No such determination of acceptability shall in any way absolve a non-participating Party from its obligation to meet each cash call including any cash call in respect of damages and losses and/or the costs of remedying the same in accordance with the terms of this Agreement. If such Party obtains other insurance, such insurance shall contain a waiver of subrogation in favor of all the other Parties, the Operator and their insurers but only in respect of their interests under this Agreement.

4.8 Commingling of Funds

Operator may commingle with its own funds the monies which Operator receives from or for the Joint Account pursuant to this Agreement.

less than twenty percent (20%), Operator shall be required to promptly notify the other Parties. The Operating Committee shall then vote within thirty (30) Days of such notification on whether or not a successor Operator should be named pursuant to Article 4.11.

4.11 Appointment of Successor

When a change of Operator occurs pursuant to Article 4.9 or Article 4.10:

(7) As soon as any Exclusive Operation is fully subscribed pursuant to Article 7.2(E)(6) Operator (subject to Article 7.11(F)), shall commence such Exclusive Operation as promptly as practicable and conduct it with due diligence in accordance with this Agreement.

(8) If the Exclusive Operation is conducted, the Consenting Parties shall bear the sole liability and expense of such Exclusive Operation, with each Consenting Party bearing a fraction of such liability and expense, the numerator of which is such Consenting Party’s Participating Interest as stated in Article 3.2(A) and the denominator of which is the aggregate of the Participating Interests of the Consenting Parties as stated in Article 3.2(A), or as the Consenting Parties may otherwise agree.

(8) If such Exclusive Operation has not been commenced within a ninety (90) Days (excluding any extension specifically agreed by all Parties or allowed by the force majeure provisions of Article XVI) after the date of the notice given by Operator under Article 7.2(E)(6), the right to conduct such Exclusive Operation shall terminate. If any Party still desires to conduct such Exclusive Operation, notice proposing such operation must be resubmitted to the Parties in accordance with Article V, as if no proposal to conduct an Exclusive Operation had been previously made.

7.3 Responsibility for Exclusive Operations

(A) The Consenting Parties shall bear in accordance with the Participating Interests agreed under Article 7.2(E) the entire cost and liability of conducting an Exclusive Operation and shall indemnify the Non-Consenting Parties from any and all costs and liabilities incurred incident to such Exclusive Operation (including but not limited to all costs, expenses or liabilities for environmental, consequential, punitive or any other similar indirect damages or losses arising from business interruption, reservoir or formation damage, inability to produce petroleum, loss of profits, pollution control and environmental amelioration or rehabilitation) and shall keep the Contract Area free and clear of all liens and encumbrances of every kind created by or arising from such Exclusive Operation.

(B) Notwithstanding Article 7.3(A), each Party shall continue to bear its Participating Interest share of the cost and liability incident to the operations in which it participated, including but not limited to plugging and abandoning and restoring the surface location, but only to the extent those costs were not increased by the Exclusive Operation.

7.4 Consequences of Exclusive Operations

(A) With regard to any Exclusive Operation, for so long as a Non-Consenting Party has the option under Article 7.4(C) to reinstate the rights it relinquished under Article 7.4(B), such Non-Consenting Party shall be entitled to have access concurrently with the Consenting Parties to all data and other information relating to such Exclusive Operation, other than G & G Data obtained in an Exclusive Operation. If a Non-Consenting Party desires to receive and acquire the right to use such G & G Data, then such Non-Consenting Party shall have the right to do so by paying to the Consenting Parties two hundred percent 200%) of the Non-Consenting Party’s Participating Interest share as set out in Article 3.2(A) of the cost incurred in obtaining such G & G Data.

If the Parties decide to drill a well or wells within the area covered by the G & G Data obtained in an Exclusive Operation, the Non-Consenting Party shall pay to the Consenting Parties three hundred percent (300%) of the Non-Consenting Party’s Participating Interest share of the cost incurred in obtaining such G & G Data which shall then become Joint Property.

(B) Subject to Article 7.4(C), Article 7.6(E) and Article 7.8, each Non-Consenting Party shall be deemed to have relinquished to the Consenting Parties, and the Consenting Parties shall be deemed to own, in proportion to their respective Participating Interests in any Exclusive Operation:

(1) All of each such Non-Consenting Party’s right to participate in further operations in the well or Deepened or Sidetracked portion of a well in which the Exclusive Operation was conducted and on any Discovery made or appraised in the course of such Exclusive Operation; and

(2) All of each such Non-Consenting Party’s right pursuant to the Contract to take and dispose of Hydrocarbons produced and saved:

(a) From the well or Deepened or Sidetracked portion of a well in which such Exclusive Operation was conducted, and

(b) From any wells drilled to appraise or develop a Discovery made or appraised in the course of such Exclusive Operation

(C) A Non-Consenting Party shall have only the following options to reinstate the rights it relinquished pursuant to Article 7.4(B):

(1) If the Consenting Parties decide to appraise a Discovery made in the course of an Exclusive Operation, the Consenting Parties shall submit to each Non-Consenting Party the approved appraisal program. For thirty (30) Days (or forty-eight (48) hours if the drilling rig or seismic acquisition vehicle which is to be used in such appraisal program is standing by under contract in the Contract Area) from receipt of such appraisal program, each Non-Consenting Party shall have the option to reinstate the rights it relinquished pursuant to Article 7.4(B) and to participate in such appraisal program. The Non-Consenting Party may exercise such option by notifying Operator within the period specified above that such Non-Consenting Party agrees to bear its Participating Interest share of the expense and liability of such appraisal program, to pay the lump sum amount as set out in Article 7.5(A) and to pay the Cash Premium as set out in Article 7.5(B).

(2) If the Consenting Parties decide to develop a Discovery made or appraised in the course of an Exclusive Operation, the Consenting Parties shall submit to the Non-Consenting Parties a Development Plan substantially in the form intended to be submitted to the Government under the Contract. For sixty (60) Days from receipt of such Development Plan or such lesser period of time prescribed by the contract, each Non-Consenting Party shall have the option to reinstate the rights it relinquished pursuant to Article 7.4(B) and to participate in such Development Plan. The Non-Consenting Party may exercise such option by notifying the Party proposing to act as Operator for such Development Plan within the period specified above that such Non-Consenting Party agrees to bear its Participating Interest share of the liability and expense of such Development Plan and such future operating and producing costs, to pay the lump sum amount as set out in Article 7.5(A) and to pay the Cash Premium as set out in Article 7.5(B);

(3) If the Consenting Parties decide to Deepen, Complete, Sidetrack, Plug Back or Recomplete an Exclusive Well and such further operation was not included in the original proposal for such Exclusive Well, the Consenting Parties shall submit to the Non-Consenting Parties the approved AFE for such further operation. For thirty (30) Days (or forty-eight (48) hours if the drilling rig or seismic acquisition vehicle which is to be used in such operation is standing by under contract in the Contract Area) from receipt of such AFE, each Non-Consenting Party shall have the option to reinstate the rights it relinquished pursuant to Article 7.4(B) and to participate in such operation. The Non-Consenting Party may exercise such option by notifying the Operator within the period specified above that such Non-Consenting Party agrees to bear its Participating Interest share of the liability and expense of such further operation, to pay the lump sum amount as set out in Article 7.5(A) and to pay the Cash Premium as set out in Article 7.5(B).

A Non-Consenting Party shall not be entitled to reinstate its rights any other type of operation.

(D) If a Non-Consenting Party does not properly and within the relevant time limit exercise such option, including paying in a timely manner accordance with Article 7.5 all lump sum amounts and Cash Premiums, if any, due to the Consenting Parties, such Non-Consenting Party shall have forfeited the options as set out in Article 7.4(C) and the right to participate in the proposed program, unless such program, plan or operation is materially modified or expanded (in which case a new notice and option shall be given to such Non-Consenting Party under Article 7.4(C)).

(E) A Non-Consenting Party shall become a Consenting Party with regard to an Exclusive Operation at such time as the Non-Consenting Party gives notice pursuant to Article 7.4(C); provided that such Non-Consenting Party shall have paid any lump sum amount and/or Cash Premium for such Exclusive Operation as required under this Article VII. Such Non-Consenting Party shall be entitled to recover its Participating Interest share of expenses paid pursuant to Article 7.5(A) (but not the amount of any associated Cash Premium). The Participating Interest of such Non-Consenting Party in such Exclusive Operation shall be its Participating Interest set out in Article 3.2(A). The Consenting Parties shall contribute to the Participating Interest of the Non-Consenting Party in proportion to the excess Participating Interest that each received under Article 7.2(F). If all Parties participate in the proposed operation, then such operation shall be conducted as a Joint Operation pursuant to Article V.

(F) If after the expiry of the period in which a Non-Consenting Party may exercise its option to participate in a Development Plan the Consenting Parties desire to proceed, the Operator (or if the Operator is unwilling to act, then the Party chosen by the Consenting Parties proposing to act as Operator for such development) shall give notice to the Government under the appropriate provision of the Contract requesting a meeting to advise the Government that the Consenting Parties consider the Discovery to be a Commercial Discovery. Following such meeting such Operator for such development shall apply for an Exploitation Area (if applicable in the Contract). Unless the Development Plan is materially modified or expanded prior to the commencement of operations under such plan (in which case a new notice and option shall be given to the Non-Consenting Parties under Article 7.4(C)), each Non-Consenting Party to such Development Plan shall be deemed to have:

(a) Elected not to apply for an Exploitation Area covering such development; and

(b) Forfeited all economic interest in such Exploitation Area; and

(c) Assumed a fiduciary duty to exercise its legal interest in such Exploitation Area for the benefit of the Consenting Parties.

Such Non-Consenting Party shall be deemed to have withdrawn from this Agreement to the extent it relates to such Exploitation Area, even if the Development Plan is modified or expanded subsequent to the commencement of operations under such Development Plan and shall be further deemed to have forfeited all rights to such Exploitation Area including any right to participate in the construction and ownership of facilities outside such Exploitation Area designed solely for the use of such Exploitation Area.

7.5 Premium to Participate in Exclusive Operations

(A) Within thirty (30) Days of the exercise of its option under Article 7.4(C), each such Non-Consenting Party shall pay in immediately available funds to the Consenting Parties in proportion to their respective Participating Interest in such Exclusive Operations a lump sum amount payable in United States Dollars. Such lump sum amount shall be equal to such Non-Consenting Party’s Participating Interest share of all liabilities and expenses, including overhead, that were incurred in every Exclusive Operation relating to the Discovery, or well, as the case may be, in which the Non-Consenting Party desires to reinstate the rights it relinquished pursuant to Article 7.4(B), and that were not previously paid by such Non-Consenting Party.

(B) In addition to Article 7.5(A), if a Cash Premium is due, then within thirty (30) Days of the exercise of its option under Article 7.4(C) each such Non-Consenting Party shall pay in immediately available funds in United States Dollars, to such Consenting Parties in proportion to their respective Participating Interests a Cash Premium equal to the total of:

(1) five hundred percent (500%) of such Non-Consenting Party’s Participating Interest share of all liabilities and expenses, including overhead, that were incurred in any Exclusive Operations relating to the obtaining of the portion of the G & G Data which pertains to the Discovery, and that were not previously paid by such Non-Consenting Party; plus

(2) nine hundred percent (900%) of such Non-Consenting Party’s Participating Interest share of all liabilities and expenses, including overhead, that were incurred in any Exclusive Operations relating to the drilling, Deepening, Testing, Completing, Sidetracking, Plugging Back, Recompleting and Reworking of the Exploration Well which made the Discovery in which the Non-Consenting Party desires to reinstate the rights it relinquished pursuant to Article 7.4(B), and that were not previously paid by such Non-Consenting Party; plus

(3) four hundred percent (400%) of the Non-Consenting Party’s Participating Interest share of all liabilities and expenses, including overhead, that were incurred in any Exclusive Operations relating to the drilling, Deepening, Testing, Completing, Sidetracking, Plugging Back, Recompleting and Reworking of the Appraisal Well(s) which delineated the Discovery in which the Non-Consenting Party desires to reinstate the rights it relinquished pursuant to Article 7.4(B), and that were not previously paid by such Non-Consenting Party.

7.6 Order of Preference of Operations

(A) Except as otherwise specifically provided in this Agreement, if any Party desires to propose the conduct of an operation that will conflict with an existing proposal for an Exclusive Operation, such Party shall have the right exercisable for five (5) Days, or twenty-four (24) hours if the drilling rig or seismic vessel to be used is standing by under contract in the Contract Area, from receipt of the proposal for the Exclusive Operation, to deliver to all Parties entitled to participate in the proposed operation such Party’s alternative proposal. Such alternative proposal shall contain the information required under Article 7.2(A).

(B) Each Party receiving such proposals shall elect by delivery of notice to Operator within the appropriate response period set out in Article 7.2(B) to participate in one of the competing proposals. Any Party not notifying Operator within the response period shall be deemed to have voted against the proposal.

(C) The proposal receiving the largest aggregate Participating Interest vote shall have priority over all other competing proposals. In the case of a tie vote, the Operator shall choose among the proposals receiving the largest aggregate Participating Interest vote. Operator shall deliver notice of such result to all Parties entitled to participate in the operation within five (5) Days of the end of the response period, or twenty-four (24) hours if the drilling rig or seismic acquisition vehicle to be used is standing by under contract in the Contract Area.

(D) Each Party shall then have two (2) Days (or twenty-four (24) hours if the drilling rig or seismic acquisition vehicle to be used is standing by under contract in the Contract Area) from receipt of such notice to elect by delivery of notice to Operator whether such Party will participate in such Exclusive Operation, or will relinquish its interest pursuant to Article 7.4(B). Failure by a Party to deliver such notice within such period shall be deemed an election not to participate in the prevailing proposal.

7.7 Stand-By Costs

(A) When an operation has been performed, all tests have been conducted and the results of such tests furnished to the Parties, stand by costs incurred sending response to any Party’s notice proposing an Exclusive Operation for Deepening, Testing, Sidetracking, Completing, Plugging Back, Recompleting, Reworking or other further operation in such well (including the period required under Article 7.6 to resolve competing proposals) shall be charged and borne as part of the operation just completed. Stand by costs incurred subsequent to all Parties responding, or expiration of the response time permitted, whichever first occurs, shall be charged to and borne by the Parties proposing the Exclusive Operation in proportion to their Participating Interests, regardless of whether such Exclusive Operation is actually conducted.

(B) If a further operation is proposed while the drilling rig or seismic acquisition vehicle to be utilized is on location, any Party may request and receive up to five (5) additional Days after expiration of the applicable response period specified in Article 7.2(B) within which to respond by notifying Operator that such Party agrees to bear all stand by costs and other costs incurred during such extended response period. Operator may require such Party to pay the estimated stand by time in advance as a condition to extending the response period. If more than one Party requests such additional time to respond to the notice, stand by costs shall be allocated between such Parties on a Day-to-Day basis in proportion to their Participating Interests.

7.8 Use of Property

(A) The Parties participating in any Deepening, Testing, Completing, Sidetracking, Plugging Back, Recompleting or Reworking of any well drilled under this Agreement shall be permitted to use, free of cost, all casing, tubing and other equipment in the well that is not needed for operations by the Parties who originally bore the costs of the wellbore.

On abandonment of a well in which operations with differing participation have been conducted, the Parties abandoning the well shall account for all equipment in the well to the Parties who originally bore the costs of such equipment by tendering to them their respective Participating Interest shares of the value of such equipment less the cost of salvage.

(B) Spare capacity in equipment that is constructed pursuant to this Agreement and used for processing or transporting oil and gas after it has passed through primary separators and dehydrators (including without limitation treatment facilities, gas processing plants and pipelines) shall be available for use by any Party for Hydrocarbon production from the Contract Area on the terms set forth below. All Parties desiring to use such equipment shall nominate capacity in such equipment on a monthly basis by notice to Operator at least ten (10) days prior to the beginning of each month. Operator may nominate capacity for the Parties that originally bore the costs of the equipment if they so elect. If at any time the capacity nominated exceeds the total capacity of the equipment, the capacity of the equipment shall be allocated in the following priority: (1) first, to the Parties that originally bore the costs of the equipment up to their respective Participating Interest or if funded under a Participation Agreement, their Exploitation Participating Interest shares of total capacity, (2) second, to Parties that originally bore the costs of the equipment desiring to use capacity in excess of their Participating Interest or if funded in such proportion, Exploitation Participating Interest shares, in proportion to the Participating Interest or Exploitation Participating Interest of each such Party and (3) third, to Parties not who did not fund the costs of the equipment, in proportion to their Participating Interests in the Agreement. Parties that originality bore the costs of the equipment shall be entitled to use up to their Participating Interest or if applicable Exploitation Participating Interest share of total capacity without payment of a fee under this Article 7.8(B). Otherwise, each Party using equipment pursuant

to this Article 7.8(B) shall pay to the Parties that originally bore the costs of the equipment monthly throughout the period of use an arm’s-length fee based upon third party charges for similar services in the vicinity of the Contract Area.

If no arm’s-length rates for such services are available, then the party desiring to use equipment pursuant to this Article 7.8(B) shall pay to the Parties that originally bore the costs of the equipment a monthly fee equal to (1) that portion of the total cost of the equipment, divided by the number of months of useful life established for such equipment under the tax law of the host country, that the capacity made available to such Party on a fee basis under this Article 7.8(B) bears to the total capacity of the equipment plus (2) that portion of the monthly cost of maintaining, operating and financing the equipment that the capacity made available to such Party on a fee basis under this Article 7.8(B) bears to the total capacity of the equipment.

(C) Payment for the use of equipment under Article 7.8(B) shall not result in an acquisition of any additional interest in the equipment by the paying Parties. However, such payments shall be included in the costs which the paying Parties are entitled to recoup under Article 7.5.

(D) Parties electing to use spare capacity in equipment pursuant to Article 7.8(B) shall indemnify the Parties that originally bore the costs of the equipment against any and all costs and liabilities incurred as a result of such use (including but not limited to all costs, expenses or liabilities for environmental, consequential, punitive or other similar indirect damages or losses, whether arising from business interruption, reservoir or formation damage, inability to produce petroleum, loss of profits, pollution control, environmental amelioration or rehabilitation or otherwise), but excluding costs and liabilities for which the Operator is solely responsible under Article 4.6.

7.9 Miscellaneous

(A) Each Exclusive Operation shall be carried out by the Consenting Parties acting as the Operating Committee, subject to the provisions of this Agreement applied mutatis mutandis to such Exclusive Operation and subject to the terms and conditions of the Contract.

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

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

(D) Operator, it is conducting an Exclusive Operation for the Consenting Parties, regardless of whether it is participating in that Exclusive Operation, shall be entitled to request cash advances and shall not be required to use its own funds to pay any cost and expense and shall not be obliged to commence or continue Exclusive Operations until cash advances requested have been made, and the Accounting Procedure shall apply to Operator in respect of any Exclusive Operations conducted by it.

(E) Should the submission of a Development Plan be approved in accordance with Article 5.9, or should any Party propose a development in accordance with Article VII, with either proposal not calling for the conduct of additional appraisal drilling, and should any Party wish to drill an additional Appraisal Well prior to development, then the Party proposing the Appraisal Well as an Exclusive Operation shall be entitled to proceed first, but without the right to future reimbursement pursuant to Article 7.5. If such an Appraisal Well is produced, the Consenting Party or Parties shall own and have the right to take in kind and separately dispose of all of the Non-Consenting Parties’ Entitlement from such Appraisal Well until the value thereof, determined in accordance with Article 7.5(F), equals one hundred percent (100 %) of such Non-Consenting Parties’ Participating Interest share of all liabilities and expenses, including overhead, that were incurred in any Exclusive Operations relating to the Appraisal Well. If, as the result of drilling such Appraisal Well as an Exclusive Operation, the Party proposing to apply for an Exploitation Area decides to not develop the reservoir, then each Non-Consenting Party who voted in favor of such Development Plan prior to the drilling of such Appraisal Well shall pay to the Consenting Party the amount such Non-Consenting Party would have paid had such Appraisal Well been drilled as a Joint Operation.

(F) The value of Hydrocarbons received by a Consenting Party for the purposes of Article 7.9(E) shall be the weighted average price per Barrel (f.o.b the point of delivery of the Cost Oil and Profit Oil to the Consenting Parties) which such Consenting Party receives from the sale of such Hydrocarbons to non-affiliated purchasers in arms length transactions. For sales to Affiliates, the price so used shall be the price at which Hydrocarbons of similar grade, gravity and quality (adjusted for differentials in accordance with regularly established practice) were sold generally on world markets during the particular period of sale, in free and fair arms-length transactions, with due adjustments being made for differing geographical locations. Notwithstanding the fact that royalty or any other payment obligation to the Government is based on an “official” or “Government” stated price, the price used for calculation of the vale of Hydrocarbons for the purposes of Article 7.9(E) shall be the price determined in accordance with this Article 7.9(E).

(G) If the Operator is a Non-Consenting Party to an Exclusive Operation to develop a Discovery, then subject to obtaining any necessary Government approvals the Operator may resign as Operator for the Exploitation Area for such Discovery and the Consenting Parties shall then select a Party to serve as Operator.

ARTICLE VIII — DEFAULT

8.1 Default and Notice

Any Party that fails to pay when due its Participating Interest share of Joint Account expenses, including cash advances and interest, shall be in default under this Agreement (a “Defaulting Party”). Operator, or any non-defaulting Party in the case Operator is the Defaulting Party, shall promptly give notice of such default to the Defaulting Party and each of the non-defaulting Parties (the “Default Notice”). The amount not paid by the Defaulting Party shall bear interest from the date due until paid in full at the Agreed Interest Rate.

8.2 Operating Committee Meetings and Data

Beginning five (5) Business Days from the date of the Default Notice, and thereafter while the Defaulting Party remains in default, the Defaulting Party shall not be entitled to attend Operating Committee or subcommittee meetings or to vote on any matter coming before the Operating Committee or any subcommittee until all of its defaults have been remedied (including payment of accrued interest). Unless agreed otherwise by the non-defaulting Parties, the voting interest of each non-defaulting Party during this period shall be its percentage of the total Participating Interests of the non-defaulting Parties. Any matters requiring a unanimous vote of the Parties shall not require the vote of the Defaulting Party. In addition, beginning five (5) Business Days from the date of the Default Notice, and thereafter while the Defaulting Party remains in default, the Defaulting Party shall not have access to any data or information relating to Joint Operations. During this period, the non-defaulting Parties shall be entitled to trade data without such Defaulting Party’s consent, and the Defaulting Party shall have no right to any data received in such a trade unless and until its default is remedied in full. The Defaulting Party shall be deemed to have elected not to participate in any Joint Operations or Exclusive Operations that are voted upon at least five (5) Business Days after the date of the Default Notice but before all of its defaults have been remedied to the extent such an election would be permitted by Article 5.13(B) of this Agreement. The Defaulting Party shall he deemed to have approved, and shall join with the non-defaulting Parties in taking, any other actions voted on during that period.

8.3 Allocation of Defaulted Accounts

(A) The Party providing the Default Notice pursuant to Article 8.1 shall include in the Default Notice to each non-defaulting Party a statement of the sum of money that the non-defaulting Party is to pay as its portion (such portion being in the ratio that each non-defaulting Party’s Participating Interest bears to the Participating Interests of all non-defaulting Parties) of the amount in default (excluding interest), subject to the terms of this Article 8.3. If the Defaulting Party remedies its default in full within five (5) Business Days from the date of the Default Notice, the notifying Party shall promptly notify each non-defaulting Party by telephone and facsimile, and the non-defaulting Parties shall be relieved of their obligation to pay a share of the amounts in default. Otherwise, each non-defaulting Party shall pay Operator, within five (5) Business Days after receipt of the Default Notice, its share of the amount which the Defaulting Party failed to pay. If any non-defaulting Party fails to pay its share of the amount in default as aforesaid, such Party shall thereupon be a Defaulting Party subject to the provisions of this Article VIII. The non-defaulting Parties which pay the amount owed by any Defaulting Party shall be entitled to receive their respective shares of the principal and interest payable by such Defaulting Party pursuant to this Article VIII.

(B) If Operator is a Defaulting Party, then all payments otherwise payable to Operator for Joint Account costs pursuant to this Agreement shall be made to the notifying Party instead until the default is cured or a successor Operator appointed. The notifying Party shall maintain such funds in a segregated account separate from its own funds and shall apply such funds to third party claims due and payable from the Joint Account of which it has notice, to the extent Operator would be authorized to make such payments under the terms of this Agreement. The notifying Party shall be entitled to bill or cash call the other Parties in accordance with the Accounting Procedure for proper third party charges that become due and payable during such period to the extent sufficient funds are not available. When Operator has cured its default or a successor Operator is appointed, the notifying Party shall turn over all remaining funds in the account to Operator and shall provide Operator and the other Parties with a detailed accounting of the funds received and expended during this period. The notifying Party shall not be liable for damages, losses, costs, expenses or liabilities arising as a result of its actions under this Article 8.3(B) except to the extent Operator would be liable under Article 4.6.

8.4 Remedies

(A) During the continuance of a default, the Defaulting Party shall not have a right to its Entitlement which shall vest in and be the property of the non-defaulting Parties. Operator (or the notifying Party if Operator is a Defaulting Party) shall be authorized to sell such Entitlement in an arm’s-length sale on terms that are commercially reasonable under the circumstances and, after deducting all costs, charges and expenses incurred in connection with such sale, pay the net proceeds to the non-defaulting Parties in proportion to the amounts they are owed by the Defaulting

Party hereunder (and apply such net proceeds toward the establishment of a reserve fund under Article 8.4(C), if applicable) until all such amounts are recovered and such reserve fund is established. Any surplus remaining shall be paid to the Defaulting Party, and any deficiency shall remain a debt due from the Defaulting Party to the non-defaulting Parties. When making sales under this Article 8.4(A), the non-defaulting Parties shall have no obligation to share any existing market or obtain a price equal to the price at which their own production is sold.

(B) If Operator disposes of any Joint Property or any other credit or adjustment is made to the Joint Account while a Party is in default. Operator (or the notifying Party if Operator is a Defaulting Party) shall be entitled to apply the Defaulting Party’s Participating Interest share of the proceeds of such disposal, credit or adjustment against all amounts owing by the Defaulting Party to the non-defaulting Parties hereunder (and toward the establishment of a reserve fund under Article 8.4(C), if applicable). Any surplus remaining shall be paid to the Defaulting Party, and any deficiency shall remain a debt due from the Defaulting Party to the non-defaulting Parties.

(C) The non-defaulting Parties shall be entitled to apply proceeds received under Articles 8.4(A) and 8.4(B) toward the creation of a reserve fund in an amount equal to the Defaulting Party’s Participating Interest share of (i) the estimated cost to abandon any wells and other property in which the Defaulting Party participated, (ii) the estimated cost of severance benefits for local employees upon cessation of operations and (iii) any other identifiable costs that the non-defaulting Parties anticipate will be incurred in connection with the cessation of operations.

(D) If a Defaulting Party fails to remedy its default by the forty-fifth (45th) Day following the date of the Default Notice, then, without prejudice to any other rights available to the non-defaulting Parties to recover amounts owing to them under this Agreement each non-defaulting Party shall have the option, exercisable at anytime thereafter until the Defaulting Party has completely cured its defaults, to require that the Defaulting Party completely withdraw from his Agreement and the Contract. Such option shall be exercised by notice to the Defaulting Party and each non-defaulting Party. If such option is exercised, the Defaulting Party shall be deemed to have transferred, pursuant to Article 13.6, effective on the date of the non-defaulting Party’s notice, all of its right, title and beneficial interest in and under this Agreement and the Contract to the non-defaulting Parties. The Defaulting Party shall, without delay following any request from the non-defaulting Parties, do any and all acts required to be done by applicable law or regulation in order to render such transfer legally valid, including, without limitation, obtaining all governmental consents and approvals, and shall execute any and all documents and take such other actions as may be necessary in order to effect a prompt and valid transfer of the interests described above. The Defaulting Party shall be obligated to promptly remove any liens and encumbrances which may exist on such transferred interests. For purposes of this Article 8.4(D), each Party constitutes and appoints each other Party its true and lawful attorney to execute such instruments and make such filings and applications as may be

necessary to make such transfer legally effective and to obtain any necessary consents the Government. Actions under this power of attorney may be taken by any Party individually without the joinder of the others. This power of attorney is irrevocable for the term of this Agreement and is coupled with an interest. If requested, each Party shall execute a form prescribed by the Operating Committee setting forth this power of attorney in more detail. In the event all Government approvals are not timely obtained, the Defaulting Party shall hold its Participating Interest in trust for the non-defaulting Parties who are entitled to receive the Defaulting Party’s Participating Interest. Notwithstanding the terms of Article XIII, in the absence of an agreement among the non-defaulting Parties to the contrary, any transfer to the non-defaulting Parties following a withdrawal pursuant this Article 8.4(D) shall be in proportion to the Participating interests of the non-defaulting Parties. The acceptance by a non-defaulting Party of any portion of a Defaulting Party’s Participating Interest shall no limit any rights or remedies mat the non-defaulting Party has to recover all mounts (including interest) owing under this Agreement by the Defaulting Party.

(E) The non-defaulting Parties shall be entitled to recover from the Defaulting Party all reasonable attorneys’ fees and all other reasonable costs sustained in the collection of amounts owing by the Defaulting Party.

(F) The rights and remedies granted to the non-defaulting Parties an this Agreement shall be cumulative, not exclusive, and shall be in addition to any other rights and remedies that may be available to the non-defaulting Parties. Whether at law, in equity or otherwise. Each right and remedy available to the non-defaulting Parties may be exercised from time to time and so often and in such order as may be considered expedient by the non-defaulting Parties in their sole discretion.

8.5 Survival

The obligations of the Defaulting Party and the rights of the non-defaulting Parties shall survive the surrender of the Contract, abandonment of Joint Operations and termination of this Agreement.

8.6 No Right of Set Off

Each Party acknowledges and accepts that a fundamental principle of this Agreement is that each Party pays its Participating Interest share of all amounts due under this Agreement as and when required. Accordingly, any Party which becomes a Defaulting Party undertakes that, in respect of either any exercise by the non-defaulting Parties of any rights under or the application of any of the provisions of this Article VIII, such Party hereby waives any right to raise by way of set off or invoke as a defense whether in law or equity, any failure by any other Party to pay amounts due and owing under this Agreement or any alleged claim that such Party may have against Operator or any Non-Operator, whether such claim arises under this Agreement or otherwise. Each Party further agrees that the nature and the amount of the remedies granted to the non-defaulting Parties

hereunder are reasonable and appropriate in the circumstances.

Except as otherwise provided in this Article IX or in Article VIII, each Party shall have the right and obligation to own, take in kind and separately dispose of the share of total production available to it from any Exploitation Area pursuant to the Contract and this Agreement in such quantities and in accordance with such procedures as may be set forth in the offtake agreement referred to in Article 9.2 or in the special arrangements for natural gas referred to in Article 9.3. If GNPC is party to the offtake agreement, then the Parties shall endeavour to obtain its agreement to the principles set forth in this Article IX.

9.2 Offtake Agreement for Crude Oil

If crude oil is to be produced from an Exploitation Area, the Parties shall in good faith, and not less than three (3) months prior to first delivery of crude oil, negotiate and conclude the terms of agreements to cover the offtake of crude oil produced under the Contract. GNPC may, if necessary and practicable, also be party to the offtake agreement. This offtake agreement shall, to the extent consistent with the Contract, make provision for:

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

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

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

(D) Elimination of overlifts and underlifts;

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

(F) Distribution to the Parties of available grades, gravities and qualities of Hydrocarbons to ensure, to the extent Parties take delivery of their Entitlements as they accrue, that each Party shall receive in each period Entitlements of grades,

gravities and qualities of Hydrocarbons from each Exploitation Area in which it participates similar to the grades, gravities and qualities of Hydrocarbons received by each other Party from that Exploitation Area in that period.

(G) To the extent that distribution of Entitlements on such basis is impracticable due to availability of facilities and minimum cargo sizes, if applicable, method of making periodic adjustments; and

(H) The option, and the right of the other Parties to sell an Entitlement which a Party fails to nominate for acceptance pursuant to (C) above or of which a Party fails to take delivery, in accordance with applicable agreed procedures provided that such failure either constitutes a breach of Operator’s or Parties’ obligations under the terms of the Contract, or is likely to result in the curtailment or shut-in of production. Such sales shall be made only to the limited extent necessary to avoid disruption in Joint Operations. Operator shall give all Parties as much notice as is practicable of such situation and that a sale option has arisen. Any sale shall be of the unnominated or undelivered Entitlement as the case may be and for reasonable periods of time as are consistent with the minimum needs of the industry and in no event to exceed twelve (12) months. The right of sale shall be revocable at will subject to any prior contractual commitments. Payment terms for production sold under this option shall be established in the offtake agreement.

If an offtake agreement has not been entered into by the date of first delivery of crude oil, the Parties shall be bound by the principles set forth in this Article 9.2 until an offtake agreement has been entered into.

9.3 Separate Agreement for Natural Gas

The Parties recognize that if natural gas is discovered it may be necessary for the Parties to enter into special arrangements for the disposal of the natural gas, which are consistent with the Development Plan and subject to the terms of the Contract.

ARTICLE X — ABANDONMENT

10.1 Abandonment of Wells Drilled as Joint Operations

(A) A decision to plug and abandon any well which has been drilled as a Joint Operation shall require the approval of the Operating Committee.

(B) Should any Party fail to reply within the period prescribed in Article 5.12(A)(1) or Article 5.12(A)(2), whichever is applicable, after delivery of notice of the Operator’s proposal to plug and abandon such well, such Party shall be deemed to have consented to the proposed abandonment.

(C) If the Operating Committee approves a decision to plug and abandon an Exploration Well or Appraisal Well, any Party voting against such decision may propose, within

the time periods allowed by Article 5.13(A), to conduct an alternate Exclusive Operation in the wellbore.

This Article X shall apply mutatis mutandis to the abandonment of an Exclusive Well or any well in which an Exclusive Operation has been conducted (in which event all Parties having the right to conduct further operations in such well shall be notified and have the opportunity to conduct Exclusive Operations in the well in accordance with the provisions of this Article X).

10.3 Abandonment Security

During preparation of a Development Plan, the Parties shall negotiate and agree a security agreement, which shall be completed and executed by all Parties participating in such Development Plan prior to application for an Exploitation Area.

ARTICLE XII — TRANSFER OF INTEREST OR RIGHTS

12.1 Obligations

(A) Subject always to the requirements of the Contract, the transfer of all or part of a Party’s Participating Interest, excepting transfers pursuant to Article VIII or Article XIII, shall be effective only if it satisfies the terms and conditions of this Article XII.

(B) Except in the case of a Party transferring all of its Participating interest or in the case of a transfer by a Party whose initial Participating Interest is less than five per cent (5%), no transfer shall be made by any Party which results in the transferor or the transferee holding a Participating Interest of less than five percent (5%) or holding any interest other than a Participating Interest in the Contract, the Contract Area (or a part of the Contract Area) and this Agreement.

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

(D) The transferee shall have no rights in and under the Contract, the Contract Area, and this Agreement unless and until it obtains any necessary approval of the Government and expressly undertakes in an instrument satisfactory to the other Parties to perform the obligations of the transferor under the Contract and this Agreement in respect of the Participating Interest being transferred and furnishes any guarantees required by the Government.

(E) A transferee other than an Affiliate and/or a Party shall have no rights in and under the Contract, the Contract Area, or this Agreement unless each Party has consented in writing to such transfer, which consent shall not be unreasonably refused or delayed and shall be refused only if such transferee fails to establish to the satisfaction of each Party its capability to perform its obligations under the Contract and this Agreement.

(F) Nothing contained in this Article XII shall prevent a Party from mortgaging, pledging, charging or otherwise encumbering all or part of its interest in the Contract Area and in and under this Agreement for the purpose of security relating to finance provided that:

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

(2) the encumbrance shall be subject to any necessary approval of the Government and be expressly subordinated to the rights of the other Parties under this Agreement; and

(3) such Party shall ensure that any such mortgage, edge, charge or encumbrance shall be expressed to be without prejudice to the provisions of this Agreement.

(G) With the sole exceptions of

(a) the currency proposed transfer by Kosmos of a twenty per cent (20%) Participating Interest to Anadarko WCTP Company and

(b) the anticipated transfers during 2006 by Tullow of a Participating Interest to an as yet unidentified third party and to Tullow of a Participating Interest from an existing Party

any intended transfers of all or a portion of Participating Interest, whether directly or indirectly by assignment, merger, consolidation, or sale of stock or shares or other conveyance, other than to an Affiliate, shall be subject to the following procedure:

(1) Once the intended transferor Party and a proposed transferee (being a third party or a Party) have negotiated the final terms and conditions of an intended transfer, such final terms and conditions shall be disclosed in reasonable detail to all Parties in a notice from the transferor. Each Party shall have the right to acquire the Participating Interest from the transferor on the same terms and conditions agreed to by the proposed transferee if, within thirty (30) Days of transferor’s notice, such Party delivers to all other Parties a counter-notification that it accepts the agreed upon terms and conditions of the transfer without reservations or conditions. If no Party delivers such counter-notification, the intended transfer to the proposed transferee may be made, subject to the other provisions of this Article XII under terms and conditions no more favorable to the transferee than those set forth in the notice to the Parties, provided that the transfer shall be concluded within one hundred eighty (180) Days from the date of the notice plus such reasonable additional period as nay be required to secure governmental approvals.

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

(3) In the event that a Party’s proposed transfer of part or all of its Participating Interest involve consideration other than cash or involves other properties

included in a wider transaction (package deal) then the Participating interest (or part thereof) shall be allocated a reasonable and justifiable cash value by the transferor in any notification to the other Parties. Such other Parities may satisfy the requirements of this Article 12.1(G) by agreeing to pay such cash value in lieu of the consideration payable in the third-party offer.

ARTICLE XIV — RELATIONSHIP OF PARTIES AND TAX

14.1 Relationship of Parties

The rights, duties, obligations and liabilities of the Parties under this Agreement shall be individual, not joint or collective.

The Parties intend that all income and all tax benefits (including, but not limited to, deductions, depreciation, credits and capitalization) with respect to the expenditures made by the Parties hereunder will be allocated by the Government tax authorities to the Parties based on the share of each tax item actually received or borne by each Party. If such allocation is not accomplished due to the application of the laws and regulations of the Government or other Government action, the Parties shall attempt to adopt mutually agreeable arrangements that will allow the Parties to achieve the financial results intended. Operator shall provide each Party, in a timely manner and at such Party’s sole expense, with such information with respect to Joint Operations as such Party may reasonably request for preparation of its tax returns or responding to any audit or other tax proceeding.

Operator is authorised and directed to execute and file for each U.S. Party such evidence or this election as may be required by the Internal Revenue Service, including specifically, but not by way of limitation, all of the returns, statements, and the data required by United States Treasury Regulations Sections 1.761-2 and 1.6031(a)-1(b)(5), and shall provide a copy thereof to each U.S. Party.

(B) No Party shall give any notice or take any other action inconsistent with the election made above. If any income tax laws of any state or other political subdivision of the United States or any future income tax laws of the United States or any such political subdivision contain provisions similar to those in Subchapter “K”, Chapter1, Subtitle “A” of the Code, under which an election similar to that provided by Section 761(a) of the Code is permitted, each U.S. Party shall make such elections as may be permitted or required by such laws. In making the foregoing election, each U.S. Party states that the income derived by it from operations under this Agreement can be adequately determined without the computation of partnership taxable income.

(C) For the purposes of this Article XIV, “U.S. Party” shall mean any Party which is subject to the income tax law of the United States in respect of operations under this Agreement.

Operator shall make a reasonable effort to reply to the report in writing as soon as possible and in any event no later than ninety (90) Day after receipt of the report. Should the Non-Operators consider that the report or reply requires further investigation of any item therein, the Non-Operators shall have the right to conduct further investigation in relation to such matter notwithstanding the provisions of Sections 1.7 and 1.8.1 that the period of twenty-four (24) months may have expired. However, conducting such further investigation shall not extend the twenty-four (24) month period for taking written exception to and making a claim upon the Operator for all discrepancies disclosed by said audit. Such further investigations shall be commenced within thirty (30) Days and be concluded within sixty (60) Days after the receipt of such report or reply, as the case may be.
