3.3. Allocation of the Purchase Price. Buyer, with Seller’s approval, has allocated a portion of the Purchase Price among the ▇▇▇▇▇, Leases Within Drillsite Spacing Units, and Leases Outside of Drillsite Spacing Units as set forth on Exhibit B.

The value so allocated to a particular Asset may be referred to as the “Allocated Value” for that Asset.

(a) Settlement Statements. The Purchase Price shall be adjusted at Closing pursuant to a “Preliminary Settlement Statement” prepared by Seller, submitted to Buyer at least five business days prior to Closing for Buyer’s comment and review and agreed to by both Buyer and Seller. Buyer and Seller shall use commercially reasonable efforts to agree on the Preliminary Settlement Statement. The Parties shall negotiate in good faith in an effort to agree on the Preliminary Settlement Statement. The Preliminary Settlement Statement shall set forth the Closing Amount and all adjustments to the Purchase Price and associated calculations. The term “Closing Amount” means the Purchase Price, adjusted as provided in this Section using reasonable estimates if actual numbers are not available. After Closing, the Purchase Price shall be adjusted pursuant to the Settlement Statement delivered pursuant to Section 14.1.

(b) Property Expenses. For the purposes of this Agreement, the term “Property Expenses” shall mean, all costs attributable to the ownership, maintenance, perpetuation and operation of the Assets, including without limitation, all capital and operating expenses, joint interest ▇▇▇▇▇▇▇▇, lease operating expenses, lease rental and maintenance costs, royalties, overriding royalties, leasehold payments, Taxes (as defined and apportioned as of the Effective Date), drilling, completing and equipping expenses, workover expenses, geological, geophysical, other exploration or development expenditures, in each case to the extent chargeable to owners of the Assets under the Samson Operating Agreement and any other applicable joint operating agreement, as all of the foregoing are affected by the Farmout Agreements. The Property Expenses exclude all liabilities, losses, costs, and expenses attributable to:

(1) claims, investigations, administrative proceedings, arbitration or litigation directly or indirectly arising out of or resulting from actual or claimed personal injury, illness or death; property damage; environmental damage or contamination; other torts; private rights of action given under any Law; or violation of any Law to the extent that such matters are based on events occurring prior to the Closing Date;

(6) gas balancing and other production balancing obligations to the extent that the obligation arose prior to the Effective Date;

(7) casualty and condemnation to the extent that the events arose prior to the Effective Date; and

(8) any claims for indemnification, contribution or reimbursement from any third Person with respect to liabilities, losses, costs and expenses of the type described in preceding clauses (1) through (7), whether such claims are made pursuant to contract or otherwise;

provided however, that any environmental liabilities shall be governed by Article 6 and in the event of a conflict between Section 3.4(b) and Article 6, Article 6 shall govern in all respects.

For the avoidance of doubt, for all purposes of this Agreement, Property Expenses (i) shall be considered and deemed “attributable to the period prior to the Effective Date” if the work that is the basis of the expenses was performed in the field prior to the Effective Date and (ii) shall be considered and deemed “attributable to the period after the Effective Date” if the work that is the basis of the expenses was performed in the field after the Effective Date.

(1) An amount equal to all proceeds (net of royalty and Taxes not otherwise accounted for hereunder) received by Buyer from the sale of all Hydrocarbons produced from or credited to the Assets prior to the Effective Date;

(2) Subject to Section 9.1(a), an amount equal to the Property Expenses, incurred and paid by Seller, that are attributable to the period after the Effective Date;

(3) To the extent not covered in the preceding paragraph, an amount equal to the prepaid Property Expenses attributable to the period after the Effective Date that were paid by or on behalf of Seller;

(4) An amount equal to the value (net of applicable Taxes and deductions by the purchaser(s) of production) of Seller’s share of all oil in storage tanks with respect to the Assets at the Effective Date to be calculated as follows: The value shall be the product of (i) the volume in each storage tank (attributable to Seller’s interest) as of the Effective Date as shown by the actual gauging reports, less any volumes below the load line, multiplied by (ii) the price actually received for February 2012 production under the applicable marketing contract if the hydrocarbons in question had been sold; provided, however, that the adjustment contemplated by this subsection (4) shall be made only to the extent that Seller does not receive and retain the proceeds, or portion thereof, attributable to the pre-Effective Date merchantable oil in the storage tanks;

(5) Subject to Section 9.1(a), as applicable, an amount equal to the Seller’s actual cost paid by Seller as of Closing Date for Post-Effective Date AMI Leases; and

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

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

(1) Proceeds received and retained by Seller (net of applicable Taxes not otherwise accounted for hereunder and royalties) that are attributable to production from the Assets after the Effective Date;

(2) The amount of the Property Expenses, that remain unpaid by Seller, or that have been paid by Buyer, that are attributable to the period prior to the Effective Date;

(3) An amount equal to the sum of all Environmental Defect Adjustments;

(4) An amount equal to the Title Defect Adjustments; and

5.1. Title and Definitions.

(a) Title. Subject to the Title Threshold set forth in Section 5.2(b), Seller represents and warrants to Buyer that as of the Closing Date in respect to the ▇▇▇▇▇ and Leases, Seller owns Defensible Title, as defined in Section 5.1(b).

(2) as to the Leases, Leases Within Drillsite Spacing Units and Leases Outside Drillsite Spacing Units, excluding Post-Effective Date AMI Leases, means such title subject to and except for Permitted Encumbrances that entitles Seller to receive ownership and control of the Leases equal to the Net Mineral Acres for each Lease set forth on Exhibit A and that is free and clear of encumbrances, liens and defects.

(1) lessors’ royalties, overriding royalties, net profits interests, production payments, reversionary interests and similar burdens (payable or in suspense) if the net cumulative effect of such burden does not operate to reduce the NRI below the amount set forth on Exhibit B as to the ▇▇▇▇▇; and with respect to the Leases, does not operate to reduce the Net Mineral Acres on a Lease to an amount less than the Net Mineral Acres of Seller in the Lease, as set forth on Exhibit A;

(2) liens for Taxes, or assessments not yet due or delinquent or, if delinquent, 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 federal, state, local or foreign governmental bodies, in connection with the conveyance of the applicable Asset if the same are customarily obtained after such conveyance;

(5) easements, rights-of-way, servitudes, permits, surface leases and other rights with respect to surface operations, 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 as has been conducted in the past or materially affect the value thereof;

(6) materialmen’s, mechanics’, operators’ or other similar liens arising in the ordinary course of business incidental to operation of the Assets (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, obligations under 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;

(7) the terms of the Samson Operating Agreement;

(8) liens or encumbrances that proportionately burden the interest of Seller and Buyer (and/or Buyer’s affiliates), not created by Seller, including, but not limited to, mortgages or deeds of trust burdening a Lease and granted by a mineral owner or its predecessor that have not been subordinated to the Lease;

(9) a failure by Seller to have received an assignment of a Lease from Samson, as the “Acquiring Party”, under or pursuant to the AMI Clause, when Seller has as the “Receiving Party” made a timely election under the AMI Clause to participate in the Lease acquisition and Seller can provide Buyer evidence of its timely election to participate in the lease acquisition, provided such Leases are disclosed on Exhibit P;

(10) the existence of prior unreleased oil and gas leases having primary terms that have expired and for which no affidavit of production appears of record; and

(11) missing probate or estate proceedings for mineral owners when affidavits of heirship confirming succession of interest are in the title materials or title reports of the acquiring party;

(12) an election (whether affirmative or not) by a third party subject to the Samson Operating Agreement or other applicable joint operating agreement whereby such third party is deemed to have not participated in a proposed operation, provided that this shall be a Permitted Encumbrance for only the term of the recoupment period associated with such non-consent election; and

(13) state laws and regulations, and the rules and regulations of the North Dakota Industrial Commission with respect to pooling and unitization, including the statutory non-consent penalty.

(d) Title Defect.

(1) The term “Title Defect” as to ▇▇▇▇▇, means any lien, encumbrance, claim, defect in or objection to real property title, excluding Permitted Encumbrances, that alone or in combination with other defects renders the Seller’s title to any Well less than Defensible Title and reduces the Allocated Value of the affected Well.

(2) The term “Title Defect” as to Leases Within Drillsite Spacing Units means with respect to the Leases any valid objection to Seller’s real property title, excluding Permitted Encumbrances, causing the ownership of Seller in the Leases Within Drillsite Spacing Units as of the Closing Date to be less than 17,744.23 Net Mineral Acres (less any Net Mineral Acres associated with Leases which expired on their own terms after the Effective Date and prior to Closing in the ordinary course of business and not due to a default by Seller (the “Customary Expired Leases”)). The term “Title Defect” as to Leases Outside of Drillsite Spacing Units means with respect to the Leases any valid objection to Seller’s real property title, excluding Permitted Encumbrances, causing the ownership of Seller in the Leases Outside of Drillsite Spacing Units as of the Closing Date to be less than 32,668.83 Net Mineral Acres (less any Net Mineral Acres associated with the Customary Expired Leases). For all purposes of Article 5, including this Section 5.1(d)(2), Section 5.1(f)(1) and Section 5.1(f)(2), the references to “17,744.23 Net Mineral Acres” and “32,668.83 Net Mineral Acres” shall not include any Net Mineral Acres associated with the Post-Effective Date AMI Leases, which Leases shall be subject to the provisions of Section 9.1(a)(3).

(e) Title Defect Value for ▇▇▇▇▇. “Title Defect Value” means for ▇▇▇▇▇ the amount by which the Allocated Value of given Well has been reduced on account of the Title Defect. In determining the Title Defect Value, the Parties intend to include only that portion of the Asset affected by the defect. The Title Defect Value may not exceed the Allocated Value of the Well and shall be determined by the Parties in good faith taking into account all relevant factors, including without limitation, the following:

(1) If the Title Defect is a lien or encumbrance on the Asset, the Title Defect Value shall be the cost of removing such lien or encumbrance.

(2) If the Title Defect is an actual reduction in NRI in a Well without a proportionate change in the WI, the Title Defect Value shall be the Allocated Value for the particular Asset, proportionately reduced by the ratio of the actual NRI to the represented NRI.

(3) If the Title Defect does not fall into subsection (1) or (2), then the Title Defect Value shall be determined by the Parties in good faith, taking into account all relevant factors, including without limitation, the following:

(i) The Allocated Value of any affected Well;

(ii) If such Well is producing, the present value of the future income expected to be produced therefrom; and

(iii) The legal effect of the Title Defect.

(f) Title Defect Value for Leases. “Title Defect Value” shall mean for Leases:

(1) If the Title Defect is based on Seller not owning as of the Closing Date at least 17,744.23 Net Mineral Acres of Leases Within Drillsite Spacing Units (less any Net Mineral Acres associated with the Customary Expired Leases), then the Defect Value shall be the amount of any such deficiency in Net Mineral Acres multiplied by a value per Net Mineral Acre for Leases Within Drillsite Spacing Units set forth on Exhibit B. For example, if Buyer determines that Seller has only 17,644.23 Net Mineral Acres under Leases Within Drillsite Spacing Units (less any Net Mineral Acres associated with the Customary Expired Leases), then the Title Defect Value for such deficiency shall be 100.00 Net Minerals Acres times the Allocated Value per Net Mineral Acre for Leases Within Drillsite Spacing Unit as set forth on Exhibit B.

(2) If the Title Defect is based on Seller not owning as of the Closing Date at least 32,668.83 Net Mineral Acres of Leases Outside of Drillsite Spacing Units (less any Net Mineral Acres associated with the Customary Expired Leases), then the Defect Value shall be the amount of any such deficiency in Net Mineral Acres multiplied by a value per Net Mineral Acre for Leases Outside of Drillsite Spacing Units set forth on Exhibit B. For example, Buyer determines that Seller has only 32,468.83 Net Mineral Acres under Leases Outside of Drillsite Spacing Units (less any Net Mineral Acres associated with the Customary Expired Leases), then the Title Defect Value for such deficiency shall be 200.00 Net Minerals Acres times the Allocated Value per Net Mineral Acre for Leases Outside of Drillsite Spacing Unit as set forth on Exhibit B.

5.2. Purchase Price Adjustments for Title Defects.

(a) Notice of Title Defects. Buyer shall give Seller each written “Notice of Title Defects” as soon as possible but no later than 5:00 p.m. Mountain Time on May 17, 2012 (the “Title Defect Date”). Each such notice must be in writing and (i) name the affected Asset; (ii) describe each Title Defect with respect to the affected Asset; (iii) describe the basis for each Title Defect set forth in such notice; (iv) attach Supporting Documentation not in Seller’s possession; (v) state the Allocated Value (if any) of the affected Asset; (vi) state Buyer’s good faith estimate of the Title Defect Value; and (vii) set forth the computations, upon which Buyer’s estimate is based. For the purposes of this Section, “Supporting Documentation” for a particular Title Defect means if the basis is derived from any document, a copy of such document (or pertinent part thereof) or if the basis is derived from any gap in Seller’s chain of title, the documents preceding and following the gap shall be attached, or in any other case reasonable written documentation. If such Supporting Documentation is not in Seller’s possession, Buyer agrees to provide a copy of such documentation to Seller, or alternatively, a location where Seller can obtain such supporting documentation – such as a file number, etc.

(b) Defect Adjustments. If an Asset is affected by a Title Defect, the Purchase Price will be reduced under Section 3.4 and as set forth below, unless, (i) Seller cures the Title Defect prior to Closing; (ii) Buyer agrees to waive the relevant Title Defect; (iii) Seller, with Buyer’s consent, which Buyer may withhold in its sole discretion, elects on or before Closing to indemnify Buyer against any loss attributable to the relevant Title Defect; or (iv) the Title Threshold has not been exceeded. The Purchase Price shall be adjusted for Title Defects only if the aggregate amount of all Title Defect Values for all of the Assets exceeds 1% of the Purchase Price (the “Title Threshold”) (with the amount of such adjustment being the “Title Defect Adjustment”). The Title Threshold is a threshold and not a deductible. The Title Threshold and the Environmental Threshold are separate and distinct and shall operate independently. The Title Threshold shall be considered one threshold for all purposes under this Agreement, whether Buyer submits a Title Defect pre-Closing pursuant to Section 5.2 or a claim for indemnification pursuant to Article 15, and accordingly, each Title Defect Value associated with each Title Defect submitted pursuant to Section 5.2 shall count toward the Title Threshold both before and after Closing.

5.3. Title Benefit. If Seller determines that (a) the ownership of any Well entitles Seller to a larger NRI or reduces royalty and other burdens on production with respect to such Well so that the Seller’s ownership in the Well is greater than that set forth on Exhibit B; or (b) the ownership of any Lease entitles Seller to a greater number of Net Mineral Acres than that set forth on Exhibit A; (a “Title Benefit”), then Seller shall notify Buyer of such Title Benefit in writing on or before the Title Defect Date, describing in such notice the same items which are provided in a Notice of Title Defects pursuant to Section 5.2. The amount of each Title Benefit shall be determined in the same manner as provided in Section 5.1(e) and 5.1(f), as applicable, with respect to Title Defect Values. The aggregate amount of the Title Benefits will only be used to reduce the aggregate amount of the Title Defect Values and the Title Defect Adjustment.

5.4. Procedures for Title Defects .

(a) If Seller and Buyer agree that a Title Defect exists and if prior to the Closing Date (or if following the Closing Date with respect to Title Defects asserted post-Closing pursuant to a claim for indemnification due to a breach of the representation in Section 5.1(a)), Seller has been unable or is unwilling to cure such Title Defect (and there is no dispute as to whether or not it has been cured), then (i) subject to the Title Threshold under Section 5.2(b), Buyer may elect not to acquire the Asset subject to the Title Defect, such asset being referred to herein as the “Title Defect Property”, and the Closing Amount will be reduced by the Allocated Value of such Title Defect Property (or if no Allocated Value, then the Allocated Value derived from the associated Asset with an Allocated Value), or (ii) subject to the Title Threshold under Section 5.2(b), Buyer may elect to acquire such Title Defect Property from Seller and the Closing Amount will be reduced by the Title Defect Amount with respect to such Title Defect Property (taking into account the results of any curative efforts made by or on behalf of Seller with respect to such Title Defect Property).

(b) If Seller and Buyer are unable to reach an agreement at any time as to whether a Title Defect exists or, if Buyer and Seller agree that a Title Defect exists but disagree as to whether it has been cured or the amount of the Title Defect Amount attributable to such Title Defect, then dispute resolution procedures may be initiated by Seller or Buyer under Section 5.5 promptly following the inability to reach an agreement.

(c) Subject to Section 5.5, any Asset for which Buyer and Seller are unable to reach an agreement at any time as to whether a Title Defect exists or, if Buyer and Seller agree that a Title Defect exists but disagree as to whether it has been cured or the amount of the Title Defect Amount attributable to such Title Defect, may be retained by Seller and the Closing Amount shall be reduced by the Allocated Value therefor (or, if no Allocated Value then the Allocated Value derived from the associated Asset with an Allocated Value).

(d) If Buyer submits a Title Defect pre-Closing pursuant to either Section 5.2 or post-Closing pursuant to a claim for indemnification pursuant to Article 15, the procedures set forth in this Section 5.4 and in Section 5.3 shall be applicable thereto, and for purposes of those provisions, the Title Defect Date shall be June 30, 2012.

5.5. Arbitration.

(a) If any Party hereto elects to submit any dispute to arbitration as specifically provided in this Section 5.5, then such Party will notify the other Party in writing. Within fifteen (15) days following such notice, Seller and Buyer agree to jointly select an arbitrator. For disputes regarding Title Defects or Title Defect Amounts, the arbitrator will be an experienced oil and gas attorney, familiar by training and experience with U.S. oil and gas legal and business matters including titles and oil and gas transactions. This person will be the sole arbitrator (the “Title Defect Arbitrator”) to hear and decide all existing disputes regarding asserted Title Defects and Title Defect Amounts. If Seller and Buyer are unable to agree on the Title Defect Arbitrator within the fifteen (15)-day period, either Party hereto may apply to a Colorado court regarding asserted Title Defects and Title Defect Amounts for the selection of a Title Defect Arbitrator with the qualifications set forth in this Section.

(b) Any arbitration hearing, if one is desired by the Title Defect Arbitrator, will be held in Denver, Colorado, or such other location acceptable to both Parties and the Title Defect Arbitrator. Seller or Buyer may elect to conduct the proceeding by written submissions from Seller and Buyer with exhibits, including interrogatories, supplemented with appearances by Buyer and Seller as the Title Defect Arbitrator may desire. The arbitration proceeding, subject only to the terms hereof, will be conducted informally and expeditiously and in such a manner as to result in a good faith resolution as soon as reasonably possible under the circumstances. The decision of the Title Defect Arbitrator with respect to such remaining disputed matters will be reduced to writing and binding on the Parties. Judgment upon the award(s) rendered by the Title Defect Arbitrator may be entered and execution had in any court of competent jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement. Seller and Buyer, respectively, will bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the Title Defect Arbitrator will be shared equally by the Parties.

(c) The arbitration will commence as soon as possible after the Title Defect Arbitrator is selected in accordance with the provisions of this Section 5.5. In fulfilling his or her duties with respect to determining the amount of a Title Defect Amount, the Title Defect Arbitrator shall consider the terms and provisions of this Agreement, and may consider such matters as, in the opinion of the Title Defect Arbitrator, are necessary or helpful to make a proper valuation. Furthermore, the Title Defect Arbitrator may consult with and engage disinterested third parties to advise the Title Defect Arbitrator including, without limitation, title and oil and gas lawyers, accountants and consultants, and the fees and expenses of such third parties will be considered to be charges and expenses of the Title Defect Arbitrator. The sole remedy in any arbitration award will be resolution of alleged Title Defects and Title Defect Amounts and the Title Defect Arbitrator will not award any other remedy, including, without limitation, equitable relief, actual damages, consequential, exemplary or punitive damages, attorneys’ fees or interest reflecting the time value of money.

(d) Any replacement Title Defect Arbitrator, should one become necessary, will be selected in accordance with the procedure provided above for the initial selection of the Title Defect Arbitrator.

(e) As to any determination of amounts owing under the terms of this Section 5.5, no lawsuit based on such claimed amounts owing will be instituted by either Buyer or Seller, other than to compel arbitration proceedings or enforce the award of the Title Defect Arbitrator.

(f) All privileges under state and federal law, including attorney-client and work-product privileges, will be preserved and protected to the same extent that such privileges would be protected in a federal or state court proceeding applying state or federal law, as the case may be.

5.6. Casualty Loss. Prior to Closing, if a portion of the Assets is destroyed by fire or other casualty, or is taken or threatened to be taken in condemnation or under the right of eminent domain (with such event being a “Casualty Loss”), Buyer shall purchase the Asset at Closing for the Allocated Value of the Asset reduced by the estimated cost to repair or replace such Asset (with equipment of similar utility) up to the Allocated Value thereof. Seller, at its sole option, may elect to cure such Casualty Loss. 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. If Seller cures the Casualty Loss, Buyer shall purchase the affected Asset at Closing for the Allocated Value thereof without any Purchase Price Adjustment for such Casualty Loss.

(a) Retained Environmental Liabilities. Upon Closing, subject to Section 6.4, Seller agrees to retain and pay, perform, fulfill and discharge all claims, cost, expenses, liabilities and obligations accruing or relating to and release Buyer (but no other third parties) from all Losses attributable to and relating to (i) Environmental Defects for which Seller receives a valid and timely Environmental Defect Notice, and (ii) the disposal prior to the Closing Date of any Hazardous Materials generated on, by or from the Assets and disposed off of the Assets in violation of Environmental Laws (collectively, the “Retained Environmental Liabilities”); provided that timely receipt of a valid Environmental Defect Notice and verification of the costs of Remediation by the Environmental Consultant are conditions precedent to Seller’s obligation to retain liability for any Environmental Defect under Section 6.3(a)(i). If Seller receives an Environmental Defect Notice for a particular Environmental Defect and such Environmental Defect Notice is not contested under the provisions of Section 6.5, and subject to the provisions of Section 6.4, Seller agrees to retain all claims, costs, expenses, liabilities and obligations accruing or relating to the Environmental Defect that was the subject of the Environmental Defect Notice.

(b) Assumed Environmental Liabilities. Except for Retained Environmental Liabilities and except for Losses arising out of or relating to Seller’s breach of its representation and warranties, and subject to the provisions of Section 6.4, upon Closing, Buyer agrees to assume and pay, perform, fulfill and discharge and release Seller from all Losses relating to environmental conditions in, on or under the Assets attributable to the period of time before and after the Closing Date, including without limitation any and all liability for (i) Naturally Occurring Radioactive Materials as defined by the Environmental Laws, (ii) man-made material fibers, (iii) the obligation to plug and abandon the ▇▇▇▇▇ listed on Exhibit B, and (iv) reclamation of existing well sites on the Lands (collectively, the “Assumed Environmental Liabilities”).

(c) Failure to Deliver Environmental Defect Notice. If Buyer fails to timely deliver an Environmental Defect Notice with respect to an Asset, or if the aggregate of all Environmental Defects is equal to or less than the Environmental Threshold, Buyer shall be deemed to (i) accept the environmental condition(s) in, on and under that Asset, (ii) have waived its right to claim an Environmental Defect with respect to that particular condition in, on or under the Asset, and (iii) include the particular environmental condition(s) as part of the Assumed Environmental Liabilities; provided that, notwithstanding the foregoing, Buyer may elect unilaterally to exclude any Well which has an Environmental Defect from the Transaction in accordance with the procedure set forth in Section 6.4(b) and the environmental conditions with respect to such Asset shall be part of the Retained Environmental Liabilities.

6.4. Remedies.

(a) Environmental Defects less than the Environmental Threshold. If the aggregate Environmental Defect Values of all valid Environmental Defect Notices timely delivered to Seller is less than or equals 1% of the Purchase Price, net to Seller’s interest (with such amount being the “Environmental Threshold”), the Environmental Defects identified in such notices, other than Environmental Defects associated with any Well excluded by Buyer under Section 6.3(c), will not be Retained Environmental Liabilities; accordingly, Seller will have no obligation hereunder with respect thereto and Buyer agrees to assume, and release Seller from, the obligations with respect thereto as part of the Assumed Environmental Liabilities, other than as related to breaches of Seller’s representations and warranties in Section 6.2. For the avoidance of doubt, this provision shall not limit Buyer’s remedies in Article 15 for breaches of Seller’s representations and warranties in Section 6.2. The Environmental Threshold referenced in the preceding sentence is a threshold and not a deductible. The Environmental Threshold and the Title Threshold are separate and distinct and operate independently.

(b) Environmental Defects greater than the Environmental Threshold. If the aggregate Environmental Defect Values of all Environmental Defect Notices timely delivered to Seller exceeds the Environmental Threshold, Seller shall elect one of the following options: (i) remediate the condition on the affected Assets comprising the specified Environmental Defect(s) as promptly as practicable (and retain its obligation to indemnify and defend Buyer from any Losses relating to such Environmental Defects), such remediation to be to Buyer’s reasonable satisfaction and consistent with Environmental Laws; or (ii) pay Buyer no later than 10 days following the delivery of the applicable Environmental Defect Notice(s) Buyer’s estimate of the Environmental Defect Value (“Environmental Defect Adjustment”), in which event Buyer shall release Seller from any further Retained Environmental Liability relating to the Environmental Defects so satisfied. Notwithstanding the foregoing, if the aggregate Environmental Defect Value claimed by Buyer for a particular Asset affected by an Environmental Defect (as agreed to by the Parties or established pursuant to Section 6.5) exceeds the Environmental Threshold, in addition to the options set forth in this Section, Seller or Buyer may elect unilaterally by written notice to the other party to exclude the Asset from this Transaction, in which event (a) if such election is made prior to Closing, Seller shall retain such Asset and the Purchase Price shall be reduced by the Allocated Value of such Asset, and (b) if such election is made after Closing, Buyer will reconvey the Asset to Seller effective as of the Effective Date and Seller will refund the Allocated Value paid with respect thereto, and Buyer will refund to Seller the proceeds of production it has received from such Asset, net of any Property Expenses borne by Buyer with respect to such Asset.

6.5. Contested Environmental Defects. If Seller contests the existence of an Environmental Defect or the Environmental Defect Value, Seller shall notify Buyer in writing on or before 30 days after receipt of the Environmental Defect Notice (“Rejection Notice”). The Rejection Notice shall state with reasonable specificity the basis of the rejection of the Environmental Defect or the Environmental Defect Value. Within 5 business days after receipt of the Rejection Notice, representatives of Buyer and Seller knowledgeable in environmental matters shall meet and, either (i) mutually agree to reject the particular Environmental Defect or (ii) agree on the validity of such Environmental Defect and the Environmental Defect Value. If the Parties cannot agree on either options (i) or (ii) in the preceding sentence, the Environmental Defect and/or the Environmental Defect Value subject to the Rejection Notice shall be resolved in accordance with the arbitration procedures set forth in Section 6.7. If Seller fails to timely deliver a Rejection Notice, Seller shall be deemed to have accepted the validity of the Environmental Defect and Buyer’s estimate of the Environmental Defect Value, and shall be deemed to have waived its own option to contest the Environmental Defect pursuant to this Section.

6.6. Procedures Regarding Environmental Defects.

(a) If Seller and Buyer agree that an Environmental Defect exists and if prior to the Closing Date, Seller has been unable or is unwilling to cure such Environmental Defect (and there is no dispute as to whether or not it has been cured), then (i) Buyer may elect not to acquire the Asset subject to the Environmental Defect, such asset being referred to herein as the “Environmental Defect Property”, and if the Environmental Threshold has been exceeded, the Closing Amount will be reduced by the Allocated Value of such Environmental Defect Property (or if no Allocated Value, then the Allocated Value derived from the associated Asset with an Allocated Value), or (ii) Buyer may elect to acquire such Environmental Defect Property from Seller and the Closing Amount will be reduced by the Environmental Defect Value with respect to such Environmental Defect Property if the Environmental Threshold has been exceeded (taking into account the results of any curative efforts made by or on behalf of Seller with respect to such Environmental Defect Property).

(b) If Seller and Buyer are unable to reach an agreement at any time as to whether an Environmental Defect exists or, if Buyer and Seller agree that an Environmental Defect exists but disagree as to whether it has been cured or the amount of the Environmental Defect Value attributable to such Environmental Defect, then dispute resolution procedures may be initiated by Seller or Buyer under Section 6.7 promptly following the inability to reach an agreement.

(c) Subject to Section 6.7, any Asset for which Buyer and Seller are unable to reach an agreement at any time as to whether an Environmental Defect exists or, if Buyer and Seller agree that an Environmental Defect exists but disagree as to whether it has been cured or the amount of the Environmental Defect Value attributable to such Environmental Defect, may be retained by Seller and the Closing Amount shall be reduced by the Allocated Value therefor (or, if no Allocated Value then the Allocated Value derived from the associated Asset with an Allocated Value).

6.7. Arbitration.

(a) If either Party hereto elects to submit any dispute to arbitration as specifically provided in this Section 6.7, then such Party will notify the other Party in writing. Within fifteen (15) days following such notice, Seller and Buyer agree to jointly select an arbitrator. For disputes regarding Environmental Defects or Environmental Defect Values, the arbitrator will be an experienced environmental attorney, familiar by training and experience with environmental legal and business matters including environmental matters in connection with oil and gas transactions. This person will be the sole arbitrator (the “Environmental Defect Arbitrator”) to hear and decide all existing disputes regarding asserted Environmental Defects and Environmental Defect Values. If Seller and Buyer are unable to agree on the Environmental Defect Arbitrator within the fifteen (15)-day period, either Party hereto may apply to a Colorado court regarding asserted Environmental Defects and Environmental Defect Values for the selection of an Environmental Defect Arbitrator with the qualifications set forth in this Section.

(b) Any arbitration hearing, if one is desired by the Environmental Defect Arbitrator, will be held in Denver, Colorado, or such other location acceptable to both Parties and the Environmental Defect Arbitrator. Seller or Buyer may elect to conduct the proceeding by written submissions from Seller and Buyer with exhibits, including interrogatories, supplemented with appearances by Buyer and Seller as the Environmental Defect Arbitrator may desire. The arbitration proceeding, subject only to the terms hereof, will be conducted informally and expeditiously and in such a manner as to result in a good faith resolution as soon as reasonably possible under the circumstances. The decision of the Environmental Defect Arbitrator with respect to such remaining disputed matters will be reduced to writing and binding on the Parties. Judgment upon the award(s) rendered by the Environmental Defect Arbitrator may be entered and execution had in any court of competent jurisdiction, or application may be made to such court for a judicial acceptance of the award and an order of enforcement. Seller and Buyer, respectively, will bear their own legal fees and other costs incurred in presenting their respective cases. The charges and expenses of the Environmental Defect Arbitrator will be shared equally by the Parties.

(c) The arbitration will commence as soon as possible after the Environmental Defect Arbitrator is selected in accordance with the provisions of this Section 6.7. In fulfilling his or her duties with respect to determining the amount of an Environmental Defect Value, the Environmental Defect Arbitrator shall consider the terms and provisions of this Agreement, and may consider such matters as, in the opinion of the Environmental Defect Arbitrator, are necessary or helpful to make a proper valuation. Furthermore, the Environmental Defect Arbitrator may consult with and engage disinterested third parties to advise the Environmental Defect Arbitrator including, without limitation, environmental and oil and gas lawyers, accountants and consultants, and the fees and expenses of such third parties will be considered to be charges and expenses of the Environmental Defect Arbitrator. The sole remedy in any arbitration award will be resolution of alleged Environmental Defects and Environmental Defect Values and the Environmental Defect Arbitrator will not award any other remedy, including, without limitation, equitable relief, actual damages, consequential, exemplary or punitive damages, attorneys’ fees or interest reflecting the time value of money.

(d) Any replacement Environmental Defect Arbitrator, should one become necessary, will be selected in accordance with the procedure provided above for the initial selection of the Environmental Defect Arbitrator.

(e) As to any determination of amounts owing under the terms of this Section 6.7, no lawsuit based on such claimed amounts owing will be instituted by either Buyer or Seller, other than to compel arbitration proceedings or enforce the award of the Environmental Defect Arbitrator.

6.8. Buyer’s Exclusion Right. In addition to the rights and remedies otherwise granted to Buyer in this Article and subject to 12.1(a), Buyer shall have the right to unilaterally exclude any Asset from the Transaction that has an Environmental Defect caused by PCBs, so long as Buyer delivers to Seller, on or before 5:00 p.m. Mountain Time on May 17, 2012, an Environmental Defect Notice which details the PCB contamination and that Buyer elects to exclude such Asset from the Transaction pursuant to this Section 6.8.

6.9. Exclusive Remedies. The rights and remedies granted each Party in this Article, together with the indemnifications set forth in Article 15 and the rights of each Party to not close pursuant to Article 11, are the exclusive rights and remedies against the other Party related to any Environmental Defect or other environmental matters.

Seller (a) to its knowledge as a non-operator, has obtained and is maintaining all Governmental Authorizations that are presently necessary or required for the ownership and operation of the Assets as currently owned by Seller and (b) to its knowledge as a non-operator has operated the Assets in all respects in accordance with the conditions and provisions of such Governmental Authorizations, and no written notices of any 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.

(b) Buyer has all requisite power and authority to own the Assets after Closing, to carry on its business as presently conducted, to execute, deliver, and perform this Agreement and each other agreement, instrument, or document executed or to be executed by Buyer in connection with the Transaction to which it is a party and to consummate this Transaction. The execution, delivery, and performance by Buyer of this Agreement and each other agreement, instrument, or document executed or to be executed by Buyer in connection with the Transaction to which it is a party, and the consummation by it of the Transaction and thereby, have been duly authorized by all necessary corporate action of Buyer.

(c) The execution and delivery of this Agreement does not, and the fulfillment of and compliance with the terms and conditions hereof will not, as of Closing, (i) violate, or be in conflict with, any provision of Buyer’s governing documents, or any provision of any statute, rule or regulation applicable to Buyer or any material lease, contract, agreement, instrument or obligation to which Buyer is a party or by which Buyer is bound, or (ii) violate, or be in conflict with any judgment, decree or order applicable to Buyer.

8.2. Authorization and Enforceability. The execution, delivery and performance of this Agreement and this Transaction have been duly and validly authorized by all requisite action on behalf of Buyer. This Agreement and each other agreement, instrument, or document executed or to be executed by Buyer in connection with this Transaction to which it is a party constitutes, or when executed and delivered will constitute, Buyer’s legal, valid and binding obligation, enforceable in accordance with their respective terms, subject, however, to the effects of bankruptcy, insolvency, reorganization, moratorium and similar laws for the protection of creditors and equitable principles which may limit the availability of certain equitable remedies (such as specific performance) in certain instances.

8.3. Liability for Brokers’ Fees. Buyer has not incurred any liability, contingent or otherwise, for brokers’ or finders’ fees relating to this Transaction for which Seller shall have any responsibility whatsoever.

8.4. Litigation.

8.5. Securities Laws, Access to Data and Information. Buyer is familiar with the Assets and it is a knowledgeable, experienced and sophisticated investor in the oil and gas business. Buyer understands and accepts the risks and absence of liquidity inherent in ownership of the Assets. Buyer acknowledges that the Assets are or may be deemed to be “securities” under the Securities Act of 1933, as amended, and certain applicable state securities or Blue Sky laws and that resales thereof may therefore be subject to the registration requirements of such acts.

An affiliate of Buyer owns an undivided interest in the Assets and it owns and operates other oil and gas properties similar in nature and kind to the Assets and is aware of the geologic factors and risks associated with operating oil and gas ▇▇▇▇▇ in the area of the Assets. Accordingly, Buyer assumes the risk of the downhole condition of the ▇▇▇▇▇. Except as expressly provided in this Agreement, Seller shall not have any liability to Buyer or its affiliates, agents, representatives or employees resulting from any use, authorized or unauthorized, of the Records or other information relating to the Assets provided by or on behalf of Seller.

ARTICLE 9

COVENANTS AND AGREEMENTS

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

(a) Operations Prior to Closing.

(1) Seller agrees to maintain Seller’s insurance now in effect with respect to the Assets through the date of Closing. From the date of execution of this Agreement to the Closing Date, Seller shall pay or cause to be paid all Property Expenses incurred in connection with the ownership or operation of the Assets. Except for Capital Projects listed on Exhibit F as of the date of this Agreement, Seller will timely notify Buyer of proposed activities and major capital expenditures that could reasonably be expected to cost in excess of $50,000 per activity (net to Seller’s interest) conducted on the Assets. Seller will keep Buyer timely informed of all material developments affecting any of the Assets.

(2) As of the date hereof, Seller has received the New Well Proposals attached as Exhibit N. Exhibit N sets forth the deadline date for Seller to make an election with respect to each New Well Proposal therein (each, an “Identified Well Deadline Date”). For example, the Identified Well Deadline Date for the Coronet 24-13-163-99H Well is April 25, 2012. Following the date hereof and until the Closing, it is contemplated that Seller shall receive proposals from an operator with associated costs or estimates thereof which exceed $50,000 per well net to Seller’s interest (the “Post-Signing Well Proposals”, and together with the New Well Proposals, the “Well Proposals”), with each such Post-Signing Well Proposal containing a deadline date for Seller to make an election to participate in the proposed operation set forth therein (each, a “Post-Signing Well Deadline Date”, and together with each Identified Well Deadline Date, a “Well Deadline Date”). At least two business days prior to the Well Deadline Date, Buyer shall notify Seller of whether Buyer would like Seller to consent to participate in the applicable Well Proposal; provided, that (A) Seller shall be obligated to make an election to participate in the Well Proposal if requested by Buyer and (B) to the extent the Well Deadline Date for a Well Proposal occurs three days or more following Closing and if Buyer does not inform Seller of whether Buyer would like Seller participate in such Well Proposal, then upon Closing, Buyer shall acquire all of Seller’s right to make such an election. Upon an election by Seller to participate in a Well Proposal which Buyer caused Seller to make, the applicable new well shall be considered a Capital Project and included among the Assets as a Well hereunder. If Buyer notifies Seller that it desires for Seller to elect to not participate in a Well Proposal, Seller may make such election (and provide notice of such election to Buyer) for its own account and the wellbore of the well associated with such proposal shall be excluded from the Assets at Closing; provided, further that if the operation to drill such well is a “Required Well” or a “Required Operation” as defined in Article XV.D of the Samson Operating Agreement, then the leases and only the leases that would be relinquished and assigned under Article XV.D of the Samson Operating Agreement shall also be excluded from the Assets at Closing; provided, further, that such well and leases shall only be excluded from the Assets if such well is actually drilled and Seller actually participates in such well and pays for its proportionate share of the drilling and completion operations for such well. If Closing does not occur because Buyer wrongfully fails to tender performance at Closing or otherwise breaches this Agreement prior to Closing and Seller is ready to close, Buyer shall assume and indemnify Seller from all liabilities for such operations for such new ▇▇▇▇▇ associated with the Well Proposals in which Buyer notified Seller that Buyer would like for Seller to participate in such proposals under the Samson Operating Agreement; and the interest of Seller in such ▇▇▇▇▇, at Seller’s option, may be deemed to be farmed out to Buyer under and pursuant to the terms provided for in the Farmout Agreement dated, September 28, 2011, as set forth on Exhibit D.

(3) As of the date hereof, Seller has received the proposals for elections under the AMI Clause attached as Exhibit O (each, an “Identified AMI Lease Acquisition Proposal”). Exhibit O sets forth the deadline date for Seller to make an election with respect to whether or not Seller shall participate in the costs of acquiring the oil and gas leases described therein (each, an “Identified AMI Lease Deadline Date”). For example, the Identified AMI Lease Deadline Date for the oil and gas lease dated January 31, 2012 from the City of ▇▇▇▇▇▇ is April 24, 2012.

Subject to subsection (c) below, Seller assumes all risk, liability, obligation and Losses in connection with, and shall defend, indemnify, and save and hold harmless Buyer and its affiliates, and their respective officers, directors, employees, members, and agents, from and against all Losses which arise from or in connection with (i) the Retained Liabilities, (ii) any matter for which Seller has agreed to indemnify Buyer under this Agreement, (iii) any breach by Seller of this Agreement, including covenants (excluding representations and warranties) and any assignment, document, certificate or agreement executed and delivered in connection with or pursuant to this Agreement (the “Transaction Documents”), and (iv) Seller’s breach of its representations and warranties in this Agreement and any Transaction Document.

(b) Buyer’s Indemnification of Seller. Buyer assumes all risk, liability, obligation and Losses in connection with, and shall defend, indemnify, and save and hold harmless Seller, its members, officers, directors, employees and agents, from and against all Losses which arise from or in connection with (i) the Assumed Liabilities, (ii) any matter for which Buyer has agreed to indemnify Seller under this Agreement, (iii) any breach by Buyer of this Agreement, including covenants and any Transaction Documents, and (iv) Buyer’s breach of its representations and warranties in this Agreement and any Transaction Documents.

(1) Time. If the Closing occurs, the representations and warranties of Seller and of Buyer, and in any certificate delivered, to the extent related to such representations and warranties, shall survive the Closing for a period of twenty-four (24) months; provided, however, that the Seller’s representations and warranties in Section 7.1 (Corporate Representations), Section 7.2 (Authorization and Enforceability), and Section 7.18 (Taxes) (collectively, the “Fundamental and Tax Representations”), and the Buyer’s representations and warranties in Section 8.1 (Corporate Representations) and Section 8.2 (Authorization and Enforceability) shall survive the Closing and shall continue indefinitely, and the Seller’s representation and warranty in Section 5.1(a) (Title) shall survive the Closing until June 30, 2012. Each covenant and agreement of the Parties contained in this Agreement that requires performance prior to the Closing shall survive the Closing for a period of twenty-four (24) months, and each covenant and agreement of the Parties contained in this Agreement that requires performance following the Closing shall survive the Closing indefinitely unless otherwise stated herein. Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim duly asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(2) Threshold. Seller shall have no liability for any indemnification under this Article 15, until and unless the aggregate amount of the liability for all Losses for which Claim Notices are delivered by Buyer exceeds 1% of the Purchase Price (the “Indemnity Threshold”). The Indemnity Threshold is a threshold and not a deductible. This section shall not limit indemnification with respect to (i) fraud, (ii) breaches of the Fundamental and Tax Representations, or (iii) breaches of covenants of the Parties contained in this Agreement and the Transaction Documents. This section shall limit indemnification with respect to breaches of representations and warranties in this Agreement (other than Fundamental and Tax Representations and other than with respect to fraud).

(3) Title Defects, Environmental Defects. With respect to Title Defects and Environmental Defects, the thresholds set forth in Articles 5 and 6 shall apply; provided, however, that the Title Threshold shall be considered one threshold for all purposes under this Agreement, whether Buyer submits a Title Defect pre-Closing pursuant to Section 5.2 or a claim for indemnification pursuant to Article 15, and accordingly, each Title Defect Value associated with each Title Defect submitted pursuant to Section 5.2 shall count toward the Title Threshold both before and after Closing.

(4) Retained Liabilities - Subsections 15.2 (i) through (vi). With respect to Retained Liabilities as set forth in subsections 15.2 (i) through (vi), there shall be no thresholds.

(5) Special Warranty of Title. With respect to Seller’s special warranty of title given in Exhibit I, Seller’s indemnity obligation shall be limited to the Allocated Value of the particular Asset.

15.5. Procedure. The indemnifications contained in Section 15.4 shall be implemented as follows:

(a) Coverage. Such indemnity shall extend to all Losses suffered or incurred by the Indemnified Party.

(b) 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 shall provide: (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. Subject to Section 15.5(c), the amount claimed shall be paid by the Indemnifying Party to the extent required herein within 30 days after receipt of the Claim Notice, or after the amount of such payment has been finally established, whichever last occurs.

(c) Information. If the Indemnified Party receives notice of a claim or legal action that may result in a loss for which indemnification may be sought under this Article 15 (a “Claim”), the Indemnified Party shall endeavor to give written notice of such Claim to the Indemnifying Party as soon as is practicable. 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 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 the conduct of litigation through attorneys of the Indemnifying Party’s choice; provided, however, that any settlement of the claim by the Indemnifying Party may not result in any liability or cost to the Indemnified Party without its prior written 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. 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 15 applies until the Indemnifying Party assumes such defense. If the Indemnifying Party fails to assume such defense within the time period provided above, the Indemnified Party may settle the Claim, in its reasonable discretion at the Indemnifying Party’s expense. 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.

15.6. Dispute Resolution(k). Only if the Closing occurs, the Parties agree to resolve all “disputes” concerning this Agreement pursuant to the provisions of this section, excluding those matters addressed under Articles 5, 6, 12, and 14. The Parties agree to submit all Disputes to binding arbitration in Denver, Colorado such arbitration to be conducted as follows: The arbitration proceeding shall be governed by North Dakota law and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, with discovery to be conducted in accordance with the Federal Rules of Civil Procedure, and with any disputes over the scope of discovery to be determined by the arbitrators. The arbitration shall initially be before a panel of three arbitrators. Each party shall select an arbitrator and selected arbitrators shall jointly select the single neutral arbitrator. The party-selected arbitrators shall then withdraw from the proceeding. All arbitrators shall have material experience in matters involving oil and gas exploration and production and shall not have been engaged by either Party. The arbitrator shall conduct a hearing no later than 60 days after submission of the matter to arbitration, and the arbitrator shall render a written decision within 30 days of the hearing. 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 it determines to be relevant, in accordance with procedures that it determines to be appropriate. Any award entered in the arbitration shall be made by a written opinion stating the reasons and basis for the award made and any payment due pursuant to the arbitration shall be made within 15 days after the arbitrator’s decision. The final decision may be filed in a court of competent jurisdiction and may be enforced by either Party as a final judgment of such court. Each Party shall bear its own costs and expenses of the arbitration, provided, however, that the costs of employing the arbitrators will be shared equally by the Parties.

15.7. No Insurance; Subrogation. The indemnifications provided in this Article 15 shall not be construed as a form of insurance. Buyer and Seller hereby waive for themselves, their respective successors or assigns, including, without limitation, any insurers, any rights to subrogation for Losses for which each of them is respectively liable or against which each respectively indemnifies the other, and, if required by applicable policies, Buyer and Seller shall obtain waivers of such subrogation from their respective insurers.

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