(b) all wells located on any of the Leases or on any other lease with which any Lease has been unitized (such interest in such wells, including the wells set forth in Exhibit A-1, the “Wells”), and in all Hydrocarbons produced therefrom or allocated thereto;

(c) all rights and interests in, under or derived from all unitization and pooling agreements in effect with respect to any of the Leases or Wells and the units created thereby (the “Units”);

(d) to the extent that they may be assigned or the extent they may be assigned upon payment of a fee or other consideration, and Buyer has paid such fee or other consideration, all Applicable Contracts and all rights thereunder, including certain firm transportation agreements;

(e) to the extent that they may be assigned or the extent they may be assigned upon payment of a fee or other consideration, and Buyer has paid such fee or other consideration, all permits, licenses, servitudes, easements and rights-of-way to the extent used primarily in connection with the ownership or operation of any of the Leases, Wells, Units or other Assets;

(g) all Imbalances relating to the Assets;

(h) all Hedges;

(i) all of the files, records, information and data, whether written or electronically stored, primarily relating to the Assets in Seller’s or its Affiliates’ possession, including: (i) land and title records (including abstracts of title, title opinions and title curative documents); (ii) Applicable Contract files; (iii) correspondence; (iv) operations, environmental and production records; (v) facility and well records; (vi) geologic technical data, including logs, maps and Seller’s interpretations thereof; and (vii) copies of any environmental studies that have been prepared with respect to the Assets, which studies shall be delivered to Buyer in accordance with the provisions of Section 9.4 (collectively, “Records”); and

2.2 Excluded Assets. Seller shall reserve and retain all of the Excluded Assets.

2.3 Revenues and Expenses. Subject to the provisions hereof, Seller shall remain entitled to all of the rights of ownership (including the right to all production, proceeds of production (including realized gains on Hedges) and other proceeds) and shall remain responsible (by payment, through the adjustments to the Purchase Price hereunder or otherwise) for all Operating Expenses, in each case, attributable to the Assets for the period of time prior to the Effective Time. Subject to the provisions hereof, and subject to the occurrence of Closing, Buyer shall be entitled to all of the rights of ownership (including the right to all production, proceeds of production and other proceeds), and shall be responsible (by payment, through the adjustments to the Purchase Price hereunder or otherwise) for all Operating Expenses, in each case, attributable to the Assets for the period of time from and after the Effective Time. “Operating Expenses” means all operating expenses (including costs of insurance and ad valorem, property, severance, production and similar Taxes based upon or measured by or attributable to the ownership or operation of the Assets or the production of Hydrocarbons therefrom, but excluding any other Taxes) and capital expenditures incurred in the ownership and operation of the Assets in the ordinary course of business and, where applicable, in accordance with the relevant operating or unit agreement, if any, and overhead costs charged to the Assets under the relevant operating agreement or unit agreement, if any, but excluding Liabilities attributable to (i) personal injury or death, property damage or violation of any Law, (ii) Decommission obligations, (iii) environmental matters, including obligations to remediate any contamination of water or Personal Property under applicable Environmental Laws, (iv) obligations with respect to Imbalances, or (v) obligations to pay Working Interests, royalties, overriding royalties or other interest owners revenues or proceeds attributable to sales of Hydrocarbons relating to the Assets, including those held in suspense.

3.4 Adjustment Methodology. When available, actual figures will be used for the adjustments to the Purchase Price at Closing. To the extent actual figures are not available, estimates will be used subject to final adjustments in accordance with Section 3.7 and Section 3.8.

3.5 Preliminary Settlement Statement. Not less than six (6) Business Days prior to Closing, Seller shall prepare and submit to Buyer for review a draft settlement statement (the “Preliminary Settlement Statement”) that shall set forth the Adjusted Purchase Price, reflecting each adjustment made in accordance with this Agreement as of the date of preparation of such Preliminary Settlement Statement and the calculation of the adjustments used to determine such amount, together with the designation of Seller’s accounts for the wire transfers of funds as required by Section 3.1 and Section 9.3(d). Within two (2) Business Days of receipt of the Preliminary Settlement Statement, Buyer will deliver to Seller a written report containing all changes with the explanation therefor that Buyer proposes to be made to the Preliminary Settlement Statement. The Parties shall in good faith attempt to agree on the Preliminary Settlement Statement as soon as possible after Seller’s receipt of Buyer’s written report. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Purchase Price at Closing; provided that if the Parties do not agree upon an adjustment set forth in the Preliminary Settlement Statement, then the amount of such adjustment used to adjust the Purchase Price at Closing shall be that amount set forth in the draft Preliminary Settlement Statement delivered by Seller to Buyer pursuant to this Section 3.5.

3.6 Interim Settlement Statement. On or before August 31, 2012, an interim settlement statement (the “Interim Settlement Statement”) will be prepared by Seller, based on the Unpaid Capital Costs attributable to and actual income received and expenses paid during the period of time commencing with the Effective Time and ending at 7:00 a.m. (Central Time) on August 31, 2012, that shall set forth an interim Purchase Price adjustment amount, reflecting only those adjustments to be made to the Purchase Price pursuant to Sections 3.3(a)(ii), 3.3(b)(i) and 3.3(b)(xi) of this Agreement as of the date of preparation of such Interim Settlement Statement and the calculation of the adjustments used to determine such amount. Within two (2) Business Days of receipt of the Interim Settlement Statement, Buyer will deliver to Seller a written report containing all changes with the explanation therefor that Buyer proposes to be made to the Interim Settlement Statement. The Parties shall in good faith attempt to agree on the Interim Settlement Statement as soon as possible after Seller’s receipt of Buyer’s written report. In the event the Parties agree to the amounts set forth in the Interim Settlement Statement, the interim Purchase Price adjustment amount determined pursuant to this Section 3.6 shall be paid by the owing Party within ten (10) days of such agreement as to such owed amounts to the owed Party. If the Parties do not agree upon the interim Purchase Price adjustment amount set forth in the Interim Settlement Statement by September 15, 2012, then the amount of such adjustment to be paid to the owed Party shall be that amount set forth in the draft Interim Settlement Statement delivered by Seller to Buyer pursuant to this Section 3.6, such amount to be paid by the owing Party by September 25, 2012 to the owed Party. All amounts paid pursuant to this Section 3.6 shall be delivered in United States currency by wire transfer of immediately available funds to the account specified in writing by the relevant Party.

3.7 Final Settlement Statement. On or before one hundred eighty (180) days after Closing, a final settlement statement (the “Final Settlement Statement”) will be prepared by Seller, based on actual income and expenses during the Interim Period and which takes into account all final adjustments made to the Purchase Price and shows the resulting final Purchase Price (the “Final Price”). The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within thirty (30) days, after receipt of the Final Settlement Statement, Buyer shall return to Seller a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). Any changes not so specified in the Dispute Notice shall be deemed waived and Seller’s determinations with respect to all such elements of the Final Settlement Statement that are not addressed specifically in the Dispute Notice shall prevail. If Buyer fails to timely deliver a Dispute Notice to Seller containing changes Buyer proposes to be made to the Final Settlement Statement, the Final Settlement Statement as delivered by Seller will be deemed to be correct and will be final and binding on the Parties and not subject to further audit or arbitration. If the Final Price set forth in the Final Settlement Statement is mutually agreed upon by Seller and Buyer, the Final Settlement Statement and the Final Price, shall be final and binding on the Parties hereto (other than with respect to amounts not accounted for therein or settled thereby, which amounts shall be subject to the provisions of Section 3.10). Any difference in the Adjusted Purchase Price as paid at Closing pursuant to the Preliminary Settlement Statement (as adjusted by any interim Purchase Price adjustment amount paid pursuant to Section 3.6) and the Final Price shall be paid by the owing Party within ten (10) days of final determination of such owed amounts in accordance herewith to the owed Party. All amounts paid pursuant to this Section 3.7 shall be delivered in United States currency by wire transfer of immediately available funds to the account specified in writing by the relevant Party.

3.8 Disputes. If Seller and Buyer are unable to resolve the matters addressed in the Dispute Notice, each of Buyer and Seller shall within ten (10) Business Days after the delivery of such Dispute Notice, summarize its position with regard to such dispute in a written document of twenty pages or less and submit such summaries to the Denver, Colorado office of Ernst & Young or such other Person as the Parties may mutually select (the “Accounting Arbitrator”), together with the Dispute Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. Within ten (10) Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall render a decision choosing either Seller’s position or Buyer’s position with respect to each matter addressed in any Dispute Notice, based on the materials described above. Any decision rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on Seller and Buyer and will be enforceable against any of the Parties in any court of competent jurisdiction. The costs of such Accounting Arbitrators shall be borne one-half by Buyer and one-half by Seller.

3.9 Allocation of Purchase Price / Allocated Values. Buyer and Seller agree that the Purchase Price and any Assumed Obligation or other items treated as consideration for federal income Tax purposes shall be allocated among the Assets in accordance with Section 1060 of the Code as set forth in Schedule 3.8 to this Agreement (the “Allocated Values”). Each Party shall utilize the Allocated Values, as updated by mutual agreement of the Parties to reflect any adjustment to the Purchase Price pursuant to this Agreement for purposes of all federal, state and local Tax returns and reports, including Internal Revenue Service Form 8594, and neither any Party or its Affiliates shall take any position on any Tax return that is inconsistent with such Allocated Values, as adjusted, unless such position is mutually agreed by the Parties or required to be taken pursuant to a final determination, as defined in Section 1313 of the Code. Buyer and Seller agree that such allocation, as adjusted, is reasonable and shall not take any position inconsistent therewith, including in notices to Preferential Purchase Right holders. Seller and Buyer agree to promptly advise the other regarding the existence of any Tax audit or controversy regarding the correctness of the Allocated Values or any adjustment thereto.

3.10 Post-Closing Adjustments after Final Settlement Statement. If, during the period from and after the Parties’ agreement upon the Final Settlement Statement up until the second (2nd) anniversary of Closing, (a) any Party receives monies belonging to the other, including proceeds of production, then such amount shall immediately be paid over to the proper Party, (b) any Party pays monies for Operating Expenses which are the obligation of the other Party hereto, then such other Party shall promptly reimburse the Party which paid such Operating Expenses upon receipt of an invoice from such paying Party, (c) a Party receives an invoice of an expense or obligation which is owed by the other Party, such Party receiving the invoice shall promptly forward such invoice to the Party obligated to pay the same, and (d) if an invoice or other evidence of an obligation is received by a Party, which is partially an obligation of both Seller and Buyer, then the Parties shall consult with each other, and each shall promptly pay its portion of such obligation to the obligee.

3.11 Allocation for Imbalances. If, prior to one hundred eighty (180) days following Closing, either Party discovers an error in the Imbalances set forth in Schedule 4.12 or updated amounts are available for those Imbalances set forth on Schedule 4.12 that are identified as not being current as of the Effective Time, then the Purchase Price shall be further adjusted either at Closing or pursuant to the Final Settlement Statement pursuant to Section 3.3(a)(v), Section 3.3(a)(vi), Section 3.3(b)(vi) or Section 3.3(b)(vii), as applicable, and Schedule 4.12 will be deemed amended immediately prior to Closing to reflect the Imbalances for which the Purchase Price is so adjusted.

In the event that any counterparty to any such Guarantee does not release Seller and its Affiliates, then, from and after Closing, Buyer shall indemnify Seller or its relevant Affiliate against all amounts incurred by Seller or its relevant Affiliate under such Guarantee (and all costs incurred in connection with such Guarantee) if applicable to Assets acquired by Buyer. Notwithstanding anything to the contrary contained in this Agreement, any cash placed in escrow by Seller or any Affiliate of Seller pursuant to the Guarantees must be returned to Seller, and shall be deemed an Excluded Asset.

(c) Buyer shall coordinate its environmental property assessments and physical inspections of the Assets with Seller and all Third Party operators to minimize any inconvenience to or interruption of the conduct of business by Seller or such Third Party operators.

ARTICLE XI

TITLE MATTERS; CASUALTY; TRANSFER RESTRICTIONS

11.1 Seller’s Title.

(a) General Disclaimer of Title Warranties and Representations. Except for the special warranty of title as set forth in Section 11.1(b) and without limiting Buyer’s remedies for Title Defects set forth in this Article XI, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to Seller’s title to any of the Assets and 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 Assets (i) before Closing, shall be as set forth in Section 11.2 and (ii) after Closing, shall be pursuant to the special warranty of title set forth in Section 11.1(b).

(b) Special Warranty of Title. If Closing occurs, then effective as of the Closing Date, Seller warrants Defensible Title to the Assets (but, with respect to any Lease and any Well or Undrilled Location associated therewith, limited to the depths set forth in Exhibit A or Exhibit A-1, as applicable) unto Buyer against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller or its Affiliates, but not otherwise, subject, however, to the Permitted Encumbrances and to any matters of record in the applicable counties or in the applicable state or federal records prior to the Defect Claim Date; provided, however, that, except with respect to any liability of Seller for any claim asserted in writing by Buyer to Seller in accordance with Section 11.1(c) on or before the expiration of the Survival Period for breach of such special warranty, such special warranty shall cease and terminate at the end of such Survival Period. Said special warranty of title shall be subject to the further limitations and provisions of this Article XI.

(i) Buyer’s Assertion of Title Warranty Breaches. Prior to the expiration of the period of time commencing as of the Closing Date and ending at 5 p.m. Central Time on the twelve (12) month anniversary thereof (the “Survival Period”), Buyer shall furnish Seller a Title Defect Notice meeting the requirements of Section 11.2(a) setting forth any matters which Buyer intends to assert as a breach of Seller’s special warranty in Section 11.1(b). For all purposes of this Agreement, Buyer shall be deemed to have waived, and Seller shall have no further liability for, any breach of Seller’s special warranty that Buyer fails to assert by a Title Defect Notice given to Seller on or before the expiration of the Survival Period. Seller shall have a reasonable opportunity, but not the obligation, to cure any Title Defect asserted by Buyer pursuant to this Section 11.1(c)(i). Buyer agrees to reasonably cooperate with any attempt by Seller to cure any such Title Defect.

(ii) Limitations on Special Warranty. For purposes of Seller’s special warranty of title, the value of the Wells and/or Undrilled Locations set forth in Schedule 3.8, as appropriate (but limited to the depths, if any, set forth on Exhibit A-1 for such Well and/or Undrilled Location), shall be deemed to be the Allocated Value thereof, as adjusted herein. Recovery on Seller’s special warranty of title shall be limited to an amount (without any interest accruing thereon) equal to the reduction in the Purchase Price to which Buyer would have been entitled had Buyer asserted the Title Defect giving rise to such breach of Seller’s special warranty of title as a Title Defect prior to Closing pursuant to Section 11.2, in each case taking into account the Individual Title Defect Threshold and the Aggregate Deductible. Seller shall be entitled to offset any amount owed by Seller for breach of its special warranty of title with respect to any Asset by the amount of any Title Benefits with respect to such Asset as to which Seller gives Buyer notice after the Defect Claim Date.

11.2 Notice of Title Defects; Defect Adjustments.

(a) Title Defect Notices. Buyer must deliver at least five (5) Business Days before Closing (the “Defect Claim Date”) claim notices to Seller meeting the requirements of this Section 11.2(a) (collectively the “Title Defect Notices” and individually a “Title Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Section 11.2(a). For all purposes of this Agreement and notwithstanding anything herein to the contrary (except as provided in Section 11.1), Buyer shall be deemed to have waived, and Seller shall have no liability for, any Title Defect which Buyer fails to assert as a Title Defect by a properly delivered Title Defect Notice received by Seller on or before the Defect Claim Date; provided, however, that, for purposes of Seller’s special warranty to title under Section 11.1(b), such waiver shall not apply to any matter that prior to the Defect Claim Date is not reflected of record in the applicable counties or in the applicable state or federal records. To be effective, each Title Defect Notice shall be in writing, and shall include (i) a description of the alleged Title Defect and the Asset, or portion thereof, affected by such Title Defect (each a “Title Defect Property”), (ii) the Allocated Value of each Title Defect Property, (iii) supporting documents reasonably necessary for Seller to verify the existence of such alleged Title Defect, and (iv) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by such alleged Title Defect and the computations upon which Buyer’s belief is based. Buyer shall promptly upon discovery furnish Seller with written notice of any Title Benefit which is discovered by any of Buyer’s or any of its Affiliate’s employees, title attorneys, landmen or other title examiners while conducting Buyer’s due diligence with respect to the Assets prior to the Defect Claim Date.

(b) Title Benefit Notices. Seller shall have the right, but not the obligation, to deliver to Buyer on or before the Defect Claim Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (i) a description of the alleged Title Benefit and the Asset, or portion thereof, affected by such alleged Title Benefit (each a “Title Benefit Property”), and (ii) the amount by which Seller reasonably believes the Allocated Value of such Title Benefit Property is increased by such alleged Title Benefit and the computations upon which Seller’s belief is based. Seller shall be deemed to have waived all Title Benefits for which a Title Benefit Notice has not been delivered on or before the Defect Claim Date.

(c) Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure at any time prior to the expiration of one hundred and eighty (180) days following Closing (the “Cure Period”), any Title Defects of which it has timely received a Title Defect Notice from Buyer. During the period of time from Closing to the expiration of the Cure Period, Buyer hereby agrees to afford Seller and its officers, employees, agents and other authorized representatives reasonable access, during normal business hours, to the Assets and all Records in Buyer’s or any of its Affiliates’ possession in order that Seller may attempt to cure any such Title Defects.

(d) Remedies for Title Defects. Subject to Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto and subject to the rights of the Parties pursuant to Section 14.1(c), in the event that any Title Defect timely asserted by Buyer in accordance with Section 11.2(a) is not waived in writing by Buyer or cured prior to Closing, Seller shall, at its sole option, elect to:

(i) subject to the Individual Title Defect Threshold and the Aggregate Deductible, reduce the Purchase Price by the Title Defect Amount determined pursuant to Section 11.2(h) or Section 11.2(k);

(ii) retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Title Defect Property and such associated Assets; or

(iii) if applicable, terminate this Agreement pursuant to Section 14.1(c).

(e) Post-Closing Payments/Adjustments.

(i) In the event that an adjustment for a Title Defect Amount is made to the Purchase Price and Seller thereafter cures, during the Cure Period, the Title Defect(s) for which such adjustment was made, then, at Seller’s election, (A) the Final Price reflected in the Final Settlement Statement shall be adjusted upward by the amount by which the Purchase Price was adjusted on account of such Title Defect(s) at Closing, or (B) Buyer shall promptly, but in any event within ten (10) Business Days after such Title Defect(s) has been cured and Buyer has received written notice from Seller thereof, together with supporting documentation available to Seller reasonably necessary to verify such cure of such Title Defect(s), pay to Seller the amount by which the Purchase Price was adjusted on account of such Title Defect(s).

(ii) In the event Seller retained the entirety of a Title Defect Property pursuant to Section 11.2(d) at Closing and Seller thereafter cures, during the Cure Period, the Title Defect(s) affecting such Title Defect Property, then, (A) at Seller’s election, (x) the Final Price reflected in the Final Settlement Statement shall be adjusted upward by the Allocated Value of such Title Defect Property and any associated Assets, or (y) Buyer shall promptly, but in any event within ten (10) Business Days after such Title Defect(s) has been cured and Buyer has received written notice from Seller thereof, together with supporting documentation available to Seller reasonably necessary to verify such cure of such Title Defect(s), pay to Seller the Allocated Value of the Title Defect Property, and (B) promptly following receipt of payment, Seller shall convey the Title Defect Property to Buyer pursuant to an assignment and bill of sale substantially in the form attached to this Agreement as Exhibit B.

(f) Remedies for Title Benefits. With respect to each Title Benefit Property reported under Section 11.2(b), the Purchase Price shall be increased by an amount (the “Title Benefit Amount”) equal to the increase in the Allocated Value for such Title Benefit Property caused by such Title Benefit, as determined pursuant to Section 11.2(i) or Section 11.2(k).

(g) Exclusive Remedy. Except for Buyer’s rights under Seller’s special warranty of title under Section 11.1(b) and Buyer’s rights to terminate this Agreement pursuant to Section 14.1(c), the provisions set forth in Section 11.2(d) shall be the exclusive right and remedy of Buyer with respect to Seller’s failure to have Defensible Title with respect to any Asset or any other title matter.

(h) Title Defect Amount. The amount by which the Allocated Value of a Title Defect Property is reduced as a result of the existence of a Title Defect shall be the “Title Defect Amount” and shall be determined in accordance with the following terms and conditions:

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

(ii) if the Title Defect is an Encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii) if the Title Defect represents a discrepancy between (A) Seller’s Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest set forth for such Title Defect Property in Exhibit A-1, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest set forth for such Title Defect Property in Exhibit A-1;

(iv) if the Title Defect represents an obligation or Encumbrance upon or other defect in title to the Title Defect Property of a type not described above, then the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the reasonable cost and expense of curing such Title Defect;

(v) the Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder; and

(vi) notwithstanding anything to the contrary in this Article XI, 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.

(i) Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions:

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

(ii) if the Title Benefit represents a discrepancy between (A) Seller’s Net Revenue Interest for any Title Benefit Property and (B) the Net Revenue Interest set forth for such Title Benefit Property in Exhibit A-1, then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property multiplied by a fraction, the numerator of which is the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest set forth for such Title Benefit Property in Exhibit A-1; and

(iii) if the Title Benefit is of a type not described above, then the Title Benefit Amounts shall be determined by taking into account the Allocated Value of Title Benefit Property, the portion of such Title Benefit Property affected by such Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of such Title Benefit Property, the values placed upon the Title Benefit by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation.

(j) Title Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Title Defect for which the Title Defect Amount does not exceed $100,000 (the “Individual Title Defect Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Title Defect that exceeds the Individual Title Defect Threshold unless (A) the amount of the sum of (1) the aggregate Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold (but excluding any such Title Defects cured by Seller), plus (2) the aggregate Remediation Amounts of all Environmental Defects that exceed the Individual Environmental Threshold (but excluding any Environmental Defects cured by Seller), exceeds (B) the Aggregate Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other applicable remedies available hereunder, but, only with respect to the aggregate amount of such Title Defect Amounts and Remediation Amounts in excess of the Aggregate Deductible. For the avoidance of doubt, if Seller retains any Title Defect Property pursuant to Section 11.2(d)(ii), the Title Defect Amount related to such Title Defect Property will not be counted towards the Aggregate Deductible.

(k) Title Dispute Resolution. Seller and Buyer shall attempt to agree on all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Title Defect Amounts and Title Benefit Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 11.2(k). There shall be a single arbitrator, who shall be a title attorney with at least ten (10) years experience in oil and gas titles involving properties in the regional area in which the Title Defect Properties are located, as selected by mutual agreement of Buyer and Seller within fifteen (15) days after the end of the Cure Period, and absent such agreement, by the Denver, Colorado office of the American Arbitration Association (the “Title Arbitrator”). The arbitration proceeding shall be held in Denver, Colorado and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 11.2(k). The Title Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making its determination, the Title Arbitrator shall be bound by the rules set forth in Section 11.2(h) and Section 11.2(i) and, subject to the foregoing, may consider such other matters as in the opinion of the Title Arbitrator are necessary to make a proper determination. The Title Arbitrator, however, may not award the Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect, Title Benefit, Title Defect Amount and/or Title Benefit Amount submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Title Arbitrator. To the extent that the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.5 or Section 3.7, then within ten (10) days after the Title Arbitrator delivers written notice to Buyer and Seller of his award with respect to a Title Defect Amount or a Title Benefit Amount and, subject to Section 11.2(j) (i) Buyer shall pay to Seller the amount, if any, so awarded by the Title Arbitrator to Seller, and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer. Nothing herein shall operate to cause Closing to be delayed on account of any arbitration conducted pursuant to this Section 11.2(k) and, to the extent any adjustments are not agreed upon by the Parties as of Closing, the Purchase Price shall not be adjusted therefor at Closing and subsequent adjustments to the Purchase Price, if any, will be made pursuant to Section 3.7 or this Section 11.2.

11.3 Casualty Loss.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time, if Closing occurs, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the depreciation of Personal Property due to ordinary wear and tear, in each case, with respect to the Assets.

(b) If, after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty (each, a "Casualty Loss"), the Closing shall nevertheless occur despite such Casualty Loss without any adjustment to the Purchase Price, and Seller, at Closing, shall pay to Buyer all sums paid to Seller by Third Parties by reason of any Casualty Loss insofar as with respect to the Assets and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller's right, title and interest (if any) in insurance claims, unpaid awards, and other rights against Third Parties (excluding any Liabilities, other than insurance claims, of or against any Seller Indemnified Parties) arising out of such Casualty Loss insofar as with respect to the Assets; provided, however, that Seller shall reserve and retain (and Buyer shall assign to Seller) all right, title, interest and claims against Third Parties for the recovery of Seller's costs and expenses incurred prior to Closing in pursuing or asserting any such insurance claims or other rights against Third Parties to the extent no adjustment has been made in Seller’s favor under Section 3.3 for such costs and expenses.

11.4 Preferential Purchase Rights and Consents to Assign.

(a) With respect to each Preferential Purchase Right set forth in Schedule 4.10, Seller, prior to Closing, shall send to the holder of each such Preferential Purchase Right a notice in material compliance with the contractual provisions applicable to such Preferential Purchase Right.

(i) If, prior to Closing, any holder of a Preferential Purchase Right notifies Seller that it intends to consummate the purchase of the Asset to which its Preferential Purchase Right applies or if the time for exercising such Preferential Purchase Right has not expired, then the Asset subject to such Preferential Purchase Right shall be excluded from the Assets to be assigned to Buyer at Closing (but only to the extent of the portion of such Asset affected by the Preferential Purchase Right), and the Purchase Price shall be reduced by the Allocated Value of the Asset (or portion thereof) so excluded. Seller shall be entitled to all proceeds paid by any Person exercising a Preferential Purchase Right prior to Closing. If such holder of such Preferential Purchase Right thereafter fails to consummate the purchase of the Asset (or portion thereof) covered by such Preferential Purchase Right on or before sixty (60) days following the Closing Date, or the time for exercising such Preferential Purchase Right expires without exercise by the holder thereof (A) Seller shall so notify Buyer and (B) Buyer shall purchase, on or before ten (10) days following receipt of such notice, such Asset (or portion thereof) that was so excluded from Seller, under the terms of this Agreement and for a price equal to the amount by which the Purchase Price was reduced at Closing with respect to such excluded Asset (or portion thereof).

(ii) All Assets for which any applicable Preferential Purchase Right has been waived, or as to which the period to exercise the applicable Preferential Purchase Right has expired, in each case, prior to Closing, shall be sold to Buyer at Closing pursuant to the provisions of this Agreement.

(b) With respect to each Consent set forth in Schedule 4.4, Seller, prior to Closing, shall send to the holder of each such Consent a notice in material compliance with the contractual provisions applicable to such Consent seeking such holder’s consent to the transactions contemplated hereby.

(i) If (A) Seller fails to obtain a Consent set forth in Schedule 4.4 prior to Closing and the failure to obtain such Consent would cause (1) the assignment of the Assets affected thereby to Buyer to be void or (2) the termination of a Lease under the express terms thereof or (B) a Consent requested by Seller is denied in writing, then, in each case, the Asset (or portion thereof) affected by such un-obtained Consent shall be excluded from the Assets to be assigned to Buyer at Closing, and the Purchase Price shall be reduced by the Allocated Value of such Asset (or portion thereof) so excluded. In the event that a Consent (with respect to an Asset excluded pursuant to this Section11.4(b)(i)) that was not obtained prior to Closing is obtained within sixty (60) days following Closing, then, within ten (10) days after such Consent is obtained (x) Buyer shall purchase the Asset (or portion thereof) that was so excluded as a result of such previously un-obtained Consent and pay to Seller the amount by which the Purchase Price was reduced at Closing with respect to the Asset (or portion thereof) so excluded and (y) Seller shall assign to Buyer the Asset (or portion thereof) so excluded at Closing pursuant to an instrument in substantially the same form as the Assignment.

(ii) If Seller fails to obtain a Consent set forth in Schedule 4.4 prior to Closing (A) and the failure to obtain such Consent would not cause (1) the assignment of the Asset (or portion thereof) affected thereby to Buyer to be void or (2) the termination of a Lease under the express terms thereof and (B) such Consent requested by Seller is not denied in writing by the holder thereof, then the Asset (or portion thereof) subject to such un-obtained Consent shall nevertheless be assigned by Seller to Buyer at Closing as part of the Assets and Buyer shall have no claim against, and Seller shall have no Liability for, the failure to obtain such Consent.

(iii) Prior to Closing, Seller and Buyer shall use their commercially reasonable efforts to obtain all Consents listed on Schedule 4.4; provided, however, that neither Party shall be required to incur any Liability or pay any money in order to obtain any such Consent. Subject to the foregoing, Buyer hereby agrees to provide Seller with any information or documentation that may be reasonably requested by Seller and/or the Third Party holders of such Consents in order to facilitate the process of obtaining such Consents.

ARTICLE XII

ENVIRONMENTAL MATTERS

12.1 Notice of Environmental Defects.

(a) Environmental Defects Notice. Buyer must deliver, at or prior to the Defect Claim Date, claim notices to Seller meeting the requirements of this Section 12.1(a) (collectively the “Environmental Defect Notices” and individually an “Environmental Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Environmental Defects and which Buyer intends to assert as Environmental Defects pursuant to this Section 12.1. For all purposes of this Agreement, but subject to Buyer’s remedy for a breach of Seller’s representation contained in Section 4.14, Buyer shall be deemed to have waived, and Seller shall have no liability for, any Environmental Defect which Buyer fails to assert as an Environmental Defect by a properly delivered Environmental Defect Notice received by Seller on or before the Defect Claim Date. To be effective, each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter constituting the alleged Environmental Condition (including the applicable Environmental Law violated or implicated thereby) and the Assets affected by such alleged Environmental Condition, (ii) the Allocated Value of the Assets (or portions thereof) affected by such alleged Environmental Condition, (iii) supporting documents reasonably necessary for Seller to verify the existence of such alleged Environmental Condition, and (iv) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Defect. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the alleged Environmental Condition that gives rise to the asserted Environmental Defect and identify all assumptions used by the Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws. Seller shall have the right, but not the obligation, to cure any asserted Environmental Defect on or before Closing.

(b) Remedies for Environmental Defects. Subject to Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Remediation Amount asserted with respect thereto, and subject to the rights of the Parties pursuant to Section 14.1(c), in the event that any Environmental Defect timely asserted by Buyer in accordance with Section 12.1(a) is not waived in writing by Buyer or cured during the Cure Period, Seller shall, at its sole option, elect to:

(i) subject to the Individual Environmental Threshold and the Aggregate Deductible, reduce the Purchase Price by the Remediation Amount;

(ii) assume responsibility for the Remediation of such Environmental Defect;

(iii) retain the entirety of the Asset that is subject to such Environmental Defect, together with all associated Assets, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Asset and such associated Assets; or

(iv) if applicable, terminate this Agreement pursuant to Section 14.1(c).

If Seller elects the option set forth in clause (i) above, and if Closing occurs, Buyer shall be deemed to have assumed responsibility for all of the costs and expenses attributable to the Remediation of the Environmental Condition attributable to such Environmental Defect and all of all Liabilities with respect thereto and such responsibility of Buyer shall be deemed to constitute part of the Assumed Obligations hereunder. If Seller elects the option set forth in clause (ii) above, Seller shall use reasonable efforts to implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion for the type of Remediation that Seller elects to undertake and Buyer, effective as of Closing, hereby grants to Seller and its representatives, access to the Assets to conduct such Remediation. Seller will be deemed to have adequately completed the Remediation required in the immediately preceding sentence (A) upon receipt of a certificate or approval from the applicable Governmental Authority that the Remediation has been implemented to the extent necessary to comply with existing Laws or (B) upon receipt of a certificate from a licensed professional engineer that the Remediation has been implemented to the extent necessary to comply with existing Laws.

(c) Exclusive Remedy. Except for Buyer’s remedy for a breach of Seller’s representation contained in Section 4.14 and Buyer’s rights to terminate this Agreement pursuant to Section 14.1(c), the provisions set forth in Section 12.1(b) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect with respect to any Asset or other environmental matter.

(d) Environmental Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Environmental Defect for which the Remediation Amount does not exceed $100,000 (the “Individual Environmental Threshold”); and (ii) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Threshold unless (A) the amount of the sum of (1) the aggregate Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold (but excluding any Environmental Defects cured by Seller), plus (2) the aggregate Title Defect Amounts of all Title Defects that exceed the Individual Title Defect Threshold (but excluding any Title Defects cured by Seller), exceeds (B) the Aggregate Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price or other applicable remedies available hereunder, but only with respect to the aggregate amount of such Remediation Amounts and Title Defect Amounts in excess of the Aggregate Deductible. For the avoidance of doubt, if Seller retains any Assets pursuant to Section 12.1(b)(iii), the Remediation Amounts relating to such retained Assets will not be counted towards the Aggregate Deductible.

(e) Environmental Dispute Resolution. Seller and Buyer shall attempt to agree on all Environmental Defects and Remediation Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 12.1(e). There shall be a single arbitrator, who shall be an environmental attorney with at least ten (10) years experience in environmental matters involving oil and gas producing properties in the regional area in which the affected Assets are located, as selected by mutual agreement of Buyer and Seller within fifteen (15) days after the Closing Date, and absent such agreement, by the Denver, Colorado office of the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be held in Denver, Colorado and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section 12.1. The Environmental Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making its determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 12.1 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award Buyer its share of any greater Remediation Amount than the Remediation Amount claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price pursuant to Section 3.5 or Section 3.7, then, within ten (10) days after the Environmental Arbitrator delivers written notice to Buyer and Seller of his award with respect to any Remediation Amount, and subject to Section 12.1(d) (i) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Arbitrator to Seller, and (ii) Seller shall pay to Buyer the amount, if any, so awarded by the Environmental Arbitrator to Buyer. Nothing herein shall operate to cause Closing to be delayed on account of any arbitration conducted pursuant to this Section 12.1(e), and to the extent any adjustments are not agreed upon by the Parties as of Closing, the Purchase Price shall not be adjusted therefor at Closing and subsequent adjustments to the Purchase Price, if any, will be made pursuant to Section 3.7 or this Section 12.1(e).

12.2 NORM, Wastes and Other Substances. Buyer acknowledges that the Assets have been used for exploration, development, and production of oil and gas and that there may be petroleum, produced water, wastes or other substances or materials located in, on or under the Assets or associated with the Assets. Equipment and sites included in the Assets may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of wells, materials and equipment as scale, or in other forms. The wells, materials and equipment located on the Assets or included in the Assets may contain NORM and other wastes or Hazardous Substances. NORM containing material and/or other wastes or Hazardous Substances may have come in contact with various environmental media, including, water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation, or disposal of environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Assets.

BUYER AND SELLER ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

13.6 Exclusive Remedy. Notwithstanding anything to the contrary contained in this Agreement, the Parties agree that, from and after Closing, Section 6.6, Section 10.1(c), Section 11.1(c), Section 13.2 and Section 13.3, contain the Parties’ exclusive remedies against each other with respect to the transactions contemplated hereby, including breaches of the representations, warranties, covenants and agreements of the Parties contained in this Agreement or in any document or certificate delivered pursuant to this Agreement. Except as specified in Section 11.1(c) and Section 13.2, effective as of Closing, Buyer, on its own behalf and on behalf of the Buyer Indemnified Parties, hereby releases, remises and forever discharges Seller and its Affiliates and all such Persons’ equityholders, partners, members, directors, officers, employees, agents and representatives 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 Buyer or the Buyer Indemnified Parties might now or subsequently may have, based on, relating to or arising out of this Agreement, the transactions contemplated by this Agreement, the ownership, use or operation of any of the Assets prior to Closing or the condition, quality, status or nature of any of the Assets prior to Closing, including rights to contribution under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, breaches of statutory or implied warranties, nuisance or other tort actions, rights to punitive damages, common Law rights of contribution and rights under insurance maintained by Seller or any of its Affiliates (except as provided in Section 11.3(b)).

13.7 Indemnification Procedures. All claims for indemnification under Section 6.6, Section 10.1(c), Section 13.2 and Section 13.3 shall be asserted and resolved as follows:

(a) For purposes of Section 6.6, Section 10.1(c) and this Article XIII, the term “Indemnifying Party” when used in connection with particular Liabilities shall mean the Party or Parties having an obligation to indemnify another Party or Parties with respect to such Liabilities pursuant to Section 6.6, Section 10.1(c) or this Article XIII, and the term “Indemnified Party” when used in connection with particular Liabilities shall mean the Party or Parties having the right to be indemnified with respect to such Liabilities by another Party or Parties pursuant to Section 6.6, Section 10.1(c) or this Article XIII.

(b) To make claim for indemnification under Section 6.6, Section 10.1(c), Section 13.2 and Section 13.3, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 13.7, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Third Party Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 13.7(b) shall not relieve the Indemnifying Party of its obligations under Section 6.6, Section 10.1(c), Section 13.2 and Section 13.3 (as applicable) except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party's ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Third Party Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its liability to defend the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party admits its liability to defend the Indemnified Party against a Third Party Claim, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Indemnified Party against such Third Party Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 13.7(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Party does not admit its liability or admits its liability to defend the Indemnified Party against a Third Party Claim, but fails to diligently prosecute, indemnify against or settle the Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability and assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its liability to defend the Indemnified Party against a Third Party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its liability to indemnify the Indemnified Party from and against the liability and consent to such settlement and (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement, or (iii) deny liability. Any failure to respond such notice by the Indemnified Party shall be deemed to be an election under subsection (i) above.

(f) In the case of a claim for indemnification not based upon a Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to (i) cure the Liabilities complained of, (ii) admit its liability for such Liability or (iii) dispute the claim for such Liabilities. If the Indemnifying Party does not notify the Indemnified Party within such thirty (30) day period that it has cured the Liabilities or that it disputes the claim for such Liabilities, the amount of such Liabilities shall conclusively be deemed a liability of the Indemnifying Party hereunder.

(g) An Indemnified Party shall use reasonable commercial efforts to pursue, and to cause its Affiliates to pursue, all insurance claims to which it may be entitled in connection with any Liabilities for which a claim for indemnification is made, and the Parties shall cooperate with each other in pursuing insurance claims with respect to any such Liabilities or any indemnification obligations from Third Parties with respect to any such Liabilities. The Indemnifying Party is authorized by the Indemnified Party to give direction to the insurer under any insurance policy with respect to the defense of any action, suit, proceeding or claim relating to any liability giving rise to a claim for indemnification. If the Indemnifying Party makes any payment on any Third Party Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims of the Indemnified Party with respect to such Third Party Claim. The Parties acknowledge and agree that (i) the obligations of the Indemnified Party set forth in this Section 13.7(g) with respect to any Liabilities for which a claim for indemnification has been made shall be contingent on the Indemnified Party receiving a written statement from the Indemnifying Party whereby the Indemnifying Party admits its liability for such Liability and (ii) neither Party shall be required to maintain any particular insurance coverage following the Closing.

13.8 Survival.

(a) The representations and warranties of the Parties in Article IV and Article V (other than the representations and warranties in Sections 4.1, 4.2, 4.16, 5.1, 5.2, 5.9, 5.10 and 5.11), and the covenants and agreements of the Parties in Sections 6.1 and 9.4, shall survive Closing for a period of twelve (12) months. The representation and warranty of Seller in Section 11.1(b) shall terminate as of the expiration of the Survival Period. Subject to the foregoing and Section 13.8(b), the remainder of this Agreement (including Sections 4.1, 4.2, 4.6, 4.16, 5.1, 5.2, 5.9, 5.10 and 5.11) shall survive Closing without time limit. 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 asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b) The indemnities in Section 13.2(a), Section 13.2(b), Section 13.3(a) and Section 13.3(b) shall terminate as of the expiration date of each respective representation, warranty, covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Party on or before such expiration date. Seller’s indemnity in Section 13.2(c) shall survive without time limit and Seller’s indemnities in Section 13.2(d), Section 13.2(e) and Section 13.2(f) shall survive the Closing for a period of two (2) years. Buyer’s indemnities in Section 6.6, Section 10.1(c) and in Section 13.3(c) shall survive Closing without time limit and shall be deemed covenants running with the Assets (provided that Buyer and its successors and assigns shall not be released from any of, and shall remain jointly and severally liable to the Seller Indemnified Parties for, the obligations and Liabilities of Buyer under such Sections of this Agreement upon any transfer or assignment of any Asset).

13.9 Waiver of Right to Rescission. Seller and Buyer acknowledge that, following Closing, the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated by this Agreement. As the payment of money shall be adequate compensation, following Closing, Buyer and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.

13.10 Insurance, Taxes. The amount of any Liabilities for which any of the Indemnified Parties is entitled to indemnification under this Agreement or in connection with or with respect to the transactions contemplated by this Agreement shall be reduced by any corresponding (a) Tax benefit created or generated by the incurrence of the Liability or (b) insurance proceeds, from insurance policies carried by a party realized, or that could reasonably be expected to be realized by such Party if a claim were properly pursued under the relevant insurance arrangements.

13.11 Non-Compensatory Damages. None of the Buyer Indemnified Parties nor Seller Indemnified Parties shall be entitled to recover from Seller or Buyer, or their respective Affiliates, any special, indirect, consequential, punitive, exemplary, remote or speculative damages, including damages for lost profits of any kind arising under or in connection with this Agreement or the transactions contemplated hereby, except to the extent any such Party suffers such damages to a Third Party, which damages (including costs of defense and reasonable attorneys’ fees incurred in connection with defending against such damages) shall not be excluded by this provision as to recovery hereunder. Subject to the preceding sentence, Buyer, on behalf of each of the Buyer Indemnified Parties, and Seller, on behalf of each of Seller Indemnified Parties, waive any right to recover any special, indirect, consequential, punitive, exemplary, remote or speculative damages, including damages for lost profits of any kind, arising in connection with or with respect to this Agreement or the transactions contemplated hereby.

13.12 Cooperation by Buyer - Retained Litigation. Buyer agrees to use reasonable efforts to cooperate with Seller in connection with Seller’s defense and other actions relating to or arising out of the litigation and claims set forth in Schedule 13.1. Buyer agrees to make available Buyer’s employees engaged in the operation of the Assets for the purposes of providing testimony, depositions, information and other related activities relating to such litigation and claims.

13.13 Disclaimer of Application of Anti-Indemnity Statutes. The Parties acknowledge and agree that the provisions of any anti-indemnity statute relating to oilfield services and associated activities shall not be applicable to this Agreement and/or the transactions contemplated hereby.
