                              ACQUISITION OF CITIC

                   PARTICIPATING INTEREST; OPTIONS TO CONVERT

ACQUISITION OF CITIC INTEREST

4.1   Subject to satisfaction of the Conditions Precedent and CITIC fulfilling
its obligations under Section 4.4, Pan-China will assign to CITIC at the Closing
a forty percent (40%) interest in the Contractor's Rights and Obligations (the
"CITIC INTEREST").

CONDITIONS PRECEDENT

4.2   Closing is subject to the satisfaction of the following conditions
precedent:

      (a)   CNPC giving its written consent to CITIC becoming a party to the
            Petroleum Contract;

      (b)   CNPC, Pan-China and CITIC executing an amending agreement to the
            Petroleum Contract to give effect to the amendments which CITIC
            considers necessary as a result of this Agreement and the Joint
            Operating Agreement;

      (c)   CNPC waiving its `right of first refusal' pursuant to Sections 23.2
            of the Petroleum Contract in relation to the acquisition by CITIC of
            the Participating Interest;

      (d)   All relevant PRC Governmental Authority approvals to this Agreement
            and the transactions contemplated in it being obtained;

      (e)   Completion of due diligence in respect of the Contract Area and the
            Contractor's Rights and Interests to the satisfaction of CITIC;

      (f)   CITIC and Pan-China entering into the Joint Operating Agreement and
            an agreement concerning any financial or other assistance to be
            provided by CITIC to Pan-China; and

      (g)   CITIC being satisfied that on the basis of such approvals or
            agreements as it may request including in relation to the Ivanhoe
            Shares an approval from Toronto Stock Exchange and on currently
            applicable rules, an exercise of the options under Section 4.6 will
            be possible without undue delay or expense to CITIC.

SATISFACTION OF CONDITIONS PRECEDENT

4.3   Each Party will:

      (a)   use all reasonable endeavours to achieve early satisfaction of the
            Conditions Precedent;

      (b)   do all things and execute all documents as are reasonably necessary
            to achieve the satisfaction of the Conditions Precedent as soon as
            practicable; and

                                                                         Page 10
<PAGE>

      (c)   keep each other informed regarding progress and their reasonable
            endeavours to satisfy the Conditions Precedent on a regular basis
            and will notify one another in writing when any Condition Precedent
            has been satisfied.

Either Party may terminate this Agreement by giving notice to the other Party
and the Companies if the Conditions Precedent have not been satisfied or waived
by March 15, 2004, or such later date as the Parties may agree in writing. If
this Agreement is terminated pursuant to this Section 4.3, the Parties and the
Companies shall be freed and discharged from all further obligations and
liabilities under this Agreement but without prejudice to any rights, remedies,
powers, obligations and liabilities in respect of this Agreement accrued at or
prior to the receipt of the notice of termination given pursuant to this Section
or to any continuing obligations under Section 6.

CONSIDERATION FOR CITIC INTEREST

4.4   In consideration for the CITIC Interest and following satisfaction of the
Conditions Precedent, CITIC will pay to Pan-China at Closing the sum of Twenty
Million Dollars ($20,000,000) without any deduction, withholding or setoff
whatsoever (the "PAYMENT"). The Payment will be used exclusively by Pan-China
for Development Costs for the initial development phase of the Overall
Development Program under the Kongnan Contract, including but not limited to
drilling, completing and producing new wells, producing existing wells,
installation of surface facilities and development of the water injection scheme
for the Kongnan Project.

PAYMENT IS A DEVELOPMENT COST

For the avoidance of doubt, the Payment constitutes a Development Cost for the
purposes of the Petroleum Contract and CITIC is entitled to its Participating
Interest share of investment recovery oil in respect of the Payment.

OPTIONS TO CONVERT PARTICIPATING INTEREST

4.6   CITIC may, subject to all applicable stock exchange approvals, elect by
notice to Sunwing and Pan-China to convert its Participating Interest into
Sunwing common shares at any time ("SUNWING OPTION PERIOD") prior to the first
anniversary of the date that Sunwing completes an initial public offering
("IPO"). The number of Sunwing common shares ("SUNWING SHARES") issuable to
CITIC upon conversion of its Participating Interest will be determined by
dividing the Payment (less any net cash flow received by CITIC on account of its
Participating Interest prior to conversion) by the "SUNWING CONVERSION PRICE".
If CITIC elects to convert at least 10 days prior to the completion date of
Sunwing's IPO, the Sunwing Conversion Price will be the IPO price per common
share, less a 10% discount. If CITIC elects to convert thereafter and within one
year after Sunwing's IPO, the Sunwing Conversion Price will be a price per share
equal to the volume weighted average trading price of Sunwing's common shares on
the principal stock exchange on which such shares are traded, for the 30 trading
days immediately preceding CITIC's conversion election, less an 8% discount. If
CITIC elects to convert its Participating Interest, Sunwing must allot and issue
the Sunwing Shares to CITIC within fourteen (14) days after CITIC has given
notice to Pan-China and Sunwing pursuant to this section and promptly deliver to
CITIC certificates issued by Sunwing in respect of the Sunwing Shares.

Instead of electing to convert into Sunwing Shares, CITIC may, subject to all
applicable stock exchange approvals, elect by notice to Pan-China and Ivanhoe to
convert its Participating

                                                                         Page 11
<PAGE>

Interest into Ivanhoe common shares at any time prior to eighteen months after
the Closing ("IVANHOE OPTION PERIOD") of CITIC's acquisition of its
Participating Interest. The number of Ivanhoe common shares ("IVANHOE SHARES")
issuable upon conversion of its Participating Interest will be determined by
dividing the Payment (less any net cash flow received by CITIC on account of its
Participating Interest prior to conversion) by the "IVANHOE CONVERSION PRICE".
The Ivanhoe Conversion Price will be a price per common share equal to the
volume weighted average trading price of Ivanhoe's common shares on the Toronto
Stock Exchange, for the 30 trading days preceding CITIC's conversion election,
less an 8% discount. If CITIC elects to convert its Participating Interest,
Ivanhoe must allot and issue the required number of Ivanhoe common shares to
CITIC within fourteen (14) days after CITIC has given notice to Pan-China and
Ivanhoe pursuant to this section and promptly deliver to CITIC certificates
issued by Ivanhoe in respect of the Ivanhoe Shares.

If the Sunwing Conversion Price or Ivanhoe Conversion Price when calculated in
the manner described above is not an amount in Dollars then it shall be
converted into Dollars by reference to the average (mean) exchange rate (middle
price) quoted by the Bank of China for the currency in which the Sunwing
Conversion Price or Ivanhoe Conversion Price (as the case may be) is calculated
and Dollars for the 30 day period preceeding CITIC's conversion election. Any
partial number of relevant common shares shall be rounded up to the next whole
number.

REASSIGNMENT OF CITIC'S INTEREST

4.7   On conversion of its interest pursuant to Section 4.6, the CITIC Interest
automatically is assigned to Pan-China and CITIC agrees to provide all
reasonable assistance to Pan-China to give effect to this reassignment. The
provisions of Part 10 and Part 11 of the Joint Operating Agreement do not apply
to a reassignment of CITIC's Interest pursuant to this Section 4.7.

NO LIABILITY AFTER REASSIGNMENT

4.8   On reassignment of CITIC's Participating Interest to Pan-China pursuant to
Section 4.7 ("REASSIGNMENT DATE"), CITIC has no further obligation and has no
liability in respect of the Participating Interest other than in respect of
obligations or liabilities that accrued or were incurred prior to the
Reassignment Date.

UNDERTAKINGS BY SUNWING AND IVANHOE

4.9   Each of Sunwing and Ivanhoe respectively undertakes to CITIC that from the
date of this Agreement to the end of the Sunwing Option Period or the Ivanhoe
Option Period (as applicable), except to the extent CITIC otherwise consents:

      (a)   (CORPORATE EXISTENCE) it will do all things necessary to maintain

            account and annual report; and

                                                                         Page 12
<PAGE>

      (d)   (LITIGATION) it will give notice to CITIC as soon as it becomes
            aware of all litigation, arbitration or similar proceedings to which
            it is a party involving a claim in excess of $5 million or its
            equivalent other than a claim which is fully insured against, unless
            the insurer has indicated it intends to deny liability.

WARRANTIES BY SUNWING AND IVANHOE

4.10   Each of Sunwing and Ivanhoe respectively warrants to CITIC that:

      (a)   (SECURITY INTERESTS) there will be, at the time CITIC exercises its
            option pursuant to Section 4.6, no Encumbrance on or over or
            affecting the Sunwing Shares or the Ivanhoe Shares (as applicable)
            and there is no agreement or arrangement to give or create any such
            Encumbrance;

      (b)   (CONSENT) it will be, at the time CITIC exercises its option
            pursuant to Section 4.6, entitled to allot the Sunwing Shares or the
            Ivanhoe Shares (as applicable) without the consent of any third
            parties; and

      (c)   (TITLE) on allotment and issue of the shares CITIC shall receive
            valid and marketable title to the Sunwing Shares or the Ivanhoe
            Shares (as applicable).

AREA OF INTEREST

2.6   If, at any time during the term of this Agreement, a Party acquires an
interest or the right to acquire an interest of any nature whatsoever within the
Area of Interest which entitles or, if acquired, would entitle, the Party to
explore for, develop or produce Petroleum (an "OPPORTUNITY"), the Party will,
within fifteen (15) days of acquiring the Opportunity, notify the other Parties
with full particulars thereof. Within thirty (30) days of receiving the Party's
notice, each of the other Parties will notify the acquiring Party of its
election to accept or not accept the Opportunity and failure to respond will be
deemed to be an election to not accept the Opportunity. If all the other Parties
elect to accept the Opportunity, the non-acquiring Parties will reimburse the
acquiring Party for its out of pocket costs of acquiring the Opportunity and all
of the Parties will be entitled to participate therein in proportion to their
respective Participating Interests and, subject always to the legal and
contractual terms of the Opportunity, the Parties will, in good faith, negotiate
a definitive participation agreement which will, unless otherwise agreed,
contemplate joint participation in the Opportunity, and the rights and
obligations comprised therein, by the Parties in accordance with their

LIABILITY OF OPERATOR

3.6   Except as set out in this Section 3.6, the Party designated as Operator
shall bear no cost, expense or liability resulting from performing the duties

behalf of any person or entity for damage to or loss of property or the
environment, or for injury to, illness or death of any person or entity, which
damage, loss, injury, illness or death arises out of or is incident to any act
or failure to act by Indemnitees in the conduct of or in connection with
Petroleum Operations regardless of the cause of such damage, loss, injury,
illness or death and even though caused in whole or in part by a pre-existing
defect, the negligence (whether sole, joint or concurrent) Gross Negligence,
strict liability or other legal fault of Operator (or any such affiliate);
provided that if any senior supervisory personnel of Operator, engage in Gross
Negligence or wilful misconduct that proximately causes the Parties to incur
cost, expense or liability for such damage, loss, injury, illness or death, then
only Operator shall bear the actual cost, expense and liability to repair,
replace and/or remove property so damaged or lost, if any. Notwithstanding the
foregoing, under no circumstances shall any Indemnitee (except as a Party to the
extent of its Participating Interest) bear any cost, expense or liability for
environmental, consequential, punitive or any other similar indirect damages or
losses, including but not limited to those arising from business interruption,
reservoir or formation damage, inability to produce petroleum, loss of profits,
pollution control and environmental amelioration or rehabilitation.

INSURANCE OBTAINED BY OPERATOR

3.7   Operator shall procure and maintain or cause to be procured and maintained
all insurance in the types and amounts required by the Petroleum Contract and

time to time require. In respect of all insurance obtained pursuant to this
Section 3.7, the Operator shall:

      (a)   promptly inform the Parties when such insurance is obtained and
            supply them with copies of the relevant policies when the same are
            issued;

                                                                         Page 17
<PAGE>

      (b)   subject to the Petroleum Contract, arrange for the Parties,
            according to their respective Participating Interests, to be named
            as co-insureds on the relevant policies with waivers of subrogation
            in favour of all the Parties; and

      (c)   subject to the Petroleum Contract, duly file all claims and take all
            necessary and proper steps to collect any proceeds and credit any
            proceeds to the Parties in proportion to their respective
            Participating Interests.

Operator shall use its reasonable efforts to require all contractors performing
work in respect of Petroleum Operations to obtain and maintain any and all
insurance in the types and amounts required by any applicable laws, rules and
regulations or any decision of the Operating Committee and shall use its
reasonable efforts to require all such contractors to name the Parties as
additional insureds on contractors' insurance policies or to obtain from their
insurers waivers of all rights or recourse against Operator and the Parties.

COMMINGLING OF FUNDS

3.8   Operator may not commingle with its own funds the monies, which it
receives from or for the Joint Account pursuant to this Agreement. Monies
received from or for the Joint Account shall be applied only to their intended
use and shall in no way be deemed to be funds belonging to Operator.

3.9   The Operator may not resign as Operator except in accordance with the
Petroleum Contract and subject to receiving prior consent from CITIC.

DEFAULT BY OPERATOR UNDER PETROLEUM CONTRACT

3.10  A default by the Operator under the Petroleum contract is deemed to be a

            Contractor's Obligations, has been properly proposed to the
            Operating Committee and the Operating Committee has not approved
            such proposal in a timely manner, then any Party shall have the
            right for the appropriate period specified below to propose in

                                                                         Page 21
<PAGE>

            accordance with Part 5, an Exclusive Operation involving operations
            essentially the same as those proposed for such Joint Operation as
            follows,

            (i)   for proposals involving the use of a drilling rig that is
                  standing by in the Contract Area, such right shall be
                  exercisable for twenty-four (24) hours after the time
                  specified in Section 4.12(a) has expired;

            (ii)  for proposals to develop a Discovery, such right shall be
                  exercisable for twenty (20) days after the date the Operating
                  Committee considered such proposal pursuant to Section 4.6 or
                  Section 4.12; and

            (iii) for all other proposals, such right shall be exercisable for
                  twenty (20) days after the date the Operating Committee
                  considered such proposal pursuant to Section 4.6 or Section
                  4.12;

      (b)   if a Party voted against any proposal which was approved by the
            Operating Committee and which could be conducted as an Exclusive
            Operation pursuant to Part 5 other than any proposal relating to the
            fulfilment of Contractor's Obligations, then such Party shall have
            the right not to participate in the operation contemplated by such
            approval. Any such Party wishing to exercise its right of
            non-consent must give notice of non-consent to all other Parties
            within ten (10) days (or within twenty-four (24) hours if the
            drilling rig to be used in such operation is standing by in the
            Contract Area) following Operating Committee approval of such
            proposal. The Parties that did not give notice of non-consent shall
            be Consenting Parties as to the operation contemplated by the
            Operating Committee approval, and shall conduct such operation as an
            Exclusive Operation under Part 5. Any Party that gave notice of
            non-consent shall be a Non-Consenting Party as to such Exclusive
            Operation;

      (c)   if the Consenting Parties to an Exclusive Operation under
            subparagraphs (a) or (b) above concur, then the Operating Committee
            may, at any time, pursuant to subparagraph (c), reconsider and
            approve, decide or take action on any proposal that the Operating
            Committee declined to approve earlier, or modify or revoke an
            earlier approval, decision or action; and

      (d)   once a Joint Operation for the drilling, Deepening, Testing,
            Sidetracking, Plugging Back, Completing, Recompleting, Reworking or
            plugging of a well, has been approved and commenced, such operation
            shall not be discontinued without the consent of the Operating
            Committee provided, however, that such operation may be
            discontinued, if,

            (i)   an impenetrable substance or other condition in the hole is
                  encountered which, in the reasonable judgement of Operator,
                  causes the continuation of such operation to be impractical;
                  or

            (ii)  other circumstances occur which, in the reasonable judgement
                  of Operator, causes the continuation of such operation to be
                  unwarranted and, after notice, the Operating Committee, within
                  the period required under Section 4.12(a), approves
                  discontinuing such operation.

                                                                         Page 22
<PAGE>

            On the occurrence of either of the above, Operator shall promptly
            notify the Parties that such operation is being discontinued
            pursuant to the foregoing, and any Party shall have the right to
            propose in accordance with Part 5 an Exclusive Operation to continue
            such operation.

                                     PART 5

                       OPERATIONS BY LESS THAN ALL PARTIES

LIMITATION ON APPLICABILITY

5.1   No operations may be conducted in furtherance of the Petroleum Contract
except as Petroleum Operations in which the Parties participate in the
Contractor's Rights and Obligations to the extent of their respective
Participating Interests ("JOINT OPERATIONS"), or as Exclusive Operations under
this Part. No Exclusive Operation shall be conducted which conflicts with a
Joint Operation. Petroleum Operations which are required to fulfil the
Contractor's Obligations must be proposed and conducted as Joint Operations
under Part 4, and may not be proposed or conducted as Exclusive Operations under
this Part. In addition, no Party may propose or conduct an Exclusive Operation
under this Part unless and until such Party has properly exercised its right to
propose an Exclusive Operation pursuant to Section 4.13. Subject to this Part,
any operation that may be proposed and conducted as a Joint Operation, other
than operations pursuant to an approved Overall Development Program, may be
proposed and conducted as an Exclusive Operation.

PROCEDURE TO PROPOSE EXCLUSIVE OPERATIONS

5.2   Subject to Section 5.1, if any Party proposes to conduct an Exclusive
Operation, such Party shall give notice of the proposed operation to all
Parties. Such notice shall specify that such operation is proposed as an
Exclusive Operation, the work to be performed, the location, the objectives, and
estimated cost of such operation. Any Party entitled to receive such notice
shall have the right to participate in the proposed operation by notifying the
Operator or the Party proposing the Exclusive Operation as follows:

      (a)   for proposals to Deepen, Test, Complete, Sidetrack, Plug Back,
            Recomplete or Rework involving the use of a drilling rig that is
            standing by in the Contract Area, any such Party wishing to exercise
            such right must so notify Operator within twenty-four (24) hours
            after receipt of the notice proposing the Exclusive Operation;

      (b)   for proposals to develop a Discovery, any Party wishing to exercise
            such right must so notify the proposing Party within twenty (20)
            days after receipt of the notice proposing the Exclusive Operation;
            and

      (c)   for all other proposals, any such Party wishing to exercise such
            right must so notify Operator within ten (10) days after receipt of
            the notice proposing the Exclusive Operation.

Failure of a Party to whom a proposal notice is delivered to properly reply
within the period specified above shall constitute an election by that Party not
to participate in the proposed operation. If all Parties properly exercise their
rights to participate, then the proposed

                                                                         Page 23
<PAGE>

operation shall be conducted as a Joint Operation. The Operator shall commence
such Joint Operation as promptly as practicable and conduct it with due
diligence. If less than all Parties entitled to receive such proposal notice
properly exercise their rights to participate, then:

      (d)   the Party proposing the Exclusive Operation, together with any other
            Parties who elect to participate (collectively "CONSENTING PARTIES")
            shall have the right to instruct Operator (subject to Section
            5.8(e)) to conduct the Exclusive Operation;

      (e)   if the Exclusive Operation is conducted, the Consenting Parties
            shall bear the sole liability and expense of such Exclusive
            Operation in a fraction, the numerator of which is such Consenting
            Party's Participating Interest and the denominator of which is the
            aggregate of the Participating Interests of the Consenting Parties
            or in such other proportion totalling one hundred per cent (100%) of
            such liability and expense as the Consenting Parties may agree; and

      (f)   if such Exclusive Operation has not been commenced within one
            hundred and eighty (180) days (excluding any extension specifically
            agreed by all Consenting Parties or allowed by the force majeure
            provisions of Part 14), the right to conduct such Exclusive
            Operation shall terminate. If any Party still desires to conduct
            such Exclusive Operation, written notice proposing such operation
            must be resubmitted to the Parties in accordance with Part 4 as if
            no proposal to conduct an Exclusive Operation had been previously
            made.

      Notwithstanding the foregoing, no Exclusive Operation may be undertaken if
      it would interfere with a previously approved and ongoing Joint Operation.

RESPONSIBILITY FOR EXCLUSIVE OPERATIONS

5.3   The Consenting Parties shall bear in accordance with the Participating
Interests agreed under Section 5.2(e) the entire cost and liability of
conducting an Exclusive Operation to the exclusion of any Party who does not
elect to participate (a "NON-CONSENTING PARTY") and shall indemnify the
Non-Consenting Parties from any and all costs and liabilities incurred incident
to such Exclusive Operation and shall keep the Contract Area free and clear of
all Encumbrances of every kind created by or arising from such Exclusive
Operation.

CONSEQUENCES OF EXCLUSIVE OPERATIONS

5.4   With regard to any Exclusive Operation:


      (a)   for so long as a Non-Consenting Party has the option to reinstate
            the rights it relinquished as established in Section 5.4(b), such
            Non-Consenting Party shall be entitled to have access concurrently
            with the Consenting Parties, to all data and other information
            relating to such Exclusive Operation, other than G & G Data obtained
            in an Exclusive Operation. If a Non-Consenting Party desires to
            receive and acquire the right to use such G & G Data, then such
            Non-Consenting Party shall have the right to do so by paying to the
            Consenting Parties its Participating Interest share of the cost
            incurred in obtaining such G & G Data;

                                                                         Page 24
<PAGE>

      (b)   subject to this Section 5.4, each Non-Consenting Party shall be
            deemed to have relinquished to the Consenting Parties, and the
            Consenting Parties shall be deemed to own, in proportion to their
            respective Participating Interests in the Exclusive Operation:

            (i)   all of each such Non-Consenting Party's right to participate
                  in further operations on any Discovery made in the course of
                  such Exclusive Operation; and

            (ii)  all of each such Non-Consenting Party's right pursuant to the
                  Petroleum Contract to take and dispose of Petroleum produced
                  and saved or to receive its Participating Interest Share of
                  Net Operating Cash Flow:

                  (A)   from the well in which such Exclusive Operation was
                        conducted, and

                  (B)   from any wells drilled to appraise or develop a
                        Discovery;

      (c)   a Non-Consenting Party shall have the following and only the
            following options to reinstate the rights it relinquished pursuant
            to this Section 5.4:

            (i)   if the Consenting Parties decide to appraise a Discovery made
                  in the course of an Exclusive Operation, the Consenting
                  Parties shall submit to each Non-Consenting Party the approved
                  appraisal program. For thirty (30) days (or forty-eight (48)
                  hours if the drilling rig which is to be used in such
                  appraisal program is standing by in the Contract Area) from
                  receipt of such appraisal program, each Non-Consenting Party
                  shall have the option to reinstate the rights it relinquished
                  pursuant to subparagraph (b) above and to participate in such
                  appraisal program. The Non-Consenting Party may exercise such
                  option by notifying Operator within the period specified above
                  that such Non-Consenting Party agrees to bear its
                  Participating Interest share of the expense and liability of
                  such appraisal program, to pay the lump sum amount as set out
                  in Section 5.5(a) and to pay the cash premium as set out in
                  Section 5.5(b);

            (ii)  if the Consenting Parties decide to develop a Discovery made
                  or appraised in the course of an Exclusive Operation, the
                  Consenting Parties shall submit to the Non-Consenting Parties
                  a development plan substantially in the form intended to be
                  submitted to CNPC and the relevant Governmental Authorities in
                  the PRC under the Petroleum Contract. For sixty (60) days from
                  receipt of such development plan or such lesser period of time
                  prescribed by the Petroleum Contract, each Non-Consenting
                  Party shall have the option to reinstate the rights it
                  relinquished pursuant to subparagraph (b) above and to
                  participate in such development plan. The Non-Consenting Party
                  may exercise such option by notifying the Operator within the
                  period specified above that such Non-Consenting Party agrees
                  to bear its Participating Interest share of the liability and
                  expense of such development plan and such future operating and
                  producing costs, to pay the lump sum amount as set out in
                  Section 5.5(a) and to pay the cash premium as set out in
                  Section 5.5(b); and

                                                                         Page 25
<PAGE>

            (iii) if the Consenting Parties decide to Deepen, Test, Complete,
                  Sidetrack, Plug Back, Recomplete or Rework an Exclusive Well
                  and such further operation was not included in the original
                  proposal for such Exclusive Well, the Consenting Parties shall
                  submit to the Non-Consenting Parties an authorisation for
                  expenditure outlining the Consenting Parties' best estimate of
                  the total funds required to carry out such further operation.
                  For thirty (30) days (or forty-eight (48) hours if the
                  drilling rig which is to be used in such operation is standing
                  by in the Contract Area) from receipt of such authorisation
                  for expenditure, each Non-Consenting Party shall have the
                  option to reinstate the rights it relinquished pursuant to
                  subparagraph (b) above and to participate in such operation.
                  The Non-Consenting Party may exercise such option by notifying
                  the Operator within the period specified above that such
                  Non-Consenting Party agrees to bear its Participating Interest
                  share of the liability and expense of such further operation,
                  to pay the lump sum amount as set out in Section 5.5(a) and to
                  pay the cash premium as set out in Section 5.5(b);

      (d)   if a Non-Consenting Party does not properly and in a timely manner
            exercise such option, including paying in a timely manner in
            accordance with Section 5.5, all lump sum amounts and cash premiums,
            if any, due to the Consenting Parties, such Non-Consenting Party
            shall have forfeited the options as set out in subparagraph (c)
            above and the right to participate in the proposed program, unless
            such program, plan or operation is materially modified or expanded;

      (e)   a Non-Consenting Party shall become a Consenting Party with regard
            to an Exclusive Operation at such time as the Non-Consenting Party
            gives proper notice pursuant to subparagraph (c) above provided that
            such Non-Consenting Party shall in no way be deemed to be entitled
            to any lump sum amount or cash premium paid as an incident to such
            Exclusive Operation. The Participating Interest of such
            Non-Consenting Party in such Exclusive Operation shall be its
            Participating Interest in the Contractor's Rights and Obligations.
            The Consenting Parties shall contribute in proportion to their
            respective Participating Interests in such Exclusive Operation, the
            Participating Interest of any Non-Consenting Party. If all Parties
            participate in the proposed operation, then such operation shall be
            conducted as a Joint Operation pursuant to Part 4; and


      (f)   if, after the expiry of the period in which a Non-Consenting Party
            may exercise its option to participate in a development plan, the
            Consenting Parties desire to proceed, each Non-Consenting Party to
            such development plan shall be deemed to have:


            (i)   forfeited all of its economic interest in that part of the
                  Contract Area or any other area covered by such development
                  plan, and

            (ii)  assumed a fiduciary duty to exercise its legal interest in the
                  Petroleum Contract to the extent it relates to any areas
                  covered by the development plan for the benefit of the
                  Consenting Parties.

      In either case such Non-Consenting Party shall be deemed to have withdrawn
      from this Agreement to the extent it relates to such area, even if the
      development plan is modified

                                                                         Page 26

      or expanded subsequent to the commencement of operations under such
      development plan.

            such Non-Consenting Party; and

      (b)   in addition to Section 5.5(a), each such Non-Consenting Party shall

                  Reworking of the exploration well which made the Discovery in
                  which the Non-Consenting Party desires to reinstate the rights
                  it relinquished pursuant to Section 5.4(b), and that were not

ORDER OF PREFERENCE OF OPERATIONS

5.6   Except as otherwise specifically provided in this Agreement, if any Party
desires to propose the conduct of an operation that will conflict with an
existing proposal for an Exclusive Operation, such Party shall have the right
exercisable for five (5) days, or twenty-four (24) hours if the drilling rig to
be used is standing by in the Contract Area, from receipt of the proposal for
the Exclusive Operation, to deliver to all Parties entitled to participate in
the proposed operation such Party's alternative proposal. Such alternative
proposal shall contain the information required under Section 5.2. Each Party
receiving such proposals shall elect by delivery of notice to Operator within
the appropriate response period set out in Sections 5.2(a) through (c) to
participate in one of the competing proposals. Any Party not notifying Operator
within the response period shall be deemed not to have voted. The proposal
receiving the largest aggregate Participating Interest vote shall have priority
over all other competing proposals. In the case of a tie vote, the Operator
shall choose among the proposals receiving the largest aggregate Participating
Interest vote. Operator shall deliver notice of such result to all Parties
entitled to participate in the operation within five (5) days of the end of the
response period, or twenty-four (24) hours if the drilling rig to be used is
standing by in the Contract Area. Each Party shall then have two (2) days (or
twenty-four (24) hours if the drilling rig to be used is standing by in the
Contract Area) from receipt of such notice to elect by delivery of notice to
Operator whether such Party will participate in such Exclusive Operation, or
will relinquish its interest pursuant to Section 5.4(b). Failure by a Party to
deliver such notice within such period shall be deemed an election not to
participate in the prevailing proposal.

STAND-BY COSTS

5.7   When an operation has been performed, all tests have been conducted and
the results of such tests furnished to the Parties, stand by costs incurred
pending response to any Party's notice proposing an Exclusive Operation for
Deepening, Testing, Sidetracking, Completing, Plugging Back, Recompleting,
Reworking or other further operation in such well (including the period required
under Section 5.6 to resolve competing proposals) shall be charged and borne as
part of the operation just completed. Stand by costs incurred subsequent to all
Parties responding, or expiration of the response time permitted, whichever
first occurs, shall be charged to and borne by the Parties proposing the
Exclusive Operation in proportion to their Participating Interests, regardless
of whether such Exclusive Operation is actually conducted. If a further
operation is proposed while the drilling rig to be utilised is on location, any
Party may request and receive up to five (5) additional days after expiration of
the applicable response period specified in Sections 5.2(a) through (c) within
which to respond by notifying Operator that such Party agrees to bear all stand
by costs and other costs incurred during such extended response period. Operator
may require such Party to pay the estimated stand by time in advance as a
condition to extending the response period. If more than one Party requests such
additional time to respond to the notice, stand by costs shall be allocated
between such Parties on a day-to-day basis in proportion to their Participating
Interests.

MISCELLANEOUS

5.8   Under this Part:

      (a)   each Exclusive Operation shall be carried out by the Consenting
            Parties acting as the Operating Committee, subject to the provisions
            of this Agreement applied

                                                                         Page 28
<PAGE>

            mutatis mutandis to such Exclusive Operation and subject to the
            terms and conditions of the Petroleum Contract;

      (b)   the computation of liabilities and expenses incurred in Exclusive
            Operations, including the liabilities and expenses of Operator for
            conducting such operations, shall be made in accordance with the
            principles set out in the Accounting Procedure;

      (c)   Operator shall maintain separate books, financial records and
            accounts for Exclusive Operations which shall be subject to the same
            rights of audit and examination as provided in the Accounting
            Procedure. Such rights of audit and examination shall extend to each
            of the Consenting Parties and each of the Non-Consenting Parties so
            long as the latter are, or may be, entitled to elect to participate
            in such operations;

      (d)   Operator, if it is a Non-Consenting Party and it is conducting an
            Exclusive Operation for the Consenting Parties, shall be entitled to
            request cash advances and shall not be required to use its own funds
            to pay any cost and expense and shall not be obliged to commence or
            continue Exclusive Operations until cash advances requested have
            been made, and the Accounting Procedure shall apply to Operator in
            respect of any Exclusive Operations conducted by it; and

      (e)   if the Operator is a Non-Consenting Party to an Exclusive Operation
            to develop a Discovery then, subject to obtaining any necessary
            CNPC/PRC Approval, the Operator may resign but, in any event, shall
            resign, on the request of the Consenting Parties, as Operator for
            that portion of the Contract Area comprising such Discovery and,
            subject to the terms of the Petroleum Contract, the Consenting
            Parties shall select another Party to serve as Operator.

                                     PART 6

                                  WORK PROGRAMS

REVIEW AND APPROVAL

6.1   At least sixty (60) days prior to the date upon which the Operator is
obliged, under the Petroleum Contract, to submit to the JMC an annual Work
Program and Budget for the JMC's review and approval, the Operator will furnish
a draft of such Work Program and Budget to the Parties. Within thirty (30) days
of such delivery, the Operating Committee will meet to consider and approve the
draft Work Program and Budget with such modifications as the Operating Committee
determines are warranted and, immediately following such approval, the Operator
will submit the approved Work Program and Budget to the JMC for consideration in
accordance with the terms of the Petroleum Contract. If further modifications to
a Work Program and Budget approved by the Operating Committee are required prior
to approval thereof by the JMC, the Contractor's representatives on the JMC may
approve any such modifications on behalf of the Parties without further
consideration or approval by the Operating Committee.

                                                                         Page 29
<PAGE>

      (a)   During the preparation of the proposed Work Programs and Budgets and
            Development Plans contemplated in this Part 6, Operator shall
            consult with the Operating Committee or the appropriate
            subcommittees regarding the contents of such Work Programs and
            Budgets and Development Plans;

      (b)   Each Work Program and Budget and Overall Development Plan submitted
            by Operator shall contain an itemised estimate of the costs of Joint
            Operations and all other expenditures to be made for the Joint
            Account for the period covered by the Work Program and shall, inter
            alia

            (i)   identify each work category in sufficient detail to afford the
                  ready identification of the nature, scope and duration of the
                  activity in question;

            (ii)  include such reasonable information regarding Operator's
                  allocation procedures and estimated manpower costs as the
                  Operating Committee may determine;

            (iii) comply with the requirements of the Petroleum Contract;

      (c)   The Work Program and Budget shall designate the portion or portions
            of the Contract Area in which Joint Operations itemised in such Work
            Program and Budget are to be conducted and shall specify the kind
            and extent of such operations in such detail as the Operating
            Committee may deem suitable.

AUTHORISATION FOR EXPENDITURE ("AFE") PROCEDURE

6.2   Prior to incurring any commitment or expenditure for the Joint Account,
which is estimated to be in excess of One Hundred Fifty Thousand Dollars
($150,000.00) for any line item in an approved Work Program and Budget, Operator
shall send to each Party an AFE containing Operator's best estimate of the total
funds required to carry out such work, the estimated timing of expenditures and
any other necessary supporting information. The Parties shall sign the AFE
acknowledging their receipt of the AFE.

      (a)   Approval of an operation in the current Work Program and Budget
            shall authorise Operator to conduct the operation subject to Section
            6.3 of this Agreement without further authorisation from the
            Operating Committee.

      (b)   Each AFE proposed by the Operator shall:

            (i)   Identify the operation by specific reference to the applicable
                  line items in the Work Program and Budget;

            (ii)  Describe the work in detail;

            (iii) Contain Operator's best estimate of the total funds required
                  to carry out such work;

            (iv)  Outline the proposed work schedule;

            (v)   Provide a timetable of expenditures, if known; and

                                                                         Page 30
<PAGE>

            (vi)  Be accompanied by such other supporting information as is
                  necessary for an informed decision.

OVEREXPENDITURES OF WORK PROGRAMS AND BUDGETS

6.3   (a)   For expenditures on any line item of an approved Work Program
            and and Budget, Operator shall be entitled to make or incur without
            further approval of the Operating Committee overexpenditures for
            such line item up to ten (10) percent of the authorised amount for
            such line item; provided that the cumulative total of all
            overexpenditures for a Calendar Year shall not exceed five (5)
            percent of the total Budget in question. Operator may also spend
            amounts in excess of an approved Budget in order to safeguard and
            prevent injury or death, or to prevent damage to property or
            pollution, and shall report the amounts spent for that purpose to
            the Parties.

      (b)   At such time that Operator is reasonably certain that the percentage
            overexpenditure limits of Section 6.3(A) will be exceeded, Operator
            shall furnish a supplemental AFE for the estimated overexpenditures
            to the Operating Committee for its approval and shall provide the
            Parties with full details of such overexpenditures. Operator shall
            promptly give notice of the amounts of overexpenditures when
            actually incurred.

DEVELOPMENT

6.4   (a)   If the Operating Committee determines that a Discovery may be
            commercial, the Operator shall, as soon as practicable, deliver to
            the Parties a draft Overall Development Plan together with the first
            annual Work Program and Budget and provisional Work Programs and
            Budgets for the remainder of the development of the Discovery, which
            shall contain, inter alia:

            (i)   Details of the proposed work to be undertaken, personnel
                  required and expenditures to be incurred, including the timing
                  of same, on a Calendar Year basis;

            (ii)  An estimated date for the commencement of production;

            (iii) A delineation of the proposed Development Area; and


            (iv)  Any other information requested by the Operating Committee;

      (b)   After receipt of the draft Overall Development Plan, or earlier if
            necessary to meet any applicable deadline under the Petroleum
            Contract, the Operating Committee shall meet to consider, modify and
            then either approve or reject the draft Overall Development Plan and
            the first annual Work Program and Budget for the Development
            submitted by Operator. If the draft Overall Development Plan is
            approved by the Operating Committee, Operator shall, as soon as
            possible, deliver any notice of Commercial Discovery required under
            the Petroleum Contract and take such other steps as may be required
            under the Petroleum Contract to secure CNPC/PRC Approval. In the
            event CNPC or the Governmental Authority requires changes in the
            draft Overall Development

                                                                         Page 31
<PAGE>

            Plan, the matter shall be resubmitted to the Operating Committee for
            further consideration; and


      (c)   If the draft Overall Development Plan approved by the Operating
            Committee is also approved by CNPC and the applicable Governmental
            Authorities, it shall be incorporated into and form part of annual
            Work Programs and Budgets, and Operator shall, on or before the 1st
            day of August of each Calendar Year, submit a Work Program and
            Budget for the Production Area, for the following Calendar Year.
            Within forty-five (45) Days after such submittal, the Operating
            Committee shall endeavour to agree on such Work Program and budget,
            including any necessary or appropriate revisions to the Work Program
            and Budget for the approved Overall Development Plan.

                                     PART 7

                                     DEFAULT

DEFAULT AND NOTICE

7.1   Any Party that fails to pay when due its Participating Interest share of
Contractor's Expenses including cash advances and interest accrued pursuant to
this Agreement (a "DEFAULTING PARTY") shall be in default under this Agreement.
Operator, or any other Party in the case of the default of Operator, shall
promptly give written notice of such default to the Defaulting Party and each of
the non-defaulting Parties. The amount not paid by the Defaulting Party shall
bear interest from the date due until paid in full. Interest will be calculated
using LIBOR, plus five percent (5%), herein called the "AGREED INTEREST RATE".

OPERATING COMMITTEE MEETINGS

7.2   After any default has continued for ten (10) Business Days from the date
of written notice of default under Section 7.1, and for as long thereafter as
the Defaulting Party remains in default on any payment due under this Agreement,
the Defaulting Party shall not be entitled to attend Operating Committee
meetings or to vote on any matter coming before the Operating Committee during
the period such default continues. Unless agreed otherwise by the non-defaulting
Parties, the voting interest of each non-defaulting Party shall be in the
proportion which its Participating Interest bears to the total of the
Participating Interests of all the non-defaulting Parties. Any matters requiring
unanimous vote of the Parties shall be deemed to exclude the Defaulting Party.
After the said ten (10) Business Days and while the Defaulting Party remains in
default as aforesaid, the Defaulting Party shall not have access to any data or
information relating to Petroleum Operations.

ALLOCATION OF DEFAULTED ACCOUNTS

7.3   Operator shall, either at the time of giving notice of default as provided
in Section 7.1, or by separate notice, notify each non-defaulting Party of the
sum of money it is to pay as its portion (such portion being in the ratio that
each non-defaulting Party's Participating Interest bears to the Participating
Interests of all non-defaulting Parties) of such amount in default. Each
non-defaulting Party shall, if such default continues, pay Operator, within ten
(10) Business Days after receipt of such notice, its share of the amount, which
the Defaulting Party

                                                                         Page 32
<PAGE>

failed to pay. If any non-defaulting Party fails to pay its share of the amount
in default as aforesaid, such non-defaulting Party shall thereupon be in default
and shall be a Defaulting Party subject to the provisions of this Part. The
non-defaulting Parties which pay the amount owed by any Defaulting Party shall
be entitled to receive their respective share of the principal and interest
payable by such Defaulting Party pursuant to Section 7.1. The total of all
amounts paid by the non-defaulting Parties for the Defaulting Party, together
with interest at the Agreed Interest Rate accrued on such amounts shall
constitute a debt due and owing by the Defaulting Party to the non-defaulting
Parties in proportion to such amounts paid. In addition, the non-defaulting
Parties may in the manner contemplated by this Part, satisfy such debt (together
with interest at the Agreed Interest Rate) and may accrue an amount equal to the
Defaulting Party's Participating Interest share of the estimated cost to abandon
the Contractor's Rights and Interests. A Defaulting Party may remedy its default
by paying to Operator the total amount due, together with interest calculated at
the Agreed Interest Rate, at any time prior to transfer of its interest pursuant
to Section 7.4, and upon receipt of such payment Operator shall remit to each
non-defaulting Party its proportionate share of such amount. The rights granted
to each non-defaulting Party pursuant to this Part, shall be in addition to, and
not in substitution for any other rights or remedies which each non-defaulting
Party may have at law, in equity, pursuant to the provisions of the Petroleum
Contract or pursuant to the other provisions of this Agreement.

TRANSFER OF INTEREST

7.4   For a period of thirty (30) days after the failure by the Defaulting Party
to remedy its default by the thirtieth (30th) day following notice of default,
without prejudice to any other rights of the non-defaulting Parties to recover
the amounts paid for the Defaulting Party, together with interest accrued on
such amount, each non-defaulting Party shall have the option to give notice to
the Defaulting Party requiring the Defaulting Party to transfer its interest to
the non-defaulting Parties. To that end, if any of the non-defaulting Parties so
elect, the Defaulting Party shall be deemed to have transferred and to have
empowered the electing non-defaulting Parties to execute on said Defaulting
Party's behalf any documents required to effect a transfer, of all of its right,
title and beneficial interest in and under this Agreement and the Petroleum
Contract to the electing non-defaulting Parties. If requested, each Party shall
execute a power of attorney in the form prescribed by the Operating Committee.
The Defaulting Party shall, without delay following any request from the
non-defaulting Parties, do any and all acts required to be done by applicable
law or regulation in order to render such transfer legally valid, including,
without limitation, the obtaining of CNPC/PRC Approval, and shall execute any
and all documents and take such other actions as may be necessary in order to
effect prompt and valid transfer of the interests described above, free of all
Encumbrances. In the event all such approvals are not timely obtained, the
Defaulting Party shall hold its Participating Interest in trust for such
non-defaulting Parties who elected to assume such Defaulting Party's
Participating Interest. In the absence of an agreement among the non-defaulting
Parties to the contrary, any such transfer to the non-defaulting Parties shall
be in the proportion that the non-defaulting Parties have paid the amounts due
from the Defaulting Party. Subject to Section 10.1(c), on the effective date of
such transfer the Defaulting Party shall forthwith cease to be a Party to the
extent of the Participating Interest so transferred. The acceptance or
non-acceptance by a non-defaulting Party of any portion of a Defaulting Party's
Participating Interest shall be without prejudice to any rights or remedies such
non-defaulting Party have to recover the outstanding debts (including interest)
owed by the Defaulting Party.

                                                                         Page 33
<PAGE>

CONTINUATION OF INTEREST

7.5   If, during the thirty (30) days after the failure by the Defaulting Party
to remedy its default by the thirtieth (30th) day following notice of default,
the non-defaulting Parties elect to not acquire the Defaulting Party's
Participating Interest as provided in Section 7.4 and to continue to bear the
Defaulting Party's Participating Interest share of Contractor's Expenses, then
the non-defaulting Party shall accumulate all such liabilities and expenses as a
debt pursuant to Part 7, but the Defaulting Party shall continue to be a Party
subject to Section 7.2 and Section 7.7. If Operator disposes of any of the
Contractor's Rights and Interests for valuable consideration, or if Operator
sells any of the Defaulting Party's Participating Interest share of the
Contractor's allocation of Petroleum, then, in respect of the Defaulting Party's
Participating Interest share of the proceeds of such disposal, credit or
adjustment or sale, Operator shall be entitled to retain and to set off the same
against all amounts, together with interest accrued on such amount, due and
owing from the Defaulting Party plus an accrued amount equal to the Defaulting
Party's Participating Interest share of the estimated cost to abandon the
Contractor's Rights and Interests. Any surplus remaining after setting off the
same as aforesaid shall be paid promptly to the Defaulting Party.

ABANDONMENT

7.6   If, within the thirty (30) days after the failure by the Defaulting Party
to remedy its default by the thirtieth (30th) day as aforesaid, no
non-defaulting Party elects to acquire the Defaulting Party's Participating
Interest as provided in Section 7.4, or to bear the Defaulting Party's
Participating Interest share of Contractor's Expenses as provided in Section
7.5, then no transfer shall be made and the Contractor's Rights and Interests
shall be abandoned subject to any necessary consents and notices being given,
and each Party, including the Defaulting Party shall pay its Participating
Interest share of all costs of abandoning and relinquishing the Contractor's
Rights and Interests. If abandonment occurs as aforesaid, all monies paid by the
non-defaulting Parties for the Defaulting Party pursuant to Section 7.3,
together with interest accrued on such amount, shall remain a debt due and owing
by the Defaulting Party.

SALE OF PETROLEUM

7.7   If a Party defaults after the Date of Commencement of Commercial
Production and has not remedied the default by the thirtieth (30th) day as
aforesaid, then, during the continuance of such default, the Defaulting Party
shall not be entitled to its Participating Interest share of the Contractor's
allocation of Petroleum from Production Operations which shall vest in and be
the property of the non-defaulting Parties, and Operator shall be authorised to
sell such Petroleum at the best price obtainable under the circumstances and,
after deducting all costs, charges and expenses incurred by Operator in
connection with such sale, pay the proceeds proportionately to the
non-defaulting Parties which proceeds shall be credited against all monies
advanced pursuant to Section 7.3, together with interest accrued thereon. Any
surplus remaining shall be paid to the Defaulting Party, and any deficiency
shall remain a debt due from the Defaulting Party to the non-defaulting Parties.
Notwithstanding any such sales by Operator, the provisions of Section 7.4 shall
continue to apply.

NO RIGHT OF SET OFF

7.8   Each Party acknowledges and accepts that a fundamental principle of this
Agreement is that each Party pays its Participating Interest share of all
amounts including, without limitation, Contractor's Expenses due under this
Agreement as and when required.

                                                                         Page 34
<PAGE>

Accordingly, any Party which becomes a Defaulting Party undertakes that, in
respect of either any exercise by the non-defaulting Parties of any rights under
or the application of any of the provisions of this Part, such Party shall not
raise by way of set off or invoke as a defence, whether in law or equity, any
failure to pay amounts due and owing under this Agreement or any alleged or
unliquidated claim that such Party may have against Operator or any other Party,
whether such claim arises under this Agreement or otherwise. Such Party further
undertakes not to raise by way of defence, whether in law or in equity, that the
nature or the amount of the remedies granted to the non-defaulting Party is
unreasonable or excessive.

                            DISPOSITION OF PRODUCTION

RIGHT AND OBLIGATION TO TAKE IN KIND

8.1   Except as otherwise provided in the Petroleum Contract or this Agreement,
each Party shall have the right and obligation to own, take in kind and
separately dispose of its Participating Interest share of the Contractor's
allocation of Petroleum pursuant to the Petroleum Contract from the Production
Area in such quantities and in accordance with such procedures as may be set
forth in the offtake agreement referred to in Section 8.2 or the separate
agreement for Natural Gas referred to in Section 8.3.

OFFTAKE AGREEMENT FOR CRUDE OIL

8.2   The Parties shall in good faith, and not less than three (3) months prior
to first delivery of Crude Oil from the Production Area, negotiate and conclude
the terms of an agreement to cover the offtake of the Contractor's allocation of
Crude Oil under the Petroleum Contract. The terms of the offtake agreement will
be consistent with the provisions of the Petroleum Contract, and shall make
provision for:

      (a)   The delivery point, at which title and risk of loss of Participating
            Interest shares of crude oil shall pass to the Parties (or as the
            Parties may otherwise agree);

      (b)   The Operator's regular periodic advice to the Parties of estimates
            of total available production for succeeding periods, quantities of
            each grade of crude oil and each Party's share for as far ahead as
            is necessary for Operator and the Parties to plan offtake
            arrangements. Such advice shall also cover for each grade of crude
            oil total available production and deliveries for the preceding
            period, inventory and overlifts and underlifts;

      (c)   Nomination by the Parties to Operator of acceptance of their shares
            of total available production for the succeeding period. Such
            nominations shall in any one period be for each Party's entire share
            of available production during that period subject to operational
            tolerances and agreed minimum economic cargo sizes or as the Parties
            may otherwise agree;

      (d)   If offshore loading or a shore terminal for vessel loading is
            involved, risks regarding acceptability of tankers, demurrage and
            (if applicable) availability of berths;

                                                                         Page 35
<PAGE>

      (e)   Elimination of overlifts and underlifts;

      (f)   Distribution to the Parties of available grades, gravities and
            qualities of crude oil to ensure, to the extent Parties take
            delivery of their entitlements as they accrue, that each Party shall
            receive in each period entitlements of grades, gravities and
            qualities of crude oil from each Production Area in which it
            participates similar to the grades, gravities and qualities of crude
            oil received by each other Party from that Production Area in that
            period;

      (g)   To the extent that distribution of entitlements on such basis is
            impracticable due to availability of facilities and minimum cargo
            sizes, a method of making periodic adjustments; and

      (h)   The option and the right of the other Parties to sell an entitlement
            which a Party fails to nominate for acceptance pursuant to (c) above
            or of which a Party fails to take delivery, in accordance with
            applicable agreed procedures, provided that such failure either
            constitutes a breach of Operator's or Parties' obligations under the
            terms of the Petroleum Contract, or is likely to result in the
            curtailment or shut-in of production. Such sales shall be made only
            to the limited extent necessary to avoid disruption of Joint
            Operations. Operator shall give all Parties as much notice as is
            practicable of such unnominated or undelivered entitlement, as the
            case may be, and for reasonable periods of time as are consistent
            with the minimum needs of the industry and in no event to exceed
            three (3) months. The right of sale shall be revocable at will
            subject to any prior contractual commitments. Payment terms for
            production sold under this option shall be established in the
            offtake agreement. If an offtake agreement has not been entered into
            by the date of first delivery of crude oil, the Parties shall be
            bound by the principles set forth in this Section 8.2(h) until an
            offtake agreement has been entered into.

SEPARATE AGREEMENT FOR NATURAL GAS

8.3   The Parties recognise that if Natural Gas is discovered it may be
necessary for the Parties to enter into special arrangements for the disposal of
the Natural Gas, which are consistent with the Overall Development Program and
the terms of the Petroleum Contract.

                                     PART 9

                       SURRENDER, EXTENSIONS AND RENEWALS

SURRENDER

9.1   If the Petroleum Contract requires the Parties to surrender any portion of
the Contract Area, Operator shall advise the Operating Committee of such
requirement at least one hundred and twenty (120) days in advance of the earlier
of the date for filing irrevocable notice of such surrender or the date of such
surrender. Prior to the end of such period, the Operating Committee shall
determine pursuant to Part 4, the size and shape of the surrendered area,
consistent with the requirements of the Petroleum Contract. If a unanimous vote
of the Operating Committee cannot be attained, then the proposal supported by a
simple majority of

                                                                         Page 36
<PAGE>

the Participating Interests shall be adopted. If no proposal attains the support
of a simple majority of the Participating Interests, then the proposal receiving
the largest aggregate Participating Interest vote shall be adopted. In the event
of a tie, the Operator, acting in good faith, shall choose one of the proposals.
The Parties shall execute any and all documents and take such other actions as
may be necessary to effect the surrender. In addition, each Party renounces all
claims and causes of action against Operator and any other Party on account of
any area surrendered in accordance with the foregoing if Petroleum is
subsequently discovered under the surrendered area. A surrender of all or any
part of the Contract Area, which is not required by the Petroleum Contract,
shall require the unanimous consent of the Parties.

EXTENSION OF THE TERM

9.2   A proposal by any Party to seek from CNPC an extension of the term under
the Petroleum Contract for Development Operations, Production Operations or any
phase of the Petroleum Contract, or a proposal to seek from CNPC an extension of
the term of the Petroleum Contract shall be brought before the Operating
Committee pursuant to Part 4.

                                     PART 10

                         TRANSFER OF INTEREST OR RIGHTS

OBLIGATIONS

10.1  Subject to Section 10.3, when a Party transfers any of its Participating
Interest:

      (a)   subject always to the requirements of the Petroleum Contract, the
            transfer of all or part of a Party's Participating Interest shall be
            effective only if it satisfies the terms and conditions of this
            Part;

      (b)   except in the case of a Party transferring all of its Participating
            Interest, no transfer shall be made by any Party which results in
            the transferor or the transferee holding a Participating Interest of
            less than 10 per cent (10%);

      (c)   the transferring Party shall, notwithstanding the transfer, be
            liable to the other Parties for any obligations, financial or
            otherwise, which have vested, matured or accrued under the
            provisions of the Petroleum Contract, the Farmout Agreement or this
            Agreement prior to such transfer. Such obligations shall include,
            without limitation, any proposed expenditure approved by the
            Operating Committee, prior to the transferring Party notifying the
            other Parties of its proposed transfer;

      (d)   the transferee shall have no rights in and under the Petroleum
            Contract, the Contract Area or this Agreement unless and until it
            obtains CNPC/PRC Approval and expressly undertakes in writing to
            perform the obligations of the transferor under the Petroleum
            Contract, the Farmout Agreement and this Agreement in respect of the
            Participating Interest being transferred, to the satisfaction of the
            Parties and furnishes any guarantees required under the Petroleum
            Contract;

                                                                         Page 37
<PAGE>

      (e)   the transferee shall have no rights in and under the Petroleum
            Contract, the Contractor's Rights and Interests or this Agreement
            unless each Party has consented in writing to such transfer, which
            consent shall be denied only if such transferee fails to establish
            to the reasonable satisfaction of each Party its financial or
            technical capability to perform its obligations under the Petroleum
            Contract, the Farmout Agreement and this Agreement;

      (f)   nothing contained in this Part shall prevent a Party from
            Encumbering its Participating Interest for the purpose of security
            relating to finance provided that

            (i)   such Party shall remain liable for all obligations relating to
                  such interest;

            (ii)  the Encumbrance shall be subject to any necessary approval of
                  CNPC, all relevant Governmental Authorities in the PRC and
                  shall be expressly subordinated to the rights of the other
                  Parties under this Agreement; and

            (iii) such Party shall ensure that any such Encumbrance shall be
                  expressed to be without prejudice to the provisions of this
                  Agreement; and

      (g)   any transfer of all or a portion of a Participating Interest, other
            than with or to an Affiliate, shall be subject to the following
            procedure

            (i)   once the transferor Party and a proposed transferee (a third
                  party or a Party) have fully negotiated the final terms and
                  conditions of a transfer, such final terms and conditions
                  shall be disclosed in detail to all other Parties in a written
                  notification from the transferor. Each Party shall have the
                  right to acquire the Participating Interest from the
                  transferor on the same terms and conditions agreed to by the
                  proposed transferee if, within thirty (30) days of
                  transferor's written notification, such Party delivers to all
                  other Parties a counter-notification that it accepts the
                  agreed upon terms and conditions of the transfer without
                  reservations or conditions. If no Party delivers such
                  counter-notification, the transfer to the proposed transferee
                  may be made, subject to the other provisions of this Part 10,
                  under terms and conditions no more favourable to the
                  transferee than those set forth in the notice to the Parties,
                  provided that the transfer shall be concluded within one
                  hundred eighty (180) days from the date of the notice plus
                  such reasonable additional period as may be required to secure
                  any requisite approvals under the Petroleum Contract;

            (ii)  If more than one Party counter-notifies that it intends to
                  acquire the Participating Interest which is the subject of the
                  proposed transfer, then each such Party shall acquire a
                  proportion of the Participating Interest to be transferred
                  equal to the ratio of its own Participating Interest to the
                  total Participating Interests of all the counter-notifying
                  Parties, unless they otherwise agree; and

            (iii) In the event that a Party's proposed transfer of part or all
                  of its Participating Interest involves consideration other
                  than cash then the consideration payable for the Participating
                  Interest shall be allocated a reasonable and justifiable cash
                  value by the transferor in any notification to the other
                  Parties. Such other Parties may satisfy the requirements of

                                                                         Page 38
<PAGE>

                  this Part by agreeing to pay such cash value in lieu of the
                  consideration payable in the third-party offer.

RIGHTS

10.2  Each Party shall have the right, subject to the provisions of Section
10.1, to freely transfer its Participating Interest.

REASSIGNMENT PURSUANT TO SECTION 4.7 OF THE FARMOUT AGREEMENT

10.3  Section 10.1 does not apply to a reassignment of CITIC's Participating
Interest pursuant to Section 4.7 of the Farmout Agreement.

                                     PART 11

                            WITHDRAWAL FROM AGREEMENT

RIGHT OF WITHDRAWAL

11.1  Subject to the provisions of this Part and the provisions of the Petroleum
Contract, any Party may withdraw from this Agreement and the Petroleum Contract
by giving notice to all other Parties stating its decision to withdraw and
specifying a proposed effective date of withdrawal which shall be at least sixty
(60) days but not more than one hundred eighty (180) days after the date of such
notice. Such notice shall be unconditional and irrevocable when given. Subject
to the foregoing and Section 11.5, the effective date of withdrawal for a
withdrawing Party shall be the later of:

      (a)   the date proposed in the notice of withdrawal; or

      (b)   the date that the withdrawing Party has fulfilled its obligations
            under this Part.

PARTIAL OR COMPLETE WITHDRAWAL

11.2  Within thirty (30) days of receipt of a withdrawing Party's notification,
each of the other Parties may also give notice that it desires to withdraw from
this Agreement and the Petroleum Contract. Should all Parties give notice of
withdrawal, the Parties shall proceed to abandon the Contract Area and terminate
the Petroleum Contract and this Agreement. If less than all of the Parties give
such notice of withdrawal, then the withdrawing Party shall take all steps to
withdraw from the Petroleum Contract and this Agreement on the earliest possible
date and execute and deliver all necessary instruments and documents to assign
their Participating Interests to the Parties which are not withdrawing, without
any compensation whatsoever, in accordance with the provisions of Section 11.6.
If any part of the withdrawing Party's Participating Interest remains unclaimed
after sixty (60) days from the date of the first notice of withdrawal, all of
the Parties shall be deemed to have decided to withdraw from the Petroleum
Contract and this Agreement, unless at least one Party agrees to accept the
unclaimed Participating Interest. Any Party withdrawing under this Part shall
withdraw from the entirety of the Contract Area and thus abandon to the other
Parties not joining in its withdrawal all its rights generated by Petroleum
Operations after such withdrawal and all rights in the Contractor's Rights and
Interests.

                                                                         Page 39

VOTING

11.3  After giving its notification of withdrawal, a Party shall not be entitled
to vote on any matters coming before the Operating Committee, other than matters
for which such Party has financial responsibility.

OBLIGATIONS AND LIABILITIES

11.4  A withdrawing Party, prior to its withdrawal, shall satisfy all
obligations and liabilities it has incurred or which are attributable to it
prior to its withdrawal, including, without limitation, any expenditures
budgeted and/or approved by the Operating Committee prior to its written
notification of withdrawal, and any liability for acts, occurrences or
circumstances taking place or existing prior to its withdrawal. Furthermore, any
Encumbrances which the withdrawing Party placed on such Party's Participating
Interest prior to its withdrawal shall be fully satisfied or released, at the
withdrawing Party's expense, prior to its withdrawal. A Party's withdrawal shall
not relieve it from liability to the non-withdrawing Parties with respect to any
obligations or liabilities attributable to the withdrawing Party which are not
identified or identifiable at the time of withdrawal. Notwithstanding the
foregoing, a Party shall not be liable for any operations or expenditures it
voted against if it sends notification of its withdrawal within ten (10) days
(or within twenty-four (24) hours if the drilling rig to be used in such
operation is standing by on the Contract Area) of the Operating Committee vote
approving such operation or expenditure, nor shall such Party be liable for any
operations or expenditures approved by the Operating Committee, excluding those
approved pursuant to Section 11.5, after notice has been given pursuant to
Section 11.1.

EMERGENCY

11.5  Party's notification of withdrawal shall not become effective if prior to
the proposed date of withdrawal a well goes out of control or a fire, blow out,
sabotage or other emergency occurs. The notification of withdrawal shall become
effective only after the emergency has been contained and the withdrawing Party
has paid, or has provided, security satisfactory to the Parties for its
Participating Interest share of the costs of such emergency.

ASSIGNMENT

11.6  A withdrawing Party shall assign its Participating Interest to each of the
non-withdrawing Party which shall be allocated to them in the proportion which
each of their Participating Interests (prior to the withdrawal) bears to the
total Participating Interests of all the non-withdrawing Parties (prior to the
withdrawal), unless the non-withdrawing Parties agree otherwise. The expenses
associated with the withdrawal and assignments shall be borne by the withdrawing
Party.

APPROVALS

11.7  A withdrawing Party shall promptly join in such actions as may be
necessary or desirable to obtain CNPC/PRC Approval in connection with the
withdrawal and assignments. Any penalties or expenses incurred by the Parties in
connection with such withdrawal shall be borne by the withdrawing Party.

                                                                         Page 40
<PAGE>

ABANDONMENT SECURITY

11.8  A withdrawing Party shall provide security satisfactory to the other
Parties to satisfy any such obligations or liabilities which were approved or
accrued prior to notice of withdrawal, but which become due after its
withdrawal, including, without limitation, security to cover the costs of an
abandonment, if applicable. Failure to provide security shall constitute default
under this Agreement. For the purposes of this Section 11.8, "security" means a
standby letter of credit or bond issued by a first class bank.

WITHDRAWAL OR ABANDONMENT BY ALL PARTIES

11.9  In the event all Parties decide to withdraw or are required to do so
pursuant to this Part, the Parties agree that they shall be bound by the terms
and conditions of this Agreement for so long as may be necessary to wind up the
affairs of the Parties with CNPC and the relevant Governmental Authorities in
the PRC, or to satisfy any requirements of applicable law.

RELATIONSHIP OF PARTIES

12.1  Except as otherwise provided in the Petroleum Contract, the rights,
duties, obligations and liabilities of the Parties under this Agreement shall be

loss, cost or liability arising from a failure or refusal to report and
discharge such taxes or satisfy such obligations.

            public and such disclosure is not required pursuant to any rules or
            requirements of any government or stock exchange, then such Party
            shall comply with Section 13.2;

      (h)   to its respective employees for the purposes of Petroleum
            Operations, subject to each Party taking customary precautions to

equitable control methods for determining charges and credits applicable to the
Petroleum Operations according to the relevant provisions of the Joint Operating
Agreement, including the guidelines for accounting settlements in respect of
managing funds and materials, financing and Accounting Records, and for
compiling accounting statements, to the end that no Party shall gain or lose in

accounting in the Joint Account and shall be the currency for the investments
and reimbursements under the Joint Operating Agreement. In case currencies other
than Dollars are used to carry out business activities, the relevant bank
accounts and other current asset and current liability accounts shall be kept
both in Dollars and in the currencies used.

      1.6   Currency translation: For the purpose of accounting, currency

<PAGE>

      The rate of exchange to be used for the conversion into Dollars of cash
calls received in Renminbi shall be the arithmetic average of buying and selling
rates of exchange applicable to any individual or commercial entity quoted by
Bank of China at 11:00 a.m. on the date of receipt of such cash in the
Operator's bank account(s). If the relevant date is a non-business day of the
Bank of China, the rate quoted on the previous business day by the Bank of China
shall apply.

      All other transactions recorded in the Joint Account which are made in
Renminbi shall be translated into and recorded in Dollars at the rate of
exchange as quoted above on the last business day of the previous month, while

shall be recorded in Dollars at the actual cost in Dollars of effecting the
transaction.

      The Operator shall use its best efforts to minimize any exchange loss.

      All gains or losses from currency conversion or translation shall be
recorded in the Joint Account.

      1.7   Foreign exchange business: Foreign exchange business related to the

annual accounting statements.

      1.9   This Accounting Procedure shall apply, mutatis mutandis, to
Exclusive Operations in the same manner that it applies to Joint Operations;
provided, however, that the charges and credits applicable to Consenting Parties
shall be distinguished by an Exclusive Operation Account. For the purpose of
determining and calculating the remuneration of the Consenting Parties,
including the premiums for Exclusive Operations, the costs and expenditures
shall be expressed in Dollars (irrespective of the currency in which the
expenditure was incurred).

      1.10  If it becomes necessary to allocate any costs or expenditures to or

                         ARTICLE 3 PAYMENTS AND ADVANCES

      3.1   Upon approval of any Work Program and Budget and any AFE, if
Operator so requests, each Non-Operator shall advance its share of estimated
cash requirements for the succeeding month's operations. Each such cash call
shall be equal to the Operator's estimate of the money to be spent in the
currencies required to perform its duties under the approved Work Program and
Budget, and the approved AFE, during the month concerned.

      3.2   Each such cash call shall be made in writing and delivered to all
Non-Operators not less than twenty (20) days before the payment due date. The
due date for payment of such advances shall be set by Operator but shall be no
sooner than the first Business Day of the month for which the advances are
required. All advances shall be made without bank charges. Any charges related
to receipt of advances from a Non-Operator shall be borne by that Non-Operator.

      3.3   Each Non-Operator shall wire transfer its share of the full amount
of each such cash call to Operator on or before the due date, in the currencies
requested or any other currencies acceptable to Operator, and at a bank
designated by Operator. If the currency provided by a Non-Operator is other than
the requested currency, then the entire cost of converting to the requested
currency shall be charged to that Non-Operator. All advances shall be made
without bank charges.

      3.4   Notwithstanding the provisions of Article 3.2, should Operator be
required to pay any sums of money for the Joint Operations which were unforeseen
at the time of providing the Non-Operators with said estimates of its
requirements, Operator may make a written request of the Non-Operators for
special advances covering the Non-Operators' share of such payments. Each such
Non-Operator shall make its proportional special advances within fifteen (15)
days after receipt of such notice.

      3.5   Each monthly cash call notice shall clearly indicate the following
information

            3.5.1   All costs and expenses for the cash call to be shared by
                    each Party as shown in the approved Budget and, if required,
                    the approved AFE.

            3.5.2   Detail by major Budget category and relevant AFE
                    identification, if required.

            3.5.3   Funds to be advanced by each Party in the month for which
                    the funds will be used and, for informational purposes, the
                    estimated amount of funds to be advanced by each Party in
                    the following two (2) months.

            3.5.4   The date when funds are to be advanced, currency, and with
                    respect to the account into which the advances are to be
                    made, the name of

                                       5
<PAGE>

                    the bank, its address, account number, name of the account,
                    and particulars required for the advances to be made by wire
                    transfers.

            3.5.5   The Dollar equivalent of the total cash called. The Operator
                    shall also specify the estimated amounts of required
                    Renminbi and Dollars.

      3.6   If a Non-Operator's advances exceed its share of cash expenditures,
the next succeeding cash advance requirements, after such determination, shall
be reduced accordingly. A Non-Operator may request that its excess advances be
refunded. Operator shall make such refund within ten (10) days after receipt of
the Non-Operator's request provided that the amount is in excess of the
requesting Non-Operator's share of the cash advance requirements for the
succeeding month.

      3.7   If Non-Operator's advances are less than its share of cash
expenditures, the deficiency shall, at Operator's option, be added to subsequent
cash advance requirements or be paid by Non-Operator within fifteen (15) days
following the receipt of Operator's billing to Non-Operator for such deficiency.

      3.8   If, under the provisions of the Joint Operating Agreement, Operator
is required to segregate funds received from the Parties, any interest received
on such funds shall be applied against the next succeeding cash call or, if
directed by the Operating Committee, distributed quarterly. The interest thus
received shall be allocated to the Parties on an equitable basis taking into
consideration date of funding by each Party to the accounts in proportion to the
total funding into the account. A monthly statement summarizing receipts,
disbursements, transfers to each joint bank account and beginning and ending
balances thereof shall be provided by Operator to the Parties.

      3.9   If Operator does not request Non-Operators to advance their share of
estimated cash requirements, each Non-Operator shall pay its share of cash
expenditures within twenty (20) Business Days following receipt of Operator's
billing.

      3.10  Payments of advances or billings shall be made on or before the due
date. If these payments are not received by the due date the unpaid balance
shall bear and accrue interest from the due date until the payment is received
by Operator at the Agreed Interest Rate. For the purpose of determining the
unpaid balance and interest owed, Operator shall translate to Dollars all
amounts owed in other currencies using the currency exchange rate readily
available to Operator at the close of the last Business Day prior to the due
date for the unpaid balance as quoted by the applicable authority identified in
Section 1.6 of this Accounting Procedure.

      3.11  Subject to governmental regulation, Operator shall have the right,
at any time and from time to time, to convert the funds advanced or any part
thereof to other currencies to

                                       6
<PAGE>

the extent that such currencies are then required for operations. The cost of
any such conversion shall be charged to the Joint Account.

      3.12  Operator shall endeavor to maintain funds held for the Joint Account
in bank accounts at a level consistent with that required for the prudent
conduct of Joint Operations.

      3.13  If under the Joint Operating Agreement, Operator is required to
segregate funds received from or for the Joint Account, the provisions under
this Article 3 for payments and advances by Non-Operators shall apply also to
Operator.

      3.14  Payments of any advances or billings shall not prejudice the right
of any Non-Operator to protest or question the correctness thereof; provided,
however, all bills and statements rendered to Non-Operators by Operator during
any calendar year shall conclusively be presumed to be true and correct after
twenty-four (24) months following the end of such calendar year, unless within
the said twenty-four (24) month period a Non-Operator takes written exception
thereto and makes claim on Operator for adjustment. Failure on the part of a
Non-Operator to make claim on Operator for adjustment within such period shall
establish the correctness thereof and preclude the filing of exceptions thereto
or making claims for adjustment thereon. No adjustment favorable to Operator
shall be made unless it is made within the same prescribed period. The
provisions of this paragraph shall not prevent adjustments resulting from a
physical inventory of the property as provided for in Article 4.7. Operator
shall be allowed to make adjustments to the Joint Account after such twenty-four
(24) month period if these adjustments result from audit exceptions outside of
this Joint Operating Agreement, third party claims, or Governmental Authority or
CNPC requirements. Any such adjustments shall be subject to audit within the
time period specified in Article 8.
