Without prejudice to each Buyer's obligation and liability to Sellers as described in this Clause 2.5, it is recognised and agreed between Buyers that if one Buyer is unable to take wholly or partially it's portion of the Natural Gas from Sellers, the other Buyer shall be allowed to take and purchase such equivalent portion from Sellers under this Agreement. 2.6 Buyer or Buyers shall maintain any license, permit, agreement or other authorization which is or may be necessary to enable it or them to fulfill all of its or their obligations under this Agreement. ARTICLE III INITIAL FIELD RESERVES 3.1 The initial Field Reserves as of December 31, 1997 are certified and agreed to be two decimal nine five (2.95) Trillion Cubic Feet inclusive of up to twenty three (23) percent of carbon dioxide which is calculated based on the certified reserves by third party of two decimal three six (2.36) Trillion Cubic Feet (Proved Natural Gas Reserves). ARTICLE IV QUANTITIES 4.1 Commencing from the Effective Date of this Agreement, Sellers shall at their own expense, proceed with the construction and installation of facilities enabling them to produce and deliver to Buyers the Contractual Delivery Capacity as described in Sub-clause 4.7.1 hereafter. 4.2.1 (a) The Date of Commencement of Delivery ("DCD") shall be the date of first delivery of Natural Gas from Sellers to Buyer or Buyers under this Agreement and shall occur between April 1, 2002 and June 30, 2002. Prior to November 1, 2000, the Parties shall mutually agree to a specific Day within the above ninety one (91) Day period for the DCD. In the event the Parties cannot agree on a mutually acceptable date, the DCD shall, for all intents and purposes, be deemed to be June 30, 2002. Any deferment of the DCD due to an event constituting Force Majeure in accordance with Article XVI shall be limited to the number of Days and part Days actually lost in consequence of the occurrence of such an event. (b) Buyers undertake to use their best efforts to prevent any delays and meet the above DCD date. In this regard, the Parties recognize Buyers' obligations to obtain the necessary and required approvals from the Office of Environmental Policy and Planning of Thailand ("EIA Approval") for the installation and construction of facilities downstream of the Delivery Point(s). These facilities are the Gas Separation Plant ("GSP") and the "Pipeline System" consisting of the gas transportation pipelines from the Delivery Point(s) up to the Malaysian Border, the carbon dioxide removal facilities, the slug catcher, the dew point control facilities, and the mercury removal unit if required. Accordingly, to ensure that the EIA Approval is obtained in good time for the GSP and the Pipeline System, Buyers shall undertake the following: (i) develop plans and key milestones of the EIA Approval process with the aim of obtaining the same no later than September 30, 2000 ("Target Date"); (ii) ensure that all the requirements are fulfilled and complied with, that the necessary follow-up steps including but not limited to, discussions and dialogues with the relevant governmental authority, are taken to expedite the approval process, and that Sellers shall be allowed to participate in such sessions together with Buyers; (iii) closely monitor the progress of the EIA Approval process; and provide monthly updates to Sellers on the matter; and (iv) ensure that Sellers are given notification as soon as practicable of all public meetings concerning the EIA Approval. However, in the event that by January 2, 2000 Buyers anticipate that the EIA Approval would likely be delayed beyond the Target Date, Buyers shall immediately notify Sellers of such anticipated delay. Such notice shall include full information about the circumstances for the delay and a statement of steps and time believed necessary to obtain the EIA Approval and the effect on the DCD. If Buyers have taken the necessary steps to obtain the EIA Approval (including all the steps described in (i) to (iv) above), then Buyers' inability to meet the deemed DCD date as a direct result of the delay in obtaining the EIA Approval for the Pipeline System shall, notwithstanding anything to the contrary under Article XVI on the definition of Force Majeure, be treated as a Force Majeure event under this Agreement to the extent it delays the completion of the Pipeline System . (c) Notwithstanding the declaration of Force Majeure pursuant to Sub-clause 4.2.1(b) above, Buyers shall exercise their reasonable endeavours and take the necessary steps to mitigate the adverse impact to Sellers that could reasonably be attributed to the delay caused by such event and shall undertake to discuss with Sellers on appropriate remedial arrangements. 4.2.2 The Run-in-Period shall mean the period of time between the DCD and the CDD, and shall extend for ninety (90) Days, which includes a period of time for the Test Period. 4.2.3 For the purpose of testing the facilities required for the performance of obligations of Buyer or Buyers and Sellers during the RIP there shall be a Test Period of seventy-two (72) hours starting from or after the DCD until Natural Gas has flowed continuously at the DCQ of one hundred ninety five (195) million Cubic Feet per Day for a total of seventy-two (72) hours in conformance with the quality specifications and pressure requirements. If Sellers are unable to complete the continuous seventy-two (72) hour Test Period, for whatever reason other than due to Buyer or Buyers' inability to take Natural Gas, the test shall be restarted. If within the seventy-two (72) hour Test Period, Buyer or Buyers is/are unable to take Natural Gas, for whatever reason, the test shall be suspended and restarted at the end of the interruption, but only for the number of hours necessary to make up the total period of seventy-two (72) hours. 4.2.4 During the RIP and the Test Period Sellers and Buyers shall use their reasonable endeavors to deliver and accept Natural Gas respectively; but the Take-or-Pay provisions of Sub-clauses 4.9.2 and 4.9.3 and the default provisions of Article XV shall not apply. Payment for such Natural Gas delivered to Buyer or Buyers shall be in accordance with Clause 9.7. During the RIP, Sellers shall use their reasonable endeavors to deliver Natural Gas in accordance with the quality specifications set out in Second Schedule and at the Contract Delivery Pressure referred to in Clause 12.1. However, if at any time or from time to time during the RIP the Natural Gas offered fails to conform with the quality specifications or delivery pressure, a Buyer after using its reasonable endeavors to accept as much of such deficient Natural Gas offered as is possible, may either reject or accept the delivery in whole or in part. In any event, the penalty provisions of Articles XI and XII shall not apply for any quality or pressure deficient gas delivered and Sellers shall not be liable for any other damages during the RIP. 4.3 The Contractual Delivery Date ("CDD") shall occur at the completion of the RIP. 4.4 For each Contract Year there shall be determined, in the manner hereinafter provided, a daily rate for delivery of Natural Gas in that Contract Year which shall be expressed as a quantity of Natural Gas in Cubic Feet and shall hereinafter be called the Daily Contract Quantity ("DCQ"). Each Buyer shall have an individual Daily Contract Quantity ("DCQ*") equal to fifty (50) percent of the DCQ. 4.5 That amount of Natural Gas equivalent to the sum of the DCQs in effect on each Day during the Contract Year shall hereinafter be called the Annual Contract Quantity ("ACQ") and each Buyer shall have an individual Annual Contract Quantity ("ACQ*") which shall be the sum of their DCQs*. 4.6.1 (a) The DCQ at the DCD shall be one hundred and ninety-five (195) MMSCFD and will increase to three hundred and ninety (390) MMSCFD by a date not later than one hundred and eighty (180) Days after the DCD. (b) Such DCQ of three hundred and ninety (390) MMSCFD shall apply and be maintained effective from the date of increase from one hundred and ninety-five (195) MMSCFD to three hundred and ninety (390) MMSCFD pursuant to Sub-clause 4.6.1(a) above for a period of twenty (20) Contract Years. 4.6.2 From the date of the first Field Reserves redetermination described in Article VIII and thereafter, unless revised pursuant to Clause 4.8 or Sub-clause 18.3.1, the DCQ shall not exceed the Field Reserves as last determined pursuant to Article VIII, divided by six thousand (6,000). The Sellers may notify and offer Buyers an increase in the available DCQ if such is supported by a Field Reserves redetermination pursuant to Article VIII and the above maximum limitation of the Field Reserves divided by six thousand (6,000). Buyers may accept all, part or none of such increase pursuant to Sub-clause 4.6.3. 4.6.3 With respect to the proposed increase in DCQ under Sub-clause 4.6.2, the Parties hereby agree that for and in relation to the DCQ to be delivered and sold by Sellers and to be taken and purchased by Buyers for the second and subsequent phases under this Agreement: (a) Sellers' delivery obligations and facility installation shall be based on the Parties' agreed forecast of gas demand realistically expected to occur and from which Natural Gas produced from the Contract Area can be supplied to meet such demand. Such forecast of gas demand shall take into account the relevant delivery and take obligations in Buyers' gas supply contract(s) with their end-users and also, where appropriate, shall take into account any then existing and planned Buyers' facilities expansion. Accordingly, following a Field Reserve determination pursuant to Sub-clause 8.1(i), the Parties shall meet and jointly determine and agree by end of March in each Calendar Year during the term of this Agreement a detailed estimate of daily average gas demand for which the Natural Gas produced from the Contract Area can be supplied to meet such demand for the remaining duration of the term of this Agreement. Where appropriate, such estimate shall also identify any allowance for anticipated market growth and Buyers' new customer(s). The above forecasts and estimates shall be based on market data developed by Buyers (which as such may include Buyers' estimates and forecasts) and shall be established in light of the best market information available taking into account among other things, the accuracy of previous forecasts and rate of actual growth in gas demand and other commercial considerations. The Parties will establish the DCQ(s) and the timing necessary to supply the above forecasts and estimates over the balance of the term of this Agreement. (b) Based on the estimated DCQ(s) established pursuant to paragraph (a) above, the Parties by end of June of the same Calendar Year shall jointly determine and agree on the CDC(s) which shall equal one hundred and ten (110) percent of such DCQ(s) and which shall be the daily obligation of Sellers to supply Natural Gas to Buyers. (c) The Parties shall formalize and execute the documents incorporating the Parties' agreed DCQ and CDC by September 1st of the same Calendar Year. Such DCQ and CDC to be effective on a date mutually agreed by the Parties. 4.7.1 Sellers shall, during the term of this Agreement, maintain the Contractual Delivery Capacity ("CDC") of one hundred and ten (110) percent of the DCQ. Buyers may require Natural Gas from Sellers up to that maximum rate of CDC at any time during the term of this Agreement notwithstanding that the aggregate of such daily requirements may exceed the ACQ. Each Buyer shall have an individual Contractual Delivery Capacity ("CDC*") equal to fifty (50) percent of the CDC. 4.7.2 Notwithstanding the provisions of Clause 4.6 and Sub-clause 4.7.1 but subject to Sub-clause 4.12.1 (b), on each scheduled maintenance Day, as referred to in Sub-clause 4.12.1, Sellers shall deliver and Buyers shall accept delivery of a minimum volume equal to fifty (50) percent of the applicable DCQ, and such minimum volume shall, for that Day, be deemed to constitute and be counted as the CDC for the purpose of determining any Shortfall on Sellers' part and as the deemed DCQ* for the purpose of determining Buyer's or Buyers' Take-or-Pay obligation. 4.8.1 If at any time or from time to time after the fifteenth (15th) Contract Year, part of Sellers' production facilities is damaged by an event beyond the control of Sellers acting in accordance with the standards of a Reasonable and Prudent Operator, and (i) it would be necessary for Sellers to incur any expenditure in order to repair the damage; and (ii) a Reasonable and Prudent Operator would not make such additional expenditure, then Sellers may serve upon each Buyer notice of a decrease in DCQ* which notice shall specify the said decreased DCQ* which shall not be less than that which a Reasonable and Prudent Operator could maintain without making such expenditure. 4.8.2 If within sixty (60) Days following the receipt of such notice under Sub-clause 4.8.1, Buyer or Buyers have informed Sellers that it or they consider(s) the DCQ* or DCQ which a Reasonable and Prudent Operator could maintain without making such additional expenditure as aforesaid is greater than the DCQ* or DCQ specified in the notice, or that a Reasonable and Prudent Operator would make such additional expenditure and the Parties are unable to agree then either Party may require the matter to be submitted for determination to an expert to be appointed under the provisions of Article XX and the expert shall be given access to all material data including raw data available to Sellers. The DCQ or DCQs* determined by the expert shall be the new DCQ or DCQs* in effect. However, in no event shall the new DCQ or DCQs* be greater than the DCQ or DCQs* applicable at the time of the notice as a result of the determination by the expert. 4.9.1 During each Contract Year each Buyer shall purchase and take itsindividual Net Annual Contract Quantity ("Net ACQ*") being the sum of the applicable DCQs* for each Day in the Contract Year multiplied by zero decimal nine zero (0.90) reduced by one half (1/2) of:- (i) any Natural Gas properly notified for delivery on any Day which Sellers have not delivered for any reason other than the failure of Buyers to accept; (ii) any Natural Gas properly notified for delivery on any Day which Buyers have been prevented by Force Majeure from accepting; (iii) any Natural Gas not delivered by reason of construction or tie-in work pursuant to Sub-clause 4.12.1. Each Buyer shall be deemed to have purchased and taken a portion of total Natural Gas delivered in a Contract Year proportional to its DCQ*. 4.9.2 If in a Contract Year a Buyer has not taken at least its Net ACQ*, such Buyer shall pay Sellers the price or prices applicable in that Contract Year for the quantity equal to the difference between the Net ACQ* and the quantity of Natural Gas actually taken(the said Contract Year shall be called a "Debit Year"), and such quantity shall be the Take-or-Pay Gas quantity for that Contract Year. Provided that:- (i) If in any previous Contract Year Buyer has taken and paid for Natural Gas (other than Natural Gas taken in accordance with Sub-clause 4.10.3) in excess of its Net ACQ* for that Contract Year (such excess gas hereinafter being called "Carry Forward Gas"), then such Carry Forward Gas shall be offset against the Take-or-Pay obligation of such Buyer in subsequent Contract Years. (ii) the application of such offset by Carry Forward Gas shall in any Contract Year be limited to fifteen (15) percent of the Net ACQ* for that Contract Year and such Buyer shall pay the remainder, if any, of the Take-or-Pay obligation for that Contract Year. (iii) the balance (if any) of Carry Forward Gas not so used shall be carried forward for offset in subsequent Contract Years, provided however that Carry Forward Gas shall only be used to offset such Buyer's obligations in the five (5) Contract Years following the Contract Year in which the offset was earned. 4.9.3 When under Sub-clause 4.9.2 a Buyer has paid for a quantity of Natural Gas not taken in a Debit Year, such Buyer may in any or all of the subsequent Contract Years take free of charge, after such Buyer has taken the Net ACQ* for that Contract Year, a quantity of Natural Gas up to the quantity of Natural Gas so paid for in respect of the Debit Year or Years. Provided that this Clause shall not oblige Sellers to deliver Natural Gas in excess of the CDC on any Day. 4.10.1 Not later than ten (10) o'clock a.m. each Friday Buyers' Representative, as stipulated in Article XXIV, shall notify Sellers' Representative of the quantity of Natural Gas nominated by Buyers for each Day of the following week. Such quantity shall be delivered at a rate which if sustained throughout the Day will provide not more than the CDC, and so far as reasonably practicable, Sellers shall deliver and each Buyer shall receive at a rate as consistent as possible throughout the Day, with due consideration for the normal fluctuations caused by demand variations and operational control of facilities. 4.10.2 Buyers' Representative may at any time before or during any Day call for the rate of delivery previously notified to be varied to any extent within the limit of Clause 4.7 and Sub-clause 4.9.1 and Sellers shall use reasonable endeavors to comply with such request except that:- (i) Any request for a change of equal to or less than ten (10) percent must be complied with within six (6) hours. (ii) Any request for a change of greater than or equal to ten (10) percent but less than twenty-five (25) percent must be complied with within twelve (12) hours. (iii) Any request for a change of twenty-five (25) percent or greater must be complied with within twenty-four (24) hours. 4.10.3 At the request of Buyers, Sellers shall deliver Natural Gas at a rate exceeding the limits in Sub-clauses 4.7.1 and 4.7.2 if in Sellers' sole judgment they are from a technical point of view reasonably able to do so. 4.10.4 For the purpose of this Agreement, the Natural Gas quantity properly notified for delivery on any Day shall be that quantity which would be tendered for delivery if the delivery rate or rates required by Buyer or Buyers had been sustained throughout the number of hours for which the rate was or the rates were required to be effective. Provided that if Buyers have in fact called for a rate exceeding the applicable CDC, the properly nominated quantity shall be calculated as if the rate called for had been that of the applicable CDC. 4.11 After any event causing a total cessation of Natural Gas deliveries, Sellers, while using reasonable endeavors to meet Buyer's or Buyers' nominations, shall, subject to the provisions of this Agreement, be relieved from the consequences of any failure to deliver the properly nominated quantity in full for a period of twenty-four (24) hours from the time of resumption of deliveries. 4.12.1 (a) For each Year there shall be allocated sufficient time for planned maintenance work of Sellers' production and delivery facilities. The annual maintenance schedule is to be drawn up by Sellers and agreed to by Buyers prior to the start of each Year and such agreement shall not to be unreasonably withheld. Each annual maintenance schedule shall consist of the number of maintenance Days for that Year and the dates planned for the performing of maintenance work, as required by Sellers acting to the standard of a Reasonable and Prudent Operator. (b) It is agreed that Sellers' delivery obligation may, based on prudent operatorship, be reduced to zero (0) percent DCQ provided that:- (i) it shall only be applicable until duplicate production facilities are installed; and (ii) it shall only be for the purpose of Sellers' simultaneous repair and maintenance of their equipment and facilities; and (iii) it shall not exceed a period of forty-eight (48) hours. The Parties recognize that the forty-eight (48) hours is dependent upon the extent and flexibility of Buyers' line-pack and that such period will be shortened if Buyers' line-pack or flexibility is reduced. (c) Following installation of duplicate production facilities, the minimum volume of DCQ to be maintained by Sellers shall not be less than fifty (50) percent of the agreed DCQ. (d) Such minimum volume shall, for that Day, be deemed to constitute and be counted as the CDC for the purpose of determining any Shortfall on Sellers' part and as the deemed DCQ for the purpose of determining a Buyers' Take-or-Pay obligation. (e) Each Day during the maintenance schedule shall be referred to as a "Scheduled Maintenance Day". (f) The maximum allowable maintenance Days for each Year shall be ten (10) Days. Days on which construction or tie-in work required for installation of booster compression, bringing future offshore fields online and other similar operations required from time to time ("Construction Days") shall not be considered as part of the Scheduled Maintenance Days. (g) The Parties may mutually agree to change the maximum allowable maintenance Days, such agreement shall not be unreasonably withheld, as necessary by taking into account amongst others; (i) the condition and age of Sellers' facilities; (ii) any significant changes in production levels; (iii) any significant changes affecting Sellers' production operations; (iv) any maintenance work which may not be necessary on an annual basis but at intervals of more than one Year at a time; and (v) the condition and age of Buyer's or Buyers' facilities and its or their scheduled Maintenance Days as may be required by Buyer or Buyers. 4.12.2 The Parties shall confer on a regular basis and to every reasonable extent possible shall schedule their respective planned maintenance work to coincide on the same Day or Days. For any planned maintenance work that is to be carried out on any dates other than those as planned, the Party wishing to conduct such work shall give the other Party at least five (5) Days written notice in advance of the Day or Days to be utilized for such work. Such Day or Days shall be part of the maximum allowable maintenance Days described in Sub-clause 4.12.1 (f), and not additional thereto. 4.12.3 Based on Sellers' maximum allowable maintenance Days for any Contract Year, Buyer or Buyers may utilize equal time for planned maintenance of its or their gas transmission facilities, gas separation plants and other related facilities. Buyers shall use reasonable endeavours to ensure that their maintenance work coincides with Sellers scheduled maintenance days. 4.12.4 Sellers shall give written notice to Buyers at least one hundred eighty (180) Days prior to Construction Days, and shall as a prudent operator, designate a number of Days in which this work shall be fully performed. At least forty-five (45) Days prior to commencing such work, Sellers shall notify Buyers of the proposed timing and duration of the work. The proposed timing and duration shall have to be agreed by Buyers, such agreement shall not be unreasonably withheld. With such notice Sellers shall indicate a minimum volume, which may be zero (0) percent of the applicable DCQ, for each Construction Day, and such minimum volume shall, for that Day, be deemed to constitute and be counted as the CDC for the purpose of determining any Shortfall on Sellers' part and as the deemed DCQ for the purpose of determining a Buyers' Take-or-Pay obligation. ARTICLE V SELLERS' RESERVATIONS There are reserved to Sellers the following: 5.1 Without prejudice to the nature and extent of the obligations of Sellers under this Agreement the right to decide the manner in which they shall conduct their physical operations. 5.2 The right to use Natural Gas produced by Sellers from the Reservoir for any of the following purposes to the extent that they may be necessary or convenient for the fulfillment of their obligations under this Agreement, including but not limited to: (i) the operation of Sellers' field facilities, process facilities and other miscellaneous uses, including flaring, relating to production from the Reservoir; and (ii) gas lift operations, repressuring, pressure maintenance or cycling operations within the Reservoir. 5.3 The right to process the Natural Gas recovered before delivery to Buyers for the removal of any constituents other than methane, ethane, propane and butane (except such minimum amounts of methane, ethane, propane and butane as would necessarily be removed in the recovery of such constituents). Such removed constituents shall not be a part of this Agreement. 5.4 Any right as may be exercisable by Sellers under this Article V shall not adversely affect Sellers' obligation to deliver and sell Natural Gas to Buyer or Buyers and Buyer's or Buyers' right to take and purchase Natural Gas from Sellers under this Agreement. ARTICLE VI BUYERS' FACILITIES 6.1 Buyers shall provide at their expense such facilities as may be necessary to connect Sellers' nominated platform(s) or other related facilities to Buyers' gas transmission pipelines, gas separation plant and such other downstream facilities as may be necessary to enable Buyers to transmit and dispose of the Natural Gas on and after the DCD at the rate or rates calculated as herein provided. 6.2 Sellers will arrange to make space available on the portion of their Production Platform(s) or other related facilities that faces the Buyers' sealine for the installation and operation of Buyers' gas transmission pipelines and such other facilities, and Buyers agree to compensate Sellers for any proper cost as may reasonably be incurred by Sellers thereby. Any specific arrangements for Buyers' facilities tie-ins shall be the subject of a separate utilization agreement between the Parties.

The Parties agree that each Buyer or Buyers or its/their employees, agents or representatives may enter upon any facilities owned or installed by Sellers pursuant to this Article XIII at the sole risk and expense of such Buyer or Buyers. Provided further that each Buyer or the Buyers shall afford to Sellers the same rights of inspection and verification at the sole risk of Sellers in respect of all check measuring and testing equipment installed at its check measurement station by Buyer or Buyers in respect of the Natural Gas delivered hereunder. 13.2.1 Each component of the measuring and testing equipment shall be adjusted to operate accurately within a limit prescribed by the manufacturer but which shall not in any case exceed a limit of one (1) percent. 13.2.2 The accuracy of Sellers' Equipment shall be verified by Sellers once in every Month during the Contract Period or at such other frequency as may be agreed (and at other times if so required by either Party) and Sellers shall give to Buyers' Representative sufficient prior notice of the date, time and nature of every verification to enable a representative of each Buyer or Buyers to be present. The results of any verification shall be binding on the Parties unless either Buyer or Buyers shall within seven (7) Days after such verification give notice to Sellers that it or they dispute(s) the accuracy of such verification. 13.2.3 Verifications shall be made at the expense of Sellers but each Buyer or Buyers shall bear the cost of the attendance of its representatives at any verification and shall bear the whole expense of any verification made at its request if the accuracy of the equipment concerned is found to be within the limits mentioned in Sub-clause 13.2.1. 13.3 If, at any time or from time to time during the continuance of this Agreement, any component of Sellers' Equipment is found to be out of service or registering outside the limits of accuracy agreed under Sub-clause 13.2.1, Sellers shall forthwith adjust it to read accurately within the limits mentioned in Sub-clause 13.2.1 or (if that is not possible) replace it with a serviceable component and (unless Sellers and Buyer or Buyers shall otherwise agree) the following provisions shall apply with regard to earlier readings affected by the defective component. (i) No correction shall be made in respect of readings made during the period before the period immediately preceding verification of the defective component; (ii) If the time at which the component became defective can be established, then readings affected thereby shall be corrected with effect from that time in the manner provided by paragraphs (a), (b), and (c) of Sub-clause 13.3 (iii); (iii) If the time at which the component became defective cannot be established, then the time which has elapsed since the immediately preceding verification shall be divided into two (2) equal parts and estimated readings shall be established in respect of the first such part by assuming that the defective component has operated accurately throughout such part and in respect of the second such part: (a) by using the readings recorded by any check measuring or testing equipment if such equipment shall be registering accurately within the limits mentioned in Sub-clause 13.2.1; or (b) if such equipment shall not be registering accurately or if no such equipment shall have been installed; by correcting the error if the percentage of error is ascertainable to the satisfaction of both Parties by calibration test or mathematical calculation; or (c) if the percentage of error is not so ascertainable; by estimating the quantity and/or quality of Natural Gas delivered by reference to deliveries under similar conditions when the defective component was registering accurately. 13.4 The Parties shall meet to discuss and to endeavor to settle any dispute which may arise with regard to the application of the provisions of this Article XIII or the measurement of the quantity of Natural Gas delivered and if within thirty (30) Days after the commencement of such meeting they shall have been unable to agree, the matter shall then be referred to an expert to be appointed under the provisions of Article XX. ARTICLE XIV POINT OF DELIVERY, TITLE AND RISK 14.1 Natural Gas to be delivered under the terms of this Agreement shall be delivered by Sellers to each Buyer at the Delivery Point(s) specified in the Fourth Schedule attached hereto. Should future development require additional Delivery Point(s) both Parties shall meet in good faith with the view to agreeing on such additional Delivery Point(s). 14.2 The title and risk in the Natural Gas delivered by Sellers shall pass to Buyers at the Delivery Point(s). Provided that, if any Natural Gas so delivered is deficient in quality at the moment of its passage through a Delivery Point, regardless of Buyer's knowledge of such quality deficiency, such Natural Gas, for the purposes of this Agreement, shall be deemed to have been delivered and Buyers may recoup from Sellers for any damages incurred by Buyers in consequence of such deficiency up to a monetary amount equal to the value of a volume of Natural Gas that would be delivered in six (6) Days at the DCQ and Contract Price in force adjusted by the weighted average Gross Calorific Value for the Natural Gas delivered during the preceding twelve (12) Months by reducing the price of Natural Gas to be delivered thereafter by twenty (20) percent until such cost is repaid which recoupment shall be in place of any other rights and remedies of each Buyer. 14.3 As soon as reasonably practicable upon notification by Buyers' Representative of the occurrence of a breakage of a sealine causing an escape of Natural Gas, Sellers shall stop delivering Natural Gas and Buyer or Buyers shall not be required to pay for any Natural Gas passing the respective Delivery Point(s) after such breakage has been notified, provided that Buyer or Buyers shall, in good faith, promptly and diligently repair such breakage. ARTICLE XV DEFAULT 15.1 Except as otherwise provided in this Article XV and Clauses 11.2 and 12.2, each Party shall be liable to the other in the event of such Party's default or breach of an obligation hereunder only for actual costs, expenses and damages incurred by such other Party as the direct result of such default or breach. 15.2 Except as otherwise provided under Clause 15.3, if, after the CDD, Sellers fail to deliver on any Day the quantity, or any portion thereof, of the Natural Gas properly notified by Buyers' Representative for delivery on that Day (the deficient quantity being termed "Shortfall"), Buyer's remedy shall be the right to take as soon as possible as part of the Net ACQ in the following Month (or Months if required) a quantity of Natural Gas equal to the quantity of Shortfall at a reduced price equal to seventy-five (75) percent of the Contract Price applicable at the time the Shortfall occurred. Whenever this Clause 15.2 is applicable, the rights provided herein shall be in place of any and all other rights and remedies, including any right to damages, that Buyer or Buyers might otherwise have been entitled to. 15.3 Regardless of whether or not Clause 15.2 is applicable, Sellers shall not be liable to either Buyer for failure to deliver the quantity of Natural Gas properly notified for any Day: (i) If Sellers have been prevented by Force Majeure from delivering such Natural Gas; or (ii) If Buyer or Buyers have failed to accept delivery of such Natural Gas (unless the Buyer or Buyers have properly refused to accept delivery under Article XI or Article XII). 15.4 The maximum liability of any Buyer in respect of non-fulfilment of its obligations to take Natural Gas hereunder shall be limited to its liability to pay for gas not taken pursuant to Sub-clause 4.9.2 subject always to Buyer's rights under Sub-clauses 4.9.3 and 18.3.1. 15.5 In no event shall either Party be liable to the other for indirect or special damages of any kind nor shall either Party be liable to the other for damages asserted or claimed to have been suffered by any third party who is not a Party to this Agreement. ARTICLE XVI FORCE MAJEURE 16.1 In this Agreement, the term "Force Majeure" means any happening, event or its pernicious results which are beyond the control of a Party acting as a Reasonable and Prudent Operator, which causes or results in a failure by such Party to fulfil any obligation (other than obligations to give a notice or to pay money to another or others of the Parties) under this Agreement. 16.2 Events which may be subject to Clause 16.1 and considered as Force Majeure events shall include, but not be limited to, acts of government, strikes, lock-outs, acts of the public enemy, wars whether declared or undeclared, blockades, insurrection, riots, epidemics, landslides, lightning, earthquakes, fires, storms, floods, washouts, civil disturbances, protests of the public which obstruct or cause any delay in the construction of the Pipeline System as defined in Article 4.2.1 (b), explosions, partial or entire failure, breakage or accident to the facilities used or required to deliver and receive Natural Gas including machinery, pipelines, Natural Gas Separation plants, and related facilities, inability to obtain environmental approvals and permits and EIA Approval necessary for the installation of the Pipeline System from the Office of Environmental Policy and Planning of Thailand and/or other relevant government authorities thereof by September 30, 2000, freezing of wells or pipelines, partial or entire failure of wells, inability to obtain necessary materials or supplies due to changes in laws and regulations, material changes in the obligations of Sellers under the PSC, as may be imposed by the Government of Thailand or the Government of Malaysia, or the inability of any customer or customers of Buyer or Buyers to take Natural Gas which it or they would have taken if such inability is caused by a happening which would have constituted Force Majeure under Clause 16.1 as if the customer or customers concerned had been a Party to this Agreement, provided that the customer or customers claiming Force Majeure is or are capable of accepting gas deliveries from the pipeline system connected to the Contract Area. Provided that a Buyer shall have no right to Force Majeure relief hereunder by reason of the inability of any of its customers to take Natural Gas unless Buyer shall pro-rate the amount of relief which it requires among all of its relevant suppliers. Buyer shall quantify the pro-rated reduction in production it requires from its relevant suppliers by making the following calculation: the deemed amount of Natural Gas which would have been delivered to the customer concerned calculated by reference to the average delivery to that customer over the immediately preceding ninety (90) Days or such lesser period if data from ninety (90) Days deliveries are not available divided by Buyer's receipts from all of its relevant Natural Gas suppliers based on the average take of Natural Gas from each relevant supplier over the same ninety (90) Days or lesser period. 16.3 A Party claiming relief on account of Force Majeure shall: (i) as soon as practicable give notice to the other Party or Parties of the happening said to constitute Force Majeure. Such notice shall include full information about the circumstances and a statement of the steps and time believed necessary to remedy the failure but neither Party shall be obliged to settle or prevent any strike or other industrial action except on terms acceptable to it. (ii) subject to Article XVIII and Sub-clause 4.8.1 proceed as a Reasonable and Prudent Operator at its own expense to remedy the failure with all reasonable dispatch. 16.4 A Party failing to fulfil its obligations (other than the obligations to give notice or to pay money excepted under Clause 16.1) by reason of Force Majeure and fulfilling the requirements of Clause 16.3 shall be relieved of its obligations under this Agreement, so far as they are affected by such Force Majeure during the continuance of any inability so caused, including without limitation, liability as follows: (a) in the case of Sellers to the extent that Force Majeure has prevented them from delivering Natural Gas that they should have delivered. (b) in the case of Buyer or Buyers to the extent that Force Majeure has prevented them or their customers (subject to the proviso of Clause 16.2) from accepting Natural Gas which they should have accepted or from disposing of the same. ARTICLE XVII TERM OF AGREEMENT The term of this Agreement shall begin on the Effective Date, and shall so continue in force subject to the provisions of Article XVIII, for the duration remaining in the PSC, or any extension to the PSC unless otherwise mutually agreed by the Parties. Rights and obligations accrued to and incurred by each Party prior to termination of this Agreement shall survive such termination. ARTICLE XVIII TERMINATION 18.1 Notwithstanding the provision of Article XVII, this Agreement shall terminate upon the first occurrence of either of the following: (i) There is no longer a positive balance of Field Reserves remaining in the Reservoir. If this Agreement terminates because there is no longer a positive balance of Field Reserves remaining in the Reservoir, then Sellers shall reimburse to each Buyer the net amount which each Buyer has paid for gas pursuant to Sub-clause 4.9.2 but not taken pursuant to Sub-clause 4.9.3. Reimbursement shall be made within thirty (30) Days of termination, after which interest shall be paid in accordance with Clause 10.7 until payment is effected; or (ii) Upon the termination of the PSC or any extension to the PSC. 18.2 Sellers shall in good faith endeavor to give to Buyers not less than two (2) Years notice in advance of the date upon which the termination event is expected to occur but this Agreement shall terminate when such event occurs whether before or after the date notified by Sellers. 18.3.1 If at any time after Sellers have served a notice of a decrease in DCQ* under Sub-clause 4.8.1, the sealine connecting the Production Platform with the shore or any other part of the facilities necessary for the transmission, compression, treatment or distribution of the Natural Gas which is the subject of this Agreement is damaged by a happening beyond the control of Buyer or Buyers acting in accordance with the standards of a Reasonable and Prudent Operator and (i) it would be necessary for Buyer or Buyers to incur an expenditure in order to repair the damage; and (ii) a Reasonable and Prudent Operator would not make such additional expenditure, then Buyer or Buyers, subject to the determination of an expert as appointed in Sub-clause 18.3.2 below, may reduce their DCQ* or terminate this Agreement, as appropriate to the extent of the damage, with immediate effect and if this Agreement is so terminated then Buyer or Buyers and Sellers shall be excused from all obligations thereafter. 18.3.2 If within sixty (60) Days following the receipt of such notice under Sub-clause 18.3.1, Sellers have informed Buyer or Buyers that Sellers consider that a Reasonable and Prudent Operator would make such additional expenditure and the Parties are unable to agree then either Party may require the matter to be submitted to an expert to be appointed under the provisions of Article XX and the expert shall be given access to all material data including raw data available to Buyer or Buyers. 18.4 Termination under this Article XVIII shall not relieve any Party of an obligation to pay amounts due and payable to another at the time of termination. 18.5 If any provision or part of this Agreement is void, this Agreement as a whole shall not be effected thereby, and, if practicable, the remainder of the provisions hereof shall remain valid and enforceable. Provided, however, that if such affected provision is considered as essential by any Party, the Parties shall meet and endeavour in good faith to set out a legal replacement provision. ARTICLE XIX ASSIGNMENT 19.1 No Party shall be entitled to assign any of its rights or obligations under this Agreement to a third party without the written consent of the other Parties. Such consent shall not be unreasonably withheld. ARTICLE XX EXPERTS 20.1 The provisions of this Article XX shall apply whenever in this Agreement it is provided that any person is to be appointed an expert, or that any matter is to be referred to an expert, or whenever during the term of this Agreement the Parties agree that a point of difference between them shall be resolved by an expert. 20.2 The procedure for the appointment of an expert shall be the following: 20.2.1 The Party wishing the appointment of an expert to be made shall give notice in writing to that effect to the other Parties and in such notice shall give details of the matter which is proposed to be resolved by the expert. 20.2.2 The Parties shall meet in an endeavor to agree upon a single expert to whom the matter in dispute shall be referred to for determination. 20.2.3 If within twenty-one (21) Days from the service of the said notice, the Parties have either failed to meet or failed to agree upon an expert, then the matter shall forthwith be referred by the Party wishing the appointment to be made, to the President of the International Gas Union who shall be requested to make the appointment of the said expert within thirty (30) Days and may in so doing take such independent advice as he thinks fit.

Acceptance of appointment shall be notified within twenty-four (24) hours to the other Parties. 20.2.5 If such expert shall be either unwilling or unable to accept such appointment or shall not have accepted within the said fourteen (14) Days then unless the Parties are able to agree on the appointment of another expert who is willing and able to act, the matter shall again be referred to the President of the International Gas Union who shall be requested to make a further appointment and if not, then to the I.C.C. for a further appointment, and the process shall be repeated until an expert who accepts the appointment is found. 20.3.1 No person shall be appointed to act as the expert under this Article XX unless he shall be qualified by education, experience and training to determine the matter in dispute, and shall have an international reputation or expertise in the area of dispute. 20.3.2 No person shall be appointed an expert who at the time of appointment is an employee, former employee, or any person engaged as a consultant by either Party, or if such expert has any interest or duty which conflicts with the duties and functions of the expert for the purpose of the appointment pursuant to this Agreement. Further, the expert may be removed if he has or acquires at any time before rendering his decision an interest or duty which conflicts with the duties and functions of the expert for the purposes of any decision under this Agreement. 20.4.1 The expert appointed shall make his decision on data, information and submissions supplied to him by the Parties not later than thirty (30) Days after his acceptance of the appointment and shall ignore data, information and submissions supplied and made after such thirty (30) Days unless the same are furnished in response to a specific request from him. The Parties shall cooperate with the expert to the fullest extent. The expert shall be provided access to data and information, which the Parties are able to make available and which in the judgement of the expert might aid him in making a valid determination. Representatives of the Parties shall have the right to consult with the expert and to furnish him written materials, but the expert may impose reasonable limitations on this right and shall be free to evaluate the extent to which any data or information is substantiated or pertinent. 20.4.2 If within a reasonable period which shall not in the case of a redetermination under Article VIII exceed one hundred and eighty (180) Days or in any other case ninety (90) Days after the acceptance by an expert of the appointment such expert shall not have rendered a decision, declines to act, dies or otherwise becomes unable to act as expert hereunder, then at the request of either Party a new expert shall be appointed under the provisions of this Article XX and upon the acceptance of appointment by such new expert the appointment of the previous expert shall cease. Provided that if the previous expert shall have rendered a decision prior to the date upon which the new expert accepts his appointment then such decision shall be binding upon the Parties and the instructions to the new expert shall be withdrawn. 20.5 The said expert shall be deemed not to be an arbitrator but shall render his decision as an expert. The report of the expert shall be in writing and shall set forth his decision and reasons therefore. 20.6 The decision of the expert shall be final and binding upon the Parties save in the event of fraud, mistake or failure by the expert to disclose any relevant conflict of interest. A Party acting in compliance with a decision of the expert shall not be liable for loss or damage suffered by the other Party resulting from acts or omissions committed by the first mentioned Party which are necessary for compliance with the expert's decision. 20.7 Each Party shall bear the costs and expenses of all counsel, witnesses, and employees retained by it but the costs and expenses of the expert shall be apportioned equally between Sellers and Buyer or Buyers. ARTICLE XXI ARBITRATION 21.1 Any and all disputes between the Parties arising out of or in connection with this Agreement, including its negotiation, execution, interpretation, performance or non-performance which they are not by this Agreement required or entitled to refer for determination to an expert appointed under the provisions of Article XX shall be solely and finally settled by arbitration in accordance with the procedures and rules of UNCITRAL and as set out below. Each Party agrees not to institute any lawsuit in respect of any dispute falling within the foregoing agreement to arbitrate except to enforce this Agreement to arbitrate or to enforce the award of the arbitrators . 21.2 If either Party refers a dispute to arbitration, each Party shall appoint one arbitrator and such arbitrators in turn shall jointly appoint a third arbitrator. 21.3 Each Party shall inform the other Party of the name of its own arbitrator within sixty (60) Days from the date on which either Party referred the dispute to arbitration; and if any Party fails to do so within the prescribed time, the other Party may request the President of the International Bank for Reconstruction and Development (hereinafter called "World Bank") to appoint an arbitrator for the first Party. 21.4 The arbitrators shall appoint the third arbitrator within sixty (60) Days from the date on which both arbitrators have been appointed; and if the arbitrators fail to do so or fail to agree on the appointment of the third arbitrator within the prescribed time, either Party or both Parties may request the President of the World Bank to appoint the third arbitrator for them. 21.5 If the President of the World Bank fails to appoint an arbitrator in accordance with Clause 21.3 or 21.4 within sixty (60) Days from the date of request thereunder, then either Party or both Parties may request the International Chamber of Commerce to make the appointment. 21.6 If for any reason whatsoever the appointment of an arbitrator is not made or a vacancy is not filled in accordance with Clause 21.5, either Party may request the President of the Federal Tribunal of Switzerland to make the relevant appointment. 21.7 The expenses of the arbitrator of either Party, whether or not appointed by that Party, shall be advanced by that Party. The expenses of the third arbitrator shall be advanced equally by both Parties. 21.8 The place of arbitration shall be as agreed upon by the Parties or, in the absence of an agreement, shall be Singapore. The language for the arbitration shall be English. 21.9 The procedure shall be that of the UNCITRAL Arbitration Rules. 21.10 In rendering an award, the arbitrators shall take into account the general principles of international laws as may be applicable, and any generally accepted customs and usages of the international petroleum business and shall determine in the award the expenses and fees of the arbitrators to be borne solely by either Party or to be shared by both Parties in such proportion as may be deemed proper. 21.11 The award of the arbitrators shall be final and binding on both Parties. Should any Party fail to comply with such award or if no settlement shall be obtained through arbitration then and only then the Parties shall submit the dispute to a court of competent jurisdiction. ARTICLE XXII WAIVER No waiver by either Party of any default or defaults by the other in the performance of any of the provisions of this Agreement shall operate or be construed as a waiver of any other or further default or defaults whether of a like or different character.

THIRD SCHEDULE MEASUREMENT OF NATURAL GAS DELIVERED 1. METERING The Natural Gas delivered under this Agreement shall be measured with meters constructed and installed, and whose computations of volume are made, in accordance with the provisions of Gas Measurement Committee Report No. 3 of the American Gas Association (AGA) as reprinted and revised September, 1985, with any subsequent amendments or revisions which may be mutually acceptable to both Parties. 2. ADJUSTMENT FOR SUPERCOMPRESSIBILITY Adjustment for the effect of supercompressibility shall be made according to the provisions of AGA Report No. 3 herein, above identified, for the average conditions of pressure, flowing temperature and specific gravity at which the gas was measured during the period under consideration and with the proportionate values of each, carbon dioxide and nitrogen, in the gas delivered included in the computation of the applicable supercompressibility factors. Sellers agree to exercise due diligence in obtaining initial carbon dioxide and nitrogen fraction values and to obtain subsequent values of these components as may be required from time to time. Sellers shall use the AGA analysis method to calculate the applicable supercompressibility factors for gas with diluent content (carbon dioxide or nitrogen) greater than fifteen (15) mol. percent. 3. TEMPERATURE The temperature of the gas shall be determined by a recording thermometer so installed that it will record the temperature of the gas flowing through the meters. The recording thermometer shall be installed and maintained by Sellers in accordance with the specifications set forth in said AGA Gas Measurement Committee Report No. 3. The arithmetical average of readings each Day shall be deemed the gas temperature and used in computing the volume of gas metered during such day. 4. SPECIFIC GRAVITY Tests to determine the specific gravity of the gas being metered shall be made by Sellers in accordance with ASTM (American Society for Testing and Materials) Standard D1070-85 "Standard Test Methods for Relative Density of Gaseous Fuels", or any subsequent revision thereof acceptable to both Parties. In lieu of the use of ASTM Standard D1070-85, the Parties may agree to determine the specific gravity of the gas in accordance with the calculations set forth in said AGA Gas Measurement Committee Report No. 3. The gas samples to be tested shall be representative of the gas being metered at the time such samples are taken and may be either spot samples or samples taken over a period of time. Samples shall be taken at reasonable intervals by Sellers, provided that Sellers shall take additional samples when requested by Buyer or Buyers to do so. The specific gravity determined by any test shall apply to the gas metered from the date the spot sample was taken or from the commencement date of a sample taken over a period of time, as the case may be, until the next test. Either Party to this Agreement can elect to have the specific gravity of the gas determined by the continuous use of a recording gravitometer of standard make, acceptable to both Parties, in accordance with ASTM Standard D1070-85. The recording gravitometer will be installed and maintained by Sellers. The arithmetic average of the specific gravity recorded each twenty-four (24) hour Day or part thereof during which gas shall have been delivered shall be used in computing gas volumes for that date. 5. HEATING VALUE DETERMINATION The Gross Calorific Value of the Natural Gas in BTU's per Cubic Foot shall be determined by Sellers from gas samples taken with a continuous sampler. Tests to determine the calorific value of gas delivered shall be made by utilizing a recording calorimeter operated and maintained in accordance with ASTM (American Society for Testing and Materials) Standard D1826-88 "Standard Test Method for Calorific Heating Value of Gases in Natural Gas Range by Continuous Recording Calorimeter", or any subsequent revision thereof acceptable to both Parties. The Parties to this Agreement may agree to determine the calorific value of gas delivered in accordance with the calculation set forth in said AGA Gas Measurement Committee Report No. 3. The Gross Calorific Value determined by any test shall apply to the gas metered from the commencement date of the sample until the next sample is taken for test.
