W I T N E S S E T H WHEREAS, the Petroleum Authority of Thailand ("PTT") and Thaipo Limited, Thai Romo Limited and The Sophonpanich Co., Ltd. have entered into that certain Gas Sales Agreement dated November 7, 1995 (the "Gas Sales Agreement") in connection with the Petroleum Concession Agreement No. 1/2534/36, dated August 1, 1991, covering block B8/32 offshore Thailand, awarded by the Ministry of Industry to Maersk Oil (Thailand) Ltd., Thaipo, Limited and Thai Romo, Limited, and Supplementary Petroleum Concession No. 1 to Petroleum Concession No. 1/2534/36, dated March 6, 1992, whereby The Sophonpanich Co., Ltd., entered into Petroleum Concession No. 1/2534/36 (collectively, the "Concession Agreement"); WHEREAS Thaipo Limited, Thai Romo Limited and Palang Sophon Limited (formerly known as Sophon Thai Gulf Limited which was successor in interest to The Sophonpanich Co. Ltd.) are currently the Concessionaires under the Concession Agreement (collectively "the Concessionaires"); WHEREAS, Charterer desires to charter from Lessor on a bareboat basis a Floating Production Storage and Offloading System known as the "Tantawan Explorer" (the "FPSO"), for use in the Tantawan Field, Thailand; NOW, THEREFORE, in consideration of the mutual covenants herein contained, Lessor and Charterer agree as follows: 1. TRANSPORTATION, INSTALLATION AND COMMISSIONING OF THE FPSO Lessor shall be responsible for delivery (the "Delivery") of the FPSO to Charterer in international waters offshore the yard at which the FPSO is being converted (the "Delivery Site") as evidenced by a certificate of delivery issued by Lessor and countersigned by Charterer. Prior to Delivery, Lessor shall be fully responsible for and assume all risks with respect to the FPSO. Charterer has hired an operator ("Operator") pursuant to an Operating Agreement (the "Operating Agreement") to operate the FPSO commencing with Delivery. Operator shall be responsible for completing all work to be performed in respect of the FPSO until Field Acceptance, as herein defined, has occurred, including transporting the FPSO from the Delivery Site to the site in the Tantawan Field designated by Charterer (the "Offshore Site"), hooking-up the FPSO on its anchoring system and hydrostatic, electrical and instrumentation testing. Operator shall also be responsible for commissioning the FPSO. 2. FPSO TO BE CHARTERED Charterer hereby agrees to bareboat charter the FPSO as described in APPENDIX A and its inventory from Lessor, for the period and upon the terms and conditions stated herein. Lessor represents, undertakes and warrants that at the time of Delivery the FPSO shall comply with the requirements of the design basis set forth in APPENDIX A hereto (the "Design Basis") and shall be properly documented and classed as ABS A1 Floating Production, Storage and Offloading System, with no recommendations and as per the particulars of APPENDIX A. Lessor shall before and at the time of Delivery make the FPSO seaworthy and in every respect ready in hull, machinery and equipment for service hereunder. 1 3. SERVICE Charterer shall have the full use of the FPSO at the Offshore Site and, subject to Lessor's approval, at any other place in the world where its operation is not prohibited by applicable law and/or regulations. Charterer may subcontract to identified subcontractors certain of its obligations hereunder, including, but not limited to, those relating to the operation, maintenance and repair of the FPSO. However, such subcontracts shall not relieve Charterer of such obligations. 4. DURATION OF CHARTER 4.1 The term (the "Initial Term") of this Agreement shall commence upon Delivery. The Initial Term shall end upon a date eleven (11) years and six (6) months after Hire Commencement Date (as defined in Article 9.1). 4.2 When the FPSO is hooked up at the Offshore Site and is ready to receive hydrocarbons, when hydrostatic tests have been satisfactorily completed and, to the extent possible, when electrical and instrumentation tests have been satisfactorily completed, Charterer or its nominee will make an inspection to determine whether such events have occurred. Within twenty-four (24) hours of the inspection, Charterer will notify Lessor in writing of whether or not such events have occurred. Lessor will cause Operator to have available at the Offshore Site appropriate and experienced staff to promptly correct all items found to be unacceptable. When Charterer is satisfied that such events have occurred ("Field Acceptance"), Charterer shall sign a certificate of field acceptance to this effect. (If Charterer's affiliate shall fail to perform or cause to be performed the work of installing pipeline end manifolds ("PLEMs") and the anchoring of the mooring system for the FPSO at the Offshore Site and such failure shall have directly and solely prevented the occurrence of Field Acceptance, then Field Acceptance shall be deemed to have occurred as of the date Field Acceptance would have occurred but for Charterer's actions or failure to perform such action.) Field Acceptance by Charterer shall not be construed as a waiver or discharge of any of the representations, warranties or undertakings of Lessor in or with respect to this Agreement or the FPSO. 4.3 Upon the expiration of the Initial Term, Charterer shall have the option to terminate this Agreement, extend this Agreement on an annual basis at prices to be agreed upon by Lessor and Charterer, or purchase the FPSO pursuant to Article 23. The election of any such option may be exercised by Charterer's giving Lessor notice thereof at least 360 days prior to the expiration of the Initial Term. If no such notice is received, Charterer shall be deemed to have exercised its option to terminate this Agreement as of the end of the Initial Term. If Charterer elects to extend this Agreement, then Charterer and Lessor shall negotiate in good faith in an effort to reach agreement prior to the end of the Initial Term on a Total Bareboat Rate for the subsequent annual term. If no such agreement is reached, Charterer shall have the additional option to purchase the FPSO as aforesaid by notice to Lessor at least 180 days prior to the end of the Initial Term. If no agreement on a Total Bareboat Rate for an extended term is timely reached and if no notice of an election to purchase the FPSO is timely given, Charterer shall be deemed to have exercised its option to terminate this Agreement as of the end of the Initial Term. If an agreement on Total Bareboat Rate for an extended term is reached, this Agreement shall be extended until the first anniversary date of the end of the Initial Term and this Article 4.3 shall apply at the end of said extended term MUTATIS MUTANDIS. 5. GUARANTEES 5.1 Simultaneously with the execution of this Agreement, Charterer shall furnish to Lessor several guarantees limited to field percentage interest (the "Joint Venturer Guarantees") of Charterer's performance under this Agreement which shall be given by Thaipo Limited, Thai Romo Limited and Sophon Thai Gulf Limited (the "Joint Venturers") in the form of APPENDIX B-1 hereto. 2 5.2 As security for payment of Hire (as hereinafter defined) and other amounts due to Lessor hereunder, Charterer shall grant or cause the Concessionaires to grant (to the extent permitted by Thai law) a security interest to Lessor in all oil produced from the Tantawan Field taken on board the FPSO and the proceeds thereof, such security interest to be subordinate to royalties, taxes and field operating expenses and granted on a PARI PASSU basis, with all lenders financing the development of the Tantawan Field. Charterer shall fully assist Lessor in perfecting such a security interest, to the extent permitted by the laws of the United States of America and the laws of Thailand. Charterer shall not agree to permit such other lenders to perfect their security interests if Lessor is unable or elects not to perfect its security interest. 5.3 Lessor has delivered to Charterer a Guarantee and Indemnity Agreement ("Lessor Parent Company Guarantee") in the form of APPENDIX B-2 hereto, executed by its ultimate corporate parent, IHC Caland N.V., guaranteeing the performance by Lessor of its obligations hereunder. 6. REPRESENTATIONS AND WARRANTIES 6.1 Lessor represents and warrants to Charterer that: a) Lessor is a corporation duly organized and in good standing under the laws of the Netherlands; has all requisite corporate power and all material governmental licenses, authorizations, consents and approvals necessary to own its assets and carry on its business as now being or as proposed to be conducted;

has all requisite corporate power and all material governmental licenses, authorizations, consents and approvals necessary to own its assets and carry on its business as now being or as proposed to be conducted;

the execution, delivery and performance by Charterer of this Agreement has been duly authorized by all necessary corporate action on its part; and this Agreement has been duly and validly executed and delivered by Charterer and constitutes its legal, valid and binding obligation, enforceable against Charterer in accordance with its terms except to the extent such enforceability may be limited by (i) bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability affecting the enforcement of creditor's rights and (ii) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). c) The execution and delivery of this Agreement and the consummation of the transactions herein contemplated will not conflict with or result in a breach of the certificate of incorporation or by-laws of Charterer or any applicable law or regulation or any material agreement or instrument to which Charterer is a party or by which it is bound or to which it is subject or constitute a default under any such material agreement or instrument. d) All authorizations, approvals and consents of, and filings or registrations with, any governmental or regulatory authority or agency, as are at the date of Delivery necessary for the execution, delivery or performance by Charterer of this Agreement and for the legality, validity, or enforceability hereof, will have been obtained at such date and thereafter will be maintained until the expiration or termination of this Agreement. e) Charterer will not, for the duration of the charter term, engage in significant activities or own substantial assets located in the United States of America. 6.3 OTHER THAN AS SPECIFICALLY STATED IN THIS AGREEMENT NEITHER PARTY SHALL BE DEEMED TO HAVE MADE ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, AS TO THE TITLE, SEAWORTHINESS, MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE OR USE OF THE FPSO OR ANY PART THEREOF. 7. MAINTENANCE AND OPERATION 7.1 Lessor agrees that the FPSO shall, for the duration of the charter term, be in the full possession and at the absolute disposal for all purposes of Charterer and under its complete control in every respect. Subject to Article 7.3, as necessary to meet and maintain requirements of the American Bureau of Shipping ("ABS"), Charterer shall maintain the FPSO in a good state of repair. In addition, Charterer shall maintain the FPSO in efficient operating condition and in accordance with good commercial maintenance practice, and shall keep the FPSO with valid, unexpired classification of the class as indicated in Article 2, free of recommendations and notations affecting class. Charterer shall furnish Lessor with one duplicate original or certified true copy of all class and flag certificates issued or notated during the duration of the charter upon their issuance or notation. Lessor shall keep all Thai, Bahamian (the "Country of Registry") and other required certificates valid, up-to-date and in full force at all times. Charterer shall maintain the following maintenance reports, records, surveys and documents: Planned Maintenance System, Continuous Survey of Machinery and such other reports, records, surveys and documents as Lessor shall reasonably specify in writing. Charterer shall provide copies of such documents to Lessor upon Lessor's request. Lessor shall provide Charterer and Operator with all authorizations which Charterer may reasonably require in order to accomplish the actions required or permitted to Charterer under this Article 7. 4 7.2 Subject to Article 7.3, Charterer shall take immediate steps to have all necessary repairs done within a reasonable time. 7.3 Notwithstanding the terms of Articles 7.1 and 7.2, Major Repairs necessary to meet and maintain ABS requirements and the Design Basis shall be the responsibility of Lessor provided always that Charterer has not caused the need for such repairs as a result of Charterer's gross negligence or willful misconduct. "Major Repairs" shall mean all repairs to the FPSO other than: (a) repairs resulting from corrosion caused by a combination of carbon dioxide and water in the gas stream, and (b) repairs costing less than U.S. $100,000 per incident. Such Major Repairs shall be carried out by Lessor and Charterer shall provide all necessary assistance. 7.4 In the event of any improvement, structural changes or new equipment becoming necessary for the continued operation of the FPSO by reason of new class requirements or compulsory legislation or in order to maintain the FPSO in compliance with the Design Basis, then Lessor shall carry out such work at its expense. 7.5 Charterer shall establish and maintain financial security of responsibility in respect of oil or other pollution damage as required by any government or other division or authority thereof, to enable the FPSO, without penalty or charge, lawfully to enter and remain at the Offshore Site in performance of this Agreement or in the case of removal of the FPSO to another site as may be permitted by the terms hereof, at such other site. Charterer shall make and maintain all arrangements by bond or otherwise as may be necessary to satisfy such requirements at Charterer's sole expense. 7.6 Charterer shall at its own expense and by its own procurement, except as stated to the contrary elsewhere, man, victual, operate, supply, fuel and repair the FPSO whenever required during the duration of this Agreement and shall pay all charges and expenses of every kind and nature whatsoever incidental to its use and operation of the FPSO under this Agreement. The Master, officers, crew and production personnel of the FPSO shall be the servants of Charterer for all purposes whatsoever. 7.7 Charterer shall comply with the regulations of the Country of Registry and, to the extent applicable, the Kingdom of Thailand. Charterer will cause the FPSO to comply at all times with all applicable laws, treaties and conventions and with all rules and regulations issued thereunder and to have on board, when required thereby, valid certificates showing compliance therewith. 7.8 During the duration of this Agreement the FPSO shall retain her present name and shall remain under and fly the Bahamian flag, provided, however, that Charterer shall have the liberty to paint the FPSO in its own colors, install and display its funnel insignia and fly its own house flag. Painting and repainting, installment and re-instalment shall be for Charterer's account. 7.9 (a) Subject to Article 7.4 and Lessor's approval, which shall not be unreasonably withheld, Charterer shall have the right to add additional equipment, modify existing equipment or connect additional production facilities. Any such additions or modifications, including the installation thereof, shall be at the sole cost, risk and expense of Charterer. Such additions, modifications and connections so installed shall, without necessity of further act, become part of the FPSO and the property of Lessor; PROVIDED, HOWEVER, that so long as no Event of Default shall have occurred and be continuing, any such additions, modifications and connections not required to be installed in order to meet the requirements of Article 7.4 hereof and not installed as replacements for property included on board the FPSO on the date of Field Acceptance may be removed (so long as such removal can be accomplished without damage to the FPSO) by Charterer, at its own expense and risk, at any time during, or at the expiration of, the Initial Term upon reasonable prior notice, whereupon such equipment shall, without necessity of further act, become the property of Charterer. 5 (b) Charterer may, in the ordinary course of maintenance, repair or overhaul of the FPSO, remove any item of property constituting a part of the FPSO; PROVIDED, HOWEVER, that such item is replaced as promptly as possible by an item of property which is free and clear of all liens, encumbrances and rights of others and is in as good operating condition, is as seaworthy and has a value and utility at least equal to the item of property being replaced. Any item of property removed from the FPSO as provided in the preceding sentence shall remain the property of Lessor until replaced in accordance with the terms of such sentence, but shall then, without further act, become the property of Charterer. Any such replacement item of property shall, without further act, become the property of Lessor and be deemed part of the FPSO as defined herein for all purposes hereof. 7.10 Charterer shall have the use of all items of inventory, equipment and spares being part of or on board the FPSO on the date of Delivery, which Lessor undertakes to provide. Such inventory will be specified pursuant to Article 14. 8. INSPECTION 8.1 Lessor shall have the right at any reasonable time to inspect or survey the FPSO itself or to instruct a duly authorized third-party surveyor to carry out such survey on its behalf to ascertain the condition of the FPSO, and to satisfy itself that the FPSO is being properly repaired, maintained and operated. Such inspections and surveys shall be for Lessor's account. Charterer shall provide, free of charge to Lessor, upon reasonable request by Lessor, transportation from the shore base to the FPSO and vice versa on its regular flights and, to the extent available, accommodations, catering and communication on board for such inspectors or surveyors. 8.2 Charterer shall also permit Lessor to inspect the FPSO's log books whenever requested and shall immediately furnish Lessor with full information regarding any casualties or other accidents or damage to or caused by the FPSO. 9. COMPENSATION 9.1 As full compensation for the performance by Lessor of its obligations under this Agreement, Charterer shall pay Lessor a hire ("Hire"). Hire shall accrue in accordance with this Article 9 commencing at 0001 hours local time at the Offshore Site on the date ("Hire Commencement Date") on which both (a) Field Acceptance, and (b) the earlier of (i) December 20, 1996 or (ii) the date on which hydrocarbons begin flowing through the FPSO, shall have occurred. Except as otherwise provided herein, Hire shall continue to accrue until the date when the FPSO is redelivered to Lessor under the terms of this Agreement. Hire for the first ten (10) years after the Hire Commencement Date shall be paid at the rate of $65,752 per day, and Hire for the final eighteen (18) months of the Initial Term shall be paid at the rate of $43,227 per day (as applicable, the "Total Bareboat Rate") in the manner provided for in Article 24, subject to adjustment by mutual agreement of the parties, and, except as otherwise specifically provided herein, no other compensation or reimbursement shall be due to Lessor for the performance of its obligations hereunder. 9.2 Payment of Hire shall be made monthly in arrears, without any discount, adjustment, set off or deduction, except as specifically set forth in this Article 9 or otherwise in this Agreement. Lessor shall provide invoices to Charterer covering each payment of Hire at least ten (10) days before due. Payment of Hire shall be made to such U.S. Dollar account or accounts with such European office of a first class bank as Lessor shall designate in writing. Lessor shall not change such designations without Charterer's consent, which consent shall not be withheld unless Charterer determines that: (i) such change would increase Charterer's costs; or (ii) such change would expose Charterer to the risk of double payment. 6 The first payment of Hire shall be paid in same day funds before the close of business at the place of payment on the first business day of the calendar month beginning after the Hire Commencement Date. Except as otherwise provided in this Agreement, subsequent payments of Hire shall be paid in same day funds at the place of payment on the first business day of each applicable calendar month during the Initial Term or an extended term ("Hire Payment Date"). Hire shall accrue on a daily basis; provided that Hire for any periods that constitute less than a calendar day shall be a pro rata portion of Hire for such calendar day. If a Hire Payment Date falls on a day which is not a banking day at the place of payment, payment shall instead be made on the next succeeding day that is a banking day at such place. Any Hire paid but not earned shall be refunded on the next Hire Payment Date (or as otherwise provided under this Agreement) to Charterer by Lessor. 9.3 Upon request by Charterer, Lessor shall promptly pay to Charterer, or at the option of Charterer, at any time following an Event of Default by Lessor hereunder or a default under the Lessor Parent Company Guarantee, Charterer shall be entitled to deduct from the payments of Hire: (i) actual or reasonably estimated disbursements, if any, for Lessor's account; (ii) any advances to the master of the FPSO (the "Master") or to Lessor's affiliates, contractors, subcontractors, or agents for expenses or disbursements for Lessor's account; (iii) any previous overpayment of Hire, including payments made with respect to periods of Downtime; (iv) any sums due in respect of Lessor's failure to meet Lessor's performance undertakings under this Agreement; and (v) any other sums or credits to which Charterer is entitled under this Agreement. If a deduction is made based on an estimate, the next Hire payment shall be adjusted, if necessary, to reflect any difference between such estimate and the actual amount of deduction that Charterer is able to verify. All deductions from Hire shall be verified by Charterer by production of vouchers or supporting documentation corresponding to the deductions within thirty (30) days after the applicable Hire Payment Date. 9.4 Notwithstanding anything contained in this Article 9 to the contrary, the final payment of Hire hereunder shall be made on the date of redelivery of the FPSO to Lessor. Deductions, to the extent permitted by Article 9.3, from said final payment shall be those reasonably estimated by Charterer if the actual amounts have not been determined and also less the amount estimated by Charterer to become payable by Lessor for fuel and supplies on redelivery of the FPSO to Lessor as provided in Article 25. 9.5 (a) Should the FPSO become an actual total loss, Hire shall cease at the time of its loss or, if such time is unknown, at the time when the FPSO was last heard of. Should the FPSO become a total loss of any other kind, if approved in writing by Charterer in accordance with sub-clause (d) below, including, without limitation, a constructive, compromised, agreed or arranged total loss (a "constructive total loss"), Hire shall cease at the time of the casualty resulting in such loss. Within ninety (90) days after Hire has ceased under this Article 9.5, all monies owing to Charterer under the provisions of this Agreement at the time Hire ceases under this Article 9.5 shall be paid to Charterer, and likewise Lessor shall be paid the net amount of all sums due from Charterer. If the FPSO shall have been missing for at least forty-eight (48) hours when a payment of Hire would otherwise be due, such payment shall be postponed until the safety of the FPSO is ascertained. (b) Should the FPSO become an actual total loss or a constructive total loss (i) for reasons other than negligence or willful misconduct of Lessor Group and (ii) in circumstances where no Event of Default by Lessor or its affiliates, its Guarantor or the Operator (a "Lessor Party") has occurred and is continuing, this Agreement shall be deemed to be terminated as of the date on which the 7 obligation to pay Hire ceases in accordance with Article 9.5(a) without prejudice to (A) the payment obligations of Lessor and Charterer as described in Article 9.5(a) and (B) any other provisions which would otherwise survive termination of this Agreement which, for the avoidance of doubt, does not include any obligation to rebuild the FPSO or procure a new FPSO. (c) Should the FPSO become an actual total loss or a constructive total loss either (i) for reasons where the negligence or willful misconduct of a member of Lessor Group is a contributing factor or (ii) in circumstances where an Event of Default by a Lessor Party has occurred and is continuing, then, irrespective of such total loss, Charterer shall have the remedies set out in Article 31 hereof. (d) Lessor and its affiliates shall not be entitled to (i) claim under this Agreement or (ii) reach agreement with the insurers on the hull policies taken out by Lessor and its affilates that, in either case, the FPSO constitutes a total loss of any kind other than an actual total loss without the prior written approval of Charterer. (e) An actual total loss or a constructive total loss will not constitute in and of itself an Event of Default. 9.6 In the event Charterer fails to make any payment (including without limitation any payment of Hire) due and owing to Lessor under this Agreement, Lessor shall so notify Charterer. If Charterer fails to pay amounts due and owing within five (5) business days after receipt of such notice, Charterer shall pay to Lessor, in addition to all other amounts then due and owing, a late fee at a rate equal to one-month LIBOR plus two percent (2%) on the amounts then due and owing for the period of said fifth (5th) day until paid without prejudice to any other remedies under this Agreement. 9.7 All payments of Hire and other amounts due hereunder from one party to the other shall be made in U.S. Dollars by interbank transfer. Except as otherwise provided herein, all sums due by one party to the other shall be paid within 30 days of receipt of invoice. 9.8 Charterer shall be responsible for obtaining and shall use all reasonable efforts to obtain exchange control approval for payments under this Agreement. 10. CHANGE IN LAW 10.1 The Total Bareboat Rate is based on the tax laws of Thailand and Holland as of the date of this Agreement and assumes a tax burden of 1.1% of the Total Bareboat Rate. In the event there are any changes in Thailand tax laws or their interpretation which affect the cost to the Lessor of chartering the FPSO, the Total Bareboat Rate shall be revised upwards or downwards to take into account such change in costs; provided, however, Charterer shall not be obligated to pay any Thai, Dutch or U.S. tax burden up to a total amount equal to 2.2% of the Total Bareboat Rate and further provided Lessor shall use all reasonable efforts to maintain its present status under the tax treaty between Thailand and the Netherlands and shall take all reasonable actions to prevent or minimize any such increased expenses. Any increase in the total tax burden on the Total Bareboat Rate in excess of 2.2% of the Total Bareboat Rate attributable to any changes in Dutch tax laws shall be for Lessor's account. Any adjustment of said compensation shall be effective as of the effective date of the change in such tax burden; provided, Lessor shall furnish to Charterer the necessary supporting documentation evidencing such changes within a reasonable time. 10.2 The parties hereto do not believe that any U.S. taxes are applicable to payments made under this Agreement. To the extent that U.S. withholding taxes are assessed on Hire payable hereunder, Hire shall be increased such that the net Hire received by Lessor hereunder shall not be affected by such U.S. withholding taxes. Lessor agrees to use its best efforts to promptly obtain a refund of any such U.S. income taxes which have been withheld in excess of Lessor's U.S. tax obligations and to promptly repay such refund to Charterer. 8 11. TAXES Subject to Article 10, all taxes (including income and withholding taxes) which are due with respect to the payment of the Total Bareboat Rate pursuant to this Agreement shall be paid by Lessor or reimbursed to Charterer by Lessor, except that Thailand value added taxes ("VAT"), other Thailand sales/use taxes and Thailand customs and import duties applicable to the FPSO, shall be paid by Charterer or reimbursed to Lessor by Charterer. Charterer or its designee on the behalf of the Concessionaires shall be designated as the importer of the FPSO and be responsible for customs clearance and obtaining import licenses on the FPSO. 12.

On Redelivery, Lessor shall be free (i) to cut and either remove or abandon the anchor chains, the risers, buoyancy tanks and the control umbilicals (but so as to leave no hazard to shipping and to avoid damage to Charterer's wells, wellheads, pipelines, PLEMS or other equipment) and to remove the FPSO from the Offshore Site but without having any obligation to remove subsurface equipment or materials including piling or any other obligation to clear the Offshore Site and (ii) to remove any free crude oil not previously removed by Charterer at Charterer's expense. 26. REQUISITION 26.1 If the FPSO is seized, expropriated, confiscated, nationalized or requisitioned by any authority (other than the government, or any department, commission or agency thereof, of the Country of Registry, whether a legally constituted governmental authority or otherwise), and such seizure, expropriation, confiscation, nationalization or requisition has continued for a period of at least 30 consecutive days, this Agreement, at the option of Charterer, may continue in force or may be terminated at any time during the period of seizure, expropriation, confiscation, nationalization or requisition, provided that in the event Charterer elects to terminate, notice shall be given to Lessor by Charterer and compensation, as specified in Article 9, shall cease as of the date occurring 30 days prior to the date of notice of termination and the FPSO shall be deemed to have been Redelivered to Lessor by Charterer. If Charterer has previously paid any or all of such compensation in respect of such 30 day period, Lessor shall promptly refund such amount to Charterer. 26.2 In the event the FPSO is seized, expropriated, confiscated, nationalized or requisitioned by the government, or any department, commission or agency thereof, of the Country of Registry, whether a legally constituted governmental authority or otherwise, this Agreement shall be deemed terminated and compensation, as specified in Article 9.1, shall cease as of the date of seizure, expropriation, confiscation, nationalization or requisition, and the FPSO shall be deemed to have been redelivered to Lessor by Charterer. 26.3 In the event any seizure, expropriation, confiscation, nationalization or requisition of the FPSO occurs, Lessor shall use its best efforts to arrange the release of the FPSO therefrom (including, without limitation, changing the Country of Registry of the FPSO) and shall afford Charterer the opportunity to join in any such action. 27. GENERAL AND PARTICULAR AVERAGE General average if any shall be adjusted according to the York-Antwerp Rules 1994 or any subsequent modification thereof current at the time of the casualty. 28. SALVAGE All salvage and towage shall be for Lessor's benefit and the cost of repairing damage occasioned thereby shall be borne by Lessor. 29. AUDIT Lessor shall maintain its records which pertain to Articles 9 and 11 hereof in accordance with generally accepted international accounting principles and will keep copies of all applicable 19 documents, forms and third-party invoices, etc., and will permit Charterer to inspect such records at any time upon request during regular business hours. 30. DEFAULT The following events by either party hereto or any guarantor ("Guarantor") under a Joint Venturer Guarantee or Lessor Parent Company Guarantee (any such Guarantee being defined as a "Guarantee") shall constitute an Event of Default: a) failure to observe any material covenant, condition or agreement to be performed or observed by said party hereunder or any Guarantor under the Guarantees; or b) any representation or warranty made herewith or pursuant hereto or pursuant to any of the Guarantees shall prove to be incorrect at any time in any material respect; or c) said party or Guarantor shall become insolvent or bankrupt or consent to the appointment of a trustee or receiver, or a trustee or receiver shall be appointed for said party or for a substantial part of its property without its consent and shall not be dismissed for a period of thirty (30) days, or bankruptcy, reorganization or insolvency proceedings shall be instituted by or against said party and, if instituted against said party, shall not be dismissed for a period of thirty (30) days, and at any time thereafter so long as the same shall be continuing; or d) an Event of Default with respect to that party or its Guarantor shall have occurred under the Operating Agreement (for purpose of this paragraph d) only, an Event of Default by Operator under the Operating Agreement shall be deemed an Event of Default by Lessor hereunder); or e) A Force Majeure Event shall have occurred preventing payment by either party and such failure to pay continues unremedied for a period of 60 consecutive days. 31. REMEDIES 31.1 Upon the occurrence of an Event of Default by Lessor or its affiliate and at any time thereafter so long as the same shall be continuing, Charterer may, at its option, upon ninety (90) days' notice thereof to Lessor, declare this Agreement to be in default; and, at any time thereafter, so long as Lessor shall not have remedied or have commenced and at all times thereafter diligently acted to remedy all outstanding Events of Default, Charterer (a) may terminate this Agreement, compensation as specified in Article 9.1 shall cease as of the date of termination and Charterer shall redeliver the FPSO to Lessor as if the FPSO were being redelivered pursuant to Article 25 hereof, or (b) accelerate its right to exercise the Purchase Option at a price to be determined by reference to Appendix C (offsetting any damages which have been established at the time of such purchase against the purchase price of the FPSO) and terminate compensation under Article 9.1. Lessor shall be liable for any and all damages to Charterer resulting from termination of this Agreement and for all legal fees and any other costs and expenses whatsoever incurred by Charterer by reason of the occurrence of any Event of Default or by reason of the exercise by Charterer of any remedy hereunder, including, without limitation, any costs and expenses incurred by Charterer in connection with Redelivery of the FPSO. Notwithstanding the remedies available to Charterer under this Article 31, the provisions of Article 18.9 shall apply so as to limit the damages of Charterer and any guarantors of Charterer's obligations hereunder, PROVIDED that if Lessor shall breach its obligation other than for reasons wholly outside its control to sell the FPSO to Charterer if Charterer exercises its Purchase Option under sub-clause (b) above, Lessor shall be liable to such guarantors for direct damages to the guarantors or any of their affiliates which are parties to the Gas Sales Agreement arising under Articles XV or XVIII of the Gas Sales Agreement. To the extent that such guarantors (and such affiliates) claim direct damages under the Gas Sales Agreement as provided in the preceding sentence, such guarantors and affiliates must use their reasonable efforts to mitigate their damages. Charterer must use reasonable efforts to mitigate its damages. 20 31.2 Upon the occurrence of an Event of Default by Charterer or its affiliate (provided that such Event of Default did not arise out of or result from actions, or omissions to act, of Operator under the Operating Agreement) and at any time thereafter so long as the same shall be continuing, Lessor may, at its option, upon ninety (90) (or, in the case of an Event of Default based on a failure to pay money when due (including a failure by reason of Force Majeure), thirty (30)) days' notice thereof to Charterer, declare this Agreement to be in default; and, at any time thereafter, so long as Charterer shall not have remedied or (except as to an Event of Default based on a failure to pay money when due) have commenced and at all times thereafter diligently acted to remedy all outstanding Events of Default Lessor may do, and Charterer shall comply with, one or more of the following, as Lessor in its sole discretion shall so elect, to the extent permitted by, and subject to compliance with any mandatory requirements of applicable law then in effect. Lessor must use reasonable efforts to mitigate its damages and shall apply any amounts received from the sale or re-charter (for a period equal to the remainder of the term of this Agreement) of the FPSO (after deducting Lessor's direct out-of-pocket expenses of making the FPSO ready for sale or re-charter) to reduce the amount of any charter hire and other amounts payable by Charterer to Lessor pursuant to the last paragraph of this Article 31.2. To the extent that Charterer fails to maintain in force any insurance coverage described in Article 17.3 and is not diligently acting to replace such coverage, Lessor shall be entitled to obtain such insurance for the account of Charterer. a) Lessor may terminate this Agreement. b) Upon written demand, Lessor may cause Charterer to, and Charterer hereby agrees that it will, redeliver the FPSO to Lessor within a reasonable period of time not to exceed 45 days and in the same manner and in the same condition as if the FPSO were being redelivered pursuant to Article 25 hereof; or Lessor or its agent, at Lessor's option, may, but shall be under no obligation to, retake the FPSO irrespective of whether Charterer or any other person may be in possession of the FPSO, upon 24 hours prior notice but without prior demand and without legal process, and for that purpose Lessor or its agent may take possession thereof. c) Lessor or its agent may sell the FPSO at public or private sale, with notice to Charterer, or otherwise may dispose of, hold, use, operate, charter (whether for a period greater or less than the balance of what would have been the charter period for the FPSO in the absence of the termination of Charterer's rights to the FPSO) to others or keep idle, all on such terms and conditions and at such place or places as Lessor may determine. In addition, Charterer shall be liable for and shall pay to Lessor within thirty days after Lessor takes redelivery or possession of the FPSO a lump sum equal to any and all additional Hire payable during the Initial Term and for all legal fees and any other costs and expenses whatsoever incurred by Lessor by reason of the occurrence of any Event of Default or by reason of the exercise by Lessor of any remedy hereunder, including, without limitation, any costs and expenses incurred by Lessor in connection with the Redelivery or retaking of the FPSO. 31.3 Each party's remedies referred to in this Article 31 are intended to be the exclusive remedies of such party under this Agreement; PROVIDED, HOWEVER, that either party may enforce performance of these remedies by all legal or equitable means. 31.4 No express or implied waiver by either party of any Event of Default shall be in any way, or be construed to be, a waiver of any further or subsequent Event of Default. 32. MISCELLANEOUS 32.1 a) All terms and conditions of this Agreement shall be binding upon and shall enure to the benefit of the parties hereto and their respective successors and permitted assigns. Any purported assignment in contravention of this Article 32 shall be null and void. 21 b) Charterer shall be entitled to assign its rights, duties and obligations hereunder to an affiliate without the consent of Lessor PROVIDED that Lessor receives simultaneously with such assignment guarantees from the Joint Venturers in respect of such assignee's obligations in the terms set out in Article 5 hereof. c) Any party having rights under this Agreement shall be entitled to pledge and/or assign its rights and, to the extent possible, and if requested, its duties and obligations under this Agreement by way of security to any lending institution providing financing for the transactions contemplated hereby or related to the development of the Tantawan Field or a collateral agent on their behalf provided that any such pledge or assignment does not release the assignor or any guarantor of the assignor's obligations hereunder, from any of their respective obligations to the Lessor or the Charterer as the case may be. d) Charterer shall not subcharter the FPSO to any party including an affiliate without the prior written consent of Lessor such consent not to be unreasonably withheld. Save as specifically provided above, neither party hereto shall be entitled to assign any rights or obligations under this Agreement without the prior consent of the other party, not to be unreasonably withheld. Charterer shall maintain a written record that identifies Lessor as the person entitled to payments under this Agreement. In the event of an assignment by Lessor of any of its rights under this Agreement, such assignment will be reflected on the record maintained by Charterer. 22 [THE REMAINDER OF THIS PAGE IS INTENTIONALLY BLANK] 23 32.2 This Agreement may be executed in one or more counterparts, all of which, taken together, shall constitute one original document. 32.3 Except as specifically provided herein to the contrary, each party hereto intends that this Agreement shall not benefit or create any right or cause of action to any person other than parties hereto or their permitted assignees. 32.4 The making, execution and delivery of this Agreement by the parties hereto have been induced by no representation, statements, warranties or agreements other than those herein expressed or set forth in the attached exhibits or schedules. This Agreement and such exhibits or schedules embody the entire understanding of the parties, and there are no further or other agreements or understandings, written or oral, in effect between the parties relating to the subject matter hereof, unless expressly referred to by reference herein. 32.5 This Agreement may be amended or modified and any condition herein specified may be waived by mutual consent of the parties by a written instrument executed on behalf of the parties. 32.6 The captions contained in this Agreement are for convenience of reference only and do not form a part of this Agreement and shall not affect the interpretation hereof. 32.7 If any portion of this Agreement shall be deemed by an arbitration tribunal or a court of competent jurisdiction to be unenforceable, the remaining portions shall be valid and enforceable only if, after excluding the portion deemed to be unenforceable, the remaining terms hereof shall provide for the consummation of the transactions contemplated herein in substantially the same manner as originally set forth at the date this Agreement was executed. 32.8 Each of the parties hereto intends this Agreement will be treated as a lease of the FPSO from Lessor to Charterer. Neither Charterer, Lessor, nor any of their respective affiliates will take any action nor file any document with any governmental authority including, without limitation, any tax return, which is inconsistent with such characterization of this Agreement as a lease. IN WITNESS WHEREOF, the parties have caused this Agreement to be executed in duplicate as of the 9th day of February, 1996. TANTAWAN PRODUCTION B.V. TANTAWAN SERVICES, L L C By: /s/ G.
