(5) an amount equal to the actual purchase price paid for any oil, gas and/or other mineral leases, leasehold estates and interests, mineral, royalty, overriding royalty, production payment, reversionary, net profit, contractual leasehold, easements, rights of way and other similar rights, estates, or interests acquired by the Petro-Hunt Parties located within the boundaries of the plat or map set forth as Exhibit “A”, Part III attached hereto after the date of this Agreement but before the Closing (the “Additional

(6) any other amount agreed upon by the Petro-Hunt Parties and Buyer.

(b) The Purchase Price shall be adjusted downward by the following:

(5) an amount equal to the value of that portion of the Properties with respect to which the Petro-Hunt Parties have produced a share of gas in excess of its ownership percentage and the Petro-Hunt Parties are obligated to reduce their share of production under a gas balancing agreement or similar arrangement to allow under-produced parties to come back into balance (“Over Production”) (the value of such Over Production to be based on the price which could have been received by the Petro-Hunt Parties on the dates(s) that such Over Production occurred; and

(6) any other adjustment provided for under this Agreement, or other amount agreed upon by the Petro-Hunt Parties and Buyer in writing.

(c) Notwithstanding anything to the contrary set forth in this Agreement, any net reduction or net increase in the Purchase Price shall be applied to reduce or increase the amount of cash and shares of Preferred Stock to be delivered according to Section 2.01(b) in the same proportion as set forth in Section 2.01(b) above.

(d) To the extent that any Properties are excluded from the assets and properties to be owned by Petro-Hunt FB/M Successor or Pillar FB/M Successor at the effective time of the Mergers in accordance with the terms and provisions of this Agreement, then any other positive or negative adjustments to the Purchase Price relative to such excluded Properties shall not be applied.

2.03 Allocation of Purchase Price.

For purposes hereof, producing Wells within the Properties will be deemed to include a 180-acre tract allocable to such Well (an “Allocated Unit”); and (i) the “Undeveloped Leases” shall mean the remainder of the Leases (or portions thereof) which are not allocated or included in an Allocated Unit that is attributable to a Well; (ii) “Per Net Mineral Acre Price” is the per net mineral acre price or value set forth for the different areas and regions described in Exhibit “D” attached hereto, and (iii) “net mineral acre” shall mean the Petro-Hunt Parties’ undivided Working Interest in the leasehold estate created by a Lease, multiplied by the number of gross acres covered by such Lease, multiplied by the lessor’s undivided interest in the oil and gas mineral fee estate in the lands covered by such Lease. For the purpose of making the requisite Tax filings under the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations thereunder, the Petro-Hunt Parties and Buyer agree to allocate the Purchase Price (as adjusted pursuant to the provisions hereof) among the assets of the Petro-Hunt FB/M

Successor and Pillar FB/M Successor, as provided in the Allocated Value. The Petro-Hunt Parties and Buyer each agree to report the federal, state and local income and other Tax consequences of the transactions contemplated herein, and to prepare and file all Tax Returns in a manner consistent with the terms of the Allocated Value and shall not take any position inconsistent therewith upon examination of any such Tax Return, in any refund claim, in any litigation, investigation or otherwise unless required to do so by applicable law. The Petro-Hunt Parties and Buyer shall confer and cooperate on any revisions to the Allocated Value, including reporting any matters that require updating (including adjustments to the Purchase Price) to be consistent with the Allocated Value.

2.04 Tax Treatment of Purchase of Membership Interests. The sale and purchase of the Membership Interests will be treated as a sale of the assets of Petro-Hunt FB/M Successor and Pillar FB/M Successor, as applicable, for United States federal income Tax purposes, as well as all applicable state and local income Tax purposes and shall prepare all Tax Returns in a manner consistent with such Tax treatment and shall not take any Tax position inconsistent therewith.

ARTICLE IV.

Covenants

4.01 Covenants of Petro-Hunt Parties. The Petro-Hunt Parties covenant and agree with Buyer that:

(a) Buyer Access. Prior to the Closing, the Petro-Hunt Parties will (i) provide access to the Properties and the Records to Buyer and its representatives, for inspection and evaluation, and (ii) make available to Buyer for examination in a virtual data room or at the office of the Petro-Hunt Parties in Dallas, Texas, title and other records, books, files (including, without limitation, land, lease, title, title opinion, production, operations and regulatory files) and information relating to the Properties, insofar as the same are in possession or reasonable control of the Petro-Hunt Parties. The Petro-Hunt Parties will cooperate with Buyer in Buyer’s efforts to obtain, at Buyer’s sole expense, any additional information relating to the Properties that Buyer may consider useful in this transaction; provided, however, that the Petro-Hunt Parties make no assurances or representations herein to Buyer as to the completeness or accuracy of any of the records of the Petro-Hunt Parties made available to Buyer hereunder. Rather, Buyer should rely entirely on its own examination of the

records of the Petro-Hunt Parties and its own independent due diligence and other investigations of the Properties, as well as on the representations, warranties and covenants of the Petro Hunt-Parties in this Agreement and the Exhibits and Schedules attached hereto. In the event the Petro-Hunt Parties advise Buyer that it will withhold or be unable to deliver any information as defined herein, the Petro-Hunt Parties will (a) identify to Buyer the general nature or type of information that is being withheld; and (b) use commercially reasonable efforts to obtain consents or approvals necessary to permit disclosure to Buyer, only insofar as the Petro-Hunt Parties may do so without violating legal constraints or any contractual prohibition, obligation, other confidentiality requirement, or other commitment of the Petro-Hunt Parties to a third party. Promptly after execution of this Agreement, the Petro-Hunt Parties will provide to Buyer for inspection any and all historical file information in the possession or control of the Petro-Hunt Parties regarding crude oil, produced water, or Hazardous Materials spilled or disposed of on or off-site of the Properties and the locations thereof; pits and pit closures; substance, materials or equipment burials; land farming; land spreading; underground injection; solid waste disposal sites; and environmental permits and Spill Prevention Control and Countermeasure Plans. The Petro-Hunt Parties are not obligated to commission any updated abstracts, title opinions or additional title information, but shall provide all of the same that is in the possession (or reasonable control) of the Petro-Hunt Parties and shall cooperate with Buyer in Buyer’s efforts to obtain, at Buyer’s reasonable expense, such additional title information as Buyer may reasonably deem prudent. To facilitate Buyer’s full evaluation of the Environmental Condition of any of the subject Properties, as the law or third party rights may dictate, and consistent with Section 5.05 hereof, the Petro-Hunt Parties will permit representatives of Buyer to make such environmental tests on the Properties as may be within immediate dominion, control and authority of the Petro-Hunt Parties, including Phase I environmental assessments. Buyer may not conduct Phase II environmental testing or other invasive surface or subsurface testing on the Properties without the prior written consent of the Petro-Hunt Parties, which consent will not be unreasonably withheld. The Petro-Hunt Parties will cooperate with Buyer in seeking third party operators’ consents to inspect and test on non-operated Properties; provided, however, that there is no assurance that such activities will be permitted by such third party operators. To the extent consent is withheld or refused by Petro-Hunt Parties as to the Properties, the affected Properties may be deemed to be burdened by an Environmental Defect for purposes of this Agreement, and Buyer will have the option to have the affected Properties excluded from this Agreement. If such option is exercised by Buyer, the Purchase Price will be reduced by the Allocated Values of any excluded Properties. The Petro-Hunt Parties shall permit Buyer, at Buyer’s sole expense, to inspect and photocopy all environmental information and records relevant to the Properties under this Section 4.01(a) during reasonable business hours so long as this Agreement is in effect; provided, however, that in the event the Petro-Hunt Parties advise Buyer that it will withhold or be unable to deliver any environmental information hereunder, because the Petro-Hunt Parties cannot do so without violating any legal constraints or contractual prohibition,

obligation, other confidentiality requirement, or other commitment to a third party; and, as to such withheld environmental information, the Petro-Hunt Parties will (a) identify to Buyer the general nature or type of information that is being withheld; and (b) use commercially reasonable efforts to obtain consents or approvals necessary to permit disclosure to Buyer. Notwithstanding any of the foregoing, EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PETRO-HUNT PARTIES MAKE NO WARRANTY OR REPRESENTATION OF ANY KIND, EITHER EXPRESS OR IMPLIED, WRITTEN OR ORAL, AS TO THE RECORDS, INCLUDING ANY REPRESENTATION OR WARRANTY AS TO THE ACCURACY AND COMPLETENESS OF THE RECORDS. Except with regard to statements, representations and warranties of the Petro-Hunt Parties in this Agreement, Buyer acknowledges that any other conclusions drawn from the Records and other information concerning the Properties are the result of its own independent review and judgment.

(b) Petro-Hunt Parties Cooperation. The Petro-Hunt Parties acknowledge that, following execution of this Agreement, Buyer may enter into debt facilities or engage in offerings of securities requiring registration under the Securities Act and the need for audited financials relating to the Properties. Therefore, from and after the date of this Agreement (including from time to time after the Closing Date), the Petro-Hunt Parties and to the extent appropriate their affiliates, employees, representatives, agents and accountants will promptly provide such cooperation and assistance to Buyer or HRC as they may reasonably request (i) in connection with the preparation of financial statements, reports and filings relating to the transactions contemplated in this Agreement that Buyer or HRC have determined in good faith are required under applicable laws, rules and regulations, including, without limitation, the rules and regulations of the SEC and the New York Stock Exchange (“NYSE”), and (ii) to respond to any inquiries by regulatory authorities, including the SEC and NYSE, relating to the foregoing financial statements, reports and filings. Without limiting the foregoing, such cooperation shall include providing HRC and its employees, representatives, agents and external accountants, with access to, and the right to copy, relevant books, records, files, and documentation in the possession or under control of such the Petro-Hunt Parties or their employees, representatives, agents and accountants (except for those proprietary and confidential tax, engineering and accounting records otherwise excluded from this Agreement). In so doing, the Petro-Hunt Parties will make appropriate persons available to answer questions and execute and deliver or cause to be executed and delivered any reasonable and customary external audit firm representation letters as may be reasonably requested by Buyer or HRC. Buyer will reimburse all reasonable out of pocket expenses incurred in complying with this Section 4.01(b) incurred by the Petro-Hunt Parties or their affiliates.

(c) Certain Pre-Closing Covenants Regarding Properties. From the date of this Agreement and continuing until Closing, the Petro-Hunt Parties (i)

will cause the Properties to be operated and maintained in a good and workmanlike manner consistent with prior practices, and will pay or cause to be paid all costs and expenses in connection therewith, (ii) will not abandon any Properties, nor will the Petro-Hunt Parties assign, convey, transfer, mortgage or hypothecate any of the Properties (other than the sale of oil and gas from or allocable to the Properties sold in accordance with the applicable Contracts; and other than granting a lien, mortgage or security interest as required under the credit facility of the Petro-Hunt Parties, insofar as such liens, mortgages or security interests are fully released at or prior to Closing), (iii) will maintain insurance now in force applicable to the Properties, (iv) will comply in all material respects with and make filings required by all applicable federal, state and local laws, rules and regulations, including, without limitation, all of the rules, regulations and orders of the North Dakota Industrial Commission (“NDIC”) that are applicable to the Petro-Hunt Parties and the Properties, (v) will perform and comply with all of the material covenants and conditions contained in the Leases, Contracts and agreements relating to the Properties, and (vi) will pay all taxes and assessments due and payable with respect to the Properties prior to the Closing Date. Except for expenditures under AFEs identified on Schedule 3.01(k) hereto or emergency operations (incurred in connection with unforeseen circumstances that the Petro-Hunt Parties in good faith believe involves bodily harm, or imminent loss of life or property), and only insofar as such expenses the Petro-Hunt Parties notify Buyer of in writing within five (5) business days after incurring the same, from the date of this Agreement until the Closing, without Buyer’s written consent (which Buyer will not unreasonably withhold, and to which Buyer will use its commercially reasonable efforts to respond to within three (3) business days of written request by the Petro-Hunt Parties for same), the Petro-Hunt Parties will not conduct or authorize any operation on the Properties with costs in excess of $100,000 as to their portion of any single project on the Properties, or which require AFE approval by working interest owners under applicable operating agreements of an expenditure of, over $100,000 as to their portion thereof.

(d) No New Contracts. From the date of this Agreement and continuing until Closing, without the prior written consent of Buyer (which Buyer will not unreasonably withhold, and to which Buyer will use its commercially reasonable efforts to respond to respond within three (3) business days of written request by the Petro-Hunt Parties for same), and with due consideration of Schedule 3.01(k) hereto, Petro-Hunt Parties shall not enter into any new material agreements or commitments with respect to the Properties, unless such contract is both consistent with past practices and is a contract that can be terminated upon not more than 90 days prior written notice without penalty or payment for such termination; and the Petro-Hunt Parties will not materially modify or terminate any of the Leases, Contracts or other agreements relating to the Properties, and will not voluntarily compromise or waive any amounts or claims payable to the Petro-Hunt Parties due to any casualty loss or any pending or threatened taking related to the Properties.

(e) Consents. Prior to the Closing Date, the Petro-Hunt Parties will make all necessary requests of third parties to comply with applicable Leases, Contracts and agreements, for consents required to be given or waived, and for preferential rights required to be exercised or waived other than any such consents that are customarily obtained following the closing in transactions of this nature; provided, however, nothing contained in this Section 4.01(e) shall require the Petro-Hunt Parties to pay money in order to obtain such consent.

(f) Maintain Relationships. During the period from the date of this Agreement to the Closing Date, the Petro-Hunt Parties shall use commercially reasonable efforts to maintain its relationships with all suppliers, customers and others having business relationships with the Petro-Hunt Parties with respect to the Properties so that such relationships will be preserved for Buyer on and after the Closing Date.

4.02 Covenants of Buyer and HRC. Buyer covenants and agrees with the Petro-Hunt Parties that, prior to Closing:

(a) Buyer shall maintain its corporate status and to assure that as of the Closing, it will not be under any material corporate, legal or contractual restriction that would prohibit or delay the timely consummation of this transaction.

HRC shall use its reasonable best efforts to furnish the information required in and to respond to any comments made by the SEC or the staff of the SEC on the Proxy Statement. HRC shall, as promptly as practicable after filing and the conclusion of SEC review of the Proxy Statement, if any, mail the Proxy Statement to its stockholders and hold a meeting of its stockholder to vote upon the Proposals as soon as practicable after the mailing of the Proxy Statement.

In the event that the approvals necessary to permit the Preferred Stock to be converted into Common Stock of HRC are not obtained at such special stockholders meeting, HRC shall include a proposal to approve (and the Board of Directors shall recommend approval of) such issuance at a meeting of its stockholders no less than once in each subsequent annual period beginning on January 1, 2013 and ending on the earlier of (1) the date such approval is obtained or made, or (2) December 31, 2020.

After such appointment, so long as the Petro-Hunt Parties beneficially own (as determined in accordance with Rule 13d-3 under the

Exchange Act) at least 5% of the outstanding shares of Common Stock (including for this purpose shares of Common Stock issuable upon conversion of the Preferred Stock), HRC will be required to recommend to its stockholders the election of the Board Representative at HRC’s annual meeting, subject to satisfaction of all legal and governance requirements regarding service as a director of HRC and to the reasonable approval of the Nominating and Governance Committee of the Board of Directors (such approval not to be unreasonably withheld or delayed), to the Board of Directors.

(g) From the date hereof to the Closing, HRC shall not grant to any other person the right, contractual or otherwise, to cause HRC to register under the Securities Act any shares of HRCs common stock with registration rights that interfere with the registration rights of the Petro-Hunt Parties pursuant to the Registration Rights Agreement in substantially the form attached hereto as Exhibit “F”.

(c) To the extent legally permissible and desirable, the Petro-Hunt Parties and Buyer will reasonably cooperate and cause their respective affiliates, officers, employees, agents, auditors and representatives to reasonably cooperate in preparing and filing all Tax Returns, including maintaining and making available to each other all records necessary in connection with Taxes.

(1) is free and clear of liens, mortgages, or encumbrances, other than Permitted Encumbrances;

(2) with respect to each Well (and associated Allocated Unit), (i) obligates the Petro-Hunt Parties (throughout the life of the applicable Leases) to bear costs and expenses relating to the maintenance, development and operation of such Well in an amount not greater than the Working Interest set forth on Exhibit “C” with respect to such Well, unless there is a corresponding and proportionately equal increase in the Net Revenue Interest attributable to such Well (and associated Allocated Unit) and (ii) entitles the Petro-Hunt Parties (throughout the life of the Leases) to a Net Revenue Interest of not less than the Net Revenue Interest set forth for such Well on Exhibit “C”;

(4) with respect to each Undeveloped Lease, results in the Petro-Hunt Parties owning not less than the number of net mineral acres attributable to such Undeveloped Lease (as to the depths set forth on Exhibit “A”, Part I, and excluding, for purposes hereof, net mineral acres allocable to the Allocated Units for the Wells) equal to the net mineral acres for such Undeveloped Lease set forth on Exhibit “A”, Part I.

5.02 Permitted Encumbrances.

As used herein “Permitted Encumbrances” means the following items relating to the Properties, provided that they do not operate to (i) increase the Working Interest of Petro-Hunt Parties set forth on Exhibit “C” or Exhibit “A”, Part I, as applicable, for any of the Properties without a corresponding increase in the applicable Net Revenue Interest, or (ii) decrease in the Net Revenue Interest of Petro-Hunt Parties set forth on Exhibit “C” or Exhibit “A”, Part I, as applicable, for any Property:

(l) such Title Defects or other defects as Buyer has waived in writing.

5.03 Title Defect.

A Property shall be deemed to have a “Title Defect” if the Petro-Hunt Parties do not have Defensible Title thereto. Notwithstanding the foregoing, none of the following shall be considered a Title Defect:

(a) defects in the chain of title consisting of the mere failure to recite marital status in a document or successors of heirship proceedings in a document, unless Buyer provides affirmative evidence that such failure or omission has resulted in another party’s actual and superior claim of title to the relevant Property;

(b) lack of a survey, unless a survey is expressly required by applicable laws or applicable contracts or agreements;

(g) defects based solely on the existence of prior oil and gas leases relating to the Lands that have expired and are no longer in force and legal effect but have not been released of record.

5.04 Defective Interests and Environmental Defects.

(a) As used herein “Defective Interest” means

(1) that portion of a Property affected by a Title Defect; or

(2) that portion of the Properties adversely affected by the default of the Petro-Hunt Parties, or any other party, under an obligation of the Leases or Contracts.

(b) As used herein, “Title Defect Value” shall mean, with respect to a Defective Interest, the amount by which the value of such Defective Interest is impaired as a result of the existence of one or more Title Defects, which amount shall be determined as follows:

(1) If the Title Defect results from the existence of a lien or encumbrance (other than a Permitted Encumbrance), the Title Defect Value shall be an amount sufficient to discharge such lien, not to exceed the Allocated Value of the Defective Interest.

(2) If the Title Defect is based on a deficiency in the net mineral acres of the Petro-Hunt Parties in an Undeveloped Lease from that set forth on Exhibit “A”, Part I for such Undeveloped Lease, then the Title Defect Value shall be an amount equal to the applicable Per Net Mineral Acre Price for such Undeveloped Lease multiplied by the number of net mineral acres the Petro-Hunt Parties are so deficient in such Undeveloped Lease.

(3) If the Title Defect is based on a deficiency in the Net Revenue Interest of the Petro-Hunt Parties in a Defective Interest from that set forth for such Defective Interest on Exhibit “A”, Part I or Exhibit “C”, as applicable, then the Title Defect Value shall be an amount equal to the Allocated Value for such Defective Interest multiplied by the difference of (a) 1 minus (b) a fraction, the numerator of which is the actual Net Revenue Interest of the Petro-Hunt Parties in such Defective Interest, and the denominator of which is the Net Revenue Interest for such Defective Interest set forth in Exhibit “A”, Part I or Exhibit “C”, as applicable.

(4) If the Title Defect results from any matter not described in paragraphs (1), (2), or (3) above, the Title Defect Value shall be an amount equal to the difference between the value of the Defective Interest with such Title Defect and the value of such Defective Interest without such Title Defect (taking into account the Allocated Value of such Defective Interest); provided, however, that if such Title Defect is reasonably susceptible of being cured as provided in this Agreement, the Title Defect Value shall be the reasonable cost and expense of curing such Title Defect, if less, and such Title Defect Value shall never exceed the Allocated Value of such Defective Interest.

(5) The Title Defect Value with respect to a Defective Interest shall be determined without duplication of any costs or losses included in another Title Defect Value hereunder. For example, but without limitation, if a lien affects more than one Defective Interest or the curative work with respect to one Title Defect results (or is reasonably expected to result) in the curing of any other Title Defect affecting the same or another Defective Interest, the aggregate amount necessary to discharge such lien or the cost and expense of such curative work shall only be considered once with respect to all applicable Title Defect Values and Defective Interests.

(6) The Title Defect Value attributable to a Defective Interest shall not exceed the Allocated Value of such Defective Interest. All Title Defect Values and related Purchase Price adjustments shall be made without duplication.

(c) Environmental Defects and Environmental Defect Value. As used herein “Environmental Defect” means any of the following conditions associated with a Property: (1) Noncompliance by the Petro-Hunt Parties with applicable Environmental Laws (defined in Section 8.04 below), or (2) any Environmental Condition that exists on, at or under any of the Properties, including, without limitation, those that may be in violation or require action under any Environmental Law. As used herein “Environmental Condition” means any pollution, contamination, degradation, damage or injury caused by, related to, arising from, or in connection with the generation, handling, use, treatment, storage, transportation, disposal, discharge, release, or emission of any Hazardous Materials (defined below) or Contaminants (as defined below) on, at or under the Properties.

5.06 Notice of Defective Interests and Environmental Defects

(a) Notice; Thresholds. Buyer shall give the Petro-Hunt Parties notice of Defective Interests and Environmental Defects not later than five (5) business days prior to Closing. Such notice shall be in writing and shall include (i) a description of the Defective Interest or the Environmental Defect, as applicable, (ii) the reason Buyer believes such Properties to be a Defective Interest or affected by an Environmental Defect, and (iii) to the extent known or susceptible to reasonable estimation, the Title Defect Value or Environmental Defect Values asserted by Buyer with respect to the asserted Defective Interest or Environmental Defect, as applicable. Buyer’s notice(s) of Defective Interests shall not be effective unless and until (i) the asserted individual Title Defect Value of any single Defective Interest exceeds $75,000 (and to the extent such threshold is exceeded, the entire Title Defect Value for such Defective Interest shall be recoverable), and (ii) the total of the asserted Title Defect Values for the asserted Defective Interests when combined with the total of the asserted Environmental Defect Values for all asserted Environmental Defects exceeds an aggregate threshold equal to one-half percent (0.5%) of the Purchase Price (and if such aggregate 0.5% threshold is exceeded, the entire Title Defect Value for such Defective Interests shall be recoverable). Buyer’s notice(s) of Environmental Defects shall not be effective unless and until (x) the asserted Environmental Defect Value of any single Environmental Defect exceeds $75,000 (and to the extent such threshold is exceeded, the entire Environmental Defect Value for such Environmental Defect shall be recoverable) and (y) the total of the asserted Environmental Defect Values for all of the asserted Environmental Defects when combined with the total of all of the asserted Title Defect Values for all asserted Defective Interests exceeds an aggregate threshold equal to one-half percent (0.5%) of the Purchase Price (and if such 0.5% threshold is exceeded, the entire Title Defect Value for such Defective Interests shall be recoverable). Buyer shall be deemed to have waived all Defective Interests of which the Petro-Hunt Parties has not been given such notice within the time period prescribed in this Section 5.06(a). Except for claims that Buyer would have for breach of the representations and warranties in Section 3.01(q) and except with regard to any of the Petro-Hunt Party Obligations (as hereinafter defined), Buyer shall be deemed to have waived all Environmental Defects of which the Petro-Hunt Parties have not been given such notice within the time period prescribed in this Section 5.06(a).

(b) Right to Counter-Notice. Upon being notified by Buyer pursuant to Section 5.06(a) of any asserted Defective Interest or Environmental Defect, the Petro-Hunt Parties shall give written counter-notice to Buyer within three (3) business days (i) that the Petro-Hunt Parties either (A) will attempt to correct the asserted Defective Interest or remediate the asserted Environmental Defect or (B) do not intend to attempt to correct the asserted Defective Interest or remediate the asserted Environmental Defect; (ii) whether the Petro-Hunt Parties agree or disagree that the asserted Defective Interest or Environmental Defect exists, and (iii) whether the Petro-Hunt Parties agree or disagree with the Title Defect Value or Environmental Defect Value asserted by the Buyer. If the Petro-Hunt Parties notify Buyer that it does not intend to attempt to correct the asserted

Defective Interest or remediate the asserted Environmental Defect, then (x) Buyer may elect to reduce the Purchase Price by the Title Defect Value or the Environmental Defect Value asserted by Buyer, or (y) if Buyer does not elect (x) above, then solely as to Properties affected by Environmental Defects, Buyer or the Petro-Hunt Parties may elect to exclude any affected Properties from the properties and assets to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeds as a result of the Mergers. If the affected Properties are to be excluded, the Purchase Price at Closing will be reduced by the Allocated Value for such Properties and such Properties shall thereafter be considered Excluded Assets. If the Petro-Hunt Parties fails to give a counter-notice hereunder prior to Closing, the Petro-Hunt Parties will be deemed to have waived any right to dispute or disagree with the Defective Interest or Environmental Defect noticed under this Section 5.06(b), and (x) Buyer may elect to reduce the Purchase Price by the Title Defect Value or the Environmental Defect Value asserted by Buyer or (y) if Buyer does not elect (x) above, then solely as to Properties affected by Environmental Defects, Buyer or the Petro-Hunt Parties may elect to exclude any affected Properties from the properties and assets to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeds as a result of the Mergers.

(c) Cure Period. If the Petro-Hunt Parties give counter-notice of intent to attempt to correct any asserted Defective Interest or remediate any asserted Environmental Defect, under 5.06(b) above, and assuming this Agreement is not otherwise terminated in accordance with the terms hereof, the Petro-Hunt Parties shall have a period of 150 days from the receipt of Buyer’s notice (the “Cure Period”) to attempt to correct such asserted Defective Interest or remediate the asserted Environmental Defect at their own expense using the Lowest Cost Response as provided herein. Unless the parties agree otherwise in writing, the Closing shall not be extended, but to the extent and only to the extent that the Title Defect Value allocated to the Defective Interest when combined with the value of all other asserted Defective Interests and Environmental Defects exceeds the aggregate threshold of one-half percent (0.5%) of the Purchase Price (and if the aggregate threshold is met, the entire Title Defect Value for such Defective Interest shall be recoverable), a downward adjustment of the Purchase Price shall be made according to Section 2.02(b)(3), taking into account applicable thresholds. Within the Cure Period, if the Petro-Hunt Parties subsequently cures any asserted Defective Interest or remediates an Environmental Defect, the cured Title Defect Value or Environmental Defect Value will either be credited to the Petro-Hunt Parties in the Final Settlement according to Section 8.01 hereof; or, if an affected Property was excluded from the properties and assets to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeds as a result of the Mergers, then subject to the other terms and conditions of this Agreement the affected Property shall be deemed to be included in the properties and assets to which Petro-Hunt FB/M Successor and Pillar FB/M Successor succeed as a result of the Mergers as of the effective date of the Mergers at a supplemental closing held within ten (10) days following the end of the Cure Period (and to the extent requested by Buyer, the parties shall execute such amendments to the articles of merger or execute and deliver such conveyances as may be necessary to accomplish such result).

(d) Dispute on Existence of Defect. If the Petro-Hunt Parties give counter-notice according to Section 5.06(b) and dispute a Defective Interest or Environmental Defect, then its existence, Title Defect Value, or Environmental Defect Value will be determined by arbitration pursuant to Section 5.07 hereof.

(e) Applicable Portions of Properties. To the extent possible, the parties will only include that portion of the Properties actually affected by the Defective Interests or Environmental Defect in determining how to treat the Properties under this Agreement.

5.07 Arbitration Procedures. If any matter is required by this Article to be arbitrated, such arbitration shall be conducted as set forth in this Section 5.07.

(a) The parties shall jointly select an acceptable, independent person to serve as the sole arbitrator under this Agreement. The arbitrator for any Title Defects submitted for arbitration shall be an oil and gas title attorney licensed in the State of North Dakota and Board Certified by the State Bar of North Dakota in the area of Oil, Gas & Energy Resource Law with at least ten (10) years’ experience with oil and gas title review regarding properties in North Dakota. The arbitrator for any Environmental Defect submitted for arbitration shall be a licensed environmental attorney with at least ten (10) years’ experience, and specific experience regarding environmental issues associated with oil and gas properties. If the parties are unable to agree upon the designation of a person as arbitrator under this Section 5.07, then either the Petro-Hunt Parties or Buyer, or both such parties, may in writing request the American Arbitration Association to appoint a qualified, independent arbitrator, based on the criteria described above.

(b) Any arbitration hearing shall be held at a place acceptable to the arbitrator in Dallas, Texas.

(c) The arbitrator shall settle disputes regarding the existence of Defective Interests and/or the Title Defect Value thereof and of Environmental Defects and/or the Environmental Defect Value thereof and the Petro-Hunt Parties’ attempts to correct any Title Defects or remediate any Environmental Defects in accordance with the then in force Commercial Arbitration Rules of the American Arbitration Association (“AAA Rules”). Such arbitrator shall hear all arbitration matters arising under this Article V. The decision of the arbitrator shall be binding upon the parties, and may be enforced in any court of competent jurisdiction. The Petro-Hunt Parties and Buyer, respectively, shall bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the arbitrator shall be shared equally by the Petro-Hunt Parties and Buyer.

(d) The arbitration shall commence within ten days after the arbitrator is selected as set forth in Section 5.07(a) above. In fulfilling his duties hereunder, the arbitrator shall be bound by the terms of this Agreement. In fulfilling any of his arbitration duties, the arbitrator may consider such other matters as in the opinion of the arbitrator are necessary or helpful to make a proper evaluation. Additionally, the arbitrator may consult with and engage disinterested third parties, including, without limitation, petroleum engineers, attorneys and consultants, to advise the arbitrator.

(e) If any arbitrator selected hereunder should die, resign or be unable to perform his duties hereunder, the parties, or if the parties are unable to agree, the American Arbitration Association shall select a replacement arbitrator. The aforesaid procedure shall be followed from time to time as necessary.

5.08 Effect of Disputed Defective Interests or Environmental Defects on Closing. If Buyer asserts any Defective Interests or Environmental Defects that are disputed and referred to arbitration under Section 5.07 hereof, the following shall apply:

(a) If any matter is referred to arbitration under Section 5.07 of this Agreement and the Title Defect Value or Environmental Defect Value asserted by Buyer with respect to the matters under arbitration when combined with all other adjustments described above with regard to asserted Defective Interests and asserted Environmental Defects (together with the values and the adjustments associated with casualty losses, un-obtained consents, exercised preferential purchase rights, disputed Defective Interests or Environmental Defects, or removed and excluded Properties, or other adjustments) totals less than $217,500,000, then, subject to the satisfaction of the other terms and conditions of this Agreement, the parties shall proceed to Closing, and the Properties affected by the asserted Defective Interests and Environmental Defects shall be included within the properties and assets to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeds as a result of the Mergers, and the Closing Amount (defined below) shall be reduced by the aggregate amount equal to the asserted Title Defect Values of the asserted Defective Interests and asserted Environmental Defect Values of the asserted Environmental Defects. If the arbitrator decides that any Defective Interest or Environmental Defect asserted by the Buyer is not a Defective Interest or Environmental Defect, then the applicable Title Defect Value or Environmental Defect Value withheld from the Closing Amount for Properties conveyed to Buyer at Closing shall be paid to New DE PH and Pillar Holdings within thirty (30) days after such determination. If the arbitrator decides that any one or more of the Defective Interests or Environmental Defects asserted by the Buyer are in fact Defective Interests or Environmental Defects, and if the Title Defect Value and the Environmental Defect Value of such Defective Interests or Environmental Defects as determined by the arbitrator, when combined with all other Defective Interests and Environmental Defects exceeds one-half percent (0.5%) of the Purchase Price, then Buyer shall retain the applicable Title Defect Value or Environmental Defect Value withheld from the Closing Amount with respect to the applicable Properties.

(b) If any matter is referred to arbitration under Section 5.07 of this Agreement and the Title Defect Value or Environmental Defect Value asserted by Buyer with respect to the matters under arbitration when combined with all other adjustments to the Purchase Price relating to Defective Interests and Environmental Defects (as well as casualty losses, un-obtained consents, exercised preferential purchase rights, disputed Defective Interests or Environmental Defects, or removed and excluded Properties, or other adjustments) totals $217,500,000 or more, and this Agreement is not terminated by the Petro-Hunt Parties or Buyer pursuant to Article IX hereof, then the Closing shall not be postponed and the parties shall close and consummate the transactions at the closing and only the Properties as to which there is no such dispute related to Defective Interests and Environmental Defects will be included as assets to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeds as a result of the Mergers (and the Purchase Price shall be reduced by the Allocated Values for such excluded Properties). If the arbitrator decides that any Defective Interest or Environmental Defect asserted by the Buyer is not a Defective Interest or Environmental Defect, then the parties shall have a supplemental within thirty (30) days of such determination, at which time, such applicable Properties will be deemed to have been included in the Properties to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeded as a result of the Mergers as of the effective time of the Mergers in accordance with the terms and provisions of this Agreement (and to the extent requested by Buyer, the parties shall execute such amendments to the articles of merger or execute and deliver such conveyances as may be necessary to accomplish such result), and Buyer shall pay the Allocated Value attributable to such applicable Properties, subject to the adjustments provided for in this Agreement relative thereto. If the arbitrator decides that any one or more of the Defective Interests or Environmental Defects asserted by the Buyer are in fact Defective Interests or Environmental Defects, and if the Title Defect Value and the Environmental Defect Value of such Defective Interests or Environmental Defects as determined by the arbitrator, when combined with all other Defective Interests and Environmental Defects exceed one-half percent (0.5%) of the Purchase Price, then, at Buyer’s election, the affected Properties shall either be deemed to be Excluded Assets or the parties shall schedule a supplemental Closing within thirty (30) days after such determination, at which time, subject to the other terms and conditions of this Agreement, such Properties will be deemed to have been included in the Properties to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeded as a result of the Mergers as of the effective time of the Mergers (and to the extent requested by Buyer, the parties shall execute such amendments to the articles of merger or execute and deliver such conveyances as may be necessary to accomplish such result) and Buyer shall pay to the Petro-Hunt Parties the Allocated Value, less the asserted Title Defect Value or Environmental Defect Value, as applicable, and subject to the other adjustments

contemplated in this Agreement related thereto (and to the extent requested by Buyer, the parties shall execute such amendments to the articles of merger or execute and deliver such conveyances as may be necessary to accomplish such result).

5.09 Preferential Purchase Rights. Within five (5) business days following the execution and delivery of this Agreement, the Petro-Hunt Parties will provide written notice in form and substance satisfactory to Buyer to any persons under the Lease, Contract or agreement requiring a preferential purchase, right of first refusal, or similar option (a “Preferential Right”). Upon receipt of notice hereunder, the Petro-Hunt Parties will notify Buyer within five (5) business days of (a) any Preferential Rights exercised, waived or deemed waived, or (b) lapse of the requisite time periods without exercise of such Preferential Rights. Subject to the conditions in Section 6.02(d) and the right to terminate this Agreement under Section 9.01(c) hereof), if a Preferential Right is duly exercised prior to Closing, the affected Properties shall be deemed Excluded Assets, and the Purchase Price shall be reduced by the Allocated Value thereof. However, five (5) days prior to the Closing Date, if a Preferential Right has not been waived or exercised, and the requisite exercise period for such Preferential Right have not elapsed, then the Petro-Hunt Parties or Buyer may exclude the affected Properties from the assets and properties to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeds as a result of the Mergers, adjust the Purchase Price downward by the Allocated Value of such Properties, and such affected Properties shall be deemed to be Excluded Assets; provided, however, that if the required waiver of Preferential Rights is obtained within ninety (90) days after Closing, the affected Properties will be deemed to have been included in the Properties to which Petro-Hunt FB/M Successor or Pillar FB/M Successor succeeded as a result of the Mergers as of the effective time of the Mergers (and to the extent requested by Buyer, the parties shall execute such amendments to the articles of merger or execute and deliver such conveyances as may be necessary to accomplish such result), and Buyer will pay the Allocated Value thereof to Petro-Hunt Holdings and Pillar Holdings (subject to adjustments provided herein), within ten (10) business days of written notice by the Petro-Hunt Parties to Buyer that such Preferential Rights have been waived (with a copy of the evidence thereof).

5.10 Casualty Losses. Prior to Closing Date, if, all or a material part of any of the Properties are damaged or destroyed by fire, flood, storm or other casualty (“Casualty Loss”), or same are taken in condemnation or by eminent domain, or if proceedings for such purposes are pending or threatened (“Government Taking”), the Petro-Hunt Parties must promptly notify Buyer in writing thereof and their estimated cost to repair or replace that portion of the Properties affected by the Casualty Loss or value of the Properties taken by the Government Taking. If all or any portion of the Properties is affected by Casualty Loss or Government Taking, the Purchase Price will be adjusted downward by the agreed dollar amount of the Casualty Loss or Government Taking. If the parties cannot agree on the appropriate amount, and Buyer does not elect the options described below, then the appropriate amount will be determined pursuant to an arbitration procedure similar to the one described in Section 5.07, and the affected Properties will be excluded from the assets and properties to which Petro-Hunt FB/M

Successor or Pillar FB/M Successor succeeds as a result of the Mergers for purposes of the Closing, and the Purchase Price reduced by the Allocated Value thereof, and the parties will then close, subject to the other terms and conditions of this Agreement. At Buyer’s sole election, in lieu of adjustments to the Purchase Price, Buyer may elect to receive and the Petro-Hunt Parties shall immediately pay over to Buyer when actually received: (i) all insurance proceeds payable to the Petro-Hunt Parties with respect to any Casualty Loss, (ii) all sums paid to the Petro-Hunt Parties by third parties for any such Casualty Loss, (iii) all compensation paid to the Petro-Hunt Parties with respect to any Government Taking. In addition to the remedies set forth hereinabove, the Petro-Hunt Parties and Buyer will have the termination rights in Section 9.01(c) as to Casualty Losses and Government Takings.

5.11 Consents. Within five (5) days following the execution and delivery of this Agreement, the Petro-Hunt Parties will provide written notice in form and substance reasonably satisfactory to Buyer to any persons under any Lease or Contract requiring a right to consent to the conveyance of any Properties hereunder, including, without limitation, those set forth on Schedule 3.01(d). Upon receipt of notice hereunder, the Petro-Hunt Parties will notify Buyer within two (2) business days of (a) any requested consents which are denied, or (b) the lapse of requisite time periods for such consents to be given and received, together with a summary of which required consents, if any, remain outstanding. However, five (5) days prior to the Closing Date, if the requisite time for such consent has not elapsed and the consent is not waived, the Petro-Hunt Parties or Buyer may exclude the affected Properties from the assets and properties to which Petro-Hunt FB/M Successor of Pillar FB/M Successor succeeds as a result of the Mergers, adjust the Purchase Price downward by the Allocated Value of such Properties, and such affected Properties shall be deemed to be Excluded Assets; provided, further, however, that if the required consent is obtained within ninety (90) days after Closing, the affected Properties will be deemed to have been included in the Properties to which Petro-Hunt FB/M Successor of Pillar FB/M Successor succeeded as a result of the Mergers as of the effective time of the Mergers (and to the extent requested by Buyer, the parties shall execute such amendments to the articles of merger or execute and deliver such conveyances as may be necessary to accomplish such result), and Buyer will pay for the Allocated Value thereof to Petro-Hunt Holdings and Pillar Holdings (subject to other adjustments provided herein), within thirty (30) days of written notice by the Petro-Hunt Parties to Buyer that such consent has been waived (with a copy of the evidence thereof).

5.12 Upward Adjustment. If (a) Petro-Hunt FB/M Successor and Pillar FB/M Successor own more than the net mineral acres set forth on Exhibit “A”, Part I allocable to the Undeveloped Leases (and excluding, for purposes hereof, net mineral acres allocable to the Allocated Unit for a Well) or (b) Petro-Hunt FB/M Successor and Pillar FB/M Successor own a Net Revenue Interest in either the Wells (and the associated Allocated Unit) or the Undeveloped Leases that exceeds the amounts set forth on Exhibit “A”, Part I and Exhibit “C”, respectively for such ell or Undeveloped Lease, then there may be set-off against the Title Defect Value of the Defective Interests, in accordance with the terms hereof (the “Upward Adjustment”), provided, however, that this ability to offset are subject to and limited by the following:

(i) there shall be no Upward Adjustment available for such offset to the extent either: (1) the individual increase available for offset would not exceed $75,000 (and to the extent such threshold is exceeded, or the entire amount will be credited as an Upward Adjustment), or (2) the aggregate value of all such Upward Adjustments, all of which exceed the individual threshold described in subpart (i)(1) above, would not exceed an aggregate threshold equal to 0.5% of the Purchase Price;

(ii) with regard to Upward Adjustments based on additional net mineral acres which are not reflected in Exhibit A, Part I, such additional net mineral acres may only be used to offset deficiencies in net mineral acres attributable to the Undeveloped Leases insofar and only insofar as the additional net mineral acres being used to offset are in the same geographic area and would have the same Per Net Mineral Acre Price as those they are offsetting (and if they are not otherwise in the same geographic area which would be included in the same Per Net Mineral Acre Price, then any ability to use the same to offset or the value thereof shall be based solely on the mutual agreement of the parties on the same);

(iii) with regard to Upward Adjustments relative to increased Net Revenue Interests, the value thereof shall be based on the Allocated Value of the applicable Property and calculated in a manner similar to the calculation of the Title Defect Value, and

(iv) notwithstanding anything stated herein to the contrary, if the aggregate Upward Adjustment (or Acreage Adjustment), or the value thereof, exceeds the aggregate Title Defect Values of all Defective Interests asserted, there shall be no upward adjustment of the Purchase Price, and the same may ONLY be used to offset the Title effect Value of asserted Defective Interests, as described above; and

(v) The Petro-Hunt Parties and Buyer agree that: (1) the net mineral acres reflected on Exhibit A, Part I allocable to the Undeveloped Leases include 1,754 more net mineral acres than have been allocated value for purposes of calculating the Purchase Price (with no upward adjustment to the Purchase Price for the same); and (2) should there be Title Defects discovered that result in a reduction in net mineral acres allocable to the Undeveloped Leases included in the transaction, there shall be no Title Defect Value applied to the aggregate defect threshold of 0.5% of the Purchase Price (as described above), except to the extent that the reduction in net mineral acres exceeds 1,754 net mineral acres (the “Acreage Adjustment”), insofar and only insofar as the net mineral acres attributable to the Acreage Adjustment are in the same geographic area and would have the same Per Net Mineral Acre Price (if such net mineral acres had, in fact,

been valued for purposes of the calculation of the Purchase Price) as those they are offsetting, as described in subpart (ii) above (and if they are not, then the Acreage Adjustment shall not restrict the application of the Title Defect Value for such Defective Interests as otherwise contemplated in this Agreement).

5.13 Exclusive Remedy. THIS ARTICLE V SHALL, TO THE FULLEST EXTENT PERMITTED PURSUANT TO APPLICABLE LAW, BE THE EXCLUSIVE RIGHT AND REMEDY OF THE PARTIES WITH RESPECT TO ANY CLAIM RELATED TO TITLE MATTERS (INCLUDING TITLE DEFECTS OR ANY CLAIM UNDER SECTION 5.01). IN ADDITION, EXCEPT FOR CLAIMS RELATING TO A BREACH OF THE REPRESENTATIONS AND WARRANTIES IN SECTION 3.01(q) AND EXCEPT FOR MATTERS CONSTITUTING PETRO-HUNT PARTY OBLIGATIONS (AS HEREINAFTER DESCRIBED) THIS ARTICLE V SHALL, TO THE FULLEST EXTENT PERMITTED PURSUANT TO APPLICABLE LAW, BE THE EXCLUSIVE RIGHT AND REMEDY OF THE PARTIES WITH RESPECT TO ANY CLAIM RELATED TO ENVIRONMENTAL MATTERS RELATING TO THE PROPERTIES. FROM AND AFTER CLOSING, AND EXCEPT FOR MATTERS THAT ARE BEING DISPUTED OR WHICH REMEDIES UNDER ARTICLE V HAVE NOT BEEN FULLY RESOLVED AND ADDRESSED IN ACCORDANCE WITH THE PROVISIONS HEREOF, BUYER RELEASES, REMISES, AND FOREVER DISCHARGES THE PETRO-HUNT PARTIES AND THEIR AFFILIATES AND ITS AND THEIR RESPECTIVE EMPLOYEES, AGENTS, ADVISORS AND REPRESENTATIVES FROM ANY AND ALL SUITS, LEGAL OR ADMINISTRATIVE PROCEEDINGS, CLAIMS, DEMANDS, DAMAGES, LOSSES, COSTS, LIABILITIES, INTERESTS, OR CAUSES OF ACTION WHATSOEVER, IN LAW OR IN EQUITY, KNOWN OR UNKNOWN, WHICH BUYER MIGHT NOW OR SUBSEQUENTLY MAY HAVE BASED ON, RELATING TO, OR ARISING OUT OF, ANY CLAIM RELATED TO TITLE MATTERS OR ENVIRONMENTAL MATTERS (EXCEPT FOR CLAIMS RELATING TO A BREACH OF THE REPRESENTATIONS AND WARRANTIES IN SECTION 3.01(q) AND EXCEPT FOR MATTERS CONSTITUTING PETRO-HUNT PARTY OBLIGATIONS OF THE PETRO-HUNT PARTIES).

Obligations After Closing

8.01 Post-Closing Adjustments.

(a) As soon as practicable after Closing, but not later than 90 days after the Closing, the Petro-Hunt Parties shall prepare and deliver to Buyer, in accordance with this Agreement, a statement (the “Petro-Hunt Parties’ Final Settlement Statement”) setting forth each adjustment to Purchase Price that was not finally determined as of the Closing and showing the calculation of such adjustments. As soon as practicable after receipt of the Petro-Hunt Parties’ Final Settlement Statement, and no later than 120 days after the Closing Date, Buyer shall deliver to the Petro-Hunt Parties a written report containing any changes that Buyer proposes be made to the Petro-Hunt Parties’ Final Settlement Statement.

If Buyer fails to propose any changes to the Petro-Hunt Parties’ Final Settlement Statement, Buyer shall be deemed to have agreed therewith. The final agreed price paid by Buyer after all adjustments is hereinafter referred to as the “Final Purchase Price.” The date upon which such agreement is reached or upon which the Final Purchase Price is established, shall be herein called the “Final Settlement Date.”

(b) If the Petro-Hunt Parties and Buyer cannot agree on the Final Purchase Price within 150 days from the Closing Date, independent certified public accountants approved by Buyer and the Petro-Hunt Parties will act as arbitrators to decide all points of disagreement with respect to the Final Purchase Price. Such decision will be binding upon all parties. If the parties cannot agree on independent certified public accountants to use, then Buyer shall select one independent, certified public accountant firm, and the Petro-Hunt Parties shall select one independent, certified public accountant firm, and the two selected by the respective parties shall be charged with selecting one independent, certified

public accountant firm to be used for such purposes. If no independent certified public accountants are willing or able to serve under this Section 8.01(b), the Petro-Hunt Parties and Buyer will designate in good faith another acceptable independent certified public accountant as the sole arbitrator under this Section. If the parties are unable to agree upon such substitute arbitrator, then the Petro-Hunt Parties or Buyer, or both of them, may request in writing that the American Arbitration Association appoint a substitute independent certified public accountant arbitrator. The arbitration shall be conducted under the rules of the American Arbitration Association to the extent such rules do not conflict with the terms hereof. The costs and expenses of the arbitrator shall be shared equally by the Petro-Hunt Parties and Buyer. Within five (5) business days after the final decision of the arbitrator or agreement of the parties, the Buyer or the Petro-Hunt Parties, as the case may be, shall promptly pay to the other such amount as is due to arrive at the Final Purchase Price, together with interest on the amount of such payment at the rate of 3% per annum, compounded monthly since the Closing Date. Notwithstanding the provisions of this Section 8.01(b), any questions with respect to a Defective Interest, Title Defect Value, Environmental Defect or Environmental Defect Value shall be resolved pursuant to the terms of Article V hereof.

8.02 Transition Services. Before the Closing, the Petro-Hunt Parties and Buyer agree to negotiate in good faith a form of Transition Services Agreement (the “TSA”), whereby the Petro-Hunt Parties will agree to provide certain transition services to Buyer related to the operation and management of the Properties. The TSA shall provide and describe which services that the Petro-Hunt Parties will provide to Buyer, what time frame, and adequate compensation to the Petro-Hunt Parties from Buyer with regard thereto.

Some equipment and sites included in the Properties may contain naturally occurring radioactive material (“NORM”), asbestos, or other Hazardous Materials. NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms; the wells, materials, and equipment located on the Properties or included in the Properties may contain NORM, asbestos, or other Hazardous Materials; and NORM-containing material and other Hazardous Materials may have been buried or otherwise been disposed of on the Properties. Special procedures may be required for the remediation, removal, transportation, or disposal of NORM or other Hazardous Materials from the Properties.

Nothing contained in this Section 8.04(b) shall limit any remedies the parties may otherwise have pursuant to Article V of this Agreement or under this Article VIII.

(c) FB/M Obligations and Petro-Hunt Party Obligations.

Failure of the indemnified party to notify the indemnifying party of such claim, action, or suit within twenty (20) calendar days after notice to the indemnified party of such claim, action, or suit shall constitute a waiver of its rights under this Article, unless such failure to notify within such time period will not prejudice the rights of the indemnifying party in respect of such claim, action or suit, in which case prompt notification as provided above shall be sufficient.

(b) The indemnified party shall have the right to employ counsel separate from counsel employed by the indemnifying party in any such action and to participate in the defense thereof, but the fees and expenses of such counsel employed by the indemnified party shall be at the sole expense of the indemnified party unless (i) the indemnifying party shall have elected not or shall have failed to assume or participate in the defense thereof, (ii) the employment of such counsel has been specifically authorized by the indemnifying party in writing, or (iii) the parties to any such action (including any impleaded parties) include both the indemnifying and indemnified party, and the indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, and the indemnifying party or its counsel would be prohibited from asserting such defenses under applicable ethical or procedural rules. In any of (i), (ii), or (iii) above, the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party and the fees and expenses of such counsel employed by the indemnified party shall be at the sole expense of the indemnifying party).

(c) Prior to effectuating any settlement of any action or proceeding under this Section 10.01, the indemnified party shall furnish the indemnifying party with written notice of any proposed settlement in sufficient time to allow the indemnifying party to act thereon.
