What is the purpose of this document

          4.02 Notwithstanding Section 4.01, the First Option will become exercisable without regard to the occurrence of Payout for a period of sixty (60) days (or the date that Fair Market Value is determined, if later) following notice by Resolute of its intent to offer Resolute’s interest in the Aneth Assets for Sale (as defined). The terms of the option, other than the exercise thereof, shall be governed by the terms of Article 3, provided that the closing of the purchase pursuant to the exercise shall occur simultaneously with the Sale giving rise to the notice. If Resolute fails to consummate a Sale following the notice thereof, however, the exercise of the option shall be void and the rights of the parties shall be as if no such Sale notice had been given; provided, however, in such event, unless the failure to consummate the Sale is due to the breach of a third party to consummate the sale, Resolute shall reimburse NNOG for NNOG’s reasonable costs and expenses, including without limitation its attorney and consultant fees, incurred by NNOG in pursuing such option.

          4.03 NNOG shall have a right of first negotiation concerning any proposed Sale of the Aneth Assets by Resolute. Said right of first negotiation shall be in addition to the rights that already exist in NN, if any. If Resolute intends to offer its interest in the Aneth Assets for Sale, and prior to any announcement of such intent to, or negotiations or discussions with, any third party, Resolute shall accord NNOG an exclusive right of first negotiation for a period of sixty days (the “Exclusive Negotiation Period”). During such Exclusive Negotiation Period, Resolute will negotiate in good faith directly and exclusively with NNOG to arrive at a mutually agreeable Fair Market Value of such assets determined as provided in Article 3 hereof, and any other mutually agreeable terms and conditions of a sale of such Assets from Resolute to NNOG. This right of first negotiation is exclusive and personal to NNOG and may not be assigned or transferred in any way. Such right shall terminate upon a change in control of NNOG, such change of control defined substantially similarly to the definition in Article 4.01. Such negotiation shall include only the Aneth Assets, whether Resolute intends to include other assets as part of the Sale or not. This right of first negotiation is not intended to be in derogation or substitution for any preference right that NN may enjoy under Navajo law, or to preclude NNOG from obtaining the Aneth Assets in cooperation with NN exercising such preference right. Similarly, such right of first negotiation is not intended to give the NN any right, preference or concession it does not have under applicable law. At either Resolute’s or NNOG’s election, the parties will engage a mutually acceptable, nationally recognized energy evaluation firm to provide guidance on the Fair Market Value of the assets, as determined above. The parties shall share equally the cost of such firm. No contract of sale shall exist until definitive agreements fully agreeable to both parties in their sole and absolute discretion as to each and every term including price are executed.

ARTICLE V.
ASSISTANCE BETWEEN THE PARTIES

          5.01 For so long as Resolute, NNOG and their affiliates hold in the aggregate the largest amount of working interest in the Aneth Unit, and Resolute’s working interest is greater than NNOG’s, NNOG shall use its best good faith efforts to cause Resolute to be elected and remain operator of the Aneth Unit and any non-unit properties within the Aneth Assets.

          5.02 Resolute and NNOG shall enter into a mutually acceptable joint operating agreement concerning any properties not subject to a unit operating agreement. NNOG will support Resolute in attempting to amend the Aneth Unit Operating Agreement to update and improve the form in order to encourage development in any manner consistent with NNOG’s interest.

          5.03 Resolute will work with NNOG in good faith to guide and assist NNOG in expanding its oil and gas operating capability. In this regard, Resolute or its affiliates or other persons on its behalf will share technical and other information with NNOG concerning the Aneth Assets; provided (i) that Resolute will have the discretion to determine appropriate amounts and types of data to share, it being understood that such sharing should not impede efficient day-to-day operations and business nor become an unreasonable burden on NNOG, and (ii) that NNOG has the legal right to share such data. NNOG ACKNOWLEDGES THAT RESOLUTE MAY NOT SHARE ALL INFORMATION IT MAY HAVE. NNOG ACKNOWLEDGES THAT ANY SUCH INFORMATION PROVIDED TO NNOG, INCLUDING, WITHOUT LIMITATION, ANY ASSESSMENTS, ESTIMATES, ANALYSIS, STUDIES, PLANS, MODELS, FORECASTS AND SIMILAR INFORMATION ARE PROVIDED WITHOUT REPRESENTATION OR WARRANTY OF ANY KIND. RESOLUTE SHALL HAVE NO LIABILITY OR OBLIGATION TO NNOG CONCERNING THE QUALITY OF SUCH INFORMATION REGARDLESS OF THE NATURE OF ANY INACCURACY, ERROR, INCOMPLETENESS OR OTHER PROBLEM WITH THE INFORMATION. NNOG AGREES THAT RESOLUTE SHALL HAVE NO OBLIGATION TO KEEP ANY SUCH INFORMATION CURRENT OR TO CORRECT OR ADJUST SUCH INFORMATION IF RESOLUTE SHOULD LEARN OF ANY INACCURACY, ERROR INCOMPLETENESS OR OTHER PROBLEM WITH THE INFORMATION. RELIANCE BY NNOG ON ANY INFORMATION PROVIDED BY OR ON BEHALF OF RESOLUTE OR ANY OF ITS AFFILIATES, AGENTS, REPRESENTATIVES, ADVISORS, CONSULTANTS OR ANY OTHER PERSON IS AT NNOG’S SOLE RISK. IF AND TO THE EXTENT NNOG SHARES ANY SUCH INFORMATION WITH RESOLUTE, RESOLUTE AGREES THAT SUCH INFORMATION SHALL BE PROVIDED TO RESOLUTE ON THE SAME TERMS THAT RESOLUTE PROVIDES INFORMATION TO NNOG AS SET FORTH ABOVE.

          5.04 If requested by NNOG, Resolute will use its best good faith reasonable efforts (without the payment of consideration) to assist NNOG in its arranging acceptable financing for NNOG’s purchase of its 25% initial interest in the Aneth Assets from CVX. Resolute will also use its best good faith reasonable efforts to introduce NNOG to financing sources and to share information with respect to financial structures that may further NNOG’s ability to finance its acquisitions and operations.

          5.05 To further assist NNOG in its goal of enhancing its operating capability, Resolute will fund on an ongoing basis two scholarships in petroleum engineering and/or petroleum geology for qualified Navajo students for such time as Resolute is operating the Aneth Assets. Scholarships will be granted by representatives of NNOG and Resolute as agreed to among the parties.

          5.06 NNOG shall use its best good faith reasonable efforts to help maintain good relationships among Resolute and its employees, the community and the NN, including areas of cultural sensitivity. NNOG will advise Resolute of all material information of which it becomes aware that could impact the efficient operation of the Aneth Assets or community or employee relations. NNOG shall use its best good faith reasonable efforts to prevent confusion among Resolute employees or the Aneth communities as to Resolute’s authority and role concerning operations on the Aneth Assets.

          5.07 NNOG shall use its best good faith reasonable efforts to expand and develop its operating capabilities and expertise and to enhance its financing sources.

          5.08 NNOG shall use its best good faith reasonable efforts to maintain cooperative efforts among all parties and agencies concerned with operations concerning the Aneth Assets. NNOG shall use its best good faith reasonable efforts to obtain the consents and approvals necessary or convenient for the consummation of the CVX transaction and the efficient execution of future operations concerning the Aneth Assets, including, without limitation, consents and approvals of the NN, the Bureau of Land Management (“BLM”), Bureau of Indian Affairs (“BIA”), and all other authorities having jurisdiction over the Aneth Assets.

          5.09 NNOG will use its best good faith reasonable efforts to cause NN to agree to grant or renew any rights of way that may be needed or useful for the operation and utilization of the Aneth Assets.

ARTICLE VI.
TAX MATTERS

          6.01 Except as provided below concerning New Markets Tax Credits (“NMTC”), NNOG will retain the right to market to third parties or otherwise for its sole benefit any income tax exemptions, allowances, deductions or credits available to it under applicable law arising from its operations. The value of any tax benefits of NNOG that the parties may agree to allocate to Resolute will be treated as revenue to Resolute for purposes of determining Payout.

          6.02 Resolute, as manager of Resolute NAD, LLC, (“RNAD”) is pursuing, at its discretion and expense, an application for an allocation of NMTC under Section 45 D of the Internal Revenue Code and the Community Development Financial Institutions Fund program for energy investments on Native American lands. The allocation of credits will not be earmarked for projects on Navajo lands. Nevertheless, Resolute will direct investments that produce NMTC if an allocation is received by RNAD, to the acquisition of and/or operations on the Aneth Assets if and to the extent such investments can be so directed consistent with law, regulation and the application documents. It is acknowledged that Resolute, as manager of RNAD will consider the advice of the Board of Advisors of RNAD in determining the use of NMTC. Subject to the foregoing, the parties acknowledge that Resolute has ultimate discretion in the pursuit of NMTC, the use thereof and whether to continue such pursuit.

          6.03 To enhance the possibility of obtaining an allocation of tax credits, NNOG has agreed to act as a “controlling entity” with respect to RNAD. NNOG owns a voting membership interest in RNAD. NNOG has provided the necessary control entity information for the NMTC application, and shall provide such supplemental information and cooperation as may be reasonably requested by Resolute to continue pursuing an allocation of NMTC. NNOG shall not be involved in management of RNAD beyond the extent required by the NMTC program, and NNOG will not assume any position involving liability. Resolute will be the manager of RNAD unless and until it is removed as manager in accordance with RNAD’s operating agreement. NNOG may terminate its involvement in RNAD at any time provided it gives 45 days’ advance notice thereof to Resolute and provided NNOG conveys its interest in RNAD to Resolute or Resolute’s designee. Resolute shall defend, indemnify and hold harmless NNOG from any expenses, including reasonable attorneys’ fees, associated with third party claims for damages resulting from NNOG’s ownership of a membership interest in RNAD. Resolute shall have the right to control the defense and settlement of any such claim. If in the opinion of Resolute’s attorney’s or advisors Resolute reasonably determines NNOG’s ownership of an equity interest in RNAD creates a reasonable risk of material liability to Resolute or if it reasonably could impair the obtaining of an allocation of NMTC, upon request of Resolute, NNOG shall convey its interest in RNAD to Resolute or Resolute’s designee in a manner consistent with the NMTC program.

          6.04 If Resolute allocates NMTC for activities in connection with the Aneth Assets, the provisions of Exhibit B shall become operative and legally binding as between Resolute and NNOG. The parties shall then promptly enter into good faith reasonable negotiations with a view to executing definitive agreements consistent with the provisions of Exhibit B within 30 days following notice by Resolute of such allocation. The parties shall restructure the transactions described in Exhibit B as necessary or appropriate in order to achieve the contemplated economic and tax results. In general, if NNOG’s working interests participate in the tax credit program, the benefits of the tax credits would be shared in proportion to the working interests of the parties in the Aneth Assets, and Payout would also be credited with all of such credits received by Resolute. If NNOG’s working interests do not participate in the tax credit program, all such tax credit benefits would go to Resolute in the first instance, but Resolute would apply 25% of these benefits to reduce the exercise price of NNOG’s First Option, and Payout would also be credited with the 75% portion of such credits retained by Resolute. Resolute and NNOG, as appropriate, would be entitled to recover their respective out of pocket costs in pursuing such credits prior to determining the proper sharing or allocation of such tax credits. The foregoing provisions and Exhibit B are intended, and should be construed, to be complementary and mutually consistent. However, in the event of any inconsistency between the two with respect to the New Markets Tax Credit program, the terms set forth in Exhibit B shall control.

ARTICLE VII.
AREAS OF MUTUAL INTEREST

               7.01 The Greater Aneth Field, consisting of the McElmo Creek, Ratherford and White Mesa Units, but excluding the Aneth Unit shall constitute an Area of Mutual Interest (the “GREATER AMI”) between the parties. If either party becomes aware of the opportunity to acquire any right, title or interest in any oil and gas lease, mineral interest, facility, contract or other right or interest in or affecting oil and gas, including, without limitation, any right of way, easement or surface interest used or useful for the production of oil and gas, or any contractual right to acquire such an interest (an “Oil and Gas Interest”) in the GREATER AMI, it shall promptly notify the other party and the parties shall negotiate in good faith exclusively with each other for a period of ninety days in an attempt to agree upon an arrangement to acquire the Oil and Gas Interest with the expectation that they would share the acquisition in proportion to their interests in the Aneth Assets. Neither party shall solicit, entertain, discuss, review, analyze nor respond to any other proposals or requests during the period of exclusive negotiations. Notwithstanding anything herein to the contrary, if a party has not breached its obligations under this Section 7.01 and believes in good faith that further negotiations would not likely result in definitive agreement, such party may give notice to the other party of such circumstance and the obligations of good faith, exclusive negotiations shall terminate fifteen (15) days following such notice. This Section 7.01 shall not prevent a party from taking any action to pursue or capture the acquisition opportunity.

               7.02 The boundaries of the Aneth Unit, as it may be modified, or any successor unit area, shall also constitute an Area of Mutual Interest (the “ANETH AMI”) between the parties. If either party acquires an Oil and Gas Interest in the ANETH AMI it shall notify the other party within 30 days of the acquisition giving full particulars concerning the acquisition, including the price. The other party shall have 15 days within which to elect to require an assignment of an interest in the acquired property proportional to its relative working interest in the Aneth Unit compared to the acquiring party’s working interest in the Aneth Unit. If the non-acquiring party elects to require such an assignment, it shall pay its proportionate share of all acquisition costs in exchange for proper assignments at a closing to be held within 30 days following the election.

               7.03 The GREATER AMI and the ANETH AMI shall terminate upon the consummation of a Sale (as defined in Section 4.01) by Resolute.

ARTICLE X.
DISPUTE RESOLUTION; GOVERNING LAW

          10.01 Dispute Resolution – General.

     (a) Any dispute or difference arising under or out of, in relation to or in any way connected with (i) this Agreement, the Aneth Unit Agreement or Unit Operating Agreement (“JOA”), the ASA any contract or other obligation or right acquired from ChevronTexaco under or on account of the ASA, or any amendment of the foregoing, (ii) any property, right, interest contract or obligation jointly acquired by the parties in the Greater AMI or Aneth AMI, or (iii) any operations, transactions, actions or inactions conducted, arising under or out of, in relation to or in any way connected with any of the items or matters listed in (i) or (ii) above (whether contractual, tortious, equitable, statutory or otherwise including, without limitation, the negotiation, execution, existence, amendment, validity, enforceability, performance, non-performance, breach, termination, interpretation or construction thereof), or the commercial or economic relationship of the parties hereto, and all questions as to whether or how specific disputes are to be resolved pursuant to this Article (the foregoing referred to individually or collectively as “Dispute”) shall be resolved in accordance with the procedures of this Article X. Without limiting the generality of the foregoing, Disputes include disputes over the existence, validity, interpretation or scope of the agreement under which arbitration is sought, and who are proper parties to the arbitration. In any arbitration under this Article, the arbitration panel shall have the power to rule on its own jurisdiction, including any objection to the initial or continuing existence, validity or the effectiveness of the arbitration agreement. For the purposes of challenges to the jurisdiction of the arbitration panel, the arbitration clause shall be considered as separable from any contract of which it forms a part.

     (b) The procedures specified in this Article will be the sole and exclusive procedures for the resolution of Disputes; provided however that, prior to the appointment of the arbitrators, a party may seek a preliminary injunction or other preliminary judicial relief in U.S. District Court in New Mexico if in the judgment of that party such action is necessary to avoid irreparable damage or to preserve the status quo. Despite the initiation of any such judicial proceedings, the parties will continue to participate in good faith in the procedures specified in this Article. Each party is required to continue to perform its obligations under this Agreement pending final resolution of any Dispute. The parties’ commitment to resolve Disputes pursuant to this Article survives the expiration or termination of this Agreement. All deadlines specified in this Article may be extended by mutual written agreement. As between the parties, all applicable statutes of limitation shall be tolled while the procedures specified in this Article are pending and the parties will take all actions, if any, required to effectuate such tolling. The existence of this provision regarding tolling shall not be deemed to imply that the parties have access to court in lieu of the dispute resolution under this Article.

     (c) Except for Disputes over the determination of Fair Market Value under §3.03 of this Agreement (“Value Disputes”), Disputes will be addressed using a three-step sequenced process that includes: (1) direct negotiation as described §10.02, (2) a convening meeting with a mediator as described in §10.03, and (3) submittal to binding arbitration as described in §10.04. Because

the parties have agreed that Value Disputes must be resolved on an expedited schedule, Value Disputes will be finally resolved by arbitration in accordance with the CPR Rules for Non-Administered Arbitration as set forth in §10.05 without formal or preliminary negotiations or steps.

          10.02 Direct Negotiation. The parties shall attempt in good faith to resolve any Dispute promptly by negotiation between executives who have authority to settle the controversy and who are at a higher level of management than the persons with direct responsibility for administration of the relevant contracts. Either party may give the other party written notice of any Dispute that has not been resolved in the normal course of business. Within 10 days after delivery of the notice, the receiving party shall submit to the other a written response. The notice and response shall include: (a) a statement of that party’s position and a summary of arguments supporting that position, and (b) the name and title of the executive who will represent that party and of any other person who will accompany the executive. Within 20 days after delivery of the initial notice, the executives of both parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the Dispute. All reasonable requests for information made by one party to the other will be honored. All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

          10.03 Convening Meeting. If the Dispute has not been resolved by negotiation as provided herein within 30 days after delivery of the initial notice of negotiation, or if the parties failed to meet within 20 days after delivery, the Parties agree to attend and participate in a convening meeting (“Convening”), facilitated by a knowledgeable mediator, to discuss use of alternate dispute resolution methods to resolve the Dispute. Either party may demand a Convening regarding a Dispute by sending written notice to the other party. Within 5 days after the date of such notice, the receiving party shall submit a written response to the other. For such a Convening, the Parties agree that they will cooperatively and jointly select the mediator, schedule a Convening in Santa Fe, New Mexico at a mutually acceptable time, and will equally share the mediator’s fees. Each Party agrees to attend such a meeting for at least four hours, but is free to withdraw from the Convening after attending for that time period. The parties anticipate that such a Convening, among other things, would include discussion of the following: (a) the mode of proceeding further (for example, mediation, neutral evaluation, mini-trial, etc.); (b) a procedure and schedule for exchange of documents and other information related to the Dispute; (c) ground rules and a schedule for conducting the selected mode of proceeding; and, (d) selection and compensation of the neutral evaluator (if any). Each party is required to continue to perform its obligations under this Agreement pending final resolution of any Dispute.

          10.04 Arbitration of Disputes Other than Value Disputes.

     (a) If the Dispute has not been amicably resolved within 30 days after the initial notice for a Convening, or if either party will not participate in Convening, the Dispute shall be finally resolved by arbitration in accordance with the CPR Rules for Non-Administered Arbitration then currently in effect (“CPR Rules”), by three arbitrators of whom each party shall appoint one in accordance

with the ‘screened’ appointment procedure provided in CPR Rule 5.4; provided, however, that if one party fails to participate in either the negotiation or mediation as agreed herein, the other party can commence arbitration prior to the expiration of the time periods set forth above. In the event of any conflict between the CPR Rules and the arbitration procedures set forth in this Section, the arbitration procedures set forth in this Section shall govern and control. The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§1–16, and judgment upon the award rendered by the arbitrators may be entered as provided in §10.06.

     (b) In any Dispute submitted to arbitration by NNOG, the arbitration hearing shall take place in a location selected by Resolute. In any Dispute is submitted to arbitration by Resolute, the arbitration hearing shall take place in a location selected by NNOG.

     (c) The Arbitrators shall apply the substantive law of the State of New Mexico exclusive of its conflict of law rules. The Arbitrators shall have authority to award any remedy or relief that a court of the State of New Mexico could order or grant, subject to the limitation that the only form of damages that may be awarded are compensatory damages based in contract law. Therefore, each party hereby irrevocably waives any damages (i) in excess of compensatory damages, including a waiver of any indirect, exemplary, punitive or multiple damages, (ii) for lost profits or business opportunity, (iii) arising in consumer protection statutes, and (iv) based in tort rather than contract law.

     (d) The following procedures will guide arbitration conducted under this Section:

    (i) Pre-hearing conference. The parties and arbitrators will schedule a comprehensive pre-hearing conference to be completed as soon as practicable after the selection of arbitrators that is intended to result in the issuance by the arbitrators of a order that specifically identifies the issues and claims submitted to arbitration, and establishes dates for the hearing and actions to be completed prior to the hearing.

    (ii) Discovery. Consistent with the expedited nature of arbitration, each party will, upon the written request of the other party, promptly provide the other with copies of the documents relevant to the issues raised by any claim, cross claim or counter claim. Any dispute regarding their production, or the scope thereof, shall be determined by the chair of the panel, which determination shall be conclusive. The arbitrators shall permit and facilitate such additional discovery as they determine is appropriate in the circumstances, taking into account the needs of the parties and the desirability of making discovery expeditious and cost-effective. Such discovery may include pre-hearing depositions, particularly depositions of witnesses who will not appear personally to testify,

if there is a demonstrated need therefor. The arbitrators may issue orders to protect the confidentiality of proprietary information, trade secrets and other sensitive information disclosed in discovery.

    (iii) Time limitations and management of proceedings. The arbitration proceedings shall be conducted in an expeditious manner and, to the extent possible, with the goal of having the final award rendered within 45 days after the selection of the arbitrators has been completed. The Arbitrators shall actively manage the proceedings as they deem best so as to make the proceedings fair, expeditious, economical, and less burdensome than litigation. The arbitrators are empowered to impose reasonable time limitations for each phase of the proceeding including, but not limited to, limitations on the time allotted to each party for the presentation of its case and rebuttal.

    (iv) Provisional and equitable remedies. The arbitrators may, in the course of proceedings, order any provisional remedy or conservatory measure, including but not limited to attachment, specific performance, preliminary injunction or the deposit of specified security, which they consider to be necessary, just and equitable. The failure of a party to comply with such an interim order, after due notice and opportunity to cure such noncompliance, may be treated by the arbitrators as a default and all or some of the claims or defenses of the defaulting party may be stricken and partial or final award entered against such party, or the arbitrators may award such lesser sanctions as they deem appropriate. A request for interim or provisional relief to a court under §10.01(b) shall not be deemed incompatible with the agreement to arbitrate or as a waiver of that agreement.

    (v) Attorney’s fees. The parties agree that the prevailing party in any Dispute finally resolved by arbitration is entitled to an award of the reasonable legal fees, costs, expert fees, and expenses (collectively “Fees”) incurred in the arbitration provided that such award of Fees may not exceed the amount of the Fees incurred by the losing party in the arbitration process. The parties further agree that the award of Fees made in the arbitration may include both: (a) Fees incurred in the arbitration, and (b) Fees incurred in any litigation concerning the Dispute (including but not limited to litigation to compel arbitration or stay court proceedings).

     (e) Award. The parties intend that the award will be a reasoned award that will be issued within thirty days after the completion of the taking of

evidence, argument by counsel before the panel, and submission of any post-hearing filings.

     (f) Consolidation. The parties wish to avoid multiple arbitration cases in which similar evidence is presented. The parties agree that the following factors bear upon whether independent arbitration proceedings should be consolidated: the procedural status of the various proceedings; the effect and cost of conducting multiple rather than a single arbitral proceedings; whether there are one or more common questions of law or fact in the multiple proceedings; and whether the interests of justice, judicial economy and expedition would be served by consolidation. Therefore, except as provided in §10.05(f), either party may move to consolidate any arbitration proceeding under this §10.4 with another arbitration or arbitrations under this Section. The arbitrators in the first initiated arbitration proceeding shall receive and rule upon motions or requests to consolidate proceedings, and shall also determine the venue for the consolidated proceeding. The parties agree to cooperate to the extent possible on any consolidation of proceedings under this Section with an arbitration proceeding under the ASA where the factors above support consolidation.

               10.05 Special Arbitration Procedures for Value Disputes.

     (a) Value Disputes shall be finally resolved by arbitration in accordance with the CPR Rules as modified in this Agreement. The arbitration of Value Disputes shall be governed by the Federal Arbitration Act, 9 U.S.C. §§1–16, and judgment upon the award rendered by the arbitrator may be entered as provided in §10.06. The arbitrator shall apply the substantive law of the State of New Mexico exclusive of its conflict of law rules.

     (b) Because special expertise is needed to adjudicate a Value Dispute, a nationally recognized energy valuation firm, acting through one of its principals as selected by such firm, will serve as the single neutral and impartial arbitrator (“Value Arbitrator”). Within 5 days of the Market Value Notice served under Section 3.03, the parties will confer and attempt to agree upon one of the following nationally recognized energy valuation firms to serve as arbitrator: Randall & Dewey; Petrie Parkman & Company; or Albrecht & Associates. A successor of any such company that generally has continued the business of the predecessor company shall be considered the same as the predecessor company. Changes of name of any of the above companies shall not affect the company’s qualification as an arbitrator. Value Arbitrators must comply with the CPR Rules, including Rule 7 concerning arbitrator independence and impartiality. If the parties cannot reach agreement on the identity of the arbitrator or if any other dispute arises concerning the selection of the Value Arbitrator, the Value Arbitrator will be promptly selected by the President of the CPR Institute or his designee (“CPR President”).

     (c) The sole issue submitted to, and to be ruled upon in the award by, the Value Arbitrator is the determination of Fair Market Value as defined in §3.03.

     (d) Although the Value Arbitrator has expertise to determine Fair Market Value, the Value Arbitrator may be unfamiliar with the details of arbitration and the CPR Rules. Therefore, to assist the Value Arbitrator with questions concerning arbitration process, the CPR President will appoint from the appropriate CPR Panel a single person who will advise and assist the Value Arbitrator as needed to ensure that CPR Rules are understood and followed, including those provisions concerning neutrality and impartiality. (“CPR Advisor”).

     (e) The Value Arbitrator will determine the process to be used in the arbitration of the Value Dispute so as to render an award that determines the Fair Market Value within 30 days of selection of identity of the Value Arbitrator. The fees and expenses of the Value Arbitrator, the CPR Advisor and CPR will be shared equally by the parties. Each party shall bear its own legal fees incurred in the Value Dispute.

     (f) Because Value Arbitration arbitrations under this §10.05 require prompt resolution, no arbitration conducted under this §10.05 will be joined with any other arbitration.

          10.06 Venue, Jurisdiction, Waiver of Defenses, Governing Law.

     (a) NNOG irrevocably agrees that, to the extent that it has or hereafter may acquire any right of immunity against Resolute or its successors and assigns, whether characterized as sovereign immunity or otherwise, from any legal proceedings to resolve a Dispute, whether in the courts of the United States of America, any State of the United States of America, or the Navajo Nation, or in an arbitration proceeding, or elsewhere, including, without limitation, immunity from service of process, immunity from jurisdiction or judgment of any court or tribunal, immunity from execution of judgment and immunity of any of its property from attachment prior to entry of judgment, or from attachment in aid of execution upon a judgment, NNOG expressly, unconditionally and irrevocably waives any such immunity and consents and submits to arbitration pursuant to §10.04 or §10.05, as applicable, and further consents to be sued to the extent and in the manner such suit is authorized by §10.06(b).

     (b) NNOG hereby expressly, unconditionally and irrevocably waives any immunity described in §10.06(a) and any right of exhaustion of tribal remedies, with respect to any suit, action or other proceeding brought in the United States District Court for the District of New Mexico in connection with any Dispute between NNOG and Resolute for the limited purpose of (1) compelling arbitration, (2) granting preliminary relief described in §10.01(b) and/or (3) enforcing an arbitration award, and consents to the jurisdiction of such

federal court for such purposes. NNOG hereby waives and agrees not to assert by way of motion or as a defense or otherwise in any such suit or proceeding (i) any claim that it is not subject to the personal jurisdiction of such federal court (provided process is served pursuant to law), and (ii) that such suit, action or proceeding is brought in an inconvenient forum or that venue is improper. In the event that the above-named federal court has determined that it does not have jurisdiction over such matters brought before it, or at the election of Resolute, NNOG hereby expressly, unconditionally and irrevocably waives any immunity described in §10.06(a) with respect to an action or other proceeding in the state courts of the State of New Mexico for such relief related to arbitration and consents to the jurisdiction of such court for such purposes.

     (c) Any judgment against NNOG or Resolute resulting from arbitration as authorized by §10.04 or §10.05, as applicable, may be satisfied out of any of such party’s assets.

     (d) This Agreement shall be governed by and construed, interpreted and applied in accordance with the laws of the State of New Mexico, excluding any choice of law rules or conflicts of law principles which would refer the matter to the laws of another jurisdiction.

The following terms and conditions of purchase and sale shall be binding and enforceable as an agreement of purchase and sale as a part of the Cooperative Agreement between Resolute Natural Resources Company (“Resolute”) and Navajo Nation Oil and Gas Company (“NNOG”) dated effective October 22, 2004 (the “Cooperative Agreement”) upon the proper and timely exercise of any of the Options of NNOG set forth in Articles III and IV of the Cooperative Agreement. Capitalized terms used herein and not defined here have the meaning defined in the main body of the Cooperative Agreement.

Assets		As to each Option, an undivided 10% (or lesser percentage as elected by NNOG in its notice of exercise) of an undivided and proportionally reduced 75% of the Aneth Assets as defined in the Agreement,
Purchase Price		Wire transfer of immediately available US Dollars in the amount of the Fair Market Value of the assets subject to the Option exercise as of the effective date of the assignment as set forth below, subject to adjustments as set forth below. NNOG shall provide to Resolute a fair and reasonable allocation of value among the separate leases and other assets at the time of exercise of the Option.
Effective Date		With respect to the exercise of each Option, the effective date of the assignment shall be the date that the Payout relevant to the Option involved occurred, provided that for accounting convenience, such date shall be deemed to be 12:01 a.m. local time at the location of the Aneth Assets on the first day of the month during which such Payout occurred.
Due Diligence and Disclosure		Following notice by Resolute that an option may be exercised and until the date of such exercise, Resolute shall provide NNOG access to all of the Aneth Assets and pertinent records for the purpose of allowing NNOG to perform such title, environmental and other due diligence as NNOG desires. Resolute shall not

		intentionally withhold any material information concerning the condition of or circumstances concerning the assets requested by NNOG. NNOG may request that any adverse condition or circumstance be taken into account in determining Fair Market Value, provided, however, that any such determination shall be made by the arbitrators if the parties fail to agree on Fair Market Value.
Purchase Price Adjustments		Same as in the ASA Section 2.4, 2.5 and 12.6 except there shall be no adjustments for title matters, environmental matters, casualty losses or other problems and the final adjustment shall be completed within 90 days following closing.
Closing		The Closing of the purchase and sale with respect to each exercise of an Option shall take place on the first business day following the fourteenth day after the date the notice of exercise with respect to that Option is deemed to have been given pursuant to the Cooperative Agreement. The Closing with respect to any Option shall take place at the offices of Resolute in Denver, Colorado.
Warranties and Representations		The purchase and sale with respect to any Option shall be made WITHOUT WARRANTY OR REPRESENTATION OF ANY KIND, EXPRESS OR IMPLIED, except that Resolute shall warrant title to the interest transferred as against all interests arising by, through or under Resolute, but not otherwise.
Assumption of liabilities		As to each portion of the Aneth Assets acquired by NNOG pursuant to an exercise of an Option, NNOG shall assume and defend, indemnify and hold harmless Resolute and its affiliates from (i) a proportional share (proportional to the share of the Aneth Assets acquired by NNOG pursuant to the exercise of its Option) of the obligations, liabilities and indemnities in favor of ChevronTexaco and its affiliates under the ASA and (ii) a proportional

		share of all other contracts, obligations, claims, losses, limitations, reservations and burdens associated with the Aneth Assets, whether associated with operations or ownership before on or after the effective date of the transfer.
Forms of Assignment		General Assignment in the same form as Exhibit B to the ASA, modified to be consistent with these and the other provisions of the Cooperative Agreement. Resolute shall also provide assignments on proper Navajo, BIA and BLM forms.
Taxes		Same as Section 5.1 of the ASA.
Preferential Purchase Rights		Same as Section 10.2 of the ASA, modified to be consistent with the provisions of the Cooperative Agreement set forth herein.
Dispute Resolution		The provisions of Article X of the Cooperative Agreement apply to the purchase and sale obligations and to any assignments or other documents or instruments delivered in connection with the exercise of any Option.
Further Assurances		Before and after Closing each party shall execute, acknowledge, and deliver all documents, and take all such acts which from time to time may be reasonably requested by the other party in order to carry out the purposes and intent of these provisions of the Cooperative Agreement.
Termination		The agreement of purchase and sale arising through the exercise of an option may be terminated by (i) Resolute if through no fault of Resolute NNOG fails to close the purchase transaction within 5 business days following the last permitted closing date pursuant to the provisions above or (ii) NNOG, if through no fault of NNOG Resolute fails to close the transaction within 5 business days following the last permitted closing date pursuant to the provisions above. Such termination shall not affect the remedies, if any, otherwise available to the non-breaching party for any breach by

		the other party. The parties acknowledge the provisions of Section 4.02 making void, under the circumstances therein provided, the exercise of the option and the provisions of purchase and sale arising therefrom.
