FIRST: BACKGROUND

1) That Pluspetrol, Geopark, IPR and Manas are the current participants of the Special Operation Agreement for Hydrocarbon Deposit Exploration and Exploitation, Tranquilo Block, XII Region of Magallanes and Chilean Antarctic, executed with the Chilean State, hereinafter referred to as the “CEOP”, with the following participation percentages: 20% for IPR, 20% for Manas, 30% for Pluspetrol and 30% for Geopark. With respect to the CEOP, the Contracting Participants place on the record the following: 1.1) That by means of the public instrument executed in presence of the Public Notary of Santiago, Mr. Raúl Iván Perry Pefaur, dated the twenty-ninth of April of two thousand eight, the Chilean State, as one party, and, as the other party, the Contractor, formed by the participants IPR and MANAS, with 50% participation each, executed the CEOP. 1.2) That by means of the public instrument executed in presence of the Public Notary of Santiago, Mrs. Antonieta Mendoza Escalas, dated the nineteenth of January of two thousand nine, IPR and Manas transferred part of their rights in the CEOP to Geopark and to Pluspetrol, with the Contractor Participants then being IPR, Manas, Geopark and Pluspetrol, each one with the following participation percentages: 30% for Geopark, 30% for Pluspetrol, 20% for IPR and 20% for Manas. 1.3) That the Contractor Participants designated Geopark as Operator of the CEOP, with authority and exclusive right to carry out the oil operations within the area of the CEOP.

2) That it is the intention of the appearing parties to modify the participation in the CEOP for the purpose of incorporating Wintershall, Methanex and IFC to it, with IPR and Manas transferring all their rights, interests and obligations in the CEOP, as well as to regulate their relations and financing contributions while the approval of the public authority referred to in the following paragraph is pending.

2

3) That even if the IFC party does not appear in the present Framework Agreement, it is the intention and the interest of the appearing parties that IFC be incorporated as participating in the CEOP by which motive Geopark, with the approval of the other appearing parties, assumes the obligation to cede and transfer to it, under the terms and conditions established in this Framework Agreement, 12.5% of the rights in the CEOP. Thus IFC’s willingness to be incorporated in the CEOP is established as IFC accepts the request for approval as referred to in the above clause 2.

4) That in compliance with the provisions of article 14.1 of the CEOP, prior written approval of the Mining Ministry is required for the transfer of all or part of the rights, interests and obligations in the CEOP by a Contractor Participant.

5) That the terms used in this Agreement and that are not expressly defined, will have the meaning that is given them in the CEOP.

SECOND: PURPOSE

1) That, once the provisions of clauses 3.1 and 3.3 of this instrument are fulfilled, the new participation percentages of the CEOP will be the following: 25% for Pluspetrol, 25% for Geopark, 25% for Wintershall, 12.5% for Methanex and 12.5% for IFC. As a consequence of the above, IPR and Manas will transfer all their rights, interests and obligations to the CEOP.

2) For the purpose of achieving these new participations and for IPR and Manas to leave off being Contractor Participants in the CEOP, the appearing parties are obliged to present to the Mining Ministry the request for approval of the transfer of rights, interests and obligations in the CEOP and to formalize the corresponding transfer agreements once the Mining Ministry grants its approval.

3) While the approval by the Mining Ministry is pending, considering the contents of number 2 of the first clause, the appearing parties agree to assume in the form considered in the fourth clause the disbursements necessary for the financing of the oil operations necessary to comply with the provisions of the CEOP.

4) To regulate the effects that a possible refusal by the Mining Ministry to approve the transfer of rights by IPR and Manas will have.

THIRD: NEW PARTICIPATION PERCENTAGES IN THE CEOP

1) In order to achieve the participations indicated in number one of the second clause, Pluspetrol, Geopark, IPR and Manas are required to assign and transfer all or part of their rights, interests and obligations in the CEOP to Wintershall, Methanex and IFC, as follows: (i) Pluspetrol will transfer 5% of its rights, interests and obligations in the CEOP to Wintershall, in this way reducing to 25% its participation in the aforementioned CEOP. (ii) Geopark will transfer 5% of its rights, interests and obligations in the CEOP to IFC, thus reducing to 25% its participation in the aforementioned CEOP. (iii) Manas will transfer 12.5% of its rights, interests and obligations in the CEOP to Methanex and 7.5% of its rights, interests and obligations in the CEOP to IFC, which results in the transfer of all its rights, no longer being a Contractor Participant of the CEOP.

3) The corresponding transfers of rights, interests and obligations in the CEOP to will be carried out as soon as the Mining Ministry grants the approval to these transfers, in accordance with the provisions of number 2 of the fourth clause.

4) In this act, through separate instruments, the appearing parties sign the letter addressed to the Mining Ministry requesting approval of the transfer of rights, interests and obligations in the “Special Operation Agreement for the Hydrocarbon Deposit Exploration and Exploitation of the Tranquilo Block, Region XII”, referring to the new participations in the CEOP, entrusting Geopark with its presentation and processing before the public authority.

FOURTH: OBLIGATIONS OF THE APPEARING PARTIES.

The appearing parties undertake the following obligations:

1) Obligation to agree to the financing of the oil operations while the approval by the Mining Ministry is pending, hereinafter “Disbursements during the intermediate stage”.

1.1) From the date of the signing of this agreement, during the entire time that the approval by the Mining Ministry is pending regarding the request for transfer of rights, and until the date in which the corresponding public instruments and acceptance of the rights are signed –the “Intermediate Stage”- Pluspetrol, Geopark – for itself and for the percentage of the rights to be ceded to IFC -, Wintershall, Methanex and IFC agree and promise to agree monthly on the financing of all the expenses and investments generated by the oil operations of the CEOP, which cannot exceed the sum of US$15,000,000 (fifteen million dollars of the United States of America) for a period of five months counting from the date of this agreement. The percentage of the contribution of each of the aforementioned companies during the Intermediate Stage will be the following: i) Pluspetrol, 30%; ii) Geopark, 37.5% – for itself and for the percentage of the rights to be ceded to IFC -; iii) Wintershall, 20%; and iv) Methanex, 12.5% .

1.2) Considering that all the financing of the oil operations will be carried out with contributions from the companies Pluspetrol, Geopark – for itself and for the percentage of the rights to be ceded to IFC -, Wintershall, Methanex, and IFC, excluding IPR and Manas from them, and that the financial contribution that corresponds to these last two companies according to the CEOP is 20% for each one, that is, 40% of the total financing, in their character of current participants of the CEOP, which will be assumed by Wintershall, Methanex and Geopark – for itself and for the percentage of the rights to be ceded to IFC - in the Intermediate Stage, IPR and Manas agree to assume the obligations that are set forth in the following clause, in order to respond for the return of 20% that corresponds to each one in the contributions, in the event that the Mining Ministry does not approve the transfer.

4

1.3) For the purpose of materializing the contributions, Pluspetrol, Geopark – for itself and for the percentage of the rights to be ceded to IFC -, Wintershall, Methanex, and IFC agree to make available and to transfer the funds and financial resources in the percentages referred to in number 1.1 of this clause, to the joint bank account of the Tranquilo Block whose owner is Geopark as operator of the CEOP. For these purposes, Geopark will send to each of the contributors a request for funds –called “cash call”- with instructions on the amount to be transferred by each one, the currency of the contribution, the due date of the transfer, the bank account information and any other background information necessary to be able to place the required funds at the disposal of the operator in a timely manner. The cash call with the instructions must be done in writing or through electronic means and set to Wintershall, Pluspetrol, Methanex and Geopark – for itself and for the percentage of the rights to be ceded to IFC -, at least 15 days in advance of the disbursement. All the amounts of funds must be exempt from bank costs and commissions.

1.4) In case of non-compliance by any of the Parties of its commitments to make the contributions during the Intermediate Stage stipulated in the Fourth Clause 1.1, the non-complying party will only have the right to receive, while the situation of non-compliance persists, the proportional part of the participation by which it has effectively paid and, in addition, the owed sums will accrue interest equal to the LIBOR plus 3% calculated at six months. The complying parties will have the option but not the obligation to agree with financing the non-complying party and, in case that one or more parties through common accord makes use of this option, these parties will accrue ownership of the corresponding right from the non-complying party.

2) Obligation to transfer the rights in the CEOP after the approval by the Mining Ministry

2.1) The appearing parties are required to sign the public instrument(s) of transfer of rights, interests and obligations in the CEOP, and to carry out all the acts and to perform all the procedures necessary for and conducive to formalizing the new participations in the CEOP, under the terms set forth in the third clause. The corresponding transfer of rights, interests and obligations in the CEOP will be carried out as soon as the Mining Ministry gives its written approval to such assignments, and after acceptance by the assignees of the obligations included in the CEOP, all according to article fourteen thereof.

2.2) The parties recognize the existence of costs prior to the signing of this agreement, which correspond to disbursements 1 to 3 – Request for Provision of Funds or “Cash-calls” 1 to 3- for the total sum of US$2,922,222, called “Past Costs”, which were made in participations other than those agreed in the third clause number 2. The composition of these Past Costs is detailed in Annex I of this agreement, which forms part of this instrument.

2.3) As a consequence of the fact that the contributions to make during the Intermediate Stage under the mechanism established in number one of this clause, as well as those contributions made corresponding to the “Past Costs”, will have been made with participation percentages other than those agreed in clause three of this agreement, the parties agree on the following compensation formula for the corresponding participation transfers: the price of the compensation will be equal to the contributions effectively made during the Intermediate Period plus Past Costs (detailed in Annex I) effectively made minus the contributions resulting from applying the new participation percentages to the amounts of the Intermediate Stage, less the amounts resulting from applying the new participation percentages to Past Costs. The result that this formula presents will be the global price of the transfer of rights of the CEOP.

5

2.4) Due to the fact that the disbursements during the Intermediate Stage are not determinable on the date of signing this agreement, it is agreed that the Operator will make the final calculation of the amount to compensate for the disbursements of the financing mechanisms during the Intermediate Stage, and also for the Past Costs of Annex I. This final calculation or settlement will be done once the authorization for the transfer of rights, interests and obligations in the CEOP is granted by the Mining Ministry and the corresponding signing of the public instruments has been performed. The compensation amount must be deposited in the bank accounts that are indicated by each of the parties for this purpose within ten calendar days of sending the final liquidation. This calculation must be certified by PricewaterhouseCoopers, with the parties having a period of five days counting from the notification of this certification to make any observations. Having transpired that period, and if there are no observations, the parties must make the deposit in the bank accounts indicated by each party. Without prejudice of the above, it is hereby recorded that the expenses to be paid by the Operator during the Intermediate Stage and those that correspond to Past Costs cannot be significantly separated from the costs and expenses reported by the operator in the Annual Budgets and Work Schedules presented to the parties which form part of this instrument as Annex II.

3) The companies Geopark – for itself and for the percentage of the rights to be ceded to IFC -, Pluspetrol, Methanex and Wintershall are required, within the period of sixty days counting from the approval by the Mining Ministry of the request for the transfer of rights, interests and obligations of the CEOP, to sign a Joint Operation Agreement for the CEOP Tranquilo Block –called “JOA”- taking as its base the JOA of the Otway Block.

FIFTH: EFFECTS OF THE REFUSAL OR DENIAL BY THE MINING MINISTRY IN APPROVING THE TRANSFER OF RIGHTS OF THE CEOP

Considering the commitments of pecuniary contributions assumed by Wintershall, Methanex and IFC, even before being owners of the rights, interests and obligations of the CEOP, in which IRP and Manas are not included, and in view of the possibility of refusal or negative decision by the Mining Ministry to the request for approval of transfer of rights, IPR and Manas, as well as IPR Chile LLC and MKD Holdings Inc., in their capacity as sole shareholders of IPR, and Manas Management Services Ltd. and Manas Petroleum Corporation, in their capacity as sole shareholders of Manas, declare and agree that, in case of the refusal or denial by the Mining Ministry to grant the referred authorization, the following effects will be produced, assuming the obligations that are indicated:

1) The funds or financial resources that are contributed by Wintershall, Methanex and Geopark – for itself and for the percentage of the rights to be ceded to IFC - for carrying out the CEOP oil operations based on this agreement, from the date of this instrument and until the negative decision of the Mining Ministry, hereinafter called “the total amount owed”, are required to be returned. The return or refund of the funds must be done within the period of ten days counting from the notification of the rejection by the Mining Ministry of the request for approval of the transfer of rights. In order to comply with this obligation, both IPR and Manas are required to pay the total amount due to Wintershall, Methanex and Geopark – for itself and for the percentage of the rights to be ceded to IFC - in the following proportion: a) IPR: 25% of the amount owed to Wintershall, 15.625% of the amount owed to Methanex and 9.375% of the amount owed to Geopark – for itself and for the percentage of the rights to be ceded to IFC -, totalling in this way 50% of the amount owed; and, b) Manas: 25% of the amount owed to Wintershall, 15.625% of the amount owed to Methanex and 9.375% of the amount owed to Geopark – for itself and for the percentage of the rights to be ceded to IFC -, totalling the remaining 50% of the amount owed, equivalent overall to 40% of the participation in the rights of the CEOP.

6

2) In case that IPR and/or Manas do not return to Wintershall, Methanex and Geopark – for itself and for the percentage of the rights to be ceded to IFC - the total amount owed within the period indicated in the previous paragraph, IPR Chile LLC and MKD Holdings Inc., in their capacity of sole shareholders of IPR, and Manas Management Services Ltd., and Manas Petroleum Corporation, in their capacity as sole shareholders of Manas, are required to assign and transfer the total amount of the corporate rights that they have in IPR Chile Tranquilo Limitada and in Manas Energía Chile Limitada, respectively, to the companies Wintershall, Methanex and Geopark – for itself and for the percentage of the rights to be ceded to IFC -, in the following proportions: a) IPR Chile LLC and MKD Holdings Inc.: 50% of the corporate rights to Wintershall, 31.25% of the corporate rights to Methanex and 18.75% of the corporate rights to Geopark; and, b) 50% of the corporate rights to Wintershall, 25% of the corporate rights to Methanex and 31.25% of the corporate rights to Methanex and 18.75 of the corporate rights to Geopark. In order to ensure compliance with this transfer of rights, the appearing parties that are implicated and the respective shareholders of IPR and Manas sign in this act, in separate instruments, in presence of the same authorizing Notary, public instruments “of transfer of corporate rights and modification of the company IPR” and “of transfer of corporate rights and modification of the company Manas”, subject to the condition precedent consisting of IPR and Manas not complying with the requirement to return the total amount owed that was assumed in number one of this clause. Consequently, after the period of ten days has transpired without IPR and/or Manas having returned that total amount owed, the condition precedent will be understood ipso facto as met and the agreements of transfer and modification of the company will be effective.

3) The obligations that IPR and Manas assume in reference to numbers One and Two of this clause will have an indivisible nature. Consequently, the obligation to return considered in number one above fulfilled by only one of the debtors will not be considered as fulfilled if the other debtor does not return or refund what is owed.

SIXTH: MISCELLANEOUS

1) Any reference to the Mining Ministry that is made in this document is understood as also referring to the Energy Ministry, if applicable, as a consequence of the recent legal creation of the Energy Ministry by Law No. 20,402, published in the Official Journal on three December two thousand nine.
