANT TO THE OFFER THEIR
ORDINARY SHARES AND TO CONDITIONALLY CONVERT THEIR PREFERRED SHARES AND
CONDITIONALLY TENDER PURSUANT TO THE OFFER THE ORDINARY SHARES INTO WHICH THE
PREFERRED SHARES ARE CONVERTIBLE. THE ACQUISITION AGREEMENT REQUIRES THE
PURCHASER TO ACCEPT FOR PAYMENT AND PAY FOR ALL ORDINARY SHARES OWNED BY THE
PRINCIPAL SHAREHOLDERS AND ALL ORDINARY SHARES ISSUABLE UPON CONVERSION OF THE
PREFERRED SHARES OWNED BY THE PRINCIPAL SHAREHOLDERS IF THE PURCHASER ACCEPTS
FOR PAYMENT ANY ORDINARY SHARES PURSUANT TO THE OFFER. IF THE ORDINARY SHARES
BENEFICIALLY OWNED BY THE PRINCIPAL SHAREHOLDERS (INCLUDING ORDINARY SHARES
ISSUABLE UPON THE CONDITIONAL CONVERSION AND TENDER OF THE PREFERRED SHARES) ARE
NOT PURCHASED PURSUANT TO THE OFFER (EXCLUDING FOR THIS PURPOSE ANY SUBSEQUENT
OFFERING PERIOD (AS DEFINED BELOW)), THE PURCHASER WILL PURCHASE THE ORDINARY
SHARES AND THE PREFERRED SHARES BENEFICIALLY OWNED BY THE PRINCIPAL SHAREHOLDERS
FOLLOWING THE EXPIRATION OF THE INITIAL OFFERING PERIOD (INCLUDING ANY EXTENSION
THEREOF). THE PURCHASE PRICE FOR THE ORDINARY SHARES WOULD BE $45.00 PER SHARE
IN CASH AND THE PURCHASE PRICE FOR THE PREFERRED SHARES WOULD BE $180.00 PER
SHARE, PLUS ANY ACCUMULATED AND UNPAID DIVIDENDS THEREON, IN CASH.

     THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY (I) DETERMINED THAT
THE ACQUISITION AGREEMENT (AS DEFINED BELOW), THE PRINCIPAL SHAREHOLDERS
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER, THE
SCHEME OF ARRANGEMENT (AS DEFINED BELOW) AND THE COMPULSORY ACQUISITION (AS
DEFINED BELOW) ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY AND THE
HOLDERS OF ORDINARY SHARES AND PREFERRED SHARES (OTHER THAN, IN THE CASE OF
TRANSACTIONS CONTEMPLATED BY THE PRINCIPAL SHAREHOLDERS AGREEMENT, THE PRINCIPAL
SHAREHOLDERS), (II) APPROVED THE EXECUTION, DELIVERY AND PERFORMANCE BY THE
COMPANY OF THE ACQUISITION AGREEMENT AND THE PRINCIPAL SHAREHOLDERS AGREEMENT
AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER, THE SCHEME OF
ARRANGEMENT AND THE COMPULSORY ACQUISITION, AND (III) RESOLVED TO RECOMMEND THAT
THE HOLDERS ACCEPT THE OFFER AND TENDER THEIR ORDINARY SHARES (INCLUDING THE
RIGHTS) PURSUANT TO THE OFFER AND THAT THE HOLDERS OF ORDINARY SHARES AND
PREFERRED SHARES APPROVE THE SCHEME OF ARRANGEMENT, IF SUCH APPROVAL IS SOUGHT.

     THE COMPANY HAS ADVISED AMERADA HESS THAT J.P. MORGAN SECURITIES INC., THE
FINANCIAL ADVISOR TO THE COMPANY, HAS DELIVERED TO THE BOARD OF DIRECTORS OF THE
COMPANY ITS OPINION DATED JULY 9, 2001, THAT, AS OF THE DATE OF THE ACQUISITION
AGREEMENT, THE CONSIDERATION TO BE RECEIVED IN THE OFFER AND EITHER THE PROPOSED
COMPULSORY ACQUISITION OR THE PROPOSED SCHEME OF ARRANGEMENT, AS APPLICABLE, BY
THE HOLDERS OF ORDINARY SHARES AND THE HOLDERS OF THE PREFERRED SHARES (OTHER
THAN AMERADA HESS OR ANY DIRECT OR INDIRECT SUBSIDIARY THEREOF) IS FAIR, FROM A
FINANCIAL POINT OF VIEW, TO SUCH HOLDERS (OTHER THAN, IN THE CASE OF THE
TRANSACTIONS CONTEMPLATED BY THE PRINCIPAL SHAREHOLDERS AGREEMENT, THE PRINCIPAL
SHAREHOLDERS), SUBJECT TO THE ASSUMPTIONS AND QUALIFICATIONS SET FORTH THEREIN.
A COPY OF THE OPINION OF J.P. MORGAN SECURITIES INC., WHICH SETS FORTH THE
ASSUMPTIONS MADE, FACTORS CONSIDERED AND SCOPE OF REVIEW UNDERTAKEN BY J.P.
MORGAN SECURITIES INC., IS CONTAINED IN THE COMPANY'S
SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 (THE "SCHEDULE 14D-9"),
WHICH IS BEING MAILED TO THE HOLDERS CONCURRENTLY HEREWITH. HOLDERS ARE URGED TO
READ THE FULL TEXT OF THAT OPINION.

     The Offer is being made pursuant to an Acquisition Agreement (the
"Acquisition Agreement"), dated as of July 9, 2001, as amended, by and among
Amerada Hess, the Purchaser and the Company. The Acquisition Agreement provides
that, in the event that, following the purchase of Ordinary Shares pursuant to
the Offer (including any Subsequent Offering Period), Amerada Hess, the
Purchaser and any other subsidiary of Amerada Hess shall own Ordinary Shares
which represent at least 90% in value of the Ordinary Shares, the Company,
Amerada Hess and the Purchaser agree to take all necessary and appropriate
action for the
                                        7
   11

Purchaser to effect the compulsory acquisition (the "Compulsory Acquisition") of
those Ordinary Shares that are not owned by Amerada Hess, the Purchaser or any
other subsidiary of Amerada Hess in accordance with Section 88 of the Companies
Law (2001 Second Revision) of the Cayman Islands (the "Companies Law") as
promptly as practicable after the acceptance for payment of Ordinary Shares
pursuant to the Offer. See Section 11 -- "Purpose of the Offer; Plans for the
Company; Certain Agreements."

     Promptly following the acceptance for payment of Ordinary Shares pursuant
to the Offer and, if applicable, the Subsequent Offering Period which results in
Amerada Hess, the Purchaser and any other subsidiary of Amerada Hess owning
Ordinary Shares which represent less than 90% in value of the Ordinary Shares,
or the expiration of the Offer without the purchase of any Ordinary Shares
thereunder, (A) if the Offer has remained open for a minimum of 20 business
days, plus any extension of the Expiration Date (as defined below) (up to an
additional ten days) that has been required by the Company, and (B) if requested
by Amerada Hess or the Purchaser, in their sole discretion and in accordance
with applicable law, the Company shall (i) cause an application to be made to
the Grand Court of the Cayman Islands (the "Court") requesting the Court to
summon such class meetings of shareholders of the Company as the Court may
direct ("Shareholders' Meetings"), (ii) if directed by the Court, convene such
Shareholders' Meetings seeking the approval required under Section 86(2) of the
Companies Law and (iii) subject to such approvals being obtained, cause a
petition to be presented to the Court seeking the sanctioning of a scheme of
arrangement pursuant to Section 86 of the Companies Law (the "Scheme of
Arrangement") and file such other documents as are required to be duly filed
with the Court to effect the Scheme of Arrangement. Upon the Company having
caused a copy of the order of the Court sanctioning the Scheme of Arrangement to
be duly delivered to the Registrar of Companies of the Cayman Islands (the
"Registrar") and the registration of such order by the Registrar (the "Scheme
Effective Time"), by virtue of the Scheme of Arrangement: (i) each Ordinary
Share (and the associated Rights) issued and outstanding immediately prior to
the Scheme Effective Time (other than Ordinary Shares (and the associated
Rights) which are held by any wholly owned subsidiary of the Company, or which
are held, directly or indirectly, by Amerada Hess or any subsidiary of Amerada
Hess (including the Purchaser)) shall be, by virtue of the Scheme of Arrangement
and without any action required by the Holder thereof, transferred to the
Purchaser in consideration for $45.00 in cash per Ordinary Share transferred;
and (ii) in the event that there are Preferred Shares outstanding on the
commencement of the Scheme of Arrangement, each Preferred Share issued and
outstanding immediately prior to the Scheme Effective Time (other than Preferred
Shares which are held by any wholly owned subsidiary of the Company, or which
are held, directly or indirectly, by Amerada Hess or any subsidiary of Amerada
Hess (including the Purchaser)) shall be, by virtue of the Scheme of Arrangement
and without any action required by the holder thereof, transferred to the
Purchaser in consideration for $180.00, plus any accumulated and unpaid
dividends thereon through the Scheme Effective Date, in cash per Preferred
Share. See Section 11 -- "Purpose of the Offer; Plans for the Company; Certain
Agreements."

     The Company has informed the Purchaser that, as of July 5, 2001, there were
(i) 37,500,375 Ordinary Shares outstanding, (ii) 5,180,265 Preferred Shares
outstanding, (iii) no Series A junior participating preference shares
outstanding, (iv) no Ordinary Shares and no Preferred Shares held in the
Company's treasury and (v) stock options and other rights issued and
outstanding, representing in the aggregate the right to purchase 6,013,818
Ordinary Shares. Based on the foregoing numbers and assuming the conversion of
all of the Preferred Shares and the tender of all of the Ordinary Shares
resulting from such conversion and the exercise of all options and the tender of
all of the Ordinary Shares resulting from the exercise of such options, the
Minimum Condition would be satisfied if 57,811,728 Ordinary Shares are validly
tendered and not properly withdrawn prior to the Expiration Date. As the
Principal Shareholders beneficially own 21,968,313 Ordinary Shares (assuming
full conversion of Preferred Shares beneficially owned by the Principal
Shareholders), based on the same information and assumptions, the Minimum
Condition would be satisfied if 35,843,415 Ordinary Shares are validly tendered
and not properly withdrawn by Holders other than the Principal Shareholders
prior to the Expiration Date.

     The Company has been advised, and has informed Amerada Hess, that each of
its directors and executive officers intends to tender pursuant to the Offer all
Ordinary Shares owned of record and beneficially by him or

                                        8
   12

her, except to the extent that such tender would violate applicable securities
laws or require disgorgement of profits from any such tender offer under Section
16 of the Exchange Act (as defined below).

     THIS OFFER TO PURCHASE AND THE LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.

                                THE TENDER OFFER

     1.  TERMS OF THE OFFER.  On the terms and subject to the conditions of the
Offer (including, if the Offer is extended or amended, the terms and conditions
of any extension or amendment), the Purchaser will accept for payment and pay
for all Ordinary Shares validly tendered prior to the Expiration Date and not
properly withdrawn in accordance with Section 4 -- "Withdrawal Rights." The term
"Expiration Date" means 12:00 midnight, New York City time, on Monday, August
13, 2001, unless and until the Purchaser, in its sole discretion or at the
direction of the Company (subject to the terms of the Acquisition Agreement),
shall have extended the period of time during which the Offer is open, in which
event the term "Expiration Date" shall mean the latest time and date at which
the Offer, as so extended by the Purchaser, shall expire.

     The Offer is conditioned on, among other things, satisfaction of the
Minimum Condition and the HSR Condition. The Offer is also subject to certain
other conditions set forth in Section 14 -- "Conditions of the Offer." If these
or any of the other conditions referred to in Section 14 -- "Conditions of the
Offer" are not satisfied or any of the events specified in Section
14 -- "Conditions of the Offer" have occurred or are determined by the Purchaser
to have occurred prior to the Expiration Date, the Purchaser, subject to the
terms of the Acquisition Agreement and the limitations described below,
expressly reserves the right (but is not obligated) to (i) decline to purchase
any of the Ordinary Shares tendered in the Offer and terminate the Offer, and
return all tendered Ordinary Shares to the tendering Holders, (ii) waive or
amend any or all conditions to the Offer and, to the extent permitted by the
Acquisition Agreement or applicable law and applicable rules and regulations of
the Securities and Exchange Commission (the "Commission"), purchase all Ordinary
Shares validly tendered or (iii) extend the Offer and, subject to the right of a
tendering Holder to withdraw its Ordinary Shares until the Expiration Date,
retain the Ordinary Shares which have been tendered during the period or periods
for which the Offer is extended.

     The Rights are currently evidenced by the certificates for the Ordinary
Shares and the tender by a Holder of such Holder's Ordinary Shares will also
constitute a tender of the associated Rights. Pursuant to the Offer, no separate
payment will be made by the Purchaser for the Rights.

     Subject to the terms of the Acquisition Agreement described below, the
applicable rules and regulations of the Commission and applicable law, the
Purchaser expressly reserves the right, in its sole discretion, at any time and
from time to time, to extend for any reason the period of time during which the
Offer is open, including upon the occurrence of any of the events specified in
Section 14 -- "Conditions of the Offer," by giving notice of such extension to
the Depositary and by making a public announcement thereof not later than 9:00
a.m. New York City time, on the next business day after the day on which the
Offer was scheduled to expire. The Company also may require the Purchaser to
extend the initial offering period on one occasion for up to ten calendar days
if, at the scheduled expiration date of the Offer, the tender offer conditions
have not been satisfied or, even if the tender offer conditions have been
satisfied, less than 90% in value of the Ordinary Shares have been tendered into
and not withdrawn from the Offer. Except as may be required pursuant to the
Acquisition Agreement, there can be no assurance that the Purchaser or the
Company will exercise its right to extend the Offer. During any such extension,
all Ordinary Shares previously tendered and not withdrawn will remain subject to
the Offer, subject to the rights of a tendering Holder to withdraw its Ordinary
Shares. See Section 4 -- "Withdrawal Rights."

     Subject to the terms of the Acquisition Agreement described below, the
applicable rules and regulations of the Commission and to applicable law, the
Purchaser also expressly reserves the right, in its sole discretion, at any time
and from time to time (i) to delay acceptance for payment of, or, regardless of
whether such Ordinary Shares were theretofore accepted for payment, payment for,
any Ordinary Shares if any applicable waiting period under the HSR Act has not
expired or been terminated, (ii) to terminate the Offer on any

                                        9
   13

scheduled Expiration Date and not accept for payment any Ordinary Shares if any
of the conditions referred to in Section 14 -- "Conditions of the Offer" are not
satisfied or any of the events specified in Section 14 -- "Conditions of the
Offer" have occurred and (iii) to waive any condition or otherwise amend the
Offer in any respect (subject to the limitations described below) by giving oral
or written notice of such delay, termination, waiver or amendment to the
Depositary and by making a public announcement thereof.

     The Purchaser expressly reserves the right to modify the terms of the
Offer, provided, however, that the Purchaser shall not (and Amerada Hess shall
cause the Purchaser not to), without the prior written consent of the Company,
(i) reduce the number of Ordinary Shares to be purchased pursuant to the Offer,
(ii) reduce the Ordinary Share Offer Price, (iii) impose any additional
conditions to the Offer, (iv) change the form of consideration payable in the
Offer, (v) make any change to the terms of the Offer, including without
limitation the tender offer conditions, which is materially adverse in any
manner to the Holders, (vi) amend or waive the Minimum Condition, except that
the Purchaser may, at any time, amend the Minimum Condition to equal the number
of Ordinary Shares representing a majority of the total number of votes of the
outstanding Ordinary Shares determined on a fully diluted basis or (vii) extend
the Expiration Date, provided, however, that Amerada Hess or the Purchaser may
extend the Expiration Date: (A) as required by any rule, regulation or
interpretation of the Commission; or (B) in the event that any condition to the
Offer is not satisfied and, to the extent permitted in the Acquisition
Agreement, is not waived as of the scheduled Expiration Date, for such
successive periods for up to ten business days at a time (or such longer period
as shall be approved by the Company) until the earlier of the acceptance for
payment of any Ordinary Shares pursuant to the Offer or September 15, 2001.
Notwithstanding anything in the foregoing to the contrary, the Company may
require the Purchaser to extend the offer on one occasion for a maximum period
of ten days if at the scheduled Expiration Date, the tender offer conditions
(assuming for this purpose that the Minimum Condition has not been amended as
contemplated in clause (vi) of the preceding sentence) have not been satisfied.

     The Purchaser acknowledges that (i) Rule 14e-1(c) under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), requires the Purchaser to
pay the consideration offered or return the Ordinary Shares tendered promptly
after the termination or withdrawal of the Offer and (ii) the Purchaser may not
delay acceptance for payment of, or payment for (except as provided in clause
(i) of the second preceding paragraph), any Ordinary Shares upon the occurrence
of any of the conditions specified in Section 14 -- "Conditions of the Offer"
without extending the period of time during which the Offer is open. During any
such extension, all Ordinary Shares previously tendered and not properly
withdrawn will remain subject to the Offer, subject to the right of a tendering
Holder to withdraw its Ordinary Shares.

     Pursuant to Rule 14d-11 under the Exchange Act, the Purchaser, subject to
certain conditions, may make available a subsequent offering period (the
"Subsequent Offering Period") by extending the Offer on one occasion for a
period of not less than three business days and not to exceed 20 business days.
Additionally, Amerada Hess, the Purchaser and the Company have agreed that (i)
the Purchaser may include a Subsequent Offering Period for up to a maximum of 20
business days and (ii) the Company may require the Purchaser to make a
Subsequent Offering Period available to the Holders by extending the offer on
one occasion for up to a maximum of 20 business days, if the Purchaser amends
the Minimum Condition as contemplated in clause (vi) of the first sentence of
the second preceding paragraph and accepts Ordinary Shares tendered and not
withdrawn for payment pursuant to the terms of the Offer.

     If the Purchaser commences a Subsequent Offering Period, U.S. federal
securities laws require the Purchaser to accept immediately for payment all
tenders of Ordinary Shares during a Subsequent Offering Period and to pay
promptly for all Ordinary Shares tendered in any Subsequent Offering Period.

     During a Subsequent Offering Period, tendering Holders will not have
withdrawal rights and the Purchaser will promptly accept and pay for all
Ordinary Shares tendered at the same price paid in the Offer. Rule 14d-11
provides that the Purchaser may provide a Subsequent Offering Period so long as,
among other things, (i) the initial 20 business day period of the Offer has
expired, (ii) the offer is for all outstanding securities of the class that is
the subject of the Offer, (iii) the Purchaser accepts and promptly pays for all
Ordinary Shares tendered during the Offer prior to its expiration, (iv) the
Purchaser announces the results of the Offer, including the approximate number
and percentage of Ordinary Shares deposited in the Offer, no

                                        10
   14

later than 9:00 a.m. New York City time on the next business day after the
Expiration Date and immediately begins the Subsequent Offering Period, (v) the
Purchaser immediately accepts and promptly pays for Ordinary Shares as they are
tendered during the Subsequent Offering Period and (vi) the Purchaser offers the
same form and amount of consideration for Ordinary Shares in the Subsequent
Offering Period as in the Offer. The staff of the Commission has expressed the
view that a bidder can decide to provide for a Subsequent Offering Period after
the initial offering period has expired if such a Subsequent Offering Period is
announced at the same time that the bidder announces the results of the initial
offering period. In the event the Purchaser elects to include a Subsequent
Offering Period, it will notify Holders consistent with the requirements of the
Commission.

     THE PURCHASER MAY INCLUDE A SUBSEQUENT OFFERING PERIOD IN THE OFFER IN THE
CIRCUMSTANCES SET FORTH ABOVE. PURSUANT TO RULE 14d-7 UNDER THE EXCHANGE ACT, NO
WITHDRAWAL RIGHTS APPLY TO ORDINARY SHARES TENDERED DURING A SUBSEQUENT OFFERING
PERIOD WITH RESPECT TO ORDINARY SHARES TENDERED IN THE OFFER AND ACCEPTED FOR
PAYMENT. THE SAME CONSIDERATION, THE ORDINARY SHARE OFFER PRICE, WILL BE PAID TO
HOLDERS TENDERING ORDINARY SHARES IN THE OFFER OR IN A SUBSEQUENT OFFERING
PERIOD, IF ONE IS INCLUDED.

     Any extension, delay, termination, waiver or amendment described below will
be followed, as promptly as practicable, by public announcement thereof, with
such announcement in the case of an extension to be made no later than 9:00
a.m., New York City time, on the next business day after the previously
scheduled Expiration Date. Subject to applicable law (including Rules 14d-4(c),
14d-6(c) and 14e-1 under the Exchange Act, which require that material changes
be promptly disseminated to Holders in a manner reasonably designed to inform
them of such changes) and without limiting the manner in which the Purchaser may
choose to make any public announcement, the Purchaser will have no obligation to
publish, advertise or otherwise communicate any such public announcement other
than by issuing a press release to the Dow Jones News Service or as otherwise
may be required by applicable law.

     If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, or if it waives a material condition of the
Offer, the Purchaser will 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 the Offer must remain open following material changes in the terms of the
Offer or information concerning the Offer, other than a change in price or a
change in the percentage of Ordinary Shares sought, will depend upon the facts
and circumstances then existing, including the relative materiality of the
changed terms or information. With respect to a change in price or a change in
the percentage of Ordinary Shares sought, a minimum period of ten business days
is generally required to allow for adequate dissemination to Holders and
investor response. The amendment of the Minimum Condition, as described above,
would require that adequate notice of such amendment be provided to Holders and
might require an extension of the Offer.

     The Company has provided the Purchaser with the Company's shareholder lists
and security position listings in respect of the Ordinary Shares for the purpose
of disseminating the Offer to Purchase, the Letter of Transmittal and other
relevant materials to Holders. This Offer to Purchase, the Letter of Transmittal
and other relevant materials will be mailed to record Holders whose names appear
on the Company's list of Holders and will be furnished, for subsequent
transmittal to beneficial owners of Ordinary Shares, to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the names
of whose nominees, appear on the Company's list of Holders or, where applicable,
who are listed as participants in the security position listing of The
Depository Trust Company ("DTC").

     2.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR ORDINARY SHARES.  On the terms
and subject to the conditions of the Offer (including, if the Offer is extended
or amended, the terms and conditions of any such extension or amendment), the
Acquisition Agreement and applicable law (including Rule 14e-1(c) under the
Exchange Act), the Purchaser will purchase, by accepting for payment, and will
pay for, all Ordinary Shares validly tendered prior to the Expiration Date (and
not properly withdrawn in accordance with Section 4 -- "Withdrawal Rights")
promptly after the later to occur of (i) the Expiration Date and (ii) the
satisfaction or waiver of the conditions set forth in Section 14 -- "Conditions
of the Offer," including, but not limited to, the regulatory conditions
specified in Section 15 -- "Certain Legal Matters; Regulatory Approvals."
Subject to applicable rules of the Commission and the terms of the Acquisition
Agreement, the Purchaser expressly

                                        11
   15

reserves the right, in its sole discretion, to delay acceptance for payment of,
or payment for, Ordinary Shares in order to comply, in whole or in part, with
any applicable law. If, following acceptance for payment of Ordinary Shares, the
Purchaser asserts such regulatory approvals as a condition and does not promptly
pay for Ordinary Shares tendered, the Purchaser will promptly return such
Ordinary Shares.

     In all cases, payment for Ordinary Shares purchased pursuant to the Offer
will be made only after timely receipt by the Depositary of (i) the certificates
evidencing such Ordinary Shares (the "Certificates") or timely confirmation of a
book-entry transfer (a "Book-Entry Confirmation") of such Ordinary Shares into
the Depositary's account at DTC (the "Book-Entry Transfer Facility"), pursuant
to the procedures set forth in Section 3 -- "Procedures for Tendering Ordinary
Shares," (ii) the Letter of Transmittal (or a copy thereof), properly completed
and duly executed with any required signature guarantees, or an Agent's Message
(as defined below) in connection with a book-entry transfer and (iii) any other
documents required to be included with the Letter of Transmittal under the terms
and subject to the conditions thereof and to this Offer to Purchase.

     The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary forming a part of a
Book-Entry Confirmation system, which states that the Book-Entry Transfer
Facility has received an express acknowledgment from a participant in the
Book-Entry Transfer Facility tendering the Ordinary Shares that such participant
has received and agrees to be bound by the terms of the Letter of Transmittal
and that the Purchaser may enforce such agreement against such participant.

     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment (and thereby purchased) Ordinary Shares validly tendered and not
properly withdrawn if, as and when the Purchaser gives oral or written notice to
the Depositary of the Purchaser's acceptance for payment of such Ordinary
Shares. On the terms and subject to the conditions of the Offer, payment for
Ordinary Shares accepted pursuant to the Offer will be made by deposit of the
purchase price therefor with the Depositary within three business days after
acceptance for payment of Ordinary Shares tendered pursuant to the Offer, which
will act as agent for tendering Holders for the purpose of receiving payments
from the Purchaser and transmitting payments to such tendering Holders whose
Ordinary Shares have been accepted for payment. UNDER NO CIRCUMSTANCES WILL
INTEREST ON THE ORDINARY SHARE OFFER PRICE BE PAID BY THE PURCHASER, REGARDLESS
OF ANY DELAY IN MAKING SUCH PAYMENT OR EXTENSION OF THE EXPIRATION DATE. Upon
the deposit of funds with the Depositary for the purpose of making payments to
tendering Holders, the Purchaser's obligation to make such payment shall be
satisfied, and tendering Holders must thereafter look solely to the Depositary
for payment of amounts owed to them by reason of the acceptance for payment of
Ordinary Shares pursuant to the Offer.

     If any tendered Ordinary Shares are not accepted for payment for any reason
pursuant to the terms and conditions of the Offer, or if Certificates are
submitted evidencing more Ordinary Shares than are tendered, Certificates
evidencing Ordinary Shares not purchased will be returned, without expense to
the tendering Holder (or, in the case of Ordinary Shares tendered by book-entry
transfer into the Depositary's account at the Book-Entry Transfer Facility
pursuant to the procedure set forth in Section 3 -- "Procedures for Tendering
Ordinary Shares," such Ordinary Shares will be credited to an account maintained
at the Book-Entry Transfer Facility), as promptly as practicable following the
expiration or termination of the Offer.

     If, prior to the Expiration Date, the Purchaser increases the consideration
to be paid per Ordinary Share pursuant to the Offer, the Purchaser will pay such
increased consideration for all such Ordinary Shares purchased pursuant to the
Offer, whether or not such Ordinary Shares were tendered prior to such increase
in consideration.

     The Purchaser reserves the right to assign to Amerada Hess, or to any other
direct or indirect wholly owned subsidiary of Amerada Hess, the right to
purchase all or any portion of the Ordinary Shares tendered pursuant to the
Offer, but any such assignment will not relieve the Purchaser of its obligations
under the Offer and the Acquisition Agreement and will in no way prejudice the
rights of tendering Holders to receive payment for Ordinary Shares validly
tendered and accepted for payment pursuant to the Offer.

     3.  PROCEDURES FOR TENDERING ORDINARY SHARES.

     VALID TENDER OF ORDINARY SHARES.  In order for Ordinary Shares to be
validly tendered pursuant to the Offer, a Holder must, prior to the Expiration
Date, either (i) deliver to the Depositary at one of its addresses set forth on
the back cover of this Offer to Purchase (a) a properly completed and duly
executed Letter of Transmittal (or a copy thereof) with any required signature
guarantees, (b) the Certificates to be tendered and (c) any other documents
required to be included with the Letter of Transmittal under the terms and
subject to the conditions thereof and of this Offer to Purchase, (ii) cause such
Holder's broker, dealer, commercial bank, trust company or custodian to tender
applicable Ordinary Shares pursuant to the procedures for book-entry transfer
described below or (iii) comply with the guaranteed delivery procedures
described below.

     The Offer is not being made to holders of Preferred Shares. If holders of
Preferred Shares wish to participate in the Offer, they can convert their
Preferred Shares into Ordinary Shares and then tender the resulting Ordinary
Shares pursuant to the Offer. Alternatively, the Purchaser has been informed by
the Company that the Company intends to make available to holders of Preferred
Shares the opportunity to surrender their Preferred Shares for conversion into
Ordinary Shares conditional upon the Purchaser's acceptance for payment of
Ordinary Shares pursuant to the Offer. Holders of Preferred Shares will be
contacted separately regarding the procedures to be followed to conditionally
convert their Preferred Shares and tender the Ordinary Shares to be issued upon
such conversion. If a holder of Preferred Shares chooses to convert such
Preferred Shares into Ordinary Shares other than pursuant to the conditional
conversion referred to above, and tender the Ordinary Shares issued upon such
conversion, such holder must allow sufficient time to both follow the procedures
for converting the Preferred Shares and tendering the Ordinary Shares issued
upon such conversion prior to the Expiration Date of the Offer.

     Pursuant to the Rights Agreement, until the close of business on the
Distribution Date, the Rights will be transferred with and only with the
Certificates for Ordinary Shares and the surrender for transfer of any
Certificates will also constitute the transfer of the Rights associated with the
Ordinary Shares represented by such Certificates. Pursuant to an amendment to
the Rights Agreement dated as of July 9, 2001, no Distribution Date will occur
by reason of the commencement of the Offer, the acceptance for payment of, or
the payment for, Ordinary Shares pursuant to the Offer or the consummation of a
Compulsory Acquisition, a Scheme of Arrangement or the other transactions
contemplated by the Acquisition Agreement.

     If separate certificates representing the Rights are issued to Holders
prior to the time a Holder's Ordinary Shares are tendered pursuant to the Offer,
certificates representing a number of Rights equal to the number of Ordinary
Shares tendered must be delivered to the Depositary, or, if available, a
Book-Entry Confirmation received by the Depositary with respect thereto, in
order for such Ordinary Shares to be validly tendered. If the Distribution Date
occurs and separate certificates representing the Rights are not distributed
prior to the time Ordinary Shares are tendered pursuant to the Offer, Rights may
be tendered prior to a Holder receiving the certificates for Rights by use of
the guaranteed delivery procedures described below. A tender of Ordinary Shares
constitutes an agreement by the tendering Holder to deliver certificates
representing all Rights formerly associated with the number of Ordinary Shares
tendered pursuant to the Offer to the Depositary prior to expiration of the
period permitted by such guaranteed delivery procedures for delivery of
certificates for, or a Book-Entry Confirmation with respect to, Rights (the
"Rights Delivery Period"). However, after expiration of the Rights Delivery
Period, the Purchaser may elect to reject as invalid a tender of Ordinary Shares
with respect to which certificates for, or a Book-Entry Confirmation with
respect to, the number of Rights required to be tendered with such Ordinary
Shares have not been received by the Depositary. Nevertheless, the Purchaser
will be entitled to accept for payment Ordinary Shares tendered by a Holder
prior to receipt of the certificates for the Rights required to be tendered with
such Ordinary Shares, or a Book-Entry Confirmation with respect to such Rights,
and either (i) subject to complying with applicable rules and regulations of the
Commission, withhold payment for such Ordinary Shares pending receipt of the
certificates for, or a Book-Entry Confirmation with respect to, such Rights or
(ii) make payment for Ordinary Shares accepted for payment pending receipt of
the certificates for, or a Book-Entry Confirmation with respect to, such Rights
in

                                        13
   17

reliance upon the agreement of a tendering Holder to deliver Rights and such
guaranteed delivery procedures. Any determination by the Purchaser to make
payment for Ordinary Shares in reliance upon such agreement and such guaranteed
delivery procedures or, after expiration of the Rights Delivery Period, to
reject a tender as invalid will be made in the sole and absolute discretion of
the Purchaser.

     THE METHOD OF DELIVERY OF THE ORDINARY SHARES, CERTIFICATES, THE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE
BOOK-ENTRY TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING HOLDER,
AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE
DEPOSITARY (INCLUDING IN THE CASE OF 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.

     BOOK-ENTRY TRANSFER.  The Depositary will establish an account with respect
to the Ordinary Shares at the Book-Entry Transfer Facility for purposes of the
Offer within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of Ordinary Shares by (i) causing
such securities to be transferred in accordance with the Book-Entry Transfer
Facility's procedures into the Depositary's account and (ii) causing the Letter
of Transmittal to be delivered to the Depositary by means of an Agent's Message.
Although delivery of Ordinary Shares may be effected through book-entry
transfer, either the Letter of Transmittal (or manually signed copy thereof),
properly completed and duly executed, together with any required signature
guarantees, or any Agent's Message in lieu of the Letter of Transmittal, and any
other required documents, must, in any case, be transmitted to and received by
the Depositary prior to the Expiration Date at its address set forth on the back
cover of this Offer to Purchase, or the tendering Holder must comply with the
guaranteed delivery procedures described below. DELIVERY OF THE LETTER OF
TRANSMITTAL AND OTHER REQUIRED DOCUMENTS OR INSTRUCTIONS TO THE BOOK-ENTRY
TRANSFER FACILITY DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.

     SIGNATURE GUARANTEE.  All signatures on a Letter of Transmittal must be
guaranteed by a financial institution (including most banks, savings and loan
associations and brokerage houses) that is a participant in the Security
Transfer Agents Medallion Program, the New York Stock Exchange Medallion
Signature Guarantee Program or the Stock Exchange Medallion Program (each an
"Eligible Institution"), unless the Ordinary Shares tendered thereby are
tendered (i) by the registered holder(s) (which term, for purposes of this
document, shall include any participant in the Book-Entry Transfer Facility
whose name appears on a security position listing as the owner of Ordinary
Shares) of Ordinary Shares who has not completed the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on the
Letter of Transmittal or (ii) for the account of an Eligible Institution. See
Instruction 1 to the Letter of Transmittal.

     If a Certificate is registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made, or a
Certificate not accepted for payment or not tendered is to be returned to a
person other than the registered holder(s), then the Certificate must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear(s) on the Certificate,
with the signature(s) on such Certificate or stock powers guaranteed as
described above. See Instructions 1, 5 and 7 to the Letter of Transmittal.

     GUARANTEED DELIVERY.  If a Holder desires to tender Ordinary Shares
pursuant to the Offer and such Holder's Certificates are not immediately
available (including because certificates for Rights have not yet been
distributed by the Rights Agent) or time will not permit all required documents
to reach the Depositary prior to the Expiration Date or the procedure for
book-entry transfer cannot be completed on a timely basis, such Ordinary Shares
may nevertheless be tendered if all the following conditions are satisfied:

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

          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by the Purchaser, is received
     by the Depositary as provided below prior to the Expiration Date; and

                                        14
   18

          (iii) the Certificates for all tendered Ordinary Shares in proper form
     for transfer, together with a properly completed and duly executed Letter
     of Transmittal (or a copy thereof) with any required signature guarantee
     (or, in the case of a book-entry transfer, a Book-Entry Confirmation along
     with an Agent's Message) and any other documents required by such Letter of
     Transmittal, are received by the Depositary within three New York Stock
     Exchange, Inc. ("NYSE") trading days after the date of execution of the
     Notice of Guaranteed Delivery, or in the case rights certificates have been
     issued, three NYSE trading days after the date certificates for Rights are
     distributed to Holders by the Rights Agent. A trading day is a day on which
     the NYSE is open for business.

     Any Notice of Guaranteed Delivery may be delivered by hand to the
Depositary or transmitted by facsimile transmission, or by mail to the
Depositary and must include a guarantee by an Eligible Institution in the form
set forth in the Notice of Guaranteed Delivery. In the case of Ordinary Shares
held through the Book-Entry Transfer Facility, the Notice of Guaranteed Delivery
must be delivered to the Depositary by a participant by means of the
confirmation system of the Book-Entry Transfer Facility.

     OTHER REQUIREMENTS.  Notwithstanding any other provision hereof, payment
for Ordinary Shares accepted for payment pursuant to the Offer will, in all
cases, be made only after timely receipt by the Depositary of (i) Certificates
or a Book-Entry Confirmation of the delivery of such Ordinary Shares, and if
certificates evidencing Rights have been issued, such certificates or a
Book-Entry Confirmation, if available, with respect to such certificates (unless
the Purchaser elects, in its sole discretion, to make payment for the Ordinary
Shares pending receipt of such certificates or a Book-Entry Confirmation, if
available, with respect to such certificates), (ii) a properly completed and
duly executed Letter of Transmittal (or a copy thereof) with any required
signature guarantees (or, in the case of a book-entry transfer, an Agent's
Message) and (iii) any other documents required by the Letter of Transmittal.
Accordingly, tendering Holders may be paid at different times depending upon
when Certificates (or certificates for Rights) or Book-Entry Confirmations with
respect to Ordinary Shares (or Rights, if applicable) are actually received by
the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE ORDINARY
SHARE OFFER PRICE TO BE PAID BY THE PURCHASER, REGARDLESS OF ANY EXTENSION OF
THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.

     DETERMINATION OF VALIDITY.  All questions as to the validity, form,
eligibility (including, but not limited to, time of receipt) and acceptance for
payment of any tendered Ordinary Shares pursuant to any of the procedures
described above will be determined by the Purchaser, in its sole discretion,
whose determination will be final and binding on all parties. The Purchaser
reserves the absolute right to reject any or all tenders of any Ordinary Shares
determined by it not to be in proper form or if the acceptance for payment of,
or payment for, such Ordinary Shares may, in the opinion of the Purchaser's
counsel, be unlawful. The Purchaser also reserves the absolute right, in its
sole discretion (subject to the terms of the Acquisition Agreement) to waive any
of the conditions of the Offer or any defect or irregularity in any tender with
respect to Ordinary Shares of any particular Holder, whether or not similar
defects or irregularities are waived in the case of other Holders. No tender of
Ordinary Shares will be deemed to have been validly made until all defects and
irregularities have been cured or waived.

     Subject to the terms of the Acquisition Agreement, the Purchaser's
interpretation of the terms and conditions of the Offer (including the Letter of
Transmittal and the instructions thereto) will be final and binding.

     APPOINTMENT AS PROXY.  By executing a Letter of Transmittal (or delivering
an Agent's Message) as set forth above, a tendering Holder irrevocably appoints
each designee of the Purchaser as such Holder's attorney-in-fact and proxy, with
full power of substitution, to vote the Ordinary Shares as described below in
such manner as such attorney-in-fact and proxy (or any substitute thereof) shall
deem proper in its sole discretion, and to otherwise act (including pursuant to
written consent) to the full extent of such Holder's rights with respect to the
Ordinary Shares (and any and all dividends, distributions, rights or other
securities issued or issuable in respect of such Ordinary Shares on or after
July 17, 2001 (collectively, the "Distributions")) tendered by such Holder and
accepted for payment by the Purchaser prior to the time of such vote or action.
All such proxies and powers of attorney shall be considered coupled with an
interest in the tendered Ordinary Shares and shall be irrevocable and are
granted in consideration of, and are effective upon, the acceptance for

                                        15
   19

payment of such Ordinary Shares and all Distributions in accordance with the
terms of the Offer. Such acceptance for payment by the Purchaser shall revoke,
without further action, any other proxy or power of attorney granted by such
Holder at any time with respect to such Ordinary Shares and all Distributions,
and no subsequent proxies or powers of attorney will be given or written
consents executed (or, if given or executed, will not be deemed effective) with
respect thereto by such Holder. The designees of the Purchaser will, with
respect to the Ordinary Shares for which the appointment is effective, be
empowered to exercise all voting and other rights as they in their sole
discretion may deem proper at any annual, special, adjourned or postponed
meeting of the Company's shareholders, by written consent or otherwise, and the
Purchaser reserves the right to require that, in order for Ordinary Shares or
any Distributions to be deemed validly tendered, immediately upon the
Purchaser's acceptance for payment of such Ordinary Shares, the Purchaser must
be able to exercise all rights (including, without limitation, all voting rights
and rights of conversion) with respect to such Ordinary Shares and receive all
Distributions.

     BACKUP WITHHOLDING.  UNDER UNITED STATES FEDERAL INCOME TAX LAW, THE AMOUNT
OF ANY PAYMENTS MADE BY THE DEPOSITARY TO HOLDERS (OTHER THAN CORPORATE AND
CERTAIN OTHER EXEMPT HOLDERS) PURSUANT TO THE OFFER MAY BE SUBJECT TO BACKUP
WITHHOLDING TAX AT A RATE OF 31%. TO AVOID SUCH BACKUP WITHHOLDING TAX WITH
RESPECT TO PAYMENTS PURSUANT TO THE OFFER, A NON-EXEMPT, TENDERING "U.S. HOLDER"
(AS DEFINED BELOW) MUST PROVIDE THE DEPOSITARY WITH SUCH HOLDER'S CORRECT
TAXPAYER IDENTIFICATION NUMBER ("TIN") AND CERTIFY UNDER PENALTY OF PERJURY THAT
(I) THE TIN PROVIDED IS CORRECT (OR THAT SUCH HOLDER IS AWAITING A TIN) AND (II)
SUCH HOLDER IS NOT SUBJECT TO BACKUP WITHHOLDING TAX BY COMPLETING THE
SUBSTITUTE FORM W-9 INCLUDED AS PART OF THE LETTER OF TRANSMITTAL. IF BACKUP
WITHHOLDING APPLIES WITH RESPECT TO A HOLDER OR IF A HOLDER FAILS TO DELIVER A
COMPLETED SUBSTITUTE FORM W-9 TO THE DEPOSITARY OR OTHERWISE ESTABLISH AN
EXEMPTION, THE DEPOSITARY IS REQUIRED TO WITHHOLD 31% OF ANY PAYMENTS MADE TO
SUCH HOLDER. SEE SECTION 5 -- "CERTAIN UNITED STATES FEDERAL INCOME TAX
CONSEQUENCES" OF THIS OFFER TO PURCHASE AND THE INFORMATION SET FORTH UNDER THE
HEADING "IMPORTANT TAX INFORMATION" CONTAINED IN THE LETTER OF TRANSMITTAL.
UNDER RECENTLY ENACTED LEGISLATION, THE BACKUP WITHHOLDING TAX RATE OF 31% WILL
BE REDUCED AS OF AUGUST 7, 2001 TO 30.5%. THIS RATE WILL BE FURTHER REDUCED TO
30% FOR YEARS 2002 AND 2003, 29% FOR YEARS 2004 AND 2005, AND 28% FOR 2006 AND
THEREAFTER.

     The Purchaser's acceptance for payment of Ordinary Shares tendered pursuant
to the Offer will constitute a binding agreement between the tendering Holder
and the Purchaser on the terms and subject to the conditions of the Offer.

     4.  WITHDRAWAL RIGHTS.  Tenders of Ordinary Shares made pursuant to the
Offer are irrevocable other than as provided by applicable law and the
Acquisition Agreement except that such Ordinary Shares may be withdrawn at any
time prior to the Expiration Date and, unless theretofore accepted for payment
by the Purchaser pursuant to the Offer, may also be withdrawn at any time after
September 14, 2001, or at such later time as may apply if the Offer is extended
beyond that date (excluding any Subsequent Offering Period). In the event the
Purchaser provides a Subsequent Offering Period following the Offer, no
withdrawal rights will apply to Ordinary Shares tendered during such Subsequent
Offering Period or to Ordinary Shares previously tendered in the Offer and
accepted for payment.

     If the Purchaser extends the Offer (excluding any Subsequent Offering
Period), is delayed in its acceptance for payment of Ordinary Shares or is
unable to accept Ordinary Shares for payment pursuant to the Offer for any
reason, then, without prejudice to the Purchaser's rights under the Offer but
subject to the Purchaser's obligations under the Exchange Act, the Depositary
may, nevertheless, on behalf of the Purchaser, retain tendered Ordinary Shares,
and such Ordinary Shares may not be withdrawn except to the extent that
tendering Holders are entitled to withdrawal rights as described in this Section
4 -- "Withdrawal Rights." Any such delay will be an extension of the Offer to
the extent required by law.

     For a withdrawal to be effective, a written or facsimile transmission
notice of withdrawal must be timely received by the Depositary at its address
set forth on the back cover of this Offer to Purchase. Any such notice of
withdrawal must specify the name of the person who tendered the Ordinary Shares
to be withdrawn, the number of Ordinary Shares to be withdrawn and the name of
the registered holder of the Ordinary Shares, if different from that of the
person who tendered such Ordinary Shares. If Certificates to be withdrawn have

                                        16
   20

been delivered or otherwise identified to the Depositary, then, prior to the
physical release of such Certificates, the serial numbers shown on such
Certificates must be submitted to the Depositary and the signature(s) on the
notice of withdrawal must be guaranteed by an Eligible Institution, unless such
Ordinary Shares have been tendered for the account of an Eligible Institution.
Ordinary Shares tendered pursuant to the procedure for book-entry transfer as
set forth in Section 3 -- "Procedures for Tendering Ordinary Shares" may be
withdrawn only by means of the withdrawal procedures made available by the
Book-Entry Transfer Facility, must specify the name and number of the account at
the Book-Entry Transfer Facility to be credited with the withdrawn Ordinary
Shares and must otherwise comply with the Book-Entry Transfer Facility's
procedures.

     Withdrawals of tendered Ordinary Shares may not be rescinded without the
Purchaser's consent and any Ordinary Shares properly withdrawn will thereafter
be deemed not validly tendered for purposes of the Offer. All questions as to
the form and validity (including time of receipt) of notices of withdrawal will
be determined by the Purchaser, in its sole discretion, which determination will
be final and binding. None of Amerada Hess, the Purchaser, the Depositary, the
Information Agent, the Dealer Managers 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 any such notification.

     However, any Ordinary Shares properly withdrawn may be re-tendered at any
time prior to the Expiration Date by following any of the procedures described
in Section 3 -- "Procedures for Tendering Ordinary Shares."

     5.  CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES.  The receipt of
cash for Ordinary Shares pursuant to the Offer, the Compulsory Acquisition or
the Scheme of Arrangement by a U.S. Holder will be a taxable transaction for
United States federal income tax purposes and may also be a taxable transaction
under applicable state, local or foreign tax laws. For purposes of this
discussion, a "U.S. Holder" is a beneficial owner of Ordinary Shares who for
United States federal income tax purposes is (i) a citizen or resident of the
United States, (ii) a corporation or partnership 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 United States federal income
taxation regardless of its source or (iv) a trust if such trust has validly
elected to be treated as a United States person for United States federal income
tax purposes or a trust (a) the administration over which a United States court
can exercise primary supervision and (b) all of the substantial decisions of
which one or more United States persons have the authority to control.

     In general, a U.S. Holder will recognize gain or loss for United States
federal income tax purposes equal to the difference, if any, between the amount
realized from the sale of Ordinary Shares and such U.S. Holder's adjusted tax
basis in such Ordinary Shares. Assuming that the Ordinary Shares constitute a
capital asset in the hands of the U.S. Holder, such gain or loss will be capital
gain or loss. In the case of a noncorporate U.S. Holder, the maximum marginal
United States federal income tax rate applicable to such gain will be lower than
the maximum marginal United States federal income tax rate applicable to income
if such U.S. Holder's holding period for such Ordinary Shares exceeds one year.

     The foregoing discussion may not be applicable to certain types of Holders,
including Holders who acquired Ordinary Shares pursuant to the exercise of stock
options or otherwise as compensation, Holders that are not U.S. Holders and
Holders that are otherwise subject to special tax rules, such as financial
institutions, insurance companies, dealers or traders in securities or
currencies, tax-exempt entities, persons that hold Ordinary Shares as a position
in a "straddle" or as part of a "hedging" or "conversion" transaction for tax
purposes and persons that have a "functional currency" other than the United
States dollar.

     BACKUP WITHHOLDING TAX.  As noted in Section 3 -- "Procedures for Tendering
Ordinary Shares," a Holder (other than an "exempt recipient" (including a
corporation), a non-U.S. Holder that provides appropriate certification (if the
payor does not have actual knowledge that such certificate is false) and certain
other persons) that receives cash in exchange for Ordinary Shares may be subject
to United States federal backup withholding tax at a rate equal to 31%, unless
such Holder provides its TIN and certifies that such Holder is not subject to
backup withholding tax by submitting a completed Substitute Form W-9 to the
Depositary. Accordingly, each U.S. Holder should complete, sign and submit the
Substitute Form W-9 included as part of the Letter of Transmittal in order to
avoid the imposition of such backup withholding tax.
                                        17
   21

Under recently enacted legislation, the backup withholding tax rate of 31% will
be reduced as of August 7, 2001 to 30.5%. This rate will be further reduced to
30% for years 2002 and 2003, 29% for years 2004 and 2005, and 28% for 2006 and
thereafter.

     The United States federal income tax discussion set forth above is included
for general information and is based on income tax laws, regulations, rulings
and decisions now in effect, all of which are subject to change (possibly
retroactively). HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO
THE SPECIFIC TAX CONSEQUENCES OF THE OFFER TO THEM, INCLUDING THE APPLICATION
AND EFFECT OF THE ALTERNATIVE MINIMUM TAX AND STATE, LOCAL AND FOREIGN TAX LAWS.

the Offer, (ii) the date of completion of the Compulsory Acquisition, (iii) the
effective date of the Scheme of Arrangement and (iv) the termination of the

     CAPITAL STRUCTURE.  The authorized capital of the Company consists of (a)
200,000,000 Ordinary Shares and (b) 20,000,000 other shares, par value $0.01 per
share, of which 11,000,000 have been authorized as Preferred Shares and 200,000
have been authorized as Series A junior participating preferred shares (the
"Junior Preferred Stock").

     (a) SHARES

     As of July 5, 2001, the Company had 37,500,375 Ordinary Shares outstanding
and 5,180,265 Preferred Shares outstanding. As of July 5, 2001, no other shares
of any class of the share capital of the Company were outstanding.

     (b) RIGHTS

     On March 25, 1996, the Board of Directors of the Company authorized and
declared a dividend distribution of one Right for each Ordinary Share
outstanding at the close of business on March 25, 1996, and has authorized the
issuance of one Right for each Ordinary Share of the Company issued between
March 25, 1996 and the Distribution Date. Each Right entitles the holder to
purchase from the Company one one-thousandth of a share of the Junior Preferred
Stock at a price of $120 per one one-thousandth of a share of Junior Preferred
Stock, subject to adjustment.

     Currently, the Rights are evidenced by the Certificates for Ordinary Shares
registered in the names of the Holders (which Certificates shall be deemed also
to be certificates for Rights) and not by separate Right certificates, and the
Rights are transferable only in connection with the transfer of the underlying
Ordinary Shares (including a transfer to the Company).

     Generally, the Rights become exercisable after the earlier to occur of (i)
the tenth day following the first date of a public announcement by the Company
or an Acquiring Person (as defined below) that an Acquiring Person has become
such or such earlier date as a majority of the Company's Board of Directors
shall become aware of the existence of an Acquiring Person (such first date, the
"Share Acquisition Date") or (ii) the tenth business day after the commencement
by any person (other than the Company, any subsidiary of the Company, any
employee benefit plan of the Company or of any subsidiary of the Company, or any
entity or trustee holding Ordinary Shares for or pursuant to the terms of any
such plan or for the purpose of funding any such plan or funding other employee
benefits for employees of the Company or of any subsidiary of the Company,
hereinafter collectively referred to as the "Exempt Persons") of, or the first
public announcement of the intention of such person (other than an Exempt
Person) to commence, a tender or exchange offer, the consummation of which would
result in any person becoming the beneficial owner of 15% or more of the
Ordinary Shares then outstanding (each such person, an "Acquiring Person") (the
earlier of such dates being hereinafter referred to as the "Distribution Date").
The Purchaser has been advised by the Company that the Company and its Board of
Directors have taken all necessary action to render the Rights Agreement
inapplicable with respect to the Offer pursuant to the terms of the Acquisition
Agreement. The Rights Agreement and the rights conveyed thereby shall be
inapplicable to the transactions contemplated by the Acquisition Agreement and
the Principal Shareholders Agreement or any announcement thereof and any
acquisition by Amerada Hess, the Purchaser or any affiliates or associates of
each of beneficial ownership of
                                        19
   23

Ordinary Shares or Preferred Shares following the acquisition by Amerada Hess or
the Purchaser of any Ordinary Shares or Preferred Shares pursuant to the
Principal Shareholders Agreement or the Acquisition Agreement, until after such
time as the ownership of Ordinary Shares held by Amerada Hess, the Purchaser and
their respective affiliates and associates is reduced below certain levels.

     Notwithstanding the foregoing, (i) HM4 Triton, L.P. and its affiliates and
associates are deemed not to be an Acquiring Person for purposes of the Rights
Agreement as a result of any acquisition of Ordinary Shares by HM4 Triton, L.P.
or its affiliates and associates unless and until HM4 Triton, L.P.'s ownership
of Ordinary Shares is reduced below certain levels and (ii) Amerada Hess and the
Purchaser or the affiliates and associates of each are deemed not to be an
Acquiring Person for purposes of the Rights Agreement (x) unless and until the
Acquisition Agreement and Principal Shareholders Agreement shall terminate and
neither Amerada Hess nor the Purchaser purchases any Ordinary Shares or
Preferred Shares pursuant thereto or (y) if Amerada Hess or the Purchaser has
purchased any Ordinary Shares or Preferred Shares pursuant thereto, until after
such time as the ownership of Ordinary Shares held by Amerada Hess, the
Purchaser and their respective affiliates and associates is reduced below
certain levels. Notwithstanding anything in the Acquisition Agreement to the
contrary, neither a Share Acquisition Date nor a Distribution Date will be
deemed to have occurred as a result of the execution of the Acquisition
Agreement or the Principal Shareholders Agreement, or the public announcement or
consummation of the transactions contemplated thereby, or any other acquisition
by Amerada Hess, the Purchaser or any affiliates or associates of Ordinary
Shares or Preferred Shares, or any public announcement thereof after the
purchase by Amerada Hess, the Purchaser or any affiliates or associates of
Ordinary Shares or Preferred Shares pursuant to the Principal Shareholders
Agreement or the Acquisition Agreement, until after such time as the ownership
of Ordinary Shares held by Amerada Hess, the Purchaser and their respective
affiliates and associates is reduced below certain levels.

     If, among other events, any person becomes an Acquiring Person, each Right
not owned by the Acquiring Person, or an affiliate or associate of that
Acquiring Person, generally becomes the right to purchase a number of Ordinary
Shares equal to the number obtained by (x) multiplying the then current purchase
price (currently $120) by the number of one one-thousandths of a share of Junior
Preferred Stock for which a Right is then exercisable and (y) dividing that
product by 50% of the then current per share market price of the Ordinary Shares
on the date of the occurrence of such event. In addition, at any time after any
person becomes an Acquiring Person, if the Company is subsequently merged or
certain other extraordinary business transactions are consummated, each Right
generally becomes a right to purchase a number of Ordinary Shares of the person
with whom the Company has engaged in the foregoing transaction (the "Principal
Party") equal to the number obtained by (x) multiplying the then current
purchase price (currently $120) by the number of one one-thousandths of a share
of Junior Preferred Stock for which a Right was exercisable immediately prior to
the time any person first became an Acquiring Person and (y) dividing that
product by 50% of the then current per share market price of the ordinary shares
of such Principal Party on the date of the consummation of such merger or other
extraordinary business transaction.

     At any time prior to such time as any person becomes an Acquiring Person,
the Company may redeem the Rights, in whole but not in part, for $0.01 per
Right, payable in cash, Ordinary Shares or any other form of consideration
deemed appropriate by the Company's Board of Directors. At any time after any
person becomes an Acquiring Person and prior to the acquisition by such person
of beneficial ownership of a number of Ordinary Shares equal to 50% or more of
the number of outstanding Ordinary Shares, the Board of Directors of the Company
may exchange the Rights (other than Rights owned by such person which will have
become void), in whole or in part, at an exchange ratio of one Ordinary Share,
or one one-thousandth of a Preferred Share (or of a share of a class or series
of the Company's preference shares having equivalent rights, preferences and
privileges), per Right (subject to adjustment). The Rights will expire at the
close of business on May 22, 2005, if not redeemed or exchanged by the Company
at an earlier date. The Rights will terminate upon the effective time of the
Scheme of Arrangement or Compulsory Acquisition, as applicable.

     No holder, as such, of any Right certificate shall be entitled to vote,
receive dividends or be deemed for any purpose the holder of the number of
shares of Junior Preferred Stock or any other securities of the Company which
may at any time be issuable on the exercise of the Rights represented thereby,
nor shall
                                        20
   24

anything contained in the Rights Agreement or in any Right certificate be
construed to confer upon the holder of any Right certificate, as such, any of
the rights of a shareholder of the Company or any right to vote for the election
of directors or upon any matter submitted to shareholders at any meeting
thereof, or to give or withhold consent to any corporate action, or to receive
notice of meetings or other actions affecting shareholders (except as provided
in the Rights Agreement), or to receive dividends or subscription rights, or
otherwise, until the Rights evidenced by such Right certificate shall have been
exercised in accordance with the provisions of the Rights Agreement.

     (c) OPTIONS

     The Company has issued options or other rights to acquire Ordinary Shares
pursuant to a number of different stock option plans and other plans for the
benefit of non-management directors, executives and other employees. As of July
5, 2001, these options and other rights were exercisable into 6,013,818 Ordinary
Shares. See Section 11 -- "Purpose of the Offer; Plans for the Company; Certain
Agreements."

     BASIS OF PROJECTIONS.  Amerada Hess and the Purchaser have been advised
that the Projections were prepared to present certain production and financial
data on an operating basis, based on various assumptions. The Projections were
prepared without regard to financing requirements and are not presented on a
company-wide consolidated basis. The basis of accounting of the Projections is
consistent with the accounting policies normally adopted by the Company. The
Projections take account of the results reported by the Company's unaudited
interim consolidated financial statements for the three months ended March 31,
2001.

     ASSUMPTIONS.  Amerada Hess and the Purchaser have been advised by the
Company that the Projections are based on several assumptions, the principal
ones of which are the following:

          (a) a Nymex WTI crude oil price of $27.91 per barrel in 2001 and $25
     per barrel in each of the years 2002 through 2007;

          (b) a Colombian natural gas price of $1.18, $0.89, and $1.00 per Mcf
     in years 2001, 2002 and 2003, respectively, and of $1.80 per Mcf in each of
     the years 2004 through 2007;

          (c) a realized natural gas price of $3.15, $3.01, $2.90, $2.94 and
     $2.83 per MMbtu (million British thermal units) in years 2003, 2004, 2005,
     2006 and 2007, respectively, for the Company's Joint Development Area
     ("JDA") project in Malaysia-Thailand;

          (d) completion of production facilities of the Company's JDA project
     in accordance with the current schedule, commencement of production at the
     beginning of 2003 and increasing the production in 2005;

          (e) significant exploitation of existing discovered fields and
     exploitation of future exploration discoveries;

          (f) costs of floating production, storage and offloading vessels for
     development of the Company's fields in Equatorial Guinea remaining
     consistent with current estimates;
                                        24
   28

          (g) no asset impairment provisions;

          (h) no significant change in interest rates from those currently
     prevailing;

          (i) no material change in the rates or basis of taxation affecting the
     Company from those currently prevailing;

          (j) no material changes in general trading and economic conditions in
     the countries in which the Company operates or trades; and

          (k) no major disruptions to the business of the Company for reasons
     such as blow outs, pollution, fire and other hazards which may interrupt or
     terminate production.

                CAUTIONARY STATEMENTS CONCERNING THE PROJECTIONS

     The Projections were prepared by the Company's management for internal
purposes and not with a view to public disclosure or compliance with published
guidelines of the Commission, the guidelines established by the American
Institute of Certified Public Accountants for Prospective Financial Information
or generally accepted accounting principles. Neither Amerada Hess's nor the
Company's certified public accountants nor their financial advisors have
examined or compiled any of the Projections or expressed any conclusion or
provided any form of assurance with respect to the Projections and, accordingly,
assume no responsibility for the Projections. The Projections are included
herein to give the Holders access to information which was provided to Amerada
Hess and which is believed by Amerada Hess and the Purchaser to be not publicly
available and should not be deemed to establish or expand liability under
applicable law.

     Certain matters discussed herein (including, but not limited to, the
Projections) are forward-looking statements that are subject to certain risks
and uncertainties that could cause actual results to differ materially from the
statements included herein (including the Projections) and should be read with
caution. The Company has advised Amerada Hess and the Purchaser that the
Projections are subjective in many respects and thus susceptible to
interpretations and periodic revisions based on actual experience and recent
developments. While presented with numerical specificity, the Projections were
not prepared by the Company in the ordinary course of business and are based on
a variety of estimates and hypothetical assumptions made by management of the
Company with respect to, among other things, industry performance, political,
general economic, market, interest rate and financial conditions, reserve
estimates, production volumes, oil and natural gas prices, sales, cost of goods
sold, operating and other revenues and expenses, operating and capital
expenditures and working capital of the Company, and other matters which may not
be accurate, may not be realized and are inherently subject to significant
business, economic and competitive uncertainties and contingencies, all of which
are difficult to predict and many of which are beyond the Company's control.
Accordingly, there can be no assurance that the assumptions made in preparing
the Projections will prove accurate, and actual results may be materially
greater or less than those contained in the Projections. In addition, the
Projections do not take into account any of the transactions contemplated by the
Acquisition Agreement, including the Offer.

     For these reasons, as well as the bases and assumptions on which the
Projections were compiled, the inclusion of such Projections herein should not
be regarded as an indication that the Company, Amerada Hess, the Purchaser or
any of their respective affiliates or representatives considers such information
to be an accurate prediction of future events, and the Projections should not be
relied on as such. None of such persons assumes any responsibility for the
reasonableness, completeness, accuracy or reliability of such Projections. No
party nor any of their respective affiliates or representatives has made, or
makes, any representation to any person regarding the information contained in
the Projections and, except to the extent required by applicable law, none of
them intends to update or otherwise revise the Projections to reflect
circumstances existing after the date when made or to reflect the occurrence of
future events even in the event that any or all of the assumptions are shown to
be in error.

best of their knowledge, any of the persons listed in Schedule I hereto (i) has
been convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors) or (ii) was a party to any judicial or administrative proceeding
(except for matters that were dismissed without sanction or settlement) that
resulted in a judgment, decree or final order enjoining future violations of, or
prohibiting activities subject to, federal or state securities laws, or a
finding of any violation of such laws.

     Except as described in this Offer to Purchase (i) none of Amerada Hess, the
Purchaser or, to the best of their knowledge, any of the persons listed in
Schedule I to this Offer to Purchase, or any associate or majority-owned
subsidiary of Amerada Hess or the Purchaser or, to the best of their knowledge,
any associate or majority-owned subsidiary of any of the persons listed in
Schedule I to this Offer to Purchase, beneficially owns or has any right to
acquire, directly or indirectly, any equity securities of the Company and (ii)
none of Amerada Hess, the Purchaser, or to the best of their knowledge, any of
the persons listed in Schedule I to this Offer to Purchase has effected any
transaction in such equity securities during the past 60 days. The Purchaser and
Amerada Hess disclaim beneficial ownership of any Ordinary Shares owned by any
pension plans of Amerada Hess or the Purchaser or any pension plans of any
associate or majority-owned subsidiary of Amerada Hess or the Purchaser.

     Except as described in this Offer to Purchase, none of Amerada Hess, the
Purchaser or, to the best of their knowledge, any of the persons listed in
Schedule I to this Offer to Purchase has any contract, arrangement,
understanding or relationship with any other person with respect to any
securities of the Company, including, but not limited to, any contract,

any of the persons listed on Schedule I hereto has had any business relationship
or transaction with the Company or any of its executive officers, directors or
affiliates that is required to be reported under the rules and regulations of
the Commission applicable to the Offer. Except as set forth in this Offer to
Purchase, during the past two years, there have been no contacts, negotiations
or transactions between any of Amerada Hess, the Purchaser or any of their
subsidiaries or, to the best knowledge of Amerada Hess, or the Purchaser, any of
the persons listed in Schedule I to this Offer to Purchase, on the one hand, and
the Company or its affiliates, on the other hand, concerning an amalgamation,
scheme of arrangement, consolidation or acquisition, tender offer for or other
acquisition of securities, an election of directors or a sale or other transfer
of a material amount of assets.

     9.  SOURCE AND AMOUNT OF FUNDS.  The Offer is not conditioned on any
financing arrangements. The amount of funds required by the Purchaser to
purchase all of the outstanding Ordinary Shares pursuant to the Offer and to pay
related fees and expenses is expected to be approximately $2.8 billion. The
Purchaser currently intends to obtain all such funds through a combination of
loans from and/or capital contributions by Amerada Hess or other affiliates.
Amerada Hess currently intends to obtain such funds primarily through a new loan
facility and two existing loan facilities.

     Amerada Hess has received a commitment letter from Citibank, N.A.
("Citibank"), as administrative agent and lender, and Salomon Smith Barney,
Inc., as arranger, collectively the "Arrangers"), pursuant to which Citibank has
agreed to lend to Amerada Hess up to $1 billion under a two-year unsecured
revolving credit facility (the "Revolving Facility").

     Borrowings under the Revolving Facility will bear interest at a rate per
annum equal to (at Amerada Hess' election) (i) the administrative agent's base
rate or (ii) the London Interbank Offered Rate (LIBOR) plus a margin of 42.5 to
115.0 basis points on Eurodollar borrowings. There is also a facility fee on the
Revolving Facility at a rate of 7.5 to 35.0 basis points per annum, payable
quarterly in arrears, and a utilization fee of 5.0 to 25.0 basis points on the
facility to the extent more than one-third utilized. The margins and such fees
will be based on Amerada Hess' long-term senior unsecured non-credit-enhanced
debt ratings.

     This commitment is subject to, among other things, the negotiation and
execution of definitive financing agreements on terms satisfactory to Amerada
Hess and the Arrangers. The definitive documentation relating
                                        27
   31

to the Revolving Facility will contain representations and warranties,
covenants, events of default and conditions substantially identical to the
Credit Agreements described below. Amerada Hess has agreed to pay certain
expenses of, and provide customary indemnities for, the Arrangers. The foregoing
summary of the Revolving Facility is subject to preparation and completion of a
definitive credit agreement for the Revolving Facility. If and when definitive
agreements relating to the Revolving Facility are executed, copies will be filed
as exhibits to an amendment to the Tender Offer Statement on Schedule TO (the
"Schedule TO") relating to the Offer which the Purchaser has filed with the
Commission.

     Amerada Hess entered into two credit agreements, which were amended and
restated as of January 23, 2001 (the "Credit Agreements") to obtain funds
through two unsecured revolving loan facilities ("Credit Facility A" and "Credit
Facility B," collectively 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, Bank
of America, N.A., as co-documentation agent and arranger, Citibank, N.A., as
co-documentation agent and arranger, Barclays Bank PLC, as co-documentation
agent and arranger, and The Chase Manhattan Bank, N.A., as administrative agent.
The total committed funds made available under the Credit Facilities is $3.0
billion. Credit Facility A provides for $1.5 billion of short-term revolving
credit through January 2002 and bears interest and is subject to a facility fee
and utilization fee on the same basis as the Revolving Facility. Credit Facility
B provides for $1.5 billion five-year revolving credit, which expires in January
2006 and bears interest at a rate per annum equal to (at Amerada Hess' election)
(i) the administrative agent's base rate or (ii) LIBOR plus a margin of 40.0 to
112.5 basis points and is subject to a facility fee of 10.0 to 37.5 basis points
and (to the extent at least one-third utilized) a utilization fee of 5.0 to 25.0
basis points, with such margin and fees to be based on Amerada Hess' long-term
senior unsecured non-credit-enhanced debt ratings. Amerada Hess has the option
to extend up to $500 million of outstanding debt under Credit Facility A for an
additional 364-day period. The Credit Agreements may be used by Amerada Hess for
liquidity support of Amerada Hess' commercial paper program and general
corporate purposes, including working capital and the refinancing of certain
other facilities. The Credit Agreements contain certain restrictions on, among
other things, the creation of liens. The Credit Agreements also contain certain
events of default, including the liquidation or bankruptcy of Amerada Hess or
any of its significant subsidiaries. In addition, Amerada Hess has agreed to pay
certain fees and to reimburse each of the agents and arrangers for certain
expenses and to provide certain indemnities, as is customary for commitments of
the type described therein. The foregoing summary of the Credit Agreements is
qualified in its entirety by reference to the text of the Credit Agreements,
copies of which have been filed as exhibits to the Schedule TO. The Credit
Agreements may be inspected at, and copies may be obtained from, the same places
and in the manner set forth in Section 7-- "Certain Information Concerning the
Company."

     There are currently no alternative financing arrangements in place. Amerada
Hess is also considering alternative financing arrangements such as the issuance
of additional debt pursuant to either a public offering or private placement.

     The margin regulations promulgated by the Federal Reserve Board place
restrictions on the amount of credit that may be extended for the purposes of
purchasing margin stock (including the Ordinary Shares) if such credit is
secured directly or indirectly by margin stock. The Purchaser believes that the
financing of the acquisition of the Ordinary Shares will not be subject to the
margin regulations.

     Based on publicly available information, Amerada Hess estimates that there
is approximately $500 million in existing long-term debt of the Company. Amerada
Hess expects that this debt will continue to remain outstanding. The indenture
governing $300 million of debt is subject to a "change of control" provision
that provides that upon a "change of control" the notes evidencing such
indebtedness become redeemable at an amount equal to 101% of the principal
amount at the option of the holder. Amerada Hess does not expect that such
holders will elect to redeem this indebtedness because the redemption price is
less than the current market price of such indebtedness.

     10.  BACKGROUND OF THE OFFER.  In early 2001, as part of its ordinary
course strategic planning, Amerada Hess identified the Company as a possible
acquisition candidate. In a telephone call on March 12, 2001 that was initiated
by John B. Hess, Chairman of the Board and Chief Executive Officer of Amerada
Hess, Mr. Hess proposed to Thomas O. Hicks, Chairman of the Company and Chairman
and Chief Executive Officer of Hicks Muse, a possible sale of the Company to
Amerada Hess. Mr. Hess stressed that Amerada Hess would only be willing to
proceed if the Company agreed to deal with Amerada Hess exclusively for a
limited period of time. Mr. Hicks indicated his interest in exploring a
potential sale of the Company to Amerada Hess. Mr. Hess and Mr. Hicks agreed
that they would each instruct their management to engage in a more detailed
analysis of a possible sale transaction to determine whether or not to pursue
such a transaction.

     On May 9, 2001, the Company's financial advisors met with representatives
of Amerada Hess and discussed Amerada Hess' interest in pursuing an acquisition
of the Company and certain business and operational information about the
Company as part of Amerada Hess' preliminary due diligence. In mid-May, Amerada
Hess and the Company began negotiating a confidentiality agreement and Amerada
Hess indicated that it would require a due diligence review of certain
non-public business and legal information regarding the Company for the purpose
of determining if further exploration of a possible acquisition of the Company
was warranted. While the parties were negotiating the principal terms of the
confidentiality agreement, including provisions relating to exclusive dealing
with Amerada Hess, Amerada Hess furnished the Company with a request for
information for due diligence purposes. On June 4, 2001, Amerada Hess and the
Company signed the confidentiality agreement. In the confidentiality agreement,
Amerada Hess agreed not to pursue an unsolicited bid to acquire the Company
through June 4, 2002 and the Company agreed, as was required by Amerada Hess,
that the Company would deal exclusively with Amerada Hess regarding a potential
acquisition of the Company until July 15, 2001.

     On June 6, 2001, Mr. Hess and a senior executive of Amerada Hess met with
James C. Musselman, President and Chief Executive Officer of the Company at the
Amerada Hess office in New York to discuss further a possible acquisition of the
Company. Mr. Hess and Mr. Musselman primarily discussed the Company's business,
strategy and operations. They did not discuss possible acquisition prices or a
structure for the transaction. Representatives of the Company's financial
advisors were present at this meeting. This meeting was followed by further
discussions on June 6, 2001 about the Company's business and operations between
Mr. Musselman and W.S.H. Laidlaw, the President and Chief Operating Officer of
Amerada Hess.

     After the confidentiality agreement was signed, Amerada Hess received
information responsive to its earlier due diligence request. Amerada Hess made
several subsequent written requests for information and each time the Company
forwarded this information promptly.

     As part of Amerada Hess' due diligence, the Company's financial advisors
had suggested that senior management of Amerada Hess should meet with the
Company's senior management in Dallas and conduct further business and legal due
diligence of the Company to enable Amerada Hess to further develop a proposal to
acquire the Company. On June 25 and 26, 2001 Messrs. Hess and Laidlaw, together
with other senior executives of Amerada Hess, met with Mr. Musselman, A.E.
Turner, III, Senior Vice President and Chief Operating Officer and other senior
executives of the Company, together with representatives of the Company's
financial advisors, to conduct additional legal and business due diligence of
the Company and to discuss further a possible acquisition of the Company by
Amerada Hess.

     On July 2, 2001, Mr. Hess, on behalf of Amerada Hess, sent a letter to Mr.
Hicks proposing to acquire 100% of the share capital of the Company at a price
of $44.00 per Ordinary Share in cash and $176.00, plus accrued dividends, per
Preferred Share in cash. The proposal stated that Amerada Hess would rely solely
on its own cash resources, including available lines of credit, to finance the
acquisition. The proposal was conditioned on entering into a definitive
agreement with the Company's Principal Shareholders pursuant to which the
Principal Shareholders would grant to Amerada Hess an irrevocable option to
purchase their shares of the Company. The letter also stated that Amerada Hess
would require the Company to agree not to solicit, initiate, negotiate,
encourage or enter into an alternative acquisition proposal. The letter stated
that the proposal would only be available to the Company until July 10, 2001.

                                        29

     On July 3, 2001, Mr. Hicks telephoned Mr. Hess and stated that Mr. Hicks
had discussed Amerada Hess' proposal with certain members of the Company's Board
of Directors and that they had indicated their interest in pursuing the
proposal. Messrs. Hess and Hicks agreed that representatives of the Company and
Amerada Hess and their respective legal and financial advisors should meet as
soon as possible to conclude Amerada Hess' business and legal due diligence and
to negotiate the definitive terms of the acquisition.

     On July 4, 2001, Amerada Hess' legal advisors delivered to the Company and
its legal advisors and to Hicks Muse and its legal advisors a draft acquisition
agreement and a draft option agreement for the purchase of the Company shares
held by the Principal Shareholders.

     On the morning of July 5, 2001, the Company's Board of Directors met to
discuss, together with its legal and financial advisors, the structure of the
acquisition of the Company as reflected in the draft acquisition agreement
delivered to the Company on July 4th.

     On July 5, 2001, representatives of Amerada Hess and its financial advisors
met in Dallas with representatives of the Company and its financial advisors to
conduct additional confirmatory due diligence regarding the Company's business
and operations. Additionally, following the Company's Board of Directors
meeting, in the afternoon of July 5th, representatives of Amerada Hess and its
legal advisors met in Dallas with the Company's legal advisors to discuss the
structure of and significant issues related to the proposal to acquire the
Company as reflected in the draft acquisition agreement. In particular, the
Company's legal advisors negotiated for the ability of the Company to accept a
superior acquisition proposal if one were to be made prior to the completion of
the Offer. Amerada Hess' representatives and legal advisors insisted, however,
that Amerada Hess would not be willing to proceed if the Company could terminate
the acquisition agreement with Amerada Hess if a superior proposal was made to
acquire the Company. The representatives also discussed structural matters
related to the acquisition in connection with the requirements of Cayman Islands
law. In particular, they discussed the minimum amount of shares that Amerada
Hess would need to purchase in a tender offer to ensure that Amerada Hess could
effect an acquisition of any shares not tendered into the tender offer.
Additionally, the Company's legal advisors insisted that Amerada Hess would have
to narrow the scope of the conditions to its tender offer.

     Following these discussions, Amerada Hess' representatives and legal
advisors met with the legal advisor for Hicks Muse during the afternoon of July
5th to negotiate the terms of Amerada Hess' proposed option to purchase the
Ordinary Shares and Preferred Shares owned by the Principal Shareholders. Hicks
Muse's legal advisor insisted that the Principal Shareholders would not grant to
Amerada Hess an option to purchase such shares unless the Principal Shareholders
had the ability to terminate the option if the Company terminated its
acquisition agreement with Amerada Hess to pursue a superior acquisition
proposal. Hicks Muse's legal advisor indicated that the Principal Shareholders
would, however, be willing to commit to sell their Ordinary Shares and Preferred
Shares to Amerada Hess if Amerada Hess was committed to purchase such shares
regardless of whether or not Amerada Hess purchased any Ordinary Shares in the
Offer.

     On July 6, 2001, Mr. Hess telephoned Mr. Hicks to discuss the progress of
the negotiations. Mr. Hess and Mr. Hicks discussed the outstanding issues. Mr.
Hess agreed to increase Amerada Hess' proposal to $45.00 per Ordinary Share in
cash and to limit Amerada Hess' conditions to its offer if the Company's Board
of Directors would agree to withdraw its request for the ability to terminate
the agreement in the event a superior proposal were received. He also agreed
that Amerada Hess would irrevocably commit to the purchase of the Ordinary
Shares and Preferred Shares owned by the Principal Shareholders whether or not
Amerada Hess completed the Offer, if the Principal Shareholders would
irrevocably commit to sell such shares to Amerada Hess. The Company's Board of
Directors then met and discussed, together with the Company's legal and
financial advisors, the status of the negotiations.

     Thereafter, from Friday, July 6th through Monday, July 9th, representatives
of Amerada Hess and the Company and their respective legal advisors negotiated
the terms of the acquisition and finalized the definitive Acquisition Agreement
and related documents. Additionally, Amerada Hess' representatives and legal
advisors negotiated with the Company's and Hicks Muse's legal advisors and
finalized the definitive Principal Shareholders Agreement.

     The Company's Board of Directors met on July 9, 2001 to consider, with the
advice and assistance of its legal and financial advisors, the proposed
acquisition of the Company by Amerada Hess and the Acquisition Agreement and
related documentation to effect the acquisition. The Company's Board of
Directors unanimously approved the Offer and the Acquisition Agreement and the
related documents. Amerada Hess' Board of Directors met later that day and
unanimously approved the acquisition of the Company. The Acquisition Agreement
and the Principal Shareholders Agreement and related documents were then
executed and delivered by the Company, Amerada Hess and the Principal
Shareholders. On the morning of July 10, 2001, Amerada Hess and the Company
issued a joint press release announcing the transaction.

     11.  PURPOSE OF THE OFFER; PLANS FOR THE COMPANY; CERTAIN AGREEMENTS.

     PURPOSE OF THE OFFER.  The purpose of the Offer is to enable Amerada Hess
to acquire as many outstanding Ordinary Shares as possible as a first step in
acquiring the entire equity interest in the Company. The purpose of the
Compulsory Acquisition or the Scheme of Arrangement following the purchase of
Ordinary Shares in the Offer is for Amerada Hess to acquire all remaining
Ordinary Shares not purchased pursuant to the Offer. Upon consummation of the
Compulsory Acquisition or the Scheme of Arrangement, the Company will become a
wholly owned subsidiary of Amerada Hess. The Offer is being made pursuant to the
Acquisition Agreement.

     COMPULSORY ACQUISITION.  If, following the consummation of the Offer, the
Purchaser has accepted for payment at least 90% in value of the Ordinary Shares
then, subject to and in accordance with the Companies Law, the Purchaser
currently intends, promptly following the expiration of four months from the
commencement of the Offer and in no event later than two months following the
expiration of such four month period, to give notice in the prescribed manner to
each shareholder that has not tendered his or her Ordinary Shares to the
Purchaser pursuant to the Offer (a "Dissenting Shareholder") that it desires to
acquire such Dissenting Shareholder's Ordinary Shares pursuant to the procedure
set out in Section 88 of the Companies Law relating to a Compulsory Acquisition.
A Compulsory Acquisition will not require any shareholder approval. The
Purchaser is making the Offer because the Purchaser believes that it is the
means by which it will most likely be able to effect the acquisition, while at
the same time affording all other shareholders an equal opportunity to sell
their Ordinary Shares at the applicable cash price per Ordinary Share offered in
the Offer. Schedule II sets forth, in its entirety, Section 88 of the Companies
Law and the prescribed manner of notice to Dissenting Shareholders.

     SCHEME OF ARRANGEMENT.  If Amerada Hess and the Purchaser are not able to
effect a Compulsory Acquisition or the Offer expires without the purchase of any
Ordinary Shares thereunder and has remained open for the times referred to in
the Acquisition Agreement, Amerada Hess or the Purchaser may request that the
Company proceed with a Scheme of Arrangement under Sections 86 and 87 of the
Companies Law. If Amerada Hess or the Purchaser do not purchase any Ordinary
Shares in the Offer and fail to request that the Company pursue a Scheme of
Arrangement within ten business days after the expiration date of the Offer, the
Company will have the right to terminate the Acquisition Agreement and, if the
Acquisition Agreement is terminated, the Company will no longer have any
obligation to take any actions to effect a Scheme of Arrangement. In the event
that the Scheme of Arrangement becomes effective pursuant to Sections 86 and 87
of the Companies Law, each Ordinary Share would be acquired by the Purchaser at
the same Ordinary Share Offer Price in cash as paid in the Offer and if there
are Preferred Shares outstanding on the commencement of the Scheme of
Arrangement each Preferred Share would be converted into the right to receive an
amount in cash, without interest thereon, equal to $180, plus any accumulated
and unpaid dividends thereon. Under Section 86 of the Companies Law and upon an
application to the Court by the Company, the Court may order a meeting of the
shareholders of the Company or a class of shareholders of the Company, as the
case may be, to be summoned to consider and vote upon the Scheme of Arrangement.
At such meeting(s), the affirmative vote of a majority in number representing
75% in value of each class of the shares present in person or by proxy at the
meeting thereon is required to approve and adopt the Scheme of Arrangement. For
the purposes of approval of the Scheme of Arrangement, it should be noted that
any Ordinary Shares owned by Amerada Hess, the Purchaser or any affiliate
thereof would not, on the basis of existing case law (which would be persuasive
but not binding on the Court), be included in the class of holders of Ordinary
Shares who have not, at the time of the meeting, sold their Ordinary Shares
pursuant to the Offer. Schedule II sets forth, in their
                                        31
   35

entirety, Sections 86 and 87 of the Companies Law. BECAUSE A SCHEME OF
ARRANGEMENT INVOLVES A COURT PROCEEDING AND SHAREHOLDER APPROVAL, THE PURCHASE
OF ORDINARY SHARES AND THEREFORE THE RECEIPT OF FUNDS THROUGH A SCHEME OF
ARRANGEMENT CANNOT BE ASSURED AND THE RECEIPT OF FUNDS COULD BE SUBSTANTIALLY
DELAYED.

     OTHER.  If the Purchaser (a) is not able to acquire all remaining Ordinary
Shares pursuant to a Compulsory Acquisition or Scheme of Arrangement following
the purchase of Ordinary Shares pursuant to the Offer, or (b) is not able to
effect the Scheme of Arrangement if the Offer expires without the purchase of
any Ordinary Shares thereunder, the Purchaser will explore other alternatives to
acquire the entire equity interest in the Company. More particularly, the
Purchaser may seek to acquire either additional Ordinary Shares or the entire
remaining equity interest in the Company, and the Purchaser may seek to pursue
other transactions with the Company and/or its subsidiaries, which may include
extraordinary corporate transactions such as a reorganization, liquidation,
reincorporation to a jurisdiction that permits mergers or amalgamations, reverse
stock split, or sale or transfer of some or all of the Company's assets.
Although the Purchaser currently has no plans or proposals with respect to such
other means, future Ordinary Share acquisitions may be by means of open market
or privately negotiated purchases, or otherwise. Such transactions might involve
the exchange of cash or securities of the Purchaser and/or Amerada Hess, or some
combination of cash and securities, and may be on terms and at prices more or
less favorable than those of the Offer. Additionally, to the extent that any
Preferred Shares are outstanding following the expiration of the Offer, the
Purchaser may seek to cause the Company to redeem the Preferred Shares in
accordance with their terms.

     The decision to enter into such future transactions and the forms they
might take will depend upon whether such transactions are in the best interests
of Amerada Hess and the Purchaser and relevant legal considerations and
circumstances then existing, including the financial resources of the Purchaser
and Amerada Hess and the business, tax and accounting objectives of the
Purchaser and Amerada Hess, the performance of the Ordinary Shares in the
market, if any, the availability and alternative uses of funds, money market and
stock market conditions and general economic conditions. The Purchaser and/or
Amerada Hess also may engage in certain of such transactions during the period
following the expiration or termination of the offer and prior to any Compulsory
Acquisition or Scheme of Arrangement.

     APPRAISAL RIGHTS.  None of the Companies Law, the Company's Articles of
Association, the Company's Memorandum of Association, nor the Offer provides for
appraisal rights or other similar rights. Appraisal rights will not be
voluntarily provided by the Company or the Purchaser.

     However, under Section 88(1) of the Companies Law, if the Purchaser
acquires (or receives unconditional acceptances of the Offer in respect of) at
least 90% in value of the Ordinary Shares within four months after the
commencement of the Offer, then it may give notice (the "Notice") at any time
within two months following the expiration of the four-month period to any
Dissenting Shareholder that it desires to acquire the Ordinary Shares held by
such Dissenting Shareholder, on the same terms as the Offer. Each Dissenting
Shareholder will then have one month from the date the Notice has been given to
make an application to the Court for an order (an "Order") preventing the
Purchaser from so acquiring his or her Ordinary Shares. If such application is
not timely made or if an Order is not obtained by such Dissenting Shareholder,
then the Purchaser shall, on the expiration of one month from the date the
Notice has been given or after any appeal to the Court has been disposed with,
upon transmission of a copy of the Notice to the Company and payment of the
applicable per Ordinary Share price to the Company, the Company will be required
to register the Purchaser as the holder of those Ordinary Shares. Any sums paid
to the Company in respect of Ordinary Shares to be acquired from Dissenting
Shareholders pursuant to a Compulsory Acquisition under Section 88 of the
Companies Law are required to be held by the Company in trust for such
Dissenting Shareholders.

     The Purchaser has been advised by its Cayman Islands counsel that, although
there are no Cayman Islands cases that have considered when a dissenting
shareholder can prevent an acquirer from purchasing such dissenting
shareholder's shares, English case law, which would be persuasive although not
binding before the Court, has established that such an application by a
shareholder would require allegations of unfairness to be established and that
the burden is on the applicant to establish such allegation. In addition, the
English

                                        32
   36

courts have traditionally attached considerable weight to the fact that a large
body of shareholders has accepted the relevant offer. The Purchaser has also
been advised by its Cayman Islands counsel that there is case law to suggest
that a recommendation by the Board of Directors upon independent advice, such as
a fairness opinion, is regarded as significant in the determination of any
unfairness.

     THE FOREGOING SUMMARY OF THE RIGHTS OF OBJECTING HOLDERS DOES NOT PURPORT
TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE FOLLOWED BY HOLDERS DESIRING
TO EXERCISE ANY AVAILABLE DISSENSION RIGHTS.

     The provisions of the Companies Law are complex and technical in nature.
Holders desiring to exercise their dissension rights may wish to consult
counsel, since the failure to comply strictly with these provisions will result
in the loss of their dissension rights.

     COMPOSITION OF THE BOARD OF DIRECTORS.  The Acquisition Agreement provides
that promptly upon the acceptance for payment of, and payment for, Ordinary
Shares pursuant to the Offer, the Purchaser will be entitled to designate
representatives to serve on the Board of Directors of the Company in proportion
to the voting power of the Ordinary Shares owned by the Purchaser following such
purchase (determined on an as-converted basis assuming that all then outstanding
Preferred Shares are converted into Ordinary Shares); provided, that under
certain circumstances at least two members of the Board of Directors shall be
persons who were directors as of the time of signing of the Acquisition
Agreement. The Purchaser expects that such representation would permit the
Purchaser to exert substantial influence over the Company's conduct of its
business and operations.

     PLANS FOR THE COMPANY.  Subject to certain matters described below, it is
currently expected that, initially following the completion of the Offer, the
Compulsory Acquisition or the Scheme of Arrangement, the business and operations
of the Company will generally continue as they are currently being conducted.
Amerada Hess currently intends to cause the Company's operations to continue to
be run and managed by, among others, certain of the Company's existing executive
officers. Amerada Hess will continue to evaluate all aspects of the business,
operations, capitalization and management of the Company during the pendency of
the Offer and after the consummation of the Offer, the Compulsory Acquisition or
the Scheme of Arrangement and will take such further actions as it deems
appropriate under the circumstances then existing. Amerada Hess intends to seek
additional information about the Company during this period. Thereafter, Amerada
Hess intends to review such information as part of a comprehensive review of the
Company's business, operations, capitalization and management.

     As a result of the completion of the Offer, the interest of Amerada Hess in
the Company's net book value and net earnings will be in proportion to the
number of Ordinary Shares owned directly or indirectly by Amerada Hess. If the
Compulsory Acquisition is consummated or the Scheme of Arrangement becomes
effective, Amerada Hess' interest in such items and in the Company's equity
generally will equal 100% and Amerada Hess and its subsidiaries will be entitled
to all benefits resulting from such interest, including all income generated by
the Company's operations and any future increase in the Company's value.
Similarly, after completion of the Offer, the Compulsory Acquisition or the
Scheme of Arrangement becomes effective, Amerada Hess will also bear its
proportionate share of the risk of losses generated by the Company's operations
and any future decrease in the value of the Company. Subsequent to the
consummation of the Compulsory Acquisition or upon the Scheme of Arrangement
becoming effective, current shareholders of the Company will cease to have any
equity interest in the Company, will not have the opportunity to participate in
the earnings and growth of the Company and will not have any right to vote on
corporate matters. Similarly, shareholders will not face the risk of losses
generated by the Company's operations or decline in the value of the Company
after the consummation of the Compulsory Acquisition or upon the Scheme of
Arrangement becoming effective. If the Offer is completed but a Compulsory
Acquisition or Scheme of Arrangement is not completed, the current shareholders
of the Company whose Ordinary Shares are not purchased in the Offer will have a
proportionate share of the equity interests in the Company and a proportionate
opportunity to participate in the earnings and growth of the Company and to
share in its losses or declines in value.

     The Ordinary Shares are currently traded on the NYSE. Following the
consummation of the Compulsory Acquisition or upon the Scheme of Arrangement
becoming effective, the Ordinary Shares will no longer be listed on the NYSE and
the registration of the Ordinary Shares under the Exchange Act will be
terminated.
                                        33
   37

Accordingly, there will be no publicly traded equity securities of the Company
outstanding and the Company will no longer be required to file periodic reports
with the Commission. If the Offer is completed but there is either no Compulsory
Acquisition or the Scheme of Arrangement is not effective, there may still be so
few Holders that the Ordinary Shares will no longer meet the requirements for
listing on the NYSE or registration under the Exchange Act. See Section
13 -- "Effect of the Offer on the Market for the Shares; Exchange Act
Registration."

     The Purchaser may seek to cause the Company to redeem the Preferred Shares
in accordance with their terms.

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

     ACQUISITION AGREEMENT.  THE FOLLOWING IS A SUMMARY OF THE MATERIAL TERMS OF
THE ACQUISITION AGREEMENT. THE SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
TO THE ACQUISITION AGREEMENT, A COPY OF WHICH HAS BEEN FILED WITH THE COMMISSION
AS AN EXHIBIT TO THE SCHEDULE TO. THE ACQUISITION AGREEMENT MAY BE INSPECTED AT,
AND COPIES MAY BE OBTAINED FROM, THE SAME PLACES AND IN THE MANNER SET FORTH IN
SECTION 7 -- "CERTAIN INFORMATION CONCERNING THE COMPANY."

     THE OFFER.  The Acquisition Agreement provides that so long as the
Acquisition Agreement has not been terminated and so long as none of the events
described in Section 14 -- "Conditions of the Offer" (the "Tender Offer
Conditions") has occurred and is continuing, as promptly as practicable after
the date of the Acquisition Agreement (but in any event not later than seven
business days after the first public announcement of its execution and
delivery), the Purchaser will commence the Offer. The obligation of the
Purchaser to accept for payment and to pay for any Ordinary Shares tendered in
the Offer and not withdrawn is subject only to the Tender Offer Conditions, any
of which, subject to the proviso below, may be waived by Amerada Hess or the
Purchaser in whole or in part in their sole discretion. The Tender Offer
Conditions are for the sole benefit of Amerada Hess and the Purchaser and may be
asserted by Amerada Hess and the Purchaser regardless of the circumstances
giving rise to any such Tender Offer Conditions. Amerada Hess and the Purchaser
have expressly reserved the right to modify the terms of the Offer; provided,
however, that neither Amerada Hess nor the Purchaser may (and Amerada Hess has
agreed to cause the Purchaser not to), without the prior written consent of the
Company, (i) reduce the number of Ordinary Shares to be purchased pursuant to
the Offer, (ii) reduce the Ordinary Share Offer Price, (iii) impose any
additional conditions to the Offer, (iv) change the form of consideration
payable in the Offer, (v) make any change to the terms of the Offer, including
without limitation the Tender Offer Conditions, that is materially adverse in
any manner to the Holders, (vi) amend or waive the Minimum Condition, except
that Amerada Hess or the Purchaser may, at any time, amend the Minimum Condition
to equal the number of Ordinary Shares representing a majority of the total
number of votes of the outstanding Ordinary Shares on a fully diluted basis, or
(vii) extend the Expiration Date; provided, however, that Amerada Hess or the
Purchaser may extend the Expiration Date (x) as required by any rule, regulation
or interpretation of the Commission or (y) in the event that any condition to
the Offer is not satisfied or waived as of the scheduled Expiration Date, for
such successive periods of up to ten business days at a time (or such longer
period as may be approved by the Company) until the earlier of the acceptance
for payment of any Ordinary Shares pursuant to the Offer or the date that is 60
days from the commencement of the Offer. Notwithstanding anything in the
foregoing to the contrary, the Company may require the Purchaser to extend the
Offer on one occasion for a maximum period of ten days if at the scheduled
Expiration Date, the Tender Offer Conditions (assuming for this purpose that the
Minimum Condition has not been amended in accordance with clause (vi) above)
have not been satisfied. In addition, notwithstanding anything in the
Acquisition Agreement to the contrary, if not already disclosed in the Offer to
                                        34
   38

Purchase, Amerada Hess and the Purchaser may amend the Schedule TO to permit the
announcement of a Subsequent Offering Period, and the Purchaser may include a
Subsequent Offering Period for up to a maximum of 20 business days.
Notwithstanding the foregoing, if the Purchaser amends the Minimum Condition as
permitted by clause (vi) above and accepts Ordinary Shares tendered and not
withdrawn for payment pursuant to the terms of the Offer, then (i) the Purchaser
may make available a Subsequent Offering Period by extending the Offer on one
occasion for up to a maximum of twenty (20) business days and (ii) the Company
may require the Purchaser to make a Subsequent Offering Period available to the
Holders by extending the Offer on one occasion, for up to a maximum of twenty
(20) business days. If at any Expiration Date, the number of Ordinary Shares
validly tendered into and not withdrawn from the Offer, including all Ordinary
Shares validly tendered and not withdrawn from the Offer by the Principal
Shareholders (including, for this purpose, the conditional surrender for
conversion of, and tender of Ordinary Shares issuable upon conversion of,
Preferred Shares in accordance with the Principal Shareholders Agreement) will
result in the Minimum Condition being satisfied and all other Tender Offer
Conditions have been satisfied or waived, the Purchaser will be obligated to
accept for payment and pay for all such Ordinary Shares so tendered. If the
Purchaser accepts for payment any Ordinary Shares in the Offer, Amerada Hess or
the Purchaser must pay for all of the Ordinary Shares tendered and not withdrawn
in the Offer as soon as practicable after the scheduled Expiration Date, as it
may be extended pursuant to the Acquisition Agreement, but in any event no later
than the third business day after the date Amerada Hess or the Purchaser accepts
them and must pay for all Ordinary Shares tendered in the Subsequent Offering
Period, if applicable, promptly after such Ordinary Shares are tendered.

     The Company has consented to the Offer and the Scheme of Arrangement and
has represented that (a) the Board of Directors of the Company has (i)
determined by unanimous vote that each of the Offer, the Scheme of Arrangement
and the Compulsory Acquisition is fair to, and in the best interests of the
Company and the holders of Shares (the Preferred Shares and the Ordinary Shares
together, the "Shares") (other than, in the case of the transactions
contemplated by the Principal Shareholders Agreement, the Principal
Shareholders), (ii) approved the Offer, the Scheme of Arrangement and the
Compulsory Acquisition, (iii) resolved, subject to the terms of the Acquisition
Agreement, to recommend that the Holders accept the Offer and tender their
Ordinary Shares pursuant to the Offer and that the holders of Shares approve the
Scheme of Arrangement, if such approval is sought and (iv) taken all other
action necessary to render any applicable takeover statutes and the Rights
Agreement and the Rights inapplicable to the Offer, the Scheme of Arrangement
and the Compulsory Acquisition; (b) J.P. Morgan Securities Inc. has delivered to
the Board of Directors of the Company its opinion that the consideration to be
received pursuant to the Offer and either the Scheme of Arrangement or the
Compulsory Acquisition, as applicable, by the holders of Shares (other than
Amerada Hess or any direct or indirect subsidiary thereof), is fair, from a
financial point of view, to such holders (other than, in the case of the
transactions contemplated by the Principal Shareholders Agreement, the Principal
Shareholders), subject to the assumptions and qualifications contained in that
opinion; and (c) it has been advised that each of its directors and executive
officers intends to tender pursuant to the Offer all Ordinary Shares owned of
record and beneficially by him or her except to the extent such tender would
violate applicable securities laws.

     COMPULSORY ACQUISITION.  In the event that, following the purchase of
Ordinary Shares pursuant to the Offer (including any Subsequent Offering
Period), Amerada Hess, the Purchaser and any other subsidiary of Amerada Hess
shall own Ordinary Shares which represent at least ninety percent (90%) in value
of the Ordinary Shares affected, the Company, Amerada Hess and the Purchaser
agree to take all necessary and appropriate action for the Purchaser to effect
the Compulsory Acquisition.

     SCHEME OF ARRANGEMENT.  Subject to the obligation of Amerada Hess and the
Purchaser to effect the Compulsory Acquisition, promptly following the
Acceptance Date (as defined below) and, if applicable, the Subsequent Offering
Period, or the expiration of the Offer without the purchaser of any Ordinary
Shares thereunder, (A) if the Offer has remained open for a minimum of twenty
business days, plus any extension of the Expiration Date (up to an additional
(10) days) that has been required by the Company in accordance with the
Acquisition Agreement, and (B) if requested by Amerada Hess or the Purchaser, in
its sole discretion and in accordance with applicable law, the Company shall
cause an application to be made to the

                                        35
   39

Court requesting the Court to summon the Shareholders' Meetings, if directed by
the Court, convene such Shareholders' Meetings seeking the approval required
under Section 86(2) of the Companies Law and subject to such approval being
obtained, cause a petition to be presented to the Court seeking the sanctioning
of the Scheme of Arrangement and file such other documents as are required to be
duly filed with the Court to effect the Scheme of Arrangement. The Company
shall, if necessary, hold an extraordinary general meeting of its shareholders,
subject to the Scheme of Arrangement taking full force and effect, to approve
and adopt new Articles of Association of the Company that shall be substantially
identical to the Purchaser's articles of association, except as otherwise
required by the Acquisition Agreement. In furtherance of the foregoing, the
Company shall take all action necessary to solicit from its shareholders
proxies, and shall take all other action necessary and advisable to secure the
vote of shareholders required by the Companies Law and by the Memorandum of
Association of the Company or the Articles of Association of the Company to
obtain approval of the Scheme of Arrangement. Except as summarized below under
the heading -- "No Solicitation," the Board of Directors of the Company shall
recommend that the holders of Ordinary Shares and Preferred Shares vote in favor
of the approval of the Scheme of Arrangement at the Shareholders' Meetings, and,
except as summarized below under the heading -- "No Solicitation," the Company
agrees that it shall include in the Proxy Statement the recommendation of its
Board of Directors that the shareholders of the Company adopt the Acquisition
Agreement and approve the Scheme of Arrangement. Amerada Hess shall cause all
Shares owned by Amerada Hess and its direct and indirect subsidiaries (including
the Purchaser) to be voted in favor of approval of such Scheme of Arrangement.

     As promptly as practicable following Amerada Hess' request, the Company
shall promptly prepare and file with the Commission a preliminary proxy
statement or information statement (together with any amendment or supplement
thereto, the "Proxy Statement") and shall promptly use its commercially
reasonable efforts to respond to the comments of the Commission, if any, in
connection therewith and to furnish all information regarding the Company that
is required in the definitive Proxy Statement (including, without limitation,
financial statements and supporting schedules and certificates and reports of
independent public accountants). Amerada Hess, the Purchaser and the Company
shall cooperate with each other in the preparation of the Proxy Statement.
Without limiting the generality of the foregoing, each of Amerada Hess and the
Purchaser shall furnish to the Company for inclusion in the Proxy Statement the
information relating to it required by the Exchange Act to be set forth in the
Proxy Statement. The Company shall cause the definitive Proxy Statement to be
mailed to the shareholders of the Company and, if necessary, after the
definitive Proxy Statement shall have been so mailed, promptly circulate
amended, supplemental or supplemented proxy material and, if required in
connection therewith, resolicit proxies. The Company shall not use any proxy
material in connection with the meeting of its shareholders without Amerada
Hess' prior approval, except as required by law or the Commission.

     If deemed necessary or advisable by Amerada Hess, for purposes of the
hearing by the Court of the petition to sanction the Scheme of Arrangement, the
parties shall hold a pre-closing on the business day prior to the day of such
hearing (or such earlier time as reasonably requested by Amerada Hess if
necessary to prepare and file any affidavit in connection with such hearing) for
the purpose of determining which of the conditions to the Scheme of Arrangement
described below are satisfied as of such date.

     As soon as practicable after receipt of an order from the Court sanctioning
the Scheme of Arrangement, the parties shall convene at a location designated by
Amerada Hess for the purpose of confirming the satisfaction of the following
conditions: (i) no temporary restraining order, preliminary or permanent
injunction or other order shall have been issued by any federal, state or
foreign court or by any federal, state or foreign governmental entity, and no
other legal restraint or prohibition preventing the consummation of the Scheme
of Arrangement shall be in effect; (ii) no federal, state or non-United States
statute, rule, regulation, executive order, decree or order of any kind shall
have been enacted, entered, promulgated or enforced by any court or governmental
entity which prohibits, restrains, restricts or enjoins the consummation of the
Scheme of Arrangement or has the effect of making the Scheme of Arrangement
illegal; and (iii) the waiting period (and any extension thereof) applicable to
the consummation of the transactions contemplated by the Acquisition Agreement
under the HSR Act, if any, shall have expired or been terminated (the "Scheme
Closing Date"). The closing of the Scheme of Arrangement (the "Scheme Closing")
shall be deemed to

                                        36
   40

occur when all conditions set forth above are satisfied (other than any such
condition which has been waived) and all of the actions that are necessary to
consummate a Scheme of Arrangement have occurred.

     As soon as practicable following the Scheme Closing, the Company shall
cause a copy of the Court order sanctioning the Scheme of Arrangement to be duly
delivered to the Registrar and the Scheme of Arrangement shall become effective
as soon as a copy of the Court order sanctioning the Scheme of Arrangement has
been duly delivered to the Registrar for registration and the order and minutes
have been registered by him (the date of such registration being the "Scheme
Effective Date" and the time of such registration being the "Scheme Effective
Time").

     Notwithstanding the foregoing, if the Company and Amerada Hess so agree in
writing, and the same is consistent with any order of the Court sanctioning the
Scheme of Arrangement, the Company shall cause a copy of the order to be
delivered to the Registrar prior to the Scheme Closing, and the Scheme Closing
shall be held as soon as practicable thereafter, in which case the Scheme of
Arrangement shall become effective only after both a copy of the Court order
sanctioning the Scheme of Arrangement is delivered to the Registrar for
registration and the order and minutes have been registered by the Registrar and
the Scheme Closing shall have occurred. In such case, for all purposes, the
Scheme Effective Date shall be the date on which the Scheme Closing shall have
occurred and the Scheme Effective Time shall be the time at which the Scheme
Closing is deemed by the parties to be completed. As of the Scheme Effective
Time, the Company shall be a direct wholly owned subsidiary of the Purchaser.

     At the Scheme Effective Time, by virtue of the Scheme of Arrangement: (i)
each Ordinary Share issued and outstanding immediately prior to the Scheme
Effective Time (other than Ordinary Shares (and the associated Rights) which are
held by any wholly owned subsidiary of the Company or in the treasury of the
Company, or which are held, directly or indirectly, by Amerada Hess or any
subsidiary of Amerada Hess (including the Purchaser)) (the "Scheme Ordinary
Shares") shall be, by virtue of the Scheme of Arrangement and without any action
required by the holder thereof, transferred to the Purchaser in consideration
for $45.00 in cash per Scheme Ordinary Share transferred ("Ordinary Cash
Consideration") and (ii) in the event that there are Preferred Shares
outstanding on the commencement of the Scheme of Arrangement, each Preferred
Share issued and outstanding immediately prior to the Scheme Effective Time
(other than Preferred Shares which are held by any wholly owned subsidiary of
the Company or in the treasury of the Company, or which are held, directly or
indirectly, by Amerada Hess or any subsidiary of Amerada Hess (including the
Purchaser)) (the "Scheme Preferred Shares" and together with the Scheme Ordinary
Shares, the "Scheme Shares") shall be, by virtue of the Scheme of Arrangement
and without any action required by the holder thereof, transferred to the
Purchaser in consideration for $180.00 in cash per Scheme Preferred Share, plus
any accumulated and unpaid dividends thereon through the Scheme Effective Date
(the "Preferred Cash Consideration" and together with the Ordinary Cash
Consideration, the "Cash Consideration").

     At the Scheme Effective Time, regardless of whether a certificate for
Scheme Shares shall be surrendered for exchange, all certificates for Scheme
Shares shall be deemed canceled and the holders thereof shall cease to have any
rights by virtue thereof, other than to receive the Cash Consideration set forth
herein. All Cash Consideration paid upon the deemed cancellation of certificates
for Scheme Shares shall be deemed to have been paid in full satisfaction of all
rights pertaining to such Scheme Shares.

     Subject to and by virtue of the orders of the Court under Sections 86 and
87 of the Companies Law sanctioning the Scheme of Arrangement, the terms of the
Scheme of Arrangement and the provisions for cancellation or surrender of the
certificates representing the Scheme Shares shall be as set forth in the Scheme
of Arrangement.

     Prior to the Scheme Effective Time, Amerada Hess or the Purchaser shall
designate a bank or trust company reasonably satisfactory to the Company to act
as exchange agent in connection with the transactions contemplated hereby (the
"Exchange Agent"). At the Scheme Effective Time, Amerada Hess or the Purchaser
shall provide the Exchange Agent in immediately available funds in U.S. dollars
all funds necessary to pay the Cash Consideration (the "Payment Fund"). As soon
as possible after the Scheme Effective Time, and in no event later than five (5)
business days after the Scheme Effective Date, Amerada Hess or the
                                        37
   41

Purchaser shall, or shall cause the Exchange Agent, to send to each holder of
the Scheme Shares at the address appearing in the register of members of the
Company on the date immediately preceding the Scheme Effective Date a bank
cheque in immediately available funds in U.S. dollars representing each such
shareholder's Cash Consideration. The payment required to be sent by Amerada
Hess or the Purchaser, or the Exchange Agent on their behalf, to the
shareholders pursuant to the Scheme of Arrangement shall be sent by mail with
postage prepaid, addressed to the shareholders entitled thereto at their
respective registered address, and Amerada Hess and the Purchaser shall not be
responsible for any loss or delay in transmission posted. No interest shall be
paid or accrued on the Cash Consideration. Until monies held in the Payment Fund
are paid to the shareholders, Amerada Hess and the Purchaser shall cause the
Exchange Agent to invest the Payment Fund as directed by them. All earnings on
investments made with the Payment Fund shall be paid to Amerada Hess or, at its
direction, to the Purchaser. If for any reason the Payment Fund is inadequate to
pay the amounts to which shareholders are entitled, the Purchaser shall, and
Amerada Hess shall cause the Purchaser to, promptly restore such amount of
inadequacy to the Payment Fund, and in any event shall be fully liable for
payment thereof. Any portion of the Payment Fund that remains undistributed to
the shareholders for nine months after the Scheme Effective Time shall be
delivered to the Purchaser, upon demand, and any shareholder who has not
theretofor complied with the procedures to receive payment shall thereafter look
only to Amerada Hess for payment of its claim for Cash Consideration. The
Exchange Agent shall be entitled to deduct and withhold from the Cash
Consideration otherwise payable to any shareholder pursuant to this Agreement
such amounts as may be required to be deducted and withheld with respect to the
making of such payment under any law.

     COMPOSITION OF THE BOARD OF DIRECTORS.  The Acquisition Agreement provides
that, promptly upon the acceptance for payment of, and payment by the Purchaser
for, Ordinary Shares pursuant to the Offer, the Purchaser will be entitled to
designate up to such number of directors ("Amerada Hess Designees") on the Board
of Directors of the Company, rounded up to the next whole number, as will give
the Purchaser representation on the Board of Directors of the Company equal to
at least that number of directors that equals the product of the total number of
directors on the Board of Directors of the Company (giving effect to the
directors elected pursuant to this sentence) multiplied by a fraction, the
numerator of which shall be the number of votes represented by the Ordinary
Shares (determined on an as-converted basis assuming that all then-outstanding
Preferred Shares owned by Amerada Hess and the Purchaser are converted into
Ordinary Shares) beneficially owned by the Purchaser and Amerada Hess and the
denominator of which shall be the aggregate number of votes represented by the
Ordinary Shares (determined on an as-converted basis assuming that all
then-outstanding Preferred Shares are converted into Ordinary Shares) then
issued and outstanding, and the Company and its Board of Directors will, at such
time, take any and all such action necessary to cause Amerada Hess Designees to
be appointed to the Board of Directors of the Company in such class of directors
(if any) as will ensure the longest possible term for such Amerada Hess
Designees (including using commercially reasonable efforts to cause relevant
directors to resign and/or increasing the size of the Board of Directors of the
Company (subject to the limitations set forth in the Company's Memorandum of
Association and Articles of Association)). The Company has agreed to take all
action required to effect the election of such Amerada Hess Designees. Upon
acceptance for payment of Ordinary Shares pursuant to the Offer (the date
Ordinary Shares are first accepted for payment, the "Acceptance Date"), the
Company, if so requested, has agreed to use its commercially reasonable efforts
to cause persons designated by Amerada Hess to constitute the same percentage of
each committee of its Board of Directors, each Board of Directors of each
subsidiary and each committee of each such Board of Directors (in each case to
the extent of the Company's ability to elect such persons) as the percentage of
the full Board of Directors of the Company that the Amerada Hess Designees
constitutes. Notwithstanding the other provisions of the Acquisition Agreement,
the Company, Amerada Hess and the Purchaser have agreed to use their respective
commercially reasonable efforts to ensure that at least two of the members of
the Board of Directors will, at all times prior to: (i) if Amerada Hess or the
Purchaser requests a Scheme of Arrangement pursuant to the Acquisition
Agreement, the earlier to occur of (A) the Scheme Effective Time and (B) the
date on which (x) the Court declines to sanction the Scheme of Arrangement, (y)
the Company's shareholders do not approve the Scheme of Arrangement at any
meeting duly called for such purpose or (z) Amerada Hess and the Purchaser
abandon the Scheme of Arrangement; (ii) if Amerada Hess and the Purchaser are
required to effect a Compulsory

                                        38
   42

Acquisition pursuant to the Acquisition Agreement, the earlier to occur of (A)
the date of completion of the Compulsory Acquisition (the "Compulsory Completion
Date") and (B) the date on which (x) the Court, pursuant to an application made
by a dissenting shareholder, grants an order preventing the acquisition of the
applicant's shares pursuant to Section 88 of the Companies Law or (y) Amerada
Hess and the Purchaser abandon the Compulsory Acquisition; and (iii) the date
which is 30 business days after the Acceptance Date if Amerada Hess and the
Purchaser are not required to effect a Compulsory Acquisition pursuant to the
Acquisition Agreement and Amerada Hess or the Purchaser does not request a
Scheme of Arrangement pursuant to the Acquisition Agreement on or before such
date (the applicable date being referred to herein as the "Discontinuance
Date"); be persons who are directors of the Company on the date of the
Acquisition Agreement (the "Continuing Directors"); provided, that if there are
in office less than two Continuing Directors, the Board of Directors may cause
the person designated by the remaining Continuing Director or Continuing
Directors to fill such vacancy, and such person will be deemed to be a
Continuing Director for all purposes of the Acquisition Agreement, or if no
Continuing Directors then remain, the other directors of the Company then in
office will designate two persons to fill such vacancies who will not be
officers, employees or affiliates of the Company or Amerada Hess, and such
persons will be deemed to be Continuing Directors for all purposes of the
Acquisition Agreement. Following the election or appointment of the Amerada Hess
Designees pursuant to the Acquisition Agreement and prior to the Discontinuance
Date, any amendment of the Acquisition Agreement, any proposal to shareholders
to amend the Company's Memorandum of Association or Articles of Association, any
termination of the Acquisition Agreement by the Company, any extension by the
Company of the time for the performance of any of the obligations or other acts
of Amerada Hess and the Purchaser or waiver of any of the Company's rights
thereunder, and any other consent or action by the Company thereunder, requires
the concurrence of a majority of the Continuing Directors, if there are more
than two Continuing Directors, or the concurrence of one Continuing Director, if
there are two Continuing Directors. In connection therewith, the Acquisition
Agreement provides that the Continuing Directors may, on behalf and at the
expense of the Company, retain financial and legal advisors.

Company made by a third party to acquire all of the Shares pursuant to a tender

the members of the entire Board of Directors of the Company (based on the
written advice of an independent nationally recognized investment bank)
reasonably determines in good faith to have a higher value than the
consideration to be received by the shareholders of the Company (in their
capacity as such) than the transactions contemplated by the Acquisition
Agreement to the extent proposed to be modified by Amerada Hess, (ii) that is
reasonably capable of being consummated (taking into account, among other
things, all legal, financial, regulatory and other aspects of such proposal and
the identity of the person making such proposal) and (iii) that is not
conditioned on obtaining any financing.

     The Acquisition Agreement provides that, in addition to the obligations of

inquiry or proposal or with whom such discussions or negotiations are taking
place. The Company has agreed to keep Amerada Hess fully informed of the status
and material details (including amendments or proposed amendments) of any such
request or Acquisition Proposal and keep Amerada Hess fully informed as to the
material details of any information requested of or provided by the Company and

request, Acquisition Proposal, inquiry or proposal, and to provide to Amerada
Hess within one day of receipt thereof all written materials received by the
Company with respect thereto. The Company has also agreed to provide promptly to
Amerada Hess any non-public information concerning the Company provided to any
other person in connection with any Acquisition Proposal that was not previously
provided to Amerada Hess.

     The Acquisition Agreement provides that the Company will immediately
request each person who had, prior to the date thereof, executed a
confidentiality agreement in connection with its consideration of acquiring the
Company or any portion thereof, to return all confidential information furnished
to such person by or on behalf of the Company, and the Company has agreed to use
its commercially reasonable efforts to have such information returned.

extent permitted by applicable law indemnity agreements with certain directors
and officers. Notwithstanding the foregoing, in respect of any Continuing
Director, the provisions with respect to indemnification and exculpation from
liability set forth in the Company's Memorandum of Association and Articles of
Association, as in effect on the date of the Acquisition Agreement, shall not be
amended, repealed or otherwise modified for a period of six years from the
Discontinuance Date in any manner that would adversely affect the rights
thereunder of any Continuing Director, unless such modification is required by
law. In addition, pursuant to the Acquisition Agreement, for a period of six
years from the earliest of the Acceptance Date, the Compulsory Completion Date,
the Scheme Effective Time and the expiration of the Acquisition Agreement, (i)
the Company will maintain in effect the Company's current directors' and
officers' liability insurance as in effect on the date of the Acquisition
Agreement covering those persons who were covered on the date of the Acquisition
Agreement by the Company's directors' and officers' liability insurance policy
(the "Indemnified Parties"); provided, however, that the Company shall not be
required to expend in any one year an amount in excess of 150% of the annual
premiums currently paid by the Company for such insurance and provided, further,
that the Company may substitute other policies with at least the same coverage
containing terms and conditions that are no less advantageous, so long as the
substitution does not result in any gaps or lapses in coverage with respect to
matters occurring prior to the earliest of the Acceptance Date, the Compulsory
Completion Date, the Scheme Effective Date and the expiration of the Acquisition
Agreement, or (ii) at such time as Amerada Hess, directly or indirectly through
the Purchaser, owns the entire share capital of the Company, the Company or
Amerada Hess may cause Amerada Hess' directors' and officers' liability
insurance then in effect to cover the Indemnified Parties with respect to those
matters covered by the Company's directors' and officers' liability insurance
policy so long as the terms thereof are no less advantageous to the intended
beneficiaries thereof than the Company's current directors' and officers'
liability insurance covering the Indemnified Parties. The Acquisition Agreement
provides that, if the Company elects clause (i) of the previous sentence and
such directors' and officers' liability insurance is terminated or canceled
during such six-year period, then, at such time as Amerada Hess, directly or
indirectly through the Purchaser, owns the entire share capital of the Company,
will use all reasonable efforts to cause to be obtained as much directors' and
officers' insurance as can be obtained for the remainder of such period for an
annualized premium not in excess of the maximum premium specified above, on
terms and conditions no less advantageous to the Indemnified Parties than such
insurance that has expired.

     The Acquisition Agreement provides that the Company and, at any time that
Amerada Hess owns directly or indirectly the entire share capital of the
Company, Amerada Hess must indemnify all Indemnified Parties to the fullest
extent permitted by applicable law with respect to all acts and omissions
arising out of such individuals' services as officers, directors, employees or
agents of the Company or any of its subsidiaries or as trustees or fiduciaries
of any plan for the benefit of employees of the Company or any of its
subsidiaries, and occurring at or prior to the earliest of the Acceptance Date,
the Compulsory Completion Date, the Scheme Effective Date and the expiration of
the Acquisition Agreement, including, without limitation, the transactions
contemplated by the Acquisition Agreement. In the event any such Indemnified
Party is or becomes involved, in any capacity, in any action, proceeding or
investigation in connection with any matter, including, without limitation, the
transactions contemplated by the Acquisition Agreement, occurring prior to and
including the earliest of the Acceptance Date, the Compulsory Completion Date,
the Scheme Effective Date and the expiration of the Acquisition Agreement, the
Company, and at such time as Amerada Hess owns the entire share capital of the
Company, Amerada Hess from and after such date will pay, as incurred, such
Indemnified Party's reasonable legal and other expenses (including the cost of
any investigation and preparation) incurred in connection therewith.

                                        44

     CERTAIN EMPLOYEE BENEFITS.  Pursuant to the Acquisition Agreement, Amerada
Hess will take such action as may be necessary so that on and after the earlier
of the Compulsory Completion Date and the Scheme Effective Date and for one year
thereafter, officers and employees of the Company and its subsidiaries shall be
provided employee benefits, plans and programs which are no less favorable in
the aggregate than those generally available to similarly situated officers and
employees of Amerada Hess and its subsidiaries, except with respect to the
benefits available under a specified severance policy (the "Severance Policy").
For purposes of eligibility to participate and vesting in all benefits provided
to officers and employees, the officers and employees of the Company and its
subsidiaries will be credited with the same years of service as they were
credited with the Company and its subsidiaries. The Acquisition Agreement
provides that, upon termination of any health plan of the Company or any of its
subsidiaries, individuals who were officers or employees of the Company or its
subsidiaries at the earlier to occur of the Compulsory Completion Date or the
Scheme Effective Date will, if employed by the Company and its subsidiaries,
become eligible to participate in such health plans established by Amerada Hess
(or existing plans maintained by the Company that satisfy the terms of the
Acquisition Agreement). The Acquisition Agreement further provides that amounts
paid before the earlier to occur of the Compulsory Completion Date and the
Scheme Effective Date by officers and employees of the Company and its
subsidiaries under any health plans of the Company shall after such date be
taken into account in applying deductible and out-of-pocket limits applicable
under the health plans of Amerada Hess provided as of such date to the same
extent as if such amounts had been paid under such health plans of Amerada Hess.
Pursuant to the Acquisition Agreement, following the earlier to occur of the
Compulsory Completion Date and the Scheme Effective Date, Amerada Hess will
permit and will cause the Company to permit all individuals who are employees of
the Company and its subsidiaries immediately prior to such date to retain and
take any paid vacation days accrued but not taken or lost under the Company's
and its subsidiaries' vacation policies prior to such date, provided that such
vacation days are taken or paid in lieu of being taken within one year after
such date. The Company, Amerada Hess and the Purchaser also agree that, upon the
Acceptance Date, a "change in control," "change of control" or "consolidation"
as applicable, shall be deemed to have occurred in respect of certain employment
agreements, change in control agreements and severance agreements and other
employee benefit plans and agreements (collectively, the "Severance Protection
Plans") and each of the Company and Amerada Hess has agreed to administer and
perform its obligations under the Severance Protection Plans as if a "change in
control" or "change of control" has occurred as of the Acceptance Date,
notwithstanding any terms contained therein to the contrary. Pursuant to the
Acquisition Agreement, from and after the date on which the Purchaser becomes
the beneficial owner of securities of the Company representing 90% or more of
the votes entitled to vote in the election of directors of the Company, Amerada
Hess shall, jointly and severally with the Company, (i) be liable to pay and
perform the obligations of the Company under the Severance Protection Plans and
(ii) take such action as may be necessary to promptly pay any severance payments
or other amounts from time to time due thereunder. The Acquisition Agreement
also provides that from and after the Acceptance Date, the Company will, and
Amerada Hess will cause the Company to, maintain the Severance Policy in full
force and effect at least until the first anniversary of the Acceptance Date in
respect of all persons covered by the Severance Policy as of the Offer Closing.
Notwithstanding the foregoing, no current or former employee of the Company or
any of its affiliates has any right to employment or continued employment with
the Company or any affiliate following the Acceptance Date except as provided by
Amerada Hess.

     OPTIONS.  Pursuant to the Acquisition Agreement, the Company may provide
and, if requested by Amerada Hess, shall provide to the extent permitted by
applicable law and the applicable options and stock plans, that all outstanding
stock options and other rights to purchase Ordinary Shares (the "Options")
previously granted under any stock option or similar plan of the Company (the
"Stock Plans") or otherwise shall vest and be fully exercisable, effective
immediately prior to expiration of the Offer which results in an Acceptance Date
if the Option holder (i) tenders all Options held by such holder for exercise
(conditioned only upon occurrence of the Acceptance Date) and tenders and does
not withdraw all Ordinary Shares issued upon exercise of such Options in the
Offer or (ii) irrevocably surrenders all Options held by such holder to the
Company between the final expiration date (including any Subsequent Offering
Period) if an Acceptance Date occurs with respect to the Offer and the earlier
of the Compulsory Completion Date and the Scheme Effective Time for cancellation
in exchange for a cash option payment as provided in the Acquisition

                                        45
   49

Agreement. The Acquisition Agreement also provides that the Company may make
arrangements and, if requested by Amerada Hess, must make arrangements to permit
holders of Options to exercise conditionally their Options and tender all
Ordinary Shares issued upon exercise thereof in the Offer. The Company, Amerada
Hess and the Purchaser have agreed that the Purchaser will accept as validly
tendered pursuant to the Offer all Ordinary Shares which are to be issued
pursuant to the Conditional Option Exercise (as defined below). "Conditional
Option Exercise" means the exercise of all Options that are duly surrendered to
the Company for exercise, conditional only on the occurrence of the Acceptance
Date, and accompanied by appropriate irrevocable instructions that the Ordinary
Shares issuable upon such exercise shall be deemed to be exercised immediately
prior to the expiration of the Offer and properly tendered to the Purchaser
pursuant to the terms of the Offer and not withdrawn. From and after the
Acceptance Date until the earlier of the Compulsory Completion Date and the
Scheme Effective Time, the Company may permit, with Amerada Hess' prior
approval, and, if requested by Amerada Hess, shall permit, each holder of an
outstanding Option, in cancellation and settlement therefor, to receive payments
from the Company in cash equal to the product of (x) the total number of
Ordinary Shares subject to such Option, whether or not then vested or
exercisable, and (y) the amount by which the Ordinary Share Offer Price exceeds
the exercise price per Ordinary Share subject to such Option, to be paid upon
surrender to the Company of the Option and an appropriate surrender and release
agreement. The Exchange Agent shall be entitled to deduct and withhold from the
Cash Consideration otherwise payable such amounts as may be required to be
deducted and withheld with respect to the making of such payment under any law.
Pursuant to the Acquisition Agreement and subject to the rights of holders of
Options, the Board of Directors of the Company (or, if appropriate, any
committee thereof) will use its best efforts to obtain all necessary consents
and releases from all of the holders of all the outstanding Options, and will
use its best efforts, to the extent permitted without resulting in a breach or
violation thereof, to take all actions to (i) terminate, at the earlier of the
Compulsory Completion Date or the Scheme Effective Time, the Stock Plans and
Options and any other plan, program or arrangement providing for the issuance or
grant of any other interest in respect of the share capital of the Company or
any affiliate thereof and (ii) amend, as of the earlier of the Compulsory
Completion Date or the Scheme Effective Time and to the extent therein allowed,
the provisions of any other employee benefit plan providing for the issuance,
transfer or grant of any share capital of the Company or any such affiliate, or
any interest in respect of any share capital of the Company or any such
affiliate, to provide no continuing rights to acquire, hold, transfer or grant
any share capital of the Company or any such affiliate or any interest in the
share capital of the Company or any such affiliate.

     AGREEMENT TO USE COMMERCIALLY REASONABLE EFFORTS; FURTHER
ASSURANCES.  Pursuant to the Acquisition Agreement and subject to the terms and
conditions thereof, each of the Company, Amerada Hess and the Purchaser will,
and the Company will cause each of its subsidiaries to, cooperate and use their
commercially reasonable efforts to take, or cause to be taken, all appropriate
action, and do, or cause to be done, and assist and cooperate with the other
parties in doing, all things necessary, proper or advisable to consummate and
make effective, in the most expeditious manner practicable, the Offer and the
other transactions contemplated by the Acquisition Agreement, including the
satisfaction of the respective conditions summarized in the second paragraph
under the heading "Scheme of Arrangement" above, and to make, or cause to be
made, all filings necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated by
the Acquisition Agreement including their commercially reasonable efforts to
obtain all licenses, permits, consents, approvals, authorizations,
qualifications and orders of governmental entities and parties to contracts with
the Company and its subsidiaries as are necessary for consummation of the
transactions contemplated by the Acquisition Agreement and to fulfill the
conditions to the Offer and the Scheme of Arrangement, as the case may be.

     HSR ACT.  In addition, the Acquisition Agreement provides that the Company,
Amerada Hess and the Purchaser will (i) take promptly all actions necessary to
make the filings required of it or any of its affiliates under any applicable
antitrust laws in connection with the Acquisition Agreement and the transactions
contemplated thereby, including but not limited to filing pursuant to the HSR
Act no later than the tenth day following the date of the Acquisition Agreement
a Notification and Report Form with respect to the transactions contemplated by
the Acquisition Agreement, (ii) comply at the earliest practicable date with any
formal or informal request for additional information or documentary material
received by it or any of its
                                        46
   50

affiliates from any antitrust authority and (iii) cooperate with one another in
connection with any filing under applicable antitrust laws and in connection
with resolving any investigation or other inquiry concerning the transactions
contemplated by the Acquisition Agreement initiated by any antitrust authority.
Each party to the Acquisition Agreement has also agreed to use its commercially
reasonable efforts to resolve any objections that may be asserted with respect
to the transactions contemplated by the Acquisition Agreement under any
antitrust law. Finally, each party also agreed promptly to inform the other
parties of any material communication made to, or received by it from, any
antitrust authority or any other governmental entity regarding any of the
transactions contemplated by the Acquisition Agreement.

termination of the Acquisition Agreement, the Company shall not (i) redeem the
Rights, (ii) amend (other than to delay the Distribution Date) or to render the
Rights inapplicable to the Offer and the transactions contemplated by the
Transaction Documents or terminate the Rights Agreement prior to the Effective

take any action which would allow any person other than Amerada Hess or the

without causing a Distribution Date or a Share Acquisition Date.

     TERMINATION.  The Acquisition Agreement may be terminated at any time prior

shareholders: (a) by mutual consent of the Company, on the one hand, and of
Amerada Hess and the Purchaser, on the other hand; (b) by either Amerada Hess,
on the one hand, or the Company, on the other hand, if, (i) any court of
competent jurisdiction or any governmental entity shall have issued an order,
decree or ruling or taken any other action permanently restricting, enjoining,
restraining or otherwise prohibiting the acceptance for payment of, or payment
for, Shares pursuant to the Offer, the Scheme of Arrangement or a Compulsory
Acquisition, and such order, decree or ruling or other action shall have become
final and nonappealable, or (ii) the Scheme of Arrangement or a Compulsory
Acquisition has not occurred by June 30, 2002; provided, that this termination
right may not be asserted by any party whose breach of its representations,
warranties or agreements under the Acquisition Agreement, shall have resulted in
the failure of the Compulsory Completion Date or Scheme Effective Date to have
occurred; (c) by the Company at any time prior to the purchase of Shares
pursuant to the Offer, if: (i) (x) there shall be a breach of any representation
or warranty of Amerada Hess or the Purchaser in the Acquisition Agreement that
is qualified as to Material Adverse Effect, (y) there shall be a breach of any
representation or warranty of Amerada Hess or the Purchaser in the Acquisition
Agreement that is not so qualified, other than any such breaches which, in the
aggregate, have not had, do not have, or could not reasonably be expected to
have, a Material Adverse Effect on Amerada Hess, or (z) there shall be a
material breach by Amerada Hess or the Purchaser of any of their respective
covenants or agreements contained in the Acquisition Agreement, which breach, in
the case of clause (x), (y) or (z), either is not reasonably capable of being
cured or, if it is reasonably capable of being cured, has not been cured by the

the

                                        47
   51

Company is in material breach of the Acquisition Agreement, or (ii) (x) if the
Offer has not been timely commenced or (y) the Offer has expired without the
Purchaser purchasing any Ordinary Shares pursuant thereto and Amerada Hess or
the Purchaser has not requested the Company pursue a Scheme of Arrangement
within 10 business days of such expiration date, unless such failure or
expiration shall have been caused by the failure of the conditions set forth in
clause (iii)(c) or (d) of the Tender Offer Conditions; (d) by Amerada Hess at
any time prior to the purchase of Ordinary Shares pursuant to the Offer, if, (i)
the Offer is terminated or expires in accordance with its terms without the
Purchaser having purchased any Ordinary Shares pursuant thereto due to an
occurrence that would result in a failure to satisfy any one or more of the
Tender Offer Conditions, unless any such failure was caused by or resulted from
the failure of Amerada Hess or the Purchaser to perform in any material respect
any covenant or agreement of either of them contained in the Acquisition
Agreement or from the material breach by Amerada Hess or the Purchaser of any
representation or warranty of either of them contained in the Acquisition
Agreement, (ii) (x) there shall be a breach of any representation or warranty of
the Company in the Acquisition Agreement that is qualified as to Material
Adverse Effect, (y) there shall be a breach of any representation or warranty of
the Company in the Acquisition Agreement that is not so qualified, other than
any such breaches which, in the aggregate, have not had, do not have or could
not reasonably be expected to have a Material Adverse Effect on the Company, or
(z) there shall be a material breach by the Company of any of its covenants or
agreements contained in the Acquisition Agreement, which breach, in the case of
any of the clauses (x), (y) or (z), either is not reasonably capable of being
cured or, if it is reasonably capable of being cured, has not been cured by the
earlier of 10 days after the giving of written notice to the Company of such
breach and one business day prior to the expiration of the Offer; provided, that
Amerada Hess may not terminate the Acquisition Agreement pursuant to this clause
(d)(ii) if Amerada Hess or the Purchaser is in material breach of the
Acquisition Agreement, (iii) (x) the Company has (A) withdrawn, modified or
amended, in a manner adverse to Amerada Hess or the Purchaser, the approval,

Directors or any committee thereof shall have resolved to do any of the
foregoing, (iv) if there has been a breach by the Company of any provision
summarized under the heading -- "No Solicitation" hereof, or (v) the purchase
pursuant to the Offer of all Ordinary Shares tendered and not withdrawn (and at
least a number of Ordinary Shares equal to the minimum number of Ordinary Shares
required to be tendered to satisfy the Minimum Condition) has not occurred on or
before the final expiration date of the Offer, unless the purchase of Ordinary
Shares pursuant to the Offer has not occurred because of a material breach of
any representation, warranty, obligation, covenant, agreement or condition set
forth in the Acquisition Agreement on the part of Amerada Hess or the Purchaser;
or (e) by either Amerada Hess or the Company if (i) the Scheme of Arrangement is
not approved by the requisite vote of shareholders of the Company at a meeting
duly called for the purpose of voting on the Scheme of Arrangement, (ii) the
Court declines to sanction the Scheme of Arrangement, or (iii) Amerada Hess and

or the Company, on the other hand, pursuant to the provisions described above,
written notice thereof will be given to the other party or parties specifying
the provision of the Acquisition Agreement pursuant to which such termination is
made, and the Acquisition Agreement will become void and have no effect and
there shall be no liability thereunder on the part of the Company, Amerada Hess
or the Purchaser (except for breach of the Acquisition Agreement and the
survival of certain provisions, including, without limitation, confidentiality,
directors' and officers' indemnification and insurance, benefit plans and
employment agreements, fees and expenses, applicable law, specific enforcement,
waiver of jury trial and effect of termination). Nothing in the termination
provisions of the Acquisition Agreement shall relieve any party to the

   52

Acquisition Agreement, except as provided in the next sentence, all costs and
expenses incurred in connection with the Acquisition Agreement and the

heading -- "Termination" hereof, solely due to the Minimum Condition not having
been met at the time of such termination, and an Acquisition Proposal had become

of such termination, the Company enters into an agreement with respect to or
consummates any Acquisition Proposal or (y) paragraph (d)(ii), (d)(iii) or
(d)(iv) under the heading -- "Termination" hereof, or (ii) the Company in
accordance with paragraph (c)(ii)(y) under the heading -- "Termination" hereof,
unless resulting from a material breach by Amerada Hess or the Purchaser of any
covenant or agreement contained in the Acquisition Agreement, and an Acquisition
Proposal had become publicly known prior to the date of such termination, and,
within twelve months of such termination, the Company enters into an agreement
with respect to or consummates any Acquisition Proposal, or (iii) either the
Company or Amerada Hess pursuant to paragraphs (b)(ii) or (e) under the heading
- -- "Termination," unless resulting from a material breach by Amerada Hess or the
Purchaser of any covenant or agreement contained in the Acquisition Agreement,
and an Acquisition Proposal had become publicly known prior to the date of such
termination and, within twelve months of such termination, the Company enters
into an agreement with respect to or consummates any Acquisition Proposal, then
the Company shall (I) reimburse Amerada Hess in immediately available funds for
the out-of-pocket expenses of Amerada Hess and the Purchaser (including, without
limitation, printing fees, filing fees and fees and expenses of its legal and
financial advisors and all fees and expenses payable to any financing sources)
related to the Offer, the Acquisition Agreement, the Principal Shareholders
Agreement, the transactions contemplated thereby and any related financing in
the amount of $10,000,000 and (II) pay to Amerada Hess in immediately available
funds an amount equal to $130,000,000. The payments required to be made in the
preceding sentence shall be paid as follows: (A) in the case of clause (i)(y),
on the day next succeeding the date of such termination or (B) in the case of
clause (i)(x), clause (ii) or clause (iii), 50% of the amount shall be paid on
the date that the Company enters into an agreement with respect to such
Acquisition Proposal and the remaining 50% (or 100% if there is no such
agreement) shall be paid on the date of consummation of such Acquisition
Proposal.

     PRINCIPAL SHAREHOLDERS AGREEMENT.  THE FOLLOWING IS A SUMMARY OF THE
PRINCIPAL SHAREHOLDERS AGREEMENT. THE SUMMARY IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE PRINCIPAL SHAREHOLDERS AGREEMENT, (A COPY OF WHICH HAS BEEN
FILED WITH THE COMMISSION AS AN EXHIBIT TO THE SCHEDULE TO.) THE PRINCIPAL
SHAREHOLDERS AGREEMENT CAN BE INSPECTED AT, AND COPIES MAY BE OBTAINED FROM, THE
SAME PLACES AND IN THE MANNER SET FORTH IN SECTION 7 -- "CERTAIN INFORMATION
CONCERNING THE COMPANY."

     In connection with the execution of the Acquisition Agreement, the
Principal Shareholders, who beneficially own, in the aggregate, 1,733,573
Ordinary Shares and 5,058,685 Preferred Shares, have entered into the Principal
Shareholders Agreement with Amerada Hess, the Purchaser and the Company.

     TENDER OF SHARES.  The Principal Shareholders have agreed (a) in the case
of Ordinary Shares, tender validly (and not to withdraw unless instructed by the
Purchaser), or to cause to be tendered validly (and not withdrawn unless
instructed by the Purchaser) and (b) in the case of Preferred Shares, surrender
duly for conversion, conditional upon the Offer not being terminated, not
expiring, and the Purchaser accepting for payment Ordinary Shares in the Offer
and with appropriate instructions (which instructions shall be revoked only upon
the direction of the Purchaser) that the Ordinary Shares issuable upon such
conversion are to be tendered pursuant to the Offer immediately prior to the
expiration of the initial offering period of the Offer (including any extensions
thereof), in each case pursuant to and in accordance with the terms of the Offer
and Rule 14d-2 under the Exchange Act, not later than the third business day
after commencement of the Offer, all of the Ordinary Shares and Preferred Shares
owned by the Principal Shareholders and their affiliates (the Ordinary Shares
and the Preferred Shares, together with any other shares the beneficial
ownership of which is acquired by such Principal Shareholder or such Principal
Shareholder's affiliates during the period from and including the date of the
Principal Shareholders Agreement through and including the date on which the
Principal Shareholders Agreement is terminated, are collectively referred to as
the "Subject Shares") and, in

                                        49
   53

the case of Subject Shares acquired after the date of the Principal Shareholders
Agreement, the next succeeding business day after the acquisition of such
Subject Shares.

     The Principal Shareholders have also agreed to cause their Ordinary Shares
to remain validly tendered and not withdrawn and their Preferred Shares to
remain validly surrendered for conversion with appropriate tender instructions
until the earlier of (x) the Offer being terminated or expiring and the
Purchaser not accepting for payment all Ordinary Shares validly tendered in the
Offer and (y) Amerada Hess, in the case of Ordinary Shares, instructing such
Principal Shareholder to withdraw such Principal Shareholder's Ordinary Shares
or, in the case of Preferred Shares, instructing such Principal Shareholder to
revoke such Principal Shareholder's tender and conversion instructions, in which
case such Principal Shareholder shall immediately withdraw all Ordinary Shares
and revoke tender and conversion instructions with respect to the Preferred
Shares. The Principal Shareholders Agreement provides that, in the event that
any Ordinary Shares are for any reason withdrawn from the Offer or the tender
and conversion instructions relating to Preferred Shares are revoked, in either
case other than upon the instruction of the Purchaser, such Ordinary Shares and
Preferred Shares shall remain subject to the terms of the Principal Shareholders
Agreement, so long as the Principal Shareholders Agreement remains effective.
The obligation of the Purchaser to accept for payment and pay for the Ordinary
Shares in the Offer, including the Subject Shares, is subject to certain
conditions; provided, that the only conditions of Amerada Hess and the Purchaser
to purchase Subject Shares pursuant to the Principal Shareholders Agreement are
described in -- "Conditions to Sale" below. Pursuant to the Principal
Shareholders Agreement, the surrender for conversion of Preferred Shares on a
conditional basis shall not constitute a conversion until the conditions
relating thereto are satisfied or waived and the Company has agreed to waive any
and all notice or waiting period requirement with respect to a conversion of
such Preferred Shares.

     VOTING OF SHARES.  Each Principal Shareholder has agreed, until the
termination of the Principal Shareholders Agreement, to vote (or cause to be
voted) all of its, his or her Subject Shares at any meeting (or any adjournment
or postponement thereof) of the holders of any class or classes of the share
capital of the Company, however called, or in connection with any written
consent of the holders of any class or classes of the share capital of the
Company, (x) in favor of approval of the terms of the Acquisition Agreement and
each of the other transactions contemplated by the Acquisition Agreement and the
Principal Shareholders Agreement and any actions required in furtherance
thereof, (y) against any action, transaction or agreement that would result in a
breach in any respect of any covenant, representation or warranty or any other
obligation or agreement of the Company or any of its subsidiaries under the
Acquisition Agreement or of such Principal Shareholder under the Principal
Shareholders Agreement and (z) except as otherwise agreed to in writing in
advance by Amerada Hess, against the following actions (other than the
transactions contemplated by the Acquisition Agreement): (i) any extraordinary
corporate transaction, such as an amalgamation, merger, scheme of arrangement,
consolidation or other business combination involving the Company or any of its
subsidiaries and any Acquisition Proposal; (ii) a sale, lease or transfer of a
significant part of the assets of the Company or any of its subsidiaries, or a
reorganization, recapitalization, dissolution or liquidation of the Company or
any of its subsidiaries; and (iii) (A) any change in the persons who constitute
the Board of Directors of the Company; (B) any change in the capitalization of
the Company or any amendment of the Company's Memorandum of Association or the
Company's Articles of Association; (C) any other material change in the
Company's corporate structure or business; or (D) any other action involving the
Company or any of its subsidiaries that is intended, or could reasonably be
expected, to impede, interfere with, delay, postpone, or adversely affect the
transactions contemplated by the Principal Shareholders Agreement or the
Acquisition Agreement (the foregoing matters are referred to as the "Voting
Matters"). The Principal Shareholders have further agreed not to enter into any
agreement that violates or conflicts with the provisions of the Acquisition
Agreement or the Principal Shareholders Agreement.

     GRANT OF PROXY.  Each Principal Shareholder has also agreed to revoke all
prior proxies and have appointed Amerada Hess and the Purchaser and any designee
of Amerada Hess and the Purchaser, and each of them individually, with full
power of substitution and resubstitution, the Principal Shareholders' proxy and
attorney-in-fact during the term of the Principal Shareholders Agreement, to
vote all of the Principal Shareholders' Subject Shares on the Voting Matters.
The proxy is coupled with an interest sufficient in law to support an
irrevocable proxy and is irrevocable during the term of the Principal
Shareholders Agreement. The

                                        50
   54

power of attorney is durable and survives the dissolution, bankruptcy, death or
incapacity of the Principal Shareholder who granted it.

     PURCHASE AND SALE.  If the initial offering period (including any extension
thereof) has terminated or expired without the acceptance for purchase of each
Principal Shareholder's Ordinary Shares tendered in the Offer, each Principal
Shareholder has agreed to sell, and Amerada Hess has agreed to cause the
Purchaser, and the Purchaser has agreed to purchase, all of each Principal
Shareholder's Subject Shares. Pursuant to the Principal Shareholders Agreement,
the Purchaser has the right to purchase either the Preferred Shares or to cause
any Principal Shareholder to convert its, his or her Preferred Shares into
Ordinary Shares and purchase the Ordinary Shares so converted. The Principal
Shareholders Agreement provides that the purchase price shall be the greater of
(a) in the case of Ordinary Shares, $45.00 per Ordinary Share net to the
Principal Shareholder in cash and in the case of Preferred Shares, $180.00 per
Preferred Share, plus accumulated and unpaid dividends to the date of purchase,
net to the Principal Shareholder in cash and (b) in the case of Ordinary Shares,
the highest price paid per Ordinary Share in the Offer and, in the case of
Preferred Shares, the as-converted equivalent amount per Preferred Share as such
highest price paid per Ordinary Share in the Offer, plus accumulated and unpaid
dividends through the date of purchase. If the purchase of the Subject Shares
would take place during any Subsequent Offering Period being conducted pursuant
to the Offer, upon the request of Amerada Hess, each Principal Shareholder has
agreed immediately to tender such Principal Shareholder's Ordinary Shares
(including Ordinary Shares issuable upon conversion of Preferred Shares) into
the Offer.

     CONDITIONS TO SALE.  The Principal Shareholders Agreement provides that the
Purchaser is not required to purchase any Subject Shares if the Subject Shares
shall have been purchased pursuant to the Offer, any applicable waiting period
(and any extension thereof) under the antitrust laws shall not have expired or
been terminated, or if, at any time on or after the date of the Principal
Shareholders Agreement and at or before the time of payment for any Subject
Shares, any of the following shall exist: (a) there shall be threatened,
instituted or pending any action or proceeding by any governmental entity, (i)
challenging or seeking to, or which could reasonably be expected to, make
illegal, impede, delay or otherwise directly or indirectly restrain, prohibit or
make materially more costly the transactions contemplated by the Principal
Shareholders Agreement, (ii) seeking to prohibit or materially limit the
ownership or operation by Amerada Hess or the Purchaser of all or any material
portion of the business or assets of the Company and its subsidiaries taken as a
whole or to compel Amerada Hess or the Purchaser to dispose of or hold
separately all or any material portion of the business or assets of Amerada Hess
and its subsidiaries taken as a whole, or the Company and its subsidiaries taken
as a whole, or seeking to impose any limitation on the ability of Amerada Hess
or the Purchaser to conduct its business or own such assets, (iii) seeking to
impose limitations on the ability of Amerada Hess or the Purchaser effectively
to exercise full rights of ownership of the Subject Shares, including, without
limitation, the right to vote any Subject Shares acquired or owned by the
Purchaser or Amerada Hess on all matters properly presented to the Company's
shareholders (other than voting restrictions under applicable law in effect on
the date of the Principal Shareholders Agreement), (iv) seeking to require
divestiture by Amerada Hess or the Purchaser of any Subject Shares or (v)
otherwise directly or indirectly relating to the transactions contemplated by
the Principal Shareholders Agreement and that could reasonably be expected to
have a Material Adverse Effect on the Company and its subsidiaries taken as a
whole or on Amerada Hess and its subsidiaries taken as a whole; (b) there shall
be any action taken, or any statute, rule, regulation, legislation,
interpretation, judgment, order or injunction proposed, enacted, enforced,
promulgated, amended or issued after the date of the Principal Shareholders
Agreement and applicable to or deemed applicable to (i) Amerada Hess, the
Purchaser, the Company or any subsidiary of the Company or (ii) the transactions
contemplated by the Principal Shareholders Agreement, by any governmental
entity, other than the routine application of the waiting period provisions of
the HSR Act to the transactions contemplated by the Principal Shareholders
Agreement, that could reasonably be expected to result directly or indirectly in
any of the consequences referred to in the preceding paragraph; (c) except for
inaccuracies in any representations or warranties of the Principal Shareholders
that result from actions or inactions required by the Principal Shareholders
Agreement, any representation or warranty of the Principal Shareholders and the
Company contained in the Principal Shareholders Agreement shall not be
materially true and correct as of the closing of the purchase of the Subject
Shares; or (d) any Principal Shareholder or the Company shall have failed to
                                        51
   55

perform in any material respect any obligation or to comply in any material
respect with any agreement or covenant under the Principal Shareholders
Agreement.

     COVENANTS.  The Principal Shareholders have agreed not to (i) sell,
transfer, tender, pledge, encumber, assign or otherwise dispose of, or enter
into any contract, option or other agreement with respect to, or consent to, the
sale, transfer, tender, pledge, encumbrance, assignment or other disposition of
their Subject Shares, except in accordance with the Acquisition Agreement and
the Principal Shareholders Agreement, (ii) grant any proxies or powers of
attorney with respect to their Subject Shares, or deposit their Subject Shares
into a voting trust or enter into a voting agreement with respect to their
Subject Shares, deposit any Subject Shares into any voting trust or enter into
any voting agreement with respect to any Subject Shares or (iii) take any action
that would have the effect of preventing or disabling such Principal Shareholder
from performing its obligations under the Principal Shareholders Agreement. The
Principal Shareholders have agreed not to convert or cause their affiliates to
convert any Preferred Shares, conditionally or otherwise, other than as
described under -- "Tender of Shares" or -- "Purchase and Sale" above, and have
agreed to convert their Preferred Shares upon the request of Parent. The
Principal Shareholders have agreed to convert immediately any or all of their
Subject Shares upon the request of Amerada Hess; provided, that all of the
conditions under -- "Conditions to Sale" have been satisfied or waived and
Amerada Hess or the Purchaser purchases such Ordinary Shares within three
business days thereafter.

     COVENANT AGAINST SOLICITATION OF OTHER OFFERS.  Pursuant to the Principal
Shareholders Agreement each Principal Shareholder has agreed, and has agreed to
use its commercially reasonable efforts to cause its affiliates and each of its
and their respective officers, directors, employees, representatives,
consultants, investment bankers, attorneys, accountants and other agents,
immediately to, cease any discussions or negotiations with any other person or
persons that may be ongoing with respect to any Acquisition Proposal. Each has
also agreed not to take and to use its commercially reasonable efforts to cause
its affiliates and their respective officers, directors, employees,
representatives, consultants, investment bankers, attorneys, accountants or
other agents or affiliates not to take any action (i) to encourage, solicit,
initiate or facilitate, directly or indirectly, the making or submission of any
Acquisition Proposal (including, without limitation, by taking any action that
would make the Rights Agreement inapplicable to an Acquisition Proposal), (ii)
to enter into any agreement, arrangement or understanding with respect to any
Acquisition Proposal, or to agree to approve or endorse any Acquisition Proposal
or enter into any agreement, arrangement or understanding that would require the
Company to abandon, terminate or fail to consummate any transaction contemplated
by the Principal Shareholders Agreement or the Acquisition Agreement, (iii) to
initiate or participate in any way in any discussions or negotiations with, or
furnish or disclose any information to, any person (other than Amerada Hess or
the Purchaser) in connection with any Acquisition Proposal, (iv) to facilitate
or further in any other manner any inquiries or the making or submission of any
proposal that constitutes, or may reasonably be expected to lead to, any
Acquisition Proposal or (v) to grant any waiver or release under any standstill,
confidentiality or similar agreement entered into by the Company or any of its
affiliates or representatives. Each Principal Shareholder has agreed to use its
commercially reasonable efforts to enforce, to the fullest extent permitted
under applicable law, the provisions of any standstill, confidentiality or
similar agreement entered into by such Principal Shareholder or any of its
affiliates or representatives including, but not limited to, where necessary
obtaining injunctions to prevent any breaches of such agreements and to enforce
specifically the terms and provisions thereof in any court having jurisdiction.

     INVESTOR RIGHTS AGREEMENT.  HM4 Triton, L.P. has agreed to take all actions
necessary under the Shareholders Agreement dated as of September 30, 1998 by and
between the Company and HM4 Triton, L.P., as amended on January 20, 1999 and
July 9, 2001 (the "Investor Rights Agreement") to effectuate the consummation of
the transactions contemplated by the Principal Shareholders Agreement and the
Acquisition Agreement and to refrain from taking any action, granting any
consent or otherwise exercising any rights under the Investor Rights Agreement
and to refrain from amending, or agreeing to amend, any provision of the
Investor Rights Agreement without the prior written consent of Amerada Hess. The
Company has also waived any right of first offer, right to purchase Shares,
right to notice or other right it may be provided under the Investor Rights
Agreement that may be triggered as a consequence of the Principal Shareholders
Agreement or the Acquisition Agreement or the consummation of the transactions
contemplated by the Principal

                                        52
   56

Shareholders Agreement or the Acquisition Agreement and to refrain from
amending, or agreeing to amend, any provision of the Investor Rights Agreement
without the prior written consent of Amerada Hess.

     COMPLIANCE WITH LAW.  The Principal Shareholders, Amerada Hess and the
Purchaser have agreed to comply with all applicable laws, including without
limitations, to prepare and promptly (but in no event later than ten business
days following the date of the Principal Shareholders Agreement) file all
necessary applications under HSR Act with respect to the purchase of the Subject
Shares pursuant to the Principal Shareholders Agreement.

     REPRESENTATIONS AND WARRANTIES.  The Principal Shareholders have made
customary representations and warranties in the Principal Shareholders Agreement
relating to due organization, ownership of shares, no conflicts, no finder's
fees, no encumbrances, reliance by Amerada Hess and the Investor Rights
Agreement. The Company has also made customary representations and warranties
relating to no adjustment to the conversion price of the Preferred Shares and
the Investor Rights Agreement. Amerada Hess and the Purchaser have made
customary representations and warranties relating to due organization, no
conflicts, investment intent, no finder's fees, litigation, ownership of the
Purchaser and reliance by Principal Shareholders.

     FIDUCIARY DUTIES.  The Principal Shareholders Agreement provides that
nothing therein shall limit or affect any actions taken by any Principal
Shareholder in his or her capacity as an officer or director of the Company.

     TERMINATION.  The Principal Shareholders Agreement may be terminated by (a)
the mutual written consent of Amerada Hess, the Purchaser and HM4 Triton, L.P.,
(b) any of Amerada Hess, the Purchaser or HM4 Triton, L.P. if the Subject Shares
have not been acquired by the Purchaser on or prior to December 31, 2001 or (c)
by HM4 Triton, L.P. if the Purchaser is in material breach of its obligations
under -- "Purchase and Sale" above; provided, that no party that is in material
breach of the Principal Shareholders Agreement may terminate the Principal
Shareholders Agreement.

     NO RECOURSE.  The partners, members, officers, directors, shareholders and
affiliates of a Principal Shareholder shall not have any personal liability or
obligation or to any person arising under the Principal Shareholder Agreement in
such capacities. Each Principal Shareholder's liability under the Principal
Shareholders Agreement shall be several and not joint and in all events shall be
limited with respect to each Principal Shareholder to the amount of cash
consideration actually received by such Principal Shareholder in the Offer or
pursuant to the Principal Shareholders Agreement in respect of such Principal
Shareholder's Ordinary Shares and Preferred Shares.

     CONFIDENTIALITY AGREEMENT.  THE FOLLOWING IS A SUMMARY OF THE
CONFIDENTIALITY AGREEMENT, DATED AS OF JUNE 4, 2001, BETWEEN AMERADA HESS AND
THE COMPANY (THE "CONFIDENTIALITY AGREEMENT"). THE SUMMARY IS QUALIFIED IN ITS
ENTIRETY BY REFERENCE TO THE CONFIDENTIALITY AGREEMENT, A COPY OF WHICH HAS BEEN
FILED WITH THE COMMISSION AS AN EXHIBIT TO THE SCHEDULE TO. THE CONFIDENTIALITY
AGREEMENT CAN BE INSPECTED AT, AND COPIES MAY BE OBTAINED FROM, THE SAME PLACES
AND IN THE MANNER SET FORTH IN SECTION 7 -- "CERTAIN INFORMATION CONCERNING THE
COMPANY."

     Pursuant to the Confidentiality Agreement, Amerada Hess and the Company
have agreed that certain information disclosed by the parties to each other will
be used solely for the purpose of the transactions contemplated by the
Acquisition Agreement, and that such information will be kept strictly
confidential by the recipient and those of its directors, officers, employees,
counsel, affiliates, agents, auditors, accountants or other advisors to whom
disclosure is necessary for the purpose of such an evaluation. Amerada Hess and
the Company have agreed that, for a period of one year from the date of the
Confidentiality Agreement, neither of them will, directly or indirectly, without
the prior written consent of the other: (a) in any manner acquire, agree to
acquire or make any proposal to acquire, directly or indirectly, any securities,
assets or property of the other party, other than purchases of the common shares
of the other party through employee pension plans, savings plans and similar
purchases in the ordinary course of business totaling less than 5% of the issued
and outstanding common shares of the other party and not for the purpose of
attempting to gain control of or influence the management, board of directors or
policies of the other party; (b) propose to enter into, directly

                                        53
   57

or indirectly, any merger or other business combination involving the other
party; (c) make, or in any way participate, directly or indirectly, in any
"solicitation" of "proxies" (as such terms are used in the proxy rules of the
Commission) to vote, or seek to advise or influence any person with respect to
the voting of, any voting securities of the other party; (d) form, join or in
any way participate in a "group" (within the meaning of Section 13(d)(3) of the
Exchange Act) with respect to any voting securities of the other party; (e)
otherwise act, alone or in concert with others, to seek to control or influence
the management, board of directors or policies of the other party; (f) disclose
any intention, plan or arrangement inconsistent with the foregoing; or (g)
advise, encourage, provide assistance (including financial assistance) to or
hold discussions with any other persons in connection with any of the foregoing.
Amerada Hess and the Company have agreed that they will not knowingly, as a
result of information or knowledge obtained from the other party pursuant to the
Confidentiality Agreement, solicit, entice or induce any employees of the other
party or its affiliates to become employed by such party or any affiliate, for a
period of two years from the date of the Confidentiality Agreement.

     12.  DIVIDENDS AND DISTRIBUTIONS.  As described above, the Acquisition
Agreement provides that, subject to certain exceptions, the Company shall not,
and shall not permit any of its subsidiaries to, without the prior written
consent of Amerada Hess, (i) declare, set aside or pay any dividends on, or make
any other actual, constructive or deemed distributions in respect of, any of its
capital stock, or otherwise make any payments to shareholders of the Company in
their capacity as such, other than (a) dividends payable to the Company declared
by any of the Company's wholly owned subsidiaries and (b) payments of regularly
scheduled dividends on the Preferred Shares, payment of dividends upon the
redemption of the Preferred Shares and the redemption of the Preferred Shares,
all in accordance with the terms of the Preferred Shares, (ii) split, combine or
reclassify any of its capital stock or issue or authorize the issuance of any
other securities in respect of, in lieu of or in substitution for shares of its
capital stock or (iii) except for the redemption of the Preferred Shares in
accordance with their terms purchase, redeem or otherwise acquire any shares of
capital of the Company or any of its subsidiaries or any other securities
thereof or any rights, warrants or options to acquire any such shares or other
securities.

     13.  EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; EXCHANGE ACT
REGISTRATION.

     MARKET FOR ORDINARY SHARES.  The purchase of Ordinary Shares pursuant to
the Offer will reduce the number of Ordinary Shares that might otherwise trade
publicly and could adversely affect the liquidity and market value of the
remaining Ordinary Shares held by the public.

     STOCK QUOTATION.  The Ordinary Shares are listed on the NYSE. Depending on
the number of Ordinary Shares purchased pursuant to the Offer, the Ordinary
Shares may no longer meet the published requirements for continued listing on
the NYSE and may therefore be delisted from the NYSE. According to the NYSE's
published guidelines, the NYSE would consider delisting the Ordinary Shares if,
among other things, (i) the number of Holders (including beneficial holders of
Ordinary Shares held in the names of NYSE member organizations in addition to
holders of record) should fall below 1,200 and the average monthly trading value
of Ordinary Shares for the most recent 12 months should be less than 100,000
Ordinary Shares, (ii) the number of publicly held Ordinary Shares should fall
below 600,000 (exclusive of the holdings of officers, directors or their
immediate families and other concentrated holdings of 10% or more), (iii) the
aggregate market value of publicly held Ordinary Shares should drop below
$8,000,000 (exclusive of the holdings of officers, directors or their immediate
families and other concentrated holdings of 10% or more), (iv) the Ordinary
Shares are no longer registered under the Exchange Act, as described below or
(v) the number of Holders (including beneficial holders of Ordinary Shares held
in the names of NYSE members organizations in addition to holders of record)
should fall below 400.

     If the NYSE were to delist the Ordinary Shares, it is possible that the
Ordinary Shares would continue to trade on other securities exchanges or in the
over-the-counter market and that price quotations would be reported by such
exchanges or through the Nasdaq Stock Market, Inc.'s National Market System
("Nasdaq") or other sources. However, the extent of the public market for the
Ordinary Shares and the availability of such quotations would depend upon such
factors as the number of shareholders and/or the aggregate market value of the
Ordinary Shares remaining at such time, the interest in maintaining a market in

                                        54
   58

the Ordinary Shares on the part of securities firms, the possible termination of
registration under the Exchange Act (as described below) and other factors.

     EXCHANGE ACT REGISTRATION.  The Ordinary Shares are currently registered
under the Exchange Act. Such registration under the Exchange Act may be
terminated upon application of the Company to the Commission if the Ordinary
Shares are neither listed on a national securities exchange nor held by 300 or
more holders of record. Termination of registration under the Exchange Act would
substantially reduce the information required to be furnished by the Company to
its shareholders and to the Commission and would make certain provisions of the
Exchange Act no longer applicable to the Company, such as the short-swing profit
recovery provisions of Section 16(b) of the Exchange Act, the requirement of
furnishing a proxy statement pursuant to Section 14(a) of the Exchange Act in
connection with shareholders' meetings, the related requirement of furnishing an
annual report to shareholders and the requirements of Rule 13e-3 under the
Exchange Act with respect to "going private" transactions. Furthermore, the
ability of "affiliates" of the Company and persons holding "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144
promulgated under the Securities Act of 1933, as amended, may be impaired or
eliminated. The Purchaser intends to seek to cause the Company to apply for
termination of registration of the Ordinary Shares under the Exchange Act as
soon after the completion of the Offer as the requirements for such termination
are met.

     If registration of the Ordinary Shares is not terminated prior to the
consummation of the Compulsory Acquisition or the Scheme of Arrangement, then
the Ordinary Shares will be delisted from all stock exchanges and the
registration of the Ordinary Shares under the Exchange Act will be terminated
following the consummation of the Compulsory Acquisition or the Scheme of
Arrangement.

     MARGIN REGULATIONS.  The Ordinary Shares are currently "margin securities,"
as such term is defined under the regulations of the Federal Reserve Board,
which has the effect, among other things, of allowing brokers to extend credit
on the collateral of the Ordinary Shares. Depending upon factors similar to
those described above regarding listing and market quotations, it is possible
that, following the Offer, the Ordinary Shares would no longer constitute
"margin securities" for the purposes of the margin regulations of the Federal
Reserve Board and therefore could no longer be used as collateral for loans made
by brokers. In any event, the Ordinary Shares will cease to be "margin
securities" if registration of the Ordinary Shares under the Exchange Act is
terminated.

     14.  CONDITIONS OF THE OFFER.  Notwithstanding any other provision of the
Offer or the Acquisition Agreement, the Purchaser shall not be required to
accept for payment or, subject to any applicable rules and regulations of the
Commission, including Rule 14e-1(c) under the Exchange Act (relating to the
Purchaser's obligation to pay for or return tendered Ordinary Shares promptly
after termination or withdrawal of the Offer), to pay for any Ordinary Shares
tendered pursuant to the Offer and may terminate or amend the Offer and may
postpone the acceptance of, and payment for, any Ordinary Shares, if (i) the
Minimum Condition shall not have been satisfied, (ii) any applicable waiting
period (and any extension thereof) under the HSR Act shall not have expired or
been terminated or (iii) if, at any time on or after the date of the Acquisition
Agreement and at or before the time of payment for any Ordinary Shares (whether
or not any Ordinary Shares have theretofore been accepted for payment, or paid
for, pursuant to the Offer) any of the following shall exist:

          (a) there shall be threatened, instituted or pending any action or
     proceeding by any Governmental Entity, (i) challenging or seeking to, or
     which could reasonably be expected to, make illegal, impede, delay or
     otherwise directly or indirectly restrain, prohibit or make materially more
     costly the Offer, the Compulsory Acquisition or the Scheme of Arrangement
     or any other transaction contemplated by the Acquisition Agreement or the
     Principal Shareholders Agreement (each, a "Transaction"), (ii) seeking to
     prohibit or materially limit the ownership or operation by Amerada Hess or
     the Purchaser of all or any material portion of the business or assets of
     the Company and its subsidiaries taken as a whole or to compel Amerada Hess
     or the Purchaser to dispose of or hold separately all or any material
     portion of the business or assets of Amerada Hess and its subsidiaries
     taken as a whole or the Company and its subsidiaries taken as a whole, or
     seeking to impose any limitation on the ability of Amerada Hess or the

                                        55
   59

     Purchaser to conduct its business or own such assets, (iii) seeking to
     impose limitations on the ability of Amerada Hess or the Purchaser
     effectively to exercise full rights of ownership of the Shares, including,
     without limitation, the right to vote any Shares acquired or owned by the
     Purchaser or Amerada Hess on all matters properly presented to the
     Company's shareholders, (iv) seeking to require divestiture by Amerada Hess
     or the Purchaser of any Shares, (v) seeking any material diminution in the
     benefits expected to be derived by Amerada Hess or the Purchaser as a
     result of the transactions contemplated by the Acquisition Agreement or the
     Principal Shareholders Agreement, or (vi) otherwise directly or indirectly
     relating to any Transaction and which could reasonably be expected to have
     a Material Adverse Effect on the Company and its subsidiaries taken as a
     whole or on Amerada Hess and its subsidiaries as a whole;

          (b) there shall be any action taken, or any statute, rule, regulation,
     legislation, interpretation, judgment, order or injunction proposed,
     enacted, enforced, promulgated, amended or issued after July 9, 2001 and
     applicable to or deemed applicable to (i) Amerada Hess, the Purchaser, the
     Company or any subsidiary of the Company or (ii) the Offer or the Scheme of
     Arrangement or any Transaction, by any Governmental Entity other than the
     routine application of the waiting period provisions of the HSR Act to the
     Offer, any Transaction or to the Scheme of Arrangement, that could
     reasonably be expected to result directly or indirectly in any of the
     consequences referred to in paragraph (a) above;

          (c) except for inaccuracies in any representations or warranties of
     the Company that result from actions or inactions required by the
     Acquisition Agreement, (i) any representation or warranty of the Company
     contained in the Acquisition Agreement that is qualified as to Material
     Adverse Effect shall not be true and correct as though made on or as of
     such date (other than representations and warranties which, by their terms,
     address matters only as of another specified date, which shall be true and
     correct only as of such other specified date), and (ii) any representations
     or warranties of the Company contained in the Acquisition Agreement that is
     not qualified as to Material Adverse Effect shall not be true and correct
     (except where the failure of any such representations or warranties
     referred to in this clause (ii) to be so true and correct in the aggregate
     has not had, does not have, and could not reasonably be expected to have, a
     Material Adverse Effect on the Company), as of the date of consummation of
     the Offer as though made on or as of such date (other than representations
     and warranties which, by their terms, address matters only as of another
     specified date, which shall be true and correct only as of such other
     specified date);

          (d) the Company shall have failed to perform in any material respect
     any obligation or to comply in any material respect with any agreement or
     covenant of the Company to be performed or complied with by the Company
     under the Acquisition Agreement;

          (e) the Board of Directors of the Company or any committee thereof
     shall (i) have withdrawn, modified or amended, or proposed to withdraw,
     modify or amend, in a manner adverse to Amerada Hess or the Purchaser, the
     approval, adoption or recommendation, as the case may be, of the Offer, any
     Transaction, the Scheme of Arrangement or the Acquisition Agreement, or
     (ii) shall have approved or recommended, or proposed to approve or
     recommend, any Acquisition Proposal, or (iii) shall have announced a
     neutral position with respect to any Acquisition Proposal and has not
     rejected such Acquisition Proposal within three business days of the
     announcement of such neutral position, or (iv) shall have resolved to do
     any of the foregoing; or

          (f) the Acquisition Agreement shall have been terminated in accordance
     with its terms;

which, in the sole judgment of the Purchaser, in any such case and regardless of
the circumstances (including any action or inaction by Amerada Hess or the
Purchaser) giving rise to any such condition, makes it inadvisable to proceed
with the Offer and/or with such acceptance for payment of, or payment for,
Ordinary Shares.

     "Governmental Entity" shall mean any domestic or foreign court, arbitral
tribunal, administrative agency or commission or other governmental or
regulatory agency or authority or any securities exchange.

                                        56
   60

     "Material Adverse Effect," with respect to any person, shall mean any
event, change, occurrence, effect, fact, violation or circumstance having a
material adverse effect on (i) the ability of such person to perform its
obligations under the Acquisition Agreement or to consummate the transactions
contemplated thereby on a timely basis or (ii) the business, assets,
liabilities, results of operations or condition (financial or otherwise) of such
person and its subsidiaries, taken as a whole; provided, however, that effects
relating to (x) the economy in general, (y) changes in oil, gas or other
hydrocarbon commodity prices or other changes affecting the oil and gas industry
generally or (z) the announcement of the transactions contemplated by the
Acquisition Agreement shall be deemed to not constitute a "Material Adverse
Effect" or be considered in determining whether a "Material Adverse Effect" has
occurred.

     The foregoing conditions are for the sole benefit of Amerada Hess and the
Purchaser and may be asserted by Amerada Hess or the Purchaser, or may be waived
by Amerada Hess or the Purchaser, in whole or in part at any time and from time
to time in their respective sole discretion, except as otherwise provided in the
Acquisition Agreement. The failure by Amerada Hess or the Purchaser at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time.

     15.  CERTAIN LEGAL MATTERS; REGULATORY APPROVALS.

     GENERAL.  Except as otherwise disclosed herein, neither Amerada Hess nor
the Purchaser is aware of (i) any license or regulatory permit that appears to
be material to the business of the Company and its subsidiaries, taken as a
whole, that might be adversely affected by the acquisition of Ordinary Shares by
the Purchaser pursuant to the Offer, the Compulsory Acquisition, the Scheme of
Arrangement or otherwise or (ii) any approval or other action by any
governmental, administrative or regulatory agency or authority, domestic or
foreign, that would be required for the acquisition or ownership of Ordinary
Shares by the Purchaser as contemplated herein. Should any such approval or
other action be required, the Purchaser currently contemplates that it would
seek such approval or action. The Purchaser's obligation under the Offer to
accept for payment and pay for Ordinary Shares is subject to certain conditions.
See Section 14 -- "Conditions of the Offer." While, except as described in this
Offer to Purchase, the Purchaser does not currently intend to delay the
acceptance for payment of Ordinary Shares tendered pursuant to the Offer pending
the outcome of any such matter, there can be no assurance that any such approval
or action, if needed, would be obtained or would be obtained without substantial
conditions or that adverse consequences might not result to the business of the
Company, Amerada Hess or the Purchaser or that certain parts of the businesses
of the Company, Amerada Hess or the Purchaser might not have to be disposed of
in the event that such approvals were not obtained or any other actions were not
taken.

     TAKEOVER LAWS.  The Company is incorporated under the laws of the Cayman
Islands. For a discussion of the Companies Law provisions applicable to the
Compulsory Acquisition or the Scheme of Arrangement, see Section 11 -- "Purpose
of the Offer; Plans for the Company; Certain Agreements." Based on
representations made by the Company in the Acquisition Agreement, the Purchaser
does not believe that any takeover statutes apply to the Offer, the Compulsory
Acquisition or the Scheme of Arrangement. Neither Amerada Hess nor the Purchaser
has currently complied with any takeover statute or regulation. The Purchaser
reserves the right to challenge the applicability or validity of any law
purportedly applicable to the Offer, the Compulsory Acquisition or the Scheme of
Arrangement and nothing in this Offer to Purchase or any action taken in
connection with the Offer, the Compulsory Acquisition or the Scheme of
Arrangement is intended as a waiver of such right. In the event it is asserted
that one or more takeover laws is applicable to the Offer, the Compulsory
Acquisition or the Scheme of Arrangement, and an appropriate court does not
determine that it is inapplicable or invalid as applied to the Offer, the
Compulsory Acquisition or the Scheme of Arrangement, as applicable, the
Purchaser might be required to file certain information with, or receive
approvals from, the relevant governmental authorities. In addition, if enjoined,
the Purchaser might be unable to accept for payment any Ordinary Shares tendered
pursuant to the Offer, or be delayed in continuing or consummating the Offer and
the Compulsory Acquisition or the Scheme of Arrangement. In such case, the
Purchaser may not be obligated to accept for payment any Ordinary Shares
tendered. See Section 14 -- "Conditions of the Offer."

     APPRAISAL RIGHTS.  No appraisal rights are available to Holders in
connection with the Offer. Dissenting Shareholders may have certain rights in
connection with a Compulsory Acquisition. See Section 11 -- "Purpose of the
Offer; Plans for the Company; Certain Agreements."

     GOING PRIVATE TRANSACTIONS.  Rule 13e-3 under the Exchange Act is
applicable to certain "going private" transactions. The Purchaser does not
believe that Rule 13e-3 will be applicable to the Compulsory Acquisition or the
Scheme of Arrangement, unless, among other things, the Compulsory Acquisition or
the Scheme of Arrangement is completed more than one year after termination of
the Offer. If applicable, Rule 13e-3 would require, among other things, that
certain financial information regarding the Company and certain information
regarding the fairness of the Compulsory Acquisition or the Scheme of
Arrangement and the consideration offered to shareholders of the Company therein
be filed with the Commission and disclosed to shareholders of the Company prior
to consummation of the Compulsory Acquisition or the Scheme of Arrangement.

     REGULATORY APPROVALS.  Under the HSR Act and the rules that have been
promulgated thereunder by the Federal Trade Commission ("FTC"), certain
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 Ordinary Shares by the Purchaser pursuant to the
Offer is subject to the HSR Act requirements.

     Under the provisions of the HSR Act applicable to the purchase of Ordinary
Shares pursuant to the Offer, such purchase may not be made until the expiration
of a fifteen calendar day waiting period following the required filing of a
Notification and Report Form under the HSR Act by Amerada Hess which Amerada
Hess expects to submit on or about July 19, 2001. Accordingly, the waiting
period under the HSR Act would then expire at 11:59 P.M., New York City time, on
or about August 3, 2001, which is the fifteenth 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 or the Company 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 or the Company prior to the expiration of
the fifteen day waiting period, the waiting period would be extended and would
expire at 11:59 P.M., New York City time, on the tenth calendar day after the
date of substantial compliance by Amerada Hess and the Company with such
request. If the acquisition of Ordinary Shares 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 Ordinary
Shares pursuant to the Offer will be deferred until ten 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). See Section 2 -- "Acceptance for
Payment and Payment for Ordinary Shares." 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. However, the closing
of the transaction may be extended or delayed by court order or by agreement of
the parties in order to give the FTC or the Antitrust Division the opportunity
to further evaluate the transaction. Although the Company is required to file
certain information and documentary material with the Antitrust Division and the
FTC in connection with the Offer, neither the Company's failure to make such
filings nor a request to the Company 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. If any waiting period would expire on a
Saturday, Sunday or legal public holiday, then such period will be extended to
the next day that is not a Saturday, Sunday or legal public holiday.

     The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Ordinary
Shares by the Purchaser pursuant to the Offer. At any time before or after the
Purchaser's purchase of Ordinary Shares, 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,

                                        58
   62

including seeking to enjoin the acquisition of Ordinary Shares pursuant to the
Offer or seeking divestiture of Ordinary Shares acquired by the Purchaser or
divestiture of substantial assets of Amerada Hess, the Company 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 and the Purchaser believe that the
acquisition of Ordinary Shares by the Purchaser 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 Section 14 -- "Conditions of the Offer" for certain conditions to
the Offer, including conditions with respect to litigation and certain
governmental actions.

     16.  FEES AND EXPENSES.  Except as set forth below, neither Amerada Hess
nor the Purchaser will pay any fees or commissions to any broker, dealer or
other person for soliciting tenders of Ordinary Shares pursuant to the Offer.

     Amerada Hess and the Purchaser have engaged Goldman, Sachs & Co. as the
Dealer Managers in connection with the Offer and as financial advisors to
Amerada Hess in connection with its proposed acquisition of the Company.
Goldman, Sachs & Co. will receive reasonable and customary compensation for
their services as Dealer Managers and financial advisors, as the case may be,
will be reimbursed for certain reasonable out-of-pocket expenses and will be
indemnified against certain liabilities and expenses in connection therewith,
including certain liabilities under the United States federal securities laws.
Goldman, Sachs & Co. have rendered various investment banking and other advisory
services to Amerada Hess and its affiliates and are expected to render such
services in the future, for which they have received and they will continue to
receive customary compensation from Amerada Hess and its affiliates. In the
ordinary course of business, Goldman, Sachs & Co. and their affiliates may
actively trade or hold the securities of the Company for their own account or
for the account of customers, and, accordingly, may at any time hold a long or
short position in such securities.

     The Purchaser and Amerada Hess have also retained The Bank of New York as
the Depositary. The Depositary has not been retained to make solicitations or
recommendations in its role as Depositary. The Depositary will receive
reasonable and customary compensation for its services, will be reimbursed for
certain reasonable out-of-pocket expenses and will be indemnified against
certain liabilities and expenses in connection therewith, including certain
liabilities under the United States federal securities laws.

     In addition, the Purchaser and Amerada Hess have retained D.F. King & Co.,
Inc. to act as the Information Agent in connection with the Offer. The
Information Agent will receive reasonable and customary compensation for its
services, will be reimbursed for certain reasonable out-of-pocket expenses and
will be indemnified against certain liabilities and expenses in connection
therewith, including certain liabilities under the United States federal
securities laws.

     Brokers, dealers, commercial banks and trust companies will be reimbursed
by the Purchaser for customary mailing and handling expenses incurred by them in
forwarding offering material to their customers.

     17.  MISCELLANEOUS.  The Purchaser is not aware of any jurisdiction where
the making of the Offer is prohibited by any administrative or judicial action
pursuant to any valid state statute. If the Purchaser becomes aware of any valid
state statute prohibiting the making of the Offer or the acceptance of the
Ordinary Shares pursuant thereto, the Purchaser will make a good faith effort to
comply with such state statute or seek to have such statute declared
inapplicable to the Offer. If, after such good faith effort, the Purchaser
cannot comply with any such state statute, the Offer will not be made to (and
tenders will not be accepted from or on behalf of) Holders in such state. In any
jurisdiction where the securities, blue sky or other laws require the Offer to
be made by a licensed broker or dealer, the Offer shall be deemed to be made on
behalf of the Purchaser by the Dealer Managers or one or more registered brokers
or dealers which are licensed under the laws of such jurisdiction.

     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF AMERADA HESS OR THE PURCHASER NOT CONTAINED IN THIS
OFFER TO PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

     necessary to secure that the reconstruction or amalgamation is fully and
     effectively carried out.

or liabilities, that property shall, by virtue of the order, be transferred to
and vest in, and those liabilities shall, by virtue of the order, be transferred
to and become the liabilities of, the transferee company, and any such property

the compromise or arrangement, to cease to have effect.

which the order is made shall cause a copy thereof to be delivered to the
