If the First Closing occurs, an amount equal to (i) the Deposit minus (ii) the Second Closing Base Purchase Price (the “First Closing Deposit Amount”) shall be released from the Deposit Escrow Account and applied toward the First Closing Amount under Section 3.4(b)(i), and the remaining amount of the Deposit (equal to the Second Closing Base Purchase Price) shall remain in the Deposit Escrow Account until the Second Closing occurs or the Agreement is terminated. If the Second Closing occurs, then the remainder of the Deposit shall be applied toward the Second Closing Amount under Section 3.4(b)(ii)(B). If either the First Closing or the Second Closing does not occur, the then remaining portion of the Deposit shall be released as provided in Section 12.2.

(A)          an amount equal to the following (the “Second Closing Payment”):  (1) the Second Closing Amount; minus (2) the then-remaining balance of the Deposit, shall be paid by Purchaser to Seller by federal funds wire transfer of immediately available funds to an account or accounts designated in writing by Seller to Purchaser; and

(B)          the Parties shall issue a joint written instruction to the Escrow Agent to release the remainder of the Deposit to Seller from the Deposit Escrow Account by federal funds wire transfer of immediately available funds to an account or accounts designated in writing by Seller to Purchaser;

provided, however, if the amount of the then-remaining balance of the Deposit exceeds the Second Closing Amount, then the Parties shall issue a joint written instruction to the Escrow Agent to (i) release an amount equal to the Second Closing Amount to Seller from the Deposit Escrow Account by federal funds wire transfer of immediately available funds to an account or accounts designated in writing by Seller to Purchaser, and (ii) release the remaining funds in the Deposit Escrow Account to Purchaser by federal funds wire transfer of immediately available funds to an account or accounts designated in writing by Purchaser to Seller.

(a)           in determining the Title Defect Value, the reduction in the Asset’s value shall be based on the Allocated Value as of the Execution Date;

(b)           the Title Defect Value shall not exceed the cost to cure the related Title Defect (if the cost to cure is reasonably determinable);

(c)           the aggregate amount of Title Defect Values attributable to all Title Defects affecting an Asset shall not exceed the Allocated Value of such Asset;

(d)           subject to the foregoing, if a Title Defect is a lien, encumbrance, or other charge which is undisputed and liquidated in amount, the Title Defect Value shall be the amount necessary to be paid to remove the lien;

(e)           if a Title Defect affects an Asset for less than its full productive life, the Title Defect Value shall be reduced to take into account only the applicable time period, using generally accepted engineering analysis and present value calculations;

(f)            the Title Defect Value attributable to any Title Defect shall not include any amount with respect to which Purchaser receives credit in the calculation of the Purchase Price attributable to any other Title Defect;

19

(g)           in determining any Title Defect Value as to any individual Title Defect or Acquired Asset, such Title Defect Value shall be without duplication of any other Title Defect Value calculated hereunder with respect to such Acquired Asset based on or arising out of the same underlying objections to title of Seller; and

(h)           Subject to Sections 5.4(a) through (g) above, if a Title Defect as to any Acquired Asset represents:

(i)            a negative discrepancy between the actual Net Revenue Interest for any Acquired Lease and the “Net Revenue Interest” percentage stated on Exhibit A-1 for such Acquired Lease, then the Title Defect Value shall be equal to the product of (A) the Net Mineral Acre Price thereof, multiplied by (B) the number of Net Mineral Acres of such Acquired Lease subject to such Title Defect, multiplied by (C) a fraction, the numerator of which is (1) the remainder of (x) the Net Revenue Interest stated in Exhibit A-1 for such Acquired Lease minus (y) the actual Net Revenue Interest for such Acquired Lease after giving effect to such Title Defect and the denominator of which is (2) the Net Revenue Interest stated in Exhibit A-1 for such Acquired Lease;

(ii)           a negative discrepancy between the actual Net Revenue Interest for any First Closing Well or Second Closing Well and the “Net Revenue Interest” percentage stated on Exhibit A-2 for such well, then the Title Defect Value shall be equal to the product of (A) the Allocated Value of such well, multiplied by (B) a fraction, the numerator of which is (1) the remainder of (x) the Net Revenue Interest stated in Exhibit A-2 for such well minus (y) the actual Net Revenue Interest for such well after giving effect to such Title Defect, and the denominator of which is (2) the Net Revenue Interest stated in Exhibit A-2 for such well; and

(iii)          a reduction in the number of Net Mineral Acres as to any Acquired Lease (or portion thereof), then the Title Defect Value for such Title Defect shall be equal to the product of (A) the Net Mineral Acre Price therefore multiplied by (B) the remainder of (1) the number of Net Mineral Acres purported to be included in such Acquired Lease as set forth on Exhibit A-1 minus (2) the actual number of Net Mineral Acres included in such Acquired Lease after giving effect to such Title Defect.

5.5  Title Defects Notices.

(a)           As a condition to asserting any claim with respect to any alleged Title Defect, Purchaser must deliver to Seller one or more valid written notices as to alleged Title Defects (each, a “Notice of Title Defects”) no later than (i) 5:00 p.m., Denver, Colorado time, on June 1, 2016, (the “Defect Notice Deadline”) with respect to First Closing Assets, and (ii) the Second Defect Notice Deadline, with respect to Second Closing Assets; provided that Purchaser agrees to provide Seller with periodic (but in no event less frequently than once every week) updates in writing concerning the progress of Purchaser’s title due diligence. Other than with respect to Purchaser’s title due diligence prior to the Defect Notice Deadline, Purchaser’s title due diligence with respect to the Second Closing Assets shall only take place during the Second Defect Review Period.

(b)           Such Notices of Title Defects, when considered together, set forth all Title Defects affecting the Assets that Purchaser desires to assert under this Agreement and all Interest Additions discovered by Purchaser or of which Purchaser has been notified under Section 5.8.  Each Notice of Title Defects shall, to the extent reasonably practicable, with respect to each such Title Defect or Interest Addition set forth therein: (i) describe such Title Defect or Interest

20

Addition and the Assets affected thereby; (ii) describe the basis of such Title Defect or Interest Addition; (iii) include documentation supporting the basis of such Title Defect or Interest Addition; (iv) in the case of a Title Defect, describe in general terms the curative actions that Purchaser reasonably anticipates are required to cure such Title Defect; (v) in the case of each Title Defect, describe Purchaser’s good faith estimate of the Title Defect Value with respect to each Asset affected by such Title Defect in accordance with and subject to the limitations in Section 5.4 (“Purchaser’s Title Defect Value”); and (vi) in the case of each Interest Addition, describe Purchaser’s good faith estimate of the value of such Interest Addition.

5.6          Waiver; Cure; Adjustment; Deductible.

(a)           Waiver. Without limitation of Purchaser’s rights under the special warranty of title in the Assignment, a Title Defect shall be and is hereby conclusively waived by Purchaser, Purchaser shall not be entitled to any adjustment for such Title Defect or to exclude the Asset affected by such Title Defect, and Seller shall not be obligated to cure such Title Defect, if: (i) Purchaser fails to provide a valid Notice of Title Defect to Seller of such Title Defect in accordance with Section 5.5(a) on or before the Defect Notice Deadline or the Second Defect Notice Deadline, as applicable; (ii) the Title Defect Value with respect to such Title Defect is less than the Title Defect Threshold; or (iii) the Allocated Value of the Asset affected by such Title Defect is less than the Title Defect Threshold.

(b)           Cure. Seller shall have the right and option, but not the obligation, to attempt to cure and to cure any Title Defects that are not waived under Section 5.6(a) (i) with respect to the First Closing Assets on or before the date thirty (30) days after the First Closing Date, and (ii) with respect to the Second Closing Assets on or before the Second Closing Date. Except in the case that Seller and Purchaser agree under Section 5.7 on the Title Defect Values for all Open Title Defects (excluding those that have been waived or previously cured under this Section 5.6), then Seller shall have an additional period from until (x) the First Closing Settlement Date to attempt to cure and to cure any such Title Defects with respect to the First Closing Assets and (y) the Second Closing Settlement Date to attempt to cure and to cure any such Title Defects with respect to the Second Closing Assets. A Title Defect that is not waived under Section 5.6(a) or cured under this Section 5.6(b) in accordance with the time limitations set forth in this Section 5.6(b) is referred to in this Agreement as a “Surviving Title Defect.” With respect to any Title Defect occurring as a result of Seller being entitled to less than the Net Revenue Interest set forth in Exhibit C for a specific Asset, the Parties agree that NBL Energy Royalties, Inc. may cure such Title Defect by conveying an valid override to Purchaser in an amount equal to the Net Revenue Interest discrepancy for such Asset.

(c)           Adjustment; Deductible. Purchaser shall be entitled to a downward adjustment to (i) the First Closing Base Purchase Price by the Defect Adjustment, if any, with respect to the First Closing Assets and (ii) the Second Closing Base Purchase Price by the Defect Adjustment, if any, with respect to the Second Closing Assets. The “Defect Adjustment” shall be the amount by which:  (x) the difference of the following (the “Net Aggregate Defect Value”): (A) the sum of the Title Defect Values with respect to all Surviving Title Defects minus the sum of the value of all Interest Additions (in the event the amount of (A) is less than zero, then (A) shall be deemed to be zero), plus (B) the sum of all Environmental Defect Values with respect to all Surviving Environmental Defects; exceeds (y) the Defect Deductible. If, after taking into account the provisions of this Article 5 and Article 6, the Defect Deductible is equal to or greater than the Net Aggregate Defect Value, then Purchaser shall not be entitled to a Defect Adjustment. For the avoidance of doubt, the Net Aggregate Defect Value shall be determined by taking into account Title Defects and Environmental Defects related to both the First Closing Assets and Second

21

Closing Assets on a cumulative basis. In no event shall any Acquired Assets be excluded from the Contemplated Transactions arising out of or relating to any Title Defects

5.7          Agreement on Title Defects and Interest Additions.

(a)           Attempt to Agree. With respect to each Title Defect that the Parties do not agree has been waived or cured under Section 5.6 (each, an “Open Title Defect”) and each Interest Addition, from the receipt by Seller of Purchaser’s Notice of Title Defects until (i) the First Closing Settlement Date with respect to the First Closing Assets and (ii) the Second Closing Settlement Date with respect to the Second Closing Assets, or the earlier acknowledgement of Purchaser in writing that it is not entitled to a Defect Adjustment, Purchaser and Seller shall attempt in good faith to agree on the existence and associated Title Defect Value of each such Open Title Defect, and the existence and associated value of each such Interest Addition.

(b)           Agreement. If Seller and Purchaser agree on the existence and Title Defect Value of any such Open Title Defect, then the Title Defect Value for such Open Title Defect shall be the agreed Title Defect Value for purposes of determining the Defect Adjustment, if any. If Seller and Purchaser agree on the existence and value of any Interest Addition, then the value of such Interest Addition shall be the agreed upon value for purposes of determining the Defect Adjustment, if any. Upon any such agreement, Seller and Purchaser shall execute a written instrument reflecting such agreement.

(c)           Agreement Before Closing. If, before the First Closing Date, Seller and Purchaser agree on (i) the existence and Title Defect Values of all Open Title Defects with respect to the First Closing Assets, (ii) the existence and value of all Interest Additions with respect to the First Closing Assets and (iii) the existence and Environmental Defect Values of all Open Environmental Defects with respect to the First Closing Assets, then the amount of the Defect Adjustment, if any, shall be deducted from the First Closing Base Purchase Price at the First Closing, and shall be reflected in the First Closing Amount. If, before the Second Closing Date, Seller and Purchaser agree on (i) the existence and Title Defect Values of all Open Title Defects with respect to the Second Closing Assets, (ii) the existence and value of all Interest Additions with respect to the Second Closing Assets and (iii) the existence and Environmental Defect Values of all Open Environmental Defects with respect to the Second Closing Assets, then the amount of the Defect Adjustment, if any, shall be deducted from the Second Closing Base Purchase Price at the Second Closing, and shall be reflected in the Second Closing Amount.

(d)           Failure to Agree. If, (i) before the First Closing Date, Seller and Purchaser do not agree on the existence and Title Defect Values of all Open Title Defects with respect to the First Closing Assets, and the existence and value of all Interest Additions with respect to the First Closing Assets, or (ii) before the Second Closing Date, Seller and Purchaser do not agree on the existence and Title Defect Values of all Open Title Defects with respect to the Second Closing Assets, and the existence and value of all Interest Additions with respect to the Second Closing Assets then:  (x) the existence and Title Defect Value of those Open Title Defects that are not agreed (but only those that are not agreed), and the existence and value of those Interest Additions that are not agreed (but only those that are not agreed), shall be Title Disputed Matters settled by the Title Expert under Section 5.9; (y) there shall be no adjustment to the First Closing Amount or Second Closing Amount, as applicable, or exclusion of Assets for any such Open Title Defects or Interest Additions; and (z) the First Closing Base Purchase Price or Second Closing Base Purchase Price, as applicable, shall be adjusted downward pursuant to the final settlement under Section 14.1 by the amount of the Defect Adjustment, if any, based on the Title Defect Values of any Surviving Title Defects, and the values of any Interest Additions, in each case

22

determined under this Section 5.7 or Section 5.9, as applicable; provided, however, that any such Surviving Title Defects that are cured by Seller under Section 5.6(b), as applicable, shall not be considered Surviving Title Defects and shall be and are hereby waived.

5.8          Interest Additions.

(a)           Notice of Interest Additions. If Purchaser or Seller discovers any additional interests in the Assets that are not listed in Exhibit A, including any interest that entitles Seller to receive more than the Net Revenue Interest with respect to any such Asset set forth in Exhibit A-2, or obligates Seller to bear costs and expenses in an amount less than the Working Interest with respect to any such Asset set forth in Exhibit A-2, and assuming no corresponding reduction in the Net Revenue Interest (each an “Interest Addition”), the discovering Party shall promptly after discovery (but in any event before the Defect Notice Deadline or the Second Defect Notice Deadline, as applicable), provide written notice to the other Party of such Interest Addition. Such notice shall be in writing and shall include:  (i) a description of each such Interest Addition; (ii) the basis for each such Interest Addition, and supporting documentation with respect thereto; (iii) the Assets and the Allocated Value of the Assets affected by each such Interest Addition; and (iv) the value of the Interest Addition or the amount by which the notifying Party reasonably believes the Allocated Value of the affected Assets should be increased by the Interest Addition, and the computations upon which and Party belief is based.

(b)           Effect of Interest Additions. There shall be no increase to the First Base Purchase Price or Second Base Purchase Price as a result of any Interest Additions. Interest Additions shall be offset against Title Defect Values in determining the Defect Adjustment, if any, as provided in Section 5.6(c). An Interest Addition need not be contained in Purchaser’s Notice of Title Defects to be taken into account; provided, however, that an Interest Addition shall only be taken into account if Purchaser has notice or actual knowledge of such Interest Addition before the Defect Notice Deadline or the Second Defect Notice Deadline, as applicable.

5.9          Dispute Resolution. If (1) any Open Title Defects, including the existence, waiver, cure, and Title Defect Values thereof, or any Interest Additions, including the existence and values thereof (collectively, “Title Disputed Matters”), are not agreed upon under Section 5.7 and neither Party has elected to terminate under Section 6.7, then any such Title Disputed Matters or (2) Purchaser timely delivers a Purchaser Defect Termination Notice and Seller delivers a Termination Dispute Notice, then any Unagreed Termination Title Matters, shall, in each case be resolved by a single Title Expert under the dispute resolution procedure in this Section 5.9.

(a)           Selection of Expert. Seller and Purchaser shall act in good faith to promptly execute such engagement letters and other documents as shall be necessary to engage the Title Expert within thirty (30) Business Days after the First Closing or Second Closing, as applicable, (or in the case of a Termination Dispute Notice, within thirty (30) Business Days after the delivery by Seller of such Termination Dispute Notice). After the Title Expert has been engaged, if the Title Expert withdraws after a challenge, dies, or otherwise resigns or is removed, then such Title Expert shall be replaced within five (5) Business Days thereafter by Purchaser and Seller in accordance with this Section 5.9, and the time periods in this Section 5.9 shall be extended as necessary or appropriate. The fees and expenses of the Title Expert shall be paid fifty percent (50%) by Seller and fifty percent (50%) by Purchaser.

(b)           Materials to Title Expert. Within forty five (45) Business Days after the First Closing Date or Second Closing Date, as applicable, (or in the case of a Termination Dispute Notice, within twenty (20) Business Days after the delivery by Seller of such Termination Dispute Notice), the Parties shall provide to the Title Expert the following materials:

23

(i)            Purchaser’s Notice of Title Defects and all documentation provided therewith and such evidence as Purchaser deems appropriate to validate the existence, and alleged Title Defect Values with respect to all Open Title Defects, and the Interest Additions and values with respect thereto (or in the case of a Termination Dispute Notice, Unagreed Termination Title Matters), in each case assigned thereto by Purchaser in its Notice of Title Defects, together with Purchaser’s good faith estimate of the values with respect to all such Interest Additions identified by Seller, if any (or in the case of a Termination Dispute Notice, Unagreed Termination Title Matters);

(ii)           such evidence as Seller deems appropriate to dispute the existence, waiver, cure, and alleged Title Defect Values with respect to all Open Title Defects, and the Interest Additions and values with respect thereto (or in the case of a Termination Dispute Notice, Unagreed Termination Title Matters), in each case assigned thereto by Purchaser in its Notice of Title Defects, together with Seller’s good faith estimate of the Title Defect Values with respect to all such Open Title Defects, if any, and the values with respect to all such Interest Additions identified by Purchaser, if any (or in the case of a Termination Dispute Notice, Unagreed Termination Title Matters); and

(iii)          this Article 5, and Exhibits A-1, A-2, A-3, A-4, A-5, and C to this Agreement, together with any definitions of terms used in this Article 5 and such Exhibits, but no other provisions of this Agreement.

(c)           Decisions of Title Expert. The Title Expert shall make his or her determination and provide to the Parties written findings within twenty (20) Business Days after he has received the materials under Section 5.9(b). The decision of the Title Expert shall be final and non-appealable and shall be limited to awarding only Seller’s position or Purchaser’s position with respect to the Title Disputed Matters associated with each Open Title Defect and Interest Addition (or in the case of a Termination Dispute Notice, each Unagreed Termination Title Matter), in each case that are not agreed upon by the Parties under Section 5.7 or Section 6.7, as applicable. The Title Expert shall make a separate determination with respect to each Open Title Defect and Interest Addition (or in the case of a Termination Dispute Notice, each Unagreed Termination Title Matter). The written finding of the Title Expert shall only set forth the Title Expert’s decision with respect to each applicable Open Title Defect and Interest Addition (or in the case of a Termination Dispute Notice, each Unagreed Termination Title Matter), and not the Title Expert’s rationale for the decision. The Title Expert shall not make any other award or grant any other remedy, whether or not prohibited or contemplated by this Agreement, and shall certify, as necessary, the resolution of such Title Disputed Matters (or in the case of a Termination Dispute Notice, such Unagreed Termination Title Matters), as applicable, to the Accounting Referee under Section 14.1.

5.10        Special Warranty of Title in the Assignments.

(a)           Each Assignment delivered at each applicable Closing will contain a special warranty of Defensible Title whereby Seller shall warrant Defensible Title to its interest in the applicable Acquired Properties assigned thereunder unto Purchaser against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller but not otherwise, subject, however, to the Permitted Liens.  The special warranty of Defensible Title contained in each Assignment shall be subject to the further limitations and provisions of this Article 5, mutatis mutandis, including the Title Defect Threshold and the Defect Deductible.

24

(b)           No later than the date twelve (12) months after the applicable Closing Date, Purchaser may furnish Seller a Notice of Title Defect meeting the requirements of Section 5.5(a) setting forth any matters which Purchaser asserts as a breach of the special warranty of Defensible Title set forth in the Assignment delivered at such Closing.  Seller shall have a reasonable opportunity, but not the obligation, to cure prior to the Final Settlement Date any alleged breach of such special warranty of Defensible Title pursuant to Section 5.6(b).  Purchaser shall be deemed to have waived all breaches of Seller’s special warranty of Defensible Title set forth in any Assignment for which Seller has not received on or before the date twelve (12) months after the applicable Closing Date such Assignment was delivered a valid Notice of Title Defects that satisfies the requirements set forth in Section 5.5(a).

(c)           For purposes of the special warranty of Defensible Title contained in any Assignment, the value of the Acquired Assets set forth in the exhibits thereto, as applicable, shall be deemed to be the Allocated Value thereof, as adjusted herein.  Recovery on the special warranty of Defensible Title contained in any Assignment shall be limited to an amount (without any interest accruing thereon) equal to the reduction in the Second Closing Base Purchase Price to which Purchaser would have been entitled had Purchaser asserted the Title Defect giving rise to such breach of the special warranty of Defensible Title contained in such Assignment, as a Title Defect prior to the Defect Notice Deadline or the Second Defect Notice Deadline, as applicable, pursuant to Section 5.5, in each case without regard to the Title Defect Threshold or the Defect Deductible.

5.11        Changes in Prices; Well Events. Purchaser shall assume all risk of Loss with respect to: (a) changes in commodity or product prices and any other market factors or conditions from and after April 1, 2016; (b) production declines or any adverse change in the production characteristics or downhole condition of an Acquired Well, including any Acquired Well watering out, or experiencing a collapse in the casing or sand infiltration, from and after April 1, 2016; and (c) depreciation of any Acquired Assets that constitute personal property through ordinary wear and tear, and none of the foregoing shall constitute Title Defects or otherwise give rise to any Claims by Purchaser before, on, or after any Closing.

5.12        Exclusive Remedy. EXCEPT FOR THE SPECIAL WARRANTY OF TITLE IN THE ASSIGNMENTS, THIS Article 5 SHALL, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BE THE EXCLUSIVE RIGHT AND REMEDY OF PURCHASER WITH RESPECT TO TITLE DEFECTS AND OTHER DEFICIENCIES IN TITLE WITH RESPECT TO THE ACQUIRED ASSETS.  EXCEPT FOR THE SPECIAL WARRANTY OF TITLE IN THE ASSIGNMENTS AND AS PROVIDED IN THIS Article 5, PURCHASER RELEASES, REMISES, AND FOREVER DISCHARGES SELLER AND ITS AFFILIATES AND ITS AND THEIR RESPECTIVE STOCKHOLDERS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, ADVISORS, 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 PURCHASER MIGHT NOW OR SUBSEQUENTLY MAY HAVE, BASED ON, RELATING TO OR ARISING OUT OF, ANY TITLE DEFECT OR OTHER DEFICIENCY IN TITLE TO ANY ASSET.  NOTWITHSTANDING ANYTHING HEREIN OR ANY TRANSACTION DOCUMENT TO THE CONTRARY, IN NO EVENT DOES SELLER MAKE ANY REPRESENTATION OR WARRANTY WITH RESPECT TO THE EASEMENTS EXCEPT FOR THE SPECIAL WARRANTY OF DEFENSIBLE TITLE SET FORTH IN THE ASSIGNMENTS.

25

Article 6
Environmental Matters

6.1          Environmental Investigation.

(a)           Environmental Reports and Personnel. Subject to Section 4.1(b), and (i) until the Defect Notice Deadline, with respect to Purchaser’s environmental due diligence regarding the First Closing Assets, and (ii) during the Second Defect Review Period with respect to Purchaser’s environmental due diligence regarding the Second Closing Assets, Seller shall provide Purchaser with access during the regular business hours of Seller to all information in Seller’s possession or control pertaining to the Environmental Condition of the Acquired Assets, including any environmental reports, Permits, Records, notices of violation from the Governmental Authorities,  and assessments, and shall use Commercially Reasonable Efforts (but in no event required to make any payments or incur any material obligations owed to any Person) to make available to Purchaser those Entity Representatives of Seller who would reasonably be expected to have material knowledge or material information regarding the environmental status or condition of the Acquired Assets.

(b)           Environmental Assessment.

(i)            Purchaser may, or may engage a qualified environmental contractor to, conduct Phase I Environmental Site Assessments in accordance with the American Society for Testing and Materials (A.S.T.M.) Standard Practice Environmental Site Assessments: Phase I Environmental Site Assessment Process (Publication Designation: E1527-05) of the Acquired Assets (an “Environmental Assessment”) at Purchaser’s sole risk, Liability, and expense; provided, however, that:  (i) Purchaser shall provide Seller with prior written notice of any activities with respect to any such Environmental Assessment, and shall provide Seller the opportunity to participate in all such activities; (ii) any contractor engaged to perform all or any portion of such Environmental Assessment shall execute and deliver to Seller a confidentiality agreement in a form acceptable to Seller acting reasonably; (iii) Purchaser shall not conduct, authorize, or permit any test drilling, sampling, or other on-site activities without prior written notice to Seller, and the prior written consent of Seller, which consent may be granted, conditioned or withheld at the sole discretion of Seller; and (iv) Purchaser shall provide to Seller promptly (and in any event, within three Business Days) after receipt, at no cost to Seller, all draft and final reports, results, data, analyses of site visits, Remediation cost estimates, and any other portion of such Environmental Assessment, all of which shall be subject to the confidentiality provisions in Section 10.13.  If the First Closing does not occur, Purchaser shall promptly return to Seller or destroy all copies of the records, reports, summaries, evaluations, due diligence memos and derivative materials related thereto in the possession or control of Purchaser or any of Purchaser’s Entity Representatives. If the Second Closing does not occur, Purchaser shall promptly return to Seller or destroy all copies of the records, reports, summaries, evaluations, due diligence memos and derivative materials related to the Second Closing Assets in the possession or control of Purchaser or any of Purchaser’s Entity Representatives. Any disturbance to the Assets (including the leasehold associated therewith) resulting from Purchaser’s due diligence will be promptly corrected by Purchaser.

(ii)           In the event that Purchaser’s Environmental Assessment identifies actual or potential “recognized environmental conditions” with respect to any Asset, then Purchaser may request in writing (“Phase II Request”) Seller’s permission to conduct a

26

Phase II Environmental Site Assessment to further assess such conditions.  Such Phase II Request will state with reasonable specificity (i) the actual or potential “recognized environmental conditions” identified and (ii) the proposed scope of the Phase II assessment, including a description of the activities to be conducted, and a description of the approximate location and expected timing of such activities.  Seller may, in its sole discretion, approve said Phase II assessment plan, in whole or in part, and Purchaser shall not have the right to conduct any activities set forth in such plan until such time that Seller has approved such plan in writing. Any such approved Phase II assessment plan shall be conducted by a reputable environmental consulting or engineering firm.  Seller shall have the right to (x) condition any approval of the Phase II assessment plan on the provision of proof of satisfactory insurance and (y) if said plan is approved by Seller, have its representatives witness all on-site activities set forth in such Phase II assessment plan and split any samples collected in connection therewith.  If Seller does not provide its consent to any Phase II Request delivered in accordance with the above terms within two (2) Business Days of Purchaser’s delivery of such request, then the affected Asset (or portion thereof) for which consent is not provided shall be excluded from the Assets to be conveyed at Closing, in which case, such Asset (or portion thereof so affected) shall become an Excluded Asset, and at Closing, the Allocated Value of all Assets excluded pursuant to this Section 6.1(b) shall be deducted from the Base Purchase Price and the Asset shall be deemed deleted from the Exhibits and Schedules hereto; provided, however that the removal of any such Asset pursuant to this Section 6.1(b) shall not be taken into account in determining whether the Title/Environmental Termination Threshold has been met or exceeded.

6.2          Environmental Defect. “Environmental Defect” means the failure of Seller’s ownership and operation of the Acquired Assets to be in material compliance as of 5:00 p.m., Denver, Colorado, time on April 1, 2016 with applicable Environmental Laws in effect as of the Execution Date, but excluding the following (which shall not constitute Environmental Defects): (x) any Plugging and Abandonment Obligations; (y) the presence or absence of naturally occurring radioactive material, radon gas and asbestos (“NORM”) in or on the Acquired Assets; and (z) any matter that is subject to or covered by the Consent Decree. An Environmental Defect may only be raised after the Defect Notice Deadline and during the Second Defect Review Period if such Environmental Defect relates to a Second Closing Asset. An Environmental Defect may only be alleged after the Defect Notice Deadline and during the Second Defect Review Period if such Environmental Defect relates to a Second Closing Asset. Environmental Defects relating to Second Closing Assets may only be alleged during the Second Defect Review Period.

6.3          Environmental Defect Value. “Environmental Defect Value” means, with respect to an Environmental Defect, the amount equal to the estimated costs and expenses of Seller (based on the reasonable proportionate cost to Seller) that would be incurred by Seller to Remediate or otherwise cure such Environmental Defect in the lowest cost manner reasonably available, (x) consistent with applicable Environmental Laws, taking into account (i) the nature of the Environmental Defect, (ii) the likelihood that such Environmental Defect actually will result in a Claim or Liability by any Governmental Authority or any other third-party, (iii) any subsequent Remediation or cure of the Environmental Defect by Seller within the time frames permitted under this Agreement and (iv) that non-permanent remedies (including without limitation, mechanisms to contain or stabilize Hazardous Materials, including monitoring site conditions, natural attenuation, risk-based corrective action, institutional controls, or other appropriate restrictions on the industrial use of the property, caps, dikes, encapsulation, lechate collection systems, and the like) may be the lowest cost manner reasonably available and, (y) where applicable, to the satisfaction of the applicable Governmental Authorities.

27

6.4          Environmental Defect Notices.

(a)           As a condition to asserting any claim with respect to any alleged Environmental Defect, Purchaser must deliver to Seller a valid written Notice of Environmental Defect as to any alleged Environmental Defect no later than (i) the Defect Notice Deadline, with respect to First Closing Assets, and (ii) the Second Defect Notice Deadline, with respect to Second Closing Assets.

(b)           On or before the Defect Notice Deadline or Second Defect Notice Deadline, as applicable, for any alleged Environmental Defect, Purchaser shall deliver to Seller a valid written notice (a “Notice of Environmental Defects”) that sets forth all Environmental Defects affecting the Acquired Assets that Purchaser desires to assert under this Agreement.  In order to be valid, the Notice of Environmental Defects shall, with respect to each Environmental Defect set forth therein:  (i) describe the nature of and basis for such Environmental Defect; (ii) describe the specific Assets affected by such Environmental Defect; (iii) references to the specific provisions and sections of Environmental Laws that Seller or the Acquired Assets are in violation of or non-compliance with that forms the basis of such Environmental Defect; (iv) describe the Remediation or other curative action that Purchaser reasonably anticipates is required to Remediate or otherwise cure such Environmental Defect; (v) describe Purchaser’s good-faith estimate of the Environmental Defect Value with respect to each Acquired Asset affected by such Environmental Defect; and (vi) include all documentation supporting the nature and basis of such Environmental Defect and the estimate of its Environmental Defect Value.

6.5          Waiver; Remediation; Adjustment; Deductible.

(a)           Waiver. An Environmental Defect shall be and is hereby conclusively waived by Purchaser, Purchaser shall not be entitled to any remedies or adjustment for such Environmental Defect or to exclude the Acquired Asset affected by such Environmental Defect, and Seller shall not be obligated to cure such Environmental Defect, if: (i) Purchaser fails to provide written notice to Seller of such Environmental Defect in accordance with Section 6.4(b) on or before the Defect Notice Deadline or Second Defect Notice Deadline, as applicable, or (ii) the Environmental Defect Value with respect to such Environmental Defect is less than the Environmental Defect Threshold.  Except as specifically set forth in Section 6.1(b)(ii) and Section 6.5(d), in no event shall any Acquired Assets be excluded from the Contemplated Transactions arising out of or relating to any Environmental Defects.

(b)           Remediation. Seller shall have the right and option, but not the obligation, to attempt to Remediate or otherwise cure, and to Remediate or otherwise cure, any Environmental Defects that are not waived under Section  6.5(a) (i) with respect to the First Closing Assets on or before the date thirty (30) days after the First Closing Date, and (ii) with respect to the Second Closing Assets on or before the Second Closing Date. Except in the case that Seller and Purchaser agree under Section 6.6 on the Environmental Defect Values for all Open Environmental Defects (excluding those that have been waived or previously cured under this Section 6.5), then Seller shall have an additional period until the First Closing Settlement Date, with respect to First Closing Assets, and until the Second Closing Settlement Date, with respect to Second Closing Assets, to attempt to Remediate or otherwise cure, and to Remediate or otherwise cure, any such Environmental Defects. An Environmental Defect that is not waived under Section 6.5(a) or Remediated or otherwise cured under this Section 6.5(b) is referred to in this Agreement as a “Surviving Environmental Defect.”

(c)           Adjustment; Deductible. Purchaser shall be entitled to a downward adjustment to (i) the First Closing Base Purchase Price by the Defect Adjustment, if any, with respect to the

28

First Closing Assets and (ii) the Second Closing Base Purchase Price by the Defect Adjustment, if any, with respect to the Second Closing Assets as provided in Section 5.6(c). For the avoidance of doubt, the Defect Adjustment shall be determined by taking into account Environmental Defects related to both the First Closing Assets and Second Closing Assets on a cumulative basis.

(d)           Exclusion of Assets. In the event the Environmental Defect Value as determined by Purchaser in good faith and included in the applicable Notice of Environmental Defects for any Asset is equal to or exceeds the Allocated Value of such Asset, then either Party shall have the option to elect by written notice to the other Party no later than three (3) Business Days after the Defect Notice Deadline or Second Defect Notice Deadline, as applicable, to have the affected Asset (or portion thereof subject to the Environmental Defect) excluded from the Assets to be conveyed at Closing, in which case, such Asset (or portion thereof so affected) shall become an Excluded Asset, and at Closing, the Allocated Value of all Assets excluded pursuant to this Section 6.1(b) shall be deducted from the Base Purchase Price and the Asset shall be deemed deleted from the Exhibits and Schedules hereto; provided, however that the removal of any such Asset pursuant to this Section 6.5(d) shall not be taken into account in determining whether the Title/Environmental Termination Threshold has been met or exceeded.

6.6          Agreement on Environmental Defects.

(a)           Attempt to Agree. With respect to each Environmental Defect that the Parties do not agree has been waived or Remediated or otherwise cured under Section 6.5 (each, an “Open Environmental Defect”), from the receipt by Seller of Purchaser’s Notice of Environmental Defects until (i) the First Closing Settlement Date with respect to the First Closing Assets and (ii) the Second Closing Settlement Date with respect to the Second Closing Assets, or the earlier acknowledgement of Purchaser in writing that it is not entitled to a Defect Adjustment, Purchaser and Seller shall attempt in good faith to agree on the existence and associated Environmental Defect Value of each such Open Environmental Defect.

(b)           Agreement. If Seller and Purchaser agree on the existence and Environmental Defect Value of any such Open Environmental Defect, then the Environmental Defect Value for such Open Environmental Defect shall be the agreed Environmental Defect Value for purposes of determining the Defect Adjustment, if any. Upon any such agreement, Seller and Purchaser shall execute a written instrument reflecting such agreement.

(c)           Agreement Before Closing. If, before the First Closing Date, Seller and Purchaser agree on (i) the existence and Title Defect Values of all Open Title Defects with respect to the First Closing Assets, (ii) the existence and value of all Interest Additions with respect to the First Closing Assets and (iii) the existence and Environmental Defect Values of all Open Environmental Defects with respect to the First Closing Assets, then the amount of the Defect Adjustment, if any, shall be deducted from the First Closing Base Purchase Price at the First Closing, and shall be reflected in the First Closing Amount. If, before the Second Closing Date, Seller and Purchaser agree on (i) the existence and Title Defect Values of all Open Title Defects with respect to the Second Closing Assets, (ii) the existence and value of all Interest Additions with respect to the Second Closing Assets and (iii) the existence and Environmental Defect Values of all Open Environmental Defects with respect to the Second Closing Assets, then the amount of the Defect Adjustment, if any, shall be deducted from the Second Closing Base Purchase Price at the Second Closing, and shall be reflected in the Second Closing Amount.

(d)           Failure to Agree. If, (i) before the First Closing Date, Seller and Purchaser do not agree on the existence and Environmental Defect Values of all Open Environmental Defects with respect to the First Closing Assets, or (ii) before the Second Closing Date, Seller and Purchaser

29

do not agree on the existence and Environmental Defect Values of all Open Environmental Defects with respect to the Second Closing Assets, then: (x) the existence and Environmental Defect Value of those Open Environmental Defects that are not agreed (but only those that are not agreed), shall be Environmental Disputed Matters settled by the Environmental Expert under Section 6.8; (y) there shall be no adjustment to the First Closing Amount or Second Closing Amount, as applicable, or exclusion of any Acquired Assets for any such Open Environmental Defects; and (z) the First Closing Base Purchase Price or Second Closing Base Purchase Price, as applicable, shall be adjusted downward pursuant to the final settlement under Section 14.1 by the amount of the Defect Adjustment, if any, based on the Environmental Defect Values of any Surviving Environmental Defects, in each case determined under this Section 6.6 or Section 6.8, as applicable; provided, however, that any such Surviving Environmental Defects that are Remediated or otherwise cured by Seller under Section 6.5(b) before the First Closing Settlement Date or Second Closing Settlement Date, as applicable, shall not be considered Surviving Environmental Defects and shall be and are hereby waived.

6.7          Termination for Title/Environmental Defects.

(a)           If, (i) the sum of:  (A) the aggregate Title Defect Values alleged by Purchaser in good faith in all of its Notices of Title Defects with respect to all Title Defects alleged by Purchaser in good faith in such Notices of Title Defects; minus (B) the aggregate value of all Interest Additions alleged by Purchaser or Seller, in each case in good faith, in either Party’s notice of Interest Additions; plus (C) the aggregate Environmental Defect Values (affecting the First Closing Assets only) alleged by Purchaser in good faith in all of its Notices of Environmental Defects with respect to all Environmental Defects (affecting the First Closing Assets only) alleged by Purchaser in good faith in such Notices of Environmental Defects; exceeds (ii) an amount equal to twenty percent (20%) of the Base Purchase Price  (the amount in this clause (ii), the “Title/Environmental Termination Threshold”), then (x) Seller may send a written notice to Purchaser within five (5) Business Days after the Defect Notice Deadline indicating that Seller desires to terminate this Agreement, in which case this Agreement shall immediately terminate and the Deposit shall be released in accordance with Section 12.2, and (y) Purchaser may send a written notice to Seller (a “Purchaser Defect Termination Notice”) no later than three (3) Business Days after the Defect Notice Deadline that Purchaser desires to terminate this Agreement.  If no Party elects to terminate this Agreement under this Section 6.7, then all Title Defects and Environmental Defects shall be addressed in accordance with Section 5.9 or Section 6.8, as applicable. Any Purchaser Defect Termination Notice shall be based on alleged Title Defects, alleged Title Defect Values, alleged Interest Additions, alleged values of Interest Additions, alleged Environmental Defects, and alleged Environmental Defect Values that are reasonably determined in good faith by Purchaser or Seller, as applicable, at the time of such notice. For the avoidance of doubt, this Section 6.7 shall not apply to Title Defects or Environmental Defects alleged with respect to the Second Closing Assets and neither Seller nor Purchaser shall have any termination right with respect to such alleged Title Defects or Environmental Defects.

(b)           Within four (4) Business Days after the receipt by Seller of a Purchaser Defect Termination Notice, Seller shall send a written notice to Purchaser (a “Termination Response Notice”) indicating Seller’s election in its sole discretion to either:  (i) terminate this Agreement, in which case this Agreement shall immediately terminate and the Deposit shall be released in accordance with Section 12.2; or (ii) proceed to have any Title Defects alleged by Purchaser in its Notice of Title Defects, the existence, waiver, cure, or Title Defect Value of which are not agreed in good faith by Seller, and any Interest Additions, the existence or value of which are not agreed in good faith by Seller (collectively, “Unagreed Termination Title Matters”) determined under

30

Section 5.9, and any Environmental Defects alleged by Purchaser in its Notice of Environmental Defects, the existence, waiver, Remediation, or Environmental Defect Value of which are not agreed in good faith by Seller (“Unagreed Termination Environmental Matters”) determined under Section 6.8, as applicable. If Seller delivers a Termination Response Notice under clause (ii) of this Section 6.7(b) (a “Termination Dispute Notice”), then the Parties shall immediately proceed to have any Unagreed Termination Title Matters determined under Section 5.9, and any Unagreed Termination Environmental Matters determined under Section 6.8, as applicable, and the First Closing, Second Closing or termination, as applicable, of this Agreement shall be stayed (and the First Closing Date and the Second Closing Date shall be extended) pending the outcome of such dispute resolution procedures.

(c)           If Seller delivers a Termination Dispute Notice and after the determination under Section 5.9 of any such Unagreed Termination Title Matters, and the determination under Section 6.8 of any such Unagreed Termination Environmental Matters, as applicable, the sum of the Surviving Defects and the Surviving Environmental Defects exceeds the Title/Environmental Termination Threshold, then this Agreement shall immediately terminate and the Deposit shall be released in accordance with Section 12.2.

(d)           If Seller delivers a Termination Dispute Notice and after the determination under Section 5.9 of any Unagreed Termination Title Matters, and the determination under Section 6.8 of any Unagreed Termination Environmental Matters, as applicable, the sum of the Surviving Defects and the Surviving Environmental Defects does not exceed the Title/Environmental Termination Threshold, then the Parties shall, subject to the satisfaction or waiver of the other conditions to applicable Closings in this Agreement, immediately proceed to the applicable Closing(s).

6.8          Dispute Resolution. If (1) any Open Environmental Defects, including the existence, waiver, Remediation, and Environmental Defect Values thereof (collectively, “Environmental Disputed Matters”), are not agreed upon under Section 6.6, then any such Environmental Disputed Matters or (2) Purchaser timely delivers a Purchaser Defect Termination Notice and Seller delivers a Termination Dispute Notice, then any Unagreed Termination Environmental Matters, shall, in each case, be resolved by a single Environmental Expert under the dispute resolution procedure in this Section 6.8.

(a)           Selection of Expert. Seller and Purchaser shall act in good faith to promptly execute such engagement letters and other documents as shall be necessary to engage the Environmental Expert within five (5) Business Days after the First Closing or Second Closing, as applicable, (or in the case of a Termination Dispute Notice, within five (5) Business Days after the delivery by Seller of such Termination Dispute Notice). After the Environmental Expert has been engaged, if the Environmental Expert withdraws after a challenge, dies, or otherwise resigns or is removed, then such Environmental Expert shall be replaced within five (5) Business Days thereafter by Purchaser and Seller in accordance with this Section 6.8, and the time periods in this Section 6.8 shall be extended as necessary or appropriate. The fees and expenses of the Environmental Expert shall be paid fifty percent (50%) by Seller and fifty percent (50%) by Purchaser.

(b)           Materials to Environmental Expert. Within twenty (20) Business Days after the First Closing Date or Second Closing Date, as applicable, (or in the case of a Termination Dispute Notice, within twenty (20) Business Days after the delivery by Seller of such Termination Dispute Notice), the Parties shall provide to the Environmental Expert the following materials:

Notwithstanding anything to the contrary in this Agreement, this Article 6 and the indemnifications provided for under Section 16.2(a)(iii) constitute the entire and exclusive remedies of Purchaser with respect to any conditions, events, circumstances, acts, or omissions of, or relating to, the Environment, any Hazardous Materials, any Releases, or any Assumed Environmental Liabilities (collectively, “Environmental Matters”).  Subject to Article 16, Purchaser hereby waives, for itself and its successors and assigns, any other Claims, Losses, or rights against any of the Indemnified Seller Parties relating to any Environmental Matters, whether arising under Environmental Laws, any other Laws (whether in contract, tort, equity, or otherwise), or any other legal theory.

(a)                                 From and after the Execution Date until the applicable Closing, Seller shall use its Commercially Reasonable Efforts (but in no event required to make any payments or incur any material obligations owed to any Person), with reasonable assistance from Purchaser (including Purchaser providing required assurances of financial condition and operator qualifications), to obtain all Material Required Consents before such Closing.  Purchaser shall bear and be liable for, and the Assumed Liabilities shall include, any payments or obligations required under the terms of the concerned contract that are owed by any Party or Indemnified Seller Party to any Person other than a Party in connection with obtaining any Material Required Consents or other consents.

(b)                                 If, during the course of Purchaser’s Due Diligence Review, Purchaser discovers any Material Required Consent that is not listed in Section 8.1 of the Disclosure Schedule, Purchaser shall promptly after discovery give written notice to Seller of such Material Required Consent, and Section 8.1 of the Disclosure Schedule shall be deemed updated by the Material Required Consent. Notwithstanding anything to the contrary in this Agreement, the failure to obtain a Material Required Consent before the applicable Closing shall not constitute a breach of any representation, warranty, or covenant in this Agreement.

(c)                                  If a Material Required Consent is not obtained before the applicable Closing: (i) until the Final Settlement Date, Seller and Purchaser shall work together in good faith to obtain such Material Required Consent (including, in the case of Purchaser, providing reasonable or required assurance of financial condition and operator qualifications); (ii) neither this Agreement nor any other Transaction Document shall constitute an actual or attempted sale, assignment, assumption, transfer, conveyance, or delivery of the Acquired Assets or Assumed Liabilities subject to the Material Required Consent; (iii) until any such Material Required Consent is obtained, the Parties shall cooperate with each other in any reasonable and lawful arrangements designed to provide to Purchaser the benefits of the Acquired Assets and the burdens of the Assumed Liabilities subject to the Material Required Consent; and (iv) the First Closing Base Purchase Price or Second Closing Base Purchase Price, as applicable, shall be adjusted downward by the Allocated Value (or portion thereof) of the Acquired Asset affected by such Material Required Consent.  Promptly after any such Material Required Consent is obtained after such applicable Closing, (A) Seller shall assign, transfer, and convey to Purchaser, and Purchaser shall assume from Seller, the applicable Acquired Asset or Assumed Liabilities covered by the Material Required Consent pursuant to special-purpose assignment and assumption documents substantially consistent with the Transaction Documents, and (B) Purchaser shall pay to Seller the Allocated Value (or portion thereof) of the applicable Acquired Asset affected by such Material Required Consent that was subtracted from the First Closing Base Purchase Price or Second Closing Base Purchase Price, as applicable, with respect to such Material Required Consent in accordance with Section 10.9(c).  Notwithstanding anything in this Agreement to the contrary, if a Material Required Consent has not been obtained prior to the Final Settlement Date or such Material Required Consent prohibits the transfer of an affected Acquired Asset or Assumed Liability, such affected Acquired Asset or Assumed Liability shall not be transferred from Seller

42

to Purchaser under this Agreement or the other Transaction Documents and shall be deemed to be excluded from the Acquired Assets and Assumed Liabilities and retained by Seller as an “Excluded Asset”.

(a)                                 Compliance with Preferential Rights. Seller shall use its Commercially Reasonable Efforts (but in no event required to make any payments or incur any material obligations owed to any Person) to comply with any Preferential Rights by sending written notice of this Agreement, within ten (10) Business Days after the Execution Date, to all Persons holding any such Preferential Rights set forth on Section 8.2 of the Disclosure Schedule, offering to sell to each such Person that portion of the Acquired Assets for which such a Preferential Right is held for an amount equal to the Allocated Value of such portion of the Acquired Assets.

(b)                                 Notification. If, during the course of its Due Diligence Review, Purchaser discovers any Preferential Right that is not set forth on Section 8.2 of the Disclosure Schedule and which are applicable to the Acquired Assets, Purchaser shall promptly after discovery provide written notice to Seller of such Preferential Right, whereupon Seller shall promptly thereafter comply with such Preferential Right in accordance with Section 10.10(a).

(c)                                  Consummation Before any Closing. If, before the applicable Closing Date, any Preferential Right affecting any portion of the Acquired Assets is exercised and the sale to the holder of such Preferential Right is consummated, then that portion of the Acquired Assets affected by such Preferential Right shall be excluded from the Acquired Assets conveyed at such Closing, and the Closing Amount shall be adjusted downward by the Allocated Value of such portion of the Acquired Assets.

(d)                                 Consummation After Closing. If, with respect to a Preferential Right applicable to any portion of the Acquired Assets, the holder of such Preferential Right timely and properly exercises such Preferential Right before the applicable Closing Date but the purchase and sale of the affected Acquired Assets to the holder of such Preferential Right is not consummated before such Closing Date, then:  (i) the First Closing Base Purchase Price or Second Closing Base Purchase Price, as applicable, shall be reduced as a result of such Preferential Right by the Allocated Value of such Acquired Assets; (ii) the affected Acquired Asset shall be retained by Seller at such Closing; (iii) if the sale of the affected Acquired Assets to the holder of such Preferential Right occurs after such Closing but prior to the Final Settlement Date, Seller shall satisfy the obligations to such holder related to such Preferential Right, (iv) if the sale to the holder of the Preferential Right is not consummated before the Final Settlement Date (including, if the time frame for the exercise of the Preferential Right expires without exercise before the Final Settlement Date), then in connection with the final settlement under Section 14.1, the Seller shall convey such Acquired Asset to Purchaser effective as of the Effective Time pursuant to an assignment and conveyance substantially in the form of Exhibit D subject to such Preferential Right, if still outstanding as of the Final Settlement Date, and simultaneously with such conveyance Purchaser shall pay to Seller the Allocated Value of such portion of the Acquired Assets.

(e)                                  Open Preferential Rights.  If, with respect to a Preferential Right applicable to any portion of the Acquired Assets, the time frame for the exercise of such Preferential Right has not expired before the applicable Closing Date and Seller has not received from the holder of such Preferential Right either a notice of such holder’s intent not to exercise such Preferential Right or a waiver of such Preferential Right, then:  (i) the First Closing Base Purchase Price or Second Closing Base Purchase Price, as applicable, shall not be reduced as a result of such

43

Preferential Right; (ii) the affected Acquired Asset shall be conveyed by Seller to Purchaser at such Closing (to the extent applicable); and (iii) Purchaser shall comply with, be responsible for and perform all obligations arising with or attributable to such Preferential Right.

(f)                                   Certain Acknowledgements.  Purchaser acknowledges that Seller desires to sell all of the Acquired Assets to Purchaser and would not have entered into this Agreement but for Purchaser’s agreement to purchase all of the Acquired Assets as herein provided.  Accordingly, it is expressly understood and agreed that Seller does not desire to sell any Acquired Assets affected by a Preferential Right to Purchaser unless the sale of all of the Acquired Assets is consummated by the applicable Closing Date in accordance with the terms of this Agreement.  In furtherance of the foregoing, Seller’s obligation hereunder to sell the Acquired Assets affected by a Preferential Rights to Purchaser is expressly conditioned upon the consummation by the applicable Closing Date of the sale of all of the Acquired Assets (other than Excluded Assets or other Acquired Assets excluded from such Closing pursuant to the express provisions of this Agreement) in accordance with the terms of this Agreement, either by conveyance to Purchaser or conveyance pursuant to an applicable Preferential Right; provided that, nothing herein is intended or shall operate to extend or apply any Preferential Right to any portion of the Acquired Assets that is not otherwise burdened thereby.  Time is of the essence with respect to the Parties’ agreement to consummate the sale of the Acquired Assets by the Closing Date.

10.11                 Casualty Loss. If, after the Execution Date and before any applicable Closing, a Casualty Loss occurs with respect to a portion of the Acquired Assets, then, notwithstanding such Casualty Loss, Purchaser and Seller shall proceed with the purchase and sale of the affected Acquired Assets without reduction of the First Closing Base Purchase Price or Second Closing Base Purchase Price, as applicable,, and Seller shall:  (a) pay to Purchaser at the Closing all sums paid to Seller by Governmental Authorities and third parties before such Closing by reason of such Casualty Loss; and (b) assign, transfer, and convey to Purchaser all rights of Seller to any insurance proceeds received by Seller, as well as all of the right, title, and interest of Seller in and to any claims, causes of action, unpaid proceeds, or other payments from Governmental Authorities or third parties arising out of such Casualty Loss. Before any Closing, Seller shall not voluntarily compromise, settle, or adjust any amounts payable by reason of any Casualty Loss without first obtaining the written consent of Purchaser, which consent shall not be unreasonably withheld, delayed or conditioned.

10.12                 Change of Operator. Seller and Purchaser each agree to use their respective Commercially Reasonable Efforts to obtain all consents, authorizations, and approvals necessary to cause Purchaser to be elected as the operator of that portion of the Acquired Assets operated by Seller that are assigned to Purchaser as of the applicable Closing Date; provided, however, in no event shall Seller make any payments or incur any material obligations owed to any Person or liabilities in connection with obtaining any such consents, authorizations or approvals), and Purchaser hereby consents and agrees, subject to obtaining such necessary consents, authorizations, and approvals, to accept the designation, responsibilities, and Liabilities as the operator of such Acquired Assets.

(e)                                  If this Agreement is terminated by Purchaser under Section 12.1(a) because the First Closing has not occurred solely as a result of the failure or breach by Seller of any representations, warranties or covenants of Seller set forth in this Agreement that has prevented the satisfaction of the conditions of Purchaser set forth in Section 11.3, then, subject to Section 17.2 and the other provisions of this Agreement, Seller shall remain liable to Purchaser for all Losses incurred by Purchaser arising out of or relating to such breach or default and Purchaser shall have the right to obtain a decree or order of specific performance, mandamus, or other injunctive relief or equitable remedy to enforce the observance and performance of this Agreement against Seller. The Parties agree that if this Agreement is terminated as provided in this Section 12.2(e), irreparable damage to Purchaser would occur, no adequate remedy at Law would exist and damages would be difficult to determine, and the Purchaser shall be entitled to seek specific performance and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy.

The Parties agree that if this Agreement is terminated as provided in this Section 12.2(f), irreparable damage to Purchaser would occur, no adequate remedy at Law would exist and damages would be difficult to determine, and the Purchaser shall be entitled to seek specific

51

performance and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy. Notwithstanding the foregoing, in the event that Purchaser seeks damages at Law for any termination under this Section 12.2(f), the aggregate Liability of Seller for such damages under this Section 12.2 or otherwise under this Agreement or in connection with the Contemplated Transactions from and after the termination of this Agreement shall not exceed an amount equal to ten percent (10%) of the Second Closing Base Purchase Price and Purchaser hereby waives, relinquishes and releases Seller from any liability or Losses for such damages in excess of such amount.

(g)                                  Promptly, but in no event later than three (3) Business Days after the termination date of this Agreement, the Parties hereto shall execute and deliver to the Escrow Agent written instructions instructing the Escrow Agent to disburse via wire transfer of immediately available funds the entirety of the Deposit to the applicable Party entitled to receive the Deposit as provided in this Section 12.2.

(i)                                     all rights and obligations of the Parties under this Agreement with respect to or relating to the Second Closing Assets, the Second Closing and all covenants, representations or warranties of the Parties made hereunder or under any other Transaction Document with respect thereto shall terminate without any further Liability or obligation of any Party to any other Party; provided, however, that the provisions in Sections 10.13 and 10.14 (relating to confidentiality and press releases), the indemnification obligations of Purchaser under Section 4.3(b), the provisions of Section 12.2 and this Section 12.3 (relating to termination), the provisions in Article 1 and Article 17, the other provisions of this Agreement that expressly survive the termination of this Agreement, and the definitions in Appendix A (to the extent used in the foregoing Sections, Articles, and provisions) shall each survive the termination of this Agreement and remain in full force and effect; and

14.7                        Further Assurances. From time to time after each Closing, Seller shall execute, acknowledge, and deliver, or cause to be executed, acknowledged, and delivered, to Purchaser, and Purchaser shall execute, acknowledge, and deliver, and cause to be executed, acknowledged, and delivered to Seller, such further documents and instruments, and take such other and further actions, as may be reasonably requested by each such Party in order to more effectively assure to Purchaser the full beneficial use and enjoyment of the applicable Acquired Assets purchased by Purchaser, and to more effectively assure to Seller the full assumption by Purchaser of, and release of Seller from, any Liability with respect to the Assumed Liabilities, and to otherwise more fully accomplish the Contemplated Transactions, in each case subject to the terms and conditions in this Agreement.

14.8                        Post-Closing Documents.  All required documentary, filing, transfer fees and recording fees and expenses in connection with the filing and recording of the assignments (including the Assignment), conveyances or other instruments required to convey title to any applicable Acquired Assets to Purchaser shall be borne solely by Purchaser.  Promptly after each applicable Closing, Purchaser shall (a) record all assignments of all Acquired Assets executed at the applicable Closing in the records of the applicable Governmental Authority, (b) if applicable, send notices to vendors supplying goods and services for all such Acquired Assets and to the operator of such Assets of the assignment of such Assets to Purchaser, (c) actively pursue the unconditional approval of all un-obtained consents and approval of

Article 15
Tax Matters

15.1                        Apportionment of Property Taxes.

(a)                                 Oil and Gas Property Taxes. The Parties acknowledge that, with respect to the Acquired Assets that qualify as oil or gas leases or lands with the meaning of Colorado Revised Statutes Section 39-7-101, Colorado Property Taxes are measured with respect to Hydrocarbon production revenue from the leases or lands during a calendar year, levied on January 1 of the subsequent calendar year, and payable in the following year (“Oil and Gas Property Taxes”). Seller alone shall be liable for Oil and Gas Property Taxes attributable to 2015 Hydrocarbon production revenue from the First Closing Assets, which Taxes were levied in 2016 and will be payable in 2017, and the full amount of these Oil and Gas Taxes attributable to 2015 Hydrocarbon production revenue shall be reflected as a downward adjustment to the Base Purchase Price pursuant to Section 3.2(a)(ii)(C).  Oil and Gas Property Taxes attributable to 2016 Hydrocarbon production revenue from the First Closing Assets, which will be levied in 2017 and payable in 2018, shall be apportioned between the Parties in proportion to the time period that each respective Party owned each First Closing Asset during the 2016 taxable year, such that Seller shall be liable for these Oil and Gas Property Taxes in proportion to the 2016 Hydrocarbon production revenue from each First Closing Asset prior to the Effective Time applicable to that First Closing Asset, and Purchaser shall be liable for these Oil and Gas Property Taxes in proportion to the 2016 Hydrocarbon production revenue arising from each First Closing Asset on and after the Effective Time applicable to that First Closing Asset.  The amount of the Seller’s liability for Oil and Gas Taxes attributable to 2016 Hydrocarbon production revenue shall be reflected as a downward adjustment to the Base Purchase Price pursuant to Section 3.2(a)(ii)(C).  Buyer alone shall be liable for Oil and Gas Property Taxes attributable to 2017 Hydrocarbon production revenue from the First Closing Assets. For the purpose of determining an adjustment to the Purchase Price pursuant to Section 3.2 and/or Section 14.1, Oil and Gas Property Taxes for the 2017 tax year (i.e., those based on the value of 2016 production, levied for the 2017 tax year, and payable in 2018) shall be estimated based on the most recently certified mill levy applicable to a First Closing Asset subject to Oil and Gas Property Taxes and the value of the production attributable to a First Closing Asset subject to Oil and Gas Property Taxes occurring prior to the Effective Time (annualized by multiplying such value by four).  For purposes of this Agreement, the resulting Purchase Price adjustment under Section 3.2 and/or Section 14.1 for the First Closing Assets will be the full and final settlement of Seller’s responsibility for all such Oil and Gas Property Taxes without regard to the actual Tax rates or assessments (the “Settled Oil and Gas Property Taxes”).  For the avoidance of doubt, the principles of this Section 15.1(a) shall be applied to the Second Closing Assets, provided that if the Second Closing takes place in 2017, the Oil and Gas Property Taxes attributable to 2016 Hydrocarbon production revenue from Second Closing Assets shall be treated in the manner provided above for 2015 Hydrocarbon production revenue, and the Oil and Gas Property Taxes attributable to 2017 Hydrocarbon production revenue from Second Closing Assets shall be treated in the manner provided above for 2016 Hydrocarbon production revenue, and if the Second Closing takes place in 2018, the Oil and Gas

61

Property Taxes attributable to 2017 Hydrocarbon production revenue from Second Closing Assets shall be treated in the manner provided above for 2015 Hydrocarbon production revenue, and the Oil and Gas Property Taxes attributable to 2018 Hydrocarbon production revenue from Second Closing Assets shall be treated in the manner provided above for 2016 Hydrocarbon production revenue.

(b)                                 Other Property Taxes. Property Taxes on Acquired Assets other than those described in Section 15.1(a) (“Other Property Taxes”) shall be deemed attributable to the period of ownership by each Party of each applicable Acquired Asset subject to Other Property Taxes, and liability for such Other Property Taxes shall be allocated to Seller for all periods (and portions thereof) ending prior to the Effective Time applicable to each Acquired Asset and to Purchaser for all periods (and portions thereof) beginning at or after the Effective Time applicable to each Acquired Asset.  To the extent the actual amount of an Other Property Taxes that are attributable to a period ending prior to the Effective Time (but not due and payable prior to the First Closing or Second Closing, as applicable) is not determinable at the time an adjustment to the Purchase Price is to be made with respect to such Other Property Taxes pursuant to Section 3.2 and/or Section 14.1, as applicable, the Parties shall utilize the most recent information available in estimating the amount of such Other Property Taxes for purposes of such adjustment, and the amount of such Other Property Taxes used for purposes of Section 3.2 and/or Section 14.1 shall be considered full and final settlement of Seller’s responsibility for all such Other Property Taxes without regard to the actual Tax rates or assessments (the “Settled Other Property Taxes,” and together with the Settled Oil and Gas Property Taxes, the “Settled Property Taxes”).

15.2                        Apportionment of Severance Taxes. Severance Taxes shall be deemed attributable to the period during which production occurred on Acquired Assets of the Hydrocarbons subject to such Severance Taxes, and liability therefor shall be allocated to Seller for Hydrocarbon production from each Acquired Asset prior to the Effective Time applicable to that Acquired Asset, and to Purchaser for Hydrocarbon production from each Acquired Asset on and after the Effective Time applicable to that Acquired Asset.  For the purpose of calculating adjustments to the Purchase Price under Section 3.2 and/or Section 14.1, Severance Taxes for which the actual liability amount is not known as of such time shall be estimated based on current Colorado Severance Tax rates with the resulting Purchase Price adjustment under Section 3.2 and/or Section 14.1 to be considered full and final settlement of all such Taxes without regard to the actual Tax rates or assessments (the “Settled Severance Taxes,” and together with the Settled Property Taxes, the “Settled Asset Taxes”) for purposes of this Agreement.

15.3                        Tax Returns. Subject to Purchaser’s indemnification rights under Article XVI of this Agreement, after Closing, Purchaser shall timely file or cause to be filed all Tax Returns for Asset Taxes required to be filed after the Closing and shall timely pay or cause to be paid to the taxing authorities all Asset Taxes that become due and payable after the Closing.  Any penalty, addition to Tax, or interest levied or assessed with respect to any Asset Tax shall be allocated to, and shall be payable by, the Party to which the Tax to which such penalty, addition to Tax or interest relates is allocated, regardless of when such penalty, addition to Tax, or interest is levied or assessed; provided, however, that the liability for any penalty, addition to Tax, or interest levied or assessed with respect to any failure of Purchaser to comply with the previous sentence shall be allocated to, and shall be payable by, Purchaser; provided further, however, that Purchaser shall not be liable for any penalty, addition to Tax, or interest levied or assessed with respect to any Tax Return that was required to be filed on or before the Closing Date.

15.4                        Transfer Taxes. The Purchase Price excludes, and Purchaser shall be liable for the entire amount of any sales, use, excise, stock, stamp, documentary, filing, recording, registration, authorization, and similar Taxes, fees, transfer fees, and charges incurred or required to be paid by any of the

62

Indemnified Parties in connection with the Contemplated Transactions.  If required by applicable law, Seller will charge and collect any applicable sales tax unless Purchaser provides a valid exemption or direct pay certificate.

15.5                        Income Taxes.  Notwithstanding anything to the contrary in this Agreement, each Party shall retain responsibility for, and shall bear and pay, all Income Taxes incurred by or imposed on it, its direct or indirect owners or Affiliates, or any combined, unitary, or consolidated group of which any of the foregoing is or was a member, and no such Taxes shall be taken into account as adjustments to the Purchase Price under Section 3.2 and/or Section 14.1, as applicable.

15.6                        Form 8594. Seller and Purchaser shall cooperate in the preparation of Internal Revenue Service Form 8594, pursuant to Temporary Treasury Regulation section 1.1060-1T, to report the allocation of the Purchase Price among the applicable Acquired Assets. To the extent required by Code section 1060 and any Treasury Regulations promulgated thereunder, any such allocations shall be consistent with the Purchase Price allocation as set forth in Exhibit C.  Except as required by Law, none of the Parties (or their applicable Affiliates) shall take any position on its Tax returns that is inconsistent with the allocation of the Purchase Price set forth on Exhibit C (plus other capitalized costs) as so agreed or as adjusted.

15.7                        Section 1031 Exchange Accommodation.

(a)                                 Notwithstanding anything herein to the contrary, but subject to this Section 15.7, either Party (in such capacity, the “Exchanging Party”) may at any time prior to any Closing assign all or any portion of its rights under this Agreement and take such other steps as required to satisfy the requirements of one or more like-kind exchange pursuant to Code section 1031 with respect to such Exchanging Party (an “Exchange Transaction”). Subject to the other provisions of this Section 15.7, the other Party (in such capacity, the “Non-Exchanging Party”) shall, as and when reasonably requested by the Exchanging Party from time to time, execute and deliver, or cause to be executed and delivered, all such documents and instruments, and take, or cause to be taken, all such further actions as the Exchanging Party may determine is reasonably necessary or appropriate for purposes of causing the Contemplated Transactions, in whole or in part, to satisfy the requirements of Code section 1031 with respect to the Exchanging Party.

(b)                                 Notwithstanding the foregoing, unless the Exchanging Party provides for reimbursement or indemnity reasonably acceptable to the Non-Exchanging Party: (i) the Non-Exchanging Party shall not be obligated to pay any additional costs or incur any additional obligations or Liabilities in connection with the Contemplated Transactions if such costs, obligations or Liabilities arise out of or result from the Exchange Transaction (ii) the Non-Exchanging Party shall not be obligated to take title to any other assets or property, or to undertake any obligations to any third party, as a result of the Exchange Transaction; and (iii) nothing herein shall be deemed the agreement of the Non-Exchanging Party to delay any Closing of, or payment under, this Agreement, in connection with the Exchange Transaction. The Non-Exchanging Party shall provide no assurance to the Exchanging Party that any particular tax treatment will be given to the Exchanging Party as a result of the Exchange Transaction, and the Non-Exchanging Party shall have no obligation to the Exchanging Party or any other Person if the Exchange Transaction fails to qualify as a “like kind exchange” under Code section 1031 or similar state or local tax provision.

(c)                                  The Parties acknowledge and agree that a whole or partial assignment by the Exchanging Party of rights under this Agreement or any of the Acquired Assets to a qualified intermediary or exchange accommodation titleholder as required by Code section 1031 and the administrative rules governing same (an “Intermediary”) shall not (i) release the Exchanging

63

Party from any of its Liabilities and obligations under this Agreement or any other Transaction Document, or (ii) expand any Liabilities or obligations of the Non-Exchanging Party under this Agreement or any other Transaction Document. The Exchanging Party and any such Intermediary, and their successors and assigns, shall be jointly and severally liable for the obligations and Liabilities of the Exchanging Party under this Agreement and the other Transaction Documents, and shall indemnify, defend and hold harmless the Non-Exchanging Party from and against all Claims, Losses and Liabilities, if any, arising out of or resulting from an Exchange Transaction without regard to the Indemnification Threshold, including any Claims, Losses and Liabilities (but only to the extent such Claims, Losses and Liabilities would not have arisen if the Contemplated Transactions had been conducted without the Exchange Transaction) arising out of or resulting from the transfer, assignment or conveyance of any Acquired Assets to an Intermediary instead of the Exchanging Party.

(d)                                 In order to minimize administrative burdens as well as third party preferential purchase and consent rights, Seller and Purchaser may transfer the Acquired Assets to a newly-formed, Delaware limited liability company wholly owned by Seller (a “Title LLC”), and then may substitute the assignment of such Acquired Assets by the assignment of all of the membership interests in such Title LLC directly or through an Intermediary. Subject to this Section 15.7, particularly Section 15.7(b) and Section 15.7(c), the Seller and Purchaser agree to work in good faith to accommodate utilization of a Title LLC in an Exchange Transaction if desired by either party.  Any assignment by an Exchanging Party to an Intermediary made in violation of this Section 15.7 shall be void.

15.8                        Post-Closing Tax Matters.  After Closing, each of Purchaser and Seller shall:

(a)                                 reasonably cooperate and assist the other (i) in preparing any Tax Returns relating to any Tax relating to the Acquired Assets, or the Transaction, and (ii) in qualifying for any exemption or reduction in Tax that may be available;

(b)                                 reasonably cooperate in preparing for any audits, examinations or other Tax proceedings by, or disputes with, taxing authorities regarding any Tax relating to the Acquired Assets or the Transaction;

(c)                                  make available to the other, and to any taxing authority as reasonably requested, any information, records, and documents relating to a Tax incurred or imposed in connection with the Acquired Assets or the Transaction;

(d)                                 provide notice within 10 days of receipt to the other in writing of any pending or threatened Tax audit, examination, or assessment received in writing that could reasonably be expected to affect the other’s Tax liability under applicable Law or this Agreement (a “Tax Controversy”), and to promptly furnish the other with copies of all correspondence with respect to any Tax Controversy; and

(e)                                  allow the other to participate, at its own expense, in any Tax Controversy, and not settle any Tax Controversy without the prior written consent of the other, which may not be unreasonably withheld, conditioned, or delayed.

If a Party in good faith believes that an Indemnified Seller Party or an Indemnified Purchaser Party (an “Indemnified Party”) is or may be entitled to indemnification or a defense under Section 16.2, and such Party desires to assert its right to indemnification or a defense, such Party must deliver a written notice (a “Claim Notice”) to the Party that the Indemnified Party believes is obligated to provide such indemnification or defense to the Indemnified Party (the “Indemnifying Party”).

16.4                        Third-Party Claims. With respect to a Third-Party Claim:

(a)                                 Defense by Indemnifying Party. If an Indemnified Party asserts it is entitled to indemnification or a defense in connection with a Third-Party Claim, at the election of the

67

Indemnifying Party made by written notice to the Indemnified Party within thirty (30) Business Days after receipt of a Claim Notice with respect to such Third-Party Claim, the Indemnified Party shall permit the Indemnifying Party to assume control of the defense of such Third-Party Claim, including the determination of all appropriate actions, the negotiation of settlements on behalf of the Indemnified Party, and the conduct of any related Proceedings through attorneys of the Indemnifying Party’s choice; provided, however, the Indemnified Party is authorized, prior to and during such thirty (30) Business 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. If an Indemnifying Party elects to assume control of such defense:

(i)                                     The Indemnifying Party shall be deemed to have admitted its obligation to indemnify and defend the Indemnified Party in respect of such Third-Party Claim and may not later contest such obligation; provided, however, such admission shall in no event be deemed to waive any limitations as to the liability of, or expand any obligations of such Indemnifying Party;

(iii)                               the Indemnified Party shall make available to the Indemnifying Party all documents and materials in the possession or control of the Indemnified Party relating to the Third-Party Claim and provide such other information and assistance that the Indemnifying Party shall reasonably deem necessary to the proper defense of the Third-Party Claim;

(iv)                              the Indemnified Party shall make available to the Indemnifying Party all privileged documents and materials in the possession or control of the Indemnified Party relating to the Third-Party Claim pursuant to the terms of a joint defense agreement or common interest agreement mutually agreed in good faith by the Indemnified Party and the Indemnifying Party, unless counsel for the Indemnified Party reasonably determines that providing such information and entering into such joint defense agreement or common interest agreement would compromise conflicting Claims of the Indemnified Party and the Indemnifying Party;

(v)                                 the Indemnifying Party shall keep the Indemnified Party informed of all material developments and events relating to the defense of the Third-Party Claim, and provide copies of any materials disclosed to the claimant or plaintiff in connection with the defense of the Third-Party Claim; and

(vi)                              the Indemnifying Party shall have the right to settle, adjust, or compromise such Third-Party Claim: (A) with the written consent of the Indemnified Party, such consent not to be unreasonably withheld, delayed or conditioned; or (B) without the consent of the Indemnified Party, provided that such settlement, adjustment, or compromise includes an unconditional release of the Indemnified Party and the other Indemnified Seller Parties or Indemnified Purchaser Parties, as applicable; imposes no relief other than monetary damages; and there is no finding of violation of Law or violation of the rights of any Person.

(b)                                 Defense By Indemnified Party. If an Indemnified Party asserts it is entitled to a defense of the Third-Party Claim under Section 16.2, and the Indemnifying Party does not timely elect to assume control of the defense, then:

68

(i)                                     if it is finally determined in a non-appealable final judgment of a court of competent jurisdiction that the Indemnifying Party was obligated to provide such defense, all costs and expenses incurred by the Indemnified Party to defend the Third-Party Claim shall be for the account of the Indemnifying Party;

(ii)                                  whether or not the Indemnifying Party is obligated to provide such defense, the Indemnifying Party shall make available to the Indemnified Party all non-privileged documents and materials in the possession or control of the Indemnifying Party relating to the Third-Party Claim and provide such other information and assistance that the Indemnified Party shall reasonably deem necessary to the proper defense of the Third-Party Claim;

(iii)                               the Indemnified Party shall keep the Indemnifying Party informed of all material developments and events relating to the defense of the Third-Party Claim, and provide copies of any materials disclosed to the claimant or plaintiff in connection with the defense of the Third-Party Claim; and

(iv)                              the Indemnified Party shall have the right to settle, adjust, or compromise such Third-Party Claim with the written consent of the Indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned.

(c)                                  Cooperation.

(c)                                  without limiting the foregoing, Seller shall have no Liability under Section 16.2(a)(i) or (ii) for indemnification until and unless the aggregate amount of the Liability for all Losses which exceed the Indemnification Threshold exceeds one and one-half percent (1.5%) of the Base Purchase Price, and then only to the extent such aggregate amount exceeds one and one-half percent (1.5%) of the Base Purchase Price;

(d)                                 the Parties shall treat, for Tax purposes, any amounts paid under this Article 16 as an adjustment to the Purchase Price;

69

(e)                                  each Indemnified Party shall make reasonable efforts to mitigate or minimize all Losses upon and after becoming aware of any event or condition which would reasonably be expected to give rise to any Losses and Claims that are indemnifiable hereunder and if an Indemnified Party fails to so mitigate any indemnifiable Losses and Claims under the preceding sentence, the Party that would otherwise have an indemnity obligation hereunder with respect to such Losses and Claims shall have no liability for any portion of such Losses and Claims that reasonably could have been avoided or mitigated had the Indemnified Party made such efforts;

(b)                                 Waiver. If the First Closing occurs, except for the right of Purchaser to indemnification under Section 16.2, Purchaser shall be deemed to have waived, to the fullest extent permitted under Law, any right to contribution against any Indemnified Seller Party (including any contribution under CERCLA or any other Environmental Law) and any and all other Claims and rights it may have against or from any Indemnified Seller Party arising under or based on any Law or other legal theory (whether in contract, tort, equity, or otherwise).

16.8                        Releases. Except for the remedies expressly contained in Section 16.2(a) for which Seller has agreed to indemnify the Indemnified Purchaser Parties under this Agreement or Seller’s special warranty of title set forth in the Assignment, at each applicable Closing Purchaser, on its own behalf and on behalf of the other Indemnified Purchaser Parties, shall be deemed to have waived and released the Indemnified Seller Parties from, and Purchaser shall assume, any and all Claims and Losses the Purchaser or the Indemnified Purchaser Parties might now or subsequently may have, based on, relating to or arising out of this Agreement or Seller’s ownership, use or operation of the applicable Acquired Assets that are the subject of such Closing, or the condition, quality, status or nature of the Acquired Assets that are the subject of such Closing, including rights to contribution under any Environmental Laws, breaches of statutory and implied warranties, nuisance or other tort actions, rights to punitive damages, common law rights of contribution, any rights under insurance policies issued or underwritten by the other Party or any Affiliate of such Party and any rights under agreements between Seller and any Indemnified Seller Party, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY RELEASED PERSON, INVITEES OR THIRD PARTIES, but excluding, however, any remaining balance owed by Seller to any other Affiliate of Seller at the end of the applicable Closing Date for provision of goods or services, or employment related costs, or other ordinary course of business expenses, with respect to the ownership or operation of the Assets that are the subject of such Closing.

16.9                        Subrogation. To the extent of the indemnification obligations in this Agreement, Purchaser and Seller hereby waive for themselves and their respective successors and assigns, including any insurers, any rights to subrogation for Losses for which such Party is liable or against which such Party indemnifies any other Person under this Agreement. If required by applicable insurance policies, each Party shall obtain a waiver of such subrogation from its insurers.

71

16.10                 Reservation as to Non-Parties. Nothing in this Agreement is intended to limit or otherwise waive any recourse Seller or Purchaser may have against any Person that is not a party to this Agreement for any obligations or Liabilities that may be incurred with respect to the Acquired Assets or the Assumed Liabilities.

16.11                 Express Negligence/Conspicuous Manner. WITH RESPECT TO THIS AGREEMENT, BOTH PARTIES AGREE THAT THE PROVISIONS SET OUT IN THIS ARTICLE 16 COMPLY WITH THE REQUIREMENT, KNOWN AS THE EXPRESS NEGLIGENCE RULE, TO EXPRESSLY STATE IN A CONSPICUOUS MANNER TO AFFORD FAIR AND ADEQUATE NOTICE THAT THIS AGREEMENT HAS PROVISIONS REQUIRING THE INDEMNIFYING PARTY TO BE RESPONSIBLE FOR THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE OR CONCURRENT), STRICT LIABILITY, OR OTHER FAULT OF THE INDEMNIFIED PARTY.  EACH OF SELLER AND PURCHASER UNDERSTAND THAT PURSUANT TO THIS AGREEMENT, EACH PARTY IS SOMETIMES AN INDEMNIFYING PARTY AND SOMETIMES AN INDEMNIFIED PARTY.  EACH INDEMNIFYING PARTY REPRESENTS TO THE INDEMNIFIED PARTY (1) THAT IT, THE INDEMNIFYING PARTY HAS CONSULTED AN ATTORNEY CONCERNING THIS AGREEMENT OR, IF IT HAS NOT CONSULTED AN ATTORNEY, THAT IT WAS PROVIDED THE OPPORTUNITY AND HAD THE ABILITY TO SO CONSULT, BUT MADE AN INFORMED DECISION NOT TO DO SO, AND (2) THAT IT, THE INDEMNIFYING PARTY FULLY UNDERSTANDS ITS OBLIGATIONS UNDER THIS AGREEMENT.
