4. Representations and Warranties of Seller. Seller represents and warrants to Buyer as of the date hereof, as follows:

To Seller’s best knowledge, there is no condition or discharge of hazardous materials on or attributable to the Subject Property that requires (or will require solely with the passage of time) remediation under Environmental Laws. No notice or action alleging such violation is pending or, to Seller’s knowledge, threatened against the Subject Property.

(l) Obligation to Close. Seller shall take or cause to be taken all actions necessary or advisable to consummate the transactions contemplated by this Agreement and to assure that as of the Closing it will not be under any material, corporate, legal, governmental or contractual restriction that would prohibit or delay the timely consummation of such transactions.

(m) No Third Party Options. There are no existing agreements, options, or commitments with, of or to any person to acquire the Subject Property.

(n) Existing Condition.

There have been no material adverse changes in the condition of the Subject Property from the Effective Date to the Closing Date.

(o) Condemnation. To Seller’s knowledge, there is no actual or threatened taking (whether permanent, temporary, whole or partial) of any part of the Subject Property by reason of condemnation or the threat of condemnation.

(p) Bankruptcy. There are no bankruptcy, reorganization, or similar arrangement proceedings pending, being contemplated by or, to Seller’s knowledge, threatened against Seller.

(q) Governmental Authorizations. Except as disclosed on Schedule 4(q), Seller, and to Seller’s knowledge any Third Party Operator, has obtained and is maintaining all federal, state and local governmental licenses, permits, franchises, orders, exemptions, variances, waivers, authorizations, certificates, consents, rights, privileges and applications therefor (the “Governmental Authorizations”) that are presently

necessary or required for the operation of the Subject Property operated by such person as currently operated. Except as disclosed in Schedule 4(q), (i) Seller, and to Seller’s knowledge any Third Party Operator, has operated the Subject Property operated by it in accordance with the conditions and provisions of such Governmental Authorizations, and (ii) no notices of violation have been received by Seller, and no proceedings are pending or, to Seller’s knowledge, threatened in writing that might result in any modification, revocation, termination or suspension of any such Governmental Authorizations or which would require any corrective or remediation action by Seller. For purposes hereof, “Third Party Operator” means any third party that operates any of the Subject Property.

(r) Consents and Preference Rights. Except as set forth on Schedule 4(r), none of the Subject Property, or any portion thereof, is subject to any (i) third party preferential rights to purchase or similar third party rights, or (ii) restrictions on assignment or required third-party consents to assignment, except for governmental consents and approvals of assignments that are customarily obtained after Closing.

(s) Contracts. Other than the Leases, Units and Fee Interests and the chain of title documents thereto that are recorded in the public records in the chain of title to the Subject Properties, Exhibit “C” lists all of the contracts and agreements to which the Subject Properties are bound or to which Buyer or any of the Subject Properties will be bound as of the Closing. Seller is not and, to Seller’s knowledge, no other party is, in material default under any Contract except as disclosed on Exhibit “C”.

(t) Capital Commitments. As of the date of this Agreement, there is no individual outstanding authority for expenditure which is binding on the Subject Property the value of which Seller reasonably anticipates exceeds Twenty-Five Thousand dollars ($25,000) to Seller’s interests participating in the operation covered by such authority for expenditure, other than those shown on Schedule 4(t) hereto.

(u) Non-Consent. Except as set forth on Schedule 4(u), Seller has not elected not to participate in any operation or activity proposed with respect to the Subject Property which could result in any of Seller’s interest in such Subject Property becoming subject to a penalty or forfeiture as a result of such election not to participate in such operation or activity. Schedule 4(u) contains a complete and accurate list of the status of any payout balances for each Subject Property which is subject to a reversion or other adjustment at any level of cost recovery or hydrocarbon production from or attributable to such Subject Property, as of the dates shown on such schedule with respect to each Subject Property.

(v) Xxxxxx. There are no futures, options, swaps, or other derivatives with respect to the sale of hydrocarbons from the Subject Property that are currently binding on the Subject Property or will be binding on the Subject Property after Closing.

5. Representations and Warranties of Buyer. Except for the necessity of, and subject to obtaining the approval of the board of directors of Buyer (provided, if and when such approval has been obtained this exception shall no longer be applicable), Buyer represents and warrants to Seller as of the date hereof, as follows:

(a) Corporate Authority. Buyer is a limited liability company duly organized and in good standing under the laws of the State of Delaware, is duly qualified and in good standing to carry on its business in the state where the Subject Property is located, and has all the requisite power and authority to enter into and perform this Agreement and carry out the transactions contemplated under this Agreement.

(b) Valid Agreement. This Agreement constitutes the legal, valid and binding Agreement of Buyer. At the Closing, all instruments required hereunder to be executed and delivered by Buyer shall be duly executed and delivered by Buyer and shall constitute legal, valid and binding obligations of Buyer. Buyer shall convey to the Xxxxxx Transferees the Xxxxxx Interests, effective as of the Effective Date, without any representation or warranty except a special warranty of title. The execution and delivery by Buyer of this Agreement, the consummation of the transactions set forth herein and the performance by Buyer of Buyer’s obligations hereunder have been duly and validly authorized by all requisite corporate action on the part of Buyer and will not conflict with or result in any violation of any provision of (i) any agreement, contract, mortgage, lease, license or other instrument to which Buyer is a party or by which Buyer is bound; (ii) any governmental franchise, license, permit or authorization or any judgment or order of judicial or governmental body applicable to Buyer, or (iii) any law, statute, decree, rule or regulation of any jurisdiction in the United States to which Buyer is subject.

(c) Independent Evaluation. Buyer is an experienced and knowledgeable investor in the oil and gas business. Except for the representations, warranties and indemnities provided by Seller under this Agreement, Buyer has been advised by and has relied solely on its own expertise and legal, tax, reservoir engineering, environmental and other professional counsel concerning this transaction, the Subject Property and value thereof.

(d) Physical and Environmental Matters. As of Closing, Buyer acknowledges that it has been provided the opportunity to conduct certain independent visual inspections of the Subject Properties, as well as an inspection of the public records and Seller’s files that were provided or made available to Buyer for the purpose of detecting the presence of any environmentally hazardous substance or contamination, including petroleum, and the presence and concentration of naturally-occurring radioactive materials. As a result of such inspection (or opportunity to conduct same) and the representations, warranties and indemnities provided by Seller under this Agreement, Buyer will have satisfied itself as of Closing as to the physical condition and environmental condition of the property, both surface and subsurface. Buyer acknowledges that, except as set forth in this Agreement, no representations have been made by Seller regarding environmental conditions or physical conditions, past or present.

(e) Brokers. Buyer has incurred no obligation or liability, contingent or otherwise for brokers’ or finders’ fees with respect to this transaction for which Seller shall have any obligation or liability.

6. Title Matters.

(a) Examination of Files and Records. Upon execution of and pursuant to the terms of this Agreement, Buyer shall have the right to conduct its investigation of the status of title to the Subject Properties. Seller will make available to Buyer its existing Lease, Well, Unit and title files, production records, Easements, Contracts, division orders and other information, to the extent not subject to confidentiality agreements (provided Seller could not reasonably be granted access through an exception under such confidentiality agreements), available in Seller’s files relating to the Subject Property (collectively “Data”). Existing abstracts and title opinions will not be updated by Seller. Upon reasonable advanced notice from Buyer, all such Data shall be made available at Seller’s office during normal working hours. Seller will also permit Buyer to examine and copy at Buyer’s expense such Data. If Closing does not occur, Buyer shall promptly return all such Data and other materials provided by Seller to Buyer hereunder.

(b) Notice of Title Defect. Buyer will review title to the Subject Property prior to Closing and notify Seller in writing of any Title Defect (defined below) it discovers as soon as reasonably practicable after its discovery, but in no event less than three (3) business days prior to the Closing Date. Any notice provided hereunder shall include appropriate evidence to substantiate Buyer’s position, including a description of the Title Defect, the basis for the Title Defect, the portion of the Lease or other part of the Subject Property affected by the Title Defect, the Title Defect Amount (as defined below) by which Buyer believes the value of the Subject Property has been reduced because of the Title Defect and the computations and information upon which Buyer’s belief is based. Buyer will be deemed to have conclusively waived any Title Defect about which it fails to notify Seller in writing within the applicable period specified in the preceding sentence except as otherwise provided herein and except for the special warranty of title provided in the Assignment.

(c) Procedure. If Buyer properly notifies Seller of a Title Defect, Buyer and Seller shall promptly meet and, in good faith, negotiate in an effort to agree upon the validity of each claimed Title Defect and the resolution of such claimed Title Defects. Absent an agreement on the claimed Title Defect before Closing, Buyer shall have the option to either (i) waive the Title Defect and proceed to Closing, or (ii) request that Seller cure the Title Defect, but Seller shall have no obligation to cure any Title Defect. If Seller elects not to cure a Title Defect, Seller shall, at its sole option before Closing, either (i) reduce the Purchase Price to account for such Title Defect by the Title Defect Amount (as mutually agreed or estimated by Buyer pursuant to Section 6(h)), but not to exceed the Allocated Value (as defined below) of the affected Subject Property and convey such affected Subject Property to Buyer at Closing or (ii) retain title to the affected Subject Property and decrease the Purchase Price by an amount equal to the Allocated Value of the affected Subject Property. If Seller elects before Closing to attempt to cure the Title Defect, Seller will have ninety (90) days following the Closing Date to attempt to cure the Title Defect. With respect to a Title Defect that Seller is unable to cure or refuses to cure within such ninety (90) day period following the Closing Date, Buyer shall elect, at its sole option, (i) to have a downward adjustment to the Purchase Price to account for such Title Defect equal to the Title Defect Amount, but not

to exceed the Allocated Value of the affected Subject Property and retain title to the affected Subject Property assigned at Closing, or (ii) to have Seller refund to Buyer the Allocated Value of the affected Subject Property (net of any Title Defect Amount withheld at Closing) and to immediately reassign the affected Subject Property to Seller if such property was previously conveyed to Buyer.

(d) Definition of Title Defect. For purposes of this Agreement, the term “Title Defect” shall mean any single matter in excess of Twenty Five Thousand dollars ($25,000.00), positive or negative, that would cause the title to the Subject Property to fail to qualify as Good and Defensible Title (defined below) or which would otherwise reduce the net revenue interest (and/or royalty or overriding royalty interest of Sellers) or for undeveloped interests, the net leasehold or mineral acres, to be conveyed to Buyer as set forth in Exhibit “B”. As used herein, the term “Good and Defensible Title” shall mean, as to each of the Subject Properties, title to the Subject Properties by virtue of which Seller can successfully defend against a claim to the contrary made by a third party, based upon industry standards in the acquisition of oil and gas properties, and in the exercise of reasonable judgment and in good faith, such that (i) Seller (and upon Closing, Buyer), by virtue of its ownership interests in the Leases or Lands described in Exhibit “A”, or Exhibit “A-1” is entitled to receive a fractional decimal interest of not less than the net revenue interest (or “NRI”) (and/or royalty (“RI”) or overriding royalty interest(“ORRI”)) set forth in Exhibit “B”, for the Subject Properties without reduction, suspension, or termination throughout the productive life of each such Subject Property (the “Net Revenue Interest); (ii) Seller is obligated to bear (and after Closing shall obligate Buyer to bear) a fractional decimal interest of not more than the working interest or (“WI”) set forth on Exhibit “B” of the costs and expenses related to the maintenance, development, drilling, equipping, testing, completing, sidetracking, reworking and operation of each Subject Property which are set forth on Exhibit “B” without increase throughout the productive life of each Subject Property (the “Working Interest”); (iii) with respect to the Lands set forth in Exhibit “B-1”, the Subject Properties do not cover less than the net leasehold or mineral acres set forth for such lands on Exhibit “B-1”, and (iv) the Subject Properties are subject to no liens, encumbrances, obligations or defects except those which are Permitted Encumbrances. With respect to the lands set forth on Exhibit “B-1”, the Working Interests and Net Revenue Interests of Seller for purposes of Good and Defensible Title to such lands are the Working Interest or Net Revenue Interest set forth on Exhibit “B-1”. For purposes of this Agreement all references to Exhibit “B” shall be deemed to include a reference to Exhibit “B-1”.

As used herein, the term “Permitted Encumbrances” shall mean:

(1) Lessors’ royalties, overriding royalties, payments out of production, reversionary interests and other burdens affecting Seller’s Net Revenue Interest if the net cumulative effect of such burdens does not operate to (i) reduce the Net Revenue Interest or net acres of Seller in any Subject Property to less than the Net Revenue Interest or net acres for such Subject Property as set forth in Exhibit “B”; or (ii) increase the Working Interest of Seller in any such Subject Property to greater than the Working Interest therefor as set forth in Exhibit “B” (unless Seller’s Net Revenue Interest therein is increased in the same proportion);

(2) Preferential rights to purchase and required third party consents to assignments and similar agreements with respect to which (i) waivers or consents are obtained from the appropriate parties prior to Closing; or (ii) the appropriate time period for asserting such rights has expired without an exercise of such rights;

(3) All rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with the sale or conveyance of oil and gas leases or interests therein if the same are customarily obtained subsequent to such sale or conveyance;

(4) Non-consent penalties applied against the interest of Seller arising under applicable operating agreements scheduled on Exhibit “C” (including non-consent balances) and taken into account in the calculation of the interests shown on Exhibit “B”;

(5) Easements, rights-of-way, servitudes, permits, surface leases and other rights in respect of surface operations which do not interfere with or detract from the operations, value or use of the Subject Properties by Buyer;

(6) Such Title Defects as Buyer has waived or released or is deemed to have waived pursuant to the terms of this Agreement;

(7) The terms and conditions of all Leases and Contracts to the extent listed on Exhibit “A” or Exhibit “C”, provided the same do not result in a decrease in the Net Revenue Interest or net acres or an increase of the Working Interest in any of the Properties (unless Seller’s Net Revenue Interest therein is increased in the same proportion) as set forth on Exhibit “B” and that do not interfere with or detract from the operations, value or use of the Subject Properties by Buyer;

(8) Rights of reassignment, to the extent any exist as of the date of this Agreement, upon the surrender or expiration of any lease;

(9) Liens for taxes or assessments not yet due or not yet delinquent; and

(10) Liens, if any, released at Closing in a form acceptable to Buyer.

(e) Definition of Allocated Value. The term “Allocated Value” shall be the value agreed upon by the Parties for the Subject Property as set forth in Exhibit “B”.

(f) Definition of Title Defect Amount. The “Title Defect Amount” resulting from a Title Defect shall be determined as follows:

(i) if Buyer and Seller agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(ii) if the Title Defect is a lien, encumbrance or other charge which is undisputed and liquidated in amount, then the Title Defect Amount shall be the

amount necessary to be paid to remove the Title Defect from the Subject Property affected by the Title Defect;

(iii) if the Title Defect represents a discrepancy between (A) the Net Revenue Interest for any Subject Property and (B) the Net Revenue Interest stated on Exhibit “B”, or a discrepancy between (A) the net leasehold or mineral acres for any Subject Property and (B) the net leasehold or mineral acres stated on Exhibit “B” then the Title Defect Amount shall be the product of the Allocated Value of such Subject Property affected by the Title Defect multiplied by a fraction, the numerator of which is the Net Revenue Interest (or net acres) decrease and the denominator of which is the Net Revenue Interest (or net acres) stated on Exhibit “B” (as applicable); and

(iv) if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to a Subject Property of a type not described above, then the Title Defect Amount shall be determined by taking into account the Allocated Value of the affected Subject Property, the portion of the Subject Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the affected Subject Property, the values placed upon the Title Defect by Buyer and Seller and such other factors as are necessary to make a proper evaluation, but shall not exceed the Allocated Value of the affected Subject Property.

(g) Increase in Net Revenue Interest/Decrease in Working Interest. Should Buyer and Seller determine after the execution hereof and on or prior to the date that is three business days before Closing that Seller’s Net Revenue Interest or net leasehold or mineral acres in a Subject Property is greater than as shown on Exhibit “B” or that Seller’s Working Interest in a Subject Property is less (without a corresponding decrease in Net Revenue Interest) than as shown on Exhibit “A” or Exhibit “B” and such change exceeds the threshold amount in Section 6(d) (a “Title Benefit”), Buyer and Seller agree to adjust the Purchase Price upward to reflect such change(s) in interest (such upward adjustment being equal to the product of the net increase in Net Revenue Interest (or net acres) or net decrease in Working Interest multiplied by the Allocated Value of the affected Subject Property) and Seller shall correct such Exhibit “A” or Exhibit “B” and convey such interests to Buyer, provided that the aggregate amount of any and all upward adjustments to the Purchase Price on account of a Title Benefit with respect to the Subject Properties shall not exceed the aggregate Title Defect Amounts for the Subject Properties by an amount greater than two percent (2%) of the Purchase Price. Any disagreement between Buyer and Seller as to an adjustment to the Purchase Price made under this Section 6(g) shall be resolved by the Title Arbitrator (as defined below) in accordance with Section 6(h); provided that for purposes of Closing, Buyer’s good faith estimate of the amount of the adjustment shall be used for purposes of the Closing Settlement Statement (as defined below) under Section 10(a).

(h) Title Arbitration. If Seller and Buyer are unable to agree before Closing on the existence or extent of a claimed Title Defect or the Title Defect Amount of a Title Defect, or on whether a Title Defect was properly claimed under Section 6(b), then,

subject to Seller’s right before Closing to elect to retain a Subject Property affected by a Title Defect under Section 6(c), Buyer’s good faith estimate of each Title Defect and Title Defect Amount shall be used for purposes of calculating the downward adjustments to the Purchase Price made in the Closing Settlement Statement under Section 10(a), and the Title Defects and Title Defect Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 6(h). Likewise, if Seller has provided notice prior to the Closing Date of Seller’s intent to attempt to cure a Title Defect and by the end of the applicable cure period, Seller and Buyer have been unable to agree upon whether such Title Defect has been cured, or Seller has failed to cure any Title Defects which it provided notice that it would attempt to cure and Seller and Buyer have been unable to agree on the Title Defect Amounts for such Title Defects, then the cure and/or Title Defect Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 6(h). There shall be a single arbitrator, who shall be a title attorney with at least ten (10) years’ experience in oil and gas titles in the State of Montana as selected by mutual agreement of Buyer and Seller within fifteen (15) days after the end of the cure period described in Section 6(c) (or such other time as mutually agreed). Absent such agreement on the selection of the arbitrator, the arbitrator shall be selected by the Denver, Colorado office of the American Arbitration Association (the “Title Arbitrator”). The arbitration proceeding shall be held in Denver, Colorado and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Title Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the terms set forth in this Section 6(h) and Sections 6(b), 6(c), 6(d), 6(e), 6(f) and 6(g) and may consider such other matters as in the opinion of the Title Arbitrator are necessary or helpful to make a proper determination. Additionally, the Title Arbitrator may consult with and engage disinterested third parties to advise the arbitrator, including without limitation petroleum engineers. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defects and Title Defect Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each Party shall bear one-half of the costs and expenses of the Title Arbitrator.

7. Environmental Matters.

(a) Inspection. Prior to Closing and upon reasonable prior notice to Seller, Buyer will have access to and the opportunity to inspect the Subject Property for all purposes, including without limitation, for the purposes of detecting the presence of hazardous or toxic substances, pollutants or other contaminants, environmental hazards, naturally occurring radioactive materials (NORM), produced water, air emissions, contamination of the surface and subsurface and any other Environmental Defect (defined below). Prior to the Closing and subject to the provisions of this Section, Buyer will have satisfied itself as to the physical and environmental surface and subsurface condition of the Subject Property and method of operation and, except as set forth herein, in the Assignment and in Seller’s representations, warranties or indemnities, to accept an

assignment of the Subject Property at Closing on an “AS IS, WHERE IS” basis, “WITH ALL FAULTS”.

(b) Notice of Environmental Defect. Buyer will notify Seller in writing of any Environmental Defect (defined below) it discovers as soon as reasonably practicable after its discovery, but in no event less than three (3) business days prior to the Closing Date. Any notice provided hereunder shall include appropriate evidence to substantiate Buyer’s position, including a description of the Environmental Defect, the Environmental Law applicable to the Environmental Defect and Buyer’s basis for believing that Seller is in violation of such Environmental Law, the portion of the Lease or other part of the Subject Property affected by the Environmental Defect, the amount by which Buyer believes the value of the Subject Property has been reduced because of the Environmental Defect and the evidence, computations and information upon which Buyer’s belief is based. Buyer will be deemed to have conclusively waived any Environmental Defect of which it has actual knowledge on or before three (3) business days before Closing and about which it fails to notify Seller in writing within the applicable period specified in this paragraph, provided that such waiver shall not affect and Buyer shall not be deemed to have waived (i) Buyer’s rights with respect to Seller’s representations and warranties and its right to indemnification under Section 15(a), or (ii) the right to assert Environmental Defects or claim indemnity for any Environmental Defect Amounts relating to or attributable to any salt water disposal systems located on or used in connection with the Lands or any condition resulting from or caused by such systems or any leaks from such systems that are attributable to the period of time prior to the Closing Date.

(c) Procedure. If Buyer properly notifies Seller of an Environmental Defect, Buyer shall have the option to either (i) waive the Environmental Defect and proceed to Closing, or (ii) request that Seller cure the Environmental Defect, but Seller shall have no obligation to cure any Environmental Defect. If Seller elects not to cure an Environmental Defect, Seller shall, at its sole option before Closing, either (i) reduce the Purchase Price to account for such Environmental Defect by the Environmental Defect Amount (as mutually agreed or estimated by Buyer pursuant to Section 7(f)) and convey such affected Subject Property to Buyer or (ii) retain title to the affected Subject Property and decrease the Purchase Price by an amount equal to the Allocated Value of the affected Subject Property. If Seller elects before Closing to attempt to cure the Environmental Defect, Seller will have ninety (90) days following the Closing Date to attempt to cure the Environmental Defect. With respect to an Environmental Defect that Seller is unable to cure or refuses to cure within such ninety (90) day period following the Closing Date, Buyer shall elect, at its sole option, (i) to have a downward adjustment to the Purchase Price to account for such Environmental Defect equal to the Environmental Defect Amount and retain title to the affected Subject Property assigned at Closing, or (ii) to have Seller refund to Buyer the Allocated Value of the affected Subject Property (net of any Environmental Defect Amount withheld at Closing) and to immediately reassign the affected Subject Property to Seller if such property had been previously assigned to Buyer.

(d) Definition of Environmental Defect and Environmental Defect Amount. As used herein, an “Environmental Defect” shall mean a condition affecting a Subject Property that is a violation of Environmental Law or that requires remediation (whether currently or solely with the passage of time) under Environmental Law and which would cost, on an individual basis, in excess of twenty thousand dollars ($20,000.00) to remediate or, in the aggregate for all Subject Properties, in excess of Two Hundred Sixty Thousand dollars ($260,000.00) to remediate. As used herein, “Environmental Defect Amount” shall mean the cost or amount required to reasonably address an Environmental Defect in accordance with Environmental Laws and otherwise cure such Environmental Defect and bring the Subject Property affected by such Environmental Defect into compliance with Environmental Laws.

(e) Definition of Environmental Laws. As used herein, the term “Environmental Laws” shall mean any and all federal, state and local statutes, regulations, rules, orders, ordinances or permits of any governmental authority pertaining to health, the environment, wildlife and natural resources in effect in any and all jurisdictions in which the Subject Property is located, including without limitation, the Clean Air Act, as amended, and the Federal Water Pollution Control Act, as amended, the Oil Pollution Act of 1990 (“OPA90”), as amended, the Rivers and Harbors Act of 1899, as amended, the Safe Drinking Water Act, as amended, the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), as amended, the Superfund Amendments and Reauthorization Act of 1986 (“XXXX”), as amended, the Resource Conservation and Recovery Act (“RCRA”), as amended, the Hazardous and Solid Waste Amendments Act of 1984, as amended, the Toxic Substances Control Act, as amended, the Occupational Safety and Health Act (“OSHA”), as amended, and the Hazardous Materials Transportation Act, as amended.

(f) Environmental Arbitration. If Seller and Buyer are unable to agree before Closing on the existence or extent of a claimed Environmental Defect or the Environmental Defect Amount of an Environmental Defect, or on whether an Environmental Defect was properly claimed under Section 7(b), then, subject to Seller’s right before Closing to elect to retain a Subject Property affected by an Environmental Defect under Section 7(c), Buyer’s good faith estimate of each Environmental Defect and Environmental Defect Amount shall be used for purposes of calculating the downward adjustments to the Purchase Price made in the Closing Settlement Statement under Section 10(a), and the Environmental Defects and Environmental Defect Amounts in dispute shall be exclusively and finally resolved by the Environmental Expert (as defined below) pursuant to this Section 7(f). Likewise, if Seller has provided notice prior to the Closing Date of Seller’s intent to attempt to cure an Environmental Defect and by the end of the applicable cure period, Seller and Buyer have been unable to agree upon whether such Environmental Defect has been cured, or Seller has failed to cure any Environmental Defects which it provided notice that it would attempt to cure and Seller and Buyer have been unable to agree on the Environmental Defect Amounts for such Environmental Defects, then the cure and/or Environmental Defect Amounts in dispute shall be exclusively and finally resolved by the Environmental Expert pursuant to this Section 7(f). The “Environmental Expert” shall be a reputable environmental consulting or engineering firm approved in writing by Seller and Buyer fifteen (15) days

after the end of the cure period described in Section 7(c) (or such other time as mutually agreed), which firm shall have at least ten (10) years’ experience in performing or supervising environmental assessments on oil and gas properties in Montana. Absent such agreement on the selection of the Environmental Expert, the Environmental Expert shall be selected by the Denver, Colorado office of the American Arbitration Association. After selection of the Environmental Expert, the Parties shall promptly submit the matters in dispute and all relevant materials to the Environmental Expert, whose determination shall be made within twenty (20) days (or if not possible, as soon as possible thereafter) after such submission and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Expert shall be bound by the terms set forth in this Section 7(f) and Sections 7(b), 7(c), 7(d) and 7(e) and may consider such other matters as in the opinion of the Environmental Expert are necessary or helpful to make a proper determination. Additionally, the Environmental Expert may consult with and engage disinterested third parties to advise the Environmental Expert. Notwithstanding the foregoing, the Environmental Expert shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and Environmental Defect Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each Party shall bear one-half of the costs and expenses of the Environmental Expert.

Buyer shall be solely responsible for the proper distribution of such Suspended Proceeds (to the extent paid or credited to Buyer by Seller) to the party or parties which or who are entitled to receive payment of the same. At Closing, Seller shall provide to Buyer the list of interest owners and corresponding amounts of Suspended Proceeds attributable thereto.

For purposes of this definition, “control” means, when used with respect to any Person, the possession, directly or indirectly, of the power to direct or cause the direction of the management of such Person, whether through ownership of voting securities, by contract, or otherwise.

Nothing herein shall prevent a Selling Party or its Affiliates from (a) the sale or purchase or marketing of severed Hydrocarbons, (b) acquiring oil and gas leases or other mineral interest as part of a single transaction or series of related transactions, where the interests acquired in such transaction that would otherwise constitute a Restricted Opportunity under this Agreement (i) represent in the aggregate less than five percent (5%) of (x) the value of all the assets acquired in such transaction and (y) the aggregate amount of net acres acquired in such transaction, or (c) owning, or engaging in leasing or conveying activities relating to, mineral fee interests owned by Selling Parties that are not being conveyed hereunder (collectively, the “Reserved Interests”).

(j) Seismic Data. The Parties acknowledge that the Records shall include all of Seller’s right, title and interest in and to any seismic, geological or geophysical data relating to the Leases or Lands (“Seismic Data”).

11. Post-Closing Covenants.

(a) Final Settlement Statement. Not more than one hundred and twenty (120) days after the Closing, Seller shall prepare and deliver to Buyer, in accordance with this Agreement, a Final Settlement Statement setting forth each adjustment or payment which was not finally determined as of the Closing in the Closing Settlement Statement under Sections 10(a) and 10(b) and showing the calculation of such adjustments. As soon as practicable after receipt of the Final Settlement Statement, Buyer shall deliver to Seller a written report containing any changes which Buyer proposes be made to the Final Settlement Statement. The Parties shall undertake to agree with respect to the amounts due pursuant to such post-Closing adjustments no later than one hundred and fifty (150) days after the Closing. The date upon which such agreement is reached or upon which the final adjusted Purchase Price is otherwise established pursuant to this paragraph (the “Final Purchase Price”) shall be called the “Final Settlement Date”. In the event that the Parties cannot agree on the Final Purchase Price within one hundred and fifty (150) days after the Closing, such determination will be automatically referred to an independent expert of the Parties’ choosing with at least ten (10) years of oil and gas accounting experience for arbitration (the “Independent Expert”). If the Parties are unable to agree upon an Independent Expert, then such Independent Expert shall be selected by the Denver, Colorado office of the American Arbitration Association. The Independent Expert shall conduct the arbitration proceedings in Denver, Colorado in

accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Independent Expert’s determination shall be made within thirty (30) days after submission of the matters in dispute (or if not possible, as soon as possible thereafter) and shall be final and binding on both Parties, without right of appeal. In determining the proper amount of any adjustment to the Purchase Price, the Independent Expert shall not increase the Purchase Price more than the increase proposed by Seller nor decrease the Purchase Price more than the decrease proposed by Buyer, as applicable. The Independent Expert shall act as an expert for the limited purpose of determining the specific disputed adjustments to the Purchase Price submitted by either Party and may not award damages or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each Party shall bear one-half of the costs and expenses of the Independent Expert. In the event that (1) the Final Purchase Price is more than the amount paid to Seller at Closing, Buyer shall pay to Seller in immediately available funds the amount of such difference, or (2) the Final Purchase Price is less than the amount paid to Seller at Closing, Seller shall pay to Buyer in immediately available funds the amount of such difference. Payment by Buyer or Seller shall be made within five business days of the Final Settlement Date.

(b) Additional Payments Received. After the Final Settlement Date, Seller covenants and agrees that it will hold and promptly transfer and deliver to Buyer, from time to time as and when received by it, any cash, checks with appropriate endorsements (using its reasonable efforts not to convert such checks into cash), or other property that it may receive which properly belongs to Buyer, and will account to Buyer for all such receipts.

(c) Assumption of Obligations. After the Closing, subject to and without limiting Buyer’s rights under the other provisions of this Agreement, including without limitation with respect to Title Defects under Section 6, Environmental Defects under Section 7, indemnification under Section 15(a), and termination under Section 16, Buyer assumes, will be bound by, and agrees to perform (i) all express and implied covenants and obligations of Seller attributable to periods occurring from and after the Effective Date relating to the Subject Property, whether arising under (1) the Leases, prior assignments of the Leases, the Contracts, the Easements, the Permits or any other contractually-binding arrangements (to the extent such other arrangements are set forth in Exhibit “A” or Exhibit “C”) to which the Subject Property (or any component thereof) may be subject and which will be binding on Buyer and/or the Subject Property (or any component thereof) after the Closing or (2) any applicable laws, ordinances, rules and regulations of any governmental or quasi-governmental authority having jurisdiction over the Subject Property, or (ii) Seller’s proportionate part of the expenses and costs of plugging and abandoning the Xxxxx and restoration of operation sites, all in accordance with the applicable laws, regulations and contractual provisions. Subject to and without limiting Buyer’s rights under the other provisions of this Agreement, including without limitation with respect to Title Defects under Section 6, Environmental Defects under Section 7, indemnification under Section 15(a), and termination under Section 16, after Closing, Buyer shall assume the risk of any change in the condition of the Subject

Property from the Effective Date to the Closing, except to the extent any change of condition is attributable to the willful misconduct or gross negligence of Seller.

Buyer understands that the Subject Property is subject to all existing (to the extent in force and effect) Contracts relating to the Subject Property. Buyer shall assume and be responsible for all such obligations of Seller accruing on or after the Effective Date under such existing Contracts. Buyer shall assume all rights and duties of the operator of any of the Subject Properties which are operated by Seller and for which Buyer is elected the operator with respect to all duties and obligations of such operator accruing on or after the effective date of the election of Buyer as operator.

12. Costs and Revenues After Effective Date. Seller shall be responsible for the payment of all costs, liabilities and expenses incurred in the ownership and operation of the Subject Property prior to the Effective Date and not yet paid or satisfied. Buyer shall be responsible for payment (at Closing or thereafter if not reflected on the Preliminary Closing Settlement Statement) of all costs, liabilities and expenses incurred in the ownership and operation of the Subject Property after the Effective Date to the Closing Date. Such costs and expenses shall include any necessary and reasonable expenses incurred by Seller in the operation, protection or maintenance of the Subject Property. All hydrocarbons produced from the Subject Property prior to the Effective Date and all proceeds from the sale thereof, and all other income, proceeds, receipts and credits earned with respect to the Subject Property before the Effective Date, shall be the property of Seller. All hydrocarbons produced after the Effective Date and all other income, proceeds, receipts and credits earned with respect to the Subject Property after the Effective Date shall be the property of Buyer. Seller shall remit production proceeds, if any, received by Seller from sale of hydrocarbons, and all other income, proceeds or receipts belonging to Buyer hereunder, less expenses which Buyer is responsible for paying pursuant to this section, to Buyer immediately upon receipt. To the extent reasonably practicable, adjustments shall be made to the Purchase Price to account for such costs and revenues in the Preliminary Settlement Closing Statement or if not liquidated by such date, in the Final Settlement Statement.

13. Casualty Loss. If, prior to the Closing Date, any portion of the Subject Property shall be destroyed by fire or other casualty, Buyer shall have the right to treat such affected property as a Title Defect under Section 6 above for which the Title Defect Amount shall equal the amount reasonably required to repair or restore the affected Subject Property. Notwithstanding the foregoing, should the portion of Subject Property affected be material in Buyer’s reasonable opinion, Buyer shall have the right to exclude the affected Subject Property from this Agreement by giving notice thereof to Seller, in which event the Purchase Price shall be reduced by the Allocated Value of the affected Subject Property, or if there is no Allocated Value, both Parties shall negotiate in good faith any adjustment to the Purchase Price to account for the casualty loss.

14. Independent Investigation and Disclaimer. The express representations of Seller set forth in this Agreement are exclusive and in lieu of any and all other representations. EXCEPT FOR THE EXPRESS REPRESENTATIONS, WARRANTIES AND INDEMNITIES OF SELLER SET FORTH IN THIS AGREEMENT OR THE ASSIGNMENT, SELLER DISCLAIMS ALL LIABILITY AND RESPONSIBILITY FOR ANY OTHER

REPRESENTATION, WARRANTY, STATEMENT OR INFORMATION MADE OR COMMUNICATED (ORALLY OR IN WRITING) TO BUYER, INCLUDING ANY STATEMENTS, REPRESENTATIONS, OPINIONS, INFORMATION OR ADVICE WHICH MAY HAVE BEEN PROVIDED AS AN ACCOMMODATION TO BUYER BY AN OFFICER, SHAREHOLDER, DIRECTOR, EMPLOYEE, AGENT, CONSULTANT OR REPRESENTATIVE OF SELLER, OR ANY ENGINEER OR ENGINEERING FIRM, OR ANY OTHER AGENT, CONSULTANT, OR REPRESENTATIVE. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT OR THE ASSIGNMENT, SELLER MAKES ABSOLUTELY NO REPRESENTATION OR WARRANTY, EXPRESS, IMPLIED OR STATUTORY, AS TO (a) TITLE TO ANY OF THE SUBJECT PROPERTY, (b) THE ABILITY OF ANY COMPONENT OF THE SUBJECT PROPERTY TO PRODUCE ANY HYDROCARBONS, (c) THE AMOUNTS, QUALITY OR DELIVERABILITY OF HYDROCARBON RESERVES ATTRIBUTABLE TO THE SUBJECT PROPERTY, OR ANY PART THEREOF, (d) GEOLOGICAL GEOPHYSICAL OR OTHER INTERPRETATION OF ANY ECONOMIC EVALUATION, (e) PRESENT OR FUTURE SALES PRICES, OPERATING COSTS, OR OTHER ECONOMIC FACTORS, OR (f) THE CONDITION OR STATE OF REPAIR OF ANY WELL OR EQUIPMENT RELATING TO THE SUBJECT PROPERTY. SUBJECT TO THE EXPRESS REPRESENTATIONS, WARRANTIES AND INDEMNITIES OF SELLER SET FORTH IN THIS AGREEMENT OR THE ASSIGNMENT, BUYER ACKNOWLEDGES AND AFFIRMS THAT IT HAS EXERCISED ITS RIGHT TO INSPECT THE SUBJECT PROPERTY, AND EACH COMPONENT THEREOF; HAS SATISFIED ITSELF AS TO ITS PHYSICAL AND ENVIRONMENTAL CONDITIONS, BOTH SURFACE AND SUBSURFACE; AND FURTHER THAT BUYER HAS MADE ITS OWN INDEPENDENT INVESTIGATION, ANALYSIS AND EVALUATION OF THE SUBJECT PROPERTY, AND EACH COMPONENT THEREOF (INCLUDING BUYER’S OWN ESTIMATE AND APPRAISAL OF THE EXTENT AND VALUE OF THE PETROLEUM, NATURAL GAS AND OTHER HYDROCARBON RESERVES RESPECTING EACH COMPONENT OF THE SUBJECT PROPERTY). EXCEPT FOR THE EXPRESS REPRESENTATIONS, WARRANTIES AND INDEMNITIES OF SELLER SET FORTH IN THIS AGREEMENT OR THE ASSIGNMENT, THE PERSONAL PROPERTY (SURFACE AND SUBSURFACE) CONVEYED AS PART OF THE SUBJECT PROPERTY ARE SOLD HEREUNDER “WHERE IS, AS IS, WITH ALL FAULTS”, AND WITHOUT ANY WARRANTIES OR REPRESENTATIONS OF ANY KIND OR CHARACTER, EXPRESS OR IMPLIED OR STATUTORY, REGARDING THE CONDITION OR STATE OF REPAIR OF ANY OF THE EQUIPMENT COMPRISING PART OF THE SUBJECT PROPERTY.

15. Indemnification.

(a) By Seller. From and after Closing, except as specifically provided herein, Seller agrees to indemnify and hold harmless Buyer, its Affiliates and each of their officers, directors, employees and agents (“Buyer Indemnitees”), from all claims, losses, costs, liabilities and expenses (including reasonable attorneys’ fees and costs) arising out of or resulting from (i) until the first anniversary of the Closing Date, the ownership or operation of the Subject Property prior to the Closing Date, including without limitation Environmental Defects and Environmental Defect Amounts subject to Sections 15(d) in existence prior to the Closing Date (to the extent not waived by Buyer pursuant to

Section 7(b)), (ii) any breach by Seller of a representation or warranty of Seller under this Agreement, (iii) any breach by Seller of any of its covenants or agreements under this Agreement, (iv) the Excluded Properties (v) the ownership or operation of the Xxxxxx Interests during any time period or (vi) the suits, claims, actions and other proceedings disclosed in Schedule 4(i). The foregoing indemnity shall be limited to an aggregate amount equal to twenty percent (20%) of the Purchase Price, except for indemnification for the following which shall not be subject to such twenty percent (20%) of the Purchase Price limitation: Environmental Defects (and Environmental Defect Amounts), Excluded Properties, the suits, claims, actions and other proceedings disclosed in Schedule 4(i), breaches of Seller’s representations and warranties under Sections 4(a), 4(c), 4(f) and 4(g), Taxes that are the responsibility of Seller under this Agreement, or Subject Properties conveyed by Buyer to Seller pursuant to Section 15(d).

(b) By Buyer. From and after Closing, except as specifically provided herein, Buyer agrees to indemnify and hold harmless Seller, its Affiliates and each of their officers, directors, employees and agents (“Seller Indemnitees”), from all claims, losses, costs, liabilities and expenses (including reasonable attorneys’ fees and costs) arising out of or resulting from (i) Buyer’s ownership or operation of the Subject Property after the Closing Date, (ii) any breach by Buyer of a representation or warranty of Buyer under this Agreement or (iii) any breach by Buyer of any of its covenants or agreements under this Agreement.

(c) Procedure. Any claims for indemnification made under this Section 15 shall be made in accordance with and governed by the procedures set forth on Exhibit “E” attached hereto.

(d) Environmental Defects. If after Closing and prior to the first anniversary date of the Closing, Buyer asserts a claim for indemnity for an Environmental Defect or Environmental Defect Amount that was not waived pursuant to Section 7(b), the following shall apply:

(i) If the aggregate Environmental Defect Amounts for the Environmental Defects for which Buyer has asserted claims for indemnity hereunder (including the amount of a then current claim being asserted) are less than or equal to four million dollars ($4,000,000.00), then to the extent Buyer is entitled to be indemnified under this Agreement for such Environmental Defects and Environmental Defect Amounts, Seller shall pay such Environmental Defect Amounts to Buyer and Buyer shall perform the work necessary to cure or remedy the Environmental Defects giving rise to such Environmental Defect Amounts.

(ii) If the aggregate Environmental Defect Amounts for the Environmental Defects for which Buyer has asserted claims for indemnity hereunder (including the amount of a then current claim being asserted) are greater than four million dollars ($4,000,000.00), then to the extent Buyer is entitled to be indemnified under this Agreement for such Environmental Defects and Environmental Defect Amounts, Seller shall have the option, in its sole discretion to either (1) pay Buyer the amount of such Environmental Defect

Amounts in which case Buyer shall perform the work necessary to cure or remedy the Environmental Defects giving rise to such Environmental Defect Amounts, or (2) require Buyer to convey to Seller, effective as of the Effective Date, the portions of the Subject Properties to the extent affected by such Environmental Defect and pay to Buyer the Allocated Values of such Subject Properties (as limited to the affected portions), subject to appropriate adjustments to such Allocated Values as set forth in Section 10(a) for the period from the Effective Date to the date of such conveyance. Such conveyance shall be without representation or warranty except as to lawful claims of persons claiming by, through or under Buyer but not otherwise. If the portion of a Subject Property to be conveyed by Buyer to Seller includes a Lease, Fee Interest or Unit, the conveyance of such portion of the Subject Property by Buyer to Seller pursuant to this Section 15(d)(ii) shall be limited to the wellbore of any Xxxxx located on such portion of the Subject Property as of the Effective Date and to production from the wellbore of such Well attributable to the subsurface intervals (or the stratigraphic equivalent thereof) from which such Well was producing at the Effective Date, and in such case, Buyer shall retain all rights in such Lease, Fee Interest or Unit, including without limitation, as to all other depths and intervals covered by such Subject Property. Further, if the portion of a Subject Property to be conveyed by Buyer to Seller hereunder includes a Lease, Fee Interest or Unit but there was no Well located on the lands covered by such portion as of the Effective Date, the conveyance made hereunder shall be limited to the lands affected by the applicable Environmental Defect(s) giving rise to such conveyance, provided that Buyer shall retain all rights in and to, and the lands covered by, such Lease, Fee Interest and/or Unit, including without limitation all rights of ingress and egress for the purpose of drilling, exploration, operating and developing such lands and interests for oil, gas and other hydrocarbons and storing, handling, transporting and marketing the same. With respect to any Subject Property (or portion thereof) conveyed by Buyer to Seller pursuant to this Section 15(d)(ii), Seller shall indemnify Buyer for all obligations and liabilities relating to such Subject Property or portion as if such Subject Property or portion was an Excluded Property, including from the Environmental Defects and for Environmental Defect Amounts which gave rise to Seller’s election under this Section 15(d).

16. Termination. Subject to Section 16(a), this Agreement shall be terminated: (i) at any time prior to Closing by the mutual prior written consent of Seller and Buyer; (ii) by Seller or Buyer if Closing has not occurred on or before December 31, 2010 (the “Termination Date”); (iii) by Buyer if any condition set forth in Section 9(b) has not been satisfied or waived at Closing, (iv) by Seller if any condition set forth in Section 9(a) has not been satisfied or waived at Closing or (v) by Seller if the execution and delivery of this Agreement has not been approved by the board of directors of Buyer on or before November 29, 2010; provided, however, that termination under clauses (ii), (iii), (iv), or (v) shall not be effective until the Party electing to terminate has delivered written notice to the other Party of its election to so terminate.

(a) Effect of Termination. If this Agreement is terminated pursuant to Section 16, this Agreement shall become void and of no further force or effect (except

for the provisions of Sections 4(g), 5(e), 17(b), 17(f) and 17(g) which shall continue in full force and effect). Notwithstanding anything to the contrary in this Agreement, the termination of this Agreement under Section 16(ii) shall not relieve any Party from liability for any failure to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed at or prior to Closing.

(b) Specific Performance. If Seller or Buyer is eligible to terminate this Agreement under Section 16(ii) or (iii) (whether or not Seller or Buyer has claimed prior termination under Section 16(ii), (iii) or (iv)), the other Party has performed or is ready, willing and able to perform all of its agreements and covenants contained herein which are to be performed or observed at or prior to Closing, and Seller or Buyer has failed to perform or observe in any material respects any of its agreements or covenants contained herein which are to be performed or observed at or prior to Closing, then in lieu of termination of this Agreement, Seller or Buyer shall be entitled to specific performance of this Agreement, it being specifically agreed that monetary damages may not be sufficient to compensate Seller or Buyer.

17. Miscellaneous.

(a) Further Assurances. Seller agrees to execute any documents which it has the authority to execute, whether before or after the Closing, to aid Buyer in clearing or perfecting title and ownership to the Subject Property, and assuming duties as operator of Subject Property, and to facilitate the receipt of the proceeds of the sale of the production therefrom and attributable thereto. Buyer shall make any request for execution of such document in writing and shall provide Seller with a copy of the document.

(b) Entire Agreement.

Notwithstanding any provision hereof or of the Assignment, the Assignment and Xxxx of Sale or the Quitclaim Mineral Deeds, the terms and provisions of this Agreement shall survive the execution and delivery of such Assignment, Assignment and Xxxx of Sale and Quitclaim Mineral Deeds and shall remain in force and effect in accordance with the terms of this Agreement.

Seller’s indemnity in Section 15(a)(i) shall terminate on the first anniversary of the Closing Date, after which time no claim with respect thereto may be made thereunder, provided that there shall be no termination of any bona fide claim asserted under such indemnity prior to its termination. Buyer’s indemnity in Section 15(b)(i), and Seller’s indemnities in Sections 15(a)(iv), 15(a)(v), 15(a)(vi) and 15(d) (in respect of any Subject Property conveyed by Buyer to Seller pursuant to Section 15(d)) shall survive the Closing without time limit; provided, further, that the foregoing shall in no event constitute a waiver of any applicable statute of limitations.

(i) Assignment. Neither Party may assign its rights or delegate its duties hereunder except with the prior, written consent of the other Party, provided that nothing

herein shall prevent Buyer from selling or transferring any interest in the Subject Property to any other party after Closing.

(s) Seller’s Representative. Each Selling Party (other than Lario Oil & Gas Company, DEOSH Limited Partnership) hereby appoints and designates, Xxxx, as its agent and representative, with full power and authority to give and receive notices on behalf of Seller under this Agreement, provide negotiate and agree to the Preliminary Closing Settlement Statement and Closing Settlement Statement, make, receive and settle post Closing claims for indemnity, including without limitation, elections under Section 15(d), and take such other actions which a Selling Party or Seller is entitled to take under this Agreement or any other agreement executed and delivered pursuant to this
