                 4.3.3      In the event that Seller and Buyer cannot agree upon
                            any matter to which the statement referred to in
                            Clause 4.3 relates, the undisputed amount shall be
                            paid and the disputed amounts shall be referred for
                            resolution to an independent chartered accountant
                            appointed by Seller and Buyer or in the event of
                            Seller and Buyer differing as to such appointment by
                            the President for the time being of the Institute of
                            Chartered Accountants of England and Wales. The
                            accountant shall be afforded such access to books,
                            records, accounts and documents in the possession of
                            each of the Parties as he may reasonably request.
                            For the purposes of this Agreement, the accountant
                            so appointed shall be deemed to be acting as an
                            expert and not as an arbitrator, and the decision of
                            the accountant so appointed shall, in the absence of
                            manifest error, be final and binding on Seller and
                            Buyer and


                                                                             -7-


   8



         settlement of any outstanding amount shall be made within (5) Business
         Days of such decision. The costs of the accountant shall be borne
         equally by Seller and Buyer.

                 4.3.4      The Buyer shall pay to Seller or Seller shall pay to
                            the Buyer (as the case may be) interest on such
                            further sums as may be payable from the date such
                            sums are due to be paid to the date the sums are
                            actually paid (both dates inclusive) at a rate per
                            annum equal to one (1) percentage point above the
                            Reference Interest Rate calculated on a daily basis
                            using simple interest.

         4.4     Interim Period Adjustment

                 4.4.1      Buyer shall pay Seller the amount of all obligations
                            and liabilities pertaining to the Asset and Licence
                            paid by Seller in respect of the Interim Period.

                 4.4.2      Seller shall pay to the Buyer the amount of all
                            receipts pertaining to the Asset and Licence
                            received by Seller in respect of the Interim Period.

                 4.4.3      For the purposes of this Clause, obligations and
                            liabilities will include, inter alia, cash calls for
                            operating costs and receipts will include, inter
                            alia, actual proceeds from the sale of Petroleum
                            produced after the Effective Date. The Buyer will
                            refund an amount equal to the Petroleum Revenue Tax
                            ("PRT") and Corporation Tax ("CT") at the assumed
                            rate of twenty-eight percent (28%) incurred by the
                            Seller relating to the Asset for the period between
                            the Effective Date and the Completion Date. For
                            purposes of clarity, the PRT incurred by the Seller
                            will be that amount of PRT actually paid or accrued
                            by the Seller and CT incurred by the Seller will be
                            a notional calculation based on the assumed rate of
                            twenty-eight percent (28%) times receipts less
                            revenue expenditures and PRT paid or accrued but
                            with no capital allowances on any capital
                            expenditure during the Interim Period.

                 4.4.4      If the Seller does not incur liability to PRT and CT
                            relating to the Asset for the period between the
                            Effective Date and the Completion Date, which
                            situation shall arise if the Inland Revenue accepts
                            the Effective Date as the date of transfer

                                                                             -8-

         for tax purposes, then the sums repaid by the Buyer to the Seller and
         by the Seller to the Buyer pursuant to the foregoing provisions of this
         Clause 4.4 shall be deemed to have been incurred or received (as the
         case may be) directly by the Buyer as if the transfer of the Asset had
         taken place on the Effective Date for tax purposes. The Buyer may, at
         its own costs and expense with such assistance from the Seller as Buyer
         may reasonably request, seek to obtain the consent of the Inland
         Revenue to accept the Effective Date as the date of transfer for tax
         purposes and if such consent is obtained, the Seller agrees to file its
         PRT and CT returns accordingly and notwithstanding Clause 4.2 any sums
         that become payable pursuant to this Clause 4.4 shall not be an
         adjustment to the consideration.

                 4.4.5      The amounts set out above shall be set out in a
                            statement to be prepared and given by Seller to the
                            Buyer within sixty (60) days after Completion.
                            Verification, including the right of audit of said
                            statement, shall be carried out within sixty (60)
                            days of receipt of such statement and subject to the
                            provisions of Clause 4.4.6, settlement of the
                            amounts detailed in the statement as varied by any
                            adjustment agreed between Seller and Buyer shall be
                            made within the said sixty (60) day period.

                 4.4.6      In the event that Seller and the Buyer cannot agree
                            upon any matter to which the statement referred to
                            in Clause 4.4.5 relates, the undisputed amounts
                            shall be paid and the disputed amounts shall be
                            referred for resolution to an independent chartered
                            accountant appointed by Seller and Buyer or, in the
                            event of Seller or Buyer differing as to such
                            appointment, by the President for the time being of
                            the Institute of Chartered Accountants of England
                            and Wales. The accountant shall be afforded such
                            access to books, records, accounts and documents in
                            the possession of each of the Parties as he may
                            reasonably request. For the purposes of this
                            Agreement, the accountant so appointed shall be
                            deemed to be acting as an expert and not as an
                            arbitrator, and the decision of the accountant so
                            appointed shall, in the absence of manifest error,
                            be final and binding on Seller and the Buyer and
                            settlement of


                                                                             -9-


   10



                            any outstanding amount shall be made within five (5)
                            business days of such decision. The costs of the
                            accountant shall be borne equally by Seller and the
                            Buyer.

         4.5     INTEREST

                 4.5.1      In the event that Completion occurs after the
                            Effective Date, the consideration shall be treated
                            as having become due on the Effective Date and the
                            Buyer shall pay to the Seller on the Completion
                            Date, in addition to the consideration, interest on

                            preceding the Completion Date (both dates
                            inclusive).

                 4.5.2      Interest shall be paid on any payments due under
                            Clause 4.4.1 and Clause 4.4.2 at a rate per annum
                            equal to the Reference Interest Rate calculated on a
                            daily basis using simple interest for the number of
                            days elapsed between the time receipts are received
                            and payments are made in accordance with Clause
                            4.4.1 and Clause 4.4.2.

         4.6     Any and all amounts to be paid pursuant to this Agreement shall
                 be paid in same day funds to the Seller's account as the Seller

   11



                 5.1.3      not without prior written consent of Buyer (not to

                            proposal to be voted upon by the operating committee
                            established under the Joint Operating Agreement; and

   12

                 each other all such additional instruments and to do all such

7.       REPRESENTATIONS, WARRANTIES AND UNDERTAKINGS

         7.1     Subject to the provisions of Clause 7.3, Seller hereby
                 represents and warrants to Buyer in the terms set out in
                 Schedule 2 and such representations and warranties shall be
                 deemed to be repeated immediately prior to Completion on the
                 basis that all references to "the date hereof" shall be deemed
                 to refer to the Completion Date.

         7.2     Buyer hereby represents and warrants to the Seller in the terms
                 set out in Schedule 3 and such representations and warranties
                 shall be deemed to be repeated immediately prior to Completion
                 on the basis that all references to "the date hereof" shall be
                 deemed to refer to the Completion Date.

                                                                            -13-


   14



         7.3     Except with regard to the warranties 1, 2, 3 and 21 in Schedule
                 2, the Buyer shall not be entitled to claim that any fact or
                 matter constitutes a breach of the representations and
                 warranties set out in Schedule 2 hereto to the extent that such
                 fact or matter is fairly disclosed in the Data Room Documents
                 relating to the Asset.

         7.4     Seller shall ensure that the representations and warranties
                 referred to in Clause 7.1 are true and accurate on the
                 Completion Date but if notwithstanding such efforts any matter
                 or thing occurs of which Seller is aware and which would be
                 inconsistent with any of such representations and warranties on
                 the Completion Date Seller shall promptly notify Buyer thereof.

         7.5     In the event of any matter or thing materially inconsistent
                 with any of the representations or warranties given by Seller
                 in or pursuant to this Agreement being notified by Seller to
                 Buyer prior to Completion (or Buyer otherwise becoming aware of
                 such matter or thing) and such matter or thing continuing to be
                 materially inconsistent at the date agreed for Completion,
                 Buyer shall not be bound to complete the acquisition of the
                 Asset and Buyer may by notice in writing to Seller prior to
                 Completion rescind this Agreement. Such right of rescission
                 shall be Buyer's only remedy, and there shall be no liability
                 on the part of Buyer or Seller with respect to such matters or
                 things whether or not this Agreement is rescinded.

         7.6     The maximum aggregate liability of Buyer or Seller as the case
                 may be, for all claims for breach of any representation or
                 warranty under Clauses 7.1 or 7.2 arising after Completion
                 shall in no event exceed the aggregate of the amount of
                 consideration, interest (if any) paid thereon, and any amounts
                 paid by Buyer pursuant to Clause 4.2.

         7.7     If Buyer receives any claim or becomes aware of any fact which
                 may result in Buyer having a claim against Seller under this
                 Clause, Buyer shall promptly notify Seller thereof in writing
                 and Seller shall be entitled to require Buyer to take any
                 reasonable action it may request to resist such claim and Buyer
                 will give Seller all co-operation, access and assistance for 
                 the purposes of considering such claim as they may reasonably
                 require; provided always that Buyer is indemnified to its
                 reasonable satisfaction by Seller against all claims, costs,
                 expenses, damages or losses which may thereby be incurred.
        
                                                                            -14-


   15




         7.8     Where any statement in Schedule 2 is qualified by the
                 expression "so far as Seller is aware" or any similar
                 expression, that statement shall be deemed to include an
                 additional statement that it has been made after due and
                 careful enquiry.

         7.9     The Seller acknowledges that the Buyer has entered into this
                 Agreement in reliance upon the warranties and has been induced
                 by the warranties to enter into this Agreement.

         7.10    The benefit of the warranties may be assigned in whole or in
                 part to any assignee of the Purchaser permitted in accordance
                 with Clause 17.

         7.11    No claim may be made by either Party for a breach of any
                 representation or warranty made by Seller or Buyer, in the case
                 of a claim relating to taxes following the seventh anniversary
                 of the Completion Date and in the case of any other claim
                 following the second anniversary of the Completion Date, and no
                 liability shall attach to Seller or Buyer, as the case may be,
                 in respect of any such claim until the aggregate amount of all
                 such claims against Seller or Buyer, as the case may be,
                 exceeds one million (1,000,000 pounds sterling) U.K. pounds 
                 sterling in which event Buyer or Seller, as the case may be, 
                 shall be liable for the whole of such amount and not merely 
                 the excess.

         7.12    Any claim for breach of warranty under Schedule 2, including
                 but not limited to lost production or loss of profits shall be
                 limited in any recovery to the economic impact on Buyer based
                 on Buyer's economic assumptions used to develop the
                 consideration paid for the Asset.

8.       TAXATION

         8.1     Seller and Buyer acknowledge that:

                 (a)        the consideration represents expenditure incurred by
                            Buyer in acquiring plant and machinery relating to
                            the Asset to the extent of the amount of the 
                            Seller's gross expenditure incurred with respect to
                            the Asset in acquiring plant and machinery less any
                            relevant disposal proceeds up to but not including 
                            the Completion Date, and the remainder of the 
                            consideration relates to the balance of the Asset 
                            including the Licence. Seller covenants that it 
                            will treat the said allocated expenditures on 
                            plant and machinery as disposal proceeds for the  
                            purposes of Section 24(6) Capital Allowance Act 
                            1990, and Buyer covenants that it will treat

                                                                            -15-


   16



                            such amount as capital expenditure incurred for the
                            purposes of the Capital Allowance Act 1990, and the
                            Seller will provide details of such amount to the
                            Buyer as soon as reasonably practicable after
                            Completion.
        
                 (b)        subject to Clause 4.4.4 any sums that may become
                            payable pursuant to Clause 4.4 and shall be added to
                            or subtracted from the balance of the Asset;

                 (c)        no part of the consideration or other payments
                            pursuant to Clause 4.2 whether or not attributed to
                            the balance of the Asset, shall be treated as a
                            reimbursement of expenditure which the Seller has
                            incurred whether comprising intangible drilling
                            expenditure or otherwise; and

                 (d)        they will each present their returns for tax
                            purposes on the basis stated above and that they
                            will use all reasonable endeavors to agree with the
                            Oil Taxation Office the figures so presented.

         8.2     The Seller shall prepare and the Seller and the Buyer shall
                 deliver to the Board of Inland Revenue in a timely fashion a
                 notice in accordance with paragraph 3 of Schedule 17 to the
                 Finance Act 1980 and shall not make an application under
                 paragraph 4 of the said Schedule for the provisions of Parts II
                 and III of the said Schedule not to apply to the transfer of
                 the Asset.

         8.3     Buyer confirms that it is registered for VAT in the UK and that
                 it intends to use the assets acquired for its own trade of
                 exploration/exploitation. Seller and Buyer confirm that neither
                 of them has elected to waive exemption under section 51 and
                 paragraphs 2-4 Schedule 10 Value Added Tax Act 1994 in relation
                 to the Asset and they each intend that the sale shall be
                 treated as a transfer of part of the business of the Seller as
                 a going concern within the terms of Section 49 of the Value
                 Added Tax Act 1994 and of Article 5 Value Added Tax (Special
                 Provisions) Order 1992, hereinafter referred to as "Article 5".

                 In the event that Seller is advised in writing by H.M. Customs
                 and Excise that the transaction is subject to VAT and if called
                 upon to do so by Seller, Buyer agrees to pay to Seller, on
                 presentation of a valid VAT invoice, any amounts due in respect
                 of VAT relating to this transaction set out in such invoice and
                 within thirty (30) days of demand.

                                                                            -16-


   17



         8.4     It is agreed that:

                 (a)        the Seller shall cooperate with any reasonable
                            request by the Buyer who may, at its own cost and
                            expense, send to HM Customs & Excise a letter
                            seeking a ruling as to whether the sale of the Asset
                            is to be treated as a transfer of part of the
                            business of the Seller as a going concern and the
                            Seller will assist the Buyer with all reasonable
                            endeavours to obtain such a ruling as soon as
                            reasonably practicable;

                 (b)        if the sale is to be so treated the Seller shall
                            send to HM Customs & Excise a letter seeking
                            confirmation that Seller be permitted to keep and
                            preserve the records for the period prior to the
                            date of Completion referred to in Section 49 of the
                            Value Added Tax Act 1994 relating to the Asset and
                            if such confirmation is not given, the Seller shall
                            transfer to the Buyer all such records as relate to
                            the Asset;

                 (c)        if HM Customs & Excise state in writing that the
                            sale of the Asset does not fall within the
                            provisions of Article 5 the Seller shall cooperate
                            with any reasonable request by the Buyer who may, at
                            its own cost and expense, seek a ruling from HM
                            Customs & Excise that the sale is outside the scope
                            of VAT being a supply of services in relation to
                            land situated outside the UK and that no VAT will
                            become due on this transaction;

                 (d)        if HM Customs & Excise state in writing that the
                            sale of the Asset is taxable, the Seller shall
                            cooperate with any reasonable request by the Buyer
                            who may, at its own cost and expense, promptly take
                            all steps to dispute such statement. In the event
                            that it is subsequently held or decided that no VAT
                            is payable in respect of the sale of the Asset and
                            the Seller receives any repayment or credit in
                            respect of an amount which had been paid by the
                            Buyer as VAT to the Seller, the Seller shall
                            promptly reimburse such amount to the Buyer; and

                 (e)        the Seller and Buyer shall copy each to the other
                            all relevant correspondence between either of them
                            and HM Customs and Excise.

                                                                            -17-

         9.1     Notwithstanding any other provision of this Agreement, in the
                 event that any audit in respect of any period prior to the

                 audit or request to the extent that they relate to periods
                 prior to the Effective Date; and (a) to the extent that any
                 payment in respect thereof is made by the Operator such payment
                 shall be made to Seller and (b) to the extent that any payment
                 is required to be made in respect thereof to the Operator, such
                 payment shall be made by Seller to Buyer.

         9.2     To the extent that the Seller shall have any information,
                 records or data in respect of the Asset or the Asset Documents
                 for periods prior to the Effective Date that it has not made

                 extent that the Buyer shall request the assistance of the
                 Seller in the interpretation and construction of the same and

                 insurance coverage on the Asset protecting the other party for
                 any loss, damage, liability or expense for which such party may

                 provided in Clauses 10.4, 10.5, 10.6 and 10.7 herein. Both
                 Buyer and Seller shall be free to arrange such insurance

                 each may deem advisable for their own account and at their own
                 expense and shall cooperate with each other to ensure, as far
                 as practicable, that the insurance coverage held by either
                 party is appropriately coordinated and does not conflict.

         10.2    Upon execution of this Agreement, Seller shall furnish all such
                 information as Buyer may reasonably request in order to enable

                 right of contribution from the Buyer's insurance, and Buyer
                 shall use reasonable efforts to ensure its policies providing
                 insurance coverage on the Asset are endorsed such that the

                 contribution from the Seller's insurance.

         10.4    During the Interim Period, Seller shall maintain or obtain or

                 rules and regulations and as may be required by any Asset
                 Document. Buyer shall be named as an additional insured and

                 interruption insurance effected by the Seller, as an additional
                 assured and loss payee during the Interim Period, in respect of
                 Buyer's rights and interest under this Agreement. Seller shall
                 provide certification or other documentation evidencing that
                 the Buyer has been included as an additional insured and loss
                 payee as soon as reasonably practicable.
