(5)                                 An amount equal to sum of the unbilled costs for the joint interest ▇▇▇▇▇▇▇▇ paid by Seller and, the accounts receivable, for the joint interest ▇▇▇▇▇▇▇▇ paid by Seller on behalf of third party working interest owners, each as of the Closing Date, in the Leases, ▇▇▇▇▇ or Units; and

(6)                                 Any other amount agreed to by Buyer and Seller.

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

(1)                                 The amount required to be paid by Seller to Buyer under Section 4.2(i), if any;

(2)                                 An amount equal to the Environmental Adjustment Amount, if any, pursuant to Section 5.4;

(3)                                 The Allocated Value of those Assets not conveyed at Closing due to Seller withholding its consent to an Inspection Request in accordance with Section 3.3(a);

(4)                                 The Allocated Value of those Assets not conveyed at Closing due to the failure to obtain a consent to assign in accordance with Section 4.4(a) or the exercise of any preferential rights to purchase in accordance with Section 4.4(b);

(5)                                 Any proceeds of Hydrocarbons produced from and after the Effective Time, net of royalties, overriding royalties, net profit payments and similar burdens and Production Taxes, received by Seller between the Effective Time and Closing relating to the Assets;

11

(6)                                 An amount equal to the revenue held in suspense by Seller, as of the Closing Date, for royalties, overriding royalties and similar leasehold burdens and handled in accordance with Section 8.1(e);

(7)                                 An amount equal to the Allocated Value of the Assets affected by any Casualty Loss, or an amount equal to any Net Casualty Loss, pursuant to Section 8.3(b); and

(8)                                 Any other amount agreed to by Buyer and Seller.

(c)                                  Pipeline and Well Imbalance Adjustments.  The Parties agree that in calculating the Closing Amount, the Purchase Price will be adjusted downward or upward, as appropriate, for pipeline and well imbalances related to the Assets, if any, as follows:  The sum of all gas underproduction imbalances less the sum of all overproduction imbalances is herein called the “Net Imbalance” and the “Net Imbalance Amount” (which may be a positive or negative dollar amount) means the Net Imbalance multiplied by $3.55 per Mcf.

2.7.                            Proration of Costs and Revenues.

(a)                                 For purposes of determining the amounts of the adjustments to the Purchase Price provided for in Section 2.6, the principles set forth in this Section 2.7(a) shall apply.  Buyer shall be entitled to all production of Hydrocarbons from or attributable to the Leases, Lands, and ▇▇▇▇▇ at and after the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets at or after the Effective Time, and shall be responsible for (and entitled to any refunds with respect to) all Property Expenses incurred at and after the Effective Time.  Seller shall be entitled to all Hydrocarbon production from or attributable to Leases, Lands, and ▇▇▇▇▇ prior to the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time, and shall be responsible for (and entitled to any refunds with respect to) all Property Expenses incurred prior to the Effective Time.  “Earned” and “incurred”, as used in the Agreement shall be interpreted in accordance with generally accepted accounting principles and Council of Petroleum Accountants Society standards, and expenditures that are incurred pursuant to an operating agreement, unit agreement or similar agreement shall be deemed incurred when expended by the operator of the applicable Lease, Land or Well, in accordance with Seller’s then current practice.  For purposes of allocating production (and accounts receivable with respect thereto), under this Section 2.7(a), (i) liquid Hydrocarbons shall be deemed to be “from or attributable to” the Leases, Lands, and ▇▇▇▇▇ when they pass through the inlet flange of the pipeline connecting into the storage facilities into which they are run or, if there are no such storage facilities, when they pass through the LACT meters or similar meters at the initial point of entry into the pipelines through which they are transported from the field, and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Leases, Lands, and ▇▇▇▇▇ when they pass through the royalty measurement meters, delivery point sales meters or custody transfer meters on the gathering lines or pipelines through which they are transported (whichever meter is closest to the well).  Seller shall utilize reasonable interpolative procedures, consistent with industry practice, to arrive at an allocation of production when exact meter readings or gauging and strapping data are not available.  As part of Preliminary Settlement Statement, Seller

12

shall provide to Buyer such data that Seller determines in its discretion is necessary to support any estimated allocation, for purposes of establishing the Closing Amount.

(b)                                 Should Buyer receive after Closing any proceeds, income or other amounts to which Seller is entitled under Section 2.7(a), Buyer shall fully disclose, account for and promptly remit the same to Seller.  If, after Closing, Seller receives any proceeds, income or other amounts with respect to the Assets to which Buyer is entitled pursuant to Section 2.7(a), Seller shall fully disclose, account for, and promptly remit the same to Buyer.

(c)                                  Should Buyer pay after Closing any Property Expenses for which Seller is responsible under Section 2.7(a), Seller shall reimburse Buyer promptly after receipt of an invoice with respect to such Property Expenses, accompanied by copies of the relevant vendor or other invoice and proof of payment.  Should Seller pay after Closing any Property Expenses for which Buyer is responsible under Section 2.7(a), Buyer shall reimburse Seller promptly after receipt of an invoice with respect to such Property Expenses, accompanied by copies of relevant vendor or other invoice and proof of payment.

(d)                                 After Closing, Buyer shall handle all joint interest audits and other audits of Section 2.7(a Property Expenses covering the period for which Seller is in whole or in part responsible under), provided that Buyer shall not agree to any adjustments to previously assessed costs for which Seller is liable without the prior written consent of Seller. Buyer shall provide Seller with a copy of all applicable audit reports and written audit agreements received by Buyer and relating to periods for which Seller is wholly or partially responsible.

ARTICLE 3.

BUYER’S INSPECTION

3.1.                            Due Diligence.  Subject to Section 3.3, upon execution of this Agreement, Seller will make the Assets available to Buyer and its representatives for inspection and review, at Buyer’s sole cost, to permit Buyer to perform its due diligence (“Due Diligence Review”) as hereinafter provided.  Buyer shall be entitled to conduct its Due Diligence Review until 5:00 p.m. Mountain Time on June 28, 2013(the “Due Diligence Period”).  The notices pertaining to the Due Diligence Review for the Notice of Defective Interest and the Environmental Defect Notice must be received by Seller no later than 5:00 p.m. Mountain Time three Business Days after the expiration of the Due Diligence Period (the “Defect Notice Date”).

3.2.                            Access to Records.  Upon reasonable advance notice, the Records will be made available to Buyer at the offices of Seller during Seller’s normal business hours.  Notwithstanding the foregoing, Records relating to Non-Op Properties will only be made available to Buyer to the extent such Records are in Seller’s possession, provided that Seller will cooperate with and assist Buyer in obtaining copies of any Records not within Seller’s possession relating to the Non-Op Properties.

3.3.                            On-Site Inspection.

(a)                                 Seller hereby consents to Buyer conducting, during the Due Diligence Period and upon reasonable advance notice to Seller, at Buyer’s sole risk and expense, on-site inspections and a Phase One Environmental Assessment (an “Environmental Assessment”) of

13

the Assets; provided, Buyer’s right to conduct due diligence on Assets operated by any Person other than Seller (the “Non-Op Properties”) shall be subject to obtaining such operator’s consent, which Seller will use commercially reasonable efforts to obtain (but which efforts will not require Seller to pay any consent fee to the operator or agree to give such operator any other financial concession).  Buyer shall not conduct any sampling, boring, drilling or other invasive investigation activities upon the Assets (“Invasive Activities”) without the prior written consent of Seller, which consent will not be unreasonably withheld, and, with respect to any Non-Op Property, without the prior written consent of the third-party operator thereof, which Seller will use commercially reasonable efforts to obtain (but which efforts will not require Seller to pay any consent fee to the operator or agree to give such operator any other financial concession).  If any Environmental Assessment indicates that a Condition exists or is reasonably likely to exist on any Asset, Buyer may request Seller’s consent to conduct Invasive Activities (“Inspection Request”). The Inspection Request shall include the specific Asset that would be subject to the Invasive Activities, the reasons for requesting Invasive Activities and a description of the proposed Invasive Activities to be conducted by Buyer.  Seller shall consent to or deny the Inspection Request within three (3) Business Days of receipt of the Inspection Request, provided that consent from Seller shall not be unreasonably withheld and that the failure of Seller to respond within such three (3) Business Day period shall be deemed to constitute Seller’s denial of consent to the Inspection Request and the proposed Invasive Activities; provided further, Buyer’s right to conduct Invasive Activities on any Non-Op Property is also subject to the prior written consent of the third-party operator of such property, which Seller will use commercially reasonable efforts to obtain (but which efforts will not require Seller to pay any consent fee to the operator or agree to give such operator any other financial concession).  If Seller withholds its consent to any Inspection Request relating to an Asset with a Condition reasonably likely to exceed the Individual Environmental Threshold, then Buyer may elect to have Seller retain the entirety of any such Asset at the Closing, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Asset.

(b)                                 Seller shall have the right to have its representatives present at any time that Buyer or any of its representatives are present on the Assets, and Buyer will cooperate reasonably with Seller’s scheduling requests so Seller or its representatives can be present.   In connection with any Environmental Assessment or Invasive Activities, Buyer agrees not to interfere with the normal operation of the Assets and agrees to comply with all requirements and safety policies of the operator.  If Buyer or its agents prepares an Environmental Assessment or conducts Invasive Activities, Buyer will furnish a copy of the assessment or report resulting therefrom to Seller.  The Parties shall execute a “common undertaking” letter regarding the confidentiality of Environmental Assessments and Invasive Activities.

(c)                                  During the Due Diligence Period, upon reasonable advance notice, Seller shall provide Buyer with reasonable access to the persons set forth on Schedule 3.3(c) during normal business hours, and shall instruct such persons to cooperate in all reasonable respects with Buyer in its Due Diligence Review.  Notwithstanding the foregoing, in the event that Seller is prohibited under an agreement currently binding on Seller to provide Buyer access to an Asset or any Record, Seller’s obligation to provide Buyer access with respect to such Asset or Record shall be deemed satisfied by Seller using commercially reasonable efforts to obtain permission for Buyer or its representatives to gain such access.

14

(d)                                 As a condition to granting Buyer or any representative thereof access to any Asset (including for the purpose of conducting Invasive Activities), Buyer must present Seller with a customary insurance certificate confirming that it is adequately insured and including the insurer’s waiver of subrogation of Buyer’s or its representatives’ rights and claims against Seller.  In addition, as a condition to performing any Invasive Activities, such insurance certificate must show Seller as an additional insured.  Buyer hereby waives, releases and agrees to defend and indemnify Seller and its directors, officers, managers, employees, Affiliates, agents and representatives against all claims for injury to, or death of, persons or for damage to property arising in any way from the access afforded to Buyer hereunder or the activities of Buyer or its representatives (including Invasive Activities).  This waiver, release and indemnity by Buyer shall survive termination of this Agreement.

3.4.                            Disclaimer.  EXCEPT FOR THE SPECIFIC REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, SELLER MAKES NO WARRANTY OR REPRESENTATION OF ANY KIND AS TO ANY INFORMATION OBTAINED BY BUYER PURSUANT TO THIS ARTICLE 3, INCLUDING THE RECORDS AND ANY INFORMATION CONTAINED THEREIN.  BUYER AGREES THAT ANY CONCLUSIONS DRAWN FROM THE RECORDS SHALL BE THE RESULT OF ITS OWN INDEPENDENT REVIEW AND JUDGMENT.

ARTICLE 4.

TITLE MATTERS

4.1.                            Seller’s Title.

(a)                                 Limited Defensible Title Representation.  Seller represents to Buyer that (i) as of the Defect Notice Date its title to the Leases, ▇▇▇▇▇ and Units is Defensible Title, and (ii) to Seller’s Knowledge, as of the date hereof, Schedule 4.1(a) sets forth each individual Title Defect affecting any of the Leases, ▇▇▇▇▇ or Units with a Title Defect Amount in excess of the Individual Title Threshold.  Except as set forth in this Section 4.1(a) and in the Assignment, ▇▇▇▇ of Sale and Conveyance of Assets, attached hereto as Exhibit E, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to Seller’s title to the Leases, ▇▇▇▇▇, Units and other Assets.  Buyer hereby acknowledges and agrees that Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Leases, ▇▇▇▇▇, Units and other Assets and for any breach of Seller’s representations in this Section 4.1(a) shall be Buyer’s right to adjust the Purchase Price to the extent provided in this Article 4, and Buyer hereby releases and waives all other remedies and agrees not to assert or threaten to assert any claim with respect to any such waived remedies.  The representations in this Section 4.1(a) shall terminate as of the Defect Notice Date and shall have no further force and effect thereafter.

(b)                                 Defensible Title - Leases, ▇▇▇▇▇ and Units.  The term “Defensible Title” means such ownership of record to the Leases, ▇▇▇▇▇ and Units that is deducible from the applicable county, state and federal records such that a reasonably prudent person engaged in the business of the ownership, development and operation of oil and gas leasehold and properties and having knowledge of all of the facts and their legal bearing would be willing to accept the same, and that, subject to and except for Permitted Encumbrances as defined in Section 4.1(c):

15

(i)                                     entitles Seller to receive a share of the Hydrocarbons produced, saved and marketed from any Lease, Well or Unit throughout the duration of the productive life of such Lease, Well or Unit or such specified zone(s) therein after satisfaction of all royalties, overriding royalties, nonparticipating royalties, net profits interests or other similar burdens on or measured by production of Hydrocarbons (a “Net Revenue Interest”), of not less than the Net Revenue Interest share shown in Exhibit A or Exhibit B, respectively, for such Lease, Well or Unit;

(ii)                                  obligates Seller to bear a percentage of the costs and expenses for the maintenance, development, operation and the production relating to any Lease, Well or Unit throughout the productive life of such Lease, Well or Unit (“Working Interest”) not greater than the Working Interest shown in Exhibit A or Exhibit B, respectively, for such Lease, Well or Unit without increase, except increases to the extent that they are accompanied by a proportionate increase in Seller’s Net Revenue Interest;

(iii)                               each such Lease covers the Net Acre interest set forth in Exhibit A; and

(iv)                              is free and clear of Liens.

(c)                                  Permitted Encumbrances.  The term “Permitted Encumbrances” shall mean:

(1)                                 lessors’ royalties, overriding royalties, net profits interests, production payments, reversionary interests and similar burdens if the net cumulative effect of such burdens does not cause the Net Revenue Interest to be less than or the Working Interest to be more than as set forth in Exhibit A or Exhibit B, respectively, for the applicable Asset;

(2)                                 statutory liens for Taxes that are not yet due and payable or that are being contested in good faith in the normal course of business;

(3)                                 all rights to consent by, required notices to, filings with, or other actions by Governmental Entities, in connection with the conveyance of the applicable Asset if the same are customarily sought after such conveyance;

(4)                                 rights of reassignment contained in any Leases, or assignments thereof, providing for reassignment upon the surrender or expiration of any Leases;

(5)                                 easements, rights of way, servitudes, permits, surface leases and other rights with respect to surface operations, pipelines, grazing, logging, canals, ditches, reservoirs or the like, and easements for streets, alleys, highways, pipelines, telephone lines, power lines, railways and other easements and rights-of-way, on, over or in respect of any of the Assets or any restriction on access thereto that do not materially interfere with the operation of the affected Asset;

(6)                                 the terms and conditions of the Contracts listed in Exhibit C or any compulsory pooling order of the North Dakota Industrial Commission; provided, however, that the effect of any such items do not cause the Net Revenue Interest to be

16

less than or the Working Interest to be more than as set forth in Exhibit A or Exhibit B, respectively, for the applicable Asset;

(7)                                 materialmen’s, mechanics’, operators’ or other similar liens arising in the ordinary course of business (i) if such liens and charges have not been filed pursuant to law and the time for filing such liens and charges has expired, (ii) if filed, such liens and charges have not yet become due and payable or payment is being withheld as provided by law, or (iii) if their validity is being contested in good faith by appropriate action;

(8)                                 such Title Defects (as defined in Section 4.2(a)) as Buyer has waived;

(9)                                 any Liens burdening the Assets which will be released at or before Closing; and

(10)                          any items set forth on Schedule 4.2(a)(9).

4.2.                            Purchase Price Adjustment Procedures.

(a)                                 Title Defect.  As used in this Agreement, the term “Title Defect” means any Lien, obligation (including contract obligation), defect, or other matter (including without limitation a discrepancy in Net Revenue Interest or Working Interest) that causes a breach of Seller’s representation in Section 4.1(a) and that is not cured by Seller in the manner permitted by this Agreement.  Notwithstanding the foregoing, the following shall not be considered Title Defects:

(1)                                 defects based solely on lack of information in connection with documents filed of record not contained in Seller’s files;

(2)                                 defects in the chain of title consisting of the mere failure to recite marital status in a document or omissions of successions of heirship or estate proceedings, unless Buyer provides clear and convincing evidence that such failure or omission has resulted in another Person’s actual and superior claim of title to the relevant Asset;

(3)                                 defects arising out of lack of survey, unless a survey is expressly required by applicable laws or regulations;

(4)                                 defects asserting a change in Working Interest or Net Revenue Interest based on a change in drilling and spacing units, tract allocation or other changes in pool or unit participation occurring after the Effective Time by a party other than Seller;

(5)                                 defects arising out of lack of corporate or other entity authorization unless Buyer provides affirmative evidence that such corporate or other entity action was not authorized and results in another Person’s actual and superior claim of title to the relevant Asset;

17

(6)                                 Liens created under deeds of trust, mortgages and similar instruments by the lessor under a Lease covering the lessor’s surface and mineral interests in the land covered thereby which would customarily be accepted in taking oil and gas leases or purchasing undeveloped oil and gas leases and for which the lessee would customarily seek a subordination of such Lien to the oil and gas leasehold estate prior to conducting drilling activities on the Lease;

(7)                                 defects based on failure to record a Lease issued by the Bureau of Land Management or the North Dakota Board of University and School Lands, or any assignments of record title or operating rights in such Leases, in the real property, conveyance or other records of the county in which such Lease is located;

(8)                                 defects that have been cured by applicable laws of limitations, prescription or otherwise; and

(9)                                 any items set forth on Schedule 4.2(a)(9).

(b)                                 Title Benefit.  As used in this Agreement, the term “Title Benefit” shall mean any right, circumstance or condition that operates (i) to increase the Net Revenue Interest of Seller in any Lease, Well or Unit above that shown in Exhibit A or Exhibit B, respectively, to the extent the same does not cause a greater than proportionate increase in Seller’s Working Interest therein above that shown in Exhibit A or Exhibit B, respectively, (ii) to decrease the Working Interest of Seller in any Lease, Well or Unit below that shown in Exhibit A or Exhibit B, respectively, to the extent such decrease in Seller’s Working Interest is proportionately greater than the decrease in Seller’s Net Revenue Interest therein below that shown in Exhibit A or Exhibit B, respectively, or (iii) increase the Net Acres of Seller covered by the Lease above that shown in Exhibit A.

(c)                                  Notice of Defective Interest.  On or before the Defect Notice Date, Buyer shall notify Seller in writing of any matters that in Buyer’s reasonable opinion constitute a Title Defect with respect to Seller’s title to all or any portion of the Leases, ▇▇▇▇▇ and Units (“Notice of Defective Interests”).  The Notice of Defective Interests shall be in writing, shall identify the instrument as Buyer’s Notice of Defective Interests and shall contain the following: (i) a reasonably clear, complete and accurate description of the information in the possession of Buyer with respect to the alleged Title Defect(s), (ii) the Leases, ▇▇▇▇▇ or Units (and the applicable zone(s) therein) affected by the alleged Title Defect(s) (each a “Title Defect Property”), (iii) the Allocated Value of each Lease, Well or Unit subject to the alleged Title Defect(s), (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of the alleged Title Defect(s), and (v) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations and information upon which Buyer’s belief is based.  To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer shall make reasonable efforts to give Seller written notice of all Title Defects discovered by Buyer at the end of each calendar week during the Due Diligence Period; provided, however, any such written notice may be preliminary in nature and supplemented prior to the Defect Notice Date, and the failure to provide such preliminary notice shall not be deemed to waive or restrict Buyer’s rights hereunder with respect to such Title Defect.  Any matters that may otherwise

18

constitute a Title Defect, but of which Seller has not been notified by Buyer in accordance with this Section 4.2(c) prior to the Defect Notice Date, shall be deemed to have been waived by Buyer.

(d)                                 Notice of Title Benefits.  Buyer will promptly furnish Seller with written notice of any Title Benefit that is discovered by any of Buyer’s or any of its Affiliates’ employees, title attorneys, landmen or other title examiners while conducting Buyer’s Due Diligence Review prior to the Defect Notice Date.  On or before the Defect Notice Date, Seller shall have the right, but not the obligation, to advise Buyer in writing of any matters that in Seller’s reasonable opinion constitute a Title Benefit with respect to Seller’s title to all or any portion of the Leases, ▇▇▇▇▇ and Units (a “Title Benefit Notice”).  The Title Benefit Notice shall be in writing and contain the following: (i) a reasonably clear, complete and accurate description of the information in the possession of the party providing such notice with respect to the alleged Title Benefit(s), (ii) the Leases, ▇▇▇▇▇ or Units (and the applicable zone(s) therein) affected by the alleged Title Benefit(s), (iii) the Allocated Value of each Lease, Well or Unit (and the applicable zone(s) therein) subject to the alleged Title  Benefit(s), (iv) supporting documents reasonably necessary for such other party (as well as any title attorney or examiner hired by such other party) to verify the existence of the alleged Title Benefit(s), and (v) the amount by which the party providing such Title Benefit Notice reasonably believes the Allocated Value of such Leases, ▇▇▇▇▇ or Units (and the applicable zone(s) therein) is increased by the Title Benefit, and the computations and information upon which such belief is based.  Seller shall be deemed to have waived all Title Benefits of which it has not given notice on or before the Defect Notice Date.

(e)                                  Remedies for Title Defects.  Subject to Seller’s continuing right to title dispute resolution under Section 4.3, in the event that any Title Defect is timely asserted by Buyer in accordance with Section 4.2(c) and is not waived by Buyer or cured on or before Closing, Seller shall elect, in its sole discretion, from among the following:

(1)                                 Seller may convey the Title Defect Property to Buyer at Closing and reduce the Purchase Price by an amount determined pursuant to Section 4.2(i) and retain the right to cure the Title Defect after Closing;

(2)                                 Seller may exclude the Title Defect Property from the transaction and reduce the Purchase Price by an amount equal to the Allocated Value for such Title Defect Property (and the Individual Title Threshold and Aggregate Title Deductible shall be disregarded and therefore not applied for purposes of this Purchase Price reduction); or

(3)                                 with the consent of Buyer, make no adjustment to the Purchase Price and indemnify Buyer against all liability, loss, cost and expense resulting from such Title Defect, pursuant to the terms and conditions of the Indemnification Agreement attached hereto as Exhibit H.

(f)                                   Title Defect Amount.  The “Title Defect Amount” means the amount by which the Allocated Value of the Title Defect Property affected by such Title Defect is reduced

19

as a result of the existence of such Title Defect and shall be determined in accordance with the following methodology, terms and conditions:

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

(2)                                 if the Title Defect is a Lien that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount of the payment necessary to remove such Title Defect from the Title Defect Property; and

(3)                                 if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property of a type not described in subsections (1) or (2) above, the Title Defect Amount shall be determined by taking into account the following factors:  (i) any discrepancy between (A) the Net Revenue Interest or Working Interest for any Title Defect Property and (B) the Net Revenue Interest or Working Interest stated in Exhibit A or Exhibit B, respectively; (ii) the Allocated Value of the Title Defect Property; (iii) the portion of the Title Defect Property affected by the Title Defect; (iv) the legal effect of the Title Defect; (v) the values placed upon the Title Defect by Buyer and Seller; (vi) any discrepancy between (A) the Net Acre interest covered by a Lease and (B) the Net Acre interest covered by such Lease stated in Exhibit A; and (vii) such other reasonable factors as are necessary to make a proper evaluation.

Notwithstanding anything to the contrary in this Article 4, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of such Title Defect Property.

(g)                                  Individual Title Threshold.  Except as provided in Section 4.2(e)(2), (i) there shall be no adjustment (upwards or downwards) to the Purchase Price for any individual Title Defect or any individual Title Benefit, the Title Defect Amount of which or the Title Benefit Amount of which, respectively, does not exceed $100,000 (“Individual Title Threshold”).

(h)                                 Title Benefit Amount.  The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the same methodology, terms and conditions for determining the Title Defect Amount.

(i)                                     Title Adjustment Amount.  If the aggregate Title Defect Amount of all Title Defects (disregarding any Title Defect whose Title Defect Amount is less than $100,000) exceeds the aggregate Title Benefit Amount of all Title Benefits (disregarding any Title Benefit whose Title Benefit Amount is less than $100,000), then the Purchase Price shall be reduced to the extent (and only to the extent) such excess exceeds $9,900,000.  If the aggregate Title Benefit Amount of all Title Benefits (disregarding any Title Benefit whose Title Benefit Amount is less than $100,000) exceeds the aggregate Title Defect Amount of all Title Defects (disregarding any Title Defect whose Title Defect Amount is less than $100,000), then the Purchase Price shall be increased to the extent (and only to the extent) such excess exceeds $9,900,000.  The amount by which the Purchase Price is adjusted under this Section 4.2(i) shall be referred to as the “Title

20

Adjustment Amount,” and the Title Adjustment Amount shall be recalculated from time to time to take into account Title Defect cured in accordance with this Agreement and the resolution of Disputed Title Defects and Disputed Title Benefits.  Buyer, at its sole discretion, may elect to waive all or any portion of any Title Defect as to Buyer, so as to reduce the aggregate Title Adjustment Amount below the percentage that would prevent termination of this Agreement pursuant to Section 11.1 in which case any waived Title Defect (or portion thereof) shall no longer form the basis for a downward adjustment to the Purchase Price.

(j)                                    Seller’s Right to Cure.

(1)                                 Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove at any time prior to Closing (the “Cure Period”) any Title Defects of which it has been advised by Buyer.

(2)                                 Subject to the provisions of this Section 4.2, if there is a reduction in the Purchase Price pursuant to Section 4.2(i), then Seller shall retain the right but not the obligation for one hundred eighty (180) days after the Closing Date to attempt to cure any Title Defect at Seller’s sole cost.  At Seller’s request, Buyer will cooperate in all reasonable respects with Seller’s curative efforts.  If Seller cures any such Title Defect such that such Title Defect no longer exists or in a manner otherwise reasonably satisfactory to Buyer, then the Title Adjustment Amount shall be recalculated, and Buyer or Seller, as applicable, shall make a true-up payment to the other based on such recalculated Title Adjustment Amount and taking into account all prior adjustments to the Purchase Price based on Title Defects and Title Benefits. Amounts required to be paid by one party to the other pursuant to the preceding sentence shall first be satisfied from any Title Escrow Amount (and Buyer and Seller shall issue a joint instruction letter to the Escrow Agent regarding prompt payment of the Title Defect Amount in the amount of such true-up obligation to Seller).  If the Title Defect Amount is not sufficient to satisfy either party’s true-up obligation in full, such party shall satisfy the balance of such obligation by making an out of pocket cash payment to the other party.

4.3.                            Title Dispute Resolution.  The Parties agree to resolve disputes concerning the following matters pursuant to this Section 4.3:  (i) the existence and scope of a Title Defect, Title Benefit or Title Adjustment Amount, (ii) the Title Defect Amount of that portion of the Asset affected by a Title Defect and (iii) the adequacy of Seller’s Title Defect curative efforts as to whether such Title Defect continues to exist or Buyer’s reasonable satisfaction of such efforts (the “Title Disputed Matters”).  The Parties agree to attempt to initially resolve all Title Disputed Matters through good faith negotiations.  If the Parties cannot resolve a Title Defect or Title Benefit dispute on or before Closing (each, a “Disputed Title Defect” and a “Disputed Title Benefit,” respectively), solely for purposes determining the Closing Amount (and subject to true-up as such disputed items are resolved), the Title Adjustment Amount shall be calculated (x) as if Buyer’s position on each Disputed Title Defect were correct and as if Seller’s position with respect to each Disputed Title Benefit were correct (the “Closing Date Title Adjustment Amount”) and (y) as if Seller’s position on each Disputed Title Defect were correct and as if Buyer’s position with respect to each Disputed Title Benefit were correct (the “Hypothetical Title Adjustment Amount”).  The difference between the Closing Date Title Adjustment Amount and the Hypothetical Adjustment Amount representing the greatest dollar amount in

21

dispute, is referred to herein as the “Title Escrow Amount” and, at Closing, shall be paid by Buyer to the Escrow Agent to be held as part of the Additional Escrow Amount.  Further, the Title Disputed Matters will be finally determined by binding arbitration pursuant to Section 15.13, provided however, that the independent arbitrator appointed pursuant to Section 15.13 shall be an oil and gas title attorney licensed in North Dakota with a minimum of ten (10) years experience with title defects affecting the types of properties which are the subject of the Title Disputed Matters.  The arbitrator shall employ such independent attorneys, petroleum engineers and/or other consultants as deemed necessary.  On or before forty-five (45) days after Closing, Buyer and Seller shall present their respective positions in writing to the arbitrator, together with such evidence as each Party deems appropriate.  The arbitrator shall be instructed to resolve the dispute through a final decision within twenty (20) days after submission of the matters in dispute and the final decision may be reflected in the Final Settlement Statement.  Upon final resolution of each Title Disputed Matter, the Title Adjustment Amount shall be recalculated, and Buyer or Seller, as applicable, shall make a true-up payment to the other based on such recalculated Title Adjustment Amount and taking into account all prior adjustments to the Purchase Price and true-up payments based on the prior resolution and prior cure of all Titled Defects and Title Benefits.  Amounts required to be paid by one party to the other pursuant to the preceding sentence shall first be satisfied from any Title Escrow Amount (and Buyer and Seller shall issue a joint instruction letter to the Escrow Agent regarding prompt payment of the Title Defect Amount in the amount of such true-up obligation to Seller).  If the Title Escrow Amount is not sufficient to satisfy either party’s true-up obligation in full, such party shall satisfy the balance of such obligation by making an out of pocket cash payment to the other party.

4.4.                            Preferential Rights and Consents.  As of the date hereof, Seller has identified the preferential purchase rights and consents to assignment listed on Schedule 4.4 that may be triggered by the transactions contemplated by this Agreement. The remedies set forth in this Section 4.4 are the exclusive remedies under this Agreement for consents to assign and preferential rights to purchase affecting the Assets that are disclosed on Schedule 4.4 or are discovered by the Parties prior to the Closing.  An Asset affected by a Material Consent or preferential right to purchase that is outstanding at Closing shall be referred to as an “Affected Asset”.

(a)                                 Consents.  Promptly after execution hereof, Seller shall use commercially reasonable efforts to send notices to those Persons necessary to request all Material Consents to assignment of the Assets.  If prior to Closing, Seller fails to obtain a consent to assign that would invalidate the conveyance of the Asset affected by the consent to assign or materially affect the value or use of the Asset (a “Material Consent”) and the failure to obtain such Material Consent has not been waived by Buyer, then Seller shall retain the Affected Asset and the Purchase Price shall be reduced by the Allocated Value of the Affected Asset.  If such Material Consent is obtained on or before the Final Settlement Date, Seller shall convey the Affected Asset to Buyer effective as of the Effective Time and Buyer shall pay Seller the Allocated Value of the Affected Asset, in accordance with the terms and conditions of this Agreement.  If such Material Consent is not obtained on or before the Final Settlement Date, the Affected Asset shall be excluded from the sale and the Purchase Price shall be deemed to be reduced by an amount equal to the Allocated Value of the Affected Asset.  Buyer shall reasonably cooperate with Seller in obtaining any Material Consent, including providing assurances of reasonable financial

22

conditions, but Buyer shall not be required to expend funds or make any other type of financial commitments as a condition of obtaining such Material Consent.

(b)                                 Preferential Purchase Rights.  Seller shall use commercially reasonable efforts to give notices required in connection with preferential purchase rights prior to Closing.  If any preferential right to purchase any portion of the Assets is exercised prior to the Closing Date, then the Affected Assets shall be excluded from the sale and the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of such Affected Assets.  If by Closing, either (i) the time frame for the exercise of a preferential purchase right has not expired and Seller has not received notice of an intent not to exercise or a waiver of the preferential purchase right, or (ii) a third party exercises its preferential right to purchase, but the time frame for consummation of the preferential purchase right has not expired prior to the Closing, then Seller shall retain the Affected Assets and the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of such Affected Assets.  As to any Affected Assets retained by Seller hereunder, following Closing if a preferential right to purchase is not consummated within the time frame specified in the preferential purchase right, or if the time frame for exercise of the preferential purchase right expires without exercise after the Closing, Seller shall promptly convey the Affected Assets to Buyer, effective as of the Effective Time, and Buyer shall pay the Allocated Value thereof pursuant to the terms of this Agreement.

ARTICLE 5.
ENVIRONMENTAL MATTERS

5.1.                            Exclusive Remedy.  Section 5.4 shall be the exclusive right and remedy of Buyer with respect to the existence of any Condition or Seller’s failure to comply with Environmental Laws with respect to the Leases, ▇▇▇▇▇, Units and other Assets.  Seller represents to Buyer that, to Seller’s Knowledge, as of the date hereof, there is no individual Environmental Defect affecting any of the Assets with an Environmental Defect Amount in excess of the Individual Environmental Threshold. Buyer hereby acknowledges and agrees that Buyer’s sole remedy for any Environment Defect or breach of any representation in this Section 5.1 shall be the remedies provided in Section 5.4, and Buyer hereby releases and waives all other remedies and agrees not to assert or threaten to assert any claim with respect to any such waived remedies.  The representations in this Section 5.1 shall terminate as of the Defect Notice Date and shall have no further force and effect thereafter.

5.2.                            Environmental Liabilities and Obligations.  Upon Closing, Buyer agrees to assume and pay, perform, fulfill and discharge all Environmental Liabilities.  Any Environmental Defect raised by Buyer in an Environmental Defect Notice shall be an Environmental Liability, except with respect to Assets excluded from the transaction hereunder; provided, however, nothing in this Section 5.2 shall limit the ability of the Parties to adjust the Purchase Price pursuant to the terms of Section 5.4.

5.3.                            Environmental Defect Notice.  On or before the Defect Notice Date, Buyer shall notify Seller in writing of any matters that in Buyer’s reasonable opinion constitute an Environmental Defect (“Environmental Defect Notice”).  The Environmental Defect Notice shall be in writing, shall identify the instrument as Seller’s Environmental Defect Notice and contain the following: (i) a reasonably clear, complete and accurate description of the

23

information in the possession of Buyer with respect to the alleged Environmental Defect(s), (ii) the Assets affected by the alleged Environmental Defect(s) (each an “Environmental Defect Property”), (iii) the Allocated Value of each Environmental Defect Property, (iv) supporting documents reasonably necessary for Seller (as well as any consultant hired by Seller) to verify the existence of the alleged Environmental Defect(s), and (v) the amount by which Buyer reasonably believes the Allocated Value of each Environmental Defect Property is reduced by the alleged Environmental Defect(s) and the computations and information upon which Buyer’s belief is based.

5.4.                            Defect Adjustments.  Upon delivery of a timely Environmental Defect Notice, the Parties shall proceed as follows:

(a)                                 With respect to each Environmental Defect timely asserted by Buyer, Seller may, at its sole discretion, elect, on or prior to the Closing Date, to (1) reach agreement with Buyer on the existence of the Environmental Defect and an adjustment to the Purchase Price which shall be reflected on the Preliminary Settlement Statement, which adjustment shall reflect the cost to Remediate such Environmental Defect (“Environmental Defect Amount”); or (2) elect to challenge the existence and/or scope of the Environmental Defect and/or Environmental Defect Amount asserted by Buyer pursuant to this Section 5.4(a).  Notwithstanding anything to the contrary contained herein, in the event the Environmental Defect Amount reasonably asserted by Buyer in the Environmental Defect Notice exceeds the Allocated Value for such Environmental Defect Property, Buyer or Seller may elect to exclude the Environmental Defect Property from the transaction and reduce to the Purchase Price by the amount of the Allocated Value for such Environmental Defect Property, without giving effect to the Individual Environmental Threshold and Aggregate Environmental Deductible.  If Seller elects to challenge the existence and/or scope of the Environmental Defect and/or the Environmental Defect Amount pursuant to this Section 5.4 (the “Environmental Disputed Matters”), and such dispute has not been resolved as of the Closing Date and the parties have not elected to exclude the Environmental Defect Property from the transaction contemplated hereunder as provided in the proceeding sentence, then the Purchase Price shall be reduced by the Allocated Value of such Environmental Defect Property (such amount, the “Environmental Escrow Amount”), and, at Closing, Buyer shall pay such Environmental Escrow Amount to the Escrow Agent.  Further, the Environmental Disputed Matters will be finally determined by binding arbitration in accordance with the procedures set forth in Section 15.13.  With respect to disputes concerning Environmental Defects, the arbitrator shall be qualified by education, knowledge and experience with environmental defects affecting the types of properties which are subject to the disputed Environmental Defect or Environmental Defect Amount and have a minimum of ten (10) years experience with such types of defects and properties.  The arbitrator shall employ such independent attorneys and/or other consultants as deemed necessary.  On or before forty-five (45) days after Closing, Buyer and Seller shall present their respective positions in writing to the arbitrator, together with such evidence as each Party deems appropriate.  The arbitrator shall be instructed to resolve the dispute through a final decision within twenty (20) days after submission of the matters in dispute, and the final decision may be reflected in the Final Settlement Statement.  Upon final resolution of any Environmental Disputed Matter, the Escrow Agent shall, pursuant to Section 2.5, deliver the applicable Environmental Escrow Amount out of the Additional Escrow Amount in accordance with the decision of the arbitrator.

24

(b)                                 Except as otherwise provided herein, (i) there shall be no adjustments to the Purchase Price for any individual Environmental Defect for which the Environmental Defect Amount does not exceed $100,000 (“Individual Environmental Threshold”); and (ii) there shall be no adjustments to the Purchase Price for any Environmental Defect that exceeds the Individual Environmental Threshold unless the Environmental Defect Amount of all such Environmental Defects, in the aggregate, excluding any Environmental Defects cured by Seller, exceeds a deductible in an amount equal to $9,900,000 (the “Aggregate Environmental Deductible”), after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Environmental Defect Amounts in excess of such Aggregate Environmental Deductible (the “Environmental Adjustment Amount”); provided, however, that Buyer, at its sole discretion, may elect to waive all or any portion of any Environmental Defect as to Buyer, so as to reduce the aggregate Environmental Adjustment Amount below the percentage that would prevent termination of this Agreement pursuant to Section 11.1.

ARTICLE 6.
SELLER’S REPRESENTATIONS AND WARRANTIES

6.2.                            Power.  Seller has all requisite limited liability company power and authority to carry on its business as presently conducted, to enter into this Agreement, and to perform its obligations hereunder.  The execution and delivery of this Agreement does not, and the performance of Seller’s obligations hereunder will not, as of Closing, violate, or be in conflict with, any provision of Seller’s governing documents, or any judgment, decree, order, statute, rule or regulation applicable to Seller; provided, no representation is made in this Section 6.2 with respect to the assignability of the Assets under applicable law as such subject matter is covered exclusively by Sections 4.4 and 6.19.

6.3.                            Authorization and Enforceability.  Assuming the due authorization, execution and delivery by Buyer, this Agreement constitutes Seller’s legal, valid and binding obligation, enforceable in accordance with its terms, subject, however, to the effects of bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and other laws for the protection of creditors, as well as to general principles of equity, regardless whether such enforceability is considered in a proceeding in equity or at law.

25

6.4.                            Liability for Brokers’ Fees.  Seller has not incurred any liability, contingent or otherwise, for investment bankers’, brokers’ or finders’ fees relating to the transactions contemplated by this Agreement for which Buyer shall have any responsibility whatsoever.

6.14.                     Calls on Production.  Except as set forth on Schedule 6.14, Seller has not (i)  received any material advance, “take-or-pay” or other similar payments under production sales contracts that entitle the purchasers to “make up” or otherwise receive deliveries of Hydrocarbons without paying at such time the contract price therefore or (ii)  taken or received any  amount of Hydrocarbons under any gas balancing agreements or any similar arrangements not accounted for in a purchase price adjustment that permit any Person thereafter to receive any portion of the interest of Seller to “balance” any disproportionate allocation of Hydrocarbons.  Except as set forth on Schedule 6.14, no Hydrocarbons attributable to the Assets are subject to a sales contract (other than contracts terminable on no more than thirty (30) days’ notice or in accordance with rights of termination by non-operators under the applicable joint operating agreement) and no Person has any call upon, option to purchase or similar rights with respect to the production from the Assets; production from the Assets is not bound by any gas dedications

ARTICLE 8.
COVENANTS AND AGREEMENTS

8.1.                            Covenants and Agreements of Seller.  Seller covenants and agrees with Buyer as follows:

(a)                                 Operations Prior to Closing.  Except as otherwise consented to in writing by Buyer or provided in this Agreement, from the date of execution of this Agreement to the Closing Date, Seller will operate the Assets which it operates in a manner consistent in all material respects with past practice.  From the date of execution of this Agreement to the Closing Date, Seller shall pay or cause to be paid in the ordinary course of business its proportionate share of all costs and expenses incurred in connection with such operations.  Seller will notify Buyer of capital expenditures anticipated to cost in excess of two hundred and fifty thousand dollars ($250,000) per operation, net to Seller’s interest, conducted on the Assets, other than those listed on Schedule 6.7.  All costs and expenses incurred by the Parties with respect to the Capital Projects will be apportioned between the Parties as of the Effective Time, with Buyer assuming all post-Effective Time costs and expenses and Seller retaining all pre-Effective Time costs and expenses.

(b)                                 Restriction on Operations.  Subject to Section 8.1(a) and except as otherwise provided in this Section 8.1(b), unless Seller obtains the prior written consent of Buyer to act otherwise, which consent shall not be unreasonably withheld, conditioned or delayed, Seller will use commercially reasonable efforts within the constraints of the applicable operating agreements and other applicable agreements not to: (i) abandon any part of the Assets (except in the ordinary course of business, Leases that have terminated in the ordinary course of business based upon the expiration of their primary terms, or Leases that are no longer capable of production in paying quantities); (ii) except for the Capital Projects listed on Schedule 6.7 and operations consistent with the existing drilling plan attached hereto as Schedule 8.1(b), approve any operations on the Assets anticipated in any instance to cost more than $250,000 per activity, net to Seller’s interest (excepting emergency operations required under presently existing contractual obligations, ongoing commitments under existing AFEs and operations undertaken to avoid a monetary penalty or forfeiture provision of any applicable agreement or order all of which shall be deemed to be approved, provided Seller immediately notifies Buyer of any emergency operation or operation to avoid monetary penalty or forfeiture excepted herein); (iii) convey or dispose of any part of the Assets (other than replacement of equipment or sale of Hydrocarbons produced from the Assets in the ordinary course of business); (iv) enter into any Material Agreement in respect of an Asset, or materially amend or change the terms of any

(b)                                 Casualty Loss.  Prior to Closing, if a portion of the Assets is destroyed by fire or other casualty or if a portion of the Assets is taken or threatened to be taken in condemnation or under the right of eminent domain (“Casualty Loss”), Buyer shall not be obligated to purchase such Asset.  If Buyer declines to purchase such Asset, the Purchase Price shall be reduced by the Allocated Value of such Asset.  If Buyer elects to purchase such Asset, the Purchase Price shall be reduced by the estimated cost to repair such Asset (with equipment of similar utility), less all insurance proceeds which shall be payable to Buyer, up to the Allocated Value thereof (the reduction being the “Net Casualty Loss”).  Seller, at its sole option, may elect to cure such Casualty Loss and, in such event, Seller shall be entitled to all insurance proceeds.  If Seller elects to cure such Casualty Loss, Seller may replace any personal property that is the subject of a Casualty Loss with equipment of similar grade and utility, or replace any real property with real property of similar nature and kind if such property is acceptable to Buyer in its sole discretion.  If Seller elects to cure the Casualty Loss, Buyer shall purchase the affected Asset at Closing for the Allocated Value thereof.

(c)                                  Cooperation and Good Faith.  Upon the terms and subject to the conditions set forth in this Agreement, Buyer and Seller will use their respective reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Party or Parties hereto in doing, all things reasonably necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions, including using reasonable efforts to: (i) cause the conditions set forth in Article 10 to be satisfied and (ii) execute or deliver any additional instruments reasonably necessary to

33

consummate the transactions contemplated by this Agreement and to fully carry out the purposes of this Agreement; provided, however, that the foregoing provisions of this Section 8.3(c) will not require (y) any Party to perform, satisfy or discharge any obligations of any other Party under this Agreement or otherwise or (z) Seller to pay any money or other consideration or grant forbearances to any third party in order to perform, satisfy or discharge any of its obligations under this Agreement.

(d)                                 Successor Operator.  Promptly after Closing, at Buyer’s request, Seller shall send notices (in form mutually agreed to by Buyer) to co-owners, if any, of those Assets that Seller currently operates stating that Seller is resigning as operator, effective upon the Closing Date, and providing notice that Buyer shall become (or to the extent governed by an operating agreement or similar agreement, recommending that Buyer be elected) successor operator for the Assets operated by Seller.  Seller makes no representations or warranties to Buyer as to the transferability of operatorship of any Assets which Seller currently operates.  Rights and obligations associated with operatorship of the Assets may be governed by operating agreements or similar agreements and will be decided in accordance with the terms of such agreements.

If the actual amounts are not known at the time of the Final Settlement Statement, the amounts shall be re-estimated based on the best information available at the time of the Final Settlement Statement.  When the actual amounts are known, Buyer or Seller shall make such payments to the other (if any) as are necessary to effect the allocation of Taxes described in this Section 9.1.

9.4.                            Tax Cooperation.  Buyer and Seller shall cooperate fully as and to the extent reasonably requested by the other party, in connection with the filing of any Tax Returns and any audit, litigation or other proceeding (each, a “Tax Proceeding”) with respect to Taxes relating to or in connection with the Assets.  Such cooperation shall include the retention and (upon the other Party’s request) the provision of such records and information which are reasonably relevant to any such Tax Return or Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

(d)                                 Notwithstanding anything to the contrary contained in this Agreement, from and after Closing, Seller’s and Buyer’s sole and exclusive remedy against each other with respect to breaches of the representations, warranties, covenants and agreements of the Parties contained in Articles 6, 7 and 8, and the affirmations of such representations and warranties, covenants, and agreements contained in the certificates delivered by each Party at Closing pursuant to Section 12.3(b), is set forth in this Section 14.2, and if no such right of indemnification is expressly provided, then such claims are hereby waived to the fullest extent permitted by Law.  Except for the remedies contained in this Section 14.2, and any other remedies available to the Parties at law or in equity for breaches of this Agreement other than Articles 6, 7 and 8, upon Closing, each Party releases, remises, and forever discharges the other Party from any and all suits, legal or administrative proceedings, claims, demands, damages, Losses, costs, liabilities, interest, or causes of action whatsoever, in law or in equity, known or unknown, which such Parties might now or subsequently may have, based on, relating to, or arising out of this Agreement or Seller’s ownership, use, or operation of the Assets, or the condition, quality, status, or nature of the Assets, INCLUDING RIGHTS TO CONTRIBUTION OR COST RECOVERY UNDER THE COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION AND LIABILITY ACT OF 1980, AS AMENDED, BREACHES OF STATUTORY AND IMPLIED WARRANTIES, NUISANCE OR OTHER TORT ACTIONS, RIGHTS TO PUNITIVE DAMAGES, COMMON LAW RIGHTS OF CONTRIBUTION, ANY RIGHTS UNDER INSURANCE

42

POLICIES ISSUED OR UNDERWRITTEN BY THE OTHER PARTY OR ANY OF ITS AFFILIATES, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY RELEASED PERSON, INVITEE OR THIRD PERSON, AND WHETHER OR NOT CAUSED BY A PREEXISTING CONDITION.

(e)                                  EACH PARTY CONFIRMS THAT IT IS NOT RELYING ON ANY REPRESENTATION OR WARRANTY OTHER THAN THOSE EXPRESSLY SET FORTH IN THIS AGREEMENT, AND EACH PARTY ACKNOWLEDGES THAT THIS NO RELIANCE CONFIRMATION IS A MATERIAL INDUCEMENT TO THE OTHER PARTY’S WILLINGNESS TO ENTER INTO THIS AGREEMENT AND CONSUMMATE THE TRANSACTIONS CONTEMPLATED HEREBY.

14.3.                     Procedure.  The indemnifications contained in Section 14.2 shall be implemented as follows:

(a)                                 Claim Notice.  The Party seeking indemnification under the terms of this Agreement (“Indemnified Party”) shall submit a written “Claim Notice” to the other Party (“Indemnifying Party”) which, to be effective, must be delivered prior to the end of the Survival Period applicable under Section 14.4 to the representation or warranty that is the subject of such Claim Notice and must state:  (i) the amount of each payment claimed by an Indemnified Party to be owing, (ii) the basis for such claim, with supporting documentation, and (iii) a list identifying to the extent reasonably possible each separate item of Loss for which payment is so claimed.  Unless, within sixty days of receipt of a Claim Notice, the Indemnifying Party provides written notice to the Indemnified Party that it contests the Losses identified in such Claim Notice, the Indemnifying Party shall, subject to the other terms of this Section 14.3, pay to the Indemnified Party the amount of the Losses related to such indemnification claim or the uncontested portion thereof.  If the Indemnifying Party objects to a Claim Notice on the basis that it lacks sufficient information, it shall promptly request from the Indemnified Party any specific additional information reasonably necessary for it to assess such indemnification claim, and the Indemnified Party shall provide the additional information reasonably requested.  Upon receipt of such additional information, the Indemnifying Party shall notify the Indemnified Party of any withdrawal or modification of the objection.  All disputed indemnification claims shall be resolved by Buyer and Seller in accordance with either (A) a mutual agreement between Buyer and Seller, which shall be memorialized in writing, or (B) final arbitration in accordance with Section 15.13.

(b)                                 Information.  Promptly after the Indemnified Party receives notice of a claim or legal action by a third party that may result in a Loss for which indemnification may be sought under this Article 14 (a “Claim”), the Indemnified Party shall give written notice of such Claim to the Indemnifying Party.  If the Indemnifying Party or its counsel so requests, the Indemnified Party shall furnish the Indemnifying Party with copies of all pleadings and other information with respect to such Claim.  At the election of the Indemnifying Party made within sixty (60) days after receipt of such notice, the Indemnified Party shall permit the Indemnifying Party to assume control of such Claim (to the extent only that such Claim, legal action or other matter relates to a Loss for which the Indemnifying Party is liable), including the determination of all appropriate actions, the negotiation of settlements on behalf of the Indemnified Party, and

43

the conduct of litigation through attorneys of the Indemnifying Party’s choice; provided, however, that no such settlement can result in any liability or cost to the Indemnified Party for which it is entitled to be indemnified hereunder without its consent.  If the Indemnifying Party elects to assume control, (i) any expense incurred by the Indemnified Party thereafter for investigation or defense of the matter shall be borne by the Indemnified Party, and (ii) the Indemnified Party shall give all reasonable information and assistance, other than pecuniary, that the Indemnifying Party shall deem necessary to the proper defense of such Claim, legal action, or other matter.  In the absence of such an election, the Indemnified Party will use its best efforts to defend, at the Indemnifying Party’s expense, any claim, legal action or other matter to which such other Party’s indemnification under this Article 14 applies until the Indemnifying Party assumes such defense, and, if the Indemnifying Party fails to assume such defense within the time period provided above, settle the same in the Indemnified Party’s reasonable discretion at the Indemnifying Party’s expense with the Indemnifying Party’s consent which shall not be unreasonably withheld.  If such a Claim requires immediate action, both the Indemnified Party and the Indemnifying Party will cooperate in good faith to take appropriate action so as not to jeopardize defense of such Claim or either Party’s position with respect to such Claim.  If the Indemnifying Party is entitled to, and does, assume the defense of any such Claim, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof; provided, however, that notwithstanding the foregoing, the Indemnifying Party shall pay the reasonable attorneys’ fees of the Indemnified Party if the Indemnified Party’s counsel shall have advised the Indemnified Party that there is a conflict of interest that could make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party (provided that the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys and one local counsel to represent all of the Indemnified Parties subject to such Claim).

14.4.                     Survival of Warranties, Representations and Covenants.  All representations and warranties contained in Articles 6 and 7 of this Agreement shall survive the Closing and remain in full force and effect until 5:00 p.m., Denver, Colorado time, on the date that is nine (9) months after the Closing Date, at which time they shall terminate, except that those representations and warranties set forth in Sections 6.1 (Status), 6.2 (Power), 6.3 (Authorization and Enforceability) and Section 6.4 (Broker’s Fees) made by Seller, and Sections 7.1 (Organization and Standing), 7.2 (Power) and 7.3 (Authorization and Enforceability) made by Buyer (the “Fundamental Representations”), will survive indefinitely (the applicable period, being referred to herein as the “Survival Period”).  The covenants and performance obligations contained in this Agreement that contemplate performance after the Closing shall survive the Closing and shall continue until all obligations with respect thereto shall have been performed or satisfied or shall have been terminated in accordance with their terms.

14.5.                     Reservation as to Non-Parties.  Nothing herein is intended to limit or otherwise waive any recourse Buyer or Seller may have against any non-party for any obligations or liabilities that may be incurred with respect to the Assets.

14.6.                     Reductions in Losses.  The amount of any Losses for which an Indemnified Person is entitled to indemnity under this Article 14 shall be reduced by the amount of insurance proceeds realized by the Indemnified Person or its Affiliates with respect to such Losses (net of any collection costs, and excluding the proceeds of any insurance policy issued or underwritten

44

by the Indemnified Person or its insurance captive or other Affiliate), and by the amount of any net Tax benefit actually realized by Buyer as a result of the events giving rise to the Losses in question.

14.7.                     Waiver by Buyer.  Seller shall not have any obligation or liability under this Agreement or in connection with or with respect to the transactions contemplated by this Agreement for any breach, misrepresentation, or noncompliance with respect to any representation, warranty, covenant, indemnity, or obligation if such breach, misrepresentation, or noncompliance shall have been waived by Buyer.

15.5.                     Assignment.  Nether Buyer nor Seller shall assign all or any portion of its respective rights or delegate all or any portion of its respective duties hereunder without the written consent of such other party hereto.

15.6.                     Headings.  The headings of the Articles and Sections of this Agreement are for guidance and convenience of reference only and shall not limit or otherwise affect any of the terms or provisions of this Agreement.

15.8.                     Governing Law.  Except as provided in this Section 15.8, this Agreement and the transactions contemplated hereby and any arbitration or dispute resolution conducted pursuant hereto shall be construed in accordance with, and governed by, the laws of the State of Colorado, without regards to conflicts of laws principles (except to the extent that the laws of the State of North Dakota are applicable to issues relating to real property, royalty issues or oil and gas leases and interests therein).  Seller agrees that it will not, and will not permit its Affiliates to, bring or support any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against the Debt Providers in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including with respect to any dispute arising out of or relating in any way to the Debt Financing or the performance thereof, in any forum other than the United States District Court for the Southern District of New York or any court of the State of New York sitting in the Borough of Manhattan in the City of New York, and notwithstanding anything to the contrary in this Agreement, Seller, on behalf of itself and its Affiliates, hereby irrevocably and unconditionally waives any right such Party may have to a trial by jury in any such proceeding.

15.10.              Binding Effect.  This Agreement shall be binding upon, and shall inure to the benefit of, the Parties hereto, and their respective successors and assigns.  Notwithstanding anything to the contrary herein, this Agreement is not a binding agreement between the Parties hereto unless and until this Agreement is duly executed in writing by representatives of the Parties and delivered by the Parties.

15.11.              No Third-Party Beneficiaries.  Other than as set forth in this Section 15.11 and in Section 15.15, this Agreement is intended only to benefit the Parties hereto and their respective permitted successors and assigns.  Nothing in this Agreement shall entitle any Person other than Seller and Buyer to any claim, cause of action, remedy or right of any kind, except that the Debt Providers and their respective current, former or future directors, officers, general or limited partners, stockholders, members, managers, controlling persons, Affiliates, employees or

47

Representatives shall be third party beneficiaries of Section 11.2, Sections 14.2(d) and (e), Section 15.8, this Section 15.11, Section 15.13 and Section 15.15.

15.12.              No Vicarious Liability.  Buyer shall not, and shall cause the other Buyer Indemnified Parties not to, assert or threaten any claim or other method of recovery, in contract, in tort or under statute, against any Person other than Seller.  Buyer shall be liable for all attorneys’ fees and court costs arising from a breach of this Section 15.12.

15.13.              Dispute Resolution and Arbitration.  All Disputes (other than a Party’s right to seek specific performance which may be brought in any court of competent jurisdiction and as to which this Section 15.13 shall not apply) between the Parties related to this Agreement shall be resolved by arbitration, pursuant to the following procedures:

(a)                                 The parties to any arbitration pursuant to this Section 15.13 shall select an arbitrator or arbitrators as follows:

(1)                                 For arbitration of a Dispute as described in Section 4.3 with respect to Title Disputed Matter or arbitration of a Dispute as described in Section 5.4 with respect to Environmental Defects, the parties to such arbitration shall select a single, independent arbitrator within ten (10) days after written demand for such arbitration by any Party.  If the parties to such arbitration are unable to agree upon a single arbitrator, then such arbitration shall be conducted with three (3) arbitrators, selected pursuant to Section 15.13(a)(2); provided, however, any such arbitrators selected pursuant to Section 15.13(a)(2) must comply with the applicable qualifications enumerated in the last two sentences in this Section 15.13(a)(1).  For Disputes involving Title Disputed Matters pursuant to Section 4.3, any arbitrator selected shall be qualified by education, knowledge and experience with title defects affecting the types of properties which are subject to the disputed Title Defect and have a minimum of ten years experience with such types of defects and properties.  For Disputes concerning Environmental Defects, the arbitrator selected shall be qualified by education, knowledge and experience with environmental defects affecting the types of properties which are subject to the disputed Environmental Defect or Environmental Defect Amount and have a minimum of ten years experience with such types of defects and properties.

(2)                                 For arbitration of any other Dispute, each side to such arbitration shall each select a single, independent arbitrator within ten (10) days after written demand for such arbitration by any Party.  The two (2) arbitrators selected by the respective sides shall, in turn, select the third neutral and independent arbitrator.  For any Dispute concerning Section 9.4 (with respect to the preparation of Tax Returns and the payment of Taxes), each of the three (3) arbitrators shall be a tax accountant with a minimum of ten years experience with the types of Taxes in question.

(b)                                 The arbitration shall be governed by Colorado Law but the specific procedure to be followed shall be determined by the arbitrator(s).  It is the intent of the Parties that the arbitration be conducted as efficiently and inexpensively as possible, with only limited discovery as determined by the arbitrator without regard to the discovery permitted under the Colorado or Federal Rules of Civil Procedure.

48

(c)                                  The arbitration proceeding shall be held in the City and County of Denver, Colorado, and a hearing shall be held no later than sixty (60) days after submission of the matter to arbitration, and a written decision shall be rendered by the arbitrators within thirty (30) days of the hearing.

(d)                                 At the hearing, the Parties shall present such evidence and witnesses as they may choose, with or without counsel.  Adherence to formal rules of evidence shall not be required but the arbitrator shall consider any evidence and testimony that he or she determines to be relevant, in accordance with procedures that it determines to be appropriate.

(e)                                  Any award entered in the arbitration shall be made by a written opinion stating the reasons and basis for the award made.

(f)                                   The costs incurred in employing the arbitrators, including the arbitrators’ retention of any independent qualified experts, shall be borne 50% by Seller and 50% by Buyer.

(g)                                  The arbitrator’s award may be filed in any court of competent jurisdiction and may be enforced by any Party as a final judgment of such court.

15.14.              Time of the Essence.  Time is of the essence in this Agreement, and the Parties agree to work in good faith toward closing the transaction on or before the Closing Date.  If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during that notice is required to be given or action taken) shall be the next day that is a Business Day.

15.15.              Certain Agreements with Respect to Debt Providers.  Seller agrees, on behalf of itself and its Affiliates, stockholders and Representatives (collectively, the “Seller Related Parties”) that the Debt Providers and their Affiliates, stockholders and representatives and each of their successors and assigns (i) shall be subject to no liability or claims by the Seller Related Parties arising out of or relating to this Agreement, the financing or the transactions contemplated hereby or in connection with the Debt Financing, or the performance of services by such Debt Providers or their Affiliates or representatives with respect to the foregoing and (ii) are express third party beneficiaries of this Section 15.15, (which may not be changed as to any type of Debt Financing without its prior written consent) and Section 11.2, Sections 14.2(d) and (e), Section 15.8, Section 15.11 and Section 15.13.

15.16.              Parent Assurances and Representations.

(a)                                 Parent shall cause Buyer to comply in full and promptly with any specific performance order issued by a court of competent jurisdiction that requires Buyer to close the transactions contemplated hereby on the terms set forth herein. Parent waives all defenses and rights of subrogation with respect to its unconditional assurance in this Section 15.16(a).

49

(b)                                 Representations and Warranties of Parent.

(1)                                 Parent is a corporation duly organized, validly existing and in good standing under the laws of the Yukon Territory.

(2)                                 Parent has all requisite power and authority to carry on its business as presently conducted.  The execution and delivery of this Agreement and the fulfillment of and compliance with the terms and conditions hereof (including the guarantee contemplated by this Section 15.16) will not, as of the Closing, violate or conflict with, any material provision of Parent’s governing documents, or, to the knowledge of Parent, any judgment, decree, order, statute, rule or regulation applicable to Parent.

(3)                                 Assuming the due authorization, execution and delivery by Seller, this Agreement constitutes Parent’s legal, valid and binding obligation enforceable in accordance with its terms, subject, however, to the effects of bankruptcy, insolvency, reorganization, moratorium and other laws for the protection of creditors, as well as to general principles of equity, regardless of whether such enforceability is considered in a proceeding in equity or at law.
