         "Consideration") representing an equal amount in respect of each of
         the Sale Shares and payable in full by bank transfer on Completion.

2.1.2    On December 18, 1996 Den Danske Bank (the "Bank") has provided Company
         with an overdraft facility of USD 1 million (the "Facility"). Vendor
         shall procure that any and all amounts drawn under the Facility and

         in each of the respective Articles.

         In the event that the audit reveals either an underpayment or
         overpayment of the consideration as provided in either of said
         Articles then Purchaser or Vendor (as the case may be) will pay to the
         other Party an amount equal to the said underpayment or overpayment

         agreement then either Party may be at liberty to submit the dispute to
         the relevant English Court for determination.

2.2      Vendor and Purchaser shall bear their own respective fees and expenses
         and Taxation incurred in connection with the transactions contemplated
         by this agreement, it being acknowledged that any liability for stamp
         or share duty payable on the transfer of the Sale Shares shall be for
         the account of Purchaser.

              contract or any other form of legal obligation the value of which
              to Company and the Joint Venturers together will or is likely to
              be less than one million United States dollars (US$ 1,000,000) or

ARTICLE 6 - WARRANTIES

6.1      Vendor warrants to and in favour of Purchaser as follows:

         a)   the execution, delivery and performance of this agreement and of 
              the terms, conditions, covenants, warranties and agreements
              herein contained on the part of Vendor have been duly authorised
              and approved so as to constitute valid and binding obligations;

   10




         b)   the sale hereby agreed does not give rise to the contravention of 
              or failure to comply with any statute, statutory instrument,
              regulation, by-law or rule of law for the time being in force to
              which Vendor or Company is subject;

         c)   Vendor has furnished to Purchaser all material information, of 
              which Vendor is aware, regarding the business and financial
              condition of Company;

         d)   all written information material to the subject matter of this
              agreement given by Vendor or any director, officer, auditor,
              servant or agent of Vendor or Company or any of Vendor's other
              subsidiaries to Purchaser in the course of the negotiations
              leading to this agreement and the statements contained in the
              recitals and schedules hereto, in particular without limitation,
              other than the limitation of liability as specified in Article
              6.6, the warranties contained in the Second Schedule hereto, are
              true and accurate in all material respects;

         e)   the warranty set out in Article 11.

6.2      The foregoing warranties set out in Articles 6.1 a)-e) (the
         "Warranties") shall be deemed to be repeated by Vendor to and in
         favour of Purchaser on Completion with reference to the facts and
         circumstances then subsisting PROVIDED THAT if there should between
         the date of this agreement and the date of Completion occur a breach
         of any of the warranties Vendor shall disclose such breach to
         Purchaser and if Purchaser then proceeds to complete the purchase of
         the Sale Shares it shall be deemed to have waived all its rights to
         rescind this agreement in relation to that breach or to claim damages
         in respect of it.

6.3      Vendor acknowledges that Purchaser is entering into this agreement in
         reliance upon the Warranties and disclosure of information of Vendor
         herein contained.

6.4      Each of the Warranties contained in Article 6.1 and in the Second
         Schedule hereto is a separate warranty and independent of each of the
         other warranties.

6.5      The Purchaser acknowledges and agrees that:

         (a)  the Warranties are the only representations, warranties or other
              assurances of any kind given by or on behalf of the Vendor and on
              which the Purchaser may rely in entering into this agreement;

         (b)  no other statement, promise or forecast made by or on behalf of
              the Vendor may form the basis of, or be pleaded in connection
              with, any claim by the Purchaser under or in connection with this
              agreement:

         (c)  any claim by the Purchaser or any person deriving title from it
              in connection with the Warranties (a "Warranty Claim") shall be
              subject to the following provisions of this Article; and

         (d)  at the time of entering into this agreement it is not aware of
              any matter or thing which is inconsistent with the Warranties or
              constitutes a breach of any of them.

   11





6.6      The liability of the Vendor under or in respect of the Warranties 
         shall be limited as follows:

         (a)  there shall be disregarded for all purposes any breach of the
              Warranties in respect of which the amount of the damages to which
              the Purchaser would otherwise be entitled is less than US$ 10,000
              (and for this purpose a series of individual claims arising from
              a common matter, act, omission or circumstance shall be treated
              as one claim);

         (b)  the Purchaser shall not be entitled to recover any damages in
              respect of any breach or breaches of the Warranties unless and
              until the aggregate liability of the Vendor in respect of all
              Warranty Claims exceeds in aggregate the sum of US$ 50,000;

         (c)  the maximum aggregate liability of the Vendor in respect of all 
              and any Warranty Claims shall not exceed USD 9.3 million;

         (d)  notwithstanding any other provision of this agreement Vendor
              shall under no circumstances be liable to Purchaser for any
              special, consequential or indirect damages or loss of profit or
              turnover.

6.7      The Purchaser shall not be entitled to make any Warranty Claim:

         (a)  to the extent that sufficient provision or allowance for the
              matter or liability which would otherwise give rise to the claim
              in question has been made in Company's last audited accounts;

         (b)  if the claim would not have arisen but for a change in
              legislation made after the date of this agreement (whether
              relating to taxation, rates of taxation or otherwise) or the
              withdrawal of any extra-statutory concession previously made by
              any taxing authority (whether or not the change purports to be
              effective retrospectively in whole or part).

6.8      If the Purchaser or the Company becomes aware of a matter which could
         give rise to a Warranty Claim the Purchaser shall give notice of the
         relevant facts to the Vendor as soon as reasonably practicable and in
         any event within 30 days of the Purchaser becoming aware of those
         facts and if the Warranty Claim in question is as a result of or in
         connection with a liability or alleged liability to an employee or to
         a third party:

         (a)  the Purchaser shall procure the Company to take such action to
              avoid, dispute, resist, appeal, compromise or contest the
              liability as may be reasonably requested by the Vendor; and

         (b)  subject to being indemnified to its reasonable satisfaction
              against all costs and disbursements of and in relation to any
              legal proceedings which may be instituted at the request of the
              Vendor in respect of such claim or matter, shall not (and shall
              procure that the Company shall not) pay, accept or compromise any
              such claim without giving the Vendor a reasonable opportunity to
              resist them.

6.9      The Vendor shall cease to have any liability under or in respect of 
         the Warranties:

   12





         (a)  six years from the date of Completion of this agreement in respect
              of the Warranties relating to taxation; and

         (b)  two years from that date in respect of any other Warranties.

6.10     Without prejudice to the Purchaser's duty to mitigate any loss in
         respect of any breach of the Warranties, if in respect of any matter
         which would otherwise give rise to breach of the Warranties the
         Company is entitled to claim under any policy of insurance, the amount
         of insurance monies which the Company receives from the insurer shall
         reduce pro tanto or extinguish the claim for breach of the Warranties
         in relation to any such matter.

ARTICLE 7 - CONFIDENTIALITY

7.1      Except the necessary disclosures to the Thai authorities, pending
         Completion neither Party hereto shall disclose the contents or import
         of this agreement or make any announcement or statement concerning the
         sale and purchase hereby agreed to any person (except the legal
         representative of a Party hereto or as required by law or any stock
         exchange) without the previous consent in writing of the other Party
         hereto.

7.2      Pending Completion and thereafter Vendor shall not directly or
         indirectly in any part of the world use or attempt to use any
         Proprietary Information in any manner which will or may cause loss or
         damage whether direct or indirect to the business or financial affairs
         of Company except with the previous consent in writing of Purchaser.

7.3      The provisions of this Article shall continue to apply after
         Completion without limit in time or place but shall cease to apply to
         any specific item of Proprietary Information immediately upon the same
         becoming known generally by persons, other than Vendor or its
         affiliated or associated companies, involved in any business similar
         to that of Company or disclosed in a publication by Company or by any
         other person or persons otherwise than in contravention of the
         provisions of this Article.

ARTICLE 8 - GUARANTEES

8.1      Purchaser shall use all reasonable endeavours to procure the release
         of the guarantee by Vendor to the Thai Department of Mineral Resources
         date May 24, 1991.

8.2      At Completion Purchaser shall release Vendor of the guarantee by
         Vendor to Purchaser pursuant to Article 23 of the JOA.

8.3      Pending release of the guarantees mentioned under Article 8.1 and
         Article 8.2 above Purchaser shall indemnify and keep indemnified
         Vendor against all losses, claims, demands, damages, costs and
         expenses arising in relation to an event occurring after Completion
         and prior to such release, which Vendor may incur or suffer under or
         pursuant to such guarantees and under or pursuant to Article 15.3 of
         the Joint Operating Agreement.

   13





ARTICLE 9 - GENERAL PROVISIONS

9.1      Purchaser acknowledges and agrees that it has not relied on any
         covenant, undertaking, representation or warranty given or made by or
         on behalf of Vendor in entering into this agreement which is not
         contained or referred to in this agreement and that the provisions of
         this agreement represent the whole of the agreement between the
         parties.

9.2      According to the Concession, Company is operator for Block B8/32 
         excluding the Tantawan sub-area as defined in the Concession.

         There are no provisions in the Joint Operating Agreement for removal
         of operator or obligation for operator to resign as operator due to
         the transfer of beneficial ownership of the shares of Company.

         Should, however, the Government of the Kingdom of Thailand, including
         the Ministry of Industry or any of its departments or agencies, for
         whatever reason before or after Completion, require that Company
         resign its operatorship (whether or not pursuant to a provision of law
         or of any contract) or assert that Company should resign its
         operatorship, Vendor shall have no liability whatsoever as a result
         and Purchaser shall not be entitled to make any claim for breach or
         alleged breach of any warranty or representation made in this
         agreement, provided that Vendor shall use its reasonable endeavours to
         procure that the said Government agrees to Company's remaining as
         Operator. In the event that any other party without due cause asserts
         that Company should resign its operatorship Vendor shall have no
         liability whatsoever as a result. Furthermore, this agreement shall
         not be capable of being rescinded as a result and the terms of this
         agreement shall remain unaffected by any such requirement or
         assertion.

9.3      The rights and benefits conferred by this agreement on any Party
         hereto are personal to that Party and may not be assigned or
         transferred by that Party except as herein provided or with the
         previous consent in writing of the other Party hereby.

9.4      In case any provision of this agreement is found to be invalid,
         illegal or unenforceable for whatsoever reason then to the extent only
         of such invalidity, illegality or unenforceability such provision
         shall be deemed to be severed from this agreement and the remaining
         provisions of this agreement shall continue in full force and effect
         unimpaired by such severance. In such event the Parties shall
         negotiate, in good faith, any adjustments to be made to this agreement
         with a view to reestablishing the `balance' between the Parties in
         respect of the provisions affected, however, preserving the existing
         provisions to the greatest possible extent.

ARTICLE 10 - NOTICES

10.1     Any notice or communication authorised or required to be given under
         or pursuant to this agreement shall be in writing or some facsimile of

ARTICLE 11 - PROPER CONDUCT

11.1     Vendor undertakes that Company has complied and shall prior to
         Completion comply with all applicable laws dealing with improper or
         illegal payment, gifts or gratuities. In any event, Vendor undertakes
         that Company has not paid and shall not prior to Completion pay,
         promise to pay or authorise the payment of any money or anything of
         value, directly or indirectly to any person (whether a governmental
         official or private individual) for the purpose of illegally or
         improperly inducing any official or political party or official
         thereof in obtaining or retaining business. Furthermore, Vendor
         undertakes that Company has not taken and will not prior to Completion
         take any action, or fail to take any action, which act or failure to
         act would subject Company or the holder of the Sale Shares to
         liability under the laws of its country or domicile dealing with
         improper payments as described in this subsection. Any breach of this
         obligation shall be a material breach of this agreement and shall
         entitle Purchaser to terminate this agreement.

11.2     Purchaser warrants and represents to Vendor, and Vendor in relation to
         itself and Company warrants and represents to Purchaser, that prior to
         the execution of this agreement it has not taken any action, or failed
         to take any other action, with respect to the transaction contemplated
         herein which act or failure to act would have violated Article 11.1.

ARTICLE 12 - PROPER LAW AND JURISDICTION

12.1     This instrument shall be governed and construed in accordance with 
         English law.

12.2     The parties hereto shall submit to the jurisdiction of the English
         Courts in respect of all disputes arising out of this agreement.

Dear Khun Suradej,

As you have previously been informed, a sale of Maersk Oil (Thailand) Ltd.
(MOTL) is currently being considered. The company in which you are employed may
change ownership.

Therefore, in consideration of your choosing to remain an employee of MOTL and
your are not giving notice of termination of your employment contract,
effective prior to April 1, 1997, you are guaranteed:

         1)      a bonus of 10 (ten) months of your base salary, payable not 
                 later than in April, 1997 and

         2)      employment through December 31, 1996 even in the event that 
                 sale of MOTL is effective before that date.

If MOTL gives notice of termination of your employment contract (for any reason
other than breach of your employment contract) with effect from January 1, 1997
or later, you will receive the above bonus within one month of the effective
date of your termination.

If you give notice of termination of your employment contract with MOTL, with
effect from any date prior to April 1, 1997 or if you breach your employment
contract and we are thus forced to terminate your employment contract, you will
not receive the above bonus nor the salary for the unearned portion of the
guaranteed employment period.

Furthermore, if your employment is terminated for any reason other than breach
of your employment contract, all other bonuses and benefits to which you are
entitled under your employment contract or under the law will remain
unaffected.

We do hope that irrespective of the uncertainty created by our sales effort,
you will remain an employee of Maersk Oil (Thailand) Ltd., and that our
hitherto good cooperation will continue in good faith.


                                On behalf of Maersk Oil (Thailand) Ltd.
