PURCHASE AND SALE

2.1 Purchase and Sale.

(a) Subject to the terms and conditions of this Agreement, Buyer agrees to purchase from SM Energy, and SM Energy agrees to sell, assign and deliver to Buyer the Assets for the consideration specified in this Article II.

(b) SM Energy shall reserve and retain all of the Excluded Assets.

2.2 Purchase Price.

Subject to the other terms and conditions of this Agreement, the purchase price for the Assets shall be Seven Hundred Eighty-Five Million Dollars ($785,000,000) (the “Purchase Price”). The Purchase Price shall be payable as follows:

(a) Upon the earlier of October 21, 2016, or one (1) Business Day following the day when the Escrow Agent opens the escrow account, Buyer shall deposit by wire transfer in immediately available funds with Wells Fargo Bank, National Association (the “Escrow Agent”), the sum of $78,500,000 (such amount, together with any interest earned thereon (the “Deposit”), which Deposit shall be held in escrow by the Escrow Agent pursuant to the terms of the Escrow Agreement, and disbursed in accordance with the terms of this Agreement; and

(b) At Closing, Buyer shall pay SM Energy the Closing Amount by wire transfer in immediately available funds.

2.3 Deposit.

(a) If the transactions contemplated by Section 2.1 are not consummated on or before the Closing Date because of: the failure of Buyer to materially perform any of its obligations hereunder; provided, that SM Energy is not in material breach of the terms of this Agreement and is ready, willing and able to perform all of its obligations hereunder, or the failure of any of Buyer’s representations or warranties hereunder to be true and correct in all material respects (without regard to materiality qualifiers) as of the Execution Date and as of the Closing, then, in such event, SM Energy shall have the right to terminate this Agreement and receive the Deposit free of any claims by Buyer thereto, as provided in Section 12.2(b).

(b) If this Agreement is terminated by the mutual written agreement of the Parties, or if the Closing does not occur on or before the Closing Date for any reason other than as set forth in Section 2.3(a), then Buyer shall be entitled to the delivery of the Deposit, free of any claims by SM Energy with respect thereto.

(c) In the event of any termination of this Agreement as contemplated by Section 2.3(a) or Section 2.3(b) above, the Parties shall, in each case, immediately have the rights and obligations set forth in Section 12.2 and Section 12.3.

2.4 Adjustments to Purchase Price.

(a) For purposes of determining the amounts of the adjustments to the Purchase Price provided for in this Section 2.4, the principles set forth in this Section 2.4(a) shall apply. Buyer shall be entitled to all production of Hydrocarbons from or attributable to the Units, Leases, and Wells at and after the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets at or after the Effective Time, and shall be responsible for (and entitled to any refunds with respect to) all Operating Expenses incurred at and after the Effective Time. SM Energy shall be entitled to all Hydrocarbon production from or attributable to Units, Leases and Wells prior to the Effective Time (and all products and proceeds attributable thereto), and to all other income, proceeds, receipts and credits earned with respect to the Assets prior to the Effective Time, and shall be responsible for (and entitled to any refunds with respect to) all Operating Expenses incurred prior to the Effective Time. The Parties shall disclose to each other any revenues received after the date of final settlement of the Purchase Price pursuant to Section 2.6 to which the other Party is entitled and account to such Party within ten (10) days of receipt of such revenues. “Earned” and “incurred”, as used in the Agreement shall be interpreted in accordance with GAAP and Council of Petroleum Accountants Society standards, except as otherwise specified herein. For purposes of allocating production (and proceeds and accounts receivable with respect thereto), under this Section 2.4, (i) liquid Hydrocarbons shall be deemed to be “from or attributable to” the Units, Leases and Wells when they pass through the pipeline connecting into the storage facilities into which they are run and (ii) gaseous Hydrocarbons shall be deemed to be “from or attributable to” the Units, Leases and Wells when they pass through the royalty measurement meters, delivery point sales meters or custody transfer meters on the gathering lines or pipelines through which they are transported (whichever meter is closest to the well). SM Energy shall utilize reasonable interpolative procedures, consistent with industry practice, to arrive at an allocation of production when exact meter readings or gauging and strapping data are not available. As part of the Preliminary Settlement Statement, Buyer shall provide to SM Energy such data as is reasonably necessary to support any estimated allocation, for purposes of establishing the Closing Amount.

(b) The Purchase Price shall be adjusted upward by the following amounts (without duplication):

(i) an amount equal to the value of all marketable Hydrocarbons produced from or attributable to the Assets in storage or existing in stock tanks (excluding tank bottoms), pipelines and/or plants (including inventory) as of the Effective Time, the value to be based upon the contract price in effect as of the Effective Time (or if there is no contract price, then the market price in effect as of the Effective Time in the field in which such Hydrocarbons were produced) or if actually sold prior to the date of determination, the proceeds actually recovered by SM Energy attributable to such sale, net of amounts payable as royalties, overriding royalties and other burdens upon, measured by or payable out of such production and Asset Taxes;

(ii) an amount equal to all Operating Expenses for which Buyer is responsible under Section 2.4(a) paid by SM Energy that are attributable to the Assets from and after the Effective Time, whether paid before or after the Effective Time;

(iii) [reserved];

(iv) Subject Transfer Taxes paid by SM Energy with respect to the transactions contemplated by this Agreement;

(v) all Asset Taxes allocated to Buyer that are paid or to be paid by SM Energy; and

(vi) any other amount provided for elsewhere in this Agreement or otherwise agreed upon by the Parties.

(i) an amount equal to all proceeds actually received by or credited to SM Energy attributable to the sale of Hydrocarbons produced from or attributable to the Assets from and after the Effective Time or contained in storage or existing in stock tanks, pipelines and/or plants (including inventory) as of the Effective Time for which an upward Purchase Price adjustment was made pursuant to Section 2.4(b);

(ii) if SM Energy makes the election under Section 6.2(c)(i) with respect to a Title Defect, the Title Defect Amount with respect to such Title Defect if the Title Defect Amount has been determined prior to Closing;

(iii) if SM Energy makes the election under Section 7.1(b)(i) with respect to an Environmental Defect, the Remediation Amount with respect to such Environmental Defect if the Remediation Amount has been determined prior to Closing;

(iv) an amount determined pursuant to Section 7.1(b)(iii), Section 6.4(c)(ii) or Section 6.4(d)(i), as applicable, for any Asset excluded from the transaction contemplated hereby pursuant to such Sections;

(v) the value of any Casualty Loss pursuant to Section 6.3(b)(B);

(vi) all costs and expenses incurred by Buyer related to the Venting Obligations (which in no event will exceed $600,000);

(vii) an amount equal to all Operating Expenses for which SM Energy is responsible under Section 2.4(a) paid or payable by Buyer that are attributable to the Assets prior to the Effective Time;

(viii) any other amount provided for elsewhere in this Agreement or otherwise agreed upon by the Parties; and

(ix) all Asset Taxes allocated to Seller that are paid or to be paid by Buyer.

(d) If, prior to Closing, Buyer or SM Energy discovers an error in the Imbalances set forth in Schedule 3.10, then the Purchase Price shall be further adjusted at Closing (based on a value of (x) $1.00 per Mcf for gas multiplied by the total volume of such imbalances and (y) NYMEX (as of the Closing Date) less $6.00 per barrel multiplied by the total volume of oil imbalances) pursuant to Section 2.4(b)(iii) or Section 2.4(c)(vi), as applicable, and Schedule 3.10 will be deemed amended immediately prior to the Closing to reflect the Imbalances for which the Purchase Price is so adjusted.

2.5 Allocated Value.

(a)

(a) SM Energy and Buyer have agreed upon an allocation of the unadjusted Purchase Price among each of the Wells and Well Locations, and such allocations are set forth on Schedule 2.5(a) (the “Allocated Values”). SM Energy and Buyer agree that the Allocated Values shall be used in calculating adjustments to the Purchase Price as provided herein. Any adjustments to the Purchase Price, other than the adjustments provided for in Section 2.4, shall be applied on a pro rata basis to the amounts set forth in Schedule 2.5(a), as applicable, for all Assets. After all such adjustments are made, any adjustments to the Purchase Price made pursuant to Section 2.4 shall be applied to the amounts set forth on Schedule 2.5(a), as applicable, for the particular affected Assets.

(b) On or before the Closing Date, Buyer and SM Energy will agree upon an allocation of the unadjusted Purchase Price among each of the Assets, in compliance with the principles of Section 1060 of the Code, and the United States Treasury Regulations thereunder. Such allocation shall be in the format of Schedule 2.5(b). SM Energy and Buyer agree (i) that the Allocated Values, as adjusted pursuant to this paragraph, shall be used by SM Energy and Buyer as the basis for reporting asset values and other items for purposes of all federal, state, and local Tax Returns, including Internal Revenue Service Form 8594 and (ii) that neither they nor their Affiliates will take positions inconsistent with Schedule 2.5(b) (as adjusted pursuant to this paragraph) in notices to Governmental Bodies, in audit or other Proceedings with respect to Taxes, in notices to preferential purchase right holders, or in other documents or notices relating to the transactions contemplated by this Agreement without the consent of the other Party. Buyer and SM Energy further agree that, on or immediately after the Closing Date, they will mutually agree as to the further allocation of the values on Schedule 2.5(a) as to the relative portion of those values attributable to leasehold costs and depreciable equipment.

2.6 Settlement; Disputes.

(a) Not less than five (5) Business Days prior to the Closing, SM Energy shall prepare and submit to Buyer for review a draft settlement statement using the best information available to SM Energy (the “Preliminary Settlement Statement”) that shall set forth the adjusted Purchase Price reflecting each adjustment made in good faith in accordance with this Agreement as of the date of preparation of such Preliminary Settlement Statement. Within three (3) Business Days of receipt of the Preliminary Settlement Statement, Buyer has the right, but not the obligation, to deliver to SM Energy a written report containing all changes with the explanation therefor that Buyer proposes to be made to the Preliminary Settlement Statement.

The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Purchase Price at Closing (such adjusted price, the “Preliminary Purchase Price”). If the Parties cannot agree on the Preliminary Settlement Statement prior to the Closing, the Preliminary Settlement Statement as presented by SM Energy and prepared in accordance with this Section 2.6(a) will be used to adjust the Purchase Price at Closing.

(b) On or before 120 days after the Closing, a final settlement statement (the “Final Settlement Statement”) will be prepared by SM Energy, based on actual income and expenses attributable to the periods prior to and after the Effective Time, including any amount set forth in the Preliminary Settlement Statement as well as any settlement during the term of the Transition Services Agreement, and which takes into account all final adjustments made to the Purchase Price and shows the resulting final adjusted Purchase Price (the “Final Purchase Price”). SM Energy shall, at Buyer’s request, supply reasonable documentation in its or its Affiliates’ possession available to support the actual revenue, expenses and other items for which adjustments are made. The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement. As soon as practicable, and in any event within 45 days, after receipt of the Final Settlement Statement, Buyer has the right, but not the obligation, to return a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the “Dispute Notice”). If the Final Purchase Price set forth in the Final Settlement Statement is mutually agreed upon by SM Energy and Buyer, the Final Settlement Statement and the Final Purchase Price shall be final and binding on the Parties. Once the Final Purchase Price has been agreed upon by the Parties pursuant to this Section 2.6(b) or determined by the Accounting Arbitrator pursuant to Section 2.6(c), as applicable, the Parties shall execute a certificate setting forth such agreed or determined, as applicable, Final Purchase Price, which shall be binding on the Parties for all purposes of this Agreement.

(c) If the Parties are unable to resolve the matters addressed in the Dispute Notice, each of Buyer and SM Energy shall, within 14 Business Days following the delivery of such Dispute Notice, summarize its position with regard to such dispute in a written document and submit such summaries to the Houston, Texas office of KPMG LLP or such other Person as the Parties may mutually select (the “Accounting Arbitrator”), together with the Dispute Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall render a decision choosing either SM Energy’s position or Buyer’s position with respect to each matter addressed in any Dispute Notice, based on the materials described above. Any decision rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on the Parties and will be enforceable against any of the Parties in any court of competent jurisdiction. The costs of such Accounting Arbitrator shall be borne one-half by Buyer and one-half by SM Energy.

2.7 Section 1031 Like-Kind Exchange.

SM Energy and Buyer hereby agree that SM Energy shall have the right at any time prior to completion of all the transactions that are to occur at Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary (as that term is defined in Section 1.1031(k)-1(g)(4)(v) of the Treasury Regulations) in order to accomplish the transaction

in a manner that will comply, either in whole or in part, with the requirements of a like-kind exchange pursuant to Section 1031 of the Code. Likewise, Buyer shall have the right at any time prior to completion of all the transactions that are to occur at Closing to assign all or a portion of its rights under this Agreement to a Qualified Intermediary for the same purpose. If SM Energy assigns all or any of its rights under this Agreement for this purpose, Buyer agrees to (a) consent to SM Energy’s assignment of its rights in this Agreement, which assignment shall be in a form reasonably acceptable to Buyer, and (b) pay the Purchase Price (or a designated portion thereof as specified by SM Energy) into a qualified escrow or qualified trust account(s) at Closing as directed in writing. If Buyer assigns all or any of its rights under this Agreement for this purpose, SM Energy agrees to (i) consent to Buyer’s assignment of its rights in this Agreement, which assignment shall be in a form reasonably acceptable to SM Energy, (ii) accept the Purchase Price from the qualified escrow or qualified trust account at Closing, and (iii) at Closing, convey and assign directly to Buyer the Assets (or any portion thereof) as directed by Buyer. SM Energy and Buyer acknowledge and agree that any assignment of this Agreement (or any rights hereunder) to a Qualified Intermediary shall not release any Party from any of its respective liabilities and obligations hereunder, and that neither Party represents to the other Party that any particular tax treatment will be given to any Party as a result thereof. The Party electing to assign all or any of its rights under this Agreement pursuant to this Section 2.7 shall defend, indemnify, and hold harmless the other Party and its Affiliates from all claims, costs, losses and expenses relating to such election.

ARTICLE VI

TITLE MATTERS; CASUALTIES

6.1 SM Energy’s Title.

Without limiting Buyer’s remedies for Title Defects set forth in this Article VI, except for the Subject Special Warranty, SM Energy makes no warranty or representation, express, implied, statutory or otherwise with respect to its title to any of the Assets and Buyer hereby acknowledges and agrees that Buyer’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Assets shall be as set forth in Section 6.2.

6.2 Notice of Title Defects; Defect Adjustments.

(a) Title Defect Notices. On or before 4:00 p.m. (Mountain Time) on November 21, 2016 (the “Defect Claim Date”), Buyer shall have the right, but not the obligation, to deliver notices to SM Energy meeting the requirements of this Section 6.2(a) (each, a “Title Defect Notice”) setting forth any matters which, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer asserts as a Title Defect pursuant to this Section 6.2. For all purposes of this Agreement and notwithstanding anything herein to the contrary, except with respect to the Subject Special Warranty and/or claims pursuant to Section 8.1 (solely as to matters occurring between the Execution Date and the Closing Date), Buyer shall be deemed to have waived, and SM Energy shall have no liability for, any Title Defect that Buyer fails to assert as a Title Defect pursuant to a Title Defect Notice delivered in material compliance with

this Section 6.2(a) and received by SM Energy on or before the Defect Claim Date. To be effective, each Title Defect Notice shall be in writing and shall include (i) a description of the alleged Title Defect and the Assets affected by such Title Defect (each a “Title Defect Property”), (ii) the Allocated Value of each Title Defect Property, (iii) supporting documents reasonably necessary for SM Energy to verify the existence of the alleged Title Defect(s), (iv) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s), and (v) the computations upon which Buyer’s belief is based. To give SM Energy an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use reasonable efforts to give SM Energy, on or before the end of each calendar week prior to the Defect Claim Date, written reports of alleged Title Defects discovered by Buyer during the preceding calendar week, which reports may be preliminary in nature and supplemented prior to the expiration of the applicable Defect Claim Date, provided that the failure to provide such reports shall not waive Buyer’s rights to provide a Title Defect Notice prior to the Defect Claim Date for any Title Defect. Buyer shall also promptly furnish SM Energy with written notice of any Title Benefit that is discovered by Buyer or any Buyer’s Representative while conducting Buyer’s due diligence with respect to the Assets prior to the Defect Claim Date.

(b) Title Benefit Notices. SM Energy shall have the right, but not the obligation, to deliver to Buyer on or before the Defect Claim Date, a notice setting forth any matters that, in SM Energy’s reasonable opinion, constitute Title Benefits and that SM Energy asserts as a Title Benefit pursuant to this Section 6.2 (each, a “Title Benefit Notice”) including a description of the Title Benefit and the Assets affected by the Title Benefit (the “Title Benefit Property”), the amount by which SM Energy reasonably believes the Allocated Value of the Title Benefit Property is increased by the Title Benefit, (iii) supporting documents reasonably necessary for Buyer to verify the existence of the alleged Title Benefit and (iv) the computations upon which SM Energy’s belief is based. SM Energy shall be deemed to have waived all Title Benefits of which it, or Buyer pursuant to Section 6.2(a), has not given notice on or before the Defect Claim Date.

(c) Remedies for Title Defects. Subject to SM Energy’s continuing right to dispute the existence of a Title Defect or the Title Defect Amount asserted with respect thereto and subject to the Individual Title Defect Threshold and the Aggregate Deductible, in the event that any Title Defect properly asserted by Buyer in accordance with Section 6.2(a) is not waived in writing by Buyer or cured on or before Closing, SM Energy shall, at its sole option, elect to:

(i) transfer, convey and assign the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets, to Buyer at Closing, and reduce the Purchase Price by the Title Defect Amount;

(ii) transfer, convey and assign the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets, to Buyer at Closing, in which event SM Energy shall have the right, for a period of 110 days following the Closing Date (such period, the “Cure Period”), to cure any Title Defect relating to such retained Title Defect Property, and should SM Energy cure such Title Defect during the Cure Period, then the Purchase Price shall not be adjusted. If SM Energy is unable to cure any such Title Defect during the Cure Period, then the Purchase Price shall be reduced by an amount equal to the Title Defect Amount;

(iii) if agreed to by Buyer in writing, transfer, convey and assign the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets, to Buyer at Closing, and indemnify Buyer against all Liability resulting from such Title Defect with respect to the Assets pursuant to an indemnity agreement mutually agreeable to the Parties; or

(iv) at Closing, retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets and all rights to operate such retained Assets, and reduce the Purchase Price by an amount equal to the Allocated Value of such Title Defect Property and associated Assets;

provided, however, if a Title Defect is a “most favored nations” clause in a Lease, or related to an Unreviewed Material Contract, then Buyer’s sole and exclusive remedy for such Title Defect shall be to exclude the affected Leases or Assets, and all associated Assets, in which case the provisions of Section 6.2(c)(iv) shall apply.

(d) Remedies for Title Benefits. With respect to each Well or Well Location affected by Title Benefits reported under this Section 6.2, the aggregate Title Defect Amounts shall be decreased by an amount equal to the increase in the Allocated Value for such Asset caused by such Title Benefits, as determined pursuant to Section 6.2(g) (the “Title Benefit Amount”). The Title Benefit Amounts may only be used to offset Title Defect Amounts and may not increase the Purchase Price.

(e) Exclusive Remedy. The provisions set forth in Section 6.2(c) and Section 6.2(i), shall be the exclusive right and remedy of Buyer with respect to SM Energy’s failure to have Defensible Title with respect to any Asset, except for the Subject Special Warranty and/or claims pursuant to Section 8.1 (solely as to matters occurring between the Execution Date and the Closing Date).

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

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

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

(iii) if the Title Defect represents a discrepancy between (A) the Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest for such Title Defect Property stated in Exhibit B, and the Working Interest attributable to such Title Defect Property has been reduced proportionately, then the Title Defect Amount

shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the positive difference between such Net Revenue Interest values, and the denominator of which is the Net Revenue Interest for such Title Defect Property stated in Exhibit B, provided that if the Net Revenue discrepancy does not affect the Title Defect Property throughout its entire life, the Title Defect Amount determined under this Section 6.2(f) shall be reduced to take into account the applicable time period only;

(iv) if the Title Defect represents an obligation or Encumbrance upon or other defect in title to the Title Defect Property of a type not described above, including a Title Defect that represents a discrepancy between (A) the Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest for such Title Defect Property stated in Exhibit B, and the Working Interest attributable to such Title Defect Property has not been reduced proportionately, the applicable Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Buyer and SM Energy and such other reasonable factors as are necessary to make a proper evaluation;

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

(vi) notwithstanding anything to the contrary in this Article VI, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any single Title Defect Property shall not exceed the Allocated Value of such Title Defect Property, except (but subject to SM Energy’s rights under Sections 6.2(c)(ii), 6.2(c)(iii) and 6.2(c)(iv)) if a Title Defect is a lien, mortgage or deed of trust, the Title Defect Amount shall be the amount necessary to remove such mortgage, deed of trust or lien (provided that this exception shall not apply to mortgages, deeds of trust or liens granted by the lessors under the Leases, unless there is a default thereunder or foreclosure proceedings pursuant thereto).

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

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

(ii) if the Title Benefit represents an increase between (A) the Net Revenue Interest for any Title Benefit Property and (B) the Net Revenue Interest for such Title Benefit Property stated in Exhibit B, and the Working Interest has increased proportionately, then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property multiplied by a fraction, the numerator of which is

the positive difference between such Net Revenue Interest values, and the denominator of which is the Net Revenue Interest for such Title Benefit Property stated in Exhibit B, provided that if the Net Revenue increase does not affect the Title Benefit Property throughout its entire life, the Title Benefit Amount determined under this Section 6.2(g) shall be reduced to take into account the applicable time period only;

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

(iv) the Title Benefit Amount with respect to a Title Benefit Property shall be determined without duplication of any items or amounts included in any other Title Benefit Amount hereunder.

(h) Title Threshold and Deductibles. Notwithstanding anything to the contrary, in no event shall there be any adjustments to the Purchase Price or other remedies provided by SM Energy hereunder or under the Assignment: (i) for any individual Title Defect for which the Title Defect Amount does not exceed the Individual Title Defect Threshold and (ii) for any Title Defect for which the Title Defect Amount exceeds the Individual Title Defect Threshold unless the sum of the aggregate Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold (excluding any Title Defect Amounts attributable to Title Defects cured by SM Energy), exceeds the Aggregate Title Deductible, after which point Buyer shall be entitled to adjustments to the Purchase Price only with respect to such Title Defects in excess of the Aggregate Title Deductible. For the avoidance of doubt, if SM Energy elects to transfer, convey and assign any Title Defect Property pursuant to Section 6.2(c)(ii), the Purchase Price shall not be reduced by the Title Defect Amount of such Title Defect Property and the Title Defect Amount relating to such Title Defect Property will not be counted toward the Aggregate Title Deductible, unless SM Energy is unable to cure such Title Defect during the Cure Period, in which case the Purchase Price shall be adjusted as provided in Section 6.2(c)(ii). If a single Title Defect or series of related Title Defects affects several Well Locations in the same drilling or spacing unit, then such Title Defect(s) shall be deemed to have exceeded the Individual Title Defect Threshold if the total amount by which such Title Defect(s) reduce(s) the Allocated Value(s) of all the affected Well Locations exceed(s) the Individual Title Defect Threshold.

(i) Title Dispute Resolution. The Parties agree to resolve disputes concerning the following matters pursuant to this Section 6.2(i): (1) the existence and scope of a Title Defect or Title Defect Amount, (2) the adequacy of SM Energy’s Title Defect curative materials and Buyer’s reasonable satisfaction thereof and (3) the existence and scope of a Title Benefit or Title Benefit Amount (collectively, “Title Disputed Matters”). The Parties agree to attempt to initially resolve all disputes through good faith negotiations. If the Parties cannot resolve disputes regarding Title Disputed Matters, on or before Closing, the Closing shall be delayed as to only the Assets subject to the Title Disputed Matters until the Parties finally resolve the

dispute pursuant to this Section 6.2(i); provided, however, if either Party asserts that the condition in Section 9.1(d) or Section 9.2(d) has not been satisfied due, in whole or in part, to Title Defects, then the Parties will resolve all Title Disputed Matters pursuant to this Section 6.2(i) prior to Closing. In the event that neither Party asserts that the condition in Section 9.1(d) or Section 9.2(d) has not been satisfied, it is understood and agreed that the Parties shall proceed to Closing as contemplated herein as to all Assets not covered by a Title Disputed Matter. The Title Disputed Matters will be finally determined pursuant to this Section 6.2(i). There shall be a single arbitrator, who shall be an attorney with at least 10 years’ experience in oil and gas title and transactional matters, as selected by mutual agreement of Buyer and SM Energy within 15 days after any Party invokes the provisions of this Section 6.2(i) to resolve such Dispute, and absent such agreement, by the Houston office of the AAA (the “Title Arbitrator”). The arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the AAA Rules to the extent such rules do not conflict with the terms of this Section 6.2(i). The Title Arbitrator’s determination shall be made within 20 days after submission by the Parties of the matters in Dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the rules set forth in Section 6.2(f) and Section 6.2(g) and, subject to the foregoing, may consider such other matters as in the opinion of the Title Arbitrator are necessary to make a proper determination. The Title Arbitrator, however, may not award (a) Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in the applicable Title Defect Notice (which such Title Defect Amount shall not exceed the Allocated Value of the applicable Title Defect Property) or (b) SM Energy a greater Title Benefit Amount than the Title Benefit Amount claimed by SM Energy in the applicable Title Benefit Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect, Title Benefit, Title Defect Amount or Title Benefit Amount submitted by either Party and may not award damages, interest or penalties to either Party with respect to any Dispute. SM Energy and Buyer shall each bear its own legal fees and other costs of presenting its case to the Title Arbitrator. Each of SM Energy and Buyer shall bear one-half of the costs and expenses of the Title Arbitrator. To the extent that the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount was not taken into account as an adjustment to the Purchase Price or the aggregate Title Defect Amounts, as applicable at Closing pursuant to Section 2.4 and an adjustment would otherwise be required under the provisions of Section 6.2(c) or Section 6.2(d), as applicable, then, within 10 days after the Title Arbitrator delivers written notice to Buyer and SM Energy of its award with respect to such Title Defect Amount or a Title Benefit Amount and subject to Section 6.2(h), the Purchase Price will be adjusted pursuant to Section 2.4 by the amount so awarded by the Title Arbitrator.

6.3 Casualty or Condemnation Loss.

(a) Notwithstanding anything herein to the contrary, from and after the Effective Time, if Closing occurs, Buyer shall assume all risk of loss with respect to (i) production of Hydrocarbons from the Assets through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and (ii) the depreciation of personal property due to ordinary wear and tear and, in each case, Buyer shall not assert such matters as Casualty Losses or Title Defects hereunder.

(b) If, from and after the Effective Time but prior to the Closing Date, any portion of the Assets is damaged or destroyed by fire or other casualty or is taken in

condemnation or under right of eminent domain (a “Casualty Loss”), and the resulting loss from such Casualty Loss exceeds $100,000 based on the Allocated Value of the affected Assets, then (i) Buyer shall nevertheless be required to close the transactions contemplated by this Agreement and (ii) SM Energy shall elect by written notice to Buyer prior to Closing to either (A) cause, at SM Energy’s sole cost and as promptly as reasonably practicable (which work may extend after the Closing Date), each Asset affected by such Casualty Loss to be repaired or restored to at least its condition prior to such casualty or taking, or (B) reduce the Purchase Price by the cost to repair or restore each Asset affected by such Casualty Loss to at least its condition prior to such casualty or taking. In each case, SM Energy shall retain all rights to insurance, condemnation awards and other claims against third parties with respect to the casualty or taking except to the extent the Parties otherwise agree in writing.

6.4 Preferential Rights and Consents to Assign.

(a) All consents to assign relating to the Assets (“Consents”) and preferential rights to purchase (“Preferential Rights”) are listed on Schedule 6.4. The remedies set forth in this Section 6.4 are the exclusive remedies under this Agreement related to the Consents and Preferential Rights.

(b) From and after the Execution Date up to Closing, SM Energy shall use its commercially reasonable efforts (with the cooperation of Buyer) to obtain all Consents and waivers of all Preferential Rights (excluding any Customary Post-Closing Consents); provided, however, that neither Party shall be required to incur any Liability or pay any money in order to obtain such Consents or waivers.

(c) Preferential Rights. SM Energy shall, within 10 days after the Execution Date, send to each holder of a Preferential Right a notice requesting the election or waiver by each such holder of its applicable Preferential Right, in each case in material compliance with the contractual provisions applicable to such Preferential Right, requesting a waiver of such right. Any Preferential Right must be exercised subject to all terms and conditions set forth in this Agreement, including the successful Closing of this Agreement pursuant to Article XI. The consideration payable under this Agreement for any particular Asset for purposes of Preferential Right notices shall be the Allocated Value of such Asset.

(i) All Assets burdened by Preferential Rights for which (A) the applicable Preferential Right has been waived, or (B) the period to exercise such Preferential Right has expired prior to the Closing without the applicable holder of such Preferential Right electing to enforce its Preferential Right, shall, in each case, be assigned to Buyer at the Closing pursuant to the provisions of this Agreement.

(ii) If, prior to the Closing (A) any holder of a Preferential Right notifies SM Energy that it intends to consummate the purchase of the portion of the Assets to which its Preferential Right applies or (B) the time for exercising a Preferential Right has not expired and the holder of such Preferential Right has not waived such Preferential Right, then, in each case, such portion of the Assets affected by such Preferential Right shall be excluded from the Assets to be conveyed to Buyer at Closing and the Purchase Price shall be reduced by the Allocated Value of such excluded portion

of the Assets. SM Energy shall be entitled to all proceeds paid by a Person exercising a Preferential Right prior to the Closing. If, after the Closing but prior to the date of final settlement of the Purchase Price under Section 2.6, (1) such holder of such Preferential Right thereafter fails to consummate the purchase of the portion of the Assets covered by such Preferential Right or (2) the time for exercising such Preferential Right expires without exercise by the holder thereof, then SM Energy shall (x) so notify Buyer and (y) on or before 10 days following delivery of such notice, assign such portion of the Assets to Buyer pursuant to an assignment in substantially the form of the Assignment and the Purchase Price shall be increased by an amount equal to the Allocated Value of such portion of the Assets.

(d) Consents. SM Energy, within 10 days after the Execution Date, shall send to each holder of a Consent a notice seeking such holder’s consent to the transactions contemplated hereby.

(i) If (A) SM Energy fails to obtain a Consent prior to Closing and the failure to obtain such Consent would cause (1) the assignment to Buyer of any portion of the Assets to be void or expose Buyer to material damages or (2) the termination of a Lease under the express terms thereof or (B) a Consent requested by SM Energy is denied in writing, then, in each case, that portion of the Assets affected by such Consent shall be excluded from the Assets to be conveyed to Buyer at Closing and the Purchase Price shall be reduced by the Allocated Value of such portion of the Assets. In the event that a Consent that was not obtained prior to Closing is obtained following Closing but prior to the final settlement of the Purchase Price under Section 2.6 or the requirement to obtain such Consent is waived by Buyer then, within 10 days after such Consent is obtained or the requirement to obtain such Consent is waived by Buyer, (x) SM Energy shall assign such excluded portion of the Assets to Buyer pursuant to an assignment in substantially the form of the Assignment (and if the requirement to obtain a Consent is waived by Buyer, Buyer shall have no claim against, and SM Energy shall have no Liability for, the failure to obtain such Consent), and (y) Buyer shall pay to SM Energy by wire transfer of immediately available funds an amount equal to the Allocated Value of such portion of the Assets so assigned.

(ii) If (A) SM Energy fails to obtain a Consent prior to Closing and the failure to obtain such Consent would not cause (1) the assignment to Buyer of any portion of the Assets to be void or expose Buyer to material damages or (2) the termination of a Lease under the express terms thereof and (B) such Consent requested by SM Energy is not denied in writing, then that portion of the Assets subject to such Consent shall be assigned by SM Energy to Buyer at Closing pursuant to the Assignment and Buyer shall have no claim against, and SM Energy shall have no Liability for, the failure to obtain such Consent.

ARTICLE VII

ENVIRONMENTAL MATTERS

7.1 Environmental Defects.

(a) Environmental Defects Notice. On or before the Defect Claim Date, Buyer shall have the right, but not the obligation, to deliver notices to SM Energy materially meeting the requirements of this Section 7.1(a) (each, an “Environmental Defect Notice”) setting forth any matters that, in Buyer’s reasonable opinion, constitute Environmental Defects and that Buyer asserts as Environmental Defects pursuant to this Section 7.1. For all purposes of this Agreement, Buyer shall be deemed to have waived any Environmental Defect that Buyer fails to properly assert as an Environmental Defect pursuant to an Environmental Defect Notice delivered in accordance with this Section 7.1(a) and received by SM Energy on or before the Defect Claim Date, except for claims relating to a breach of Section 3.12, or claims pursuant to Section 8.1 (solely as to matters occurring between the Execution Date and the Closing Date), Section 13.2(d), and/or Section 13.2(g). To be effective, each Environmental Defect Notice shall be in writing and shall include: (i) a description of the Environmental Condition constituting the alleged Environmental Defect, including the Environmental Law(s) violated by such Environmental Defect, (ii) each Asset (or portion thereof) affected by the alleged Environmental Defect (the “Environmental Defect Property”), (iii) the Allocated Value of each Environmental Defect Property, (iv) supporting documents in the possession of Buyer reasonably necessary for SM Energy to verify the existence of the alleged Environmental Defect, and (v) a calculation of the Remediation Amount (itemized in reasonable detail) that Buyer asserts is attributable to such alleged Environmental Defect. Buyer’s calculation of the Remediation Amount included in the Environmental Defect Notice must describe in reasonable detail the Remediation proposed for the Environmental Condition that gives rise to the asserted Environmental Defect and identify all assumptions used by Buyer in calculating the Remediation Amount, including the standards that Buyer asserts must be met to comply with Environmental Laws. SM Energy shall have the right, but not the obligation, to cure any claimed Environmental Defect on or before Closing. To give SM Energy an opportunity to commence reviewing and curing Environmental Defects, Buyer agrees to use reasonable efforts to give SM Energy, on or before the end of each calendar week prior to the Defect Claim Date, written report of all alleged Environmental Defects discovered by Buyer during the preceding calendar week, which reports may be preliminary in nature and supplemented prior to the expiration of the applicable Defect Claim Date, provided, however, that the failure to provide such reports shall not waive Buyer’s rights to provide an Environmental Defect Notice prior to the Defect Claim Date for any Environmental Defect, unless Buyer’s failure materially prejudices SM Energy’s ability to cure an Environmental Defect prior to Closing.

(b) Remedies for Environmental Defects. Subject to SM Energy’s continuing right to dispute the existence of an Environmental Defect or the Remediation Amount asserted with respect thereto and subject to the Individual Environmental Threshold and the Aggregate Deductible, in the event that any Environmental Defect timely asserted by Buyer in accordance with Section 7.1(a) is not waived in writing by Buyer or cured on or before Closing, SM Energy shall, at its sole option, elect to:

(i) reduce the Purchase Price by the Remediation Amount for such Environmental Defect;

(ii) retain the entirety of the Environmental Defect Property subject to such Environmental Defect, together with all associated Assets, and reduce the Purchase Price by an amount equal to the Allocated Value of the Environmental Defect Property and associated Assets; or

(iii) with the prior written consent of Buyer, indemnify Buyer against all Liability resulting from such Environmental Defect with respect to the Assets pursuant to an indemnity agreement in a form mutually agreeable to the Parties.

If SM Energy elects the option set forth in clause (i) above, Buyer shall be deemed to have assumed responsibility for all costs and expenses attributable to the Remediation of the applicable Environmental Defect (net to the Assets) and all Liabilities (net to the Assets) with respect thereto, and Buyer’s obligations with respect to the foregoing shall be deemed to constitute part of the Assumed Obligations.

(c) Exclusive Remedy. Subject to Buyer’s remedy for a breach of SM Energy’s representation contained in Section 3.12 or for claims pursuant to Section 8.1 (solely as to matters occurring between the Execution Date and the Closing Date), Section 13.2(d) or 13.2(g), Section 7.1(b) shall be the exclusive right and remedy of Buyer with respect to any Environmental Defect.

(d) Environmental Deductibles. Notwithstanding anything to the contrary, in no event shall there be any adjustments to the Purchase Price or other remedies provided by SM Energy for (i) any individual Environmental Defect for which the Remediation Amount does not exceed the Individual Environmental Threshold, or (ii) any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Threshold, unless the sum of (A) the aggregate Remediation Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold (excluding any Remediation Amounts attributable to (1) Environmental Defects cured by SM Energy or (2) Environmental Defect Properties that SM Energy elects to retain pursuant to Section 7.1(b)(ii)), exceeds the Aggregate Environmental Deductible, after which point Buyer shall only be entitled to adjustments to the Purchase Price with respect to such Environmental Defects in excess of the Aggregate Environmental Deductible. For the avoidance of doubt, if SM Energy elects to retain any Asset pursuant to Section 7.1(b)(ii), the Purchase Price shall be reduced by the Allocated Value of such retained Asset and the Remediation Amount for the Environmental Defect relating to such retained Asset will not be counted towards the Aggregate Environmental Deductible. If a single Environmental Defect or series of related Environmental Defects affects several Well Locations in the same drilling or spacing unit, then such Environmental Defect(s) shall be deemed to have exceeded the Individual Environmental Threshold if the total amount by which such Environmental Defect(s) reduce(s) the Allocated Value(s) of all the affected Well Locations exceed(s) the Individual Environment Threshold.

(e) Environmental Dispute Resolution. The Parties agree to resolve disputes concerning the existence and scope of an Environmental Defect or Remediation Amount

pursuant to this Section 7.1(e) (the “Environmental Disputed Matters”). The Parties agree to attempt to initially resolve all disputes through good faith negotiations. If the Parties cannot resolve disputes regarding Environmental Disputed Matters on or before Closing, the Closing shall be delayed as to only the Assets subject to the Environmental Disputed Matters until the Parties finally resolve the dispute pursuant to this Section 7.1(e); provided, however, if either Party asserts that the condition in Section 9.1(d) or Section 9.2(d) has not been satisfied due, in whole or in part, to Environmental Defects, then the Parties will resolve all Environmental Disputed Matters pursuant to this Section 7.1(e) prior to Closing. In the event that neither Party asserts that the condition in Section 9.1(d) or Section 9.2(d) has not been satisfied, it is understood and agreed that the Parties shall proceed to Closing as contemplated herein as to all Assets not covered by an Environmental Disputed Matter. The Environmental Disputed Matters will be finally determined pursuant to this Section 7.1(e). There will be a single arbitrator, who must be an environmental attorney with at least 10 years’ experience in environmental matters involving oil and gas properties, as selected by mutual agreement of Buyer and SM Energy within 15 days after any Party invokes the provisions of this Section 7.1(e) to resolve such Dispute, and absent such agreement, by the Houston office of the AAA (the “Environmental Arbitrator”). The arbitration proceeding will be held in Houston, Texas and conducted in accordance with the AAA Rules to the extent such rules do not conflict with the terms of this Section 7.1(e). The Environmental Arbitrator’s determination must be made within 20 days after submission of the matters in Dispute and shall be final and binding upon both Parties, without right of appeal. In making its determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 7.1 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award Buyer a greater Remediation Amount than the Remediation Amount claimed by Buyer in the applicable Environmental Defect Notice (which such award shall not exceed the Allocated Value of the applicable Environmental Defect Property). The Environmental Arbitrator will act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. SM Energy and Buyer will each bear its own legal fees and other costs of presenting its case. Each Party will bear one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Purchase Price at Closing pursuant to Section 2.4 and Buyer would otherwise be entitled to an adjustment under the provisions of Section 7.1(d), then, within 10 days after the Environmental Arbitrator delivers written notice to Buyer and SM Energy of such award and subject to Section 7.1(d), the Purchase Price will be adjusted pursuant to Section 2.4 by such Remediation Amount.

7.2 NORM, Wastes and Other Substances.

Buyer acknowledges that the Assets have been used for exploration, development and production of oil and gas and that there may be petroleum, produced water, wastes or other substances or materials located in, on or under or associated with the Assets. Equipment and sites included in the Assets may contain asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of wells, materials and equipment as scale, or in other forms. The wells, materials and equipment located on the Assets or included in the Assets may contain

NORM and other wastes or Hazardous Substances. NORM containing material or other wastes or Hazardous Substances may have come in contact with various environmental media, including without limitation, water, soils or sediment. Special procedures may be required for the assessment, remediation, removal, transportation or disposal of environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Assets.

ARTICLE VIII

CERTAIN AGREEMENTS

8.1 Conduct of Business.

Except (x) as set forth in Schedule 8.1, (y) as expressly contemplated by this Agreement or (z) as expressly consented to in writing by Buyer, SM Energy agrees that from and after the Execution Date up to Closing:

(a) SM Energy will, and will cause its Affiliates to:

(i) maintain, and if SM Energy is the Operator thereof, operate, the Assets in the usual, regular and ordinary manner consistent with its past practice;

(ii) maintain insurance coverage on the Assets presently furnished by nonaffiliated third parties in the amounts and of the types presently in force;

(vi) commit to do any of the foregoing.

Buyer acknowledges that SM Energy owns undivided interests in certain of the Assets with respect to which it is not the Operator, and Buyer agrees that the acts or omissions of the other Working Interests owners (including the Third Party Operators) who are not SM Energy shall not constitute a breach of the provisions of this Section 8.1, and no action required pursuant to a vote of Working Interest owners shall constitute a breach of the provisions of this Section 8.1 so long as SM Energy voted its interest in such a manner that complies with the provisions of this Section 8.1.

8.2 Governmental Bonds.

Buyer acknowledges that none of the bonds, letters of credit and guarantees, if any, posted by SM Energy or its Affiliates with Governmental Authorities and relating to the Assets are transferable to Buyer. At or prior to Closing, Buyer shall deliver to SM Energy evidence of the posting of bonds or other security with all applicable Governmental Authorities meeting the requirements of such Governmental Authorities to own the Assets.

8.3 Notifications.

The provisions of this Agreement relating to representations, warranties, indemnities and agreements of the Parties shall not be altered or modified by Buyer’s knowledge or SM Energy’s Knowledge, as applicable, of any event or Buyer’s or SM Energy’s review of any documents or other matters except as expressly provided herein to the contrary.

8.4 Financial Cooperation.

(a) From and after the Execution Date, SM Energy shall cooperate with Buyer, its Affiliates and Buyer’s and its Affiliate’s auditors (“Buyer’s Auditors”) in connection with the preparation of any financial statements of Buyer or pertaining to the Assets and any

related pro forma financial statements or other financial information, and the conduct of audits or reviews of such financial statements, required under federal securities Laws or rules and regulations of the Securities and Exchange Commission (“SEC”) or under customary practice for securities offerings made pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), in connection with (a) any filing by Buyer or any of its Affiliates with the SEC pursuant to the Securities Act or the Securities Exchange Act of 1934, as amended, or (b) any offering memorandum or similar document relating to a private offering of securities of Buyer or its Affiliates pursuant to Rule 144A under the Securities Act or otherwise. In connection with such cooperation, from and after the Execution Date, SM Energy shall: (i) provide to Buyer, its Affiliates, and Buyer’s Auditors reasonable access to the books, records, information, and documents that are related to the Assets and SM Energy that are in SM Energy’s possession or control reasonably required by Buyer, its Affiliates, and Buyer’s Auditors in order to prepare, audit, and review such financial statements and other financial information; (ii) provide to Buyer, its Affiliates, and Buyer’s Auditors reasonable access to SM Energy’s officers, managers, employees, agents, and representatives who were responsible for preparing or maintaining the financial records and work papers and other supporting documents used in the preparation of such financial statements; (iii) deliver one or more customary representation letters from SM Energy to such Buyer’s Auditors that are reasonably requested to allow such Buyer’s Auditors to complete an audit or review of any such financial statements and to issue an opinion acceptable to such Buyer’s Auditors with respect to an audit or review of such financial statements; and (iv) use its reasonable best efforts to obtain the consent of the independent auditor of SM Energy that conducted any audit of such financial statements to the use of such independent auditor’s report, and to be named as an expert or as having prepared such report, in any SEC filing or offering memorandum or similar document referred to above.

(b) All of the information provided by SM Energy pursuant to this Section 8.4 is given without any representation or warranty, express or implied, and no member of the SM Indemnified Parties or SM Energy’s auditors shall have any liability or responsibility with respect thereto. Buyer, for itself and for each member of the Buyer Indemnified Parties, hereby releases, remises, and forever discharges each member of the SM Indemnified Parties and SM Energy’s auditors from any and all Proceedings, and Losses whatsoever, in law or in equity, known or unknown, which any member of the Buyer Indemnified Parties might now or subsequently may have, based on, relating to, or arising out of SM Energy’s obligations and actions pursuant to this Section 8.4, except to the extent that such Proceedings, or Liabilities resulted from willful misconduct of any SM Indemnified Party. From and after Closing, Buyer shall indemnify, defend, and hold harmless the SM Indemnified Parties and SM Energy’s auditors from and against any and all Losses arising out of or relating to SM Energy’s obligations and actions pursuant to this Section 8.4, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT, OR CONCURRENT), STRICT LIABILITY, OR OTHER LEGAL FAULT OF ANY INDEMNIFIED PERSON, EXCEPT TO THE EXTENT THAT SUCH LOSSES RESULTED FROM THE WILLFUL MISCONDUCT OF ANY SM INDEMNIFIED PARTY.

ARTICLE IX

The obligations of Buyer to consummate the transactions contemplated by this Agreement are subject to the fulfillment (or waiver by Buyer) on or prior to the Closing of each of the following conditions:

(a) Representations. The representations and warranties of SM Energy set forth in Article III shall be true and correct in all respects (other than those representations and warranties of SM Energy that are qualified by materiality, which shall be true and correct in all respects) as of the Closing Date as though made on and as of the Closing Date (other than representations and warranties that refer to a specified date, which need only be true and correct on and as of such specified date), except for those breaches, if any, of such representations and warranties that in the aggregate would not have a Material Adverse Effect.

(b) Performance. SM Energy shall have materially performed or complied with all obligations, agreements and covenants contained in this Agreement as to which performance or compliance by SM Energy is required prior to or at the Closing Date.

(c) No Legal Proceedings. No material Proceeding instituted by a third party shall be pending before any Governmental Authority seeking to restrain, prohibit, enjoin or declare illegal, or seeking substantial damages in connection with, the transactions contemplated by this Agreement.

TAX MATTERS

10.1 Asset Tax Liability.

Subject to the treatment of ad valorem Taxes provided below, all Asset Taxes shall be allocated between Buyer and SM Energy as of the Effective Time for all taxable periods that include the Effective Time. All Asset Taxes that are not ad valorem taxes shall be allocated to SM Energy to the extent they relate to production prior to the Effective Time and to Buyer to the extent they

relate to production on or after the Effective Time. No liability for Asset Taxes shall duplicate an adjustment to Purchase Price made pursuant to Section 2.4. Ad valorem Taxes for each assessment period shall be allocated to SM Energy based on the percentage of the assessment period occurring before the Effective Time and to Buyer based on the percentage of the assessment period occurring on or after the Effective Time. Each Party shall promptly furnish to the other copies of any Asset Tax assessments and statements (or invoices therefor from the operator of the Assets) received by it to the extent such assessment, statement, or invoice relates to an Asset Tax allocable to the other Party under this Section 10.1. Each Party shall timely pay all Asset Taxes subject to allocation under this Section and shall furnish to the other Party evidence of such payment. The Parties shall estimate all Asset Taxes that are attributable to the ownership or operation of the Assets through the Closing Date and all Subject Transfer Taxes and incorporate such estimates into the Preliminary Settlement Statement. The actual amounts (to the extent the actual amounts differ from the estimates included in the Preliminary Settlement Statement and are known at the time of the Final Settlement Statement) shall be accounted for in the Final Settlement Statement. If the actual amounts are not known at the time of the Final Settlement Statement, the amounts shall be re-estimated based on the best information available at the time of the Final Settlement Statement. When the actual amounts are known, Buyer or SM Energy shall make such payments to the other (if any) as are necessary to effect the allocation of Taxes described in this Section 10.1.

10.2 Transfer Taxes.

All sales, use or other Taxes (other than Taxes on gross income, net income or gross receipts), duties, levies, recording fees or other governmental charges incurred by or imposed with respect to the property transfers undertaken pursuant to this Agreement (“Subject Transfer Taxes”) shall be the responsibility of, and shall be paid by, Buyer. The Parties shall reasonably cooperate in taking steps that would minimize or eliminate any Subject Transfer Taxes. Buyer agrees to file all Subject Transfer Tax Returns relating to such Subject Transfer Taxes.

10.3 Asset Tax Reports and Returns.

For Asset Tax periods in which the Effective Time occurs, SM Energy agrees to immediately forward to Buyer copies of any Asset Tax reports and Tax Returns received or filed by SM Energy after the Closing and provide Buyer with any information SM Energy has that is reasonably necessary for Buyer to file any required Tax Return related to the Assets. Buyer agrees to file all Tax Returns and reports applicable to the Assets that Buyer is required to file after the Closing and, subject to the provisions of Section 10.1, to pay all required Asset Taxes payable with respect to the Assets.

10.4 Tax Cooperation.

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

10.5 Indemnity Payments.

Buyer and SM Energy agree to treat any payment made pursuant to the indemnification provisions of this Agreement as an adjustment to the Purchase Price for Tax purposes.

ACQUISITION TERMINATION AND REMEDIES

12.1 Right of Termination.

This Agreement and the transactions contemplated herein may be terminated at any time at or prior to Closing:

(a) by SM Energy, if any of the conditions set forth in Section 9.2 (other than the conditions set forth in Section 9.2(d)) have not been satisfied by Buyer on or before December 30, 2016 (the “Outside Termination Date”);

(b) by Buyer, if any of the conditions set forth in Section 9.1 (other than the conditions set forth in Section 9.1(d)) have not been satisfied by SM Energy on or before the Outside Termination Date;

(c) by SM Energy if the condition set forth in Section 9.2(d) is not satisfied on or before the Outside Termination Date or by Buyer if the condition set forth in Section 9.1(d) has not been satisfied on or before the Outside Termination Date; or

(d) by the mutual written agreement of Buyer and SM Energy;

provided, however, that no Party shall have the right to terminate this Agreement pursuant to clause (a) or (b) above if such Party or its Affiliates are at such time in material breach of any provision of this Agreement.

12.2 Effect of Termination.

(a) If the obligation to close the transactions contemplated by this Agreement is terminated pursuant to any provision of Section 12.1, then, except as set forth in Section 12.2(b) and Section 12.2(c) and except for the provisions of (x) Section 2.3, Sections 5.1(c) through 5.1(g), Section 5.2, Section 5.3, this Section 12.2, Section 13.9, and Section 14.7, and (y) such terms as set forth in this Agreement in order to give context to any of the surviving Sections, this Agreement shall forthwith become void and the Parties shall have no liability or obligation hereunder, except and to the extent such termination results from the material breach by a Party of any of its covenants or agreements hereunder, in which case the non-breaching Party shall be entitled to the Deposit, damages, or specific performance as hereinafter provided.

(b) If this Agreement is terminated by SM Energy pursuant to Section 12.1(a), SM Energy has performed or is ready, willing and able to perform all of its agreements and covenants contained herein in all material respects which are to be performed or observed at Closing, and Buyer has failed to perform or observe any of its agreements or covenants contained herein which are to be performed or observed at Closing, then except for the remedies provided in Section 12.2(d), SM Energy shall receive and retain the Deposit as liquidated damages as SM Energy’s sole and exclusive remedy for any breach or failure to perform by Buyer under this Agreement, except for the indemnities provided in Section 5.1(c), and all other rights and remedies arising under this Agreement (except for the provisions that survive pursuant to Section 12.2(a), which shall remain in full force and effect) are hereby expressly waived by SM Energy. SM Energy and Buyer agree upon the Deposit as liquidated damages due to the difficulty and inconvenience of measuring actual damages and the uncertainty thereof, and SM Energy and Buyer agree that such amount would be a reasonable estimate of SM Energy’s loss in the event of any such breach or failure to perform by Buyer. In lieu of termination of this Agreement, subject to Section 13.9, SM Energy shall be entitled to specific performance of this Agreement as provided below.

(c) If this Agreement is terminated by Buyer pursuant to Section 12.1(b), Buyer has performed or is ready, willing and able to perform all of its agreements and covenants contained herein in all material respects which are to be performed or observed at Closing, and

SM Energy has failed to perform or observe any of its agreements or covenants contained herein which are to be performed or observed at Closing, SM Energy shall cause the Deposit to be returned to Buyer and Buyer shall be entitled to seek money damages from SM Energy available at Law for SM Energy’s applicable breach of this Agreement subject to Section 13.9, as Buyer’s sole and exclusive remedy for any breach or failure to perform by SM Energy under this Agreement (except for the remedies provided in Section 12.2(d)), and all other rights and remedies arising under this Agreement (except for the provisions that survive pursuant to Section 12.2(a), which shall remain in full force and effect) are hereby expressly waived by Buyer, and SM Energy shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of the Assets to any Person without any restriction under this Agreement. In lieu of termination of this Agreement, Buyer shall be entitled to specific performance of this Agreement as provided below.

(d) In lieu of termination of this Agreement, the Parties expressly agree that monetary damages will be insufficient to compensate them for their damages and as such each of Buyer and SM Energy agree that the Party with the right to terminate this Agreement shall in lieu thereof be entitled to exercise the remedy of specific performance under this Agreement. Prior to exercising the remedy of specific performance under this Agreement pursuant to this Section 12.2(d), the Party entitled thereto must deliver notice in writing to the other Party stating its election to exercise such remedy under this Section 12.2(d) within thirty (30) days counted from and after the Termination Date. If the Party entitled to exercise the remedy of specific performance elects to exercise such remedy pursuant to this Section 12.2(d), the Deposit shall continue to be held by the Escrow Agent, until a non-appealable final judgment or award on the claim of specific performance is rendered, or if specific performance is not granted, the Deposit shall be paid to the Party that was entitled to terminate this Agreement, or as otherwise provided in Section 2.3(b), as applicable. After such judgment is rendered, the Parties will issue a joint written instruction to the Escrow Agent to distribute the Deposit pursuant to such judgment. The Parties hereby agree not to raise, and hereby waive, any objections to the availability of the equitable remedy of specific performance to specifically enforce the terms and provisions of this Agreement or to enforce compliance with, the covenants and agreements of the Parties under this Agreement. The Party entitled to exercise specific performance as a remedy under this Agreement shall not be required to provide any bond or other security, or to prove irreparable injury or harm, in connection with seeking an injunction or injunctions to enforce specifically the terms and provisions of this Agreement. The Parties hereto further agree that (x) by seeking the specific performance provided for in this paragraph, including by the institution of a court proceeding, the Party entitled to seek such specific performance shall not in any respect waive its right to seek any other form of relief that may be available to it under this Agreement (including those related to termination of this Agreement) in the event that the specific performance provided for in this paragraph are not available or otherwise are not granted, and (y) nothing set forth in this paragraph shall require such Party to institute any proceeding for (or limit such Party’s right to institute a proceeding for) such remedies prior to or as a condition of exercising any termination right under this Section 12.2, nor shall the commencement of any proceeding pursuant to this paragraph restrict or limit such Party’s right to terminate this Agreement in accordance with this Section 12.2.

12.3 Return of Documentation and Confidentiality.

Upon termination of this Agreement, Buyer shall return to SM Energy all title, engineering, geological and geophysical data, environmental assessments or reports, maps and other information furnished by SM Energy to Buyer or, if not destroyed by Buyer, prepared by or on behalf of Buyer in connection with its due diligence investigation of the Assets, in each case, in accordance with the Confidentiality Agreement.

13.7 Indemnification Procedures.

All claims for indemnification under Section 5.1(c), Section 13.2 and Section 13.3 shall be asserted and resolved as follows:

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

(b) To make claim for indemnification under Section 5.1(c), Section 13.2 or Section 13.3, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 13.7, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a third party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 13.7 shall not relieve the Indemnifying Party of its obligations under Section 5.1(c), Section 13.2 or Section 13.3 (as applicable) except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise materially prejudices the Indemnifying Party’s ability to defend against the claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have fifteen (15) days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its liability to defend the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such fifteen (15) day period, at the expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party.

(d) If the Indemnifying Party admits its obligation to indemnify a Third Party Claim, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Third Party Claim provided that, where the Third Party Claim consists of (i) a civil, criminal or regulatory proceeding, action, indictment or investigation against the Indemnified Party by any Governmental Authority, (ii) a claim in which the Indemnifying Party is also a party and the Indemnified Party determines in good faith that joint representation would be inappropriate, or (iii) a claim that primarily seeks injunctive or other non-monetary or equitable relief against the Indemnified Party, the Indemnified Party shall at its option have the right to control the defense and proceedings. Except as provided in the preceding sentence, the Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Third Party Claim that the Indemnifying Party elects to contest (provided, however, that the Indemnified Party shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Party may participate in, but not control, at its own expense, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 13.7(d). An Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle any Third Party Claim or consent to the entry of any judgment with respect thereto that (i) does not result in a final resolution of the Indemnified

Party’s Liability in respect of such Third Party Claim (including in the case of a settlement an unconditional written release of the Indemnified Party from all Liability in respect of such Third Party Claim), (ii) results in a finding or admission of any violation of Law or the violation of the rights of any Person or subjects the Indemnified Party to other Third Party Claims or (iii) in any manner may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnification obligations hereunder).

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

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

13.8 Survival.

(a) The representations and warranties of SM Energy contained in this Agreement shall survive the Closing until the date that is the first anniversary date of the Closing Date and expire thereafter; provided however, that the Fundamental Representations shall survive until sixty (60) days following the expiration of the applicable statute of limitations period. The covenants and agreements of SM Energy and of Buyer contained in this Agreement to be performed prior to the Closing Date shall, in each case, survive the Closing until the date that is the first anniversary date of the Closing Date and expire thereafter, and all other covenants and agreements of SM Energy and Buyer contained in this Agreement shall survive the Closing until fully performed, subject however to applicable statutes of limitation. The representations and warranties of Buyer contained in Article IV shall survive the Closing without time limit, subject to applicable statutes of limitations.
