In connection with the actions and procedures referenced in this Section 6.3 and without limiting the rights and obligations of the immediately preceding sentence, each of HNR, Seller and Buyer shall, and shall cause its Representatives to: (x) promptly and fully inform each other of any written or material oral communication received from or given to any Governmental Authority, (y) permit each other to review any submission required to be made to any Governmental Authority, and (z) consult with each other in advance of any meeting, conference or material discussion required by any Governmental Authority, in each case, to the extent related to this Agreement and the transactions contemplated hereby.

(d) None of HNR, Seller or Buyer shall consent to any voluntary delay of the Closing at the behest of any Governmental Authority without the consent of the other, which consent shall not be unreasonably withheld, delayed or conditioned. Each of Buyer, HNR and Seller shall, subject to the last sentence of Section 6.3(a), use reasonable best efforts to ensure that no action taken by such party or any of its Subsidiaries, including acquiring or making any investment in any corporation, partnership, limited liability company or other business organization or any division or assets thereof, causes a material delay in the satisfaction of the conditions contained in Article VII.

(e) Subject to the last sentence of Section 6.3(a), each of Buyer, HNR and Seller shall give (or shall cause their respective Subsidiaries to give) any notices to Third Parties, and use, and cause their respective Subsidiaries to use, their reasonable best efforts to obtain any Third Party consents (other than the Governmental Approvals) (i) necessary, proper or advisable to consummate the transactions contemplated by this Agreement or (ii) disclosed in the Seller Disclosure Schedule or the Buyer Disclosure Schedule, as applicable.

(f) Each of HNR and Buyer hereby irrevocably waives its rights and obligations pursuant to Section 6.9 of the Securities Purchase Agreement to the extent that such rights and obligations are in conflict with or would otherwise prohibit either HNR or Buyer from entering into this Agreement or the Related Agreements or consummating the Sale of Subject Shares and related transactions contemplated by this Agreement to occur at the Closing. Without limiting the foregoing, each of HNR, Seller and Buyer agrees and acknowledges that the Sale of Subject Shares constitutes a “change of control” under the HVDH Shareholders’ Agreement.

Section 6.4 Access to Information; Consultation; Confidentiality.

(a) From the date of this Agreement to the earlier of the Closing Date or the date, if any, on which this Agreement is terminated pursuant to Section 8.1, Seller will, and will cause the HVDH Companies to, and, in the case of Petrodelta, use reasonable best efforts to provide to Buyer and its authorized Representatives (x) reasonable access during normal business hours in such a manner as not to interfere unreasonably with the operation of any business conducted by any of the Acquired Companies, upon prior written notice to Seller, to their respective

- 44 -

officers, employees, agents, Representatives, properties, books, Tax Returns, Tax correspondence, Tax work papers, Tax advice, correspondence with Taxing Authorities (including any assessments of Tax), contracts and records as Buyer may reasonably request and (y) such financial and operating data of the Acquired Companies as Buyer may reasonably request. Notwithstanding the foregoing, Seller shall not be required to provide access to, or cause HVDH or its Subsidiaries to or, in the case of Petrodelta, use reasonable best efforts to provide access to, or disclose any information or documents which would (in the reasonable judgment of the Seller) (i) constitute a waiver of the attorney-client, attorney work-product or other privilege held by HNR, Petrodelta or any of their respective Subsidiaries, (ii) violate any applicable Laws or (iii) violate any confidentiality obligations of HVDH or any of its Subsidiaries under any existing HVDH Company Material Contract to which HVDH or any of its Subsidiaries is a party; provided, that each party shall use its reasonable best efforts to obtain any required consents and take such other action (such as the entry into a joint defense agreement or other arrangement to avoid loss of attorney client privilege) to permit such access or disclosure.

(b) Without limiting the generality of Seller’s obligations set forth in Section 6.4(a) above,

(i) promptly following the date hereof, and in any event no later than twenty (20) Business Days after the date hereof, Seller shall provide Buyer with (x) all Tax Returns, material Tax correspondence, material Tax work papers (including any material work papers related to accounting for the uncertainty of taxes under International Accounting Standard No. 12 or the equivalent thereof under applicable accounting standards), (to the extent not inconsistent with Section 6.4(a)(i) above), and correspondence with Taxing Authorities (including any assessments of Tax) relating to the HVDH Companies and (y) a schedule of the Tax Representatives of the HVDH Companies with contact information for such Representatives; and

(ii) promptly following the request of the Buyer, and in any event no later than ten (10) Business Days following such a request, Seller shall use its reasonable best efforts to organize a meeting between Buyer and any Tax Representative of the HVDH Companies.

Section 6.5 Acquisition Proposals.

(a) Except as expressly permitted by this Section 6.5, from the date of this Agreement until the Closing Date or, if earlier, the termination of this Agreement in accordance with its terms, HNR will not, nor shall it authorize or permit any of its Subsidiaries, and will use its reasonable best efforts to cause Petrodelta, to, and shall use its reasonable best efforts to cause its and their respective Representatives not to, directly or indirectly (i) initiate, solicit or knowingly encourage or facilitate the making of any Acquisition Proposal or any inquiry, proposal or request for information that may reasonably be expected to lead to an Acquisition Proposal, (ii) other than informing Third Parties of the existence of the provisions contained in this Section 6.5, engage in negotiations or discussions with, or furnish any information concerning any of the Acquired Companies, Seller or HNR to, any Third Party relating to an Acquisition Proposal or any inquiry, proposal or request for information that may reasonably be expected to lead to an Acquisition Proposal or (iii) resolve or agree to do any of the foregoing. HNR shall, and shall

- 45 -

cause its Affiliates and its and their respective Representatives to (i) immediately cease and cause to be terminated all existing discussions or negotiations with any Person conducted heretofore with respect to any Acquisition Proposal, or any inquiry or proposal that may reasonably be expected to lead to an Acquisition Proposal and (ii) promptly cause to be returned or destroyed all confidential information provided by or on behalf of HNR or any of its Affiliates to any such Person.

(b) Notwithstanding anything to the contrary contained in this Agreement, in the event that HNR receives an unsolicited written Acquisition Proposal from a Third Party (which Acquisition Proposal was made after the date of this Agreement and did not result from a breach of this Section 6.5), HNR and the HNR Board Special Committee and their Representatives may, subject to compliance with this Section 6.5(b), engage in negotiations or substantive discussions with, or furnish any information and reasonable access to, any Third Party making such Acquisition Proposal and its Representatives if the HNR Board Special Committee determines in good faith, after consultation with the HNR Board Special Committee’s outside legal and financial advisors, and based on information then available, that such Acquisition Proposal constitutes, or is reasonably likely to result in, a Superior Proposal; provided, that HNR shall give written notice to Buyer after any such determination by the HNR Board Special Committee and prior to taking any of the actions described in this Section 6.5(b) and shall comply with the provisions of Section 6.5(f); and provided, further, that (x) prior to furnishing any material nonpublic information, HNR receives from such Third Party an executed Acceptable Confidentiality Agreement and (y) any such material nonpublic information so furnished has been previously provided or made available to Buyer or is provided or made available to Buyer substantially concurrently with it being so furnished to such Third Party. Other than as provided in Section 6.5(c)(i)(C), Section 6.5(d) or Section 6.5(h), HNR shall not publicly announce the receipt of any Acquisition Proposal or any negotiations or discussions in connection with any Acquisition Proposal or otherwise publicly comment on any Acquisition Proposal.

(c) Except as otherwise provided in the last sentence of this Section 6.5(c) and Section 6.5(d), neither the HNR Board nor any committee thereof (including the HNR Board Special Committee) shall (i) (A) withdraw (or qualify or modify in any manner adverse to Buyer), or publicly propose to withdraw (or so qualify or modify), the HNR Board Recommendations, (B) take any action to exempt any Person (other than Buyer and its Affiliates) from the provisions of Section 203 of the DGCL or any other state takeover statute or the Rights Agreement, (C) fail to publicly reaffirm the HNR Board Recommendations within five (5) Business Days after Buyer so requests in writing (which request may only be made once with respect to any such Acquisition Proposal and each material modification thereto), (D) fail to recommend, in a Solicitation/Recommendation Statement on Schedule 14D-9, against any Acquisition Proposal subject to Regulation 14D under the Exchange Act within ten (10) Business Days after the commencement of such Acquisition Proposal, (E) approve, adopt or recommend any Acquisition Proposal or Alternative Acquisition Agreement, or propose publicly to approve, adopt or recommend, any Acquisition Proposal or Alternative Acquisition Agreement or (F) publicly announce that an Acquisition Proposal constitutes a Superior Proposal (any action described in this clause (i) being referred to as a “Change in Recommendation”) or (ii) allow HNR or any of its Subsidiaries to execute or enter into any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, alliance agreement, partnership agreement or other agreement or arrangement (other

- 46 -

than an Acceptable Confidentiality Agreement) with any Third Party constituting or relating to, or that is intended to or would reasonably be expected to lead to, any Acquisition Proposal, or requiring, or reasonably expected to cause, HNR to abandon, terminate, delay or fail to consummate, or that would otherwise impede, interfere with or be inconsistent with, the transactions contemplated by this Agreement, or requiring, or reasonably expected to cause, HNR to fail to comply with this Agreement (an “Alternative Acquisition Agreement”). Notwithstanding anything to the contrary contained in this Agreement, at any time prior to the receipt of the Requisite Stockholder Approval, in the event a material development or material change in circumstances (other than an Acquisition Proposal) occurs or arises after the date of this Agreement that was not known and not reasonably foreseeable by the HNR Board or the HNR Board Special Committee as of the date of this Agreement, the HNR Board Special Committee and the HNR Board may make a Change in Recommendation under clause (i)(A) or (C) above if the failure to take such action would be inconsistent with the directors’ fiduciary duties to the stockholders of HNR under applicable Law; provided, that (y) HNR has provided Buyer four (4) Business Days’ prior written notice advising Buyer that it intends to take such action and specifying, in reasonable detail, the reasons for such action (the “6.5(c) Notice”) and (z) prior to effecting any such Change in Recommendation, HNR shall, and shall direct its financial and legal advisors to, during such four (4) Business Day period, negotiate with Buyer in good faith (to the extent Buyer desires to negotiate in good faith) to make such adjustments in the terms and conditions of this Agreement which would allow the HNR Board Special Committee and/or the HNR Board not to make such Change in Recommendation consistent with its fiduciary duties.

(d) At any time prior to the Closing Date, in response to an unsolicited written Acquisition Proposal made after the date of this Agreement that (i) the HNR Board Special Committee determines in good faith (after consultation with its outside legal counsel and financial advisor) constitutes a Superior Proposal and (ii) the failure to approve or recommend such Superior Proposal would be inconsistent with the HNR Board Special Committee’s and the HNR Board’s fiduciary duties to the stockholders of HNR under applicable Law, Seller may terminate this Agreement pursuant to Section 8.1(c)(ii) and this Section 6.5(d); provided, however, that Seller shall not terminate this Agreement pursuant to Section 8.1(c)(ii) and this Section 6.5(d) unless (w) HNR has complied with its obligations under this Section 6.5, including its obligations set forth in Section 6.5(e), (x) Seller pays, or causes to be paid, to Buyer the Seller Termination Fee, the 15% Note Amount and the Additional Draw Note Amount pursuant to Section 8.3(a)(ii), (y) Seller and HNR agree to waive all rights (including rights to payment) under the Letter of Credit or any Replacement Letter of Credit pursuant to Section 8.3(b)(iii), and return the original, if any, of such Letter of Credit or Replacement Letter of Credit to Buyer or the issuer thereof, prior to or concurrently with, and as a condition to, such termination and (z) concurrently with such termination, HNR or Seller enters into an Alternative Acquisition Agreement that documents the terms and conditions of such Superior Proposal.

(e) Notwithstanding anything to the contrary contained in this Agreement, Seller shall not be entitled to terminate this Agreement pursuant to Section 8.1(c)(ii) and Section 6.5(d), (x) unless HNR shall have provided to Buyer four (4) Business Days’ prior written notice (the “6.5(e) Notice”) advising Buyer that HNR intends to take such action (and specifying, in reasonable detail, the reasons for such action and the material terms and conditions of any such Superior Proposal) and a copy of the relevant proposed transaction agreement, and (y):

(i) during such four (4) Business Day period, if requested by Buyer, the HNR Board Special Committee shall, and shall have directed its outside legal counsel and financial advisors to, have engaged in good faith negotiations with Buyer regarding changes to the terms of this Agreement intended to cause such Acquisition Proposal to no longer constitute a Superior Proposal; and

(ii) the HNR Board Special Committee shall have considered any adjustments to this Agreement (including a change to the price terms hereof) and any other agreements that may be proposed in writing by Buyer (the “Proposed Changed Terms”) no later than 5:00 p.m., New York City time, on the fourth (4th) Business Day of such four (4) Business Day period and the HNR Board Special Committee shall have determined in good faith (after consultation with its outside legal counsel and financial advisors) that the Superior Proposal would continue to constitute a Superior Proposal if such Proposed Changed Terms were to be given effect.

- 47 -

If (A) Buyer, within four (4) Business Days following its receipt of a 6.5(e) Notice makes an offer that, as determined in good faith by the HNR Board Special Committee (after consultation with its outside legal counsel and financial advisors) results in the applicable Acquisition Proposal no longer being a Superior Proposal, then HNR shall have no right to terminate this Agreement pursuant to Section 8.1(c)(ii) and Section 6.5(d) as a result of such Acquisition Proposal, and (B) any (1) material revisions to the terms of a Superior Proposal or (2) material revisions to an Acquisition Proposal that the HNR Board Special Committee had determined no longer constitutes a Superior Proposal, shall constitute a new Acquisition Proposal and shall in each case require HNR to deliver to Buyer a new 6.5(e) Notice and a new three (3) Business Day period shall commence thereafter.

(f) HNR shall promptly (and in any event within 24 hours) advise Buyer orally and in writing in the event that HNR receives any Acquisition Proposal or any inquiry, proposal or request for information, or engages in any discussions or negotiations that may reasonably be expected to lead to an Acquisition Proposal, and in connection with such notice, provide to Buyer the material terms and conditions (including the identity of the Third Party making any such Acquisition Proposal) of any such Acquisition Proposal. HNR shall (i) keep Buyer reasonably informed of the status and material details (including any material change to the terms thereof) of any such Acquisition Proposal (including any determination by the HNR Board Special Committee pursuant to Section 6.5(b)) and any discussions and negotiations concerning the material terms and conditions thereof and (ii) provide to Buyer as soon as practicable (and in any event within 24 hours) after receipt or delivery thereof copies of any written amendment or any written material with respect to such Acquisition Proposal. Without limiting the foregoing, HNR shall promptly (and in any even within 24 hours) notify Buyer orally and in writing if it determines to begin providing information or engaging in discussions or negotiations concerning an Acquisition Proposal pursuant to Section 6.5(b) and shall in no event begin providing such information or engaging in such discussions until at least 24 hours after having provided such prior written notice to Buyer. HNR shall not, and shall cause its Subsidiaries not to, in any way contract with any Person subsequent to the date of this Agreement in a manner that would restrict HNR’s ability to provide information to Buyer as required under this Agreement.

- 48 -

(g) HNR agrees that any violations of the restrictions set forth in this Section 6.5 by its Affiliates or by any of its or its Affiliates’ Representatives (acting in such capacity), including any knowing and intentional violation by a Representative (acting in such capacity) of a direction given to a Representative pursuant to the first sentence of Section 6.5(a) shall be deemed to be a breach of this Agreement (including this Section 6.5) by HNR.

(h) Nothing contained in this Agreement shall prohibit HNR, the HNR Board Special Committee or the HNR Board, directly or indirectly through their respective Representatives, from (i) taking and disclosing any position or disclosing any information reasonably required under Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or (ii) making any “stop, look and listen” communication to HNR’s stockholders pursuant to Rule 14d-9(f) promulgated under the Exchange Act; provided, that in all cases, any such action or disclosure shall comply with Section 6.5(c), Section 6.5(d), and Section 6.5(e); and provided further that any public disclosure relating or in response to an Acquisition Proposal other than (A) a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) promulgated under the Exchange Act, (B) an express rejection of any applicable Acquisition Proposal or (C) an express reaffirmation of the HNR Board Recommendations shall be deemed to be a Change in Recommendation.

(i) With respect to any HNR Proposal that does not constitute an Acquisition Proposal, (A) HNR shall not enter into, and shall cause its Subsidiaries not to enter into, any definitive agreement with respect to any such HNR Proposal until after the receipt of the Requisite Stockholder Approval (or earlier termination of this Agreement in accordance with Section 8.1), (B) HNR shall not make or permit or instruct any Affiliate or Representative to make or consent to any other Person making any public disclosure regarding such HNR Proposal until after the receipt of the Requisite Stockholder Approval (or earlier termination of this Agreement in accordance with Section 8.1); provided, that HNR may make such disclosure if and to the extent required by Law or the rules of the New York Stock Exchange so long as (x) the HNR Board has determined (based on the advice of experienced and reputable outside securities counsel) that such disclosure is required, (y) Seller has provided reasonable advance notice to Buyer of the need and rationale for such disclosure and the proposed contents thereof and (z) Seller has cooperated with Buyer in limiting the extent of such disclosure, (C) HNR shall not allow the consummation of the transactions contemplated by such HNR Proposal to be consummated prior to the Closing (or earlier termination of this Agreement in accordance with Section 8.1), (D) HNR shall cause the offeror in respect any such HNR Proposal to enter into an Acceptable Confidentiality Agreement prior to furnishing to such offeror any material nonpublic information and (E) Venezuela Approval for the transactions contemplated by such HNR Proposal may not be sought by the acquiror, HNR or any of their Affiliates or Representatives prior to the Closing (or earlier termination of this Agreement in accordance with Section 8.1).

(j) For purposes of this Agreement:

(i) “Acquisition Proposal” shall mean either an “HVDH Proposal” or an “HNR Proposal”. If an Acquisition Proposal constitutes both an HVDH Proposal and an HNR Proposal, it shall constitute an HNR Proposal and not an HVDH Proposal. An HNR Proposal that relates only to the acquisition of assets or Subsidiaries or Affiliates of HNR or Seller other than the Acquired Companies and their assets shall not constitute

- 49 -

an Acquisition Proposal. “HVDH Proposal” shall mean, any bona fide proposal or offer (other than a proposal or offer by Buyer or any of its Subsidiaries) from a Third Party relating to (i) a merger, reorganization, sale of assets, share exchange, consolidation, business combination, recapitalization, dissolution, liquidation, joint venture or similar transaction that, if consummated, would result in any Person other than HNR or Buyer owning, directly or indirectly, any of the Equity Interests of any of the Acquired Companies; (ii) the acquisition in any manner, directly or indirectly, by any Person of beneficial ownership of any of the Equity Interests of any of the Acquired Companies; (iii) any purchase, acquisition, tender offer or exchange offer that, if consummated, would result in any Person beneficially owning any of the Equity Interests of any of the Acquired Companies, (iv) other than the disposition of assets of the HVDH Companies in accordance with Section 6.1(d)(viii), the acquisition (whether by merger, consolidation, equity investment, joint venture or otherwise) by any Person of any of the assets of any of the Acquired Companies; or (v) any combination of the foregoing. “HNR Proposal” shall mean any bona fide proposal or offer (other than a proposal or offer by Buyer or any of its Subsidiaries) from a Third Party relating to (i) a merger, reorganization, sale of assets, share exchange, consolidation, business combination, recapitalization, dissolution, liquidation, joint venture or similar transaction that, if consummated, would result in any person other than HNR or Buyer owning, directly or indirectly, twenty percent (20%) or more of the Equity Interests or assets of either HNR or Seller; (ii) the acquisition in any manner, directly or indirectly, by any Person of beneficial ownership of twenty percent (20%) or more of the issued and outstanding shares of HNR Common Stock or twenty percent (20%) or more of the issued and outstanding shares of Seller or twenty percent (20%) or more of the assets of HNR or its Subsidiaries; (iii) any purchase, acquisition, tender offer or exchange offer that, if consummated, would result in any Person beneficially owning twenty percent (20%) or more of the issued and outstanding shares of HNR Common Stock or, directly or indirectly, twenty percent (20%) or more of the issued and outstanding shares of Seller; or (iv) any combination of the foregoing.

(ii) “Superior Proposal” shall mean an Acquisition Proposal that if consummated would result in the Third Party making such Acquisition Proposal owning, directly or indirectly (x) one hundred percent (100%) of the Equity Interests in HNR or Seller or one hundred percent (100%) or more of the assets of HNR or Seller (in each case assuming that such Acquisition Proposal is conditioned upon the termination of this Agreement), (y) 51% of the Equity Interests of HVDH or 100% of the assets of HVDH, or (z) 100% of all of the assets of all the Subsidiaries of HVDH, made by a Third Party as to which the HNR Board Special Committee determines in good faith, after consultation with its outside legal counsel and financial advisors, and considering such factors as the HNR Board Special Committee considers in good faith to be appropriate (including the tax consequences), (A) is on terms that are more favorable to all holders of HNR Common Stock than the transactions contemplated by this Agreement (after giving effect to all Proposed Changed Terms) from a financial point of view, (B) is not conditioned on the receipt of financing and (C) is reasonably likely to be consummated on a timely basis.

Section 6.6 Notification of Certain Matters. From and after the date hereof until consummation of the Closing, Seller shall give prompt notice to Buyer, and Buyer shall give prompt notice to Seller, upon receiving Knowledge of (a) any notice, complaint, investigation or hearing

- 50 -

Promptly following distribution to or receipt from any regulatory and/or law enforcement agency, civil plaintiff or HNR Stockholder, as applicable, Seller shall provide Buyer with all documents related to any communication or request for information, including any pleadings, court documents or correspondence, to or from any regulatory and/or law enforcement agency, civil plaintiff or HNR Stockholder regarding a violation or potential violation of any Law by HNR or any of its Subsidiaries or, to the extent accessible by HNR or Seller, by Petrodelta or any of its Subsidiaries, or any of their respective directors, officers, employees, or, to Seller’s Knowledge, Representatives.

Section 6.7 Public Announcements. The initial press release(s) announcing the execution of this Agreement shall be in a form mutually agreed upon by Buyer and Seller.

Each of Seller and HNR shall use its reasonable best efforts to defend and promptly resolve any stockholder litigation against HNR and/or its directors relating to the transactions contemplated by this Agreement that could reasonably be expected to delay or impede the consummation of the transactions contemplated by this Agreement. Prior to the Closing Date, each of HNR and Seller shall give Buyer reasonable opportunity to participate, at Buyer’s expense, in the defense or settlement of any stockholder litigation against HNR and/or its directors relating to the transactions contemplated by this Agreement, and no such settlement shall be agreed to without the prior written consent of Buyer, which shall not be unreasonably withheld, conditioned or delayed.

Section 6.10 Confidentiality.

(a) From and after the Closing, Buyer shall, and shall cause its Affiliates and Representatives to, maintain in confidence any written, oral or other information relating to HNR or any of its Subsidiaries, except that the foregoing requirements of this Section 6.10(a) shall not apply to the extent that any such information (including any report, statement, testimony or other submission to a Governmental Authority) is required by applicable Law to be disclosed, provided, that Buyer has given to HNR, to the extent permitted by applicable Law, prompt written notice of such request or requirement so that HNR or its Affiliates may at their own cost seek an appropriate order or other remedy protecting the confidential material from disclosure, and Buyer reasonably cooperates (at the cost of the disclosing party) with HNR or such Affiliate to obtain such protective order or other remedy, and in any case, Buyer shall furnish only that portion of the confidential information which, in the opinion of its counsel, Buyer is legally required to disclose; and, provided, further, that Buyer provides HNR with written notice of the information to be disclosed as far in advance of its disclosure as reasonably practicable and uses reasonable best efforts (at the cost of the disclosing party) to seek confidential treatment of such information.

(b) This Section 6.11 shall inure exclusively to the benefit of, and be binding solely upon, the parties to this Agreement and their respective successors, permitted assigns, executors and legal representatives. Nothing in this Section 6.11, expressed or implied, shall be construed to create any third-party beneficiary rights in any present or former employee, service provider, or any such Person’s alternative payees, dependents or beneficiaries, whether in respect of continued employment or resumed employment, compensation, benefits, terms of employment, or otherwise. No provision in this Agreement shall modify or amend any HVDH Company Benefit Plan unless this Agreement explicitly states that the provision “amends” such HVDH Company Benefit Plan. This shall not prevent the parties entitled to enforce this Agreement from enforcing any provision of this Agreement, but no other party shall be entitled to enforce any provision in this Agreement on the grounds that it is an amendment to such HVDH Company Benefit Plan.

Section 6.12 Post-Closing Access. Following the Closing, Seller shall, as may be reasonably required by Buyer, make available to Buyer and its Affiliates and Representatives such records of the Retained Companies related to the Acquired Companies (and their predecessors) held immediately prior to the Closing for so long as and to the extent required by applicable Law (but in no event less than seven years after the Closing Date). In addition, following the Closing, Seller shall make available to Buyer the employees and Representatives of the Seller and its Affiliates whose assistance, expertise, testimony, notes, recollections or presence (including participation as a witness in a deposition, hearing or trial) is necessary or appropriate to assist Buyer (i) in the defense or prosecution of any Legal Proceeding relating to the Acquired Companies, (ii) in the preparation of any Tax returns or filings or financial or accounting statements in respect of any of the Acquired Companies or Buyer or any of its other Affiliates and (iii) in the transition of the business, operations and employees of the HVDH Companies from Seller to Buyer.

If Seller fails to pay the Seller Termination Fee pursuant to this Section 8.3 when due, and, in order to obtain such payment, Buyer commences a suit that results in a judgment against such party for the Seller Termination Fee, Seller shall pay or cause to be paid to Buyer its costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the Seller Termination Fee from the date such payment was required to be made until the date of payment at an interest rate of eleven percent (11%) per annum.

Except as expressly set forth herein (including Section 8.2 and Section 8.3), all fees and expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement shall be paid by the party incurring such fees or expenses, whether or not the transactions contemplated by this Agreement are consummated.

(b) Buyer’s share of any Taxes of the HVDH Companies shall be 51% of the amount of all Taxes incurred by an HVDH Company (or for which an HVDH Company is liable), but exclusive of Taxes described under Section 9.2(a)(i), (iii), (iv) or (v) which will be for the account of Seller, with respect to any taxable period that begins after the Effective Date or any portion of a Section 9.2 Period attributable under Section 9.2(d) to the period that begins after the Effective Date.

(c) Notwithstanding the foregoing, Buyer shall be attributed an amount of Taxes incurred by an HVDH Company (or for which an HVDH Company is liable) with respect to any distributions on the Subject Shares that are transferred by the Seller to the Buyer under Section 2.1(a) without regard to Section 9.2(d).

(i) In the case of ad valorem, property, or franchise or similar Taxes imposed on any HVDH Company based on capital or number of shares of stock authorized,

issued or outstanding, the portion attributable to the portion of such period that ends on the Effective Date shall be the amount of such Taxes for the entire Section 9.2 Period multiplied by a fraction, the numerator of which is the number of days in such Section 9.2 Period until and including the Effective Date and the denominator of which is the number of days in the entire Section 9.2 Period;

(ii) In the case of all other Taxes, the portion attributable to the period that ends on or before the Effective Date shall be determined on the basis of an interim closing of the books of the applicable HVDH Company as of the Effective Date; provided, that any items of income, gain, loss, deduction, exemption, or allowances that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the portion of the Section 9.2 Period ending on and including the Effective Date and the portion of the Section 9.2 Period beginning after the Effective Date in proportion to the number of days in each such period relative to the entire Section 9.2 Period.

(e) Any refund or credit of Taxes, or any tax benefit or reduction (including as a result of any overpayment of Taxes) that is received in cash or that reduces the amount of HVDH Company Taxes paid after the Effective Date (a “Tax Credit”) shall be attributable to a taxable period pursuant to this Section 9.2 in the same manner as the Tax to which such Tax Credit relates. With regard to the VAT Fiscal Unity, a Tax Credit shall also include a reclaim of VAT to which any HVDH Company as part of a VAT Fiscal Unity is entitled to, determined (for allocation purposes only) as if the relevant HVDH Company was not part of the VAT Fiscal Unity.

Section 9.3 Payment of Taxes, Refunds and Credits.

(a) With respect to any Taxes due (taking into account all extensions properly obtained) prior to the Closing Date, each of Buyer and Seller shall use its reasonable best efforts to cause the HVDH Companies to pay their Taxes when due (taking into account all extensions properly obtained). Notwithstanding the foregoing, Seller shall pay any VAT payable by any VAT Fiscal Unity to the relevant Taxing Authority. If the HVDH Companies do not pay their Taxes when as provided in this Section 9.3(a), either party hereto may, after fifteen (15) days’ notice to the other party hereto, pay such Taxes.

(b) Taxes shall be borne by Buyer and Seller according to the allocation of liability in Section 9.2. In furtherance of the foregoing, to the extent that either Buyer or Seller has borne more than its proportionate share of such Taxes, either indirectly (through its ownership of HVDH shares, to the extent an HVDH Company has funded such Taxes out of its own assets) or directly (pursuant to Section 9.3(a) or otherwise) (such party, the “Excess Tax Party”) the other party hereto shall reimburse the Excess Tax Party in accordance with Section 9.8 for any Taxes properly allocable to such other party under Section 9.2, in the currency in which such Tax is owed, such that each of Buyer and Seller have economically borne the appropriate amount of Tax.

(c) If a Tax Credit of an HVDH Company is available with respect to a Tax period (or portion thereof) beginning prior to the Closing Date, Buyer and Seller shall appropriately

- 65 -

receive the benefits of such Tax Credit to the extent allocated to each of them pursuant to Section 9.2. In furtherance of the foregoing, to the extent that either Buyer or Seller has received more than its proportionate share of such Tax Credit, either indirectly (through its ownership of HVDH shares, to the extent an HVDH Company has received such Tax Credit) or directly (to the extent the Tax Credit has reduced amounts that such party otherwise would have paid directly pursuant to Section 9.3(a) or otherwise), such party shall reimburse the Excess Tax Party, or the Buyer and Seller together shall cause HVDH to reimburse the Excess Tax Party for any Tax Credit actually received that is properly allocable to the Excess Tax Party under Section 9.2, in the currency in which such Tax Credit is received (provided, that, for this purpose, a Tax credit, benefit or reduction in Tax shall be deemed to be actually received when applied to reduce cash Taxes otherwise payable).

(d) Notwithstanding any provision to the contrary in Section 9.3(c), if a VAT Fiscal Unity exists during a taxable period or portion thereof, Seller shall pay to the HVDH Company an amount equal to the amount of any VAT receivable attributable to such period or portion thereof, which shall be determined (for allocation purposes only) as if the relevant HVDH Company was not part of the VAT Fiscal Unity.

Section 9.4 Amendment of Tax Returns. Prior to the Liquidation Date, neither the Buyer nor any of its Affiliates shall amend, refile, revoke or otherwise modify any Tax Return or Tax election of any HVDH Company with respect to any Tax Return described in Section 9.1 without the prior written consent of the Seller, which consent shall not be unreasonably conditioned, withheld or delayed.

Section 9.5 Tax Periods. To the extent permissible but not required pursuant to applicable Law, the parties shall cooperate to cause the HVDH Companies to take all steps as are or may be reasonably necessary (including the filing of elections or returns with applicable Taxing Authorities) to cause such period to end on the Closing Date, or as soon thereafter as is reasonably practicable.

Section 9.6 VAT Fiscal Unity. Immediately after the Closing Date, Seller shall simultaneously send a copy to Buyer and file a letter with the relevant Taxing Authority informing such Taxing Authority that the relevant HVDH Company no longer forms part of the VAT Fiscal Unity as of the Closing Date. Seller will, within ten (10) days after receipt, inform Buyer of any correspondence of the relevant Taxing Authority regarding the separation of any of the HVDH Companies from such VAT Fiscal Unity.

Section 9.7 Cooperation; Audits; Tax-Related Actions.

(a) In connection with the preparation of Tax Returns (including amended Tax Returns), audit examinations, Tax refund claims, applications for relief or ruling and any actions relating to the Tax liabilities imposed on any HVDH Company (or any successor thereof) or otherwise discussed in this Article IX, Buyer, on the one hand, and the Seller, on the other hand, shall cooperate fully with each other, including the furnishing or making available during normal business hours of records, personnel (as reasonably required and to the extent not unduly burdensome), books of account, powers of attorney or other materials necessary or helpful for the preparation of such Tax Returns, the conduct of audit examinations or the defense of actions

- 66 -

by Taxing Authorities as to the imposition of Taxes. Seller (until the Closing Date), and Buyer (after the Closing Date), shall and to the extent practicable shall cause the HVDH Companies to (i) retain all books and records with respect to Tax matters pertinent to any HVDH Company relating to any taxable period beginning before the Closing Date until the earlier of the expiration of the applicable statute of limitations (including any extension thereof) for the respective taxable periods or the Liquidation Date, and to abide by all record retention agreements entered into with any Taxing Authority, and (ii) give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and allow such other party to take possession of such books and records at such party’s own expense.

(b) Buyer and the Seller shall, upon request, use commercially reasonable efforts to obtain any certificate or other document from any Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).

Section 9.8 Tax Claims.

(a) Any Claim for payment, reimbursement or contribution pursuant to Section 9.3 (a “Tax Claim”) shall be made pursuant to this Section 9.8. In order to assert a Claim for payment pursuant to Section 9.3, a party hereto (the “Tax Payee”) shall give prompt written notice to the party required to make payment to such Tax Payee (the “Tax Payor”). Such Tax Claim shall be made reasonably promptly after the Tax Payee determines that it intends to seek payment pursuant to Section 9.3, provided, however, that no failure to give such prompt written notice shall relieve Tax Payor of any of its obligations hereunder except to the extent that Tax Payor is materially and adversely prejudiced by such failure.

(b) Any payment pursuant to this Article IX in respect of any Tax Claim shall be (i) made net of any withholding Tax required by Law and (ii) effected by wire transfer of immediately available funds from Tax Payor or one of its Affiliates to an account designated by the applicable Tax Payee within three (3) Business Days after the determination thereof.

(c) All Tax Claims pursuant to Section 9.8 shall survive until the later of (A) six (6) months after the Closing Date and (B) the earlier of (1) the Liquidation Date and (2) the date that is ninety (90) days after the expiration of the applicable statute of limitations (at which point they will terminate) to the fullest extent permitted by law; provided, that written notice of a Tax Claim shall extend the applicable survival period for such Tax Claim until such Tax Claim is conclusively resolved.

(d) If, after negotiating in good faith, Seller and Buyer are unable to reach an agreement relating to a Tax Claim or the payment of any Tax Claim, such dispute shall be submitted to the Referee pursuant to Section 9.11.

Section 9.9 Transfer Taxes. Notwithstanding any other provision of this Article IX, all Transfer Taxes imposed by any Taxing Authority in connection with the transactions contemplated by this Agreement shall be borne by the Party with legal liability for such Transfer Tax.

Section 9.10 Tax Sharing Agreements. All Tax sharing agreements or similar agreements with respect to or involving Seller and its Affiliates on the one hand, and the Acquired Companies on the other hand, shall be terminated as of the Closing Date and, after the Closing Date, the Acquired Companies shall not be bound thereby or have any liability thereunder.

- 67 -

Section 9.11 Referee. If, after negotiating in good faith, Seller and Buyer are unable to reach an agreement relating to any Tax matter under this Article IX, the dispute shall be submitted to a mutually acceptable independent accounting firm of national repute (the “Referee”) jointly selected by Seller and Buyer within five (5) Business Days of the date on which a party makes the request to refer such dispute to an expert. Seller and Buyer shall instruct the Referee to resolve any disputed items within fifteen (15) Business Days of having such items referred to it, pursuant to such procedures as it may require. The parties shall cooperate with the Referee, provide it promptly with all information that it reasonably requires and shall promptly act to implement the decision of the Referee. The costs, fees and expenses of the Referee shall be allocated 50% to Buyer and 50% to Seller.

Section 10.3 Interpretation; Certain Definitions. The parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by

- 69 -

the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement. When a reference is made in this Agreement to an Article, Section, Appendix, Schedule, Annex or Exhibit, such reference shall be to an Article or Section of, or an Appendix, Schedule, Annex or Exhibit to, this Agreement, unless otherwise indicated. The table of contents and headings for this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein,” “hereby,” “hereto” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole, including all Exhibits, Schedules and Annexes and Appendices, and not to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined herein. References to a Person are also to its successors and permitted assigns. The specification of any dollar amount in any representation or warranty contained in Article IV or Article V is not intended to imply that such amount, or higher or lower amounts, are or are not material for purposes of this Agreement, and no party shall use the fact of the setting forth of any such amount in any dispute or controversy between or among the parties as to whether any obligation, item or matter not described herein or included in the Seller Disclosure Schedule or the Buyer Disclosure Schedule is or is not material for purposes of this Agreement. Words describing the singular number shall be deemed to include the plural and vice versa, and words denoting any gender shall be deemed to include all genders.

Section 10.4 Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, illegal or incapable of being enforced under any present or future Law or public policy, (a) such term or other provision shall be fully separable, (b) this Agreement shall be construed and enforced as if such invalid, illegal or unenforceable provision had never comprised a part hereof, and (c) all other conditions and provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable term or other provision or by its severance herefrom so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable Law in a mutually acceptable manner in order that the transactions contemplated hereby are fulfilled as originally contemplated to the fullest extent possible.

Section 10.5 Assignment. Neither this Agreement nor any rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties hereto, except that Buyer may assign its rights and delegate its obligations hereunder to one or more of its Affiliates, as long as Buyer remains ultimately liable for all of Buyer’s obligations hereunder. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective permitted successors and permitted assigns.

- 70 -

Section 10.6 Entire Agreement.

Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance with Section 8.5 without notice or liability to any other Person. The representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the Knowledge of any of the parties hereto. Accordingly, Persons other than the parties hereto may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Section 10.8 Governing Law. This Agreement and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this Agreement shall be governed by, and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of laws provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware; provided, that (i) the Deed of Transfer, (ii) all other notarial deeds executed by the Notary, and (iii) all shareholders’ resolutions / minutes of duly convened shareholders’ meetings in relation to such notarial deeds shall be exclusively governed by, and construed in accordance with the laws of The Netherlands without giving effect to any choice or conflict of laws provision or rule (whether of The Netherlands or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than The Netherlands.

Accordingly, except as otherwise set forth in this Section 10.9, (i) unless this Agreement has been terminated pursuant to Article XIII, the parties acknowledge and agree that the parties hereto shall be entitled, without posting a bond, security or other indemnity, to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity, and (ii) if this Agreement has been terminated pursuant to Article XIII, the parties acknowledge and agree that Seller shall be entitled, without posting a bond, security or other indemnity, to an injunction, specific performance and other equitable relief to prevent breaches of the Surviving Provisions and to enforce specifically the terms and provisions of such Surviving Provisions.

To the fullest extent permitted by applicable Law, HNR waives presentment to, demand of payment from and protest to any other Person of any of the HNR Guaranteed Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment. The obligations of HNR hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the HNR Guaranteed Obligations, or otherwise. Notwithstanding any of the foregoing, nothing herein shall be deemed to waive or limit HNR’s ability to assert any claims, defenses or other rights that the Seller or its Affiliate may have under this Agreement.

(“PDVSA”) or the Bolivarian Republic of Venezuela (including

- 73 -

any Governmental Authority thereof) and all Persons who have been or are directors, officers, agents or employees of PDVSA (in each case, in their respective capacities as such) from any and all debts, guarantees, liabilities, costs, expenses, interest and obligations whatsoever, whether accrued or fixed, absolute or contingent, matured or unmatured, reserved or unreserved, or determined or determinable, including those arising under any Law, claim (including any third Person claim), demand, action, whether asserted or unasserted, or order, writ, judgment, injunction, decree, stipulation, determination or award entered by or with any Governmental Authority, or any fines, damages or equitable relief that is imposed, in each case, including all costs and expenses relating thereto, whether at law or in equity, whether arising under any Contract, release or warranty, by operation of Law or otherwise, whether known or unknown, to the extent existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed prior to the Closing Date in respect of the assets, operations or business of HNR and its Subsidiaries, including Seller.

b. If an Event of Default (other than an Event of Default specified in Sections 6(a)(iv) or (v)) occurs and is continuing, Holder may declare, by sending written notice to the Company, the principal of and accrued and unpaid interest, if any, on this Note to be due and payable. Upon sending such a notice of acceleration, such principal and accrued and unpaid interest shall be due and payable immediately. In the event of the acceleration of this Note because an Event of Default described in Section 6(a)(iii) has occurred and is continuing, the acceleration of the Indebtedness evidenced by this Note shall be automatically annulled if the Event of Default or payment default triggering such Event of Default pursuant to Section 6(a)(iii) shall be remedied or cured by the Company, a Subsidiary of the Company or the Guarantor or waived by Holder within 20 days after the declaration of acceleration with respect thereto and if (1) the annulment of the acceleration of this Note would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all existing Events of Default, except nonpayment of principal or interest on this Note that became due solely because of the acceleration of this Note, have been cured or waived in writing.

No such rescission shall affect any subsequent default or impair any right consequent thereto.

In furtherance thereof, the Company and Holder, by acceptance of this Note, stipulate and agree that none of the terms and provisions contained in the Purchase Agreement or this Convertible Note shall ever be construed to create a contract to pay for the use, forbearance or detention of money with interest at a rate or in an amount in excess of the Maximum Rate, or to pay an amount of interest in excess of that permitted to be charged under Applicable Law.

ARTICLE II

GUARANTY

SECTION 2.1 Guaranty. The Guarantor hereby absolutely, irrevocably and unconditionally guarantees as a primary obligor and not merely as a surety, to the Guaranteed Parties, the prompt payment and performance of all obligations, including all principal, interest and reimbursement obligations, arising under the Note (the “Guaranteed Obligations”), whether primary or secondary (whether by way of endorsement or otherwise), whether now existing or hereafter arising, whether or not from time to time reduced or extinguished (except by payment thereof) or hereafter increased or incurred, whether enforceable or unenforceable, whether or not discharged (other than by payment), stayed or otherwise affected by any Debtor Relief Law or proceeding thereunder, whether created directly with a Guaranteed Party or acquired by such Guaranteed Party through assignment or endorsement or otherwise, whether matured or unmatured, whether joint or several, as and when the same becomes due and payable (whether at maturity or earlier, by reason of acceleration, mandatory repayment or otherwise), in accordance with the terms of the Note and all renewals, extensions or modifications thereof.

SECTION 2.2 Bankruptcy Limitations on Guarantor. Notwithstanding anything to the contrary contained in Section 2.1, it is the intention of the Guarantor and the Seller that, in any proceeding involving the bankruptcy, adjustment of debts, relief of debtors or insolvency or any similar proceeding with respect to the Guarantor or his assets, the amount of the Guarantor’s obligations with respect to the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) shall be equal to, but not in excess of, the maximum amount thereof not subject to avoidance or recovery by operation of Debtor Relief Laws. To that end, but only in the event and to the extent that the Guarantor’s obligations with respect to the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) or any payment made pursuant to such Guaranteed Obligations (or any other obligations of the Guarantor to the

Guaranteed Parties) would, but for the operation of the first sentence of this Section 2.2, be subject to avoidance or recovery in any such proceeding under Debtor Relief Laws, the amount of the Guarantor’s obligations with respect to the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) shall be limited to the largest amount which, after giving effect thereto, would not, under Debtor Relief Laws, render the Guarantor’s obligations with respect to the Guaranteed Obligations (or any other obligations of the Guarantor to the Guaranteed Parties) unenforceable or avoidable or otherwise subject to recovery under Debtor Relief Laws. To the extent any payment actually made pursuant to the Guaranteed Obligations exceeds the limitation of the first sentence of this Section 2.2 and is otherwise subject to avoidance and recovery in any such proceeding under Debtor Relief Laws, the amount subject to avoidance shall in all events be limited to the amount by which such actual payment exceeds such limitation and the Guaranteed Obligations as limited by the first sentence of this Section 2.2 shall in all events remain in full force and effect and be fully enforceable against the Guarantor until payment in full of the Guaranteed Obligations. The first sentence of this Section 2.2 is intended solely to preserve the rights of the Guaranteed Parties hereunder against the Guarantor in such proceeding to the maximum extent permitted by Debtor Relief Laws and neither the Guarantor nor any other Person shall have any right or claim under such sentence that would not otherwise be available under Debtor Relief Laws in such proceeding.

SECTION 2.3 No Subrogation. Notwithstanding any payment or payments by the Guarantor hereunder, or any setoff or application of funds of the Guarantor by any Guaranteed Party, or the receipt of any amounts by any Guaranteed Party with respect to any of the Guaranteed Obligations, the Guarantor shall not be entitled to be subrogated to any of the rights of any Guaranteed Party or against any collateral security held by any Guaranteed Party for the payment of the Guaranteed Obligations, until all amounts owing to the Guaranteed Parties on account of the Guaranteed Obligations are paid in full in cash. If any amount shall be paid to the Guarantor on account of such subrogation, reimbursement or contribution rights at any time when all of such Guaranteed Obligations shall not have been paid in full, such amount shall be held by the Guarantor in trust for the Guaranteed Parties, segregated from other funds of the Guarantor, and shall, forthwith be turned over to the Guaranteed Parties in the exact form received by the Guarantor (duly endorsed by the Guarantor to the applicable Guaranteed Party, if required) to be applied against the Guaranteed Obligations, whether matured or unmatured.

SECTION 2.4 Nature of Guaranty.

(a) The Guarantor agrees that this Guaranty is a continuing, unconditional guaranty of payment and performance and not of collection, and that his obligations under this Guaranty shall be primary, absolute and unconditional, irrespective of, and unaffected by:

(i) the genuineness, legality, validity, regularity, enforceability or any future amendment or modification of, or change in, or supplement to, the Purchase Agreement, any other Document or any other agreement, document or instrument to which the Guarantor or any Affiliated Entity is or may become a party;

(ii) any action under or in respect of the Purchase Agreement or any other Document, any exercise of any remedy, power or privilege contained therein or available to any party thereto at law, in equity or otherwise, or waiver or refraining from exercising

any such remedies, power or privileges (including any manner of application of any sums by whomever paid or however realized to any Guaranteed Obligations owing by the Company, the Guarantor, any other guarantor or any other Person to any Guaranteed Party in such manner as any Guaranteed Party shall determine in its reasonable discretion);

(iii) the absence of any action to enforce this Guaranty, the Purchase Agreement or any other Document or the waiver or consent by any Guaranteed Party or any other Person with respect to any of the provisions of the Purchase Agreement or any other Document;

(iv) the existence, value or condition of, or failure of any Guaranteed Party to perfect its lien against, any security for or other guaranty of the Guaranteed Obligations or any action, or the absence of any action, by any Guaranteed Party or any other secured party in respect of such security or guaranty (including, without limitation, the release of any such security or guaranty);

(v) any structural change in, restructuring of or other similar organization change of any Affiliated Entity; or

(vi) any other action or circumstances which might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor (other than payment of the Guaranteed Obligations);

it being agreed by the Guarantor that, subject to the first sentence of Section 2.2, his obligations under this Guaranty shall not be discharged until the final payment and performance, in full, of the Guaranteed Obligations.

(b) The Guarantor agrees that the Guaranteed Obligations and his obligations under this Guaranty are not and shall not be subject to any counterclaims, offsets or defenses of any kind (other than the defense of payment) against any Guaranteed Party whether now existing or which may arise in the future.

(c) The Guarantor hereby agrees and acknowledges that the Guaranteed Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this Guaranty.

SECTION 2.5 Waivers. To the extent permitted by Applicable Law, the Guarantor expressly waives all of the following rights and defenses (and agrees not to take advantage of or assert any such right or defense):

(a) any rights he may now or in the future have under any statute, or at law or in equity, or otherwise, to compel any Guaranteed Party or any other secured party to proceed in respect of the Guaranteed Obligations against the Company or any other Person or against any security for or other guaranty of the payment and performance of the Guaranteed Obligations before proceeding against, or as a condition to proceeding against, the Guarantor;

(b) any defense based upon the failure of any Guaranteed Party or any other secured party to commence an action in respect of the Guaranteed Obligations against any other guarantor or any other Person or any security for the payment and performance of the Guaranteed Obligations;

SECTION 4.2 Amendments, Waivers and Consents. None of the terms or provisions of this Guaranty may be waived, amended, supplemented or otherwise modified, nor any consent be given, except upon prior written agreement of the parties hereto and HNR.

SECTION 4.3 Governing Law; Jurisdiction; Venue; Service of Process.

(a) Governing Law. This Guaranty and all issues hereunder shall be governed by and construed in accordance with the laws of the State of New York (excluding choice-of-law principles of the laws of such State that would permit the application of the laws of a jurisdiction other than such State).

(b) Submission to Jurisdiction. The Guarantor agrees that any suit or proceeding arising in respect of this Guaranty or any of the other Documents will be tried in the U.S. District Court for the Southern District of New York or in any state court located in the City and County of New York, and the Guarantor agrees to submit to the jurisdiction of, and to venue in, such courts. The Guarantor consents to process being served by or on behalf of any Guaranteed Party in any suit, action or proceeding of the nature referred to in this Section 4.3(b) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to him at his address specified in Section 4.1 of this Guaranty. The Guarantor agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon him in any such suit, action or proceeding, and (ii) shall, to the fullest extent permitted by Applicable law, be taken and held to be valid personal service upon and personal delivery to him. Notices hereunder shall be conclusively presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service. Nothing in this Guaranty shall affect the right of any Guaranteed Party to serve process in any other manner permitted by Law or to commence legal proceedings or otherwise proceed against the Guarantor in any other jurisdiction.

(c) Appointment of Company as Agent for the Guarantor. The Guarantor hereby irrevocably appoints and authorizes the Company to act as his agent for service of process and notices required to be delivered under this Guaranty or under the other Documents, it being understood and agreed that receipt by the Company of any summons, notice or other similar item shall be deemed effective receipt by the Guarantor.

SECTION 4.4 Waiver of Jury Trial.

EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT OR HE MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT OR HE AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS GUARANTY AND THE OTHER DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 5.4.

SECTION 4.5 No Waiver by Course of Conduct, Cumulative Remedies. No course of dealing between the Guarantor, any Guaranteed Party or any other secured party or their respective agents or employees shall be effective to change, modify or discharge any provision of this Guaranty or any other Document or to constitute a waiver of any default or Event of Default. The enumeration of the rights and remedies of the Guaranteed Parties set forth in this Guaranty is not intended to be exhaustive and the exercise by any Guaranteed Party of any right or remedy shall not preclude the exercise of any other rights or remedies, all of which shall be cumulative, and shall be in addition to any other right or remedy given hereunder or under the

other Documents or that may now or hereafter exist at law or in equity or by suit or otherwise. Neither any Guaranteed Party nor any other secured party shall by any act, delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any Event of Default. No delay or failure to take action on the part of any Guaranteed Party or any other secured party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise of any such right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege or shall be construed to be a waiver of any Event of Default. A waiver by any Guaranteed Party or any other secured party of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which such Guaranteed Party or such secured party would otherwise have on any future occasion.

SECTION 4.6 Successors and Assigns. The provisions of this Guaranty shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns; except that the Guarantor may not assign or otherwise transfer any of his rights or obligations under this Guaranty without the prior written consent of the Guaranteed Parties and HNR.

SECTION 4.7 Severability of Provisions. Any provision of this Guaranty or any other Document which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating the remainder of such provision or the remaining provisions hereof or thereof or affecting the validity or enforceability of such provision in any other jurisdiction.

SECTION 4.8 Counterparts. This Guaranty may be executed in any number of counterparts (and by different parties hereto in separate counterparts), each of which shall constitute an original, but all of which taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page to this Guaranty or any document or instrument delivered in connection herewith by facsimile or in electronic (i.e., “pdf” or “tif”) form shall be effective as delivery of a manually executed counterpart of this Guaranty or such other document or instrument, as applicable.

SECTION 4.9 Integration. This Guaranty and the other Documents, and any separate letter agreements with respect to fees, constitute the entire contract of the parties relating to the subject matter hereof and supersede all previous agreements and understandings, written or oral, relating to the subject matter hereof.

SECTION 4.10 Acknowledgements. The Guarantor hereby acknowledges that:

(a) he has received a copy of the Purchase Agreement, the Note and the other Documents and has reviewed and understands the same;

(b) neither any Guaranteed Party nor any other secured party has any fiduciary relationship with or duty to the Guarantor arising out of or in connection with this Guaranty or any of the other Documents, and the relationship between the Guarantor, on the one hand, and the Seller and the other Guaranteed Parties, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Documents or otherwise exists by virtue of the transactions contemplated hereby or thereby among the Guarantor or any Affiliated Entity and the Guaranteed Parties.

SECTION 4.11 Release. At such time as the Guaranteed Obligations (other than contingent indemnification obligations if any) shall have been paid in full in cash, this Guaranty and all obligations (other than those expressly stated to survive such termination or as may be reinstated after such termination) of the Seller and the Guarantor hereunder shall terminate, all without delivery of any instrument or performance of any act by any party.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration (the receipt and sufficiency of which is hereby acknowledged by HNR), HNR hereby agrees, on behalf of itself and the other Retained Companies, as follows:

HNR, for itself and for each Retained Company, and its and their respective successors and assigns, as applicable (collectively, the “Releasors”), DOES HEREBY REMISE, RELEASE AND FOREVER DISCHARGE the Acquired Companies and their respective directors, officers, trustees, employees, agents, servants, successors and assigns, as applicable (collectively, the “Releasees”) of and from any and all manner of actions, causes of action, suits, complaints, debts, accounts, due accounts, bonds, covenants, contracts, claims, demands, damages, costs, fines, penalties, expenses and any and all legal obligations and compensation of whatsoever kind and howsoever arising, in law or in equity, whether known or unknown, suspected or unsuspected (collectively, the “Claims”), including without limitation any Claims whether authorized or provided for by by-law, resolution, contract or otherwise, which the Releasors or any of them have had, now have or hereafter can, will or may have against the Releasees or any of them in respect of any matter or thing arising at or before the Closing Date; provided, that, for the avoidance of doubt, nothing contained herein shall operate to release Buyer or Buyer Guarantor from any Claims arising under the Share Purchase Agreement, the Letter of Credit, the Buyer Promissory Note, the ▇▇▇▇▇▇▇▇ Guaranty, or any of the transactions contemplated thereunder.

HNR further covenants and agrees not to, and to cause each other Releasor not to, directly or indirectly, join, assist, aid or act in concert in any manner whatsoever with any other person in the making of any claim or demand or in the bringing of any proceeding or action in any manner whatsoever against the Releasees or any of them with respect to the Claims released or discharged pursuant to this Release.

3.	HNR hereby represents, warrants and covenants that the Releasors have not assigned and will not assign to any other person any of the Claims that the Releasors are releasing herein.

The facts in respect of which this Release is made may prove to be other than or different from the facts now known by any of the Releasors or Releasees or believed by any of them to be true. HNR expressly accepts and assumes the risk of the facts being different and agree that all of the terms of this Release will be in all respects effective and not subject to termination or rescission by any discovery of any difference in facts.

If any provision of this Release or any part of any provision of this Release is held under any circumstances to be invalid or unenforceable in any jurisdiction, then (i) such provision or part thereof shall, with respect to such circumstances and in such jurisdiction, be deemed amended to conform to applicable laws so as to be valid and enforceable to the fullest possible extent, (ii) the invalidity or unenforceability of such provision or part thereof under such circumstances and in such jurisdiction shall not affect the validity or enforceability of such provision or part thereof under any other circumstances or in any other jurisdiction, and (iii) such invalidity or unenforceability of such provision or part thereof shall not affect the validity or enforceability of the remainder of such provision or the validity or enforceability of any other provision of this Release. Each provision of this Release is separable from every other provision of this Release, and each provision of this Release is separable from every other part of such provision.

6.	Capitalized terms used but not defined herein shall have the meaning given to them in the Share Purchase Agreement.

This Release and all actions, proceedings or counterclaims (whether based on contract, tort or otherwise) arising out of or relating to this Release shall be governed by, and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of laws provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

The Releasors irrevocably submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware, County of New Castle, (or, if (but only if) such court shall be unavailable, any other court of the State of Delaware or any Federal court sitting in the State of Delaware), for the purpose of any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or relating to this Release and each of the Releasors irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined exclusively in the Court of Chancery of the State of Delaware, County of New Castle (or, if (but only if) such court shall be unavailable, any other court of the State of Delaware or any Federal court sitting in the State of Delaware).

the right of any party to serve legal process in any other manner permitted by Law, (b) consents to submit itself to the personal jurisdiction of the Delaware Court of Chancery, County of New Castle, any other court of the State of Delaware, County of New Castle, and any Federal court sitting in the State of Delaware for the purpose of any dispute arising out of this Release or the transactions contemplated by this Release, (c) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court and (d) agrees that it will not bring any action relating to this Release or the transactions contemplated by this Release in any court other than the Delaware Court of Chancery located in the County of New Castle (or, if (but only if) such court shall be unavailable, any other court of the State of Delaware or any Federal court sitting in the State of Delaware). Each of the Releasors agrees that a final judgment in any action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.
