CONFIDENTIAL

effect a Change of Parent Board Recommendation would constitute a breach of its fiduciary duties to the shareholders of Parent under applicable Law; provided that (A) Parent has provided Buyer three (3) Business Days’ prior written notice advising Buyer that it intends to effect a Change of Parent Board Recommendation and specifying, in reasonable detail, the reasons for the Change of Parent Board Recommendation and (B) during such three (3) Business Day period, if requested by Buyer, Parent engages in good faith negotiations with Buyer to amend the terms of this Agreement in a manner that obviates the need for the Change of Parent Board Recommendation.

(g) Notwithstanding any Change of Parent Board Recommendation pursuant to Section 5.5(e), unless this Agreement is terminated pursuant to its terms, this Agreement (and the transactions contemplated under this Agreement) shall be submitted to the shareholders of Parent for the purposes of obtaining the Parent Shareholder Approval, and nothing contained in this in Section 5.5 (including any rights of Parent to take certain actions pursuant to this Section 5.5) shall be deemed to relieve Parent of such obligation.

(h) The parties acknowledge that the agreements contained in Section 5.5(d), Section 8.2(b) and Section 8.2(c) are an integral part of this Agreement and the transactions contemplated hereby and, solely for the purpose of establishing the basis for the amount thereof and without in any way increasing the amount of the Parent Termination Fee or expanding the circumstances in which the Parent Termination Fee is to be paid, the parties acknowledge and agree that the Parent Termination Fee constitutes liquidated damages and not a penalty, and that the parties would not have entered into this Agreement without the agreements in Section 5.5(d), Section 8.2(b), Section 8.2(c) and this Section 5.5(h). The parties expressly acknowledge and agree that, in light of the difficulty of accurately determining actual damages with respect to the foregoing upon any such termination of this Agreement under circumstances in which the Parent Termination Fee is payable pursuant to Section 5.5(d), Section 8.2(b) or Section 8.2(c), the right to such payment: (A) constitutes a reasonable estimate of the damages that will be suffered by Buyer by reason of any such termination of this Agreement, and (B) shall be in full and complete satisfaction of any and all damages arising as a result of any such termination of this Agreement.

Section 5.6 Consents.

(a) Seller and Parent shall, at their cost, use their respective commercially reasonable efforts to fulfill all of the conditions set out in Section 6.1(b), Section 6.1(d) Section 6.1(f), Section 6.2(d) and Section 6.2(e) as soon as possible after the Execution Date and in any event by no later than the Outside Date (or, in the case of Parent Shareholder Approval, by no later than the Shareholder Approval End Date), including:

Seller and Buyer shall consult with each other and attempt in good faith to resolve any issues arising as a result of such Tax Returns and, if they are unable to do so, the disputed items shall be resolved (within a reasonable time, taking into account the deadline for filing such Tax Return) by an independent internationally recognized accounting firm acceptable to Buyer and Seller. Upon resolution of all such items, the relevant Tax Return shall be timely filed on that basis; provided, however, that if after using reasonable best efforts, the parties are unable to resolve the matter in dispute before any Tax Return that is the subject of a disagreement is due, such Tax Return may be filed as prepared (or caused to be prepared) by Seller, subject to adjustment or amendment upon resolution, and the making of any payments necessary to give effect to the resolution.

CONFIDENTIAL

shall not resolve such Tax Contest, to the extent such Tax Contest relates to Tax items that directly impact Post-Effective Date Period Taxes, without Buyer’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed. If Seller declines to control such Tax Contest, then Buyer shall have the right to control the conduct of such Tax Contest; provided, however, that Buyer shall not resolve such Tax Contest without Seller’s written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Each party shall bear its own costs for participating in such Tax Contest including reasonable attorneys’ and accountants’ fees and disbursements.

(d) From and after the Closing Date, Seller, in its sole discretion, may prepare, or cause to be prepared, a draft amended Tax Return or draft claim for refund for the Acquired Companies relating to a Pre Effective Date Period.

Section 9.3 Tax Records and Cooperation. Seller and Buyer shall (a) each provide the other, and Buyer shall, from Closing, cause the Acquired Companies to provide to Seller, such assistance as may be reasonably requested by any of them in connection with the preparation of any Tax Return, audit or other examination by any Governmental Authority or Proceeding relating to liability for Taxes, including, as and when requested by the other, the preparation by employees or agents of Buyer or Seller, as the case may be, who have access to or possession of the accounting entries and supporting documents necessary to prepare a Tax Return, of a draft of all of any part of a Tax Return and for delivery of such Tax Return to the other for review and filing, (b) each retain and provide the other on request, at the expense of the requesting party, with any material records or information which may be relevant to such Tax Return, audit, Proceeding or determination, and (c) each provide the other with any amount shown as due on any Tax Return of the other, as well as supporting calculations for such amount, for any period.

Section 9.5 Withholding Taxes. The payment of the Purchase Price from Buyer to Seller under this Agreement shall be made free and clear of, and without deduction or withholding for, any Taxes, unless such deduction or withholding is required by applicable Law. If Buyer is required by applicable Law to deduct or withhold Taxes from such payments, then Buyer shall pay, in addition to the amount otherwise due to Seller hereunder, such additional amount as is necessary to ensure that the net amount actually paid to Seller will equal the full amount Seller would have received had no such deduction or withholding been required.

Section 9.6 Certain Tax Elections. Buyer shall not make any Tax election under the Internal Revenue Code of 1986, as amended (“Code”), with respect to the purchase of the Subject Shares pursuant to this Agreement which would cause such purchase to be treated as an asset purchase for Tax purposes, including any entity classification election or an election under Section 338 of the Code.

Section 9.7 Claim Procedure. To the extent not inconsistent with the provisions of Section 9.2, the following procedures shall apply in the case of any claim of Losses for Taxes.

(a) If either Seller or Buyer, as the case may be, (“Claimant”) seeks recovery under this Article 9 in response to a claim or Proceeding by another Person not a party to this Agreement (a “Third Party Tax Claim”), then Claimant shall provide written notice to the “Other Party” (which shall be Buyer (if Claimant is Seller) or Seller (if Claimant is Buyer)) complying with the requirements of Section 9.7(d) within ten (10) Business Days after Claimant has received notice or otherwise learns of the assertion of such Third Party Tax Claim; provided, however, that no delay or deficiency on the part of Claimant in so notifying the Other Party shall relieve the Other Party of any liability under this Agreement except to the extent such delay or deficiency prejudices or otherwise adversely affects the rights of the Other Party with respect thereto.

(b) In the event of a Third Party Tax Claim, Claimant shall use its commercially reasonable efforts (at the cost and expense of the Other Party) to allow the Other Party to participate in the defense thereof and, if the Other Party so chooses, assume at any time control of the defense thereof with counsel reasonably satisfactory to Claimant by giving to Claimant written notice of its intention to assume control of the defense of such Third Party Tax Claim; provided, however, that Claimant may participate in the defense of such Third Party Tax Claim with its own counsel at its own expense.

(c) The Other Party shall not agree to any settlement of, or consent to the entry of any judgment (other than a judgment of dismissal on the merits without costs) arising from, any such Third Party Tax Claim without the prior written consent of Claimant; provided, however, that the consent of Claimant shall not be required if the Other Party agrees in writing to pay any amounts payable pursuant to such settlement or any judgment and such settlement or judgment includes a full, complete and unconditional release of Claimant from further liability. Claimant shall not agree to any settlement of, or the entry of any judgment (other than a judgment of dismissal on the merits without costs) arising from, any such Third Party Tax Claim without the prior written consent of the Other Party.

CONFIDENTIAL

(d) If Claimant becomes aware of any claim or any matter or circumstance which could give rise to a right to seek recovery under this Article 9, Claimant shall, subject to any applicable confidentiality obligations provide written notice to the Other Party setting out (i) a description, and if known, the estimated amount of Losses incurred or reasonably expected to be incurred by Claimant, (ii) a reasonable explanation of the basis for such claim to the extent of the facts then known by Claimant and (iii) a demand for payment of those Losses.

(b) In the event of a Third Party Claim, Buyer shall use its commercially reasonable efforts (at the cost and expense of Seller) to allow Seller to participate in the defense thereof and, if Seller so chooses, assume at any time control of the defense thereof with counsel reasonably satisfactory to Buyer by giving to Buyer written notice of its intention to assume control of the defense of such Third Party Claim; provided, however, that Buyer may participate in the defense of such Third Party Claim with its own counsel at its own expense.

8.	No Duplication

The Buyer shall not be entitled to recover damages or obtain indemnity more than once in respect of any one shortfall, damage, deficiency, breach or other set of circumstances which gives rise to one or more claims for breach of the Seller Warranties.

FORM OF ESCROW AGREEMENT

[Attached]

CONFIDENTIAL

ESCROW AGREEMENT

THIS ESCROW AGREEMENT (this “Agreement”), dated June , 2012 (“Execution Date”), is by and among PT Pertamina (Persero), a state-owned limited liability company duly organized and existing under and by virtue of the Laws of the Republic of Indonesia (“Buyer”), HNR Energia B.V., a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) under the Laws of Curaçao (“Seller”), and JPMorgan Chase Bank, N.A., a national banking association established under the laws of the State of New York (“Escrow Agent”). Seller and Buyer are referred to herein sometimes individually as a “Party” and collectively as the “Parties”.

Recitals:

Harvest Natural Resources, Inc., Seller and Buyer entered into a Share Purchase Agreement, dated June , 2012 (the “Purchase Agreement”), under which Buyer agreed to purchase from Seller the Subject Shares.

Under Section 5.7 of the Purchase Agreement, Seller and Buyer agreed to execute and deliver this Agreement and for Buyer to make the Escrow Deposit (as defined below).

Agreement:

NOW THEREFORE, in consideration of the foregoing and of the mutual covenants hereinafter set forth, the Parties and the Escrow Agent agree as follows:

1. Appointment. The Parties hereby appoint Escrow Agent as their escrow agent for the purposes set forth herein, and Escrow Agent hereby accepts such appointment under the terms and conditions set forth herein.

2. Fund. Buyer agrees to deposit with Escrow Agent the sum of $108,750,000.00 (“Escrow Deposit”). Escrow Agent shall hold the Escrow Deposit and shall invest and reinvest the Escrow Deposit and the proceeds thereof (together, the “Fund”) in a JPMorgan Money Market Deposit Account (“MMDA”), or a successor or similar investment offered by Escrow Agent. MMDA have rates of compensation that may vary from time to time based upon market conditions. The Parties recognize and agree that instructions to make any other investment (“Alternative Investment”), must be in writing and executed by an Authorized Representative (as defined in Section 3 below), and shall specify the type and identity of the investments to be purchased and/or sold. Escrow Agent is hereby authorized to execute purchases and sales of any investments through the facilities of its own trading or capital markets operations or those of any affiliated entity. Escrow Agent or any of its affiliates may receive reasonable compensation with respect to any Alternative Investment directed hereunder including without limitation charging any reasonable applicable agency fee in connection with each transaction. Escrow Agent will not provide supervision, recommendations or advice relating to either the investment of moneys held in the Fund or the purchase, sale, retention or other disposition of any investment described herein, and Escrow Agent shall not have any liability for any loss in an investment made pursuant to the terms of this Agreement except for losses arising out of Escrow Agent’s gross

CONFIDENTIAL

negligence or willful misconduct, or its failure to act in accordance with any joint written investment instruction received hereunder from the Parties as provided in this Section 2. Market values, exchange rates and other valuation information (including without limitation, market value, current value or notional value) of any Alternative Investment furnished in any report or statement may be obtained from third party sources and is furnished for the exclusive use of the Parties. Escrow Agent has no responsibility whatsoever to determine the market or other value of any Alternative Investment and makes no representation or warranty, express or implied, as to the accuracy of any such valuations or that any values necessarily reflect the proceeds that may be received on the sale of an Alternative Investment. Escrow Agent shall not have any liability for any loss sustained as a result of any investment made pursuant to and in accordance with the terms of this Agreement or as a result of any liquidation of any investment prior to its maturity or for the failure of an Authorized Representative of the Parties to give Escrow Agent instructions to invest or reinvest the Fund. Escrow Agent shall have the right to liquidate any investments held in order to provide funds necessary to make required payments under this Agreement. All interest or other income earned under this Agreement shall be allocated in accordance with this Agreement and reported by Escrow Agent to the IRS, or any other taxing authority, on IRS Form 1099 or 1042S (or other appropriate form) as income earned from the Escrow Deposit by Buyer or Seller, as applicable, upon distribution of the Fund. Escrow Agent shall withhold any taxes it deems appropriate in the absence of proper tax documentation or as required by law, and shall remit such taxes to the appropriate authorities. Except as provided in this Agreement, the Parties represent to the Escrow Agent that no other tax reporting obligation is required of the Escrow Agent solely with respect to the Escrow Deposit.

Receipt of the Escrow Deposit and investment and reinvestment of the Fund shall be confirmed to Buyer and Seller by the Escrow Agent as soon as practicable by monthly account statement, and any discrepancies in any such account statement shall be noted by Buyer and Seller to the Escrow Agent within thirty (30) days after receipt thereof.

(d) As used in this Section 3, “Business Day” shall mean any day other than a Saturday, Sunday or any other day on which Escrow Agent located at the notice address set forth below is authorized or required by law or executive order to remain closed. The Parties acknowledge that the security procedures set forth in this Section 3 are commercially reasonable. Upon delivery of the Fund by Escrow Agent, this Agreement shall terminate, subject to the provisions of Section 6.

4. Escrow Agent. Escrow Agent shall have only those duties as are specifically and expressly provided herein, which shall be deemed purely ministerial in nature, and no other duties shall be implied. Escrow Agent has no knowledge of, nor any requirement to comply with, the terms and conditions of any other agreement, instrument or document (other than the joint written instructions described herein) between the Parties, nor shall Escrow Agent be required to determine if any Party has complied with any other agreement. Notwithstanding the terms of any other agreement between the Parties, the terms and conditions of this Agreement shall control to the extent of such conflict between the Escrow Agent and the Parties; provided, however, that the terms and conditions of the Purchase Agreement shall control as between the Parties. Escrow Agent may conclusively rely upon any written notice, document, instruction or request furnished to it hereunder and reasonably believed by it in good faith to be genuine and to have been signed or presented by the proper Authorized Representative(s), as applicable, without inquiry and without requiring substantiating evidence of any kind and Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or content of any such document, notice, instruction or request. Escrow Agent shall not be liable for any action taken, suffered or omitted to be taken by it in good faith except to the extent that Escrow Agent’s gross negligence or willful misconduct was the cause of any direct loss to either Party. Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through its affiliates or agents. In the event Escrow Agent receives instructions, claims or demands from any Party hereto which in its reasonable opinion conflict with any of the provisions of this Agreement, or if Escrow Agent receives conflicting instructions from the Parties, Escrow Agent shall be entitled either to (a) refrain from taking any action associated therewith and its sole obligation thereafter shall be to keep safely all property held in escrow until it shall be given a joint written direction executed by Authorized Representatives of the Parties which eliminates such conflict or by a final court order or (b) file an action in interpleader. Escrow Agent shall have no duty to solicit any payments which may be due it or the Fund, including, without limitation, the Escrow Deposit nor shall the Escrow Agent have any duty or obligation to confirm or verify the accuracy or correctness of any amounts deposited with it hereunder. Anything in this Agreement to the contrary notwithstanding, in no event shall Escrow Agent or the Parties be liable hereunder for special, incidental, punitive, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits) (collectively, “Consequential Damages”), even if Escrow Agent or the Parties, as applicable, have been advised of the likelihood of such loss or

CONFIDENTIAL

damage and regardless of the form of action; provided, however, that nothing contained in the preceding sentence shall excuse the Parties from their obligations to indemnify the Escrow Agent for any Consequential Damages paid by the Escrow Agent to a third-party and as otherwise set forth in Section 7 of this Agreement.

5. Resignation; Succession. Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving thirty (30) days advance notice in writing of such resignation to the Parties. Escrow Agent’s sole responsibility after such thirty (30) day notice period expires shall be to hold the Fund (without any obligation to reinvest the same) and to deliver the same to a designated substitute escrow agent, if any, appointed by the Parties, or such other person designated by the Parties, or in accordance with the directions of a final order or judgment of a court of competent jurisdiction, at which time of delivery, Escrow Agent’s obligations hereunder shall cease and terminate. If prior to the effective resignation date, the Parties have failed to appoint a successor escrow agent, or to instruct the Escrow Agent to deliver the Fund to another person as provided above, at any time on or after the effective resignation date, Escrow Agent either (a) may interplead the Fund with a court of competent jurisdiction; or (b) appoint a successor escrow agent of it own choice. Any appointment of a successor escrow agent shall be binding upon the Parties and no appointed successor escrow agent shall be deemed to be an agent of Escrow Agent. Escrow Agent shall deliver the Fund to any appointed successor escrow agent, at which time Escrow Agent’s obligations under this Agreement shall cease and terminate. Any entity into which Escrow Agent may be merged or converted or with which it may be consolidated, or any entity to which all or substantially all the escrow business may be transferred, shall be the “Escrow Agent” under this Agreement without further act.

6. Compensation. The Parties agree jointly and severally to pay Escrow Agent upon execution of this Agreement and from time to time thereafter reasonable compensation for the services to be rendered hereunder, which unless otherwise agreed in writing, shall be as described in Schedule 2. Absent joint written instructions from the Parties to the contrary, all such compensation is to be deducted by the Escrow Agent directly from the Fund. The obligations contained in this Section 6 shall survive the termination of this Agreement and the resignation, replacement or removal of the Escrow Agent. The Parties hereby grant Escrow Agent a lien on, right of set-off against and security interest in the Fund for the payment of any claim for fees, expenses and amounts due to Escrow Agent under this Section 6. As between the Parties only, any amounts due to the Escrow Agent pursuant to this Section 6 shall be allocated 50% to Seller and 50% to Buyer.

7. Indemnification and Reimbursement. The Parties agree jointly and severally to indemnify, defend, hold harmless, pay or reimburse Escrow Agent and its affiliates and their respective successors, assigns, directors, agents and employees (the “Indemnitees”) from and against any and all losses, damages, claims, liabilities, penalties, judgments, settlements, litigation, investigations, reasonable and documented out of pocket expenses (including, without limitation, the reasonable fees and expenses of outside counsel and experts and their staffs and all reasonable expense of document location, duplication and shipment) (collectively “Losses”), arising out of or in connection with (a) Escrow Agent’s performance of this Agreement, except to the extent that such Losses are determined by a court of competent jurisdiction through a final order to have been caused by the gross negligence, willful misconduct, or bad faith of such

CONFIDENTIAL

Indemnitee; and (b) Escrow Agent’s following any joint (or singular, but only if expressly permitted hereunder) instructions or directions, from the Parties received in accordance with this Agreement. The obligations set forth in this Section 7 shall survive the resignation, replacement or removal of Escrow Agent or the termination of this Agreement, and as between the Parties, any liability pursuant to this Section 7 shall be allocated 50% to Seller and 50% to Buyer.

8. Notices. All communications hereunder shall be in writing or set forth in a PDF attached to an email, and all instructions from a Party or the Parties to the Escrow Agent shall be executed by an Authorized Representative, and shall be delivered in accordance with the terms of this Agreement by facsimile, email or overnight courier only to the appropriate fax number, email address, or notice address set forth for each party as follows:

9. Compliance with Court Orders. In the event that any of the Fund shall be attached, garnished, levied upon, or otherwise be subject to any court order, or the delivery thereof shall be stayed or enjoined by an order of a court, Escrow Agent is hereby expressly authorized, in its reasonable discretion, to obey and comply with all such orders so entered or issued, which it is advised by legal counsel of its own choosing is binding upon it, whether with or without jurisdiction, and in the event that Escrow Agent obeys or complies with any such order it shall not be liable to any of the Parties hereto or to any other person by reason of such compliance notwithstanding such order be subsequently reversed, modified, annulled, set aside or vacated.

10. Miscellaneous. The provisions of this Agreement may be waived, altered, amended or supplemented only by a writing signed by Escrow Agent and the Parties. Neither this Agreement nor any right or interest hereunder may be assigned by Escrow Agent or by any Party, except as provided in Section 5, without the prior consent of Escrow Agent and the Parties. This Agreement shall be governed by and construed under the laws of the State of New York. Each Party and Escrow Agent irrevocably waives any objection on the grounds of venue, forum non-conveniens or any similar grounds and irrevocably consents to service of process by mail or in any other manner permitted by applicable law and consents to the jurisdiction of the courts located in the State of New York. To the extent that in any jurisdiction either Party or Escrow Agent may now or hereafter be entitled to claim for itself or its assets, immunity from suit, execution, attachment (before or after judgment) or other legal process, such Party or Escrow Agent shall not claim, and hereby irrevocably waives, such immunity. Escrow Agent and the Parties further hereby waive any right to a trial by jury with respect to any lawsuit or judicial proceeding arising or relating to this Agreement. No party to this Agreement is liable to any

CONFIDENTIAL

other party for losses due to, or if it is unable to perform its obligations under the terms of this Agreement because of, acts of God, fire, war, terrorism, floods, strikes, electrical outages, equipment or transmission failure, or other causes reasonably beyond its control. This Agreement and any joint instructions from the Parties, may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument or instruction, as applicable. All signatures of the parties to this Agreement may be transmitted by facsimile, and such facsimile will, for all purposes, be deemed to be the original signature of such party whose signature it reproduces, and will be binding upon such party. If any provision of this Agreement is determined to be prohibited or unenforceable by reason of any applicable law of a jurisdiction, then such provision shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions thereof, and any such prohibition or unenforceability in such jurisdiction shall not invalidate or render unenforceable such provisions in any other jurisdiction. The Parties represent, warrant and covenant that each document, notice, instruction or request provided by such Party to Escrow Agent shall comply with applicable laws and regulations. Except as expressly provided in Section 7 above, nothing in this Agreement, whether express or implied, shall be construed to give to any person or entity other than Escrow Agent and the Parties any legal or equitable right, remedy, interest or claim under or in respect of the Fund or this Agreement.
